Description

Technical Field

[0001] The invention relates to the technical field of air-drying and conveying emulsion explosives, in particular to a blow-drying and conveying device for producing emulsion explosives. Background Art

[0002] As a highly safe industrial explosive, emulsion explosives undergo multiple steps in their production, including mixing, filling, and packaging. During the production process, the rolls need to be transported to a water pool for cooling and then blown dry by a drying device. However, wrinkles are prone to form 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, which increases the depth of the wrinkles.

[0003] For example, the drug coil cooling and conveying system for emulsion explosives production, disclosed in application number CN202122214305.0, includes a base with a water tank affixed to its top. A longitudinal conveyor belt is positioned within the water tank, and first mesh panels are evenly affixed to the outer sides of the longitudinal conveyor belt. A cooling chamber is defined at the bottom of the water tank. The longitudinal conveyor belt within the water tank, through the inclined first mesh panels on the longitudinal conveyor belt, enables the drug coil to be conveyed downward and retrieved during transport.

[0004] For example, the application number CN202410848345.6 discloses a conveying device with a blow-drying function for the production of emulsion explosives. The device comprises a platform, a rotating structure, an axial rotating arm, a controller, and an automatic clamping structure for clamping a container containing emulsion explosives. The device also comprises a blow-drying structure, wherein the blow-drying structure comprises at least one electric blower, the electric blower comprising a base and an electric blower body fixed to the base, the base being arranged on the vertical end of an inclined member located on the lower surface of a circular disk, the blower mouth of the electric blower body being arranged toward the longitudinal center axis of the circular disk; or the electric blower is arranged on the lower surface of the circular disk; the control end of the electric blower body is electrically connected to the controller after being wound around the automatic clamping structure via an electric blower transmission line. By providing a blow-drying structure for air-drying the emulsion explosive in the clamped container, the device has a blow-drying function.

[0005] The above technical solution has some problems during use. It is difficult to air-dry the wrinkled parts, resulting in poor air-drying effect. It is also inconvenient to adjust according to the size of the explosives, and the wind speed during air-drying cannot be dynamically adjusted.

[0006] Therefore, it is necessary to invent and adopt emulsion explosive production to solve the above problems with a blow-drying conveying device. Summary of the Invention

[0017] The technical effects and advantages of the present invention are as follows:

[0018] 1. The present invention effectively achieves the purpose of air-drying the wrinkle position by setting a clamping component and an air-drying component. When in use, the product is clamped by the clamping rod, and the upper conveyor belt and the lower conveyor belt are stopped from rotating. At this time, the clamping component presses the end of the product to stretch the wrinkles at the end of the product and reduce wrinkles. The air-drying component blows the end dry through the air duct, effectively improving the air-drying efficiency and avoiding moisture residue.

[0019] 2. The present invention further improves the air-drying effect of deeper folds by arranging a clamping component, an air-drying component and an extrusion component. When in use, the linear driving part is used to make the clamping mounting frames on the left and right sides slide toward the side close to the product at the same time. At this time, the gas enters the three-way air inlet pipe through the second air outlet end and inflates the sealing part. Then the switching rod is quickly reset to keep the gas in the sealing part, and the sealing part remains in an expanded state. Then the air inlet pipe is controlled to be intermittently connected to the second air outlet end through the three-way valve to realize the reciprocating sliding of the traction plate, further squeezing the end of the product. While the traction plate slides, the clamping component pushes the explosives in the package to move toward its end, so that the folds at its end are fully expanded, which is convenient for air-drying the deeper folds of the package, and at the same time achieves the adjustment of the air outlet area during blow-drying, thereby controlling the wind speed of the air outlet, increasing the pressure of the air outlet, making it easier to blow out the moisture in the folds, effectively reducing moisture residue and improving product quality.

[0020] 3. The present invention effectively solves the problem of being unable to dry the ends of the product at multiple angles by setting up a lower conveyor belt and an upper conveyor belt. When in use, the clamping component is controlled to release the product, and the product is rotated to a certain angle through the rotation difference between the upper conveyor belt and the lower conveyor belt. Then, the clamping component is controlled to clamp the product again to air-dry its ends, avoiding the problem of more moisture remaining due to some wrinkles not unfolding.

[0021] 4. The present invention effectively improves the air-drying efficiency by setting multiple groups of linear drive parts, clamping mounting frames, clamping components, air-drying components, traction plates, extrusion components and switching control parts. When in use, the ends of multiple products can be air-dried at the same time, and different air-drying states can be set to avoid frequent adjustment of the working state, and the pause time of the upper conveyor belt and the lower conveyor belt can be reduced. For products with little moisture at the ends, some linear drive parts and other components can be turned off to achieve the purpose of energy saving. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The present invention provides Figures 1 to 10The blow-drying conveying device for the production of emulsion explosives shown includes a lower conveyor belt 1, which is a hollow structure and is used to convey products that need to be air-dried. Pulleys are provided at both ends of the lower conveyor belt 1 and are connected to a drive motor; a linear drive part 2 is placed above the conveyor belt, and its output ends on both sides are symmetrically fixedly connected to clamping mounting frames 3. The linear drive part 2 can be a linear motor or a hydraulic rod or other component that can achieve linear drive, and is connected to the corresponding controller when in use. It should be noted that the clamping mounting frames 3 on the left and right sides slide in opposite directions at the same time when pushed by the linear drive part 2. Before use, the clamping mounting frames 3 on both sides can be adjusted according to the length of the product through the linear drive part 2. The relative spacing is achieved to achieve the purpose of being suitable for products of different lengths; the clamping component 4, which is installed on both sides of the clamping mounting frame 3, is used to clamp the product. When in use, it is used to clamp the packaged explosives and squeeze the end to reduce the wrinkles on the end of the packaged package, which is convenient for air drying; the air drying component 5, which is installed at the lower end of the clamping mounting frame 3, is used to blow dry the product. The air drying component 5 is placed on both sides of the extension direction of the lower conveyor belt 1. The air drying component 5 includes an air cylinder 501, whose end is connected to the clamping mounting frame 3. When the product is blown dry, the lower conveyor frame pushes the product to move. When the product corresponds to the air cylinder 501, the clamping component 4 clamps the product, and the air cylinder 501 blows it dry.

[0035] It should be noted that a sensor is installed at an appropriate position in the device to detect the position of the product and ensure that the clamping component 4 clamps the product at the right time so that the product corresponds to the wind tube 501. The sensor is a prior art and will not be described in detail here and is not shown in the figure.

[0036] It also includes a traction plate 6, which is slidably mounted on the outside of the air duct 501. The traction plate 6 can slide relative to the clamping mounting frame 3. The traction plate 6 is slidably connected to the side of the conveyor belt with an extrusion component 7 that is symmetrically arranged up and down. The extrusion component 7 is combined with the clamping component 4 to better clamp the end of the product and push the end of the extruded product when the traction plate 6 slides, thereby reducing wrinkles at the end of the product packaging; a switching control unit 8 is used to adjust the position of the traction plate 6 and the air outlet area of ​​the air duct 501.

[0037] Specifically, the air-drying component 5 also includes: a three-way valve 502, a first air outlet end of which is connected to the air inlet end of the air duct 501, and a second air outlet end of which is connected to the air inlet end of the switching control unit 8. The three-way valve 502 is an electromagnetic valve, which is electrically connected to the corresponding controller and power supply when in 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, an end of which is connected to the 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. The middle of the hollow plate 503 There are multiple evenly distributed air outlets at the beginning. When in use, the air flow penetrates the hollow plate 503 to dry the product; the sealing part 504 is fixedly installed on the inner side of the air duct 501, and one side can fit with the hollow plate 503 to block part of the area of ​​the hollow plate 503, and is used to adjust the air outlet area of ​​the hollow plate 503. The sealing part 504 is connected to the switching control part 8. It should be noted that the side of the sealing part 504 close to the hollow plate 503 is made of rubber. When the sealing part 504 is inflated, it will expand, thereby blocking part of the air outlet holes of the hollow plate 503.

[0038] It should be noted that the lower conveyor belt 1 pushes the product to the end of the air duct 501, and 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 makes it correspond to 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 blows its end dry 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, and the switching control unit 8 makes the blocking part 504 block the hollow plate 5 Some of the air outlet holes in 03 reduce the air outlet area of ​​the air duct 501 and concentrate the air outlet position, so that the middle part of the air duct 501 continues to discharge air and the air outlet pressure can be increased. Then, the control unit 8 is switched to connect the three-way air inlet pipe 802 with the second air outlet pipe 806, and the connection between the air inlet pipe of the three-way valve 502 and the first air outlet end is controlled while the second air outlet end is intermittently connected with the air inlet pipe, so that the second air outlet end and the air inlet pipe are repeatedly connected / disconnected, and the extrusion component 7 pulls the clamping component 4 to slide left and right, further squeezing the end of the product to facilitate air-drying the wrinkled part of the packaging. At this time, the air-drying state is the third state.

[0039] More specifically, the switching control unit 8 includes: a switching sleeve 801, which is fixedly connected to the inner side of the air duct 501 and is connected to a three-way air inlet pipe 802 on one side. The three-way air inlet pipe 802 is connected to the second air outlet end of the three-way valve 502, and the two ends and the middle of the three-way air inlet pipe 802 are connected to the switching sleeve 801; a switching rod 803, which is symmetrically arranged on the inner side of the switching sleeve 801 and is sealed and slidably connected to the switching sleeve 801. The end of each switching rod 803 passes through the side wall of the air duct 501, and the switching rods 803 on the left and right sides are simultaneously Slide in the opposite direction; the first air outlet pipe 804, which is connected to the outside of the switching sleeve 801, and the other end is connected to the blocking part 504, and the first air outlet pipe 804 is provided with two and is symmetrically arranged on the left and right; the switching ramp 805 is fixedly connected to the inner side of the corresponding extrusion component 7, and each switching rod 803 is slidingly connected to the corresponding switching ramp 805. When in use, the position of the switching ramp 805 is adjusted by moving the corresponding extrusion component 7, and at the same time, the switching ramp 805 pushes / pull the switching rod 803 to move in the switching sleeve 801.

[0040] It should be noted that when the air inlet pipe of the three-way valve 502 is connected to the second air outlet, the position of the switching rod 803 is adjusted by the extrusion component 7 to connect the three-way air inlet pipe 802 to the first air outlet pipe 804. Figure 9 In the middle b state, the gas enters the three-way air inlet pipe 802 through the second air outlet end, and inflates the sealing part 504. The sealing part 504 deforms to block part of the hollow plate 503 area, reducing the air outlet area of ​​the air duct 501. Then the switching rod 803 is quickly reset to keep the gas in the sealing part 504 and keep the sealing part 504 in an expanded state.

[0041] Specifically, the switching control unit 8 also includes: a second air outlet pipe 806, which is connected to the outside of the switching sleeve 801 and passes through the side wall of the air duct 501. The second air outlet pipe 806 is Y-shaped, and both ends are symmetrically connected to the outside of the switching sleeve 801; a pneumatic extension part 807, which is connected to the second air outlet pipe 806, and its two ends are respectively fixedly connected to the clamping mounting frame 3 and the traction plate 6, and is used to push the traction plate 6 to slide relative to the clamping mounting frame 3. The pneumatic extension part 807 can adopt a self-resetting cylinder or the like to extend the length when pressurized and automatically reset when not pressurized. The specific components are not limited here.

[0042] It should be noted that when the air inlet pipe of the three-way valve 502 is connected to the second air outlet end, the three-way air inlet pipe 802 is adjusted to be connected to the second air outlet pipe 806 by the extrusion component 7, as shown in FIG. Figure 9In state a, the gas enters the three-way air inlet pipe 802 through the second air outlet end and enters the pneumatic extension part 807. The pneumatic extension part 807 is extended by the air pressure, so that the traction plate 6 can slide relative to the clamping mounting frame 3, and the position of the traction plate 6 is adjusted. When the three-way air inlet pipe 802 is disconnected from the second air outlet pipe 806, the pneumatic extension part 807 is reset, so that the traction plate 6 is reset synchronously, and the air inlet pipe is controlled to be intermittently connected to the second air outlet end through the three-way valve 502, so that the traction plate 6 can slide back and forth.

[0043] It should be noted that when the air inlet pipe of the three-way valve 502 is not connected to the second air outlet, the switch rod 803 moves to connect the first air outlet pipe 804 with the second air outlet pipe 806. Figure 10 In the state shown, the gas in the sealing part 504 enters the second air outlet pipe 806 through the first air outlet pipe 804 and is discharged through the pneumatic extension part 807, so that the sealing part 504 is reset. It should be noted that the gas capacity in the sealing part 504 is limited. When it is connected to the second air outlet pipe 806, it cannot provide a stable air pressure supply to the pneumatic extension part 807, so that the gas can be discharged through the pneumatic extension part 807.

[0044] Specifically, the clamping assembly 4 includes: a clamping rod 401, which is symmetrically arranged at the upper and lower sides of the end of the product and is used to clamp the product. When the clamping rod 401 clamps the product, the lower conveyor belt 1 stops conveying to avoid friction between the lower conveyor belt 1 and the product packaging, which causes wear of the product outer packaging; a driving rod 402, which is symmetrically arranged at both ends of the clamping rod 401, and a guide groove 403 is opened in the middle. The end of the clamping rod 401 is placed in the guide groove 403 and can slide along the guide groove 403. When the extrusion assembly 7 slides, it pulls the clamping rod 401 to slide along the guide groove 403, changing the clamping position of the clamping rod 401 relative to the product, further reducing the wrinkles at the end of the product packaging; a reset spring 404, which is placed in the guide groove The guide rail 402 is fixed to the guide rail 404 and the guide rail 403 is fixed to the guide rail 404. ...

[0045] It should be pointed out that the two symmetrical driving rods 402 are placed in the same suction part 406, and are driven by the suction 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 direction of approach through the suction part 406. At this time, the driving rod 402 clamps the product through the clamping rod 401; similarly, when the two driving rods 402 are simultaneously slid in the direction of separation through the suction part 406, the clamping rod 401 releases the product, so that the product can move with the lower conveyor belt 1; the initial positions of the upper and lower clamping rods 401 can be adjusted through the suction part 406 to achieve the purpose of being suitable for products of different diameters.

[0046] More specifically, the air-drying component 5 also includes: a guide rod 505, which is fixedly connected to one side of the traction plate 6, each extrusion component 7 passes through the corresponding guide rod 505, and slides with the guide rod 505, and the guide rod 505 is installed on one side of the traction plate 6 through corresponding angle codes and bolts.

[0047] Specifically, the extrusion assembly 7 includes: a U-shaped frame 701, which is slidably mounted on the outside of the guide rod 505, with adjusting bolts 702 threadedly installed at both ends, and 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, and 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, and the U-shaped inclined plate 703 is fixedly connected to the position of the adjusting bolt 702 with a tilting platform 704, and the end of the adjusting bolt 702 is fixedly connected to the U-shaped inclined plate 703. The end of the adjusting bolt 702 contacts the inclined surface; the elastic spring 705 has its two ends fixedly connected to the U-shaped frame 701 and the end of the U-shaped inclined plate 703 respectively. The elastic spring 705 is used to make the U-shaped inclined plate 703 contact with the clamping rod 401.

[0048] 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 operation, the linear drive unit 2 is used to make the clamping mounting frames 3 on both sides slide toward the side close to the product at the same time. At this time, the clamping rod 401 squeezes the U-shaped inclined plate 703 to make the extrusion assembly 7 slide toward the side away from the air duct 501. During this process, the inclined platform 805 is switched to move the switching rod 803 to inject air into the blocking part 504. After the blocking part 504 blocks part of the air outlet of the hollow plate 503, the linear drive unit 2 is used to quickly reset the clamping mounting frame 3 to keep the gas in the blocking part 504.

[0049] It should be pointed out that when the air inlet pipe of the three-way valve 502 is not connected to the second air outlet end, the linear drive unit 2 pushes the clamping mounting frames 3 on both sides to slide toward the side close to the product, so that the air duct 501 is close to the end of the product, thereby improving the air-drying effect. At this time, the air-drying state is the fourth state.

[0050] More specifically, it also includes: an upper conveyor belt 9, which is placed above the lower conveyor belt 1, and is arranged in multiple numbers at intervals. Both ends of the upper conveyor belt 9 are equipped with pulleys, and the multiple pulleys rotate synchronously. One side of the pulley is connected to 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 extension direction of the upper conveyor belt 9 / lower conveyor belt 1; the upper conveyor belt 9 can adjust the upper and lower positions relative to the lower conveyor belt 1 to be suitable for products of different diameters. The specific adjustment method is not limited here, and the specific structure is not shown in the figure.

[0051] It should be pointed out that the driving motor of the upper conveyor belt 9 and the motor of the lower conveyor belt 1 are both existing technologies and will not be described in detail here. As shown in the figure, they are respectively connected to the corresponding controller and power supply when in use. During use, the controller can be used to make the upper conveyor belt 9 and the lower conveyor belt 1 rotate at different speeds, so that the product can rotate relative to the lower conveyor belt 1 / upper conveyor belt 9 while conveying the product, thereby improving the air-drying effect.

[0052] Specifically, it also includes: a rectangular fan 10, which is placed above the upper conveyor belt 9 and is used to blow dry the product. When in use, the rectangular fan 10 is electrically connected to the corresponding controller and power supply. When in use, the middle part of the product is blown dry by the rectangular motor, and the circumference of the product is dried in conjunction 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 dried product to prevent the product from falling and causing bumps.

[0053] It should be pointed out that there are multiple linear drive parts 2 along the extension direction of the lower conveyor belt 1, and other supporting components such as the same clamping component 4 are added simultaneously to achieve the purpose of clamping and drying the ends of multiple products at the same time. At the same time, the remaining components under the multiple linear drive parts 2 can be partially set to the first state / 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, thereby improving the drying efficiency.

[0054] In summary, when in use, the product to be air-dried is placed on the upper end of the lower conveyor belt 1, and the product is conveyed to the bottom of the rectangular fan 10 through the upper conveyor belt 9. During this process, the rectangular fan 10 air-dries the product in the circumference, and at the same time, the air duct 501 blows air to the end of the product to air-dry the end of the product; when the wrinkles at the end of the product need to be air-dried, 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 suction part 406 to clamp the product, and the upper conveyor belt 9 and the lower conveyor belt 1 are stopped from rotating. At this time, the clamping component 4 presses the end of the product to reduce the wrinkles at the end of the product, and the air-drying component 5 blows its end dry through the air duct 501.

[0055] For products with larger diameters, the wrinkles at the end are deeper and more numerous, and further air drying is required for the wrinkle positions. The air inlet pipe is connected to the second air outlet through the three-way valve 502, and the clamping mounting frames 3 on the left and right sides are simultaneously slid toward the side close to the product through the linear drive unit 2. At this time, the clamping rod 401 squeezes the U-shaped inclined plate 703, causing the extrusion assembly 7 to slide toward the side away from the air duct 501, so that the three-way air inlet pipe 802 is connected to the first air outlet pipe 804, and the gas enters the three-way air inlet pipe 802 through the second air outlet, and inflates the blocking part 504, reducing the air outlet area of ​​the air duct 501. , and then quickly reset the switching rod 803 to keep the gas in the sealing part 504, so that the sealing part 504 remains in an expanded state, and the air inlet pipe is controlled to be intermittently connected to the second air outlet end through the three-way valve 502, so that the traction plate 6 can slide back and forth, further squeezing the end of the product to facilitate air-drying the wrinkled part of the package. After a certain period of circulation, the clamping component 4 is controlled to release the product, and the product is rotated to a certain angle through the rotation difference between the upper conveyor belt 9 and the lower conveyor belt 1. Then, the clamping component 4 is controlled to clamp the product again, squeeze and air-dry its end, and avoid the problem of poor air-drying effect caused by some wrinkles not unfolding.

[0056] For products with little moisture at the end or shallow wrinkles, the air inlet pipe of the three-way valve 502 can be disconnected from the second air outlet end, and the clamping mounting frames 3 on both sides can be pushed to slide toward the side close to the product through the linear drive unit 2, so that the air duct 501 is close to the end of the product, thereby improving the drying effect.
