[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example:

[0021] Please see Figure 1 As shown:

[0022] Thermoplastic extrusion molding equipment includes a hopper 1.

[0023] In this implementation plan: In order to solve the technical problems existing in the prior art, such as the "existing injection molding extrusion equipment may experience blockage during the material conveying process, which makes the inspection and maintenance process more complicated and the operation more complicated, requiring the disassembly and assembly of relevant parts to complete the work", in combination with the use, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve the above problems, a closed groove 2 and a rotating shaft 3 are added on the basis.

[0024] Furthermore:

[0025] like Figure 1 - Figure 4 As shown:

[0026] Based on the above: A closed groove 2 is provided on one side of the hopper 1, and one side surface of the hopper 1 is rotatably connected to one end of the rotating shaft 3. The other end of the rotating shaft 3 is fixedly connected to the surface of the feed inlet 4. A sealing plate 5 that is slidably connected to the closed groove 2 is also fixedly installed on one side of the rotating shaft 3. A feeding pipe 6 that is slidably connected to the hopper 1 and the feed inlet 4 is also fixedly installed on the surface of the rotating shaft 3. An A positioning ring 7 and a B positioning ring 11 are fixedly installed on the surface of the feeding pipe 6. The surface of the A positioning ring 7 is fixedly connected to one end of the A spring 8, and the surface of the B positioning ring 11 is fixedly connected to one end of the B spring 12. The other ends of the A spring 8 and the B spring 12 are respectively fixedly installed on the surfaces of the A collar 9 and the B collar 13 that are slidably connected to the feeding pipe 6. The end of the A collar 9 away from the feeding pipe 6 is fitted and connected to the A limiting ring 10 fixedly installed on the surface of the hopper 1. The B collar 13 is fitted and connected to the B limiting ring 14 fixedly installed on the surface of the feed inlet 4.

[0027] In this implementation scheme: When the device is performing normal feeding and extrusion operations, the material is transported through the hopper 1 and the feeding pipe 6 to the location of the inlet 4, and then conveyed to the heating section through the inlet 4. At this time, the sealing plate 5 is on the outside of the hopper 1. When a blockage or other malfunction occurs during the material conveying process, the A collar 9 and B collar 13 on the surface of the feeding pipe 6 can slide. At this time, they will gradually move away from the location of the hopper 1 and the inlet 4 and compress the A spring 8 and B spring 12, while the A positioning ring 7 and B positioning ring 12 will be compressed. Ring 11 will bear the load of spring A 8 and spring B 12. As collar A 9, collar B 13, limit ring A 10, and limit ring B 14 gradually move away, the feeding pipe 6 will no longer be restricted in position. At this time, the feeding pipe 6 can be rotated along the rotating shaft 3, and the sealing plate 5 will gradually slide into the closed groove 2 opened on the surface of the hopper 1 under the action of the rotating shaft 3 and block the outlet below the hopper 1 to prevent the material in the hopper 1 from continuing to be conveyed. At this time, the inside of the feeding pipe 6 or the feed inlet 4 can be inspected or maintained.

[0028] Furthermore:

[0029] In an optional embodiment, the sealing groove 2 is formed on one side of the hopper 1, and the diameter of the sealing groove 2 matches the diameter of the sealing plate 5, and the diameter of the sealing plate 5 is smaller than the outer diameter of the hopper 1 and larger than the inner diameter of the hopper 1.

[0030] In this embodiment, the closed groove 2 on the surface of the silo 1 can slide effectively with the sealing plate 5, thereby blocking the material above the silo 1 when the sealing plate 5 slides into the silo 1 and the interior of the closed groove 2, making the maintenance work below the silo 1 more convenient.

[0031] Furthermore:

[0032] In an optional embodiment, the feed inlet 4, the hopper 1, and the feed pipe 6 are on the same straight line, and the end of the hopper 1 has the same diameter as the feed inlet 4 and the feed pipe 6.

[0033] In this embodiment, the material hopper 1, the feed inlet 4, and the feeding pipe 6, which are arranged on the same straight line, can ensure that the material can pass smoothly through the feeding pipe 6 and reach the position of the feed inlet 4 when the material hopper 1 is feeding. This provides an effective path for the feeding operation.

[0034] Furthermore:

[0035] In an optional embodiment, positioning ring 7, spring 8, collar 9, positioning ring 11, spring 12, and collar 13 are symmetrically arranged on the surface of the feed tube 6.

[0036] In this embodiment, the symmetrical arrangement on both sides of the feeding pipe 6 can provide stable connection points for the feeding pipe 6, enabling the feeding operation of the feeding pipe 6 to continue continuously and with high flexibility.

[0037] Furthermore:

[0038] In an optional embodiment, the inner diameters of collar A 9 and collar B 13 are the same as the outer diameter of the feed tube 6.

[0039] In this embodiment, the sealing plate 5 and the feeding pipe 6 and the B collar 13 can achieve stable sliding operation, thereby fixing the feeding pipe 6 when the A collar 9 and the B collar 13 are displaced.

[0040] Furthermore:

[0041] In an optional embodiment, the A limiting ring 10 and the B limiting ring 14 are annular in shape.

[0042] In this embodiment, the A limiting ring 10 and B limiting ring 14, which are arranged in a ring shape, can block the positions of the A collar 9 and B collar 13, so that they can stably connect the feeding pipe 6, the hopper 1 and the feed port 4.

[0043] The working principle and usage process of this utility model are as follows: When the device is performing normal feeding and extrusion operations, the material is transported through the hopper 1 and the feeding pipe 6 to the location of the inlet 4, and then conveyed to the heating section through the inlet 4. At this time, the sealing plate 5 is on the outside of the hopper 1. When a blockage or other malfunction occurs in the material conveying process, the A collar 9 and B collar 13 on the surface of the feeding pipe 6 can slide. At this time, the two will gradually move away from the location of the hopper 1 and the inlet 4 and compress the A spring 8 and B spring 12, while the A positioning ring 7... The B positioning ring 11 will bear the load of the A spring 8 and the B spring 12. As the A collar 9, the B collar 13, the A limiting ring 10, and the B limiting ring 14 gradually move away, the feeding pipe 6 will no longer be restricted in position. At this time, the feeding pipe 6 can be rotated along the rotating shaft 3, and the sealing plate 5 will gradually slide into the closed groove 2 opened on the surface of the hopper 1 under the action of the rotating shaft 3 and seal the outlet below the hopper 1 to prevent the material in the hopper 1 from continuing to be conveyed. At this time, the inside of the feeding pipe 6 or the feed inlet 4 can be inspected or maintained.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
