Description

Technical Field

[0001] This utility model relates to the field of coating machine drying, specifically to a hot air drying device for a coating machine. Background Technology

[0002] A Chinese patent proposes a dryer for adhesive tape coating (application number: CN202223279077.6). The adhesive tape substrate is sequentially conveyed through a coating mechanism, a housing, and a drive mechanism. The housing has through holes at both its front and rear ends for the substrate to pass through. Two drying chambers are spaced apart on the inner wall of one side of the housing along the substrate conveying direction. A first drying chamber is connected to the air outlet of each drying chamber. A second drying chamber is symmetrically arranged below the first drying chamber, spanning across the substrate. The end of the first drying chamber furthest from the drying chamber is connected to the second drying chamber via a connecting air box. Both the first and second drying chambers have several exhaust holes spaced apart along the width of the substrate on their surfaces facing the substrate. This invention ensures both the uniformity of the coating distribution on the substrate and improves the uniformity and stability of the adhesion between the coating layer and the substrate.

[0003] Existing coating machine drying devices typically employ fixed hot air nozzles to continuously blow air onto the moving coating material for drying. However, this structure suffers from uneven drying, localized under-drying, or over-drying, making it particularly difficult to achieve precise heating of specific areas, especially when processing special coatings or requiring high-precision drying control. Furthermore, the fixed air outlet structure cannot be dynamically adjusted according to the coating position or drying requirements, limiting the improvement of drying efficiency and product quality.

[0004] Therefore, a hot air drying device that can achieve localized precise heating and adjustable air outlet position is needed to improve the uniformity and control accuracy of coating drying. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a hot air drying device for a coating machine.

[0006] The technical solution of this utility model is as follows: This utility model provides a hot air drying device for a coating machine, including a support base. Two transmission boxes are symmetrically arranged on the top of the support base. A transmission seat is provided outside the transmission box. A protective shell is provided between the two transmission boxes. A transmission bar is provided outside the protective shell. Moving cylinders are provided on both sides of the transmission boxes.

[0007] Optionally, the transmission box has a transmission hole on its exterior, the support base has a ventilation transmission hole at its bottom and the protective shell has a venting plate at its top, and the support base has a venting plate on both sides at its bottom. The protective shell is made of transparent material.

[0008] Optionally, the two transmission seats connected to the transmission box are located on both sides of the transmission hole opened in the transmission box, and the transmission seat is rotatably connected to the transmission rod inside.

[0009] Optionally, the transmission box is fixedly connected to the movable cylinder, the movable block is slidably connected to the movable cylinder, a movable support block is fixedly connected to the other end of the movable cylinder, and a stabilizing wire is provided on the outside of the movable cylinder. The stabilizing wire is threaded to the movable cylinder and fixes its position by contacting the movable block.

[0010] Optionally, the telescopic block is fixedly connected to the transmission box, a telescopic rod is fixedly connected to the output end of the telescopic block, the other end of the telescopic rod is fixedly connected to the moving ring, a transmission groove is provided on the outside of the transmission bar, and the moving ring is slidably connected to the transmission bar.

[0012] Optionally, the air outlet box and the moving ring are connected by a transmission rod, and both the transmission rod and the moving ring are tubular inside.

[0013] The beneficial effects achieved by this utility model are as follows: This invention, by setting an adjustable moving ring and an exhaust box, can control the exhaust position of high-temperature gas, enabling reciprocating heating and drying of specific areas of the coating material. It is especially suitable for localized areas requiring focused drying, significantly improving drying accuracy. The moving ring drives the exhaust box to move back and forth, ensuring that the hot air is evenly distributed on the surface of the coating material, avoiding the problems of localized overheating or insufficient drying caused by traditional fixed exhaust. This effectively improves the drying uniformity of the coating. Furthermore, the fabric strip can be stopped during the drying process, and combined with the reciprocating motion of the moving ring, static precision drying is achieved, adapting to different coating process requirements and improving the applicability and process flexibility of the equipment.

[0016] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0017] Example 1 like Figure 1-4 As shown, this utility model provides a hot air drying device for a coating machine, including a support base 1. Two transmission boxes 101 are symmetrically arranged on the top of the support base 1. A transmission seat 2 is arranged outside the transmission box 101. A protective shell 3 is arranged between the two transmission boxes 101. A transmission bar 4 is arranged outside the protective shell 3. A movable cylinder 5 is arranged on both sides of the transmission box 101. A movable block 6 is arranged outside the movable cylinder 5. A telescopic block 7 is arranged on one side of one of the transmission boxes 101. A movable ring 10 is arranged outside the support base 1 and the protective shell 3. A heating box 8 is arranged outside the movable ring 10. A fan 9 is arranged outside the heating box 8. The bottom wall of the inner cavity of the movable ring 10 and the top wall of the inner cavity of the movable ring 10 are respectively connected to an air outlet box 11.

[0018] This invention, by setting an adjustable moving ring 10 and an exhaust box 11, can control the exhaust position of high-temperature gas, realizing reciprocating heating and drying of specific areas of the coating material. It is especially suitable for local areas that require focused drying, significantly improving drying accuracy. The moving ring 10 drives the exhaust box 11 to move back and forth, so that the hot air is evenly distributed on the surface of the coating material, avoiding the problems of local overheating or insufficient drying caused by traditional fixed exhaust. This effectively improves the drying uniformity of the coating. Furthermore, the fabric strip can be stopped during the drying process. Combined with the reciprocating motion of the moving ring 10, static precision drying is achieved, adapting to different coating process requirements and improving the applicability and process flexibility of the equipment.

[0019] Example 2 like Figure 1-2 and Figure 4 As shown, the transmission box 101 has a transmission hole on its exterior, and the support base 1 and the protective shell 3 both have ventilation transmission holes 102. The bottom sides of the support base 1 are connected to air leakage plates 103. The protective shell 3 is made of transparent material.

[0020] Specifically, the transmission box 101, the vent transmission hole 102, and the vent plate 103 work together to control gas output. Furthermore, the design of the vent transmission hole 102 not only facilitates gas flow but also optimizes the overall ventilation efficiency. The vent plate 103 ensures controllable gas output. During operation, the tight fit between the transmission box 101 and the protective shell 3 ensures the safety and stability of the internal components, effectively preventing performance degradation or malfunctions caused by external interference. The transparent material of the protective shell 3 allows for easy external observation of the drying effect.

[0021] In this embodiment, the two transmission seats 2 connected to the transmission box 101 are located on both sides of the transmission hole opened in the transmission box 101, and the transmission seat 2 is rotatably connected to the transmission rod 201. The protective shell 3 is divided into multiple plates and is detachably connected to the support seat 1.

[0022] Specifically, the transmission rod 201 can be used to assist in the transmission of the fabric strip, ensuring that the fabric strip is stable and efficient during the transmission process. At the same time, the detachable protective shell 3 allows for easy adjustment of the fabric strip in the protective shell 3 or the transmission box 101 area, facilitating subsequent control of the transmission.

[0023] In this embodiment, the transmission box 101 is fixedly connected to the movable cylinder 5, the movable block 6 is slidably connected to the movable cylinder 5, the other end of the movable cylinder 5 is fixedly connected to the movable support block 601, and the outside of the movable cylinder 5 is provided with a stabilizing wire 501, which is threaded to the movable cylinder 5 and fixes its position by contacting the movable block 6.

[0024] Specifically, the connection between the movable cylinder 5 and the movable block 6 can be used to control the relative movement of the movable block 6. The movable support block 601 facilitates connection with other components, and the stabilizing wire 501 can control the stability and position of the movable block 6 to ensure a stable connection.

[0025] Example 3 like Figure 1-3 As shown, the telescopic block 7 is fixedly connected to the transmission box 101, the output end of the telescopic block 7 is fixedly connected to the telescopic rod 701, the other end of the telescopic rod 701 is fixedly connected to the moving ring 10, the transmission bar 4 has a transmission groove 401 on its outside, and the moving ring 10 is slidably connected to the transmission bar 4.

[0026] Specifically, the telescopic block 7 allows for easy control of the connection of objects, and the transmission groove 401 controls the sliding of the moving ring 10 along the transmission bar 4, making it easy to adjust the position of the moving ring 10 and making subsequent adjustments more convenient and faster.

[0027] In this embodiment, the heating box 8 is fixedly connected to the moving ring 10. Heating elements are installed inside the heating box 8. The fan 9 is connected to the heating box 8. An air inlet 901 is connected to one side of the fan 9. A drive motor 902 is fixedly connected to the outside of the fan 9.

[0028] Specifically, the fan 9, in conjunction with the drive motor 902, allows gas to enter through the air inlet 901. The incoming gas is then heated by heating elements within the heating chamber 8, facilitating control of the heating process. The heated gas is then discharged through the fan 9, achieving hot air drying for the coating machine. The design of the heating chamber 8 ensures more uniform heating, guaranteeing effective drying of the material on the coating machine. Simultaneously, the drive motor 902 precisely controls the speed of the fan 9, thereby adjusting the flow rate and temperature of the hot air to meet the needs of different coating processes.

[0029] In this embodiment, the air outlet box 11 and the moving ring 10 are connected by a transmission rod 1101, and both the transmission rod 1101 and the moving ring 10 are tubular inside.

[0030] Specifically, the connection between the moving ring 10 and the transmission rod 1101 facilitates gas transmission control, ensuring a more uniform gas distribution on the coating machine. The flexible movement of the moving ring 10 allows the gas to be transmitted along a predetermined path and within a predetermined range.

[0031] In summary, the transmission seat 2 provided in this application can assist the movement of the fabric strip. The telescopic block 7 controls the adjustment and movement of the moving ring 10. The heating box 8 and the fan 9, in conjunction with the moving ring 10 and the air outlet box 11, can discharge heated gas in the support seat 1. The movable moving ring 10 can control the reciprocating movement of the air outlet box 11. The high-temperature gas discharged from the air outlet box 11 achieves the drying effect. In a specific mode, the fabric strip can be controlled to stop transmission for local reciprocating drying, thereby achieving precise coating drying effect through reciprocating heating and drying at specific locations.
