Description

Technical Field

[0001] This invention relates to the field of leather bag manufacturing and processing technology, and in particular to a leather bag manufacturing edge pressing device. Background Technology

[0002] Leather has a wide range of applications, such as leather sofas, leather chairs, and leather bags. When leather is processed into these items, it usually needs to go through a pressing process. Pressing is divided into cold pressing and hot pressing depending on the thickness and properties of different leathers. Pressing is to press a certain edge line according to the edge of the leather. The edge line pressed out of the leather edge is conducive to the subsequent sewing positioning of the leather and also plays a decorative role, making the leather objects more three-dimensional. If it is necessary to make decorative patterns on the surface of the leather, the pressing process can also be used to press certain patterns into specific positions on the leather to play a decorative role. For items like sofas and leather chairs, because their shapes are relatively regular, the edge-pressing mechanism usually moves along a straight line or remains stationary while other mechanisms assist in pulling the leather. However, for leather bags, because of the diverse shapes of bags, the cut leather is often irregular. Therefore, edge-pressing of leather bags currently relies heavily on manual labor. This results in low production efficiency, high skill requirements for the craftsmen, and variations in quality even among different craftsmen producing the same bag, leading to high production costs.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN212669724U, patent name: a leather electric heating edge presser) is as follows: the top of the base (1) is respectively equipped with an edge pressing seat (8) and a support column (3), a top seat (6) is fixed on one side of the support column (3), a linear motor (5) is installed on the top of the top seat (6), a piston rod (7) is connected to the output end of the linear motor (5), a hammer head (10) is threaded to the end of the piston rod (7), a limiting groove (15) is opened inside the edge pressing seat (8), a buffer plate (12) is slidably connected in the limiting groove (15) through a limiting rod (14), a spring (13) is installed at the bottom of the buffer plate (12) and the limiting rod (14), an edge pressing groove (11) is above the buffer plate (12), and a brake button (9) and a start button (16) are respectively installed on one side of the top of the edge pressing seat (8).

[0004] As can be seen from the above implementation scheme, the leather electric heating edge pressing device is set to press the leather edge with a hammer head. However, the hammer head only has the function of moving up and down. Therefore, when pressing the leather edge, the leather electric heating edge pressing device can only play an auxiliary role. How to press the edge according to the required edge still needs to be controlled by hand. Therefore, the use of the leather electric heating edge pressing device is quite limited. Summary of the Invention

[0005] This invention overcomes the shortcomings of existing technologies by setting up an edge pressing component and a conformal edge pressing component. The conformal edge pressing component can adjust the edge pressing parts according to the shape of the edge pressing, so that several edge pressing parts can be arranged into a corresponding edge pressing shape. Then, the edge pressing parts press the leather, and the edge pressing head of the edge pressing component presses the leather according to the set curve. The edge pressing head moves along the side of the shape formed by several edge pressing parts, realizing automatic edge pressing while ensuring that the leather does not shift during the edge pressing process.

The receiving component includes a receiving module, which is connected to a receiving lifting cylinder, which is connected to a receiving suction component.

[0026] A process for pressing the edges of leather used in bag manufacturing using an edge-pressing device includes the following steps:

[0027] A. Based on the shape of the edge line that needs to be pressed on the leather, make the shape of the conformal edge of the conformal block, and set the distance that each conformal block extends relative to the conformal base when pressing the leather, so that the shape of several conformal edges arranged and placed matches the shape of the edge line that needs to be pressed.

[0028] B. There are two methods for edge pressing of leather: cold pressing and hot pressing. In the cold pressing process, the leather needs to be sprayed with water first. After spraying with water, the edge pressing head without heating is used to press it according to the required edge shape. In the hot pressing process, the leather does not need to be sprayed with water first. The temperature of the edge pressing head is adjusted according to the temperature required for edge pressing of different leathers, and then the edge pressing head is used to press it according to the required edge shape.

[0029] C. According to the shape of the edge line that needs to be pressed on the leather, install the pressing head of a specific shape onto the lower end of the polygonal tube;

[0030] D. After the preparation work is completed, the operator places a whole stack of leather that needs to be pressed on the lifting plate of the raw material lifting platform. The lifting plate determines the lifting height according to the thickness of the stack of leather. Each time a piece of leather is taken away, the lifting plate will rise to the same height as the thickness of the leather, so that no matter how many pieces of leather are taken away, the height of the top piece of leather will always remain the same.

[0031] E. For leather that requires cold pressing, after the receiving suction unit picks up the top piece of leather, the feeding suction unit is raised by the power of the feeding lifting cylinder, so that the top piece of leather is separated from the bottom piece of leather. Then, driven by the feeding module, the feeding suction unit brings the leather to the humidification component. The feeding suction unit puts the leather down, and the nozzle moves while spraying and humidifying the leather under the drive of the nozzle moving module. After spraying is completed, the feeding suction unit continues to absorb the leather and brings the leather to the edge pressing component. After the leather is placed at the edge pressing component, the feeding suction unit returns to the raw material lifting platform to pick up another piece of leather.

[0032] F. For leather that requires hot pressing, after the receiving suction unit picks up the top piece of leather, the feeding suction unit is raised under the power of the feeding lifting cylinder, so that the top piece of leather is separated from the bottom piece of leather. Then, driven by the feeding module, the feeding suction unit brings the leather directly to the pressing component. After the leather is placed at the pressing component, the feeding suction unit returns to the raw material lifting platform to pick up another piece of leather.

[0033] G. Several conformal pressing components extend to the pressing assembly by different lengths under the drive of the conformal positioning motor. The pressing components are positioned at the corresponding angles under the drive of the pressing shape adjustment motor. At this time, the conformal edges of several conformal blocks are arranged to be consistent with the edge line that needs to be pressed.

[0034] H. The pressing cylinder drives the pressing block to press down, so that several conforming blocks press down along the side of the pressing edge line, and several conforming blocks press down the leather.

[0035] I. Driven by the circular moving motor, the circumferential moving motor and the swaying motor, the pressing head first moves to the starting point of the edge line of the leather pressing. Then, driven by the pressing lifting cylinder, it descends to press the leather. Then, the pressing head moves according to the pre-set pressing route to press the leather edge. If it is a cold pressing process, the pressing head does not need to be heated at this time. If it is a hot pressing process, the pressing head needs to be set with the pressing temperature according to the properties of the pressing leather.

[0036] J. After the edge pressing is completed, the edge pressing head is raised by the edge pressing lifting cylinder and no longer presses the leather. It moves to the side close to the transfer component. Then, the material receiving suction component of the transfer component is driven by the material receiving module to the edge pressing component. Then, the material receiving suction component is lowered by the material receiving lifting cylinder to suck up the leather that has been pressed. Then, the material receiving suction component rises and moves the leather to the material receiving component.

[0037] Compared with the prior art, the beneficial effects of this invention are that it sets up a pressing component and a conformal pressing component. The conformal pressing component can adjust the pressing parts according to the shape of the pressing part, so that several pressing parts can be arranged into a corresponding pressing shape. Then, the pressing parts press the leather, and the pressing head moves according to the set curve to press the leather. The pressing head moves along the side of the shape formed by several pressing parts, realizing automatic pressing while ensuring that the leather does not shift during the pressing process. A humidification component is also set up, so that the device can process not only hot-pressed leather but also cold-pressed leather, expanding the application range of the device. In addition, a raw material lifting platform, a transfer component, and a receiving component are also set up. The combination of these three components enables the equipment to automatically feed materials, change the processing position of the leather during processing, and automatically receive materials. Compared with traditional manual pressing and workpiece-assisted pressing, it realizes the automation of the pressing process and improves production efficiency. Attached Figure Description

Detailed Implementation

[0054] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0055] like Figures 1 to 14 As shown, a leather bag manufacturing edge-pressing device is used for cold or hot edge pressing of leather during the bag manufacturing process. In the process of making leather bags, the leather needs to undergo an edge-pressing process. Depending on the properties of the leather and the desired processing effect, cold or hot edge pressing is required. For cold edge pressing, the leather needs to be sprayed with water before pressing, and the edge-pressing head 3073 does not need to be heated; it can be kept at room temperature. For hot edge pressing, the leather does not need to be sprayed with water before pressing, but the edge-pressing head 3073 needs to be heated. After the edge-pressing head 3073 is heated, it is maintained at a certain temperature before pressing the leather. The heating temperature depends on the properties of the leather and the desired shaping effect. As such, this device includes a pressing assembly 3 and a conformal pressing assembly 6. The pressing assembly 3 includes a pressing head 3073, which can move and rotate on the horizontal plane of the pressing assembly 3. The pressing head 3073 can be raised and lowered within the internal space of the pressing assembly 3, and the temperature of the pressing head 3073 can be adjusted. The conformal pressing assembly 6 includes several pressing parts 607, which can move along the straight line of the conformal pressing assembly 6 and the pressing assembly 3. The pressing parts 607 can move up and down and rotate relative to the conformal pressing assembly 6. The pressing parts 607 include a pressing block 6071, which is detachably connected to a conformal block 6072. The conformal block 6072 is provided with a conformal edge 607G, which is set according to the shape of the pressing edge line. Therefore, when automatically pressing the leather edges, firstly, several pressing components 607 are arranged into a corresponding pressing shape. Then, the pressing components 607 press the leather, and the pressing head 3073 of the pressing assembly 3 moves according to a set curve to press the leather edges. The pressing head 3073 moves along the side of the shape formed by the several pressing components 607. Therefore, when the pressing head 3073 presses the leather edges, the leather is also pressed by the several pressing components 607, and the pressing position of the several pressing components 607 is very close to the moving position of the pressing head 3073. This makes the movement of the pressing head 3073 on the leather... The frictional force generated between the leather and the machine is not enough to move the leather, thus achieving automatic edge pressing while ensuring that the leather does not shift during the pressing process. The machine is also equipped with a humidification component 2, which enables it to process not only hot-pressed leather but also cold-pressed leather, expanding its application range. In addition, it is equipped with a raw material lifting platform 1, a transfer component 5, and a material receiving component 4. The combination of these three components enables the machine to automatically feed leather, change the processing position of the leather during processing, and automatically receive the material. Compared with traditional manual edge pressing and workpiece-assisted edge pressing, it realizes the automation of edge pressing process and improves production efficiency.

[0056] The pressing assembly 3 includes a pressing base 301, which includes a pressing mounting plate 3011. The pressing mounting plate 3011 is provided with a bearing groove 301A and a connecting rod groove 301B. The bearing groove 301A and the connecting rod groove 301B are connected. The width of the bearing groove 301A is greater than the width of the connecting rod groove 301B. A rod end movable bearing 304 is slidably connected in the bearing groove 301A. The rod end movable bearing 304 is connected to the movable bearing connecting shaft. 3041, the end of the movable bearing connecting shaft 3041 away from the rod end movable bearing 304 is connected to the annular movable rotating rod 303. Because the width of the bearing groove 301A is greater than the width of the connecting rod groove 301B, the rod end movable bearing 304 can be supported by the connection between the bearing groove 301A and the connecting rod groove 301B and will not fall off. The movable bearing connecting shaft 3041 can also pass through the connecting rod groove 301B to achieve connection with the annular movable rotating rod 303.

[0057] The pressing assembly 3 includes a pressing ring moving motor 302, which is connected to a ring moving rotating rod 303. Therefore, the ring moving rotating rod 303 can rotate with its shortest point of connection to the moving motor 302 as the center. Because the end of the ring moving rotating rod 303 furthest from the moving motor 302 is connected to the moving bearing connecting shaft 3041, the stability of the rotation of the ring moving rotating rod 303 is ensured. The ring moving rotating rod 303 is slidably connected to an ironing head swing component 306. 306 includes a sliding connecting seat 3061; the annular moving rod 303 is provided with a circumferential moving component 305, the circumferential moving component 305 includes a circumferential moving motor 3051, the circumferential moving motor 3051 is connected to a circumferential moving screw 3052, the circumferential moving screw 3052 is threadedly connected to the circumferential moving seat 3053, and the sliding connecting seat 3061 is connected to the circumferential moving seat 3053; therefore, the circumferential moving motor 3051 can drive the sliding connecting seat 3061 to slide on the annular moving rod 303.

[0058] The circumferential moving seat 3053 is connected to the swing motor 3054, the swing motor 3054 is connected to the first gear 3055, the swing rod 3062 is rotatably connected to the sliding connecting seat 3061, the swing rod 3062 is connected to the second gear 3063, and the first gear 3055 and the second gear 3063 are meshed. Therefore, the swing motor 3054 can drive the swing rod 3062 to rotate.

[0059] A number of balls 306A are rotatably connected to the sliding connecting seat 3061. The balls 306A are in rolling connection with the sliding groove of the annular moving rod 303 and the upper end face of the annular moving rod 303. The balls 306A reduce the resistance of the sliding connecting seat 3061 when the annular moving rod 303 moves, so that the sliding connecting seat 3061 moves smoothly when the annular moving rod 303 moves.

[0060] The pressing assembly 3 includes a pressing head swing mechanism 306 and a pressing mechanism 307. The pressing head swing mechanism 306 includes a swing rod 3062, and a first polygonal insert rod 3065 is provided at the lower end of the swing rod 3062. A lifting cylinder seat 3064 is provided between the swing rod 3062 and the first polygonal insert rod 3065. The pressing mechanism 307 includes a pressing lifting cylinder 3071, which is connected above the lifting cylinder seat 3064. The output end of the pressing lifting cylinder 3071 is connected to a polygonal insert tube 3072, and the upper end of the polygonal insert tube 3072 is movably inserted into the first polygonal insert rod 3065. Because it is a polygonal fitting connection, it ensures that the rotation angle of the swing rod 3062 can be transmitted to the first polygonal insert rod 3065 accordingly. The above transmission mechanism enables the pressing head 3073 to move, rotate, and lift within the semi-circular range enclosed by the bearing sliding groove 301A.

[0061] The pressing head 3073 is inserted into the lower end of the polygonal insertion tube 3072. The pressing head 3073 includes a second polygonal insertion rod 307A and a shaping pressing block 307B. The second polygonal insertion rod 307A is inserted into the lower end of the polygonal insertion tube 3072. Because it is a polygonal fitting connection, it ensures that the rotation angle of the polygonal insertion tube 3072 can be transmitted to the pressing head 3073 accordingly. The second polygonal insertion rod 307A and the polygonal insertion tube 3072 are connected by a fixing pin 3074. When changing different pressing heads 3073, simply pull out the fixing pin 3074, pull out the old pressing head 3073 from the lower end of the polygonal insertion tube 3072, insert the new pressing head 3073 from the lower end of the polygonal insertion tube 3072, and then insert the fixing pin 3074 to connect the two. This connection method makes the operation of changing the pressing head 3073 very simple and does not require the use of external tools, which is convenient and quick.

[0062] In this embodiment, both the polygonal insertion tube 3072 and the pressing head 3073 are made of brass. Brass has good thermal conductivity. The polygonal insertion tube 3072 is connected to an external heating wire, which can heat the polygonal insertion tube 3072. The temperature of the polygonal insertion tube 3072 and the pressing head 3073 can also be controlled by an external control device.

[0063] The 3073 edge clamp can be as follows: Figure 4 The pressing structure can also be a knurling structure with a knurling wheel. The pressing head 3073 moves along the leather and can press and emboss at the corresponding position on the edge or in the middle of the leather.

[0064] The conformal pressing assembly 6 includes a conformal base 601, on which a conformal sliding seat 602 is disposed. The conformal sliding seat 602 is connected to several conformal positioning motors 603. Several conformal pressing components 604 are slidably connected to the conformal sliding seat 602. One end of each conformal pressing component 604 is connected to a pressing power component 605 and a pressing shape adjustment mechanism 606. A pressing component 607 is connected to the pressing shape adjustment mechanism 606. The conformal pressing component 604 includes a sliding rod 6041, with a meshing space 604B in the middle. A rack 6042 is disposed within the meshing space 604B. The conformal positioning motors 603 and 6044 are connected to the conformal pressing components 604. 03 Connects the third gear 6031, which meshes with the rack 6042. Because the meshing space is located in the middle of the sliding rod 6041, and the sliding rod 6041 is slidably connected to the conformal sliding seat 602, the sliding rod 6041 is slidably inserted into the sliding hole of the conformal sliding seat 602, and the outer shape of the sliding rod 6041 matches the sliding hole. Therefore, the sliding hole limits the sliding rod 6041 to prevent it from swinging. Thus, the cooperation between the sliding hole and the sliding rod 6041 is equivalent to the cooperation between the slide rail and the slider. This design saves on the slide rail and slider, further saving on processing costs and the space occupied by the slider and slide rail.

[0065] The edge-pressing shape adjustment mechanism 606 is slidably connected to the conformal pressing component 604. The conformal pressing component 604 includes a pressing lifting space 604A. The edge-pressing shape adjustment mechanism 606 includes an edge-pressing lifting seat 6061. A spring sleeve rod 6062 is inserted into the pressing lifting space 604A. A first spring 6063 is inserted into the spring sleeve rod 6062. The edge-pressing lifting seat 6061 and the spring sleeve rod 6062 are slidably connected. The spring sleeve rod 6062 is located above the first spring 6063. The pressing power component 605 includes a pressing cylinder 6051. The output end of the pressing cylinder 6051 is connected to a pressing block 6052. The pressing block 6052 is located above the edge-pressing lifting seat 6061. This arrangement allows the pressing block 6052 to press the edge-pressing lifting seat 6061. The pressure at 61 is at its maximum, which maximizes the pressure transmitted from the pressing lifting seat 6061 to the pressing component 607. This ensures that the pressing component 607 can press the leather firmly when the pressing head 3073 presses the leather. When the pressing component 607 is not pressing the leather, the pressing lifting seat 6061 is at the upper end of the pressing lifting space 604A under the action of the first spring 6063. When the pressing component 607 needs to press the leather, the pressing cylinder 6051 drives the pressing block 6052 to press down. The pressing block 6052 presses down the pressing lifting seat 6061, causing the pressing lifting seat 6061 to move to the lower end of the pressing lifting space 604A. At this time, the pressing component 607 also descends, thus enabling the pressing component 607 to press the leather.

[0066] The pressing edge lifting seat 6061 is connected to the pressing edge shape adjusting motor 6064. The pressing edge component 607 is connected to the pressing edge shape adjusting motor 6064. The pressing edge shape adjusting motor 6064 can make the pressing edge component 607 rotate at a set angle. When the conforming edges 607G of several conforming blocks 6072 can change to different curves by rotation, and these curves can match the pressing edge line, when changing the leather pressing edge, it is not necessary to replace the conforming blocks 6072. It is only necessary to make the pressing edge component 607 rotate a certain angle by the pressing edge shape adjusting motor 6064, so that several conforming blocks 6072 can change to a new edge line combination shape.

[0067] When the device is changed, the shape and size of the edge to be pressed are significantly different. If rotating the pressing part 607 cannot meet the new edge pressing requirements, then the conformal block 6072 needs to be replaced.

[0068] The pressure block 6071 is provided with a first slot 607B and a second slot 607C that are perpendicular to each other. One end of the first slot 607B is open, and the other end is provided with a first slot stop 607A. One end of the second slot 607C is open, and the other end is provided with a second slot stop 607D. Limiting spring holes 607E are provided on both sides of the second slot 607C. A second spring 6073 is connected inside the limiting spring hole 607E. The second spring 6073 is connected to a limiting post 6074. The limiting post 6074... The conformal block 6072 is movably connected to the limiting spring hole 607E; a first insert 607H is provided on the conformal block 6072, which is movably inserted into the first slot 607B; a limiting block 6075 is movably inserted into the second slot 607C; a second insert 607F is provided on the limiting block 6075, and the length of the second insert 607F is shorter than the length of the limiting block 6075; the second insert 607F is movably inserted into the second slot 607C; when replacing the conformal block 6072, the limiting post 607B is moved away from the limiting spring hole 607E. 74 is pressed into the limiting spring hole 607E so that the limiting post 6074 does not block the direction of the limiting block 6075's retraction. Then, the limiting block 6075 is moved away from the square shape of the conformal block 6072 until the limiting block 6075 no longer blocks the opening of the first slot 607B. Then, the conformal block 6072 is removed from the first slot 607B, and a new conformal block 6072 is inserted into the first slot 607B. Finally, the limiting block 6075 is moved towards the square shape of the conformal block 6072 until... When the limit stop 6075 blocks the opening of the first slot 607B, the limit post 6074 protrudes from the limit spring hole 607E under the elastic force of the second spring 6073, thus blocking the limit stop 6075. The end of the limit stop 6075 away from the limit spring hole 607E is blocked by the second slot stop 607D and will not come out. Therefore, the stability of the connection between the pressure block 6071 and the conformal block 6072 is guaranteed. This connection method is quick and convenient and does not require other tools for disassembly and assembly.

[0069] A humidifying component 2 is provided at one end of the pressing component 3, a receiving component 4 is provided at the end of the pressing component 3 away from the humidifying component 2, a raw material lifting platform 1 is provided at the end of the humidifying component 2 away from the pressing component 3, and a transfer component 5 is provided on the same side of the raw material lifting platform 1, the humidifying component 2, the pressing component 3, and the receiving component 4. The transfer component 5 is located between the pressing component 3 and the conformal pressing component 4.

[0070] The raw material lifting platform 1 includes a material trough 101, which is connected to a raw material lifting motor 102 and a lifting bearing 105. The raw material lifting motor 102 is connected to a lifting screw 103, and the lifting bearing 105 is connected to a lifting support rod 106. Both the lifting bearing 105 and the lifting support rod 106 are connected to a seated bearing 107 at their upper ends, and the seated bearing 107 is connected to a lifting plate 104. The operator places a whole stack of leather that needs to be pressed on the lifting plate 104 of the raw material lifting platform 1. The lifting plate 104 determines the lifting height according to the thickness of the stack of leather. Each time a piece of leather is removed, the lifting plate 104 will rise to the same height as the thickness of the leather, so that no matter how many pieces of leather are removed, the height of the top piece of leather remains consistent. This ensures that the feeding adsorption component 5023 can pick up the top piece of leather each time it picks up leather. The stability of the leather position ensures the stability of the feeding adsorption component 5023 in picking up materials, and ensures that the device can operate normally and stably.

[0071] The transfer assembly 5 includes a transfer mounting base 501, on which a feeding component 502 and a receiving component 503 are connected. The feeding component 502 includes a feeding module 5021, which is connected to a feeding lifting cylinder 5022. The feeding lifting cylinder 5022 is connected to a feeding suction component 5023. The receiving component 503 includes a receiving module 5031, which is connected to a receiving lifting cylinder 5032. The receiving lifting cylinder 5032 is connected to a receiving suction component 5033. The feeding component 502 and the receiving component 503 operate separately, which further improves the production efficiency of the device and saves production time.

[0072] Humidification component 2 includes a humidification base 201, with a nozzle moving module 202 mounted on the upper end of the humidification base 201. Nozzle moving rails 203 are mounted on both sides of the nozzle moving module 202. Both the nozzle moving module 202 and the nozzle moving rails 203 are connected to a nozzle mounting base 204. The nozzle mounting base 204 has at least one nozzle 205. For leather requiring cold pressing, after the receiving suction component 5033 picks up the topmost piece of leather, the feeding suction component 5023 is raised under the power of the feeding lifting cylinder 5022, causing the topmost piece of leather to... The leather piece is separated from the leather underneath. Then, driven by the feeding module 5021, the feeding adsorption component 5023 brings the leather to the humidification component 2. The feeding adsorption component 5023 puts the leather down, and the nozzle 205 moves while spraying and humidifying the leather under the drive of the nozzle moving module 202. After spraying is completed, the feeding adsorption component 5023 continues to adsorb the leather and brings it to the edge pressing component 3. After the leather is placed in the edge pressing component 3, the feeding adsorption component 5023 returns to the raw material lifting platform 1 to pick up another piece of leather.

[0073] For leather that requires hot pressing, after the receiving suction unit 5033 picks up the top piece of leather, the feeding suction unit 5023 is raised under the power of the feeding lifting cylinder 5022, so that the top piece of leather is separated from the bottom piece of leather. Then, driven by the feeding module 5021, the feeding suction unit 5023 directly brings the leather to the edge pressing component 3. After the leather is placed at the edge pressing component 3, the feeding suction unit 5023 returns to the raw material lifting platform 1 to pick up another piece of leather.

[0074] Driven by the conformal positioning motor 603, several conformal pressing components 604 extend to the pressing component 3 by different lengths. The pressing component 607 is positioned at the corresponding angle under the drive of the pressing shape adjustment motor 6064. At this time, the conformal edges 607G of several conformal blocks 6072 are arranged to be consistent with the edge line to be pressed.

[0075] The pressing cylinder 6051 drives the pressing block 6052 to press down, causing several conforming blocks 6072 to press down along the side of the pressing edge line, and several conforming blocks 6072 press down the leather.

[0076] Driven by the pressing ring moving motor 302, the circumferential moving motor 3051, and the swing motor 3054, the pressing head 3073 first moves to the starting point of the edge line of the leather pressing. Then, driven by the pressing lifting cylinder 3071, it descends to press the leather. Then, the pressing head 3073 moves according to the pre-set pressing route to press the leather edge. If it is a cold pressing process, the pressing head 3073 does not need to be heated. If it is a hot pressing process, the pressing head 3073 needs to set the pressing temperature according to the properties of the pressing leather.

[0077] After the edge pressing is completed, the edge pressing head 3073 is raised by the edge pressing lifting cylinder 3071 and no longer presses the leather. It moves to the side close to the transfer component 5. Then, the material receiving suction member 5033 of the transfer component 5 is driven by the material receiving module 5031 to the edge pressing component 3. Then, the material receiving suction member 5033 is lowered by the material receiving lifting cylinder 5032 to suck up the leather that has been pressed. Then, the material receiving suction member 5033 rises and moves the leather to the material receiving component 4.

[0078] The structure of the receiving component 4 is the same as that of the raw material lifting platform 1. Each time the pressed leather is received, the receiving platform will drop to a height equivalent to the thickness of the leather. This ensures that the receiving adsorption component 5033 can be placed down at the same height each time, thus ensuring the orderly stacking of finished products and facilitating the work of the next process.

[0079] A process for pressing the edges of leather used in bag manufacturing using an edge-pressing device includes the following steps:

[0080] A. Based on the shape of the edge line that needs to be pressed on the leather, make the shape of the conformal edge 607G of the conformal block 6072, and set the distance that each conformal block 6072 extends relative to the conformal base 601 when pressing the leather, so that the shape of several conformal edges 607G after being arranged and placed matches the shape of the edge line that needs to be pressed.

[0081] B. There are two methods for edge pressing of leather: cold pressing and hot pressing. In the cold pressing process, the leather needs to be sprayed with water first. After spraying with water, the edge pressing head 3073 without heating is used to press the leather according to the required edge shape. In the hot pressing process, the leather does not need to be sprayed with water first. The temperature of the edge pressing head 3073 is adjusted according to the temperature required for edge pressing of different leathers. Then, the edge pressing head 3073 is used to press the leather according to the required edge shape.

[0082] C. According to the shape of the edge line that needs to be pressed on the leather, install the pressing head 3073 of a specific shape onto the lower end of the polygonal insert 3072.

[0083] D. After the preparation work is completed, the operator places a whole stack of leather that needs to be pressed on the lifting plate 104 of the raw material lifting platform 1. The lifting plate 104 determines the lifting height according to the thickness of the stack of leather. Each time a piece of leather is taken away, the lifting plate 104 will rise to the same height as the thickness of the leather, so that no matter how many pieces of leather are taken away, the height of the top piece of leather will always remain the same.

[0084] E. For leather that needs to be cold-pressed, after the receiving adsorption component 5033 picks up the top piece of leather, the feeding adsorption component 5023 is raised under the power of the feeding lifting cylinder 5022, so that the top piece of leather is separated from the bottom piece of leather. Then, driven by the feeding module 5021, the feeding adsorption component 5023 brings the leather to the humidification component 2. The feeding adsorption component 5023 puts the leather down, and the nozzle 205 moves while spraying and humidifying the leather under the drive of the nozzle moving module 202. After the spraying is completed, the feeding adsorption component 5023 continues to adsorb the leather and brings the leather to the pressing component 3. After the leather is placed in the pressing component 3, the feeding adsorption component 5023 returns to the raw material lifting platform 1 to pick up another piece of leather.

[0085] F. For leather that requires hot pressing, after the receiving suction unit 5033 picks up the top piece of leather, the feeding suction unit 5023 is raised under the power of the feeding lifting cylinder 5022, so that the top piece of leather is separated from the bottom piece of leather. Then, driven by the feeding module 5021, the feeding suction unit 5023 directly brings the leather to the pressing component 3. After the leather is placed at the pressing component 3, the feeding suction unit 5023 returns to the raw material lifting platform 1 to pick up another piece of leather.

[0086] G. Several conformal pressing components 604 extend to the pressing assembly 3 by different lengths under the drive of conformal positioning motor 603. The pressing component 607 is positioned at the corresponding angle under the drive of pressing shape adjustment motor 6064. At this time, the conformal edges 607G of several conformal blocks 6072 are arranged in a shape consistent with the edge line to be pressed.

[0087] H. Pressing cylinder 6051 drives pressing block 6052 to press down, so that several conforming blocks 6072 press down along the side of the pressing edge line, and several conforming blocks 6072 press down the leather.

[0088] I. Under the joint drive of the pressing ring moving motor 302, the circumferential moving motor 3051 and the swing motor 3054, the pressing head 3073 first moves to the starting point of the edge line of the leather pressing, and then descends to press the leather under the drive of the pressing lifting cylinder 3071. Then the pressing head 3073 moves according to the pressing route set beforehand to press the leather edge. If it is a cold pressing process, the pressing head 3073 does not need to be heated at this time. If it is a hot pressing process, the pressing head 3073 needs to set the pressing temperature according to the properties of the pressing leather.

[0089] J. After the pressing is completed, the pressing head 3073 is raised by the pressing lifting cylinder 3071 and no longer presses the leather. It moves to the side close to the transfer component 5. Then, the receiving suction member 5033 of the transfer component 5 is driven by the receiving module 5031 to the pressing component 3. Then, the receiving suction member 5033 is lowered by the receiving lifting cylinder 5032 to suck up the leather that has been pressed. Then, the receiving suction member 5033 rises and moves the leather to the receiving component 4.

[0090] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

Each time a piece of leather is taken away, the lifting plate (104) will rise to the same height as the thickness of the leather, so that no matter how many pieces of leather are taken away, the height of the top piece of leather will always remain the same. E. For leather that needs to be cold-pressed, after the receiving adsorption unit (5033) picks up the top piece of leather, the loading adsorption unit (5023) is raised under the power of the loading lifting cylinder (5022), so that the top piece of leather is separated from the bottom piece of leather. Then, under the drive of the loading module (5021), the loading adsorption unit (5023) brings the leather to the humidification component (2). The loading adsorption unit (5023) puts the leather down, and the nozzle (205) moves while spraying and humidifying the leather under the drive of the nozzle moving module (202). After the spraying is completed, the loading adsorption unit (5023) continues to adsorb the leather and brings the leather to the pressing component (3). After the leather is placed at the pressing component (3), the loading adsorption unit (5023) returns to the raw material lifting platform (1) to pick up another piece of leather. F. For leather that requires hot pressing, after the receiving suction unit (5033) picks up the top piece of leather, the feeding suction unit (5023) is raised under the power of the feeding lifting cylinder (5022), so that the top piece of leather is separated from the bottom piece of leather. Then, under the drive of the feeding module (5021), the feeding suction unit (5023) brings the leather directly to the pressing component (3). After the leather is placed at the pressing component (3), the feeding suction unit (5023) returns to the raw material lifting platform (1) to pick up another piece of leather. G. Several conformal pressing components (604) extend to the pressing assembly (3) by different lengths under the drive of the conformal positioning motor (603). The pressing component (607) is positioned at the corresponding angle under the drive of the pressing shape adjustment motor (6064). At this time, the conformal edges (607G) of several conformal blocks (6072) are arranged in a shape consistent with the edge line to be pressed. H. The pressing cylinder (6051) drives the pressing block (6052) to press down, so that several conforming blocks (6072) press down along the side of the pressing edge line, and several conforming blocks (6072) press down the leather. I. Under the joint drive of the pressing ring moving motor (302), the circumferential moving motor (3051) and the swing motor (3054), the pressing head (3073) first moves to the starting point of the edge line of the leather pressing, and then descends to press the leather under the drive of the pressing lifting cylinder (3071). Then the pressing head (3073) moves according to the pressing route set beforehand to press the leather edge. If it is a cold pressing process, the pressing head (3073) does not need to be heated at this time. If it is a hot pressing process, the pressing head (3073) needs to set the pressing temperature according to the properties of the pressing leather. J. After the pressing is completed, the pressing head (3073) is raised by the pressing lifting cylinder (3071) and no longer presses the leather. It moves to the side close to the transfer assembly (5). Then the receiving suction unit (5033) of the transfer assembly (5) is driven by the receiving module (5031) to the pressing assembly (3). Then the receiving suction unit (5033) is driven by the receiving lifting cylinder (5032) to lower and suck up the leather that has been pressed. Then the receiving suction unit (5033) rises and moves the leather to the receiving assembly (4).
