[0024] Corrugated cardboard is available 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. Frequent replacement of the line-touching knife to meet the production requirements of different corrugated cardboard can no longer meet production needs.

[0025] In one aspect, combining 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.

[0026] The first cutter shaft 2 is rotatably disposed on the frame 1 along the length direction of the 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 .

[0027] The second knife shaft 3 is rotatably arranged on the frame 1 along the length direction of the frame 1 and is located directly below the first knife shaft 2, that is, the first knife shaft 2 and the second knife shaft 3 are placed vertically; the second knife seat 31 is arranged on the second knife shaft 3 along the length direction of the second knife shaft 3. The first knife seat 21 and the second knife seat 31 are respectively connected to the first knife shaft 2 and the second knife shaft 3 by welding or fasteners, and can be specifically arranged according to actual needs.

[0028] The thread contact knife 4 is detachably mounted on the first knife seat 21 and the second knife seat 31 by bolts.

[0029] 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 .

[0030] Combination Figure 1 As shown, the driving mechanism 5 is drivingly connected to the first knife shaft 2 and the second knife shaft 3 respectively, and the driving mechanism 5 is configured to drive the first knife shaft 2 and the second knife shaft 3 to rotate, so as to drive the thread contacting knife 4 to rotate.

[0031] Among them, the first knife shaft 2 and the second knife shaft 3 rotate relatively, 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 shaft 2 and the second knife shaft 3 at the same time, and 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, and reduce the impact on the folding straightness and neatness of the corrugated cardboard.

[0032] 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 protrusion is formed on the surface of the punch knife 41, and a depression is formed on the surface of the die knife 42. The protrusion of the punch knife 41 and the depression of the die knife 42 are matched with 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.

[0033] 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 to touch 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 to touch the corrugated cardboard.

[0034] Specifically, the line-touching knife 4 includes a punch knife 41 and a die knife 42, and the punch knife 41 and the die knife 42 are mainly made of alloy steel material. 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, so as to realize 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, so as to realize 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 the corrugated cardboard after the line-touching is convenient to fold.

[0035] 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 line of the corrugated cardboard at the same time to avoid displacement between the line touching knife and the corrugated cardboard, which is beneficial to ensure the folding straightness and neatness of the corrugated cardboard.

[0036] 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 .

[0037] 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.

[0038] When the female die knife 42 on the first knife seat 21 rotates to the line-touching position, the male die knife 41 on the second knife seat 31 rotates to the line-touching position, and when the male die knife 41 on the first knife seat 21 rotates to the line-touching position, the female 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.

[0039] 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.

[0040] Specifically, by making the axis of the first cutter shaft 2 parallel to the axis of the second cutter shaft 3, the first cutter shaft 2 and the second cutter shaft 3 rotate synchronously, so that the operation accuracy of the first cutter shaft 2 and the second cutter shaft 3 is high, and the consistency of the touch line can be ensured.

[0041] Specifically, the first blade shaft 2 and the second blade shaft 3 are both made of steel material, with high structural strength and high running stability.

[0044] Specifically, the first wall panel 11 and the second wall panel 12 are made of metal materials such as steel plates.

[0045] Specifically, the thickness of the steel plate used for the first wall panel 11 and the second wall panel 12 is about 20-35 mm, and illustratively, the thickness of the steel plate is 22 mm, 23 mm, 25 mm, 27 mm or 30 mm. The steel plate has a certain thickness and high structural strength, which can ensure long-term and stable operation of the equipment.

[0046] The cross beam 13 is connected between the first wall panel 11 and the second wall panel 12 by welding or the like; a plurality of groups of cross beams 13 are provided, and the plurality of 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 .

[0047] Exemplarily, four groups of cross beams 13 are provided, and the four groups of cross beams 13 are respectively located at four corners of the first wall panel 11 and the second wall panel 12 .

[0048] The support 14 is arranged at the bottom of the first wall panel 11 and the second wall panel 12. The support 14 can be adjusted horizontally, which is conducive to ensuring the stability of the equipment operation. The support 14 is fixed to the ground by fasteners such as screws, thereby fixing the first wall panel 11 and the second wall panel 12 to the ground.

[0049] In some embodiments of the present application, the frame 1 further includes a first seat bearing 15 and a second seat bearing 16 .

[0050] 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, and the first knife shaft 2 is rotatably arranged on the first wall panel 11 and the second wall panel 12 through the first seat bearings 15; 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 knife shaft 3 is rotatably arranged on the first wall panel 11 and the second wall panel 12 through the second seat bearings 16.

[0051] 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, so that support can be provided for the rotation of the first blade shaft 2 and the second blade shaft 3, 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 the rotation accuracy can be improved.

[0052] Combination Figure 1 , Figure 3 and Fig. 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 .

[0053] The first pulley 51 is fixedly connected to the shaft head of the first cutter shaft 2 through a first expansion sleeve; The second pulley 52 is fixedly connected to the shaft head of the second cutter shaft 3 through a second expansion sleeve; A third pulley 531 is disposed 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 .

[0054] Specifically, the first pulley 51 is fixedly connected to the shaft head of the first cutter shaft 2 through a first expansion sleeve, and the second pulley 52 is fixedly connected to the shaft head of the second cutter shaft 3 through a second expansion sleeve. The first pulley 51 and the second pulley 52 are drivingly 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.

[0055] Specifically, the first pulley 51, the second pulley 52 and the third pulley 531 are connected via a belt 54, or are meshed and driven via gears, which can be specifically configured according to actual needs.

[0056] 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 seat.

[0057] In some embodiments of the present application, Fig.10 As shown, the driving mechanism 5 further includes a fourth pulley 56, Fig.10 The two tangent dotted circles in the figure represent the movement trajectories of the punch knife 41 and the die knife 42.

[0058] 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.

[0059] Among them, from Fig.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 keep synchronous rotation and relative rotation.

[0060] 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 .

[0061] Combination Figure 4 and Figure 8 As shown, in some embodiments of the present application, the line contact assembly also includes an electronic control module, a conveying mechanism 6 and an encoder 7.

[0062] The encoder 7 is electrically connected to the electric control module, and the encoder 7 is configured to detect the running speed of the corrugated cardboard. Exemplarily, the encoder 7 can be a high-precision absolute value encoder.

[0063] The motor 53 is electrically connected to the electric control module, and the electric 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.

[0064] Specifically, by setting the encoder 7, the encoder 7 can detect the running speed of the corrugated cardboard, so that the electric control module can adjust the rotation speed of the motor 53 according to the running speed of the corrugated cardboard.

[0065] 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.

[0066] In some embodiments of the present application, the conveying mechanism 6 includes a paperboard support 61 , a support frame 62 , a rocker plate 63 and a measuring wheel 64 .

[0067] The paperboard support 61 is disposed on the frame 1 , and the paperboard support 61 is used to support the corrugated paperboard.

[0068] The support frame 62 is disposed on the cross beam 13 of the frame 1 , and the rocker plate 63 is connected to the support frame 62 .

[0069] The housing of the encoder 7 is fixed on the rocker plate 63 by screws, and a code disc is arranged inside the encoder 7 .

[0070] The measuring wheel 64 is arranged above the paperboard support 61. The measuring wheel 64 is configured to run synchronously with the corrugated paperboard. A shaft core is formed at the center of the measuring wheel 64. The shaft core is rotatably arranged on the rocker plate 63 through a bearing. The shaft core is fixedly connected to the code disk in the encoder 7. When the shaft core rotates, the code disk can be driven to rotate synchronously. The encoder 7 converts the physical signal (rotation angle) into an electrical signal and transmits it to the control module.

[0071] 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 board.

[0072] 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 .

[0073] 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 a fisheye joint 66. The telescopic member 65 has a telescopic function, so that the measuring wheel 64 can realize the lifting and lowering action as the telescopic member 65 is extended and retracted.

[0074] Specifically, when the telescopic member 65 is extended, the rocker plate 63 is driven to rotate clockwise, thereby reducing the distance between the measuring wheel 64 and the cardboard support 61; when the telescopic member 65 is shortened, the rocker plate 63 is driven to rotate counterclockwise, thereby increasing the distance between the measuring wheel 64 and the cardboard support 61, thereby facilitating adjusting the distance between the measuring wheel 64 and the cardboard support 61 according to the thickness of the corrugated cardboard.

[0075] Exemplarily, the telescopic member 65 may be a cylinder or a spring.
