Description

Technical Field

[0001] The invention belongs to the technical field of automobile ceilings, in particular to a convection drying device for producing automobile ceilings. Background Art

[0002] Car ceilings, also known as car roof interiors, are materials covering the top of the vehicle. During the production and processing of car ceilings, some materials or additives containing moisture may be used. Drying the car ceiling helps to remove these moisture and volatiles to prevent them from causing problems in subsequent processing.

[0003] The patent with announcement number CN218097090U discloses a car ceiling drying device, including a base, the outer wall of the base is fixedly connected with a leg column, the outer wall of the base is fixedly connected with a device body, the outer wall of the device body is fixedly connected with a connecting block, the outer wall of the connecting block is fixedly connected with a hot air box, the inner wall of the hot air box is fixedly connected with a heating block, the outer wall of the hot air box is fixedly connected with a support frame, the outer wall of the support frame is fixedly connected with a first motor, the output shaft of the first motor is fixedly connected with a heat push fan through a coupling, the inner wall of the hot air box is fixedly connected with a ventilation net, one side of the hot air box is fixedly connected with a drying pipe, the inner wall of the drying pipe is fixedly connected with a support rod. The patent enables the device to dry the car ceiling, enables the drying of the car ceiling to be more comprehensive and effective, and can transmit the processed car ceiling.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The car roof is placed on the drying flat net, and then the hot air is used to dry the car roof. However, in some cases, in order to improve the drying efficiency, multiple car roofs need to be dried at one time. When multiple car roofs are placed on the drying flat net manually, it is easy for the car roofs to contact and fit each other, resulting in the car roofs covering each other, which in turn affects the drying effect. In addition, in order to dry multiple car roofs at the same time, the placement area of ​​the drying flat net will be set too large. When the placement area of ​​the drying flat net is large, it is not easy for workers to place the car roof to the inner area of ​​the drying flat net. Therefore, in order to avoid the car roofs covering each other and affecting the drying effect, it is also more laborious to deliberately control the distance between the car roofs. When the roof is placed on the outside of the drying flat net, there will be more empty spaces on the drying flat net, which will affect the drying efficiency. After the drying is completed, the drying flat net can be driven to rotate to make the car roof fall onto the conveyor belt. As the conveyor belt moves, the dried car roof is transmitted out, which is convenient for taking the car roof. However, when this method is used, if a large number of car roofs fall, the car roofs will collide with each other during the falling process, which may easily cause damage to the car roof. In addition, the car roofs may be stacked after falling. In some cases, the dried car roofs need to be placed on the conveyor belt one by one to enter the next process for processing. When multiple car roofs are stacked, they need to be separated manually, which is more troublesome.

[0006] To this end, the present invention provides a convection drying device for producing automobile roofs. Summary of the invention

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The convection drying equipment for producing automobile roofs described in the present invention utilizes a clamping displacement mechanism. Workers only need to place the automobile roof to be dried on the edge of the turntable, and the rear end of the clamping plate clamps the automobile roof to drive the clamped automobile roof to move toward the axis of the turntable. The subsequent automobile roof can be close to the previous automobile roof, so that multiple automobile roofs are radially distributed on the turntable and placed in multiple rows. In addition, the distance between the automobile roofs is minimized to the greatest extent without the automobile roofs touching each other. While fully utilizing the placement space of the turntable, the drying effect will not be affected by the automobile roofs covering each other, thereby improving the drying efficiency. At the same time, the process of manually placing the automobile roof on the turntable is omitted, which saves manpower. Moreover, after the drying is completed, the rear automobile roof can push the front automobile roof, so that the multiple automobile roofs can slide onto the blanking plate one by one, and the end of the blanking plate can be aligned with the conveyor belt used to allow the automobile roof to enter the next process. At this time, the multiple automobile roofs can be arranged in an arranged manner and enter the next process via the conveyor belt. The process realizes the automatic unloading of the car roof from the turntable, and also avoids the situation that the car roof is damaged due to direct dumping of the car roof, and the car roof will not be stacked due to dumping, and it needs to be manually separated before multiple car roofs can enter the next process one by one. At the same time, because the clamping plate has a certain length, when the spacer pushes the car roof to move, the car roof will only move between the two clamping plates, and the car roof will not deviate from the pushing trajectory, which further ensures the normal unloading of the car roof. In addition, when the spacer pushes the car roof to move, it drives multiple transmission blocks to slide on the sliding rod four at the same time and change equidistantly, so that each spacer can just align with the gap between the two adjacent car roofs, and through the movement of the transmission rod, each spacer is inserted into the gap between the two adjacent car roofs. When multiple spacers push the car roof at the same time, the rear car roof will not cover the front car roof under the blocking effect of the spacer, which further ensures that the car roof enters the next process one by one in an arranged manner.

[0021] 2. The convection drying equipment for producing automobile roofs described in the present invention can drive the fixing plate to rotate to a state parallel to the turntable through motor six during the drying process, and then use electric push rod three to drive the fixing plate to descend to press multiple automobile roofs, thereby ensuring the stability of the automobile roof during the drying process and preventing it from shifting.

[0022] 3. The convection drying equipment for producing automobile ceilings described in the present invention utilizes hot air blowers on both sides to transport hot air to the inside of a drying box through an air hood, thereby convection drying the automobile ceiling, allowing the hot air to flow evenly inside the drying box, which is beneficial to improving drying efficiency.

[0048] Specifically, when the existing car roof drying equipment is used, the car roof is placed on the drying flat net, and then the car roof is dried by hot air. However, in some cases, in order to improve the drying efficiency, multiple car roofs need to be dried at one time. When multiple car roofs are placed on the drying flat net manually, it is easy for the car roofs to contact and fit each other, resulting in the car roofs covering each other, thereby affecting the drying effect. In addition, in order to dry multiple car roofs at the same time, the placement area of ​​the drying flat net will also be set too large. When the placement area of ​​the drying flat net is large, it is not easy for workers to place the car roof to the area relatively inner of the drying flat net. Therefore, in order to avoid the car roofs covering each other and affecting the drying effect, the distance between the car roofs is deliberately controlled. It is quite laborious, and if the car roof is only placed outside the drying flat net, there will be many vacant positions on the drying flat net, which will affect the drying efficiency. Moreover, after the drying is completed, the drying flat net can be driven to rotate so that the car roof falls onto the conveyor belt. With the movement of the conveyor belt, the dried car roof is transmitted out, which is convenient for taking the car roof. However, when this method is adopted, if a large number of car roofs fall, the car roofs will collide with each other during the falling process, which may easily cause damage to the car roof. Moreover, the car roofs may be stacked after falling. In some cases, the dried car roofs need to be placed on the conveyor belt one by one to enter the next process for processing. When multiple car roofs are stacked, they need to be separated manually, which is quite troublesome.

[0049] Therefore, in order to solve the above problem, for the same batch of car roofs with the same specifications, the worker stands in front of the drying box 1, places the car roof to be dried on the edge of the turntable 2, and then uses the electric push rod 1 7 to drive the mounting plate 9 to descend, so that the car roof is between the two clamping plates 14, and then uses the electric push rod 2 12 to drive the clamping plate 14 on one side to move, and then with the cooperation of the connecting rod 10 and the connecting rod 2 11, the two clamping plates 14 can be moved at the same time and approach each other, and the car roof is clamped by the rear end of the clamping plate 14, and then the motor 3 27 is used to drive the threaded rod 3 28 to rotate, so that the mounting rod 6 can be moved toward the axial direction of the turntable 2. When the car roof moves to a suitable After the position is reached, the mounting rod 6 stops moving, and then the clamping plate 14 is reset. At this time, the worker can then place the next car roof on the turntable 2, and cooperate with the motor 5 32 to drive the turntable 2 to rotate, so that the subsequent car roof can be close to the previous car roof, so that multiple car roofs are radially distributed on the turntable 2 and placed in multiple rows, and the distance between the car roofs is minimized to the greatest extent without the car roofs touching each other, while fully utilizing the placement space of the turntable 2, there will be no situation where the car roofs cover each other and affect the drying effect, and at the same time, it also saves the process of manually placing the car roof on the turntable 2, which is relatively labor-saving;

[0050] When all the car roofs are placed, close the door, and use the hot air blowers 3 on both sides to transport the hot air to the inside of the drying box 1 through the wind hood 4, so as to perform convection drying on the car roofs;

[0051] After drying, the box door is opened, and then the motor 26 is used to drive the blanking plate 5 to rotate so that one end of the blanking plate 5 is close to the edge of the turntable 2. At this time, the two clamping plates 14 are driven to move again so that a row of car roofs are between the two clamping plates 14, and then the motor 4 29 is started to drive the threaded rod 21 to rotate, so that the threaded block 13 and the transmission rod 20 move. When the transmission rod 20 contacts the pressure plate 24 on the rear side, since one side of the pressure plate 24 is an inclined surface, the pressure plate 24 will move downward due to the squeezing of the transmission rod 20. At this time, the spacer 15 on the rear side will drop due to the squeezing of the transmission rod 20, and when the mounting rod 6 moves forward, the spacer 15 will push the car roof on the rear side, that is, the rear car roof can push the front car roof in a way that multiple car roofs can be moved. The roofs slide down onto the unloading plate 5 one by one, and the end of the unloading plate 5 can be aligned with the conveyor belt used to allow the car roof to enter the next process. At this time, multiple car roofs can be arranged in an array and enter the next process via the conveyor belt, thereby realizing the automatic unloading of the car roof from the turntable 2, and also avoiding the situation that the car roof is damaged by directly dumping the car roof, and there will be no situation that the car roof is stacked due to dumping, and manual separation is required before multiple car roofs can enter the next process one by one. At the same time, since the clamping plate 14 has a certain length, when the spacer 15 pushes the car roof to move, the car roof will only move between the two clamping plates 14, and the car roof will not deviate from the pushing trajectory, further ensuring the normal unloading of the car roof;

[0052] Since the car roof has a certain curvature and its two ends are in a warped state, when the rear car roof pushes the front car roof, the rear car roof may cover the front car roof, which will cause the car roof to overlap, thereby affecting the car roof from smoothly entering the next process. Therefore, in order to avoid this situation, since the spacing between each row of car roofs is the same, the motor 19 can drive the threaded rod 16 to rotate, so that the frontmost transmission block 23 moves, and the transmission block 23 of the connecting rod 3 17 and the connecting rod 4 18 is driven by the motor 19 to rotate. Under the present invention, multiple transmission blocks 23 slide on the sliding rod 436 at the same time and change equidistantly, so that each spacer 15 can be just aligned with the gap between two adjacent car roofs, and each spacer 15 is inserted into the gap between two adjacent car roofs through the movement of the transmission rod 20. When multiple spacers 15 push the car roof at the same time, the rear car roof will not cover the front car roof due to the blocking effect of the spacers 15, thereby further ensuring that the car roofs enter the next process one by one in an arranged manner.

[0053] In this embodiment, Figure 2 , Figure 7 , Figure 8As shown, two slide bars 31 are slidably connected to one side of the bottom of the drying box 1, the upper ends of the slide bars 31 are fixedly connected to a frame 35, both ends of the frame 35 are rotatably provided with fixed plates 33, one end of the frame 35 is fixedly connected to a motor 6 34, the output end of the motor 6 34 is fixedly connected to one end of the fixed plate 33, one side of the lower end surface of the drying box 1 is fixedly connected to an electric push rod 30, and the piston end of the electric push rod 30 is fixedly connected to one side of the bottom of the frame 35.

[0054] Specifically, during the drying process, the motor 6 34 can drive the fixing plate 33 to rotate to a state parallel to the turntable 2, and then the electric push rod 3 30 can be used to drive the fixing plate 33 to descend, thereby pressing multiple car roofs together, thereby ensuring the stability of the car roof during the drying process and preventing it from shifting.

[0055] Working principle: the worker stands in front of the drying box 1, places the car roof to be dried on the edge of the turntable 2, and then uses the electric push rod 1 7 to drive the installation plate 9 to descend, so that the car roof is between the two clamping plates 14, and then uses the electric push rod 2 12 to drive the clamping plate 14 on one side to move, and under the cooperation of the connecting rod 10 and the connecting rod 2 11, the two clamping plates 14 can be moved at the same time and approach each other, and the car roof is clamped by the rear end of the clamping plate 14, and then the motor 3 27 is used to drive the threaded rod 3 28 to rotate, so that the installation rod 6 can be moved toward the axial direction of the turntable 2. When the car roof moves to the appropriate position, the installation rod 6 stops moving, and then the clamping plate 14 is reset. At this time, the worker can then place the next car roof on the turntable 2, and, with the cooperation of the motor 5 32 to drive the rotation of the turntable 2, the subsequent car roof can be moved closer to the previous car roof. Multiple car roofs are radially distributed on the turntable 2 and placed in multiple rows. When the car roofs do not touch each other, the distance between the car roofs is minimized to the greatest extent. While fully utilizing the placement space of the turntable 2, the drying effect will not be affected by the car roofs covering each other. At the same time, the process of manually placing the car roofs on the turntable 2 is omitted, which saves manpower. When all the car roofs are placed, the box door is closed, and the hot air is transported to the inside of the drying box 1 through the wind hood 4 by the hot air blowers 3 on both sides, so that the car roofs can be convection dried. During the drying process, the motor 6 34 can drive the fixing plate 33 to rotate to a state parallel to the turntable 2, and then the electric push rod 3 30 is used to drive the fixing plate 33 to descend, so that multiple car roofs are pressed tightly, thereby ensuring the stability of the car roof during the drying process and preventing it from deflecting.After drying, the box door is opened, and then the motor 26 is used to drive the blanking plate 5 to rotate, so that one end of the blanking plate 5 is close to the edge of the turntable 2. At this time, the two clamping plates 14 are driven to move again, so that a row of car roofs are between the two clamping plates 14, and then the motor 4 29 is started to drive the threaded rod 21 to rotate, so that the threaded block 13 and the transmission rod 20 move. When the transmission rod 20 contacts the pressure plate 24 on the rear side, since one side of the pressure plate 24 is an inclined surface, the pressure plate 24 will move downward due to the squeezing of the transmission rod 20. At this time, the spacer 15 on the rear side will drop due to the squeezing of the transmission rod 20, and when the mounting rod 6 moves forward, the spacer 15 The rearmost car roof can be pushed, that is, the rear car roof can push the front car roof, so that multiple car roofs can slide onto the unloading plate 5 one by one, and the end of the unloading plate 5 can be aligned with the conveyor belt used to make the car roof enter the next process. At this time, multiple car roofs can be arranged in an array and enter the next process through the conveyor belt, thereby realizing the automatic unloading of the car roof from the turntable 2, and avoiding the situation that the car roof is damaged by directly dumping the car roof, and the car roof will not be stacked due to dumping, and manual separation is required before multiple car roofs can enter the next process one by one. At the same time, due to the clamping plate 14 has a certain length, so when the spacer 15 pushes the car roof to move, the car roof will only move between the two clamping plates 14, and the car roof will not deviate from the pushing trajectory, further ensuring the normal unloading of the car roof; and because the car roof has a certain curvature, its two ends are in a warped state, when the rear car roof pushes the front car roof, the rear car roof may cover the front car roof, which will cause the car roof to overlap, thereby affecting the car roof from entering the next process smoothly. Therefore, in order to avoid this situation, since the spacing between each row of car roofs is the same, the motor 19 can be used to The threaded rod 16 is driven to rotate, so that the transmission block 23 at the front side moves, and under the transmission of the connecting rod 3 17 and the connecting rod 4 18, multiple transmission blocks 23 slide on the sliding rod 4 36 at the same time, and change equidistantly, so that each spacer 15 can just align with the gap between two adjacent car roofs, and through the movement of the transmission rod 20, each spacer 15 is inserted into the gap between two adjacent car roofs. When multiple spacers 15 push the car roof at the same time, the rear car roof will not cover the front car roof under the blocking effect of the spacers 15, thereby further ensuring that the car roofs enter the next process one by one in an arranged manner. ;
