[0037] Further as Figure 2 As shown, the drive assembly includes a third rotating rod 801, which is movably connected between two side plates 110 on one side of each other. The third rotating rod 801 movably passes through the two moving plates 200. Two gears 803 are provided on the outer wall of the third rotating rod 801. A rack 503 is fixed on one side of the inner wall of the fixed plate 502, and the rack 503 meshes with the gears 803. Four first outer grooves 802 are formed on the outer wall of the third rotating rod 801 in a circular arrangement. The gears 803... Four first engaging strips 806 arranged in a circular pattern are fixed on the inner side wall. The first engaging strips 806 are movably engaged with the first outer groove 802. A first limiting groove 805 is opened on one side of the gear 803. A first limiting ring 804 is fixed on one side of the two moving plates 200 respectively. The first limiting ring 804 is movably connected to the first limiting groove 805. A second servo motor 800 is fixed on one side of the side plate 110. The output end of the second servo motor 800 is fixed to one end of the third rotating rod 801.

[0038] The fixed plate 502 can be moved by the drive components, which in turn drives the baffle 507 to move.

[0039] Further as Figure 2 and Figure 7As shown, two movable plates 200 are movably connected to a second pulley 603 on one side bottom, and two side plates 110 are movably connected to a second rotating rod 601 on one side bottom. The outer wall of the second rotating rod 601 has four circumferentially distributed second outer grooves 808. The outer wall of the second rotating rod 601 is provided with two first pulleys 600. The inner wall of the first pulleys 600 is fixed with four circumferentially distributed second engaging strips 809. A second limiting groove 810 is provided on one side of the first pulleys 600. The two movable plates 200 are fixed to a second limiting ring 811 on one side bottom, and the second limiting ring 811 is movably engaged in the second limiting groove 810. The second rotating rod 601 passes through the two movable plates 200. A belt 604 is movably connected between the first pulley 600 and the second pulley 603. A first servo motor 602 is fixed on one side of one side plate 110, and the output end of the first servo motor 602 is fixed to one side of the second rotating rod 601.

[0040] The third cylinder 605 can move by means of the first pulley 600, the second pulley 603 and the belt 604.

[0041] Further as Figure 2 As shown, mounting blocks 305 are fixed to the top of the two side plates 110 on opposite sides. Two hollow tubes 306 are fixed to one side of each mounting block 305. Connecting strips 304 are movably connected to one side of the outer wall of the two hollow tubes 306. Two limiting posts 303 are fixed between the two connecting strips 304 on opposite sides. A vertical plate 300 is provided on one side of the movable plate 200. Four evenly distributed fixing blocks 301 are fixed to one side of the vertical plate 300. Connecting posts 302 are fixed between two adjacent fixing blocks 301. The two middle fixing blocks 301 are movably connected to the outer walls of the two limiting posts 303. There is a certain distance between the vertical plate 300 and the corresponding inclined plate 202.

[0042] The mounting block 305, connecting strip 304 and limiting post 303 are used to fix the positions of the vertical plates 300 on both sides.

[0043] Further as Figure 2 As shown, a spring 307 is provided around the hollow tube 306. One end of the spring 307 contacts one side of the mounting block 305, and the other end of the spring 307 contacts one side of the connecting strip 304. An external thread is provided on the outer wall of the hollow tube 306 away from the mounting block 305. A nut 308 is movably connected to the outer wall of the hollow tube 306 away from the mounting block 305.

[0044] The distance between the connecting strip 304 and the mounting block 305 can be adjusted by the nut 308, which in turn can adjust the distance between the vertical plate 300 and the inclined plate 202, thus adapting to different support strips.

[0045] This solution has the following working process: When feeding the support bars, the bundle of support bars is first placed horizontally between two inclined plates 202. At this time, several support bars slide down from the inclined plates 202 to the bottom of the vertical plate 300. At this time, several support bars are blocked by the vertical plate 300. Then, the PLC controller 807 controls the external motor 203 to rotate. The rotation of the external motor 203 drives the first rotating rod 204 to rotate. The rotation of the first rotating rod 204 drives the ratchet 205 to rotate. The protrusion on the ratchet 205 pushes one of the support bars, causing the support bar to move out from between the vertical plate 300 and the inclined plate 202 until the support bar moves onto the first placement bar 701 and the second placement bar 703. At this time, the support bar and the first placement bar 701 and the second placement bar are connected. 703 are arranged in a cross shape. Then, the PLC controller 807 controls the third cylinder 605 to start, causing the push plate 606 to move upward. At this time, the two push plates 606 support the support bar. Then, the PLC controller 807 controls the first servo motor 602 to start, causing the belt 604 to rotate. The rotation of the belt 604 drives the push plate 606 to move, which in turn drives the support bar to move to the position of the baffle 507. At this time, the support bar is blocked by the baffle 507. Then, the third cylinder 605 moves downward, causing the push plate 606 to move downward. The first servo motor 602 rotates in the opposite direction, causing the push plate 606 to reset, and start driving the next support bar. During this process, the external motor 203 is in a stopped state. Afterward, the external motor 203 starts, causing the next... The support bars are oriented and moved onto the first placement bar 701 and the second placement bar 703. Then, the third cylinder 605 and the first servo motor 602, following the above steps, move the support bar so that it contacts the side of the previous support bar. This process is repeated until several support bars are evenly distributed on the first placement bar 701 and the second placement bar 703. Then, the second cylinder 506 moves upward, causing the baffle 507 to move upward, thus removing the obstruction to the support bars. Subsequently, the PLC controller 807 and the second servo motor 800 rotate. The rotation of the second servo motor 800 drives the third rotating rod 801 to rotate, which in turn causes the gear 803 to rotate. The rotation of the gear 803 drives the rack 503 to move, and the movement of the rack 503 drives the baffle 503 to move. 7. The movement causes the baffle 507 to move closer to the ratchet 205. At this point, the fixed plate 502 blocks the signal from the infrared sensor 505, which then transmits the signal to the PLC controller 807. The PLC controller 807 controls the second cylinder 506 to move, causing the baffle 507 to move downwards and contact the support bar near the ratchet 205. Then, the PLC controller 807 controls the second servo motor 800 to rotate in the opposite direction, causing the baffle 507 to move further. The baffle 507 pushes several evenly distributed support bars until they move below the extrusion bar 404. Afterward, both the second cylinder 506 and the baffle 507 return to their initial positions, and the ratchet 205 continues to rotate for the next round of support bar position adjustment.Then, the PLC controller 807 controls the first cylinder 401 to move downwards, which in turn drives the extrusion bar 404 to move downwards. The extrusion bar 404 compresses several support bars, ready for the next process.

[0046] When feeding support bars of different lengths, the handwheel 109 is turned manually. The handwheel 109 rotates, which drives the fourth sprocket 108 to rotate. The second chain 107 drives the third sprocket 106 to rotate. The third sprocket 106 rotates, which drives the first bidirectional threaded rod 101 to rotate. At the same time, the second sprocket 105, the first sprocket 103 and the first chain 104 drive the second bidirectional threaded rod 102 to rotate. This causes the two moving plates 200 to move closer or further apart. Then, the support bars can be fed according to the above steps to achieve the feeding of support bars of different widths.

[0047] When positioning white strip rolls of different widths, move the second sliders 901 on both sides, then place the white strip roll between the two sleeve shafts 903, and then move the two second sliders 901 in the opposite direction so that the sleeve shafts 903 position the white strip roll.

[0048] According to the above working process: the inclined plate 202 allows several support bars to slide off; the vertical plate 300 blocks several support bars; the ratchet 205 causes the support bars piled between the vertical plate 300 and the inclined plate 202 to be rotated and reset one by one, thus ensuring that the support bars on the first placement bar 701 and the second placement bar 703 are evenly distributed; and the belt 604, the third cylinder 605, and the push plate 606 ensure that the first placement bar 701 and the second placement bar 703 are evenly distributed. The support bars on the placement bar 703 can be pushed and supported by the push plate 606, thereby moving the support bars to the position of the baffle 507. The baffle 507 can block the support bars, and at the same time, it can also push the support bars. The fixed plate 502 can be moved by the gear 803 and the rack 503, which in turn can move the baffle 507. The first cylinder 401 and the extrusion bar can squeeze and position several support bars, thereby realizing automatic feeding of support bars, which is convenient to operate and improves the feeding efficiency of support bars.

[0049] By setting the first bidirectional threaded rod 101 and the second bidirectional threaded rod 102, the distance between the two moving plates 200 can be adjusted, thereby enabling the feeding of support bars of different lengths.

[0050] The connecting bar 304 can be moved by the nut 308, thereby adjusting the distance between the vertical plate 300 and the inclined plate 202 to accommodate support bars of different widths.

[0051] Further as Figure 2 As shown, the two movable plates 200 are respectively fixed with a first placement strip 701 close to each other on one side, a support column 702 is fixed on one side of the top surface of the support platform 100, a second placement strip 703 is fixed on the top surface of the support column 702, and an inclined strip 700 is fixed in the middle of the outer side wall of the two positioning columns 201. The length of the inclined strip 700 is the same as the length of the inclined plate 202.

[0052] The placement strips are designed so that the support strips removed from the inclined plate 202 can fall on the first placement strip 701 and the second placement strip 703.

[0053] Further as Figure 2 As shown, a side strip 405 is fixed to one side of the L-shaped rod 403, and two docking posts 406 are fixed to the bottom surface of the side strip 405. The top surface of the extrusion strip 404 is fixed to the bottom surface of the two docking posts 406.

[0054] The side strip 405 and the connecting post 406 are designed to fix the extrusion strip 404 to the L-shaped rod 403.

[0055] Further as Figure 2 As shown, a third cylinder 605 is fixed to the top surface of the belt 604, and a push plate 606 is fixed to the output end of the third cylinder 605. Two movable plates 200 are respectively fixed to a first guide rail 500 on opposite sides. A first slider 501 is fixed to one side of the inner wall of the fixed plate 502, and the first slider 501 is movably engaged with the first guide rail 500. Two pressure rollers 504 are respectively fixed to opposite sides of the two movable plates 200, and the outer walls of the two pressure rollers 504 contact the top surface of the rack 503. Infrared sensors 505 are respectively fixed to opposite sides of the two movable plates 200. A PLC controller 807 is fixed to one side of the support platform 100. The external motor 203, the first servo motor 602, the second servo motor 800, the first cylinder 401, the second cylinder 506, the third cylinder 605, and the infrared sensor 505 are electrically connected to the PLC controller 807.

[0056] The push plate 606 allows the support bars that fall on the first placement bar 701 and the second placement bar 703 to be lifted up, and then the support bars are moved by the transmission of the belt 604.

[0057] Further as Figure 2 and Figure 5As shown, a first bidirectional threaded rod 101 is movably connected between the top of one side of the two side plates 110, close to each other. The non-threaded portion of the outer side wall of the first bidirectional threaded rod 101 passes through the other side plate 110. A third sprocket 106 is fixed to one side of the outer side wall of the first bidirectional threaded rod 101. A fourth sprocket 108 is movably connected to one side of the other side plate 110. A handwheel 109 is fixed to one side of the outer side wall of the fourth sprocket 108. A second chain 107 is movably connected between the third sprocket 106 and the fourth sprocket 108. The movable plates 200 are movably connected to the outer wall of the first bidirectional threaded rod 101. A second sprocket 105 is fixed on the other side of the outer wall of the fourth sprocket 108. The two side plates 110 are movably connected between the bottom of one side of each other. A first sprocket 103 is fixed at a non-threaded position on one side of the outer wall of the second bidirectional threaded rod 102. A first chain 104 is movably connected between the first sprocket 103 and the second sprocket 105. The two movable plates 200 are movably connected to the outer wall of the second bidirectional threaded rod 102.

[0058] By setting the first bidirectional threaded rod 101 and the second bidirectional threaded rod 102, the two moving plates 200 can move closer or further apart, thereby feeding support bars of different lengths.

[0059] Further as Figure 2 As shown, two second guide rails 900 are fixed on one side of the lower top surface of the support platform 100. Two second sliders 901 are movably connected between the two second guide rails 900. A stabilizing plate 902 is fixed on the top surface of the second sliders 901. A sleeve shaft 903 is movably connected between the two stabilizing plates 902 on one side close to each other.

[0060] The spacing between the two stabilizing plates 902 can be adjusted by the second slider 901, thereby positioning white strip rolls of different widths. The white strip rolls can be positioned by the sleeve shaft 903.

[0061] In summary: When feeding the support bars, the bundles of support bars are first placed horizontally between two inclined plates 202. Several support bars slide down from the inclined plates 202 to the bottom of the vertical plate 300, where they are blocked. Then, the PLC controller 807 controls the external motor 203 to rotate. The external motor 203 rotates the first rotating rod 204, which in turn rotates the ratchet 205. The protrusion on the ratchet 205 pushes one of the support bars, causing it to move out from between the vertical plate 300 and the inclined plate 202 until it moves onto the first placement bar 701 and the second placement bar 703. At this point, the support bars are arranged in a cross shape with the first placement bar 701 and the second placement bar 703. Then P... The LC controller 807 controls the third cylinder 605 to start, causing the push plate 606 to move upward. At this time, the two push plates 606 support the support bar. Then, the PLC controller 807 controls the first servo motor 602 to start, causing the belt 604 to rotate. The rotation of the belt 604 drives the push plate 606 to move, which in turn drives the support bar to move to the position of the baffle 507. At this time, the support bar is blocked by the baffle 507. Then, the third cylinder 605 moves downward, causing the push plate 606 to move downward. The first servo motor 602 rotates in the opposite direction, causing the push plate 606 to reset, and the next support bar is driven. During this process, the external motor 203 is in a stopped state. Afterward, the external motor 203 starts, causing the next support bar to be adjusted in direction and driven to the first position. The first support bar is placed on the first placement bar 701 and the second placement bar 703. Then, the third cylinder 605 and the first servo motor 602 drive the support bar according to the above steps, so that the support bar contacts the side of the previous support bar. Repeat the above steps until several support bars are evenly distributed on the first placement bar 701 and the second placement bar 703. Then, the second cylinder 506 moves upward, causing the baffle 507 to move upward, removing the obstruction to the support bar. Subsequently, the PLC controller 807 rotates the second servo motor 800. The rotation of the second servo motor 800 drives the third rotating rod 801 to rotate, which in turn causes the gear 803 to rotate. The rotation of the gear 803 drives the rack 503 to move. The movement of the rack 503 drives the baffle 507 to move, so that the baffle 507 moves close to the ratchet 2. At position 05, the fixed plate 502 blocks the signal from the infrared sensor 505. The infrared sensor 505 transmits the signal to the PLC controller 807. The PLC controller 807 controls the second cylinder 506 to move, causing the baffle 507 to move down and contact the support bar near the ratchet 205. Then, the PLC controller 807 controls the second servo motor 800 to rotate in the opposite direction, causing the baffle 507 to move. The baffle 507 pushes several evenly distributed support bars to move until the support bars move below the extrusion bar 404. After that, the second cylinder 506 and the baffle 507 return to their initial positions, and the ratchet 205 continues to rotate for the next round of support bar position adjustment. Then, the PLC controller 807 controls the first cylinder 401 to move down.This, in turn, causes the extrusion bar 404 to move downwards, pressing several support bars together, ready for the next process.

[0062] When feeding support bars of different lengths, the handwheel 109 is turned manually. The handwheel 109 rotates, which drives the fourth sprocket 108 to rotate. The second chain 107 drives the third sprocket 106 to rotate. The third sprocket 106 rotates, which drives the first bidirectional threaded rod 101 to rotate. At the same time, the second sprocket 105, the first sprocket 103 and the first chain 104 drive the second bidirectional threaded rod 102 to rotate. This causes the two moving plates 200 to move closer or further apart. Then, the support bars can be fed according to the above steps to achieve the feeding of support bars of different widths.

[0063] When positioning white strip rolls of different widths, move the second sliders 901 on both sides, then place the white strip roll between the two sleeve shafts 903, and then move the two second sliders 901 in the opposite direction so that the sleeve shafts 903 position the white strip roll.

[0064] The external motor 203, the first cylinder 401, the infrared sensor 505, the second cylinder 506, the first servo motor 602, the third cylinder 605, the second servo motor 800, and the PLC controller 807 can be purchased from the market and are mature technologies in this field, which have been fully disclosed. Therefore, they will not be described again in the specification.

[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
