Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment:

an extrusion device with a sealing structure for PVC pipe production comprises a device body 100, the device body 100 comprises an extrusion device main body 110, one side of the extrusion device main body 110 is fixedly provided with an injection head 111, the top end of the injection head 111 is fixedly provided with a feed port 112, the top end of the feed port 112 is fixedly provided with a sealing cover 127, a rubber ring at the bottom end of the sealing cover 127 is attached to the inner side of the feed port 112, a sleeve ring 113 is movably arranged between the front inner wall and the rear inner wall of the feed port 112 through a bearing, the outer side of the sleeve ring 113 is uniformly and fixedly provided with a plurality of material bearing plates 114, one side of the inner wall of the feed port 112 is fixedly provided with a first fixing frame 115, one side of the first fixing frame 115 is provided with a chute 116, the top end of the inner wall of the chute 116 is fixedly provided with a compression spring 117, the bottom end of the compression spring 117 is fixedly provided with a slide rod 118, when a material enters the feed port 112, the material falls onto the material bearing plates 114, and apply clockwise downward force to the material-bearing plate 114, the material-bearing plate 114 of one side is propped against the bottom end of the slide rod 118 at this moment, as the force applied to the material-bearing plate 114 by the material is larger, the force applied to the slide rod 118 by the material-bearing plate 114 propped against the slide rod 118 is larger, until the material-bearing plate 114 pushes the slide rod 118 to move upwards, and then the material-bearing plate 114 bearing the material is inclined, so that the raw material falls into the inside of the injection head 111, and through this way, the raw material falling into the injection head 111 is slowed down, and the situation that the raw material inside the injection head 111 is increased when the blanking is continued, so that the internal pressure is too large, and the use of the device is influenced is generated.

Further, a guide plate 126 is fixedly mounted on one side of the inner wall of the feeding hole 112, and the guide plate 126 is inclined, so that raw materials entering the feeding hole 112 can be guided, the situation that the raw materials enter the left material bearing plate 114 is avoided, and the working stability of the device is improved.

Furthermore, a pull rope 120 is fixedly installed at the top end of the sliding rod 118, a through groove 119 is formed in one side of the inner wall of the feed port 112, one end of the pull rope 120, which is far away from the sliding rod 118, penetrates through the through groove 119 and extends to the outer side of the feed port 112, a fixing ball 121 is fixedly installed at one end of the pull rope 120, which is far away from the sliding rod 118, when a small amount of raw materials need to be added, the fixing ball 121 can be held to pull downwards, at this time, the pull rope 120 drives the sliding rod 118 to move upwards, and then the sliding rod 118 does not block the material bearing plate 114 any more, at this time, the material bearing plate 114 does not block the raw materials falling into the feed port 112 any more, and the filling is facilitated.

Further, one side fixed mounting of feed inlet 112 has fixed plate 122, the vertical recess 123 of having seted up that runs through in top of fixed plate 122, after the staff pulls fixed ball 121 to a certain position downwards, can transversely block the inside of recess 123 with stay cord 120, can stop the application of force to fixed ball 121 this moment, because the elasticity that compression spring 117 resets, fixed ball 121 and fixed plate 122 bottom are laminated mutually this moment, fix the position of litter 118, need not the staff and continue the application of force, the use flow of device has been simplified.

Furthermore, a second fixing frame 124 is fixedly mounted at the top end of the first fixing frame 115, a guide wheel 125 is movably mounted at one end, away from the first fixing frame 115, of the second fixing frame 124 through a rotating shaft, the outer side of the guide wheel 125 is attached to the pull rope 120, when the pull rope 120 moves, one side of the pull rope 120 is attached to the outer side of the guide wheel 125, the tension of the pull rope 120 can be maintained in this way, and the situation of abrasion caused by contact between the pull rope 120 and the groove edge of the through groove 119 is reduced.

Furthermore, the top end of the sealing cover 127 is fixedly provided with a connecting rope 128, one end of the connecting rope 128, which is far away from the sealing cover 127, is fixedly connected with the feed inlet 112, when the sealing cover 127 is pulled out and the feed inlet 112 is no longer limited, the connecting rope 128 limits the sealing cover 127, and the situation that the sealing cover 127 is separated from the feed inlet 112 is avoided.

The working principle is as follows: when the material receiving plate 114 is pushed to rotate clockwise and clockwise, the sleeve ring 113 rotates clockwise, after the sleeve ring 113 rotates clockwise and rotates a certain position, the material receiving plate 114 on one side abuts against the slide rod 118, the material receiving plate 114 abutting against the slide rod 118 exerts an upward force on the slide rod 118 with the increase of the material, the slide rod 118 moves upward and drives the compression spring 117 to compress and deform, so that the material receiving plate 114 contacting with the slide rod 118 passes through, the material receiving plate 114 bearing the material inclines downwards in the material receiving port 112, and the material on the material receiving plate 114 slides to the inside of the material receiving port 112, at this point, hot melt extrusion of the feedstock begins.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
