[0026] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0028] See also Figures 1-6 As shown, the utility model is a continuous stacking and collecting device for flaky food, comprising a support assembly 1, a conveying device 2 is fixedly installed on the top of the support assembly 1, a transmission assembly 6 is rotatably installed on the bottom of the inner cavity of the support assembly 1, an adjustment assembly 3 is rotatably installed on the top of the inner cavity of the support assembly 1, an electric push rod 4 is fixedly installed on the bottom of the adjustment assembly 3, an adsorption assembly 5 is fixedly installed on the bottom end of the electric push rod 4, an infrared sensor 7 and an identifier 9 are fixedly installed in the inner cavity of the support assembly 1, and a conveyor belt assembly 8 is fixedly installed in the inner cavity of the support assembly 1.

[0029] When it is necessary to use this device to stack and collect sheet foods, first, the device can be installed in the use position with the help of the support component 1. In order to facilitate the adjustment of the limit frame on the conveyor belt, the limit frame can be adjusted according to the size of the sheet foods. The inner part of the conveyor belt component 8 can be manually pulled to make the inner part slide and drive the limit frame to move. The two limit frames are moved to a suitable width position to convey the sheet foods. Subsequently, the produced sheet foods are conveyed to the conveyor belt component 8 through the conveying device 2. In order to facilitate the stacking and collection of sheet foods, when the sheet foods pass through the inner part of the support component 1, the inner part of the transmission component 6 and the infrared sensor 7 can be controlled by the controller to work. The infrared sensor 7 works to sense and measure the sheet foods introduced into the inner part of the support component 1. When the sheet foods in the inner part of the support component 1 reach a certain amount, the inner parts are driven to rotate through the inner part of the transmission component 6. The components are rotated by belt transmission, so that the rotation of the inner component drives the blocking frame to rotate, so that the blocking frame blocks and stacks the sheet food, thereby facilitating the stacking of the sheet food. In this process, the controller controls the identification device 9 and the inner components of the adjustment component 3 to work, and the operation of the inner components of the adjustment component 3 drives the rotation of the inner components of the adjustment component 3. Due to the threaded installation between the inner components, the rotation of the inner components of the adjustment component 3 drives the adsorption component 5 to move, and then the controller controls the inner components of the adsorption component 5 to work. After the identification sensing of the identifier 9, the damaged sheet food in the conveyor belt is identified and picked up, and then the controller controls the electric push rod 4 to work. The electric push rod 4 drives the inner components of the adsorption component 5 to move, move it to a suitable height position to adsorb and pick up the damaged sheet food, and then use the adsorption device to pick the damaged sheet food into the inner components of the supporting component 1, thereby facilitating the picking of the damaged sheet food, thereby achieving the purpose of saving time and effort.

[0030] The controller controls the operation of the internal components of the transmission assembly 6 and the infrared sensor 7. The infrared sensor 7 senses and measures the flaky food introduced into the internal components of the support assembly 1. When the flaky food in the internal components of the support assembly 1 reaches a certain amount, the internal components of the transmission assembly 6 are driven to rotate. Since the internal components rotate via the belt drive, the rotation of the internal components drives the blocking frame to rotate, so that the blocking frame blocks and stacks the flaky food, thereby facilitating the stacking of the flaky food, thereby saving time and effort.

[0031] Thus, the controller controls the operation of the identifier 9 and the internal components of the adjustment component 3, and the operation of the internal components of the adjustment component 3 drives the internal components of the adjustment component 3 to rotate. Due to the threaded installation between the internal components, the rotation of the internal components of the adjustment component 3 drives the adsorption component 5 to move. Then, the controller controls the operation of the internal components of the adsorption component 5. After the identification and sensing of the identifier 9, the damaged flaky food in the conveyor belt is identified and picked up. Then, the controller controls the operation of the electric push rod 4, and the electric push rod 4 drives the internal components of the adsorption component 5 to move, move it to a suitable height position to adsorb and pick up the damaged flaky food, and then use the operation of the adsorption device to pick up the damaged flaky food into the internal components of the support component 1, so as to facilitate the picking of the damaged flaky food, thereby achieving the purpose of saving time and effort.

[0032] In one embodiment, for the above-mentioned support assembly 1, the support assembly 1 includes a support frame 101, a conveying frame 103 is fixedly installed on the top of the support frame 101, a fixed box 102 is fixedly installed on the top of the conveying frame 103, a connecting pipe 105 is fixedly installed in the fixed box 102, and a material receiving box 104 is fixedly installed on one side of the fixed box 102, and the material receiving box 104 is located below the connecting pipe 105.

[0033] The support frame 101 is mainly used to fix and support the device.

[0034] In one embodiment, for the above-mentioned adjustment component 3, the adjustment component 3 includes a threaded rod 302 and a first motor 301, the threaded rod 302 is rotatably installed in the inner cavity of the fixed box 102, the first motor 301 is fixedly installed on one side of the fixed box 102, the output shaft of the first motor 301 is fixedly installed on the threaded rod 302, a threaded block 303 is threadedly installed on the surface of the threaded rod 302, and a movable plate 304 is fixedly installed on the bottom of the threaded block 303.

[0035] In one embodiment, for the above-mentioned adsorption component 5, the adsorption component 5 includes an adsorption device 503 and an adsorber 501, the adsorber 501 is fixedly installed at the bottom end of the electric push rod 4, the adsorption device 503 is fixedly installed at the bottom of the movable plate 304, and a ventilation pipe 502 is fixedly installed on one side of the adsorption device 503, and one end of the ventilation pipe 502 is fixedly installed on the adsorber 501.

[0036] In order to facilitate the picking of damaged flaky food, when the flaky food is conveyed to the inner part of the supporting assembly 1, it is identified by the identifier 9 and the damaged flaky food is identified. Then, the first motor 301 of the controller is operated, and the first motor 301 drives the threaded rod 302 to rotate. Due to the threaded installation of the threaded rod 302 and the threaded block 303, the threaded rod 302 rotates and drives the threaded block 303, the movable plate 304 and the adsorption device 503 to move, thereby driving the adsorber 501 to move, and identify and locate the damaged flaky food identified by the identifier 9. Then, the controller controls the adsorption device 503 to work, and transmits air pressure to the adsorber 501 through the vent pipe 502, so that the adsorber 501 adsorbs and picks the flaky food until the damaged flaky food is adsorbed into the connecting pipe 105 and slides into the receiving box 104, thereby facilitating the picking of the damaged flaky food, thereby saving time and effort.

[0037] In one embodiment, for the above-mentioned transmission assembly 6, the transmission assembly 6 includes a rotating rod 601 and a second motor 603. The number of the rotating rods 601 is two, and the two rotating rods 601 are both rotatably installed in the inner cavity of the fixed box 102. The surfaces of the two rotating rods 601 are respectively fixedly installed with a driving wheel 604 and a driven wheel 606. A belt 605 is used for transmission of rotation between the driving wheel 604 and the driven wheel 606. The second motor 603 is fixedly installed on one side of the fixed box 102, and the output shaft of the second motor 603 is fixedly installed on one of the rotating rods 601. A plurality of blocking frames 602 are fixedly installed on the surfaces of the two rotating rods 601.

[0038] In one embodiment, for the above-mentioned conveyor belt assembly 8, the conveyor belt assembly 8 includes a conveyor belt device 801, and the conveyor belt device 801 is fixedly installed in the conveyor frame 103. Two T-slots 803 are opened in the conveyor frame 103, and a number of T-blocks 804 are slidably installed in the two T-slots 803. A movable frame 802 is fixedly installed on one side of the T-block 804, and the movable frame 802 is located on the surface of the conveyor belt device 801.

[0039] When the movable rack 802 is adjusted, the limit rack can be adjusted according to the size of the sheet food, and then the movable rack 802 is manually pulled, and the movable rack 802 moves to drive the T-block 804 to slide in the T-slot 803 until the width of the two movable racks 802 is adjusted to a suitable width position to limit the sheet food. Subsequently, the produced sheet food is conveyed to the conveyor belt device 801 through the conveying device 2. In order to facilitate the stacking and collection of the sheet food, when the sheet food passes through the fixed box 102, the second motor 603 and the infrared sensor 7 can be controlled by the controller to work, and the infrared sensor 7 is turned on. The external sensor 7 works to sense and measure the flaky food introduced into the fixed box 102. When the flaky food in the fixed box 102 reaches a certain amount, the second motor 603 is activated to drive the rotating rod 601 and the driving wheel 604 to rotate. Since the driving wheel 604 and the driven wheel 606 are driven by the belt 605, the driving wheel 604 rotates, driving the driven wheel 606 and the other rotating rod 601, and then driving the blocking frame 602 to rotate until the blocking frame 602 is rotated to a position to block the flaky food, so that the flaky food can be stacked and collected continuously, thereby saving time and effort.

[0040] In summary, with the aid of the above-mentioned technical solution of the present invention, the damaged flaky food is identified by being conveyed to the inner part of the support assembly 1 and being identified by the identifier 9. Then, the first motor 301 of the controller is operated, and the first motor 301 drives the threaded rod 302 to rotate. Due to the threaded installation of the threaded rod 302 and the threaded block 303, the threaded rod 302 rotates to drive the threaded block 303, the movable plate 304 and the adsorption device 503 to move, thereby driving the adsorber 501 to move, and the damaged flaky food identified by the identifier 9 is identified and positioned. Then, the controller controls the adsorption device 503 to work, and with the help of the vent pipe 502, the air pressure is transmitted to the adsorber 501, so that the adsorber 501 adsorbs and picks the flaky food until the damaged flaky food is adsorbed to the connecting pipe 1. 05 and slides into the material receiving box 104, which makes it easy to pick out the damaged sheet food, thereby achieving the purpose of saving time and effort. The controller controls the second motor 603 and the infrared sensor 7 to work, and the infrared sensor 7 works to sense and measure the sheet food introduced into the fixed box 102. When the sheet food in the fixed box 102 reaches a certain amount, the second motor 603 is operated to drive the rotating rod 601 and the driving wheel 604 to rotate. Since the driving wheel 604 and the driven wheel 606 are driven by the belt 605, the driving wheel 604 rotates, driving the driven wheel 606 and the other rotating rod 601 to rotate, and then drives the blocking frame 602 to rotate until the blocking frame 602 is rotated to the position for blocking the sheet food, so that the sheet food is continuously stacked and collected, thereby achieving the purpose of saving time and effort.

[0041] Through the above technical solution, the controller controls the operation of the internal parts of the transmission assembly 6 and the infrared sensor 7, and the infrared sensor 7 works to sense and measure the sheet food introduced into the internal parts of the support assembly 1. When the sheet food in the internal parts of the support assembly 1 reaches a certain amount, the internal parts of the transmission assembly 6 are driven to rotate. Since the internal parts rotate through the belt drive, the rotation of the internal parts drives the blocking frame to rotate, so that the blocking frame blocks and stacks the sheet food, thereby facilitating the stacking of the sheet food, thereby achieving the purpose of saving time and effort. The controller controls the operation of the identifier 9 and the internal parts of the adjustment assembly 3, and the working belt of the internal parts of the adjustment assembly 3 The inner parts of the dynamic adjustment component 3 rotate. Due to the threaded installation between the inner parts, the rotation of the inner parts of the adjustment component 3 drives the adsorption component 5 to move. The controller then controls the inner parts of the adsorption component 5 to work. After the identification and sensing of the identifier 9, the damaged sheet food in the conveyor belt is identified and picked up. The controller then controls the electric push rod 4 to work. The electric push rod 4 drives the inner parts of the adsorption component 5 to move, moves it to a suitable height position to adsorb and pick up the damaged sheet food, and then uses the adsorption device to pick up the damaged sheet food into the inner parts of the support component 1, so as to facilitate the picking of the damaged sheet food, thereby achieving the purpose of saving time and effort.
