Description

Technical Field

[0001] The utility model relates to the technical field of full - open paper cutters, in particular to an auxiliary paper feeding device for a full - open paper cutter. Background Technique

[0002] A full - open paper cutter is an industrial device used for cutting paper and other materials. It can cut large sheets of paper, usually the full - open size, that is, the size of the original paper without any cutting, into the required sizes. This kind of machine is widely used in industries such as printing, packaging, advertising, and publishing, for cutting products such as books, magazines, posters, and packaging boxes. To improve the paper cutting efficiency, multiple sheets of paper are usually stacked into a paper stack for batch paper cutting. Therefore, an auxiliary device is needed during paper cutting processing to improve the paper cutting accuracy.

[0003] For example, an auxiliary paper feeding device for a full - open paper cutter disclosed in the Chinese Patent Publication No. (CN213259739U) includes a baffle, a first positioning plate, and a second positioning plate connected to the operation table. The baffle is located on one side of the gantry, and the first positioning plate and the second positioning plate are located on the other side of the gantry. A guide plate is arranged between the first positioning plate and the second positioning plate. The guide plate is slidably connected to the operation table along the direction of approaching or departing from the baffle. A driving mechanism for driving the sliding of the guide plate is arranged on the operation table. This application has the effect of improving the neatness during paper stack cutting, thereby improving the product quality.

[0004] However, in the prior art exemplified by the above - mentioned disclosed patent, there is still a problem of poor paper feeding adjustment effect for paper stack cutting. In the prior art, to facilitate paper stack cutting processing, the paper stack is pushed under the paper cutter blade by driving the guide plate to move for paper cutting. However, the height of the guide plate in this method is limited. During paper cutting, the thickness of the paper stack needs to be controlled below the height of the guide plate, otherwise the excess part cannot be normally pushed in. Different - hardness papers can be stacked to different heights, and some easily cut papers will be stacked thicker to improve the cutting efficiency. The existing method is not convenient for adjusting according to the thickness of the paper stack, which affects the paper cutting efficiency. Content of the Utility Model

[0008] Furthermore, a controller is provided on the outside of the machine table. The right side of the splicing push plate and the right side of the paper feeding push plate are located on the same horizontal plane.

[0009] Furthermore, a moving opening is formed in the upper surface of the machine table, and the moving plate is slidably connected between the inner walls on the front and rear sides of the moving opening.

[0010] Furthermore, an adjustment opening is formed in the left side of the paper feeding push plate, and the two sliders are slidably connected between the inner walls on the upper and lower sides of the adjustment opening. The height of the slider is equal to the distance between the inner walls on the upper and lower sides of the adjustment opening.

[0011] Furthermore, a limiting plate is fixed to the middle of the left side of the paper feeding push plate and located outside the bidirectional screw, and a rotating hole for the bidirectional screw to be rotatably connected is formed in the outside of the limiting plate.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 , an auxiliary paper feeding device for a full-open paper cutter in this embodiment includes a machine table 1 and a paper cutter main body 2 disposed in the middle of the upper surface of the machine table 1. A paper feeding mechanism 3 for facilitating the adjustment of auxiliary paper feeding into the paper cutter main body 2 is provided on the lower surface of the machine table 1, and a distance control mechanism 4 for controlling the paper cutting size is provided on the right side of the upper surface of the machine table 1.

[0025] Please refer to Figures 2 to 4 , in order to facilitate the adjustment of auxiliary paper feeding into the paper cutter main body 2, the paper feeding mechanism 3 in this embodiment includes a cylinder 31 fixed to the lower surface of the machine table 1. A moving plate 32 is fixed to the outside of the output shaft of the cylinder 31, and a paper feeding push plate 33 is fixed to the upper surface of the moving plate 32. By starting the cylinder 31, the output shaft of the cylinder 31 retracts, driving the moving plate 32 to move, and then pushing the paper feeding push plate 33 to move towards the paper cutter main body 2. Fixing plates 34 are fixed to the front and rear ends of the left side of the paper feeding push plate 33. A bidirectional screw 35 is rotatably connected between the opposite sides of the two fixing plates 34 through bearings. The bidirectional screw 35 is a threaded screw rod with opposite thread directions at the left and right ends. A driving motor 36 is fixed to the back of the rear fixing plate 34. The outside of the output shaft of the driving motor 36 is fixed to the outside of the bidirectional screw 35. Two sliders 37 are threadedly connected to the outside of the bidirectional screw 35. Clamping plates 38 are fixed to the right sides of the two sliders 37. A socket 39 is fixed to the upper surface of the paper feeding push plate 33. A splicing push plate 310 is inserted outside the socket 39 of the socket 39. Place the paper to be cut on the machine table 1 and stack it into a paper pile. When the height of the paper pile exceeds the height of the paper feeding push plate 33, take out a splicing push plate 310 with a suitable height and insert it outside the socket 39 of the paper feeding push plate 33, and ensure that the splicing push plate 310 and the paper feeding push plate 33 are on the same horizontal plane for auxiliary paper feeding.

[0026] In this embodiment, a controller is provided on the outer side of the machine table 1. The right sides of the splicing push plate 310 and the paper feeding push plate 33 are located on the same horizontal plane. A moving opening is formed on the upper surface of the machine table 1, and the moving plate 32 is slidably connected between the front and rear inner walls of the moving opening. During the movement, the paper cutting size is determined in cooperation with the distance control mechanism 4. When one side of the paper stack abuts against the distance control mechanism 4, the movement stops, and the paper cutting machine main body 2 is started to perform the cutting process of the paper. An adjustment opening 311 is formed on the left side of the paper feeding push plate 33, and the two sliders 37 are both slidably connected between the upper and lower inner walls of the adjustment opening 311. The height of the slider 37 is equal to the distance between the upper and lower inner walls of the adjustment opening 311. In the middle of the left side of the paper feeding push plate 33 and outside the bidirectional screw 35, a limiting plate is fixed, and a rotating hole for the bidirectional screw 35 to be rotatably connected is formed on the outer side of the limiting plate. After the paper cutting is completed, the driving motor 36 is started. The output shaft of the driving motor 36 drives the bidirectional screw 35 to move. The movement of the bidirectional screw 35 drives the two sliders 37 and the clamping plate 38 to move in opposite directions. The clamping plate 38 clamps the paper stack. As the air cylinder 31 drives the paper feeding push plate 33 to move outwards, the paper stack is taken out for edge-changing operation or adjusting the position of the paper stack to facilitate the next cutting.

[0027] Please refer to Figure 5 , in order to control the paper cutting size, the distance control mechanism 4 in this embodiment includes a support base 41 fixed on the upper right side of the machine table 1. Sliding openings are formed on both the left and right sides of the support base 41, and an adjustment strip 42 is slidably connected to the inner walls of the two sliding openings. A distance control plate 43 is fixed to the left side of the adjustment strip 42. A sliding hole is formed on the upper surface of the support base 41, and a plug pin 44 is slidably connected to the inner wall of the sliding hole. A connecting plate 45 is fixed to the bottom end of the plug pin 44. According to the size of the paper to be cut, the cutting position is determined using the scale on the front of the machine table 1. By sliding the adjustment strip 42 in the sliding opening of the support base 41, the position of the distance control plate 43 is adjusted to set the cutting size. And a toothed 46 is fixed to the lower surface of the connecting plate 45. A number of tooth grooves 47 for the toothed 46 to be inserted are formed on the upper surface of the adjustment strip 42. The plug pin 44 is inserted into the support base 41 and the toothed 46 is inserted into the appropriate tooth groove 47 on the adjustment strip 42 to fix the position of the adjustment strip 42 and ensure the accuracy of the cutting size.

[0028] In this embodiment, a number of tooth grooves 47 are respectively arranged in an array along the length direction of the adjustment strip 42. A scale is fixed on the front of the machine table 1. Before cutting, ensure that the paper is aligned with the distance control plate 43 to ensure the straightness of the cutting and the consistency of the size. Start the cutting action of the paper cutting machine main body 2 and perform the cutting along the position set by the distance control plate 43. After the cutting is completed, take out the cut paper and prepare for the cutting of the next batch of paper.

[0029] The working principle of the above embodiment is as follows:

[0030] (1) Place the paper to be cut on the machine table 1 and stack it into a paper pile. When the height of the paper pile exceeds the height of the paper feed push plate 33, take out the splicing push plate 310 with a suitable height, insert it outside the socket 39 of the paper feed push plate 33, and ensure that the splicing push plate 310 and the paper feed push plate 33 are on the same horizontal plane to assist in paper feeding. By starting the cylinder 31, the output shaft of the cylinder 31 retracts, driving the moving plate 32 to move, and then pushing the paper feed push plate 33 to move towards the paper cutting machine main body 2. During the movement, cooperate with the distance control mechanism 4 to determine the cutting size. When one side of the paper pile fits against the distance control mechanism 4, stop moving. Start the paper cutting machine main body 2 to perform the cutting process of the paper. After the paper cutting is completed, start the driving motor 36. The output shaft of the driving motor 36 drives the bidirectional screw 35 to move. The movement of the bidirectional screw 35 drives the two sliders 37 and the clamping plate 38 to move in opposite directions. The clamping plate 38 clamps the paper pile. As the cylinder 31 drives the paper feed push plate 33 to move outwards, the paper pile is taken out for edge-changing operation or adjusting the position of the paper pile to facilitate the next cutting.

[0031] (2) According to the size of the paper to be cut, use the scale on the front of the machine table 1 to determine the cutting position. Move the sliding adjustment strip 42 within the sliding opening of the support seat 41 to adjust the position of the distance control plate 43 to set the cutting size. Insert the pin 44 into the support seat 41 and use the engaging teeth 46 to insert into the appropriate tooth grooves 47 on the adjustment strip 42 to fix the position of the adjustment strip 42 and ensure the accuracy of the cutting size. Before cutting, ensure that the paper is aligned with the distance control plate 43 to ensure the straightness of the cutting and the consistency of the size. Start the cutting action of the paper cutting machine main body 2 and perform the cutting along the position set by the distance control plate 43. After the cutting is completed, take out the cut paper and prepare for the cutting of the next batch of paper.
