This means that the swing path and range of the hose can be adjusted as needed and is no longer limited to the fixed position at the initial installation.

[0019] 2. The hose is not directly connected to the collision block on the second rotating rod, but is set separately. The hose becomes a more independent module, so that maintenance personnel can operate the hose alone without disassembling the entire drive mechanism (especially the second rotating rod and its accessories). The non-direct connection design improves the overall maintainability of the dust removal device. It makes maintenance work simpler and more direct, and also provides greater flexibility for future design and upgrades.

[0020] 3. In order to protect the hose from damage during the reciprocating swing, an elastic protection ring and internal elastic protective parts are specially designed. These components can effectively absorb and disperse the collision energy to prevent the hose from being damaged by direct collision.

[0021] 4. The rebound mechanism composed of the fixing plate, the connecting rod, the guide column, the first spring and the buffer block ensures that the hose can be smoothly reset after being pushed by the collision block and perform the next swing. This design makes the swinging action of the hose more continuous and stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-9 As shown, a dust removal device for a watch production workshop includes: a dust removal box 1, a sealing cover 2 is detachably mounted on the upper end of the dust removal box 1, and a handle is fixedly provided on the top of the sealing cover 2 (not shown in the figure). The sealing cover 2 can be opened by the handle to repair the interior of the dust removal box 1.

[0034] The interior of the dust box 1 is hollow, and a disc 4 is fixedly arranged in the middle of the bottom end of the dust box 1. The disc 4 is provided with a plurality of through-notches 41 in a ring shape, and the notches 41 are connected to the outside of the dust box 1. A gear ring 6 is rotatably arranged on the inner wall of the lower end of the dust box 1. The gear ring 6 is coaxially arranged with the disc 4, and the gear ring 6 is on the outside of the disc 4. A motor 5 is fixedly arranged at the bottom end of the dust box 1. A plurality of fixed shafts 16 are rotatably connected to the inner wall of the lower end of the dust box 1 in a ring shape. The number of the fixed shafts 16 is the same as the number of the notches 41. A gear 22 is fixedly sleeved on the outer side of the fixed shaft 16, and the gear 22 is meshed with the gear ring 6. An eccentric wheel 15 is fixedly connected to the top of the fixed shaft 16, and the output end of the motor 5 passes through the side wall of the dust box 1 and is fixedly connected to one of the fixed shafts 16.

[0035] Specifically, a limit ring is fixedly provided at the bottom of the gear ring 6, a limit groove is provided on the inner wall of the lower end of the dust removal box 1, and the limit ring is embedded in the limit groove, so that the gear ring 6 can rotate.

[0036] The top of the disc 4 is provided with a plurality of limiting mechanisms in a ring shape, and the limiting mechanisms are used to realize the linear movement of the second rotating rod 18. The limiting mechanisms include a limiting frame 20, and the limiting frame 20 is in a U-shape. The two sides of the limiting frame 20 are symmetrically fixedly connected with connecting frames 21, and the bottom end of the connecting frame 21 is fixedly connected to the top of the disc 4, and the second rotating rod 18 is slidably inserted into the inner side of the limiting frame 20.

[0037] The eccentric wheel 15 is rotatably connected to a first rotating rod 17 via a rotating pin. One end of the first rotating rod 17 away from the eccentric wheel 15 is rotatably connected to one end of a second rotating rod 18 via a rotating pin.

[0038] A water inlet pipe 3 is fixedly arranged inside the dust removal box 1, and the top of the water inlet pipe 3 passes through the sealing cover 2 and extends to the outside of the dust removal box 1. A rod body not shown in the figure is symmetrically fixedly arranged on the side of the water inlet pipe 3. The other end of the rod body is fixedly connected to the inner wall of the dust removal box 1 to fix the water inlet pipe 3. A plurality of corrugated tubes are connected to the outside of the water inlet pipe 3 in a circular array. A hose 7 is connected to the other end of the corrugated tube. The hose 7 extends downward and passes through the corresponding notch 41. The bottom of the hose 7 is a water spraying part. The hose 7 can swing back and forth inside the corresponding notch 41, and the swinging position can change.

[0039] During the dust removal process, the hose 7 needs to swing reciprocally to achieve the dust removal effect. Due to its special corrugated shape, the bellows can flexibly follow the swing of the hose 7 without breaking or being damaged, ensuring the stability and reliability of the dust removal device.

[0040] Fixing frames 9 are symmetrically arranged on both sides of the hose 7. The fixing frame 9 is in a shape of a double-square frame. The bottom end of the fixing frame 9 is fixedly connected to the top end of the disc 4. A slider 12 is slidably connected to the inner side of the fixing frame 9. Rotating members 11 are symmetrically and fixedly connected to the side surface of the hose 7. The hose 7 swings reciprocally with the rotating members 11 on both sides as the rotation axes, and the position of the rotating member 11 within the notch 41 can change, so that the position of the reciprocating swing of the hose 7 changes, thereby fully dusting the production workshop. The rotating member 11 includes a rotating shaft 1101 and two limiting blocks 1102. The rotating shaft 1101 is fixedly connected to the side surface of the hose 7. Two limiting blocks 1102 are fixedly sleeved on the outer side of the rotating shaft 1101. The rotating shaft 1101 penetrates through the corresponding slider 12, and the two limiting blocks 1102 are respectively on both sides of the slider 12. The limiting blocks 1102 can effectively prevent the rotating shaft 1101 from detaching from the slider 12.

[0041] To enable the position of the rotating member 11 to be variable, a first electric push rod 10 is fixedly arranged on the outer side of the fixing frame 9. The telescopic end of the first electric push rod 10 passes through the side wall of the fixing frame 9 and is fixedly connected to the side surface of the slider 12. When the first electric push rod 10 is started, the telescopic end of the first electric push rod 10 drives the corresponding slider 12 and the rotating member 11 as a whole to move along the length direction of the fixing frame 9 (the length direction of the fixing frame 9 is the same as the length direction of the notch 41). After the hose 7 is moved to a suitable position, then the pushing mechanism is used to reciprocally push the hose 7, so that the hose 7 swings reciprocally with the rotating members 11 on both sides as the rotation axes.

[0042] A pushing mechanism is arranged on the second rotating rod 18. The pushing mechanism includes second electric push rods 27 symmetrically arranged inside the second rotating rod 18. The telescopic ends of the second electric push rods 27 pass through the side walls of the second rotating rod 18 and are fixedly connected to a collision block 19. The collision block 19 can move synchronously with the hose 7, keeping a fixed distance between the collision block 19 and the hose 7 all the time, ensuring that the collision block 19 can always collide with the hose 7 to realize the reciprocating swing of the hose 7.

[0043] To prevent the hose 7 from being damaged during the pushing process: An elastic protection ring 8 is fixedly sleeved on the outer side of the hose 7. The elastic protection ring 8 is made of an elastic material, and a plurality of groups of elastic protection components are arranged in a circular array inside the elastic protection ring 8. The elastic protection components include a plurality of second springs 26 vertically distributed. Both ends of the second spring 26 are fixedly connected to the inner wall of the elastic protection ring 8.

[0044] When the collision block 19 contacts the hose 7, due to the presence of the elastic protection ring 8, it will first be affected by the collision force and deformed, thereby absorbing and dispersing part of the collision energy and reducing the direct impact on the hose 7. When the second spring 26 is acted upon by an external force, it can further disperse and absorb the collision energy and prevent stress concentration from causing damage to the hose 7.

[0045] In order to ensure that the hose 7 can rebound after being pushed by the pushing mechanism: a rebound mechanism is arranged above the notch 41, and the rebound mechanism includes a fixed plate 14 slidably connected to the top of the disc 4, the fixed plate 14 is above the notch 41, and the side of the fixed plate 14 and the position near the bottom are symmetrically fixedly connected with a connecting rod 13, the connecting rod 13 penetrates the corresponding fixed frame 9 and is fixedly connected to the side of the slider 12, and the side of the fixed plate 14 and the position near the top are symmetrically fixedly connected with a guide column 23, and the two guide columns 23 are slidably arranged with a buffer block 25, and the outer side of the guide column 23 is wound with a first spring 24, one end of the first spring 24 is fixedly connected to the fixed plate 14, and the other end of the first spring 24 is fixedly connected to the buffer block 25, and the buffer block 25 is provided with a fixing hole for the guide column 23 to be inserted, and the side of the buffer block 25 is provided with an arc notch, and the arc notch of the buffer block 25 is adapted to the hose 7. The rebound mechanism can move synchronously with the hose 7 to ensure that the distance between the initial position of the buffer block 25 and the hose 7 remains unchanged.

[0046] Working principle:

[0047] The dust removal box 1 is fixedly installed above the interior of the watch production workshop, and water is passed into the interior of the dust removal box 1 through the water inlet pipe 3. At the same time, the first electric push rod 10 is started, and the telescopic end of the first electric push rod 10 drives the corresponding slider 12 and the rotating member 11 to move as a whole along the length direction of the fixed frame 9 until the slider 12 and the rotating member 11 move as a whole to the inner middle position of the fixed frame 9; then the motor 5 is started, and the motor 5 drives one of the fixed shafts 16 to rotate, and the fixed shaft 16 drives the corresponding gear 22 and eccentric wheel 15 to rotate, and the gear 22 drives the ring gear 6 to rotate, and the ring gear 6 drives the remaining gears 22 to rotate, so that the remaining fixed shafts 16 and eccentric wheels 15 also rotate, and the rotation of the eccentric wheel 15 drives the corresponding first rotating rod 17 to move, and the first rotating rod 17 drives the corresponding second The rotating rod 18 realizes reciprocating linear motion. When the second rotating rod 18 drives the collision block 19 to move toward the direction of the hose 7, the collision block 19 collides with the elastic protection ring 8. The elastic protection ring 8 and the elastic protection member inside it buffer the collision force. Then the hose 7 tilts with the rotating member 11 as the rotating axis. The hose 7 will contact the buffer block 25 and continuously squeeze the first spring 24 until the first spring 24 can no longer be compressed. Then, the buffer block 25 is reset under the action of the rebound force of the first spring 24. The buffer block 25 drives the hose 7 to tilt in the opposite direction, so that the hose 7 shows a swinging effect. The second rotating rod 18 and the collision block 19 can push the hose 7 again as a whole, so that the hose 7 shows a reciprocating swinging effect. Water is sprayed from different water spraying parts of the hose 7 to perform dust removal operations.

[0048] The staff observes whether there is a dust removal blind spot inside the watch production workshop according to the on-site situation. If there is, the first electric push rod 10 is started, and the telescopic end of the first electric push rod 10 drives the corresponding slider 12 and the rotating member 11 to move forward or backward along the length direction of the fixed frame 9 for a certain distance as a whole. According to the above process, the hose 7 continues to swing back and forth to perform dust removal operations to achieve a larger dust removal area;

[0049] It should be noted that when the hose 7 moves forward, the second electric push rod 27 needs to be started so that the telescopic end of the second electric push rod 27 drives the collision block 19 to move forward the same distance; when the hose 7 moves forward and backward, the second electric push rod 27 needs to be started so that the telescopic end of the second electric push rod 27 drives the collision block 19 to move backward the same distance.

[0050] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
