Description
Technical Field
[0001] The utility model relates to the technical field of automatic turnover devices, in particular to an automatic turnover device. Background Art
[0002] The turnover device is a device widely used in industries such as industrial production, logistics, food processing, agriculture, and warehousing, mainly used to realize the turnover of objects for the purposes of handling, processing, packaging, displaying, or cleaning. During the production process of foods such as cakes and breads, it is necessary to take out the cakes from the baking trays and transfer them to the conveyor belts of the next process.
[0003] During the process of turning over the baking trays, the staff often find that: currently, it is usually the staff who lift the baking trays and pour the cakes in the baking trays onto the conveyor belts of the next process. Since the temperature of the cake baking trays is relatively high and they have a certain weight during turnover, it is easy to cause the staff to be scalded by the baking trays during turnover. Content of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an automatic turnover device.
[0005] To achieve the above purpose, the utility model adopts the following technical solution: an automatic turnover device includes four columns. A conveyor table is fixedly connected to the four columns. Two rotating shafts are rotatably connected to the columns. Two belt pulleys are fixedly connected to the rotating shafts. A transmission belt is arranged on the two belt pulleys. A second motor is fixedly connected to the conveyor table. The output shaft of the second motor is fixedly connected to one of the rotating shafts. A turnover structure is arranged on the conveyor table. The turnover structure mainly consists of a rotating shaft. The rotating shaft is rotatably connected to the conveyor table. A third motor is fixedly connected to the conveyor table. The output shaft of the third motor is fixedly connected to the rotating shaft. A turnover plate is fixedly connected to the rotating shaft. A first cylinder is fixedly connected to the turnover plate. A clamping block is fixedly connected to the piston rod of the first cylinder.
[0006] The effects achieved by the above components are as follows: When the second motor is started, the output shaft of the second motor drives a rotating shaft to rotate, which in turn drives two pulleys to rotate. Under the action of the transmission belt, the four pulleys rotate synchronously, enabling the two transmission belts to convey the baking tray to a specified position. The third motor is a servo motor, and its rotation angle can be controlled by an encoder. When the third motor is started, the output shaft of the third motor drives the rotating shaft to rotate above the transfer table. At the same time, two first cylinders are started to drive the two clamping blocks to approach each other to clamp the baking tray. Then the third motor is started again to drive the rotating shaft to rotate 180 degrees, causing the cake to fall onto the conveyor belt in the next process on one side of the transfer table, thus avoiding the situation where the staff is easily scalded by the baking tray during the turnover process because the baking tray of the cake is at a relatively high temperature and has a certain weight during the turnover process.
[0007] Preferably, two round rods are fixedly connected to the clamping block, and the round rods are slidably inserted into the turnover plate.
[0008] The effects achieved by the above components are as follows: The two round rods limit the clamping block, making the movement process of the clamping block more stable.
[0009] Preferably, a second cylinder is fixedly connected to the column, and a top plate is fixedly connected to the piston rod of the second cylinder.
[0010] The effects achieved by the above components are as follows: When the second cylinder is started, the second cylinder drives the top plate to rise, which in turn drives the baking tray to rise, enabling the lower end of the clamping block to support the baking tray.
[0011] Preferably, a rubber pad is fixedly connected to the clamping block.
[0012] The effects achieved by the above components are as follows: The rubber pad can increase the friction with the baking tray, thereby further improving the limiting effect.
[0013] Preferably, a limiting structure is provided on the turnover plate. The limiting structure mainly consists of four electric telescopic rods, and a cover plate is fixedly connected to the four electric telescopic rods together.
[0014] The effects achieved by the above components are as follows: After clamping, starting the four electric telescopic rods simultaneously can drive the cover plate to descend to limit the items in the baking tray and prevent them from falling during flipping.
[0015] Preferably, two sliding plates are slidably inserted into the cover plate.
[0016] The effects achieved by the above components are as follows: After the rotating shaft rotates, sliding the two sliding plates away from each other can enable the items to fall out of the baking tray, and then place the baking tray on the two transmission belts to move it away.
[0017] Preferably, a rack is fixedly connected to the sliding plate, and a gear is meshed and connected to the two racks together.
[0018] The effects achieved by the above components are as follows: By rotating the gear, the two racks can be driven to move in opposite directions, and then the sliding plate can be driven to move in the opposite direction to open.
[0019] Preferably, a first motor is fixedly connected to the cover plate, and the output shaft of the first motor is fixedly connected to the gear.
[0020] The effects achieved by the above components are as follows: By starting the first motor, the output shaft of the first motor drives the gear to rotate, making the operation more convenient.
[0021] Compared with the prior art, the advantages and positive effects of the present utility model are that in the present utility model, by setting a turnover structure, the third motor is a servo motor, and the rotation angle can be controlled by an encoder. By starting the third motor, the output shaft of the third motor drives the rotating shaft to rotate above the conveyor table. At the same time, two first cylinders are started to drive the two clamping blocks to approach each other to clamp the baking tray. Then, the third motor is started to drive the rotating shaft to rotate 180 degrees, so that the cake falls onto the conveyor belt in the next process located on one side of the conveyor table, thus avoiding the situation that the staff is easily scalded by the baking tray during the turnover process because the cake baking tray has a high temperature and a certain weight during the turnover.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] Example 1, as shown in Figure 1 and Figure 4 An automatic turnover device includes four columns 1. A transfer table 2 is fixedly connected to the four columns 1 together. Two rotating shafts 5 are rotatably connected to the columns 1. Two belt pulleys 6 are fixedly connected to the rotating shafts 5. A transmission belt 7 is arranged on the two belt pulleys 6 together. A second motor 8 is fixedly connected to the transfer table 2. The output shaft of the second motor 8 is fixedly connected to one of the rotating shafts 5.
[0028] Referring to Figure 1 and Figure 2 A turnover structure 3 is arranged on the transfer table 2. The turnover structure 3 mainly consists of a rotating shaft 31. The rotating shaft 31 is rotatably connected to the transfer table 2. A third motor 39 is fixedly connected to the transfer table 2. The output shaft of the third motor 39 is fixedly connected to the rotating shaft 31. A turnover plate 32 is fixedly connected to the rotating shaft 31. A first cylinder 34 is fixedly connected to the turnover plate 32. A clamping block 33 is fixedly connected to the piston rod of the first cylinder 34. When the second motor 8 is started, the output shaft of the second motor 8 drives one of the rotating shafts 5 to rotate, and then drives the two belt pulleys 6 to rotate. Under the action of the transmission belt 7, the four belt pulleys 6 rotate synchronously, so that the two transmission belts 7 convey the baking tray to a specified position. The third motor 39 is a servo motor, and the rotation angle can be controlled by an encoder. When the third motor 39 is started, the output shaft of the third motor 39 drives the rotating shaft 31 to rotate above the transfer table 2. At the same time, two first cylinders 34 are started to drive the two clamping blocks 33 to approach each other to clamp the baking tray. Then the third motor 39 is started to drive the rotating shaft 31 to rotate 180 degrees, so that the cake falls onto the conveyor belt in the next process on one side of the transfer table 2, thus avoiding the situation that the staff is easily scalded by the baking tray during turnover because the temperature of the cake baking tray is relatively high and it has a certain weight. Two round rods 35 are fixedly connected to the clamping block 33. The round rods 35 are slidably inserted into the turnover plate 32. The two round rods 35 limit the clamping block 33, making the movement process of the clamping block 33 more stable. A second cylinder 36 is fixedly connected to the column 1. A top plate 37 is fixedly connected to the piston rod of the second cylinder 36. When the second cylinder 36 is started, the second cylinder 36 drives the top plate 37 to rise, and then drives the baking tray to rise, so that the lower end of the clamping block 33 can support the baking tray. A rubber pad 38 is fixedly connected to the clamping block 33. The rubber pad 38 can increase the friction with the baking tray, thereby further improving the limiting effect.
[0029] Referring to Figure 1 and Figure 3, a limiting structure 4 is provided on the turnover plate 32. The limiting structure 4 mainly consists of four electric telescopic rods 41. A cover plate 42 is fixedly connected to the four electric telescopic rods 41 together. After the clamping is completed, starting the four electric telescopic rods 41 simultaneously can drive the cover plate 42 to descend, limit the items in the baking tray, and prevent them from falling during flipping. Two sliding plates 43 are slidably inserted into the cover plate 42. After the rotating shaft 31 rotates, sliding the two sliding plates 43 away from each other can make the items fall out of the baking tray. Then, place the baking tray on the two transmission belts 7 to move it away. A rack 44 is fixedly connected to the sliding plate 43. A gear 45 is meshed with the two racks 44 together. Rotating the gear 45 can drive the two racks 44 to move in the opposite direction, and then drive the sliding plates 43 to move in the opposite direction to open. The cover plate 42 is fixedly connected to a first motor 46. The output shaft of the first motor 46 is fixedly connected to the gear 45. Starting the first motor 46, the output shaft of the first motor 46 drives the gear 45 to rotate, making the operation more convenient.
[0030] Working principle: Start the second motor 8. The output shaft of the second motor 8 drives a rotating shaft 5 to rotate, and then can drive two belt pulleys 6 to rotate. Under the action of the transmission belt 7, the four belt pulleys 6 rotate synchronously, so that the two transmission belts 7 convey the baking tray to a specified position. The third motor 39 is a servo motor and can control the rotation angle through an encoder. Start the third motor 39. The output shaft of the third motor 39 drives the rotating shaft 31 to rotate above the transfer table 2. At the same time, start the two first cylinders 34 to drive the two clamping blocks 33 to approach each other and clamp the baking tray. Then start the third motor 39 to drive the rotating shaft 31 to rotate 180 degrees, so that the cake falls onto the conveyor belt in the next process on one side of the transfer table 2, thus avoiding the situation that the staff is easily scalded by the baking tray during the turnover because the baking tray of the cake is at a high temperature and has a certain weight during the turnover process. The two round rods 35 limit the clamping blocks 33, making the movement process of the clamping blocks 33 more stable. Start the second cylinder 36. The second cylinder 36 drives the top plate 37 to rise, and then drives the baking tray to rise, so that the lower end of the clamping block 33 can support the baking tray. The rubber pad 38 can increase the friction with the baking tray, thereby further improving the limiting effect. After the clamping is completed, starting the four electric telescopic rods 41 simultaneously can drive the cover plate 42 to descend, limit the items in the baking tray, and prevent them from falling during flipping. After the rotating shaft 31 rotates, sliding the two sliding plates 43 away from each other can make the items fall out of the baking tray. Then, place the baking tray on the two transmission belts 7 to move it away. Rotating the gear 45 can drive the two racks 44 to move in the opposite direction, and then drive the sliding plates 43 to move in the opposite direction to open. Start the first motor 46. The output shaft of the first motor 46 drives the gear 45 to rotate, making the operation more convenient.
