Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic pipe processing, and more specifically to a manual cutting and chip removal device for plastic pipes. Background Art
[0002] Plastic pipes are commonly used construction materials in various fields such as industry, agriculture, municipal administration and construction. Most existing plastic pipes are standardized and produced in large quantities with fixed and uniform specifications and sizes. However, in actual production applications, because the requirements for pipe length are not fixed for establishing different plastic pipe systems, the length of plastic pipes is usually processed secondary according to actual needs. In order to flexibly control the cutting length, manual cutting is often used. This process will generate a large amount of chips, which will not only pollute the production environment, but also harm the health of operators. Existing chip removal technologies are mostly focused on the chip removal research of automatic cutting machines, and the relevant technology is not suitable for manual cutting machines. Therefore, it is necessary to develop a chip removal device for manual plastic pipe cutting machines to eliminate the impact of chips on the production environment and the health of operators during pipe cutting.
[0003] There is a Chinese utility model, publication number CN218255387U, which discloses a PE pipe cutting device, including a cutting assembly, a placement seat and a support seat, and a dust collecting box is fixedly connected to the top of the support seat. The utility model installs a dust collecting device with an air pump as the main output part, so that when the PE pipe is cut by the cutting machine, some fine pipe residues generated by it will be recovered into the dust collecting box through the air pump, reducing the impact of the splashing of pipe residues on the operator when cutting the pipe, and indirectly improving the safety of the operator when cutting the pipe.
[0004] In the above scheme, the cutting position of the cutting pipe is in a completely open position, and the debris generated by the pipe cutting is easy to spread around. The pipe debris is only sucked into the dust collection box by an air pump, which can only collect the debris generated by the cutting from one direction, and the dust collection effect cannot be guaranteed. Utility Model Content
[0005] In order to solve the above problems, the utility model provides a manual plastic pipe cutting and chip removal device, which adds a dust collection structure and a dust suction device. The dust collection structure blocks the debris generated when the plastic pipe is cut and collects it into a limited space, which is then sucked into the closed space by the dust suction device.

[0007] In the technical solution, when a manual cutter is used to cut a pipe, the debris generated by the pipe will fly out along the tangent direction of the blade rotating at the cutting point. After the debris flies out, it will be blocked by the dust collection structure and collected in a limited space, and then absorbed by the dust collection device, thereby preventing the debris from being discharged into the environment.
[0008] Preferably, the dust collection structure includes a dust cover, a dust collection hole and a dust collection funnel; the dust cover is installed on the material table and covers the manual cutting machine, and the open structure is formed on the dust cover; the upper surface of the material table is provided with a dust collection hole; the dust collection hole is located below the manual cutting machine; the dust collection funnel is arranged below the dust collection hole.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0023] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:
[0024] Example 1
[0025] like Figure 1 As shown, a manual cutting and chip removal device for plastic pipes includes a material table 1 and a manual cutting machine 2; the manual cutting machine 2 is installed on the upper surface of the material table 1; and also includes a dust collecting structure 3 and a dust suction device 4; the dust collecting structure 3 is installed on the material table 1 and covers the manual cutting machine 2, and the dust collecting structure 3 has an open structure for operating the manual cutting machine 2; the dust collecting structure 3 is connected to the dust suction device 4. The manual cutting machine 2 is installed on the material table 1. On the one hand, it avoids the need for workers to bend down continuously when the manual cutting machine 2 is placed on the ground to cut the pipe, which increases the labor load of the workers; on the other hand, the manual cutting machine 2 is set up using the material table 1, and the space under the manual cutting machine 2 can be used to install the dust collecting structure 3. The dust collecting structure 3 is provided with an open structure while ensuring the blocking of pipe debris, leaving an operating space for workers to operate the manual cutting machine 2. The debris generated by cutting the pipe will be blocked by the dust collecting structure 3 after flying out, and will be collected in a limited space, and then absorbed by the dust suction device 4, avoiding the discharge of debris into the environment.
[0026] like Figure 1 As shown, the dust collecting structure 3 includes a dust cover 301, a dust collecting hole 302 and a dust collecting funnel 303; the dust cover 301 is installed on the material platform 1 and covers the manual cutting machine 2, and the open structure is formed on the dust cover 301; the upper surface of the material platform 1 is provided with a dust collecting hole 302; the dust collecting hole 302 is located below the manual cutting machine 2; and the dust collecting funnel 303 is provided below the dust collecting hole 302. When cutting the pipe, the dust cover 301 covers the manual cutting machine 2, forming a semi-enclosed space around the manual cutting machine 2, and the generated debris is blocked by the dust cover 301 after flying out, and can only exist in the dust cover 301. A dust collecting hole 302 is provided below the manual cutting machine 2 covered by the dust cover 301, and the debris falls into the dust collecting funnel 303 through the dust collecting hole 302 under the action of its own gravity, so that the debris generated by cutting the pipe is collected in the dust collecting funnel 303.
[0027] like Figure 1As shown, the front side of the dust cover 301 is an open structure; the bottom surface of the dust cover 301 is an open structure in the part that contacts the material platform 1 and the dust collecting funnel 303. The front side of the dust cover 301 faces the operating position of the manual cutter 2. The front side of the dust cover 301 is opened to leave space for placing the manual cutter 2, leaving operating space for workers, and providing a channel for the debris generated after the pipe cutting to enter the dust cover 301. When cutting the pipe, the debris generated by the cutting will fly out along the tangent direction of the blade rotating at the cutting point under the drive of the blade of the manual cutter 2, and the direction is toward the rear side of the dust cover 301. Therefore, the opening of the front side of the dust cover 301 will not affect the dustproof effect of the dust cover 301. The position of the front side of the dust cover 301 on the material platform 1 does not exceed the cutting point when the manual cutter 2 cuts the plastic pipe in the direction toward the operator, which ensures that the dust cover 301 will not interfere with the placement and movement of the cut plastic pipe. The bottom surface of the dust cover 301 is an open structure in the part that contacts the material platform 1 and the dust collecting funnel 303. On the one hand, it saves the amount of material required to make the dust cover 301. On the other hand, the debris generated after cutting the pipe will fall under the action of its own gravity. The bottom of the dust cover 301 is open in the part that contacts the material platform 1 and the dust collecting funnel 303, which ensures the blocking effect on the debris while also providing space for the debris to fall into the dust collecting funnel 303.
[0028] like Figure 1 As shown, the dust cover 301 protrudes from the outer edge of the material platform 1, and the dust cover 301 protruding from the outer edge of the material platform 1 is connected to the dust collecting funnel 303. When cutting a plastic pipe, the debris generated by the cutting is driven by the blade of the manual cutter 2 and flies out along the tangent direction of the blade rotating at the cutting point, with a certain initial velocity. After colliding with the rear side of the dust cover 301, the debris may be rebounded and fly out from the front side of the dust cover 301, directly toward the operator, causing adverse effects on the work of cutting the plastic pipe. Protruding the dust cover 301 from the outer edge of the material platform 1 increases the depth of the internal space of the dust cover 301, so that the debris generated after cutting the pipe collides with the rear side of the dust cover at a smaller speed. The debris rebounded after the collision needs to fly a longer distance to leave the dust cover 301, thereby enhancing the dustproof effect of the dust cover 301. Some of the debris that collides with the rear side of the dust cover 301 can directly fall into the dust collecting funnel 303 through the part of the dust cover 301 that protrudes from the outer edge of the material platform 1 and is connected to the dust collecting funnel 303.
[0029] like Figure 1As shown, a fixed rod is straddled on the dust collecting hole 302, and the manual cutter 2 is installed in the dust collecting hole 302 through the fixed rod 3021. Both ends of the fixed rod 3021 are fixed on the table top of the material table 1, straddled on the dust collecting hole 302, forming a hollow structure, and the manual cutter 2 is fixed on the fixed rod 3021, so that the manual cutter 2 can be set above the dust collecting hole 302, and the unsplashed debris generated when cutting the pipe can directly fall into the dust collecting funnel 303 through the dust collecting hole 302. The splashed debris that falls on the non-open structure of the table top of the material table 1 and the bottom of the dust cover 2 can be directly swept into the dust collecting hole 302.
[0030] like Figure 1 As shown, the fixing rod 3021 spans across the center of the dust collecting hole 302. The dust collecting hole 302 is the bottom surface of the manual cutter 2, and the manual cutter 1 is fixed on the fixing rod 3021. The fixing rod 3021 spans across the center of the dust collecting hole 302, and the manual cutter 1 is also located in the center of the dust collecting hole 302. The bottom surface of the manual cutter 2 and the dust collecting hole 302 form a hollow structure. When the manual cutter 1 is used to cut plastic pipe fittings, the bottom cutting point is located in the center of the dust collecting hole 302. When the cutting generates debris, no matter which direction the debris falls, it can fall into the dust collecting funnel 303 through the hollow structure formed by the bottom surface of the manual cutter 2 and the dust collecting hole 302.
[0031] Example 2
[0032] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 2 As shown, the dust collecting funnel 303 has a funnel opening; the funnel opening is located below the dust collecting hole 302; an inclined plate 3031 inclined toward the bottom of the dust collecting funnel 303 is arranged in the dust collecting funnel 303; and the rear side of the dust collecting funnel 303 is aligned with the rear side of the dust cover 301. The debris generated when cutting the plastic pipe falls onto the inclined plate 3031 in the dust collecting funnel 303 through the funnel opening of the dust collecting funnel 303. The inclined plate 3031 is inclined toward the bottom of the dust collecting funnel 303, and the debris on the inclined plate 3031 slides down along the inclined direction of the inclined plate 3031 under the action of its own gravity, so that the debris in the dust collecting funnel 303 is concentrated in a certain range at the bottom of the dust collecting funnel 303. The rear side of the dust collecting funnel 303 is aligned with the rear side of the dust cover 301, which ensures the closedness of the dust cover 301, and prevents debris from entering the device through the gap between the rear side of the dust cover 301 and the rear side of the dust collecting funnel 303, thereby affecting the dust collection effect. On the other hand, the funnel opening of the dust collecting funnel 303 and the bottom surface of the dust cover 301 form a hollow structure, so that in addition to the dust collecting hole 302 set on the material table 1, a channel for debris to fall into the dust collecting funnel 303 is added, thereby obtaining a better dust collection effect.
[0033] like Figure 2As shown, a dust suction hole 3032 is provided on the rear side of the dust collecting funnel 303. The rear side of the dust collecting funnel 303 is close to the bottom of the inclined plate 3031, and the debris generated by cutting the plastic pipe fittings is mostly concentrated in this part under the action of its own gravity. Since a funnel opening is provided above the dust collecting funnel 303, which is a semi-open structure, the collected debris is easy to overflow from the funnel opening. The dust suction hole 3032 is provided on the rear side of the dust collecting funnel 303, so that the concentrated debris can be easily sucked in through the dust suction hole 3032 for further processing.
[0034] like Figure 1 As shown, the dust collecting device 4 includes a chip discharge duct 401, a dust collecting driver 402 and a dust collecting box 403; one end of the chip discharge duct 401 is connected to the dust collecting hole 3032 of the dust collecting funnel 303; the other end of the chip discharge duct 401 is connected to the air suction end of the dust collecting driver 402; the air outlet end of the dust collecting driver 402 is connected to the dust collecting box 403. The dust collecting driver 402 is connected to the dust collecting funnel 303 through the chip discharge duct 401, and the dust collecting driver 402 transmits the suction force to the dust collecting funnel 303 through the chip discharge duct 401, which will generate an air flow field in the semi-enclosed space of the dust collecting funnel 303, so that the debris gradually gathers to the dust collecting hole 3032 under the action of the air flow field, away from the cutting machine operator and the funnel mouth of the dust collecting funnel 303, and finally the debris is sucked into the dust collecting box 404 through the chip discharge duct 401. The dust box 404 is a closed space, and debris cannot enter the external environment after entering the dust box 404.
[0035] Example 3
[0036] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 1 As shown, a replaceable dust bag is installed in the dust box 403. The dust bag is inexpensive and can be directly used as a carrier for collecting and transporting debris. After the dust bag is filled with debris, it is only necessary to tighten the opening of the dust bag and then directly take it out of the dust box 404 for carrying and processing the debris, and then a new dust bag is installed in the dust box 404 to continue working, thereby realizing efficient centralized processing of debris generated by cutting plastic pipe fittings.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
