Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-adhesive label processing technology, and in particular to a roll unwinding structure for self-adhesive label processing to prevent deviation. Background Technology
[0002] In the production and processing of self-adhesive labels, the roll unwinding process is a key link connecting raw materials with subsequent processing. Its stability directly determines the final product quality of the self-adhesive labels. This process requires the roll of self-adhesive substrate (such as adhesive paper, PET film substrate, etc.) to be released smoothly and accurately to subsequent processing equipment such as printing, die-cutting, and lamination to ensure the consistency of the substrate conveying path.
[0003] Existing unwinding devices typically achieve static positioning using guide rollers with fixed spacing, which can only provide initial guidance for the roll material and cannot cope with dynamic offsets during the unwinding process. When the roll material shifts in width due to factors such as unwinding tension fluctuations or equipment vibrations, the static guiding structure cannot be adjusted in real time, causing the roll material conveying path to deviate from the reference, which in turn leads to subsequent issues such as misalignment of printed patterns and die-cutting size deviations. Furthermore, existing unwinding devices are usually not convenient for quickly adjusting the unwinding tension according to different types of roll material, and typically require manual replacement of counterweights or adjusting bolts, which is cumbersome and has low adjustment accuracy.
[0004] To address this, a roll unwinding structure for self-adhesive label processing is proposed to prevent misalignment. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 The present invention provides the following technical solution:
[0026] A roll unwinding and anti-deviation structure for self-adhesive label processing includes a base 1, and an anti-deviation mechanism 2 and an unwinding mechanism 3 are provided on the top of the base 1.
[0027] The anti-deviation mechanism 2 includes two upright plates 21, which are fixedly connected to the two sides of the top rear side of the base 1. Electric telescopic rods 22 are fixedly connected to the top of the opposite side of the two upright plates 21. The output rods of the two electric telescopic rods 22 pass through the two upright plates 21 and are fixedly connected to the fixing blocks 23. Position sensors 24 are fixedly connected to the bottom of the two fixing blocks 23. The bottom of the inner wall of the two upright plates 21 is rotatably connected to the correction screw 25 through bearings. The surface of the correction screw 25 is fitted with a correction moving block 26. A forward and reverse motor 27 that works with the correction screw 25 is fixedly connected to the bottom of one side of one of the upright plates 21. The output shaft of the forward and reverse motor 27 is fixedly connected to one end of the correction screw 25.
[0028] In this embodiment: by setting up a base 1, an anti-deviation mechanism 2, and an unwinding mechanism 3, the base 1 provides a supporting foundation for the entire device during use. The anti-deviation mechanism 2 provides dynamic anti-deviation during the unwinding process, monitoring the edge position of the roll material in real time and automatically correcting it, effectively preventing the roll material from shifting along the width direction during unwinding, ensuring the accuracy of subsequent printing, die-cutting, and other processing steps, thereby reducing material waste and product quality issues caused by deviation. The unwinding mechanism 3 enables stable unwinding of self-adhesive roll material and allows for convenient and quick adjustment of the unwinding tension according to different types of roll material, providing convenience for operators.
[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the unwinding mechanism 3 includes a movable seat 31. The rear side of the movable seat 31 is fixedly connected to the front side of the correction moving block 26. A fixed plate 32 is fixedly connected to the left side of the top of the movable seat 31. An air shaft 33 is rotatably connected to the top of the front side of the inner wall of the fixed plate 32 through a bearing. An unwinding motor 34 that works with the air shaft 33 is fixedly connected to the top of the front left side of the fixed plate 32. The output shaft of the unwinding motor 34 is fixedly connected to one end of the air shaft 33.
[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, electric lifting rods 35 are fixedly connected to both sides of the top of the movable seat 31. The top of the output rods of the two electric lifting rods 35 are rotatably connected to tension rollers 36 through bearing seats. The top of the right rear side of the fixed plate 32 is rotatably connected to guide rollers 37 through bearing seats.
[0031] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, guide rails 38 and guide slide blocks 39 are provided on the front and rear sides of the bottom of the movable base 31. The guide slide block 39 is slidably connected to the surface of the guide rail 38. The bottom of the guide rail 38 is fixedly connected to the top of the base 1, and the top of the guide slide block 39 is fixedly connected to the bottom of the movable base 31.
[0032] In this embodiment: by setting up a movable seat 31, a fixed plate 32, an air shaft 33, an unwinding motor 34, an electric lifting rod 35, a tension roller 36, a guide roller 37, a guide slide rail 38, and a guide slide block 39, in use, the self-adhesive roll is placed on the air shaft 33 and its position is adjusted. Then, the air shaft 33 is inflated, so that the air shaft 33 can stably fix the position of the roll through air expansion. Then, the free end of the roll passes through the bottom of the tension roller 36, then through the top of the guide roller 37, and finally into the subsequent processing equipment. During unwinding, the unwinding motor 34 can be started, so that the output shaft of the unwinding motor 34 drives the air shaft 33 to rotate, and the air shaft 33 will drive... The coil rotates, allowing for unwinding. Tension roller 36 provides unwinding tension, and guide roller 37 guides and transmits the coil. When unwinding tension needs adjustment, simply activate the two electric lifting rods 35, extending or retracting their output rods to move tension roller 36 up and down. This allows for convenient and rapid adjustment of unwinding tension based on different types of coils, providing convenience for operators. Guide slide 39 and guide rail 38 guide and limit the movement of the movable seat 31, enabling stable left and right movement during correction.
[0033] Specifically, such as Figure 4 As shown, the top of the two upright plates 21 on opposite sides is provided with through holes 4 for use with electric telescopic rods 22, and the output rod surface of the electric telescopic rod 22 is slidably connected to the inner wall of the through holes 4.
[0034] Specifically, such as Figure 4 As shown, the inside of the correction moving block 26 is provided with a threaded hole 5 that works with the correction screw 25, and the inner wall of the threaded hole 5 is connected to the surface of the correction screw 25 by threads.
[0035] In this embodiment: by providing through hole 4, the output rod of electric telescopic rod 22 can pass through vertical plate 21 for telescopic output; by providing threaded hole 5, when the correction screw 25 rotates, the correction moving block 26 can drive the moving base 1 to move through the action of the thread.
[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a PLC controller 6 is provided on the rear side of the top right side of the base 1, which works in conjunction with the anti-deviation mechanism 2 and the unwinding mechanism 3. The PLC controller 6 is electrically connected to the anti-deviation mechanism 2 and the unwinding mechanism 3.
[0037] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a support frame 7 is fixedly connected to the bottom of the PLC controller 6, and the bottom of the support frame 7 is fixedly connected to the rear side of the top right side of the base 1.
[0038] In this embodiment: by setting up a PLC controller 6, the anti-deviation mechanism 2 and the unwinding mechanism 3 can be controlled to perform stable unwinding, anti-deviation detection and automatic deviation correction. By setting up a support frame 7, the PLC controller 6 can be supported and fixed.
[0039] Working principle: In use, first, the self-adhesive roll is placed on the air shaft 33 and its position is adjusted. Then, the air shaft 33 is inflated, allowing it to stably fix the position of the roll. Next, the free end of the roll passes through the bottom of the tension roller 36, then through the top of the guide roller 37, and finally into the subsequent processing equipment. During unwinding, the unwinding motor 34 is started by the PLC controller 6, causing its output shaft to drive the air shaft 33 to rotate. The air shaft 33 then rotates the roll, thus... During the unwinding process, tension roller 36 provides unwinding tension, and guide roller 37 guides and transfers the material. When adjusting the unwinding tension, the PLC controller 6 activates two electric lifting rods 35, causing their output rods to extend or retract synchronously, thus moving the tension roller 36 up and down. This allows for convenient and quick adjustment of the unwinding tension based on different types of rolls, providing convenience for operators. Simultaneously, the PLC controller 6 activates two electric telescopic rods 22, causing their output rods to extend or retract, which in turn moves the two fixed blocks 23 and position sensors 24 closer or further apart, adjusting the distance between the two position sensors 24 to match the roll width. The two position sensors 24 can detect the roll edge position in real time and transmit the detection signal to the PLC controller 6. When the roll deviates, the PLC controller 6 automatically activates the forward and reverse motor 27, causing its output shaft to drive the correction screw 25 to rotate in either direction. By rotating the correction screw 25 in the forward or reverse direction, the correction moving block 26 will move to the left or right under the action of the thread. The correction moving block 26 will drive the moving seat 31 to slide to the left or right along the guide slide rail 38 through the guide slide 39, thereby driving the entire unwinding mechanism 3 to adjust its position until the roll material returns to the reference position. This can achieve the effect of dynamic correction, effectively preventing the roll material from shifting along the width direction during unwinding, ensuring the accuracy of subsequent printing, die-cutting and other processing steps, thereby reducing material waste and product quality problems caused by deviation.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
