Abstract
Description
Technical Field
[0001] This utility model relates to the field of PVC pipe marking technology, and in particular to a PVC pipe production marking device. Background Technology
[0002] Marking is a crucial step in the production and processing of PVC pipes, requiring the marking of specifications, materials, production dates, and other information onto the pipe surface. Existing marking devices often suffer from accuracy issues due to pipe fixation and posture adjustments. PVC pipes are prone to bending and deformation due to storage environment and their own weight. If placed directly on a load-bearing structure, the pipe surface cannot maintain a straight line, leading to marking position deviation. Traditional marking devices (such as those patented with announcement numbers CN222387843U and CN222875596U) often use segmented fixing methods. While this limits movement in parts of the pipe, the pipe between fixing points may still deviate from a straight line due to bending. Furthermore, segmented fixing can easily cause localized compression deformation of the pipe, affecting product quality. In addition, dust, debris, and other impurities remaining from storage may adhere to the PVC pipe surface. If not cleaned beforehand, this can result in blurred marking patterns and insufficient adhesion, further reducing the marking effect. Utility Model Content
[0003] The purpose of this utility model is to provide a marking device for PVC pipe production, which solves the problems of inaccurate marking position due to the possible bending of PVC pipe during the existing PVC pipe marking process, the easy deformation and damage of PVC pipe caused by the traditional segmented fixing method, and the impact of impurities on the surface of PVC pipe on the marking quality.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A marking device for PVC pipe production, comprising:
[0006] The connecting frame is U-shaped and has a V-shaped groove extending along its length at the top;
[0007] A fixing component, located at one end of the connecting frame, includes a pressure rod that can extend into the PVC pipe for pressing the PVC pipe wall onto the V-groove.
[0008] The drive assembly is located between the two arms of the connecting frame, and the slider connected to it can move along the length of the V-groove.
[0009] The lifting assembly is located on the slider, and the bottom is equipped with a marking machine and a cleaning assembly.
[0010] Preferably, the fixing component further includes a cylinder, the cylinder output end is connected to the fixing block, the pressure rod is fixed to the fixing block and has a rubber pad at the bottom, and the connecting frame is provided with a vertical groove for the fixing block to move.
[0011] Preferably, the drive assembly includes a motor, a screw, and a guide rod. The motor is fixedly mounted on the outer wall of one arm of the connecting frame. The two ends of the screw are rotatably connected between the two arms of the connecting frame through bearings, and one end of the screw is coaxially fixedly connected to the output shaft of the motor. The guide rod is arranged parallel to the screw, and its two ends are fixedly connected to the two arms of the connecting frame. The screw thread passes through the slider, and the guide rod slides through the slider.
[0012] Preferably, the lifting assembly includes a connecting rod, two vertical rods, and an electric push rod. The electric push rod is fixedly installed on the top of the slider, and its output shaft is fixedly connected to the top of the connecting rod. The two vertical rods are fixedly installed on the top of the connecting rod and slide through the slider. The marking machine is fixedly installed on one side of the bottom of the connecting rod, and the cleaning assembly is fixedly installed on the other side of the bottom of the connecting rod.
[0013] Preferably, the cleaning assembly includes a connecting shell, a telescopic sleeve, a spring, and a cleaning block. The connecting shell is horizontally positioned below the connecting rod. The top end of the telescopic sleeve is fixedly connected to the bottom of the connecting rod, and the bottom end is fixedly connected to the top of the connecting shell. The spring is sleeved on the outside of the telescopic sleeve, with its top end abutting against the bottom of the connecting rod and its bottom end abutting against the top of the connecting shell. The cleaning block is fixed to the bottom of the connecting shell, and the bottom of the cleaning block can contact the surface of the PVC pipe.
[0014] Preferably, it also includes a vacuuming assembly, which includes a vacuum cleaner and a hose. The vacuum cleaner is fixedly installed on the top of the slider. One end of the hose is connected to the vacuum port of the vacuum cleaner, and the other end is connected to the inside of the connecting shell. The bottom of the connecting shell has a vacuum port that corresponds to the cleaning block.
[0015] This utility model has at least the following beneficial effects:
[0016] The PVC pipe is fixed at one point by a fixing component, avoiding excessive constraints on the pipe caused by traditional segmented fixing and preventing deformation and damage to the pipe due to fixing. During the marking process, the slider drives the cleaning component and the marking machine to move from the fixed end to the other end of the pipe. The connecting shell first contacts the surface of the PVC pipe and squeezes the pipe through the elasticity of the spring. As it moves, it gradually fits the curved pipe into the inner wall of the V-shaped groove, keeping the entire marking path straight and effectively solving the problem of marking position deviation on curved pipes.
[0017] When the cleaning block of the cleaning component moves in contact with the PVC pipe, it can remove impurities adhering to the surface; at the same time, the vacuum cleaner is connected to the connecting shell through a hose, which can immediately suck up the debris generated during cleaning, so as to avoid the impurities remaining and affecting the clarity and adhesion of the marking pattern, and reduce subsequent cleaning processes.
[0018] The fixing component achieves rapid fixing by driving the pressure rod with a cylinder. The driving component and the lifting component realize the horizontal movement of the slider and the lifting of the marking machine through screw drive and electric push rod, respectively. The components work together precisely and have a high degree of automation. There is no need for manual adjustment of the pipe posture, which reduces the difficulty of operation and improves the marking efficiency. Attached Figure Description

[0037] The pressure rod 54 is horizontally fixed to the side wall of the fixing block 51 facing the V-groove 11, and a rubber pad 53 is fixed to the bottom of the pressure rod 54. The rubber pad 53 can move down with the pressure rod 54 and press the PVC pipe wall tightly against the inner wall of the V-groove 11.
[0038] Furthermore, driver component 2 includes:
[0039] Motor 21 is fixedly installed on the outer wall of one arm of the connecting frame 1;
[0040] The screw 22 has its two ends rotatably connected between the two arms of the connecting frame 1 via bearings, and one end of the screw 22 is coaxially and fixedly connected to the output shaft of the motor 21.
[0041] The guide rod 23 is set parallel to the screw 22, and its two ends are fixedly connected to the two arms of the connecting frame 1 respectively;
[0042] The slider 3 has a first through hole and a threaded hole. The guide rod 23 slides through the first through hole, and the screw 22 is threaded through the threaded hole. The motor 21 can drive the screw 22 to rotate and drive the slider 3 to slide back and forth along the guide rod 23.
[0043] Furthermore, the lifting assembly 6 includes:
[0044] The connecting rod 61 is horizontally positioned below the slider 3;
[0045] Two vertical rods 62 are parallel and vertically fixed to the top of the connecting rod 61. The slider 3 has a second through hole corresponding to the position of the two vertical rods 62. The two vertical rods 62 slide through the corresponding second through hole respectively.
[0046] An electric push rod 63 is fixedly installed on the top of the slider 3, and its output shaft extends vertically downward and is fixedly connected to the top center of the connecting rod 61.
[0047] The marking machine 7 is fixedly installed on one side of the bottom of the connecting rod 61, and the cleaning component 4 is fixedly installed on the other side of the bottom of the connecting rod 61.
[0048] Furthermore, cleanup component 4 includes:

[0053] Furthermore, it also includes a vacuuming component, which includes:
[0054] Vacuum cleaner 41 is fixedly installed on the top of slider 3;
[0055] The hose 42 has one end connected to the suction port of the vacuum cleaner 41 and the other end connected to the inside of the connecting shell 43. The bottom of the connecting shell 43 has a suction port corresponding to the cleaning block 45.
[0056] In summary, the PVC pipe to be marked is placed in the V-groove 11 of the connecting frame 1, so that one end of the PVC pipe is close to the fixing component 5 and fitted onto the surface of the pressure rod. The cylinder 52 of the fixing component 5 is activated, and the output shaft of the cylinder 52 drives the fixing block 51 to move down along the vertical groove, which in turn drives the pressure rod 54 to descend. The rubber pad 53 at the bottom of the pressure rod 54 presses the wall of the PVC pipe tightly against the inner wall of the V-groove 11, thus completing the fixing of one end of the PVC pipe.
[0057] Start the electric push rod 63 of the lifting assembly 6. The output end of the electric push rod 63 extends, pushing the connecting rod 61 to descend vertically along the slider 3 via the vertical rod 62 until the cleaning block 45 of the cleaning assembly 4 contacts the surface of the PVC pipe. At this time, the spring 44 is slightly compressed, the telescopic sleeve retracts, and the marking machine 7 descends to the marking preparation position close to the surface of the PVC pipe. Start the vacuum cleaner 41 to put it into standby mode.
[0058] The motor 21 of the drive assembly 2 is started, and the motor 21 drives the screw 22 to rotate. Under the threaded transmission of the screw 22 and the guidance of the guide rod 23, the slider 3 moves smoothly from the fixed end of the PVC pipe to the other end along the length of the V-groove 11.
[0059] During the movement, the cleaning block 45 of the cleaning component 4 first contacts the surface of the PVC pipe and remains in contact with the pipe surface under the elastic force of the spring 44, wiping and cleaning impurities such as dust and debris on the surface of the PVC pipe; at the same time, the vacuum cleaner 41 sucks away the impurities generated during cleaning through the suction port of the hose 42 and the connecting shell 43.
[0060] As slider 3 continues to move, if the PVC pipe is bent, connecting shell 43 will gradually press the bent part towards V-groove 11 through squeezing action, so that the PVC pipe gradually fits the inner wall of V-groove 11 and maintains a straight state; then the marking machine 7 moves with slider 3 to the position to be marked and performs marking operation on the surface of PVC pipe.
[0061] After the marking operation is completed, the motor 21 reverses, driving the slider 3 to move in the opposite direction along the guide rod 23 to the initial position; the electric push rod 63 retracts, driving the connecting rod 61, the marking machine 7 and the cleaning component 4 to rise and reset; the cylinder 52 drives the fixing block 51 to rise, the pressure rod 54 disengages from the inside of the PVC pipe, and the marked PVC pipe is removed, thus ending the entire marking process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
