Detailed Description

The present application will be described in further detail with reference to test examples and specific embodiments. It should not be construed that the scope of the above subject matter of the present application is limited to the following embodiments, and all techniques realized based on the present application are within the scope of the present application.

1-4, an explosive middle package 500 turnover mechanism comprises a frame 400 and a belt group 100 arranged on the frame 400, wherein the belt group 100 comprises at least two belts, two belts of the at least two belts are a first belt 110 and a second belt 120, the first belt 110 and the first belt 110 are sequentially arranged from bottom to top, and the movement speed of the uppermost first belt 110 is different from that of the lowermost second belt 120; the channel formed by the juxtaposition of two belt sets 100 is a flip channel 300, with all belt movement directions of one belt set 100 moving in the direction B and all belt movement directions of the other belt set 100 moving in the direction C, as opposed to the directions B and C of fig. 1 and 2.

Of course, one belt set 100 may be provided with 3 or more belts arranged in order from bottom to top, with respect to the arrangement of the rotational speeds, the belt rotational speed in the middle, between the uppermost belt rotational speed and the lowermost belt rotational speed, preferably the rotational speed of the middle belt is equal to the uppermost belt rotational speed or equal to the lowermost belt rotational speed.

If only two belts are provided for one belt set 100, as in fig. 1 and 2, only the first belt 110 and the second belt 120 are included, the first belt 110 and the first belt 110 are operated at different speeds, and different drum drives are used. Two drums are arranged at two ends of the first belt 110, one drum is in driving rotation, the other drum is in driven rotation, and the driving rotation drum is driven by a motor; the same is true of the second belt 120, but the drums of the first belt 110 and the second belt 120 are different, not the same drum, so that the operating speeds of the first belt 110 and the second belt 120 are different.

For the convenience of adjustment, one belt set 100 is movably fixed to the frame 400, as shown in fig. 1 and 2, the first belt 110 belt set 100 is moved along the direction B, the second belt 120 belt set 100 is moved along the direction C, one of the first belt 110 belt set 100 or the second belt 120 belt set 100 is movably fixed to the frame 400, specifically, for the convenience of adjustment of the distance between the first belt 110 belt set 100 and the second belt 120 belt set 100, that is, for the convenience of adjustment of the passing width of the turning channel 300, for the convenience of adjustment of the passing width of the explosive medium bag 500, the distance between the first belt 110 belt set 100 and the second belt 120 belt set 100 is not too wide or too narrow, at this time, the distance needs to be adjusted, and after the distance is adjusted, the first belt 110 belt set 100 is fixed again, so as to avoid the distance change during the later operation. In a specific fixing manner, a hole can be formed in the frame 400, and the bolt is used for fixing, so that the distance is required to be adjusted by unscrewing the bolt and moving along the hole, and after the distance is adjusted, the bolt is screwed down.

The two sides of the outlet end of the turning channel 300 are provided with side baffles 200, the two side baffles 200 are arranged to form a passage channel of the explosive middle ladle 500, the explosive middle ladle 500 coming from the turning channel 300 can enter the passage channel, the explosive middle ladle 500 entering the passage channel is prevented from deflecting by the side baffles 200 at the two sides, the distance between the two side baffles 200 is adjustable, the adjusting range is 200 mm-500 mm, when installed, all of the straps in the strap set 100 contact the charge drum 500, i.e., the total height of all of the straps cannot exceed the height at which the charge drum 500 enters the inversion channel 300, particularly the uppermost strap and the lowermost strap contact the charge drum 500, so as to invert the charge drum 500 90 degrees during operation.

When the belt conveyor is specifically installed, the distance between the two belt sets 100 is adjustable, and the adjustment range is 200 mm-500 mm. The specific parameters are adjusted and installed according to the field use, so that the explosive middle package 500 is just turned over by 90 degrees when running to the tail end of the turning channel 300, and enters the passing channel just after turning over, meanwhile, the clamping pressure of the two belt groups 100 is not too tight, so that the belts can drive the explosive middle package 500 to run by friction force, and meanwhile, the explosive middle package 500 can be allowed to rotate in the turning channel 300, and the speed of the belts, the pressing force of the two belts, the friction force and the length, the width and the weight of the explosive middle package 500 are considered.

When the explosive cartridge overturning mechanism is used, an emulsified explosive cartridge film is subjected to thermal shrinkage into a middle package by a middle package thermal shrinkage machine, 20 explosive cartridge films are generally divided into two rows, namely 2×10 packages, when the explosive middle package 500 is overturned vertically, the end face formed by the end part of the explosive middle package 500 is grounded, namely the end face of the explosive middle package 500 is grounded, at the moment, the explosive middle package 500 can be vertically stable and cannot topple over, however, the explosive middle package 500 entering the explosive middle package overturning mechanism is not vertically placed, but is horizontally placed, namely the large cross section of the explosive middle package 500 is horizontally placed, the explosive middle package 500 needs to be overturned in the overturning mechanism to form vertical placement, after entering an overturning channel 300 formed by a belt group 100, the explosive middle package 500 is subjected to a speed difference of an upper belt and a lower belt, the belt speed is high, the belt speed is low, the explosive middle package 500 is driven to walk forwards by the belt with the speed difference, the belt with the speed is relatively high, the explosive middle package 500 is driven to rotate by the friction force of the explosive middle package 500, the explosive middle package is driven to overturn, and the explosive middle package 500 is overturned, so that the explosive middle package 500 is overturned to enter the overturning channel 300 from the vertical channel to finish the overturning channel, and the overturning process is finished.
