Description

Technical Field

[0001] The invention relates to the technical field of leather conveying, and in particular to a positioning conveying device and method for leather processing. Background Art

[0002] During the leather processing and cutting process, the conveying device is used in conjunction with the photoelectric sensor to transport the leather to the appropriate position, ensuring that the cutting device can accurately cut the leather. After cutting, the leather and waste are transported to the next processing step, thus achieving continuous and accurate positioning and transportation of the leather, ensuring that the cutting work can be carried out uninterruptedly.

[0003] During the conveying process, leather will have some wrinkles and curling edges due to its own characteristics. This will not only affect the smoothness of the conveying of the leather, causing it to get stuck on the conveyor belt and disrupt the normal conveying rhythm, but also make it difficult for the photoelectric sensor to accurately identify the edge and position information of the leather, thereby affecting the accuracy of cutting and producing leather products or waste of unqualified sizes. In addition, when the wrinkled and curled leather is subsequently connected to other processing equipment, it cannot smoothly enter the processing position of the next process, thereby reducing the production efficiency of the entire leather processing production line and increasing the frequency and cost of manual intervention. Operators are required to frequently stop the production line to sort the leather, disrupting the originally efficient automated continuous production process.

[0004] Therefore, it is necessary to provide a positioning and conveying device and method for leather processing, aiming to solve the above problems. Summary of the invention

[0007] As a further improvement of the above solution, the installation assembly also includes an adjustment rod rotatably connected to the inside of the movable seat, the bottom of the adjustment rod is threadedly connected to the inside of the device base, and a connecting block is symmetrically fixedly connected between the two movable seats.

[0008] As a further improvement of the above scheme, the flattening assembly includes a smoothing roller and a fixed rod, the interior of the movable seat is slidably connected to a sliding seat, the smoothing roller is rotatably connected to the outside of the fixed rod, both ends of the fixed rod are slidably connected to the interior of the sliding seat, and a spring 2 is fixedly connected between the fixed rod and the inner wall of the sliding seat.

[0009] As a further improvement of the above scheme, the ironing assembly also includes a pressing belt, two driving shafts and two guide shafts are rotatably connected between the two movable seats, and a belt drive connection is formed between the pressing belt, the two driving shafts and the two guide shafts.

[0010] As a further improvement of the above scheme, the driving assembly includes a worm 1 rotatably connected to a movable seat, a worm 2 and a motor 2 are rotatably connected to the outer wall of the device base, the bottom of the worm 2 is fixedly connected to the output shaft of the motor 2 through a coupling, a worm wheel 1 is fixedly connected to the outer side of the driving shaft, a worm wheel 2 is fixedly connected to the outer side of the driving roller, the worm 1 and worm wheel 1 are meshed with each other, the worm 2 and worm wheel 2 are meshed with each other, the top of the worm 2 is fixedly connected to a connecting rod, and the worm 1 is slidably connected to the outer side of the connecting rod.

[0011] As a further improvement of the above solution, a torsion spring is fixedly connected between the connecting shaft and the slider, and a convex strip is arranged on the top of the smoothing strip.

[0012] As a further improvement of the above solution, the outer side wall of the slide seat is symmetrically fixedly connected to a limit block, and a spring 1 is fixedly connected between the slide seat and the inner wall of the movable seat.

[0013] As a further improvement of the above solution, a condensation plate is fixedly connected to the interior of the heating water tank, and a water inlet pipe is fixedly connected to the outer wall of the heating water tank.

[0014] The positioning and conveying method for leather processing comprises the following steps: Step 1: Place the leather in the device base and place it on one end of the conveyor belt, turn the adjustment rod in the movable seat, and adjust the height of the movable seat through the threaded connection between the movable seat and the device base; Step 2: Start the motor 1, and drive the screw rod to rotate through the installation shaft, so that the slider slides. The smoothing strip on the slider rotates through the meshing of the connecting shaft, gear and rack. The rotating smoothing strip acts on the bottom of the leather through the convex strip on the top to smooth the wrinkles. Step 3: Start the second motor to drive the second worm to rotate, and drive the driving roller meshing with the second worm to make the conveyor belt run to transport the leather. When the leather is transported to the bottom of the smoothing roller and encounters wrinkles and bulges, the smoothing roller is pushed to rotate and the wrinkles and bulges are smoothed. The fixed rod slides in the slide seat and compresses the second spring for buffering. The first spring and the limit block between the slide seat and the movable seat provide further buffering. Step 4: The rotation of worm 2 drives worm 1 and worm wheel 1 through the connecting rod, thereby driving the pressing belt to operate. The leather enters between the pressing belt and the conveyor belt, is stretched and fixed, and is conveyed to the bottom of the ironing seat. The steam from the heating water tank is sprayed out from the air holes of the ironing seat through connecting pipes 1 and 2 to iron the leather. After ironing, the pressing belt and the conveyor belt continue to squeeze the leather and convey it.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The leather is smoothed with the help of the smoothing component and the pushing component, and then enters between the pressing belt and the conveyor belt to be stretched and fixed, ensuring that the leather passes smoothly through the bottom of the ironing seat. The steam acts on the surface of the leather through the ironing seat to complete the ironing. Then the leather is squeezed and transported by the pressing belt and the conveyor belt to further consolidate the ironing effect, ensure that the leather is transported in a flatter state, and improve the cutting quality, eliminating human intervention, making leather processing and transportation more efficient and stable.

[0016] 2. The leather is placed in the base of the device, with one end naturally placed on the conveyor belt. Start motor 1, and the screw drives the smoothing strip to move and rotate synchronously. The bottom of the leather is smoothed by the convex blocks to reduce the wrinkles of the leather. Then the two smoothing strips are inclined, and the inclined convex blocks form a barrier in the inclined direction, so that the wrinkled parts of the leather transmitted by the conveyor belt are extended toward both ends and smoothed, ensuring the overall flat feeding and transportation of the leather.

[0017] 3. The conveyor belt drives the leather into the bottom of the smoothing roller, and the wrinkles on the leather push the smoothing roller to rotate. The smoothing roller rotates to push the leather to both ends to achieve further smoothing and ensure the smoothing effect. During the smoothing operation, spring 2 and spring 1 provide buffer space to prevent the leather from getting stuck at the bottom of the smoothing roller due to wrinkles that are difficult to smooth, effectively reducing the risk of leather damage.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0023] In practical application, the embodiment of the present invention is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, first, the leather is placed in the device base 1, one end of which is placed on the conveyor belt 31, and the motor 54 is started. Its output shaft drives the installation shaft 53 to rotate through the coupling, thereby causing the screw rod 55 symmetrically fixed on the outside of the installation shaft 53 to rotate synchronously. Since a spiral pair transmission is formed between the screw rod 55 and the slider 56 slidably connected to the top of the support seat 2, the rotation of the screw rod 55 causes the slider 56 to slide in a specific direction. The smoothing bar 51 rotatably connected to the top of the slider 56, with the help of the connecting shaft 57 fixedly connected inside and fixed to the smoothing bar 51 and The meshing transmission between the gear 58 fixed on the outside of the connecting shaft 57 and the rack 52 fixed on the top of the support seat 2 realizes the rotation of the smoothing strip 51 during the movement. During this process, the smoothing strip 51 with the convex structure smoothes the bottom of the leather to reduce the probability of leather wrinkles. Subsequently, the two smoothing strips 51 are in an inclined state. With the help of the blocking effect of the inclined convex in the inclined direction, the wrinkled part of the leather transmitted by the conveyor belt 31 is extended toward both ends, thereby further smoothing the leather and ensuring that the leather as a whole can be smoothly fed and conveyed. like Figures 1 to 5 As shown, as the conveyor belt 31 continues to operate, the leather is conveyed to the area where the ironing component 6 is located, and the heating water tank 61 heats the internal water. The generated steam passes through the connecting pipe 1 67 that is evenly fixed and connected to the top, and the connecting pipe 2 68 that is slidably connected to it and fixed to the top of the ironing seat 64, and finally sprays out from the air holes evenly opened at the bottom of the ironing seat 64, acts on the leather surface, and realizes the leather ironing operation. During this process, the supporting platform 65 fixedly connected inside the device base 1 provides stable support for the ironing operation, ensuring the smooth progress of the ironing process, so that the entire positioning and conveying device can efficiently and accurately complete the leather smoothing and ironing processing procedures, and provide flat and high-quality leather for subsequent leather processing.

[0024] like Figures 1 to 4 As shown, the mounting assembly 4 also includes an adjusting rod 42 rotatably connected to the inside of the movable seat 41 , the bottom of the adjusting rod 42 is threadedly connected to the inside of the device base 1 , and a connecting block 43 is symmetrically fixedly connected between the two movable seats 41 .

[0025] In actual application of the embodiment of the present invention, when it is necessary to fine-tune the height of the components installed between the movable seats 41, the adjusting rod 42 is rotated. Since its bottom is connected to the internal thread of the device base 1, as the adjusting rod 42 is rotated, the movable seat 41 will slide up or down relatively on the top of the device base 1, thereby achieving precise position adjustment to meet the processing requirements of leather of different thicknesses or ensure the precise coordination between related components and other device structures.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the flattening assembly 7 includes a smoothing roller 71 and a fixed rod 75. The interior of the movable seat 41 is slidably connected to a slide seat 72. The smoothing roller 71 is rotatably connected to the outside of the fixed rod 75. Both ends of the fixed rod 75 are slidably connected to the inside of the slide seat 72. A spring 2 76 is fixedly connected between the fixed rod 75 and the inner wall of the slide seat 72. The outer wall of the slide seat 72 is symmetrically fixedly connected to a limit block 74. A spring 1 73 is fixedly connected between the slide seat 72 and the inner wall of the movable seat 41.

[0027] In actual application of the embodiment of the present invention, when the leather is conveyed along the conveyor belt 31 and enters the bottom of the smoothing roller 71 of the flattening assembly 7, if there are wrinkles on the leather, the wrinkled protrusions will contact the smoothing roller 71 and push it to rotate. Since the smoothing roller 71 is rotatably connected to the outside of the fixing rod 75, and the two ends of the fixing rod 75 are slidably connected to the inside of the slide seat 72 and connected to the inner wall of the slide seat 72 through the second spring 76, when the leather pushes the smoothing roller 71 to rotate, the fixing rod 75 can slide relatively in the slide seat 72 and compress the second spring 76. The second spring 76 provides a certain buffer space, so that the smoothing roller 71 can better adapt to the surface of the leather. The uneven condition ensures that it can effectively push the leather wrinkles to both ends to achieve further smoothing. At the same time, the slide 72 is fixedly connected to the inner wall of the movable seat 41 by a spring 73, and the limit blocks 74 symmetrically fixed on the outer wall of the slide 72 can limit the sliding range of the slide 72. When the leather has a large impact force on the smoothing roller 71 or the smoothing roller 71 is unevenly stressed due to severe wrinkles, the spring 73 can further absorb and buffer this impact force to prevent the smoothing roller 71 from being damaged due to excessive force or being stuck at the bottom due to the difficulty in smoothing the leather wrinkles, thereby ensuring the stable operation of the flattening component 7 and improving the stability and reliability of leather processing.

[0028] like Figure 4 and Figure 5 As shown, the ironing assembly 6 also includes a pressing belt 631, two driving shafts 632 and two guide shafts 66 are rotatably connected between the two movable seats 41, and a belt transmission connection is formed between the pressing belt 631, the two driving shafts 632 and the two guide shafts 66; In actual application of the embodiment of the present invention, when the leather enters between the pressing belt 631 and the conveyor belt 31 under the transportation of the conveyor belt 31, the two driving shafts 632 start to rotate under the drive of the driving component 8, and drive the pressing belt 631 to operate synchronously. The pressing belt 631 applies a certain pressure to the leather, so that it can be stretched and fixed in cooperation with the conveyor belt 31. After ironing, the leather continues to move forward under the squeezing and transportation of the pressing belt 631 and the conveyor belt 31. The continuous pressure of the pressing belt 631 further consolidates the ironing effect, so that the leather remains flat for subsequent transportation.

[0029] like Figure 1 , Fig. 9 and Fig.10 As shown, the driving assembly 8 includes a worm 81 rotatably connected to the movable seat 41, a worm 82 and a motor 83 rotatably connected to the outer wall of the device base 1, the bottom of the worm 82 is fixedly connected to the output shaft of the motor 83 through a coupling, a worm wheel 84 is fixedly connected to the outer side of the driving shaft 632, and a worm wheel 85 is fixedly connected to the outer side of the driving roller 32. The worm 81 and the worm wheel 84 are meshed with each other, and the worm 82 and the worm wheel 85 are meshed with each other. The top of the worm 82 is fixedly connected to a connecting rod 86, and the worm 81 is slidably connected to the outer side of the connecting rod 86.

[0030] In actual application of the embodiment of the present invention, after the second motor 83 is started, its output shaft drives the second worm 82 to rotate. Since the second worm 82 is meshed with the second worm wheel 85 fixed on the outer side of the driving roller 32, the rotation of the second worm 82 drives the second worm wheel 85 and the driving roller 32 connected thereto to rotate, thereby driving the conveyor belt 31 to run, thereby realizing the stable transmission of leather on the conveyor belt 31. At the same time, the connecting rod 86 fixed on the top of the worm gear 82 forms a sliding connection with the worm gear 81 rotatably connected to the movable seat 41, and the worm gear 81 is meshed with the worm wheel 84 fixed on the outside of the drive shaft 632. When the worm gear 82 rotates, the worm gear 81 is driven to rotate through the linkage of the connecting rod 86, thereby driving the worm wheel 84 and the drive shaft 632 to operate, so that the pressing belt 631 rotates synchronously with the conveyor belt 31 under the drive of the drive shaft 632, completing the extrusion and transportation of the leather, and ensuring the safety and stability of the leather processing process.

[0031] like Figure 8 As shown, a torsion spring 59 is fixedly connected between the connecting shaft 57 and the slider 56 , and a convex strip is provided on the top of the smoothing strip 51 .

[0032] In actual application of the embodiment of the present invention, the torsion spring 59 can drive the smoothing strip 51 to rotate and reset, and the convex strip can better smooth the leather.

[0033] like Figure 3As shown, a condensation plate 62 is fixedly connected to the interior of the heating water tank 61, and a water inlet pipe is fixedly connected to the outer wall of the heating water tank 61.

[0034] In actual application of the embodiment of the present invention, the moisture in the steam can be reduced through the condensation plate 62 to prevent excessive moisture from affecting the ironing effect of the leather, and water for ironing can be added through the water inlet pipe.

[0035] The present invention provides another embodiment: A positioning and conveying method for leather processing is now proposed, comprising the following steps: Step 1: Place the leather in the device base 1 and put it on one end of the conveyor belt 31, rotate the adjustment rod 42 in the movable seat 41, and adjust the height of the movable seat 41 through the threaded connection between the adjustment rod 42 and the device base 1; Step 2: Start the motor 1 54, drive the screw 55 to rotate through the installation shaft 53, and make the slider 56 slide. The smoothing strip 51 on the slider 56 rotates through the meshing of the connecting shaft 57, the gear 58 and the rack 52. The rotating smoothing strip 51 acts on the bottom of the leather through the convex strip on the top to smooth the wrinkles. Step 3: Start the second motor 83 to drive the second worm 82 to rotate, and drive the driving roller 32 meshing with the second worm gear 85 to make the conveyor belt 31 run to convey the leather. When the leather is conveyed to the bottom of the smoothing roller 71 and encounters wrinkles and protrusions, the smoothing roller 71 is pushed to rotate and the wrinkles and protrusions are smoothed. Among them, the fixed rod 75 slides in the slide seat 72 and compresses the second spring 76 for buffering. The spring 1 73 and the limit block 74 between the slide seat 72 and the movable seat 41 further buffer. Step 4: The worm gear 2 82 rotates to drive the worm gear 1 81 and the worm wheel 1 84 through the connecting rod 86, thereby driving the pressing belt 631 to operate. The leather enters between the pressing belt 631 and the conveyor belt 31, is stretched and fixed, and is conveyed to the bottom of the ironing seat 64. The steam from the heating water tank 61 is sprayed out from the air holes of the ironing seat 64 through the connecting pipe 1 67 and the connecting pipe 2 68 to iron the leather. After ironing, the pressing belt 631 and the conveyor belt 31 continue to squeeze the leather and convey it.
