Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to an adjustable-size label cutting device. Background Technology

[0002] In the label production and processing field, label cutting is a key step. Its cutting accuracy and efficiency directly affect label quality and production efficiency. Most of the current mainstream label cutting equipment is designed based on the principle of fixed die cutting or manual cutting. Among them, manual cutting devices are widely used in small and medium batch label processing scenarios due to their low cost and convenient operation.

[0003] Existing label cutting devices, due to their cutting structure where the cutter rotates and presses down around a single vertex of the base, can only cut one side of the label during the cutting process. If a rectangular cut of the label is required, the label position must be adjusted manually multiple times and the pressing operation repeated. This not only increases the number of operation steps, but also makes it easy for the label edge to become skewed due to human positioning errors.

[0004] Therefore, to address the shortcomings of existing label cutting devices during use, an adjustable label cutting device can be designed. By setting an adjustment frame assembly consisting of a crossbeam and a connecting rod above the cutting plate, and symmetrically arranging two sets of cutting blade assemblies between the crossbeams, the device can simultaneously perform bidirectional cutting in both the length and width directions of the label, reducing the number of manual positioning operations and thus facilitating the solution of the aforementioned problems. Utility Model Content

[0005] To overcome the shortcomings of existing label cutting devices, which can only cut one side of the label and require manual adjustment of the label position and repeated pressing operations to complete the rectangular cutting of the label, this utility model provides an adjustable size label cutting device.

[0006] The technical solution is as follows: An adjustable label cutting device includes a cutting plate, a movable connecting seat, an adjusting frame assembly, a cutting blade assembly, and a pressing handle; the upper part of the cutting plate is provided with an adjusting frame assembly for adjusting according to the label size, the adjusting frame assembly includes two sets of crossbeams, the two sets of crossbeams are symmetrically arranged above both ends of the cutting plate, and two sets of adjustable-space cutting blade assemblies are symmetrically arranged between the two sets of crossbeams, the rear center of the cutting plate is provided with a movable connecting seat for connecting the adjusting frame assembly, and the front end of the adjusting frame assembly is provided with a cutting plate for applying pressure.

[0007] Furthermore, two sets of connecting rods are installed between the two ends of the two sets of crossbeams, and the two sets of crossbeams are fixedly connected by the two sets of connecting rods. Multiple sets of adjustment grooves are evenly opened at the edges of the two sets of crossbeams.

[0008] Furthermore, each of the multiple adjustment slots is equipped with a locking bolt at its center, and two sets of connecting rods for connecting the lower pressure handle are symmetrically arranged at the front end of a set of crossbeams near the lower pressure handle.

[0009] Furthermore, the cutting blade assembly includes a fixing strip and a blade. Both ends of the fixing strip are provided with connectors extending into the adjustment groove. The center of the connector is provided with a sleeve hole corresponding to the locking bolt, and a locking nut corresponding to the locking bolt is provided above the sleeve hole.

[0010] Furthermore, the lower end of the fixing strip is provided with a clamping strip, the blade is located below the clamping strip, and the lower end of the clamping strip is provided with a clamping groove corresponding to the blade.

[0011] Furthermore, the surface of the movable connecting seat is provided with multiple sets of movable connecting grooves, and the center of the side wall of the movable connecting groove is provided with a movable connecting hole. A connecting block corresponding to the movable connecting groove is provided at the rear end of a set of crossbeams near the movable connecting seat, and the two ends of the connecting block are provided with movable shafts corresponding to the movable connecting holes.

[0012] Furthermore, the surface of the cutting board is provided with cutting grooves corresponding to the blades. Multiple sets of cutting grooves are provided, and the multiple sets of cutting grooves are arranged linearly from the center of the cutting board to both sides.

[0013] The beneficial effects are as follows: Compared to existing label cutting devices, which have shortcomings in use, this application, through the bidirectional cutting design of the adjustment frame assembly and two sets of cutting blade assemblies, only requires one positioning and one pressing to complete the cutting of the label length and width, eliminating the need for multiple label adjustments and significantly improving production efficiency in small and medium batch label processing scenarios; through multiple sets of linear adjustment slots on the crossbeam, the label length and width can be flexibly adjusted without changing any components, adapting to different label cutting requirements and greatly enhancing the versatility of the device; the hinged structure of the movable connecting seat ensures vertical cutting by the blades, and the two sets of cutting blade assemblies are subjected to force synchronously, effectively avoiding the problem of skewed cutting edges caused by positioning deviation or uneven force.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figures 1-4 As shown, an adjustable label cutting device includes a cutting plate 1, a movable connecting seat 2, an adjusting frame assembly 3, a cutting blade assembly 4, and a pressing handle 5. The upper part of the cutting plate 1 is provided with an adjusting frame assembly 3 for adjusting according to the label size. The adjusting frame assembly 3 includes two sets of crossbeams 301, which are symmetrically arranged above both ends of the cutting plate 1. Two sets of cutting blade assemblies 4 with adjustable spacing are symmetrically arranged between the two sets of crossbeams 301. The rear center of the cutting plate 1 is provided with a movable connecting seat 2 for connecting the adjusting frame assembly 3, and the front end of the adjusting frame assembly 3 is provided with a cutting plate 1 for applying pressure.

[0022] Two sets of connecting rods 302 are installed between the two ends of the two sets of crossbeams 301. The two sets of crossbeams 301 are fixedly connected by the two sets of connecting rods 302. Multiple sets of adjustment grooves 305 are evenly opened at the edges of the two sets of crossbeams 301. The symmetrically arranged crossbeams 301 are fixedly connected by the two sets of connecting rods 302 to form a stable rectangular frame structure, which prevents the crossbeams 301 from shifting or shaking due to force during the cutting process. The multiple sets of adjustment grooves 305 at the edges of the crossbeams 301 provide a multi-level, linear adjustment space for the cutting blade assembly 4. The distance between the two sets of cutting blade assemblies 4 can be flexibly adjusted according to the length and width requirements of different sized labels.

[0023] Each of the multiple adjustment slots 305 has a locking bolt 306 at its center. Two sets of connecting rods 302 are symmetrically arranged at the front end of a set of crossbeams 301 near the lower pressure handle 5. By using the locking bolts 306 at the center of the adjustment slots 305 in conjunction with the locking nuts of the subsequent cutting blade assembly 4, the cutting blade assembly 4 can be quickly locked after being adjusted to the target position, preventing the blade assembly from shifting due to pressure or vibration during the cutting process. The two sets of connecting rods 302 connect the lower pressure handle 5, which can evenly transmit the manual pressing force to the entire adjustment frame assembly 3, ensuring that the two sets of cutting blade assemblies 4 contact the label simultaneously and synchronously, reducing the label edge skewing caused by uneven force.

[0024] The cutting blade assembly 4 includes a fixing strip 401 and a blade 406. Both ends of the fixing strip 401 are provided with connectors 402 extending into the adjustment groove 305. The center of the connector 402 is provided with a sleeve hole 403 corresponding to the locking bolt 306. Above the sleeve hole 403 is a locking nut corresponding to the locking bolt 306. The connecting strip 402 at both ends of the fixing strip 401 is directly embedded into the adjustment groove 305, and the sleeve hole 403 cooperates with the locking bolt 306. The cutting blade assembly 4 can be installed without complicated tools.

[0025] The lower end of the fixing strip 401 is provided with a clamping strip 404, and the blade 406 is located below the clamping strip 404. The lower end of the clamping strip 404 is provided with a corresponding clamping groove 405 for the blade 406. The blade 406 is wrapped and fixed by the clamping groove 405 to prevent the blade 406 from moving or falling off due to force during cutting, thus ensuring operational safety.

[0026] Multiple sets of movable connecting grooves 7 are provided on the surface of the movable connecting seat 2. A movable connecting hole 8 is provided through the center of the side wall of the movable connecting groove 7. A connecting block 303 corresponding to the movable connecting groove 7 is provided at the rear end of a set of crossbeams 301 near the movable connecting seat 2. Movable shafts 304 corresponding to the movable connecting holes 8 are provided at both ends of the connecting block 303. The connecting block 303 is embedded in the movable connecting groove 7. The movable shaft 304 and the movable connecting hole 8 cooperate to form a hinge structure, so that the adjustment frame assembly 3 can be flexibly flipped and pressed down around the movable connecting seat 2 to ensure that the blade group acts vertically on the label surface during the cutting process and avoids uneven cutting edges caused by flipping and jamming.

[0027] The surface of the cutting plate 1 is provided with cutting grooves 6 corresponding to the blade 406. There are multiple sets of cutting grooves 6, which are arranged linearly from the center of the cutting plate 1 to both sides. The cutting grooves 6 correspond to the positions of the blade 406. When cutting, the blade 406 can be embedded in the cutting groove 6, which not only ensures that the label is completely cut off, but also prevents the blade edge of the blade 406 from directly contacting the cutting plate 1 and causing wear, thus extending the service life of the blade 406. The multiple sets of linearly arranged cutting grooves 6 correspond to the multiple sets of adjustment grooves 305 on the crossbeam 301. No matter what spacing the cutting blade assembly 4 is adjusted to, a matching cutting groove 6 can be found.

[0028] When working, the staff first selects the appropriate spacing of the adjustment groove 305 by tightening the nut according to the size of the label to be cut, and then inserts the connectors 402 at both ends of the fixing strip 401 into the selected adjustment groove 305 to adapt to the size of the label. After adjusting to the target position, the staff tightens the locking bolt 306 and the locking nut to fix the cutting blade assembly 4 on the crossbeam 301.

[0029] Then place the label to be cut flat on the cutting board 1, ensuring that the label is roughly centered. Hold the pressing handle 5 and press down evenly, so that the adjusting frame assembly 3 rotates and presses down around the movable connecting seat 2. The blade 406 of the cutting knife assembly 4 is embedded in the cutting groove 6 on the surface of the cutting board 1, completing the rectangular cutting of the label.

[0030] Its working principle is as follows: the adjustment frame assembly 3 consists of two sets of crossbeams 301 and two sets of connecting rods 302 forming a stable rectangular frame. The multiple sets of linear adjustment grooves 305 on the surface of the crossbeams 301 provide multiple adjustment spaces for the cutting blade assembly 4. When the locking bolts 306 and nuts are loosened, the connector 402 of the cutting blade assembly 4 can slide along the adjustment grooves 305. By utilizing the linear distribution characteristics of the adjustment grooves 305, the spacing of the cutting blade assembly 4 can be continuously adjusted to adapt to the label requirements of different lengths and widths.

[0031] Two sets of cutting blade assemblies 4 are symmetrically arranged between the crossbeams 301. When the pressing handle 5 applies pressure to the adjusting frame assembly 3, the two sets of cutting blade assemblies 4 move downwards simultaneously, which can simultaneously achieve bidirectional cutting in both the length and width directions of the label. Unlike existing devices, there is no need to manually adjust the label position multiple times and repeat the pressing operation. The surface of the cutting plate 1 is provided with cutting grooves 6 corresponding to the blades 406. The cutting grooves 6 are arranged linearly from the center of the cutting plate 1 to both sides. When pressing down to cut, the blades 406 can be embedded in the cutting grooves 6, which not only ensures that the label is completely cut off, but also prevents the blade edge of the blade 406 from directly contacting the cutting plate 1 and causing wear, thus extending the service life of the blades 406.

[0032] Its beneficial effects are significant. This application uses the bidirectional cutting design of the adjustment frame component 3 and two sets of cutting blade components 4 to complete the cutting of the label length and width directions with only one positioning and one pressing, eliminating the need for multiple label adjustment steps and greatly improving the production efficiency of small and medium batch label processing scenarios. Through the multiple sets of linear adjustment grooves 305 on the crossbeam 301, the label length and width can be flexibly adjusted without replacing any components, which can adapt to the cutting needs of different specifications of labels and greatly enhance the versatility of the device. The hinge structure of the movable connecting seat 2 ensures that the blade 406 cuts vertically and the two sets of cutting blade components 4 are subjected to force synchronously, effectively avoiding the problem of skewed cutting edges caused by positioning deviation or uneven force.
