Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of production equipment for traditional Chinese medicine plasters, specifically to an automatic opening and closing storage container for a traditional Chinese medicine plaster preparation machine. Background Technology
[0002] With the continuous development of medicine, the use of traditional Chinese medicine (TCM) is becoming increasingly widespread, encompassing both external and internal applications. TCM medicated plasters are a common method of external application, enabling precise treatment while being portable and convenient for on-the-go application. Daily-use medicated plasters typically consist of three layers: a bottom layer supporting the plaster (usually non-woven fabric); a middle layer of the plaster itself, often containing a binder; and an top protective film to ensure the plaster's cleanliness before use. To use, the top protective film is peeled off, and the adhesive plaster is then applied directly to the body.
[0003] Traditional Chinese medicine (TCM) treatment principles have always followed the principle of "one prescription, one medicine for one disease." After a TCM doctor prescribes a unique formula based on individual symptoms, a customized plaster is made on-site to match the patient's condition. To improve the efficiency of plaster production, plaster manufacturing equipment has emerged on the market. Before making the plaster, the medicinal materials must first be placed in a storage container and stirred to ensure the overall efficacy of the plaster. After stirring, a specified amount of the plaster needs to be squeezed from the storage container onto a support, laying the foundation for subsequent plaster production. To accommodate different processing steps, a discharge port is set at the bottom of the storage container, which is closed during stirring and opened during squeezing. The opening and closing of the discharge port are all done manually, which is cumbersome and inefficient, failing to meet user needs and hindering product competitiveness. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides an automatic opening and closing storage container for a traditional Chinese medicine plaster preparation machine, which solves the problem of low processing efficiency caused by the discharge port structure of the storage container in the existing traditional Chinese medicine plaster production equipment.
[0005] This utility model discloses an automatic opening and closing storage container for a traditional Chinese medicine plaster preparation machine, comprising a storage container body and an automatic opening and closing assembly. The storage container body has a discharge port at its lower end. The automatic opening and closing assembly includes a connecting cylinder, a piston, and a piston elastic reset component. A discharge channel is provided inside the connecting cylinder, with one end of the discharge channel connected to the discharge port. The piston is positioned within the discharge channel, and a material flow channel is provided inside the piston. An inlet is located on the side of the piston, connected to the material flow channel. The piston elastic reset component allows the inlet to be positioned within the discharge channel without external force acting on the piston. The inner wall of the discharge channel seals the inlet. The piston can move linearly within the discharge channel, enabling the inlet to connect with the storage container body for material discharge.
[0006] This utility model is further improved by using a piston elastic reset component as a reset spring. A limiting boss that cooperates with the lower end of the reset spring is provided on the outer side of the piston component, and a positioning groove that cooperates with the upper end of the reset spring is provided inside the connecting cylinder. The upper and lower ends of the reset spring are respectively limited by the positioning groove and the limiting boss.
[0007] This utility model is further improved by providing a bottom shell at the lower end of the connecting cylinder, and a limiting flange that cooperates with the limiting boss on the bottom shell. The limiting flange can cooperate with the limiting boss to prevent the piston from disengaging from the connecting cylinder.
[0008] This utility model is further improved by providing a movable lifting cavity that cooperates with the limiting boss at the lower end of the discharge channel inside the connecting cylinder, and a positioning step that cooperates with the lower end of the discharge channel on the piston component. The positioning step can cooperate with the lower end surface of the discharge channel to limit the height of the piston component's rise.
[0009] This utility model is further improved by providing an upper sealing ring on the piston component. The upper sealing ring can cooperate with the inner wall of the discharge channel to improve the sealing of the movable lifting chamber.
[0010] This utility model is further improved by providing a lower sealing ring at the lower end of the piston component.
[0011] This utility model is further improved by providing a feed inlet that penetrates both sides of the piston component.
[0012] This utility model is further improved by providing a mounting boss at the upper end of the connecting cylinder, which is located in the discharge port. The mounting boss can improve the positional stability between the connecting cylinder and the main body of the storage container.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an automatic opening and closing storage container for a traditional Chinese medicine plaster preparation machine. Its structure effectively solves the problem of low processing efficiency in the discharge port structure of existing traditional Chinese medicine plaster production equipment. Through the setting of the piston and piston elastic reset component, the automatic opening and closing of the discharge port can be achieved efficiently. When the main body of the storage container is installed, the piston is lifted, and the inlet moves into the main body of the storage container, allowing for extrusion. When the main body of the storage container is removed, the piston elastic reset component drives the piston to reset, eliminating the need for manual intervention. This effectively improves processing efficiency, meets user needs, and enhances product competitiveness. Attached Figure Description

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0021] like Figure 1-3 As shown, this utility model discloses an automatic opening and closing storage container for a traditional Chinese medicine plaster preparation machine, comprising a storage container body 1 and an automatic opening and closing assembly. The storage container body 1 has a discharge port 11 at its lower end. The automatic opening and closing assembly includes a connecting cylinder 2, a piston 3, and a piston elastic reset component 4. The connecting cylinder 2 has a discharge channel 21, one end of which is connected to the discharge port 11. The piston 3 is disposed in the discharge channel 21, and a material flow channel 31 is disposed inside the piston 3. The piston 3 also has a material inlet 32 on its side, which is connected to the material flow channel 31. The piston elastic reset component 4 can ensure that the material inlet 32 is disposed in the discharge channel 21 without external force acting on the piston 3. The inner wall of the discharge channel 21 can seal the material inlet 32. The piston 3 can move linearly in the discharge channel 21, and the linear movement of the piston 3 can enable the material inlet 32 to communicate with the storage container body 1 for material discharge.
[0022] By setting up piston 3 and piston elastic reset 4, the automatic opening and closing of the discharge port 11 can be realized efficiently. When the storage container body 1 is installed, piston 3 is lifted and the inlet 32 moves into the storage container body 1, so that the material can be squeezed out. When the storage container body 1 is removed, piston elastic reset 4 drives piston 3 to reset. No manual intervention is required, which effectively improves the processing efficiency, meets the user's needs, and helps to improve the competitiveness of the product.
[0023] During the pressing process, the press head of the traditional Chinese medicine plaster preparation machine will extend into the main body of the storage container 1. The ointment will enter the material passage 31 from the inlet 32 and finally reach the support body below the main body of the storage container 1.
[0024] The piston elastic reset component 4 is a reset spring. The piston component 3 has a limiting boss 33 on its outer side that cooperates with the lower end of the reset spring. The connecting cylinder 2 has a positioning groove 22 that cooperates with the upper end of the reset spring. The upper and lower ends of the reset spring are limited by the positioning groove 22 and the limiting boss 33, respectively.
[0025] By setting a return spring, the piston 3 can be controlled to return to its original position efficiently.
[0026] The lower end of the connecting cylinder 2 is provided with a bottom shell 5, and the bottom shell 5 is provided with a limiting flange 51 that cooperates with the limiting boss 33. By setting the limiting flange 51, it can effectively cooperate with the limiting boss 33 to prevent the piston 3 from disengaging from the connecting cylinder 2.
[0027] The connecting cylinder 2 has a movable lifting cavity 23 that cooperates with the limiting boss 33 at the lower end of the discharge channel 21. The piston 3 has a positioning step 34 that cooperates with the lower end of the discharge channel 21. The positioning step 34 can cooperate with the lower end surface of the discharge channel 21 to limit the height of the piston 3.
[0028] The piston component 3 is also fitted with an upper sealing ring 35, which can cooperate with the inner wall of the discharge channel 21 to improve the sealing of the movable lifting chamber 23.
[0029] The lower end of the piston component 3 is also fitted with a lower sealing ring 36. The lower sealing ring 36 can improve the sealing performance of the connection between the piston component 3 and the discharge valve on the traditional Chinese medicine plaster preparation machine.
[0030] The feed inlet 32 is provided through both sides of the piston component 3, which allows the material to enter the material conveying channel 31 more quickly.
[0031] The upper end of the connecting cylinder 2 is provided with a mounting boss 24, which is located in the discharge port 11. The mounting boss 24 can improve the positional stability between the connecting cylinder 2 and the main body of the storage container 1.
[0032] As can be seen from the above, the beneficial effects of this utility model are: it can effectively solve the problem of low processing efficiency in the discharge port 11 structure of the storage container in the existing medicated plaster production equipment. By setting the piston 3 and the piston elastic reset component 4, the automatic opening and closing of the discharge port 11 can be realized efficiently. When the storage container body 1 is installed, the piston 3 is lifted and the inlet 32 moves into the storage container body, so that the material can be squeezed out. When the storage container body 1 is removed, the piston elastic reset component 4 drives the piston 3 to reset. No manual intervention is required, which effectively improves the processing efficiency, meets the user's needs, and helps to improve the competitiveness of the product.
