The working principle of the online valve preassembling device of the fire extinguisher is as follows:
the distance between the clamping rollers on the two sides of the conveying belt is larger than the diameter of the fire extinguisher, so that the fire extinguisher can move along with the conveying belt to the position between the clamping rollers on the two sides, then the horizontal reciprocating driving mechanism drives the clamping rollers to move towards the fire extinguisher, the fire extinguisher is clamped in the middle of the clamping rollers on the two sides, the rotary driving mechanism drives the clamping rollers to rotate, the fire extinguisher bottle body rotates along with the clamping rollers synchronously, and the fire extinguisher bottle body can rotate by utilizing the rotation of the fire extinguisher bottle body, so that a worker can easily insert a valve with an assembled siphon tube into dry powder (fire extinguishing agent) in the bottle and pre-install the. In the valve preassembling process, the conveying belt does not need to stop, and the normal conveying beat cannot be influenced.
Furthermore, the distance between the clamping rollers on the two sides of the conveying belt is gradually reduced from the top end of the clamping roller to the bottom end of the clamping roller, so that the clamping force applied to the fire extinguisher by the clamping rollers on the two sides is gradually reduced from bottom to top, the clamping force forms upward branch acting force and horizontal branch acting force, when the fire extinguisher is driven to rotate by the clamping rollers, the fire extinguisher gradually rises under the action of the upward branch acting force, the bottom of the fire extinguisher is separated from the conveying belt, and the phenomenon that the fire extinguisher rotates to cause large abrasion to the conveying belt and influence the service life of the conveying belt is avoided. After the fire extinguisher rises for a certain distance, the upward acting force applied to the fire extinguisher by the clamping roller is equal to the gravity of the fire extinguisher, and the fire extinguisher is kept at the height and cannot rise continuously.

Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, wherein the embodiments of the present invention are described in detail with reference to the accompanying drawings, for example, the shapes and structures of the respective members, the mutual positions and connection relationships between the respective portions, the functions and operation principles of the respective portions, and the like.
Example 1:
this embodiment provides an online valve pre-installation device of fire extinguisher to reduce artifical intensity of labour.
As shown in fig. 1 and 2, the fire extinguisher online valve preassembling device of the present embodiment is composed of rotatable clamping rollers respectively located at two sides of a conveyor belt 1, wherein two clamping rollers at one side are driven clamping rollers 2, the driven clamping rollers 2 are mounted on a horizontal reciprocating driving mechanism 3, and the horizontal reciprocating driving mechanism 3 can be made of an air cylinder; one of the clamping rollers on the other side is a driving clamping roller 4, and the driving clamping roller 4 is fixed on a rotation driving mechanism 5 (which can adopt a motor) beside the conveying belt 1. Driven pinch roll 2 is perpendicular setting, and initiative pinch roll 4 sets up for the slope, and the incline direction of initiative pinch roll 4 from top to bottom is close driven pinch roll 2 gradually, just so makes the interval of the pinch roll of 1 both sides of conveyer belt reduce to the bottom of pinch roll by the top of pinch roll gradually.
In this embodiment, the surface of the grip roller is provided with a rubber elastic layer to reduce the possible damage to the surface of the fire extinguisher and to improve the clamping effect on the fire extinguisher.
In this embodiment, the fire extinguisher online valve pre-loading device further comprises a blocking mechanism 7 for controlling the travel of the fire extinguisher 6, said blocking mechanism 7 being located in front of the grip roller (in the conveying direction of the conveyor belt 1, i.e. in the direction of the arrow in fig. 1), i.e. the fire extinguisher can travel to the grip roller only through the blocking mechanism 7. The blocking mechanism 7 adopts a horizontal cylinder as a function, the horizontal cylinder is positioned on one side of the conveying belt 1, a piston rod of the horizontal cylinder faces the direction of the conveying belt 1, and when the piston rod extends out, a blocking rod can be formed on the conveying belt 1 to block the fire extinguisher 6 on the conveying belt 1.
In the process of preassembling the fire extinguisher valve, the fire extinguisher 6 without the valve on the conveyor belt 1 (namely the fire extinguisher 6 with the next valve to be assembled) can be stopped by the blocking mechanism 7 so as to prevent the fire extinguisher 6 from colliding with the fire extinguisher 6 with the valve being assembled to influence the normal assembly work, and after the valve of the fire extinguisher 6 is assembled, the next fire extinguisher 6 is put to move to the clamping roller.
The working principle of the online valve preassembling device of the fire extinguisher is as follows:
the distance between the driving clamping roller 4 and the driven clamping roller 2 is larger than the diameter of the fire extinguisher 6, the fire extinguisher 6 can move to the positions between the clamping rollers on the two sides along with the conveying belt 1, then the horizontal reciprocating driving mechanism 3 drives the driven clamping roller 2 to move towards the fire extinguisher 6, so that the fire extinguisher 6 is clamped in the middle of the clamping rollers on the two sides, then the driving mechanism 5 is rotated to drive the driving clamping roller 4 to rotate, the fire extinguisher 6 rotates synchronously along with the clamping rollers, a worker only needs to vertically insert a valve with an assembled siphon tube into dry powder (fire extinguishing agent) in a bottle and press the valve at the bottle mouth of the fire extinguisher 6, the valve can be assembled on the bottle mouth by utilizing the rotation of the fire extinguisher 6, and.
When the valve is preassembled to reach the set torque, the rotation driving mechanism 5 stops rotating, the driving clamping roller 4 stops rotating, and the driven clamping roller 2 is driven by the horizontal reciprocating driving mechanism 3 to move towards the direction far away from the fire extinguisher 6, so that the fire extinguisher 6 is loosened, and the fire extinguisher 6 can continue to move along with the conveying belt 1. In the capping process, the conveyor belt 1 does not need to be stopped, and the normal conveying rhythm cannot be influenced.
As shown in figure 3, the distance between the clamping rollers on the two sides of the conveying belt 1 is gradually reduced from the top ends of the clamping rollers to the bottom ends of the clamping rollers, so that the clamping force applied to the fire extinguisher 6 by the clamping rollers on the two sides is gradually reduced from bottom to top, the clamping force forms an upward component action force and a horizontal component action force, when the fire extinguisher 6 is driven by the clamping rollers to rotate, the fire extinguisher 6 gradually rises under the action of the upward component action force, the bottom of the fire extinguisher 6 is separated from the conveying belt 1 to be in contact with the conveying belt 1, and the phenomenon that the conveying belt 1 is greatly abraded when the fire extinguisher 6 rotates is avoided, and the service life of the conveying belt 1 is. After the fire extinguisher 6 rises a certain distance, the upward component force applied to the fire extinguisher 6 by the grip roller is equal to the gravity of the fire extinguisher 6, and the fire extinguisher 6 is maintained at that height and does not rise further.
The present invention has been described in detail with reference to the accompanying drawings, and it is apparent that the present invention is not limited by the above embodiments, and various insubstantial improvements can be made without modification to the present invention.
