[0002] The transparent tape is made by roughening the surface of one side of the original BOPP film after high-voltage corona treatment, and then coating glue on the rough surface and dividing it into small rolls through strips. The existing transparent tape usually has acrylic glue on the surface, also called pressure-sensitive adhesive, and its main component is tincture. Tincture is a high-molecular active substance, and the temperature has a certain effect on the molecular activity.

Since the tape is not tensioned, the glue coating force is prone to be insufficient during the process of being coated by the glue-coating roller, resulting in average glue coating quality of the tape.

At the same time, the vertical position height of the tensioning roller can be adjusted by turning the lifting screw forward and reversely, so that the tensioning force of the adhesive tape can be adjusted by adjusting the height of the tensioning roller, which is convenient for adaptively adjusting the tensioning force of the tensioning roller according to adhesive tapes of different specifications, thereby enriching the adhesive tape. The general scope of use of the tape tensioning assembly. Specifically, during operation, when the position height of the tensioning roller needs to be adjusted, the locking nut is turned close to the handle, and then the handle is held to drive the lifting screw to rotate clockwise or counterclockwise. During the forward rotation, the lifting screw drives the tensioning roller to rise and increase the tensioning force on the tape passing above. During the reverse rotation, the lifting stud drives the tensioning roller to descend and weaken the tensioning force on the tape passing above, thereby adjusting the tensioning force of the tape. At the same time, during the lifting and lowering adjustment of the tensioning roller, the guide rod can slide vertically along the guide hole to guide and correct the lifting and lowering of the tensioning roller, thereby preventing the tensioning roller and the U-shaped frame from moving with the lifting screw The rod rotates and becomes misaligned with the glue coating roller. Specifically, when the adhesive tape is coated with glue, the adhesive tape passes through the gap between the adhesive coating roller and the tensioning roller, and the two ends of the adhesive tape are respectively connected to the external discharging drum mechanism and the winding drum mechanism. By adjusting the height of the tensioning roller position, the adhesive tape can be tensioned on the lower outer portion of the adhesive coating roller and tightly attached to the adhesive coating roller.

In the process of rotation, the adhesive coating roller will coat the adhesive surface of the adhesive tape with glue to complete the gluing operation. At the same time, during the gluing process of the tape, since the liquid leveling plates are coaxially arranged on both sides of the upper outer periphery of the glue coating roller of the glue coating assembly, and a certain gap is left between the inner periphery of the liquid leveling plates and the outer periphery of the glue coating roller, the setting of the liquid leveling plates can make the glue discharged through the liquid outlet pipe evenly distributed on the surface of the glue coating roller, thereby improving the uniformity of gluing the adhesive tape. Specifically, when it comes to the combination of the glue coating roller and the mounting plates at the two side positions, the limiting studs are vertically slidably matched with the limiting grooves, and the limiting nuts are installed and tightened on the surface of the mounting plates. The glue coating roller can be detachably fixed between the mounting plates at the two side positions and located below the liquid outlet pipe. At the same time, since the bottom ends of the limiting grooves are open,The fixing assembly and disassembly method of the glue coating roller between the mounting plates at the two sides is simple and easy to operate, which is convenient for quickly fixing the glue coating roller between the mounting plates at the two sides for glue coating and use, and is also convenient for later maintenance after the glue coating roller is disassembled. It should be noted that before disassembling the glue coating roller, the top plate and the adhesive tape gluing assembly should be disassembled between the top of the side seats at the two sides. Specifically, when the top plate and the adhesive tape gluing assembly are combined between the top of the side seats at the two sides, the top plate and the adhesive tape gluing assembly can be detachably fixed between the two sides by vertically sliding cooperation between the matching seat and the matching groove and horizontally sliding cooperation between the limiting rod and the limiting hole. The top of the side seat at the side position is suspended above the tape tensioning assembly, and the combination of the top plate and the tape gluing assembly at the top of the side seat at the two side positions is simple and easy to operate, which makes it convenient to glue the tape passing below through the tape gluing assembly. When the top plate and the tape gluing assembly need to be removed for maintenance later, it is only necessary to simultaneously hold the handles at the two side positions and pull them outward, and let the limit rods all disengage from the limit holes by the stretched springs, and then keep pulling the limit rods outward and hold the handles and lift them up to make the matching seat vertically disengage from the matching grooves, so that the top seat and the tape gluing assembly can be detached from the top of the side seats at the two side positions. The disassembly method of the top plate and the tape gluing assembly at the top of the side seats at the two side positions is simple and easy to operate, which is convenient for regular maintenance after the tape gluing assembly is disassembled in the later stage.

[0019] The beneficial effects are as follows: 1. The utility model is provided with a tape tensioning assembly below the tape gluing assembly, so that the tape can be tensioned by the tensioning roller of the tape tensioning assembly, and then the gluing surface of the tape can be closely attached to the gluing roller of the tape gluing assembly, thereby maintaining a good gluing force, which is beneficial to improving the gluing quality of the tape;

[0020] 2. The vertical position height of the tensioning roller can be adjusted by turning the lifting screw forward and reversely, so that the tensioning force of the tape can be adjusted by adjusting the height of the tensioning roller, which is convenient for adaptively adjusting the tensioning force of the tensioning roller according to tapes of different specifications, thus enriching the general use range of the tape tensioning assembly;

[0021] 3. Liquid leveling plates are coaxially arranged on both sides of the upper periphery of the glue coating roller of the tape gluing assembly, and a certain gap is left between the inner periphery of the liquid leveling plate and the periphery of the glue coating roller. Then, the setting of the liquid leveling plate can make the glue discharged through the liquid outlet pipe evenly distributed on the surface of the glue coating roller, thereby improving the gluing uniformity of the tape;

[0022] 4. The gluing roller can be detachably fixed between the mounting plates at both sides and located below the liquid outlet pipe by installing a limiting nut after the limiting stud and the limiting groove are vertically slidably matched and then tightened on the surface of the mounting plate. At the same time, the bottom ends of the limiting grooves are open. Then, the limiting stud can be slid down and out of the limiting groove by simply unscrewing the limiting nut, and the gluing roller can be removed from the mounting plates at both sides. The fixing combination and disassembly method of the gluing roller between the mounting plates at both sides are simple and easy to operate, which is convenient for quickly fixing the gluing roller between the mounting plates at both sides for gluing and use, and is also convenient for disassembling the gluing roller for maintenance at a later stage.

[0023] 5. The top plate and the tape gluing assembly can be detachably fixed to the top of the side seats at both sides and suspended above the tape tensioning assembly by means of vertical sliding cooperation between the matching seat and the matching groove and horizontal sliding cooperation between the limiting rod and the limiting hole.

[0043] See also Figure 1-Figure 9As shown, the tops of the side seats 3 at both sides are installed with disassembly assembly components 2, and the disassembly assembly components 2 are partially arranged on the side portions corresponding to the bottom surface of the top plate 1, and the top plate 1 is detachably connected to the side seats 3 through the disassembly assembly components 2, so as to detachably fix the top plate 1 and the adhesive tape gluing component 6 between the tops of the side seats 3 at both sides.

[0044] See also Figure 1-Figure 7As shown, a cross seat 4 is horizontally fixed between the middle parts of the side seats 3 at both sides, and a tape tensioning assembly 7 capable of vertically lifting and adjusting the height of the position is installed in the middle part of the cross seat 4, and the tape tensioning assembly 7 is located below the tape gluing assembly 6, so as to tension and support the tape through the tape gluing assembly 6. Specifically, the tape tensioning assembly 7 includes a lifting screw 705 and a tensioning roller 701, and the lifting screw 705 is vertically arranged and passes through the middle part of the cross seat 4 in a threaded engagement manner. The lifting screw 705 extends out of the bottom surface of the cross seat 4 and is coaxially engaged with a locking nut 709 on the periphery thereof, and the top end of the lifting screw 705 extending out of the top surface of the cross seat 4 is coaxially fixed to the inner ring of the bearing built into the bearing seat 2 708.

[0045] See also Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the tape gluing component 6 is optimized as follows. The detachable connection method between the mounting plate 603 and the gluing roller 606 is as follows: the bottom surface of the mounting plate 603 is vertically provided with a limiting groove 6012, and the limiting grooves 6012 at both sides are through grooves in the horizontal direction and are in contrast to each other. The end surfaces of the gluing roller 606 at both sides are coaxially fixed with a bearing seat 6011, and the bearing inner rings built in the bearing seats 6011 at both sides are coaxially fixed with limiting studs 609 arranged in the horizontal direction. The limiting studs 609 at both sides pass through the corresponding limiting grooves 6012 in a horizontal sliding fit manner, and the limiting studs 609 extend The parts outside the corresponding limit grooves 6012 are coaxially meshed with several limit nuts 6010. Such an arrangement makes it convenient to detachably fix the glue coating roller 606 between the mounting plates 603 at both sides and below the liquid outlet pipe 607 by installing the limit nuts 6010 and tightening them on the surface of the mounting plate 603 after the limit studs 609 are vertically slidably matched with the limit grooves 6012. At the same time, the bottom ends of the limit grooves 6012 are open, and then the limit studs 609 can slide out of the limit grooves 6012 by simply unscrewing the limit nuts 6010, so that the glue coating roller 606 can be removed from between the mounting plates 603 at both sides.

[0046] Further optionally, liquid leveling plates 605 are fixed between the mounting plates 603 on both sides at the front and rear positions of the upper outer periphery of the glue coating roller 606. The upper portions of the liquid leveling plates 605 are straight plates and are respectively located in front and rear of all liquid outlet pipes 607. The lower portions of the liquid leveling plates 605 are arc-shaped plates and are coaxially arranged on the outer periphery of the glue coating roller 606. The arrangement of the liquid leveling plates 605 can make the glue discharged through the liquid outlet pipes 607 evenly distributed on the surface of the glue coating roller 606, thereby improving the uniformity of gluing the adhesive tape. At the same time, a sealing cover 601 for controlling opening and closing is coaxially and detachably installed on the top of the liquid injection tube 602, and a solenoid valve 608 for controlling opening and closing is installed on the periphery of the liquid outlet tube 607. Preferably, the sealing cover 601 and the liquid injection tube 602 are detachably connected by threaded cooperation, and the opening and closing time of the solenoid valve 608 is adjustable. The purpose of such a setting is that the sealing cover 601 and the liquid injection tube 602 can be quickly combined and disassembled by twisting, and then it is convenient to add additional glue to the liquid storage box 604 through the liquid injection tube 602. At the same time, since the opening and closing time of the solenoid valve 608 is adjustable, the amount of glue discharged through the liquid outlet tube 607 can be regulated by adjusting the opening time of the solenoid valve 608. The limiting grooves 6012 are all waist-shaped grooves with open bottoms. Each limiting stud 609 is engaged with two limiting nuts 6010 with opposite rotation directions, so that the limiting stud 609 can smoothly slide out from the bottom of the limiting groove 6012. At the same time, by setting two limiting nuts 6010 with opposite rotation directions at the same time, a Tang's thread anti-loosening structure can be formed to ensure that the limiting nuts 6010 will not loosen naturally when tightened. The inner periphery of the lower part of the liquid-leveling plate 605 and the outer periphery of the glue-coating roller 606 are close to each other but not in contact, and the lowest position of the lower part of the liquid-leveling plate 605 is higher than the central axis of the glue-coating roller 606. This arrangement facilitates a certain gap between the liquid-leveling plate 605 and the glue-coating roller 606 so that the glue can flow and be evenly distributed on the outer periphery of the glue-coating roller 606.

[0047] See also Figure 3 , Figure 4 and Figure 5 As shown, the tape tensioning assembly 7 is optimized as follows: the cross-sectional shape of the tensioning roller 701 along the longitudinal vertical plane is elliptical, connecting shafts 706 are coaxially fixed at both ends of the tensioning roller 701, and the connecting shafts 706 pass through the vertical parts corresponding to the U-shaped frame 704 in a transverse sliding fit, and the parts of the connecting shafts 706 extending out of the outer sides of the vertical parts corresponding to the U-shaped frame 704 are coaxially detachably connected with locking rings 707, and the locking rings 707 are pressed against the outer surfaces of the vertical parts corresponding to the U-shaped frame 704. The purpose of such a configuration is to facilitate the stable combination and fixing of the tensioning roller 701 between the two side positions of the U-shaped frame 704, and also to facilitate the tensioning roller 701 to have a good appearance design style so as to have a tensioning and supporting effect on the tape.

[0048] Specifically with regard to the position of the lifting screw 705, the locking nut 709 is a hand-tightened knurled nut, and the bottom end of the lifting screw 705 is fixedly installed with a handle 7010 for easy holding, so that the locking nut 709 can be directly tightened or loosened by hand, and at the same time, it is convenient to smoothly turn the lifting screw 705 by holding the handle 7010. At the same time, the cross seat 4 is vertically provided with guide holes 703 on both sides of the lifting screw 705, and the guide holes 703 are vertically inserted with guide rods 702 in a coaxial sliding manner, and the top ends of the guide rods 702 are fixed to the bottom surface of the U-shaped frame 704, and the bottom ends of the guide rods 702 are not lower than the bottom end of the lifting screw 705. The advantage of such a setting is that during the lifting and lowering adjustment of the tensioning roller 701, the lifting and lowering of the tensioning roller 701 can be guided and corrected by the guide rods 702 sliding vertically along the guide holes 703, thereby preventing the tensioning roller 701 and the U-shaped frame 704 from being misaligned with the glue coating roller 606 as the lifting screw 705 rotates.

[0049] See also Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the disassembly and assembly assembly 2, the top plate 1 and the side seat 3 are respectively optimized as follows. Specifically, in the disassembly and assembly assembly 2, the horizontal cross-sectional shapes of the mating seat 205 and the mating groove 204 are both rectangular, the mating groove 204 is a blind groove in the vertical direction, and the bottom end of the mating seat 205 is in close contact with the bottom end of the corresponding mating groove 204, so that the mating seat 205 and the mating groove 204 have a good guiding and correcting design during the vertical sliding cooperation. At the same time, in the process of the mating seat 205 sliding vertically along the mating groove 204, when the limit hole 207 slides down with the mating seat 205 to be horizontally coaxial with the limit rod 206, an obvious prompt can be given by the bottom end of the mating seat 205 being in close contact with the bottom end of the corresponding mating groove 204. Specifically, with respect to the top plate 1 and the side seat 3, handles 101 for easy holding are installed on both sides of the top surface of the top plate 1, and the bottom surfaces of the side seats 3 are horizontally extended and fixed with fixing plates 5 for fixing at the installation position. This arrangement makes it easy to lift the top plate 1 and the adhesive tape gluing component 6 by applying force by holding the handles 101. At the same time, since the fixing plate 5 is extended from the bottom surface of the side seat 3, the side seat 3 can be smoothly fixed at the installation position by inserting screws through the fixing plate 5 to complete the placement.

[0050] With the above structure, specifically in the process of gluing the tape, since a tape tensioning assembly 7 is installed below the tape gluing assembly 6, the tape can be tensioned by the tensioning roller 701 of the tape tensioning assembly 7, and then the gluing surface of the tape can be made to be close to the gluing roller 606 of the tape gluing assembly 6, thereby maintaining a good gluing force, which is beneficial to improving the gluing quality of the tape. At the same time, the vertical position height of the tensioning roller 701 can be adjusted by twisting the lifting screw 705 in a forward and reverse manner, so that the tensioning force of the tape can be adjusted by adjusting the height of the tensioning roller 701, which is convenient for adjusting the tensioning force of the tensioning roller 701 according to tapes of different specifications. Adaptive adjustment enriches the general use range of the tape tensioning assembly 7. Specifically, when the position height of the tensioning roller 701 needs to be adjusted, the locking nut 709 is screwed close to the handle, and then the handle 7010 is held to drive the lifting screw 705 to rotate clockwise or counterclockwise. The lifting screw 705 drives the tensioning roller 701 to rise during the forward rotation to increase the tensioning force on the tape passing above. The lifting stud drives the tensioning roller 701 to descend during the reverse rotation to reduce the tensioning force on the tape passing above, thereby adjusting the tensioning force of the tape. At the same time, during the lifting and lowering adjustment process, the tensioning roller 701 can be adjusted by the guide rod 702 sliding vertically along the guide hole 703. The lifting and lowering of the tensioning roller 701 is guided and corrected to prevent the tensioning roller 701 and the U-shaped frame 704 from being misaligned with the glue coating roller 606 as the lifting screw 705 rotates. Specifically, when gluing the tape, the tape passes through the gap between the glue coating roller 606 and the tensioning roller 701, and the two ends of the tape are respectively connected to the external unwinding drum mechanism and the winding drum mechanism. By adjusting the position height of the tensioning roller 701, the tape can be tensioned on the outer lower part of the glue coating roller 606 and close to the glue coating roller 606. When the tape is wound up by the external winding drum mechanism, the glued surface of the tape will drive the glue coating roller 606 to rotate due to friction with the surface of the glue coating roller 606, so that the solenoid valve 608 is energized and opened. The glue in the liquid storage box 604 is discharged through the liquid outlet pipe 607 and falls to the upper outer part of the glue coating roller 606. The glue coating roller 606 will coat the glue on the gluing surface of the tape during its rotation to complete the gluing operation. At the same time, during the gluing process of the tape, since the glue coating roller 606 of the tape gluing assembly 6 is coaxially provided with liquid leveling plates 605 on both sides of the upper outer part, and a certain gap is left between the inner periphery of the liquid leveling plate 605 and the outer periphery of the glue coating roller 606, the setting of the liquid leveling plate 605 can make the glue discharged through the liquid outlet pipe 607 evenly distributed on the surface of the glue coating roller 606, thereby improving the gluing uniformity of the tape. Specifically, when it comes to the combination of the glue coating roller 606 and the mounting plates 603 at both sides,By means of vertically sliding fit between the limiting stud 609 and the limiting groove 6012, and then installing the limiting nut 6010 and tightening it on the surface of the mounting plate 603, the glue coating roller 606 can be detachably fixed between the mounting plates 603 at both sides and below the liquid outlet pipe 607. At the same time, since the bottom ends of the limiting grooves 6012 are open, it is only necessary to unscrew the limiting nut 6010 to make the limiting stud 609 slide out of the limiting groove 6012 and remove the glue coating roller 606 from between the mounting plates 603 at both sides. The fixing combination and disassembly method of the roller 606 between the mounting plates 603 at the two side positions is simple and easy to operate, which is convenient for quickly fixing the glue coating roller 606 between the mounting plates 603 at the two side positions for glue coating, and is also convenient for disassembling the glue coating roller 606 for maintenance at a later time. It should be noted that before disassembling the glue coating roller 606, the top plate 1 and the adhesive tape gluing assembly 6 should be disassembled from the top of the side seats 3 at the two side positions. Specifically, when the top plate 1 and the adhesive tape gluing assembly 6 are combined between the top of the side seats 3 at the two side positions, through The vertical sliding cooperation between the matching seat 205 and the matching groove 204 and the horizontal sliding cooperation between the limiting rod 206 and the limiting hole 207 can detachably fix the top plate 1 and the tape gluing component 6 on the top of the side seat 3 at both sides and suspend them above the tape tensioning component 7. The combination of the top plate 1 and the tape gluing component 6 on the top of the side seat 3 at both sides is simple and easy to operate, which makes it easy to glue the tape passing below through the tape gluing component 6. When the top plate 1 and the tape gluing component 6 need to be removed for maintenance later, it only needs to be removed. At the same time, the handles 203 at both sides are pulled outwards and the limit rods 206 are pulled out of the limit holes 207 by the springs 202 being stretched. Then, the limit rods 206 are pulled outwards and the handles 101 are lifted up to make the matching seat 205 vertically disengage from the matching groove 204. In this way, the top seat and the adhesive tape gluing assembly 6 can be detached from the top of the side seats 3 at both sides. The detachment method of the top plate 1 and the adhesive tape gluing assembly 6 at the top of the side seats 3 at both sides is simple and easy to operate, which is convenient for regular maintenance after the adhesive tape gluing assembly 6 is detached later.
