Description

Technical Field

[0001] The utility model belongs to the technical field of noise reduction of tunnel washers, and in particular relates to a noise reduction device for tunnel washers. Background Art

[0002] Tunnel washing machines, often referred to as "tunnel washers," utilize water circulation and filtration technologies, significantly reducing water and steam consumption compared to traditional washing machines. These machines are enormous and can handle a variety of laundry processes, including pre-wash, main wash, rinsing, and neutralization. They offer superior overall performance and exceptional reliability. However, during the washing process, collisions between clothing and the washing structure and inner walls generate high-frequency vibrations, producing significant noise that can seriously impact worker health. Therefore, suitable noise reduction equipment is required.

[0003] For example, patent application number CN202222712267.6 discloses a noise reduction device for a tunnel washer, comprising a tunnel washer body, a feed port, a discharge port, and a discharge plate. The outer wall of the tunnel washer body is fixedly sleeved with a noise reduction device, a filter plate is fixedly installed on the inner wall on the right side of the feed port, a fan is fixedly connected to the right side of the feed port, a dust reduction bin is fixedly installed on the end of the fan away from the feed port, nozzles are evenly distributed above the interior of the dust reduction bin, and a water storage bin is fixedly installed on the lower end face of the dust reduction bin. The utility model achieves a sound-absorbing effect on the tunnel washer body by coordinating the tunnel washer body, the noise reduction device, the feed port, and the discharge port, and utilizing the setting of the noise reduction device. This effectively solves the problem of noise generated by contact between fabric and the inner wall of the tunnel washer body. The noise is absorbed by sound-absorbing cotton to reduce the noise generated by the tunnel washer body during operation, thereby achieving the noise reduction effect of the tunnel washer body.

[0004] In the existing technology, noise reduction is achieved by installing a noise reduction device on the outer wall of the tunnel washer to absorb the noise generated by the equipment. However, the overall device is only a temporary solution and still has many problems in use:

[0005] First, the reason tunnel washers generate a lot of noise is that the overall supporting and fixing equipment is not stable enough, causing the tunnel washer to vibrate a lot. This vibration causes various components to produce high-frequency noise. Simply placing sound-absorbing cotton on the outside can only temporarily alleviate the noise and cannot be used for a long time.

[0006] Secondly, the overall size of the tunnel washer varies greatly at different locations, and the existing support structure cannot be adjusted in time according to the different sizes, resulting in certain deficiencies in the practicality of the support structure. Utility Model Content

[0007] To overcome the shortcomings of the prior art, the present invention provides a noise reduction device for a tunnel washer. By utilizing a bracket and anti-slip pad, as well as a telescopic cylinder and shock-absorbing assembly, the device stably clamps and secures the exterior of the tunnel washer. Vibrations generated during operation are promptly absorbed, reducing and absorbing noise. This effectively improves noise reduction and is suitable for supporting and securing tunnel washers of varying sizes, significantly enhancing overall practicality.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a noise reduction device for a tunnel washer, comprising two brackets arranged opposite each other in an L-shape, wherein a telescopic cylinder is fixedly mounted on the end surface of one of the brackets, a telescopic rod is slidably connected within the telescopic cylinder, and the other end of the telescopic rod is connected to the end surface of the other bracket. A mounting groove is provided on the upper end surface of the bracket, wherein a non-slip pad, a sound-absorbing pad, and a second shock-absorbing pad are sequentially arranged in the mounting groove from top to bottom. The bent top end surfaces of the two brackets are provided with fixing bosses, and a detachable sound-absorbing band is disposed between the two fixing bosses. The sound-absorbing band is made of a flexible sound-absorbing cotton material. Below the sound-absorbing bands, multiple clamping frames are disposed on the outer end surface of the bracket, and each clamping frame has a shock-absorbing assembly. By providing the non-slip pad, the sound-absorbing pad, the second shock-absorbing pad, and the sound-absorbing band, the device can stably support and fix the entire tunnel washer, and vibrations generated during operation can be promptly absorbed, thereby reducing noise generation and absorbing noise, thereby effectively improving noise reduction quality.

[0009] Optionally, a plurality of support seats are provided on the bottom end surface of the bracket, and a first shock-absorbing pad is provided on the bottom end surface of the support seat. The provision of the first shock-absorbing pad reduces vibration transmission and vibration collision between the device and the ground, thereby further reducing noise generation.

[0010] Optionally, the fixing boss has a fixing groove formed on its end surface, into which a connecting block is fixedly connected via a bolt or screw hole. The sound-absorbing tape is fixedly connected to the upper end surfaces of two opposing connecting blocks. The arrangement of the connecting block and the fixing groove allows the sound-absorbing tape to be effectively wrapped and adhered to various parts of the tunnel washer exterior, thereby enhancing the noise absorption effect.

[0011] Optionally, the shock-absorbing assembly includes a slide bar slidably disposed within the clamping frame, one end of the slide bar extending above the anti-slip pad, a clamping plate connected to the end of the slide bar extending above the anti-slip pad, and a buffer block abutting against the other end of the slide bar within the clamping frame. The clamping plate and buffer block effectively clamp and secure the two side walls of the tunnel washer while also absorbing any vibrations that may be generated.

[0012] Optionally, the shock absorbing assembly further comprises a hard core block disposed inside the buffer block. The provision of the hard core block effectively increases the supporting and clamping pressure of the buffer block.

[0013] Optionally, the shock-absorbing assembly further includes a cover plate disposed on the upper end surface of the buffer block, the cover plate end surface being provided with a detector, the detector end being connected to the cover plate end surface. The detector arrangement allows for timely notification of external personnel for inspection and maintenance when vibration exceeds a specified level after clamping, thereby ensuring effective noise reduction.

[0014] Optionally, the shock absorbing assembly further comprises a pad abutting against one side of the buffer block in the clamping frame. The provision of the pad enables the clamping pressure of the clamping plate to be adjusted quickly.

[0015] Optionally, a limit slider is provided on the inner wall of the telescopic cylinder, and a matching limit slot is provided on the outer side of the limit slider on the corresponding end surface of the telescopic rod. The end surfaces of the telescopic rod and the telescopic cylinder are provided with multiple fixing holes. The provision of the limit slider and the limit slot effectively improves the connection strength between the telescopic cylinder and the telescopic rod.

[0016] In summary, compared with the prior art, the beneficial effects of this solution are:

[0017] (1) The utility model provides a stable support and fixation treatment for the whole tunnel washer by means of the arrangement of the bracket, the anti-skid pad, the sound-absorbing wrapping tape and the shock-absorbing assembly, thereby reducing the vibration of the whole tunnel washer during operation and absorbing the noise generated by the vibration, thereby effectively achieving the purpose of noise reduction, ensuring a good working environment and reducing the possibility of physical damage to workers;

[0018] (2) The utility model uses the buffer block and hard core block as well as the detector and pad to enable the shock-absorbing assembly to timely detect the vibration generated by the tunnel washer during operation and remind the staff to perform maintenance and inspection when the vibration increases abnormally. During the inspection and repair, only the pad or buffer block needs to be replaced to complete the inspection and repair. The maintenance is simple and the overall shock-absorbing quality can be guaranteed, thereby ensuring the noise reduction quality.

[0019] (3) The present invention adopts the arrangement of telescopic cylinder, telescopic rod and sound-absorbing wrapping tape made of flexible material, so that the device can support and fix the positions of different sizes of the washing tunnel and reduce noise, thereby effectively improving the practicality of the device.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] Example 1:

[0035] Reference Attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 7 A noise reduction device for a tunnel washer is provided. The device is used to support and reduce noise in a tunnel washer, i.e., a tunnel-type washing machine. Noise reduction is achieved by stably supporting and fixing the tunnel washer and absorbing vibrations. Two brackets 10 are both bent and can be supported on the bottom end surface of the tunnel washer. The end surfaces abutting the bottom of the tunnel washer are roughened and provided with downwardly recessed mounting grooves 27. Within the mounting grooves 27, anti-slip pads 17, sound-absorbing pads 28, and second shock-absorbing pads 29 are arranged in order from top to bottom. The anti-slip pads 17 are made of rubber material and contact the bottom end surface of the tunnel washer. The contact end surface is provided with multiple anti-slip stripes, which can effectively increase contact friction and reduce slipping. The sound-absorbing pads 28 are made of glass fiber cotton, which is a prior art and will not be elaborated in detail in this solution. The sound-absorbing pads 28 have a noise-absorbing effect, while the second shock-absorbing pads 29 are made of energy-absorbing rubber material and can absorb a certain amount of vibration pressure, reducing the transmission of vibration to the ground, thereby achieving the purpose of noise reduction.

[0036] The bent vertical ends of the two brackets 10 are used to limit the side walls of the tunnel washer. A plurality of clamping frames 14 are arranged on the outer end faces of the vertical ends. Each clamping frame 14 is provided with a shock-absorbing component. The bent vertical ends of the brackets 10 clamp and fix the side walls of the tunnel washer through the shock-absorbing components and absorb vibrations, thereby improving the noise reduction effect.

[0037] A telescopic cylinder 18 is fixedly provided on the horizontally bent end surface of one of the brackets 10, and a telescopic rod 19 is slidably connected to the telescopic cylinder 18. The other end of the telescopic rod 19 is connected to the horizontally bent end surface of the other bracket 10. When the overall width of the tunnel washer is wider, the length of the telescopic rod 19 inside the telescopic cylinder 18 can be pulled to adjust the distance between the two brackets 10, so that the device can adapt to tunnel washers of various sizes.

[0038] A detachable sound-absorbing wrap 11 is provided at the bent vertical ends of the two brackets 10. The sound-absorbing wrap 11 is made of a flexible, sound-absorbing cotton material with good deformability. This is prior art and will not be elaborated in detail in this solution. When the two brackets 10 are used to lift and limit the tunnel washer, the sound-absorbing wrap 11 can be wrapped around the outside of the tunnel washer. The bottom ends of the sound-absorbing wrap 11 are then fixed to the bent vertical end surfaces of the brackets 10. At this time, the noise generated inside the tunnel washer is absorbed by the sound-absorbing wrap 11, thereby improving the noise reduction effect. In this solution, the specific size and length of the sound-absorbing wrap 11 are set according to actual conditions and are not subject to further restrictions in this solution.

[0039] For further information, see the attached Figure 1 and attached Figure 11A plurality of support seats 20 are fixedly connected on the bottom end surface of the bracket 10 by welding technology, and a first shock-absorbing pad 21 made of shock-absorbing rubber material is provided on the bottom end surface of the support seat 20. The first shock-absorbing pad 21 is in contact with the ground, which can effectively reduce the noise generated by vibration between the equipment and the ground. A plurality of fixing screw holes are arranged on the end surfaces of the support seat 20 and the first shock-absorbing pad 21, and the staff can fix them by cooperating with the expansion bolts and the fixing screw holes.

[0040] For further information, see the attached Figure 4 and attached Figure 9 A fixing boss 13 is fixedly provided on the end surface of the bent vertical end of the bracket 10, and a downwardly recessed fixing groove 31 is arranged on the end surface of the fixing boss 13. Connecting blocks 22 are connected to the end surfaces of both sides of the bottom of the sound-absorbing wrapping tape 11. A plurality of corresponding bolt holes are arranged on the end surfaces of the connecting block 22 and the fixing groove 31. When the sound-absorbing wrapping tape 11 needs to be installed, the staff will wrap the sound-absorbing wrapping tape 11 as a whole on the outside of the tunnel washer, insert the connecting block 22 into the fixing groove 31, and then screw the bolts into the corresponding bolt holes to fix the sound-absorbing wrapping tape 11 and the connecting block 22.

[0041] For further information, see the attached Figure 10 , Attachment Figure 11 and attached Figure 12 The inner wall surface of the bottom of the telescopic cylinder 18 is provided with an upwardly protruding limit slider 34, and a mutually cooperating limit sliding groove 33 is provided on the outer side of the limit slider 34 on the corresponding end surface of the telescopic rod 19. A plurality of fixing holes 32 corresponding to each other are provided on the end surfaces of the telescopic rod 19 and the telescopic cylinder 18. The setting of the limit slider 34 and the limit sliding groove 33 makes the telescopic rod 19 as a whole slide more smoothly inside the telescopic cylinder 18. At the same time, the raised limit slider 34 can also improve the strength of the telescopic cylinder 18 and the telescopic rod 19, thereby improving the stability. When the length of the telescopic cylinder 18 and the telescopic rod 19 is adjusted, the bolts can be screwed into the corresponding fixing holes 32 to fix the telescopic cylinder 18 and the telescopic rod 19.

[0042] For further information, see the attached Figure 4 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 8The vibration-absorbing component includes a sliding groove 30 arranged inside the clamping frame 14, and a sliding rod 23 is slidably arranged in the sliding groove 30. One end of the sliding rod 23 passes through the end surface of the bracket 10 and extends above the anti-slip pad 17. The end of the sliding rod 23 extending above the anti-slip pad 17 is connected to a clamping plate 12. The outer end surface of the clamping plate 12 is roughened. A buffer block 24 is arranged on one side of the sliding rod 23 in the clamping frame 14. The buffer block 24 is made of shock-absorbing rubber material. The buffer block 24 will abut against the area between the sliding rod 23 and the side wall of the clamping frame 14. When the tunnel washer is placed, the side wall of the tunnel washer will squeeze the clamping plate 12, thereby pushing the sliding rod 23. The push of the sliding rod 23 will cause the buffer block 24 to be squeezed. The squeezed buffer block 24 can accept the vibration transmitted from the clamping plate 12 and the sliding rod 23, and absorb the vibration, thereby absorbing the vibration of the entire tunnel washer and achieving the purpose of noise reduction.

[0043] For further information, see the attached Figure 6 When the abutment stroke of the splint 12 is insufficient, the staff can embed the pad 25 of corresponding thickness into the position between the inner wall of the sliding groove 30 and the buffer block 24, so as to fill the gap of corresponding spacing. This arrangement makes it possible to adjust the processing by pads 25 of different thicknesses when the clamping pressure of the splint 12 is insufficient, thereby improving the fixing quality. A cover plate 15 is provided at the upper end surface of the buffer block 24, and the cover plate 15 will cover the upper end surface of the clamping frame 14. A detector 16 is provided on the end surface of the cover plate 15. The detector 16 is a vibration detection detector. The detection end of the detector 16 is connected to the cover plate 15. When the buffer block 24 under the cover plate 15 vibrates, the detector 16 will detect the corresponding vibration. When the vibration frequency is too large, an alarm will be issued to remind the staff to replace the buffer block 24 or the pad 25 to ensure the clamping stability.

[0044] Example 2:

[0045] Reference Attachment Figure 6 A noise reduction device for a tunnel washer is provided, in which a hard core block 26 is filled inside a buffer block 24. The hard core block 26 is grid-shaped as a whole and is made of a hard metal material. It is filled inside the buffer block 24 to improve the overall strength of the buffer block 24. The buffer block 24 made of rubber material has good supporting strength while absorbing vibrations, will not be squeezed and deformed in a short time, and effectively increases its service life.
