Description

Technical Field

[0001] The utility model relates to the technical field of winders, in particular to a winding machine rotating shaft clamping brake mechanism. Background Art

[0002] Winding machine is one of the commonly used equipment in aluminum processing industry. It is mainly used to wind aluminum strip to facilitate storage and transportation of aluminum strip after coiling. At present, the shutdown of many winders relies on brake mechanisms. These brake mechanisms are usually divided into butterfly brakes and drum brakes. For example, the utility model patent with publication number CN201620088707.7, named a shaft-holding brake device, controls the brake pad according to the swing of the brake disc. When the brake pad contacts the rotating shaft, the brake is applied and the rotating shaft cannot rotate. When the brake pad does not contact the rotating shaft, the rotating shaft can rotate.

[0003] However, the above brake device is not suitable for the winder. After the winder winds up the aluminum strip, the load-bearing capacity of the shaft increases and the rotational inertia increases, making it difficult to brake quickly. A single braking cycle will inevitably become longer, increasing the wear on the brake device and increasing the cost of maintenance and replacement. Utility Model Content

[0004] The utility model aims to provide a winding machine rotating shaft clamping brake mechanism to solve the problem that a general brake device used for a winding machine will inevitably prolong a single braking cycle, increase wear, and increase maintenance and replacement costs.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A winding machine shaft clamping brake mechanism comprises a shaft, one end of which is provided with a clamping brake mechanism, the clamping brake mechanism comprising an eccentric shaft sleeve, an outer sleeve, a blocker and a telescopic rod, the eccentric shaft sleeve being mounted on the shaft, at least one of the telescopic rods being mounted on a fixed base, the outer sleeve being mounted on the output end of the telescopic rod, a plurality of blockers being mounted on the outer sleeve, and the inner ends of the blockers being matched with the eccentric shaft sleeve.

[0007] A further technical solution is: the telescopic rod is a cylinder.

[0008] A further technical solution is: the blocker includes a column, a spring, a pressure plate and a tightening rod, the column, the spring and the pressure plate are all slidably installed in the slide groove of the outer sleeve, the tightening rod is installed on the outer sleeve through a threaded structure, and the tightening rod is pressed against the pressure plate, the pressure plate is pressed against the spring, and the column is pressed against the spring.

[0009] A further technical solution is that the inner end of the column is hemispherical.

[0010] A further technical solution is: the eccentric sleeve is conical, and the smaller end is close to the telescopic rod.

[0011] A further technical solution is: one end of the rotating shaft is slidably connected to the outer sleeve.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] The utility model proposes a winding machine rotating shaft clamping brake mechanism, by which the traditional friction braking method can be changed into an obstruction-type braking method, even if the inertia of the rotating shaft is increased and the single braking time is prolonged, the clamping brake mechanism will not be excessively worn, thereby prolonging the service life of the clamping brake mechanism and ensuring the performance of use, and the braking force of the clamping brake mechanism is adjustable, which is convenient to use.

[0024] Embodiment 1:

[0025] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a winding machine shaft clamping brake mechanism includes a shaft 1, and a clamping brake mechanism 2 is arranged at one end of the shaft 1. The clamping brake mechanism 2 includes an eccentric sleeve 3, an outer sleeve 4, a blocker 5 and a telescopic rod 6. The eccentric sleeve 3 is installed on the shaft 1, at least one telescopic rod 6 is installed on a fixed base, the outer sleeve 4 is installed on the output end of the telescopic rod 6, and a plurality of blockers 5 are installed on the outer sleeve 4, and the inner end of the blocker 5 is adapted to the eccentric sleeve 3. The telescopic rod 6 is a cylinder. The blocker 5 includes a column 7, a spring 8, a pressure plate 9 and a tightening rod 10. The column 7, the spring 8 and the pressure plate 9 are all slidably installed in the slide groove of the outer sleeve 4. The tightening rod 10 is installed on the outer sleeve 4 through a threaded structure, and the tightening rod 10 presses against the pressure plate 9, the pressure plate 9 presses against the spring 8, and the column 7 is pressed against by the spring 8.

[0026] The telescopic rod 6 uses a cylinder to push the outer sleeve 4 to move and gradually approach the rotating shaft 1. During the movement, the blocker 5 will press against part of the surface of the eccentric sleeve 3 under the action of the spring 8, causing an obstacle to the rotating rotating shaft 1, thereby achieving the purpose of braking and stopping. The force applied by the spring 8 to the column 7 can be controlled by the tightening rod 10. In addition, the braking speed can also be controlled according to the degree of movement of the outer sleeve 4 toward the rotating shaft 1.

[0027] Preferably, the inner end of the column 7 is hemispherical.

[0028] The hemispherical shape prevents the column 7 from wearing the rotating shaft 1 .

[0029] Preferably, the eccentric sleeve 3 is conical, and the smaller end is close to the telescopic rod 6 .

[0030] The eccentric sleeve 3 is convenient to move in the outer sleeve 4 and is well pressed against the column 7 of the blocker 5 to reduce the occurrence of interference.

[0031] Preferably, one end of the rotating shaft 1 is slidably connected to the outer sleeve 4 .

[0032] When the outer sleeve 4 is moved, the rotating shaft 1 is used for guiding.

[0033] The working process of the utility model is as follows: when the rotating shaft 1 needs to stop rotating, the telescopic rod 6 can push the outer sleeve 4 to move forward in the direction of the rotating shaft 1. During this period, the column 7 of the blocker 5 will press against part of the surface of the eccentric sleeve 3, and the rotating shaft 1 will do work on the column 7 to consume energy, that is, the blocker 5 hinders the rotating rotating shaft 1, thereby achieving the purpose of braking and stopping.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
