Description

Technical Field

[0001] The utility model relates to the field of cutting and packaging, in particular to a water volume regulating device of an automatic tape wetting machine. Background Art

[0002] The tape wetting machine is an automated device that seals boxes by wetting the adhesive surface of the tape. During operation, the machine wets the kraft paper tape and then sticks it on the carton interface, forming a strong and environmentally friendly seal.

[0003] Existing tape wetting machines generally include a water supply device, a paper feeding device and a cutting device. A closed upper water tank supplies water to a water tank below through a water pipe. Since the tape outlet is located above the water tank and a water-absorbing sponge is provided at the outlet, when the tape is output, its adhesive surface is wetted and becomes sticky when passing through the water-absorbing sponge.

[0004] The height of the water level in the water tank determines the amount of water absorbed by the absorbent sponge. In actual applications, different tapes have different requirements for the amount of water they absorb (some are large, some are small, and too large or too small will affect the sealing effect). In addition, the output speed of the tape is also different. The faster the speed, the greater the amount of water required to be absorbed. However, the water level of the water tank of the existing wetting machine is fixed, which cannot meet the requirements of different amounts of water, resulting in unsatisfactory water absorption of the tape and poor tape adhesion. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a water volume regulating device for an automatic tape wetting machine, aiming to solve the problem that the water level in the water tank of the current wetting machine is fixed and cannot meet the different requirements of the wetting volume of different tapes, resulting in unsatisfactory water absorption effect of the tape and poor bonding effect.

[0034] See also Figure 1-Figure 7 , which is a schematic structural diagram of a water volume regulating device of an automatic tape wetting machine provided in one embodiment of the utility model, wherein the water volume regulating device of the automatic tape wetting machine comprises a water tank 100 provided at the tape outlet, a water tank 200 overlapped with the water tank 100, and a water outlet mechanism 300 provided on the water tank 200, wherein:

[0035] In order to supply water to the water tank 100 and to make the water level in the water tank 100 able to supply water to the water-absorbing sponge, the water tank 200 is arranged on one side of the tape outlet, and the water tank 100 is arranged transversely and perpendicularly to the outlet. The water tank 200 is overlapped at one end of the water tank 100, and includes a box body 210, an adjustment slope 220 arranged at the bottom of the box body 210, and a water outlet 230, so that the water in the water tank 200 flows from the water outlet 230 into the water tank 100 due to gravity.

[0036] With the adsorption of the water-absorbing sponge, the water level in the water tank 100 gradually decreases. In order to adjust the water level in the water tank 100 for the water-absorbing sponge to absorb, a water outlet mechanism 300 is provided at the water outlet 230 to control the water level. The water outlet mechanism 300 includes a box cover 310 movably connected to the water outlet 230, a sealing assembly 320 and a supporting assembly 330 provided in the box cover 310, and an elastic member 340 is also provided between the sealing assembly 320 and the supporting assembly 330. In order to allow the water in the water tank 200 to flow into the water tank 100, a through hole 311 is also provided at the center of the box cover 310. In order to facilitate disassembly and sealing, the inner circumference of the box cover 310 in this embodiment is provided with an internal thread for screwing with the water outlet 230 of the water tank 200.

[0037] Furthermore, in order to realize the water level adjustment function, a sealing assembly 320 and a supporting assembly 330 are provided in the box cover 310. The sealing assembly 320 includes a sealing ring 321 provided at the inner bottom of the box cover 310, and a sealing sheet 322 provided at the inner circle of the sealing ring 321. The outer periphery of the sealing ring 321 abuts against the inner wall of the box cover 310, and the sealing sheet 322 is embedded in the inner circle of the sealing ring 321 to seal the through hole 311 at the center of the box cover 310. It should be emphasized that the diameter of the sealing sheet 322 is greater than the diameter of the through hole 311, and the thickness of the sealing ring 321 is equal to the thickness of the sealing sheet 322, so that the supporting assembly 330 directly abuts against the end face of the sealing ring 321.

[0038] Since an elastic member 340 is provided between the sealing assembly 320 and the supporting assembly 330, in order to provide support to the sealing assembly 320, one end of the elastic member 340 abuts against the end surface of the sealing sheet 322, and the other end abuts against the supporting assembly 330. The supporting assembly 330 includes a limiting ring 331, and a supporting member 332 engaged with the limiting ring 331, one end of the supporting member 332 is inserted into the water outlet 230, and is used to abut against one end of the elastic member 340 away from the sealing sheet 322. The limiting ring 331 is superimposed on the sealing ring 321, and in order to avoid position interference, the inner diameter of the limiting ring 331 is larger than the inner diameter of the sealing ring 321, so as to leave an annular space in the limiting ring 331 for placing the supporting member 332.

[0039] Furthermore, the support member 332 includes a support portion 333 penetrating the water inlet and outlet 230, a limit portion 334 engaged with the limit ring 331, and a connecting inclined surface 335 connecting the support portion 333 and the limit portion 334, the two ends of the connecting inclined surface 335 are respectively connected to the outer periphery of the support portion 333 and the inner periphery of the limit portion 334, and the end face of the limit portion 334 is arranged at the end face of the water outlet 230. The inner diameter of the limit portion 334 is not less than the inner diameter of the sealing ring 321, so that the inner periphery of the limit portion 334 is at least flush with the inner periphery of the sealing ring 321, or the projection of the inner periphery of the limit portion 334 is directly mapped to the end face of the sealing ring 321. The diameter of the abutting portion 333 is smaller than the diameter of the water outlet 230, and the inner diameter of the limiting portion 334 is equal to the diameter of the water outlet 230, so that when the abutting portion 333 passes through the water inlet and outlet 230, the end surface of the limiting portion 334 abuts against the end surface of the water outlet 230 to prevent the support member 332 from falling into the water tank 200. At the same time, due to the screw connection between the tank cover 310 and the water outlet 230, the end surface of the limiting portion 334 of the support member 332 is pressed against the end surface of the water outlet 230, and then the support member 332 is set between the tank cover 310 and the water outlet 230.

[0040] It is worth noting that after the water tank 200 is installed, one end of the water tank 200 with the tank cover 310 overlaps the water tank 100, and a top column 110 is provided in the water tank 100, and its position is directly opposite to the through hole 311 of the tank cover 310. The top column 110 penetrates into the tank cover 310 and abuts against the end surface of the sealing piece 322 away from the elastic member 340. Since the bottom of the water tank 200 is also provided with an adjustment slope 220, it is only necessary to provide a lever on the automatic tape wetting machine, and by moving the lever, the height of the water tank 200 can be adjusted, and then the length of the top column 110 penetrating into the tank cover 310 can be adjusted. In this embodiment, the lever and the adjustment slope 220 overlap to adjust the height is a prior art, so it is not described in detail.

[0041] More importantly, after adjusting the height of the water tank 200, the length of the top column 110 penetrating the tank cover 310 becomes deeper and deeper, which lifts up the sealing piece 322. Since the outer diameter of the sealing piece 322 is smaller than the inner diameter of the limiting portion 334, the sealing piece 322 is able to move up and down in the support member 332 through the abutment of the top column 110. In addition, the elastic member 340 provided between the abutment portion 333 and the sealing piece 322 also provides a certain elastic support for the sealing piece 322 for resetting the sealing member. Since a plurality of water inlet grooves 336100 are arranged on the connecting inclined surface 335, when the sealing piece 322 is lifted up, the water in the water tank 200 enters from the water inlet grooves 336100, and flows into the gap between the sealing piece 322 and the through hole 311 to enter the water tank 100, thereby realizing the water level adjustment function.

[0042] In summary, according to the water volume regulating device of the automatic tape wetting machine proposed by the utility model, an elastic member is provided inside the box cover to connect the sealing component and the supporting component, and the height of the water tank is adjusted, thereby adjusting the height of the sealing component lifted by the top column, so that the water in the water tank enters the water tank through the gap between the raised sealing component and the through hole, thereby achieving the purpose of adjusting the water level in the water tank, ensuring the water absorption of the water-absorbing sponge and the water wetting effect of the tape, thereby maintaining the adhesive performance of the tape. Specifically, the water tank includes a box body, an adjusting slope and a water outlet provided on the box body; the water outlet mechanism includes a box cover, a sealing component and a supporting component provided in the box cover, and an elastic member is further provided between the sealing component and the supporting component, and the elastic member provides support for the sealing component. The top column in the water tank is inserted into the box cover, and the height of the water tank is adjusted so that the top column lifts the sealing component, so that the water in the water tank flows into the water tank through the gap between the sealing component and the through hole, thereby adjusting the water level in the water tank.
