Description

Technical Field

[0001] The invention relates to the technical field of fresh-keeping sealing ring installation, in particular to an automatic sealing ring installation device for producing fresh-keeping boxes. Background Art

[0002] A fresh-keeping box is a container used to store food for the purpose of keeping it fresh and extending the storage time of food. It is widely used in daily life. It is a sealed container made of plastic, glass, ceramic and other materials. It is mainly used to store various foods, such as vegetables, fruits, meat, fresh agricultural products, etc. It can effectively maintain the freshness of food and prevent odor contamination. It is also easy to carry and store, meeting people's daily food storage and dining needs.

[0003] The sealing performance of a fresh-keeping box depends largely on the installation quality of the sealing ring. The sealing ring is tightly embedded in the sealing groove of the fresh-keeping box to form a reliable barrier to prevent the entry and exit of air, moisture and odor, thereby achieving the preservation function. With the growing market demand for fresh-keeping boxes, higher requirements are also placed on their production efficiency and quality. During the production process, automatic installation equipment is required to install the sealing ring in the fresh-keeping box.

[0004] The prior art publication number is CN112372267B, which provides an automatic installation device for sealing rings for producing fresh-keeping boxes, including: a stepping conveyor, a first limiting column is arranged on the conveying surface of which; a duplex reciprocating material moving mechanism, which is arranged on the top of the stepping conveyor; a first expansion and pressing mechanism and a second expansion and pressing mechanism, the expansion and pressing mechanisms are arranged at the working ends on both sides of the duplex reciprocating material moving mechanism, an expansion column is arranged at the bottom of the working end of the first expansion and pressing mechanism, and a first pressing ring is also arranged at the bottom of the working end of the first expansion and pressing mechanism; a first presenting mechanism and a second presenting mechanism, the presenting mechanisms are arranged on both sides of the stepping conveyor, the working end of the first presenting mechanism is provided with a presenting plate with a vertical axis for placing the sealing ring, the presenting plate is provided with an avoidance groove, and the top of the presenting plate is also provided with a second limiting column; a clamping mechanism, which is arranged on the top of the stepping conveyor, and the device can automatically press the sealing ring with high work efficiency.

[0005] The above-mentioned existing technology completes the pressing step by pressing a circular sealing ring into the fresh-keeping box lid. However, in order to achieve better sealing performance, the existing rectangular fresh-keeping box lid adopts a matching rectangular sealing ring. Compared with the circular sealing ring, the rectangular sealing ring has four protrusions. Therefore, compared with the circular sealing ring, more attention should be paid to the positioning problem. Because once the rectangular sealing ring is positioned incorrectly, the four protrusions cannot match the rectangular fresh-keeping box. Even if it is installed, it is very easy to fall off later. The existing production process uses a later manual quality inspection method to pick out the fresh-keeping boxes with fallen sealing rings. However, this quality inspection time is likely to prolong the production cycle and waste manpower.

[0006] It can be seen that there is a need for an automatic installation device for sealing rings in the production of fresh-keeping boxes to solve the problem that the existing devices mentioned in the above background technology do not have a mechanism for positioning the rectangular sealing ring, and lack a structure for loading the fresh-keeping box cover when the rectangular sealing ring is positioned incorrectly, so as to avoid assembly errors.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-6 A sealing ring automatic installation device for producing fresh-keeping boxes includes a support ring assembly 1, a correction assembly 2 for correcting a rectangular sealing ring is installed on one side of the support ring assembly 1, and four groups of retractable movable card plates 202 are installed at the bottom end of the correction assembly 2, a weight detection unit 201 is arranged below the mobile card plates 202, and a rotatable and downward pressing ring assembly 4 is arranged above the support ring assembly 1, the correction assembly 2, and the distance adjustment assembly 3.

[0025] In this embodiment, a controller is installed in the device, and the controller is electrically connected to the electronic components in the device to facilitate centralized control. In this device, the support ring assembly 1, the correction assembly 2 and the distance adjustment assembly 3 are all arranged below the pressure ring assembly 4. The position of the support ring member 411 for rotation and lifting matches the position of the support ring assembly 1, the correction assembly 2 and the distance adjustment assembly 3. In the support ring assembly 1, since the sealing ring to be opened is a rectangular structure, a support frame matching its shape is used to open the sealing ring. The number of sealing rings is multiple and is arranged at intervals on the support frame. A lifting device such as a cylinder can be installed at the bottom end of the support ring assembly 1 to raise the height of the sealing ring. After the support ring member 411 removes the top group of sealing rings, the cylinder below can lift the remaining sealing rings collectively to facilitate the next grabbing of the support ring member 411. The support frame for placing the sealing ring can also adopt a movable structure to facilitate handling of sealing rings of different sizes. A through groove is provided on the inner side of the support frame, which matches the through groove and the support ring member 411. The through groove can contact the sealing ring on the outside of the support frame to grab it.

[0026] Specifically, the correction component 2 includes a top plate and support legs, and the support legs are located at the four corners of the bottom of the top plate. A through hole is opened on the top plate to facilitate the passage of the sealing ring. The movable card plate 202 is located below the through hole. The four groups of movable card plates 202 are distributed in a rectangular shape, and the rear sides of the four groups of movable card plates 202 are all installed with telescopic rods, and the movable card plates 202 are in contact with the sealing ring.

[0027] In this embodiment, although the four groups of movable card plates 202 are rectangular in structure and distributed on the outside of the sealing ring, there are gaps between them and they are not connected end to end, because the four points where the rectangular lines are connected end to end are the positions of the four protrusions of the sealing ring in the correct position, so this position must be reserved. When the support ring member 411 brings the sealing ring down into the inside of the movable card plate 202, the activated telescopic rod will drive the movable card plate 202 close to the sealing ring. If the position of the protrusion is not in the reserved position, it means that the position of the sealing ring on the support ring member 411 is incorrect, and the movable card plate 202 will contact the protrusion. Therefore, when the support ring member 411 rises, the movable card plate 202 will pull the sealing ring down through the protrusion. , so that it falls on the weight detection unit 201, the weight detection unit 201 sends a signal to the controller, and the controller controls the telescopic rod 715 to start. At this time, since the sealing ring has fallen on the weight detection unit 201, there is no sealing ring on the support ring member 411. In the subsequent process of sleeved on the support ring rod 310, there is actually no sealing ring. Therefore, the dividing component 7 that cooperates with it will skip the fresh-keeping box cover, so that no fresh-keeping box cover with assembly errors is produced in this process. In this embodiment, the telescopic rod located on the rear side of the movable card plate 202 can be an electric telescopic rod, which is fixed by the top plate in the correction component 2. The weight detection unit 201 can be a weighing sensor or an electronic scale and other equipment.

[0028] Specifically, the pressing ring assembly 4 includes a pressing ring motor 401, and the output end of the pressing ring motor 401 is connected to a pulley group 402, one side of the pulley group 402 is connected to a rotating disk 403, and a shift block 4031 and a shift shaft 4032 are provided on the outer side of the rotating disk 403, the shift block 4031 and the shift shaft 4032 are in a cross structure, a rotating drum 404 is provided on one side of the rotating disk 403, and notch grooves 4041 are equidistantly provided at the top and bottom ends of the rotating drum 404, and oblique grooves 4042 are equidistantly provided on the body of the rotating drum 404, and the oblique grooves 4042 are in contact with the shift shaft 4032, and the notch grooves 4041 are in contact with the shift block 4031.

[0029] In this embodiment, support plates are provided below the pressing ring motor 401 and at the bottom end of the fixed block 408, which are connected to the ground to provide support for the installation of the fixed block 408 and the pressing ring motor 401. The pressing ring motor 401 can be a reduction motor. When started, it will drive the rotating disk 403 and the rotating rod 405 to rotate through the pulley group 402. The pulley group 402 includes a group of large pulleys, a group of small pulleys and a belt wrapped around the outside thereof. The large pulley is located at the rear side of the rotating disk 403, and the small pulley is located at the rear side of the rotating rod 405. There are two groups of shift blocks 4031 and shift shafts 4032 in the rotating disk 403, distributed on the rotating disk. The outer side of the turntable 403 is in a cross-shaped structure. As the rotating disk 403 rotates, it intermittently contacts the rotating drum 404. The setting angles of the notches 4041 set at the top and bottom of the rotating drum 404 are determined by the placement positions of the support ring assembly 1, the correction assembly 2, and the distance adjustment assembly 3 below. The inclined grooves 4042 staggeredly connect the notches 4041 set up above and below, so as the dial shaft 4032 rotates, the rotating drum 404 can be dialed to rotate a certain angle, and then the dial block 4031 enters the corresponding notch 4041. The dial block 4031 will not dial the rotating drum 404 to rotate, but will make the rotating drum 404 temporarily maintain the rotation angle after rotation.

[0030] Specifically, the interior of the rotating drum 404 passes through the lifting shaft 409, and the top of the lifting shaft 409 is connected to the lifting block 407, the lifting block 407 is located above the rotating drum 404, and the top of the lifting block 407 is connected to the arc block 406, the rear side of the arc block 406 is provided with a rotating rod 405, and a short pin shaft is provided on one side of the rotating rod 405, the short pin shaft is located inside the rotating rod 405 and moves, and the rotating rod 405 is located on one side of the pulley group 402.

[0031] In this embodiment, a limiting groove is provided inside the arc block 406, and the short pin shaft on one side of the rotating rod 405 passes through the limiting groove and extends to its outside, and the arc block 406 is limited in the fixed block 408 by the lifting block 407. Therefore, as the rotating rod 405 rotates, the arc block 406 and the lifting block 407 will be driven to perform lifting movements inside the fixed block 408. The lifting and lowering of the lifting block 407 will drive the lifting shaft 409, the rotating shaft 410 and the support ring part 411 to rise and fall, and in conjunction with the intermittent rotation of the rotating drum 404, the support ring part 411 will be driven to perform lifting and rotation movements.

[0032] Specifically, a fixed block 408 is provided on the outside of the lifting block 407, and the lifting block 407 is lifted and lowered inside the fixed block 408. The bottom end of the lifting shaft 409 is connected to the rotating shaft 410, and the bottom end of the rotating shaft 410 is connected to the support ring part 411, which supports the sealing ring and transports it.

[0033] In this embodiment, the support ring member 411 is a four-corner structure, which can be matched with a rectangular sealing ring. Four groups of support rods are arranged under the support ring member 411. The four groups of support rods can adopt an adjustable structure, so that it is convenient to deal with rectangular sealing rings of different sizes, and it is also convenient to expand when entering the interior of the support ring assembly 1 to support the sealing ring. The sealing ring is not in the correct position on the outside of the support ring member 411. It may be because it is offset when it is sleeved in the support ring assembly 1. Therefore, when the support ring member 411 stretches the offset sealing ring, the position is naturally incorrect, so it needs to be corrected by the correction assembly 2.

[0034] See also Figure 7-Figure 8 , an automatic sealing ring installation device for producing fresh-keeping boxes, a distance adjustment component 3 for pressing the sealing ring and the fresh-keeping box cover is provided on one side of the correction component 2, and the distance adjustment component 3 includes four groups of support ring rods 310 that can move synchronously.

[0035] In this embodiment, the pitch-adjustable motor 302 can be a reduction motor. After starting, it will drive the worm 303 to rotate, and the worm 303 will drive the worm wheel 304 engaged with it to rotate. The worm wheel 304 and the worm 303 form an anti-reversal structure. After the four groups of support ring rods 310 are positioned, even if a rubber ring is installed on the outside, the support ring rods 310 will not be displaced under force.

[0036] Specifically, the pitch-adjusting assembly 3 includes a mounting chamber 301, and a pitch-adjusting motor 302 is installed inside the mounting chamber 301, the output end of the pitch-adjusting motor 302 is connected to a worm 303, and a worm gear 304 is engaged on one side of the worm 303, a shaft is connected at the middle position of the worm gear 304, and the shaft is connected to a central gear 305, and four sets of side gears 306 are engaged on the outer side of the central gear 305, and the tops of the four sets of side gears 306 are all connected to a protrusion 307, a rectangular frame 308 is provided on the outer side of the protrusion 307, and a connecting shaft 309 is connected to the rear side of the rectangular frame 308, the outer side of the connecting shaft 309 is connected to a fixing plate through a sleeve block, and the fixing plate is connected to the mounting chamber 301, and a support ring rod 310 is connected above the end of the connecting shaft 309, the support ring rod 310 passes through the mounting chamber 301 and extends to its outer side, and the support ring rod 310 is connected to the sealing ring.

[0037] In this embodiment, a limiting groove is provided on the outside of the installation bin 301, and four groups of support ring rods 310 pass through the limiting groove and extend to the outside thereof. The four groups of support ring rods 310 can move synchronously, thereby expanding or reducing the distance between each other, and can flexibly cope with sealing rings of different sizes. After the support ring member 411 transports the sealing ring to the support ring rod 310 and stretches it, the support ring rod 310 will serve as a temporary placement point waiting for the cover of the fresh-keeping box. When the fresh-keeping box cover comes to the top of the distance-adjusting component 3, it will press down to make the sealing ring enter the internal card slot of the fresh-keeping box cover, and then the fresh-keeping box cover is transported by the grabbing block 611. A receiving barrel can be placed between the distance-adjusting component 3 and the transport bed 5. When the grabbing block 611 returns, the grabbed fresh-keeping box cover can be loosened to make it fall into the inside of the receiving barrel, completing an assembly.

[0038] See also Figures 9-13, an automatic sealing ring installation device for producing fresh-keeping boxes, a transport bed 5 for transporting fresh-keeping box lids is installed on one side of the distance adjustment component 3, a pressure cover component 6 is installed on one side of one end of the transport bed 5, and the pressure cover component 6 is used to transport the fresh-keeping box lid back and forth between the transport bed 5 and the distance adjustment component 3, a distributing component 7 for rotating the fresh-keeping box lid is provided on one side above the transport bed 5, the distributing component 7 includes a distributing motor 714, and a telescopic rod 715 is installed on the top of the distributing motor 714, the telescopic rod 715 is electrically connected to the weight detection unit 201, and the bottom end of the distributing motor 714 is connected to the cage pin 713 and the cage gear 712 It is connected to a crank 711, and one end of the crank 711 is hinged to a threaded rod 709 through a hinge shaft 710, and a rotating gear 707 is provided on the outside of the threaded sleeve 708 through which the threaded rod 709 passes, and the rotating gear 707 is provided at the bottom end of the movable plate 702 and meshed with it. A symmetrical first slope block 703 and a second slope block 704 are also provided on one side of the bottom end of the movable plate 702, and the bottom ends of the first slope block 703 and the second slope block 704 are respectively connected to a second distributing fork 706 and a first distributing fork 705 of the same structure, and the first distributing fork 705 and the second distributing fork 706 are dropped at intervals and contact the fresh-keeping box cover.

[0039] In this embodiment, the fresh-keeping box lid to be processed is placed on the transport bed 5, and the box lid is stably placed on the transport bed 5 and transported by the transport bed 5. The width of the transport bed 5 can be of a size that matches the box lid, so that the box lid can be transported by the transport bed 5 with a limit. In addition, a limiting mechanism can be installed on the transport bed 5 so that the box lid can be kept in the correct position when being transported on the transport bed 5. A grabbing block 611 is provided above one end of the transport bed 5. The grabbing block 611 moves back and forth between the transport bed 5 and the distance-adjusting component 3, grabbing the box lid transported on the transport bed 5 and then transporting it to the distance-adjusting component 3. During the process, due to the existence of the dividing component 7, the box covers are moved one by one from the bottom of the dividing component 7 to one end of the transport bed 5. The second dividing fork 706 and the first dividing fork 705 that descend alternately not only play the role of dividing the materials, but also create a time difference. Only after the previous group of box covers are grabbed by the grabbing block 611 will the box covers move to one end of the transport bed 5, avoiding the accumulation of box covers at one end of the transport bed 5. After starting the telescopic rod 715, the process of alternating descent between the first dividing fork 705 and the second dividing fork 706 is suspended, so the box covers will not move from the bottom of the dividing component 7 to one end of the transport bed 5, thereby achieving a bye.

[0041] In this embodiment, the capping motor 601 can be a reduction motor. After starting, it will drive the first large gear 603 to rotate, and the first large gear 603 drives the second large gear 604 meshing with it to rotate, and the fixing frame 602 is on the rear side of the first large gear 603 and the second large gear 604 to provide support for them. The fixing frame 602 includes a cross rod and a cross rod. The horizontal axis of the cross rod is connected to the vertical axis. The cross axis is located on the rear side of the first large gear 603 and the second large gear 604, and a support plate is provided on the rear side of the cross axis, which is located at the bottom end of the capping motor 601. To provide support for it, a rotating shaft is provided at the top of the longitudinal axis and is hinged to the cross bar 606, and the bottom end of the longitudinal axis is connected to the support block. One end of the cross bar at the top of the cross bar is hinged to the tilting rod 610. The lifting limit slot 6031 and the second large gear 604 are different in shape. The lifting limit slot 6031 is shaped like an apple and is mainly lifted and lowered by rotating the lifting rod 605, while the displacement limit slot 6041 is fan-shaped. Its main function is to limit the tilting rod 610, so that it drives the displacement rod 609 and the material picking rod 608 to move back and forth. The two work together to enable the grabbing block 611 to complete the actions of grabbing the box cover, transporting the box cover, and pressing the sealing strip.

[0042] Specifically, a first pin 6081 is provided inside the limit block 607, and the first pin 6081 is provided at the top end of the material picking rod 608, the bottom end of the material picking rod 608 is connected to the grabbing block 611, and the outer side of the material picking rod 608 is sleeved with a sleeve block 6091, one side of the sleeve block 6091 is connected to the displacement rod 609, and the end of the displacement rod 609 away from the sleeve block 6091 is connected to the second pin 6092, the second pin 6092 is located inside the waist hole groove 6101, the waist hole groove 6101 is provided at the bottom end of the tilting rod 610, and the middle part of the tilting rod 610 is connected to the second hinge block 6102, the second hinge block 6102 is located inside the displacement limit groove 6041 and moves, and the top of the tilting rod 610 is hinged to the fixed frame 602.

[0043] In this embodiment, the lifting and lowering of the lifting rod 605 will drive the limit block 607 to rise and fall through the cross bar 606, and then drive the entire material picking rod 608 to rise and fall through the first pin shaft 6081, and the sleeve block 6091 is sleeved on the outside of the material picking rod 608. When the material picking rod 608 is raised and lowered, it does not affect the sleeve block 6091, but when the sleeve block 6091 is driven by the displacement rod 609 to move horizontally, it will drive the material picking rod 608 to move horizontally. The grabbing block 611 can be a suction cup structure, which uses negative pressure to absorb and grab the box cover.

[0044] Specifically, the material distribution component 7 includes a mounting frame 701, and the mounting frame 701 is arranged on the outside of the movable plate 702, one end of the movable plate 702 is connected to the fixed plate, and the movable plate 702 slides on the bottom end of the fixed plate, one side of the bottom end of the movable plate 702 is connected to the teeth 7021, and the teeth 7021 are engaged with the rotating gear 707, the interior of the threaded sleeve 708 is provided with a threaded hole matching the threaded rod 709, and the outside of the threaded sleeve 708 is provided with a bearing and a support frame, the threaded rod 709 passes through the threaded sleeve 708 and moves in and out thereof, and the rear side of one end of the hinge shaft 710 is hinged with a crank 711, the rear side of the crank 711 is connected to a cage gear 712, and a cage pin 713 matching it is provided above the cage gear 712.

[0045] The gear 712 is rotated by the pinion 714 and the pinion 715 is rotated by the pinion 716. The gear 712 is rotated by the pinion 717 and the pinion 718 is rotated by the pinion 719.

[0046] Specifically, the bottom ends of the first slope block 703 and the second slope block 704 are both provided with sloped surfaces, and the first slope block 703 and the second slope block 704 are staggered front and back, and the sloped surfaces at the bottom ends of the first slope block 703 and the second slope block 704 are mirror-imaged, and the top end of the first material dividing fork 705 is connected to a roller 7051, and the roller 7051 rolls on the sloped surface of the second slope block 704, the bottom end of the roller 7051 is connected to the shaft, and the bottom end of the shaft is connected to a collection rack 7052, and the bottom end of the collection rack 7052 is connected to a material blocking fork 7053, and the roller at the top end of the second material dividing fork 706 rolls on the sloped surface at the bottom of the first slope block 703.

[0047] In this embodiment, the threaded rod 709 moves inside the threaded sleeve 708, and drives the threaded sleeve 708 to rotate through the threaded relationship. The rotation of the threaded sleeve 708 drives the rotating gear 707 to rotate, thereby driving the movable plate 702 to move horizontally inside the mounting frame 701. The horizontal movement of the movable plate 702 drives the positions of the first slope block 703 and the second slope block 704 to change, so that the slope facing the top of the second distributing fork 706 and the first distributing fork 705 changes, and then the second distributing fork 706 and the first distributing fork 705 will alternately descend. The shafts of the first distributing fork 705 and the second distributing fork 706 both pass through the mounting frame 7 01, and the spring arranged on the outside of the shaft helps it to reset after it falls. When the first material-dividing fork 705 and the second material-dividing fork 706 fall, they will block the movement of the box cover through the blocking fork. When the first material-dividing fork 705 falls, the second material-dividing fork 706 rises, and the first material-dividing fork 705 blocks the movement of the box cover through the blocking fork. When the first material-dividing fork 705 rises, the blocked box cover is moved for transportation. At this time, the second material-dividing fork 706 falls to block the next group of box covers, and waits for the previous group of box covers to be grabbed and transported by the grabbing block 611 before it rises. The second material-dividing fork 706 and the first material-dividing fork 705 are separated by the distance of a box cover.

[0048] When in use, first start the ring pressing motor 401, so that the ring pressing motor 401 drives the pulley group 402 to rotate, and the rotating disk 403 located on one side of the pulley group 402 will also rotate. The rotation of the rotating disk 403 will drive the dial block 4031 and the dial shaft 4032 to rotate, and the dial shaft 4032 enters the corresponding inclined groove 4042 and drives the rotating drum 404 to rotate as a whole according to the inclined trajectory set by the inclined groove 4042. The dial block 4031 enters the corresponding notch groove 4041 to play a certain stopping purpose, so that the rotating drum 404 rotates intermittently, and the rotation of the rotating drum 404 will drive the lifting shaft 409 to rotate, thereby driving the rotating shaft 410 and the support ring member 411 The pulley assembly 402 not only drives the rotating disk 403 to rotate, but also drives the rotating rod 405 to rotate. The rotation of the rotating rod 405 drives the arc block 406 and the lifting block 407 to rise and fall on the inner side of the fixed block 408. The lifting of the lifting block 407 also drives the lifting shaft 409 to rise and fall. Therefore, the lifting shaft 409 drives the support ring member 411 to perform the lifting action and rotate at the same time, so that the support ring member 411 descends to open the rectangular sealing ring on the support ring assembly 1 and then rises. When it rotates to the top of the correction assembly 2 station, it descends, then rises again, rotates to the top of the distance adjustment assembly 3 station, then descends again, and then repeats the above action. When the support ring member 411 descends at the position of the correction component 2, the support ring member 411 including the rectangular sealing ring it carries first passes through the correction component 2 and enters the center position of the movable card plate 202. The movable card plates 202 on the four sides move closer to the sealing ring under the action of the telescopic rods. If the sealing ring is in the correct position, the four convex points of the rectangle will be at the contact points between the support ring member 411 and the sealing ring, so the approaching movable card plate 202 cannot touch it. The rising support ring member 411 rotates with the stretched sealing ring to the position of the distance adjustment component 3. When descending, the sealing ring is sleeved on the four groups of support ring rods 310, waiting for the fresh-keeping box cover to be loaded and covered; The fresh-keeping box cover is transported on the transport bed 5, and the started feeding motor 714 will drive the cage gear 712 to rotate through the cage pin 713, and the cage gear 712 will drive the hinge shaft 710 to rotate through the crank 711, thereby driving the threaded rod 709 to move in and out of the threaded sleeve 708. The threaded sleeve 708 will rotate forward and reverse when being penetrated by the threaded rod 709, thereby driving the rotating gear 707 to rotate forward and reverse, and the rotating gear 707 rotates through the teeth 7021 to drive the moving plate 7 02 moves back and forth, and the movement of the moving plate 702 will drive the first slope block 703 and the second slope block 704 to move together. The roller parts on the top of the first distributing fork 705 and the second distributing fork 706 will contact the slope position, so the first distributing fork 705 and the second distributing fork 706 positioned by the mounting frame 701 will perform alternating lifting and lowering actions in situ. The first distributing fork 705 and the second distributing fork 706 are separated by a fresh-keeping box cover. Alternating lifting and lowering can move the fresh-keeping box covers one by one to the transport bed 5, that is, below the grab block 611, start the capping motor 601, so that the capping motor 601 drives the first large gear 603 to rotate, and the first large gear 603 drives the second large gear 604 to rotate through engagement. When the first large gear 603 rotates, it will drive the lifting rod 605 to move up and down due to the limiting relationship of the lifting limit groove 6031. The lifting rod 605 drives the cross bar 606 and the limit block 607 to move up and down, and the limit block 607 will drive the material picking rod 608 to move up and down, and as the second large gear 60 4 rotates, the second hinge block 6102 limited in the displacement limiting groove 6041 will drive the tilting rod 610 to tilt as a whole, and the waist hole groove 6101 will drive the picking rod 608 to move back and forth through the displacement rod 609, so that the picking rod 608 will descend at one end of the transport bed 5, grab the fresh-keeping box lid, and then move it up to the position of the distance adjustment component 3 and descend, so that the fresh-keeping box lid is covered on the sealing ring, and then the assembled fresh-keeping box lid is driven to move to the transport bed 5 to unload the material, and finally return to the top of the transport bed 5 to wait for the next transportation; If the rectangular sealing ring is not placed in the correct position on the support ring part 411, the four protrusions will be located on the side of the support ring part 411. At this time, the moving card plate 202 that is close to the protrusions will come into contact with the protrusions. When the support ring part 411 drives the sealing ring to rise, the sealing ring will be pulled down and fall onto the weight detection unit 201. The weight detection unit 201 will control the telescopic rod 715 to start, and the telescopic rod 715 will drive the material distribution motor 714 and the cage pin 713 to rise, so that the cage pin 713 will not come into contact with the cage gear 712, and the rotation with the cage gear 712 will be disconnected. The rotation connection makes it impossible for the cage gear 712 to drive the threaded sleeve 708 to rotate through the crank 711, the hinge shaft 710 and the threaded rod 709, and the movable plate 702 cannot move back and forth, and the second material distribution fork 706 and the first material distribution fork 705 cannot be driven to rise and fall alternately through the first ramp block 703 and the second ramp block 704. The sealed box cover transported on the transport bed 5 will be blocked and cannot move to the bottom of the grab block 611. Even if the grab block 611 moves, it cannot grab the sealed box cover and transport it to the distance adjustment component 3 station, thereby achieving a bye to avoid incorrect assembly.
