Description

Technical Field

[0001] The utility model relates to the technical field of gypsum boards, and more specifically, to a feeding hopper for the production of paper-faced gypsum boards that prevents blockage. Background Art

[0002] Paper-faced gypsum board is a kind of board made mainly of building gypsum, with appropriate additives and fibers incorporated as the board core, and a special board paper as the face. The paper-faced gypsum board has many advantages such as light weight, fire resistance, sound insulation, heat preservation, convenient construction, and environmental friendliness, and is widely used in the interior partitions, ceilings, sound-absorbing boards, floor baseboards, and various decorative boards of various buildings such as residential houses, office buildings, stores, hotels, and industrial factories.

[0003] The feeding hopper for the production of paper-faced gypsum boards is an important component on the production line of paper-faced gypsum boards, mainly used to uniformly feed raw materials (such as gypsum powder, etc.) onto the production line at a certain speed and flow rate to ensure the continuity and stability of the production process.

[0004] There are many problems in the actual use of the existing feeding hoppers for the production of paper-faced gypsum boards. First, if the moisture content of raw materials such as gypsum powder is too high, it is easy to form lumps, which will then cause accumulation and blockage in the feeding hopper. At the same time, larger particles may also get stuck at the outlet or narrow parts of the feeding hopper, seriously hindering the normal flow of materials. Once this situation occurs and the bottom of the feeding hopper becomes blocked, it will greatly affect the subsequent production and processing, bringing great troubles to the actual application.

[0005] Second, during the process of discharging the raw materials for the production of existing gypsum boards through the feeding hopper, due to the humidity, the raw materials often form a certain amount of caking on the inner wall of the feeding hopper. As time goes by, the caking will gradually occupy the internal space of the feeding hopper, reducing the size of the effective feeding channel. This will not only cause the feeding speed to slow down and may even completely block the feeding port, but also the existence of the caking may cause some raw materials not to be evenly mixed during the feeding process, thus disrupting the composition ratio of the paper-faced gypsum board and further affecting the performance and quality of the product. This series of problems undoubtedly cause a lot of inconvenience to the actual application.

[0006] In view of this, we propose a feeding hopper for the production of paper-faced gypsum boards that prevents blockage. Content of the Utility Model

[0007] 1. Technical Problems to be Solved

[0008] The purpose of the present utility model is to provide a feeding hopper for the production of paper-faced gypsum boards that prevents blockage, so as to solve the problems raised in the above background art.

[0009] 2. Technical Solutions

[0010] A blanking hopper for the production of anti-blocking gypsum board, including a mounting frame, an ultrasonic generator is arranged at the top of the mounting frame, a discharging barrel is fixedly sleeved at the top of the mounting frame, a mounting sleeve is arranged on the circumferential outer wall of the bottom of the discharging barrel, and an ultrasonic vibrating rod electrically connected to the ultrasonic generator is arranged on the inner wall of the mounting sleeve. A rotating toothed cover is rotatably connected to the top of the discharging barrel, a feeding port is arranged at the top of the rotating toothed cover, and a fixed cylinder and a scraper are arranged at the bottom of the rotating toothed cover.

[0011] Preferably, a connecting frame is arranged at the bottom of the discharging barrel, and a baffle plate is slidably connected inside the connecting frame.

[0012] Preferably, an inclined pressing frame and a fixing plate are arranged on the circumferential outer wall of the discharging barrel, a rotating motor is arranged at the bottom of the fixing plate, and an output end of the rotating motor is connected with a gear meshing with the rotating toothed cover.

[0013] Preferably, a fixing ring is arranged on the inner wall of the fixed cylinder, a spring is arranged at the top of the fixing ring, and a guiding sliding groove is opened on the inner wall of the fixed cylinder.

[0014] Preferably, the end of the spring is connected with a connecting ring, and a guiding sliding block matched with the guiding sliding groove is arranged on the circumferential outer wall of the connecting ring.

[0015] Preferably, a connecting rod is fixedly sleeved inside the connecting ring, a connecting column is arranged at the bottom of the connecting rod, and discharging blades are arranged on the circumferential outer wall of the connecting column.

[0016] Preferably, the top of the connecting rod extends to the outside above the rotating toothed cover, and a rotating roller is also rotatably connected to the outer wall of the connecting rod.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present utility model are as follows: when blanking the raw materials of the gypsum board, the rotating motor can be fully utilized to drive the rotating toothed cover to rotate. During the rotation of the rotating toothed cover, the rotating roller on the outer wall of the connecting rod will rotate together. When the rotating roller moves to the inclined pressing frame, due to the pressing action of the inclined pressing frame, the connecting rod will be lifted at this time. And when passing through the inclined pressing frame, the connecting rod will rebound and descend due to the action of the spring. With the resilience of the spring, it can drive the connecting column carrying the discharging blades to move up and down the discharging port at the bottom of the discharging barrel. And the multiple discharging blades are streamlined and can further discharge the materials with the rotation. And in this process, the mounting sleeve carrying multiple ultrasonic vibrating rods will vibrate the discharging barrel. Through this compound processing method, the risk of blockage at the discharging port can be greatly reduced;

[0019] In addition, during the rotation of the rotating toothed cover, its scraper will also scrape the inner wall of the feeding bucket. In this way, combined with the action of ultrasonic vibration, it can effectively reduce the formation of caking on the inner wall of the feeding bucket, thereby better reducing the problems that affect the feeding stability and material quality due to caking.

[0032] Specifically, a connecting frame 210 is provided at the bottom of the discharge bucket 200. A baffle 211 is slidably connected inside the connecting frame 210, which is convenient for limiting the material.

[0033] Further, an inclined pressing frame 220 and a fixing plate 230 are provided on the circumferential outer wall of the feeding barrel 200.

[0040] Working principle: When cutting the raw materials of paper-faced gypsum board, the rotating motor 231 can be fully utilized to drive the rotating tooth pattern cover 300 to rotate. During the rotation of the rotating tooth pattern cover 300, the rotating roller 345 on the outer wall of its connecting rod 342 will rotate accordingly. When the rotating roller 345 moves to the inclined pressing frame 220, due to the pressing action of the inclined pressing frame 220, the connecting rod will be lifted at this time. And when passing through the inclined pressing frame 220, the connecting rod 342 will rebound and descend due to the action of the spring 332. With the resilience of the spring 332, it can drive the connecting column 343 carrying the discharge blade 344 to move up and down the discharge port at the bottom of the discharge barrel 200. And the multiple discharge blades 344 are streamlined, and the materials can be further discharged as they rotate.
