Description

Technical Field

[0001] This utility model relates to the field of material discharge technology for curing ovens, and in particular to an automatic material discharge device for a three-dimensional drying and curing oven. Background Technology

[0002] In the existing technology, most drying and curing ovens used for automatic drying and curing of products are electrically heated tunnel drying and curing ovens. Their feeding end and discharging end are basically designed as single-layer, open type. However, in long-term practical application, it has been found that this type of curing oven has the following problems: In order to facilitate the handling of materials and improve the drying and curing quality, the continuous tunnel oven design is relatively long. It is necessary to design a long curing oven body to meet the time requirements of material drying and curing. However, this inevitably increases the floor area of ​​the drying and curing oven, resulting in a large overall floor area of ​​the drying and curing oven. This not only makes it inconvenient to manage, but also increases the production cost accordingly. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an automatic material discharge device for a three-dimensional drying and curing oven. It can not only meet the design requirements of reducing the overall footprint of the curing oven, but also ensure stable production and improve product quality, thereby reducing the production cost of the user and effectively solving the problems in the background technology.

[0004] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0005] An automatic material discharge device for a three-dimensional drying and curing oven includes a drying and curing oven body. A discharge port is provided on the upper part of the oven wall at the discharge end of the drying and curing oven body. A lifting mechanism is installed on the drying and curing oven body at the position corresponding to the discharge port, and a material picking mechanism is installed on the drying and curing oven body at the position corresponding to the outer side of the discharge port.

[0006] The lifting mechanism includes linear slide rails, a drive sprocket, a drive shaft, a driven shaft A, a lifting chain, a bearing seat A, a drive motor, a driven sprocket, and a lifting slider. Both the drive shaft and driven shaft A are rotatably mounted inside the drying and curing oven body via bearing seat A. The drive shaft has a drive sprocket, and driven shaft A has a driven sprocket. The drive sprocket is connected to the driven sprocket via the lifting chain. At least two linear slide rails are provided, symmetrically mounted on the inner wall of the drying and curing oven body. The lifting slider is slidably connected to the linear slide rails. A material support lifting plate is fixed to the lifting slider, and the lifting slider is fixed to the lifting chain. The material support lifting plate supports stacked workpiece trays. A drive motor is mounted on the side of the drying and curing oven body, and the output shaft of the drive motor is fixedly connected to the end of the drive shaft.

[0007] Furthermore, the material handling mechanism includes a fixed frame, a workpiece tray, a fixed guide post, a bearing seat B, a driven shaft B, a multi-ribbed pulley, a multi-ribbed belt, a reducer, a motor, a secondary cylinder connecting plate, a workpiece tray support fork, and a secondary cylinder. The fixed frame is equipped with a drive device and a fixed guide post. The reducer and motor are both mounted on the fixed frame. The driven shaft B is rotatably mounted on the fixed frame via the bearing seat B. A multi-ribbed pulley is fixed to the driven shaft B. Both the driven shaft B and the output shaft of the reducer are equipped with multi-ribbed pulleys, which are connected by a multi-ribbed belt drive. The secondary cylinder connecting plate is fixed to the multi-ribbed belt, and the secondary cylinder is mounted on the secondary cylinder connecting plate. The workpiece tray support fork is fixed to the lever of the secondary cylinder, and the workpiece tray is placed on the workpiece tray support fork.

[0008] Furthermore, the lower part of the fixing frame is provided with a mechanical conveying device for receiving the workpiece tray, and the mechanical conveying device is arranged perpendicularly to the workpiece tray.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic material discharge device for a three-dimensional drying and curing oven has the following advantages:

[0010] 1. Its overall structure is compact, easy to manufacture, and easy to operate.

[0011] 2. The drying and curing oven is designed as a three-dimensional structure with workpiece trays inside the oven. Multiple workpiece trays are stacked together, allowing them to be dried and cured in a vertically overlapping state within the oven. Since this method only requires the workpiece trays to be stacked and moved a short distance within the oven to achieve the drying and curing effect of traditional drying and curing ovens, the length of the oven body can be greatly shortened, reducing the floor space and consequently reducing production costs.

[0012] 3. Its discharge device adopts a lifting mechanism inside the curing furnace for lifting the stacked material trays. It can lift the stacked material trays step by step, so as to meet the requirement that each material tray corresponds to the discharge port. At the same time, a discharge mechanism is set outside the curing furnace for inserting and removing the material trays corresponding to the discharge ports. It can remove the individual material trays corresponding to the discharge ports one by one, so as to meet the requirement of removing the material trays that make up the stacked material trays one by one from the furnace according to the first-in-first-out material removal requirement.

[0013] 4. Its discharge device can conveniently and quickly remove the material trays one by one while meeting the time requirements for drying and curing and effectively shortening the length of the curing furnace.

Detailed Implementation

[0017] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0018] Please see Figure 1-2 This embodiment provides a technical solution: an automatic material discharge device for a three-dimensional drying and curing oven, including a drying and curing oven body 1, a discharge port 2 is provided on the upper part of the oven wall at the discharge end of the drying and curing oven body 1, a lifting mechanism is installed on the drying and curing oven body 1 at the position corresponding to the discharge port 2, and a material picking mechanism is installed on the drying and curing oven body 1 at the position corresponding to the outer side of the discharge port 2.

[0019] The lifting mechanism includes linear slide rails 4, a drive sprocket 6, a drive shaft 7, a driven shaft A12, a lifting chain 5, a bearing housing A8, a drive motor 9, a driven sprocket 13, and a lifting slider 11. Both the drive shaft 7 and the driven shaft A12 are rotatably mounted inside the drying and curing oven body 1 via the bearing housing A8. The drive shaft 7 has a drive sprocket 6, and the driven shaft A12 has a driven sprocket 13. The drive sprocket 6 is connected to the driven sprocket 13 via the lifting chain 5. At least two linear slide rails 4 are provided, symmetrically mounted on the inner wall of the drying and curing oven body 1. Block 11 is slidably connected to the linear slide rail 4. The material lifting plate 10 is fixed on the lifting slider 11, and the lifting slider 11 is fixed on the lifting chain 5. The material lifting plate 10 supports the stacked workpiece tray stack 3. A drive motor 9 is installed on the side of the drying and curing furnace body 1. The output shaft of the drive motor 9 is fixedly connected to the end of the drive shaft 7. In the initial position, the material lifting plate 10 is below the discharge port 2 and close to the bottom of the drying and curing furnace body 1. At this time, the workpiece tray stack 3 has not yet reached the discharge station. Then, when the workpiece tray stack 3 reaches this position... After the workstation is in place, the drive motor 9 starts, driving the drive shaft 7 to rotate. The drive sprocket 6 on the drive shaft 7 is driven by the driven sprocket 13 on the driven shaft A12 via the lifting chain 5. The chain 5 drives the slider 11 to slide along the linear slide rail 4, thereby driving the material lifting plate 10 and the lifting slider 11 to move upward. As the material lifting plate 10 rises, the workpiece pallet stack 3 on the discharge station is slowly lifted. When the uppermost workpiece pallet 15 of the stack reaches the designed position of the discharge port 2, the drive motor 9 stops working, and the entire workpiece pallet stack is completed. The unit 3 stops rising and waits for the material handling mechanism to remove the material from the furnace. Its overall structure is compact, easy to manufacture, and easy to operate. The drying and curing furnace is designed as a three-dimensional structure with workpiece trays inside the furnace. Multiple workpiece trays are stacked together, so that multiple trays can be dried and cured in a vertically overlapping state inside the curing furnace. Since this method only requires the workpiece trays inside the furnace to move a short distance to achieve the drying and curing effect of traditional drying and curing furnaces, it can greatly shorten the furnace body length, reduce the floor space, and correspondingly reduce production costs.

[0020] The material handling mechanism includes a fixed frame 14, a workpiece tray 15, a fixed guide post 16, a bearing seat B17, a driven shaft B18, a multi-ribbed pulley 19, a multi-ribbed belt 20, a reducer 21, a motor 22, a secondary cylinder connecting plate 23, a workpiece tray support fork 24, and a secondary cylinder 25. The fixed frame 14 is equipped with a drive unit and a fixed guide post 16. The reducer 21 and motor 22 are both mounted on the fixed frame 14. The driven shaft B18 is rotatably mounted on the fixed frame 14 via the bearing seat B17. The multi-ribbed pulley 19 is fixed to the driven shaft B18. The driven shaft B18 and the reducer... Multi-ribbed pulleys 19 are fixed on the output shaft of motor 21. Two multi-ribbed pulleys 19 are connected by a multi-ribbed belt 20. The secondary cylinder connecting plate 23 is fixed on the multi-ribbed belt 20. The secondary cylinder 25 is mounted on the secondary cylinder connecting plate 23. The workpiece tray support fork 24 is fixed on the lever of the secondary cylinder 25. The workpiece tray 15 is placed on the workpiece tray support fork 24. Both the secondary cylinder connecting plate 23 and the workpiece tray support fork 24 are slidably connected to the fixed guide post 16. The output shaft of motor 22 is fixedly connected to the input shaft of reducer 21. The lower part of the fixed frame 14 is equipped with a workpiece receiving mechanism. The mechanical conveying device of the material tray 15 is vertically aligned with the workpiece material tray 15. When the furnace door is opened, the motor 22 on the material handling mechanism starts, driving the reducer 21. The multi-ribbed pulley 19 on the reducer 21 and the multi-ribbed pulley 19 on the driven shaft B18 are connected by a multi-ribbed belt 20. The multi-ribbed belt 20 drives the secondary cylinder connecting plate 23 to slide along the fixed guide post 16. At this time, the workpiece material tray support fork 24 in the initial position moves into the furnace. After the multi-ribbed belt 20 reaches its stroke, the drive motor 22 stops working, and the secondary cylinder 25 starts to extend. When the lever end moves the workpiece tray support fork 24 into the furnace until the fork is inserted into the designed position below the workpiece tray 15, the drive motor 9 reverses. At this time, the entire workpiece tray stacking set 3 descends as a whole. Due to the obstruction of the workpiece tray support fork 24, the uppermost workpiece tray 15 is blocked by the workpiece tray support fork 24. The other workpiece tray stacking sets 3 continue to descend until the uppermost workpiece tray 15 is removed from the entire workpiece tray stacking set 3. At this time, the drive motor 9 stops working, and the workpiece tray stacking set 3 stops descending and stays at this position.

[0021] Next, the motor 22 starts in reverse, and the workpiece tray support fork 24 begins to move out of the furnace. The workpiece tray 15 on it moves out of the furnace together. After reaching the designed discharge position outside the furnace, the motor 22 stops working. At this time, the movement of the workpiece tray 15 also stops. Then it is supported by the mechanical mechanism outside the furnace, and the secondary cylinder 25 retracts, so that the workpiece tray support fork 24 returns to the initial position and leaves the workpiece tray 15. Then the workpiece tray 15 is taken away by the mechanical conveying device outside the furnace, freeing up its position at the discharge port 2. At this time, the first workpiece tray 15 has completed its process of being discharged from the furnace to the outside of the furnace.

[0022] Next, the second, third, and Nth workpieces will be unloaded from the furnace following the same process until the last workpiece tray 15 of the entire workpiece tray stack set 3 is unloaded. At this point, the drive motor 9 in the lifting device will start and reverse, driving the material lifting plate 10 back to the starting position. At this time, the workpiece tray fork 24 in the material handling mechanism will be retracted by the secondary cylinder 25. At this point, the unloading of the workpiece tray stack set 3 is completed, and the unloading station in the furnace will be vacated to wait for the arrival of the next workpiece tray stack set 3. This cycle will continue to perform automatic unloading.

[0023] At this point, the unloading of the workpiece tray stack 3 is completed, and the unloading station in the furnace is vacated to await the arrival of the next workpiece tray stack 3. This utility model device continuously performs automatic unloading operations. Its unloading device employs a lifting mechanism inside the curing furnace to elevate the tray stack, which can lift the tray stack step by step, thus ensuring that each tray corresponds to a different discharge port. Simultaneously, an unloading mechanism outside the curing furnace is used to insert and remove trays corresponding to their respective discharge ports, allowing each individual tray to be removed one by one. This satisfies the requirement of removing the workpieces from the furnace according to the first-in, first-out (FIFO) principle. The unloading device can conveniently and quickly remove trays one by one while meeting the drying and curing time requirements and effectively shortening the length of the curing furnace. It not only meets the design requirement of reducing the overall footprint of the curing furnace but also ensures stable production and improves product quality, ultimately reducing the user's production costs.

[0024] The working principle of the automatic material discharge device for a three-dimensional drying and curing oven provided by this utility model is as follows: The material lifting plate 10 is initially positioned below the discharge port 2, close to the bottom of the drying and curing oven body 1. At this time, the workpiece tray stack 3 has not yet reached the discharge station. Then, when the workpiece tray stack 3 reaches this station, the drive motor 9 starts, driving the drive shaft 7 to rotate. The drive sprocket 6 on the drive shaft 7 is driven by the driven sprocket 13 on the driven shaft A12 via the lifting chain 5. The chain 5 drives the slider 11 to slide along the linear slide rail 4, thereby driving the material lifting plate 10 and the lifting slider 11 to move upwards. As the material lifting plate 10 rises, the workpiece tray stack 3 at the discharge station is slowly lifted. When the uppermost workpiece tray 15 of the stack reaches the designed position of the discharge port 2, the drive motor 9 stops working, and the entire workpiece tray stack 3 stops rising, waiting for the material handling mechanism to remove the material from the oven. At this time, the oven door opens, and the material handling mechanism... The motor 22 starts and drives the reducer 21. The multi-ribbed pulley 19 on the reducer 21 and the multi-ribbed pulley 19 on the driven shaft B18 are connected by a multi-ribbed belt 20. The multi-ribbed belt 20 drives the secondary cylinder connecting plate 23 to slide along the fixed guide post 16. At this time, the workpiece tray support fork 24 in the initial position moves into the furnace. After the multi-ribbed belt 20 reaches its stroke, the drive motor 22 stops working, the secondary cylinder 25 starts and extends, and its lever end drives the workpiece tray support fork 24 to continue moving into the furnace. The fork moves inward until it is inserted into the designed position below the workpiece tray 15. At this time, the drive motor 9 reverses, and the entire workpiece tray stacking set 3 descends as a whole. Due to the obstruction of the workpiece tray fork 24, the uppermost workpiece tray 15 is blocked by the workpiece tray fork 24. The other workpiece tray stacking sets 3 continue to descend until the uppermost workpiece tray 15 is removed from the entire workpiece tray stacking set 3. At this time, the drive motor 9 stops working, and the workpiece tray stacking set 3 stops descending and stays at this position.

[0025] Next, the motor 22 starts in reverse, and the workpiece tray support fork 24 begins to move out of the furnace. The workpiece tray 15 on it moves out of the furnace together. After reaching the designed discharge position outside the furnace, the motor 22 stops working. At this time, the movement of the workpiece tray 15 also stops. Then it is supported by the mechanical mechanism outside the furnace, and the secondary cylinder 25 retracts, so that the workpiece tray support fork 24 returns to the initial position and leaves the workpiece tray 15. Then the workpiece tray 15 is taken away by the mechanical conveying device outside the furnace, freeing up its position at the discharge port 2. At this time, the first workpiece tray 15 has completed its process of being discharged from the furnace to the outside of the furnace.

[0026] Next, the second, third, and Nth workpieces will be unloaded from the furnace following the same process until the last workpiece tray 15 of the entire workpiece tray stack set 3 is unloaded. At this point, the drive motor 9 in the lifting device will start and reverse, driving the material lifting plate 10 back to the starting position. At this time, the workpiece tray fork 24 in the material handling mechanism will be retracted by the secondary cylinder 25. At this point, the unloading of the workpiece tray stack set 3 is completed, and the unloading station in the furnace will be vacated to wait for the arrival of the next workpiece tray stack set 3. This cycle will continue to perform automatic unloading.

[0027] At this point, the unloading of the workpiece tray stack 3 is completed, and the unloading station in the furnace is emptied to await the arrival of the next workpiece tray stack 3; the process is repeated continuously by this utility model device to perform automatic unloading.
