Abstract

The utility model relates to a rotary cutter shaft device. The rotary cutter shaft device comprises a cutter shaft (2); and a plurality of blades (2-1) are mounted on the excircle of the cutter shaft (2), and are spaced from one another through circular cutter cushions (3). The rotary cutter shaft device is characterized in that a rack wheel (1) and a pawl (7) meshed with each other are mounted at one end of the cutter shaft (2); the pawl (7) is connected with a fixing plate (5) through a tension spring (6); and a cutter shaft end cover (4) compressing the blades is arranged at the other end of the cutter shaft (2), and sleeved by a rotary wrench (8). The utility model has the advantages that the blades can be replaced without the shutdown of a machine, so that the machine can conduct normal production for a long time, which can reduce consumption and save resources.

Description

The swivel knife shaft device

Technical field

The utility model relates to a kind of swivel knife shaft device, belongs to the plastics machinery field, is mainly used in cutting plastic foil, sheet in the plastics machinery production process.

Background technology

At present existing plastics machinery to the process of resin production process in; usually can use the technology of cutting; and existing equipment adopts hilted broadsword to divide incision technology mostly; because the passivation of blade; time about one week just must be changed blade one time, and machine can not be produced continuously, causes the number of times of unplanned parking; waste a large amount of resources, make manufacturer's production cost improve.

Summary of the invention

The purpose of this utility model provides a kind of swivel knife shaft device of changing blade of realizing not shutting down.

The technical scheme that realizes above-mentioned purpose is: a kind of swivel knife shaft device, comprise the cutter shaft that a plurality of blades are installed on the cylindrical, and separate with circular edge bearing between the blade, one end of cutter shaft is equipped with ratchet (1) and the ratchet that is meshed, ratchet is connected with a fixed head by extension spring, and the other end of cutter shaft has on the cutter shaft end cap that compresses blade, the cutter shaft end cap and is set with rotary spanner.

After adopting technique scheme; utilize extension spring to hold ratchet; by rotary spanner rotating knife hubcap; and drive cutter shaft and rotate together, when the blade of changing when needs did not also break away from plastic film, the second blade on the swivel knife shaft had been cut an original point that cuts open; do not shut down the purpose of changing blade to reach; thereby make machine ordinary production for a long time, reduce consuming, economize on resources.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Shown in Fig. 1～12, a kind of swivel knife shaft device, comprise the cutter shaft 2 that a plurality of blade 2-1 are installed on the cylindrical, and separate with circular edge bearing 3 between the blade, one end of cutter shaft 2 is equipped with ratchet 1 and the ratchet 7 that is meshed, ratchet 7 is connected with a fixed head 5 by extension spring 6, and the other end of cutter shaft 2 has on the cutter shaft end cap 4 that compresses blade, the cutter shaft end cap 4 and is set with rotary spanner 8.Described blade 2-1 is more than 5 or 5.

Operation principle of the present utility model is as follows:

Load onto blade 2-1 on cutter shaft 2, the centre separates with circular edge bearing 3, loads onto ratchet 1 and ratchet 7 at an end of cutter shaft 2, and the other end of cutter shaft 2 compresses blade 2-1 by cutter shaft end cap 4, and blade 2-1 can not be become flexible.Utilize spring 6 to hold ratchet 7,, and drive cutter shaft 2 rotations then by rotary spanner 8 rotating knife hubcaps.When the blade of needs replacing did not also break away from plastic film, the second blade on the swivel knife shaft had been cut an original point that cuts open, and did not shut down the purpose of changing blade to reach.

The utility model utilizes the effect of rotary cutter, and making the time lengthening of changing a cutter originally weekly is more than one month, when rotary cutter is 5 slice structures, has been equivalent to prolong 5 times of original service times.For example, be 25Kg at every turn because of stopping the feed back that car produces, drive less so 4 times, just equal to have saved the raw material of 100Kg, also reduced a large amount of power consumptions, so energy-saving effect is very considerable.

Claims

1. swivel knife shaft device, comprise the cutter shaft (2) that a plurality of blades (2-1) is installed on the cylindrical, and separate with circular edge bearing (3) between the blade, it is characterized in that: an end of cutter shaft (2) is equipped with ratchet (1) and the ratchet (7) that is meshed, ratchet (7) is connected with a fixed head (5) by extension spring (6), and the other end of cutter shaft (2) has on the cutter shaft end cap (4) that compresses blade, the cutter shaft end cap (4) and is set with rotary spanner (8).

2. swivel knife shaft device according to claim 1 is characterized in that: it is more than 5 or 5 that cutter shaft (2) is gone up the blade of installing (2-1).
