Description

Technical Field

[0001] The utility model belongs to the technical field of catalyst production, and particularly relates to belt-type gear ball production equipment. Background Art

[0002] In chemical production, scientific experiments and life activities, catalysts are important substances. The performance of catalysts is closely related to the final catalyst indicators, and the appearance of catalysts is also crucial to the performance of catalysts. In recent years, catalyst manufacturers have increased their demand for spherical catalysts (round balls and five-tooth balls). It is found that during the use of spherical catalysts, the bed temperature and resistance drop are better than those of strips and other special-shaped catalysts. In the preparation, manual ball cutting was used at first, and the equipment was later updated to the commonly used automatic ball rubbing equipment. However, with the intensification of competition in the catalyst market, the stacking ratio of catalyst carriers is getting lower and lower, and the pore volume is getting larger and larger. When producing spherical catalysts, the strips are manually turned and sent to the automatic ball rubbing equipment, and the automatic ball rubbing equipment is used to rub the balls. However, for catalysts with low stacking ratios, the strip turning process is very easy to break, which is difficult to adapt to the production of spherical carriers with low stacking ratios.

[0003] In response to the above problems, our company has developed and designed a catalyst carrier ball cutting equipment (publication number CN202320783650.2) to solve the problems existing in the prior art. In actual application, each ball cutting equipment can be used as a production line to produce spherical catalysts, and production efficiency and quality are guaranteed. However, the mold size of the extrusion structure and the ball forming structure in the ball cutting equipment is fixed, so that the equipment can only produce spherical catalyst products of a specific size. This limitation makes the equipment particularly passive when responding to market demand. When order demand changes and requires the production of catalysts of different sizes, the ball cutting equipment cannot meet the demand, resulting in some equipment being idle due to its inability to adapt to new demands. At the same time, when the market demand for catalysts of a certain size surges, the existing fixed-size production lines may face the problem of insufficient production capacity, affecting production efficiency and delivery time.

[0004] Therefore, how to design a new type of gear ball production equipment that can flexibly adjust the mold size and adapt to different production needs has become a technical problem to be solved in the current catalyst production field. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a belt-type gear ball production device that is easy to change molds to solve the above-mentioned problems.

[0006] The utility model discloses a belt-type gear ball production equipment, comprising a vertical extrusion device, a first conveyor belt is arranged below the output end of the vertical extrusion device, a cutting device is mounted on the first conveyor belt, a second conveyor belt perpendicular to the first conveyor belt is arranged at the end of the first conveyor belt, a ball-forming device is arranged below the end of the second conveyor belt, and a third conveyor belt is arranged below the ball-forming device; a mold changing assembly is arranged on the output end of the vertical extrusion device, the ball-forming device comprises a frame, two parallel rotating shafts are arranged in the frame, one end of the two rotating shafts are arranged with meshing gears, a driving mechanism for driving any rotating shaft to rotate is arranged on the frame, a cutting roller sleeve is respectively sleeved on the two rotating shafts, a plurality of annular semicircular grooves are arranged in an array on the cutting roller sleeve, a locking mechanism is arranged between the cutting roller sleeve and the rotating shaft, and an opening is arranged on one side of the frame.

On this basis, a die changing assembly 7 that can switch the extrusion die is arranged at the output end of the vertical extrusion device 1, so as to control the size of the extruded strips. The ball-forming device 5 includes a frame 8, in which two parallel rotating shafts 9 are arranged, and one end of the two rotating shafts 9 is provided with a meshing gear 10. The frame 8 is provided with a driving mechanism 11 for driving any rotating shaft 9 to rotate, and the two rotating shafts 9 are respectively provided with a cutting roller sleeve 12, and the cutting roller sleeve 12 is provided with a plurality of annular semicircular grooves 13 in an array, and a locking mechanism is provided between the cutting roller sleeve 12 and the rotating shaft 9, and an opening is provided on one side of the frame 8.

[0023] The preferred technical solution in this embodiment is as follows Figure 3As shown in , the die changing assembly 7 includes a hydraulic telescopic rod 14, a plug plate 15 is provided on the telescopic end of the hydraulic telescopic rod 14, and a plurality of forming dies 17 are provided on the plug plate 15. A slot 16 adapted to the plug plate 15 is provided on the output end of the vertical extrusion device 1, so that the plug plate 15 can be accurately inserted into the slot 16. By controlling the extension length of the telescopic end of the hydraulic telescopic rod 14, different forming dies 17 can be aligned with the output end of the vertical extrusion device 1, and strip materials of corresponding sizes can be extruded.

[0024] The preferred technical solution in this embodiment is as follows Figures 4 to 6 As shown in , in order to ensure that the cutting roller sleeve 12 will not fall off or shift when rotating at high speed, and also to facilitate the rapid replacement of the cutting roller sleeve 12 of different molding sizes according to production requirements, the locking mechanism includes a nut 18, the middle end of the rotating shaft 9 is set as a hollow spline shaft, and the cutting roller sleeve 12 is provided with a spline groove adapted to the spline shaft.

A limiting step 19 adapted to the cutting roller sleeve 12 is provided at one end of the gear 10 of the rotating shaft 9, which is used to limit the axial movement of the cutting roller sleeve 12. A retaining ring 20 abutting against the cutting roller sleeve 12 is sleeved on the other end of the rotating shaft 9. The nut 18 is screwed on the rotating shaft 9 and abuts against the retaining ring 20. By tightening the nut 18, pressure is generated between the retaining ring 20 and the cutting roller sleeve 12, thereby achieving a firm locking of the cutting roller sleeve 12. This design ensures the stability and safety of the cutting roller sleeve 12 when rotating at high speed.

[0025] In the preferred technical solution of this embodiment, a plurality of air holes 21 are provided on the rotating shaft 9. These air holes 21 enable the heat generated by the friction between the cutting roller sleeve 12 and the hollow spline shaft due to the tolerance clearance to be discharged in time during the operation of the equipment, so as to prevent the normal operation of the equipment from being affected by overheating. In addition, these air holes 21 are also used to reduce the air tightness between the hollow spline shaft and the cutting roller sleeve 12, so as to facilitate the disassembly and assembly of the cutting roller sleeve 12.

[0026] In the preferred technical solution of this embodiment, the third conveyor belt 6 is a skirt conveyor belt.

[0027] The preferred technical solution in this embodiment is as follows Figure 5 As shown in FIG. 8 , a hopper 22 is provided on the top of the frame 8 .

[0028] The usage and principle of this utility model:

[0029] First, the raw material is extruded through the vertical extruder 1 to form a continuous toothed strip material. This step is the starting point of the production process, ensuring that the raw material is evenly and continuously extruded into the required strip shape.

[0030] Next, the strip material is smoothly conveyed by the first conveyor belt 2 and reaches the cutting device 3. The cutting device 3 accurately cuts the strip material into equal length material segments according to the preset length requirements. This step ensures the consistency of the length of the material segments in the subsequent processing process.

[0031] The cut material segments are then vertically conveyed to the pelletizing device 5 by the second conveyor belt 4. In the pelletizing device 5, two parallel rotating shafts 9 are respectively provided with cutting roller sleeves 12, and a plurality of annular semicircular grooves 13 are arranged in an array on these cutting roller sleeves 12. When the material segments pass through, the two cutting roller sleeves 12 rotate synchronously through the meshing of the gears 10, and the semicircular grooves 13 are used to cut the material segments into spherical catalysts with toothed structures. This step is the core process of producing toothed ball catalysts, and the shape and quality of the toothed ball catalysts are ensured through precise design and operation.

[0032] Finally, the formed tooth ball product is conveyed to the designated location by the third conveyor belt 6. Since the tooth ball product may have rolling properties, in order to prevent it from rolling down, the third conveyor belt 6 adopts a skirt conveyor belt design. This design effectively solves the problem of the tooth ball product rolling down and ensures the smooth conveyance and collection of the product.

[0033] The entire belt-type gear ball production equipment realizes efficient and stable production from raw materials to gear ball products through the coordinated work of the above steps and components, meeting the needs of different industries for gear ball products.
