Description

Technical Field

[0001] The invention relates to the technical field of shoemaking, in particular to leather cutting equipment for shoemaking. Background Art

[0002] Leather is a denatured, non-perishable animal skin obtained through physical and chemical processes such as depilation and tanning. Leather is made of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster, and feels comfortable. In the current shoemaking process, leather needs to be cut, but some leather is soft. When cutting, the shape of the cut is irregular due to the softness of the leather, which affects the cutting and molding quality of the leather.

[0003] After searching, for example, the specification of patent publication number CN107488756B discloses the use of hot melt adhesive to form a hard shell on the leather surface. The hard shell ensures the stability of the leather shape during the cutting process and ensures the quality of leather cutting. Under the shaping effect of the hard shell, the cutting knife cuts the hard shell and the leather together. When cutting the leather, the leather changes from a soft state to a hard state, avoiding the irregular cutting effect caused by the soft leather.

[0004] However, in the above technical solution, the colloid is applied to the leather by a roller, which cannot effectively ensure the uniformity of the thickness of the rubber layer on the leather. At the same time, when the rubber cylinder is applied to the roller, the uniformity of the rubber layer on the roller cannot be guaranteed. When the leather is subsequently cut, due to the uneven thickness of the rubber layer, the cutting depth of the leather is different or part of the leather is not completely cut, which still affects the cutting and forming quality of the leather.

A pipe rack is also fixedly connected to branch one, and the pipe rack is sleeved on the vertical part of the conveying pipe.

[0010] As a further supplement to the present application, the anti-backflow assembly includes a slide cylinder, a backflow baffle and a spring.

[0014] By setting the glue leveling plate, the excess glue on the pressure roller can be scraped off, making the glue applied by the pressure roller more uniform. At the same time, the glue can be saved and the insufficient thickness of the glue layer can be compensated, thereby further improving the uniformity of the glue layer on the pressure roller.

[0015] By setting the scraper, the scraper can scrape off the residual colloid on the pressure roller to prevent the residual colloid at the bottom of the rubber layer on the pressure roller from solidifying and affecting the subsequent re-uniform application of the colloid on the pressure roller.

[0016] Through the setting of structures such as the sponge ring and the rotating drum, when the sponge ring rotates to the inside of the oil tank, it will absorb the oil. When the sponge ring continues to rotate and fits the pressure roller, the oil will be smeared on the pressure roller. As a result, when the leather passes through the pressure roller, the colloid can be effectively applied to the leather, minimizing the adhesion between the colloid and the pressure roller.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 13 , the present invention provides a technical solution: The present invention provides a leather cutting device for shoemaking, comprising a conveyor belt 1, a cutting piece 20, a pressure roller 15, a support 2 and a rubber cylinder 11, wherein the conveyor belt 1 is rotatably mounted between two supports 2, and leather 3 is laid on the conveyor belt 1, a connecting seat 23 is provided on one side of the support 2, the pressure roller 15 is rotatably mounted between the two connecting seats 23, and a retaining edge is provided at the edge of the side wall of the pressure roller 15, the rubber cylinder 11 is arranged above the pressure roller 15, and the lower part of the rubber cylinder 11 is a gradually deformed channel, which is generally wide at the top and narrow at the bottom. , so that the transition area at the connection between the lower glue port 112 and the rubber cylinder 11 can be increased, the flow rate difference can be reduced, and the uniform amount of glue can be ensured. At the same time, since the required amount of glue is small, the lower glue port 112 needs to be relatively narrow. The setting of the gradual deformation channel is also to reduce the colloid flow rate of the lower glue port 112 and save colloid. A bracket 5 is provided on one side of the connecting seat 23, and the rubber cylinder 11 is fixedly connected to the bracket 5. A push rod 114 is provided inside the rubber cylinder 11, and a partition 113 is fixedly connected to the lower end of the push rod 114. The partition 113 The two sides of the rubber cylinder 11 are respectively provided with pressing plates 115 for rotation, and one end of the pressing plate 115 away from the partition 113 is slidably fitted with the inner wall of the rubber cylinder 11, and the push rod 114 can push the pressing plate 115 to slide inside the rubber cylinder 11, providing appropriate pressure to ensure the uniformity of the glue flow rate and the uniformity of the flow rate of the glue at the lower glue port 112, so that the glue can be evenly distributed on the pressing roller 15, so that the glue on the pressing roller 15 is evenly applied on the leather 3 to form a glue layer with uniform thickness, so that the soft leather 3 can form a hard shell with uniform thickness, and when the leather 3 is cut later, it is avoided that the cutting depth of the leather 3 is different or part of the leather 3 is not completely cut due to the uneven thickness of the glue layer, which affects the quality of the leather 3. At the same time, if the thickness of the glue layer is uneven, the hardness of the shell will also be different. When the hardness does not meet the standard, the soft leather 3 will shrink during cutting. The two sides of the conveyor belt 1 are provided with frames 21, and the frames 21 are respectively equipped with cold air pipes 19, cutting pieces 20 and hot air pipes 22.

[0021] The upper end of the rubber cylinder 11 is provided with a cover body 12, and the cover body 12 is movably installed with the upper end of the rubber cylinder 11 by bolts 26, so that the cover body 12 and the rubber cylinder 11 can be disassembled, which is convenient for adding rubber into the rubber cylinder 11 later. A heating component can be set on the rubber cylinder 11 to prevent the hot melt adhesive from solidifying. The heating component is a conventional technical means in this field, so it is not repeated here. A top seat 14 is installed on the cover body 12, and a motor 27 is installed on the top seat 14. The output end of the motor 27 is fixedly connected with a threaded rod 13, and the end of the threaded rod 13 away from the motor 27 passes through the cover body 12 and extends to the inside of the rubber cylinder 11. The push rod 114 is threadedly connected with the threaded rod 13. When the motor 27 rotates, the threaded rod 13 can be driven to rotate. When the threaded rod 13 rotates, the push rod 114 can be pushed to move up and down inside the rubber cylinder 11. The use of threaded transmission can accurately control the moving speed of the push rod 114, and the transmission speed is relatively slow, which is suitable for controlling the uniform feeding of the rubber.

[0022] A groove 118 is provided at one end of the pressing plate 115 close to the partition 113, and a rotating shaft 116 is fixedly connected inside the groove 118. A connecting plate 119 is fixedly connected to the side wall of the partition 113. The rotating shaft 116 is rotatably connected to the connecting plate 119, and a torsion spring 117 is sleeved on the rotating shaft 116. The torsion spring 117 abuts between the partition 113 and the pressing plate 115. The side walls of the partition 113 on both sides are provided with arc-shaped rotating grooves 121, and the pressing plate 115 is provided with an arc-shaped rotating surface 120 that slidably cooperates with the arc-shaped rotating grooves 121. When the pressing plate 115 rotates around the rotating shaft 116, the arc-shaped rotating grooves 121 and the arc-shaped rotating surface 120 can always fit together, so as to avoid the colloid from being affected in the case of not affecting the rotation of the pressing plate 115. The pressure plate 115 is adjusted according to the width of the channel of the rubber cylinder 11, that is, when the push rod 114 drives the pressure plate 115 to move downward to push the rubber, when encountering the gradual channel below, the pressure plate 115 can rotate with the cooperation of the rotating shaft 116 and the torsion spring 117, and the two pressure plates 115 form a "V" shape, so that the edge of the pressure plate 115 can slide downward against the inner wall of the rubber cylinder 11 to push the rubber.

[0023] A glue leveling member 8 is provided on one side of the pressure roller 15. The glue leveling member 8 is a hollow groove body inside. A glue leveling plate 801 is provided on the side of the glue leveling member 8 close to the pressure roller 15. The setting of the glue leveling plate 801 can scrape off the excess glue on the pressure roller 15, so that the glue applied on the pressure roller 15 is more uniform and can save glue. A compensation plate 802 is provided on the other side of the glue leveling member 8, and the height of the compensation plate 802 is higher than the glue leveling plate 801. A heating component can also be provided on the glue leveling member 8. Since the height of the compensation plate 802 is higher than the glue leveling plate 8 01, so when the accumulation height of the colloid in the glue-leveling member 8 is higher than the highest position of the glue-leveling plate 801 and lower than the highest position of the compensation plate 802, the colloid will compensate for the insufficient thickness of the pressure roller 15, ensuring the uniform coating of the colloid on the pressure roller 15, and improving the uniformity of the subsequent glue layer formed on the leather 3. A transition box 25 is fixedly connected to one side of the glue-leveling member 8, and a delivery pipe 10 is fixedly connected to the interior of the transition box 25. The other end of the delivery pipe 10 is connected to the rubber cylinder 11, and a backflow prevention component is provided at the connection point. When the height of the colloid accumulated in the glue-leveling member 8 is higher than the highest position of the compensation plate 802, the colloid will enter the interior of the transition box 25, and then be transported to the interior of the rubber cylinder 11 through the delivery pipe 10. A heating component can also be provided on the outside of the delivery pipe 10.

[0024] A support plate 6 is fixedly connected between the support 2 and the connecting seat 23, and the support plate 6 includes a branch 1 601 and a branch 2 602. The branch 2 602 is fixedly connected to the side wall of the glue leveling member 8. A motor 24 is installed on the branch 1 601. An auger is rotatably installed inside the vertical part of the conveying pipe 10. One end of the auger passes through the transition box 25 and is fixedly connected to the output end of the motor 24. A feed trough 31 is provided on the side wall of one end of the conveying pipe 10 close to the transition box 25. The setting of the feed trough 31 facilitates the colloid to enter the interior of the conveying pipe 10. A pipe rack 9 is also fixedly connected to the branch 1 601. The pipe rack 9 is sleeved on the vertical part of the conveying pipe 10. When the motor 24 rotates, the auger is driven to rotate to convey the colloid inside the transition box 25 to the inside of the rubber cylinder 11.

[0025] The backflow prevention assembly includes a slide cylinder 33, a backflow baffle 7 and a spring 36. The backflow baffle 7 fits the inner wall of the rubber cylinder 11. The slide cylinder 33 is fixedly connected to one side of the backflow baffle 7. The slide cylinder 33 is slidably connected to the inside of the slide cylinder 33. A connecting rod 35 is fixedly connected to the inside of the delivery tube 10 close to the rubber cylinder 11. One end of the slide rod 34 is fixedly connected to the connecting rod 35, and a spring 36 is sleeved on the outside of the slide rod 34. The spring 36 is fixedly connected between the slide cylinder 33 and the connecting rod 35. When the colloid inside the delivery tube 10 reaches the backflow baffle 7 under the push of the auger, the backflow baffle 7 will be squeezed. The backflow baffle 7 drives the slide cylinder 33 to slide on the slide rod 34 and stretches the spring 36 at the same time. When the colloid inside the rubber cylinder 11 moves into the delivery tube 10, the backflow baffle 7 will be squeezed, so that the backflow baffle 7 is tightly fitted with the inner wall of the rubber cylinder 11 to prevent the colloid inside the rubber cylinder 11 from flowing into the delivery tube 10.

[0026] A scraper 4 is provided on the other side of the pressure roller 15, a scraper plate 401 is provided on the top of the scraper 4, a material box 402 is provided on the bottom of the scraper 4, the end of the scraper plate 401 is in contact with the pressure roller 15, the scraper plate 401 can scrape off the residual colloid on the pressure roller 15 to prevent the residual colloid at the bottom of the glue layer on the pressure roller 15 from solidifying and affecting the subsequent re-uniform application of the colloid on the pressure roller 15, a connecting frame 18 is fixedly connected to the frame 21, and one end of the connecting frame 18 close to the scraper 4 is fixedly connected to the scraper 4, and the material box 402 is used to receive the colloid scraped off by the scraper plate 401.

[0027] An oil groove 29 is fixedly connected to the upper end of the rubber scraper 4, and an oil tank 17 is fixedly connected to the top of the oil groove 29. The oil tank 17 is connected to the oil groove 29. A rotating drum 28 is rotatably arranged inside the oil groove 29. A sponge ring 16 is sleeved on the outside of the rotating drum 28. The sponge ring 16 is in contact with the outer wall of the pressure roller 15. A rotating frame 30 is fixedly connected to the rubber scraper 4. The rotating drum 28 is rotatably mounted on the rotating frame 30. An extrusion column 32 is provided below the rotating drum 28. The extrusion column 32 is rotatably mounted on the inner wall of the oil groove 29. The extrusion column 32 is in contact with the sponge ring 16. The edge height of one side of the oil groove 29 close to the pressure roller 15 is higher than the lowest position of the rotating drum 28. When the colloid is applied on the pressure roller 15, a part of it will adhere to the pressure roller 15, which will also cause uneven thickness of the leather 3. There is oil in the oil groove 29, and the rotating drum 28 follows the pressure roller. When the sponge ring 16 rotates to the inside of the oil groove 29, it will absorb the oil. When the sponge ring 16 that continues to rotate fits with the pressure roller 15, the oil will be smeared on the pressure roller 15, so that when the leather 3 passes through the pressure roller 15, the colloid can be effectively smeared on the leather 3, and the adhesion of the colloid to the pressure roller 15 is minimized. At the same time, when the sponge ring 16 rotates to the inside of the oil groove 29, the squeezing column 32 will squeeze the sponge ring 16, and squeeze out the gas inside the sponge ring 16, so that the sponge ring 16 can absorb the oil more effectively and quickly. If the sponge ring 16 is not squeezed by the squeezing column 32, there will be some air in addition to the residual oil in the sponge ring 16. When the sponge ring 16 enters the oil, the speed of absorbing the oil will be slow and the absorption will be insufficient, which affects the subsequent uniform oiling on the pressure roller 15.

[0028] Working principle: The leather 3 is spread out and laid flat on the conveyor belt 1, and the conveyor belt 1 is driven by a motor to transport the leather 3. When the conveyor belt 1 drives the leather 3 to move, the pressure roller 15 can be driven by the friction between the leather 3 and the pressure roller 15, or the pressure roller 15 can be driven by the motor to rotate. When the pressure roller 15 rotates and contacts the sponge ring 16, the oil on the sponge ring 16 will be smeared on the pressure roller 15. When the motor 27 rotates, the threaded rod 13 can be driven to rotate, and when the threaded rod 13 rotates, it can push the push rod 114 When the push rod 114 moves up and down inside the rubber cylinder 11 and drives the pressing plate 115 to move downward to push the colloid, when encountering the gradual change channel below, the pressing plate 115 can rotate under the cooperation of the rotating shaft 116 and the torsion spring 117, and the two pressing plates 115 form a "V" shape, so that the edge of the pressing plate 115 can slide downward against the inner wall of the rubber cylinder 11 to push the colloid, and always provide a certain pressure on the colloid, so that the colloid can flow out of the rubber cylinder 11 evenly, and thus be evenly smeared on the pressing roller 15; When the pressure roller 15 passes through the glue leveling member 8, the setting of the glue leveling plate 801 can scrape off the excess colloid on the pressure roller 15, so that the colloid applied on the pressure roller 15 is more uniform, and the excess colloid can be transported to the inside of the rubber cylinder 11 again through the conveying pipe 10. When the leather 3 passes between the pressure roller 15 and the conveyor belt 1, the leather 3 will be coated with colloid. When the pressure roller 15 passes through the glue scraping member 4, the glue scraping plate 401 can scrape off the residual colloid on the pressure roller 15 to prevent the residual colloid at the bottom of the glue layer on the pressure roller 15 from solidifying and affecting the subsequent re-uniform application of the colloid on the pressure roller 15. When the leather 3 continues to move forward on the conveyor belt 1 and reaches under the cold air pipe 19, the cold air is sprayed vertically toward the surface of the leather 3 through the nozzle of the cold air pipe 19, and the hot melt adhesive on the surface of the leather 3 hardens and takes shape quickly when it is cooled, forming a hard shell on the surface of the soft leather 3; the conveyor belt 1 continues to convey the leather 3 to the cutting piece 20 for cutting. When the conveyor belt 1 conveys the cut leather 3 to the hot air pipe 22, the hot air pipe 22 provides hot air, and the hot air is blown vertically toward the surface of the leather 3 through the nozzle of the hot air pipe 22. The hot melt adhesive on the surface of the leather 3 softens when it is heated, and the hot melt adhesive can be removed at this time.

[0029] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
