Seats 38 are threadedly connected with the first screw rod 35 and the second screw rod 36 respectively, and are used for relative movement or relative movement along the first direction, and the driving member 31 is drivingly connected with the rotating shaft 33, and the rotating shaft 33, the first screw rod 35 and the second screw rod 36 are respectively connected with the first reversing assembly 34, and the first reversing assembly 34 is used to drive the first screw rod 35 and the second screw rod 36 to reversely rotate through the rotational power of the rotating shaft 33.

Specifically, the drive member 31 is usually a servo motor, the rotating shaft 33 is arranged on the base 1 along the front-rear direction, and the first screw 35 and the second screw 36 are arranged on the base 1 along the left-right direction.

The connecting seat 37 and the second connecting seat 38, at the same time, two supporting points are also arranged in the front and rear direction, that is, two first connecting seats 37 in the front and rear direction and two second connecting seats 38 in the front and rear direction, that is, That is to say, a rotating shaft 33 , a first reversing assembly 34 , a first screw 35 and a second screw 36 are provided on both sides of the second reversing assembly 32 in the second direction. The driving member 31 is fixed on the base 1 with the motor shaft arranged horizontally (ie, the motor shaft is arranged along the first direction), and the second reversing assembly 32 is arranged between the driving member 31 and the two rotating shafts 33 .

In this way, during the adjustment process of the adjustment mechanism 3, the rotational power output by the driving member 31 is reversed by the second reversing assembly 32 and transmitted to the two rotating shafts 33 respectively, so as to simultaneously drive the two rotating shafts 33 to rotate in reverse, and then After the two rotating shafts 33 are commutated by the corresponding second reversing assembly 34, they are transmitted to the corresponding first screw 35 and second screw 36 respectively, so as to simultaneously drive the corresponding first screw 35 and second screw 36 to reverse Rotate, and then drive the corresponding first connecting seat 37 and the second connecting seat 38 to move relative to each other or towards each other, so that one driver 31 can be used to simultaneously drive two groups of first screw rods 35 and second screw rods 36 to reverse direction at the same time The rotation not only has a simple structure, but also further reduces the production cost.

In this way, when the first chain plate 21 and the second chain plate 22 move relative to each other or move towards each other, the first slider 13 and the second slider 14 can be used to slide along the slide rail 12 to realize the guidance, so as to ensure that the first chain plate 21 and the second chain plate 22 move along the preset first direction, and the first slider 13 and the second slider 14 can also serve as support points to provide support for the chain plate assembly 2, so as to share the first connection Seat 37 and the load of the second connection seat 38.

In this way, the adjusting mechanism 3 can be protected by the seat body 11 , and at the same time, the overall volume of the adjusting mechanism 3 and even the chain conveyor can be reduced.

Optionally, as shown in FIG. 5 , the lifting mechanism 4 includes a telescopic assembly 41 and a guide assembly 42, one end of the telescopic assembly 41 and the guide assembly 42 are respectively connected to the first translation mechanism 5, and the other end of the telescopic assembly 41 and the guide assembly 42 One end is connected to the base 1 respectively, and the telescopic assembly 41 is used for telescopically extending and contracting in the vertical direction.

Specifically, the telescopic assembly 41 may be a hydraulic cylinder assembly, may also be an electric cylinder assembly, and may also be a mechanical structure such as a scissor mechanism that realizes lifting through telescopic movement. There are usually multiple guide assemblies 42 , and the multiple guide assemblies 42 are arranged around the telescopic assembly 41 . One end of the telescopic assembly 41 and the guide assembly 42 are respectively connected to the first support plate 53 (described later) of the first translation mechanism 5, and the other ends of the telescopic assembly 41 and the guide assembly 42 are respectively connected to the base 1 or the second translation mechanism 7 (introduced later).

In this embodiment, the telescopic movement of the telescopic assembly 41 is used to drive the base 1 to move up and down to realize the lifting of the chain plate assembly 2. The structure is simple and easy to realize. At the same time, the lifting movement is guided by setting the guide assembly 42 to prevent The base 1 and the chain plate assembly 2 tilt during the lifting process.

In this way, the guide post 421 and the guide sleeve 422 that are slidingly connected to realize the guide have a simple structure and are easy to implement.

Optionally, as shown in FIG. 6 , the first translation mechanism 5 includes a first power component 51, a first rotation-to-translation assembly 52 and a first support plate 53, the lifting mechanism 4 is connected to the first support plate 53, and the first support The plate 53 is connected with the translation structure of the first rotation-to-translation assembly 52 or the first power part 51, and the first power part 51 is drivingly connected with the rotation structure of the first rotation-to-translation assembly 52, so that the rotational power of the first power part 51 The translation structure of the first rotation-to-translation assembly 52 is driven to translate in the second direction relative to the rotation structure of the first rotation-to-translation assembly 52 .

Specifically, the first power component 51 is usually a servo motor. The first translation mechanism 5 can use a rotation-to-translation structure such as a rack and pinion or a lead screw to realize translation, and can also use telescopic movement of a telescopic cylinder to realize translation. However, in this embodiment, it is preferable that the first translation mechanism 5 adopts a rotation-to-translation structure to achieve translation, so as to reduce production costs. When adopting the rack and pinion structure as the first rotation variable translation assembly 52, the first power part 51 is fixed on the first support plate 53, and is connected with the gear structure in the rack and pinion structure (that is, the first rotation variable translation assembly 52). Rotary structure) driving connection, and the rack structure in the rack and pinion structure (that is, the translation structure of the first rotation-translation assembly 52) is fixed on a support platform such as the ground, when the first power component 51 drives the gear structure to rotate, The gear structure will also move along the rack structure (at this time, the rack structure translates along the second direction relative to the gear structure), thereby driving the first support plate 53 connected to the first power component 51 to translate along the second direction; When the lead screw structure is used as the first rotation-to-translation assembly 52, the first power part 51 is drivingly connected to the screw in the lead screw structure (that is, the rotation structure of the first rotation-to-translation assembly 52), and the first support plate 53 is connected to the lead screw structure. The nut slider (that is, the translation structure of the first rotation-to-translation assembly 52) is connected. When the first power component 51 drives the screw to rotate, the nut slider translates on the screw along the second direction, thereby driving the connection with the nut slider. The first support plate 53 translates along the second direction.

In this way, by setting the first support plate 53 to provide a support position for the first power component 51 or the first rotation-to-translation assembly 52, at the same time, by connecting the first power component 51 to the rotation structure of the first rotation-to-translation assembly 52 , the first support plate 53 is driven to translate along the second direction by the rotational power of the first power component 51, so as to realize the function of the first translation mechanism 5 driving the chain plate assembly 2 to translate along the second direction.

Optionally, as shown in FIG. 6 , the first rotation-to-translation assembly 52 includes a rack 521 and a gear 522 that mesh with each other. The first power component 51 is connected to the first support plate 53 and is drivingly connected to the gear 522. The gear The bar 521 extends along the second direction and is used to be fixed on the supporting platform.

Specifically, the rack 521 and the gear 522 are respectively the translation structure and the rotation structure of the first rotation variable translation assembly 52, the rack 521 is usually fixed on a support platform such as the ground, and the first power component 51 is fixed on the first support plate 53 , and the motor shaft of the first power component 51 is drivingly connected to the gear 522 .
