Description

Technical Field

[0001] This utility model belongs to the technical field of medicated patch production equipment, specifically relating to a medicated plaster feeding and supply device suitable for medicated patch production lines. Background Technology

[0002] Traditional Chinese medicine patches are a drug delivery system that delivers medication through the skin. Typically, a traditional Chinese medicine ointment, made from decocted herbs, is squeezed onto a patch carrier (such as between an adhesive backing and release paper). This allows the drug to be released over a long period of time, achieving a sustained therapeutic effect.

[0003] In existing technologies, medicated patch production equipment typically includes an ointment extrusion structure to quantitatively extrude ointment onto the adhesive backing. A hopper is usually connected to the top of the extrusion structure to store the ointment. However, for ointments with poor flowability, the ointment cannot flow downwards on its own in the hopper, leading to material interruptions in the extrusion structure. This results in medicated patches failing to produce properly, leading to poor production efficiency and limited practicality. Utility Model Content

[0004] This utility model provides a medicated plaster feeding device suitable for medicated plaster production lines, which aims to solve the problem of poor practicality caused by the inability of existing medicated plaster feeding devices to adapt to medicated plasters with poor flowability.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a medicated plaster feeding and supply device suitable for a medicated plaster production line, comprising:

[0006] The extrusion assembly is fixed on the medicated patch production device and has a feed inlet and an extrusion outlet corresponding to the adhesive backing fabric.

[0007] The storage bin is fixed on the extrusion assembly, has a storage cavity, and has an outlet at the bottom that communicates with the storage cavity, and a feeding port at the top.

[0008] A pressurizing structure is provided on the storage silo and has a piston part that can extend into the storage silo through the feeding port. The pressurizing structure is used to push the ointment in the storage chamber through the piston part, so that the ointment enters the extrusion assembly.

[0009] In one possible implementation, the booster structure includes:

[0010] A fixed frame is fixed to the storage silo and has an installation platform located above the feeding port;

[0011] A telescopic structure, fixedly mounted on the mounting platform, has a telescopic end facing the feeding port;

[0012] A push plate is fixed on the telescopic end and is adapted to the storage cavity; the push plate is the piston part.

[0013] In one possible implementation, the storage bin has a cylindrical shape.

[0014] In one possible implementation, the extrusion assembly includes an auger fixed to the patch production device, the auger having an inlet and an outlet; the inlet of the auger is the feed port, and the outlet of the auger is the extrusion port.

[0015] In one possible implementation, the extrusion assembly further includes a heating structure comprising a plurality of electrically heated elements spaced apart at the feed inlet.

[0016] In one possible implementation, the bottom of the storage bin is bolted to the auger.

[0017] In this implementation, the storage bin on the extrusion assembly ensures the storage of the ointment, while the pressurization structure pushes the material in the storage chamber through the piston, ensuring that the ointment with poor flowability can descend in time and be replenished into the extrusion assembly, avoiding material interruption. It is highly adaptable, can ensure the stable production of medicated patches, and is highly practical. Attached Figure Description

[0022] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Please refer to the following: Figure 1 and Figure 2The present invention provides a medicated plaster feeding device suitable for medicated plaster production lines. The medicated plaster feeding device includes an extrusion assembly 10, a storage hopper 20, and a pressurizing structure 30. The extrusion assembly 10 is fixed to the medicated plaster production device and has an inlet and an extrusion port corresponding to the adhesive backing. The storage hopper 20 is fixed to the extrusion assembly 10, has a storage chamber, an outlet at the bottom communicating with the storage chamber, and a feeding port at the top. The pressurizing structure 30 is disposed on the storage hopper 20 and has a piston portion that extends into the storage hopper 20 through the feeding port. The pressurizing structure 30 can push the medicated plaster in the storage chamber through the piston portion, causing the medicated plaster to enter the extrusion assembly 10.

[0024] Compared with the prior art, the ointment feeding device for the medicated patch production line provided in this embodiment can ensure the storage of ointment through the storage bin 20 set on the extrusion assembly 10, and the pressure boosting structure 30 can push the material in the storage chamber through the piston part, ensuring that the ointment with poor flowability can descend in time and be replenished into the extrusion assembly 10, avoiding material interruption. It has strong adaptability, can ensure the stable production of medicated patches, and has strong practicality.

[0025] In some embodiments, the above-described booster structure 30 may employ, as follows: Figure 1 The structure shown. See also Figure 1 The pressurization structure 30 includes a fixed frame 31, a telescopic structure 32, and a pusher plate 33. The fixed frame 31 is fixed to the storage hopper 20 and has an installation platform located above the feeding port. The telescopic structure 32 is fixed to the installation platform and has a telescopic end facing the feeding port. The pusher plate 33 is fixed to the telescopic end and is adapted to the storage chamber. The pusher plate 33 is a piston portion.

[0026] The fixed frame 31 can ensure the support of the telescopic structure 32, thereby ensuring the stability of the telescopic structure 32, and at the same time ensuring the pushing force of the push plate 33.

[0027] In this embodiment, the fixed frame 31 may include a base plate, a top plate, and columns. The base plate may be fixedly installed at the bottom of the storage silo 20 or fixedly connected to the extrusion assembly 10, while the top plate is located above the storage silo 20 and is fixedly connected to the base plate through multiple columns to form the fixed frame 31 structure. The top plate can serve as an installation platform for the telescopic structure 32 to be fixedly installed, and the telescopic structure 32 may be a cylinder.

[0028] In some embodiments, the storage silo 20 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 The storage hopper 20 has a cylindrical shape, which facilitates manufacturing. It also involves the adaptation of the push plate 33 and the storage cavity. The push plate 33 also needs to be made into a circular plate for easy manufacturing and to ensure a sealed sliding connection between the two, which can ensure the extrusion effect.

[0029] In some embodiments, the extrusion assembly 10 may employ, as shown in the following examples: Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 The extrusion assembly 10 includes an auger 11, which is fixed on the patch production device. The auger 11 has an inlet and an outlet. The inlet of the auger 11 is the feed inlet, and the outlet of the auger 11 is the extrusion outlet.

[0030] The screw conveyor 11 ensures precise material extrusion, thereby guaranteeing the production effect of the medicated patch.

[0031] In this embodiment, the auger 11 may include a hopper connected to the storage bin 20, a cylinder connected and communicating with the hopper, spiral blades penetrating the hopper and the cylinder, a rotating shaft for winding the blades, and a driver for driving the rotating shaft. See [reference needed]. Figure 2 This technology is existing technology and will not be described in detail here.

[0032] In some embodiments, the extrusion assembly 10 may employ, as shown in the following examples: Figure 2 The structure shown. See also Figure 2 The extrusion assembly 10 also includes a heating structure, which includes a plurality of electric heating elements 12 spaced apart at the feed inlet.

[0033] The electric heating element 12 can ensure that the ointment entering the screw conveyor 11 is preheated, increasing its fluidity and reducing the power consumption of the screw conveyor 11.

[0034] It should be noted that the electric heating element 12 can be ceramic heating, and its set temperature should be such that it does not affect the ointment.

[0035] In some embodiments, the storage silo 20 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 The bottom of the storage silo 20 is bolted to the auger 11. Specifically, a flange connection surface can be set at the feed inlet of the auger 11 and bolted to the flange surface at the bottom of the storage silo 20. This facilitates disassembly and assembly while ensuring locking strength.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
