Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to a HDPE pipe cutting device, and belongs to the technical field of HDPE pipes. Background Art

[0002] HDPE is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin cross section. PE has excellent resistance to most domestic and industrial chemicals. Certain types of chemicals will produce chemical corrosion, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance. It can be used for packaging purposes. HDPE has good electrical properties, especially high dielectric strength of insulation, which makes it very suitable for wires and cables. Medium to high molecular weight grades are impact resistant, which is the case at room temperature or even at low temperatures of -40F;

[0003] A Chinese patent publication (publication number: CN 212859689 U) discloses a HDPE pipe cutting device, which relates to the field of pipe cutting technology, in order to solve the problem that the pipe is prone to shaking during the existing pipe cutting process, which increases the difficulty of cutting for the staff, and the shaking will cause the incision of the pipe body to be uneven. The HDPE pipe cutting device includes an adjustment mechanism, a limit mechanism, a fixed clamp mechanism, and a movable clamp mechanism, and the adjustment mechanism is slidably connected inside the frame mechanism. First, determine the length of the pipe groove to be cut, and then adjust the distance between the second clamp base at the upper end of the card plate and the first clamp base at the front end of the top of the bracket through the cooperation of the rack, the driven gear, and the driving gear. Next, the first jacket is opened by the cooperation of the right rotating shaft, and then the second jacket is opened by the cooperation of the right rotating shaft. Next, one end of the pipe is placed in the clamp groove of the first clamp base, and then the other end of the pipe is placed in the clamp groove of the second clamp base.

[0004] However, when cutting the pipe, the operator is required to move the pipe to the cutting device. As described in the above case, the size of the pipe is often large, so the operator is often more laborious when moving the pipe. At the same time, moving the pipe will also take a certain amount of time, which will in turn affect the overall cutting speed, waste more manpower, and reduce the cutting efficiency. For this reason, a HDPE pipe cutting device is proposed. Utility Model Content

By setting the limiting groove, the movement of the screw block can be limited to prevent it from rotating synchronously with the thread on the surface of the screw rod during movement.

DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-4 As shown, the embodiment of the utility model provides a HDPE pipe cutting device, including a bottom plate 1, a vertical plate 4 is fixedly installed on both the front and rear sides of the top of the bottom plate 1, a mounting plate 5 is fixedly installed on the left side of the vertical plate 4, a cutting blade 6 is movably connected to the inner side of the mounting plate 5, an L-shaped plate 7 is fixedly installed on the front side of the outer side of the vertical plate 4, and a pipe body 8 is arranged on the inner side of the vertical plate 4;

[0028] A material transport mechanism 2 is provided on the front side of the L-shaped plate 7, and the material transport mechanism 2 includes a servo motor 201, and the output end of the servo motor 201 is fixedly connected to a driving shaft 202, and the right side of the front side of the vertical plate 4 is movably connected to a driven shaft 203, and the outer surfaces of the driven shaft 203 and the driving shaft 202 are movably connected to a transmission belt 204, and the rear sides of the driving shaft 202 and the driven shaft 203 are fixedly connected to connecting rods 205, and the front and rear sides of the outer surface of the connecting rod 205 are fixedly installed with connecting blocks 206, the outer side of the connecting block 206 is movably connected to a mounting block 207, and the top of the mounting block 207 is fixedly installed with a top plate 208.

[0029] By setting up the material transport mechanism 2, the pipes can be transported automatically, which saves the time and manpower of operators in transporting the pipes by themselves, shortens the time spent on transporting the plates, improves the overall speed of pipe cutting, and avoids the operator transporting the pipes by themselves, which takes a long time and reduces the overall cutting efficiency.

[0030] Example 2

[0031] In one embodiment, a movable groove 211 is opened on the inner side of the vertical plate 4, a movable rod 212 is fixedly installed on the outer side of the mounting block 207, and the outer side of the movable rod 212 is slidably connected to the inner cavity of the movable groove 211. A support plate 209 is fixedly installed on the top of the top plate 208, and a support block 210 is fixedly installed on the top of the vertical plate 4. The outer surfaces of the support plate 209 and the support block 210 are bonded with rubber. A protective mechanism 3 is provided on the top of the bottom plate 1. The protective mechanism 3 includes a bidirectional motor 301, which is fixedly installed at the middle end of the top of the bottom plate 1. The output ends of the front and rear sides of the bidirectional motor 301 are fixedly connected with a screw rod 302 through a rotating shaft. The outer surface of the screw rod 302 is threadedly connected with a screw block 303. An L-shaped rod 304 is fixedly installed on the top of the screw block 303, and a baffle 305 is fixedly installed on the inner side of the L-shaped rod 304.

[0032] By setting the moving rod 212 and the moving groove 211, the moving direction of the installation block 207 can be limited, thereby avoiding the problem that the support plate 209 cannot automatically transport the pipe on the top of the support block 210 to the left. By setting the support plate 209 and the support block 210, the pipe can be supported. Due to the rubber bonded on the surface, scratches on the surface of the pipe due to friction can be avoided when the pipe is transported. By setting the protection mechanism 3, the pipe in transportation can be protected to avoid the pipe falling from the top of the support block 210 and the support plate 209 to the ground during transportation, causing damage to the pipe.

[0033] Example 3

[0034] In one embodiment, an insert rod 307 is fixedly installed on the left and right sides of the outer side of the vertical plate 4, a circular groove 306 is opened on the left and right sides of the baffle 305, the insert rod 307 is movably connected in the inner cavity of the circular groove 306, a limiting plate 308 is fixedly installed on the outer side of the screw rod 302, and the diameter of the limiting plate 308 is larger than the diameter of the inner side of the screw block 303, and limiting grooves 309 are opened on the front and back sides of the top of the bottom plate 1, and the bottom of the screw block 303 is slidably connected in the inner cavity of the limiting groove 309.

[0035] By providing the insertion rod 307 and the circular groove 306, the baffle 305 can be supported and its moving direction can be limited, so as to avoid the baffle 305 being unable to protect all the pipe bodies 8 due to directional deviation when moving. By providing the limiting plate 308, it can be avoided that the screw block 303 falls off the surface of the screw rod 302 when moving outward, and then the spacing on the inner side of the baffle 305 cannot be adjusted, resulting in the inability to protect the pipe. By providing the limiting groove 309, the movement of the screw block 303 can be limited, so as to avoid it rotating synchronously with the thread on the surface of the screw rod 302 during movement.

[0036] When the utility model is working: the output end of the bidirectional motor 301 drives the screw rod 302 to rotate, and through the mutual cooperation with the screw block 303, the L-shaped rod 304 and the baffle 305 move inward synchronously, which can protect the pipes of different lengths. Then the output end of the servo motor 201 drives the active shaft 202 to rotate, and through the mutual cooperation with the driven shaft 203 and the transmission belt 204, the connecting rod 205 drives the connecting block 206 to rotate. At this time, the mounting block 207 moves in a circle through the rotation of the connecting block 206, and the top plate 208 and the support plate 209 move in a circle synchronously. When the support plate 209 moves in a circle to the top, the pipe body 8 can be lifted from the top of the support block 210, and by moving in a circle to the lower left, the pipe body 8 can be gradually moved to the left, and then the automatic material transportation of the pipe body 8 is completed.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
