Description

Technical Field

[0001] This utility model relates to the field of production technology of special pads for nuclear magnetic resonance imaging (NMR), specifically a hot pressing device for rapidly cooling special pads for NMR. Background Technology

[0002] With the increasing demand for medical care, higher requirements have been placed on the production efficiency and quality of MRI-specific pads. In the production process of MRI-specific pads, a rapid cooling MRI-specific pad hot pressing equipment is required.

[0003] Most currently used hot pressing equipment cannot cool the mold quickly. During use, the inability to cool the mold rapidly leads to delayed demolding time, reducing the number of products produced per unit time and lowering production efficiency. Furthermore, slow cooling can cause defects such as shrinkage, deformation, and bubbles on the product surface, affecting its appearance and feel, and reducing comfort and quality. This results in poor cooling efficiency and product quality for the hot pressing equipment. Additionally, it is inconvenient to hot press the raw materials for the pads. Insufficient hot pressing leads to incomplete heat pressing, resulting in loose bonding between the layers of material and potential delamination during use. This affects the overall performance and lifespan of the pads, leading to poor production quality for the hot pressing equipment. Utility Model Content

[0004] The purpose of this invention is to provide a rapid cooling thermal pressing device for nuclear magnetic resonance (NMR) pads, in order to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling nuclear magnetic resonance (NMR) dedicated pad hot pressing device, comprising a workbench, a rapid cooling mechanism provided on the top of the workbench, the rapid cooling mechanism comprising a water tank, the water tank being fixedly connected to the top of the workbench, a cover plate being hinged to the top of the water tank, a handle being fixedly connected to the top of the cover plate, a water pipe being fixedly connected to one side of the water tank, a water pump being fixedly connected to the outer wall of the water pipe, a valve being fixedly connected to the outer wall of the water pipe, a cooling sleeve being fixedly connected to one end of the water pipe, and a mold being fixedly connected inside the cooling sleeve.

[0006] As a preferred technical solution, the number of water tanks is two, and the two water tanks are symmetrically arranged with the vertical center line of the workbench as the axis of symmetry.

[0007] As a preferred technical solution, the top of the water tank is provided with an opening, the shape and size of which match the shape and size of the cover plate, and the water tank is hinged to the cover plate through the opening.

[0008] As a preferred technical solution, the shape and size of the cooling jacket match the shape and size of the mold, and the shape of the cooling jacket is rectangular.

[0009] As a preferred technical solution, the top of the workbench is fixedly connected to the bottom of the mold, and a support frame is fixedly connected to one side of the workbench.

[0010] As a preferred technical solution, the bottom of the support frame is provided with a hot pressing mechanism, which includes an electric push rod.

[0011] As a preferred technical solution, an electric push rod is fixedly connected to the bottom of the support frame, and a pressure plate is fixedly connected to the bottom end of the electric push rod.

[0012] As a preferred technical solution, a heating element is fixedly connected to the top of the pressure plate, and the pressure plate is rectangular in shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a rapid cooling mechanism, can achieve the effect of rapid cooling of the mold. During use, by starting the water pump, the coolant in the water tank is injected into the cooling jacket, and the coolant in the cooling jacket absorbs the heat of the mold. This can avoid the product demolding time being delayed due to the inability to cool the mold quickly, which would reduce the number of products produced per unit time and reduce production efficiency. Furthermore, slow cooling may cause defects such as shrinkage, deformation, and bubbles on the product surface, affecting the appearance quality and feel of the product, reducing the comfort and quality of the product. This invention ensures the cooling efficiency and product quality of the equipment.

[0015] 2. This utility model, through the setting of the hot pressing mechanism, can facilitate the hot pressing of the raw materials of the pad. During use, by activating the heating element and the electric push rod, the pressure plate is driven to hot press the raw materials. This can avoid insufficient hot pressing due to the inconvenience of hot pressing the raw materials of the pad, which would result in poor bonding between the layers of the pad and easy delamination during use, affecting the overall performance and service life of the pad, thus ensuring the production quality of the equipment.

[0021] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1 As shown, the present invention provides the following technical solution, including a workbench 1, a rapid cooling mechanism 2 on the top of the workbench 1, the top of the workbench 1 being fixedly connected to the bottom of the mold 4, a support frame 5 being fixedly connected to one side of the workbench 1, and a hot pressing mechanism 3 being provided at the bottom of the support frame 5.

[0023] When the hot pressing equipment is needed, cooling preparations must first be made in advance using the rapid cooling mechanism 2. Then, the raw materials for the pad to be hot-pressed are placed layer by layer in the mold 4, and the raw materials are hot-pressed using the hot pressing mechanism 3. After hot pressing, the mold 4 needs to be cooled using the rapid cooling mechanism 2. After cooling, the molded pad can be demolded from the mold 4, thus completing the work.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, a rapid cooling mechanism 2 is provided on the top of the workbench 1. The rapid cooling mechanism 2 includes a water tank 201. The water tank 201 is fixedly connected to the top of the workbench 1. A cover plate 202 is hinged to the top of the water tank 201. A handle 203 is fixedly connected to the top of the cover plate 202. A water pipe 204 is fixedly connected to one side of the water tank 201. A water pump 205 is fixedly connected to the outer wall of the water pipe 204. A valve 206 is fixedly connected to the outer wall of the water pipe 204. One end of the water pipe 204 is fixedly connected to... There is a cooling jacket 207, and a mold 4 is fixedly connected inside the cooling jacket 207. There are two water tanks 201, which are symmetrically arranged about the vertical center line of the workbench 1. The top of the water tank 201 has an opening, the shape and size of which match the shape and size of the cover plate 202. The water tank 201 is hinged to the cover plate 202 through the opening. The shape and size of the cooling jacket 207 match the shape and size of the mold 4, and the shape of the cooling jacket 207 is rectangular.

[0025] Specifically: When the hot pressing equipment is needed, cooling preparations must first be made in advance. This is done by opening the cover plate 202 through handle 203, pouring coolant into the water tank 201, and then closing the cover plate 202. After hot pressing, the mold 4 needs to be cooled. This is done by opening the water pipe 204 through valve 206 and starting the water pump 205. The water pump 205 draws coolant from the water tank 201 into itself through the water pipe 204, and then delivers the coolant from the water pump 205 to the cooling jacket 2 through the water pipe 204. In step 07, the coolant in the cooling jacket 207 rapidly cools the mold 4, allowing the coolant to absorb heat. Then, the right water pipe 204 is opened through the right valve 206, allowing the coolant that has absorbed heat to be discharged into the right water tank 201 for cooling through the right water pump 205. At the same time, the left water tank 201 continues to supply the missing coolant, allowing it to continuously cool the mold 4, thus completing the rapid cooling process. Once cooled, the molded pad can be demolded from the mold 4, thus completing the work.

[0026] like Figure 1 and Figure 4 As shown, a hot pressing mechanism 3 is provided at the bottom of the support frame 5. The hot pressing mechanism 3 includes an electric push rod 301. The electric push rod 301 is fixedly connected to the bottom of the support frame 5. A pressure plate 302 is fixedly connected to the bottom end of the electric push rod 301. A heating element 303 is fixedly connected to the top of the pressure plate 302. The pressure plate 302 is rectangular in shape.

[0027] Specifically: When it is necessary to hot press the raw material of the pad, the raw material of the pad to be hot pressed is placed layer by layer in the mold 4. Then, the heating element 303 heats the pressure plate 302 to a suitable temperature. Then, the electric push rod 301 is started to extend. The electric push rod 301 drives the pressure plate 302 to descend, so that the pressure plate 302, which has been heated to a certain temperature, hot presses the raw material of the pad, thereby completing the hot pressing work.

[0028] The working principle of this utility model is as follows: When the hot pressing equipment is needed, cooling preparations must first be made in advance. At this time, the cover plate 202 is opened by the handle 203, and then coolant is poured into the water tank 201. The cover plate 202 is then closed. The raw material for the pad to be hot-pressed is then placed layer by layer into the mold 4. The heating element 303 heats the pressure plate 302 to a suitable temperature. Then, the electric push rod 301 is activated, causing it to extend and lower the pressure plate 302, allowing the heated pressure plate 302 to hot-press the raw material, thus completing the hot pressing process. After hot pressing, the mold 4 needs to be cooled. At this time, the water pipe 204 is opened by the valve 206, and the hot pressing equipment is activated. Water pump 205 draws coolant from water tank 201 into itself via water pipe 204. The coolant from water pump 205 is then transported to cooling jacket 207 via water pipe 204, allowing the coolant in cooling jacket 207 to rapidly cool mold 4. The coolant absorbs heat. Then, the right water pipe 204 is opened via valve 206 on the right, allowing the cooled coolant, having absorbed heat, to be discharged into water tank 201 on the right via water pump 205. Simultaneously, water tank 201 on the left continues to supply the missing coolant, ensuring continuous cooling of mold 4, thus completing the rapid cooling process. Once cooled, the molded protective pad can be demolded from mold 4, completing the process.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
