Description

Technical Field

[0001] The utility model relates to the field of plastic particle processing equipment, in particular to plastic particle feeding equipment. Background Art

[0002] Plastic pellets, commonly known as plastic granules, are the raw materials used to store, transport, and process plastics in semi-finished form. The upstream raw material for plastic pellets is petroleum, and they primarily exist in the form of semi-finished plastics, making them easier to store, transport, and process.

[0003] Plastic particles can be divided into thermoplastic plastic particles and thermosetting plastic particles according to their changes when heated. Thermoplastic plastics remain plastic after repeated heating and cooling, but thermosetting plastic particles lose their plasticity once they are heated, cooled and solidified. The plastic particles commonly used in life are thermoplastic plastic particles, such as polyethylene, polypropylene, polyvinyl chloride, etc.

[0004] Plastic particles have many properties, such as mechanical properties, heat resistance, low temperature resistance, aging resistance, flexibility resistance, electrochemical properties, etc., and the properties of different types of plastic particles are slightly different. For example, the biggest property of polyethylene plastic particles is low temperature resistance, the biggest property of PP plastic particles is high temperature resistance and flexibility resistance, and the biggest property of PVC is that it can be used for both soft and hard products.

[0005] Plastic particles are mainly used in films, packaging, plastic weaving, injection molding, pipe and profile products. For example, PE plastic particles are mostly used in the film field, such as agricultural film and packaging film, and are also used in water pipes, basins and buckets and other daily necessities; PP plastic particles are mostly used in home appliance injection molding products, and are also involved in packaging, pipes and other products. PVC plastic particles are mostly used in construction products such as profiles and plates, and are also used in raincoats, rain boots and other rain gear products.

[0006] Currently, plastic particles are generally cut into uniform spherical or cylindrical particles of exactly the same size during processing, with an outer diameter generally ranging from 1 to 5 cm, and the mass of each particle is almost the same.

[0007] Before processing plastic particles as raw materials, it is often necessary to first determine the mass or quantity of plastic particles to be fed in a single batch based on set parameters. However, there is currently no feeding equipment specifically for plastic particles. When feeding, workers are required to first weigh a certain mass or quantity of plastic particles and then feed them into the equipment for processing, making continuous operation difficult.

[0010] A first box cover is provided on the top of the first box body. Plastic particles can be added into the first box body after the first box cover is opened.

[0011] The bottom end of the second box body is hinged to a second box cover, and after the second box cover is opened, the accurately measured plastic particles in the second box body can be discharged for feeding.

[0012] Furthermore, the second box body is connected to the second box cover through an electric hinge, so that the second box body can be directly set above the feed port of the plastic particle processing equipment, and workers can remotely control the opening and closing of the second box cover to facilitate the discharge of feed.

[0013] A stirring mechanism is provided inside the first box body, which consists of a stirring shaft and stirring blades. Multiple stirring blades are installed on the stirring shaft. The stirring shaft is connected to a motor located outside the first box body. After the motor is started, it drives the stirring shaft to rotate.

[0015] The beneficial effects of the utility model are as follows: the plastic particle feeding equipment is provided with a first box body for storing the plastic particles to be counted. When performing precise feeding, the plastic particles in the first box body first fall into the guide tube in turn, and the motor drives the stripper plate to rotate in the guide tube through mechanical transmission. During the rotation process, each stripper plate strips a single plastic particle downward at a uniform speed in turn, and then the particle falls into the second box body for storage after being counted by the photoelectric counter; through program setting, when the photoelectric counter reaches the set value, the motor stops working, and the stripper plate will block the plastic particles from falling. At this time, the plastic particles in the second box body reach the expected value, and then the second box cover can be opened to discharge the plastic particles in the second box body for feeding; the equipment can realize precise feeding of plastic particles and ensure that the number of plastic particles fed each time meets the set requirements.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Reference Figure 1-3The present embodiment provides a plastic particle feeding device, comprising a first box body 1, a second box body 2 and a material guide pipe 3; a second box body 2 is provided below the first box body 1, a material guide pipe 3 is provided between the first box body 1 and the second box body 2, the top end of the material guide pipe 3 is connected to the bottom of the first box body 1, and the bottom end of the material guide pipe 3 is connected to the top of the second box body 2; the diameter of the material guide pipe 3 is preferably slightly larger than the outer diameter of the plastic particles; an opening is provided on the left side of the middle part of the material guide pipe 3, and a material diverting mechanism is installed on the outside of the material guide pipe 3; a photoelectric counter 10 is provided at the bottom of the material guide pipe 3.

[0023] In this embodiment, the material-dispensing mechanism comprises a coupling 4, a shaft seat 5, a dispensing plate 6, a transmission rod 7, a motor 8, and a connecting rod 9. The middle portion of the coupling 4 is rotatably connected to one end of the shaft seat 5, the other end of which is bolted to the outer wall of the material guide tube 3. The front end of the coupling 4 is fixedly connected to four dispensing plates, and the rear end of the coupling 4 is fixedly connected to four transmission rods. The motor 8 is bolted to the bottom of the first housing 1, and the rotating shaft of the motor 8 is bolted to the connecting rod 9, which is in transmission connection with the transmission rod 7. The dispensing plate 6 can be rotated through the opening into the material guide tube 3. When the motor 8 is started, the connecting rod 9 rotates via the rotating shaft. This rotation of the connecting rod 9 rotates the transmission rod 7, which in turn rotates the coupling 4, which in turn rotates the dispensing plate 6. When the dispensing plate 6 extends into the material guide tube 3, it dispensing individual plastic particles downward.

[0024] In this embodiment, the top end of the first box body 1 is connected to the first box cover 11 via a buckle. After the first box cover 11 is opened, plastic particles can be added into the first box body 1.

[0025] In this embodiment, the bottom end of the second box body 2 is hinged to the second box cover 12 through an electric hinge. After the second box cover 12 is opened manually by remote control, the accurately measured plastic particles in the second box body 2 can be discharged for feeding.

[0026] In order to prevent multiple plastic particles from getting stuck at the top of the guide tube 3 and unable to fall, a stirring mechanism 13 is provided inside the first box body 1. The stirring mechanism 13 consists of a stirring shaft and stirring blades. Multiple stirring blades are installed on the stirring shaft. The stirring shaft is connected to a motor located outside the first box body. After the motor is started, it drives the stirring shaft to rotate. The stirring shaft drives the stirring blades to stir the plastic particles in the first box body 1, causing the plastic particles to fall into the guide tube 3.

[0027] In this embodiment, an electric control panel 14 is installed on the outer wall of the guide tube 3. The electric control panel 14 is electrically connected to the photoelectric counter 10 and the motor 8 respectively. The counting results of the photoelectric counter 10 can be controlled and viewed through the electric control panel 14, and the speed of the motor 8 can be controlled.

[0028] The working principle of this equipment is: plastic particles are first poured into the first box body 1 for storage. When precise feeding is performed, the stirring mechanism 13 is started, causing the plastic particles in the first box body 1 to fall into the guide tube 3 in turn. The motor 8 drives the diverter plate 6 to rotate in the guide tube 3 through mechanical transmission. During the rotation process, each diverter plate 6 diverts a single plastic particle downward at a uniform speed in turn, and then falls into the second box body 2 for storage after being counted by the photoelectric counter 10; each diverter plate 6 diverts one plastic particle at a time, so that each plastic particle passes through the photoelectric counter 10 individually, greatly reducing the probability of counting errors.

[0029] It can be set through the program. When the photoelectric counter 10 reaches the set value, the motor 8 stops working. At this time, the material plate 6 will block the plastic particles from falling. At this time, the plastic particles in the second box body 2 reach the expected value, and then the second box cover 12 can be opened to discharge the plastic particles in the second box body 2.

The technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of the present invention and are not limitations of the present invention. The present invention is described in detail with reference to the preferred implementation methods. Ordinary technicians in this field should understand that the changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention and should also fall within the scope of protection of the claims of the present invention.
