Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a polishing device for the ribs of a folding fan. Background Art

[0002] The ribs of a folding fan are the basic part of the folding fan structure. A folding fan is mainly composed of ribs, rivets and a fan shaft, which are the key to the smooth opening and closing of the folding fan.

[0003] Ribs (folding fan ribs): The ribs are the support framework of the folding fan, usually made of materials such as bamboo or wood, and the number varies. Common ones are 16 ribs, 18 ribs, 20 ribs, 24 ribs, etc., or even more.

[0004] The shape, length, thickness and material of the ribs directly affect the appearance, feel and collection value of the folding fan.

[0005] The front end of the rib is the fan head, the end is the fan tail, and the middle part is called the fan waist. The fan head part is often exquisitely carved to add artistic beauty, while the fan waist part may have a groove design for easy installation and fixation of the fan surface.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present invention. The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0035] Such as Figure 1 And Figure 2 And Figure 3 And Figure 4As shown in the figure, the polishing device for the fan ribs of this folding fan includes a frame 1, and also includes an alternating feeding unit, a clamping unit, a polishing unit, and a material transferring unit. The number of the above-mentioned alternating feeding units is two, and the two alternating feeding units are respectively located at both ends of the frame 1. The above-mentioned polishing unit and the clamping unit are located between the two alternating feeding units. The above-mentioned alternating feeding unit has two storage parts, one storage part is located at the inner end of the alternating feeding unit, and the other storage part is located at the outer end of the alternating feeding unit. The above-mentioned material transferring unit can clamp and convey the fan ribs at the storage part at the inner end of one of the alternating feeding units to the clamping unit. The above-mentioned clamping unit can send the clamped fan ribs to the polishing unit. The above-mentioned polishing unit can polish the fan ribs entering it. The above-mentioned material transferring unit can also convey the fan ribs at the clamping unit to the storage part at the inner end of the other alternating feeding unit. The two storage parts in the above-mentioned alternating feeding unit can exchange positions.

[0036] The positions of the two storage parts in the alternating feeding unit can be interchanged.

[0037] One of the alternating feeding units is used for feeding, and the other alternating feeding unit is used for discharging.

[0038] During feeding, when the storage part at the inner end is empty, after the fully loaded storage part at the outer end exchanges positions with the above-mentioned empty storage part, the whole device can operate without stopping.

[0039] During discharging, when the storage part at the inner end is fully loaded, after the empty storage part at the outer end exchanges positions with the above-mentioned full storage part, the whole device can also operate without stopping.

[0040] The clamping unit grabs the fan ribs at the storage part and places them at the clamping unit. The clamping unit sends the clamped fan ribs to the polishing unit, and the fan ribs are quickly polished by the polishing unit. After the polishing operation is completed, the clamping unit drives the fan ribs to withdraw from the polishing unit.

[0041] At this time, the material transferring unit sends the polished fan ribs to the other alternating feeding unit.

[0042] It can be seen that the above cyclic operation can quickly polish the fan ribs.

[0043] The alternating feeding unit includes a first slide plate 2, a first guide rail 3, a second slide plate 4, a second guide rail 5, an avoidance component, and a driving component. The first guide rail 3 and the second guide rail 5 are both fixedly connected to the frame 1, and the second guide rail 5 is located below the first guide rail 3. The first slide plate 2 is connected to the first guide rail 3, the second slide plate 4 is connected to the second guide rail 5, the driving component is connected to the frame 1, and both the first slide plate 2 and the second slide plate 4 are connected to the driving component. The driving component can drive the first slide plate 2 to translate along the first guide rail 3. When the first slide plate 2 and the second slide plate 4 exchange positions, the second slide plate 4 can move along an arc trajectory under the action of the avoidance component.

[0044] Under the action of the driving component, the first slide plate 2 can translate along the first guide rail 3, and the second slide plate 4 can translate along the second guide rail 5.

[0045] Under the action of the avoidance component, the first slide plate 2 can be prevented from touching the second slide plate 4. That is to say, under the action of the avoidance component, the second slide plate 4 can pass through the lower part of the first slide plate 2 to avoid contact between the first slide plate 2 and the second slide plate 4.

[0046] Of course, the moving directions of the first slide plate 2 and the second slide plate 4 are opposite. When the first slide plate 2 enters the outer end of the alternating feeding unit, the second slide plate 4 enters the inner end of the alternating feeding unit. A storage part for loading the fan ribs is formed on the upper part of the first slide plate 2, and a storage part for loading the fan ribs is formed on the upper part of the second slide plate 4.

[0047] As Figure 2 shown, the avoidance component includes a first plate body 6, a second plate body 7, and a third plate body 8. The number of the first plate bodies 6 is two, and the two first plate bodies 6 are symmetrically arranged. The number of the second plate bodies 7 is two, and the two second plate bodies 7 are both located between the two first plate bodies 6. The third plate body 8 is located between the two second plate bodies 7. The first guide rail 3 is fixedly connected to the upper part of the first plate body 6, the second guide rail 5 is fixedly connected to the upper part of the second plate body 7. The second slide plate 4 includes a lower plate body 4a, an upper plate body 4b, a first connecting rod 4c, and a second connecting rod 4d. The lower plate body 4a is connected to the second guide rail 5, the upper plate body 4b is located directly above the lower plate body 4a. The upper end of the first connecting rod 4c is fixedly connected to the upper plate body 4b, and the middle part of the first connecting rod 4c passes through the lower plate body 4a. The upper end of the second connecting rod 4d is fixedly connected to the upper plate body 4b. The lower end of the second connecting rod 4d has a pin head 4d1 protruding towards its side. The side part of the third plate body 8 has an arc-shaped guide groove 8a, and the pin head 4d1 is embedded in the guide groove 8a.

[0048] The first plate body 6 provides enough space for the first guide rail 3 to be arranged.

[0049] The second plate body 7 provides enough space for the second guide rail 5 to be arranged.

[0050] The guiding groove 8a on the third plate body 8 is engaged with the pin head 4d1 on the second connecting rod 4d. When the lower plate body 4a translates along the second guide rail 5, the upper plate body 4b will move up and down relative to the lower plate body 4a. The upper plate body 4b after moving down can stably avoid the first sliding plate 2. Of course, a storage part for placing the fan ribs is formed on the upper part of the upper plate body 4b.

[0051] Under the action of the first connecting rod 4c, the upper plate body 4b can stably move up and down relative to the lower plate body 4a.

[0052] The lower plate body 4a has a through avoiding hole 4a1, and the middle part of the second connecting rod 4d is arranged at the avoiding hole 4a1.

[0053] The avoiding hole 4a1 can avoid the second connecting rod 4d, ensuring that the upper plate body 4b stably moves up and down relative to the lower plate body 4a.

[0054] The lower plate body 4a is fixedly connected to the cylindrical guiding cylinder 9, and the first connecting rod 4c is arranged at the guiding cylinder 9.

[0055] The contact area between the guiding cylinder 9 and the first connecting rod 4c is relatively large, and such a structure improves the moving stability of the upper plate body 4b.

[0056] The driving assembly includes a motor 10, a first transmission wheel 11, a second transmission wheel 12, a third transmission wheel 13, a fourth transmission wheel 14 and a first transmission belt 15. The first transmission wheel 11 and the second transmission wheel 12 are respectively connected to both ends of the upper part inside the first plate body 6, the third transmission wheel 13 and the fourth transmission wheel 14 are respectively connected to both ends of the lower part inside the first plate body 6, the first transmission belt 15 is sleeved on the first transmission wheel 11, the second transmission wheel 12, the third transmission wheel 13 and the fourth transmission wheel 14, and one of the transmission wheels is fixedly connected to the rotating shaft of the motor 10.

[0057] When the motor 10 drives the first transmission wheel 11 to rotate, the first transmission belt 15 sleeved on the first, second, third and fourth transmission wheels moves smoothly.

[0058] Since the first sliding plate 2 and the second sliding plate 4 are respectively connected to the upper part and the lower part of the first transmission belt 15, therefore, the first sliding plate 2 and the second sliding plate 4 can move synchronously in opposite directions, so as to achieve the purpose of exchanging the positions of the first sliding plate 2 and the second sliding plate 4.

[0059] The first sliding plate 2 has a first positioning strip 2a and a second positioning strip 2b. The first positioning strip 2a and the second positioning strip 2b are arranged in parallel. Along the length direction of the upper first positioning strip 2a, there are several recessed first positioning notches 2a1, and along the length direction of the second positioning strip 2b, there are several recessed second positioning notches 2b1. The first positioning notches 2a1 and the second positioning notches 2b1 are arranged in one-to-one correspondence.

[0060] After the fan bones are simultaneously inserted into the first positioning notch 2a1 and the second positioning notch 2b1, the fan bones can be stably positioned.

[0061] The depth dimensions of the first positioning notch 2a1 and the second positioning notch 2b1 are greater than the thickness dimension of the fan bone. Therefore, multiple overlapping fan bones can be positioned at the same set of the first positioning notch 2a1 and the second positioning notch 2b1.

[0062] A first limiting plate 16 is fixedly connected to the outside of the second positioning strip 2b, and the outside of the second positioning notch 2b1 is sealed by the first limiting plate 16.

[0063] The setting of the first limiting plate 16 can limit the fan bones to ensure that a plurality of fan bones are flush.

[0064] The second slide plate 4 is provided with a third positioning strip 4e and a fourth positioning strip 4f. The third positioning strip 4e and the fourth positioning strip 4f are arranged in parallel. A plurality of recessed third positioning notches 4e1 are provided along the length direction of the plurality of third positioning strips 4e. A plurality of recessed fourth positioning notches 4f1 are provided along the length direction of the fourth positioning strip 4f. The third positioning notches 4e1 and the fourth positioning notches 4f1 are arranged in one-to-one correspondence.

[0065] The depth dimensions of the third positioning notch 4e1 and the fourth positioning notch 4f1 are greater than the thickness dimension of the fan bone. Therefore, multiple overlapping fan bones can be positioned at the same set of the third positioning notch 4e1 and the fourth positioning notch 4f1.

[0066] A second limiting plate 17 is fixedly connected to the outside of the fourth positioning strip 4f, and the outside of the fourth positioning notch 4f1 is sealed by the second limiting plate 17.

[0067] The setting of the second limiting plate 17 can limit the fan bones to ensure that a plurality of fan bones are flush.

[0068] The material transfer unit includes a fifth driving wheel 18, a sixth driving wheel 19, a second conveyor belt 20, a third guide rail 21 and a vacuum suction cup assembly 22. The vacuum suction cup assembly 22 is connected to the third guide rail 21. The fifth driving wheel 18 and the sixth driving wheel 16 are respectively connected to the machine frame 1 at both ends of the third guide rail 21. The second conveyor belt 20 is sleeved on the fifth driving wheel 18 and the sixth driving wheel 19. The fifth driving wheel 18 or the sixth driving wheel 19 is used to be connected to a motor that can drive it to rotate continuously. The number of the vacuum suction cup assemblies 22 is two. In the initial state, the two vacuum suction cup assemblies 22 respectively correspond to the alternate feeding unit and the clamping unit at the left end. When the second conveyor belt 20 drives the two vacuum suction cup assemblies to move, the two vacuum suction cup assemblies respectively correspond to the clamping unit and the alternate feeding unit at the right end.

[0069] The fifth driving wheel 18 is used to be connected to an external driving member, such as a motor.

[0070] When the fifth driving wheel 18 rotates, the second conveyor belt 20 sleeved on the fifth driving wheel 18 and the sixth driving wheel 19 moves stably in translation.

[0071] Since both of the two vacuum suction cup assemblies 22 are connected to the second conveyor belt 20, the two vacuum suction cup assemblies 22 can move synchronously and in the same direction.

[0072] Specifically, one of the vacuum suction cup assemblies 22 grabs the fan bone and places it at the clamping unit, and the other vacuum suction cup assembly 22 grabs the fan bone and places it at another storage part. After completing the above actions, the two vacuum suction cup assemblies reset and are ready for the next grabbing operation.

[0073] The clamping unit includes a first driving member 23, a second driving member 24, a fourth guide rail 25, a substrate 26, a push plate 27, an upper clamping plate 28 and a lower clamping plate 29. The above-mentioned fourth guide rail 25 is fixedly connected to the frame 1, the above-mentioned substrate 26 is connected to the fourth guide rail 25, the above-mentioned first driving member 23 is fixedly connected to the frame 1 and the first driving member 23 can drive the substrate 26 to translate along the fourth guide rail 25. The upper clamping plate 28 and the lower clamping plate 29 are both arranged horizontally and are parallel to each other up and down. The above-mentioned second driving member 24 is connected to the upper clamping plate 28 and the lower clamping plate 29 and the second driving member 24 can drive the upper clamping plate 28 and the lower clamping plate 29 to close and open.

[0074] The first driving member 23 is used to drive the substrate 26 and the upper clamping plate 28 and the lower clamping plate 29 thereon to move towards the polishing unit. The second driving member 24 is used to close or open the upper clamping plate 28 and the lower clamping plate 29.

[0075] It further includes a cylinder 30 and a support plate 31. The cylinder body of the above-mentioned cylinder 30 is fixedly connected to the push plate 27. The support plate 31 is arranged parallel to the upper clamping plate 28 and the support plate 31 is fixedly connected to the piston rod of the cylinder 30.

[0076] When the fan bone has not entered the polishing unit, since the inner end of the fan bone is connected to the clamping unit and the outer end of the fan bone is not supported, it will sag naturally, which may cause jamming when the fan bone enters the polishing unit.

[0077] In this solution, the support plate 31 is located at the outer end of the fan bone to support the outer end of the fan bone. When the fan bone is about to enter the polishing unit, the cylinder 30 drives the support plate 31 to retract. Finally, it is ensured that the fan bone can stably enter the polishing unit.

[0078] The polishing unit is a first polishing roller 32 and a second polishing roller 33 axially fixed to the frame 1. The first polishing roller 32 and the second polishing roller 33 can be connected to an external power source.

[0079] The first polishing roller 32 and the second polishing roller 33 rotate continuously under the action of an external power source. The rotation directions of the first polishing roller 32 and the second polishing roller 33 are opposite. Such a structure can stably perform the corresponding polishing operation on the fan bone.

[0080] In the alternating feeding unit at the left end, both the first slide plate 2 and the second slide plate 4 have an appropriate amount of fan ribs. At this time, the first slide plate 2 is located at the inner end of the entire alternating unit and the first slide plate 2 is directly below the clamping unit. After the fan ribs at the first slide plate 2 are taken out, the second slide plate 4 full of fan ribs and the empty first slide plate 2 can exchange positions.

[0081] The material transfer unit clamps and places the fan ribs at the first slide plate 2 at the clamping unit. The clamping unit sends the clamped fan ribs to the polishing unit, and under the action of the polishing unit, the fan ribs are subjected to stable and rapid polishing operation.

[0082] The material transfer unit clamps and places the fan ribs at the clamping unit at another alternating feeding unit. When the first slide plate in this alternating feeding unit is full of fan ribs, the empty second slide plate exchanges positions with the full first slide plate, so that it can continue to place the polished fan ribs.

[0083] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0084] Those of ordinary skill in the art of this technology should recognize that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. As long as it is within the spirit and scope of the present invention, appropriate changes and variations made to the above embodiments fall within the scope of protection required by the present invention.
