Description

Technical Field

[0001] This utility model belongs to the field of powder tableting technology, and specifically relates to a tableting device for thermosetting powder coatings. Background Technology

[0002] Thermosetting powder coating tableting equipment plays a crucial role in the powder coating processing field. It places powdered coatings into a special mold and uses pressure to shape them into sheet-like materials. This tableting process effectively improves the convenience of storing and transporting powder coatings.

[0003] However, the current tableting device makes it difficult to remove the sheet material after molding. Because the sheet material of thermosetting powder coating is tightly attached to the mold after molding, there is a lack of convenient and effective means of removing the sheet, which often requires the use of tools to pry it off. This not only consumes a lot of manpower and reduces production efficiency, but also easily damages the sheet material, such as causing scratches and edge damage, which seriously affects the appearance quality of the product and greatly reduces the yield of the finished product.

[0004] In view of this, this application proposes a tableting device for thermosetting powder coatings to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a tableting device for thermosetting powder coatings. By designing an ejection component, the device facilitates the ejection of the formed sheet material from the mold cylinder after the powder coating tableting process is completed, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A tableting device for thermosetting powder coatings includes a fixed frame, wherein an ejection assembly is provided within the fixed frame;

[0008] The ejection assembly includes a mold cylinder disposed above the fixed frame, a pressing block disposed above the mold cylinder, a circular groove opened in the lower part of the mold cylinder, an ejection block disposed in the circular groove, a lifting rod fixedly connected below the ejection block, a support plate installed below the lifting rod, and an inner support plate disposed below the support plate.

[0009] A threaded cylinder is movably installed below the inner support plate. A lifting screw is threadedly connected inside the threaded cylinder. The upper end of the lifting screw is fixedly connected to the support plate. A driven gear ring is installed on the outer side below the threaded cylinder. A drive gear is meshed with one side of the driven gear ring. A drive motor is located below the drive gear.

[0010] With the above technical solution, when tableting is being performed, the pressure acting on the ejector block is transmitted to the support plate via the lifting rod. At this time, the inner support plate, relying on the support plate, steadily bears the downward pressure, effectively preventing the pressure from being further transmitted to the lifting screw, thus avoiding the potential risk of damage to the threaded connection due to pressure impact.

[0011] In a preferred embodiment, the output shaft of the drive motor is fixedly connected to the drive gear, the lower end of the drive motor is fixedly connected to the fixed frame, a set of side support rods are fixedly connected to both sides of the support plate, a guide rod is fixedly connected below the side support rods, the lower end of the guide rod passes through the inner support plate, and the inner support plate is fixedly connected to the inner wall of the fixed frame.

[0012] With the above technical solution, when the drive motor starts, it can drive the driving gear to rotate. The meshing transmission between the driving gear and the driven gear ring then drives the threaded cylinder to rotate outside the lifting screw. This action causes the lifting screw to drive the support plate to rise, and the support plate, in turn, is linked to the ejector block through the lifting rod, causing it to rise and completely eject the sheet material inside the mold cylinder.

[0013] In a preferred embodiment, the upper surface of the fixing frame is provided with a cylindrical groove, the lower end of the mold cylinder is located in the cylindrical groove, a limiting ring is provided on the upper outer side of the mold cylinder, and a fixing rod is fixedly connected to each side of the limiting ring. The lower end of the fixing rod is fixedly connected to the fixing frame through a side upright.

[0014] Through the above technical solution, the limiting ring can limit the position of the mold cylinder, preventing the mold cylinder from shaking during the tableting process and affecting the tableting effect.

[0015] In a preferred embodiment, a workbench is fixedly connected below the fixed frame, a hydraulic cylinder is provided above the tablet pressing block, a vertical plate is installed behind the upper surface of the workbench, the upper end of the hydraulic cylinder is fixedly connected to the vertical plate, and the hydraulic cylinder is fixedly connected to the tablet pressing block through a piston rod.

[0016] The above technical solution uses a hydraulic cylinder to drive a piston rod, which in turn lowers the tablet block into the mold cylinder. As the hydraulic cylinder continues to apply pressure, the tablet block exerts pressure on the powder material inside the mold cylinder, causing the powder to compact and form into a sheet-like material.

[0017] In a preferred embodiment, a side platform is installed on one side of the upper surface of the workbench, and multiple sets of placement slots are equidistantly formed on the upper surface of the side platform, with a storage cylinder placed in each set of placement slots.

[0018] With the above technical solution, after the powder coating is pressed into tablets, the formed tablet material can be stored in a tablet storage cylinder for easy classification management and subsequent quick retrieval.

[0019] In a preferred embodiment, a transfer assembly is provided above the storage cylinder. The transfer assembly includes a vacuum suction cup located above the storage cylinder, an electric push rod installed above the vacuum suction cup, and a vacuum generator located on one side of the electric push rod. The vacuum generator is fixedly connected to the vacuum suction cup via a connecting hose.

[0020] Through the above technical solution, the vacuum generator can perform vacuuming on the vacuum suction cup, so that the vacuum suction cup can adsorb sheet material.

[0021] In a preferred embodiment, a horizontal frame is provided above the electric actuator, a rotating lead screw is installed inside the horizontal frame, a horizontal sliding block is connected to the middle of the rotating lead screw by a thread, a partition is installed on one side inside the horizontal frame, a servo motor is fixedly installed on one side of the partition, the output shaft of the servo motor is fixedly connected to the rotating lead screw, and the upper end of the electric actuator is slidably connected to the horizontal sliding block.

[0022] Through the above technical solution, the servo motor can drive the rotating lead screw to rotate, and through the transmission of the threaded connection, it can cause the horizontal slider to slide flexibly within the horizontal frame, thereby driving the vacuum suction cup to achieve precise horizontal movement.

[0023] In a preferred embodiment, a circular plate is fixedly connected to one side of the horizontal frame, the vacuum generator is fixedly installed below the circular plate, a transfer motor is provided above the circular plate, a fixing plate is fixedly connected above the transfer motor, the lower end of the fixing plate is fixedly connected to the worktable, the output shaft of the transfer motor is fixedly connected to the circular plate, and a limiting rod is fixedly installed on the left and right sides of the rear upper surface of the worktable.

[0024] Through the above technical solution, the transfer motor can drive the horizontal frame to rotate through the circular plate, so that the vacuum suction cup moves to the position directly above the mold cylinder. During the rotation, the limiting rod can limit the horizontal frame to prevent the horizontal frame from shifting position when rotating.

[0025] After adopting the above technical solution, the beneficial effects of this utility model are:

[0026] 1. By designing the ejector assembly, the axial driving force generated when the threaded cylinder rotates outside the ejector screw causes the ejector block to rise inside the mold cylinder, conveniently ejecting the sheet material that has been pressed into shape inside the mold cylinder, ensuring the appearance integrity and structural stability of the sheet material. Compared with the traditional method of using tools to pry out sheet material, this effectively avoids the risk of breakage during prying, ensuring product quality. Furthermore, the pressure borne by the ejector block is transmitted to the support plate via the lifting rod, at which point the inner support plate, relying on the support plate, steadily bears the downward pressure.

[0027] 2. By designing a transfer assembly, after the sheet material is successfully ejected by the ejection assembly, the vacuum suction cup can hold the formed sheet material. It is then sequentially transferred to multiple storage cylinders pre-positioned on the side platform for storage. Compared to manual transfer, the vacuum suction cup avoids direct contact between human hands and the sheet material, minimizing the risk of contamination and scratches caused by human factors. This effectively ensures the cleanliness and integrity of the sheet material surface. Furthermore, the orderly storage of the sheet material in multiple storage cylinders facilitates classification management and rapid subsequent retrieval, and the entire transfer process is highly efficient and smooth.

Detailed Implementation

[0035] 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.

[0036] Please see Figures 1 to 5 A tableting device for thermosetting powder coatings includes a fixed frame 2, and an ejector assembly 9 is provided inside the fixed frame 2;

[0037] The ejection assembly 9 includes a mold cylinder 97 located above the fixed frame 2. A pressing block 5 is located above the mold cylinder 97. A circular groove is opened in the lower part of the mold cylinder 97. An ejection block 915 is located in the circular groove. A lifting rod 96 is fixedly connected below the ejection block 915. A support plate 99 is installed below the lifting rod 96. An inner support plate 914 is located below the support plate 99.

[0038] A threaded cylinder 94 is movably installed below the inner support plate 914. A lifting screw 91 is threadedly connected inside the threaded cylinder 94. The upper end of the lifting screw 91 is fixedly connected to the support plate 99. A driven gear ring 95 is installed on the outer side below the threaded cylinder 94. A drive gear 93 is meshed on one side of the driven gear ring 95. A drive motor 92 is located below the drive gear 93.

[0039] During tableting, the pressure acting on the ejector block 915 is transmitted to the support plate 99 via the lifting rod 96. At this time, the inner support plate 914, relying on the support plate 99, steadily bears the downward pressure, effectively preventing the pressure from being further transmitted to the lifting screw 91, thus avoiding the potential risk of damage to the threaded connection due to pressure impact.

[0040] The output shaft of the drive motor 92 is fixedly connected to the drive gear 93. The lower end of the drive motor 92 is fixedly connected to the fixed frame 2. A set of side support rods 910 are fixedly connected to both sides of the support plate 99. A guide rod 98 is fixedly connected below the side support rods 910. The lower end of the guide rod 98 passes through the inner support plate 914. The inner support plate 914 is fixedly connected to the inner wall of the fixed frame 2.

[0041] When the drive motor 92 starts, it drives the drive gear 93 to rotate. The meshing transmission between the drive gear 93 and the driven gear ring 95 then drives the threaded cylinder 94 to rotate outside the lifting screw 91. This action causes the lifting screw 91 to drive the support plate 99 to rise, and the support plate 99, in turn, lifts the ejector block 915 through the lifting rod 96, thus ejecting the sheet material completely from the mold cylinder 97.

[0042] The upper surface of the fixed frame 2 is provided with a cylindrical groove, the lower end of the mold cylinder 97 is located in the cylindrical groove, and a limiting ring 911 is provided on the outer side of the upper part of the mold cylinder 97. A fixing rod 913 is fixedly connected to each side of the limiting ring 911, and the lower end of the fixing rod 913 is fixedly connected to the fixed frame 2 through the side upright 912.

[0043] The limiting ring 911 can limit the position of the mold cylinder 97 to prevent the mold cylinder 97 from shaking during the tableting process and affecting the tableting effect.

[0044] A workbench 1 is fixedly connected below the fixed frame 2. A hydraulic cylinder 4 is provided above the tablet pressing block 5. A vertical plate 3 is installed behind the upper surface of the workbench 1. The upper end of the hydraulic cylinder 4 is fixedly connected to the vertical plate 3. The hydraulic cylinder 4 is fixedly connected to the tablet pressing block 5 through the piston rod.

[0045] The hydraulic cylinder 4 drives the piston rod to lower the tablet block 5 into the mold cylinder 97. As the hydraulic cylinder 4 continues to apply pressure, the tablet block 5 applies pressure to the powder material in the mold cylinder 97, causing the powder to be compacted and formed into a sheet material.

[0046] A side table 6 is installed on one side of the upper surface of the workbench 1. Multiple sets of placement slots are equally spaced on the upper surface of the side table 6, and a storage cylinder 7 is placed in each set of placement slots.

[0047] After the powder coating is pressed into tablets, the formed tablets can be stored in the tablet storage cylinder 7 for easy classification and management and quick retrieval.

[0048] A transfer assembly 8 is provided above the film storage cylinder 7. The transfer assembly 8 includes a vacuum suction cup 87 located above the film storage cylinder 7. An electric push rod 86 is installed above the vacuum suction cup 87. A vacuum generator 88 is provided on one side of the electric push rod 86. The vacuum generator 88 is fixedly connected to the vacuum suction cup 87 through a connecting hose.

[0049] The vacuum generator 88 can perform vacuuming on the vacuum suction cup 87, so that the vacuum suction cup 87 can adsorb the sheet material.

[0050] A horizontal frame 81 is provided above the electric actuator 86. A rotating lead screw 84 is installed inside the horizontal frame 81. A horizontal sliding block 85 is connected to the middle of the rotating lead screw 84 by a thread. A partition 82 is installed on one side inside the horizontal frame 81. A servo motor 83 is fixedly installed on one side of the partition 82. The output shaft of the servo motor 83 is fixedly connected to the rotating lead screw 84. The upper end of the electric actuator 86 is slidably connected to the horizontal sliding block 85.

[0051] The servo motor 83 can drive the rotating lead screw 84 to rotate, and through the transmission of the threaded connection, it causes the horizontal slider 85 to slide flexibly within the horizontal frame 81, thereby driving the vacuum suction cup 87 to achieve precise horizontal movement.

[0052] A circular plate 811 is fixedly connected to one side of the horizontal frame 81. A vacuum generator 88 is fixedly installed below the circular plate 811. A transfer motor 89 is provided above the circular plate 811. A fixing plate 810 is fixedly connected above the transfer motor 89. The lower end of the fixing plate 810 is fixedly connected to the worktable 1. The output shaft of the transfer motor 89 is fixedly connected to the circular plate 811. A limit rod is fixedly installed on the left and right sides of the rear of the upper surface of the worktable 1.

[0053] The transfer motor 89 can drive the horizontal frame 81 to rotate 180° through the circular plate 811, so that the vacuum suction cup 87 moves to the position directly above the mold cylinder 97. During the rotation, the limiting rod can limit the horizontal frame 81 to prevent the horizontal frame 81 from shifting position when rotating.

[0054] In practical use, the working principle of this utility model is as follows:

[0055] In use, thermosetting powder coating is added into mold cylinder 97, and hydraulic cylinder 4 drives piston rod to lower pressing block 5 into mold cylinder 97. As hydraulic cylinder 4 continuously applies pressure, pressing block 5 applies pressure to the powder material in mold cylinder 97, causing the powder to compact and form into sheet material. During the pressing process, the pressure acting on ejector block 915 is transmitted to support plate 99 via lifting rod 96. At this time, inner support plate 914, relying on support plate 99, steadily bears the downward pressure, effectively preventing the pressure from being further transmitted to lifting screw 91, avoiding the risk of damage to threaded connection due to pressure impact. After pressing is completed, hydraulic cylinder 4 drives pressing block 5 to rise, disengaging it from inside mold cylinder 97, making way for the subsequent transfer of sheet material. Subsequently, drive motor 92 starts, driving drive gear 93 to rotate. The meshing transmission between drive gear 93 and driven gear ring 95 then drives threaded cylinder 94 to rotate outside lifting screw 91. This action causes the lifting screw 91 to raise the support plate 99, which in turn, through the lifting rod 96, lifts the ejector block 915, thus ejecting the sheet material completely from the mold cylinder 97. As the support plate 99 rises, it is guided by the side support rod 910 to the guide rod 98, which rises smoothly along a predetermined straight path, providing guidance for its movement and ensuring stable, unbiased ascent. Then, the transfer motor 89 is activated, which, through the circular plate 811, rotates the horizontal frame 81 180°, moving the vacuum suction cup 87 to a position directly above the mold cylinder 97. As the sheet material is ejected, the electric actuator 86 pushes the vacuum suction cup 87 downwards, allowing it to enter the mold cylinder 97 and contact the sheet material. The vacuum generator 88 evacuates the vacuum suction cup 87, causing it to adhere to the sheet material. Then, the electric actuator 86 is activated again, lifting the vacuum suction cup 87, which is adsorbing the sheet material, out of the mold cylinder 97. Next, following the aforementioned transmission path, the horizontal frame 81 is rotated 180° and moved above the storage cylinder 7. Subsequently, the electric push rod 86 drives the adsorbed sheet material to descend, causing it to fall into the storage cylinder 7. Finally, the adsorption state of the vacuum suction cup 87 is released, thus completing the sheet material storage process.

[0056] Before the sheet material is inserted, the servo motor 83 drives the rotating lead screw 84 to rotate. Through the threaded transmission, the transverse slider 85 slides flexibly within the horizontal frame 81, thereby driving the vacuum suction cup 87 to achieve precise lateral movement. If any storage cylinder 7 is full during production, the position of the vacuum suction cup 87 and the electric push rod 86 can be adjusted using the lateral adjustment function to ensure that the sheet material can be inserted into an empty storage cylinder, maintaining production continuity. When it is necessary to remove material from the mold cylinder 97, the vacuum suction cup 87 is adjusted laterally to a position above the mold cylinder 97 to initiate the removal process.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
