Description

Technical Field

[0001] This utility model relates to the field of packaging bag cutting, specifically to a battery packaging bag cutting device. Background Technology

[0002] In the battery production packaging process, cutting the battery packaging bag is a crucial step after sealing. Battery packaging bags are typically rolls of composite film, which need to be cut into individual sheets of specific sizes according to the battery specifications before subsequent battery sealing operations can proceed. The cutting accuracy directly affects the quality of the subsequent sealing process. If the cutting dimensions deviate too much, the edges of the packaging bag may not match the battery, resulting in incomplete sealing or excessive stretching. If the cut edges are uneven, it may cause poor sealing during sealing, increasing the risk of the battery getting damp or short-circuiting.

[0003] Currently, the packaging bag cutting equipment commonly used in the battery industry is mainly divided into two categories: manual cutting tools and semi-automatic cutting machines. Manual cutting tools are flexible to operate, but the cutting accuracy depends entirely on the operator's experience, making it difficult to guarantee that each battery packaging bag is the same size for mass production.

[0004] Therefore, it is very necessary to provide a battery packaging bag cutting device to solve the above-mentioned technical problems. Utility Model Content

[0005] Based on the above description, this utility model provides a battery packaging bag cutting device to solve the problem that while existing manual cutting tools are flexible to operate, their cutting accuracy depends entirely on the operator's experience, making it difficult to guarantee the consistent size of each battery packaging bag for mass production.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A battery packaging bag cutting device includes a bottom plate and a cutting component connected to the bottom plate. The cutting component includes a lower cutting blade connected to the bottom plate. A guide is connected to the bottom plate, and an upper cutting blade is connected to the guide. The guide is used to drive the upper cutting blade to move up and down, thereby cutting the battery packaging under the action of the upper cutting blade and the lower cutting blade.

[0007] Furthermore, the guide includes a sliding guide rail, and two sliding guide rails are provided. The two sliding guide rails are symmetrically connected to both sides of the bottom plate, and guide sleeves are slidably connected to the sliding guide rails.

[0008] Furthermore, a connecting plate is connected to the guide sleeve, and the upper cutting blade is connected to the connecting plate.

[0009] Furthermore, an upper horizontal plate is connected between the two sliding guide rails, and a secondary pneumatic rod is connected to the upper horizontal plate. The telescopic end of the secondary pneumatic rod is connected to the connecting plate.

[0010] Furthermore, a spring damper is connected between the telescopic end of the secondary pneumatic rod and the connecting plate.

[0011] Furthermore, a pressure sensor is connected between the spring damper and the connecting plate.

[0012] Furthermore, a controller is connected to the upper horizontal plate.

[0013] Furthermore, an alarm is connected to the upper horizontal plate.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] The guide design provides a precise guide path for the up-and-down movement of the upper cutting blade. During the cutting process, the upper cutting blade moves strictly according to the trajectory set by the guide, precisely cooperating with the lower cutting blade, effectively avoiding problems such as uneven cutting and large dimensional errors caused by cutting blade movement deviation. This allows the cutting dimensions of the battery packaging bags to meet design requirements with high precision, ensuring product consistency and quality stability. The bottom plate provides a stable foundation support for the entire cutting device, while the lower cutting blade is firmly connected to the bottom plate. During cutting, this stable structure effectively reduces vibration and shaking generated during the cutting process, making the cutting action between the upper and lower cutting blades smoother and more stable, further improving cutting accuracy and ensuring smooth and neat cutting edges without defects such as burrs and wrinkles. This solves the problem that existing manual cutting tools are flexible to operate, but the cutting accuracy depends entirely on the operator's experience, making it difficult to guarantee the consistent size of each battery packaging bag in mass production.

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0021] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "above," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features.

It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0024] As shown in the figure, a battery packaging bag cutting device includes a bottom plate 1 and a cutting component 2 connected to the bottom plate 1. The cutting component 2 includes a lower cutting blade 3 connected to the bottom plate 1. A guide 4 is connected to the bottom plate 1, and an upper cutting blade 5 is connected to the guide 4. The guide 4 is used to drive the upper cutting blade 5 to move up and down, thereby cutting the battery packaging under the action of the upper cutting blade 5 and the lower cutting blade 3.

[0025] In this embodiment, the guide member 4 provides a precise guiding path for the up-and-down movement of the upper cutting blade 5. During the cutting process, the upper cutting blade 5 can move strictly according to the trajectory set by the guide member 4, precisely cooperating with the lower cutting blade 3, effectively avoiding problems such as uneven cutting and large dimensional errors caused by cutting blade movement deviation. This allows the cutting size of the battery packaging bag to meet the design requirements with high precision, ensuring product consistency and quality stability. The bottom plate 1 provides a stable foundation support for the entire cutting device, and the lower cutting blade 3 is firmly connected to the bottom plate 1. During cutting, this stable structure can effectively reduce the shaking and swaying generated during the cutting process, making the cutting action between the upper cutting blade 5 and the lower cutting blade 3 more stable and smooth, further improving the cutting accuracy, and ensuring that the cutting edge is smooth and neat, without defects such as burrs and wrinkles. In addition, the bottom plate 1 is placed on the placement platform 11.

[0027] In some embodiments, a connecting plate 8 is connected to the guide sleeve 7, and the upper cutting blade 5 is connected to the connecting plate 8.

[0028] In some embodiments, an upper horizontal plate 9 is connected between the two sliding guide rails 6, and a secondary pneumatic rod 10 is connected to the upper horizontal plate 9. The telescopic end of the secondary pneumatic rod 10 is connected to the connecting plate 8.

[0029] In some embodiments, a spring damper 11 is connected between the telescopic end of the secondary pneumatic rod 10 and the connecting plate 8.

[0030] In some embodiments, a pressure sensor 12 is connected between the spring damper 11 and the connecting plate 8.

[0031] In some embodiments, a controller 13 is connected to the upper horizontal plate 9.

[0032] In some embodiments, an alarm 14 is connected to the upper horizontal plate 9.

[0033] Example 1:

[0034] The bottom plate 1 is forged from 45# steel and its surface is hardened. The upper surface is provided with a milling groove for embedding the lower cutting blade 3. The lower cutting blade 3 is a carbide insert, which is fixed to the bottom plate 1 with screws. The cutting edge is higher than the bottom plate and the cutting edge is precision ground.

[0035] The sliding guide rail 6 is a linear guide rail, symmetrically fixed to both sides of the bottom plate 1 with screws. The guide sleeve 7 uses matching sliders, which are clearance-fitted with the sliding guide rail 6. Two sliders are installed on each guide rail, and threaded holes are opened on the side of the sliders for connecting the connecting plate 8. The connecting plate 8 is an aluminum alloy plate, fixed to the guide sleeve 7 at both ends with screws. A T-slot is opened in the center of the lower surface for installing the upper cutting blade 5. The upper horizontal plate 9 is a rectangular steel tube welded structure, fixed to the top of the two sliding guide rails 6 at both ends by welding. A two-stage pneumatic rod 10 is installed on the upper surface. A double-acting cylinder is selected. The cylinder body is connected to the upper horizontal plate 9 through a flange, and the piston rod is vertically downward.

[0036] The spring damper 11 uses a cylindrical helical spring. Its upper end is connected to the piston rod of the secondary pneumatic rod 10 via a threaded connector, and its lower end is threaded to the upper surface of the pressure sensor 12. The lower surface of the pressure sensor 12 is fixed to the connecting plate 8 with screws. The signal line is connected to the controller 13 through the wire hole in the upper horizontal plate 9. The controller 13 uses a PLC, model Mitsubishi FX3U-64MR / ES-A, installed in the control box on the side of the upper horizontal plate 9. The panel has operation buttons, start / stop / emergency stop buttons, and a touch screen for setting cutting parameters. The alarm 14 is an audible and visual alarm, fixed to the top surface of the upper horizontal plate 9 with M6 screws and electrically connected to the controller 13. It emits a red flash and sounds an alarm when the pressure is abnormal. Connect the air source and power supply, turn on the power switch of the controller 13, and the touch screen displays the initial interface.

[0037] Specific implementation method of this application:

[0038] Lay the battery packaging bag to be cut flat on the bottom plate 1, aligning the cutting area with the blade of the lower cutting blade 3. Push the packaging bag so that its edge fits against the positioning baffle on the side of the bottom plate 1, ensuring accurate cutting.

[0039] Pressing the "Start" button on controller 13 extends the piston rod of the secondary pneumatic rod 10, causing the connecting plate 8 to move downwards along the sliding guide rail 6. The upper cutting blade 5 descends with the connecting plate 8, and as it approaches the lower cutting blade 3, the spring damper 11 begins to compress, providing cushioning force.

[0040] When the pressure sensor 12 detects that the pressure has reached the set value, the controller 13 sends a signal, and the secondary pneumatic rod 10 pauses its descent for 0.5 seconds to complete the cutting action.

[0041] After the pressure holding time ends, the controller 13 controls the piston rod of the secondary air pressure rod 10 to retract, driving the upper cutting blade 5 to rise and reset.

[0042] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0043] The guide design provides a precise guide path for the up-and-down movement of the upper cutting blade. During the cutting process, the upper cutting blade moves strictly according to the trajectory set by the guide, precisely cooperating with the lower cutting blade, effectively avoiding problems such as uneven cutting and large dimensional errors caused by cutting blade movement deviation. This allows the cutting dimensions of the battery packaging bags to meet design requirements with high precision, ensuring product consistency and quality stability. The bottom plate provides a stable foundation support for the entire cutting device, while the lower cutting blade is firmly connected to the bottom plate. During cutting, this stable structure effectively reduces vibration and shaking generated during the cutting process, making the cutting action between the upper and lower cutting blades smoother and more stable, further improving cutting accuracy and ensuring smooth and neat cutting edges without defects such as burrs and wrinkles. This solves the problem that existing manual cutting tools are flexible to operate, but the cutting accuracy depends entirely on the operator's experience, making it difficult to guarantee the consistent size of each battery packaging bag in mass production.
