The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0028] For example, see Figure 1 to Figure 6 In the embodiment of the present invention, a rope skipping adaptive extrusion molding machine includes a support mounting plate 3, a support mounting frame 4 is provided on one side of the support mounting plate 3, and a plurality of fixed mounting holes are provided on the support mounting frame 4, characterized in that it also includes

[0031] The scraper and cut-off mechanism is used for cutting and scraping at the injection molding of the skipping rope, and includes a swing mounting frame 9, a linkage mounting frame 21, and a tool 19; a driving shaft 5 connected between the support mounting plate 3 and the swing mounting frame 9, the swing mounting frame 9 and the linkage mounting frame 21, and the linkage mounting frame 21 and the tool 19.

[0032] The device is installed at the target position through the support mounting frame 4, and the transfer guide barrel 11 is connected to the external molten material feeding device, and the external raw materials are introduced into the transfer guide barrel 11. When the material inside the transfer guide barrel 11 reaches a certain amount, the defoaming module changes the pressure inside the transfer guide barrel 11, so that the bubbles in the material inside the transfer guide barrel 11 quickly float up and are discharged, so as to improve the quality of the plastic skipping rope;

[0033] The defoamed material is quantitatively extruded and formed under the action of the defoaming module, and the extruded material is captured by the air duct guide cylinder 41 in the air duct shaping and guiding module, and is smoothly guided and quickly formed under the action of the air duct formed inside, which significantly improves the efficiency and quality of the plastic skipping rope molding;

[0034] In the gap of raw material extrusion molding, the mounting frame 9 is swung under the action of the driving shaft 5, and the linkage mounting frame 21 rotates a corresponding angle, so that the tool 19 can cut and scrape the material at the extrusion molding under the action of the driving shaft 5, thereby ensuring the improvement of the finished product of the plastic skipping rope.

[0035] Example 2, based on Example 1, please refer to Figure 1 to Figure 3 In the embodiment of the present invention, the defoaming and material guiding mechanism further comprises an internal threaded mounting cylinder 10 matched with an external threaded mounting cylinder 16, a solenoid valve is arranged in the external threaded mounting cylinder 16, a variable diameter extrusion material guiding cylinder 18 is arranged at one end of the internal threaded mounting cylinder 10, an operating cylinder 17 is symmetrically arranged on the outer wall of the internal threaded mounting cylinder 10, the defoaming and material guiding mechanism further comprises a feed mounting cylinder 1 arranged on the transfer material guiding cylinder 11 at the end of the defoaming module, a connecting flange is arranged at the outer end of the feed mounting cylinder 1, a solenoid valve 2 is arranged in the feed mounting cylinder 1, and the defoaming module comprises a variable pressure cylinder 14, One end of the transformer cylinder 14 is connected to the transfer guide cylinder 11 through a connecting mounting cylinder 12, an exhaust duct 13 is extended from the transfer guide cylinder 11 on one side of the connecting mounting cylinder 12, an anti-splashing variable-diameter guide cylinder 36 is arranged inside the connecting mounting cylinder 12, an electromagnetic valve is arranged inside the anti-splashing variable-diameter guide cylinder 36, an electromagnetic overflow valve 20 is arranged inside the exhaust duct 13, and a driving telescopic column 34 is arranged on the other end of the transformer cylinder 14 through a guide mounting frame 33, a piston disk 35 is arranged inside the transformer cylinder 14, and the outer end of the driving telescopic column 34 is connected to the piston disk 35.

[0036] Specifically, the corresponding diameter extrusion guide cylinder 18 is selected according to the needs, and the installation is realized under the cooperation of the internal thread installation cylinder 10 and the external thread installation cylinder 16 thereon. At this time, the operating cylinder 17 cooperates with the external plug-in lever principle to improve the efficiency and quality of the installation;

[0037] The feed installation barrel 1 is connected to the external molten material feeding equipment by matching the connecting flange. The solenoid valve 2 on the feed installation barrel 1 controls the material to be introduced into the transfer guide barrel 11. When a certain amount of material is reached, only the solenoid valve on the anti-splashing variable diameter guide barrel 36 is opened. Under the action of the driving telescopic column 34, the piston disc 35 is moved upward to reduce the pressure in the transfer guide barrel 11, so that the bubbles of the material in the hot melt state float up quickly. Then all the solenoid valves are closed and the piston disc 35 is moved in the reverse direction. At this time, the gas is discharged from the exhaust conduit 13 through the electromagnetic overflow valve 20, and the solenoid valve on the anti-splashing variable diameter guide barrel 36 is opened again;

[0038] After repeating the above operation several times, close all the solenoid valves, lift the piston disk 35 to the target position according to the amount of consumables for a single injection molding of the skipping rope, open the solenoid valve on the anti-splash reducing guide cylinder 36 and the solenoid valve in the external threaded mounting cylinder 16, and close the solenoid overflow valve 20. At this time, the piston disk 35 moves downward, and the hot-melt raw material of the corresponding amount of consumables is extruded from the reducing extrusion guide cylinder 18 to complete the quantitative injection molding operation.

[0039] Example 3, based on Example 1, please refer to Figure 1-2 and Figures 4 to 6 In the embodiment of the present invention, the adjustment and displacement module also includes a guide column 26 arranged on the displacement screw barrel 29, and the support mounting plate 3 is provided with a guide hole 27 in cooperation with the guide column 26. A limit mounting plate 24 is symmetrically arranged on one side of the support mounting plate 3 in cooperation with the guide hole 27. A driving motor 25 is arranged on the limit mounting plate 24 on one side, and the driving motor 25 is connected to a displacement stud 38 through a rotating shaft. The displacement stud 38 is arranged in cooperation with the displacement screw barrel 29, and the other end of the displacement stud 38 extends out of the limit mounting plate 24 on the other side. Conductive sliders 30 are symmetrically arranged on the outer side of the displacement screw barrel 29, and conductive slide rails 37 are symmetrically arranged between the opposite limit mounting plates 24 in cooperation with the conductive sliders 30.

[0040] The displacement stud 38 is rotated by driving the motor 25, and the displacement screw barrel 29 is guided and displaced under the action of the guide column 26 and the guide hole 27. At the same time, the conductive slider 30 and the conductive slide rail 37 slide, and the power supply is coupled to ensure stable power supply to the air duct shaping and material guiding module.

[0041] Example 4, based on Example 1, please refer to Figures 4 to 6 In the embodiment of the present invention, the air duct shaping and material guiding module also includes an air duct guide tube 41 and a variable diameter curling portion 42 arranged inwardly at the other end of the variable diameter mounting tube 8, and a fan 7 is arranged on the displacement mounting plate 6. One end of the fan 7 is connected to the annular hood 31 through a conduit 23, and the other end of the fan 7 is provided with a dust filter 28.

[0042] An annular drainage tube 22 is arranged on the outside of the air duct guide tube 41, and the annular drainage tube 22 extends outward and is provided with a connecting guide tube 32. An annular water-absorbing sponge 40 is arranged inside the annular drainage tube 22. A plurality of evaporation fins 39 are arranged at equal angles on the inner wall of the air duct guide tube 41. The annular water-absorbing sponge 40 extends into the air duct guide tube 41 and is connected to one end of the evaporation fin 39.

[0043] The external air is introduced into the air duct guide tube 41 through the fan 7, and is input into the space between the variable diameter installation tube 8 and the annular hood 31 through the conduit 23, and then directed to the variable diameter curling part 42. As the guide cross section continues to decrease, the air finally flows to the inner wall of the air duct guide tube 41 through the variable diameter curling part 42 at a high speed, forming a cylindrical air duct. At this time, the air pressure at one end of the air duct guide tube 41 is significantly higher than that at the other end, and the extruded raw materials are sucked into the air duct guide tube 41, but they will not collide with them under the action of the cylindrical air duct. At the same time, the high-speed guided air allows the extruded materials to be quickly formed.

[0044] The connecting guide tube 32 is connected to an external water supply device. Water enters the annular guide tube 22 through the connecting guide tube 32 and penetrates into each evaporation fin 39 through the annular water-absorbing sponge 40. As the high-speed guided air evaporates, the temperature of the airflow discharged from the variable diameter curling part 42 is significantly reduced, further improving the speed of plastic film forming.

[0045] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
