Description

Technical Field

[0001] This utility model relates to the field of ointment processing technology, and in particular to a raw material grinding device for ointment production. Background Technology

[0002] In the production of ointments containing traditional Chinese medicine ingredients, the raw materials of the medicinal herbs need to be ground to meet the preparation requirements. Existing equipment for grinding medicinal herbs has the following problems: during the grinding process, some herbs fall into the finished product hopper below the equipment due to compression deformation and other reasons without being fully ground. This results in uneven particle size of the ground herbs, requiring additional sieving and filtering, which increases the labor intensity and construction cost in the production process. At the same time, the additional production steps also reduce production efficiency. Therefore, there is an urgent need for a raw material grinding device for ointment production that can filter the ground powder and lift and transport the large pieces of herbs filtered out for a secondary grinding operation. Utility Model Content

[0003] The purpose of this invention is to provide a raw material grinding device for ointment production, which can filter and sieve the powder that falls off after grinding, screen out large pieces of medicinal materials that are not fully ground, and lift and transport them into the grinding chamber for further grinding, thereby ensuring the quality of the finished product, avoiding additional workload, reducing production costs, and improving production efficiency.

[0004] The present invention adopts the following technical solution:

[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0020] like Figures 1 to 3As shown, the present invention discloses a raw material grinding device for ointment production, comprising a housing 1, a grinding chamber 2 extending vertically through the housing 1, a grinding head 3 disposed within the grinding chamber 2, the grinding head 3 being connected to a rotating shaft 5 driven by a motor 4, a sieve 6 disposed within the housing 1 below the grinding chamber 2, and a receiving bin below the sieve 6, with a discharge pipe equipped with a valve at the bottom of the receiving bin; the rotating shaft 5 passing through the grinding head 3, and a cleaning rod 7 disposed on the rotating shaft 5 located below the grinding head 3, initially contacting the top of the sieve 6; a screw conveyor 8 being conductively disposed on one side of the housing 1, with the outlet end of the screw conveyor 8 passing through the housing 1 and located above the grinding chamber 2. During operation, the medicinal materials enter the grinding chamber 2 and are ground and crushed by the grinding head 3. The ground medicinal materials fall onto the screening screen 6 below. As the rotating shaft 5 rotates, the cleaning rod 7 pushes the qualified medicinal material powder into the hopper below the screening screen 6 to improve screening efficiency. On the other hand, it pushes the large pieces of medicinal materials remaining on the screening screen 6 into the screw conveyor 8, which lifts and transports them to the grinding chamber 2 to complete the secondary grinding operation, thereby ensuring the grinding quality of the medicinal materials. Under normal circumstances, there will not be too many large particles of medicinal materials screened out during the grinding process. At this time, it is only necessary to keep the screw conveyor 8 running at regular intervals.

[0021] In this embodiment, the grinding chamber 2 is an inverted frustum-shaped structure with a large opening at the top and a small opening at the bottom, and the grinding head 3 matches its shape. To improve the grinding effect, preferably, the grinding head 3 has a convex arc-shaped structure on the outside, forming a structure with a large gap at the top and bottom and a small gap in the middle between the grinding head 3 and the inner wall of the grinding chamber 2. This allows the medicinal materials to be gradually ground after entering the grinding chamber 2, and the increased gap at the bottom after grinding allows for smooth discharge of the ground material. In this embodiment, the grinding head 3 can be adjusted axially along the rotating shaft 5 to adjust the gap between the grinding head 3 and the grinding chamber 2 to meet the grinding requirements of different particle sizes. The grinding head 3 and the rotating shaft 5 can be fixed by, but not limited to, bolt connections. Since there are various adjustable and fixed connection methods, the specific method can be flexibly adapted according to the actual situation.

[0022] Furthermore, the screening screen 6 has a conical structure, which increases the area for filtering and screening the ground powder, improves the efficiency of screening qualified powder, and reduces the amount of qualified powder entering the screw conveyor 8. Simultaneously, large pieces of material screened out can accumulate at the bottom of the screening screen 6, and are then concentrated and pushed into the screw conveyor 8 by the cleaning rod 7. The cleaning rod 7 is arranged inclined along the surface of the screening screen 6. In addition, to improve the screening effect, bristles can be provided on the end face of the cleaning rod 7 opposite to the screening screen 6, which can both sweep qualified powder below the screening screen 6 and reduce friction between the rod and the screening screen 6.

[0023] Furthermore, a receiving ring 9 is provided between the bottom of the screening mesh 6 and the inner wall of the shell 1, and the cleaning rod 7 extends to the receiving ring 9, preferably with bristles at its bottom; the receiving ring 9 is used to receive large pieces of medicinal materials screened out by the screening mesh 6, providing a temporary holding platform for medicinal materials falling along the slope of the screening mesh 6, so that as the cleaning rod 7 rotates, the large pieces of medicinal materials are pushed orderly into the screw conveyor 8. Preferably, in this embodiment, the end of the receiving ring 9 that contacts the screw conveyor 8 is inclinedly provided with a guide groove 10, so that as the cleaning rod 7 rotates, the large pieces of medicinal materials are pushed into the guide groove 10 and smoothly enter the screw conveyor 8 along the slope of the guide groove 10; wherein the shell 1 and the inlet end of the screw conveyor 8 are also connected by an inclined through hole, that is, the shell 1 is inclined downwards towards the screw conveyor 8 to facilitate the smooth sliding of the medicinal materials.

[0024] Furthermore, in this embodiment, the rotating shaft 5 extends below the sieve screen 6 and is movably connected to the sieve screen 6; a flexible striking belt 11 is provided on the rotating shaft 5 located below the sieve screen 6. The striking belt 11 can be made of rubber material. During operation, the striking belt 11 will extend as the rotating shaft 5 rotates and strike the bottom of the sieve screen 6, which helps the qualified medicinal powder to fall and large pieces of medicinal materials to fall off.

[0025] Furthermore, a pulverizing blade 12 is provided on the rotating shaft 5 above the grinding head 3. The pulverizing blade 12 can be the first to contact the medicinal material after it is added into the housing 1 to complete the initial pulverization. The pulverized medicinal material is thrown into the grinding chamber 2 for grinding under the rotation of the grinding head 3, which can improve the grinding efficiency and ensure the grinding effect.

[0026] Furthermore, in this embodiment, a sealing cover 13 is provided at the top of the housing 1, the motor 4 is mounted on the sealing cover 13, and an inspection door 14 is provided on the side wall of the housing 1 corresponding to the sieve screen 6. The sealing cover 13 and the inspection door 14 facilitate the inspection and maintenance of the internal structures such as the grinding head 3 and the sieve screen 6. In addition, a feeding port 15 is provided on one side of the housing 1, and a guide plate 16 is hinged to the feeding port 15 to facilitate the smooth addition of Chinese medicinal materials.

[0027] When this invention is in operation, the motor 4 is started, and the Chinese herbal medicine materials are added into the housing 1. Most of the herbs will come into contact with the crushing blades 12 and be crushed first. Then, they are thrown into the grinding chamber 2 and ground by the grinding head 3. After grinding, the herbs fall onto the screening screen 6 below. Herbal powder with the correct particle size falls into the hopper below the screening screen 6 and is finally discharged from the discharge port at the bottom of the hopper. Large pieces of herbs retained on the screening screen 6 will fall onto the receiving ring 9 along the surface of the screening screen 6. With the rotation of the cleaning rod 7, they are pushed into the guide chute 10, and the guide chute 10 completes the conveying to the screw conveyor 8. The screw conveyor 8 then lifts the screened herbs and conveys them into the housing 1 above the grinding cylinder to complete the crushing and grinding operation again, thereby ensuring the grinding quality.
