DETAILED DESCRIPTION

[0021] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figures 1 to 5 As shown, a feeding and conveying mechanism for injection molding of plastic building block toys includes a base 1, a conveying assembly 2 and a drying assembly 3. The conveying assembly 2 includes a conveying barrel 22 and a conveying shaft 21. The conveying shaft 21 is located inside the conveying barrel 22. The conveying shaft 21 is arranged in contact with the inner wall of the conveying barrel 22. A feed pipe 221 and a discharge port 222 are provided on the conveying barrel 22. The feed pipe 221 is connected to the conveying barrel 22. A plurality of flipping assemblies 4 are provided on the conveying shaft 21. The flipping assemblies 4 include a flipping plate 41 and a driving part 42 capable of driving the flipping plate 41 to flip.

[0023] During operation, the conveying component 2 and the drying component 3 are started, and the worker throws the material into the conveying barrel 22 from the feed pipe 221. The conveying shaft 21 rotates to convey the material inside the conveying barrel 22 to the discharge port 222. The conveying shaft 21 drives the driving part 42 in the flipping component 4 to work during the rotation, and the driving part 42 drives the flipping plate 41 to flip inside the conveying barrel 22. The flipping plate 41 drives the material inside the conveying barrel 22 to flip during the flipping process. The material is dried more fully during the flipping process. Through the setting of the flipping component 4, the flipping of the flipping plate 41 in the flipping component 4 avoids the accumulation of materials during the conveying process, thereby avoiding the accumulation of materials and causing insufficient drying.

[0024] Reference Figure 3 and Figure 5 As shown, the driving part 42 includes a roller 421 and a bearing 422. The roller 421 is located inside the conveying barrel 22 and on one side of the flip plate 41. A first fixing part 411 is provided at one end of the roller 421 close to the flip plate 41. The first fixing part 411 is connected to the flip plate 41. The working end of the roller 421 abuts against the inside of the conveying barrel 22. The bearing 422 is provided at one end of the roller 421 away from the flip plate 41. The bearing 422 is rotatably connected to the roller 421. A second fixing part 43 is provided at one end of the bearing 422 away from the roller 421. The second fixing part 43 is connected to the conveying shaft 21.

[0025] During operation, the conveying shaft 21 rotates through the second fixed part 43 to drive the roller 421 to rotate around the axis of the conveying shaft 21. The roller 421 rubs against the inner wall of the conveying barrel 22 while rotating, so that the roller 421 rotates around the axis of the conveying shaft 21 while rotating on its own. The rotation of the roller 421 drives the flip plate 41 to rotate through the first fixed part 411. The rotation of the flip plate 41 can drive the material inside the conveying barrel 22 to flip.

[0026] Reference Figure 3 and Figure 5 As shown, the first fixing portion 411 includes a plug-in plate 412, a nut 415 and a bolt 414. The plug-in plate 412 is arranged at one end of the roller 421 close to the flip plate 41. The flip plate 41 is provided with a plug-in groove 413 which is plugged into and matched with the plug-in plate 412. The nut 415 is located on the flip plate 41, and the bolt 414 is located on the side of the flip plate 41 away from the nut 415. The working end of the bolt 414 passes through the plug-in plate 412, the flip plate 41 and the nut 415 for threaded connection.

[0027] When the flip plate 41 needs to be installed or replaced, the nut 415 is screwed off, the bolt 414 is pulled out, and the flip plate 41 is removed from the plug-in plate 412 .

[0028] Reference Figure 3 and Figure 5 As shown, the second fixing portion 43 includes an elastic key 431 and a sleeve 432. There are multiple elastic keys 431, and the multiple elastic keys 431 are arranged on the conveying shaft 21. The sleeve 432 is located at the end of the bearing 422 away from the roller 421. The sleeve 432 is connected to the bearing 422. The end of the sleeve 432 away from the bearing 422 is provided with a snap-in groove 4321 that cooperates with the elastic key 431.

[0029] When the driving part 42 needs to be replaced, the flip plate 41 is first removed. After the flip plate 41 is removed, the sleeve 432 is pulled off the elastic key 431 by pinching the elastic key 431 .

[0030] Reference Figure 3 As shown, a protective cover 5 is provided on the upper cover of the driving part 42 , one end of the protective cover 5 is connected to the sleeve 432 , and the other end of the protective cover 5 is rotatably connected to the plug board 412 , and a gap is left between the bottom of the protective cover 5 and the conveying barrel 22 .

[0031] When the conveying shaft 21 rotates, the protective cover 5 can separate the material from the roller 421 to prevent the material from getting stuck on the roller 421 and making it unable to rotate.

[0032] Reference Figure 1 As shown, a plurality of opening and closing plates 6 are provided on the conveying barrel 22 , and the opening and closing plates 6 correspond to the flipping assemblies 4 one by one, and a handle 61 is provided on the opening and closing plates 6 .

[0033] When one of the multiple flip assemblies 4 needs to be repaired or replaced, the corresponding opening and closing plate 6 can be opened through the handle 61 for repair or replacement.

[0034] Reference Figure 1 As shown, a temperature detector 7 is provided on the outer wall of the delivery barrel 22 .

[0035] The temperature detector 7 can detect the temperature inside the conveying barrel 22 in real time and feed it back to the external controller. The controller controls the start-up of the drying component 3 to keep the temperature inside the conveying barrel 22 within a preset range.

[0036] Reference Figure 5 As shown, the working end of the roller 421 is provided with anti-slip grooves 4211.

[0037] The provision of the anti-slip groove 4211 can increase the friction between the roller 421 and the conveying barrel 22, so that the roller 421 can rotate better.

[0038] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
