[0020] As a preferred embodiment of the dental floss box palletizing and packing production line of the present invention, wherein: a third bending plate is provided at both the front end and the back end of the palletizing box conveyor belt, a third clamping cylinder is fixedly connected to the top of the third bending plate, and a third clamping plate is fixedly connected to the back end of the third clamping cylinder at the position corresponding to the palletizing box.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention uses a flipping mechanism to drive a flipping rod and a flipping groove to perform periodic flipping actions. In conjunction with a pusher cylinder, dental floss boxes on the conveyor belt are pushed into the flipping groove one by one. After the flipping is completed, a small pusher plate pushes the dental floss box smoothly out to the next station. At the same time, multiple equally spaced cooling fan groups are set on the top of the conveyor belt to quickly cool and shape the freshly packaged dental floss boxes, avoiding deformation of the box due to excessive temperature after heat sealing.

[0023] 2. This invention, by setting up a detection mechanism, uses a transmission motor to drive the first control shaft, transmission belt, and transmission plate to move precisely along the limit rod, thereby moving the detection plate and detection cylinder to a designated position. The detection cylinder, through a vacuum generator, controls the detection suction cup to pick up the dental floss box and determine whether the product is qualified. Unqualified products are released by the detection suction cup into a hopper for unified collection. This invention realizes automated online detection and sorting of the appearance quality of dental floss boxes, significantly improving detection efficiency and consistency, and preventing defective products from entering the market.

[0024] 3. By setting up a baffle mechanism, before the detection mechanism picks up and tests the dental floss box, the baffle cylinder drives the detection baffle to descend to the surface of the palletizing conveyor belt, temporarily blocking the advancement of subsequent dental floss boxes, so that the dental floss box to be tested can be stably stopped directly below the detection suction cup, ensuring the accurate completion of the picking and testing actions. After the test is completed, the baffle cylinder drives the detection baffle to rise, effectively solving the problem of inaccurate product positioning and test failure caused by the continuous movement of the conveyor line, and creating stable working conditions for the test.

[0025] 4. This invention, by setting up a palletizing mechanism, utilizes an active motor to drive the active gear to move laterally along the active gear plate, while an auxiliary motor drives the auxiliary gear to move longitudinally along the auxiliary gear plate. This enables precise positioning of the processing composite board and the palletizing suction cup. The palletizing suction cup uses a vacuum generator to pick up the dental floss boxes from the palletizing conveyor belt and neatly place them into the palletizing box according to a preset arrangement. The back end of the support frame is also equipped with a shaft and a stabilizing plate driven by a stabilizing motor to help fix the palletizing box and prevent the box from shifting during the palletizing process. This achieves automation of dental floss box palletizing, avoids the products from being scattered and piled up at the end of the production line, significantly reduces the labor intensity of manual sorting and packing, and improves the work efficiency of the packaging process.

[0042] Example 1

[0043] The transport mechanism 100 includes a processing box 101. A processing fixing plate 102 is fixedly connected to the top of the processing box 101. A transport conveyor belt 103 is fixedly connected to the front end of the top of the processing fixing plate 102. A metal plate 104 is provided at the front end of the transport conveyor belt 103. The bottom of the metal plate 104 is fixedly connected to the top of the processing fixing plate 102. A mounting plate 105 is fixedly connected to the front end of the metal plate 104. A push cylinder 106 is fixedly connected to the top of the front end of the mounting plate 105. A push plate 107 is fixedly connected to the back end of the push cylinder 106 through to the back end of the metal plate 104.

[0044] One embodiment of this example is as follows: a flipping mechanism 200, which includes a flipping rod 201. The flipping rod 201 is disposed on the top of the processing fixed plate 102 and corresponds to the back end of the push plate 107. The left and right sides of the flipping rod 201 are fixedly connected to the flipping fixed plate 202 through a rotating shaft. The bottom of the flipping fixed plate 202 is fixedly connected to the top of the processing fixed plate 102. A flipping motor 203 is fixedly connected to the left side of the flipping fixed plate 202. The output end of the flipping motor 203 passes through the flipping fixed plate 202 and is fixedly connected to the left side of the flipping rod 201. A flipping groove 204 is fixedly connected to the surface of the flipping rod 201 and at the position corresponding to the push plate 107. Four flipping grooves 204 are provided and are evenly distributed. A small push plate 205 is fixedly connected to the back end of the inner wall of the flipping groove 204 through a pneumatic rod. A cooling fan group 206 is fixedly connected to the top of the conveyor belt 103. Several cooling fan groups 206 are provided and are evenly distributed.

[0045] The processing box 101 of the transport mechanism 100 is placed on a horizontal ground. A processing fixing plate 102 is bolted to the top of the processing box 101. A transport conveyor belt 103 is mounted on the front end of the top of the processing fixing plate 102 via a bracket. The transport conveyor belt 103 is driven by a motor and its conveying speed is adjustable. A metal plate 104 is set at the front end of the transport conveyor belt 103. The bottom of the metal plate 104 is bolted to the top surface of the processing fixing plate 102. The upper surface of the metal plate 104 is flush with the upper surface of the transport conveyor belt 103. A vertical mounting plate 105 is bolted to the front end of the metal plate 104. A push cylinder 106 is fixed to the top of the front end of the mounting plate 105 via a cylinder support. The cylinder body of cylinder 106 is horizontally positioned, with its piston rod extending rearward. A through hole is provided on the metal plate 104 for the piston rod to pass through. The back end of the pushing cylinder 106 extends through this through hole to the rear of the metal plate 104, and a pushing plate 107 is threadedly fixed to the end of the piston rod. The pushing plate 107 is a long strip plate, parallel to the width direction of the metal plate 104. The back of the pushing plate 107 is flat and is used to simultaneously push four dental floss boxes side by side. The flipping mechanism 200 is located on top of the processing and fixing plate 102 and directly behind the pushing plate 107. The flipping mechanism 200 includes a horizontally positioned flipping rod 201, which is a square hollow rod. The left and right ends of the flipping rod 201 are respectively fitted with rotating shafts through keyways. The rotating shafts are rotatably connected to two flipping fixing plates 202 via bearings. Both flipping fixing plates 202 are vertically arranged metal plates, and their bottoms are fixed to the top of the processing fixing plate 102 by bolts. A flipping motor 203 is fixedly connected to the outer side of the left flipping fixing plate 202 via a motor mounting bracket. The flipping motor 203 is a servo motor, and its output shaft extends horizontally to the right, passes through the shaft hole opened on the left flipping fixing plate 202, and is fixedly connected to the rotating shaft at the left end of the flipping rod 201 via a coupling. The rotation angle and speed of the flipping motor 203 are precisely controlled by a controller. On the outer surface of the flipping rod 201, four flipping slots 204 are fixedly connected at equal intervals along its length. The positions of the four flipping slots 204 are relative to the push plate 102. The push areas of 07 correspond one-to-one. Each flipping slot 204 is an open slot, and its inner width is slightly larger than the width of the dental floss box, so that the dental floss box can fall smoothly into the flipping slot 204. A small push plate 205 is fixedly connected to the back of the inner wall of each flipping slot 204 by a miniature air rod. Whenever the flipping slot 204 flips 180° from receiving the dental floss box, the air rod extends, and the small push plate 205 pushes the dental floss box in the flipping slot 204 backward, so that it is removed from the flipping slot 204 and falls onto the palletizing conveyor belt 301. Directly above the transport conveyor belt 103, several cooling fan groups 206 are fixedly connected by multiple L-shaped brackets. The cooling fan groups 206 are evenly distributed along the conveying direction of the transport conveyor belt 103.The fan outlet points vertically downwards towards the upper surface of the conveyor belt 103 to force-cool the passing dental floss boxes, reducing their surface temperature and preventing overheating. During operation, the dental floss boxes are placed onto the conveyor belt 103 from upstream equipment, and the conveyor belt 103 transports them backwards. As they pass under the cooling fan assembly 206, cold air cools the dental floss boxes. When the dental floss boxes are transported to the metal plate 104 and reach the pushing position, the laser sensor detects the product's arrival and controls the pushing cylinder 106 to extend. The pushing plate 107 simultaneously pushes four dental floss boxes backwards into the corresponding flipping slots 204 on the flipping rod 201. Then, the flipping motor 203 drives the flipping rod 201 to rotate 90°, changing the opening of the flipping slot 204 from facing forward to facing upward. Then, after the next set of dental floss boxes arrives, the flipping continues. After another 90° rotation, the micro-sized dental floss boxes in the flipping slot 204... The pneumatic rod extends, and the small pusher 205 pushes the dental floss box out of the flipping groove 204, where it falls onto the palletizing conveyor belt 301. This process is repeated sequentially. By setting up a flipping mechanism 200, the dental floss boxes conveyed by the transport conveyor belt 103 can be automatically pushed into the flipping groove 204 one by one. The flipping motor 203 drives the flipping rod 201 to drive the flipping groove 204 to complete a periodic flipping action, smoothly changing the dental floss box from a horizontal position to the desired position. After flipping to the correct position, the small pusher 205 pushes it out to the next station. Simultaneously, the cooling fan assembly 206 on top of the transport conveyor belt 103 can quickly cool the heat-sealed dental floss box, preventing overheating. This solves the problems of low efficiency due to manual operation and overheating associated with flipping dental floss boxes, achieving integrated automatic operation of flipping, cooling, and conveying, effectively improving the overall operational stability of the production line and product quality.

[0046] A laser sensor 104a is fixedly connected to the top of the metal plate 104 and the position corresponding to the push cylinder 106. There are four laser sensors 104a, which are evenly distributed.

[0047] At the top of the metal plate 104, corresponding to the position of each dental floss box, a laser sensor 104a is fixedly installed. Four equally spaced laser sensors 104a are machined and installed on the upper surface of the metal plate 104, with their transmitting and receiving ends integrated into one unit. The laser beam is emitted downwards perpendicular to the upper surface of the metal plate 104. The four laser sensors 104a are evenly distributed along the width direction of the metal plate 104, with the detection head of each laser sensor 104a facing the bottom of the dental floss box passing overhead. When the dental floss box is delivered to the metal plate 104 by the conveyor belt 103 and exactly covers the position of the laser sensor 104a, the pusher plate 107 smoothly pushes all four dental floss boxes into the flipping groove 204 in one go. If any laser sensor 104a does not detect a product... When a product is in stock, the push cylinder 106 remains retracted, waiting for subsequent products to be replenished. By setting four equally spaced laser sensors 104a, multi-station synchronous detection and linkage control can be achieved. The laser sensors 104a accurately sense whether there is a dental floss box in place at each push station. Only when all four stations have material will the push cylinder 106 perform the push action, thereby avoiding the problem of empty push or uneven push due to lack of material. This ensures that the flipping slot 204 can be fully loaded with four dental floss boxes each time, improving the utilization rate and palletizing efficiency of the flipping mechanism 200. It realizes the automatic start and stop of the push action, solving the problems of missed push, wrong push, and asynchronous multi-station operation caused by traditional manual visual inspection or mechanical triggering push methods, and improving the efficiency of automated operation of the production line.

[0048] A side plate 102a is fixedly connected to the top of the processing fixed plate 102 and to the left and right sides of the palletizing conveyor belt 301. A first bending plate 102b is fixedly connected to the right side of the side plate 102a and to the front end of the hopper 314. A first clamping cylinder 102c is fixedly connected to the top of the first bending plate 102b. A first clamping plate 102d is fixedly connected to the left side of the first clamping cylinder 102c and to the top of the palletizing conveyor belt 301.

[0049] At the top of the processing fixed plate 102, on the left and right sides of the palletizing conveyor belt 301, vertically arranged side plates 102a are fixedly connected by bolts. Their length direction is consistent with and parallel to the conveying direction of the palletizing conveyor belt 301. Each side plate 102a has multiple equally spaced threaded holes machined at its bottom, which are fixedly connected to the pre-set threaded holes on the processing fixed plate 102 by internal angle bolts. On the right side plate 102a, corresponding to the front end of the hopper 314, a first bending plate 102b is fixedly connected by bolts. The first bending plate 102b is an L-shaped piece and is fixedly attached to the outer side of the right side plate 102a, forming a horizontal mounting platform at its top. On the horizontal mounting platform at the top of the first bending plate 102b, a first clamping cylinder 102c is fixedly connected by a cylinder support. On the left side of the first clamping cylinder 102c, a first clamping plate 102d is connected by a connector. The first clamping plate 102d is a rectangular plate, and its length direction is parallel to the conveying direction of the palletizing conveyor belt 301. When the dental floss box is conveyed to the detection position by the palletizing conveyor belt 301, the sensor feeds back a signal, controlling the piston rod of the first clamping cylinder 102c to extend to the left, pushing the first clamping plate 102d to push the dental floss box on the palletizing conveyor belt 301, thus achieving the centering and positioning of the product. After the clamping action is completed, the piston rod of the first clamping cylinder 102c retracts, and the first clamping plate 102d resets. This is achieved by setting the side plates 102a on both sides and the first bending plate 102b, the first clamping cylinder 102c, and the first... The lateral clamping and positioning device composed of clamping plates 102d can realize the automatic centering and precise positioning of dental floss boxes on the palletizing conveyor belt 301. When the dental floss box passes through the front area of ​​the detection, the first clamping plate cylinders 102c on both sides drive the first clamping plates 102d to clamp the product inward, making it neat and uniform. This eliminates the lateral positional offset of the dental floss box caused by conveying vibration or guide deviation, ensuring that the subsequent detection suction cup 313 can accurately align with the center of each dental floss box, improving the success rate and consistency of suction.

[0050] A second bending plate 102e is fixedly connected to the back end of the right side of the side plate 102a and to the back end of the first fixing frame 302. A second clamping cylinder 102f is fixedly connected to the top of the second bending plate 102e. A second clamping plate 102g is fixedly connected to the left side of the second clamping cylinder 102f and to the top of the palletizing conveyor belt 301.

[0051] On the back end of the right-side side plate 102a, that is, at the rear end along the conveying direction of the palletizing conveyor belt 301, near the back end of the first fixed frame 302, a second bent plate 102e is fixedly connected by bolts. The second bent plate 102e has a similar structure to the first bent plate 102b, using an L-shaped sheet metal to form a horizontal mounting platform at the top. The installation position of the second bent plate 102e corresponds to the back end of the first fixed frame 302, so as to reposition the dental floss box after inspection before the palletizing process. On the horizontal mounting platform on the top of the second bent plate 102e, by... A second clamping cylinder 102f is fixedly connected to the cylinder support. The second clamping cylinder 102f is the same model as the first clamping cylinder 102c. A second clamping plate 102g is connected to the left side of the second clamping cylinder 102f via a connector. The second clamping plate 102g is a rectangular plate, and its length direction is parallel to the conveying direction of the palletizing conveyor belt 301. The second clamping cylinder 102f operates after the inspection mechanism 300 completes the inspection and the qualified product is returned to the palletizing conveyor belt 301, and before the palletizing mechanism 500 picks it up. When the dental floss box is conveyed to the station where the second clamping plate 102g is located, i.e. When the palletizing conveyor belt 301 reaches its final position, the position sensor detects that four columns of five products each (i.e., twenty products) have arrived and issues a command to extend the piston rod of the second clamping cylinder 102f to the left. This pushes the second clamping plate 102g to neatly align the dental floss boxes on the palletizing conveyor belt 301 towards the center, ensuring that their left side is flush against the left side plate 102a. This completes the second centering and positioning. By using the second bending plate 102e, the second clamping cylinder 102f, and the second clamping plate 102g, the dental floss boxes can be precisely positioned a second time after inspection and before entering the palletizing station. During the suction, return, and transport processes, the suction cup 313 may shift again, affecting the suction accuracy of the palletizing suction cup 522. The second clamping plate cylinders 102f on both sides drive the second clamping plate 102g to push the product to the center point, ensuring that each column and each row of dental floss boxes is in the predetermined coordinate position. This structure, together with the first clamping plate cylinder 102c, forms two positioning processes, serving the two key links of inspection and palletizing respectively. This solves the problem of product position shift after multiple operations in the existing production line, which leads to palletizing failure or uneven arrangement, and improves the regularity of the palletizing mechanism 500.

[0052] Example 2

[0053] Based on Embodiment 1, this embodiment considers that in the dental floss box packaging production line, the product appearance quality inspection still relies on manual visual inspection one by one. This is not only slow and prone to fatigue and missed inspections, but also lacks unified standards, leading to defective products mixing with qualified products and entering the market. Therefore, this embodiment sets up an inspection mechanism 300. The inspection mechanism 300 includes a palletizing conveyor belt 301. The bottom of the palletizing conveyor belt 301 and the top of the processing fixing plate 102 are fixedly connected to the back end of the corresponding flipping groove 204. The top of the processing fixing plate 102 is fixedly connected to a first fixing frame 302. The front end of the first fixing frame 302 is fixedly connected to a rectangular long plate 303. The left and right sides of the front end of the rectangular long plate 303 are movably connected to a first control shaft 304 and a second control shaft 305 through rotating shafts. The first control shaft 304 is located to the left of the second control shaft 305. The back end of the rectangular long plate 303 and the back end of the first control shaft 304 are fixedly connected to a drive motor 306. The output end of the drive motor 306 passes through the front end of the rectangular long plate 303 and the first control shaft 305. The back end of the control shaft 304 is fixedly connected. A transmission belt 307 is movably sleeved on the surface of the first control shaft 304. A section of the transmission belt 307 away from the first control shaft 304 is sleeved on the surface of the second control shaft 305. The first control shaft 304 and the second control shaft 305 are connected by transmission belt 307. A transmission plate 308 is fixedly connected to the top of the transmission belt 307. A limit plate 309 is fixedly connected to the bottom of the back end of the transmission plate 308. A limit rod 310 is slidably connected to the back end of the limit plate 309. The back end of 10 is fixedly connected to the front end of the rectangular plate 303. The bottom of the transmission plate 308 is fixedly connected to the detection plate 311. The left and right sides of the front end of the detection plate 311 are fixedly connected to the detection cylinder 312. The bottom of the detection cylinder 312 is fixedly connected to the detection suction cup 313 through the vacuum generator. There are four detection suction cups 313 and they are evenly distributed. The top of the processing fixed plate 102 and the bottom of the detection suction cup 313 and the left and right sides of the palletizing conveyor belt 301 are fixedly connected to the hopper 314.

[0054] The inspection mechanism 300 includes a palletizing conveyor belt 301. The bottom of the palletizing conveyor belt 301 is bolted to the top of the processing fixing plate 102, and the front end corresponds to the back end of the flipping groove 204 to receive the cooled dental floss boxes sent out from the flipping mechanism 200. The palletizing conveyor belt 301 is driven by a stepper motor, and the conveying direction is from front to back. The running speed matches the output of the flipping mechanism 200. On the top of the processing fixing plate 102, located on one side of the palletizing conveyor belt 301, a first fixing frame 302 is bolted to it. The first fixing frame 302 is a gantry-type metal frame structure, welded together, and is in an inverted U-shape, spanning above the palletizing conveyor belt 301. The front end of the first fixing frame 302 is bolted to a piece of... A rectangular plate 303 has a first control shaft 304 and a second control shaft 305 rotatably connected to its left and right front ends via bearing mounts, respectively. The first control shaft 304 is located on the left side, and the second control shaft 305 is located on the right side, with parallel axes at the same horizontal level. A drive motor 306, a servo motor, is fixedly connected to the back end of the rectangular plate 303, corresponding to the position of the first control shaft 304, via a motor bracket. Its output shaft extends horizontally in the front-rear direction, passes through a through hole in the rectangular plate 303, and is fixedly connected to the back end of the first control shaft 304 via a coupling. A drive belt 307, a synchronous toothed belt, is movably sleeved on the surface of the first control shaft 304. The inner teeth of the transmission belt 307 mesh with the synchronous pulleys on the surfaces of the first control shaft 304 and the second control shaft 305. A section of the transmission belt 307 away from the first control shaft 304 is sleeved on the surface of the second control shaft 305, thus enabling synchronous transmission between the first control shaft 304 and the second control shaft 305 via the transmission belt 307. A transmission plate 308 is fixedly connected to the top of the upper section of the transmission belt 307 by screws. The transmission plate 308 is a rectangular metal plate, its length parallel to the length of the rectangular long plate 303. A limiting plate 309 is welded or bolted to the bottom of the back end of the transmission plate 308. The limiting plate 309 is an L-shaped bent piece with a groove on its back end. A limiting rod 310 is slidably connected within this groove. The end is fixedly connected to the front end face of the rectangular plate 303 by threads, and the axis of the limiting rod 310 is parallel to the moving direction of the transmission belt 307. The sliding engagement between the limiting plate 309 and the limiting rod 310 guides the movement of the transmission plate 308. A detection plate 311 is fixedly connected to the bottom of the transmission plate 308 by multiple vertical connecting rods. The detection plate 311 is a rectangular flat plate. A detection cylinder 312 is fixedly connected to the left and right sides of the front end of the detection plate 311 by bolts. The cylinder body is installed vertically downward, and the bottom of its piston rod is fixedly connected to a detection suction cup 313, which is controlled by a vacuum generator. Each detection cylinder 312 has four detection suction cups 313 at its bottom, and the four suction cups stably pick up a single dental floss box.Two detection cylinders 312 have a total of eight detection suction cups 313. At the top of the processing fixing plate 102, on the left and right sides of the palletizing conveyor belt 301, and directly below each detection suction cup 313, a hopper 314 is fixedly connected to each. The hopper 314 is a stamped funnel-shaped part, with its outlet leading to a defective product collection box. The left and right hoppers 314 are symmetrically arranged to receive defective dental floss boxes released from the detection suction cups 313, preventing confusion between qualified and defective products. By setting up the detection mechanism 300, the automated online detection of the appearance quality of the dental floss boxes and the rejection of defective products are realized. The drive motor 306 drives the first control shaft 304 to rotate, which is connected to the transmission belt 314. 07 drives the transmission plate 308 and detection plate 311 to move laterally along the limit rod 310 to directly above the palletizing conveyor belt 301. The detection cylinder 312 descends, causing the detection suction cup 313 to contact the surface of the dental floss box. The vacuum generator activates and holds the product. The vacuum generator has a critical value; if the corresponding value of the dental floss box is less than the preset negative pressure value, the product is considered unqualified. At this time, the detection cylinder 312 rises, and the transmission motor 306 again drives the detection plate 311 to move laterally, causing the sucked dental floss box to be lowered above the slide 314. This effectively solves the problems of missed inspections, false inspections, and low efficiency caused by manual inspection, ensuring that only qualified products enter the subsequent palletizing process. Simultaneously, the detection cylinders 312 on both sides work together, increasing the efficiency of the inspection process.

[0055] Example 3

[0056] Based on Embodiment 2, this embodiment considers that the detection mechanism 300 in Embodiment 2 can realize the automated detection and defective product rejection of dental floss boxes. However, there is still a problem that when the detection suction cup 313 descends to pick up the dental floss box to be detected on the palletizing conveyor belt 301, the dental floss box is continuously conveyed forward under the drive of the palletizing conveyor belt 301, which is prone to displacement. At the same time, it may also cause subsequent products to accumulate at the workstation, affecting the subsequent palletizing process. Therefore, this embodiment sets up a baffle mechanism 400. The baffle mechanism 400 includes a vertical plate 401. The bottom of the vertical plate 401 is fixedly connected to the top of the processing fixed plate 102. A baffle cylinder 402 is fixedly connected to the front end of the vertical plate 401. A detection baffle 403 is fixedly connected to the bottom of the baffle cylinder 402. The baffle cylinder 402 is used in conjunction with a vacuum generator.

[0057] The baffle mechanism 400 includes a vertical plate 401, the bottom of which is bolted to the top of the processing fixing plate 102. The vertical plate 401 is inverted U-shaped and its bottom is located on both sides of the palletizing conveyor belt 301, at the bottom of the first fixing frame 302. A baffle cylinder 402 is fixedly connected to the front end of the vertical plate 401 via a cylinder support. The cylinder body is installed vertically downward, meaning the piston rod extends vertically downward. A detection baffle 403 is threaded to the bottom of the baffle cylinder 402. The detection baffle 403 is a rectangular flat plate, and its lower surface is parallel to the upper surface of the palletizing conveyor belt 301. When the piston rod of the baffle cylinder 402 is fully extended, the gap between the lower surface of the detection baffle 403 and the upper surface of the palletizing conveyor belt 301 is 1-2 mm, ensuring that the dental floss box can be effectively blocked from advancing without scratching the conveyor belt. The baffle cylinder 402 works in conjunction with the vacuum generator. When the detection suction cup 313 needs to pick up the dental floss box, it sends a command to cause the piston rod of the baffle cylinder 402 to extend rapidly. The detection baffle 403 descends to the surface of the palletizing conveyor belt 301, blocking the dental floss box from moving forward. Then, the detection suction cup 313 descends and starts vacuuming to pick up the dental floss box to be inspected. After the picking is completed, it sends a command to cause the piston rod of the baffle cylinder 402 to retract, and the detection baffle 403 rises to release the blocked product. By setting the baffle mechanism 400, the function of temporarily blocking the product conveying when the detection suction cup 313 picks up the dental floss box is realized. When the dental floss box to be inspected is conveyed to the bottom of the detection suction cup 313, the baffle cylinder 402 drives the detection baffle 403 to descend, blocking the dental floss box at the inspection station, thereby avoiding misalignment between the product and the inspection structure and ensuring that the detection suction cup 313 can pick up the product stably and accurately.

[0058] Example 4

[0059] Based on Embodiment 2, this embodiment considers that the detection mechanism 300 in Embodiment 2 can realize the detection and rejection of dental floss boxes. However, there is still a problem that after qualified products are detected, they are transported to the end of the production line by the palletizing conveyor belt 301. Due to the lack of automatic sorting and palletizing devices, the dental floss boxes are scattered and piled up at the end of the conveyor belt, requiring sorting and loading into the palletizing box 503. Therefore, this embodiment sets up a palletizing mechanism 500. The palletizing mechanism 500 includes a support frame 501. The front end of the support frame 501 is fixedly connected to the back end of the processing box 101. A support plate 502 is fixedly connected to the bottom of the back end of the support frame 501. A palletizing box conveyor is fixedly connected to the top of the support plate 502. The conveyor belt 502a has several palletizing boxes 503 on its top. A second fixed frame 504 is fixedly connected to the top of the support frame 501. A main transverse rod 505 is fixedly connected to the left side of the second fixed frame 504. The front end of the main transverse rod 505 is fixedly connected to the back end of the first fixed frame 302. A support rod 506 is fixedly connected to the back end of the main transverse rod 505. The bottom of the front end of the support rod 506 is fixedly connected to the back end of the support plate 502. A transverse slide plate 507 is fixedly connected to the left side of the main transverse rod 505. A transverse limiting block 508 is slidably connected to the left side of the transverse slide plate 507. The transverse limiting block 508 is... There are four: a connecting plate 509 is fixedly connected to the left side of the transverse limiting block 508; a longitudinal limiting block 510 is fixedly connected to the left side of the connecting plate 509; there are two longitudinal limiting blocks 510; a longitudinal slide plate 511 is slidably connected to the left side of the longitudinal limiting block 510; a secondary longitudinal rod 512 is fixedly connected to the left side of the longitudinal slide plate 511; a triangular fixing plate 513 is fixedly connected to the top right side of the connecting plate 509; a drive motor 514 is fixedly connected to the right side of the triangular fixing plate 513; a drive gear 515 is fixedly connected to the output end of the drive motor 514 through the inner wall of the triangular fixing plate 513; and a drive gear plate 516 is fixedly connected to the top of the main transverse rod 505. The top of the toothed plate 516 is meshed with the bottom of the drive gear 515. The left side of the connecting plate 509 is fixedly connected to the motor plate 517, and the right side of the motor plate 517 is fixedly connected to the auxiliary motor 518. The output end of the auxiliary motor 518 passes through the left side of the motor plate 517 and is fixedly connected to the auxiliary gear 519. The front end of the auxiliary longitudinal rod 512 is fixedly connected to the auxiliary toothed plate 520. The front end of the auxiliary toothed plate 520 is meshed with the back end of the auxiliary gear 519. The bottom of the auxiliary longitudinal rod 512 is fixedly connected to the processing composite plate 521. The bottom of the processing composite plate 521 is fixedly connected to the palletizing suction cup 522 through the vacuum generator. The palletizing suction cup 522 is arranged in four rows with five in each row.

[0060] The palletizing mechanism 500 includes a support frame 501, which is a frame structure welded from square steel. The front end of the support frame 501 is fixedly connected to the back end face of the processing box 101 by bolts. A support plate 502 is fixedly connected to the bottom of the back end of the support frame 501 by bolts. A palletizing box conveyor belt 502a is fixedly connected to the top of the support plate 502. Several palletizing boxes 503 are placed on the top of the palletizing box conveyor belt 502a. The palletizing boxes 503 are paper turnover boxes, and their internal dimensions match the arrangement dimensions of the dental floss boxes. Each layer of each palletizing box 503 can accommodate four rows of five dental floss boxes. The palletizing boxes 503 are placed sequentially on the palletizing box conveyor belt 502a by manual or automatic box feeding devices and move with the conveyor belt. A second fixed frame 504 is fixedly connected to the top of 501. The second fixed frame 504 is also a frame structure welded from square steel and is located above the palletizing box conveyor belt 502a. A main transverse bar 505 is fixedly connected to the left side of the second fixed frame 504 by bolts. The main transverse bar 505 has a rectangular cross section and is horizontally arranged along the front-to-back direction. The front end of the main transverse bar 505 is fixedly connected to the back end of the first fixed frame 302 in the detection mechanism 300 by bolts, so that the main transverse bar 505 and the first fixed frame 302 form a rigid support. A vertical support bar 506 is fixedly connected to the back end of the main transverse bar 505 by bolts. The bottom of the support bar 506 is fixedly connected to the back end of the support plate 502 to reinforce the main transverse bar 501. To ensure stability, a transverse slide plate 507 is fixedly connected to the left side of the main transverse rod 505 by screws. The transverse slide plate 507 is aligned with the length direction of the main transverse rod 505. Four transverse limiting blocks 508 are slidably connected to the left side of the transverse slide plate 507. Each transverse limiting block 508 is a slider that cooperates with the transverse slide plate 507. The four transverse limiting blocks 508 are evenly spaced along the length direction of the transverse slide plate 507. A connecting plate 509 is fixedly connected to the left side of the four transverse limiting blocks 508 by bolts. It is parallel to the transverse slide plate 507. Two longitudinal limiting blocks 510 are fixedly connected to the left side of the connecting plate 509 by bolts. The two longitudinal limiting blocks 510 are arranged vertically. All components are slider structures. A longitudinal slide plate 511 is slidably connected to the left side of the longitudinal limiting block 510. The longitudinal slide plate 511 is perpendicular to the transverse slide plate 507. A secondary longitudinal rod 512 is bolted to the left side of the longitudinal slide plate 511. A triangular fixing plate 513 is bolted to the top right side of the connecting plate 509. The triangular fixing plate 513 is a right-angled triangular reinforcing plate used to enhance the installation rigidity of the active motor 514. An active motor 514 is fixedly connected to the right side of the triangular fixing plate 513 via a motor bracket. The active motor 514 is a servo motor, with its output shaft extending horizontally to the left. After passing through a through hole in the triangular fixing plate 513, an active gear 515 is connected and fixed therethrough.A drive gear plate 516 is bolted to the top of the main transverse rod 505 along its length. The drive gear plate 516 is a steel rack with its tooth surface facing upwards. Its tooth profile matches that of the drive gear 515. The bottom of the drive gear 515 meshes with the top of the drive gear plate 516. When the drive motor 514 rotates, the drive gear 515 rolls along the drive gear plate 516, thereby driving the connecting plate 509 and the entire transverse moving assembly to move back and forth along the transverse slide plate 507. A motor plate 517 is bolted to the left side of the connecting plate 509. The vertical surface of the motor plate 517 is fixed to the connecting plate 509. An auxiliary motor 518 is fixed to the right side of the motor plate 517. The auxiliary motor 518 is also a servo motor. Its output shaft is horizontally to the left. After the output shaft of the auxiliary motor 518 passes through the left side of the motor plate 517, an auxiliary gear 519 is fixedly connected by a key. The front end of the auxiliary longitudinal rod 512 is fixedly connected by bolts to an auxiliary gear plate 520. The auxiliary gear plate 520 is a steel rack with its tooth surface facing forward. The back end of the auxiliary gear 519 meshes with the front end of the auxiliary gear plate 520. When the auxiliary motor 518 rotates, the auxiliary gear 519 rolls along the auxiliary gear plate 520, thereby driving the auxiliary longitudinal rod 512 and the longitudinal slide plate 511 fixed thereto to move up and down along the longitudinal limit block 510. The bottom of the auxiliary longitudinal rod 512 is fixedly connected to a processing composite plate 521 by multiple vertical connecting columns. The bottom of the processing composite plate 521 is fixed. A palletizing suction cup 522 is fixedly connected and controlled by a vacuum generator. The palletizing suction cups 522 are arranged in a matrix of four columns with five cups per column, for a total of twenty cups. The center distance of each suction cup is consistent with the spacing of the dental floss boxes in the palletizing box 503. The palletizing suction cups 522 are connected to the vacuum generator via air pipes. The vacuum generator and control valve assembly are installed on the top of the processing composite plate 521 or on the support frame 501 and are coordinated by the controller. During operation, the palletizing conveyor belt 301 transports qualified dental floss boxes to the palletizing area and simultaneously transports empty palletizing boxes 503 to a predetermined position. The active motor 514 and the auxiliary motor 518 are controlled to move in coordination, causing the processing composite plate 521 to move the palletizing suction cups 522 directly above the dental floss box assembly to be picked up. The active motor 518 drives the secondary longitudinal rod 512 to descend, where it is adsorbed by a vacuum suction cup. Then, through lateral and longitudinal movement, the dental floss box is transported to the corresponding position in the palletizing box 503. This action is repeated until the palletizing box 503 is full. After it is full, the palletizing box conveyor belt 502a steps forward to move the next empty box into the working position. By setting up the palletizing mechanism 500, the precise stacking and placement of boxes is achieved. The active motor 514 drives the connecting plate 509 to move back and forth along the transverse slide plate 507 through the meshing of the active gear 515 and the active toothed plate 516. The secondary motor 518 drives the secondary longitudinal rod 512 to move up and down along the longitudinal limiting block 510 through the meshing of the secondary gear 519 and the secondary toothed plate 520. The two work together to achieve precise positioning of the processed composite plate 521 in the horizontal plane.The 522 palletizing suction cup adopts a four-column, five-row matrix layout, capable of simultaneously picking up twenty dental floss boxes. This solves the problem of dental floss boxes piling up haphazardly at the end of the production line, resulting in low efficiency and potential product damage from manual handling. It improves production efficiency while ensuring consistent and stable stacking.

[0061] A rectangular plate 501a is fixedly connected to the back end of the support frame 501. Rectangular rods 501b are fixedly connected to the left and right sides of the top of the back end of the rectangular plate 501a. A long rod 501c is movably connected to the back end of the rectangular rod 501b through a pivot. A shaft 501d is movably connected to the back end of the long rod 501c through a pivot. The back end of the shaft 501d is fixedly connected to the front end of the support rod 506. A stabilizing plate 501e is fixedly sleeved on the surface of the shaft 501d at the position corresponding to the palletizing box 503. Two stabilizing plates 501e are provided.

[0062] A rectangular plate 501a is bolted to the back end of the support frame 501. The rectangular plate 501a is a vertically arranged steel plate. At the top of the back end of the rectangular plate 501a, a rectangular rod 501b is bolted to both the left and right sides. Both rectangular rods 501b are solid steel, extending horizontally backward with equal lengths and parallel to each other. A long rod 501c is movably connected to the back end of each rectangular rod 501b via a pivot. The two long rods 501c are of equal length, and their back ends are connected via a pivot. The shaft is movably connected by a common shaft 501d, which is horizontally positioned with its axis running left-right. The rear end of the left-side long rod 501c is connected to the left end of the shaft 501d via a pivot, and the rear end of the right-side long rod 501c is connected to the right end of the shaft 501d via a pivot. The back end of the shaft 501d is fixedly connected to the front end of a support rod 506, which is a vertically positioned square steel tube. Its front end is fixedly connected to the middle of the shaft 501d by welding or bolts. Corresponding codes are marked on the surface of the shaft 501d. A stabilizing plate 501e is fixedly fitted to the position of the pallet box 503. Two stabilizing plates 501e are provided, symmetrically distributed front and back. Each stabilizing plate 501e is a rectangular flat plate, fixed to the shaft 501d with screws. The lower edge of the stabilizing plate 501e extends to the vicinity of the side wall of the pallet box 503, used to hold the pallet box 503 in place during palletizing, preventing lateral or longitudinal displacement due to the picking and placing actions of the palletizing suction cup 522 or vibration of the conveyor belt. This is achieved by setting rectangular plates 501a, rectangular rods 501b, long rods 501c, and shafts. Rod 501d and stabilizing plate 501e provide auxiliary positioning and stable support for palletizing box 503 during the palletizing process. Rectangular rod 501b, long rod 501c and shaft 501d form a linkage mechanism, which allows stabilizing plate 501e to be adjusted according to the position of palletizing box 503 while maintaining contact with the box body. The two stabilizing plates 501e are close to palletizing box 503 from the left and right sides respectively, ensuring that dental floss boxes can fall accurately into the predetermined position inside the box and will not be blocked by the carton opening on the box body, thus improving the neatness and success rate of palletizing.

[0063] A stabilizing motor 501f is fixedly connected to the inner cavity of the rectangular plate 501a. The output end of the stabilizing motor 501f passes through the back end of the rectangular plate 501a. The output end of the stabilizing motor 501f and the shaft 501d are connected by a transmission belt.

[0064] A rectangular cavity is formed inside the rectangular plate 501a by an inward recess from the back of the plate. A stabilizing motor 501f, a servo motor, is fixedly connected within this cavity via a motor bracket and a shock-absorbing pad. A through hole is provided on the back end of the rectangular plate 501a corresponding to the output shaft of the stabilizing motor 501f. The output end of the stabilizing motor 501f passes through this through hole and extends to the outside of the back end of the rectangular plate 501a. A drive pulley is fixedly installed at the end of the output shaft of the stabilizing motor 501f. A drive pulley is fixedly installed at the corresponding position on the shaft 501d. The driving pulley and the driven pulley are connected by a transmission belt, thereby realizing the power transmission between the output shaft of the stabilizing motor 501f and the shaft 501d. The transmission belt drives the shaft 501d to rotate synchronously, which in turn drives the two stabilizing plates 501e fixedly sleeved on the shaft 501d to swing, thereby supporting the opening of the palletizing box 503. By setting the stabilizing motor 501f and its transmission belt connection with the shaft 501d, the active rotation of the stabilizing plates 501e is realized. According to the control command, the shaft 501d is precisely driven to rotate a certain angle, thereby changing the tilt angle of the two stabilizing plates 501e.

[0065] The front and back ends of the palletizing box conveyor belt 502a are both provided with a third bending plate 502a-1. The top of the third bending plate 502a-1 is fixedly connected to a third clamping cylinder 502a-2. The back end of the third clamping cylinder 502a-2 and the position corresponding to the palletizing box 503 are fixedly connected to a third clamping plate 502a-3.

[0066] A third bending plate 502a-1 is respectively installed at the front and back ends of the palletizing box conveyor belt 502a. The two third bending plates 502a-1 have the same structure, and their planes are parallel to the upper surface of the palletizing box conveyor belt 502a. On the horizontal mounting plate of each third bending plate 502a-1, a third clamping cylinder 502a-2 is fixedly connected by a cylinder support. A third clamping plate 502a-3 is fixedly connected to the back end of the third clamping cylinder 502a-2 through a connector. The third clamping plate 502a-3 is rectangular. During operation, the third clamping cylinders 502a-2 at the front and back ends of the flat plate simultaneously drive their third clamping plates 502a-3 to extend, which are used to position the palletizing box 503, clamp the palletizing box 503, and prevent the palletizing box 503 from being misaligned until the palletizing is completed. By setting two third bending plates 502a-1 at the front and rear ends and their third clamping cylinders 502a-2 and third clamping plates 502a-3, the box body is prevented from shaking or shifting during the process of the palletizing suction cup 522 picking up and putting down the dental floss box, thus improving the neatness of the palletizing.

[0067] Working principle: The dental floss box enters the conveyor belt 103, and the conveyor belt 103 transports the dental floss box to the left. When it passes the cooling fan group 206 above the conveyor belt 103, the cooling fan group 206 blows cold air downwards to force the dental floss box, which has just been heat-sealed, to be cooled and its surface temperature is reduced.

[0068] After cooling, the dental floss boxes continue to be conveyed to the metal plate 104. Four laser sensors 104a are evenly distributed on the top of the metal plate 104. Each laser sensor 104a detects whether a dental floss box is in place at its corresponding station. When all four laser sensors 104a detect a dental floss box at the same time, the controller issues a command, and the piston rod of the push cylinder 106 extends, driving the push plate 107 to push the four dental floss boxes backward into the flipping slots 204 of the flipping mechanism 200 at one time. The flipping rod 201 of the flipping mechanism 200 is fixed with four evenly distributed flipping slots 204. After the four dental floss boxes are pushed into the flipping slots 204, the flipping motor 203 drives the flipping rod 201 to rotate 90°. After flipping into place, the air rod at the back end of the inner wall of the flipping slot 204 extends, pushing the small push plate 205 to push the dental floss box out of the flipping slot 204 and smoothly fall onto the palletizing conveyor belt 301 behind. The flipping rod 201 resets, waiting for the next set of dental floss boxes.

[0069] After the dental floss box falls onto the palletizing conveyor belt 301, it is conveyed backward by the palletizing conveyor belt 301. Before entering the inspection station, the first clamping cylinder 102c drives the first clamping plate 102d to push the dental floss box from the side, centering it and ensuring that the dental floss box is directly below the inspection suction cup 313. When the dental floss box reaches the inspection station, the baffle cylinder 402 drives the inspection baffle 403 to descend to the surface of the palletizing conveyor belt 301, temporarily blocking the forward movement of the dental floss box, so that the dental floss box to be inspected is stably stopped below the inspection suction cup 313. The drive motor 306 of the inspection mechanism 300 drives the first control shaft 304 to rotate, which drives the transmission plate 308 and the inspection plate 311 along the transmission belt 307. The limit rod 310 moves, causing the detection suction cup 313 to move directly above the dental floss box to be tested. The detection cylinder 312 descends, and the detection suction cup 313 contacts the surface of the dental floss box. The vacuum generator starts, sucking up the dental floss box. After the detection cylinder 312 rises, the drive motor 306 drives the detection plate 311 to move laterally again, so that the sucked dental floss box is tested by the negative pressure gauge set by the vacuum generator. If the product is unqualified, the detection suction cup 313 moves the dental floss box above the slide 314, cuts off the vacuum, and makes it fall into the slide 314. It then slides into the defective product collection box through the slide 314. After the test is completed, the baffle cylinder 402 drives the detection baffle 403 to rise, and the next round of testing continues.

[0070] The qualified dental floss boxes continue to be conveyed to the end along the palletizing conveyor belt 301. The second clamping cylinder 102f drives the second clamping plate 102g to push the dental floss box from the side again, so that it is pressed tightly against the left side plate 102a, completing the second precise positioning and ensuring that the dental floss boxes are arranged neatly.

[0071] The palletizing conveyor belt 301 transports the inspected and positioned dental floss boxes to the palletizing area. The palletizing mechanism 500 starts working. The active motor 514 drives the active gear 515 to rotate along the active gear plate 516, which in turn moves the connecting plate 509 and the entire transverse moving assembly along the transverse slide plate 507. The auxiliary motor 518 drives the auxiliary gear 519 to rotate along the auxiliary gear plate 520, which in turn moves the auxiliary longitudinal rod 512 and the processing composite plate 521 up and down along the longitudinal limit block 510. Through the coordinated movement of the active motor 514 and the auxiliary motor 518, the palletizing suction cups 522 at the bottom of the processing composite plate 521 move precisely to the top of the dental floss box assembly to be picked up. The palletizing suction cups 522 are arranged in a matrix of four columns of five, for a total of twenty suction cups. At the same time, they pick up the twenty dental floss boxes required for one layer in the box. The vacuum generator is activated, the suction cups pick up the dental floss boxes, and then the active motor 514 and the auxiliary motor 518 move together to pick up the dental floss boxes. The auxiliary motor 518 drives the suction cup and dental floss box to the corresponding position inside the palletizing box 503, cuts off the vacuum, and the dental floss box falls neatly into the palletizing box 503. During the palletizing process, the stabilizing mechanism works synchronously. The stabilizing motor 501f drives the shaft 501d to rotate through the transmission belt, causing the two stabilizing plates 501e to swing and abut against the opening of the palletizing box 503 from both sides to prevent the opening from blocking the palletizing of the dental floss box. At the same time, the third clamping plate cylinders 502a-2 at the front and back ends of the palletizing box conveyor belt 502a drive the third clamping plate 502a-3 to extend and clamp the palletizing box 503, further ensuring the stability of the box. The suction, movement, and release actions are repeated until the palletizing box 503 is completely filled. After it is full, the third clamping plate 502a-3 is released, and the palletizing box conveyor belt 502a moves step by step to send the next empty palletizing box 503 into the working position. Full boxes are then removed manually.
