Description

Technical Field

[0001] The utility model relates to post-printing mechanical equipment, in particular to a corrugated paper turning and loading machine with a telescopic baffle. Background Art

[0002] Single corrugated paper printing slotting machine ( Figure 1A ) or automatic die cutting machine ( Figure 1B ) are equipped with an automatic corrugated paper feeding unit. When working, it is necessary to manually place the corrugated cardboard on the stacking table of the automatic corrugated paper feeding unit, or use a flat push automatic paper loader and a flip paper loader to replace manual feeding of the corrugated cardboard on the stacking table of the automatic paper feeding unit. When the corrugated cardboard to be processed needs to be flipped before processing, a flip paper loader is generally used.

[0003] The corrugated paper pile is transported to the paper feed table by the corrugated paper conveyor line and positioned at the front positioning baffle. After that, the paper feed table crossbar, driven by the paper feed table driving mechanism, drives the paper feed table to lift the corrugated paper pile to a certain height by using the paper feed table slide rail, and flips it together with the flip frame. When the flip frame flips to its flip limit position, the paper surface of the corrugated paper pile forms an acute angle with the corrugated paper feed table. At this time, the paper feed table continues to move under the drive of the paper feed table driving mechanism, and gradually pushes the corrugated paper pile onto the paper feed belt of the corrugated paper feed table. As the paper feed belt of the corrugated paper feed table moves forward, the corrugated paper on the corrugated paper feed table can be sent to the position of the paper feed part of the printing slotting machine or the automatic die-cutting machine in the shape of fish scales. After the paper feed table pushes all the corrugated paperboards into the corrugated paper feed table, the paper feed table falls back to the initial position, and the flip frame rotates in the opposite direction and returns to the initial position. Figure 2 The schematic diagram of the paper loading of the paper loading machine of the single corrugated paper printing automatic die-cutting machine in the prior art is shown. It can be seen from the paper loading method of the paper loading machine in the prior art that only when the previous pile of corrugated paper is delivered, the turning frame can be turned over and restored to the state of waiting for paper loading, and the paper loading efficiency is low.

[0004] With the improvement of the speed performance of corrugated paper automatic printing slotting machines and corrugated paper automatic die-cutting machines, higher requirements are also placed on the paper feeding speed and efficiency of automatic paper feeders. How to improve the paper feeding efficiency has become a technical problem that needs to be solved in this field. Utility Model Content

DETAILED DESCRIPTION

[0044] 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.

[0045] refer to Figure 3-9 , showing a corrugated paper turning and loading machine with a telescopic baffle of the utility model, comprising:

[0046] The turning frame comprises a turning frame column 3 and a turning frame transverse plate 15, wherein the turning frame transverse plate 15 is mounted on the turning frame column 3, and the turning frame column is rotatably mounted on the wall panel 2, and the turning frame rotates to stack the corrugated paper onto the corrugated paper conveying platform 1;

[0047] A first telescopic assembly, one end of which is fixed to the wall panel and the other end is hinged to the flip frame, and the first telescopic assembly is used to control the rotation of the flip frame;

[0048] The second telescopic component is installed on the turning frame. The second telescopic component includes a paper stopper 6. When the turning frame turns over the paper, the paper stopper 6 is in an extended state to support the corrugated paper pile. The paper stopper 6 corresponds to the gap position of the conveyor belt 26 of the corrugated paper conveyor platform 1.

[0049] In the embodiment of the utility model, when the corrugated paper pile is automatically transported to the paper feed platen 14 at the position of the overturning frame frame through the corrugated paper conveyor line, the corrugated paper pile is positioned at the front positioning paper stopper 25. At this time, the paper stopper 6 is extended to support the corrugated paper pile. At the same time, the paper feed platen cross piece 13 is driven by the paper feed platen driving mechanism 19 to drive the paper feed platen 14 to gradually raise the corrugated paper pile by using the paper feed platen slide rail 21. In addition, the first telescopic component also synchronously drives the overturning frame to drive the corrugated paper pile to overturn. Generally speaking, when the first telescopic component drives Before the turning frame is turned over to the extreme position, the paper feeding table 14 pushes all the corrugated paper piles onto the paper baffle 6. When the first telescopic component drives the turning frame to turn over to the extreme position, the paper baffle 6 sinks into the gap position of the conveyor belt 26 of the corrugated paper conveyor 1, so that the corrugated paper pile is completely stacked on the conveyor belt 26 of the corrugated paper conveyor 1. The corrugated paper moves forward with the conveyor belt 26. During the forward movement of the corrugated paper, the paper baffle 6 retracts, and the first telescopic component controls the turning frame to return to the paper loading position to continue to receive the next corrugated paper pile. Since the utility model realizes the direct placement of the entire stack of corrugated paper piles onto the conveyor belt 26, at least the time of waiting for the corrugated paper piles to be gradually transported is saved. Therefore, the paper loading efficiency of the corrugated paper piles is greatly improved, and the paper loading time is saved.

[0050] It should be noted that a section of the corrugated paper conveyor 1 of the utility model close to the turning frame (the length of which is at least greater than the height of the corrugated paper pile) can be set as an inclined surface, and the height of the inclined surface gradually decreases from the point where the corrugated paper conveyor 1 is closest to the turning frame to the direction away from the turning frame, so that when the corrugated paper pile is placed on this section of the corrugated paper conveyor, the paper surface of the corrugated paper pile forms an acute angle with the corrugated paper feeder. As the paper feed belt of the corrugated paper feeder moves forward, the corrugated paper on the corrugated paper feeder can be sent to the position of the paper feed part of the printing slotting machine or the automatic die-cutting machine in a fish scale shape.

[0051] In a specific embodiment, reference Figure 7 , Figure 8 and Fig. 9 The flip frame column 3 includes a transmission side flip column 18 and an operation side flip column 24;

[0052] The turning frame transverse plate 15 includes a transmission side turning frame transverse plate 20 and an operation side turning frame transverse plate 22;

[0053] One end of the transmission side flip column 18 is installed on the transmission side wall plate 16 through the transmission side flip frame rotation shaft 7, and the other end is connected to the transmission side flip frame cross plate 20, and the transmission side flip column 18 is perpendicular to the transmission side flip frame cross plate 20;

[0054] One end of the operating side flip column 24 is installed on the operating side wall plate 27 through the operating side flip frame rotation axis 23, and the other end is connected to the operating side flip frame cross plate 22, and the operating side flip column 24 is perpendicular to the transmission side flip frame cross plate 20;

[0055] The transmission side overturn frame rotation axis 7 is coaxially arranged with the central axis of the operation side overturn frame rotation axis 23 and is perpendicular to the conveying direction of the corrugated paper pile;

[0056] A support 9 is installed between the transmission side flip column 18 and the operation side flip column 24 .

[0057] Preferably, the transmission side flip column 18 is parallel to the operation side flip column 24;

[0058] The transmission side overturn frame transverse plate 20 is parallel to the operation side overturn frame transverse plate 22;

[0059] The support block 9 is arranged along a direction perpendicular to the transmission-side flip column 18 .

[0060] More preferably, the number of the support 9 is at least one. Understandably, the number of the support is generally multiple, such as 3, 4, 5 or 10 or more, and the more the relative number of the support, the better the supporting effect.

[0061] In a specific embodiment, the first telescopic assembly includes a transmission side hydraulic cylinder 17 and an operating side hydraulic cylinder 28;

[0062] One end of the transmission side hydraulic cylinder 17 is hinged to the transmission side wall plate 16, and the other end is hinged to the transmission side flip column 18;

[0063] One end of the operating side hydraulic cylinder 28 is hinged to the operating side wall plate 27 , and the other end is hinged to the operating side flip column 24 .

[0064] In the embodiment of the utility model, the transmission side hydraulic cylinder 17 and the operating side hydraulic cylinder 28 are respectively installed at symmetrical positions of the transmission side wall panel 16 and the operating side wall panel 27, and the two act synchronously to realize the flipping control of the flip frame frame. The operation here is similar to that in the prior art and will not be repeated here.

[0065] In a specific embodiment, the second telescopic assembly further includes a paperboard stopper telescopic cylinder 4 and a slide rail 11;

[0066] The end of the top rod of the telescopic cylinder 4 is connected to the paperboard baffle top plate 5 of the paperboard baffle 6;

[0067] The slide rail 11 is installed on the support 9 and is arranged in a direction parallel to the transmission side flip column 18 .

[0068] Specifically, the paper baffle 6 is slidably mounted on the slide rail 11 through an upper slide rail seat 10 and a lower slide rail seat 12;

[0069] When the top rod of the telescopic cylinder 4 is extended or retracted, the paper baffle plate 6 is driven to slide along the slide rail 11 through the paper baffle plate top plate 5 .

[0070] Specifically, the paper baffle telescopic cylinder 4 is mounted on one of the support rails 9 via a cylinder mounting frame 8 .

[0071] Preferably, the second telescopic assembly is at least one set. Understandably, the second telescopic assembly is generally multiple sets, such as 3 sets, 5 sets or more sets. The more second telescopic assemblies there are, the better the support for the corrugated paper. It should be noted that the multiple sets of second telescopic assemblies need to act synchronously, which can be achieved by existing technology and will not be described in detail.

[0072] refer to Figure 3 , Figure 7 and Figures 10A-10D , the working principle of the utility model is as follows:

[0073] The corrugated paper pile is automatically transported to the top of the paper feeding plate 14 at the position of the turning frame frame through the corrugated paper conveying line, and is positioned on the front positioning paper stopper. At this time, the top rods of the paper stopper telescopic cylinders 4 extend out, and drive the paper stoppers 6 to extend upward through the paper stopper top plate 5 (understandably, it refers to including several groups of second telescopic components here), such as Fig. 10A At the same time, the paper feeding platen driving mechanism 19 drives the paper feeding platen 14 to move upward, lifting the corrugated paper pile, and the overturning frame is overturned counterclockwise under the drive of the transmission side hydraulic cylinder 17 and the operation side hydraulic cylinder 28. During the overturning process, the paper feeding platen 14 continues to lift the corrugated paper pile upward, so that the side of the corrugated paper pile is against the paper stop surface of several paper stop boards 6, and the corrugated paper board on the top surface of the corrugated paper pile is close to the top plate 5 of the paper stop board 6. Fig. 10B When the turning frame is turned counterclockwise to the limit position (or set position), the paper stopper surface of the paper stopper 6 just sinks into the empty space (gap) of the conveying belt 26 of the corrugated paper conveying platform 1, so that the corrugated paper originally carried by the paper stopper 6 is stacked on the conveying belt 26 of the corrugated paper conveying platform 1, as shown in FIG. Fig. 10CAs shown. After the corrugated paper pile is carried by the conveyor belt 26, the top rods of several paper baffle telescopic cylinders 4 are retracted, and several paper baffles 6 are retracted to the initial position through the paper baffle top plate 5. After several paper baffles 6 are retracted to the initial position, the transmission side hydraulic cylinder 17 and the operating side hydraulic cylinder 28 drive the flip frame frame to flip clockwise, and at the same time, the paper feed table driving mechanism 19 drives the paper feed table 14 to fall back and stop at the initial position. As the conveyor belt 26 of the corrugated paper conveyor 1 moves forward, the corrugated paper carried on the conveyor belt 26 of the corrugated paper conveyor 1 is gradually transported in a fish scale shape and fed into the paper feeding section of the corrugated paper printing slotting machine or the corrugated paper automatic die-cutting machine, see Fig. 10D At this time, the next pile of corrugated paper is sent to the position of the turning frame frame and enters the next working cycle.

[0074] The utility model is achieved through the following measures:

[0075] On both sides of the operating surface and the transmission surface of the corrugated paper turning and loading machine, along the movement direction of the corrugated paperboard, a transmission side wall panel 16 (2) and an operation surface wall panel 27 (2) are fixed respectively. One end of the transmission side turning frame rotating shaft 7 and the operation side turning frame rotating shaft 23 are supported and installed at the symmetrical positions of the transmission side wall panel 16 (2) and the upper right corner of the operation surface wall panel 26 (2) respectively. The other end of the transmission side turning frame rotating shaft 7 is fixedly connected to the upper part of the transmission side turning frame column 18 (3); the other end of the operation side turning frame rotating shaft 23 is fixedly connected to the upper part of the operation side turning frame column 24 (3), and the fixing positions of the rotating shaft 7 and the rotating shaft 23 are coaxially symmetrical. The transmission side turning frame column 18 (3) and the operation side turning frame column 24 (3) together with the transmission side turning frame cross plate 20 (15) and the operation side turning frame cross plate 22 (15) and a plurality of supporting blocks 9 constitute a turning frame frame. The transmission side turning frame rotating shaft 7 and the operation side turning frame rotating shaft 23 support the turning frame frame of the corrugated paper turning machine between the transmission side wall panel 16 (2) and the operation side wall panel 27 (2). The turning frame frame can rotate along the coaxial transmission side turning frame rotating shaft 7 and the operation side turning frame rotating shaft 23.

[0076] On the several struts 9 of the flip frame frame, a plurality of slide rails 11 are fixedly installed perpendicularly and parallel to the struts 9. On the middle and lower parts of the plurality of paper baffles 6, an upper slide rail seat 10 and a lower slide rail seat 12 are fixedly installed, respectively, and the upper slide rail seat 10 and the lower slide rail seat 12 can slide along the slide rail 11. On the middle strut 9, corresponding to each slide rail 11, a cylinder mounting frame 8 is fixedly connected, and a plurality of paper baffle telescopic cylinders 4 are vertically fixed on the cylinder mounting frame 8 respectively. The top rod of the paper baffle telescopic cylinder 4 is connected to the paper baffle top plate 5, and the paper baffle top plate 5 is fixed to the top of the paper baffle 6. When the top rod of the paper baffle telescopic cylinder 4 is extended, the paper baffle top plate 5 drives the paper baffle 6 to be pushed upward along the slide rail 11. The paper baffle surface of the paper baffle 6 is slightly lower than the front positioning paper baffle 25 positioned on the side of the corrugated paper pile. A paper feed platen driving mechanism 19 is also installed on the turning frame column 18 on the transmission side of the turning frame frame. The paper feed platen driving mechanism 19 can drive the paper feed platen cross piece 13 and a plurality of paper feed platens 14 fixedly connected to the paper feed platen cross piece 13 to move up and down, and can lift the corrugated paper pile positioned above the plurality of paper feed platens 14.

[0077] A transmission side hydraulic cylinder 17 and an operating side hydraulic cylinder 28 are fixedly mounted on the transmission side wall panel 16 (2) and the operating side wall panel 27 (2). The top rods of the transmission side hydraulic cylinder 17 and the operating side hydraulic cylinder 28 are respectively connected to the middle of the transmission side flip frame column 18 (3) and the operating side flip frame column 24 (3). When the top rods of the transmission side hydraulic cylinder 17 and the operating side hydraulic cylinder 28 are extended, the flip frame frame can be pushed to rotate along the transmission side flip frame rotation axis 7 and the operating side flip frame rotation axis 23 fixedly mounted on the transmission side wall panel 16 (2) and the operating side wall panel 26 (2). When the flip frame frame rotates counterclockwise to the limit position (see Fig. 10C ), the paper blocking surface of the paper blocking paper 6 is just immersed in the gap of the conveying belt 26 of the corrugated paper conveying platform 1, so that the paper blocking surface of the paper blocking paper 6 is slightly lower than the upper conveying surface of the conveying belt 26.

[0078] During operation, the corrugated paper pile is transported to the paper feeding platen 14 at the position of the turning frame frame through the corrugated paper conveying line, and the side of the corrugated paper pile is positioned at the front positioning paper stopper 25. The paper feeding platen driving mechanism 19 drives the paper feeding platen 14 to move upward, lift the corrugated paper pile, and the top rods of the paper stopper telescopic cylinders 4 extend to drive the paper stoppers 6 to push upward along the slide rail 11. At the same time, when the top rods of the transmission side hydraulic cylinder 17 and the operating side hydraulic cylinder 27 extend, the turning frame is pushed to rotate counterclockwise along the transmission side turning frame rotating shaft 7 and the operating side turning frame rotating shaft 23. In this process, as the paper feeding platen 14 moves upward, the side of the corrugated paper pile gradually leans against the paper stopper surface of the paper stopper 6. When the paper stoppers 6 extend and move to their highest position, the paper feeding platen 14 lifts the corrugated paper on the top surface of the corrugated paper pile to a position close to the top plate 5 of the paper stopper 6, so that the side of the corrugated paper pile leans against the paper stopper surface of the paper stoppers 6. When the turning frame is turned counterclockwise to its limit position, the paper stopper surfaces of the plurality of paper stoppers 6 are just immersed in the gap of the conveyor belt 26 of the corrugated paper conveyor 1, and the side of the corrugated paper pile is placed on the conveyor belt 26 of the corrugated paper conveyor 1 (see Fig. 10C ). With the movement of the conveyor belt 26, the corrugated paperboard gradually forms a fish scale-like conveyor and is fed into the paper feeding section of the corrugated paper printing slotting machine or the corrugated paper automatic die-cutting machine. After the corrugated paper is stacked on the conveyor belt 26 of the corrugated paper conveyor 1, a number of paperboard retaining plates 6 are retracted to the initial position, the top rods of the transmission side hydraulic cylinder 17 and the operating side hydraulic cylinder 27 are retracted, and the flip frame frame is driven to flip clockwise along the transmission side flip frame rotating shaft 7 and the operating side flip frame rotating shaft 23 back to the initial position, and at the same time, the paper feeding plate driving mechanism 19 drives the paper feeding plate 14 to move downward, so that the paper feeding plate 14 returns to the initial position. At this time, the corrugated paper flipping loading machine enters the next working cycle.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
