DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to 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 the embodiments. Based on the embodiments in 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.
[0022] See also Figure 1-4The utility model provides a technical solution: a length-adjustable paper box positioning and cutting device, comprising: a bracket 1, a conveyor belt 2 is arranged at the left and right ends of the upper surface of the bracket 1, a positioning plate 3 is arranged at the right end of the upper surface of the bracket 1, a cutting knife bracket 4 is arranged in the middle of the left and right ends of the bracket 1, a motor 5 is arranged at the upper end of the cutting knife bracket 4 at the left end, and a screw seat 6 is arranged at the upper end of the cutting knife bracket 4 at the right end, a screw rod 7 is connected between the motor 5 and the screw rod seat 6, a cutting knife seat 8 is rotatably connected in the middle of the screw rod 7, a cutting knife motor is arranged inside the cutting knife seat 8, a cutting knife 9 is connected to the lower end of the cutting knife seat 8, the lower end of the cutting knife 9 is lower than the height of the upper surface of the conveyor belt 2, and the cutting knife 9 A guide rod 10 is arranged between the two conveyor belts 2, between the two cutting knife brackets 4 and at the lower end of the motor 5 and the screw rod seat 6, and the guide rod 10 is inserted and connected with the cutting knife seat 8. Hydraulics 11 are arranged on the left and right surfaces of the bracket 1 and at the front and rear ends of the cutting knife bracket 4. A screw rod 12 is connected between the two hydraulic compressors 11 at the front end, and a screw rod 2 13 is connected between the two hydraulic compressors 11 at the rear end. Pressing conveyor belts 14 are connected to the left and right ends of the screw rods 12 and 13, and the height of the pressing conveyor belt 14 is lower than the guide rod 10. The length-adjustable carton positioning and cutting device has a pressing conveyor belt 14 to press the cardboard after the cardboard is sent in to prevent the cardboard from tilting during cutting.
[0023] like Figure 1-3 As shown, an embodiment of the utility model provides an implementation method, based on the above implementation method, a screw motor 21 is arranged on the upper end of the two hydraulic presses 11 at the left end, and a screw seat 22 is connected to the upper end of the two hydraulic presses 11 at the right end, the screw rod 1 12 and the screw rod 2 13 are both fixedly connected to one of the screw motors 21, the screw rod 1 12 and the screw rod 2 13 are both inserted and connected to one of the screw seats 22, the screw rod 12 is connected to the left end pressing transmission belt 14 by a thread, and the screw rod 2 13 is connected to the right end pressing transmission belt 14 by a thread.
[0024] From the analysis of the above structure, it can be known that the screw rod 12 is connected to the left end pressing transmission belt 14 through a threaded connection, and the screw rod 2 13 is connected to the right end pressing transmission belt 14 through a threaded connection. When the screw rod 12 rotates, it will drive the left end pressing transmission belt 14 to move axially along the screw rods 12 and the screw rods 2 13. When the screw rod 2 13 rotates, it will drive the right end pressing transmission belt 14 to move axially along the screw rods 12 and the screw rods 2 13, and move the two pressing transmission belts 14 to the left and right sides of the cutting knife seat 8. When cutting, due to the shortened distance, the tension in the middle will become greater, preventing the cardboard position from shifting and tilting. At the same time, when cutting a relatively narrow cardboard, the pressing transmission belt 14 can also be pressed on the upper surface of the cardboard.
[0025] like Figure 1-3As shown, an embodiment of the utility model provides an implementation method, based on the above implementation method, a pushing rod base 23 is provided at the rear end of the left surface of the bracket 1, and two pushing rods 24 are provided on the upper surface of the pushing rod base 23. The right end of the pushing rod 24 is connected to a guide plate 25, and the rear end of the guide plate 25 is arc-shaped, and the bottom of the guide plate 25 is close to the upper surface of the conveyor belt 2 and the front end is close to the rear end of the pressing conveyor belt 14.
[0026] From the analysis of the above structure, it can be known that after measuring the width of the cardboard, the push rod 24 is started, and the flat position of the guide plate 25 is pushed to a position slightly wider than the cardboard width from the positioning plate 3. When processing, it is only necessary to place the cardboard on the upper surface of the conveyor belt 2. The rear end of the guide plate 25 will automatically straighten the position of the cardboard. When it reaches the right end of the guide plate 25, it will be directly pressed by the conveyor belt 14 for transmission to prevent subsequent position deviation.
[0027] like Figure 1 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, a scale 26 is arranged between the guide rod 10 and the screw rod 7. The left and right ends of the scale 26 pass through the cutting knife seat 8 and are connected to the cutting knife bracket 4.
[0028] From the analysis of the above structure, it can be known that when adjusting the position of the cutting blade holder 8, the position marked on the scale 26 can be referred to.
[0029] like Figure 1 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the size of the scale 26 is offset to the right by half the width of the cutting tool seat 8.
[0030] Analysis of the above structure shows that since the cutting knife 9 is in the middle of the lower end of the cutting knife seat 8, the size on the scale 26 will differ from the cutting size by half the distance of the cutting knife seat 8, so it can be accurately found by shifting to the right by half the distance of the cutting knife seat 8.
[0031] like Figure 1-4 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the left end of the cutting knife 9 is connected to the cutting knife seat 8 through a nut.
[0032] From the analysis of the above structure, it can be known that if the cutting blade 9 is worn out or needs to be replaced, it can be replaced by simply unscrewing the nut.
[0033] When in use, first determine the required cutting length and thickness of the cardboard, start the motor 5 to drive the screw 7 to rotate, adjust the cutting knife seat 8 to the required position along the guide rod 10, then move the pressing conveyor belt 14 to both ends of the cutting knife seat 8, adjust the hydraulic press 11, adjust the pressing conveyor belt 14 to a suitable height, then start the pushing rod 24, push the guide plate 25 to the required position, place the cardboard on the upper surface of the conveyor belt 2, and then the guide plate 25 will straighten the position of the cardboard. After reaching the right end of the guide plate 25, it will be transmitted between the conveyor belt 2 and the pressing conveyor belt 14, and then cut by the cutting knife 9.
[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
