The shafts of the fixing base 101, the driving wheel 401 and the driving wheel 300 are not in contact with each other, and when the driving wheel 401 and the driving wheel 300 rotate, the fixing base 101 does not affect the rotation of the driving wheel 401 and the driving wheel 300.

In this embodiment, the fixing plate 101 may be provided as a telescopic structure, and both ends of the fixing plate are sleeved on the shafts of the driving wheel 401 and the driving wheel 300, so that the telescopic structure can be applied to different conveying belts. The driving member 300 drives the movable unit 200 to move on the fixed unit 100, wherein the bells 103 are installed at four corners of the movable groove 102, and the movable member 202 collides with the bells 103 when moving in the movable groove 102, i.e. a signal that the belt slips is generated.

Example 2

Referring to fig. 3 and 4, a second embodiment of the present invention is based on the previous embodiment, which differs from the previous embodiment in that: the movable unit 200 further includes a telescopic component 201 and a movable component 202 connected to each other.

Specifically, the whole movable groove 102 is a rectangular groove, the direction of the whole movable groove 102 is consistent with that of the fixed seat 101, the movable groove 102 is arranged in the middle of the fixed seat 101, the movable groove 102 comprises a first sliding groove 102a located in the middle and second sliding grooves 102b arranged on two sides of the first sliding groove 102a, first movable holes 102a-1 are formed in two ends of the first sliding groove 102a, and second movable holes 102a-2 are formed in the middle of the connecting portion of the second sliding groove 102b and the first sliding groove 102 a. Wherein, the first movable hole 102a-1 is a circular hole, and the second movable hole 102a-2 is a longer hole.

Further, the telescopic assembly 201 comprises a transmission member 201a, a telescopic member 201b and an elastic member 201c, the transmission member 201a is a circular wheel as a whole, the edge of the wheel is smooth and is provided with an arc-shaped notch 201a-1, two transmission members 201a are provided, and the two transmission members 201a are respectively installed on the shafts of the driving wheel 401 and the driving wheel 300. The middle of the telescopic piece 201b is a round rod, one end of the round rod is provided with a round head 201b-1, the surface of the round head 201b-1 is smooth and is attached to the edge surface of the transmission piece 201a, the other end of the round rod is provided with a limiting ring 201b-2, the telescopic piece 201b penetrates through the first movable hole 102a-1, and the limiting ring 201b-2 is located in the first movable hole 102 a-1. The telescopic member 201b can slide in the radial direction in the first movable hole 102 a-1.

Still further, the middle of the movable member 202 is provided with a movable block 202a, the movable block 202a is disposed in the first sliding groove 102a, and the elastic member 201c is disposed between the movable block 202a and the limiting ring 201 b-2. The fixed plates 202b are arranged on two sides of the movable block 202a, the fixed plates 202b are located in the second sliding groove 102b, the movable block 202a and the fixed plates 202b are connected through a smooth connecting rod 202a-1, the smooth connecting rod 202a-1 penetrates through the second movable hole 102a-2, and when the movable block 202a slides in the first sliding groove 102a, the fixed plates 202b are driven to slide together. The elastic member 201c is a compression spring, and two ends of the spring respectively abut against the limiting ring 201b-2 and the movable block 202 a.

Further, a plurality of rollers 202c are mounted on the fixed plate 202b, and the rollers 202c roll in the second sliding groove 102 b. Hammers 202d are provided at both ends of the fixing plate 202b, the bell 103 is mounted at both ends of the second slide groove 102b, and the hammers 202d collide with the bell 103. Under the action of the roller 202c, the fixed plate 202b can move more easily, and the movable member 202 is not displaced as a whole.

In this embodiment, there are two transmission members 201a, two telescopic members 201b, and two elastic members 201c, and the two transmission members 201a are respectively mounted on the shafts of the driving wheel 401 and the driving wheel 300, and the driving wheel 401 and the driving wheel 300 rotate in opposite directions under the action of the belt. The two transmission members 201a are identical, and when the two transmission members 201a are installed, the arc-shaped recesses 201a-1 of the two transmission members 201a are oppositely arranged, that is, when the arc-shaped recess 201a-1 of one transmission member 201a faces the movable groove 102, the arc-shaped recess 201a-1 of the other transmission member 201a also faces the movable groove 102. Because the rotating speeds of the driving wheel 401 and the driving wheel 300 are the same, when one transmission piece 201a rotates for one circle, the other transmission piece 201a also rotates for one circle, when the belt normally runs, the telescopic piece 201b abuts against the edge of the transmission piece 201a, the two transmission pieces 201a synchronously rotate, the telescopic piece 201b synchronously moves into or slides out of the arc-shaped notch 201a-1 under the action of the elastic piece 201c, at the moment, the forces applied to the two ends of the movable block 202a are consistent, and the movable block cannot greatly shake; when the belt slips, the rotation speeds of the driving wheel 401 and the driving wheel 300 are different, the rotation of the two transmission members 201a is not synchronous any more, when the telescopic member 201b at one end enters the arc-shaped recess 201a-1, the telescopic member 201b at the other end abuts against other positions on the edge of the transmission member 201a, at this time, the stress at the two ends of the movable block 202a is different under the action of the spring, the movable block 202a slides back and forth in the first sliding groove 102a, and the hammer 202d in the second sliding groove 102b continuously impacts the bells 103 at the two ends, so that the belt slip is warned.

The belt slip detection device disclosed by the invention adopts a pure mechanical structure, can work in a severe environment with high humidity and much dust, avoids the problems of difficulty in adjusting a delay function and the like caused by adopting a magnetoelectric device, can timely detect whether the belt slips and sends out an alarm sound by generating corresponding actions through linkage with the belt.
