Abstract
Description
Technical Field
[0001] This utility model relates to the field of resin filtration technology, and in particular to a multi-stage resin filter discharge device for sensor production. Background Technology
[0002] Resin generally refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid or semi-solid at room temperature, and sometimes can also be liquid. In a broad sense, any polymer compound that can be used as a raw material for processing plastic products is called resin.
[0003] In the prior art, Chinese patent document CN221656009U discloses a resin discharge and filtration mechanism, including a filter cylinder and a top cover. A servo motor is embedded in the center of the top of the top cover, and the power output end of the servo motor passes through the top cover and extends into the interior of the filter cylinder. During filtration, it can actively push the resin to move downwards, allowing the resin to flow quickly through the filter plate, greatly improving filtration efficiency. Furthermore, during the feeding process, it ensures that the resin is evenly distributed on the surface of the filter plate, preventing the resin from being pushed together and affecting the flow rate. However, in actual use, the above solution easily clogs the filter device with impurities and lacks effective cleaning and slag removal functions, leading to frequent equipment downtime for maintenance and affecting production continuity. Therefore, this utility model proposes a multi-stage resin filter discharger for sensor production to meet the need for automatic cleaning of the filter plate and removal of impurities during the resin filtration process. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a multi-stage resin filter discharge device for sensor production, so as to solve the problem that impurities easily clog the filter device.
[0005] To achieve the above objectives, this utility model provides a multi-stage resin filter discharge device for sensor production, comprising a support frame, a rotating shaft mounted on the support frame, a connecting rod disposed within the rotating shaft, a mounting bracket at one end of the rotating shaft, a first drive motor mounted on the mounting bracket, a transmission shaft disposed at the output end of the first drive motor, a mixing tank body connected to the other end of the transmission shaft, a cover plate mounted on the mixing tank body, a second drive motor disposed on the cover plate, multiple sets of filter plates disposed within the mixing tank body, filter plates having filter holes, and a scraping assembly disposed within the mixing tank body; the scraping assembly is used to scrape resin impurities within the mixing tank body.
[0006] Preferably, the scraping assembly includes a stirring shaft disposed at the output end of the second drive motor, a plurality of rotating rings are sleeved on the stirring shaft, a plurality of cleaning plates are disposed on the rotating rings, the cleaning plates are telescopic structures, a return spring is disposed inside the cleaning plates, the cleaning plates are inclined, and the bottom of the cleaning plates is in contact with the surface of the filter plate.
[0007] Preferably, a contact head is provided at the top of one end of the cleaning plate, and a collection plate is provided at the bottom of one end of the cleaning plate, the collection plate being scoop-shaped.
[0008] Preferably, the stirring shaft is provided with multiple sets of stirring blades, which are inclined and used to stir the resin raw materials in the stirring tank body.
[0009] Preferably, a heating chamber is provided inside the mixing tank.
[0010] Preferably, a discharge pipe is provided at the bottom of the mixing tank body. The discharge pipe is tapered, and the filter plate provided inside the discharge pipe changes with the diameter of the discharge pipe.
[0011] Preferably, the discharge pipe is provided with multiple sets of guide grooves, which are inclined and symmetrically distributed on the discharge pipe.
[0012] Preferably, the spring force of the return spring inside the cleaning plate normally keeps the cleaning plate away from the inner wall of the mixing tank body.
[0013] Preferably, a sliding groove is provided at one end of the guide groove, a lifting plate is slidably disposed in the sliding groove, a guide plate is provided at one end of the lifting plate, and the guide plate is inclined to one side.
[0014] Preferably, the contact head has an arc-shaped structure that bends to one side, and the contact head can contact the guide plate.
[0015] The beneficial effects of this utility model are:
[0016] 1. The first drive motor drives the mixing tank body to rotate via a transmission shaft, thereby stirring the resin inside the tank and enhancing the mixing uniformity. The mixing tank body is mounted on a mounting frame at one end via a rotating shaft, and connected to a connecting rod at the other end, ensuring the mixing tank remains stable during transmission. A heating chamber is provided inside the mixing tank body to heat the resin. By setting a heating chamber inside the mixing tank body, the temperature and fluidity of the resin are improved, facilitating continuous filtration and discharge. The second drive motor on the cover plate drives the scraping component to operate. During the stirring process, the scraping component scrapes away resin impurities on the filter plates, preventing filter pore blockage. Multiple sets of filter plates sequentially perform multi-stage filtration of the resin. The multiple sets of filter plates, together with the filter pores, form a multi-stage filtration structure, enabling step-by-step filtration of impurities of different sizes, improving filtration efficiency and resin purity. The overall structure is compact and highly integrated, suitable for the continuous processing needs of high-purity resin in sensor production.
[0017] 2. The second drive motor drives the stirring shaft to rotate. Multiple sets of stirring blades are installed on the stirring shaft, and these blades are angled to fully agitate the resin raw material during stirring, promoting uniform mixing and preventing localized sedimentation. Simultaneously, multiple rotating rings fitted onto the stirring shaft drive multiple cleaning plates to move synchronously during rotation. These cleaning plates are angled, with their bottoms adhering to the surface of the filter plate, thus scraping away attached impurities. This synchronous scraping action during stirring effectively prevents the filter plate surface from clogging due to impurity accumulation, improving filtration efficiency and continuous operation capability. The cleaning plates are equipped with return springs, allowing them to elastically return to their original position when not under stress, thus moving away from the inner wall of the mixing tank and avoiding unnecessary friction. The internal filter plates are arranged in stages along the diameter of the discharge pipe, achieving a multi-stage filtration effect and ultimately discharging pure resin raw material. This ensures stable output quality and meets the resin purity requirements for high-quality sensor production.
[0018] 3. The cleaning plate cleans impurities from the filter plate surface as it rotates. As the impurities approach the cleaning plate, it moves the cleaning plate, allowing the contact head to make contact with the guide plate. This enables mechanical linkage without an additional power source, thereby driving the automatic lifting of the lifting plate. This allows impurities to be discharged from the inside, assisting in the impurity discharge process during resin discharge. Attached Figure Description

[0029] like Figures 1-6As shown, a multi-stage resin filter discharge device for sensor production includes a support frame 1, a rotating shaft 2 mounted on the support frame 1, a connecting rod 3 disposed inside the rotating shaft 2, a mounting frame 4 disposed at one end of the rotating shaft 2, a first drive motor 6 mounted on the mounting frame 4, a transmission shaft 5 disposed at the output end of the first drive motor 6, and a mixing tank body 7 connected to the other end of the transmission shaft 5. A heating chamber is disposed inside the mixing tank body 7. The other side of the mixing tank body 7 is connected to the connecting rod 3. A cover plate 8 is disposed on the mixing tank body 7, a second drive motor 9 is disposed on the cover plate 8, multiple sets of filter plates 13 are disposed inside the mixing tank body 7, filter plates 13 have filter holes 14, and a scraping assembly is disposed inside the mixing tank body 7. The scraping assembly is used to scrape resin impurities inside the mixing tank body 7.
[0030] The first drive motor 6 drives the mixing tank body 7 to rotate via the transmission shaft 5, thereby stirring the resin inside the tank and enhancing the mixing uniformity. The mixing tank body 7 is mounted on the mounting bracket 4 at one end via the rotating shaft 2, and connected to the connecting rod 3 at the other end, so that the mixing tank can remain stable during transmission. A heating chamber is provided inside the mixing tank body 7 for heating the resin. By setting a heating chamber inside the mixing tank body 7, the temperature and fluidity of the resin are improved, which facilitates continuous filtration and discharge. The second drive motor 9 on the cover plate 8 drives the scraping component to operate. During the stirring process, the scraping component scrapes the resin impurities on the filter plate 13 to prevent the filter holes 14 from clogging. Multiple sets of filter plates 13 sequentially perform multi-stage filtration of the resin. Multiple sets of filter plates 13, together with the filter holes 14, form a multi-stage filtration structure, which can achieve step-by-step filtration of impurities of different sizes, improving filtration efficiency and resin purity. The overall structure is compact and has a high degree of functional integration, making it suitable for the continuous processing needs of high-purity resin in sensor production.
[0031] like Figures 1-5 As shown, the scraping assembly includes a stirring shaft 11 located at the output end of the second drive motor 9. Multiple sets of rotating rings 15 are sleeved on the stirring shaft 11, and multiple cleaning plates 16 are mounted on the rotating rings 15. The cleaning plates 16 are telescopic, and a return spring is installed inside each cleaning plate 16. The cleaning plates 16 are inclined, and their bottoms are in contact with the surface of the filter plate 13. A contact head 17 is located at the top of one end of the cleaning plate 16, and a collection plate 18 is located at the bottom of one end of the cleaning plate 16. The collection plate 18 is scoop-shaped. Multiple sets of stirring blades 12 are mounted on the stirring shaft 11. The stirring blades 12 are inclined and used to stir the resin raw materials inside the mixing tank body 7. A discharge pipe 10 is located at the bottom of the mixing tank body 7. The discharge pipe 10 is conical, and the filter plate 13 inside the discharge pipe 10 changes with the diameter of the discharge pipe 10. Under normal conditions, the return spring in the cleaning plate 16 keeps the cleaning plate 16 away from the inner wall of the mixing tank body 7.
[0032] The second drive motor 9 drives the stirring shaft 11 to rotate. Multiple sets of stirring blades 12 are mounted on the stirring shaft 11. These blades are inclined, effectively agitating the resin raw material during stirring, promoting uniform mixing and preventing localized sedimentation. Simultaneously, multiple sets of rotating rings 15 mounted on the stirring shaft 11 drive multiple cleaning plates 16 to move synchronously during rotation. The cleaning plates 16 are arranged at an angle, with their bottoms adhering to the surface of the filter plate 13, thus scraping away attached impurities. This synchronous scraping action during stirring effectively prevents blockage of the filter plate 13 due to impurity accumulation, improving filtration efficiency and continuous operation capability. The cleaning plates 16 are equipped with return springs, allowing them to elastically return to their original position when not under stress, thus moving away from the inner wall of the mixing tank body 7 and avoiding unnecessary friction. The internal filter plates 13 are arranged in stages along the diameter of the discharge pipe 10, achieving multi-stage filtration and ultimately discharging pure resin raw material. This ensures stable output quality and meets the resin purity requirements for high-quality sensor production.
[0033] like Figures 1-4 and Figure 6 As shown, the discharge pipe 10 is provided with multiple sets of guide grooves 19, which are inclined and symmetrically distributed on the discharge pipe 10; a sliding groove 20 is opened at one end of the guide groove 19, and a lifting plate 21 is slidably arranged in the sliding groove 20; a guide plate 22 is provided at one end of the lifting plate 21, and the guide plate 22 is inclined to one side; the contact head 17 has an arc-shaped structure that bends to one side, and the contact head 17 can contact the guide plate 22;
[0034] As the cleaning plate 16 rotates, it cleans the impurities on the surface of the filter plate 13. When the impurities approach the cleaning plate 16 as it rotates, it moves the cleaning plate 16, which in turn allows the contact head 17 to contact the guide plate 22, achieving mechanical linkage without an additional power source. This drives the automatic lifting of the lifting plate 21, thereby enabling the impurities to be discharged from the filter plate 19 and assisting in the impurity discharge function during the resin discharge process.
