Description

Technical Field

[0001] The utility model belongs to the technical field of pipes, and in particular relates to automatic marking equipment for plastic pipes. Background Art

[0002] As an important component of chemical building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection, low consumption and other advantages. It is mainly made of synthetic resin, namely polyester as raw material, with stabilizers, lubricants, plasticizers, etc. added, and is extruded in a pipe making machine through the "plastic" method. There are many types of plastic pipes, including UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) water supply pipes, polypropylene PPR hot water pipes, etc.

[0003] The production process of plastic pipes mainly includes raw material processing, extrusion, shaping, cooling, marking, cutting and packaging.

[0004] Marking is an important part of the process. The main purpose of marking is to mark the necessary information on the pipe so that it can be accurately identified and understood during the subsequent installation, use and maintenance. The marking content usually includes the manufacturer's name and trademark, pipe type, model, material, implementation standard code, production date or batch number, pipe inner diameter, thickness standard, etc. This information helps to ensure the quality and safety of the pipe.

[0005] The most common marking method for plastic pipes is laser marking. In the current plastic pipe marking process, laser marking is usually performed manually by hand, which results in poor marking quality, poor stability and high labor costs. Utility Model Content

[0006] The purpose of the utility model is to provide an automatic marking device for plastic pipes in response to the above-mentioned technical problems, so as to keep the pipes in a suitable position and prevent them from deviating or leaving under the laser head, so as to realize the automation of marking and ensure the quality of marking.

[0007] In view of this, the utility model provides an automatic marking device for plastic pipes, including a frame, on which are arranged:

[0010] A positioning assembly is used to limit the position of the pipe.

[0011] In this technical solution, the tube is continuously transported on the transmission component, and then the laser marking component marks the moving tube. The positioning component is used to limit the position of the tube so that the tube is in a suitable position to prevent it from deviating or leaving under the laser head. This can realize automated marking and ensure the quality of marking.

[0012] Furthermore, the positioning component includes:

[0013] A vertical limiting wheel, wherein the vertical limiting wheel is arranged above the transmission assembly, the axis of the vertical limiting wheel is perpendicular to the transmission direction of the transmission assembly, and the outer peripheral surface of the vertical limiting wheel is used to limit the vertical position of the pipe to press the pipe onto the transmission assembly;

[0014] The lateral limiting wheels are parallely and symmetrically arranged on both sides of the vertical limiting wheels, the axis of the lateral limiting wheels is lower than the vertical limiting wheels, and the sides of the two lateral limiting wheels are used to limit the lateral position of the pipe.

[0015] In this technical solution, the vertical limiting wheel is pressed on top of the pipe, pressing the pipe onto the transmission assembly without jumping up and down, and the lateral limiting wheels are arranged on both sides of the pipe. The sides of the two lateral limiting wheels work together to keep the lateral position of the lateral limiting wheels unchanged, but the pressure of the vertical limiting wheel and the lateral limiting wheel are relatively small, which will not hinder the forward transmission of the pipe along the transmission assembly.

[0016] Furthermore, rubber pads are provided on the outer peripheral surface of the vertical limiting wheel and the side surfaces of the lateral limiting wheels.

[0020] Furthermore, the vertical adjustment structure includes:

[0021] A fixing plate, wherein the fixing plate is fixedly connected to the frame;

[0022] A connecting frame, wherein the connecting frame is slidably arranged on the fixed plate and is fixedly connected to the vertical limiting wheel;

[0023] The regulating cylinder is fixedly arranged on the fixing plate, and the piston rod output end of the regulating cylinder is fixedly connected to the connecting frame.

[0024] In the technical solution, the adjusting cylinder is started to move the piston rod with the connecting frame, so that the vertical limiting wheel can move vertically.

[0025] Furthermore, the lateral adjustment structure includes:

[0026] A connecting shaft, the connecting shaft passes through the axis of the vertical limiting wheel and is fixedly connected to the vertical limiting wheel, the two lateral limiting wheels are slidably sleeved on the connecting shaft and are located on both sides of the vertical limiting wheel, and the axis of the two lateral limiting wheels is lower than the connecting shaft;

[0027] Side plates, the connecting frame includes a horizontal plate and two side plates perpendicular to the horizontal plate, the horizontal plate is fixedly connected to the vertical limiting wheel, the two side plates are respectively arranged in parallel on the outside of the two lateral limiting wheels, and the outside of the side plates are fixedly provided with an adjusting motor;

[0028] An adjusting screw, wherein the adjusting screw is parallel to the connecting shaft, the adjusting screw crosses the side plate, the lateral limit wheel and the vertical limit wheel, one end of the adjusting screw is fixedly connected to the output end of the adjusting motor, the adjusting screw includes threaded sections with opposite spiral directions at both ends, the two threaded sections are respectively spirally connected to the two lateral limit wheels, and the adjusting screw is rotationally connected to the side plate and the vertical limit wheel.

[0029] In the technical solution, the adjusting motor is started to make the adjusting screw rotate circumferentially, so that the two lateral limiting wheels spirally connected to the adjusting screw are moved closer to or farther away from each other.

[0030] Furthermore, two positioning components are provided along the transmission direction of the transmission component, and are respectively provided on both sides of the laser marking component.

[0031] Furthermore, a dust collection component is provided on the transmission path of the transmission component, and the dust collection component is located in front of the laser marking component and is used to clean dust and debris at the location to be marked.

The positioning component is used to limit the position of the tube, so that the tube is in a suitable position to prevent it from deviating or leaving under the laser head.
