[0029] Embodiment 1
[0030] Refer Figures 1 to 4 As shown, this embodiment discloses a specific implementation manner of an intermittent tape cutting device.
[0031] This embodiment provides an intermittent tape cutting device. Refer Figures 1 to 4As shown in the figure, it includes an upper die assembly 1, a lower die assembly 2, a lower die support assembly 3, a ratchet drive assembly 4, a ratchet assembly 5, and a cutting assembly 6. The ratchet drive assembly 4 includes an L-shaped support plate 41, a lever 42 and a first return spring 43 provided on the L-shaped support plate 41. A first inclined surface 421 is provided at the end of the lever 42, and the L-shaped support plate 41 is installed on the lower die support assembly 3. The ratchet assembly 5 includes symmetrically arranged brackets 51, a transmission shaft 52, a first ratchet 53, a second ratchet 54, and a backstop tooth 55. The backstop tooth 55 is installed outside the bracket 51. The first ratchet 53 is evenly provided with n first transmission teeth 531. The first transmission teeth 531 cooperate with the first inclined surface 421, and the backstop tooth 55 cooperates with the first transmission teeth 531. The second ratchet 54 is provided with a second transmission tooth 541, and the second ratchet 54 is arranged on the transmission shaft 52. The cutting assembly 6 includes a push rod 61, a second return spring 62, and a punch assembly 63. The second ratchet 54 cooperates with the push rod 61. A slant chute 611 is provided at the end of the push rod 61, and a slant slider 631 is provided on the top plate of the punch assembly 63. The slant slider 631 cooperates with the slant chute 611.
[0032] Specifically, referring to Figures 1 to 4 As shown in the figure, the upper die assembly 1 includes an upper die base 11, an upper backing plate 12, and an upper clamping plate 13. The lower die assembly 2 includes a stop plate 21 and a stripper plate 22. The lower die support assembly 3 includes a lower template 33, a lower backing plate 31, and a lower die base 32. The descending process of the upper die assembly 1 includes a first descending position and a second descending position. Figure 2 Figure 7 is a schematic diagram of the open die state between the upper die assembly 1, the lower die assembly 2, and the lower die support assembly 3. Figure 3 Figure 9 is a schematic diagram of the lower die assembly 2 against the lower die support assembly 3. At this time, the upper die assembly 1 is in the first descending position. Figure 4 Figure 11 is a schematic diagram of the upper die assembly 1 against the lower die assembly 2. At this time, the upper die assembly 1 is in the second descending position. When the upper die assembly 1 is in the first descending position, referring to Figure 3 As shown in the figure, the lower die assembly 2 abuts against the lower die support assembly 3. Specifically, the stripper plate 22 abuts against the lower template 33. During this process, the first inclined surface 421 drives the first transmission teeth 531 to rotate a tooth pitch. The rotation angle of a tooth pitch is 360° / n, where n is the number of the first transmission teeth 531, and the first ratchet 53 is engaged by the backstop tooth 55 to prevent the first ratchet 53 from reversing. When the upper die assembly 1 is in the second descending position, referring to Figure 4As shown, the upper die assembly 1 presses against the lower die assembly 2. Specifically, the upper clamping plate 13 presses against the stop plate 21. Since there is only one second transmission gear 541, every time the first transmission gear 531 rotates by one pitch, the first transmission gear 531 drives the second transmission gear 541 to rotate by one pitch through the transmission shaft 52. When the first ratchet wheel 53 rotates one circle, the second transmission gear 541 presses against and pushes the push rod 61 to move. The inclined surface slider 631 and the inclined surface chute 611 cooperate to drive the punch assembly 63 to move downward and cut the strip 7. The punch assembly 63 includes a fixed block 632 and a punch 633. The inclined surface slider 631 is arranged at the top of the fixed block 632. To maintain the stable rise or fall of the punch assembly 63, two inclined surface sliders 631 are arranged side by side, and correspondingly, two inclined surface chutes 611 are also arranged correspondingly. Through the cooperation of the inclined surfaces of the inclined surface chute 611 and the inclined surface slider 631, the punch 633 is driven to rise or fall, realizing the cutting of the strip 7.
[0033] In a preferred embodiment, the first ratchet wheel 53 is evenly provided with five to ten first transmission teeth 531. Taking ten first transmission teeth 531 as an example, the first ratchet wheel 53 is evenly provided with ten first transmission teeth 531. The upper die assembly 1 is successively in the first descending position and the second descending position, which is the die closing process. In this process, the lever 42 pushes the first ratchet wheel 53 to rotate by one pitch through the first transmission tooth 531. Synchronously, the strip advances by one step. After closing the die ten times repeatedly, the second ratchet wheel 54 drives the second transmission gear 541 to rotate one circle. At the eleventh die closing, referring to Figure 4 the arrow direction in, the second transmission gear 541 exactly drives the push rod 61 to move, and then through the cooperation of the inclined surfaces of the inclined surface chute 611 and the inclined surface slider 631, the punch 633 is driven to descend and complete a strip cutting. According to the above process, it is carried out reciprocally to realize efficient intermittent strip cutting. When it is necessary to increase or shorten the cutting distance of the strip, it can be realized by replacing the first ratchet wheel 53 with different numbers of teeth, increasing the versatility of the intermittent strip cutting device.
