Abstract
Description
Technical Field
[0001] This utility model relates to a positioning mechanism for the pressure strip of a pearl nailing machine. Background Technology
[0002] Pearl-attaching machines are used to attach pearl ornaments to bags and other items. Their working principles primarily involve ultrasonic principles (electronic circuits and transducers convert electrical energy into mechanical energy vibration, melting the hot melt adhesive and adhering the pearl to the bag fabric) and cylinder-pressing principles (using cylinder force to fix the beads with four-claw nails, with computer program control for automatic bead unloading, nailing, and infrared positioning). They feature precise positioning (laser and infrared positioning ensure neatness and firmness), high efficiency and labor saving (riveting speed 8-10 times faster than manual labor), simple operation (foot pedal control, easy-to-understand interface, automatic device), wide applicability (can attach 4-12mm round and irregularly shaped beads, suitable for leather, fabric, and other materials), and diverse functions (counting, fault detection, adjustable riveting). However, existing pearl-attaching machines, when processing different products, require adjustments based on the different types and styles of pearls, making maintenance and adjustment difficult. This leads to difficulties in unshaped pearl materials being processed, reducing production efficiency and hindering business profitability. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a positioning mechanism for the pressure strip of a pearl nailing machine. It has a simple structure, is easy to maintain and adjust, and effectively improves production and processing efficiency.
[0004] To achieve the above objectives, this utility model provides a positioning mechanism for a pearl-pinning machine's pressure strip, comprising a machine body, a shaped vibratory feeder on the machine body, a flow channel at the outlet of the shaped vibratory feeder, a feeding channel on the flow channel, a punch mechanism at the end of the flow channel on the machine body, a pressure strip fitted on the flow channel, the pressure strip being separately configured to form a pressure strip front bar and a pressure strip head, the pressure strip front bar being arranged along the flow channel, one end of the pressure strip head being fixedly connected to the pressure strip front bar, and the other end being provided with a guide groove, the output end of the punch mechanism being disposed through the guide groove, and a connector seat being movably disposed on the machine body, a flow channel receiving plate being oscillatingly disposed in the connector seat, the flow channel receiving plate being disposed below the guide groove.
[0005] The advantages of this design are as follows: Existing flow channel structures lack flexible adjustment capabilities, and irregularly shaped parts are prone to mutual compression at narrow or turning points, leading to frequent production line shutdowns for cleaning and severely impacting production progress. This pearl studding machine's pressure bar positioning mechanism, with its split pressure bar design, allows for quick disassembly of the pressure bar head and front bar, enabling cleaning and unblocking of the flow channel. For larger irregularly shaped parts, operators can adjust the pressure bar spacing according to material characteristics, widening the flow channel space and allowing the parts to pass smoothly, greatly reducing the probability of jamming and ensuring continuous and stable production. In the processing of different styles of pearl jewelry, subsequent processes such as punch setting have strict requirements on the material exit angle. Operators only need to fine-tune the connector seat and change the angle of the flow channel connecting plate to precisely control the exit posture of irregularly shaped parts. When processing curved pearl decorations, adjusting the angle of the flow channel connecting plate allows the irregularly shaped part to slide out at a specific tilt angle, ensuring that the punch accurately embeds into the decorative carrier along a preset trajectory, significantly improving product processing accuracy and yield, and meeting diverse production needs.
[0006] As a further feature of this utility model, the connector seat is provided with an adjustment elongated hole along the height direction of the machine body, and the machine body is provided with a fixing hole corresponding to the position of the adjustment elongated hole. A fastening screw is fitted in the adjustment elongated hole, and the fastening screw and the fixing hole are threadedly engaged to fix the connector seat on the machine body.
[0007] The advantages of this design are as follows: In actual production, when faced with materials of different thicknesses and shapes, operators only need to loosen the fastening screws and move the connector up and down along the adjustment hole to quickly adjust the height of the flow channel plate. No complicated tools are required, and the adjustment can be completed in seconds, greatly shortening equipment setup time. The threaded connection between the fastening screws and the fixing holes ensures that the connector is stable and does not wobble during equipment operation, maintaining precise positioning even during long-term, high-frequency operation. This design allows the equipment to easily adapt to various material specifications, from thin pearl flakes to thick, irregularly shaped decorative objects, ensuring accurate feeding and significantly improving equipment versatility and production efficiency.
[0008] As a further feature of this utility model, a positioning step is provided at one end of the front bumper near the head of the bumper, and a positioning boss extends from the head of the bumper toward the positioning step. The positioning boss abuts against the positioning step, and the positioning step and the positioning boss are fastened together by locking screws.
[0009] The advantages of this design are as follows: During assembly, the positioning boss and positioning step precisely engage, forming a stable limiting structure that ensures rapid alignment of the pressure strip head and the pressure strip front bar, significantly improving installation efficiency. After the locking screws are tightened, the two fit tightly together, minimizing sway even during high-speed operation or external vibrations due to the mutually abutting step and boss structure. This ensures the flow channel maintains a stable shape, guaranteeing precise conveying paths for irregularly shaped parts, preventing material shifting or jamming due to loose components, effectively extending equipment lifespan, and reducing maintenance costs.
[0010] As a further feature of this utility model, a connecting seat is provided on the front bumper and the head of the pressure strip, and a positioning block is provided on the connecting seat. The positioning block includes a horizontal part and a vertical part. A first connecting elongated hole is provided on the connecting seat. The horizontal part and the vertical part are combined to form an L-shape. A first connecting pin is threadedly engaged on the horizontal part. The first connecting pin passes through the first connecting elongated hole. A second connecting elongated groove is provided on the vertical part. A second connecting pin is provided on the flow channel sidewall at the thread position corresponding to the second connecting elongated groove. The second connecting pin passes through the second connecting elongated groove and engages with the thread of the flow channel sidewall.
[0011] The advantages of this design are as follows: The horizontal part of the L-shaped positioning block engages with the first connecting hole of the connecting seat via a first connecting pin, while the vertical part connects to the side wall of the flow channel via a second connecting pin passing through a second connecting groove. This double connection forms a stable triangular support structure, effectively dispersing vibration and pressure during equipment operation and preventing the pressure bar from loosening or shifting. When the pressure bar position needs to be adjusted to accommodate different material specifications, the operator only needs to loosen the first and second connecting pins, utilizing the space provided by the long hole and groove to make millimeter-level fine adjustments in both horizontal and vertical directions. After adjustment, the screws are retightened, ensuring precise positioning of the pressure bar and guaranteeing the stability and efficiency of conveying irregularly shaped parts.
[0012] As a further feature of this utility model, a flow channel connector is provided at the end of the flow channel, and fasteners are respectively provided on both sides of the feed channel on the flow channel connector. A positioning pin is provided on the flow channel connector, and a sliding groove is provided on the fastener to engage with the positioning pin.
[0013] The advantages of this design are as follows: In actual production, the flow channel connector achieves a precise and flexible connection through the cooperation of fasteners and positioning pins. The engagement of the positioning pins with the sliding groove ensures a stable connection between the flow channel connector and the feeding channel, preventing misalignment and leakage during material transport, and also facilitates fine-tuning. Operators can adjust the position and angle of the flow channel connector by sliding the fasteners along the sliding groove according to the material characteristics and subsequent processing requirements, precisely controlling the discharge direction and speed. After fine-tuning, the fasteners and positioning pins are re-engaged, forming a reliable connection, ensuring that each irregularly shaped part can be discharged smoothly in an ideal posture, significantly improving processing accuracy and production efficiency.

[0017] This utility model provides an embodiment of a positioning mechanism for the pressure strip of a pearl-pinning machine, such as... Figures 1 to 3As shown, the system includes a machine body 1, on which a vibratory feeder for irregularly shaped parts is mounted. The vibratory feeder has a flow channel 2 at its outlet, and a feeding channel is provided on the flow channel 2. A punch mechanism 3 is mounted on the machine body 1 at the end of the flow channel 2. A pressure strip is fitted onto the flow channel 2. The pressure strip is divided into a front bar 41 and a head 42. The front bar 41 is positioned along the flow channel 2. One end of the head 42 is fixedly connected to the front bar 41, and the other end has a guide groove 421. The output end of the punch mechanism 3 passes through the guide groove 421. A connector seat 7 is also movably mounted on the machine body 1. A flow channel receiving plate 71 is oscillating within the connector seat 7 and is positioned below the guide groove 421. The advantage of this design is that the existing flow channel 2 structure lacks flexible adjustment capabilities, and irregularly shaped parts are prone to mutual compression at narrow or turning points in the flow channel 2, leading to frequent production line shutdowns for cleaning and severely impacting production progress. The pearl studding machine's pressure bar positioning mechanism, with its split pressure bar design, allows for quick disassembly of the pressure bar head 42 and front bar, enabling cleaning and unblocking of the flow channel 2. For larger irregularly shaped parts, operators can adjust the pressure bar spacing according to material characteristics, widening the flow channel 2 to allow the parts to pass smoothly, significantly reducing the probability of jamming and ensuring continuous and stable production. In the processing of different styles of pearl jewelry, subsequent processes such as punch setting have strict requirements on the material's exit angle. Operators only need to fine-tune the connector seat 7 and change the angle of the flow channel receiving plate 71 to precisely control the exit posture of irregularly shaped parts. When processing curved pearl decorations, adjusting the angle of the flow channel receiving plate 71 allows the irregularly shaped part to slide out at a specific tilt angle, ensuring that the punch accurately embeds into the decorative carrier along a preset trajectory, significantly improving product processing accuracy and yield, and meeting diverse production needs.
[0018] As a further feature of this embodiment, the connector seat 7 is provided with an adjustment elongated hole 72 along the height direction of the machine body 1. The machine body 1 is provided with a fixing hole corresponding to the position of the adjustment elongated hole. A fastening screw fits into the adjustment elongated hole, and the fastening screw and the fixing hole are threadedly engaged to fix the connector seat 7 on the machine body 1. The beneficial effect of this design is that, in actual production, when faced with materials of different thicknesses and shapes, the operator only needs to loosen the fastening screw and move the connector seat 7 up and down along the adjustment elongated hole 72 to quickly adjust the height of the flow channel plate 71. No complicated tools are required, and the adjustment can be completed within seconds, greatly shortening the equipment debugging time. The threaded connection between the fastening screw and the fixing hole ensures that the connector seat 7 is stable and does not wobble during equipment operation, maintaining accurate positioning even during long-term high-frequency operation. This design allows the equipment to easily adapt to various specifications of materials, from thin pearl flakes to thick, irregularly shaped decorative objects, ensuring accurate feeding and significantly improving the equipment's versatility and production efficiency.
[0019] As a further feature of this embodiment, a positioning step is provided at one end of the pressure strip front bar 41 near the pressure strip head 42. A positioning boss extends from the pressure strip head 42 towards the positioning step, and the positioning boss abuts against the positioning step. The positioning step and the positioning boss are secured together with locking screws. The advantages of this design are: during assembly, the positioning boss and positioning step precisely engage, forming a stable limiting structure, ensuring rapid alignment of the pressure strip head 42 and the pressure strip front bar 41, significantly improving installation efficiency. After the locking screws are tightened, the two fit tightly together, and even when the equipment is running at high speed or subjected to external vibrations, the swaying amplitude can be controlled to a minimal range thanks to the mutually abutting step and boss structure. This ensures that the flow channel 2 maintains a stable shape, guarantees accurate conveying path for irregularly shaped parts, avoids material deviation and jamming due to loose components, effectively extends equipment lifespan, and reduces maintenance costs.
[0020] As a further feature of this embodiment, connecting seats 5 are respectively provided on the front bar 41 and the head bar 42 of the pressure bar. A positioning block 6 is provided on the connecting seat 5, and the positioning block 6 includes a horizontal part and a vertical part. A first connecting elongated hole 51 is provided on the connecting seat 5. The horizontal and vertical parts are combined to form an L-shape. A first connecting pin is threaded onto the horizontal part, passing through the first connecting elongated hole 51. A second connecting elongated groove is provided on the vertical part. A second connecting pin is provided on the side wall of the flow channel 2 corresponding to the threaded position of the second connecting elongated groove. The second connecting pin passes through the second connecting elongated groove and threadedly engages with the side wall of the flow channel 2. The beneficial effect of this configuration is that the horizontal part of the L-shaped positioning block 6 engages with the first connecting elongated hole 51 of the connecting seat 5 through the first connecting pin, and the vertical part is connected to the side wall of the flow channel 2 through the second connecting elongated groove via the second connecting pin. This double connection forms a stable triangular support structure, effectively dispersing vibration and pressure during equipment operation and preventing the pressure bar from loosening or shifting. When the position of the pressure bar needs to be adjusted to accommodate materials of different specifications, the operator only needs to loosen the first and second connecting pins. Utilizing the movement space provided by the elongated holes and slots, millimeter-level fine adjustments can be made in both horizontal and vertical directions. After adjustment, the screws are tightened again, and the pressure bar can be precisely positioned, ensuring the stability and efficiency of conveying irregularly shaped parts.
[0021] As a further feature of this embodiment, a flow channel connector 43 is provided at the end of the flow channel 2. Fasteners 44 are respectively provided on both sides of the feed channel on the flow channel connector 43. A positioning pin is provided on the flow channel connector 43, and a sliding groove 441 is provided on the fastener 44 to engage with the positioning pin. The beneficial effects of this configuration are: in actual production, the flow channel connector 43 achieves a precise and flexible connection through the cooperation of the fasteners 44 and the positioning pin.

Operators can slide the fasteners 44 along the sliding groove to adjust the position and angle of the flow channel connector 43 according to the material characteristics and subsequent processing requirements, precisely controlling the discharge direction and speed. After fine-tuning, the fasteners 44 and the positioning pin are re-engaged, forming a reliable connection, ensuring that each irregularly shaped part can be discharged smoothly in an ideal posture, significantly improving processing accuracy and production efficiency.
