Description

Technical Field

[0001] This utility model relates to the technical field of coating and curing integrated machines, specifically to a coating and curing integrated machine for polyester film and silicone tape. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. This machine coats a roll of substrate with a layer of adhesive, paint or ink with a specific function, and then dries and rewinds it. Coating machines are also essential equipment for the production of silicone tapes.

[0003] A search revealed existing technology (publication number: CN217289036U), which describes "an adjustable silicone tape coating machine, comprising a machine body, a top plate mounted on the top of the machine body, a second coating roller and a first coating roller, a width adjustment component for adjusting the interval between the two first coating rollers mounted on the top plate; the second coating roller is located below the first coating roller, and a height adjustment component for adjusting the height of the second coating roller is mounted on the machine body; the feed nozzle corresponds to the first coating roller, and the discharge nozzle corresponds to the second coating roller; the coating machine of this utility model is equipped with a width adjustment component for adjusting the interval between the two first coating rollers, so that the inner space of the two first coating rollers can accommodate silicone tapes of different thicknesses, with a wide range of applications, and can meet the production needs of silicone tapes of different thicknesses; a height adjustment component is provided for adjusting the height of the second coating roller, thereby appropriately adjusting the tightness of the silicone tape material, further meeting different production needs."

[0004] While existing coating machines for silicone tape production have achieved the desired height and tightness of the coating rollers, they still have some shortcomings: Existing coating machines require curing after coating, and existing curing methods include thermosetting and UV curing. However, these methods are not convenient for switching between different curing methods to achieve different curing speeds for different silicone film materials. Furthermore, during thermosetting, temperature and time also need to be adjusted to suit different silicone film materials. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a coating and curing machine for polyester film and silicone tape is provided to solve the problems mentioned in the background.

[0006] To achieve the above objectives, a coating and curing integrated machine for polyester film silicone tape is provided, comprising: a frame, a coating machine and a curing device at the upper end of the frame, the curing device including a rectangular box, a fan on the upper side of the rectangular box, a heater connected to the air outlet side of the fan, and an air duct connected to the air outlet side of the heater, the other end of the air duct being inserted into the interior of the curing device and connected to the air box, a guide hood connected to one side of the air box, and an ultraviolet lamp between the air boxes, with brackets connected to both ends of the ultraviolet lamp, and the brackets respectively installed on the upper and lower inner walls of the rectangular box, an air outlet opening on the inner side of the guide hood, a valve plate inside the guide hood, and the outer end of the valve plate being connected to a dual-axis cylinder via a connecting rod, while the dual-axis cylinder is fixed to the outer wall of the guide hood.

[0007] Furthermore, the rectangular box included in the curing device has guide grooves on both sides of its side walls, and the guide grooves are located between the upper and lower ultraviolet lamps.

[0008] Furthermore, the air outlet of the heater is connected to a T-junction, and the air ducts are symmetrically connected to both ends of the T-junction.

[0009] Furthermore, the bellows is fixed to the inner wall of the curing device by a fixing rod, and the bellows is designed as a hollow box structure.

[0010] Furthermore, the flow guide is designed as a hollow trapezoidal box structure, and the flow guide is connected to the inner cavity of the air box. Additionally, the flow guide is connected to two sets of upper and lower sections on the outer side of the same air box.

[0011] Furthermore, the valve plate is slidably inserted into the insertion holes at both ends of the flow guide, and the upper and lower end faces of the valve plate are provided with sealing strips corresponding to its length.

[0012] Furthermore, the upper side of the frame is provided with a silicone tape material guide roller, and the coating machine is located between the guide roller and the curing device.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The silicone tape is first coated using a coating machine, and then it enters the curing device through a guide groove. At this time, the silicone tape passes between the ultraviolet lamp and the guide hood. Depending on the material of the silicone tape, if the material of the silicone tape requires slow curing, air can be introduced into the heater through a fan, and then the heated air is conducted into the heat box through the air duct. Then, the guide hood blows the hot air onto the upper and lower surfaces of the silicone tape to achieve slow curing. If the silicone tape requires fast curing, the ultraviolet lamp is turned on to achieve rapid curing of the coated silicone tape.

[0015] 2. During high-temperature curing, the heating temperature is adjusted by the heater according to the different silicone tape materials. Then, the valve plate is moved by starting the dual-axis cylinder, which in turn adjusts the air volume of the air outlet. This allows for adjustment of the contact time between the air and the hot air, reducing the area through which the hot air passes the silicone tape and thus adapting to the curing effect of different silicone tape materials.

A heater 32 is connected to the air outlet side of the fan 31, and an air duct 33 is connected to the air outlet side of the heater 32. The other end of the air duct 33 is inserted into the curing device 3. The internal structure is connected to the bellows 34, and a guide shroud 341 is connected to one side of the bellows 34. An ultraviolet lamp 37 is provided between the bellows 34. The two ends of the ultraviolet lamp 37 are connected to the brackets 36, and the brackets 36 are respectively installed on the upper and lower inner walls of the rectangular box. An air outlet 342 is opened on the inner side of the guide shroud 341, and a valve plate 345 is provided inside the guide shroud 341. The outer end of the valve plate 345 is connected to the dual-axis cylinder 343 through the connecting rod 344. At the same time, the dual-axis cylinder 343 is fixed to the outer wall of the guide shroud 341.

[0022] In this embodiment, the frame 1, the coating device 2, and the curing device 3 constitute the integrated coating and curing machine for polyester film silicone tape involved in this application.

[0023] The coating machine 2 uses a coating machine device with existing technology, and a winding device is provided on one side of the curing device 3 to realize the traction and winding of the cured silicone tape.

[0024] Specifically, the heater 32 adopts an electric heating device, which together with the fan 31 forms an electric hot air fan structure in the prior art to heat the outside air. At the same time, an air filter device (not shown in the figure) is provided on the air inlet side of the fan 31 to remove dust and filter the outside air to prevent contamination of the silicone belt.

[0025] Specifically, the curing device 3 includes a rectangular box with a closed structure, which allows the heating air to be temporarily held inside to maintain the temperature inside the rectangular box.

[0026] like Figure 2 , Figure 3 and Figure 4 In the curing device 3, the rectangular box includes guide grooves 38 on both sides of the box wall, and the guide grooves 38 are located in the middle of the upper and lower ultraviolet lamps 37. The air outlet of the heater 32 is connected to a tee, and the air duct 33 is symmetrically connected to both ends of the tee. The air box 34 is fixed to the inner wall of the curing device 3 by a fixing rod 35, and the air box 34 is a hollow box structure. The guide hood 341 is a hollow trapezoidal box structure, and the guide hood 341 is connected to the inner cavity of the air box 34. The guide hood 341 is connected to two sets of upper and lower parts on the outside of the same air box 34. The valve plate 345 is slidably inserted into the insertion holes opened at both ends of the guide hood 341, and the upper and lower end faces of the valve plate 345 are provided with sealing strips corresponding to their lengths.

[0027] Specifically, guide grooves 38 are symmetrically opened on both sides of the rectangular box to realize the feeding and discharging of silicone strips.

[0028] Specifically, the air box 34 is designed as a sealed box structure, which allows heated air to be introduced into the guide shroud 341, and then the hot air is blown onto the upper and lower surfaces of the silicone strip at the same time.

[0029] As a preferred implementation, the valve plate 345 is driven by a dual-axis cylinder 343, thereby adjusting the air volume of the air outlet 342.

[0030] In use, the silicone tape is first coated using a coating machine, and then enters the curing device through a guide groove. The silicone tape passes between a UV lamp and a flow guide. Depending on the material of the silicone tape, if slow curing is required, air is introduced into the heater via a fan, heated, and then transferred to a heat exchanger via a duct. The flow guide then directs the hot air onto the upper and lower surfaces of the silicone tape for slow curing. If rapid curing is needed, the UV lamp is activated for fast curing. For high-temperature curing, the heating temperature is adjusted using the heater based on the silicone tape material. A dual-axis cylinder moves a valve plate, adjusting the airflow from the outlet to control the contact time with the hot air. This reduces the area of ​​the hot air passing over the silicone tape, facilitating curing effects for different silicone tape materials.

[0031] The integrated coating and curing machine for polyester film and silicone tape of this invention can effectively solve the problems mentioned in the background technology. Based on the existing integrated coating and curing machine technology for polyester film and silicone tape, it has the ability to select the curing speed and to easily adjust the curing temperature and time according to the material of the silicone tape.
