Description

Technical Field

[0001] This utility model belongs to the field of plastic product manufacturing technology, specifically relating to an auxiliary device for feeding plastic granules. Background Technology

[0002] Plastic granule feeding auxiliary devices play a vital role in the plastics processing industry. They aim to improve production efficiency, ensure product quality, and reduce errors and contamination from manual operation. These devices are specifically designed to automate the transport of plastic granules from storage containers to processing equipment. Their main functions include automatic feeding, metering, and ensuring the stability and accuracy of the granules during transport. Screw feeders, in particular, use the rotation of screw blades to transport plastic granules from a lower to a higher position, making them suitable for vertical or inclined conveying scenarios.

[0003] Currently, in actual use, plastic pellet feeding auxiliary devices first require the plastic pellets to be fed into the hopper. Then, the plastic pellets are fed and lifted by a screw feeder so that they can be transported to subsequent processing equipment.

[0004] However, in practice, a common problem is the agglomeration of plastic granules. This agglomeration can be caused by improper storage conditions, adsorption between granules, or excessively high ambient humidity. When plastic granules agglomerate, they may not be able to pass through the conveying channel of the screw conveyor normally, causing blockages or poor conveying, thus affecting the continuous and uniform supply of plastic granules. This not only reduces production efficiency but may also lead to equipment malfunctions, thereby affecting the subsequent processing quality of the plastic granules and the stability of the overall production line. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary device for feeding plastic granules, aiming to solve the problem that when plastic granules agglomerate, they may not be able to pass through the conveying channel of the screw conveyor normally, causing blockages or poor conveying, thus affecting the continuous and uniform supply of plastic granules. This not only reduces production efficiency but may also lead to equipment malfunctions, thereby affecting the subsequent processing quality of plastic granules and the stability of the overall production line.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic granule feeding auxiliary device, comprising a device support, a screw feeder, and a hopper. The screw feeder is mounted on the top of the device support, and a hopper is mounted on the surface of the screw feeder. A screen plate penetrates the surface of the hopper, and a guide rod penetrates the side surface of the screen plate. The guide rod is connected to the side surface of the hopper. A spring strip is connected between the hopper and the screen plate, and the spring strip is sleeved on the surface of the guide rod. A drive motor is mounted on the side surface of the hopper, and an eccentric wheel is connected to the output end of the drive motor.

[0007] As a plastic granule feeding auxiliary device of this utility model, preferably, the screen plate and the guide rod form a limiting structure, and the screen plate and the hopper are slidably connected.

[0008] As a plastic granule feeding auxiliary device of this utility model, preferably, the screen plate forms an elastic telescopic structure with the hopper through the spring strip.

[0009] As a plastic granule feeding auxiliary device of this utility model, preferably, a rotating shaft is installed on the surface of the device support, a support arm is connected to the side surface of the rotating shaft, an internally threaded tube is connected through the surface of the support arm, a threaded rod is connected through the inside of the internally threaded tube, a turntable is connected to the top of the threaded rod, a bearing is connected to the bottom of the threaded rod, the bearing is fitted and installed on the upper surface of the support, and a spring is connected to the surface of the support arm.

[0010] In order to adjust the position of the support arm, as a plastic granule feeding auxiliary device of this utility model, preferably, the rotating shaft and the support arm are symmetrically arranged in two sets on both sides of the device support, and the support arm forms a rotating structure with the device support through the rotating shaft.

[0011] In order to adjust the height of the support, as an auxiliary device for feeding plastic granules according to this utility model, preferably, the internal threaded tube and the threaded rod are threadedly connected, and the threaded rod forms a rotating structure with the support through a bearing.

[0012] In order to fix the outrigger when it is not in use, as a plastic granule feeding auxiliary device of this utility model, the spring is preferably made of beryllium copper.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the drive motor can drive the eccentric wheel to rotate during operation. The rotation of the eccentric wheel causes the screen plate to vibrate, which allows the plastic particles to be screened through the screen plate. This can remove the agglomerated plastic particles, thus preventing the agglomerated plastic particles from being unable to pass through the conveying channel of the screw feeder, causing blockage or poor conveying, which would affect the continuous and uniform supply of plastic particles.

[0015] In this invention, the support arm can rotate 90° to rotate the turntable. When the turntable drives the threaded rod to rotate inside the internal threaded tube, it can move downward. When the threaded rod moves downward, it can drive the support to move downward through the bearing. When the support moves downward to the ground, it can support the device bracket, thereby improving the stability of the feeding device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5The present invention provides the following technical solution: a plastic granule feeding auxiliary device, including a device support 1, a screw feeder 2 and a hopper 3. The screw feeder 2 is installed on the top of the device support 1, the hopper 3 is installed on the surface of the screw feeder 2, a screen plate 4 passes through the surface of the hopper 3, a guide rod 5 passes through the side surface of the screen plate 4, the guide rod 5 is connected to the side surface of the hopper 3, a spring strip 6 is connected between the hopper 3 and the screen plate 4, the spring strip 6 is sleeved on the surface of the guide rod 5, a drive motor 7 is installed on the side surface of the hopper 3, and an eccentric wheel 8 is connected to the output end of the drive motor 7.

[0025] First, plastic granules are added into the inside of hopper 3. Then, the plastic granules inside hopper 3 leak into the inside of screw feeder 2. The screw feeder 2 feeds and lifts the plastic granules, and then the plastic granules can be discharged from the storage cylinder of screw feeder 2.

[0026] Preferably, the screen plate 4 and the guide rod 5 form a limiting structure, and the screen plate 4 and the hopper 3 are slidably connected;

[0027] In practical use, when the screen plate 4 is subjected to force, it can move laterally on the inner wall of the hopper 3, which can restrict the movement direction of the screen plate 4.

[0028] Preferably, the sieve plate 4 forms an elastic telescopic structure with the hopper 3 via the spring strip 6;

[0029] In practical use, when the sieve plate 4 moves laterally, it can cause the spring strip 6 to deform. When the sieve plate 4 is subjected to force, the spring strip 6 recovers its deformation through its own elasticity.

[0030] Preferably: A rotating shaft 9 is mounted on the surface of the device support 1, a support arm 10 is connected to the side surface of the rotating shaft 9, an internally threaded tube 11 is connected through the surface of the support arm 10, a threaded rod 12 is connected through the inside of the internally threaded tube 11, a turntable 13 is connected to the top of the threaded rod 12, a bearing 14 is connected to the bottom of the threaded rod 12, the bearing 14 is fitted and installed on the upper surface of the support 15, and a spring piece 16 is connected to the surface of the support arm 10.

[0031] It should be noted that the support structure includes a rotating shaft 9, a support arm 10, an internally threaded pipe 11, a threaded rod 12, a turntable 13, a bearing 14, a support 15, and a spring piece 16. The support structure can support the device bracket 1, thereby improving the stability of the feeding device.

[0032] Preferably, two sets of rotating shafts 9 and support arms 10 are symmetrically arranged on both sides of the device support 1, and the support arms 10 form a rotating structure with the device support 1 through the rotating shafts 9;

[0033] In actual use, when the support arm 10 is subjected to force, it can be rotated through the pivot 9, which makes it easy to unfold the support arm 10.

[0034] Preferably, the internally threaded tube 11 and the threaded rod 12 are connected by a thread, and the threaded rod 12 forms a rotating structure with the support 15 through the bearing 14;

[0035] In practical use, when the turntable 13 drives the threaded rod 12 to rotate inside the internal threaded tube 11, it can move downward. When the threaded rod 12 moves downward, it can drive the support 15 to move downward through the bearing 14. When the support 15 moves to the ground, it can support the device.

[0036] Preferred material: shrapnel 16 is made of beryllium copper;

[0037] In actual use, when the spring 16 is locked inside the device bracket 1, the position of the support arm 10 can be fixed by the spring 16.

[0038] The working principle of this utility model in specific use is as follows: When using this plastic granule feeding auxiliary device, first pull the spring 16 to bend it upwards, then pull the support arm 10. After the support arm 10 rotates 90°, the turntable 13 can be rotated. When the turntable 13 rotates, it can drive the threaded rod 12 to rotate. When the threaded rod 12 rotates inside the internal threaded tube 11, it can move downwards. When the threaded rod 12 moves downwards, it can drive the support 15 to move downwards through the bearing 14. When the support 15 moves downwards to the ground, the device bracket 1 can be supported by the support 15, the threaded rod 12, the internal threaded tube 11 and the support arm 10, thereby ensuring the stability of the feeding device during use.

[0039] Next, plastic granules can be fed into the surface of the screen plate 4 in the hopper 3. Then, the drive motor 7 can be run. When the drive motor 7 runs, it can drive the eccentric wheel 8 to rotate. The long end of the eccentric wheel 8 can squeeze the screen plate 4. When the screen plate 4 is squeezed, it can slide on the surface of the guide rod 5 and pull the spring strip 6 to deform. After the squeezing force of the eccentric wheel 8 is removed, the elastic force of the spring strip 6 can drive the screen plate 4 to return to its original position. In this way, the rotation of the eccentric wheel 8 can make the screen plate 4 vibrate, so that the plastic granules can be screened through the screen plate 4, thereby screening out the agglomerated plastic granules.

[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.
