Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a device for improving the dyne value of wide-width plates. Background Art

[0002] Honeycomb panels are one of the ceiling decoration techniques with light weight, high strength, thin thickness, convenient construction, and good sound insulation, heat insulation, corrosion resistance, moisture resistance, and fire retardancy. Honeycomb panels have a honeycomb sandwich structure, consisting of a panel, a honeycomb core, and a bottom plate, that is, a double-layer aluminum alloy plate and a honeycomb core. The aluminum alloy plate and the honeycomb core are usually combined together by a glue coating layer. In order to enhance the adhesion of the aluminum alloy plate, more manufacturers are trying to improve the viscosity of the glue.

[0003] At present, there are devices on the market for corona treatment of some boards to increase the dyne value of the board surface, thereby improving the bonding strength between the board and the adhesive.

[0004] However, this type of corona device is currently only suitable for small plates, and is not suitable for large and wide plates, especially large and wide conductive metal plates. Take the aluminum alloy plate used to produce large honeycomb plates as an example. When the aluminum alloy plate is transmitted through the corona device, the plate may be arched due to its large length and width and small thickness, and the friction force at various locations during the transmission process is not completely consistent. Once the plate touches the electrode system, it will cause the risk of electric shock, causing personal injury or equipment damage; and it will destroy the normal gap between the electrode and the plate surface, affecting the stability and effect of corona discharge, resulting in poor adhesion on the plate surface. Utility Model Content

[0005] The main purpose of the utility model is to provide a device for improving the dyne value of wide-width plates, aiming to prevent the plates from touching electrodes and affecting the corona treatment effect.

[0006] In order to achieve the above-mentioned purpose, the utility model proposes a device for improving the dyne value of wide-width plates, comprising:

[0007] frame;

[0008] Conveyor platform for transporting wide panels; and

[0009] A corona device is arranged above the transmission platform, and comprises a fixing frame, wherein the fixing frame is rotatably connected with a clamping structure, and the clamping structure comprises a plurality of extrusion pieces arranged at intervals, and an electrode tube is arranged between every two adjacent extrusion pieces.

[0010] In one embodiment of the present application, the distance between the lowest end of the extrusion member and the transmission platform is smaller than the distance between the lowest end of the electrode tube and the transmission platform, and a plurality of extrusion members arranged at intervals ensure that the warping height of the wide-width plate is always lower than the lowest end of the electrode tube.

[0011] In one embodiment of the present application, the transmission platform includes a plurality of transmission rollers arranged in sequence and rotatably connected to a frame, and the extrusion member is disposed above a gap formed between two adjacent transmission rollers.

[0012] In one embodiment of the present application, the extrusion member is a pressure roller;

[0013] Or the extrusion member is a plurality of linearly arranged universal balls.

[0014] In one embodiment of the present application, the end portion of the extrusion is provided with an insulating material;

[0015] Furthermore, the transmission roller sleeve located directly below the electrode tube is provided with insulating material.

[0016] In one embodiment of the present application, when the extrusion member is a pressure roller, the pressure roller is connected to a pressure roller drive motor that drives it to rotate, and the transmission roller is connected to a transmission roller drive motor that drives it to rotate. The speed at which the pressure roller conveys the plate is the same as the speed at which the transmission roller conveys the plate, and the pressure roller drive motor and the transmission roller drive motor are the same motor or different motors.

[0017] In one embodiment of the present application, the corona device further comprises an adjusting structure, two ends of which are respectively connected to the fixing frame and the frame, for adjusting the distance between the pressing structure and the transmission platform.

[0018] In one embodiment of the present application, the frame is provided with auxiliary rollers located on both sides of the clamping structure, and the auxiliary rollers are distributed along the conveying direction of the plate.

[0019] In one embodiment of the present application, the corona device further comprises a corona drive motor;

[0020] Each electrode tube comprises an electric core, a metal sleeve fixedly sleeved on the electric core, and an insulating sleeve fixed on the metal sleeve; each electric core is linked to a corona driving motor.

[0021] The technical solution of the utility model adopts a clamping structure arranged above the transmission device, the clamping structure includes a plurality of extrusions arranged at intervals, and the electrode tube is arranged between two adjacent extrusions, so as to prevent the plate from arching during the transmission process and touching the electrode tube, causing mechanical damage to the electrode system or circuit short circuit, affecting the normal operation of the corona device; it can also avoid damaging the normal gap between the plate and the surface of the electrode tube and affecting the stability and effect of the corona discharge. The utility model enables the entire equipment to produce and process large and wide conductive metal plates. Without using higher quality glue, the large honeycomb plates produced by the above equipment are first corona treated, which greatly improves the dyne value. After the treatment, the glue is applied and the honeycomb panels are installed as soon as possible, so that the use of ordinary glue can greatly improve the adhesion between the aluminum alloy plate and the honeycomb panel.

[0022] In summary, the application of the above equipment can greatly reduce the production cost of products such as honeycomb panels, while greatly improving the quality of the products. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] Combined with reference Figures 1 to 3 As shown, the utility model proposes a device for improving the dyne value of wide-width plate, comprising a frame 10; a transmission device 20, the transmission device 20 comprises a plurality of drive rollers 21 arranged in sequence and all rotatably connected to the frame 10 to form a transmission platform 210 for the wide-width plate; and a corona device 30, the corona device 30 is arranged above the transmission platform 210, the corona device 30 comprises a fixed frame 31 connected to the frame 10, the fixed frame 31 is rotatably connected to a clamping structure 32, the clamping structure 32 comprises a plurality of extrusion members 321 arranged at intervals, an electrode tube 33 is arranged between two adjacent extrusion members 321, and the plurality of extrusion members 321 arranged at intervals make the warping height of the wide-width plate always lower than the lowest end of the electrode tube 33.

[0033] It should be noted here that the number and spacing of the extrusion pieces 321 are determined according to the thickness of the plate, whether it is easy to warp / arch, and the height of the warp / arch. When using the device, the warp / arch height of the wide plate should always be lower than the lowest end of the electrode tube 33 to avoid burning the electrode tube 33 or even the entire device. At the same time, the distance from the lowest end of the electrode tube 33 to the plate should be set according to the parameter requirements of the electrode tube 33 manufacturer. On the one hand, it is necessary to avoid the electrode tube 33 from not being able to penetrate the plate, and on the other hand, it is necessary to avoid contact between the two and burning the electrode tube.

[0034] The corona device 30 also includes a corona drive motor (not shown); each electrode tube includes a battery core (not shown), a metal sleeve (not shown) fixedly mounted on the battery core, and an insulating sleeve (not shown) fixed on the metal sleeve; each battery core is linked to the corona drive motor. The corona drive motor can be connected to each electrode tube 33 through a belt drive, so that each electrode tube 33 keeps rotating synchronously.

[0035] It should be noted here that when the electrode tube 33 is powered on, the electrode tube 33 performs discharge work toward the lowest end of the transmission roller 21. If the electrode tube 33 does not rotate, the electrode tube 33 always performs discharge work at this position. After a period of use, the battery cell will break through the insulating sleeve corresponding to this position, thereby causing a short circuit or even the risk of equipment burning. If the electrode tube 33 can be kept in a rotating state, different parts of the electrode tube 33 will be located at the lowest end of the transmission roller 21 in turn. After the electrode tube 33 is discharged, it will immediately rotate out of the discharge position. During one rotation, the part that has just been discharged can be dissipated, so that the insulating sleeve outside the electrode tube 33 will not be broken, which prolongs the service life of the electrode tube 33 and avoids the occurrence of short circuits or equipment damage caused by the breakdown of the insulating sleeve.

[0036] Combined with reference Figure 1 As shown, the frame 10 can be a metal square frame, and a plurality of sequentially arranged transmission rollers 21 are arranged above the frame 10. The transmission rollers 21 can be driven to rotate by a motor, and two adjacent transmission rollers 21 can be connected by belts, chains or gears to form a transmission platform 210 for actively transmitting wide-width plates. The transmission platform 210 can also be a conveyor belt. It should be noted that the wide-width plates here can be aluminum alloy plates with a width greater than one meter, which are collectively referred to as plates below. The plates are moved and transported by the rotation of the transmission rollers 21. A corona device 30 is arranged above the transmission platform 210. The specific structure of the corona device 30 refers to the prior art and is not repeated here. In this embodiment, the corona device 30 also includes a fixed frame 31 connected to the frame 10. The fixed frame 31 can be a metal frame. A clamping structure 32 is rotatably connected to the fixed frame 31. The clamping structure 32 can include a plurality of extrusions 321 arranged at intervals, and a transmission gap for the plates to pass through is formed between the extrusions 321 and the transmission platform 210. Since the width and length of wide plates are large, if there is local uneven force during the transmission process, it may cause the plate to be partially arched. The clamping structure 32 provided above the transmission platform 210 can offset or alleviate the occurrence of local arching of the plate, or the height of the arching is lower than the height of the clamping structure 32 relative to the transmission platform 210. The electrode tube 33 can be provided between two adjacent extrusion members 321. Since there are extrusion members 321 on both sides of the electrode tube 33, the arched plate can be effectively prevented from touching the electrode tube 33, thereby ensuring the safety of operation and the stability of the processing effect.

[0037] The extrusion member 321 and the driving roller 21 are arranged in a staggered manner, that is, the extrusion member 321 is arranged above the gap formed between two adjacent driving rollers 21 .

[0038] Combined with reference Figure 1 and Figure 2As shown, when the transmission roller 21 rotates, friction is generated between the plate and the transmission roller 21, thereby driving the plate to move. The rotation speeds of different transmission rollers 21 cannot be guaranteed to be completely consistent. If the rotation speeds of two adjacent transmission rollers are different, the plate will be arched between them. Therefore, the extrusion member 321 and the transmission roller 21 can be staggered to prevent the plate from touching the electrode tube 33 after arching, causing damage to the electrode tube 33, or affecting the corona effect.

[0039] The extrusion member 321 can be a pressing roller or an extrusion mechanism formed by a plurality of universal balls arranged linearly. Both the pressing roller and the universal balls rotate passively under the friction of the plate to offset the force of the plate arching, so that the plate is always transported in a straight state.

[0040] When the extrusion member 321 is a pinch roller, the pinch roller is connected to a pinch roller driving motor for driving it to rotate, and the transmission roller is connected to a transmission roller driving motor for driving it to rotate. The speed at which the pinch roller conveys the plate is the same as the speed at which the transmission roller conveys the plate.

[0041] It should be noted here that the pressure roller does not need to be additionally connected to a motor, but considering that when conveying the plate, there may be slight arching / warping on the surface of the plate, or some impurities attached to the surface, thus affecting the conveying efficiency of the plate, in order to avoid such a situation, it is preferred that both the pressure roller and the transmission roller are connected to a drive motor, and the drive motors connected to each of them can be the same motor or two different motors that can drive the two to maintain a synchronous conveying speed.

[0042] The distance between the extrusion member 321 and the transport platform 210 is smaller than the distance between the electrode tube 33 and the transport platform 210 .

[0043] Combined with reference Figure 2 and Figure 3 As shown, the lower edge of the extrusion piece 321 is lower than the lower edge of the electrode tube 33. As mentioned above, the plate is usually arched between the two drive rollers 21 due to the asynchronous rotation speed or uneven friction between the two drive rollers 21. The extrusion piece 321 is located between two adjacent drive rollers 21, which can press the arched part downward. The distance between the extrusion piece 321 and the transmission platform 210 is smaller than the distance between the electrode tube 33 and the transmission platform 210, which can ensure that the height of the arched plate does not exceed the height of the extrusion piece 321. The distance between the electrode tube 33 and the transmission platform 210 is greater than the distance between the extrusion piece 321 and the transmission platform 210, which can prevent the plate from touching the electrode tube 33 after arching, resulting in safety hazards or damage to equipment or reduced processing effect.

[0044] It should be noted that the extrusion piece 321 and the fixing frame 31 are rotatably connected. When the plate is arched, the arched part is not directly pressed down, but the arched part drives the extrusion piece 321 to passively rotate and then smoothly move downward and continue to be transmitted forward, which will not affect the normal transmission of the plate.

[0045] In one embodiment of the present application, an end portion of the extrusion member 321 close to the electrode tube 33 is provided with an insulating material, and a transmission roller disposed toward the electrode tube 33 is also provided with an insulating material.

[0046] Usually, insulating materials need to be set near the electrode tube 33 to ensure safety and stability. Insulating materials such as rubber, plastic, and glass fiber can be set in the part of the extrusion piece 321 close to the electrode tube 33 to isolate the electrode tube 33 from the surrounding environment and prevent the electric field from interfering with and damaging the extrusion piece 321.

[0047] In one embodiment of the present application, the corona device 30 further includes an adjustment structure 34 , both ends of which are respectively connected to the fixing frame 31 and the frame 10 , for adjusting the distance between the pressing structure 32 and the transmission platform 210 .

[0048] Combined with reference Figure 3 As shown, the adjustment structure 34 can be a screw nut structure, which drives the screw to move to adjust the distance between the clamping structure 32 and the transmission platform 210; it can also be a worm gear structure, which drives the fixed frame 31 to move by the worm to adjust the distance between the clamping structure 32 and the transmission platform 210. By adjusting the distance between the clamping structure 32 and the transmission platform 210, the processing requirements of plates of different thicknesses can be met, and the distance between the electrode tube 33 and the plate during corona treatment can also be adjusted to improve the corona treatment effect.

[0049] In one embodiment of the present application, auxiliary rollers 35 are respectively disposed on the front and rear sides of the pressing structure 32 .

[0050] Combined with reference Figure 3 and Figure 4 As shown, the auxiliary rollers 35 on the front and rear sides of the pressing structure 32 can, on the one hand, press the plate to make it enter the electrode system and keep it straight; on the other hand, the auxiliary rollers 35 can also be cleaning rollers, which can clean the plate before corona treatment to ensure that there is no dirt, grease or other impurities on its surface to ensure the effect and quality of the corona treatment. Specifically, cleaning the plate can improve the treatment effect, reduce the interference of impurities on the corona treatment, and make the effect of the corona treatment more stable and consistent; the surface of the clean plate can better adhere to the coating, ink or adhesive, and improve the adhesion of the coating or bonding.
