Abstract
Description
Technical Field
[0001] This utility model relates to the field of slitting machine technology, specifically a slitting machine with a correction and early warning alarm mechanism. Background Technology
[0002] A slitting machine is a mechanical device that cuts wide-width paper, film, mica tape, and other materials into multiple narrow strips. It is widely used in industries such as papermaking, wire and cable manufacturing, and printing and packaging, and is characterized by high efficiency, precision, and strong adaptability. However, traditional slitting machines are mostly simple in structure and have limited functionality. In the transport and slitting of antibacterial films, the lack of a correction function often leads to film deviation during transport, resulting in slitting errors, increased product defect rates, and negatively impacting product appearance and subsequent use. This also hinders the smooth and orderly operation of production and business activities. To improve this situation, a slitting machine with a correction and early warning alarm mechanism is proposed.
[0003] For example, the slitting device with correction function disclosed in the authorization announcement number CN222348305U includes a slitting machine, a conveyor belt is provided below the slitting machine, a correction mechanism is provided on the side of the conveyor belt, and a pressing mechanism is provided above the conveyor belt. The correction mechanism includes a motor, and the output end of the motor is fixedly connected to a rotating shaft.
[0004] Although it achieves the function of periodically squeezing and limiting the transport position of the antibacterial film on the conveyor belt by setting the correction mechanism, it is beneficial to adjust the transport position of the antibacterial film and prevent it from shifting, which would cause deviation when the slitting machine performs slitting operations. This reduces the defect rate of the product, improves the production efficiency and quality of the equipment, reduces the workload of the operators, and facilitates the smooth and orderly operation of production and business activities.
[0005] However, the existing slitting machine does not solve the problems of inflexible adjustment of the film cutting position and linkage tensioning of the film during use, nor does it facilitate adaptation and limit warning for films of different widths or smoother film cutting operations, thus affecting the quality of film cutting. Utility Model Content
[0006] The purpose of this invention is to provide a slitting machine with a correction and early warning alarm mechanism to solve the problems mentioned in the background art, such as the slitting machine's inconvenience in flexibly adjusting the film's cutting position and linking and stretching the film, which is not conducive to adapting to films of different widths for limit warning and to performing a smoother film cutting operation, thus affecting the quality of film cutting.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a slitting machine with a correction and early warning alarm mechanism, comprising a support frame and a take-up roller. The top of the support frame is provided with a take-up roller. Two sets of integrated frames are provided on the side wall of the support frame, and a sliding rod is provided on the side wall of the support frame between the two sets of integrated frames. A right limiting roller is movably installed on the top of the support frame on one side of the integrated frame, and a left limiting roller is movably installed on the top of the support frame on the side of the right limiting roller. A bidirectional lead screw is provided inside each integrated frame, and the bidirectional lead screw is movably connected to the integrated frame. A stepper motor is provided on the side wall of each integrated frame, and the output end of the stepper motor is connected to the bidirectional lead screw. Two sets of threaded sleeves are fitted on the surface of each bidirectional lead screw, and the threaded sleeves are threadedly connected to the bidirectional lead screw. Sensors are provided on the surface of each threaded sleeve, and the two sets of sensors face each other and are located on the same center line.
[0008] Preferably, an electric push rod is movably installed inside the support frame, and a push arm is installed at the output end of the electric push rod.
[0009] Preferably, a linkage frame is provided at the end of the push arm away from the electric push rod, and a hinge shaft is provided at the end of the linkage frame near the push arm, and the linkage frame is movably connected to the push arm through the hinge shaft.
[0010] Preferably, a linkage shaft is provided on the side wall of the linkage frame, and the linkage frame is movably connected to the support frame through the linkage shaft.
[0011] Preferably, a tension roller is provided at the end of the linkage frame away from the electric push rod, and the tension roller is movably connected to the linkage frame.
[0012] Preferably, a sliding sleeve is slidably disposed on the surface of the slide rod, and a cutting blade is disposed at the top end of the sliding sleeve.
[0013] Preferably, the bottom end of the sliding sleeve is provided with a locking pin, and the locking pin extends through the sliding sleeve to the surface of the sliding rod, and the locking pin is threadedly connected to the sliding sleeve.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the slitting machine not only realizes the flexible adjustment of the film cutting position and the linkage of pulling and tightening the film, which facilitates the adaptation of films of different widths for limit warning and the smoother cutting operation of the film, but also improves the quality of film cutting.
[0015] The film is pulled from the upper surface of the tension roller, the lower surface of the left limit roller, the upper surface of the right limit roller, and between the two sets of integrated frames to the surface of the take-up roller and fixed on the take-up roller. The take-up roller then winds up the film. A cutting blade is mounted on the top of a sliding sleeve. The sliding sleeve moves along the surface of a slide rod. When the sliding sleeve reaches the cutting position, the locking pin is tightened to fix the sliding sleeve to the slide rod surface. During the film's movement, the cutting blade cuts the film. By adjusting the position of the sliding sleeve, different film cutting widths can be accommodated. Simultaneously, the distance between the two sets of sensors is adjusted according to the film width. The adjustment method is as follows: driven by a stepper motor... The bidirectional lead screw rotates, driving two sets of threaded sleeves to move towards each other. The threaded sleeves then move the sensor downwards, positioning it at the side of the film. When the object being measured enters the optical path and blocks the light, the receiver triggers a signal change due to the weakening or disappearance of the light intensity. This, in turn, changes the switch output state. If the film shifts and enters the range of the through-beam light source, an electrical signal is generated. This signal is transmitted to the controller to generate an alarm, alerting the operator that the film has shifted. This allows for flexible adjustment of the film's cutting position, facilitating adaptation and limit warning for films of different widths, and providing convenient alarm warnings for film shifting.
[0016] The push arm is moved by an electric push rod, and the push arm drives the linkage frame to rotate around the linkage shaft via a hinge shaft. The linkage frame drives the tension roller to rotate. Under the limiting action of the left limit roller, the tension roller pulls the film to tighten it. Cutting the film in a taut state is smoother than cutting it when it is loose, thereby improving the quality of film cutting. This achieves linkage pulling and tightening of the film, which facilitates smoother film cutting and improves the quality of film cutting. Attached Figure Description

[0026] Example 1
[0027] Please see Figures 1-5This utility model provides an embodiment of a slitting machine with a correction and early warning alarm mechanism, including a support frame 1 and a take-up roller 2. The top of the support frame 1 is provided with the take-up roller 2. Two sets of integrated frames 3 are provided on the side wall of the support frame 1, and a sliding rod 7 is provided on the side wall of the support frame 1 between the two sets of integrated frames 3. A right limiting roller 4 is movably installed on the top of the support frame 1 on one side of the integrated frame 3, and a left limiting roller 5 is movably installed on the top of the support frame 1 on the side of the right limiting roller 4. A bidirectional lead screw 13 is provided inside the integrated frame 3, and the bidirectional lead screw 13 is movably connected to the integrated frame 3. A stepper motor 16 is provided on the side wall of the integrated frame 3. The stepper motor 16 plays the role of power drive, and the output end of the stepper motor 16 is connected to the bidirectional lead screw 13. Two sets of threaded sleeves 14 are fitted on the surface of the bidirectional lead screw 13, and the threaded sleeves 14 are threadedly connected to the bidirectional lead screw 13. Sensors 15 are provided on the surface of the threaded sleeves 14, and the two sets of sensors 15 face each other and are on the same center line.
[0028] When film cutting is required, the film is pulled from the upper surface of tension roller 6, the lower surface of left limit roller 5, the upper surface of right limit roller 4, and between the two sets of integrated frames 3 to the surface of take-up roller 2 and fixed on take-up roller 2. Take-up roller 2 then winds up the film. Cutting blade 18 is installed at the top of sliding sleeve 17. Sliding sleeve 17 moves on the surface of slide rod 7. When sliding sleeve 17 moves to the cutting position, locking pin 19 is tightened to fix sliding sleeve 17 on the surface of slide rod 7. During the film movement, cutting blade 18 cuts the film. The position of sliding sleeve 17 can be adjusted to accommodate different... The film cutting width is determined, and the distance between the two sets of sensors 15 is adjusted according to the film width. The adjustment method is as follows: the stepper motor 16 is turned on, and the stepper motor 16 drives the bidirectional lead screw 13 to rotate. Under the threaded connection between the bidirectional lead screw 13 and the threaded sleeve 14, the bidirectional lead screw 13 drives the two sets of threaded sleeves 14 to move towards each other. The threaded sleeve 14 drives the sensor 15 to move downward, so that the sensor 15 moves to the side position of the film. The sensor 15 is a CHANKO-NPN-CPA through-beam photoelectric sensor. Its working principle is to continuously send a light beam to the receiver through a light emitter such as a laser or infrared light source. When the object being measured enters the light path and blocks the light, the receiver triggers a signal change due to the weakening or disappearance of the light intensity, which in turn controls the switch output state to change. If the film shifts and enters the range of the through-beam light source, an electrical signal will be generated. This electrical signal is transmitted to the controller to generate an alarm, so as to remind the operator that the film has shifted. This realizes flexible adjustment of the film cutting position, facilitates the adaptation of films of different widths, limit warning, and facilitates alarm warning for film shift.
[0029] An electric push rod 8 is movably installed inside the support frame 1. The electric push rod 8 serves as a power drive. A push arm 9 is installed at the output end of the electric push rod 8. A linkage frame 12 is provided at the end of the push arm 9 away from the electric push rod 8. A hinge shaft 11 is provided at the end of the linkage frame 12 close to the push arm 9. The linkage frame 12 is movably connected to the push arm 9 through the hinge shaft 11.
[0030] A linkage shaft 10 is provided on the side wall of the linkage frame 12, and the linkage frame 12 is movably connected to the support frame 1 through the linkage shaft 10. A tension roller 6 is provided at the end of the linkage frame 12 away from the electric push rod 8, and the tension roller 6 is movably connected to the linkage frame 12.
[0031] A sliding sleeve 17 is slidably provided on the surface of the sliding rod 7. A cutting blade 18 is provided at the top of the sliding sleeve 17, and a locking pin 19 is provided at the bottom of the sliding sleeve 17. The locking pin 19 extends through the sliding sleeve 17 to the surface of the sliding rod 7, and the locking pin 19 is threadedly connected to the sliding sleeve 17.
[0032] During the film slitting process, to ensure a smoother slitting, the electric push rod 8 can be activated, which drives the push arm 9 to move. The push arm 9, through the hinge shaft 11, drives the linkage frame 12 to rotate around the linkage shaft 10. The linkage frame 12 then drives the tension roller 6 to rotate. With the limiting action of the left limit roller 5, the tension roller 6 pulls the film to tighten it. Cutting the film under tension results in a smoother cut than cutting it loosely, thus improving the quality of film slitting. This linkage-driven tensioning of the film facilitates a smoother slitting operation and improves the quality of film slitting.
[0033] Work steps
[0034] When the film needs to be cut, the film is pulled from the upper surface of the tension roller 6, the lower surface of the left limit roller 5, the upper surface of the right limit roller 4, and between the two sets of integrated frames 3 to the surface of the take-up roller 2 and fixed on the take-up roller 2. The take-up roller 2 then takes up the film. The cutter 18 is installed at the top of the sliding sleeve 17. The sliding sleeve 17 is slid and moves on the surface of the slide rod 7. When the sliding sleeve 17 moves to the cutting position, the locking pin 19 is tightened to fix the sliding sleeve 17 on the surface of the slide rod 7. During the film movement, the cutter 18 cuts the film. By adjusting the position of the sliding sleeve 17, different film cutting widths can be adapted. At the same time, according to the width of the film, the distance between the two sets of sensors 15 is adjusted. The adjustment method is as follows: the stepper motor 16 drives the bidirectional lead screw 13 to rotate, the bidirectional lead screw 13 drives the two sets of threaded sleeves 14 to move towards each other, and the threaded sleeves 14 drive the sensors 15 downward. The sensor 15 is moved to the side of the film. When the object being measured enters the light path and blocks the light, the receiver triggers a signal change due to the weakening or disappearance of the light intensity, which in turn controls the switch output state to change. If the film deviates and enters the range of the through light source, an electrical signal will be generated. This electrical signal is transmitted to the controller to generate an alarm, so as to remind the operator that the film has been displaced. During the film cutting process, in order to ensure a smoother film cutting, the electric push rod 8 drives the push arm 9 to move. The push arm 9 drives the linkage frame 12 to rotate around the linkage shaft 10 through the hinge shaft 11. The linkage frame 12 drives the tension roller 6 to rotate. Under the limiting cooperation of the left limit roller 5, the tension roller 6 pulls the film to tighten it. Cutting the film in a taut state is smoother than cutting it when it is loose, thereby improving the quality of film cutting. The above is the complete usage of the slitting machine with the correction and early warning alarm mechanism.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
