Description

Technical Field

[0001] This utility model relates to the technical field of PS board processing equipment in the printing industry, specifically a PS board pre-printing positioning and forming equipment. Background Technology

[0002] PS plates, short for pre-coated photosensitive plates, consist of a substrate and a photosensitive layer. The substrate is usually an aluminum substrate, and the photosensitive layer is formed by coating the substrate with a photosensitive liquid. PS plates for printing have the following characteristics:

[0003] High resolution: fine mesh, smooth and complete dots, good color reproduction, and high image clarity.

[0004] Abrasion resistance and acid resistance: Diazo photosensitive resin has good abrasion resistance and acid resistance. After high-temperature baking, the photosensitive film is enamelized, the hardness of the printing plate increases, and the printing durability can reach 200,000 to 300,000 sheets.

[0005] Hydrophilicity and oleophilicity: The hydrophilic part is an aluminum oxide film, which has good hydrophilicity, wear resistance and chemical stability; the oleophilic part is a diazo photosensitive resin with a high substrate plane, which has good oleophilic and hydrophobic properties.

[0006] PS plates are widely used in offset printing and are used in conjunction with electronic typesetting, electronic color separation, and multicolor offset printing, making them the mainstream plate-making system today. PS plates require positioning adjustments during the printing and packaging process.

[0007] A prior art application (application number 202120741775.X) describes a punching device for easily positioned printing plates, comprising a base. After the printing plate is placed on top of the punching plate, a bidirectional motor drives a threaded rod to rotate, thereby rotating a folding plate and a clamping plate through a rotating column to clamp the printing plate. This prevents the printing plate from sliding or shifting during the punching process, thus positioning the printing plate and improving the punching accuracy. However, it cannot perform multi-point liquid addition to adjust the pH value, and it is not convenient for positioning and bending the PS plate before printing, thus affecting the efficiency of PS plate printing. Utility Model Content

[0008] The purpose of this invention is to provide a pre-printing positioning and forming equipment for PS boards, so as to solve the problem in the prior art that it is inconvenient to perform positioning and bending processing on PS boards before printing, thereby affecting the efficiency of PS board printing.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a PS board printing pre-process positioning and forming equipment, including a lower machine base, wherein a first slider and a second slider are provided inside the lower machine base via a lead screw threaded in opposite directions, a platform is provided on the upper side of both the first slider and the second slider, an upper support is provided on the upper side of the platform, and an upper pressure plate is provided inside the upper support via a first cylinder, and a bending plate is provided on the lower side of one end of the upper pressure plate via a second cylinder, and end positioning mechanisms are also provided on the upper sides of both ends of the lower machine base.

[0010] Furthermore, the end positioning mechanism includes an end limiting plate provided by a third cylinder, and the third cylinder and the end limiting plate are symmetrically arranged about the lower base.

[0011] Furthermore, the lower end of the end limiting plate is provided with first guide rods on both sides, and the first guide rods are slidably arranged with the guide grooves at both ends of the lower base.

[0012] Furthermore, a limiting sliding hole is provided on the inner side of the upper part of the lower base, and a vertical rod that slides between the first slider and the platform is provided and is slidably configured with the limiting sliding hole.

[0013] Furthermore, the lead screw includes a lead rod rotatably disposed in the middle of the lower machine base, with two opposite sets of external threads on the outer sides of both ends of the lead rod, and a servo motor is driven to one end of the lead rod. The lower machine base also has a second guide rod slidably connected to the first slider and the second slider.

[0014] Furthermore, a heating layer is provided on the lower end side of the upper pressure plate, and the heating layer is an electrothermal layer. A third guide rod is provided on the upper side of both ends of the upper pressure plate.

[0015] Furthermore, the lower end of the upper pressure plate is provided with a groove, and the bending plate is completely retracted into the groove when not in use.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention involves placing a PS board to be bent and positioned flat on two platforms. A first cylinder drives an upper pressure plate to move down and press it onto the upper sides of both ends of the PS board for positioning, while preventing the ends of the PS board from moving during bending. Then, a second cylinder drives a bending plate to move down and bend the ends of the PS board at a 90-degree angle, thus achieving positioning and bending of the PS board before printing. The invention is simple in structure and easy to operate.

[0018] Furthermore, the lower base is provided with an end positioning mechanism on the upper side of both ends. The end positioning mechanism includes an end limiting plate provided by a third cylinder. The third cylinder and the end limiting plate are symmetrically arranged about the lower base, so that the end limiting plate is driven by the third cylinder to move closer to the PS plate, thereby clamping and fixing both ends of the PS plate, which further improves the positioning stability of the PS plate.

[0019] In this invention, the lower base is provided with a first slider and a second slider via opposing threads of a lead screw. Both the first slider and the second slider are provided with a platform on their upper sides. The lead screw includes a screw rod rotatably disposed in the middle of the lower base. The outer sides of both ends of the screw rod are provided with two sets of opposite external threads, and one end of the screw rod is connected to a servo motor for transmission. This allows the first slider and the second slider to be moved in opposite directions by the lead screw for adjustment, thereby adjusting the distance between the two platforms and thus adjusting the bending position of both ends of the PS board.

Moreover, the structure is simple and the operation is convenient.

[0027] like Figure 1 and Figure 2 As shown, in order to improve the stability of PS board positioning, an end positioning mechanism is also provided on the upper side of both ends of the lower base 1.
