Technical Field
[0001] This utility model belongs to the field of adhesive tape production technology, and in particular relates to a packaging device for adhesive tape production. Background Technology
[0002] Adhesive tape is a sticky strip material composed of a substrate and an adhesive. It connects two or more unconnected objects together by bonding. Adhesive tape can be classified into various types according to its function, such as high-temperature tape, double-sided tape, insulating tape, specialty tape, pressure-sensitive tape, and die-cut tape, to meet the needs of different industries. The adhesives for tape originally came from animals and plants. In the 19th century, rubber was the main component of adhesives, while in modern times, various polymers are widely used.
[0003] The existing authorized public account CN222452681U discloses a packaging device for tape production, comprising: a vertical plate, a clamping mechanism horizontally arranged on the right side of the vertical plate; the clamping mechanism includes a mounting plate horizontally arranged on the right side of the vertical plate, a sliding rod horizontally arranged on the inner side of the mounting plate, a sliding block slidably arranged on the surface of the sliding rod, and a tension spring sleeved on the surface of the sliding rod and to the left of the sliding block. This utility model provides a packaging device for tape production. By pulling the sliding frame to the right within the mounting plate, and then pulling the clamping plate upwards through the protrusion, the sliding frame is released, and the tension spring causes the sliding frame to move to the left. The clamping plate then clamps and limits the position of the tape. The operation is simple and convenient, making it very easy to clamp and fix the position of the tape without manual handling, thus effectively reducing the workload of workers and improving the packaging efficiency of the tape. However, the right end of the roll of the aforementioned packaging device for tape production lacks a limiting device, causing the tape to become unstable after being placed on the roll and resulting in displacement during packaging, making the packaging process difficult to operate. Furthermore, the film roll of this device is passively rotated by being pulled during packaging, which may cause the film to break and become damaged. Additionally, the blades of this device cannot maintain a fixed height during film cutting, causing inconvenience for operators who need to manually maintain the blade height at a relatively fixed position. Therefore, it is necessary to provide a packaging device for tape production that solves the above problems. Utility Model Content

The rotating block 4 and the rotating groove are set as a matching T-shaped structure, so that the rotating block 4 and the mounting box 2 form a rotating connection, thereby making the mounting base 3 and the mounting box 2 form a rotating connection. The diameter of the mounting base 3 is the same as part of the diameter of the rotating block 4. The diameter of the mounting base 3 is the same as the diameter of the opening on both sides of the inner side of the mounting box 2, so that the mounting base 3 plays a certain role in sealing the opening on both sides of the inner side of the mounting box 2.
[0030] Preferably, the mounting base 3 is configured with a notch structure, the inner width of the notch is the same as the diameter of the rotating shafts mounted on both sides of the film roll 5, the bottom of the inner side of the notch is configured with an arc-shaped structure adapted to the rotating shafts, the length of the rotating shafts at both ends of the film roll 5 is the same as the thickness of the mounting base 3, and the rotating shafts on both sides of the film roll 5 are fixedly mounted on the inner side of the notch of the mounting base 3 by fixing bolts, thereby fixing the film roll 5 between the two sets of mounting bases 3, so that the film roll 5 can rotate inside the mounting box 2;
[0031] Preferably, the connecting shaft 7 is installed in the through hole on the right side of the mounting box 2. The left end of the connecting shaft 7 is fixedly connected to the middle right side of the rightmost set of rotating blocks 4 in the two sets of rotating blocks 4. The right end of the connecting shaft 7 is flush with the right side of the mounting box 2 and fixedly connected to the middle left side of the first pulley 6, thereby connecting the first pulley 6 with the rotating block 4. The length of the mounting rod 8 is the same as the overall length of the mounting box 2. The right end of the mounting rod 8 passes through the through hole on the right side of the mounting box 2 and is flush with the right side of the mounting box 2. The right end of the mounting rod 8 is fixedly connected to the middle left side of the second pulley 9, thereby driving the mounting rod 8 to rotate through the second pulley 9.
[0032] Preferably, a circular through groove is provided on the left side of the mounting box 2, and the diameter of the limiting plate 11 is the same as that of the groove. The thickness of the three sets of fixing blocks 12 installed on the left side of the limiting plate 11 is less than the thickness of the limiting plate 11. The thickness of the limiting plate 11 is the same as the thickness of the left side of the mounting box 2. The fixing blocks 12 are fixedly installed in the fixing groove provided on the left side of the mounting box 2 by fixing bolts, thereby fixing the limiting plate 11 in the circular through groove. A through hole with the same diameter as the mounting rod 8 is provided in the middle of the limiting plate 11. The left end of the mounting rod 8 passes through the through hole and is flush with the left side of the limiting plate 11 and the mounting box 2. Two sets of arc-shaped through grooves are symmetrically provided on the limiting plate 11 so that the operator can move the limiting plate 11 by hand. Through the circular through groove on the left side of the mounting box 2, multiple tape rings that need to be packaged together can be placed on the mounting rod 8 through the circular through groove. After the number of tape rings placed on the mounting rod 8 reaches the standard, the limiting plate 11 is installed into the circular through groove, that is... The limiting plate 11 supports the left end of the mounting rod 8. Then, one end of the film roll 5 is manually wound to cover the outside of the multiple sets of tape rings on the mounting rod 8. Then, the second pulley 9 is rotated by the crank handle 13, causing the mounting rod 8 to rotate. The first pulley 6 rotates under the drive of the belt 10, which in turn drives the rotating block 4 to rotate. This drives the film roll 5 to rotate through the mounting seat 3, so that the mounting rod 8 and the film roll 5 rotate synchronously inside the mounting box 2. The two rotate in the same direction, so that the film on the film roll 5 can be wound at a uniform speed to cover the outside of the multiple sets of tape rings on the mounting rod 8. Then, the multiple sets of tape rings are packaged together by the film. The diameter of the first pulley 6 is larger than that of the second pulley 9, so that the rotation speed of the film roll 5 is less than that of the mounting rod 8, which meets the actual need that the diameter of the film roll 5 is larger than the diameter of the tape rings, and can ensure that the film on the film roll 5 is released at a uniform speed.
[0033] Preferably, the length of the guide plate 14 is the same as the inner length of the mounting box 2. The two ends of the guide plate 14 are fixedly connected to the top of the two inner ends of the mounting box 2, thereby fixing the guide plate 14 to the inner top of the mounting box 2. The top of the guide plate 14 is flush with the top of the mounting box 2. The guide plate 14 has three sets of through grooves with the same length. The diameter of the threaded tube 15 is the same as the inner width of the middle set of through grooves. The two ends of the through grooves are set as arc-shaped structures that are adapted to the threaded tube 15. The rotating ring 16 installed on the outer side of the threaded tube 15 is located in the middle of the outer side of the threaded tube 15. The inner diameter of the rotating ring 16 is the same as the outer diameter of the threaded tube 15. The rotating ring 16 is located in the grooves starting on both sides of the inner side of the middle through groove of the guide plate 14. The threaded tube 15 is installed into the middle through groove through the rotating ring 16. The threaded tube 15 can be rotated by the rotating wheel 18, so that the threaded tube 15 rotates in the middle through groove.
[0034] Preferably, the bottom of the threaded rod 17 is located at the bottom of the guide plate 14, and the bottom of the threaded rod 17 is fixedly connected to the top center of the cutting blade 19. The limiting rod 20 is located in two sets of through slots on both sides of the central through slot on the guide plate 14. The top of the limiting rod 20 is flush with the top of the threaded rod 17. By rotating the threaded tube 15, the threaded rod 17 can move along the threaded tube 15. Under the action of the two sets of limiting rods 20, the threaded rod 17 moves up and down but does not rotate, thereby driving the cutting blade 19 to move up and down at the bottom of the guide plate 14, thus adjusting the height of the cutting blade 19 inside the mounting box 2, so that the bottom cutting edge of the cutting blade 19 is aligned with the unfolded film on the film roll 5. When performing the tape ring packaging operation, the threaded tube 15 needs to be pushed to... With the threaded tube 15 positioned at the leftmost end of the guide plate 14, after the tape ring is packaged and the height of the cutting blade 19 is adjusted, the unfolded film can be precisely cut by moving the cutting blade 19 to the right along the through groove on the guide plate 14. Then, a small section of film is manually rolled onto the packaged tape ring, and the limiting plate 11 is removed. The packaged tape ring can then be removed from the mounting rod 8 through the left through groove of the mounting box 2. The next tape ring packaging operation can then be performed. Compared to manual film cutting, the cutting blade 19 of this device does not move vertically or wobble horizontally during film cutting, ensuring the stability of the cutting blade 19 and preventing film waste due to inaccurate manual cutting.
