Detailed implementation manners
[0025] The following described embodiments are only a part of the embodiments of the present invention, and do not represent all embodiments consistent with the present invention. Now, in conjunction with the drawings, the exemplary embodiments are described as follows:
[0026] As Figures 1-5 shown, the pressing and cutting device for the processing of the packaging box of the present invention includes a bottom plate 1. A clamping component 2 is provided in the middle of the bottom plate 1. A fixing frame 3 is fixedly installed above the rear of the bottom plate 1. Fixing strips 4 are fixedly installed on the inner walls of the left and right sides of the fixing frame 3. Electric telescopic rods 5 are symmetrically and fixedly installed at the top of the fixing frame 3. The telescopic ends of the electric telescopic rods 5 are fixedly connected to a cross plate 6. A cutting knife 7 is fixedly connected to the rear of the cross plate 6. Guide grooves 8 are symmetrically formed on the left and right sides of the cutting knife 7. A pressing component 9 is installed below the cross plate 6.
[0027] On the basis of the above structure, the clamping component 2 includes a servo motor 21, a bidirectional lead screw 22 and a clamping plate 23. The servo motor 21 is fixedly installed on the left side wall of the bottom plate 1. The output end of the servo motor 21 is fixedly connected to the bidirectional lead screw 22. The bidirectional lead screw 22 is installed on the middle position of the bottom plate 1 through bearings. Clamping plates 23 are threadedly sleeved on the outer sides of the left and right ends of the bidirectional lead screw 22 where the threads are opposite.
[0028] In this embodiment, by using the servo motor 21 to control the rotation of the bidirectional lead screw 22, the two clamping plates 23 can be controlled to slide synchronously in opposite directions, facilitating the clamping and positioning of the cardboard and ensuring the stability of the cardboard state during the cutting process.
[0029] On the basis of the above structure, the guide groove 8 includes a vertical section and an inclined section at the bottom of the vertical section, and the vertical section and the inclined section are interconnected. The distance between the inclined sections at the bottoms of the left and right guide grooves 8 decreases in the vertically downward direction.
[0030] On the basis of the above structure, the pressing assembly 9 includes a pressure rod 91, a vertical shaft 92, a movable rod 94, a bent rod 95, and a through groove 96. Vertical shafts 92 are symmetrically fixed to the upper end of the pressure rod 91. Movable rods 94 are slidably connected to the interiors of the left and right ends of the pressure rod 91. Through grooves 96 are symmetrically formed in the upper end of the pressure rod 91. The bent rod 95 is in an "L" shape, and one end of the bent rod 95 passes through the through groove 96 and is fixedly connected to the upper end face of the movable rod 94.
[0031] On the basis of the above structure, the top end of the vertical shaft 92 passes through the cross plate 6 and is slidably connected to the cross plate 6. A spring 93 is sleeved on the outer side of the vertical shaft 92, and the two ends of the spring 93 are fixedly connected to the closer sides of the pressure rod 91 and the cross plate 6 respectively.
[0032] In this embodiment, when starting the electric telescopic rod 5 to control the synchronous downward movement of the cross plate 6, the cutting knife 7, and the pressing assembly 9, the pressure rod 91 can be used to press the cardboard before cutting the cardboard, facilitating ensuring the smoothness of the cardboard cut, avoiding situations such as burrs and nicks, having a higher cutting efficiency, and better product quality.
[0033] On the basis of the above structure, the bent rod 95 is slidably connected to the pressure rod 91 through the through groove 96, and the end of the bent rod 95 away from the movable rod 94 is guided and slides inside the guide groove 8.
[0034] On the basis of the above structure, serrated structures capable of engaging with each other are provided on the closer sides of the movable rod 94 and the fixed strip 4, and the cutting knife 7 and the pressure rod 91 are slidably attached to each other.
[0035] In this embodiment, when the cutting knife 7 moves downward relative to the pressure rod 91, the guide groove 8 can be used to push the bent rod 95 to drive the movable rod 94 to extend, so that the movable rod 94 engages with the fixed strip 4, facilitating the positioning of the pressure rod 91 and ensuring the stable pressing of the cardboard.
[0036] The working principle of the present utility model is as follows:
[0037] During use, first stack the cardboard to be cut and processed neatly and place it above the bottom plate 1, with the position of the cardboard to be cut directly below the cutting knife 7. Subsequently, the servo motor 21 can be started to control the rotation of the bidirectional lead screw 22, thereby enabling the control of the two clamping plates 23 to move synchronously in the direction of approaching each other, achieving the clamping and positioning of the cardboard and ensuring the stability of the cardboard state during the cutting process.
[0038] Subsequently, start the two electric telescopic rods 5 symmetrically arranged on the left and right at the top of the fixing frame 3, and control the cross plate 6 to drive the cutting knife 7 and the pressing component 9 to move downward synchronously. At this time, the pressing rod 91 first contacts the cardboard and remains stationary. When the electric telescopic rod 5 continues to extend, the cross plate 6 and the cutting knife 7 can be controlled to continue to move stably downward relative to the pressing rod 91 along the vertical axis 92. At this time, the spring 93 is gradually compressed, facilitating the pressing of the cardboard by the pressing rod 91. Moreover, when the cutting knife 7 moves downward, the bottom inclined section of the internal guide groove 8 thereof can be used to push the bent rod 95 to drive the movable rod 94 to extend out of the pressing rod 91. By the interlocking of the movable rod 94 and the fixed strip 4, the positioning of the pressing rod 91 is facilitated, so that during the process of the cutting knife 7 moving downward to cut the cardboard, the pressing rod 91 always presses the cardboard, facilitating the ensuring of the flatness of the cardboard cut and avoiding the occurrence of burrs, nicks and other situations, with higher cutting efficiency and better product quality. When one end of the bent rod 95 enters the vertical section of the guide groove 8, the movable rod 94 can be made stationary and stably interlocked with the fixed strip 4, and the cutting knife 7 can continue to move downward to complete the cutting of the cardboard.
[0039] The above is only a preferred specific embodiment of the present invention and is not intended to limit the protection scope of the present invention; all equivalent changes, modifications, substitutions and variations made by those skilled in the art in this technical field according to the concept of the present invention on the basis of the prior art through logical analysis, reasoning or limited experiments shall fall within the protection scope determined by the claims.
