Description

Technical Field

[0001] This utility model relates to the field of material slitting technology, and in particular to a rubber particle slitting device. Background Technology

[0002] In modern industrial systems, rubber, plastics, and other rubber compounds are indispensable basic materials, widely used in automobile manufacturing, electronics, footwear, building materials, and other fields. As the core equipment for rubber compound molding and processing, rubber compound granulation equipment undertakes the key task of slitting rubbery raw materials into precisely sized granules. Its processing quality directly affects the finished product quality and production efficiency of downstream processes such as injection molding and extrusion molding. With the continuous increase in the requirements of various industries for the refinement and high performance of rubber compound products, as well as the demand for cost reduction and efficiency improvement brought about by intensified market competition, the inherent defects of traditional rubber compound granulation equipment are becoming increasingly prominent.

[0003] In the complete process of rubber particle slitting, the pretreatment stage before the rubber enters the slitting zone plays a decisive role in the final slitting quality. Most mainstream slitting equipment on the market currently adopts a rough operation mode of "direct conveying-slitting". In this mode, the rubber material enters the slitting mechanism directly from the storage silo or mixing process. During the storage and mixing process, due to fluctuations in the formula ratio and differences in the uniformity of mixing, the rubber material is prone to uneven texture. Some areas have high hardness, while others have excessive elasticity. These differences cause uneven stress and local deformation when the rubber material runs on the conveyor belt. In addition, the rubber material itself is sticky. Under the action of gravity, thicker rubber material layers may sag and wrinkle, while thinner areas are prone to tearing or curling under the friction of the conveyor belt. Thus, when the untreated rubber material enters the slitting area, due to the uneven surface, the slitting blades are subjected to excessive load when contacting the raised parts, and there is a phenomenon of empty cutting when encountering the concave areas. Ultimately, this results in uneven particle size, which cannot meet the stringent requirements of sealing components for particle precision. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a rubber particle slitting device that can solve the problem that when untreated rubber enters the slitting zone, due to the uneven surface, the slitting blade is subjected to excessively high load when contacting the protruding part, and when it encounters the concave area, it will have a hollow cutting phenomenon, which ultimately leads to the particle size being uneven and unable to meet the stringent requirements of sealing components for particle precision.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber granule slitting device, comprising a granule slitting machine body, a baffle plate, a slitting mechanism, a feeding mechanism, a guiding mechanism, and a support base, wherein a pre-compression shaping component is provided on the support base;

[0006] The pre-compression shaping assembly includes a support frame, a cylinder, a pre-compression roller, and a support frame. Two fixing bolt slots are opened on the upper surface of both sides of the support seat. The outer walls of the protrusions on both sides of the lower end of the support frame are threaded with fixing bolts. A transport roller assembly is installed inside the upper surface of the support seat, and a cylinder is fixedly installed on the outer wall of the upper end of the support frame.

[0007] The two outer walls of the support frame are slidably connected to the two inner walls of the support frame. Two T-shaped block grooves are opened on both inner walls of the support frame. Two T-shaped blocks are fixedly connected to the two outer walls at the upper end of the support frame. A control panel is fixedly installed on the upper surface of one side of the support frame.

[0008] Preferably, the support frame is U-shaped, the support bracket is U-shaped, and the two ends of the preload roller are rotatably connected to the inner walls of the two sides of the support bracket via rotating shafts;

[0009] The support frame is installed on the upper surface of the support base by four fixing bolts that fit into the corresponding fixing bolt slots.

[0010] Preferably, the transport roller assembly consists of multiple transport rollers and a drive mechanism, and the outer walls of the four T-blocks are slidably connected to the interior of the corresponding T-block grooves;

[0011] The cylinder's output end slides into the interior of the support frame and is fixedly connected to the upper surface of the support frame.

[0012] Preferably, the cylinder is electrically connected to the control panel, and the preload roller is used in conjunction with the transport roller on the transport roller assembly;

[0013] Among them, the two sliding rods that are slidably connected to the upper surface of the support frame extend into the interior of the support frame at the end near the support frame and are fixedly connected to the upper surface of the support frame.

[0014] Preferably, the feeding mechanism is installed at the front end of the pellet slitting machine body;

[0015] One side of the support base is connected to the feeding mechanism via a transport roller assembly, and the guiding mechanism is installed on the front feeding mechanism of the main body of the pellet slitting machine.

[0016] Preferably, the slitting mechanism is installed at the rear end of the main body of the pellet slitting machine, and a rubber roller is installed below the slitting mechanism at the rear end of the main body of the pellet slitting machine.

[0017] Among them, a baffle plate is installed above the cutting mechanism at the rear end of the main body of the pellet slitting machine.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: When the rubber granules in the pre-compression shaping component are conveyed to the area below the pre-compression roller, the control panel controls the extension and retraction of the cylinder output end according to the preset program, pushing the support frame to slide along the T-shaped block groove on the inner wall of the support frame, thereby driving the pre-compression roller to move downward. In coordination with the transport roller of the transport roller assembly, pressure is applied to the rubber granules, causing the rubber granules to move forward continuously under the conveying force of the transport roller assembly, while being subjected to the downward pressure of the pre-compression roller. Under the clamping and squeezing action of the two, the shape of the rubber granules is regularized, making their thickness uniform and their surface flat, creating conditions for subsequent precise slitting. The pre-compressed rubber granules are thus completed, avoiding the phenomenon of empty cutting when encountering concave areas due to uneven surfaces after the rubber enters the slitting area, thereby improving the practicality and reliability of the equipment.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a rubber granule slitting device, including a granule slitting machine body 1, a baffle plate 2, a slitting mechanism 3, a feeding mechanism 4, a guiding mechanism 5, and a support base 7;

[0028] The support base 7 is equipped with a pre-compression shaping component;

[0029] The pre-compression shaping assembly includes a support frame 9, a cylinder 11, a pre-compression roller 13, and a support frame 14. The support frame 9 is U-shaped, and two fixing bolt slots 16 are provided on the upper surfaces of both sides of the support base 7. Fixing bolts 10 are threaded onto the outer walls of the protrusions on both sides of the lower end of the support frame 9. The support frame 14 is U-shaped, and the two ends of the pre-compression roller 13 are rotatably connected to the inner walls of both sides of the support frame 14 via rotating shafts. The support frame 9 is installed on the upper surface of the support base 7 by four fixing bolts 10 engaging with the corresponding fixing bolt slots 16. A transport roller assembly 8 is installed inside the upper surface of the support base 7. The transport roller assembly 8 consists of multiple transport rollers and a drive mechanism. A cylinder 11 is fixedly installed on the upper outer wall of the support frame 9. The outer walls of both sides of the support frame 14 are connected to the support... The inner walls on both sides of the frame 9 are slidably connected. Two T-shaped block grooves 17 are opened on both sides of the inner walls of the support frame 9. Two T-shaped blocks 15 are fixedly connected to the outer walls on both sides of the upper end of the support frame 14. The outer walls of the four T-shaped blocks 15 are slidably connected to the interior of the corresponding T-shaped block grooves 17. The output end of the cylinder 11 extends slidably into the interior of the support frame 9 and is fixedly connected to the upper surface of the support frame 14. A control panel 12 is fixedly installed on one side of the upper surface of the support frame 9. The cylinder 11 is electrically connected to the control panel 12. The pre-pressing roller 13 is used in conjunction with the transport roller on the transport roller assembly 8. The two sliding rods slidably connected to the upper surface of the support frame 9 extend slidably into the interior of the support frame 9 and are fixedly connected to the upper surface of the support frame 14.

[0030] The feeding mechanism 4 is installed at the front end of the pellet slitting machine body 1. One side of the support base 7 cooperates with the feeding mechanism 4 through the transport roller assembly 8. The guiding mechanism 5 is installed on the feeding mechanism 4 at the front end of the pellet slitting machine body 1. The slitting mechanism 3 is installed at the rear end of the pellet slitting machine body 1. A rubber roller 6 is installed below the slitting mechanism 3 at the rear end of the pellet slitting machine body 1. A baffle plate 2 is installed above the slitting mechanism 3 at the rear end of the pellet slitting machine body 1. The support frame 9 is U-shaped, and the support frame 14 is U-shaped. The two ends of the pre-pressure roller 13 are rotatably connected to the inner walls of the two sides of the support frame 14 through rotating shafts. The support frame 9 is installed on the upper surface of the support base 7 through four fixing bolts 10 and the corresponding fixing bolt grooves 16.

[0031] Furthermore, when using this device, firstly, the support frame 9 is installed on the support base 7 using fixing bolts 10. The fixing bolts 10 cooperate with the fixing bolt slots 16 on the support base 7 to ensure the stability of the support frame 9. At this time, the support frame 14 is slidably connected to the T-shaped block slots 17 on the inner wall of the support frame 9 through T-shaped blocks 15. The two ends of the pre-pressing roller 13 are rotatably connected to the support frame 14, forming the execution structure for pre-pressing and shaping. Then, the cylinder 11 is adjusted through the control panel 12 on the upper surface of one side of the support frame 9. According to the thickness, hardness and other parameters of the rubber particles to be processed, the initial extension and retraction of the cylinder 11 is set so that the pre-pressing roller 13 and the transport roller of the transport roller assembly 8 form a spacing that is suitable for the pre-pressing requirements of the rubber particles, preparing for subsequent pre-pressing operations. The drive mechanism of the starting conveyor roller assembly 8 causes multiple conveyor rollers of the conveyor roller assembly 8 to start rotating, establishing the power foundation for conveying rubber granules. At the same time, the drive device of the slitting mechanism 3 at the rear end of the granule slitting machine body 1 is started, enabling the slitting mechanism 3 to meet the slitting operation conditions. Then, the rubber granules to be slitted are placed on the conveyor rollers of the conveyor roller assembly 8. The drive mechanism of the conveyor roller assembly 8 drives the conveyor rollers to rotate. Relying on the friction between the conveyor rollers and the rubber granules, the rubber granules are continuously conveyed forward, gradually approaching the area below the pre-compression roller 13. When the rubber granules are conveyed to the area below the pre-compression roller 13, the control panel 12 controls the cylinder 11 to operate according to the preset program. The output end of the cylinder 11 extends and retracts, pushing the support frame 14 to slide along the T-shaped block groove 17 on the inner wall of the support frame 9. The pre-compression roller 13 moves downwards, cooperating with the conveyor rollers of the conveyor roller assembly 8 to apply pressure to the rubber particles. This causes the rubber particles to continuously move forward under the conveying force of the conveyor roller assembly 8, while simultaneously being subjected to the downward pressure of the pre-compression roller 13. Under the clamping and squeezing action of both, the shape of the rubber particles becomes regular, resulting in uniform thickness and a smooth surface, creating conditions for subsequent precise slitting. The pre-compressed rubber particles continue to be conveyed forward with the conveyor roller assembly 8, leaving the pre-compression area. Then, the pre-compressed rubber particles are conveyed by the conveyor roller assembly 8 to the feeding mechanism 4. The guiding mechanism 5 installed on the feeding mechanism 4 then begins to function. Through its own structure, the guiding mechanism 5 corrects the position and guides the direction of the rubber particles, ensuring that the rubber particles are accurately aligned with the conveyor rollers of the feeding mechanism 4. The feeding channel is used to prevent deviation. Then, the feeding mechanism 4, in conjunction with the conveyor roller assembly 8, receives the pre-compressed rubber granules from the conveyor roller assembly 8. Using its own conveying power, the granules are further conveyed to the feeding port of the slitting mechanism 3 at the rear end of the granulator body 1, achieving precise transfer of the pre-compressed and shaped rubber granules to the slitting area. When the granules reach the slitting mechanism 3, the drive device of the slitting mechanism 3 drives the slitting cutter to move according to the set slitting parameters, cutting the pre-compressed, precisely guided rubber granules into finished products that meet production requirements. Simultaneously, during the slitting process, the rubber roller 6 below the slitting mechanism 3 at the rear end of the granulator body 1 rotates synchronously, providing auxiliary conveying power to the rubber granules through contact with them.To ensure smooth conveying of rubber particles during slitting and prevent conveying blockages due to slitting resistance, the baffle plate 2 above the slitting mechanism 3 prevents rubber particles from splashing during the slitting operation. It also limits and guides the rubber particles, ensuring orderly slitting within the slitting area.

[0032] When the rubber particles are conveyed to the pre-pressure roller 13 through the pre-pressure shaping component, the control panel 12 controls the output end of the cylinder 11 to extend and retract according to the preset program. This pushes the support frame 14 to slide along the T-shaped block groove 17 on the inner wall of the support frame 9, causing the pre-pressure roller 13 to move downward. In coordination with the transport roller of the transport roller assembly 8, pressure is applied to the rubber particles, causing them to move forward continuously under the conveying force of the transport roller assembly 8. At the same time, they are subjected to the downward pressure of the pre-pressure roller 13. Under the clamping and squeezing action of the two, the shape of the rubber particles is regularized, making their thickness uniform and their surface flat. This creates conditions for subsequent precise slitting. The pre-pressed rubber particles are thus prevented from being cut empty when encountering concave areas due to uneven surfaces after entering the slitting area, thereby improving the practicality and reliability of the equipment.
