Description

Technical Field

[0001] The utility model relates to the field of cutting devices, in particular to a cutting device for anti-cracking coiled materials. Background Art

[0002] Anti-crack sticker is a roll-up waterproof membrane. Anti-crack sticker is mainly used for the construction and maintenance of highway, general highway and urban road pavement base. It has high tensile strength, good toughness and surface viscosity, suitable for pavement base, and can prevent cracks caused by temperature and vertical load from reflecting to the surface layer. When using anti-crack sticker, the wider anti-crack sticker roll needs to be cut.

[0003] According to the published patent 202021435299.0, a crack-resistant sticker coil slitting device belongs to the technical field of coil slitting devices. The crack-resistant sticker coil slitting device includes a transfer mechanism, a coil retracting mechanism and a coil cutting mechanism. The transfer mechanism includes a base plate, a push handle and a moving wheel, wherein the push handle is fixedly mounted on one side of the upper surface of the base plate, and the moving wheel is mounted on the bottom of the base plate. The coiled material retracting mechanism includes a coiled material discharging assembly and a coiled material winding assembly, wherein the coiled material discharging assembly and the coiled material winding assembly are both mounted above the base plate. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. The distance between multiple sets of sliders and cutting blades can be adjusted and fixed by adjusting bolts, and the distance between the cutting blades is set to the required cutting width. The telescopic member pushes the cutting blade downward to solve the problem that the cutting blade cannot cut the anti-crack coiled material in sections. During use, the cutting blade head of the traditional anti-crack coiled material cutting device cannot be automatically polished during use, and it is not sharp after long-term use, which easily leads to the phenomenon that the anti-crack coiled material cannot be cut smoothly. Moreover, the grinding plate is easily worn for a long time and cannot contact the cutting blade head, and the service life of the grinding plate is relatively short. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet actual needs, and provide an anti-crack coil material cutting device to solve the technical problems that the cutting head of the current anti-crack coil material cutting device cannot be automatically polished during use and the service life of the polishing plate is relatively short.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a crack-resistant coil material cutting device, including a cutting table, the interior of the cutting table is connected to a cutter protection mechanism through a groove, a cutter slot is opened inside the cutter protection mechanism, both sides of the cutter slot are opened with built-in slots, the interior of the built-in slot is connected with a buffer plate through a spring member, one end of the buffer plate is fixedly connected to a grinding plate, one side of the cutter protection mechanism is fixedly connected to a connecting rod, a first through slot is opened on one side of the cutting table, a scale beam is installed above the cutting table, the interior of the scale beam is connected to a cross-shaped moving block through a cross-shaped groove, a second through slot and a third through slot are respectively opened on both sides of the cross-shaped slot, a locking bolt is installed inside the second through slot, and the bottom of the cross-shaped moving block is connected to the cutting head through a hydraulic rod.

[0006] Preferably, one end of the spring member is fixedly connected to the inner wall of the built-in groove, and the other end of the spring member is fixedly connected to one side of the buffer plate. The size of the buffer plate matches the size of the built-in groove and is slidably connected to the inner wall thereof. 1 / 2 of the buffer plate is located inside the built-in groove.

[0007] Preferably, two grinding plates are provided, and one end of the two grinding plates is connected in a V-shape.

[0008] Preferably, one end of the connecting rod is slidably connected to the inside of the first through slot, and the other end of the connecting rod passes through the inside of the third through slot and is fixedly connected to one end of the cross-shaped moving block.

[0009] Preferably, the cross-shaped groove is located in the middle of the scale beam and is connected to the top and bottom thereof; the size of the cross-shaped moving block matches the size of the cross-shaped groove and is slidably connected to the inner wall thereof; one end of the hydraulic rod is fixedly connected to one end of the cross-shaped moving block and is slidably connected to the bottom of the scale beam; one end of the cutting head is fixedly connected to the output end of the hydraulic rod, and the other end of the cutting head corresponds to the position of the cutting slot.

[0010] Preferably, one end of the locking bolt abuts against the outer surface of the scale beam, and the other end of the locking bolt passes through the interior of the second through slot and is connected to the interior of the cross-shaped moving block through a thread.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model combines the cutter protection mechanism, the cutter slot, the built-in slot, the spring part, the buffer plate and the grinding plate. When the anti-crack sticker coil is cut, the hydraulic rod drives the cutting head to move downward, thereby cutting the anti-crack sticker coil on the cutting table. During this process, the cutting head is inserted into the inside of the cutter slot. During this process, the grinding plate grinds the cutting part of the cutting head, thereby avoiding the phenomenon that the cutting head cannot be cut smoothly due to long-term use of the cutting head.

[0013] During this process, the spring element will generate elastic force on the buffer plate, so that the buffer plate drives the grinding plate to always fit with the cutting end of the cutting head, thereby preventing the grinding plate from being unable to contact the cutting head due to long-term wear, thereby extending the service life of the grinding plate;

[0014] When selecting and adjusting the number and spacing of cutting heads, the operator first loosens the locking bolt, and then allows the locking bolt to drive the cross-shaped moving block to slide in the cross-shaped groove. The cross-shaped moving block will drive the cutting head on the hydraulic rod to move, thereby adjusting the position of the cutting head. During this process, the cross-shaped moving block will drive the cutter guard mechanism to slide inside the groove through the connecting rod, and then tighten the locking bolt so that the cutter guard mechanism moves synchronously with the cutting head, thereby avoiding the operator's subsequent positioning of the cutter guard mechanism and the cutting head.
