TECHNICAL FIELD
[0001] The utility model relates to a machine for water coating and cutting of adhesive tape. BACKGROUND
[0002] In the express logistics industry, packaging cartons need to be subjected to sealing process treatment. Currently, the sealing process of cartons at home and abroad generally uses plastic adhesive tape and paper wet adhesive tape, and the use of plastic adhesive tape causes pollution to the environment.
[0003] The wet adhesive tape machine is a machine for using the pollution-free treated paper adhesive tape (wet adhesive tape) for sealing of cartons. The wet adhesive tape is subjected to water coating treatment by a brush with good water absorption. The starch layer on the surface of the wet adhesive tape becomes sticky after water coating and can be adhered to the carton. In the carton sealing process, a specific electric machine is generally used to send out the wet adhesive tape after water coating, and then the wet adhesive tape after water coating is used for sealing treatment. However, the electric wet adhesive tape machine has poor flexibility, limited use conditions and high price, and is not suitable for use in the electric wet adhesive tape machine in the case of needing to carry out and use outside and small use amount.
[0004] There is also a manual wet adhesive tape machine on the market. The paper output mode of the manual wet adhesive tape machine is manual rolling of the rubber roller. The wet adhesive tape is sent to the brush outlet position by the rubber roller, and then manually pulled out for use. In the existing manual wet adhesive tape machine, the friction between the wet adhesive tape and the brush is large, the rigidity of the wet adhesive tape is weak, and the wet adhesive tape is easily bent inside the machine flow channel, which causes the wet adhesive tape to be pushed out, affecting the use performance. Moreover, when the wet adhesive tape is manually and quickly pulled, the wet adhesive tape will continue to move forward or rebound due to inertia, causing the wet adhesive tape to overshoot or reverse and fall off.
[0005] In addition, in the current manual wet adhesive tape machine, the opening depth of the brush head is 10 mm, and the opening effect is 1 / 4, that is, 4 branches are opened for a single brush wire. Currently, the rigidity of a single brush wire is strong at this opening depth and opening effect. The high rigidity will cause the pressure between the brush and the upper pressing plate to increase, which will cause the soft wet adhesive tape to not pass through, affecting the use performance.
[0006] Currently, whether it is an electric wet adhesive tape machine or a manual wet adhesive tape machine, the water in the water box is easy to splash out when the position is moved during carrying and use, which causes poor use experience and frequent water replenishment, affecting the use performance. INVENTION CONTENTS
[0007] The utility model aims to provide a machine for water coating and cutting of adhesive tape to solve at least one of the above technical problems.
[0008] According to one aspect of the utility model, a machine for water coating and cutting of adhesive tape is provided, which comprises:
[0009] a tape support assembly for carrying a wet adhesive tape roll;
[0010] a flow channel for limiting the up-and-down position of the wet adhesive tape, a free end of the wet adhesive tape roll on the tape support assembly being able to be inserted into the flow channel;
[0011] a rubber roller assembly for driving the wet adhesive tape to move in a downstream direction in the flow channel;
[0012] a cutter assembly for cutting the wet adhesive tape, the cutter assembly being arranged in a downstream direction of the flow channel; and
[0013] a water tank assembly arranged in a downstream direction of the cutter assembly, the water tank assembly comprising a brush capable of wetting the wet adhesive tape.
[0014] The machine for applying water to the adhesive tape and cutting the adhesive tape of the utility model loads the wet adhesive tape roll on the tape support assembly, manually feeds the wet adhesive tape into the flow channel, pushes the wet adhesive tape to the brush position after the wet adhesive tape passes through the flow channel through the rubber roller assembly, the bottom of the wet adhesive tape is the starch compound which sticks when meeting water, when the wet adhesive tape passes through the brush, the water droplets on the brush will be applied to the bottom of the wet adhesive tape, so that the wet adhesive tape appears sticky, and then the cutter assembly is used to cut the wet adhesive tape, so that the wet adhesive tape can be used for sealing the carton. Since the flow channel limits the up-and-down position of the wet adhesive tape, when the rubber roller assembly feeds the wet adhesive tape forward, the flow channel limits the wet adhesive tape within its range and prevents the wet adhesive tape from running out, so that the feeding smoothness of the wet adhesive tape is greatly increased, and the problem that the wet adhesive tape is bent in the machine due to large resistance and cannot be fed out is solved. The machine of the utility model has no power source, the overall machine cost is low, the machine is convenient to carry, and the machine can be used without power supply. In addition, the feeding of the wet adhesive tape is smooth, so that the probability of blockage of the wet adhesive tape in the machine is greatly reduced.
[0015] In some embodiments, a left side plate and a right side plate can also be included, the tape support assembly is arranged on the left side plate, and the flow channel, the rubber roller assembly, the cutter assembly and the water tank assembly are arranged between the left side plate and the right side plate. Thus, the left side plate and the right side plate are used to support and carry the tape support assembly, the flow channel, the rubber roller assembly, the cutter assembly and the water tank assembly.
[0016] In some embodiments, the adhesive tape supporting assembly can comprise a supporting roller and a connecting rod, one end of the connecting rod is hinged on the left side plate, the supporting roller is arranged on the other end of the connecting rod, both ends of the supporting roller can be respectively overlapped on the top of the left side plate and the top of the right side plate, a limiting post is arranged on the left side plate, an arc-shaped slot is arranged on the connecting rod, and the limiting post is accommodated in the arc-shaped slot to limit the swing angle of the connecting rod. Thus, when the wet adhesive tape roll needs to be installed, the supporting roller is lifted from the top of the left side plate and the top of the right side plate, and the supporting roller is inserted into the inner cylinder of the wet adhesive tape roll. Since both ends of the supporting roller can be respectively overlapped on the top of the left side plate and the top of the right side plate, when the radius of the wet adhesive tape roll becomes smaller, the wet adhesive tape roll on the supporting roller will not fall off, thereby ensuring the stability of operation. In addition, the limiting post can limit the swing angle of the connecting rod, so as to ensure that the supporting roller is always located above the left side plate and the right side plate when swinging, thereby preventing the equipment from tilting due to excessive swing of the supporting roller (the supporting roller swings to the area above the top of the left side plate and the top of the right side plate) when the wet adhesive tape roll is installed.
[0017] In some embodiments, two supporting rods and two damping plates can also be included,
[0018] One end of the supporting rod is arranged on the left side plate, and the other end of the supporting rod is arranged on the right side plate,
[0019] The first end of the damping plate is sleeved on one of the supporting rods, a locking bolt is arranged on the first end of the damping plate, and the end of the locking bolt can abut against the supporting rod,
[0020] The second end of the damping plate is overlapped on the other supporting rod,
[0021] When the adhesive tape supporting assembly carries the wet adhesive tape roll, the two damping plates are located on both sides of the wet adhesive tape roll.
[0022] Thus, when the wet adhesive tape roll is installed on the adhesive tape supporting assembly, the wet adhesive tape roll is located between the two damping plates. The locking bolt is loosened, the position of the damping plate on the supporting rod is adjusted, and the two damping plates are ensured to clamp the wet adhesive tape roll with a certain force. In this way, the two damping plates can increase the damping force of the wet adhesive tape roll. When the wet adhesive tape is manually and quickly pulled, the two damping plates can provide a larger damping force to the wet adhesive tape roll, so that the wet adhesive tape roll immediately stops rotating, and the overshoot or reverse falling phenomenon of the wet adhesive tape can be solved.
[0023] In some embodiments, the flow channel can include an upper flow channel plate and a lower flow channel plate arranged in an up-down manner, an end of the upper flow channel plate close to the adhesive tape supporting assembly is upwardly turned, an end of the lower flow channel plate close to the adhesive tape supporting assembly is downwardly turned, an end of the upper flow channel plate close to the cutter assembly is comb-shaped, and the end of the upper flow channel plate close to the cutter assembly is provided with a comb-shaped baffle arranged perpendicularly to the upper flow channel plate. Thus, the upper flow channel plate and the lower flow channel plate can jointly limit the position of the wet adhesive tape, and when the rubber roller assembly forwards the wet adhesive tape, the upper flow channel plate and the lower flow channel plate can limit the wet adhesive tape within the range between them and prevent the wet adhesive tape from running out, so that the outputting of the wet adhesive tape is greatly facilitated. When the water-coating surface of the wet adhesive tape roll faces the central position of the wet adhesive tape roll, the free end of the wet adhesive tape is transmitted into the flow channel from the end of the upper flow channel plate close to the adhesive tape supporting assembly, and the upwardly turned end of the upper flow channel plate can guide the transmission of the wet adhesive tape and prevent the end of the upper flow channel plate from cutting the wet adhesive tape. When the water-coating surface of the wet adhesive tape roll faces away from the central position of the wet adhesive tape roll, the free end of the wet adhesive tape is transmitted into the flow channel from the end of the lower flow channel plate close to the adhesive tape supporting assembly, and the downwardly turned end of the lower flow channel plate can guide the transmission of the wet adhesive tape and prevent the end of the lower flow channel plate from cutting the wet adhesive tape. The device is suitable for two types of wet adhesive tape rolls (a wet adhesive tape roll with the water-coating surface facing the central position of the wet adhesive tape roll and a wet adhesive tape roll with the water-coating surface facing away from the central position of the wet adhesive tape roll), the comb-shaped end of the upper flow channel plate close to the cutter assembly can effectively improve the problem of reduced rigidity caused by the lack of support of the wet adhesive tape between the outlet of the flow channel and the cutter assembly, prevent the wet adhesive tape from arching between the outlet of the flow channel and the cutter assembly, and thus ensure the smooth outputting of the wet adhesive tape and avoid the problem of bending of the wet adhesive tape caused by large resistance, and the comb-shaped baffle can prevent hands from being inserted and improve safety.
[0024] In some embodiments, the flow channel can include an upper flow channel plate and a lower flow channel plate arranged in an up-down manner, the rubber roller assembly includes an upper rubber roller, a lower rubber roller, a bearing rod, and a mounting frame,
[0025] The upper flow channel plate is provided with an upper accommodating groove, and the lower flow channel plate is provided with a lower accommodating groove, the upper accommodating groove and the lower accommodating groove are arranged in an up-down manner,
[0026] One end of the bearing rod is arranged on the left side plate, the other end of the bearing rod is arranged on the right side plate, the lower rubber roller is sleeved on the bearing rod and can rotate on the bearing rod, the top of the lower rubber roller is located in the lower accommodating groove or below the lower accommodating groove, and the highest point of the lower rubber roller is not higher than the upper surface of the lower flow channel plate,
[0027] The mounting frame is in a U shape as a whole, two free ends of the mounting frame are respectively hinged to the left side plate and the right side plate, the upper rubber roller is arranged on the mounting frame and can rotate on the mounting frame, the upper rubber roller is located in the upper accommodating groove, and the bottom of the upper rubber roller can be attached to the top of the lower rubber roller.
[0028] Thus, the flow channel upper plate and the flow channel lower plate can jointly limit the position of the wet water adhesive tape, and the flow channel upper plate and the flow channel lower plate can limit the wet water adhesive tape within the range between the two when the rubber roller assembly sends the wet water adhesive tape forward, so that the wet water adhesive tape can be sent out smoothly; when the wet water adhesive tape needs to be sent out, the upper rubber roller is pressed and the upper rubber roller is manually pushed to rotate at the same time, the pressing force between the upper rubber roller and the lower rubber roller is increased, and the wet water adhesive tape between the upper rubber roller and the lower rubber roller is pushed to the brush position for wet water treatment under the rotation of the upper rubber roller; after the sending out is completed, the upper rubber roller is loosened, and the upper rubber roller has a floating space upward because the two free ends of the mounting frame on which the upper rubber roller is mounted are respectively hinged on the left side plate and the right side plate, the pressing force between the upper rubber roller and the lower rubber roller is reduced, and the wet water adhesive tape between the upper rubber roller and the lower rubber roller stops being delivered to the brush direction; when the free end of the wet water adhesive tape needs to pass between the upper rubber roller and the lower rubber roller to enter the flow channel, the mounting frame can also be lifted upward to separate the upper rubber roller and the lower rubber roller.
[0029] In some embodiments, a reset spring can also be included, the cutting knife assembly includes a cutting knife and a U-shaped mounting frame, the middle positions of the two arms of the U-shaped mounting frame are respectively hinged on the left side plate and the right side plate, the cutting knife is arranged on the connecting arm of the U-shaped mounting frame, the cutting knife is arranged in the downstream direction of the flow channel, the cutting knife can cut the wet water adhesive tape sent out from the flow channel, one end of the reset spring is arranged on the free end of the U-shaped mounting frame, and the other end of the reset spring is fixed on the left side plate and / or the right side plate. Thus, when the wet water adhesive tape needs to be cut, the wet water adhesive tape can be cut by pressing the cutting knife downward, and after cutting, the cutting knife is loosened, and the cutting knife is lifted upward under the restoring force of the reset spring because the middle positions of the two arms of the U-shaped mounting frame are respectively hinged on the left side plate and the right side plate and the reset spring is arranged on the free end of the U-shaped mounting frame, so as to prepare for the next cutting of the wet water adhesive tape, and meanwhile, the normal delivery of the new wet water adhesive tape is not affected.
[0030] In some embodiments, a delivery flow channel can also be included, the delivery flow channel is arranged in the downstream direction of the cutting knife assembly, an upwardly turned pressing plate is arranged at the outlet of the delivery flow channel, and the pressing plate is located above the brush of the water tank assembly. Thus, the pressing plate can make the wet water adhesive tape fully contact with the brush, and ensure the water application effect of the brush on the wet water adhesive tape, when the rubber roller assembly sends the wet water adhesive tape to the brush position, the wet water adhesive tape will receive a relatively large resistance when passing through the brush, and the resistance is derived from the brush and the pressing plate, in order to ensure that the stiffness of the wet water adhesive tape can overcome the resistance, the delivery flow channel between the cutting knife assembly and the brush can effectively improve the stiffness reduction problem of the wet water adhesive tape caused by no support between the cutting knife assembly and the brush, so as to ensure that the wet water adhesive tape is sent out smoothly, and the problem that the wet water adhesive tape is bent and cannot be sent out due to the relatively large resistance can be avoided.
[0031] In some embodiments, the single brush filament of the brush can have a blooming depth of 20 mm, and the single brush filament of the brush can have 4 to 7 branches. Thus, the brush becomes softer and denser due to such design, and has stronger water absorption, ensuring the water application effect on the wet adhesive tape.
[0032] In some embodiments, the water tank assembly can further include a tank body, a tank cover and a fixing knob, the tank body is arranged between the left side plate and the right side plate, the tank body is transparent, the bottom of the brush is accommodated in the tank body, the top of the brush extends out of the opening at the top of the tank body and can wet the wet adhesive tape, the tank cover covers the area outside the brush at the opening at the top of the tank body, and the fixing knob is arranged in the left side plate and / or the right side plate and the free end of the fixing knob can press against the tank body. Thus, the tank cover is closed when the machine is used, and the water in the tank body will not splash out when the machine moves. The tank body is transparent, and the water level can be easily observed during use. When water needs to be added, the fixing knob is loosened, and the tank body is pulled out for water replenishment. Alternatively, the tank cover can be directly opened, and the water cup can be used to add water, which is convenient and flexible. BRIEF DESCRIPTION OF DRAWINGS

In addition, the terms "first", "second" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
[0042] Figures 1 to 6 The structure of the machine for applying water to adhesive tape and cutting is schematically shown.
[0043] Reference Figures 1 to 6 A machine for applying water to adhesive tape and cutting, comprising an adhesive tape supporting assembly 1, a flow channel 2, an adhesive roller assembly, a cutter assembly 4 and a water tank assembly 5. In addition, the machine for applying water to adhesive tape and cutting can further comprise a left side plate 6, a right side plate 7, a supporting rod 8, a damping plate 9, a return spring 10 and an outflow channel 110.
[0044] Reference Figure 1 And Figure 2 The left side plate 6 and the right side plate 7 are arranged in parallel, and the adhesive tape supporting assembly 1, the flow channel 2, the adhesive roller assembly, the cutter assembly 4, the water tank assembly 5, the supporting rod 8, the damping plate 9, the return spring 10 and the outflow channel 110 are all installed between the left side plate 6 and the right side plate 7, and the left side plate 6 and the right side plate 6 are used to support and carry the adhesive tape supporting assembly 1, the flow channel 2, the adhesive roller assembly, the cutter assembly 4, the water tank assembly 5, the supporting rod 8, the damping plate 9, the return spring 10 and the outflow channel 110.
[0045] In order to reduce the cost of the left side plate 6 and the right side plate 7 and not affect the performance, appearance and weight, optimization needs to be carried out on the processing technology, and the scheme adopted in the embodiment is as follows: first, use the film-coated sand process to make the blank material of the left side plate 6 and the right side plate 7, then use machining to trim the edges, and finally punch, press and spray, at this time the cost of the whole machine can be reduced by 110%.
[0046] The adhesive tape supporting assembly 1 is used to carry wet water adhesive tape, that is, the wet water adhesive tape roll is installed on the adhesive tape supporting assembly 1, and reference Figures 1 to 3 , Figure 5The tape support assembly 1 includes a support roller 11 and a connecting rod 12, one end of the connecting rod 12 ( Figure 5 The right end of the connecting rod 12 is hinged to the left side plate 6, allowing the connecting rod 12 to swing on the left side plate 6. The support roller 11 is fixed to the other end of the connecting rod 12. Figure 5 On the left end of the connecting rod 12, the two ends of the support roller 11 can respectively overlap the top of the left side plate 6 and the top of the right side plate 7. An arc-shaped groove can be formed at the corresponding position on the top of the left side plate 6 and the right side plate 7. When the two ends of the support roller 11 overlap the top of the left side plate 6 and the top of the right side plate 7 respectively, the two ends of the support roller 11 are respectively accommodated in the arc-shaped grooves on the top of the left side plate 6 and the top of the right side plate 7. The arc-shaped grooves can limit the two ends of the support roller 11 and also increase the contact area between the support roller 11 and the left side plate 6 and the right side plate 7, preventing the tops of the left side plate 6 and the right side plate 7 from being deformed by the support roller 11 and the wet tape roll. A limit post 61 is installed on the left side plate 6, and one end of the connecting rod 12 ( Figure 5 The right end of the connecting rod 12 is fan-shaped, and an arc groove 121 is formed at the end of the fan-shaped connecting rod 12. The limiting post 61 is accommodated in the arc groove 121, and the limiting post 61 can limit the swing angle of the connecting rod 12. When it is necessary to install the wet tape roll, the support roller 11 is lifted from the top of the left side plate 6 and the right side plate 7, and the support roller 11 is inserted into the inner cylinder of the wet tape roll. Since the two ends of the support roller 11 can overlap the top of the left side plate 6 and the top of the right side plate 7 respectively, the wet tape roll on the support roller 11 will not fall off when the radius of the wet tape roll becomes smaller, thus ensuring the stability of operation. In addition, the limiting post 61 can limit the swing angle of the connecting rod 12, ensuring that the support roller 11 is always above the left side plate 6 and the right side plate 7 when swinging, preventing the support roller 11 from swinging too much (the support roller 11 swings to an area outside the top of the left side plate 6 and the right side plate 7) when installing the wet tape roll. Figure 5 The right side of the left side plate 6 and the right side plate 7 caused the equipment to tilt and tip over.
[0047] See Figures 1 to 3 , Figure 5 There are two support rods 8 and two damping plates 9. One end of each support rod 8 is fixed to the left side plate 6, and the other end of each support rod 8 is fixed to the right side plate 7. The two support rods 8 are arranged in parallel, with one support rod 8 located at the end of the left side plate 6 and the other support rod 8 located in the middle of the left side plate 6. One end of the connecting rod 12 ( Figure 5 The right end of the connecting rod 12 is fitted onto a support rod 8. A limiting ring can be installed on the support rod 8 to limit the connecting rod 12 along the length of the support rod 8, preventing the connecting rod 12 from sliding along the support rod 8. The connecting rod 12 can swing around the support rod 8; the first ends of the two damping plates 9 (Figure 3 The first ends of the two damping plates 9 are hooked, and the first ends of the two damping plates 9 are respectively provided with locking bolts 91, the ends of the locking bolts 91 can be pressed on the support rod 8, the second ends of the two damping plates 9 are overlapped on the other support rod 8, Figure 3 The left ends of the two damping plates 9 are overlapped on the other support rod 8, when the wet water adhesive tape roll is loaded on the support roller 11 of the adhesive tape supporting assembly 1, the two damping plates 9 are respectively located on the two sides of the wet water adhesive tape roll, when the wet water adhesive tape roll is installed on the support roller 11 of the adhesive tape supporting assembly 1, the wet water adhesive tape roll is located between the two damping plates 9, the locking bolts 91 are loosened, the positions of the damping plates 9 on the support rod 8 are adjusted, and the two damping plates 9 are ensured to clamp the wet water adhesive tape roll with a certain force, so that the two damping plates 9 can increase the damping force of the wet water adhesive tape roll, when the wet water adhesive tape is manually and quickly pulled, the two damping plates 9 can give the wet water adhesive tape roll a larger damping force, so that the wet water adhesive tape roll is immediately stopped, and the overshoot or reverse falling phenomenon of the wet water adhesive tape can be solved.
[0048] The free end of the wet water adhesive tape roll on the support roller 11 of the adhesive tape supporting assembly 1 can be inserted into the flow channel 2, and the flow channel 2 can limit the up-down position of the wet water adhesive tape. The specific structure of the flow channel 2 is as follows: Figure 1 、 Figure 3 and Figure 4 The flow channel 2 includes the flow channel upper plate 21 and the flow channel lower plate 22 arranged in the up-down direction, the end of the flow channel upper plate 21 close to the support roller 11 of the adhesive tape supporting assembly 1 is upturned, the end of the flow channel lower plate 22 close to the support roller 11 of the adhesive tape supporting assembly 1 is downturned, the flow channel upper plate 21 and the flow channel lower plate 22 can jointly limit the up-down position of the wet water adhesive tape, the flow channel upper plate 21 and the flow channel lower plate 22 can limit the wet water adhesive tape within the range between them and prevent the wet water adhesive tape from running out, so that the discharging smoothness of the wet water adhesive tape is greatly increased; when the water-coating surface of the wet water adhesive tape roll faces the central position of the wet water adhesive tape roll, the free end of the wet water adhesive tape is transmitted from the end of the flow channel upper plate 21 close to the support roller 11 into the flow channel 2, and the upturned end of the flow channel upper plate 21 can guide the conveying of the wet water adhesive tape and prevent the end of the flow channel upper plate 21 from cutting the wet water adhesive tape; when the water-coating surface of the wet water adhesive tape roll faces away from the central position of the wet water adhesive tape roll, the free end of the wet water adhesive tape can first pass over the support rod 8 from above the support rod 8, and then be transmitted from the end of the flow channel lower plate 22 close to the support roller 11 into the flow channel 2, and the downturned end of the flow channel lower plate 22 can guide the conveying of the wet water adhesive tape and prevent the end of the flow channel lower plate 22 from cutting the wet water adhesive tape, which is suitable for two types of wet water adhesive tape rolls (the wet water adhesive tape roll with the water-coating surface facing the central position of the wet water adhesive tape roll and the wet water adhesive tape roll with the water-coating surface facing away from the central position of the wet water adhesive tape roll).
[0049] refer to Figures 1 to 4 The end of the upper flow channel plate 21 near the cutter assembly 4 is comb-shaped. A comb-shaped baffle 211, perpendicular to the upper flow channel plate 21, is provided at this end. This comb-shaped design effectively improves the rigidity of the wet tape due to the lack of support between the outlet of the flow channel 2 and the cutter assembly 4, preventing the wet tape from arching between them. This ensures smooth tape output and avoids the problem of the wet tape bending and failing to be fed due to high resistance. The comb-shaped baffle 211 also prevents hands from entering, improving safety. (Reference) Figure 4 The comb-shaped baffle 211 and the comb-shaped end of the upper flow channel plate 21 near the cutter assembly 4 can be integrally formed. A square wave hollow pattern is first cut at the end of the upper flow channel plate 21, and then the end of the upper flow channel plate 21 is bent at 90 degrees to form the comb. Figure 4 The style of the end of the upper plate 21 of the middle channel can reduce the processing and installation costs. Of course, the comb-shaped baffle 211 and the comb-shaped end of the upper plate 21 near the cutter assembly 4 can also be two solid plates. In this case, the comb-shaped baffle 211 needs to be installed (e.g., welded) on the upper plate 21 of the middle channel.
[0050] The rubber roller assembly can drive the wet conveyor belt to move downstream in channel 2, specifically, refer to Figures 1 to 4 The rubber roller assembly includes an upper rubber roller 31, a lower rubber roller 32, a support rod 33, and a mounting bracket 34. An upper receiving groove 212 is formed in the middle of the upper flow channel plate 21, and a lower receiving groove 221 is formed in the middle of the lower flow channel plate 22. The upper receiving groove 212 and the lower receiving groove 221 are arranged vertically. One end of the support rod 33 is fixed to the left side plate 6, and the other end is fixed to the right side plate 7. The lower rubber roller 32 is fitted onto the support rod 33 and can rotate on the support rod 33. The lower rubber roller 32 can be mounted on the support rod 33 via a bearing. In this embodiment, the top of the lower rubber roller 32 is located below the lower receiving groove 221. Preferably, [reference needed]. Figure 3 The top of the lower roller 32 is flush with the lower surface of the flow channel lower plate 22. In other embodiments, the top of the lower roller 32 may also be located in the lower receiving groove 221, ensuring that the highest point of the lower roller 32 is not higher than the upper surface of the flow channel lower plate 22. The mounting bracket 34 is generally U-shaped, and its two free ends are respectively hinged to the left side plate 6 and the right side plate 7. (Refer to...) Figure 2The two free ends of the mounting frame 34 are respectively mounted on the left side plate 6 and the right side plate 7 via a mounting shaft 4212. The two free ends of the mounting frame 34 can rotate on the mounting shaft 4212. The upper glue roller 31 is mounted on the mounting frame 34 and can rotate on the mounting frame 34. The mounting frame 34 can be composed of two symmetrically arranged L-shaped frames. One end of the two frames is respectively mounted on the left side plate 6 and the right side plate 7 via a mounting shaft 4212. The upper glue roller 31 can be mounted between the other ends of the two frames via a shaft. The upper glue roller 31 can rotate between the two frames. The upper glue roller 31 is located in the upper receiving groove 212. The lowest point of the upper glue roller 31 is lower than the lower surface of the horizontal section of the upper flow channel plate 21. (Reference) Figure 3 Under normal conditions, the bottom of the upper rubber roller 31 adheres to the top of the lower rubber roller 32 under the influence of gravity. When material needs to be discharged, press the upper rubber roller 31 and simultaneously manually push it to rotate. The pressure between the upper rubber roller 31 and the lower rubber roller 32 increases. Under the rotation of the upper rubber roller 31, the wet tape between the upper rubber roller 31 and the lower rubber roller 32 is pushed to the position of the brush 51 for wetting treatment under the combined action of the upper rubber roller 31 and the lower rubber roller 32 rotating in opposite directions. After the material is discharged, release the brush. The upper rubber roller 31, because its two free ends are hinged to the left side plate 6 and the right side plate 7 respectively, has room to float upwards. This reduces the pressure between the upper rubber roller 31 and the lower rubber roller 32, stopping the wet tape between them from being conveyed towards the brush 51. When it is necessary to pass the free end of the wet tape between the upper and lower rubber rollers 31 and into the flow channel 2, the mounting frame 34 can be lifted upwards to separate the upper and lower rubber rollers 31 and 32. In this embodiment, the surfaces of both the upper and lower rubber rollers 31 and 32 are covered with a layer of rubber or other soft rubber to increase friction with the wet tape. In other embodiments, either the upper or lower rubber roller 32 can be replaced with a bearing.

Figure 3 The cutter 41 can cut the wet adhesive tape sent out from the flow channel 2 on the left side of the middle flow channel 2. The number of the return springs 10 is two, and one end of each of the two return springs 10 is fixed to the free end of each of the two arms 421 of the U-shaped mounting frame 42, and the other end of each of the two return springs 10 is fixed to the left side plate 6 and the right side plate 7. When it is necessary to cut the wet adhesive tape, the wet adhesive tape can be cut by pressing the cutter 41 downward. After cutting, the cutter 41 is released, and the cutter 41 will be lifted upward under the restoring force of the return springs 10 because the middle positions of the two arms 421 of the U-shaped mounting frame 42 are respectively hinged to the left side plate 6 and the right side plate 7 and the free ends of the two arms 421 of the U-shaped mounting frame 42 are provided with the return springs 10, so as to prepare for the next cutting of the wet adhesive tape and will not affect the normal conveying of the new wet adhesive tape.
[0052] Referring to Figure 1 , Figure 2 and Figure 6 , the middle positions of the two arms 421 of the U-shaped mounting frame 42 are respectively formed with flanges 4211, the mounting frame 34 is located between the two arms 421 of the U-shaped mounting frame 42, and the two L-shaped frame bodies of the mounting frame 34 are respectively located below the two flanges 4211. The flanges 4211 can limit the upward swinging of the mounting frame 34, and when it is necessary to pass the free end of the wet adhesive tape through the upper glue roller 31 and the lower glue roller 32 and through the cutter 41, the mounting frame 34 is lifted upward, and the mounting frame 34 can drive the U-shaped mounting frame 42 to be lifted together through the flanges 4211, which is very convenient.
[0053] Referring to Figure 3 , a sub-cutter 411 can be installed below the end of the flow channel lower plate 22 close to the cutter 41 to carry the wet adhesive tape. When the cutter 41 moves downward, the wet adhesive tape below the cutter 41 can be quickly cut off. The cutter 41 can use a flat cutter for cutting or a toothed cutter for cutting.

The pressing plate 111 can make the wet water tape fully contact with the brush 51, and ensure the water application effect of the brush 51 on the wet water tape. When the wet water tape is sent to the position of the brush 51 by the rubber roller assembly 1, the wet water tape will be subjected to a relatively large resistance when passing through the brush 51, which is caused by the brush 51 and the pressing plate 111. In order to ensure that the rigidity of the wet water tape can overcome the resistance, the discharge flow channel 110 between the cutter 41 of the cutter assembly 4 and the brush 51 can effectively improve the rigidity reduction problem of the wet water tape caused by the lack of support between the cutter 41 and the brush 51, so as to ensure that the wet water tape can be smoothly sent out, and the problem that the wet water tape is bent and cannot be sent out due to the relatively large resistance can be avoided. In addition, the height of the outlet (the port close to the brush 51) of the discharge flow channel 110 is 1 mm, which can further ensure that the wet water tape can be smoothly sent out, and the problem that the wet water tape is bent and cannot be sent out due to the relatively large resistance can be avoided.
