Description

Technical Field

[0001] The present invention relates to the technical field of adhesive tape machines, in particular to a wet water adhesive tape machine. Background Art

[0002] The wet water tape machine is a device that integrates intelligent control and efficient production. It uses water activation technology to convert ordinary tape into ready-to-use wet water tape, which is specially designed for sealing and pasting scenarios.

[0003] The wet water tape dispensers currently on the market generally consist of a frame for placing the tape roll and a water coating device located at the tape outlet. The water coating device contains a water-absorbing material such as felt or sponge. A water tank is provided at the rear of the frame, and the felt is placed in the water tank to keep it moist. The moistened felt comes into contact with the adhesive material of the tape, thus giving the tape stickiness. In addition, the device is equipped with a cutter for cutting the moistened and sticky tape. This design allows the user to pull out the tape wound on the tape reel and rinse it with water while applying the rinsed portion to the object to be bonded until the tape reaches the desired length. The cutter is then used to cut the tape, making the operation very convenient.

[0004] However, traditional wet water tape dispensers have many shortcomings in actual applications, such as jamming, slipping and creases caused by uneven pressure on the conveyor rollers, or requirements for the thickness of the tape, which makes it impossible to adapt to all tapes. For example, the felt is in contact with water for a long time, causing its structure to become loose, deformed, moldy and sticky, affecting the water coating effect, and even causing the adsorbed impurities and dirt to be transferred to the tape, affecting the tape's viscosity.

[0041] First embodiment, reference Figures 1-15 .

[0042] This embodiment provides a wet tape dispenser, comprising a frame 1 and a film limiting device 2, a tape conveying device 3, a cutter device 4, and a water coating device 5, which are sequentially arranged within the frame 1 along the tape conveying direction. The wet tape dispenser operates as follows: after the film tape passes through the film limiting device 2 for width adjustment, the film is transported by the tape conveying device 3 via a driving roller assembly 31 and a driven roller assembly 32. With the coordinated operation of a pre-tightening assembly, the film is smoothly conveyed to the water coating device 5 through friction. A water pump 62 supplies a fixed amount of water from a water tank 51 to a water trough 52. After fully absorbing the fixed amount of water, a water suction roller 53 adheres tightly to the tape, evenly moistening the adhesive surface and activating the water-soluble colloid. The cutter assembly, driven by a worm gear, drives the upper and lower blades to cut vertically. Users can select sealing modes such as "straight" or "cross" on the wet tape dispenser's touchscreen. The whole machine is easy to operate. The water tank 52 and the suction roller 53 can be pulled out horizontally for cleaning, which takes into account both efficient production and convenient maintenance. The wetted tape can be directly used for carton sealing, achieving efficient operation. The specific structure is as follows:

[0043] like Figure 2-6 The specific structure of the film limiting device 2 is as follows: Figure 2The frame 1 includes a film placement cavity 11, and the film limiting device 2 is placed in the film placement cavity 11; the film limiting device 2 includes two limiting plates 21, a linear slide assembly 22 and a push rod assembly 23 that are symmetrically arranged on the left and right; a pin shaft 111 is provided along the width direction of the film placement cavity 11, and the limiting plate 21 is movably assembled on the pin shaft 111 and moves axially along the pin shaft 111; the limiting plate 21 is movably matched with the linear slide assembly 22, and the linear slide assembly 22 is linked with the push rod assembly 23; the film limiting device 2 adjusts the axial spacing width of the two limiting plates 21 through the linkage of the linear slide assembly 22 and the push rod assembly 23.

[0044] like Figure 6 The linear slide assembly 22 includes a slide plate 221 and two first slide grooves 222 arranged on the slide plate 221. A boss 211 is provided at the bottom of the two limit plates 21. The boss 211 is placed in the first slide groove 222 and is movable along the length direction of the first slide groove 222; the first slide groove 222 and the pin shaft 111 are non-parallel in the projection plane, and there is a fixed angle between the two; the slide plate 221 is connected to the push rod assembly 23, and the push rod assembly 23 drives the slide plate 221 to move back and forth along the conveying direction of the tape, and the first slide groove 222 and the boss 211, the limit plate 21 and the pin shaft 111 are movable to adjust the axial spacing width of the two limit plates 21.

[0045] like Figure 3 The linear guide rail assembly 22 is arranged on the bottom outer side of the film placement chamber 11, as shown in FIG. Figure 4 A through slot 113 is provided at the bottom of the film placement chamber 11, and the pin 111 is inserted into the through slot 113, the limiting plate 21 is inserted on the pin 111, and the protruding column 211 at the bottom of the limiting plate 21 passes through the through slot 113 and is connected to the first sliding slot 222 on the slide 221 at the bottom of the film placement chamber 11.

[0046] like Figure 6 The push rod assembly 23 includes a push block 231 and a connecting rod 232, and the connecting rod 232 is connected to the push block 231 and the slide 221 respectively; a second slide groove 112 (such as Figure 5 ); the push block 231 slides with the second chute 112, and the push block 231 moves back and forth in the second chute 112 along the tape conveying direction, and is linked to the slide 221 through the connecting rod 232. The push block 231 is connected to the slide 221 at the bottom of the film placement chamber 11 by the connecting rod 232 to achieve linkage.

[0047] A modular limit device is used to improve the adaptability and alignment accuracy of the tape. The slide-push rod linkage drives the axial synchronous displacement of the left and right limit plates 21, adjusting the axial spacing between the two limit plates 21 to achieve width adjustment and axial alignment stability for 36mm-80mm tape rolls. This allows for rapid adaptation to tape rolls of varying widths without the need for frequent component replacement, greatly improving the versatility and flexibility of the equipment. The active coordination of the limit plate 21 and the linear guide rail assembly 22, combined with the axial movement of the pin 111, ensures limit accuracy and ease of operation, making the adjustment of the limit plate 21 more stable and effectively preventing the tape from shifting during transport, thereby improving the tape's alignment accuracy.

[0048] like Figure 7-10 The specific structure of the belt conveyor 3 is as follows: Figure 7 The belt conveying device 3 includes an active roller group 31 and a driven roller group 32 for conveying the belt. The driven roller group 32 includes a driven roller 321 and a pre-tightening component. The driven roller 321 is movably matched with the frame 1 through the pre-tightening component; the driven roller 321 forms dynamic pressure in the direction toward the belt with the cooperation of the pre-tightening component.

[0049] like Figure 8 The pre-tightening assembly includes an elastic member 322 and a lower roller adjustment block 323. One end of the vertical elastic member 322 is connected to the top of the frame 1, and the other end is connected to the lower roller adjustment block 323. The lower roller adjustment block 323 is provided with pressure blocks 324 on both sides along the length direction. The driven roller 321 includes a rotating shaft 325. The frame 1 is provided with a third slide groove 13 on both sides along the width direction. The driven roller 321 is movably assembled in the third slide groove 13 through the rotating shaft 325. The pressure block 324 is pressed on the rotating shaft 325, and the pressure block 324 is placed in the third slide groove 13 (as shown in FIG. Figure 7); the driven roller 321 is movably assembled in the third slide groove 13 through the rotating shaft 325, and the third slide groove 13 is arranged vertically; the rotating shaft 325 squeezes the elastic member 322 through the lower roller adjustment block 323, so that the rotating shaft 325 can move up and down vertically in the third slide groove 13. The beneficial effect of the pre-tightening assembly in this embodiment compared to the conventional method of achieving pre-tightening through the spring lever principle is that, through the cooperation of the third slide groove 12, the rotating shaft 325, and the lower roller adjustment block 323, the pre-tightening assembly has an up and down guiding function, which can solve the problems of limited pre-tightening range, insufficient flexibility, and frequent adjustment in conventional technologies. Specifically, by designing the length of the third slide groove 13, the up and down movement range of the driven roller 321 is expanded, and sufficient up and down movement space is provided for the driven roller 321, which can effectively solve the problem of limited pre-tightening range. The vertical arrangement of the third slide groove 13 provides a clear up and down movement path for the rotating shaft 325 of the driven roller 321. This design eliminates the limitations of traditional lever structures on the vertical movement range of the driven roller 321. Instead, it is directly determined by the length of the chute and the deformation range of the elastic member 322. The elastic properties of the elastic member 322 allow the preload force to be automatically adjusted based on the actual position of the driven roller 321. When the driven roller 321 moves up and down due to load fluctuations, the elastic member 322 deforms accordingly, automatically adjusting the preload force and ensuring that the driven roller 321 always maintains the appropriate preload state. This automatic adjustment capability avoids the problem of insufficient or excessive preload force caused by load fluctuations in traditional preload methods, thereby improving the flexibility of the preload assembly.

[0050] Dynamic pressure compensation mechanism: The lower roller adjustment block 323, preloaded by the elastic member 322, cooperates with the third chute 13 of the main frame 1 to form a floating driven roller design. This, combined with roller surface friction and a linear pressure gradient, automatically adjusts pressure based on the thickness and tension of the tape, ensuring slip-free, continuous conveying of the tape. This improves the stability and reliability of tape conveying and is particularly suitable for tapes of varying materials and thicknesses. The elastic member 322 is linked to the lower roller adjustment block 323: The elastic properties of the elastic member 322 enable the lower roller adjustment block 323 to automatically adjust its position based on the tape tension, ensuring optimal contact pressure between the driven roller 321 and the tape. This dynamic adjustment mechanism effectively prevents slippage or damage to the tape during conveying due to insufficient or excessive pressure.

[0051] like Figure 10The active roller assembly 31 includes a roller 311 and a power drive device. The power drive device includes a first motor 312 that drives the roller 311 to rotate. The first motor 312 includes a motor connecting shaft 313. A polygonal slot 314 is provided inside the roller 311. The motor connecting shaft 313 includes a polygonal connecting portion 315 corresponding to the polygonal slot 314. The motor connecting shaft 313 is inserted into the polygonal slot 314, and the polygonal slot 314 and the polygonal connecting portion 315 form a limited fit. The first motor 312 is a DC motor. The power system is driven by the DC motor and drives the active roller assembly 31 to rotate through the quadrilateral anti-slip connecting roller 311, thereby achieving continuous conveying of the tape. It should be noted that the structure of the polygonal slot 314 and the polygonal connecting portion 315 can be specifically configured as a quadrilateral or pentagonal slot and connecting portion, but is not limited to a quadrilateral or pentagonal arrangement. Preferably, in this embodiment, the quadrilateral slot and quadrilateral connecting portion are used as an example of a limited fit.

[0052] like Figure 11-14 The specific structure of the cutter assembly is as follows: Figure 11 The cutter assembly includes an upper blade 41, a lower blade 42, and a blade drive assembly. The upper blade 41 and the lower blade 42 are arranged vertically. The upper blade 41 is fixed to the frame 1, and the lower blade 42 is moved toward or away from the upper blade 41 by the blade drive assembly. The upper blade 41 adopts a V-shaped carbide cutting edge design, which enhances cutting durability and precision. Carbide material has high hardness and wear resistance.

[0053] like Figure 14 The frame 1 also includes a chamber 12 for mounting a lower blade 42, the chamber 12 has an elastic sheet 44 built in, and the elastic sheet 44 includes an elastic convex 45 (such as Figure 13 ), the elastic bump 45 abuts against the blade of the lower blade 42, pushing the lower blade 42 in a direction toward the upper blade 41. The elastic bump 45 provides contact pressure, and the lateral elastic thrust provided by the elastic bump 45 keeps the lower blade 42 horizontally close to the upper blade 41. When the upper and lower blades 41 and 42 are closed, contact pressure is applied, ensuring zero clearance between the double-edged shearing surfaces, achieving quick and one-time severing of the tape, and achieving a clean and efficient cutting effect.

[0054] like Figure 12 The blade drive assembly is a worm gear transmission assembly 43, and a transverse groove 421 is provided on the blade body of the lower blade 42 (such as Figure 13), the worm gear of the worm gear transmission assembly 43 extends outward and is provided with a drive rod 431, which is inserted into the transverse slot 421 to form a crank slider 522 mechanism. The worm gear transmission assembly 43 drives the lower blade 42 through the cooperation between the drive rod 431 and the transverse slot 421. The circular rotation input by the second motor 432 in the worm gear transmission assembly 43 is converted into vertical reciprocating motion, which is then achieved through the crank slider 522 mechanism to achieve precise cutting of the blade.

[0055] like Figure 15 The specific structure of the water coating device 5 is as follows: the water coating device 5 also includes a water tank 51 and a water trough 52 detachably assembled on the water tank 51; a water suction roller 53 is detachably assembled in the water trough 52, and the water suction roller 53 is wetted with water for water coating the tape. The water suction roller 53 is rotatably mounted in the water trough 52. The water tank 51 is in communication with the water trough 52. The water tank 51 can supply a fixed amount of water to the water trough 52 via a water pump. The water pump supplies a fixed amount of water to the water trough 52 based on the amount of water absorbed by the water suction roller 53. The fixed amount of water flowing into the water trough 52 is absorbed by the water suction roller 53. No water is stored in the water trough 52, thereby preventing the water suction roller 53 from being immersed in water for a long time and absorbing excessive water. The water suction roller 53 can be a roller shaft with water absorption properties, including but not limited to a sponge roller, a foam roller, a fiber roller, a rubber roller, etc.

[0056] The water coating device 5 also includes an upper pressure roller 54; the upper pressure roller 54 cooperates with the water absorption roller 53 to transport the tape; the upper pressure roller 54 is movably assembled on the frame 1 through a rotating shaft 541, and the upper pressure roller 54 ensures contact between the tape and the water absorption roller 53 to ensure uniform water coating. Figure 15The power drive device also includes a gear transmission mechanism 55, which includes a driving wheel 551 and several driven wheels. The motor connecting shaft 313 passes through the polygonal slot 314 and is connected to the driving wheel 551; the driven wheel includes a driven gear set 552, a first gear 553, a second gear 554, and a third gear 555; the first gear 553 and the second gear 554 are arranged on the rotating shaft 541, and the third gear 555 is arranged on the roller shaft 531 of the water-absorbing roller 53; the driving wheel 551 and the first gear 553 are respectively engaged with the driven gear set 552, and the second gear 554 is engaged with the third gear 555; the power drive device drives the roller 311, the upper pressure roller 54 and the water-absorbing roller 53 to roll synchronously through the cooperation of the first motor 312 and the gear transmission mechanism 55. The synchronous rolling can ensure the stability and continuity of the tape during transportation, avoid the tape jamming or slipping caused by inconsistent speed, thereby improving the overall production efficiency. Synchronous rolling allows each roller to maintain a consistent speed, reducing friction and wear caused by speed differences, reducing equipment wear and lowering maintenance costs. The suction roller 53 and upper pressure roller 54 maintain a consistent speed, ensuring that the tape is evenly coated with the appropriate amount of water as it passes through the suction roller 53. Synchronous rolling precisely controls the rotational speed of the suction roller 53, preventing it from absorbing too much water due to excessive speed, and ensuring a consistent wetting effect.

[0057] The detachable structure of the suction roller 53 and the water trough 52 is specifically as follows: U-shaped grooves 521 are provided on the inner walls on both sides of the length direction of the water trough 52, and the roller shaft 531 of the suction roller 53 is inserted into the U-shaped grooves 521. The suction roller 53 can be pulled out upward along the opening of the U-shaped grooves 521; when the water trough 52 is assembled in the water tank 51, the second gear 554 is engaged with the third gear 555, so that the roller shaft 531 of the suction roller 53 is pressed into the U-shaped grooves 521. The water tank 52 is detachable, and the water tank 52 includes a slider 522 arranged at the bottom and an insertion rod 523 arranged on one side. The water tank 51 is provided with a guide rail 511 and a socket 512 corresponding to the slider 522 and the insertion rod 523 respectively; when the slider 522 is inserted into the guide rail 511, the insertion rod 523 is inserted into the socket 512, and the water tank 52 is fixed on the water tank 51; through the sliding cooperation between the slider 522 and the guide rail 511, the water tank 52 can be pulled and separated relative to the water tank 51 in the horizontal direction.

[0058] The design of the quick-detachable water trough 52 and the water suction roller 53 enables rapid maintenance and cleaning of the water trough 52 and the water suction roller 53. The water trough 52 can be quickly pulled apart in the horizontal direction through the sliding cooperation of the slider 522 and the guide rail 511, and the water suction roller 53 is fixed by the U-shaped slot 521. The water suction roller 53 supports tool-free disassembly, which is convenient for disassembly and installation. The foreign matter in the water suction roller 53 and the water trough 52 can be cleaned immediately, so that the user can easily replace or clean the water suction roller 53 during daily maintenance, ensuring that the water coating device 5 always maintains a good working condition.

[0059] The second embodiment, as Figure 16-18 .

[0060] Another embodiment of the water coating device is provided. Figure 16-18 The specific structure of the water coating device 5 is as follows: the water coating device 5 also includes a water tank 51 and a water trough 52 detachably assembled on the water tank 51; a water suction roller 53 is detachably assembled in the water trough 52, and the water suction roller 53 is wetted with water for water coating the tape. The water trough 52 includes a water inlet 524 and a water outlet 525, which are respectively connected to the water tank 51. The water tank 51 is pumped by a water pump and supplied to the water trough 52 from the water inlet 524. The water trough 52 returns water to the water tank 51 from the water outlet 525, forming a water cycle. The water in the water tank 51 is transported to the water trough 52 by a water pump 62. Water enters the water inlet 524 and exits the water outlet 525. After the water is discharged, there is no water left in the water trough 52. The water trough 52 passes water during the water cycle and absorbs water through the porous water suction roller 53 to achieve uniform wetting of the back of the tape. When not in use, there is no water in the water tank 52, which can keep the water-absorbing roller 53 dry and facilitate replacement, while preventing colloid precipitation from affecting the water coating effect.

[0061] The water inlet 524 is connected to the water outlet 514 of the water tank 51 via a pipe. The water outlet 525 of the water trough 52 is located at the same position as the plug rod 523. A water outlet channel is provided within the plug rod 523, directly connecting to the interior of the water trough 52. Water in the water trough 52 flows directly out of the water outlet channel. The water tank 51 has a through hole directly provided at the socket 512, which is directly connected to the water tank 51 using the structure of the socket 512. The socket 512 serves as the water inlet. When the water trough 52 is installed on the water tank 51, the plug rod 523 is inserted into the socket 512, completing the connection between the water outlet 525 of the water trough 52 and the water inlet of the water tank 51.

[0062] The third embodiment, as Figure 19-20 .

[0063] The cutter assembly 4 is detachably mounted in the frame 1 ; the frame 1 is provided with an opening 14 at the upper end where the cutter assembly 4 is located, and the display assembly 15 can be detachably assembled at the opening 14 , and the cutter assembly 4 can be detached from the frame 1 upward from the opening 14 .

[0064] In this embodiment, the cutter assembly 4 adopts a modular design so that it can be completely detached from the frame 1 through the opening 14 relative to the frame 1. During assembly, the cutter assembly 4 is locked in the frame 1 by screws 46. During disassembly, it is only necessary to remove the screws 46 to pull the cutter assembly 4 out of the opening 14. The detachable structure makes the cutter assembly 4 replaceable and repairable, and has high practicality.

[0065] The fourth embodiment, as Figure 21 .

[0066] The water coating device 5 includes a self-cleaning system 6. The specific operation of the self-cleaning system 6 is as follows: the self-cleaning system 6 includes an electrode assembly 61, and the pipelines include a first pipeline 63, a second pipeline 64 and a third pipeline 65. The water tank 51 is connected to the water pump 62 and the water tank 52 through the first pipeline 63 and the third pipeline 65 respectively. The water pump 62 is connected to the water tank 52 through the second pipeline 64; the electrode assembly 61 is placed in the water tank 51, and the water pump 62 is connected to a sewage pipe 66.

[0067] Leak-proof design: The water tank 51, sink 52, and pipe connections are connected by rubber plugs for an interference fit. Combined with the quick-release guide rails 511 and sliders 522, this mechanism allows for quick maintenance and cleaning of the sink 52 and suction roller 53. The water inlet of the water tank 51 is sealed with a rubber seal at the water tank cover 513, while the outlet 525 of the sink 52 and the water tank 51 are sealed with a rubber plug for an interference fit, preventing leaks.

[0068] The water pump 62 is a bidirectional water pump 62, and the water pump 62 adopts a peristaltic pump; when the water coating device 5 is used for water coating, the water pump 62 pumps water in the forward direction, extracts water from the water tank 51 through the first pipe 63, and sends it to the water tank 52 through the second pipe 64. The water tank 52 returns water to the water tank 51 through the third pipe 65 to form a water cycle. In this process, the colloid is attached to the third pipe 65 through the transmission of water, causing the size of the water flow to be abnormal; when the self-cleaning system 6 performs self-cleaning, the electrode assembly 61 is energized, and the water pump 62 pumps water in the reverse direction. The water in the water tank 51 flows to the water pump 62 through the third pipe 65, the water tank 52, and the second pipe 64, and is discharged through the drain pipe 66; the electrode of the electrode assembly 61 is inserted into the water in the water tank 51, and the electrode assembly 61 is energized to generate an electrode effect, agglomerating metal impurities in the water. The metal impurities adsorb the colloid in the third pipe 65 with the water flow. The metal impurities combine with the sticky colloid and are discharged from the drain outlet along the water flow, thereby realizing automatic cleaning of the pipeline.

[0069] Water pump 62 utilizes a bidirectional pumping design. During coating, it pumps water forward to create a water circulation system, ensuring that the water in water tank 52 remains clean. During self-cleaning, it pumps water backward to discharge the water in water tank 51 through the pipes, removing impurities and colloids within the pipes. The self-cleaning system 6 uses reverse pumping from water pump 62, combined with electrode-agglomerated metal impurities, to automatically remove residual colloids from the pipes and prevent blockages. This design not only improves the cleaning efficiency of the equipment, but also extends its service life and reduces equipment failures caused by pipe blockages.

[0070] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with this technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the scope of protection of the present invention.
