Description

Technical Field

[0001] The utility model belongs to the technical field of pickle ball rotational molding processing, and particularly relates to a feeding device for a small rotationally molded ball. Background Art

[0002] Pickleball is a hollow plastic ball that combines the characteristics of badminton, tennis and table tennis. When processing pickleball, it needs to be processed using rotational molding equipment. Rotational molding is a thermoplastic plastic hollow molding method. This method is to first add the plastic raw material into the mold, and then the mold is continuously rotated along two vertical axes and heated. Under the action of gravity and heat energy, the plastic raw material in the mold is gradually and evenly coated, melted and adhered to the entire surface of the mold cavity, formed into the required shape, and then cooled and shaped into a finished product.

[0003] Currently, the loading of small roto-molded spheres in large-scale production is done manually. For the loading operation of multiple sets of molds, workers align the funnel with the molds one by one, and then add the raw materials into the molds through the funnel to complete the loading operation. This operation method has low production efficiency and increases time and labor costs. Moreover, the labor intensity of workers aligning the materials with the molds one by one is high and it is easy to cause fatigue, which may lead to inaccurate feeding and affect production operations. Utility Model Content

[0004] The purpose of the present utility model is to provide a feeding device for small roto-molded spheres to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a feeding device for small roto-molded spheres, comprising:

[0006] The lower mold base has one end hingedly connected to the upper mold base by a hinge, the surface of the lower mold base is evenly distributed with a number of lower mold bins, the surface of the upper mold base is evenly distributed with a number of upper mold bins, the lower mold bins and the upper mold bins are used to process rotationally molded spheres after being combined with the upper mold bins, and the lower mold base is provided with a loading plate, the surface of the loading plate is evenly distributed with a number of upper hoppers matching the number of lower mold bins, and the raw materials are poured into the upper hopper so that the raw materials in the upper hopper can leak into the lower mold bin.

[0007] Preferably, a sealing groove is provided on the top surface of the lower mold bin, and a sealing ring is connected to the bottom surface of the upper mold bin. After the upper mold bin is rotated by a hinge and closed with the lower mold bin, the sealing ring is inserted into the sealing groove.

[0008] Preferably, the surfaces of the lower die base, the upper die base and the loading plate are all provided with a plurality of grooves.

[0009] Preferably, two groups of circular rings are connected to the surface of the upper die seat.

[0010] Compared with the prior art, the upper end of the utility model has the advantages of

[0011] (1) the feeding device can simultaneously feed multiple lower die bins through the design of the feeding plate and the feeding hopper, greatly improving the feeding speed compared with manually feeding one by one through the funnel, thereby improving the overall production efficiency.

[0012] (2) the lower die seat and the upper die seat are hingedly connected through the hinge, so that the molds can be relatively opened, facilitating the inspection of the amount of raw materials in the lower die bin after the feeding is completed and the feeding plate is removed, ensuring that the amount of raw materials in each lower die bin meets the production requirements, and avoiding insufficient or excessive amount of raw materials, which leads to product defects.

[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0017] The utility model provides a kind of feeding device of small-sized rotational moulding sphere as Figure 1-2 It is shown in the figure, including:

[0018] Lower die seat 1, the lower die seat 1 one end is hingedly connected with upper die seat 3 through hinge 2, the lower die seat 1 surface is evenly distributed with several lower die bins 4, the upper die seat 3 surface is evenly distributed with several upper die bins 5, the lower die bin 4 is combined with upper die bin 5 after moulding and is used for processing rotational moulding sphere, the lower die seat 1 is equipped with feeding plate 6, the feeding plate 6 surface is evenly distributed with several feeding hoppers 7 matched with the number of lower die bin 4, by pouring raw material into the feeding hopper 7, so that the raw material in feeding hopper 7 leaks into lower die bin 4.

[0019] The top surface of the lower mold bin 4 is provided with a sealing groove 8, and the bottom surface of the upper mold bin 5 is connected with a sealing ring 9. After the upper mold bin 5 is rotated by the hinge 2 and closed with the lower mold bin 4, the sealing ring 9 is inserted into the sealing groove 8.

[0020] The surfaces of the lower die base 1, the upper die base 3 and the loading plate 6 are all provided with a plurality of grooves 10. Without affecting their structural strength and normal use functions, a part of the material is removed through the grooves 10, thereby effectively reducing the overall weight and making it easier for operators to move the mold.

[0021] Two groups of circular rings 11 are connected to the surface of the upper die base 3 , and the circular rings 11 facilitate pulling the upper die base 3 to rotate through the hinge 2 .

[0022] The feeding device of the small roto-molded sphere is provided with a feeding plate 6 on the lower mold base 1. The surface of the feeding plate 6 is evenly distributed with a number of feeding hoppers 7 that match the number of the lower mold bin 4. When the feeding operation is performed, the raw material is poured into the upper hopper 7. Since the upper hopper 7 corresponds to the lower mold bin 4 in position, the raw material leaks from the upper hopper 7 into the lower mold bin 4 under the action of gravity. When the upper hopper 7 is blocked by falling materials, the upper hopper 7 or the feeding plate 6 can be gently tapped to loosen the blocked raw material through vibration and continue to fall, thereby realizing the process of conveying the raw material into the lower mold bin 4. After the raw material is conveyed, the upper hopper 7 can be withdrawn;

[0023] Since the upper mold base 3 is hinged to one end of the lower mold base 1 by the hinge 2, the upper mold base 3 can be rotated around the hinge 2 after loading is completed, so that the several upper mold bins 5 evenly distributed on the surface of the upper mold base 3 correspond one to one with the several lower mold bins 4 evenly distributed on the surface of the lower mold base 1. At this time, the sealing ring 9 connected to the bottom surface of the upper mold bin 5 gradually approaches the sealing groove 8 on the top surface of the lower mold bin 4 as the upper mold bin 5 moves. The upper mold base 3 continues to be rotated until the upper mold bin 5 and the lower mold bin 4 are completely closed. At this time, the sealing ring 9 is accurately inserted into the sealing groove 8 to form a good sealing structure, creating a sealed mold space for the subsequent processing of the rotationally molded sphere to prevent raw material leakage.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
