[0002] Currently, the upper waste removal template of the die-cutting machine is simply inserted into the waste removal frame and locked. The position of the upper waste removal template cannot be adjusted. Although this method can achieve the installation of the upper waste removal template, if there is a processing deviation between the upper and lower waste removal templates, resulting in a mismatch between the upper and lower waste removal templates, or if the waste removal blade of the upper waste removal template becomes slightly crooked due to long-term use, problems such as the waste removal blade scratching the cardboard or uneven waste removal occur during cardboard waste removal. This requires workers to spend a lot of time adjusting the machine, thus reducing production efficiency and increasing production costs. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0025] like Figures 1 to 6 As shown in the figure, this embodiment discloses a waste removal frame for a die-cutting machine, including a frame 1, a first gripper 2, a second gripper 3, a gripper driving mechanism (not shown in the figure), and a central positioning mechanism 4 for positioning the upper template 5 for waste removal. The gripper driving mechanism is disposed on the frame 1, and the second gripper 3 is disposed on the gripper driving mechanism. The gripper driving mechanism is used to drive the second gripper 3 to move laterally and reciprocally relative to the first gripper 2. The frame 1 is provided with a first fine-tuning mechanism 6 and a second fine-tuning mechanism 7. The first gripper 2 is disposed on the first fine-tuning mechanism 6, and the central positioning mechanism 4 is disposed on the second fine-tuning mechanism 7. The first fine-tuning mechanism 6 is used to drive the first gripper 2 to move laterally and reciprocally so that the first gripper 2 and the second gripper 3 cooperate to adjust the lateral position of the upper template 5 for waste removal. The second fine-tuning mechanism 7 is used to drive the central positioning mechanism 4 to move longitudinally and reciprocally so as to adjust the longitudinal position of the upper template 5 for waste removal.

[0026] In this embodiment, the waste removal frame of the die-cutting machine can adjust the horizontal position of the waste removal upper template 5 by driving the first gripper 2 to reciprocate linearly through the first fine-tuning mechanism 6, and adjusting the vertical position of the waste removal upper template 5 by cooperating with the second gripper 3. The second fine-tuning mechanism 7 can adjust the vertical position of the waste removal upper template 5 by driving the center positioning mechanism 4 to reciprocate linearly through the second fine-tuning mechanism 7. In this way, the position adjustment of the waste removal upper template 5 is realized, solving the problem of the non-adjustable position of the waste removal upper template 5, improving production efficiency and saving costs.

[0027] In this embodiment, the first fine-tuning mechanism 6 includes a first lead screw 61, a gripper seat 62, a transmission mechanism, and a first rotary drive 63. A mounting base 11 and a linear guide structure are provided on the frame 1. One end of the first lead screw 61 is rotatably mounted on the frame 1, and the other end is rotatably mounted on the mounting base 11. The gripper seat 62 is threadedly connected to the first lead screw 61. The first rotary drive 63 is rotatably mounted on the frame 1 and is connected to the first lead screw 61 via the transmission mechanism. The first rotary drive 63 drives the first lead screw 61 to rotate, and the first lead screw 61 drives the gripper seat 62 to reciprocate laterally in a linear motion, thereby driving the first gripper 2 to reciprocate laterally in a linear motion. The linear guide structure provides linear guidance to the gripper seat 62. The first lead screw 61 and the gripper seat 62 constitute a lead screw and nut mechanism. The lead screw and nut mechanism is a classic transmission device that converts rotary motion into linear motion. Its core advantages are high precision, high rigidity, self-locking, and reliability. Using a lead screw and nut mechanism for transmission improves the position adjustment accuracy and reliability of the first gripper 2.

[0028] The transmission mechanism in this embodiment adopts a gear transmission mechanism, including a rotating shaft 64 rotatably mounted on the mounting base 11, a driving gear 65 mounted on the rotating shaft 64, a driven gear 66 mounted on the first lead screw 61 and meshing with the driving gear 65, and a universal joint connecting the rotating shaft 64 and the first rotary drive member 63. The driving gear 65 and the driven gear 66 are helical gears. The gear transmission mechanism drives the lead screw and nut mechanism, ensuring both transmission efficiency and accuracy.

[0029] The linear guide structure in this embodiment includes a linear guide groove 121 and a guide shaft 67. A support plate 12 is provided on the frame 1. Both the mounting base 11 and the linear guide groove 121 are provided on the support plate 12. One end of the guide shaft 67 is provided on the frame 1, and the other end is provided on the mounting base 11. The gripper seat 62 is slidably disposed in the linear guide groove 121 and slidably disposed on the guide shaft 67. By providing a linear guide structure, the linearity of the movement of the first gripper 2 is improved.

[0030] Specifically, the frame 1 is formed by connecting two transverse connecting plates 13 and two longitudinal connecting plates 14. The support plate 12 is set on one of the longitudinal connecting plates 14. The first lead screw 61 and the rotating shaft 64 are arranged in parallel, with one end of the first lead screw 61 and the rotating shaft 64 set on the longitudinal connecting plate 14 and the other end of the first lead screw 61 and the rotating shaft 64 set on the mounting base 11. The first rotary drive member 63 is rotatably set on one of the transverse connecting plates 13.

[0031] In this embodiment, the frame 1 is provided with two first fine-tuning mechanisms 6. The two first fine-tuning mechanisms 6 cooperate with each other to adjust the position of the first gripper 2. The structures of the two first fine-tuning mechanisms 6 are basically the same, except that one of the first fine-tuning mechanisms 6 connects the connecting shaft 632 and the rotating shaft 64 through the first universal joint 69, and the other first fine-tuning mechanism 6 connects the connecting shaft 632 and the rotating shaft 64 through the second universal joint 610. The second universal joint 610 is longer than the first universal joint 69.

[0032] In this embodiment, the second fine-tuning mechanism 7 includes a second lead screw 71, a connecting block 72, a sliding plate 73, a first elastic element 74, and a second rotary drive element 75.

The second lead screw 71 and the connecting block 72 together constitute a lead screw and nut mechanism, which improves the position adjustment accuracy and reliability of the center positioning mechanism 4.

[0033] Specifically, at least two guide posts 16 are provided on the longitudinal connecting plate 14 of the frame 1, and the slide plate 73 is provided with waist holes that cooperate with the guide posts 16. The slide plate 73 is slidably mounted on the guide posts 16 through the waist holes. The axial limiting seat 15 is provided on the longitudinal connecting plate 14 and has two mounting arms. The longitudinal connecting plate 14 is also provided with a support seat 17. The second lead screw 71 is rotatably mounted on the support seat 17 and the two mounting arms of the axial limiting seat 15, and a limiting retaining ring 76 is sleeved on the second lead screw 71. The limiting retaining ring 76 is located between the two mounting arms. The second rotary drive member 75 is rotatably mounted on the transverse connecting plate 13.

[0034] In this embodiment, the center positioning mechanism 4 includes a locking block 41 and a locking claw 42. The locking block 41 is fixed on the slide plate 73, and one end of the locking claw 42 is hinged to the slide plate 73. The other end of the locking claw 42 is used to cooperate with the locking block 41 to lock the center positioning block 51 of the waste removal upper template 5. In this embodiment, the locking block 41 is located inside the locking claw 42, and the locking claw 42 is provided with a locking claw limiting protrusion 421 that cooperates with the locking block 41.

[0035] To facilitate the driving of the chuck 42, this embodiment provides a chuck pushing mechanism on the frame 1 for driving the chuck 42 to rotate. The chuck pushing mechanism includes a push rod 43 and a second elastic member 44. The push rod 43 is slidably disposed on the frame 1 and is hinged to the chuck 42. A limiting member 45 is provided on the push rod 43, and the second elastic member 44 is sleeved on the push rod 43 and located between the limiting member 45 and the frame 1.

[0036] Specifically, one end of the push rod 43 passes through the transverse connecting plate 13 and the support seat 17 in sequence and is hinged to the claw 42. The support seat 17 is located between the claw 42 and the limiting member 45, and the second elastic member 44 is located between the limiting member 45 and the support seat 17.

[0037] In this embodiment, both the first rotary drive component 63 and the second rotary drive component 75 include a handwheel 631 and a connecting shaft 632 coaxially arranged with the handwheel 631. The connecting shaft 632 is rotatably mounted on the transverse connecting plate 13 of the frame 1 and is used to connect to the universal joint or the second lead screw 71 of the transmission mechanism. An elastic self-locking structure is provided between the transverse connecting plate 13 of the frame 1 and the connecting shaft 632. By providing the elastic self-locking structure, the self-locking of the connecting shaft 632 is achieved, ensuring the convenience and reliability of position adjustment.

[0038] Specifically, the elastic self-locking structure includes a spring pin 68 disposed on the transverse connecting plate 13 of the frame 1 and a plurality of positioning grooves 633 disposed on the connecting shaft 632. All positioning grooves 633 are arranged in a circular array with the axis of the connecting shaft 632 as the central axis. When self-locking, the spring pin 68 is engaged in the corresponding positioning groove 633.

[0039] In order to ensure that the spring pin 68 can slide smoothly into or out of the positioning groove 633, this embodiment preferably uses a hemispherical groove for the positioning groove 633.

[0040] In this embodiment, both the first elastic element 74 and the second elastic element 44 are springs. Of course, they can also be elastic rubber bodies. The choice depends on the actual needs, and this embodiment does not limit this.

[0041] For ease of adjustment, both the first fine-tuning mechanism 6 and the second fine-tuning mechanism 7 in this embodiment are equipped with position displays 8. The position displays 8 are mounted on the transverse connecting plate 13 and sleeved on the connecting shaft 632. The position displays 8 are existing technology and are used to display the adjustment distance; their specific structure will not be described in detail here.

[0042] In use, the waste removal upper template 5 is centered by the central positioning mechanism 4. The first rotary drive 63 is rotated, which drives the first gripper 2 to move laterally in a reciprocating linear motion, so that the first gripper 2 and the second gripper 3 cooperate to adjust the lateral position of the waste removal upper template 5. The second rotary drive 75 is rotated, which drives the central positioning mechanism 4 to move longitudinally in a reciprocating linear motion to adjust the longitudinal position of the waste removal upper template 5 until the usage requirements are met. Then, the first gripper 2 and the second gripper 3 clamp the waste removal upper template 5.

[0043] The above describes a preferred embodiment of the waste removal frame for the die-cutting machine of this utility model. There are other embodiments, which will not be elaborated here. In summary, the waste removal frame for the die-cutting machine of this utility model solves the problem of the non-adjustable position of the upper waste removal template 5, improves production efficiency, and saves costs.

[0044] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
