DETAILED DESCRIPTION

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] See also Figure 1 to Figure 5 As shown, a flattening device for processing plastic film comprises a workbench 1 and a flattening assembly and a wrinkle removal assembly arranged in sequence on the workbench 1. The workbench 1 is placed on the ground to fix the entire flattening device. The flattening assembly comprises a main board 2, a roller 3 and a blowing assembly 4. The main board 2 is vertically mounted at one end of the workbench 1. The rollers 3 are mounted on both sides of the main board 2 and the blowing assembly 4 is arranged in the center of the main board 2. The blowing assembly comprises a first fan 4a, a second fan 4b and a third fan 4c. The three fans are all mounted on the workbench 1 at the back of the main board 2 and are perpendicular to the ground. The first fan 4a, the second fan 4b and the third fan 4c are arranged in rows on the workbench 1. The middle row of fans faces the back of the main board 2. The outer two rows of fans form an angle with the middle row of fans in a direction away from the back of the main board 2.

[0030] When the plastic film 9 passes through the main board 2 from bottom to top, three motors blow up the plastic film 9 on the main board 2 in a diffuse manner from different directions. The plastic film 9 begins to unfold initially under the action of wind force and its own gravity. At the same time, the roller 3 on the main board 2 limits the floating plastic film 9.

[0031] See also Figure 1 to Figure 5 As shown, the roller shaft 3 includes a steering drive device, a rotation drive device and a guide pattern 3c; the roller shaft is installed on the main board 2 through a positioning rod 3a and a first sleeve 3b, the steering drive device is arranged on the main board 2 and connected to the first sleeve 3b, the rotation drive device is arranged inside the main board 2 and connected to the roller shaft 3, and the guide pattern 3c is arranged outside the roller shaft 3;

[0032] The steering drive device enables the roller 3 to fit the floating plastic film 9 on the main board 2 at different angles, thereby amplifying the roller 3's ability to unfold the plastic film 9. The roller 3 can be rotated by the rotation drive device. At this time, the roller 3 rotates and turns to further unfold the plastic film 9. During rotation, the guide lines 3c form a certain tension to assist in unfolding the plastic film 9.

[0033] See also Figure 1 to Figure 5 As shown, the blowing assembly 4 also includes an air outlet 4d, and a plurality of air outlets 4d are arranged, evenly distributed in the center of the main board 2 corresponding to the positions of the three fans; the size of the air outlet 4d should be larger than the size of the fans in the three fans to ensure that the wind force of the fan can fully act on the plastic film 9.

[0034] See also Figure 1 to Figure 5As shown, the wrinkle removal assembly includes a material pressing assembly 5, a detection assembly 6 and a correction assembly; the material pressing assembly 5 is installed on the top of the main board 2, the detection assembly 6 is installed flatly on the top of the workbench 1 at one end close to the main board, and the correction assembly is installed flatly on the top of the workbench 1 at one end away from the main board 2;

[0035] After the plastic film 9 is unfolded by the unfolding component, the floating plastic film 9 needs to be flattened and rolled up by the pressing component 5, and then the detection component 6 is used to check whether there are wrinkles and the specific location of the wrinkles, and finally the wrinkles are processed by the correction component.

[0036] See also Figure 1 to Figure 5 As shown, the pressing assembly 5 includes a positioning frame 5a, a pressing roller 5b and a second sleeve 5c; the positioning frame 5a is fixed to the top of the main board 2, the second sleeve 5c is connected to the positioning frame 5a, and the pressing roller 5b is rotatably connected to the second sleeve 5c;

[0037] A spring is arranged between the second sleeve 5c and the positioning frame 5a, and the spring is used to reduce the wear of the pressing assembly on the plastic film 9. Through the cross-rolling of multiple groups of pressing rollers 5b, the plastic film 9 is transformed from a floating and unfolded state on the main board 2 to a compacted state and reaches the top of the workbench 1 for subsequent processing.

[0038] See also Figure 1 to Figure 5 As shown, the detection assembly 6 includes a sensor 6a and a lifting device 6b; the transmitter and the receiver of the sensor 6a are respectively installed on both sides of the workbench 1, perpendicular to the movement direction of the plastic film 9, and the lifting device 6b is composed of screws and nuts, and the screws pass through the transmitter of the sensor, and the alarm is installed above the receiver;

[0039] Sensor 6a is used to detect whether there are wrinkles on the plastic film 9 after rolling. The height of the transmitter of sensor 6a should be higher than the thickness of the plastic film 9. When wrinkles appear, the thickness of the wrinkles is higher than the normal thickness. The signal of the transmitter is blocked by the wrinkles, and the signal received by the sensor receiver disappears, and is transmitted to the controller. The controller drives the alarm 6c to issue a warning.

[0040] See also Figures 1 to 8 As shown, the correction component includes a movable bar 7 and a wrinkle removal component 8; the movable bar 7 is slidably connected to a guide rail on the workbench 1 away from the main board 2, and the wrinkle removal component 8 is slidably connected to the guide rail on the movable bar 7;

[0041] Pulleys are respectively arranged between the movable bar 7 and the workbench 1, and between the wrinkle removal component 8 and the movable bar 7 to reduce the wear of the sliding connection. The movable bar 7 can move freely in the moving direction of the plastic film 9 on the workbench 1, and the wrinkle removal component 8 can move freely on the movable bar 7 perpendicular to the moving direction of the plastic film 9, that is, the wrinkle removal component 8 can reach any position of the plastic film 9. When wrinkles appear on the plastic film 9, the component can move to the wrinkle position by displacement.

[0042] See also Figure 7-8 As shown, the wrinkle removal assembly includes a movable block 8a, a squeeze rod 8b and a roller 8c; the movable block 8a is slidably connected to the movable bar 7 through a pulley and a guide rail, a squeeze rod 8b is arranged in the center of the movable block 8a, and a roller 8c is arranged at the bottom of the squeeze rod 8b;

[0043] A spring is provided between the squeezing rod 8b and the movable block 8a to ensure that the squeezing rod 8b can automatically reset after completing the work. When removing wrinkles, the staff presses the squeezing rod 8b, and the roller 8c at the bottom of the squeezing rod 8b contacts the wrinkles to start removing the wrinkles.
