The installation of the existing charging barrel and hopper is difficult, and the accurate installation of the charging barrel and the hopper is completed because the feeding hole is a cylindrical hole or an inverted conical hole, so that the connection between the bottom end of the hopper and the feeding hole can cause a steering condition, and the pin fixation or flange plate fixation of the hole is completed by changing the position of the hopper; meanwhile, the novel charging barrel has no certain limiting capacity, and in the daily use process of the charging barrel, the barrel can shake, so that the charging barrel and the hopper are easily connected and loose or the feeding port is seriously abraded.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a wear-resisting barrel is used to extruder, through spacing and the spacing cooperation of axial of circumference for feed cylinder and hopper be convenient for install, can improve the installation stability, reduce the wearing and tearing probability of feed inlet.
The above technical purpose of the present invention can be achieved by the following technical solutions:
the utility model provides a wear-resisting barrel for extruder, includes the barrel body, sets up feed inlet and hopper on the barrel body, the feed inlet is the annular settlement and is used for supporting the hopper and rotates the action, the barrel body has seted up on feed inlet outer lane position with the communicating lower slide of feed inlet, the lower slide is seted up down from barrel body top and the symmetry is seted up on the feed inlet outer lane, certain length's spacing ring is seted up to the bottom circumference of lower slide, and spacing ring sets up with the axle center with the feed inlet, and the vertical section and the feed inlet that spacing ring was said communicate with each other completely, install the slider that successively gets into lower slide and spacing ring on the outer wall of barrel body, the top of barrel body is provided with the circumference locating part that is used for restricting hopper circumferential direction.
More preferably: the circumferential limiting part comprises an insertion groove formed in the outer wall of the hopper, an insertion piece and a flange plate, wherein the insertion piece and the flange plate are installed at the top end of the machine barrel body, the insertion groove is symmetrically formed in the outer wall of the hopper, the insertion piece is in an I-shaped design, and the end part of the insertion piece, far away from the insertion groove, is connected with the elastic reset piece.
To sum up, the utility model discloses the beneficial effect who contrasts in prior art does:
in the process of mounting the hopper, the sliding block is aligned with the top end opening of the lower slideway, so that the sliding block correspondingly enters the lower slideway and translates downwards along the lower slideway, the hopper can be conveniently mounted by the arrangement of the lower slideway, and the limiting action is completed in the first step;
when the sliding block reaches the bottommost end of the lower slideway, an installer can rotate the hopper to enable the sliding block to enter the limiting ring channel, and when the hopper cannot rotate, namely the inserting groove is opposite to the inserting sheet; spacing ring way can restrict the ability that the hopper reciprocated, and the hopper only has certain rotation ability this moment, and inserting groove and inserted sheet are gone up in the cooperation this moment, and the inserted sheet can restrict the hopper and rotate and have certain spacing ability that reciprocates, accomplishes the spacing and the spacing settlement of axial of hopper circumference for feed cylinder and hopper have simple to operate, the high advantage of installation stability in the installation, with this can reduce the wearing and tearing probability of feed inlet.

Detailed Description
The following provides a more detailed description of the present invention with reference to the accompanying drawings.
A wear-resistant cylinder for an extruder is shown in figures 1 and 2 and comprises a cylinder body 1, a feed inlet 2 and a hopper 3 which are arranged on the cylinder body 1, wherein a cylindrical cavity is arranged in a screw cylinder and is used for mounting and rotating a screw; the feed inlet 2 is annularly configured for supporting the hopper 3 to rotate, and in this embodiment, the feed inlet 2 is configured as an inverted conical hole, but not limited to a conical hole, and may also be configured as a cylindrical annular groove with an equivalent axial center.
The lower slide way 4 communicated with the feed inlet 2 is arranged on the outer ring of the feed inlet 2 of the machine barrel body 1, the lower slide way 4 is arranged from the top end of the machine barrel body 1 downwards, the bottom end of the lower slide way 4 does not penetrate through the wall thickness of the upper part of the machine barrel body 1, namely, the lower slide way is not communicated with the cylindrical cavity, in the actual design, the lower slide way 4 is arranged in a plurality of numbers so as to play a better installation alignment role and a better limiting role, in the embodiment, the number of the lower slide ways 4 is only two, and the lower slide ways are symmetrically arranged on the outer.
The bottom circumference of the lower slideway 4 is provided with a limit ring 5 with a certain length, the limit ring 5 is provided with a completely consistent height in the circumference, meanwhile, the limit ring 5 and the feed inlet 2 are coaxially arranged, and the vertical section of the limit ring 5 is completely communicated with the feed inlet 2.
Based on foretell glide slope 4 and spacing ring 5, install the slider 6 that successively gets into glide slope 4 and spacing ring 5 on the outer wall of feed cylinder body, the top of barrel body 1 is provided with the circumference locating part that is used for restricting 3 circumferential direction of hopper, the circumference locating part is including offering the inserting groove 7 on 3 outer walls of hopper, install the inserting piece 8 on 1 top of barrel body, and ring flange 9, inserting groove 7 is seted up to the symmetry on 3 outer walls of hopper, inserting piece 8 is the I shape design, keep away from 8 end connection elastic reset pieces of inserting piece of inserting groove 7.
The working process is as follows:
the sliding blocks 6 on the hopper 3 are aligned with the top end of the lower sliding block, so that each sliding block 6 enters the lower sliding channel 4, the first-step limiting is realized, and the hopper 3 can be conveniently installed; slider 6 enters into spacing ring way 5 after that, when slider 6 reachs 5 tail ends in spacing ring way, inserting groove 7 just is relative with insertion piece 8, spacing ring way 5 can be spacing to 3 axial of hopper, and the settlement of insertion piece 8 realizes that circumference is spacing and certain axial is spacing, as long as insertion piece 8 does not deviate from inserting groove 7, can make hopper 3 and the stable connection of feed cylinder body together, the cooperation has ring flange 9 simultaneously, lock hopper 3 and feed cylinder body, make feed cylinder and hopper 3 in the installation, and has simple to operate, the high advantage of installation stability, with this wearing and tearing probability that can reduce feed inlet 2.
