A paper pre-folding and slitting apparatus

Abstract

This utility model discloses a paper pre-folding and slitting device. It includes a worktable, a receiving frame fixedly mounted on the top of the worktable, and a paper placement seat fixedly mounted inside the receiving frame on the top of the worktable. Limiting rods are fixedly mounted on both the left and right sides of the top of the inner cavity of the receiving frame. This paper pre-folding and slitting device pre-folds the paper by placing it on top of the paper placement seat, allowing the triangular pressing block, two baffles, and the paper placement seat to cooperate. After pre-folding, the cutting blade is driven downwards. During the downward movement of the cutting blade, it pushes the two baffles away from each other until they contact the paper, completing the cutting and making the cutting more precise and reliable. After cutting, the cutting blade is moved back to its initial position. Simultaneously, under the elastic action of a torsion spring, the two baffles contact each other and return to their initial position, shielding the cutting blade and preventing external impurities from splashing onto its surface, thus protecting the cutting blade and extending its service life.

Description

Technical Field

[0001] This utility model relates to the field of paper slitting technology, specifically to a paper pre-folding and slitting device. Background Technology

[0002] Against the backdrop of the rapid development of the printing and packaging industry, with the surge in market demand for personalized, small-batch orders and the urgent need for efficient and automated production, traditional paper slitting processes face challenges such as insufficient precision, low efficiency, and poor flexibility. To address this pain point, paper pre-folding slitting devices have emerged, which simultaneously complete the pre-folding action of paper during the slitting process, significantly reducing subsequent processing steps.

[0003] Existing paper pre-folding and slitting devices are difficult to perform efficient pre-folding before slitting the paper, which makes direct cutting prone to errors. Furthermore, the cutting blade is directly exposed to the external environment after cutting, making it prone to damage and affecting its service life. Therefore, it is necessary to provide a paper pre-folding and slitting device to solve the above-mentioned technical problems. Utility Model Content

[0004] (a) Technical problems to be solved To overcome the shortcomings of existing technologies, a paper pre-folding and slitting device is proposed to solve the problems of difficulty in efficiently pre-folding paper before slitting, which leads to errors in direct cutting, and the cutting blade being directly exposed to the external environment after cutting, which is prone to damage and affects service life.

[0005] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a paper pre-folding and slitting device, including a worktable, a receiving frame fixedly installed on the top of the worktable, a paper placement seat located inside the receiving frame fixedly installed on the top of the worktable, limit rods fixedly installed on the left and right sides of the top of the inner cavity of the receiving frame, a top plate slidably sleeved between the two limit rods, a first electric telescopic rod fixedly installed in the middle of the top of the inner cavity of the receiving frame, the bottom of the first electric telescopic rod fixedly connected to the middle of the top of the top plate, and a triangular pressing block mechanism fixedly installed at the bottom of the top plate.

[0006] Furthermore, the bottom of each of the limiting rods is fixedly connected to the top of the workbench, and support legs are fixedly provided at the four corners of the bottom of the workbench. Baffles are fixedly provided between the front walls and the rear walls of the receiving frame, and an intelligent control panel is fixedly provided at the front end of the front baffle.

[0007] Furthermore, the triangular pressing block mechanism includes a triangular pressing block, the top of which is fixedly connected to the bottom of the top plate, and a receiving groove is provided in the middle of the bottom of the triangular pressing block. A second electric telescopic rod is fixedly installed at both the front and rear ends of the top of the receiving groove.

[0008] Furthermore, a cutting blade is fixedly installed between the bottoms of the two second electric telescopic rods, and a rotating shaft is rotatably installed between the front and rear walls on the left and right sides of the lower part of the receiving groove, with a support rod fixedly sleeved on the front and rear parts of each rotating shaft.

[0009] Furthermore, a baffle is fixedly provided between the bottoms of the two support rods, and torsion springs are sleeved on the front and rear parts of the rotating shaft. The torsion springs are located between the corresponding support rod and the inner wall of the receiving groove, and the two baffles are arranged symmetrically.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: By placing the paper to be cut on the top of the paper holder, the triangular pressing block and the two baffles cooperate with the paper holder to achieve pre-folding of the paper. After pre-folding, the cutting blade is driven to move down.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] A paper pre-folding and slitting device includes a workbench 1, a receiving rack 2 fixedly mounted on the top of the workbench 1, a paper placement seat 3 fixedly mounted on the top of the workbench 1 inside the receiving rack 2, limit rods 4 fixedly mounted on the left and right sides of the top of the inner cavity of the receiving rack 2, a top plate 5 slidably sleeved between the two limit rods 4, a first electric telescopic rod 6 fixedly mounted in the middle of the top of the inner cavity of the receiving rack 2, the bottom of the first electric telescopic rod 6 fixedly connected to the middle of the top of the top plate 5, and a triangular pressing block mechanism 7 fixedly mounted on the bottom of the top plate 5.

[0015] In this embodiment, the bottom of each limiting rod 4 is fixedly connected to the top of the workbench 1, and support legs 8 are fixedly provided at the four corners of the bottom of the workbench 1. Baffles 9 are fixedly provided between the front wall and the rear wall of the receiving frame 2, and an intelligent control panel 10 is fixedly provided at the front end of the front baffle 9.

[0016] In this embodiment, the triangular pressing block mechanism 7 includes a triangular pressing block 71. The top of the triangular pressing block 71 is fixedly connected to the bottom of the top plate 5. A receiving groove 72 is provided in the middle of the bottom of the triangular pressing block 71. A second electric telescopic rod 73 is fixedly provided at the front and rear ends of the top of the receiving groove 72.

[0017] In this embodiment, a cutting blade 74 is fixedly installed between the bottoms of the two second electric telescopic rods 73, and a rotating shaft 75 is rotatably installed between the front and rear walls on the left and right sides of the lower part of the receiving groove 72. A support rod 76 is fixedly sleeved on the front and rear parts of each rotating shaft 75.

[0018] In this embodiment, a baffle 77 is fixedly provided between the bottoms of the two support rods 76, and torsion springs 78 are sleeved on the front and rear parts of the rotating shaft 75. The torsion springs 78 are located between the corresponding support rod 76 and the inner wall of the receiving groove 72, and the two baffles 77 are arranged symmetrically.

[0019] By placing the paper to be cut on top of the paper placement seat 3, the triangular pressing block 71 and the two baffles 77 cooperate with the paper placement seat 3 to achieve pre-folding of the paper. After pre-folding, the cutting blade 74 is driven to move downward. During the downward movement of the cutting blade 74, it will push the two baffles 77 away from each other until they come into contact with the paper, thus completing the cutting of the paper. This makes the cutting more precise and reliable. After the cutting is completed, the cutting blade 74 is moved upward to the initial position. At the same time, under the elastic action of the torsion spring 78, the two baffles 77 come into contact and return to the initial position, covering the cutting blade 74 and preventing external impurities from splashing onto the surface of the cutting blade 74, thus protecting the cutting blade 74 and extending its service life.

[0020] Working principle: In use, place the paper to be cut on top of the paper placement seat 3, then activate the first electric telescopic rod 6 to drive the triangular pressing block 71 to move down, so that the triangular pressing block 71 and the two baffles 77 cooperate with the paper placement seat 3 to pre-fold the paper. After the pre-folding is completed, activate the second electric telescopic rod 73 to drive the cutting blade 74 to move down. During the downward movement of the cutting blade 74, it will push the two baffles 77 away from each other, so that the two baffles 77 rotate around the corresponding rotating shaft 75 respectively. The cutting blade 74 continues to move down until it contacts the paper and cuts the paper. After the cutting is completed, activate the second electric telescopic rod 73 to drive the cutting blade 74 to move up until it moves up to the initial position. At the same time, under the elastic action of the torsion spring 78, the rotating shaft 75 rotates in the opposite direction, and the baffles 77 return to the initial position. The two baffles 77 contact each other and block the cutting blade 74.
