Description

Technical Field

[0001] This invention relates to the field of waste tire recycling equipment, and more particularly to a rubber coating equipment. Background Technology

[0002] Waste tires are typically processed by recycling the steel wires and rubber separately. The recycled rubber is usually made into sheets or strips, then packaged and resold. During the packaging process, the recycled rubber usually needs to be wrapped with a protective film. Current technology typically uses wrapping equipment for this process, and the wrapped rubber is then manually moved to its destination.

[0003] Existing coating equipment typically includes a conveyor to transport rubber to the target location, where the coating components then coat the rubber. However, existing technology usually coats the rubber from one side, which results in the top and bottom surfaces of the rubber not being covered by the film. Furthermore, coating from one side can easily cause misalignment of the rubber, leading to a reduction in coating quality.

[0004] Therefore, existing rubber coating equipment has the technical problem that it cannot completely coat the rubber and the rubber is prone to misalignment during the coating process. Summary of the Invention

[0005] The present invention provides a rubber coating device that solves the technical problems of existing rubber coating devices being unable to completely coat the rubber and the rubber being prone to misalignment during the coating process.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A rubber coating device includes a recycling component for recycling waste tires and outputting recycled rubber;

[0008] A guiding component for guiding a thin film, the melting point of which is lower than the melting point of the rubber to be coated;

[0009] Transmission component;

[0010] Encapsulation components;

[0011] And a discharge assembly for outputting the coated rubber;

[0012] The coating assembly includes a slide frame that contacts the film with the side of the rubber to be coated and a heat sealer that heat seals a portion of the film located on top of the rubber to be coated together.

[0013] The discharge assembly includes a carriage and a clamp disposed on the carriage;

[0014] The guiding component guides a film of a preset length to the conveying component, ensuring that the center of the film located on the conveying component is directly below the rubber output by the recycling component.

[0015] The conveying assembly conveys the film and the rubber to be coated on the film to the coating assembly, and positions the rubber to be coated directly above the slide frame;

[0016] The sliding frame slides from bottom to top relative to the rubber to be coated, so that a portion of the film contacts the side of the rubber to be coated;

[0017] The heat sealer heat seals the film located above the rubber to be coated and places a portion of the heat-sealed film on top of the rubber to be coated. The heat sealer completes the first heat seal along a first direction and then completes the second heat seal along a second direction, the first direction being opposite to the second direction.

[0018] The sliding frame moves from top to bottom and detaches from the rubber after being encapsulated;

[0019] The discharge component transfers the coated rubber to the target location. During the process of transferring the packaged rubber to the target location, the coated rubber undergoes at least one cooling process, and the cooling time is equal to the coating time of the coating component. The coating time is the time required for the coating component to complete the coating process.

[0020] Preferably, the conveying component is located at one end of the guiding component, the discharging component is located at the other end of the conveying component, and the recycling component is located on one side of the conveying component.

[0021] Preferably, the conveying assembly includes a first conveyor located outside the slide frame and a second conveyor located inside the slide frame, with a gap between the first conveyor and the second conveyor to allow the slide frame to pass through. The first conveyor is a belt conveyor and the second conveyor is a roller conveyor.

[0022] Preferably, the sliding frame includes a frame and a mounting frame, the frame being slidably connected to the mounting frame, the mounting frame being provided with a first driver for driving the frame to move up and down, the frame being provided with a guide rod for improving the motion accuracy of the frame, and the mounting frame being provided with a guide hole that cooperates with the guide rod.

[0023] Preferably, there are at least two first drivers, which are located on opposite sides of the frame, and at least four guide rods, which are evenly arranged around the frame.

[0024] Preferably, the frame is provided with rollers, which are rotatably connected to the frame. There are four rollers, which form a coating cavity through which the rubber to be coated passes. The rubber to be coated is located directly above the coating cavity, and a portion of the film is located directly above the coating cavity.

[0025] Preferably, the roller body is provided with a heater for heating the roller body, and each roller body is provided with an independent heater.

[0026] Preferably, the heat sealer includes a first heat seal assembly and a second heat seal assembly. Both the first heat seal assembly and the second heat seal assembly include a heat seal plate and a second driver that drives the heat seal plate to move relative to the rubber to be coated. Each heat seal plate is driven by an independent second driver. The first heat seal assembly and the second heat seal assembly are located on opposite sides of the rubber to be coated.

[0027] Preferably, the carriage is provided with at least two grippers, which are arranged along the length of the carriage, with a gap between adjacent grippers, and the discharge assembly further includes a third driver for driving the carriage to move.

[0028] Preferably, at least two of the grippers transfer the coated rubber to the target position in a stepwise manner, wherein the distance that each gripper transfers the coated rubber is equal to the stroke of the carriage.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] 1. By setting a guiding component, the guide component guides the film of a set length to the conveying component. After the rubber falls onto the film, the wrapping component wraps the rubber. The heat sealer is used to heat seal the film above the rubber together, so that the rubber can be completely wrapped by the film, thereby improving the performance of the rubber wrapping equipment. Furthermore, the sliding frame of the wrapping component moves from bottom to top, making it less likely for the rubber to shift during the wrapping process.

[0031] 2. By setting up a discharge component, the discharge component is used to transfer the rubber after the coating is completed to the target position. The discharge component does not require manual discharge, which prevents the heat-sealed film from burning the operators before it is completely cooled. In addition, the discharge component has completed at least one cooling of the coated rubber during the discharge process, so that the film is completely cooled before reaching the target position, which further optimizes the performance of the rubber coating equipment.

[0032] 3. By making the melting point of the film lower than that of the rubber to be coated, the melting of the rubber to be coated during the heat sealing process can be prevented, thus reducing the occurrence of defective products.

[0033] 4. The heat sealer completes the first heat seal in the first direction and then completes the second heat seal in the second direction, which makes the film heat seal effect good, the film is not easy to loosen, and improves the quality of rubber coating.

[0034] 5. By setting a sliding frame, the film around the rubber to be coated can be wrapped in one movement, so that the film around the rubber to be coated is in contact with the rubber, thus improving the coating efficiency. Attached Figure Description

[0049] The specific embodiments shown below are intended to describe various configurations of the subject matter of the invention and are not intended to represent the only configuration in which the subject matter of the invention can be practiced. The specific embodiments include particular details intended to provide a thorough understanding of the subject matter of the invention. However, it will be clear and apparent to those skilled in the art that the subject matter of the invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0050] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0051] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0052] Reference Figures 1 to 7 As shown, a rubber coating device includes a recycling component 1 for recycling waste tires and outputting recycled rubber;

[0053] The guiding component 2 is used to guide the film, the melting point of which is lower than the melting point of the rubber to be coated;

[0054] Transmission component 3;

[0055] Encapsulation component 4;

[0056] and a discharge assembly 5 for outputting the coated rubber;

[0057] The coating assembly 4 includes a sliding frame 41 that contacts the film with the side of the rubber to be coated and a heat sealer 42 that heat seals a portion of the film located on top of the rubber to be coated together.

[0058] The discharge assembly 5 includes a slide 51 and a clamp 52 disposed on the slide 51;

[0059] The discharge assembly 5, the coating assembly 4, and a portion of the conveying assembly 3 can be housed within the enclosure to improve the safety performance of the rubber coating equipment.

[0060] The steps of the rubber to be coated during the specific coating process are as follows. The sequence of actions between the above components can be controlled by a control system, which can be a computer-based control system.

[0061] Step 1: The guiding component 2 guides the film of a preset length to the conveying component 3, ensuring that the center of the film on the conveying component 3 is directly below the rubber output from the recycling component 1. The preset length refers to the length of the film that can completely wrap the rubber to be coated, and the width of the film can also completely wrap the rubber. Therefore, the film can be rectangular or square. The film first reaches the target position, that is, the center of the film is directly below the discharge port of the recycling component 1. Then, the recycling component 1 discharges the rubber. After the film reaches the target position, it usually needs to pause so that the rubber can fall to the center of the film and that the rubber has a high positional accuracy relative to the film.

[0062] Step 2: The conveying component 3 conveys the film and the rubber to be coated on the film to the coating component 4, and positions the rubber to be coated directly above the sliding frame 41. The film and the rubber on the film stop moving after reaching directly above the sliding frame 41, so that the rubber is aligned with the sliding frame 41.

[0063] Step 3: The sliding frame 41 slides from bottom to top relative to the rubber to be coated, so that a part of the film contacts the side of the rubber to be coated. During the movement of the sliding frame 41 from bottom to top, the film forms a cylindrical structure and the rubber is located inside the cylindrical structure. At this time, the bottom and side of the rubber are wrapped by the film.

[0064] Step four: The heat sealer 42 heat seals the film located above the rubber to be coated, and a portion of the heat-sealed film is located on top of the rubber to be coated. The heat sealer 42 completes the first heat seal along the first direction and then completes the second heat seal along the second direction. The first direction is opposite to the second direction. The film above the cylindrical structure can be bent to the top surface of the rubber manually or automatically. For example, it can be bent manually and then heat-sealed by the heat sealer 42. Alternatively, a bending plate can be set on the heat sealer 42. The bending plate contacts the film before the heat sealer 42. The heat sealer 42 can bend the film to the top surface of the rubber during the movement. After the heat sealer 42 reaches the top surface of the rubber, it heat seals the film to complete the coating of the rubber. The heat sealer 42 is used for heat sealing between films, not for heat sealing the film onto the rubber.

[0065] Step 5: The sliding frame 41 moves from top to bottom to detach from the rubber after being wrapped in the film;

[0066] Step six: The discharging component 5 transfers the coated rubber to the target location. During this transfer, the coated rubber undergoes at least one cooling process, and the cooling time is equal to the coating time of the coating component 4, which is the time required for the coating component 4 to complete the coating. In other words, the discharging component 5 pauses at least once while transferring the coated film. This pause allows the heat-sealed film sufficient cooling time, preventing the film from cracking due to incomplete cooling and causing the rubber coating to fail.

[0067] The coating time is the time required from when the rubber to be coated enters the coating component 4 to when the coated rubber leaves the coating component 4.

[0068] Understandably, the above steps are sequential, and the work should be carried out in the above order when applying rubber coating.

[0069] Reference Figures 3 to 7 As shown, in some embodiments, the rubber coating equipment should occupy less space in actual application. The conveying component 3 is located at one end of the guiding component 2, the discharging component 5 is located at the other end of the conveying component 3, and the recycling component 1 is located on one side of the conveying component 3.

[0070] In some embodiments, the conveying assembly 3 includes a first conveyor 31 located outside the slide frame 41 and a second conveyor 32 located inside the slide frame 41. A gap is provided between the first conveyor 31 and the second conveyor 32 to allow the slide frame 41 to pass through. The first conveyor 31 is a belt conveyor and the second conveyor 32 is a roller conveyor.

[0071] The specific structures of the first conveyor 31 and the second conveyor 32 are not limited. Their working principle and specific structure refer to existing technology. Their function is to convey the rubber to be coated and the film located under the rubber to the target position. Typically, the conveyor uses friction to convey the film and rubber to the target position to simplify the structure of the first conveyor 31 and the second conveyor 32. The dimension of the rubber along the conveying direction should be larger than the gap between the rollers in the roller conveyor. That is, the rubber should be in contact with at least two rollers simultaneously. The conveyor is usually driven by a motor.

[0072] Reference Figures 6 to 7 As shown, in some embodiments, the sliding frame 41 includes a frame 411 and a frame 412. The frame 411 is slidably connected to the frame 412. The frame 412 is provided with a first driver 413 that drives the frame 411 to move up and down. The frame 411 is also provided with a guide rod 414 to improve the movement accuracy of the frame 411. The frame 412 is provided with a guide hole that cooperates with the guide rod 414. The first driver 413 can be a device that outputs linear motion, such as a cylinder.

[0073] There are at least two first actuators 413, which are located on opposite sides of the frame 411. There are at least four guide rods 414, which are evenly arranged around the frame 411. The cross-sectional shape of the guide rods 414 can be circular.

[0074] In some embodiments, the frame 411 is provided with rollers 145, which are rotatably connected to the frame 411. There are four rollers 145, which form a coating cavity through which the rubber to be coated passes. The rubber to be coated is located directly above the coating cavity, and a portion of the film is located directly above the coating cavity.

[0075] The roller body 145 is provided with a heater for heating the roller body 145, and each roller body 145 is provided with an independent heater.

[0076] The roller body 145 can be rotatably connected to the frame 411 via a rotating shaft, and the frame 411 is provided with a shaft hole that mates with the rotating shaft. A rolling bearing can be installed between the rotating shaft and the shaft hole.

[0077] The heater is used to heat the roller 145. The temperature of the roller 145 can cause plastic deformation of the film so that the film will not expand after it is formed into a tubular shape. Usually, the temperature of the roller 145 should be lower than the heat sealing temperature of the heat sealer 42.

[0078] Reference Figures 4 to 5 As shown, in some embodiments, the heat sealer 42 includes a first heat seal assembly 421 and a second heat seal assembly 422. Both the first heat seal assembly 421 and the second heat seal assembly 422 include a heat seal plate 423 and a second driver 424 for driving the heat seal plate 423 to move relative to the rubber to be coated. Each heat seal plate 423 is driven by an independent second driver 424. The first heat seal assembly 421 and the second heat seal assembly 422 are located on opposite sides of the rubber to be coated.

[0079] The second driver 424 can be a cylinder or other device that outputs linear motion.

[0080] In some embodiments, the carriage 51 is provided with at least two grippers 52, which are arranged along the length of the carriage 51, with a gap between adjacent grippers 52. The discharge assembly 5 further includes a third driver 53 for driving the carriage 51 to move. The third driver 53 can be a device that outputs linear motion, such as an electromagnet.

[0081] At least two of the grippers 52 transfer the coated rubber to the target position in a stepwise manner, wherein the distance that each gripper 52 transfers the coated rubber is equal to the stroke of the carriage 51.

[0082] Taking two grippers 52 as an example, the rubber after coating is output from the first position of the coating assembly 4 to a position away from the first conveyor 31. The target position of the output is the second position. There is an intermediate position between the first position and the second position, which is used to cool the rubber.

[0083] The gripper 52 closer to the coating assembly 4 is the first gripper 52, and the gripper 52 farther from the coating assembly 4 is the second gripper 52. During the conveying process, the first gripper 52 first moves the coated film from a first position to an intermediate position, and then the first gripper 52 returns to the first position to prepare for the next gripping. At the same time, the second gripper 52 moves from a second position to an intermediate position. Then, the first gripper 52 and the second gripper 52 move simultaneously. The second gripper 52 moves the coated rubber from the intermediate position to the second position, and the first gripper 52 moves a piece of the coated rubber to the intermediate position.

[0084] The clamp 52 includes three movements. The first movement is a horizontal left-right movement, used to move the coated rubber; that is, the direction of the first movement is parallel to the direction of rubber movement. The second movement is a vertical movement relative to the coated rubber, used to raise or lower the coated rubber. Because the coated rubber is raised or lowered, the cooling rate of the film can be further accelerated. The second movement is typically a vertical upward movement.

[0085] The third movement is the movement of the rubber after the clamp 52 clamps the film. This refers to the movement of the clamp arm of the clamp 52 clamping or releasing the rubber after the film is clamped, which is usually also a horizontal movement.

[0086] The technical solution of the present invention and its corresponding details have been described above. It is understood that the above description is only some implementation schemes of the technical solution of the present invention, and some details may be omitted in the specific implementation.

[0087] Furthermore, in some embodiments of the above invention, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine and implement the above embodiments according to their needs to obtain a better application experience.

Obviously, these details are still within the scope of the subject matter of this invention without departing from it.
