Description

Technical Field

[0001] This utility model belongs to the technical field of label cutting equipment, and relates to a pressing upper mold base used in label cutting equipment. Background Technology

[0002] In the field of label cutting machines, traditional equipment generally adopts a single-point drive mode for the upper die base structure. This type of design typically installs a single drive unit at the center of the top plate of the upper die base, and transmits the driving force to the upper die base lifting plate through a linkage or transmission mechanism, thereby driving the cutter to perform a vertical cutting action.

[0003] However, in the cutting process, this single-point drive method can easily cause uneven force on the upper mold base lifting plate because the driving force is concentrated in the center, which can lead to overall mold deformation, cause the cutting trajectory of the tool to deviate, and result in quality problems such as burrs and dimensional errors on the label edge, which seriously affects the product qualification rate. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

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

[0006] The upper mold base lifting plate is located at the lower end of the upper mold base top plate, and the upper mold base rotating plate is rotatably installed at the lower end of the upper mold base lifting plate;

[0007] The top plate of the upper mold base is equipped with four sets of drive modules for vertically raising and lowering the upper mold base lifting plate. Each set of drive modules is arranged in a rectangular array at the upper end of the upper mold base lifting plate. The drive structure of each set of drive modules is connected to each corner of the upper mold base lifting plate.

[0008] As a further embodiment of this utility model: the drive module is located at the four corners of the top plate of the upper mold base, and includes: a drive 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 mold base top plate. The lead screw sleeve is installed in the upper mold base top plate. The upper end of the transmission lead screw is connected to the reducer for transmission, and the lower end passes through the lead screw sleeve and abuts against the corner of the upper mold base lifting plate.

[0010] Furthermore, a plurality of lifting spring guide posts are provided between the top plate of the upper mold base and the lifting plate of the upper mold base. The top plate of the upper mold base is provided with a corresponding number of lifting countersunk through holes. The upper end of the lifting spring guide post and the spring are located in the lifting countersunk through holes and are clearance-fitted with them. The lower end of the lifting spring guide post passes through the lifting countersunk through holes and is fixedly connected to the lifting plate of the upper mold base.

[0011] As a further embodiment of this utility model: a height adjustment plate is also provided on the top plate of the upper mold base, and a height adjustment guide rail is provided on the height adjustment plate in a vertical direction; the drive module is mounted on the height adjustment guide rail via a slide.

[0012] As a further embodiment of this utility model: a rotating spring guide post is provided between the upper mold base rotating plate and the upper mold base lifting plate; a rotating countersunk through hole is provided at the center of the upper mold base lifting plate, the upper end of the rotating spring guide post is located in the rotating countersunk through hole and is clearance-fitted with it; the lower end of the rotating spring guide post passes through the rotating countersunk through hole and is fixedly connected to the upper mold base rotating plate.

[0013] As a further embodiment of this utility model: two sets of adjustment and limiting mechanisms are provided on one side end face of the upper mold base lifting plate, including: 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 abuts against the side end face of the upper mold base rotating plate.

[0014] As a further embodiment of this utility model: the upper end face of the upper mold base lifting plate is also provided with a complex array of rotary guide mechanisms, which include: guide screws, limit crossbars and guide pulleys;

[0015] The upper end surface of the upper mold base lifting plate is also provided with a through guide groove, which has an overall arc-shaped structure.

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

[0017] The limiting crossbar is installed at the upper end of the guide screw and is distributed perpendicular to it; both ends of the limiting crossbar are equipped with guide pulleys.

[0018] The beneficial effects of this invention are as follows: By arranging four sets of drive modules in a rectangular array, a surface-driven downward pressing effect is achieved. Compared to the traditional single-point drive method, this structure uses a four-servo system to adjust the pressure, enabling intelligent operation and reducing the technical requirements for operators in existing equipment; it greatly simplifies the difficulty of die-cutting operations. Independent pressure adjustment is available at each of the four corners and on all four sides; overall pressure increase and decrease can be achieved with a single button. It boasts a high degree of intelligence, solving the problem of older equipment being unable to adjust the pressure at a single point on the mold.

[0019] It effectively avoids mold distortion caused by uneven force, ensures the accuracy of the vertical cutting trajectory of the cutter, and the multi-drive point collaborative operation disperses the load of a single component, reduces the wear rate of the drive module and transmission structure, and reduces maintenance frequency and cost; in addition, the stable surface drive mode ensures that the force on the cutter is constant during the cutting process, and can maintain efficient and stable cutting quality even when facing high load conditions such as multi-layer label stacking, which greatly improves the production efficiency and reliability of the label flat cutter and provides a strong guarantee for high-precision, large-volume label cutting operations.

Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] This utility model provides a reference. Figures 1-5 In this embodiment of the present invention, a pressing upper mold base applied in a label cutting equipment includes: an upper mold base top plate 1, an upper mold base lifting plate 2, and an upper mold base rotating plate 3.

[0030] The upper mold base lifting plate 2 is located at the lower end of the upper mold base top plate 1, and the upper mold base rotating plate 3 is rotatably installed at the lower end of the upper mold base lifting plate 2 for the installation of cutting tools. During operation, the angle of the cutting tools can be adjusted by rotating the upper mold base rotating plate 3 to meet different usage requirements.

[0031] Four drive modules 4 are installed on the top plate 1 of the upper mold base to drive the upper mold base lifting plate 2 to move vertically. Each drive module 4 is arranged in a rectangular array at the upper end of the upper mold base lifting plate 2. The drive structure of each drive module 4 is connected to each corner of the upper mold base lifting plate 2. During operation, the four drive modules 4 operate synchronously, driving the upper mold base lifting plate 2 to descend smoothly through the force points at the corners. Compared with the traditional single-point drive, this structural design can achieve the working effect of surface drive pressing through the uniform pressing effect of the four corners, ensuring that the cutter 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 drive module 4 is located at the four corners of the upper mold base top plate 1, and includes: drive motor 41, reducer 42, transmission screw 43 and screw sleeve 44;

[0033] The drive motor 41 and the reducer 42 are both mounted on the upper surface of the upper mold base top plate 1. The lead screw sleeve 44 is installed in the upper mold base top plate 1. The upper end of the transmission lead screw 43 is engaged with the reducer 42, and the lower end passes through the lead screw sleeve 44 and abuts against the corner of the upper mold base lifting plate 2 (as the drive structure of the drive module 4). During operation, the drive motors 41 of each drive module 4 work synchronously, and the reducer 42 converts the rotational power output of the drive motor 41 into the linear motion of the transmission lead screw 43, thereby driving the upper mold base lifting plate 2 to move downward.

[0034] Furthermore, a plurality of lifting spring guide posts 5 are provided between the upper mold base top plate 1 and the upper mold base lifting plate 2. The upper mold base top plate 1 is provided with a corresponding number of lifting countersunk through holes 13. The upper end of the lifting spring guide post 5 and the spring are located in the lifting countersunk through holes 13 and are fitted with them with clearance. The lower end of the lifting spring guide post 5 passes through the lifting countersunk through holes 13 and is fixedly connected to the upper mold base lifting plate 2. This realizes the connection between the upper mold base lifting plate 2 and the upper mold base top plate 1, while ensuring the vertical freedom of the upper mold base lifting plate 2. During the descent of the upper mold base lifting plate 2, the spring assembly in the lifting spring guide post 5 will be compressed by force. When the transmission screw 43 is reset upward, the spring assembly of the lifting spring guide post 5 rebounds, causing the upper mold base lifting plate 2 to move upward and reset, thereby completing one lifting cycle of the upper mold base lifting plate 2. This cycle is repeated to work in conjunction with the lower mold base structure to realize the label cutting work.

[0035] Furthermore, an adjustable height plate 11 is provided on the top plate 1 of the upper mold base, and an adjustable height guide rail 12 is provided on the adjustable height plate 11. The drive module 4 (reducer 42) is mounted on the adjustable height guide rail 12 via a slide. During operation, by adjusting the height position of the drive module 4 on the adjustable height guide rail 12, the working stroke of the lead screw is adjusted, thereby adjusting the downward pressing distance of the upper mold base lifting plate 2 to meet different types of processing requirements.

[0036] Furthermore, a rotating spring guide post 6 is provided between the upper mold base rotating plate 3 and the upper mold base lifting plate 2; a rotating countersunk through hole 22 is provided at the center of the upper mold base lifting plate 2, and the upper end (guide post head and spring) of the rotating spring guide post 6 is located in the rotating countersunk through hole 22 and is clearance-fitted with it; the lower end of the rotating spring guide post 6 passes through the rotating countersunk through hole 22 and is fixedly connected to the upper mold base rotating plate 3; thus realizing the rotational installation between the upper mold base lifting plate 2 and the upper mold base rotating plate 3, and enabling the upper mold base rotating plate 3 to perform angle rotation adjustment with the rotating spring guide post 6 as the rotation center.

[0037] In order to limit the rotation angle of the upper mold base rotating plate 3, two sets of adjustment and limiting mechanisms 8 are provided on one side end face of the upper mold base lifting plate 2, including: an adjusting nut seat 82 fixedly installed on the upper mold base lifting plate 2 and an adjusting screw 81 installed on the adjusting nut seat 82; the end of the adjusting screw 81 abuts against the side end face of the upper mold base rotating plate 3.

[0038] When the angle position of the upper mold base rotating plate 3 needs to be adjusted, the two sets of adjustment and limiting mechanisms 8 work together. One set of adjusting screws 81 is rotated, pushing it forward and applying a thrust to the side end face of the upper mold base rotating plate 3 to achieve rotation. Simultaneously, the other set of adjusting screws 81 retracts synchronously along the internal thread of the adjusting nut seat 82 by rotating in the opposite direction, releasing the pressure on the corresponding side. By continuously adjusting the extension and retraction of the two sets of adjusting screws 81, the offset angle and position of the upper mold base rotating plate 3 can be precisely controlled, achieving high-precision limiting and attitude calibration during operation, thus improving the overall stability and reliability of the machining process.

[0039] Furthermore, in order to improve the stability of the upper mold base rotating plate 3 during the adjustment process, the upper end face of the upper mold base lifting plate 2 is also provided with a complex array of rotating guide mechanisms 7, which includes: guide screws 73, limit crossbars 72 and guide pulleys 71.

[0040] The upper end surface of the upper mold base lifting plate 2 is also provided with a through guide groove 21, which has an overall arc-shaped structure.

[0041] The lower end of the guide screw 73 passes through the guide groove 21 and is fixedly connected to the upper mold base rotating plate 3. When rotating, the guide screw 73 can move along the guide groove 21, and the length of the guide groove 21 corresponds to the adjustable angle of the upper mold base rotating plate 3. The maximum rotation stroke is limited by the guide groove 21.

[0042] The limiting crossbar 72 is installed on the upper end of the guide screw 73 and is distributed perpendicular to it to prevent the guide screw 73 from coming out of the guide groove 21; both ends of the limiting crossbar 72 are equipped with guide pulleys 71, which are in contact with the upper end surface of the upper mold base lifting plate 2.

[0043] The guide screw 73 improves 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 sliding friction into rolling friction. This significantly reduces the resistance when the upper mold base rotating plate 3 rotates, effectively reducing component wear and extending the service life of the equipment.

[0044] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
