Description

Technical Field

[0001] This utility model relates to the field of cutting machines, and more specifically, to a longitudinal cutting machine. Background Technology

[0002] Currently, most printers print on roll media, so most printing equipment only needs a horizontal cutter to meet the requirements. However, some printed materials, such as labels, cannot be solved simply by horizontal cutting and require vertical cutting. Therefore, printers have introduced rotary cutters, commonly used in engraving machines, to meet both horizontal and vertical cutting requirements. Horizontal and rotary cutters each have their advantages and disadvantages. While horizontal cutters can only perform horizontal cutting, their structure is relatively simple and their cost is lower. Therefore, most users tend to use horizontal cutters when printing products that only require horizontal cutting. Rotary cutters, while more versatile, are relatively more expensive. Different production batches or varying customer needs necessitate changing the cutters on existing printing equipment according to the specific product being printed, a process that is cumbersome and inconvenient.

[0003] Utility model patent CN222022267U discloses a longitudinal cutting mechanism and paper cutter, including at least one set of longitudinal blade assemblies. The longitudinal blade assembly includes a blade holder, a rocker arm hinged to the blade holder, and the free end of the rocker arm connected to the blade holder via a first driving member, which causes the rocker arm to swing longitudinally. The rocker arm has at least one rotatable first support member, and the rocker arm is also hinged to a movable arm via a connecting arm. The movable arm has a rotatable second support member, and an elastic support member is provided between the movable arm and the connecting arm. The second support member and the first support member jointly support a creasing blade ring located on their outer sides. This longitudinal cutting mechanism and paper cutter avoids the need to remove the second support member or other components when assembling and disassembling the creasing blade ring, making disassembly and assembly more convenient and quick. Furthermore, the longitudinal assembly enables creasing and cutting operations on the paper material. However, the longitudinal cutting mechanism and the creasing blade ring in the paper cutter have no vertical power mechanism, resulting in low cutting efficiency. Furthermore, the blade holder does not have the function of left-right and up-down movement adjustment, which is inconvenient for fabric loading and for adjusting the spacing between the blades. Utility Model Content

[0004] In order to achieve powered cutting of the rotating blades, adjust the spacing between several rotating blades to adapt to cutting operations of different widths, and facilitate fabric loading, the technical solution adopted by this utility model is: a longitudinal cutting machine, including a support base assembly, a crossbeam, rotating blades, a blade drive mechanism, and several movable blade holders.

[0005] The crossbeam is liftably mounted on the support base assembly to support several of the movable tool holders;

[0006] Several of the aforementioned movable tool holders are movably mounted on the crossbeam via a linear drive mechanism, for mounting and driving the rotating blades to move;

[0007] The rotating blade is mounted on the movable blade holder and is used to cut the printing medium longitudinally;

[0008] The blade drive mechanism is installed on the underside of the crossbeam and is used to drive the rotating blade to rotate and cut.

[0009] Based on the above, in order to facilitate installation and driving, the lower end of the movable tool holder is provided with a blade mounting seat for mounting the rotating blade, and the rotating blade is connected to the blade driving mechanism through a transmission mechanism.

[0010] Based on the above, the blade driving mechanism includes a cutting drive motor and a rotating optical shaft that is driven by the cutting drive motor. The transmission mechanism is connected to the rotating optical shaft through a one-way needle roller bearing.

[0011] Based on the above, the support base assembly includes a fixed support base and a movable support base. The movable support base is laterally slidably disposed on the fixed support base, and the crossbeam is vertically and vertically connected to the movable support base.

[0012] Based on the above, in order to facilitate movement, the fixed support is provided with a translation motor and a first guide rail. The translation motor slides on the first guide rail through the movable support via a ball nut and a ball screw.

[0013] Based on the above, in order to facilitate lifting and lowering, the movable support is provided with a second guide rail and a lifting cylinder, and the lifting cylinder pushes the crossbeam to rise and fall along the second guide rail.

[0014] Based on the above, in order to facilitate linear movement, the linear drive mechanism includes a third guide rail and a rack respectively disposed on the back side of the crossbeam, a moving motor disposed on the upper part of the moving tool holder, and a gear disposed on the moving motor that meshes with the rack for transmission.

[0015] Based on the above, the movable tool holder is an inverted L-shaped tool holder, and a cable chain connecting the inverted L-shaped tool holder is also provided on the top of the crossbeam.

[0016] Based on the above, a sensing plate is provided on one side of the movable support base, and a position sensor for sensing the position of the sensing plate is provided on one side of the fixed support base.

[0017] This utility model has substantial features and advancements compared to existing technologies. Specifically, the longitudinal cutting machine provided by this utility model connects a crossbeam equipped with rotating blades to a pair of fixed support seats in a manner that allows for horizontal and vertical movement. This allows the rotating blades to be raised during fabric loading, facilitating fabric loading and adjusting the position and level of the crossbeam. Furthermore, by movably mounting several rotating blades on a rotating optical shaft via blade mounting seats and one-way needle roller bearings, and using an optical shaft drive motor to drive the rotating optical shaft to rotate, the rotating blades are driven to rotate, thus achieving powered cutting and improving cutting efficiency.

[0018] Furthermore, by connecting the blade mounting base to the movable blade holder, and movably mounting the movable blade holder on the crossbeam via a linear drive mechanism, the spacing between several rotating blades can be adjusted to accommodate cutting operations of different widths.
