Description

Technical Field

[0001] The present invention relates to the technical field of air-drying and conveying of emulsion explosives, and particularly to a blowing and conveying device for the production of emulsion explosives. Background Art

[0002] As a highly safe industrial explosive, emulsion explosives need to go through multiple processes such as mixing, filling, and packaging during production. During the production process, the material rolls need to be transported into a water tank for cooling, and then the cooled material rolls are dried by a drying device. However, wrinkles are likely to occur at both ends (i.e., the sealed ends) of the packaged columnar explosives, especially when the diameter is large or the sealing pressure is uneven, the depth of the wrinkles increases.

[0003] For example, the emulsion explosive production cartridge cooling and conveying system with the application number CN202122214305.0 includes a base, a water tank is fixed on the top of the base, a longitudinal conveyor belt is arranged inside the water tank, a first mesh plate is uniformly fixed on the outside of the longitudinal conveyor belt, and a refrigeration chamber is opened at the bottom of the water tank. The arrangement of the longitudinal conveyor belt inside the water tank can convey the cartridges downward and pick them up during the conveying process through the first mesh plate inclined on the longitudinal conveyor belt.

[0004] For example, a conveying device with a drying function for emulsion explosive production with the application number CN202410848345.6; includes a plate platform, a rotating structure, an axial rotating arm, a controller, and an automatic clamping structure for clamping a container filled with emulsion explosives, and also includes a drying structure. The drying structure includes at least one electric blower. The electric blower includes a base and an electric blower main body fixed on the base. The base is arranged on the vertical end of the inclined member located at the lower surface of the circular disk, and the blowing port of the electric blower main body is arranged towards the longitudinal central axis direction of the circular disk; or the electric blower is arranged at the lower surface of the circular disk; the control end of the electric blower main body is electrically connected to the controller after being wound around the automatic clamping structure through an electric blower transmission line. By setting a drying structure for air-drying the emulsion explosives in the clamped container, it has a drying function.

[0005] There are some problems in the use of the above technical solutions. It is difficult to air-dry the wrinkled positions, resulting in a poor air-drying effect, and it is not convenient to adjust according to the size of the explosives, and the wind speed during air-drying cannot be dynamically adjusted.

[0006] Therefore, it is very necessary to invent a blowing and conveying device for the production of emulsion explosives to solve the above problems. Summary of the Invention

[0011] Preferably, the switching control part further includes: a second air outlet pipe, which is communicated outside the switching sleeve and passes through the side wall of the wind cylinder; a pneumatic extension part, which is communicated with the second air outlet pipe and is fixedly connected to the clamping mounting frame and the traction plate at both ends respectively, and is used to push the traction plate to slide relative to the clamping mounting frame; by adjusting the three-way air inlet pipe to be communicated with the second air outlet pipe through the extrusion assembly, the pneumatic extension part is compressed and extended to adjust the position of the traction plate; when the switching rod moves, the first air outlet pipe is communicated with the second air outlet pipe to reset the blocking part.

[0016] Preferably, a plurality of the linear driving portions are arranged along the extending direction of the lower conveyor belt.

[0017] The technical effects and advantages of the present invention: 1. By setting the clamping assembly and the air-drying assembly, the present invention effectively achieves the purpose of facilitating the air-drying of the wrinkled position. During use, the product is clamped by the clamping rods, and the rotation of the upper conveyor belt and the lower conveyor belt is stopped. At this time, the clamping assembly presses the end of the product, so that the wrinkles at the end of the product are stretched open, reducing the wrinkles. The air-drying assembly dries the end thereof through the air duct, effectively improving the air-drying efficiency and avoiding water residue.

[0018] 2. The present invention further improves the air-drying effect of deeper wrinkles by setting a clamping assembly, an air-drying assembly and an extrusion assembly. During use, the linear drive unit causes the clamping mounting frames on both sides to slide simultaneously towards the side close to the product. At this time, gas enters the three-way inlet pipe through the second air outlet end, and the blocking part is inflated. Subsequently, the switching rod is quickly reset to store the gas in the blocking part, and the blocking part remains in an inflated state. Then, the three-way valve is used to control the intermittent connection between the inlet pipe and the second air outlet end to achieve the reciprocating sliding of the traction plate, further squeezing the end of the product. While the traction plate slides, the clamping assembly pushes any explosives in the package towards its end, fully stretching the wrinkles at its end, facilitating the air-drying of the deeper wrinkled part of the package. At the same time, the air outlet area during air-drying is adjusted, thereby controlling the air velocity at the air outlet, increasing the air pressure at the air outlet, making the moisture in the wrinkles easier to be blown out, effectively reducing the moisture residue, and improving the product quality.

[0019] 3. The present invention effectively solves the problem of being unable to blow-dry the ends of products at multiple angles by setting a lower conveyor belt and an upper conveyor belt. During use, the clamping assembly is controlled to release the product, and the rotation difference between the upper conveyor belt and the lower conveyor belt is used to rotate the product by a certain angle. Subsequently, the clamping assembly is controlled to clamp the product again to blow-dry its end, avoiding the problem of more moisture residue caused by some wrinkles not being unfolded.

[0020] 4. The present invention effectively improves the air-drying efficiency by setting multiple groups of linear drive units, clamping mounting frames, clamping assemblies, air-drying assemblies, traction plates, extrusion assemblies and switching control units. During use, the ends of multiple products can be air-dried simultaneously, and different air-drying states can be set to avoid frequent adjustment of the working state. Moreover, the pause time of the upper conveyor belt and the lower conveyor belt can be reduced. For products with less moisture at the ends, some components such as the linear drive units can be turned off to achieve the purpose of energy conservation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The present invention provides as Figures 1 to 10The air-drying and conveying device for emulsion explosive production shown in the figure includes a lower conveyor belt 1, which is of a hollow structure and is used to convey products that need to be air-dried. Belt pulleys are sleeved at both ends of the lower conveyor belt 1 and are connected to a driving motor; a linear driving part 2, which is placed above the conveyor belt, and symmetrically fixed clamping mounting brackets 3 are connected to the output ends on both sides thereof. The linear driving part 2 can be a linear motor or a hydraulic rod and other components that can achieve linear driving. During use, it is connected to the corresponding controller. It should be noted that when the clamping mounting brackets 3 on the left and right sides are pushed by the linear driving part 2, they slide in opposite directions at the same time. Before use, the relative distance between the clamping mounting brackets 3 on both sides can be adjusted through the linear driving part 2 according to the product length to achieve the purpose of adapting to products of different lengths; a clamping assembly 4, which is installed on both sides of the clamping mounting bracket 3 and is used to clamp the product. During use, it is used to clamp any explosive after encapsulation and squeeze the end part, so as to reduce the wrinkles at the packaging end of the encapsulation and facilitate air-drying; an air-drying assembly 5, which is installed at the lower end of the clamping mounting bracket 3 and is used to blow-dry the product. The air-drying assembly 5 is placed on both sides of the extending direction of the lower conveyor belt 1. The air-drying assembly 5 includes an air cylinder 501, whose end is connected to the clamping mounting bracket 3. When blowing-drying the product, the product is pushed by the lower conveyor frame to move. When the product corresponds to the air cylinder 501, the product is clamped by the clamping assembly 4, and the air cylinder 501 is used to air-dry it.

[0034] It should be noted that sensors are installed at appropriate positions in the device to detect the position of the product and ensure that the clamping assembly 4 clamps the product in a timely manner so that the product corresponds to the air cylinder 501. The sensors are prior art and will not be described in detail here, nor are they shown in the figure.

[0035] It also includes a traction plate 6, which is slidably sleeved outside the air cylinder 501. The traction plate 6 can slide relative to the clamping mounting bracket 3. On the side of the traction plate 6 close to the conveyor belt, symmetrically arranged upper and lower extrusion assemblies 7 are slidably connected. The extrusion assemblies 7 and the clamping assembly 4 can better clamp the end part of the product and push and extrude the end part of the product when the traction plate 6 slides, so as to reduce the wrinkles at the packaging end of the product; a switching control part 8, which is used to adjust the position of the traction plate 6 and the air outlet area of the air cylinder 501.

[0036] Specifically, the air-drying component 5 further includes: a three-way valve 502, whose first air outlet end is communicated with the air inlet end of the air duct 501, and the second air outlet end is communicated with the air inlet end of the switching control unit 8. The three-way valve 502 is a solenoid valve, which is electrically connected to a corresponding controller and a power source during use. The electromagnetic three-way valve 502 is a prior art and will not be described in detail here. The three-way valve 502 is also provided with an air inlet pipe, and its end is communicated with an air pump; a hollow plate 503, which is fixedly installed at the air outlet end of the air duct 501 and is used to disperse the gas output by the air duct 501. A plurality of uniformly distributed air outlet holes are formed in the middle of the hollow plate 503. During use, the air flow penetrates the hollow plate 503 to air-dry the product; a blocking part 504, which is fixedly installed inside the air duct 501, and one side of which can be attached to the hollow plate 503 to block a part of the area of the hollow plate 503 and is used to adjust the air outlet area of the hollow plate 503. The blocking part 504 is communicated with the switching control unit 8. It should be noted that the side of the blocking part 504 close to the hollow plate 503 is made of rubber. When the blocking part 504 is inflated, it will expand and thus block some of the air outlet holes of the hollow plate 503.

[0037] It should be noted that the lower conveyor belt 1 pushes the product to the end of the air duct 501. The three-way valve 502 connects the air inlet pipe with the first air outlet end to air-dry the product. At this time, the air-drying state is the first state; the clamping component 4 clamps the product and aligns it with the air duct 501. At the same time, the clamping component 4 presses the end of the product to reduce the wrinkles at the end of the product. The air-drying component 5 dries the end of the product through the air duct 501. At this time, the air-drying state is the second state; the three-way valve 502 connects the air inlet pipe with the first air outlet end and the second air outlet end. The switching control unit 8 makes the blocking part 504 block some of the air outlet holes of the hollow plate 503 to reduce the air outlet area of the air duct 501, concentrate the air outlet position, enable the middle of the air duct 501 to continue to blow air, and can increase the air outlet pressure. Subsequently, the switching control unit 8 makes the three-way air inlet pipe 802 communicate with the second air outlet pipe 806, and controls the air inlet pipe of the three-way valve 502 to be intermittently connected with the second air outlet end while being connected with the first air outlet end, so that the second air outlet end and the air inlet pipe are repeatedly connected / disconnected. The squeezing component 7 pulls the clamping component 4 to slide left and right to further squeeze the end of the product, facilitating the air-drying of the wrinkled part of the package. At this time, the air-drying state is the third state.

[0038] More specifically, the switching control unit 8 includes: a switching sleeve 801 fixedly connected to the inner side of the air duct 501, and a three-way intake pipe 802 is connected to one side thereof. The three-way intake pipe 802 is connected to the second air outlet end of the three-way valve 502, and both ends and the middle of the three-way intake pipe 802 are connected to the switching sleeve 801; a switching rod 803 symmetrically arranged inside the switching sleeve 801 and hermetically slidably connected to the switching sleeve 801. The end of each switching rod 803 penetrates through the side wall of the air duct 501, and the switching rods 803 on the left and right sides slide in opposite directions at the same time; a first air outlet pipe 804 connected to the outside of the switching sleeve 801, and the other end thereof is connected to the blocking part 504. There are two first air outlet pipes 804 and they are symmetrically arranged on the left and right; a switching inclined platform 805 fixedly connected to the inner side of the corresponding pressing assembly 7, and each switching rod 803 is slidably connected to the corresponding switching inclined platform 805. During use, the position of the switching inclined platform 805 is adjusted by the movement of the corresponding pressing assembly 7, and at the same time, the switching inclined platform 805 pushes / pulls the switching rod 803 to move inside the switching sleeve 801.

[0039] It should be noted that when the intake pipe of the three-way valve 502 is connected to the second air outlet end, the position of the switching rod 803 is adjusted by the pressing assembly 7 to connect the three-way intake pipe 802 with the first air outlet pipe 804. As Figure 9 shown in state b in the figure, the gas enters the three-way intake pipe 802 through the second air outlet end, and the blocking part 504 is inflated. The blocking part 504 deforms to block a part of the area of the hollow plate 503, reducing the air outlet area of the air duct 501. Subsequently, the switching rod 803 is quickly reset to store the gas in the blocking part 504 and keep the blocking part 504 in an inflated state.

[0040] Specifically, the switching control unit 8 further includes: a second air outlet pipe 806 connected to the outside of the switching sleeve 801 and penetrating through the side wall of the air duct 501. The second air outlet pipe 806 is in a Y shape, and both ends are symmetrically connected to the outside of the switching sleeve 801; a pneumatic extension part 807 connected to the second air outlet pipe 806, and both ends are respectively fixedly connected to the clamping mounting bracket 3 and the traction plate 6, and is used to push the traction plate 6 to slide relative to the clamping mounting bracket 3. The pneumatic extension part 807 can adopt components such as a self-resetting cylinder that extends in length when pressurized and automatically resets when not pressurized. The specific components are not limited here.

[0041] It should be noted that when the intake pipe of the three-way valve 502 is connected to the second air outlet end, the three-way intake pipe 802 is connected to the second air outlet pipe 806 by adjusting the pressing assembly 7. As Figure 9In state a, the gas enters the tee inlet pipe 802 through the second outlet end and enters the pneumatic extension part 807. The pneumatic extension part 807 extends under the air pressure, enabling the traction plate 6 to slide relative to the clamping mounting bracket 3 and adjust the position of the traction plate 6. When the tee inlet pipe 802 is disconnected from the second outlet pipe 806, the pneumatic extension part 807 resets, causing the traction plate 6 to reset synchronously. By controlling the intermittent connection between the inlet pipe and the second outlet end through the three-way valve 502, the reciprocating sliding of the traction plate 6 is achieved.

[0042] It should be noted that when the inlet pipe of the three-way valve 502 is not connected to the second outlet end, the switching rod 803 moves to connect the first outlet pipe 804 to the second outlet pipe 806. As Figure 10 shown in the state, at this time, the gas in the blocking part 504 enters the second outlet pipe 806 through the first outlet pipe 804 and is discharged through the pneumatic extension part 807, causing the blocking part 504 to reset. It should be noted that the gas volume in the blocking part 504 is limited, and it cannot provide a stable air pressure supply for the pneumatic extension part 807 when it is connected to the second outlet pipe 806, so that the gas can be discharged through the pneumatic extension part 807.

[0043] Specifically, the clamping assembly 4 includes: clamping rods 401, which are symmetrically arranged on the upper and lower sides of the end of the product for clamping the product. When the clamping rods 401 clamp the product, the lower conveyor belt 1 stops conveying to avoid friction between the lower conveyor belt 1 and the product packaging, causing wear on the outer packaging of the product; drive rods 402, which are symmetrically arranged at both ends of the clamping rods 401, and a guiding chute 403 is provided in the middle. The end of the clamping rod 401 is placed in the guiding chute 403 and can slide along the guiding chute 403. When the squeezing assembly 7 slides, it pulls the clamping rod 401 to slide along the guiding chute 403, changing the clamping position of the clamping rod 401 relative to the product, and further reducing the wrinkles at the end of the product packaging; a reset reed 404, which is placed in the guiding chute 403, with one end fixedly connected to the end of the clamping rod 401 and the other end fixedly connected to the drive rod 402. When the squeezing assembly 7 no longer pulls the clamping rod 401 to move, the reset reed 404 pushes the clamping rod 401 to slide along the guiding chute 403 and reset; electromagnetic mounting brackets 405, which are symmetrically arranged on both sides of the clamping mounting bracket 3 and are installed on both sides of the clamping mounting bracket 3 by bolts. They can be installed at appropriate positions on the clamping mounting bracket 3 according to requirements during use. A suction part 406 is fixedly connected to the lower end of the electromagnetic mounting bracket 405. The suction part 406 can adopt components such as a battery coil or a cylinder that can generate linear motion and is connected to the corresponding controller during use. The specific components are not limited here.

[0044] It should be noted that two driving rods 402 that are symmetric up and down are placed in the same attracting part 406 and are driven by the attracting part 406 to move in opposite directions at the same time. When in use, the corresponding two driving rods 402 are synchronously slid in the approaching direction through the attracting part 406. At this time, the driving rods 402 clamp the product through the clamping rods 401; similarly, when the two driving rods 402 are simultaneously slid in the separating direction through the attracting part 406, the clamping rods 401 release the product, enabling the product to move along with the lower conveyor belt 1; the initial positions of the upper and lower clamping rods 401 can be adjusted through the attracting part 406 to achieve the purpose of being applicable to products of different diameters.

[0045] More specifically, the air-drying assembly 5 further includes: a guiding rod 505, which is fixedly connected to one side of the traction plate 6. Each pressing assembly 7 passes through the corresponding guiding rod 505 and is slidably matched with the guiding rod 505. The guiding rod 505 is installed on one side of the traction plate 6 through the corresponding angle code and bolts.

[0046] Specifically, the pressing assembly 7 includes: a U-shaped frame 701, which is slidably sleeved outside the guiding rod 505, and adjusting bolts 702 are threadedly installed at both ends. The middle part of the U-shaped frame 701 is in sliding contact with the traction plate 6; a U-shaped inclined plate 703, which is rotatably connected to the end of the U-shaped frame 701, and the inclined surface is in contact with the clamping rod 401. The end of the inclined surface is hook-shaped, which is convenient for the U-shaped inclined plate 703 to pull the clamping rod 401 to move. An inclined platform 704 is fixedly connected to the U-shaped inclined plate 703 corresponding to the position of the adjusting bolt 702. The end of the adjusting bolt 702 is in contact with the inclined platform 704, which is used to adjust the maximum angle of rotation of the U-shaped inclined plate 703 relative to the U-shaped frame 701. When the clamping rod 401 clamps the product, the inclined surface of the U-shaped inclined plate 703 is in contact with the clamping rod 401. At this time, it is the maximum angle of the U-shaped inclined surface relative to the U-shaped frame 701. Just adjust the end of the adjusting bolt 702 to be in contact with the inclined surface; an elastic reed 705, whose two ends are respectively fixedly connected to the ends of the U-shaped frame 701 and the U-shaped inclined plate 703. The elastic reed 705 is used to make the U-shaped inclined plate 703 contact with the clamping rod 401.

[0047] It should be noted that the position of the adjusting bolt 702 is manually adjusted according to the diameter of the product to control the maximum flipping angle of the U-shaped inclined plate 703 relative to the U-shaped frame 701. During the working process, the clamping mounting frames 3 on the left and right sides are simultaneously slid towards the side close to the product through the linear driving part 2. At this time, the clamping rod 401 presses the U-shaped inclined plate 703, causing the pressing assembly 7 to slide towards the side away from the air duct 501. During this process, the switching platform 805 is switched to move the switching rod 803, injecting air into the blocking part 504. After the blocking part 504 blocks some air outlets of the hollowed-out plate 503, the clamping mounting frame 3 is quickly reset through the linear driving part 2 to keep the gas in the blocking part 504.

[0048] It should be noted that when the air inlet pipe of the three-way valve 502 is not connected to the second air outlet end, the linear driving part 2 is used to push the clamping mounting brackets 3 on both sides to slide towards the side close to the product, so that the end of the air duct 501 close to the product is lifted to improve the air drying effect. At this time, the air drying state is the fourth state.

[0049] More specifically, it further includes: an upper conveyor belt 9, which is placed above the lower conveyor belt 1 and is provided with a plurality of them at intervals. Both ends of the upper conveyor belt 9 are sleeved with pulleys, and a plurality of them rotate synchronously. One side of the pulley is connected with a motor for driving the upper conveyor belt 9 to move; the product is placed between the upper conveyor belt 9 and the lower conveyor belt 1 and is perpendicular to the extending direction of the upper conveyor belt 9 / the lower conveyor belt 1; the upper conveyor belt 9 can adjust its upper and lower positions relative to the lower conveyor belt 1 to be applicable to products with different diameters. The specific adjustment method is not limited here, and the specific structure is not shown in the figure either.

[0050] It should be noted that the driving motors of the upper conveyor belt 9 and the lower conveyor belt 1 are both prior arts and will not be described in detail here. As shown in the figure, they are respectively connected to the corresponding controllers and power supplies during use. During the use process, the rotation speeds of the upper conveyor belt 9 and the lower conveyor belt 1 can be made different through the controller, so that the product can rotate relative to the lower conveyor belt 1 / the upper conveyor belt 9 while the product is being conveyed, improving the air drying effect.

[0051] Specifically, it further includes: a rectangular blower 10, which is placed above the upper conveyor belt 9 and is used to dry the product. When in use, the rectangular blower 10 is electrically connected to the corresponding controller and power supply. When in use, the middle part of the product is dried by the rectangular motor, and the circumference of the product is air-dried in cooperation with the rotation of the product; a blanking plate 11, which is placed at the end of the lower conveyor belt 1 and is used to receive the air-dried product to prevent the product from falling and being knocked.

[0052] It should be noted that a plurality of linear driving parts 2 are arranged along the extending direction of the lower conveyor belt 1, and the same clamping components 4 and other supporting components are synchronously increased to achieve the purpose of simultaneously clamping and air-drying the ends of multiple products. At the same time, the remaining components below the plurality of linear driving parts 2 can be partially set to the first state / the fourth state to avoid frequent adjustment of the working state, and can reduce the pause time of the upper conveyor belt 9 and the lower conveyor belt 1, improving the air drying efficiency.

[0053] In summary, when in use, place the product to be air-dried at the upper end of the lower conveyor belt 1, and convey the product to the lower part of the rectangular fan 10 through the upper conveyor belt 9. During this process, the rectangular fan 10 air-dries the product circumferentially, and at the same time, the air duct 501 blows air towards the end of the product to air-dry the end of the product; when it is necessary to air-dry the inside of the end fold of the product, the conveyor belt pushes the product to move. When the product moves to the position corresponding to the air duct 501, the clamping rod 401 is driven by the attracting part 406 to clamp the product, and the rotation of the upper conveyor belt 9 and the lower conveyor belt 1 is stopped. At this time, the clamping assembly 4 presses the end of the product to reduce the end fold of the product, and the air-drying assembly 5 dries the end of the product through the air duct 501.

[0054] For products with a larger diameter, the end folds are deeper and more numerous, and it is necessary to further air-dry the folded positions. Connect its air inlet pipe to the second air outlet end through the three-way valve 502, and make the clamping mounting brackets 3 on both sides slide towards the side close to the product simultaneously through the linear driving part 2. At this time, the clamping rod 401 presses the U-shaped inclined plate 703, so that the pressing assembly 7 slides away from the air duct 501, making the three-way air inlet pipe 802 communicate with the first air outlet pipe 804. The gas enters the three-way air inlet pipe 802 through the second air outlet end, and makes the blocking part 504 inflate and expand, reducing the air outlet area of the air duct 501. Then quickly reset the switching rod 803 to store the gas in the blocking part 504 and keep the blocking part 504 in an expanded state. Control the intermittent connection of the air inlet pipe and the second air outlet end through the three-way valve 502 to realize the reciprocating sliding of the traction plate 6, further squeezing the end of the product to facilitate air-drying the folded part of the package. After circulating for a certain time, control the clamping assembly 4 to release the product, and make the product rotate a certain angle through the rotation difference between the upper conveyor belt 9 and the lower conveyor belt 1. Then control the clamping assembly 4 to clamp the product again, squeeze and air-dry its end, avoiding the problem of poor air-drying effect caused by some folds not being unfolded.

[0055] For products with little moisture or shallow folds at the ends, the air inlet pipe of the three-way valve 502 can be disconnected from the second air outlet end, and the clamping mounting brackets 3 on both sides are pushed towards the side close to the product through the linear driving part 2 to make the air duct 501 close to the end of the product and improve the air-drying effect.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
