Description

Technical Field

[0001] This utility model belongs to the field of combined printing technology and relates to a device for cleaning up waste paper edges after combined printing. Background Technology

[0002] When printing products are produced in a printing plant, in addition to the regular printed products, there are often some waste paper edges that need to be cleaned. Currently, the methods used to clean waste paper edges are generally to use manual edge-removing machines or automatic die-cutting machines. However, manual edge-removing machines are too slow, while automatic die-cutting machines require too much investment and are not suitable for small printing plants. In addition, when cleaning waste paper edges, the width of the edges varies, while the size of the needles used to press down on the waste paper edges is generally a uniform specification. When the minimum width of the waste paper edge is smaller than the size of the needle, part of the needle will press on the finished printed product, which may directly interfere with the cleaning of the waste paper edges.

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Reference Figure 1 As shown in Figure 7, this embodiment provides a device for cleaning waste paper edges after combined printing, which includes a frame 100, a first module 1, and a second module 2. The first module 1 and the second module 2 are mounted on the frame 100, and both the first module 1 and the second module 2 are movable relative to the frame 100 in the front-back direction. The terms "up and down" and "front and back" in this document refer to... Figure 1 As shown.

[0034] Furthermore, the first module 1 is used to press down the waste paper edge. The first module 1 has an upper pressure plate 11, an upper force plate 16 and a third drive mechanism 14. The third drive mechanism 14 is specifically a hydraulic cylinder. The upper force plate 16 is located between the hydraulic cylinder and the upper pressure plate 11. The hydraulic cylinder drives the upper pressure plate 11 to move in the vertical direction through the upper force plate 16. The upper pressure plate 11 can slide relative to the upper force plate 16 in the front-back direction.

[0035] The upper pressure plate 11 is provided with a plurality of first mounting holes 12 and a punch 13 inserted into the first mounting holes 12. The diameter of the first mounting holes 12 is 6-7 mm, more specifically, the diameter of the first mounting holes 12 is 6 mm. Furthermore, the upper pressure plate 11 includes a first upper pressure plate 111 and a second upper pressure plate 112 arranged in a vertical direction. The first upper pressure plate 111 and the upper force plate 16 are slidably connected. Both the first upper pressure plate 111 and the second upper pressure plate 112 are provided with first mounting holes 12. The position and spacing of the first mounting holes 12 on the first upper pressure plate 111 and the second upper pressure plate 112 are equal. The punch 13 is disposed between the first upper pressure plate 111 and the second upper pressure plate 112. Specifically, the first upper pressure plate 111 can move relative to the second upper pressure plate 112 in a vertical direction under the action of a hydraulic cylinder.

[0036] Reference Figure 5 As shown, the first upper pressure plate 111 is provided with a guide post 15 and a positioning block 1111. The guide post 15 guides the movement of the first upper pressure plate 112. The positioning block 1111 serves two purposes: firstly, to facilitate the pulling of the first upper pressure plate 111, and secondly, to facilitate the calibration of the position of the first upper pressure plate 111 when it is pushed into the frame 100, so that the first upper pressure plate 111 and the upper force plate 16 are aligned, and to prevent the first upper pressure plate 111 from being pushed in too long.

[0037] Referring to Figures 7(a) and 7(b), the punch 13 consists of a top cover 131 and a needle head 132. The top cover 131 is disposed on the first upper pressure plate 111, and the needle head 132 passes through the first mounting holes 12 on the first upper pressure plate 111 and the second upper pressure plate 112, respectively. The top cover 131 is rectangular in shape, with a length of 8 mm and a width of 5 mm. The needle head 132 has a total length of 151 mm and is cylindrical in shape. The needle head 132 includes a first segment 1321 and a second segment 1322. The first segment 1321 is the segment close to the top cover 131, and the second segment 1322 is the segment away from the top cover 131. The first segment 1321 and the second segment 1322 have the same diameter, or the diameter of the first segment 1321 is larger than the diameter of the second segment 1322. In one embodiment, the first segment 1321 and the second segment 1322 have the same diameter, and the diameter of both the first segment 1321 and the second segment 1322 of the needle 132 is 5-6 mm. Specifically, the diameter of both the first segment 1321 and the second segment 1322 of the needle 132 is 5 mm. In another embodiment, the diameters of the first segment 1321 and the second segment 1322 are different. For strength considerations, the diameter of the first segment 1321 is 5-6 mm, and the diameter of the second segment 1322 is 3-4 mm. Specifically, the diameter of the first segment 1321 is 5 mm, and the diameter of the second segment 1322 is 3 mm. This setting is because the minimum width of some waste paper edges is only 3 mm. More specifically, the length of the first segment 1321 is 65 mm, and the length of the second segment 1322 is 81 mm. The lengths of the first segment 1321 and the second segment 1322 are set for ease of manufacturing and to ensure strength.

[0038] The second module 2 is used to support the printed product. When the first module 1 presses against the edge of the waste paper, the second module 2 starts to work. Furthermore, the second module 2 has a lifting plate 21, a lower force plate 23, a first drive mechanism, and a second drive mechanism 26.

[0039] The first drive mechanism is located directly below the lower force plate 23, and the first drive mechanism is specifically a hydraulic cylinder; the second drive mechanism 26 drives the lifting plate 21 to move in the front-back direction, and the second drive mechanism 26 is specifically a lead screw drive mechanism, including a motor, lead screw 261, lead screw nut and slide rail 262, etc. The motor drives the lead screw to rotate, and the lead screw 261 and lead screw nut are threadedly engaged to drive the lead screw nut to move linearly along the axis of the lead screw 261 to drive the second module 2 to move linearly in the front-back direction.

[0040] Furthermore, the lifting plate 21 is provided with multiple second mounting holes 211 and ejector pins inserted into the second mounting holes 211. The diameter of the second mounting holes 211 is 13-15mm, specifically, the diameter of the second mounting holes 211 is 15mm. The lifting plate 21 is located above the lower force-bearing plate 23, which is located between the second drive mechanism and the lifting plate 21. Specifically, the lifting plate 21 includes a first lifting plate 212 and a second lifting plate 213 arranged vertically. The second drive mechanism and the first lifting plate 212 are connected by a connecting rod. The second drive mechanism drives the first lifting plate 212 to move vertically relative to the second lifting plate 213. Both the first lifting plate 212 and the second lifting plate 213 have second mounting holes 211, and the positions and spacing of the second mounting holes 211 are the same.

[0041] Reference Figure 4 As shown, the first lifting plate 212 is provided with multiple paper-stopping blocks 25. These paper-stopping blocks 25 can handle a large number of printed materials. The purpose of the paper-stopping blocks 25 is to allow the printed materials stacked on the same plane to be aligned.

[0042] The distance between the second lifting plate 213 and the lower support plate 23 is 15-20mm, specifically 20mm. A ejector pin is located between the first lifting plate 212 and the lower support plate 23. The ejector pin has a first end and a second end. A silicone pad is provided on the first end, and a magnet is provided on the second end. Specifically, a first mounting groove is provided on the first end, and the silicone pad is installed in the first mounting groove. A second mounting groove is provided on the second end, and the magnet is installed in the second mounting groove. The silicone pad directly contacts the printed product, effectively protecting it. The lower support plate 23 is made of metal, and the second end of the ejector pin is fixed to the lower support plate 23 by a magnet, making installation convenient and quick.

[0043] Reference Figure 6As shown, the first upper pressure plate 111 is provided with a first scale 24, and the first lifting plate 212 is also provided with a second scale at the same position. The projections of the first scale 24 and the second scale in the horizontal direction coincide. The first scale 24 and the second scale can effectively prevent the ejector pin and the punch 13 from colliding and thus prevent damage to the printed product. Specifically, the longer side and the shorter side of the first upper pressure plate 111 are both provided with a scale, and the position of the printed product in the horizontal direction is determined by these two scales. To elaborate, before the formal waste paper removal, a printed material, usually rectangular, is placed in the center of the first lifting plate 212. One vertex of the printed material is positioned using the first scale 24 to align it. Similarly, a printed material is placed in the same position on the first upper pressure plate 111 (the positions of the printed materials are ensured to be the same using the first and second scales). Then, only the finished printed material is retained on the first upper pressure plate 111, and punches 13 are set around the outer perimeter of the finished printed material. Only the waste paper edge is retained on the first lifting plate 212, and ejector pins are set inside the waste paper edge. Finally, the device is started for an initial test to check whether the punches 13 and ejector pins will collide. If the punches 13 and ejector pins collide, their relative positions need to be adjusted in time.

[0044] The working principle of the waste paper edge cleaning device in this embodiment is as follows:

[0045] First, insert punches 13 into the upper pressure plate 11 of the first module 1. Then, push the first module 1 backwards directly under the frame 100. Next, insert ejector pins into the lifting plate 21 of the second module 2. Place the die-cut printed material on the first lifting plate 212. Push the second module 2 directly under the first module 1. Then, start the first drive mechanism and the third drive mechanism 14. The third drive mechanism 14 drives the upper pressure plate 11 to move downwards until the second upper pressure plate 112 presses down on the printed material. Then, drive the first upper pressure plate 111 downwards. The process begins with the punch 13 pressing down on the edge of the waste paper. Then, the first driving mechanism drives the first lifting plate 212 to move downward relative to the second lifting plate 213, while the ejector pin lifts the printed product upward. Next, the third driving mechanism 14 drives the first upper pressure plate 111 to move upward, and the upper pressure plate 11 moves upward as a whole, separating the punch 13 from the waste paper edge. The second driving mechanism 26 then drives the lifting plate 21 to move forward, and the printed product and the waste paper edge are manually removed. Finally, the first driving mechanism drives the first lifting plate 212 to rise to the initial position, completing the entire process.
