Description

Technical Field

[0001] The utility model relates to the technical field of paper box production, and particularly relates to a paper trimming machine provided with a protection device. Background Technique

[0002] During the production process of paper, a trimming device is required to trim the edges and corners of the paper to make the paper reach the specified size. At present, the Chinese patent with the publication number CN213290454U discloses a paper cutter with a protection function, and the technical problems recorded therein state that "some existing paper cutter devices cannot protect the staff. For example, when the stacked paper to be trimmed is offset or uneven, the staff needs to manually trim and level it, which will directly lead to personal danger. Moreover, when the staff places or removes the stacked paper, accidentally starting the power switch of the servo motor will directly cause personal danger."

[0003] It can be seen from the technical problems recorded in the above-mentioned published literature that the existing paper cutting device is not provided with a corresponding protection structure, and when the power switch is accidentally touched and the servo motor is accidentally started, it is easy to cause harm to the operator.

[0004] Therefore, a paper trimming machine provided with a protection device is proposed. Content of the Utility Model

Detailed implementation manners

[0027] The following will describe in detail the implementation manners of the present application in conjunction with the accompanying drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0028] Please refer to Figures 1 to 8As shown in the figure, a paper trimming machine provided with a protection device includes a base 1. At the top of one end of the base 1, a gantry 2 is fixedly installed. An arcuate chute 201 is formed in the inner side wall of the gantry 2. A cutter seat 5 is slidably arranged inside the gantry 2. A paper trimming cutter 6 is fixedly connected to the bottom of the cutter seat 5. Convex sliders 501 are fixedly connected to both ends of the cutter seat 5. The convex sliders 501 are slidably arranged inside the arcuate chute 201. A driving mechanism for driving the paper trimming cutter 6 to move up and down is fixedly installed at the top of the gantry 2. The driving mechanism includes an electric push rod 3. The electric push rod 3 is fixedly installed at the top of the gantry 2. The bottom of the piston rod of the electric push rod 3 is fixedly connected to the top of the cutter seat 5. In order to further improve the stability of the up and down movement of the paper trimming cutter 6, a guide rod 4 is fixedly installed at the top of the cutter seat 5. The upper end of the guide rod 4 slidably penetrates through the top of the gantry 2.

[0029] Wherein, a protection component 7 for preventing the accidental fall of the paper trimming cutter 6 is arranged on one side of the gantry 2. The protection component 7 includes a push rod 701. An assembly groove 202 is formed inside one end of the gantry 2. One end of the push rod 701 slidably penetrates through the gantry 2 and is fixedly connected to a connecting block 707. A plug rod 708 is fixedly connected to the end of the connecting block 707 away from the push rod 701. A groove is formed on one side of one of the convex sliders 501. A plurality of tooth grooves 5011 are equidistantly formed on the inner wall of the groove from top to bottom. After the end of the plug rod 708 away from the connecting block 707 slidably extends into the arcuate chute 201, it can be stuck in the tooth groove 5011. A handle 704 is installed at the end of the convex slider 501 away from the connecting block 707. Wherein, a spring 706 is arranged inside the assembly groove 202. The spring 706 is sleeved on the push rod 701. A convex block 702 is fixedly connected to the end of the push rod 701 close to the handle 704. The convex block 702 is slidably arranged inside the arcuate chute 201. One end of the spring 706 abuts against one side of the assembly groove 202, and the other end of the spring 706 abuts against one side of the convex block 702. In order to ensure that the plug rod 708 can be stably inserted into and withdrawn from the tooth groove 5011, a limiting chute communicated with the assembly groove 202 is formed on one side of the gantry 2. A limiting block 703 is fixedly connected to the surface of the convex block 702. The limiting block 703 is slidably arranged inside the limiting chute.

[0030] By adopting the above technical solution, during use, when trimming the paper is required, press the handle 704, so that the push rod 701 moves into the interior of the assembly groove 202, and then the connecting block 707 drives the plug rod 708 to move out of the tooth groove 5011. At this time, the plug rod 708 releases the locking of the convex slider 501. Then start the electric push rod 3, so that the piston rod of the electric push rod 3 extends, and then drives the paper trimming cutter 6 to move downward through the tool holder 5. At this time, release the handle 704, and the downward moving paper trimming cutter 6 can trim the paper. After the trimming operation is completed, the electric push rod 3 drives the paper trimming cutter 6 to move upward through the tool holder 5 for reset. At this time, the plug rod 708 is reinserted into the tooth groove 5011 under the elastic force of the spring 706 to realize the automatic locking of the paper trimming cutter 6.

[0031] Further, in order to facilitate the adjustment of the trimming length, a baffle 9 is slidably arranged at one end of the base 1, an adjusting rod 10 is slidably arranged inside the base 1, the upper end of the adjusting rod 10 is fixedly connected to one side of the baffle 9, and a handle screw 8 for locking the adjusting rod 10 is threadedly installed on one side of the base 1. By moving the position of the baffle 9, the distance between the baffle 9 and the paper trimming cutter 6 can be adjusted. Then attach one side of the paper to one side of the baffle 9, and thus the paper trimming cutter 6 can accurately trim the paper.

[0032] The above description shows and describes several preferred embodiments of the present invention. However, as mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the inventive concept described herein through the above teachings or the technology or knowledge in related fields. And any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
