The path recognition device comprises a height recognition mechanism and an angle recognition mechanism, wherein the height recognition mechanism can detect the height change of the base material, and the angle recognition mechanism can detect the approximate value change of the vertical line on the surface of the base material. The floating pressing device comprises an upper pressing roller 5 arranged on a frame 12 and a lower pressing roller 6 arranged on the upper pressing roller 5, wherein the upper pressing roller 5 can move up and down, the lower pressing roller 6 can move up and down along with the upper pressing roller 5, and meanwhile, the lower pressing roller 6 can rotate by taking the axial lead of the upper pressing roller 5 as the center.

As can be seen from fig. 3, the wave-shaped substrate has periodically changed peaks and valleys, so long as the distance between the path recognition device and the floating pressing device is one period, the path recognition device can provide the height change data of the substrate surface for the upper press roller 5 and the lower press roller 6, so that the movement of the upper press roller 5 and the lower press roller 6 conforms to the shape of the substrate surface, and the foam bonding of the wave-shaped substrate is realized. When the base material is a sheet or a coiled material, the surface of the base material has no change in height, and the upper press roller 5 and the lower press roller 6 can normally attach foam, and only the conveying mechanism of the foam needs to be changed.

In order to be able to adjust the distance between the path recognition device and the floating press-fit device, a slide rail 4 is fixedly mounted on the frame 12, a slide block 41 which can be moved along the slide rail 4 is mounted on the slide rail 4, and a first screw 42 which can be rotated and is parallel to the slide rail 4 is mounted on the frame 12. The first screw 42 is in threaded engagement with the slide 41, and when the first screw 42 is rotated, the threads can drive the slide 41 to move on the slide rail 4. To facilitate sliding the first screw 42, a handle 43 is fixedly mounted to the end of the first screw 42.

As shown in fig. 4, the angle recognition mechanism includes a rotating shaft 33 rotatably mounted on the slider 32 and a vertical rod 35 fixed to one end of the rotating shaft 33 near the edge of the substrate, the vertical rod 35 being perpendicular to the rotating shaft 33. The vertical rod 35 is provided with a guiding unit matched with the edge of the substrate. Specifically, the guiding unit includes a cross bar 36, two first guide wheels 37 and one second guide wheel 38, the cross bar 36 is perpendicular to the vertical bar 35, the vertical bar 35 passes through the middle of the cross bar 36, and the cross bar 36 can slide along the vertical bar 35. The two first guide wheels 37 are symmetrically arranged at two ends of the cross bar 36 with the vertical rod 35 as a center, and the two first guide wheels 37 can rotate. The second guide wheel 38 is rotatably mounted at one end of the vertical rod 35, and the other end of the vertical rod 35 is sleeved with a first spring 39 capable of pushing the cross rod 36 to the second guide wheel 38.

When the device is used, two first guide wheels 37 are placed on the upper surface of a base material, and a second guide wheel 38 is placed on the lower surface of the base material, and under the action of the first springs 39, the first guide wheels 37 and the second guide wheels 38 can be tightly attached to the surface of the base material. As shown in fig. 3, since the rotating shaft 33 is disposed on the slider 32, and the slider 32 can only move up and down along the column 3, when the substrate moves, the wavy surface of the substrate can act on the first guide wheel 37 and the second guide wheel 38, causing the first guide wheel 37 and the second guide wheel 38 to move up and down along the surface of the substrate, and further, the rotating shaft 33 and the slider 32 are moved along the column 3, and in the process, the displacement sensor 31 records the displacement amount of the rotating shaft 33.

Because the vertical rod 35 is fixed on the rotating shaft 33, and the rotating shaft 33 can rotate, the two first guide wheels 37 can keep fit with the surface of the substrate, and the vertical rod 35 is positioned on the middle vertical line of the two first guide wheels 37, and at this time, the vertical rod 35 is approximately positioned on the vertical line of a point on the edge of the wavy substrate corresponding to the rotating shaft 33. And the rotating shaft 33 is further provided with an angle sensor 34 for detecting an angle change of the rotating shaft 33. Therefore, the angle sensor 34 can approximately obtain the angle of the vertical line of a point on the edge of the substrate corresponding to the rotation axis 33.

Specifically, two parallel guide rods 51 are fixed to the frame 12, and the guide rods 51 are vertically downward and parallel to the upright 3. The two guide rods 51 are movably sleeved with guide sleeves 52, and limiting blocks 511 for preventing the guide sleeves 52 from being separated are arranged at the bottoms of the guide rods 51. The two guide sleeves 52 are fixedly connected with a frame 53 which is in an inverted U shape, and two ends of an upper roller shaft 57 of the upper press roller 5 are respectively rotatably arranged on the frame 53. The driving frame 53 moves along the guide rod 51 to move up and down the upper press roller 5. In order to conveniently control the height of the upper press roller 5, a first motor 56 is fixedly installed on the frame 12, the output end of the first motor 56 is connected with a second screw rod 55, the second screw rod 55 is parallel to the guide rod 51, meanwhile, a fixing frame 54 is also fixed on the frame 12, the second screw rod 55 is rotatably installed on the fixing frame 54, and the second screw rod 55 is in threaded fit with the frame 53, so that the first motor 56 can drive the frame 53 to move along the second screw rod 55 by driving the second screw rod 55 to rotate, namely, the height adjustment of the upper press roller 5 is realized.

In order to form a pressing force between the upper pressing roller 5 and the lower pressing roller 6, a shaft sleeve 62 is movably sleeved at the end part of the upper roller shaft 57, a first gear 63 and a fixed block 64 are fixedly sleeved on the shaft sleeve 62, the fixed block 64 and the first gear 63 are fixed, and when the first gear 63 rotates around the upper roller shaft 57, the fixed block 64 also rotates together. The slide bar 65 is inserted in the fixed block 64 movably, and the slide bar 65 can move along the fixed block 64 but cannot rotate. The bottom of the slide bar 65 is fixed with a bearing seat 66, and the lower roll shaft 61 of the lower press roll 6 is mounted on the bearing seat 66. Thus, when the first gear 63 rotates, the lower press roller 6 can be rotated by the slide bar 65. An adjusting nut 67 is mounted on one end of the sliding rod 65 away from the bearing seat 66 in a threaded manner, and a second spring 671 is sleeved on the sliding rod 65 between the adjusting nut 67 and the fixed block 64. Under the action of the second spring 671, the sliding rod 65 drives the lower pressing roller 6 to move towards the upper pressing roller 5, so that a pressing force is provided, and the upper pressing roller 5 and the lower pressing roller 6 press the foam and the base material.

In order to conveniently control the rotation of the first gear 63, a second gear 68 meshed with the first gear 63 is rotatably mounted on the frame 53, a second motor 69 is fixed on the frame 53, and the second motor 69 drives the second gear 68 to rotate through a bevel gear set 691. The second motor 69 can drive the first gear 63 to rotate through the second gear 68, so that the sliding rod 65 drives the lower pressing roller 6 to rotate around the axis of the upper pressing roller 5, and the rotating angle is the same as the data of the angle sensor 34.

As shown in fig. 7, the second gear 68 drives the first gear 63 to rotate, so that the slide bar 65 drives the lower press roller 6 to rotate, so that the line between the center points of the lower press roller 6 and the upper press roller 5 substantially coincides with the perpendicular line at the contact point of the base material.

In order to reduce the resistance when the conveying mechanism conveys the substrate, the upper press roller 5 and the lower press roller 6 can actively rotate. The third motor 8 is fixedly arranged on the frame 53, an output shaft of the third motor 8 is connected with the upper roll shaft 57 through a belt transmission mechanism 81, the upper roll shaft 57 is connected with the lower roll shaft 61 through the belt transmission mechanism 81, and therefore the third motor 8 can drive the upper press roll 5 and the lower press roll 6 to rotate at the same speed through the belt transmission mechanism 81. The belt drive 81 generally includes a belt, a driving pulley, and a driven pulley. Because the upper press roller 5 and the lower press roller 6 are tensioned by the second spring 671, a certain floating space exists between the upper press roller 5 and the lower press roller 6, and a tension adjusting mechanism is added to the belt to ensure the stability of transmission. The tension adjusting mechanism is a lot of in the prior art, and is not described in detail here.

The conveying mechanism can have two forms according to the base materials.

For the wave-shaped base material, at least two avoidance grooves 11 can be formed in the conveying table 1, and four avoidance grooves 11 are formed in the embodiment. A rotatable conveying roller 7 is mounted on the base 73 below the avoidance groove 11, and the conveying roller 7 can be driven by a servo motor. The conveying roller 7 is provided with a crest portion 71 and a trough portion 72 in the circumferential direction, which are fitted to the wavy structure of the base material. When the conveying roller 7 rotates, the crest 71 can pass through the escape groove 11 and move the crest 71 of the base material from below the base material, and the crest 71 of the base material is driven to move on the conveying table 1. The conveying roller 7 can push the substrate if the substrate weight is large. If the substrate is lighter, the limit upper cover 9 can be installed on the conveying table 1, the limit upper cover 9 can cover the substrate from the upper side of the conveying roller 7, and the limit upper cover 9 can be matched with the conveying table 1 to form upper and lower limit on the substrate. Thus, when the conveying roller 7 drives the substrate to move, the substrate is not tilted, and the substrate is smoothly pushed in.

For sheet substrates or webs, conventional round rollers may be used for transport.

When in use, the utility model is characterized in that: the substrate is placed on the conveyor table 1, and the first guide wheel 37 is placed on the upper surface edge of the substrate, and the second guide wheel 38 is placed on the lower surface edge of the substrate, after which the adjustment is made according to the shape of the substrate.

If the substrate is wavy, the position of the slider 41 on the first screw rod 42 needs to be adjusted according to the periodicity thereof, so that the distance between the rotating shaft 33 and the upper press roller 5 is matched with the wavy characteristic of the substrate, and the substrate is pushed by using the conveying roller 7 of the embodiment. If the substrate is a sheet or a roll, the substrate may be transported by a conventional transport means without adjusting the position of the slider 41.

After the substrate is normally conveyed, the guide unit plays a role, the floating block 32 ascends and descends along with the surface of the substrate, the vertical rod 35 also rotates along with the rotation, the displacement sensor 31 and the angle sensor 34 collect data and feed back to the first motor 56 and the second motor 69, and the ascending and descending of the upper press roller 5 and the rotation of the axle center of the press roller 5 above the lower press roller 6 are respectively controlled, so that the upper press roller 5 and the lower press roller 6 can apply a pressing resultant force in the vertical line direction of foam and the substrate, dislocation of the foam and the substrate is avoided, and wrinkling of the foam is avoided or reduced.
