Description

Technical Field

[0001] This invention relates to the field of flower drum production and processing technology, specifically a production and processing device for flower drums. Background Technology

[0002] Hai'an Flower Drum is a traditional folk dance from Hai'an County, Nantong City, Jiangsu Province, with a long history and profound cultural heritage. Originating in the Ming Dynasty and flourishing in the Qing Dynasty, it is an art form created and passed down by the working people of Hai'an in their long-term production and life. With its lively rhythm, graceful dance moves, and rich expressiveness, Hai'an Flower Drum is deeply loved by the people and is often used in festival celebrations, temple fairs, and other occasions, making it an important symbol of Hai'an's culture.

[0003] With the development of the times, Hai'an Flower Drum has not only been passed down as a dance form, but the flower drum used in its performance has also become a focus of research.

[0004] In existing flower drum production and processing techniques, the tension of the drumhead is a crucial step in the drum making process. Traditional methods often fail to achieve uniform tension when tightening the drumhead, resulting in an uneven surface that affects the sound and visual effects during dance performances.

[0005] Based on this, a production and processing device for flower drums is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-8 As shown, a production and processing device for flower drums includes a base 1, a positioning and rotating structure 2, a telescopic component 1 3, a placement plate 4, a tensioning structure 5, a pressure ring 61, a cutting structure 7, and a telescopic component 2 8. Two support rods 11 are symmetrically fixed on both sides of the upper end of the base 1, and a top plate 12 is fixed on the upper end of the two support rods 11. The positioning and rotating structure 2 is set on the base 1. The positioning and rotating structure 2 is used to center the drum body and drive the drum body to rotate after positioning. At each corner of the lower end of the placement plate 4, a telescopic component 3 is fixedly connected to its telescopic end. The telescopic component 3 is installed on the upper end of the base 1. A central opening 43 is provided through the middle of the upper end of the placement plate 4. Several tensioning structures 5 are installed on the upper end of the placement plate 4. The tensioning structures 5 are distributed around the central opening 43. The tensioning structures 5 are used to tighten the drum skin. The tensioning structure 5 includes a fixing block 54 and a limiting plate 521. The pressure ring 61 is located directly above the placement plate 4. The upper end of the pressure ring 61 is fixedly connected to the lower end of the pressure plate 64 by several connecting rods 63. The upper end of the pressure plate 64 is fixedly connected to the telescopic end of the telescopic component 8. One of the tensioning structures 5 has a fixing block 54 and a limiting plate 521 connected to a cutting structure 7. When the pressure plate 64 moves down, it will push the cutting structure 7 to contact the drum skin. When the positioning and rotating structure 2 drives the drum body to rotate, the cutting structure 7 cuts off the excess scraps of the drum skin.

[0029] In this embodiment, the drum body is placed on the positioning and rotating structure 2 and automatically centered. The telescopic component 3 adjusts the height of the placement plate 4 to align the drum body with the tensioning structure 5. The tensioning structure 5 evenly tightens the drumhead around the central opening 43. The telescopic component 8 drives the pressure plate 64 downwards, and the pressure ring 61 presses the drumhead, simultaneously pushing the cutting structure 7 to contact the drumhead. Then, the drumhead and drum body are fixed together by an external hammer nail device; subsequently, the positioning and rotating structure 2 drives the drum body to rotate, and during this rotation, the cutting structure 7 cuts off excess drumhead scraps.

[0030] In an optional embodiment, the positioning rotation structure 2 includes a motor 21 mounted on the upper end of the base 1. The output end of the motor 21 extends into the inner cavity of the base 1 and is fixedly connected to a gear 22. The gear 22 meshes with a gear 23 in the inner cavity of the base 1. A turntable 25 is rotatably mounted on the upper end of the gear 23. A rotation damper is provided at the connection between the gear 23 and the turntable 25. The turntable 25 is located on the upper surface of the base 1. Several oblique openings 24 are provided through the gear 23. Several straight openings 26 are provided through the turntable 25. Each oblique opening 24 matches a straight opening 26. A positioning element 27 is provided at each oblique opening 24 and its matching straight opening 26.

[0031] It should be noted that after the motor 21 starts, it drives the gear 22, which is fixedly connected to it, to rotate. The rotation of gear 22 will drive gear 23 to rotate in the opposite direction. By opening a bevel 24 on gear 23 and a straight opening 26 on the turntable 25, and each bevel 24 matches a straight opening 26, a positioning element 27 is set at the matching point. When the drum body is placed on the turntable 25, the rotation of gear 23 can engage with the bevel 24 and the straight opening 26, and the turntable 25 is suppressed by the rotation damper, thereby driving the positioning element 27 to center the drum body, ensuring that the drum body is in the center position.

[0032] After the positioning element 27 centers the drum body, since the positioning element 27 can no longer move to the center position, several positioning elements 27 clamp the drum body. The rotation damper's suppression effect on the rotation of the turntable 25 is less than the rotational force of the turntable 25. At this time, gear 23 can drive the turntable 25 and the drum body on the turntable 25 to rotate.

[0033] The rotating damper can be a unidirectional viscous rotating damper, which is a very mature and widely used existing technology, so it will not be discussed in detail here.

[0034] The positioning component 27 includes a straight rod 271, which is located at the oblique opening 24 and the straight opening 26. The lower end of the straight rod 271 passes through the oblique opening 24 and is fixed with a limit block 272. The upper end of the straight rod 271 passes through the straight opening 26 and is fixed with a straight column 273. The upper end of the straight column 273 is fixed with a contact block 274.

[0035] It should be noted that when the positioning component 27 centers the drum body, the outer wall of the drum body will contact the contact blocks 274 of each positioning component 27. Due to the location of the straight rod 271 at the bevel 24 and the straight opening 26, and the specific design of the bevel 24 and the straight opening 26, the straight rod 271 can only move in a specific direction and range, thereby adjusting the drum body to the center position and achieving center positioning.

[0036] The limiting block restricts the vertical movement range of the straight rod 271, preventing the straight rod 271 from coming out of the inclined opening 24 and the straight opening 26, and ensuring the stability of the overall structure of the positioning component 27.

[0037] The straight column 273 further enhances the connection stability between the straight rod 271 and the turntable 25, while providing a mounting base for the upper contact block 274.

[0038] In an optional embodiment, the tensioning structure 5 includes a bottom block 55 located on the inner side of the upper end of the placement plate 4. A fixing block 54 is fixed to the upper end of the bottom block 55. A vertical groove 541 is opened on the side of the fixing block 54 facing the center opening 43. A vertical rod 58 is vertically fixed in the vertical groove 541. A vertical block 571 slides in the vertical groove 541. The vertical block 571 is slidably connected to the vertical rod 58. The lower end of the vertical block 571 is fixedly connected to the upper end of the bottom block 55 through a second return spring 581. A lower wedge block 57 is fixed to the end of the vertical block 571 near the center opening 43. Several upper wedges 62 are fixed to the lower end of the pressure ring 61, and each upper wedge 62 corresponds to the position of a lower wedge 57 in a tensioning structure 5.

[0039] A plurality of sliding openings 41 are provided through the placement plate 4, each sliding opening 41 corresponding to a tensioning structure 5, and an inner sliding groove 42 is provided on the inner side wall of the sliding opening 41. A sliding rod 56 is fixed at the lower end of the bottom block 55. An outer ring 561 is sleeved on the outer side wall of the sliding rod 56. The sliding rod 56 matches the sliding opening 41, and the outer ring 561 matches the inner sliding groove 42.

[0040] The tensioning structure 5 also includes a fixing plate 51 fixed to the outer side of the upper end of the placement plate 4. A guide opening 511 is provided through the middle of the fixing plate 51. A guide rod 52 slides at the guide opening 511. A limit plate 521 is fixed to the end of the guide rod 52 away from the center opening 43. A fixing block 54 is fixed to the end of the guide rod 52 near the center opening 43. A return spring 53 is fixed between the fixing plate 51 and the fixing block 54.

[0041] It should be noted that by pressing down on the upper wedge 62, the lower wedge 57 is driven to slide down along the vertical groove 541. At the same time, the inclined plane is used to convert the vertical pressure into horizontal tension, thereby driving the fixed block 54 and the bottom block 55 to move along the sliding opening 41 away from the center opening 43, so as to achieve uniform tension on the edge of the drum skin.

[0042] When the pressure ring 61 moves downward under the drive of the telescopic member 8, the upper wedge 62 first contacts the inclined surface of the lower wedge 57. As the pressure ring 61 continues to move downward, the upper wedge 62 applies downward pressure to the lower wedge 57, causing the lower wedge 57 to slide downward along the vertical rod 58 and compress the return spring 581. At this time, the lower wedge 57 and the bottom block 55 clamp the edge of the drum skin. During this process, the inclined surface of the lower wedge 57 slides relative to the inclined surface of the upper wedge 62, generating a horizontal component force. This component force pushes the fixed block 54 and the bottom block 55 fixed thereto to move outward. The slide rod 56 and the outer ring 561 at the lower end of the bottom block 55 slide along the slide opening 41 and the inner slide groove 42, ensuring the accuracy and stability of the movement direction. At the same time, the fixed block 54 drives the guide rod 52 to slide outward in the guide opening 511 of the fixed plate 51 and compress the return spring 53. As the upper surface of the fixing block 54 moves outward, it stretches the edge of the drumhead covering it outward, thereby achieving drumhead tension.

[0043] After the drum body and drumhead are fixed by hammer nails, the pressure ring 61 continues to move downward until the upper wedge 62 separates from the lower wedge 57. At this time, the lower wedge 57 moves upward under the rebound action of the second return spring 581, releasing the drumhead. The pressure ring 61 still compresses the first return spring 53, but will not affect the drumhead. Subsequently, the positioning and rotating structure 2 will drive the drum body to rotate so that the cutting structure 7 can remove the excess scrap material of the drumhead, ensuring that the drumhead can rotate smoothly and synchronously with the drum body, thereby ensuring the neatness of the cutting edge and the final tension quality of the drumhead.

[0044] In an optional embodiment, the cutting structure 7 includes a connecting block 71, two fixing ears 72, two connecting plates 73, two fixing ears 74, a mounting plate 75, and a cutting blade 76. The connecting block 71 is fixed to the end of the limiting plate 521 away from the drum body. The two fixing ears 72 are respectively fixed to the upper ends of the connecting block 71 and the fixing block 54. Each fixing ear 72 is rotatably connected to one end of a connecting plate 73. Two fixing ears 74 are symmetrically fixed on both sides of the lower end of the mounting plate 75. Each fixing ear 74 is rotatably connected to the end of a connecting plate 73 away from the fixing ears 72. A torsion spring is installed at the rotatable connection between the connecting plate 73 and the fixing ears 72. The cutting blade 76 is fixed to the end of the mounting plate 75 near the drum body.

[0045] A baffle plate 741 is fixed at one end of the fixed ear 74 near the drum body.

[0046] A wheel cover 66 is provided directly above the mounting plate 75. A contact wheel 67 is rotatably mounted on the lower end of the wheel cover 66. The upper end of the wheel cover 66 is fixedly mounted on the lower end of the pressure plate 64 by a fixing rod 65.

[0047] It should be noted that when the pressure plate 64 moves downward under the drive of the telescopic component 8, the fixed rod 65 drives the wheel cover 66 and the contact wheel 67 to move downward synchronously. The contact wheel 67 first contacts the upper surface of the mounting plate 75, and applies downward pressure to the mounting plate 75 as the pressure plate 64 continues to press down. Since the mounting plate 75 is rotatably connected to one end of the two connecting plates 73 through the fixed ear 74, and the other end of the connecting plate 73 is rotatably connected to the upper end of the connecting block 71 and the fixed block 54 through the fixed ear 72, the mounting plate 75 will swing downward around the hinge point between the fixed ear 74 and the connecting plate 73 when subjected to downward pressure. At the same time, the connecting plate 73 also rotates relative to the fixed ear 72, forming a linkage mechanism.

[0048] During the downward pressing of the pressure plate 64, when the mounting plate 75 attempts to swing away from the drum body, the blocking plate 741 interferes with the connecting plate 73, physically preventing any swing in that direction; when the mounting plate 75 swings closer to the drum body, the blocking plate 741 does not contact any component, and the swing is unimpeded. The cutting blade 76 then approaches the edge of the drumhead, ready to cut. At this time, the mounting plate 75 is positioned above the pressure ring 61.

[0049] One end of the torsion spring is connected to the fixed lug 72, and the other end is connected to the connecting plate 73. It is used to drive the mounting plate to swing upward and reset. When the pressure plate 64 moves down and the contact wheel 67 presses down on the mounting plate 75, the torsion spring is twisted and stores energy. When the pressure plate 64 moves up and the contact wheel 67 leaves the mounting plate 75, the torsion spring releases energy and drives the mounting plate 75 to swing upward and outward to reset, so that the cutting blade 76 is removed from the drum skin area.

[0050] When the fixing block 54 returns to its initial position under the action of the return spring 53, the mounting plate 75 and the cutting blade 76 also return to their initial height and horizontal position. The cutting blade 76 is completely separated from the drumhead area, making it easy to remove the finished hub.

[0051] The above embodiment discloses a production and processing device for flower drums, wherein the drum body to be processed is placed on the turntable 25 of the positioning and rotating structure 2. A motor 21 drives gear one 22 to rotate, causing gear two 23 to rotate in the opposite direction. The bevel 24 on gear two 23 engages with the straight 26 on the turntable 25, pushing the positioning member 27 along the bevel towards the center. The contact blocks 274 of each positioning member 27 simultaneously contact the outer wall of the drum body, pushing it to the center position, thus completing automatic centering.

[0052] The drumhead is placed on the placement plate 4, with its edge positioned on the upper surface of the fixing block 54. The telescopic component 8 drives the pressure plate 64 downwards, causing the upper wedge 62 at the lower end of the pressure ring 61 to contact the lower wedge 57. The lower wedge 57 is pressed down, causing the vertical block 571 to slide down the vertical rod 58, compressing the second return spring 581. The lower wedge 57 and the bottom block 55 clamp the edge of the drumhead. The inclined surface of the lower wedge 57 slides relative to the inclined surface of the upper wedge 62, generating a horizontal force that pushes the fixing block 54 outwards. The fixing block 54 stretches the edge of the drumhead outwards, simultaneously compressing the first return spring 53, achieving uniform tension of the drumhead.

[0053] The drumhead is fixed to the drum body using an external hammer and nail device. After the drum body and drumhead are fixed together by the hammer and nail, the telescopic component 2 8 drives the pressure ring 61 to continue moving downward until the upper wedge 62 and the lower wedge 57 are completely disengaged. At this time, the lower wedge 57 moves upward under the rebound action of the return spring 2 581, releasing the lateral tension on the edge of the drumhead. The pressure ring 61 still maintains the pressure on the edge of the drumhead on the placement plate 4 and continues to compress the return spring 1 53, but will not cause additional friction or interference to the drumhead.

[0054] At this moment, the pressure plate 64 moves downward, driving the contact wheel 67 to press down the mounting plate 75 via the fixing rod 65. The mounting plate 75 swings downward and toward the drum body via the linkage mechanism connecting plate 73, fixing ear 1 72, and fixing ear 2 74. The cutting blade 76 then approaches the edge of the drumhead, ready to cut.

[0055] Motor 21 continues to drive gear 23 to rotate. At this time, positioning component 27 has clamped the drum body, and rotation damper allows turntable 25 to drive the drum body to rotate. The drum body drives the drum skin to rotate synchronously, and cutting blade 76 removes excess drum skin scraps along the edge of the drum body.

[0056] After the cutting is completed, the telescopic component 28 drives the pressure plate 64 to move upward, and the contact wheel 67 leaves the mounting plate 75.

[0057] Return spring 1 53 pushes the fixing block 54 inward to reset, and the cutting blade 76 moves upward and outward from the drumhead area via the linkage mechanism. Return spring 2 581 pushes the lower wedge block 57 upward, and the tensioning structure 5 returns to its initial state.

[0058] The height of the adjustable placement plate 4 (3) can be adjusted by the telescopic component 3, making it easier to remove the finished flower hub.

[0059] Any aspects of this invention not described in detail are well-known to those skilled in the art.

[0060] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
