Description

Technical Field

[0001] The utility model relates to the technical field of polyolefin pipe processing, in particular to a chipless cutting machine for polyolefin pipes. Background Art

[0002] Polyolefin pipes are a type of piping material made from polyolefin polymers. Polyolefins are a class of polymer compounds with carbon and hydrogen as the main elements. Their molecular structure is mainly composed of carbon-carbon single bonds and carbon-hydrogen bonds.

[0003] The patent specification with announcement number CN219987735U discloses a chipless cutting machine for polyolefin pipes, comprising a cutting table, an electric cylinder fixedly mounted on the upper end of the cutting table, a cutting machine mounted on the output end of the electric cylinder, a fixed plate welded to one side of the upper end of the cutting table, a servo motor fixedly mounted on the rear end of the other side of the fixed plate, and a bidirectional screw mounted on the output end of the servo motor. The technical solution of this utility model, through the provision of a cutting table, a clamping plate, a transparent cloth, and a through-hole, when in use, can not only enable the bidirectional screw to cooperate with the screw sleeve to drive the clamping plate to move toward the middle, so that the clamping plate clamps and limits the polyolefin pipe, thereby facilitating the cutting of the pipe, but also, during the rotation of the bidirectional screw, the transparent cloth on the right side of the fixed frame cooperates with the fixed plate to cover the cutting space, thereby reducing the escape of debris during the cutting process, eliminating the trouble of manual cleaning, and further reducing pollution to the working environment.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned polyolefin pipe chip-free cutting machine has the following problems: the above-mentioned equipment adopts a barrier method to prevent flying debris from flying out of the cutting table, but most of the debris is blocked by the transparent cloth and the debris will be concentrated on the cutting table. The material of the polyolefin pipe itself is a recyclable material, and the debris falling on the cutting table is not concentrated. After being blocked by the transparent cloth, it may be scattered on the cutting table due to impact, which is not conducive to the operator to recycle and reuse the debris. In view of this, a polyolefin pipe chip-free cutting machine is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a chipless cutting machine for polyolefin pipes.

[0006] The cam is provided with a toothed plate on the top of the operating table, and a toothed plate is provided on the bottom of the operating table to prevent the toothed plate from being cut off.

[0007] As a further description of the above technical solution: the bottom of the cutting assembly is in contact with the pipe body, the bottom of the frame plate is in contact with the top of the folding plate, the inner side of the groove behind the bottom of the top plate is in contact with the outer side of the magnetic block, and the outer side of the magnetic block is magnetically fixed to the rear of the bottom of the top plate. This not only keeps the working environment clean and tidy, reduces the pollution of debris to the workplace, and improves the overall hygiene of the workplace, but also the collected debris can be recycled and reused, thereby improving the utilization rate of materials and reducing waste.

[0008] As a further description of the above technical solution: the center of the guide rail is in a disconnected state, and the output end of the fan and the feed trough of the hollow box are both in a horizontal straight line with the disconnection point in the center of the guide rail. The width of the disconnection point in the center of the guide rail is one and a half times smaller than the feed trough on the rear end face of the hollow box. A top-down groove is opened in the middle below the front end face of the gantry plate, and the shape of the groove in the middle below the front end face of the gantry plate matches the shape of the feed trough and is interconnected with the feed trough. The debris generated when the cutting component cuts the pipe body can be blown by the fan to allow the debris to enter the hollow box through the feed trough, making it convenient to collect the debris.

[0009] As a further description of the above technical solution: a slide groove running from left to right is opened in the middle of the front side of the top of the hollow box, and the cross-sectional shape and size of the slide groove in the middle of the front side of the top of the hollow box match the cross-sectional shape and size of the frame plate, and the length of the frame plate matches the longitudinal length inside the hollow box. A pin for fixing the folding plate is provided at the bottom of the hollow box, which allows the frame plate to drive the nylon net to slide up and down in the hollow box. Part of the debris entering the hollow box falls on the top of the folding plate, and part is stuck to the nylon net. Both methods are convenient for operators to collect the debris.

[0010] As a further description of the above technical solution: the depth and cross-sectional shape of the groove opened in the middle of the rear bottom of the top plate match the thickness and cross-sectional shape of the magnetic block. The material of the top plate is metal that can be magnetically fixed by the magnetic block, which allows the magnetic block to magnetically fix the top plate, thereby improving the stability of the frame plate and nylon mesh in the hollow box to a certain extent.

[0011] As a further description of the above technical solution: hydraulic rods are fixedly connected to the front and rear end surfaces below the gantry plate, a push block is fixedly connected to the output end of the hydraulic rod, a damping block is fixedly connected to the inner end surface of the push block, the outer side of the push block is slidably connected to the front and rear sides of the inside of the guide rail, the inner top end of the damping block and the inner end surface of the push block are in contact with the front and rear sides of the pipe body, and the edge of the cut part of the pipe body can be squeezed and fixed when the cutting assembly cuts the pipe body, effectively preventing the rotating saw blade in the cutting assembly from driving the pipe body to rotate together.

[0012] As a further description of the above technical solution: the number of the hydraulic rods is four, and the hydraulic rods are distributed at the top positions on the left and right sides of the front and rear ends below the gantry plate. Four through grooves are opened at the front and rear ends in the middle of the guide rail, and the positions and longitudinal cross-sectional shapes of the through grooves match the positions and longitudinal cross-sectional shapes of the push blocks, so that the hydraulic rods drive the corresponding push blocks to the upper left, lower left, upper right and lower right positions of the center of the pipe body, respectively, to facilitate the cutting of the center of the pipe body by the cutting assembly.

[0013] As a further description of the above technical solution: the inner end face of the push block is provided with a slope inclined thirty degrees from the upper inner side to the lower outer side. The number of the damping blocks is several, and the damping blocks are evenly distributed at the position of the inner end slope of the push block, which can effectively increase the friction between the push block and the surface of the pipe body, and improve the stability of the cutting assembly when cutting the pipe body to a certain extent.

[0014] The utility model has the following beneficial effects:

[0015] The chip-free cutting machine for polyolefin pipes designed by the present invention can collect the debris generated by the cutting component when cutting the pipe body through the design coordination of the fan and the hollow box, and set a nylon net with an intercepting effect inside the hollow box, which not only keeps the working environment clean and tidy, reduces the pollution of the workplace by debris, and improves the overall sanitation of the workplace, but also the collected debris can be recycled and reused, improves the utilization rate of materials, and reduces waste. The collected debris is concentrated in the hollow box, which is convenient for operators to collect the debris and reuse it. The fan not only has a certain guiding effect on the debris cut out by the cutting component of the pipe body, but also can blow compressed air to the incision of the pipe body. Polyolefin material is easy to soften or deform during high-temperature cutting. The fan blowing and cooling can effectively control the temperature of the material and avoid deformation caused by high temperature.

[0016] The chipless polyolefin pipe cutting machine designed by the utility model cooperates with the design of the hydraulic rod and the push block, so that the device can squeeze and fix the edge of the cut part of the pipe body when the cutting component cuts the pipe body, which can effectively prevent the rotating saw blade in the cutting component from driving the pipe body to rotate together. The damping block arranged on the inner end face of the push block effectively increases the friction between the push block and the surface of the pipe body, thereby improving the stability of the cutting component when cutting the pipe body to a certain extent.

[0028] As a further implementation plan of the above technical solution: the number of hydraulic rods 6 is four, and the hydraulic rods 6 are distributed at the top positions on the left and right sides of the front and rear ends below the gantry plate 4. Four through grooves are opened at the front and rear ends in the middle of the guide rail 2, and the positions and longitudinal cross-sectional shapes of the through grooves are matched with the positions and longitudinal cross-sectional shapes of the push blocks 7, so that the hydraulic rods 6 drive the corresponding push blocks 7 to push to the upper left, lower left, upper right and lower right positions of the center of the pipe body 3, respectively, to facilitate the cutting of the center of the pipe body 3 by the cutting assembly 5.

[0029] As a further implementation plan of the above technical solution: the inner end face of the push block 7 is provided with a slope inclined at thirty degrees from the upper inner side to the lower outer side, and the number of damping blocks 19 is several, and the damping blocks 19 are evenly distributed at the position of the inner end slope of the push block 7, which can effectively increase the friction between the push block 7 and the surface of the pipe body 3, and improve the stability of the cutting assembly 5 when cutting the pipe body 3 to a certain extent.

[0030] Working principle:

[0031] When using the present invention, the pipe body 3 is placed horizontally on the inner side of the guide rail 2, and the pipe body 3 is allowed to slide on the inner side of the guide rail 2 until the pipe body 3 moves to the position where it needs to be cut and stops. Then, the fan 13 and the hydraulic rod 6 are turned on. The fan 13 compresses the wind from the back of the operating table 1 and blows it to the position where the cutting assembly 5 contacts the pipe body 3, and the hydraulic rod 6 drives the push block 7 on the inner side of the gantry plate 4 to pass through the guide rail 2 and directly contact the pipe body 3. At this time, the damping block 19 on the inner end face of the push block 7 contacts After reaching the pipe body 3 and squeezing and fixing the pipe body 3, it stops, and then the cutting assembly 5 is started. The saw blade of the cutting assembly 5 cuts the pipe body 3 from top to bottom. The generated debris is blown by the fan 13 and the power generated by itself during cutting, and enters the hollow box 8 through the feed chute 15 on the rear end face of the hollow box 8. Some of the debris splashes too fast and hits the nylon mesh 10 set on the front side of the hollow box 8. At this time, part of the debris is concentrated on the nylon mesh 10, and part falls on the flip-up box at the bottom of the hollow box 8. The top of the folding plate 16 is opened, and then the wind compressed and blown out by the fan 13 is discharged forward from the exhaust port 14. After the pipe body 3 is cut, the cutting assembly 5 is lifted upward, and the guide rail 2 continues to drive the pipe body 3 to move. Similarly, when the debris in the hollow box 8 is about to overflow, the container can be placed directly below the hollow box 8, and then the folding plate 16 at the bottom of the hollow box 8 is opened. The debris inside the hollow box 8 is rotated by the folding plate 16 and falls into the container directly below the hollow box 8, and the debris attached to the nylon The operator holds the handle 12 on the top of the top plate 11 to remove the debris on the net 10. Since the top plate 11 is magnetically fixed by the magnetic block 17 inserted into the groove 18, a large force is required. When the magnetic block 17 is separated from the top plate 11, the top plate 11 drives the bottom frame plate 9 and the nylon net 10 inside the frame plate 9 to be taken out of the hollow box 8. The operator can manually clean the debris attached to the nylon net 10. Both prevent the debris from splashing and concentrate it, making it convenient for the operator to recycle the debris.

[0032] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
