Description

A polymer material heating and pressing device Technical Field

[0001] This utility model relates to the field of polymer material heating and pressing technology, and in particular to a polymer material heating and pressing device. Background Technology

[0002] Functional polymer materials, or simply functional polymers, refer to polymer materials with physical and chemical functions such as optical, electrical, magnetic, acoustic, and thermal properties that can be used in industry and technology. With the rapid development of industry, functional polymer materials are being used more and more frequently in our lives. In the process of producing polymer materials, sometimes it is necessary to process them into tablets. However, before tableting, the polymer materials need to be heated to ensure better tableting.

[0003] A search revealed that patent CN220390121U discloses a heating and pressing device for polymer materials; however, this heating and pressing device has the following shortcomings in use:

[0004] In use, the polymer material is placed in a molding tank and heated, and then pressed into tablets. However, after pressing, the tablet-shaped molecular material remains in the molding tank, making it difficult to remove the tablet-shaped molecular material. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the existing technology where polymer materials are placed in a molding tank for heating and then pressed into tablets. However, after pressing, the sheet-like molecular material remains in the molding tank, making it difficult to remove the sheet-like molecular material. Therefore, this invention proposes a polymer material heating and pressing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A polymer material heating and tableting device includes a machine base, a support welded to the top of the machine base, a driving component fixedly mounted on the top of the support, a telescopic part of the driving component passing through the top of the support and fixedly mounted on a lower pressure box, a forming box located directly below the lower pressure box, the diameter of the lower pressure box being the same as the inner diameter of the forming box, and a rotating mechanism located on the top of the machine base. After the polymer material is tableted, the rotating mechanism can flip the forming box to facilitate its unloading.

[0008] In order to cool down the polymer material inside the molding box, the machine also includes a cooling mechanism, which can cool down the polymer material after it is pressed into tablets.

[0009] In one possible design, the rotating mechanism includes two vertical plates and two rotating rods. The bottom of each of the two vertical plates is fixedly connected to the top of the machine base. Bearings are fixedly installed on the sides of the two vertical plates that are close to each other. One end of each of the two rotating rods is fixedly connected to the inner wall of the inner ring of the two bearings. The ends of the two rotating rods that are close to each other are welded to the two sides of the forming box. A handle for personnel to rotate the forming box is fixedly installed on one side of the forming box.

[0010] In one possible design, the cooling mechanism includes a water tank and a water pump. The bottom of the water tank is fixedly connected to the inner wall of the bottom of the machine base, and the bottom of the water pump is also fixedly connected to the inner wall of the bottom of the machine base. A water pump inlet is fixedly provided with a suction pipe, one end of which is fixedly connected to and communicates with one side of the water tank. A first fixed pipe is fixedly provided at the water pump outlet, the top end of which penetrates the top of the machine base. The lower pressure chamber has a hollow internal structure, and a second fixed pipe and a third fixed pipe are respectively fixedly provided on the top of both sides of the lower pressure chamber. The water tank is connected to the second and third fixed pipes, both of which have flexible hoses fixedly installed at their bottom ends. A circulation pipe is installed on one side of the water tank and is connected to it. One end of the circulation pipe passes through the top of the machine. The bottom ends of the two flexible hoses are fixedly connected to the top of the circulation pipe and the top of the first fixed pipe, respectively. A water inlet is provided on the top of the water tank and a cover is placed thereon. A mesh plate is fixedly installed on the bottom inner wall of the water tank. The water tank is divided into an ice block area and a water area by the mesh plate. A drain pipe for easy water replacement is fixedly installed on one side of the water tank, and a valve is installed on the drain pipe.

[0011] In one possible design, the top of the machine tool is slidably connected to a support base for supporting the molding box in a parallel state. An electric push rod for moving the support base is fixedly installed on one side of the support base. The telescopic part of the electric push rod passes through one side of the machine tool and is fixedly connected to one side of the support base.

[0012] In one possible design, an arc-shaped hole is provided on one side of the molding box, and a fixing rod for limiting the rotation angle of the molding box is fixedly provided on one side of one of the vertical plates, with one end of the fixing rod located inside the arc-shaped hole.

[0013] In one possible design, the molding box has a cavity, and a heating element for heating the polymer material is installed in the cavity.

[0014] In one possible design, the bottom of the support base has a notch, and the top of the machine tool is equipped with a collection box for collecting the poured polymer material. The diameter of the collection box is smaller than the inner diameter of the notch and larger than the diameter of the molding box.

[0015] In this application, during use, first add an appropriate amount of water and ice cubes (the ice cubes are located on the left side of the mesh plate) to cool the water. Then, place the cover on the water tank. According to production needs, prepare an appropriate amount of polymer material and add it to the molding box (initially, the support base is located below the molding box; the molding box is horizontal, and the distance between the molding box and the machine is the same as the height of the support base). Start the heating element, which transfers heat to the polymer material inside the molding box for heating. Start the drive element, causing its telescopic part to extend downwards, driving the pressure box downwards. When the pressure chamber comes into contact with the polymer material inside the molding box, the driving component continues to apply pressure, causing the polymer material to be pressed into a sheet shape under the action of the pressure chamber and the molding box. After heating is completed, the power to the heating component is turned off, and the water pump is started. Water from the water tank enters the water pump through the pumping pipe, then flows through the first fixed pipe and the telescopic hose into the hollow structure of the pressure chamber. The water flows inside the pressure chamber, absorbing heat from it, and then returns to the water tank through the second fixed pipe, the third fixed pipe, and another telescopic hose, forming a water circulation. This cools the polymer material inside the molding box. After cooling is completed, the electric motor is started. The push rod extends its telescopic part, pushing the support base to slide on the machine platform, causing the support base to move away from under the forming box. The operator holds the handle on one side of the forming box and slowly rotates it. Due to the limiting effect of the fixing rod within the arc-shaped hole, the forming box can only rotate a certain angle. When it rotates to the appropriate position, the pressed tablets inside the forming box will automatically pour out under gravity and fall into the collection box below the notch at the bottom of the support base on the top of the machine platform (the collection box can also be picked up and used to catch the tablets while the forming box is rotating). After pouring out, the forming box rotates back to its initial position (horizontal position) and is then supported by the support base. The support can be provided, and the heating element can be one of the following: an electric heating plate, an electric heating wire, or an electric heating tube. The driving element can be one of the following: an electric push rod, a cylinder, or a hydraulic cylinder. The specific choice can be made according to actual needs. It should be noted that the electric push rod, driving element, water pump, and heating element require an external controller for control and an external power supply for power. The power supply for the heating element can be provided by drilling a hole in the molding box for wiring. The molding box and the lower pressure box can be made of thermally conductive metal. The specific material can be selected according to needs (the water pump can be turned off when cooling of the polymer material is not required).

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, a polymer material heating and pressing device is provided. By setting up a rotating mechanism, and utilizing the cooperation of a vertical plate, a rotating rod, bearings, and a handle, the forming box can be flipped after pressing. This design cleverly solves the problem in the prior art that sheet-like polymer materials are difficult to remove from the forming tank. The operator only needs to hold the handle and gently rotate the forming box to smoothly pour out the pressed tablets, greatly shortening the tablet removal time and improving production efficiency.

[0018] In this utility model, the polymer material heating and pressing device uses a water circulation system formed by a water tank, a water pump, a fixed pipe, a telescopic hose, and a hollow structure inside the lower pressing chamber to continuously cool the polymer material in the molding box. The water pump draws water from the water tank and delivers it to the lower pressing chamber to absorb the heat generated by pressing the tablets. The water then flows back to the water tank, and this cycle repeats, greatly improving the cooling efficiency and enabling the polymer material to cool and solidify quickly, thus ensuring the quality and stability of the pressed tablets.

[0019] In this invention, the rotating mechanism allows the molding box to be flipped after the tableting is completed, making it easier to pour out the tablets, greatly shortening the tablet removal time and improving production efficiency. The cooling mechanism can cool the polymer material inside the molding box, making it easier for personnel to handle. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Referring to Figures 1-4, a heating and pressing device includes: a machine base 1, a forming box 4, a lower pressing box 5, a rotating mechanism, a cooling mechanism, a support base 3, and related driving and control components. These components work together to achieve heating and pressing of polymer materials into tablets, efficient cooling, and convenient tablet removal. The machine base 1 serves as the supporting foundation for the entire device, with a bracket 6 welded to its top. The bracket 6 provides a fixed mounting position for the driving component 7. The interior of the machine base 1 provides installation space for the water tank 13 and water pump 8 of the cooling mechanism. Additionally, a sliding track (not shown in the figures) for the support base 3 is provided on the top of the machine base 1, facilitating the sliding of the support base 3 under the drive of the electric push rod 19.

[0028] The forming box 4 is positioned directly below the pressure chamber 5. The diameter of the pressure chamber 5 is the same as the inner diameter of the forming box 4, ensuring that the pressure chamber 5 can accurately enter the forming box 4 during the tableting process, applying uniform pressure to the polymer material. The forming box 4 has a cavity inside, within which a heating element is installed. The heating element can be any of an electric heating plate, heating wire, or electric heating tube, selected according to actual production needs. The heating element is powered by an external power supply, and holes can be made in the forming box 4 for wiring connections. This allows the polymer material placed inside the forming box 4 to be heated to a temperature suitable for tableting. The pressure chamber 5 has a hollow interior structure for circulating cooling water to cool the polymer material after tableting.

[0029] The rotating mechanism includes two vertical plates 14 and two rotating rods 17. The bottom of both vertical plates 14 is fixedly connected to the top of the machine base 1, and bearings are fixedly installed on the sides of the vertical plates 14 that are close to each other. One end of each of the two rotating rods 17 is fixedly connected to the inner wall of the inner ring of the two bearings, and the other end is welded to both sides of the forming box 4. This connection method allows the forming box 4 to rotate around the rotating rods 17.

[0030] A handle 15 is fixedly provided on one side of the molding box 4. The operator can rotate the molding box 4 by holding the handle 15 to realize the tablet rewinding operation after pressing.

[0031] In addition, an arc-shaped hole is provided on one side of the molding box 4, and a fixing rod 16 is fixedly installed on one side of one of the vertical plates 14, with one end of the fixing rod 16 located inside the arc-shaped hole. When the molding box 4 is rotated, the fixing rod 16 moves within the arc-shaped hole, limiting the rotation angle of the molding box 4, preventing the molding box 4 from overturning, and ensuring the stability and safety of the device.

[0032] The cooling mechanism includes a water tank 13 and a water pump 8. The bottom of the water tank 13 is fixedly connected to the inner wall of the bottom of the machine base 1. The top of the water tank 13 has a water inlet and a cover for adding water and ice. A mesh plate 18 is fixedly installed on the inner wall of the bottom of the water tank 13, dividing the water tank 13 into an ice zone and a water zone. Ice is placed in the ice zone to cool the water in the water zone. A drain pipe with a valve is also provided on one side of the water tank 13 for easy water replacement, allowing water to be drained from the water tank 13.

[0033] The bottom of the water pump 8 is fixedly connected to the inner wall of the bottom of the machine base 1. A water pump pipe is fixedly installed at the inlet of the water pump 8, and one end of the water pump pipe is fixedly connected to one side of the water tank 13. A first fixed pipe 9 is fixedly installed at the outlet of the water pump 8, and the top end of the first fixed pipe 9 passes through the top of the machine base 1. A second fixed pipe 12 and a third fixed pipe 11 are fixedly installed on the top of both sides of the pressure box 5 and are connected to each other. A telescopic hose 10 is fixedly installed at the bottom end of both the second fixed pipe 12 and the third fixed pipe 11. A circulation pipe is installed on one side of the water tank 13 and is connected to each other. One end of the circulation pipe passes through the top of the machine base 1, and the bottom ends of the two telescopic hoses 10 are fixedly connected to the top end of the circulation pipe and the top end of the first fixed pipe 9, respectively.

[0034] After tableting is completed, water pump 8 is started. Water cooled by ice in water tank 13 enters water pump 8 through a pumping pipe, and then enters the hollow structure of lower pressure box 5 through first fixed pipe 9 and telescopic hose 10. The water flows in lower pressure box 5, absorbing the heat generated by tableting, and then returns to water tank 13 through second fixed pipe 12, third fixed pipe 11 and another telescopic hose 10, forming a water circulation, thereby efficiently cooling the polymer material in molding box 4.

[0035] This application is used in the field of heating and pressing polymer materials into tablets, but it can also be used in other fields applicable to this application.

[0036] Example 2

[0037] Referring to Figures 1-4, an improvement upon Example 1 is provided: a polymer material heating and pressing device, which is used in the field of polymer material heating and pressing.

[0038] The support base 3 is slidably connected to the top of the machine base 1 to support the forming box 4 when it is in a parallel and horizontal state, so as to ensure the stability of the forming box 4 during the tableting process.

[0039] An electric push rod 19 is fixedly installed on one side of the bracket 6. The telescopic part of the electric push rod 19 passes through one side of the machine base 1 and is fixedly connected to one side of the support base 3. When it is necessary to flip the molding box 4 to pour out the pressed tablets, the electric push rod 19 is activated, causing its telescopic part to extend and push the support base 3 to slide on the machine base 1, so that the support base 3 moves away from under the molding box 4, providing space for the molding box 4 to flip. After the pressing is completed, the telescopic part of the electric push rod 19 retracts, driving the support base 3 back to under the molding box 4 to support the molding box 4.

[0040] A notch is provided at the bottom of the support base 3, and a collection box 2 is placed on top of the machine base 1. The diameter of the collection box 2 is smaller than the inner diameter of the notch, but larger than the diameter of the forming box 4. When the forming box 4 flips over to pour out the pressed tablets, the pressed tablets can fall into the collection box 2 through the notch at the bottom of the support base 3, thus collecting the pressed tablets. The operator can also pick up the collection box 2 as needed and catch the tablets while the forming box 4 is rotating, improving the flexibility of collection.

[0041] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric actuator 19, the drive unit 7, the water pump 8, and the heating unit are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0042] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
