Description

Technical Field

[0001] The utility model relates to the technical field of protective film production, and particularly relates to a quantitative feeder for protective film production. Background Art

[0002] A protective film is a transparent material with multiple functions, usually used to protect the surface of an object and reduce wear and scratches of the article. During the production process of the protective film, it is necessary to accurately control the weights of various materials that make up the protective film.

[0003] According to "A Quantitative Feeder for Protective Film Production" with the Chinese patent publication number CN117698003A, it mainly describes that the rotation of a motor drives the rotation of a rotating shaft, thereby controlling the rotation of a circular baffle on the rotating shaft, and further controlling the position of the protrusions on the circular baffle to achieve the controlled feeding of materials, effectively preventing the phenomenon of material blockage caused by excessive material feeding. And a material detection sensor is installed at the bottom of the circular feeding trough. When the material in the circular feeding trough is insufficient, by controlling the feeding controller, the material is sucked out of the storage tank through the suction pipe, and the circular feeding trough is replenished with materials through the discharge pipe and the feeding pipe, so as to achieve the precise control of materials. This invention can precisely control the materials, will not cause the phenomenon of empty materials or excessive materials resulting in blockage, and is beneficial to the supply of materials. When using the suction pipe to adsorb the protective film material, some of the protective film raw materials are adsorbed due to the suction force, resulting in inaccurate subsequent quantification.

[0004] Therefore, a quantitative feeder for protective film production is proposed to solve the problem that when using the suction pipe to adsorb the protective film material, some of the protective film raw materials are adsorbed due to the suction force, resulting in inaccurate subsequent quantification. Content of the Utility Model

Detailed Embodiment

[0016] The present utility model will be further described below with reference to the drawings.

[0017] Please refer to Figures 1-3 A metering feeder for producing a protective film shown in the figure, including a mixing tank 1, a heat pipe 2, a discharge pipe 4, a rotating rod 5 and a stirring rod 6. A driving motor is installed on the upper side of the mixing tank 1, and the rotating rod 5 and the stirring rod 6 are driven to rotate by the driving motor. One side of the upper end of the mixing tank 1 is fixedly connected with a metering cylinder 3. The raw materials of the protective film are put into the placing cylinder 13 from the metering cylinder 3, and then weighed by the weighing device 10. A guiding cover 7 is fixedly connected to the upper side inside the metering cylinder 3. A driving motor is fixedly connected to one side of the metering cylinder 3, and the output end of the driving motor is fixedly connected with a rotating rod 8. A support plate 9 is fixedly connected to the rotating rod 8. The upper end of the support plate 9 is in contact with the weighing device 10. The weighing device 10 is an electronic scale, a weighing device integrating sensor technology, electronic technology and computer technology. A cushion plate 12 is in contact with the weighing device 10. A placing cylinder 13 is welded to the upper end of the cushion plate 12. The cushion plate 12 cooperates with the placing cylinder 13 and can remain stable under the limit of the clamping strip 11 when the support plate 9 is turned over. A frustum 15 is fixedly connected inside the mixing tank 1. The frustum 15 is used to receive the falling materials and grind the raw materials of the protective film into fine particles, so as to facilitate passing through the conical groove 16 and the leakage groove 17, and thus facilitate hot melting to form a molten liquid. A conical groove 16 is opened at the upper end of the frustum 15, and a leakage groove 17 is opened at the lowest point of the conical groove 16 where the frustum 15 is located. A grinding block 18 is fixedly connected to the rotating rod 5, and the grinding block 18 corresponds to the conical groove 16.

[0018] Among them, a clamping strip 11 is clamped on the cushion plate 12. The clamping strip 11 is fixedly connected to the four sides of the upper end of the support plate 9. By setting the clamping strip 11 and the cushion plate 12, the function of limiting the placing cylinder 13 is achieved.

[0019] Among them, a limiting rod 14 is fixedly connected to the support plate 9. The limiting rod 14 is fixedly connected to the side of the clamping strip 11 close to the cushion plate 12. The clamping strip 11 is in an L-shaped structure. By setting the limiting rod 14, the stability of the placing cylinder 13 is improved.

[0020] Among them, the upper side of the frustum 15 corresponds to a scraper 19. The scraper 19 is fixedly connected to the two sides of the grinding block 18 that are far away from each other. By setting the scraper 19, the materials can be pushed into the bottom side of the mixing tank 1.

[0021] Among them, the frustum 15 is in contact with a brush 20. The brush 20 is fixedly connected to the bottom end of the scraper 19. By setting the brush 20, the materials can be further pushed.

[0022] Working principle: Various raw materials in the protective film enter the storage cylinder 13 through the material guiding cover 7 respectively. At this time, the raw materials react on the weighing device 10 under the condition of gravity. Then, the driving motor on one side of the metering cylinder 3 drives the support plate 9 to turn over, and makes the weighing device 10 and the storage cylinder 13 turn over. At this time, the raw materials fall onto the frustum 15, and are pushed by the scraping plate 19 and the brush 20 and fall into the conical groove 16, and are ground by the grinding block 18 to form fine particles, so as to facilitate mixing.

[0023] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.

[0024] Other parts not described in detail in the present invention belong to the prior art, so they will not be elaborated here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
