Description

Technical Field

[0001] This invention relates to the field of rubber recycling and preparation technology, and in particular to production equipment and processes for modified rubber shoe soles based on recycled waste rubber materials. Background Technology

[0002] In existing technologies, waste rubber products are recycled and processed into granular raw materials suitable for modified rubber shoe soles. Waste rubber products generally contain non-rubber skeleton materials such as fibers and metals, and given the wide variety of rubber products, pre-processing is necessary before pulverizing the waste rubber. This includes sorting, removal, cutting, and washing. Waste rubber, especially tires and rubber shoes, often contains a lot of mud and sand due to prolonged contact with the ground; therefore, it should first be cleaned using a rotary drum washer to ensure the quality of the rubber powder.

[0003] Current technologies for processing waste rubber often involve multiple machines, requiring significant investment in space and manpower. Furthermore, the processing of waste rubber involves raw materials of varying sizes and shapes, necessitating the separation of impurities and smaller pieces to prevent affecting the quality of the rubber powder. Rubber powder production typically employs a cryogenic method, usually requiring the use of liquid nitrogen to treat the recycled rubber at low temperatures before mechanically pulverizing it to obtain the powder. However, this method demands large quantities of liquid nitrogen, resulting in high production costs.

[0004] Therefore, this application provides production equipment and process for modified rubber shoe soles based on recycled waste rubber materials to meet the needs. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The technical problem to be solved by the present invention is to provide a production equipment and process for modified rubber shoe soles based on recycled waste rubber materials, so as to solve the problems of high raw material cost of existing low temperature crushing and the inability to integrate the crushing and processing of waste rubber.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] The equipment and process for producing modified rubber shoe soles based on recycled waste rubber materials include a support frame, a first outer shell fixedly installed on the top of the support frame, a first dust cover fixedly installed on the top of the first outer shell, a second dust cover fixedly installed on one side of the first outer shell, a mixing hopper fixedly installed at the bottom of the second dust cover, a screening mechanism inside the first dust cover, a grinding mechanism inside the second dust cover, and a mixing and pressing mechanism inside the mixing hopper.

[0010] The screening mechanism includes a first limiting ring, a separation tube, a centrifugal chamber, a paddle, and a hopper. The first limiting ring is fixedly installed at the bottom of a first dust cover. A separation tube is fixedly installed on one side of the first limiting ring. A centrifugal chamber is fixedly installed on one side of the separation tube. A paddle is movably installed inside the centrifugal chamber. A hopper is fixedly installed at the bottom of the centrifugal chamber.

[0011] As a preferred embodiment, the screening mechanism further includes a first rotating shaft, a second rotating shaft, and a servo motor. The servo motor is fixedly mounted on the top of the second dust cover, and the top of the servo motor is keyed to the second rotating shaft, while the top of the second rotating shaft is keyed to the first rotating shaft.

[0012] As a preferred embodiment, the screening mechanism is located at the top of the second dust cover, the grinding mechanism is located at the bottom of the screening mechanism, and the mixing and pressing mechanism is located at the bottom of the grinding mechanism.

[0013] As a preferred embodiment, the mixing mechanism is located at the bottom of the support frame and at the bottom of the first housing.

[0014] As a preferred embodiment, the grinding mechanism includes a positioning ring, a second housing, a guide bucket, a threaded sleeve, and a bearing ring. The positioning ring is fixedly installed inside the second dust cover. The second housing is movably installed at the bottom of the positioning ring. The threaded sleeve is fixedly installed at the bottom of the second housing. The guide bucket is provided at the bottom of the threaded sleeve. The bearing ring is fixedly installed at the bottom of the positioning ring.

[0015] As a preferred embodiment, the grinding mechanism further includes a second limiting ring, a positioning ring, a turbine, and a conical abrasive column. The second limiting ring is fixedly installed at the bottom of the positioning ring, the positioning ring is fixedly installed on one side of the second limiting ring, the turbine is movably installed on one side of the positioning ring, and the conical abrasive column is provided on one side of the turbine.

[0016] As a preferred embodiment, the mixing mechanism includes a hydraulic cylinder, a base, a hydraulic column, a pressure-bearing block, a connecting block, a telescopic rod, a gripper, a positioning rod, and an upper mold. The hydraulic cylinder is fixedly installed at the bottom of the servo motor. The base is fixedly installed at the bottom of the hydraulic cylinder. The hydraulic column is fixedly installed at the bottom of the base. The pressure-bearing block is fixedly installed at the bottom of the hydraulic column. The connecting block is fixedly installed at the bottom of the connecting block. The telescopic rod is hinged to the bottom of the telescopic rod. The gripper is movably connected to one side of the gripper. The upper mold is fixedly installed on one side of the positioning rod.

[0017] As a preferred embodiment, the conical frosted column is fixedly sleeved on one side of the second rotating shaft, and the turbine is movably mounted on one side of the second limiting ring.

[0018] As a preferred embodiment, a gripper is movably connected to one side of the upper mold, and the telescopic rod is located on one side of the hydraulic column.

[0019] As a preferred solution, in step one: the recycled rubber is poured into the centrifuge chamber through the first dust cover, and the second shaft is driven to rotate by starting the servo motor, which in turn drives the first shaft to drive the blades to rotate, causing the rubber material to rotate inside the centrifuge chamber. Small pieces of rubber material are separated from the first limiting ring through the separation tube, while large pieces of rubber material are driven by the blades and fall into the discharge hopper through the gap between the first limiting ring and the centrifuge chamber.

[0020] Step 2: Large pieces of rubber raw material enter the second outer shell through the hopper and positioning ring. The second rotating shaft drives the conical grinding column and the second outer shell to rotate. The second outer shell further drives the threaded sleeve to rotate at the bottom of the bearing ring, thereby driving the turbine meshing on one side of the threaded sleeve to rotate. Together with the conical grinding column, the large pieces of raw material are stuck between the two and ground into granules.

[0021] Step 3: After the granular raw material falls onto the surface of the guide hopper, it enters the bottom of the mixing bin. By starting the hydraulic cylinder, the hydraulic column extends and presses down, which drives the upper mold to squeeze the raw material that has fallen to the bottom of the mixing bin for preliminary processing.

[0022] Step 4: Add auxiliary materials between the first limiting ring and the centrifugal chamber. The auxiliary materials enter the bottom of the mixing chamber through the feeding hopper, the second outer shell, the guide hopper and the conical grinding column to mix with the raw materials.

[0023] Step 5: After the raw materials and auxiliary materials are mixed, the hydraulic cylinder is started to drive the hydraulic column to move in a linear reciprocating motion. When the hydraulic column extends, it drives the telescopic rod to extend, further rotating and opening the gripper around the positioning rod. When the upper mold reaches the bottom of the mixing chamber, the raw materials and auxiliary materials are squeezed.

[0024] Step Six: When the hydraulic column retracts, it drives the positioning rod to retract. When the hydraulic column retracts to the same length as the telescopic rod and then retracts further, the gripper rotates around the positioning rod and fits against the mold, while simultaneously gathering the mixture at the bottom of the mixing bin to the bottom of the mold.

[0025] Step 7: By repeatedly extending and contracting the hydraulic column, the upper mold is used to extrude the mixture until the rubber raw material and auxiliary materials have fully reacted and the rubber modification is completed. (III) Beneficial Effects

[0026] Compared with the prior art, the present invention provides a sampling and filling device for highway engineering, which has the following beneficial effects:

[0027] 1. In the above scheme, by setting up paddles, the servo motor drives the first rotating shaft to rotate, which in turn drives the paddles to rotate and at the same time drives large pieces of raw material to leave the centrifuge chamber and enter the space between the first limiting ring and the centrifuge chamber to complete the screening; while the paddles are rotating, impurities and small pieces of raw material that do not meet the standards are driven away from the first limiting ring through the separation tube, so as to avoid impurities from mixing with the raw material and affecting the quality of the adhesive powder.

[0028] 2. In the above scheme, by setting a threaded sleeve, the servo motor drives the conical grinding column to rotate, which in turn drives the threaded sleeve to mesh with the turbine to rotate. The turbine then clamps the raw material that has fallen into the positioning ring onto one side of the conical grinding column. The conical grinding column grinds the raw material into rubber powder, thus completing the production of rubber powder at room temperature without the need for low-temperature treatment of the raw material with liquid nitrogen.

[0029] 3. In the above solution, by setting up a gripper, the hydraulic cylinder drives the telescopic rod to control the gripper to open and close around the positioning rod. When the raw materials are being pounded, the gripper automatically gathers the raw materials inside the mixing bin together, eliminating the need for workers to assist the equipment and saving labor costs.

[0048] 1. For example Figure 1 and Figure 2 As shown, embodiments of the present invention provide a production equipment and process for modified rubber shoe soles prepared from recycled waste rubber materials, including a support 1, a first outer shell 2 fixedly installed on the top of the support 1, a first dust cover 3 fixedly installed on the top of the first outer shell 2, a second dust cover 5 fixedly installed on one side of the first outer shell 2, a mixing chamber 4 fixedly installed at the bottom of the second dust cover 5, a screening mechanism 6 provided inside the first dust cover 3, a grinding mechanism 7 provided inside the second dust cover 5, and a mixing and pressing mechanism 8 provided inside the mixing chamber 4;

[0049] The screening mechanism 6 is located at the top of the second dust cover 5, the grinding mechanism 7 is located at the bottom of the screening mechanism 6, and the mixing and pressing mechanism 8 is located at the bottom of the grinding mechanism 7. The mixing and pressing mechanism 8 is located at the bottom of the support 1 and the bottom of the first outer shell 2.

[0050] like Figure 3 and Figure 4As shown, the technical solution provided by the present invention includes a screening mechanism 6 comprising a first limiting ring 601, a separation tube 602, a centrifugal chamber 603, a paddle 604, and a feeding hopper 606. The first limiting ring 601 is fixedly installed at the bottom of the first dust cover 3. The separation tube 602 is fixedly installed on one side of the first limiting ring 601. The centrifugal chamber 603 is fixedly installed on one side of the separation tube 602. The paddle 604 is movably installed inside the centrifugal chamber 603. The feeding hopper 606 is fixedly installed at the bottom of the centrifugal chamber 603.

[0051] The screening mechanism 6 also includes a first rotating shaft 605, a second rotating shaft 607, and a servo motor 608. The servo motor 608 is fixedly installed on the top of the second dust cover 5. The top of the servo motor 608 is keyed to the second rotating shaft 607, and the top of the second rotating shaft 607 is keyed to the first rotating shaft 605.

[0052] Further explanation is needed: during the rotation of the blade 604, smaller impurities will be separated from the first limiting ring 601 through the separation tube 602, and during the rotation of the blade 604, larger pieces of raw material will be pushed out of the centrifuge chamber 603. After being blocked by the first limiting ring 601, they will enter the centrifuge chamber 603 through the gap between the first limiting ring 601 and the centrifuge chamber 603.

[0053] like Figure 5 , Figure 6 and Figure 7 As shown, the technical solution provided by the present invention includes a grinding mechanism 7 comprising a positioning ring 701, a second outer shell 702, a guide bucket 703, a threaded sleeve 704, and a bearing ring 705. The positioning ring 701 is fixedly installed inside the second dust cover 5. The second outer shell 702 is movably installed at the bottom of the positioning ring 701. The threaded sleeve 704 is fixedly installed at the bottom of the second outer shell 702. The guide bucket 703 is provided at the bottom of the threaded sleeve 704. The bearing ring 705 is fixedly installed at the bottom of the positioning ring 701.

[0054] The grinding mechanism 7 also includes a second limiting ring 706, a positioning ring 707, a turbine 708, and a conical abrasive column 709. The second limiting ring 706 is fixedly installed at the bottom of the positioning ring 701. The positioning ring 707 is fixedly installed on one side of the second limiting ring 706. The turbine 708 is movably installed on one side of the positioning ring 707. The conical abrasive column 709 is provided on one side of the turbine 708.

[0055] The tapered frosted column 709 is fixedly sleeved on one side of the second rotating shaft 607, and the turbine 708 is movably installed on one side of the second limiting ring 706.

[0056] Further explanation is needed: When the raw material falls into the positioning ring 701, the conical abrasive column 709 rotates under the drive of the servo motor 608, grinding the raw material and processing it into adhesive powder at room temperature. The threaded sleeve 704 then drives the worm gear 708 to rotate, applying a downward force to the raw material and ensuring it remains adhered to one side of the conical abrasive column 709, preventing it from detaching. In this design, the threaded sleeve 704 serves the same purpose as the worm gear, thereby driving the threaded sleeve 704 and the worm gear 708 to rotate.

[0057] like Figure 8 and Figure 9 As shown, the technical solution provided by the present invention includes a mixing mechanism 8 comprising a hydraulic cylinder 801, a base 802, a hydraulic column 803, a pressure block 804, a connecting block 805, a telescopic rod 806, a gripper 807, a positioning rod 808, and an upper mold 809. The hydraulic cylinder 801 is fixedly installed at the bottom of the servo motor 608. The base 802 is fixedly installed at the bottom of the hydraulic cylinder 801. The hydraulic column 803 is fixedly installed at the bottom of the base 802. The pressure block 804 is fixedly installed at the bottom of the hydraulic column 803. The connecting block 805 is fixedly installed at the bottom of the base 802. The telescopic rod 806 is hinged to the bottom of the connecting block 805. The gripper 807 is hinged to the bottom of the telescopic rod 806. The positioning rod 808 is movably connected to one side of the gripper 807. The upper mold 809 is fixedly installed on one side of the positioning rod 808.

[0058] A gripper 807 is movably connected to one side of the upper mold 809, and a telescopic rod 806 is set on one side of the hydraulic column 803.

[0059] Further explanation is needed: When the hydraulic column 803 extends, it drives the gripper 807 to extend to its limit distance and then unfolds. When the hydraulic column 803 shortens, since the length of the telescopic rod 806 when it is retracted is longer than that of the hydraulic column 803, the telescopic rod 806 drives the gripper 807 to retract to the position of the upper mold 809 and gather the raw material at the bottom of the upper mold 809.

[0060] Step 1: The recycled rubber is poured into the centrifuge chamber 603 through the first dust cover 3. The servo motor 608 is started to drive the second rotating shaft 607 to rotate, which in turn drives the first rotating shaft 605 to drive the blade 604 to rotate. This causes the rubber material to rotate inside the centrifuge chamber 603. Small pieces of rubber material are separated from the first limiting ring 601 through the separation pipe 602. Large pieces of rubber material are driven by the blade 604 and fall into the discharge hopper 606 through the gap between the first limiting ring 601 and the centrifuge chamber 603.

[0061] Step 2: Large pieces of rubber raw material enter the second housing 702 through the hopper 606 and the positioning ring 701. The second rotating shaft 607 drives the conical grinding column 709 and the second housing 702 to rotate. The second housing 702 further drives the threaded sleeve 704 to rotate at the bottom of the bearing ring 705, thereby driving the turbine 708 meshed on one side of the threaded sleeve 704 to rotate. Together with the conical grinding column 709, the large pieces of raw material are stuck between the two and ground into granules.

[0062] Step 3: After the granular raw material falls onto the surface of the guide bucket 703, it enters the bottom of the mixing bin 4. By starting the hydraulic cylinder 801, the hydraulic column 803 is extended and pressed down, which drives the upper mold 809 to squeeze the raw material that has fallen to the bottom of the mixing bin 4 for preliminary processing.

[0063] Step 4: Add auxiliary materials between the first limiting ring 601 and the centrifugal chamber 603. The auxiliary materials enter the bottom of the mixing chamber 4 through the feeding hopper 606, the second outer shell 702, the guide hopper 703 and the conical grinding column 709 and mix with the raw materials.

[0064] Step 5: After the raw materials and auxiliary materials are mixed, the hydraulic cylinder 801 is started to drive the hydraulic column 803 to perform linear reciprocating motion. When the hydraulic column 803 extends, it drives the telescopic rod 806 to extend, further rotating and opening the gripper 807 around the positioning rod 808. When the upper mold 809 reaches the bottom of the mixing chamber 4, the raw materials and auxiliary materials are squeezed.

[0065] Step 6: When the hydraulic column 803 retracts, it drives the positioning rod 808 to retract. When the hydraulic column 803 retracts to the same length as the telescopic rod 806 and further retracts, the gripper 807 rotates around the positioning rod 808 and fits against the upper mold 809. At the same time, it gathers the mixture at the bottom of the mixing bin 4 to the bottom of the upper mold 809.

[0066] Step 7: By repeatedly extending and contracting the hydraulic column 803, the upper mold 809 is driven to extrude the mixture until the rubber raw material and auxiliary materials react fully to complete the modification of the rubber.

Small pieces of rubber material are separated from the first limiting ring (601) through the separation pipe (602), while large pieces of rubber material are driven by the blade (604) to fall into the discharge hopper (606) through the gap between the first limiting ring (601) and the centrifuge chamber (603). Step 2: Large pieces of rubber raw material enter the second outer shell (702) through the hopper (606) and positioning ring (701). The second rotating shaft (607) drives the conical grinding column (709) and the second outer shell (702) to rotate. The second outer shell (702) further drives the threaded sleeve (704) to rotate at the bottom of the bearing ring (705), thereby driving the turbine (708) meshed on one side of the threaded sleeve (704) to rotate. Together with the conical grinding column (709), the large pieces of raw material are stuck between the two and ground into granules. Step 3: After the granular raw material falls onto the surface of the guide bucket (703), it enters the bottom of the mixing bin (4). By starting the hydraulic cylinder (801), the hydraulic column (803) is extended and pressed down, which drives the upper mold (809) to squeeze the raw material that has fallen to the bottom of the mixing bin (4) for preliminary processing. Step 4: Add auxiliary materials between the first limiting ring (601) and the centrifugal chamber (603). The auxiliary materials enter the bottom of the mixing chamber (4) through the feeding hopper (606), the second outer shell (702), the guide hopper (703) and the conical grinding column (709) to mix with the raw materials. Step 5: After the raw materials and auxiliary materials are mixed, the hydraulic cylinder (801) is started to drive the hydraulic column (803) to perform linear reciprocating motion. When the hydraulic column (803) extends, it drives the telescopic rod (806) to extend, further rotating and opening the gripper (807) around the positioning rod (808). When the upper mold (809) reaches the bottom of the mixing chamber (4), the raw materials and auxiliary materials are squeezed. Step 6: When the hydraulic column (803) retracts, it drives the positioning rod (808) to retract. When the hydraulic column (803) retracts to the same length as the telescopic rod (806) and further retracts, the gripper (807) rotates around the positioning rod (808) and fits against the mold (809). At the same time, it gathers the mixture at the bottom of the mixing bin (4) to the bottom of the mold (809). Step 7: By repeatedly extending and contracting the hydraulic column (803), the upper mold (809) is driven to extrude the mixture until the rubber raw material and auxiliary materials react fully to complete the modification of the rubber.
