[0068] Corrugated cardboard comes in many forms, such as three-layer board and five-layer board. The flute shape of each corrugated cardboard is different. In order to ensure that the corrugated cardboard is easier to fold after touching the line, the line-touching machine has different knife types accordingly. Frequent replacement of the line-touching knife to meet the production requirements of different corrugated cardboards can no longer meet production needs.

[0069] In one aspect, combined Figures 1 to 9 As shown, an embodiment of the present disclosure provides a thread-touching assembly, which includes a frame 1, a first knife shaft 2, a first knife seat 21, a second knife shaft 3, a second knife seat 31, a thread-touching knife 4 and a driving mechanism 5.

[0070] The first cutter shaft 2 is rotatably disposed on the machine frame 1 along the length direction of the machine frame 1 , and the first cutter seat 21 is disposed on the first cutter shaft 2 along the length direction of the first cutter shaft 2 .

[0071] The second blade shaft 3 is rotatably disposed on the frame 1 along the length direction of the frame 1 and is located directly below the first blade shaft 2, that is, the first blade shaft 2 and the second blade shaft 3 are placed vertically; the second blade seat 31 is disposed on the second blade shaft 3 along the length direction of the second blade shaft 3. The first blade seat 21 and the second blade seat 31 are respectively connected to the first blade shaft 2 and the second blade shaft 3 by welding or fasteners, and the specific configuration can be based on actual needs.

[0072] The line contact knife 4 is detachably mounted on the first knife seat 21 and the second knife seat 31 by bolts.

[0073] It should be noted that, during the process of the line-touching knife 4 touching the line of the corrugated cardboard, the corrugated cardboard is located between the two line-touching knives 4 .

[0074] Combine Figure 1 As shown, the driving mechanism 5 is respectively connected to the first cutter shaft 2 and the second cutter shaft 3, and the driving mechanism 5 is configured to drive the first cutter shaft 2 and the second cutter shaft 3 to rotate, so as to drive the thread-touching knife 4 to rotate.

[0075] Among them, the first knife shaft 2 and the second knife shaft 3 rotate relative to each other, and the line-touching knife 4 on the first knife seat 21 and the second knife seat 31 touches the corrugated cardboard at the line-touching position between the first knife seat 2 and the second knife seat 3 at the same time. The entire width of the line-touching knife 4 on the first knife seat 21 and the second knife seat 31 contacts the corrugated cardboard at the same time, and the line-touching knife 4 moves synchronously with the corrugated cardboard, which can avoid displacement between the line-touching knife 4 and the corrugated cardboard, reducing the impact on the folding straightness and neatness of the corrugated cardboard.

[0076] In some embodiments of the present application, Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the line-touching knife 4 includes a punch knife 41 and a die knife 42. A convex portion is formed on the surface of the punch knife 41, and a concave portion is formed on the surface of the die knife 42. The convex portion of the punch knife 41 and the concave portion of the die knife 42 are adapted to each other; the punch knife 41 and the die knife 42 are both provided on the first knife seat 21 and the second knife seat 31.

[0077] And when the punch knife 41 on the first knife seat 21 rotates to the touch line position, the die knife 42 on the second knife seat 31 rotates to the touch line position at the same time to touch the corrugated cardboard; when the die knife 42 on the first knife seat 21 rotates to the touch line position, the punch knife 41 on the second knife seat 31 rotates to the touch line position at the same time to touch the corrugated cardboard.

[0078] Specifically, the line-touching knife 4 includes a punch knife 41 and a die knife 42. The punch knife 41 and the die knife 42 are mainly made of alloy steel. When the punch knife 41 on the first knife seat 21 rotates to the line-touching position, the die knife 42 on the second knife seat 31 rotates to the line-touching position at the same time, thereby realizing the line-touching operation on the corrugated cardboard; when the die knife 42 on the first knife seat 21 rotates to the line-touching position, the punch knife 41 on the second knife seat 31 rotates to the line-touching position at the same time, thereby realizing the line-touching operation on the corrugated cardboard. By touching the line of the corrugated cardboard with the punch knife 41 and the die knife 42, the line-touching pressure on the corrugated cardboard can be increased, the line-touching effect is good, and it is convenient to fold the corrugated cardboard after touching the line.

[0079] In addition, the punch knife 41 and the die knife 42 can be used for corrugated cardboards with different flute shapes at the same time. When touching the line, the punch knife 41 and the die knife 42 can touch the corrugated cardboard at the same time, avoiding displacement between the line touching knife and the corrugated cardboard, which is beneficial to ensure the folding straightness and neatness of the corrugated cardboard.

[0080] In some embodiments of the present application, the number of the first tool seat 21 and the number of the second tool seat 31 are both two, the two first tool seats 21 are symmetrically arranged about the first tool axis 2, and the two second tool seats 31 are symmetrically arranged about the second tool axis 3.

[0081] Specifically, by setting the number of the first tool seat 21 and the second tool seat 31 to two, the two first tool seats 21 are symmetrically arranged about the first tool axis 2, and the two second tool seats 31 are symmetrically arranged about the second tool axis 3; the two line-touching knives 4 on the first tool seat 21 are respectively the punch knife 41 and the die knife 42, and the two line-touching knives 4 on the second tool seat 31 are respectively the punch knife 41 and the die knife 42, so that the punch knife 41 and the die knife 42 on the first tool seat 21 are symmetrical about the first tool axis 2, and the punch knife 41 and the die knife 42 on the second tool seat 31 are symmetrical about the second tool axis 3.

[0082] When the die knife 42 on the first knife seat 21 rotates to the line-touching position, the punch knife 41 on the second knife seat 31 rotates to the line-touching position. When the punch knife 41 on the first knife seat 21 rotates to the line-touching position, the die knife 42 on the second knife seat 31 rotates to the line-touching position, and the corrugated cardboard is touched alternately. After touching the line, the corrugated cardboard is given a folding direction, which makes it easier to fold the corrugated cardboard and improves the neatness of stacking and folding.

[0083] In some embodiments of the present application, the axis of the first cutter shaft 2 is parallel to the axis of the second cutter shaft 3, and the first cutter shaft 2 and the second cutter shaft 3 rotate synchronously.

[0084] Specifically, by aligning the axis of the first cutter shaft 2 and the axis of the second cutter shaft 3 in parallel, the first cutter shaft 2 and the second cutter shaft 3 rotate synchronously, so that the operation precision of the first cutter shaft 2 and the second cutter shaft 3 is high, and the consistency of the touch line can be ensured.

[0085] Specifically, the first blade shaft 2 and the second blade shaft 3 are both made of steel material, with high structural strength and high operating stability.

[0086] Combine Figure 2 As shown, the frame 1 includes a first wall panel 11 , a second wall panel 12 , a crossbeam 13 and a support 14 .

[0087] The first wall panel 11 and the second wall panel 12 are rectangular plate-shaped structures, and the first wall panel 11 and the second wall panel 12 are arranged opposite to each other. A gap for placing the first blade shaft 2 and the second blade shaft 3 is provided between the first wall panel 11 and the second wall panel 12 .

[0088] Specifically, the first wall panel 11 and the second wall panel 12 are made of metal materials such as steel plates.

[0089] Specifically, the thickness of the steel plate used for the first wall panel 11 and the second wall panel 12 is about 20 to 35 mm. For example, the thickness of the steel plate is 22 mm, 23 mm, 25 mm, 27 mm, or 30 mm. The steel plate has a specific thickness and high structural strength, which can ensure long-term and stable operation of the equipment.

[0090] The cross beam 13 is connected between the first wall panel 11 and the second wall panel 12 by welding or other means; there are multiple groups of cross beams 13, and the multiple groups of cross beams 13 connect the first wall panel 11 and the second wall panel 12 together to form a high-precision and stable support for the first wall panel 11 and the second wall panel 12.

[0091] Exemplarily, four groups of cross beams 13 are provided, and the four groups of cross beams 13 are respectively located at the four corners of the first wall panel 11 and the second wall panel 12 .

[0092] The support 14 is provided at the bottom of the first wall panel 11 and the second wall panel 12. The support 14 can be adjusted horizontally to ensure stable operation of the equipment. The support 14 is fixed to the ground with fasteners such as screws, thereby fixing the first wall panel 11 and the second wall panel 12 to the ground.

[0093] In some embodiments of the present application, the frame 1 further includes a first seat bearing 15 and a second seat bearing 16 .

[0094] The first seat bearings 15 are arranged in pairs, and the two pairs of first seat bearings 15 are fixedly arranged on the first wall panel 11 and the second wall panel 12 respectively. The first blade shaft 2 is rotatably arranged on the first wall panel 11 and the second wall panel 12 through the first seat bearings 15;

[0095] The second seat bearings 16 are arranged in pairs, and the two pairs of second seat bearings 16 are fixedly arranged on the first wall panel 11 and the second wall panel 12 respectively. The second blade shaft 3 is rotatably arranged on the first wall panel 11 and the second wall panel 12 through the second seat bearings 16.

[0096] Specifically, by setting the first seat bearing 15 and the second seat bearing 16, the first blade shaft 2 is rotatably arranged on the first wall panel 11 and the second wall panel 12 through the first seat bearing 15, and the second blade shaft 3 is rotatably arranged on the first wall panel 11 and the second wall panel 12 through the second seat bearing 16. This can provide support for the rotation of the first blade shaft 2 and the second blade shaft 3, reduce the friction between the first blade shaft 2, the second blade shaft 3, the first wall panel 11 and the second wall panel 12, and improve the rotation accuracy.

[0097] Combine Figure 1 、 Figure 3 and Figure 9 As shown, in some embodiments of the present application, the driving mechanism 5 includes a first pulley 51 , a second pulley 52 and a motor 53 .

[0098] The first pulley 51 is fixedly connected to the shaft head of the first cutter shaft 2 through a first expansion sleeve;

[0099] The second pulley 52 is fixedly connected to the shaft head of the second cutter shaft 3 through a second expansion sleeve;

[0100] A third pulley 531 is provided on the output shaft of the motor 53 , and the third pulley 531 is drivingly connected to the first pulley 51 and the second pulley 52 .

[0101] Specifically, the first pulley 51 is fixedly connected to the shaft head of the first cutter shaft 2 through the first expansion sleeve, and the second pulley 52 is fixedly connected to the shaft head of the second cutter shaft 3 through the second expansion sleeve. The first pulley 51 and the second pulley 52 are driven and connected with the third pulley 531. The motor 53 drives the first pulley 51 and the second pulley 52 to rotate by driving the third pulley 531, thereby driving the first cutter shaft 2 and the second cutter shaft 3 to rotate synchronously, thereby realizing power transmission.

[0102] Specifically, the first pulley 51, the second pulley 52 and the third pulley 531 are connected through a belt 54, or are meshed and driven by gears, and the specific configuration can be made according to actual needs.

[0103] Specifically, the motor 53 is a permanent magnet synchronous servo motor 53, which has high line contact control accuracy and high line contact efficiency. The motor 53 is installed on the first wall panel 11 or the second wall panel 12 through a motor 53 base.

[0104] In some embodiments of the present application, Figure 10 As shown, the driving mechanism 5 further includes a fourth pulley 56, Figure 10The two tangent dotted circles in the figure represent the movement trajectories of the punch knife 41 and the die knife 42.

[0105] The fourth pulley 56 is rotatably arranged on the first wall panel 11, and the first pulley 51, the second pulley 52, the third pulley 531 and the fourth pulley 56 are synchronously driven and connected with the belt 54, and the fourth pulley 56 is located between the first pulley 51 and the second pulley 52, the third pulley 531 is located between the first pulley 51 and the second pulley 52, and the fourth pulley 56 and the third pulley 531 are respectively located on both sides of the second pulley 52.

[0106] Among them, from Figure 10 It can be seen intuitively in the figure that the fourth pulley 56 mainly plays a steering role, so that the first pulley 51 and the second pulley 52 maintain synchronous rotation and relative rotation.

[0107] In some embodiments of the present application, the driving mechanism 5 further includes a reducer 55 , which is connected to the motor 53 and is used to adjust the rotation speed of the motor 53 .

[0110] The motor 53 is electrically connected to the electronic control module. The electronic control module receives the running speed of the corrugated cardboard detected by the encoder 7 and controls the rotation speed of the motor 53 according to the running speed.

[0111] Specifically, by providing the encoder 7 , the encoder 7 can detect the running speed of the corrugated cardboard, so that the electronic control module can adjust the rotation speed of the motor 53 according to the running speed of the corrugated cardboard.

[0112] In some embodiments of the present application, the running speed of the corrugated cardboard is consistent with the running speed of the punch knife 41 and the die knife 42, which can reduce or avoid the displacement between the corrugated cardboard and the line-touching knife and improve the accuracy of the line-touching.

[0117] A measuring wheel 64 is positioned above the cardboard support 61 and is configured to operate synchronously with the corrugated cardboard. A shaft core is formed at the center of the measuring wheel 64 and is rotatably mounted on the rocker plate 63 via a bearing. The shaft core is fixedly connected to the code disk within the encoder 7. Rotation of the shaft core drives the code disk to rotate synchronously. The encoder 7 converts the physical signal (rotation angle) into an electrical signal, which is then transmitted to the control module.

[0118] Specifically, knurling is formed on the surface of the measuring wheel 64 to increase the surface friction coefficient of the measuring wheel 64 and avoid slipping between the measuring wheel 64 and the corrugated cardboard.

[0119] In some embodiments of the present application, the rocker plate 63 is rotatably connected to the support frame 62 , the conveying mechanism 6 further includes a telescopic member 65 , a connecting seat 621 is formed on the support frame 62 , and a positioning seat is formed on the rocker plate 63 .

[0120] One end of the telescopic member 65 is rotatably connected to the connecting seat 621 of the support frame 62, and the other end of the telescopic member 65 is rotatably connected to the positioning seat 631 on the rocker plate 63 through the fisheye joint 66. The telescopic member 65 has a telescopic function, so that the measuring wheel 64 can be lifted and lowered as the telescopic member 65 is extended and retracted.

[0121] Specifically, when the telescopic member 65 is extended, it drives the rocker plate 63 to rotate clockwise, reducing the distance between the measuring wheel 64 and the cardboard support 61; when the telescopic member 65 is shortened, it drives the rocker plate 63 to rotate counterclockwise, increasing the distance between the measuring wheel 64 and the cardboard support 61, making it easier to adjust the distance between the measuring wheel 64 and the cardboard support 61 according to the thickness of the corrugated cardboard.

[0122] Exemplarily, the telescopic member 65 may be a cylinder or a spring.
