Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for a digital printing machine. Background Technology

[0002] The cutting unit of a digital printing press is an important component of the digital printing production line. It is responsible for cutting the printed paper to the specified size. The main function of the cutting unit is to precisely cut the printed paper to meet the customer's requirements for paper size and shape.

[0003] Existing technologies, such as the digital printing machine cutting device described in Chinese Patent No. CN221186786U, include a base plate. A baffle for blocking is fixedly installed on one side of the top of the base plate, and an extension plate for mounting a cylinder is fixedly installed on the other side of the base plate. A material-raising cylinder is fixedly installed on the top of the extension plate, and an L-shaped pusher plate is fixedly installed at the output end of the material-raising cylinder. A cutting component for cutting is fixedly installed on one side of the top of the base plate, and a clamping component for holding materials is fixedly installed on the other side of the top of the base plate. This new invention, through the cooperation between the above structures, only requires the operator to put the paper into the device and remove it after cutting. Compared with traditional large-scale cutting machines, it is convenient, quick, simple, and more practical to operate.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, the aforementioned equipment uses a clamping plate in conjunction with a spring to clamp and fix the paper when cutting it. However, the spring cannot precisely control the clamping force on the paper. Excessive force can easily damage the paper, while insufficient force can easily cause unstable clamping and affect the cutting effect. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing digital printing machine cutting device cannot accurately control the clamping force during use, thus affecting the cutting effect. Therefore, a digital printing machine cutting device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cutting device for a digital printing machine, comprising a collecting mechanism, a fixing mechanism fixedly installed on the top of the collecting mechanism, the fixing mechanism including a support frame, a second hole opened on one side of the outer wall of the support frame, a lead screw movably inserted into the inner surface wall of the second hole, a drive motor provided on one side of the outer wall of the lead screw, a movable slide connected to the outer surface wall of the lead screw, a push plate fixedly installed at the bottom of the movable slide, two hydraulic cylinders fixedly installed on the inner surface wall of the support frame, a piston rod provided at the output end of each of the two hydraulic cylinders, a connecting plate fixedly installed on the outer surface wall of each of the two piston rods, and a set of rollers movably inserted into the inner surface wall of each of the two connecting plates.

[0007] Preferably, two hydraulic cylinders are fixedly installed on the top of the support frame, and piston rods are provided at the output ends of the two hydraulic cylinders. A fixing plate is fixedly installed between the bottoms of the two piston rods.

[0008] Preferably, two hydraulic cylinders are fixedly installed on the top of the support frame, and piston rods are provided at the output ends of the two hydraulic cylinders. A cutting blade is fixedly installed between the bottoms of the two piston rods.

[0009] Preferably, an infrared sensor is fixedly installed at the bottom of the support frame, and a controller is fixedly installed on one side of the outer wall of the support frame.

[0010] Preferably, the collecting mechanism includes a base, four casters are fixedly installed on the bottom of the base, and four fixing rods are fixedly installed on the bottom of the inner wall of the base.

[0011] Preferably, a collection box is provided at the bottom of the inner wall of the base, and four holes are provided at the bottom of the collection box, with the outer walls of the four fixing rods inserted into the inner walls of the four holes.

[0012] Preferably, the top of the base is fixedly connected to the bottom of the support frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, the operation of two hydraulic cylinders drives two sets of rollers to limit and fix the paper, while the rollers do not delay the movement of the paper. Secondly, the drive motor drives the push plate to move the paper in position. At the same time, the infrared sensor can quickly and accurately detect the position, size and edge information of the paper, which helps to reduce cutting errors, improve cutting accuracy and printing quality, and also avoid the cutting knife from causing injury to the workers. Next, the operation of two hydraulic cylinders lowers the fixing plate to fix the paper, which can effectively prevent the paper from shifting during cutting and ensure the accuracy of the cutting position. Finally, the operation of two hydraulic cylinders drives the cutting knife to descend and complete the cutting of the paper.

[0015] In this invention, four casters allow operators to easily move the cutting device to the required position without expending excessive effort and time on transportation, thus improving the flexibility of equipment layout. At the same time, the collection box can quickly collect waste and debris generated during the cutting process, preventing the accumulation of waste in the cutting area and ensuring the smooth progress of the cutting process.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, such as Figures 1-5 As shown, this utility model provides a cutting device for a digital printing machine, including a collecting mechanism 1. A fixing mechanism 2 is fixedly installed on the top of the collecting mechanism 1. The fixing mechanism 2 includes a support frame 201. A hole 202 is opened on one side of the outer wall of the support frame 201. A lead screw 203 is movably inserted into the inner surface of the hole 202. A drive motor 204 is provided on one side of the outer wall of the lead screw 203. A movable slide 205 is threadedly connected to the outer surface of the lead screw 203. A push plate 206 is fixedly installed at the bottom of the movable slide 205. Two hydraulic cylinders 207 are fixedly installed on the inner surface of the support frame 201. A piston rod 208 is provided at the output end of each of the two hydraulic cylinders 207. The outer surface of each piston rod 208 is... A connecting plate 209 is fixedly installed, and a set of rollers 210 are movably inserted into the inner surface of both connecting plates 209. Two hydraulic cylinders 211 are fixedly installed on the top of the support frame 201. Piston rods 212 are provided at the output ends of both hydraulic cylinders 211. A fixing plate 213 is fixedly installed between the bottoms of the two piston rods 212. Two hydraulic cylinders 214 are fixedly installed on the top of the support frame 201. Piston rods 215 are provided at the output ends of both hydraulic cylinders 214. A cutting blade 216 is fixedly installed between the bottoms of the two piston rods 215. An infrared sensor 217 is fixedly installed at the bottom of the support frame 201. A controller 218 is fixedly installed on one side of the outer wall of the support frame 201.

[0026] The overall effect of Embodiment 1 is as follows: First, the simultaneous operation of two hydraulic cylinders 207 causes the two connecting plates 209 to move in opposite directions, ultimately limiting and fixing the paper with two sets of rollers 210. At this time, the two rollers 210 are located on the left and right sides to limit the paper. Second, the operation of the drive motor 204 causes the lead screw 203 to rotate, thereby moving the movable slide 205, which in turn drives the push plate 206 to move, thereby adjusting the position of the paper and allowing the paper to move horizontally. At the same time, the two sets of rollers 210 can... The paper moves smoothly while being stopped. Then, the infrared sensor 217 works with the controller 218 to determine the specific stopping position of the paper, accurately sensing the position and size of the paper to ensure that the cutting blade 216 cuts in the correct position. Next, two hydraulic cylinders 211 drive the fixing plate 213 to descend and press and fix the paper from top to bottom, which can flatten the edges of the paper and prevent it from warping and affecting the cutting accuracy. Finally, two hydraulic cylinders 214 drive the cutting blade 216 to descend and complete the cutting operation of the paper.

[0027] Example 2, as Figures 1-3 As shown, the collection mechanism 1 includes a base 101, four casters 102 are fixedly installed on the bottom of the base 101, four fixing rods 103 are fixedly installed on the bottom of the inner wall of the base 101, a collection box 104 is provided on the bottom of the inner wall of the base 101, four holes 105 are opened on the bottom of the collection box 104, and the outer walls of the four fixing rods 103 are inserted into the inner walls of the four holes 105. The top of the base 101 is fixedly connected to the bottom of the support frame 201.

[0028] The overall effect of Embodiment 2 is that, when the device is in normal use, the four casters 102 can reduce the labor required for workers to move the device. Workers can move the device quickly by simply pushing or pulling it. Secondly, the collection box 104 is fixed on the base 101 by the outer walls of the four fixing rods 103 being inserted into the inner walls of the four holes 105. The collection box 104 makes waste disposal simpler and more convenient. Workers only need to empty or dispose of the waste in the collection box 104 periodically, without having to perform tedious waste sorting and cleaning work.

[0029] Among them, the drive motor 204, hydraulic cylinder one 207, hydraulic cylinder two 211, hydraulic cylinder three 214, infrared sensor 217 and controller 218 are all existing technologies, and their components and operating principles are all publicly available technologies, which will not be explained in detail here.

[0030] Working principle: First, when the device is in normal use, the base 101 is fixedly connected to four casters 102. These casters allow the cutting device to move easily without relying on complex handling tools or manpower. Next, the paper to be cut is placed on top of the base 101. At this time, two hydraulic cylinders 207 are connected to two piston rods 208, and the two piston rods 208 are also fixedly connected to two connecting plates 209. Simultaneously, a set of rollers 210 are movably inserted into the inner surface of each connecting plate 209. When the two hydraulic cylinders 207 operate simultaneously, they drive the two piston rods 208 to extend and retract, ultimately driving the two... Rollers 210 move in opposite directions to clamp the paper. Next, drive motor 204 is threadedly connected to lead screw 203, and a movable slide 205 is threadedly connected to the outer wall of lead screw 203. A push plate 206 is fixedly installed at the bottom of the movable slide 205. When drive motor 204 operates, it drives lead screw 203 to rotate, allowing the movable slide 205 to move on the outer wall of lead screw 203. This ultimately drives push plate 206 to move, horizontally pushing the paper. Simultaneously, while the paper is being pushed, the two sets of rollers 210 limit and fix the paper from both sides, and the rotation of the rollers 210 does not hinder the paper's movement. The infrared sensor 217, in conjunction with the controller 218, can stop the drive motor 204 when the paper moves to the bottom of the cutter 216, ensuring the paper is positioned below the cutter 216. The infrared sensor 217 accurately detects the paper's position and size, ensuring the cutter 216 cuts in the correct position, helping to reduce cutting errors and improve cutting accuracy and print quality. Secondly, the operation of the two hydraulic cylinders 211 drives the extension and retraction of the two piston rods 212, thereby lowering the fixing plate 213. This allows the fixing plate 213 to press and hold the paper from above, ensuring the paper remains stable during the cutting process and preventing... To prevent the paper from moving or deforming due to external forces, two hydraulic cylinders 214 operate to drive two piston rods 215 to extend and retract, ultimately driving the cutting blade 216 to descend vertically from top to bottom to complete the cutting operation. The waste paper generated after cutting will fall into the collection box 104, so that the waste and debris generated during the cutting process can be collected and processed in a timely manner, avoiding the scattering and flying of waste. The outer walls of the four fixing rods 103 of the collection box 104 are inserted into the inner walls of the four holes 105, which can play a fixing role, making the placement of the collection box 104 more stable and facilitating the unified processing of waste by the staff.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
