Description

Technical Field

[0001] This invention relates to the field of industrial production technology, specifically to an automatic film-coating device for precision temperature-controlled emulsion explosives. Background Technology

[0002] Emulsion explosives are explosives prepared using emulsion technology. They are typically composed of an aqueous phase, an oil phase, an emulsifier, and a sensitizer. Emulsion explosives have high energy density and good plasticity, and are widely used in blasting engineering. To improve the stability of emulsion explosives and facilitate their transportation and storage, they need to undergo a coating treatment during production.

[0003] A film coating machine is a device used to coat emulsion explosives. During operation, the machine unfolds the rolled-up packaging film, bends it into a cylindrical shape, and then seals the joints using heat pressing. This allows the emulsion explosive to be poured into the cylindrical packaging film, achieving the film coating process. However, traditional film coating machines maintain a constant temperature on the heat press plate. When the film unfolding speed changes, the temperature of the heat press plate cannot automatically adjust. When the unfolding speed increases, the heat pressing time at the joints shortens, resulting in a weak seal and potential leakage and waste of the injected emulsion explosive. Conversely, a slower unfolding speed can lead to overheating at the joints, affecting the quality of the packaging film and reducing the film coating effect. Furthermore, during emulsion explosive production, the explosive needs to be continuously poured into the packaging film. When the emulsion explosive is cut, it can easily be squeezed out from the cut points, causing spillage and hindering production.

[0004] To address this, an automatic film-applying device for precision temperature-controlled emulsion explosives is proposed. Summary of the Invention

[0008] Preferably, the segmented mechanism includes an outer housing, which is fixedly connected to the top of the machine body. A rotating shaft is rotatably connected to the top of the outer housing. A second transmission belt drives between the output shaft of the motor and the rotating shaft. Two rotating columns are rotatably connected inside the outer housing, and transmission gears are fixedly connected to the ends of the two rotating columns near the rotating shaft. The two transmission gears are meshed. A first transmission belt drives between the rotating shaft and the upper rotating column. Two first hydraulic rods are fixedly connected to the inner wall of the outer housing on the side away from the transmission gears. Protrusions are fixedly connected to the telescopic ends of the first hydraulic rods and the side of the rotating column near the first hydraulic rods. The inner wall of the outer housing on the side near the transmission gears is fixedly connected to the first hydraulic rods. A first horizontal plate is fixedly connected to the outer shell. A second horizontal plate is fixedly connected to the inner wall of the outer shell away from the first horizontal plate. A second hydraulic rod is fixedly connected to the inside of the first horizontal plate. A first clamping plate is fixedly connected to the end of the second hydraulic rod away from the inner wall of the outer shell. A third hydraulic rod is fixedly connected to the inside of the first clamping plate. A blade is fixedly connected to the side of the first clamping plate away from the second hydraulic rod. A fourth hydraulic rod is fixedly connected to the inside of the second horizontal plate. A second clamping plate is fixedly connected to the end of the fourth hydraulic rod away from the inner wall of the outer shell. Another blade is fixedly connected to the side of the second clamping plate away from the fourth hydraulic rod. Extrusion plates are fixedly connected to the sides of the two rotating columns that are away from each other. A limit tube is fixedly connected to the top of the first horizontal plate.

[0009] Preferably, the slider is in contact with the outer surface of the resistance wire, the slider, the resistance wire and the heating wire are connected in series, and the side of the fixing plate closest to the mounting plate is tapered.

[0010] Preferably, the two heat-conducting plates are attached to each other on their adjacent sides, the end of the driving member away from the threaded post passes through the rotating member, and the slider is located above the center point of the rotating member.

[0011] Preferably, there is a gap between the outer tube and the inner tube, the outer tube is C-shaped, and there are gaps between both ends of the outer tube and both sides of the fixing plate.

[0012] Preferably, the thickness of the extrusion plate is half the distance between the two rotating columns, and the first hydraulic rod, the second hydraulic rod, the fourth hydraulic rod and the third hydraulic rod are all composed of a cylinder and a telescopic rod slidably connected.

[0013] Preferably, the upper first hydraulic rod is connected to the second and fourth hydraulic rods through a pipe, and the lower first hydraulic rod is connected to the third hydraulic rod through a hose.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] Firstly, the position of the slider can change with the rotation speed of the rotating parts. This design allows for precise automatic adjustment of the temperature of the heating wire according to the speed of the emulsion explosive film application. This ensures that the heat-conducting plate can heat-press and seal the overlapping ends of the film roll at different film application speeds, preventing problems such as leakage of emulsion explosive due to insecure sealing at the film roll joints and overheating of the film roll. This also prevents waste of emulsion explosive and improves the film application effect.

[0017] The manual rotation of the drive unit allows for adjustment of the initial length of the resistance wire connected to the circuit, thereby regulating the initial temperature of the heat-conducting plate. This design enables preliminary temperature adjustment of the heat-conducting plate based on the material of the film, expanding the application range of the device and improving its applicability.

[0018] Secondly, when the two extrusion plates rotate to the closed state, they extrude the emulsion explosive after the film is applied, causing the emulsion explosive in the cylindrical roll film to be segmented. This design can prevent the emulsion explosive from being squeezed out from the cutting point when segmenting the emulsion explosive, thus preventing waste of the emulsion explosive. At the same time, it can prevent the emulsion explosive from sticking to the blade during cutting, ensuring the effectiveness of the blade and enabling the blade to cut the emulsion explosive continuously.

[0019] While the emulsion explosive is segmented, the first and second clamps can fasten the metal clips to the ends of the emulsion explosive, making the ends of the emulsion explosive after coating more tightly sealed, ensuring the firmness and sealing of the emulsion explosive coating, preventing the emulsion explosive from leaking out, thereby improving the coating effect of the emulsion explosive.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0034] Please see Figures 1 to 9 As shown, one embodiment of the present invention is provided: an automatic film-applying device for precision temperature-controlled emulsion explosives, including a body 1, a conveyor belt 11 fixedly connected to the top of the body 1, a temperature control mechanism for automatically controlling the hot pressing temperature of the packaging film provided on the top of the body 1, and a segmented mechanism for extruding the emulsion explosives provided on the top of the conveyor belt 11.

The bottom end of the threaded column 206 is engaged with a driving part 213, which is rotatably connected to the inside of the rotating part 205. The inner wall of the machine body 1 is fixedly connected to an outer tube 215. The top of the machine body 1 is fixedly connected to a fixing plate 217. The top of the fixing plate 217 is fixedly connected to an inner tube 216. The inner wall of the inner tube 216 is fixedly connected to an injection tube 214. The outer tube 215 is sleeved on the outside of the inner tube 216. The top of the machine body 1 is fixedly connected to two mounting plates 218. The inside of the two mounting plates 218 is slidably connected to a heat-conducting plate 220. The side of the two heat-conducting plates 220 that are far apart is fixedly connected to a compression spring 219. The inside of the heat-conducting plate 220 is fixedly connected to an electric heating wire 221.

[0036] Furthermore, the segmented mechanism includes an outer housing 301, which is fixedly connected to the top of the body 1. A rotating shaft 302 is rotatably connected to the top of the outer housing 301. A second transmission belt 304 is connected between the output shaft of the motor 201 and the rotating shaft 302. Two rotating columns 306 are rotatably connected inside the outer housing 301. A transmission gear 305 is fixedly connected to the end of each rotating column 306 near the rotating shaft 302. The two transmission gears 305 are meshed. A first transmission belt 303 is connected between the rotating shaft 302 and the upper rotating column 306. Two first hydraulic rods 308 are fixedly connected to the inner wall of the outer housing 301 on the side away from the transmission gears 305. A protrusion 307 is fixedly connected to the telescopic end of the first hydraulic rod 308 and the side of the rotating column 306 near the first hydraulic rod 308. The inner wall of the outer housing 301 on the side near the transmission gears 305 is fixedly connected to... A first horizontal plate 310 is connected to the outer shell 301. A second horizontal plate 316 is fixedly connected to the inner wall of the outer shell 301 away from the first horizontal plate 310. A second hydraulic rod 311 is fixedly connected to the inside of the first horizontal plate 310. A first clamping plate 312 is fixedly connected to the end of the second hydraulic rod 311 away from the inner wall of the outer shell 301. A third hydraulic rod 313 is fixedly connected to the inside of the first clamping plate 312. A blade 314 is fixedly connected to the side of the first clamping plate 312 away from the second hydraulic rod 311. A fourth hydraulic rod 317 is fixedly connected to the inside of the second horizontal plate 316. A second clamping plate 318 is fixedly connected to the end of the fourth hydraulic rod 317 away from the inner wall of the outer shell 301. Another blade 314 is fixedly connected to the side of the second clamping plate 318 away from the fourth hydraulic rod 317. A pressing plate 309 is fixedly connected to the side of the two rotating columns 306 away from each other. A limit tube 315 is fixedly connected to the top of the first horizontal plate 310.

[0037] Furthermore, the slider 211 contacts the outer surface of the resistance wire 212, and the slider 211, resistance wire 212 and heating wire 221 are connected in series. The side of the fixing plate 217 near the mounting plate 218 is tapered, which guides the two ends of the roll film 203 so that the two ends of the roll film 203 can be smoothly attached.

[0038] Furthermore, the two heat-conducting plates 220 are attached to each other on their adjacent sides, and the end of the drive member 213 away from the threaded post 206 passes through the rotating member 205. The drive member 213 is manually rotated, which drives the threaded post 206 to rotate. The rotation of the threaded post 206 causes the support plate 207 to slide inside the rotating member 205. The slider 209 is located above the center point of the rotating member 205. When the rotating member 205 rotates, the centrifugal force received by the slider 209 will cause the slider 209 to move away from the center point of the rotating member 205.

[0039] Furthermore, there is a gap between the outer tube 215 and the inner tube 216, which is used to bend the flat roll film 203 into a cylindrical shape. The outer tube 215 is C-shaped, and there are gaps between both ends of the outer tube 215 and both sides of the fixing plate 217. The two ends of the rolled film 203, which is bent into a cylindrical shape, will pass through the gaps between the two ends of the outer tube 215 and both sides of the fixing plate 217.

[0040] Furthermore, the thickness of the extrusion plate 309 is half the distance between the two rotating columns 306, so that the rotation of the two extrusion plates 309 can extrude the emulsion explosive passing between the two rotating columns 306. The first hydraulic rod 308, the second hydraulic rod 311, the fourth hydraulic rod 317 and the third hydraulic rod 313 are all composed of a cylinder and a telescopic rod slidably connected.

[0041] Furthermore, the upper first hydraulic rod 308 is connected to the second hydraulic rod 311 and the fourth hydraulic rod 317 through a pipe, and the lower first hydraulic rod 308 is connected to the third hydraulic rod 313 through a hose. Springs are fixedly connected between the telescopic rods of the second hydraulic rod 311 and the third hydraulic rod 313 and the cylinder. The function of the springs is to reset the telescopic ends, so that the device can continuously coat the emulsion explosive.

[0042] Furthermore, the end of the blade 314 furthest from the first clamping plate 312 has an arc-shaped recess. This recess allows the film 203 to gather and embed itself into the arc-shaped recess when the blade 314 approaches and pushes it, preventing the film 203 from being incompletely cut and improving the device's performance. The two blades 314 are located on the same plane, and the film 203 can be cut by the two blades 314 interlacing. The movement of the slider 211 can adjust the initial length of the resistance wire 212 connected to the circuit, thereby controlling the initial temperature of the heat-conducting plate 220. Since different materials of film 203 require different temperatures for hot pressing, this design allows for the initial adjustment of the temperature of the heat-conducting plate 220 based on the material of the film 203.

[0043] Working principle: In the initial state, the outer end of the roll film 203 is manually pulled out and wrapped around the transmission roller 202. Then, the outer end of the roll film 203 is passed through the gap between the outer tube 215 and the inner tube 216. Since the gap between the outer tube 215 and the inner tube 216 is arc-shaped, the roll film 203 will bend as it passes through the gap, causing the two sides of the roll film 203 to bend and overlap. At this time, the roll film 203 is bent into a cylindrical shape. Then, the overlapping edges of the roll film 203 are passed through the two heat-conducting plates 220 and the two rotating columns 306 in sequence. The pressure spring 219 is in a compressed state. The extension force of the pressure spring 219 drives the heat-conducting plate 220 to squeeze the overlapping ends of the roll film 203, so that the two ends of the roll film 203 can be attached for heat pressing.

[0044] When applying the film to the emulsion explosive, the motor 201 is manually started. The output shaft of the motor 201 rotates, driving the transmission roller 202 to rotate. The rotation of the transmission roller 202 pulls the outer end of the roll film 203, thus driving the roll film 203 to rotate. The rotation of the transmission roller 202 drives the drive gear 204 to rotate, which in turn drives the rotating component 205 to rotate. The rotation of the rotating component 205 drives the slider 209 to rotate. The centrifugal force experienced by the slider 209 causes it to move away from the center point of the rotating component 205, stretching the connecting spring 208. The movement of the slider 209 causes the slider 211 to move, sliding outside the resistance wire 212. This controls the length of the resistance wire 212 connected to the circuit, thereby adjusting the current in the circuit and regulating the heating degree of the heating wire 221. The greater the centrifugal force experienced by the slider 211... The faster the rotating part 205 rotates, the shorter the length of the resistance wire 212 connected to the circuit, and the higher the temperature of the heating wire 221. Since the position of the slider 211 is automatically controlled by centrifugal force, and the magnitude of the centrifugal force on the slider 211 depends on the rotation speed of the film roll 203, the position of the slider 211 can be adjusted slightly when the rotation speed of the film roll 203 changes by a certain range, thereby precisely adjusting the temperature of the heating wire 221. This design can automatically and precisely adjust the temperature of the heating wire 221 according to the speed of the emulsion explosive film application, so that the heat-conducting plate 220 can heat-press and seal the overlapping ends of the film roll 203 at different film application speeds, avoiding the problem of the emulsion explosive leaking out due to the loose seal at the connection of the film roll 203 and the overheating of the film roll 203, preventing the waste of emulsion explosive and improving the film application effect.

[0045] The drive component 213 is manually rotated, which in turn rotates the threaded column 206. The rotation of the threaded column 206 causes the support plate 207 to slide inside the rotating component 205. The movement of the support plate 207 causes the connecting spring 208 to move, which in turn causes the slider 209 and the sliding plate 211 to move. The movement of the sliding plate 211 changes the relative position with the resistance wire 212, thereby adjusting the initial length of the resistance wire 212 connected to the circuit and controlling the initial temperature of the heat-conducting plate 220. Since different materials of the roll film 203 require different temperatures during hot pressing, this design allows for the initial adjustment of the temperature of the heat-conducting plate 220 based on the material of the roll film 203, expanding the application range of the device and improving its applicability.

[0046] The metal buckle holding the end of the emulsion explosive is manually placed in the limiting tube 315, and under the action of gravity, the buckle slides down into the groove of the first clamping plate 312;

[0047] When motor 201 starts, under the transmission action of the second transmission belt 304 and the first transmission belt 303, the output shaft of motor 201 rotates, driving the rotating shaft 302 to rotate. The rotation of the rotating shaft 302 drives the upper rotating column 306 to rotate. The rotation of the rotating column 306 drives the transmission gear 305 fixed to it to rotate. The rotation of the transmission gear 305 drives another transmission gear 305 to rotate in the opposite direction. The rotation of the transmission gear 305 drives the lower rotating column 306 to rotate, realizing the synchronous reverse rotation of the two rotating columns 306. After the overlapping ends of the roll film 203 are sealed, the emulsion explosive is manually injected into the cylindrical roll film 203 through the injection pipe 214 using external equipment. When the emulsion explosive after coating passes between the two rotating columns 306, the rotation of the two rotating columns 306 drives the extrusion plate 309 to rotate. Since the emulsion explosive is a viscous liquid, when the two extrusion plates 309 rotate to the closed state, they extrude the emulsion explosive after coating, which can squeeze the emulsion explosive in the cylindrical roll film 203 to flow, thereby segmenting the emulsion explosive. This design can prevent the emulsion explosive from being squeezed out from the cutting point when the emulsion explosive is subsequently segmented, thus preventing the emulsion explosive from being wasted. At the same time, it can prevent the blade 314 from sticking to the emulsion explosive during cutting, ensuring the effectiveness of the blade 314 and enabling the blade 314 to cut the emulsion explosive continuously.

[0048] One of the rotating columns 306 rotates, causing the fixed protrusion 307 to rotate. This rotating protrusion 307 presses against the protrusion 307 fixed to the telescopic end of the first hydraulic rod 308, causing the telescopic end of the first hydraulic rod 308 to retract into the cylinder of the first hydraulic rod 308. This increases the internal pressure of the first hydraulic rod 308. Since the first hydraulic rod 308 is connected to the second hydraulic rod 311 and the fourth hydraulic rod 317, the internal pressure of the second hydraulic rod 311 and the fourth hydraulic rod 317 also increases. Under this pressure, the telescopic ends of the second hydraulic rod 311 and the fourth hydraulic rod 317 extend out of the cylinder. The telescopic ends of the second hydraulic rod 311 and the fourth hydraulic rod 317 respectively drive the first clamping plate 312 and the second clamping plate 318 to move towards each other. 12 and the second clamping plate 318 move to drive the two blades 314 to cut the roll film 203, thus dividing the emulsion explosive. While the two blades 314 are cutting the roll film 203, another rotating column 306 rotates, which drives the protrusion 307 fixed thereto to rotate. The rotating protrusion 307 squeezes the protrusion 307 fixed to the telescopic end of another first hydraulic rod 308. The pressure in the other first hydraulic rod 308 increases, which increases the internal pressure of the third hydraulic rod 313. Under the action of pressure, the telescopic end of the third hydraulic rod 313 extends and pushes the metal buckle in the groove of the first clamping plate 312 into the groove of the second clamping plate 318. The metal buckle is squeezed and deformed and clamped at the end of the emulsion explosive after the film is applied, ensuring the firmness of the emulsion explosive film and preventing the emulsion explosive from leaking out.
