[0002] The patent document with Chinese patent application number CN201310400351.7 discloses a technical solution named "extrusion cylinder assembly replacement device", which includes the following technical features: an electric cylinder and a clamping part, the electric cylinder includes an electric cylinder support, an electric cylinder body and an output shaft, the clamping part is connected to the output shaft through a connecting part, the connecting part includes a rod body, and a clamping piece and a fixing plate respectively fixed to the two ends of the rod body, the clamping piece is clamped at the end of the output shaft and is loosely connected through a pin shaft and a cotter pin, and the two ends of the clamping part also have a boss, and the extrusion cylinder assembly replacement device also includes a guide block. The clamping part is connected to the output shaft and can move linearly with the output shaft. When the clamping part moves to disengage from the groove on the outer periphery of the extrusion cylinder assembly, the extrusion cylinder assembly replacement device is in a loose state, and the extrusion cylinder assembly can be disengaged from the extrusion cylinder device; when the clamping part moves to contact with the groove of the extrusion cylinder assembly, the extrusion cylinder assembly replacement device is in a clamping state, and the extrusion cylinder assembly is clamped to the extrusion cylinder shell.

[0021] like Figures 1 to 3 As shown, the utility model describes an extrusion cylinder structure used in an extruder, comprising an extrusion cylinder body 1, on the outer circumferential surface of which a convex retaining ring 11 and a T-shaped clamping groove 12 are respectively provided, in which at least one detachable retaining block 2 is embedded, and a clamping groove 10 is reserved between the retaining block 2 and the convex retaining ring 11.

[0022] In the extrusion cylinder structure, a convex retaining ring 11 and a T-shaped clamping bracket 12 are respectively provided on the outer circumferential surface of the extrusion cylinder body 1, and at least one detachable retaining block 2 is embedded in the T-shaped clamping bracket 12, and a clamping groove 10 is reserved between the retaining block 2 and the convex retaining ring 11. In this way, when installing the extrusion cylinder structure, the clamping groove 10 can be used to achieve clamping positioning. Because the clamping groove 10 is reserved between the retaining block 2 and the convex retaining ring 11, and the retaining block 2 is detachably embedded in the T-shaped clamping bracket 12, it is convenient to quickly realize the installation and removal of the retaining block 2, and the T-shaped clamping bracket 12 can also play a very good role in limiting and supporting the retaining block 2, so that the retaining block 2 can be stably installed, and the reliability of the extrusion cylinder structure is very high. Such an extrusion cylinder structure can facilitate the installation and positioning of the extrusion cylinder through very few components, which can not only help reduce consumables, but also reduce manufacturing difficulty and manufacturing costs, and improve manufacturing efficiency. The applicability of the extrusion cylinder structure is very strong.

[0023] like Figure 4 As shown, the length direction of the T-shaped clamping bracket 12 is in the same direction as the circumferential direction of the extrusion cylinder body 1, and the two ends of the T-shaped clamping bracket 12 are respectively placed on the left and right side walls of the extrusion cylinder body 1, and an inlet and outlet notch 13 for the retaining block 2 to enter and exit is opened in the middle of the T-shaped clamping bracket 12, and retaining blocks 2 are respectively embedded in the two ends of the T-shaped clamping bracket 12. This not only facilitates the installation of the retaining block 2, but also facilitates a more reliable clamping effect, thereby helping to further improve the reliability and applicability of the extrusion cylinder structure.

[0024] like Figure 3 and Figure 4 As shown, the inner end of the retaining block 2 is an arc-shaped embedding head 21 matching the T-shaped clamping bracket 12, and the arc-shaped embedding head 21 is slidably embedded in the T-shaped clamping bracket 12, and the arc-shaped embedding head 21 can enter and exit the T-shaped clamping bracket 12 through the entry and exit notch 13. This not only facilitates the assembly and disassembly of the retaining block 2, but also ensures that the retaining block 2 can play a stable clamping role.

[0025] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a positioning protrusion 14 is provided on the top surface of the extrusion cylinder body 1. The positioning protrusion 14 can be used to accurately position the upper and lower ends and the left and right ends of the extrusion cylinder structure, thereby helping to improve the accuracy and stability of the installation and positioning of the extrusion cylinder structure, and further enable the two ends of the T-shaped clamping bracket 12 to more stably support the two retaining blocks 2, which can facilitate the two retaining blocks 2 to play a very stable clamping role, which helps to further improve the reliability of the extrusion cylinder structure.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the positioning protrusion 14 is a convex strip extending along the axial direction of the extrusion cylinder body 1. This enables the positioning protrusion 14 to have a more stable and reliable positioning effect, thereby helping to further improve the reliability of the extrusion cylinder structure.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, at least one lifting screw hole 141 is provided on the positioning protrusion 14, and the lifting screw hole 141 penetrates the extrusion cylinder body 1. The lifting screw hole 141 can be screwed with a lifting eye screw, so that the extrusion cylinder structure can be lifted by a lifting device, thereby helping to further improve the convenience of assembly and disassembly.

[0028] like Figure 1 and Figure 2 As shown, a through hole 22 penetrating into the clamping groove 10 is provided on the outer wall of the retaining block 2. The through hole 22 can be penetrated by a screw, so that the retaining block 2 can be conveniently fixed on the extrusion cylinder seat by the screw, which can help the retaining block 2 to position the column extrusion cylinder structure more stably, thereby helping to further improve the reliability of the extrusion cylinder structure.

[0029] like Figure 2 As shown, the through hole 22 is a countersunk hole, and the small end of the through hole 22 faces the side of the clamping groove 10. In this way, the screws fixing the extrusion cylinder structure can be hidden, which is convenient for hiding the nut end of the screw, thereby reducing the space occupied and reducing scratches, and further helping to further improve the applicability of the extrusion cylinder structure.

[0030] like Figure 5 and Figure 6 As shown, during the actual installation, a through-mounting hole 201 is provided on the extrusion cylinder seat 20, and a positioning convex ring 202 is provided on the opening of the mounting hole 201. A positioning groove 203 matching the positioning convex portion 14 is provided on the hole wall of the mounting hole 201, and the positioning groove 203 penetrates the positioning convex ring 202. The extrusion cylinder structure is embedded in the mounting hole 201, and the positioning convex portion 14 is embedded in the positioning groove 203, and the convex retaining ring 11 is pressed against the positioning convex portion 14. The inner end surface of the convex ring 202 is arranged, and the T-shaped clamping bracket 12 is located outside the mounting hole 201; then the retaining block 2 is embedded in the T-shaped clamping bracket 12, and the retaining block 2 is attached to the outer end surface of the positioning convex ring 202 and the outer wall of the extrusion cylinder seat 20, at this time, the clamping groove 10 is just clamped on the positioning convex ring 202; then the screw 30 is arranged in the through hole 22, and the threaded end of the screw 30 passes through the through hole 22 and is screwed to the positioning convex ring 202 or / and the extrusion cylinder seat 20. In this way, the installation of the extrusion cylinder structure can be met.
