DETAILED DESCRIPTION

[0023] The following will be combined with the attached embodiment of the present utility model Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] As shown in the figure, a die-cutting mechanism of a double-sided tape die-cutting machine includes a frame 1, a drive seat 2 and a die-cutting knife 3. The drive seat 2 can be longitudinally slidably arranged on the frame 1 and is transmission-connected to the driving device, and also includes a knife seat 4 with a T-shaped cross-section. The die-cutting knife 3 is fixedly connected to the lower surface of the knife seat 4, and a mounting groove 21 matching the knife seat 4 and penetrating the drive seat 2 at one end is provided on the lower surface of the drive seat 2. A rotating shaft 41 is formed on both sides of the end of the knife seat 4. The knife seat 4 is inserted into the mounting groove 21 through the notch of the mounting groove 21. The notch of the mounting groove 21 is fixedly connected with two limit blocks 5 respectively located on both sides of the knife seat 4 and opposite to the rotating shaft 41. An axial groove 51 communicating with the mounting groove 21 and matching the rotating shaft 41 is provided in the limit block 5. A locking component for limiting the knife seat 4 from sliding in the mounting groove 21 is provided on the drive seat 2.

[0025] Specifically, the locking assembly includes a locking rod 6 and a spring 7. A first locking hole 22 that is connected to the mounting groove 21 and matches the locking rod 6 is provided on the upper surface of the driving seat 2. A second locking hole 42 that matches the locking rod 6 and can be aligned with the first locking hole 22 is provided on the upper surface of the knife seat 4. The cross-section of the locking rod 6 is T-shaped and a locking block 61 is formed at the small end. A first locking groove 23 that is connected to the first locking hole 22 and matches the locking block 61 is provided on the lower surface of the driving seat 2. A second locking groove 43 that is connected to the second locking hole 42 and matches the locking block 61 is provided on the upper surface of the knife seat 4. A locking cavity 44 that is connected to the second locking hole 42 and the second locking groove 43 and can be used for the locking block 61 to rotate is provided in the knife seat 4. The locking rod 6 is inserted into the first locking hole 22. The spring 7 is sleeved on the locking rod 6 and is located between the upper surface of the driving seat 2 and the locking block 61. When the second locking hole 42 is aligned with the first locking hole 22, the second locking groove 43 is aligned with the first locking groove 23, and the locking rod 6 is pressed downward, driving the locking block 61 to slide out of the first locking groove 23 and enter the second locking groove 43. When the locking block 61 continues to slide and leaves the second locking groove 43 and enters the locking cavity 44, the locking rod 6 can be rotated to drive the locking block 61 to rotate in the locking cavity 44. When the locking block 61 rotates to a position deviating from the second locking groove 43, the locking rod 6 drives the locking block 61 to press against the top wall of the locking cavity 44 under the action of the spring 7, so that the locking block 61 is kept in the locking cavity 44, thereby keeping the locking rod 6 in the second locking hole 42. The sliding of the knife seat 4 in the mounting groove 21 is limited by the action of the locking rod 6, so that the knife seat 4 is kept in the mounting groove 21 and the knife seat 4 is fixedly connected to the driving seat 2.

[0026] Specifically, a plurality of upright support columns 8 are fixedly connected to the frame 1, and a transmission shaft 9 which is rotatably provided on the frame 1 and is transmission-connected to a motor provided on the frame 1, the drive seat 2 is penetrated through the support columns 8 and the drive seat 2 is transmission-connected to the transmission shaft 9 through a transmission assembly, and the transmission assembly comprises a transmission rod 10, a transmission ring 11 and a transmission plate 12, the upper end of the transmission rod 10 is fixedly connected to the drive seat 2, and the lower end is hinged to the transmission ring 11, the outer diameter of the transmission plate 12 matches the inner diameter of the transmission ring 11 and the transmission plate 12 is eccentrically connected to the transmission shaft 9, and the transmission ring 11 is sleeved on the transmission plate 12.

[0027] In the above embodiment, the motor drives the transmission shaft 9 to rotate, the transmission shaft 9 drives the transmission disk 12 to rotate eccentrically, the transmission disk 12 drives the transmission ring 11 to reciprocate longitudinally, the transmission ring 11 drives the transmission rod 10 and then drives the drive seat 2 to reciprocate longitudinally, so that the drive seat 2 drives the knife seat 4 and drives the die-cutting knife 3 to reciprocate longitudinally on the support column 8, thereby performing high-speed die-cutting operations on the double-sided tape passing under the die-cutting knife 3. When the die-cutting knife 3 needs to be replaced, the locking rod 6 is rotated to drive the locking block 61 to rotate, so that the locking block 61 is rotated to a position aligned with the second locking groove 43. At this time, the locking rod 6 drives the locking block 61 to slide into the second locking groove 43 under the action of the spring 7 and continues to slide in the second locking groove 43 and leaves the second locking groove 43 to enter the first locking groove. 23, at this time, the locking rod 6 is completely withdrawn from the second locking hole 42 and the limit of the knife seat 4 sliding in the installation groove 21 is released. Pulling the end of the knife seat 4 can drive the knife seat 4 to slide in the installation groove 21. When the knife seat 4 slides to the rotating shaft 41 at its end and enters the shaft groove 51, the knife seat 4 is flipped up along the rotating shaft 41 to expose the die-cutting knife 3 fixedly connected to the lower surface of the knife seat 4, and the die-cutting knife 3 can be replaced. After the replacement is completed, the knife seat 4 is flipped down and slides into the installation groove 21, and then the knife seat 4 is locked by the locking assembly. It can be seen that the die-cutting mechanism of this double-sided tape die-cutting machine can die-cut the double-sided tape at a high speed, and the die-cutting knife 3 can be replaced quickly and conveniently to meet different production needs, and has better applicability.

[0028] Preferably, a third locking groove 45 matching the locking block 61 is provided on the top wall of the locking cavity 44. When the locking assembly applies a sliding limit to the knife holder 4 and rotates the locking block 61 in the locking cavity 44, the locking block 61 is rotated to a position aligned with the third locking groove 45 and is snapped into the third locking groove 45 under the action of the spring 7, so that the locking block 61 and the locking rod 6 will not be vibrated and rotate in the locking cavity 44 by themselves, thereby enhancing the stability of the locking block 61 in the locking cavity 44, and also enhancing the stability of the sliding limit applied by the locking assembly to the knife holder 4, thereby ensuring the stability of the die-cutting mechanism during the die-cutting operation.

[0029] Preferably, a handle 62 is fixedly connected to the large end of the locking rod 6 , and the handle 62 is convenient for pressing and rotating the locking rod 6 .

[0030] Preferably, a handle 46 is fixedly connected to the side end of the knife holder 4 , and the handle 46 facilitates pulling the knife holder 4 to slide in the installation groove 21 .

[0031] Preferably, four support columns 8 are arranged in a rectangular array, four groups of transmission components are provided and are respectively located on one side of the support column 8, two transmission shafts 9 are provided, and the transmission plates 12 of the four groups of transmission components are respectively connected to the two ends of the two transmission shafts 9, and the two transmission shafts 9 are connected through the coordinated transmission of the synchronous wheel and the synchronous belt. The two transmission shafts 9 synchronously drive the four transmission rods 10 to reciprocate longitudinally, which enhances the stability of the driving seat 2 during the longitudinal reciprocating motion, thereby ensuring the stability of the die-cutting mechanism during the die-cutting operation.

[0032] The frame 1 is rotatably provided with two guide wheels 13 located on both sides of the transmission rod 10 and in contact with the transmission rod 10. The two guide wheels 13 play a guiding role when the transmission rod 10 makes a reciprocating longitudinal motion, thereby enhancing the stability of the transmission rod 10 when driving the driving seat 2 by the reciprocating longitudinal motion, thereby ensuring the stability of the die-cutting mechanism during the die-cutting operation.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
