Description

Technical Field

[0001] This utility model relates to the field of bicycle processing technology, specifically to a bicycle inner tube tread extruder. Background Technology

[0002] With the rapid development of the bicycle industry, especially the increasing demand for bicycle inner tubes, the requirements for inner tube production equipment are also rising. In the traditional inner tube production process, the extruder, as a key piece of equipment, is mainly responsible for forming the tire tread of the inner tube by heating and extruding raw materials such as rubber. However, due to the poor flowability and strong adhesion of materials during the inner tube production process, many production equipment suffer from problems such as materials not being able to be fed completely smoothly and residual materials affecting production efficiency and product quality.

[0003] Currently, most extrusion machines on the market use a single scraping device, which has poor scraping effect, resulting in a large amount of material residue on the inner wall of the extruder, thus affecting the raw material utilization rate and production efficiency during the production process. In addition, the feeding process of traditional equipment is prone to blockage or uneven material distribution, affecting the production quality and stability of inner tubes. To address these issues, a bicycle inner tube tread extruder is proposed, which uses a movable baffle to adjust the distance between itself and the discharge guide plate to solve the above problems. Utility Model Content

By optimizing the shape and layout of the scraper, and through the coordinated work of the feeding plate and scraper blocks, the material feeding efficiency and cleaning effect are significantly improved. The application of wedge-shaped scrapers and smooth metal gaskets reduces friction, improving equipment stability and energy utilization.

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0024] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Refer to the instruction manual appendix Figure 1-5 A bicycle inner tube tread extruder includes an inner tube tread extruder body 1, a feeding platform 2 on the inner tube tread extruder body 1, a feeding column 3 fixedly connected to the upper end of the feeding platform 2, a connecting column 4 fixedly connected to the upper end of the inner tube tread extruder body 1, a connecting plate 5 fixedly connected to the connecting column 4, a motor 7 fixedly connected to the connecting plate 5, a rotating rod 6 fixedly connected to the output end of the motor 7 passing through the connecting plate 5, a connecting rod 8 fixedly connected to the outer end of the rotating rod 6, and a scraper 9 fixedly connected to the connecting rod 8; driven by 07, 06 scrapes a certain extent on 09, thereby scraping away some of the material remaining inside 03 during the feeding process, allowing it to fall into 02 and 01 for processing, thus improving feeding efficiency.

[0027] Then, the scraper 9 is wedge-shaped on both sides, and the scraper 9 itself is an outward-octagonal trapezoid. The wedge shape allows the scraper 9 to gradually cut into the material that may be adhering to the column wall during rotation, while the outward-octagonal trapezoidal shape increases the contact area between the scraper 9 and the column wall, improving scraping efficiency. At the same time, this shape also helps guide the material downward during scraping, preventing material from accumulating above the scraper 9, thus ensuring normal material discharge.

[0028] Subsequently, the outer wall of scraper 9 and the inner wall of the feeding column 3 are closely fitted together, with a smooth metal gasket adhered to the outer wall of scraper 9; this tight fit ensures that scraper 9 can effectively scrape off the material on the inner wall of the feeding column 3. When the rotating rod 6 drives scraper 9 to rotate, any material adhering to the column wall cannot escape the scraping action of scraper 9. The setting of the smooth metal gasket further optimizes the contact effect between scraper 9 and column wall. On the one hand, it reduces the friction between scraper 9 and column wall, making the rotation of scraper 9 smoother, reducing the load on motor 7, and improving the energy utilization rate of the equipment. On the other hand, the smooth surface also prevents material from accumulating in the gap between scraper 9 and column wall, avoiding problems such as incomplete scraping or equipment blockage caused by material accumulation.

[0029] Next, the connecting rod 8 and scraper 9 are arranged in three groups, with the scraper 9 positioned in a triangular shape. This layout allows the scraper 9 to scrape the material from all directions on the inner wall of the feed column 3 during rotation. The three groups of scraper 9 are evenly distributed around the rotating rod 6 in a triangular arrangement, covering all areas of the column wall and ensuring no dead corners. Driven by the rotating rod 6, the three groups of scraper 9 rotate synchronously, cooperating with each other to complete the cleaning of the material on the inner wall of the feed column 3. This evenly distributed design also ensures that the material receives a uniform force during scraping, avoiding uneven material flow caused by excessive or insufficient local force, thus guaranteeing the quality and stability of the inner tube tread extrusion.

[0030] At this point, a feeding plate 10 is installed inside the feeding column 3. The feeding plate 10 is fixedly connected to the rotating rod 6 in a wound manner, and its position is at the lower columnar opening of the feeding column 3. The feeding plate 10 plays an important role in guiding the material feeding in the entire equipment. Its wound fixing method allows the feeding plate 10 to rotate synchronously with the rotation of the rotating rod 6, thereby driving the surrounding material to flow downward. The design at the lower columnar opening ensures that the material can accurately flow out of the feeding column 3 and enter the next production process. The surface of the feeding plate 10 is usually made of a smooth material, such as stainless steel or polymer plastic, to reduce the friction between the material and the feeding plate 10, allowing the material to flow more smoothly. At the same time, the shape and size of the feeding plate 10 are also carefully designed to match the internal structure of the feeding column 3, maximizing the use of the internal space and improving the material feeding efficiency.

[0031] Next, a scraper block 11 is fixedly connected to the outer wall of the feeding plate 10, and the scraper block 11 is in close contact with the inner wall of the feeding column 3. As an auxiliary scraping component of the feeding plate 10, the scraper block 11 further enhances the cleaning effect on the material on the inner wall of the feeding column 3. When the feeding plate 10 rotates with the rotating rod 6, the scraper block 11 also moves synchronously. It is tightly attached to the inner wall of the feeding column 3 and can scrape off the material that may be missed by the feeding plate 10. The tight contact between the scraper block 11 and the inner wall of the feeding column 3 ensures the effectiveness of its scraping, while its fixed connection with the feeding plate 10 ensures their coordinated work.

[0032] Secondly, the outer wall of the scraper block 11 is shovel-shaped, with the edges of the shovel-shaped portion being curved. This shovel-shaped design allows the scraper block 11 to scoop up and scrape down materials during the scraping process, much like a shovel. When the scraper block 11 moves upward, it scoops up materials adhering to the column wall, and when it moves downward, it scrapes the materials down, thus achieving bidirectional cleaning. The curved edges prevent the scraper block 11 from scratching the inner wall of the discharge column 3 during scraping, ensuring the smoothness of the column wall and facilitating smooth material flow. Simultaneously, this shovel-shaped structure can adapt to materials of varying thicknesses; whether it's a thick accumulation of material or a thin residue, the scraper block 11 can effectively clean it.

[0033] Finally, a sealing gasket is installed at the connection between the feeding platform 2 and the feeding column 3. The connection between the connecting column 4 and the inner tube tread extruder body 1 is welded, ensuring a firm and stable connection. The sealing gasket is designed to prevent material leakage at the connection between the feeding platform 2 and the feeding column 3. Since the material is in a flowing state within the equipment, if the connection is not sealed, the material may leak out, causing waste and potentially polluting the surrounding environment. The sealing gasket is typically made of materials with good sealing properties, such as rubber or silicone, which can tightly fill the gaps at the connection, forming an effective sealing barrier. The welded connection between the connecting column 4 and the inner tube tread extruder body 1 ensures the robustness of the entire equipment structure. Welding allows the connecting column 4 and the body 1 to form a solid whole, capable of withstanding greater external forces, preventing loosening or deformation during equipment operation, thus ensuring the normal operation and service life of the equipment.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
