Description

Technical Field

[0001] This application relates to the technical field of plastic hose processing equipment, and in particular to a pipe cutting machine for plastic production. Background Technology

[0002] Plastic products are a general term for household and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a class of synthetic polymer materials with malleability. Compared to metals, stone, and wood, plastic products have advantages such as low cost and high malleability, and are widely used in the national economy. The plastics industry occupies an extremely important position in the world today.

[0003] Plastic pipes are produced using extrusion molding, which is generally a continuous process, resulting in relatively long pipes. Therefore, plastic processing includes a cutting step, typically using a pipe cutter to cut the pipes into appropriately sized flexible hoses.

[0004] Because the plastic hose is made of a relatively soft material, the discharge end needs to be supported during the cutting process to improve cutting accuracy and product quality. However, after the hose is cut, workers still need to manually remove the long plastic hose from the discharge end, which increases the labor intensity of workers and is not conducive to improving production efficiency. Therefore, this needs to be improved. Utility Model Content

[0005] To facilitate the cutting of plastic pipes and reduce the labor intensity of workers, this application provides a pipe cutting machine for plastic production.

[0006] The technical solution of the pipe cutting machine for plastic production provided in this application is as follows:

[0007] A pipe cutting machine for plastic production includes a base, a first positioning component, a traction component, a second positioning component, and a pipe cutting component. The first positioning component, the traction component, and the second positioning component are sequentially arranged on the base along the conveying direction of the plastic pipe. The first positioning component and the second positioning component are both used to position the plastic pipe. The traction component is used to convey the plastic pipe. The second positioning component has a slit. The pipe cutting component is located above the slit and is used to cut the plastic pipe inside the second positioning component.

[0008] By adopting the above technical solution, the end of the plastic tube passes sequentially through the first positioning component, the traction component, and the second positioning component. Both the first and second positioning components serve to position the plastic tube. The tube cutting component can cut the plastic tube, thereby producing shorter plastic tubes. After cutting, the traction component relies on friction to transport the plastic tube, causing the uncut plastic tube to move and push out the already cut plastic tube, achieving continuous cutting production, improving production efficiency, and reducing the labor intensity of personnel.

[0009] Preferably, the first positioning component includes a first positioning tube and a second positioning tube, which are arranged sequentially along the moving direction of the plastic tube. The first positioning tube has a first positioning groove for supporting the plastic tube, and the second positioning tube has a second positioning groove for positioning the plastic tube.

[0010] By adopting the above technical solution, the end of the plastic tube is inserted sequentially from the first positioning tube and the second positioning tube. The first positioning groove and the second positioning groove can position the plastic tube to ensure that the plastic tube is not easily shifted when it is cut.

[0011] Preferably, the traction assembly includes a first conveyor seat, a second conveyor seat, and a conveyor belt. The first conveyor seat and the second conveyor seat are arranged vertically opposite each other, and the conveyor belt is rotatably connected to both the first conveyor seat and the second conveyor seat. The two conveyor belts are used to transport plastic pipes.

[0012] By adopting the above technical solution, two conveyor belts arranged opposite each other clamp the plastic pipe, and the pipe is conveyed by contact friction, thus achieving the linear movement of the pipe.

[0013] Preferably, the second positioning component includes a third positioning tube and a fourth positioning tube, which are arranged sequentially along the moving direction of the plastic tube. The cut is located between the third positioning tube and the fourth positioning tube. The third positioning tube has a third positioning groove, and the fourth positioning tube has a fourth positioning groove. The plastic tube passes through both the third positioning groove and the fourth positioning groove.

[0014] By adopting the above technical solution, the plastic tube passes through the third positioning tube and the fourth positioning tube, and the third positioning groove and the fourth positioning groove can play a positioning role for the plastic tube.

[0015] Preferably, the pipe cutting assembly includes a drive unit, a lifting seat, and a cutter. The lifting seat is raised and lowered, and the cutter is disposed on the lifting seat and located directly above the cut. The drive unit is connected to the lifting seat and is used to control the up and down movement of the lifting seat.

[0016] By adopting the above technical solution, the drive unit controls the lifting seat to move downwards, and the cutter follows downwards, thereby completing the cutting of the plastic tube.

[0017] Preferably, it further includes a fixing block, which is disposed on the machine base and has several of them. The second positioning tube, the third positioning tube and the fourth positioning tube can be detachably disposed on the fixing block. The vertical distance between the first conveyor seat and the second conveyor seat can be adjusted.

[0018] By adopting the above technical solution, when it is necessary to limit the movement of plastic pipes of different diameters, the second, third, and fourth positioning pipes with correspondingly sized positioning grooves can be replaced. At the same time, the distance between the first and second conveying seats is also adjusted accordingly to ensure the conveying of the plastic pipes.

[0019] Preferably, the fixing block has a slot for limiting the positioning tube, and the positioning tube is fastened to the fixing block by fasteners.

[0020] By adopting the above technical solution, the slot can increase the contact area between the fixing block and the positioning tube, thereby improving the stability of the positioning tube.

[0021] Preferably, it also includes a swing arm and a sensor. The swing arm is located between the first positioning tube and the second positioning tube. One end of the swing arm is rotatably connected to the base, and the other end rests on the outer wall of the plastic tube. The sensor is located on the base. The end of the swing arm connected to the base is connected to the sensor. The end of the swing arm resting on the plastic tube will naturally hang down under its own weight.

[0022] By adopting the above technical solution, in the initial state, when the plastic pipe is inserted into the frame, the swing arm is pushed upward so that it rests on the plastic pipe. As the cutting work continues, the uncut plastic pipe will become shorter and shorter. When the entire plastic pipe is almost cut, there will be no plastic pipe between the first positioning tube and the second positioning tube. The swing arm will fall naturally under the action of gravity. The sensor detects the natural fall of the swing arm and can determine that the plastic pipe cutting work is over. The machine can be stopped or an alarm can be issued.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] (1) By setting up a first positioning component, a traction component, a second positioning component and a pipe cutting component, the first positioning component and the second positioning component play a role in positioning the plastic pipe, and the pipe cutting component cuts the plastic pipe to cut out a shorter plastic pipe. After cutting, the traction component relies on friction to transport the plastic pipe, and the uncut plastic pipe moves to push out the already cut plastic pipe, thereby realizing continuous cutting production.

[0025] (2) By setting up a swing arm and a sensor, the plastic pipe can be detected to determine whether the plastic pipe has been completely cut, thereby controlling the equipment to stop or issuing an alarm to remind the surrounding staff. Attached Figure Description

Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0034] This application discloses a pipe cutting machine for plastic production. (Refer to...) Figure 1 and Figure 2 The pipe cutting machine includes a base 1, a first positioning component 2, a traction component 3, a second positioning component 4, and a pipe cutting component 5. The base 1 is fixedly installed on the ground. The first positioning component 2, the traction component 3, and the second positioning component 4 are sequentially arranged on the base 1 along the conveying direction of the plastic pipe, with the traction component 3 located between the first positioning component 2 and the second positioning component 4. Both the first positioning component 2 and the second positioning component 4 are used to position the plastic pipe, and the traction component 3 is used to convey the plastic pipe. A notch 6 is provided on the second positioning component 4, and the pipe cutting component 5 is installed above the notch 6 to cut the plastic pipe inside the second positioning component 4.

[0035] The end of the plastic tube passes sequentially through the first positioning component 2, the traction component 3, and the second positioning component 4. Both the first positioning component 2 and the second positioning component 4 serve to position the plastic tube. The tube cutting component 5 can cut the plastic tube, thereby cutting out shorter plastic tubes. After cutting, the traction component 3 uses friction to transport the plastic tube, causing the uncut plastic tube to move and push out the already cut plastic tube, realizing continuous cutting production, improving production efficiency, and reducing the labor intensity of personnel.

[0036] Specifically, the first positioning component 2 includes a first positioning tube 21 and a second positioning tube 22, which are sequentially arranged along the moving direction of the plastic tube. The second positioning tube 22 is located between the first positioning tube 21 and the traction component 3. The first positioning tube 21 has a first positioning groove extending through it, the inner diameter of which is larger than the outer diameter of the plastic tube. The plastic tube passes through the first positioning groove, and the first positioning tube 21 supports the plastic tube. The second positioning tube 22 has a second positioning groove extending through it, the inner diameter of which is slightly larger than the outer diameter of the plastic tube to be cut. The second positioning groove is used to position the plastic tube. The end of the plastic tube passes sequentially through the first positioning tube 21 and the second positioning tube 22. The first and second positioning grooves can position the plastic tube to ensure that its position does not easily shift when it is cut.

[0037] The traction assembly 3 includes a first conveyor seat 31, a second conveyor seat 32, and a conveyor belt 33. The first conveyor seat 31 and the second conveyor seat 32 are arranged vertically opposite each other, with the first conveyor seat 31 located above the second conveyor seat 32. A conveyor belt 33 is rotatably connected to both the first conveyor seat 31 and the second conveyor seat 32. The plastic tube passes between the two conveyor belts 33, which are used to transport the plastic tube. The two conveyor belts 33 cooperate to clamp the plastic tube, relying on pressure and friction to achieve the effect of transporting the tube and realizing the linear movement of the tube.

[0038] The second positioning component 4 includes a third positioning tube 41 and a fourth positioning tube 42, which are arranged sequentially along the moving direction of the plastic tube. The third positioning tube 41 is located between the fourth positioning tube 42 and the traction component 3. The cut 6 is located between the third positioning tube 41 and the fourth positioning tube 42. A third positioning groove is formed through the third positioning tube 41, and a fourth positioning groove is formed through the fourth positioning tube 42. The inner diameter of both the third and fourth positioning grooves is slightly larger than the outer diameter of the plastic tube, and the plastic tube passes through both the third and fourth positioning grooves simultaneously.

[0039] The pipe cutting assembly 5 includes a drive unit 51, a lifting seat 52, and a cutter 53. The lifting seat 52 is flexibly mounted on the machine base 1. The cutter 53 is bolted to the lifting seat 52 and is located directly above the cutting opening 6, allowing the cutter 53 to be detachable. The drive unit 51 is connected to the lifting seat 52 and controls the up-and-down movement of the lifting seat 52. The drive unit 51 is a pneumatic cylinder or a hydraulic cylinder, and the lifting seat 52 is mounted on the piston rod of the pneumatic or hydraulic cylinder. During cutting, the drive unit 51 controls the lifting seat 52 to move downwards, and the cutter 53 follows, thus completing the cutting of the plastic pipe.

[0040] The base 1 is equipped with several fixing blocks 7. In this embodiment, there are three fixing blocks 7, and the second positioning tube 22, the third positioning tube 41, and the fourth positioning tube 42 are detachably mounted on the three fixing blocks 7. The fixing blocks 7 have arc-shaped slots for limiting the positioning of each block. The positioning tubes are secured to the fixing blocks 7 by fasteners 8, which are fastening bolts or studs. The vertical distance between the first conveyor seat 31 and the second conveyor seat 32 is adjustable. A cylinder can be used to control the vertical movement of either the first or second conveyor seat 31, thereby changing the distance between the two conveyor belts 33. When it is necessary to limit the movement of plastic pipes of different diameters, the second, third, and fourth positioning tubes 42 with correspondingly sized positioning slots can be replaced. Simultaneously, the distance between the first conveyor seat 31 and the second conveyor seat 32 is also adjusted adaptively to ensure the conveying of plastic pipes of different diameters.

[0041] In addition, a swing arm 9 and a sensor 10 are respectively installed on the frame. The swing arm 9 is located between the first positioning tube 21 and the second positioning tube 22. One end of the swing arm 9 is rotatably connected to the base 1, and the other end is used to rest on the outer wall of the plastic tube. The sensor 10 is fixed to the base 1. The end of the swing arm 9 connected to the base 1 is connected to the sensor 10, and the end of the swing arm 9 resting on the plastic tube will naturally hang down under its own weight.

[0042] In the initial state, when the plastic pipe is inserted into the frame, the swing arm 9 is pushed upwards so that it rests on the plastic pipe. As the cutting work continues, the uncut plastic pipe will become shorter and shorter. When the entire plastic pipe is almost cut, there will be no plastic pipe between the first positioning tube 21 and the second positioning tube 22. The swing arm 9 will fall naturally under the action of gravity. The sensor 10 detects the natural fall of the swing arm 9 and can determine that the plastic pipe cutting work is over. The machine can be stopped or an alarm can be issued to remind the surrounding staff.

[0043] The implementation principle of a plastic pipe cutting machine in this embodiment is as follows: the end of the plastic pipe passes sequentially through a first positioning component 2, a traction component 3, and a second positioning component 4. Both the first positioning component 2 and the second positioning component 4 serve to position the plastic pipe. The pipe cutting component 5 can cut the plastic pipe, thereby cutting out shorter plastic pipes. After cutting, the traction component 3 uses friction to transport the plastic pipe, causing the uncut plastic pipe to move and push out the already cut plastic pipe, realizing continuous cutting production, improving production efficiency, and reducing the labor intensity of personnel.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
