Description

Technical Field

[0001] The invention relates to the field of explosive charging machines, in particular to a packaging device for emulsion explosive rolls. Background Art

[0002] Emulsion explosives are formed by using emulsifiers to evenly disperse droplets of oxidant salt aqueous solution in an oil phase continuous medium containing porous materials such as dispersed bubbles or hollow glass microspheres to form an oil-in-water type emulsion explosive. Emulsion explosives have high density, high detonation velocity, high intensity, good water resistance, small critical diameter, good initiation sensitivity, and detonator sensitivity in small diameters. They usually do not use pyrotechnics as sensitizers, and are safe to produce with less pollution. At present, many varieties have been developed, including open-pit emulsion explosives for open-pit mines, rock-type emulsion explosives for medium-hard rock blasting, and permissible emulsion explosives for underground coal mines, as well as small-diameter, low-detonation-velocity emulsion explosives for smooth surface blasting. Emulsion explosives are now widely used in various civil blasting operations, and their superiority is more evident in water- and humid blasting situations.

A Chinese invention with application number CN201010250355.8 discloses an automatic packaging machine for emulsion explosive rolls, which includes a frame, a quantitative filling device, a film placing device, a sheet film tube former, a vertical welding device, and a horizontal welding device. The quantitative filling device, the film placing device, the sheet film tube former, the vertical welding device, and the horizontal welding device are respectively installed on the frame.

When the emulsion explosives are filled from the top of the plastic tube film to the inside, the emulsion explosives move downward a large distance, and the downward flow and impact are likely to affect the composition ratio and charge density, thereby reducing the explosion effect. In addition, when filling downward, there is a large gap between the inside of the plastic tube film and the emulsion explosives, which is easy to cause air to be filled into the inside of the plastic tube film, affecting the charge density, and further reducing the actual explosion effect.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The piston shaft of the first hydraulic cylinder drives the injection tube to move upward inside the annular plastic film, and in the process of moving upward, the injection groove at the bottom of the injection tube is used to inject materials outward through the action of the rising injection mechanism, which is beneficial to reduce the drop height of the material during injection, and the injection tube is moved upward from the bottom of the annular plastic film to prevent air from being injected during the injection process, thereby reducing the impact on the charge density and improving the explosion effect.

[0018] 2. A one-way valve is installed inside the feed pipe to prevent the material from being poured out through the pouring groove at the bottom of the pouring cylinder.

Through the scraping action of the scraper bar, the material on the bottom surface of the filling cylinder is rotated and scraped toward the top of the filling groove and squeezed out, preventing part of the material from remaining on the bottom surface of the filling cylinder and ensuring sufficient filling material.

[0020] 4. The slide rail guides the movement of the circular pin so that the two U-shaped rods approach each other along the surface of the sliding rod in the movable groove as the slide rail moves, thereby driving the first clamping jaw and the second clamping jaw to approach each other. When the circular base moves downward and disengages from the bottom of the annular plastic film, the first clamping jaw and the second clamping jaw gather and clamp the annular plastic film under the perfusion cylinder to facilitate heat sealing of the bottom of the annular plastic film. When the perfusion cylinder moves upward, the bottom of the annular plastic film is clamped by the first clamping jaw and the second clamping jaw to prevent the perfusion cylinder from driving the annular plastic film to rise together through the contact friction on the side.

[0021] 5. When the two U-shaped rods approach each other and drive the first clamp and the second clamp to gather and clamp the annular plastic film under the filling tube, the two connecting rods approach each other as the U-shaped rods move, and drive the two limiting support rings to approach each other, and limit the side of the annular plastic film. After the filling tube moves upward and detaches from the upper inside of the annular plastic film, the two limiting support rings can limit the annular plastic film after filling, so that the staff does not need to hold it by hand to prevent it from tipping over, and it is convenient for the staff to heat-seal the top of the annular plastic film after filling.

Through the action of the rising filling mechanism, when the filling cylinder 3 moves upward, the material is poured outward along the filling groove 6;

[0036] Limiting blocks 7 are placed on both sides of the perfusion tube 3. A corresponding arc surface groove 701 is opened on the side of the limiting block 7 close to the perfusion tube 3. A lateral displacement mechanism is connected to the limiting block 7. The arc surface groove 701 is moved closer to the perfusion tube 3 through the action of the lateral displacement mechanism. The arc surface groove 701 is connected to an adsorption mechanism.

[0037] A circular hole 8 is provided on the processing table 1, a circular base 9 is placed inside the circular hole 8, a vertical moving mechanism is connected between the circular base 9 and the circular hole 8, the circular base 9 and the filling tube 3 have the same diameter, a plastic sealing machine 10 is placed on the processing table 1, a first clamping jaw 11 and a second clamping jaw 12 are placed on the processing table 1, a placement groove 13 is provided on one side of the first clamping jaw 11, the width of the placement groove 13 is the same as the width of the second clamping jaw 12, the first clamping jaw 11 and the second clamping jaw 12 are both connected with a synchronous clamping mechanism, and in the process of the circular base 9 moving downward through the vertical moving mechanism, the synchronous clamping mechanism makes the first clamping jaw 11 and the second clamping jaw 12 approach each other;During operation, in the prior art, during the process of making emulsion explosives, the emulsion explosives are usually filled from the top of the plastic tube film to the inside of the plastic tube film, and then the top of the plastic tube film is heat-sealed. When the emulsion explosives are filled from the top of the plastic tube film to the inside, the emulsion explosives move downward for a large distance, and the downward flow and impact are likely to affect the composition ratio and charge density, thereby reducing the explosion effect. In addition, when filling downward, there is a large gap between the inside of the plastic tube film and the emulsion explosives, which is easy to cause air to be filled into the inside of the plastic tube film, affecting the charge density and further reducing the actual explosion effect. The present technical solution can solve the above problems. The specific working method is as follows: first, by The circular base 9 is raised to the top of the circular hole 8 by the vertical movement mechanism, and then the connecting plate 4 is driven downward by the piston shaft of the first hydraulic cylinder 5, so that the filling cylinder 3 is moved vertically downward, and the bottom of the filling cylinder 3 is in contact with the top of the circular base 9, and then the two plastic films to be heat-sealed are placed in the arc grooves 701 on the adjacent sides of the two limit blocks 7 respectively, and the plastic films are adsorbed on the arc grooves 701 by the adsorption mechanism to prevent the plastic films from falling, and then the two limit blocks 7 are synchronously moved close to the filling cylinder 3 and the circular base 9 by the lateral displacement mechanism. When the arc grooves 701 on the limit blocks 7 clamp the plastic films between the filling cylinder 3 and the circular base 9, the plastic films are pressed between the filling cylinder 3 and the circular base 9. When the filling tube 3 and the circular base 9 are formed, the stop block 7 stops moving, and the excess part of the two plastic films on the adjacent side is heat-sealed by the plastic sealing machine 10, so that the two plastic films are heat-formed into a circular ring shape around the filling tube 3 and the circular base 9, and are sleeved on the filling tube 3 and the circular base 9. Then, the two stop blocks 7 are synchronously moved in the opposite direction by the lateral displacement mechanism, so as to be away from the filling tube 3 and the circular base 9, and then the circular base 9 is reversely moved by the vertical movement mechanism and moves downward along the circular hole 8. In the process of the circular base 9 moving downward, the first clamping jaw 11 and the second clamping jaw 12 are moved to the bottom of the filling tube 3 by the synchronous clamping mechanism. The second clamp 12 moves to the inside of the placement groove 13 of the first clamp 11, gathers and clamps the annular plastic film below the filling cylinder 3, and then uses the plastic sealing machine 10 to heat-seal the gathered position of the bottom of the annular plastic film. Finally, the piston shaft of the first hydraulic cylinder 5 drives the filling cylinder 3 to move upward inside the annular plastic film, and in the process of moving upward, the filling groove 6 at the bottom of the filling cylinder 3 is filled with materials outward through the action of the rising filling mechanism, which is conducive to reducing the drop height of the material during filling, and the filling cylinder 3 is moved upward from the bottom of the annular plastic film to prevent air from being injected during the filling process, reducing the impact on the charge density, which is conducive to improving the explosion effect. ;

[0038] As a further embodiment of the present invention, the rising filling mechanism includes an extrusion column 14, which is rotatably connected to the top of the U-shaped frame 2, and the bottom end of the extrusion column 14 is slidably sealed inside the filling cylinder 3. A feed pipe 15 is fixedly connected to the top of the side of the filling cylinder 3, and a one-way valve 16 is fixedly installed inside the feed pipe 15; when working, the material is transported to the inside of the filling cylinder 3 through the feed pipe 15, and the one-way valve 16 is installed inside the feed pipe 15 to prevent the material from being poured out through the filling groove 6 at the bottom of the filling cylinder 3. The extrusion generated causes part of the material to be squeezed out along the feed pipe 15. When the filling cylinder 3 moves upward with the piston shaft of the first hydraulic cylinder 5, the bottom end of the extrusion column 14 is slidably sealed inside the filling cylinder 3, and the space inside the filling cylinder 3 is gradually reduced, so that when the filling cylinder 3 moves upward inside the annular plastic film, the filling groove 6 at the bottom of the filling cylinder 3 synchronously pours the material outward, completing the material pouring inside the annular plastic film.

The technical solution can solve the above problems. The specific working method is as follows: when the filling cylinder 3 moves upward, the extrusion column 14 moves downward relatively to extrude the material. When the extrusion column 14 moves upward, the second gear 20 is driven to rotate by the output shaft of the motor 19, and the second gear 20 is meshed with the first gear 18, thereby driving the extrusion column 14 to rotate, so that the bottom end of the extrusion column 14 is slidably sealed inside the filling cylinder 3 and rotates while moving relatively. When the bottom of the extrusion column 14 is close to the bottom surface inside the filling cylinder 3, the bottom of the scraper bar 24 first contacts the bottom surface inside the filling cylinder 3, and the rotation of the extrusion column 14 drives the scraper bar 24 to rotate. During the rotation process, the bottom end of the scraper bar 24 rotates the material toward the position of the filling groove 6, and as the bottom of the extrusion column 14 and the bottom surface inside the filling cylinder 3 gradually approach each other, the scraper bar 24 is moved toward the strip groove 23.
