Description

Technical Field

[0001] This utility model relates to the field of sheet processing, specifically a sheet material guiding mechanism and process tank system between tanks. Background Technology

[0002] In sheet processing, it is necessary to continuously transport the sheets over long distances to ensure material supply and connection for each process stage. Especially in post-processing, the sheets need to pass through multiple consecutive washing tanks, immersion tanks, and other process tanks at intervals, and the sheets need to be guided and transported between the tanks.

[0003] In current equipment, one or more rollers are typically used for guidance between each process tank. However, during the repeated up-and-down movement in and out of the process tanks, the sheet material undergoes repeated turning and high-drop conveying. Traditional roller conveyor structures struggle to precisely control the sheet's position and tension, easily leading to problems such as sheet misalignment and wrinkling during transport. In multi-tank cleaning processes, the sheet needs to enter and exit the cleaning tank multiple times. The insufficient stability of traditional conveyor structures can easily cause the sheet material to vibrate or jam during transport. Utility Model Content

[0004] The purpose of this utility model is to provide a sheet material guiding mechanism and process tank system between tanks, which continuously unfolds and guides the sheet material during repeated entry and exit from the process tank, reducing problems such as offset and wrinkles.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A sheet material guiding mechanism between grooves includes vertically extending and relatively parallel mounting plates. The bottom of the mounting plates is provided with a receiving groove to fix the two. A first roller, a second roller, and a spreading roller are rotatably mounted between the mounting plates and perpendicular to them. The spreading roller is located in the middle of the mounting plates. The first roller and the second roller are symmetrically arranged on the top of the mounting plates relative to the spreading roller. The diameter of the spreading roller is larger than that of the first roller and the second roller. The first roller is located on the side of the sheet material receiving and is driven to rotate by a motor.

[0007] The mounting plate has a side plate extending outward in opposite directions on its bottom side. The side plate extends horizontally and has two lower strip-shaped holes extending horizontally in the same direction. Fixing bolts that cooperate with the lower strip-shaped holes pass through the holes.

[0008] The mounting plate has two vertical strip-shaped holes symmetrically arranged on the bottom side. The vertical strip-shaped holes extend vertically along the height direction of the mounting plate. The side walls at both ends of the receiving groove extend upward and protrude from the groove opening to form ear plates. Double-ended bolts are inserted through the ear plates and are used in conjunction with the vertical strip-shaped holes.

[0009] The diameter of the spreading roller is 20-30cm, and the diameter of the first roller and the second roller is 8-12cm.

[0010] A sensor is installed on the first roller, and the sensor is used to provide feedback on the rotational speed of the first roller.

[0011] The rotation of the second roller is a resistance rotation.

[0012] A bellows is provided above the first roller, and the bellows is arranged side by side with the first roller. The bellows is located on the side of the first roller closer to the material receiving side. A nozzle structure is provided at the bottom of the bellows, and a long and narrow air outlet is provided on the bottom side of the nozzle structure.

[0013] The bellows is connected to a purified air source.

[0014] A mounting beam is fixed between the top sides of two mounting plates. Symmetrical support beams are positioned near the edges of the mounting beam. Each support beam has a horizontally extending upper slotted hole on the side closest to the sheet material. A rectangular block, slidingly fitted along its length, is located within the upper slotted hole. Two rectangular blocks have external screws at their far ends, with locking nuts threaded onto the external screws. An internal screw, coaxial with the external screw, is located at the inner end of each rectangular block, with a locking nut fitted onto the internal screw. A quick-release lever, coaxial with the internal screw, is fixed to the inner end of the internal screw.

[0015] The top of the bellows is symmetrically fixed with mounting brackets. The top of the mounting brackets is provided with a mounting sleeve extending in the same direction as the bellows. The side wall of the mounting sleeve is provided with a threaded tube communicating with its cavity. A tightening bolt is threadedly connected to the threaded tube. The quick-release rod and the mounting sleeve are movably inserted. The inner end of the tightening bolt abuts against the surface of the quick-release rod.

[0016] A process tank system includes tanks arranged sequentially along a linear direction, and a tank sheet guiding mechanism is provided between the tanks.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This solution enables uniform material guiding and auxiliary conveying of sheets between various process tanks. During repeated entry and exit from the tanks, the sheets are continuously unfolded and aligned, allowing for timely forward conveying of thinner, larger sheets and reducing issues such as offset and wrinkles. Furthermore, auxiliary power is installed at the exit points to address the instability and uneven tension issues inherent in traditional conveying structures. Attached Figure Description

[0024] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0025] Example 1: Sheet material guiding mechanism

[0026] This example demonstrates how to guide sheet material between process tanks. Multiple cleaning tanks arranged in a row are used as an application case.

[0027] The main structure includes mounting plates 1 arranged side by side, which provide mounting positions for various guide structures. The mounting plates 1 are parallel and upright, forming a gate-shaped structure. The bottom side of the mounting plates 1 is provided with a side plate 2 that extends outward in opposite directions. The side plate 2 extends horizontally and has two lower strip-shaped holes 3 that extend horizontally in the same direction. Fixing bolts that cooperate with the lower strip-shaped holes 3 pass through the lower strip-shaped holes 3. The two lower strip-shaped holes 3 are symmetrically arranged on the left and right sides and are used to install on the rims of two adjacent cleaning tanks respectively, so as to facilitate straddle installation and fixation.

[0028] The mounting plate 1 has two symmetrical vertical slots 4 on its bottom side, extending vertically along the height of the mounting plate 1. A receiving groove 5 is located at the bottom between the two sides of the mounting plate 1. The receiving groove 5 is used to collect liquids that may drip during transport. The opening of the receiving groove 5 faces upwards, and the width of the receiving groove 5 is not less than the width of the mounting plate 1. The side walls at both ends of the receiving groove 5 extend upwards, protruding from the groove opening to form ear plates 6. Double-ended bolts pass through both the ear plates 6 and the vertical slots 4, and are tightened with nuts to fix the receiving groove 5 to the mounting plate 1, facilitating adjustment of the fixed height of the receiving groove 5.

[0029] A first roller 7, a second roller 8, and a spreading roller 9 are rotatably mounted between the mounting plates 1 via bearings. The first roller 7, the second roller 8, and the spreading roller 9 all extend horizontally and are arranged perpendicularly to the mounting plates 1.

[0030] The spreading roller 9 is installed in a centered position relative to the mounting plate 1, and the spreading roller 9 is installed at the middle position in the height direction of the mounting plate 1.

[0031] The diameter of the spreading roller 9 is 20-30cm. The bottom circumference of the spreading roller 9 is used to wrap around the sheet and fully unfold the sheet to reduce wrinkles, misalignment and other problems.

[0032] The first roller 7 and the second roller 8 are mounted side-by-side at the same height on the upper part of the mounting plate 1. The first roller 7 and the second roller 8 are symmetrically arranged relative to the spreading roller 9. The diameter of the first roller 7 and the second roller 8 is 8-12cm. A mounting platform is fixed on one side of the mounting plate 1, and a motor is fixed on the mounting platform. The output shaft of the motor is connected to the first roller 7 through a reducer to drive the first roller 7, making the first roller 7 an actively rotating roller. In actual use, the first roller 7 is positioned close to the material receiving side of the sheet to pull the sheet in the previous cleaning tank upwards, forming a conveying force in the middle. A sensor is connected to the end of the first roller 7 away from the motor. The rotation speed of the first roller 7 is fed back by a sensor installed under the bearing seat. When there are multiple cleaning tanks, and this material guiding mechanism is installed between each cleaning tank, real-time speed measurement ensures that the rotation speed of each group of first rollers 7 is highly consistent, thereby ensuring that the tension of the sheet conveying is balanced and that there are no problems caused by sudden changes in tension.

[0033] The second roller 8 is a non-powered roller, and appropriate resistance can be added as needed to form a resistance roller. The second roller 8 is located near the washing tank on the discharge side to cooperate with the conveying force behind it to tension the sheet.

[0034] The sheet material is guided by the sequential positioning and coordinated operation of the first roller 7, the second roller 8, and the spreading roller 9. The first roller 7 is positioned near the incoming material washing tank, and the second roller 8 is positioned near the outgoing material washing tank. The sheet material is pulled up from the incoming material washing tank by the first roller 7, passes over the top circumference of the first roller 7, then downwards over the bottom circumference of the spreading roller 9, and finally passes over the top circumference of the second roller 8 before sinking into the adjacent washing tank. After this guiding process, the sheet material can be fully stretched and aligned with the forward conveying direction, thereby reducing wrinkles and misalignment. The resistance rollers provide tension to the subsequent conveying, further improving the tension during conveying and reducing problems caused by slack.

[0035] Since the water may be mixed with some water and suspended impurities on the water surface during the rinsing process in the previous washing tank, an air knife mechanism is set on the upper side of the first roller 7.

[0036] The air knife mechanism includes a mounting beam 11, a support beam 12, an air box 10, and a quick-release rod 13.

[0037] The mounting beam 11 is fixed across the top sides of the two mounting plates 1 to provide support for the entire air duct mechanism.

[0038] The support beams 12 consist of two beams, which are symmetrically fixed to the mounting beam 11 near both ends. The support beams 12 can have an inverted L-shaped structure and are fixed to the support beams 12 by welding profiles.

[0039] The support beam 12 has a horizontally extending upper strip-shaped hole 14. The air box 10 is a long strip-shaped box arranged parallel to the first roller 7. One end of the air box 10 is connected to purified air as the air source, that is, an air inlet pipe is connected to one end of the air box 10. The end of the air inlet pipe away from the air box 10 is connected to an air purifier. The air purifier is an air purifier with an internal exhaust fan and a filter medium set on the air inlet structure. Any air purifier commonly available on the market can be used.

[0040] The bottom side of the air box 10 is provided with a conical air nozzle structure 15. The bottom side of the air nozzle structure 15 is provided with a long and narrow air outlet. The air outlet blows out a strong wind, forming an air knife to blow away the sheet passing through the first roller 7, and the attached moisture and impurities fall into the cleaning pool of the material receiving area.

[0041] The top side of the bellows 10 is symmetrically fixed with mounting brackets 16. The top of the mounting brackets 16 is provided with mounting sleeves 17 extending in the same direction as the bellows 10. The side wall of the mounting sleeves 17 is provided with a threaded tube communicating with its cavity. The threaded tube is internally threaded with a tightening bolt 18. The tightening bolt 18 is a wing bolt structure for easy operation. The inner end of the tightening bolt 18 is used to abut against the quick release rod 13 to control the swing angle of the bellows 10.

[0042] A quick-release rod 13 is provided between the mounting sleeve and the support beam 12. The quick-release rod 13 is movably inserted into the mounting sleeve 17 and is locked and fixed to the mounting sleeve 17 at an adjustable angle by a tightening bolt 18.

[0043] The end of the quick-release lever 13 furthest from the mounting sleeve 17 is a threaded rod 20, and a rectangular block 21 is provided near the end of the threaded rod 20. The width of the rectangular block 21 corresponds to the width of the upper slot 14, and the thickness of the rectangular block 21 is less than the depth of the upper slot 14. Therefore, the rectangular block 21 can only slide along the upper slot 14 and can be stopped and limited circumferentially. Locking nuts are provided on both sides of the rectangular block 21, which are threaded to the threaded rod 20. By tightening the two locking nuts, the mounting bracket 16 is clamped and locked, thus fixing the quick-release lever 13 to the mounting bracket 16. The fixed position is adjustable along the upper slot 14.

[0044] For ease of description, the part located outside the rectangular block 21 is defined as the external screw, and the part located inside the rectangular block 21 is defined as the internal screw.

[0045] Based on the above structure, the bellows 10 can be quickly and easily installed and disassembled via two quick-release rods 13 at both ends. The angle of the bellows 10 blowing air can be adjusted flexibly and conveniently, as can the distance between the bellows 10 and the first roller 7 (the upper sheet). Depending on the angle of the first roller 7 and the adjacent cleaning pool dragging the sheet and the process conditions, the position and angle of the air knife can be adjusted accordingly, thereby effectively removing floating water and impurities without affecting the sheet conveying.

[0046] Example 2:

[0047] The material guiding mechanism of Example 1 is used for conveying between the process tank and the cleaning tank, forming a sheet cleaning process system, the structure of which includes:

[0048] Several cleaning tanks are provided; in this example, there may be four sets of cleaning tanks. The cleaning tanks are rectangular open tanks made of stainless steel, with the top side forming the rim. The spacing between adjacent cleaning tanks is adapted to the width of the material guiding mechanism in Example 1. For ease of description, the four sets of cleaning tanks are designated as Tank 1, Tank 2, Tank 3, and Tank 4 according to the material feeding sequence. Example 1 has three sets of material guiding mechanisms, respectively positioned between Tanks 1, 2, 3, and 4.

[0049] In terms of specific installation method, the bottom side of the mounting plate 1 straddles the edges of the adjacent cleaning pools on both sides of the mounting plate 2, and the fixing bolts in the lower strip hole are fixed to the side wall of the corresponding cleaning pool.

[0050] Adjust the height of the receiving trough 5 so that it is at an appropriate height below the spreading roller 9 and higher than the edge of the cleaning pool.

[0051] After the sheet passes through pool 1, it first passes over the first roller 7 of the material guiding mechanism installed between pool 1 and pool 2, and then passes under the spreading roller 9 and over the second roller 8 in sequence before entering pool 2, thus completing the material guiding between pool 1 and pool 2.

[0052] After passing through Pool 2, the sheet first passes over the first roller 7 of the material guiding mechanism installed between Pool 2 and Pool 3, and then passes under the spreading roller 9 and over the second roller 8 in sequence before entering Pool 3, thus completing the material guiding between Pool 2 and Pool 3.

[0053] After passing through Pool 3, the sheet first passes over the first roller 7 of the material guiding mechanism installed between Pool 3 and Pool 4, then passes under the spreading roller 9 and over the second roller 8 in sequence before entering Pool 4, thus completing the material guiding between Pool 3 and Pool 4.

[0054] Based on the above sheet feeding process, the sheet is sequentially passed through pool 1, pool 2, pool 3, and pool 4 to complete the cleaning process.

[0055] During the material feeding process, the first roller 7 provides intermediate conveying power to the rear, the spreading roller 9 fully unfolds and guides the sheet, and the air knife retains impurities in the previous cleaning pool.
