Description

Technical Field

[0001] The utility model relates to the technical field of tire production, and more specifically to a cutting device of a calender for tire production. Background Art

[0002] Tires are circular elastic rubber products that are grounded and rolled on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impact, achieve contact with the road surface and ensure the driving performance of the vehicle. The work process includes mixing process, rubber component preparation process, extrusion, calendering, bead forming and other processes. Calendering process is an important process in tire production. The raw material cord passes through the calender and a thin layer of rubber is hung on both sides of the cord. The final product is called "cord". After the cord is pressed, it needs to be cut.

[0003] However, during the process of cutting the cord fabric, most of the existing calenders may fail to press the cord fabric tightly before cutting, which may cause the cord fabric to shift and be damaged during cutting. Also, before cutting the cord fabric, most calenders may cause the cord fabric to be uneven, which may cause wrinkles during the production process of the cord fabric and affect the cutting, thereby reducing the quality of the product. Therefore, this scheme proposes a cutting device for a calender for tire production. Utility Model Content

A bottom plate 6 is fixedly connected to the front end of the conveying box 1, a motor 61 is installed at the upper end of the bottom plate 6, and a transmission assembly 7 is movably installed between the motor 61 and the rotating shaft of the conveying roller 2 3, a tooling table 8 is fixedly connected to the side end of the conveying box 1, and a clamping assembly 9, a cutting assembly 10 and a clamping assembly 2 11 are installed on the upper end of the tooling table 8 from left to right.

[0029] During use of the present solution, in order to avoid the phenomenon in the prior art that the unevenness of the curtain cloth causes wrinkles and the deviation occurs when cutting in an unflattened state, which causes the product to be damaged, in the present embodiment, the curtain cloth to be cut is first inserted into the feed port 4, and then passes between several groups of conveying rollers 1 2 and 2 3, and the curtain cloth is passed out of the discharge port 5, and then driven by the motor 61, the transmission assembly 7 is driven to transmit, thereby driving the rotating shaft of each group of upper conveying rollers 2 3 to transmit, so that the curtain cloth placed between the upper and lower parts at this time is transported to the surface of the right workbench 8 until it passes through the pressing assembly 9. , cutting component 10, pressing component 2 11, after the curtain moves to the appropriate cutting distance, the personnel can drive the pressing component 1 9 and the pressing component 2 11 to press the front and rear sides of the lower curtain, and finally drive the cutting component 10 to complete the cutting of the lower curtain. Compared with the prior art, the utility model can make the plane of the curtain to be cut flat under the multi-roller conveying mode, so that wrinkles are not easy to appear. At the same time, when cutting, the front and rear sides of the cutting position of the curtain are pressed by two groups of pressing components, which is beneficial to the cutting device on the middle side to cut, thereby improving the product quality of the curtain when cutting.

[0030] See also Figure 1-2 The transmission assembly 7 includes two connecting rods 71, and the two connecting rods 71 ​​are respectively fixedly connected to the rotating shafts passing through the conveying roller 3, wherein the outer ends of the connecting rods 71 ​​are installed with multiple wheel discs 72, and the front end of the conveying box 1 is rotatably connected with a connecting rod 2 73, one end of the connecting rod 2 73 is fixedly connected to the output end of the motor 61, and the outer end of the connecting rod 2 73 is installed with a wheel disc 2 75, and a belt 74 is installed between the wheel discs 72 on the two connecting rods 71 ​​and between one group of wheel discs 72 and the connecting rod 2 73.

[0031] During use of this scheme, each group of conveying rollers 2 3 is provided with two rollers arranged up and down, and the rotating shaft of each upper roller passes through the outside of the conveying box 1 so as to be connected with two connecting rods 1 71 outside, wherein the outer surface of the right connecting rod 1 71 is connected with a wheel disc 1 72, and the surface of the left connecting rod 1 71 is connected with two wheel discs 1 72, and a belt 74 is sleeved between the wheel discs 1 72 on the same horizontal plane as the right side, and the two wheel discs 1 72 are used as driven wheels, and another belt 74 is sleeved between another wheel disc 1 72 on the surface of the left connecting rod 1 71 and the wheel disc 2 75 on the lower right side. 4, and because the connecting rod 2 73 is fixedly connected to the output end of the motor 61, it is used as a driving wheel.
