DETAILED DESCRIPTION

[0045] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] refer to Figure 2-9 , showing a device for recycling pallets, comprising:

[0047] The third conveying roller 38 is located between the paper feeding section 7 and the paper receiving section 4. The third conveying roller 38 is used to connect the paper feeding table roller 9 and the paper receiving table roller 43 and transport the empty tray 2 from the position of the paper feeding table roller 9 to the position of the paper receiving table roller 43;

[0048] A paper feed tray pushing mechanism, which is installed at the position of the paper feed unit sleeve 7 and is located on the transmission side of the paper feed table roller 9, and is used to push the empty tray 2 after the printed paper 8 is transported from the paper feed table roller 9 to the third transport roller 38;

[0049] The paper collection tray pushing mechanism is installed at the position of the paper collection section 4 and is located on the operating side of the paper collection table roller 43. The paper collection tray pushing mechanism is used to push the empty tray 2 conveyed from the paper feeding section 7 from the third conveying roller 38 to the paper collection table roller 43.

[0050] The utility model pushes the empty pallet 2 from the paper feed table roller of the paper feed section 7 to the third conveying roller 38 through the paper feed tray pushing mechanism, and the third conveying roller 38 conveys the empty pallet 2 to the paper collection section 4, and then pushes the empty pallet 2 to the paper collection table roller 43 through the paper collection tray pushing mechanism, thereby realizing the transportation of the empty pallet 2 between the paper feed section 7 and the paper collection section 4, eliminating the process of manual handling.

[0051] Preferably, reference Figure 2The upstream of the paper conveyor roller 9 is also provided with a first conveying roller 28 and a second conveying roller 27, and the second conveying roller 27 is connected with the paper conveyor roller. The first conveying roller 28 and the second conveying roller 27 are connected through a first rotating roller 26; the first tray baffles 29 are provided on both sides of the second conveying roller 27 along the conveying direction. It can be understood that the tray 2 with the printed paper 8 is placed on the first conveying roller 28 by a logistics transportation tool (including but not limited to a forklift, a shovel or a logistics roller, etc.), and the first conveying roller 28 can be rotated under the drive of an independent power system to convey the tray 2 to the first rotating roller 26. The first rotating roller 26 adjusts the direction of the tray 2 according to the paper feeding direction of the second conveying roller 27. When the direction is adjusted to be consistent with the paper feeding direction of the second conveying roller 27, the second conveying roller 27 conveys the tray 2 to the second conveying roller 27 under the drive of an independent power system (if the paper feeding directions of the first conveying roller 28 and the second conveying roller 27 are the same, the first rotating roller 26 is not required, and the second conveying roller 27 then conveys the tray to the paper feeding table roller 9 installed on the paper feeding table 10 of the paper feeding part sleeve 7, and the paper feeding table roller 9 is rotated with the paper feeding table roller 9. Driven by the paper feeder platen driving mechanism 12, the paper feeder platen 10 rises until the printed paper 8 on the tray 2 contacts the paper feeder head 11. The paper feeder head 11 conveys the topmost printed paper 8 in contact with it to the automatic paper feeder. The paper feeder platen driving mechanism 12 continues to drive the paper feeder platen 10 and the paper feeder roller 9 to rise, so that the paper feeder head 11 gradually conveys the printed paper 8 on the tray 2 to the automatic paper feeder. The printed paper 8 passes through the main machine sleeve 6 and the waste removal sleeve 5 with the automatic paper feeder in turn to become the finished paper 1, and is conveyed to the paper collection sleeve 4 by the automatic paper feeder. It should be noted that in order to prevent the position deviation of the tray 2 from being too large at the paper feeder roller 9 after being conveyed by the second conveying roller 27, it is preferred to provide a first tray baffle 29 on both sides of the second conveying roller 27 along the conveying direction to limit the position of the tray 2.

[0052] Preferably, reference Figure 3 , Figure 8 and Fig. 9The fourth conveying roller 46 and the fifth conveying roller 47 are connected to the downstream of the paper delivery platform roller 43, and the fourth conveying roller 46 is connected to the paper delivery platform roller 43. The fourth conveying roller 46 and the fifth conveying roller 47 are connected through the second rotating roller 3; the third tray baffle 54 is provided on both sides of the fourth conveying roller 46 along the conveying direction. Understandably, the empty tray conveyed from the paper feeding section 7 is pushed by the paper receiving tray pushing mechanism to the paper receiving table roller 43 installed on the paper receiving table 42 of the paper receiving section 4. The paper receiving table 42 and the paper receiving table roller 43 are driven by the paper receiving table driving mechanism to carry the empty tray up to the position for receiving the finished paper 1, collect and stack the finished paper 1. After the finished paper 1 reaches a certain number, the paper receiving table driving mechanism drives the paper receiving table 42 and the paper receiving table roller 43 to carry the tray 2 carrying the finished paper 1 down to the set position. The paper receiving table roller 43 rotates under the drive of the independent power system and conveys the tray 2 to the fourth conveying roller 46. The fourth conveying roller 46 continues to convey the tray to the second rotating roller 3 under the drive of the independent power system. After the second rotating roller 3 adjusts the tray to the paper feeding direction of the fifth conveying roller 47, it is driven by the independent power system to convey the tray to the fifth conveying roller 47 (if the paper feeding directions of the fourth conveying roller 46 and the fifth conveying roller 47 are opposite). At the same time, the second rotating roller 3 is not needed. The fifth conveying roller 47, driven by the independent power system, conveys the tray 2 carrying the finished paper 1 to the logistics transportation tool (including but not limited to a forklift, a forklift or a logistics roller, etc.), and finally transports the tray 2 and the finished paper 1 away. Preferably, a third tray baffle 54 is set on both sides of the fourth conveying roller 46 along the paper feeding direction to limit the conveying process of the tray. The independent power system in the utility model at least includes a motor, a rotating shaft and a driving wheel. The output end of the motor is connected to the rotating shaft, the driving wheel is installed on the rotating shaft, the driving wheel contacts the tray, the motor drives the rotating shaft to drive the driving wheel to rotate to realize the conveying of the tray, and the independent power system can also include a plurality of groups of slave rotating shafts and slave rotating wheels installed with the slave rotating shafts. The slave rotating wheels play a supporting role for the tray. When the tray moves under the rotation of the driving wheel, the driven wheel also rotates to minimize the friction when the tray moves. The independent power system drives each roller to rotate, which is a prior art and will not be repeated here.

[0053] In a specific implementation, the paper feed tray pushing mechanism includes a first-level pushing mechanism and a second-level pushing mechanism, and the second-level pushing mechanism is installed on the first-level pushing mechanism.

[0057] Preferably, reference Figure 2 The third conveying roller 38 is provided with a second pallet baffle 49 and a pallet positioning baffle 53; the second pallet baffle is arranged on both sides of the third conveying roller 38 along the paper feeding direction and on the upstream side of the third conveying roller 38 to limit the empty pallet 2 output from the paper feeding section 7 when being conveyed by the third conveying roller 38; the pallet positioning baffle 53 is arranged on the downstream side of the third conveying roller 38 to position the empty pallet 2 conveyed to the paper receiving section 4.

[0058] In a specific embodiment, reference Figure 4 and Figure 7 The device for recycling the tray also includes a non-stop paper feeding mechanism, which is installed upstream of the paper feeding sleeve 7 and close to the position of the paper feeding sleeve 7;

[0059] Preferably, the non-stop paper feeding mechanism comprises:

[0060] The non-stop paper feeding mechanism wall panel 25 includes a transmission side wall panel 30 located on the transmission side and an operation side wall panel 48 located on the operation side;

[0061] A transverse plate 13, which is located between the transmission side wall plate 30 and the operation side wall plate 48, and two ends of the transverse plate 13 are respectively connected to the transmission side wall plate 30 and the operation side wall plate 48;

[0062] The rod lifting frame 16 can be slidably mounted on the transmission side wall panel 30 and the operation side wall panel 48 through the rod lifting frame slide rail pair 15. The bottom of the rod lifting frame 16 is equipped with a rod frame moving rack 17 along the paper feeding direction, a slide rail 24 and a rod frame 19 perpendicular to the paper feeding direction. The rod frame moving rack 17 is located at the middle position of the bottom of the rod lifting frame 16. The slide rail 24 is located on the operation side and / or transmission side of the rod lifting frame 16. The rod frame 19 is slidably connected to the slide rail 24 through the slide rail seat 23. The rod frame 19 is used to install the non-parking rod 18;

[0063] The rod insertion driving motor 20 is fixedly mounted on the rod insertion frame 19 via a motor mounting plate 22, and the output shaft of the rod insertion driving motor 20 is connected to a rod insertion frame moving gear 21 that cooperates with the rod insertion frame moving rack 17;

[0064] The rod rack lifting drive assembly includes a rod rack lifting drive motor 14 and a bearing seat 57 installed on the horizontal plate 13. The bearing seat 57 is installed one on the operating side and the transmission side of the horizontal plate 13. A lifting drive shaft 58 is fixedly installed in the reduction box hole of the rod rack lifting drive motor 14. The two ends of the lifting drive shaft 58 are rotatably installed on the bearing seats 57 on the operating side and the transmission side respectively. The two ends of the lifting drive shaft 58 that extend beyond the bearing seat 57 are installed with rod rack lifting sprockets 55. The rod rack lifting sprockets 55 are connected to the rod rack lifting frame 16 through a rod rack lifting chain 56.

[0065] In this specific implementation manner, when the paper feed table driving mechanism 12 drives the paper feed table 10 and the paper feed table roller 9 to lift the tray 2 carrying the printed paper 8 to a set height (generally, the groove of the tray 2 is flush with the non-stop insertion rod 18), the insertion rod driving motor 20 drives the insertion rod frame moving gear 21 to move on the insertion rod frame moving rack 17 through the output shaft, so that the insertion rod frame moving gear 21 drives the insertion rod driving motor 20 to move, and then the insertion rod driving motor 20 drives the insertion rod frame 19 to move. When the insertion rod frame 19 moves, it drives the non-stop insertion rod 18 to move and insert it into the groove of the tray. At this time, the paper feed table driving mechanism 12 drives the paper feed table 10 and the paper feed table roller 9 to move downward with the tray 2, and the printed paper 8 is supported by the non-stop insertion rod 18, and the empty tray 2 is on the paper feed table driving mechanism 1 2, the paper feeding table 10 and the paper feeding table roller 9 continue to move downward to the set position to wait for the paper feeding tray pushing mechanism to push it to the third conveying roller 38; at the same time, the rod frame lifting drive motor 14 drives the rod frame lifting sprocket 55 to rotate through the lifting drive shaft 58, thereby driving the rod frame lifting frame 16 to rise through the rod frame lifting chain 56, so that the non-stop rod 18 continues to rise with the printed paper 8 so that the paper feeding head 11 continues to transport the printed paper 8. When the printed paper on the non-stop rod 18 is taken away by the paper feeding head 11, the non-stop rod 18 is retracted under the drive of the rod driving motor 20, and the rod lifting frame is driven by the rod plus lifting drive motor 14 to descend to the set position (the position flush with the groove of the tray 2) to enter the next cycle. It can be seen that the non-stop paper feeding mechanism in the utility model does not need to manually place the non-stop rod 18.

[0066] The utility model is achieved through the following measures:

[0071] The horizontal upper section of the rollers of each conveying roller conveyor is located in the same plane as the horizontal upper section of the rollers of the paper feeding platform roller conveyor 9 and the paper receiving platform roller conveyor 43.

[0072] In order to improve the automatic transfer efficiency of the tray 2, an external non-stop paper feeding mechanism is fixedly installed on the right side of the paper feeding unit sleeve 7 near the paper feeding unit sleeve 7. The transmission side wall plate 30 (25) and the operating side wall plate 48 (25) of the external non-stop paper feeding mechanism are respectively fixedly installed on both sides of the second conveying roller 27, and are flush with the transmission side and operating side wall plates of the paper feeding unit sleeve 7. A horizontal plate 13 is fixedly installed on the upper part between the transmission side wall plate 30 (25) and the operating side wall plate 48 (25), and a rod insertion frame lifting drive motor 14 is fixedly installed in the middle position of the upper surface of the horizontal plate 13. A lifting drive shaft 58 is fixedly installed in the reduction box hole of the rod insertion frame lifting drive motor 14, and the axis of the lifting drive shaft 58 is perpendicular to the paper feeding direction. A bearing seat 57 is fixedly installed at the symmetrical position of the upper surface of the horizontal plate 13 near the transmission side wall plate 30 (25) and the operating side wall plate 48 (25). The two ends of the lifting drive shaft 58 are supported and installed on two bearing seats 57. At the ends of the shafts of the lifting drive shaft 58 extending out of the bearing seats 57, there are symmetrically fixedly connected a rod insertion frame lifting sprocket 55, and two rod insertion frame lifting chains 56 are respectively passed around and supported on the two rod insertion frame lifting sprockets 55. One end of one of the rod insertion frame lifting chains 56 passes through a square hole on the horizontal plate 13 near the transmission side wall plate 30 (25) and is fixedly connected to one side of the rod insertion frame 16, and one end of the other rod insertion frame lifting chain 56 passes through a square hole on the horizontal plate 13 near the operating side wall plate 48 (25) and is fixedly connected to the other side of the rod insertion frame 16. The rod lifting frame 16 is located between the transmission side wall plate 30 (25) and the operating side wall plate 48 (25), and can slide up and down along the rod lifting frame slide rails 15 fixed to the transmission side wall plate 30 (25), the operating side wall plate 48 (25) and the transmission side and the operating side of the rod lifting frame 16. In the middle position of the lower part of the rod lifting frame 16, parallel to the paper feeding direction, a rod frame moving rack 17 is fixedly installed horizontally, and at the lower operating side and the transmission side of the rod lifting frame 16, slide rails 24 are fixedly installed at positions parallel to the rod frame moving rack 17. Two slide rail seats 23 are respectively installed on the slide rails 24 on the operating side and the transmission side, and the four slide rail seats 23 are fixedly connected to the lower surface of the rod frame 19, and the rod frame 19 can slide along the slide rails 24. A motor mounting plate 22 is fixedly connected to the lower surface of the middle part of the rod insertion frame 19, a rod insertion driving motor 20 is fixedly mounted on the motor mounting plate 22, a rod insertion frame moving gear 21 is fixedly mounted on the output shaft of the rod insertion driving motor 20, and the rod insertion frame moving gear 21 meshes with the rod insertion frame moving rack 17 to form a gear pair. On the upper surface of the rod insertion frame 19, a plurality of non-stop rods 18 are fixedly connected in parallel, and the spacing distance of the plurality of non-stop rods 18 is the same as the spacing of the grooves on the tray 2. The non-stop rods 18 can be inserted into the grooves on the tray 2.

[0073] When the paper feed platen driving mechanism 12 drives the paper feed tray 2 carrying the printed paper 8 to rise to a predetermined position close to the paper feed head 11, the rod driving motor 20 drives the rod frame moving gear 21 to rotate, and through the meshing of the rod frame moving gear 21 and the rack 17, the rod frame 19 is driven to slide along the slide rail 24 on the rod lifting frame 16 toward the paper feed sleeve 7, and a plurality of non-stop rods 18 are inserted into the grooves of the tray 2. As the paper feed head 11 continues to transport the printed paper 8 forward, the rod lifting frame driving motor 14 synchronously drives the lifting drive shaft 58 and the rod lifting sprocket 55 fixed at both ends to rotate, and lifts the rod lifting frame 16 upward through the two rod lifting chains 56 located on the transmission side and the operating side. The rod lifting frame 16 and the non-stop rods 18 hold the remaining printed paper 8 and continue to rise. At the same time, the paper feed platen driving mechanism 12 drives the paper feed platen 10 and the paper feed platen roller 9 fixedly installed on the paper feed platen 10 to descend. When the paper feed platen 10 and the paper feed platen roller 9 descend to the lowest position, the empty tray 2 supported on the paper feed platen roller 9 is pushed to the third conveying roller 38 by the second pushing plate 37 of the paper feed platen pushing mechanism. After the second pushing plate 37 returns to the initial position, the new tray 2 carrying the stacked printed paper 8 enters the paper feed section. At this time, the paper feed platen driving mechanism 12 drives the paper feed platen 10 and the paper feed platen roller 9 to continuously rise with the tray 2, so that when the upper plane of the printed paper 8 stacked on the tray 2 contacts the non-stop insertion rod 18, several non-stop insertion rods 18 are driven by the insertion rod driving motor 20 to return to the initial position. The paper feed platen driving mechanism 12 continues to drive the paper feed platen 10 and the paper feed platen roller 9 to carry the tray 2 and the stacked printed paper 8 upward. The paper feed enters a new cycle.

[0074] When working, (according to Figure 2 The logistics transportation tool (including but not limited to a forklift, a forklift or a logistics roller, etc.) transports the pallet 2 stacked with printed paper 8 to the first conveying roller 28, and the pallet 2 is transported to the first rotating roller 26 by the first conveying roller 28. After the first rotating roller 26 carries the pallet 2 and the stacked printed paper 8 and rotates 90 degrees, the printed paper 8 and the pallet 2 are transported to the second conveying roller 27. Under the transportation of the second conveying roller 27, the pallet 2 carrying the printed paper 8 is sent to the paper feed table roller 9 on the paper feed table 10 for positioning.

[0075] The paper feed table driving mechanism 12 drives the paper feed table 10 and the paper feed table roller 9 to lift up, and lift the upper surface of the printed paper 8 stacked on the tray 2 until it contacts the paper feed head 11. The paper feed head 11 transports the stacked printed paper 8 one by one to the automatic paper feed table and sends them to the printing press or the hot stamping and die-cutting machine. As the paper feed head 11 of the paper feed unit 7 continuously transports the printed paper forward, the paper feed table 10 and the paper feed table roller 9, driven by the paper feed table driving mechanism 12, continuously rise with the tray 2 and the stacked printed paper 8. When the paper feed tray 2 rises to a predetermined position close to the paper feed head 11, the insertion rod driving motor 20 drives the plurality of non-stop insertion rods 18 on the insertion rod lifting frame 16 to insert into the grooves of the tray 2. As the paper feed head 11 continues to transport the printed paper 8 forward, the rod lift frame driving motor 14 synchronously drives the rod lift frame 16 and the non-stop rod 18 to lift upward, and the non-stop rod 18 holds the remaining printed paper 8 to continue to rise. At the same time, the paper feed table driving mechanism 12 drives the paper feed table 10 and the paper feed table roller 9 fixedly installed on the paper feed table 10 to descend. When the paper feed table 10 and the paper feed table roller 9 descend to the lowest position, the push rod of the first tray push cylinder 32 and the first push plate 36 fixedly connected to the push rod are pushed forward, and at the same time, the push rod of the second tray push cylinder 34 fixedly installed on the first push plate 36 and the second push plate 37 fixedly connected to the push rod are also pushed forward, and the empty tray 2 supported on the paper feed table roller 9 is pushed from the paper feed table roller 9 to the third conveying roller 38 through the second push plate 37. After the push rods of the first tray push cylinder 32 and the second tray push cylinder 34 return to their initial positions, a new tray 2 carrying the stacked printed paper 8 enters the paper feed section. At this time, the paper feed table driving mechanism 12 drives the paper feed table 10 and the paper feed table roller 9 to continuously lift the tray 2, so that the upper surface of the printed paper 8 stacked on the tray 2 contacts the non-stop insertion rods 18, and the non-stop insertion rods 18 are driven by the insertion rod driving motor 20 to return to their initial positions. The paper feed table driving mechanism 12 continues to drive the paper feed table 10 and the paper feed table roller 9 to carry the tray 2 and the stacked printed paper 8 upward.

[0076] Driven by its independent power system, the third conveying roller 38 conveys the empty pallet 2 pushed onto the third conveying roller 38 to the leftmost side of the third conveying roller 38 and positions it on the pallet positioning baffle 53. After the pallet 2 is positioned, the paper receiving tray push motor 50 drives the left pallet push sprocket 45 and the right pallet push sprocket 40 to rotate, and pushes the empty pallet 2 positioned on the pallet positioning baffle 53 onto the paper receiving table roller 43 through two pallet push chains 39 supported and mounted on the left pallet push sprocket 45 and the right pallet push sprocket 40 and the pallet push plate 41 fixedly mounted on the pallet push chain 39. After the empty pallet 2 is pushed onto the paper receiving table roller 43, the paper receiving tray push motor 50 rotates in the opposite direction, causing the pallet push plate 41 to return to its original position. The paper receiving table drive mechanism drives the paper receiving table 42 and the paper receiving table roller 43 to carry the empty pallet 2 to the position of receiving the finished paper 1, and starts to collect and stack the finished paper 1 after processing. When the number of finished paper sheets 1 stacked on the tray 2 reaches a certain amount, the delivery tray driving mechanism drives the delivery tray 42 and the delivery tray roller 43 to carry the tray 2 and the stacked finished paper sheets 1 down to the lowest position, and driven by an independent power system, the tray 2 and the stacked finished paper sheets 1 are transported to the fourth conveying roller 46. Afterwards, a new empty tray 2 can be transported to the delivery tray roller 43 of the delivery tray 42, entering a new cycle.

[0077] according to Figure 2 In the arrangement of the fourth conveying roller 46, the second rotating roller 3 and the fifth conveying roller 47, driven by the independent power system of the fourth conveying roller 46, the tray 2 carrying the finished paper 1 on the fourth conveying roller 46 is conveyed to the second rotating roller 3. After the second rotating roller 3 carrying the tray 2 and the stacked finished paper 1 rotates 90°, the finished paper 1 and the tray 2 are conveyed to the fifth conveying roller 47. After that, the tray 2 and the stacked finished paper 1 can be transported away by logistics transportation tools (including but not limited to forklifts, forklifts or logistics rollers, etc.).
