Description

Technical Field

[0001] This utility model relates to the field of rolling technology, specifically to a rolling molding device for plastic products. Background Technology

[0002] When processing plastic products, they often need to be rolled into specific shapes on their surface by pressure rollers to achieve aesthetic or functional effects. However, the distance between the upper and lower pressure rollers of existing plastic product roll forming equipment is generally fixed and non-adjustable, making it unsuitable for roll forming different plastic products.

[0003] A search revealed that patent application CN219947271U discloses a plastic product rolling molding device, including a grooved seat, movable blocks, a vertical screw, a hollow inner roller, a molding plate, a support plate, a horizontal screw, and a locking block. The grooved seat has symmetrical movable grooves on both sides that mate with the movable blocks. The upper and lower ends of the movable grooves have symmetrical vertical threaded holes that mate with the vertical screw. There are two sets of movable blocks, and each set of movable blocks rotatably supports the hollow inner roller. The horizontal screw can lock the plug-in block, thereby facilitating the installation and removal of the molding plate.

[0004] However, due to the design of the grooved seat, the distance between the two sets of outer molding rollers cannot be freely adjusted according to the needs. It can only process plastics of a specific thickness, which is not very practical. At the same time, when the plug-in block is locked by the locking block, the plug-in block is easily shaken, which affects the stability of the two sets of molding plates and results in poor rolling effect.

[0005] Therefore, we propose a rolling molding device for plastic products. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a plastic product rolling molding device, which solves the problems of low practicality and poor rolling effect of existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a plastic product roll forming device, including a base plate, four sets of support rods with opposite positions are fixedly installed on the top surface of the base plate, and a top plate is fixedly installed on the top of the support rods;

[0029] The working principle and usage process of this utility model are as follows: When the device is required to work, the telescopic cylinder 6 drives the fixed frame B7 to move downward according to the requirements. The distance between the fixed frame A4 and the fixed frame B7 is the distance between the upper pressure roller 8 and the lower pressure roller 5. This allows for rolling of plastics of different thicknesses, improving practicality. The connecting shaft 13 is placed on the rotating shaft 10, with the slot 11 and slot B14 corresponding. Then, the screws are installed in the mounting holes A12 and B15. The threaded installation ensures the stability of the connection, preventing shaking and offset between the connecting shaft 13 and the rotating shaft 10, thereby improving the stability and effectiveness of the lower pressure roller 5 and the upper pressure roller 8.
