Description

Technical Field

[0001] This utility model relates to the field of banknote counting machine technology, and in particular to a noise-reducing banknote counting machine. Background Technology

[0002] A banknote counting machine is a machine that integrates counting and distinguishing between genuine and counterfeit banknotes. Due to the large scale of cash circulation and the heavy workload of cash handling at bank teller counters, banknote counting machines have become an indispensable piece of equipment.

[0003] An existing patent (publication number: CN216901699U) discloses a banknote counting machine with a noise reduction structure, including a banknote counting machine body. A noise reduction component is installed on the top of the banknote counting machine body, and a hinge connects the noise reduction component to the banknote counting machine body. By adding a soundproof cover to the top of the banknote counting machine body, the noise from the friction of banknotes can be isolated. By adding a sound-absorbing cotton layer to the inner wall of the soundproof cover, the noise from the friction of banknotes can also be absorbed and reduced. In the process of implementing this solution, the following problems were found in the prior art, which have not been well resolved: The above-mentioned device reduces noise inside the banknote counting machine through the soundproof cover and the sound-absorbing cotton layer, but its sealing performance at the banknote dispensing port is poor, resulting in some noise being transmitted through the air. This utility model provides a noise-reducing banknote counting machine. Utility Model Content

[0004] To address the issue mentioned above where the soundproof cover and absorbent cotton layer reduce noise inside the banknote counter, but the poor sealing of the banknote outlet allows some noise to propagate through the air, this invention provides a noise-reducing banknote counter.

[0005] This utility model provides a noise-reducing banknote counting machine, which adopts the following technical solution:

[0006] A noise-reducing banknote counting machine includes a banknote counting machine body, with two movable slots on the front side of the banknote counting machine body, and a protective cover slidably disposed inside the movable slots;

[0007] The bottom of the protective cover has a rectangular groove, and a sealing element is slidably disposed inside the rectangular groove. A pull handle is movably inserted into the top of the protective cover.

[0008] The above technical solution facilitates dual noise reduction of the banknote detector body, reduces the possibility of noise propagation in the air, and allows for quick release of the protective cover from the banknote detector body, thereby quickly removing the banknotes that have been inspected inside the banknote detector body.

[0009] Optionally, in the above-mentioned noise-reducing banknote counter, two connecting blocks are fixedly provided at the bottom of the protective cover. The side of the connecting block slides into the interior of the moving groove. The shape of the connecting block and the shape of the interior of the moving groove are both T-shaped.

[0010] The above technical solution facilitates the T-shaped connecting block to drive the protective cover to slide stably inside the moving groove.

[0011] Optionally, in the above-mentioned noise-reducing banknote counting machine, the sealing element includes a rectangular frame, the rectangular frame is slidably disposed inside a rectangular groove, four T-shaped strips are slidably disposed on the side of the rectangular frame, a tension spring is fixedly disposed on the side of the horizontal bar of the T-shaped strip, one end of the tension spring is fixedly engaged with the side of the rectangular frame, and a compression spring is fixedly disposed on the top of the rectangular frame, the top end of the compression spring is fixedly engaged with the upper side of the inner wall of the rectangular groove.

[0012] With the above technical solution, when the rectangular frame moves the four T-shaped bars upward, the side of the vertical bar of the T-shaped bar can contact the side of the rectangular groove, thereby causing the four T-shaped bars to close inward. At the same time, it moves the rectangular frame to the upper side of the inner wall of the rectangular groove, and takes out the banknotes that have been inspected.

[0013] Optionally, in the above-mentioned noise-reducing banknote counter, a silicone strip is fixedly provided on the side of the vertical strip of the T-shaped bar, and the side of the silicone strip is in contact with the interior of the banknote counter body.

[0014] The above technical solution allows the silicone strip to seal the interior of the banknote detector body through the T-shaped strip, effectively reducing the transmission of noise in the air.

[0015] Optionally, in the above-mentioned noise-reducing banknote counting machine, the handle is C-shaped, and the sides of the two vertical strips of the C-shaped handle are fixedly engaged with the upper side of the rectangular frame.

[0016] The above technical solution makes it easy to pull the handle to move the rectangular frame upwards.

[0017] Optionally, in the above-mentioned noise-reducing banknote counter, a long frame is fixedly provided on the upper side of the inlet of the banknote counter body, and a sealing plate is slidably provided on the top of the long frame.

[0018] The above technical solution allows the sealing plate to seal the inside of the long frame, preventing dust from moving through the long frame into the interior of the banknote detector.

[0019] Optionally, in the above-mentioned noise-reducing banknote counting machine, a noise-reducing plate is fixedly installed in the middle of the bottom of the protective cover, and the noise-reducing plate is made of wave-shaped sound-absorbing sponge.

[0020] Through the above technical solution, the noise reduction board made of wave-shaped sound-absorbing sponge material has good high-frequency absorption capability, which can effectively reduce the noise generated by the banknote detector during banknote verification.

[0021] In summary, this utility model has at least one of the following beneficial effects:

[0022] By pulling the handle to move the rectangular frame downwards, the rectangular groove is released from fixing the T-shaped strips, allowing the four T-shaped strips to move through the tension springs and fit inside the bill dispensing port of the banknote detector body, sealing the bill dispensing port of the banknote detector body. At the same time, the noise reduction plate made of corrugated sound-absorbing sponge absorbs the noise inside the banknote detector body, thus achieving double noise reduction of the banknote detector body and reducing the possibility of noise propagating in the air.

[0023] By pulling the handle, the rectangular frame moves upward toward the inner wall of the rectangular slot, while the sides of the vertical bars of the four T-shaped strips come into contact with the sides of the inner wall of the rectangular slot. This causes the four T-shaped strips to be pressed inward and close, stretching the tension spring. This moves the rectangular frame to the side of the inner wall of the rectangular slot, quickly releasing the protective cover from the banknote detector body, and then quickly removing the banknotes that have been inspected inside the banknote detector body.

[0029] The following is combined with Figure 1-4 The present invention will be described in further detail below.

[0030] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 Figure 3 and Figure 4The present invention provides an embodiment of a noise-reducing banknote counter, comprising a banknote counter body 1, two movable slots 2 are provided on the front side of the banknote counter body 1, and a protective cover 3 is slidably disposed inside the movable slots 2;

[0031] The bottom of the protective cover 3 has a rectangular groove 4, and a sealing element 5 is slidably disposed inside the rectangular groove 4. A pull handle 6 is movably inserted into the top of the protective cover 3.

[0032] Working principle: When using this noise-reducing banknote counter, the protective cover 3 is moved to the ticket outlet of the banknote counter body 1 to seal it. When the banknote counter body 1 is working, the handle 6 drives the rectangular frame 501 to move to the lower side of the inner wall of the rectangular groove 4. At the same time, the rectangular groove 4 releases the T-shaped strips 502, so that the four T-shaped strips 502 move to the inside of the ticket outlet of the banknote counter body 1 and fit together through the rebound force of the tension spring 503, sealing the ticket outlet of the banknote counter body 1. At the same time, the noise reduction plate made of corrugated sound-absorbing sponge absorbs the noise inside the banknote counter body 1, thus performing double noise reduction on the banknote counter body 1 and reducing the possibility of noise propagation in the air.

[0033] By pulling the handle 6, the rectangular frame 501 is moved to the upper side of the inner wall of the rectangular groove 4. At the same time, the sides of the vertical bars of the four T-shaped bars 502 come into contact with the sides of the inner wall of the rectangular groove 4, causing the four T-shaped bars 502 to be pressed inward and close, and stretching the tension spring 503. This moves the rectangular frame 501 to the side of the inner wall of the rectangular groove 4, thereby quickly releasing the fixation between the protective cover 3 and the banknote detector body 1, and quickly taking out the banknotes that have been inspected inside the banknote detector body 1.

[0034] It should be noted that two connecting blocks 301 are fixedly installed at the bottom of the protective cover 3. The side of the connecting block 301 slides in conjunction with the inside of the moving groove 2. The shape of the connecting block 301 and the inside of the moving groove 2 are both T-shaped.

[0035] Using the above technical solution, the T-shaped connecting block 301 can drive the protective cover 3 to slide stably inside the moving groove 2.

[0036] It should be further explained that the sealing element 5 includes a rectangular frame 501, which is slidably disposed inside the rectangular groove 4. Four T-shaped strips 502 are slidably disposed on the side of the rectangular frame 501. Tension springs 503 are fixedly disposed on the side of the horizontal strip of the T-shaped strips 502. One end of the tension spring 503 is fixedly engaged with the side of the rectangular frame 501. A compression spring 504 is fixedly disposed on the top of the rectangular frame 501. The top end of the compression spring 504 is fixedly engaged with the upper side of the inner wall of the rectangular groove 4.

[0037] Using the above technical solution, when the rectangular frame 501 moves the four T-shaped strips 502 upward, the side of the vertical strip of the T-shaped strip 502 contacts the side of the rectangular groove 4, which can abut against the T-shaped strip 502, thereby causing the four T-shaped strips 502 to close inward. At the same time, it moves the rectangular frame 501 to the upper side of the inner wall of the rectangular groove 4, and takes out the banknotes that have been inspected.

[0038] It should be noted that a silicone strip 505 is fixedly provided on the side of the vertical strip of the T-shaped strip 502, and the side of the silicone strip 505 is in contact with the inside of the banknote detector body 1.

[0039] Using the above technical solution, the silicone strip 505 can seal the inside of the banknote detector body 1 through the T-shaped strip 502, effectively reducing the transmission of noise in the air.

[0040] It should be noted that the handle 6 is C-shaped, and the sides of the two vertical bars of the C-shaped handle 6 are fixedly fitted to the upper side of the rectangular frame 501.

[0041] Using the above technical solution, the handle 6 can easily move the rectangular frame 501 upwards.

[0042] It should be noted that a long frame 101 is fixedly installed on the upper side of the inlet of the banknote detector body 1, and a sealing plate 102 is slidably installed on the top of the long frame 101.

[0043] By adopting the above technical solution, the sealing plate 102 can seal the inside of the long frame 101, preventing dust from moving into the inside of the banknote detector body 1 through the long frame 101.

[0044] It should be noted that a noise reduction plate is fixedly installed in the middle of the bottom of the protective cover 3, and the noise reduction plate is made of wave-shaped sound-absorbing sponge.

[0045] Using the above technical solution, the noise reduction board made of wave-shaped sound-absorbing sponge material has good high-frequency absorption capability, which can effectively reduce the noise generated by the banknote detector during banknote verification.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
