Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a switching device for the feed belt of a drug loading machine. Background Technology

[0002] In the continuous and automated production of emulsion explosives, due to the limitations of the on-site environment layout, it is impossible to switch materials between large and small diameter charging machines. If multiple conveyor belts are added, it will cause interference between on-site equipment positions, reduce the production space, and increase production and maintenance costs. Therefore, how to economically and effectively switch materials between large and small diameter charging machines has become an urgent task for enterprises. Currently, there are two methods for loading emulsion explosives into different diameter loading machines: one is to pump the material directly to a conveyor belt, where the material undergoes an sensitization process before being pumped to the corresponding conveyor belt and then into the corresponding loading machine; the other is to use a fixed belt and a moving belt, with the fixed belt corresponding to one loading machine and the moving belt corresponding to another loading machine, thus enabling loading machine switching. However, due to interference from the on-site workshop foundation and the placement of the loading machines, neither of these two methods can effectively solve the problem of on-site loading machine switching. Therefore, a new and economical loading machine switching method must be adopted. To comprehensively address on-site assembly issues, a switching device for the feed belt of the charging machine was designed. Utility Model Content

The top of the movable belt support is equipped with a large-diameter drug delivery conveyor belt and a small-diameter drug delivery conveyor belt arranged in a left-right distribution, and the bottom of the movable belt support is fixed with multiple casters.

[0005] Preferably, the large-diameter drug-loading conveyor belt and the large-diameter drug-loading machine hopper are arranged on the same side, and the small-diameter drug-loading conveyor belt and the small-diameter drug-loading machine funnel are arranged on the same side.

Detailed Implementation

[0014] Reference Figure 1-3 The feeding belt switching device for the drug loading machine includes a frame 1, a fixed conveyor belt 2 fixed on the surface of the frame 1, a large-diameter drug loading machine hopper 3 and a small-diameter drug loading machine funnel fixed on the surface of the frame 1 and on both sides of the fixed conveyor belt 2, a fixed bracket 5 fixed on the surface of the frame 1, a push cylinder 6 fixed on the top of the fixed bracket 5, and a movable belt bracket 7 fixed on the moving end of the push cylinder 6. Proximity switches are installed at both ends of the cylinder body of the push cylinder 6. The proximity switches at both ends and the bottom support rod of the movable belt bracket 7 are on the same vertical plane. When the piston rod of the push cylinder 6 extends or retracts, it drives the movable belt bracket 7 to move horizontally. During the movement, the support rods at the bottom of the movable belt bracket 7 located on both sides of the push cylinder 6 can sense the proximity switches at both ends, thereby reflecting the position information of the movable belt bracket 7 and obtaining the arrival signal of the movable belt bracket 7.

[0015] The top of the movable belt support 7 is equipped with a large-diameter drug delivery conveyor belt 8 and a small-diameter drug delivery conveyor belt 9 arranged in a left-right distribution, and the bottom of the movable belt support 7 is fixed with multiple casters 71.

[0016] The large-diameter drug-loading conveyor belt 8 and the large-diameter drug-loading machine hopper 3 are arranged on the same side, and the small-diameter drug-loading conveyor belt 9 and the small-diameter drug-loading machine funnel are arranged on the same side.

[0017] The surface of the frame 1 is fixed with a track 10 for linearly limiting the casters 71.

[0018] It also includes a sensitizer 11, the outlet of which is provided with a primary conveyor belt 12, and a secondary conveyor belt 13 is inclinedly arranged at the end of the primary conveyor belt 12, with the end of the secondary conveyor belt 13 arranged above the fixed inclined conveyor belt 2.

[0019] Switch the belt conveyor terminal controller. The terminal controller is connected to the push cylinder 6, the large-diameter drug delivery conveyor belt 8, the small-diameter drug delivery conveyor belt 9, the sensitizer 11, the primary conveyor belt 12, and the secondary conveyor belt 13.

[0020] When this device is in use, after the material sensitization is completed, it is conveyed to the small diameter drug loading conveyor belt 9 through the primary conveyor belt 12, the secondary conveyor belt 13 and the fixed inclined conveyor belt 2. At this time, the initial state is: the discharge end of the fixed inclined conveyor belt 2 corresponds to the small diameter drug loading conveyor belt 9, the push cylinder 6 is in a retracted state, the discharge end of the small diameter drug loading conveyor belt 9 is aligned with the small diameter drug loading machine hopper 4, the small diameter drug loading conveyor belt 9 runs in the forward direction, conveying the material to the small diameter drug loading machine hopper 4, and then entering the small diameter drug loading equipment; When switching is required, and the small-diameter drug-loading conveyor belt 9 stops operating, the cylinder 6 is pushed out, the movable belt bracket 7 moves to the right as a whole, and after the cylinder 6 pushes into place and provides feedback on the position signal, the discharge end of the fixed conveyor belt 2 corresponds to the large-diameter drug-loading conveyor belt 8, and the discharge end of the large-diameter drug-loading conveyor belt 8 corresponds to the large-diameter drug-loading machine hopper 3. The fixed conveyor belt 2 and the large-diameter drug-loading conveyor belt 8 start operating, and the material enters the large-diameter drug-loading machine hopper 3, and then enters the large-diameter drug-loading equipment. Similarly, when switching back to a smaller diameter loading device, first stop the belt conveyor, push cylinder 6 to retract to the correct position and receive the feedback signal, then start the corresponding left and right conveyor belts to achieve automatic switching between the large and small diameter loading machines.
