Description

Technical Field

[0001] The present invention belongs to the technical field of corrugated board production and processing, and particularly relates to an auxiliary guiding device for a corrugated board production line. Background Art

[0002] Corrugated board is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper sandwich and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. The actual performance of corrugated board depends on three factors: the characteristics of the core paper and cardboard, and the structure of the carton itself. Corrugated paper is used relatively frequently in the existing market, so the demand for it is relatively large. Therefore, when producing corrugated board, it is usually produced and processed through an assembly line production method. During the production process, in order to ensure the continuous processing of the corrugated board production line, an auxiliary guiding device is needed to assist in pulling the semi-finished corrugated board so that it can be continuously transmitted on a series of production lines, improving production efficiency.

[0003] In the prior art, during the process of using an auxiliary guiding device to guide and transmit the semi-finished corrugated board, most of the guiding devices have a single function at the upper end and can only perform the function of cardboard transmission. Such an auxiliary guiding device has some drawbacks;

[0004] First of all, when producing corrugated board through an assembly line, the cardboard needs to be delivered to each processing point at a fixed point and time. However, when the ordinary auxiliary guiding device guides, it does not have the function of positioning and centering, resulting in possible processing misalignment due to position deviation when the corrugated board is transmitted to the next processing line through the auxiliary guiding device, and then resulting in a large deviation in processing dimensions, causing waste of resources. Secondly, the heights of the machines used on different corrugated paper production lines are different. The ordinary auxiliary guiding device does not have a height adjustment function during use, resulting in jamming of the corrugated paper during transmission using such a guiding device due to the height difference between the machines, and the processing needs to be interrupted, reducing the processing efficiency. Thirdly, when the machine specifications of the front and rear processing lines are different, the heights between them may also be different, with a certain height difference. The ordinary auxiliary guiding device does not have an angle adjustment function and will still cause the corrugated board to be unable to be transmitted, resulting in the inability to connect and use the equipment, reducing the flexibility of the device.

[0005] Therefore, it is very necessary to invent an auxiliary guiding device for a corrugated board production line, which can automatically center and correct according to the size of the corrugated board, and at the same time can realize free adjustment of height and angle, facilitating guiding and transmission on a modern corrugated board production line.

[0019] The technical effects and advantages of the present invention:

[0020] 1. The present invention sets up an automatic correction guiding mechanism and a sensing component. During the transfer process of corrugated cardboard, when the front end of the cardboard passes through the irradiation range of the infrared sensor of the sensing component and blocks it, the infrared sensor is triggered and sends a command to the control panel to start the electric push rod. The third traction roller is pushed by the first moving frame to squeeze both sides of the corrugated cardboard to center it. And under the rolling of the third traction roller, the cardboard continues to be transferred, and the front end enters the inner side of the first traction roller whose spacing has already been adjusted according to the width of the cardboard. Through the combined traction of the first traction roller, the second traction roller and the third traction roller, automatic correction and centering transfer are realized, which is convenient for accurate positioning during later cutting and processing. And after the corrugated cardboard leaves the irradiation of the infrared sensor, the electric push rod is controlled by the control panel to return to its original position, waiting for the next piece of corrugated cardboard to enter the transfer and then repeating this operation, reducing the loss amount and reducing resource waste;

[0021] 2. The present invention sets up a lifting mechanism. The third motor is started to drive the first one-way lead screw to push the movable rod to move on the adjusting bracket, and then the cross link is folded crosswise. During this process, the cross link drives the support frame to perform lifting adjustment, which is convenient for docking with machines of different heights in different production lines, and is convenient for folding and shrinking when not in use, improving the convenience of equipment use;

[0022] 3. The present invention sets up an angle adjustment mechanism. When there is a certain height difference between the height of the machine at the rear end and the machine at the front end on the production line, the fourth motor is started to drive the second one-way lead screw to rotate, and then the threaded connection connecting plate slides in the connection slot, and then the second moving frame is pushed to slide in the fifth limit chute. While sliding, the support bar pushes the adjusting bracket to rotate on the support base, and then the inclination angle of the entire auxiliary guiding device is adjusted, which is convenient for docking and use between the production line machine equipment with a height difference between the front and the back, improving the flexibility of the device use.

[0037] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] The present invention provides an auxiliary guiding device for a corrugated cardboard production line as shown in Figures 1-11 , which includes a support base 1 and an adjustment bracket 2. It is characterized in that: an automatic correction guiding mechanism 3, a sensing component 4, a lifting mechanism 9 and an angle adjustment mechanism 10 are respectively installed on the upper end of the adjustment bracket 2 from top to bottom. One end of the support base 1 is hinged to the adjustment bracket 2;

[0039] The automatic correction guiding mechanism 3 includes a support frame 301 installed on the top of the adjustment bracket 2. First limit chutes 302 are opened on both sides of the top of the support frame 301. A connecting frame 303 is slidably connected to the inner walls of the two first limit chutes 302. A traction frame 304 is fixedly provided on the top of the two connecting frames 303. A plurality of first traction rollers 305 are rotatably connected to the inner walls of the two traction frames 304 at equal intervals. A plurality of second traction rollers 306 are rotatably connected to the inner wall of the support frame 301 at equal intervals. Second limit chutes 307 are opened on both sides of one end of the top of the support frame 301. First moving frames 308 are slidably connected to the inner walls of the two second limit chutes 307. Two third traction rollers 309 are rotatably connected to the inner walls of one ends of the two first moving frames 308. Electric push rods 310 are installed on one side of the inner walls of the two second limit chutes 307. The output ends of the two electric push rods 310 are respectively fixedly connected to one side of the two first moving frames 308. Screw holes 312 are opened at the lower edges of one side of the two connecting frames 303. A bidirectional lead screw 313 is rotatably connected to the middle position of the bottom of the support frame 301. The outer walls of both ends of the bidirectional lead screw 313 are respectively threadedly connected to the inner walls of the two screw holes 312;

[0040] The sensing component 4 includes a baffle 401, a mounting base 402 and an infrared sensor 403 installed on the top of the support frame 301;

[0041] During use, the entire auxiliary guiding device is moved and carried to the space between the equipment of the corrugated cardboard production line by moving the supporting base 1. After docking it, according to the width requirements of each batch of corrugated cardboard, the first motor 311 is controlled on the control panel to drive the bidirectional lead screw 313 to rotate, thereby driving the two connecting frames 303 to slide relative to each other in the first limiting chute 302, and then adjusting the distance between the traction frames 304 so that the distance between the first traction rollers 305 at the upper end is exactly the same as the width of the corrugated cardboard. Then, when the corrugated cardboard is transferred from the previous processing equipment to the support frame 301, it moves to the second traction roller 306 at the front end of the support frame 301 by its own inertia, and is transferred under the drive of the second traction roller 306. When the end of the corrugated cardboard moves through the sensing range of the sensing component 4, an instruction is sent to the control panel through the infrared sensor 403 to activate the electric push rods 310 in the second limiting chute 307, so that the two electric push rods 310 extend and retract synchronously to push the first moving frame 308 to slide relative to each other in the second limiting chute 307, thereby driving the third traction rollers 309 at both ends to approach and contact both sides of the corrugated cardboard, centering and squeezing it. Moreover, the third traction rollers 309 rotate on the first moving frame 308. After centering and squeezing the corrugated cardboard, under the traction and transfer of the first traction roller 305, the outer walls on both sides of the corrugated cardboard continue to be transferred along the rolling of the third traction rollers 309. While continuously moving forward, the outer walls at the front ends on both sides just contact the outer walls of the first traction rollers 305 with the adjusted distance. Under the combined contact rotation and traction of the first traction roller 305, the second traction roller 306, and the third traction roller 309, it is smoothly transferred, and is centered and transferred to the next processing line for processing operations. When the tail of the corrugated cardboard leaves the irradiation range of the infrared sensor 403, the electric push rods 310 contract, so that the first moving frame 308 drives the third traction rollers 309 to return to their original positions. After the next corrugated cardboard is transferred, this operation is repeated, reducing the probability of cardboard deviation, improving the processing effect, and reducing resource waste;

[0042] Further, as shown in the attached drawings of the specification Figure 1 and 4 The support frame 301 is installed at the edge of one side of the top of the support frame 301, the installation base 402 is installed at the edge of the other side of the top of the support frame 301, the infrared sensor 403 is installed on one side of the installation base 402, and the two electric push rods 310 are both electrically connected to the infrared sensor 403. During the transfer of the corrugated cardboard, when passing through the irradiation path of the infrared sensor 403 on one side of the installation base 402, it blocks the infrared sensor 403, thereby triggering the infrared sensor 403 to send an instruction to control the electric push rod 310 to extend through the control panel, facilitating the normal operation of the automatic correction guiding mechanism 3. When the sensing component 4 is not triggered, the infrared sensor 403 irradiates on the baffle 401, making it not easily blocked by external objects and causing false touches.

[0043] As shown in the attached specification Figure 6 As shown in the figure, a first motor 311 is installed on one side of the outer wall of the support frame 301, and one end of the bidirectional lead screw 313 passes through the outer wall on one side of the support frame 301 and is fixedly connected to the output end of the first motor 311. According to the width requirement of the corrugated cardboard in each batch, the first motor 311 is started to rotate the bidirectional lead screw 313, which is then threadedly connected to the threaded hole 312 on the connecting frame 303, adjusting the distance between the connecting frame 303 and the traction frame 304, and further adjusting the distance between the first traction rollers 305 to the width dimension of the corrugated cardboard, making it convenient to contact the outer wall of the corrugated cardboard and rotate to guide the transmission of the corrugated cardboard;

[0044] Furthermore, as shown in the attached specification Figure 7 As shown in the figure, a synchronous pulley 5 is fixedly provided at one end of each second traction roller 306. A synchronous belt strip 6 is inserted and connected to the inner wall at one end of the support frame 301, and the inner wall of the synchronous belt strip 6 meshes with the outer wall of each synchronous pulley 5 respectively. A second motor 7 is installed on the other side of the outer wall of the support frame 301, and the other end of one of the second traction rollers 306 passes through the outer wall on one side of the support frame 301 and is fixedly connected to the output end of the second motor 7. Buffer grooves 8 are provided on both sides at the top of the adjusting bracket 2. When the second traction roller 306 transmits the corrugated cardboard, the second motor 7 is started, and under the meshing drive of the synchronous pulley 5 and the synchronous belt strip 6, all the second traction rollers 306 rotate synchronously to transmit the corrugated cardboard;

[0045] Furthermore, as shown in the attached specification Figures 8-9 As shown in the figure, the lifting mechanism 9 includes cross linkages 901 rotatably connected to the two side edges of the inner wall of the adjusting bracket 2. Third limiting chutes 902 are provided on the other side of the two sides of the inner wall of the adjusting bracket 2.

A third motor 904 is installed on the inner wall at one end of the adjusting bracket 2, and one end of the first one-way lead screw 903 is fixedly connected to the output end of the third motor 904. One end of the bottom of the two cross linkages 901 is respectively rotatably connected to the two sides of the inner wall of the adjusting bracket 2 and can only rotate and cannot displace.

[0046] A reinforcing rod 905 is rotatably connected to the middle position between the two cross linkages 901. A movable rod 906 is rotatably connected to the end area between the two cross linkages 901, and the outer wall of the first one-way lead screw 903 is threadedly connected to the inner wall of the movable rod 906. One end of the bottom of the two cross linkages 901 is respectively rotatably connected to a movable block 907, and the outer walls of the two movable blocks 907 are respectively slidably connected to the inner walls of the two third limiting chutes 902. The other end of the bottom of the two cross linkages 901 is respectively rotatably connected to the two movable blocks 907, and through the movable blocks 907, it can not only rotate but also displace horizontally left and right on the inner wall of the adjusting bracket 2.

[0047] One end of the top of each of the two cross links 901 is rotatably connected to a movable bracket 908, and the other end of the top of each of the two cross links 901 is rotatably connected to a fixed bracket 909. The tops of the two fixed brackets 909 are respectively fixedly connected to the two corners at the bottom of the support frame 301. Fourth limiting chutes 910 are formed on both sides of the bottom of the support frame 301, and the outer walls of one end of the two movable brackets 908 are respectively slidably connected to the inner walls of the two fourth limiting chutes 910. When the height of the auxiliary guiding device needs to be adjusted, the third motor 904 is started, so that the first one-way lead screw 903 rotates, and then is threadedly connected to the movable rod 906 rotatably connected between the two cross links 901, so that the movable rod 906 moves on the first one-way lead screw 903, and then drives the cross links 901 to cross and contract. Since the cross links 901 are connected to the support frame 301 through the fixed brackets 908, when the cross links 901 cross and expand and contract, the support frame 301 can be adjusted up and down, which is convenient for docking with different corrugated paper production line equipment. And during the adjustment, since the bottoms of the two cross links 901 are respectively rotatably connected to the fixed brackets 908 and the movable brackets 909, and the movable brackets 909 slide in the fourth limiting chutes 910, and the cross links 901 slide in the third limiting chutes 902 through the movable blocks 907, there is no movement interference during its up and down adjustment, and the adjustment can be carried out smoothly;

[0048] Further, as shown in the Figures 10-11 specification appendix, the angle adjustment mechanism 10 includes fifth limiting chutes 1001 formed on both sides of the top of the support base 1.

While the second moving frames 1002 slide in the fifth limiting chutes 1001, the support bars 1003 rotatably connected to their upper ends are rotatably connected to the bottom of the adjustment bracket 2.

[0049] A connecting plate 1005 is fixedly connected between the bottoms of two second moving frames 1002 through the inner walls of two connecting grooves 1004 respectively.

Universal wheels 11 are installed at the four corners of the bottom of the support base 1. When encountering machine equipment with different heights on both sides of the corrugated cardboard production line, after adjusting the height of the equipment through the lifting mechanism 9, then start the fourth motor 1007 to drive the second one-way lead screw 1006 to rotate. The second one-way lead screw 1006 is threadedly connected with the connecting plate 1005 to drive the two second moving frames 1002 to slide in the fifth limit sliding groove 1001, and then push the support strip 1003 to push the adjusting bracket 2, so that it rotates on the support base 1, and then adjust the inclination angle of the upper structure, so that it is convenient to be docked with equipment with a height difference, and improve the flexibility of equipment use.
