When the power element of the machine body is connected to the shaft head 2, the shaft head 2 can be driven to rotate on the mounting bracket 3, and the shaft head 2 provides support for the roller body 1 while transmitting torque to the roller body 1, so that the roller body 1 can stably rotate to extrude materials; a limiting mechanism 5 is arranged on the shaft head 2, and the limiting mechanism 5 is clamped with the roller body 1, and the roller body 1 A flow cavity 11 is coaxially provided on the upper edge, and a cooling pipe head 4 is connected to the flow cavity 11. One end of the cooling pipe head 4 is clamped between the roller body 1 and the shaft head 2, and the other end of the cooling pipe head 4 extends out of the shaft head 2 and is clamped with the mounting bracket 3. The limiting mechanism 5 prevents the shaft head 2 and the roller body 1 from relative movement in the axial direction, thereby ensuring the stability of the connection. At the same time, it ensures that one end of the cooling pipe head 4 in the roller body 1 can maintain stable communication with the flow cavity 11 to prevent leakage, and the difficulty of disassembly and assembly is reduced through the clamping structure.

[0027] A connecting sleeve 21 is provided at one end of the shaft head 2 facing the roller body 1, and the connecting sleeve 21 extends into the roller body 1. A plurality of reinforcing rods 22 are provided at one end of the connecting sleeve 21 in the roller body 1, and the plurality of reinforcing rods 22 are all plugged into the roller body 1. The connection length of the shaft head 2 and the roller body 1 is extended by the connecting sleeve 21 and the reinforcing rods 22, thereby improving the supporting strength of the shaft head 2 to the roller body 1. At the same time, the plurality of reinforcing rods 22 are respectively plugged into the roller body 1, which ensures the connection strength while stably transmitting the torque received by the shaft head 2 to the roller body 1, thereby ensuring the stability of the operation process.

[0028] An inner snap ring 42 is provided at one end of the cooling pipe head 4 inside the roller body 1, and a boss is provided on the inner wall of the connecting sleeve 21. One end of the inner snap ring 42 is in contact with the roller body 1, and the other end is in contact with the boss of the connecting sleeve 21. A sealing ring 6 is installed between the inner snap ring 42 and the roller body 1. When the shaft head 2 is installed into the roller body 1, the inner snap ring 42 is squeezed inwardly so that the two ends of the sealing ring 6 are respectively in contact with the roller body 1 and the inner snap ring 42, thereby achieving sealing and preventing the coolant from leaking from the connection.

[0029] A plurality of movable grooves 23 and mounting grooves 24 are symmetrically provided at one end of the shaft head 2 in the roller body 1. The limiting mechanism 5 is installed in the corresponding movable grooves 23 and mounting grooves 24. The movable groove 23 is provided on the end face of the shaft head 2. The limiting mechanism 5 includes a spring 51, which is installed in the mounting groove 24. A second clamping block 52 is connected to the other end of the spring 51.

The other end of the pry bar 54 extends away from one end of the roller body 1 and is provided in the movable groove 23. The center of the pry bar 54 is rotatably connected to the shaft head 2.

[0030] When the shaft head 2 is inserted into the roller body 1, the second clamping block 52 pops outward under the action of the spring 51 and engages with the clamping groove 12, thereby preventing the shaft head 2 and the roller body 1 from relative displacement in the axial direction, ensuring the stability of the position of the roller body 1 during operation, and at the same time maintaining the sealing ring 6 at both ends to prevent leakage;

[0031] When the shaft head 2 needs to be removed, it is only necessary to move the pry bar 54 so that the other end of the pry bar 54 overcomes the elastic force of the spring 51 and pulls the second block 52 inward out of the slot 12. At this time, the limit mechanism 5 and the roller body 1 are unlocked, and the shaft head 2 can be pulled outward to complete the removal.

[0032] The mounting bracket 3 comprises an upper ring sleeve 31 and a lower ring sleeve 32. The lower ring sleeve 32 is mounted on the machine body.

The outer clamping ring 43 can be connected to the cooling pipe head 4 through a thread. The outer clamping ring 43 can be clamped with the mounting bracket 3. A plurality of clamping blocks 44 are arranged on the outer clamping ring 43. The clamping blocks 44 can be clamped with the lower ring sleeve 32, thereby preventing the cooling pipe head 4 from rotating synchronously when the shaft head 2 rotates, thereby realizing the fixed installation of the cooling pipe head 4 without the need for additional connecting parts.

[0034] During installation of this embodiment, the bearing 7 is first installed on the shaft head 2, and then the sealing ring 6 is installed in the roller body 1, and then the cooling pipe head 4 is inserted into the roller body 1, so that the inner retaining ring 42 is sealed and connected with the sealing ring 6, and then the shaft head 2 is sleeved on the tube body 41, and the reinforcing rod 22 is aligned with the hole in the roller body 1 and inserted into the roller body 1 until the clamping block 2 52 automatically pops outward and engages with the clamping groove 12. At this time, the shaft head 2 cannot move in the axial and circumferential directions, and the connection between the shaft head 2 and the roller body 1 is completed; then the outer retaining ring 43 is installed on the tube body 41, and the roller is assembled as a whole; the upper ring sleeve 31 is opened, and the roller is hoisted and placed into the lower ring sleeve 32, so that a number of clamping blocks 44 are engaged with the preset grooves in the lower ring sleeve 32, and then the upper ring sleeve 31 is closed, and the connecting bolts between the upper and lower sleeves are tightened to complete the installation of the roller as a whole.

[0035] Specifically, the shaft head 2 is connected to the roller body 1 through the connecting sleeve 21 and the reinforcing rod 22, which prolongs the contact length between the shaft head 2 and the roller body 1, and ensures the support stability of the shaft head 2 on the roller body 1. At the same time, a plurality of reinforcing rods 22 are respectively plugged into the roller body 1, which can stably transmit the torque of the shaft head 2 to the roller body 1, and ensure the stability of operation;

[0036] A limiting mechanism 5 is provided on the connecting sleeve 21, and the cooling pipe head 4 is inserted into the roller body 1, and then the shaft head 2 is sleeved on the cooling pipe head 4 and inserted into the hole in the roller body 1. When it is inserted into place, the second block 52 of the limiting mechanism 5 pops out under the action of the spring 51 and engages with the slot 12 on the roller body 1. Finally, the roller is placed on the lower ring sleeve 32 as a whole, and the bolts between the upper replacement sleeve 31 and the lower ring sleeve 32 are locked to complete the installation. When disassembling, the pry bar 54 is moved to pull the second block 52 out of the slot 12, and the shaft head 2 can be pulled out, which can prevent the roller body 1 and the shaft head 2 from relative displacement in the axial direction, ensure the stability of the roller body 1 during operation, and reduce the use of bolts, making it easy to disassemble and operate.
