Description

Technical Field

[0001] The utility model relates to the field of machinery, and particularly to an anti-blocking feeding mechanism for TPU particle processing. Background Technique

[0002] During the processing of TPU particles, the feeding mechanism is the starting point of the entire production line, and its stability and reliability directly affect the normal progress of subsequent processes. Since TPU particles sometimes adhere together due to factors such as temperature, resulting in the particles becoming a mass and unable to be processed, most of the current feeding structures on the market use methods such as stirring to separate the agglomerated particles. This method has certain limitations. There are gaps between the stirring rods, so the agglomerated particles cannot be completely separated. In view of this, we propose an anti-blocking feeding mechanism for TPU particle processing. Content of the Utility Model

[0003] The main purpose of the utility model is to provide an anti-blocking feeding mechanism for TPU particle processing to solve the problems raised in the related technology.

[0004] To achieve the above object, according to one aspect of the utility model, an anti-blocking feeding mechanism for TPU particle processing is provided, including a feeding mechanism housing. A vibration assembly is arranged inside the feeding mechanism housing. The vibration assembly includes a plurality of screening plates arranged side by side up and down, a connecting rod for connecting the plurality of screening plates, and a vibration part for driving the screening plates to vibrate up and down. The vibration part drives the connecting rod and the screening plates on the connecting rod to vibrate up and down to prevent the TPU particles from caking and blocking.

[0005] Further, three groups of feeding ports are opened on the feeding mechanism housing, and a discharge port is opened below the feeding mechanism housing. A cross bracket is fixedly connected inside the feeding mechanism housing, and a spring is fixedly connected to the center of the cross bracket.

[0006] Further, the vibration part includes a primary power source, a cam is arranged at one end of the primary power source. The vibration assembly further includes a guide cylinder, a connecting rod is arranged inside the guide cylinder, and four groups of screening plates are fixedly connected to the connecting rod.

[0007] Further, the guide cylinder is of a hollow structure, and a limiting hole is opened below. The radius of the limiting hole is the same as the radius of the connecting rod, for the connecting rod to move up and down. A connecting rod limiting block is fixedly connected above the connecting rod, and the radius of the connecting rod limiting block is greater than the radius of the limiting hole, for fixing the connecting rod so that it will not fall off from the guide cylinder.

[0008] Further, a hole is opened on the side of the guide cylinder for the output end of the primary power source to extend in and connect to drive the cam.

[0009] Furthermore, a number of holes are provided in the four groups of the screening plates for particles to pass through.

[0010] Furthermore, the upper end of the spring is fixedly connected to the bottom of the connecting rod to limit the connecting rod and apply elastic force to it.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, a motor is arranged to drive a cam to press the screening plate and apply pressure to the spring at the same time. The spring below compresses and rebounds to push the screening plate to rise. The screening plate drives the agglomerated particles to vibrate up and down, separating the agglomerated particles into small particles. The small particles can pass through the holes in the screening plate and be screened into the discharge port, solving the problem that most of the feeding structures on the current market cannot separate the agglomerated particles bonded together; at the same time, multiple groups of feeding ports are provided, and when adding TPU particles, each feeding port can add particles together to make the particle distribution more uniform.

[0020] In order to further elaborate on the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manners, structures, features and their effects of the utility model as follows.

[0021] Please refer to Figures 1 - 4As shown in the figure, the purpose of this embodiment is to provide an anti-blocking feeding mechanism for TPU granule processing, which includes a feeding mechanism housing 1. Inside the feeding mechanism housing 1, there is a vibration assembly 2. The vibration assembly 2 includes a plurality of screening plates 25 arranged side by side up and down, a connecting rod 24 for connecting the plurality of screening plates 25, and a vibration part for driving the screening plates 25 to vibrate up and down. The vibration part drives the connecting rod 24 and the screening plates 25 on the connecting rod 24 to vibrate up and down, preventing the TPU granules from caking and blocking.

[0022] It should be noted that: The primary power source is preferably a motor 21, and the motor 21 is fixed on the inner wall of the feeding mechanism housing 1.

[0023] There are three groups of feeding ports 11 opened on the feeding mechanism housing 1, and a discharging port 12 is opened below the feeding mechanism housing 1. Inside the feeding mechanism housing 1, there is a cross support 13 fixedly connected, and a spring 14 is fixedly connected at the center of the cross support 13.

[0024] The vibration part includes a primary power source. One end of the primary power source is provided with a cam 22. The vibration assembly 2 further includes a guide cylinder 23. Inside the guide cylinder 23, there is a connecting rod 24, and four groups of screening plates 25 are fixedly connected to the connecting rod 24.

[0025] It should be added that: The output end of the motor 21 passes through the feeding mechanism housing on one side of the guide cylinder 23 and is fixedly connected to the cam 22.

[0026] The guide cylinder 23 is of a hollow structure, and a limiting hole 231 is opened below. The radius of the limiting hole 231 is the same as the radius of the connecting rod 24, for the connecting rod 24 to move up and down under the limitation of the limiting hole 231. A connecting rod limiting block 241 is fixedly connected above the connecting rod 24. The radius of the connecting rod limiting block 241 is larger than the radius of the limiting hole 231 and is the same as the inner radius of the guide cylinder 23, for fixing and guiding the connecting rod 24 so that it will not fall off from the guide cylinder 23.

[0027] A hole is opened on the side of the guide cylinder 23 for the output end of the primary power source to extend in and connect to drive the cam 22.

[0028] A number of holes are opened on the four groups of screening plates 25 for the granules to pass through.

[0029] The upper end of the spring 14 is fixedly connected to the bottom of the connecting rod 24 to limit the connecting rod 24 and apply elastic force.

[0030] When the utility model is in specific use, pour TPU particles from the three groups of feeding ports 11. After the particles reach the screening plate 25, the motor 21 in the vibration assembly 2 rotates to drive the cam 22 to rotate. Subsequently, under the current action of the guiding cylinder 23, the cam 22 squeezes the connecting rod limiting block 241 to drive the connecting rod 24 to move downward under the limitation of the limiting hole 231. The connecting rod 24 drives the four groups of screening plates 25 to move downward. At the same time, the connecting rod 24 presses the spring 14 at its bottom downward. Since the bottom of the spring 14 is fixed on the cross bracket 13, the spring 14 will contract. When the cam 22 rotates to the other end, the spring 14 rebounds to make the device move upward. The generated vibration will shake off the agglomerated particles that are bonded together. Subsequently, the shaken-off agglomerated particles will leak through the holes in the screening plate 25 until they reach the discharge port 12.

[0031] The above is only the preferred embodiment of the utility model, and it is not a limitation to the utility model in any form. Although the utility model has been disclosed as above with the preferred embodiment, it is not intended to limit the utility model. Any person skilled in the art can make some changes or modifications to it as equivalent embodiments within the scope of the technical solution of the utility model. However, as long as it does not depart from the content of the technical solution of the utility model, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model still fall within the scope of the technical solution of the utility model.
