Description

Technical Field

[0001] This utility model relates to the field of roller pressing and pasting technology, specifically to a roller pressing and pasting device for sealing labels on test paper bags. Background Technology

[0002] The exam paper bag seal is an important component of the exam security management system. It is mainly used to seal the exam paper bag to ensure that the exam papers are not illegally opened or tampered with during the entire process of transportation, storage, and marking. Through one-time adhesive or special material design, it leaves an irreversible mark after being opened. Some seals integrate barcodes, QR codes, or candidate information fields and are bound to the exam paper bag to prevent substitution. Candidates and invigilators are required to sign the seal to clarify the responsibilities of each person at each stage.

[0003] However, existing roller-pressing adhesive devices require users to hold the roller and press the sealing label onto the label during actual use. Prolonged operation can cause arm pain and increase the user's workload. To address this issue, a roller-pressing adhesive device for sealing labels on test paper bags is provided.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a test paper bag sealing label roller pressing and pasting device, including a base 1, a frame 2 at the top of the base 1, a sliding component in the inner cavity of the frame 2, a support 3 at the front end of the sliding component, an elastic component on the support 3, a fixed frame 4 at the bottom of the elastic component, and a rotating roller 5 rotatably connected to the inner cavity of the fixed frame 4 via a bearing. The sliding component drives the support 3, the elastic component, the fixed frame 4, and the rotating roller 5 to repeatedly press and paste the test paper bag at the top of the base 1, thereby achieving the purpose of automatic sealing label roller pressing and pasting. This solves the problem that in the actual use of existing roller pressing and pasting devices, users need to hold the roller 8 to press and paste the sealing label, which can cause arm pain and increase the workload of users after a long period of operation. By setting the elastic component, the fixed frame 4 and the rotating roller 5 can always be subjected to a downward force, thereby keeping the rotating roller 5 in close contact with the test paper bag sealing label, improving the stability of the device during use.

[0021] In this embodiment, the sliding assembly includes a motor 6, a rotating column 7, a roller 8, a slide groove 9, a fixing plate 10, a limiting component, a sliding plate 13, and a slider 14. The motor 6 is located at the right end of the frame 2, and its output end extends into the inner cavity of the frame 2. One end of the rotating column 7 is rotatably connected to the left side of the inner cavity of the frame 2 via a bearing, and the other end of the rotating column 7 is fixedly connected to the output end of the motor 6. The roller 8 is fixedly sleeved on the outer wall of the rotating column 7, and the slide groove 9 is formed on the outer wall of the roller 8. The fixing plate 10 is located on the rear side of the inner cavity of the frame 2, the limiting component is located on the front side of the fixing plate 10, and the sliding plate 13 is located on the... The front end of the limiting component is fixedly connected to the bracket 3. The slider 14 is slidably embedded in the inner cavity of the slide groove 9 and fixedly connected to the bottom end of the slide plate 13. The motor 6 is started, so that the motor 6 drives the slide groove 9 to rotate through the rotating column 7 and the roller 8. Since the slide groove 9 is spiral and connected end to end, when the slide groove 9 rotates, the slider 14 can drive the slide plate 13 to slide back and forth horizontally under the limiting action of the limiting groove 11 and the limiting block 12. This causes the bracket 3 to drive the fixed cylinder 15, the moving rod 16, the fixed frame 4 and the rotating roller 5 to slide back and forth horizontally to repeatedly roll the test paper bag seal.

[0022] In this embodiment, the slide groove 9 is spiral-shaped and connected end to end. When the slide groove 9 rotates, the slider 14 can drive the slide plate 13 to slide back and forth in the horizontal direction under the limiting action of the limiting groove 11 and the limiting block 12.

[0023] In this embodiment, the limiting component includes a limiting groove 11 and a limiting block 12. The limiting groove 11 is opened at the front end of the fixed plate 10. The limiting block 12 is slidably embedded in the inner cavity of the limiting groove 11 and fixedly connected to the slide plate 13. Under the limiting action of the limiting groove 11 and the limiting block 12, the slide plate 13 can always slide along a straight line.

[0024] In this embodiment, the inner cavity of the limiting groove 11 and the outer wall of the limiting block 12 are adapted to each other and are both in the shape of a "T". This allows one end of the limiting block 12 to always remain embedded in the inner cavity of the limiting groove 11, which improves the stability of the limiting component during use and prevents the limiting block 12 from dislodging from the inner cavity of the limiting groove 11, causing the slide plate 13 and the slider 14 at the bottom of the slide plate 13 to move out of the inner cavity of the slide groove 9.

[0025] In this embodiment, the elastic component includes a fixed cylinder 15, a movable rod 16, a limiting plate 17, a spring 18, and a connecting assembly. The fixed cylinder 15 is fixedly inserted into the bracket 3. The movable rod 16 is slidably inserted into the inner cavity of the fixed cylinder 15. The limiting plate 17 is disposed at the top end of the movable rod 16, and the bottom end of the movable rod 16 is fixedly connected to the top end of the fixed frame 4. The spring 18 is sleeved on the outer wall of the movable rod 16, and the upper and lower ends of the spring 18 are fixedly connected to the bracket 3 and the fixed frame 4, respectively. The connecting assembly is disposed in the inner cavity of the fixed cylinder 15 and is connected to the movable rod 16. The outer wall of the moving rod 16 is fixedly connected. Under the elastic force of the spring 18, the fixed frame 4 is always subjected to a downward force, thereby ensuring that the rotating roller 5 is always in close contact with the sealing tag. Through the arrangement of the fixed cylinder 15 and the moving rod 16, the fixed frame 4 is always subjected to a vertical downward force. It also allows the fixed frame 4 and the rotating roller 5 to rotate synchronously when the bracket 3 slides. Under the action of the connecting component, the situation where the moving rod 16, the fixed frame 4, and the rotating roller 5 rotate around the center of the fixed cylinder 15 can be prevented.

[0026] In this embodiment, the connecting assembly includes a connecting groove 19 and a connecting block 20. The connecting groove 19 is formed on the inner wall of the fixed cylinder 15, and the connecting block 20 is slidably embedded in the inner cavity of the connecting groove 19. Under the joint action of the connecting block 20 and the connecting groove 19, the moving rod 16, the fixed frame 4, and the rotating roller 5 can be prevented from rotating around the center of the fixed cylinder 15. The inner cavity of the connecting groove 19 and the outer wall of the connecting block 20 are adapted to each other and are both in the shape of a "T". This ensures that one end of the connecting block 20 is always embedded in the inner cavity of the connecting groove 19, thereby improving the stability of the connecting assembly during use.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
