Abstract
Description
Technical Field
[0001] This utility model relates to the field of label production technology, specifically to a label die-cutting tool assembly. Background Technology
[0002] Label die-cutting is a common technology in the printing and packaging industry. Products such as self-adhesive labels, packaging boxes, and trademarks all require die-cutting. The die-cutting tool assembly is the core component of the die-cutting equipment. Traditional label die-cutting tool assemblies typically consist of a blade, a blade holder, and a fixing device. Mechanical pressure forces the blade into the material to complete the cut. However, traditional die-cutting blades are usually fixed in design, making quick replacement or adjustment difficult. This results in low efficiency when producing labels of different shapes and sizes. Furthermore, the blades are subjected to significant instantaneous pressure during slitting, especially the blade head, which is prone to fatigue damage under frequent, instantaneous stress. Utility Model Content
[0003] The purpose of this utility model is to provide a reasonably designed label die-cutting tool assembly that addresses the defects and shortcomings of the existing technology and can solve the aforementioned defects.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: It includes a housing, on which several connectors for installation are connected, and side covers are respectively provided at both ends of the housing. A cutter is provided in the housing, and a groove with the same width as the cutter is opened at the bottom of the housing. Side limiting plates are provided inward on both sides of the groove. The cutter is movably disposed in the channel formed between the two side limiting plates. A horizontal plate is provided above the cutter, and a lower pressure plate is connected to the lower left and right sides of the horizontal plate through multiple connecting posts. A lower support plate is provided inside the housing on the outside of the side limiting plates. Several buffer springs are provided below the lower support plates. The lower pressure plate is located above the lower support plates. A clamping plate is installed on the top side of the housing through multiple guide post and guide sleeve assemblies. Multiple sets of adjustment structures are provided above the clamping plate.
[0005] Preferably, the adjustment structure includes a fixed block mounted on the pressure plate, a movable plate slidably mounted on the fixed block in a vertical direction via multiple sliding rods, an upper spring between the movable plate and the fixed block, a drive motor on the top surface of the housing, the shaft of the drive motor movably passing through the top wall of the housing and connected to a threaded rod, a threaded hole on the movable plate, and the threaded rod being threadedly connected to the threaded hole.
[0006] Preferably, the horizontal plate is provided with multiple limiting protrusions below each fixing block, and the bottom of the pressing plate has a groove that matches the limiting protrusions, with the limiting protrusions being engaged in the groove.
[0007] Preferably, multiple guide strips are vertically arranged on both inner side walls of the housing, and the lower support plate has a groove matching the guide strips on its side, with the guide strips disposed in the groove.
[0008] Preferably, each sliding rod has a limiting block at its top end.
[0009] The beneficial effects of this utility model after adopting the above structure are:
[0010] 1. This utility model uses a bidirectional spring design to allow the cutter to be pressed in both directions simultaneously. This provides elastic buffering during slitting, preventing damage caused by excessive cutting force or collision caused by excessive rebound, and preventing fatigue damage to the cutter head.
[0011] 2. By adjusting the components, this utility model can not only adjust the downward pressure of the cutter to adapt to different materials, but also lift the pressure plate upwards, making it easy to replace the cutter. It is convenient and quick to use. 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] See Figures 1-3As shown, it includes a housing 1, with several connectors 3 for installation connected to the housing 1. Side covers 2 are provided at both ends of the housing 1. A cutter 5 is provided inside the housing 1. A groove with the same width as the cutter 5 is opened at the bottom of the housing 1. Side limiting plates 4 are provided inward on both sides of the groove. The cutter 5 is movably disposed in the channel formed between the two side limiting plates 4. A horizontal plate 6 is provided above the cutter 5. A lower pressure plate 8 is connected to the lower left and right sides of the horizontal plate 6 through multiple connecting posts 7. A lower support plate 9 is provided inside the housing 1 outside the side limiting plates 4. Several buffer springs 10 are provided below the lower support plate 9. The lower pressure plate 8 is located above the lower support plate 9. A pressure plate 12 is installed on the top side of the housing 1 through multiple guide post and guide sleeve assemblies 13. Multiple sets of adjustment structures are provided above the pressure plate 12.
[0019] The adjustment structure includes a fixed block 15 mounted on the pressure plate 12. A movable plate 17 is slidably mounted on the fixed block 15 in the vertical direction via multiple sliding rods 16. An upper spring 18 is provided between the movable plate 17 and the fixed block 15. A drive motor 20 is provided on the top surface of the housing 1. The rotating shaft of the drive motor 20 passes through the top wall of the housing 1 and is connected to a threaded rod 19. A threaded hole is provided on the movable plate 17, and the threaded rod 19 is threadedly connected to the threaded hole.
[0020] Multiple limiting protrusions 14 are provided on the horizontal plate 6 below each fixed block 15. The bottom of the pressing plate 12 has a groove that matches the limiting protrusions 14, and the limiting protrusions 14 are engaged in the groove.
[0021] Multiple guide bars 11 are vertically arranged on the inner two side walls of the housing 1, and the lower support plate 9 has a groove on its side that matches the guide bars 11, with the guide bars 11 located in the groove;
[0022] Limiting blocks are provided at the top of each sliding rod 16.
[0023] The principle and usage process of this utility model:
[0024] The housing 1 of this tool assembly is installed via the connector 3. When the cutter 5 needs to be installed, multiple drive motors 20 are started to rotate simultaneously. The rotation of the threaded rod 19 drives the movable plate 17 to rise, thereby gradually relaxing the upper spring 18 until the fixed block 15 rises, thus freeing up a position for the cutter 5. Then, the cutter 5 is inserted into the installation position. After aligning the position, the drive motor 20 is started in reverse, driving the movable plate 17 to press down, so that the clamping plate 12 presses the cutter 5. The limiting protrusion 14 is inserted into the groove of the clamping plate 12 to prevent the cutter 5 from shifting. At the same time, the two sides of the upper horizontal plate 6 of the cutter 5 are pressed down through the connecting column 7 and the lower pressure plate 8, pushing the lower support plate 9 to compress the buffer spring 10. Thus, the buffer spring 10 and the upper spring 18 achieve bidirectional elastic force control of the cutter 5.
[0025] During the cutting process, the cutter 5 will push the upper spring 18 upward after being subjected to force, compressing it. When the cutter 5 finishes cutting, the upper spring 18 pushes the cutter 5 downward. At this time, the buffer spring 10 will buffer it to prevent the fast cutter 5 from popping out quickly and causing a collision. The stroke of the drive motor 20 can also be adjusted to adjust the downward pressing height of the movable plate 17, thereby adjusting the spring's clamping force to meet the cutting requirements.
[0026] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
