Description
Technical Field
[0001] This utility model belongs to the field of binding equipment technology, specifically an octavo test paper binding device. Background Technology
[0002] When using test papers, there are many students in the same classroom. After the exam, the teachers need to collect the test papers. In order to ensure that the test papers are not easily lost and are carried together, binding equipment is generally used to bind the test papers together.
[0003] Current exam paper binding equipment typically consists of a base, a fixed frame fixedly connected to the top of the base, a first cylinder fixedly connected to the top of the fixed frame, a punching head fixedly connected to the output end of the first cylinder, a mounting groove on the top of the base, an electric telescopic rod fixedly connected to the bottom wall of the mounting groove, an ejector block fixedly connected to the output end of the electric telescopic rod, a second cylinder fixedly connected to the top of the base, and a limiting plate fixedly connected to the output end of the second cylinder. The binding line is placed on the base, and the prepared exam paper is placed on the ejector block of the base. The four second cylinders are then activated, causing the four limiting plates to gradually approach and clamp the exam paper. Simultaneously, the second cylinders can be activated to drive the punching head to punch holes in the exam paper. Then, the electric telescopic rod, in conjunction with the ejector block, pushes out the binding block via the binding line, thus binding the exam paper.
[0004] In large-scale examinations, the number of exam papers that need to be bound is usually large. However, the method of using multiple cylinders to drive multiple clamping plates to clamp and limit the exam papers requires separate limiting of the exam papers in multiple directions, which is a cumbersome process and affects the binding efficiency. Therefore, an eight-page exam paper binding device is proposed to address the above problems. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and solve problem 111, an octavo exam paper binding device is proposed.
[0006] The technical solution adopted by this utility model to solve its technical problem is: an eight-page test paper binding device of this utility model, including a binding base; a binding machine is installed on the top of the binding base, and a fixing plate is fixedly connected to the top of the binding base;
[0007] The binding base is equipped with a limiting mechanism, which includes a positioning groove on the top of the binding base. A double-threaded rod is rotatably connected to one side of the inner wall of the positioning groove. Both ends of the outer wall of the double-threaded rod are threaded with transmission blocks. The top of the transmission block extends out of the positioning groove and is fixedly connected to a limiting plate. A transmission groove is opened on the side of the limiting plate away from the binding machine. A fixing groove is opened on the top of the binding base. A rack is fixedly connected to the inner bottom wall of the fixing groove. A transmission rod is rotatably connected to the inner top wall of the transmission groove. The bottom end of the transmission rod passes through the limiting plate and is fixedly connected to a gear. The gear meshes with the rack. A limiting block is fixedly connected to one side of the outer wall of the transmission rod. Through the setting of the limiting mechanism and the fixing plate, the limiting operation steps can be simplified while ensuring the limiting of the test paper, thereby improving the binding efficiency.
[0008] Preferably, a pressing groove is provided on one side of the limiting plate, and a pressing block is slidably connected in the pressing groove. The top of the pressing block is elastically connected to the inner wall of the pressing groove by a spring. A first magnetic block is fixedly connected to the top of the pressing block, and a second magnetic block is fixedly connected to the top of the binding base. By setting up the pressing block, the first magnetic block, the second magnetic block and the spring, it is convenient to automatically press the test paper and avoid the test paper from moving upward when the punch head is pulled out of the test paper.
[0009] Preferably, an auxiliary groove is provided on one side of the pressing block, and an auxiliary wheel is rotatably connected to the inner wall of the auxiliary groove via a rotating shaft. The auxiliary groove and the auxiliary wheel allow the auxiliary wheel to replace the pressing block in contact with the test paper, preventing the limiting block from excessively pulling the test paper when the limiting block is pulled open, thus avoiding damage to the test paper. This also allows the auxiliary wheel to slide on the test paper, reducing friction.
[0010] Preferably, a knob is fixedly connected to one end of the double-ended threaded rod located on the outside. The outer wall of the knob is provided with anti-slip texture. The knob allows the double-ended threaded rod to rotate easily by rotating the knob.
[0011] Preferably, a baffle is fixedly connected to the inner wall of the positioning groove, and an auxiliary plate is fixedly connected to the side of the limiting plate away from the fixed plate. By setting the baffle, the debris generated by drilling can be prevented from entering the positioning groove. The positioning groove is shielded by the limiting plate and the auxiliary plate to prevent the debris from affecting the rotation of the double-ended threaded rod and the movement of the transmission block.
[0012] Preferably, the binding base has a sliding groove on its front side, and the outer wall of the limiting plate is provided with a rubber pad. The sliding groove allows the test paper to be easily removed by inserting a finger into it and lifting it up.
[0013] Preferably, the bottom of the binding base is provided with anti-slip protrusions, and the outer wall of the fixing plate is provided with rubber pads. The anti-slip protrusions at the bottom of the binding base increase the friction of the binding base, and the rubber pads on the outer wall of the fixing plate ensure the protection of the test paper.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model provides an octavo exam paper binding device. Through the setting of a limiting mechanism and a fixing plate, the limiting operation steps can be simplified while ensuring the limiting of the exam paper, thereby improving the binding efficiency. Specifically, the binding thread is placed on the ejector block on the binding base, so that part of the binding thread is embedded in the ejector groove. After the exam paper to be bound is initially arranged, it is placed on the binding base and one end abuts against the fixing plate. By rotating the double-headed threaded rod, one side of the limiting plate abuts against one side of the exam paper. The limiting block rotates and abuts against the side of the exam paper away from the fixing plate. The two limiting plates, two limiting blocks and the fixing plate work together to quickly limit the exam paper, simplifying the operation steps in the limiting process. The binding machine is operated to punch holes in the limited exam paper. The cylinder is activated to make the ejector block pass through the binding hole and push the binding thread out of the binding hole of the exam paper, so as to facilitate the knotting and binding of the exam paper.
[0016] 2. This utility model provides an octavo exam paper binding device. Through the arrangement of a pressing block, a first magnetic block, a second magnetic block, and a spring, it facilitates automatic pressing of the exam paper, preventing the exam paper from being pulled upwards when the punching head is pulled out. Specifically, as the limiting plate moves, it simultaneously moves the first magnetic block. When the limiting plate is about to approach the exam paper, the first magnetic block will misalign with the second magnetic block, meaning the first magnetic block will move away from above the second magnetic block. The opposite sides of the first and second magnetic blocks are set to be at the same level. When the first magnetic block is above the second magnetic block, the repulsive force between the two magnetic blocks will push the first magnetic block upwards. The first magnetic block drives the pressing block upwards and applies pressure to the spring. When the first and second magnetic blocks misalign, the repulsive force disappears, and under the pressure of the spring, the pressing block quickly descends and presses the exam paper, preventing the exam paper's pull strap from being pulled up when the punching head is pulled upwards.

[0024] 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.
[0025] Specific implementation examples are given below.
[0026] Please see Figures 1-4 This utility model provides an octavo test paper binding device, including a binding base 1; a binding machine 2 is installed on the top of the binding base 1, and a fixing plate 3 is fixedly connected to the top of the binding base 1.
[0027] A limiting mechanism 4 is provided on the binding base 1. The limiting mechanism 4 includes a positioning groove on the top of the binding base 1. A double-threaded rod 41 is rotatably connected to one side of the inner wall of the positioning groove. Both ends of the outer wall of the double-threaded rod 41 are threadedly connected to transmission blocks 42. The top of the transmission block 42 extends out of the positioning groove and is fixedly connected to a limiting plate 43. A transmission groove is provided on the side of the limiting plate 43 away from the binding machine 2. A fixing groove is provided on the top of the binding base 1. A rack 44 is fixedly connected to the inner bottom wall of the fixing groove. A transmission rod is rotatably connected to the inner top wall of the transmission groove. The bottom end of the transmission rod passes through the limiting plate 43 and is fixedly connected to a gear 45. Wheel 45 meshes with rack 44, and a limit block 46 is fixedly connected to one side of the outer wall of the transmission rod. During operation, the binding machine 2 is the existing punching and binding machine 2 used for exam papers, so it will not be described in detail. This equipment is suitable for binding A4-sized documents. The top of the binding base 1 has an installation groove, and a cylinder is fixedly connected to the inner bottom wall of the installation groove. An ejector block is fixedly connected to the output end of the cylinder, and an ejector groove is opened on the top of the ejector block. The ejector block and the cylinder cooperate to eject the binding thread from the binding hole of the exam paper after the binding machine 2 has punched holes, facilitating the binding of the exam paper. This is achieved through the limit mechanism 4. The setting of the fixing plate 3 can simplify the limiting operation steps and improve binding efficiency while ensuring the limiting of the test paper. Specifically, the binding thread is placed on the ejector block on the binding base 1, so that part of the binding thread is embedded in the ejector groove. After the test paper to be bound is initially arranged, it is placed on the binding base 1 with one end abutting against the fixing plate 3. Then, the outer end of the double-ended threaded rod 41 is rotated, causing the two transmission blocks 42 on it to move closer together. The two transmission blocks 42 drive the two limiting plates 43 to move closer together until one side of the limiting plate 43 abuts against one side of the test paper. Simultaneously, during this process, the limiting plate 43 drives the gear 45. The synchronous movement and the rack 44 cause the gear 45 to rotate. The gear 45 drives the limiting block 46 to rotate through the transmission rod. That is, when the limiting plate 43 abuts against one side of the test paper, the limiting block 46 rotates and abuts against the side of the test paper away from the fixing plate 3. Then, the two limiting plates 43, the two limiting blocks 46 and the fixing plate 3 work together to quickly limit the test paper and simplify the operation steps in the limiting process. Then, the binding machine 2 can be operated to punch holes in the limited test paper. After the punching is completed, the cylinder is started to make the ejector block pass through the binding hole and push the binding thread out from the binding hole of the test paper so as to tie and bind the test paper.
[0028] Furthermore, such as Figure 1 and Figure 4As shown, a pressing groove is provided on one side of the limiting plate 43, and a pressing block 5 is slidably connected in the pressing groove. The top of the pressing block 5 is elastically connected to the inner wall of the pressing groove through a spring 7. A first magnetic block 6 is fixedly connected to the top of the pressing block 5, and a second magnetic block 8 is fixedly connected to the top of the binding base 1. During operation, the arrangement of the pressing block 5, the first magnetic block 6, the second magnetic block 8, and the spring 7 facilitates automatic pressing of the test paper, preventing the test paper from being pulled upwards when the punching head is pulled out. Specifically, as the limiting plate 43 moves, it simultaneously moves the first magnetic block 6. When the limiting plate 43 is about to approach the test paper, the first magnetic block 6 will be misaligned with the second magnetic block 8, meaning the first magnetic block 6 will move away from above the second magnetic block 8. The opposite sides of the first magnetic block 6 and the second magnetic block 8 are set to be at the same level. When the first magnetic block 6 is above the second magnetic block 8, the repulsive force between the two magnetic blocks will push the first magnetic block 6 upwards. The first magnetic block 6 drives the pressing block 5 to move upwards and applies pressure to the spring 7. When the first magnetic block 6 and the second magnetic block 8 are misaligned, the repulsive force disappears, and under the pressure of the spring 7, the pressing block 5 quickly descends and presses the test paper, preventing the test paper pull strap from being pulled up when the punching head is pulled upwards.
[0029] Furthermore, such as Figure 4 As shown, an auxiliary groove is provided on one side of the pressing block 5, and an auxiliary wheel 9 is rotatably connected to the inner wall of the auxiliary groove via a rotating shaft. During operation, the auxiliary groove and the auxiliary wheel 9 allow the auxiliary wheel 9 to replace the pressing block 5 in contact with the test paper, preventing the limiting block 46 from excessively pulling the test paper when the limiting block is pulled open, thus avoiding damage to the test paper. This also allows the auxiliary wheel 9 to slide on the test paper, reducing friction.
[0030] Furthermore, such as Figure 1 and Figure 2 As shown, a knob 10 is fixedly connected to one end of the double-ended threaded rod 41 located on the outside. The outer wall of the knob 10 is provided with anti-slip texture. During operation, the knob 10 facilitates the rotation of the double-ended threaded rod 41 by turning the knob 10.
[0031] Furthermore, such as Figure 1 and Figure 2 As shown, a baffle 11 is fixedly connected to the inner wall of the positioning groove, and an auxiliary plate is fixedly connected to the side of the limiting plate 43 away from the fixed plate 3. During operation, the baffle 11 prevents debris generated during drilling from entering the positioning groove. Together with the limiting plate 43 and the auxiliary plate, the positioning groove is shielded to prevent debris from affecting the rotation of the double-ended threaded rod 41 and the movement of the transmission block 42.
[0032] Furthermore, such as Figure 1 As shown, the binding base 1 has an actuation groove 12 on its front side, and a rubber pad is provided on the outer wall of the limiting plate 43. During operation, the actuation groove 12 allows the test paper to be easily lifted by inserting a finger into the actuation groove 12 to remove the test paper.
[0033] Furthermore, such as Figure 1 As shown, the bottom of the binding base 1 is provided with anti-slip protrusions, and the outer wall of the fixing plate 3 is provided with rubber pads. During operation, the anti-slip protrusions at the bottom of the binding base 1 increase the friction of the binding base 1, and the rubber pads on the outer wall of the fixing plate 3 ensure the protection of the test paper.
[0034] Working principle: The binding thread is placed on the ejector block on the binding base 1, so that the binding thread is partially embedded in the ejector groove. After the test paper to be bound is initially arranged, it is placed on the binding base 1 with one end abutting against the fixing plate 3. Then, the double-ended threaded rod 41 is rotated at the outer end, which drives the two transmission blocks 42 on it to move closer to each other. The two transmission blocks 42 drive the two limiting plates 43 to move closer to each other until one side of the limiting plate 43 abuts against one side of the test paper. At the same time, during this process, the limiting plate 43 drives the gear 45 to move synchronously and cooperates with the rack 44 to make the gear 45 rotate. The gear 45 drives the limiting block 46 to rotate through the transmission rod. That is, when the limiting plate 43 abuts against one side of the test paper, the limiting block 46 rotates and abuts against the side of the test paper away from the fixing plate 3. The two limiting plates 43, the two limiting blocks 46, and the fixing plate 3 work together to quickly limit the test paper and simplify the operation steps in the limiting process. Then, the binding machine 2 can be operated to punch holes in the limited test paper. After the punching is completed, the cylinder is activated to make the ejector block pass through the binding hole and push the binding thread out of the binding hole of the test paper, so as to tie and bind the test paper. When the first magnetic block 6 is above the second magnetic block 8, the repulsive force between the two magnetic blocks will push the first magnetic block 6 upward. The first magnetic block 6 drives the pressing block 5 to move upward and apply pressure to the spring 7. When the first magnetic block 6 and the second magnetic block 8 are misaligned, the repulsive force disappears. Under the pressure of the spring 7, the pressing block 5 quickly descends and presses the test paper to prevent the test paper strap from being pulled up when the punching block is pulled up.
[0035] 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 illustrative of the principles of this 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.
