Screw machine barrel structure

Abstract

The utility model discloses a screw machine barrel structure. Mainly solves the problem that the overall size of a machine barrel is increased by one circle and the machine barrel is very bloated because the outer wall of the machine barrel is coated with an externally-arranged heating assembly adopted at present. The machine is characterized in that an opening groove (25) is formed in the axial side wall of the machine barrel, a heater (22) is arranged in the opening groove, the machine further comprises a top cover (3) detachably connected with the machine barrel, the top cover covers the opening groove, and a plurality of through holes (31) for electric wires of the heater to penetrate through are formed in the top cover. According to the screw machine barrel structure provided by the utility model, the heater is arranged in the machine barrel, so that the structure is compact.

Description

Technical Field

[0001] The utility model relates to the field of screw machines, in particular to a screw barrel structure. Background Art

[0002] In order to better realize the function of screw extruder when extruding materials, it is sometimes necessary to heat. The conventional method currently used is to wrap the external heating component on the outer wall of the barrel, which makes the overall size of the barrel larger and very bloated. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the utility model provides a screw barrel structure, which mainly solves the problem that the currently used external heating component is coated on the outer wall of the barrel, which makes the overall size of the barrel larger and very bloated.

[0004] The technical solution of the utility model is:

[0005] A screw barrel structure comprises a screw and a barrel, wherein a material cavity is arranged in the barrel, at least part of the screw is arranged in the material cavity, an axial side wall of the barrel is provided with an open groove, a heater is arranged in the open groove, and a top cover detachably connected to the barrel is included, the top cover covers the open groove, and the top cover is provided with a plurality of through holes for the wires of the heater to pass through.

[0006] A sealing ring is arranged on the inner wall of the through hole, and the sealing ring is used for sealingly cooperating with the electric wire of the heater.

[0007] The inner wall of the opening groove is provided with a baffle, and the baffle divides the opening groove into three chambers with equal volumes.

[0008] The top cover is connected to the baffle plate via screws.

[0009] The sealing ring is made of rubber.

[0010] The beneficial effects of the utility model are as follows: the utility model provides a screw barrel structure, the heater is arranged in the opening groove of the barrel instead of the outer wall of the barrel, and the structure is compact. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, a screw barrel structure includes a screw and a barrel 2, a material cavity 21 is provided in the barrel, at least part of the screw is provided in the material cavity, an opening groove 25 is provided on the axial side wall of the barrel, a heater 22 is provided in the opening groove, and a top cover 3 detachably connected to the barrel is provided, the top cover covers the opening groove, and the top cover is provided with a plurality of through holes 31 for the wires of the heater to pass through. When in use, the top cover is removed, the heater (conventional technology) is placed in the opening groove, and then the top cover is installed, and the wire is led out to power the heater.

[0016] In this embodiment, as shown in the figure, a sealing ring is provided on the inner wall of the through hole, and the sealing ring is used to seal with the electric wire of the heater to prevent foreign matter from entering.

[0017] In this embodiment, as shown in the figure, a baffle 23 is provided on the inner wall of the open groove, and the baffle divides the open groove into three chambers 211 of equal volume to separate multiple heaters.

[0018] In this embodiment, as shown in the figure, the top cover and the baffle are connected by screws, which makes assembly and disassembly more convenient. The top cover can be provided with a first mounting hole 52, the baffle can be provided with a second mounting hole 231 (threaded hole), and then both can be mounted by screws.

[0019] In this embodiment, as shown in the figure, the sealing ring is made of rubber.
