Description

Technical Field

[0001] This invention relates to the field of health care ointment preparation technology, and in particular to a joint pain health care ointment and its production equipment. Background Technology

[0002] Joint pain is the most common symptom of joint diseases. In daily life, joints are often damaged by external impacts or excessive extension and twisting, resulting in joint dislocation, fracture, ruptured blood vessels, bleeding, and tissue fluid leakage, which in turn leads to joint swelling and pain. In addition, continuous chronic mechanical damage or rough scars left by joint surface damage after acute trauma can cause the joint lubrication to disappear. Long-term friction on the joint surface can cause chronic damage. Long-term weight-bearing on the joint can damage the articular cartilage and joint surface. Excessive joint movement can cause cumulative damage to the articular cartilage. Improper treatment of joint sprains or poor fracture healing, malunion, and load imbalance caused by malunion can also cause chronic joint damage, which can also cause more severe joint pain.

[0003] Because joint pain is a persistent condition, in addition to routine medication, people often use topical ointments to relieve the pain. For example, the existing published literature CN116585442A - a formulation and preparation method of a topical ointment for joint pain - discloses a topical ointment for the adjunctive treatment of joint pain. However, this type of topical ointment has the disadvantages of low duration of therapeutic effect and poor shaping effect.

[0004] In addition, in the preparation of health ointments, in order to extract the effective components of Chinese medicinal materials, the Chinese medicinal materials are generally placed in a high-temperature extraction solution. The effective components in the Chinese medicinal materials are extracted by soaking in the extraction solution. After extraction, the ointment is obtained by concentration and other methods. For example, existing public documents CN222286451U - a device for soaking and extracting Chinese medicinal materials and existing public documents CN215462172U - a multifunctional extraction tank for preparing Chinese medicine extracts both disclose a production equipment for extracting the effective components of Chinese medicinal materials. Although the above-mentioned production equipment can extract the effective components of Chinese medicinal materials, the extraction temperature varies for different Chinese medicinal materials (e.g., the extraction temperature of oils does not exceed 60℃, the extraction temperature of sugars is 70-100℃, and the extraction temperature of alkaloids is generally 80℃). This leads to the shortcomings of existing extraction devices in extracting the effective components of Chinese medicinal materials, such as incomplete extraction and complicated operation.

[0005] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0011] As a preferred embodiment of the joint pain relief ointment of the present invention, it comprises the following raw materials in parts by weight: 42 parts of Artemisia argyi, 28 parts of Lycopodium clavatum, 26 parts of Phellodendron chinense, 22 parts of Clematis chinensis, 26 parts of Ligusticum chuanxiong, 20 parts of Angelica pubescens, 18 parts of Angelica sinensis, 16 parts of fresh ginger, 16 parts of cinnamon, 12 parts of clove, 18 parts of Achyranthes bidentata, 8 parts of Dipsacus asper, 12 parts of Codonopsis pilosula, 7 parts of Acanthopanax senticosus, 9 parts of Pueraria lobata, 6 parts of Agrimonia pilosa, 8 parts of Saposhnikovia divaricata, 6 parts of Psoralea corylifolia, 10 parts of Acorus tatarinowii, 4 parts of Hirudo medicinalis, 5 parts of Asarum heterotropoides, 4 parts of Dragon's Blood, 5 parts of Frankincense, 2 parts of Myrrh, 4 parts of Borneol, 2 parts of Menthol, 5 parts of Azone, and 1 part of Vaseline.

[0012] The beneficial effects of this invention are as follows: When using this health care ointment, it mainly uses Chinese medicinal herbs, which have high overall safety. The effects of Chinese medicinal herbs include promoting blood circulation and relieving pain, removing dampness and unblocking meridians, dispelling cold and warming the meridians, strengthening tendons and bones, and promoting tissue regeneration. It can effectively improve the treatment effect of joint pain. At the same time, this health care ointment contains a variety of plant lipids, which can be effectively shaped during preparation and can also form a lipid film on the surface of the skin during use, reducing the volatilization of the drug in the air and improving the duration of drug use. Combined with the transdermal properties of azone, it effectively improves the absorption of the drug by the human body, resulting in a significant and effective overall therapeutic effect.

[0013] Given that existing Chinese medicine extraction devices do not achieve ideal extraction results for the effective components of Chinese medicine in actual use, a production equipment for joint pain relief ointment is proposed.

[0014] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: a production equipment for a joint pain relief ointment, the equipment for producing the joint pain relief ointment includes an soaking and extraction mechanism, including an extraction cylinder, an soaking cylinder fixed on the top surface of the extraction cylinder and interconnected with it, a lifting plate disposed inside the extraction cylinder, and a stirring shaft disposed inside the soaking cylinder. A guide rib is fixed on the inner wall of the extraction cylinder in a vertical direction, conforming to the side wall of the lifting plate. Simultaneously, a screw post arranged in a vertical direction is spirally sleeved on the lifting plate. The upper end of the screw post penetrates and extends above the extraction cylinder, fitting into the output end of a first motor. The first motor is fixedly installed on the top surface of the extraction cylinder. An electric heating element is fixed in the lifting plate. A limiting groove is formed circumferentially on the side wall of the lifting plate, and a sealing ring is fitted in the limiting groove with a gap. Multiple placement cylinders communicating with the interior of the extraction cylinder are fixedly connected to the outer wall of the soaking cylinder; and a loading mechanism sleeved in the placement cylinder for holding raw materials, wherein the extraction temperature of the effective components of the raw materials loaded in each loading mechanism increases from bottom to top.

[0015] Another beneficial effect of this invention is that, when using the production equipment, the staff first classifies the medicinal materials according to the extraction temperature of their effective components. Then, according to the extraction temperature, various medicinal materials are placed in the corresponding loading mechanism. Extraction liquid is added to the extraction cylinder, and the electric heating group heats the extraction liquid in the extraction cylinder. The operation of the first motor can drive the lifting plate to move vertically, thus moving the extraction liquid vertically to achieve the extraction liquid immersing into the soaking cylinder. When the temperature of the extraction liquid is low, the extraction liquid first contacts the medicinal materials with lower extraction temperatures at the bottom of the soaking cylinder, extracting the effective components of the medicinal materials. As the temperature of the extraction liquid continues to rise, the lifting plate will drive the liquid level of the extraction liquid in the soaking cylinder to rise, thereby achieving effective soaking of medicinal materials with different extraction temperatures according to the different temperatures of the extraction liquid. This design can effectively extract the effective components from the medicinal materials on the one hand, and avoid the need for staff to adjust the extraction according to the characteristics of the medicinal materials on the other hand. The overall operation is convenient and practical.

[0016] As a preferred embodiment of the production equipment for a joint pain relief ointment of the present invention, a plurality of placement cylinders evenly distributed along the circumference of the soaking cylinder are arranged as a group, and a plurality of groups of placement cylinders are arranged in an array along the axial direction of the soaking cylinder.

[0049] Example 4

[0050] Reference Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 9 This is the fifth embodiment of the present invention. This embodiment provides a production equipment for joint pain relief ointment to realize the soaking of Chinese medicinal materials and the extraction of effective components in the production of ointment. The soaking and extraction mechanism 100 is used for soaking and extracting Chinese medicinal materials in an extractant, while the loading mechanism 200 is used for storing the medicinal materials.

[0051] Specifically, it includes an immersion extraction mechanism 100, comprising an extraction cylinder 101, an immersion cylinder 102 fixed to the top surface of the extraction cylinder 101 and interconnected therewith, a lifting plate 103 disposed inside the extraction cylinder 101, and a stirring shaft 104 disposed inside the immersion cylinder 102. Multiple placement cylinders 102a, which communicate with the interior of the extraction cylinder 101, are fixedly connected to the outer wall of the immersion cylinder 102, and the free ends of the placement cylinders 102a are inclined upwards. It also includes a loading mechanism 200 fitted inside the placement cylinders 102a and used for holding raw materials, with the extraction temperature of the effective components of the raw materials loaded in each loading mechanism 200 increasing from bottom to top.

[0052] This design allows for high-temperature soaking and extraction of medicinal materials in each loading mechanism 200 sequentially from bottom to top as the extractant moves upward, thereby achieving targeted and effective extraction of active ingredients as the temperature of the extractant increases. Preferably, multiple placement cylinders 102a evenly distributed along the circumference of the soaking cylinder 102 are arranged in an array along the axial direction of the soaking cylinder 102. This design allows medicinal materials with small temperature differences to be placed in multiple placement cylinders 102a within the same group, while medicinal materials with larger temperature differences are placed in placement cylinders 102a in different groups. Figure 9 As shown in scenario I.

[0053] The inner wall of the extraction cylinder 101 is fixed with a guide rib 101b along the vertical direction, which fits against the side wall of the lifting plate 103, so as to limit and guide the movement of the lifting plate 103. At the same time, the lifting plate 103 is also screwed with a screw post 103b arranged in the vertical direction. The upper end of the screw post 103b passes through and extends to the top of the extraction cylinder 101 and is embedded in the output end of the first motor 103b-1. The first motor 103b-1 is fixedly installed on the top surface of the extraction cylinder 101. An electric heating group 103c is fixed in the lifting plate 103. The electric heating group 103c is used to heat the extract. A limiting groove 103d is opened along the circumferential direction on the side wall of the lifting plate 103, and a sealing ring 103d-1 is fitted in the limiting groove 103d with a gap, thereby improving the sealing performance between the lifting plate 103 and the extraction cylinder 101.

[0054] A cover plate 102b is provided above the soaking cylinder 102, and the cover plate 102b is fixed to the flange ring 102e on the outer wall of the soaking cylinder 102 by fixing bolts to achieve a detachable connection between the cover plates 102b. The stirring shaft 104 is rotatably sleeved on the cover plate 102b, and stirring blades 104a are fixedly arranged in an array along the axial direction on the stirring shaft 104 located inside the soaking cylinder 102. The upper end of the stirring shaft 104 is embedded in the output end of the second motor 104b, and the second motor 104b is fixedly installed on the top surface of the cover plate 102b.

[0055] In use, the above-mentioned setup allows the screw column 103b to rotate via the operation of the first motor 103b-1, thereby enabling the lifting plate 103 to move vertically. The extract above the lifting plate 103 will also move vertically accordingly, thus achieving targeted soaking and extraction of the medicinal materials. During the extraction process, the stirring shaft 104 drives the stirring blade 104a to rotate via the operation of the second motor 104b, thereby mixing the extracted active ingredients.

[0056] Furthermore, an output pipe 101a is fixedly provided at the upper end of the outer wall of the extraction cylinder 101. The output pipe 101a is used to discharge the effective components after they have been mixed by soaking. The other end of the output pipe 101a is connected to a concentration device and equipped with a pump body. A switch valve 101a-1 is fixedly installed on the output pipe 101a to realize the opening and closing of the switch valve 101a-1. A stop plate 103a is fixedly provided on the top surface of the lifting plate 103 for fitting against the inside of the soaking cylinder 102. The setting of the stop plate 103a can effectively realize the discharge of the effective components from the delivery pipe 101a.

[0057] Furthermore, a filter plate 102d is provided at the lower end of the interior of the soaking cylinder 102. The filter plate 102d can filter the extract after extraction is completed. A first limiting ring 102c is fixed on the inner wall of the soaking cylinder 102 below the filter plate 102d, and the first limiting ring 102c and the filter plate 102d are fixed together by fixing bolts.

[0058] In addition, it should be noted that this device also includes a controller (not shown in the attached drawings) for controlling various electrical components, and the controller is located in a position convenient for operators to operate.

[0059] Example 5

[0060] Reference Figure 9 This is the fifth embodiment of the present invention. This embodiment is based on the fourth embodiment. The difference is that, under the premise of ensuring that the extraction temperature of the effective components of the raw materials loaded in each loading mechanism 200 increases from bottom to top, another arrangement of the placement cylinder 102a on the soaking cylinder 102 is disclosed.

[0061] Specifically, the axial length of multiple placement cylinders 102a in the same group gradually increases or decreases. This design allows for adjustments to the axial length, ensuring that the free ends of the placement cylinders 102a are tilted upwards. This means that even when multiple placement cylinders 102a in the same group are soaking in the extract, the liquid levels will not be the same, thus enabling the placement of medicinal materials according to different extraction temperatures. Figure 9 As shown in scenario II.

[0062] Example 6

[0063] Reference Figure 9 This is the sixth embodiment of the present invention. This embodiment is based on the fourth embodiment. The difference is that, under the premise of ensuring that the extraction temperature of the effective components of the raw materials loaded in each loading mechanism 200 increases from bottom to top, another arrangement of the placement cylinder 102a on the soaking cylinder 102 is disclosed.

[0064] Specifically, multiple placement cylinders 102a are arranged spirally upwards or downwards along the axis of the soaking cylinder 102. This ensures that each placement cylinder 102a has a different height in the vertical direction, thereby allowing for the placement of medicinal materials according to different extraction temperatures. Figure 9 As shown in scenario III.

[0065] Example 7

[0066] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 This is the seventh embodiment of the present invention. This embodiment is based on any one of the embodiments 4, 5 and 6. The difference is that, in order to better implement the device, the structure of the loading mechanism 200 is described in detail.

[0067] Specifically, the loading mechanism 200 includes a container cylinder 201 sleeved in the placement cylinder 102a, an end cap 202 disposed at the free end of the placement cylinder 102a, and a screw rod 203 coaxially disposed in the container cylinder 201. Multiple connecting sleeves 203c are arrayed along the axial direction on the screw rod 203, and crushing blades 203c-1 are fixedly disposed on the sidewalls of the connecting sleeves 203c. One end of the screw rod 203 is fixedly provided with a protruding block 203b that engages with a limiting hole 201c on the inner wall of the container cylinder 201. Meanwhile, a rectangular... The groove 203e has a drive column 202b slidably sleeved on the end cover 202. One end of the drive column 202b is fixed with a rectangular block 202b-3 that fits with the rectangular groove 203e with a clearance. The other end of the drive column 202b is fixed with a rotating handle 202b-1. In actual use, the rotating handle 202b-1 can be replaced by a drive motor. The end and side wall of the container cylinder 201 are provided with an array of soaking holes 201a. The soaking holes 201a are used for the extract to be immersed in the container cylinder 201, thereby realizing the soaking of the medicinal materials in the container cylinder 201.

[0068] A third limiting ring 201b is fixed on the outer wall of the open end of the container 201 to fit against the free end of the placement cylinder 102a. An external thread 102a-2 is provided on the outer wall of the free end of the placement cylinder 102a to screw into the internal thread 202c on the inner wall of the end cover 202, thereby realizing the fixed fit between the placement cylinder 102a and the end cover 202. A second limiting ring 102a-1 is fixedly sleeved on the outer wall of the placement cylinder 102a to fit against the end of the end cover 202, thereby limiting the fit between the placement cylinder 102a and the end cover 202. At the same time, a fourth limiting ring 202e is fixed on the inner wall of the end cover 202 to fit against the third limiting ring 201b, thereby limiting the position of the container 201 in the placement cylinder 102a.

[0069] In use, the operator first inserts the convex block 203b into the limiting hole 201c, then places the medicinal materials into the holding cylinder 201. After filling the medicinal materials, the operator inserts the holding cylinder 201 into the placement cylinder 102a, and finally fits the rectangular block 202b-3 into the rectangular groove 203e. By rotating the end cap 202, the end cap 202 is fitted into the placement cylinder 102a. While the medicinal materials are soaking in the holding cylinder 201, the operator can rotate the rotating handle 202b-1 to drive the drive column 202b to drive the screw rod 203 to rotate, which in turn rotates the pulverizing blade 203c-1 on the connecting sleeve 203c to cut and pulverize the medicinal materials, thereby improving the extraction of the effective components in the medicinal materials.

[0070] In addition, it should be noted that in actual use, the container 201 is not limited to being filled with the same kind of medicinal material. Different kinds of medicinal materials with small weight parts and small differences in extraction temperature can be placed together in the same container 201.

[0071] Furthermore, a sealing ring 202b-2 is fixedly sleeved on the drive column 202b, and a sealing groove 202d is provided on the end cover 202 for clearance fit of the sealing ring 202b-2, thereby achieving a sealing fit between the drive column 202b and the end cover 202.

[0072] Example 8

[0073] Reference Figure 5 , Figure 6 and Figure 8 This is the eighth embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that in order to fully extract the effective components of the medicinal materials by compression after the extraction of the medicinal materials is completed, thereby improving the effective utilization rate of the medicinal materials, this embodiment is proposed.

[0074] Specifically, a pressure plate 204 is slidably sleeved on a screw rod 203 inside the open end of the container cylinder 201, and a threaded sleeve 204a is fixedly sleeved on the screw rod 203 on one end face of the pressure plate 204; a positioning groove 203a is opened on the side wall of the screw rod 203 along the axial direction, and a positioning strip 203c-2 for clearance matching with the positioning groove 203a is fixed on the inner wall of the connecting sleeve 203c. In this way, the connecting sleeve 203c can be positioned at the upper limit of the screw rod 203, and the connecting sleeve 203c can also move in the axial direction of the screw rod 203. A spring 203d is slidably sleeved on the screw rod 203 between two adjacent connecting sleeves 203c. The spring 203d can realize the reset of the connecting sleeve 203c, and multiple connecting sleeves 203c are located between the pressure plate 204 and the convex block 203b.

[0075] A linkage plate 204b is provided on the side of the pressure plate 204 near the end sleeve cover 202. Limiting posts 204b-1 are symmetrically fixed at both ends on one side of the linkage plate 204b, and positioning holes 204b-2 are symmetrically opened at both ends on the other side of the linkage plate 204b. The limiting posts 204b-1 are slidably sleeved on the pressure plate 204. Locking bolts 202a are symmetrically spirally sleeved on the end sleeve cover 202 for spirally inserting into the positioning holes 204b-2.

[0076] In use, after the Chinese herbal medicine has been soaked and extracted, the operator rotates the locking bolt 202a to screw one end of the locking bolt 202a into the positioning hole 204b-2. The linkage plate 204b is then fixed, thus limiting the pressure plate 204 by the limiting post 204b-1. Under this limiting action, as the screw rod 203 rotates, the threaded sleeve 204a moves the pressure plate 204 along the axis of the screw rod 203. The movement of the threaded sleeve 204a compresses the connecting sleeve 203c. With the help of the spring 203d, multiple connecting sleeves 203c can move along the screw rod 203, allowing the pressure plate 204 to compress the herbs in the container 201, thereby extracting the effective components.

[0077] Additionally, it should be noted that components not described in detail in this article are existing technologies.
