Description
Technical Field
[0001] This utility model relates to the field of cosmetic production and processing equipment technology, and in particular to a powder compact extrusion device. Background Technology
[0002] With the rapid development of the cosmetics industry, consumers have increasingly higher requirements for product quality. In the production of pressed powder, since the initial state of pressed powder is powder, it is necessary to extrude the powdered raw materials into a solid form, so as to facilitate carrying and use. When extruding the powdered raw materials, a pressed powder extrusion device is required.
[0003] A search revealed Chinese patent publication number CN217597643U, which discloses a tableting device for powder coating production. The device includes a base, a support frame welded to the upper surface of the base, a first hydraulic cylinder mounted on the top of the support frame, a connecting plate fixed to the output end of the first hydraulic cylinder, a pressing block welded to the bottom of the connecting plate, a limit frame welded to the upper surface of the base, an extrusion mold clamped inside the limit frame, a partition plate welded to the inner side of the extrusion mold, a clamping shaft clamped inside the partition plate, a top plate welded to the top of the clamping shaft, a contact plate welded to the bottom of the clamping shaft, a second hydraulic cylinder mounted on the inner side of the top of the base, a support plate fixed to the output end of the second hydraulic cylinder, and a handle welded to the outer side of the extrusion mold. This device facilitates the removal of the extrusion mold for adding raw materials and the removal of the pressed powder after extrusion. However, in actual use, the hydraulic device, due to its complex structure, not only increases manufacturing and maintenance costs but also easily leads to environmental pollution and product quality degradation due to oil leakage. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a powder extrusion device, which aims to improve the problems of existing hydraulic devices, which are complex in structure, increasing manufacturing and maintenance costs, and are prone to environmental pollution and product quality degradation due to oil leakage.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a powder extrusion device, comprising a worktable, a support arm fixedly connected to the top of the worktable, threaded rods rotatably connected to the left and right sides of the top of the worktable, the top ends of the two threaded rods being rotatably connected to the support arm, two limiting rods fixedly connected to the left and right sides of the bottom of the outer wall of the support arm, the bottom ends of the two limiting rods being fixedly connected to the worktable, mounting plates slidably connected to the outer walls of the multiple limiting rods, the mounting plates being threadedly connected to the two threaded rods, ratchet wheels fixedly connected to the top of the outer walls of the two threaded rods, and a ratchet wheel provided on the outer side of the two ratchet wheels. The system includes a chain, with two ratchet wheels meshing with the chain. A motor is fixedly connected to the top left side of the support arm, and the output end of the motor passes through the support arm and is fixedly connected to the threaded rod on the left side. A lower mold is provided on the top of the worktable, and multiple screws are threaded to the left and right sides of the outer wall of the lower mold. The lower mold is threaded to the worktable through the screws. Multiple mold cavities are opened on the top of the lower mold. An upper mold is provided at the bottom of the mounting plate, and screws are threaded to all four sides of the outer wall of the upper mold. The upper mold is threaded to the mounting plate through the screws. A demolding mechanism is provided on the inner wall of the lower mold.
[0006] The above technical solution involves first installing the upper and lower molds in their respective areas, then starting the motor to rotate the left threaded rod. The rotation of the left threaded rod, via a chain, drives the right threaded rod to rotate synchronously. As the threaded rods rotate, the mounting plate moves vertically up and down along the limiting rod. The motor precisely controls the rotation of the threaded rods, thereby adjusting the height of the mounting plate to press powder cakes of different thicknesses. The upper mold moves with the mounting plate, and when the mounting plate descends, it moves the upper mold downwards closer to the lower mold. When the upper and lower molds close, the bottom of the upper mold and the top of the lower mold engage multiple cavities to extrude the powder cake material within the cavities.
[0007] As a further description of the above technical solution:
[0008] The demolding mechanism includes multiple ejector pins, which are slidably connected to the middle of the inner walls of multiple mold cavities. The inner wall of the lower mold has a reserved groove, and a sliding plate is slidably connected to the inner wall of the reserved groove. The bottom ends of the multiple ejector pins are fixedly connected to the sliding plate. The bottom of the sliding plate is fixedly connected to multiple springs, and the bottom ends of the multiple springs are fixedly connected to the reserved groove. The outer wall of the lower mold has sliding grooves on both the left and right sides. The inner walls of the two sliding grooves are slidably connected to connecting plates, and the two connecting plates are fixedly connected to the sliding plate. The bottom left and right sides of the upper mold are fixedly connected to pressing rods.
[0009] Through the above technical solution: as the upper mold moves downward, the pressing rod will first contact the connecting plate 206, and as the upper mold continues to descend, the pressing rod pushes the connecting plate to slide downward in the slide groove, thereby causing the sliding plate and the ejector pin to return to the bottom of the mold cavity. When the extrusion is completed, the upper mold moves upward, the pressing rod no longer applies pressure to the connecting plate, and the connecting plate slides upward under the action of the spring, driving the ejector pin to push the powder cake out of the mold cavity, thereby achieving automatic demolding.
[0010] As a further description of the above technical solution:
[0011] Multiple slide bars are fixedly connected to the left and right sides of the inner wall of the workbench, and storage plates are slidably connected to the outer walls of the multiple slide bars.
[0012] The above technical solution provides a temporary material storage area. Through its sliding connection with the slide bar, the storage plate can be smoothly pushed and pulled inside the workbench, saving space and keeping the work area clean.
[0013] As a further description of the above technical solution:
[0014] Dustproof plates are rotatably connected to the left and right sides of the outer wall of the workbench, and handles are fixedly connected to the front ends of the two dustproof plates.
[0015] The above technical solution prevents dust from entering the workbench and the materials on the storage plate, ensuring the quality of the powder cake raw materials and finished products. The handle provides operators with a convenient point of force to open and close the dustproof plate.
[0016] As a further description of the above technical solution:
[0017] The bottom of the workbench is fixedly connected to feet on all four sides, and each of the feet has a reserved hole in the middle of its outer wall.
[0018] The above technical solution provides a stable support base for the entire powder extrusion device, and the reserved holes are used to fix the device to the ground with bolts to prevent the device from shifting due to external forces during operation.
[0019] As a further description of the above technical solution:
[0020] A mounting box is fixedly connected to the top right side of the support arm, and an alarm light is fixedly connected to the inner wall of the mounting box.
[0021] The above technical solution enables an alarm light to illuminate when the device malfunctions, alerting operators to address the problem promptly.
[0022] As a further description of the above technical solution:
[0023] The lower mold has multiple positioning holes on its top front and rear sides, and the upper mold has multiple positioning rods fixedly connected to its bottom front and rear sides. The multiple positioning rods are slidably connected to the corresponding positioning holes.
[0024] With the above technical solution, when installing the mold, the operator can quickly find the installation position by using the sliding connection between the positioning rod and the positioning hole.
[0025] As a further description of the above technical solution:
[0026] A controller is fixedly connected to the right side of the outer wall of the support arm, and the controller is electrically connected to the motor and the alarm light.
[0027] Through the above technical solution, the controller can effectively manage the operating status of the entire device, thereby improving the operating efficiency of the device.
[0028] As a further description of the above technical solution:
[0029] This utility model has the following beneficial effects:
[0030] 1. In this utility model, the left threaded rod rotates and drives the right threaded rod to rotate synchronously via a chain. The motor can precisely control the rotation of the threaded rod, thereby adjusting the height of the mounting plate to press powder cakes of different thicknesses. This improves production efficiency and extends the service life of the equipment. Moreover, the manufacturing and maintenance costs are low, and there are no problems of environmental pollution and product quality decline caused by oil leakage.
[0031] 2. In this utility model, through the cooperation of the connecting plate and the spring, when the upper mold moves upward, the spring restores its deformation and pushes the sliding plate to move upward, so that the ejector pin can move upward after the extrusion is completed, thereby pushing the powder cake out of the mold cavity, realizing rapid demolding, reducing labor costs and operation time, making the device operation more convenient and efficient, and improving the practicality of the device.

[0040] 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.
[0041] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a powder extrusion device, including a worktable 1, which serves as the basic support platform for the entire device and provides installation positions for other components. A support arm 3 is fixedly connected to the top of the worktable 1, supporting and fixing other components and providing a stable structural frame for the operation of the device. Threaded rods 4 are rotatably connected to the left and right sides of the top of the worktable 1. Driven by a motor 9, these rods move up and down through threaded connections with a mounting plate 6, thereby driving the upper mold 13 to perform powder extrusion. The top ends of both threaded rods 4 are rotatably connected to the support arm 3. Two limiting rods 5 are fixedly connected to the left and right sides of the bottom of the outer wall of the support arm 3, and the bottom ends of both limiting rods 5 are fixedly connected to the worktable 1. Multiple limiting rods 5 have mounting plates slidably connected to their outer walls. The limiting rods 5 restrict the movement direction of the mounting plates 6, ensuring that the mounting plates 6 can only move in a straight line up and down, thus guaranteeing the accuracy and stability of the powder extrusion process. The mounting plates 6 are used to install and fix the upper mold 13. The mounting plates 6 are threadedly connected to two threaded rods 4. Ratchets 7 are fixedly connected to the top of the outer walls of the two threaded rods 4. Chains 8 are provided on the outer sides of the two ratchet wheels 7. The two ratchet wheels 7 are engaged with the chains 8, and the chains 8 are engaged with the two ratchet wheels 7. When the left threaded rod 4 rotates, the ratchet wheel 7 on the left threaded rod 4 drives the chain 8 to move, and the chain 8 drives the ratchet wheel 7 on the right threaded rod 4 to rotate, thereby achieving synchronous rotation of the two threaded rods 4. The top left side of the support arm 3 A motor 9 is fixedly connected, and the output end of the motor 9 passes through the support arm 3 and is fixedly connected to the left threaded rod 4. The motor 9 provides power to the device and drives the threaded rod 4 to rotate. A lower mold 10 is set on the top of the workbench 1. Multiple screws 11 are threaded to the left and right sides of the outer wall of the lower mold 10 to firmly fix the lower mold 10 on the workbench 1, ensuring the stability of the lower mold 10 during the extrusion of the powder cake. The lower mold 10 is threaded to the workbench 1 by screws 11. Multiple mold cavities 12 are opened on the top of the lower mold 10. The upper mold 13 is closed with the lower mold 10, and the mold cavity 12 forms a relatively closed space. The powder cake raw material is extruded and shaped in the mold cavity 12. The upper mold 13 is set at the bottom of the mounting plate 6, and the lower mold 10 is also located there. The upper mold 13 is formed by extruding the powder material. Screws 14 are threaded around the outer wall of the upper mold 13. The upper mold 13 is threaded to the mounting plate 6 through the screws 14. The screws 14 firmly fix the upper mold 13 to the mounting plate 6, ensuring the stability of the upper mold 13 during the powder extrusion process. The inner wall of the lower mold 10 is provided with a demolding mechanism 2. Multiple slide bars 15 are fixedly connected to the left and right sides of the inner wall of the worktable 1. Storage plates 16 are slidably connected to the outer walls of the multiple slide bars 15. The storage plates 16 provide a temporary material storage area. Through the sliding connection with the slide bars 15, the storage plates 16 can be smoothly pushed and pulled inside the worktable 1, saving space and keeping the work area clean.Dustproof plates 17 are rotatably connected to the left and right sides of the outer wall of the workbench 1. Handles 18 are fixedly connected to the front ends of the two dustproof plates 17. The dustproof plates 17 prevent dust from entering the interior of the workbench 1 and the materials on the storage plate 16, ensuring the quality of the powder cake raw materials and finished products. The handles 18 provide a convenient force point for the operator to open and close the dustproof plates 17, realizing the opening and closing operation of the dustproof plates 17.
[0042] Specifically, the starter motor 9 drives the left threaded rod 4 to rotate. After the left threaded rod 4 rotates, the ratchet 7 on the top of its outer wall engages with the chain 8, and the chain 8 engages with the ratchet 7 on the top of the right threaded rod 4. Therefore, the rotation of the left threaded rod 4 will drive the right threaded rod 4 to rotate synchronously through the chain 8. When the threaded rod 4 rotates, due to the action of the thread and the restriction of the limit rod 5, the mounting plate 6 can only move up and down linearly along the limit rod 5. The motor 9 adjusts the height of the mounting plate 6 by precisely controlling the position of the threaded rod 4, thereby achieving the pressing of powder cakes of different thicknesses. The upper mold 13 is threadedly connected to the mounting plate 6 by screw 14 and moves with the movement of the mounting plate 6. When the mounting plate 6 descends, it drives the upper mold 13 to rotate. The upper mold 13 moves downwards, gradually approaching the lower mold 10. When the upper mold 13 and the lower mold 10 are closed, the bottom of the upper mold 13 and the multiple mold cavities 12 at the top of the lower mold 10 cooperate to squeeze the powder cake raw material placed in the mold cavity 12. The storage plate 16 provides a temporary material storage area. The storage plate 16 can be smoothly pushed and pulled inside the workbench 1 through sliding connection with the slide bar 15, saving space and keeping the work area clean. The dustproof plate 17 prevents dust from entering the inside of the workbench 1 and the material on the storage plate 16, ensuring the quality of the powder cake raw material and the finished product. The handle 18 provides a convenient force point for the operator to open and close the dustproof plate 17, realizing the opening and closing operation of the dustproof plate 17.
[0043] Reference Figure 4 and Figure 5The demolding mechanism 2 includes multiple ejector pins 201, which eject the powder cake from the mold cavity 12 after the powder cake is formed, thus realizing the demolding operation. The multiple ejector pins 201 are slidably connected to the middle of the inner wall of the multiple mold cavities 12. The inner wall of the lower mold 10 is provided with a reserved groove 202 to provide space for the installation and sliding of the sliding plate 203. The sliding plate 203 is slidably connected to the inner wall of the reserved groove 202. The bottom ends of the multiple ejector pins 201 are all fixedly connected to the sliding plate 203. The sliding plate 203 connects to the ejector pins 201 and transmits motion to realize the up and down movement of the multiple ejector pins 201. The bottom of the sliding plate 203 is fixedly connected to multiple springs 204, and the bottom ends of the multiple springs 204 are all fixedly connected to the reserved groove 202. Next, after the demolding operation is completed, the spring 204 resets the sliding plate 203 and the ejector pin 201 to prepare for the next demolding operation. The lower mold 10 has sliding grooves 205 on both the left and right sides of its outer wall. The inner walls of the two sliding grooves 205 are slidably connected to the connecting plates 206. The sliding grooves 205 provide sliding tracks for the connecting plates 206 and limit the movement direction of the connecting plates 206. The connecting plates 206 are connected to the sliding plates 203 to transmit external force and realize the demolding operation. The two connecting plates 206 are fixedly connected to the sliding plates 203. The bottom left and right sides of the upper mold 13 are fixedly connected to the pressing rods 207. During the extrusion of the powder cake, the connecting plates 206 are pressed to make the ejector pin 201 return to the bottom of the mold cavity 12.
[0044] Specifically, when the upper mold 13 descends, the pressing rod 207 will first touch the connecting plate 206. As the upper mold 13 continues to descend, the pressing rod 207 will press the connecting plate 206 downward. After the connecting plate 206 is subjected to the pressure from above, it will drive the sliding plate 203 to move downward and compress the spring 204, thereby driving the sliding plate 203 to move downward. When the upper mold 13 moves downward to the mold closing position, the top of the ejector pin 201 is on the same horizontal line as the bottom of the mold cavity 12. After the pressing is finished, the upper mold 13 drives the pressing rod 207 to move upward. At the same time as the pressing rod 207 moves upward, the spring 204 gradually recovers its deformation, pushing the sliding plate 203 to move upward, thereby driving multiple ejector pins 201 to move upward and compress the powder cake in multiple mold cavities 12, thereby ejecting the powder cake from the inside of the mold cavity 12, thus achieving rapid demolding.
[0045] Reference Figure 1 , Figure 3 and Figure 6The bottom of the workbench 1 is fixedly connected to the four sides of the base with feet 19, which provide a stable support base for the entire powder extrusion device. The outer wall of each foot 19 is provided with a reserved hole 20, which is used to fix the device to the ground with bolts to prevent the device from shifting due to external forces during operation. The top right side of the support arm 3 is fixedly connected to the mounting box 21, which provides protection and installation position for the alarm light 22. The inner wall of the mounting box 21 is fixedly connected to the alarm light 22. When the device malfunctions, the alarm light 22 will light up to remind the operator to deal with the problem in time.

When the device malfunctions, the alarm light 22 will light up to remind the operator to deal with the problem in time.
[0047] Reference Figure 1 , Figure 4 and Figure 6 The lower mold 10 has multiple positioning holes 23 on its top front and rear sides, and the upper mold 13 has multiple positioning rods 24 fixedly connected to its bottom front and rear sides. The multiple positioning rods 24 are slidably connected to the corresponding positioning holes 23. When installing the upper mold 13, the operator can quickly find the installation position by using the sliding connection between the positioning rods 24 and the positioning holes 23, without repeated debugging and calibration, which greatly improves the convenience and efficiency of mold installation. The outer right side of the support arm 3 is fixedly connected to a controller 25. The controller 25 is electrically connected to the motor 9 and the alarm light 22. The controller 25 can effectively control the operating status of the entire device and improve the operating efficiency of the device.

[0049] Working principle: Before using the device, first install the upper mold 13 and the lower mold 10 in the corresponding areas. Start the motor 9 to drive the left threaded rod 4 to rotate. The rotation of the left threaded rod 4 drives the right threaded rod 4 to rotate synchronously through the chain 8. When the threaded rod 4 rotates, the mounting plate 6 moves up and down linearly along the limit rod 5. The motor 9 precisely controls the rotation of the threaded rod 4, thereby adjusting the height of the mounting plate 6 to press powder cakes of different thicknesses. The upper mold 13 moves with the mounting plate 6. When the mounting plate 6 descends, it drives the upper mold 13 to move downwards and closer to the lower mold 10. When the upper mold 13 and the lower mold 10 are closed, the bottom of the upper mold 13 is flush with the lower mold. Multiple mold cavities 12 at the top of mold 10 cooperate to extrude the powder material inside the mold cavity 12; and as the upper mold 13 moves downward, the pressing rod 207 will first contact the connecting plate 206, and as the upper mold 13 continues to descend, the pressing rod 207 pushes the connecting plate 206 to slide downward in the slide groove 205, thereby causing the sliding plate 203 and the ejector pin 201 to return to the bottom of the mold cavity 12. When the extrusion is completed, the upper mold 13 moves upward, the pressing rod 207 no longer applies pressure to the connecting plate 206, and the connecting plate 206 slides upward under the action of the spring 204, driving the ejector pin 201 to push the powder out of the mold cavity 12, thereby achieving automatic demolding.
