Description

Technical Field

[0001] This invention relates to the field of adhesive processing equipment technology, and more specifically, to an environmentally friendly recycled rubber extrusion equipment. Background Technology

[0002] As an important strategic material, rubber is subject to strict control by all countries. Therefore, the utilization of waste rubber is of profound significance for overcoming the scarcity of rubber resources and promoting recycling. In order to make full use of environmentally friendly recycled rubber, extrusion equipment is needed to extrude waste rubber into new shapes.

[0003] Among the existing published documents, patent publication number CN106142382A discloses an environmentally friendly desulfurization extruder for recycled rubber. This patent addresses the issue that while the recycled rubber industry is developing rapidly, most enterprises suffer from outdated production equipment and technology, leading to failure to meet environmental standards, wastewater and waste gas emissions, environmental pollution, and negative impacts on the public. Furthermore, most enterprises are large-scale but have low production efficiency. There is an urgent need for a superior recycled rubber production line to address the environmental pollution caused by the waste rubber industry and to achieve high-efficiency production. The patent describes a design where an overfeeding device is installed at the right end of the barrel screw, and a twin-screw cooling extruder is installed below it. A waste recycling device is installed in the middle of the base and is connected to the inside of the barrel screw via a pipe. The left side of the twin-screw cooling extruder is sequentially equipped with a distribution box, a lower gearbox, and a lower motor. All components—the distribution box, lower gearbox, lower motor, and twin-screw cooling extruder—are mounted on a sliding rail via a bracket located on the base, enabling dynamic installation. However, this patent has the following drawbacks.

[0004] When the above-mentioned extrusion equipment is in use, it can extrude environmentally friendly recycled rubber through the screw along the inner wall of the feeder barrel. However, with long-term use, the entire inside of the feeder barrel will be in long-term contact with the rubber, causing damage to its inner wall. Maintenance personnel need to disassemble and repair it. Since the inside of the feeder barrel is relatively deep, it is difficult to repair the inside of the feeder barrel, and the later maintenance is relatively inconvenient. Therefore, an environmentally friendly recycled rubber extrusion equipment is needed. Summary of the Invention

[0005] To overcome the above-mentioned defects of the prior art, the present invention provides an environmentally friendly recycled rubber extrusion device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an environmentally friendly recycled rubber extrusion device, comprising a plurality of first extrusion sealing arc blocks, a plurality of second extrusion sealing arc blocks on one side of the first extrusion sealing arc blocks, a linkage mixing component at the top of the second extrusion sealing arc blocks, and linkage rotating blocks fixed on opposite sides of the second extrusion sealing arc blocks and the first extrusion sealing arc blocks, wherein a linkage maintenance mechanism is provided at the top of the linkage rotating blocks;

[0007] The linkage maintenance mechanism includes a limiting rotating shaft set at the top of the linkage rotating block, a connecting support block fixed on one side of the linkage rotating block, multiple limiting linkage rods fixed at the bottom end of the connecting support block, and a transmission gear plate meshing with the outer wall of the limiting linkage rod. A first transmission rod is welded inside the limiting rotating shaft, and a drive motor is coaxially connected to the top end of the first transmission rod. A moving component is provided between the first extrusion sealing arc block and the second extrusion sealing arc block, near their center point.

[0008] Preferably, the first extrusion sealing arc block and the second extrusion sealing arc block are in extrusion contact, and a sealing rubber strip is provided between the first extrusion sealing arc block and the second extrusion sealing arc block and near their edge line. The two adjacent linkage rotating blocks are rotatably connected by a limiting rotating shaft, and the limiting rotating shaft is made of stainless steel.

[0009] Preferably, a connecting bracket with a vertical cross-sectional shape of Z is fixed on one side of the outer wall of the drive motor, and the connecting bracket is welded and fixed to the drive motor. A collar base plate is provided on the outer wall of the first transmission rod near its bottom end, and the collar base plate is rotatably connected to the first transmission rod through a bearing. A collar support block is provided on the outer wall of the limiting linkage rod below the connecting support block, and multiple limiting linkage rods are fixedly connected to the collar support block.

[0010] Preferably, the moving component includes a second transmission rod disposed between the first extrusion sealing arc block and the second extrusion sealing arc block and near their center point. An extrusion auger is welded to the outer wall of the second transmission rod. A reduction extrusion motor is coaxially connected to one end of the second transmission rod. A sealing ring is connected to the outer wall of the reduction extrusion motor at a position on one side of the second extrusion sealing arc block. An extrusion ring is adhered to one side of the sealing ring. A linkage bracket is welded to one side of the extrusion ring. A threaded collar block is welded to the bottom end of the linkage bracket. A transmission screw is threadedly connected to the inside of the threaded collar block. A servo drive motor is coaxially welded to one end of the transmission screw. A rectangular frame plate is rotatably connected to the outer wall of the transmission screw near the servo drive motor via a bearing. The outer wall of the threaded collar block and the inner wall of the rectangular frame plate are horizontally slidably connected. Both the outer wall of the threaded collar block and the inner wall of the rectangular frame plate are polished.

[0011] Preferably, the linkage mixing assembly includes a first guide arc plate disposed at the top of the second extrusion sealing arc block, and a second guide arc plate with its bottom end welded and fixed to the top of the first extrusion sealing arc block is provided on one side of the first guide arc plate. A first guide sealing plate is welded to the top of the first guide arc plate, and a second guide sealing plate is welded to the top of the second guide arc plate. A stirring shaft is provided between the second guide sealing plate and the first guide sealing plate, and multiple linkage stirring rods are distributed in a ring-like manner on the outer wall of the stirring shaft. A mixing motor is coaxially fixed to the top of the stirring shaft. A sleeve support plate is rotatably connected to the outer wall of the stirring shaft and located at the top of the second guide sealing plate through a bearing. The second guide arc plate and the first guide arc plate are in extrusive contact, and the first guide sealing plate and the second guide sealing plate are in extrusive contact.

[0012] The technical effects and advantages of this invention are as follows:

[0013] This invention employs a linkage maintenance mechanism that causes a drive motor to rotate a first transmission rod, which in turn rotates multiple transmission gear discs. A linkage rotating block drives a limiting rotating shaft to rotate on another linkage rotating block. Furthermore, the linkage rotating block can move a second extrusion sealing arc block. Multiple first extrusion sealing arc blocks can also form a linkage, and the inner walls of both the first and second extrusion sealing arc blocks can be moved to external positions for maintenance and inspection. This makes maintenance more convenient.

[0014] This invention uses a movable component to start the servo drive motor to drive the transmission screw to rotate forward. The transmission screw drives the threaded collar block to move to the left along the inner wall of the rectangular frame plate under the action of the thread. The sealing ring no longer squeezes and contacts the first extrusion sealing arc block and the second extrusion sealing arc block. The extrusion auger moves to the left from the circular gap between the first extrusion sealing arc block and the second extrusion sealing arc block, which facilitates the maintenance and replacement of the extrusion auger.

[0015] The present invention employs a linkage mixing component that enables the first extrusion sealing arc block and the second extrusion sealing arc block to move to the right and separate, thereby separating the first guide arc plate and the second guide arc plate. The first guide sealing plate and the second guide sealing plate begin to separate, and the second guide sealing plate drives the sleeve support plate to move the stirring shaft, which facilitates the maintenance of the inner walls of the first guide arc plate and the second guide arc plate.

[0016] In summary, through the interaction of the above-mentioned multiple functions, firstly, the inner walls of both the first and second extrusion sealing arc blocks can be moved to the external position, then the extrusion auger moves to the left from the circular gap between the first and second extrusion sealing arc blocks, and finally the first and second guide arc plates will separate, and the first and second guide sealing plates will begin to separate. In summary, the extrusion equipment is more convenient to maintain. Attached Figure Description

[0027] As attached Figure 1-8 The diagram shows an environmentally friendly reclaimed rubber extrusion device. This device is equipped with a linked maintenance mechanism, a moving component, and a linked mixing component. The specific structural configuration of each mechanism and component is as follows:

[0028] In some embodiments, as shown in the appendix Figure 1-8 As shown, the linkage maintenance mechanism includes a limiting rotating shaft 4 set at the top of the linkage rotating block 3, a connecting support block 5 fixed on one side of the linkage rotating block 3, multiple limiting linkage rods 6 fixed at the bottom of the connecting support block 5, and a transmission gear 7 meshing with the outer wall of the limiting linkage rod 6. A first transmission rod 8 is welded inside the limiting rotating shaft 4, and a drive motor 9 is coaxially connected to the top of the first transmission rod 8. A moving component is provided between the first extrusion sealing arc block 1 and the second extrusion sealing arc block 2 and near their center point.

Adjacent linkage rotating blocks 3 are rotatably connected by the limiting rotating shaft 4, and the limiting rotating shaft 4 is made of stainless steel.

[0029] In some embodiments, as shown in the appendix Figure 1-4As shown, a connecting bracket 10 with a vertical cross-section of Z-shaped is fixed to one side of the outer wall of the drive motor 9, and the connecting bracket 10 is welded and fixed to the drive motor 9 so that the connecting bracket 10 can support the drive motor 9 and increase the stability of the drive motor 9. A collar base plate 11 is provided on the outer wall of the first transmission rod 8 near its bottom end, and the collar base plate 11 is rotatably connected to the first transmission rod 8 through a bearing so that the first transmission rod 8 can rotate stably inside the collar base plate 11 to achieve a stable driving effect. A collar support block 12 is provided on the outer wall of the limiting linkage rod 6 below the connecting support block 5. Multiple limiting linkage rods 6 are fixedly connected to the collar support block 12 so that the limiting linkage rod 6 drives the collar support block 12 to drive, and at the same time the limiting linkage rod 6 drives the connecting support block 5 to drive the linkage rotating block 3.

[0030] In some embodiments, as shown in the appendix Figure 5-7 As shown, the moving component includes a second transmission rod 14 located between the first extrusion sealing arc block 1 and the second extrusion sealing arc block 2, near their center point. An extrusion auger 13 is welded to the outer wall of the second transmission rod 14. A reduction extrusion motor 15 is coaxially connected to one end of the second transmission rod 14. A sealing ring 16 is connected to the outer wall of the reduction extrusion motor 15, located on one side of the second extrusion sealing arc block 2. An extrusion ring 17 is bonded to one side of the sealing ring 16. A linkage bracket 18 is welded to one side of the extrusion ring 17. A threaded collar block 19 is welded to the bottom end of the linkage bracket 18. A transmission screw 20 is threadedly connected to the inside of the threaded collar block 19. A servo drive motor 22 is coaxially welded to one end of the transmission screw 20. A rectangular frame plate 21 is rotatably connected to the outer wall of the transmission screw 20, near the servo drive motor 22, via a bearing. The outer wall of the threaded collar block 19 and the inner wall of the rectangular frame plate 21 are horizontally slidably connected. Both the outer wall of the threaded collar block 19 and the inner wall of the rectangular frame plate 21 are polished.

[0031] In some embodiments, as shown in the appendix Figure 1-8As shown, the linkage mixing assembly includes a first guide arc plate 23 disposed at the top of the second extrusion sealing arc block 2, and a second guide arc plate 24 disposed on one side of the first guide arc plate 23, the bottom end of which is welded and fixed to the top of the first extrusion sealing arc block 1. A first guide sealing plate 25 is welded to the top of the first guide arc plate 23, and a second guide sealing plate 26 is welded to the top of the second guide arc plate 24. A stirring shaft 27 is disposed between the second guide sealing plate 26 and the first guide sealing plate 25, and a plurality of linkage stirring rods 28 are distributed in a ring-like manner on the outer wall of the stirring shaft 27. A mixing motor 30 is coaxially fixed to the top of the stirring shaft 27. A sleeve support plate 29 is rotatably connected to the outer wall of the stirring shaft 27 at the top position of the second guide sealing plate 26 via a bearing. The second guide arc plate 24 and the first guide arc plate 23 are in extrusion contact, and the first guide sealing plate 25 and the second guide sealing plate 26 are in extrusion contact.

[0032] The working principle of this invention is as follows:

[0033] When the environmentally friendly recycled rubber is extruded, the heated recycled rubber is introduced into the position between the first guide sealing plate 25 and the second guide sealing plate 26. The mixing motor 30 is started to drive the stirring shaft 27 to rotate stably inside the sleeve support plate 29. The stirring shaft 27 drives more linkage stirring rods 28 to rotate. The multiple linkage stirring rods 28 can rotate and mix the environmentally friendly recycled rubber. The environmentally friendly recycled rubber flows down through the gap between the first guide arc plate 23 and the second guide arc plate 24 into the circular gap between the first extrusion sealing arc block 1 and the second extrusion sealing arc block 2. Then, the deceleration extrusion motor 15 is started to drive the second transmission rod 14 to drive. The second transmission rod 14 drives the extrusion auger 13 to rotate. In this way, the extrusion auger 13 can squeeze the environmentally friendly recycled rubber, allowing the environmentally friendly recycled rubber to move to the right and be discharged through the circular gap channel between the first extrusion sealing arc block 1 and the second extrusion sealing arc block 2. When the environmentally friendly recycled rubber is squeezed out, it can play the role of extrusion discharge of environmentally friendly recycled rubber.

[0034] When performing maintenance on the extrusion auger 13, the servo drive motor 22 can be started to drive the transmission screw 20 to rotate forward. The transmission screw 20 drives the threaded collar block 19 to move to the left along the inner wall of the rectangular frame plate 21 under the action of the thread. At the same time, the threaded collar block 19 drives the linkage bracket 18 to move to the left. The linkage bracket 18 drives the extrusion ring 17 to move the sealing ring 16 to the left. The sealing ring 16 no longer presses against the first extrusion sealing arc block 1 and the second extrusion sealing arc block 2. In this way, a gap is created between the sealing ring 16 and the second extrusion sealing arc block 2. At the same time, the extrusion ring 17 drives the second transmission rod 14 to move the extrusion auger 13 to the left. The extrusion auger 13 moves out to the left from the circular gap between the first extrusion sealing arc block 1 and the second extrusion sealing arc block 2. This makes it convenient to perform maintenance and replacement on the outside of the extrusion auger 13.

[0035] When repairing the extrusion part, two drive motors 9 can be started. The drive motors 9 drive the first transmission rod 8 to rotate, the first transmission rod 8 drives multiple transmission gear discs 7 to rotate, and the first transmission rod 8 rotates stably inside the collar base plate 11. The multiple transmission gear discs 7 drive the limiting linkage rod 6 to drive, the limiting linkage rod 6 drives the collar support block 12 to drive, and the limiting linkage rod 6 drives the connecting support block 5 to drive the linkage rotating block 3. The linkage rotating block 3 drives the limiting rotating shaft 4 to rotate on another linkage rotating block 3, and the linkage rotating block 3 can drive the second extrusion sealing arc block 2 to move. In this way, multiple second extrusion sealing arc blocks 2 can be linked, and multiple first extrusion sealing arc blocks 1 can also be linked. In this way, the inner wall of the second extrusion sealing arc block 2 can be moved to the external position, and the inner wall of the first extrusion sealing arc block 1 can also be exposed to the external position. This makes it easier to repair and inspect the first extrusion sealing arc block 1 and the second extrusion sealing arc block 2.

[0036] When the second guide arc plate 24 and the first guide arc plate 23 are separated, as the first extrusion sealing arc block 1 and the second extrusion sealing arc block 2 move to the right and separate, the first guide arc plate 23 and the second guide arc plate 24 will also separate. At the same time, the first guide sealing plate 25 and the second guide sealing plate 26 begin to separate. The second guide sealing plate 26 drives the sleeve support plate 29 to move the stirring shaft 27. The stirring shaft 27 drives the linkage stirring rod 28 to move. This achieves rapid unfolding and separation, which facilitates the maintenance of the inner wall of the first guide arc plate 23 and the inner wall of the second guide arc plate 24.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
