[0021] Attached Figure 1 It is the structural diagram of the conveyor line clamp adjustment device;

[0022] Attached Figure 2 A top view of the conveyor line clamp adjustment device. DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] As attached Figure 1 With attached Figure 2 The conveyor line fixture adjustment device shown includes a frame 1, a power element 2, a center wheel 3, a planetary shaft 4, a first planetary wheel 5, a second planetary wheel 6, a first output wheel 7, a first connecting shaft 8, a second output wheel 9 and a second connecting shaft 10. The connection relationship between the various parts will be specifically introduced below:

[0025] The frame 1 is fixedly arranged; the power element 2 is used to provide power; the center wheel 3 is rotatably installed relative to the frame 1, and the center wheel 3 is drivingly connected to the power element 2; the planetary shaft 4 is rotatably installed on the center wheel 3; the first planetary wheel 5 is fixedly installed on the planetary shaft 4, and the first planetary wheel 5 is located on one side of the center wheel 3; the number of teeth of the second planetary wheel 6 is different from that of the first planetary wheel 5, and it is fixedly installed on the planetary shaft 4, and it is located on the other side of the center wheel 3; the first output wheel 7 is meshed with the first planetary wheel 5, and the first output wheel 7 is meshed with the center wheel 3 Concentrically installed; the first connecting shaft 8 is drivingly connected to the first output wheel 7, and it is connected to the first conveying chain assembly 15, and a plurality of clamping members 17 are arranged in an array on the chain of the first conveying chain assembly 15; the second output wheel 9 is meshed with the second planetary wheel 6, and it is concentrically installed with the center wheel 3; the second connecting shaft 10 is drivingly connected to the second output wheel 9, and it is connected to the second conveying chain assembly 16, and a plurality of clamping members 17 are arranged in an array on the chain of the second conveying chain assembly 16, and the number of clamping members 17 on the first conveying chain assembly 15 is equal to the number of clamping members 17 on the second conveying chain assembly 16. Each clamping member 17 on the first conveying chain assembly 15 and a clamping member 17 on the second conveying chain assembly 16 form a set of clamps.

[0026] The center wheel 3, the planetary shaft 4, the first planetary wheel 5 and the first output wheel 7 constitute a first planetary gear train connected to the first connecting shaft 8, and the center wheel 3, the planetary shaft 4, the second planetary wheel 6 and the second output wheel 9 constitute a second planetary gear train connected to the second connecting shaft 10. The transmission ratio between the first planetary wheel 5 and the first output wheel 7 is the first transmission ratio, and the transmission ratio between the second planetary wheel 6 and the second output wheel 9 is the second transmission ratio, and the first transmission ratio and the second transmission ratio are reciprocal to each other. In this way, when the center wheel 3 does not rotate, the rotation speeds of the first output wheel 7 and the second output wheel 9 are equal, and the rotation speeds of the first transmission chain assembly 15 and the second transmission chain assembly 16, which have a transmission relationship with the two, are equal. When the center wheel 3 rotates, since the angular velocity of revolution and the angular velocity of rotation of the first planetary wheel 5 and the second planetary wheel 6 are the same, and the number of teeth of the two is different, the rotation speeds of the first output wheel 7 and the second output wheel 9 are different, and a differential speed is formed between the two. In this way, the rotation speeds of the first transmission chain assembly 15 and the second transmission chain assembly 16 are different, and the spacing between the two clamping members 17 of the clamp will change, so as to achieve the purpose of adjusting the clamp. The value of the output displacement of the control element 2 can accurately adjust the spacing between the two clamping members 17 of the clamp, so that the adjustment is accurate. In this embodiment, the power element 2 is a motor, preferably a servo motor that can accurately control the rotation angle.

[0027] Optionally, the center wheel 3 is a worm wheel, and the power element 2 establishes a driving relationship with the center wheel 3 through a worm 11 used in conjunction with the center wheel 3. Since the worm gear mechanism has a self-locking effect, when the power element 2 is not running, the center wheel 3 cannot rotate, so that the conveyor line can be transported stably.

[0028] The second connecting shaft 10 is arranged in parallel with the first connecting shaft 8; the second planetary gear 6 is rotatably mounted on the frame 1 through the second output wheel 9 and the third connecting shaft 12, and a first transmission assembly 13 is arranged between the third connecting shaft 12 and the first connecting shaft 8 to establish a transmission relationship between the two, and a second transmission assembly 14 is arranged between the second connecting shaft 10 and the first connecting shaft 8 to establish a transmission relationship between the two. In this embodiment, both the first transmission assembly 13 and the second transmission assembly 14 are gear sets. Among them, the speed ratio of the first transmission assembly 13 is the third transmission ratio, and the speed ratio of the second transmission assembly 14 is the fourth transmission ratio, and the third transmission ratio and the fourth transmission ratio are reciprocal to each other, so that when the center wheel 3 does not rotate, the rotation speeds of the first conveying chain assembly 15 and the second conveying chain assembly 16 are equal, the conveying line performs the conveying operation normally, and the spacing between the two clamping members 17 of the clamp does not change.

[0029] Preferably, in order to ensure smooth operation of the mechanism, there are three planetary shafts 4, all of which are installed in a circular array on the power element 2, and each planetary shaft 4 is correspondingly installed with one first planetary gear 5 and one second planetary gear 6.

[0030] In addition, in this embodiment, there are two sets of the first conveying chain components 15 and the second conveying chain components 16 , and the clamps on the two sets of conveying chain components clamp the two sides of the material to be transported respectively.

[0031] The conveyor line clamp adjustment device of the present invention can achieve the purpose of adjusting the clamp by operating the power element to drive the center wheel to rotate so as to produce a differential between the first conveyor chain assembly and the second conveyor chain assembly, so that the clamp can be adjusted to adapt to changes in the object to be conveyed without manual adjustment. The adjustment process is risk-free and convenient with high adjustment accuracy.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
