[0002] The metallized film slitting device is a mechanical device used to cut wide metallized films (such as aluminum-plated films, chrome-plated films, etc.) into narrow strips of required width. The metallized film slitting device with sliding feeding realizes the input of materials through a sliding mechanism to ensure that the film can remain flat and stable when entering the cutting area.

Especially in the case of high-speed cutting or continuous long-term work, this friction may cause the tool temperature to rise. The metal layer in the metallized film may melt and adhere to the tool at high temperature. The heated tool may cause the film to deform, affecting the subsequent cutting effect.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0031] Example 1

[0032] like Figure 1 As shown, Figure 1 What is shown is an overall schematic diagram of the striping device in the embodiment;

[0033] The metallized film slitting device with sliding feeding includes:

[0034] The conveying structure and the slitting structure 20, the conveying structure comprises a discharge roller 11 and a conveyor belt 12;

[0035] The slitting structure 20 is arranged above the conveyor belt 12, and a metallized film is wound on the unwinding roller 11. The metallized film is pulled by using the unwinding roller 11 and the winding roller, and the metallized film is transported along the conveyor belt 12 to the slitting structure 20 for slitting.

[0036] like Figure 2 As shown, Figure 2 What is shown is a schematic diagram of the cutting structure in the embodiment;

[0037] The slitting structure 20 includes a fixed frame 21, a knife seat 22 is provided inside the fixed frame 21 for lifting, and a plurality of knives 23 arranged at intervals are provided at the bottom of the knife seat 22;

[0038] The fixing frame 21 is n-shaped, and a plurality of cutters 23 realize the stripping operation of the metallized film;

[0039] like Figure 2 , Figure 3 As shown, Figure 2 What is shown is a schematic diagram of the cutting structure in the embodiment; Figure 3 What is shown is a schematic diagram of the structure of the cooling channel in the embodiment;

[0040] The cooling assembly further comprises a liquid storage tank 31, which is fixedly arranged at the top of the inner side of the fixing frame 21, and an outlet pipe 32 and a return pipe 33 are respectively arranged on both sides of the liquid storage tank 31, and an outer sleeve 34 is arranged at one end of the outlet pipe 32 and the return pipe 33 away from the liquid storage tank 31, and an inner sleeve 35 is movably inserted inside the other end of the outer sleeve 34, and the other end of the inner sleeve 35 is connected to the top of the tool holder 22, and a cooling groove 36 is arranged inside the tool holder 22, and the cooling groove 36 is arranged at a position close to the root of the tool holder 22, and a connected cooling channel is formed inside the outlet pipe 32, the outer sleeve 34, the inner sleeve 35, the cooling groove 36 and the return pipe 33.

[0041] The liquid storage tank 31 is used to store coolant, and a water pump is also provided inside the liquid storage tank 31. The water pump realizes the circulation of the coolant in the cooling channel. The coolant flowing through the cooling groove 36 cools the tool 23: when the coolant flows through the cooling groove 36 in the tool holder 22, the coolant is in direct contact with the root of the tool 23, and the heat on the tool 23 is transferred to the coolant through heat conduction. Since the temperature of the coolant is relatively low, the heat will be transferred from the high-temperature tool to the low-temperature coolant, thereby reducing the temperature of the tool.

[0042] By taking away the heat through the cooling component, the working temperature of the cutter 23 can be effectively reduced, the thermal stress and thermal deformation can be reduced, thereby extending the service life of the cutter 23, and preventing the metallized film material from being deformed due to high temperature, ensuring that the cutting edge is smooth, burr-free, and non-adhesive, thereby improving the quality of the cut product. In addition, the downtime caused by overheating of the cutter 23 can be reduced, and the continuity and efficiency of the slitting work can be improved.

[0043] The tool holder 22 and the tool 23 switch between the working state and the non-working state by lifting and lowering. Specifically, the tool 23 is in the working state when it descends to a specific position, and is in the non-working state when it is raised. The outer sleeve 34 and the inner sleeve 35 that are movably matched can play a guiding role in the lifting process of the tool holder 22, and when the inner sleeve 35 slides inside the outer sleeve 34, it does not affect the circulation of the coolant in the inner cavity of the outer sleeve 34 and the inner sleeve 35.

[0044] like Figure 2 As shown, Figure 2 What is shown is a schematic diagram of the cutting structure in the embodiment;

[0045] A displacement sensor 41 is also provided at the bottom of the inner side of the fixing frame 21, and a controller 42 is provided at the top of the outer side of the fixing frame 21. The controller 42 is electrically connected to the displacement sensor 41.

[0046] The water pump in the liquid storage tank 31 is provided with a solenoid valve, and the controller 42 is connected to the water pump solenoid valve signal to control the opening and closing of the water pump.

[0047] Specifically, the displacement sensor 41 corresponds to the working state position of the tool 23 and is used to detect whether the tool 23 is in the working position. The displacement sensor 41 transmits the detection result to the controller 42 through detection, and the controller 42 controls the water pump to open or close according to the detection result.

[0048] By setting up structures such as the displacement sensor 41 and the controller 42, when the tool 23 is in a working state, the water pump is controlled to open so that the coolant circulates to continuously cool the tool 23. When the tool 23 is in a non-working state, the water pump is turned off to stop the circulation of the coolant.

[0049] This design allows the coolant to flow only when the tool 23 is actually working, thereby avoiding unnecessary coolant consumption and overcooling of the tool 23, reducing energy waste, and being more energy-saving and environmentally friendly.

[0050] like Figure 3 , Figure 4 , Figure 5 As shown, Figure 3 What is shown is a schematic diagram of the structure of the cooling channel in the embodiment; Figure 4 It shows Figure 3 A schematic diagram of the enlarged structure in the middle; Figure 5 Shown is a schematic diagram of the position of the drain valve on the knife seat;

[0051] The end of the inner sleeve 35 located inside the outer sleeve 34 is also sleeved with a blocking sleeve 37;

[0052] The bottom end surface of the tool holder 22 is in an arc shape, and a drain valve 38 connected to the cooling groove 36 is provided at the lowest point. The drain valve 38 is connected to the controller 42 by signal.

[0053] When the tool 23 is in a non-working state, the tool 23 rises, and the inner sleeve 35 slides to the highest point inside the outer sleeve 34. The blocking sleeve 37 is provided, and the blocking sleeve 37 can block the inner cavity ends of the outlet pipe 32 and the return pipe 33, thereby cutting off the flow path of the coolant, so that the coolant cannot flow into the outer sleeve 34, and the circulation of the coolant is stopped. At this time, the controller 42 controls the water pump to close and opens the drain valve 38 at the same time, so that the coolant remaining in the outer sleeve 34, the inner sleeve 35 and the cooling tank 36 is drained.

[0054] If the coolant stays in the circulation path for a long time, it may cause the accumulation of scale, minerals or other deposits, affecting the cooling effect and increasing the difficulty of maintenance. By cutting off the coolant circulation path and draining the residual coolant, the accumulation of these substances can be reduced, keeping the system clean and running efficiently, and reducing the contact time between the coolant and the cooling channel to prevent corrosion.

[0055] In addition, if the equipment needs to use different types of coolants (such as water-based coolant and oil-based coolant), draining the coolant can easily switch the coolant type and avoid mixing and contamination between different coolants.

[0056] Specifically, the drain valve 38 is externally connected to a drain pipe, which can discharge the discharged coolant to a specific place for recovery or treatment.

[0057] like Figure 2 As shown, Figure 2 What is shown is a schematic diagram of the cutting structure in the embodiment;

[0058] Extension plates 51 are provided on both sides of the knife seat 22 , and a driving member 52 is provided on the inner side wall of the fixing frame 21 . The output end of the driving member 52 is connected to the extension plates 51 , and the driving member 52 drives the knife seat 22 to move up and down.

[0059] The driving member 52 is a cylinder, a hydraulic cylinder, etc., which can play a driving role to move the knife holder 22 up and down to switch between a working state and a non-working state.

[0060] Working principle: When the device is in use, the metallized film is conveyed to the slitting structure 20 through the conveying structure, the driving member 52 is started, the knife holder 22 is driven to move downward close to the metallized film, and the knife 23 cuts the metallized film. At the same time, the displacement sensor 41 detects the position state of the knife 23 to determine that the knife 23 is in a working state and transmits the signal to the controller 42. The controller 42 controls the water pump to turn on, and the coolant circulates in the cooling channel to cool the knife 23, that is, the coolant flows out from the water outlet pipe 32 of the liquid storage tank 31, passes through the knife holder 22, and finally returns from the return pipe 33;

[0061] When the cutting is completed and the tool 23 is in a non-working state, the driving member 52 is started to drive the tool holder 22 to move upward to the initial position. At this time, the inner sleeve 35 slides to the highest point inside the outer sleeve 34, and the blocking sleeve 37 of the inner sleeve 35 blocks the inner cavity ends of the outlet pipe 32 and the return pipe 33, thereby cutting off the flow path of the coolant. At the same time, the displacement sensor 41 detects the position state of the tool 23 to determine that the tool 23 is in a non-working state and transmits the signal to the controller 42. The controller 42 controls the water pump to turn off and controls the drain valve 38 of the tool holder 22 to open. At this time, the coolant stops circulating and the remaining coolant in the cooling tank 36 is drained.

[0064] S1, the metallized film is transported to the slitting structure 20, and the cutter 23 descends to slit the metallized film;

[0065] S2, the displacement sensor 41 detects that the tool 23 is in working state;

[0066] S3, the displacement sensor 41 transmits a signal to the controller 42, and the controller 42 starts the coolant circulation to cool the tool 23;

[0067] S4, stripping is completed, and the cutter 23 rises to the initial position;

[0068] S5, the displacement sensor 41 detects that the tool 23 is in a non-working state;

[0069] S6. The displacement sensor 41 transmits a signal to the controller 42, and the controller 42 closes the coolant circulation to save energy.
