Description

Technical Field

[0001] This utility model relates to the technical field of sticker adhesive processing equipment, specifically an adjustable tensioning device for sticker adhesive processing. Background Technology

[0002] Maintaining stable and adjustable material conveying tension is a crucial process in the processing (such as printing, coating, slitting, and die-cutting) and continuous application of roll materials like stickers, labels, and tapes. The performance of the tensioning device directly affects product processing quality, production efficiency, and scrap rate.

[0003] Currently, the tensioning devices commonly used in the industry mainly suffer from the following technical problems:

[0004] (1) Many traditional devices use tension rollers or counterweights in fixed positions to provide tension, resulting in static or only coarsely adjustable tension values. They cannot respond to the slight changes in material tightness caused by changes in material roll diameter, fluctuations in conveying speed, or slight asynchrony of equipment during the production process. This can easily lead to material loosening, wrinkling, or excessive stretching and deformation during the conveying process, which seriously affects the accuracy of die-cutting positioning such as printing and generates a large number of waste products.

[0005] (2) When it is necessary to adjust the tension force according to different material properties (such as thickness, ductility) or process requirements, the existing equipment often requires manual adjustment of bolts, movement of counterweights or replacement of parts by tools. This method is not only time-consuming and labor-intensive, affecting the production rhythm, but also difficult to achieve effective and rapid online fine adjustment, which cannot meet the requirements of modern production lines for flexibility and efficiency.

[0006] (3) Tensioning is usually separated from cleaning, dust removal and other processes, requiring independent equipment and additional space layout, which increases equipment cost and floor space, and may also introduce new tension instability factors when the material passes through multiple independent workstations due to the long path.

[0007] Therefore, it is necessary to develop an adjustable tensioning device that can automatically adapt to changes in material tension, achieve rapid adjustment, integrate auxiliary functions, and operate stably and reliably. Utility Model Content

[0008] The main purpose of this application is to provide an adjustable tensioning device for sticker adhesive processing, which aims to solve the above-mentioned technical problems.

[0009] This application provides the following technical solution: an adjustable tensioning device for processing sticker adhesive, including a conveying component, the conveying component including two sets of symmetrically arranged stabilizing mechanisms that provide support, and a transmission mechanism for conveying the sticker adhesive layer is installed between the two sets of stabilizing mechanisms.

[0010] An adjustment component is installed on the conveying assembly. The adjustment component includes two sets of symmetrically arranged swing arm mechanisms that adaptively adjust the tension. A pressing mechanism that adaptively presses the adhesive layer of the sticker is installed between the two sets of swing arm mechanisms.

[0011] One end of the conveying component is equipped with a drive component, which includes a drive motor that provides driving force and is connected to a linkage mechanism for controlling the synchronous operation of the transmission mechanism and the pressing mechanism.

[0012] Preferably, each set of stabilizing mechanisms includes a triangular plate, with a stabilizing sleeve fixed at one corner of the triangular plate, and connecting arc-shaped grooves opened at the other two corners.

[0013] Preferably, the transmission mechanism includes a transmission roller, with stabilizing connecting rods fixed at both ends of the transmission roller, and the stabilizing connecting rods are movably sleeved inside the stabilizing sleeve.

[0014] Preferably, each swing arm mechanism includes a swing arm movably sleeved on the side of the stabilizing sleeve, one end of the swing arm being fixed with a sliding sleeve, the sliding sleeve being slidably connected in an arc-shaped groove.

[0015] Preferably, a bearing is fixed to the other end of the swing arm, and a positioning ring is fixed to one end of the bearing. A positioning rod is threaded to the side of the positioning ring.

[0016] The positioning ring is movably sleeved on the side of the stabilizing sleeve, and the positioning rod is attached to the stabilizing sleeve at a set position.

[0017] Preferably, a torsion spring is movably sleeved on the side of the bearing, and the two ends of the torsion spring are fixed to the opposite sides of the swing arm and the positioning ring, respectively.

[0018] Preferably, the pressing mechanism includes a pressing roller, with pressing connecting rods fixed at both ends of the pressing roller, and the pressing connecting rods are movably sleeved inside the sliding sleeve.

[0019] Preferably, a sponge layer is fixed to the side of the pressing roller, and the sponge layer is adhered to the surface of the sticker adhesive layer.

[0020] Preferably, the linkage mechanism includes two gears: a drive gear and a transmission gear. The drive gear is fixed on a stabilizing connecting rod at one end of the transmission roller, and the transmission gear is fixed on a pressing connecting rod at one end of the pressing roller. The two gears are meshed with a transmission toothed belt on their sides.

[0021] Preferably, the drive gear is fixed on the output end of the drive motor.

[0022] Compared with the prior art, the adjustable tensioning device for sticker adhesive processing provided by this utility model has the following advantages:

[0023] 1. This adjustable tensioning device for sticker adhesive processing uses a torsion spring to provide constant downward pressure, driving the swing arm mechanism and pressing roller to consistently apply a downward clamping force to the sticker adhesive layer. When the material experiences momentary slack, the swing arm swings downward under the action of the torsion spring, automatically increasing the wrap angle and tension, instantly tightening the material. Conversely, when the material is too tight, it can overcome the torsion spring force and swing upward to buffer the tension, ensuring that the sticker adhesive layer can always maintain a constant and suitable tension during processing. This effectively eliminates wrinkling, slack, and overstretching, greatly improving processing quality.

[0024] 2. This adjustable tensioning device for sticker adhesive processing, through the design of a positioning ring and a positioning rod, allows users to simply loosen the positioning rod and rotate the positioning ring to change the preload of the torsion spring. After adjustment, locking the positioning rod will fix the device, making the tension setting quick and linear. It can flexibly adapt to various specifications of sticker adhesive materials, from thin to thick, greatly enhancing the process adaptability and production efficiency of the equipment.

[0025] 3. The adjustable tensioning device for sticker adhesive processing uses a sponge layer covering the pressing roller to press the material surface while rotating together with the pressing roller. This effectively removes dust, debris, and other contaminants that may have adhered to the sticker adhesive layer during transport, forming an integrated tensioning and cleaning function. Thus, online cleaning is achieved without the need for separate equipment, ensuring the cleanliness and quality of subsequent processes. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0038] Please see Figure 1 - Figure 7 As shown, the adjustable tensioning device for sticker adhesive processing proposed in this embodiment includes a conveying component 1. The conveying component 1 includes two sets of stabilizing mechanisms 11 arranged symmetrically, and a transmission mechanism 12 disposed therebetween.

[0039] The stabilizing mechanism 11 provides rigid support. The mechanism includes a right-angled stainless steel triangular plate 111 arranged vertically. A stabilizing sleeve 112 with a diameter of 5cm and a wall thickness of 1cm is fixed horizontally at the right-angle position of the triangular plate 111. The other two corners are provided with connected arc-shaped grooves 113, with a width of 4cm.

[0040] It should be further explained that the opposite ends of the stabilizing sleeves 112 in the two sets of stabilizing mechanisms 11 are fixed to the corresponding surfaces inside the processing platform, and the stabilizing sleeves 112 are connected to the outer wall.

[0041] The transmission mechanism 12 is used to transport the adhesive layer of the sticker. The mechanism includes a transmission roller 121 with a diameter of 6.5 cm. At both ends of the transmission roller 121, there are stabilizing connecting rods 122 with a diameter of 3.8 cm. The stabilizing connecting rods 122 are movably sleeved in the stabilizing sleeve 112 to ensure the stability of the rotation of the transmission roller 121.

[0042] An adjustment component 2 is installed on the conveying component 1. The adjustment component 2 includes two sets of swing arm mechanisms 21 arranged symmetrically, and a pressing mechanism 22 disposed between them.

[0043] The swing arm mechanism 21 is used to adaptively adjust the tension. The mechanism includes a swing arm 211. Both ends of the swing arm 211 are provided with an interface with an inner diameter of 5.2 cm. One interface is movably sleeved on the side of the stabilizing sleeve 112, and a sliding sleeve 212 with a diameter of 5 cm and a wall thickness of 1 cm is fixed in the other interface. The sliding sleeve 212 is slidably connected in the arc groove 113 to ensure the stability of the swing arm 211.

[0044] Meanwhile, the side of the stabilizing sleeve 112 is also fitted with a bearing 213 with an inner diameter of 5.2cm and a positioning ring 214. The outer ring and inner ring of the bearing 213 are fixed to the corresponding surfaces of the swing arm 211 and the positioning ring 214, respectively.

[0045] Furthermore, the side of the positioning ring 214 has a circular hole that passes through it, and a positioning rod 215 is threaded into the hole. By rotating the positioning rod 215 clockwise or counterclockwise, the positioning rod 215 can gradually move into or out of the ring. When moving inward, the positioning rod 215 can fit tightly against the side of the stabilizing sleeve 112, thereby fixing the position of the positioning ring 214 on the side of the stabilizing sleeve 112.

[0046] In addition, a torsion spring 216 is movably sleeved on the side of the bearing 213. The two ends of the torsion spring 216 are fixed to the opposite surfaces of the swing arm 211 and the positioning ring 214, respectively. When the positioning ring 214 is in a fixed state, the torsion of the torsion spring 216 drives the swing arm 211 to swing around the stabilizing sleeve 112 as the axis, so that the other end of the swing arm 211 drives the sliding sleeve 212 to slide down along the arc groove 113. Thus, the tension is adaptively adjusted according to the tightness of the sticker adhesive layer, ensuring that the sticker adhesive layer is always in a taut state.

[0047] The pressing mechanism 22 is used to adaptively press the adhesive layer of the sticker. The mechanism includes a pressing roller 221 with a diameter of 6.5 cm. Pressing connecting rods 222 with a diameter of 3.8 cm are fixed at both ends of the pressing roller 221. The pressing connecting rods 222 are movably sleeved in the sliding sleeve 212 to ensure the stability of the rotation of the pressing roller 221. When the swing arm 211 is driven by the torque of the torsion spring 216, the swing arm 211 drives the pressing connecting rods 222 to swing downward through the sliding sleeve 212, so that the pressing roller 221 is pressed tightly against the surface of the sticker adhesive layer.

[0048] Meanwhile, a sponge layer 223 is fixed to the side of the pressing roller 221. When rotating in the pressed state, the sponge layer 223 cleans the surface of the sticker adhesive layer.

[0049] It should be further explained that when the pressing roller 221 installed at one end of the swing arm 211 is attached to the adhesive layer of the sticker, and the positioning ring 214 is in an active state, the torque value of the torsion spring 216 can be adjusted by rotating the ring.

[0050] One end of the conveying component 1 is equipped with a drive component 3, which includes a drive motor 31 that provides driving force. The motor is fixed to the side of the conveying platform by bolts, and the output end has a bidirectional rotation function and is connected to an independent wired and wireless controller.

[0051] The drive motor 31 is connected to a linkage mechanism 32 for controlling the synchronous operation of the transmission mechanism 12 and the pressing mechanism 22. This mechanism includes two gears: a drive gear 321 and a transmission gear 322. One end of the drive gear 321 is fixed to a stabilizing connecting rod 122 at one end of the transmission roller 121, and the other end is fixed to the output end of the drive motor 31. The transmission gear 322 is fixed to a pressing connecting rod 222 at one end of the pressing roller 221, and the two gears are meshed with a transmission toothed belt 323 on their sides. When the drive motor 31 is operating, its output end drives the drive gear 321 to rotate, which causes the stabilizing connecting rod 122 to drive the transmission roller 121 to convey the adhesive layer on the side. At the same time, the transmission toothed belt 323 meshing on the side of the drive gear 321 drives the transmission gear 322 to rotate, which causes the pressing connecting rod 222 to drive the pressing roller 221 to rotate, so that the sponge layer on its side cleans the surface of the adhesive layer.

[0052] The working principle of the adjustable tensioning device for sticker adhesive processing proposed in this embodiment is as follows: During use, the drive motor 31 operates, causing its output end to drive the drive gear 321 to rotate, thereby driving the transmission roller 121 to rotate and convey the sticker adhesive layer. At the same time, through the meshing force of the transmission belt 323 with the drive gear 321 and the transmission gear 322, the transmission gear 322 drives the pressing roller 221 to rotate, so that the sponge layer 223 on its side cleans the surface of the sticker adhesive layer. Meanwhile, under the torsional force of the torsion spring 216, the angle of the swing arm 211 is automatically adjusted, thereby driving the pressing roller to press down, increasing the tension, and ensuring that the sticker adhesive layer is in a taut state.

[0053] To increase or decrease the tension, rotate the positioning rod 215 in the opposite direction to disengage its front end from the stabilizing sleeve 112. Then, rotate the positioning ring 214 in both directions to adjust the torque value of the torsion spring 216 until the adjustment is complete. Finally, rotate the positioning rod 215 again to make its front end fit tightly against the side of the stabilizing sleeve 112 to fix the positioning ring 214.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
