Not only is the work efficiency low, but it is also difficult to ensure that the quality of each button reaches a consistent standard, which often leads to quality problems such as uneven edges and different shapes. There is a machine on the market that can automatically close the buttons. It uses mechanical force to accurately control the force and shape to complete the curling of buttons, effectively saving labor.

[0030] like Figures 1 to 7 As shown, a high-stability button closing machine comprises a machine base 1, an automatic unloading mechanism 2 arranged on the machine base 1, a movable mold mechanism 3 and a static mold mechanism 4 arranged on the machine base 1, wherein the movable mold mechanism 3 of this embodiment comprises a movable mold base 31 fixedly arranged on the end surface of the machine base 1, two movable mold heads 32 arranged on one side of the movable mold base 31, and a first driving mechanism arranged on the machine base 1 for driving the movable mold head 32, and the static mold mechanism 4 comprises a static mold base 41 fixedly arranged on the peripheral side of the movable mold base 31, two movable mold heads 32 arranged on the static mold base 41 facing the movable mold head 32, and a first driving mechanism arranged on the machine base 1 for driving the movable mold head 32. A static die head 42 on the side and a solid material component 43 covered on the static die head 42 for fixing the buttons on the static die head 42, and a supporting base plate 6 is arranged between the dynamic die head 32 and the static die head 42, and the supporting base plate 6 is provided with two unloading rails 62 connected with the automatic unloading mechanism 2 on the side facing the static die head 42, and two pusher blocks 61 slidably installed on the end surface of the supporting base plate 6 and arranged at the rear end of the unloading rails 62 for pushing the buttons into the static die head 42, and a second driving mechanism for driving the pusher block 61 is also provided on the machine base 1.

[0031] The automatic unloading mechanism 2 of this embodiment is a centrifugal vibrating plate installed on the frame, and is connected to two unloading tracks 62 set on the end surface of the support base plate 6 for feeding; and the two sides of the support base plate 6 are respectively provided with a static mold mechanism 4 and a dynamic mold mechanism 3 that cooperates with it to close the edge and curl the edge, and a pusher block 61 is provided at the bottom of the support base plate 6 to receive the buttons at the tail end outlet of the unloading track 62 and be driven by the first drive mechanism to push them to the static mold mechanism 4. The cooperation between the automatic unloading mechanism 2 and the pusher block 61 driven and controlled by the second drive mechanism realizes the fully automated processing of buttons from feeding to feeding to the static mold, greatly improving production efficiency. And a solid material assembly 43 is provided at each static die head 42 of the static mold mechanism 4, which can receive and fix the semi-finished buttons pushed by the pusher block 61 to the static die head 42 to prevent displacement during the closing process of the dynamic mold, resulting in affecting the closing accuracy.

[0032] like Figure 5As shown, the solid material assembly 43 of this embodiment includes a fixed block 431 fixed on the static die seat 41 and a central through hole 432 provided at the center of the fixed block 431. The static die head 42 is inserted into the central through hole 432. The central through hole 432 is provided with guide grooves 433 that are connected to the push block 61 on both sides of the horizontal direction, and clamping blocks 434 are provided on both sides of the vertical direction. The adjacent ends of the two clamping blocks 434 are provided with arc surfaces 4341, and the two clamping blocks 434 together form a closing station 434. The fixed block 431 is fixedly mounted on the static die head 42, and the central through hole 432 ensures the accurate positioning of the static die head 42, and does not leave space for subsequent closing. Guide grooves 433 are provided on both sides of the central through hole 432 in the horizontal direction, and form a seamless connection with the push block 61, so as to ensure that the button can smoothly transition along the predetermined path when being pushed to the position of the static die head 42, reduce the risk of the button shifting during the movement, and improve the accuracy of feeding. Clamping blocks 434 are arranged on both vertical sides of the central through hole 432, and arc surfaces 4341 are arranged at adjacent ends of the two clamping blocks 434, which cooperate with the round button to prevent it from being blocked; and a closing station 434 is constructed at the center to cooperate with the static die head 42 in the central through hole 432 for high-precision closing.

[0033] like Figure 1 As shown, the first driving mechanism of this embodiment includes a driving motor 51 arranged on one side of the machine base 1, a rotating main shaft 52 connected to the driving motor 51, two first eccentric wheels 53 installed on the rotating main shaft 52, and a first connecting rod 54 fixed with the first eccentric wheel 53 at one end, and the other end of the first connecting rod 54 is connected to the movable die head 32. The driving motor 51 is used as a power source. Through direct connection with the rotating main shaft 52, the speed and torque of the motor can be directly converted into the rotational motion of the rotating main shaft 52. Two first eccentric wheels 53 are installed on the rotating main shaft 52, so that each movable die head 32 can be independently driven. The rotation of the eccentric wheel drives the connecting rod to move, which is then converted into a linear reciprocating motion of the movable die head 32, realizing an effective conversion from rotational motion to linear motion. The movable die head 32 is driven stably and accurately. During the closing process, the movable die head 32 can reciprocate according to a preset trajectory and cooperate with the static die head 42 to complete the closing and curling of the button. Furthermore, the phase difference between the two first eccentric wheels 53 is 180 degrees. The 180-degree phase difference design allows the two movable die heads 32 to work alternately, that is, while one movable die head 32 completes the closing operation, the other movable die head 32 is ready for the next cycle. The synchronous but opposite-phase motion mode enables the equipment to process more buttons per unit time, significantly improving production efficiency and capacity.

[0034] like Figure 1 and Figure 2 , Figure 3As shown, the second driving mechanism of this embodiment includes a turbine 55 arranged at the tail end of the rotating main shaft 52, a worm 56 arranged at the other side of the machine base and meshingly connected to the turbine 55, a second eccentric wheel 58 arranged at the tail end of the worm wheel 56, and a crank connecting rod 57 connected to the second eccentric wheel 58 at one end, and a sliding rod 65 is transversely fixed on the side of the support base plate 6 facing away from the push block 61, a driving block 66 and connecting blocks 64 arranged on both sides of the driving block 66 and connected to the driving block 66 are sleeved on the sliding rod 65, and a buffer spring 67 is also provided between the driving block 66 and the connecting block 64, the other end of the crank connecting rod 57 is fixedly connected to the driving block 66 and can drive the driving block 66 to reciprocate laterally, and sliding grooves 63 are symmetrically provided on both sides of the bottom of the support base plate 6, and the connecting block 64 passes through the sliding grooves 63 and is fixedly connected to the push block 61. The second driving mechanism adopts a self-locking turbine 55 and a worm 56 transmission, that is, when the worm 56 stops rotating, the turbine 55 will not reverse automatically, which can ensure that the pusher block 61 can remain stable in the non-driving state and avoid the accidental movement of the button during the conveying process. By setting a second eccentric wheel 58 at the tail end of the worm 56 and connecting the crank connecting rod 57, the rotary motion is converted into a linear reciprocating motion, and the sliding rod 65 fixedly arranged laterally on the side of the supporting base plate 6 facing away from the pusher block 61 forms a stable guide system with the driving block 66 sleeved thereon. The sliding rod 65 ensures that the driving block 66 and the connecting block 64 driven by the crank connecting rod 57 can move linearly along the preset path, reducing the deviation during the movement. The two connecting blocks 64 arranged at the bottom of the driving block 66 are connected to the pusher block 61 through the slide groove 63, driving the two pusher blocks 61 to perform high-precision and automatic lateral reciprocating motion. A buffer spring 67 is arranged between the driving block 66 and the connecting block 64 to absorb the impact and vibration during the movement.

[0035] like Figure 6 to Figure 7 As shown, the front side of the push block 61 of this embodiment is provided with a material receiving slot 611, which is located at the bottom of the tail end of the unloading track 62 and can be displaced to the closing station 434, and a mounting tail slot 612 is provided at one end of the material receiving slot 611, and a material blocking member 613 is movably provided on the back side of the push block 61, and one end of the material blocking member 613 extends into the mounting tail slot 612. The material receiving slot 611 provided on the front side of the push block 61 and the material blocking member 613 movably provided on the back side of the push block 61 are just located at the bottom of the tail end of the unloading track 62, ensuring that the buttons are smoothly transferred from the unloading track 62 to the push block 61, reducing the risk of buttons falling or getting stuck during transportation. When the push block 61 reaches the closing station 434, the material blocking member 613 is moved downward to avoid the buttons being brought out.

[0036] In summary, the beneficial effects of this embodiment are as follows: this embodiment uses a centrifugal vibration plate as the automatic unloading mechanism 2, which is seamlessly connected with the unloading track 62 on the supporting substrate 6 to achieve continuous feeding of buttons. With the precise control of the push block 61 and the second driving mechanism, the buttons can be stably and accurately pushed to the static die head 42, which greatly improves the production efficiency. The receiving slot 611 and the material stopper 613 on the push block 61 ensure the precise receiving and stable pushing of the buttons, and the material stopper 613 is retracted and moved under force to avoid bringing the buttons out; the solid material assembly 43 composed of the fixed block 431, the central perforation 432, the guide groove 433 and the clamping block 434 provides stable support for the buttons, ensuring the precise positioning of the buttons on the static die head 42 to improve the closing accuracy. The two moving die heads 32 driven by the first driving mechanism, combined with the design of 180-degree phase difference, realize the alternating operation of the two heads, which significantly improves the production efficiency of the equipment.

[0037] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
