Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of rubber ring processing technology, and more specifically, to a soft and hard rubber composite extruder for producing rubber rings. Background Technology

[0002] In the field of rubber product manufacturing, rubber rings are key components widely used in many industries such as automobiles, machinery, and construction. Their performance directly affects the quality and service life of related products. In the traditional rubber ring production process, the material often accumulates at the feed inlet due to gravity and its own characteristics, resulting in poor feeding and affecting production continuity and efficiency. Ordinary feeding devices cannot effectively solve the problem of material agglomeration, resulting in uneven distribution of material entering the extruder, which in turn leads to inconsistent rubber ring quality.

[0003] During the extrusion stage, conventional extruders face challenges when compounding soft and hard rubber compounds. Due to the large differences in the properties of soft and hard rubber compounds, it is difficult to achieve uniform mixing and stable extrusion, resulting in inconsistent performance of different parts of the rubber ring. When subjected to external forces such as pressure and tension, local damage is likely to occur, reducing product reliability. Furthermore, when processing rubber rings with complex shapes, traditional extruders have difficulty accurately controlling the rubber flow rate and extrusion volume, resulting in a high scrap rate.

[0004] In the material collection stage, ordinary collection methods are inefficient, and rubber rings are prone to scattering and piling up. This not only increases the cost of manual handling, but may also cause damage to the surface of the rubber rings due to collisions, affecting their appearance and quality. The collection device lacks effective positioning and fixation, and is prone to shaking during the collection process, further reducing the collection effect. In order to overcome these bottlenecks and improve the production quality and efficiency of rubber rings, it is urgent to develop a new type of soft and hard rubber composite extruder for rubber ring production. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a soft and hard rubber composite extruder for the production of rubber rings, which solves the technical problem that in the traditional rubber ring production process of the prior art, the material often accumulates at the feed inlet due to gravity and its own characteristics, resulting in poor feeding, affecting the continuity and efficiency of production. Ordinary feeding devices cannot effectively solve the problem of material agglomeration, resulting in uneven distribution of material entering the extruder, and thus causing inconsistent quality of rubber rings.

[0006] According to one aspect, at least one embodiment of this disclosure provides a soft and hard rubber composite extruder for producing rubber rings, comprising:

[0007] The extruder body has a frame at its lower end;

[0008] A discharge insertion positioning assembly is disposed on the side wall of the equipment frame;

[0010] The discharge insertion positioning assembly includes an insertion cavity, which is opened on the side wall of the equipment frame. A positioning frame is provided at the inner bottom edge of the insertion cavity. A flipping frame is provided on the inner side wall of the positioning frame. A push-in plate is provided on the side wall of the flipping frame. A return spring is provided on the lower end face of the flipping frame.

[0011] As a further technical solution, an insert groove is provided at the top inner part of the insertion cavity, a push spring is provided inside the insert groove, and a positioning strip is provided at the lower end of the push spring.

[0012] As a further technical solution, the oscillating feeding assembly includes a feeding hood, which is disposed at the feed inlet of the extruder body. A conical hood is disposed inside the feeding hood, and an oscillating box is disposed on the side wall of the conical hood. An oscillating motor is disposed inside the oscillating box, and a rotating disk is disposed at the output end of the oscillating motor. A centrifugal groove is disposed on the side wall of the rotating disk.

[0013] As a further technical solution, the side wall of the equipment frame is provided with a discharge chute, and the position of the discharge chute corresponds to that of the insertion cavity.

[0014] As a further technical solution, a collection box is inserted into the insertion cavity, and a sliding wheel is provided on the lower end face of the collection box, the width of which matches the width of the insertion cavity.

[0015] As a further technical solution, the discharge port of the extruder body corresponds to the position of the discharge chute, and the width of the discharge chute matches the width of the insertion cavity.

[0016] As a further technical solution, the inner wall of the feed hood has a sliding cavity, and the outer wall of the conical hood is provided with a limiting ring, which is embedded inside the sliding cavity.

[0017] As a further technical solution, the number of the oscillation boxes is several, and the multiple oscillation boxes are evenly arranged on the outer side wall of the conical cover.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, through the design of the oscillating feeding component, the oscillating motor drives the rotating disk and centrifugal tank to generate periodic vibration, which is transmitted to the material through the conical cover, effectively preventing the material from accumulating at the feed inlet. This oscillating feeding method keeps the material in a loose state and allows it to enter the extruder body evenly, solving the problem of poor feeding caused by material agglomeration in traditional feeding devices.

[0020] 2. In this disclosure, the coordinated work of the extruder body and the discharge insertion positioning component perfectly addresses the differences in properties between soft and hard rubber materials. The screw structure and heating system inside the extruder can precisely control the plasticization and mixing degree of soft and hard rubber materials, ensuring consistent performance of each part of the composite rubber ring. The coordinated design of the discharge chute and the collection box inside the insertion cavity, through the linkage of components such as the flipping frame, return spring, and positioning strip, achieves precise guidance and stable collection of the rubber ring semi-finished product.

[0028] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0033] 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.

[0034] like Figures 1-5 As shown, it illustrates a soft and hard rubber composite extruder for producing rubber rings according to this disclosure, comprising:

[0035] The extruder body 1 has a frame 2 at its lower end.

[0036] The discharge insertion positioning component 3 is installed on the side wall of the equipment frame 2;

[0037] The oscillating feed assembly 4 is installed on the extruder body 1;

[0038] The discharge insertion positioning assembly 3 includes an insertion cavity 3-1, which is located on the side wall of the equipment frame 2. A positioning frame 3-2 is provided at the bottom inner edge of the insertion cavity 3-1. A flipping frame 3-3 is provided on the inner side wall of the positioning frame 3-2. A push-in plate 3-4 is provided on the side wall of the flipping frame 3-3. A return spring 3-5 is provided on the lower end face of the flipping frame 3-3.

[0039] The oscillating feed assembly 4 includes a feed hood 4-1, which is located at the feed inlet of the extruder body 1. A conical hood 4-2 is provided inside the feed hood 4-1. An oscillating box 4-3 is provided on the side wall of the conical hood 4-2. An oscillating motor 4-4 is provided inside the oscillating box 4-3. A rotating disk 4-5 is provided at the output end of the oscillating motor 4-4. A centrifugal groove 4-6 is provided on the side wall of the rotating disk 4-5.

[0040] In some examples, the extruder body 1 is securely mounted on the upper end of the equipment frame 2 by means of bolts or welding. The equipment frame 2 is usually made of metal, such as steel, with sufficient strength and stability to support the weight and vibration of the extruder body 1 during operation. The equipment frame 2 not only provides support for the extruder body 1, but also isolates it from the ground to prevent damage that may be caused by direct contact between the extruder body 1 and the ground. It also facilitates the movement and maintenance of the equipment. The insertion cavity 3-1 is precisely machined into the side wall of the equipment frame 2 to ensure its dimensional accuracy and surface flatness. The positioning frame 3-2 is fixed to the inner bottom edge of the insertion cavity 3-1 by welding or bolting. The shape and size of the positioning frame 3-2 are designed according to the requirements of the collection box 9 or subsequent docking equipment. It is generally a rectangular frame structure. The insertion cavity 3-1 is used to insert into the collection box 9 or dock with other equipment to realize the collection of rubber ring discharge or the connection of subsequent processing. The positioning frame 3-2 provides a positioning reference for the collection box 9 or docking equipment to ensure its accurate insertion and installation.

[0041] The tilting frame 3-3 is mounted on the inner wall of the positioning frame 3-2 via a rotatable connection such as a pin or hinge, ensuring that it can be tilted flexibly. The push plate 3-4 is welded or bolted to the side wall of the tilting frame 3-3. One end of the return spring 3-5 is connected to the lower end face of the tilting frame 3-3, and the other end is fixed to the corresponding position of the positioning frame 3-2 or the equipment frame 2. When the collection box 9 is inserted into the insertion cavity 3-1, the front end of the collection box 9 will push the push plate 3-4, causing the tilting frame 3-3 to rotate around the pin and compress the return spring 3-5. When the collection box 9 is inserted into place, the tilting frame 3-3 automatically resets under the action of the return spring 3-5, which plays a certain role in limiting and fixing the collection box 9. When it is necessary to remove the collection box 9, the tilting frame 3-3 is pushed again to release it from the limitation on the collection box 9, making it easy to remove the collection box 9.

[0042] The feed hood 4-1 is fixed to the feed inlet of the extruder body 1 by bolts or welding to ensure a good seal and prevent material leakage. The conical hood 4-2 is installed inside the feed hood 4-1. It can be installed by setting a groove on the inner wall of the feed hood 4-1, with the edge of the conical hood 4-2 embedded in the groove, or by using a connecting rod to fix the conical hood 4-2 to the inner wall of the feed hood 4-1. The feed hood 4-1 guides the material into the extruder body 1 and also prevents the material from spilling during feeding. The design of the conical hood 4-2 helps the material to move under gravity. The material slides down and can change the distribution state of the material, making it enter the extruder body 1 more evenly. The vibration box 4-3 is fixed to the side wall of the conical cover 4-2 by bolts or welding. The vibration motor 4-4 is installed inside the vibration box 4-3. Its output end is fixed to the rotating disk 4-5 by coupling or key connection, etc., to ensure that the motor can stably drive the rotating disk 4-5 to rotate. The side wall of the rotating disk 4-5 is provided with centrifugal grooves 4-6. The shape and number of centrifugal grooves 4-6 are designed according to the actual vibration requirements. They are generally circular or elliptical grooves, evenly distributed on the side wall of the rotating disk 4-5.

[0043] After the oscillating motor 4-4 starts, it drives the rotating disk 4-5 to rotate at high speed. Due to the centrifugal force, the objects (such as counterweights) located in the centrifugal tank 4-6 will generate periodic changes in centrifugal force, which will cause the oscillating box 4-3 to vibrate. This vibration is transmitted to the material through the conical cover 4-2, so that the material can remain in a loose state before entering the extruder body 1, avoiding material accumulation or blockage of the feed inlet, and improving the smoothness and uniformity of feeding.

[0044] like Figures 1-5 As shown, in this embodiment, the inner top of the insertion cavity 3-1 is provided with an insert groove 3-6, the inside of the insert groove 3-6 is provided with a push spring 3-7, and the lower end of the push spring 3-7 is provided with a positioning strip 3-8.

[0045] In some examples, the insert groove 3-6 is machined into the top of the insertion cavity 3-1, the push spring 3-7 is placed in the insert groove 3-6, and the positioning strip 3-8 is fixed to the lower end of the push spring 3-7. The positioning strip 3-8 is usually made of a material with a certain elasticity and friction, such as rubber or plastic. When the collection box 9 is inserted into the insertion cavity 3-1, the positioning strip 3-8 presses down on the top of the collection box 9 under the action of the push spring 3-7, further enhancing the stability of the collection box 9 in the insertion cavity 3-1 and preventing it from shaking or shifting during the collection process.

[0046] For example, such as Figure 1 As shown, the side wall of the equipment frame 2 is provided with a discharge chute 5, which corresponds to the position of the insertion cavity 3-1.

[0047] In some examples, the discharge chute 5 is fixed to the side wall of the equipment frame 2 by welding or bolting. Its position corresponds to the discharge port of the extruder body 1 and the insertion cavity 3-1. The discharge chute 5 provides a guiding channel for the rubber rings extruded by the extruder body 1, so that they can accurately enter the collection box 9 or docking equipment along a predetermined path, avoiding the rubber rings from scattering or deviating during the discharge process, and improving the efficiency and accuracy of discharge.

[0048] For example, such as Figure 2 As shown, a collection box 9 is inserted into the insertion cavity 3-1. A sliding wheel 6 is provided on the lower end face of the collection box 9, and the width of the collection box 9 matches that of the insertion cavity 3-1.

[0049] In some examples, the shape and size of the collection box 9 are designed according to the size of the insertion cavity 3-1 and the actual collection needs. It is generally a cuboid or cube shape. The lower end face of the collection box 9 is equipped with a sliding wheel 6, which is connected to the collection box 9 through axle to ensure that the collection box 9 can move flexibly on the ground or other supporting surfaces. The width of the collection box 9 matches the insertion cavity 3-1 so that it can be smoothly inserted into the insertion cavity 3-1. In use, the collection box 9 is pushed to the insertion cavity 3-1 by the sliding wheel 6 and then inserted into the insertion cavity 3-1. When the rubber ring extruded by the extruder body 1 enters the collection box 9 through the discharge chute 5, after the collection box 9 is full of material, it can be pushed out of the insertion cavity 3-1 by the sliding wheel 6 for subsequent processing or transportation.

[0050] For example, such as Figure 1 As shown, the discharge port of the extruder body 1 corresponds to the position of the discharge chute 5, and the width of the discharge chute 5 matches that of the insertion cavity 3-1.

[0051] In some examples, the width of the discharge chute 5 is designed according to the size of the discharge port of the extruder body 1 and the size of the inlet of the collection box 9 or docking device, to ensure that the material can smoothly slide from the discharge port of the extruder body 1 into the discharge chute 5 and into the collection box 9 or docking device in the insertion cavity 3-1.

[0052] For example, such as Figure 3 As shown, the inner wall of the feed hood 4-1 has a sliding cavity 7, and the outer wall of the conical hood 4-2 is provided with a limiting ring 8, which is embedded inside the sliding cavity 7.

[0053] In some examples, the sliding cavity 7 is machined into the inner wall of the feed hood 4-1, and the limiting ring 8 is fixed to the outer wall of the conical hood 4-2. The size of the limiting ring 8 matches the sliding cavity 7, allowing it to slide freely within the sliding cavity 7. The cooperation between the limiting ring 8 and the sliding cavity 7 not only restricts the position of the conical hood 4-2 within the feed hood 4-1 to prevent excessive displacement, but also allows the conical hood 4-2 to have a certain amount of room to move during the oscillation process, ensuring that the oscillation effect can be effectively transmitted to the material.

[0054] For example, such as Figure 3 As shown, there are several oscillation boxes 4-3, and multiple oscillation boxes 4-3 are evenly arranged on the outer wall of the conical cover 4-2.

[0055] During use, the material is poured into the feed hood 4-1. Since a conical hood 4-2 is set inside the feed hood 4-1, the material slides down along the inner wall of the conical hood 4-2 under the action of gravity. At this time, multiple vibration chambers 4-3 installed on the side wall of the conical hood 4-2 begin to function. The vibration motor 4-4 starts and drives the rotating disk 4-5 to rotate at high speed. The counterweight in the centrifugal groove 4-6 on the side wall of the rotating disk 4-5 changes periodically due to centrifugal force, which causes the vibration chamber 4-3 to vibrate. The vibration is transmitted to the material through the conical hood 4-2, keeping the material in a loose state during the descent, avoiding accumulation and blockage of the feed inlet, and ensuring that the material can enter the feed inlet of the extruder body 1 evenly and smoothly. At the same time, the limiting ring 8 on the outer wall of the conical hood 4-2 slides in the sliding cavity 7 on the inner wall of the feed hood 4-1, which not only limits the displacement range of the conical hood 4-2, but also ensures that it can effectively transmit vibration during the vibration process.

[0056] Inside the extruder body 1, soft and hard rubber materials are heated and plasticized. The rotation of the screw drives the rubber material to be continuously compacted, mixed and conveyed in the barrel. Under the shearing and extrusion of the screw, the soft and hard rubber materials gradually reach a state suitable for extrusion and are finally extruded from the discharge port of the extruder body 1 to form a semi-finished rubber ring.

[0057] The semi-finished rubber rings extruded from the discharge port of the extruder body 1 slide down the corresponding discharge chute 5. The discharge chute 5 acts as a guide, guiding the rubber rings accurately into the insertion cavity 3-1 on the side wall of the equipment frame 2. Inside the insertion cavity 3-1, the collection box 9 is pre-push-in and positioned by the sliding wheel 6. When the collection box 9 is inserted, its front end pushes the push plate 3-4 on the tilting frame 3-3, causing the tilting frame 3-3 to rotate around the pin shaft and compress the return spring 3-5. After insertion, the tilting frame 3-3 is in place, and the return spring 3-5... Under the action of automatic reset, the collection box 9 is initially limited. At the same time, the push spring 3-7 in the top mounting groove 3-6 in the insertion cavity 3-1 pushes the positioning strip 3-8 downward to press the top of the collection box 9, further enhancing the stability of the collection box 9. The rubber ring semi-finished product slides into the collection box 9 along the discharge chute 5 to complete the collection. After the collection box 9 is full, push the flipping frame 3-3 to release it from the limitation of the collection box 9. Then the collection box 9 can be pushed out of the insertion cavity 3-1 by the sliding wheel 6 for subsequent processing or storage operations.
