Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a pneumatic cutting device for PE edge banding strips. Background Technology

[0002] PE edge banding strips are widely used for edge sealing in waterproof membranes, geotextiles, and other fields due to their corrosion resistance and flexibility. In the production line, continuous long strips of PE edge banding strips need to be cut into individual segments according to a preset length for subsequent use.

[0003] Currently, the industry commonly uses manual hand-held hacksaws to cut PE edge banding strips. This method has the following problems: First, it is labor-intensive, as the operator needs to hold the hacksaw the entire time and manually apply force to complete the sawing action, which can easily lead to fatigue after long periods of work. Second, manual sawing is slow, and each cut takes a long time, resulting in low efficiency. Third, the saw blade can easily cause tearing or burrs in the PE material, resulting in a rough and uneven cut surface, which affects the subsequent welding or overlapping sealing effect, and may even cause product defects. Fourth, it is risky to operate, as the cut surface of the hacksaw is completely exposed when cutting manually, and the saw blade can easily slip, the material can rebound, or the operator can lose control due to fatigue, resulting in serious work-related injuries such as arm cuts and tendon ruptures.

[0004] In summary, existing PE edge banding strip cutting equipment suffers from problems such as high labor intensity, low cutting efficiency, poor cut surface quality, and high operational risks. Utility Model Content

[0034] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0035] like Figures 1 to 7 As shown, the present invention provides a pneumatic cutting device for PE edge banding strips, including a mounting bracket 1 and a pneumatic scissors 2. The mounting bracket 1 includes a bottom support frame 11 and a cutting support plate 12 disposed on the top of the bottom support frame 11. The bottom support frame 11 is provided with a clamping member 13 for clamping and fixing the housing of the pneumatic scissors 2.

[0036] The cutting support plate 12 has an installation groove 14, and a cutting protection box 15 is fixedly installed in the installation groove 14. The cutting protection box 15 is a hollow box structure and is used to accommodate the cutting head of the pneumatic scissors 2.

[0037] The side wall of the cutting and protective box 15 is provided with an edge banding strip receiving groove 16, which is used to receive PE edge banding strips;

[0038] The PE edge banding pneumatic cutting device has a mounting bracket 1 consisting of a bottom support frame 11 and a cutting support plate 12 fixedly installed on the top of the bottom support frame 11. The cutting support plate 12 can be fixed to the top of the bottom support frame 11 by welding or bolting. A clamping member 13 is fixedly installed on the bottom support frame 11 to clamp the pneumatic scissors 2. The scissor head of the pneumatic scissors 2 is set inside the cutting protective box 15. The cutting protective box 15 has a hollow box structure, and the side wall of the cutting protective box 15 has an edge banding receiving groove 16 for accommodating PE edge banding.

[0039] The pneumatic cutting device for PE edge banding strips has a bottom support frame 11 that provides a stable foundation to prevent shaking or tipping during the cutting process and ensure safe and reliable operation. The bottom support frame 11 is used to support the cutting support plate 12 and other components (clamping parts 13, pneumatic scissors 2, cutting protection box 15, etc.) above it to ensure the integrity of the structure.

[0040] The cutting support plate 12 is installed on the bottom support frame 11 and is the main platform for installing the cutting protection box 15. It has a mounting groove 14 for installing the cutting protection box 15 and fixing the spatial position relationship between the clamping member 13 and the cutting protection box 15. This ensures the alignment accuracy between the blade of the pneumatic scissors 2 and the cutting protection box 15, and also ensures that the cutting path of the blade of the pneumatic scissors 2 is convenient for cutting the PE edge banding strip in the edge banding receiving groove 16.

[0041] The clamping member 13 is used to fix the housing of the pneumatic scissors 2 to prevent the pneumatic scissors 2 from shifting or shaking during operation, thus ensuring cutting accuracy and safety. In addition, the pneumatic scissors 2 is fixed by the clamping member 13, and its scissor head extends into the cutting protection box 15 and is aligned with the edge banding receiving groove 16, which facilitates the cutting of PE edge banding.

[0042] The cutting protection box 15 is fixedly installed in the mounting slot 14, that is, the mounting slot 14 provides installation space for the cutting protection box 15, ensuring the installation and fixation of the cutting protection box 15;

[0043] The cutting protection box 15 is placed in the mounting groove 14 on the cutting support plate 12. It is a hollow box structure, which is used to accommodate the cutting head of the pneumatic scissors 2. At the same time, it also has a binding strip receiving groove 16 for the PE binding strip to pass through. The cutting protection box 15 is a hollow box structure, which can completely surround the cutting head of the pneumatic scissors 2 in its internal cavity, which can effectively protect the cutting process and greatly improve the operational safety. In addition, it can also protect the cutting head of the pneumatic scissors 2 from external dust and oil stains to a certain extent. Moreover, the internal cavity structure of the cutting protection box 15 can limit the installation position of the cutting head of the pneumatic scissors 2 and ensure the uniformity of the closed position of the cutting head of the pneumatic scissors 2. The binding strip receiving groove 16 on the cutting protection box 15 is matched with the cutting path of the cutting head of the pneumatic scissors 2, so that the position of the binding strip receiving groove 16 on the cutting protection box 15 is fixed relative to the cutting head of the pneumatic scissors 2.

[0044] The binding strip receiving groove 16 on the cutting protective box 15 is used to restrict the PE binding strip to enter the cutting protective box 15 only from a specific position (the opening of the binding strip receiving groove 16), ensuring that the PE binding strip is in a fixed cutting position of the scissor head of the pneumatic scissors 2 every time it is cut. The operator only needs to push the PE binding strip into the binding strip receiving groove 16 to the required length mark to achieve precise fixed-length cutting; the binding strip receiving groove 16 can guide the PE binding strip smoothly into the working area, preventing the PE binding strip from twisting or shifting inside the box; the binding strip receiving groove 16 only allows the PE binding strip to move along its opening direction (i.e., into or out of the binding strip receiving groove 16), restricting other degrees of freedom of the PE binding strip near the cutting point and reducing cutting errors caused by the PE binding strip shaking;

[0045] The system is equipped with pneumatic scissors 2, whose housing is held by clamping member 13, and whose scissor head extends into the cutting protection box 15. The scissor head is pneumatically driven to perform the cutting action. The pneumatic scissors 2 provides powerful, fast, and stable cutting force, which greatly improves cutting efficiency compared to manual cutting (especially for batch or thicker PE edge banding strips) and reduces the labor intensity of the operator. In addition, under the joint constraint of clamping member 13 and cutting protection box 15, the scissor head of the pneumatic scissors 2 can accurately complete the cutting action in a fixed position. The pneumatic scissors 2 also has high reliability and durability, and is suitable for continuous operation in industrial environments.

[0046] The pneumatic scissors 5 can be connected to an external air source to perform cutting actions.

[0047] like Figures 1 to 7 As shown, in some embodiments of this utility model, the clamping member 13 includes two mounting plates 3 and multiple annular clamps 4. The two mounting plates 3 are arranged opposite to each other. One end of the mounting plate 3 is connected to the bottom support frame 11, and the other end of the mounting plate 3 is connected to the edge of the bottom of the cutting support plate 12.

[0048] The two ends of the annular clamp 4 are respectively located on the two mounting plates 3;

[0049] The annular clamp 4 is used to clamp or loosen the housing of the pneumatic scissors 2;

[0050] Specifically, the two mounting plates 3 are arranged opposite each other to form a stable support frame, that is, one end of which is fixedly installed to the bottom support frame 11 to provide a basic load-bearing point, and the other end is fixedly installed to the bottom edge of the cut support plate 12 to form a cantilever structure;

[0051] Multiple annular clamps 4 are arranged at intervals along the length of the mounting plate 3, and their two ends are fixed to the two mounting plates 3 by bolts or buckles, spanning the two mounting plates 3; the annular structure of the annular clamps 4 clamps the housing of the pneumatic scissors, achieving 360° circumferential fixation.

[0052] The annular clamp 4 has adjustable locking mechanisms (such as bolt tightening, lever locks, etc.) at both ends. By tightening the locking mechanism, the inner diameter of the annular clamp 4 shrinks, evenly pressing the housing of the pneumatic scissors 2. By loosening the locking mechanism, the inner diameter can be expanded, allowing the pneumatic scissors 2 to be removed or its position adjusted. The use of the annular clamp 4 enables quick assembly and disassembly, improving the maintenance convenience of the PE edge banding pneumatic cutting device.

[0053] like Figures 1 to 7 As shown, in some embodiments of this utility model, the annular clamp 4 includes two connecting clamp bodies 41, which are arranged opposite to each other and form an annular structure around each other.

[0054] The connecting hoop 41 includes a semi-circular connecting hoop 42 and connecting ears 43 located at both ends of the semi-circular connecting hoop 42;

[0055] Both connecting ears 43 are fixed to the two mounting plates 3 by bolt connection;

[0056] Specifically, threaded holes are provided on the connecting ear 43 and the mounting plate 3 at the corresponding positions of the connecting ear 43. A connecting bolt 31 is provided in the threaded hole on the mounting plate 3. The connecting bolt 31 passes through the threaded hole on the mounting plate 3 and the threaded hole on the connecting ear 43 in sequence, thereby fixing the connecting ear 43 to the mounting plate 3. More specifically, the installation process of the annular clamp 4 to the mounting plate 3 is as follows: the two connecting clamps 41 are placed opposite each other, and the annular structure formed therein is used to place the housing of the pneumatic scissors 2. Another connecting bolt 31 is inserted into the threaded hole on the connecting ear 43 and the mounting plate 3, and the two connecting clamps 41 are closed by the connecting bolt 31.

[0057] Specifically, the installation process is as follows: The two connecting clamps 41 are designated as connecting clamp #1 and connecting clamp #2, respectively; the two mounting plates 3 are designated as mounting plate #1 and mounting plate #2, respectively; the two connecting ears 43 on connecting clamp #1 are designated as connecting ear #1 and connecting ear #2, respectively; the two connecting ears 43 on connecting clamp #2 are designated as connecting ear #3 and connecting ear #4, respectively; the connecting ear #1 on connecting clamp #1 and the connecting ear #3 on connecting clamp #2 are positioned close to each other; the threaded holes on mounting plate #1 corresponding to connecting ear #1 and connecting ear #3 are marked as 1. # Threaded hole, the # 2 connecting lug on the # 1 connecting hoop is close to the # 4 connecting lug on the # 2 connecting hoop. The threaded hole on the # 2 mounting plate corresponding to the positions of the # 2 connecting lug and the # 4 connecting lug is marked as the # 2 threaded hole. Align the threaded hole on the # 1 connecting lug, the threaded hole on the # 3 connecting lug and the # 1 threaded hole, and insert one of the connecting bolts 31. Align the threaded hole on the # 2 connecting lug, the threaded hole on the # 4 connecting lug and the # 2 threaded hole, and insert the other connecting bolt 31. Through the connecting bolts 31, the two connecting hoops 41 are closed to form a complete ring constraint.

[0058] This split-type ring clamp design enables the locking function of a semi-circular connecting clamp with double bolt connecting ears.

[0059] like Figures 1 to 7 As shown, in some embodiments of this utility model, the inner surface of the connecting hoop 41 is a friction surface; it has good anti-slip reliability, that is, when the pneumatic scissors 2 is working, it is easy to generate recoil force or shaking. Traditional smooth hoops require a large locking force to prevent slippage, which can easily lead to locking failure and the pneumatic scissors 2 slipping off. The inner surface of the connecting hoop 41 is set as a friction surface, which can effectively reduce vibration acceleration and prevent the pneumatic scissors 2 from falling off instantly.

[0060] like Figures 1 to 7 As shown, in some embodiments of this utility model, both ends of the mounting plate 3 are fixed to the bottom support frame 11 and the cutting support plate 12 respectively by welding connection.

[0061] The two ends of the mounting plate 3 are fixedly installed on the bottom support frame 11 and the cutting support plate 12, forming a stable support for the multiple ring clamps 4 and the pneumatic scissors 2 installed in the ring clamps 4.

[0062] like Figures 1 to 7 As shown, in some embodiments of this utility model, the number of annular clamps 4 is not less than 2;

[0063] Since multiple annular clamps 4 are arranged at intervals along the length of the mounting plate 3, a more stable constraint can be formed on the pneumatic shears 2 therein.

[0064] like Figures 1 to 7 As shown, in some embodiments of this utility model, the material of the cutting protective box 15 is transparent.

[0065] The cutting protective box 15 is made transparent, which makes it easy to observe the installation position of the pneumatic scissors 2 inside, as well as the cutting position of the PE edge banding strip. This makes it easier to adjust the installation position of the pneumatic scissors 2 and the cutting position of the PE edge banding strip, making it suitable for practical use.

[0066] like Figures 1 to 7 As shown, in some embodiments of this utility model, the PE edge banding pneumatic cutting device further includes a foot valve 5 and an air pipe 6. The foot valve 5 is connected to the pneumatic scissors 2 through the air pipe 6, and the foot valve 5 is used to connect to an external air source.

[0067] In this setup, the air inlet of the foot valve 5 is connected to an external compressed air source via an air pipe 6, and the air outlet of the foot valve 5 is connected to the drive interface of the pneumatic scissors 2 via the air pipe 6.

[0068] In actual operation, ensure that the external air pressure meets the working requirements of the pneumatic scissors 2. Pass the PE edge banding strip to be cut through the edge banding strip receiving groove 16 and through the opening area of ​​the scissor head of the pneumatic scissors 2. Press down on the foot pedal 5 to trigger the air circuit to open. Compressed air drives the piston of the pneumatic scissors 2 through the air pipe 6, causing the scissor head of the pneumatic scissors 2 to close instantly and cut the PE edge banding strip. Release the foot pedal 5, the air circuit will close, and the scissor head of the pneumatic scissors 2 will automatically reset and open. Take out the cut PE edge banding strip and prepare for the next operation.

[0069] Equipped with a foot pedal valve 5, the operator can directly press the foot pedal valve 5 to complete the cutting after threading the PE edge banding strip, reducing the time required for a single action and significantly improving continuous cutting efficiency. Pneumatic drive replaces manual force, avoiding operator hand fatigue or strain. In addition, the operator's hands do not need to touch the cutting equipment, avoiding the risk of scratches. Moreover, the pneumatic scissors 2 close instantly, ensuring a clean and burr-free cut, guaranteeing the cutting quality of the PE edge banding strip. This structure is simple, has a low failure rate, and is suitable for high-frequency cutting scenarios of PE edge banding strips, effectively improving the cutting efficiency of PE edge banding strips.

[0070] like Figures 1 to 7 As shown, in some embodiments of this utility model, the cutting and protective box 15 is fixed in the mounting groove 14 by bolt connection and / or welding connection.

[0071] The protective box 15 can be fixed in the mounting groove 14 by bolt connection, welding connection, or a combination of bolt connection and welding connection to improve its assembly stability.

[0072] like Figures 1 to 7 As shown, in some embodiments of this utility model, the top of the cutting and protective box 15 is provided with a protective cover;

[0073] This protective cover effectively protects the cutting process and prevents cutting waste from splashing.

[0074] This utility model provides a pneumatic cutting device for PE edge banding strips. Through the design of pneumatic scissors 2 and a cutting protective box 15, the pneumatic scissors 1 are used to cut the PE edge banding strips located in the edge banding strip receiving groove 16 on the cutting protective box 15. The cutting protective box 15 forms a cutting cavity, housing the scissor head of the pneumatic scissors 2 within this cavity, avoiding the risk of exposure of the scissor head and fundamentally eliminating the inherent risk of cuts from the blade. Furthermore, when using the pneumatic scissors 2 to cut the PE edge banding strips, the pneumatic scissors 2 are clamped and fixed by the clamping member 13 on the bottom support frame 11, providing stable support for the pneumatic scissors 2 and preventing blade vibration during cutting. This ensures a smooth and even cut surface of the PE edge banding strip, thereby improving product quality.

[0075] With this pneumatic cutting device, the pneumatic scissors 2 are clamped and fixed by the clamping member 13 on the bottom support frame 11, which provides stable support for the pneumatic scissors 2. Therefore, in the actual cutting process, the operator's hands can be freed, eliminating muscle fatigue caused by continuous manual force application. Moreover, the use of this pneumatic cutting device can significantly reduce the single cutting time and effectively improve cutting efficiency.
