AI Technical Summary
In existing dust collectors, the inversion of the motor and the shaft can easily cause the shaft to get stuck and lead to the breaking of the vibration shaft, especially in large dust collectors, which are more common to install errors.
An anti-reverse vibration and hammering device is designed, including a fixed bracket, bearing jacket, roller, bearing inner sleeve and vibration and hammering shaft. The roller ring is arranged on the outside of the bearing inner sleeve, and the groove gradually decreases in a clockwise or counterclockwise direction. Small, the roller is arranged in the groove, and the roller hardness is greater than that of the inner sleeve of the bearing to prevent the shaft from being stuck when reversed.
Effectively prevent breakage and damage of the shaft, coupling and vibration assembly, and prevent bearing damage caused by motor reversal through the roller jamming mechanism.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust collectors, in particular to the technical field of rapping devices. Background Art
[0002] The existing side vibration motor and shaft of the dust collector are directly connected through a coupling. The rotation direction of the motor can be forward or reverse depending on the wiring. Reversal can easily cause the shaft to get stuck. In large dust collectors, the shaft directions are often symmetrical, which can easily lead to installation errors. Motor wiring errors can cause the shaft to reverse. Due to the structure of the shaft, hammer assembly and vibration rod, the vibration shaft reverses, and the hammer assembly and vibration rod will get stuck, resulting in shaft breakage. Utility Model Content
[0003] The purpose of the utility model is to solve the problems in the prior art and to provide an anti-reverse vibration device for a dust collector, which can solve the above problems.
[0004] To achieve the above-mentioned purpose, the utility model proposes an anti-reverse rapping device for a dust collector, comprising a fixed bracket, a bearing outer sleeve, rollers, a bearing inner sleeve and a rapping shaft, the rapping shaft is connected to a rapping motor, the fixed bracket is fixed to the bearing outer sleeve, a plurality of rollers are arranged between the bearing outer sleeve and the bearing inner sleeve, the roller ring is arranged on the outer side of the bearing inner sleeve, the bearing inner sleeve is fixed to the rapping shaft, the outer side of the bearing inner sleeve is provided with grooves matching the number of rollers, the groove depth gradually decreases along the clockwise or counterclockwise direction, and the rollers are arranged in the grooves.
[0005] Preferably, the maximum depth of the groove is greater than the radius of the roller.
[0006] Preferably, the roller and the bearing inner sleeve are made of different materials, and the hardness of the roller is greater than the hardness of the bearing inner sleeve.
[0007] Preferably, the roller is made of No. 45 steel and the bearing inner sleeve is made of No. 20 steel.
[0008] Preferably, the bearing sleeve is made of No. 20 steel.
[0009] Preferably, the diameter of the roller is 8 mm.
[0010] Preferably, the lengths of the roller, the bearing inner sleeve and the bearing outer sleeve are all 50 mm.
[0011] The beneficial effects of the utility model are as follows: the utility model provides an anti-reverse rapping device on the rapping shaft. When the rapping shaft reverses, the round steel roller falls into the groove of the inner sleeve of the bearing and becomes stuck, causing the rapping motor to trip due to overcurrent, thereby preventing the rapping shaft, coupling and rapping components inside the electric field from breaking or being damaged.
[0012] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural schematic diagram of the utility model;
[0014] Figure 2 It is an installation schematic diagram of the utility model.
[0015] In the figure: 1-fixed bracket; 2-bearing outer sleeve; 3-roller; 4-bearing inner sleeve; 5-rapping shaft, 6-groove. DETAILED DESCRIPTION
[0016] See also Figure 1 , Figure 2 , a dust collector anti-reverse rapping device, comprising a fixed bracket 1, a bearing sleeve 2, a roller 3, a bearing inner sleeve 4 and a rapping shaft 5, the rapping shaft 5 is connected to a rapping motor, the fixed bracket 1 is fixed to the bearing sleeve 2, a plurality of rollers 3 are arranged between the bearing sleeve 2 and the bearing inner sleeve 4, the rollers 3 are arranged on the outside of the bearing inner sleeve 4, the bearing inner sleeve 4 is fixed to the rapping shaft 5, the outside of the bearing inner sleeve 4 is provided with grooves 6 matching the number of rollers 3, the depth of the groove 6 gradually decreases along the counterclockwise direction, the rollers 3 are arranged in the grooves 6, the maximum depth of the grooves 6 is greater than the radius of the rollers 3, the hardness of the rollers 3 is greater than the hardness of the bearing inner sleeve 4, the rollers 3 are made of 45# steel, the bearing inner sleeve 4 is made of 20# steel, the diameter of the rollers 3 is 8mm, and the lengths of the rollers 3, the bearing inner sleeve 4 and the bearing sleeve 2 are all 50mm.
[0017] Working process of this utility model:
[0018] During the operation of the utility model, when the motor rotates forward, the rapping shaft works normally; when the motor rotates reversely, the rapping shaft rotates clockwise, the round steel roller falls into the groove, the groove at the round steel roller becomes narrower, causing the roller to jam the inner sleeve of the bearing, causing the rapping motor to trip due to overcurrent, thereby preventing the rapping shaft, coupling and rapping components inside the electric field from breaking or being damaged.
[0019] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
