UV curing mechanism for PVC floor production

Abstract

This utility model relates to a UV curing mechanism for PVC flooring production, comprising a housing. A controller is located on the front of the housing, and two temperature sensors are located on both sides of the housing. The ends of each set of temperature sensors, close to each other, penetrate the housing and extend into its interior. Two reflectors are located inside the housing, and two sets of UV curing lamps are located on the sides of the reflectors close to each other, with two lamps in each set. Two electric push rods are located on the upper and lower surfaces of the housing. By setting up a linkage structure between the electric push rods and the reflectors, the height of the UV curing lamps can be precisely adjusted by the controller to achieve adaptive irradiation of PVC substrates of different thicknesses without the need for manual adjustment during machine shutdown, significantly improving production continuity. At the same time, the two sets of UV curing lamps, together with the reflectors, form a three-dimensional irradiation space. Combined with the temperature sensors, the temperature inside the housing is monitored in real time to avoid local overheating that could cause deformation of the substrate.

Description

Technical Field

[0001] This utility model belongs to the technical field of PVC flooring production equipment, specifically relating to a UV curing mechanism for PVC flooring production. Background Technology

[0002] The UV curing unit in PVC flooring production is a key piece of equipment that uses ultraviolet (UV) irradiation to rapidly cure coating materials. It is widely used in the coating process of wear-resistant and decorative layers on the floor surface. Its core function is to ensure that the coating completes the cross-linking reaction in a short time through the cooperation of efficient UV light source and precise mechanical transmission, forming a hard and wear-resistant cured film, thereby improving the physical properties and weather resistance of the floor. In the production of roll PVC flooring, the material is first unwound from the unwinding device, and then passes through the splicing platform and the fabric storage device for stable conveying. Then, UV glue or related coating materials are applied at the coating roller, and then it enters the oven equipped with a UV tube.

[0003] However, in the UV curing process of PVC flooring production, the UV irradiation height of existing equipment cannot be flexibly adjusted as needed, resulting in insufficient ease of use. Traditional curing mechanisms mostly adopt fixed or manually adjustable structures, which are difficult to accurately adapt to PVC substrates of different thicknesses. When switching specifications, it is necessary to stop the machine for debugging, and the adjustment accuracy depends on human experience, which can easily cause uneven curing or thermal deformation of the substrate, affecting the continuity and applicability of the production line. There is an urgent need for a more intelligent height adjustment solution to improve the flexibility of the equipment.

[0004] To address the aforementioned issues, this application proposes a UV curing mechanism for PVC flooring production. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Please see Figure 1-4 The present invention provides the following technical solution: a UV curing mechanism for PVC flooring production, comprising a box 1, a controller 3 on the front of the box 1, two temperature sensors 2 on both sides of the box 1, the ends of each set of temperature sensors 2 that are close to each other penetrating the box 1 and extending into the interior of the box 1, two reflectors 12 inside the box 1, two sets of UV curing lamps 14 on the sides of the two reflectors 12 that are close to each other, and two electric push rods 15 on the upper and lower surfaces of the box 1, the telescopic ends of each set of electric push rods 15 penetrating the box 1 and fixedly connected to the sides of the two reflectors 12 that are far from each other; In this embodiment, the UV curing lamp 14 uses a high-power lamp tube, which has the characteristics of low energy consumption, long life and stable irradiation intensity. Meanwhile, the controller 3 adopts a PLC programmable logic controller, which supports touch operation and parameter preset, and can accurately control the extension and retraction of the electric push rod 15 and the working power of the UV curing lamp 14. Furthermore, the reflector 12 is an arc-shaped structure made of mirror aluminum, which can efficiently reflect ultraviolet rays and focus them on the surface of the substrate, thereby improving light utilization while ensuring irradiation uniformity.

[0018] Specifically, two sets of support columns 6 are fixedly connected to the bottom surface of the housing 1. Each support column 6 has a support ring 7 fixedly connected to its bottom end. In this embodiment, the combination structure of the support column 6 and the support ring 7 provides stable support for the entire curing mechanism. The support ring 7 increases the contact area with the ground, effectively dispersing the weight of the equipment and preventing the overall displacement caused by vibration during equipment operation. At the same time, the height design of the support column 6 allows the bottom of the housing 1 to maintain a certain gap with the ground, which is convenient for ground cleaning and equipment ventilation and heat dissipation.

[0019] Specifically, a connecting plate 4 is fixedly connected to the right side of the controller 3. The right side of the connecting plate 4 is fixedly connected to the left side of the housing 1. In this embodiment, the controller 3 is securely installed on the side of the housing 1 by the connecting plate 4, which not only ensures a reliable connection between the controller 3 and the housing 1, but also creates an appropriate distance between the controller 3 and the housing 1 to prevent the heat from the housing 1 from being directly conducted to the controller 3 during operation. At the same time, it facilitates the operator to conveniently operate the controller 3 from the side of the equipment, thus optimizing the human-machine interaction position.

[0020] Specifically, each temperature sensor 2 has a fixing ring 5 fixedly connected to its outer surface. The side of each set of fixing rings 5 ​​that is close to each other is fixedly connected to the two sides of the housing 1. In this embodiment, the temperature sensor 2 is double-fixed by the fixing rings 5 ​​to ensure that its installation position through the housing 1 is accurate and stable, and to avoid the temperature sensor 2 from loosening or displacement due to equipment vibration. This ensures the accuracy of temperature monitoring inside the housing 1 and provides reliable data support for temperature control.

[0021] Specifically, a transparent panel 8 is snapped onto the left side of the housing 1, and a connecting frame 9 is fixedly connected to the outer surface of the transparent panel 8. The right side of the connecting frame 9 is fixedly connected to the left side of the housing 1. In this embodiment, the connecting frame 9 strengthens the connection between the transparent panel 8 and the housing 1, preventing the transparent panel 8 from falling off due to long-term use or external impact. At the same time, the transparent panel 8 is made of a high-transmittance and high-temperature resistant material, which makes it easy for operators to observe the curing status of the PVC substrate inside the housing 1 in real time. The production status can be grasped without opening the equipment, reducing temperature fluctuations caused by frequent door opening.

[0022] Specifically, the front and back of the housing 1 are hinged with opening and closing doors 11, and handles 10 are fixedly connected to the sides of the two opening and closing doors 11 that are far apart from each other. In this embodiment, the opening and closing of the housing 1 is realized by the opening and closing doors 11. When closed, it can reduce the entry of dust into the housing 1 and keep the inside clean. When opened, it is convenient to inspect and maintain the UV curing lamp 14, reflector 12 and other components inside the housing 1. The handles 10 provide a convenient force point for operating the opening and closing doors 11, which improves the convenience of equipment maintenance.

[0023] Specifically, each UV curing lamp 14 has two fixed brackets 13 fixedly connected to its outer surface. The side of each set of fixed brackets 13 that is far apart from each other is fixedly connected to the side of each of the two reflectors 12 that is close to each other. In this embodiment, the UV curing lamp 14 is firmly installed on the reflector 12 by the fixed brackets 13, ensuring that the UV curing lamp 14 will not shift its position due to vibration during operation. At the same time, the fixed brackets 13 are made of high temperature resistant insulating material, which not only ensures connection stability but also avoids potential circuit safety hazards, so that the light from the UV curing lamp 14 can be accurately focused and reflected by the reflector 12.

[0024] Specifically, each electric push rod 15 has a support frame 16 fixedly connected to its outer surface. The side of each set of support frames 16 that is close to each other is fixedly connected to the upper surface and the bottom surface of the housing 1, respectively. In this embodiment, the support frame 16 forms an auxiliary support for the electric push rod 15, which enhances the stability of the connection between the electric push rod 15 and the housing 1, prevents the electric push rod 15 from shaking or tilting during frequent extension and retraction adjustment, ensures that it can accurately drive the reflector 12 to adjust the height, and improves the operational stability and service life of the entire height adjustment system.

[0025] The working principle and usage process of this utility model are as follows: First, the PVC flooring to be cured is unrolled on the unwinding device and pulled by the conveying equipment, allowing the coated PVC flooring to be uniformly conveyed through the chamber 1. At this time, the operator, based on the flooring thickness and coating characteristics, presets the irradiation intensity and working time of the UV curing lamp 14 using the controller 3, and sets the extension parameters of the electric push rod 15, precisely adjusting the height of the reflector 12 and the UV curing lamp 14 to achieve the optimal irradiation distance between them and the PVC flooring surface. When the chamber 1 is working, the opening and closing door 11 remains open so that the PVC flooring can continuously enter and exit the chamber 1 to receive irradiation from the UV curing lamp 14. The controller 3 controls the electric push rod 15 to start, and its extension end drives the reflector 12 to smoothly rise and fall to the designated height. Then, the UV curing lamp 14 turns on, emitting high-intensity ultraviolet rays, which, in conjunction with the mirror... The aluminum reflector 12 forms a three-dimensional irradiation space, allowing the floor coating to cure quickly. During this process, the temperature sensor 2 monitors the internal temperature of the chamber 1 in real time. If an abnormality occurs, the controller 3 immediately adjusts the power of the UV curing lamp 14 or the height of the electric push rod 15 to ensure uniform curing and prevent substrate deformation. Operators can also observe the curing status at any time through the viewing panel 8. When maintenance or repair is required, the opening and closing door 11 can be opened by the handle 10 to facilitate the inspection, replacement, and maintenance of components such as the UV curing lamp 14 and reflector 12 inside the chamber 1. When the chamber 1 is not in use, the opening and closing door 11 is closed to prevent dust and debris from entering the chamber 1 and to isolate the equipment from the influence of the external environment, thus extending the service life of the equipment. Throughout the process, the support column 6 and support ring 7 ensure the stability of the equipment, and the support frame 16 enhances the stability of the electric push rod 15, ensuring reliable operation of the equipment.
