Description

Technical Field

[0001] This utility model relates to the field of polyurethane plastic pipe processing technology, and in particular to a polyurethane plastic pipe burr trimming device. Background Technology

[0002] Polyurethane (PU), short for polyurethane, is a high-molecular-weight material with excellent mechanical properties formed by polyols and polyisocyanates through a condensation reaction. It is extremely ductile and has a wide range of applications, including products such as coatings, adhesives, fabric finishing agents, leather finishing agents, polyurethane flexible / rigid foams, and elastomers. It is used in textiles, construction, aviation, shipbuilding, transportation, medicine, electronics and other fields.

[0003] After polyurethane is made into plastic pipes, the rough edges of the pipes after processing are removed. However, during the trimming process, the pipes need to be clamped. Conventional clamping can easily cause vibration after the blade falls, affecting the cutting efficiency and sometimes damaging the pipes. To address these issues, we have proposed a polyurethane plastic pipe rough edge trimming device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polyurethane plastic pipe burr trimming device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A polyurethane plastic pipe burr trimming device includes a conveyor box. A bidirectional cylinder is fixed to one side of the upper end of the conveyor box. A clamping block is fixed to the end of the piston rod of the bidirectional cylinder, and two clamping blocks are arranged correspondingly. One clamping block has a snap-fit ​​groove on one side, and a first cylinder is fixed to one side of the other clamping block. The end of the piston rod of the first cylinder passes through the clamping block and extends to one end of the clamping block. A connecting plate is fixed to the end of the piston rod of the first cylinder. Two arc-shaped clamping plates are fixed to one side of the connecting plate. A support frame is provided on one side of the conveyor box. A movable sleeve is slidably connected to the upper end of the support frame. A support platform is fixed to the upper end of the movable sleeve. An installation frame is provided on the upper end of the support platform. A protective box is installed on the installation frame. A second cylinder is installed on the upper end of the protective box. A cutting tool is fixed to the end of the piston rod of the second cylinder. Multiple blade insertion slots are provided at equal intervals on the upper end of the support platform, and the blade insertion slots correspond to the cutting tools.

[0007] Preferably, a third cylinder is fixed to one side of the upper end of the support frame, the piston rod end of the third cylinder is fixed to one side of the movable sleeve, sliders are fixed to both sides of the lower end of the movable sleeve, guide rails are fixed to both sides of the upper end of the support frame, and a slider on the same side is installed on a guide rail on the same side.

[0008] Preferably, the clamping block is provided with an arc-shaped slot.

[0009] Preferably, a rubber layer is provided on one side of the arc-shaped clamping plate.

[0010] Preferably, the conveying box is provided with a conveying mechanism, and a discharge port is provided on one side of the conveying box, with the discharge port corresponding to the clamping block.

[0011] Preferably, an observation window is provided on one side of the conveyor box.

[0012] In this utility model, when it is necessary to remove the burrs from polyurethane pipes, the pipes are transported to the lower end of the protective box via the conveying mechanism of the conveying box. The bidirectional cylinder drives two clamping blocks to move towards the middle simultaneously to clamp the middle of the pipe. The first cylinder, through the extension of the piston rod, drives two arc-shaped clamping plates to clamp the pipe firmly again in the middle. The third cylinder drives the moving sleeve and the upper structure to the corresponding position. The second cylinder, through the extension of the piston rod, drives the cutter to descend and insert it into the blade slot to cut and trim the excess burrs from the pipe.

[0013] The polyurethane pipe burr trimming device of this utility model can not only adjust the blade according to the position of the pipe to fully adapt to the trimming needs of pipes of different lengths, but also further improve the stability and firmness of the polyurethane pipe clamping through two clamping, ensuring smooth burr trimming, guaranteeing processing quality, and improving processing efficiency.
