Description

Technical field:

[0001] The utility model relates to the technical field of emulsion explosive production equipment, in particular to an interval conveying control device for emulsion explosive packaging boxes. Background technology:

[0002] Emulsion explosives are a kind of water-in-oil type latex explosives formed by uniformly dispersing droplets of aqueous solution of oxidant salts in an oil phase continuous medium containing porous substances such as dispersed bubbles or hollow glass microspheres with the help of emulsifiers. In the production process, the prepared emulsion explosive rolls are packaged in packaging boxes. After packaging, the packaging boxes are placed on a belt conveyor, which transports the packaging boxes spaced apart from each other to the loading station in sequence for loading.

[0003] To ensure safety, a certain safety distance must be maintained between two adjacent packaging boxes during transportation to prevent the emulsion explosive in one of the packaging boxes from accidentally exploding and detonating the adjacent packaging box; however, in actual production, the packaging station is far away from the loading station, and multiple end-to-end belt conveyors are used for transportation on site. Due to the existence of the connection between the belt conveyors and the unevenness of the belt conveyors, the distance between adjacent packaging boxes is shortened during the transportation process. Therefore, it is required to arrange patrol personnel on site to continuously observe. When the distance between adjacent packaging boxes is shortened and does not meet the requirements, the patrol personnel will make timely adjustments and shift the subsequent packaging boxes. Such operation is not only labor-intensive but also has high labor costs. Utility model content:

[0004] The utility model aims to provide an emulsion explosive packaging box interval conveying control device which is beneficial to reducing labor cost and labor intensity.

[0005] The utility model is implemented by the following technical scheme: an interval conveying control device for emulsion explosive packaging boxes, which includes a photoelectric switch, a driving cylinder and a plurality of roller conveyors connected in sequence end to end;

[0006] A plurality of groups of the opposing photoelectric switches are installed on the frame of each roller conveyor at equal intervals along the conveying direction, and the two opposing photoelectric switches in each group are symmetrically placed on both sides of the frame of the roller conveyor;

[0007] A support beam is fixed on the frame below the driving roller of the roller conveyor corresponding to each group of the opposing photoelectric switches, and a rotating shaft is installed on the frame in front of the support beam along the transmission direction of the roller conveyor, and the rotating shaft is arranged parallel to the driving roller of the roller conveyor; a limit plate is fixed on the upper side wall of the rotating shaft, a connecting rod is fixed on the lower side wall of the rotating shaft, the telescopic end of the driving cylinder is hinged to the end of the connecting rod, and the cylinder end of the driving cylinder is hinged to the support beam;

[0008] The opposing photoelectric switch is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the solenoid valve on the air path of the driving cylinder.

[0009] Furthermore, the through-beam photoelectric switch is fixed to the frame of the roller conveyor through a mounting plate, a long groove is provided on the mounting plate along the conveying direction of the roller conveyor, and the through-beam photoelectric switch is installed in the long groove.

[0010] The advantages of the utility model are as follows: when each group of opposing photoelectric switches detects that a packing box has passed, the detected signal will be fed back to the controller, and the controller can calculate the time interval between two adjacent packing boxes passing through each group of opposing photoelectric switches, and compare it with the set time interval. When the detected value is less than the set value, it means that the distance between the packing box passing through the opposing photoelectric switch and the front packing box is less than the specified requirement. The controller controls the telescopic rod of the driving cylinder to extend and the limit plate to stand up to block and limit the packing box. At this time, the front packing box continues to be conveyed forward by the roller conveyor until the detected time interval value reaches the set value. The controller controls the telescopic rod of the driving cylinder to retract and the limit plate to tilt downward to release the obstruction to the packing box, thereby ensuring the distance from the front packing box. By analogy, it can be ensured that the distance between each two adjacent packing boxes meets the production requirements, thereby effectively avoiding safety hazards, and does not require manual assistance, thereby reducing labor costs and labor intensity.

[0018] A support beam 3 is fixed on the frame below the drive roller of the roller conveyor 1 corresponding to each group of the photoelectric switches 2, and a rotating shaft 4 is installed on the frame in front of the support beam 3 along the transmission direction of the roller conveyor 1. The rotating shaft 4 is arranged parallel to the drive roller of the roller conveyor 1; a limit plate 5 is fixed on the upper side wall of the rotating shaft 4, and the limit plate 5 is movably placed between the two drive rollers. A connecting rod 6 is fixed on the lower side wall of the rotating shaft 4, and the telescopic end of the driving cylinder 7 is hinged to the end of the connecting rod 6, and the cylinder end of the driving cylinder 7 is hinged to the support beam 3; when the telescopic rod of the driving cylinder 7 is extended, the connecting rod 6 drives the rotating shaft 4 to rotate, and at the same time, drives the limit plate 5 to stand up, so as to block the advancement of the packaging box 9; and when the telescopic rod of the driving cylinder 7 is retracted, the connecting rod 6 drives the rotating shaft 4 to rotate in the opposite direction, and at the same time, drives the limit plate 5 to tilt downward around the rotating shaft 4 until the top edge of the limit plate 5 is inclined against the side wall of one of the drive rollers, so as to facilitate the smooth passage of the packaging box 9.

When the detected value is less than the set value, it means that the distance between the packing box 9 passing through the photoelectric switch 2 and the front packing box 9 is less than the specified requirement. The controller controls the telescopic rod of the driving cylinder 7 to extend, and the limit plate 5 to stand up, and the packing box 9 is blocked and limited. At this time, the front packing box 9 continues to be conveyed forward by the roller conveyor 1 until the detected time interval value reaches the set value. The controller controls the telescopic rod of the driving cylinder 7 to retract, and the limit plate 5 tilts downward to release the obstruction to the packing box 9, thereby ensuring the distance from the front packing box 9.
