TECHNICAL FIELD

[0001] The utility model relates to a film device for sheet metal processing technical field especially relates to a film device for sheet metal processing. BACKGROUND

[0002] Sheet metal processing is a kind of comprehensive cold working process for metal sheet, including shearing, punching / cutting / compounding, folding, riveting, splicing, forming (such as automobile body) and other operations, in the sheet metal processing, in order to protect the surface of plate from scratching, corrosion and meet the requirements of some subsequent processing (such as painting), it is often necessary to film on the surface of sheet metal.

[0003] At present, in many film processes of sheet metal processing, when processing the film between adjacent workpieces, artificial cutting is often used, and the operator uses a tool (such as a knife) to cut off the film between adjacent workpieces, since the sheet metal workpieces on the production line are continuously advancing, continuous manual cutting action not only makes the workers easy to fatigue, but also may cause waste of film or damage to the surface of workpiece due to operation error. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the shortcomings in the prior art and provides a film device for sheet metal processing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a film device for sheet metal processing, including conveying table, the conveying table is rotatably connected with a plurality of conveying rollers through bearing, the conveying table is fixedly connected with mounting bracket, the conveying table is rotatably connected with lower film roller through bearing, the conveying table is fixedly connected with two fixed supports, the fixed support is slidably connected with adjusting block, the adjusting block is fixedly connected with first motor, the two adjusting blocks are rotatably connected with upper film roller through bearing, the upper film roller is rotated by first motor drive, the fixed support is fixedly connected with first cylinder, the piston rod of first cylinder is fixedly connected with an adjusting block, the conveying table is provided with cutting structure, the cutting structure is mainly composed of gantry, the gantry is fixedly connected on the conveying table, the gantry is fixedly connected with second cylinder, the piston rod of second cylinder is fixedly connected with mounting plate, the mounting plate is fixedly connected with cutting knife, the conveying table is fixedly connected with guide plate, the conveying table is fixedly connected with fixed plate.

[0006] The aforementioned components achieve the following effects: The conveyor rollers, driven by a motor, place the sheet metal parts on a conveyor table. Several conveyor rollers propel the sheet metal parts forward. A film-coating roll is mounted on the mounting frame. When the sheet metal part passes between the lower and upper film-coating rollers, the first motor is activated, driving the upper film-coating roller to rotate and apply the protective film to the sheet metal part. The distance between the lower and upper film-coating rollers can be adjusted according to the thickness of the sheet metal part by moving the adjusting block up and down via the activation of the first cylinder. An ultrasonic sensor is installed on the gantry frame to detect the preset edge of the sheet metal workpiece. When the ultrasonic sensor... When the edge of the workpiece is detected, a positioning signal is generated. This signal is transmitted to the PLC controller, which controls the second cylinder to start based on the positioning signal. The piston rod of the gantry moves the mounting plate down rapidly, causing the cutting blade to cut the protective film. The sheet metal workpiece after the film is cut slides down through the guide plate. A collection box is placed below the guide plate to collect the sheet metal workpiece. This avoids the continuous manual cutting action that is common on the production line, where sheet metal workpieces move forward one by one. This not only makes the workers prone to fatigue but also may cause waste of film or damage to the surface of the workpiece due to operational errors.

[0007] Preferably, the inner walls on both sides of the gantry are respectively provided with sliding grooves, and a slider is slidably connected in the sliding groove, and the slider is fixedly connected to the mounting plate.

[0008] The effect achieved by the above components is that the two sliders slide within the groove, making the movement of the mounting plate more stable and thus improving the cutting accuracy.

[0009] Preferably, a rotating shaft is rotatably connected to the mounting plate via a bearing, a telescopic plate is fixedly connected to the rotating shaft, and a pressure roller is rotatably connected to the two telescopic plates via bearings.

[0010] The effect achieved by the above components is as follows: when the mounting plate descends, it will drive the telescopic plate to descend, so that the pressure roller contacts the surface of the sheet metal part. As the mounting plate descends, the pressure roller rolls and presses on the sheet metal part, limiting its movement and improving the cutting effect.

[0011] Preferably, two limiting blocks are fixedly connected to the mounting plate, and a spring is fixedly connected to the sliding cavity of the telescopic plate.

[0012] The effects achieved by the above components are as follows: the limiting block can limit the telescopic plate, prevent the pressure roller from contacting the cutting blade, and when the pressure roller presses against the sheet metal part, the spring is in a contracted state, so the spring rebound force acts on the pressure roller, making the limiting more stable.

[0013] Preferably, the conveyor platform is provided with a limiting structure, which is mainly composed of two rectangular plates. Both rectangular plates are fixedly connected to the conveyor platform, and three round rods are slidably inserted into the rectangular plates. The limiting plate is fixedly connected to the three round rods together.

[0014] The effect achieved by the above components is that the sliding rod drives the two limiting plates to move closer to each other, clamping and limiting the two sides of the sheet metal workpiece, so that the sheet metal workpiece is always in the middle position, improving the coating effect.

[0015] Preferably, a plurality of rollers are rotatably connected to the limiting plate, and one end of the three round rods is fixedly connected to a connecting plate.

[0016] The effect achieved by the above components is that the rollers can reduce the friction between the limiting plate and the sheet metal workpiece, preventing the sheet metal from being affected in its movement on the conveyor rollers.

[0017] Preferably, two fixing blocks are fixedly connected to the limiting plate, and a bidirectional screw is rotatably connected to the conveyor platform via bearings. The two sections of the bidirectional screw have opposite thread directions. The bidirectional screw is threadedly connected to the two fixing blocks. A second motor is fixedly connected to the conveyor platform, and the bidirectional screw is driven to rotate by the second motor.

[0018] The effect achieved by the above components is as follows: the output end of the second motor is connected to the bidirectional screw through a reducer and a coupling. When the second motor is started, it drives the bidirectional screw to rotate, causing the two limit plates to slide synchronously in opposite directions, making the operation more convenient and the limit more stable.

[0019] Preferably, a limiting rod is fixedly connected to the conveyor platform, and the limiting rod is slidably connected to two fixed blocks.

[0020] The effect achieved by the above components is that the limiting plate slides at the upper limit of the limiting rod, making the sliding process of the limiting plate more stable.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a cutting structure, the conveyor rollers are driven by a motor to place the sheet metal parts on the conveyor table. Several conveyor rollers drive the sheet metal parts forward. A film-coating roll is installed on the mounting frame. When the sheet metal parts pass between the lower and upper film-coating rollers, the first motor is started. The first motor drives the upper film-coating roller to rotate, covering the sheet metal parts with a protective film. The distance between the lower and upper film-coating rollers can be adjusted according to the thickness of the sheet metal parts by starting the first cylinder to move the adjusting block up and down. An ultrasonic sensor is installed on the gantry frame to detect the sheet metal work. The ultrasonic sensor detects the edge of the workpiece at a preset edge and generates a positioning signal. This signal is transmitted to the PLC controller, which then controls the second cylinder to start. The piston rod of the gantry moves the mounting plate down rapidly, causing the cutting blade to cut the protective film. The sheet metal workpiece after the film is cut slides down through a guide plate, and a collection box is placed below the guide plate to collect the sheet metal workpiece. This avoids the continuous manual cutting action that occurs when sheet metal workpieces on the production line move forward one by one, which not only easily causes fatigue for the workers but also may lead to waste of film or damage to the surface of the workpiece due to operational errors.

[0027] Example 1, such as Figure 1 and Figure 2 As shown, a sheet metal processing coating device includes a conveyor table 1, a plurality of conveyor rollers 2 rotatably connected to the conveyor table 1 via bearings, a mounting frame 3 fixedly connected to the conveyor table 1, a lower coating roller 5 rotatably connected to the conveyor table 1 via bearings, two fixed frames 4 fixedly connected to the conveyor table 1, an adjusting block 7 slidably connected to the fixed frame 4, a first motor 6 fixedly connected to the adjusting block 7, an upper coating roller 11 rotatably connected to the two adjusting blocks 7 via bearings, the upper coating roller 11 being driven to rotate by the first motor 6, a first cylinder 10 fixedly connected to one of the fixed frames 4, and the piston rod of the first cylinder 10 being fixedly connected to one of the adjusting blocks 7.

[0028] Reference Figure 2 and Figure 3A cutting structure 8 is installed on the conveyor table 1. The cutting structure 8 mainly consists of a gantry frame 81, which is fixedly connected to the conveyor table 1. A second cylinder 82 is fixedly connected to the gantry frame 81. A mounting plate 83 is fixedly connected to the piston rod of the second cylinder 82. A cutting blade 84 is fixedly connected to the mounting plate 83. A guide plate 88 and a fixing plate 85 are fixedly connected to the conveyor table 1. The conveyor rollers 2 are driven by a motor to place the sheet metal parts on the conveyor table 1. Several conveyor rollers 2 drive the sheet metal parts forward. A film-coated roll is installed on the mounting frame 3. When the sheet metal parts pass between the lower film-coating roller 5 and the upper film-coating roller 11, the first motor 6 is started. The first motor 6 drives the upper film-coating roll. Roller 11 rotates, applying a protective film to the sheet metal part. The first cylinder 10 can be activated to move the adjusting block 7 up and down, adjusting the distance between the lower and upper coating rollers 5 and 11 according to the thickness of the sheet metal part. An ultrasonic sensor is installed on the gantry 81 to detect the preset edge of the sheet metal workpiece. When the ultrasonic sensor detects the edge, it generates a positioning signal, which is transmitted to the PLC controller. The PLC controller then activates the second cylinder 82 based on the positioning signal. The piston rod of the gantry 81 causes the mounting plate 83 to descend rapidly, causing the cutting blade 84 to cut the protective film. The cut sheet metal workpiece slides down the guide plate 88 and is placed below the guide plate 88 for collection. The box collects sheet metal parts, thus avoiding the continuous manual cutting action caused by the sheet metal parts moving forward one by one on the production line. This not only easily leads to worker fatigue but also may cause waste of film or damage to the surface of the workpiece due to operational errors. The inner walls of both sides of the gantry 81 are respectively provided with sliding grooves 86, in which sliders 87 are slidably connected. The sliders 87 are fixedly connected to the mounting plate 83. The two sliders 87 slide within the sliding grooves 86, making the movement of the mounting plate 83 more stable and thus improving the cutting accuracy. A rotating shaft 89 is rotatably connected to the mounting plate 83 via bearings. Telescopic plates 810 are fixedly connected to the rotating shaft 89. The two telescopic plates 810 are connected via... The bearing is connected to the pressure roller 811 for rotation. When the mounting plate 83 descends, it will drive the telescopic plate 810 to descend, so that the pressure roller 811 contacts the surface of the sheet metal part. As the mounting plate 83 descends, the pressure roller 811 rolls and presses on the sheet metal part, limiting its movement and improving the cutting effect. Two limiting blocks 812 are fixedly connected to the mounting plate 83. A spring 813 is fixedly connected in the sliding cavity of the telescopic plate 810. The limiting blocks 812 can limit the telescopic plate 810, preventing the pressure roller 811 from contacting the cutting blade 84. When the pressure roller 811 presses on the sheet metal part, the spring 813 is in a contracted state. Therefore, the rebound force of the spring 813 acts on the pressure roller 811, making the limiting more stable.

[0029] Reference Figure 4A limiting structure 9 is provided on the conveyor table 1. The limiting structure 9 mainly consists of two rectangular plates 91, both of which are fixedly connected to the conveyor table 1. Three round rods 92 are slidably inserted into the rectangular plates 91, and a limiting plate 93 is fixedly connected to the three round rods 92. The sliding round rods 92 drive the two limiting plates 93 to move closer to each other, clamping and limiting the two sides of the sheet metal workpiece, so that the sheet metal workpiece is always in the center position, improving the coating effect. Several rollers 94 are rotatably connected to the limiting plate 93. One end of the three round rods 92 is fixedly connected to a connecting plate 95. The rollers 94 can reduce the friction between the limiting plate 93 and the sheet metal workpiece, preventing it from affecting the sheet metal's movement on the conveyor roller 2. Two fixing blocks 9 are fixedly connected to the limiting plate 93. 6. A bidirectional screw 97 is rotatably connected to the conveyor table 1 via bearings. The two sections of the bidirectional screw 97 have opposite thread directions. The bidirectional screw 97 is threadedly connected to two fixed blocks 96. A second motor 98 is fixedly connected to the conveyor table 1. The bidirectional screw 97 is driven to rotate by the second motor 98. The output end of the second motor 98 is connected to the bidirectional screw 97 via a reducer and a coupling. When the second motor 98 is started, it drives the bidirectional screw 97 to rotate, causing the two limit plates 93 to slide synchronously in opposite directions, making the operation more convenient and the limit more stable. A limit rod 99 is fixedly connected to the conveyor table 1. The limit rod 99 is slidably connected to the two fixed blocks 96. The limit plate 93 slides at the limit rod 99, making the sliding process of the limit plate 93 more stable.

[0030] Working principle: The conveyor rollers 2, driven by a motor, place the sheet metal parts on the conveyor table 1. Several conveyor rollers 2 drive the sheet metal parts forward. A film-coating roll is installed on the mounting frame 3. When the sheet metal parts pass between the lower film-coating roller 5 and the upper film-coating roller 11, the first motor 6 is started. The first motor 6 drives the upper film-coating roller 11 to rotate, applying the protective film to the sheet metal parts. The distance between the lower film-coating roller 5 and the upper film-coating roller 11 can be adjusted according to the thickness of the sheet metal parts by starting the first cylinder 10 to move the adjusting block 7 up and down. An ultrasonic sensor is installed on the gantry frame 81 to detect the preset edge of the sheet metal workpiece. When the ultrasonic sensor detects the workpiece… When the edge is reached, a positioning signal is generated, which is transmitted to the PLC controller. Based on the positioning signal, the PLC controller activates the second cylinder 82. The piston rod of the gantry 81 drives the mounting plate 83 to descend rapidly, causing the cutting blade 84 to cut the protective film. The sheet metal workpiece after cutting the film slides down through the guide plate 88. A collection box is placed below the guide plate 88 to collect the sheet metal workpiece. This avoids the continuous manual cutting action that occurs when sheet metal workpieces move forward one by one on the production line. This not only easily causes worker fatigue but also may lead to wasted film or damage to the workpiece surface due to operational errors. The two sliders 87 are in the chute 8. The six-position sliding limit makes the movement of the mounting plate 83 more stable, thereby improving the cutting accuracy. When the mounting plate 83 descends, it will drive the telescopic plate 810 to descend, so that the pressure roller 811 contacts the surface of the sheet metal part. As the mounting plate 83 descends, the pressure roller 811 rolls and presses on the sheet metal part, limiting its movement and improving the cutting effect. The limiting block 812 can limit the telescopic plate 810, preventing the pressure roller 811 from contacting the cutting blade 84. When the pressure roller 811 presses against the sheet metal part, the spring 813 is in a contracted state. Therefore, the rebound force of the spring 813 acts on the pressure roller 811, making the limiting more stable. Sliding rod 92 The two limiting plates 93 are brought closer together to clamp and limit the two sides of the sheet metal workpiece, ensuring that the sheet metal workpiece is always in the center position, thus improving the coating effect. The roller 94 can reduce the friction between the limiting plates 93 and the sheet metal workpiece, preventing it from affecting the sheet metal's movement on the conveyor roller 2. The output end of the second motor 98 is connected to the bidirectional screw 97 through a reducer and a connecting shaft. When the second motor 98 is started, it drives the bidirectional screw 97 to rotate, causing the two limiting plates 93 to slide synchronously in opposite directions, making the operation more convenient and the limiting more stable. The limiting plates 93 slide at the upper limit of the limiting rod 99, making the sliding process of the limiting plates 93 more stable.
