The two feeder heads are driven by the main machine and cannot adjust the speed ratio with the main machine according to the length of the paper, and automatically adjust the alignment accuracy, which leads to a large gap when the paper is broken during production, and the alignment accuracy is not high. There is a positioning gauge on the alignment chain. If the length of the paper produced is greater than the interval of the positioning gauge, the positioning gauge will directly press the tail of the paper, resulting in the machine can only produce products within the interval of the positioning gauge. The machine has poor adaptability to the length of paper and cannot meet the needs of flexible production in modern society. Summary of the invention

[0022] Step 1: Start the power supply, enter the conveying control system, adjust the starting position of the tissue paper feeder head and the card paper feeder head, start the tissue paper conveyor belt, card paper conveyor belt, and transition conveyor belt, and prepare to feed paper.

[0023] Step 2: Input the length of the paper, the operating speed of the host, the transmission speed of the transition conveyor belt and the spacing of the papers, so that the conveying control system calculates the speed ratio of the first and second servo drive devices to the host speed according to its parameters, so that it controls the paper feeding speed of the tissue paper feeder head and the card paper feeder head; the conveying control system calculates the time required for the tissue paper to reach its set distance according to the paper feeding speed of the tissue paper feeder head, the operating speed of the host and the spacing of the papers, and adjusts the start-up time of the second servo drive device.

[0031] There are four cardboard chains, each of which is equipped with a stop block to ensure that the cardboard is always aligned and is not affected by the deformation of the cardboard corners. It also ensures that different papers are evenly stressed when limiting, avoiding deformation caused by uneven stress on the paper.

[0032] The retaining gauge seat of the present invention is adjustable, so that it can be adjusted according to the deviation of the retaining gauge seat between adjacent cardboard chains, so that the retaining gauge seat on the cardboard chain is kept in the same radial position, avoiding the situation where the retaining gauge seat tilts when aligning the paper due to the difference in the front and rear positions.

[0045] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] Reference Figure 1 As shown, a high-precision automatic cardboard mounting machine includes a facial paper feed rack 1, a cardboard feed rack 2, a facial paper conveying mechanism 3, a cardboard conveying mechanism 4, a pressing mechanism 5, a facial paper feeder head 6, a cardboard feeder head 7, a first servo drive device, a second servo drive device, an alignment drive device, a conveying control system, and a frame.

[0047] The facial paper feeding rack 1, the card paper feeding rack 2, the card paper conveying mechanism 4 and the pressing device 5 are arranged in sequence along the paper conveying direction. The first and second servo drive devices and the alignment drive device are respectively electrically connected to the conveying control system.

[0048] Reference Figure 1 , Figure 4 , Figure 6 As shown, the paper feeding mechanism 4 includes a paper conveyor belt 41 and a paper aligning unit 42. The paper aligning unit 42 includes a first paper chain 43, a second paper chain 44, a third paper chain 45 and a fourth paper chain 46. The paper conveyor belt is arranged on a frame. The first, second, third and fourth paper chains 43, 44, 45 and 46 are arranged in parallel and at the end of the paper conveyor belt 41. A first sprocket shaft and a second sprocket shaft are arranged at the end of the frame for rotating back and forth. The first sprocket shaft is fixedly provided with a first driving sprocket corresponding to the first, second, third and fourth paper chains 43, 44, 45 and 46. The second sprocket shaft is fixedly provided with a first driven sprocket corresponding to the first, second, third and fourth paper chains 43, 44, 45 and 46, so that the first, second, third and fourth paper chains 43, 44, 45 and 46 are respectively tensioned on the first driving sprocket and the first driven sprocket.

[0049] Reference Figure 6 , Fig. 9As shown, in the present invention, the number of chain links of the first, second, third and fourth paper jam chains 43, 44, 45 and 46 is preferably 40, and at least two stop gauge assemblies 47 are arranged on the first, second, third and fourth paper jam chains 43, 44, 45 and 46. The present invention preferably adopts two stop gauge assemblies, and a stop gauge assembly is arranged every 20 sections of the first, second, third and fourth paper jam chains 43, 44, 45 and 46. The stop gauge assembly 47 includes a stop gauge seat 471 and a stop gauge block 472. The stop gauge block 472 is arranged on the stop gauge seat 471, and the stop gauge seat 471 is fixedly connected to the first, second, third and fourth paper jam chains 43, 44, 45 and 46. Fig.10 , Fig.11 As shown; when the paper jam is input to the first, second, third and fourth paper jam chains 43, 44, 45 and 46 through the paper jam conveyor belt, the stop block 472 on the first, second, third and fourth paper jam chains 43, 44, 45 and 46 limits the front edge of the paper jam. Compared with the prior art, two paper jam chains are used, and stop blocks are provided on the chains. However, due to the dampness of the paper jam, it is inevitable that the corners will be warped and deformed, resulting in the paper jam being unable to be normally limited on the stop block, making it impossible to align the paper. Moreover, when the paper is relatively thin, or the span of the paper is large, when it is limited by the stop block, the paper is prone to slight deformation, thereby affecting the subsequent process. The present invention uses four paper jam chains. Chains 43, 44, 45, 46, when the paper jam has no defects, the leading edge of the paper jam is limited to the first, second, third, and fourth paper jam chains 43, 44, 45, 46. When the paper jam is warped and deformed, the first and fourth paper jam chains 43, 46 cannot limit the leading edge of the paper jam, but the distance between the second and third paper jam chains 44, 45 is smaller than the distance between the first and fourth paper jam chains 43, 46, so that the second and third paper jam chains 44, 45 still limit the leading edge of the paper jam, thereby ensuring that the paper jam always remains aligned and is not affected by the warping and deformation of the paper jam, and ensuring that different papers are subjected to uniform force when limiting, thereby avoiding deformation of the paper due to uneven force.

[0050] Reference Figure 6 , Fig.11As shown, preferably, a pair of strip grooves 473 are provided at the bottom of the stop gauge block 472, which are fixedly connected to the stop gauge seat 471 by screws passing through the strip grooves 473. Compared with the prior art in which the stop gauge and the chain are fixedly arranged, the paper jam stop gauge cannot be adjusted. Due to slight differences in the chain itself and the tolerances accumulated by other matching parts or the tolerances accumulated over a long period of time, the front and rear position deviation of the product reaches more than 0.6 mm. The movable range of the stop gauge seat 471 in the present invention is less than 4 mm. The stop gauge seat 471 is moved along the chain lock by loosening the chain lock, and is adjusted according to the deviation of the adjacent stop gauge seats 471 to keep the stop gauge seats 471 on the first, second, third and fourth paper jam chains 43, 44, 45 and 46 in the same radial position to avoid the situation in which the paper is tilted due to the front and rear position difference of the stop gauge seat 471.

[0051] Reference Figure 2 , Figure 3 As shown, the facial paper feeding mechanism 3 includes a facial paper conveyor belt 31, a facial paper aligning part 32, a first facial paper chain 33 and a second facial paper chain 34 of the facial paper aligning part 32, the facial paper conveyor belt 31 is obliquely arranged above the jamming paper conveyor belt 41, the first and second facial paper chains 33 and 34 are arranged in parallel and obliquely arranged at the upper end of the facial paper conveyor belt 31, and a second driving sprocket, a second driven sprocket and a third driven sprocket are respectively arranged on both sides of the frame 9, and the first and second facial paper chains 33 and 34 are tensioned on the first driving sprocket, the second driven sprocket and the third driven sprocket.

[0052] Reference Figure 2-Figure 6 As shown, the alignment drive device preferably adopts a servo motor, and the two ends of the first sprocket shaft are respectively connected to the second active sprocket for transmission, and the end of the first sprocket shaft is fixedly connected to the output shaft of the servo motor. The first sprocket shaft is driven to rotate by the alignment drive device, so that the first, second, third and fourth paper chains 43, 44, 45 and 46 rotate synchronously. At the same time, the first sprocket shaft is linked to the second active sprocket to rotate, so that the first and second surface paper chains 33 and 34 move synchronously with the first, second, third and fourth paper chains 43, 44, 45 and 46.

[0053] The alignment drive device preferably adopts a servo motor, which drives the first and second tissue paper chains to run synchronously through the alignment drive device. The third driven sprocket is higher than the second driving sprocket and the second driven sprocket, so that a trumpet opening is formed between the head ends of the first and second tissue paper sprockets 33 and 34 and the tissue paper conveyor belt 31, so that the tissue paper can pass smoothly between the first and second tissue paper chains and the tissue paper conveyor belt.

[0054] The number of chain links of the first and second paper chains 33, 34 of the present invention is preferably 40, and at least two gauge claws 35 are provided on the first and second paper chains 33, 34, and one gauge claw 35 is provided for every 20 links of the first and second paper chains 33, 34. At least two gauge claws 47 are provided on the first and second paper chains 33, 34, so that the gauge claws 47 limit the leading edge of the facing paper on the gauge claws.

[0055] Reference Figure 1 , Figure 7 , Fig. 9 As shown, a transition conveyor belt 36 is arranged between the upper end of the tissue paper conveyor belt 31 and the top of the tissue paper feeding rack 1, the tissue paper feeder head 6 is arranged above the tissue paper feeding rack 1, the card paper feeding rack 2 is arranged at the head end of the card paper conveyor belt 41, the card paper feeder head 7 is arranged above the card paper feeding rack 2, and the first lifting assembly and the second lifting assembly are respectively arranged in the tissue paper feeding rack 1 and the card paper feeding rack 2.

[0056] The first lifting component includes a paperboard, a first conveying shaft, a second conveying belt, a lifting drive device, a first lifting chain, a second lifting chain, a third lifting chain, and a fourth lifting chain. The left end of the first conveying shaft is provided with a first driving sprocket and a second driving sprocket, the right end of the first conveying shaft is provided with a third driving sprocket and a fourth driving sprocket, and both ends of the second conveying shaft are provided with a first driven sprocket and a second driven sprocket. The paperboard is arranged at the lower part of the tissue paper feeding rack, one end of the first and second lifting chains are respectively wound around the first and second driven sprockets and fixedly connected with the first and fourth driving sprockets, and the other ends are respectively fixedly connected with the left side of the paperboard, one end of the third and fourth lifting chains are respectively fixedly connected with the second and third driving sprockets, and the other ends are respectively fixedly connected with the right side of the placing plate, and the tissue paper pile is stacked on the paperboard, and the second transmission shaft is driven to rotate by the lifting drive device, so that the first, second, third, and fourth lifting chains drive the paperboard to move up and down, thereby driving the tissue paper pile to rise and fall.

[0057] The surface paper feeder head and the bottom paper feeder head in the embodiment of the present invention are prior art, and the prior art is a feeder head with Chinese patent publication number CN203652881U, which will not be repeatedly described here.

[0058] Reference Figure 1-Figure 9As shown, the conveying control system of the present invention calculates the speed ratio of the first and second servo drive devices to the host speed according to the length of the paper and the rotation speed of the transition conveyor belt, thereby controlling the paper feeding speed of the tissue paper feeder head 6 and the card paper feeder head 7. The conveying control system controls the first servo drive device to drive the tissue paper feeder head to absorb the tissue paper and send it to the transition conveyor belt 36. At the same time, the lifting drive device drives the first, second, third, and fourth lifting chains to contract, so that the tissue paper on the paperboard is driven to rise to the bottom of the tissue paper feeder head, and the lifting drive device stops accordingly, thereby realizing automatic paper suction, paper feeding, and paper lifting. After the tissue paper enters the transition conveyor belt 36, it is sent to the tissue paper conveyor belt 31.

[0059] The rotation speed of the first and second servo drive devices is proportional to the rotation speed of the transition conveyor belt 36, so that the distance between any adjacent tissue papers fed into the transition conveyor belt 36 remains consistent, thereby avoiding deviation of tissue papers and cardboard during transportation due to the different rotation speeds between the first and second servo drive devices, resulting in inaccurate alignment between them and affecting the mounting quality.

[0060] The rotation speed of the first and second servo drive devices is inversely proportional to the length of the paper, so that the rotation speed of the first servo drive device, the second servo drive device, and the transition conveyor belt 36 decreases as the length of the paper increases, thereby controlling the paper feeding speed of the surface paper feeder 6 and the card paper feeder head 7 according to the size of different papers.

[0061] In the present invention, a transition conveyor belt is provided between the facial paper feed rack and the facial paper conveyor belt, so that a certain distance is formed between the facial paper feed rack and the card paper feed rack. In order to ensure the consistent transmission between the facial paper and the card paper, it is necessary to control the start-up sequence between the first and second servo drive devices to make up the distance between the facial paper feed rack 1 and the card paper feed rack 2. Therefore, the conveying control system calculates the time required for the facial paper to reach the set distance according to the paper feeding speed of the facial paper feeder head 6, the operating speed of the host computer and the distance between the facial paper and the paper jam, thereby controlling the start-up sequence between the first and second servo drive devices. When the facial paper reaches the distance set by the conveying control system within the set time, the conveying control system then starts the second servo drive device, so that the second servo drive device drives the paper jam feeder head 7 to feed the paper jam on the paper jam feeding rack 2 onto the paper jam conveyor belt 41, ensuring that the positions of the facial paper and the paper jam are consistent, thereby compensating for the distance difference between the facial paper and the paper jam during the conveying process, avoiding the situation where the paper jam arrives at the paper jam alignment part first and the facial paper does not arrive at the facial paper alignment part 32, thereby causing paper leakage, affecting subsequent processes.

[0062] Reference Figure 1-Figure 3As shown, the first pre-pressing roller 21 and the second pre-pressing roller 22 are rotatably arranged on one side of the paper feeding rack 2 adjacent to the paper conveyor belt 41, a shunt pipe 211 is arranged above the first pre-pressing roller 21, a guide pipe 212 is vertically arranged on the upper part of the shunt pipe 211, a glue pump is arranged at one end of the shunt pipe 211, and a plurality of glue nozzles are arranged at intervals along the axis of the shunt pipe 211. Under the action of the glue pump, the glue enters the shunt pipe 211 through the guide pipe 212, so that the glue flows out from the glue nozzle and is applied to the first pre-pressing roller 21, a pre-pressing drive device is installed on the surface of the second pre-pressing roller 22 at the end thereof, and the pre-pressing drive device preferably adopts a motor, and the second pre-pressing roller 22 is driven by the pre-pressing drive device, so that the second pre-pressing roller 22 drives the paper jam to move, so that the paper jam passes between the first and second pre-pressing rollers 21 and 22 and enters the paper jam conveyor belt 41, and the first pre-pressing roller 21 rotates with the movement of the paper jam, so that the first pre-pressing roller 21 applies glue to the surface of the paper jam on the paper jam feeding rack 2, and the paper jam conveyor belt 41 conveys it forward.

The first and second side gauge synchronous belts 483 and 484 are respectively tensioned on the first and second synchronous wheels 487 and 488. The diameter of the first synchronous wheel 487 is larger than the diameter of the second synchronous wheel 488, so that the first and second side gauge synchronous belts 487 and 488 are wide in front and narrow in the back, and the first and second synchronous drive devices 485 and 486 respectively drive the first and second side gauge synchronous belts 487 and 488 to rotate.

One end of the adjustment rod 492 is rotatably provided on both sides of the paper jam conveyor belt 31, and the other end is threadedly connected to the adjustment seat 491. By rotating the adjustment rod 492, the first and second side gauge synchronous belts 485, 486 can be made close to or far from each other, so that the spacing between the first and second side gauge synchronous belts can be adjusted according to paper of different widths.

[0065] A paper jam side gauge mechanism 37 is provided on the paper conveyor belt 31 , and the structure of the paper jam side gauge mechanism 37 is the same as that of the paper jam side gauge mechanism 38 .

After being corrected, the cardboard and the facial paper continue to be conveyed forward by the cardboard conveyor belt 41, so that the cardboard and the facial paper enter the cardboard paper alignment part and the facial paper alignment part respectively, and the edge of the cardboard is restricted by the blocking block 472 of the first, second, third and fourth cardboard chains 43, 44, 45 and 46 to align them, and the gauge claws 35 of the first and second facial paper chains 33 and 34 are used to limit the edge of the cardboard.

[0071] Step 2: Input the length of the paper, the operating speed of the host, the transmission speed of the transition conveyor belt and the spacing of the papers, so that the conveying control system calculates the speed ratio of the first and second servo drive devices to the host speed according to its parameters, so that it controls the paper feeding speed of the tissue paper feeder head and the card paper feeder head; the conveying control system calculates the time required for the tissue paper to reach the set distance according to the paper feeding speed of the tissue paper feeder head, the operating speed of the host (the default is 30m / mim if not set) and the spacing of the papers, so as to adjust the start time of the second servo drive device.

[0072] Step 3: The conveying control system controls the first servo drive device to start according to the given parameters, so that it drives the tissue paper feeder head to feed the tissue paper on the tissue paper feed rack onto the transition conveyor belt, and the transition conveyor belt feeds the tissue paper forward to the tissue paper conveyor belt, and the tissue paper feeder head continuously feeds the tissue paper onto the transition conveyor belt within the time when the tissue paper reaches the paper jam position; when the start-up time of the second servo drive device reaches the time set by the conveying control system, it starts the second servo drive device, so that the second servo drive device drives the paper jam on the paper jam feed rack to be fed onto the paper jam conveyor belt.

[0073] Step 4: When the paper is fed into the paper conveyor belt, the first and second pre-pressing rollers are used to apply glue to the surface of the paper.

[0074] Step 5: The face paper and the glued card paper enter the face paper side gauge mechanism and the card paper side gauge mechanism respectively. Between the adjusted side gauges, the left and right positions of the face paper and the card paper are restricted by the side gauges, and the paper is adjusted to the required position.

[0075] Step 6: After the left and right positions of the facial paper and cardboard are adjusted, they enter the facial paper alignment section and the cardboard alignment section respectively. The leading edge of the facial paper is limited to the gauge claws of the first and second facial paper chains, and the leading edge of the cardboard is limited to the gauge blocks of the first, second, third and fourth cardboard chains, so that they limit the conveying positions of the facial paper and cardboard respectively. The paper is determined by the paper leakage detection device, and the conveying control system starts the alignment drive device to drive the gauge claws and the gauge blocks to move. After a certain conveying adjustment, the leading edge of the facial paper enters the gauge seat at the intersection of the facial paper conveyor belt and the cardboard conveyor belt. The facial paper and the cardboard are limited by the gauge blocks at the same time, so that the two papers are completely aligned and enter the pre-pressing mechanism together for mounting.

[0076] Step 7: The paper pre-pressed by the pre-pressing mechanism enters the pressing channel, and is stacked after being pressed firmly by the pressing conveyor belt and the receiving conveyor belt.
