Description

Technical Field

[0001] This utility model relates to the field of UV curing machines, specifically a UV curing machine for chemical coatings. Background Technology

[0002] UV curing machines utilize ultraviolet light emitted from UV light sources to react chemically with photosensitizers in chemical coatings. This triggers photopolymerization and crosslinking reactions between unsaturated acrylate oligomers and active monomers in the coating, causing the coating to transform from a liquid to a solid state in a short time, forming a cured coating with specific properties.

[0003] In the curing process of chemical coatings, it is necessary to strictly control the ambient temperature to ensure the performance of the product. However, due to the small size and compact structure of existing chemical coating curing machines, high temperatures often occur inside the UV curing machine, causing damage to internal parts. When it is necessary to repair the UV curing machine, many parts need to be disassembled, which is quite inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, which often result in high temperatures inside UV curing machines due to their small size and compact structure, causing damage to internal parts and requiring the disassembly of many parts for maintenance, this invention proposes a UV curing machine for chemical coatings.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a UV curing machine for chemical coatings, including a barrel and a protective cover for covering the barrel. A visible panel is provided on the surface of the protective cover. A fixed machine housing is slidably connected in a downward-facing groove of the protective cover. An arc door is rotatably connected in the interlayer of the fixed machine housing. A support component is provided at the bottom of the fixed machine housing.

[0006] The support assembly includes a base, a first fixed seat fixedly connected to the surface of the base, a supporting diagonal brace rotatably connected to the side of the first fixed seat, a second fixed seat sleeved on the end of the supporting diagonal brace away from the first fixed seat, a support plate fixedly connected above the second fixed seat, a square groove formed on the support plate near the base, an extension block fixedly connected to the surface of the base, the support plate rotating outside the extension block, a first collar and a second collar fixedly connected to the bottom ends of the support plate and the extension block respectively, an L-shaped straight rod sliding inside the first collar and the second collar, a rotating rod fixedly connected to the top end of the L-shaped straight rod, a concave seat sliding on the bottom surface of the rotating rod, and the concave seat fixed above the support plate.

[0007] Preferably, a hydraulic rod is fixed to the top of the support plate, and a support ring is sleeved on the surface of the hydraulic rod. One end of the support ring is fixedly connected to the surface of the protective cover. The protective cover slides up and down on the outside of the fixed machine housing, and the bottom end of the protective cover is in contact with the top end of the base.

[0008] Preferably, the base is provided with an irradiation assembly, which includes a stepper motor. The output end of the stepper motor is fixedly connected to a rotating arm. A circular plate is fitted on the top of the rotating arm. An arc groove is formed on the surface of the circular plate. The arc groove on the surface of the circular plate drives the UV lamp at the top to rotate. The UV lamp rotates in a circumferential direction in the cavity of the fixed housing.

[0009] Preferably, a pull rod is fixedly connected to the center side of the UV lamp, and horizontal grooves are provided on the top and both sides of the pull rod.

[0010] Preferably, a fixing pin is provided at the top of the circular plate, the fixing pin passes through the horizontal groove on the upper side of the fixing pin and is fixedly connected to the top of the circular plate, and a locking pin is slidably provided on the side of the fixing pin, the locking pin passes through the pull rod and is threadedly connected to the fixing pin.

[0011] Preferably, the top of the base has a circular slot, the stepper motor is fixed inside the circular slot of the base, and the rotating arm rotates inside the circular slot of the base.

[0012] Preferably, a reflective pad is fixedly connected to the inner wall of the fixed housing, and a handle is fixedly connected to the outer side of the arc-shaped door.

[0013] The advantages of this utility model are:

[0014] This invention adds a protective cover to the outside of the fixing machine housing to cover the housing and prevent strong diffuse reflection when the UV lamp inside the housing irradiates the material cylinder. A support plate is added to the outside of the base to support the hydraulic rod. The bottom end of the hydraulic rod is threaded to the top end of the support plate, which facilitates the disassembly and maintenance of the protective cover and hydraulic rod. The support plate can be removed when not in use. By pulling the L-shaped straight rod out from inside the first and second rings, the limiting of the first and second rings is released, and the support plate and the side of the base are folded. Then, the UV lamp is placed in the arc groove inside the circular plate. The stepper motor drives the rotating arm to control the rotation of the UV lamp in the arc groove of the circular plate. By pulling the pull rod connected to the UV lamp, the tilt angle between the UV lamp and the material cylinder is changed, thereby changing the irradiation direction of the UV lamp. This solves the problem of low curing efficiency caused by only being able to irradiate a certain position. Attached Figure Description

[0023] 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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a UV curing machine for chemical coatings. (See also...) Figure 1 and Figure 6 A UV curing machine for chemical coatings includes a barrel 53 and a protective cover 1 for covering the barrel 53. A visible panel 52 is provided on the surface of the protective cover 1. A fixed machine housing 2 is slidably connected in a downward-facing groove of the protective cover 1. An arc door 22 is rotatably connected in the interlayer of the fixed machine housing 2. A support component 3 is provided at the bottom of the fixed machine housing 2.

[0026] The support assembly 3 includes a base 311, a first fixed seat 31 fixedly connected to the surface of the base 311, a supporting diagonal brace 32 rotatably connected to the side of the first fixed seat 31, a second fixed seat 33 sleeved on the end of the supporting diagonal brace 32 away from the first fixed seat 31, a support plate 34 fixedly connected above the second fixed seat 33, the supporting diagonal brace 32 supporting the support plate 34, a square groove being formed on the support plate 34 near the base 311, an extension block 35 fixedly connected to the surface of the base 311, the support plate 34 rotating outside the extension block 35, and a first collar 36 and a second collar 36 fixedly connected to the bottom ends of the support plate 34 and the extension block 35, respectively. 8. An L-shaped straight rod 37 slides inside the first ring 36 and the second ring 38. The L-shaped straight rod 37 is pulled out from the bottom of the first ring 36 and the second ring 38, releasing the restriction of the L-shaped straight rod 37 on the first ring 36 and the second ring 38. At this time, the extension block 35 and the support plate 34 can be movably connected. When the support plate 34 is not needed to support the hydraulic rod 5 during daily use, the support plate 34 can be shielded from the outside of the base 311 to reduce the space occupied. A rotating rod 39 is fixedly connected to the top of the L-shaped straight rod 37. A concave seat 310 slides on the bottom surface of the rotating rod 39. The concave seat 310 is fixed above the support plate 34.

[0027] Reference Figure 1 and Figure 6 A hydraulic rod 5 is fixed to the top of the support plate 34. The hydraulic rod 5 is used to control the protective cover 1 to move up and down on the outside of the fixed machine housing 2, so as to close and open the fixed machine housing 2. A support ring 51 is sleeved on the surface of the hydraulic rod 5. One end of the support ring 51 is fixedly connected to the surface of the protective cover 1. The protective cover 1 slides up and down on the outside of the fixed machine housing 2. The protective cover 1 is used to shield the fixed machine housing 2 to prevent the light generated by the UV lamp 43 from damaging the eyes of the workers during the processing. The bottom end of the protective cover 1 is attached to the top end of the base 311 to prevent light diffusion.

[0028] Reference Figure 4 and Figure 5The base 311 is equipped with an irradiation component 4, which includes a stepper motor 41. The output end of the stepper motor 41 is fixedly connected to a rotating arm 42. The other side of the rotating arm 42 drives the UV lamp 43 at the top to rotate on the arc groove 48 on the surface of the circular plate 49. The UV lamp 43 rotates in a circumferential direction in the cavity of the fixed housing 2. By making the UV lamp 43 move in a circumferential manner, the problem of the UV lamp 43 being unable to move and only being able to rotate at a certain position of the barrel 53, resulting in poor curing effect, is changed. The ultraviolet rays and photothermal emitted by the UV lamp 43 cure the barrel 53.

[0029] Reference Figure 4 and Figure 5 A pull rod 44 is fixedly connected to the center side of the UV lamp 43. Horizontal grooves 46 are provided on the top and both sides of the pull rod 44. By pulling the pull rod 44 to move in the direction of the fixing pin 45, the other end of the pull rod 44 will cause the UV lamp 43 to shift. After the shift, the direction of the UV lamp 43 will be changed, avoiding the traditional method of only irradiating the front of the material cylinder 53.

[0030] Reference Figure 4 and Figure 5 A fixing pin 45 is provided at the top of the circular plate 49. The fixing pin 45 passes through the horizontal groove 46 on the upper side of the fixing pin 45 and is fixedly connected to the top of the circular plate 49. A locking pin 47 slides on the side of the fixing pin 45. The locking pin 47 passes through the pull rod 44 and is threadedly connected to the fixing pin 45. After the angle of the UV lamp 43 is determined, the locking pin 47 is re-inserted from the horizontal groove 46 on the side of the fixing pin 45 and threadedly tightened to fix the fixing pin 45 to the pull rod 44.

[0031] Reference Figure 5 The base 311 has a circular slot at the top. The stepper motor 41 is fixed inside the circular slot of the base 311. The rotating arm 42 rotates inside the circular slot of the base 311. While arranging the internal space, it isolates the heat generated by the UV lamp 43 from directly baking the stepper motor 41, resulting in a higher temperature when the stepper motor 41 is working.

[0032] Reference Figure 3 and Figure 4 A reflective pad 21 is fixedly connected to the inner wall of the fixed housing 2 to concentrate the heat generated by the UV lamp 43 and prevent the heat from overflowing. A handle 23 is fixedly connected to the outer side of the arc door 22. By adding the handle 23, it is easy to slide the arc door 22 out of the arc groove 48 of the fixed housing 2.

[0033] Working principle:

[0034] First, the operator grasps the handle 23 on the outside of the arc-shaped door 22 and slides it towards the arc-shaped groove of the fixed machine housing 2, placing the material cylinder 53 on top of the base 311. Then, the hydraulic rod 5 is activated, and the sliding rod at the top of the hydraulic rod 5 drives the support ring 51 to slide towards the base 311 until it completely covers the fixed machine housing 2. The stepper motor 41 in the arc-shaped groove 48 of the base 311 is then activated. The output of the stepper motor 41 drives the UV lamp 43 at the top of the rotating arm 42 to rotate inside the fixed machine housing 2. During rotation, the UV lamp 43 irradiates the material cylinder 53, fixing it in place. When the irradiation direction needs to be shifted, the locking pin 47 engages with the fixing pin 45, and the operator grasps... The pull rod 44 slides forward. During the sliding process, the fixing pin 45 causes one side of the UV lamp 43 to shift, and the irradiation direction of the UV lamp 43 changes. This changes the traditional direct irradiation method of the material cylinder 53. After the angle of the UV lamp 43 is determined, the locking pin 47 is re-inserted into the horizontal groove 46 on the side of the fixing pin 45 and screwed into the fixing pin 45 to fix the fixing pin 45 to the pull rod 44. The UV lamp 43 rotates at the position of the arc groove 48 on the surface of the base 311. The rotation trajectory is circular with the material cylinder 53 as the center. When irradiating the material cylinder 53, it can improve the light efficiency of the material cylinder 53. The irradiation situation inside the fixed housing 2 can be viewed through the visible panel 52 on the outside of the protective cover 1.

[0035] After the material cylinder 53 is irradiated, the fixed housing 2 is lifted to the top by the hydraulic rod 5, removing the protective cover 1 from the fixed housing 2. When it is necessary to disassemble the support assembly 3, simply unscrew the two sets of hydraulic rods 5 from the top of the support plate 34, and the protective cover 1 can be removed together. Then, move the rotating rod 39 to slide the inside of the base 311 out, and pull the L-shaped straight rod 37 from the bottom of the first ring 36 and the second ring 38, releasing the restriction of the L-shaped straight rod 37 on the first ring 36 and the second ring 38. At this time, the extension block 35 and the support plate 34 can be movably connected. Rotate the support plate 34 to the top and remove the support diagonal brace 32 from the position of the second ring 38. The support plate 34 and the support diagonal brace 32 can be separated, so that the support plate 34 is parallel to the side of the protective cover 1. When it is necessary to support the hydraulic rod 5, the support plate 34 can be installed again.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
