Description

Technical Field

[0001] This utility model belongs to the field of dry powder press technology, and specifically provides a dry powder press with vibration anti-clogging function. Background Technology

[0002] Traditional dry powder presses are widely used in powder metallurgy, ceramic molding, and pharmaceutical industries to press dry powder materials into products of specific shapes. However, existing dry powder presses have significant drawbacks in long-term use. Existing equipment often lacks effective anti-clogging mechanisms, and dry powder in the discharge trough easily forms lumps, causing poor or interrupted discharge. Simultaneously, uneven distribution of dry powder is a prominent problem when filling the mold cavity. Traditional uniform distribution mechanisms have limited coverage and struggle to reach the corners and edges of the cavity, resulting in density differences, shape defects, or uneven surfaces in the molded products, reducing product yield and consistency. Therefore, a dry powder press with vibration anti-clogging function is needed. Utility Model Content

[0003] To solve the above problems, this utility model provides a dry powder press with vibration anti-clogging function.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a dry powder press with vibration anti-clogging function, including a base plate and a material box. The material box is mounted on the base plate by a power device. A discharge cavity is opened on the lower surface of the material box. A power mechanism is installed in the discharge cavity. A uniform distribution mechanism is evenly fixedly installed on the rotation output end of the power mechanism. A discharge groove is opened on the upper surface of the inner cavity of the discharge cavity. An anti-caking mechanism matching the discharge groove is installed in the discharge cavity.

[0005] The anti-caking mechanism includes a mounting plate and a motor. The mounting plate is fixedly installed on the inner wall of the discharge chamber. A vibrator is fixedly installed on the outer wall of the mounting plate and embedded in the side wall of the discharge chamber. A shell is fixedly installed on the inner wall of the mounting plate. Blades are uniformly fixedly installed inside the shell and fit against the opening of the discharge trough. The motor is fixedly installed in the discharge trough, and a main shaft is fixedly installed at the output end of the motor. A spiral conveyor plate is fixedly installed on the outer wall of the main shaft.

[0006] Furthermore, the helical pitch of the spiral feeder plate near the motor is greater than the helical pitch of the spiral feeder plate near the cutter body.

[0007] Furthermore, the power mechanism includes a fixed shell, which is fixedly installed in the discharge chamber. A power motor is fixedly installed on the upper surface of the fixed shell. A motor storage cavity is opened in the inner wall of the discharge chamber, and the power motor is located in the motor storage cavity. A rotating plate located in the fixed shell is fixedly installed at the output end of the power motor. A rotating shaft is fixedly installed in the middle of the lower surface of the rotating plate. An inner uniformly distributed plate is evenly fixedly installed on the lower side of the outer wall of the rotating shaft.

[0008] Furthermore, the uniform distribution mechanism includes an arc-shaped cylinder, a connecting rod is fixedly installed on the upper side of the outer wall of the arc-shaped cylinder, and the connecting rod is fixedly installed on the lower surface of the rotating plate. One end of a spring is fixedly installed on the inner wall of the arc-shaped cylinder, and a push plate is fixedly installed on the other end of the spring. The push plate is movably assembled inside the arc-shaped cylinder.

[0012] The beneficial effects of using this utility model are:

[0013] This invention features an anti-caking mechanism that combines a vibrator and a spiral conveyor plate to effectively solve the problem of dry powder clumping. The vibrator generates high-frequency vibrations, which disperse the dry powder on the blades. The variable spacing of the spiral conveyor plate optimizes the conveying process, ensuring smooth drop of the dry powder and reducing the amount of fine particles.

[0024] 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.

[0025] Reference Figures 1 to 7 A dry powder press with vibration anti-clogging function includes a base plate 1 and a material box 2. The material box 2 is mounted on the base plate 1 by a power device. A discharge chamber 21 is opened on the lower surface of the material box 2. A power mechanism 4 is installed in the discharge chamber 21. A uniform distribution mechanism 5 is evenly fixedly installed on the rotation output end of the power mechanism. A discharge groove 22 is opened on the upper surface of the inner cavity of the discharge chamber 21. An anti-caking mechanism 3 matching the discharge groove 22 is installed in the discharge chamber 21.

[0026] A power device, which can be hydraulic or electric, is installed on the left end of the base plate 1 to move the material box 2; the material box 2 is placed in the middle, and a feeding port (not shown in the figure) is provided on the material box 2; a mold is installed on the right end, and a power structure is provided to control the lifting and pressing of the upper mold. Figure 1 This is a schematic diagram of the pressure application process.

[0027] The discharge chamber 21 has the same shape as the mold cavity. The power mechanism 4 and the uniform distribution mechanism 5 operate under the constraint of the inner wall of the discharge chamber 21 to achieve uniform distribution of dry powder on the surface of the cavity.

[0028] The anti-caking mechanism 3 is connected to the dry powder storage box inside the material box 2, and is used to crush and vibrate the dry powder to prevent it from clumping.

[0029] Under the combined action of the anti-caking mechanism 3, the power mechanism 4, and the uniform distribution mechanism 5, the dry powder is evenly distributed in the cavity, ensuring that the final molded product has a complete shape and meets quality standards.

[0030] The anti-caking mechanism 3 includes a mounting plate 31 and a motor. The mounting plate 31 is fixedly installed on the inner wall of the discharge chamber 21. A vibrator is fixedly installed on the outer wall of the mounting plate 31 and embedded in the side wall of the discharge chamber 21. A housing 32 is fixedly installed on the inner wall of the mounting plate 31. A blade 33 is uniformly fixedly installed inside the housing 32 and fits against the opening of the discharge trough 22. The motor is fixedly installed inside the discharge trough 22, and a main shaft 34 is fixedly installed at the output end of the motor. A spiral conveyor plate 35 is fixedly installed on the outer wall of the main shaft 34.

[0031] Specifically, the pitch of the spiral feed plate 35 near the motor is greater than the pitch of the spiral feed plate 35 near the cutter body 33.

[0032] The side wall of the discharge trough 22 has a hole, and a conveying pipe is installed in the hole. The conveying pipe is connected to the dry powder storage box in the material box 2, and the connected part is equipped with a drying structure. The motor drives the spiral conveying plate 35 to rotate, and the dry powder is conveyed to the discharge chamber 21 through the spiral conveying plate 35. The structural design of the spiral conveying plate 35 makes it easy to feed and convey at the upper end with a large spacing, and can squeeze the dry powder to a certain extent at the lower end with a small spacing to crush the small particles. The spiral spacing of the spiral conveying plate 35 needs to be calculated and designed to avoid excessive extrusion pressure that makes the dry powder too compact.

[0033] The vibrator causes the mounting plate 31, the outer casing 32 and the blade 33 to vibrate. When the dry powder is delivered to the blade 33, the vibrating blade 33 will cause the dry powder to disperse and fall, so that it can be pushed and evenly distributed by the distribution mechanism 5 later.

[0034] The number and distribution of the discharge trough 22 and the anti-caking mechanism 3 can be adjusted according to the actual situation.

[0035] Specifically, the power mechanism 4 includes a fixed housing 41, which is fixedly installed in the discharge chamber 21. A power motor 42 is fixedly installed on the upper surface of the fixed housing 41. A motor storage chamber is opened in the inner wall of the discharge chamber 21, and the power motor 42 is located in the motor storage chamber. A rotating plate 43 located in the fixed housing 41 is fixedly installed at the output end of the power motor 42. A rotating shaft 44 is fixedly installed in the middle of the lower surface of the rotating plate 43. An inner uniformly distributed plate 45 is evenly fixedly installed on the lower side of the outer wall of the rotating shaft 44.

[0036] The power mechanism 4 mainly drives the rotating plate 43 to rotate through the power motor 42, which in turn drives the rotating shaft 44 and the uniform distribution mechanism 5 to rotate, thus completing the work of uniformly distributing dry powder.

[0037] Specifically, the uniform distribution mechanism 5 includes an arc-shaped cylinder 51. A connecting rod 52 is fixedly installed on the upper side of the outer wall of the arc-shaped cylinder 51, and the connecting rod 52 is fixedly installed on the lower surface of the rotating plate 43. One end of a spring 53 is fixedly installed on the inner wall of the arc-shaped cylinder 51, and a push plate 54 is fixedly installed on the other end of the spring 53. The push plate 54 is movably assembled inside the arc-shaped cylinder 51. A telescopic plate 55 is fixedly installed on the outer wall of the push plate 54, and an outer uniform distribution plate 56 is fixedly installed on the lower surface of the outer end of the telescopic plate 55.

[0038] Specifically, the outer end of the telescopic plate 55 is rotatably equipped with a roller 57, and the outer wall of the roller 57 is in contact with the side wall of the discharge chamber 21.

[0039] Specifically, guide plates 58 are symmetrically fixedly installed on the lower side of the outer wall of the arc-shaped cylinder 51, and outer uniformly distributed plates 56 are inserted between the guide plates 58.

[0040] The spring 53 inside the uniform distribution mechanism 5 is always in a compressed state. The telescopic plate 55 and the outer uniform distribution plate 56 are in contact with the side wall inside the discharge cavity 21 through the rollers. During the rotation of the rotating plate 43, the uniform distribution mechanism 5 is driven to rotate. At the same time, under the elastic force of the spring 53, the roller 57 is always in contact with the inner wall of the discharge cavity 21, so that the outer uniform distribution plate 56 can pass through the corner of the cavity and complete the dry powder filling at this point.

[0041] The arc-shaped cylinder 51, the telescopic plate 55, and the outer uniform distribution plate 56 are designed in an arc shape, which can better promote the uniform distribution of dry powder.

[0042] Specifically, the number of inner uniformly distributed plates 45 and outer uniformly distributed plates 56 are equal, and the inner uniformly distributed plates 45 and outer uniformly distributed plates 56 are staggered.

[0043] The inner distribution plate 45 is used to achieve uniform distribution of dry powder on the inner side of the outer distribution plate 56. When the outer distribution plate 56 is in the outermost position, the radius of the inner end running trajectory of the outer distribution plate 56 is smaller than the radius of the outer end running trajectory of the inner distribution plate 45, so that all the dry powder can be evenly distributed, making the surface of the distributed dry powder flat, and ensuring the integrity of the product shape after pressure molding.

[0044] The inner end of the uniform distribution plate 45 can extend to the axis of the rotating shaft 44 to further improve the uniformity effect.

[0045] When this dry powder press is working, the upper mold is in the upper position. The power equipment pushes the material box 2 to the right until the discharge chamber 21 is directly on the cavity. Then, the dry powder is put in through the anti-caking mechanism 3. At the same time, the power motor 42 runs, driving the inner uniform distribution plate 45 and the outer uniform distribution plate 56 to rotate to complete the uniform distribution of the dry powder. After completion, the material box 2 is reset, the upper mold moves down to apply pressure, and after completion, the product is ejected from the cavity through the ejection mechanism under the bottom plate 1, so that the next operation can be carried out. In the next operation, the movement of the material box 2 pushes the product to the right to the placement box located on the right side of the bottom plate 1. The ejection mechanism is reset only after the product is pushed away.

[0046] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of this utility model. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this utility model.
