Technical Field

[0001] The utility model relates to the technical field of feeding devices, and particularly relates to a novel automatic feeding device for PVC raw materials. Background Technique

[0002] Polyvinyl chloride plastic is polymerized from vinyl chloride monomers and is one of the commonly used thermoplastic plastics. Its trade name is simply referred to as "chloroplast", and its English abbreviation is PVC. Soft polyvinyl chloride can be made into better agricultural films and is often used to make raincoats, tablecloths, curtains, ticket clips, handbags, etc. It is also widely used in the manufacture of plastic shoes and artificial leather. The outermost skin of power cables is commonly made of PVC.

[0003] The existing patent document with the publication number CN221249508U discloses a plastic crushed material feeder. By setting a lifting mechanism, its feeding end can be raised or lowered, thereby changing the height of its feeding end, and then adapting to downstream equipment with different heights, which is beneficial to improving the applicability of the device. At the same time, the device is provided with a dust sweeping and dust collecting mechanism, which can sweep away plastic particles, sundries and dust adhering to the surface of the conveyor belt, thereby reducing impurities in the material and reducing the cleaning labor of personnel, which is beneficial to improving the practicability of the device.

[0004] Although the above-mentioned plastic crushed material feeder can solve corresponding technical problems, when the material is poured from the feed port onto the conveyor belt, some materials are likely to fall into the gap between the left side of the conveyor belt and the material storage bin, which not only causes waste of resources, but also causes jamming of the conveyor belt, thereby reducing the feeding effect of the material.

[0005] Therefore, a novel automatic feeding device for PVC raw materials is proposed. Content of the Utility Model

A conveyor belt is installed in the inner cavity of the material conveying trough body, and an opening is formed on one side of the material conveying trough body close to the downstream equipment.

[0012] As a preferred technical solution, the material storage mechanism includes a hopper located at the top of the material conveying trough body and on the side far away from the opening. Two symmetrically arranged connecting plates are fixedly connected between the hopper and the material conveying trough body.

A groove adapted to the baffle plate is formed on the side of the material conveying trough body far away from the opening, and the end of the rotating rod far away from the baffle plate movably penetrates through the groove to the outside of the material conveying trough body.

[0014] As a preferred technical solution, the surface of the rotating rod is rotationally connected to the penetrating part of the material conveying trough body through a rotating shaft.

[0015] As a preferred technical solution, the driving mechanism includes a gear fixedly connected to the surface of one of the rotating rods. The gear is located outside the material conveying trough body. An electric telescopic rod is arranged on one side of the material conveying trough body, and a rack meshing with the gear is fixedly connected to the output end of the electric telescopic rod.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 , this embodiment provides a novel automatic feeding device for PVC raw materials, including: a support 1, a feeding mechanism 2 for transporting PVC raw materials to its downstream equipment for processing, a storage mechanism 3 for storing PVC raw materials, and a material blocking mechanism 4 for blocking PVC raw materials.

[0027] Among them, the feeding mechanism 2 includes a feeding trough body 21 installed on the support 1, a conveyor belt 22 is installed in the inner cavity of the feeding trough body 21, an opening is provided on one side of the feeding trough body 21 close to the downstream equipment, and by starting the conveyor belt 22, the PVC raw materials can be transported into the downstream equipment through the opening to achieve the purpose of automatic feeding.

[0028] Among them, the material storage mechanism 3 includes a hopper 31 located at the top of the material conveying trough body 21 and far away from one side of the opening. Two symmetric connecting plates 32 are fixedly connected between the hopper 31 and the material conveying trough body 21. Through the material storage mechanism 3, PVC raw materials can be stored, and at the same time, the PVC raw materials can be poured onto the conveyor belt 22.

[0029] Among them, the top of the baffle 41 is in contact with the bottom of the hopper 31. A groove 43 adapted to the baffle 41 is provided on one side of the material conveying trough body 21 far away from the opening. One end of the rotating rod 42 far away from the baffle 41 passes through the groove 43 and extends to the outside of the material conveying trough body 21 through the groove 43, so that the baffle 41 can rotate up and down around the rotating rod 42 in the groove 43 and the inner cavity of the material conveying trough body 21 to realize the pouring and blocking operations of the PVC raw materials.

[0030] Among them, the surface of the rotating rod 42 is rotationally connected to the penetrating part of the material conveying trough body 21 through a rotating shaft to ensure the stability of the baffle 41 and the rotating rod 42 during rotation.

[0031] Among them, the driving mechanism 5 includes a gear 51 fixedly connected to the surface of one of the rotating rods 42. The gear 51 is located outside the material conveying trough body 21. An electric telescopic rod 52 is provided on one side of the material conveying trough body 21. The output end of the electric telescopic rod 52 is vertically fixedly connected with a rack 53 meshing with the gear 51. By starting the electric telescopic rod 52, the gear 51 can be driven to rotate, so as to realize the automatic rotation of the baffle 41 and the rotating rod 42, which can not only realize the automatic pouring and blocking operations, but also adjust the angle of the baffle 41 according to the actual use requirements to adjust the discharging rate.

[0032] Among them, a housing 54 is fixedly connected to one side of the material conveying trough body 21. The gear 51, the electric telescopic rod 52 and the rack 53 are all placed in the inner cavity of the housing 54, and the electric telescopic rod 52 is installed at the bottom of the inner wall surface of the housing 54.

[0034] The working principle of the present utility model is as follows: Start the electric telescopic rod 52 and the conveyor belt 22. The output end of the electric telescopic rod 52 drives the rack 53 to move upward. The rack 53 slides in the inner cavity of the guide sleeve 55. The teeth of the rack 53 drive the gear 51 to rotate clockwise. The gear 51 drives the rotating rod 42 and the baffle 41 to rotate synchronously, so that the baffle 41 rotates downward and opens with the rotating rod 42 as the axis. At this time, the PVC raw material in the inner cavity of the hopper 31 can fall onto the conveyor belt 22 through the discharge port of the hopper 31. The conveyor belt 22 can then transport the PVC raw material to its downstream equipment for processing, thus realizing automatic feeding operation. After the feeding is completed, start the electric telescopic rod 52 again, so that the output end of the electric telescopic rod 52 drives the rack 53 to move downward, and finally the baffle 41 rotates upward and closes with the rotating rod 42 as the axis, so as to block the discharge port of the hopper 31.
