Description

Technical Field

[0001] This utility model relates to the field of rewinding machine technology, and in particular to an automatic knife setting device for a rewinding machine. Background Technology

[0002] In modern manufacturing, rewinding machines are an important production equipment widely used in the raw material processing of industries such as textiles, paper, and plastic film. Their main function is to rewind long rolls of material into smaller rolls for subsequent use or packaging. However, the cutting tool system of rewinding machines generally requires manual adjustment.

[0003] Existing tape rewinding machines often result in uneven edges during the rewinding process due to varying tape widths, leading to poor rewinding performance, which fails to meet usage requirements and is inconvenient to use. The existing patent (publication number: CN215923908U) describes a tape rewinding machine. Through the cooperation of structures such as the first winding roller, the first motor, the threaded rod, the first threaded sleeve, and the second winding roller, it achieves the goal of ensuring the flatness of the edges on both sides of the tape, making it suitable for tapes of different widths. The rewinding effect is good, meeting the usage requirements and making it convenient to use.

[0004] Existing patents offer solutions to the above problems, but they have limitations such as the inability to automatically adjust the spacing between multiple dividing blades and the inability to adjust the cutting depth and position of the cutting blades.

[0005] To address this, an automatic knife-setting device for a rewinding machine is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an automatic blade alignment device for a rewinding machine, which can solve the problems of existing tape rewinding machines that cannot automatically adjust the spacing of multiple dividing blades and cannot adjust the cutting depth and cutting position of the cutting blades.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic blade setting device for a rewinding machine, comprising a frame, an installation strip provided in the middle of the frame, a plurality of cutting blades provided at the top of the installation strip, an adjustment blade setting mechanism provided on the side wall of the installation strip, and a moving drive mechanism provided between the installation strip and the frame; The adjusting tool setting mechanism includes a slide bar fixedly connected to the top of the mounting strip. Multiple sliders are movably arranged on the top of the slide bar. A mounting block is fixedly connected to the top of the slider. One end of the mounting block is fixedly connected to the cutting blade. A drive head is provided at the other end of the mounting block. A base is fixedly connected to the bottom of the mounting strip. A first electric push rod is fixedly connected to the middle of the base. An adjusting plate is fixedly connected to the output end of the first electric push rod. Multiple inclined grooves are formed on the side wall of the adjusting plate. The inclined grooves are movably connected to the drive head.

[0008] Preferably, the moving drive mechanism includes an adjustment frame disposed inside the frame, two second electric push rods are bolted to the inner wall of the adjustment frame, the output end of the second electric push rods is fixedly connected to the mounting strip, a top plate is fixedly connected to the top of the frame, a lifting screw is threadedly connected to the middle of the top plate, and the bottom of the lifting screw is movably connected to the adjustment frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application incorporates an adjustable blade setting mechanism. During this process, when the first electric push rod pushes the adjusting plate to move horizontally, the drive head slides along the inclined groove, driving the mounting block to move the cutting blade radially. By utilizing the cooperation between the inclined groove and the inclined surface of the drive head, the linear motion of the adjusting plate is converted into the radial displacement of the cutting blade, achieving precise adjustment of the spacing between multiple cutting blades and blade setting operations. By adjusting the blade setting mechanism, the position of the cutting blades can be precisely adjusted for blade setting operations, improving the production efficiency and cutting quality of the rewinding machine and ensuring the accuracy of the cutting effect.

[0016] 2. This application incorporates a moving drive mechanism, which employs a layered control mode of "first electric push rod lateral drive + lifting screw longitudinal adjustment". The second electric push rod enables lateral displacement of the mounting strip (and its cutting blade), while the lifting screw enables longitudinal height adjustment of the mounting strip, thereby adjusting the cutting depth and position of the cutting blade and adapting to the cutting of materials of different materials.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: An automatic blade setting device for a rewinding machine includes a frame 1, an mounting strip 2 in the middle of the frame 1, a plurality of cutting blades 3 on the top of the mounting strip 2, a blade setting adjustment mechanism 4 on the side wall of the mounting strip 2, and a moving drive mechanism 5 between the mounting strip 2 and the frame 1. The adjusting blade setting mechanism 4 includes a slide bar 41 fixedly connected to the top of the mounting strip 2. Multiple sliders 42 are movably arranged on the top of the slide bar 41. A mounting block 43 is fixedly connected to the top of the slider 42. One end of the mounting block 43 is fixedly connected to the cutting blade 3. A drive head 44 is provided at the other end of the mounting block 43. A base 45 is fixedly connected to the bottom of the mounting strip 2. A first electric push rod 46 is fixedly connected to the middle of the base 45. An adjusting plate 47 is fixedly connected to the output end of the first electric push rod 46. Multiple inclined grooves 48 are opened on the side wall of the adjusting plate 47. The inclined grooves 48 are movably connected to the drive head 44.

[0022] Specifically, such as Figure 3 As shown, the inclined grooves 48 located at both ends of the adjusting plate 47 are symmetrically arranged.

[0023] Specifically, such as Figure 3 As shown, guide rods 6 are fixedly connected to both ends of the base 45, and guide sleeves 7 are fixedly connected to both ends of the adjusting plate 47. The guide rods 6 and guide sleeves 7 are movably connected.

[0024] Specifically, such as Figure 4 As shown, a positioning screw 14 is provided at one end of the mounting block 43, and the bottom of the positioning screw 14 contacts the mounting strip 2.

[0025] In use, firstly, when the first electric push rod 46 pushes the adjusting plate 47 to move horizontally, the drive head 44 slides along the inclined groove 48, driving the mounting block 43 to move the cutting blade 3 radially. By utilizing the inclined groove 48 and the inclined surface of the drive head 44, the linear motion of the adjusting plate 47 is converted into the radial displacement of the cutting blade 3, achieving precise adjustment of the spacing between multiple cutting blades 3 and blade setting operation. During this process, the slider 42 slides on the top of the slide bar 41 to guide and limit the movement of the cutting blade 3. The adjusting plate 47 cooperates with the guide rod 6 through the guide sleeve 7 to eliminate the first electric... The push rod 46 is biased to ensure that the translation direction of the adjusting plate 47 is perpendicular to the mounting strip 2, thus avoiding blade adjustment deviation. The mounting block 43 contacts the mounting strip 2 through the positioning screw 14, providing initial preload before adjustment to prevent blade wobbling. By tightening the positioning screw 14, the mounting block 43 and the mounting strip 2 are rigidly fixed, ensuring the blade position is stable during cutting. In this way, by adjusting the blade setting mechanism 4, the position of the cutting blade 3 can be precisely adjusted, improving the production efficiency and cutting quality of the rewinding machine and ensuring the accuracy of the cutting effect.

[0026] Specifically, such as Figure 3 As shown, the moving drive mechanism 5 includes an adjustment frame 51 disposed inside the frame 1. Two second electric push rods 52 are bolted to the inner wall of the adjustment frame 51. The output end of the second electric push rod 52 is fixedly connected to the mounting strip 2. A top plate 53 is fixedly connected to the top of the frame 1. A lifting screw 54 is threadedly connected to the middle of the top plate 53. The bottom of the lifting screw 54 is movably connected to the adjustment frame 51.

[0027] Specifically, such as Figure 5 As shown, slide blocks 8 are fixedly connected to both ends of the mounting strip 2, support plates 9 are fixedly connected to the inner wall of the adjusting frame 51, and slide plates 10 are fixedly connected to the top of the support plates 9. The slide blocks 8 and slide plates 10 are movably connected.

[0028] Specifically, such as Figure 3 As shown, the top of the adjusting frame 51 is fixedly connected to two limiting rods 11, and the top of the top plate 53 is provided with a limiting cylinder 12, with the limiting rods 11 and the limiting cylinder 12 being movably connected.

[0029] Specifically, such as Figure 3 As shown, a locking screw 13 is threaded onto the side wall of the directional cylinder 12, and one end of the locking screw 13 contacts the directional rod 11.

[0030] The moving drive mechanism 5 adopts a layered control mode of "lateral drive by the first electric push rod 46 + longitudinal adjustment by the lifting screw 54". Lateral displacement of the mounting strip 2 (and its cutting blade 3) is achieved through the second electric push rod 52, and longitudinal height adjustment of the mounting strip 2 is achieved through the lifting screw 54, meeting the slitting requirements of raw materials of different specifications. Lateral movement is guided by the slide plate 10-slide seat 8, and longitudinal movement is guided by the limiting rod 11-limiting cylinder 12, ensuring the positioning accuracy and stability of the mounting strip 2 in multi-dimensional movement. When the lifting screw 54 is rotated, the adjusting frame 51 is positioned on the lifting screw... Under the action of 54, it moves longitudinally up and down, driving the mounting strip 2 to move synchronously. The limiting rod 11 at the top of the adjusting frame 51 is inserted into the limiting cylinder 12 of the top plate 53 to eliminate the rotational torque of the lifting screw 54, ensuring that the adjusting frame 51 moves only along the axial direction, avoiding lateral load causing the screw to jam or wear. After the longitudinal adjustment is completed, the locking screw 13 on the side wall of the limiting cylinder 12 is mechanically locked by tightening the limiting rod 11 to prevent vibration or external force from causing the adjusting frame 51 to loosen. In this way, the cutting depth and cutting position of the cutting blade 3 can be adjusted, which can adapt to the cutting of materials of different materials.

[0031] By adopting the above technical solution, the problems of existing tape rewinding machines being unable to automatically adjust the spacing of multiple dividing blades and being unable to adjust the cutting depth and cutting position of the cutting blade 3 have been solved.

[0032] Working principle: In use, the moving drive mechanism 5 first adopts a layered control mode of "first electric push rod 46 for lateral drive + lifting screw 54 for longitudinal adjustment". The second electric push rod 52 realizes the lateral displacement of the mounting strip 2 (and the cutting blade 3 on it) and the lifting screw 54 realizes the longitudinal height adjustment of the mounting strip 2 to meet the cutting requirements of raw materials of different specifications. When the first electric push rod 46 pushes the adjusting plate 47 to move horizontally, the drive head 44 slides along the inclined groove 48, and drives the mounting block 43 to move the cutting blade 3 radially. By utilizing the inclined groove 48 and the inclined surface of the drive head 44, the linear motion of the adjusting plate 47 is converted into the radial displacement of the cutting blade 3, so as to realize the precise adjustment of the spacing between multiple cutting blades 3 and the blade setting operation.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
