The cold air groove is connected to the cold air cavity through a shaft, and the opening of the air outlet is inclined downward with respect to the material placement plate.

[0016] The present invention provides a biscuit detection device for reducing detection blind spots, which has the following beneficial effects: when in use, the biscuits do not need to be turned over, and double-sided detection can be performed on them during the transfer process, so as to reduce the detection blind spot and avoid the biscuits from being broken when turned over, and when the biscuits are transferred, moisture detection and weight detection can be performed on them simultaneously, and unqualified products can be directly rejected during the transfer process, thereby completing the detection and sorting of the biscuits.

[0017] 1. When the present invention is in use, biscuits are placed on the feeding belt, and the feeding belt and the unloading belt are started. The feeding belt can intermittently convey the biscuits. The baffle can limit the biscuits to prevent them from falling from the feeding belt. At the same time, the baffle can also guide the biscuits so that they can be arranged in a row on the feeding belt when they reach the side of the feeding belt close to the turntable, which is convenient for their transfer. The partition can further limit the biscuits to prevent them from overlapping when they are arranged, thereby causing multiple biscuits to fall into the placing plate at the same time. When the biscuits move to the end of the feeding belt, After the biscuits are removed from the material tray, they can slide down onto the loading plate under the guidance of the material guide plate, and slide along the inclined surface of the loading plate to the inner side of the loading plate. Because the loading plate is made of transparent material, the bottom image of the biscuits can be presented on the reflector. At this time, the camera shoots through the loading plate, so that the front and back sides of the biscuits can be detected at the same time. There is no need to flip the biscuits to avoid the biscuits from being broken during the flipping detection. In summary, when in use, there is no need to flip the biscuits, and they can be inspected on both sides during the transfer process to reduce the detection blind area and avoid the biscuits from being broken when flipping.

[0018] 2. After the biscuits fall onto the loading plate, the hot air blower can transport hot air into the air guide pipe, so that the hot air enters the hot air cavity from the opening through the air hole and is blown to the biscuits through the two sides of the empty slot. If the biscuits are damp, the moisture in the biscuits will evaporate from the inside of the biscuits under the heating of the hot air and condense into water droplets on the wall of the loading plate. When the camera shoots the appearance of the biscuits, it can synchronously shoot the loading plate. If water droplets are found on the wall of the loading plate, it means that the biscuits are damp and are unqualified. If no water droplets are found, it means that the biscuits are not damp. Then the driving motor drives the driving wheel to rotate, and the driving wheel can drive the turntable to rotate intermittently at an angle of 90° to move the biscuits. When the turntable rotates, the rotating plate can limit the support rod through the rotating groove to avoid the support rod from deflecting and keep the support rod stable. At the same time, the support plate can also The support keeps the turntable stable, and the inclined surface on the loading plate can limit the biscuits to prevent the biscuits from flying out of the loading plate due to centrifugal force. After the rotation is completed, the electromagnet can be powered on and off according to the shooting results of the camera. If the shooting results show that the front and back surfaces of the biscuits are intact, the appearance meets the requirements, and there are no water droplets on the loading plate, it means that the biscuits are qualified in this detection step, and the electromagnet is not energized. Otherwise, the electromagnet is energized to adsorb the loading plate and stretch the reset spring, so that the loading plate rotates and tilts in the empty slot through the shaft rod, and the biscuits can slide out of the loading plate due to the tilt and fall onto the unloading belt to complete the unloading. After the loading plate leaves the top of the electromagnet, the loading plate can rebound and reset under the action of the reset spring. In summary, when performing appearance inspection, the biscuits can be simultaneously tested for moisture, and unqualified biscuits can be unloaded during the transfer process after the inspection is completed.

[0019] 3. In the present invention, after the biscuits are moved to the side away from the feeding belt, the ventilation pipe is connected with the ventilation port, and the cold air blower is started, so that the cold air flow can be sent into the cold air cavity through the ventilation pipe from the ventilation port, and then sent into the cold air slot through the shaft rod, and blown out through the air outlet. At this time, if the weight of the biscuits does not meet the standard, the biscuits will be blown out from the loading plate by the air flow under the blowing of the cold air, and the unloading is completed directly. If the weight of the biscuits meets the standard, the cold air can blow away the biscuit crumbs that may exist on the loading plate and cool the loading plate and the biscuits, so as to avoid the biscuits being tested for moisture again because the loading plate temperature is too high. The high pressure makes it impossible for water vapor to condense on the placing plate, resulting in inaccurate detection. After the turntable moves the biscuits to the front side, the electromagnet is energized to adsorb the placing plate, so that the biscuits slide along the placing plate to the unloading belt on the front side of the turntable, completing the unloading of qualified products. After the turntable rotates again to make the placing plate leave the top of the electromagnet, the placing plate can rebound and reset under the action of the reset spring, which is convenient for receiving the biscuits. In summary, during the transfer process of the biscuits, the biscuits can be cooled and weight-detected, and the screening of unqualified products can be completed simultaneously during the detection, so as to sort the biscuits.

The support plate 14 is fitted with the chassis 1, a vent 20 is provided on the upper surface of the turntable 204, and a cold air cavity 21 is provided on one side of the vent 20, the cold air cavity 21 is C-shaped, and the ventilation pipe 9 is connected with the cold air cavity 21 through the vent 20, a cold air groove 22 is provided on one side of the material placing plate 207, and an air outlet 23 is provided in the middle of the cold air groove 22, the cold air groove 22 is connected with the cold air cavity 21 through the shaft 206, and the opening of the air outlet 23 is inclined downward with respect to the material placing plate 207;

[0031] The specific operation is as follows. After the biscuits fall onto the loading plate 207, the hot air blower 17 can transport hot air into the air guide 16, so that the hot air enters the hot air chamber 19 from the opening 15 through the air vent 18, and blows toward the biscuits through the two sides of the empty slot 205. If the biscuits are damp, the moisture in the biscuits will evaporate from the inside of the biscuits under the heating of the hot air and condense into water droplets on the upper wall of the loading plate 207. When the camera 7 takes pictures of the appearance of the biscuits, it can take pictures of the loading plate 207 synchronously. If water droplets are found on the upper wall of the loading plate 207, it means that the biscuits are damp and are defective. If no water droplets are found, it means that the biscuits are not damp. Then the driving motor 212 drives the driving wheel 211 to rotate, and the driving wheel 210 can be used to make the support rod 203 The turntable 204 is driven to rotate intermittently at an angle of 90° to move the biscuits. When the turntable 204 rotates, the rotating plate 202 can limit the support rod 203 through the rotating groove 201 to prevent the support rod 203 from deflecting and keep the support rod 203 stable.

After the rotation is completed, the electromagnet 10 can be powered on and off according to the shooting results of the camera 7. If the shooting results show that the appearance of the front and back of the biscuits is intact, the appearance meets the requirements, and there are no water drops on the material placement plate 207, it means that the biscuits are qualified in this detection step, and the electromagnet 10 is not turned on. The biscuits are then pulled out of the unloading belt 5 and the biscuits are then pulled out of the unloading belt 5. 21, and then sent into the cold air slot 22 through the shaft 206, and blown out through the air outlet 23. At this time, if the weight of the biscuits does not meet the standard, the biscuits will be blown out from the loading plate 207 by the air flow under the blowing of the cold wind, and the unloading is completed directly. If the weight of the biscuits meets the standard, the cold wind can blow away the biscuit crumbs that may exist on the loading plate 207 and cool the loading plate 207 and the biscuits, so as to avoid the biscuits being tested for moisture again because the temperature of the loading plate 207 is too high and the water vapor cannot condense on the loading plate 207, resulting in inaccurate detection. After the turntable 204 moves the biscuits to the front side, the electromagnet 10 is energized to adsorb the loading plate 207, so that the biscuits slide along the loading plate 207 to the unloading belt 5 on the front side of the turntable 204, and the unloading of qualified products is completed.After the turntable 204 rotates again to make the material placing plate 207 leave the electromagnet 10, the material placing plate 207 can rebound and reset under the action of the reset spring 209, so as to facilitate receiving the biscuits. In summary, during the transfer process of the biscuits, the biscuits can be cooled and weight tested, and unqualified products can be screened synchronously during the testing, so as to sort the biscuits.

[0032] In summary, when using the biscuit detection device that reduces the detection blind spot, first place the biscuits on the feeding belt 4, and start the feeding belt 4 and the unloading belt 5, the feeding belt 4 can then intermittently convey the biscuits, the baffle 12 can limit the biscuits to prevent the biscuits from falling from the feeding belt 4, and at the same time, the baffle 12 can also guide the biscuits so that when they reach the side of the feeding belt 4 close to the turntable 204, they can be arranged in a row on the feeding belt 4 to facilitate their transfer, and the partition 13 can further limit the biscuits to prevent the biscuits from overlapping when they are arranged, thereby causing multiple biscuits to fall into the loading plate 207 at the same time. After moving to the end of the feeding belt 4, the biscuits can slide down to the loading plate 207 under the guidance of the guide plate 11, and slide along the loading plate 20 The inclined surface of 7 slides to the inner side of the loading plate 207. Because the loading plate 207 is made of transparent material, the bottom surface of the biscuit can be reflected on the reflector 3. At this time, the camera 7 shoots through the loading plate 207, so that the front and back sides of the biscuit can be detected at the same time, and there is no need to turn the biscuit over to avoid the biscuit from breaking during the turning detection. After the biscuit falls on the loading plate 207, the hot air blower 17 can transport hot air into the air guide 16, so that the hot air enters the hot air cavity 19 from the opening 15 through the air vent 18, and blows to the biscuit through the two sides of the empty slot 205. If the biscuit is damp, the moisture in the biscuit will evaporate from the inside of the biscuit under the heating of the hot air and condense into water droplets on the upper wall of the loading plate 207. The camera 7 shoots When checking the appearance of the biscuits, the placing plate 207 can be photographed synchronously. If water drops are found on the upper wall of the placing plate 207, it means that the biscuits are damp and are defective. If no water drops are found, it means that the biscuits are not damp. Then the driving motor 212 drives the driving wheel 211 to rotate, and the transmission wheel 210 can be used to make the support rod 203 drive the turntable 204 to rotate intermittently at an angle of 90° to move the biscuits. When the turntable 204 rotates, the rotating plate 202 can limit the support rod 203 through the rotating groove 201 to prevent the support rod 203 from deflecting and keep the support rod 203 stable. At the same time, the support plate 14 can also support the turntable 204 to keep the turntable 204 stable, and the inclined surface on the placing plate 207 can limit the biscuits to prevent the biscuits from being moved away from the rotating plate. The centrifugal force flies out of the material placing plate 207. After the rotation is completed, the electromagnet 10 on the rear side of the turntable 204 can be powered on and off according to the shooting results of the camera 7. If the shooting results show that the front and back surfaces of the biscuits are intact, the appearance meets the requirements, and there are no water drops on the material placing plate 207, it means that the biscuits are qualified in this detection step, and the electromagnet 10 is not energized. Otherwise, the electromagnet 10 is energized to adsorb the material placing plate 207 and stretch the reset spring 209, so that the material placing plate 207 rotates and tilts in the empty slot 205 through the shaft 206. The biscuits can slide out of the material placing plate 207 due to the tilt and fall onto the unloading belt 5 to complete the unloading. After the material placing plate 207 leaves the top of the electromagnet 10, the material placing plate 207 can rebound and reset under the action of the reset spring 209.After the biscuits move to the side away from the feeding belt 4, the ventilation pipe 9 is connected with the ventilation port 20, and the cooling fan 8 is started, and the cold air flow can be sent into the cold air chamber 21 through the ventilation pipe 9 from the ventilation port 20, and then sent into the cold air slot 22 through the shaft 206, and blown out through the air outlet 23. At this time, if the weight of the biscuits does not meet the standard, the biscuits will be blown out from the loading plate 207 by the air flow under the blowing of the cold air, and the unloading is completed directly. If the weight of the biscuits meets the standard, the cold air can blow away the biscuit crumbs that may exist on the loading plate 207 and cool the loading plate 207 and the biscuits, avoiding When the biscuits are tested for moisture again, the water vapor cannot condense on the material plate 207 because the temperature of the material plate 207 is too high, resulting in inaccurate detection. After the turntable 204 moves the biscuits to the front side, the electromagnet 10 is energized to adsorb the material plate 207, so that the biscuits slide along the material plate 207 to the unloading belt 5 on the front side of the turntable 204, completing the unloading of qualified products. After the turntable 204 rotates again to make the material plate 207 leave the electromagnet 10, the material plate 207 can rebound and reset under the action of the reset spring 209, so as to facilitate the acceptance of the biscuits.
