Description

Technical Field

[0001] This utility model relates to the field of carpet production and processing technology, and in particular to a carpet edge cutting device with a waste recycling structure. Background Technology

[0002] After production, carpets often have excess edges at the four corners, such as rough edges or irregular parts. At this time, it is necessary to use an edge trimming device to remove these edges, making the edges neat and smooth, eliminating burrs, loose fibers or uneven parts of the carpet edges, and making the finished product more beautiful.

[0003] Most current carpet trimming devices have relatively simple structures. During trimming, they generate a large amount of fiber and fluff debris. These debris are lightweight and will scatter everywhere, resulting in waste materials scattered all over the device after trimming, polluting the working environment and increasing the difficulty of subsequent cleaning.

[0004] Therefore, in response to the issue that existing carpet trimming devices produce debris that scatters everywhere, a carpet trimming device with a waste recycling structure can be designed. By using negative pressure suction, the waste generated during the trimming operation can be collected in a unified manner, preventing the debris from scattering and polluting the working environment, reducing the difficulty of subsequent cleaning operations, ensuring a clean and tidy working space, and thus effectively enhancing the practical value of the device. Utility Model Content

[0005] To overcome the problem that most carpet trimming devices generate a large amount of fiber and fluff debris during trimming, which is lightweight and will scatter everywhere, polluting the working environment and increasing the difficulty of subsequent cleaning, this utility model is proposed.

An air pump is provided on the outer side of the negative pressure pipe. A branch pipe is connected to the top of the negative pressure pipe. A protective cover is provided at the bottom of the fixed block.

[0007] Preferably, the carpet to be processed is laid flat in the center of the processing table. The bidirectional lead screw is rotated to move the U-shaped support frame, which supports the fixed plate. The fixed plate is moved above the edge of the carpet to be cut. The position of the adjusting lead screw is fixed by the fixed plate. Rotating the adjusting lead screw moves the fixed plate, causing the cutting blade to move from one end of the carpet edge to the other. The cutting blade cuts the carpet edge. Simultaneously, a protective cover is placed over the cutting edge. The waste bin is placed in the fixed frame. The air pump is started to control the negative pressure pipe to generate negative pressure, thus simultaneously generating negative pressure inside the branch pipe. The protective cover is controlled by the branch pipe to suck up the debris generated during cutting. The debris enters the waste bin through the branch pipe and the negative pressure pipe for unified collection. This achieves unified collection of waste generated during cutting, preventing debris from scattering and polluting the working environment, reducing the difficulty of subsequent cleaning, ensuring a clean and tidy working space, and enhancing the practical value of the device.

[0008] Preferably, the bidirectional lead screw is rotatably connected to the processing table, the adjusting lead screw is threadedly connected to the fixed plate, the fixed block is threadedly connected to the adjusting lead screw, the waste bin is fitted into the groove inside the fixed frame, the negative pressure pipe is connected through the inside of the fixed frame, two sets of branch pipes are symmetrically arranged, the other end of the branch pipe is connected through the protective cover, and the cutting blade is located inside the protective cover.

[0009] Preferably, a control panel is provided on the outer side of one end of the processing table, and the air pump is electrically connected to the control panel. A servo motor is provided on the outer side of one end of the processing table, and the servo motor is electrically connected to the control panel.

One end of the U-shaped support frame is threadedly connected to the bidirectional lead screw, and the other end of the U-shaped support frame is slidably connected to the guide rod.

[0010] Preferably, two sets of first hydraulic rods are symmetrically arranged at both ends of the bottom surface of the fixed plate. The first hydraulic rods are electrically connected to the control panel. A first pressure plate is provided at the outer telescopic end of the first hydraulic rod. The cutting blade is set close to one side of the first pressure plate. A storage groove is opened in the middle of the bottom end of the first pressure plate. An adjusting screw is threaded through the middle of the first pressure plate. A second pressure plate is provided at the bottom end of the adjusting screw. The second pressure plate is fitted and connected to the storage groove.

[0011] Preferably, a first motor is provided at one end of the outer side of the fixed plate. The first motor is electrically connected to the control panel, and the output end of the first motor is connected to the adjusting screw.

[0012] Preferably, a second hydraulic rod is provided at the bottom of the fixing block, the second hydraulic rod is electrically connected to the control panel, a connecting block is provided at the outer telescopic end of the second hydraulic rod, the cutting blade is provided at one end of the connecting block, the cutting blade is rotatably connected to the connecting block, a second motor is provided at the other end of the connecting block, the second motor is electrically connected to the control panel, and the output end of the second motor is connected to the drive shaft of the cutting blade.

[0013] Preferably, the waste bin is equipped with a handle at the front end, and baffles are symmetrically arranged at the four corners of the front end of the fixed frame, with the baffles rotatably connected to the fixed frame.

[0014] The beneficial effects of this utility model are:

[0015] During edge trimming, the carpet to be processed is laid flat in the center of the processing table. Rotating the bidirectional screw drives the U-shaped support frame to move, and moving the U-shaped support frame moves the fixed plate above the edge of the carpet to be cut. Rotating the adjusting screw drives the fixed block to move, and moving the fixed block moves the cutting blade from one end of the carpet edge to the other. The cutting blade cuts the carpet edge. At the same time, a protective cover is placed over the cutting blade's cutting position. The waste bin is placed in the fixed frame, and the air pump is started to control the negative pressure pipe to generate negative pressure, thereby generating negative pressure inside the branch pipe. The protective cover is controlled by the branch pipe to suck up the debris generated during edge trimming. The debris enters the waste bin through the branch pipe and the negative pressure pipe for unified collection. This solves the problem that most carpet edge trimming devices generate a large amount of fiber and fluff debris during edge trimming. These debris are light and will scatter everywhere, causing waste to be scattered all over the device after edge trimming, polluting the working environment and increasing the difficulty of subsequent cleaning. This enhances the practical value of the device. Attached Figure Description

The extension and retraction of the second hydraulic rod 701 adjusts the height of the connecting block 702. The cutting blade 7 is connected to the connecting block 702 by rotation. The second motor 703 is controlled by the control panel 201 to drive the cutting blade 7 to rotate, thereby flexibly adjusting the placement height of the cutting blade 7 and ensuring that the cutting blade 7 can carry out cutting operations normally. The front end of the waste bin 9 is provided with a handle 901, and the four corners of the front end of the fixed frame 8 are symmetrically provided with baffles 902. The baffles 902 are rotatably connected to the fixed frame 8. The waste bin 9 can be flexibly picked up and put in by the handle 901. After the waste bin 9 is placed in the fixed frame 8, the baffles 902 are rotated in sequence so that the baffles 902 abut against the four corners of the waste bin 9 and fix the waste bin 9 in the fixed frame 8.

[0027] Before the edge trimming operation, the carpet to be processed is laid flat in the center of the processing table 1. The control panel 201 sends the running command to the servo motor 202.
