Description

Technical Field

[0001] This utility model relates to the field of heat-reducing patch processing technology, specifically a hydrogel heat-reducing patch shaping device. Background Technology

[0002] Hydrogel fever-reducing patches, as a common physical cooling medical device, are widely used in scenarios such as children's fever care, local cooling in adults, and postoperative fever reduction due to their advantages of convenient use, gentle cooling, and high safety. Their core structure typically includes a base layer, a hydrogel drug layer supported on the base layer, and a protective film covering the surface of the hydrogel layer. The molding quality of the hydrogel layer directly affects the patch's fit, drug release efficiency, and user experience. Therefore, the molding and finishing processes of the hydrogel layer are crucial in the automated production of fever-reducing patches.

[0003] Currently, the industrial production of hydrogel heat-reducing patches mostly employs continuous coating or drip-casting processes. This involves transferring the prepared hydrogel slurry to the surface of a non-woven fabric base layer via a specific conveying mechanism, followed by subsequent curing, cutting, and encapsulation processes to complete the finished product. However, in actual production, due to the inherent fluidity and viscosity of the hydrogel slurry, after it falls onto or is coated onto the non-woven fabric surface, it is easily affected by factors such as uneven gravity distribution, vibration of the conveying mechanism, and fluctuations in the slurry dripping speed. This can easily lead to problems such as unevenness, rough edges, or localized accumulation on the upper surface of the hydrogel layer.

[0004] The aforementioned irregular hydrogel layer formation issue can have several adverse effects on subsequent production processes: First, during the subsequent protective film lamination process, the uneven hydrogel surface can easily lead to the formation of air bubbles between the protective film and the hydrogel layer, which not only affects the product's appearance but may also cause the protective film to detach, reducing the product's packaging seal. Second, if the hydrogel layer thickness is unevenly distributed, it will result in significant differences in the local cooling effect of the fever-reducing patch during use, affecting its clinical efficacy. Third, the irregular hydrogel shape may cause cutting deviations during the cutting process, increasing the scrap rate, reducing production efficiency, and increasing production costs.

[0005] Therefore, it is necessary to provide a hydrogel fever-reducing patch reshaping device to solve the above problems. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the purpose of this utility model is to provide a hydrogel fever-reducing patch shaping device to solve the problems mentioned in the background technology.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a hydrogel heat-reducing patch shaping device for smoothing the upper surface of the hydrogel layer on non-woven fabric, including a transmission platform, a shaping bracket fixedly connected above the transmission platform, and a shaping unit extended and retracted on one side of the shaping bracket in the vertical direction. The shaping unit is located directly above the hydrogel layer and has a positioning cover and a pressure block. The positioning cover has a downward-opening receiving cavity for receiving the hydrogel layer, and the pressure block is slidably installed in the receiving cavity to apply pressure to the upper surface of the hydrogel layer.

[0008] Furthermore, the inner wall material of the cavity is polytetrafluoroethylene.

[0009] Furthermore, the positioning cover has a through hole in the center, the top of the pressure block has a protrusion, and the protrusion has a connecting hole that is concentric with the through hole. A cylinder is fixedly connected to one side of the shaping bracket. The cylinder has a telescopic rod that extends and retracts vertically. The end of the telescopic rod away from the cylinder passes through a through hole and is fixedly connected to a connecting hole. The cylinder drives the positioning cover and the pressure block to slide up and down.

[0010] Furthermore, the bottom of the positioning cover has a slit that gradually slopes from the outside to the inside, and the bottom of the slit intersects with the bottom of the receiving cavity to form a sharp point.

[0011] Furthermore, the pressure block also has a contact portion that is slidably connected within the receiving cavity, and the lower surface of the contact portion is made of polytetrafluoroethylene material.

[0012] Furthermore, a cutting bracket is also installed on the transmission platform. The cutting bracket is located at the front end of the shaping bracket. The cutting bracket has a horizontally arranged columnar rod, on which two cutting blades are slidably connected. The cutting blades are respectively aligned with the sharp parts along the direction of nonwoven fabric movement.

[0013] Furthermore, the cutting blade has a connecting seat and a blade body. The connecting seat is located at the root of the blade body, and a fastening seat is fixedly connected to the connecting seat so that the cutting blade is mounted on the columnar rod.

[0014] Furthermore, the outer surface of the blade body slopes inward from the root, the inner surface of the blade body is aligned with the outer wall of the receiving cavity, and the lower end of the blade body away from the root is an arc-shaped portion.

[0015] Furthermore, the material of the arc-shaped portion is rubber.

[0016] The beneficial effects of this utility model are as follows: The hydrogel cooling patch shaping device provided by this utility model uses a positioning cover and a pressure block installed directly above the non-woven fabric to allow the hydrogel layer to fall into the positioning cover. Then, the pressure block descends to shape the upper surface of the hydrogel layer in the receiving cavity, so that the upper surface of the hydrogel layer forms a plane and the edges are flush, so that the thickness of the hydrogel layer is uniform. This avoids the formation of air bubbles between the protective film and the hydrogel layer due to the uneven hydrogel surface in subsequent operations, which can also lead to large differences in the local cooling effect of the cooling patch during use.

[0017] By incorporating a cutting blade to cut the hydrogel on both sides outside the hydrogel layer, the efficiency of waste disposal is improved, and labor costs in production are saved.

[0018] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0020] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0022] like Figure 1-7 As shown, the present invention provides a technical solution: a hydrogel heat-reducing patch shaping device for flattening the upper surface of the hydrogel layer 81 on the non-woven fabric 8, including a transmission platform 1, a shaping bracket 2 fixedly connected above the transmission platform 1, and a shaping unit extended and retracted on one side of the shaping bracket 2 in the vertical direction. The shaping unit is located directly above the hydrogel layer 81 and has a positioning cover 5 and a pressure block 6. The positioning cover 5 has a downward-facing receiving cavity 501 for receiving the hydrogel layer 81. The pressure block 6 is slidably installed in the receiving cavity 501 to apply pressure to the upper surface of the hydrogel layer 81.

[0023] The inner wall material of the cavity 501 is polytetrafluoroethylene.

[0024] The positioning cover 5 has a through hole 51 in the center, and the top of the pressure block 6 has a protrusion 61, and a connecting hole 611 is provided in the protrusion 61, which is concentric with the through hole 51. A cylinder 4 is fixedly connected to one side of the shaping bracket 2. The cylinder 4 has a telescopic rod 41 that extends and retracts vertically. The end of the telescopic rod 41 away from the cylinder 4 passes through the through hole 51 and is fixedly connected to the connection hole 611. The cylinder 4 drives the positioning cover 5 and the pressure block 6 to slide up and down.

[0025] The bottom of the positioning cover 5 has a slit 52 that gradually slopes from the outside to the inside, and the bottom of the slit 52 intersects with the bottom of the receiving cavity 501 to form a sharp part.

[0026] The pressure block 6 also has a contact portion 62 that is slidably connected within the receiving cavity 501, and the lower surface of the contact portion 62 is made of polytetrafluoroethylene material.

[0027] The transmission platform 1 is also equipped with a cutting bracket 3, which is located at the front end of the shaping bracket 2. The cutting bracket 3 has a horizontally arranged columnar rod 31, on which two cutting blades 7 are slidably connected. The cutting blades 7 are respectively aligned with the sharp parts along the forward direction of the nonwoven fabric 8.

[0028] The cutting blade 7 has a connecting seat 71, a blade body 73 and an arc-shaped part 74. The connecting seat 71 is located at the root of the blade body 73, and a fastening seat 72 is fixedly connected to the connecting seat 71 so that the cutting blade 7 is mounted on the columnar rod 31.

[0029] The outer side of the blade body 73 slopes from the outside to the inside from the root. The inner side of the blade body 73 is aligned with the outer wall of the receiving cavity 501. The lower end of the blade body 73 away from the root is an arc-shaped part 74.

[0030] The material of the curved part 74 is rubber.

[0031] In one embodiment, the device shapes the hydrogel fever-reducing patch.

[0032] Specifically, the connecting seat 71 of the two cutting blades 7 is installed on the column rod 31, the arc-shaped part 74 is oriented toward the shaping bracket 2 and aligned with the bottom end of the cutting part 52, so that the arc-shaped part 74 falls onto the transmission platform 1, the transmission platform 1 including but not limited to a belt conveyor; The nonwoven fabric 8 with the attached hydrogel layer 81 is placed at the end of the transfer platform 1. The transfer platform 1 is started to move the nonwoven fabric 8 forward. When the hydrogel layer 81 moves directly below the positioning cover 5, the telescopic rod 41 of the control cylinder 4 moves downward, the pressure block 6 falls, and the positioning cover 5 also falls due to gravity. When the positioning cover 5 drives the cutting part 52 to fall onto the hydrogel layer 81, the positioning cover 5 is supported by the transfer platform 1. At this time, the hydrogel layer 81 is located in the receiving cavity 501, and a part of the hydrogel layer 81 is isolated outside by the positioning cover 5. As the telescopic rod 41 continues to descend, it causes the pressure block 6 to move downward within the receiving cavity 501. When the telescopic rod 41 reaches the predetermined stroke, the lower surface of the pressure block 6 contacts the upper surface of the hydrogel layer 81. At this time, the upper surface of the hydrogel layer 81 becomes flat after being pressed by the pressure block 6. Subsequently, the telescopic rod 41 moves upward, causing the pressure block 6 to move upward. Since the lower surface of the pressure block 6 and the outer wall material of the receiving cavity 501 are both polytetrafluoroethylene, the hydrogel layer 81 will not stick to its lower surface and can be easily removed from the positioning cover 5. When the upper end of the pressure block 6 contacts the positioning cover 5, it causes the positioning cover 5 to move upward together. At this time, the nonwoven fabric 8 continues to move forward. When it passes the cutting blade 7, the arc-shaped part 74 cuts along the indentation formed on the hydrogel layer 81 by the cutting part 52, so that the hydrogel on both sides of the hydrogel layer 81 is separated from the shaped hydrogel layer 81. Since the material of the arc-shaped part 74 is rubber, the arc-shaped part 74 will not damage the nonwoven fabric 8 during cutting. Then, the separated hydrogel and the hydrogel at the top and bottom ends after shaping are cleaned away manually, and then it can enter the next process to continue shaping the hydrogel layer 81 in the above manner.

[0033] In summary, this device uses a positioning cover 5 and a pressure block 6 installed directly above the nonwoven fabric 8 to allow the hydrogel layer 81 to fall into the positioning cover 5. Then, the pressure block 6 descends to shape the upper surface of the hydrogel layer 81 in the receiving cavity 501, making the upper surface of the hydrogel layer 81 flat and the edges flush. This ensures that the thickness of the hydrogel layer 81 is consistent and avoids the formation of air bubbles between the protective film and the hydrogel layer due to an uneven hydrogel surface in subsequent operations. This also prevents the cooling patch from having large differences in local cooling effect during use.

[0034] By setting up a cutting blade 7 to cut the hydrogel on both sides outside the hydrogel layer 81, the efficiency of waste treatment is improved and labor costs in production are saved.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
