Description

Technical Field

[0001] The present invention relates to the technical field of emulsion explosive packaging, and in particular to a multi-specification emulsion explosive off-line loading and trucking system. Background Art

[0002] Emulsion explosive is a kind of water-in-oil emulsion explosive formed by uniformly dispersing micro-droplets of an oxidizer salt aqueous solution in an oil-phase continuous medium containing porous substances such as dispersed air bubbles or hollow glass microspheres with the help of an emulsifier. The finished product of industrial emulsion explosive is similar to a ham sausage, which is cylindrical. Its specifications are usually 32mm ± 1mm or 35mm ± 1mm according to the outer diameter of the cartridge. Other specifications also include an outer diameter range of 40mm to 150mm. The emulsion explosive output from the production line is first boxed, and then pallet is used to fork and stack it for loading onto the truck.

[0003] The patent document with the patent number CN2016112365072 discloses an intelligent boxing system and boxing method for emulsion explosives. The system includes a first conveyor for online transporting the finished emulsion explosive products, a second conveyor for online transporting the material boxes loaded with the finished emulsion explosive products, and also includes an installation platform. On the installation platform, there is a robot for online transferring the finished emulsion explosive products on the first conveyor into the material boxes on the second conveyor. On the installation platform, there is also a temporary storage station for storing partitions and a transfer mechanism for importing / exporting the partitions at the temporary storage station into / from the material boxes.

[0004] However, in the actual use process, the inventor found that when the emulsion explosive is off-line boxed, the products are stacked layer by layer, lacking shock absorption and buffering work, resulting in the problems that the emulsion explosive is easily squeezed and broken during boxing and transportation, and the safety is relatively low.

[0066] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0067] Embodiment 1

[0068] As Figures 1-17As shown in the figure, a multi-specification emulsion explosive offline loading and shipping system includes a conveying rack 11 and a palletizing mechanism 2 provided at the output end of the conveying rack 11. The palletizing mechanism 2 first stacks the emulsion explosives layer by layer at intervals and buffers and dampens the falling emulsion explosives during the palletizing process, and then transfers the palletized emulsion explosives as a whole into a packing box;

[0069] The palletizing mechanism 2 includes a bearing assembly 21 provided at the output end of the conveying rack 11, a rack assembly 22 provided on the bearing assembly 21, and a power assembly 23 provided on the bearing assembly 21 and used to drive the rack assembly 22 to change its state;

[0070] When the emulsion explosives need to be stacked layer by layer at intervals, the bearing assembly 21 drives the rack assembly 22 to reciprocate horizontally to continuously receive the emulsion explosives. At the same time, the power assembly 23 drives the rack assembly 22 to change its state to sequentially complete the work of receiving and storing the emulsion explosives from bottom to top layer by layer. Then, the bearing assembly 21 transfers the rack assembly 22 after palletizing the emulsion explosives into the packing box, and after the packing box is closed, it is loaded onto the vehicle.

[0071] It should be noted that for multi-specification emulsion explosives, different specifications of rack assemblies 22 are selected for packing according to the different specifications of the emulsion explosives.

[0072] Furthermore, as Figure 2 shown in the figure, the bearing assembly 21 includes:

[0073] A load-bearing plate 211, and the load-bearing plate 211 is provided on the conveying rack 11;

[0074] A blanking door 212, and the blanking door 212 is hinged on the load-bearing plate 211. A first driving unit 213 for driving the blanking door 212 to open and close automatically is provided on the load-bearing plate 211;

[0075] A moving frame 214, and the moving frame 214 is horizontally slidably provided on the load-bearing plate 211. The rack assembly 22 is placed in cooperation with the inside of the moving frame 214. A second driving unit 215 for driving the moving frame 214 to reciprocate horizontally is provided on the load-bearing plate 211;

[0076] The first driving unit 213 includes a limiting hole 2131 opened at the bottom of the blanking door 212, a limiting block 2132 slidably arranged in the limiting hole 2131, a limiting spring arranged between the limiting block 2132 and the end of the limiting hole 2131, a pull rod 2133 hinged at the bottom of the limiting block 2132, and a fourth hydraulic part 2134 arranged at the bottom of the load-bearing plate 211. The output shaft of the fourth hydraulic part 2134 is hinged to one end of the pull rod 2133 through a hinge seat;

[0077] It should be noted that the limiting spring is in a contracted state. Under the elastic force of the limiting spring, the movement of the limiting block 2132 in the limiting hole 2131 is restricted. At this time, the pull rod 2133 is vertically perpendicular to the limiting block 2132. When the blanking door 212 needs to be opened, the fourth hydraulic component 2134 contracts, first driving the pull rod 2133 to tilt relative to the limiting block 2132. The fourth hydraulic component 2134 continues to contract, generating an inclined downward pulling force on the limiting block 2132 through the pull rod 2133, thereby driving the blanking door 212 to rotate downward and open through the limiting block 2132. During the opening process of the blanking door 212, the limiting block 2132 compresses the limiting spring and moves in the limiting hole 2131 until the blanking door 212 is opened to a vertical state. Similarly, when the blanking door 212 needs to be closed, the operation process is opposite until the pull rod 2133 is vertically perpendicular and the blanking door 212 is closed to a horizontal state, thus achieving the effect of automatically opening and closing the blanking door 212;

[0078] The second driving unit 215 includes a first lead screw 2151 arranged on the bearing plate 211, a first threaded block 2152 threadedly arranged on the first lead screw 2151 and connected to the outer wall of the moving frame 214, and a first stepping motor 2153 arranged on the bearing plate 211 and used to drive the first lead screw 2151.

[0079] Further, as Figure 2 shown, the palletizing component 22 includes:

[0080] A support frame 221, several groups of the support frames 221 are sequentially connected from bottom to top by vertical rods 222, and the support frame 221 is slidably and matingly arranged inside the moving frame 214;

[0081] A strip-shaped hole 223, which is opened on opposite side walls of the support frame 221;

[0082] A strip plate 224, which is slidably arranged inside the strip-shaped hole 223, and a first elastic member 225 is arranged between one end of the strip plate 224 and one end of the strip-shaped hole 223;

[0083] A shaft rod 226, several groups of the shaft rods 226 are horizontally rotatably arranged between two opposite strip plates 224, a gear 227 is arranged on the shaft rod 226, and a rack 228 for driving the gear 227 is arranged on the support frame 221;

[0084] A swivel ring 229, two swivel rings 229 are rotatably arranged on the shaft rod 226, an arc-shaped sliding hole 2291 is opened on the swivel ring 229, a convex block 2292 slidably matched with the arc-shaped sliding hole 2291 is opened on the shaft rod 226, and a second elastic member 2293 is arranged between the convex block 2292 and the end of the arc-shaped sliding hole 2291;

[0085] It should be noted that the length of the arc-shaped sliding hole 2291 cooperates with the convex block 2292, so that the maximum opening angle between the first tooth plate 2294 and the second tooth plate 2295 is 90 degrees. The swivel ring 229 rotates on the shaft rod 226, causing the first tooth plate 2294 and the second tooth plate 2295 to overlap with misaligned teeth. The second elastic member 2293 is compressed, and the first tooth plate 2294 and the second tooth plate 2295 are kept in the state of overlapping with misaligned teeth through the clamping member 2298;

[0086] The first tooth plate 2294, and the first tooth plate 2294 is fixedly arranged between the two swivel rings 229;

[0087] The second tooth plate 2295, the second tooth plate 2295 is slidably arranged on the shaft rod 226 through a sliding ring 2296. A fixing ring 2297 is arranged on the shaft rod 226, and a third elastic member is arranged between the sliding ring 2296 and the fixing ring 2297.

[0088] It is worth mentioning that both the first tooth plate 2294 and the second tooth plate 2295 are elastic tooth plates, which have a buffering and shock-absorbing effect on the falling emulsion explosive.

[0089] It should be noted that the strip plate 224 moves a specified distance in the strip-shaped hole 223 of the support frame 221, so that the rack 228 on the support frame 221 drives the gear 227 to drive the shaft rod 226 to rotate. The shaft rod 226 drives the second tooth plate 2295 to rotate through the sliding ring 2296. At the same time, the shaft rod 226 abuts against the end of the arc-shaped sliding hole 2291 through the convex block 2292 to drive the swivel ring 229 to drive the first tooth plate 2294 to rotate synchronously with the second tooth plate 2295, so that the openings of the first tooth plate 2294 and the second tooth plate 2295 face upward, presenting a V-shaped structure, which is convenient for receiving the emulsion explosive. At the same time, the strip plate 224 drives the first tooth plate 2294 and the second tooth plate 2295 of this layer to translate a specified distance as a whole, so that the openings of the first tooth plate 2294 and the second tooth plate 2295 are exactly located in the middle of the channel formed by the upper-layer adjacent first tooth plates 2294 and second tooth plates 2295 with misaligned and overlapping teeth, which is convenient for the emulsion explosive to fall from this channel into the openings of the first tooth plate 2294 and the second tooth plate 2295 of the lower layer.

[0090] Further, as Figure 2 shown, the palletizing component 22 further includes:

[0091] The card 2298 is arranged on the first toothed plate 2294 and is used to limit the first toothed plate 2294 and the second toothed plate 2295 to maintain the state of overlapping with staggered teeth. The card 2298 includes a limiting rod 22981 arranged on the first toothed plate 2294, a claw 22982 arranged to move up and down on the limiting rod 22981, a sixth elastic member arranged between the claw 22982 and the first toothed plate 2294, and a wedge block 22983 arranged on the claw 22982;

[0092] It should be noted that the initial state of the palletizing component 22 is: all the first toothed plates 2294 and the second toothed plates 2295 are overlapped with staggered teeth in advance, and the state of overlapping with staggered teeth is ensured by the card 2298;

[0093] The baffle 2299 is arranged on the second toothed plate 2295 and is used to limit the distance between the first toothed plate 2294 and the second toothed plate 2295.

[0094] It should be noted that after the card 2298 is opened, the first toothed plate 2294 rotates and resets to the horizontal state under the drive of the second elastic member 2293, and the second toothed plate 2295 slides and resets along the shaft rod 226 under the drive of the third elastic member, so that the first toothed plate 2294 and the second toothed plate 2295 are vertically aligned with teeth. At the same time, the baffle 2299 limits the first toothed plate 2294 and the second toothed plate 2295 to maintain the state of being vertically aligned with teeth, which is convenient for the openings of the first toothed plate 2294 and the second toothed plate 2295 to turn vertically upward.

[0095] It is worth mentioning that the first toothed plate 2294 and the second toothed plate 2295 can be overlapped with staggered teeth or vertically aligned with teeth. The upper adjacent first toothed plate 2294 and second toothed plate 2295 that are overlapped with staggered teeth serve as the falling channel of the emulsion explosive, and do not interfere with the layer-by-layer and spaced palletizing work of the emulsion explosive on the palletizing component 22.

[0096] It is also worth mentioning that the lower first toothed plate 2294 and second toothed plate 2295 that are vertically aligned with teeth rotate by a specified angle under the drive of the power component 23, so that the openings of the first toothed plate 2294 and the second toothed plate 2295 turn vertically upward. The openings of the first toothed plate 2294 and the second toothed plate 2295 face directly upward, which is convenient for receiving the falling emulsion explosive, so that the first toothed plate 2294 and the second toothed plate 2295 simultaneously have a buffering and shock-absorbing effect on the falling emulsion explosive. Compared with the openings of the first toothed plate 2294 and the second toothed plate 2295 being inclined upward, that is, the first toothed plate 2294 is horizontal and the second toothed plate 2295 is vertical, only the first toothed plate 2294 has a buffering and shock-absorbing effect on the falling emulsion explosive. The openings of the first toothed plate 2294 and the second toothed plate 2295 facing directly upward have a better buffering and shock-absorbing effect on the falling emulsion explosive.

[0097] It should also be noted that after the first tooth plate 2294 and the second tooth plate 2295 receive the emulsion explosive with their openings facing directly upward, the power assembly 23 drives the openings of the first tooth plate 2294 and the second tooth plate 2295 to reset to face obliquely upward. The first tooth plate 2294 supports the emulsion explosive, separating the upper and lower layers of the emulsion explosive in the vertical direction. The second tooth plate 2295 separates the emulsion explosive of the same layer in the horizontal direction. During transportation, both the first tooth plate 2294 and the second tooth plate 2295 have a shock-absorbing effect on the emulsion explosive.

[0098] Further, as Figure 2 shown, the power assembly 23 includes:

[0099] An installation frame 231, which is arranged outside the moving frame 214 in a lifting manner through a third driving unit 232. A first hydraulic component 233 for driving the horizontal movement of the installation frame 231 is arranged on the third driving unit 232;

[0100] The third driving unit 232 includes two groups of second lead screws 2321 symmetrically arranged on the opposite outer side walls of the moving frame 214, second threaded blocks 2322 threadedly arranged on the second lead screws 2321, and a second stepping motor 2323 arranged on the outer wall of the moving frame 214 and used for driving the second lead screw 2321. The first hydraulic component 233 is installed on the second threaded block 2322;

[0101] A power plate 234, which is horizontally slidably arranged on the installation frame 231. A number of groups of insertion rods 235 are arranged on the power plate 234. Jacks 236 matching the insertion rods 235 are arranged on the strip plate 224. A second hydraulic component 237 for driving the horizontal movement of the power plate 234 is arranged on the installation frame 231;

[0102] An ear plate, which is arranged on the power plate 234. A third hydraulic component 238 is arranged on the ear plate. A transmission plate 239 is arranged on the output shaft of the third hydraulic component 238. A number of groups of ramming rods 2391 are arranged on the transmission plate 239, and the ramming rods 2391 are used to open the clamping member 2298.

[0103] It should be noted that after the ramming rod 2391 enters the interior of the moving frame 214 and continues to advance along the lower inclined surface of the wedge-shaped block 22983 of the clamping member 2298, the ramming rod 2391 forces the wedge-shaped block 22983 to drive the claw 22982 to rise, opening the clamping member 2298, thereby opening the first tooth plate 2294 and the second tooth plate 2295 that are overlapped with misaligned teeth.

[0104] It should be noted that the emulsion explosive intermittently falls at a fixed position at the output end of the conveying rack 11 and separates from the production line. The bearing assembly 21 drives the palletizing rack assembly 22 to move horizontally in an intermittent reciprocating manner through the moving frame 214, so that the emulsion explosive sequentially falls through the falling channel formed by the adjacent first tooth plate 2294 and the second tooth plate 2295 with staggered teeth overlapping, enabling the same number of emulsion explosives to be palletized on each layer, and the blanking is accurate.

[0105] In this embodiment, through the cooperation of the palletizing rack assembly 22 and the power assembly 23, on the one hand, two elastic tooth plates can be sequentially unfolded layer by layer from bottom to top, and the opening directions of the two elastic tooth plates can be changed, which is convenient for receiving the emulsion explosive for layer-by-layer interval palletizing, slowing down the impact force of the falling emulsion explosive, preventing the emulsion explosive from being knocked and damaged, and the blanking of the emulsion explosive is accurate, ensuring that the number of layers of palletizing is the same; on the other hand, the emulsion explosive can be palletized and boxed layer by layer at intervals, preventing the emulsion explosive from being stacked and squeezed and broken, having a good shock absorption and buffering effect, high safety, and being beneficial to the transportation and storage of the emulsion explosive.

[0106] Specifically, the rack assembly 22 with all the first toothed plates 2294 and second toothed plates 2295 overlapped with staggered teeth in advance is placed in the moving frame 214. The vertical rods 222 at the bottom of the rack assembly 22 are in sliding fit with the upper surface of the load-bearing plate 211. The emulsion explosive intermittently falls at a fixed position at the output end of the conveying rack 11. The second stepping motor 2323 of the third driving unit 232 drives the power plate 234 to intermittently lift and lower the insertion rod 235 through the second lead screw 2321 and the second threaded block 2322, so that the insertion rod 235 starts from the support frame 221 at the lowest layer of the rack assembly 22. The first hydraulic component 233 drives the mounting frame 231 to move the power plate 234 closer to the rack assembly 22, so that the insertion rod 235 on the power plate 234 is inserted into the insertion hole 236 of the strip plate 224. Then, the third hydraulic component 238 drives the transmission plate 239 to move the ramming rod 2391 closer to the clamping part 2298, so that the ramming rod 2391 advances along the inclined plane of the wedge-shaped block 22983 of the clamping part 2298. The ramming rod 2391 forces the wedge-shaped block 22983 to drive the claw 22982 to rise, opening the clamping part 2298, thereby opening the first toothed plate 2294 and the second toothed plate 2295 with staggered teeth overlapped. The first toothed plate 2294 unfolds to a horizontal state. At the same time, the second toothed plate 2295 slides and resets along the shaft rod 226 under the drive of the third elastic member, so that the first toothed plate 2294 and the second toothed plate 2295 are vertically aligned. The baffle 2299 restricts the first toothed plate 2294 and the second toothed plate 2295 to maintain the vertically aligned state. Then, the third hydraulic component 238 drives the transmission plate 239 to drive the ramming rod 2391 to reset. Then, the second hydraulic component 237 drives the power plate 234 to move horizontally, so that the power plate 234 drives the strip plate 224 to move in the strip-shaped hole 223 through the insertion rod 235. The rack 228 on the support frame 221 drives the gear 227 to drive the shaft rod 226 to rotate. The shaft rod 226 drives the second toothed plate 2295 to rotate through the slip ring 2296. At the same time, the shaft rod 226 drives the first toothed plate 2294 to rotate synchronously with the second toothed plate 2295 through the convex block 2292 against the end of the arc-shaped sliding hole 2291 to drive the rotating ring 229, so that the openings of the first toothed plate 2294 and the second toothed plate 2295 face upward, presenting a V-shaped structure, and the openings of the first toothed plate 2294 and the second toothed plate 2295 are exactly in the middle of the channel formed by the upper adjacent two first toothed plates 2294 and second toothed plates 2295 with staggered teeth overlapped. The emulsion explosive falls from this channel at a fixed position at the output end of the conveying rack 11 into the openings of the first toothed plate 2294 and the second toothed plate 2295 at the lower layer. Then, the first stepping motor 2153 of the second driving unit 215 drives the moving frame 214 to drive the rack assembly 22 to intermittently reciprocate horizontally on the load-bearing plate 211 through the first lead screw 2151 and the first threaded block 2152, so that the emulsion explosive sequentially passes through the middle of the channels formed by each adjacent two first toothed plates 2294 and second toothed plates 2295 with staggered teeth overlapped, and sequentially completes the material receiving and stacking work at the lower layer. Then,The first hydraulic component 233 drives the mounting frame 231 to reset with the power plate 234, causing the insertion rod 235 on the power plate 234 to disengage from the insertion hole 236 of the strip plate 224. The strip plate 224 resets under the drive of the first elastic member 225, and all the first toothed plates 2294 and second toothed plates 2295 on this layer translate and reset. At the same time, the rack 228 on the support frame 221 drives the gear 227 to rotate reversely with the shaft rod 226 to reset, and the first toothed plate 2294 and the second toothed plate 2295 rotate reversely to reset. The first toothed plate 2294 and the second toothed plate 2295 separate each emulsion explosive in the vertical and horizontal directions. The third drive unit 232 drives the insertion rod 235 to rise by a specified height to stack emulsion explosives on the first toothed plate 2294 and the second toothed plate 2295 of the upper layer until stacking reaches the top layer. Then, the second drive unit 215 drives the moving frame 214 to move the stacking frame assembly 22 to the position of the blanking door 212. The first drive unit 213 opens the blanking door 212. At this time, the insertion rod 235 has not yet disengaged from the insertion hole 236 of the top strip plate 224, so the stacking frame assembly 22 will not fall immediately. Finally, the third drive unit 232 drives the insertion rod 235 to gradually lower the stacking frame assembly 22 through the insertion hole 236 of the strip plate 224 until the stacked stacking frame assembly 22 descends into the packaging box, and the insertion hole 236 disengages from the insertion hole 236 of the strip plate 224, reducing the height at which the stacking frame assembly 22 falls into the packaging box. The packing and blanking work of the stacking frame assembly 22 is also relatively gentle, avoiding collision damage.

[0107] Embodiment 2

[0108] As Figures 1-4 shown, where the same or corresponding components as in Embodiment 1 are denoted by the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The differences between this Embodiment 2 and Embodiment 1 are as follows:

[0109] Further, as Figures 1-4 shown, it further includes a conveying mechanism 1 provided on the conveying frame 11. The conveying mechanism 1 includes a roller conveying unit 12 provided on the conveying frame 11 and a guiding unit 13 provided on the conveying frame 11 and located at the output end of the roller conveying unit 12. The conveying mechanism 1 sequentially conveys the emulsion explosives distributed at intervals to the stacking mechanism 2;

[0110] The guiding unit 13 includes:

[0111] A guiding channel 131, which is inclinedly arranged on the conveying frame 11;

[0112] A buffer plate 132, which is elastically hinged to the output end of the guiding channel 131 through a fifth elastic member 133 and is used to guide the emulsion explosive to fall vertically.

[0113] It should be noted that the structure and function of the roller conveying unit 12 are both prior arts and will not be elaborated herein.

[0114] In this embodiment, through the provided material guiding unit 13, on the one hand, it can change the falling direction of the emulsion explosive, slow down the horizontal speed of the emulsion explosive during the falling process, ensure that the emulsion explosive falls vertically, and facilitate the accurate falling of the emulsion explosive into the channel formed by the first tooth plate 2294 and the second tooth plate 2295 with overlapping staggered teeth adjacent to each other; on the other hand, the buffer plate 132 can slow down the impact force of the falling emulsion explosive, avoid the emulsion explosive from being damaged by collision, reduce the speed of the emulsion explosive descending to the above channel, and ensure that the emulsion explosive falls more gently.

[0115] Specifically, the roller conveying unit 12 sequentially conveys the emulsion explosives distributed at intervals to the palletizing mechanism 2, and the emulsion explosives fall onto the buffer plate 132 through the material guiding channel 131. The buffer plate 132 slows down the falling speed of the emulsion explosives and changes the vertical falling direction of the emulsion explosives.

[0116] Embodiment Three

[0117] As Figures 1-2 and Figures 18-19 shown, the same or corresponding components as those in Embodiment One adopt the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below. The differences between this Embodiment Three and Embodiment One are as follows:

[0118] Further, as Figures 1-2 and Figures 18-19 shown, it further includes a blanking mechanism 3 provided on the palletizing mechanism 2. The blanking mechanism 3 replenishes new pallet components 22 to the bearing assembly 21. The blanking mechanism 3 includes:

[0119] A blanking box 31, the blanking box 31 is arranged above the load-bearing plate 211 through a bracket, and several groups of the pallet components 22 are sequentially placed vertically inside the blanking box 31;

[0120] Operation strip holes 32, the two operation strip holes 32 are respectively opened on the opposite side walls of the blanking box 31;

[0121] A transmission assembly 33, the transmission assembly 33 is arranged on the outer wall of the blanking box 31 and is used to drive the pallet components 22 inside the blanking box 31 to automatically drop one by one;

[0122] The transmission assembly 33 includes:

[0123] Expansion frames 331, the two expansion frames 331 are respectively arranged on the opposite outer walls of the blanking box 31;

[0124] The conveyor belt 332 is rotatably arranged on the outward expansion frame 331, and a third stepping motor 333 for driving the conveyor belt 332 to operate is arranged on the outward expansion frame 331;

[0125] The positioning rods 334 are arranged through and slidably on the conveyor belt 332 in several groups. A fourth elastic member 335 is arranged between one end of the positioning rod 334 and the conveyor belt 332, and the other end of the positioning rod 334 is matched with the jack 236 on the strip plate 224;

[0126] The limit track 336 is arranged on the outward expansion frame 331 and is used to drive the other end of the positioning rod 334 to enter the inside of the jack 236 of the strip plate 224.

[0127] In this embodiment, through the arranged blanking mechanism 3, on the one hand, it can automatically control the intermittent falling of a single palletizing component 22 to the bearing component 21, which is convenient for the automatic feeding work of the bearing component 21 and ensures that the palletizing and boxing work of emulsion explosive can be continuously implemented; on the other hand, it can automatically control the slow falling of a single palletizing component 22 to the bearing component 21, slow down the impact force when the palletizing component 22 descends to the bearing component 21, avoid the palletizing component 22 from being damaged by bumping, and improve the service life of the palletizing component 22.

[0128] Specifically, several groups of palletizing components 22 are vertically arranged in the blanking box 31. After the moving frame 214 of the bearing component 21 stops at the position directly below the blanking box 31, the third stepping motor 333 of the transmission component 33 drives the conveyor belt 332 to work, so that the positioning rods 334 on both sides of the blanking box 31 slowly descend. During the descending process, the limit track 336 drives the positioning rods 334 to sequentially insert into the jacks 236 of the two palletizing components 22 in the lower position. When the first palletizing component 22 in the lower position descends to the moving frame 214, the positioning rod 334 disengages from the limit track 336 and sequentially disengages from the jacks 236 of each strip plate 224 from bottom to top until the first palletizing component 22 in the lower position descends into the moving frame 214. At this time, the conveyor belt 332 stops working, and the second palletizing component 22 in the lower position stops descending under the limitation of the jack 236, thus completing the intermittent single blanking work.

[0129] Embodiment 4

[0130] As Figures 1-2 shown, the same or corresponding components as those in Embodiment 1 adopt the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this Embodiment 4 and Embodiment 1 is that:

The packing mechanism 4 includes a conveyor belt 41 arranged below the discharge door 212. The packing boxes are placed at intervals on the conveyor belt 41. The packing mechanism 4 sequentially conveys the packing boxes to the position below the bearing assembly 21.

[0132] It should be noted that the conveyor belt 41 intermittently conveys the packing boxes to the position below the discharge door 212. After the pallet rack assembly 22 after palletizing the emulsion explosives descends into the packing box, the conveyor belt 41 continues to convey the packing box to the next process for packaging, and finally for loading.

[0133] Working process:

[0134] The conveying mechanism 1 sequentially conveys the emulsion explosives distributed at intervals to the palletizing mechanism 2. The bearing assembly 21 drives the pallet rack assembly 22 to reciprocate horizontally to receive the emulsion explosives. The power assembly 23 drives the pallet rack assembly 22 to change states to sequentially complete the work of receiving and storing the emulsion explosives layer by layer from bottom to top. The packing mechanism 4 sequentially conveys the packing boxes to the position below the bearing assembly 21. The bearing assembly 21 transfers the pallet rack assembly 22 after palletizing the emulsion explosives into the packing box. The blanking mechanism 3 replenishes a new pallet rack assembly 22 onto the bearing assembly 21.
