Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food processing, in particular to a semi-automatic tray turnover machine for food electronic accelerator irradiation. BACKGROUND

[0002] With the development of society, the automation and refinement of the food processing industry continue to improve, and the production scale of various types of leisure food such as chicken feet continues to expand. Chicken feet, as a snack that is deeply loved by consumers, need to go through multiple processes during processing. Irradiation is a key link to ensure food safety and extend the shelf life of chicken feet. In the irradiation process of chicken feet, in order to ensure uniform irradiation and completely kill microorganisms and parasites, the bagged chicken feet are usually placed neatly in a tray, and irradiation is performed by the rays generated by an electronic accelerator. In order to ensure that each surface of the chicken feet can fully receive irradiation, the tray containing the chicken feet often needs to be turned over so that the originally downward-facing surface faces upward to achieve full irradiation. Therefore, auxiliary equipment related to irradiation is needed to complete the turnover of the tray. At present, the traditional operation method is to place bagged chicken feet in a tray, then manually buckle a tray on the tray, then manually turn over the two trays, and finally take away the top tray. This operation method has many problems. First, manual turnover of the tray is extremely labor-intensive. The operator needs to frequently repeat actions such as bending over, lifting hands, and turning over, which can easily lead to occupational injuries such as lumbar strain and arm pain after long-term work, which is not conducive to the health of the operator. Second, the efficiency of manual operation is low. Each turnover of a group of trays takes a certain amount of time, which makes it difficult to meet the needs of large-scale production and seriously hinders the overall progress of the production line. Third, the force and angle of manual turnover are difficult to maintain consistent, which affects the integrity of the product and the uniformity of subsequent irradiation. In addition, the contact between personnel and products during manual operation increases the risk of food contamination, which does not meet the hygiene standards of food processing. SUMMARY

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0016] like Figures 1-13 As shown, this embodiment of the invention provides a semi-automatic tray flipping machine for food electron accelerator irradiation, including an input production line 1 and an output production line 2. A tray 6 is placed on top of the input production line 1 and the output production line 2. The tray 6 is used to carry bagged chicken feet for irradiation treatment and subsequent flipping operations. A flipping mechanism 3 is installed between the input production line 1 and the output production line 2. The flipping mechanism 3 is used to flip the stacked trays 6, so that the positions of the upper and lower trays 6 are interchanged. A drive mechanism 4 is installed between the input production line 1 and the flipping mechanism 3. The drive mechanism 4 provides power for the operation of the input production line 1 and the flipping of the flipping mechanism 3. A transfer component 5 is installed between the input production line 1 and the output production line 2. The transfer component 5 is used to transfer the separated trays 6 on the output production line 2 to the input production line 1, realizing the recycling of the trays 6. Input production line 1 includes a support frame 101, a drive roller 102, a driven roller 103, a support roller 104, and a conveyor belt 105. The support frame 101 supports all components of the input production line 1, ensuring its stable installation. The drive roller 102 is movably mounted on the top of the support frame 101. The drive roller 102 rotates under power, providing driving force for the operation of the conveyor belt 105. Two driven rollers 103 and a support roller 104 are movably mounted on the top of the support frame 101. The driven rollers 103 and the support roller 104 support the conveyor belt 105, keeping it taut and ensuring smooth transport. The drive roller 102 is lower than the height of the driven rollers 103. The height difference causes the conveyor belt 105 to form a certain tilt angle, which facilitates the transition of the pallet 6 from the horizontal conveying section to the inclined section under the action of gravity. The outer wall of the drive roller 102 and the two driven rollers 103 is fitted with the conveyor belt 105. The conveyor belt 105 rotates in a cycle under the drive roller 102, thereby driving the pallet 6 placed on it to be conveyed forward. The transmission end of the conveyor belt 105 bends downward. The support roller 104 is located at the bottom of the bend of the conveyor belt 105. The support roller 104 supports the bend of the conveyor belt 105 and prevents the conveyor belt 105 from sagging excessively due to its own weight and the pressure of the pallet 6, ensuring that the pallet 6 can be smoothly conveyed from the conveyor belt 105 to the flipping mechanism 3. Output production line 2 includes a second support frame 201, a second drive roller 202, a second driven roller 203, a second conveyor belt 204, a second side baffle 205, and an inclined plate 206. The second support frame 201 provides support for all components of the output production line 2, ensuring the structural stability of the output production line 2. The second drive roller 202 and the second driven roller 203 are movably mounted on the top of the second support frame 201. The second drive roller 202 rotates under power, driving the second conveyor belt 204 to run. The second driven roller 203 assists in supporting the second conveyor belt 204, keeping the second conveyor belt 204 taut and stable. The outer walls of the second drive roller 202 and the second driven roller 203 are fitted together. A second conveyor belt 204 is provided, which is used to transport the flipped and separated pallet 6 and the carrying chicken feet to the next process. The top of the support frame 201 is fixedly connected to two side baffles 205, which are located on both sides of the second conveyor belt 204. The side baffles 205 can limit the pallet 6 on the second conveyor belt 204 to prevent the pallet 6 from slipping off the sides during the transport process. The front ends of the two side baffles 205 are fixedly connected to inclined plates 206, which facilitate the flipped pallet 6 to slide off the flipping mechanism 3 onto the second conveyor belt 204 of the output production line 2, thus playing a transition role. The flipping mechanism 3 includes a support frame 301, a support plate 302, a horizontal baffle 303, slots 304, a roller 305, and a support shaft 306. The support frame 301 supports the entire flipping mechanism 3, enabling it to be stably installed in a designated position. Two support plates 302 are movably mounted on the top of the support frame 301. The support plates 302 are the main actuators for the flipping action, used to support the pallet 6 and drive it to flip. A horizontal baffle 303 is fixedly connected between the two support plates 302. The horizontal baffle 303 can block the pallet 6 placed on the support plate 302, preventing the pallet 6 from sliding off the rear end of the support plate 302 before flipping. Two slots 304 are provided on the opposite surfaces of the two support plates 302. The slots 304 are used to accommodate the edge of the pallet 6, positioning the pallet 6 and ensuring its stability during flipping. The two slots 304 are located on both sides of the horizontal baffle 303 and can each accommodate a set of stacked pallets 6, improving flipping efficiency. An entry slot is provided on one side of the slot 304, which facilitates the smooth entry of the pallet 6 from the input production line 1 into the slot 304. The entry slots of the two slots 304 are opened in opposite directions, so that the two slots 304 can receive and send out the pallet 6 in different flipping states, realizing continuous operation. Two sets of rollers 305 are movably installed inside the slot 304. The rollers 305 can reduce the friction between the pallet 6 and the inner wall of the slot 304 when the pallet 6 enters or slides out of the slot 304, making the movement of the pallet 6 smoother. The outer ring of the pallet 6 is located between the two sets of rollers 305. Through the rolling action of the rollers 305, the stability of the pallet 6 in the slot 304 is further ensured. A support shaft 306 is fixedly connected to the outer wall of the support plate 302. The support shaft 306 is the axis of rotation of the support plate 302. The support shaft 306 is movably installed inside the support frame 301, so that the support plate 302 can rotate freely around the support shaft 306 on the support frame 301 to realize the flipping action. The drive mechanism 4 includes a support frame 401, a drive motor 402, a drive gear 403, a driven gear 404, a pulley 405, a pulley 406, a drive belt 407, an incomplete gear 408, and a transmission gear 409. The support frame 401 is used to mount the various components of the drive mechanism 4, ensuring they maintain the correct relative positions and that power can be effectively transmitted. The drive motor 402 is fixedly mounted on the top of the support frame 401, serving as the power source for the drive mechanism 4. Drive gears 403 are fixedly connected to both ends of the outer wall of the drive roller 102, and the drive gears 403 rotate together with the drive roller 102, transmitting power to the driven gear 404. The output end of drive motor 402 is fixedly connected to drive roller 102 on one side, enabling drive motor 402 to directly drive drive roller 102 to rotate, thereby driving conveyor belt 105 to operate. A driven gear 404 is movably mounted on the top of support frame 401. The driven gear 404 is used for speed reduction, converting the rapid rotation of drive gear 403 into its own slow rotation. The radius and number of tooth grooves of the driven gear 404 are ten times that of the drive gear 403. Through this size and tooth groove design, a large reduction ratio is achieved, so that the driven gear 404 only rotates once for every multiple rotations of drive gear 403. The meshing of drive gear 403 and driven gear 404 ensures that power can be transmitted from the drive gear 403 to the driven gear 404. Gear 403 transmits power to driven gear 404. A pulley 405 is fixedly connected to the rear end of the outer wall of driven gear 404. Pulley 405 rotates with driven gear 404, driving pulley 406 to rotate via drive belt 407. Pulley 406 is movably mounted on the top of support frame 401. Pulley 406 transmits power from the belt to incomplete gear 408. Drive belt 407 is fitted onto the outer walls of driven gear 404 and pulley 406. Drive belt 407 is a transmission component connecting pulley 405 and pulley 406, enabling power transmission between them. An incomplete gear is fixedly connected to the front end of the outer wall of pulley 406. Wheel 408, an incomplete gear 408 with only partial tooth grooves, is used to intermittently drive the transmission gear 409 to rotate. The transmission gear 409 is fixedly connected to the front end of the outer wall of the support shaft 306. When the transmission gear 409 meshes with the incomplete gear 408, it will drive the support shaft 306 to rotate, thereby causing the flipping mechanism 3 to flip. The incomplete gear 408 and the transmission gear 409 have the same radius to ensure that the linear speed of the two meshing transmission is consistent. The number of tooth grooves of the transmission gear 409 is twice that of the incomplete gear 408. In this way, when the incomplete gear 408 rotates one revolution, the transmission gear 409 rotates half a revolution, thereby driving the support plate 302 to flip 180 degrees, which meets the angle requirement of the tray 6 flipping. A ratchet 307 is fixedly connected to the outer wall of the support shaft 306. The ratchet 307 rotates together with the support shaft 306. Its one-way tooth structure is used to cooperate with the pawl 309 to achieve one-way limiting. A mounting plate 308 is fixedly connected to the outer wall of the support frame 301. The mounting plate 308 provides a mounting position for the pawl 309 and the spring 310. The pawl 309 is movably mounted on the outer wall of the support frame 301. Under the action of the spring 310, the pawl 309 engages with the ratchet 307, which can prevent the ratchet 307 from rotating in the opposite direction, thereby preventing the support shaft 306 and the support plate 302 from rotating in the opposite direction when not in operation, ensuring the stability of the flipping mechanism 3. The engagement of the pawl 309 with the ratchet 307 achieves one-way braking. A spring 310 is installed between the mounting plate 308 and the pawl 309. The spring 310 applies a pulling force or a pushing force to the pawl 309, so that the pawl 309 always maintains close contact with the ratchet 307, ensuring reliable braking effect. A support rod 207 is fixedly connected to the top of the side baffle 205. The support rod 207 is used to support the top tray 6 that slides down from the inclined plate 206, so that it is separated from the bottom tray 6. A pointed tip 208 is fixedly connected to one end of the support rod 207 near the inclined plate 206. The pointed tip 208 is easy to insert into the gap between the two stacked trays 6, so as to lift the top tray 6 more smoothly and realize the separation of the upper and lower trays 6. The outer wall of the support frame 101 is fixedly connected to two side baffles 106. The two side baffles 106 are located on both sides of the conveyor belt 105. The side baffles 106 can guide and limit the pallet 6 conveyed on the conveyor belt 105 to prevent the pallet 6 from deviating from the track during the conveying process. The outer walls of the inclined plate 206 are fixedly connected to two side baffles 209. The side baffles 209 are used to prevent the pallet 6 from falling from both sides when it slides down the inclined plate 206, so as to ensure that the pallet 6 can accurately enter the output production line 2. A drive motor 210 is fixedly installed on the outer wall of a side baffle 205. The drive motor 210 is the power source for the production line 2, providing power for the operation of the conveyor belt 204. The output end of the drive motor 210 is fixedly connected to one end of the drive roller 202, so that the drive motor 210 can directly drive the drive roller 202 to rotate, thereby driving the conveyor belt 204 to run. Transfer assembly 5 includes a first connecting frame 501, a support rod 502, a second connecting frame 503, a magnetic suction plate 504, and a rotating wheel 506. The first connecting frame 501 is fixedly mounted on the outer wall of the fourth supporting frame 401. The first connecting frame 501 is the main support and rotating component of transfer assembly 5, used to drive the movement of other components. The support rod 502 is fixedly connected to the outer wall of the first connecting frame 501, connecting the first connecting frame 501 and the second connecting frame 503 to transmit rotational motion. The second connecting frame 503 is movably mounted on the outer wall of the support rod 502, allowing it to rotate around the support rod 502 for easy adjustment of the magnetic suction plate 504. The angle is adjusted to allow for better contact with the tray 6. A magnetic suction plate 504 is fixedly connected to the bottom of the connecting frame 2 503. The magnetic suction plate 504 is magnetic and can attract the metal tray 6, making it easy to transfer the tray 6 from the output production line 2 to the input production line 1. A rotating wheel 506 is fixedly connected to the outer wall of the connecting frame 1 501. The rotating wheel 506 allows the operator to manually rotate the connecting frame 1 501, providing convenience for the operation of the transfer component 5. The center of the rotating wheel 506 is at the same position as the rotating part of the connecting frame 1 501 and the support frame 401, ensuring that the rotation of the rotating wheel 506 can accurately drive the connecting frame 1 501 to rotate around the rotation center. A stop bar 505 is fixedly connected to the outer wall of the support frame 401. The stop bar 505 contacts the connecting frame 501. When the connecting frame 501 rotates to the designated position, the stop bar 505 will prevent the connecting frame 501 from continuing to rotate, thus playing a limiting role and ensuring that the magnetic suction plate 504 can accurately place the tray 6 into the designated position of the input production line 1.

[0017] Working principle: First, drive motor 202 and drive motor 210 are turned on. After drive motor 202 starts, its output shaft drives drive roller 102 to start rotating. Drive roller 102, in cooperation with driven roller 103 and support roller 104, causes the conveyor belt 105, which is sleeved on their outer walls, to rotate, thereby providing power for the pallet 6 to be conveyed into production line 1. At the same time, drive motor 210 drives drive roller 202 to rotate. Drive roller 202, in cooperation with driven roller 203, causes conveyor belt 204 to rotate, preparing for the pallet 6 to be conveyed out of production line 2. During the rotation of the drive roller 102, the drive gear 403 fixedly connected to both ends of its outer wall also rotates synchronously. Since the drive gear 403 meshes with the driven gear 404 movably mounted on the top of the support frame 401, and the radius and number of tooth grooves of the driven gear 404 are ten times that of the drive gear 403, this design allows the driven gear 404 to rotate only once for every ten rotations of the drive gear 403, thus achieving the deceleration and transmission of power. When the driven gear 404 rotates, the pulley 405 fixedly connected to the rear end of its outer wall also rotates accordingly. The pulley 405 drives the pulley 406 to rotate through the drive belt 407 sleeved on its outer wall and the pulley 406. The incomplete gear 408 fixedly connected to the front end of the pulley 406 rotates synchronously. At this time, since the incomplete gear 408 is not always meshed with the transmission gear 409 at the front end of the outer wall of the support shaft 306, the two are in a separated state in the initial stage, and the support plate 302 of the flipping mechanism 3 remains stationary. The operator places a tray 6 containing bagged chicken feet on conveyor belt 105 of the input production line 1, and then inverts an empty tray 6 on top of the first tray 6, forming a tray assembly. Driven by conveyor belt 105, this tray assembly is conveyed forward along conveyor belt 105. Side baffles 106 on both sides of conveyor belt 105 limit the tray assembly to prevent it from deviating from the track during transport. When the tray assembly is conveyed to the ramp position of support frame 101, due to the transmission end of conveyor belt 105... With the end bent downwards, the tray 6 assembly will slide down the slope under its own weight and smoothly fall into the slot 304 at the top of the support plate 302 through the entry slot of the slot 304. The roller 305 inside the slot 304 will reduce the friction between the tray 6 assembly and the inner wall of the slot 304, allowing the tray 6 assembly to enter smoothly. At the same time, the horizontal baffle 303 will block the tray 6 assembly to prevent it from sliding off the rear end of the support plate 302. At this time, because the incomplete gear 408 and the transmission gear 409 have not yet meshed, the support plate 302 will not rotate and is in a waiting state.

[0018] As the drive roller 102 continues to rotate, after a cumulative ten revolutions, the conveyor belt 105 transports the next set of pallets 6 to the designated position. Simultaneously, the incomplete gear 408 rotates to mesh with the transmission gear 409. Since the incomplete gear 408 and the transmission gear 409 have the same radius, and the transmission gear 409 has twice the number of tooth grooves as the incomplete gear 408, when the incomplete gear 408 meshes with the transmission gear 409, one revolution of the incomplete gear 408 will cause the transmission gear 409 to rotate half a revolution. The transmission gear 409 is fixedly connected to the support shaft 306, thus… The support shaft 306 rotates half a turn, which in turn drives the support plate 302, which is fixedly connected to it, to rotate 180°, thus realizing the flipping of the tray 6 assembly in the slot 304. During the rotation of the support shaft 306, the ratchet 307 fixedly connected to its outer wall also rotates synchronously. At this time, the pawl 309 will slide along the tooth surface of the ratchet 307 under the elastic force of the spring 310, without hindering the forward rotation of the ratchet 307. When the support shaft 306 has a tendency to rotate in the opposite direction, the pawl 309 will engage with the ratchet 307 to prevent the support plate 302 from rotating in the opposite direction, thus ensuring the stability of the flipping action.

[0019] After the pallet 6 assembly flips 180°, the incomplete gear 408 continues to rotate and separates from the transmission gear 409, and the support plate 302 stops rotating. At this time, the flipped pallet 6 assembly slides out from the other side of the slot 304 under its own gravity and slides down the inclined plate 206. The side baffles 209 on both sides of the inclined plate 206 will prevent the pallet 6 assembly from deviating from its direction during the slide. When the pallet 6 assembly slides to the bottom of the inclined plate 206, the gap between the two pallets 6 will contact the tip 208 at one end of the support rod 207. Under the guidance of the pallet 6 assembly's own gravity and the tip 208, the bottom pallet 6 will continue to slide down onto the second conveyor belt 204. Under the limiting action of the second side baffle 205, it will be conveyed out as the second conveyor belt 204 operates, while the top pallet 6 will be lifted by the support rod 207 and remain on top of the support rod 207.

[0020] Meanwhile, on the input production line 1, a new set of pallets 6 is transported by conveyor belt 105 at the support roller 104 and falls into the slot 304 through the inlet slot of another slot 304, waiting for the next flipping action. When it is necessary to transfer the empty pallet 6 on the top of the support rod 207 to the input production line 1, the operator rotates the turntable 506. The turntable 506 drives the connecting frame 1 501 to rotate around the point of rotation between it and the support frame 401. The connecting frame 1 501 drives the connecting frame 2 503 to move through the support rod 502, so that the connecting frame 2 503... The magnetic suction plate 504 at the bottom approaches and attracts the empty tray 6 at the top of the support rod 207. Then, the rotating wheel 506 reverses and transfers the empty tray 6 to the top of the conveyor belt 105 of the input production line 1. At this time, the connecting frame 501 will contact the stop bar 505. The stop bar 505 supports and limits the connecting frame 501 to ensure that the empty tray 6 is in the correct position. The operator removes the empty tray 6 from the bottom of the magnetic suction plate 504 and places it upside down on top of the tray 6 containing chicken feet that is being conveyed on the input production line 1. This process is repeated to achieve efficient semi-automatic tray flipping operation.
