Description

Technical Field

[0001] The utility model relates to the technical field of plastic product feeding equipment, in particular to automatic feeding equipment for processing plastic products. Background Art

[0002] Plastic products are made of plastic, which are high molecular compounds formed by polyaddition or polycondensation reactions. They are commonly known as plastics or resins. They can freely change their composition and shape. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Plastic is the main raw material and various plastic products or components are made using processing technologies such as injection, extrusion, and hollow molding. When producing plastic products, an appropriate amount of plastic material needs to be poured into the processing equipment to process the plastic material for subsequent processing.

[0003] In the prior art: a Chinese patent document with publication number: CN219338466U and publication date of July 14, 2023 was proposed. The technical solution disclosed in the patent document is as follows: it includes a melting barrel, a feed barrel support frame and a molten plastic pushing mechanism, the melting barrel is fixedly mounted on the top of the support frame, the melting barrel is filled with plastic granular raw materials, the melting barrel is provided with a raw material stirring assembly and a raw material heating assembly, the feed barrel is fixedly mounted on the bottom of the melting barrel, the molten plastic pushing mechanism is arranged on the feed barrel, and a discharge pipe is fixedly mounted on the bottom of the melting barrel, and the end of the discharge pipe away from the melting barrel is fixedly mounted on the right side of the feed barrel. The utility model has a reasonable design and good practicality. It can automatically and quantitatively deliver molten plastic to the molding cavity of the plastic product production mold. There is no need for manual operation to add materials and manually control the amount of material added, which saves time and effort, improves the accuracy of feeding, and can change the amount of material added according to needs, with good use effect.

[0004] In the above technology, after the plastic raw materials are poured into the melting barrel, the melted raw materials enter the feed barrel through the discharge pipe. The push plate is adjusted to the upper set position in advance according to the required amount of raw materials. When the raw materials fill the space, the materials are fed into the mold cavity through the feed pipe. While feeding, the electric push rod pushes the push plate upward, so that the raw materials are output through the upper feed pipe. The raw material variables can be controlled in the above operations, but after the raw materials reach the feed barrel, the push plate is set at the bottom. Even if the push plate is in sealed contact with the inner wall of the feed barrel, the raw materials will still seep downward, and when the raw materials are output, the push plate is required to push the raw materials upward, which makes the workload of the electric push rod larger. Therefore, an automatic feeding equipment for plastic product processing is proposed. Utility Model Content

After starting the action, the plastic particles entering the interior of the hot melt barrel 1 are heated and melted, and then mixed by the stirring of the stirring blades 5;

[0024] A fixing frame 7 is set at the bottom of the hot melt tube 1. The fixing frame 7 consists of two rectangular plates and four straight rods in between. One of the rectangular plates of the fixing frame 7 is fixed to the bottom of the hot melt tube 1 by bolts. A quantity control component 8 is set at the other rectangular plate of the fixing frame 7. The quantity control component 8 includes a material storage box 801. The material storage box 801 and the fixing frame 7 are connected by bolts. An electric push rod 802 is fixed on the surface of the rectangular plate where the fixing frame 7 contacts the material storage box 801 by bolts. A circular hole is opened at a position coaxial with the push rod of the electric push rod 802 on the top of the rectangular plate of the fixing frame 7 and the material storage box 801. The push rod of the electric push rod 802 extends to the inside of the material storage box 801 through the circular hole, and a push rod end of the electric push rod 802 is welded. The limit plate 803 moves up and down with the push rod, and the moving distance of the electric push rod 802 is related to the amount of raw materials used. The movement of the limit plate 803 can be fixed by pre-setting. A baffle 805 is provided inside the storage box 801. A sealing rubber ring is glued to the side of the baffle 805. When the baffle 805 slides up and down inside the storage box 801, the sealing ring on the side fits with the inner wall of the storage box 801, so that after the raw materials enter the storage box 801, they will not penetrate to the top through the baffle 805. Four limit springs 804 are provided between the baffle 805 and the top of the storage box 801. The two ends of the four limit springs 804 are welded to the top of the storage box 801 and the top of the baffle 805 respectively.

[0025] A feeding pipe 807 is welded between the lower side of the hot melt cylinder 1 and the lower side of the storage box 801. A first control valve 808 is set in the middle of the feeding pipe 807. The first control valve 808 can control the raw materials to enter the storage box 801 through the hot melt cylinder 1. A discharge pipe 809 is welded at the bottom of the storage box 801. A second control valve 810 is set in the middle of the discharge pipe 809. The second control valve 810 can control whether the raw materials flow out of the storage box 801.

A support frame 9 is welded to the bottom of the hot melt tube 1, and the height of the support frame 9 is twice the height of the storage box 801, so that it will not affect the discharge of raw materials when placed on the ground.

[0026] Working principle: When in use, the utility model first pours the plastic granule raw material into the interior of the hot melt barrel 1 through the feed pipe 2, then starts the hot melter 6, and when the raw material is poured in, starts the drive motor 3. Under the drive of the drive motor 3, the stirring shaft 4 starts to rotate, and then drives the stirring blade 5 to start rotating. The stirring blade 5 cooperates with the hot melter 6 to heat and melt the plastic granules and fully mix and stir them. At this time, the electric push rod 802 is started according to the amount of raw material required, and the electric push rod 802 drives the limit plate 803 to move. After the limit plate 803 moves to the set position, the first control valve 80 is opened. 8. The raw materials enter the interior of the storage box 801 through the feed pipe 807. Under the pressure of the raw materials, the baffle 805 moves upward and compresses the limit spring 804. When the baffle 805 contacts the limit plate 803, it will stop moving, and the raw materials will be controlled to enter the storage box 801. At this time, the first control valve 808 is closed and the second control valve 810 is opened. The raw materials will be discharged through the discharge pipe 809 and then the plastic products will be made. During the discharge of the raw materials, the baffle 805 will move downward and then return to its initial state under the action of the rebound of the limit spring 804.
