Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to a fixing device for a green and environmentally friendly automatic printing press. Background Technology

[0002] In the printing industry, common printing equipment like German Heidelberg printing presses are often large in size to accommodate multiple different work units in order to achieve efficient printing operations. Taking the paper feeding section as an example, a forklift is generally needed to move the paper stock stored on pallets to the paper feeding mechanism. During paper feeding, the paper stock is transported by a high-speed rotating paper feeding brush.

[0003] However, existing paper feeding mechanisms generally lack the function of securing the paper stock and pallet. This requires forklifts to precisely transport the pallet along with the paper stock to the designated location. If the pallet and paper stock become misaligned during placement, it can easily cause paper jams, thus affecting the normal operation of the printing process. Utility Model Content

[0004] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a green and environmentally friendly fixing device for an automatic printing machine, so as to solve the problem that the paper feeding mechanism in the prior art lacks the ability to adjust the tray and paper material.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a fixing device for a green and environmentally friendly automatic printing machine, comprising: a support plate and a base plate distributed vertically; two symmetrically distributed clamping plates, wherein the clamping plates are slidably connected to the support plate, and the two support plates are connected by a rotating mechanism; wherein the rotating mechanism includes a first rotating plate, the first rotating plate is connected to the clamping plate by a connecting rod, and the first rotating plate rotates to drive the two clamping plates to move closer or further apart.

[0006] Optionally, the support plate has two notches, and a protrusion is fixed on the side of the clamping plate near the support plate, the protrusion being slidably connected within the notch.

[0007] Optionally, a drive plate is fixed on one of the protrusions, and the first rotating plate is rotatably disposed on the side of the support plate near the substrate. Both ends of the first rotating plate are rotatably connected to connecting rods, one of the connecting rods is rotatably connected to the protrusion, and the other connecting rod is rotatably connected to the drive plate.

[0008] Optionally, the drive plate has guide portions at both ends, and the rotating mechanism further includes a first cylinder, the output shaft of the first cylinder being fixedly connected to the guide portions.

[0009] Optionally, the first cylinder is fixed to the support plate and is arranged perpendicular to the clamping plate.

[0010] Optionally, a second guide rod is also fixedly connected to the support plate, and the guide part is slidably connected to the second guide rod.

[0011] Optionally, the support plate is fixed with first guide rods on both sides perpendicular to the clamping plate, and the clamping plate is slidably connected to the first guide rods.

[0012] Optionally, a lifting mechanism is provided between the support plate and the base plate. The lifting mechanism includes two second rotating plates arranged in an X shape. One end of each of the two second rotating plates is rotatably connected to a second fixed block and a movable block, respectively. The other end of each plate is rotatably mounted on the support plate through a first fixed block. The second fixed block is fixed on the base plate, and the movable block is driven by a second cylinder to slide on the base plate.

[0013] Optionally, the second cylinder is fixed on the base plate and is arranged parallel to the clamping plate.

[0014] Optionally, the clamping plate has several grooves on the side near the support plate, and several round steel balls that can roll on the support plate are arranged in the grooves so that the clamping plate can move on the support plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention drives one of the clamping plates to slide on the support plate. A connecting rod and a first rotating plate then drive the other clamping plate to follow suit. Alternatively, the first rotating plate can drive the clamping plates on both sides to move synchronously, either close together or apart. When the paper material placed on the support plate is tilted, the two clamping plates can clamp it and straighten it, allowing for smooth feeding.

[0017] Meanwhile, the two clamping plates of this utility model can also hold the paper material upright, so that it will not shake during movement and ensure its stability during the rising process. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] As mentioned earlier, existing paper feeding mechanisms generally lack the function of securing the paper stock and pallet. This requires forklifts to precisely transport the pallet along with the paper stock to the designated position. If the pallet and paper stock become misaligned during placement, it can easily cause paper jams, thus affecting the normal operation of the printing process. To address this issue, this invention provides a paper stock securing and adjusting mechanism for printing presses, solving the aforementioned problems. This invention achieves its solution through the following method.

[0029] Example 1:

[0030] Please refer to the instruction manual appendix. Figures 1 to 6 As shown in the figure, this embodiment provides a fixing device for a green and environmentally friendly automatic printing machine. The fixing device includes at least a support plate 1, a base plate 2, a clamping plate 3, and a rotating mechanism 6. The support plate 1 and the base plate 2 are arranged vertically. The support plate 1 has two notches 11, symmetrically arranged. A protrusion 4 is slidably connected within each notch 11, and the protrusion 4 is fixedly connected to the clamping plate 3. The clamping plate 3 is located on the side of the support plate 1 away from the base plate 2. When the protrusion 4 slides within the notch 11, the two clamping plates 3 also move accordingly, sliding on the support plate 1.

[0031] In this first embodiment, as Figure 2 As shown, Figure 2 In order to be in Figure 1 In its initial state, a three-dimensional structural diagram showing the support plate 1 rotated 180° is obtained, allowing the mechanism located between the support plate 1 and the base plate 2 to be displayed. Figure 2 In the aforementioned fixing device, a rotating mechanism 6 is provided to drive the two clamping plates 3 to move. The rotating mechanism 6 includes a first rotating plate 61 and two connecting rods 62. The first rotating plate 61 is rotatably connected to the side of the support plate 1 near the base plate 2, and one end of the connecting rod 62 is rotatably connected to the first rotating plate 61.

[0032] In this first embodiment, as Figure 3 As shown, a drive plate 5 is fixed on one of the protrusions 4, and one end of a connecting rod 62 away from the first rotating plate 61 is rotatably connected to the drive plate 5. The clamping plate 3 with the drive plate 5 is the active clamping plate 3. The other end of the connecting rod 62 away from the first rotating plate 61 is rotatably connected to the protrusion 4, and the clamping plate 3 with the protrusion 4 is the driven clamping plate 3.

[0033] In this first embodiment, as Figure 2 As shown, the drive plate 5 has guide portions 51 at both ends, and two first cylinders 63 are fixed on the support plate 1 at positions corresponding to the guide portions 51. The first cylinders 63 are arranged perpendicular to the clamping plate 3. The output shaft of the first cylinder 63 is fixedly connected to the guide portion 51.

[0034] Therefore, in the specific implementation of this embodiment, the first cylinder 63 drives the extension and retraction, causing the clamping plate 3 to move (i.e., the active clamping plate 3). The active clamping plate 3 causes the protrusion 4 to slide within the notch 11, thereby causing one end of the connecting rod 62 to move accordingly. Correspondingly, the other end of the connecting rod 62 causes the first rotating plate 61 to rotate around its rotation axis, thereby causing the other side of the first rotating plate 61 to rotate. Under the action of another connecting rod 62, the other clamping plate 3 (i.e., the driven clamping plate 3) moves in the opposite direction to the active clamping plate 3 (i.e., the two clamping plates 3 move apart or close to each other). When the operator uses a forklift to place the pallet and paper material on the support plate 1, the above steps can be used to adjust the pallet and paper material that are skewed or not placed in the center of the support plate 1 to the center of the support plate 1 by clamping and adjusting them with the clamping plate 3. This facilitates paper feeding on the printing press and avoids paper jams caused by skewed paper material during the paper feeding process. In addition, the two clamping plates 3 can also clamp the sides of the pallet and paper material (which requires the height of the clamping plates 3 to be compatible with the height of the pallet and paper material) to prevent the pallet and paper material from collapsing due to vibration during the lifting process.

[0035] Example 2:

[0036] Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions therein, this utility model also provides an embodiment two. For example... Figures 1 to 5 As shown in this second embodiment, first guide rods 12 are fixed on both sides of the support plate 1 perpendicular to the two clamping plates 3, and the clamping plates 3 are slidably connected to the first guide rods 12. Furthermore, the surface of the clamping plate 3 near the support plate 1 does not contact the support plate 1, which results in less friction during movement of the clamping plate 3. Also, due to the presence of the first guide rods 12, the two clamping plates 3 will not become stuck in the notch 11 due to uneven force during movement.

[0037] In this second embodiment, as Figure 5 As shown, a second guide rod 64 is also fixedly connected to the support plate 1, and the guide part 51 is slidably connected to the second guide rod 64. This also prevents the guide part 51 and the drive plate 5 from getting stuck during movement.

[0038] Example 3:

[0039] Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions, this utility model also provides a third embodiment. In this third embodiment, a lifting mechanism 7 is provided between the support plate 1 and the substrate 2. When the paper material gradually decreases, the lifting mechanism 7 can drive the support plate 1 to gradually approach the paper feeding mechanism in the printing press, thereby ensuring a sufficient supply of paper material.

[0040] like Figure 1 , Figure 6 As shown, the lifting mechanism 7 includes two X-shaped second rotating plates 75. One end of each second rotating plate 75 is rotatably connected to a second fixed block 72 and a movable block 73, respectively. The other ends of each plate are rotatably mounted on the support plate 1 via a first fixed block 71. The second fixed block 72 is fixed to the base plate 2, and the movable block 73 is driven by a second cylinder 74 to slide on the base plate 2. The second cylinder 74 is fixed to the base plate 2 and is arranged parallel to the clamping plate 3.

[0041] Therefore, in the specific implementation of this third embodiment, the output shaft of the second cylinder 74 is driven to extend and retract, thereby causing the movable block 73 to slide on the base plate 2, thus changing the angle of the second rotating plate 75 connected to it relative to the base plate 2. Then, the first fixed block 71 connected to the second rotating plate 75 will change its distance from the base plate 2, thereby changing the height of the support plate 1 and realizing lifting and lowering.

[0042] Example 4:

[0043] Based on the above embodiments, to further clarify and fully explain the technical solutions, this utility model also provides Embodiment Four. In Embodiment Four, the clamping plate 3 has several grooves on its side near the support plate 1, and several circular steel balls that can roll on the support plate 1 are arranged in these grooves, so that the clamping plate 3 can move on the support plate 1. During the rolling process, the circular steel balls can reduce the friction between the clamping plate 3 and the support plate 1, so as to better achieve the clamping or adjustment of the tray and paper material on the support plate 1.

[0044] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. If such modifications and variations fall within the scope of this utility model and its equivalents, then this utility model also intends to include such modifications and variations.
