Description

Technical Field

[0001] This utility model relates to the field of rubber extrusion winding technology, specifically to a rubber storage rack and an extrusion cold winding device. Background Technology

[0002] In current cold-winding processes for rubber compounds, a storage rack structure is required to prevent rubber compound deformation and match the production cycle of tires. Traditional storage racks typically consist of two frames with rollers mounted on them, storing the rubber compound as it winds around them. While this setup utilizes a separate frame structure, the rollers on the frames are in a passive rotation state, causing stretching of the rubber compound as it passes through, affecting overall winding accuracy. Furthermore, the feed point of the storage rack cannot respond promptly to speed mismatches in the extrusion system, also leading to rubber compound stretching. Utility Model Content

[0003] The main purpose of this invention is to provide a rubber material storage rack and an extrusion cold wrapping device to solve the problem of rubber material stretching in the existing storage rack.

[0004] To achieve the above objectives, according to one aspect of the present invention, a rubber material storage rack is provided, comprising: a main frame; a first frame; a second frame, the first frame and / or the second frame being movably connected to the main frame, the first frame and the second frame being able to move relatively closer or further apart to form a storage space for storing material, rollers being provided on the first frame and the second frame, and the rubber material passing around the rollers to be stored in the storage space; a frame drive member, the frame drive member being drivenly connected to the first frame and / or the second frame, and driving the first frame and the second frame to move relatively closer or further apart to change the size of the storage space; and a roller drive member, the rollers on the first frame and / or the second frame being drivenly connected to the roller drive member, the roller drive member driving the rollers to actively rotate to adjust the state of the rubber material.

[0005] Furthermore, the rollers on the first frame and the second frame are both driven connected to a roller drive component. There is one roller drive component, and the rollers on the first frame and the second frame are driven connected to the same roller drive component; or there are multiple roller drive components, and the rollers on the first frame and the second frame are driven connected to different roller drive components respectively.

[0006] Furthermore, the rubber storage rack also includes a feeding mechanism, which is located on the upstream side of the storage space. The rubber enters the storage space through the feeding mechanism and is wound around the roller.

[0007] Furthermore, the feeding mechanism includes: a feeding roller, which is rotatably configured so that the rubber material passes around the feeding roller; a feeding drive, which is drivenly connected to the feeding roller and is capable of changing the rotational speed of the feeding roller; and the feeding drive, the frame drive, and the roller drive are electrically connected to each other.

[0008] Furthermore, the feeding mechanism also includes a feeding detection element, which is located at the feeding roller and detects the conveying status of the rubber material.

[0009] Furthermore, the rubber storage rack also includes a discharge mechanism located downstream of the storage space, through which the rubber is output from the storage space.

[0010] Furthermore, the discharge mechanism includes: a discharge roller, which is rotatably configured and is a passive roller through which the rubber material passes; and a discharge detection element, which is located at the discharge roller and detects the conveying status of the rubber material.

[0011] Furthermore, the rubber storage rack also includes a control component, which is electrically connected to the frame drive component and the roller drive component, and controls the drive state of the frame drive component and the roller drive component.

[0012] Furthermore, the rubber storage rack also includes an isolation layer disposed on the circumferential outer side of the roller, which is used to contact the rubber.

[0013] According to another aspect of the present invention, an extrusion cold wrapping apparatus is provided, including the aforementioned rubber material storage rack.

[0014] By employing the technical solution of this utility model, a frame drive component and a roller drive component are provided. The frame drive component drives the relative movement between the first and second frames, thereby changing the size of the storage space between them. This allows the rubber material to be tensioned or released, and the storage length of the rubber material can be changed, thus matching the overall conveying state of the rubber material to a certain extent. The roller drive component drives the roller to rotate actively, so that the roller can rotate accordingly when the first and second frames separate and close. This allows the separation and closing of the frames to coordinate with the active rotation of the rollers, enabling the storage frame to match the conveying speed of the rubber material in the storage space when there are accelerations or decelerations at the front and rear workstations. This avoids rubber material stretching, ensures the smoothness and consistency of the rubber material conveying throughout the process, and allows the rubber material to be wound onto the drum in its original state, improving the tire processing quality.

[0025] To address the problem of rubber stretching in existing storage racks, this invention provides a rubber storage rack and an extrusion cold wrapping device.

[0026] like Figures 1 to 4The illustrated rubber storage rack includes a main frame 10, a first frame 20, a second frame 30, a frame drive component, and a roller drive component. The first frame 20 and / or the second frame 30 are movably connected to the main frame 10. The first frame 20 and the second frame 30 can move relatively closer or further apart to form a storage space for storing rubber. Rollers 21 are provided on the first frame 20 and the second frame 30, and the rubber material passes around the rollers 21 to be stored in the storage space. The frame drive component is driven to the first frame 20 and / or the second frame 30 and drives the first frame 20 and the second frame 30 to move relatively closer or further apart to change the size of the storage space. The rollers 21 on the first frame 20 and / or the second frame 30 are driven to the roller drive component, and the roller drive component drives the rollers 21 to rotate actively to adjust the state of the rubber material.

[0027] This embodiment incorporates a frame drive and a roller drive. The frame drive drives the relative movement between the first frame 20 and the second frame 30, thereby changing the size of the storage space between them. This allows the rubber material to be tensioned or released, and the storage length of the rubber material can be altered, thus matching the overall conveying state of the rubber material to a certain extent. The roller drive drives the roller 21 to rotate actively, so that the roller 21 rotates accordingly when the first frame 20 and the second frame 30 separate and join. This coordination between the separation and joining of the frames and the active rotation of the roller 21 ensures that when there is acceleration or deceleration at the front and rear workstations, the storage frame can match the conveying speed of the rubber material in the storage space, preventing rubber material stretching and ensuring the smooth and consistent conveying of the rubber material throughout the process. This allows the rubber material to be wound onto the drum in its original state, improving the tire processing quality.

[0028] like Figure 3 As shown, multiple rollers 21 are provided, and multiple rollers 21 are provided on both the first frame 20 and the second frame 30. The rollers 21 on the same frame can be arranged at intervals in a direction perpendicular to the moving direction of the first frame 20, which is beneficial to increasing the storage capacity.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the rollers 21 on the first frame 20 and the second frame 30 are both connected to the roller drive component. In this way, the roller drive component can actively drive the rollers 21 on the first frame 20 and the second frame 30, making all rollers 21 active rollers. This helps to improve the adaptability of the entire storage space to the speed changes of the front and rear workstations, ensuring that the rubber material in all parts of the storage space can be transported smoothly and avoiding stretching.

[0030] Of course, depending on the actual situation, the roller 21 on one of the two frames, the first frame 20 and the second frame 30, can be driven and matched with the roller drive component to act as the active roller, while the roller 21 on the other frame can act as the passive roller. In this case, the rubber material storage rack will have a reduced ability to adjust the rubber material, but the overall structure will be simpler and suitable for scenarios where the adjustment range is small.

[0031] Optionally, the number of roller drive components can be set as needed, either one or more. When only one roller drive component is set, the rollers 21 on the first frame 20 and the second frame 30 are driven and connected to the same roller drive component, allowing the roller drive component to adjust all rollers 21 simultaneously. When multiple roller drive components are set, the rollers 21 on the first frame 20 and the second frame 30 can be driven and connected to different roller drive components, allowing the state of the rollers 21 on the first frame 20 and the second frame 30 to be adjusted independently without affecting each other, thus improving the adjustment capability and the adaptability to fluctuations in rubber material conveying. Of course, the rollers 21 on the first frame 20 can also be divided into multiple groups, and the rollers 21 in different groups can be driven and connected to different roller drive components, allowing the rollers 21 at different positions on the first frame 20 to be adjusted separately.

[0032] It should be noted that in this embodiment, the adjustment of the frame drive and roller drive on the frame and roller 21 is related to the preceding and following workstations. For example, when the material conveying speed of the subsequent workstation increases, the frame drive can drive the first frame 20 and the second frame 30 to move closer to each other, thereby reducing the tension between the materials. At the same time, the roller drive can drive the roller 21 to rotate faster, so that the material can be conveyed more quickly in the storage space, thus matching the speed of the subsequent workstation.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the rubber storage rack also includes a feeding mechanism 40, which is located upstream of the storage space. The feeding mechanism 40 can realize the pre-conveying of the rubber. During the conveying of the rubber, the rubber first enters the feeding mechanism 40, and then enters the storage space through the feeding mechanism 40 and is wound around the roller 21 in the storage space.

[0034] The feeding mechanism 40 in this embodiment includes a feeding roller 41 and a feeding drive. The feeding roller 41 is rotatably configured, and the rubber material passes around the feeding roller 41. The feeding drive is driven to the feeding roller 41, so that the feeding roller 41 is an active roller. The feeding roller 41 can actively drive the rubber material to be conveyed. In this way, on the one hand, the feeding roller 41 can drive the rubber material to be conveyed into the storage space to achieve the effect of active material storage. On the other hand, the conveying state such as the rotation speed of the feeding roller 41 can be adjusted and changed by the feeding drive, so that the state of the rubber material can also be adjusted during feeding. This can be used to compensate for the change in the length of the rubber material caused by the change in system speed and avoid the stretching of the rubber material.

[0035] The feeding mechanism 40 in this embodiment also includes a feeding detection element, which is installed at the feeding roller 41 and detects the conveying status of the rubber material. The feeding detection element can be equipped with a speed sensor, a vision recognition system, etc., as needed, so as to detect the status, size, and other parameters of the rubber material entering the storage space, achieving real-time monitoring.

[0036] In this embodiment, the rubber storage rack also includes a discharge mechanism 50, which is located downstream of the storage space. The rubber is output from the storage space to the outside via the discharge mechanism 50.

[0037] like Figure 1 and Figure 4 As shown, the discharge mechanism 50 of this embodiment includes a discharge roller 51 and a discharge detection element 52. The discharge roller 51 is rotatably mounted, and the rubber material passes around the discharge roller 51. In this embodiment, no driving element is provided on the discharge mechanism 50. Therefore, unlike the aforementioned active roller 41, the discharge roller 51 is a passive roller. By adopting a non-powered design for the discharge roller 51, it can better match the subsequent processes and avoid the stretching of the rubber material due to deviations between the two processes. The discharge detection element 52 is located at the discharge roller 51 and detects the conveying status of the rubber material, realizing real-time monitoring of the rubber material conveying.

[0038] The rubber material storage rack in this embodiment also includes a control component, which may include components such as a controller. The control component is electrically connected to the frame drive, roller drive, and feeding drive, so that the feeding drive, frame drive, and roller drive can cooperate with each other. The control component controls the driving state of the feeding drive, frame drive, and roller drive according to the rubber material conveying status at the preceding and following processes, thereby controlling the opening and closing action of the frame, the rotation speed of the roller 21, the rotation speed of the feeding roller 41, etc., so that the rubber material storage rack can move in a unified and coordinated manner to achieve closed-loop control.

[0039] In this embodiment, the adhesive storage rack also includes an isolation layer, which is disposed on the outer circumferential side of the roller 21, and an isolation layer is disposed on all circumferential sides of the roller 21. The isolation layer is used to directly contact the adhesive, thereby achieving the effect of preventing the adhesive from sticking together.

[0040] Each driving component mentioned in this embodiment can be a servo motor or other component as needed. The output end of the servo motor can be equipped with a transmission component to transmit the driving force to the corresponding component, thereby driving the corresponding component.

[0041] This embodiment also provides an extrusion cold winding device, including the above-mentioned rubber material storage rack. At the front and rear ends of the rubber material storage rack, winding drums, extruders and other equipment can be set as needed to cooperate in realizing the extrusion winding process of the rubber material.

[0042] In this embodiment, the rubber material storage rack's opening, closing, and lifting mechanisms are servo-controlled, and each roller 21 is also servo-controlled and independently driven, allowing for speed matching with the preceding and following processes. The storage length can be adjusted according to actual conditions, and changes in storage length do not affect the extruder's linear speed or the speed of the subsequent winding drum, ensuring that the extruder does not stop during the switching of the rear winding drum station, meeting the requirement of non-stop winding and improving overall system efficiency. The roller 21 adopts an active rotation design, matching system operation while avoiding rubber material stretching during long-path storage, ensuring that the rubber material is not passively stretched during the entire storage process, improving the working efficiency and stability of the entire winding system, and guaranteeing the final winding accuracy.

[0043] It should be noted that "multiple" in the above embodiments refers to at least two.

[0044] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0045] 1. Solve the problem of material stretching in existing material storage racks;

[0046] 2. The storage length can be adjusted according to the actual situation. The change in the storage length will not affect the linear speed of the extruder and the speed of the rear winding drum, ensuring that the extruder does not stop when the rear winding drum station is switched, meeting the requirement of non-stop winding, and improving the overall system efficiency.

[0047] 3. The roller adopts an active rotation design, which matches the system operation and avoids stretching of the rubber material during the long-path material storage process. This ensures that the rubber material is not passively stretched during the entire material storage and operation process, improves the working efficiency and stability of the entire winding system, and ensures the final winding accuracy.
