It is mainly used to press various powdered raw materials into cylindrical pellets to meet the requirements of storage, transportation and feeding. The ring die is a part that is easily worn and frequently disassembled during the production process of the pellet mill. How to quickly disassemble and replace it is an important topic that needs to be studied.

[0003] At present, most of the ring die pelletizing machines on the market use clamps to clamp the ring die and the transmission wheel. When removing the ring die, the clamp must be removed first. It is not difficult to remove the clamp for small models, but it takes a lot of time and manpower to remove a whole set of clamps for some large models, and frequent repeated loading and unloading will affect the life of the equipment itself.

[0004] Therefore, it is necessary to design a connection structure between the ring die and the transmission wheel of a pelletizer to solve the above problems. Utility Model Content

[0006] The technical solution of the utility model is: a connecting structure between a ring die and a transmission wheel of a pelletizer, comprising a transmission wheel and a ring die abutting against the transmission wheel; the connection between the transmission wheel and the ring die is locked by a plurality of hoops arranged along the circumferential direction; an adjusting mechanism connected to the transmission wheel is provided in the middle of the hoops; locking pieces connected to the transmission wheel are provided at both ends of the hoops; the adjusting mechanism is used to lift or press down the hoops, and when the hoops are lifted, the locking of the transmission wheel and the ring die is released; when the hoops are pressed down, the transmission wheel and the ring die are locked.

[0007] A clamping groove is provided in the middle of the clamping hoop for the end of the driving wheel and the end of the ring die to extend into, and the inner walls on both sides of the clamping groove are in contact with the end of the driving wheel and the end of the ring die through inclined surfaces respectively.

[0008] The adjustment mechanism includes a fixing sleeve fixedly connected to the transmission wheel; an adjusting sleeve is threadedly connected to the outer side of the fixing sleeve; a pressure-applying portion is provided on the top of the adjusting sleeve; a through hole for the adjusting sleeve to extend into is provided in the middle of the clamp; an upper bearing ring is provided on the adjusting sleeve between the pressure-applying portion and the top surface of the clamp; the bottom of the adjusting sleeve extends out of the through hole of the clamp, and a lower bearing ring is provided at the bottom where the adjusting sleeve extends; the outer diameters of the upper bearing ring and the lower bearing ring are both larger than the aperture of the through hole of the clamp.

[0009] The fixing sleeve is fixed on the transmission wheel by a first locking screw.

[0010] A limiting clamping spring is provided at the bottom of the adjusting sleeve to prevent the lower bearing ring from falling off.

[0011] The locking member comprises a second locking screw; the second locking screw passes through the clamp and is connected to the transmission wheel.

[0012] By adopting the above technical scheme, the utility model has the following beneficial effects: the utility model locks the ring die and the transmission wheel by means of a plurality of hoops arranged along the circumferential direction, and an adjusting mechanism connected to the transmission wheel is arranged in the middle of the hoops, and the lifting and pressing down of the hoops are adjusted by the adjusting mechanism, thereby realizing the locking and unlocking between the ring die and the transmission wheel.

[0020] (Example 1)

[0021] See Figures 1 to 4 The connection structure between the ring die and the transmission wheel of a pelletizer of the present embodiment comprises a transmission wheel 1 and a ring die 2 abutting against the transmission wheel 1; the connection between the transmission wheel 1 and the ring die 2 is locked by a plurality of hoops 3 arranged along the circumferential direction; an adjusting mechanism 4 connected to the transmission wheel 1 is provided in the middle of the hoops 3; locking members 5 connected to the transmission wheel 1 are provided at both ends of the hoops 3; the adjusting mechanism 4 is used to lift or press down the hoops 3, and when the hoops 3 are lifted, the locking of the transmission wheel 1 and the ring die 2 is released; when the hoops 3 are pressed down, the transmission wheel 1 and the ring die 2 are locked.

[0022] Furthermore, a slot is provided in the middle of the clamp 3 for the ends of the transmission wheel 1 and the ring die 2 to extend into, and the inner walls on both sides of the slot are in contact with the ends of the transmission wheel 1 and the ring die 2 through inclined surfaces, thereby ensuring that the clamp 3 has an extrusion force on the transmission wheel 1 and the ring die 2 when pressed down, making the connection between the transmission wheel 1 and the ring die 2 more stable and firm.

[0023] Furthermore, the adjusting mechanism 4 includes a fixing sleeve 4-1 fixedly connected to the transmission wheel 1; the outer side of the fixing sleeve 4-1 is threadedly connected to an adjusting sleeve 4-2; a pressurizing portion 4-3 is provided on the top of the adjusting sleeve 4-2 to facilitate driving the adjusting sleeve 4-2; a through hole is provided in the middle of the clamp 3 for the adjusting sleeve 4-2 to extend into; an upper bearing ring 4-4 ​​is provided on the adjusting sleeve 4-2 between the pressurizing portion 4-3 and the top surface of the clamp 3; the bottom of the adjusting sleeve 4-2 extends out of the through hole of the clamp 3, and a lower bearing ring 4-5 is provided at the bottom where the adjusting sleeve 4-2 extends; the outer diameters of the upper bearing ring 4-4 ​​and the lower bearing ring 4-5 are both larger than the aperture of the through hole of the clamp 3.

[0024] Furthermore, in order to facilitate the installation of the fixing sleeve 4 - 1 , the fixing sleeve 4 - 1 is fixed to the transmission wheel 1 by a first locking screw 4 - 6 .

[0025] Furthermore, a limiting spring 4-7 is provided at the bottom of the adjusting sleeve 4-2 to prevent the lower bearing ring 4-5 from being separated, so that the installation of the lower bearing ring 4-5 is more convenient.

[0026] Preferably, the locking member 5 includes a second locking screw; the second locking screw passes through the clamp 3 and is connected to the transmission wheel 1.

[0027] The ring die 2 and the transmission connection mechanism of the pelletizer of this embodiment lock the ring die 2 and the transmission wheel 1 through a plurality of hoops 3 arranged along the circumferential direction, and an adjusting mechanism 4 connected to the transmission wheel 1 is arranged in the middle of the hoop 3, and the lifting and pressing down of the hoop 3 are adjusted by the adjusting mechanism 4, so as to realize the locking and unlocking between the ring die 2 and the transmission wheel 1. The hoop 3 does not need to be removed during the adjustment process, which makes the disassembly between the ring die 2 and the transmission wheel 1 more convenient, saving a lot of time and manpower and material resources. At the same time, since the hoop 3 does not need to be disassembled and assembled many times, the service life of the hoop 3 is improved.

[0028] The working principle of this embodiment is as follows: first, when the ring die 2 is not installed, the hoop 3 is in a lifted state. When the ring die 2 is installed, after the ring die 2 is docked with the transmission wheel 1, the adjusting sleeve 4-2 is rotated by the pressurizing part 4-3, so that the upper bearing ring 4-4 ​​drives the hoop 3 to descend, so that the internal groove of the hoop 3 is stuck on the ends of the ring die 2 and the transmission wheel 1, and the hoop 3 locks the ring die 2 and the transmission wheel 1 through the inclined surface; when the ring die 2 is removed, the adjusting sleeve 4-2 is rotated in the opposite direction by the pressurizing part 4-3, so that the lower bearing ring 4-5 drives the hoop 3 to lift, and when the inclined surface of the internal groove of the hoop 3 is separated from the inclined surfaces of the ring die 2 and the transmission wheel 1, the ring die 2 can be removed. The entire installation and disassembly process is very simple, saving a lot of time and manpower and material resources.
