V. Creation description (l) Belt-cutting machine [Technical field to which the new type belongs] This creation is related to the placement and activities of a band-saw blade, especially the protection of the lifting device, and the visual and Operation, the first structure of the saw blade protection lifting device [prior art] The improved guide sleeve of the machine's saw blade protection lifting device has a direct correspondence to the concave fold for reducing the volume of the product to reduce the line of sight and can effectively increase the use of a safe band saw. By.

For example, the new patent case No. 535β7γ of "Annex I" for the protection device of the band saw machine's lifting protection device, the lifting protection device is equipped with an L-shaped plate frame for racks and guides and wheels. The set is located at the operating wheel set in the machine base above the machine table. The gear driven by the operating wheel meshes with the rack, so that when the operating wheel is rotated, the guide sleeve can be driven to lift; ^ The purpose is to adjust the height depending on the different heights and thicknesses of the work, so that the bottom end of the main sleeve of the lifting device is as close as possible to the work surface. 'A sharply reduced accident and danger caused by the sharp band saw belt exposure. Only the length of the saw is exposed, so that it maintains the normal position of the saw belt during the sawing operation, reducing the offset or falling off, and it is absolutely positive for the smooth operation of the sawing operation.

Large, but its diagram shows that the volume of the main sleeve of the lifting device is equivalent to 1. When the workpiece is operated and pushed, it just blocks the visual and cutting place; the other movable cover is directly fitted with the main sleeve. Insertion for sliding has no effect except for ^, and the main sleeve itself must be stamped and welded by several pieces, and the processing and cost are high, so it is ideal and impractical.

M243290 V. Creation Instructions (2) * [New Content] This creation relates to the improvement of a saw blade protection lifting device for a band saw machine. The guide sleeve is correspondingly concavely folded into a band saw with a plate. And guiding notches, a concave notch is provided on the upper end of one side so that the guide sleeve will not interfere with the upper drive wheel after being raised; there is another long hole under the concave notch for the convex post of the movable cover to be inserted; the movable cover cooperates with the door The profile frame is set on the guide block, and the guide block is fixed on the notch at the bottom of the upper platform, so that the movable cover has a clear guiding effect when it is raised and lowered, and the guide sleeve is reduced to Good support effect at low points-to ensure that the band saw will not arbitrarily move during cutting; the guide sleeve has a simple and cost-effective structure, and greatly reduces the volume and has a small class segment, which makes the processing place The visual effect is much better than the conventional one to greatly reduce the trouble and inconvenience of processing, and has quite positive practical effects. [Embodiment] First, please refer to the fourth and fourth figures. The protective lifting device of this creation includes a guide sleeve (1), a movable cover (2) and a guide block (3). ), The guide wheel set (5), the operation wheel set (6), etc., and are arranged at the upper base (71) of the machine table (7). The guide sleeve (1) is a plate frame with a notch (1 1) at the front end corresponding to a plate folded correspondingly, and an L-shaped frame (1 2) is arranged at the rear end to cooperate with the block body (1 2 1) and the mounting hole (1 2 2) A rack (4) and a guide wheel set (5 __) are provided for the group; the bottom end of the guide sleeve (1) forms a smaller step section (1 3) toward the gap (11), and the rear end has A baffle (1 4) has a long hole (1 5) and a concave notch (1 6) on the baffle (1 4), respectively. The movable cover (2) has upper and lower baffles (21), (22),

Page 5 M243290 5. Creation instructions (3) and a convex post (2 3) on the other side can be placed in the long hole (1 5) for movement and displacement, and cooperate with the door frame (24) and many screws The solid element (2 5) passes through and is screwed and movable and is set in the concave guide groove (3 1) of the guide block (3) for movable lifting. Guide block (3) — In addition to the concave guide groove (3 1) at the end, several mounting holes (3 2) are provided to enable the guide block (3) to be set and fixed to the bottom plate (72) of the upper machine (7 1). ) And close to the notch (73), so that the integrated guide sleeve (1), movable cover (2), rack (4) and guide wheel set (5) can be combined with the operation wheel set (6). ) Are combined with each other, and the operation wheel (61) drives the gear (62) to mesh with the rack (4) to drive the guide sleeve (1) and the like for lifting. A pointer (4 1) is provided on the top of the rack (4), and an elongated hole (74) can be protruded from the end face of the upper table (7 1) after being assembled, and can be controlled with a scale (7 5) on one side. Display lift distance and size. The guide wheel set (5) uses the support (5 1) to set transverse rollers (52) and straight rollers (5 3) in different directions to circle the band saw (8) and be fixed to the guide sleeve (1). The lower L-shaped frame (1 2) is adjusted with the lifting of the guide frame (1). The operation wheel set (6) is provided in the recess (7 3) of the earth machine base (7 1). Where appropriate, the operation wheel (6 1) protrudes from the end surface to facilitate the operation of the operator ❸, and the operation wheel (61) The gear (62) is connected inward, so that the gear (62) is engaged with the rack (4) passing through the groove (63), thereby driving the guide sleeve (1) to rise and fall. With the composition of the above components, please refer to the fifth figure to make the band saw (8

Page 6 2764 M243290 V. Creation instructions (4) *) The upper and lower transmission wheels (81) and (82) are wound around the upper and lower bases (7 1) and (7 6) at the same time, and The guide sleeve (1) and the guide wheel set (5) are passed through at the same time; at this time, the guide sleeve (1) and the movable cover (2) are located at the highest point, and the concave notch (1 6) can just accommodate the upload A part of the moving wheel (8 1) allows the band saw (8) to smoothly enter the guide sleeve (1), and the upper baffle (2 1) of the movable cover (2) will not generate with the upper transmission wheel (8 1). put one's oar in. If the operation wheel (6 1) is rotated to drive the gear (6 2) to forcibly drive the rack (4) together with the guide sleeve (1) to start to descend, the movable cover (2) also descends as shown in the sixth figure; when When descending to a certain degree, the movable cover (2) first hooks the upper edge of the guide block (3) with the upper baffle (2 1), and the guide sleeve (1) can continue to descend until this time. As shown in the seventh figure. Based on the composition and implementation of the above components, it can be known that this creation has the following advantages compared with conventional use, such as: 1 · The guide sleeve (1) of this creation is formed by stamping and folding a plate, and its processing and composition are far more conventional. The main sleeve is simple, which can reduce the cost effect. 02. The guide sleeve (1) of this creation is relatively thin and flat, and the bottom end forms a smaller volume segment (1 3), which will not occupy too much vision. Area, ... is very convenient and practical for processing operations during machine operation. 3 · The movable cover (2) with the guide block (3) is set at the notch (73) of the bottom plate (72) of the upper base (71), which not only guides better, but also the movable cover (2) There are obstacles on the top and bottom
