Abstract

The utility model relates to a swinging-typed net-lapping machine, comprising a frame, a driving roller, and a fibre transmitting belt. The frame is provided with a flywheel provided with the connecting rod device of a crankshaft, and the frame is also provided with a swinging arm whose one end is provided with a swinging shaft and an eccentric pin sheathed with a hole on the connecting rod; the other end of the swinging arm is freely suspended; the transmission direction of the fibre transmitting belt is engaged with the direction of the symmetry shaft of the swinging arm. The net-lapping machine has small ground occupation, low energy consumption, and high net-lapping speed.

Description

Swing type lapping machine

The utility model belongs to makes fibrage be paved into fibroreticulate nonwoven machinery.

The fibrage that comes out from carding machine is an individual layer, and changing into multilayer (for example 10-20 layer) with single layer fibre layer shop becomes fiber web, and this process is called lapping, uses the lapping machine to finish.Fiber web is used to make bat or various industrial intermediate materials.

The reciprocating type lapping machine close with the utility model, its structure such as Fig. 1.(1) is oblique curtain among the figure, and (2) are the first curtain, and (3) are the second curtain, and (4) are third curtain, (5) fiber web for completing, and (6) are frame.Tiltedly curtain, first curtain, second curtain two ends have live-roller respectively, constitute the curtain that transmits fiber with the conduction band between two live-rollers, fiber is according to direction of arrow transmission among the figure, pass through oblique curtain (1), first curtain (2), second curtain (3) in turn, be delivered to third curtain (4), third curtain (4) is long-armed for the steel that moves reciprocatingly, it is heavy about 100 kilograms, rely on its reciprocating motion, the fiber that second curtain (3) is passed over is paved into net, and net is down back and forth piled up.Owing to rely on long-armed reciprocating lapping, make the machine floor space very big, machine self active length is about 8.5 meters.Because long-armed heaviness, power consumption is high, and long-armed per minute reciprocal time generally is no more than 15 times, and lapping speed is slow, yield poorly.

It is little that the purpose of this utility model is to design a kind of floor space, the fireballing lapping machine of energy savings and lapping.

The utility model adopts the technical scheme of swing type lapping.It comprises frame, is installed on the live-roller on the frame, the conduction curtain that constitutes by the transmitting fiber tow conduction band that is installed on the live-roller and as the motor of power source, it is characterized in that flywheel is installed on the frame, bent axle is housed on the flywheel, bent axle is connected with connecting rod one end, swing arm is housed on the frame in addition, swing arm first end is set on the balance staff, and this balance staff is loaded on the frame, and said swing arm first end is equipped with cam pin in addition, the said connecting rod other end is connected with cam pin, and swing arm second end freely suspends; Two pairs are set on the said balance staff by structural member by the pendulum curtain that live-roller and dress transmitting fiber tow conduction band thereon constitute; This two pair is put curtain parallel installation of symmetry axis direction along said swing arm, and becomes vertical the connection with swing arm face; Leave the crack that transmits single layer fibre between the two secondary pendulum curtains.The conduction orientation of said transmitting fiber tow conduction band connects in the street mutually with the symmetry axis direction of swing arm, and so-called symmetry axis means the central shaft from swing arm first end to second end.When the single layer fibre that comes out from carding machine is delivered to the frame other end forward on the transmitting fiber tow conduction band, transmit downwards along the crack between the two secondary pendulum curtains again, along with swinging of swing arm, single layer fibre is paved into fiber web.

The utility model is spread fiber web by swinging of swing arm, quite will have reciprocating type long-armed in the lapping machine now and change into and place the position vertically from the former position that keeps flat, and reduces floor space so greatly, and machine works length is kept to existing 3.7 meters by former 8.5 meters; The utility model makes full use of the inertia of effort-saving mechanism and swing arm own wt by flywheel, bent axle, connecting rod and cam pin and swing arm, saves energy consumption greatly; The linear velocity of existing reciprocating type lapping organic fiber conduction band is 24 meters of per minutes, and the utility model can reach 36 meters of per minutes; Existing reciprocating type lapping machine all need overhaul once after per tour work, and the maximum every monthly repairs of the utility model once because of reciprocal arm work heaviness.This shows that it is little to the utlity model has floor space, the power consumptive province, lapping speed is fast and good effect such as reliability height.

Fig. 1 is existing reciprocating type lapping machine figure;

Fig. 2 is the utility model installation drawing.

Below in conjunction with Fig. 2 the utility model is further specified.

See Fig. 2, (1) is frame, (2) be installed on live-roller on the frame, live-roller is by driving-chain auxiliary driving driven by motor, and (3) are for being installed on the conduction band on the live-roller, (4) be single layer fibre, (5) be driving chain, (6) are the main driving motor that joins with driving chain, and (7) are for being installed on the flywheel on the frame, crank is housed on the flywheel, and crank is connected with connecting rod (8) one ends; Swing arm (10) first ends are circular, are getting a bit on the swing arm symmetry axis and below the center of circle, and swing arm is loaded on the balance staff (11), and said balance staff (11) is loaded on the frame; Get a point apparatus cam pin (9) above the said center of circle, this cam pin is connected with connecting rod (8) other end, and swing arm second end freely suspends, main driving motor (6) passes through driving chain, the drive flywheel rotates, and the cam pin transmission by crankshaft-link rod and swing arm one end freely swings swing arm; Meanwhile, auxiliary driving motor (not shown) drives live-roller (2) by transmission device, and conduction band (3) begin to transmit, and makes single layer fibre (4) (3) past front transfer along the conduction band of coming out from carding machine.

Feature of the present invention also is to connect in the street mutually with the symmetry axis direction of swing arm for the conduction orientation that realizes the transmitting fiber tow conduction band, design two pairs by the pendulum curtain (12) that live-roller and dress transmitting fiber tow conduction band thereon constitute, be set on the said balance staff (11) by structural member; Said two pairs are put the symmetry axis direction parallel installations of curtains (12) along swing arm (10), and become vertical the connection with swing arm face; Leave the crack of conduction single layer fibre between the two secondary pendulum curtains (12).The live-roller at pendulum curtain (12) two ends by driving-chain by the auxiliary driving driven by motor.As shown in Figure 2, conduction band (3) forms the closed circulation transmission system along the frame inclined-plane, conduction band on the two secondary pendulum curtains (12) also becomes the closed circulation transmission system respectively, after single layer fibre (4) is delivered to beveled top end along conduction band (3), send into again in the crack between the two secondary pendulum curtains (12), continue down to transmit.Because two secondary pendulum curtains (12) are connected with swing arm is vertical, and a shared balance staff (11), two secondary pendulum curtains (12) are swung synchronously with swing arm (10), this realizes the down transmission of single layer fibre one side by force, one side is paved into fiber web (13) along with swinging of above-mentioned pendulum curtain back and forth piled up.
