Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, and in particular to a packaging box die-cutting waste cleaning mechanism and a full-automatic waste cleaning machine with compact structure, simple adjustment, quick needle replacement and good waste cleaning effect. Background Art

[0002] Die-cutting is a cutting process for the post-processing of printed products. It is to make a die-cutting blade according to the pre-designed pattern of printed products or other paper products, and cut or press lines on printed products and other paper products through pressure, so that the shape of the product is no longer limited to the straight edge and right angle forming process. Usually, the die-cutting process is to combine the die-cutting knife and the creasing knife in the same template, and perform die-cutting and creasing processing on the die-cutting machine at the same time.

[0003] After the die-cutting process of printed materials or other paper products, there are still some areas between the waste and the materials to be cleaned. It is necessary to separate the waste and the materials to be cleaned by manual or mechanical pressing, which is the cleaning operation. The existing manual cleaning or mechanical cleaning both apply pressure on the upper surface of the waste to force the waste to be disconnected from the materials to be cleaned, but it is often the case that only one side of the waste is disconnected from the materials to be cleaned, while the other side is still connected. At this time, when only the upper surface of the waste is under force, it will flip along the edge of the side connected to the materials to be cleaned, causing the cleaning process to be interrupted, thereby affecting production efficiency.

[0004] At present, in order to solve the problem of interruption of waste cleaning caused by applying pressure on the upper surface of the waste, a horizontal machine body is generally set up, and a clamping plate for clamping the packaging box cardboard to be cleaned is set on the machine body, and a cavity is opened in the machine body, and a push rod is set in the cavity for sliding along the vertical direction. A through hole for the push rod to pass through is opened at one end of the machine body facing the clamping plate. The machine body is also provided with a paper pressing frame for pressing the packaging box cardboard, and then the pressing frame is driven by power to press the packaging box cardboard tightly on the clamping plate, and then the push rod is driven to extend from the through hole to push the retained part of the packaging box out of the cardboard, while the waste remains between the clamping plate and the paper pressing frame and is cleared. However, the existing ejector pin cleaning mechanism has a large number of ejectors. When different packaging boxes are being cleaned or some ejectors need to be replaced, the different installation structures of the ejectors will lead to significantly different adjustment workloads. For example, the existing ejectors mostly adopt a double-layer clamping structure of a fixed plate and a pressure plate, and the bottom of the ejector is designed to be a stepped shaft. The large shafts at the bottom of each ejector are respectively inserted into the corresponding through holes of the lower pressure plate, and then the small shafts of the ejectors are tightly fitted through the through holes on the fixed plate. Finally, the pressure plate is fastened to the bottom of the fixed plate with screws to clamp and fix the ejectors, thereby fixing the ejectors. However, since the entire pressure plate needs to be separated from the fixed plate for adjustment or replacement of some ejectors, the replacement process is cumbersome and difficult, and it often takes half a day to complete the replacement. To this end, in the prior art, a plurality of sliding bars parallel to each other are provided on the ejector mounting plate, and mounting half holes I or inclined surfaces I which are tightly matched with the ejector are arranged at intervals on the mating surface on one side of the adjacent mating surface of the sliding bar, and mounting half holes II or inclined surfaces II which are larger in diameter than the ejector and eccentric are arranged at corresponding intervals on the mating surface on the other side of the adjacent mating surface. Finally, the ejector is placed between the mounting holes or inclined surfaces by sliding and dislocating the two sliding bars on the adjacent mating surfaces, and then the two sliding bars are pushed to shift and clamp the ejector, so as to complete the replacement of a row of ejector pins. Although the replacement efficiency is greatly improved compared with the double-layer clamping structure, the entire row of ejector pins needs to be moved each time the replacement is made, which makes it difficult to achieve on-demand replacement. The replacement efficiency is still cumbersome and inefficient when the ejector pins along the edge change greatly. In addition, in the prior art, air cylinders or hydraulic cylinders are mostly used to drive the push rods to move up and down. Although the driving structure is relatively simple, the stroke of the air cylinder and the hydraulic cylinder often needs to be coordinated with a travel switch or a grating ruler to be effectively controlled. The travel switch needs to be readjusted when clearing waste from different paper boxes to achieve control, which makes the adjustment process more cumbersome and the control accuracy is low. Although the grating ruler does not need to be adjusted and has a high control accuracy, the cost is too high. Moreover, the driving process of the air cylinder and the hydraulic cylinder is not smooth enough, which can easily cause the push rod to be damaged by instantaneous overload. Although it can be improved by proportional valves, buffer valves, etc., it will make the fluid control circuit too complicated. Summary of the invention

[0036] Working principle and working process of the present invention: like Figures 1 to 13 As shown, before waste cleaning, the mold 22 is prepared according to the pre-cleaned waste shape of the die-cut product to be cleaned, and then the corresponding mold 22 is installed on the mold mounting plate 21. Then, according to the pre-retained finished product shape of the die-cut product to be cleaned, the ejector clamping plate 52 and the ejector mounting plate 53 are first loosened, and then the ejector 51 is installed in the waist hole 521 of the ejector clamping plate 52 where the ejector 51 is needed: first, the ejector 51 is rotated so that the ejector handle 513 passes through the waist hole 521 And the fixing handle 514 is inserted into the mounting hole 531 of the ejector mounting plate 53, and then the ejector 51 is rotated 90° again, so that the ejector handle 513 and the waist hole 521 are misaligned to limit the axial freedom of the ejector handle 513, and then the ejector 51 to be removed is rotated to separate it from the ejector clamping plate 52 and the ejector mounting plate 53, and finally the ejector mounting plate 53 and the ejector clamping plate 52 are tightened to clamp each ejector 51, thereby completing the disassembly, assembly and fixation of the ejector 51.

[0037] During waste cleaning, the die-cut products to be cleaned are first neatly stacked on the table of the pushing mechanism 1A, and then the waste cleaning machine is started. The pushing mechanism 1A feeds the die-cut products to be cleaned on the table onto the support plate 4 of the waste cleaning mechanism. Subsequently, the cylinder I (i.e., the mold driving unit 3) of the waste cleaning mechanism is started to drive the mold mounting plate 21 together with the mold 22 to move downward along the guide rod 7, and the waste part of the die-cut products to be cleaned is pressed by the mold 22; then the driving motor 62 is started to drive the screw rod 61 to rotate through the driven wheel 63, and the rotating screw rod 61 drives the ejector assembly 5 to move upward along the guide rod 7 through the nut 64 and the support frame 65, and each ejector 51 on the upwardly moving ejector assembly 5 passes through the corresponding ejector hole 41 on the support plate 4, and the retained part of the die-cut products to be cleaned is lifted up, completing the separation of the waste and the finished products of the products to be cleaned.

[0038] During discharging, after the waste is separated from the finished product, the adjusting cylinder 974 is started to move the comb-shaped picking robot 94 to the bottom of the finished product after the waste is cleared, and then the cylinder II (i.e., the lifting drive unit 95) is started to lift the finished product after the waste is cleared upward through the picking robot 94, and then the picking motor 91 is started to drive the fixed seat 96 to slide along the picking guide rail 92 through the synchronous belt (i.e., the picking belt 93), and the sliding picking guide rail 92 drives the cylinder II to drag the auxiliary fixed seat 971 to slide along the picking guide rail 92, and drives the picking robot 94 and the finished product thereon to move to the feeding roller 1D of the stacking mechanism, and finally the finished product is stacked by the stacking mechanism. After the finished product is extracted upward, the drive motor 62 reverses and drives the ejector assembly 5 to move downward. At the same time, the cylinder I drives the mold mounting plate 21 and the mold 22 to move upward along the guide rod 7, leaving the waste on the support plate 4. Then the propulsion mechanism 1A pushes the next stack of die-cut products to be cleaned into the support plate 4. When the next stack of die-cut products to be cleaned is pushed in, the waste is pushed away from the support plate 4 and enters the waste conveyor belt 1B and finally falls into the waste box 1C. Then the above process is repeated to complete the cleaning of the next stack of die-cut products to be cleaned.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
