Description

Technical Field

[0001] The present invention relates to the field of butt joint processing of plastic pipes, and specifically to a hot melt butt joint processing device for plastic pipes. Background Art

[0002] In modern industrial and construction fields, plastic pipes are increasingly widely used. Plastic pipes have many advantages such as corrosion resistance, light weight, and convenient installation, and are widely used in multiple fields such as water supply and drainage, gas transmission, and chemical industry.

[0003] However, in the process of laying and connecting plastic pipes, traditional connection methods often have some problems. On the one hand, for the hot melt butt joint processing of plastic pipes, when traditional equipment clamps the pipes, it usually uses fixtures with fixed sizes, which are difficult to adapt to plastic pipes with different diameters, resulting in limited application ranges. When facing the connection requirements of pipes with multiple specifications, it is necessary to frequently replace the fixtures, which not only increases the cost but also reduces the work efficiency.

[0004] On the other hand, in the butt joint process of traditional hot melt butt joint equipment, it is difficult to ensure the uniformity of the butt joint combination force. Since plastic pipes need a certain pressure for butt joint in the hot melt state, but traditional equipment often cannot accurately control this pressure, and it is easy to have uneven stress at the butt joint. This may lead to insecure pipe interfaces, and leakage, rupture and other problems are likely to occur during subsequent use, affecting the stability and safety of the pipe system.

[0005] In addition, when hot melt butt jointing plastic pipes of different materials, the required butt joint forces are also different. Traditional equipment usually cannot flexibly adjust the butt joint force according to the differences in pipe materials, and it is difficult to meet the butt joint requirements of plastic pipes of various materials.

[0006] In summary, in order to solve these problems existing in traditional plastic pipe hot melt butt joint processing equipment, improve the butt joint quality, expand the application range, and enhance the versatility and adaptability of the equipment, it is of great practical significance to develop a new type of plastic pipe hot melt butt joint processing device.

[0011] Preferably, at the bottom end of the housing is fixedly installed a double-acting cylinder, on the outer diameters of the fiberglass elastic sheets are movably installed support rings, and the driving ends of the double-acting cylinders are all fixedly connected to the bottom ends of the corresponding support rings.

[0012] Preferably, in the middle of the top end of the housing is fixedly installed a DC motor, the driving end of the DC motor extends above the workbench and is fixedly connected with a turntable, on both sides of the upper surface of the turntable are movably connected with connecting rods, the ends of the connecting rods are all movably connected with abutting blocks, the outer side ends of the abutting blocks all abut against the inner sides of the corresponding movable seats and the bottoms of the abutting blocks are all movably arranged on the upper surfaces of the guide rails.

[0013] Preferably, inside the annular grooves are movably installed internal gear rings, on one side of each clamping plate is fixedly connected with a rack plate, inside the annular grooves near one side of the L-shaped sliding blocks are movably installed long gears, the lower parts of the long gears are all meshed with the inner walls of the internal gear rings, and the upper parts of the long gears are all meshed with the outer sides of the corresponding L-shaped sliding grooves.

[0014] Preferably, one side of the inner end of the fixing ring is movably installed at both ends of the rotating shaft, both ends of the rotating shaft are fixedly connected to the inner side of one of the long gears, the other side of the inner end of the fixing ring is fixedly installed with a reduction motor through a mounting plate, a worm is fixedly installed at the driving end of the reduction motor, a worm gear is fixedly connected to the outer diameter of the rotating shaft, and the worm gear is meshed with the inner end of the worm.

[0015] Preferably, the bottom of the inner end of the fixing ring is fixedly connected to both ends of the connecting seat, and the bottom ends of the connecting seat are respectively fixedly installed on the tops of the corresponding movable seats.

[0016] Working principle: First, use a DC motor to drive the turntable to rotate slightly by a certain angle. The rotating turntable will drive the connecting rods on both sides to push the abutting blocks outwards, causing the abutting blocks to push the movable seats outwards, moving the two movable seats slightly away from each other by a certain distance. Subsequently, the two plastic pipes to be processed by hot melt butt joint are respectively inserted into the through holes in the two pipe clamping mechanisms, and the inner ends of the pipes are mutually aligned and fitted. Then, start the reduction motor, drive the worm to rotate through the reduction motor. The rotating worm meshes with the worm wheel to drive the worm wheel and the rotating shaft to rotate. The rotating shaft will drive the long gears at both ends to rotate. When the long gears rotate, they will drive the internal gear ring inside the annular groove to rotate. When the internal gear ring rotates, it will drive all the long gears to rotate. When all the long gears rotate, they will mesh with the rack plates on one side of all the L-shaped sliders, thereby driving all the L-shaped sliders to slide in the L-shaped chutes, causing all the clamping plates to move inwards simultaneously to complete the clamping work of the plastic pipes. Using multiple movable clamping plates to clamp the pipes can make the device adapt to plastic pipes of various different diameters and improve the applicable range. Subsequently, use the DC motor to drive the turntable to rotate by a certain angle again. The rotating turntable will drive the connecting rods on both sides to push the abutting blocks outwards, causing the abutting blocks to push the movable seats outwards and move the two movable seats away from each other by a certain distance. After completion, start the hydraulic cylinder. The hydraulic cylinder pushes the electric heating plate down to the middle position between the two pipes, turns on the electric heating plate, and heats the port surfaces of the two pipes until the ports become in a molten state. Subsequently, the hydraulic cylinder controls the electric heating plate to rise and reset. The DC motor controls the turntable to rotate in the reverse direction, and uses the pushing rod to drive the abutting blocks to quickly retract inwards, so that the abutting blocks release the abutting and blocking effect on the movable seats. During the process of the movable seats being pushed outwards before, they will push the vertical plate outwards through the pushing rod and cause the rotating seat to rotate. The rotating plate will bend the fiberglass elastic sheet through the internal roller. When the fiberglass elastic sheet is bent, it will accumulate elastic potential energy. At the same time, during the bending process of the rotating seat and the fiberglass elastic sheet, the lever arm of the bent fiberglass elastic sheet is also increasing, thereby compensating for the continuously increasing elastic force of the fiberglass elastic sheet as the bending degree increases. Similarly, when the fiberglass elastic sheet releases the elastic force and returns to the normal position, it will drive the rotating seat to return to the normal position. During the process of the fiberglass elastic sheet returning to the normal position, the lever arm will continuously decrease, compensating for the continuously decreasing elastic force of the fiberglass elastic sheet as the bending degree decreases. Thus, the force applied by the rotating seat to the pushing rod through the vertical plate remains uniform throughout the process. When the abutting blocks release the abutting and blocking effect on the movable seats, use the pushing effect of the pushing rod to drive the two pipe clamping structures to move inwards simultaneously, and complete the butt joint of the pipe interfaces in the molten state. Using the force applied by the rotating seat to the pushing rod through the vertical plate to remain uniform throughout the process, when the two pipe interfaces are butted in the molten state, they always maintain a uniform butt joint force, which can improve the butt joint quality and the finished product quality. In addition, the position of the two support rings can be changed by controlling the two-way cylinder, thereby changing the support point positions of the two fiberglass elastic sheets. When the support point positions change,When rotating by the same angle, the elastic force generated will also change accordingly, thus facilitating the adaptation to the different magnitudes of force required for the butt joint of plastic pipes made of different materials.

[0017] The present invention provides a hot melt butt joint processing device for plastic pipes. It has the following beneficial effects: 1. In the present invention, the reduction motor drives the worm to rotate, which meshes with the worm gear and drives the rotation of the rotating shaft and the long gear. Then, the internal gear ring drives all the long gears to rotate, and meshes with the rack plate to drive all the clamping plates to move inward simultaneously, clamping the plastic pipe. This way of clamping with multiple movable clamping plates enables the device to adapt to plastic pipes of various different diameters, improving the scope of application.

[0018] 2. When the glass fiber elastic piece is bent and restored in the present invention, its force arm will change with the change of the bending degree, thereby compensating for the continuously changing elastic force of the glass fiber elastic piece with the change of the bending degree, and enabling the force exerted by the rotating seat on the push-pull rod through the vertical plate to remain uniform throughout the process. When the two pipe interfaces are butted in a molten state, a uniform butt joint force is always maintained, which can improve the butt joint quality and the finished product quality.

[0019] 3. In the present invention, the position of the two support rings can be changed by controlling the two-way cylinder, thereby changing the support point position of the two glass fiber elastic pieces. After the support point position changes, the elastic force generated when rotating by the same angle will also change accordingly, thus facilitating the adaptation to the different magnitudes of force required for the butt joint of plastic pipes made of different materials.

[0020] 4. The present invention uses a DC motor to drive the turntable to rotate, and the movable seat is pushed to move through the connecting rod and the abutting block, realizing the position adjustment during the clamping and butt joint of the pipe, with convenient operation. At the same time, the hydraulic cylinder controls the lifting of the electric heating plate to heat the pipe port, and the whole process has a high degree of automation, reducing the labor intensity of manual operation and improving the work efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example: Please see attached Figure 1 -Attached Figure 2 The embodiment of the present invention provides a plastic pipe hot-melt butt processing device, such as Figure 1 As shown, the workbench 1 includes a workbench 1, which serves as the basic support platform of the entire device and provides a stable environment for the installation and operation of various components. Two guide rails 2 are fixedly installed on the upper surface of the workbench 1. The guide rails 2 play a role in guiding and supporting the movement of the movable seat 3 to ensure that the movable seat 3 maintains a stable direction and trajectory during the movement. The movable seats 3 are movably installed on both sides of the guide rails 2. The movable seats 3 can slide smoothly on the guide rails 2 to provide support and movement functions for the pipe clamping mechanism 4. The upper surface of the movable seat 3 is provided with a pipe clamping mechanism 4. The pipe clamping mechanism 4 is used to clamp the plastic pipe to be hot-melt butt-jointed to ensure that the pipe is in the process of processing. Maintaining a stable position, the bottom end of the workbench 1 is fixedly connected with a shell 5, which provides protection and installation space for various internal components. A gantry 18 is fixedly connected to the middle of the top of the workbench 1, and the gantry 18 provides a stable installation position for the hydraulic cylinder 19 and the electric heating plate 20. The top of the gantry 18 is fixedly installed with a hydraulic cylinder 19, which has a strong driving force and can accurately control the lifting of the electric heating plate 20. The driving end of the hydraulic cylinder 19 passes through the top of the gantry 18 and is fixedly installed with the electric heating plate 20. The electric heating plate 20 is used to heat the port surface of the plastic pipe to make it molten for docking processing.

[0025] In this embodiment, the pipe clamping mechanism 4 includes two fixing rings 401. Through holes 402 are respectively formed in the middle parts of the inner sides of the fixing rings 401. The through holes 402 are channels for inserting plastic pipes. Annular grooves 403 are formed between the outer walls of the fixing rings 401 and the through holes 402. The annular grooves 403 provide installation spaces for various internal components. A number of L-shaped sliding grooves 405 are respectively formed at the outer ends of the workbench 1. L-shaped sliding blocks 406 are movably arranged inside the L-shaped sliding grooves 405. The L-shaped sliding blocks 406 can slide in the L-shaped sliding grooves 405 to realize the clamping and loosening actions of the pipes. The inner ends of the L-shaped sliding blocks 406 extend into the corresponding through holes 402 and are fixedly connected with clamping plates 407. The clamping plates 407 are used to directly contact and clamp the plastic pipes.

[0026] Further, internal gear rings 404 are movably installed inside the annular grooves 403. The internal gear rings 404 rotate driven by the long gears 409 to realize the synchronous movement of multiple long gears 409. Rack plates 408 are fixedly connected to one sides of the clamping plates 407. The rack plates 408 are meshed and driven with the long gears 409 to realize the movement of the clamping plates 407. Long gears 409 are movably installed on one sides of the annular grooves 403 close to the L-shaped sliding blocks 406. The long gears 409 rotate driven by the rotating shafts 410 and are meshed and driven with the internal gear rings 404 and the rack plates 408. The lower parts of the long gears 409 are meshed and connected with the inner walls of the internal gear rings 404. The upper parts of the long gears 409 are meshed and connected with the outer sides of the corresponding L-shaped sliding grooves 405.

[0027] Further, one sides of the inner ends of the fixing rings 401 are respectively movably installed at both ends of the rotating shaft 410. The rotating shaft 410 provides a rotation axis for the long gears 409. Both ends of the rotating shaft 410 are fixedly connected to the inner sides of one of the long gears 409. On the other sides of the inner ends of the fixing rings 401, a reduction motor 411 is fixedly installed through a mounting plate. The reduction motor 411 provides precise rotational power for driving the worm 412 to rotate. A worm 412 is fixedly installed at the driving end of the reduction motor 411. The worm 412 is meshed and driven with the worm gear 413 to drive the rotating shaft 410 to rotate. A worm gear 413 is fixedly connected to the outer diameter of the rotating shaft 410 and is meshed and connected with the inner side end of the worm 412.

[0028] Further, the bottom parts of the inner ends of the fixing rings 401 are respectively fixedly connected to both ends of the connecting seat 414. The connecting seat 414 provides stable support for the fixing rings 401. The bottom ends of the connecting seat 414 are respectively fixedly installed on the tops of the corresponding movable seats 3.

[0029] Specifically, first, the DC motor 14 is used to drive the turntable 15 to slightly rotate a certain angle. The rotating turntable 15 will drive the connecting rods 16 on both sides to push the abutting blocks 17 outward, so that the abutting blocks 17 push the movable seats 3 outward, moving the two movable seats 3 slightly away from each other for a certain distance to leave space for inserting the plastic pipes later. Subsequently, the two plastic pipes to be hot-melt butt-jointed are respectively inserted into the through holes 402 in the two pipe clamping mechanisms 4, and the inner ends of the pipes are mutually abutted and aligned to ensure the accuracy of the butt-joint. Then, the reduction motor 411 is started, and the worm 412 is driven to rotate by the reduction motor 411. The rotating worm 412 meshes with the worm gear 413 to drive the worm gear 413 and the rotating shaft 410 to rotate. The rotating shaft 410 will drive the long gears 409 at both ends to rotate. When the long gears 409 rotate, they will drive the internal gear ring 404 in the annular groove 403 to rotate. When the internal gear ring 404 rotates, it will drive all the long gears 409 to rotate. When all the long gears 409 rotate, they will mesh with the rack plates 408 on one side of all the L-shaped sliders 406, thereby driving all the L-shaped sliders 406 to slide in the L-shaped chutes 405, so that all the clamping plates 407 move inward simultaneously to realize the clamping of the plastic pipes. Using multiple movable clamping plates 407 to clamp the pipes can make the device adapt to plastic pipes of various different diameters and improve the scope of application.

[0030] Furthermore, installation grooves 6 are respectively formed on both sides inside the housing 5. The installation grooves 6 provide space for the installation of the fiberglass elastic sheets 8. Both ends of the housing 5 are movably connected with rotating seats 7. The rotating seats 7 can rotate at both ends of the housing 5 to provide support for the vertical plates 12 and the pressing rollers 9. Vertical plates 12 are fixedly connected to the tops of the rotating seats 7. The vertical plates 12 are used to connect the push-pull rods 13 to transmit the force of the rotating seats 7. Push-pull rods 13 are movably installed on the upper sides of the outer ends of the movable seats 3. The push-pull rods 13 play a role in connecting the movable seats 3 and the vertical plates 12 and transmitting force during the operation of the device. The ends of the push-pull rods 13 are movably connected to the tops of the corresponding vertical plates 12.

[0031] Furthermore, fiberglass elastic sheets 8 are fixedly connected inside the installation grooves 6, and the ends of the fiberglass elastic sheets 8 all extend into the interiors of the corresponding rotating seats 7. The fiberglass elastic sheets 8 have good elasticity and store and release elastic potential energy during the operation of the device. Pressing rollers 9 are fixedly connected to the upper sides inside the rotating seats 7, and the bottoms of the pressing rollers 9 all abut against the upper surfaces of the corresponding fiberglass elastic sheets 8. When the rotating seats 7 rotate, the pressing rollers 9 bend the fiberglass elastic sheets 8 to make the fiberglass elastic sheets 8 store elastic potential energy.

[0032] Furthermore, a two-way cylinder 10 is fixedly installed at the bottom end of the housing 5. The two-way cylinder 10 can precisely control the position of the support ring 11. Support rings 11 are movably installed on the outer diameter of the fiberglass elastic sheet 8. The support rings 11 are used to change the position of the support points of the fiberglass elastic sheet 8. The driving ends of the two-way cylinder 10 are fixedly connected to the bottom ends of the corresponding side support rings 11.

[0033] Furthermore, a DC motor 14 is fixedly installed in the middle of the top end of the housing 5. The DC motor 14 provides precise rotational power for controlling the rotation of the turntable 15. The driving end of the DC motor 14 extends above the workbench 1 and is fixedly connected to a turntable 15. The turntable 15 rotates under the drive of the DC motor 14, driving the connecting rod 16 to move. Both sides of the upper surface of the turntable 15 are movably connected to a connecting rod 16. The connecting rod 16 is used to connect the turntable 15 and the abutting block 17 to transmit force. The ends of the connecting rod 16 are movably connected to an abutting block 17. The abutting block 17 is used to abut against the movable seat 3 to control the position of the movable seat 3. The outer ends of the abutting block 17 abut against the inner sides of the corresponding side movable seats 3, and the bottoms of the abutting block 17 are movably arranged on the upper surface of the guide rail 2.

[0034] Specifically, the DC motor 14 is used to drive the turntable 15 to rotate a certain angle again. The rotating turntable 15 will drive the connecting rods 16 on both sides to push the abutting block 17 outwards, causing the abutting block 17 to push the movable seat 3 outwards, pushing the two movable seats 3 outwards and away from each other by a certain distance, leaving space for the descent of the electric heating plate 20. After completion, the hydraulic cylinder 19 is started. The hydraulic cylinder 19 pushes the electric heating plate 20 down to the middle position between the two pipes, turns on the electric heating plate 20, heats the port surfaces of the two pipes until the ports become in a molten state. Subsequently, the hydraulic cylinder 19 controls the electric heating plate 20 to rise and reset. The DC motor 14 controls the turntable 15 to rotate in the reverse direction, and drives the abutting block 17 to quickly retract inwards by the action of the push rod 13, so that the abutting block 17 releases the abutting and blocking effect on the movable seat 3. During the process of the movable seat 3 being pushed outwards before, it will push the vertical plate 12 outwards through the push rod 13 and cause the rotating seat 7 to rotate. The rotating rotating plate 7 will press and bend the fiberglass elastic sheet 8 through the internal pressure roller 9. When the fiberglass elastic sheet 8 is bent, elastic potential energy will be accumulated. At the same time, during the bending process of the rotating seat 7 and the fiberglass elastic sheet 8, the force arm of the bent fiberglass elastic sheet 8 is also increasing, thereby compensating for the continuously increasing elastic force of the fiberglass elastic sheet 8 as the bending degree increases. Similarly, when the fiberglass elastic sheet 8 releases the elastic force and returns to the normal position, it will drive the rotating seat 7 to return to the normal position. During the process of the fiberglass elastic sheet 8 returning to the normal position, the force arm will continuously decrease, compensating for the continuously decreasing elastic force of the fiberglass elastic sheet 8 as the bending degree decreases, so that the force applied by the rotating seat 7 to the push rod 13 through the vertical plate 12 remains uniform throughout the process.

[0035] When the resistance block 17 releases the resistance and blocking effect on the movable seat 3, the pushing effect of the push-pull rod 13 is utilized to drive the two pipe clamping structures 4 to move inward at the same time, and the pipe interfaces in the molten state are connected. The force applied to the push-pull rod 13 by the rotating seat 7 through the vertical plate 12 is kept uniform throughout the whole process, so that when the two pipe interfaces are connected in the molten state, a uniform connection force is always maintained, which can improve the connection quality and the quality of the finished product.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
