Description

Technical Field

[0001] This application relates to the field of self-adhesive technology, specifically to a roller for roll self-adhesive labels. Background Technology

[0002] Self-adhesive labels, also known as pressure-sensitive labels, are composite materials made of paper, film, or special materials as the face stock, coated with adhesive on the back, and with silicone-coated release paper as the backing paper. Currently, roll-type self-adhesive labels are produced in a continuous long strip structure, which needs to be wound onto the roll to form a roll structure during packaging and transportation.

[0003] An existing patent (publication number: CN209009866U) discloses a roller for roll-type self-adhesive labels. The roller body has a first receiving groove and a second receiving groove at both ends. A first connecting mechanism is disposed in the first receiving groove, and a second connecting mechanism is disposed in the second receiving groove. A first driving mechanism is disposed in the first receiving groove, and a second driving mechanism is disposed in the second receiving groove. The first driving mechanism can drive the first connecting mechanism to be inserted into or pushed out of the first receiving groove, and the second driving mechanism can drive the second connecting mechanism to be inserted into or pushed out of the second receiving groove. This utility model has the advantages of simple structure and improved space utilization.

[0004] The groove on the first connector and the protrusion on the second connector of the aforementioned cylindrical shaft make it easier to connect the various rolls of self-adhesive labels by means of the groove and the protrusion. Furthermore, the number of grooves and protrusions is matched. Preferably, this utility model has several grooves and protrusions, which makes the connection structure between the first connector and the second connector more stable. However, in actual use, since the protrusion needs to be inserted into the interior of the groove, and the protrusion is rectangular, precise alignment is often required during insertion, which affects loading efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a roller for roll-type self-adhesive labels, which has advantages such as easy docking and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a roller shaft for roll adhesive tape, comprising a cylinder body and a male ring and a female ring that are slidably inserted at both ends of the cylinder body, a cross is fixedly connected to the middle of the inner wall of the cylinder body, a bidirectional threaded rod is rotatably connected to the center of the cross, the bidirectional threaded rod is on the same axis as the cylinder body, and a driving plate is fixedly connected to the ends of the male ring and the female ring that are close to each other, and the two driving plates are respectively threaded to both ends of the bidirectional threaded rod;

[0007] The male ring is fixedly connected to a set of circumferentially arranged inserts at the end away from the cylinder, each of the inserts being trapezoidal. The outer surface of the female ring at the end away from the cylinder is provided with a set of circumferentially arranged trapezoidal grooves.

[0008] The above solution, through the design of trapezoidal inserts and trapezoidal grooves, greatly simplifies the connection process between the male and female rings. The trapezoidal structure not only provides convenient guidance, allowing the inserts to easily slide into the trapezoidal grooves, but also ensures the stability of the connection. This design effectively avoids the precision required for the docking of traditional rectangular protrusions and grooves, thus significantly improving the efficiency of loading and unloading. The threaded connection between the bidirectional threaded rod and the drive plate, combined with the sliding sleeve design of the guide rod inside the cross, ensures the stability of the male and female rings when they move in opposite directions. The universal wheels set on the inner wall of the female ring allow the entire cylinder shaft to move easily. At the same time, the limiting plate design on the outer surface of the cylinder effectively prevents the materials from scattering during transportation, ensuring the safety and integrity of the materials.

[0009] Furthermore, handles are fixedly connected to both ends of the bidirectional threaded rod.

[0010] The above solution, with the addition of a handle, makes it easy for users to rotate the bidirectional threaded rod.

[0011] Furthermore, limit plates are fixedly connected to both ends of the outer surface of the cylinder.

[0012] The above solution, through the setting of the limit plate, can effectively prevent materials from scattering to both sides during transportation.

[0013] Furthermore, a set of guide rods is fixedly embedded inside the cross, and both driving plates are slidably sleeved with the two guide rods.

[0014] The above scheme and settings can limit the movement of the female and male rings when rotating the bidirectional threaded rod, ensuring their stable opposite or backward movement.

[0015] Furthermore, the inner wall of the mother ring is fixedly connected with a plurality of connecting blocks arranged in a circle, and each connecting block is threadedly connected with a connecting post inside, and one end of each connecting post is fixedly connected with a caster wheel.

[0016] The above solution, with the addition of casters, facilitates the overall movement of the device.

[0017] Furthermore, the bidirectional threaded rod is a self-locking thread.

[0018] The above solution can effectively prevent the threaded rod from rotating due to vibration during transportation.

[0019] Furthermore, each of the handles is designed with anti-slip features.

[0020] By increasing friction, the above solution allows users to rotate the bidirectional threaded rod stably while preventing hand slippage.

[0021] Furthermore, the cylinder body is coated with a wear-resistant coating.

[0022] The above solutions aim to improve the durability and service life of the cylinder shaft.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This type of roll adhesive tape features a spool design that greatly simplifies the connection process between the male and female rings by employing a trapezoidal insert and a trapezoidal groove. The trapezoidal structure not only provides convenient guidance, allowing the insert to easily slide into the trapezoidal groove, but also ensures the stability of the connection. This design effectively avoids the precision required for the docking of traditional rectangular protrusions and grooves, thus significantly improving the efficiency of loading and unloading. The threaded connection between the bidirectional threaded rod and the drive plate, combined with the sliding sleeve design of the guide rod inside the cross, ensures the stability of the male and female rings when they move in opposite directions. The universal wheels on the inner wall of the female ring allow the entire spool to move easily. At the same time, the limiting plate design on the outer surface of the spool effectively prevents the material from scattering during transportation, ensuring the safety and integrity of the material.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of a roll adhesive tape roller includes a cylindrical body 1 and a male ring 2 and a female ring 3 that are slidably inserted at both ends of the cylindrical body 1. The cylindrical body 1 is coated with a wear-resistant coating to improve the durability and service life of the roller. A cross 4 is fixedly connected to the middle of the inner wall of the cylindrical body 1. A bidirectional threaded rod 5 is rotatably connected to the center of the cross 4. The bidirectional threaded rod 5 is on the same axis as the cylindrical body 1. A driving plate 6 is fixedly connected to the ends of the male ring 2 and the female ring 3 that are close to each other. The two driving plates 6 are threadedly connected to the two ends of the bidirectional threaded rod 5. By rotating the bidirectional threaded rod 5, the male ring 2 can be moved closer to each other and further away. When the male ring 2 and the female ring 3 are close to each other, they can enter the interior of the cylindrical body 1 to achieve the purpose of concealment.

[0033] Please see Figure 1 , Figure 2 and Figure 3 Both ends of the bidirectional threaded rod 5 are fixedly connected to handles 9. The handles 9 make it easy for users to rotate the bidirectional threaded rod 5. Both ends of the outer surface of the cylinder 1 are fixedly connected to limit plates 10. The limit plates 10 can effectively prevent the material from spreading to both sides during transportation. A set of guide rods 11 is fixedly embedded inside the cross 4. The two drive plates 6 are slidably sleeved with the two guide rods 11. With the above settings, the female ring 3 and male ring 2 can be limited when rotating the bidirectional threaded rod 5, ensuring their stable opposite or opposite movement.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The male ring 2 is fixedly connected to a set of circumferentially arranged inserts 7 at the end away from the cylinder 1. Each insert 7 is trapezoidal. The outer surface of the female ring 3 at the end away from the cylinder 1 is provided with a set of circumferentially arranged trapezoidal grooves 8. The trapezoidal arrangement of the inserts 7 and the female ring 3 facilitates the insertions 7 to enter the trapezoidal grooves 8, thus providing a guiding effect.

[0035] Please see Figure 1 , Figure 2 and Figure 3The inner wall of the mother ring 3 is fixedly connected with a plurality of connecting blocks 12 arranged in a circle. Each connecting block 12 is threadedly connected to a connecting post 13. One end of each connecting post 13 is fixedly connected to a caster wheel 14. The caster wheel 14 facilitates the movement of the whole. The bidirectional threaded rod 5 is a self-locking thread, which can effectively prevent the threaded rod from rotating due to vibration during transportation. Each handle 9 is designed with anti-slip properties. By increasing friction, it is easy for the user to rotate the bidirectional threaded rod 5 stably, while preventing the hand from slipping.

[0036] In this embodiment, a roller shaft for a roll of self-adhesive adhesive uses a trapezoidal insert 7 and a trapezoidal groove 8, which greatly simplifies the connection process between the male ring 2 and the female ring 3. The trapezoidal structure not only provides a convenient guiding effect, allowing the insert 7 to easily slide into the trapezoidal groove 8, but also ensures the stability of the connection. This design effectively avoids the precision required when the traditional rectangular protrusion and groove are connected, thus significantly improving the efficiency of loading and unloading. The threaded connection between the bidirectional threaded rod 5 and the drive plate 6, combined with the sliding sleeve design of the guide rod 11 inside the cross 4, ensures the stability of the male ring 2 and the female ring 3 when they move in opposite directions or away from each other. The universal wheel 14 set on the inner wall of the female ring 3 allows the entire roller shaft to move easily. At the same time, the limiting plate 10 design on the outer surface of the cylinder 1 effectively prevents the material from scattering during transportation, ensuring the safety and integrity of the material.

[0037] The working principle of the above embodiment is as follows: First, the cylinder 1, as the core component, has a cross 4 fixedly connected to the middle of its inner wall. A bidirectional threaded rod 5 is rotatably connected to the center of the cross 4. The bidirectional threaded rod 5 coincides with the axis of the cylinder 1, ensuring rotational stability. The male ring 2 and female ring 3 are slidably inserted into both ends of the cylinder 1, and their closest ends are fixedly connected to driving plates 6. These two driving plates 6 are threadedly connected to both ends of the bidirectional threaded rod 5. When the entire assembly needs to be stacked, the user holds the handle 9 and rotates the bidirectional threaded rod 5. Due to the special properties of the bidirectional threaded rod 5... With its special design, the threads at both ends are in opposite directions. Therefore, when rotated, the two driving plates 6 will move towards or away from each other along the thread direction, thereby causing the male ring 2 and the female ring 3 to extend out of the cylinder 1. By docking the male ring 2 with another integral female ring 3, the design of the trapezoidal insert 7 and the trapezoidal groove 8 greatly simplifies the connection process between the male ring 2 and the female ring 3. The trapezoidal structure not only provides a convenient guiding effect, allowing the insert 7 to easily slide into the trapezoidal groove 8, but also ensures the stability of the connection, solving the problem of inconvenient docking in the background technology.
