Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of plastic film production, especially relates to a cutting machine for plastic film production. BACKGROUND

[0002] Plastic film cutting technology is widely used in packaging, printing, electronic products, medical supplies and other fields. With the increasing demand for plastic film, the performance of the cutting machine on the production line is becoming more and more demanding, especially in improving cutting quality, reducing waste rate and improving production efficiency. Traditional plastic film cutting machine generally relies on mechanical blade or ultrasonic technology for cutting, however, these traditional cutting methods have certain limitations when facing certain types of plastic film.

[0003] The cutting of plastic film is often affected by its material properties and surface state. Most plastic films have smooth surfaces and are prone to stretching, tearing and other problems during cutting. Because plastic film is hard and brittle at cold state, the cutting blade is difficult to penetrate smoothly, resulting in unsatisfactory cutting effect. Especially when fine cutting of thin or soft plastic film, uneven cutting, rough edges, tearing and other phenomena often occur, affecting the appearance quality of the product and subsequent processing procedures.

[0004] Currently, most plastic film cutting machines on the market rely on mechanical blades or ultrasonic cutting technology. Although mechanical blades can achieve high efficiency cutting, they often generate a lot of cutting resistance during the cutting process, resulting in increased friction between the blade and the film, increasing the risk of uneven cutting. In addition, mechanical blades have poor adaptability to different materials and thicknesses of plastic film, and are prone to tearing and stretching of the plastic film surface during cutting.

[0005] Heated blade technology has gradually gained attention in the industrial field in recent years. By heating the blade to a certain temperature, the resistance generated during cutting can be effectively reduced, making it easier for the blade to cut into the plastic film. The heated blade can soften the surface of the plastic film, reducing tearing, stretching and other adverse phenomena caused by hard and brittle materials. Through appropriate temperature control, the cutting surface can be smoother and more uniform, thereby improving cutting quality and production efficiency.

[0006] However, most plastic film cutting machines on the market do not have the blade heating function. Although some high-end equipment has heating function, its cost is high, and there are some difficulties in technical implementation, mainly in the precise control of heating temperature. Different types of plastic film have different softening temperatures, which makes it difficult for many plastic film production enterprises to effectively solve the problem of unstable cutting quality when facing different types of film materials.

It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0057] Embodiment 1:

[0058] As Figures 1-5 shown, the present embodiment provides a cutting machine for plastic film production, comprising:

[0059] a bottom plate 1;

[0060] a fixed frame 2 arranged on the top of the bottom plate 1 on both sides;

[0061] a workbench 21 arranged between the two fixed frames 2 for supporting the input plastic film;

[0062] a support frame 3 arranged on the bottom plate 1;

[0063] The heating system 4 is arranged on the bottom plate 1 and the support frame 3, and the two heating systems 4 are symmetrically distributed in an up-down direction.

[0064] The blade assembly 5 is arranged on the heating system 4, and the heating system 4 heats the blade assembly 5; the blade assembly 5 is used for cutting the plastic film.

[0065] The temperature control system 6 is used for monitoring and controlling the temperature of the blade assembly 5, so that the temperature of the blade assembly 5 is kept within a preset range.

[0066] The driving system 7 cooperates with the blade assembly 5 and is used for driving the blade assembly 5 to cut the plastic film.

[0067] In the technical solution, the heating system 4 is combined with the blade assembly 5, so that the blade can maintain an appropriate temperature during cutting, which can effectively reduce the resistance caused by film adhesion or unevenness during cutting and improve the cutting efficiency. Hot cutting helps to make the plastic film cut smooth and neat, and avoids rough or broken cutting edges caused by excessively high or low temperature. The design of the temperature control system 6 ensures that the blade is always within an appropriate temperature range, thereby avoiding cutting problems caused by excessively high or low temperature, and effectively preventing safety hazards caused by equipment failure or unstable temperature. Through the precise control of the temperature control system 6 on the heating system 4, the working requirements can be met while avoiding excessive heating, saving energy consumption, and improving the intelligent level of the equipment.

[0068] Work flow: First, the plastic film to be cut is fed into the workbench 21 through the feeding system (not specifically mentioned in the description); the workbench 21 provides stable support to ensure the smooth and smooth input of the film. When the film is input in place, the heating system 4 starts to work, which is composed of upper and lower two parts, uniformly heating the blade assembly 5, ensuring that the blade reaches the appropriate temperature during cutting, thereby ensuring the smoothness and precision of the cutting effect. The temperature control system 6 monitors the temperature of the blade in real time and adjusts it as needed; the temperature control system 6 ensures that the temperature of the blade is maintained within a predetermined range, avoiding difficulties in cutting due to low temperature, or affecting the quality of the film due to excessive heating caused by high temperature. Through the driving system 7, the blade assembly 5 starts and begins to cut the film after heating, and the driving system 7 may be through mechanical devices to realize the relative movement of the blade, to ensure the stability and force of the blade when cutting the film accurately. When the blade completes the cutting work, the cut film is transported to the next process, and throughout the working process, the temperature control system 6 will continuously adjust the temperature of the blade to ensure that it is within the preset range, and the driving system 7 will also adjust the working force according to the cutting situation to avoid uneven cutting, excessive friction and other problems. The plastic film cutting machine provides an efficient, accurate and stable cutting process through heating, temperature control and precise mechanical driving system 7. The combination of heating system 4 and temperature control system 6 ensures the rationality of the blade temperature during cutting, avoiding cutting problems caused by inappropriate temperature. In addition, the driving system 7 ensures the cutting force and precision, and the coordinated work of the whole system can significantly improve the production efficiency and product quality, which is an ideal equipment suitable for efficient production.

[0069] Specifically, the bottom plate 1 is the support structure of the cutting machine, the fixing frame 2 is located at the top of both sides of the bottom plate 1, and the stability of the workbench 21 is ensured through the support frame 3 to ensure that the film cutting is not disturbed by the outside world. The heating system 4 provides heat to make the blade temperature reach the preset working state, which is crucial for the cutting of plastic film. Too low temperature will increase the cutting resistance, and too high temperature may cause film deformation or uneven cutting. The blade assembly 5 is the main tool for cutting film, which needs to withstand the power from the driving system 7 in design, and at the same time, due to the action of the heating system 4, the blade has good heat treatment capacity, ensuring that the appropriate temperature is maintained during the cutting process, avoiding film adhesion or damage. The temperature control system 6 monitors and adjusts the temperature of the blade in real time to ensure that it is within a stable and appropriate temperature range. The temperature control system 6 usually includes sensors, control units and heating elements, which automatically adjust the working state of the heating system 4 through a feedback mechanism. The driving system 7 is responsible for transmitting power to the blade assembly 5 to ensure that the blade can apply appropriate pressure to cut the film when it contacts the film. The driving method can include electric motor, pneumatic cylinder, etc., which is adjusted according to the cutting precision requirements.

[0070] AsFigure 1 and Figure 2 As shown in

[0071] In this technical solution, the power supply of the heating system 4 is connected to the L-shaped heater 42 through the heater lead 43. When the system is powered on, the heater starts to work and transfers heat to the heating part 41 and the blade assembly 5 through electric energy. The L-shaped heater 42 is designed to evenly distribute heat to each area of the heating part 41. The heat is transferred to the blade assembly 5 through the heating part 41, ensuring that the blade surface can be uniformly heated. The blade assembly 5 on the heating part 41 gradually warms up under the action of heat, and the temperature gradually and evenly distributes on the blade surface, thereby avoiding cutting problems caused by local temperature that is too low. Proper heat helps to reduce the friction between the blade and the film, allowing the blade to cut the film more smoothly and reducing the wear rate of the blade during cutting. With the help of heating, the blade temperature is appropriate, and the blade can maintain sharpness and precision when cutting the film, avoiding uneven cutting or jamming caused by inappropriate temperature. The blade can efficiently and stably cut under temperature control. Through uniform heating, the cutting effect is improved, thereby improving the production efficiency.

[0072] As shown in Figures 1-3 In this embodiment, the optimized blade assembly 5 comprises:

[0073] A cutting knife 51 is arranged on the heating part 41, and the cutting knife 51 is symmetrically arranged in an up-down direction.

[0074] A fixing hole 52 is formed in the cutting knife 51, and the fixing hole 52 has a plurality of holes and is uniformly and spacedly arranged along the length direction of the cutting knife 51.

[0075] A positioning hole 53 is formed in the heating part 41, and the positioning hole 53 is consistent in number with the fixing hole 52 and corresponds to the fixing hole 52 one by one.

[0076] A rivet 54 is arranged through the fixing hole 52 and the positioning hole 53 to fix the cutting knife 51 on the heating part 41.

[0077] In the technical solution, first, the cutting knife 51 is placed on the heating part 41, and the fixing holes 52 on the cutting knife 51 are in one-to-one correspondence with the positioning holes 53 on the heating part 41. According to the design requirements, the number and spacing of the fixing holes 52 and the positioning holes 53 should be accurately matched. Then, the fixing holes 52 of the cutting knife 51 and the positioning holes 53 of the heating part 41 are connected by rivets 54, and the use of rivets 54 ensures the stability of the cutting knife 51 and prevents it from loosening or mispositioning during use. After the cutting knife 51 is fixed, the combination with the heating part 41 ensures the thermal stability of the cutting tool. The heat of the heating part 41 can be conducted to the cutting knife 51, helping to improve the temperature of the cutting tool, so that the cutting tool can effectively cut the plastic film, reduce the friction force, tool wear and cutting resistance. When the cutting knife 51 contacts the film, the plastic film is smoothly cut by the sharpness of the cutting tool and the heating effect. Due to the stable fixation of the cutting tool, the mechanical state during cutting remains stable, thereby ensuring the cutting precision and quality. Due to the fixing effect of the rivets 54, the cutting blade is not easy to loosen or deform, so the cutting machine can maintain high stability and cutting precision for a long time, reducing the frequency of maintenance and adjustment. Through the precise fixing and positioning structure, the efficient and accurate operation of the cutting knife 51 is ensured, and the cutting quality is improved through the cooperation of the heating part 41. Through the fixed mode of the rivets 54, the position of the cutting tool can be stabilized, the maintenance demand is reduced, and the cutting knife 51 can be easily disassembled and replaced, thereby improving the overall performance and production efficiency of the cutting machine.

[0078] As shown in Figure 5 In this embodiment, the optimized temperature control system 6 includes a temperature sensor 61 for real-time monitoring of the temperature of the blade assembly 5 and a temperature controller 62 for adjusting the heating power of the heating system 4 according to the feedback signal of the temperature sensor 61 to ensure that the blade assembly 5 operates within the preset temperature range.

[0079] In the present technical solution, after the cutting machine is started, the temperature sensor 61 begins to monitor the temperature of the blade assembly 5 in real time. The sensor continuously transmits the actual temperature data of the blade to the temperature controller 62, ensuring that the temperature control system 6 can obtain the temperature information of the blade at any time. The feedback signal of the temperature sensor 61 is transmitted to the temperature controller 62, and the controller determines whether the current temperature is within a reasonable range according to the preset temperature range. If the temperature is lower than the preset lower limit, the temperature controller 62 will issue an instruction to increase the power of the heating system 4, so that the heater provides more heat to quickly raise the temperature of the blade. If the temperature exceeds the preset upper limit, the temperature controller 62 will reduce or cut off the heating power to prevent the blade temperature from being too high. According to the instructions of the temperature controller 62, the heating system 4 starts to adjust the heating power accordingly. The heating system 4 can change the power output of the heating element to ensure that the temperature of the blade assembly 5 is within the appropriate range. The temperature sensor 61 and the temperature controller 62 continuously interact, real-time detect the temperature change of the blade and adjust the heating power, to ensure that the temperature is always maintained within the preset range. When the environment changes or external factors affect the temperature of the blade, the system will respond quickly according to the temperature feedback to maintain the temperature stability of the cutting machine. After the temperature is stable, the cutting function of the blade assembly 5 is guaranteed, and the cutting machine can start stable and efficient cutting work of the plastic film. At this time, the temperature control function of the system ensures the accuracy, stability and efficiency of the cutting, and ensures the quality and production efficiency of the film.

[0084] The push plate 72 is arranged on the electric push rod 71, and the push plate 72 is connected with the upper heating part 41 by bolt connection.

[0085] In the technical solution, when the plastic film needs to be cut, the electric push rod 71 is started, the position of the heating part 41 can be accurately adjusted through the pushing of the electric push rod 71, so as to drive the upper cutting knife 51 to ascend and descend and cooperate with the lower cutting knife 51 to cut the plastic film. Through the action of the electric push rod 71, the heating part 41 ensures that the heat is fully conducted to the surface of the blade, so that the temperature reaches the ideal cutting temperature, thereby improving the cutting effect. The temperature control system 6 and the driving system 7 work cooperatively to ensure that the heating part 41 always remains in the predetermined working range, avoiding the influence of too high or too low temperature on the cutting quality.

[0089] The mounting bracket 81 is arranged on the left and right sides of the top of the bottom plate 1;

[0090] The hopper 82 is arranged between the two mounting brackets 81, the hopper 82 is inclined and located in front of the cutting knife 51;

[0091] The outer frame 83 is arranged at the bottom of the bottom plate 1, and the upper end of the outer frame 83 penetrates and extends out of the bottom plate 1, and the outer frame 83 is located below the hopper 82;

[0092] The inner frame 84 is slidably arranged inside the outer frame 83;

[0093] The handle 85 is arranged on the inner frame 84;

[0094] The plastic film cut by the cutting knife 51 slides into the inner frame 84 inside the outer frame 83.

[0095] In the technical solution, the cutting machine is started, the cutting knife 51 cuts the plastic film according to the required size, the cut film falls into the discharge hopper 82 and starts to flow to the outlet of the discharge hopper 82. The discharge hopper 82 is designed to be inclined, and the cut film is guided to flow to the outer frame 83 by gravity. The front side position of the discharge hopper 82 ensures that the film can flow smoothly into the outer frame 83, avoiding any accumulation or jamming. The outer frame 83 plays a guiding and containing role, ensuring that the film can smoothly enter the inner frame 84. The structure and position of the outer frame 83 ensure that the flow of the film will not be hindered. The sliding design of the inner frame 84 ensures that when the inner frame 84 is full, it can be easily moved or removed for the collection of new film. When the film in the inner frame 84 accumulates to a certain extent, the operator can easily remove the inner frame 84 through the handle 85 on the inner frame 84 for subsequent processing or packaging.

[0096] Embodiment 4:

[0097] The embodiment provides a cutting machine for plastic film production, which has the following technical features in addition to the technical solutions of the above embodiments.

[0098] As shown in Figure 1 , Figure 2 and Figure 4 , in this embodiment, the optimized cutting machine for plastic film production also includes a smoothing assembly 9, which comprises:

[0099] A fixed plate 91 is arranged at the rear side of the support frame 3;

[0100] A rotating shaft 92 is rotatably arranged between the two fixed plates 91;

[0101] A support plate 93 is arranged on the rotating shaft 92;

[0102] A gas cylinder 94 is arranged on the support plate 93;

[0103] A connecting plate 95 is arranged on the piston rod of the gas cylinder 94;

[0104] A smoothing plate 96 is located above the workbench 21 and is used to smooth the plastic film passing through the workbench 21;

[0105] A vertical plate 97 is arranged on the top of the smoothing plate 96;

[0106] A pull rod 98 is arranged on the vertical plate 97, and the connecting plate 95 is movably connected with the pull rod 98.

[0107] In the present technical solution, the plastic film moves through the workbench 21 during production and is conveyed along the production line to the cutting machine. At this time, the film may have wrinkles or unevenness due to extrusion, winding or other mechanical forces. The combined structure of the air cylinder 94 and the connecting plate 95 is activated, the piston rod of the air cylinder 94 pushes the connecting plate 95 to move, so that the smoothing plate 96 moves along the direction of the workbench 21, and the smoothing plate 96 exerts a certain pressure and friction force on the film. Because the smoothing plate 96 is located above the workbench 21 and is combined with the pull rod 98 and the vertical plate 97, the smoothing plate 96 can accurately adjust the position and shape of the film to make it more flat. When the smoothing plate 96 moves above the workbench 21, it can smoothly straighten the wrinkled part of the plastic film. Due to the softness of the film, the smoothing plate 96 can play the role of smoothing and tensioning through contact with the film, reducing the uneven part. The effectiveness of this process depends on the cooperation of the air cylinder 94 and the pull rod 98 system, which ensures that the film always maintains a flat state on the workbench 21 and avoids any deformation. After the film is smoothed to the ideal state, it will continue to move along the workbench 21 and finally enter the cutting area of the cutting machine. In this area, the flat film will ensure the accuracy of the cutting process and the high-quality output. The smoothed film enters the cutting machine, activates the cutting mechanism, and accurately cuts the plastic film of the required size. Since the film has been smoothed before entering the cutting area, the cutting process will be smoother, reducing cutting errors caused by uneven film.
