Description

Technical Field

[0001] The utility model relates to the technical field of packaging box manufacturing, and particularly relates to a waste cleaning device for improving the production efficiency of processes. Background Art

[0002] Products such as commodity packaging boxes are usually processed by die cutting.

[0003] After die cutting is completed, most of the cut parts will fall off from the main body during transportation and enter the waste collection channel for centralized recycling; however, there are also some areas where die cutting adhesion occurs, which will cause blockage of the paper feeding channel. Therefore, semi-automatic waste cleaning or manual waste cleaning can only be carried out centrally after die cutting.

[0004] The so-called manual waste cleaning is to gather the printed products and manually separate the parts with die cutting adhesion. This process causes product deformation, affects quality, and has low production efficiency.

[0005] In addition, some enterprises also use mechanical assistance to deal with the adhered parts during manual waste cleaning, lifting or pressing the stacked adhered parts in order to achieve the purpose of eliminating adhesion. However, the operability of this solution is poor, and problems such as product scattering, machine jamming, and product damage often occur, and the effect of eliminating adhesion in the middle part of the printed products stacked together is poor.

[0006] For some printed products with relatively complex die cutting layout, the die-cut parts require small waste cleaning area and long length, and the surrounding parts have a high clamping degree on the waste cleaning parts. Only the number of waste cleaning per time can be reduced, the waste cleaning speed is slow, and the waste cleaning effect is difficult to guarantee. Coupled with the inherent problems of manual waste cleaning such as poor working environment, pollution, and high labor intensity, there is an urgent need to provide a waste cleaning device and means that can improve the production efficiency of processes and eliminate the above problems. Summary of the Invention

[0007] To solve the above problems, the utility model provides a waste cleaning device for improving the production efficiency of processes, which solves the problems of low die cutting production efficiency, high labor intensity, and low product qualification rate in the prior art.

[0008] The utility model adopts the following technical solutions. A waste cleaning device for improving the production efficiency of processes is characterized in that it includes an extrusion waste cleaning mechanism arranged behind the die cutting mechanism 1, as well as a waste collection mechanism and a finished product collection mechanism;

[0009] The extrusion waste cleaning mechanism is arranged on the conveying platform 2 on one side of the outlet end of the die cutting mechanism 1, and includes a side part and a middle part;

[0010] The side part of the extrusion waste cleaning mechanism includes the upper convex bending wheels 3 and the lower convex bending wheels 4 arranged on both sides of the conveying platform 2, as well as the paper pressing wheel 5 arranged in the middle and the conveyor belt 6 opposite to the paper pressing wheel 5; the upper convex bending wheels 3 and the lower convex bending wheels 4 are synchronously rotated by the driving motor 7 and the transmission device 8 arranged on the side, and the paper pressing wheel 5 presses the printed matter to generate friction with the conveyor belt 6 for transmission; the upper convex bending wheels 3 and the lower convex bending wheels 4 are installed inside the edge of the conveying platform 2, and the upper convex bending wheels 3 and the lower convex bending wheels 4 on the other side are symmetrically installed;

[0011] The upper convex bending wheels 3 and the lower convex bending wheels 4 on both sides are both installed through the horizontal brackets 9 horizontally arranged above the conveying platform 2 and the positions are adjustable; in addition, a longitudinal bracket 10 is arranged in the middle of the conveying platform 2, the paper pressing wheel 5 is installed below the longitudinal bracket 10, and a conveyor belt 6 is arranged below the paper pressing wheel 5, and the two cooperate to position and convey the printed matter to assist the upper convex bending wheels 3 and the lower convex bending wheels 4 to align with the edges of the corresponding sides of the printed matter; bending rings are sleeved outside the upper convex bending wheels 3 and the lower convex bending wheels 4, and convex blocks with the same contour and size as the parts to be cleaned after die-cutting on the edge of the printed matter are arranged on the bending rings, and the convex blocks are evenly distributed on the outer circumference of the bending rings at certain intervals, and the arc length between the center points on the equal radius of adjacent convex blocks is the same as the straight-line distance between the adjacent parts to be cleaned on the edge of the printed matter;

[0012] The middle part of the extrusion waste cleaning mechanism also includes the upper convex bending wheels 3 and the lower convex bending wheels 4 arranged above the conveying platform 2, between the two paper pressing wheels 5, installed through the horizontal brackets 9 and the positions are adjustable, and the structure is the same as that of the side part, and the working principle and process are also the same; the moving speed of the printed matter is the same as the linear speed of the rotation of the upper convex bending wheels 3 and the lower convex bending wheels 4 in the middle part and the side part of the extrusion waste cleaning mechanism. During the movement process, the convex blocks arranged on the upper convex bending wheels 3 and the lower convex bending wheels 4 can accurately press and bend the parts that need to be cleaned on the edge or in the middle of the printed matter from the upper and lower directions, eliminate the die-cut adhesion between the die-cut part and the main body of the printed matter, and make the die-cut part fall off.

[0013] Printed materials with complex layouts are more likely to have die-cutting adhesion problems. Especially for die-cutting areas with small sizes and many lines, a dedicated waste removal mechanism needs to be set according to the pattern distribution. Therefore, a lifting waste removal mechanism for printed materials with complex layouts is set behind the extrusion waste removal mechanism. By setting a clamping device, small die-cut waste materials are temporarily fixed, and then lifted to separate from the printed material body, thus achieving waste removal. The lifting waste removal mechanism is disposed on the upper and lower sides of the conveying platform 2. It also includes a suspended bracket 11 above the conveying platform 2 and a base below the conveying platform 2, with their positions opposite to each other. Below the suspended bracket 11, an upper platform 12, a printed material positioning frame 13, an induction probe, and corresponding driving mechanisms are installed. Above the base, a lower platform 14 and corresponding driving mechanisms are set. The upper and lower sets of driving mechanisms are simultaneously connected to the controller, which coordinates and controls the telescopic actions. The upper platform 12 and the lower platform 14 are opposite in position, and the conveying platform 2 has a longitudinal partial hollow structure in the area where they are opposite to each other.

[0014] The lower platform 14 is a plate member, and its surface is provided with concave and convex patterns that match the longitudinal hollow structure of the conveying platform 2. Several through holes 15 are provided on the convex surface. The positions of the through holes 15 are within the hollow area of the conveying platform 2 and are opposite to the die-cut waste materials on the printed material, and the area of the through hole 15 part is larger than the area of the die-cut waste materials on the printed material. The upper platform 12 opposite to the lower platform 14 is a double-layer square hollow bracket with the same area as the lower platform 14. On the surface of the upper-layer hollow bracket 16, hollow structure protrusions 17 with the same positions and quantities as the through holes 15 of the upper platform 12 are provided. The upper and lower layer hollow brackets 19 overlap each other, and an elastic member 18 is provided between them. A waste removal needle 20 is provided on the lower layer hollow bracket 19. The waste removal needle 20 penetrates into the corresponding protrusion 17 on the upper-layer hollow bracket 16, and its end portion passes through the hollow part on the upper surface of the protrusion 17. When the upper platform 12 and the lower platform 14 are in contact, the end portion of the waste removal needle 20 can extend into the through hole 15.

[0015] The printed material positioning frame 13 provided in front of the upper platform 12 is movably connected to the suspended bracket 11 through a cantilever 21, and a cylinder 22 is set to control its lifting.

[0016] Preferably, a transverse cleaning device is provided behind the extrusion waste removal mechanism. A transverse through bracket of a gantry type is erected above the conveying platform 2, and a cleaning brush covering the entire width direction of the conveying platform 2 is provided on the through bracket.

[0018] ①The waste cleaning device described in this application is specifically provided with two - stage waste cleaning mechanisms, which are used for die - cut waste with different positions and sizes.

After cleaning the die - cut waste with small area and high texture load, the working hours for tearing the box can be reduced by more than half, greatly improving the production efficiency of the box - tearing process and reducing the labor intensity.

Moreover, the accompanying drawings are all in a very simplified form, using non-precise ratios, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present utility model. Embodiment 1

[0031] Referring to FIGS. 2, 3, and 5, a waste cleaning device for improving the production efficiency of a lifting process in this embodiment includes an extrusion waste cleaning mechanism arranged behind the die-cutting mechanism 1, as well as a waste collection mechanism and a finished product collection mechanism; the extrusion waste cleaning mechanism is arranged on the conveying platform 2 on one side of the outlet end of the die-cutting mechanism 1, and includes a side part and a middle part; the side part of the extrusion waste cleaning mechanism includes an upper convex bending wheel 3 and a lower convex bending wheel 4 arranged on both sides of the conveying platform 2, as well as a paper pressing wheel 5 arranged in the middle and a conveyor belt 6 opposite to the paper pressing wheel 5; the upper convex bending wheel 3 and the lower convex bending wheel 4 are synchronously rotated through a driving motor 7 and a transmission device 8 arranged on the side, and the paper pressing wheel 5 presses the printed matter to generate a frictional force with the conveyor belt 6 for transmission; the upper convex bending wheel 3 and the lower convex bending wheel 4 are installed inside the edge of the conveying platform 2, and the upper convex bending wheel 3 and the lower convex bending wheel 4 on the other side are symmetrically installed; the upper convex bending wheels 3 and the lower convex bending wheels 4 on both sides are installed through a transverse bracket 9 arranged above the conveying platform 2 and their positions are adjustable; in addition, a longitudinal bracket 10 is arranged in the middle of the conveying platform 2, the paper pressing wheel 5 is installed below the longitudinal bracket 10, and a conveyor belt 6 is arranged below the paper pressing wheel 5. The two cooperate to position and convey the printed matter, and assist the upper convex bending wheel 3 and the lower convex bending wheel 4 to align with the edges of the corresponding sides of the printed matter; bending rings are sleeved around the outer peripheries of the upper convex bending wheel 3 and the lower convex bending wheel 4, and convex blocks with the same contour and size as the parts to be cleaned after die-cutting of the printed matter edge are arranged on the bending rings. The convex blocks are evenly distributed on the outer circumference of the bending ring at a certain interval, and the arc length between the center points on the same radius of adjacent convex blocks is the same as the straight-line distance between the adjacent parts to be cleaned of the printed matter edge.

[0032] The middle part of the extrusion waste cleaning mechanism also includes an upper convex bending wheel 3 and a lower convex bending wheel 4 which are arranged above the conveying platform 2, between two paper pressing wheels 5, installed through a transverse bracket 9 and have adjustable positions. The structure is the same as that of the side part, and the working principle and process are also the same. The moving speed of the printed matter is the same as the linear speed of the rotation of the upper convex bending wheel 3 and the lower convex bending wheel 4 in the middle part and the side part of the extrusion waste cleaning mechanism. During the movement, the convex blocks provided on the upper convex bending wheel 3 and the lower convex bending wheel 4 can accurately press and bend the edge of the printed matter or the part to be cleaned in the middle from the upper and lower directions, eliminating the die-cut adhesion between the die-cut part and the main body of the printed matter, and making the die-cut part fall off. The waste collection mechanism includes a strip-shaped waste slot 23 running through the entire waste cleaning device and a matching collection belt 24. The waste slot 23 and the collection belt 24 are installed below the waste cleaning device. The fallen die-cut waste is guided and collected through the waste slot 23 and finally falls onto the collection belt 24 and is centrally sent to the collection container. Embodiment 2

[0033] Reference Figure 1 、 4 、6, 7, 8, 9. Compared with Embodiment 1, small waste cleaning points with a dovetail shape, as shown in Figure 8 and 9 , are added to the printed matter. Due to their small area and complex lines, they are difficult to clean during the box tearing process. Therefore, a special lifting waste cleaning mechanism is arranged behind the above-mentioned extrusion waste cleaning mechanism to clean them during the waste cleaning process after die-cutting, avoiding increasing the difficulty of manual box tearing at the end.

[0034] The lifting waste cleaning mechanism is disposed on the upper and lower sides of the conveying platform 2, and further includes a suspended bracket 11 located above the conveying platform 2 and a base located below the conveying platform 2, and their positions are opposite. An upper platform 12, a printed matter positioning frame 13, an induction probe and corresponding driving mechanisms are installed below the suspended bracket 11. A lower platform 14 and corresponding driving mechanisms are arranged above the base. The upper and lower sets of driving mechanisms are simultaneously connected to the controller, and their telescopic actions are coordinated and controlled by it. The upper platform 12 and the lower platform 14 are opposite in position. The conveying platform 2 is provided with a longitudinal partial hollow structure in the area where they are opposite. The printed matter positioning frame 13 arranged in front of the upper platform 12 is movably connected to the suspended bracket 11 through a cantilever 21, and a cylinder 22 is provided to control its lifting.

[0035] The lower platform 14 is a plate, and its surface is provided with concave and convex patterns that match the longitudinal hollow structure of the conveying platform 2. A plurality of through holes 15 are provided on the convex surface. The through holes 15 are located in the hollow area of the conveying platform 2 and are opposite to the die-cutting waste on the printed matter. The through holes 15 are larger than the area of the die-cutting waste on the printed matter. The upper platform 12 opposite to the lower platform 14 is a double-layer square hollow bracket with the same area as the lower platform 14, wherein the surface of the upper hollow bracket 16 is provided with through holes whose positions and numbers are the same as those of the upper platform 12. 15 has a hollow structure protrusion 17 that is consistent with the upper and lower hollow brackets 19, and an elastic component 18 is arranged between them. A waste cleaning needle 20 is arranged on the lower hollow bracket 19, and the waste cleaning needle 20 penetrates into the protrusion 17 on the upper hollow bracket 16 that is opposite to it, and its end portion passes through the hollow portion of the upper surface of the protrusion 17. When the upper platform 12 and the lower platform 14 are in contact, the end portion of the waste cleaning needle 20 can extend into the through hole 15 to separate the die-cutting waste from the printed product body. The die-cutting waste passes through the through hole 15 and falls onto the collecting belt 24 through the waste groove 23.

[0036] In specific operation, after die-cutting, the printed product undergoes a waste cleaning operation of the extrusion waste cleaning mechanism and a cleaning operation of the horizontal cleaning device, and then is transported to the bottom of the suspended bracket 11 through the conveying platform 2. After the induction probe on the suspended bracket 11 detects the printed product, the controller first instructs to lower the printed product positioning frame 13 to position the printed product at a preset position. At this time, the die-cutting waste on the printed product is just located in the longitudinal hollow area of the conveying platform 2, and then the upper platform 12 is pressed down, and the lower platform 14 rises. The printed product is in the middle, and the die-cutting waste on the printed product is facing the space formed by the through hole 15 on the lower platform 14. The protrusion 17 of the upper platform 12 fits with the upper surface of the die-cutting waste. Then, the waste cleaning needle 20 on the lower hollow bracket 19 of the upper platform 12 falls, pressing the die-cutting waste of the printed product downward to separate it from the printed product body and fall into the through hole 15 of the lower platform 14. The pulse air pipe that opens obliquely downward is connected to the inner wall of the through hole 15 to blow the removed die-cutting waste into the waste trough 23.
