Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, specifically to an automatic gluing, edge-separating, and pressing device for leather strip drawing. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing, such as hair removal and tanning, to become deformed and less prone to decay. Leather is composed of naturally woven protein fibers in a three-dimensional space, and its surface has a special grain layer, giving it a natural grain and luster, and a comfortable feel.

[0003] Before leather products are manufactured, the leather needs to be stripped. After stripping, in order to ensure the smoothness of the edges and increase the service life of the edges, the edges are usually processed, such as applying glue, so that the strips can be fixed to the edges of the leather strips later. However, now the edge splitting and gluing are done separately, which affects the processing efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an automatic gluing and edge-separating device for leather strip drawing, which uses the friction energy of the rubber ring to pull the leather strip outward, so that the leather strip can complete the sanding and gluing operations in one go, thereby solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: an automatic gluing and edge-separating pressing device for leather strip drawing, comprising a base plate, a panel, a polishing mechanism, a gluing mechanism, a pressing mechanism, and multiple leather strips to be processed. The panel and the base plate are arranged parallel to each other. The polishing mechanism, the gluing mechanism, and the pressing mechanism are distributed sequentially from left to right. The leather strips pass through the polishing mechanism and the gluing mechanism in sequence, and are conveyed by the pressing mechanism. Multiple support columns are installed between the panel and the base plate. A cylinder is installed on the side of the panel facing the base plate. The piston rod of the cylinder passes through the panel and is fixedly connected to the polishing mechanism.

[0006] As a preferred technical solution, the polishing mechanism includes an adjusting plate, multiple first fixed plates, multiple first drive rollers, and polishing rings. The adjusting plate is disposed on the panel and fixedly connected to the piston rod of the cylinder. The first fixed plates are distributed in pairs, with one end of each first fixed plate mounted on the adjusting plate. The first drive rollers are disposed between each pair of first fixed plates. A first bearing is embedded in each first fixed plate at the roller shaft opposite to the drive roller. The roller shafts on the first drive rollers are all mounted in the inner ring of the first bearings. The polishing rings are all mounted on the first drive rollers, and a polishing channel is formed between adjacent polishing rings. Leather strips are disposed in the polishing channel and are in frictional contact with the side of the polishing ring.

[0007] As a preferred technical solution, the grinding mechanism also includes a first motor, a synchronous belt and multiple synchronous pulleys. The roller shaft at one end of the first drive roller extends outward and is fixedly connected to the synchronous pulley. The synchronous belt is installed on the synchronous pulley. The rotating shaft of the first motor is fixedly connected to the roller shaft of any one of the first drive rollers. A motor base is installed between the first motor and the adjusting plate.

[0008] As a preferred technical solution, the gluing mechanism includes a second drive roller, a second motor, a material box, and multiple gluing rings. The material box is mounted on the panel, a portion of the second drive roller extends into the material box, and multiple gluing rings are mounted on the second drive roller, forming gluing channels between the gluing rings. The sides of the leather strips are all in contact with the sides of the gluing rings, and a portion of each gluing ring extends into the material box. Both ends of the material box protrude to form fixing parts, and second bearings are embedded in the fixing parts. The roller shafts on the second drive roller are all mounted in the inner rings of the second bearings. A second motor is mounted on one side of the fixing part, and the shaft of the second motor is fixedly connected to the roller shaft on the second drive roller.

[0009] As a preferred technical solution, the pressing strip driving mechanism includes a second motor, multiple second fixed plates, multiple third drive rollers, and gears. The second fixed plates are all mounted on the panel. The third drive rollers are arranged parallel to each other between the second fixed plates, one above the other. Multiple rubber rings are mounted on each third drive roller. The outer rings of the rubber rings are respectively in frictional contact with the upper and lower surfaces of the leather strip. Third bearings are embedded in each of the second fixed plates opposite to the third drive rollers. The roller shafts at both ends of the third drive rollers are mounted in the inner rings of the third bearings. Gears are mounted on the roller shafts of the third drive rollers and are meshed with each other. The second motor is mounted on one side of the third fixed plate and is fixedly connected to the roller shafts on the third drive rollers.

[0010] As a preferred technical solution, the width of the rubber rings is smaller than the width of the leather strips, and the rubber rings are not in contact with the two side edges of the leather strips.

[0011] As a preferred technical solution, the panel is provided with multiple positioning holes at the position opposite the adjustment plate. The multiple positioning holes are evenly distributed in a rectangular structure. Positioning rods are installed on one side of the panel at the position opposite the positioning holes, and the positioning rods are set through the positioning holes.

[0012] As a preferred technical solution, multiple glue inlet holes are formed by recesses on both sides of the glue ring.

[0013] The beneficial effects of this utility model are as follows: This utility model has a simple structure. The leather strip is pressed by a rubber ring and pulled outward through friction, allowing the leather strip to pass through the polishing channel and the gluing channel in one go. The rotating polishing ring polishes the edges on both sides of the leather strip to ensure smoothness, while the gluing ring carries the glue in the material box and applies it to the edges on both sides of the leather strip. Since the width of the rubber ring is smaller than that of the leather strip, the glue on the edges will not come into contact during the conveying process, ensuring the quality of subsequent processing. Moreover, the above is completed in one go, increasing efficiency. Attached Figure Description

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an automatic gluing and edge-separating pressing device for leather strip drawing, comprising a base plate 1, a panel 2, a polishing mechanism, a gluing mechanism, a pressing mechanism, and multiple leather strips 8 to be processed. The panel 2 is arranged parallel to the base plate 1. The polishing mechanism, the gluing mechanism, and the pressing mechanism are distributed from left to right. The leather strips 8 pass through the polishing mechanism and the gluing mechanism in sequence, and are conveyed by the pressing mechanism. Multiple support columns 18 are installed between the panel 2 and the base plate 1. A cylinder 20 is installed on the side of the panel 2 facing the base plate 1. The piston rod of the cylinder 20 passes through the panel 2 and is fixedly connected to the polishing mechanism.

[0024] In this embodiment, the polishing mechanism includes an adjusting plate 3, multiple first fixed plates 17, multiple first drive rollers 21, and polishing rings 6. The adjusting plate 3 is disposed on the panel 2 and is fixedly connected to the piston rod of the cylinder 20. The first fixed plates 17 are distributed in pairs, with one end of each first fixed plate 17 mounted on the adjusting plate 3. The first drive rollers 21 are disposed between each pair of first fixed plates 17. A first bearing is embedded in each first fixed plate 17 at the roller shaft opposite to the drive roller. The roller shafts on the first drive rollers 21 are all mounted in the inner ring of the first bearing. The polishing rings 6 are all mounted on the first drive rollers 21. A polishing channel is formed between adjacent polishing rings 6. The leather strips 8 are all disposed in the polishing channel and are in frictional contact with the side of the polishing rings 6.

[0025] In this embodiment, the grinding mechanism also includes a first motor 7, a synchronous belt 5 and multiple synchronous pulleys 4. The roller shaft at one end of the first drive roller 21 extends outward and is fixedly connected to the synchronous pulley 4. The synchronous belt 5 is installed on the synchronous pulley 4. The rotating shaft of the first motor 7 is fixedly connected to the roller shaft of any one of the first drive rollers 21. A motor base is installed between the first motor 7 and the adjusting plate 3.

[0026] In this embodiment, the gluing mechanism includes a second drive roller 10, a second motor 12, a material box 9, and multiple gluing rings 11. The material box 9 is mounted on the panel 2. A portion of the second drive roller 10 extends into the material box 9. Multiple gluing rings 11 are mounted on the second drive roller 10, and gluing channels are formed between the gluing rings 11. The sides of the leather strips 8 are in contact with the sides of the gluing rings 11. A portion of the gluing rings 11 extends into the material box 9. Both ends of the material box 9 protrude to form fixing parts. Second bearings are embedded in the fixing parts. The roller shafts on the second drive roller 10 are mounted in the inner rings of the second bearings. A second motor 12 is mounted on one side of the fixing part, and the rotating shaft of the second motor 12 is fixedly connected to the roller shaft on the second drive roller 10.

[0027] In this embodiment, the pressing strip driving mechanism includes a second motor 12, multiple second fixing plates 13, multiple third driving rollers 22, and gears 14. The second fixing plates 13 are all mounted on the panel 2. The third driving rollers 22 are arranged parallel to each other between the second fixing plates 13. Multiple rubber rings 15 are mounted on each of the third driving rollers 22. The outer ring surface of the rubber rings 15 is respectively in frictional contact with the upper and lower surfaces of the leather strip 8. The second fixing plates 13 are each embedded with a third bearing at the position opposite to the third driving roller 22. The roller shafts at both ends of the third driving roller 22 are all mounted in the inner ring of the third bearing. The gears 14 are all mounted on the roller shafts of the third driving roller 22 and are meshed with each other. The second motor 12 is mounted on one side of the third fixing plate and is fixedly connected to the roller shafts on the third driving roller 22.

[0028] In this embodiment, the width of the rubber rings 15 is smaller than the width of the leather strip 8, and the rubber rings 15 are not in contact with the two side edges of the leather strip 8. The pressure and friction generated by the upper and lower rubber rings are greater than the friction between the grinding channel and the glue application channel and the leather strip, so that the leather strip can be smoothly conveyed. Since the width of the rubber rings is smaller than the width of the leather strip, they do not come into contact with the glue on the edge of the leather strip during the conveying process.

[0029] In this embodiment, the panel 2 is provided with multiple positioning holes facing the adjustment plate 3. The multiple positioning holes are evenly distributed in a rectangular structure. A positioning rod 19 is installed on one side of the panel 2 facing the positioning hole. The positioning rod 19 passes through the positioning hole and can position the adjustment plate so that the adjustment plate can only move up and down along the positioning hole.

[0030] The polishing ring is made of a polishing disc, and both sides of the polishing ring have polishing surfaces, so that the edges of both sides of the leather strip can be polished simultaneously.

[0031] The adjustment plate can be moved up and down by extending and retracting the piston rod on the cylinder. The movement of the adjustment plate drives the first fixed plate and the first drive roller, which in turn drives the polishing ring. This allows the contact position between the polishing ring and the leather strip to be adjusted to ensure the full utilization of the polishing ring.

[0032] In this embodiment, multiple glue inlet holes are formed on both sides of the glue ring 11, allowing glue to enter into the glue inlet holes, enabling the glue ring to carry more glue and better complete the glue application operation.

[0033] In use, the leather strips discharged from the strip drawing machine can enter the polishing channel and the gluing channel laterally until they enter between the rubber rings. After the third motor is started, the third motor can drive the gears, causing the two gears to rotate in opposite directions, and simultaneously drive the third drive roller to rotate in opposite directions. The rotation of the third drive roller drives the rubber ring, and the friction between the rubber ring and the leather strip can pull the leather strip outward, allowing the leather strip to pass smoothly through the polishing channel and the gluing channel.

[0034] During the above processing, the first motor and the second motor need to be started. The start of the first motor drives the synchronous pulley and the synchronous belt, so that the first drive roller can rotate synchronously. The rotation of the first drive roller drives the polishing ring. The friction between the polishing ring and the edge of the leather strip can polish it to ensure the smoothness of the edge.

[0035] In this process, glue is poured into the material box, and the glue-applying ring is partially submerged inside the material box. As the second motor starts, it drives the second drive roller and the glue-applying ring. The glue-applying ring lifts up the glue and applies it to the edges of both sides of the leather strip to complete the glue application. The pressing and driving mechanism can complete the sanding and glue application of the leather strip in one go, greatly increasing convenience.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
