Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example

[0028] Please see Figures 1-6 This utility model provides a vibrating screen for screening food additives, including a housing 100 and an anti-clogging component 200.

[0029] The anti-clogging component 200 is installed on the bottom plate 130 of the housing 100. The anti-clogging component 200 can clean the particulate impurities that block the screen holes, reducing the possibility that the screen holes of the screening plate 151 will be easily blocked by particulate impurities during long-term use.

[0030] Please see Figures 1-4 The top of the box 100 is connected to a feed pipe 110, and the bottom of the box 100 is connected to a buffer spring 120. The lower end of the buffer spring 120 is connected to a base plate 130. A vibration motor 140 is installed at the bottom of the box 100, and a sieving element 150 and a collection dish 160 are slidably arranged inside the box 100. In specific implementation, the base plate 130 and the buffer spring 120 can provide a certain support and buffer for the box 100. The raw materials of the food additive are added into the box 100 through the feed pipe 110. The raw materials of the food additive will fall onto the sieving element 150. By starting the vibration motor 140, the box 100 and the sieving element 150 can vibrate, which is conducive to the sieving of the food additive. Large particles of impurities will accumulate on the surface of the sieving element 150, and the sieved food additive will fall into the collection dish 160.

[0031] In this embodiment, buffer blocks 180 are provided on the lower surface of the box 100 and the upper surface of the base plate 130. Several buffer blocks 180 are symmetrically arranged, and buffer pads are connected to the surface of the buffer blocks 180. In specific implementation, when the vibration motor 140 drives the box 100 to vibrate, the buffer blocks 180 at the bottom of the box 100 will contact the buffer blocks 180 on the base plate 130. Through the contact of two adjacent buffer pads, the possibility of collision between the vibration motor 140 and the base plate 130 can be reduced. It should be noted that the buffer pads are made of rubber or silicone. Support blocks 190 are connected inside the box 100. Several support blocks 190 are provided, and the screening component 150 is located between two adjacent support blocks 190.

[0032] The screening component 150 includes a screening plate 151 and a first pull block 152. Both the upper and lower surfaces of the screening plate 151 are in contact with the support block 190, and the screening plate 151 is fixedly connected to the first pull block 152. A first sealing gasket is provided between the first pull block 152 and the housing 100, and a first handle is connected to the surface of the first pull block 152. In specific implementation, the support block 190 can restrict the vertical movement of the screening plate 151, facilitating the stability of the screening plate 151 within the housing 100. After screening the food additives, the first pull block 152 and the screening plate 151 can be removed from the housing 100 by pulling the first handle, facilitating the cleaning of particulate impurities on the upper surface of the screening plate 151. The first sealing gasket improves the sealing performance of the connection between the first pull block 152 and the housing 100. The first and second sealing gaskets are made of rubber or silicone. The lower surface of the collecting dish 160 is attached to the bottom wall of the box 100, and a second pull block 161 is connected to the surface of the collecting dish 160. A second sealing gasket is provided between the second pull block 161 and the box 100, and a second handle is connected to the surface of the second pull block 161. A stop block 162 is bolted to the surface of the box 100. The stop block 162 is attached to the first pull block 152 and the second pull block 161 respectively. In specific implementation, the stop block 162 can restrict the first pull block 152 and the second pull block 161, which is beneficial to prevent the collecting dish 160 and the sieve plate 151 from shaking during the vibration of the box 100. By removing the bolts, the stop block 162 can be removed, making it easy to take out the collecting dish 160 and the sieve plate 151.

[0033] Please see Figures 1-6The anti-clogging component 200 includes a motor 210 and a connecting rod 220. A bracket 170 is connected to the upper surface of the base plate 130. The motor 210 is mounted on the top of the bracket 170, and the output shaft of the motor 210 is fixedly connected to the connecting rod 220. A limiting member 230 is slidably provided at the lower end of the connecting rod 220, and a first spring 240 is connected inside the connecting rod 220. The lower end of the first spring 240 is connected to the limiting member 230. A cleaning brush 250 is connected to the lower end of the limiting member 230. The cleaning brush 250 is in contact with the upper surface of the screening component 150. In specific implementation, the motor 210 is mounted on the bracket 170 to reduce the impact of vibration on the housing 100. The possibility of damage due to vibration is reduced. During the screening process, the motor 210 is started, and its output shaft drives the connecting rod 220 to rotate. The cleaning brush 250 will rotate along the upper surface of the screening plate 151. Since the limiting member 230 is slidably set in the connecting rod 220, and the lower end of the first spring 240 in the connecting rod 220 is connected to the limiting member 230, the possibility of damage to the cleaning brush 250 and the cleaning block 251 during the vibration of the screening plate 151 can be reduced. By cleaning the screening plate 151 with the cleaning brush 250, the possibility of the screen holes of the screening plate 151 being easily blocked by particulate impurities during long-term use is reduced.

[0034] In this embodiment, the bracket 170 is L-shaped, and a protective pad 171 is connected to the side of the bracket 170. The protective pad 171 is located on one side of the box 100. An elastic ring 260 is provided between the connecting rod 220 and the box 100. In specific implementation, when the box 100 vibrates, the protective pad 171 connected to the side of the bracket 170 reduces the possibility of the box 100 colliding with the bracket 170. The elastic ring 260 provided between the connecting rod 220 and the box 100 can reduce the possibility of the connecting rod 220 colliding with the box 100 during the vibration of the box 100. It should be noted that the elastic rod 280, the protective pad 171 and the elastic ring 260 are made of rubber or silicone. The first spring 240 is connected to the top wall of the placement groove 221, and the limiting member 230 is attached to the inner wall of the placement groove 221.

[0035] The limiting component 230 includes a limiting block 231 and a movable rod 232. Both the limiting block 231 and the movable rod 232 are slidably disposed within the placement groove 221, with the limiting block 231 fitting against the inner wall of the placement groove 221. The movable rod 232 is fixedly connected to the limiting block 231. A guide block 270 is connected to the side of the limiting block 231. A guide groove corresponding to the guide block 270 is formed in the connecting rod 220. In specific implementation, when the screening plate 151 vibrates, the first spring 24... With a force of 0, the cleaning brush 250 will cause the movable rod 232 to move up and down. The guide block 270 on the side of the limiting block 231 will move up and down along the inner wall of the guide groove, which is beneficial to the stability of the limiting block 231 during movement and reduces the possibility that the limiting block 231 cannot rotate when the connecting rod 220 rotates. The lower end of the movable rod 232 is connected to the elastic rod 280, and the lower end of the elastic rod 280 is connected to the cleaning block 251, which is connected to the cleaning brush 250.

[0036] Specifically, the working principle of this vibrating screen for food additive sieving is as follows: During use, the raw materials for the food additive are added into the housing 100 through the feed pipe 110. The base plate 130 and the buffer spring 120 provide support and cushioning for the housing 100. By starting the vibrating motor 140, the housing 100 and the screening plate 151 vibrate, facilitating the sieving of the food additive. The sieved food additive falls into the collection dish 160. By starting the motor 210 on the support 170, its output shaft drives the connecting... When the connecting rod 220 rotates, it drives the limiting block 231, the movable rod 232, and the elastic rod 280 to rotate, which in turn drives the cleaning brush 250 to rotate along the surface of the screening plate 151. This can clean the particulate impurities on the upper surface of the screening plate 151, reducing the possibility that the screen holes of the screening plate 151 will be easily blocked by particulate impurities during long-term use. Connecting the lower end of the first spring 240 to the limiting block 231 can reduce the possibility that the cleaning block 251 will collide with the screening plate 151 and be damaged during vibration.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
