Description

Technical Field

[0001] The utility model relates to the field of plastic product production devices, in particular to a centralized feeding device for producing plastic straws. Background Art

[0002] A straw is a cylindrical, hollow plastic product. Its main function is to be used for drinking beverages from cups. In the production process of plastic straws, raw material particles, such as PP (polypropylene) and PE (polyethylene) particles, need to be fed into the equipment. The feeding is generally done through a vacuum suction machine, which feeds a variety of materials into the molding and processing equipment.

[0003] After searching, Chinese patent announcement number: CN219235822U discloses a centralized feeding device for PVC particles, which can dry PVC particles by hot air. At the same time, the PVC particles are stirred so that the dust attached to the PVC particles is easier to fall off and flow upward under the drive of the hot air, thereby drying the PVC particles and removing internal impurities. After drying, the dried PVC particles can be cooled by air flow, which is beneficial for subsequent use.

[0004] However, in actual use, the above-mentioned centralized feeding device may feed multiple materials into one molding processing equipment. When the multiple materials enter the molding processing equipment together, they are restricted by the feeding pipe and the feeding direction, which will cause a clear distinction between the multiple materials. As a result, a lot of time is required to evenly mix these materials in the subsequent processing process, which affects the processing efficiency. Therefore, a centralized feeding device for plastic straw production is proposed to solve the above problem. Utility Model Content

[0025] 1. In the utility model, a rotational force can be applied to various materials entering the hopper through the premixing assembly, so that the various materials can be rotated and dispersed to fall into the hopper for centralized feeding, thereby shortening the mixing time of subsequent materials entering the processing equipment and improving the processing efficiency. The coordination of the fixed rod, the conical dividing column and the dividing plate can prevent the materials from falling directly through the center of the mixing hopper and affecting the premix effect.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1 The utility model provides an embodiment: a centralized feeding device for producing plastic straws, including a hopper 1, a feeding pipe 2 is fixedly connected to the top of the hopper 1, a collecting pipe 3 is fixedly connected to the upper end of the feeding pipe 2, and a plurality of materials can be transported from a plurality of storage containers to the inside of the hopper 1 through the arranged collecting pipe 3, and then enter into a processing device through the bottom end of the hopper 1, and a premixing component is arranged inside the hopper 1.

[0036] Reference Figure 2-Figure 4 The premixing assembly includes: a fixed plate 401, an annular gear plate 404 and a fixed rod 408. The fixed plate 401 is fixedly connected to the left side surface of the hopper 1. The upper surface of the fixed plate 401 is fixedly connected to a motor 402. The top output end of the motor 402 is fixedly connected to a gear 403. When the motor 402 is started, the gear 403 can be driven to rotate. The annular gear plate 404 is arranged inside the hopper 1. A through groove is provided on the left side surface of the hopper 1. The right end of the gear 403 is meshed with the tooth surface of the annular gear plate 404 through the through groove. When the gear 403 rotates, the annular gear plate 404 can be driven to rotate synchronously.

[0037] A mixing bucket 405 is fixedly connected to the center of the bottom surface of the annular toothed plate 404. When the material falls into the rotating mixing bucket 405 and contacts the inner wall of the mixing bucket 405, the mixing bucket 405 will exert a rotational force on the material, so that the material is thrown out into the hopper 1 at will, thereby allowing a variety of materials to be mixed, thereby reducing the subsequent mixing processing time. The inner wall surface of the mixing bucket 405 can be fixedly connected to a plurality of material retaining strips arranged in a ring structure, so that the material can be better rotated and dropped, further improving the premix effect. An annular slide bar 406 is fixedly connected to the upper surface of the annular toothed plate 404, and an annular slide groove 407 is provided on the internal top surface of the hopper 1. The annular slide bar 406 is slidably connected to the inside of the annular slide groove 407. Through the cooperation of the annular slide bar 406 and the annular slide groove 407, the annular toothed plate 404 can be supported and limited, so that the annular toothed plate 404 can move stably.

[0038] The fixing rod 408 is fixedly connected to the inside of the annular tooth plate 404, and the upper end of the fixing rod 408 is fixedly connected with a conical material dividing column 409. The size of the conical material dividing column 409 is adapted to the size of the bottom end of the mixing bucket 405. The conical material dividing column 409 can block the center of the mixing bucket 405 to prevent the material from being discharged directly through the center of the mixing bucket 405 without mixing, which affects the premixing effect. The top tip structure of the conical material dividing column 409 can prevent the material from being pushed on the top of the conical material dividing column 409. The left and right sides of the conical material dividing column 409 The surface is fixedly connected with a dividing plate 410, and the end of the dividing plate 410 away from the conical dividing column 409 is in contact with the inner wall of the feed pipe 2, and the top of the dividing plate 410 is arranged in a pointed structure. When the annular tooth plate 404 rotates, it can drive the dividing plate 410 to move synchronously. The rotating dividing plate 410 will beat the material discharged through the dividing plate 410, so that the material can obtain more rotational force and achieve better mixing. At the same time, the top tip setting of the dividing plate 410 can prevent the material from accumulating at the bottom of the dividing plate 410 and making it impossible to discharge the material.

[0039] Reference Figure 3-Figure 5 , an annular groove 501 is provided on the upper surface of the annular tooth plate 404, an elastic member 502 is fixedly connected to the inner bottom surface of the annular groove 501, an annular plate 503 is fixedly connected to the upper surface of the elastic member 502, a rubber ring 504 is fixedly connected to the upper surface of the annular plate 503, the outer wall surface of the rubber ring 504 fits with the inner part of the annular groove 501, in the initial state, the rubber ring 504 is slightly compressed, slightly deformed and fits tightly with the inner wall of the annular groove 501, the top of the rubber ring 504 is fixedly connected to an annular arc strip 505, the top of the annular arc strip 505 fits with the inner top surface of the hopper 1, in the initial state, the elastic member 502 generates elastic potential energy due to the compression state, and at this time ... The elastic member 502 will apply elastic potential energy to the annular arc strip 505 through the annular plate 503 and the rubber ring 504, so that the annular arc strip 505 fits tightly with the inner top surface of the hopper 1, and then the annular arc strip 505 can cooperate with the rubber ring 504 to seal the gap between the annular tooth plate 404 and the inner top surface of the hopper 1, so as to prevent the material from being stuck in the gap and hindering the rotation movement of the annular tooth plate 404, thereby affecting the pre-mixing effect of the material. The arc structure of the annular arc strip 505 reduces the contact area between the annular arc strip 505 and the inner top surface of the hopper 1 as much as possible, and only the contact between the line and the surface can be reduced to the greatest extent possible. The hindrance to the rotation of the annular tooth plate 404 can be reduced as much as possible.

[0040] Working principle: When materials from multiple places enter the feed pipe 2 through the collecting pipe 3 and fall into the hopper 1 for centralized feeding, the motor 402 can be started to drive the mixing bucket 405 and the dividing plate 410 to rotate synchronously, so that the mixing bucket 405 and the dividing plate 410 exert a rotational force on the materials falling downward, so that various materials are evenly dispersed and sprinkled into the hopper 1 for premixing, thereby reducing the mixing time of subsequent materials in the processing device and improving the processing efficiency. The conical dividing column 409 can prevent the material from being directly discharged through the center of the mixing bucket 405 and affecting the premixing effect. At the same time, the rubber ring 504 and the annular arc strip 505 will seal the gap between the annular tooth plate 404 and the top surface of the hopper 1 under the action of the elastic potential energy of the elastic member 502, so as to prevent the material from being stuck in the gap and hindering the operation of the premixing component.
