Description

Technical Field

[0001] The utility model relates to the technical field of label cutting, in particular to a fine-adjustable label cutting device. Background Art

[0002] Most of the labels in the printing industry are printed materials used to identify the relevant instructions of their products, and most of them have adhesive on the back. However, there are also some labels that are not adhesive when printed, which can also be called labels. Labels with adhesive are commonly known as self-adhesive labels. In the production process of labels, a cutting mechanism is needed to cut the labels for subsequent storage and sales.

[0003] For example, the utility model with application number 202022555670.3 discloses a cutting mechanism for a label paper die-cutter. The cutting mechanism of the label paper die-cutter is provided with a pressing device located outside the cutter head. When the fixed block moves downward with the cutter head, the pressing block first contacts the paper and is pressed on the paper under the action of the spring and the slide rod. The cutter head cuts the paper inside the opening, which solves the problem that the existing cutting mechanism has no fixing device for the paper, resulting in uneven label paper. However, similar to the cutting device in the above-mentioned document, although the fixed block is used to fix the label paper to avoid the problem of uneven cutting, it is considered that the label paper will be squeezed back and forth during the transportation process, resulting in unevenness. Even if the label paper tape is pressed on the side during the cutting process, the flatness of the paper tape in the cut area cannot be effectively guaranteed, and there is no structural assistance that can be flexibly fine-tuned to adjust the flatness of the label tape.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a fine-tunable label cutting device is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a fine-adjustable label cutting device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fine-adjustable label cutting device, comprising a base and a tensioning frame group, a cutting mechanism is installed in the middle of the base, and limit frames are arranged on both sides of the cutting mechanism, and a belt conveyor is arranged at the bottom of the cutting mechanism, a feeding roller is arranged on one side of the base, the tensioning frame group is arranged on the side of the feeding roller close to the cutting mechanism, and an electric winding roller is arranged on the side of the base away from the feeding roller, the tensioning frame group comprises a moving frame, a tensioning roller, a screw rod, a servo motor and a fixed frame, a tensioning roller is arranged at the bottom of the moving frame, and screw rods are vertically installed on the left and right sides of the moving frame, and a servo motor is installed on the top of the screw rod through a coupling, and a fixed frame is vertically installed on one side of the servo motor.

[0007] Furthermore, the cutting mechanism includes a cutting table, a cutting template, a stabilizing frame and a punching cylinder. The cutting template is installed on the top surface of the cutting table, and a stabilizing frame is installed on the top of the cutting table, and punching cylinders are vertically installed on both sides of the top of the stabilizing frame.

[0008] Furthermore, the cutting template is connected to the cutting table through a bolt structure, and a through-opening structure is provided in the middle of the cutting table, and a belt conveyor is arranged in the middle of the bottom of the cutting table.

[0009] Furthermore, the cutting mechanism also includes a cutting tool, a fixed rod and a push plate. The bottom output end of the stamping cylinder is connected to the cutting tool, and the inside of the cutting tool is penetrated by the fixed rod, and the bottom of the fixed rod is horizontally connected to the push plate.

[0010] Furthermore, the punching cylinder is arranged on the left and right sides of the cutting tool, and the top of the fixed rod is fixedly connected to the stabilizing frame, and the fixed rod and the cutting tool are slidably connected, and the push plate is arranged inside the cutting tool.

[0011] Furthermore, the limiting frame includes a pressure rod, a bearing frame and a telescopic rod. The left and right ends of the pressure rod are both equipped with bearing frames, and the bottom of the bearing frame is vertically equipped with a telescopic rod.

[0012] Furthermore, the telescopic rod is used to vertically adjust the setting height of the pressure rod, and the limiting frame is arranged on the left and right sides of the cutting mechanism.

[0013] Furthermore, the movable frame and the tensioning roller are parallel to each other, and the movable frame is threadedly connected to the lead screw.

[0014] The utility model provides a fine-adjustable label cutting device, which has the following beneficial effects:

[0015] 1. The utility model starts the servo motor on the top of the fixed frame. With the drive of the servo motor, the screw connected to the power output end at its bottom will rotate axially in the vertical direction. At this time, the movable frame threadedly connected to the surface of the screw will drive the tensioning roller at its bottom to perform slight up and down translation in the vertical direction. At the same time, under the structural extension of the telescopic rod, the pressure rod connected to it through the bearing frame at the top can also translate up and down in the vertical direction. By using the cooperative use of the above structure, on the one hand, the device structure has flexible structural adjustability, so that the corresponding structural adjustment can be made according to the needs of the operation to achieve the best processing effect. On the other hand, the use of the above structure can ensure that the label tape provides a tensioning effect to the greatest extent during the transportation process to ensure the overall flatness of the label tape, and at the same time ensure that the label tape can be as closely attached to the surface of the cutting template as possible to ensure that the cutting tool can cut accurately and avoid the problem of material loss caused by cutting offset.

[0016] 2. The utility model has a fixing rod vertically installed at the middle of the top of the stabilizing frame, and the fixing rod is passed through the inside of the cutting tool. At the same time, a push plate is installed at the bottom of the fixing rod, so that when the punching oil cylinder is telescopically driven in the vertical direction and drives the cutting tool connected thereto to operate synchronously, the label tape is cut as the cutting tool is pushed down. Since the structure of the fixing rod is fixed, the cutting operation will not be affected at this time. As the punching oil cylinder drives the cutting tool structure to reset, the push plate at the bottom of the fixing rod will continue to twist and move relatively inside the cutting tool, so as to avoid being cut. The cut labels are stuck inside the cutting tools so that the cut labels can directly pass through the hollow structure in the middle of the cutting table and the cutting template and fall to the surface of the belt conveyor at the bottom, thereby transporting the cut labels to the downstream equipment. By using the above structure, the operational flexibility and convenience of the cutting equipment can be ensured as much as possible, while preventing material jamming and ensuring the accuracy of cutting as much as possible. In addition, according to the needs of cutting, the cutting template installed on the surface of the cutting table using a bolt structure can also be flexibly replaced to make subtle adjustments to cooperate with the cutting process.

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

The left and right ends of the pressure rod 301 are equipped with bearing frames 302, and the bottom of the bearing frame 302 is vertically equipped with a telescopic rod 303. The telescopic rod 303 is used to vertically adjust the setting height of the pressure rod 301. The limiting frame 3 is arranged on the left and right sides of the cutting mechanism 2. By starting the servo motor 604 on the top of the fixed frame 605, as the servo motor 604 is driven, the screw rod 603 connected to the power output end at its bottom will perform axial rotation in the vertical direction. At this time, the movable frame 601 threadedly connected to the surface of the screw rod 603 will drive the tensioning roller 602 at its bottom to perform slight up and down translation in the vertical direction. At the same time, under the structural extension and contraction of the telescopic rod 303, the pressure rod 301 connected to it at the top through the bearing frame 302 can also perform up and down translation in the vertical direction.

[0024] like Figures 1 to 4 As shown, the cutting mechanism 2 includes a cutting table 201, a cutting template 202, a stabilizing frame 203 and a punching cylinder 204. The cutting template 202 is installed on the top surface of the cutting table 201, and the stabilizing frame 203 is installed on the top of the cutting table 201. The punching cylinders 204 are vertically installed on both sides of the top of the stabilizing frame 203. The cutting template 202 is connected to the cutting table 201 through a bolt structure, and a through-hole structure is opened in the middle of the cutting table 201, and the belt conveyor 4 is arranged in the middle of the bottom of the cutting table 201. The cutting mechanism 2 also includes a cutting tool 205, a fixing rod 206 and a push plate 207. The bottom output end of the punching cylinder 204 is connected to the cutting tool 205, and the interior of the cutting tool 205 is penetrated by the fixing rod 206, and the bottom of the fixing rod 206 is horizontally connected to the push plate 207. 07.

When the punching cylinder 204 is telescopically driven in the vertical direction and drives the cutting tool 205 connected thereto to operate synchronously, at this time, as the cutting tool 205 is pushed down to cut the label tape, since the structure of the fixed rod 206 is fixed, the cutting operation will not be affected at this time. As the punching cylinder 204 drives the structure of the cutting tool 205 to reset, the push plate 207 at the bottom of the fixed rod 206 will continue to twist and move relatively inside the cutting tool 205, so as to avoid the cut label being stuck inside the cutting tool 205.

[0025] In summary, if Figures 1 to 4 As shown, when the fine-adjustable label cutting device is used, firstly, the label roll to be cut is installed in the middle of the feeding roller 5 on one side of the base 1, and then one end of the label tape is passed between the moving frame 601 and the tensioning roller 602, and then it is passed around the bottom of the limiting frame 3 on one side of the cutting mechanism 2 from top to bottom, and then the label tape is passed horizontally from above the cutting template 202 on the top surface of the cutting table 201, and then it is passed again from below the limiting frame 3 on the other side of the cutting mechanism 2, and finally it is wound from bottom to top on the surface of the electric winding roller 7;

[0026] Afterwards, the limiting frames 3 on both sides of the cutting mechanism 2 start to operate. Under the extension and retraction of the telescopic rod 303, the pressure rod 301 connected to the top through the bearing frame 302 will be synchronously handled and translated, so that the label tape is pressed down to the surface of the cutting template 202. At the same time, the servo motor 604 at the top of the fixed frame 605 will start to operate, driving the screw rod 603 connected to the bottom to rotate axially, thereby driving the mobile frame 601 connected to the screw rod 603 and the tensioning roller 602 at the bottom of the mobile frame 601 to appropriately translate up and down in the vertical direction, thereby realizing fine adjustment of the tensioning of the label tape;

[0027] Then, with the operation of the punching cylinders 204 on both sides of the stabilizing frame 203, the cutting tool 205 connected at its lower end will be driven to move vertically downward rapidly and quickly cut the label tape on the surface of the cutting template 202. Then, driven by the structure of the punching cylinder 204, the cutting template 202 will be structurally reset. At this time, the push plate 207 at the bottom of the fixed rod 206 statically placed inside the cutting template 202 will push the label cut inside the cutting tool 205 out of the cutting tool 205, so that it falls from the opening between the cutting template 202 and the cutting table 201 to the surface of the belt conveyor 4 at the bottom of the entire cutting mechanism 2, and the belt conveyor 4 is used to transport the cut labels to the downstream equipment for further processing.
