A test paper binding device Technical Field

[0001] This utility model relates to the field of test paper binding technology, and in particular to a test paper binding device. Background Technology

[0002] To organize scattered exam papers into a neat notebook, making it easier for teachers or students to store them together with other learning materials, preventing the exam papers from being lost or scattered, and facilitating long-term preservation and retrieval, users will use an electric hole punching and binding machine to drill neat holes in the edges of the exam papers to allow the subsequent binding thread, binding clips, etc., to pass through, thus fixing multiple pages of paper together.

[0003] Currently, in the operation of existing electric punching and binding machines, the high-speed rotating blades also carry out paper scraps, resulting in a flying debris phenomenon. These flying debris will scatter on the table, floor, and other surrounding environments. In particular, some small paper scraps are troublesome to clean up, requiring extra time and effort to clean, which affects the cleanliness of the workplace. To address this issue, we propose a test paper binding device. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a test paper binding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Referring to Figures 1-5, a test paper binding device includes a base 1, a sleeve rod 2 fixedly connected to the top of the base 1, and an insertion plate 3 movably inserted inside the sleeve rod 2. A clamp is provided above the base 1, and its principle for fixing the test paper is existing technology. A cutter 4 is mounted on the insertion plate 3, and the high-speed rotation principle of the cutter 4 is existing technology. The up-and-down sliding principle of the insertion plate 3 along the inner wall of the sleeve rod 2 is also existing technology. Through the rotation of the cutter 4, holes can be drilled into the test paper. Its working principle will not be elaborated further here. A handle is provided on the side of the insertion plate 3 to meet the up-and-down movement requirements of the insertion plate 3. This allows the cutting tool 4 to move up and down. A transparent plate 5 is movably fitted on the side of the insertion plate 3, and the upper part of the transparent plate 5 is connected to the connecting rod 7 via a connecting block 6. The connecting rod 7 is vertically inserted into the top of the insertion plate 3, and a fixing block is connected to the top of the connecting rod 7. The bottom of the fixing block is connected to the insertion plate 3 via a spring 8. The top of the insertion plate 3 has an insertion slot that matches the connecting rod 7, thus satisfying the up and down movement requirements of the connecting rod 7 and the transparent plate 5. The transparent plate 5 is made of a material similar to acrylic in the prior art, which makes it easy for the user to see the working status of the cutting tool 4.

[0023] Furthermore, referring to Figures 3 and 4, it can be seen that the bottom of the transparent plate 5 is connected to a rubber strip 9, and the rubber strip 9 and the transparent plate 5 are set in a U-shaped structure. Since the transparent plate 5 is set in a U-shape, it can achieve comprehensive interception of debris, and the rubber strip 9, which is made of rubber material, can protect the bottom of the transparent plate 5.

[0024] Furthermore, referring to Figure 3, it can be seen that there are two sets of connecting blocks 6, and the two sets of connecting blocks 6 are connected by bolts. The bottom of the lower connecting block 6 is fixedly connected to the transparent plate 5, and the top of the upper connecting block 6 is fixedly connected to the bottom of the connecting rod 7. Through the two sets of connecting blocks 6 connected by bolts, it is convenient for workers to disassemble and replace the transparent plate 5 when it reaches the end of its service life.

[0025] Furthermore, referring to Figures 3 and 5, it can be seen that the side of the insertion plate 3 is provided with a support strip 10, and the side of the support strip 10 is evenly distributed with brushes 11. The other end of the brushes 11 abuts against the inner wall of the transparent plate 5. During the up and down movement of the transparent plate 5, the inner wall of the transparent plate 5 can be quickly cleaned through the support strip 10 and the brushes 11 connected to its inner side, so as to effectively prevent debris from always adhering to the inner wall of the transparent plate 5 and affecting the view of the staff.

[0026] Furthermore, as shown in Figure 5, the side of the support bar 10 is connected to the mounting plate 12, and the interior of the mounting plate 12 is connected to the insertion plate 3 by bolts. During use, the mounting plate 12 and the bolts work together to facilitate the replacement of the brush 11 that has reached the end of its service life by the staff.

[0027] Furthermore, referring to Figure 2, a rectangular groove is provided inside the base 1 below the cutter 4, and filter plates 14 are equidistantly connected to the inner wall of the rectangular groove. A receiving groove is provided inside the base 1 below the filter plates 14, and a collection frame 13 is inserted into the inner wall of the receiving groove. Multiple sets of filter plates 14 are provided. When the cutter 4 moves down to drill through the test paper, the cutter 4 will be located in the gap between two sets of filter plates 14, so that the cutter 4 will not damage the filter plates 14. Through the arrangement of filter plates 14, rectangular groove and collection frame 13, the debris can be collected in a concentrated manner to achieve the subsequent rapid dumping of debris. The inner wall of the receiving groove and the outer wall of the collection frame 13 are abutted, thereby meeting the sliding requirements of the collection frame 13.

[0028] Working principle: When using this utility model, the staff can first place the device in a suitable position, and then put the test paper that needs to be punched and bound into the clamp set above the base 1 for clamping and fixing, and then start the operation of the motor inside the insertion plate 3. This allows the cutting tool 4 to rotate at high speed. Then, the operator can push the insertion plate 3 downward so that the cutting tool 4 can be inserted into the test paper to drill holes. When the insertion plate 3 moves downward, the transparent plate 5 on its outer side will abut against the top of the test paper. The connecting block 6 and connecting rod 7 above the transparent plate 5 can meet the requirement that the transparent plate 5 slides along the outer wall of the insertion plate 3 under force, so that the cutting tool 4 can smoothly drill into the test paper to make holes. After drilling, the operator can push the insertion plate 3 upward, and then the operator can release the clamp above the base 1 to pull it out horizontally to remove the drilled test paper. During the process of pulling out the test paper, the user can manually push the remaining debris on the test paper into the rectangular groove, so that it falls into the collection frame 13 through the gap between the filter plates 14 for centralized collection. After a period of use, the operator can pull the collection frame 13 horizontally to remove the collection frame 13 and empty the debris inside. The above is the complete working principle of this utility model.
