Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, specifically to a leather peeling machine for shoe production. Background Technology

[0002] In the process of shoe making, leather is often used as the material for the upper and sole. The thickness and quality of the leather raw material directly affect the texture and comfort of the shoe. Therefore, before shoe production, the leather needs to be peeled to meet the required thickness and quality standards. A special leather peeling machine is a device specifically used to adjust the thickness and shape of the leather edges.

[0003] Chinese utility model patent CN215162836U discloses a leather peeling machine for shoe production. This device is equipped with a guide box, a dust treatment device, and a blower box. By activating the suction fan, dust can be sucked up during peeling. At the same time, the guide box is fixedly connected to the dust treatment device through a ventilation pipe, so that the dust can be sent into the dust treatment device. The dust can be filtered by the dust filter screen at the top of the filter sleeve. The dust can also fall naturally due to gravity and be collected by the dust collection box, which avoids dust flying around during operation and being easily inhaled by the human body, thus avoiding the impact on human health.

[0004] In existing technologies, the width of the leather being cut is adjusted by changing the diameter of the cutting equipment or the peeling device. However, changing the equipment or the peeling device wastes a lot of work efficiency and greatly increases the time required for sample or small-batch production. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes the following technical solution:

[0006] A leather peeling machine for shoe production includes a housing. A side support plate is fixedly installed on one side of the housing, and a main motor is fixedly installed inside the housing. The side support plate and the main motor are arranged opposite to each other on the housing. A main shaft is fixedly installed on the output shaft of the main motor. A rotating cutter cylinder is threadedly connected to the main shaft. A cutting blade is provided at the end of the rotating cutter cylinder away from the main motor. A side support cylinder is fixedly installed on the side support plate, and the axis of the side support cylinder is aligned with the axis of the rotating cutter cylinder. A sliding frame is slidably installed on the side support plate, and a placement plate is slidably installed on the sliding frame. A predetermined gap is left between the placement plate and the outer wall of the side support cylinder, and a predetermined gap is also left between the placement plate and the outer wall of the rotating cutter cylinder. The placement plate is slidably connected to the housing. A plurality of arc-shaped grooves are also provided on the side support plate, and the arc-shaped grooves are symmetrically arranged on the side support plate and located outside the side support cylinder. A small bracket is also fixedly installed on the placement plate, and a sliding wheel is rotatably installed on the small bracket. The sliding wheel is located within the arc-shaped groove.

[0007] Furthermore, a bottom bracket is fixedly installed on the side support plate. The bottom bracket is located between the side support cylinder and the rotating cutter cylinder. A belt shaft is rotatably installed on the bottom bracket. A main gear is fixedly installed at one end of the belt shaft. A secondary gear is meshed on the main gear. A rubber roller is fixedly installed on the secondary gear. The rubber roller is rotatably connected to the bottom bracket and is located between the side support cylinder and the rotating cutter cylinder.

[0008] Furthermore, a main support is rotatably mounted on the main shaft, and the main support is fixedly connected to the inner wall of the outer casing. A main bevel gear is also fixedly mounted on the main shaft, and multiple secondary bevel gears are meshed on the main bevel gear. The secondary bevel gears are rotatably connected to the main support, and a belt is also provided on the secondary bevel gears. The other end of the belt is provided on the belt shaft. After the main shaft rotates, the belt shaft can be driven to rotate through the main bevel gear, secondary bevel gears, and belt. Then, the belt shaft drives the rubber roller to rotate through the main gear and secondary gears. In this way, the rubber roller can drive the leather to move towards the cutter on the rotary cutter cylinder when the rotary cutter cylinder rotates, thereby completing the cutting.

[0009] Furthermore, a pressure plate frame is rotatably mounted on the outer shell, and a pressing torsion spring is provided on the pressure plate frame. The other end of the pressing torsion spring is fixedly mounted on the outer shell. An arc-shaped pressure plate is fixedly mounted on the pressure plate frame, and the arc-shaped pressure plate can contact the placement plate. A pressure plate handle is also fixedly mounted on the pressure plate frame.

[0010] The advantages of this utility model compared with the prior art are: (1) This device can adjust the width of leather cutting by moving the placement plate, thereby increasing the applicable range of this device and improving the efficiency of small batch production; (2) This device can press the leather by pressing the torsion spring on the pressure plate frame and then pressing the leather by the arc-shaped pressure plate, thereby allowing the leather to be completely cut by the rotating blade, ensuring the stability of the leather cutting thickness.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] like Figure 1 and Figure 2As shown, a leather peeling machine for shoe production includes a housing 101. A side support plate 109 is fixedly installed on one side of the housing 101. A main motor 201 is also fixedly installed inside the housing 101. The side support plate 109 and the main motor 201 are arranged opposite to each other on the housing 101. A main shaft 205 is fixedly installed on the output shaft of the main motor 201. A rotating cutter cylinder 207 is threadedly connected to the main shaft 205. A cutting blade is provided at the end of the rotating cutter cylinder 207 away from the main motor 201. A fixed cylinder 206 is also fixedly installed on the housing 101. The fixed cylinder 206 is rotatably connected to the main shaft 205.

[0019] like Figures 2 to 5 As shown, a lead screw handle 108 is rotatably mounted on the side support plate 109, and a side support cylinder 209 is fixedly mounted on the side support plate 109. The axis of the side support cylinder 209 is aligned with the axis of the rotating cutter cylinder 207. A sliding frame 107 is slidably mounted on the side support plate 109, and the sliding frame 107 is threadedly connected to the lead screw handle 108. A placement plate 106 is slidably mounted on the sliding frame 107. The placement plate 106 has a predetermined gap with the outer wall of the side support cylinder 209 and also a predetermined gap with the outer wall of the rotating cutter cylinder 207. The placement plate 106 is slidably connected to the outer shell 101. The end of the placement plate 106 away from the side support cylinder 209 has a predetermined space with the inner side of the outer shell 101. This space is used to provide space for the placement plate 106. The side support plate 109, which has a sliding space, is also provided with multiple arc-shaped grooves. The arc-shaped grooves are symmetrically arranged on the side support plate 109 and are located on the outside of the side support cylinder 209. A small bracket 110 is fixedly installed on the placement plate 106. A sliding wheel 111 is rotatably installed on the small bracket 110 and is located in the arc-shaped groove. When the sliding frame 107 slides on the side support plate 109, the sliding frame 107 will drive the placement plate 106 to move together. The sliding wheel 111 on the placement plate 106 will drive the placement plate 106 to slide on the sliding frame 107 according to the shape of the arc-shaped groove. In this way, the gap between the placement plate 106 and the side support cylinder 209 and the rotating cutter cylinder 207 can be maintained even after the height of the placement plate 106 changes.

[0020] like Figures 1 to 5As shown, a bottom bracket 305 is also fixedly installed on the side support plate 109. The bottom bracket 305 is located between the side support cylinder 209 and the rotating cutter cylinder 207. A belt shaft 302 is rotatably installed on the bottom bracket 305. A main gear 303 is fixedly installed at one end of the belt shaft 302. A secondary gear 304 is meshed on the main gear 303. A rubber roller 208 is fixedly installed on the secondary gear 304. The rubber roller 208 is rotatably connected to the bottom bracket 305. The rubber roller 208 is located between the side support cylinder 209 and the rotating cutter cylinder 207. The rubber roller 208 is used to drive the leather to move.

[0021] like Figures 2 to 5 As shown, a main support 202 is rotatably mounted on the main shaft 205. The main support 202 is fixedly connected to the inner wall of the outer casing 101. A main bevel gear 204 is also fixedly mounted on the main shaft 205. Multiple secondary bevel gears 203 are meshed on the main bevel gear 204. The secondary bevel gears 203 are rotatably connected to the main support 202. A belt 301 is also provided on the secondary bevel gears 203. The other end of the belt 301 is provided on the belt shaft 302. After the main shaft 205 rotates, the belt shaft 302 can be driven to rotate through the main bevel gear 204, secondary bevel gears 203, and belt 301. Then, the belt shaft 302 drives the rubber roller 208 to rotate through the main gear 303 and secondary gear 304. In this way, the rubber roller 208 can drive the leather to move towards the cutter on the rotating cutter cylinder 207 when the rotating cutter cylinder 207 rotates, thereby completing the cutting.

[0022] like Figures 2 to 5 As shown, a pressure plate frame 104 is rotatably mounted on the outer casing 101. A pressing torsion spring is provided on the pressure plate frame 104, and the other end of the pressing torsion spring is fixedly mounted on the outer casing 101. An arc-shaped pressure plate 103 for pressing leather is fixedly mounted on the pressure plate frame 104. The arc-shaped pressure plate 103 can contact the placement plate 106. The arc-shaped pressure plate 103 is located outside the side support cylinder 209, the rubber roller 208, and the rotary cutter cylinder 207. When the leather is on the rubber roller 208, it will also be pressed by the arc-shaped pressure plate 103. The arc-shaped pressure plate 103 holds the leather so that it passes through the cutting edge of the rotary cutter cylinder 207. A pressure plate handle 105 is also fixedly mounted on the pressure plate frame 104. By manually pulling the pressure plate handle 105 to rotate, the arc-shaped pressure plate 103 can be moved away from the rotary cutter cylinder 207 and the rubber roller 208, thus allowing the leather to be placed in.

[0023] Working Principle: In use, this invention works by pulling the pressure plate handle 105 to open the arc-shaped pressure plate 103, then placing the leather on the placement plate 106 and the side support cylinder 209. The arc-shaped pressure plate 103 then holds the leather in place. At this time, the main motor 201 is started, driving the rubber roller 208 and the rotating blade cylinder 207 to rotate. The rotation of the rubber roller 208 drives the leather to move from the side support plate 109 towards the rotating blade cylinder 207, and the rotation of the rotating blade cylinder 207 causes the cutting blades on the rotating blade cylinder 207 to cut the passing leather. The leather is peeled and thinned. When it is necessary to increase the peeling and thinning area, the lead screw handle 108 can be manually turned to move the placement plate 106. The placement plate 106 moves closer to the axis of the side support cylinder 209. At this time, the sliding wheel 111 will adjust the gap between the placement plate 106 and the side support cylinder 209 by squeezing through the arc groove. After the placement plate 106 moves downward, the arc length of the rotary cutter cylinder 207 on the placement plate 106 will increase, thereby increasing the length of leather cutting.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
