[0002] A cut-to-length machine is a machine used to cut materials. It can cut materials into the same length according to the set length. Cut-to-length machines are usually used to cut materials such as paper, plastic film, and metal sheets, and are widely used in packaging, printing, manufacturing and other industries.

[0003] A fixed-length cutting machine is disclosed in the utility model patent with the patent authorization announcement number CN205553001U, including a chassis, a guide rail is laid on the left end of the top of the chassis, a slide is installed on the guide rail, and the slide is slidably connected to the guide rail; a cutting tool is installed on the slide, and a semicircular groove is provided on the cutting tool, and the product is located in the groove; a cutting blade is provided on the right side of the slide, and the cutting blade is fixedly installed on the chassis. The utility model has a simple structure and a reasonable design, does not require marking, adopts mechanical automatic cutting, eliminates the marking process and personnel, ensures the flatness and verticality of the product port cutting and the safety of operation, and greatly improves production efficiency and saves labor costs.

[0004] However, the existing fixed-length cutting machines also have certain shortcomings. When the existing fixed-length cutting machines are cutting materials, although they mostly use electric drive to adjust the position of the cutting machine body, due to the influence of external factors such as inertia, it is easy to cause unnecessary movement of the moving block, which in turn makes the cutting machine body move inaccurately. Summary of the invention

[0005] The utility model aims to provide a fixed-length cutting machine, which solves the problem that when the existing fixed-length cutting machines are used to cut materials, although they mostly adopt electric drive to adjust the position of the cutting machine body, due to the influence of external factors such as inertia, the moving block is easily moved redundantly, thereby making the cutting machine body move inaccurately.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a fixed-length cutting machine, including a support frame, a support platform is arranged at the upper end of the support frame, a fixing plate 1 is installed by threading at the upper end of the support frame and located on the left side of the support platform, and a fixing plate 2 is installed by bolts at the upper end of the support frame and located on the right side of the support platform, a guide column is fixedly connected between the fixing plate 2 and the fixing plate 1, a moving block is slidably sleeved on the outer side of the guide column, a cutting machine body is arranged on the moving block, a motor is fixedly installed at the right end of the fixing plate 2, the output shaft of the motor is rotatably connected to the fixing plate 2, the output shaft of the motor is fixedly connected to a threaded rod, an anti-deflection mechanism is arranged on the threaded rod, and a positioning mechanism is jointly arranged on the output shaft of the motor and the fixing plate 2.

[0007] The principle of the utility model is: starting the motor drives the output shaft to rotate, so as to drive the threaded rod to rotate. Under the relationship of the threaded connection, the moving block can be driven to move. Under the action of the guide column, the moving block can be kept in a stable movement, thereby driving the cutting machine body to move, and adjusting the position of the cutting machine body to facilitate the subsequent fixed-length cutting. In this process, the inner wall of the positioning hole squeezes the positioning rod to push the guide plate to move, and the second spring is deformed, so that the positioning rod is finally separated from the positioning hole. Under the action of the force, the positioning rod slides along the surface of the output shaft of the motor. When the positioning rod slides into the next positioning hole, the second spring restores its deformation to push the positioning rod to insert into the positioning hole, limit the output shaft of the motor, and then limit the position of the moving block, and finally the position of the cutting machine body is finely controlled.

[0008] When the motor drives the output shaft to drive the threaded rod to rotate, it can drive the rotating disk to rotate, so that the anti-deflection rod slides along the inner wall of the limiting ring groove, limits the rotation of the rotating disk, and then limits the rotation of the threaded rod, to avoid the steering shake caused by the centrifugal force of the excessively long threaded rod. Under the deformation action of spring 1, the anti-deflection rod can be pulled to always contact the inner wall of the limiting ring groove to ensure the limiting effect of the anti-deflection rod.

[0009] The beneficial effect of the utility model is that the scheme can perform fixed-length cutting on materials through the coordinated use of structures such as a motor, a threaded rod, and a cutting machine body. Under the action of the positioning hole, the positioning rod, the spring and other structures, the output shaft of the motor can be limited, and then the position of the moving block can be regulated, and finally the position of the cutting machine body can be refined. Through the setting of the anti-deflection rod, the limiting ring groove, the spring and other structures, the rotation of the rotating disk can be limited, and then the threaded rod can be limited, so as to avoid the problem of steering jitter caused by an excessively long threaded rod, thereby reducing the rotational centrifugal force of the threaded rod and ensuring the normal movement of the moving block.

[0010] Furthermore, the anti-deflection mechanism includes a rotating disk, and two evenly distributed rotating disks are fixedly sleeved on the outer side of the threaded rod, and a limiting ring groove is provided on the surface of each rotating disk, and the end faces of the fixed plate 1 and the fixed plate 2 close to the support platform are fixedly connected to the mounting plate, and the mounting plate is slidably connected with an anti-deflection rod inside the mounting plate, and the anti-deflection rod is slidably connected to the limiting ring groove, and a spring 1 is arranged on the outer side of the anti-deflection rod. When the motor drives the output shaft to drive the threaded rod to rotate, the rotating disk can be driven to rotate, so that the anti-deflection rod slides along the inner wall of the limiting ring groove, and the rotating disk is rotationally limited, and then the threaded rod is rotationally limited, so as to avoid the problem of steering jitter caused by the centrifugal force of rotation of the excessively long threaded rod, and under the deformation action of the spring 1, the anti-deflection rod can be pulled to always contact with the inner wall of the limiting ring groove to ensure the limiting effect of the anti-deflection rod.

[0011] Furthermore, one end of the spring one is welded to the mounting plate, and the other end of the spring one is welded to the end plate of the anti-deflection rod. Through the setting of the spring one, the anti-deflection rod can be connected for use.

[0012] Furthermore, the positioning mechanism includes a positioning hole, a positioning hole is provided on the surface of the output shaft of the motor, a guide plate is slidably connected inside the second fixing plate, a positioning rod is fixedly connected to the upper end of the guide plate, the positioning rod is slidably connected to the second fixing plate, the positioning rod is slidably connected to the positioning hole, a second spring is provided on the outer side of the guide plate, and the output shaft is driven by the motor to rotate to drive the threaded rod to rotate. During this process, the inner wall of the positioning hole squeezes the positioning rod to push the guide plate to move, and the second spring is deformed, so that the positioning rod finally disengages from the positioning hole. Under the action of force, the positioning rod slides along the surface of the output shaft of the motor. When the positioning rod slides into the next positioning hole, the second spring restores its deformation to push the positioning rod to insert into the positioning hole, thereby limiting the output shaft of the motor, and then limiting the position of the moving block, and finally the position of the cutting machine body is finely controlled.

[0013] Furthermore, there are a plurality of positioning holes, which are arranged in a circular array on the output shaft of the motor. The positioning holes are arranged to facilitate the use of the positioning rod for clamping.

[0014] Furthermore, one end of the second spring is welded to the second fixing plate, and the other end of the second spring is welded to the horizontal portion of the positioning rod. By providing the second spring, the positioning rod can be tightened.

[0015] Furthermore, the threaded rod is rotatably connected to the fixed plate, and the threaded rod is connected to the moving block via threads. Through the threaded connection, when the threaded rod rotates, the moving block can be driven to move. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, an anti-deflection mechanism 10 is provided on the threaded rod 9, and the anti-deflection mechanism 10 includes a rotating disk 101. Two evenly distributed rotating disks 101 are fixedly sleeved on the outer side of the threaded rod 9. A limiting ring groove 102 is provided on the surface of each rotating disk 101. The end faces of the fixed plate 13 and the fixed plate 24 close to the support platform 2 are fixedly connected with a mounting plate 103. The inside of the mounting plate 103 is slidably connected with an anti-deflection rod 104. The anti-deflection rod 104 is slidably connected to the limiting ring groove 102. A spring 105 is provided on the outer side of the anti-deflection rod 104. One end of the spring 105 is welded to the mounting plate 103, and the other end of the spring 105 is welded to the anti-deflection rod 104. The end plate of the deflection rod 104 is welded, and the anti-deflection rod 104 can be connected and used through the setting of a spring 105. When the motor 8 drives the output shaft to drive the threaded rod 9 to rotate, the rotating disk 101 can be driven to rotate, so that the anti-deflection rod 104 slides along the inner wall of the limiting ring groove 102, and the rotating disk 101 is rotationally limited, and then the threaded rod 9 is rotationally limited to avoid the steering jitter problem of the excessively long threaded rod 9 due to the rotational centrifugal force. Under the deformation action of the spring 105, the anti-deflection rod 104 can be pulled to always contact the inner wall of the limiting ring groove 102 to ensure the limiting effect of the anti-deflection rod 104.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, a positioning mechanism 11 is commonly provided on the output shaft of the motor 8 and the fixed plate 24, and the positioning mechanism 11 includes a positioning hole 111. The surface of the output shaft of the motor 8 is provided with a positioning hole 111, and a plurality of positioning holes 111 are provided. The plurality of positioning holes 111 are arranged in a circular array on the output shaft of the motor 8. The setting of the positioning holes 111 facilitates the use of a positioning rod 113 for clamping. A guide plate 112 is slidably connected inside the fixed plate 24, and a positioning rod 113 is fixedly connected to the upper end of the guide plate 112. The positioning rod 113 is slidably connected to the fixed plate 24, and the positioning rod 113 is slidably connected to the positioning hole 111.

[0026] The specific implementation process of the utility model is as follows: start the motor 8 to drive the output shaft to rotate, so as to drive the threaded rod 9 to rotate. Under the relationship of the threaded connection, the moving block 6 can be driven to move. Under the action of the guide column 5, the moving block 6 can be made to be in a stable movement, thereby driving the cutting machine body 7 to move, and adjusting the position of the cutting machine body 7 to facilitate the subsequent fixed-length cutting. In this process, the inner wall of the positioning hole 111 squeezes the positioning rod 113 to push the guide plate 112 to move, and the spring 114 is deformed, and finally the positioning rod 113 is separated from the positioning hole 111. Under the action of the force, the positioning rod 113 slides along the surface of the output shaft of the motor 8. When the positioning rod 113 slides into the next positioning hole 111, the spring 114 recovers its deformation to push the positioning rod 113 to insert into the positioning hole 111, limit the output shaft of the motor 8, and then limit the position of the moving block 6, and finally the position of the cutting machine body 7 is finely controlled.

[0027] When the motor 8 drives the output shaft to drive the threaded rod 9 to rotate, it can drive the rotating disk 101 to rotate, so that the anti-deflection rod 104 slides along the inner wall of the limiting ring groove 102, and the rotating disk 101 is rotationally limited, and then the threaded rod 9 is rotationally limited to avoid the steering shake problem caused by the centrifugal force of the excessively long threaded rod 9. Under the deformation action of the spring 105, the anti-deflection rod 104 can be pulled to always contact the inner wall of the limiting ring groove 102 to ensure the limiting effect of the anti-deflection rod 104.

[0028] This solution can cut materials to a fixed length through the coordinated use of structures such as the motor 8, the threaded rod 9, and the cutting machine body 7. Under the action of structures such as the positioning hole 111, the positioning rod 113, and the spring 114, the output shaft of the motor 8 can be limited, and then the position of the moving block 6 can be regulated, and finally the position of the cutting machine body 7 can be refined. Through the setting of structures such as the anti-deflection rod 104, the limiting ring groove 102, and the spring 105, the rotation of the rotating disk 101 can be limited, and then the threaded rod 9 can be limited, so as to avoid the problem of steering jitter caused by the excessively long threaded rod 9, thereby reducing the rotational centrifugal force of the threaded rod 9 and ensuring the normal movement of the moving block 6.
