Description

Technical Field

[0001] The invention relates to the technical field of aluminum foil drying devices, and in particular to a drying device and a drying method for processing medicinal aluminum foil. Background Art

[0002] Medicinal aluminum foil is a kind of aluminum foil specially used for drug packaging. Based on its good barrier properties, heat sealing properties and sealing properties, it can have a good barrier effect on various gases and light, and has good moisture-proof and fragrance-preserving functions.

[0003] Chinese patent CN216347584U discloses a drying device for processing medicinal aluminum foil, which uses a first heat energy tube to dry the inside of a drying box, and a first motor drives a centrifugal fan to rotate, so that the drying effect is better. Through a conveying mechanism, the aluminum foil can be conveyed using a transmission roller during drying, thereby avoiding the breakage of the aluminum foil during the drying process.

[0004] When the above device is in use, the medicinal aluminum foil is allowed to pass through the drying box, and the two sides of the aluminum foil are dried by setting up multiple second heat energy tubes and centrifugal fans. However, in actual use, since there is a distance between the inner wall of the drying box and the side of the aluminum foil, this distance increases as the width of the aluminum foil decreases, so that the airflows on the upper and lower sides of the aluminum foil can disturb each other, which is not conducive to maintaining the stability of the aluminum foil. In addition, since the size of the space where the aluminum foil is located cannot be changed, the energy required to maintain a constant temperature in the drying box will not be reduced due to the reduction of the width of the aluminum foil, which is not conducive to energy saving. In summary, there is still room for improvement in the above device.

[0005] Therefore, it is necessary to provide a drying device and a drying method for processing medicinal aluminum foil to solve the above-mentioned technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a drying device and a drying method for processing medicinal aluminum foil, so as to solve the problem that when the existing device proposed in the above background technology is used, the medicinal aluminum foil is allowed to pass through a drying box, and a plurality of second heat energy tubes and a centrifugal fan are arranged to dry both sides of the aluminum foil. However, in actual use, there is a distance between the inner wall of the drying box and the side edge of the aluminum foil, and this distance increases as the width of the aluminum foil decreases, so that the airflows on the upper and lower sides of the aluminum foil can disturb each other, which is not conducive to maintaining the stability of the aluminum foil.

When the partition drives the rotating shaft to move relative to the guide frame, the rotating shaft can rotate on itself and disengage from the stop assembly. When the rotating shaft remains stable relative to the guide frame, the stop assembly is clamped with the rotating shaft, so that when the partition moves to the side of the aluminum foil, the stop assembly can contact the outer wall of the box body.

[0013] As a further solution of the present invention: a collar is provided on the outer fixing sleeve of the rotating shaft, a rotation speed sensor is installed on the collar, and the rotation speed sensor is connected to the second electromagnet.

[0016] As a further solution of the present invention: the slider and the spoiler are configured as an inverted T-shape as a whole, and the top surfaces of the spoiler and the slider are flush with the top surface of the guide frame.

[0017] A method for drying using the above-mentioned drying device for processing medicinal aluminum foil comprises the following steps: inserting one end of the aluminum foil into a box body from an inlet slot and passing through the box body from an outlet slot; driving the pressure strip to move downward so that the aluminum foil is pressed tightly between the pressure strip and the guide frame; driving the partition to approach the aluminum foil, during which the rotating shaft moves synchronously with the partition, when the rotating shaft stops moving, the stop block is engaged with the rotating shaft, and when the partition moves to the side of the aluminum foil, the stop block contacts the outer wall of the box body.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: this device, through the setting of the stop block, utilizes the clamping connection between the stop block, the positioning rod and the sliding rod, so that when the partition moves to the side of the aluminum foil, the stop block can be placed on the side wall of the box body, thereby limiting the movement of the aluminum foil, thereby ensuring that the partition can be stably placed on both sides of the aluminum foil, and when the aluminum foil is not in the center position of the inlet slot or the outlet slot, this device can also drive the two partitions to move to the side of the aluminum foil. The specific beneficial effects are as follows: on the one hand, the lateral space where the aluminum foil is located can be minimized. Due to the reduction in space, more energy is saved in the process of controlling temperature and wind speed. On the other hand, because the partition is close to the aluminum foil, the airflow above and below the aluminum foil will not cause major interference, so that the stability of the aluminum foil can be maintained as much as possible, which is beneficial to the drying of the surface coating of the aluminum foil.

DETAILED DESCRIPTION

[0031] like Figure 1-Figure 4 As shown, a drying device and drying method for processing medicinal aluminum foil include a box body 1, and the left and right sides of the box body 1 are respectively provided with an inlet groove 101 and an outlet groove 102, and the top and bottom ends of the box body 1 are respectively provided with an air distribution pipe 8, the air distribution pipe 8 passes through the box body 1 as a whole and is fixedly matched therewith, and a guide pipe is connected and arranged on the top surface of the air distribution pipe 8, so that the external hot air can enter the box body 1 through the air distribution pipe 8 to dry the aluminum foil 3. In actual use, two conveying rollers 2 are arranged on one side of the inlet groove 101, and the two conveying rollers 2 are arranged opposite to each other. Specifically, the conveying rollers 2 can be driven by an external power mechanism, refer to Fig.10 As shown, a plurality of support rollers 28 are evenly arranged in the box body 1. During the drying operation, the staff inserts one end of the aluminum foil 3 between the two conveying rollers 2. The friction force of the two conveying rollers 2 on the aluminum foil 3 can drive the aluminum foil 3 to extend into the box body 1, so as to reach the outlet groove 102 of the box body 1 through the support rollers 28 and finally pass through the box body 1. At this time, the hot air discharged by the air distribution duct 8 can dry the coating on the surface of the aluminum foil 3.

[0032] like Figure 2-Figure 8As shown, a guide frame 14 is provided in the box body 1, and the bottom surfaces of the introduction groove 101 and the outlet groove 102 are on the same horizontal plane as the top surface of the guide frame 14. Through this structure, the aluminum foil 3 entering the box body 1 can pass through the top surface of the guide frame 14 and contact the top surface of the guide frame 14. A pressure strip 15 is provided above the guide frame 14. In actual use, the aluminum foil 3 passes between the pressure strip 15 and the guide frame 14, and the pressure strip 15 can be used to press the aluminum foil 3 onto the guide frame 14;

[0033] Furthermore, partitions 16 are provided at both ends of the guide frame 14, and the partitions 16 can slide relative to the box body 1, and a notch 29 is provided at the center of the partition 16, so that the partition 16 can slide to the outside of the guide frame 14 and the pressure strip 15, and a rotating shaft 5 is provided at the partition 16. Specifically, one end of the rotating shaft 5 is slidably matched with the guide frame 14, and the other end of the rotating shaft 5 is provided with a stopper assembly matched with the box body 1. In actual use, when the partition 16 drives the rotating shaft 5 to move relative to the guide frame 14, the rotating shaft 5 can rotate by itself and disengage from the stopper assembly. After the guide frame 14 remains stable, the stop assembly is engaged with the rotating shaft 5. At this time, when the partition 16 moves to the vicinity of the aluminum foil 3, the stop assembly moves to the outer wall of the box body 1, thereby limiting the movement of the partition 16. In summary, through this device, the partition 16 can be adjusted according to the width of the aluminum foil 3 and its position in the box body 1, so that the partition 16 can slide to the positions on both sides of the aluminum foil 3. On the one hand, it can reduce the space where the aluminum foil 3 is located, which is beneficial to saving energy. On the other hand, it can minimize the problem of shaking of the aluminum foil 3 caused by the relative flow of gas on the upper and lower sides of the aluminum foil 3.

[0034] Reference Figure 3-Figure 6 As shown, the guide frame 14 has a hollow structure inside, and a through guide groove 1401 is provided on the top surface of the guide frame 14. A spoiler 19 is fixedly provided inside the guide frame 14, and the spoiler 19 is located at the center of the guide frame 14.

[0035] Furthermore, sliders 18 are slidably arranged on both sides of the spoiler 19 in the guide frame 14, and the sliders 18 are sealed with the guide frame 14. The sliders 18 and the spoiler 19 are integrally arranged in an inverted T shape, and the top surfaces of the spoiler 19 and the sliders 18 are flush with the top surface of the guide frame 14, and the end of the rotating shaft 5 close to the slider 18 is rotatably connected to the slider 18 through a bearing. In actual use, when the aluminum foil 3 passes through between the pressure strip 15 and the guide frame 14 and the pressure strip 15 holds the aluminum foil 3 When pressed against the guide frame 14, the slider 18 can only slide within the distance between the inner end surface of the guide frame 14 and the side of the aluminum foil 3, that is, when the slider 18 slides within the distance between the side of the aluminum foil 3 and the inner end surface of the guide frame 14, the gas in the guide frame 14 can be discharged through the guide groove 1401, and when the slider 18 slides to the bottom of the aluminum foil 3, the gas in the guide frame 14 is difficult to be discharged. At this time, the movement of the slider 18 will encounter greater resistance, so that the slider 18 can stay in the guide frame 14.

[0036] In order to be able to drive the rotating shaft 5 to rotate, the present solution provides a spiral limit groove 502 on the outer circumferential surface of the rotating shaft 5, and the end of the guide frame 14 provides a through hole so that the rotating shaft 5 can pass through the through hole. Specifically, a limit block 23 that slidably cooperates with the limit groove 502 is fixedly provided on the inner wall of the through hole. Through this structure, when the rotating shaft 5 moves in the horizontal direction relative to the guide frame 14, the cooperation between the limit block 23 and the limit groove 502 can cause the rotating shaft 5 to rotate.

[0037] The stopper assembly includes a stopper block 4, which is located outside the box body 1, and a positioning rod 6 is fixedly installed on the outer wall of the box body 1. The positioning rod 6 and the rotating shaft 5 pass through the stopper block 4 and slide with the stopper block 4. Figure 3-Figure 5 As shown, an insertion rod 22 is elastically mounted on the stop block 4, and an annular positioning groove 601 is provided on the outer circumference of the positioning rod 6, and a plurality of annular clamping grooves 501 are evenly provided on the outer circumference of the rotating shaft 5. The insertion rod 22 cooperates with the positioning groove 601 or the clamping groove 501, so that the stop block 4 can be clamped with the positioning rod 6 or the rotating shaft 5;

[0038] Furthermore, a boss 21 is fixedly provided on the outer side of the insertion rod 22, and the boss 21 is made of iron, and a second electromagnet 20 matching the boss 21 is installed on the stop block 4. When the second electromagnet 20 is in an energized state, the suction force of the second electromagnet 20 on the boss 21 enables the insertion rod 22 to move downward, so that the bottom end of the insertion rod 22 can be inserted into the slot 501, so that the stop block 4 and the rotating shaft 5 are mutually engaged. Similarly, when the second electromagnet 20 is in a de-energized state, the insertion rod 22 will pop up, so that the top end of the insertion rod 22 is inserted into the positioning slot 601.

[0039] In actual use, in order to control the second electromagnet 20, the present solution is provided with a collar 17 on the outer fixed sleeve of the rotating shaft 5, and the collar 17 is located on the side of the partition 16 away from the guide frame 14. As one of the embodiments for controlling the second electromagnet 20, a speed sensor can be installed at the collar 17 to monitor the rotation of the collar 17, and the speed sensor is connected to the second electromagnet 20. Specifically, a single chip microcomputer or a controller such as a PLC can be installed between the speed sensor and the second electromagnet 20. Specifically, when the partition 16 drives the rotating shaft 5 to move relative to the guide frame 14, the rotating shaft 5 can rotate, and when the speed sensor detects this signal, the second electromagnet 20 can be controlled to be in a power-off state, and at this time, the blocking block 4 is in a state of being engaged with the positioning rod 6;

[0040] In order to control another embodiment of the second electromagnet 20, a counterweight block 24 can be elastically installed on the ring 17, and a detection unit 25 can be installed on the inner side of the counterweight block 24 on the ring 17. The detection unit 25 can be a pressure sensor. Similarly, this pressure sensor needs to be connected to the second electromagnet 20. Specifically, when the ring 17 rotates with the rotating shaft 5, the counterweight block 24 is affected by the centrifugal force and can move outward relative to the ring 17, so that the counterweight block 24 is out of contact with the detection unit 25, so that the second electromagnet 20 can be in a power-off state.

[0041] In actual use, the aluminum foil 3 is fed into the box body 1 through the introduction slot 101, so that the aluminum foil 3 passes between the pressure strip 15 and the guide frame 14 and finally passes through the outlet slot 102 to pass through the box body 1. At this time, the aluminum foil 3 can be pressed against the guide frame 14 by the pressure strip 15, and then the partition 16 can be released so that the partition 16 can move toward the center of the box body 1. During the movement of the partition 16, the rotating shaft 5 can push the slider 18 to slide along the guide frame 14;

[0042] Specifically, if the width of the aluminum foil 3 matches the width of the inlet groove 101 and the outlet groove 102, the aluminum foil 3 is in the middle position of the guide frame 14, and the side of the aluminum foil 3 is aligned with the end face of the guide groove 1401. In this case, the slider 18 will compress the gas in the guide frame 14 during the initial movement, so that the slider 18 will stop moving after moving a short distance. During the period when the slider 18 moves with the rotating shaft 5, the rotating shaft 5 can be driven to rotate through the cooperation of the limit block 23 and the limit groove 502. According to the above description, when the rotating shaft 5 rotates, the second electromagnet 20 is in a power-off state, so that the insertion rod 22 can bounce upward, and when the top end of the insertion rod 22 is inserted into the positioning groove 601, the stop block 4 is engaged with the positioning rod 6, so that when the partition 16 drives the rotating shaft 5 to move in the horizontal direction, it will not drive the stop block 4 to move. When the slider 18 stops sliding, the rotating shaft 5 stops rotating. At this time, the second electromagnet 20 is in an energized state, so that the bottom end of the insertion rod 22 can be inserted into the annular slot 501 through the suction force of the second electromagnet 20 on the boss 21. At this time, the stop block 4 is engaged with the rotating shaft 5. Subsequently, when the pressure strip 15 is driven to move upward and away from the aluminum foil 3, the gas in the guide frame 14 can be completely discharged through the guide groove 1401, so that the partition 16 can move again. When the partition 16 moves to the end of the pressure strip 15 and the guide frame 14 and is located on one side of the aluminum foil 3, the rotating shaft 5 drives the stop block 4 to move to the outer wall of the box body 1 and fits with the outer wall of the box body 1, so that the movement of the partition 16 is limited by the stop block 4. At this point, the partition 16 moves to the side of the aluminum foil 3 and minimizes the space where the aluminum foil 3 is located.

[0043] Similarly, when the width of the aluminum foil 3 is smaller than the width of the inlet groove 101 and the outlet groove 102, when the pressure strip 15 presses the aluminum foil 3 against the top of the guide frame 14, the distance between the side of the aluminum foil 3 and the end face of the guide groove 1401 is in an open state. At this time, when the partition 16 is released so that the partition 16 drives the shaft 5 to move in the horizontal direction, the shaft 5 can drive the slider 18 to move the distance from the side of the aluminum foil 3 to the end face of the guide groove 1401, and during the movement, according to the above description, when the shaft 5 moves, the stop block 4 is engaged with the positioning rod 6, so that the shaft 5 cannot drive the stop block 4 to move. The stop block 4 moves synchronously, and when the slider 18 moves to the bottom of the aluminum foil 3, it will gradually stop moving. At this time, the stop block 4 can be engaged with the rotating shaft 5. At this point, the distance that the slider 18 moves relative to the aluminum foil 3 is roughly equal to the distance that the stop block 4 moves relative to the rotating shaft 5. Therefore, when the pressure strip 15 moves upward and away from the aluminum foil 3, the partition 16 can drive the rotating shaft 5 and the slider 18 at one end of the rotating shaft 5 to move again, and when the partition 16 moves to the side of the aluminum foil 3, the stop block 4 can reach the side wall of the box 1 and limit the partition 16, so as to keep the partition 16 stably placed on the side of the aluminum foil 3.

[0044] In summary, this device, by setting up the stop block 4, utilizes the clamping connection between the stop block 4 and the positioning rod 6 and the sliding rod 7, so that when the partition 16 moves to the side of the aluminum foil 3, the stop block 4 can be placed on the side wall of the box body 1, thereby limiting the movement of the aluminum foil 3, so as to ensure that the partition 16 can be stably placed on both sides of the aluminum foil 3, and when the aluminum foil 3 is not in the center position of the inlet groove 101 or the outlet groove 102, this device can also drive the two partitions 16 to move to the side of the aluminum foil 3. The specific beneficial effects are as follows: on the one hand, the lateral space where the aluminum foil 3 is located can be minimized. Due to the reduction in space, more energy is saved in the process of controlling temperature and wind speed. On the other hand, because the partition 16 is close to the aluminum foil 3, the airflow above and below the aluminum foil 3 will not cause major interference, so that the stability of the aluminum foil 3 can be maintained as much as possible, which is beneficial to the drying of the surface coating of the aluminum foil 3.

[0045] like Figure 1-Figure 3 As shown, mounting plates are provided at both ends of the conveying roller 2, and a connecting shaft is fixedly provided on the end surface of the conveying roller 2, the connecting shaft passes through the mounting plate and is rotatably connected to the mounting plate.

Through this structure, when the first electromagnet 11 is in an energized state, it can generate suction on the end cover, thereby driving the pressure strip 15 to move downward through the vertical rod 9.

[0047] A slide bar 7 is fixedly mounted on the outer surface of the partition 16, and a baffle is fixedly arranged at one end of the slide bar 7 away from the partition 16.

Furthermore, a third electromagnet 27 is fixedly installed on the inner end surface of the fixed frame 12, and a second spring is fixedly arranged between the third electromagnet 27 and the limit rod 26. In the initial state, one end of the limit rod 26 is inserted into the limit hole 1601 to limit the partition 16. After the first electromagnet 11 is controlled to make the pressure strip 15 press the aluminum foil 3, the staff can control the third electromagnet 27 to be in an energized state to move one end of the limit rod 26 out of the limit hole 1601, so that the first spring can push the partition 16 to move in the direction close to the aluminum foil 3.
