[0043] In this embodiment, the reset portion includes an electromagnet 129 and a tension spring 130. A plurality of electromagnets 129 are provided, and each electromagnet 129 is correspondingly arranged in a first groove 125. A ferromagnetic material is provided on the end surface of the rotating shaft 107 which is slidably arranged in the first groove 125. The ferromagnetic material and the electromagnet 129 are arranged along the axial direction of the rotating shaft 107. A plurality of second grooves 131 are provided on the bottom plate 118 of the rotating shaft 107. The number of the second grooves 131 is consistent with the number of the first grooves 125. One end of each rotating shaft 107 close to the bottom plate 118 is slidably arranged in a second groove 131. A plurality of tension springs 130 are provided, and each tension spring 130 is arranged in a second groove 131. The two ends of the tension spring 130 are respectively connected to the bottom plate 118 and the rotating shaft 107. The magnetic force of the electromagnet 129 is greater than that of the tension spring 1 30, the pulling force of the tension spring 130 is greater than the friction force between the rotating shaft 107 and the first groove 125. When the outer cylinder 101 pulls the rotating shaft 107 to slide in the first groove 125 through the bottom plate 118 and the tension spring 130, the tension spring 130 is in a tightened state. The pulling force at this time can pull the rotating shaft 107 to slide in the first groove 125. If the electromagnet 129 is energized, the magnetic force generated by the electromagnet 129 can overcome the pulling force of the tension spring 130 at this time to attract the rotating shaft 107 to move to a position close to the electromagnet 129. The rotating shaft 107 slides in the first groove 125 and rotates in the opposite direction. The torsion spring is reversely charged through the sliding sleeve 128. The partition 108 located between the two adjacent first rings 104 rotates to between the first ring 104 and the second ring 105 under the action of the torsion spring, so as to facilitate the resetting of the outer cylinder 101.
[0044] In this embodiment, each partition 108 is provided with an air hole 132, and in the radial direction of the rotating shaft 107, the air hole 132 is located on one side of the axis of the rotating shaft 107, and when the material in the first cavity 103 is not exchanged with the material in the second cavity 121, the material in the first cavity 103 cannot pass through the air hole 132, and when the material in the first cavity 103 is exchanged with the material in the second cavity 121, the material in the first cavity 103 can pass through the air hole 132, and when the material is added to the first cavity 103 through the two feed ports 109, the material in the first cavity 103 will not pass through the air hole 132 only due to its own gravity, and the materials in the two cavities will not be mixed, and when the spiral blade 106 rotates to transport the material in the second cavity 121 to the first cavity 103, the material in the first cavity 103 increases, the force of the material on the partition 108 increases, and the material can pass through the air hole 132.
[0045] In another embodiment, the two surfaces of each partition 108 away from the corresponding rotating shaft 107 are at different distances from the rotating shaft 107. After the material in the second cavity 121 enters the first cavity 103, the partition 108 is subjected to forces of different magnitudes on both sides of the rotating shaft 107. Therefore, the partition 108 can deflect around the rotating shaft 107, thereby mixing the materials in the two cavities in the first cavity 103.
[0046] In this embodiment, each first ring 104 and each second ring 105 is respectively provided with a through groove 133 that penetrates the end faces of the first ring 104 and the second ring 105, and each through groove 133 penetrates the corresponding first ring 104 and the second ring 105 along the radial direction of the inner cylinder 102. When discharging materials, the two side surfaces of each partition 108 away from the corresponding rotating shaft 107 are slidingly connected to the outer cylinder 101 and the inner cylinder 102 respectively. In the process of the rotating shaft 107 driving the partition 108 to rotate, the partition 108 gathers the materials on the inner wall of the outer cylinder 101 and the outer wall of the inner cylinder 102 together and moves downward from the corresponding through groove 133, thereby improving the cleaning effect of the first cavity 103.
[0047] The working principle and working method of a bicycle saddle polyester foam plastic foaming molding device provided in this embodiment are as follows:
[0048] The stirring mechanism has a first state, a second state and a third state. In the first state, the first ring 104 and the second ring 105 are alternately distributed along a first direction, the first direction is the extension direction of the axis of the inner cylinder 102, the spiral blade 106 does not rotate, and the two baffles 108 located on the same plane in the two adjacent groups of reversing components contact each other, and the materials in the two cavities in the first cavity 103 will not be mixed; in the second state, the first ring 104 and the second ring 105 are alternately distributed along the first direction, the spiral blade 106 rotates, and one side of each baffle 108 and the first ring 104 or the second ring 105 closest to it are in contact with each other. In the third state, each first ring 104 and a second ring 105 are located on the same plane, and the two sides of one partition 108 of the two adjacent partitions 108 in the same group of reversing components are respectively in contact with the first ring 104 and the second ring 105, and the two sides of the other partition 108 are respectively in contact with the outer cylinder 101 and the inner cylinder 102, and the end of the inner cylinder 102 away from the fixed frame 100 is completely separated from the annular opening 119, and the materials in the first cavity 103 and the second cavity 121 are discharged from the discharge port 115 through the annular opening 119.
[0049] First, two different materials are added to the two cavities of the first cavity 103 through the two discharge ports 115, and one of the materials enters the second cavity 121 through the first through hole 110. At this time, the stirring mechanism is in the first state, and the two materials entering the first cavity 103 will not be mixed; then the motor 134 is started, and the motor 134 drives the spiral blade 106 to rotate. The spiral blade 106 rotates to squeeze the material in the second cavity 121 through the second through hole 111 into a cavity in the first cavity 103, and the material in the cavity increases, the material begins to flow, and the excess The material passes through the first through hole 110 and returns to the second cavity 121 again. When the flowing material passes through the second ring 105, due to the small distance between the second ring 105 and the corresponding partition 108, the liquid will impact the partition 108, pushing the partition 108 to rotate. The rotated partition 108 connects the two cavities in the first cavity 103, and the two materials in the two cavities can be mixed. Under the guidance of the partition 108, the flowing material can rotate along the circumference of the inner tube 102, further promoting the mixing effect of the material. At this time, the stirring mechanism is in the second state.
[0050] When the material mixing is completed and needs to be discharged, the motor 134 stops rotating and then starts to reverse. The reversed spiral blade 106 transports the material in the second cavity 121 into the first cavity 103 through the first through hole 110. The material in the first cavity 103 will not enter the second cavity 121 due to the action of the one-way valve in the second through hole 111. As the material in the first cavity 103 increases, the outer cylinder 101 slides relative to the inner cylinder 102 along the axial direction of the inner cylinder 102, and the volume of the first cavity 103 increases. When the outer cylinder 101 drives the first ring 104 to move until each first ring 104 can be on the same plane with one of the corresponding second rings 105, the inner cylinder 102 slides out of the annular opening 119, and the material in the first cavity 103 can be discharged from the discharge port 115 through the annular opening 119. At this time, the stirring mechanism is in the third state.
[0051] During the movement of the outer cylinder 101, the outer cylinder 101 drives the bottom plate 118 to move together, and the bottom plate 118 pulls the rotating shaft 107 to move through the tension spring 130. After the rotating shaft 107 moves in the first groove 125, it rotates under the action of the spiral groove 126. The rotation of the rotating shaft 107 drives the sliding sleeve 128 to rotate, and the rotation of the sliding sleeve 128 drives the torsion spring to store force. When the positions of the first ring 104 and the second ring 105 correspond, the torsion spring that has stored force begins to release energy, and each partition 108 rotates under the action of the torsion spring and aligns with the inner cylinder 102 wall and the outer cylinder 102 wall at the corresponding position. 1 wall contact or the first ring 104 and the second ring 105 are in contact; the spiral blade 106 drives the rotating frame 127 to rotate through the transmission rod 123, the rotating frame 127 drives the bottom plate 118 to rotate through the ratchet mechanism, the bottom plate 118 drives all the partitions 108 to rotate through multiple rotating shafts 107, the partitions 108 scrape the materials on the contacted surface, under the action of the partitions 108, the materials attached to the inner wall in the first cavity 103 are collected, and then approach the annular opening 119 through the through groove 133, and finally discharged through the discharge port 115.
[0052] When the first cavity 103 is connected to the annular opening 119, the first gas port 116 is connected to the second gas port 117, and the second gas port 117 is connected to the first cavity 103. When all the materials in the second cavity 121 enter the first cavity 103, inert gas is introduced from the first gas port 116, and the inert gas pressurizes the materials in the first cavity 103, prompting the materials in the first cavity 103 to be discharged.
[0053] When the material in the first cavity 103 is discharged, the electromagnet 129 is started, and the electromagnet 129 is energized to attract the rotating shaft 107. The rotating shaft 107 pulls the tension spring 130 to extend, and the rotating shaft 107 rotates in the first groove 125 and approaches the electromagnet 129. When the rotating shaft 107 rotates, it drives the sleeve 128 to rotate in the opposite direction, and the sleeve 128 drives the torsion spring to store force in the opposite direction. The partition 108 can rotate in the opposite direction and return to between the first ring 104 and the second ring 105. At this time, the outer cylinder 101 is close to the fixed frame 100 under the action of the tension spring 130, and the stirring mechanism returns to the first state.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
