Description

Technical Field

[0001] This invention relates to the field of vulcanization technology, and in particular to a large-stroke fabric storage mechanism for a drum vulcanizing machine. Background Technology

[0002] A drum vulcanizing machine is a specialized piece of equipment used for the continuous vulcanization of strip materials such as rubber, plastics, and fabrics. In a vulcanization production line, to ensure continuous operation and accommodate speed matching between upstream and downstream processes (such as unwinding, vulcanizing, and rewinding) as well as temporary shutdowns, a fabric storage mechanism is typically installed before or after the drum vulcanizing machine. The function of the fabric storage mechanism is to buffer a certain length of material. When the upstream material feed rate differs from the downstream demand rate, it can maintain the continuity of the production line and tension stability by releasing or storing material.

[0003] Existing fabric storage mechanisms typically have a short storage stroke and often employ a fixed multi-roller structure, where material is buffered by alternately winding between upper and lower fixed rollers. However, this type of structure has significant drawbacks: First, due to the fixed roller spacing, the storage capacity is limited, making it difficult to adapt to large speed fluctuations or prolonged downtime for roll changes. This often necessitates slowing down or even stopping the production line, severely impacting production efficiency. Second, the lack of real-time monitoring and automatic adjustment capabilities for material tension, relying heavily on manual intervention, leads to unstable tension control, easily causing material stretching deformation or wrinkling, affecting the final product quality. Third, for applications requiring ultra-long storage strokes, simply increasing the frame height or the number of rollers results in bulky equipment, high manufacturing costs, and increased risk of deviation due to long-distance material transport. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a large-stroke fabric storage mechanism for a drum vulcanizing machine, which has a large fabric storage stroke, can automatically control constant tension, and has a compact structure.

[0005] To achieve the above objectives, the present invention proposes a large-stroke fabric storage mechanism for a drum vulcanizing machine, comprising a fabric storage frame and an adaptive fabric storage mechanism disposed on the fabric storage frame. A winding mechanism is provided next to the fabric storage frame at a position corresponding to the output end of the adaptive fabric storage mechanism. The adaptive fabric storage mechanism includes a first roller group and a second roller group disposed on the fabric storage frame and composed of several conveying rollers. The first roller group and the second roller group are arranged opposite to each other. A roller group moving mechanism is also provided on the fabric storage frame. The roller group moving mechanism is used to drive any one of the first roller group and the second roller group to reciprocate in a direction away from and closer to the other roller group, or to drive the first roller group and the second roller group to move synchronously in opposite directions and relative to each other.

[0006] Tension monitoring mechanisms for monitoring the tension of the strip material being passed through are respectively provided at the input and / or output ends of the adaptive fabric storage mechanism, and the control system controls the roller group moving mechanism based on the data from the tension monitoring mechanisms.

[0007] Preferably, the roller group moving mechanism includes a moving bracket and several lifting drive cylinders. The first roller group or the second roller group is mounted on the moving bracket. The moving bracket is movably mounted on the fabric storage frame. A lifting drive cylinder for driving the moving bracket to reciprocate is provided between the fabric storage frame and the moving bracket.

[0008] Preferably, the fabric storage frame is further provided with a secondary fabric storage mechanism. The secondary fabric storage mechanism includes a plurality of third roller groups and a fourth roller group located in the conveying path of the strip material between the first roller group and the second roller group. The third roller group is composed of a plurality of third conveying rollers, and the fourth roller group is composed of a plurality of fourth conveying rollers. The third conveying rollers are located on the upper side of the strip material, and the fourth conveying rollers are located on the lower side of the strip material. The secondary fabric storage mechanism also includes a roller control mechanism for driving the third roller group to move downward and driving the fourth roller group to move upward so that the third roller group and the fourth roller group contact the strip material and change the conveying path of the strip material.

[0009] Preferably, the roller control mechanism includes end plates located at both ends of the third roller group and the fourth roller group, and a lifting control mechanism. The end plates are vertically or obliquely provided with a plurality of first grooves corresponding to the third conveying roller and the fourth conveying roller. The ends of the third conveying roller and the fourth conveying roller are movably disposed in the first grooves. The lifting control mechanism is used to drive the third roller group and the fourth roller group to move up and down along their respective first grooves.

[0010] Preferably, the lifting control mechanism includes a plurality of rotating disks disposed on the end plate and a rotation drive structure for driving the rotating disks to rotate. The rotating disks are disposed between adjacent third conveying rollers and fourth conveying rollers. Second grooves and third grooves corresponding to the third conveying rollers and fourth conveying rollers are respectively provided on both sides of the rotating disks. The second grooves and third grooves are both arranged radially along the rotating disks. The ends of the third conveying rollers and fourth conveying rollers are respectively movably disposed in the second grooves and third grooves.

[0011] Preferably, the rotary drive structure includes a drive motor, a synchronous gear, and a synchronous transmission rod. Adjacent rotary disks are synchronously connected by synchronous gears. At least one synchronous transmission rod is provided between the end plates on both sides for synchronously connecting any of the rotary disks on both sides. The drive motor is driven and connected to any of the rotary disks.

[0012] Preferably, the adjacent rotating disks are arranged alternately.

[0013] Preferably, the tension monitoring mechanism includes a tension roller and through-shaft tension sensors located at both ends of the tension roller.

[0014] Preferably, the fabric storage frame is provided with a vertically arranged guide rod, and the movable support is provided with guide wheels at both ends for cooperating with the guide rod.

[0015] Preferably, a stopping mechanism is provided between the winding mechanism and the adaptive fabric storage mechanism. The stopping mechanism includes a stopping roller and a clamping plate disposed opposite to the stopping roller, and a clamping cylinder for driving the clamping plate to reciprocate in a direction away from and close to the stopping roller. A gap is provided between the stopping roller and the clamping plate for material to pass through.

[0016] The beneficial effects of this invention's large-stroke fabric storage mechanism for a drum vulcanizing machine are as follows: By setting up an adaptive fabric storage mechanism composed of a first roller group and a second roller group, and using a roller group moving mechanism to drive one or two roller groups to reciprocate, the relative distance between the two roller groups can be significantly changed, thereby significantly increasing the actual winding path length of the material and achieving large-stroke fabric storage. Combined with real-time data from the tension monitoring mechanism, the control system can automatically control the movement of the roller group and dynamically adjust the amount of fabric stored to adapt to changes in the production line speed. Especially when changing rolls in the winding mechanism, there is no need to slow down or stop the machine, greatly improving production efficiency and equipment utilization. Tension monitoring mechanisms are set at both the input and output ends of the adaptive fabric storage mechanism, which can monitor the tension value of the material when entering and leaving the fabric storage mechanism in real time and accurately. Based on this dual-point tension data, the control system controls the action of the roller group moving mechanism in a closed loop, thereby achieving dynamic and precise adjustment of the material tension. This effectively avoids material stretching and deformation caused by excessive tension or wrinkles and deviation caused by insufficient tension, significantly improving the quality consistency of vulcanized products. For scenarios requiring extremely long fabric storage strokes, this invention further incorporates a secondary fabric storage mechanism consisting of a third and fourth roller group and a roller control mechanism. When the conventional fabric storage stroke is insufficient, the roller control mechanism can drive the third and fourth roller groups to contact the material, actively altering the material conveying path and creating additional bending buffers. This design significantly increases the fabric storage capacity based on the original compact structure, avoiding the problems of bulkiness and high cost caused by simply increasing the frame height or the number of rollers, thus achieving a balance between compact structure and ultra-long fabric storage stroke.

[0031] Example 1:

[0032] See Figure 1 , Figure 2 The present invention discloses a large-stroke fabric storage mechanism for a drum vulcanizing machine, comprising a fabric storage frame 1 with a frame structure, an adaptive fabric storage mechanism on the fabric storage frame 1, and a plurality of delivery rollers 2 for delivering materials at both the input and output ends of the adaptive fabric storage mechanism. A winding mechanism 19 is provided next to the fabric storage frame 1 at a position corresponding to the output end of the adaptive fabric storage mechanism.

[0033] The adaptive fabric storage mechanism includes a first roller group 3 and a second roller group 4, both mounted on the fabric storage frame 1 and composed of several conveying rollers. The first roller group 3 is located below the fabric storage frame 1, and the second roller group 4 is located above the first roller group 3. A roller group moving mechanism is also provided on the fabric storage frame 1 to drive the second roller group 4 to reciprocate in a direction away from and closer to the first roller group 3. In use, the material alternately passes over the conveying rollers of the first roller group 3 and the second roller group 4, and is then conveyed to the winding mechanism 19 for winding. The relative distance between the first roller group 3 and the second roller group 4 is controlled by the roller group moving mechanism, thereby controlling the material buffer amount.

[0034] To achieve automatic control, see [reference] Figure 2 , Figure 4 Tension monitoring mechanisms 5 are respectively installed at the input and output ends of the adaptive fabric storage mechanism to monitor the tension of the strip material passing through. The control system controls the roller group moving mechanism based on the data from the tension monitoring mechanisms 5. The tension monitoring mechanisms 5 automatically control the operation of the roller group moving mechanism based on the data from the tension monitoring mechanisms 5 at both ends of the adaptive fabric storage mechanism. When the tension is lower than a preset value, the roller group moving mechanism controls the second roller group 4 to move away from the first roller group 3, thereby increasing the stroke until the material is tensioned to the preset value. When the tension is higher than the preset value, the roller group moving mechanism controls the second roller group 4 to move closer to the first roller group 3, reducing the material stroke.

[0035] See Figure 1 , Figure 3 A stopping mechanism is provided at the winding mechanism. The stopping mechanism includes a stopping roller 16 and a clamping plate 17 opposite to the stopping roller 16, and a clamping cylinder 18 for driving the clamping plate 17 to reciprocate away from and towards the stopping roller 16. A gap is provided between the stopping roller 16 and the clamping plate 17 for material to pass through. When the clamping cylinder 18 drives the clamping plate 17 to move towards the stopping roller 16, the material can be clamped by the cooperation of the clamping plate 17 and the stopping roller 16, keeping one end of the material fixed. When the winding mechanism finishes winding one roll and needs to stop to switch to the next new roll, the material near the winding mechanism end can be clamped by the stopping mechanism. Then, the position of the second roller group 4 can be adjusted by the roller group moving mechanism to gradually increase the material stroke to buffer the incoming material at the front end, without stopping the machine and improving efficiency.

[0036] Specifically, the roller assembly moving mechanism includes a moving bracket 6 and two lifting drive cylinders 7 respectively vertically arranged at both ends of the moving bracket 6. The second roller assembly 4 is mounted on the moving bracket 6, which is movably mounted on the fabric storage frame 1. A lifting drive cylinder 7 for driving the moving bracket 6 to reciprocate is provided between the fabric storage frame 1 and the moving bracket 6. The vertical movement of the moving bracket 6 is controlled by the extension and retraction of the cylinder arm of the lifting drive cylinder 7, thereby adjusting the height of the second roller assembly 4 and thus adjusting the distance between the second roller assembly 4 and the first roller assembly 3.

[0037] The fabric storage frame 1 is provided with a vertically arranged guide rod 15, and the movable support 6 is provided with guide wheels 61 at both ends for cooperating with the guide rod 15. The movable support 6 is moved and limited by the cooperation between the guide wheels 61 and the guide rod 15, so as to achieve stable movement of the movable support 6.

[0038] For details regarding the specific structure of tension monitoring mechanism 5, please refer to [link / reference]. Figure 4 The tension monitoring mechanism 5 includes a tension roller 51 and through-shaft tension sensors 52 located at both ends of the tension roller 51. Material passes through the surface of the tension roller 51, and the tension data of the tension roller 51 is sensed by the through-shaft tension sensors 52.

[0039] Example 2:

[0040] Based on Example 1, see [link / reference] Figures 5-8 In order to further improve the fabric storage performance, a secondary fabric storage mechanism is provided on the fabric storage frame 1 in this embodiment. Specifically, the secondary fabric storage mechanism includes a third roller group 8 and a fourth roller group 9 located in the strip material conveying path between the first roller group 3 and the second roller group 4. The third roller group 8 is composed of a plurality of third conveying rollers 81, and the fourth roller group 9 is composed of a plurality of fourth conveying rollers 91. The third conveying rollers 81 are located on the upper side of the strip material, and the fourth conveying rollers 91 are located on the lower side of the strip material. The secondary fabric storage mechanism also includes a roller control mechanism for driving the third roller group 8 to move downward and driving the fourth roller group 9 to move upward so that the third roller group 8 and the fourth roller group 9 come into contact with the strip material and change the strip material conveying path. When the secondary fabric storage mechanism is not in operation, the rollers of the third roller group 8 and the fourth roller group 9 do not contact the material, thereby reducing the conveying resistance. However, when the adaptive fabric storage mechanism cannot meet the material buffering requirements, the secondary fabric storage mechanism is activated. The roller control mechanism of the secondary fabric storage mechanism controls the rollers of the third roller group 8 to descend and the rollers of the fourth roller group 9 to rise. The rollers of the third roller group 8 and the fourth roller group 9 then come into contact with the material, causing the material conveying path to bend, thereby increasing the material buffering capacity again to meet greater material buffering requirements.

[0041] Specifically, the roller control mechanism includes end plates 10 located at both ends of the third roller group 8 and the fourth roller group 9, and a lifting control mechanism. The end plates 10 are vertically arranged, and several first grooves 101 corresponding to the third conveying roller 81 and the fourth conveying roller 91 are vertically formed on the end plates 10. The ends of the third conveying roller 81 and the fourth conveying roller 91 are movably disposed within the first grooves 101. The lifting control mechanism is used to drive the third roller group 8 and the fourth roller group 9 to move up and down along their respective first grooves 101. The first grooves 101 cooperate with the third conveying roller 81 and the fourth conveying roller 91 to limit the movement of the conveying rollers, so that the third conveying roller 81 and the fourth conveying roller 91 can move up and down along a predetermined path.

[0042] For details on the specific structure of the lifting control mechanism, please refer to [link / reference]. Figure 5 , Figure 6 and Figure 7 The lifting control mechanism includes several rotating disks 11 disposed on the end plate 10 and a rotation drive structure for driving the rotating disks 11 to rotate. The rotating disks 11 are disposed between adjacent third conveying rollers 81 and fourth conveying rollers 91. Adjacent third conveying rollers 81 and fourth conveying rollers 91 share a rotating disk 11. The rotating disk 11 has a second groove 111 and a third groove 112 on both sides, corresponding to the third conveying rollers 81 and fourth conveying rollers 91, respectively. The second groove 111 and the third groove 112 are both arranged radially along the rotating disk 11. The ends of the third conveying rollers 81 and fourth conveying rollers 91 are respectively movably disposed in the second groove 111 and the third groove 112. The second trough 111 and the third trough 112 have a corresponding communication position with the first trough 101. The ends of the third conveying roller 81 and the fourth conveying roller 91 are set in the corresponding communication position. When the rotating disk 11 rotates, the second trough 111 and the third trough 112 also rotate and switch positions. During this process, the corresponding communication position between the second trough 111, the third trough 112 and the first trough 101 also changes. Through the cooperation of the second trough 111, the third trough 112 and the first trough 101, the third conveying roller 81 and the fourth conveying roller 91 are driven to move up and down along the first trough 101.

[0043] The rotary drive structure includes a drive motor 14, a synchronous gear 12, and a synchronous transmission rod 13. Adjacent rotary disks 11 are synchronously connected via the synchronous gear 12. A synchronous transmission rod 13 is provided between the end plates 10 on both sides to synchronously connect any one of the rotary disks 11. The drive motor 14 is driven by any one of the rotary disks 11. This rotary drive structure synchronously connects all the rotary disks 11 together, and all the rotary disks 11 can be driven to rotate synchronously by a single drive motor 14, saving costs, improving synchronization, and facilitating control.

[0044] To avoid interference between the rotating disks 11, adjacent rotating disks 11 are staggered.

[0045] Working process of this invention:

[0046] In the operation of a drum vulcanizing machine with a large stroke, the present invention provides a strip material that is fed into an adaptive storage mechanism and passes sequentially around the first roller group 3, the second roller group 4, the third roller group 8, and the fourth roller group 9. Then, it is wound up by a winding mechanism 19. The operation of the roller group moving mechanism is automatically controlled based on the data from the tension monitoring mechanism 5 at both ends of the adaptive storage mechanism. When the tension is lower than the preset value, the roller group moving mechanism controls the second roller group 4 to move away from the first roller group 3, thereby increasing the stroke until the material is tensioned to the preset value. When the tension is higher than the preset value, the roller group moving mechanism controls the second roller group 4 to move closer to the first roller group 3, thereby reducing the material stroke.

[0047] When the adaptive fabric storage mechanism cannot meet the demand, the secondary fabric storage mechanism is activated. The roller control mechanism of the secondary fabric storage mechanism controls the rollers of the third roller group 8 to descend and the rollers of the fourth roller group 9 to rise. The rollers of the third roller group 8 and the fourth roller group 9 come into contact with the material and bend the material conveying path, thereby increasing the material buffer capacity again to meet the greater material buffer demand.
