DETAILED DESCRIPTION

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figure 2 and Figure 3 As shown, the embodiment of the present application discloses a cross-linking agent dispensing device for fracturing fluid, comprising: a conveyor belt 3 and a dividing plate body 4, the dividing plate body 4 is rotatably arranged above the conveyor belt 3; a plurality of pairs of clamping assemblies 5 are rotatably arranged on the dividing plate body 4, including a first clamping member 51 and a second clamping member 52 symmetrically arranged, for clamping the bottle member 2; a waist-shaped hole 53, which passes through the clamping assembly 5 in a vertical direction; a movable shaft 54, which is slidably arranged in the waist-shaped hole 53 in a vertical direction; a driving component 6, which is slidably arranged in the dividing plate body 4, and the movable shaft 54 ​​is arranged on the driving component 6; an adjusting component, which is used to drive the driving component 6 to slide along the radial direction of the dividing plate body 4, so that the movable shaft 54 ​​pushes the clamping assembly 5 to rotate, thereby changing the opening size between the first clamping member 51 and the second clamping member 52.

[0021] During specific use, on the one hand, the conveyor belt 3 continuously conveys the neatly arranged bottles 2 toward the dividing plate body 4. As the dividing plate body 4 rotates, it drives different clamping components 5 to receive the bottles 2 one by one, and the bottles 2 are spaced and diverted so that the bottles 2 can be positioned in subsequent processes, thereby facilitating the completion of the packaging operation of the bottled cross-linking agent.

[0022] On the other hand, by adjusting the assembly to drive the driving component 6 to slide in the radial direction of the dividing plate body 4, the movable shaft 54 ​​can push the clamping assembly 5 to rotate, thereby changing the opening size between the first clamping member 51 and the second clamping member 52, so as to allow bottles 2 of different diameters to be placed and positioned; by using the utility model, setting a dividing plate body 4 can meet the positioning requirements of bottles 2 of different diameters, effectively improving the scope of application of the utility model, and can effectively reduce the packaging production cost of bottled cross-linking agents.

[0023] It can be understood that, in the present invention, a plurality of pairs of clamping assemblies 5 are arranged in a circumferential array on the indexing plate body 4 to ensure that the spacing between each bottle member 2 is the same.

[0024] Specifically, the adjustment component includes: a turntable 71, which is rotatably arranged in the dividing plate body 4; an adjustment slope 72, which is arranged on the turntable 71 and is used to resist the end of the driving component 6 away from the clamping component 5; a limit block 73, which is arranged on the driving component 6; a spring 74, which is sleeved on the driving component 6 and is located on the side of the limit block 73 away from the turntable 71; a first drive motor, which is transmission-connected to the turntable 71 and is used to drive the turntable 71 to rotate.

[0025] During specific use, the turntable 71 is driven to rotate by the first driving motor (not shown in the figure), which can drive the adjusting inclined surface 72 to contact the driving component 6, thereby driving the driving component 6 to slide in the direction away from the turntable 71 and squeeze the spring 74; at the same time, the movable shaft 54 ​​also slides in the waist-shaped hole 53, squeezing the first clamping member 51 and the second clamping member 52, so that the opening between the first clamping member 51 and the second clamping member 52 becomes larger, so that the bottle 2 with a larger diameter can be placed; of course, the first driving motor is reversed, and the spring 74 stretches, which can push the driving component 6 to slide in the direction close to the turntable 71, so that the opening between the first clamping member 51 and the second clamping member 52 becomes smaller, so that the bottle 2 with a smaller diameter can be placed.

[0026] Of course, in the present invention, a plurality of adjusting inclined surfaces 72 are arranged in a circular array on a turntable 71 , respectively corresponding to a plurality of pairs of clamping assemblies 5 , and the adjustment of a plurality of pairs of clamping assemblies 5 can be completed by rotating a turntable 71 .

[0028] Preferably, the device also includes: a rack 75, which is arranged on the turntable 71 and has internal teeth; a gear 76, which is arranged on the output shaft of the first drive motor, and the gear 76 and the rack 75 are installed in meshing engagement; of course, the first drive motor uses a self-locking stepper motor to ensure the adjustment accuracy, and the first drive motor can be powered by a battery to prevent the dividing plate body 4 from rotating and causing the wires to be entangled.

[0029] Preferably, the device also includes: a first clamping surface, arranged on the first clamping member 51; a second clamping surface, arranged on the second clamping member 52; a V-shaped angle for placing the bottle 2 is formed between the first clamping surface and the second clamping surface; and the bottle 2 is quickly positioned through tangential contact between the V-shaped angle and the bottle 2.

[0030] Specifically, the device further includes: a storage slot 41 , which is provided on the indexing plate body 4 and is used for installing the clamping assembly 5 ; and a hinge shaft 42 , which is provided in the storage slot 41 and passes through the clamping assembly 5 .

[0031] It is worth mentioning that the dividing plate body 4 and the turntable 71 can be rotatably installed through the bearing of the turntable 71, and driving the dividing plate body 4 to rotate and the conveyor belt 3 to move is a well-known technology in the art and will not be described in detail here.
