Description

Technical Field

[0001] This utility model relates to the field of packaging technology for injection vials, and in particular to a roll-up structure for packaging tape for injection vials. Background Technology

[0002] The unwinding structure of the packing tape for injection vials typically consists of an unwinding roller and a tension control device. The unwinding roller is used to mount the tape roll and enable it to rotate and unwind. The tension control device adjusts the tension of the tape during the unwinding process to ensure that the tape is released smoothly and evenly, avoiding situations such as slack or excessive tightness. This meets the stable supply requirements of tape during the packing process. Furthermore, the structural design takes into account the ease of installation and replacement of the tape roll, improving the efficiency and stability of the packing work.

[0003] A search revealed Chinese Patent Publication No. CN203473605U, which discloses a tape roll storage support plate structure. This structure includes at least one support plate with multiple flaps and corresponding insertion holes around its perimeter, forming an accommodating space between the flaps and holes. In use, the tape roll can be horizontally placed against the accommodating space of one support plate, and then the corresponding support plate can be placed against the other side of the tape roll. The flaps of the corresponding support plate are then folded towards the tape roll, and the corresponding support plate is simultaneously placed against the tape roll. The flaps of the plate are inserted into the insertion holes of the carrying plate on the other side of the tape roll. By restricting the movement space of the tape roll, the flaps prevent multiple stacked tape rolls from slipping or tipping over due to shaking or collision during transportation. The tape roll can be stably fixed in its original position. In actual operation, it was found that when the binding structure was used to bind the packaging box, although the tape wrapped around the packaging box was guided by the guide wheels, it was still a bit loose after binding, and the packaging box could easily fall off. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tape unwinding structure for packaging boxes of injection vials, which aims to improve the problem in the prior art that although the tape wrapped around the packaging box is guided by guide wheels, it is still somewhat loose after binding, and the packaging box is easy to fall off.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a packaging tape unwinding structure for injection vials, comprising a machine body 1, a connecting rod 12 mounted on the middle of the front side of the machine body 1, multiple guide rollers 9 rotatably connected at equal intervals on the front side of the machine body 1, a tension roller 10 rotatably connected to the middle of the front side of the connecting rod 12, a fixed base 13 fixedly connected to the bottom of the front side of the machine body 1, an elastic element 11 fixedly connected to the top of the fixed base 13, the top of the elastic element 11 being fixedly connected to the bottom of the tension roller 10, and a... The unwinding roller 5 has a tape 6 installed on its outer side. The tape 6 can be stably output through the installation of the tensioning roller 10. A cutting mechanism 2 is installed on the front right end of the machine body 1. The cutting mechanism 2 is used to cut the tape 6. A screw 7 is threadedly connected to the top of the front right end of the machine body 1. A slot plate 8 is installed on the outer side of the screw 7. The installation of the slot plate 8 facilitates the replacement of the label plate 19. The label plate 19 is set in the middle of the slot plate 8. The installation of the label plate 19 facilitates the reminder to the staff.

[0040] Specifically, the tape roll is placed on the unwinding roller 5, and then the tape 6 is drawn out from the roll. The tape 6 is guided through the first guide roller 9, and then continues to the tension roller 10. After passing through another guide roller 9, the tape 6 is finally guided into the packaging and binding mechanism. The tension roller 10 is mounted on a connecting rod 12, which is hinged to the machine body 1 to ensure its stability. One end of the tension roller 10 is connected to an elastic element 11, and the other end of the elastic element 11 is connected to a fixed seat 13. The elastic element 11 provides a continuous pulling force on the connecting rod 12, so that the tape can always be kept in a taut state, thereby ensuring the continuity and stability of the packaging process. Through the above process, the working efficiency of this device is improved, and the consistency and reliability of the packaging quality are also ensured.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The cutting mechanism 2 includes a second blade 203, which is fixedly connected to the right end of the front middle of the machine body 1. The top of the second blade 203 is rotatably connected to a first blade 202. A rotating cylinder 207 is rotatably connected to the middle of the right side of the front end of the machine body 1. A turntable 201 is fixedly connected to the outside of the rotating cylinder 207. A connecting short column 206 is fixedly connected to the left end of the front side of the turntable 201. A connecting rod 204 is fixedly connected to the left end of the connecting short column 206. The left end of the connecting rod 204 is fixedly connected to the right end of the first blade 202. A spring 205 is fixedly connected to the rear right side of the first blade 202. A fixing cylinder 3 is fixedly connected to the right end of the turntable 201. A protective sleeve 4 is installed on the outside of the fixing cylinder 3. The installation of the fixing cylinder 3 facilitates the rotation of the turntable 201.

[0042] Specifically, when it is necessary to cut the tape 6, first rotate the rotating cylinder 207. Since the outer side of the rotating cylinder 207 is fixedly connected to the turntable 201, the turntable 201 rotates accordingly. The connecting short column 206 on the left side of the front end of the turntable 201 moves accordingly, thereby driving the connecting rod 204 to move. The left end of the connecting rod 204 is fixedly connected to the right end of the first blade 202. Therefore, the movement of the connecting rod 204 will cause the first blade 202 to rotate around its connection point with the second blade 203. During the movement of the first blade 202, the spring 205 at its right rear end will be compressed. When the first blade 202 rotates to the appropriate position, the tape 6 is cut. After the cutting is completed, the rotating cylinder 207 rotates in the opposite direction. The elastic force of the spring 205 will cause the first blade 202 to return to the initial position, preparing for the next cutting. The second blade 203 is fixed at the right end of the middle of the front side of the machine body 1. It plays the role of supporting and cooperating with the first blade 202 to cut the tape 6.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A storage box 14 is fixedly connected to the bottom right side of the front of the body 1. A rotating short column 15 is rotatably connected to the top right side of the storage box 14. A cover plate 16 is fixedly connected to the left end of the rotating short column 15. A handle 17 is fixedly connected to the top of the cover plate 16. An anti-slip sleeve 18 is installed on the outside of the handle 17.

[0044] Specifically, the installation of the storage box 14 facilitates the storage and use of parts; the installation of the cover plate 16 prevents dirt from falling into the storage box 14; the installation of the handle 17 facilitates the opening and closing of the cover plate 16; and the installation of the anti-slip sleeve 18 prevents the hand from slipping when opening and closing the cover plate 16.

[0045] Working principle: The tape roll is placed on the unwinding roller 5. After the tape 6 is drawn out, it passes through the first guide roller 9 to the tension roller 10 and then to another guide roller 9, and finally enters the packaging and bundling mechanism to package the local packaging box. The tension roller 10 is mounted on a connecting rod 12, which is hinged to the machine body 1. One end of the tension roller 10 is connected to the elastic element 11, and the other end of the elastic element 11 is connected to the fixed seat 13. The elastic element 11 has a pulling force on the connecting rod 12. The elastic element 11 can keep the tape in a taut state, thereby improving the working efficiency of this device.

[0046] When it is necessary to cut the tape 6, the rotating cylinder 207 begins to rotate. Since the outer side of the rotating cylinder 207 is fixedly connected to the turntable 201, the turntable 201 will rotate together with the rotating cylinder 207. The connecting short column 206 fixedly connected to the front left end of the turntable 201 will move with the rotation of the turntable 201. The connecting rod 204 fixedly connected to the left end of the connecting short column 206 will also move accordingly. Since the left end of the connecting rod 204 is fixedly connected to the right end of the first blade 202, the connecting rod 204 will drive the first blade 202 to rotate around it and the second blade 203. The connection point rotates, at which time the first blade 202 rotates around the center. During the movement of the first blade 202, the spring 205 fixedly connected to its right rear end will be compressed. When the first blade 202 rotates to a certain extent, it can cut the tape 6. After the cutting is completed, the rotating cylinder 207 rotates in the opposite direction. Under the elastic force of the spring 205, the first blade 202 will return to the initial position to prepare for the next cutting operation. The second blade 203 is fixedly connected to the right end of the front middle of the machine body 1, which plays the role of supporting and cooperating with the first blade 202 to cut the tape 6.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
