Description

Technical Field

[0001] The utility model belongs to the technical field of film production equipment, and in particular relates to an automatic removal mechanism for roller-wrapped materials. Background Art

[0002] There are many methods for producing film products, such as stretching method, casting method, etc. However, no matter which production method is used, both sides of the film strip are not flat, and both sides of the film strip need to be cut and trimmed before winding. It can be seen that two waste strips will be generated after the existing film strip is cut. In the current film strip winding process, a roller is set above the front end of the winding roller to support the film strip forward, and the waste strips on both sides will be separated from the film strip under the action of gravity, thereby preventing the waste strips from being rolled into the winding roller.

[0003] However, in actual use, it is found that although the waste tape will not be rolled into the take-up roller due to the existence of the roller, the waste tape will be wrapped around the roller due to adhesion with the film tape or electrostatic adsorption, which will affect the normal operation of the roller. Once this happens, the machine needs to be stopped to manually remove the waste tape, which increases the workload and reduces the working efficiency of the equipment. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a mechanism for automatically removing material wrapped around rollers, which is used to solve the technical problem in the prior art that waste material produced after the film tape is cut will be wrapped around the rollers, causing downtime for troubleshooting, which not only increases the workload but also reduces the working efficiency of the equipment.

[0005] The utility model solves the above technical problems with the following technical solutions: a roller entanglement automatic removal mechanism, comprising:

[0006] A frame, wherein a support roller and a winding roller are provided on the frame, and the support roller is above the front end of the winding roller;

[0007] An automatic cutting component, the automatic cutting component is arranged below the roller, a cutter is arranged inside the automatic cutting component, and the cutter is tangent to the lower edge of the roller;

[0008] Two automatic absorbing components, the two automatic absorbing components are used to absorb the waste materials on both sides of the roller respectively;

[0009] At least two metal sensors are provided, and the two metal sensors face two sides of the roller.

[0010] The utility model utilizes two metal sensors to detect the roller. Once the roller is entangled with the waste belt, the metal sensor can find the difference between the waste belt and the roller, thereby starting the automatic cutting component to cut off the waste belt on the roller with a cutter, and then the automatic absorption component absorbs the cut waste belt. The above mechanism can automatically detect whether the roller is entangled with the waste belt, and then determine whether the cutting and absorption work is needed according to the detection result. It has a high degree of automation and can timely and effectively deal with the problem of the waste belt winding around the roller without stopping the machine for manual processing, which will no longer affect the working efficiency of the equipment.

[0011] Further: the automatic cutting component comprises:

[0012] Linear drives;

[0013] A cutter is arranged on the top surface of the slide seat of the linear drive.

[0014] The beneficial effect of adopting this step is that the slide can perform linear reciprocating motion on the linear drive, driving the cutter to cut the waste belt.

[0015] Furthermore: the two automatic absorption components are respectively fixed on the inner walls on both sides of the frame, or the two automatic absorption components are respectively fixed on both sides of the automatic cutting component.

[0016] The beneficial effect of adopting this step is that the automatic absorption component can be installed at a position selected according to the use requirements.

[0017] Further: the automatic absorption component includes:

[0018] Suction nozzle;

[0019] An air suction pump and an air suction pipeline, one end of the air suction pipeline is connected to the suction nozzle, and the other end is connected to the air suction pump;

[0020] The suction pump and / or the suction pipeline are provided with a filter.

[0021] The beneficial effect of adopting this step is: using the suction pump to create negative pressure and provide suction to suck up the waste belt.

[0022] Furthermore: waste suction pipes are provided on both inner walls of the frame, and the pipe openings of the two waste suction pipes are respectively directed toward the two sides of the top edge of the roller;

[0023] The waste suction pipeline is connected to the air suction pipeline.

[0024] The beneficial effect of adopting this step is: the waste belt is sucked by the waste suction pipe, thereby reducing the probability of the waste belt being wound around the roller.

[0025] Furthermore: the cutting knife is a single-edged sharp knife, a double-edged sharp knife or a rotatable round knife.

[0026] The beneficial effect of adopting this step: different forms of cutters have different cutting efficiencies.

[0027] The beneficial effects of the utility model are:

[0028] 1. The present application uses a metal sensor to detect whether the roller is wrapped with a waste belt. When it is detected that the roller is wrapped with a waste belt, the automatic cutting component and the automatic absorbing component will cut off and absorb the waste belt on the roller, thereby realizing the function of automatically removing the waste on the roller without stopping the machine for troubleshooting and reducing the working efficiency of the equipment;

[0029] 2. In the present application, the cut waste tape will be absorbed by the automatic absorption component at the same time, thereby preventing the cut waste tape from falling around the equipment, which not only protects the on-site environment but also achieves the purpose of waste recycling.

[0042] Example

[0043] like Figure 1 and Figure 2 As shown, the utility model provides a roller entanglement automatic removal mechanism, comprising:

[0044] A frame 1, wherein a support roller 2 and a winding roller 3 are provided on the frame 1, wherein the support roller 2 is above the front end of the winding roller 3, wherein the frame 1 is composed of two side plates and a plurality of cross beams 11 connecting the two side plates, and the spacing between the cross beams 11 allows the film roll on the winding roller 3 to be moved out of the frame 1;

[0045] An automatic cutting component 6, the automatic cutting component 6 is arranged below the roller 2, and a cutter is arranged inside the automatic cutting component 6, the cutter is tangent to the lower edge of the roller 2, and when the cutter moves back and forth below the roller 2, the waste belt wound on the roller 2 can be cut off;

[0046] Two automatic absorbing components 8, the two automatic absorbing components 8 are used to absorb the waste materials on both sides of the roller 2 respectively;

[0047] At least two metal sensors 7 are provided, and the two metal sensors 7 face the two sides of the roller 2. The metal sensors 7 can be of many types, such as inductive sensors, ultrasonic sensors or photoelectric sensors, etc. The characteristics of these sensors are as follows:

[0048] Inductive sensors are a common type of metal detection sensor. By measuring the effect of metal objects on the magnetic field, inductive sensors can distinguish between metal and non-metal materials. When a metal object approaches the inductive sensor, the inductance value of the sensor will change due to the influence of the magnetic field. The size and frequency of the change can be used to determine the distance from the metal object to the sensor and the type of metal.

[0049] Ultrasonic sensors measure the position and distance of objects by emitting high-frequency sound waves to the object and receiving the sound waves that bounce back. Specifically, after the ultrasonic sensor emits sound waves, the sound waves will reflect or pass through the surface of plastic and metal. Plastic and metal reflect sound waves differently, so the sensor can determine whether the object is metal or plastic by analyzing the signal returned by the sound wave.

[0050] The advantages of ultrasonic sensors are that they are suitable for non-metallic materials and have high reliability. However, ultrasonic sensors are expensive and have certain requirements for material thickness, surface shape, etc.

[0051] Photoelectric sensors are sensors based on optical principles that can be used to detect object shape, color, distance and other information. Photoelectric sensors are suitable for the detection of non-metallic materials and can detect the color and shape of objects. The detection principle of photoelectric sensors is to emit a beam of light, and when the object blocks the light, the sensor can obtain a signal. By analyzing the intensity and frequency of the signal, it can be determined whether the object is metal or plastic. At the same time, photoelectric sensors can also detect the color and shape of objects. The advantage of photoelectric sensors is that they are suitable for non-metallic materials and can detect the color and shape of objects. However, the transmission distance of light is short and the requirements for the environment are high.

[0052] The utility model utilizes two metal sensors 7 to detect the roller 2. Once the roller 2 is entangled with the waste belt, the metal sensor 7 can find the difference between the waste belt and the roller 2, thereby starting the automatic cutting component 6, using the cutter to cut off the waste belt on the roller 2, and then the automatic absorption component 8 will absorb the cut waste belt; the above mechanism can automatically detect whether the roller 2 is entangled with the waste belt, and then determine whether the cutting and absorption work is needed according to the detection result. It has a high degree of automation and can promptly and effectively deal with the problem of the waste belt winding around the roller 2 without stopping the machine for manual processing, which will no longer affect the working efficiency of the equipment.

[0053] On the basis of the above technical solution, the automatic cutting component 6 comprises:

[0054] Linear drive, there are many ways to implement linear drive, such as hydraulic cylinder, pneumatic cylinder, electric push rod, ball screw or smooth rod cable traverser, etc., and the corresponding driving methods of the above methods are also different. Among them, hydraulic cylinder and pneumatic cylinder are similar, both of which realize action by pressurizing or depressurizing the fluid, and are controlled by various valve bodies. Electric push rods and ball screws are realized by the forward and reverse rotation of the motor. The smooth rod cable traverser is similar to the electric push rod and ball screw, the only difference is that the motor does not need to be reversed;

[0055] Cutter, the cutter is arranged on the top surface of the slide of the linear drive. The slide in this example refers to a part connected to the linear drive and used to fix the cutter. When the linear drive is a hydraulic cylinder, a pneumatic cylinder or an electric push rod, the slide is connected to the end of their piston rod. When the linear drive is a ball screw, the slide is connected to the ball nut. When the linear drive is a bare rod cable arranging device, the slide is a fixed platform on the bare rod cable arranging device that can reciprocate. Regardless of the form of the slide, the role of the slide is to drive the cutter to achieve reciprocating motion.

[0056] In addition, if Figure 1 and Figure 2 As shown, the slide in the embodiment of the present application is realized in the form of a ball screw, and the forward and reverse rotation of the ball screw is controlled by the motor on the outside of the frame 1 to realize back and forth movement. In order to prevent the slide from deflecting, a slide bar is also provided under the ball screw, and the slide is sleeved on the slide bar, so as to ensure that the cutter on the slide and the lower edge of the roller 2 always remain tangent to each other, so as to improve the reliability of the present application.

[0057] Finally, the slide can perform linear reciprocating motion on the linear drive to drive the cutter to cut the waste belt.

[0058] On the basis of the above technical solution, the two automatic absorption components 8 are respectively fixed on the inner walls on both sides of the frame 1, or the two automatic absorption components 8 are respectively fixed on both sides of the automatic cutting component 6.

[0059] There are multiple implementation methods for the setting, connection and control of the automatic absorption component 8, and the installation position of the automatic absorption component 8 can be selected according to usage requirements.

[0060] The automatic absorption component 8 mentioned above comprises:

[0061] Suction nozzle;

[0062] A suction pump and a suction pipeline, one end of the suction pipeline is connected to the suction nozzle, and the other end is connected to the suction pump, and the suction pump is used to create negative pressure and provide suction to suck the waste belt;

[0063] The suction pump and / or the suction pipeline are provided with a filter, which can prevent the suction pump from being damaged by the waste belt.

[0064] The suction nozzle should preferably be trumpet-shaped, because the diameter of the suction pipeline and the power of the suction pump will affect the suction pressure. When the power of the suction pump remains unchanged, the smaller the diameter of the suction pipeline, the greater the suction pressure will be, and the waste belt itself is not wide, so it is more appropriate to use a small diameter suction pipeline. However, a small suction pipeline will result in a small suction range, so a trumpet-shaped suction nozzle can expand the suction range.

[0065] In combination with the installation position and structure of the automatic absorption component mentioned above, the automatic absorption component 8 has multiple installation positions. The preferred solution is to use an air suction pump to connect the two suction nozzles through two parallel suction pipes to provide suction; the suction nozzle can be fixed on the frame 1 so that the two suction nozzles work continuously; the two suction nozzles can also be respectively arranged on both sides of the automatic cutting-off component 6, and proximity switches are arranged on the inner walls on both sides of the frame 1, and a switch valve is arranged on the suction pipe, and the proximity switch is used to control the on and off of the switch valve. When the suction nozzle on any side of the automatic cutting-off component 6 approaches the inner wall of the frame 1, the proximity switch works to control the corresponding suction nozzle to absorb the waste belt. The purpose of this design is to save energy and avoid waste.

[0066] On the basis of the above technical solution, waste suction pipes 5 are provided on the inner walls of both sides of the frame 1, and the pipe openings of the two waste suction pipes 5 are respectively facing the two sides of the top edge of the roller 2;

[0067] The waste suction pipe 5 is connected to the air suction pipeline.

[0068] Before the winding device works, the thread ends of the waste tape are first placed in the waste suction pipe 5. When the winding device works, the waste suction pipe 5 continuously provides suction. The waste tape is sucked by the waste suction pipe 5 to reduce the probability of the waste tape being wound around the roller 2. In addition, this structure can also collect the waste tape and prevent it from falling to the ground.

[0069] On the basis of the above technical solution, the cutting knife is a single-edged sharp knife, a double-edged sharp knife or a rotatable round knife.

[0070] Different cutters have different cutting efficiencies. Double-edged sharp knives and round knives can cut while the slide is reciprocating, while single-edged sharp knives can only cut on one side.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
