Description

Technical Field

[0001] This application relates to the field of PVC pipe technology, specifically to a PVC pipe equipment. Background Technology

[0002] PVC pipes are made from polyvinyl chloride as the main raw material, with the addition of stabilizers, lubricants and other additives, and are formed by hot pressing. PVC pipes are characterized by their light weight, corrosion resistance and high pressure resistance. PVC pipes can be divided into two types: rigid and flexible. Rigid PVC pipes are commonly used in building pipes, doors and windows, while flexible PVC pipes are used in pipelines, cable insulation, flooring and other fields. During the production and processing of PVC pipes, cutting equipment is required to cut the PVC pipes.

[0003] A search revealed Chinese patent CN221186673U, which discloses a PVC pipe cutting device. The device includes a base, a first electric push rod at the bottom of the base, a support at the output end of the first electric push rod, a driving device at the top of the support, and a cutting blade at the output end of the driving device. A baffle is located at one end of the support, and a cutting table is located on the top of the baffle. A dust removal device is located on one side of the baffle. The top of the cutting table has a storage structure, a material storage tank, and a cutting groove. In this invention, the cutting blade is controlled to rotate by a motor and a pulley, and the support is controlled by the first electric push rod. The device moves up and down to cut PVC pipes; the cutting blade is not exposed to the outside, reducing operational risks and ensuring safety; a dust removal device can collect dust during cutting, maximizing dust absorption; and pipe storage ensures a clean cutting table and improves cutting efficiency. However, this invention lacks a positioning device for PVC pipes during cutting. Therefore, if the PVC pipe shifts during cutting, the aesthetics of the cut will be greatly reduced, and the cutting efficiency will also decrease. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a PVC pipe cutting device that has advantages such as the ability to position PVC pipes. This solves the problem that when cutting PVC pipes, the lack of a positioning device for the PVC pipes leads to displacement of the PVC pipes during cutting, which greatly reduces the aesthetics of the cut and the efficiency of PVC pipe cutting.

[0005] To achieve the above objectives, this application provides the following technical solution: a PVC pipe equipment, including a support platform, a support frame fixed in the middle of the upper surface of the support platform, a cylinder fixed in the lower surface of the support frame, a drive motor fixed in the lower surface of the piston rod of the cylinder, a cutting blade fixed in the output shaft of the drive motor, a positioning mechanism for positioning PVC pipes provided in the middle of the inner bottom wall of the support platform, and a dust collection mechanism for dust collection provided at the bottom left side of the support frame;

[0006] The positioning mechanism includes a dual-axis motor, two worm gears, two bidirectional screws, two worm wheels, four threaded sleeves, four connecting blocks, and four arc-shaped clamping plates. The dual-axis motor is fixed in the middle of the inner bottom wall of the support platform. The two worm gears are respectively fixed to the two output shafts on the left and right sides of the dual-axis motor. The two bidirectional screws are respectively rotatably connected to the top of the left and right ends of the opposite side of the front and rear side walls of the inner cavity of the support platform through bearings. The worm wheels are fixed in the middle of the outer surface of the bidirectional screws and are meshed with the worm gears. The threaded sleeves are threadedly connected to the bidirectional screws. The connecting blocks are fixed on the upper surface of the threaded sleeves. One end of the upper surface of the connecting blocks is fixed through and extends to the upper side of the support platform. The arc-shaped clamping plates are fixed on the upper surface of the connecting blocks.

[0007] By adopting the above technical solution, the positioning mechanism can ensure the PVC pipe is fixed during cutting, preventing it from shifting due to unstable placement. This greatly improves the cutting effect and aesthetics of PVC pipes, while also increasing the efficiency of PVC pipe cutting and further enhancing its practicality.

[0008] Furthermore, the cross-sectional shape of the support frame is an inverted L-shape, and the shape of the support platform is a hollow cuboid.

[0009] Furthermore, the two worm gears are rotatably connected to the side opposite to the inner wall of the support platform via bearings, and the two bidirectional screws are symmetrically distributed on the left and right sides of the vertical central axis of the support platform.

[0010] By adopting the above technical solution, it is ensured that the worm gear rotates within the inner cavity of the support platform through the output shaft of the dual-axis motor.

[0011] Furthermore, the threaded sleeves on the front and rear sides are symmetrically distributed on the front and rear sides of the vertical central axis of the bidirectional screw, and through holes are opened at both ends of the upper surface of the support platform. The size of the connecting block is adapted to the size of the inner cavity of the through hole.

[0012] The through holes provided by the above technical solution facilitate the movement of the connecting block and the arc-shaped clamping plate.

[0013] Furthermore, limit rods are fixed to the top of the opposite sides of the connecting blocks at both ends, and limit grooves are opened on the top of the opposite sides of the inner walls of the support platform. The limit rods move back and forth in a straight line within the inner cavity of the limit grooves.

[0014] By adopting the above technical solution, the limiting rod and limiting groove can limit the movement of the connecting block and further limit the movement of the threaded sleeve, so that it can only perform linear movement.

[0015] Furthermore, anti-slip plates are fixed on opposite sides of the front and rear arc-shaped clamping plates, and the anti-slip plates are made of rubber.

[0016] By adopting the above technical solution, the anti-slip plate increases the friction between the arc-shaped clamping plate and the PVC pipe, thereby improving the stability of the PVC pipe fixing.

[0017] Furthermore, the dust collection mechanism includes a support plate, a dust collection box, an exhaust fan, an exhaust pipe, a guide pipe, and a guide hood. The support plate is fixed to the bottom of the left side of the support frame, the dust collection box is fixed to the upper surface of the support plate, the exhaust fan is fixed to the top of the left side of the support frame, one end of the exhaust pipe is connected to the input end of the exhaust fan, one end of the guide pipe is connected to the inner cavity of the dust collection box, the guide hood is fixed to the bottom of the front of the support frame, and the other end of the guide pipe is connected to the inner cavity of the guide hood.

[0018] Using the above technical solution, a lot of dust is generated during the cutting of PVC pipes. The dust can be drawn into the inner cavity of the dust collection box by the dust suction mechanism, which makes it easy for staff to handle it centrally, avoids the large-scale spread of dust and its impact on the working environment, and also prevents staff from inhaling large amounts of dust, thus improving safety during use.

[0019] Furthermore, the other end of the exhaust duct is fixed to the left end of the upper surface of the dust collection box and communicates with the inner cavity of the dust collection box. A dust-blocking mesh plate is inserted into the inner cavity of the exhaust duct.

[0020] By adopting the above technical solution, the dust-blocking mesh plate can prevent dust from entering the inner cavity of the induced draft fan and causing damage to the induced draft fan, thus preventing it from affecting the normal operation of the induced draft fan.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] 1. This PVC pipe cutting equipment, through its positioning mechanism, ensures the fixed position of the PVC pipe during cutting, preventing displacement due to unstable placement. This greatly improves the cutting effect and aesthetics, while also increasing the efficiency of PVC pipe cutting and further enhancing its practicality.

[0023] 2. This PVC pipe cutting equipment generates a lot of dust during the PVC pipe cutting process. The dust collection mechanism can draw the generated dust into the inner cavity of the dust collection box for centralized disposal by the staff, thereby avoiding the large-scale spread of dust and affecting the working environment. At the same time, it can also prevent the staff from inhaling large amounts of dust, thus improving the safety during use. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please see Figure 1 A PVC pipe equipment in this embodiment includes a support platform 1, a support frame 2 fixed in the middle of the upper surface of the support platform 1, a cylinder 3 fixed in the lower surface of the support frame 2, a drive motor 4 fixed in the lower surface of the piston rod of the cylinder 3, a cutting blade 5 fixed in the output shaft of the drive motor 4, a positioning mechanism 6 for positioning PVC pipes in the middle of the inner bottom wall of the support platform 1, and a dust collection mechanism 7 for dust collection at the bottom left side of the support frame 2.

[0031] In this embodiment, the cross-sectional shape of the support frame 2 is an inverted L-shape, and the shape of the support platform 1 is a hollow cuboid.

[0032] It should be noted that when the drive motor 4 is started, the output shaft of the drive motor 4 rotates, which drives the cutting blade 5 to rotate. Then, the cylinder 3 is started, and the piston rod of the cylinder 3 extends, which can push the drive motor 4 downward, thereby adjusting the height of the cutting blade 5, and then cutting the PVC pipe.

[0033] Please see Figures 2 to 3 To position the PVC pipe, the positioning mechanism 6 in this embodiment includes a dual-axis motor 61, two worm gears 62, two bidirectional screws 63, two worm wheels 64, four threaded sleeves 65, four connecting blocks 66, and four arc-shaped clamping plates 67. The dual-axis motor 61 is fixed in the middle of the inner bottom wall of the support platform 1. The two worm gears 62 are respectively fixed to the two output shafts on the left and right sides of the dual-axis motor 61. The two bidirectional screws 63 are respectively rotatably connected to the top of the left and right ends of the opposite side of the front and rear side walls of the inner cavity of the support platform 1 through bearings. The worm wheels 64 are fixed in the middle of the outer surface of the bidirectional screws 63 and are meshed with the worm gears 62. The PVC pipe is placed on the upper surface of the support platform 1, so that the two ends of the PVC pipe are respectively located at the left and right ends of the upper surface of the support platform 1. Then the dual-axis motor 61 is started. The output shaft of the dual-axis motor 61 rotates, which drives the two worm gears 62 to rotate. The rotation of the two worm gears 62 causes the worm wheels 64 meshed with them to rotate.

[0034] The threaded sleeve 65 is threadedly connected to the double-acting screw 63. The connecting block 66 is fixed on the upper surface of the threaded sleeve 65. One end of the connecting block 66 is fixed on the upper surface and extends to the upper side of the support platform 1. The arc-shaped clamping plate 67 is fixed on the upper surface of the connecting block 66. The rotation of the worm gear 64 causes the double-acting screw 63 fixed in its inner cavity to rotate. The rotation of the double-acting screw 63 causes the two threaded sleeves 65 threadedly connected to its surface to move relative to each other. The movement of the two threaded sleeves 65 can drive the two connecting blocks 66 to move relative to each other, thereby causing the two arc-shaped clamping plates 67 at the front and rear to move relative to each other. The relative movement of the two arc-shaped clamping plates 67 at the front and rear can clamp the two sides of the PVC pipe.

[0035] In this embodiment, the two worm gears 62 are rotatably connected to the side opposite to the inner wall of the support platform 1 via bearings. The two bidirectional screws 63 are symmetrically distributed on the left and right sides of the vertical central axis of the support platform 1. The front and rear threaded sleeves 65 are symmetrically distributed on the front and rear sides of the vertical central axis of the bidirectional screws 63. Through holes are opened at both ends of the upper surface of the support platform 1, and the size of the connecting block 66 is adapted to the size of the inner cavity of the through hole.

[0036] It is understandable that the relative movement of the two arc-shaped clamping plates 67 can clamp the two sides of the PVC pipe. By clamping the two ends of the PVC pipe with the arc-shaped clamping plates 67 at both ends, the PVC pipe can be positioned.

[0037] Limiting rods are fixed to the top of the opposite sides of the connecting blocks 66 at both ends. Limiting grooves are opened on the top of the opposite sides of the inner walls of the support platform 1. The limiting rods move back and forth linearly in the inner cavity of the limiting grooves. The limiting rods and limiting grooves can limit the movement of the connecting blocks 66 and further limit the movement of the threaded sleeve 65, so that it can only move in a straight line. Anti-slip plates are fixed on the opposite sides of the arc-shaped clamping plates 67 at both ends. The anti-slip plates are rubber plates. The anti-slip plates increase the friction between the arc-shaped clamping plates 67 and the PVC pipe, and improve the stability of the PVC pipe fixing.

[0038] It should be noted that when cutting PVC pipes, ensuring that the PVC pipes are fixed in position to prevent them from shifting due to instability greatly improves the cutting effect and aesthetics, while also increasing the efficiency of PVC pipe cutting.

[0039] Please see Figure 4 To prevent excessive dust dispersion from affecting the working environment, the dust collection mechanism 7 in this embodiment includes a support plate 71, a dust collection box 72, an exhaust fan 73, an exhaust pipe 74, a guide pipe 75, and a guide hood 76. The support plate 71 is fixed to the bottom left side of the support frame 2, the dust collection box 72 is fixed to the upper surface of the support plate 71, and the exhaust fan 73 is fixed to the top left side of the support frame 2. One end of the exhaust pipe 74 is connected to the input end of the exhaust fan 73. By starting the exhaust fan 73, the exhaust fan 73... The air inlet of 3 generates negative pressure in the inner cavity of the dust collection box 72 through the air duct 74. One end of the air guide pipe 75 is connected to the inner cavity of the dust collection box 72. The air guide hood 76 is fixed to the bottom of the front of the support frame 2. The other end of the air guide pipe 75 is connected to the inner cavity of the air guide hood 76. Thus, the air guide pipe 75 and the inner cavity of the air guide hood 76 generate suction, which can draw the dust during cutting into the inner cavity of the air guide hood 76. Then, under the action of the air guide pipe 75, it enters the inner cavity of the dust collection box 72, and the dust can be collected.

[0040] In this embodiment, the other end of the exhaust pipe 74 is fixed to the left end of the upper surface of the dust collection box 72 and communicates with the inner cavity of the dust collection box 72. A dust-blocking mesh plate is inserted into the inner cavity of the exhaust pipe 74. The dust-blocking mesh plate can prevent dust from entering the inner cavity of the exhaust fan 73 to prevent damage to the exhaust fan 73 and prevent it from affecting the normal operation of the exhaust fan 73.

[0041] Understandably, the dust generated can be drawn into the inner cavity of the dust collection box 72 for collection, which facilitates centralized treatment by staff, avoids the large-scale spread of dust affecting the working environment, and also prevents staff from inhaling large amounts of dust, thus improving safety during use.

[0042] The working principle of the above embodiments is as follows:

[0043] (1) When positioning the PVC pipe, first place the PVC pipe on the upper surface of the support platform 1, so that the two ends of the PVC pipe are located at the left and right ends of the upper surface of the support platform 1 respectively. Then start the dual-axis motor 61. The output shaft of the dual-axis motor 61 rotates, which drives the two worm gears 62 to rotate. The rotation of the two worm gears 62 causes the worm wheel 64 meshing with them to rotate. The rotation of the worm wheel 64 causes the bidirectional screw 63 fixed in its inner cavity to rotate. The rotation of the bidirectional screw 63 causes the two threaded sleeves 65 threadedly connected to its surface to move relative to each other. In turn, the movement of the two threaded sleeves 65 can drive the two threaded sleeves 65 to move relative to each other. The two connecting blocks 66 move relative to each other, causing the two front and rear arc-shaped clamping plates 67 to move relative to each other. The relative movement of the two front and rear arc-shaped clamping plates 67 can clamp the two sides of the PVC pipe. By clamping the two ends of the PVC pipe with the arc-shaped clamping plates 67 at both ends, the PVC pipe can be positioned. Then, the drive motor 4 is started, and the output shaft of the drive motor 4 rotates, driving the cutting blade 5 to rotate. Then, the cylinder 3 is started, and the piston rod of the cylinder 3 extends, which can push the drive motor 4 downward, thereby adjusting the height of the cutting blade 5, and then cutting the PVC pipe.

[0044] (2) A lot of dust will be generated during the cutting of PVC pipes. By starting the blower 73, the air inlet of the blower 73 generates negative pressure in the inner cavity of the dust collection box 72 through the air duct 74. Then, the inner cavity of the air duct 75 and the air hood 76 will generate suction to draw the dust during cutting into the inner cavity of the air hood 76. Then, under the action of the air duct 75, it enters the inner cavity of the dust collection box 72, which can collect the dust. The dust blocking mesh can prevent dust from entering the inner cavity of the blower 73 and prevent the blower 73 from being damaged.
