Description

Technical Field

[0001] The utility model relates to the technical field of powder coating processing equipment, in particular to a tablet pressing mechanism for powder coatings. Background Art

[0002] Thermosetting powder coatings are a new type of solvent-free 100% solid powder coating agent, which has the characteristics of pollution-free, recyclable, environmentally friendly, energy and resource saving, labor intensity reduction, and high film mechanical strength. Thermosetting powder coatings refer to coatings that use thermosetting resins as film-forming substances and add curing agents that undergo cross-linking reactions to form insoluble and infusible hard coatings after heating.

[0003] In the production and processing of powder coatings, the process of tablet pressing is required. Specifically, it is to use a tablet pressing mechanism to form the extruded and melted material into thin sheets. The basic working principle of the current pressing type tablet press is as follows: The raw materials are fed into a tank with a corresponding shape, and the pressing plate is driven by a driving cylinder to extrude and form the raw materials in the tank, and finally the raw materials in the tank are taken out. As can be seen from the above, although the traditional pressing type tablet pressing mechanism can extrude and form the raw materials into corresponding sheets, there are certain inconveniences in taking materials after pressing, which to a certain extent affects the efficiency of tablet pressing.

[0004] The purpose of the utility model is to provide a tablet pressing mechanism for powder coatings to solve at least one of the above technical problems.

[0005] To solve the above technical problems, the present application provides a tablet pressing mechanism for powder coatings, which includes a workbench and a material pressing component. A material pressing groove is provided on the workbench, a lower template is provided in the material pressing groove, and an upper template is provided above the lower template on the workbench;

[0006] The material pressing component includes a lifting driving member, a fixing plate and a fixing block.

[0007] An L-shaped connecting rod is provided on the outer extension of the upper template. A limiting groove is provided on one side of the material pressing groove on the workbench. One end of the L-shaped connecting rod is connected to the lower template, and the other end extends into the limiting groove. An elastic member is further provided in the limiting groove.

[0020] A first through groove is arranged on the lower side of the workbench, and the second connecting portion is adapted to be connected to the lower template through the second through groove;

[0021] In the above implementation process, the second limiting post can limit the first connecting portion of the first connecting rod to ensure the stability of the lifting movement of the first connecting rod.

[0033] Embodiment

[0034] During the production and processing of powder coatings, the tablet pressing process is required. Specifically, it uses a tablet pressing mechanism to form the extruded and melted material into thin sheets. Currently, the basic working principle of the press-type tablet press is as follows: The raw materials are fed into a tank with a corresponding shape, and the pressing plate is driven by a driving cylinder to extrude and form the raw materials in the tank. Finally, the raw materials in the tank are taken out. As can be seen from the above, although the traditional press-type tablet pressing mechanism can extrude and form the raw materials into corresponding sheets, there are certain inconveniences in taking the materials after pressing, which affects the efficiency of tablet pressing to a certain extent. To solve the above technical problems, the following technical solutions are provided in this embodiment:

[0035] Specifically, please refer to Figure 1-2 , this embodiment provides a powder coating tablet pressing mechanism, including a workbench 10 and a material pressing assembly. A material pressing groove 11 is provided on the workbench 10, a lower template 21 is provided in the material pressing groove 11, and an upper template 22 is provided above the lower template 21 on the workbench 10;

[0036] Specifically, the material pressing assembly includes a lifting driving member 31, a fixing plate 32 and a fixing block. The lifting driving member 31 is provided on the workbench 10, the fixing plate 32 is provided at the driving end of the lifting driving member 31, and the fixing block 33 is provided on the side of the fixing plate 32 close to the upper template 22. The lifting driving member 31 is adapted to drive the fixing plate 32 to move in the vertical direction to drive the fixing block to abut against the upper template 22 and press down;

[0037] Specifically, an L-shaped connecting rod 221 is provided on the outer extension of the upper template 22. A limiting groove 222 is provided on one side of the material pressing groove 11 on the workbench 10. One end of the L-shaped connecting rod 221 is connected to the lower template 21, and the other end extends into the limiting groove 222. An elastic member 223 is also provided in the limiting groove 222. One end of the elastic member 223 abuts against the inner wall of the limiting groove 222, and the other end abuts against the end of the L-shaped connecting rod 221;

[0038] Furthermore, it further includes a first connecting rod 40. One end of the first connecting rod 40 is located above the fixing plate 32, and the other end is fixedly connected to the lower template 21. The fixing plate 32 is adapted to lift the first connecting rod 40;

[0039] In the above solution, the staff activates the lifting drive member 31, and the lifting drive member 31 drives the fixed plate 32 and the fixed block to press down. During the downward movement of the fixed plate 32, the first connecting rod 40 supported by it also moves downward under the action of gravity. The first connecting rod 40 is connected to the lower template 21. At this time, the lower template 21 also moves downward until it touches the bottom end of the material pressing groove 11 and will not move further downward. The staff can introduce the material into the material pressing groove 11. Subsequently, the lifting drive member 31 further drives the fixed plate 32 to press down, and the fixed block acts on the upper template 22 to drive the upper template 22 to press down, and cooperate with the lower template 21 to press the material in the material pressing groove 11 into a sheet; after the material is formed, the lifting drive member 31 rises to drive the fixed plate 32 to rise and lift the first connecting rod 40 again. The first connecting rod 40 rises to drive the lower template 21 to rise and send the formed material out of the material pressing groove 11, which can realize the rapid demolding of the material, facilitate the subsequent rapid transfer of the sheet material, and improve the work efficiency; when the upper template 22 is under the pressing action of the fixed block, it stores elastic potential energy through the elastic member 223, and then releases the elastic potential energy to push up the upper template 22 after losing the pressing action of the fixed block. In this way, it is not necessary to use the lifting drive member 31 to drive the reset of the upper template 22, but the automatic reset is realized through the elastic member 223.

[0040] It should be noted that in one of the embodiments, the upper template 22 can also be directly fixedly connected to the fixed block 33. At this time, there is no need to provide the elastic member 223, the L-shaped connecting rod 221 and the limiting groove 222; at this time, the lifting drive member 31 drives the lifting of the upper template 22; it can be understood that both of the above two methods provided in this embodiment are acceptable. The method of directly fixedly connecting the upper template 22 can reduce the setting of the mechanism, but at the same time increase the jacking load capacity of the lifting drive member 31. Therefore, the corresponding setting method can be selected according to the actual application situation.

[0041] Specifically, the lifting drive member 31 includes electric telescopic rods. There are four electric telescopic rods, and the four electric telescopic rods are respectively arranged at the four corners of the fixed plate 32;

[0042] In the above solution, the electric telescopic rod is more conducive to the two-stage operation during the material pressing process and realizes more flexible control. And setting the electric telescopic rods to four and respectively located at the four corners of the fixed plate 32 can improve the load capacity of the lifting drive member 31 and ensure uniform stress at the same time.

[0043] It can be understood that in some of the embodiments, the lifting drive member 31 can also adopt other drive mechanisms, such as a driving cylinder, etc.

[0044] Specifically, a refrigeration mechanism 50 is provided in the middle of the lower part of the workbench 10, and the refrigeration mechanism 50 is used to cool the material in the material pressing groove 11;

[0045] In the above solution, the refrigeration mechanism 50 can lower the temperature of the workbench 10, improve the cooling speed of the sheet material, and thus improve the tableting efficiency of the material.

[0046] It should be noted that the refrigeration mechanism 50 belongs to a relatively mature technology in the prior art, and it is also relatively common to adopt the refrigeration mechanism 50 in the tableting mechanism. Therefore, this application will not elaborate further on this.

[0047] Specifically, a feed pipe 70 is provided on the side wall of the workbench 10, and the feed pipe 70 is communicated with the pressing groove 11.

[0048] In the above solution, the feed pipe 70 can realize the automatic introduction of the material, effectively reduce the workload of the staff, and at the same time improve the introduction efficiency of the material and the accuracy of the quantity of the introduced material.

[0049] It can be understood that the feed pipe 70 can be connected to the upstream mechanism, and in some other embodiments, a flow monitoring mechanism can also be set up to monitor the approximate quantity of the introduced material.

[0050] Specifically, a first limiting post 224 is provided in the limiting groove 222, and a sliding groove adapted to the first limiting post 224 is formed at one end of the L-shaped connecting rod 221 extending into the limiting groove 222; the elastic member 223 includes a compression spring, and the compression spring is wound around the outer periphery of the limiting post.

[0051] In the above solution, the cooperation between the first limiting post 224 and the sliding groove can limit the lifting action of the upper template 22, thereby making its lifting process more stable and achieving better pressing of the material.

[0052] Specifically, the first connecting rod 40 includes a first connecting portion 41 in a C shape and a second connecting portion 42 in a rod shape; one end of the first connecting portion 41 is located above the fixed plate 32, the other end is connected to one end of the second connecting portion 42, and the other end of the second connecting portion is connected to the lower part of the lower template 21.

[0053] Furthermore, a second limiting post 43 is provided on the fixed plate 32, and the second limiting post 43 is adapted to pass through the first connecting portion 41 located above the fixed plate 32 to limit the first connecting rod 40.

[0054] Specifically, a first through groove is provided on the lower side of the workbench 10, and the second connecting portion 42 is adapted to be connected to the lower template 21 through a second through groove.

[0055] In the above solution, the second limiting post 43 can limit the first connecting portion 41 of the first connecting rod 40 to ensure the stability of the lifting action of the first connecting rod 40.

[0056] Specifically, a support plate 61 is provided below the workbench 10, and a support column 62 is provided on the support plate 61. The other end of the support column 62 is connected to the bottom surface of the workbench 10;
