In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in fig. 1 to 3, the present embodiment provides a catch wheel mechanism 100 including a catch wheel 1, a moving part 2, a connecting part 3, and an elastic member 4.
Wherein, the wheel of catch wheel 1 is equipped with the ring channel 11 that can supply the conveying belt edge to stretch into on the wheel week, and catch wheel 1 rotates and installs on removal portion 2. One end of the connecting part 3 is connected with the moving part 2, and the other end of the connecting part 3 is used for being connected with a bracket 6 of the conveying belt 5.

When the conveying belt 5 deviates, the edge of the conveying belt 5 contacts with the bottom of the annular groove 11, and the friction force between the conveying belt 5 and the catch wheel 1 drives the catch wheel 1 to rotate. Along with the increase of the deviation degree of the conveying belt 5, the conveying belt 5 drives the moving part 2 to move towards the direction of the support 6 close to the conveying belt 5, and the elastic part 4 is compressed and provides elastic support for the moving part 2 in the moving process until the conveying belt 5 does not deviate towards the deviation direction. Along with the reduction of the load on the conveyer belt 5, the elastic piece 4 gradually extends and drives the moving part 2 to move, so that the conveyer belt 5 is reset or close to reset.
In order to avoid damage to the elastic member 4, the elastic member 4 in this embodiment provides only elastic force, and the connecting portion 3 receives a shearing force. In order to enable the moving part 2 to move towards and away from the support 6 of the conveyor belt 5, the connecting part 3 should be fixedly arranged at one end and slidably arranged at the other end. In this embodiment, one end of the connecting portion 3 is fixedly connected with the moving portion 2, specifically, fixedly connected in a threaded connection manner, and the other end of the connecting portion 3 is slidably connected with the bracket 6 of the conveyor belt 5. According to different actual requirements, a person skilled in the art can also choose to fixedly connect one end of the connecting part 3 with the bracket 6 of the conveyor belt 5, and the other end of the connecting part 3 is slidably connected with the moving part 2.
In order to limit the sliding process of the connecting portion 3, the connecting portion 3 includes a link 31 and a limiting portion 32 in this embodiment. The connecting rod 31 is used for penetrating through the bracket 6 of the conveying belt 5, one end of the connecting rod 31 is fixedly connected with the moving part 2, the other end of the connecting rod 31 is fixedly provided with a limiting part 32, and the limiting part 32 can be in limiting contact with the bracket 6 of the conveying belt 5 when the connecting rod 31 slides relative to the bracket 6 of the conveying belt 5. When the limiting part 32 is installed on one side of the bracket 6 of the conveyor belt 5 close to the moving part 2, the limiting part 32 can limit the minimum distance between the moving part 2 and the bracket 6 of the conveyor belt 5; when the stopper 32 is attached to the side of the bracket 6 of the conveyor belt 5 away from the moving part 2, the stopper 32 can limit the maximum distance between the moving part 2 and the bracket 6 of the conveyor belt 5.
In this embodiment, at least one stopper 32 is mounted on the side of the support 6 of the conveyor belt 5 remote from the moving part 2.
Further, in the present embodiment, the mounting position of the stopper portion 32 on the link 31 can be adjusted, and the elastic member 4 can be pre-compressed by shortening the distance between the stopper portion 32 and the moving portion 2, so that the elastic member 4 provides a large elastic force when the moving portion 2 initially moves.
This spacing portion 32 can be stop nut, and stop nut and connecting rod 31 threaded connection, and other types of spacing portion 32 also can be selected for use to the skilled person in the art, for example the spacer pin to make spacer pin and connecting rod 31 pin-hole cooperation, as long as the mounted position of spacing portion 32 on connecting rod 31 can be adjusted.
In this embodiment, the limiting portion 32 includes a screw 321, a fixing plate 322, a nut 323, and a bolt 324, the screw 321 is in threaded connection with the end of the connecting rod 31, the screw 321 passes through the fixing plate 322 and fixes the fixing plate 322 to the end of the connecting rod 31, the bolt 324 is in threaded connection with the fixing plate 322 and the nut 323 at the same time, the nut 323 is located on one side of the fixing plate 322 far away from the catch wheel 1, and the small end of the bolt 324 abuts against the bracket 6 of the conveyor belt 5. The position of the fixing plate 322, and thus the compression degree of the elastic member 4 and the position of the connecting rod 31, can be adjusted by rotating the bolt 324. After the bolt 324 is adjusted, the nut 323 is locked, so that the nut 323 is tightly pressed against the fixing plate 322, thereby preventing the bolt 324 from loosening.
In the present embodiment, the elastic member 4 is preferably a spring, and those skilled in the art can select other types of elastic members 4 such as a spring plate, as long as they can provide elastic force. In order to facilitate the installation of the spring, the spring is sleeved outside the connecting rod 31 in the embodiment, and two ends of the spring can respectively abut against the moving part 2 and the bracket 6 of the conveying belt 5. Other mounting means of the spring can be chosen by the skilled person according to the actual need, for example, both ends of the spring are welded to the moving part 2 and the bracket 6 of the conveyor belt 5, respectively.
The moving part 2 may be a single member or a combination of a plurality of members. In this embodiment, the moving part 2 includes a first moving part 21 and a second moving part 22, the catch wheel 1 is rotatably mounted on the first moving part 21, one end of the connecting part 3 is connected to the second moving part 22, and the first moving part 21 is connected to the second moving part 22.
The first moving portion 21 and the second moving portion 22 may be rotationally connected, and if there are a plurality of blocking wheels 1, the blocking wheels 1 should be distributed on two sides of the relative rotation axis of the first moving portion 21 and the second moving portion 22 (as in the distribution mode of two blocking wheels 1 on the left side in fig. 2), and the conveyor belt 5 may limit the blocking wheels 1 on each moving portion 2, so that the first moving portion 21 can only rotate at a small angle; in this case, if there is one catch wheel 1, the rotation axis of the catch wheel 1 and the relative rotation axes of the first moving part 21 and the second moving part 22 should be collinear.
