Description

Technical Field

[0001] This utility model relates to the field of tissue paper production technology, and more specifically, it relates to a noise reduction mechanism on a folding wet wipe machine. Background Technology

[0002] Wet wipes are products made from non-woven fabrics, woven fabrics, dust-free paper or other raw materials, using purified water as production water, and adding appropriate amounts of preservatives and other auxiliary materials. They have a cleaning effect on hands, skin, mucous membranes or object surfaces.

[0003] For example, the patent announcement number CN218537245U discloses a slicing and folding machine for wet wipe production. Through the setting of a fixed frame, mounting box, nozzle, disinfection structure, fan, flipping plate and cleaning brush, the slicing and folding machine can automatically clean the dust and bacteria attached to its own conveyor belt surface. There is no need for workers to disinfect the equipment before production, which reduces the labor burden of workers and effectively improves the production quality of wet wipes, preventing external dust or bacteria from contaminating the wet wipes.

[0004] While the above method solves the problem of dust and bacteria easily adhering to the conveyor belt surface of existing slicing and folding machines, thus contaminating the wipes, the equipment requires a motor as a power source, and the motor operation generates significant noise, affecting the operator's work experience and causing inconvenience to the staff. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a noise reduction mechanism for a folding wet wipe machine that can reduce noise pollution.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A noise reduction mechanism for a folding wet wipe machine includes a worktable and a motor positioned above the worktable. Two slots are formed on the upper surface of the worktable, with each slot located on either side of the motor. A noise reduction cover is slidably connected within the slots, and a mounting slot for embedding the motor is provided inside the noise reduction cover.

[0008] The silencer includes a housing and a base fixedly connected to the housing. The base is placed in a slot. A cavity is formed inside the silencer, and a guide hole communicating with the cavity is formed on the side wall of the silencer. A silencer pipe connected to the guide hole is provided inside the cavity. The silencer pipe has a corrugated cross-section.

[0009] A vacuum groove is provided on the outside of the cavity, and the vacuum groove is in a vacuum state. A cavity is provided on one side of the vacuum groove, and the cavity is filled with sound-absorbing cotton.

[0010] A sealing cover is provided between the two soundproof covers.

[0011] The present invention is further configured such that: a spring is provided on one side of the slot, the spring is fixedly connected to the inner wall of the slot, and a pressing plate is fixedly connected to the other end of the spring; the side wall of the pressing plate abuts against the base, and an anti-slip pad is provided on the end face of the pressing plate.

[0012] The present invention is further configured such that: a card block for blocking the base is provided on the card slot, a magnetic sheet one is provided on the side wall of the base, and a magnetic sheet two is provided on the inner wall of the card slot, and the magnetic sheet one and the magnetic sheet two are magnetically attracted to each other.

[0013] The present invention is further configured such that: the sealing cover includes a cover body and a rod body, the outer peripheral wall of the rod body is provided with threads, the inner wall of the soundproof cover is provided with threads corresponding to the rod body, and the rod body and the soundproof cover are connected by threads.

[0014] The present invention is further configured such that a vacuum groove is provided inside the cover body.

[0015] The present invention is further configured such that the inner wall of the soundproof cover is provided with a plurality of soundproofing holes.

[0016] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows:

[0017] By adding a silencer cover to the outside of the motor, the noise generated during the motor's operation comes into contact with the silencer cover, enters the guide hole, and then passes through the silencer pipe. Since the silencer pipe is wavy, it facilitates the noise to travel the longest distance during transmission for attenuation. Since sound cannot travel in a vacuum, it can be attenuated through a vacuum groove. Furthermore, the sound enters the cavity through the silencer hole, which facilitates the cavity's absorption of the sound. Moreover, the sealing cover can prevent noise leakage, thus increasing the attenuation effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Working principle: Before use, place one end of the base 7 against the extrusion plate 15 to compress the spring 14, causing it to deform. Then, place the other end of the base 7 into the slot 3, and magnetically attract the magnetic piece 16 and magnetic piece 17 to complete the installation. Finally, repeat the above steps to install the second muffler 4. Then, place the sealing cover 13 between the two mufflers 4 to connect the sealing cover 13 and the muffler 4.

[0023] When the motor 2 is working, the sound enters the cavity 8 through the guide hole 9 and the silencer hole 21. The sound entering through the guide hole 9 will enter the silencer tube 10. Since the path inside the silencer tube 10 is relatively long, the sound will be absorbed during the transmission process. The sound passing through the silencer tube 10 will be further absorbed by the vacuum tank 11 and the sound-absorbing cotton.

[0024] The sound entering the cavity 8 through the silencing hole 21 will first come into contact with the outer wall of the silencing tube 10 and cancel out the sound inside the silencing tube 10. It will also be further absorbed by the vacuum groove 11 and the silencing cotton.

[0025] Sound traveling upwards will be absorbed by vacuum tank 20.
