Technical Field

[0001] The utility model belongs to the technical field of printing devices, and in particular relates to a cutting machine for printing production. Background Art

[0002] The cutting machine is used for dividing and cutting sheets in various industries. It does not require any molds. It is controlled by system software and then cuts the products directly. As long as the corresponding parameters are set on the operating platform, the computer transmits the corresponding instructions to the cutting machine. The cutting machine will quickly cut according to the received design drawings, with a high degree of automation and simple operation.

[0003] Of course, cutting machines are also used in printing production, but there will be the following problems when cutting printed products with softer materials (such as thinner cardboard). Due to the friction between the cutter and the printed product, that is, after the cutter is cut, when it is pulled out, the cutter will drive the cut end of the printed product to move upward under the action of friction, which will cause bending or flashing near the cut section of the printed product, resulting in poor cutting effect. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a cutting machine for printing production, so as to solve the problem that when the cutting machine in the prior art cuts printed products with softer materials, the cutter will drive the cut end of the printed product to move upward, resulting in bending and flashing.

[0007] Furthermore, the telescopic element is a hydraulic rod or an electric push rod.

[0008] Furthermore, the side surfaces of the symmetrically arranged auxiliary pressing blocks facing the cutter are all inclined surfaces that are narrow at the top and wide at the bottom.

[0009] Furthermore, a telescopic rod is sleeved on the outer side of the spring, and the telescopic rod includes an inner rod and an outer rod which are slidably sleeved, and one end of the inner rod and the outer rod are respectively fixed to the mounting plate and the auxiliary pressing block.

[0010] Furthermore, the cutting platform is provided with a groove, the groove corresponds to the position where the cutting knife acts on the cutting platform, and the groove is filled with a rubber pad.

[0011] Furthermore, a plurality of supporting legs are provided below the cutting platform, and the plurality of supporting legs are arranged at the four corners of the cutting platform.

[0012] Furthermore, a universal wheel is provided on one end of the support leg that contacts the ground.

[0013] The beneficial effects of the utility model are:

[0014] In the utility model, the symmetrically arranged auxiliary pressing blocks can squeeze and compact the two ends of the cut product by the cutter, so that when the cutter is cutting and when the cutter is pulled out of the cutting position (the cutter is pulled out first, and the auxiliary pressing blocks are separated later), the friction between the cutter and the cut product is not enough to drive the cut end to move, that is, the cut end of the cut product will not be bent or have flash, so the cutting effect can be improved;

[0015] (2) This technical solution cleverly utilizes the telescopic function of the output end of the telescopic element to achieve the pressing and disengagement of the auxiliary pressure block without the need for other driving elements, which simplifies the overall complexity of the device to a certain extent and achieves the purpose of energy saving and environmental protection.

[0023] like Figures 1 to 3 As shown, the utility model is a cutting machine for printing production, comprising a cutting platform 1, on which a gantry 3 is provided, and the gantry 3 is arranged in the width direction of the cutting platform 1. It is not difficult to understand that an input conveyor belt mechanism and an output conveyor belt mechanism can be provided on the cutting platform 1 to transport the printed cardboard 9 or other products to the cutter 5, and output the cut products to a specified position. A plurality of evenly distributed telescopic elements 4 are provided on the gantry 3. The number of the telescopic elements 4 in this specific embodiment is 3, and they are arranged perpendicular to the cutting platform 1. The fixed end of the telescopic element 4 is fixed on the gantry 3, and the output end of the telescopic element 4 faces the cutting plate 9. A platform 1 is set, and a cutter 5 is provided between the telescopic element 4 and the cutting platform 1. One end of the cutter 5 is fixed on the output end of the telescopic element 4, and auxiliary pressure blocks 7 are symmetrically provided on both sides of the cutter 5 in the width direction. A plurality of springs 8 are provided on the side surface of the auxiliary pressure block 7 facing the gantry 3. One end of the spring 8 is fixed on the auxiliary pressure block 7, and the other end of the spring 8 is fixed on a mounting plate 6 set on the output end of the telescopic elements 4. Under normal circumstances, the distance between the auxiliary pressure block 7 and the cutting platform 1 is smaller than the distance between the cutter 5 and the cutting platform 1. The mounting plate 6 refers to a plate arranged parallel to the cutting platform 1, and three places on the plate are respectively connected to the output end of the telescopic element 4.

[0024] The working principle of the above technical solution is as follows:

[0025] When the telescopic element 4 extends and drives the cutter 5 to move toward the cardboard 9 for cutting, since the mounting plate 6 is connected to the output end of the telescopic element 4, it will drive the auxiliary pressing block 7 to move toward the cardboard 9, and since the auxiliary pressing block 7 is closer to the cardboard 9, the auxiliary pressing block 7 will first contact the cardboard 9. After the contact, the telescopic element 4 that continues to move downward will cause the mounting plate 6 to compress the spring 8, so that the auxiliary pressing block 7 can press the cardboard 9 on both sides of the cutting position, and then when the cutter 5 is cutting and when the cutter 5 is pulled out of the cutting position (the cutter 5 is pulled out first, and the auxiliary pressing block 7 is detached later), the friction between the cutter 5 and the cardboard 9 is not enough to drive the cutting end of the cardboard 9 to move, thereby improving the cutting effect of the cardboard 9.

[0026] In one practicable manner, the telescopic element 4 is a hydraulic rod or an electric push rod.

[0027] In one feasible manner, the side of the symmetrically arranged auxiliary pressing block 7 facing the cutter 5 is an inclined surface that is narrow at the top and wide at the bottom. This inclined surface arrangement will result in a wide upper space to avoid dryness between the upper part and the telescopic element 4 or the cutter 5. At the same time, the narrow lower space is to enable the auxiliary pressing block 7 to be closer to the cutting part of the cardboard 9, which can further enhance the squeezing effect on the end of the cardboard 9 at the cutting part.

[0028] In one feasible manner, a telescopic rod is sleeved on the outer side of the spring 8, and the telescopic rod includes an inner rod and an outer rod that are slidably sleeved. One end of the inner rod and the outer rod are respectively fixed to the mounting plate 6 and the auxiliary pressure block 7. The setting of the telescopic rod limits the lateral displacement of the auxiliary pressure block 7 so that it can only move vertically, thereby avoiding the problem of the auxiliary pressure block 7 being tilted due to force during the compression process of the spring 8.

[0029] In one feasible manner, a groove is provided on the cutting platform 1, and the groove corresponds to the position where the cutter 5 acts on the cutting platform 1. The groove is filled with a rubber pad 10. The setting of the rubber pad 10 can prevent the blade of the cutter 5 from rigidly contacting the cutting platform 1, thereby protecting the cutter 5.

[0030] In one feasible manner, a plurality of support legs 2 are provided under the cutting platform 1, and the plurality of support legs 2 are arranged at the four corners of the cutting platform 1. Universal wheels are provided on the ends of the support legs 2 that contact the ground. The arrangement of the universal wheels facilitates the transportation and movement of the device.

[0031] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
