TECHNICAL FIELD

[0001] The utility model relates to the field of die cutting knife belt, especially to a die cutting knife belt grinding device. BACKGROUND

[0002] When directly grinding the tooth shape of the die cutting knife belt, it is difficult to accurately control the size of each tooth. Due to the wear of the grinding wheel, the vibration of the equipment and the slight error of the feeding system and other factors in the grinding process, the height and thickness of the tooth may deviate. For example, during the grinding process, the grinding wheel will wear after grinding a certain number of teeth, and its diameter will become smaller. If it is not compensated in time, the height of the subsequent ground teeth will be slightly lower than that of the previous teeth. Such size deviation may cause uneven stress on the die cutting knife belt during cutting, affecting cutting accuracy and the service life of the die cutting knife belt. In the prior art, in order to cope with the wear and consumption of the grinding wheel, the grinding wheel needs to be disassembled regularly, and after the grinding wheel is repaired, it is put into use again, which is time-consuming and laborious.

[0027] In an embodiment, the middle part of the grinding wheel repairing device 120 has a rotating shaft, the end of the rotating shaft is provided with a grinding wheel repairing device support frame 122, the support stability of the grinding wheel repairing device 120 can be ensured by the grinding wheel repairing device support frame 122, the contact area with the grinding wheel 110 is increased, the quality of the repairing is ensured, and the position of the grinding wheel repairing device 120 is prevented from moving when the grinding wheel 110 is close to and abuts against the grinding wheel repairing device 120.

[0028] In an embodiment, the base 200 is fixedly arranged on a support frame 300; the support frame 300 is sequentially provided with a first cleaning device 310 and a second cleaning device 320 along the running direction of the die cutter belt 101; as Figure 1As shown, in the first half, the die cutter belt 101 moves from left to right, the first cleaning device 310 is mainly used to remove the more obvious dust or sundries on the surface of the die cutter belt 101, so the first cleaning device 310 can use a brush or a blowing device for preliminary cleaning; the second cleaning device 320 is used to thoroughly remove sundries and stubborn sundries on the surface of the die cutter belt 101; therefore, the wiping assembly for clamping both sides of the die cutter belt 101 is preferred, and the clamping force of the wiping assembly can effectively remove stubborn debris or sundries on the surface of the die cutter belt 101, and the wiping assembly can be selected from common wiping materials such as non-woven fabric and sponge block; preliminary cleaning using the first cleaning device 310 can also reduce the accumulation of sundries on the surface of the die cutter belt 101 after being removed by the second cleaning device 320, thereby avoiding scratches on the surface of the die cutter belt 101.

[0029] In an embodiment, the support frame 300 is provided with a grinding support seat 330 for supporting the grinding of the die cutter belt 101 opposite the grinding wheel 110; the grinding support seat 330 can support the die cutter belt 101 on one side, and at least one side of the grinding support seat 330 is provided with a clamping assembly 340 for clamping the die cutter belt 101, so that the die cutter belt 101 can be effectively attached to the grinding support seat 330, reducing vibration during grinding and improving grinding quality; in an embodiment, the grinding support seat 330 can be provided with a clamping assembly, but the clamping height of the clamping assembly is lower than the width of the die cutter belt 101, so that the part of the die cutter belt 101 that needs to be ground at the top is leaked out, facilitating cooperation with the grinding wheel 110 for grinding, at this time the grinding support seat 330 has better support effect, which can maximize the reduction of vibration during grinding of the die cutter belt 101;

[0030] In an embodiment, the die cutter belt grinding device is provided with two grinding wheels respectively for grinding both sides of the die cutter belt 101; for example, Figure 1As shown, the rear side die cutting knife belt grinding device also has the first cleaning device 310 and the second cleaning device 320; but at this time, the functions of the first cleaning device 310 and the second cleaning device 320 are slightly different, at this time, the two cleaning devices are mainly used to clean the debris generated by the previous grinding device grinding; these debris mainly come from the part of the die cutting knife belt 101 material ground off by the grinding wheel 110. If not cleaned in time, the debris will accumulate in the grinding area. The accumulation of debris may increase the surface roughness of the die cutting knife belt 101. Because the ground debris particles may be repeatedly ground between the die cutting knife belt 101 and the grinding wheel 110, the surface of the die cutting knife belt 101 that has been ground may be scratched, damaging its surface precision. Moreover, these debris may also embed into the tooth groove of the die cutting knife belt 101, affecting the precision of the tooth shape and the cutting performance of the die cutting knife belt 101; the grinding debris is also easy to enter the pores of the grinding wheel 110, causing the grinding wheel 110 to be blocked. Therefore, through the first cleaning device 310 and the second cleaning device 320, not only can the grinding quality be improved, but also the grinding wheel 110 can be effectively prevented from being blocked, the grinding efficiency can be ensured, and the debris can be prevented from entering the slider 130 and the linear guide 220, thereby prolonging the service life of the equipment.

[0031] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent transformation or direct or indirect application in the related technical field based on the content of the present application specification and drawings is also included in the patent protection range of the present application.
