[0039] Reference Figures 1-8A PVC sleeve ring cutting device that prevents debris from splashing includes a housing 14. The housing 14 is provided with a clamping and cutting assembly 1 for clamping and ring cutting PVC sleeves of different sizes. The clamping and cutting assembly 1 includes a force block 15 arranged inside the housing 14. A limit seat A18 is provided above the force block 15. An adsorption assembly 2 for collecting dust and debris is provided on one side of the limit seat A18. The adsorption assembly 2 includes a chip collecting cover 21 fixedly connected to one side of the limit seat A18. A feed pipe 23 is provided inside the chip collecting cover 21. A collection box 24 is provided at one end of the feed pipe 23 away from the chip cover 21, and a correction component 3 is provided on one side of the force block 15 to support the PVC pipe at the cutting end. When in use, the PVC pipe is placed inside the shell 14 and limited by the force block 15. When the force block 15 moves, the components inside the correction component 3 will also be driven to move, thereby clamping and limiting the part of the PVC pipe that needs to be cut. In order to prevent debris from splashing during cutting, the components inside the adsorption component 2 are started to collect the debris.

[0040] In particular, in the present invention, the adsorption component 2 also includes a feed trough 22 opened on the bottom surface of the chip cover 21. The chip cover 21 is an arc-shaped structure. One end of the feed pipe 23 is inserted into the inside of the feed trough 22, and the collection box 24 is arranged on one side of the shell 14. The end of the feed pipe 23 away from the chip cover 21 passes through the shell 14 and is inserted into the inside of the collection box 24. The inside of the collection box 24 is slidably connected with a collection drawer 25, and the collection drawer 25 and the inside of the feed pipe 23 are interconnected. When in use, the debris generated by the cutting of the PVC pipe will be blocked by the chip cover 21. Due to the shape of the chip cover 21, the debris will eventually fall to the bottom of the chip cover 21 due to gravity, and will eventually slide into the inside of the feed pipe 23 through the chip cover 21 and into the inside of the collection drawer 25 through the feed pipe 23, thereby preventing the flying debris from scratching the skin of the operator, thereby realizing the collection of debris.

[0041] In particular, in the present invention, a dust collection pipe 29 is inserted into the interior of the dust collection cover 21, and the end of the dust collection pipe 29 away from the dust collection cover 21 is inserted into the interior of the collection box 24. The interior of the collection drawer 25 is fixedly connected to a fixed frame 26, and the interior of the fixed frame 26 is fixedly connected to a flexible plate 27. A fan 28 is installed on the surface of the collection box 24, and the fan 28 and the interior of the collection box 24 are connected to each other. A dustproof net 211 is provided inside the collection box 24, and the dustproof net 211 is located below the fan 28. The inner wall of the collection box 24 is fixedly connected to a guide plate 210, and the guide plate 210 and the dust collection pipe 29 are located in the same direction, and the guide plate 210 is inclined. Pour water on the surface of the flexible plate 27, start the fan 28 while cutting, and the dust generated by the cutting of the PVC pipe will be blocked by the chip cover 21. The blocked dust will enter the interior of the collection box 24 through the dust suction pipe 29 due to the suction force of the fan 28, preventing the dust from spreading and being inhaled into the body of the operator. The dust entering the collection box 24 will first be blocked and guided by the guide plate 210 and diffused toward the flexible plate 27. The dust will no longer float due to the contact with the water on the surface of the flexible plate 27, thus realizing the collection of dust. When the fan 28 draws air from the inside of the collection box 24, the dustproof net 211 will prevent the dust from entering the interior of the fan 28.

[0042] In particular, in the present invention, the clamping and cutting assembly 1 also includes a slide groove 12 opened on the surface of the shell 14, a mounting plate 11 is inserted into the interior of the slide groove 12, the mounting plate 11 is slidably connected to the shell 14 through the slide groove 12, a motor 13 is installed on the surface of the mounting plate 11, the output shaft of the motor 13 is inserted into the interior of the force block 15 through the slide groove 12, a bevel gear A110 is provided inside the force block 15, the output shaft of the motor 13 is fixedly connected to the bevel gear A110, the surface of the bevel gear A110 is meshed with the bevel gear B112, one end of the bevel gear B112 is fixedly connected to a connecting rod 111, the connecting rod 111 passes through the surface of the shell 14, and is fixedly connected to the cutting blade 17. When in use, The motor 13 is connected to an external power source and then started. The bevel gear A110 will be driven to rotate. The bevel gear A110 will drive the connecting rod 111 to rotate through the bevel gear B112. The connecting rod 111 will drive the cutting blade 17 to rotate, so that the cutting blade 17 will cut the PVC pipe. When the force block 15 moves, it will drive the motor 13 and the mounting plate 11 to slide inside the slide groove 12. When the limit seat B19 contacts the PVC pipe, the force block 15 is still descending. The spring 115 applies force to the PVC pipe before the cutting blade 17 contacts the PVC pipe to prevent clamping and cutting from acting on the surface of the PVC pipe at the same time, causing the PVC pipe to be knocked off due to the rotational force of the cutting blade 17.

[0043] In particular, in the present invention, a limiting seat B19 is provided below the force block 15, and a plurality of positioning holes 114 are evenly provided on the surface of the limiting seat B19. The position of the force block 15 at the positioning hole 114 is fixedly connected to the limiting column 113, and the limiting column 113 is inserted into the interior of the positioning hole 114 and is slidably connected to the limiting seat B19. A spring 115 is provided inside the positioning hole 114, and the two ends of the spring 115 are respectively fixedly connected to the limiting column 113 and the limiting seat B19. An electric push rod is installed on the surface of the shell 14, and the output shaft of the electric push rod passes through the surface of the shell 14 and is fixedly connected to the force block 15. Two guide columns 16 are symmetrically fixedly connected to the inner wall of the shell 14. A guide groove is provided at the position of the force block 15 at the guide column 16. The guide column 16 is inserted into the interior of the guide groove and is slidably connected to the force block 15. The PVC pipe is placed in the limiting seat B19 and the limiting seat A18 During this time, the electric push rod is connected to the external power supply and then started. The output shaft of the electric push rod will extend toward the inside of the clamping and cutting assembly 1, and the force block 15 connected thereto will move toward the direction of the limit seat A18. The limit seat B19 will first stick to the surface of the PVC pipe, and the limit column 113 connected to the force block 15 will move inside the positioning hole 114. The spring 115 will be compressed until the force block 15 moves to a certain position and then stops. The force block 15 squeezes the limit seat B19 so that the limit seat B19 and the limit seat A18 cooperate with each other to clamp the PVC pipe and position the PVC pipe, which is convenient for subsequent ring cutting of the PVC pipe. When the force block 15 moves, in order to prevent the force block 15 from deviating during movement, the force block 15 will slide on the surface of the guide column 16 through the guide groove, so that the force block 15 can be limited by the guide column 16, thereby avoiding deviation when the force block 15 moves.

[0044] In particular, in the present invention, the adjacent sides of the limit seat B19 and the limit seat A18 are fixedly connected with a rubber roller 116, and the roller of the rubber roller 116 fits together with the PVC pipe. The surface of the connecting rod 111 is fixedly connected with a power-assisting wheel 117, and the power-assisting wheel 117 is made of rubber material. The power-assisting wheel 117 fits together with the PVC pipe. When in use, when the mounting plate 11 rotates, it will drive the power-assisting wheel 117 to rotate. Because the power-assisting wheel 117 fits together with the PVC pipe, it will drive the PVC pipe to rotate, so that the cutting blade 17 rotates in the opposite direction to the PVC pipe, and the PVC pipe will rotate on the surface of the rubber roller 116, thereby realizing the circular cutting operation of the PVC pipe.

[0045] In particular, in the present invention, the correction component 3 includes a correction seat A31 fixedly connected to the force block 15 on one side of the cutting blade 17, a correction seat B32 is provided below the correction seat A31, and the correction seat B32 is rotatably connected to the housing 14 through a rotating shaft 33. The surface of the correction seat A31 is symmetrically fixedly connected to two tooth plates A34, and the surface of each tooth plate A34 is meshed with a first gear 35. The first gear 35 is rotatably connected to the housing 14 through a bearing, and the surface of the correction seat B32 is symmetrically fixedly connected to two tooth plates B36, and the tooth plate B36 is meshed with the first gear 35. When in use, when the limit seat A18 and the limit seat B19 are When the PVC pipe is clamped, the correction seat A31 connected to the limit seat B19 will also move toward the direction of the PVC pipe. When the correction seat A31 moves, the tooth plate A34 connected to it will drive the first gear 35 to rotate inside the shell 14. The rotation of the first gear 35 will drive the correction seat B32 to rotate around the rotating shaft 33 through the tooth plate B36. The correction seat A31 and the correction seat B32 will clamp and limit the section of the PVC pipe that needs to be cut to prevent the PVC pipe from falling due to gravity when being cut, resulting in an uneven cut. The correction seat A31 and the correction seat B32 are also equipped with rubber rollers 116 for rotating the PVC pipe.

[0046] The present invention is divided into the following steps when used:

[0047] S1: When it is necessary to cut the PVC pipe, put the PVC pipe between the limit seat B19 and the limit seat A18, connect the electric push rod to the external power supply and then start it, the output shaft of the electric push rod will extend toward the inside of the clamping and cutting assembly 1, and the force block 15 connected thereto will move toward the direction of the limit seat A18, the limit seat B19 will first stick to the surface of the PVC pipe, and the limit column 113 connected to the force block 15 will move inside the positioning hole 114, the spring 115 will be compressed until the force block 15 moves to a certain position and then stops, and the force block 15 squeezes the limit seat B19, so that the limit seat B19 and the limit seat A18 cooperate with each other to clamp the PVC pipe and position the PVC pipe, which is convenient for subsequent ring cutting of the PVC pipe;

[0048] S2: When the force block 15 moves, in order to prevent the force block 15 from deflecting during movement, the force block 15 slides on the surface of the guide column 16 through the guide groove, so that the guide column 16 can limit the force block 15, thereby preventing the force block 15 from deflecting during movement;

[0049] S3: When the limiting seat A18 and the limiting seat B19 clamp the PVC pipe, the correction seat A31 connected to the limiting seat B19 will also move toward the direction of the PVC pipe. When the correction seat A31 moves, the tooth plate A34 connected thereto will drive the first gear 35 to rotate inside the housing 14. The rotation of the first gear 35 will drive the correction seat B32 to rotate with the rotating shaft 33 as the axis through the tooth plate B36. The section of the PVC pipe that needs to be cut is clamped and limited by the correction seat A31 and the correction seat B32 to prevent the PVC pipe from falling downward due to gravity when being cut, resulting in an uneven cut. The correction seat A31 and the correction seat B32 are also equipped with rubber rollers 116 for rotating the PVC pipe. When the cutting is completed, the correction seat B32 will rotate with the rotating shaft 33 as the axis, so that the correction seat B32 has a certain inclination angle, so that the cut PVC pipe can fall off naturally.

[0050] S4: When it is necessary to cut the PVC pipe, the motor 13 is connected to an external power supply and then started. The bevel gear A110 will be driven to rotate, and the bevel gear A110 will drive the connecting rod 111 to rotate through the bevel gear B112. The connecting rod 111 will drive the cutting blade 17 to rotate, so that the cutting blade 17 cuts the PVC pipe. When the force block 15 moves, it will drive the motor 13 and the mounting plate 11 to slide inside the slide groove 12. When the limit seat B19 contacts the PVC pipe, the force block 15 is still descending. The spring 115 applies force to the PVC pipe before the cutting blade 17 contacts the PVC pipe, preventing the clamping and cutting from acting on the surface of the PVC pipe at the same time, causing the PVC pipe to be knocked off due to the rotational force of the cutting blade 17.

[0051] S5: When the mounting plate 11 rotates, the power-assisting wheel 117 is driven to rotate. Since the power-assisting wheel 117 and the PVC pipe are in contact with each other, the PVC pipe is driven to rotate, so that the cutting blade 17 rotates in the opposite direction to the PVC pipe. The PVC pipe rotates on the surface of the rubber roller 116, thereby achieving a circular cutting operation on the PVC pipe.

[0052] S6: The debris generated by cutting the PVC pipe will be blocked by the debris cover 21. Due to the shape of the debris cover 21, the debris will eventually fall to the bottom of the debris cover 21 due to gravity, and finally slide through the debris cover 21 into the inside of the feed pipe 23 and into the inside of the collection drawer 25, preventing the flying debris from scratching the skin of the operator, thus achieving the collection of the debris;

[0053] S7: Pour water on the surface of the flexible plate 27, and start the fan 28 while cutting. The dust generated by the cutting of the PVC pipe will be blocked by the chip cover 21. The blocked dust will enter the interior of the collection box 24 through the dust suction pipe 29 due to the suction force of the fan 28, preventing the dust from spreading and being inhaled into the body of the operator. The dust entering the collection box 24 will first be blocked and guided by the guide plate 210 and diffused toward the flexible plate 27. The dust will no longer float due to the contact with the water on the surface of the flexible plate 27, thus realizing the collection of dust. When the fan 28 draws air from the interior of the collection box 24, the dustproof net 211 will prevent the dust from entering the interior of the fan 28.

[0054] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
