Description

Technical Field

[0001] This utility model relates to the field of test paper bag processing technology, specifically to an automatic corner-folding device for stamping test paper bags. Background Technology

[0002] Exam paper bags are an indispensable tool in the examination process, mainly used to seal exam papers, answer sheets, and other related examination materials. They not only bear the responsibility of protecting these valuable documents from damage, but also ensure the standardization and transparency of the entire examination process. By using specialized exam paper bags, it is possible to effectively prevent exam papers from being lost or illegally tampered with during transmission, thereby maintaining the principle of fairness and impartiality in the examination. To adapt to the needs of use in different environments, exam paper bags are usually made of high-quality materials, possessing good durability and waterproof performance.

[0003] In existing technologies, after the test paper bags are stamped, they need to be folded at the corners to ensure their integrity and security. However, this is usually done manually. Manual folding requires operators to process each test paper bag one by one, which is time-consuming and highly repetitive. Especially when dealing with a large number of test paper bags, it will significantly reduce the overall work efficiency. If the operation is improper or negligent during the manual folding process, the test paper bags may be damaged or not sealed properly, thereby increasing the risk of test papers being lost or tampered with. In addition, human factors may also cause the sealing label to be not firmly attached or to be misaligned, further reducing the security of the test papers. Utility Model Content

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 5 This utility model provides a technical solution for an automatic corner-folding device for stamping test paper bags:

[0025] In the embodiments of this utility model, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The device includes a box body 1, inside which a corner-folding device 2 is installed. The corner-folding device 2 includes a mounting bracket 201 installed on the inner wall of the box body 1. The top of the mounting bracket 201 is rotatably connected to two first mounting plates 202. The opposite sides of the two first mounting plates 202 are each connected to a first rotating shaft 203. One end of the first rotating shaft 203 is connected to a second mounting plate 204, and the other end of the first rotating shaft 203 is connected to a second rotating shaft 205. One end of the second rotating shaft 205 is connected to a first connecting rod 206. The opposite sides of the two first connecting rods 206 are each connected to a third rotating shaft 207. The ends of the two second mounting plates 204 away from the first rotating shafts 203 are each rotatably connected to a second connecting rod 208. The bottom end of each second connecting rod 208 is connected to a fourth rotating shaft 209. The outer wall of the third rotating shaft 207 is connected to a fixing block 210, and the bottom end of the fixing block 210 is connected to a corner-folding plate 211.

[0026] It should be noted that after the corner folding plate 211 rotates 180 degrees, it fits into the placement plate 6, thus straightening the corners of the test paper bag where they need to be folded. The cooperation of mechanical parts avoids errors caused by manual operation, improves the stability of the work and ensures the efficiency of the work.

[0027] See Figure 2 , Figure 5 A limiting device 3 is installed on one side of the mounting bracket 201. The limiting device 3 includes a first bevel gear 301 installed on one side of the mounting bracket 201, a second bevel gear 302 connected to one side of the first bevel gear 301, a rotating shaft 303 installed in the middle of the second bevel gear 302, a third bevel gear 304 installed at the end of the rotating shaft 303 away from the second bevel gear 302, a fourth bevel gear 305 connected to the outer wall of the third bevel gear 304, and a limiting rod 306 connected to the bottom end of the fourth bevel gear 305.

[0028] It should be noted that: through the linkage between the limiting device 3 and the corner folding device 2, when the mounting frame 201 is rotated and started, the limiting device 3 will cause the limiting rod 306 to rotate according to the rotation of the mounting frame 201, thereby controlling the test paper bag to a 90-degree limit and preventing the test paper bag from folding incorrectly due to instability.

[0029] See Figure 1 The outer wall of the box body 1 is provided with a storage groove 4. The inner left side wall of the storage groove 4 is provided with a slot. The width of the slot is the same as the width of the limiting rod 306, and the shape of the slot is adapted to the limiting rod 306. A control panel 5 is installed on one side of the outer wall of the box body 1. A placement plate 6 is fixedly connected to the inner bottom wall of the storage groove 4. The shape of the placement plate 6 is adapted to the shape of the corner plate 211.

[0030] It should be noted that the combination of the placement plate 6 and the corner folding plate 211 can make the appearance of the test paper bag more regular after the corner is folded.

[0031] See Figure 1 The corner plate 211 and the placement plate 6 are provided with anti-slip pads on their top outer walls. The anti-slip pads are made of rubber and are adapted to the shape of the corner plate 211 and the placement plate 6.

[0032] It should be noted that the anti-slip mat is made of rubber, which gives it good elasticity and wear resistance. The rubber anti-slip mat can effectively increase the friction with the paper, thereby preventing the paper from slipping and improving the stability of the equipment during operation.

[0033] Working principle: After the two first mounting plates 202 installed on opposite sides of the inner wall of the mounting bracket 201 rotate, they drive the second rotating shaft 205 connected to one side to pull the first connecting rod 206 to start rotating. After the first connecting rod 206 rotates, it drives the third rotating shaft 207 fixedly connected to the opposite side of the two first connecting rods 206. The outer wall of the third rotating shaft 207 is fitted with a fixing block 210. After the third rotating shaft 207 rotates, the fixing block 210 will rotate accordingly according to the rotation amplitude of the third rotating shaft 207. The rotation of the fixing block 210 drives the angle plate 211, and the angle plate 211 and the storage groove... After the placement plate 6, which is fixedly connected to the inner bottom wall, is flipped and attached, when the mounting frame 201 rotates, the first bevel gear 301 installed at one end of the mounting frame 201 rotates with the mounting frame 201, driving the meshing second bevel gear 302 to rotate. Then, the third bevel gear 304 installed at the other end of the rotating shaft 303 will drive the meshing fourth bevel gear 305 according to the rotation of the second bevel gear 302, causing the limiting rod 306 fixedly connected to the bottom end of the fourth bevel gear 305 to undergo a 90-degree angle adjustment. After limiting the position where the test paper bag needs to be pressed, the corner folding plate 211 and the placement plate 6 fold the corner of the test paper bag.
