Description

Technical Field

[0001] This invention relates to the field of detonator drying technology, and in particular to a fully automatic intelligent detonator drying line. Background Technology

[0002] Detonators are commonly used initiating materials in blasting engineering. They are mainly used to initiate the detonation of various explosives, detonating cords, and detonating tubes. They are mainly divided into electronic-based detonators and non-electronic-based detonators. Drying is a necessary process in the production of electronic-based detonators. Traditional drying methods generally use natural drying, which is inefficient and costly. Existing technology discloses a crescent-shaped plate conveyor dryer (publication number CN2884086Y), which mainly uses a combined infrared and hot air heating drying method. The crescent-shaped plate conveyor trolley is entirely installed inside the dryer housing. During drying, the discharge door is closed to reduce heat loss, resulting in high heating efficiency and fast drying. The crescent-shaped plate conveyor... The trolley runs on a circular track, reducing the floor space required. However, the technology disclosed in this patent document still has many problems: ① Poor safety: Electric detonators pose an explosion risk when subjected to strong collisions or scrapes. Therefore, it is necessary to ensure stable operation during the drying process and avoid tilting, bumping, or scraping. The equipment disclosed in the aforementioned patent document does not have a structural design for safety. ② Large space occupation: Because the entire drying operation of electric detonators is quite dangerous, the drying equipment needs to be placed in a closed space and far away from human activity areas. The equipment disclosed in the aforementioned patent document requires a circular track, which occupies a large space, resulting in a large overall space occupation for the drying equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a fully automatic intelligent detonator drying line to solve the technical problems of low safety and large space occupation in existing detonator drying lines.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A fully automatic intelligent detonator drying line includes a top rail, a loading section, a ground rail, a forklift section, at least one drying chamber, an automatic temperature control system for automatically maintaining a constant temperature within the drying chamber, and a unloading section. The loading section receives several drying pallets transported to a designated position by the top rail and sequentially pushes the drying pallets onto a drying rack. The forklift section, mounted on the ground rail, is used to convey the drying rack into the drying chamber for drying and to remove the drying rack and convey it to the unloading section. The unloading section sequentially unloads the drying pallets from the drying rack. The material is pushed onto the conveyor belt. The fork is a bidirectional telescopic fork, located between the drying chamber and the unloading and loading sections. The drying chamber has a door that opens vertically. Slider blocks are installed at both ends of the door. The sliders slide in grooves within guide blocks on the outer walls of the chamber. A locking cylinder is installed on the outer wall of the chamber, with its power end installed on the door. A pneumatic pin is also installed on the outer wall of the chamber, used to limit the door when it is closed or open.

[0006] Furthermore, a water channel is provided in the sealed cavity between the outer wall and the inner wall of the drying oven. The water channel consists of several parallel water pipes connected in series. The inner cavity of the water pipes is in direct contact with the inner wall of the oven and is welded to the inner wall. The cavity between the water channel and the outer wall of the oven is filled with thermal insulation material.

[0007] Furthermore, the inlet and outlet of the water circuit are connected to an external hot water supply station, a vacuum pump is connected inside the drying chamber, and the door of the drying chamber is interlocked with the forklift.

[0008] Furthermore, the drying rack is configured as a double-layer structure with several channels in each layer. Each channel is used to store multiple drying trays. Several ventilation holes are provided on the side wall of the drying rack. A positioning block is provided at the bottom of the drying rack. The positioning block cooperates with the positioning pins on the upper surface of the loading platform and the unloading platform to position and limit the drying rack. Both the loading platform and the unloading platform are equipped with inspection sensors.

[0009] Furthermore, mechanical baffles are installed at the inlet and outlet ports on both sides of the drying rack. The baffles are slidably inserted into the shaft holes at the ends of the drying rack via guide shafts. When the lateral sliding plate b of the fork moves to the bottom of the drying rack to support the bottom of the drying rack, the baffle moves upward under the action of the lateral sliding plate b to limit the inlet and outlet ports of the drying rack.

[0010] Furthermore, the feeding unit is a four-axis motion system, including a transverse slide, a feeding longitudinal slide, a column, and a rotary disk. The column is movably mounted on a horizontal slide rail via the transverse slide. The feeding longitudinal slide is vertically mounted on the column via a lifting slide. A receiving mechanism is mounted on the feeding longitudinal slide via the rotary disk. The rotary disk reciprocates on the feeding longitudinal slide via a linear module. The receiving mechanism includes a receiving frame and a pushing cylinder mounted on the receiving frame. The two ends of the pushing cylinder are fixed above the receiving frame, and the pushing cylinder reciprocates along the guide rod between the two ends under the action of an air source. A feeding push plate is provided at the bottom of the pushing cylinder. The feeding push plate passes through a groove provided on the upper wall of the receiving frame. The bottom of the receiving frame is mounted on the upper surface of the rotary disk.

[0011] Furthermore, the unloading section includes an unloading frame, an unloading power mechanism, and an unloading platform located within the unloading frame. The unloading power mechanism is slidably mounted on a power mechanism slide rail, and the power mechanism slide rail is fixedly mounted on the unloading frame. The unloading power mechanism includes a power mechanism slide table, a slide plate, an unloading push plate, and an unloading motor. The unloading motor drives the slide plate to reciprocate along the power mechanism slide table via a lead screw. The unloading push plate is mounted on the slide plate and is L-shaped.

[0012] Furthermore, the fork unit includes a longitudinal fork slide slidably mounted on a ground rail. The longitudinal fork slide is driven by a longitudinal power unit to reciprocate along the ground rail. A fork lifting platform is mounted on the longitudinal fork slide, and a transverse sliding plate a is mounted on the fork lifting platform. The transverse sliding plate a is driven by a transverse power unit to achieve its reciprocating movement. A transverse sliding plate b is slidably mounted on the transverse sliding plate a, and the transverse sliding plate b is driven by a motor to reciprocate along the transverse sliding plate a.

[0013] Furthermore, the bottom of both the loading platform and the unloading platform is mounted on the support frame via a lifting mechanism, and the bottom of both the loading platform and the unloading platform is provided with several guide rods that pass through the support frame.

[0014] Furthermore, a positioning sensor is installed at the docking point between the receiving mechanism and the overhead rail, and anti-fall baffles are provided on the three hollowed-out sides of the receiving frame. These anti-fall baffles are driven by independent cylinders to slide up and down along the sides of the receiving frame.

[0015] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0016] (1). This invention effectively saves space in the entire drying line by rationally setting the positional relationship between the forks and the drying chamber, as well as the loading and unloading platforms, and by using bidirectional telescopic forks. At the same time, the number of drying chambers is set according to the drying time to maximize the utilization of space and time. By setting the top and bottom opening chamber doors, the opening and closing of the chamber doors are controlled by locking cylinders and combined with pneumatic pins. The downward opening method helps to prevent the chamber doors from falling down and colliding with the drying trays containing detonators during loading and unloading, thus preventing safety accidents. At the same time, it ensures the stability of the chamber doors when drying is carried out with the doors closed.

[0017] (2). This invention combines water circuits and insulation materials, uses a hot water station as the heat source for the water circuits, eliminates the potential safety risks of traditional electric radiation heating, and the direct contact between the water circuits and the inner wall of the box helps to improve the uniformity of heat transfer. The insulation materials help to reduce heat loss, and have the effect of slow heating process and constant temperature stability.

[0018] (3). By setting the drying rack as a double-layer structure, the ventilation holes help to improve the heating uniformity of the detonators inside the drying rack. At the same time, the positioning block and positioning pin are matched with the inspection sensor, which helps to determine whether the drying rack is in place and to position and limit the drying rack. By setting mechanical baffles at the inlet and outlet on both sides of the drying rack, when the drying rack is lifted by the fork, the mechanical baffles automatically move upward to block and limit the drying tray containing the detonators inside the drying rack, preventing displacement and falling.

[0019] (4). This invention sets up a feeding part with a four-axis motion system to realize the movement of the receiving mechanism in the horizontal, vertical, and rotational directions. At the same time, the feeding pusher plate is driven by the reciprocating movement of the pushing cylinder to push the drying tray containing detonators in the receiving frame to the drying rack. By setting a positioning sensor on the receiving mechanism, it is ensured that it is in position with the overhead rail when docking with the overhead rail. Then the overhead rail pushes the conveyed drying tray containing detonators into the receiving frame. At the same time, a fall protection baffle is set up, which helps to improve the stability of the receiving mechanism during operation and rotation and prevent the drying tray from slipping and falling.

[0020] (5) By setting up a feeding section, the present invention uses an L-shaped feeding pusher plate to move back and forth under the drive of the feeding motor to push the drying tray containing detonators into the conveyor belt in sequence, thereby realizing automated feeding, saving time and effort.

[0040] To address the limitations of existing technologies, this embodiment provides a technical solution. The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0041] This invention relates to a fully automated intelligent detonator drying line, primarily concerning the drying process in the production of detonators (8) for military applications. Because electronic detonators (8) are highly susceptible to explosion if struck or dropped during the drying process, the drying process demands extremely high safety standards. (See attached diagram.) Figure 1-2 The drying line includes a ceiling track, a loading section 1, a ground track 3, a forklift section 4, five drying chambers 5, an automatic temperature control system for maintaining a constant temperature within the drying chambers 5, and a unloading section 6. The ceiling track is responsible for transporting the drying trays 9 containing detonators 8 to the loading section 1 for docking. The ceiling track is equipped with a cylinder-driven mechanism to push the drying trays 9 to the loading section 1 (not shown in the attached diagram). The loading section 1 receives several drying trays 9 transported to a designated position by the ceiling track and pushes the drying trays 9 sequentially to the drying rack 2. A position sensor is installed at the docking point between the receiving mechanism 13 and the ceiling track. The position sensor can be a contact sensor. When the ceiling track touches the receiving mechanism 13, it indicates that the ceiling track has reached the correct position and the drying trays 9 can be pushed. The three open sides of the receiving frame 131 are equipped with anti-fall baffles. These anti-fall baffles are driven by independent cylinders and slide up and down along the sides of the receiving frame 131. When it is necessary to push the drying trays 9, the anti-fall baffles all descend to facilitate the pushing of the drying trays 9 into the receiving frame. Inside frame 131, when the pushing is completed and rotation is required, the anti-fall baffle rises to seal the space inside frame 131, preventing the drying tray 9 from shifting and falling during the movement and rotation. The fork part 4 is installed on the ground rail 3. The fork part 4 is used to transport the drying rack 2 to the drying box 5 for drying and to take out the drying rack 2 and transport it to the unloading part 6. The unloading part 6 is used to push the drying tray 9 in the drying rack 2 onto the conveyor belt 7 in sequence. The fork part 4 is a two-way telescopic fork. The fork part 4 is located between the drying box 5 and the unloading part 6 and the loading part 1. Specifically, three drying boxes 5 are in one row, two drying boxes 5, the unloading part 6 and the loading part 1 are in another row, and the ground rail 3 and the fork part 4 are located between the two rows of drying boxes 5. By reasonably setting the positional relationship between the fork part 4 and the drying box 5, as well as the loading platform 17 and the unloading platform 64, and by using a two-way telescopic fork, the space occupied by the entire drying line is effectively saved. At the same time, the number of drying boxes 5 is set according to the drying time, so as to maximize the utilization of space and time.

[0042] See appendix Figure 6 and 7The drying oven 5 is equipped with a vertically opening door 52. A silicone rubber sealing ring is provided on the side of the door 52 that contacts the drying oven 5. Slider blocks are provided at both the top and bottom ends of both sides of the door 52. These sliders slide within grooves in guide blocks 53 on the outer walls of the oven body. A locking cylinder 54 is installed on the outer wall 51 of the oven body. The locking cylinder 54 is fixed to the outer wall 51, and its power end is installed on the door 52. The action of the locking cylinder 54 drives the sliders on both sides of the door 52 to move up and down along the guide blocks 53, thereby causing the door 52 to move up and down to close and open. A pneumatic pin is also installed on the outer wall 51 of the oven body. This pneumatic pin is used to limit the movement of the door 52 when it is in the closed or open state. Specifically, when the door is closed, the upper part of the oven body below the door 52... The chamber is equipped with four pneumatic pins. The side of the chamber door 52 facing the chamber body has corresponding holes for the pneumatic pins. When the chamber door 52 is closed, the two holes at the bottom of the door 52 engage with the two pneumatic pins at the top for positioning. When the chamber door 52 is open, the four holes engage with the four pneumatic pins to position the door 52, preventing it from falling or rising during material loading or unloading, thus avoiding serious consequences. The chamber door 52 opens vertically, and the locking cylinder 54 controls its opening and closing in conjunction with the pneumatic pins. The downward opening mechanism helps prevent the door 52 from falling and colliding with the drying tray 9 containing the detonators 8 during material loading or unloading, thus preventing accidents. It also ensures the stability of the chamber door 52 when it is closed for drying. (See appendix) Figure 8 and 9 A water passage 57 is provided in the sealed cavity between the outer wall 51 and the inner wall 56 of the drying oven 5. The water passage 57 consists of several parallel water pipes connected in series. The inner cavity of the water pipe is in direct contact with the inner wall 56 and is welded to the inner wall 56. It is equivalent to the water passage 57 being separated from the inner cavity of the oven by only one layer of the inner wall 56. The cavity between the water passage 57 and the outer wall 51 is filled with thermal insulation material. The inlet and outlet of water channel 57 are connected to an external hot water supply station. A vacuum pump is connected inside the drying chamber 5. Temperature sensors are installed in the inner cavity of the drying chamber 5 and at the hot water outlet of the hot water supply station. The automatic temperature control system will alarm if the temperature exceeds the limit value. The door 52 of the drying chamber 5 is interlocked with the forks. This interlock is mainly controlled by a PLC program. When the door 52 is open, the forks 4 can perform feeding and discharging actions. When the door 52 is closed, the forks 4 cannot move. When the forks 4 are performing feeding and discharging actions, the door 52 is open and cannot be closed. Only when the forks 4 are reset can the door 52 be opened and closed. By setting up water channel 57 and using insulation materials in combination, and using the hot water supply station to increase the heat source for water channel 57, the potential safety risks of traditional electric radiation heating are eliminated. The direct contact between water channel 57 and the inner wall 56 of the chamber is conducive to improving the uniformity of heat transfer, and the insulation material helps to reduce heat loss, resulting in a slow heating process and stable constant temperature. See appendix. Figure 1and 3 The drying rack 2 is configured with a double-layer structure with five channels in each layer. Each channel is used for five drying trays 9. The side wall of the drying rack 2 is provided with several ventilation holes 21. The bottom of the drying rack 2 is provided with a positioning block. The positioning block cooperates with the positioning pins on the upper surface of the loading platform 17 and the unloading platform 64 to position and limit the drying rack 2. Both the loading platform 17 and the unloading platform 64 are provided with inspection sensors. The positioning pins and positioning blocks cooperate to position and limit the drying rack 2 after it is in place. The inspection sensors are used to monitor whether the drying rack 2 is in place. Mechanical baffles are installed at the inlet and outlet ports on both sides of the drying rack 2. These mechanical baffles are slidably inserted into shaft holes at the ends of the drying rack 2 via guide shafts on both sides. When the lateral sliding plate b 45 of the fork part 4 moves to the bottom of the drying rack 2 to support it, the mechanical baffles move upwards under the action of the lateral sliding plate b 45 to limit the inlet and outlet ports of the drying rack 2 (not shown in the attached diagram). Specifically, the mechanical baffles are two parallel flat plates arranged vertically, with both sides of the two flat plates fixedly connected to guide shafts. The drying rack 2 is designed as a rectangular structure with a double-layer structure. The ventilation holes 21 help to improve the heating uniformity of the detonators 8 inside the drying rack 2. The positioning blocks and positioning pins, as well as the inspection sensors, help to determine whether the drying rack 2 is in place and to position and limit the drying rack 2. Mechanical baffles are set at the inlet and outlet ports on both sides of the drying rack 2. When the drying rack 2 is lifted by the fork 4, the mechanical baffles automatically move upward to block and limit the drying tray 9 containing the detonators 8 inside the drying rack 2, preventing displacement and falling.

[0043] See appendix Figure 3 and 4The loading unit 1 is a four-axis motion system, including a transverse slide 11, a loading longitudinal slide 16, a column 14, and a rotary table 132. The column 14 is movably mounted on a horizontal slide rail 15 via the transverse slide 11. The loading longitudinal slide 16 is vertically mounted on the column 14 via a lifting slide 12. The reciprocating motion between the transverse slide 11 and the horizontal slide rail 15, and between the lifting slide 12 and the column 14, is achieved through linear modules. A receiving mechanism 13 is mounted on the loading longitudinal slide 16 via the rotary table 132. The rotary table 132 reciprocates on the loading longitudinal slide 16 via linear modules. The receiving mechanism 13 includes a receiving frame 131 and a pusher cylinder 134 mounted on the receiving frame 131. The two ends of the pusher cylinder 134 are fixed above the receiving frame 131, and the pusher cylinder 134 reciprocates along the guide rod 135 between the two ends under the action of an air source. A feeding pusher plate 133 is provided at the bottom of the feeding cylinder 134. The feeding pusher plate 133 passes through a sliding groove provided on the upper wall of the receiving frame 131. The bottom of the receiving frame 131 is installed on the upper surface of the rotating disk 132. By setting up the feeding part 1 with a four-axis motion system, the receiving mechanism 13 can move in the horizontal, vertical, and rotational directions. At the same time, the feeding pusher plate 133 is driven by the reciprocating movement of the feeding cylinder 134 to push the drying tray 9 containing the detonator 8 in the receiving frame 131 to the drying rack 2. By setting up a positioning sensor on the receiving mechanism 13, it is ensured that it is in position with the ceiling rail when docking. Then, the ceiling rail pushes the conveyed drying tray 9 containing the detonator 8 into the receiving frame 131. At the same time, an anti-fall baffle is set up to improve the stability of the receiving mechanism 13 during operation and rotation and to prevent the drying tray 9 from slipping and falling.

[0044] See appendix Figure 10-12 The unloading section 6 includes an unloading frame 61, an unloading power mechanism 62, and an unloading platform 64 located within the unloading frame 61. The unloading frame 61 consists of a square top frame and three legs. The unloading power mechanism 62 is slidably mounted on a power mechanism slide rail 63, which is fixedly mounted on the top frame of the unloading frame 61. The unloading power mechanism 62 includes a power mechanism slide 621, a slide plate 622, an unloading push plate 623, and an unloading motor 624. The unloading motor 624 drives the slide plate 622 to reciprocate along the power mechanism slide 621 via a lead screw. The unloading push plate 623 is mounted on the slide plate 622 and is L-shaped. By setting up the unloading section 6, the L-shaped unloading push plate 623 reciprocates under the drive of the unloading motor 624, thereby sequentially pushing the drying trays 9 containing detonators 8 in the drying rack 2 onto the conveyor belt 7, achieving automated unloading and saving time and effort.

[0045] See appendix Figure 5The fork unit 4 includes a longitudinal fork slide 41 slidably mounted on the ground rail 3. The longitudinal fork slide 41 is driven by a longitudinal power unit 43 to reciprocate along the ground rail 3. A fork lifting platform 46 is mounted on the longitudinal fork slide 41. The fork lifting platform 46 adopts a screw lifting mechanism. A transverse sliding plate a part 44 is mounted on the fork lifting platform 46. The transverse sliding plate a part 44 is driven by a transverse power unit 42 to achieve its reciprocating movement. A transverse sliding plate b part 45 is slidably mounted on the transverse sliding plate a part 44. The transverse sliding plate b part 45 is driven by a motor to reciprocate along the transverse sliding plate a part 44.

[0046] See appendix Figure 3 and 10 The bottom of the loading platform 17 and the unloading platform 64 are both mounted on the support frame 10 via a lifting mechanism. The bottom of the loading platform 17 and the unloading platform 64 are provided with several guide rods 135 that pass through the support frame 10. The lifting mechanism here adopts a conventional lifting platform, which is driven by a motor to lift the platform.

[0047] Working principle: When using this drying line for drying operations, the overhead rail transports the drying tray 9 containing the detonators 8 to the top of the feeding section 1. The overhead rail connects with the receiving mechanism 13, which pushes the drying tray 9 sequentially into the receiving frame 131 of the receiving mechanism 13. The receiving mechanism 13 descends along the column 14 and moves along the longitudinal sliding table 16 to the feeding platform 17. The receiving mechanism 13 rotates, and the pushing cylinder 134 actuates to push the drying tray 9 sequentially onto the drying rack. Inside section 2, after receiving the signal, the fork unit 4 moves along the ground rail 3 to the loading platform 17. The lateral sliding plate a part 44 and the lateral sliding plate b part 45 of the fork unit 4 move into the area above the loading platform 17 where the drying rack 2 is placed. The fork lifting platform 46 of the fork unit 4 rises to lift the drying rack 2. The lateral sliding plate a part 44 and the lateral sliding plate b part 45, as well as the ground rail 3 and the longitudinal sliding platform 41 of the forks work together to move the drying rack 2 to the outside of the door 52 of the drying chamber 5. The door 52 opens and moves downward. The fork unit 4 places the drying rack 2 onto the support block 55 inside the drying chamber 5. The support block 55 is equipped with a positioning sensor and a positioning pin, which cooperates with the positioning block at the bottom of the drying rack 2. Then, the fork lifting platform of the fork unit 4 lowers and moves out of the drying chamber 5. The door 52 closes under the action of the locking cylinder 54. The drying chamber 5 is evacuated and drying is carried out simultaneously. A water ring vacuum pump is selected. Since the gas compression in the water ring vacuum pump is isothermal, it can remove flammable and explosive gases. Since there is no exhaust valve or friction surface, it can remove dusty gases, condensable gases, and gas-water mixtures. After the drying chamber 5 dries the drying rack 2, the door 52 opens, and the fork unit 4 moves the drying rack 2 onto the unloading platform 64. The unloading power mechanism 62 of the unloading unit 6 drives the unloading push plate 623 to push the drying trays 9 inside the drying rack 2 onto the conveyor belt 7 in sequence, completing the entire drying operation.
