Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to an edge trimming device after the weaving of a blanket. Background Technology

[0002] Blanket weaving is a traditional craft with a long history. With the development of industrialization, blanket production has gradually shifted from hand weaving to mechanization and automation, greatly improving production scale and efficiency. However, the requirements for the quality and appearance of blankets have also become increasingly stringent. The edge quality of a blanket directly affects its overall aesthetics, durability, and user experience. Modern consumers have higher and higher requirements for the quality and appearance of blankets. They not only want blankets to be soft, comfortable, and warm, but also require blankets to have neat, smooth, and flawless edges.

[0003] When trimming the edges of knitted fabric, it is necessary to position the knitted fabric. Knitted fabric is relatively soft, and the contact area between the pressing structure and the knitted fabric is limited, making it difficult to press and fix. Furthermore, when trimming the edges of knitted fabric, only sanding is used, which can easily leave small untreated burrs. The trimming range is limited, which affects the trimming effect. Therefore, in order to address the above problems, an edge trimming device for knitted fabric that is easy to position is proposed.

[0004] The existing patent (publication number: CN213295823U) discloses an edge trimming device for knitted fabric that is easy to position. It facilitates the placement of the knitted fabric through adjusting blocks and guide plates. The guide plates can adjust the contact area with the knitted fabric. The pressure rod and fixing plate facilitate the positioning of the knitted fabric. The limiting block can adjust the position of the slider and trimming plate to facilitate the contact between the trimming plate and the knitted fabric. The abrasive disc facilitates the abrasion of the knitted fabric edge. The side plate and heating plate facilitate the heating of the knitted fabric to remove burrs. The first motor and threaded rod facilitate the movement of the connecting plate and expand the range of knitted fabric trimming.

[0005] To address the aforementioned issues, existing patents offer solutions. Existing edge trimming devices for yarn blankets typically employ fixed limiting devices, which are not suitable for adapting to the trimming needs of yarn blankets of different specifications. This can lead to positional shifts in yarn blankets of different specifications during transport, affecting the quality of subsequent edge trimming. Furthermore, it is not convenient to automatically adjust the trimming range according to the width of the yarn blanket, thus impacting production efficiency.

[0006] To address this, a device for edge trimming after blanket weaving is proposed. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A blanket weaving edge trimming device includes a base 1, a processing chamber 2 fixedly connected to the top of the base 1, a limit component 4 provided on the left side of the processing chamber 2, and a trimming component 5 provided on the right side of the processing chamber 2.

[0030] The limiting component 4 includes an adjusting hydraulic cylinder 401 bolted to the top of the processing chamber 2. The output end of the adjusting hydraulic cylinder 401 is fixedly connected to a top plate 402. A groove 403 is provided inside the top plate 402. A dual-axis hydraulic cylinder 404 is bolted inside the groove 403. Moving blocks 405 are fixedly connected to both sides of the dual-axis hydraulic cylinder 404. A limiting frame 406 is fixedly connected to the bottom of the moving blocks 405. A limiting rod 407 is rotatably connected inside the limiting frame 406.

[0031] In this embodiment: by activating the adjusting hydraulic cylinder 401, the output end of the adjusting hydraulic cylinder 401 extends and drives the top plate 402 to move slowly downward until the top plate 402 reaches a height that matches the thickness of the blanket. Then, the dual-axis hydraulic cylinder 404 inside the groove 403 is activated. The output ends on both sides of the dual-axis hydraulic cylinder 404 push the moving blocks 405 connected to them to move outward. When the moving blocks 405 move, they also drive the bottom fixedly connected limiting frames 406 to move together until the distance between the limiting frames 406 matches the width of the blanket. When the blanket reaches the position of the limiting frames 406, the limiting rods 407 on the inner side of the limiting frames 406 will gently press against the sides of the blanket. The limiting rods 407 are rotatably connected to the limiting frames 406. As the blanket is transported, the limiting rods 407 will rotate synchronously under the drive of the blanket to limit the blanket during the transportation process, ensuring that the blanket always stays in the correct position and does not deviate.

[0032] Specifically, such as Figure 3 As shown, the trimming assembly 5 includes a lifting hydraulic cylinder 501 bolted to the top of the processing chamber 2, and an adjusting frame 502 is fixedly connected to the bottom of the lifting hydraulic cylinder 501.

[0033] Specifically, such as Figure 3As shown, a servo motor 503 is bolted to the outside of the adjustment frame 502, and a dual-axis lead screw 504 is fixedly connected to the output end of the servo motor 503. A connecting block 505 is threaded to the outside of the dual-axis lead screw 504.

[0034] Specifically, such as Figure 3 As shown, a motor body 506 is bolted inside the connecting block 505, and a rotating shaft 507 is rotatably connected to both sides of the bottom of the connecting block 505. The output end of the motor body 506 is fixedly connected to the right rotating shaft 507, and a grinding belt 508 is sleeved on the outside of the rotating shaft 507.

[0035] In this embodiment: when the yarn blanket is conveyed to the bottom of the trimming assembly 5, the lifting hydraulic cylinder 501 is activated, and then its output end extends downward to drive the adjusting frame 502 to gradually move downward. When the adjusting frame 502 descends to a suitable height to ensure that the subsequent grinding belt 508 can fully contact the edge of the yarn blanket and apply appropriate pressure, the servo motor 503 on the outside of the adjusting frame 502 is activated. Then, while the servo motor 503 is running, it drives the dual-axis lead screw 504 at its output end to rotate. Under the rotation of the dual-axis lead screw 504, the connecting block 505, which is threaded to its outside, will move horizontally along the lead screw according to the rotation direction of the lead screw. During the movement of 505, the grinding belt 508 at the bottom moves together until the grinding belt 508 is accurately positioned at the two edges of the blanket to be repaired. Then, the motor body 506 inside the connecting block 505 is started. The output end of the motor body 506 drives the right rotating shaft 507 to rotate at high speed. Then, the right rotating shaft 507 drives the left rotating shaft 507 to rotate synchronously through transmission. When the rotating shaft 507 rotates, the grinding belt 508 on its outer side starts to rotate at high speed. Then, the grinding belt 508 makes full contact with the edge of the blanket, and grinds and repairs the rough edges and uneven parts of the blanket edge to make the blanket edge neat and smooth.

[0036] Specifically, such as Figure 2 As shown, a negative pressure vacuum cleaner 6 is bolted to the top of the processing chamber 2, and a vacuum hood 7 is bolted to the top side inside the processing chamber 2. The output end of the negative pressure vacuum cleaner 6 is connected to the vacuum hood 7. A collection box 8 is bolted to the top of the processing chamber 2, and the collection box 8 is located to the right of the negative pressure vacuum cleaner 6.

[0037] Specifically, such as Figure 5 , Figure 6 As shown, a collection frame 9 is fixedly connected to the bottom of the base 1, a collection box 10 is slidably connected inside the collection frame 9, a pull rod 11 is fixedly connected to the outside of the collection box 10, a drive motor 12 is fixedly connected to the outside of the collection frame 9, and a dust cleaning brush 13 is fixedly connected to the output end of the drive motor 12.

[0038] In this embodiment: by setting up a negative pressure vacuum cleaner 6, a dust hood 7, and a collection box 8, when the edge trimming device after starting the blanket weaving process is trimming the edge of the blanket, the negative pressure vacuum cleaner 6 at the top of the processing chamber 2 is turned on. The vacuum cleaner 6 then generates suction, and through the pipe connected to the dust hood 7, sucks in the lint, debris, and other impurities generated during the trimming process in the processing chamber 2. These impurities are then collected in the collection box 8 located to the right of the negative pressure vacuum cleaner 6, thus cleaning and collecting the debris in the processing chamber 2. This facilitates timely cleaning of the debris generated during the trimming process, preventing debris from flying and causing secondary pollution to the blanket, and ensuring the cleanliness and quality of the blanket. The device is constructed by setting up a collection frame 9, a collection box 10, a pull rod 11, a drive motor 12, and a cleaning brush 13. During operation, the drive motor 12 on the outside of the collection frame 9 is started, and its output end drives the cleaning brush 13 to rotate continuously. As the cleaning brush 13 rotates, it contacts the surface of the conveyor belt 14 and sweeps off the debris attached to the surface of the conveyor belt 14. The swept debris then falls into the collection box 10 inside the collection frame 9. When the collection box 10 needs to be cleaned, the operator pulls the pull rod 11 on the outside of the collection box 10 to pull the collection box 10 out of the collection frame 9, emptys the debris, and then pushes it back into place.

[0039] Specifically, such as Figure 1 , Figure 6 As shown, a conveyor belt 14 is bolted inside the base 1, a laser rangefinder 15 is bolted to the top of the processing chamber 2, and a control panel 3 is bolted to the outside of the base 1.

[0040] Specifically, such as Figure 1 As shown, a support leg 16 is fixedly connected to the bottom of the base 1, and a rubber pad 17 is bolted to the bottom of the support leg 16.

[0041] In this embodiment: by setting up a conveyor belt 14, a laser rangefinder 15, and a control panel 3, the conveyor belt 14 realizes the automatic transport of the yarn blanket to improve the efficiency of the trimming work. At the same time, the laser rangefinder 15 acquires yarn blanket data in real time, providing a basis for the automated control of the device, making the limit and trimming operations more precise and improving the quality of yarn blanket edge trimming. The control panel 3 facilitates the operator's control of the device, enhancing the operability and ease of use of the device. By setting up support legs 16 and rubber pads 17, the rubber pads 17 increase the friction between the device and the ground, ensuring the stability of the device during operation and avoiding problems such as decreased yarn blanket trimming accuracy due to vibration.

[0042] Working Principle: During the edge trimming process after blanket weaving, the blanket to be trimmed is first placed on the conveyor belt 14 inside the base 1. Then, the conveyor belt 14 is started via the control panel 3. The conveyor belt 14 then rotates at a constant speed to smoothly transport the blanket into the processing chamber 2. At this time, the laser rangefinder 15 on the top of the processing chamber 2 measures the blanket to be trimmed to obtain data such as the thickness and width of the blanket, and transmits this data to the control system. After receiving the data, the control system performs rapid analysis and processing, and sends a command to the adjusting hydraulic cylinder 401 based on the height and width information of the blanket. Then, the adjusting hydraulic cylinder 401 is started, and the output end of the adjusting hydraulic cylinder 401 extends, driving the top plate 402 to move slowly downwards until the top plate... When the blanket reaches a height that matches the thickness of the blanket, the dual-axis hydraulic cylinder 404 inside the groove 403 is activated. The output ends on both sides of the dual-axis hydraulic cylinder 404 then push the connected moving blocks 405 outwards. As the moving blocks 405 move, they also move the bottom-fixed limiting frames 406 together until the distance between the limiting frames 406 matches the width of the blanket. When the blanket reaches the position of the limiting frames 406, the limiting rods 407 inside the limiting frames 406 gently press against both sides of the blanket. The limiting rods 407 are rotatably connected to the limiting frames 406. As the blanket is transported, the limiting rods 407 rotate synchronously under the influence of the blanket, thus limiting the blanket during transport and ensuring that the blanket remains in place. Maintaining the correct position without deviation, when the yarn blanket is conveyed to the bottom of the dressing assembly 5, the control system activates the lifting hydraulic cylinder 501 based on the previously acquired yarn blanket data. Its output end then extends downwards, driving the adjusting frame 502 to gradually move downwards. When the adjusting frame 502 descends to a suitable height to ensure that the subsequent grinding belt 508 can fully contact the edge of the yarn blanket and apply appropriate pressure, the servo motor 503 on the outside of the adjusting frame 502 is activated. Simultaneously, the servo motor 503 drives the dual-axis lead screw 504 at its output end to rotate. As the dual-axis lead screw 504 rotates, the connecting block 505, threaded to its outer side, moves horizontally along the lead screw according to the rotation direction. During the movement of the connecting block 505, the belt... The bottom polishing belt 508 moves together with the carpet until it is accurately positioned at the two edges of the carpet to be repaired. Then, the motor body 506 inside the connecting block 505 is started. The output end of the motor body 506 drives the right rotating shaft 507 to rotate at high speed. Then, the right rotating shaft 507 drives the left rotating shaft 507 to rotate synchronously through transmission. When the rotating shaft 507 rotates, the polishing belt 508 on its outer side starts to rotate at high speed. Then, the polishing belt 508 makes full contact with the edge of the carpet, polishing and repairing the rough edges and uneven parts of the carpet edge to make the carpet edge neat and smooth. During the process of polishing the carpet edge, a large amount of lint, debris and other impurities will be generated. Then, the negative pressure vacuum cleaner 6 is started.Next, the negative pressure vacuum cleaner 6 generates strong suction, drawing in the air below the vacuum hood 7 along with the lint and debris generated during polishing through a pipe connected to the hood 7. The sucked-in impurities then enter the negative pressure vacuum cleaner 6 through the pipe, undergo preliminary filtration, and are collected in a collection box 8 connected to the exhaust port of the negative pressure vacuum cleaner 6 to prevent secondary contamination of the finished carpet.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
