Description

Technical Field

[0001] The utility model relates to the technical field of protein powder production, in particular to a grinding device for protein powder production. Background Art

[0002] Protein powder is a protein needed by the human body. The protein powder on the market is generally protein purified from soybeans or milk. Protein powder is mainly suitable for nutritional supplements such as trauma, burns, large-area skin ulcers, tumor radiotherapy and chemotherapy. Generally, this situation will lead to severe protein loss and the body is in a negative nitrogen balance state. For these patients in the recovery period of treatment or in the postoperative recuperation stage, they cannot ensure the diversity of food intake like normal people, so choosing protein powder and similar nutritional products is a shortcut to supplement protein. Crystallized protein powder requires a grinder when processing.

[0003] In the related art, Chinese patent document with application number CN202222964387.5 proposes a grinder, which starts a crusher and then pours the material into a lower hopper. The material falls into the crusher, and the crusher can break up large pieces of material to facilitate subsequent grinding. When the material does not need to be ground, people turn off the crusher.

[0004] Regarding the above-mentioned related technologies, the inventors believe that there are the following defects: the device is often used in conjunction with a crushing device when grinding protein powder. During the use of the current crushing device, the feed hopper is often open, causing the protein powder to splash everywhere when it is crushed, making it inconvenient to clean. In view of this, a grinding device for protein powder production is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-2 , a protein powder production grinding device in this embodiment includes a bottom box 1, a bracket 3 is fixed on the bottom box 1, a feed hopper 6 is fixed on the bracket 3, a lower grinding disc 5 is provided at the upper end of the bottom box 1, an upper grinding disc 2 is provided at the bottom of the feed hopper 6, a gear ring is fixed to the outside of the upper grinding disc 2, and a plurality of scrapers are provided on the outside of the upper grinding disc 2. A discharge pipe is provided on the bottom box 1, which is conducive to pushing the protein powder into the extension tube, and a grinding assembly 4 is provided in the feed hopper 6, which is conducive to basic crushing of the protein powder. A closing mechanism 7 is provided on the feed hopper 6;

[0025] The closing mechanism 7 includes a rotating shaft 710, a fixed cylinder 704, a guide wheel 714, a control terminal 716, and a protective box 701. The rotating shaft 710 is symmetrically mounted on the top of the feed hopper 6. A sealing plate 713 is fixed to the outside of the rotating shaft 710. Second connecting rods 709 are fixed to opposite sides of the two rotating shafts 710. One end of the second connecting rod 709 is connected to the first connecting rod 708.

[0026] Two fixed cylinders 704 are obliquely provided on the feed hopper 6. A long hole is opened on the front of the fixed cylinder 704. The slider 706 and the first connecting rod 708 are both located outside the long hole to prevent the fixed cylinder 704 from interfering with the movement of the first connecting rod 708 when moving up and down. A fixed block 707 is fixed to the top of the inner side of the fixed cylinder 704. A slider 706 that can move up and down is slidably installed in the fixed cylinder 704. One end of the slider 706 is hinged to the first connecting rod 708. A retaining ring 715 is fixed to the bottom of the fixed cylinder 704. A spring 705 is fixed on the retaining ring 715. The other end of the spring 705 is fixed to the slider 706.

[0027] A protective box 701 is fixed to the middle of the side of the feed hopper 6, and a rotatable turntable 702 is horizontally arranged in the protective box 701. A pull rope 703 is wrapped around both ends of the turntable 702, and one end of the pull rope 703 is fixed to the slider 706.

[0028] The device starts an external motor, which drives the turntable 702 to rotate. The turntable 702 pulls the pull ropes 703 on both sides, thereby pulling the slider 706 to move, and then the slider 706 drives the first connecting rod 708 to move, and then the first connecting rod 708 drives the second connecting rod 709 to move, so that the second connecting rod 709 drives the rotating shaft 710 to rotate and tilt, and then the rotating shaft 710 drives the sealing plate 713 to rotate, so that the sealing plate 713 opens, allowing the protein powder raw materials to enter the feed hopper 6.

[0029] One end of the turntable 702 is driven to rotate by an external motor, which is convenient for driving the turntable 702 to rotate. The pull rope 703 is inserted into the spring 705 to facilitate pulling the slider 706.

[0030] At the same time, two guide wheels 714 are rotatably installed on the feed, and the outer side of the pull rope 703 is slidably connected to the guide wheel 714. During the process of pulling the pull rope 703, the friction between the pull rope 703 and the sliding sleeve is reduced, which facilitates better pulling of the slider 706.

[0031] In addition, a plurality of grooves 711 are provided at the top inner side of the feed hopper 6, and infrared sensors 712 are fixed in the grooves 711. The infrared sensors 712 do not contact the sealing plate 713, and the grooves 711 are staggered. By staggering the infrared sensors 712 in the grooves 711, it is convenient to monitor the protein powder falling at different positions. When the infrared sensor 712 detects that there is protein powder in front, the signal is transmitted to the control terminal 716, and then the control terminal 716 controls the external motor to open or close the sealing plate 713.

[0032] A control terminal 716 is fixed on the feed hopper 6 , and the control terminal 716 is electrically connected to the infrared sensor 712 and the external motor respectively, so as to facilitate the control of the infrared sensor 712 and the external motor.

[0033] The working principle of the above embodiment is:

[0034] When the protein powder is ground, the protein powder is added to the inside of the hopper. When the protein powder is poured onto the sealing plate 713, the infrared sensor 712 detects that there is protein powder in front, and transmits a signal to the control terminal 716. The control terminal 716 then controls the external motor to drive the turntable 702 to rotate. The turntable 702 pulls the pull ropes 703 on both sides, thereby pulling the slider 706 to move, and then the slider 706 drives the first connecting rod 708 to move, and then the first connecting rod 708 drives the second connecting rod 709 to move, so that the second connecting rod 709 drives the rotating shaft 710 to rotate and tilt. When tilted, the two sealing plates 713 are in a V-shape, which has a certain diversion effect on the protein powder, and then the rotating shaft 710 drives the sealing plate 713 to rotate, so that the sealing plate 713 opens, and the protein powder raw material can enter the feed hopper 6.

[0035] Then, by reversing the motor and setting the spring 705, the slider 706 is moved to its original position, and at the same time, the first connecting rod 708 and the second connecting rod 709 are driven to move and return to the initial state, so that the two sealing plates 713 are flush, and the feed hopper 6 is closed. This can ensure that when the protein powder is added to the hopper, the dust raised can be sealed inside the hopper to prevent the dust from spreading in the outside air.

[0036] The protein powder then enters the grinding assembly 4 for basic crushing, and then enters between the lower grinding disc 5 and the upper grinding disc 2 for further grinding. After the powder is discharged, the powder is pushed and scraped by a scraper, so that the protein powder enters the discharge pipe and falls into the bottom box 1 for collection.
