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.

[0027] Please see Figures 1-6 In this embodiment of the present invention, a novel material quantitative extrusion and shaping device includes an extrusion assembly 1 for quantitatively extruding material. The extrusion assembly 1 includes a material barrel 101, a sealing ring 102, a discharge port 103, a rotating shaft 106, and a threaded plate 107. Two sealing rings 102 are provided, and the two sealing rings 102 are symmetrically arranged and fixedly connected to the outer walls of both ends of the material barrel 101. The discharge port 103 is provided on the outer wall of one end of one sealing ring 102 and completely penetrates the outer wall of the other end of the sealing ring 102. The rotating shaft 106 is provided inside the material barrel 101, and both ends of the rotating shaft 106 completely penetrate the outer wall of the other end of the sealing ring 102. Two sealing rings 102 are inserted, and the outer wall of the rotating shaft 106 is rotatably connected to the inner wall of the sealing ring 102. The threaded plate 107 is sleeved on the outer wall of the rotating shaft 106 and fixedly connected to the outer wall of the rotating shaft 106. The outer wall of the threaded plate 107 is in contact with the inner wall of the material barrel 101. One end of the outer wall of the threaded plate 107 is in contact with one end of the outer wall of a sealing ring 102. The other end of the outer wall of the threaded plate 107 has a gap with one end of the outer wall of another sealing ring 102. A wall scraping assembly 2 is provided inside the material barrel 101. The wall scraping assembly 2 includes a scraper 201, a plate groove 202, a limiting post 203, and a limiting groove 204.

[0028] The scraper 201 is disposed inside the material barrel 101 and is slidably connected to the inner wall of the material barrel 101. The scraper 201 is sleeved on the outer wall of the rotating shaft 106 and is slidably connected to the outer wall of the rotating shaft 106. The scraper groove 202 is disposed on the outer wall of one end of the scraper 201 and extends through to the outer wall of the other end of the scraper 201. The inner wall of the scraper groove 202 is slidably connected to the outer wall of the threaded plate 107. The outer walls of both ends of the scraper groove 202 are respectively attached to the outer wall of the other end of the threaded plate 107 and the outer wall of one end of another sealing ring 102. Multiple limiting posts 203 are provided. Multiple limiting posts 203 are arranged in a circle and fixedly connected to one side of the outer wall of the scraper 201. Multiple limiting grooves 204 are provided. Multiple limiting grooves 204 are arranged in a circle on the outer wall of one end of the material barrel 101 and extend through to the outer wall of the other end of the material barrel 101. The inner wall of the limiting groove 204 is attached to the outer wall of the limiting post 203.

[0029] In this embodiment: When using the extrusion assembly 1, if the material inside the barrel 101 is too small to be extruded by the rotation of the threaded blade 107, it is only necessary to push the scraper 201 so that the scraper 201 slides toward the threaded blade 107. Then, when the threaded blade 107 rotates, the outer wall of one end of the threaded blade 107 slides into the blade groove 202. When the outer wall of the threaded blade 107 is in contact with the inner wall of the blade groove 202, the outer wall of the threaded blade 107 will press against the inner wall of the blade groove 202. When the scraper 201 slides, the outer walls of the multiple limiting posts 203 on the outer wall of the scraper 201 are in contact with the inner wall of the limiting groove 204, restricting the scraper 201 so that it cannot rotate, thereby allowing the material to be extruded through the threaded blade 107. The pressure of the wall against the inner wall of the slot 202 converts the rotation of the threaded blade 107 into the sliding of the scraper blade 201. When the scraper blade 201 slides, the inner wall of the scraper blade 201 is in contact with the outer wall of the rotating shaft 106, the outer wall of the scraper blade 201 is in contact with the inner wall of the material barrel 101, and the inner wall of the slot 202 is in contact with the outer wall of the threaded blade 107. This scrapes away the small amount of material remaining on the outer wall of the rotating shaft 106, the inner wall of the material barrel 101, and the outer wall of the threaded blade 107. When the scraper blade 201 gradually approaches a sealing ring 102, the material is squeezed to the discharge port 103 and discharged through the contact between the outer wall of the scraper blade 201 and the outer wall of the sealing ring 102. This solves the problem that when there is little material remaining, it cannot be squeezed out, which affects subsequent use.

Multiple fixing plates 105 are provided, and the multiple fixing plates 105 are arranged symmetrically and fixedly connected to one side of the outer wall of the material barrel 101. One end of the outer wall of the fixing plate 105 is flush with one end of the outer wall of the material barrel 101, and the outer wall of the fixing plate 105 is in contact with the outer wall of the limiting plate 104.

[0032] In this embodiment, it should be noted that bolts are required when fixing the sealing ring 102 to the material bucket 101.

[0033] By setting limit plates 104 and fixing plates 105, multiple limit plates 104 are arranged in a circle and fixedly connected to one side of the outer wall of the sealing ring 102, and multiple fixing plates 105 are arranged symmetrically and fixedly connected to one side of the outer wall of the material barrel 101. This allows the sealing ring 102 to be fixedly connected to the material barrel 101 simply by inserting a bolt from one end of the outer wall of the limit plate 104 until it fits against the outer wall of the fixing plate 105, and then threading the bolt to the fixing plate 105. When a major cleaning of the inside of the material barrel 101 is required, the sealing ring 102 can be removed simply by unscrewing the bolt, thus facilitating the cleaning of the inside of the material barrel 101.

The top of the inner wall of the inclined groove 205 does not fit with the inclined surface of the beveled post, so that when the scraper 201 slides to one end of the inner wall of the material barrel 101, the limiting post 203 can slide into the inclined groove 205, so that the outer wall of the scraper 201 can fit tightly with the outer wall of a sealing ring 102, thereby cleaning the inside of the material barrel 101.

[0043] Please refer to this carefully. Figure 2 , Figure 6 The wall scraping assembly 2 also includes a circular hole 206 and a cylinder 207;
