Description

Technical Field

[0001] The invention belongs to the technical field of label cutting equipment and relates to a material pressing upper die seat used in label cutting equipment. Background Art

[0002] In the field of label cutters, traditional upper die blocks generally utilize a single-point drive system. This design typically installs a single drive unit at the center of the upper die block's top plate. This drive is transmitted to the upper die block's lift plate via a connecting rod or transmission mechanism, driving the cutter for vertical cutting.

[0003] However, this single-point drive method can easily lead to uneven force on the upper die lift plate during the cutting process because the driving force is concentrated in the center. This can cause overall deformation of the die, offset the cutting tool path, and cause quality problems such as burrs on the label edges and dimensional errors, seriously affecting product qualification rates. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A pressing upper die base used in label cutting equipment, comprising: an upper die base top plate, an upper die base lifting plate and an upper die base rotating plate;

[0006] The upper die base lifting plate is arranged at the lower end of the upper die base top plate, and the upper die base rotating plate is rotatably mounted at the lower end of the upper die base lifting plate;

[0007] Four groups of driving modules are installed on the top plate of the upper die base to drive the upper die base lifting plate to move up and down in the vertical direction. The rectangular array of each group of driving modules is arranged at the upper end position of the upper die base lifting plate; the driving structure of each group of driving modules is respectively connected to each corner position of the upper die base lifting plate.

[0008] As a further solution of the present invention: the driving module is located at the four corners of the upper die base top plate, which includes: a driving motor, a reducer, a transmission screw and a screw sleeve;

[0009] The drive motor and reducer are both installed on the upper end surface of the upper die base top plate, the screw sleeve is installed in the upper die base top plate, the upper end of the transmission screw is matched with the reducer, and the lower end passes through the screw sleeve and abuts against the corner position of the upper die base lifting plate;

[0010] In addition, a plurality of lifting spring guide columns are arranged between the upper die base top plate and the upper die base lifting plate, and a corresponding number of lifting sinker through holes are arranged on the upper die base top plate. The upper ends of the lifting spring guide columns and the springs are located in the lifting sinker through holes and are clearance-matched with them; the lower ends of the lifting spring guide columns pass through the lifting sinker through holes and are fixedly connected to the upper die base lifting plate.

[0011] As a further solution of the present invention: a height-adjusting seat plate is further provided on the top plate of the upper die seat, and a height-adjusting guide rail arranged vertically is provided on the height-adjusting seat plate; the driving module is installed on the height-adjusting guide rail through a slide.

[0012] As a further solution of the present invention: a rotating spring guide column is arranged between the upper die base rotating plate and the upper die base lifting plate; a rotating countersunk through hole is arranged at the center position of the upper die base lifting plate, and the upper end of the rotating spring guide column is located in the rotating countersunk through hole and is loosely matched with it; the lower end of the rotating spring guide column passes through the rotating countersunk through hole and is fixedly connected to the upper die base rotating plate.

[0013] As a further solution of the present invention: two sets of adjustment limit mechanisms are arranged on the end surface of one side of the upper mold base lifting plate, which include: an adjustment nut seat fixedly installed on the upper mold base lifting plate and an adjustment screw installed on the adjustment nut seat; the end of the adjustment screw is against the side end surface of the upper mold base rotating plate.

[0014] As a further solution of the present invention: the upper end surface of the upper die seat lifting plate is further provided with a plurality of rotary guide mechanisms, which include: a guide screw, a limit cross bar and a guide pulley;

[0015] A through guide slot is also provided on the upper end surface of the upper die seat lifting plate, and the guide slot is an arc-shaped structure as a whole;

[0016] The lower end of the guide screw passes through the guide slot and is fixedly connected to the upper die base rotating plate, and the length of the guide slot corresponds to the adjustable angle of the upper die base rotating plate;

[0017] The limiting cross bar is installed on the upper end of the guide screw and is distributed vertically therewith; guide pulleys are installed at both ends of the limiting cross bar.

[0018] The beneficial effects of this invention are: through the rectangular array arrangement of four drive modules, the working effect of surface-driven downward pressure is achieved; compared with the traditional single-point drive method, this structure has four servo systems to adjust the pressure, which can realize intelligent operation and reduce the technical requirements of the operator of existing equipment; it greatly simplifies the difficulty of die cutting operation. The pressure of the four corners can be adjusted independently, and the pressure of the four sides can be adjusted independently; the overall pressure can be increased or decreased with one button. The high degree of intelligence solves the problem that the old equipment cannot adjust the pressure of the single point of the mold;

[0019] It effectively avoids mold distortion caused by uneven force, ensures the accuracy of the tool's vertical cutting trajectory, and the collaborative operation of multiple drive points disperses the load of a single component, reduces the wear rate of the drive module and transmission structure, and reduces maintenance frequency and cost; and the stable surface drive mode ensures constant force on the tool during the cutting process. Even in high-load conditions such as multi-layer label stacking, it can still maintain efficient and stable cutting quality, greatly improving the production efficiency and reliability of the label cutter, and providing strong support for high-precision, large-scale label cutting operations.

For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0029] The present invention provides Figures 1 to 5 In an embodiment of the present invention, a pressing upper die base used in a label cutting device includes: an upper die base top plate 1, an upper die base lifting plate 2, and an upper die base rotating plate 3;

[0030] The upper die base lifting plate 2 is arranged at the lower end of the upper die base top plate 1, and the upper die base rotating plate 3 is rotatably mounted at the lower end of the upper die base lifting plate 2 for installing the tool. During operation, the angle of the tool can be adjusted by rotating the upper die base rotating plate 3 to meet different usage requirements.

[0031] Four sets of drive modules 4 are installed on the upper die base top plate 1 to drive the upper die base lifting plate 2 to move vertically up and down. Each set of drive modules 4 is arranged in a rectangular array at the upper end of the upper die base lifting plate 2. The drive structure of each set of drive modules 4 is connected to each corner of the upper die base lifting plate 2. When working, the four sets of drive modules 4 operate synchronously, driving the upper die base lifting plate 2 to descend smoothly through the fulcrum points at the corners. Compared with the traditional single-point drive, this structural design can achieve the working effect of surface-driven downward pressure through the effect of uniform downward pressure on the four corners, ensuring that the tool cuts the product evenly, greatly reducing the risk of mold deformation due to uneven force, and significantly improving processing accuracy and product yield.

[0032] Furthermore, the driving module 4 is located at the four corners of the upper die base top plate 1, and includes: a driving motor 41, a reducer 42, a transmission screw 43 and a screw sleeve 44;

[0033] The driving motor 41 and the reducer 42 are both installed on the upper end surface of the upper die base top plate 1, and the screw sleeve 44 is installed in the upper die base top plate 1. The upper end of the transmission screw 43 is in transmission cooperation with the reducer 42, and the lower end passes through the screw sleeve 44 and abuts against the corner position of the upper die base lifting plate 2 (serving as the driving structure of the driving module 4); during the operation, the driving motors 41 of each group of driving modules 4 work synchronously, and the rotational power output of the driving motor 41 is converted into the linear motion of the transmission screw 43 through the reducer 42; thereby driving the upper die base lifting plate 2 downward to achieve work;

[0034] In addition, a plurality of lifting spring guide columns 5 are arranged between the upper die base top plate 1 and the upper die base lifting plate 2, and a corresponding number of lifting sinker through holes 13 are provided on the upper die base top plate 1. The upper end of the lifting spring guide column 5 and the spring are located in the lifting sinker through hole 13 and are clearance-matched with it; the lower end of the lifting spring guide column 5 passes through the lifting sinker through hole 13 and is fixedly connected with the upper die base lifting plate 2; the upper die base lifting plate 2 is connected to the upper die base top plate 1, while ensuring the vertical freedom of the upper die base lifting plate 2; and in the process of the upper die base lifting plate 2 descending, the spring assembly in the lifting spring guide column 5 will be compressed by force, and when the transmission screw 43 is reset upward, the spring assembly of the lifting spring guide column 5 rebounds, causing the upper die base lifting plate 2 to move upward and reset, thereby completing a lifting working cycle of the upper die base lifting plate 2, and working back and forth in this way, cooperating with the lower die base structure to realize label cutting.

[0035] Furthermore, a height-adjusting seat plate 11 is provided on the top plate 1 of the upper die seat, and a height-adjusting guide rail 12 arranged vertically is provided on the height-adjusting seat plate 11; the driving module 4 (reducer 42) is installed on the height-adjusting guide rail 12 through a slide; when working, the height position of the driving module 4 on the height-adjusting guide rail 12 is adjusted to adjust the working stroke of the screw rod, thereby realizing the adjustment of the downward pressure distance of the upper die seat lifting plate 2 to meet different types of processing requirements.

[0036] Furthermore, a rotating spring guide column 6 is provided between the upper die base rotating plate 3 and the upper die base lifting plate 2; a rotating countersunk through hole 22 is provided at the center position of the upper die base lifting plate 2, and the upper end of the rotating spring guide column 6 (the guide column head and the spring) is located in the rotating countersunk through hole 22 and is loosely matched with it; the lower end of the rotating spring guide column 6 passes through the rotating countersunk through hole 22 and is fixedly connected to the upper die base rotating plate 3; the rotating installation between the upper die base lifting plate 2 and the upper die base rotating plate 3 is realized, and at the same time, the upper die base rotating plate 3 can perform angle rotation adjustment with the rotating spring guide column 6 as the rotation center.

[0037] In order to limit the rotation angle of the upper die base rotating plate 3, two sets of adjustment limit mechanisms 8 are provided on one end surface of the upper die base lifting plate 2, which include: an adjustment nut seat 82 fixedly mounted on the upper die base lifting plate 2 and an adjustment screw 81 mounted on the adjustment nut seat 82; the end of the adjustment screw 81 abuts against the side end surface of the upper die base rotating plate 3;

[0038] When the angular position of the upper die base rotating plate 3 needs to be adjusted, the two adjustment limiter mechanisms 8 work in tandem. One set of adjustment screws 81 rotates forward, pushing it forward and applying thrust to the side end face of the upper die base rotating plate 3, causing it to rotate. Simultaneously, the other set of adjustment screws 81 rotates in the opposite direction, synchronously retracting along the internal threads of the adjustment nut seat 82, releasing pressure on the corresponding side. By continuously adjusting the extension and retraction of the two sets of adjustment screws 81, the offset angle and position of the upper die base rotating plate 3 can be precisely controlled, achieving high-precision limit and posture calibration during operation, improving the stability and reliability of the overall processing.

[0039] Furthermore, in order to improve the stability of the upper die base rotating plate 3 during the adjustment process, a plurality of rotary guide mechanisms 7 are provided on the upper end surface of the upper die base lifting plate 2, which include: a guide screw 73, a limiting cross bar 72 and a guide pulley 71;

[0040] A through guide slot 21 is also provided on the upper end surface of the upper die base lifting plate 2. The guide slot 21 is an arc-shaped structure as a whole.

[0041] The lower end of the guide screw 73 passes through the guide slot 21 and is fixedly connected to the upper die base rotating plate 3. When rotating, the guide screw 73 can move along the guide slot 21. The length of the guide slot 21 corresponds to the adjustable angle of the upper die base rotating plate 3. The guide slot 21 achieves a limiting effect on the maximum rotation stroke.

[0042] The limiting crossbar 72 is installed at the upper end of the guide screw 73 and is distributed perpendicularly thereto to prevent the guide screw 73 from falling out of the guide slot 21. Guide pulleys 71 are installed at both ends of the limiting crossbar 72, and the guide pulleys 71 are in contact with the upper end surface of the upper die base lifting plate 2.

[0043] The guide screw 73 is used to improve the connection stability between the upper mold base lifting plate 2 and the upper mold base rotating plate 3. During the adjustment process, the guide pulley 71 serves as the support point of the guide screw 73 and rolls along the upper end surface of the upper mold base lifting plate 2, converting the sliding friction into rolling friction, greatly reducing the resistance of the upper mold base rotating plate 3 during rotation, effectively reducing component wear and extending the service life of the equipment.
