Description

Technical Field

[0001] The utility model relates to the technical field of the material suction structure of an injection molding machine, in particular to a material suction structure of an injection molding machine for children's bicycle tires. Background Technique

[0002] With the improvement of people's living standards, people have more and more demands for children's bicycles. The traditional structure of children's bicycle tires includes an outer tire, an inner tire and a wheel hub. The children's bicycle tires are formed by assembling each component after separate production, which has high production costs, low production efficiency and the hidden danger of tire bursting for the inflatable inner tire. Therefore, the traditional children's bicycle tires are gradually replaced by integrally molded injection tires. In order to improve the injection production efficiency and reduce manual handling of raw materials, an automatic material suction structure is needed.

[0003] For example, the patent document CN216506408U discloses a material suction device for injection molded parts, including: a through pipe, one end of the through pipe is connected with a discharge pipe, and the other end of the through pipe is connected with a feed pipe. A feed hopper is arranged at the end of the feed pipe away from the through pipe; a card slot is opened on the surface of the feed hopper, and a docking plate is arranged on one side of the feed hopper. A filter screen is arranged inside the docking plate, and a docking seat for docking with the opening of the feed hopper is arranged on one side of the docking plate; a card strip is arranged on the outer side of the docking plate close to the docking seat, and a spring is connected to the inner side of the card strip. A rotating shaft is arranged on the outer side of the docking plate, and a mounting plate is arranged on the outer side of the rotating shaft; however, there are still many deficiencies in this prior art. For example: it is necessary to manually carry raw materials and add them into the feed hopper, and even it is necessary to disassemble the raw materials in large-size packages and then add them manually. The addition of raw materials is neither convenient nor smooth, resulting in low production efficiency. At the same time, a large number of manual operations increase the production cost, and there are also potential safety hazards in production. Content of the Utility Model

[0012] As a further improvement to the above solution, the discharge port is connected to an injection molding system, which includes a melting tube and an injection molding chamber. The right side of the melting tube is connected to the injection molding chamber, and the left side of the melting tube is connected to a mold clamping chamber.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, a driving motor is connected to a crank through a gearbox. A sliding sleeve is rotatably connected to the outside of the crank. The sliding sleeve is sleeved on the outer edge of a swing rod and slides up and down along the swing rod. Both the upper and lower ends of the swing rod are fixedly connected with mounting blocks. A mounting frame is fixedly connected to the right sides of the two mounting blocks. A part of the mounting frame extends horizontally outward to mount a rodless cylinder. A sliding frame is mounted on the slider of the rodless cylinder, and a suction gun is mounted on the sliding frame. The crank converts the rotational power of the driving motor into the periodic reciprocating swing of the mounting frame, enabling the suction gun to evenly pick up materials from the naturally formed arc surface on the upper layer of the raw materials. The swing of the suction gun can also disturb the raw material layer piled up away from the center, mixing and leveling the raw materials evenly, facilitating the uniform suction of raw materials by the suction gun. At the same time, the suction gun reciprocates on the rodless cylinder along with the sliding frame, cooperating with the reciprocating swing to expand the picking area and ensure smooth and uniform material picking. Further, the crank includes an input block and an output block. A chute is provided on the side wall of the input block, and a number of threaded holes are provided on both sides of the chute. A distance-adjusting slider is fixedly connected to the side wall of the output block, and a number of threaded holes are provided on both sides of the distance-adjusting slider. The output block is slidably mounted on the input block, and bolts are fixed by the cooperation of the number of threaded holes. By the relative sliding of the input block and the output block, the length of the crank is adjusted, thereby changing the swing angle of the swing rod to adapt to the disturbance and leveling of different raw materials.

[0015] In the present utility model, plowing blocks are symmetrically and fixedly connected to the side wall of the suction gun. A cavity is provided inside the plowing block. One end of the cavity close to the feed port of the suction gun is closed, and the other end of the cavity away from the feed port of the suction gun is open. A through hole communicating with the cavity is provided on the side wall of the suction gun close to the feed port. The plowing blocks can reduce the resistance when the suction gun moves in the raw materials, and at the same time disperse the raw materials for easy suction. When suction is carried out, the upper ends of the plowing blocks are exposed to the air. Air enters the suction gun from the through hole through the cavity inside the plowing blocks. The air is mixed with the raw materials at the lower end of the suction gun and is sucked into the feeding hopper, preventing the raw materials from blocking the suction gun and the suction pipe and making the suction more smooth.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0026] A material suction structure of a baby carriage tire injection molding machine, as Figure 1 and Figure 2As shown in the figure, it includes a material suction gun 1 and a material suction pipe 2, and is characterized in that: a sliding frame 3 is sleeved on the side wall of the material suction gun 1, a cylinder slider 42 is connected to the outside of the sliding frame 3, the cylinder slider 42 is installed in a rodless cylinder 41, and the material suction gun 1 reciprocates on the rodless cylinder 41 along with the sliding frame 3, so that the material suction gun 1 can evenly suck raw materials. Both ends of the rodless cylinder 41 are jointly connected with a mounting frame 4, and the rodless cylinder 41 is installed on the horizontally extending part of the mounting frame 4, so that the material suction gun 1 can adapt to raw material barrels of different sizes and evenly suck raw materials. At the upper and lower ends of the left side of the mounting frame 4, mounting blocks 43 are fixedly connected, and a swing rod 44 is jointly fixed by the two mounting blocks 43.

[0027] As Figures 1 to 4 shown, a lifting platform 5 is connected to the top of the mounting block 43 through a hinge seat. A driving motor 52 is fixedly installed on the lifting platform 5. The output end of the driving motor 52 is connected to a crank 7 through a reducer. The crank 7 includes an input block 72 and an output block 73. A chute 721 is opened on the side wall of the input block 72, and a number of threaded holes 74 are opened on both sides of the chute 721. A distance-adjusting slider 731 is fixedly connected to the side wall of the output block 73, and a number of threaded holes 74 are opened on both sides of the distance-adjusting slider 731. The output block 73 is slidably installed on the input block 72, and a bolt 75 is fixed by the cooperation of a number of threaded holes 74. By the relative sliding of the input block 72 and the output block 73, the length of the crank 7 can be adjusted, thereby changing the swing angle of the swing rod 44, and then the bolt 75 is used to pass through the threaded hole 74 for fixation. A sliding sleeve 71 is rotatably connected to the outside of the crank 7. The sliding sleeve 71 is sleeved outside the swing rod 44 and slides up and down along the swing rod 44. While the sliding sleeve 71 slides on the swing rod 44, it acts together with the crank 7 to push the swing rod 44 to swing reciprocally, converting the rotational output of the driving motor 52 into the reciprocal swing of the swing rod 44.

[0028] As Figure 1 and Figure 2 shown, the lifting platform 5 is slidably installed up and down in a moving frame 6. A number of lifting cylinders 51 are fixedly connected to the bottom plate of the moving frame 6. The upper ends of the number of lifting cylinders 51 are jointly connected to the lower end of the lifting platform 5. The lifting cylinders 51 lift the entire lifting platform 5 so as to move the material suction gun 1 above the raw materials and then insert it into the raw materials for suction operation. A handle 61 is fixedly installed on the side wall of the moving frame 6, and a number of universal wheels 62 are fixedly installed at the lower end of the moving frame 6. When the raw materials are sucked and replaced, the material suction gun 1 can be quickly and easily transferred, reducing the workload of workers and improving work efficiency.

[0029] As Figure 6 and Figure 7As shown in the figure, the discharging end of the material suction pipe 2 is connected to a feeding system 8. The feeding system 8 includes a feeding hopper 81 and a working hopper 82. A suction pipe 83 is connected to the side wall of the feeding hopper 81. The suction pipe 83 is connected to a suction machine 84. A negative pressure environment in the feeding hopper 81 is formed through the suction machine 84, and raw materials are sucked into the feeding hopper 81 through the material suction gun 1. The lower end of the feeding hopper 81 is connected to the working hopper 82. The setting of the feeding hopper 81 does not affect the normal operation of the working hopper 82 during intermittent material suction. A viewing window 821 is provided on the side wall of the working hopper 82, which is convenient for observing the stock volume of the working hopper 82 to judge whether material suction is required, so as to avoid storing excessive raw materials in the working hopper 82. A hot air dryer 822 is provided on the side wall of the working hopper 82. The air outlet of the hot air dryer 822 is connected to a hot air pipe 823. The hot air pipe 823 communicates with the working hopper 82, and the raw materials in the working hopper 82 are dried by hot air to prevent the raw materials from sticking to each other and avoid clogging of the discharge port. The lower end of the working hopper 82 is connected to a discharge port 85.

[0030] As Figure 6 shown, the discharge port 85 is connected to an injection molding system 9. The injection molding system 9 includes a melting tube 91 and an injection molding chamber 92. The right side of the melting tube 91 is connected to the injection molding chamber 92, and the left side of the melting tube 91 is connected to a mold clamping chamber 93. The melting tube 91 heats and melts the raw materials according to the raw material characteristics and processing requirements. The injection molding chamber 92 injects the raw materials in a fluid state into the mold in the mold clamping chamber 93 to produce injection molded products of different shapes and specifications.

[0031] During the operation of Embodiment 1, the feeding system 8 is connected to the injection molding system 9, the material suction pipe 2 is connected to the feeding hopper 81, the feeding end of the material suction pipe 2 is connected to the upper end of the material suction gun 1, the material suction gun 1 is fixed on the sliding frame 3, the moving frame 6 is pushed to the place where the raw materials are to be sucked, the bolt 75 is removed, and after adjusting the crank length by sliding the input block 72 and the output block 73 according to the required swing angle, it is fixed with the bolt 75. The lifting cylinder 51 is started to raise the lifting platform 5 so that the lower end of the material suction gun 1 is higher than the raw materials. The moving frame 6 is pushed so that the material suction gun 1 is located above the raw materials. The lifting cylinder 51 is started to lower the lifting platform 5 so that the lower end of the material suction gun 1 is inserted into the raw materials. The feeding system 8, the injection molding system 9, the rodless cylinder 41 and the driving motor 52 are started. While the material suction gun is sucking materials, it swings back and forth and moves left and right reciprocally to take materials and disturb and level the arc surface naturally formed by the upper-layer raw materials. As the material taking progresses, the height of the lifting platform 5 is gradually adjusted to ensure continuous and uniform material suction. Embodiment

[0032] Embodiment 2 is based on Embodiment 1. As Figure 1 and Figure 5As shown in the figure, a suction pipe 2 is connected to the upper end of the suction gun 1. Symmetrically fixed to the side wall of the suction gun 1 are plowing blocks 21. The cross-section of the plowing blocks 21 is triangular, and the resistance during movement in the raw material is relatively small. A cavity 22 is formed inside the plowing blocks 21. One end of the cavity 22 close to the feed inlet of the suction gun 1 is closed, and the end of the cavity 22 far from the feed inlet of the suction gun 1 is open. A through hole 23 communicating with the cavity 22 is formed in the side wall of the suction gun 1 near the feed inlet. When sucking the raw material, the upper end of the plowing block 21 is exposed to the air, and the air enters the suction gun 1 from the through hole 23 through the cavity 22 inside the plowing block 21.

[0033] During the operation of Embodiment 2, the suction gun 1 is inserted into the raw material to a certain depth. The plowing blocks 21 can reduce the resistance when the suction gun 1 moves in the raw material, avoid damaging parts such as the drive motor 52, and at the same time break up and level the raw material, which is also convenient for suction. When the suction gun 1 is inserted, the upper end of the plowing block 21 remains in communication with the air, and the air enters the suction gun 1 from the through hole 23 through the cavity 22 inside the plowing block 21. The air is mixed with the raw material at the lower end of the suction gun 1 and is sucked into the feeding hopper 81, avoiding the blockage of the suction gun 1 and the suction pipe 2 by the raw material and making the suction smoother.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
