Description

Technical Field

[0001] This application relates to the technical field of mechanical braking, and in particular to a pressure-out flap type pneumatic brake. Background Technology

[0002] In the field of extrusion production, with the continuous expansion of industrial production scale and the constant improvement of production efficiency requirements, higher demands are being placed on the performance and flexibility of various equipment on the production line. The coiling carriage plays a crucial role in the production line, undertaking important tasks such as material coiling. Its smooth entry and exit, as well as the effective braking of the chuck, are vital to the continuity and stability of production. At the same time, the development of automation and efficiency in production lines is prompting people to continuously seek more rational and reliable equipment structures and operating methods.

[0003] In the production process of related technologies, various methods are typically used to brake the chuck of the winding carriage and ensure its normal entry and exit. One common method is to install a fixed braking device, which is directly mounted at a specific location on the production line and brakes the chuck through mechanical locking or electromagnetic adsorption. In other cases, complex tracks and guide devices are used to guide the winding carriage in and out of specific areas, while braking devices are installed at appropriate locations to brake the chuck. These methods, to a certain extent, meet the basic production requirements.

[0004] However, these existing technologies have significant drawbacks. Fixed-position braking devices cannot move with the drive gear support, cannot adapt well to the forward and backward movements of the drive gear support in the production line, and can easily obstruct the entry and exit of the winding trolley, affecting production efficiency. Complex tracks and guiding devices not only increase equipment cost and maintenance difficulty, but their relatively fixed structure also lacks flexibility. Utility Model Content

[0005] To overcome the above-mentioned technical problems, this application provides a pressure-out flap type pneumatic brake.

[0006] The technical solution of the pressure-out flap type pneumatic brake provided in this application is as follows: A flip-plate type pneumatic brake for an extrusion line includes a base fixed to the original drive gear bracket of the extrusion production line. The base is connected to a braking mechanism driven by a flipping mechanism. The braking mechanism has a disc assembly adapted to the chuck of a coiling carriage. When the braking mechanism is not in operation, it is driven by the flipping mechanism to rotate to a non-obstructing angle with the coiling carriage station.

[0007] By adopting the above technical solution, the device is fixed on the drive gear bracket and can move forward and backward with the drive gear bracket; adopting a flip-plate structure, when not in operation, the braking mechanism rotates to a non-obstructing angle with the curling carriage station, so as not to obstruct the curling carriage from entering or exiting.

[0008] Optionally, the braking mechanism includes a connecting plate and a brake connected to the output end of the flipping mechanism. The brake is fixedly connected to the connecting plate, and the disc assembly is connected to the brake via a connecting shaft.

[0009] By adopting the above technical solution, the brake drives the disc assembly through the connecting shaft. The disc assembly, in cooperation with the chuck of the winding carriage, stops the moving parts of the winding carriage, increases resistance, or slows down the movement, thereby enabling the winding carriage to achieve the purpose of tightening the padding cloth.

[0010] Optionally, the disc assembly includes a disc and a plurality of chucks and chucks disposed on its end face, the chucks and chucks being adapted to the locking holes of the chuck of the winding carriage.

[0011] By adopting the above technical solution, the chuck and locking hole work together to ensure stable and reliable braking, while simplifying the structure and reducing maintenance costs. The flip-plate design ensures that the device does not interfere with the production process when not in operation. Optionally, the chuck shaft is at least partially located inside the disk, and a compression spring is provided inside the disk. One end of the compression spring is fixedly connected to the disk, and the other end is fixedly connected to the chuck shaft.

[0012] By adopting the above technical solution, the compression spring facilitates the extension and retraction of the chuck shaft. When the braking mechanism is in the working position and the chuck shaft is blocked by the chuck and fails to engage with the chuck's locking hole, the compression spring is compressed, and the chuck shaft retracts. As the chuck of the winding carriage rotates, when the chuck shaft encounters the chuck's locking hole, it automatically extends under the action of the compression spring and engages with the chuck's locking hole.

[0013] Optionally, the flipping mechanism includes a pusher, a rotating shaft, and a flip plate. The rotating shaft is rotatably connected to the base around its own axis. One end of the flip plate is fixedly connected to the rotating shaft, and the other end is fixedly connected to the connecting plate. A slider is provided at the output end of the pusher, and the slider is hinged to the flip plate through a hinge rod.

[0014] By adopting the above technical solution, the pusher drives the slider to move, which in turn drives the flip plate to rotate around the shaft, thereby realizing the flipping of the braking mechanism and ensuring that it can flexibly switch between working and non-working states, thus improving the practicality and ease of operation of the device.

[0015] Optionally, the pushing component is a cylinder, the piston rod of the cylinder is connected to the slider, the cylinder is fixed to the base, and the base is provided with a slide rail that cooperates with the slider.

[0016] By adopting the above technical solution, the cylinder pushes the slider to move precisely along the slide rail, driving the flip plate to rotate, realizing flexible switching of the braking mechanism, ensuring that the device is stable and reliable under different conditions, and the cylinder can provide stable thrust, so that the braking effect will not be affected by the insufficient thrust of the pushing component, further improving the stability and durability of the device.

[0017] Optionally, the base is provided with a limiting groove, which cooperates with the connecting seat to limit the maximum angle of the connecting seat's rotation stroke.

[0018] By adopting the above technical solution, the limiting groove effectively controls the rotation range of the connecting seat, avoids excessive rotation that could damage the mechanism, and ensures the stability and safety of the device during long-term use.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. The device is fixed on the drive gear bracket and can move forward and backward with the drive gear bracket to adapt to the movement of the drive gear bracket in the production line; 2. It adopts a flip-plate structure. When the braking mechanism is not in operation, it rotates to a non-obstructing angle with the curling trolley station, so as not to obstruct the curling trolley from entering or exiting. 3. The disc assembly is equipped with a compression spring, which facilitates the extension and retraction of the chuck shaft and allows for accurate engagement with the chuck locking hole during chuck rotation.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0024] This application discloses a pressure-out flap type pneumatic brake.

[0025] like Figure 1 As shown, the extrusion line flip-plate pneumatic brake includes a base 1 fixed on the original drive gear bracket of the extrusion line. The base 1 is connected to a braking mechanism driven by a flipping mechanism. The braking mechanism has a disc assembly adapted to the chuck of the coiling carriage. When the braking mechanism is not in operation, it is driven by the flipping mechanism to rotate to a non-blocking angle with the coiling carriage station.

[0026] The extrusion line flap-type pneumatic brake is fixed to the drive gear bracket and can move forward and backward with the drive gear bracket; it adopts a flap-type structure, and when not in operation, the braking mechanism rotates to a non-obstructing angle with the curling carriage station, so as not to obstruct the curling carriage from entering or exiting.

[0027] like Figure 1 As shown, the braking mechanism includes a connecting plate 3 connected to the output end of the tilting mechanism and a brake 2. The brake 2 is fixedly connected to the connecting plate 3, and the disc assembly is connected to the brake 2 via a connecting shaft 6. The brake 2 drives the disc assembly via the connecting shaft 6. The disc assembly, through its cooperation with the chuck of the curling carriage, stops, increases resistance, or decelerates the moving parts of the curling carriage, thereby enabling the curling carriage to achieve the purpose of tightening the padding cloth.

[0028] Specifically, the disc assembly includes a disc 4 and a plurality of chucks and chucks 5 disposed on its end face. The chucks and chucks 5 are adapted to fit into the locking holes of the winding carriage chuck. In order to enable the disc assembly to cooperate more smoothly with the winding carriage chuck under the action of the flipping mechanism, the chucks and chucks 5 can be at least partially located inside the disc 4. A compression spring is provided inside the disc 4, with one end of the compression spring fixedly connected to the disc 4 and the other end fixedly connected to the chucks and chucks 5.

[0029] In actual use, the chuck shaft 5 in the disc assembly of the tilting mechanism extends under the action of the compression spring. When the tilting mechanism drives the braking mechanism to rotate to the working position, the position of the chuck shaft 5 may not be completely aligned with the locking hole of the chuck on the winding carriage. Therefore, the chuck shaft 5 is blocked by the chuck, and the compression spring compresses the chuck shaft 5 to retract, so that the surface of the disc 4 is in contact with the surface of the chuck. As the chuck of the winding carriage rotates, when the chuck shaft 5 encounters the chuck locking hole, it automatically extends under the action of the compression spring and engages with the locking hole of the chuck. This achieves the engagement between the disc assembly and the chuck of the winding carriage, ensuring the braking effect.

[0030] like Figure 1As shown, the base 1 is a U-shaped base 1, including two side plates 101 and a bottom plate 102. The side plate 101 away from the bottom plate 102 has an edge for connecting to the drive gear bracket. The flipping mechanism includes a pusher 7, a rotating shaft 9, and a flip plate 10. The side plates 101 away from each other have a bearing seat 8. The two ends of the rotating shaft 9 are rotatably connected to the bearing seat 8, so as to achieve a rotatable connection to the base 1 around its own axis. One end of the flip plate 10 is fixedly connected to the rotating shaft 9, and the other end is fixedly connected to the connecting plate 3. The pusher 7 is located on the side of the bottom plate 102 near the side plate 101. The output end of the pusher 7 has a slider 11, which is hinged to the flip plate 10 through a hinge rod 13. To ensure the cooperation effect, the pusher 7 is a cylinder, and the piston rod of the cylinder is connected to the slider 11. The bottom plate 102 also has a slide rail 12 that cooperates with the slider 11.

[0031] In actual use, the cylinder drives the slider 11 to move along the slide rail 12, causing the flip plate 10 to rotate around the rotating shaft 9, thereby realizing the flipping of the braking mechanism and ensuring its flexible switching between working and non-working states, improving the practicality and ease of operation of the device. When the braking mechanism is in the working position, the cylinder can provide a stable thrust, and the braking effect will not be affected by the insufficient thrust of the pushing component 7, further improving the stability and durability of the device.

[0032] Optionally, a limiting groove 1021 is provided at the base plate 102. The limiting groove 1021 cooperates with the connecting seat to limit the maximum angle of the connecting seat's rotation stroke. The limiting groove 1021 can effectively control the rotation range of the connecting seat, avoid excessive rotation that could damage the mechanism, and ensure the stability and safety of the device during long-term use.

[0033] The implementation principle of the extrusion line flap-type pneumatic brake in this embodiment is as follows: The entire extrusion line flap-type pneumatic brake is fixed on the drive gear bracket via the base 1, and can move forward and backward with it to adapt to the movement of the production line. The pusher 7 in the flipping mechanism moves, causing the slider 11 to slide on the slide rail 12, and the flap 10 rotates around the rotating shaft 9 via the hinge rod 13, thereby driving the braking mechanism to rotate. In the non-working state, the braking mechanism rotates to a non-obstructing angle with the coiling carriage station, without affecting the entry and exit of the coiling carriage. When it is necessary to cooperate with the coiling carriage at the coiling carriage station, the flipping mechanism rotates the braking mechanism to the working position. When the chuck shaft 5 is blocked by the chuck and fails to cooperate with the chuck's locking hole, the compression spring is compressed, and the chuck shaft 5 retracts. As the chuck of the coiling carriage rotates, when the chuck shaft 5 encounters the chuck locking hole, it automatically extends under the action of the compression spring and cooperates with the chuck's locking hole, thus laying the foundation for braking. Based on this, the brake 2 drives the disc assembly through the connecting shaft 6. The disc assembly, in cooperation with the chuck of the winding carriage, stops the moving parts of the winding carriage, increases resistance, or slows down the movement, thereby enabling the winding carriage to achieve the purpose of tightening the padding cloth.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
