Description

Technical Field

[0001] The utility model relates to a self-priming feeding device, in particular to a self-priming feeding device for plastic particles used in regeneration, belonging to the technical field of plastic recycling. Background Art

[0002] In the prior art, as disclosed in the utility model with the application number 202322363444.9, a self-priming feeding device for plastic recycling particles is disclosed. For the existing pneumatic conveying device for plastic particles, the suction end of the conveying pipe is usually directly placed into the box to suck the plastic particles. However, the plastic particles have a certain viscosity. When the suction port is directly inserted into the interior of the plastic particles, the number of particles fed simultaneously may be relatively large at the suction port, which easily causes blockage of the suction end, resulting in interruption of transportation and reduction of production efficiency. By providing a storage bin, the plastic particles are stored in the storage bin. When the plastic particles are conveyed by providing a dialing plate, the dialing plate can rotate along with the rotation of the rotating rod, and then scrape the upper end of the suction port of the first discharge pipe through the dialing plate, so as to prevent the plastic particles from accumulating at the suction port of the first discharge pipe and unable to enter the first discharge pipe, thereby ensuring the stability of transportation; when the dialing rod moves above the first discharge pipe, it can also briefly reduce the feeding area of the suction port at the first discharge end, so that a large amount of plastic will not enter the first discharge pipe at this time, and the problem that a large amount of plastic particles are continuously sucked into the interior of the discharge pipe for a long time, resulting in blockage of the interior of the discharge pipe, will not occur, further improving the transportation stability.

[0003] The similar applications currently have the following deficiencies:

[0004] The discharge pipe is installed at the bottom of the storage bin, and the suction method is to suck from the bottom of the storage bin. When there is raw material inside the storage bin, the discharge port will be directly buried. Although the use of the dialing rod increases the fluidity of the raw material, it cannot change the overall situation of the raw material coverage, and the surrounding materials will still block the air inlet, affecting the generation of negative pressure, and further affecting the suction of the materials;

[0005] Therefore, a self-priming feeding device for plastic particles used in regeneration is designed to optimize the above problems. Content of the Utility Model

[0006] The main purpose of the present utility model is to provide a self - suction feeding device for recycled plastic particles. By arranging the feeding pipe at the top of the storage tank, the raw materials will not bury the feeding pipe, effectively avoiding the blockage of the feeding pipe. In addition, by opening an anti - blockage port on the outer side of the bottom end of the feeding pipe, even if the bottom of the feeding pipe is buried, the gas can enter through the anti - blockage port and will not cause the blockage of the feeding pipe, ensuring the stable use of the device. By placing the feeding pipe on the top of the cross - plate, and the cross - plate is placed on the top of the material, during the use process, as the material decreases, the cross - plate and the feeding pipe will automatically move down. Then, using the translation mechanism composed of a motor, a reciprocating lead screw, a slider and a mounting block on the top of the cross - plate, the position of raw material suction can be automatically changed to ensure the uniform discharge of the raw materials inside the storage tank, with higher practicability. By rotatably installing a shaft rod on the outer side of the mounting block, and a brush and a gear are provided on the shaft rod, and used in cooperation with the rack on the cross - plate, during the reciprocating movement of the mounting block, the rotation of the shaft rod and the brush can be automatically controlled to loosen the raw materials inside the storage tank so that the raw materials can fall automatically.

[0026] The overall working principle is: before use, first lift the horizontal plate 4, then pour the plastic particles into the storage box 1 for storage, then put down the horizontal plate 4, and the bottom of the horizontal plate 4 fits on the top of the plastic particles, and then connect the top of the feeding tube 9 to the negative pressure device to generate negative pressure inside the feeding tube 9. The bottom end of the feeding tube 9 absorbs the plastic particles, and at the same time, the translation mechanism is used to control the mounting block 8 and the feeding tube 9 to move back and forth at both ends of the horizontal plate 4 to evenly absorb the raw materials inside the storage box 1. At the same time, after absorbing the raw materials at the bottom of the horizontal plate 4, the raw materials will automatically fall. At this time, the horizontal plate 4 will also automatically move down and automatically adjust the position of the horizontal plate 4. In addition, during the absorption process, even if the bottom end of the feeding tube 9 is completely covered, air can be introduced through the anti-blocking port 10 to ensure the suction inside the feeding tube 9.

[0027] In this embodiment, the bottom end of the feeding pipe 9 is a chamfered surface, and the chamfered surface faces upwards of the storage box 1 .

[0028] Partial working principle: Due to the setting of the beveled surface at the bottom end of the feeding tube 9, the bottom end of the feeding tube 9 is effectively prevented from being completely covered, thereby ensuring the suction effect.

[0029] In this embodiment, handles are provided at both ends of the outer side of the horizontal plate 4, and the shape of the handles is in the shape of a Chinese character "匚".

[0030] Local working principle: When controlling the upward movement of the cross plate 4, hold the handle and lift the cross plate 4 upward, which is practical and convenient.

[0031] In this embodiment, a transparent window is vertically opened on the outer side of the storage bin 1, and a slag discharge port is opened at the bottom of the side of the storage bin 1.

[0032] Local working principle: The opening of the transparent window can facilitate the observation of the storage volume inside the storage bin 1, and the design of the slag discharge port can facilitate the discharge of powdery slag.

[0033] In this embodiment, the translation mechanism includes a motor 5, a reciprocating lead screw 6 and a slider 7. The motor 5 is fixed at one end of the top of the cross plate 4, the output end of the motor 5 is equipped with a reciprocating lead screw 6 parallel to the cross plate 4, the reciprocating lead screw 6 is equipped with a slider 7, and the slider 7 is fixed inside the mounting block 8.

[0035] In this embodiment, the loosening mechanism includes a shaft rod 11, a gear 12 and a rack 13. The shaft rod 11 is vertically and rotatably installed on the side of the mounting block 8, a brush is provided at one end of the shaft rod 11 away from the mounting block 8, a gear 12 is fixed at one end of the shaft rod 11 close to the mounting block 8, and a rack 13 is provided along the length direction at the top of the cross plate 4, and the shaft rod 11 meshes with the rack 13.

[0036] Local working principle: During the movement of the mounting block 8, the gear 12 will move along the length direction of the rack 13, and at the same time the gear 12 will also rotate. The gear 12 drives the shaft rod 11 to rotate, and the shaft rod 11 will sweep off the raw materials during rotation to loosen the raw materials.

[0037] In this embodiment, the shaft rod 11 passes through the bottom end of the feeding pipe 9, and a dial rod 14 is provided at the position of the outer side of the shaft rod 11 inside the feeding pipe 9.

[0038] Local working principle: During the rotation of the shaft rod 11, the dial rod 14 will be driven to rotate, so as to disperse the raw materials drawn into the feeding pipe 9 and avoid the blockage of the feeding pipe 9.
