[0028] The following refers to Figure 1 and Figure 2 The description of the PVC extruding granulator according to the utility model embodiment.

[0029] As Figure 1 and Figure 2 shown, the PVC extruding granulator according to the utility model embodiment comprises a stirring cylinder 100, a straight feeding hopper 200, a vibration motor 300 and a granulator 400.

[0030] The stirring cylinder 100 is located at the top, the stirring cylinder 100 has a stirring feeding port 101 and a stirring discharge pipe 102, the raw material can enter the stirring cylinder 100 from the stirring feeding port 101 and be output from the stirring discharge pipe 102; the straight feeding hopper 200 is located at the bottom, the straight feeding hopper 200 has an inner cavity, the straight feeding hopper 200 comprises a straight cylinder portion 210 and an inverted cone portion 220 from top to bottom in sequence, the stirring discharge pipe 102 is in communication with the upper side of the straight cylinder portion 210, the upper side of the outer side wall of the straight cylinder portion 210 is provided with a supporting convex part 230, a vertical rod 240 is arranged between the supporting convex part 230 and the ground, the inverted cone portion 220 has a hopper outlet 221 at the lower side, the raw material can be output from the hopper outlet 221 after entering the inner cavity of the straight feeding hopper 200 from the stirring discharge pipe 102; the vibration motor 300 is located on the outer side wall of the inverted cone portion 220; the granulator feeding port 410 of the granulator 400 is in communication with the hopper outlet 221, and the raw material can enter the granulator 400 from the hopper outlet 221.

[0031] For example, as Figure 1 and Figure 2The stirring cylinder 100 is fixedly installed on the upper side. The stirring cylinder 100 has a stirring feeding port 101 and a stirring discharge pipe 102, so that the raw materials can be output from the stirring discharge pipe 102 after entering the stirring cylinder 100 from the stirring feeding port 101. The straight feeding hopper 200 is fixedly installed on the lower side. The straight feeding hopper 200 has an inner cavity. The straight feeding hopper 200 sequentially comprises a straight cylinder portion 210 and an inverted cone portion 220 from top to bottom, that is, the straight cylinder portion 210 and the inverted cone portion 220 form a complete hopper cavity structure of the straight feeding hopper 200, and the stirring discharge pipe 102 is in communication with the upper side of the straight cylinder portion 210. The upper side of the outer side wall of the straight cylinder portion 210 is provided with a supporting convex portion 230, and a vertical rod 240 is arranged between the supporting convex portion 230 and the ground. The inverted cone portion 220 has a hopper outlet 221 on the lower side, so that the raw materials can be output from the hopper outlet 221 after entering the inner cavity of the straight feeding hopper 200 from the stirring discharge pipe 102. The vibration motor 300 is arranged on the outer side wall of the inverted cone portion 220. The pelletizer feeding port 410 of the pelletizer 400 is in communication with the hopper outlet 221, and the raw materials can enter the pelletizer 400 from the hopper outlet 221.

[0032] In actual work, the raw materials are sent into the stirring cylinder 100 from the stirring feeding port 101 for stirring, and the powder-shaped raw materials are stirred into dough-shaped raw materials. The stirred raw materials enter the straight feeding hopper 200 through the stirring discharge pipe 102. Under the action of gravity, the raw materials fall into the inverted cone portion 220, and at the same time, the vibration motor 300 makes the straight feeding hopper 200 vibrate, so as to ensure that the dough-shaped raw materials can fall into the pelletizer 400 through the pelletizer feeding port 410 from the hopper outlet 221 for pelletizing work.

[0033] In the above process, the dough-shaped raw materials enter the straight feeding hopper 200 and sequentially pass through the straight cylinder portion 210 and the inverted cone portion 220, and then gather at the hopper outlet 221 on the lower side of the inverted cone portion 220. The design of the supporting convex portion 230 on the upper side of the outer side wall of the straight cylinder portion 210 cooperating with the vertical rod 240 to support the straight feeding hopper 200 can make the straight feeding hopper 200 vibrate with sufficient frequency and amplitude when the vibration motor 300 works, especially near the hopper outlet 221, so as to ensure that the raw materials can fall into the pelletizer 400 under the action of vibration and gravity. Moreover, the vibration does not affect the installation stability of the straight feeding hopper 200.

[0034] Due to the viscosity of the dough-like raw material, when the vibration motor 300 is not working, the raw material will adhere to the inner wall position of the hopper outlet 221 and will not directly fall down. When the vibration motor 300 is started, the raw material adhered to the inner wall position of the hopper outlet 221 will be vibrated under the action of gravity and fall into the granulator 400, which realizes the technical effect of "automatic feeding of the missing material". Moreover, the design of the vibration motor 300 cooperating with the straight feeding hopper 200 does not need to install a complex feeding device, such as a low-speed stirring cylinder, in the straight feeding hopper 200, which reduces the possibility of material jamming, and does not need to design an open structure near the hopper outlet 221 to handle the material jamming problem. The closed connection structure between the hopper outlet 221 and the granulator inlet 410 can reduce the problem of dust emission.

[0035] In some embodiments of the present application, the PVC extrusion granulator is installed in a factory building, wherein the stirring cylinder 100 is located in the upper layer area 710 of the factory building, the straight feeding hopper 200 and the granulator 400 are located in the lower layer area 720 of the factory building.

[0036] In some embodiments of the present application, referring to Figure 3 , the stirring shaft 110 with stirring blades 112 is arranged in the stirring cylinder 100, and the heating pipe 130 is arranged in the hollow shaft cavity 111 of the stirring shaft 110. When the stirring shaft 110 rotates, the stirring blades 112 rotate to stir the raw material. The heating pipe 130 can heat the raw material to improve the stirring effect, so that the raw material is more likely to form a dough-like effect, and the dough will not be prematurely bonded before entering the granulator.

[0037] In some specific embodiments of the present application, the stirring blades 112 are spiral blade structures.

[0038] In some specific embodiments of the present application, the stirring blades 112 are paddle blade structures.

[0039] In some specific embodiments of the present application, the heating pipe 130 adopts a resistance heating pipe structure.

[0040] In some embodiments of the utility model, the stirring cylinder 100 is provided with a stirring motor 120 and a heating controller 140, the stirring motor 120 is connected with the end of the stirring shaft 110, the stirring motor 120 can control the rotation of the stirring shaft 110, the heating controller 140 is fixedly connected with the end of the heating pipe 130, and the hollow shaft cavity 111 is filled with heat conducting oil. When the stirring motor 120 controls the rotation of the stirring shaft 110, the heating pipe 130 is relatively stationary, and the heat generated by the heating pipe 130 is conducted to the stirring shaft 110 and the stirring blade 112 through the heat conducting oil, so that heating work is carried out, and the hollow shaft cavity 111 between the heating pipe 130 and the stirring shaft 110 will not produce friction, so that the stirring work and the heating work are not affected.

[0041] In some embodiments of the utility model, the stirring discharge pipe 102 is an inclined pipeline structure, and the raw materials can enter the inner cavity of the straight feeding hopper 200 along the inclination angle of the stirring discharge pipe 102, so that the dough-like raw materials are more easily fallen into the straight feeding hopper 200.

[0042] In some embodiments of the utility model, the straight cylinder portion 210, the supporting convex part 230 and the vertical rod 240 are connected through welding, so that the straight cylinder portion 210, the supporting convex part 230 and the vertical rod 240 are connected stably, and especially the straight feeding hopper 200 is stable and reliable during the working process.

[0043] In some embodiments of the utility model, referring to Figure 2 The supporting convex part 230 is a triangular structure, the supporting convex part 230 has a triangular vertical surface 231, a triangular horizontal surface 232 and a triangular inclined surface 233, the triangular inclined surface 233 is located between the triangular vertical surface 231 and the triangular horizontal surface 232, the triangular vertical surface 231 is connected with the outer side wall of the straight cylinder portion 210, and the triangular horizontal surface 232 is connected with the vertical rod 240. The supporting convex part 230 with the above structure can provide better support for the vertical rod 240, especially when the vibration of the straight feeding hopper 200 is transmitted to the supporting convex part 230, the stress can be dispersed on the triangular inclined surface 233, so that the straight feeding hopper 200 is stable enough during the vibration process.

[0044] In some embodiments of the utility model, referring to Figure 4, a hinged plate 250 is arranged between the hopper outlet 221 and the granulator feed inlet 410, the hinged plate 250 has a hinge shaft 251, and the hinged plate 250 is controlled to rotate around the hinge shaft 251 by a switch motor 252. In this way, the hinged plate 250 can be controlled to open and close by controlling the rotation of the hinge shaft 251 by the switch motor 252. When the PVC extrusion granulator needs to be stopped for a long time, for example, 24 hours, the hinged plate 250 is rotated to close the hopper outlet 221, so that the raw materials cannot fall into the granulator. When the PVC extrusion granulator needs to work, it does not need to be stopped for a long time, and the hinged plate 250 is controlled to rotate to open the hopper outlet 221.

[0045] In some specific embodiments of the present application, the hinged plate 250 is installed in the screw feeder 500 between the hopper outlet 221 and the granulator feed inlet 410.

[0046] In some embodiments of the present application, the vibration motor 300 adopts a complex rotary vibration motor, which is not only simple in structure and easy to maintain, but also has better auxiliary material falling effect on the dough-like raw materials.

[0047] In some embodiments of the present application, a screw feeder 500 is arranged between the hopper outlet 221 and the granulator feed inlet 410, the screw feeder 500 comprises a feeding shell 510, the feeding shell 510 has a feeding inlet 511 and a feeding outlet 513, the feeding inlet 511 is communicated with the hopper outlet 221, the feeding outlet 513 is communicated with the granulator feed inlet 410, and a horizontal feeding screw 520 is arranged in the feeding shell 510. When the horizontal feeding screw 520 rotates, the raw materials can be concentrated at the position of the feeding outlet 513 along the threads of the screw, so that the raw materials can be more concentratedly fed into the feeder.

[0048] In some embodiments of the present application, a buffer step 512 is arranged on the inner wall of the feeding inlet 511, a buffer ring 600 is sleeved on the hopper outlet 221, and a buffer spring 610 is arranged between the buffer step 512 and the buffer ring 600, that is, the buffer spring 610 can provide a spring force to the buffer ring 600 on the hopper outlet 221 and the buffer step 512 in the feeding inlet 511 to provide a buffering effect. In this way, when the straight hopper 200 vibrates, the vibration can be reduced when it reaches the position of the buffer spring 610, that is, the vibration of the straight hopper 200 does not affect the work of the screw feeder 500 and the granulator 400.

[0049] In some specific embodiments of the present application, the buffer spring 610 is connected with the upper end surface of the buffer step 512 and the lower end surface of the buffer ring 600.

[0050] In some embodiments of the utility model, the buffer spring 610 is connected with the inner wall surface of the buffer step 512 and the outer side wall of the buffer ring 600.

[0051] In some embodiments of the utility model, the first gasket 620 is arranged between the hopper outlet 221 and the buffer ring 600, and the second gasket 630 is arranged between the outer side wall of the buffer ring 600 and the inner side wall of the feeding inlet 511.
