DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further describes the present utility model in conjunction with specific implementation cases and the attached Figures 1 to 5 drawings, but the present utility model is not limited to these embodiments.

[0028] Refer to Figures 1 to 5 As shown, a sugar screening machine includes a vibration assembly and a screening assembly. The screening assembly is arranged above the vibration assembly, and the vibration assembly drives the screening assembly to vibrate to achieve the vibration screening of the entire device. A feeding cylinder 3 is connected to the screening assembly. The top end of the feeding cylinder 3 is connected to a feeding port 4. When screening sugar, the sugar can be put into the feeding cylinder 3 through the feeding port 4. One end of a plurality of support rods 5 is installed in the feeding port 4, and the other end of the support rod 5 is fixedly installed with a housing 6. The housing 6 and the feeding port 4 can be connected through the support rod 5 to ensure the stability of the position of the housing 6. The centers of the housing 6, the feeding port 4, and the feeding cylinder 3 are located on the same vertical line. A driving assembly is arranged at the housing 6, and a knocking and dispersing assembly and a rotating and dispersing assembly are arranged on the driving assembly. The inner wall of the feeding port 4 can be knocked by the knocking and dispersing assembly to knock and disperse the sugar in the feeding port 4, avoiding sugar caking and accumulation from affecting subsequent screening. The knocking and dispersing assembly is arranged in the feeding port 4, and the rotating and dispersing assembly is arranged in the feeding cylinder 3. The sugar can be further rotated, dispersed, and stirred in the feeding cylinder 3 through the rotating and dispersing assembly, ensuring that the sugar enters the subsequent screening process in a dispersed form and ensuring the efficient progress of the screening process.

[0029] Specifically, mainly refer to Figures 2 to 4 As shown, the driving assembly includes a driving shaft 7 rotatably connected to the middle part of the housing 6 through a bearing, and the bottom end of the driving shaft 7 extends downward into the inner cavity of the feeding cylinder 3. A motor bracket 8 is installed on the housing 6, and a motor 9 is installed on the motor bracket 8. The output end of the motor 9 is connected to the driving shaft 7. By starting the motor 9, the driving shaft 8 can be driven to rotate, so as to prompt the knocking and dispersing assembly and the rotating and dispersing assembly to disperse the sugar synchronously.

[0030] Refer to Figure 4 and Figure 5 As shown, the knocking and dispersing assembly includes an eccentric wheel 10 eccentrically installed on the driving shaft 7, and also includes a plurality of moving arms 11 slidably penetrating the side wall of the housing 6 outward. A hemispherical body 12 is installed at each end of each moving arm 11 away from the housing 6. A stop block 13 is installed at the end of the moving arm 11 close to the housing 6. A first spring 14 is sleeved on the moving arm 11, and both ends of the first spring 14 are connected to the stop block 13 and the outer wall of the moving arm 11 respectively;

[0031] By rotating the drive shaft 7, the eccentric wheel 10 and the dispersion blades 16 on the drive shaft 7 are synchronously rotated. When the eccentric side of the rotating eccentric wheel 10 gradually fits against the stop block 13, the drive stop block 13, the moving arm 11 and the hemispherical body 12 move synchronously away from the housing 6, realizing that the moving arm 11 and the hemispherical body 12 impact the inner wall of the feeding port 4. At this time, the first spring 14 on the moving arm 11 is forced to compress. When the eccentric side of the eccentric wheel 10 rotates away from the stop block 13, at this time, the stop block 13 moves towards the housing 6 under the elastic force of the first spring 14, so that the moving arm 11 and the hemispherical body 12 no longer impact the inner wall of the feeding port 4. By the rotation of the eccentric wheel 10, multiple groups of circumferentially arranged moving arms 11 and hemispherical bodies 12 are driven to alternately and intermittently impact the inner wall of the feeding port 4, so as to realize the vibration dispersion of the sugar in the feeding port 4.

[0032] In addition, the intervals between adjacent moving arms 11 are the same, thus ensuring that the knocking vibration forces in all directions in the feeding port 4 are uniform, and being more capable of uniformly vibrating and dispersing the sugar in the feeding port 4.

[0033] Specifically refer to Figure 3 and Figure 4 As shown, the rotary dispersion assembly includes a plurality of socket seats 15 installed on the drive shaft 7, and the socket seats 15 are arranged in the inner cavity of the guide cylinder 3. A plurality of dispersion blades 16 are equidistantly arranged on each socket seat 15. As the drive shaft 7 rotates, the multiple groups of dispersion blades 16 arranged on the bottom socket seat 15 are synchronously rotated circumferentially. Through the inclined dispersion blades 16, the sugar can be rotated and stirred during the rotation process to avoid sugar caking, realizing further rotary dispersion of the sugar before feeding; the dispersion blades 16 are inclined by 45 degrees relative to the socket seat 15. Therefore, compared with the vertically arranged dispersion blades 16, the contact area between the dispersion blades 16 and the sugar in the guide cylinder 3 can be increased more, and the rotary dispersion of the sugar in the guide cylinder 3 can be realized more effectively.

[0034] Specifically refer to Figure 1 and Figure 2 As shown, the vibration assembly includes a base 1. A vibration motor 17 is installed in the middle of the base 1. A number of second springs 18 are equidistantly arranged on the base 1 in the circumferential direction. The screening assembly includes a plurality of screening bins 2 installed on the vibration motor 17. An outlet 19 is arranged on the side wall of each screening bin 2. Among them, the top of the second spring 18 is connected to the lower surface of the screening bin 2. When the screening bin 2 vibrates relative to the base 1 through the second spring 18, the elastic connection between the screening bin 2 and the base 1 is realized by means of the second spring 18; the sugar falling through the guide cylinder 3 is screened in the screening bin 2. By opening the second spring 18, the whole equipment is vibrated to realize the vibration screening of the sugar. After screening, the corresponding oversize and undersize materials are respectively discharged and collected outward through the outlets 19 at the corresponding positions.

[0035] It should be noted that in this application, the motor 9 uses a self-locking motor commonly used in the market with a lockable output end. Its output end can be self-locked during shutdown and will not rotate under external force. The vibration motor 17 is a commonly used vibration motor in the screening field in the market, and it only needs to meet the requirements of vibration screening. There is no need to elaborate and limit the above existing components too much here.

[0036] The working principle of a sugar screening machine in this embodiment is as follows:

[0037] The sugar to be screened is put down through the feeding port 4. Under the action of the started motor 9, the driving shaft 7 is driven to rotate, so that the eccentric wheel 10 and the dispersion blades 16 on the driving shaft 7 rotate synchronously. When the eccentric side of the rotating eccentric wheel 10 gradually fits the stop block 13, the stop block 13, the moving arm 11 and the hemispherical body 12 are driven to move away from the housing 6 synchronously, realizing that the moving arm 11 and the hemispherical body 12 impact the inner wall of the feeding port 4. At this time, the first spring 14 on the moving arm 11 is forced to compress. When the eccentric side of the eccentric wheel 10 rotates away from the stop block 13, at this time, the stop block 13 moves towards the housing 6 under the elastic force of the first spring 14, so that the moving arm 11 and the hemispherical body 12 no longer impact the inner wall of the feeding port 4. By the rotation of the eccentric wheel 10, multiple groups of circumferentially arranged moving arms 11 and hemispherical bodies 12 are driven to alternately and intermittently impact the inner wall of the feeding port 4, so as to realize the vibration dispersion of the sugar in the feeding port 4; at the same time, as the driving shaft 7 rotates, multiple groups of dispersion blades 16 arranged on the bottom socket 15 are driven to rotate circumferentially synchronously. Through the inclined dispersion blades 16, the sugar can be rotated and stirred during the rotation process to avoid sugar caking, realizing further rotational dispersion of the sugar before being put in;

[0038] The sugar falling through the guide cylinder 3 is screened in the screening bin 2. By starting the second spring 18, the whole device is vibrated to realize the vibration screening of the sugar. After screening, the corresponding oversize and undersize materials are discharged and collected outward through the discharge ports 19 at the corresponding positions respectively;

[0039] The utility model can carry out vibration dispersion and rotational dispersion on the sugar put in the feeding port 4 and the guide cylinder 3, ensure that the sugar enters the subsequent sugar screening processing steps more dispersedly, effectively avoid the problem of sugar caking and accumulation compared with the traditional method, is more conducive to the rapid and effective progress of sugar screening processing, ensures the screening efficiency, and can realize the synchronous action of vibration dispersion and rotational dispersion with the same driving force, saving the energy consumption of the equipment, and having higher coordination and being easier to maintain.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
