Description

Technical Field

[0001] This utility model relates to the field of carpet edging technology, and in particular to a carpet edging traction device. Background Technology

[0002] In the carpet manufacturing process, the edge binding process is a key post-processing step. Its quality directly affects the product's aesthetics, durability, and market value. A fine edge binding process can effectively prevent problems such as fraying and pilling at the carpet edges. At the same time, exquisite edge binding can enhance the product's perceived quality, allowing the carpet to stand out in the fierce market competition.

[0003] Traditional edge binding devices typically consist of a fixed workbench and an edge binding mechanism, but they generally suffer from low automation and inconvenient operation. The edge binding devices commonly found on the market currently have the following technical defects: (1) They lack an effective traction mechanism. In actual operation, part of the carpet is placed on the edge binding device, while the other part hangs down or is draped on the workbench. Since carpet products are usually large in size and have a certain weight, it is often necessary to assign 1-2 additional workers to pull the edge binding device from the front. This not only significantly increases labor costs, but also makes it easy for production efficiency to decrease due to improper coordination during multi-person collaboration. (2) There is a problem of insufficient positioning accuracy. Due to the lack of an automated traction positioning system, the carpet often shifts position during the edge binding process. When workers manually adjust, it is difficult to ensure the consistency of positioning each time, resulting in unstable edge binding quality and reduced product qualification rate. Especially when dealing with long carpets, the weight of the carpet will exacerbate the position shift and seriously affect the edge binding accuracy. (3) The operation is not convenient. The traditional edge binding process requires workers to repeatedly bend over to pull and adjust the position of the carpet, which is labor-intensive and inefficient. At the same time, the frictional resistance between the carpet and the workbench will affect the smoothness of operation and further increase the difficulty of operation.

[0004] Therefore, given the lack of an effective traction mechanism in existing edging devices, carpets often shift position during the edging process, requiring workers to repeatedly pull and drag them, which is inconvenient. A carpet edging traction device can be designed to achieve precise positioning and transport of the carpet through an automatic traction mechanism, solving the shifting problem caused by manual operation and making the edging operation more accurate and efficient. Utility Model Content

[0005] To overcome the problem that existing edging devices lack an effective traction mechanism, carpets often shift position during the edging process, requiring workers to pull them repeatedly, which is inconvenient.

[0006] The technical solution of this utility model is as follows: a carpet edging traction device, including a frame, an active traction roller rotatably connected between two vertical end plates of the frame, a driven traction roller that can be vertically raised and lowered above the active traction roller, a photoelectric switch and a finger cylinder, a photoelectric switch installed on the upper surface of the bottom plate at the inlet end of the frame, the photoelectric switch is used to detect the entry of carpet and is connected to an external controller signal, when the photoelectric switch detects carpet, the controller controls the lifting component to lower the driven traction roller to press the carpet, and at the same time controls the power device to drive the active traction roller to rotate to achieve traction, a side plate is fixedly extended along the carpet outlet direction of the vertical end plate of the frame, a supporting component is installed on the inner wall of the side plate, and a finger cylinder is rotatably connected between the two sets of side plates to transfer the traction completed carpet to the upper surface of the supporting component.

[0007] Preferably, the frame is installed in front of the carpet binding device, with the upper surface of the active traction roller flush with the upper surface of the active traction roller. When the binding device is working, the carpet moves forward. When the photoelectric switch detects that the front end of the carpet has reached the set position, it transmits a signal to the external controller. The controller then issues a command: to make the driven traction roller descend smoothly and press the carpet, and at the same time, to start the power unit to drive the active traction roller to rotate, using the friction of the roller surface to pull the carpet forward. The carpet is inserted into the finger cylinder. After the finger cylinder senses the carpet, it clamps the front end of the carpet and controls the rotation of the finger cylinder to make the carpet fall on the surface of the supporting component. When the binding is completed, the finger cylinder is released, and the operator sits at the work station of the binding device to pull the carpet back. Then the binding operation is performed on the other edges of the carpet. At the same time, the finger cylinder returns to the initial position for easy operation.

[0008] Preferably, the supporting component includes several rollers arranged at equal intervals along the carpet conveying direction to form a continuous and uniform support structure, with both ends of the rollers fixed to the side plate by bearing seats.

[0009] Preferably, the supporting component is a tray, which has an L-shaped bent structure, including a horizontally arranged bearing part and an outwardly inclined extension part, with the two parts smoothly transitioning through a rounded corner.

[0010] Preferably, the working surface of the pallet is fitted with balls arranged in a matrix, and each ball is rotatably mounted in the positioning hole of the pallet through a cage structure to form a low-friction support surface.

[0011] Preferably, the upper surface of the pallet is provided with several evenly distributed air outlets, and the inside of the pallet is provided with an airflow cavity communicating with each air outlet. The cavity is connected to an external compressed air supply device through a pneumatic connector provided on the side of the pallet.

[0012] Preferably, a rotating shaft is rotatably mounted between the side plates, and a finger cylinder is fixedly connected to the middle of the rotating shaft via an extension column. A motor is provided on the outer side of the side plates, and the output shaft of the motor is connected to the rotating shaft via a coupling.

[0013] Preferably, lifting cylinders are installed on the upper surface of the vertical end plates on both sides of the frame. The piston rod of the lifting cylinder extends downward and passes through the top of the vertical end plate, and the end is connected to a slider. The slider is fitted with an upper bearing. The two ends of the driven traction roller are respectively installed in the upper bearings on both sides. The inner wall of the hollow part in the middle of the vertical end plate of the frame is provided with a vertical slide rail, and the slider and the slide rail form a sliding pair.

[0014] Preferably, lower bearings are embedded in the inner side of the vertical end plates on both sides of the frame, and the two ends of the active traction roller are installed in the lower bearings. At least two support columns are fixedly connected between the vertical end plates on both sides of the frame, and the upper surface of the support columns is flush with the bearing surface of the supporting component.

[0015] The beneficial effects of this utility model are as follows: By cooperating with the photoelectric switch and the control system, automatic detection of carpet feeding and intelligent control of the traction process are realized. When the photoelectric switch detects the carpet, the system automatically completes the pressing down of the driven traction roller and the driving of the active traction roller, completely replacing the traditional manual pulling operation. This automated design not only reduces labor intensity but also ensures the consistency and reliability of the traction process. The use of a double-roller traction structure ensures the straightness and stability of the carpet during the conveying process. Compared with manual operation, this device can control the positional deviation of the carpet within ±1mm, significantly improving the processing accuracy of the edge binding process. The integrated traction function allows a single worker to complete the entire edge binding process, greatly improving edge binding efficiency while reducing the need for manual labor. The supporting components play a guiding role, making the carpet pull-back operation simpler and more labor-saving. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Example 1

[0027] Please see Figures 1-4 This utility model provides an embodiment of a carpet edging and traction device, including a frame 1, an active traction roller 2 rotatably connected between two vertical end plates of the frame 1, a driven traction roller 3 that can be vertically raised and lowered above the active traction roller 2, a photoelectric switch 4 and a finger cylinder 8, a photoelectric switch 4 installed on the upper surface of the bottom plate at the inlet end of the frame 1, the photoelectric switch 4 is used to detect the entry of carpet and is connected to an external controller signal, when the photoelectric switch 4 detects carpet, the controller controls the lifting component to lower the driven traction roller 3 to press the carpet, and at the same time controls the power device to drive the active traction roller 2 to rotate to achieve traction, a side plate 5 is fixedly extended from the vertical end plate of the frame 1 along the carpet outlet direction, a support component is installed on the inner wall of the side plate 5, and a finger cylinder 8 is rotatably connected between the two sets of side plates 5 to transfer the traction completed carpet to the upper surface of the support component.

[0028] The supporting component includes several rollers 6 arranged at equal intervals along the carpet conveying direction to form a continuous and uniform support structure. The two ends of the rollers 6 are fixed to the side plates 5 through bearing seats. A rotating shaft 9 is rotatably installed between the side plates 5. The middle of the rotating shaft 9 is fixedly connected to the finger cylinder 8 through the extension column 10. A motor 11 is provided on the outside of the side plates 5. The output shaft of the motor 11 is connected to the rotating shaft 9 through a coupling.

[0029] Meanwhile, lifting cylinders 12 are installed on the upper surface of the vertical end plates on both sides of the frame 1. The piston rod of the lifting cylinder 12 extends downward and passes through the top of the vertical end plate, and the end is connected to a slider 13. The slider 13 is fitted with an upper bearing 14. The two ends of the driven traction roller 3 are respectively installed in the upper bearings 14 on both sides. The inner wall of the hollow part in the middle of the vertical end plate of the frame 1 is provided with a vertical slide rail 15. The slider 13 and the slide rail 15 form a sliding pair.

[0030] In addition, lower bearings 16 are embedded in the inner side of the vertical end plates on both sides of the frame 1, and the two ends of the active traction roller 2 are installed in the lower bearings 16. At least two support columns 17 are fixedly connected between the vertical end plates on both sides of the frame 1, and the upper surface of the support column 17 is flush with the bearing surface of the supporting component.

[0031] Working principle: The frame 1 is installed in front of the carpet binding device. The upper surface of the active traction roller 2 is flush with the upper surface of the active traction roller 2. When the binding device is working, the carpet moves forward. When the photoelectric switch 4 detects that the front end of the carpet has reached the set position, it transmits a signal to the external controller. The controller then issues a command: on the one hand, it controls the lifting cylinder 12 to move, driving the slider 13 to move down along the slide rail 15, so that the driven traction roller 3 descends smoothly through the guide of the upper bearing 14 to press the carpet. On the other hand, it starts the power unit to drive the active traction roller 2 to rotate, using the friction of the roller surface to pull the carpet. The carpet is guided forward and inserted into the finger cylinder 8. After the finger cylinder 8 senses the carpet, it clamps the front end of the carpet. Then, the motor 11 is started, which drives the carpet to rotate through the rotating shaft 9. The finger cylinder 8 rotates 270°, causing the carpet to fall onto the surface of the supporting component. The motor 11 stops. After the edging is completed, the finger cylinder 8 is released. The worker sits at the edging device station and pulls the carpet back from above the roller 6 and support column 17. Then, the other edges of the carpet are edged. At the same time, the motor 11 starts and continues to rotate 90°, returning to the initial position for the next operation.
