[0041] Combine the following Figures 1 to 6 The embodiments of the present utility model are described.

[0042] This embodiment relates to a longitudinal cutting centering mechanism, which is used to adjust the positions among the machine table 2, the longitudinal cutting knife and the paperboard a, so as to finally realize the centering of the paperboard a and the machine table 2.

[0043] The longitudinal cutting centering mechanism includes: a base 1, a transverse movement component, a machine 2, a positioning component, an edge finding component and a controller (not shown in the figure). The machine 2 is driven by the transverse movement component to slide left and right along the base 1; the positioning component is arranged on the machine 2, and the edge finding component includes a first sensor 46 and a second sensor 47. The number of the edge finding components is two groups, and the two groups of the edge finding components are arranged left and right, and the two groups of the edge finding components are driven by the positioning component to slide left and right on the machine 2; the controller is connected to the first sensor 46, the second sensor 47, the positioning component, and the transverse movement component by signals.

[0044] After the longitudinal cutting width of the cardboard a is determined, the cardboard a enters the longitudinal cutting centering mechanism after the longitudinal cutting width becomes the set width. The controller moves the two edge finding components to the predetermined width through the position adjustment component, and then the transverse movement component moves the machine 2 to adjust the relative position of the cardboard a and the machine 2 until the first sensor 46 and the second sensor 47 of the two sets of edge finding components are in an open and closed state, which indicates that the edge of the cardboard a falls between the first sensor 46 and the second sensor 47 on both sides, and the cardboard a and the machine 2 are completely aligned; the longitudinal cutting centering mechanism realizes the alignment of the cardboard a and the machine 2 in a mechanized control manner, has the advantage of simple centering, and greatly improves the efficiency of changing the specifications of the cardboard a. The longitudinal cutting centering mechanism of this embodiment is particularly suitable for production lines for high-speed production of cardboard a.

[0045] Specifically, in this embodiment, two groups of edge-finding components are arranged symmetrically on the left and right sides. The two first sensors 46 are adjacent to each other and close to the inner side of the positioning component, while the two groups of second sensors 47 are arranged on the outside. When the first sensor 46 and the second sensor 47 of the edge-finding component on the left side are both in the on state, it indicates that the signals of the first sensor 46 and the second sensor 47 are both reflected by the cardboard a, and the left end of the cardboard a extends to the left of the second sensor 47. At this time, the controller needs to be used to drive the lateral movement component to drive the machine 2 to slide to the right as a whole until the first sensors 46 on both sides are in the on state and the second sensors 47 on both sides are in the off state, indicating that the two sides of the cardboard a just fall between the first sensors 46 and the second sensors 47 on both sides.

[0046] The positioning assembly includes a synchronous belt 41, a driving motor 42, a driving wheel 43 and a driven wheel 44, wherein the driving motor 42 is arranged on the machine table 2, and the driven wheel 44 is rotatably arranged on the machine table 2, the driving motor 42 is drivingly connected to the driving wheel 43, and the synchronous belt 41 is simultaneously transmission-connected to the driving wheel 43 and the driven wheel 44, the positioning assembly also includes a transverse tool group slide rail 48 arranged transversely on the machine table 2 and a tool group slide seat 49 sliding along the transverse tool group slide rail 48, a clamping plate 45 is provided on the tool group slide seat 49, and the clamping plate 45 clamps the synchronous belt 41, and the first sensor 46 and the second sensor 47 are both arranged on the tool group slide seat 49; the two groups of clamping plates 45 of the positioning assembly respectively clamp the two straight sections of the synchronous belt 41 moving in opposite directions. The positioning assembly adopts the structure of the synchronous belt 41 to drive the two sets of edge-finding assemblies to move separately. The two sets of edge-finding assemblies are respectively fixed on the two straight sections of the synchronous belt 41, so that when the synchronous belt 41 moves, the two sets of edge-finding assemblies move in opposite directions at the same time. During the movement, the moving center of the two cutters remains unchanged, so when the edge-finding assembly is adjusted, it is easier to keep consistent with the center position of the cardboard a.

[0047] The clamping plate 45 includes an upper pressing plate 451, a lower pressing plate 452 and a pressing plate bolt 453. The upper pressing plate 451 is fixedly connected to the knife group slide 49. The pressing plate bolt 453 is connected to the upper pressing plate 451 and the lower pressing plate 452, so that the upper pressing plate 451 and the lower pressing plate 452 clamp and fix the synchronous belt 41. The clamping plate 45 structure is used to clamp and fix the synchronous belt 41 through the upper pressing plate 451 and the lower pressing plate 452, so that the cutter assembly and the synchronous belt 41 can be conveniently synchronized. Since in this embodiment, the two cutter assemblies are synchronized with two different straight sections of the synchronous belt 41, it can be understood that the setting positions of the two cutter assemblies located on both sides need to be adjusted according to the actual positions.

[0048] One group of the clamps 45 closes the synchronous belt 41 at both ends of the synchronous belt 41. In addition to clamping the synchronous belt 41 through the cutter assembly to achieve the movement of the cutter assembly, the clamps 45 also clamp both ends of the synchronous belt 41 to close the synchronous belt 41. The clamp 45 structure realizes two functions at the same time, and the overall structure is more streamlined. Specifically, the synchronous belt 41 is a toothed synchronous belt 41. The toothed synchronous belt 41 has the advantages of not easy to slip, high transmission accuracy, and high transmission efficiency. Specifically, refer to Figure 4The group of clamps 45 that close the synchronous belt 41 also includes a profiling plate 5, the shape of which matches the shape of the synchronous belt 41. In this embodiment, the shape of the profiling plate 5 is also a toothed plate. The profiling plate 5 is located between the upper pressing plate 451 and the lower pressing plate 452, and is pressed on the synchronous belt 41 by the upper pressing plate 451 and the lower pressing plate 452 to close the synchronous belt 41. The synchronous belt 41 is less likely to loosen when the profiling plate 5 is used for closing.

[0049] The transverse movement assembly includes a transverse movement rail, a transverse movement roller 31, and a linear drive 32. The transverse movement rail is arranged on the base 1. The number of the transverse movement rollers 31 is more than two. The transverse movement rollers 31 are all rotatably arranged on the lower side of the machine 2. The transverse movement rollers 31 slide on the transverse movement rail. The linear drive 32 is driven and connected to the machine 2. The controller is driven and connected to the linear drive 32.

[0050] The linear drive 32 is an electric push rod. The linear drive 32 adopts an electric push rod, which has the advantages of low cost and simple layout.

[0051] In this embodiment, the first sensor 46 and / or the second sensor 47 are reflective photoelectric sensors. The first sensor 46 adopts a reflective photoelectric sensor, which has the advantages of simple layout, simple control logic, and low cost. The second sensor 47 adopts a reflective photoelectric sensor, which also has the advantages of simple layout, simple control logic, and low cost. In this embodiment, the first sensor 46 and the second sensor 47 are both reflective photoelectric sensors.

[0052] The distance between the first sensor 46 and the second sensor 47 is 2-8 mm. The distance between the first sensor 46 and the second sensor 47 is 2-8 mm. On the one hand, the cardboard a is easy to dock with the machine 2, and on the other hand, the positioning accuracy of the cardboard a and the machine 2 can be guaranteed. Specifically, the distance between the first sensor 46 and the second sensor 47 is 5 mm. When the distance between the first sensor 46 and the second sensor 47 is 5 mm, the edge position error of the cardboard a is only within 5 mm, the alignment accuracy of the cardboard a and the machine 2 is high, and the alignment speed of the cardboard a is also fast.

[0053] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
