Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing devices for hydrogel patches, and particularly to a manufacturing device for hydrogel patches based on traditional Chinese medicine.

Background Art

[0002] A hydrogel patch based on traditional Chinese medicine is an external patch made by obtaining effective components or effective parts through processes such as extraction and separation of appropriate traditional Chinese medicines selected based on the theory of traditional Chinese medicine, uniformly mixing them with a hydrogel base material, applying them to a backing material, and adding a protective film. It enables the traditional Chinese medicine components to pass through the skin at a constant rate and enter the body's circulation to achieve systemic or local therapeutic effects. During manufacturing, it is necessary to apply the hydrogel patch, and the applied patch contains more moisture, and the patch must be dried to adjust the moisture content, thereby ensuring its viscosity and stability.

[0003] When using existing drying devices for hydrogel patches, the positions of the conveying shaft and the hot air nozzles are fixed, which leads to inconvenience in drying hydrogel patches of different thicknesses, and this may reduce the applicability of the drying device.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In view of the above, the present invention proposes a manufacturing device for hydrogel patches based on traditional Chinese medicine, aiming to solve the problem of insufficient applicability of the drying equipment for hydrogel patches in the current technology.

A second screw rod inserted into the interior of the upright pipe is installed at the output end of the second electric motor. A blower is installed at the upper end of the drying box. The air blowing end of the blower is combined with the transfer pipe via a conduit.

[0008] Both of the first screw rods on the two second rotating shafts have reverse threads. Under the operation of the first electric motor, the two second rotating shafts rotate, whereby the two guide shafts move up and down inside the empty tank. By temporarily adjusting the distance between the two guide shafts, it is convenient to dry gel patches of different thicknesses.

Modes for Carrying Out the Invention

[0020] We will describe the representative embodiments of the present invention in more detail with reference to the drawings. Although the representative embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and is not limited by the embodiments described herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art. It is necessary to clarify that it is possible to combine the embodiments of the present invention with the features in the embodiments when there is no conflict. We will describe the present invention in detail with reference to the drawings and in combination with the embodiments.

[0021] As shown in FIGS. 1-6, the manufacturing apparatus of the hydrogel patch based on traditional Chinese medicine proposed by the present invention includes a drying box 1. An air blowing pipe is provided at the bottom of the drying box 1. Two empty tanks 2 are symmetrically arranged on both the left and right sides of the drying box 1. A plurality of sliding grooves 4 are symmetrically arranged up and down on both the front and rear sides of the empty tank 2. Sliding blocks 3 are slidably arranged inside the sliding grooves 4 respectively. A guide shaft 5 is rotatably arranged between the two sliding blocks 3 arranged front and rear. Two symmetrically arranged sliding blocks 3 are connected via a connecting rod 6. A plurality of connecting rods 6 are respectively located on both the front and rear sides of the drying box 1.

[0022] A box body 7 and a first electric motor 8 are installed on the upper part of the drying box 1. A first rotating shaft 9 is rotatably arranged inside the box body 7. Second rotating shafts 13 are vertically rotatably arranged at both ends of the box body 7. Two reverse-threaded first screw rods 14 are symmetrically arranged at the bottom of the second rotating shaft 13. Then, the two first screw rods 14 penetrate through the two connecting rods 6 respectively. A second driven bevel gear 15 is installed at the upper end of the second rotating shaft 13. Second driving bevel gears 12 meshing with the second driven bevel gear 15 are installed at both ends of the first rotating shaft 9. A first driven bevel gear 10 is installed in the middle part of the first rotating shaft 9. A first driving bevel gear 11 meshing with the first driven bevel gear 10 is installed at the output end of the first electric motor 8.

[0023] A partition plate 20 is provided at the top of the drying box 1. A second electric motor 23 is installed at the upper end of the partition plate 20. An air blowing plate 21 is installed below the partition plate 20. A plurality of air blowing holes are provided at the lower end of the air blowing plate 21. An upright tube 22 and a transfer tube 25 penetrating the partition plate 20 are installed at the upper end of the air blowing plate 21. A second screw rod inserted into the interior of the upright tube 22 is installed at the output end of the second electric motor 23. A blower 16 is installed at the upper end of the drying box 1. The air blowing end of the blower 16 is aligned with the transfer tube 25 through a conduit.

[0024] Both of the first screw rods 14 on the two second rotating shafts 13 are provided with reverse threads. Under the operation of the first electric motor 8, the two second rotating shafts 13 rotate, whereby the two guide shafts 5 move up and down inside the empty tank 2. By temporarily adjusting the distance between the two guide shafts 5, it is convenient for drying gel patches of different thicknesses.

[0025] Under the operation of the second electric motor 23, the second screw rod rotates to adjust the height of the air blowing plate 21.

[0026] In this embodiment, the cross-section of the sliding groove 4 is rectangular.

[0027] In this embodiment, the sliding block 3 is integrated with the connecting rod 6.

[0028] The principle of adjusting the distance between the guide shafts 5 is as follows. When the first electric motor 8 starts, under the drive of the first driving bevel gear 11 at the output end of the first electric motor 8, the first driven bevel gear 10 in the middle of the first rotating shaft 9 rotates, thereby causing the first rotating shaft 9 to rotate. The two second driving bevel gears 12 at both ends of the first rotating shaft 9 mesh with the two second driven bevel gears 15 at the upper end of the second rotating shaft 13, thereby causing the second rotating shaft 13 to rotate. The two first screw rods 14 symmetrically arranged at the bottom of the second rotating shaft 13 have reverse threads and penetrate through the two connecting rods 6 respectively. Therefore, when the second rotating shaft 13 rotates, the two first screw rods 14 can rotate synchronously, causing the two connecting rods 6 to move oppositely on the first screw rods 14, and then moving the two symmetrically arranged sliding blocks 3, and finally causing the two guide shafts 5 to move up and down to achieve the purpose of adjusting the distance between the guide shafts 5.

[0029] The principle of adjusting the height of the air blowing plate 21 is as follows. When the second electric motor 23 starts, the second screw rod at the output end of the second electric motor 23 rotates inside the vertical pipe 22. Since the second screw rod is screwed with the vertical pipe 22, the air blowing plate 21 moves up and down along the direction of the guide rod 24, thereby adjusting the height of the air blowing plate 21.

[0030] The drying principle is as follows. The blower 16 sucks air through the air inlet pipe 17. After the air is filtered by the filter plate 18, it is sent through the conduit from the air blowing end of the blower 16 to the transfer pipe 25, and then blown out from a plurality of air blowing holes at the lower end of the air blowing plate 21, thereby drying the hydrogel patch located on the guide shaft 5 in the drying box 1. The moisture generated during the drying process is discharged through the air blowing pipe at the lower end of the drying box 1.

[0031] 1) Preparation: Check whether all parts of the device are firmly installed. For example, check whether the box body 7 is firmly fixed to the upper end of the drying box 1 with screws, whether the sliding block 3 is integrally connected to the connecting rod 6 and properly connected, and whether the sliding groove 4 fits smoothly with the sliding block 3. Place the hydrogel patch to be dried on the guide shaft 5.

[0032] 2) Adjust the spacing of the guide shafts 5. The first electric motor 8 starts according to the thickness of the hydrogel patch. The first electric motor 8 moves the guide shafts 5 up and down according to the aforementioned working principle, and after adjusting to an appropriate spacing, stop the first electric motor 8.

[0033] 3) Adjust the height of the air outlet plate 21. When the second electric motor 23 starts, the second electric motor 23 moves the air outlet plate 21 for vertical movement adjustment, so that after the air outlet plate 21 reaches the designated height and the hot air is adjusted to an appropriate height for evenly blowing on the hydrogel patch, stop the second electric motor 23.

[0034] 4) Drying operation: When the blower 16 starts, the blower 16 blows the air filtered by the filtration assembly 18 into the drying box 1 to dry the hydrogel patch during the conveying process. During the drying process, the drying status can be seen through the observation window.

[0035] 5) Completion: After drying is completed, first stop the blower 16, and then remove the dried hydrogel patch from the guide shafts 5.

[0036] Under the drive of the first electric motor 8, the first rotating shaft 9, the second rotating shaft 13 and the first screw rod 14 are interlocked to temporarily adjust the spacing between the two guide shafts 5, thereby enabling the manufacturing device to dry gel patches of different thicknesses, greatly improving the applicability of the device, and solving the problem that the applicability is poor due to the fixed position of the conveying shaft in the existing equipment.

[0037] In this embodiment, a guide rod 24 penetrating the partition plate 20 is installed at the upper end of the air outlet plate 21.

[0038] The guide rod 24 penetrating the partition plate 20 is installed at the upper end of the air outlet plate 21, and during the process of moving the air outlet plate 21 up and down to adjust the height, the stability of the air outlet plate 21 can be ensured, the sway of the air outlet plate 21 can be avoided, so that the hot air blows on the hydrogel patch more evenly and stably, and the drying effect is improved.

[0039] In this embodiment, an air blowing pipe 17 is installed at the air blowing end of the blower 16, a filter plate 18 is installed inside the air blowing pipe 17, an annular frame 19 is further installed inside the air blowing pipe 17, the filter plate 18 is fixed inside the annular frame 19, and in addition, the annular frame 19 is screwed with the air blowing pipe 17.

[0040] A filter plate 18 is arranged in the air blowing pipe 17 at the air blowing end of the blower 16, and by screwing the filter plate 18 with the air blowing pipe 17 through the annular frame 19, it is convenient for switching. The filter plate 18 can filter impurities in the air and prevent the impurities from being blown onto the hydrogel patch, thereby improving the drying quality of the hydrogel patch.

[0041] In this embodiment, the box body 7 is fixed to the upper end of the drying box 1 with screws.

[0042] By fixing the box body 7 to the upper end of the drying box 1 with screws, it is easy to install and remove, which is convenient for inspection and maintenance inside the equipment. Moreover, the sliding groove 4 has a rectangular cross-section and stably fits with the sliding block 3, and by integrating the sliding block 3 with the connecting rod 6, the stability of the equipment structure is improved, the failure rate is reduced, and the maintenance cost is lowered.

[0043] In this embodiment, both the first electric motor 8 and the second electric motor 23 are servo motors.

[0044] Since both the first electric motor 8 and the second electric motor 23 are servo motors, it is possible to achieve precise rotational speed and position control. By adjusting the distance between the guide shafts 5 and the height of the air outlet plate 21, it can reach the required position more precisely, so as to improve the operation accuracy and production efficiency of the equipment.
