Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic packaging bag production technology, specifically a positioning and labeling mechanism for a plastic packaging bag labeling machine. Background Technology
[0002] Plastic packaging bags are packaging bags made from plastic raw materials. They are very common in daily life because they are inexpensive and easy to produce. Most products use plastic packaging bags for packaging. When plastic bags are produced, some plastic bags will be labeled with information about the packaged product, such as barcodes and production dates. This requires labeling machines.
[0003] In labeling mechanisms for plastic bags, since the plastic strip is transported by a conveyor belt, the various rollers that transport the label carrier are all set horizontally. To prevent the label carrier from shifting to the left or right, a black plastic retaining ring is usually installed on some rollers. The plastic retaining ring is tightened by bolts to shrink and clamp the roller, thus blocking the side of the label carrier and preventing the label carrier from shifting.
[0004] However, each time the position of the black plastic retaining ring is adjusted, the bolts need to be loosened with an Allen wrench, and then the plastic retaining ring is adjusted and the bolts are tightened. The operation is quite cumbersome, and the large number of guide rollers results in a large number of retaining rings that need to be adjusted, which increases the complexity of the operation. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a positioning and labeling mechanism for a plastic packaging bag labeling machine to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning and labeling mechanism for a plastic packaging bag labeling machine, comprising a support plate and a roller body, wherein a stop block is connected to the top of the roller body, and a first anti-slip pad is connected to the bottom of the stop block, a stop strip is connected to one side of the stop block, and a second anti-slip pad is connected to the inner ring of the stop strip; a connecting piece is fixed to one side of the stop strip, and multiple slots are provided on the top of the connecting piece; a spring is connected inside the stop block, and a locking block is connected to the top of the spring.
[0007] By adopting the above technical solution, when the positions of the stop block and the stop strip need to be adjusted, the operator presses the locking block to displace it and compress the spring. Then, the operator bends the stop strip to increase its diameter, and the connecting piece is pulled out but not pulled out of the stop block, thus ending the contact between the stop block and the stop strip. Afterwards, the stop block and the stop strip can be moved to adjust their positions. The stop block is made of hard plastic and will not bend or deform, thus avoiding the phenomenon of the stop block and locking block becoming stuck and unable to move during operation. The stop strip is made of flexible plastic, which is easy to bend and deform, thus facilitating the adjustment of the position. The large diameter stop bar ends its contact with the roller body, and the small diameter stop bar contacts the roller body and bends the connecting piece. After adjustment, the worker holds the stop bar to reduce its bending diameter. At this time, the stop block and the stop bar contact the roller body, increasing friction to prevent displacement. The connecting piece moves down in the stop block and presses against the locking block. Then, the locking block is driven by a spring to move up into the locking groove for limiting, preventing the stop bar and the connecting piece from springing back. The setting of the first and second anti-slip pads increases the friction between the stop block and the stop bar, effectively preventing the stop block and the stop bar from being displaced by external forces such as vibration.
[0008] Furthermore, the top of the card block has a rounded corner in the middle, and a ramp is provided on the right side of the card block.
[0009] By adopting the above technical solution, the connecting piece is displaced and pressed down on the blocking block in the stop block, and then the blocking block is moved up into the slot by the spring for limiting.
[0010] Furthermore, the card block and the stop block are slidably connected, and the card block and the card slot are detachably connected.
[0011] By adopting the above technical solution, when it is necessary to adjust the position of the stop block and the stop bar, the worker presses the block to displace the block and compress the spring. Then the worker bends the stop bar to make the diameter of the stop bar larger, and the connecting piece is moved but not pulled out of the stop block.
[0012] Furthermore, both the stop block and the locking block are made of PA66 material, and both the stop strip and the connecting piece are made of TPEE material.
[0013] By adopting the above technical solution, the stop block is made of hard plastic, which will not bend or deform, thereby avoiding the phenomenon that the stop block and the clamp block bend or deform and become stuck and unable to move when the operator operates. The stop strip is made of flexible plastic, which is easy to bend and deform, thereby making it easier to increase the diameter of the stop strip to end the contact with the roller body, and to reduce the diameter of the stop strip to contact the roller body and bend the connecting piece.
[0014] Furthermore, both the first and second anti-slip mats are made of rubber material, and both the first and second anti-slip mats have anti-slip textures on their surfaces.
[0015] By adopting the above technical solution, the friction between the block and the strip is increased by setting the first and second anti-slip pads, which effectively prevents the block and the strip from shifting due to external forces such as vibration.
[0016] Furthermore, the outer surface of the support plate is respectively connected to a material roll, a roller body, a guide plate, a pressure plate, and a take-up roller, and a clamping rod passes through the outer surface of the take-up roller. A label carrier tape is connected between the material roll and the roller body, the guide plate, the pressure plate, and the take-up roller.
[0017] By adopting the above technical solution, during installation, the operator passes the label carrier through the gaps between multiple rollers and the gap between the guide plate and the pressure plate. Then, one end of the label carrier is placed into the groove at the bottom of the take-up roller, and finally, a clamping rod is inserted to limit the label carrier. The operator rotates the roll and the take-up roller to move the label carrier. The label on the label carrier is peeled off as it passes through the gap between the guide plate and the pressure plate, thus making contact between the label and the plastic packaging bag. The plastic packaging bag moves synchronously with the label carrier and the label, so that the entire label is peeled off from the label carrier and adheres to the top of the plastic packaging bag, thereby completing the labeling work. During this process, blocks and strips prevent the label carrier from shifting horizontally.
[0018] Furthermore, the top of the stop block is penetrated by a limiting plate, and the top two sides of the limiting plate are connected with second bolts. The limiting plate is detachably connected to the stop block by the second bolts.
[0019] By adopting the above technical solution, when the structure is damaged, the staff can first press the locking block and then open the stop bar. After that, the staff can remove the blocking block and the stop bar from the roller body and pull the connecting piece out of the blocking block. The staff can then remove the second bolt and the limiting plate in sequence to replace the locking block and the spring.
[0020] Furthermore, the spring is detachably connected to the stop.
[0021] By adopting the above technical solution, after the card block is removed from the stop block, the spring is exposed, and the staff can replace the spring at this time, which is convenient for maintenance.
[0022] Furthermore, the longitudinal section of the side of the card block is U-shaped, and the top of the card block abuts against the limiting plate. The outer surface and back of the card block are slidably connected to the limiting plate.
[0023] By adopting the above technical solution, the card block penetrates the limiting plate, making it easy for the staff to press the card block by hand to separate the card block from the card slot. At the same time, the step on the top of the card block abuts against the limiting plate to limit the highest position of the card block, preventing the phenomenon that the protrusion on the card block that matches the card slot will stick to the bottom of the limiting plate after the staff accidentally pulls out the connecting piece, thus preventing the connecting piece from being inserted.
[0024] Furthermore, a first bolt is inserted through both the lower surface of the outer surface of the block and one side of the outer surface of the strip, and the strip is detachably connected to the block via the first bolt.
[0025] By adopting the above technical solution, when the structure is damaged, the staff can first press the locking block and then open the stop bar. After that, the staff can remove the stop block and the stop bar from the roller body and pull the connecting piece out of the stop block. At this time, the staff can remove the first bolt to replace the stop block or the stop bar.
[0026] In summary, the present invention has the following main advantages:
[0027] 1. This utility model, through the arrangement of a stop block, a stop bar, a connecting piece, a slot, a locking block, and a spring, allows for convenient and quick operation when the positions of the stop block and the stop bar need to be adjusted. Pressing the locking block causes it to displace and compress the spring. Then, bending the stop bar increases its diameter, and the connecting piece is moved but not pulled out of the stop block, thus ending the contact between the stop block and the stop bar. After adjustment, the stop block and the stop bar can be moved to adjust their positions. After adjustment, pressing the stop bar reduces its bending diameter, increasing friction between the stop block and the stop bar and the roller body to prevent displacement. The connecting piece moves down in the stop block and presses against the locking block. Then, the spring drives the locking block to move upward into the slot for limiting, preventing the stop bar and the connecting piece from springing back. Compared to holding a wrench twice, inserting the wrench into the bolt and rotating it several times, operating the retaining ring, and removing the wrench, this method is convenient, quick, and tool-free.
[0028] 2. This utility model features a stop block and a stop bar. The stop block is made of hard plastic, which will not bend or deform, thus preventing the stop block and the locking block from bending and deforming and becoming stuck during operation. The stop bar is made of flexible plastic, which is easy to bend and deform, thus facilitating the increase of the stop bar diameter to end the contact with the roller body, as well as the decrease of the stop bar diameter to contact the roller body and bend the connecting piece; making operation convenient.
[0029] 3. By setting up the first and second anti-slip pads, this utility model increases the friction between the stop block and the stop strip, effectively preventing the stop block and the stop strip from shifting due to external forces such as vibration; thus increasing structural stability.

Detailed Implementation
[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0039] The embodiments of this utility model will be described below based on its overall structure.
[0040] Example 1:
[0041] A positioning and labeling mechanism for a plastic packaging bag labeling machine, such as 1- Figure 7As shown in the figure, the roller body includes a support plate 1 and a roller body 4. A stop block 9 and a locking block 13 are connected to the top of the roller body 4. Both the stop block 9 and the locking block 13 are made of PA66 material. A first anti-slip pad 15 is connected to the bottom of the stop block 9. A stop strip 10 is connected to one side of the stop block 9. The stop strip 10 and the connecting piece 11 are both made of TPEE material. A second anti-slip pad 16 is connected to the inner ring of the stop strip 10. Both the first anti-slip pad 15 and the second anti-slip pad 16 are made of rubber material, and both the first anti-slip pad 15 and the second anti-slip pad 16 have anti-slip textures on their surfaces. A connecting piece 11 is fixed to the side, and multiple slots 12 are opened on the top of the connecting piece 11. A spring 14 is connected inside the stop block 9, and a locking block 13 is connected to the top of the spring 14. The top of the locking block 13 has a rounded corner in the middle, and a ramp is provided on the right side of the locking block 13. The locking block 13 is slidably connected to the stop block 9, and the locking block 13 is detachably connected to the slots 12. When it is necessary to adjust the position of the stop block 9 and the stop bar 10, the operator presses the locking block 13 to displace the locking block 13 and compress the spring 14. Then, the operator bends the stop bar 10 to make the diameter of the stop bar 10 larger, and the connecting piece 11 is... The movement is initiated but not withdrawn from stop 9, thus ending the contact between stop 9 and stop bar 10. Afterwards, stop 9 and stop bar 10 can be moved to adjust their positions. Stop 9 is made of hard plastic and will not bend or deform, thus preventing the stop 9 and locking block 13 from bending and becoming stuck during operation. Stop bar 10, on the other hand, is made of flexible plastic, facilitating bending and deformation. This allows for increasing the diameter of stop bar 10 to end contact with roller 4, and decreasing the diameter of stop bar 10 to maintain contact with roller 4 and to bend connecting piece 11. After adjustment, the worker... The operator grips and presses the stop bar 10 to reduce its bending diameter. At this time, the stop block 9 and the stop bar 10 come into contact with the roller body 4, increasing the friction and preventing displacement. The connecting piece 11 moves down in the stop block 9 to press down the locking block 13. Then, the locking block 13 is driven upward by the spring 14 to enter the locking groove 12 for limiting, preventing the stop bar 10 and the connecting piece 11 from rebounding. The setting of the first anti-slip pad 15 and the second anti-slip pad 16 increases the friction between the stop block 9 and the stop bar 10, effectively preventing the stop block 9 and the stop bar 10 from being displaced by external forces such as vibration.
[0042] See Figure 1In the above embodiment, the outer surface of the support plate 1 is respectively connected to the material roll 2, roller 4, guide plate 5, pressure plate 6 and take-up roller 7. The outer surface of the take-up roller 7 is penetrated by a clamping rod 8. The material roll 2 is connected to the roller 4, guide plate 5, pressure plate 6 and take-up roller 7 by a label carrier 3. During installation, the operator passes the label carrier 3 through the gaps between the multiple rollers 4 and the gap between the guide plate 5 and the pressure plate 6. Then, one end of the label carrier 3 is placed into the bottom groove of the take-up roller 7. Finally, the clamping rod 8 is inserted to limit the label carrier 3. The operator rotates the material roll 2 and the take-up roller 7 to move the label carrier 3. The label on the label carrier 3 is peeled off when it passes through the gap between the guide plate 5 and the pressure plate 6, so that the label comes into contact with the plastic packaging bag. The plastic packaging bag moves synchronously with the label carrier 3 and the label, so that the entire label is peeled off from the label carrier 3 and adhered to the top of the plastic packaging bag, thereby completing the labeling work. During this process, the label carrier 3 is prevented from shifting horizontally by the stop block 9 and the stop strip 10.
[0043] Example 2:
[0044] Based on the above embodiment 1, in order to facilitate the replacement of the card block 13 and the spring 14, the following settings are now adopted.
[0045] See Figures 2-6 In the above embodiment, the top of the stop block 9 passes through the limit plate 18, and the top two sides of the limit plate 18 are connected with second bolts 19. The limit plate 18 is detachably connected to the stop block 9 through the second bolts 19, and the spring 14 is detachably connected to the stop block 9. When the structure is damaged, the worker can first press the locking block 13 and then open the stop bar 10. After that, the worker removes the stop block 9 and the stop bar 10 from the roller body 4 and pulls the connecting piece 11 out of the stop block 9. The worker then removes the second bolts 19 and the limit plate 18 in sequence, thereby replacing the locking block 13 and the spring 14. The longitudinal section of the side of the card block 13 is U-shaped, allowing the card block 13 to pass through the limiting plate 18, making it easy for the operator to press the card plate 13 by hand to separate the card plate 13 from the card slot 12. The top of the card block 13 abuts against the limiting plate 18, and the outer surface and back of the card block 13 are slidably connected to the limiting plate 18. The top of the card plate 13 abuts against the limiting plate 18 to limit the highest position of the card plate 13, preventing the phenomenon that the protrusion on the card block 13 that cooperates with the card slot 12 will stick to the bottom of the limiting plate 18 after the operator accidentally pulls out the connecting piece 11, thus preventing the connecting piece from being inserted.
[0046] Example 3:
[0047] Based on the above embodiment 1, in order to facilitate the replacement of the stop block 9, the stop bar 10 and the connecting piece 11, the following settings are now adopted.
[0048] See Figure 2 , Figure 3 and Figure 7In the above embodiment, a first bolt 17 is inserted through the lower outer surface of the stop block 9 and one side of the outer surface of the stop strip 10. The stop strip 10 is detachably connected to the stop block 9 through the first bolt 17. When the structure is damaged, the worker can first press the locking block 13 and then open the stop strip 10. After that, the worker can remove the stop block 9 and the stop strip 10 from the roller body 4 and pull the connecting piece 11 out of the stop block 9. At this time, the worker can remove the first bolt 17 to replace the stop block 9 or the stop strip 10.
[0049] The implementation principle of this utility model is as follows: First, the positioning and labeling mechanism is existing technology. This technical solution only uses a simple description of some of the structures, such as material roll 2, label carrier tape 3, roller, guide plate 5, pressure plate 6, winding roller 7, clamping rod 8, etc. The specific structure and working principle are public technologies, so this technical solution will not be described in detail.
[0050] During installation, the operator passes the label carrier 3 through the gaps between multiple rollers 4 and the gap between the guide plate 5 and the pressure plate 6. Then, one end of the label carrier 3 is placed into the groove at the bottom of the take-up roller 7. Finally, the clamping rod 8 is inserted to limit the label carrier 3. The operator rotates the material roll 2 and the take-up roller 7 to move the label carrier 3. The label on the label carrier 3 is peeled off as it passes through the gap between the guide plate 5 and the pressure plate 6, thus making contact between the label and the plastic packaging bag. The plastic packaging bag moves synchronously with the label carrier 3 and the label, so that the entire label is peeled off from the label carrier 3 and adheres to the top of the plastic packaging bag, thus completing the labeling work. During this process, the label carrier 3 is prevented from shifting horizontally by the stop block 9 and the stop strip 10.
[0051] When the positions of the stop block 9 and the stop bar 10 need to be adjusted, the operator presses the locking block 13 to displace the locking block 13 and compress the spring 14. Then, the operator bends the stop bar 10 to increase its diameter, and the connecting piece 11 is pulled and displaced but does not come out of the stop block 9, thus ending the contact between the stop block 9 and the stop bar 10. After that, the stop block 9 and the stop bar 10 can be moved to adjust their positions. The stop block 9 is made of hard plastic and will not bend or deform, thus avoiding the phenomenon that the stop block 9 and the locking block 13 bend and deform and become stuck and unable to move when the operator operates. The stop bar 10 is made of flexible plastic, which is easy to bend and deform, thus making it easier to increase the diameter of the stop bar 10 to end the contact with the roller body 4, and to reduce the diameter of the stop bar 10 to contact the roller body 4 and bend the connecting piece 11.
[0052] After adjustment, the operator presses down the stop bar 10 to reduce its bending diameter. At this time, the stop block 9 and the stop bar 10 contact the roller body 4 to increase friction and prevent displacement. The connecting piece 11 moves down in the stop block 9 to press down the locking block 13. Then, the locking block 13 is driven to move up into the locking groove 12 by the spring 14 to limit the movement and prevent the stop bar 10 and the connecting piece 11 from rebounding. The first anti-slip pad 15 and the second anti-slip pad 16 increase the friction between the stop block 9 and the stop bar 10, effectively preventing the stop block 9 and the stop bar 10 from being displaced by external forces such as vibration.
[0053] When the structure is damaged, the worker can first press the locking block 13 and then open the stop bar 10. After that, the worker can remove the stop block 9 and the stop bar 10 from the roller body 4 and pull out the connecting piece 11 from the stop block 9. At this time, the worker can remove the first bolt 17 to replace the stop block 9 or the stop bar 10; or the worker can remove the second bolt 19 and the limiting plate 18 in sequence to replace the locking block 13 and the spring 14. After the replacement is completed, the first bolt 17, the second bolt 19 and the limiting plate 18 can be reinstalled.
