Description

Technical Field

[0001] The invention relates to the technical field of emulsion explosive unpacking, in particular to an unpacking and anti-blocking device for emulsion explosive that can be packaged. Background Art

[0002] Emulsion explosives are a type of water-containing explosives. With the help of emulsifiers, droplets of aqueous oxidant salt solutions are evenly dispersed in an oil-phase continuous medium containing porous substances such as dispersed bubbles or hollow glass microspheres, forming an oil-in-water emulsion explosive.

[0003] After searching, the patent of "opening and anti-blocking device for emulsion explosives" with the existing announcement number "CN115214954B" is as follows: the medicine box opening mechanism includes a box body with open upper and lower ends and an opening assembly, the box body is provided with a baffle for placing the medicine box, the opening assembly is arranged in the box body for opening the bottom of the medicine box, the baffle can be driven to open to make the emulsion explosive fall out of the box body, the explosive anti-blocking mechanism includes a material storage assembly and a feeding assembly for dispersing and providing the emulsion explosive one by one, the material storage assembly includes a medicine storage bin and a plurality of anti-blocking rollers horizontally arranged in the medicine storage bin, the medicine storage bin is located below the box body and is connected to the box body, the emulsion explosive enters the feeding assembly through the medicine storage bin, the emulsion explosive can be automatically opened during use, and at the same time, during the collection and packaging process of the emulsion explosive after opening the box, the emulsion explosive can be prevented from blocking the equipment, and the collection and packaging efficiency is higher.

[0004] However, the above patents still have shortcomings in actual use:

[0005] 1. Since the carton containing the emulsion explosive is placed into the box with the seal facing downward, and the middle of the carton containing the emulsion explosive is sealed by tape, the middle of the sealed carton will fall down under the gravity of the emulsion explosive. However, the patent lacks a device to support the middle of the carton. Therefore, even if the blade is only one carton thick, when the blade enters the carton to cut the carton seal, the blade may still scratch the emulsion explosive in the carton.

[0006] 2. In addition, after the carton containing emulsion explosives is opened, it is necessary to manually take out the carton, which is quite troublesome. Due to the squeezing and friction between the emulsion explosives in the carton, the single taking action cannot make the emulsion explosives in the carton be discharged smoothly under the action of gravity, and the emulsion explosives may be stuck in the carton. Summary of the invention

[0007] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a box opening and anti-blocking device for emulsion explosives that can be packaged.

[0018] The present invention has the following beneficial effects:

[0019] 1. By setting up the unpacking mechanism and the driving mechanism, the driving motor rotates in the opposite direction, driving the blade to move to unpack, and the bearing plate also slides back and forth to support the middle seal of the carton, thereby preventing the middle seal of the carton from falling under the gravity of the emulsion explosive, thereby preventing the blade from scratching the emulsion explosive when unpacking;

[0020] 2. By setting up an anti-adhesion mechanism, the blade can move horizontally to squeeze the cardboard at the opening of the carton to both sides when opening the carton, thereby breaking the adhesion of the carton or preventing the cardboard at the opening from adhering due to glue, thereby further optimizing the opening effect;

[0021] 3. By setting up a pick-and-place mechanism, the driving motor rotates in the forward direction, driving the reciprocating screw to rotate, and then driving the slider to slide upward first, driving the fixed frame to move upward, and then driving the clamped carton to move upward. The emulsion explosive in the carton will fall from the opening of the carton under the action of gravity and fall into the unpacking bin.

[0022] 4. By setting the first arc-shaped protrusion and the second arc-shaped protrusion, when the fixed frame moves upward, the multiple second arc-shaped protrusions will move synchronously, and the second arc-shaped protrusions will be staggered and abutted against the multiple first arc-shaped protrusions during the movement. In cooperation with the third spring, the cross bar will slide back and forth in a sealed manner, thereby driving the fixed frame to move back and forth, and driving the clamped carton to shake back and forth horizontally, thereby facilitating the rapid discharge of the emulsion explosive in the carton, avoiding the emulsion explosive in the carton from being stuck in the carton due to mutual squeezing and unable to be discharged, and improving the discharge effect of the emulsion explosive;

[0023] 5. By setting up an anti-blocking mechanism, the emulsion explosive that falls into the unpacking bin will fall onto the anti-blocking plate. Since the anti-blocking plate is set at an angle, the emulsion explosive will roll down, and the gap between the anti-blocking plate and the inner wall of the unpacking bin only allows a single emulsion explosive to pass through, so the emulsion explosives will fall one by one and then be discharged from the unpacking bin individually for repackaging. In addition, when the cross bar reciprocates and slides in a sealed manner, the air in the fourth slot will be repeatedly squeezed and drawn out of the fifth slot, thereby driving the second support rod to slide up and down repeatedly. In conjunction with the torsion spring, the anti-blocking plates on both sides will swing up and down alternately, thereby shaking the emulsion explosive on the anti-blocking plate, thereby increasing the mobility of the emulsion explosive and preventing a single emulsion explosive from being stuck between the anti-blocking plate and the inner wall of the unpacking bin, causing blockage, and making it impossible for the emulsion explosive to be discharged individually.

[0038] It should be noted that the upper end of the carrying plate 18 and the upper end of the cross block 4 are located at the same level.

[0039] A pick-and-place mechanism is installed in the unpacking bin 1, and the pick-and-place mechanism includes two third grooves 19 symmetrically opened on the inner wall of the unpacking bin 1, two sliders 20 are slidably connected to the inner wall of the two third grooves 19, and the side walls of the two sliders 20 close to each other are opened with fourth grooves 21, and the inner wall of the fourth groove 21 is sealed and slidably connected with a cross bar 22, and a fixed frame 23 is fixedly connected between the cross bars 22, and two electric push rods 24 are symmetrically fixedly connected to the side wall of the fixed frame 23, and the movable ends of the two electric push rods 24 penetrate the inner wall of the fixed frame 23 and are fixedly connected to a fixed plate 25.

[0040] A driving mechanism is installed in the third groove 19, and the driving mechanism includes a reciprocating screw 26 rotatably connected to the inner wall of one of the third grooves 19, and the side wall of the reciprocating screw 26 is threadedly connected to the slider 20. A groove 51 cooperating with the reciprocating screw 26 is provided on the side wall of one of the bearing plates 18, and a slide bar 27 is fixedly connected to the inner wall of the other third groove 19, and the side wall of the slide bar 27 is slidably connected to the slider 20. An installation groove 28 is provided on the inner wall of the unpacking warehouse 1, and a motor 29 is fixedly connected to the bottom of the installation groove 28. A first one-way bearing 30 is fixedly connected to the output end of the motor 29, and a second one-way bearing 31 is fixedly connected to the other end of the first one-way bearing 30. The lower end of the reciprocating screw 26 extends into the installation groove 28 and is fixedly connected to the second one-way bearing 31.

[0041] The driving mechanism also includes a worm 32 rotatably connected to the upper end of the T-block 9. A cavity 34 is opened in the T-block 9, and the cavity 34 is connected to the mounting groove 28. A driving wheel 33 is fixedly connected to the side wall of the first one-way bearing 30. The lower end of the worm 32 extends into the cavity 34 and is fixedly connected to a driven wheel 35. The driving wheel 33 is connected to the driven wheel 35 through a synchronous belt.

[0042] It should be noted that the first one-way bearing 30 and the second one-way bearing 31 are arranged in opposite directions, the output end of the motor 29 is fixedly connected to the inner ring of the first one-way bearing 30, the outer ring of the second one-way bearing 31 is fixedly connected to the inner ring of the first one-way bearing 30, and the reciprocating screw 26 is fixedly connected to the inner ring of the second one-way bearing 31. When the drive motor 29 rotates forward, it can drive the reciprocating screw 26 to rotate, and the driving wheel 33 does not rotate at this time. When the drive motor 29 rotates reversely, it can drive the driving wheel 33 to rotate, and the reciprocating screw 26 does not rotate at this time.

[0043] Furthermore, the driving motor 29 rotates in the opposite direction, and the motor 29 drives the driving wheel 33 to rotate through the first one-way bearing 30, thereby driving the worm 32 to rotate, and driving the worm wheel 15 to rotate. The worm wheel 15 drives the limiting rod 16 to rotate eccentrically. Due to the restriction of the limiting groove 17, the driving rod 11 will swing back and forth, and then the driving rod 11 will drive the cross block 4 to slide back and forth on the inner wall of the cross groove 3 through the connecting shaft 13 and the connecting rod 12, thereby driving the blade 8 to move back and forth, unsealing the carton containing emulsion explosives, and cutting off the tape at the sealing of the carton. In the process of reciprocating sliding of the cross block 4, the bearing plate 18 will also slide back and forth to support the middle sealing part of the carton, thereby preventing the middle sealing part of the carton from falling under the gravity of the emulsion explosive, thereby preventing the blade 8 from scratching the emulsion explosive when opening the box.

[0044] It is worth mentioning that the driving motor 29 rotates forward, driving the reciprocating screw 26 to rotate, and then driving the slider 20 to slide upward first, driving the fixed frame 23 to move upward, and then driving the clamped carton to move upward. The emulsion explosive in the carton will fall from the opening of the carton under the action of gravity and fall into the unpacking bin 1. There is no need for workers to manually take out the carton, saving time and effort.

[0045] A plurality of first arc-shaped protrusions 36 are fixedly connected to the inner wall of the unpacking bin 1, and the first arc-shaped protrusions 36 on both sides are staggered with each other, a second arc-shaped protrusion 37 cooperating with the first arc-shaped protrusion 36 is fixedly connected to the side wall of the fixed frame 23, a third spring 49 is fixedly connected to the inner wall of the fourth groove 21, and the other end of the third spring 49 is fixedly connected to the cross bar 22.

[0046] Furthermore, during the upward movement of the fixed frame 23, the multiple second arc-shaped protrusions 37 will move synchronously. During the movement, the second arc-shaped protrusions 37 will be staggered and abutted against the multiple first arc-shaped protrusions 36. In conjunction with the third spring 49, the cross bar 22 will slide back and forth in a sealed manner, thereby driving the fixed frame 23 to move back and forth, and driving the clamped carton to shake horizontally back and forth, thereby facilitating the rapid discharge of the emulsion explosive in the carton, and preventing the emulsion explosive in the carton from being stuck in the carton due to mutual squeezing and unable to be discharged. If the emulsion explosive is not completely discharged in a single lift, the motor 29 can be continuously driven to rotate in the forward direction, driving the carton to move back and forth multiple times until the emulsion explosive in the carton is completely discharged.

[0047] An anti-blocking mechanism is installed on the fixed frame 2, and the anti-blocking mechanism includes four horizontal plates 41 fixedly connected to the side walls of the fixed frame 2, wherein the side walls of two horizontal plates 41 located on the same side close to each other are connected to a rotating shaft 42 for rotation together, and the side wall of the rotating shaft 42 is fixedly connected to an anti-blocking plate 43, and the side wall of the rotating shaft 42 is symmetrically sleeved with two torsion springs 44, and the two ends of the torsion spring 44 are respectively fixedly connected to the side wall of the horizontal plate 41 and the side wall of the anti-blocking plate 43.

[0048] The anti-blocking mechanism also includes two first support rods 45 symmetrically fixedly connected to the upper end of the T-block 9, a fifth groove 46 is opened at the upper end of the first support rod 45, a second support rod 47 is sealingly and slidably connected to the inner wall of the fifth groove 46, the upper end of the second support rod 47 slides against the lower end of the anti-blocking plate 43, a second spring 48 is fixedly connected to the bottom of the fifth groove 46, the upper end of the second spring 48 is fixedly connected to the second support rod 47, the fifth groove 46 is connected to the fourth groove 21 through a second connecting pipe 50, and the second connecting pipe 50 is made of a hose.

[0049] It should be noted that, when the second support rod 47 slides upward and pushes the anti-blocking plate 43 to rotate upward to the maximum position, the side wall of the anti-blocking plate 43 abuts against the inner wall of the unpacking bin 1, making it impossible for the emulsion explosive to pass through. When the second support rod 47 slides downward to the lowest position, the anti-blocking plate 43 rotates downward to the lowest position under the action of the torsion spring 44. At this time, the gap between the anti-blocking plate 43 and the inner wall of the unpacking bin 1 only allows a single emulsion explosive to pass through.

[0050] Furthermore, the emulsion explosive dropped into the unpacking bin 1 will fall onto the anti-blocking plate 43. Since the anti-blocking plate 43 is tilted, the emulsion explosive will roll downward, and the gap between the anti-blocking plate 43 and the inner wall of the unpacking bin 1 only allows a single emulsion explosive to pass through, so the emulsion explosive will fall one by one and then be discharged from the unpacking bin 1 individually for packaging. In addition, when the cross bar 22 slides back and forth in a sealed manner, the air in the fourth groove 21 will be repeatedly squeezed and drawn out of the fifth groove 46, thereby driving the second support rod 47 to slide up and down repeatedly. In conjunction with the torsion spring 44, the anti-blocking plates 43 on both sides will swing up and down alternately, thereby shaking the emulsion explosive on the anti-blocking plate 43, thereby increasing the mobility of the emulsion explosive and preventing a single emulsion explosive from being stuck between the anti-blocking plate 43 and the inner wall of the unpacking bin 1, causing blockage, and making it impossible for the emulsion explosive to be discharged individually.

[0051] An anti-adhesion mechanism is installed in the limiting groove 17, and the anti-adhesion mechanism includes an airbag 39 fixedly connected to the inner wall of the limiting groove 17, and the other end of the airbag 39 is fixedly connected to the side wall of the limiting rod 16. The airbag 39 is connected to the second groove 6 through a first connecting pipe 40, and the first connecting pipe 40 is made of a hose. A first spring 38 is fixedly connected between the inner wall of the second groove 6 and the fixed rod 7.

[0052] Furthermore, if the thickness of the carton is uneven, the blade 8 cannot completely cut the carton when opening, and there will be a little adhesion, or after the blade 8 has opened the carton multiple times, part of the glue on the tape will adhere to the side wall of the blade 8, so when the blade 8 is opening, part of the glue may adhere to the opening of the carton, which will cause adhesion at the opening of the carton, which may cause the carton to be not opened properly, and the driving rod 11 will repeatedly squeeze and stretch the airbag 39 when swinging, and then the airbag 39 will repeatedly squeeze and extract air into and out of the second groove 6 through the first connecting tube 40, thereby driving the fixed rod 7 to slide back and forth, and driving the blade 8 to move back and forth a short distance, and then the blade 8 can move horizontally when opening the carton to squeeze the cardboard at the opening of the carton to both sides, thereby breaking the adhesion of the carton or avoiding the cardboard at the opening due to glue, thereby achieving the effect of further optimizing the unpacking.

[0053] In the present invention, the carton containing the emulsion explosive is placed with its opening downward into the fixing frame 23, and then the electric push rod 24 is driven to extend, driving the fixing plates 25 to approach each other, clamping and fixing the carton, and then the motor 29 is driven to rotate in the opposite direction. The motor 29 drives the driving wheel 33 to rotate through the first one-way bearing 30, and then drives the worm 32 to rotate, driving the worm wheel 15 to rotate, and the worm wheel 15 drives the limiting rod 16 to rotate eccentrically. Due to the limitation of the limiting groove 17, the driving rod 11 will swing back and forth, and the The driving rod 11 will drive the cross block 4 to slide back and forth on the inner wall of the cross groove 3 through the connecting shaft 13 and the connecting rod 12, thereby driving the blade 8 to move back and forth, unsealing the carton containing the emulsion explosive and cutting off the tape at the sealing portion of the carton. In the process of reciprocating sliding of the cross block 4, the bearing plate 18 will also slide back and forth to support the middle sealing portion of the carton, thereby preventing the middle sealing portion of the carton from falling under the gravity of the emulsion explosive, thereby preventing the blade 8 from scratching the emulsion explosive when opening the carton.

[0054] In addition, if the thickness of the carton is uneven, the blade 8 cannot completely cut the carton when opening, and there will be a little adhesion, or after the blade 8 has opened the carton many times, part of the glue on the tape will adhere to the side wall of the blade 8, so when the blade 8 opens the carton, part of the glue may adhere to the opening of the carton, which will cause adhesion at the opening of the carton, which may cause the carton to be not opened properly, and the driving rod 11 will repeatedly squeeze and stretch the airbag 39 when swinging, and then the airbag 39 will repeatedly squeeze and extract air into and out of the second groove 6 through the first connecting tube 40, thereby driving the fixed rod 7 to slide back and forth, and driving the blade 8 to move back and forth a short distance, and then the blade 8 can move horizontally when opening the carton to squeeze the cardboard at the opening of the carton to both sides, thereby breaking the adhesion of the carton or avoiding the cardboard at the opening due to glue, thereby achieving the effect of further optimizing the unpacking.

[0055] After the unpacking is completed, the driving motor 29 rotates forward, driving the reciprocating screw 26 to rotate, and then driving the slider 20 to slide upward first, driving the fixed frame 23 to move upward, and then driving the clamped carton to move upward. The emulsion explosive in the carton will fall from the opening of the carton under the action of gravity and fall into the unpacking bin 1. There is no need for workers to manually take out the carton, which saves time and effort. In the process of the fixed frame 23 moving upward, the multiple second arc-shaped protrusions 37 will move synchronously, and the second arc-shaped protrusions 37 will move with the multiple second arc-shaped protrusions 37 during the movement. The first arc-shaped protrusions 36 are staggered and abutted against each other, and cooperate with the third spring 49, which will make the cross bar 22 slide back and forth in a sealed manner, thereby driving the fixed frame 23 to move back and forth, and driving the clamped carton to shake horizontally back and forth, so as to facilitate the rapid discharge of the emulsion explosive in the carton, and avoid the emulsion explosive in the carton being stuck in the carton due to mutual squeezing and unable to be discharged. If the emulsion explosive is not completely discharged in a single lifting, the motor 29 can be continuously driven to rotate in the forward direction, driving the carton to move back and forth up and down multiple times until the emulsion explosive in the carton is completely discharged.

[0056] The emulsion explosive that falls into the unpacking bin 1 will fall onto the anti-blocking plate 43. Since the anti-blocking plate 43 is tilted, the emulsion explosive will roll downward, and the gap between the anti-blocking plate 43 and the inner wall of the unpacking bin 1 only allows a single emulsion explosive to pass through, so the emulsion explosives will fall one by one and then be discharged individually from the unpacking bin 1 for repackaging. In addition, when the cross bar 22 slides back and forth in a sealed manner, the air in the fourth groove 21 will be repeatedly squeezed and drawn out of the fifth groove 46, thereby driving the second support rod 47 to slide up and down repeatedly. In conjunction with the torsion spring 44, the anti-blocking plates 43 on both sides will swing up and down alternately, thereby shaking the emulsion explosive on the anti-blocking plate 43, thereby increasing the mobility of the emulsion explosive and preventing a single emulsion explosive from being stuck between the anti-blocking plate 43 and the inner wall of the unpacking bin 1, causing blockage, and making it impossible for the emulsion explosive to be discharged individually.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
