Description

Technical Field

[0001] The utility model relates to the technical field of trimming devices, and more specifically, to a novel trimming and slitting device for PVC products. Background Art

[0002] In the production process of PVC coated fabrics and knife-coated fabrics, trimming and slitting is an important and indispensable link. The trimming and slitting devices widely used in the current market mainly include a utility knife holder device and a circular knife holder device. However, these two devices have obvious deficiencies in practical applications.

[0003] The utility knife holder device mainly uses iron or stainless steel metal materials to make a metal inner shell similar to a utility knife as the knife holder, and is fixed to the connecting rod of the production line through a hoop device. Although the device has a simple structure, it requires one worker on each side to operate simultaneously during operation, resulting in low efficiency, and it is impossible to change the knife seamlessly. The use efficiency of the blade is not high, and burrs are easily generated. The circular knife holder device uses a combination of an iron metal disc and a mold to fix multiple blades. Although the circular knife holder device can realize the rotation and replacement of the blades, there are safety hazards in rotating the blades in the production environment, the use efficiency of the blades is still low, and it also requires workers on both sides to operate. These deficiencies limit the production efficiency, increase the cost, and may have an adverse impact on the product quality. At present, no effective solutions have been proposed for the problems in the related technologies. Summary of the Utility Model

[0004] In view of the problems in the related technologies, the present utility model proposes a novel trimming and slitting device for PVC products to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To this end, the specific technical solution adopted by the present utility model is as follows:

[0006] A novel trimming and slitting device for PVC products includes a connecting rod. On both sides of the surface of the connecting rod, adjusting cylinders are slidably installed. On one side of the adjusting cylinder, a support rod is fixedly connected. At the end of the support rod, a main knife holder is fixedly connected. On both sides of the surface of the main knife holder, adjusting grooves are opened. In the adjusting grooves, lifting holes are opened. In the lifting holes, a clamping screw one is slidably installed. On the surface of the clamping screw, a secondary knife holder is threadedly connected. The secondary knife holder is slidably installed in the adjusting groove. On the surface of the secondary knife holder, a blade groove is opened. On one side of the blade groove, a clamping block is fitted and installed. On the surface of the clamping block, a clamping screw two is rotatably installed. The clamping screw two is threadedly connected with the secondary knife holder. A cutting blade is clamped and installed in the blade groove. On one side of the connecting rod, a knife holder adjusting mechanism is provided.

[0007] Further, in order to simultaneously adjust the main tool holder on the connecting rod, the tool holder adjusting mechanism includes a threaded hole formed on one side of the connecting rod. An elevating screw rod is threadedly connected inside the threaded hole. Both ends of the elevating screw rod are rotatably connected to a support frame. A limiting groove is formed on one side of the surface of the support frame. One side of the connecting rod is fixedly connected to a limiting rod, and the limiting rod is slidably installed in the limiting groove.

[0008] Further, in order to fix the adjusting cylinder after installation, a clamping screw rod III is threadedly connected to the surface of the adjusting cylinder, and a positioning block is fixedly connected to the end of the clamping screw rod III.

[0009] Further, in order to increase the friction between the sub-tool holder and the adjusting groove, anti-slip lines are provided on one side of the surface of the sub-tool holder.

[0010] Further, in order to facilitate the screwing adjustment of the elevating screw rod, a screwing ring is fixedly connected to the top of the elevating screw rod.

[0011] Further, in order to facilitate the fixed installation of the support frame on both sides of the production line, mounting plates are fixedly connected to both ends of the support frame, and positioning holes are formed on the surface of the mounting plates.

[0012] Further, in order to facilitate the lifting of the sub-tool holder during adjustment, a lifting ring is fixedly connected to the top of the sub-tool holder.

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

[0014] 1. Through the tool holder adjusting mechanism on the connecting rod, after screwing the elevating screw rod, the connecting rod drives the main tool holder on its surface to move simultaneously, realizing the simultaneous control of multiple tool holders, greatly reducing the number of operators, and significantly improving work efficiency; and after both sub-tool holders installed in the adjusting groove are installed with cutting blades, the innovative double-knife mode enables seamless tool change for the blades, avoiding efficiency losses caused by production interruption during tool change, and at the same time eliminating accidental cutting accidents that may occur during tool change in traditional devices, greatly improving operation safety.

[0015] 2. The adjustable installation method of the cutting blade on the sub-tool holder, compared with traditional art knife holders and disc knife holders, enables full utilization of each blade part of the art knife, reduces production costs, and the optimized cutting method enables the device to adapt to the non-destructive cutting requirements of multi-segment cut products, improving the processing precision and quality of the products.
