Description

Technical Field

[0001] The utility model relates to the technical field of plastic-lined pipe processing equipment, and particularly relates to a cutting device for plastic-lined pipe processing. Background Technique

[0002] The plastic-lined pipe, namely the steel-plastic composite pipe, is based on ordinary carbon steel pipe and lined with thermoplastic plastic with excellent chemical properties. It is formed by cold drawing composite or rotational molding. It has both the mechanical properties of steel pipe and the corrosion resistance of plastic pipe, the characteristics of slow scale formation and not easy to grow microorganisms, and is an ideal pipe for transporting media such as acids, alkalis, salts, and corrosive gases. During the processing of plastic-lined pipes, cutting equipment is needed to cut the plastic pipes used for plastic-lined pipe processing into the designed length for the subsequent efficient processing of plastic-lined pipes.

[0003] The Chinese patent with the publication number of CN221089211U discloses a cutting device for plastic-lined pipe processing, belonging to the technical field of plastic-lined pipe processing equipment, including: a support mechanism, the support mechanism includes a support plate, a moving plate is arranged on the surface of the support plate, two double-threaded lead screws are rotatably connected to the surface of the moving plate, two connecting blocks are threadedly connected to the surfaces of both double-threaded lead screws, and a first clamping block is fixedly connected to the surface of one connecting block.

[0004] Although the cutting device for plastic-lined pipe processing described in the above patent can clamp and cut plastic pipes of different sizes during use, and can also conveniently collect the debris generated during the cutting process to avoid affecting the subsequent cutting, the cutting device for plastic-lined pipe processing with the above structure needs to first loosen the clamping mechanism after each cutting, and then realize the feeding of the pipe to be cut by manual lifting and moving. Since the feeding process of the pipe after each cutting is relatively cumbersome, the standby time of the equipment is relatively long during the whole cutting process of plastic pipes, resulting in relatively low cutting efficiency of plastic pipes.

[0006] The technical problem to be solved by the utility model is to provide a cutting device for plastic-lined pipe processing that can realize the automatic feeding of plastic pipes in a clamped state after each cutting in view of the current situation of the prior art.

[0007] (2) Technical Solutions

[0008] The utility model is implemented through the following technical scheme: the utility model proposes a cutting device for processing plastic-lined pipes, including a cutting table, a bracket is installed in the middle of the upper end of the cutting table, a cutting mechanism is installed on the bracket, and two clamping and guiding mechanisms are symmetrically installed on the cutting table on both sides of the cutting mechanism, the clamping and guiding mechanisms include a V-shaped support installed on one side of the upper end of the cutting table, two rows of supporting rollers symmetrically installed on both sides of the upper end of the V-shaped support, two electric slide rails symmetrically installed on the cutting table on both sides of the V-shaped support, an electric telescopic rod installed on the sliding block provided on the electric slide rail, a mounting plate installed on the telescopic part of the electric telescopic rod, guide wheels installed at equal intervals at the bottom end of the mounting plate, and a drive motor installed on the upper end of the mounting plate facing each of the guide wheels.

[0009] Furthermore, the cutting mechanism includes an electric cylinder installed on the top of the bracket, a cutting motor installed on the telescopic part of the electric cylinder, and a cutting wheel installed on the power output end of the cutting motor.

[0010] By adopting the above technical solution, when the plastic pipe fittings for plastic-lined pipe processing to be cut are moved directly below the cutting wheel, the electric cylinder drives the high-speed rotating cutting wheel to move downward, thereby achieving the cutting of the plastic pipe fittings.

[0011] Furthermore, an operation panel is installed on one side wall of the bracket, and the operation panel is electrically connected to the electric cylinder, the cutting motor, the electric slide rail, the electric telescopic rod and the driving motor.

[0013] Furthermore, a material drop hole is provided on the cutting table directly below the cutting wheel, and a material receiving box is slidably installed on the cutting table below the material drop hole.

[0014] By adopting the above technical solution, the debris generated during the cutting process will fall into the material receiving box through the material dropping hole and be collected.

[0015] Furthermore, the V-shaped support is bolted to the cutting table, and the support roller is rotatably connected to the V-shaped support.

[0018] By adopting the above technical solution, the electric slide rail is mainly used to adjust the height of the guiding wheel to ensure that the height of the guiding wheel is aligned with the central part of plastic pipe fittings of different pipe diameters.

[0019] Further, the driving motor is bolted to the mounting plate, and the driving motor corresponds to the guiding wheel one by one.

[0020] By adopting the above technical solution, the driving motor drives the clamped guiding wheel to rotate, so that the feeding of plastic pipe fittings can be realized in the clamped state.

[0021] Further, the guiding wheel is a rubber wheel, the outer wall of the guiding wheel is an inwardly concave arc structure, and the wheel shaft of the guiding wheel is connected to the driving motor through a coupling.

[0022] By adopting the above technical solution, it can be ensured that the guiding wheel rotates conveniently under the action of the driving motor.

[0023] (III) Beneficial effects

[0024] The present utility model has the following beneficial effects compared with the prior art:

[0025] To solve the problem that the existing cutting equipment for plastic-lined pipe processing can clamp and cut plastic pipes of different sizes during use, and can also conveniently collect the debris generated during the cutting process to avoid affecting subsequent cutting. However, the cutting equipment for plastic-lined pipe processing with the above structure needs to loosen the clamping mechanism first after each cut, and then manually lift and move the pipe fitting to be cut to realize the feeding of the pipe fitting. Since the feeding process of the pipe fitting is relatively cumbersome after each cut, the standby time of the equipment is relatively long during the entire cutting process of the plastic pipe fitting, resulting in relatively low cutting efficiency of the plastic pipe fitting. The present utility model installs two guiding mechanisms symmetrically on both sides of the cutting mechanism, so that when the device cuts the plastic pipe fitting for plastic-lined pipe processing, the plastic pipe fitting can be clamped and fixed under the action of the support, the support roller, the electric slide rail, the electric telescopic rod and the guiding wheel. At the same time, with the cooperation of the driving motor driving the guiding wheel to rotate, the automatic sliding feeding of the plastic pipe fitting can be realized after one cut, avoiding the cumbersome operation of manual lifting and moving for feeding, reducing the standby time of the equipment during the feeding of the plastic pipe fitting, making the entire cutting process of the plastic pipe fitting for plastic-lined pipe more continuous and having higher cutting efficiency.

Then, clamp the guiding wheel 306 on both sides of the plastic pipe fitting with the help of the electric telescopic rod 305.
