Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of carton forming, and relates to a cutting device, in particular to a cutting device capable of cutting on two sides. BACKGROUND
[0002] When the existing products are transported and sold, more cartons or paper boxes are needed for packaging. In order to facilitate subsequent packaging use and make the folding area of the carton or paper box neat, an indentation needs to be pressed in the folding area of the paperboard. After the indentation of the paperboard is completed, the paperboard needs to be cut to remove the excess waste paper and retain the paperboard required for carton forming.
[0003] In the prior art, in order to improve the cutting efficiency, two ways can be used to improve the cutting efficiency. Way one is to install two cutting heads on a beam, and the moving direction of the beam is the same as the conveying direction of the paperboard, and the two cutting heads cut the two sides of the paperboard synchronously to improve the cutting efficiency. Way two is to set two beams, and the moving direction of the two beams is the same as the conveying direction of the paperboard, and one cutting head is arranged on each beam, and the two cutting heads cut the two sides of the paperboard respectively, wherein one cutting head can cut from the feeding end of the paperboard to the discharging end of the paperboard, and the other cutting head can cut from the discharging end of the paperboard to the feeding end of the paperboard to improve the cutting efficiency.
[0004] However, the above two cutting methods have a disadvantage. If the structure of way one is adopted, the cutting edge lines on the two sides of the paperboard need to be symmetrically arranged. If the shapes of the edge lines on the two sides are different, the structure of way one cannot be used for cutting. If the structure of way two is adopted, although it can meet the cutting of the edge lines on the two sides with different shapes, when the two beams move towards each other, the cutting heads on the corresponding beams cannot cut again after crossing the other beam, and the cutting of the two sides of the paperboard can be completed only after the two beams retreat alternately once, which leads to a complex cutting process. SUMMARY
[0005] The present application aims to solve the above problems of the prior art, and provides a cutting device capable of improving the cutting efficiency, increasing the amount of finished products per unit time, and simplifying the cutting process.
[0006] The purpose of the present application can be achieved by the following technical scheme: a cutting device capable of cutting on two sides, comprising:

[0016] A first motor support serving as a mounting structure of the translation motor;
[0017] A crossbeam support, one end of which is connected to the first motor support, and the other end of which is connected to the crossbeam, wherein the crossbeam support causes a height difference between the crossbeam and the position of the first transmission part on the gantry.
[0018] In the above cutting device capable of cutting from both sides, a bump stop is arranged on the first motor support, and a buffer pad is arranged on one end of the bump stop, wherein the two bump stops of the two driving mechanisms on the same gantry are oppositely arranged, and the axes of the two bump stops are collinear.
[0019] The sum of the lengths of the two anti-collision columns is greater than the minimum relative distance between the two beams.
[0020] In the above-mentioned cutting device capable of cutting on both sides, the cutting head comprises a moving assembly and a cutter seat assembly connected thereto, and the cutter seat assembly is moved along the length direction of the beam through the moving assembly, wherein the cutter seat assembly serves as the mounting structure of the cutting knife.

[0036] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.
[0037] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications will also change accordingly.
[0038] As shown in FIG. 1, the present application provides a cutting device capable of cutting on both sides, which comprises: Figs. 1-3
[0039] a rack 100, a paperboard cutting channel is arranged on the rack 100, and the two ends of the paperboard cutting channel are a paperboard feeding end and a paperboard discharging end, respectively;
[0040] a paper feeding module, comprising a conveyor belt 200 rotating circumferentially in the paperboard cutting channel, which transports the paperboard from the paperboard feeding end to the paperboard discharging end;
[0041] two gantries 300, each of which spans the paperboard cutting channel, and the two ends of each gantry 300 are connected to the corresponding side of the rack 100, wherein each gantry 300 movably connects two driving mechanisms 400 that can move along the length direction of the gantry 300;
[0042] Two crossbeams 500 are provided, with one end of each crossbeam 500 connected to one of the two drive mechanisms 400 on one of the two gantry frames 300, and the other end of each crossbeam 500 connected to one of the two drive mechanisms 400 on the other gantry frame 300. The two crossbeams 500 are parallel to each other, and each crossbeam 500 is provided with a cutting head 600 that can move along the length of the corresponding crossbeam 500. The movement trajectories of the corresponding cutting heads 600 on the two crossbeams 500 can form parallel misalignment.
[0043] It is worth mentioning that the creased cardboard is generally like... Fig. 1 As shown, it has multiple transverse and vertical indentations. The transverse indentations are perpendicular to the paperboard's conveying direction, while the vertical indentations are parallel to it. The vertical indentations form the edge lines of the paperboard, i.e., the cutting lines, and the shapes of the cutting lines on both sides of the paperboard are different. The two methods for improving processing efficiency used in the background technology cannot achieve the same result. Fig. 1 The cardboard shown is cut.
[0044] In this embodiment, the two cutting heads 600 on the two crossbeams 500 are equivalent to two cars on a two-way road. One cutting head 600 can move from the paperboard feed end to the paperboard discharge end for cutting, and the other cutting head 600 can move from the paperboard discharge end to the paperboard feed end for cutting. Since the two crossbeams 500 are parallel to each other and the length direction of the crossbeams 500 is consistent with the conveying direction of the paperboard, the two cutting heads 600 can achieve cross-staggered cutting without interfering with each other.
