Description

Technical Field

[0001] This application relates to the field of thin-film corona treatment, and in particular to an adjustable thin-film corona treatment device for waste gas. Background Technology

[0002] In the production process of plastic films, some films require the printing of intricate text and patterns on their surface. Corona treatment ensures that the ink adheres firmly and prevents wear and fading during transportation. Corona treatment uses high-voltage discharge to break and degrade the molecular chemical bonds on the surface of the plastic film under the bombardment of high-energy particles. The originally smooth and inert film surface becomes rough and porous, providing more anchor points for the subsequent adhesion of printing materials and meeting production requirements.

[0003] Corona discharge generates a large amount of ozone. On the one hand, the strong oxidizing properties of ozone can over-oxidize the film surface, causing excessive breakage of molecular chains and resulting in embrittlement and powdering of the film surface. On the other hand, excessive ozone may cause color changes on the film surface, affecting its appearance quality. Therefore, it is necessary to install a waste gas treatment device at the corona discharge location to remove the ozone and other waste gases generated by the corona discharge, avoiding negative impacts on the film.

[0004] Currently, most common thin-film corona treatment devices on the market are fixed to the corona generation location using bolts and welding, lacking an adjustment mechanism. This means the angle of the treatment device cannot be adjusted according to actual needs, affecting the efficiency of waste gas treatment. Utility Model Content

[0005] To address the issue that a membrane corona exhaust gas treatment device is rigidly fixed in the corona generation area and cannot adjust its angle according to actual needs, this application provides an adjustable membrane corona exhaust gas treatment device.

[0006] The adjustable thin-film corona discharge exhaust gas treatment device provided in this application adopts the following technical solution:

[0007] An adjustable membrane corona treatment device for exhaust gas includes two upright plates and a housing. Each side of the housing has a receiving mechanism for mounting the housing. An electrocorona roller rotates inside the housing. A support plate is fixed to an adjacent side of the two upright plates. An angle adjustment mechanism is provided between the support plate and the housing. A drive mechanism for the angle adjustment mechanism is provided on the support plate. An air intake pipe is fixed to the housing, and an anti-backflow mechanism is provided on the air intake pipe to prevent exhaust gas backflow.

[0008] By adopting the above technical solution, the receiving mechanism enables the installation of the housing, and the corona roller performs corona treatment on the film. The anti-backflow mechanism prevents the backflow of exhaust gas. The drive mechanism drives the angle adjustment mechanism, allowing the exhaust gas treatment device to adjust its angle as needed, thus solving the problem of existing devices not being able to adjust the angle.

[0009] Preferably, the receiving mechanism includes a connecting rod fixed to the box body and a limiting groove formed on the upright plate, wherein the connecting rod is disposed in the limiting groove.

[0010] By adopting the above technical solution, a receiving mechanism consisting of connecting rods and limiting grooves is set on both sides of the box, which can support and install the box. At the same time, it is conducive to cooperating with the angle adjustment mechanism to adjust the angle of the box, thereby improving the problem that the existing membrane corona exhaust gas treatment device cannot adjust the angle according to actual needs.

[0011] Preferably, the limiting groove includes a first groove and a second groove, the first groove has a rectangular cross-section, the second groove has a semi-circular cross-section, and the diameter of the second groove is the same as the diameter of the connecting rod.

[0012] By adopting the above technical solution, a limiting groove with a specific structure is opened on the upright plate, which consists of a first groove with a rectangular cross-section and a second groove with a semi-circular cross-section and a diameter consistent with that of the connecting rod. This allows the connecting rod installed on the box to be placed in the limiting groove, which helps to install the box more stably, thereby ensuring the stability of the entire waste gas treatment device during operation.

[0013] Preferably, the drive mechanism includes two mounting plates fixed on the support plate, a threaded rod rotating on the two mounting plates, and a rotating handle fixed to one end of the threaded rod, with a nut threadedly connected to the threaded rod.

[0014] By adopting the above technical solution, the rotating handle can drive the threaded rod to rotate, and the threaded connection between the threaded rod and the nut can realize the movement of the nut, providing driving force for the angle adjustment mechanism.

[0015] Preferably, the angle adjustment mechanism includes a half gear fixed on the housing and a toothed plate fixed on the nut. The toothed plate slides on two mounting plates, and the half gear meshes with the toothed plate.

[0016] By adopting the above technical solution, the rotating handle drives the threaded rod to rotate, causing the nut to move, which in turn drives the toothed plate to slide on the mounting plate. Since the half gear meshes with the toothed plate and is fixed on the housing, the angle of the housing can be adjusted, which improves the problem that the membrane corona exhaust gas treatment device is rigidly fixed in the corona generation area and cannot be adjusted according to actual needs, thus improving the exhaust gas treatment efficiency.

[0017] Preferably, the anti-backflow mechanism includes a first pipe connected to one side of the intake pipe and a second pipe disposed on the same side as the first pipe. A one-way check valve is threadedly connected between the first pipe and the second pipe, and the second pipe and the one-way check valve are inclined upwards.

[0018] By adopting the above technical solution, the one-way check valve can prevent the backflow of exhaust gas and prevent the extracted exhaust gas from returning to the corona position. At the same time, the threaded connection facilitates the installation and disassembly of the one-way check valve, making maintenance and replacement convenient. The second pipe slopes upwards towards the one-way check valve, using the gravity of the exhaust gas to further prevent backflow.

[0019] Preferably, the air intake pipe has multiple air intake ports, which are evenly spaced apart.

[0020] By adopting the above technical solution, setting multiple evenly spaced air intakes can more comprehensively and evenly draw in the waste gas generated by the corona discharge, effectively improving the waste gas treatment device's suction effect and treatment efficiency.

[0021] Preferably, the rotating handle is fitted with an anti-slip sleeve.

[0022] By adopting the above technical solution, the anti-slip sleeve on the rotating handle can increase the friction when the hand grips the rotating handle, making it easier and more stable for people to rotate the rotating handle.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up an angle adjustment mechanism and a drive mechanism, the angle of the exhaust gas treatment device can be adjusted according to actual needs, so that the device can be accurately aligned with the exhaust gas generation source, which solves the problem that the existing membrane corona exhaust gas treatment device is rigidly fixed and cannot flexibly adjust the angle.

[0025] 2. By setting the second pipe and the one-way check valve to an upward slope, gravity is used to further prevent exhaust gas backflow, and combined with the one-way check valve, exhaust gas backflow can be effectively avoided. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses an adjustable thin-film corona treatment device for waste gas.

[0036] Reference Figure 1 An adjustable membrane corona treatment device for exhaust gas includes two vertical plates 1, a housing 2, a receiving mechanism 3, a corona roller 4, a support plate 5, and a suction pipe 8. Two sets of receiving mechanisms 3 are provided, positioned on opposite sides of the housing 2. The corona roller 4 is rotatably mounted inside the housing 2, and the suction pipe 8 is fixedly mounted inside the housing 2. The support plate 5 is fixed to an adjacent side of the two vertical plates 1 and is located below the housing 2.

[0037] Reference Figure 1 The corona roller 4 is connected to the housing 2 via bearings, ensuring its flexible rotation. The rotation of the corona roller 4 applies a uniform corona treatment to the film, roughening its surface to facilitate subsequent, secure printing of patterns and prevent the patterns from peeling off. The receiving mechanism 3 allows for quick and easy attachment of the housing 2 to the upright plate 1, providing support for the housing 2 and facilitating its installation. Furthermore, the receiving mechanism 3 provides a base for subsequent angle adjustments.

[0038] Reference Figure 1 and Figure 2A backflow prevention mechanism 9 is installed on the intake pipe 8 to prevent exhaust gas from flowing back and improve exhaust gas treatment efficiency. An angle adjustment mechanism 6 and a drive mechanism 7 are installed between the housing 2 and the support plate 5, with the angle adjustment mechanism 6 positioned above the drive mechanism 7. The drive mechanism 7 provides a power source to the angle adjustment mechanism 6, enabling it to operate and adjust the angle of the housing 2, allowing the exhaust gas treatment device to more precisely align with the exhaust gas source and effectively collect the exhaust gas.

[0039] Reference Figure 3 The receiving mechanism 3 includes a connecting rod 31 fixed to the housing 2 and a limiting groove 32 formed in the upright plate 1. The connecting rod 31 is generally made of metal, such as stainless steel, which has good strength and corrosion resistance. The connecting rod 31 is fixed to the housing 2 by welding or bolting. The limiting groove 32 is formed at the top of the upright plate 1. When installing the housing 2, the connecting rod 31 is first aligned with the limiting groove 32 and then slid into the bottom of the limiting groove 32 from the top of the upright plate 1. The limiting groove 32 serves to restrict the position of the connecting rod 31, completing the initial installation of the housing 2.

[0040] Reference Figure 3 The limiting groove 32 on the upright plate 1 includes a first groove 321 and a second groove 322. The first groove 321 has a rectangular cross-section, and the second groove 322 has a semi-circular cross-section. The diameter of the second groove 322 is the same as the diameter of the connecting rod 31. The first groove 321 mainly guides the movement direction of the connecting rod 31; its rectangular cross-section ensures smooth sliding within it. The second groove 322 serves for positioning and support; its semi-circular cross-section not only ensures a high degree of fit between the second groove 322 and the connecting rod 31, reducing wear, but also allows the connecting rod 31 to rotate within the second groove 322, providing a base for the rotation of the housing 2 of the angle adjustment mechanism 6.

[0041] Reference Figure 2 and Figure 4 The drive mechanism 7 includes two mounting plates 71 fixed to the support plate 5, a threaded rod 72 rotating on the two mounting plates 71, and a rotating handle 73 fixed to one end of the threaded rod 72. A nut 74 is also threadedly connected to the threaded rod 72. The mounting plates 71 are generally made of metal and are fixed to the support plate 5 by welding or bolting, providing support and rotation space for the threaded rod 72. The threaded rod 72 is a key component of the transmission, with threads machined on its surface, and cooperates with the nut 74 to achieve linear motion. In addition, an anti-slip sleeve 11 made of rubber is fitted on the rotating handle 73 to increase friction and prevent hand slippage. With the threaded engagement between the nut 74 and the threaded rod 72, when the threaded rod 72 is rotated, the nut 74 will move linearly along the threaded rod 72. By changing the direction of rotation of the rotating handle 73, the direction of movement of the nut 74 is changed.

[0042] Reference Figure 2 and Figure 4 The angle adjustment mechanism 6 includes a half gear 61 fixed to the housing 2 and a toothed plate 62 fixed to the nut 74. The toothed plate 62 slides on two mounting plates 71, and the half gear 61 meshes with the toothed plate 62. The half gear 61 and the toothed plate 62 are generally made of metal to ensure sufficient strength and wear resistance. The half gear 61 is fixed to the housing 2 by welding or bolts, so that the rotation of the half gear 61 drives the housing 2 to rotate synchronously.

[0043] Reference Figure 2 and Figure 4 By rotating the handle 73, the threaded rod 72 is driven to rotate, and under the action of the threaded connection, the nut 74 moves linearly synchronously on the threaded rod 72. When the nut 74 moves linearly under the drive of the threaded rod 72, since the toothed plate 62 is fixedly connected to the nut 74, it will cause the toothed plate 62 to slide on the mounting plate 71. The meshing of the half gear 61 and the toothed plate 62 converts the linear motion of the toothed plate 62 into the rotation of the half gear 61, thereby driving the housing 2 to rotate, realizing the angle adjustment of the housing 2, making the exhaust gas treatment device more accurately aligned with the corona generation position, and improving the exhaust gas treatment efficiency.

[0044] Reference Figure 5 A groove matching the toothed plate 62 is provided on the mounting plate 71, so that the toothed plate 62 can slide on the mounting plate 71. This allows the mounting plate 71 to limit the movement of the toothed plate 62, prevent the toothed plate 62 from shifting during movement, and avoid affecting the meshing of the toothed plate 62 with the half gear 61, thereby affecting the angle adjustment of the housing 2.

[0045] Reference Figure 6 The suction pipe 8 is fixed to the housing 2, and multiple suction ports 10 are provided on the suction pipe 8, which are evenly spaced. The suction pipe 8 is generally made of metal or plastic, and the suction ports 10 are used to draw in the waste gas generated during the corona treatment process. The evenly spaced suction ports 10 can make the waste gas be drawn in more evenly, thereby improving the waste gas collection efficiency.

[0046] Reference Figure 6The backflow prevention mechanism 9 includes a first pipe 91 connected to one side of the suction pipe 8 and a second pipe 92 disposed on the same side as the first pipe 91. Furthermore, a one-way check valve 93 is threadedly connected between the first pipe 91 and the second pipe 92, and the second pipe 92 and the one-way check valve are inclined upwards. The threaded connection of the second pipe 92 allows it to be connected to the pipe of an external suction device, facilitating suction at the location where the corona occurs. Since the one-way check valve 93 only allows exhaust gas to flow in one direction, it can only allow exhaust gas to flow towards the external suction box, preventing exhaust gas backflow. In addition, the upward slope design of the second pipe 92 utilizes the gravity of the exhaust gas to assist it in flowing quickly through the one-way check valve 93, further preventing exhaust gas backflow.

[0047] The implementation principle of the adjustable thin-film corona discharge exhaust gas treatment device according to this application embodiment is as follows: The receiving mechanism 3 initially mounts the housing 2 onto the upright plate 1, providing a rotational basis for subsequent angle adjustment. With the cooperation of the drive mechanism 7 and the angle adjustment mechanism 6, the operator can flexibly adjust the angle of the housing 2 according to actual needs, allowing the suction pipe 8 to be better aligned with the exhaust gas source, thus improving exhaust gas treatment efficiency. Compared with traditional rigid fixing devices, this greatly enhances the applicability of the exhaust gas treatment device.
