Description

Technical Field

[0001] The present disclosure relates to the field of bead - nailing machines, and particularly to a bead - nailing structure and an electric bead - nailing machine. Background Art

[0002] Nowadays, with the development of the clothing industry, people increasingly pursue the beauty and diversity of clothing. In addition to the requirements for the style of the clothing itself, there are also requirements for the accessories attached to the clothing. Therefore, it is necessary to bind some accessories such as diamonds, beads or plastic hardware buttons on the clothing to improve the taste and added value of the clothing. In this application, "clothing" has a broad meaning, not limited to clothes and trousers. In addition, it also includes shoes, socks, hats, gloves and handbags, etc. The existing bead - nailing machines convey beads from top to bottom and buttons from bottom to top, and then fix the buttons and beads together by the up - and - down impact of a cylinder. Using a cylinder for bead - nailing has the disadvantage of poor stability. Factors such as air - source pressure fluctuations and valve wear will significantly affect the positioning accuracy. Moreover, the cylinder can only be manually adjusted through a throttle valve, and it is difficult to accurately adjust the output thrust. Furthermore, the components of the cylinder are numerous and easily damaged, and the maintenance cost is high, which is not conducive to long - term use. Therefore, there is an urgent need for a bead - nailing machine with high precision, good stability and convenient adjustment.

[0003] Disclosure Content

[0004] The present disclosure provides a bead - nailing structure that no longer uses a cylinder for driving. Instead, a first push rod is driven by a motor to push the bead - punching rod downward to punch beads, and a second push rod is driven by the motor to push the nail - punching rod upward to punch nails. 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, and the bead - nailing error rate is low. The present disclosure also provides an electric bead - nailing machine.

[0005] To achieve the above - mentioned disclosure purpose, the present disclosure provides the following technical solutions:

[0006] A bead - nailing structure includes a bead - punching mechanism and a nail - punching mechanism. The bead - punching mechanism pushes the beads downward, and the nail - punching mechanism pushes the nails upward;

[0007] The bead - punching mechanism includes a first motor, a first transmission mechanism, a first push rod and a bead - 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 perform up - and - down reciprocating motion. The bead - punching seat is provided with a pressure rod and a bead - punching rod, and the pressure rod and the bead - punching rod are fixedly connected. When the first push rod pushes the pressure rod downward, the pressure rod drives the bead - punching rod downward. When the first push rod moves upward, a pressure - rod reset mechanism or a pressure - rod connection mechanism drives the pressure rod upward, and the pressure rod drives the bead - punching rod upward;

[0008] The punching nail mechanism includes a second motor, a second transmission mechanism, a second push rod, a punching nail rod, and a punching nail 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 and connecting rod. When the second transmission shaft rotates, the second cam or the second crank and connecting rod drives the second push rod to perform reciprocating up and down motion. The punching nail rod is movably installed on the punching nail seat, and the second push rod pushes the punching nail rod to reciprocate up and down along the punching nail seat.

[0009] Preferably, the inside of the bead punching rod is hollow to form a vacuum channel for adsorbing beads. The vacuum channel cooperates with the air suction mechanism to suck air, which can realize the bead punching rod briefly adsorbing the beads to be punched. The beads will not slide down along the bead punching track, and it is also convenient for the bead punching rod to be positioned.

[0010] Preferably, an air suction plate, an air suction pipe, a switching cylinder, and an air suction interface are further provided. Air inlet holes corresponding to the bead punching rods are provided on the air suction plate. The air suction pipe communicates with the air inlet holes and the vacuum channel. The switching cylinder is fixedly connected to the air suction interface. The switching cylinder controls the lifting of the air suction interface. When the first push rod is aligned with the working position of the bead punching rod, the switching cylinder controls the air suction interface to descend and communicate with the air inlet holes, and the air suction interface provides vacuum for the vacuum channel inside the bead punching rod.

[0011] Preferably, the bead punching seat is further provided with a slider and a slide rail. The bead punching rod is fixed on the slider. The slider is sleeved on the slide rail and slides along the slide rail. The bead punching rod moves up and down along the slide rail following the slider, and the situation of the bead punching rod being damaged due to the deviation of the bead punching rod will not occur.

[0012] Preferably, a switching motor, a lead screw, and a support seat are further provided. The first push rod is supported by the support seat. The support seat is fixed on the lead screw. There are multiple bead punching seats. The switching motor controls the translation of the lead screw. The lead screw drives the support seat to translate.

[0013] Preferably, a sensor is further included. An induction mechanism matching the sensor is provided on the first transmission shaft. The induction mechanism cooperates with the sensor to monitor the position of the first transmission shaft to avoid the first push rod colliding with the bead punching rod during horizontal movement.

[0014] Preferably, the pressure rod reset mechanism includes a spring and a limit mechanism. The limit mechanism is fixed on the pressure rod to limit the spring. When the first push rod pushes the pressure rod downward, the limit mechanism compresses the spring. When the pressure is withdrawn, the restoring force of the spring pushes the pressure rod to move upward and reset, thereby realizing the reset of the pressure rod. The pressure rod drives the bead punching rod to reset, so as to prepare for the next bead punching.

[0015] Preferably, the pressing rod connecting mechanism includes a connecting hook provided on the first push rod and a clamping groove provided on the pressing rod. The connecting hook is clamped into the clamping groove, and the first push rod directly drives the pressing rod to move up and down, thereby realizing the reset of the pressing rod.

It changes from pneumatic to electric, and the bead punching mechanism and the nail punching mechanism are driven by motors. The motors have the advantages of high precision, good stability and convenient adjustment. Since the bead nailing machine needs to impact the beads downward and the nails upward to nail the beads on the clothing when working, the motors can adjust the force and time according to different clothing categories, which can improve the applicable range of the bead nailing machine, and the precision and stability are relatively good, and it is not easy to have problems such as missed nailing and wrong nailing caused by precision control problems, which can improve the product experience and facilitate popularization and use.

[0020] 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 perform reciprocating up and down motion through the first cam or the first crank connecting rod.

[0046] An electric bead punching machine includes a bead punching mechanism.

[0047] The beneficial effects of the present disclosure are:

[0048] The present disclosure improves the disadvantages of the existing bead nailing machine in which both the bead punching mechanism and the nail punching mechanism use air cylinders, changes the pneumatic drive to an electric drive, and the bead punching mechanism and the nail punching mechanism are driven by motors. The motors have the advantages of high precision, good stability, and convenient adjustment. Since the bead nailing machine needs to impact the beads downward and the nails upward during operation to nail the beads on the clothing, the motors can adjust the force and time according to different clothing categories, which can improve the applicable range of the bead nailing machine, and has better precision and stability, and is not prone to problems such as missed nailing and wrong nailing caused by precision control problems, which can improve the product experience and facilitate popularization and use.

[0049] 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 perform reciprocating up and down movement through the first cam or the first crank and 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 bead punching rod 7 to move downward to perform bead 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 perform reciprocating up and down movement through the second cam or the second crank and connecting rod. The second push rod 8 is fixedly connected to the nail punching rod 9. When the second push rod 8 moves upward, the nail punching rod 9 follows the second push rod 8 to move upward to perform nail punching work. The nail punching mechanism and the bead punching mechanism cooperate to achieve bead nailing work.

[0050] The usage and working method of the present disclosure are as follows:

[0051] When the bead nailing machine is in use, the pattern to be nailed is set through the main control. Subsequently, 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 perform reciprocating up and down movement through the first cam or the first crank and 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 bead punching rod 7 to move downward, and the spring 18 is compressed. The bead punching rod 7 moves downward along the slide rail through the slider, the movable baffle is pushed open, and the beads are adsorbed on the vacuum channel of the bead punching rod 7 and move downward together with the bead punching rod 7 to complete the bead punching work. After the bead punching work is completed, when the first push rod 3 moves upward, the pressure rod 6 is no longer under pressure, and the restoring force of the spring 18 pushes the pressure rod 6 upward, and the pressure rod 6 drives the bead punching rod 7 to move upward. After the bead punching rod 7 moves upward along the slide rail through the slider and the pressure rod 6 drives the bead punching rod 7 to return to its original position, the beads enter the bead punching seat 5 and are supported by the movable baffle to complete the bead punching preparation;

[0052] 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 perform reciprocating up and down movement through the second cam or the second crank and connecting rod. When the second push rod 8 moves upward, the nail punching rod 9 follows the second push rod 8 to move upward, and the nails move upward together with the nail punching rod 9 to complete the nail punching work. After the nail punching work is completed, the second push rod 8 moves downward, and the nail punching rod 9 follows the second push rod 8 to move downward to complete the nail punching preparation;

[0053] When it is necessary to switch to other beads, the sensor 16 senses the position of the first transmission 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 interface 13 to rise. The switching motor drives the support base 15 to move left and right through the lead screw. The support base 15 drives the first push rod 3 to move left and right to align with the bead punching seat 5 corresponding to the target bead. Subsequently, the bead discharging member controls the bead to slide along the bead feeding track into the bead punching seat 5. At this time, the first push rod 3 is aligned with the pressure rod 6, and the suction interface 13 is aligned with the air inlet hole corresponding to the bead punching rod 7. The switching cylinder 12 controls the suction interface 13 to move downward to communicate with the air inlet hole, realizing the switching of different beads.

[0054] Therefore, for a bead nailing structure and an electric bead nailing machine provided by the present disclosure, the cylinder drive is no longer used. The first push rod 3 is driven by a motor to push the bead punching rod 7 downward to punch the bead, and the second push rod 8 is driven by a motor to push the nail punching rod 9 upward to punch the nail. The motor has the advantages of high precision, good stability, and convenient adjustment, can meet the impact force and stability requirements during bead nailing, and has a low bead nailing error rate.
