Description

Technical Field

[0002] With the continuous development of current technology, the automotive interior industry has also been continuously developing and progressing. Generally, an automotive seat cover is set on a seat and then fixed by a fixing strip of the automotive seat cover. The fixing strip of the automotive seat cover can be a relatively long strip produced from raw materials through processes such as melting, die extrusion, and cooling, and then cut into fixing strips of various required lengths according to the required specifications. After cutting, subsequent operations such as painting and stacking and packing are performed on the cut semi-finished strip. However, in the prior art, after cutting a long strip, the cut semi-finished strips are placed in a disorderly manner, which is not convenient for subsequent operations such as painting and stacking and packing. Usually, it is necessary to manually arrange the semi-finished strips in an orderly manner, but when manually arranging the strips in an orderly manner, not only is the labor intensity high, but also the work efficiency is low.

[0030] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present disclosure.

[0031] As Figures 1 to 9 shown, a processing device for a fixing strip of an automobile seat cover includes a bottom plate 1. A cutting table 2 is fixed on the bottom plate 1. An alignment mechanism is connected to one side of the cutting table 2. The alignment mechanism includes a pair of symmetric mounting plates 31. The mounting plates 31 are fixed on the bottom plate 1. A pair of vertically upwardly placed support plates 32 are fixed on the mounting plates 31. The upper ends of the two support plates 32 on the same mounting plate 31 are fixedly connected by a connecting rod 321. A fixing plate 33 is fixedly connected to the bottom plate 1. A rotating motor 34 is installed on the fixing plate 33. The output end of the rotating motor 34 is connected to a first rotating shaft 341. The first rotating shaft 341 is vertically placed with respect to the support plate 32. The first rotating shaft 341 passes through the fixing plate 33 and is rotatably connected to the fixing plate 33. A rotating rod 35 coaxially placed is fixedly connected to the first rotating shaft 341. The rotating rod 35 sequentially passes through each support plate 32 and is rotatably connected to the support plate 32. A pair of symmetrically placed runners 36 are fixedly sleeved on the rotating rod 35. The two runners 36 are located between the two support plates 32 on different mounting plates 31 that are close to each other. A plurality of evenly distributed grooves 361 are formed on each of the runners 36. The positions of the grooves 361 on the two runners 36 are always the same. Slide rail grooves 322 are formed on the support plates 32 close to the runners 36. The slide rail grooves 322 and the grooves 361 correspond to the movement trajectory from the side of the cutting table 2 along the upper part of the rotating rod 35 to the side away from the cutting table 2. The height of the cutting table 2 is higher than the height of the alignment mechanism. The side of the cutting table 2 close to the alignment mechanism is a downwardly concave arc table surface. The table surface at the end of the cutting table 2 away from the alignment mechanism is a flat table surface parallel to the bottom plate 1. A pair of baffles 4 are provided on the table surface of the cutting table 2. The baffles 4 are all in contact with the table surface of the cutting table 2. The baffles 4 are all fixedly connected to the support plates 32 on the side of the mounting plate 31 away from the runner 36. A plurality of feeding holes 41 are formed on the baffle 4 at the end away from the rotating motor 34;

[0032] This device is used in conjunction with a conveying mechanism in the prior art, such as a conveyor belt mechanism, a conveyor belt mechanism, etc. The conveying mechanism is connected to the side of the alignment mechanism away from the cutting table 2. Multiple long product strips produced through processes such as melting, die extrusion, and cooling pass through the feeding hole 41 and are placed on the cutting table 2. They are cut according to the required length, and the cut product strips are pushed out and slide along the arc table surface to be close to the alignment mechanism. Then, the rotation motor 34 is turned on. The rotation motor 34 drives the first rotating shaft 341, the first rotating shaft 341 drives the rotating rod 35, the rotating rod 35 drives the rotating wheel 36, and the rotating wheel 36 drives the groove 361. When the groove 361 rotates from the bottom up to the side close to the arc table surface, under the action of gravity, one of the multiple cut product strips on the arc table surface close to the groove 361 enters the groove 361. Driven by the two rotating wheels 36, the product strip moves along the slide rail groove 322, so that the product strip rotates smoothly to the side away from the cutting table 2 and is discharged onto the conveying mechanism. At the same time, the conveying mechanism is turned on to convey the product strip. Through the rotation of the rotating wheel 36 and the groove 361, each time a cut product strip is discharged and enters the conveying mechanism. By repeating the operation multiple times, the purpose of orderly discharging the cut product strips and placing them neatly on the conveying mechanism can be achieved, solving the problems in the prior art that when manually arranging the strips in an orderly manner, the labor intensity is high and the work efficiency is low, and facilitating subsequent operation processes such as painting, stacking, and boxing.

[0033] To facilitate the discharge of the product strip from the groove 361 into the conveying mechanism, through holes 362 are provided in the groove 361. The axes of the through holes 362 all face the center of the rotating wheel 36. A first spring 363 is coaxially fixed in the through hole 362. When the product strip enters the groove 361, during the process of the groove 361 rotating from above the axis of the rotating rod 35 to the conveying mechanism end through the cutting table 2 end, under the action of the gravity of the product strip, the first spring 363 is compressed, enabling the product strip to enter the groove 361 and pass through the slide rail groove 322. When the rotating wheel 36 drives the product strip to rotate to the conveying mechanism end, at this time, the through hole 362 in the groove 361 is in a horizontal state, and the gravity of the product strip will no longer act on the first spring 363. The first spring 363 pops out and pushes the strip to break away from the groove 361 and enter the conveying mechanism, achieving the purpose of facilitating the discharge of the product strip from the groove 361 into the conveying mechanism.

[0034] In order to facilitate the cutting of multiple long product card strips placed on the cutting table 2, a connecting plate 5 is fixedly connected to the upper end surface of the baffle 4 away from the end of the sorting mechanism. A hanging block 6 is provided at a position near the upper end of the connecting plate 5 away from the side of the rotating motor 34. The hanging block 6 is fixedly connected to the side surface of the connecting plate 5 near the side of the rotating motor 34. A first telescopic cylinder 61 is provided at the lower end of the hanging block 6. The bottom of the first telescopic cylinder 61 is fixedly connected to the lower end surface of the hanging block 6. The telescopic rod of the first telescopic cylinder 61 is fixedly connected with a cutting tool 62. Multiple long product card strips are placed on the cutting table 2 through the feeding hole 41, so that one end of the long product card strip is in pressing contact with the baffle 4 near the side of the rotating motor 34. Then, the first telescopic cylinder 61 is started, and the first telescopic cylinder 61 extends to drive the cutting tool 62 to move downward. The cutting tool 62 moves downward to cut the product card strip on the cutting table 2, achieving the purpose of facilitating the cutting of multiple long product card strips placed on the cutting table 2.

[0035] In order to adapt to the cutting and sorting of product card strips with various different length requirements, the mounting plate 31 away from the side of the rotating motor 34 in the mounting plate 31 is provided with a sliding connection with the bottom plate 1. A plurality of uniformly distributed first protrusions 351 are fixed on the circumferential side wall of the rotating rod 35. The first protrusions 351 are all arranged coaxially with the rotating rod 35. A sleeve 37 is provided between the runner 36 away from the side of the rotating motor 34 and the rotating rod 35. A plurality of uniformly distributed first clamping grooves 371 are formed on the inner side wall of the sleeve 37. The first clamping grooves 371 correspond to the first protrusions 351 one by one. The sleeve 37 is fixedly connected with the runner 36 away from the side of the rotating motor 34. The sleeve 37 is connected with the support plate 32 near the runner 36 through a rolling bearing 38. The rolling bearing 38 is fixedly installed on the support plate 32 near the runner 36. The rolling bearing 38 is arranged coaxially with the sleeve 37. The sleeve 37 passes through the rolling bearing 38 and is fixedly connected with the inner side wall of the inner ring of the rolling bearing 38. Move the mounting plate 31 away from the side of the rotating motor 34. The mounting plate 31 drives a pair of support plates 32 fixedly connected to the upper end. The support plates 32 drive the rolling bearing 38. The rolling bearing 38 drives the sleeve 37. The sleeve 37 drives the runner 36 away from the side of the rotating motor 34 to slide along the first protrusion 351. At the same time, the support plate 32 on the mounting plate 31 away from the side of the runner 36 drives the baffle 4. The baffle 4 away from the side of the rotating motor 34 moves to drive the connecting plate 5 fixedly connected to its upper end surface. The connecting plate 5 drives the hanging block 6. The hanging block 6 drives the cutting tool 62. By moving the bottom plate 1 away from the side of the rotating motor 34, the distance between the two runners 36 can be controlled, and at the same time, the distance between the cutting tool 62 and the connecting plate 5 near the side of the rotating motor 34 can be controlled to cut product card strips with different length requirements. The synchronous control of the distance between the two runners 36 and the distance between the cutting tool 62 and the connecting plate 5 near the side of the rotating motor 34 realizes the purpose of being able to adapt to the cutting and sorting of product card strips with various different length requirements.

[0036] In order to avoid the skew of the cutting tool 62 during movement, a pair of symmetrically placed guiding rods 7 are fixedly connected to the connecting plate 5 near the side of the rotating motor 34. The end of the guiding rod 7 away from the rotating motor 34 sequentially passes through the hanging block 6 and the connecting plate 5 on the side away from the rotating motor 34. The hanging block 6 and the connecting plate 5 on the side away from the rotating motor 34 are both slidably connected to the guiding rod 7. By restricting the direction of movement of the hanging block 6 and the connecting plate 5 on the side away from the rotating motor 34 through the guiding rod 7, the skew of the connecting plate 5 on the side away from the rotating motor 34 during movement is avoided, and further the skew of the cutting tool 62 during movement is avoided.

[0037] In order to avoid the product card strip falling from the side of the cutting table 2 away from the alignment mechanism when cutting the product card strip, a strip-shaped plate 8 is fixedly connected to the side wall of the cutting table 2 away from the alignment structure. The height of the upper end of the strip-shaped plate 8 is higher than the height of the table surface of the cutting table 2 on the side away from the alignment mechanism. Through the blocking of the strip-shaped plate 8, when cutting the product card strip, the purpose of preventing the product card strip from falling from the side of the cutting table 2 away from the alignment mechanism is achieved.

[0038] In order to facilitate the movement of the mounting plate 31 on the side away from the rotating motor 34, the cutting table 2 is designed as a hollow shell. The two shell walls of the cutting table 2 perpendicular to the support plate 32 on the peripheral side are connected to the outside in a penetrating manner. One end of the cutting table 2 shell near the alignment mechanism is provided with a threaded rod 9. The threaded rod 9 and the rotating rod 35 are coaxially placed. Both ends of the threaded rod 9 are rotatably connected to the side wall of the cutting table 2 shell. A slider 91 is arranged inside the cutting table 2 shell. The upper end of the slider 91 is attached to the inner upper shell surface of the cutting table 2, and the lower end of the slider 91 is attached to the bottom plate 1. The threaded rod 9 passes through the slider 91 and is threadedly connected to the slider 91. The slider 91 can perform threaded engagement transmission along the threaded rod 9. The slider 91 is fixedly connected to the mounting plate 31 on the side away from the rotating motor 34. By rotating the threaded rod 9, due to the limitation of the bottom plate 1 and the cutting table 2 shell, the slider 91 cannot rotate with the threaded rod 9. The slider 91 performs threaded engagement transmission with the threaded rod 9, and the slider 91 moves along the threaded rod 9. The slider 91 drives the mounting plate 31 on the side away from the rotating motor 34 to move, achieving the purpose of facilitating the movement of the mounting plate 31 on the side away from the rotating motor 34.

[0039] In order to facilitate pushing the product card strips after cutting on the flat table surface of the cutting table 2 into the arc table surface of the cutting table 2, and then making the product card strips enter the swing mechanism, a pushing mechanism is provided at the end of the cutting table 2 shell away from the swing mechanism, and the pushing mechanism includes a second rotating shaft 101, and the second rotating shaft 101 is coaxially placed with the threaded rod 9, and both ends of the second rotating shaft 101 pass through the cutting table 2 shell and are rotatably connected to the cutting table 2 shell. A plurality of evenly distributed toggle components are fixedly connected to the second rotating shaft 101, and the toggle components include a sliding rod 102, and the sliding rod 102 is fixedly connected to the side wall of the second rotating shaft 101, and a sliding member 103 is sleeved on the sliding rod 102, and the sliding member 103 is slidably connected to the sliding rod 102, and the end of the sliding member 103 away from the second rotating shaft 101 is provided with a cone, and the sliding rod 102 is sleeved with a second spring 104, and one end of the second spring 104 is fixed to the side wall of the sliding rod 102, and the other end of the sliding rod 102 is fixed to the sliding rod 102. The second rotating shaft 101 is rotated, and the rotation of the second rotating shaft 101 drives each toggle component to rotate around the central axis of the second rotating shaft 101. When the toggle component rotates to pass through the strip groove 21, the second spring 104 pops out and pushes the sliding member 103 to slide along the sliding rod 102 away from the second rotating shaft 101, so that the upper end of the sliding member 103 can contact the product card strip on the flat table surface at the upper end of the cutting table 2, and the product card strip is pushed by the rotation of the toggle component, so as to achieve the purpose of pushing the product card strip after cutting from the flat table surface of the cutting table 2 into the circular table surface.

[0040] At the same time, the end of the sliding member 103 away from the second rotating shaft 101 is set to be conical, which facilitates the rotation of the toggle assembly in the cutting table 2 shell. When the toggle assembly rotates to be pressed and contacted with the cutting table 2 shell, the conical surface of the sliding member 103 away from the second rotating shaft 101 is pressed and contacted with the cutting table 2 shell, and the sliding member 103 and the cutting table 2 shell slide relative to each other along the conical surface on the sliding member 103, so that the sliding member 103 squeezes and compresses the second spring 104 to approach the central axis of the second rotating shaft 101, which facilitates the sliding member 103 to pass through the cutting table 2 shell when colliding and contacting with the cutting table 2 shell, thereby achieving the purpose of facilitating the rotation of the toggle assembly in the cutting table 2 shell.

[0041] In order to facilitate the control of the rotation of the threaded rod 9 and the second rotating shaft 101 and perform selective control on them, a first gear 11 placed coaxially is fixedly sleeved on the first rotating shaft 341. One end of the threaded rod 9 close to the rotating motor 34 is fixedly connected with a third rotating shaft 12. The third rotating shaft 12 and the threaded rod 9 are placed coaxially. A washer block 121 is fixedly sleeved on the third rotating shaft 12. A second gear 13 placed coaxially is fixedly sleeved on the third rotating shaft 12.

The third gear 14 is rotatably connected to the third rotating shaft 12. The third gear 14 is located at one end of the washer block 121 away from the cutting table 2. The diameters, module numbers, and tooth numbers of the third gear 14 and the second gear 13 are equal. An internally toothed sleeve 15 is sleeved on the washer block 121 in a sliding connection manner. The internally toothed sleeve 15 and the third rotating shaft 12 are placed coaxially. The inner side wall of the internally toothed sleeve 15 is provided with evenly distributed teeth. Both the second gear 13 and the third gear 14 can be engaged with the teeth on the inner tooth wall of the internally toothed sleeve 15. The distance between the second gear 13 and the third gear 14 is equal to the length of the internally toothed sleeve 15. An externally toothed sleeve 16 is sleeved on the internally toothed sleeve 15 coaxially. The outer side wall of the externally toothed sleeve 16 is in a gear ring shape. The externally toothed sleeve 16 is slidably connected to the internally toothed sleeve 15. The length of the externally toothed sleeve 16 is less than the length of the internally toothed sleeve 15. A plurality of evenly distributed second protrusions 151 are fixedly provided on the outer side wall of the internally toothed sleeve 15. A plurality of evenly distributed second clamping grooves 161 are formed on the inner side wall of the externally toothed sleeve 16. The second protrusions 151 and the second clamping grooves 161 correspond to each other one by one. The second protrusions 151 can slide relative to the second clamping grooves 161. A fourth gear 17 placed coaxially is fixedly sleeved on one end of the second rotating shaft 101 close to the rotating motor 34. The first gear 11 and the externally toothed sleeve 16 are engaged and connected through a first synchronous toothed belt 111. The end of the third gear 14 away from the washer block 121 and the fourth gear 17 are engaged and connected through a second synchronous toothed belt 141;

[0042] When it is necessary to rotate the threaded rod 9 to adjust the length of the cutting product strip, move the internally toothed sleeve 15 to make the internally toothed sleeve 15 approach the second gear 13, separate the internally toothed sleeve 15 from the third gear 14, and engage the internally toothed sleeve 15 with the second gear 13. At this time, turn on the rotating motor 34. The output end of the rotating motor 34 drives the first rotating shaft 341. The first rotating shaft 341 drives the first gear 11. The first gear 11 drives the first synchronous toothed belt 111. The first synchronous toothed belt 111 drives the externally toothed sleeve 16.
