Description

Technical Field

[0001] This invention relates to the field of electrostatic flocking technology for jewelry, specifically to electrostatic flocking processing methods and equipment for gold and silver jewelry. Background Technology

[0002] Electrostatic flocking technology is now widely used in the surface decoration processing of various common metal products. However, for the field of precious metal jewelry such as gold and silver, there is currently no suitable and specialized flocking processing application. Existing processes cannot be directly applied to precious metal jewelry. The reason for this is that jewelry is generally small in size, and the requirements for the fineness of the flocked surface and its skin-friendliness are much higher than those for ordinary metal workpieces. The movement mode and curing conditions of conventional flocking equipment are not compatible with the material characteristics, structural form, and processing precision requirements of precious metal jewelry, resulting in problems such as uneven flocking surface and workpiece deformation due to heat.

[0003] In existing technologies, flocking and heating / baking curing processes are independent of each other, resulting in low equipment integration. Jewelry needs to be transferred between different workstations, which is not only cumbersome and inefficient, but also prone to dust and impurities that affect the adhesion of the flock. Furthermore, multi-dimensional composite motion cannot be achieved during flocking; only single rotation is possible. For irregularly shaped, hollow, or curved precious metal jewelry, the flock is difficult to attach fully and evenly to each surface, easily leading to problems such as missed flocking and sparse or uneven flocking, resulting in poor flocking effect. In addition, existing flocking equipment does not have the function of automatically shaking to remove loose hair. After flocking, the unbonded loose hair remaining on the surface of the jewelry can only be cleaned by manual wiping or blowing air. This not only has low cleaning efficiency and poor cleanliness, but also easily damages the stable flocking surface, affecting the appearance quality of the finished product. There is currently no equipment in the industry that can simultaneously achieve multi-dimensional rotating flocking and loose hair shaking functions using the same set of moving parts, making it difficult to meet the needs of integrated and high-efficiency processing. Summary of the Invention

[0004] The purpose of this invention is to provide a method and equipment for electrostatic flocking of gold and silver jewelry in order to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The electrostatic flocking process for gold and silver jewelry provided by this invention includes the following steps: a. Wipe the surface of the jewelry with clean water to remove surface dirt and impurities; b. Apply glue to the areas of the jewelry that need flocking. c. Fix the jewelry onto the rotary swing mechanism of the electrostatic flocking equipment, start the electrostatic flocking equipment, and the flock in the flocking chamber flies up to the surface of the jewelry under the action of the high voltage electrostatic field and is vertically planted on the surface of the jewelry coated with adhesive. During the flocking process, the jewelry follows the rotary swing mechanism to rotate and swing back and forth in the flocking chamber. d. After flocking is completed, turn off the high-voltage electrostatic magnetic field of the electrostatic flocking equipment, continue to run the rotary swing mechanism and start the heating tube assembly to cure the adhesive layer. After the adhesive layer has cured, turn off the heating tube assembly. e. Increase the swing speed of the rotary swing mechanism to remove the loose hairs from the surface of the jewelry, then turn off the rotary swing mechanism and take out the product through the placement port of the flocking chamber to complete the flocking of this batch of jewelry.

[0006] Preferably, during step b, the ornament is fixed to the connector, the ornament is stabilized by holding the connector, the surface of the ornament is coated with glue, and the ornament is fixed to the rotary swing mechanism of the electrostatic flocking equipment through the connector.

[0007] As a preferred method, after the electrostatic flocking equipment is turned on, the rotary swing mechanism drives the jewelry to rotate and swing in the flocking chamber for three minutes. The adhesive layer heating time is set to a 30-minute countdown. When the surface of the heating element of the heating tube assembly reaches 60 degrees, the heating stops and is maintained. After 10 minutes, the temperature in the flocking chamber is maintained at 50 degrees, which gently heats the rotating jewelry until the heating countdown ends.

[0008] Another objective of this invention is to provide electrostatic flocking processing equipment for gold and silver jewelry, including electrostatic flocking equipment, and also including the aforementioned connecting parts for fixing the jewelry and the rotary swing mechanism, a heating tube assembly disposed in the flocking chamber of the electrostatic flocking equipment, and the rotary swing mechanism. The rotary swing mechanism includes a mounting frame rotatably connected to the flocking chamber. Several clamps for fixing the connecting parts are rotatably connected to the mounting frame. The mounting frame is also provided with a swing component for driving the clamps to swing back and forth when the mounting frame rotates. The rotary swing mechanism also includes an adjustment component and a drive component for driving the mounting bracket. The adjustment component works in conjunction with the swing component to adjust the swing speed of the clamp. Preferably, there are at least two mounting brackets, including strip frames. The two ends of the strip frames are rotatably connected to the opposite side of the inner wall of the flocking chamber via a first rotating shaft and a second rotating shaft, respectively. The second rotating shaft passes through the side wall of the flocking chamber. The strip frames are horizontally arranged inside the flocking chamber, and several strip frames are equidistant.

[0009] Preferably, the drive assembly includes a motor fixedly installed outside the electrostatic flocking equipment, and all of the rotating shafts are driven together, wherein any one end of the rotating shaft is driven together with the output shaft of the motor. If there are two rotating shafts, the transmission connection method is as follows: A sprocket is provided on the second rotating shaft, and the two sprockets are connected by a chain drive. The drive assembly also includes an outer cover fixedly installed on the surface of the electrostatic flocking equipment, used to cover the second rotating shaft and the components that drive the second rotating shaft.

[0010] Preferably, the clamp includes a rectangular sleeve rotatably connected to a strip frame via a rotating shaft. A movable plate is slidably connected inside the rectangular sleeve. A spring is provided inside the rectangular sleeve to push the movable plate closer to the inner wall of the rectangular sleeve. Limiting grooves are formed on the opposite surfaces of the movable plate and the rectangular sleeve. Guide plates are provided at the top of the two limiting grooves. The two guide plates are in an outwardly expanding shape. The movable plate is clearance-fitted with the inner wall of the rectangular sleeve. A fixed rod is provided inside the rectangular sleeve along the spring extension direction. The movable plate is slidably connected to the fixed rod.

[0011] Preferably, the swing assembly includes a torsion spring sleeved on the rotating shaft three, with both ends of the torsion spring connected to the rotating shaft three and the strip frame respectively. A gear is fixedly installed on the rotating shaft three, and a rack is slidably connected to the strip frame. The rack meshes with all the gears. A rail is provided on the strip frame, and several sliding sleeves are slidably connected to the rail. The sliding sleeves are connected to the rack. The swing assembly also includes a second support block disposed in the flocking chamber. A sliding cavity is provided through the flocking chamber, and a first support block is disposed in the sliding cavity. The first support block, the second support block, and the side of the rack corresponding to each other together form an inclined annular bearing surface. A roller is provided at the end of the rack. The roller contacts the annular bearing surface. When the roller contacts the lowest point of the annular bearing surface, the torsion spring is in its initial state.

[0012] Preferably, the adjustment assembly includes a connecting rod disposed outside the electrostatic flocking equipment, the connecting rod being connected to all of the support blocks, an electric push rod disposed outside the electrostatic flocking equipment for driving the connecting rod to move horizontally, the movable end of the electric push rod being connected to the connecting rod, and a guide rod disposed on the electrostatic flocking equipment for guiding the connecting rod.

[0013] Preferably, the electrostatic flocking equipment is divided into an equipment room and a flocking room. The equipment room is used to house the control part of the high voltage generating unit and the heating tube assembly. The inner wall of the equipment room is covered with heat insulation material. The surface of the flocking room is provided with a placement opening, and the placement opening is provided with a sealing cover.

[0014] The beneficial effects are: 1. This invention integrates flocking and heating / baking curing processes into the same equipment, achieving integrated flocking and curing processing. It eliminates the need to transfer jewelry between different workstations, simplifying the processing flow and significantly improving processing efficiency. At the same time, it avoids dust and impurities from being picked up during jewelry transfer, effectively ensuring the firmness of the flocking adhesion and reducing the risk of bumps and scratches on precious metal jewelry.

[0015] 2. This invention can drive jewelry to achieve multi-dimensional composite movement, replacing the traditional single rotation movement. For irregular, hollow, and curved precious metal jewelry, it can make the flocking fully and evenly adhere to each surface of the jewelry, fundamentally solving the problems of missing flocking and uneven flocking, and significantly improving the uniformity of flocking and processing effect.

[0016] 3. This invention has an automatic shaking function to remove loose hair. After flocking is completed, it can automatically clean the loose hair remaining on the surface of the jewelry without the need for manual wiping or blowing. This not only improves the efficiency and cleanliness of loose hair removal, but also avoids damage to the already stably bonded flocking surface by manual operation, thus ensuring the appearance quality of the finished product.

[0017] 4. This invention can simultaneously achieve multi-dimensional rotating flocking and loose hair shaking functions through the same set of moving parts. The equipment has a higher degree of integration and a more streamlined structure. There is no need to add an additional independent hair removal mechanism, which truly meets the needs of integrated and high-efficiency processing and is more suitable for large-scale flocking processing of precious metal jewelry.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] like Figure 9 As shown, this invention provides a method for electrostatic flocking of gold and silver jewelry, comprising the following steps: a. Wipe the surface of the jewelry with clean water to remove surface dirt and impurities; b. Apply glue to the areas of the jewelry that need flocking. c. Fix the ornament to the rotary swing mechanism 2 of the electrostatic flocking equipment 1, start the electrostatic flocking equipment 1, and the fluff in the flocking chamber 102 flies to the surface of the ornament under the action of the high voltage electrostatic field and is vertically planted on the surface of the ornament coated with adhesive. During the flocking process, the ornament follows the rotary swing mechanism 2 to rotate and swing back and forth in the flocking chamber 102. d. After flocking is completed, turn off the high-voltage electrostatic magnetic field of electrostatic flocking equipment 1, the rotary swing mechanism 2 continues to run and the heating tube assembly 3 is started to cure the adhesive layer. After the adhesive layer is cured, turn off the heating tube assembly 3. e. Increase the swing speed of the rotary swing mechanism 2 to remove the loose hairs from the surface of the jewelry, then close the rotary swing mechanism 2 and take out the product through the placement port of the flocking chamber 102 to complete the flocking of this batch of jewelry.

[0023] As an optional implementation, when step b is performed, the ornament is fixed to the connector 4, the ornament is stabilized by holding the connector 4, the surface of the ornament is coated with glue, and the ornament is fixed to the rotary swing mechanism of the electrostatic flocking equipment through the connector 4. Specifically, connector 4 can be made of wood. One end of the wood strip is inserted into the ornament, and the other end is inserted into the clamp 204 of the rotary swing mechanism 2. This connection structure is a common existing technology in the field of flocking processing and is also a conventional means in the industry to connect ornaments and auxiliary tooling. The technology is mature and reliable and can be implemented stably without creative improvements.

[0024] Specifically, regarding the function of this connection method, operators can directly hold the connector 4 to complete the glue application on the surface of the jewelry without directly contacting the jewelry body. This ensures a stable and controllable glue application process, improves the uniformity of glue application, and avoids hand stains and fingerprints from contaminating the surface of the jewelry, thus ensuring the quality of subsequent flocking and bonding. At the same time, this universal connection method is easy to assemble and disassemble, and can quickly complete the assembly of the jewelry and the connector 4, adapting to the operational needs of batch processing.

[0025] Furthermore, the end of the connector 4 furthest from the ornament is fitted and inserted into the clamp 204. After the glue is applied, the connector 4 can be directly clamped onto the rotary swing mechanism 2, achieving a seamless connection between the glue application process and the flocking process, further improving the overall processing efficiency.

[0026] As an optional implementation, after the electrostatic flocking equipment is turned on, the rotary swing mechanism drives the jewelry to rotate and swing in the flocking chamber for three minutes. The adhesive layer heating time is set to a 30-minute countdown. When the surface of the heating element of the heating tube assembly reaches 60 degrees, the heating stops and is maintained. After 10 minutes, the temperature in the flocking chamber is maintained at 50 degrees, and the rotating jewelry is slightly heated until the heating countdown ends.

[0027] This embodiment also discloses electrostatic flocking equipment for gold and silver jewelry, see [link to relevant documentation]. Figures 1-10 The device includes an electrostatic flocking equipment, characterized in that it further includes the connecting member 4 for fixing the installation decoration and the rotary swing mechanism as described in claims 1-3, the heating tube assembly 3 and the rotary swing mechanism 2 disposed in the flocking chamber 102 of the electrostatic flocking equipment 1; The rotary swing mechanism 2 includes a mounting frame 201 rotatably connected in the flocking chamber 102. Several clamps 204 for fixing the connecting piece 4 are rotatably connected on the mounting frame 201. The mounting frame 201 is also provided with a swing component 205, which drives the clamps 204 to swing back and forth when the mounting frame 201 rotates. The rotary swing mechanism 2 also includes an adjustment component 203 and a drive component 202 for driving the mounting bracket 201. The adjustment component 203 cooperates with the swing component 205 to adjust the swing speed of the clamp 204.

[0028] Specifically, the space of the electrostatic flocking equipment 1 is divided into an equipment room 101 and a flocking room 102. The equipment room 101 is used to house the control part of the high voltage generating unit and the heating tube assembly 3. The inner wall of the equipment room 101 is covered with heat insulation material 104. The surface of the flocking room 102 is provided with a placement opening 103, and a sealing cover is provided at the placement opening 103. Specifically, the principle of electrostatic flocking equipment 1 is as follows: Firstly, the electrostatic flocking equipment 1 is an existing technology. It uses a high-voltage electrostatic field to polarize the short flocks in the flocking chamber and make them carry a negative charge. Under the action of the electric field force, they fly vertically towards the grounded ornament surface, achieving directional, upright, and uniform arrangement. In this embodiment, the electrostatic flocking equipment 1 differs from the prior art only in that a heating tube assembly 3 is provided in the flocking chamber 102, and heat transfer from the flocking chamber 102 to the equipment chamber 101 is achieved by adding heat insulation material 104 in the equipment chamber 101. At the same time, the equipment chamber 101 is also equipped with active heat dissipation, the specific form of which is not limited and can directly adopt industry-standard methods. It should be noted that the temperature of the heating tube assembly 3 is set at around 60 degrees Celsius, which is sufficient to dry the adhesive layer, but this temperature will not cause any damage to the flocking chamber 102 or the internal flocking.

[0029] In some specific embodiments, see Figure 8 There are at least two mounting brackets 201, including a strip frame 2012. The two ends of the strip frame 2012 are rotatably connected to the opposite side of the inner wall of the flocking chamber 102 through a first rotating shaft 2011 and a second rotating shaft 2013, respectively. The second rotating shaft 2013 passes through the side wall of the flocking chamber 102. The strip frame 2012 is horizontally set inside the flocking chamber 102, and several strip frames 2012 are equidistant.

[0030] The strip frame 2012 is supported in the flocking chamber 102 by the first rotating shaft 2011 and the second rotating shaft 2013 at both ends and can rotate freely, serving as a rotating load-bearing structure for the ornaments; multiple strip frames 2012 are arranged horizontally and equidistantly to ensure a uniform processing environment for each ornament and to avoid collisions between them during operation.

[0031] See Figure 1 The drive assembly 202 includes a motor 2021 fixedly installed outside the electrostatic flocking equipment 1, and all the rotating shafts 2013 are connected in a transmission, wherein the end of any one of the rotating shafts 2013 is connected in a transmission to the output shaft of the motor 2021. If there are two 2013 rotating shafts, the transmission connection method is as follows: A sprocket 2023 is provided on the second rotating shaft 2013, and the two sprockets 2023 are connected by a chain 2022. The drive assembly 202 also includes an outer cover 2024 fixedly mounted on the surface of the electrostatic flocking device 1, for covering the second rotating shaft 2013 and the components that drive the second rotating shaft 2013.

[0032] The motor 2021 drives one of the rotating shafts 2013 to rotate, and then through the meshing transmission of the sprocket 2023 and the chain 2022, all the rotating shafts 2013 rotate synchronously, realizing the linkage of multiple sets of mounting frames 201, and meeting the needs of batch jewelry processing.

[0033] In some other embodiments, such as when there are more than two mounting brackets 201, the transmission structure is no longer suitable for using sprockets and chains, and a bevel gear set transmission can be used to ensure the stable rotation of each mounting bracket 201.

[0034] Furthermore, the outer cover 2024 completely protects the exposed transmission components, preventing transmission jamming and component wear, while also preventing personnel from touching the operating parts, thus improving the safety of equipment operation.

[0035] In some specific embodiments, see Figure 6 The clamp 204 includes a rectangular sleeve 2041 rotatably connected to the strip frame 2012 via a pivot 2051. A movable plate 2042 is slidably connected inside the rectangular sleeve 2041. A spring 2043 is provided inside the rectangular sleeve 2041 to push the movable plate 2042 closer to the inner wall of the rectangular sleeve 2041. Limiting grooves 2044 are provided on the opposite surfaces of the movable plate 2042 and the rectangular sleeve 2041. Guide plates 2045 are provided at the top of the two limiting grooves 2044. The two guide plates 2045 are in an outwardly expanding shape. The movable plate 2042 is clearance-fitted with the inner wall of the rectangular sleeve 2041. A fixing rod 2046 is provided inside the rectangular sleeve 2041 along the extension and retraction direction of the spring 2043. The movable plate 2042 is slidably connected to the fixing rod 2046.

[0036] Specifically, the rectangular sleeve 2041 is rotatably connected to the strip frame 2012 via the pivot 2051, allowing the entire fixture to swing back and forth with the pivot 2051, providing a basis for the composite motion flocking of the jewelry.

[0037] Specifically, regarding the movable plate 2042 and the spring 2043, the spring 2043 continuously pushes the movable plate 2042, causing it to move closer to the inner wall of the rectangular sleeve 2041. The clamping force is formed through the limiting grooves 2044 on both sides, which stably clamps the connecting piece and prevents the ornament from loosening or shifting during rotation and swing.

[0038] Furthermore, the fixed rod 2046 provides linear guidance to the movable plate 2042, ensuring that the movable plate slides only along the direction of spring extension and retraction, thus guaranteeing a smooth and non-skewed clamping action.

[0039] Specifically, the outward-expanding guide plate 2045 can guide and center the connector when it is installed, allowing the connector to fall smoothly into the limiting groove 2044 and achieve quick clamping.

[0040] It should be noted that the principle of the clamp 204 is matched with that of the connector 4. The connector 4 can be directly inserted between the two limiting grooves 2044. The thrust of the spring 2043 can directly compress the connector 4. The static friction between the limiting groove 2044 and the connector 4 is sufficient to fix the connector 4.

[0041] In some specific embodiments, see Figure 5 , Figure 8 The swing assembly 205 includes a torsion spring 2052 sleeved on the rotating shaft 2051. The two ends of the torsion spring 2052 are respectively connected to the rotating shaft 2051 and the strip frame 2012. A gear 2053 is fixedly installed on the rotating shaft 2051. A rack 2054 is slidably connected on the strip frame 2012. The rack 2054 meshes with all the gears 2053. A rail rod 2058 is provided on the strip frame 2012. Several sliding sleeves 2059 are slidably connected on the rail rod 2058. The sliding sleeves 2059 are connected to the rack 2054. The swing assembly 205 also includes a second support block 2057 disposed in the flocking chamber 102. A sliding cavity 2060 is disposed through the flocking chamber 102, and a first support block 2056 is disposed in the sliding cavity 2060. The first support block 2056, the second support block 2057 and the corresponding side of the rack 2054 together form an inclined annular bearing surface. A roller 2055 is disposed at the end of the rack 2054. The roller 2055 contacts the annular bearing surface. When the roller 2055 contacts the lowest point of the annular bearing surface, the torsion spring 2052 is in its initial state.

[0042] Specifically, regarding the core transmission structure of the swing assembly 205, the rail rod 2058 is fixed to the strip frame 2012, and the sliding sleeve 2059 is fixed to the rack 2054 and slidably sleeved on the rail rod 2058, providing linear guidance for the rack 2054 and ensuring that it moves smoothly back and forth only along the direction of the rail rod; the rack 2054 meshes with all the gears 2053, and can synchronously drive multiple rotating shafts 2051 and clamps 204 to rotate.

[0043] Specifically, regarding the cooperation between the inclined annular bearing surface and the roller 2055, the support block 1 2056 and the support block 2057 together form the inclined annular bearing surface, and the roller 2055 at the end of the rack 2054 is always in contact with this bearing surface. When the strip frame 2012 rotates with the mounting frame 201, the roller 2055 rolls along the inclined annular bearing surface. Due to the inclination difference of the bearing surface, the rack 2054 is pushed to slide back and forth along the rail 2058, and then the gear 2053 drives the rotating shaft 3 2051 to rotate, thereby realizing the reciprocating swing of the clamp 204.

[0044] Furthermore, the torsion spring 2052 is sleeved on the rotating shaft 2051 and its two ends are fixed to the rotating shaft 2051 and the strip frame 2012 respectively. When the roller 2055 rolls along the bearing surface and the clamp 204 swings, the torsion spring 2052 undergoes elastic deformation and generates a reset torque, ensuring that the roller 2055 is always in close contact with the inclined annular bearing surface, avoiding the interruption of swing due to loss of contact, and ensuring the continuous and stable swing action of the clamp 204. The support block 2056 is fitted with the side wall of the flocking chamber 102 with a clearance, and can move flexibly horizontally, reserving space for subsequent adjustment of the swing amplitude.

[0045] In some specific embodiments, see Figure 5 , Figure 7 The adjustment component 203 includes a connecting rod 2031 disposed outside the electrostatic flocking equipment 1. The connecting rod 2031 is connected to all the support blocks 2056. An electric push rod 2033 is disposed outside the electrostatic flocking equipment 1 to drive the connecting rod 2031 to move horizontally. The movable end of the electric push rod 2033 is connected to the connecting rod 2031. A guide rod 2032 is also disposed on the electrostatic flocking equipment 1 to guide the connecting rod 2031.

[0046] Specifically, the electric push rod 2033 can push the connecting rod 2031 to move horizontally along the guide rod 2032. Through the connecting rod 2031, all support blocks 1 2056 are moved synchronously, changing the relative mating position of support block 1 2056 and support block 2 2057, so that the inclined annular bearing surface formed by the two together has a cross-sectional notch. When the roller 2055 rotates with the strip frame 2012 to the cross-sectional position, the rack 2054 will instantly lose lateral support. At this time, the pre-stored torsion spring 2052 can quickly release the elastic force, driving the rotating shaft 3 2051 and the clamp 204 to rotate and rebound instantly, realizing the high-speed swing of the clamp, thereby obtaining a stronger swinging effect in the process of removing loose hair. Furthermore, the adjustment component 203 can achieve two different clamping motion effects by adjusting the horizontal displacement of the support block 2056, adapting to actual machining needs: When the electric push rod 2033 moves the support block 2056 to a position completely separated from the roller 2055, the roller 2055 completely loses the support of the annular bearing surface, and the torsion spring 2052 instantly releases the stored energy, driving the clamp 204 to rotate and rebound at high speed, forming a strong swinging effect, which can efficiently remove the loose hair on the surface of the jewelry. When support block 1 2056 moves and forms a significant relative height difference with support block 2057, but roller 2055 can still maintain contact with the bearing surface formed by the two, roller 2055 will generate an impact when it rolls to the height difference, causing clamp 204 to vibrate, which can help remove residual loose hair on the surface of the jewelry and strengthen the adhesion between the fluff and the adhesive layer.

[0047] In summary, by adjusting the position of support block 2056 using electric push rod 2033, the two effects of swinging and impact vibration can be flexibly switched. According to the actual processing needs after flocking of the jewelry, the appropriate motion mode can be selected to ensure that the loose hair is thoroughly removed and the flocking is firmly adhered.

[0048] Working principle of the invention: During operation, the connector 4 is first connected and fixed to the jewelry in the conventional way in this industry. The operator holds the connector 4 to complete the glue application on the surface of the jewelry to be flocked. After the glue is applied, the connector 4 is installed into the clamp 204. The spring 2043 pushes the movable plate 2042, which, together with the limiting groove 2044, clamps and positions the connector.

[0049] After the equipment is started, the motor 2021 in the drive assembly 202 runs, driving the second rotating shaft 2013 to rotate, and through the sprocket 2023 and chain 2022, all the strip frames 2012 rotate synchronously around the first rotating shaft 2011 and the second rotating shaft 2013; the outer cover 2024 protects the transmission components to prevent lint from entering and causing jamming.

[0050] During the rotation of the strip frame 2012, the roller 2055 at the end of the rack 2054 rolls along the inclined annular bearing surface formed by the first support block 2056 and the second support block 2057, forcing the rack 2054 to move linearly back and forth along the rail 2058 and the sliding sleeve 2059. The meshing of the rack 2054 and the gear 2053 drives the rotating shaft 2051 to rotate. The torsion spring 2052 continuously provides the reset torque, so that the roller 2055 always fits against the annular bearing surface, thereby driving the clamp 204 and the ornament to swing back and forth synchronously while rotating.

[0051] At this time, the high-voltage electrostatic field of the electrostatic flocking equipment 1 is working. Under the action of the electric field, the flocking fibers fly vertically to the surface of the glued ornament to complete the flocking. The combined rotation and swinging motion of the ornament can ensure that the flocking is seamless and uniform.

[0052] After flocking is completed, the heating tube assembly 3 heats the inside of the flocking chamber 102 to achieve low-temperature curing of the adhesive layer. The heat insulation material 104 in the equipment chamber 101 blocks heat transfer and protects the internal electrical components.

[0053] During the lint removal stage, the electric push rod 2033 of the adjusting component 203 drives the connecting rod 2031 to move along the guide rod 2032, adjusting the position of the support block 1 2056. When the support block 1 2056 and the support block 2 2057 form a height difference but the roller 2055 is still in contact, the roller rolls and generates impact vibration, shaking off the lint. When the support block 1 2056 moves to the point where the bearing surface is discontinuous, the torsion spring 2052 instantly rebounds, causing the clamp 204 to swing at high speed, forcefully removing the surface lint, and finally completing the entire flocking, curing, and lint removal process.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention 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 the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
