Description

[0001] The utility model relates to the technical field of strip steel processing equipment, in particular to a synchronous adjustment mechanism for a brush roller of a strip steel brushing trough. Background Art

[0002] In the cold-rolled strip degreasing and cleaning unit, the brush washing tank can achieve uniform cleaning of the steel plate surface and effectively remove the oil stains adsorbed on the steel plate. The stability and horizontality of the brush roller during the lifting process play a key role in the cleaning quality of the strip surface and the stable operation of the unit.

[0003] At present, the brush roller lifting of the original brush washing tank is as follows Figure 6 As shown, the transmission side and the operating side are individually raised and lowered by independently arranged spiral elevators, which cannot guarantee the synchronization of the two ends of the brush roller and the horizontality of the brush roller. It is easy to cause the strip to deviate during the operation of the unit, and even cause the unit to break in severe cases.

[0023] Example

[0024] In the current traditional lifting and adjusting mechanism of the brush roller of the brush washing tank, the transmission side and the operating side of the brush roller are separately lifted and adjusted by independently set spiral elevators. During the adjustment process, the synchronization of the two ends of the brush roller and the horizontality of the brush roller cannot be guaranteed, which easily causes the strip to deviate during the operation of the unit, and even causes the problem of the unit breaking the strip in severe cases. We propose a synchronous adjustment mechanism, and the specific plan is as follows:

[0025] The present embodiment discloses a synchronous adjustment mechanism for the brush roller of a strip steel brushing trough, specifically comprising a connecting shaft 1, both ends of the connecting shaft 1 are integrally formed with end sections 2, and external gears 6 are fixed to the end sections 2 at both ends of the connecting shaft 1. In order to prevent the external gear 6 from detaching from the connecting shaft 1, a shaft end baffle 7 is provided in the middle of a shaft sleeve 601, and the shaft end baffle 7 is fixedly connected to the end section 2 by bolts 8. The shaft sleeve 601 is installed on the end section 2 through the shaft end baffle 7, and an internal gear 9 is meshed on the inner side of the end of the external gear 6; wherein the center positions of the internal gears 9 at both ends of the connecting shaft 1 are provided with key connection holes 901, and the internal gears 9 at both ends of the connecting shaft 1 are respectively key-connected with the extended shaft transmission shafts in the spiral lifting mechanism 10 installed on both sides of the brushing trough and on the operating side and the transmission side through the key connection holes 901, and the input shaft of the spiral lifting mechanism 10 on the transmission side is connected to the spiral lifting drive shaft. The driving motor 11 is connected to the driving motor 11, and the lifting drive motor of the bolt 8 adopts a variable frequency reduction motor. In the whole design scheme, two sets of spiral lifting mechanisms 10 originally designed independently are connected together, so that the lifting adjustment of the brush roller of the washing trough is changed from the traditional dual-drive independent adjustment design, so that the lifting adjustment of the brush roller can be synchronously driven by a set of driving motors. The spiral lifting mechanisms 10 on the transmission side and the driving side can be synchronously driven, so that the two sides of the brush roller can be synchronously lifted and adjusted, and the horizontality of the two sides of the brush roller can be ensured, which can not only effectively prevent the strip from running off and improve the brushing effect, but also improve the double-sided independent drive. Improved to a single-sided synchronous linkage drive, the lifting and lowering adjustment of the brush roller can be simpler, and the equipment cost can be saved. At the same time, the use of a variable frequency reduction motor can also improve the stability of the lifting and lowering adjustment drive, and realize the adjustment of the lifting speed of the brush roller.

[0026] The outer gear 6 includes a sleeve 601 sleeved on the outside of the end portion 2, and a gear sleeve 602 is integrally formed at the end of the sleeve 601. The inner gear 9 is located on the inner side of the gear sleeve 602 and meshes with the teeth on the inner side of the gear sleeve 602. A spring holder 3 is provided at the connection between the connecting shaft 1 and the end portion 2, and a compression spring 4 is sleeved on the outside of the end portion 2 and between the spring holder 3 and the sleeve 601. In the entire structural design, the transmission shaft and the inner gears 9 at both ends are transmitted through the plug-in meshing of the inner gear 9 and the outer gear 6, while the inner gear 9 is transmitted through a key connection with the shaft extending from the spiral lifting mechanism 10 on the corresponding side. The design of the compression spring 4 enables the outer gear 6 to always maintain sufficient thrust to the outside, ensuring that the outer gear 6 can always maintain effective transmission with the inner gear 9.

[0027] In order to realize the synchronous linkage of the spiral lifting mechanisms 10 on both sides, a key connection is adopted between the external gear 6 and the connecting shaft 1. Specifically, key grooves A201 are provided on the end parts 2 at both ends of the connecting shaft 1, and a key groove B603 is provided on the inner side of the sleeve 601 at a position corresponding to the key groove A201, and wedge blocks 5 are inserted into the key grooves A201 and B603. In this design, the connecting shaft 1 and the external gear 6 can achieve a certain degree of expansion and contraction while achieving a key connection, which helps to facilitate the disassembly and maintenance of the synchronous adjustment mechanism in the later stage with the help of the compression spring 4.
