Description

Technical Field

[0001] This utility model relates to the technical field of rubber particle screening equipment, specifically a vibration-type particle screening device for rubber thermoplastics. Background Technology

[0002] Thermoplastic processing of rubber is a processing method that uses specific techniques to plasticize and shape rubber materials under heating conditions, allowing them to retain their shape after cooling. This processing method is mainly applicable to thermoplastic rubber materials.

[0003] The raw material for rubber thermoplastic processing is usually rubber particles. Before use, rubber particles typically need to be screened. Screening separates rubber particles of different sizes, ensuring the quality and consistency of the plastic products. Screening not only removes impurities but also improves the flowability of the rubber particles, facilitating subsequent processing and use.

[0004] Current screening devices have a fixed structure during use, which makes the discharge position fixed. If the screening work is divided into multiple grades, it is inconvenient to receive materials for each grade. The discharge positions can easily obstruct each other, which will affect the efficiency of the screening device. In some screening devices, particles tend to accumulate during operation, resulting in insufficient screening. Therefore, we propose a vibrating particle screening device for rubber thermoplastics to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a vibratory particle screening device for rubber thermoplastics, in order to solve the problems mentioned in the background art, such as the inconvenience of material discharge and insufficient screening of current screening devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibrating particle screening device for rubber thermoplastics, comprising a device base, universal wheels mounted on the lower side of the device base, a lower fixing plate fixed on the upper side of the device base, a spring fixed on the lower fixing plate, an upper fixing plate fixedly connected to the upper end of the spring, a receiving hopper fixedly mounted on the upper side of the upper fixing plate by a locking assembly, a filter bucket fixedly mounted on the upper side of the receiving hopper by a locking assembly, a discharge port provided on the side of both the receiving hopper and the filter bucket, and a feeding hopper fixedly mounted on the upper side of the filter bucket by a locking assembly.

[0007] Preferably, the casters are self-locking casters, and four casters are symmetrically distributed at the center of the lower side of the device base.

[0008] Preferably, the device base and the lower fixing plate are fixedly connected by bolts.

[0009] Preferably, two vibration motors are symmetrically installed at the center of the upper fixing plate.

[0010] Preferably, the locking assembly includes a left collar, a right collar, a connecting hinge, a fixing joint, and a fixing bolt.

[0011] Preferably, the inner sides of the left and right collars are both concave structures, and the connection between the receiving hopper and the filter hopper, the connection between the filter hopper and the feed hopper, and the connection between the receiving hopper and the upper fixed plate are all fixed by the left and right collars engaging.

[0012] Preferably, a filter screen and baffles are fixed inside the filter bucket, and the baffles are symmetrically distributed on the upper side of the filter screen.

[0013] Preferably, the upper end of the feed hopper is funnel-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The vibrating screening particle device for rubber thermoplastic is equipped with multi-layer filter buckets and receiving buckets. The installation and fixing of the filter buckets and receiving buckets are completed by locking components, which not only facilitates the quick disassembly and assembly of the filter buckets and receiving buckets, but also facilitates the adjustment of the position of the discharge port on the filter buckets and receiving buckets, so that the discharge position of each discharge port will not affect each other, and ensures the normal operation of the discharge work.

[0016] (2) A filter screen and baffles are installed in the filter bucket. The filter screen ensures the normal operation of the screening work. The baffles can make the material vibrate differently when it approaches the baffles during the vibration screening process, thus making it easier to break up the material during the vibration process and ensuring the quality of the material screening work.

[0024] 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.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a vibrating particle screening device for rubber thermoplastics, including a device base 1, with casters 2 installed on the lower side of the device base 1. The casters 2 are self-locking casters, and four casters 2 are symmetrically distributed at the center of the lower side of the device base 1, which facilitates the movement of the device and ensures the stability of the device, thereby enabling the device to work normally.

[0026] A lower fixing plate 3 is fixed on the upper side of the device base 1. The device base 1 and the lower fixing plate 3 are fixedly connected by bolts, which facilitates the disassembly and separation of the device base 1 and facilitates the maintenance of the device. A spring 4 is fixed on the lower fixing plate 3. An upper fixing plate 10 is fixedly connected to the upper end of the spring 4. Two vibration motors 11 are symmetrically installed in the middle of the upper fixing plate 10 to ensure the uniformity of the vibration effect and thus improve the efficiency of the screening work.

[0027] A receiving hopper 5 is fixedly installed on the upper side of the upper fixed plate 10 by a locking component 9. A filter hopper 6 is fixedly installed on the upper side of the receiving hopper 5 by a locking component 9. Both the receiving hopper 5 and the filter hopper 6 have discharge ports 7 on their sides. A feeding hopper 8 is fixedly installed on the upper side of the filter hopper 6 by a locking component 9.

[0028] Furthermore, the locking assembly 9 includes a left collar 901, a right collar 902, a connecting hinge 903, a fixing joint 904, and a fixing bolt 905. One end of the left collar 901 and the right collar 902 are movably connected by the connecting hinge 903, allowing the left collar 901 and the right collar 902 to open and close. The other end of the left collar 901 and the right collar 902 is provided with a fixing joint 904, which is fixed by the fixing bolt 905 and the nut, facilitating the fixing of the left collar 901 and the right collar 902.

[0029] Furthermore, the inner sides of both the left collar 901 and the right collar 902 are concave structures. The connection between the receiving hopper 5 and the filter hopper 6, the connection between the filter hopper 6 and the feed hopper 8, and the connection between the receiving hopper 5 and the upper fixing plate 10 are all engaged and fixed by the left collar 901 and the right collar 902, ensuring the stable installation of the receiving hopper 5, the filter hopper 6, and the feed hopper 8, and also improving the efficiency of disassembly and assembly.

[0030] Furthermore, a filter screen 12 and baffles 13 are fixed inside the filter hopper 6. The baffles 13 are symmetrically distributed on the upper side of the filter screen 12, which facilitates the guidance and dispersion of the vibrating material, so that the material is concentrated in the middle of the filter screen 12, effectively improving the sufficiency of vibration screening.

[0031] Furthermore, the upper end of the feed hopper 8 is funnel-shaped, which concentrates the material feeding at the center of the filter screen 12 on the filter hopper 6, thereby improving the vibration screening efficiency.

[0032] Working principle: When using this vibrating particle screening device for rubber thermoplastics, firstly, the lower edge of the receiving hopper 5 is engaged with the edge of the upper fixed plate 10 by locking the left collar 901 and the right collar 902 on the locking assembly 9, so that the receiving hopper 5 and the upper fixed plate 10 are fixed together. Then, according to the required screening level, a suitable number of filter hoppers 6 are selected and the filter hoppers 6 are stacked and fixed on the receiving hopper 5 by locking the assembly 9. Finally, the feed hopper 8 is fixed on the uppermost filter hopper 6 by locking the assembly 9, thus completing the preparation of the device.

[0033] Then, the vibration motor 11 on the upper fixed plate 10 is started. The vibration motor 11 causes the upper fixed plate 10 to vibrate. The upper fixed plate 10 is provided with springs 4 for support around its lower side to ensure that the upper fixed plate 10 can perform normal and efficient vibration work.

[0034] The vibration of the upper fixed plate 10 drives the receiving hopper 5 and the filter hopper 6 to vibrate synchronously. Then, the rubber particles to be screened are put into the feeding hopper 8. The rubber particles are filtered through the filter hoppers 6 at each level. The filter hopper 6 is equipped with a filter screen 12 and baffles 13. The filter screen 12 screens the rubber particles, while the baffles 13 guide and disperse the rubber particles during the vibration process to ensure the full screening of the rubber particles.

[0035] After screening, the rubber particles are finally discharged through each discharge port 7. Based on the number of receiving hoppers 5 and filter hoppers 6, the discharge ports 7 are distributed in appropriate positions around the perimeter to effectively avoid adverse effects between the discharge operations.

[0036] The above describes the working process of the device, and all content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0037] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
