[0002] Plastic pipe hot-melt connection is a common connection method suitable for various plastic pipe systems, including water supply, drainage, chemical pipelines, etc. This connection method heats the ports of the pipe and the fitting to soften them and contact them at a certain temperature to form a strong connection. When the pipe and fitting ports reach the predetermined temperature, they are quickly joined, and the alignment of the pipe and fitting ports must be ensured. Plastic pipe hot-melt connection is a reliable and economical pipe connection method, which is widely used in construction, industry and municipal engineering. In the prior art, plastic pipe hot-melt connection usually melts the ends of the plastic pipes and then docks them using a docking machine or manually.

[0006] Furthermore, a clamping jacket is fixedly mounted on the clamping block, the clamping jacket is made of rubber material, and is used to clamp the plastic pipe.

[0007] The inner threaded rod drives the active rotating rod to rotate, and the passive rotating rod rotates around the sliding rod, thereby driving the clamping block and the jacket to move outward. At this time, the two jackets are opened, and the plastic pipe can be placed between the two jackets. Subsequently, the screw motor drives the screw bevel gear and the screw to rotate through the motor bevel gear, driving the inner threaded rod to move inward toward the rotating block. Under the action of the column spring rebound, the active rotating rod and the passive rotating rod are driven to rotate, thereby driving the clamping block and the jacket to move inward, and the plastic pipe is clamped by the jacket. Subsequently, the inner threaded rod drives the sliding rod to move inward toward the rotating block through the column spring and the connecting column, thereby driving the two plastic pipes to move toward the rotating block together.

[0010] When the inner threaded rod moves outward, the inner threaded rod pushes the slope block outward, the slide column slides along the slide seat and the swivel seat, the slide column spring is compressed, and the slope block drives the outer swivel rod to rotate, thereby driving the swivel rod and the block to rotate around the swivel seat, so that the block extends out of the outer slide rail to block the sliding rod.

[0011] When the inner threaded rod moves toward the rotating block, under the action of the slope of the slope block, the sliding column spring continuously rebounds, driving the outer rotating rod to rotate, thereby driving the rotating rod and the clamping block to rotate, and the clamping block no longer extends out of the outer slide rail. The clamping block will not prevent the inner threaded rod from moving toward the rotating block. The movement of the inner threaded rod and the sliding rod drives the end of the plastic pipe to contact the heating plate. At this time, the screw motor stops rotating. In the initial state, the heating plate will extend out of the end of the rotating block, and the end of the plastic pipe will be heated and melted by the heating plate.

[0012] Furthermore, the hot melt device includes a rotating block rotatably mounted on a vertical frame, a fixed gear is fixedly mounted on the vertical frame, a rotating motor is fixedly mounted on the rotating block, a motor gear is fixedly mounted on the motor shaft of the rotating motor, an intermediate gear is rotatably mounted in the rotating block, the intermediate gear is meshed with the motor gear, and the intermediate gear is meshed with the fixed gear.

The rotation of the intermediate gear will also drive the center gear and the turntable to rotate, thereby driving the active turntable to rotate, thereby driving 320 to rotate, and the passive turntable drives the sliding plate and the heating plate to slide inward along the rotating block, so that the heating plate shrinks while following the rotation of the rotating block, preventing the heating plate from damaging the melted end of the plastic pipe in the process of following the rotation of the rotating block. After the rotating block rotates ninety degrees, the screw motor continues to rotate to drive the internal threaded rod and the sliding rod to move inward, so that the two plastic pipes with melted ends are butt-connected.

When the sliding rod 108 contacts the block 207, the sliding rod 108 will be blocked by the block 207, and the internal threaded rod 107 continues to move outward and slides along the connecting column 109. The column spring 110 is compressed, and at this time the internal threaded rod 107 drives the active rotating rod 111 to rotate, and the passive rotating rod 112 rotates around the sliding rod 108, thereby driving the clamping block 113 And the jacket 114 moves outward, at this time the two jackets 114 are opened, and the plastic tube 4 can be placed between the two jackets 114, and then the screw motor 102 drives the screw bevel gear 104 and the screw 105 to rotate through the motor bevel gear 103, driving the internal threaded rod 107 to move inward toward the rotating block 302, and under the action of the rebound of the column spring 110, the active rotating rod 111 and the passive rotating rod 112 are driven to rotate, thereby driving the clamping block 113 and the jacket 114 to move inward, and the plastic tube 4 is clamped by the jacket 114, and then the internal threaded rod 107 drives the sliding rod 108 to move inward toward the rotating block 302 through the column spring 110 and the connecting column 109, thereby driving the two plastic tubes 4 to move toward the rotating block 302 together.

[0036] like Fig. 9 , Fig.10 As shown, the locking device includes a swivel seat 208 fixedly mounted on the outer slide rail 106, a slide column 202 is slidably mounted on the slide seat 201 and the swivel seat 208 respectively, a slope block 204 is fixedly mounted on the slide column 202, a slide column spring 203 is arranged between the slope block 204 and the slide seat 201, and a slide column spring 203 is arranged between the slope block 204 and the swivel seat 208, an outer rotating rod 205 is rotatably mounted on the slope block 204, a rotating rod 206 is rotatably mounted on the outer rotating rod 205, a clamping block 207 is fixedly mounted on the rotating rod 206, the clamping block 207 is rotatably mounted on the swivel seat 208, and the slope block 204 is slidably mounted on the internal threaded rod 107.

[0037] like Fig. 9 , Fig.10 As shown, a long groove is provided on the outer slide rail 106 , and the clamping block 207 slides in the long groove of the outer slide rail 106 .

[0038] When the internal threaded rod 107 moves outward, the internal threaded rod 107 pushes the slope block 204 outward, the slide column 202 slides along the slide seat 201 and the rotating seat 208, the slide column spring 203 is compressed, and the slope block 204 drives the outer rotating rod 205 to rotate, thereby driving the rotating rod 206 and the block 207 to rotate around the rotating seat 208, so that the block 207 extends out of the outer slide rail 106 to block the sliding rod 108.

[0039] When the internal threaded rod 107 moves toward the rotating block 302, under the action of the slope of the slope block 204, the sliding column spring 203 continuously rebounds, driving the outer rotating rod 205 to rotate, thereby driving the rotating rod 206 and the block 207 to rotate, and the block 207 no longer extends out of the outer slide rail 106. The block 207 will not prevent the internal threaded rod 107 from moving toward the rotating block 302. The internal threaded rod 107 and the sliding rod 108 move to drive the end of the plastic pipe 4 to contact the heating plate 305. At this time, the screw motor 102 stops rotating. In the initial state, the heating plate 305 will extend out of the end of the rotating block 302, and the end of the plastic pipe 4 will be heated and melted by the heating plate 305.

[0040] like Figure 11-13 As shown, the hot melt device includes a rotating block 302 rotatably mounted on a stand 301, a fixed gear 312 is fixedly mounted on the stand 301, a rotating motor 303 is fixedly mounted on the rotating block 302, a motor gear 304 is fixedly mounted on the motor shaft of the rotating motor 303, an intermediate gear 313 is rotatably mounted in the rotating block 302, the intermediate gear 313 is meshed with the motor gear 304, and the intermediate gear 313 is meshed with the fixed gear 312.

[0041] like Figure 11-13 As shown, a retracting mechanism is provided on the rotating block 302, and the retracting mechanism includes two turntables 308 rotatably installed in the rotating block 302, a central gear 307 is fixedly installed on the turntable 308, the central gear 307 is meshed with the intermediate gear 313, three active turntables 309 are rotatably installed on the turntable 308, an oblique rotating rod 310 is rotatably installed on the active turntable 309, two sliding disks 306 are slidably installed in the rotating block 302, a heating plate 305 is fixedly installed on the sliding disk 306, three passive turntables 311 are rotatably installed on the sliding disk 306, and the passive turntable 311 is rotatably installed with the oblique rotating rod 310.

[0042] After the heating plate 305 heats and melts the end of the plastic tube 4, the rotating motor 303 rotates to drive the motor gear 304 to rotate, thereby driving the intermediate gear 313 to rotate, thereby driving the rotating block 302 to rotate around the stand 301 under the action of the fixed gear 312, and the rotation of the intermediate gear 313 will also drive the central gear 307 and the turntable 308 to rotate, thereby driving the active turntable 309 to rotate, thereby driving 320 to rotate, and driving the sliding plate 306 and the heating plate 305 to slide inward along the rotating block 302 through the passive turntable 311, so that the heating plate 305 shrinks while following the rotation of the rotating block 302, preventing the heating plate 305 from damaging the melted end of the plastic tube 4 during the process of following the rotation of the rotating block 302, and when the rotating block 302 rotates ninety degrees, the screw motor 102 continues to rotate to drive the internal threaded rod 107 and the sliding rod 108 to move inward, so that the two ends of the plastic tubes 4 that have been melted are connected.

[0043] The working principle of a plastic pipe butt hot-melt connection device disclosed in the present invention is as follows: in the initial state, the column spring 110 is in an unstressed state, the screw motor 102 rotates to drive the motor bevel gear 103 to rotate, thereby driving the screw bevel gear 104 and the screw 105 to rotate, and driving the two internal threaded rods 107 to move outward at the same time. When the internal threaded rod 107 moves outward, the internal threaded rod 107 pushes the slope block 204 outward, the sliding column 202 slides along the sliding seat 201 and the rotating seat 208, the sliding column spring 203 is compressed, and the slope block 204 drives the outer rotating rod 205 to rotate, thereby driving the rotating rod 206 and the block 207 to rotate around the rotating seat 208, so that the block 207 extends out of the outer slide rail 106 to block the sliding rod 108. The internal threaded rod 107 drives the sliding rod 108 to slide outward along the outer slide rail 106 through the connecting column 109 and the column spring 110. When the sliding rod 108 contacts the block 207, the sliding rod 108 will be blocked by the block 207, and the internal threaded rod 107 continues to move outward and slides along the connecting column 109. The column spring 110 is compressed. At this time, the internal threaded rod 107 drives the active rotating rod 111 to rotate, and the passive rotating rod 112 rotates around the sliding rod 108, thereby driving the clamping block 113 and the jacket 114 to move outward. At this time, the two jackets 114 are opened, and the plastic pipe 4 can be placed between the two jackets 114. Then, the screw motor 102 drives the screw bevel gear 104 and the screw 105 to rotate through the motor bevel gear 103, driving the internal threaded rod 107 to move inward toward the rotating block 302, and under the action of the rebound of the column spring 110, the active rotating rod 111 and the passive rotating rod 112 are driven to rotate, thereby driving the clamping block 113 and the sleeve 114 to move inward, and the plastic pipe 4 is clamped by the sleeve 114, and then the internal threaded rod 107 drives the sliding rod 108 to move inward toward the rotating block 302 through the column spring 110 and the connecting column 109, thereby driving the two plastic pipes 4 to move together toward the rotating block 302. When the internal threaded rod 107 moves toward the rotating block 302, under the action of the slope of the slope block 204, the sliding column spring 203 continuously rebounds, driving the outer rotating rod 205 to rotate, thereby driving the rotating rod 206 and the block 207 to rotate, and the block 207 no longer extends out of the outer slide rail 106. The block 207 will not prevent the internal threaded rod 107 from moving toward the rotating block 302. The internal threaded rod 107 and the sliding rod 108 move to drive the end of the plastic pipe 4 to contact the heating plate 305. At this time, the screw motor 102 stops rotating. In the initial state, the heating plate 305 will extend out of the end of the rotating block 302, and the end of the plastic pipe 4 will be heated and melted by the heating plate 305.After the heating plate 305 heats and melts the end of the plastic tube 4, the rotating motor 303 rotates to drive the motor gear 304 to rotate, thereby driving the intermediate gear 313 to rotate, thereby driving the rotating block 302 to rotate around the stand 301 under the action of the fixed gear 312, and the rotation of the intermediate gear 313 will also drive the central gear 307 and the turntable 308 to rotate, thereby driving the active turntable 309 to rotate, thereby driving 320 to rotate, and driving the sliding plate 306 and the heating plate 305 to slide inward along the rotating block 302 through the passive turntable 311, so that the heating plate 305 shrinks while following the rotation of the rotating block 302, preventing the heating plate 305 from damaging the melted end of the plastic tube 4 during the process of following the rotation of the rotating block 302, and when the rotating block 302 rotates ninety degrees, the screw motor 102 continues to rotate to drive the internal threaded rod 107 and the sliding rod 108 to move inward, so that the two ends of the plastic tubes 4 that have been melted are connected.
