Description

Technical Field

[0001] This utility model relates to the field of plastic granule processing, and in particular to a plastic granule feeding device. Background Technology

[0002] Plastics generally refer to materials and products made primarily of resin that possess plasticity. Under certain conditions, they are plasticized and molded, and the final product retains its shape. There are many types, such as bakelite and plexiglass. Plastics possess excellent properties such as being lightweight, insulating, and acid-resistant. They are widely used in manufacturing and consumer goods, and can replace metals and wood.

[0003] The existing patent with publication number CN222373599U discloses a plastic granule feeding machine, including a fixed plate and a fixed frame, a conveyor belt, a pouring plate, a spreading section, and a feeding section. The fixed plate is disposed on one side of the fixed frame; the conveyor belt is disposed between the fixed frames, and side baffles are provided on both sides of the conveyor belt.

[0004] The aforementioned device features an inclined pouring plate at one end of the conveyor belt, with multiple staggered fixed posts on the plate. These posts create gaps between the posts, allowing the particles to slide down the conveyor belt evenly and spread out. This facilitates better contact between the magnetic conveyor belt and the metal. When the particles reach the exhaust fan, they are extracted and directly fed into the feed box. Heavier materials enter the feed bin directly, while metal scraps fall into the scrap collection bin, increasing sorting efficiency and improving feeding performance. However, before feeding the plastic particles, this device cannot guarantee that all particles are of uniform size. Larger particles can negatively impact the subsequent melting speed and efficiency.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] In the attached diagram, all identical reference numerals refer to the same components.

[0023] like Figure 1-3 As shown, this utility model provides a plastic granule feeding device, comprising:

[0024] The base plate 1 has two sets of conveying components 2 on its top and a screening component 3 in the middle of its top. The screening box 301 is installed on the top of the base plate 1 by a bracket.

[0025] Example 1

[0026] In this embodiment, the conveying assembly 2 includes a conveyor belt 201, a drive shaft 202, a driven shaft 203, a first mounting base 204, a second mounting base 205, a collection box 206, a feeding part 207, and a motor. The drive shaft 202 is mounted on the top of the first mounting base 204, and the driven shaft 203 is mounted on the top of the second mounting base 205. The motor is mounted on the outside of the first mounting base 204, and the rotating shaft of the motor is connected to the drive shaft 202. The conveyor belt 201 is sleeved on the outside of the drive shaft 202 and the driven shaft 203, and the drive shaft 202 is connected to the driven shaft 203 through the conveyor belt 201.

[0027] Furthermore, a material collection box 206 is provided inside the second mounting base 205 on one side, and a feeding part 207 is installed on one side of the first mounting base 204 on the other side.

[0028] Specifically, the drive shaft 202 is driven by a motor, and the conveyor belt 201 and driven shaft 203 work together to transport the plastic granules. The screened plastic granules are fed into the plastic granule melting equipment through the feeding section 207, and larger plastic granules are collected in the collection box 206 for subsequent processing.

[0029] Example 2

[0030] In this embodiment, the screening assembly 3 includes a screening box 301, a feed pipe 302, a screening plate 303, a vibrator 304, a first guide frame 305, a second guide frame 306, and a guide plate 307. The feed pipe 302 is provided on one side of the top of the screening box 301. The screening plate 303 is installed at an incline inside the screening box 301. The screening plate 303 is inclined downward toward the collection box 206. The guide plate 307 is installed at an incline inside the screening box 301. The guide plate 307 is inclined downward toward the feeding part 207.

[0031] Furthermore, the screening box 301 has through holes on both sides, which correspond to the screening plate 303 and the guide plate 307 respectively. A vibrator 304 is installed on one side of the bottom of the screening plate 303.

[0032] Furthermore, guide frames 1 305 and 2 306 are respectively installed on both sides of the screening box 301. Guide frames 1 305 and 2 306 correspond to the through holes on both sides. The bottom ends of guide frames 1 305 and 2 306 are inclined towards the conveyor belts 201 on both sides and extend to the top of the conveyor belts 201.

[0033] Specifically, the vibrator 304 drives the screening plate 303 to vibrate, which performs screening of plastic granules. Plastic granules that meet the specifications fall onto the guide plate 307, and then are guided to the top of the conveyor belt 201 through the first guide frame 305. They are then conveyed to the feeding section 207 by the conveyor belt 201. Larger plastic granules on the screening plate 303 are guided to the top of the other side of the conveyor belt 201 through the second guide frame 306, and then conveyed to the collection box 206 by the conveyor belt 201 for centralized collection.

[0034] Working principle:

[0035] When in use, connect the device to an external power supply and controller.

[0036] Then the motor is started, and its rotating shaft drives the drive shaft 202 to rotate. Since the drive shaft 202 and the driven shaft 203 are externally fitted with conveyor belts 201, the drive shaft 202 is connected to the driven shaft 203 through the conveyor belts 201. Therefore, the driven shaft 203 rotates accordingly, and the two conveyor belts 201 begin to circulate. At the same time, the vibrator 304 is started, putting it into working condition.

[0037] Feeding and preliminary screening: Plastic granules are poured into the screening box 301 through the feed pipe 302. The plastic granules entering the screening box 301 fall onto the screening plate 303. Since the vibrator 304 is installed on the bottom side of the screening plate 303, the vibrator 304 generates vibration when it is working, which drives the screening plate 303 to vibrate, thus screening the plastic granules.

[0038] Qualified Particle Guiding and Conveying: After screening, plastic particles that meet the specifications slide down the inclined screen plate 303, which is tilted downwards towards the feeding section 207. They pass through the through-holes on one side of the screen box 301 corresponding to the screen plate 303 and enter the guide frame 305. The bottom end of the guide frame 305 is tilted towards the conveyor belt 201 on one side and extends above it. Qualified plastic particles slide down the guide frame 305 onto the conveyor belt 201 on that side. The conveyor belt 201 operates, conveying the qualified plastic particles to the feeding section 207, and then through the feeding section 207, the plastic particles are introduced into the melting equipment, thus completing the feeding operation.

[0039] Non-conforming particle guidance and collection: Larger plastic particles that do not meet specifications remain on the sieve plate 303. With vibration, they gradually move to the other side and enter the guide frame 306 through the through-holes on the other side of the sieve box 301 corresponding to the sieve plate 303. The bottom end of the guide frame 306 is inclined towards the conveyor belt 201 on the other side and extends above it. Non-conforming plastic particles slide down onto the conveyor belt 201 on that side through the guide frame 306. The operation of the conveyor belt 201 on that side transports the non-conforming plastic particles to the collection box 206 for collection, so that they can be further processed or recycled.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
