Description

Technical Field

[0001] This utility model relates to the field of packaging material cutting technology, and in particular to a tool for precisely cutting packaging materials. Background Technology

[0002] Packaging materials refer to materials used to wrap and protect products. The most basic type is paper, which is easy to recycle and reuse. After cutting, check whether the packaging material has rough edges, tears, dents, or non-perpendicular edges. This will help determine whether there will be air leakage or whether the seam will come unglued during subsequent packaging.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Most existing packaging material cutting tools have a fixing mechanism, a cutting tool, and a power mechanism. The existing fixing mechanism fixes the cardboard, usually the whole cardboard, and then a single cutting tool cuts and samples one by one. During cutting, the cutting tool is often far from the fixing mechanism, which causes the support plate under the cutting tool to warp. This often results in the edges of the cut cardboard not being perpendicular, leading to inaccurate sampling. At the same time, most existing tools require manual labor, with the cutting tool used in conjunction with manual cutting to cut and sample different parts of the cardboard. This manual and tool approach has certain inaccuracies and is labor-intensive.

[0004] Therefore, those skilled in the art have provided a tool for precisely cutting packaging materials to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tool for precisely cutting packaging materials. The cutting mechanism provides stability for the cardboard during cutting, while the moving mechanism enables cutting at different positions, saving manpower and achieving high precision. Furthermore, the combination of the two structures allows for the simultaneous cutting of samples at four different positions, resulting in high efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tool for precisely cutting packaging materials, comprising a cutting mechanism and a moving mechanism. The cutting mechanism includes a bracket, two large card frames, and two U-shaped frames. An electric push rod is fixedly connected to the inner wall of the top center of the two large card frames. A connecting block is fixedly connected to the output end of the two electric push rods. Two cutters are fixedly connected to the outer wall of each of the two connecting blocks. Multiple pressure plates are fixedly connected to the bottom of each of the two U-shaped frames. The moving mechanism includes a screw, a fixing block is threaded to the outer wall of the screw, a third electric push rod is fixedly connected to the inner wall of the fixing block, and a ring is fixedly connected to the output end and the rear end of the third electric push rod, and a second electric push rod is fixedly connected to the inner wall of the two rings.

[0007] Furthermore, each of the two output ends of the second electric push rod is fixedly connected to a small card frame, and the bottom of each of the two small card frames is fixedly connected to the center of the top of the two large card frames.

[0008] Furthermore, the bottoms of the two large card frames are fixedly connected to the tops of the two loop-shaped frames.

[0009] Furthermore, a servo motor is fixedly connected to the inner wall of one side of the bracket near the top. The output end of the servo motor is fixedly connected to the end of the screw near the servo motor. The end of the screw away from the servo motor is rotatably mounted on the inner wall of the bracket away from the servo motor near the top.

[0010] Furthermore, the bottom of the fixing block is slidably disposed on the inner wall of the top of the bracket.

[0011] Furthermore, a base plate is fixedly connected to the inner wall of the bracket near the bottom, and a gasket is fixedly connected to the top of the base plate.

[0012] Furthermore, a controller is fixedly connected to the outer wall of the bracket near the servo motor and near the bottom, and a synchronization controller is fixedly connected to the outer wall of the bracket away from the servo motor and near the bottom.

[0013] This utility model has the following beneficial effects: 1. This utility model proposes a tool for precisely cutting packaging materials. The cardboard is placed on top of a pad. Two No. 2 electric push rods push two small card frames, two large card frames, and the No. 1 electric push rods on the inner walls of the two large card frames to move down. At the same time as the two large card frames move down, two U-shaped frames and multiple pressure plates move down to fix the cardboard. The two No. 1 electric push rods push two connecting blocks to move down. The movement of the two connecting blocks further moves the cutters on both sides down to cut the cardboard. Four samples can be cut at a time. The multiple pressure plates are set around the cutters to ensure that the cardboard is more stable when the cutters cut the cardboard, thus ensuring the cutting quality.

[0014] 2. This utility model proposes a tool for precisely cutting packaging materials. When cutting at different positions, the No. 3 electric push rod drives multiple pressure plates, including the front-end ring, the No. 2 electric push rod, the small card frame, the large card frame, and the U-shaped frame, to move forward. Simultaneously, the large card frame moves forward, causing the No. 1 electric push rod, the connecting block, and the two cutters on the inner wall to move forward. Adjusting the distance between them, the servo motor causes the screw to rotate along the inner wall of the top of the support. The screw causes the fixing block to move left and right. The fixing block causes the No. 3 electric push rod, the two rings, the two No. 2 electric push rods, the small card frame, the large card frame, the U-shaped frame, the multiple pressure plates, the No. 1 electric push rod, and the cutters to move left and right, adjusting the position of the cardboard to be cut. This mechanism can cut cardboard at different positions, and its mechanized design offers higher precision and more stable quality compared to manual cutting. Furthermore, in conjunction with the cutting mechanism, only one cut is needed to cut samples at four different positions. Attached Figure Description

[0017] 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.

[0018] Reference Figures 1-4 This utility model provides an embodiment of a tool for precisely cutting packaging materials, including a cutting mechanism 1 and a moving mechanism 2. The cutting mechanism 1 includes a bracket 101, two large card frames 103, and two U-shaped frames 104. A first electric push rod 107 is fixedly connected to the inner wall of the top center of the two large card frames 103. A connecting block 108 is fixedly connected to the output end of the two first electric push rods 107. Two cutters 106 are fixedly connected to the outer wall of each of the two connecting blocks 108. Multiple pressure plates 105 are fixedly connected to the bottom of each of the two U-shaped frames 104. The moving mechanism 2 includes a screw 201. A fixing block 203 is threadedly connected to the outer wall of the screw 201. A third electric push rod 205 is fixedly connected to the inner wall of the fixing block 203. A ring 204 is fixedly connected to the output end and the rear end of the third electric push rod 205. A second electric push rod 202 is fixedly connected to the inner wall of the two rings 204.

[0019] Specifically, the cardboard is placed on top of the pad. Two second-generation electric push rods 202 drive two small card frames 102 downwards. The two small card frames 102 cause two large card frames 103, two first-generation electric push rods 107, and the cutter 106 to move downwards. The two large card frames 103 drive two U-shaped frames 104 and multiple pressure plates 105 downwards to fix the area around the cardboard to be cut. Then, the two first-generation electric push rods 107 push two connecting blocks 108 downwards, and the multiple cutters 106 move downwards to cut. This application can cut four samples at once, all of which are different shapes and cutting patterns, which can make subsequent data more accurate. The multiple pressure plates 105 fix the area around the cutter 106, which can ensure the stability of the area around the cutting part during cutting. When cutting at different positions, the third-generation electric push rod 205 pushes the front ring 204 and the second-generation electric push rod 106 to move downwards. The push rod 202 moves forward, and the second electric push rod 202 then drives the small clamping frame 102, the large clamping frame 103, the U-shaped frame 104, and multiple pressure plates 105 to move forward. The large clamping frame 103 causes the first electric push rod 107 and the two cutters 106 to move forward, adjusting the distance to the above structures at the rear end. The servo motor 206 causes the screw 201 to rotate, and the screw 201 causes the fixing block 203 to move left and right along the groove on the inner wall of the top of the bracket 101. When the fixing block 203 moves, it causes the third electric push rod 205 to move left and right. The third electric push rod 205 then causes the two rings 204, the two second electric push rods 202, the two small clamping frames 102, the two large clamping frames 103, the first electric push rod 107, and the cutters 106 to move left and right, adjusting different cutting positions. The entire process adopts a mechanized design, saving manpower and making it more precise.

[0020] Reference Figures 1-4 Two electric push rods 202 are fixedly connected to small card frames 102 at their output ends. The bottom of each small card frame 102 is fixedly connected to the center of the top of each of the two large card frames 103. The bottom of each large card frame 103 is fixedly connected to the top of each of the two loop frames 104. A servo motor 206 is fixedly connected to the inner wall of one side of the bracket 101 near the top. The output end of the servo motor 206 is fixedly connected to the end of the screw 201 near the servo motor 206. The end of the screw 201 away from the servo motor 206 is rotatably mounted on the inner wall of the bracket 101 away from the servo motor 206 near the top. The bottom of the fixing block 203 is slidably mounted on the inner wall of the top of the bracket 101. A base plate is fixedly connected to the inner wall of the bracket 101 near the bottom, and a gasket is fixedly connected to the top of the base plate. A controller is fixedly connected to the outer wall of the bracket 101 near the servo motor 206 and near the bottom. A synchronization controller is fixedly connected to the outer wall of the bracket 101 away from the servo motor 206 and near the bottom.

[0021] Specifically, the servo motor 206 can ensure that its output end will not rotate after it stops working, thus being locked and preventing the screw 201 from rotating arbitrarily. This is existing public technology and will not be elaborated here. The servo motor 206 and the top of one side of the bracket 101 together provide support for the screw 201. The gasket is made of rubber and needs to be replaced after use. The controller can control the electrical equipment in this application. The synchronous controller can make the two second electric push rods 202 work simultaneously and the two first electric push rods 107 work simultaneously. The synchronous controller collects parameters through internal displacement sensors, encoders, and pressure sensors, calculates the deviation between the two components, and then drives the power mechanism to make adjustments. This is the general working principle of the synchronous controller, which should be common knowledge familiar to those skilled in the art and will not be elaborated here.

[0022] Working principle: The cardboard is placed on top of the pad. Then, the controller sends an electrical signal to move two No. 2 electric push rods 202 downward, pushing two small card frames 102 downward. The two small card frames 102 drive the two large card frames 103 and the No. 1 electric push rod 107 on the inner wall to move downward. The two large card frames 103 cause the two U-shaped frames 104 and multiple pressure plates 105 on their outer walls to move downward, fixing the cardboard. After the multiple pressure plates 105 fix the cardboard, the controller sends an electrical signal to push the output ends of the two No. 1 electric push rods 107 to push the two connecting blocks 108 downward. The two connecting blocks 108 then push the cutters 106 on both sides downward to cut the cardboard. Four samples can be cut at a time. Secondly, when cutting at different positions is required, the controller can send an electrical signal to start the No. 3 electric push rod 205. The output end of the No. 3 electric push rod 205 pushes the front ring 204, the No. 2 electric push rod 202, the small card frame 102 and the large card frame 103, the U-shaped frame 104 and multiple pressure plates 105 forward. At the same time, the large card frame 103 drives the No. 1 electric push rod 107 and the two cutters 106 on the inner wall to move forward. The controller can also send an electrical signal to start the servo motor 206, which drives the screw 201 to rotate. The screw 201 causes the fixing block 203 to move left and right along the groove on the inner wall of the top of the bracket 101. The fixing block 203 drives the No. 3 electric push rod 205, the two rings 204, the two No. 2 electric push rods 202, the small card frame 102, the No. 1 electric push rod 107 and the cutter 106 on the inner wall to move left and right, adjust their positions and cut the cardboard at different positions.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
