Description

Technical Field

[0001] This invention relates to the field of PVC processing technology, and more specifically, to a transparent PVC decorative film processing system. Background Technology

[0002] PVC film, whose main component is polyvinyl chloride, has other components added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is paint, the middle layer is mainly polyvinyl chloride, and the bottom layer is a backing adhesive. Essentially a vacuum-formed film, it is used for surface packaging of various panels, hence it is also called decorative film or adhesive film, and is applied in many industries such as building materials, packaging, and pharmaceuticals.

[0003] To enhance the aesthetics of decorative films, heat-printed patterns are often applied to the film surface. To ensure stable pattern formation and easy winding, the film is cooled after heat printing. Cooling methods typically include air cooling and water cooling. Water cooling is the preferred option due to its smaller space requirement and faster cooling efficiency. However, traditional water cooling requires drying afterward. The water-cooled decorative film contains a large amount of moisture, increasing the difficulty of subsequent drying and reducing the efficiency of decorative film processing. Summary of the Invention

After a pair of water-absorbing components have absorbed water for a period of time, they are controlled to rotate and detach from the decorative film. The sliding component is controlled to move and squeeze out the water from the water-absorbing sponge sleeve.

[0014] The advantages of this invention are: The decorative film of this invention is cooled by water bath through a water immersion station, which improves the cooling efficiency of the decorative film. After being cooled by water bath, the decorative film passes through two pressure plates. Under the action of the corresponding arc spring, the two pressure plates press the decorative film tightly, squeezing out most of the water on the decorative film, realizing the initial dehydration of the decorative film, reducing the difficulty of subsequent water absorption and air drying, and improving the processing efficiency. In this invention, the decorative film, after initial dehydration, enters the water absorption station. Passing through the water absorption station, the water on the decorative film is absorbed by the water-absorbing sponge sleeve, further reducing the difficulty of subsequent air drying and further improving processing efficiency. Before the water-absorbing decorative film enters the air-drying station for pre-drying, the air in the air collection chamber is directed to the decorative film through two sets of L-shaped air guide pipes for pre-drying, which further reduces the difficulty of subsequent air drying and further improves processing efficiency. This invention controls the rotation of a pair of absorbent components to detach from the decorative film after they have absorbed water for a period of time, controls the movement of the sliding component to squeeze out the water from the absorbent sponge sleeve, and controls the alternating use of the two pairs of absorbent components, thereby increasing the service life of the absorbent station and further improving processing efficiency. This invention controls the start of an exhaust fan to drive the corresponding reciprocating screw to rotate, thereby causing the sliding sleeve to slide back and forth along the guide rod. This allows water in the cold water tank to be periodically pumped into the storage tank through various sets of copper pipes. During the transportation process, the water in the copper pipes exchanges heat with the cold air drawn in by the exhaust fan, ensuring the normal circulation of cold water in the storage tank, improving the heat exchange effect with the decorative film, and further improving the processing efficiency.

Two rotating shafts 11 are arranged from top to bottom; an upper gear 12 and a lower gear 13 that mesh with each other are fixed on the two rotating shafts 11 respectively; an L-shaped plate 14 is slidably arranged between the inner walls of the mounting groove 10; a toothed plate 15 that meshes with the upper gear 12 is fixed on the bottom surface of the L-shaped plate 14; water-absorbing components 16 are rotatably arranged in both the upper guide groove 8 and the lower guide groove 9; sliding rods 17 are symmetrically fixed on the side of the water-absorbing station 5; a sliding component 18 that matches the water-absorbing component 16 is slidably arranged between the two sliding rods 17.

[0034] The working principle of this embodiment is as follows: After the transparent PVC decorative film is heat-printed, it is driven by an external transmission roller to pass through the water immersion station 4, the water absorption station 5, and the air drying station 6 in sequence, which reduces the difficulty of air drying and improves the processing efficiency. After a pair of water-absorbing parts 16 absorb water for a period of time, they are controlled to rotate and detach from the decorative film. The sliding part 18 is controlled to move to squeeze out the water in the water-absorbing parts 16. The alternating use of the two pairs of water-absorbing parts 16 is controlled, which increases the service life of the water absorption operation of the water absorption station 5 and further improves the processing efficiency. Example

[0035] Please see Figure 1-14This second embodiment is an improvement on the first embodiment as follows: Specifically, a surrounding plate 19 is provided between the surface of the cold water tank 2 and the vertical plate 3; a water storage tank 20 with an open top is provided on the side of the immersion station 4; an air collecting box 21 is fixed on the side of the drying station 6; two guide roller groups 22 are symmetrically rotated on the sides of the immersion station 4, the water absorption station 5, and the drying station 6; the guide roller group 22 includes an upper guide roller 23 and a lower guide roller 24 symmetrically arranged; the water storage tank 20 and the air collecting box 21 are opposite to each other. All sides are provided with clearance grooves 25 for passing through the decorative film; the side of the enclosure 19 is provided with an air outlet 26; two exhaust fans 27 are fixedly installed in the air outlet 26; the drive shaft of the exhaust fan 27 is fixedly connected to a reciprocating screw 28; each of the two reciprocating screws 28 is provided with a matching sliding sleeve 29; a U-shaped plate 31 is fixed to the side of the water suction station 5; a guide rod 72 is fixed to the side of the U-shaped plate 31; a sliding plate 30 that slides with the guide rod 72 is fixed between the two sliding sleeves 29; the side of the U-shaped plate 31 is located at Piston cylinders 32 are symmetrically fixed on both sides of the guide rod 72; ear plates 33 are fixed on both sliding sleeves 29; piston rods 34 are fixed on the sides of the ear plates 33; pistons 35 that slide and engage with the corresponding piston cylinders 32 are fixed to the ends of the piston rods 34; drain pipes 36 penetrating the cold water tank 2 are connected to the ends of both piston cylinders 32; water suction pipes 37 are connected to the periphery of both piston cylinders 32 near their ends; one-way valves are installed on both the drain pipes 36 and the water suction pipes 37; a threaded pipe is installed through the bottom surface of the water storage tank 20. 38; a threaded pipe 38 is threaded to a conveying component 39; the conveying component 39 includes a connecting pipe 40 threaded to the threaded pipe 38; a water outlet pipe 41 is fixed to the end of the connecting pipe 40; a one-way valve is provided on the water outlet pipe 41; a connecting box 42 is provided below the connecting pipe 40 and is coaxially arranged with it; several copper pipes 43 are evenly connected between the connecting box 42 and the connecting pipe 40; two branch pipes 44 are symmetrically connected to the periphery of the connecting box 42; the two branch pipes 44 are respectively connected to two drain pipes 36 through flexible hoses.

[0036] The working principle of this embodiment 2: The PVC decorative film is driven through a set of guide rollers 22 at the immersion station 4 and enters the water storage tank 20 filled with cold water through the clearance groove 25. After exiting the water storage tank 20, it enters the space between the two pressure plates 47 through another set of guide rollers 22. Then, it passes through a set of guide rollers 22 at the water absorption station 5 and the water absorption component 16 in sequence, and enters a set of guide rollers 22 at the air drying station 6 to enter the air collection box 21, and then exits from the air collection box 21.

[0037] The reciprocating screw 28 is a type of three-dimensional cam pair, which consists of two threaded grooves with the same pitch but opposite directions of rotation, connected at both ends by transition curves. The sliding sleeve 29 is equipped with a slider that matches the helical groove. The rotation of the reciprocating screw 28 causes the side of the helical groove to push the slider placed in the helical groove to perform axial reciprocating motion.

[0038] By controlling the activation of two exhaust fans 27, the corresponding reciprocating screws 28 are rotated, thereby causing the corresponding sliding sleeves 29 to slide back and forth along the guide rods 72. This causes the corresponding pistons 35 to slide back and forth along the corresponding piston cylinders 32. The end of the water suction pipe 37 is connected to a water delivery hose, which is placed in the cold water tank 2. By setting a one-way valve on the water suction pipe 37, water in the cold water tank 2 can only enter the piston cylinder 32 sequentially through the corresponding water delivery hose and the water suction pipe 37. By setting a one-way valve on the drain pipe 36, water in the piston cylinder 32 can only enter the water storage tank 20 sequentially through the drain pipe 36, the hose, several copper pipes 43, and the outlet pipe 41. The pistons 35 slide back and forth along the corresponding piston cylinders 32, periodically pumping cold water from the cold water tank 2 into the water storage tank 20, thus achieving a cold water circulation supply to the water storage tank 20 and improving the cooling effect of the water storage tank 20 on the PVC decorative film.

[0039] The water in the cold water tank 2 is diverted through several copper pipes 43 and exchanges heat with the cold air drawn in by the exhaust fan 27, which improves the cooling effect of the water entering the water storage tank 20. Example

[0040] Please see Figure 1-14 This third embodiment is an improvement on the second embodiment as follows: Specifically, a water collection box 45 is fixed to the side of the immersion station 4; a water outlet groove 46 is provided between the water collection box 45 and the inner wall of the water storage tank 20; a pressure plate 47 is symmetrically rotated between the upper and lower guide roller groups 22; an arc spring 48 is fixedly connected between the pressure plate 47 and the vertical plate 3; a return spring 49 is fixed between the two L-shaped plates 14 and the vertical plate 3; a first armature post 50 and a second armature post 51 are respectively fixed to the sides of the two L-shaped plates 14; a first electromagnetic coil 52 and a second electromagnetic coil 53 are symmetrically arranged on the sides of the vertical plate 3; the sliding member 18 includes a fixed plate 54; sliding holes 55 that slide with the sliding rod 17 are symmetrically opened on the sides of the fixed plate 54; an electromagnetic chuck 56 is installed on the sides of the vertical plate 3; the two opposite sides of the fixed plate 54 are symmetrically arranged. An X-shaped push plate 57 is fixed; an iron block 58 is fixed to the side of a fixed plate 54; a connecting spring 59 sleeved on a slide rod 17 is symmetrically arranged between the fixed plate 54 and the vertical plate 3; a connecting shaft 60 is rotatably arranged between the inner walls of the upper guide groove 8 and the lower guide groove 9; the connecting shaft 60 is coaxially fixedly connected to the corresponding rotating shaft 11; the water-absorbing component 16 includes a ball head 61 fixed on the connecting shaft 60; a first baffle 62 is fixed on the ball head 61; a connecting rod 63 is fixed to the side of the first baffle 62; a second baffle 64 is fixed to the end of the connecting rod 63; a slip ring 65 is slidably arranged on the connecting rod 63; a water-absorbing sponge sleeve 66 sleeved on the connecting rod 63 is fixed between the second baffle 64 and the slip ring 65; and an installation spring 67 sleeved on the connecting rod 63 is connected between the first baffle 62 and the slip ring 65.

[0041] The working principle of this embodiment 3: After being cooled by the water bath at the water-cooling station 4, the PVC decorative film passes through the two pressure plates 47. Under the elastic force of the corresponding arc springs 48, the two pressure plates 47 press the PVC decorative film, thereby squeezing out a large amount of water from the PVC, reducing the difficulty of subsequent air cooling, and thus improving processing efficiency.

[0042] The PVC decorative film passes through the two pressure plates 47 and enters the water absorption station 5. It then passes through two opposing water-absorbing sponge sleeves 66, which absorb the moisture from the PVC decorative film, further reducing the difficulty of subsequent air cooling and thus further improving processing efficiency.

[0043] Before the PVC decorative film that has absorbed water enters the air drying station 6 for air drying, the air in the air collection chamber 21 is directed to the PVC decorative film through two sets of L-shaped air guide pipes 70 for pre-drying, which further reduces the difficulty of subsequent air drying and further improves processing efficiency. Example

[0044] Please see Figure 1-14 This fourth embodiment is an improvement on the third embodiment. Specifically, the inner wall of the air collection box 21 is evenly provided with a number of installation ports 68; an exhaust fan 69 is installed in the installation port 68; L-shaped air guide pipes 70 are installed on the top and bottom of the air collection box 21; a controller 71 is installed on the surface of the U-shaped plate 31; the controller 71 is provided with a control module and a delay circuit module; the control module is electrically connected to the exhaust fan 69, the exhaust fan 27 and the electromagnetic chuck 56 respectively.

[0045] The working principle of this embodiment four is as follows: The delay circuit module includes a delay circuit and a power supply circuit that are connected in series with the first electromagnetic coil 52 and the second electromagnetic coil 53, respectively. Both delay circuits include a relay Kk, and a resistor R and a capacitor C are connected in parallel with the relay Kk. A relay K1 is connected in series in the power supply circuit. The controller 71 sends a control signal to control the on and off of the power supply circuit. The normally closed contact K1-1 of relay K1 is connected in series with the corresponding relay Kk in the delay circuit where the second electromagnetic coil 53 is located. The normally open contact K1-1 of relay K1 is connected in series with the corresponding relay Kk in the delay circuit where the first electromagnetic coil 52 is located. The normally open contact Kk1 of relay Kk is connected in series with the corresponding resistor R and capacitor C.

[0046] The RC delay circuit shown in the figure has a delay duration that can be adjusted by the value of R or C. When the power is first turned on, since the normally open contact KK1 in the delay circuit containing the first electromagnetic coil 52 is normally open, the delay circuit will not affect the energizing time. That is, the process of the water-absorbing part 16 rotating to contact the PVC decorative film after drainage is completed instantaneously. When the relay Kk is energized, its contact Kk1 closes, allowing the release of the relay Kk to proceed slowly. When the power circuit is turned on and off, the delay time is adjusted by the value of R. The charging and discharging action of C causes the relay Kk to release slowly, rather than being slowly engaged. This means that the process of the absorbent component 16 in contact with the PVC decorative film rotating to detach from the PVC decorative film requires a delayed action. This ensures that during the replacement of the two pairs of absorbent components 16, for a period of time after the pair of absorbent components 16 that has completed drainage rotates to contact the PVC decorative film, the other absorbent component 16 that is to be drained remains in contact with the PVC decorative film, delaying its detachment. This prevents both pairs of absorbent components 16 from detaching from the PVC decorative film during the switching process, which would affect the normal operation of the water absorption process.

[0047] Therefore, when the power circuit of relay K1 is disconnected and de-energized, the delay circuit of the second electromagnetic coil 53 remains energized, attracting the corresponding second armature column 51, which drives the corresponding L-shaped plate 14 to move along the corresponding mounting groove 10 towards the electromagnetic chuck 56, causing the corresponding upper gear 12 to rotate counterclockwise, thereby driving the corresponding lower gear 13 to rotate clockwise, so that the two sets of water-absorbing parts 16 arranged symmetrically rotate synchronously in opposite directions, so that the PVC decorative film is placed between the two water-absorbing sponge sleeves 66, and the water on the PVC is absorbed by the water-absorbing sponge sleeves 66; the controller 71 periodically controls the on and off of the power circuit, thereby controlling the alternating use of the two pairs of water-absorbing parts 16, improving the service life of the water-absorbing station 5, and further improving the processing efficiency.

[0048] After a pair of water-absorbing components 16 have absorbed water for a period of time, the power circuit of the control relay K1 is energized, the delay circuit of the second electromagnetic coil 53 is de-energized, and the delay circuit of the first electromagnetic coil 52 is energized, attracting the corresponding first armature column 51, which drives the corresponding L-shaped plate 14 to move away from the electromagnetic chuck 56 along the corresponding mounting groove 10, causing the corresponding upper gear 12 to rotate clockwise, thereby causing the corresponding lower gear 13 to rotate counterclockwise. The controller 71 controls its rotation to detach from the decorative film, and controls the electromagnetic chuck 56 to periodically gain and lose power. In conjunction with the connecting spring 59 and the mounting spring 67, the sliding component 18 moves back and forth, causing the X-shaped push plate 57 to push the slip ring 55 to squeeze out the water in the water-absorbing sponge sleeve 66. This controls the alternating use of the two pairs of water-absorbing components 16, increases the service life of the water-absorbing operation at the water-absorbing station, and further improves the processing efficiency.
