Description

Technical Field

[0001] This utility model relates to a powder pressing device, and more particularly to an automated powder pressing machine. Background Technology

[0002] Pressed powder, primarily used for touch-ups, is a cosmetic product made by pressing a mixture of powder and base. Its shape varies depending on the container. The production process of pressed powder includes: raw material preparation and proportioning, mixing and grinding, binder preparation and addition, pressing and molding, and settling and inspection. Pressing involves using pressure equipment and molds to press the powder into a fixed shape; large molds can produce a large quantity of pressed powder at once. Existing pressed powder equipment is highly efficient, but the equipment itself is costly. Furthermore, due to the high cost of mold making, it is not suitable for small-scale production or experimentation. Therefore, there is a need to develop a low-cost, automated powder pressing device suitable for small-scale production or experimentation. Summary of the Invention

[0003] This invention provides an automated powder pressing machine, which solves the problem that existing powder pressing equipment is not suitable for small-scale production or experimentation.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: An automated powder pressing machine includes a base and two side plates disposed on the base. A top cover is fixedly connected to the top of the two side plates. A sliding seat is horizontally slidably mounted on the base, with the sliding direction being the front-to-back direction of the base. A lead screw nut is provided on the sliding seat. A lead screw cooperating with the lead screw nut is horizontally rotatably connected to the base. A servo motor for driving the lead screw to rotate is also provided. A horizontal platform is provided on the upper side of the sliding seat. A fixed clamping block and a cylinder are fixed on the horizontal platform. A movable clamping block is fixed on the telescopic rod of the cylinder. A horizontal baffle is fixed opposite to the fixed clamping block on its upper side. A feeding plate is provided on the horizontal baffle. The filling hole has a diameter that matches the inner diameter of the powder bottle. A movable clamping block can clamp the powder bottle located between itself and the fixed clamping block, aligning it with the filling hole. The upper opening of the powder bottle abuts against the bottom surface of the horizontal baffle. The top cover is vertically equipped with a filling tube and a servo cylinder. The upper end of the filling tube can be connected to a powder hopper or powder supply device. The bottom of the filling tube is in contact with the upper surface of the horizontal baffle, and the inner diameter of the filling tube is greater than or equal to the filling hole. The telescopic rod of the servo cylinder is vertically downward, and a powder pressing block adapted to the shape of the filling hole is fixed on the telescopic rod. The sliding seat can be driven by the lead screw to move the filling hole on it sequentially until it is aligned with the filling tube and the powder pressing block.

[0005] The operating steps of this utility model are as follows: For feeding, the utility model controls the servo motor to rotate according to a preset control program, driving the sliding seat to move to the foremost position. At this time, the horizontal platform and its accessories are exposed from the clamping area of ​​the two side plates. Simultaneously, the cylinder is in a retracted state, and the distance between the movable and fixed clamping blocks is at its maximum. The servo cylinder is also in a retracted state, and the rear end of the horizontal baffle is in contact with the bottom of the filling pipe, achieving a sealing effect. Then, the operator manually places the powder bottle into the area between the movable and fixed clamping blocks. For filling, the equipment controls the cylinder to extend according to a preset control program. At this time, the movable clamping block pushes the powder bottle, causing it to abut against the fixed clamping block. At this time, the filling hole is vertically aligned with the powder bottle. The clamping parts of the two clamping blocks generally have slots adapted to the outer contour of the powder bottle for precise positioning. Then, the servo motor rotates, driving... The sliding seat moves to below the filling tube and stops, so that the filling hole on the horizontal baffle is aligned with the filling tube. The upper end of the filling tube can be connected to the powder hopper or powder supply device. The powder in the filling tube will automatically fall into the powder bottle and fill the powder bottle and filling hole. Pressing: The equipment controls the servo motor to rotate according to the preset control program, driving the sliding seat to move to below the pressing block and stop. At this time, the front end of the horizontal baffle is in contact with the bottom of the filling tube, which has a sealing effect. The filling hole and the pressing block are aligned vertically. Then the servo cylinder is extended under control, and its extension length is a preset fixed value to ensure that the pressing block compresses the powder to be flush with or slightly lower than the bottle opening. Then the servo cylinder resets. Discharging: The equipment controls the servo motor to rotate according to the preset control program, driving the sliding seat to move to the front end. The cylinder retracts, and the operator removes the powder bottle filled with powder.

[0006] Furthermore, the sliding seat includes a base plate, two support plates, and a horizontal platform. The lead screw nut has horizontal surfaces on both sides, which are in contact with the inner walls of the two support plates. The support plates have two limiting blocks that clamp the front and rear ends of the lead screw nut. Through this technical solution, only a horizontal thrust is generated between the lead screw nut and the sliding seat. The sliding seat cannot exert downward pressure on the lead screw nut, therefore the lead screw will not be subjected to downward pressure. This ensures that the lead screw remains straight, as it cannot undergo significant deformation.

[0007] Furthermore, the upper surface of the horizontal baffle is provided with two powder-blocking ribs parallel to the moving direction of the sliding seat, and powder-blocking plates are provided at the front and rear ends of the horizontal baffle. The powder-blocking ribs and powder-blocking plates can define a receiving cavity on the upper surface of the horizontal baffle. As the sliding seat moves, the filling pipe will reciprocate within the receiving cavity area. As the working time increases, powder will inevitably leak out from the gaps. This receiving cavity can restrain this powder and prevent it from falling onto the lead screw and load-bearing slide rail, so as to avoid contamination of these components and reduced mobility.

[0008] Therefore, this utility model has the following characteristics compared with the prior art: 1. This utility model can automatically press powder into the powder bottle, eliminating the need for special molds, making it simple to operate, with a simplified structure and relatively low cost, making it suitable for small-scale production or experimentation.

[0018] Example 1: See Figure 1 and Figure 2An automated powder compact press includes a base 10 and two side plates 11 mounted on the base. A top cover 12 is fixedly connected to the top of each side plate. A sliding seat 20 is horizontally slidable on the base in the front-to-back direction. A lead screw nut 31 is mounted on the sliding seat. A lead screw 30, cooperating with the lead screw nut, is horizontally rotatably connected to the base. A servo motor 32 drives the lead screw to rotate. A horizontal platform 21 is mounted on the upper side of the sliding seat. A fixed clamping block 22 and a cylinder 23 are fixed on the horizontal platform. A movable clamping block 24 is fixed on the telescopic rod of the cylinder. A horizontal baffle 25 is fixed opposite to the fixed clamping block on its upper side. A filling hole 26 is provided on the horizontal baffle. The thickness of the horizontal baffle is 1 / 3 of the inner depth of the powder compact bottle 100. The diameter of the filling hole is the same as the inner diameter of the powder bottle. The movable clamp can clamp the powder bottle located between itself and the fixed clamp and make it face the filling hole. The upper opening of the powder bottle just abuts the bottom surface of the horizontal baffle. The top cover is vertically equipped with a filling tube 40 and a servo cylinder 50. The upper end of the filling tube can be connected to the powder hopper or powder supply device. The bottom of the filling tube is in contact with the upper surface of the horizontal baffle, and the inner diameter of the filling tube is greater than or equal to the filling hole. The telescopic rod of the servo cylinder is set vertically downward. A powder pressing block 51 that matches the shape of the filling hole is fixed on the telescopic rod. The lower edge of the powder pressing block is rounded or chamfered. The sliding seat can be driven by the screw to move the filling hole on it in sequence to face the filling tube and the powder pressing block.

[0019] See Figures 3 to 6The operation steps of this embodiment are as follows: Feeding: In this embodiment, the servo motor is controlled to rotate according to a preset control program, driving the sliding seat to move to the foremost position. At this time, the horizontal platform and its accessories are exposed from the clamping area of ​​the two side plates. Simultaneously, the cylinder is in a retracted state, and the distance between the movable clamping block and the fixed clamping block is at its maximum value. The servo cylinder is also in a retracted state, and the rear end of the horizontal baffle is in contact with the bottom of the filling pipe, achieving a sealing effect. Then, the operator manually places the powder bottle into the area between the movable and fixed clamping blocks. Powder Filling: The equipment controls the cylinder to extend according to a preset control program. At this time, the movable clamping block pushes the powder bottle, causing it to abut against the fixed clamping block. At this time, the filling hole is vertically aligned with the powder bottle. The clamping parts of the two clamping blocks generally have slots adapted to the outer contour of the powder bottle for precise positioning. Then, the servo motor rotates, driving... The sliding seat moves to below the filling tube and stops, so that the filling hole on the horizontal baffle is aligned with the filling tube. The upper end of the filling tube can be connected to the powder hopper or powder supply device. The powder in the filling tube will automatically fall into the powder bottle and fill the powder bottle and filling hole. Pressing: The equipment controls the servo motor to rotate according to the preset control program, driving the sliding seat to move to below the pressing block and stop. At this time, the front end of the horizontal baffle is in contact with the bottom of the filling tube, which has a sealing effect. The filling hole and the pressing block are aligned vertically. Then the servo cylinder is extended under control, and its extension length is a preset fixed value to ensure that the pressing block compresses the powder to be flush with or slightly lower than the bottle opening. Then the servo cylinder resets. Discharging: The equipment controls the servo motor to rotate according to the preset control program, driving the sliding seat to move to the front end. The cylinder retracts, and the operator removes the powder bottle filled with powder.

[0020] See Figure 2 The base is equipped with two load-bearing slide rails 13, and the bottom of the sliding seat is equipped with four sliders 14 that slide in conjunction with the two load-bearing slide rails. The load-bearing slide rails are used to support the weight of the sliding seat and the pressure from the servo electric cylinder, and also serve as sliding guides.

[0021] See Figure 2 and Figure 7 The sliding seat includes a base plate 27, two support plates 28, and a horizontal platform. Horizontal surfaces 311 are provided on both sides of the lead screw nut, and these two horizontal surfaces are in contact with the inner walls of the two support plates. Two limiting blocks 281 are provided on the support plates, clamping the front and rear ends of the lead screw nut. Through this technical solution, only a horizontal thrust is generated between the lead screw nut and the sliding seat. The sliding seat cannot exert downward pressure on the lead screw nut, therefore the lead screw will not be subjected to downward pressure. This ensures that the lead screw remains straight, as the lead screw cannot undergo significant deformation.

[0022] See Figure 2The filling pipe consists of a rigid metal pipe 41 and a rubber sleeve 42 connected to the lower end of the rigid metal pipe. The rubber sleeve is fitted to the upper surface of the horizontal baffle. The rubber sleeve has good elasticity and wear resistance, so the seal between the rubber sleeve and the horizontal baffle is good, which can effectively reduce the probability of powder leakage from the filling pipe.

[0023] See Figure 1 The upper surface of the horizontal baffle is provided with two powder-blocking ribs 251 parallel to the moving direction of the sliding seat, and powder-blocking plates 252 are provided at the front and rear ends of the horizontal baffle. The powder-blocking ribs and powder-blocking plates can define a receiving cavity on the upper surface of the horizontal baffle. As the sliding seat moves, the filling pipe will reciprocate within the receiving cavity area. As the working time increases, powder will inevitably leak out from the gaps. This receiving cavity can restrain this powder and prevent it from falling onto the lead screw and load-bearing slide rail, so as to avoid contamination of these components and reduced mobility.

[0024] See Figure 1 and Figure 2 The upper front end of the lead screw is covered with a powder-blocking tile 33, the width of which does not exceed the distance between the two support plates. The area above the front end of the lead screw is the loading and unloading area, which is also where there is a risk of powder falling onto the lead screw. Therefore, the powder-blocking tile is installed to prevent powder from falling onto the lead screw.

[0025] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
