Description

Technical Field

[0001] This invention belongs to the technical field of bottle processing equipment, specifically relating to a thermal energy adsorption and recovery device for screen-printed solid waste gas from plastic bottles. Background Technology

[0002] Screen printing on bottles is a common printing process, mainly used to print patterns or text on the surface of bottles made of materials such as glass and plastic. The screen printing plate consists of a frame and a screen coated with photosensitive emulsion. The designed pattern is made into a film and placed on the emulsion-coated screen. Exposure cures the pattern, while the unexposed areas are washed away with water, creating a perforated pattern. Next, the ink is prepared, selecting the appropriate type based on the bottle material. For example, glass ink is often used for glass bottles, while plastic ink with strong adhesion is used for plastic bottles. The ink viscosity must be moderate; too thick or too thin will affect the printing effect. The printing process then begins. The bottle is fixed on the printing table, and the screen printing plate is aligned with the bottle. A squeegee spreads the ink across the screen, transferring it to the bottle surface through the perforated areas, completing the process.

[0003] Photocuring of plastic bottles refers to the process of surface treatment or molding of plastic bottles using light curing technology. Specific wavelengths of light trigger the polymerization reaction of the resin material, achieving rapid curing or enhanced performance. This process is efficient, energy-saving, and allows for precise control of the curing area.

[0004] In the UV curing process of plastic bottles, the bottle body is generally rolled by rollers and then processed in conjunction with a UV irradiator. However, the roller design is generally a fixed rolling structure, and the spacing between the rollers cannot be adjusted adaptively. Consequently, it cannot adapt to the connection of different bottle sizes. In addition, different volumes of liquid resin are required for plastic bottles of different sizes to ensure that the resin is evenly distributed on the bottle surface. However, the above requires a separate spraying mechanism to complete the resin spraying work, which reduces the practicality of the device. The poor structural integration performance is not conducive to improving the applicability of the device. Summary of the Invention

[0005] The purpose of this invention is to provide a heat energy adsorption and recovery device for the solidified waste gas from screen printing on plastic bottles, in order to solve the technical problem that the roller design is generally a rolling fixed structure, the spacing between the rollers cannot be adaptively adjusted, and therefore cannot be adaptively limited and connected to different bottle sizes, resulting in poor performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A thermal energy adsorption and recovery device for screen-printed waste gas from plastic bottles includes: A bottle screen printing mechanism includes a first motor fixed on a side plate. The output shaft of the first motor extends to a positioning column via a rotating gear. The outer wall of the rotating gear meshes with a gear plate fixed on a telescopic rod. One end of the telescopic rod is fixedly connected to a first slider. The first slider is connected to a sliding groove along the length of the support portion on the side plate, and both ends of the first slider are equipped with clamping plates that are limited and connected to the screen printing plate. The top of the first slider is detachably equipped with a scraper via a bending rod, and both sides of the scraper are provided with a first sprayer placed on the side plate. The light curing adjustment mechanism includes rollers placed at both ends of the side wall of the first housing. One end of each roller is fixed to a driver, and the other end is connected to a second slider. The rollers are connected by a conveyor belt.

[0007] Furthermore, one end of the conveyor belt is connected to a tensioning wheel placed on a cylinder. The outer edge of the tensioning wheel is provided with a rolling groove connected to the piston rod on the cylinder. The piston rod on the cylinder and the two sides of the second slider are connected by a first swing rod. An ultraviolet laser is provided above the roller and placed on the top of the inner wall of the first box.

[0008] Furthermore, both ends of the first swing rod are mounted on the piston rod and the second slider by means of rotational connection. The piston rod on the cylinder is fixedly mounted with a connecting rod. The connecting rod has a strip groove opened along the height direction of the partition on the inner wall of the first box. The connecting rod and the push plates on both sides are connected by the second swing rod. One end of the push plate is equipped with a connecting pipe extending into the interior of the second sprayer. The push plate and the outer wall of the second sprayer are connected by the first spring.

[0009] Furthermore, the connecting pipe is provided with a guide hole for connection to the second sprayer, and both ends of the second swing rod are mounted on the connecting rod and the push plate by means of rotational connection. A conveyor line is provided below the second sprayer and placed inside the first box.

[0010] Furthermore, the conveyor line is installed inside the first housing and extends along a preset direction to carry and transport the bottles.

[0011] Furthermore, it also includes a heat energy utilization mechanism, which includes a second housing. The air outlets of the second housing and the first housing are connected by a conduit fixed to the pump body. A one-way valve adapted to the conduit is installed on the conduit. A second motor is fixedly installed on the outer wall of the second housing. The output shaft of the second motor is connected to a movable shaft placed on the inner wall of the second housing. A first filter plate arranged in a ring is distributed on the movable shaft. An arc-shaped part is integrally formed on the outer wall of the first filter plate.

[0012] Furthermore, the upper and lower ends of the arc-shaped portion respectively move and abut against the first lifting plate and the second lifting plate. U-shaped plates are fixedly installed on both sides of the top end of the first lifting plate. The U-shaped plates move and abut against the pull rod. The top of the pull rod passes through the movable opening on the panel and extends to the sealing plate. One end of the sealing plate is rotatably connected to the top of the panel by a hinge. The top ends of the panel and the inner walls of the second box are connected by a second spring. The extension ends of the first lifting plate and the second box are connected by a third spring.

[0013] Furthermore, a sleeve is fixedly installed on the outer wall of the second lifting plate by equidistantly distributed crossbeams. The bottom of the sleeve is connected to a top rod extending into the interior of the second filter plate by a retaining ring, and the retaining ring is adapted to the size of the filter holes on the second filter plate. The second filter plate and the extended end of the inner wall of the second box are connected by a fourth spring.

[0014] Furthermore, an air inlet is provided below the second filter plate and on the outer wall of the second housing, and an air outlet is provided above the sealing plate and on the outer wall of the second housing.

[0015] Furthermore, electric push rods are fixedly connected to both sides of the support portion at the bottom of the first slider, and both ends of the clamping plate are fixed to the bracket by adjusting columns.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) In this invention, when the bottle is screen printed, the screen printing plate is first connected to the clamping plate and the bottle is fixed on the positioning post. Under the action of the first sprayer, the ink is sprayed onto the screen printing plate. The electric push rod is started and the screen printing plate and the scraper are transported together to the bottle on the positioning post. The first motor is started and the positioning post drives the bottle to rotate under the action of gear meshing transmission. The screen printing plate moves horizontally on the surface of the bottle. With the help of the scraper, the printing work on the surface of the bottle can be effectively realized. The telescopic rod on the gear plate can, on the one hand, drive the first slider to move freely up and down, so that the screen printing plate and the positioning post can be separated or attached, ensuring the stable operation of the printing work. On the other hand, it can keep the rotating gear and the gear plate in meshing state, so that the power can be transmitted to the clamping plate and the positioning post at the same time, avoiding the separation phenomenon during the movement of the structural parts and improving the safety of the device.

[0017] (2) In this invention, during the bottle curing process, the cylinder is first started and drives the piston rod to move up and down. Under the rotational connection of the first swing rod, the rollers on the second sliders at both ends are aligned or move in opposite directions. The spacing is adjusted to accommodate bottles of different sizes. Under the action of the driver, the conveyor belt can drive the rollers at both ends to rotate in the same direction, thus ensuring that the bottles on the rollers rotate normally. During the rotation, the ultraviolet light emitted by the ultraviolet laser can be used for the corresponding resin molding work. In order to ensure the normal transmission of the force of the conveyor belt, the spacing between the rollers becomes smaller during the downward push of the cylinder, and the conveyor belt becomes loose. At the same time, the tensioning wheel moves down synchronously to increase the transmission distance of the conveyor belt. During the upward push of the cylinder, the rollers... As the distance between the shafts increases, the conveyor belt becomes taut, and the tensioning wheel moves upward synchronously to reduce the transmission distance of the conveyor belt, thus ensuring the tension of the conveyor belt transmission. In addition, during the up-and-down movement of the cylinder, the connecting rod can move synchronously. Under the action of the second swing rod, in conjunction with the first spring connected to the push plate, the push plate can move horizontally. When the cylinder moves upward, it means that the distance between the rollers increases, and the size of the bottle also increases accordingly. Under the action of mechanical transmission, the push plate also moves inward toward the interior of the second sprayer, so that the guiding area of ​​the guide hole in the second sprayer also increases. By increasing the flow volume of the resin, the resin is evenly distributed on the bottle, thereby effectively and accurately controlling the curing effect and improving product quality.

[0018] (3) In this invention, during the light-curing process, the liquid resin becomes solid during the polymerization reaction, releasing volatile waste gas and heat. This waste gas enters the second chamber through the pump body. During the start-up of the second motor, the first filter plate can be driven to rotate. The rotation of the first filter plate can expand the contact area with the waste gas, and the particulate matter in the waste gas is absorbed by adsorption. In addition, during the rotation of the first filter plate, when it comes into contact with the first and second lifting plates at both ends, the first and second lifting plates move outward in opposite directions synchronously. When the U-shaped plate on the first lifting plate comes into contact with the pull rod, it can drive the sealing plate to rotate on the hinge and open the movable port to facilitate the discharge of waste gas. At the same time, during the downward movement of the second lifting plate, it can drive the sealing plate to rotate on the hinge and open the movable port to facilitate the discharge of waste gas. The moving push rod pushes downwards within the second filter plate, preventing particulate matter from clogging it. Similarly, as the second lifting plate moves upwards, the retaining ring closes the filter holes in the second filter plate. Simultaneously, the U-shaped plate on the first lifting plate, in contact with the pull rod, drives the sealing plate to rotate under the hinge, closing the movable opening and causing the panel to move downwards, forming a sealed area. Through compression, the internal temperature is increased, compensating for natural heat loss and ensuring the activity of the activated carbon on the first filter plate. This effectively improves the treatment effect of waste gas, adsorbing volatile organic compounds in the waste gas, preventing direct discharge, and further recycling the heat, which is beneficial to environmental protection.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference manual attached Figure 1 -Appendix Figure 12 As shown, the thermal energy adsorption and recovery device for the solidified waste gas from screen printing on plastic bottles includes: The bottle screen printing mechanism 1 includes a first motor 2 fixed on the side plate. The output shaft of the first motor 2 extends to the positioning column 4 through a rotating gear 3. The outer wall of the rotating gear 3 meshes with a gear plate 6 fixed on a telescopic rod 5. One end of the telescopic rod 5 is fixedly connected to a first slider 7. The first slider 7 is connected to a groove along the length of the support part on the side plate, and both ends of the first slider 7 are equipped with clamping plates 8 that are connected to the screen printing plate for positioning. A scraper 9 is detachably installed on the top of the first slider 7 through a bending rod. A first sprayer 10 is provided on both sides of the scraper 9 and placed on the side plate. The light curing adjustment mechanism 11 includes rollers 13 placed at both ends of the side wall of the first housing 12. One end of the roller 13 is fixed to the driver, and the other end is connected to the second slider 14. The rollers 13 are connected by a conveyor belt 15.

[0024] When screen printing is performed on the bottle, the screen printing plate is first fixed in the clamping plate 8, and the bottle is fixed on the positioning post 4. The positioning bolts can be used to clamp and fix the bottle. Under the action of the first sprayer 10, ink is sprayed onto the screen printing plate. The electric push rod 48 is started and the screen printing plate and the squeegee 9 are transported together to the bottle on the positioning post 4. The first motor 2 is started, and under the action of gear meshing, the positioning post 4 drives the bottle to rotate, and the screen printing plate moves horizontally on the surface of the bottle. With the help of the squeegee 9, the printing work on the surface of the bottle can be effectively achieved. The telescopic rod 5 on the gear plate 6 can, on the one hand, drive the first slider 7 to move freely up and down, so that the screen printing plate and the positioning post 4 can separate or fit together, ensuring the stability of the printing work. On the other hand, it can keep the rotating gear 3 and the gear plate 6 in a meshing state, so that the power can be transmitted to the clamping plate 8 and the positioning post 4 at the same time, avoiding separation of the structural components during the movement, and improving the safety of the device.

[0025] Specifically, the first slider 7 is essentially the movable end fixed to the telescopic rod 5. This ensures that the rotating gear 3 is always engaged with the gear plate 6 during the up-and-down movement of the clamping plate 8. Both sides of the support at the bottom of the first slider 7 are fixedly connected to electric push rods 48, and both ends of the clamping plate 8 are fixed to the bracket through adjusting columns. The bracket has a strip groove in the height direction that connects to the adjusting column, so that the adjusting column can perform normal horizontal telescopic movement and can also drive the clamping plate 8 to move up and down accordingly, thereby providing corresponding support force.

[0026] Specifically, one end of the conveyor belt 15 is connected to a tensioning wheel 17 placed on the cylinder 16. The outer edge of the tensioning wheel 17 is provided with a rolling groove connected to the piston rod on the cylinder 16. The piston rod on the cylinder 16 and the two sides of the second slider 14 are connected by a first swing rod 18. An ultraviolet laser 19 is provided above the roller 13 and placed on the top of the inner wall of the first housing 12.

[0027] During the bottle curing process, cylinder 16 is first activated, driving the piston rod to move up and down. Under the rotational connection of the first swing rod 18, the rollers 13 on the second sliders 14 at both ends move in the center or opposite directions, adjusting the spacing to accommodate bottles of different sizes. The driver, in conjunction with the conveyor belt 15, drives the rollers 13 at both ends to rotate in the same direction, ensuring the normal rotation of the bottles on the rollers 13. During rotation, ultraviolet light emitted by the ultraviolet laser 19 is used for resin molding. Furthermore, to ensure the normal transmission of force to the conveyor belt 15, as cylinder 16 pushes downwards, the spacing between the rollers 13 decreases, and the conveyor belt 15 becomes looser. Simultaneously, the tension wheel 17 descends synchronously to increase the transmission distance of the conveyor belt 15. As cylinder 16 pushes upwards, the spacing between the rollers 13... As the distance increases, the conveyor belt 15 becomes taut, and the tensioning wheel 17 moves upward synchronously to reduce the transmission distance of the conveyor belt 15, thus ensuring the tension of the conveyor belt 15. In addition, during the up-and-down movement of the cylinder 16, the connecting rod 49 can move synchronously. Under the action of the second swing rod 21, in conjunction with the first spring 24 connected to the push plate 20, the push plate 20 can move horizontally. When the cylinder 16 moves upward, it means that the distance between the rollers 13 increases, and the size of the bottle also increases accordingly. Under the action of mechanical transmission, the push plate 20 also moves accordingly towards the inside of the second sprayer 22. In this way, the guiding area of ​​the guide hole 25 in the second sprayer 22 also increases. By increasing the flow volume of the resin, the resin is evenly distributed on the bottle, thereby effectively and accurately controlling the curing effect and improving product quality.

[0028] Both ends of the first swing rod 18 are mounted on the piston rod and the second slider 14 by means of rotational connection. The piston rod on the cylinder 16 is fixedly mounted with a connecting rod 49. The connecting rod 49 has a strip groove along the height direction of the partition on the inner wall of the first housing 12. The connecting rod 49 and the push plates 20 on both sides are connected by the second swing rod 21. One end of the push plate 20 is equipped with a connecting pipe 23 extending into the interior of the second sprayer 22. The push plate 20 and the outer wall of the second sprayer 22 are connected by the first spring 24.

[0029] The connecting pipe 23 has a guide hole 25 connected to the second sprayer 22. Both ends of the second swing rod 21 are mounted on the connecting rod 49 and the push plate 20 by rotational connection. Below the second sprayer 22 is a conveyor line 26 placed inside the first box 12. The conveyor line 26 is installed inside the first box 12 and extends in a preset direction to carry and convey the bottle.

[0030] Specifically, it also includes a heat energy utilization mechanism 27, which includes a second housing 28. The second housing 28 and the air outlet of the first housing 12 are connected by a conduit fixed to the pump body. A one-way valve 29 adapted to it is installed on the conduit. A second motor 30 is fixedly installed on the outer wall of the second housing 28. The output shaft of the second motor 30 is connected to a movable shaft 31 placed on the inner wall of the second housing 28. A first filter plate 32 arranged in a ring is distributed on the movable shaft 31. An arc-shaped part 33 is integrally formed on the outer wall of the first filter plate 32.

[0031] The upper and lower ends of the arc-shaped part 33 respectively move and abut against the first lifting plate 34 and the second lifting plate 35. U-shaped plates 36 are fixedly installed on both sides of the top end of the first lifting plate 34. The U-shaped plates 36 move and abut against the pull rod 37. The top of the pull rod 37 passes through the movable opening 39 on the panel 38 and extends to the sealing plate 40. One end of the sealing plate 40 is rotatably connected to the top of the panel 38 by a hinge. The top ends of the panel 38 and the inner walls of the second housing 28 are connected by a second spring 41. The extension ends of the first lifting plate 34 and the second housing 28 are connected by a third spring 42.

[0032] The first filter plate 32 has an activated carbon layer. Since the light curing process generates corresponding waste gas, the main component of which is volatile organic compounds, which can be effectively absorbed by activated carbon adsorption. In order to ensure the effectiveness of the activated carbon, the temperature is controlled to maintain its activity, thereby ensuring high adsorption capacity. The second filter plate 45 can effectively block particulate matter in the waste gas. Moreover, the first lifting plate 34 and the second lifting plate 35, together with the transmission components, can not only maintain the internal temperature of the second box 28, but also prevent the filter holes on the second filter plate 45 from clogging, effectively improving the stability of the device.

[0033] A sleeve 43 is fixedly installed on the outer wall of the second lifting plate 35 via equally spaced crossbeams. A top rod 46 extending into the second filter plate 45 is connected to the bottom of the sleeve 43 via a retaining ring 44. The retaining ring 44 is adapted to the size of the filter holes on the second filter plate 45. The extension ends of the second filter plate 45 and the inner wall of the second housing 28 are connected by a fourth spring 47. An air inlet is located below the second filter plate 45 on the outer wall of the second housing 28, and an air outlet is located above the sealing plate 40 on the outer wall of the second housing 28.
