Description

Technical Field

[0001] This invention relates to the technical field of feeding equipment, and in particular to a feeding tube head anti-shortage device. Background Technology

[0002] Large blow molding machines typically use a material suction machine to transport plastic granules or other raw materials into the hopper or barrel of the blow molding machine, thereby ensuring continuous and stable production.

[0003] When feeding materials, the suction pipe is usually inserted directly into the raw material bucket below, drawing the plastic granules from the bucket into the material cylinder at the top of the blow molding machine. However, some plastic granules are sticky, and others are prone to clumping due to moisture, preventing the plastic granules and air from forming a suitable air-material mixture ratio. This causes material to accumulate in the suction pipe, leading to blockages and resulting in a lack of material in the blow molding machine. Once a blockage occurs, operators cannot immediately detect the blockage in the suction pipe, which also affects the production quality of the blow-molded products.

[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems:

[0005] Existing blow molding machines are prone to clogging of the suction pipe during raw material delivery, leading to material shortages that operators cannot detect in time, thus affecting the production quality of blow-molded products. Summary of the Invention

[0006] The purpose of this invention is to provide a material shortage prevention device for the suction pipe head, which solves the technical problem that the suction pipe of the existing blow molding machine is easily blocked during raw material transportation, resulting in material shortage in the blow molding machine, and the operators cannot detect it in time, which affects the production quality of blow molded products.

[0018] Beneficial Effects: The material shortage prevention device for the suction pipe head provided by this invention involves installing the pipe head mechanism onto the suction pipe and placing it into a bucket containing plastic granules. The motor is started, driving a turntable to rotate, which in turn drives a feeding device. The plastic granules enter the suction pipe through the gap between the support legs and the base. When encountering clumps of plastic granules, the feeding device peels them off piece by piece to prevent blockage.

[0037] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] This embodiment provides a material shortage prevention device for the suction pipe head. Please refer to... Figure 1-5 As shown, the device includes a pipe head mechanism 100, a material feeding mechanism 200, a crushing frame 300, and an alarm mechanism 400. The pipe head mechanism 100 includes a pipe cylinder 110, several support legs 140, and a base 130. One end of each support leg 140 is fixedly connected to the pipe cylinder 110, and the other end is fixedly connected to the base 130. The material feeding mechanism 200 includes a motor 210, a turntable 220, and several material feeding components 230. The motor 210 is located at one end of the base 130, and the turntable 220... Located at the other end of the chassis 130, the turntable 220 is connected to the motor 210 for transmission, and the material feeding component 230 is connected to the turntable 220; the crushing frame 300 is fixedly connected to the inner wall of the tube 110; the alarm mechanism 400 includes a pressure sensor 410 and a buzzer alarm 420; the pressure sensor 410 is installed on the crushing frame 300, and the buzzer alarm 420 is installed on the tube 110 and is electrically connected to the pressure sensor 410.

[0039] Specifically, the tube head mechanism 100 is used to connect with the suction pipe, and four support legs 140 are provided. The support legs 140 are connected to the tube 110 and the chassis 130, which allows plastic particles to enter the tube 110 from the side, reducing the accumulation of plastic particles at the head of the tube 110. The feeding mechanism 200 is used to feed the plastic particles at the head of the tube 110. The motor 210 is a reciprocating motor, which can make the turntable 220 and the feeding component 230 rotate back and forth, thereby increasing the feeding effect. The crushing frame 300 prevents clumps of plastic particles from entering the suction pipe, making the plastic particles enter the suction pipe more evenly. When plastic particles accumulate at the opening of the tube 110, the accumulated plastic particles will squeeze the pressure sensor 410, thereby the pressure sensor 410 transmits a signal to the buzzer alarm 420 to sound an alarm and remind the operator that the tube 110 is blocked. In use, the tube head mechanism 100 is installed on the suction pipe and placed into a bucket containing plastic granules. The motor 210 is started, which drives the turntable 220 to rotate. The turntable 220 drives the feeding component 230 to rotate. The plastic granules enter the suction pipe through the gap between the support leg 140 and the base 130. When encountering clumps of plastic granules, the feeding component 230 will peel off the clumps to prevent the plastic granules from clogging the suction pipe. At the same time, the crushing frame 300 will break up the plastic granules entering the suction pipe to prevent blockage. When the plastic granules accumulate in the tube 110, they will push the pressure sensor 410. At this time, the pressure sensor 410 will transmit a signal to the buzzer alarm 420, which will sound an alarm to promptly remind the staff that the suction pipe is blocked.

[0040] In this embodiment, one end of the tube 110 is provided with a thread 111.

[0041] Specifically, the thread 111 facilitates the detachable connection between the tube 110 and the suction pipe, and the connection is tighter, preventing the tube 110 from separating from the suction pipe during operation.

[0042] In this embodiment, the chassis 130 is provided with a groove 131, which is adapted to the turntable 220.

[0043] Specifically, the size of the groove 131 is the same as that of the base plate, and the groove 131 is designed to prevent plastic particles from entering between the turntable 220 and the base plate 130.

[0044] In this embodiment, the material feeding component 230 includes an arc-shaped cylinder 231, a rotating shaft 232, and a plurality of material feeding frames 233; the arc-shaped cylinder 231 is fixedly connected to the turntable 220, the rotating shaft 232 is rotatably connected to the turntable 220, and the material feeding frames 233 are fixedly connected to the rotating shaft 232.

[0045] Specifically, when the turntable 220 rotates, the rotating shaft 232 and the feeding frame 233 will rotate due to centrifugal force. The feeding frame 233 will push the plastic particles, so that the plastic particles enter the suction tube more evenly. The arc-shaped cylinder 231 limits the swing angle range of the feeding frame 233. The reciprocating rotation of the motor 210 can make the feeding frame 233 swing back and forth, so that the plastic particles enter the suction tube more evenly.

[0046] In this embodiment, the arc-shaped cylinder 231 is fixedly connected with a reinforcing ring 240.

[0047] Specifically, the reinforcement ring 240 enhances the connection strength of each arc-shaped cylinder 231.

[0048] In this embodiment, the crushing frame 300 includes a plurality of crushing rods 310 and crushing seats 320; one end of the crushing rod 310 is connected to the inner wall of the tube 110, and the other end is connected to the crushing seat 320.

[0049] Specifically, there are four crushing rods 310, which are conical in shape to allow plastic particles to enter the suction pipe evenly. The crushing seat 320 is set on the central axis of the tube 110 and is used to install the pressure sensor 410.

[0050] In this embodiment, the breaking rod 310 is provided with a wire groove 311, and the tube 110 is provided with an installation groove 112, and the wire groove 311 is connected to the installation groove 112.

[0051] Specifically, the wire groove 311 is used to install the wire between the pressure sensor 410 and the buzzer alarm 420, thereby preventing the wire from floating inside the tube 110, and the mounting groove 112 is used to install the buzzer alarm 420.

[0052] In this embodiment, a limiting ring 120 is fixedly connected to the outer wall of the tube 110, and a limiting post 510 is detachably connected to the limiting ring 120. The limiting post 510 is connected to a raw material barrel 500.

[0053] Specifically, the limiting ring 120 and the limiting post 510 work together to allow the tube 110 to move up and down in the raw material barrel 500, preventing the tube head mechanism 100 and the feeding mechanism 200 from moving randomly inside the raw material barrel 500.

[0054] In this embodiment, the raw material barrel 500 is provided with an inclined chamber 520, and the lowest end of the inclined chamber 520 is located at one end of the limiting post 510.

[0055] Specifically, the tilting chamber 520 is designed so that plastic granules can continuously flow into the area below the tube head mechanism 100.

[0056] In this embodiment, the raw material barrel 500 is provided with a limiting block 530, and the limiting block 530 is detachably connected with a figure-eight ring 540, which is detachably connected to the limiting post 510.

[0057] Specifically, after the limiting ring 120 is fitted onto the limiting post 510, the figure-eight ring 540 is installed onto the limiting block 530 and the limiting post 510 to prevent the limiting post 510 from shaking on the raw material barrel 500, thereby making the tube 110 move stably on the raw material barrel 500.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
