Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a hanging ultrafine crusher. Background Art

[0002] An ultrafine crusher is a high-performance device that can crush materials to the micron or even nanometer level, and is widely used in the fields of food, chemical industry, medicine, minerals, ceramics, new materials, etc. Its working principle is to use a high-speed rotating hammer head, blade or air flow, etc., to generate strong impact, shear and friction forces on the materials, so that the material particles are quickly refined. The ultrafine crushing technology can significantly increase the specific surface area of the materials and enhance their physical and chemical activities, which plays an important role in improving product performance and production efficiency.

[0003] The Chinese utility model patent publication number CN216856982U discloses a hanging ultrafine crusher. The feeding process is as follows: the material inlet of the crushing cylinder faces downward, and the locking cylinders on both sides of the material inlet are in the extended state. Place the material box on the placement plate, move it along the slide rail to the top plate. The material box is within the range of the locking cylinder. Operate the feeding cylinder to extend upward. The top plate lifts the material box and docks it to the material inlet. The locking cylinder retracts to press the material box tightly on the material inlet to complete the feeding. After the crushing cylinder rotates 180°, the crushing and grinding operation can be carried out. It relies on the feeding cylinder and the top plate to realize the lifting of the material box. Since the cylinder supports the bottom of the material box and the cylinder itself has a relatively high height, the height for manual handling of the material box up and down is relatively high and laborious; and when the material box is placed on the top plate and the top plate is at the lowest height, the height of the material box is relatively high, which indirectly increases the height of the frame. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a hanging ultrafine crusher.

[0005] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0006] A hanging ultrafine crusher includes a frame, a crushing cylinder installed on the frame through a suspension rope, a material box installed on the feed inlet of the crushing cylinder, a guide rail at the lower end of the frame, and a support plate that is slidably installed on the guide rail and used to place the material box; two sets of servo electric cylinders for lifting the support plate are arranged at the lower end of the frame. The upper parts of the opposite sides of the material box are provided with support plates, and two sets of servo electric cylinders for lifting the support plates are arranged at the lower end of the frame.

[0007] Preferably, a tapered groove is provided at the lower end of the support plate, and a chamfer adapted to the groove is provided at the end of the lead screw of the servo electric cylinder.

[0008] Preferably, the upper end of the material box has a lip, and positioning holes are provided on the lip. Positioning pins adapted to the positioning holes are provided on the feed inlet of the crushing cylinder; the positioning pins are in a tapered shape or a spherical shape.

[0009] Preferably, there are two positioning holes, which are arranged along the diagonal of the cartridge case.

[0010] Preferably, inclined stoppers are provided on the four sides of the pallet.

[0011] Preferably, a U-shaped handle is provided at one end of the pallet facing the operator, and the U-shaped handle extends a certain distance in the direction facing the operator.

[0012] Preferably, weight-reducing holes are provided on the pallet.

[0013] Adopting the above technical solution, the following advantages are achieved:

[0014] (1) Without changing the original lifting stroke of the cartridge case, the present utility model significantly reduces the ground clearance of the cartridge case when it descends to the lowest position. This improvement effectively optimizes the operation experience of manually handling the cartridge case. That is, when the cartridge case is at the lowest position, it can be closer to the ground, thus greatly reducing the physical burden of the operator when lifting and lowering the cartridge case, and improving the safety and comfort of the operation. Correspondingly, the overall height of the frame is reasonably reduced, further enhancing the stability of the equipment and reducing the potential safety hazards caused by too high a center of gravity. At the same time, the reduction of the frame height not only reduces the use of materials and the self-weight of the equipment, but also indirectly promotes the material saving and transportation convenience, meeting the pursuit of environmental protection, energy conservation and high efficiency in modern manufacturing.

[0015] (2) The present utility model adopts two sets of symmetrically configured servo electric cylinders to perform the lifting action of the cartridge case, effectively improving the stability and reliability during the lifting process of the cartridge case. Through the symmetrically arranged servo electric cylinders, it can be ensured that the cartridge case is evenly stressed when rising or falling, avoiding the inclination or shaking phenomenon that may occur in the traditional single-point drive mode, thus greatly improving the operation accuracy and smoothness.

[0016] (3) In order to further ensure the accurate docking between the cartridge case and the crushing cylinder, the present utility model also designs positioning holes on the cartridge case. These positioning holes are precisely matched with the positioning pins on the crushing cylinder. When the cartridge case rises to the in-place position, the positioning holes and the positioning pins are automatically engaged, thus realizing the rapid and accurate docking between the cartridge case and the crushing cylinder. This design not only simplifies the operation process and improves the work efficiency, but also effectively avoids problems such as material leakage or equipment damage caused by inaccurate docking, greatly ensuring the continuity of the production process and the quality consistency of the products.
