Description

Technical Field

[0001] This utility model relates to the field of tire production technology, specifically to an automatic unlocking material winding trolley and winding device. Background Technology

[0002] Most existing tire semi-finished parts (including tread, sidewall, triangular rubber, belt layer, inner liner, shoulder pad rubber, etc.) are stored using a winding method. There are two main winding methods: one is to directly connect the H-beams to the winding device. This method has been gradually phased out because it requires manual handling between the semi-finished product area and the forming area, resulting in high labor intensity and easy loosening of products during transportation. The other method is to connect the material trolley to the winding device, integrating the small H-beams used for padding and the large H-beams used for finished products onto the material trolley. With the H-beams locked, forklifts or AGVs are used to move the material trolley, avoiding the disadvantages of high labor intensity and easy loosening of products. For example, Chinese utility model publication CN208666642U discloses a belt winding trolley. When the trolley is in a transfer or storage state, it uses a spring and friction plates to press against an I-beam coupling, achieving a locking function. When the trolley docks with the winding device, a handle needs to be manually moved. The handle drives a linkage mechanism, which in turn creates a gap between the friction plates and the I-beam coupling, unlocking the trolley. However, in practice, the manual handling required for docking the trolley with the winding device results in low automation and fails to meet the needs of intelligent logistics for the trolley. In cases of human error, the locked state can lead to a large accumulation of semi-finished products on the winding trolley, hindering normal production. Furthermore, existing winding devices lack a function that links with the locking mechanism of the winding trolley, preventing automatic unlocking of the trolley when docked with the winding device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic unlocking material winding trolley that can automatically unlock without manual intervention when docked with a winding device. In addition, this utility model also provides a winding device that is used in conjunction with the aforementioned automatic unlocking material winding trolley to achieve a linkage unlocking function.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An automatic unlocking material winding trolley includes a frame, a large I-beam wheel, a small I-beam wheel, a guide roller, and a locking mechanism. The large and small I-beam wheels are fixed on the frame. The locking mechanism is located in the lateral space formed by the large and small I-beam wheels and the frame. The locking mechanism includes a handle, a connecting rod, a swing arm, and a tension spring. The handle is hinged to the frame via a pin. One end of the connecting rod is hinged to the handle, and the other end is hinged to the swing arm. The swing arm is hinged to a support fixed on the frame. A first brake roller and a second brake roller are provided in the direction extending from the swing arm towards the small I-beam wheel. The first and second brake rollers are located below the large and small I-beam wheels, respectively. One end of the tension spring is connected to a fixed seat fixed on the frame, and the other end is connected to the swing arm.

[0006] Furthermore, the connection point between the tension spring and the swing arm is located between the first brake roller and the second brake roller.

[0007] Furthermore, the length of the connecting rod can be adjusted.

[0008] Furthermore, a rotatable roller is provided in the direction in which the swing arm extends toward the large I-beam wheel.

[0009] Furthermore, both the first brake roller and the second brake roller are grooved rubber rollers.

[0010] Furthermore, a limit seat for the handle is provided on the frame.

[0011] A winding device, used in the aforementioned automatic unlocking winding material trolley, includes a winding fixing frame, a drive device connected to a large I-beam wheel, a braking device connected to a small I-beam wheel, and a conveying device for conveying the automatic unlocking winding material trolley, characterized in that: a triggering device is provided on the conveying device to drive the swing arm to lift.

[0012] Furthermore, the triggering device includes a cylinder and a wedge block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The automatic unlocking material winding trolley provided by this utility model can automatically unlock without manual intervention when docking with the winding device, which is conducive to achieving automated management and meeting the needs of intelligent logistics for material trolleys.

[0015] 2. The automatic unlocking material winding trolley provided by this utility model uses a tension spring-driven brake roller to apply force to the edge of the I-beam wheel to achieve the locking function. Compared with the existing technology that uses a compression spring to push a friction plate to apply force to the I-beam wheel coupling to achieve the locking function, since the diameter of the I-beam wheel is much larger than the diameter of the I-beam wheel coupling, the braking arm of the locking mechanism of this utility model is longer, and the locking effect is better.

[0016] 3. The winding device provided by this utility model has the function of being linked with the locking mechanism of the automatic unlocking winding material trolley. When the material trolley is docked with the winding device, the automatic unlocking function of the material trolley can be realized. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] The automatic unlocking material winding trolley provided by this utility model, such as Figures 1 to 4As shown, it includes a frame 3, a large I-beam wheel 1, a small I-beam wheel 2, a guide roller 4, and a locking mechanism 5. The large I-beam wheel 1 and the small I-beam wheel 2 are fixed on the frame 3. The locking mechanism 5 is located in the side space formed by the large I-beam wheel 1, the small I-beam wheel 2, and the frame 3. The locking mechanism 5 includes a handle 51, a connecting rod 52, a swing arm 53, and a tension spring 54. The handle 51 is hinged to the frame 3 via a pin 56. One end of the connecting rod 52 is hinged to the handle 51, and the other end is hinged to the swing arm 53. The swing arm 53 is hinged to a support 533 fixed on the frame 3. A first brake roller 531 and a second brake roller 532 are provided in the direction of the swing arm 53 extending towards the small I-beam wheel 2. The first brake roller 531 and the second brake roller 532 are respectively located below the large I-beam wheel 1 and the small I-beam wheel 2. One end of the tension spring 54 is connected to a fixed seat 55 fixed on the frame 3, and the other end is connected to the swing arm 53.

[0027] In the above implementation plan, such as Figure 4 As shown, when the material trolley is in the transfer or storage state, the swing arm 53 in the locking mechanism 5 is in a horizontal state under the tension of the tension spring 54. At this time, the first brake roller 531 and the second brake roller 532 press against the lower edges of the large I-beam 1 and the small I-beam 2 respectively, realizing the automatic locking function when the material trolley is in the transfer or storage state; Figure 3 As shown, after the material trolley is placed on the winding device, the trigger device 9 on the winding device (which can be any device that can drive the swing arm 53 to lift) can be used to drive the swing arm 53 to lift, thereby creating a gap between the first brake roller 531 and the second brake roller 532 and the lower edge of the large I-beam 1 and the small I-beam 2 respectively. This realizes the automatic unlocking function when the material trolley is docked with the winding device, without the need for manual intervention, which is conducive to realizing automated management and meeting the needs of intelligent logistics for material trolleys.

[0028] In the above implementation plan, such as Figure 4 As shown, when the locking mechanism 5 is in the locked state, the swing arm 53 in the locking mechanism 5 is pulled by the tension spring 54, and the first brake roller 531 and the second brake roller 532 apply force to the lower edges of the large I-beam 1 and the small I-beam 2 respectively to achieve locking. Compared with the existing technology that uses a compression spring to push the friction plate to apply force to the I-beam coupling to achieve the locking function, since the diameter of the I-beam is much larger than the diameter of the I-beam coupling, the braking arm of the locking mechanism 5 of this utility model is longer and the locking effect is better.

[0029] In the above implementation plan, such as Figure 3 and Figure 4As shown, when the material trolley docks with the winding device, as mentioned earlier, the locking mechanism 5 can be unlocked by driving the swing arm 53 to lift. In other situations requiring automatic unlocking, the locking mechanism 5 can also be automatically unlocked by any other triggering device capable of automatically driving the swing arm 53 to lift. Additionally, in situations requiring manual temporary unlocking, the handle 51 can be moved clockwise to create gaps between the first brake roller 531 and the second brake roller 532 and the lower edges of the large I-beam 1 and the small I-beam 2, respectively, thus enabling manual unlocking of the locking mechanism 5. Similarly, in situations requiring manual temporary locking, the handle 51 can be moved counterclockwise to press the first brake roller 531 and the second brake roller 532 against the lower edges of the large I-beam 1 and the small I-beam 2, thus enabling manual locking of the locking mechanism 5. Compared with existing technologies, the automatically unlocking winding material trolley provided by this utility model can meet the needs of various situations and has a wider range of applications.

[0030] In another embodiment of this utility model, such as Figures 1 to 4 As shown, in order to more effectively convert the tension of the tension spring 54 into the braking force of the first brake roller 531 on the large I-beam wheel 1 and the braking force of the second brake roller 532 on the small I-beam wheel 2, the position where the tension spring 54 is connected to the swing arm 53 is set between the first brake roller 531 and the second brake roller 532.

[0031] In another embodiment of this utility model, such as Figures 1 to 4 As shown, to achieve a better locking effect, the braking force of the first brake roller 531 on the large I-beam wheel 1 and the braking force of the second brake roller 532 on the small I-beam wheel 2 can be adjusted by adjusting the length of the connecting rod 52. The connecting rod 52 may include an adjusting nut, a positive thread screw, and a negative thread screw. One end of the adjusting nut is connected to the positive thread screw, and the other end is connected to the negative thread screw. The positive thread screw and the negative thread screw are respectively hinged to the handle 51 and the rocker arm 53. The length of the connecting rod 52 can be adjusted by adjusting the screwing length of the adjusting nut with the positive thread screw and the negative thread screw.

[0032] In another embodiment of this utility model, such as Figures 1 to 4 As shown, when the locking mechanism 5 switches from the locked state to the unlocked state, in order to facilitate the triggering device 9 to be inserted into the bottom of the swing arm 53 from the direction of the large I-beam wheel 1 to drive the swing arm 53 to lift, a rotatable roller 534 is provided in the direction of the swing arm 53 extending toward the large I-beam wheel 1.

[0033] In another embodiment of the present invention, in order to increase the friction between the brake roller and the I-beam, both the first brake roller 531 and the second brake roller 532 are rubber rollers with grooves.

[0034] In another embodiment of this utility model, such as Figures 2 to 4As shown, in order to limit the position of the locking mechanism 5 in the unlocked state, a limit seat 57 for the handle 51 is provided on the frame 3.

[0035] The winding device provided by this utility model is used in the aforementioned automatic unlocking winding material trolley, such as... Figure 5 As shown, it includes a winding and fixing frame 10, a drive device 6 connected to the large I-beam spool 1, a braking device 7 connected to the small I-beam spool 2, and a conveying device 8 for conveying the automatically unlocking winding material trolley. The conveying device 8 is equipped with a triggering device 9 that drives the swing arm 53 to lift. Preferably, as shown... Figure 6 , Figure 7 As shown, the triggering device 9 includes a cylinder 91 and a wedge block 92. The cylinder 91 is fixed next to the conveying device 8. When the automatically unlocking material winding trolley enters the winding device, the control system drives the cylinder 91, which in turn drives the wedge block 92 to insert below the swing arm 53, causing the swing arm 53 to lift, thereby unlocking the locking mechanism 5. In this embodiment, the winding device, through the triggering device 9, enables the winding device and the locking mechanism 5 of the automatically unlocking material winding trolley to have a mutual linkage function. When the material trolley docks with the winding device, the automatic unlocking function of the material trolley can be realized.
