Description

Technical Field

[0001] This invention relates to the field of material coating technology, and in particular to a multifunctional coating composite equipment for tarpaulins. Background Technology

[0002] As a functional material widely used in warehousing, transportation, construction, agriculture and other fields, tarpaulin is mainly used to cover and protect goods, sites and equipment. Its functions include windproof, rainproof, sunproof, dustproof and a certain degree of flame retardancy and anti-aging. In the production and processing of tarpaulin, coating and laminating machine is one of the key pieces of equipment. By coating the base fabric with a specific coating and laminating it with other functional films or substrates, the tarpaulin is given the required properties. When operating a coating laminating machine, the base fabric is first introduced into the equipment through an unwinding device. After being positioned by guide rollers, it enters the coating area. At this time, the coating in the trough is transferred to the surface of the base fabric through coating components such as anilox rollers. Then, the base fabric coated with the coating enters the drying device for curing treatment. It is then laminated with other substrates at the laminating rollers and finally wound up into a finished product by a winding device.

[0003] However, in existing technologies, due to the inherent characteristics of the coating itself, high-viscosity coatings have poor flowability in the trough. When high-viscosity coatings settle or accumulate in the trough due to poor flowability, resulting in inconsistent coating amounts in the contact areas of the anilox roller, the amount of coating adsorbed by the mesh openings on the surface of the anilox roller will vary significantly during rotation. The mesh openings in areas with more coating contact are fully filled, and coating may even overflow from the mesh openings. Conversely, the mesh openings in areas with less coating contact cannot be completely filled, leaving some mesh openings in a semi-empty state. This can lead to problems during the coating process of the covering mesh base fabric. The coating on the base fabric surface is prone to localized over-thickness or under-thickness. Furthermore, due to poor flow of the coating in the feed trough, stagnant zones are formed in the contact area of ​​the anilox roller, making it impossible to evenly replenish the coating onto the surface of the anilox roller. This further exacerbates the uneven distribution of the coating. The coating in the stagnant zone remains relatively stationary for a long time and is prone to solidification or agglomeration due to its high viscosity. When the anilox roller contacts this area, it not only fails to obtain a sufficient and uniform amount of coating but may also carry the solidified or agglomerated coating particles to the surface of the base fabric, forming localized protrusions or defects and affecting the appearance quality of the product. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional covering mesh coating composite equipment to solve the problem mentioned in the background art where high-viscosity coatings have poor flowability in the material tank, resulting in uneven coating adsorption by the anilox roller.

[0005] The present invention provides a multifunctional covering mesh coating and composite equipment, which adopts the following technical solution: A multifunctional tarpaulin coating and laminating equipment includes: frame; An anilox roller is mounted on the frame; The back roller is positioned above the anilox roller; The feed trough is movably positioned below the anilox roller; The lifting mechanism, mounted on the frame, is used to control the up-and-down movement of the material trough, and also includes: A feeding mechanism is set in a trough. The feeding mechanism includes a horizontal frame plate fixed in the trough and multiple sets of first and second feed ports equidistantly opened on the horizontal frame plate. The first and second feed ports are arranged alternately. A reciprocating plate is slidably connected in the trough. The reciprocating plate slides in contact with the horizontal frame plate. The reciprocating plate has channels that correspond one-to-one with the first feed ports. A circulation mechanism is installed on the material trough. The circulation mechanism includes a housing fixed on the material trough, a main shaft rotatably installed inside the housing, a track opened on the main shaft, a sliding sleeve slidably sleeved on the surface of the main shaft, and a sliding column fixed on the sliding sleeve. The sliding column is slidably connected in the track. Both ends of the reciprocating plate extend outside the material trough. One end of the reciprocating plate is fixed to the sliding sleeve. The sliding sleeve drives the reciprocating plate to slide, so that the channel gradually switches from corresponding to the first material port to corresponding to the second material port.

[0006] Furthermore, the track includes a spiral groove and an inclined groove, with the beginning and end of the spiral groove connected through the inclined groove.

[0007] Furthermore, a baffle is fixed inside the box, and sliding rods are symmetrically fixed on the baffle. The other end of the sliding rods movably passes through a sliding sleeve and is fixed inside the box. A spring is provided on the sliding rod, and the two ends of the springs are fixed to the baffle and the sliding sleeve, respectively.

[0008] Furthermore, a shaft is fixed on the main shaft, the shaft extends out of the housing and is fixed with a first gear, a residual gear meshes with one side of the first gear, the residual gear is rotatably connected to the housing through a central shaft, a motor is installed on the housing, and the output end of the motor is fixed to the central shaft.

[0009] Furthermore, the housing is provided with a cover plate, the cover plate has a slot for the reciprocating plate to slide, and the housing has a notch for the reciprocating plate to slide.

[0010] Furthermore, a material guiding mechanism is provided in the material trough. The material guiding mechanism includes multiple sets of scrapers. The scrapers are rotatably connected in the material trough through a rotating shaft. A second gear is fixed on the rotating shaft. Multiple sets of connecting plates are fixed on the side of the reciprocating plate away from the cross frame plate. The connecting plates are located between two adjacent sets of channels. Two sets of racks are symmetrically fixed on each set of connecting plates. The racks mesh with the corresponding second gears.

[0011] Furthermore, the scraper is provided with an auxiliary groove, and the second gear is located in the auxiliary groove.

[0012] Furthermore, multiple sets of adjustment mechanisms are provided on the side of the cross frame plate away from the reciprocating plate. The adjustment mechanisms are located at the first and second material inlets, respectively. Each set of adjustment mechanisms includes a top plate and a side plate rotatably mounted on the cross frame plate. The side plates are symmetrically distributed on both sides below the top plate. The top plate and the side plates are arranged in a U-shape. An elastic membrane is provided between the inner sides of the top plate and the side plates.

[0013] Furthermore, a connecting shaft is fixed to the side of the top plate and side plate away from the elastic membrane. Multiple sets of connecting blocks corresponding to the connecting shaft are fixed to the cross plate. The connecting shaft is rotatably connected to the corresponding connecting block. A torsion spring is provided on the connecting shaft. A cavity is opened in the connecting block. The two ends of the torsion spring are fixed to the corresponding connecting shaft and the cavity, respectively.

[0014] Furthermore, the frame is also equipped with an unwinding roller, a guide roller, and a scraper mechanism for smoothing the coating on the material.

[0015] The beneficial effects of this invention are: By setting up a feeding mechanism and a circulation mechanism, the reciprocating plate is continuously driven to slide back and forth in the trough to switch channels. This not only keeps the high-viscosity coating in the trough in a dynamic flow, effectively preventing it from solidifying or agglomerating due to poor flowability, but also guides the coating in the accumulated area to the thin area through the movement of the reciprocating plate, improving the uniformity of coating distribution. At the same time, the change in the coating flow path allows the anilox roller to obtain a stable supply at each point along the axis, which to some extent solves the problem of uneven mesh adsorption and significantly reduces the probability of local over-thickness or under-thinness of the coating on the tarpaulin base fabric.

[0016] By setting up a material guiding mechanism, the scraper can be driven to rotate in both directions by the sliding of the reciprocating plate. This can actively push the high-viscosity coating in the trough in a directional manner, effectively overcoming the viscous resistance of the coating and pushing the coating to the first or second feed port, thus further avoiding the accumulation of high-viscosity coating.

[0017] By setting up an adjustment mechanism, the interaction between the top plate, side plate and elastic membrane can be used to achieve dynamic flow regulation when the coating passes through the first or second feed port. When the local flow is too large, the elastic membrane can generate tensile deformation, which can effectively disperse the excessive local pressure and further reduce the problem of uneven coating adsorption by the anilox roller caused by flow fluctuation.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-2 The present invention provides a multifunctional covering mesh coating composite equipment, including a frame 1, an anilox roller 2 disposed on the frame 1, a back roller 3 slidably disposed above the anilox roller 2, a material trough 4 movably disposed below the anilox roller 2, and a lifting mechanism 5 disposed on the frame 1. The lifting mechanism 5 is used to control the up and down movement of the material trough 4. The frame 1 is also provided with an unwinding roller 10, a guide roller 11, and a scraper mechanism 12 for smoothing the coating on the material.

[0022] Reference Figures 3-5 It also includes a feeding mechanism 6 installed in the trough 4. Specifically, the feeding mechanism 6 includes a horizontal frame plate 61 fixed in the trough 4 and multiple sets of first feed ports 62 and second feed ports 63 equidistantly opened on the horizontal frame plate 61. The first feed ports 62 and second feed ports 63 are arranged alternately and at intervals, and the first feed ports 62 and second feed ports 63 are the same size. A reciprocating plate 64 is slidably connected in the trough 4. The reciprocating plate 64 is in slidable contact with the horizontal frame plate 61. The reciprocating plate 64 has channels 65 that correspond one-to-one with the first feed ports 62. The material is fed through the multiple sets of first feed ports 62 and second feed ports 63 arranged alternately on the horizontal frame plate 61. The second feed port 63, in conjunction with the back-and-forth sliding of the reciprocating plate 64, enables the switching and docking of the channel 65, which can create a dynamic diversion effect for high-viscosity coatings. When the channel 65 docks with the first feed port 62, the coating flows through the first feed port 62 to the contact area of ​​the anilox roller 2. As the reciprocating plate 64 slides, the channel 65 switches to docking with the second feed port 63, and the flow direction of the coating changes to the adjacent interval area. By changing the flow path, the anilox roller 2 can receive a stable supply of coatings at all points along the axial direction, avoiding the problem of uneven mesh adsorption, and thus reducing the probability of local over-thickness or under-thickness of the coating on the tarpaulin base cloth.

[0023] Reference Figures 6-7 The material trough 4 is equipped with a circulation mechanism 7. Specifically, the circulation mechanism 7 includes a housing 71 fixed on the material trough 4, a main shaft 72 rotatably disposed in the housing 71, a track 73 opened on the main shaft 72, a sliding sleeve 74 slidably sleeved on the surface of the main shaft 72, and a sliding column 75 fixed on the sliding sleeve 74. The sliding column 75 is slidably connected in the track 73. Both ends of the reciprocating plate 64 extend outside the material trough 4. Both sides of the material trough 4 are provided with fitting ports for the reciprocating plate 64 to slide. One end of the reciprocating plate 64 is fixed to the sliding sleeve 74. When the main shaft 72 rotates, it drives the track 73 to rotate synchronously. The sliding of the sliding column 75 in the track 73 causes the sliding sleeve 74 to reciprocate linearly along the axial direction of the main shaft 72, thereby driving the reciprocating plate 64 to slide back and forth in the material trough 4.

[0024] Specifically, refer to Figures 8-9The track 73 includes a spiral groove 731 and an inclined groove 732. The beginning and end of the spiral groove 731 are connected through the inclined groove 732. When the main shaft 72 rotates, the sliding column 75 enters from the beginning of the spiral groove 731 and gradually moves towards the end along the spiral trajectory of the spiral groove 731. During this process, the sliding sleeve 74 drives the reciprocating plate 64 to slide, so that the channel 65 gradually switches from corresponding to the first feed port 62 to corresponding to the second feed port 63. That is, when the sliding column 75 is at the beginning of the spiral groove 731, the channel 65 opened on the reciprocating plate 64 corresponds to the first feed port 62, and when the sliding column 75 is at the end of the spiral groove 731, the channel 65 opened on the reciprocating plate 64 corresponds to the second feed port 63.

[0025] It should be noted that, referring to Figure 7 A baffle 76 is fixed inside the housing 71. One end of the main shaft 72 passes through the baffle 76 and is rotatably connected to the housing 71 through a bearing. A slide rod 77 is symmetrically fixed on the baffle 76. The other end of the slide rod 77 movably passes through the sliding sleeve 74 and is fixed inside the housing 71. A spring 78 is provided on the slide rod 77. The two ends of the spring 78 are fixed to the baffle 76 and the sliding sleeve 74 respectively. When the slide rod 75 reaches the end of the spiral groove 731, it can retract to the beginning of the spiral groove 731 through the inclined groove 732 under the elastic action of the spring 78.

[0026] The main shaft 72 has a fixed shaft 721. One end of the shaft 721, facing away from the main shaft 72, is rotatably connected inside the housing 71. The other end of the shaft 721 extends outside the housing 71 and is fixed with a first gear 722. A residual gear 723 meshes with one side of the first gear 722. The residual gear 723 is rotatably connected to the housing 71 via a central shaft 724. A motor 725 is mounted on the housing 71. The output end of the motor 725 is fixed to the central shaft 724. When the toothed part of the residual gear 723 drives the first gear 722 to rotate, the main shaft 721 rotates. As shaft 72 rotates, slide column 75 slides along the first end of spiral groove 731 to the end of spiral groove 731. During this process, reciprocating plate 64 slides, causing channel 65 to switch from corresponding to the first feed port 62 to corresponding to the second feed port 63. When the toothless part of residual gear 723 disengages from the first gear 722, main shaft 72 stops rotating. At this time, under the elastic force of spring 78, slide column 75 retracts along inclined groove 732 to the first end of spiral groove 731, reciprocating plate 64 resets synchronously, and channel 65 re-corresponds to the first feed port 62, completing one reciprocating cycle.

[0027] Furthermore, a cover plate 79 is provided on the housing 71, and a slot 791 is provided on the cover plate 79 for the reciprocating plate 64 to slide. A notch 711 is provided on the housing 71 for the reciprocating plate 64 to slide. The cover plate 79 and the housing 71 form a closed space, which serves to protect the housing 71. The slot 791 on the cover plate 79 and the notch 711 on the housing 71 correspond to each other, providing a guiding function for the reciprocating plate 64.

[0028] Furthermore, refer to Figures 10-11 The material trough 4 is equipped with a guiding mechanism 8. Specifically, the guiding mechanism 8 includes multiple sets of scrapers 81, which are equidistantly distributed in the material trough 4 and located in front of the channel 65. The scrapers 81 are rotatably connected to the material trough 4 via a rotating shaft 82. A second gear 83 is fixed on the rotating shaft 82. Multiple sets of connecting plates 84 are fixed on the side of the reciprocating plate 64 away from the cross frame plate 61. The number of connecting plates 84 is the same as that of the scrapers 81. The connecting plates 84 are located between two adjacent sets of channels 65. Each set of connecting plates 84 is symmetrically fixed with two sets of racks 85. The racks 85 mesh with the corresponding second gears 83. When the reciprocating plate 64 moves with the main... When the shaft 72 rotates and slides, it drives the connecting plate 84 to move synchronously. The two sets of racks 85 on the connecting plate 84 alternately mesh with the corresponding second gear 83. When one set of racks 85 meshes with the second gear 83, it drives the rotating shaft 82 to rotate, causing the scraper 81 to rotate towards the first material port 62 or the second material port 63. At this time, the scraper 81 pushes the paint in the material trough 4 towards the corresponding material port. When the reciprocating plate 64 slides in the opposite direction, the other set of racks 85 meshes with the second gear 83, and the scraper 81 rotates in the opposite direction to continue pushing the paint towards the other corresponding material port.

[0029] The scraper 81 has an auxiliary groove 811, and the second gear 83 is located in the auxiliary groove 811.

[0030] Furthermore, refer to Figures 13-14 Multiple sets of adjustment mechanisms 9 are provided on the side of the cross plate 61 away from the reciprocating plate 64. Specifically, the adjustment mechanisms 9 are located at the first feed port 62 and the second feed port 63. Each set of adjustment mechanisms 9 includes a top plate 91 and a side plate 92 rotatably mounted on the cross plate 61. The side plates 92 are symmetrically distributed on both sides below the top plate 91. The top plate 91 and the side plates 92 are arranged in a U-shape. An elastic membrane 93 is provided between the inner sides of the top plate 91 and the side plates 92. When the coating passes through, if the local flow rate is too large, the pressure of the coating on the elastic membrane 93 increases, which will push the top plate 91 and the side plates 92 on both sides to rotate outward. At this time, the internal space of the U-shaped structure expands, and the elastic membrane 93 stretches accordingly. Through the deformation of the elastic membrane 93, the local excessive pressure can be effectively dispersed. By automatically adjusting the flow rate of the coating through the feed port, the problem of uneven coating adsorption by the anilox roller 2 caused by flow fluctuation can be further reduced.

[0031] The top plate 91 and the side plate 92 are each fixed with a connecting shaft 94 on the side away from the elastic membrane 93. The cross plate 61 is fixed with multiple sets of connecting blocks 95 corresponding to the connecting shaft 94. The connecting shaft 94 is rotatably connected to the corresponding connecting block 95. A torsion spring 96 is provided on the connecting shaft 94. A cavity 97 is opened in the connecting block 95. The two ends of the torsion spring 96 are fixed to the corresponding connecting shaft 94 and the cavity 97, respectively. When the elastic membrane 93 is pushed outward by the pressure of the coating, the connecting shaft 94 will rotate synchronously in the connecting block 95. At this time, the torsion spring 96 on the connecting shaft 94 is twisted and stored. When the coating flow decreases, the elastic restoring force of the torsion spring 96 will drive the connecting shaft 94 to rotate in the opposite direction, thereby restoring the top plate 91 and the side plate 92 to their original positions.

[0032] This invention also provides a working principle for a multifunctional covering mesh coating composite device: First, the covering mesh base fabric is released by the unwinding roller 10. The base fabric is guided by the guide roller 11 to the space between the anilox roller 2 and the back roller 3. The lifting mechanism 5 controls the material trough 4 to rise, so that the lower part of the anilox roller 2 is immersed in the coating in the material trough 4. After the motor 725 is started, its output end drives the central shaft 724 and the residual gear 723 to rotate. When the toothed part of the residual gear 723 meshes with the first gear 722, the shaft 721 drives the main shaft 72 to rotate, and the track 73 rotates synchronously. The sliding column 75 slides from the first end of the spiral groove 731 to the end of the spiral groove 731, so that the sliding sleeve 74 drives the reciprocating plate 64 to slide in the material trough 4. At this time, the reciprocating plate 64 slides in the material trough 4. The channel 65 on plate 64 gradually switches from corresponding to the first feed port 62 to corresponding to the second feed port 63. The paint flows to the contact area of ​​the anilox roller 2 through the switched feed port. When the toothless part of the residual gear 723 disengages from the first gear 722, the main shaft 72 stops rotating. Under the action of the spring 78, the slide column 75 retracts along the inclined groove 732 to the beginning of the spiral groove 731. The reciprocating plate 64 is reset, and the channel 65 re-corresponds to the first feed port 62, completing one cycle. At the same time, the reciprocating plate 64 drives the connecting plate 84 to move, so that the rack 85 and the second gear 83 alternately mesh, driving the scraper 81 to rotate forward and backward, pushing the paint in the trough 4 to the first feed port 62 or the second feed port 63.

[0033] When the paint passes through the first inlet 62 or the second inlet 63, if the local flow rate is too high, it will push the elastic membrane 93 of the regulating mechanism 9 to stretch, and the connecting shaft 94 of the top plate 91 and the side plate 92 will rotate outward around the center. At this time, the torsion spring 96 stores force, the internal space of the U-shaped structure expands, and the local excessive pressure is dispersed. When the paint flow rate decreases, the elastic restoring force of the torsion spring 96 drives the connecting shaft 94 to rotate in the opposite direction, thereby causing the top plate 91 and the side plate 92 to return to their original positions.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
