[0023] 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.

[0024] It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0025] With the rapid development of the photovoltaic industry, paper packaging is widely used to reduce friction between glass and avoid irreversible effects on component performance during the transportation of component glass. However, with the increasing popularity of intelligent mechanization, most paper packaging still relies on paper laying machines. Unwinding, as the most important part of paper laying, is mainly controlled by high-precision electrical component encoders.

[0026] In actual application, the frequent oscillation of the rocker arm connected to the encoder will cause a certain degree of damage to the encoder accuracy. After a long time, the encoder will jump and become unusable, which will cause great obstacles to production costs and production stability.

[0027] In the existing technical solution, the impact on the encoder is reduced by changing the hard connection to a spring coupling. The spring coupling has a certain shock absorption effect, which can reduce the mechanical vibration caused by unstable factors such as vibration and impact during the working process and transmit it to the encoder, thereby protecting the stable operation of the encoder. However, the shock absorption effect is not obvious, the damage rate of the encoder is still high, and the spring part of the spring coupling needs to be regularly inspected and maintained to ensure its elasticity and normal operation. The spring coupling is usually expensive, and the cost of daily inspection and maintenance is high.

[0028] Based on this, an embodiment of the present application provides a reeling device and a paper laying machine system, which improves the reeling efficiency during the paper laying process and improves the stability of the reeling device by setting a proximity switch.

[0029] Reference Figure 1-2 As shown, Figure 1 is a structural schematic diagram of an unwinding device provided in an embodiment of the present application, Figure 2 It is a schematic diagram of the structure of a mounting disk 120 provided in an embodiment of the present application.

[0030] The embodiment of the present application provides a rewinding device, including: a workbench 110; a mounting disk 120, which is arranged at the feeding end of the workbench 110, the mounting disk 120 is provided with an arc through hole 125, and a plurality of proximity switches are arranged on a side close to the arc through hole 125; a paper placing mechanism 130, which is mounted on the feeding end of the workbench 110, the paper placing mechanism 130 includes a rocker arm 131 and an expansion rod 132 which are linked together, the rocker arm 131 is embedded in the mounting disk 120 through the arc through hole 125, the rocker arm 131 is used to move in the arc through hole 125 to trigger the proximity switch, and the expansion rod 132 is used to place paper at a speed corresponding to the proximity switch.

[0031] It should be noted that the paper or coil to be unwound is placed in the paper unwinding mechanism 130 of the unwinding device. After the unwinding device is powered on, the swing rod 131 moves in the circular arc through hole 125 of the mounting plate 120. Since the swing rod 131 is linked to the gas expansion rod 132, the working state of the gas expansion rod 132 changes when the swing rod 131 moves. During the movement of the swing rod 131, the swing rod 131 can touch the proximity switch set in the circular arc through hole 125. Since different proximity switches are set with different speed values, the embodiment of the present application triggers different proximity switches through the swing rod 131 to change the paper unwinding speed of the paper unwinding mechanism 130.

[0032] Specifically, the embodiment of the present application is provided with a plurality of proximity switches on a side close to the arc through hole 125. When the control rocker arm 131 is located at different proximity switches in the arc through hole 125 of the mounting plate 120, the angle of the rocker arm 131 is sensed by the proximity switch to determine the position of the rocker arm 131, and the inflatable rod 132 is adjusted by the motor to place the paper.

[0033] In one embodiment of the present application, the paper to be unwound is placed in the paper unwinding mechanism 130 of the unwinding device. After the unwinding device is powered on and started, the number of papers or coils to be unwound is sufficient, and the swing rod 131 is moved to the proximity switch corresponding to the highest paper unwinding speed point in the arc through hole 125. At this time, the air expansion rod 132 is driven to unwind the paper at the highest speed. When the paper or coil to be unwound is about to be unwound or has been unwound, the swing rod 131 is moved to the proximity switch corresponding to the lowest paper unwinding speed point or the stop point in the arc through hole 125. At this time, the air expansion rod 132 is driven to unwind the paper at the lowest speed or not to unwind the paper.

[0034] In another embodiment of the present application, the paper to be unwound is placed in the paper unwinding mechanism 130 of the unwinding device. After the unwinding device is powered on, the swing rod 131 is moved to any position in the arc through hole 125 according to the number of unwound papers or coils. As the number of unwound papers or coils completed is changed, the position of the swing rod 131 automatically changes, and the paper unwinding speed of the pneumatic rod 132 linked to it is also changing. When the paper unwinding is completed, the swing rod 131 moves to the proximity switch corresponding to the stop point in the arc through hole 125, and controls the pneumatic rod 132 to stop running.

[0035] In some embodiments, the unwinding device also includes a paper pulling mechanism 140 mounted on the workbench 110, the paper pulling mechanism 140 includes a towing device 141 and a first driving device 142, the towing device 141 is used to pull the paper placed on the workbench 110, and the first driving device 142 is used to drive the towing device 141 to move along a preset direction.

[0036] It should be noted that after the unwinding device is powered on, the paper is placed into the feed end of the workbench 110 through the paper placing mechanism 130, and at the same time, the first driving device 142 in the paper pulling mechanism 140 drives the towing device 141 to pull the paper, thereby pulling out the paper and rolling it on the workbench 110.

[0037] In one embodiment of the present application, a motor can be used as the first driving device 142 for driving, and the dragging device 141 can be a dragging arm. After the dragging arm clamps the paper, the dragging arm is driven by the motor to move in the positive direction of the x-axis. Since one side of the paper is fixed on the dragging arm, the paper also moves with the dragging arm in the positive direction of the x-axis and is pulled out, thereby achieving the effect of pulling out the paper.

[0038] In some embodiments, the paper placing mechanism 130 includes a second driving device 133, which is respectively connected to the rocker arm 131 and the inflatable rod 132, and is used to drive the rocker arm 131 to move in the circular arc through hole 125, and is also used to drive the inflatable rod 132 to rotate.

[0039] It should be noted that a motor can be used as the second driving device 133 for driving. The second driving device 133 is connected to the rocker arm 131. According to the paper feeding speed of the paper feeding mechanism 130, the rocker arm 131 is driven to move in the circular arc through hole 125 by the second driving device 133. The proximity switch senses the position of the rocker arm 131, and the second driving device 133 drives the inflation rod 132 to rotate. The inflation rod 132 is rotated to place the paper on the feeding end of the workbench 110.

[0040] In some embodiments, two adjacent proximity switches constitute a switch interval; the proximity switch includes a limit switch 121 and a speed switch, the limit switch 121 is a switch that indicates that the rocker arm 131 has reached a preset height, and the speed switch is a switch that indicates the speed that the inflatable rod 132 needs to reach.

[0041] It should be noted that the limit switch 121 is a switch that indicates that the swing rod 131 has reached a preset height, wherein the preset height is the highest height preset by the arc through hole 125. The speed switch interval where the swing rod 131 is located is determined by the proximity switch, and the pneumatic rod 132 rotates at a speed corresponding to the switch interval. The limit switch 121 is located at the highest point of the arc through hole 125 of the mounting plate 120. When the swing rod 131 is located in the switch interval between the limit switch 121 and the adjacent speed switch, the pneumatic rod 132 does not rotate; when the swing rod 131 is located in the switch interval between two adjacent speed switches, the pneumatic rod 132 rotates at a speed corresponding to the switch interval at the switch interval, thereby achieving an effect in which the paper placing speed can be controlled.

[0042] In some embodiments, the speed switch includes a first speed control switch 122, a second speed control switch 123 and a third speed control switch 124, the limit switch 121, the first speed control switch 122, the second speed control switch 123 and the third speed control switch 124 are sequentially arranged on the mounting plate 120 along one side of the arc through hole 125, and the speeds corresponding to the first speed control switch 122, the second speed control switch 123 and the third speed control switch 124 decrease sequentially.

[0043] It should be noted that the first speed control switch 122, the second speed control switch 123 and the third speed control switch 124 are arranged in sequence in the arc through hole 125 of the mounting plate 120, wherein the setting heights of the speed control switches decrease or increase in sequence. By setting different speed control switches, the operator can select a suitable speed according to specific work requirements, thereby obtaining optimal performance and effects under different working conditions.

[0044] Reference Figure 2 As shown, in one embodiment of the present application, the limit switch CL, the first speed control switch H, the second speed control switch L and the third speed control switch XZ are sequentially arranged on the mounting plate along one side of the circular arc through hole, wherein the limit switch CL is used to determine that the rocker arm has reached the response height, triggering the first speed control switch H to increase the paper feeding speed, triggering the second speed control switch L to slow down the paper feeding speed, triggering the third speed control switch XZ to reduce the paper feeding speed to the minimum or stop running.

[0045] In another embodiment of the present application, after the paper to be unwound is placed in the paper unwinding mechanism 130 of the unwinding device, the rocker arm 131 is set between the first speed control switch 122 and the second speed control switch 123. When the unwinding of the paper is about to be completed, the rocker arm 131 is set between the second speed control switch 123 and the third speed control switch 124.

[0046] In another embodiment of the present application, after placing the paper or coil to be unwound in the paper unwinding mechanism 130 of the unwinding device, the swing rod 131 is moved to any position in the arc through hole 125. As the amount of unwound paper increases, the swing rod 131 slides along the arc in the arc through hole 125 to change the paper unwinding speed. When the unwinding is completed, the swing rod 131 is located at the end of the arc through hole 125 and the paper unwinding stops.

[0047] In some embodiments, the first speed control switch 122 and the second speed control switch 123 constitute a first speed control interval, the second speed control switch 123 and the third speed control switch 124 constitute a second speed control interval, and the unwinding speed of the expansion rod 132 in the first speed control interval is lower than the unwinding speed of the expansion rod 132 in the second speed control interval.

[0048] It should be noted that the first speed regulating switch 122 and the second speed regulating switch 123 form a first speed regulating interval, while the second speed regulating switch 123 and the third speed regulating switch 124 form a second speed regulating interval. This setting can provide operators with more speed options and is divided into different intervals, which is convenient for operating and adjusting the equipment.

[0049] In one embodiment of the present application, after the paper or coil to be unwound is placed in the paper unwinding mechanism 130 of the unwinding device, the swing rod 131 is set to be located in the first speed regulation range. When the unwinding of the paper is about to be completed, the swing rod 131 is adjusted to be located in the second speed regulation range.

[0050] In another embodiment of the present application, after placing the paper or coil to be unwound in the paper unwinding mechanism 130 of the unwinding device, the swing rod 131 is moved to a certain interval in the circular arc through hole 125 according to the number of paper or coils to be unwound. As the number of unwound papers increases, the swing rod 131 continues to slide slowly downward along the arc in the circular arc through hole 125 to control the paper unwinding speed. When the unwinding of the paper is completed, the swing rod 131 is located at the lowest end of the circular arc through hole 125, and the unwinding of the paper is stopped.

[0051] In some embodiments, the dragging device 141 includes a dragging arm and a plurality of clamping claws, the clamping claws are arranged on the dragging arm at preset intervals, and the clamping claws are used to clamp the paper placed on the workbench 110 .

[0052] It should be noted that clamps are provided at certain intervals on the drag arm, and the paper placed on the workbench 110 is clamped by the clamps. When the drag arm moves in the positive direction of the x-axis, the paper is dragged so that the paper moves with it, thereby achieving the effect of pulling out the paper.

[0053] In some embodiments, the paper placing mechanism 130 also includes a pressing device 150 mounted on the workbench 110, the pressing device 150 includes a pressing plate 151, a pressing roller 152 and a third driving device 153, the third driving device 153 is connected to the pressing roller 152 to drive the pressing roller 152 to push the paper, and the pressing roller 152 cooperates with the pressing plate 151 to flatten the paper.

[0054] It should be noted that the third driving device 153 can be driven by a motor. The paper is placed at the feeding end of the workbench 110 through the paper placing mechanism 130, and is pulled out by the paper pulling mechanism 140 to unfold on the workbench 110. When the paper passes through the pressing plate 151, the pressing roller 152 is driven by the motor to rotate. The pressing roller 152 and the pressing plate 151 cooperate with each other to flatten the paper, so that the paper is in a flattened state without wrinkles, which is convenient for subsequent paper winding operations. At the same time, the pressing roller 152 also pushes the paper to move in the positive direction of the x-axis during the rotation process.

[0055] In some embodiments, the paper placing mechanism 130 further includes a cutting device mounted on the workbench 110 , and the cutting device is used to cut the paper placed on the workbench 110 .

[0056] It should be noted that after the inflation rod 132 rotates to place the paper at the feeding end, the cutting device cuts the paper into a preset paper specification; for example, when the roll product reaches the maximum roll limit, the cutting device cuts the paper, and then continues to unwind to form the next roll product. The cutting device ensures the uniform specifications of the paper and realizes the effect of automatically switching the paper balls.

[0057] In one embodiment of the present application, during the paper placing and rolling process, the paper pulling mechanism 140 pulls out the cut paper, and at the same time the air expansion rod 132 places new paper at the feed end, and the new paper is cut into preset paper specifications by the cutting device.

[0058] In another embodiment of the present application, when the paper ball is about to reach the maximum paper rolling limit, the paper is cut by a cutting device, and the paper pulling mechanism 140 pulls out the remaining paper for paper rolling. After the paper rolling is completed, the cut paper is clamped and pulled out to form a new paper ball.

[0059] An embodiment of the present application also provides a paper laying machine system, including the unwinding device as described above.
