Description

Technical Field

[0001] The utility model relates to an adjustable extruder for rubber products, in particular to an adjustable extruder for rubber products based on throughput control. Background Art

[0002] An extruder is a piece of machinery widely used in the manufacturing of rubber products. It transforms raw rubber into rubber products of various shapes and sizes by heating, compressing, and squeezing it. The extruder's operating principle is based on two fundamental elements: material flow and heat transfer. Raw rubber powder or granules are fed into the extruder barrel, where the rubber is heated, compressed, and extruded.

[0003] Extruders can produce continuously without interruption, resulting in high production efficiency, large output, and relatively low costs. By replacing different molds or adjusting process parameters, extruders can produce plastic and rubber products of various shapes and sizes to meet different market demands. Common extruders include screw extruders and pin-type extruders.

[0004] When using a screw extruder, the material flow is achieved by the rotation of the screw. The continuous rotation of the screw can heat, compress and extrude the rubber raw materials. However, the size and shape of the finished rubber product are controlled by the shape and size of the discharge port at the discharge end. When different products need to be produced, different discharge ends need to be replaced to meet production needs. The common replacement method is to dismantle the existing discharge end and install a discharge end with a discharge port of different size and shape. The entire replacement process is relatively cumbersome and is not conducive to controlling production efficiency. Utility Model Content

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] See also Figures 1 to 9 As an embodiment of the present invention, the adjustable rubber product extruder based on throughput control includes a chassis 1, and a plurality of barrels 2 fixedly mounted on the chassis 1, and an extrusion barrel 3 is fixedly mounted on one end of the barrel 2 away from the chassis 1;

[0044] A feeding mechanism is provided in the barrel 2;

[0045] A first discharge block 4 is fixedly mounted on the extrusion cylinder 3 , and a second discharge block 5 is disposed on the first discharge block 4 ;

[0046] The first discharge block 4 is provided with a plurality of discharge ports 401, and the second discharge block 5 is provided with a plurality of shaping ports 501; and the sizes of the shaping ports 501 decrease in equal steps;

[0047] A limiting mechanism is provided on the first discharging block 4, which can limit the rotation of the second discharging block 5; and when the limiting mechanism releases the limit on the second discharging block 5, the second discharging block 5 can be rotated to adjust the alignment of the shaping openings 501 of different sizes with the discharging opening 401;

[0048] A locking mechanism is further provided between the first discharging block 4 and the second discharging block 5 to prevent separation.

[0049] In this embodiment, rubber, additives and other production raw materials are added to the barrel 2 through the feed port 201; the feeding mechanism is used to drive the transportation and mixing of these production raw materials, and during the operation of the feeding mechanism, the rubber production raw materials will be heated and melted, so that the raw materials are fully mixed to form a fluid rubber product.

[0050] Driven by the feeding mechanism, the fluid rubber product converges toward the extrusion barrel 3. As the fluid rubber product accumulates within the extrusion barrel 3, the subsequent rubber product squeezes the preceding rubber product, causing the rubber product to flow from the discharge port 401 into the shaping port 501 and ultimately out of the shaping port 501. The shape and size of the shaping port 501 determine the shape and size of the rubber product as it flows out.

[0051] According to user needs, when the size of the rubber product needs to be changed, the locking mechanism needs to be used to release the tight fit between the first discharging block 4 and the second discharging block 5 (tight fit can prevent the rubber product from flowing into the connection seam between the first discharging block 4 and the second discharging block 5 during the outflow process, so as to prevent the rubber product from cooling in the connection seam after production is stopped, which makes it more difficult to separate the two). In the process of releasing the tight fit, the second discharging block 5 will gradually move away from the first discharging block 4. At the same time, the limiting mechanism will release the restriction on the second discharging block 5, so that the second discharging block 5 can rotate relative to the first discharging block 4.

[0052] By rotating the second discharging block 5, the size of the shaping port 501 corresponding to the discharging port 401 is changed, and then the second discharging block 5 is driven gradually closer to the first discharging block 4 through the locking mechanism until the two are tightly fitted. During this process, the limiting mechanism will simultaneously limit the second discharging block 5 to prevent the second discharging block 5 and the first discharging block 4 from rotating relative to each other.

[0053] The process of adjusting the size of the shaping port 501 aligned with the discharge port 401 is relatively simple (only the screw column 6 and the second discharge block 5 need to be rotated), and the conversion can be completed quickly, which is beneficial to improving production efficiency; through the mutual cooperation of the locking mechanism and the limiting mechanism, the rubber product can be prevented from flowing out of the connecting seam between the second discharge block 5 and the first discharge block 4, and the molding rate of the discharged rubber product can be increased, which is beneficial to improving the production quality of the extruder.

[0054] As a further solution of the present invention, the feeding mechanism includes a rotating shaft 10 rotatably mounted on the chassis 1 , and a spiral material plate 11 is fixedly mounted on the rotating shaft 10 .

[0055] In this embodiment, the side of the spiral material plate 11 away from the rotating shaft 10 is in sliding cooperation with the barrel 2, thereby improving the efficiency of conveying raw materials; the rotating shaft 10 is driven to rotate by the driving component in the chassis 1, thereby driving the spiral material plate 11 to rotate, thereby conveying the raw materials filled in the feed barrel 2 from the feed port 201 from the side of the barrel 2 close to the chassis 1 toward the extrusion barrel 3; and during the conveying process, the raw materials will be mixed under the action of the spiral material plate 11, thereby improving the quality of the finished product.

[0056] As a further solution of the present invention, the locking mechanism includes an internally threaded sleeve 503 and a slider 504 fixedly mounted on the second discharging block 5, and a rotating ring 12 is rotatably mounted on the first discharging block 4; two fixed blocks 1201 are fixedly mounted on the rotating ring 12, one of the fixed blocks 1201 is rotatably mounted with a screw column 6 threadedly connected to the internally threaded sleeve 503, and the other fixed block 1201 is fixedly mounted with a guide rod 7 slidably connected to the slider 504.

[0057] In this embodiment, the screw column 6 is rotated, and through the thread cooperation with the internal threaded sleeve 503, the internal threaded sleeve 503 is driven to gradually move away from or approach the fixed block 1201, thereby driving the second discharging block 5 to gradually move away from or approach the first discharging block 4, and at the same time, it can drive the slider 504 on the guide rod 7 to move away from or approach the fixed block 1201.

[0058] By rotating the screw column 6 to drive the second discharging block 5 away from the first discharging block 4, the limit mechanism on the second discharging block 5 can be released; by rotating the screw column 6 to drive the second discharging block 5 close to the first discharging block 4 until the two are tightly fitted, it can avoid excessive rubber pressure in the extrusion cylinder 3 and pushing the second discharging block 5 away from the first discharging block 4, thereby improving the production efficiency and quality of the extruder.

[0059] As a further solution of the present invention, the limiting mechanism includes a plurality of limiting rods 402 fixedly mounted on the first discharging block 4, and the second discharging block 5 is provided with a rotating groove 502 that slides with the limiting rod 402, and a plurality of limiting blocks 506 are fixedly mounted in the rotating groove 502.

[0060] As a further solution of the present invention, the length of the limiting block 506 is smaller than the depth of the rotating groove 502 , and the limiting block 506 is away from the first discharging block 4 .

[0061] In this embodiment, when the second discharging block 5 is tightly fitted with the first discharging block 4, the limiting rod 402 is located in the rotating groove 502, and the limiting block 506 is in close contact with the limiting rod 402, and the limiting block 506 limits the limiting rod 402 in the rotating groove 502 so that the discharge port 401 and the shaping port 501 remain aligned; in the process of driving the second discharging block 5 away from the first discharging block 4 by rotating the screw column 6, the limiting rod 402 will slide outward in the rotating groove 502. Since the length of the limiting block 506 is less than the depth of the rotating groove 502, the limiting rod During the outward sliding process of 402, the limit rod 402 will separate from the limit block 506, so that the limit block 506 releases the restriction on the limit rod 402, and then the second discharging block 5 is rotated. At this time, the limit rod 402 will make a circular motion in the rotating groove 502, thereby changing the size of the shaping mouth 501 aligned with the discharging port 401, and when the shaping mouth 501 is aligned with the discharging port 401, the limit rod 402 is just located between the two limit blocks 506. During the rotation process of the second discharging block 5, the rotating ring 12 will be driven to rotate on the first discharging block 4 through the screw column 6.

[0062] By rotating the screw column 6, the second discharge block 5 is driven close to the first discharge block 4 until the two are tightly fitted. During this process, the limit rod 402 will slide inward in the rotating groove 502, and during the sliding process, the limit rod 402 and the limit block 506 slide and fit together. The limit rod 402 is limited by multiple limit blocks 506, thereby avoiding positional displacement between the discharge port 401 and the shaping port 501 during the outflow of the rubber product, thereby improving the quality of the finished product of the extruder.

[0063] As a further solution of the present invention, a locking groove 403 is provided on the limit rod 402, and a plurality of sliding grooves 505 corresponding to the shaping mouth 501 are provided in the rotating groove 502. A prompt block 8 that cooperates with the locking groove 403 is slidably engaged in the sliding groove 505, and a spring 9 that is fixedly connected to the prompt block 8 is fixedly installed in the sliding groove 505.

[0064] In this embodiment, when the limiting rod 402 makes a circular motion in the rotating groove 502, the limiting rod 402 will resist and squeeze the prompt block 8, causing the prompt block 8 to slide inward in the slide groove 505, compressing the spring 9. When another shaping port 501 of a different size is aligned with the discharge port 401, the engaging groove 403 will be aligned with the slide groove 505, and the limiting rod 402 will stop squeezing the prompt block 8. At this time, under the elastic force of the spring 9, the prompt block 8 will slide outward in the slide groove 505, and finally the prompt block 8 will enter the engaging groove 403, thereby increasing the difficulty of rotating the second discharge block 5, and can further improve the alignment degree between the discharge port 401 and the shaping port 501, so as to improve product quality.

[0065] As a further solution of the present invention, the extrusion cylinder 3 is in a conical column shape, and the diameter of the side away from the barrel 2 is smaller.

[0066] In this embodiment, as the cross-section of the extrusion barrel 3 decreases, the pressure inside the extrusion barrel 3 will increase, and the speed at which the fluid rubber flows from the extrusion barrel 3 into the discharge port 401 will increase, thereby preventing the rubber from being interrupted, thereby improving product quality and production efficiency.

[0067] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
