Description

Technical Field

[0001] The present invention relates to the technical field of tag printing equipment, and specifically to a printing equipment for tags. Background Art

[0002] When clothing is sold to people, the clothing tag can inform people of some information about the clothing. It is one of the components of the clothing. The printing of tags is an essential link. Using printing equipment to print tags can efficiently and batch complete the tag printing work.

[0003] Existing tags can generally be divided into three categories, namely roll tags, additional sticker tags, and single tags. Among them, roll tags are relatively special. After the existing roll tags complete the printing operation, it is necessary to manually tear off the tags. Its structure is as Figure 11 shown. When working for a long time, the amount of manual labor required is also huge. Moreover, the serrated edge structure between the torn tags will also have a certain adverse impact on the beauty and use experience of the tags themselves. Therefore, in order to solve the above problems, we provide a printing equipment for tags. Summary of the Invention

[0004] The purpose of the present invention is to provide a printing equipment for tags in order to solve the problems that after the existing roll tags are printed, manual tag removal is required, the labor cost is high, and the serrated edge structure of the tags themselves will have an adverse impact on the beauty.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A printing equipment for tags, including a printing machine, several printing rollers rotatably installed inside the printing machine, and a conveyor belt horizontally installed below the inside of the printing machine, including:

[0006] A separation component horizontally arranged at the side end of the discharge port structure of the printing machine;

[0007] An edge grinding component horizontally arranged at the side end of the separation component;

[0008] The separation component includes a motor, a reciprocating thread groove, a sliding ring, a toothed ring, a first hollow rod, a second hollow rod, a large gear, a connecting rod, an upper clamping plate, and a lower clamping plate;

[0009] The motor is horizontally fixed to the outer side end of the printing press, and the output shaft of the motor horizontally penetrates into the interior of the printing press. The reciprocating thread groove is arranged on the outer side of the output shaft of the motor. The sliding ring is slidably sleeved on the outer side of the output shaft of the motor and is threadedly connected to the reciprocating thread groove. The toothed ring is rotatably sleeved on the outer side of the sliding ring. The first hollow rod is sleeved and fixed on the outer side of the output shaft of the motor. The second hollow rod is slidably sleeved inside the first hollow rod, and the side end of the second hollow rod is horizontally fixed to the toothed ring. The large gear is horizontally distributed at the side end of the output shaft of the motor, and the large gear is rotatably connected to the inner wall of the printing press. The upper clamping plate and the lower clamping plate are symmetrically distributed in the vertical direction and are slidably distributed at the upper and lower ends of the discharge port structure of the printing press. The upper clamping plate is connected to the side end of the large gear through the connecting rod. The two ends of the connecting rod are respectively rotatably connected to the upper clamping plate and the large gear, and the connecting rod is eccentrically connected to the large gear.

[0010] By providing a large gear driven by a motor, the connecting rod is driven by the large gear to perform eccentric rotation. The eccentrically rotating connecting rod pushes the upper clamping plate to move horizontally. While the upper clamping plate moves horizontally, it will continuously approach the lower clamping plate until the upper clamping plate and the lower clamping plate are in contact, squeezing the tag located between the two. And as the upper clamping plate continues to move, the clamped tag is torn off. In this way, reciprocatingly, the separation of the tags is completed, saving labor costs while improving the function of the equipment.

[0011] As a further scheme of the present invention: The edge grinding assembly includes a small gear, a connecting block, a grinding roller and a crawler belt;

[0012] The small gear is horizontally distributed at the side end of the large gear. The connecting block is horizontally fixed to the side end of the small gear. The side end of the connecting block is rotatably connected to the inner wall of the printing press. The grinding roller is rotatably installed inside the printing press. The grinding roller is horizontally distributed at the side end of the conveyor belt, and the outer periphery of the side end of the grinding roller and the connecting block are both sleeved inside a crawler belt.

[0013] By providing a toothed ring structure sleeved on the output shaft of the motor, as the toothed ring continuously translates until it meshes with the small gear, the small gear is caused to rotate. Thus, the grinding roller is driven to rotate synchronously through the crawler belt. The rotating grinding roller will grind the side end of the torn tag to smooth the serrated edge of the tag side end, thereby improving the aesthetics of the tag. At the same time, the practicality of the equipment is increased.

[0014] As a further scheme of the present invention: A rotating disk is horizontally fixed to the side end of the motor, and a pressure roller is eccentrically installed at the side end of the rotating disk.

[0015] By providing a rotating disk that rotates synchronously with the motor, the rotating disk drives the pressure roller to rotate. When the two clamping plates pull the tag, the pressure roller just squeezes above another tag, thus cooperating with the clamping plates to better pull the tag and making the separation device work more perfectly.

[0016] As a further solution of the present invention: Two springs are horizontally fixed to the side end of the lower clamping plate, and the other sides of the two springs are horizontally fixed to the inner wall of the printing machine.

[0017] By providing springs to exert a force on the lower clamping plate, when the lower clamping plate moves horizontally, it will first squeeze the springs, and when the connecting rod drives the upper clamping plate to move back to its original position, the lower clamping plate that has lost the restraining force will, under the drive of the extended springs, move back to its original position, thus ensuring the perfection of the equipment operation.

[0018] As a further solution of the present invention: An arc-shaped plate is horizontally fixed inside the printing machine, and the arc-shaped plate is horizontally distributed between the grinding roller and the conveyor belt.

[0019] By providing an arc-shaped plate to guide the transportation of the tag, the tag transported forward from the conveyor belt will reach above the grinding roller along the upper surface of the arc-shaped plate and pass above the grinding roller, thus ensuring that the tag can effectively contact the grinding roller and enabling the grinding roller to function after working, making the equipment more perfect.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] By providing a large gear driven by a motor, the large gear drives the connecting rod to rotate eccentrically. The eccentrically rotating connecting rod pushes the upper clamping plate to move horizontally. While the upper clamping plate moves horizontally, it will continuously approach the lower clamping plate until the upper clamping plate fits with the lower clamping plate, squeezing and pulling the tag located between them to tear off the clamped tag. By repeating this process, the separation of the tag is completed, saving labor costs while improving the function of the equipment. And as the toothed ring continuously translates until it meshes with the small gear, causing the small gear to rotate, and then driving the grinding roller to rotate synchronously through the crawler. The rotating grinding roller will polish the side end of the torn tag to make the serrated edge of the tag side end smooth, thus improving the aesthetics of the tag and increasing the practicality of the equipment. The rotating disk that rotates synchronously with the motor drives the pressure roller to rotate. When the two clamping plates pull the tag, the pressure roller just squeezes above another tag, thus cooperating with the clamping plates to better pull the tag and making the separation device work more perfectly.

The following describes the embodiments according to the overall structure of the present invention.

[0036] Refer to Figures 1 to 10, in an embodiment of the present invention, a printing device for a hanging tag includes a printing press 1, a plurality of printing rollers 2 rotatably installed inside the printing press 1, and a conveyor belt 3 horizontally installed below the inside of the printing press 1, including: a separating component 4 horizontally arranged at the side end of the discharge port structure of the printing press 1; a grinding edge component 5 horizontally arranged at the side end of the separating component 4; the separating component 4 includes a motor 401, a reciprocating thread groove 402, a sliding ring 403, a toothed ring 404, a first hollow rod 405, a second hollow rod 406, a large gear 407, a connecting rod 408, an upper clamping plate 409, and a lower clamping plate 410; the motor 401 is horizontally fixed to the outer side end of the printing press 1, and the output shaft of the motor 401 horizontally penetrates into the inside of the printing press 1. The reciprocating thread groove 402 is arranged on the outer side of the output shaft of the motor 401. The sliding ring 403 is slidably sleeved on the outer side of the output shaft of the motor 401 and is threadedly connected to the reciprocating thread groove 402. The toothed ring 404 is rotatably sleeved on the outer side of the sliding ring 403. The first hollow rod 405 is sleeved and fixed on the outer side of the output shaft of the motor 401. The second hollow rod 406 is slidably sleeved inside the first hollow rod 405, and the side end of the second hollow rod 406 is horizontally fixed to the toothed ring 404. The large gear 407 is horizontally distributed at the side end of the output shaft of the motor 401, and the large gear 407 is rotatably connected to the inner wall of the printing press 1. The upper clamping plate 409 and the lower clamping plate 410 are symmetrically distributed in the vertical direction and are slidably distributed at the upper and lower ends of the discharge port structure of the printing press 1. The side end of the upper clamping plate 409 is connected to the side end of the large gear 407 through the connecting rod 408. The two ends of the connecting rod 408 are respectively rotatably connected to the upper clamping plate 409 and the large gear 407, and the connecting rod 408 is eccentrically connected to the large gear 407. A sliding block 12 is horizontally arranged at the side end of the upper clamping plate 409, and the upper clamping plate 409 slides above the discharge port structure of the printing press 1 through the sliding block 12.

[0037] Among them, Figure 11 is a schematic structural diagram of a roll-type hanging tag in the prior art.

[0038] In this embodiment: The user places the end of the tag roll to be printed above the conveyor belt 3 from the feeding port of the printing machine 1, and starts the entire device at the same time. At this time, the conveyor belt 3 starts to rotate, transporting the tags into the interior of the printing machine 1. Meanwhile, several printing rollers 2 inside the printing machine 1 start to rotate and come into contact with the upper surface of the tags. While rotating, the dye is printed onto the tags. When the printed tags reach the discharge port of the printing machine 1 and are above the lower clamping plate 410, the entire device is stopped immediately, and then the motor 401 is started. The motor 401 rotates, driving the sliding ring 403 to move horizontally along the reciprocating thread groove 402. While the sliding ring 403 moves, it drives the toothed ring 404 to move synchronously. The toothed ring 404 drives the second hollow rod 406 to extend outward from the inside of the first hollow rod 405. At the same time, the first hollow rod 405 fixedly connected to the output shaft of the motor 401 will drive the toothed ring 404 to rotate through the second hollow rod 406, causing the toothed ring 404 to rotate while moving horizontally. The rotating toothed ring 404 will engage with the large gear 407 and, by rotating synchronously with the large gear 407, pull the eccentric connecting rod 408. While the connecting rod 408 rotates, it will continuously push and pull the upper clamping plate 409 to move. The moving upper clamping plate 409 continuously approaches the lower clamping plate 410 until the two fit together. The upper clamping plate 409 continues to move, pushing the lower clamping plate 410 to move horizontally and pulling the tags, thereby tearing off the tags located between the two layers. This process is repeated to complete the separation action between the tags.

[0039] In the above embodiment, it should be supplemented that the motor 401 is reduced in speed through a planetary speed reducer to ensure that the overall operation is at a low speed and facilitate the smooth engagement between the toothed ring 404 and the large gear 407.

[0040] In the above solution, considering that after the tags are torn apart, the serrated edges between the tags will affect the overall aesthetics of the tags. Therefore, it is necessary to add a edge grinding component 5 to polish the sides of the tags to ensure the quality of the finished tags. The specific operation is as follows.

[0041] Refer to Figures 2 to 5 、 Figure 7 、 Figure 10 The edge grinding component 5 includes a small gear 501, a connecting block 502, a grinding roller 503, and a crawler 504;

[0042] The small gear 501 is horizontally distributed at the side end of the large gear 407. The connecting block 502 is horizontally fixed to the side end of the small gear 501. The side end of the connecting block 502 is rotatably connected to the inner wall of the printing machine 1. The grinding roller 503 is rotatably installed inside the printing machine 1. The grinding roller 503 is horizontally distributed at the side end of the conveyor belt 3, and both the side end of the grinding roller 503 and the periphery of the connecting block 502 are sleeved inside a crawler 504.

[0043] In this embodiment: after the two tags are torn apart, the sides of the two tags are just located on both sides of the grinding roller 503. As the toothed ring 404 continues to translate, the toothed ring 404 will first lose the meshing state with the large gear 407 and then mesh with the small gear 501, driving the small gear 501 to rotate. The small gear 501 then drives the grinding roller 503 to rotate synchronously through the track 504. The rotating grinding roller 503 will polish the serrated edges of the tags located on both sides of it, thereby improving the aesthetics of the tags.

[0044] In the first embodiment, considering that if only the upper clamping plate 409 and the lower clamping plate 410 are used to pull the tags, when the tags are torn apart, the tags located at the rear will also be affected by the force and shift, thus affecting the impact of the printing roller 2 on the tags. Therefore, an additional restraining force is required to restrain the tags at the rear to ensure the quality of tag printing. The specific operation is as follows.

[0045] Refer to Figure 2 、 Figures 4 to 6 A rotating disk 6 is horizontally fixed to the side end of the motor 401, and a pressing roller 7 is eccentrically installed at the side end of the rotating disk 6.

[0046] In this embodiment: when the large gear 407 pulls the eccentric connecting rod 408 to drive the upper clamping plate 409 to move and clamp the tag, the motor 401 drives the rotating disk 6 to rotate, and the pressing roller 7 located at the side end of the rotating disk 6 also squeezes the tags at the rear synchronously. As the upper clamping plate 409 continues to pull, combined with the squeezing of the pressing roller 7 on the tags at the rear, the two tags are better torn apart;

[0047] It should be added that: the equipment uses a quick-drying coating. Therefore, the pressing roller 7 pressing down will not affect the printed tag products.

[0048] In the first embodiment, considering that the tags torn off by the upper clamping plate 409 and the lower clamping plate 410 will accumulate at the discharge port structure of the printing machine 1, thus blocking the discharge port of the printing machine 1. Therefore, an additional conveying source is required to convey the torn-off tags to ensure the normal operation of the equipment. The specific operation is as follows.

[0049] Refer to Figures 2 to 4 A conveying roller 8 is rotatably installed above the inside of the discharge port structure of the printing machine 1, and the conveying roller 8 is horizontally distributed at the side end of the upper clamping plate 409.

[0050] In this embodiment: the tags torn off by the upper clamping plate 409 and the lower clamping plate 410 will accumulate at the discharge port structure of the printing machine 1. After completing one cycle of separation and edge grinding work, the user then starts the entire equipment. At this time, the conveying roller 8 starts to rotate, thereby conveying the tags accumulated in the discharge port of the printing machine 1 out.

[0051] It should be noted that: The printing machine 1 is internally provided with a power mechanism for driving the synchronous rotation of the conveyor belt 3, the printing roller 2, and the conveying roller 8.

[0052] In the first embodiment, considering that after the upper clamping plate 409 moves in a reset manner, the lower clamping plate 410 will still pause at the current position, thus losing its clamping function. Therefore, an additional power source needs to be set for the squeezed and moved lower clamping plate 410 to drive the lower clamping plate 410 to move in a reset manner, so as to ensure the normal operation of the equipment. The specific operation is as follows.

[0053] Refer to Figures 2 to 4 , two springs 9 are horizontally fixed to the side end of the lower clamping plate 410, and the other sides of the two springs 9 are horizontally fixed to the inner wall of the printing machine 1.

[0054] In this embodiment: As the motor 401 rotates, after driving the connecting rod 408 to rotate for a half cycle, the continuous movement of the connecting rod 408 will pull the upper clamping plate 409 to move in a reverse reset manner. At this time, the two springs 9 that lose the influence of the limiting force start to stretch, and the stretched springs 9 will horizontally push the lower clamping plate 410, so that the lower clamping plate 410 moves in a reset manner, so that in the next cycle, it can continue to cooperate with the upper clamping plate 409 to perform a pulling action on the tag.

[0055] In the first embodiment, considering that when the motor 401 rotates, the single sliding ring 403 will be driven by the reciprocating thread groove 402 to rotate synchronously and lose the ability to move horizontally. Therefore, the sliding ring 403 needs to have an additional structure to support its reciprocating horizontal movement. The specific operation is as follows.

[0056] Refer to Figure 6 , Figure 8 , an L-shaped rod 10 is vertically fixed inside the printing machine 1, and the side end of the L-shaped rod 10 horizontally penetrates through the sliding ring 403.

[0057] In this embodiment: When the motor 401 rotates, the reciprocating thread groove 402 on the output shaft of the motor 401 will be driven by the motor 401 to rotate synchronously. The rotating reciprocating thread groove 402 will drive the sliding ring 403 to rotate synchronously, and the rotating sliding ring 403 will be restricted by the extrusion of the L-shaped rod 10, so it cannot rotate and can only move horizontally along the shape of the reciprocating thread groove 402, thereby driving the gear ring 404 sleeved on its outer side to move horizontally.

[0058] In the first embodiment, considering that when the first hollow rod 405 rotates, the second hollow rod 406 without structural constraints cannot rotate synchronously with it, which will cause the toothed ring 404 to lose its function as it cannot rotate synchronously with the motor 401. Therefore, to ensure the normal operation of the equipment, the specific operation is as follows.

[0059] Referring to Figures 4 to 6 、 Figures 8 to 9 , a sliding groove 11 is formed on the outer wall of the second hollow rod 406, and the protruding structure inside the first hollow rod 405 is slidably engaged inside the sliding groove 11.

[0060] In this embodiment: when the first hollow rod 405 rotates synchronously with the rotation of the motor 401, affected by the engaging structure of the protruding structure on the inner wall of the first hollow rod 405 and the sliding groove 11, the second hollow rod 406 will rotate synchronously with the first hollow rod 405. While the second hollow rod 406 rotates, it will drive the toothed ring 404 to rotate synchronously. And as the sliding ring 403 extends outwards, the toothed ring 404 and the second hollow rod 406 will extend synchronously, and the protruding structure located on the inner wall of the first hollow rod 405 will slide synchronously inside the sliding groove 11, thus ensuring the normal operation of the equipment.

[0061] In the first embodiment, considering that there is a height difference between the frosted roller 503 and the conveyor belt 3, it will cause the printed tags to not be edge-milled by the frosted roller 503, and at the same time, they cannot be smoothly sent out from the discharge port of the printing machine 1 and will accumulate inside the printing machine 1, thus having an adverse effect on the operation of the equipment. Therefore, a guiding structure is needed to guide the conveyance of the tags, and the specific operation is as follows.

[0062] Referring to Figure 2 、 Figure 4 、 Figure 7 , an arc-shaped plate 505 is horizontally fixed inside the printing machine 1, and the arc-shaped plate 505 is horizontally distributed between the frosted roller 503 and the conveyor belt 3.

[0063] In this embodiment: when the entire equipment starts to operate, the conveyor belt 3 rotates, thereby conveying the tags located above it to the side. As the tags are continuously conveyed, the tags will come into contact with the arc-shaped plate 505 and adhere to the upper surface of the arc-shaped plate 505. The tags will slide along the upper surface of the arc-shaped plate 505 until they slide over the top of the frosted roller 503 and finally slide out from the discharge port of the printing machine 1.

[0064] In the first embodiment, considering that the toothed ring 404 moves horizontally while rotating itself, in order to enable the rotating toothed ring 404 to engage with the large gear 407 and the small gear 501, the large gear 407 and the small gear 501 themselves need to have certain structural features for the toothed ring 404 to make flexible contact and engage with the two. The specific operation is as follows.

[0065] Referring to Figure 2 , Figures 4 to 7 , Figure 10 , the sides of the large gear 407 and the small gear 501 are both plane structures that slope inward.

[0066] In this embodiment, when the motor 401 rotates to drive the sliding ring 403 to move horizontally along the reciprocating thread groove 402 and push the toothed ring 404 to move horizontally, the toothed ring 404 rotates while moving horizontally. The rotating toothed ring 404 will come into contact with the sides of the large gear 407 and the small gear 501 in turn, and the inclined plane structures at the side ends of the large gear 407 and the small gear 501 will reduce the collision resistance received by the toothed ring 404, so that the toothed ring 404 can mesh with the large gear 407 and the small gear 501 more gently.

[0067] It should be added that: the motor 401 rotates slowly. An additional planetary reducer can be installed at the side end of the motor 401 to control the rotation speed of the motor 401, so that the meshing of the toothed ring 404 with the large gear 407 and the small gear 501 is more gentle. And the diameter of the small gear 501 is small. By changing the diameter ratio of the meshing gears, the purpose of slow rotation of the motor 401 and accelerated rotation of the grinding roller 503 is achieved.

[0068] Working principle: The user places the end of the tag roll to be printed above the conveyor belt 3 from the feeding port of the printing machine 1, and starts the entire device at the same time. At this time, the conveyor belt 3 starts to rotate, conveying the tags into the interior of the printing machine 1. Meanwhile, a number of printing rollers 2 inside the printing machine 1 start to rotate and come into contact with the upper surface of the tags. While rotating, the dye is printed onto the tags. When the printed tags reach the discharging port of the printing machine 1 and are above the lower clamping plate 410, the user first stops the entire device, and then starts the motor 401. The motor 401 rotates, driving the sliding ring 403 to move horizontally along the reciprocating thread groove 402. While the sliding ring 403 moves, it drives the toothed ring 404 to move synchronously. The toothed ring 404 drives the second hollow rod 406 to extend outward from the interior of the first hollow rod 405. At the same time, the first hollow rod 405 fixedly connected to the output shaft of the motor 401 will drive the toothed ring 404 to rotate through the second hollow rod 406, resulting in the toothed ring 404 moving horizontally and rotating simultaneously. The rotating toothed ring 404 meshes with the large gear 407 and, by rotating synchronously with the large gear 407, pulls the eccentric connecting rod 408. While the connecting rod 408 rotates, it continuously pushes and pulls the upper clamping plate 409 to move. The moving upper clamping plate 409 continuously approaches the lower clamping plate 410 until the two are in contact. The upper clamping plate 409 continues to move, pushing the lower clamping plate 410 to move horizontally and pulling the tags, thereby tearing off the tags located between the two layers. This process is repeated to complete the separation action between the tags; after the two tags are torn apart, the sides of the two tags are just located on both sides of the grinding roller 503. And as the toothed ring 404 continues to translate, the toothed ring 404 will first lose the meshing state with the large gear 407 and then mesh with the small gear 501, driving the small gear 501 to rotate. The small gear 501 then drives the grinding roller 503 to rotate synchronously through the track 504. The rotating grinding roller 503 will smooth the serrated edges of the tags located on both sides of it, thereby improving the aesthetics and touch feeling of the tags.

[0069] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
