DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0038] The cooling mechanism 5 includes a cooling chamber 51, the bottom end of the cooling chamber 51 is fixedly connected to the top end of the box body 1, a conveying pipe is connected to the outer wall of one side of the cooling chamber 51, and the end of the conveying pipe is connected to the thermoplastic extruder body 3, a plurality of spiral grooves 52 of semi-arc structure are opened in the inner wall of the cooling chamber 51, and the plurality of spiral grooves 52 are arranged end to end, a reciprocating screw 53 is rotatably connected to the inner wall of the cooling chamber 51, and a positioning sleeve 54 is threadedly connected to the outer wall of the reciprocating screw 53, a rotating sleeve 55 is rotatably connected to the inner wall of the positioning sleeve 54, a guide block 56 is fixedly connected to the outer wall of the rotating sleeve 55, and the outer diameter of the guide block 56 matches the inner diameter of the spiral groove 52, and a plurality of groups of water outlet parts 57 are arranged in a medium-spaced annular array on the inner wall of the rotating sleeve 55, and the plurality of groups of water outlet parts 57 are composed of a plurality of water outlet parts 57;

[0039] In this embodiment, Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the water outlet member 57 includes a water outlet pipe 571, the outer wall of the water outlet pipe 571 is fixedly connected to the rotating ring, a driving gear 572 is fixedly connected to the outer wall of the water outlet pipe 571, a water outlet is opened in the bottom wall of the water outlet pipe 571, the bottom end of the driving gear 572 is fixedly connected to a synchronous ring 573 through a metal rod, a connecting plate 574 is fixedly connected to the inner wall of the synchronous ring 573, a threaded rod 575 is fixedly connected to the center of the connecting plate 574, the top of the threaded rod 575 is threadedly connected to an impact block 576, an extension plate 577 is fixedly connected to the side wall of the impact block 576, and both ends of the extension plate 577 are slidably connected to the inner wall of the water outlet pipe 571, and the release sleeve 59 is gradually released. The release sleeve 59 drives the push plate 510 to move backward synchronously. At this time, since the tooth block 5102 on the push plate 510 is set with a half shaft, when the tooth block 5102 moves forward, the tooth block 5102 no longer rotates, and can drive the driving gear 572 to rotate. The driving gear 572 rotates, and synchronously drives the synchronization ring 573 below to rotate. The threaded rod 575 on the synchronization ring 573 also rotates synchronously. Due to the threaded connection setting, the rotation of the threaded rod 575 can push the impact block 576 to move upward, and the impact block 576 gradually enters the water outlet, so that the water flow becomes a high-speed impact water flow. At this time, because it is far away from the output pipe, the water flow impacts the cooled part and does not impact the soft part.

[0040] In this embodiment, Figure 7 As shown, the driving gears 572 on the plurality of water outlets 57 are connected together by a gear belt, and the plurality of water outlets 57 are arranged at the same level. Through the combination of the plurality of water outlets 57, the pipeline can be flushed at multiple angles to increase the cooling and scrubbing effects;

[0041] In this embodiment, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cooling mechanism 5 further includes a movable sleeve 58, the outer wall of the movable sleeve 58 is fixedly connected to the inner wall of the rotating sleeve 55, and the movable sleeve 58 is symmetrically arranged in two groups about the axis of the rotating sleeve 55. A release sleeve 59 is slidably connected in the inner wall of the movable sleeve 58, and a damping structure is adopted between the release sleeve 59 and the movable sleeve 58, and a reset spring is fixedly connected to the front end of the release sleeve 59, and the front end of the reset spring is fixedly connected to the inner wall of the movable sleeve 58, and a push plate 510 is fixedly connected to the front end of the release sleeve 59, and the push plate 510 extends to the front end of the driving gear 572;

[0042] An active cavity 511 is provided in the inner wall of the active sleeve 58, a brush plate 512 is vertically slidably connected to the inner wall of the active cavity 511, and a plurality of bristles are fixedly provided at the bottom end of the brush plate 512, and a pressure rod 513 is fixedly provided at the top end of the brush plate 512;

[0043] A deep groove 514 is formed in the inner wall of the release sleeve 59, and the deep groove 514 is arranged at the same level as the pressure rod 513. As the release sleeve 59 is gradually reset, the pressure rod 513 on the brush plate 512 moves out of the deep groove 514, and is pressed by the inner wall of the release sleeve 59, pressing the brush plate 512 downward, so that the bristles of the brush plate 512 contact the surface of the pipe fitting, and the water flow can be used for brushing while cooling;

[0044] In this embodiment, Figure 6 As shown, the push plate 510 includes a cavity 5101, which is opened on the side wall of the push plate 510, and a plurality of cavities 5101 are opened horizontally at equal intervals, and a gear block 5102 is rotatably connected to the inner walls of the plurality of cavities 5101 through a torsion spring, and the shaft ends of the plurality of gear blocks 5102 are semi-axial structures, and the plurality of gear blocks 5102 are meshed with the driving gear 572. Since the gear block 5102 on the push plate 510 is semi-axially arranged, when the gear block 5102 moves forward, the gear block 5102 no longer rotates, and can drive the driving gear 572 to rotate;

[0045] In this embodiment, Figure 6 and Figure 7 As shown, the two sets of release sleeves 59 are arranged opposite to each other, and the push plates 510 at the front ends of the two sets of release sleeves 59 are arranged symmetrically about the vertical axis of the rotating sleeve 55. Through the arrangement of the release sleeves 59 and the push plates 510 arranged opposite to each other, the brush plates 512 and the water flow can be controlled at both ends;

[0046] In this embodiment, Figure 2 , Fig. 9 , Fig.10 and Fig.11 As shown, the power mechanism 6 includes a power bin 61, the bottom end of the power bin 61 is fixedly connected to the top end of the box body 1, a motor is fixedly connected to the inner wall of the power bin 61, and pinions 62 are meshed on both side walls of the front end of the main shaft of the motor, an outer ring 63 is meshed on the outer wall of the pinion 62, and a movable bin 64 is rotatably connected to the front end of the outer ring 63;

[0047] The front end of the outer ring 63 is fixedly connected to a driving rod 65, and the driving rod 65 is set as a threaded structure. A movable sleeve 66 is threadedly connected to the outer wall of the driving rod 65, and a pressure ring 67 is fixedly connected to the front end of the movable sleeve 66. A pull plate 68 is fixedly connected to the top of the movable sleeve 66. The outer wall of the bottom end of the pull plate 68 is slidably connected to the top wall of the movable bin 64. The motor drives the two pinions 62 to rotate and drive the outer ring 63 to rotate. At this time, the outer ring 63 rotates slowly, pushing the driving rod 65 to rotate. The rotation of the driving rod 65 can be set through the threaded structure to drive the movable sleeve 66 to move horizontally forward on the driving rod 65. At the same time, the driving rod 65 will drive the pressure ring 67 at the front end to move synchronously to extend the power release.

[0048] In this embodiment, Fig.10 and Fig.11 As shown, the power mechanism 6 also includes an inner rod 69, the outer wall of the inner rod 69 is plug-connected with the inner wall of the driving rod 65, the inner rod 69 and the driving rod 65 are connected by a spline structure, the bottom end of the inner rod 69 and the rear wall of the driving rod 65 are connected by a telescopic spring, a round block 610 is fixedly connected to the outer wall of the inner rod 69, a connector 611 is fixedly connected to the front end of the inner rod 69, the inner diameter of the round block 610 matches the outer diameter of the connector 611, and a limiting groove 612 is provided at the top of the inner rod 69;

[0049] A lever 613 is rotatably connected to the inner wall of the connector 611 through a torsion spring, the left bottom end of the lever 613 is fixedly connected to a limit block 614, and the other end of the lever 613 extends to the outer surface of the connector 611, and the outer diameter of the connector 611 matches the inner diameter of the pressure ring 67;

[0050] The front end of the connector 611 is arranged horizontally with the reciprocating screw rod 53, and the axial end of the reciprocating screw rod 53 is fixedly connected with a connector 611 of the same structure, and the two connectors 611 are arranged relatively staggered. As the pressing ring 67 continues to move forward, the pressing ring 67 will gradually fit with the outer wall of the connector 611 so that the connector 611 is completely inserted into the pressing ring 67. At this time, the inner side wall of the pressing ring 67 contacts the top of the lever 613 on the outer wall of the connector 611, squeezing one end of the lever 613 to rotate downward, and at this time the other end of the lever 613 The end rises, and the limit block 614 on the lever 613 moves up synchronously, removing the limit block 614 from the limit groove 612 on the inner rod 69. At this time, the inner rod 69 is in an unlocked state, and the internal return spring force is released to push the inner rod 69 out of the driving rod 65. Since the inner rod 69 is connected to the connecting head 611, the removal of the inner rod 69 can push the connecting head 611 to move forward quickly and dock with the connecting head 611 in front, so that the power of the motor is released with a delay. At this time, the power of the motor is docked with the reciprocating screw rod 53.

[0051] The use method and advantages of the present invention: The working process of the thermoplastic tube extrusion device is as follows:

[0052] like Figures 1 to 11 As shown, along with the start-up of the device, the thermoplastic extruder body 3 starts to work, and continuously extrude the externally supplied materials. At the same time, the motor drives the two pinions 62 to rotate and drive the outer ring 63 to rotate. At this time, the outer ring 63 rotates slowly, pushing the driving rod 65 to rotate. The rotation of the driving rod 65 can be set by a threaded structure, driving the movable sleeve 66 to move horizontally forward on the driving rod 65, and at the same time, the driving rod 65 will drive the front end pressure ring 67 to move synchronously;

[0053] Then, as the pressure ring 67 continues to move forward, the pressure ring 67 will gradually fit with the outer wall of the connector 611 and make the connector 611 completely inserted into the pressure ring 67. At this time, the inner side wall of the pressure ring 67 contacts the top of the lever 613 on the outer wall of the connector 611, squeezing one end of the lever 613 to rotate downward. At this time, the other end of the lever 613 rises, and the limit block 614 on the lever 613 moves upward synchronously to move the limit block 614 out of the limit groove 612 on the inner rod 69. At this time, the inner rod 69 is in an unlocked state, and the internal return spring elastic force is released to push the inner rod 69 out of the driving rod 65. Since the inner rod 69 is connected to the connector 611, the removal of the inner rod 69 can push the connector 611 to move forward quickly and dock with the connector 611 in front, so that the power of the motor is delayed and released. At this time, the power of the motor is docked with the reciprocating screw rod 53.

[0054] Then, the reciprocating screw rod 53 rotates, and the rotating sleeve 55 starts to slide horizontally in the cooling chamber 51. At this time, since a plurality of semi-arc-shaped spiral grooves 52 are provided in the inner wall of the cooling chamber 51, and the plurality of spiral grooves 52 are arranged end to end, the rotating sleeve 55 moves forward. A guide block 56 is provided on the outer surface of the rotating sleeve 55, so that the rotating sleeve 55 continuously swings back and forth under the guidance of the guide block 56 during the forward movement, and simultaneously drives a plurality of water spraying parts in the inner wall of the rotating sleeve 55 to swing back and forth, thereby increasing the water spraying angle and the cooling effect.

[0055] At the same time, when the rotating sleeve 55 is in the initial state, the rotating sleeve 55 is located at the position closest to the output pipe, and the release sleeve 59 on the rotating sleeve 55 is squeezed by the side wall of the cooling chamber 51 and is integrally received in the movable sleeve 58. At this time, the release sleeve 59 moves forward toward the inner wall of the movable sleeve 58. Since the inner wall of the release sleeve 59 is provided with a deep groove 514, the deep groove 514 will quickly move to the top of the brush plate 512. Through the device of the pressure rod 513 at the top of the brush plate 512, the brush plate 512 is quickly reset and received in the movable sleeve 58 by the spring, so as to avoid the brush plate 512 from rubbing against the outer wall of the pipe just out, causing damage to the finished product;

[0056] When the release sleeve 59 is received in the movable sleeve 58, the front end of the release sleeve 59 pushes the push plate 510 to move forward. Since the tooth block 5102 inside the push plate 510 has a bevel formed by machining, the push plate 510 moves forward and the tooth block 5102 contacts the tooth edge of the driving gear 572, causing the tooth block 5102 to rotate through the shaft end. At this time, the push plate 510 cannot drive the driving gear 572 to change the water flow.

[0057] When the rotating sleeve 55 starts to move, due to the damping structure between the release sleeve 59 and the movable sleeve 58, the release sleeve 59 cannot be released instantly, but can only be released slowly along with the gradual movement of the rotating sleeve 55. During the slow release process, the rotating sleeve 55 will pass through the newly extruded pipe, the brush plate 512 is still in the storage state, and the water outlet state of the water outlet part 57 is in the atomization state, which will not affect the forming of the current pipe. When the rotating sleeve 55 gradually moves away from the output pipe, the release sleeve 59 is gradually and completely released;

[0058] As the release sleeve 59 is gradually released, the release sleeve 59 drives the push plate 510 to move backward synchronously. At this time, since the tooth block 5102 on the push plate 510 is set with a half shaft, when the tooth block 5102 moves forward, the tooth block 5102 no longer rotates, and can drive the driving gear 572 to rotate. The driving gear 572 rotates, and the synchronous ring 573 below is driven to rotate synchronously. The threaded rod 575 on the synchronous ring 573 also rotates synchronously. Due to the threaded connection setting, the rotation of the threaded rod 575 can push the impact block 576 to move upward, and the impact block 576 gradually moves upward. The water enters the water outlet step by step, so that the water flow becomes a high-speed impact water flow. At this time, because it is far away from the output pipe, the water flow impacts the cooled part and does not impact the soft part. The high-speed impact water flow can take away the heat on the pipe more quickly. At the same time, due to the gradual resetting of the release sleeve 59, the pressure rod 513 on the brush plate 512 moves out of the deep groove 514, and is squeezed by the inner wall of the release sleeve 59, pressing the brush plate 512 downward, so that the bristles of the brush plate 512 contact the surface of the pipe fitting, and the water flow can be used for brushing while cooling.

[0059] Then, when the left end of the rotating sleeve 55 contacts the inner wall of the left end of the cooling chamber 51, the release sleeve 59 and the movable sleeve 58 on the left side perform the same operation as the release sleeve 59 and the movable sleeve 58 on the right side, so that when the rotating sleeve 55 is reset by the reciprocating screw rod 53, the release sleeve 59 on the left side is slowly released to release the internal brush plate 512, and at the same time, the driving gear 572 is driven to rotate in the opposite direction, so that the impact block 576 moves out of the water outlet, and the high-speed water flow collides with the impact block 576 to generate water mist to reduce the impact force of the water flow. Finally, when the release sleeve 59 fits the inner wall of the right side of the cooling chamber 51, the pressure rod 513 in the right movable sleeve 58 directly enters the deep groove 514, so that when gradually approaching the output pipe, the brush plate 512 can be quickly retracted to avoid continuous brushing of the outer wall of the pipe just outputting the pipe to cause damage to the pipe. When the rotating sleeve 55 is reciprocated again by the reciprocating screw rod 53, the above operations are performed in sequence to continuously cool down and brush and clean at the same time.

[0060] And the water used for cooling in the above process will be discharged through the set pipeline.

[0061] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
