[0051] The motor 404 drives the first rotating shaft 403 to rotate, and then drives the first pulley 402 to rotate. When the first pulley 402 rotates, the transmission belt 401 and the second pulley 405 drive the second rotating shaft 601 to rotate. When the second rotating shaft 601 rotates, it drives the spiral blade 602 to rotate inside the feeding barrel 20, thereby transporting the mixed rubber roller raw materials.

[0053] While the motor 404 drives the first rotating shaft 403 to rotate and then drives the second rotating shaft 601 and the spiral blade 602 to rotate, the first rotating shaft 403 can also drive the incomplete gear 502 to rotate. During the rotation process, the incomplete gear 502 intermittently meshes with the outer gear ring 501, thereby driving the ring plate 302 to rotate intermittently. The intermittent rotation of the ring plate 302 drives the storage ring 30 to rotate intermittently around the feeding cylinder 20, so as to rotate the plurality of storage chambers 301 to the upper position in sequence, so that the plurality of storage chambers 301 are connected with the feeding port 201 in sequence. When a certain When the group storage chamber 301 is connected with the feed port 201, part of the rubber roller raw materials stored therein enter the mixing chamber 202 through the feed port 201. As part of the rubber roller raw materials in several storage chambers 301 enter the mixing chamber 202, the stirring component 70 stirs and mixes the various rubber roller raw materials in the mixing chamber 202. After the rubber roller raw materials in all the storage chambers 301 are partially entered into the mixing chamber 202, and after the stirring component 70 has finished stirring and mixing the various rubber roller raw materials, the rotating spiral blade 602 transports the rubber roller raw materials.

[0055] Initially, the plurality of first stirring rods 701 are away from each other on the second rotating shaft 601. As the motor 404 drives the second rotating shaft 601 and the spiral blade 602 to rotate, the second rotating shaft 601 drives the plurality of first stirring rods 701 to rotate inside the mixing chamber 202, and then stirs the rubber roller raw materials entering the mixing chamber 202, so that various rubber roller raw materials are mixed. After the rubber roller raw materials in the plurality of storage chambers 301 partially enter the mixing chamber 202, the plurality of first stirring rods 701 complete stirring and mixing the rubber roller raw materials. At this time, the third driving assembly 80 is used to drive the plurality of first stirring rods 701 to move along the second rotating shaft 601, so that the plurality of first stirring rods 701 away from each other are closed with each other and form a spiral plate connected to one end of the spiral blade 602. As the second rotating shaft 601 continues to rotate, the spiral plate is driven to rotate. When the spiral plate rotates, the mixed rubber roller raw materials are pushed to the spiral blade 602, and then the spiral blade 602 continues to push, thereby completing the feeding purpose of the rubber roller raw materials.

[0056] See also Figure 5 , Figure 6 as well as Figure 7 In one embodiment, a channel is provided inside the second rotating shaft 601, a spiral groove is provided on the side wall of the second rotating shaft 601, the rotation direction of the spiral groove is consistent with the rotation direction of the spiral blade 602, a plurality of slide plates 704 corresponding to the plurality of first stirring rods 701 are slidably provided inside the channel, the plurality of slide plates 704 are spaced apart along the length direction of the second rotating shaft 601, two adjacent groups of slide plates 704 are connected by a second elastic member 705, the second elastic member 705 is used to provide elastic support for the slide plates 704, one end of the plurality of stirring rods 701 extends from the spiral groove to the inside of the channel and is correspondingly connected to the plurality of slide plates 704, and the other end extends to the outside of the second rotating shaft 601, and the upper portion of the support plate 10 is also fixed A bracket plate 102 is provided, and the third driving component 80 includes a connecting plate 801, a resistance rod 802 and a sliding rod 803. One end of the sliding rod 803 extends from one end of the second rotating shaft 601 located outside the feeding barrel 20 to the inside of the channel and is telescopically matched with the second rotating shaft 601, and the other end extends to the outside of the second rotating shaft 601 and is fixedly connected to the connecting plate 802. One end of the resistance rod 802 is fixedly connected to the connecting plate 801, and the other end is abutted against the side wall of the bracket plate 102. The resistance rod 802, the connecting plate 802 and the sliding rod 803 form a Z-shaped structure. An arc-shaped protrusion 103 is fixedly provided on the side wall of the bracket plate 102, and the arc-shaped protrusion 103 is located on the rotation path of the resistance rod 802.

[0057] When the motor 404 drives the first rotating shaft 403 to rotate and then drives the second rotating shaft 601 and the spiral blade 602 to rotate, the second rotating shaft 601 can also drive the sliding rod 803 to rotate synchronously, and the sliding rod 803 drives the connecting plate 801 and the contact rod 802 to rotate. When the rubber roller materials in the plurality of storage chambers 301 partially enter the mixing chamber 202, the plurality of first stirring rods 701 complete the mixing of the rubber roller materials. At this time, the contact rod 802 acts on one end of the arc-shaped protrusion 103 and is pushed by the arc-shaped protrusion 103.

When the plurality of slide plates 704 approach each other, the plurality of first stirring rods 701 are driven to approach each other. The plurality of first stirring rods 701 slide along the inner part of the spiral groove and then stick to each other to form a spiral plate. The spiral plate is connected with one end of the spiral blade 602. The subsequent rotation of the second rotating shaft 601 drives the spiral plate to rotate. The spiral plate is used to push the mixed part of the rubber roller raw material toward the spiral blade 602. The spiral blade 602 pushes the mixed part of the rubber roller raw material out of the end of the feeding barrel 20, thereby achieving the purpose of feeding part of the rubber roller raw material.

[0059] When the resistance rod 802 acts on the arc-shaped protrusion 103 and pushes the sliding rod 803 to move toward the inside of the second rotating shaft 601, the first elastic member 604 is compressed by force; after the feeding of the current part of the rubber roller raw material is completed, the resistance rod 802 slides away from the other end of the arc-shaped protrusion 103. At this time, the first elastic member 604 pushes the connecting plate 801 and drives the sliding rod 803 to move toward the outside of the second rotating shaft 601. The resistance rod 802 abuts against the side wall of the bracket plate 103 again and slides along the side wall of the bracket plate 103. When the sliding rod 803 moves toward the outside of the second rotating shaft 601, the second elastic members 705 push the slide plates 704 to move the slide plates 704 away from each other, thereby driving the first stirring rods 701 away from each other, realizing the resetting of the first stirring rods 701, and then continuing to stir and mix the rubber roller raw materials that subsequently enter the mixing chamber 202.

[0066] When the second rotating shaft 601 rotates, the second stirring rods 702 can be driven to rotate synchronously. The second stirring rods 702 cooperate with the first stirring rods 701 to fully stir the rubber roller raw materials entering the mixing chamber 202, thereby improving the mixing effect of the rubber roller raw materials.

[0067] In one embodiment, a sealing plate is detachably provided in each group of the storage cavities 301.

When the storage ring 30 rotates intermittently, the plurality of storage chambers 301 can be driven to rotate to the top of the feed port 201 in sequence and then communicate with the feed port 201 in sequence, so that part of the rubber roller raw materials in the plurality of storage chambers 301 enters the mixing chamber 202 in sequence through the feed port 201. After the rubber roller raw materials in all the storage chambers 301 partially enter the mixing chamber 202, the stirring component 70 is used to stir the rubber roller raw materials. The various rubber roller raw materials inside the mixing chamber 202 are mixed with each other, and the mixed rubber roller raw materials are conveyed by the rotating feeding screw 60; as the storage ring 30 rotates intermittently again, part of the rubber roller raw materials inside the storage chambers 301 are again introduced into the mixing chamber 202 through the feed port 201 in sequence, the stirring component 70 stirs and mixes the rubber roller raw materials again, and the feeding screw 60 conveys the mixed rubber roller raw materials again.
