Description

Technical Field

[0001] This utility model relates to the field of screw compressors, and specifically to a screw compressor barrel structure. Background Technology

[0002] On longer screw extruders, the overall torque of the barrel is large due to its length. The current solution is to install a support at the bottom of the barrel to provide support by contacting the contact surface. However, currently, a simple support plate is used. Extruders need to keep the hot melt section warm during extrusion, but conventional extruders do not have this structure. Utility Model Content

[0005] A screw barrel structure includes a barrel, within which a screw driven to rotate by a power source is installed. The screw includes a melting section and further includes...

[0006] A bracket, wherein a clamping plate is provided on the bracket, and a mounting groove is provided on the clamping plate, and the clamping plate has an elastic force to close the mounting groove;

[0007] A rubber collar is fitted onto the circumferential outer wall of the screw and located outside the molten section, and is installed in the mounting groove.

[0008] The mounting groove is a U-shaped groove or a C-shaped groove.

[0009] The collar is provided with an assembly groove, and a temperature sensor is installed in the assembly groove.

[0010] The screw includes a rod body and a screw thread on the rod body. A wear-resistant ring is detachably connected to the screw thread, and the circumferential outer wall of the wear-resistant ring is disposed opposite to the inner wall of the barrel.

[0011] The wear-resistant ring is installed on the front end face of the screw in the feeding direction.

[0012] The wear-resistant ring is mounted on the threaded edge by screws.

[0013] The wear-resistant ring includes a first half-ring and a second half-ring, both of which can be detachably installed on the threaded edge.

[0014] The beneficial effects of this utility model are: This utility model provides a screw barrel structure, which uses a collar to increase the installation area to achieve installation, and also plays a role in heat preservation, achieving multiple benefits and increasing the use effect. Attached Figure Description

[0015] Figure 1 This is a perspective view of one embodiment of the present invention.

[0016] Figure 2 This is a cross-sectional schematic diagram of one embodiment of the present invention.

[0017] Figure 3 This is a partial perspective view of one embodiment of the present invention. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings. A screw barrel structure includes a barrel 1, in which a screw 2 driven to rotate by a power source is installed. The screw includes a melting section and a support 3. The support is provided with a clamping plate 31, and the clamping plate is provided with an installation groove 32. The clamping plate has an elastic force to close the installation groove. A rubber collar 4 is sleeved on the circumferential outer wall of the screw and located outside the melting section, and installed in the installation groove. The structure of the melting section is prior art, and specific details can be found in Chinese Patent CN201511515U. The collar itself is made of rubber, which makes it easier to fit the installation groove, increases the installation area, and makes the installation more stable. In addition, rubber has a certain heat insulation effect, which can keep the barrel opposite the melting section warm.

[0019] In this embodiment, as shown in the figure, the mounting groove is a U-shaped groove or a C-shaped groove. This makes the installation more stable.

[0020] In this embodiment, as shown in the figure, the collar is provided with an assembly groove 41, and a temperature sensor 42 is installed in the assembly groove. This allows the current temperature to be determined, providing a basis for subsequent staged control of pressure and temperature and high-precision machining. The wires of the temperature sensor can be led out through a groove in the inner wall of the collar.

[0021] In this embodiment, as shown in the figure, the screw includes a rod body and a threaded edge 21 on the rod body. A wear-resistant ring 22 is detachably connected to the threaded edge, and the circumferential outer wall of the wear-resistant ring is disposed opposite to the inner wall of the barrel. The wear-resistant ring can be made of materials such as high manganese steel.

[0022] In this embodiment, as shown in the figure, the wear-resistant ring is installed on the front end face of the screw in the feeding direction.

[0023] In this embodiment, as shown in the figure, the wear-resistant ring is mounted on the threaded edge using screws. Screw mounting makes assembly and disassembly convenient.

[0024] In this embodiment, as shown in the figure, the wear-resistant ring includes a first half-ring 221 and a second half-ring 222, both of which can be detachably installed on the threaded edge. The half-ring structure facilitates easy assembly and disassembly.
