Description

Technical Field

[0001] This disclosure relates to the field of bead-attaching machines, specifically to a bead-attaching structure and an electric bead-attaching machine. Background Technology

[0002] Today, with the development of the clothing industry, people are increasingly pursuing the aesthetics and diversity of clothing. Besides requirements for the style of the clothing itself, they also have demands for the accessories attached to it. This necessitates the use of accessories such as diamonds, beads, or plastic hardware buttons to enhance the taste and added value of clothing. In this application, "clothing" is used in a broad sense, not limited to clothes and trousers, but also including shoes, socks, hats, gloves, and handbags. Existing beading machines use a method where beads are fed from top to bottom and buttons are fed from bottom to top, then a cylinder impacts the buttons to fix them to the beads. However, using a cylinder for beading has the disadvantage of poor stability. Fluctuations in air pressure and valve wear can significantly affect positioning accuracy. Furthermore, the cylinder can only be manually adjusted via a throttle valve, making it difficult to precisely adjust the output thrust. Moreover, the cylinder has many components that are easily damaged, resulting in high maintenance costs and making it unsuitable for long-term use. Therefore, there is an urgent need for a beading machine with high precision, good stability, and convenient adjustment. Utility Model Content

[0003] This disclosure provides a bead-nailing structure that eliminates the need for cylinder drive. Instead, a motor drives a first push rod to push a punch rod downwards to strike the bead, and a motor drives a second push rod to push a punch rod upwards to strike the bead. The motor has the advantages of high precision, good stability, and convenient adjustment, which can meet the impact force and stability requirements during bead nailing. The bead nailing error rate is low. An electric bead nailing machine is also provided.

[0004] To achieve the aforementioned objectives, this disclosure provides the following technical solution:

[0005] A bead-pinning structure includes a bead-punching mechanism and a pin-punching mechanism, wherein the bead-punching mechanism pushes the bead downward and the pin-punching mechanism pushes the pin upward;

[0006] The ball-punching mechanism includes a first motor, a first transmission mechanism, a first push rod, and a ball-punching seat. The first transmission mechanism includes a first transmission shaft. The first motor is connected to and drives the first transmission shaft to rotate through a first synchronization mechanism. The first transmission shaft is connected to the first push rod through a first cam or a first crank-connecting rod. When the first transmission shaft rotates, the first cam or the first crank-connecting rod drives the first push rod to reciprocate up and down. The ball-punching seat is provided with a pressure rod and a ball-punching rod. The pressure rod and the ball-punching rod are fixedly connected. When the first push rod pushes the pressure rod downward, the pressure rod drives the ball-punching rod to move downward. When the first push rod moves upward, the pressure rod reset mechanism or the pressure rod connecting mechanism drives the pressure rod to move upward, and the pressure rod drives the ball-punching rod to move upward.

[0007] The punching mechanism includes a second motor, a second transmission mechanism, a second push rod, a punch rod, and a punch seat. The second transmission mechanism includes a second transmission shaft. The second motor is connected to and drives the second transmission shaft to rotate through a second synchronization mechanism. The second transmission shaft is connected to the second push rod through a second cam or a second crank connecting rod. When the second transmission shaft rotates, the second cam or the second crank connecting rod drives the second push rod to reciprocate up and down. The punch rod is movably mounted on the punch seat. The second push rod pushes the punch rod to reciprocate up and down along the punch seat.

[0008] Preferably, the inside of the punch rod is hollow to form a vacuum channel for adsorbing the beads. The vacuum channel and the suction mechanism work together to allow the punch rod to briefly adsorb the beads to be punched, so that the beads will not slip down the punch rod track and the punch rod is easy to position.

[0009] Preferably, the device also includes a suction plate, a suction pipe, a switching cylinder, and a suction interface. The suction plate has an air inlet corresponding to the ball punch rod. The suction pipe connects the air inlet and the vacuum channel. The switching cylinder is fixedly connected to the suction interface. The switching cylinder controls the lifting and lowering of the suction interface. When the first push rod is aligned with the working position of the ball punch rod, the switching cylinder controls the suction interface to descend and connect to the air inlet. The suction interface provides a vacuum to the vacuum channel inside the ball punch rod.

[0010] Preferably, the ball bearing holder is also provided with a slider and a slide rail. The ball bearing rod is fixed on the slider, the slider is sleeved on the slide rail and slides along the slide rail. The ball bearing rod moves up and down along the slide rail following the slider, so that the ball bearing rod will not be deviated and damaged.

[0011] Preferably, a switching motor, a lead screw, and a support base are also provided. The first push rod is supported by the support base, which is fixed on the lead screw. Multiple bead punching seats are provided. The switching motor controls the lead screw to move horizontally, the lead screw drives the support base to move horizontally, and the support base drives the first push rod to move horizontally, thereby aligning with different bead punching seats. This allows for the application of beads of different specifications onto the fabric, making the bead patterns more diverse.

[0012] Preferably, it also includes a sensor, and a sensing mechanism matching the sensor is provided on the first drive shaft. The sensing mechanism works with the sensor to monitor the position of the first drive shaft and prevent the first push rod from colliding with the ball punch rod when it moves horizontally.

[0013] Preferably, the pressure rod reset mechanism includes a spring and a limiting mechanism. The limiting mechanism is fixed on the pressure rod to limit the spring. When the first push rod pushes the pressure rod downward, the limiting mechanism compresses the spring. When the pressure is removed, the restoring force of the spring pushes the pressure rod upward to reset, thereby realizing the pressure rod reset. The pressure rod drives the ball punch rod to reset, thereby preparing for the next ball punch.

[0014] Preferably, the pressure rod connecting mechanism includes a connecting hook disposed on the first push rod and a slot disposed on the pressure rod. The connecting hook is engaged in the slot, and the first push rod directly drives the pressure rod to move up and down, thereby realizing the pressure rod reset. The pressure rod drives the ball punch rod to reset, thereby preparing for the next ball punching.

[0015] Preferably, the first motor and the second motor are servo motors, stepper motors, or frequency converter-controlled motors, which have the advantages of high precision, good stability, and convenient adjustment.

[0016] An electric bead-attaching machine includes a bead-attaching mechanism.

[0017] The beneficial effects of this disclosure are as follows:

[0018] This disclosure improves upon the shortcomings of existing bead-attaching machines where both the bead-attaching and nail-attaching mechanisms use cylinders. It replaces pneumatic with electric power, using a motor to drive both mechanisms. Motors offer advantages such as high precision, good stability, and convenient adjustment. Since the bead-attaching machine requires the beads to impact downwards and the nails to impact upwards to attach the beads to the garment, the motor can adjust the force and time for different garment types, thus expanding the machine's applicability. Furthermore, it offers better precision and stability, reducing the likelihood of missed or incorrect nailing due to precision control issues. This enhances the user experience and facilitates widespread adoption.

[0019] Secondly, the first motor and the first synchronization mechanism drive the first transmission shaft to rotate. The first transmission shaft drives the first push rod to reciprocate up and down through the first cam or the first crank connecting rod. The first push rod is aligned with the pressure rod. When the first push rod moves downward, the pressure rod follows the first push rod downward, and the pressure rod drives the punch rod downward to perform the punching operation. The second motor and the second synchronization mechanism drive the second transmission shaft to rotate. The second transmission shaft drives the second push rod to reciprocate up and down through the second cam or the second crank connecting rod. The second push rod and the punch rod are fixedly connected. When the second push rod moves upward, the punch rod follows the second push rod upward to perform the punching operation. The punching mechanism and the punching mechanism work together to achieve the punching operation. Attached Figure Description

[0034] A bead-pinning structure includes a bead-punching mechanism and a pin-punching mechanism, wherein the bead-punching mechanism pushes the bead downward and the pin-punching mechanism pushes the pin upward;

[0035] The ball-punching mechanism includes a first motor 1, a first transmission mechanism, a first push rod 3, and a ball-punching seat 5. The first transmission mechanism includes a first transmission shaft 4. The first motor 1 is connected to and drives the first transmission shaft 4 to rotate through a first synchronization mechanism 2. The first transmission shaft 4 is connected to the first push rod 3 through a first cam or a first crank connecting rod. When the first transmission shaft 4 rotates, the first cam or the first crank connecting rod drives the first push rod 3 to reciprocate up and down. The ball-punching seat 5 is provided with a pressure rod 6 and a ball-punching rod 7. The pressure rod 6 and the ball-punching rod 7 are fixedly connected. When the first push rod 3 pushes the pressure rod 6 downward, the pressure rod 6 drives the ball-punching rod 7 to move downward. When the first push rod 3 moves upward, the pressure rod 6 reset mechanism or the pressure rod 6 connecting mechanism drives the pressure rod 6 to move upward, and the pressure rod 6 drives the ball-punching rod 7 to move upward.

[0036] The punching mechanism includes a second motor 20, a second transmission mechanism, a second push rod 8, a punch rod 9, and a punch seat 22. The second transmission mechanism includes a second transmission shaft 14. The second motor 20 is connected to and drives the second transmission shaft 14 to rotate through a second synchronization mechanism 21. The second transmission shaft 14 is connected to the second push rod 8 through a second cam or a second crank connecting rod. When the second transmission shaft 14 rotates, the second cam or the second crank connecting rod drives the second push rod 8 to reciprocate up and down. The punch rod 9 is movably mounted on the punch seat 22. The second push rod 8 pushes the punch rod 9 to reciprocate up and down along the punch seat 22.

[0037] The punch rod 7 has a hollow interior forming a vacuum channel for adsorbing the beads. The vacuum channel and the suction mechanism work together to allow the punch rod 7 to briefly adsorb the beads to be punched, preventing the beads from slipping down the punching track and facilitating the positioning of the punch rod 7.

[0038] It is also equipped with a suction plate 10, a suction pipe 11, a switching cylinder 12, and a suction interface 13. The suction plate 10 is provided with an air inlet corresponding to the ball punch rod 7. The suction pipe 11 connects the air inlet and the vacuum channel. The switching cylinder 12 is fixedly connected to the suction interface 13. The switching cylinder 12 controls the lifting and lowering of the suction interface 13. When the first push rod 3 is aligned with the working position of the ball punch rod 7, the switching cylinder 12 controls the suction interface 13 to descend and connect to the air inlet. The suction interface 13 provides a vacuum for the vacuum channel inside the ball punch rod 7.

[0039] The ball bearing holder 5 is also equipped with a slider and a slide rail. The ball bearing rod 7 is fixed on the slider, the slider is sleeved on the slide rail and slides along the slide rail. The ball bearing rod 7 moves up and down along the slide rail with the slider, so that the ball bearing rod 7 will not be deviated and damaged.

[0040] It is also equipped with a switching motor, a lead screw, and a support base 15. The first push rod 3 is supported by the support base 15, which is fixed on the lead screw. Multiple ball punching seats 5 are provided. The switching motor controls the lead screw to move, the lead screw drives the support base 15 to move, and the support base 15 drives the first push rod 3 to move, thereby aligning with different ball punching seats 5. This allows different sizes of beads to be punched on the fabric, making the bead patterns more diverse.

[0041] It also includes a sensor 16, and a sensing mechanism 17 matching the sensor 16 is provided on the first drive shaft 4. The sensing mechanism 17 works with the sensor 16 to monitor the position of the first drive shaft 4 and prevent the first push rod 3 from colliding with the ball punch rod 7 when it moves horizontally.

[0042] The pressure rod 6 reset mechanism includes a spring 18 and a limiting mechanism 19. The limiting mechanism 19 is fixed on the pressure rod 6 to limit the spring 18. When the first push rod 3 pushes the pressure rod 6 downward, the limiting mechanism 19 compresses the spring 18. When the pressure is released, the restoring force of the spring 18 pushes the pressure rod 6 upward to reset, thereby realizing the reset of the pressure rod 6. The pressure rod 6 drives the ball punch rod 7 to reset, thereby preparing for the next ball punch.

[0043] The connecting mechanism of the pressure rod 6 includes a connecting hook on the first push rod 3 and a slot on the pressure rod 6. The connecting hook is engaged in the slot, and the first push rod 3 directly drives the pressure rod 6 to move up and down.

[0044] The first motor 1 and the second motor 20 are servo motors, stepper motors, or frequency converter-controlled motors, which have the advantages of high precision, good stability, and convenient adjustment.

[0045] An electric bead-attaching machine includes a bead-attaching mechanism.

[0046] The beneficial effects of this disclosure are as follows:

[0047] This disclosure improves upon the shortcomings of existing bead-attaching machines where both the bead-attaching and nail-attaching mechanisms use cylinders. It replaces pneumatic with electric power, using a motor to drive both mechanisms. Motors offer advantages such as high precision, good stability, and convenient adjustment. Since the bead-attaching machine requires the beads to impact downwards and the nails to impact upwards to attach the beads to the garment, the motor can adjust the force and time for different garment types, thus expanding the machine's applicability. Furthermore, it offers better precision and stability, reducing the likelihood of missed or incorrect nailing due to precision control issues. This enhances the user experience and facilitates widespread adoption.

[0048] Secondly, the first motor 1 and the first synchronization mechanism 2 drive the first transmission shaft 4 to rotate. The first transmission shaft 4 drives the first push rod 3 to reciprocate up and down through the first cam or the first crank connecting rod. When the first push rod 3 moves downward, the pressure rod 6 follows the first push rod 3 to move downward, and the pressure rod 6 drives the punch rod 7 to move downward to perform the punching work. The second motor 20 and the second synchronization mechanism 21 drive the second transmission shaft 14 to rotate. The second transmission shaft 14 drives the second push rod 8 to reciprocate up and down through the second cam or the second crank connecting rod. The second push rod 8 and the punch rod 9 are fixedly connected. When the second push rod 8 moves upward, the punch rod 9 follows the second push rod 8 to move upward to perform the punching work. The punching mechanism and the punching mechanism cooperate to realize the punching work.

[0049] The usage and working methods of this disclosure are as follows:

[0050] When the bead-attaching machine is in use, the pattern to be attached is set through the main control. Then, the first motor 1 drives the first transmission shaft 4 to rotate through the first synchronization mechanism 2. The first transmission shaft 4 drives the first push rod 3 to move up and down through the first cam or the first crank connecting rod. When the first push rod 3 moves downward, the pressure rod 6 moves downward with the first push rod 3. The pressure rod 6 drives the punch rod 7 to move downward. The spring 18 is compressed. The punch rod 7 moves downward along the slide rail through the slider. The movable baffle is pushed open. The bead is attracted to the vacuum channel of the punch rod 7 and moves downward with the punch rod 7. After the punching work is completed, when the first push rod 3 moves upward, the pressure rod 6 is no longer under pressure. The restoring force of the spring 18 pushes the pressure rod 6 to move upward. The pressure rod 6 drives the punch rod 7 to move upward. The punch rod 7 moves upward along the slide rail through the slider. After the pressure rod 6 drives the punch rod 7 to reset, the bead enters the punching seat 5 and is supported by the movable baffle, completing the punching preparation.

[0051] The second motor 20 drives the second transmission shaft 14 to rotate through the second synchronization mechanism 21. The second transmission shaft 14 drives the second push rod 8 to reciprocate up and down through the second cam or the second crank connecting rod. When the second push rod 8 moves upward, the punch rod 9 moves upward with the second push rod 8, and the nail moves upward together with the punch rod 9. After the punching work is completed, the second push rod 8 moves downward, and the punch rod 9 moves downward with the second push rod 8, thus completing the punching preparation.

[0052] When it is necessary to switch to other beads, sensor 16 senses the position of the first drive shaft 4 to ensure that the first push rod 3 will not collide with the pressure rod 6. The switching cylinder 12 controls the suction port 13 to rise. The switching motor drives the support seat 15 to move left and right through the lead screw. The support seat 15 drives the first push rod 3 to move left and right to align with the punch seat 5 corresponding to the target bead. Then the bead ejector controls the bead to slide down along the bead feeding track into the punch seat 5. At this time, the first push rod 3 is aligned with the pressure rod 6, and the suction port 13 is aligned with the air inlet corresponding to the punch rod 7. The switching cylinder 12 controls the suction port 13 to move downward to connect with the air inlet, realizing the switching of different beads.

[0053] Therefore, the bead-nailing structure and electric bead-nailing machine provided in this disclosure no longer use cylinder drive. Instead, the first push rod 3 is driven by a motor, which pushes the bead-punching rod 7 downward to punch the bead. The second push rod 8 is driven by a motor to push the bead-punching rod 9 upward to punch the bead. The motor has the advantages of high precision, good stability and convenient adjustment, which can meet the impact force and stability requirements when nailing beads, and the bead-nailing error rate is low.
