Description

Technical Field

[0001] The present application relates to the technical field of paper cutters, and in particular to a paper feeding structure for a paper cutter. Background Art

[0002] "CN217777131U" discloses "a paper feeding mechanism for a paper cutter, comprising a carrier plate, a groove is provided on the upper surface of the carrier plate... a slide seat is symmetrically installed at the bottom of the base, and the slide seat is slidably connected to the slide rail." The utility model uses a double-acting cylinder external control device to control the extension and retraction of the active end of the double-acting cylinder by the control device, and the active end of the double-acting cylinder is extended to make two symmetrically arranged metal plates move relative to each other, so that the metal plates abut against the stacked paper, and the paper is flattened left and right. At the same time, the push plate is manually pushed to move, so that the push plate abuts against the front end of the paper, so that the push plate can flatten the paper front and back, which is simple to operate and improves the efficiency of paper sorting and alignment.

[0003] With regard to the above-mentioned related technologies, the inventor believes that the positioning and leveling of paper by driving two metal plates to move relative to each other through multiple double-acting cylinders makes the manufacturing cost of the entire mechanism relatively high, and multiple double-acting cylinders require an external control device and preset parameters to achieve synchronization, and the operation is relatively cumbersome and complicated. In addition, after the paper is aligned, it is necessary to manually push the push plate repeatedly to drive the paper feeding, which increases the labor of the workers. Therefore, a paper feeding structure for a paper cutter is proposed to solve the above problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that the relative movement of two metal plates driven by multiple double-acting cylinders to position and level the paper results in a high manufacturing cost of the entire mechanism, the present application provides a paper feeding structure for a paper cutter.

[0006] The paper feeding structure for a paper cutter provided in the present application adopts the following technical solution:

[0007] The camming mechanism is a kind of mechanism that the camming mechanism is made up of the one-piece structure and the one-piece structure of the camming mechanism.

[0008] Preferably, positioning plates are fixedly connected to inner walls on both sides of one end of the conveying device, and the positioning plates are located above the surface of the conveying device.

[0009] Preferably, a plurality of telescopic columns are fixedly connected to the outer walls opposite to the two clamps, one end of the plurality of telescopic columns away from the clamps is fixedly connected to a connecting plate, and the outer walls of the plurality of telescopic columns are all sleeved with springs.

[0010] Preferably, a plurality of fixed shafts are fixedly connected to the top inner wall of the connecting plate, and rubber rollers are rotatably connected to the outer walls of the plurality of fixed shafts.

[0011] Preferably, the plurality of fixed axes are arranged uniformly in an equidistant linear array along the length direction of the connecting plate.

[0012] Preferably, two side outer walls of the conveying device are fixedly connected with a plurality of fixing feet, and the plurality of fixing feet are evenly distributed at both ends of the conveying device.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] Through the set leveling mechanism, the two clamping plates can be driven to move relative to each other, thereby driving multiple rubber rollers to abut against the stacked papers, leveling the papers left and right, and then the stacked papers are driven to move and abut against the positioning plate through the conveying device to achieve front and back leveling. Compared with the prior art, the leveling mechanism in the utility model only uses a single cylinder to drive the two clamping plates to move relative to each other, which is not only simple to operate but also reduces the manufacturing cost. In addition, after the leveling is completed, the stacked papers can be directly fed into the paper cutter through the conveying device, without the need for manual feeding, thereby reducing labor intensity.

The bottom outer wall of the width-direction slider 5 is fixedly connected to a movable plate 6, and the ends of the two connecting rods 16 away from the driving rod 15 are respectively hinged on the bottom middle outer walls of the two movable plates 6. The bottom outer wall of the movable plate 6 is fixedly connected to two U-shaped connecting frames 7, and the ends of the two U-shaped connecting frames 7 away from the movable plate 6 are fixedly connected to the clamping plate 8. The leveling mechanism also includes a cylinder 18 fixedly installed on the top outer wall of one of the movable plates 6, and a fixed block 17 is fixedly connected to the bottom outer wall of the mounting plate 3 near the connecting shaft 14, and the output end of the cylinder 18 is fixedly connected to the fixed block 17.

[0022] Positioning plates 19 are fixedly connected to the inner walls on both sides of one end of the conveying device 1 , and the positioning plates 19 are located above the surface of the conveying device 1 .

[0023] A plurality of telescopic columns 9 are fixedly connected to the opposite outer walls of the two clamps 8 , and a connecting plate 11 is fixedly connected to one end of the telescopic columns 9 away from the clamps 8 . Springs 10 are sleeved on the outer walls of the telescopic columns 9 .

[0024] A plurality of fixed shafts 12 are fixedly connected to the inner wall of the top of the connecting plate 11 , and a rubber roller 13 is rotatably connected to the outer walls of the plurality of fixed shafts 12 .

[0025] The plurality of fixed shafts 12 are evenly arranged in a linear array with equal spacing along the length direction of the connecting plate 11 .

[0026] A plurality of fixing feet 2 are fixedly connected to the outer walls of both sides of the conveying device 1 , and the plurality of fixing feet 2 are evenly distributed at both ends of the conveying device 1 .

[0027] The implementation principle of the paper feeding structure for a paper cutter in the embodiment of the present application is as follows: when in use, the conveying device 1 can be fixed in a suitable position by means of a plurality of fixing feet 2 using fastening bolts, and then the stacked paper is placed on the conveying device 1, and the stacked paper is aligned and leveled by means of a leveling mechanism;

[0028] Start the cylinder 18, the output end of the cylinder 18 contracts, driving a movable plate 6 to move close to the fixed block 17, at this time the movable plate 6 drives the slider 5 to slide on the outer wall of the guide rail 4, playing a limiting role, so that the movable plate 6 can move stably linearly, when one movable plate 6 moves, it will push a connecting rod 16 inward, so that the connecting rod 16 rotates, at this time one connecting rod 16 will push one end of the driving rod 15, the driving rod 15 will rotate around the connecting shaft 14, thereby causing the other end of the driving rod 15 to rotate and displace, and then will pull the other connecting rod 16 to move inward, the other connecting rod 16 will drive the other movable plate 6 to move synchronously, at this time the two movable plates 6 will move relatively synchronously, when the two movable plates 6 move relative to each other, the U-shaped connecting frame 7 pushes the two clamping plates 8 to move relative to each other, thereby driving a plurality of rubber rollers 13 to abut against the stacked paper, and level the paper left and right;

[0029] When the multiple rubber rollers 13 come into contact with the stacked paper, they can convert direct friction into rolling friction, reduce friction, and facilitate the stacked paper to be flattened left and right. They can also be driven to move by the conveying device 1, and because the material of the rubber rollers 13 has elasticity, they can play a buffering role. Then, through the mutual cooperation of the telescopic column 9 and the spring 10, the elastic force generated by the multiple springs 10 can further buffer the clamping force generated by the cylinder 18, so as to avoid excessive clamping force causing wrinkles on the edges of the stacked paper;

[0030] When the stacked papers are leveled left and right, the conveying device 1 is started to drive the stacked papers close to the positioning plate 19, and the multiple rubber rollers 13 rotate in coordination. When the stacked papers are against the positioning plate 19, as the conveying device 1 continues to operate, the stacked papers are fitted with the surface of the positioning plate 19 to achieve front and back leveling. After the overall leveling of the papers is completed, the conveying device 1 drives the stacked papers to move away from the positioning plate 19, and the papers are fed into the paper cutter to complete the paper feeding process.
