Description

Technical Field

[0001] The utility model relates to the technical field of material processing, in particular to a material cutting device for polymer material production. Background Art

[0002] The cutting device for polymer material production is a device specially used for cutting polymer materials, including but not limited to various plastics, rubbers and fibers. This device usually adopts precision cutting mechanisms, such as circular blades, scissors or laser cutting technology, to ensure the accuracy and uniformity of material cutting. In the production process of polymer materials, precise cutting is very important to ensure the quality of products. Whether in the manufacture of polymer sheets, films or fibers, the design and operation of the cutting device can adapt to the physical properties of different materials, such as viscosity, elasticity and hardness, thereby ensuring high efficiency and low scrap rate of the cutting process.

[0003] After searching, the document of announcement number "CN215241253U" mentioned that "the utility model discloses a cutting device for polymer material production, which belongs to the technical field of equipment for polymer material production, including a base, a lifting angle column is fixedly installed at the bottom of the base, and a conical leakage groove is opened inside the base, a pumping pipe is fixedly sleeved at the bottom end of the base, and a pumping pump is fixedly installed on one side of the bottom of the base, a feed pipe is fixedly installed on one side of the pumping pump, and a placement plate is fixedly installed on the top of the base". When in use, by setting an angle adjustment mechanism, a motor and a cutting blade, the height of the motor can be adjusted by using a positioning block during the use of the cutting device for polymer material production. The cutting device for polymer material production can be adjusted, and the angle of the motor can be adjusted using a movable sleeve, so that the cutting blade is in close contact with the workpiece, thereby avoiding the problem that the cutting device for polymer material production is not convenient for adjusting the angle, thereby improving the cutting efficiency of the cutting device for polymer material production. However, in the shearing process of polymer materials, especially the cutting operation of thinner materials such as rubber, when cutting, the feeding length and feeding method are relatively traditional, and mistakes are easy to occur in the specific feeding length, which can easily cause excessive feeding. In the cutting process, when cutting, due to the lack of constraints on the rubber sheet, it is easy to cause position deviation due to the cutting of the shear knife, resulting in poor cutting effect.

[0004] Therefore, we provide a cutting device for polymer material production to solve the above problems. Utility Model Content

[0017] 2. Through the setting of the polymer material feeding mechanism, when the rubber sheet is being transported, when the rubber sheet passes over the friction rubber wheel, due to the different thickness of the rubber sheet, in order to allow the friction rubber wheel to contact the rubber sheet as much as possible, so as to make the length and distance measurement more accurate, the force damping can automatically press down when subjected to the extrusion force, so as to ensure that the rotation will not be affected, and can also be automatically calibrated without affecting the normal transportation process.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-4 As shown, the utility model provides a technical solution: a cutting device for polymer material production, comprising a cutting frame 1 and a polymer material feeding mechanism 2, wherein the polymer material feeding mechanism 2 is installed on the front side of the cutting frame 1;

[0026] The polymer material feeding mechanism 2 comprises a feeding component 21 and a distance sensing component 22 . The feeding component 21 is installed on the front side of the cutting frame 1 , and the distance sensing component 22 is arranged in the middle of the feeding component 21 .

[0027] Furthermore, the feeding assembly 21 includes a supporting wall 211, a motor frame 212, a feeding motor 213, a rubber wheel 214 and a telescopic motor 215. The front side of the cutting frame 1 is installed with a supporting wall 211, the upper side of the supporting wall 211 is installed with a motor frame 212, the middle of the motor frame 212 is provided with a feeding motor 213, the end of the feeding motor 213 is provided with a rubber wheel 214, and the front side of the motor frame 212 is provided with a telescopic motor 215. When needed, the feeding motor 213 in the motor frame 212 drives the rotation of the rubber wheel 214, thereby transporting the rubber sheet sandwiched between the upper and lower rubber wheels 214. In this way, the transportation of the rubber sheet can be more stable through friction, reducing the occurrence of unexpected situations such as slipping, and ensuring the stability of the transportation length.

[0028] Furthermore, the telescopic motor 215 and the motor frame 212 are welded, and the motor frame 212 and the supporting wall 211 form a telescopic structure through the telescopic motor 215. When transporting, the motor frame 212 can be driven downward by the telescopic motor 215 first, and as the motor frame 212 moves downward, the distance between the upper and lower sets of rubber wheels 214 will become closer, thereby achieving the effect of adjusting according to the thickness of the rubber sheet, thereby improving transportation stability.

[0029] Furthermore, the distance sensing component 22 includes a feeding table 221, a force-bearing bottom plate 222, a force-bearing damper 223, an axle frame 224, a friction rubber wheel 225, a signal generator 226 and a signal receiver 227. The feeding table 221 is installed in the middle of the supporting wall 211, the force-bearing bottom plate 222 is welded to the upper middle side of the feeding table 221, the force-bearing bottom plate 222 is provided with a force damper 223 on the upper side, the axle frame 224 is welded to the upper side of the force damper 223, the friction rubber wheel 225 is installed in the middle of the axle frame 224, and the friction rubber A signal generator 226 is provided on the right side of the wheel 225, and a signal receiver 227 is provided on the right side of the signal generator 226. When the rubber sheet is being transported, when the rubber sheet passes over the friction rubber wheel 225, due to the different thicknesses of the rubber sheets, in order to allow the friction rubber wheel 225 to contact the rubber sheet as much as possible, thereby making the length distance measurement more accurate, the force damping 223 can automatically press downward when subjected to extrusion force, thereby ensuring that the rotation will not be affected and can also be automatically calibrated without affecting the normal transportation process.

[0030] Furthermore, the friction rubber wheel 225 is rotationally connected to the shaft frame 224. The friction rubber wheel 225 is made of rubber. When the rubber sheet is transported, the friction rubber wheel 225 can rotate with the movement of the rubber sheet through the friction force between the friction rubber wheel 225 and the rubber sheet, thereby measuring the length of the rubber sheet.

[0031] Furthermore, the signal receiver 227 is electrically connected to the signal generator 226, and the signal receiver 227 and the signal generator 226 are at the same horizontal height. As the friction rubber wheel 225 rotates, the signal generator 226 connected to the friction rubber wheel 225 will also rotate. As the signal generator 226 rotates, an electrical signal will be fed back to the signal receiver 227 according to the number of circles, thereby achieving the measurement of the distance.

[0032] Embodiment 2

[0033] See also Figure 1 and Figure 3As shown, in contrast to Example 1, as another implementation of the utility model, a cutting assembly 3 is installed on the inner side of the cutting frame 1, and the cutting assembly 3 includes a hydraulic master pump 31, an extrusion hydraulic rod 32, an extrusion constraint plate 33, a shear pump rod 34 and a shear knife 35. A hydraulic master pump 31 is welded in the middle of the cutting frame 1, and an extrusion hydraulic rod 32 is welded on the lower side of the hydraulic master pump 31, and an extrusion constraint plate 33 is welded on the lower side of the extrusion hydraulic rod 32. A shear pump rod 34 is arranged in the middle of the extrusion hydraulic rod 32, and a shear knife 35 is arranged at the end of the shear pump rod 34. When it is needed, as the extrusion hydraulic rod 32 moves downward, the extrusion hydraulic rod 32 will generate a thrust on the extrusion constraint plate 33, thereby constraining the rubber sheet and making the shearing process more stable.

[0034] Furthermore, the shear knife 35 and the shear pump rod 34 are connected by screws, and the shear knife 35 and the extrusion constraint plate 33 are of the same length. After being fixed, the shear pump rod 34 pushes the shear knife 35 to shear the rubber sheet, so that after the rubber sheet is sheared, it will not affect the pressing of the extrusion constraint plate 33, making the incision smoother.

[0035] Working principle: A cutting device for polymer material production is moved to a working position. When in use, the first step is to place the cutting frame 1 at the position where it needs to be used, and then the rubber sheet is inserted into the middle of the rubber wheel 214 on the inner side of the support wall 211. After insertion, the motor frame 212 is driven downward by the telescopic motor 215 to squeeze the rubber wheel 214, so that the rubber sheet is clamped, and then the feeding motor 213 starts to rotate to feed the material. The second step is that during the feeding process, the rubber sheet and the friction rubber wheel 225 generate friction and extrusion, and the extrusion will be along with the force-bearing bottom plate 222. The force damping 223 on it is used for shock absorption and buffering, and as the friction rubber wheel 225 in the shaft frame 224 rotates, the friction rubber wheel 225 will drive the signal generator 226 to rotate, and at the same time, the electrical signal will transmit the number of circles information to the signal receiver 227 when rotating. In the third step, after reaching the specified length, the hydraulic master pump 31 first controls the extrusion hydraulic rod 32 to drive the extrusion constraint plate 33 downward to extrude and fix the rubber sheet, and as the shear pump rod 34 drives the shear knife 35 downward, shearing is performed, thereby completing the use process of a cutting device for polymer material production.
