Description

Technical Field

[0001] The utility model relates to the technical field of mulberry leaf powder preparation, in particular to a mulberry leaf powder preparation device. Background Art

[0002] Sodium bisulfite is used to protect the color when making mulberry leaf powder. Sodium bisulfite is prepared into a solution with a concentration of 0.25%. 80 kg of 0.25% sodium bisulfite solution is used for every 50 kg of mulberry leaves and 10 kg of wax apples, and the mixture is soaked in a stainless steel barrel to protect the color. The mulberry leaves and wax apples immersed in the color protection solution are then put into a grinder with a rotation speed of 1000 revolutions per minute for crushing and stirring, so that the mulberry leaves, wax apples and the color protection agent are completely mixed. A pulping machine is then used for pulping, and the mulberry leaves that are not completely crushed are removed through the sieve holes of the pulping machine.

[0003] In the process of mixing the crushed mulberry leaves, wax apples and color preservatives, since the fermented mulberry leaf powder, wax apples and color preservatives have a certain viscosity after mixing, it is inevitable that more raw materials will adhere to the inner wall of the mixing box, resulting in waste of raw materials and increasing the production cost of mulberry leaf powder.

[0004] In the prior art, a Chinese patent with the authorization announcement number CN219765077U discloses a mulberry leaf powder preparation device, including a cavity, wherein a main gear, an auxiliary gear, a main rotating shaft, an auxiliary rotating shaft, a stirring blade and a scraper are installed inside the cavity. The main gear and the auxiliary gear can drive the main rotating shaft and the auxiliary rotating shaft to rotate after being matched, so that the stirring blade can cooperate with the scraper to accelerate the mixing of various raw materials, and the scraper can scrape the inner wall of the cavity during rotation, thereby ensuring the removal of raw materials sticking to the inner wall of the cavity.

[0005] The disadvantage of the above-mentioned prior art solution is that since the scraper is fixed and continuously in contact with the inner wall of the cavity, during the stirring and mixing process, the scraper continuously rotates on the inner wall of the cavity, and the friction generated by this movement causes the material on the scraper surface to be gradually consumed. In particular, when mixing raw materials with high viscosity, the friction will be greater, accelerating the wear of the scraper. Utility Model Content

[0006] The utility model aims to provide a mulberry leaf powder preparation device to solve the technical problem in the prior art that the scraper is continuously in contact with the inner wall of the cavity, resulting in rapid wear of the scraper.

[0007] The technical problem to be solved by the utility model can be achieved through the following technical solutions: a mulberry leaf powder preparation device, including a support frame, a mixing drum, a drum cover, a first driving mechanism, a stirring mechanism and a second driving mechanism, the mixing drum is fixedly arranged on the support frame, the drum cover is rotatably arranged on the top of the mixing drum, the first driving mechanism is used to drive the drum cover to rotate on the top of the mixing drum, the stirring mechanism includes a sliding scraper, a support rod and a limit rod, the top of the drum cover is fixedly provided with a horizontal slide groove, the sliding scraper is slidably arranged in the slide groove, one end of the support rod is fixedly arranged at the bottom of the drum cover, the other end of the support rod extends into the mixing drum, the limit rod is fixedly arranged on the side of the support rod, the outer side of the sliding scraper is provided with a limit hole that slidably cooperates with the limit rod, and the second driving mechanism is used to drive the sliding scraper to slide in the slide groove.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 6 As shown, a mulberry leaf powder preparation device includes a support frame 1, a mixing barrel 2, a barrel cover 3, a first driving mechanism 4, a stirring mechanism 5 and a second driving mechanism 6. The mixing barrel 2 is fixed on the support frame 1 by bolts or welding to ensure that the mixing barrel 2 remains stable during the raw material mixing process.

[0028] The bottom of the barrel cover 3 is provided with an annular groove 31 that matches with the top of the mixing barrel 2. The barrel cover 3 is rotatably arranged on the top of the mixing barrel 2. The stirring mechanism 5 is arranged on the barrel cover 3 and extends into the mixing barrel 2. The first driving mechanism 4 is used to drive the barrel cover 3 to rotate on the top of the mixing barrel 2. Specifically, the first driving mechanism 4 includes a driven wheel 41, a driving wheel 42, a synchronous belt 43 and a first rotating motor 44. The first driving mechanism 4 is fixedly arranged on the support frame 1. The driven wheel 41 is fixedly arranged around the edge of the barrel cover 3. The driving wheel 42 is coaxially fixedly connected with the output end of the first rotating motor 44, and the synchronous belt 43 is wound between the driven wheel 41 and the driving wheel 42. The driving wheel 42 is driven to rotate by the first rotating motor 44, and the driven wheel 41 is driven to rotate by the synchronous belt 43, thereby driving the barrel cover 3 to rotate on the top of the mixing barrel 2, and then the stirring mechanism 5 is rotated in the mixing barrel 2, so as to achieve the stirring and mixing of the raw materials in the mixing barrel 2.

[0029] Specifically, the stirring mechanism 5 includes a sliding scraper 51, a support rod 52 and a limit rod 53. The top of the barrel cover 3 is provided with a horizontal slide groove 33, and the slide groove 33 is open at the top and bottom. The sliding scraper 51 is slidably arranged in the slide groove 33. When the sliding scraper 51 slides to the two ends of the slide groove 33, the side of the sliding scraper 51 fits with the inner wall of the mixing barrel 2, so as to scrape off the raw materials attached to the inner wall of the mixing barrel 2. When the sliding scraper 51 slides in the slide groove 33, the sliding scraper 51 can stir the raw materials in the mixing barrel 2. At the same time, the sliding of the sliding scraper 51 in the slide groove 33 also avoids the problem of the sliding scraper 51 continuously contacting the inner wall of the chamber barrel, which causes the sliding scraper 51 to wear faster.

[0030] One end of the support rod 52 is fixedly set at the bottom of the barrel cover 3, and the other end of the support rod 52 extends into the mixing barrel 2. The limiting rod 53 is fixedly set on the side of the support rod 52. A limiting hole that slides with the limiting rod 53 is opened on the outer side of the sliding scraper 51. The sliding cooperation between the limiting rod 53 and the limiting hole is beneficial to the stability of the sliding of the sliding scraper 51 in the slide groove 33.

[0031] The second driving mechanism 6 is used to drive the sliding scraper 51 to slide in the chute 33. The second driving mechanism 6 includes a screw 61 and a second rotary motor 62. The screw 61 is rotatably arranged in the chute 33, the second rotary motor 62 is fixedly arranged on the barrel cover 3, the output end of the second rotary motor 62 is coaxially fixedly connected with the screw 61, and the sliding scraper 51 is provided with a rotating hole that is threadedly matched with the screw 61. The screw 61 is driven to rotate by the second rotary motor 62, and then the rotating hole of the sliding scraper 51 is threadedly matched with the screw 61, so that the sliding scraper 51 can realize reciprocating motion in the mixing barrel 2, further enhancing the stirring effect.

[0032] refer to Figure 3 and Figure 5 As shown, in some specific embodiments, in order to reduce the friction between the mixing barrel 2 and the barrel cover 3, a plurality of grooves are provided on the inner wall of the annular rotating groove 31, and balls 32 are rotatably provided in each of the grooves. When the barrel cover 3 rotates on the top of the mixing barrel 2, the balls 32 roll in the grooves instead of directly contacting the top of the mixing barrel 2, thereby greatly reducing friction and wear and extending the service life of the device.

[0033] refer to Figure 2 and Figure 4 As shown, in some specific embodiments, in order to improve the stirring efficiency and uniformity of the stirring mechanism 5, two sliding scrapers 51 are provided and symmetrically distributed on both sides of the inside of the chute 33, and the screw 61 is provided with symmetrically distributed threads with opposite spiral directions, and the rotating hole of each sliding scraper 51 cooperates with the corresponding thread. The two sliding scrapers 51 work at the same time, which can cover a larger stirring area in a shorter time, thereby improving the stirring efficiency. At the same time, the two sliding scrapers 51 move relative to each other from the two ends of the chute 33, and can push the raw materials to the center of the mixing barrel 2, and meet at the center position to form a convection stirring effect. This stirring method can make the raw materials more evenly mixed in the mixing barrel 2.

[0034] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0035] The driving wheel 42 is driven to rotate by the first rotating motor 44, and the driven wheel 41 is driven to rotate by the synchronous belt 43, thereby driving the drum cover 3 to rotate on the top of the mixing drum 2. The annular groove 31 at the bottom of the drum cover 3 is rotatably matched with the top of the mixing drum 2, and the bottom and side wall of the annular groove 31 are provided with balls 32 to reduce friction and wear.

[0036] When the sliding scraper 51 slides to both ends of the chute 33, the side of the sliding scraper 51 fits against the inner wall of the mixing drum 2 to scrape off the attached raw materials. When the sliding scraper 51 slides in the chute 33, the raw materials in the mixing drum 2 are stirred. The sliding of the sliding scraper 51 in the chute 33 avoids long-term contact between the sliding scraper 51 and the inner wall of the mixing drum 2, reducing wear. The support rod 52 and the limit rod 53 ensure that the sliding scraper 51 slides stably in the chute 33.

[0037] The screw 61 is driven to rotate by the second rotary motor 62, and the rotating hole of the sliding scraper 51 is threadedly matched with the screw 61, so that the sliding scraper 51 can achieve reciprocating motion in the mixing barrel 2, further enhancing the stirring effect.

[0038] Two sliding scrapers 51 are relatively slidably arranged in the chute 33. The screw 61 is provided with symmetrically distributed threads with opposite spiral directions, which cooperate with the rotating holes of the two sliding scrapers 51 to achieve the relative movement of the two sliding scrapers 51. The two sliding scrapers 51 work at the same time, covering a larger mixing area and improving the mixing efficiency; at the same time, the two sliding scrapers 51 move relatively from both ends of the chute 33 to form a convection mixing effect, so that the raw materials are mixed more evenly.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
