DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0019] Reference Figure 1-3 A dyeing and drying device for pHBV antibacterial decorative fabric includes a mounting frame 1. The mounting frame 1 is a cubic frame structure formed by welding multiple angle irons and can be connected to existing dyeing and drying equipment for continuous production. A conveying component 9, a winding and unwinding device, two sets of dyeing and drying components 4, a driving component 10 and two sets of tension control devices 6 are arranged on the mounting frame 1.

[0020] The conveying component 9 is a prior art, which is used to continuously convey the pHBV antibacterial decorative cloth forward. It mainly includes multiple conveying rollers 91 arranged parallel to each other. The multiple conveying rollers 91 transmit information to each other and can be driven by an external servo motor to rotate in the same direction. The pHBV antibacterial decorative cloth is placed on the conveying rollers 91 and is transmitted in one direction through the rotation of the conveying rollers 91.

[0021] The unwinding and rewinding device comprises an unwinding device 2 and a rewinding device 3, which work together to intermittently convey the hot stamping film forward, and the pHBV antibacterial decorative cloth and the hot stamping film have the same moving direction and speed.

[0022] The unwinding device 2 includes an unwinding roller 21 rotatably arranged on the mounting frame 1, and the hot stamping film is wound on the unwinding roller 21. The unwinding roller 21 is driven by an external servo motor. The hot stamping film is unwound by the rotation of the unwinding roller 21. The winding device 3 includes a winding roller 31 rotatably arranged on the mounting frame 1. The winding roller 31 is driven by an external servo motor. The movable end of the hot stamping film is fixed on the winding roller 31. The waste hot stamping film is wound and recycled by the rotation of the winding roller 31.

[0023] The two sets of dyeing and drying components 4 are located between the unwinding device 2 and the winding device 3. The pHBV antibacterial decorative cloth is transported to the bottom of the dyeing and drying components 4 by the conveying component 9. After the hot stamping film released by the unwinding device 2 is pressed and dyed with the pHBV antibacterial decorative cloth by the dyeing and drying components 4, the hot stamping film is peeled off from the dyeing and drying product as the hot stamping film is wound by the winding roller 31 and the dyeing and drying product is conveyed. The hot stamping film waste is wound by the winding roller 31. The two sets of dyeing and drying components 4 are arranged side by side in the order of feeding, and the two sets of dyeing and drying components 4 work alternately, so that the two sets of The hot stamping films consumed by the dyeing and drying components 4 are alternately spaced and connected end to end. The gaps during switching between the two groups of dyeing and drying components 4 are used to make up for the gap displacement between the pHBV antibacterial decorative fabrics when dyeing and drying one by one, so as to complete the skipping film feeding. This is beneficial to saving the use of hot stamping film and reducing the dyeing and drying costs. In addition, compared with the skipping operation of equipment with only a single hot stamping device, the two groups of dyeing and drying components 4 are beneficial to improving the time resources for skipping dyeing and baking, thereby reducing the impact of the acceleration generated by the skipping on the hot stamping film, reducing the risk of deformation and stretching of the hot stamping film, and improving the quality of hot stamping dyeing and baking.

[0024] Reference Figure 1-3 The dyeing and drying component 4 includes a dyeing and drying roller 41 and a supporting roller 42 which are arranged in corresponding positions. The dyeing and drying roller 41 can move up and down, and the supporting roller 42 can support the pHBV antibacterial decorative cloth. The pHBV antibacterial decorative cloth and the hot stamping film both pass through between the dyeing and drying roller 41 and the supporting roller 42. When the dyeing and drying roller 41 is in contact with the supporting roller 42, the dyeing and drying foil on the hot stamping film is transferred to the surface of the pHBV antibacterial decorative cloth.

[0025] The driving assembly 10 acts on the two sets of dyeing and drying rollers 41 at the same time, so that when one of the dyeing and drying rollers 41 moves toward the corresponding support roller 42, the other dyeing and drying roller 41 moves synchronously in the opposite direction, so as to realize the alternating operation of the two sets of dyeing and drying assemblies 4.

[0026] The dyeing and drying roller 41 and the supporting roller 42 pressurize the pHBV antibacterial decorative cloth and the hot stamping film. The hot stamping film is released by the unwinding device 2, passes through the dyeing and drying roller 41 and the supporting roller 42, and the hot stamping film and the pHBV antibacterial decorative cloth are squeezed by the dyeing and drying roller 41 and the supporting roller 42 to achieve dyeing and drying. After the dyeing and drying roller 41 moves upward and separates from the supporting roller 42, the pressure of the dyeing and drying roller 41 on the pHBV antibacterial decorative cloth disappears. At this time, the dyeing and drying roller 41 is in an idle state. During the process of switching the working state of the two dyeing and drying rollers 41, when both dyeing and drying rollers 41 are in an idle state, the servo motor stops driving the unwinding roller 21 and the winding roller 31. At this time, the conveying component 9 is still conveying the pHBV antibacterial decorative cloth. The distance moved by the pHBV antibacterial decorative cloth compensates for the blank area between two adjacent pHBV antibacterial decorative cloths, thereby reducing the use of the hot stamping film and saving the dyeing and drying cost.

[0027] Reference Figure 1-3 Two groups of vertical poles 5 are vertically arranged on the mounting frame 1, and the same mounting frame 43 is slidably arranged between the two vertical poles 5 of the same group. The dyeing and drying roller 41 is rotatably arranged in the mounting frame 43. The mounting frame 43 is convenient for the installation of the dyeing and drying roller 41 and serves the purpose of supporting the dyeing and drying roller 41. The vertical pole 5 and the mounting frame 43 cooperate with each other, which is conducive to ensuring the stable sliding of the mounting frame 43 in the longitudinal direction.

[0028] Reference Figure 3-4 The pHBV antibacterial decorative cloths a1, a2, a3, and a4 are arranged in sequence and dyed and dried one by one, and are transported by the conveying assembly 9. The distance between two adjacent pHBV antibacterial decorative cloths is d. By adjusting the distance d between the pHBV antibacterial decorative cloths, the pHBV antibacterial decorative cloths under the two dyeing and drying rollers 41 correspond to the odd positions or the even positions at the same time, that is, there are an odd number of pHBV antibacterial decorative cloths between the two dyeing and drying rollers 41, such as Figure 4 As shown, taking a pHBV antibacterial decorative cloth a3 as an example, the hot stamping film is divided into a plurality of zone units b1-b8 according to the length of the pHBV antibacterial decorative cloth. Since the hot stamping film is bent and inserted between the two dyeing and drying components 4, Figure 4 In the example, the hot stamping film is converted into a horizontal state in equal amounts for comparison. There are an odd number of zoning units between the two dyeing and drying rollers 41, such as Figure 4 As shown, three partitioning units b5, b6 and b7 are taken as an example.

[0029] The part of the hot stamping film before the dyeing and drying roller 41a is a complete part, and the hot stamping film between the dyeing and drying roller 41a and the dyeing and drying roller 41b forms a zebra pattern of intermittent consumption due to the dyeing and drying roller 41a, that is, the zoning units b5 and b7 have been consumed by the dyeing and drying roller 41a, and the hot stamping film after the dyeing and drying roller 41b has been consumed twice by the dyeing and drying roller 41a and the dyeing and drying roller 41b to be completely used up and form waste.

[0030] Reference Figure 4 , A, B and C are three states of the dyeing and baking process, in which in state A, the pHBV antibacterial decorative cloth a3 has been dyed and baked by the dyeing and baking roller 41a, and the pHBV antibacterial decorative cloth a4 comes under the dyeing and baking roller 41b and coincides with the position of the zoning unit b8. At this time, the dyeing and baking roller 41b moves downward to press the zoning unit b8 and the pHBV antibacterial decorative cloth a4 for dyeing and baking. The consumption rate of the hot stamping film is consistent with the conveying speed of the pHBV antibacterial decorative cloth. At the same time, the dyeing and baking roller 41a and the pHBV antibacterial decorative cloth a2 are in corresponding positions, and the dyeing and baking roller 41a is in an idle state. The pHBV antibacterial decorative cloth a2 passes directly from under the dyeing and baking roller 41a, waiting for the subsequent dyeing and baking roller 41b.

[0031] Reference Figure 4 As state A continues, it switches from state A to state B, the pHBV antibacterial decorative cloth a4' completes dyeing and drying, and the zoning unit b8' is completely consumed. At this time, the dyeing and drying roller 41b moves up and enters an idle state, and the dyeing and drying roller 41a moves down to prepare for work. When the two dyeing and drying rollers 41 switch working states, the dyeing and drying rollers 41a and 41b are not pressed together. At this time, the winding of the hot stamping film stops, and the lower edges of the dyeing and drying rollers 41a and 41b are both at the seam of the zoning unit, but the conveying component 9 still drives the pHBV antibacterial decorative cloth to move. In the process of the hot stamping film staying and the pHBV antibacterial decorative cloth moving, the moving distance of the pHBV antibacterial decorative cloth fills the gap d between the two adjacent pHBV antibacterial decorative cloths, so that the hot stamping films consumed by different dyeing and drying components 4 are connected at intervals, thereby avoiding the consumption of adjacent blanks by different dyeing and drying rollers 41.

[0032] Reference Figure 4 As state B continues, it switches from state B to state C, and the pHBV antibacterial decorative cloth a1" comes under the dyeing and drying roller 41a, and coincides with the position of the zoning unit b3". At this time, the dyeing and drying roller 41a moves down, and the zoning unit b3" and the pHBV antibacterial decorative cloth a1" are pressed and dyed. The consumption rate of the hot stamping film is consistent with the conveying speed of the pHBV antibacterial decorative cloth. At the same time, the dyeing and drying roller 41b and the pHBV antibacterial decorative cloth a3" are in corresponding positions, and the dyeing and drying roller 41b is in an idle state. The pHBV antibacterial decorative cloth a3" has completed dyeing and baking in the previous dyeing and baking task, and passes directly from under the dyeing and baking roller 41a to avoid repeated dyeing and baking. By analogy, the two dyeing and baking rollers 41 work alternately up and down to realize the dyeing and baking of the pHBV antibacterial decorative cloths at odd and even positions respectively, so that there is no waste of hot stamping film, which is beneficial to reducing the production cost of the enterprise.

[0033] A drive frame 7 for driving the reverse displacement of two dyeing and drying rollers 41 is horizontally slidably arranged on the top of the installation frame 1. A cylinder 8 is fixedly arranged on the installation frame 1, and the telescopic end of the cylinder 8 is fixedly connected to the drive frame 7. When the cylinder 8 expands and contracts, it drives the drive frame 7 to move horizontally, synchronously driving the two dyeing and drying rollers 41 to move in the reverse direction, thereby ensuring the coordination and synchronization of the movements of the two dyeing and drying rollers 41.

[0034] Refer to Figure 1 , a connecting card plate is fixedly arranged on the installation frame 1, a card slot is formed on the drive frame 7, and the connecting card plate is slidably connected to the card slot. Through the cooperation of the connecting card plate and the card slot, the stability of the horizontal displacement of the drive frame 7 on the installation frame 1 is ensured.

[0035] Refer to Figure 1 、 2 And 5, two groups of guiding grooves 71 are symmetrically formed on the drive frame 7, a guiding post 44 is fixedly arranged on the mounting bracket 43, the guiding post 44 is arranged corresponding to the guiding groove 71 one by one, and the guiding post 44 penetrates through the guiding groove 71 and abuts against the inner wall of the guiding groove 71. When the drive frame 7 moves horizontally, the horizontal relative position between the guiding groove 71 and the guiding post 44 changes. Since the guiding post 44 is fixed on the mounting bracket 43 and the mounting bracket 43 is longitudinally limited by the vertical rod 5, when the guiding groove 71 presses against the guiding post 44, it will drive the overall longitudinal displacement of the mounting bracket 43.

[0036] Refer to Figure 1 And 5 , the guiding groove 71 includes a high-position groove 711, a low-position groove 712, and an inclined groove 713 connecting the high-position groove 711 and the low-position groove 712. When the guiding post 44 moves in the high-position groove 711 and the low-position groove 712, its height remains unchanged. When the guiding post 44 moves in the inclined groove 713, it will press against the guiding post 44 to switch and transition between the low-position groove 712 and the high-position groove 711, so that the mounting bracket 43 drives the dyeing and drying roller 41 to change its longitudinal position. The starting-end spacing of the two groups of guiding grooves 71 is the same as the spacing between the two guiding posts 44, and the two guiding grooves 71 are symmetrically arranged. Therefore, the movement processes of the guiding posts 44 in the guiding grooves 71 are exactly opposite, realizing the synchronous reverse movement of the two dyeing and drying rollers 41. When the guiding post 44 is located in the low-position groove 712, the dyeing and drying roller 41 is in contact with the supporting roller 42. Therefore, when the guiding post 44 is located in the low-position groove 712, the corresponding dyeing and drying roller 41 enters the working state for dyeing and drying. When the guiding post 44 is located in the high-position groove 711, the corresponding dyeing and drying roller 41 enters the idle state.

[0037] Two sets of tension control devices 6 are respectively arranged on the two sets of dyeing and drying components 4, and are used to control the tension of the hot stamping film between the unwinding device 2 and the winding device 3. Since the unwinding and unwinding speeds of the unwinding device 2 and the winding device 3 are consistent, the length of the hot stamping film between the unwinding device 2 and the winding device 3 remains constant. When the two sets of dyeing and drying rollers 41 move up and down, the tension of the hot stamping film is bound to change. The tension control device 6 is helpful to control the tension of the hot stamping film within a reasonable range.

[0038] During the state switching of the two dyeing and drying rollers 41 , the tension control device 6 is used to ensure the constant tension of the hot stamping film, reduce the risk of wrinkles on the hot stamping film during the hot stamping process, and improve the hot stamping quality.

[0039] Reference Figure 1 , 5 and 6, the tension control device 6 includes two pressing plates 64, a plurality of fixed plates 62 and two tension control components 61, the two pressing plates 64 are fixedly connected to the side walls of the two mounting frames 43, and each pressing plate 64 is provided with two pressing grooves 63 in the horizontal direction, and the two pressing grooves 63 on the same pressing plate 64 are symmetrical about the axis of the dyeing and drying roller 41, and the projections of the pressing grooves 63 on different pressing plates 64 in the axis direction of the dyeing and drying roller 41 coincide; the fixed plate 62 is fixedly mounted on the side wall of the conveying component 9, and the positions of the fixed plate 62 and the pressing groove 63 correspond; the tension control component 61 includes two groups of parallel connecting plates 612, between which a guide roller 611 and a tension roller 613 are rotatably mounted, and the axes of the guide roller 611 and the tension roller 613 are parallel to the axis of the dyeing and drying roller 41.

[0040] The hot stamping film from the unwinding device 2 passes through the inner side of the tension roller 613 and the outer side of the guide roller 611 on one side in turn, and after passing the lower side of the dyeing and drying roller 41, it passes through the outer side of the guide roller 611 and the inner side of the tension roller 613 on the other side, and is wound onto another tension control device 6 in the same way, and is finally wound up by the winding device 3. The lower end of the connecting plate 612 is rotatably connected to the upper end of the fixed plate 62, and the upper end of the connecting plate 612 is slidably connected to the pressing groove 63. When the tension roller 613 rotates toward the dyeing and drying roller 41, the hot stamping film is tightened, otherwise it is relaxed.

[0041] Reference Figure 5-7When the pressing plate 64 drives the pressing groove 63 to move longitudinally, it drives the tension roller 613 to change its position. When the pressing plate 64 moves up, the tension roller 613 expands outward. When the pressing plate 64 moves downward, the tension roller 613 retracts inward. Therefore, when the two dyeing and drying rollers 41 move in opposite directions, the dyeing and drying roller 41 that moves downward for dyeing and drying causes the tension rollers 613 on both sides to contract and tighten the hot stamping film to facilitate dyeing and drying. In addition, the idle dyeing and drying roller 41 causes the tension rollers 613 on both sides to expand outward to compensate for the pulling force generated by the tightening of the hot stamping film, reduce the risk of tensile deformation of the hot stamping film, and improve the hot stamping quality. The upper end of the fixed plate 62 is higher than the upper end of the supporting roller 42. The dyeing and drying roller 41 is flush with the lower ends of the two tension rollers 613 in the initial position, so that the hot stamping film between the two tension rollers 613 is in a horizontal state. When the dyeing and drying roller 41 moves downward, the hot stamping film on the lower side of the dyeing and drying roller 41 moves downward to change the tension of the hot stamping film.

[0042] Reference Figure 6-7 When the lower edge of the guide roller 611 is higher than the upper edge of the support roller 42, when the dyeing and drying roller 41 embosses the hot stamping film, the hot stamping film is pressed downward by the dyeing and drying roller 41 to form a "V" shape, and the hot stamping film forms an angle with the conveying plane, avoiding the parallel occurrence of the stamping and peeling processes, which is beneficial to keeping the hot stamping film flat during the unwinding and dyeing and drying processes.

[0043] The following steps are involved: S1: Preparation before starting, pull the active end of the hot stamping film out from the unwinding device 2, pass it through two sets of dyeing and drying components 4 in sequence, and then fix it on the winding device 3 for winding, and control the unwinding and winding device 2 to operate only when the hot stamping film is attached to the pHBV antibacterial decorative cloth; S2: Dyeing and drying UV adhesive on the pHBV antibacterial decorative cloth and curing the UV adhesive, adjusting the discharge spacing of the pHBV antibacterial decorative cloth so that the spacing of the pHBV antibacterial decorative cloth at two odd positions is equal to the spacing of the two hot stamping rollers 41, conveying the pHBV antibacterial decorative cloth through the conveying component 9, and controlling the transmission speed of the conveying component 9 to be consistent with the moving speed of the hot stamping film; S3: Start the driving assembly 10, control the cylinder 8 to drive the driving frame 7 to move, so that one of the dyeing and drying rollers 41 is close to the supporting roller 42, the pHBV antibacterial decorative cloth and the hot stamping film are pressed together, and the dyeing and drying foil on the hot stamping film is transferred to the surface of the pHBV antibacterial decorative cloth, and the other dyeing and drying roller 41 is away from the supporting roller 42. The two dyeing and drying rollers 41 correspond to the odd-numbered positions or the even-numbered positions of the pHBV antibacterial decorative cloth at the same time. The driving frame 7 reciprocates to make the two dyeing and drying rollers 41 work alternately up and down, respectively. For the dyeing and drying of the pHBV antibacterial decorative cloth at odd and even positions, and in the time interval when the two dyeing and drying rollers 41 switch the working state, the pHBV antibacterial decorative cloth continues to move to make up for the gap displacement between two adjacent pHBV antibacterial decorative cloths, so that the hot stamping films consumed by different dyeing and drying components 4 are connected at intervals, thereby avoiding that different dyeing and drying rollers 41 consume part of the adjacent blanks, and as the dyeing and drying rollers 41 move downward, the hot stamping film is tightened under the action of the tension control device 6, and the hot stamping film and the pHBV antibacterial decorative cloth are compounded together by pressure; S4: With the movement of the conveying component 9 and the winding of the hot stamping film, the excess hot stamping film is peeled off from the pHBV antibacterial decorative cloth, and only the part coated with the UV adhesive is dyed and dried to obtain the required dyeing and drying.
