Description

Technical Field

[0001] The utility model relates to the technical field of clamping and fixing devices for processing plastic products, in particular to a clamping and fixing device for processing plastic products. Background Art

[0002] Plastic processing is also called plastic molding processing. It is a general term for various processes that convert synthetic resins or plastics into plastic products. It is a large production sector in the plastics industry. Plastic processing generally includes plastic batching, molding, machining, joining, modification and assembly. The last four processes are carried out after the plastic has been molded into finished products or semi-finished products, also known as plastic secondary processing. In the process of plastic processing, clamping devices are often required to assist in its processing, and clamping devices are mainly devices to prevent the workpiece from displacement during the processing process.

[0003] For example, patent No. CN202321190124.1 discloses a clamping device for processing plastic products, whose structure includes a load-bearing plate, a slide groove is provided on the upper surface of the load-bearing plate, an adjusting rod is movably installed on the load-bearing plate through the slide groove, a fixing rod and a mounting rod are fixedly installed on the upper surface of the load-bearing plate, a compression spring is fixedly installed between the outer surface positions of the adjusting rod and the fixing rod, an adjusting plate is movably installed between the outer surface positions of the fixing rod and the adjusting rod, and a mounting groove is provided between the upper and lower surface positions of the adjusting plate. The clamping force can be effectively limited according to the different sizes and models of different plastic products, so that it can always remain stable during use, which greatly avoids the possibility of damage to the plastic products caused by changes during use. At the same time, it can also simplify the operation steps of returning it to its original position after use, making its overall operation and maintenance more convenient. The utility model is composed of a horizontal base, a fixed clamping plate, a movable clamping plate, an anti-slip slider, an anti-slip groove, a mounting seat, a fastening screw, a servo motor, a rotating shaft, a support plate, a rack plate, and a gear. The mounting seat, the fastening screw, the servo motor, the rotating shaft, the support plate, the rack plate, and the gear constitute a clamping mechanism. The clamping mechanism can drive the two movable clamping plates to move closer to or away from each other. The movable clamping plate and the fixed clamping plate can automatically correct the clamping point according to the shape of the plastic product, and the clamping effect is better. At the same time, the two groups of movable clamping plates and the fixed clamping plates constitute a double clamping channel to improve the clamping efficiency;

[0004] The clamping device in this patent is only suitable for clamping and fixing one type of plastic product, and the clamping and fixing device is only in one way, which has certain limitations and is relatively common. It cannot clamp according to different plastic products. At the same time, multiple clamping methods cannot be interchanged well and are not flexible enough. Utility Model Content
