Description

Technical Field

[0001] The present invention belongs to the technical field of trimming devices, and more specifically, relates to a laser trimming device and a trimming method for coated Oxford cloth. Background Art

[0002] Oxford cloth, also known as Oxford spin, is usually woven by interlacing cotton yarn and polyester fiber. It is a fabric with diverse functions and wide applications. Due to its excellent abrasion resistance, breathability, wrinkle resistance, and the additional characteristics that can be imparted after coating treatment, it is widely used in multiple fields such as outdoor sports, home decoration, transportation, and engineering construction.

[0003] Generally, after the production of Oxford cloth, the coating material is evenly applied to the Oxford cloth using a scraper or a roller according to the product's use. Then, the coating material is cured by natural evaporation or baking to form a thin film, thereby imparting different characteristics to the Oxford cloth. Subsequently, the coated Oxford cloth is trimmed to ensure that the required size and shape requirements can be met when leaving the factory. Currently, the existing trimming method generally involves laying the Oxford cloth flat on a conveyor belt and trimming the Oxford cloth through a laser cutting device under the transportation of the conveyor belt. However, during the cutting process, the movement of the Oxford cloth only follows the conveyor belt by the friction force between the Oxford cloth and the conveyor belt, lacking the fixation and clamping of the Oxford cloth itself, resulting in the Oxford cloth being easily affected by the external environment and moving during the trimming process, ultimately leading to the trimming not meeting the factory standards. Based on this, a laser trimming device for coated Oxford cloth is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a laser trimming device that can overcome or at least partially solve the above problems.

[0012] Further, the guiding rod is arranged above the clamping assembly. When the clamping assembly moves along the first guiding groove to the lower part of the guiding rod, the clamping assembly drives the guiding rod to move upward to release the clamping and flattening of the coated Oxford cloth by the upper pressing rod.

[0013] Preferably, a servo motor is fixedly connected to the support table, and the output end of the servo motor is fixedly connected to the rotating shaft.

Detailed implementation mode

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0037] Embodiment 1: Refer to Figures 1-6 , a laser edge cutting device for coated Oxford cloth, including a support table 1, further including: a longitudinal slide rail 11 is fixedly connected to the support table 1, a transverse slide rail 12 is slidably connected to the longitudinal slide rail 11, and a laser cutting head 13 is slidably connected to the transverse slide rail 12; a guiding block 63 is fixedly connected to the support table 1, and a first guiding groove 6 is formed by combining the guiding block 63 and the support table 1, and a second guiding groove 61 is formed on the guiding block 63; a plurality of clamping components 4 are slidably connected to the first guiding groove 6 and the second guiding groove 61, and the clamping components 4 are used to clamp the coated Oxford cloth. When the clamping components 4 are located on both sides of the first guiding groove 6, the clamping components 4 open, and when the clamping components 4 are located in the middle of the first guiding groove 6, the clamping components 4 close and clamp; rotating shafts 21 are rotatably connected to both sides of the support table 1 and the guiding block 63, a first pulley 211 and a second pulley 212 are respectively fixedly connected to the rotating shafts 21, a second conveyor belt 23 is sleeved on the two second pulleys 212, and the second conveyor belt 23 is used to transport the coated Oxford cloth. A first conveyor belt 22 is sleeved on the two first pulleys 211, and the first conveyor belt 22 is used to drive the clamping components 4 to move. The movement frequencies and movement trajectories of the first conveyor belt 22 and the second conveyor belt 23 are the same.

[0038] In the present invention, the laser cutting head 13 slides on the transverse slide rail 12, and the transverse slide rail 12 slides on the longitudinal slide rail 11, so that the laser cutting head 13 can move in any arc. By arranging two laser cutting heads 13 on the transverse slide rail 12, the edge cutting efficiency can be improved. The principle of this edge cutting device is similar to that of the existing laser edge cutting device. The difference is that when the second conveyor belt 23 conveys the coated Oxford cloth, the first conveyor belt 22 moves synchronously with the second conveyor belt 23. The first conveyor belt 22 drives the clamping assembly 4 to move synchronously. A part of the clamping assembly 4 slides on the first guiding groove 6, and the other part slides on the second guiding groove 61. When the clamping assembly 4 is located on both sides of the lower channel and the upper channel of the first guiding groove 6, the clamping parts of the clamping assembly 4 are in a separated state. At this time, the clamping assembly 4 does not clamp the coated Oxford cloth. When the clamping assembly 4 moves to the middle part of the upper channel of the first guiding groove 6 driven by the first conveyor belt 22, under the guidance of the first guiding groove 6, the clamping parts of the clamping assembly 4 are combined to clamp and limit the coated Oxford cloth, and drive the coated Oxford cloth to move synchronously with the second conveyor belt 23, so that the coated Oxford cloth will not shift during the edge cutting process due to external factors. When the edge cutting is completed, the conveying and clamping assembly 4 is separated and contacts the clamping of the coated Oxford cloth again under the action of the first guiding groove 6, so that the user can separate the edge-cut coated Oxford cloth. By arranging a plurality of continuous clamping assemblies 4, the clamping range of the clamping assembly 4 on the coated Oxford cloth can be evenly distributed, making the clamping effect more uniform and stable.

[0039] Example 2: Refer to Figures 1-8, a laser trimming device for coated Oxford cloth, which is basically the same as that in Embodiment 1. Further, the clamping assembly 4 includes an upper clamping plate 41, a lower clamping plate 42, a limiting rod 421 and a sliding shaft 43. The limiting rod 421 is fixedly connected to the lower clamping plate 42, the upper clamping plate 41 is slidably connected to the limiting rod 421, the sliding shaft 43 is fixedly connected to the upper clamping plate 41, the sliding shaft 43 is slidably connected to the first guiding groove 6, a sliding rod 44 is slidably connected to the second guiding groove 61, the lower clamping plate 42 is slidably connected to the sliding rod 44, a fixing block 5 is fixedly connected to the first conveyor belt 22, a plugging shaft 51 is fixedly connected to the fixing block 5, a limiting block 53 is slidably connected to the plugging shaft 51, a tension spring 52 is connected between the limiting block 53 and the fixing block 5, and the tension spring 52 is used to pull the limiting block 53 to move towards the fixing block 5. A second sliding groove 531 is formed on the limiting block 53, the sliding shaft 43 slides on the second sliding groove 531. A first sliding groove 62 is formed on the support table 1, an upper pressing rod 3 is slidably connected to the first sliding groove 62, a compression spring 32 is connected between the upper pressing rod 3 and the first sliding groove 62, a fixed pressing rod 31 is fixedly connected to the support table 1, and the upper pressing rod 3 and the fixed pressing rod 31 are used to clamp and flatten the coated Oxford cloth. Guide rods 321 are fixedly connected to both ends of the upper pressing rod 3, a guiding inclined surface 322 is formed on the guide rod 321, and the guide rod 321 is used to guide the clamping assembly 4 to move along the guiding inclined surface 322 while moving in the first guiding groove 6. The guide rod 321 is arranged above the clamping assembly 4. When the clamping assembly 4 moves along the first guiding groove 6 to the lower part of the guide rod 321, the clamping assembly 4 drives the guide rod 321 to move upward to release the clamping and flattening of the upper pressing rod 3 on the coated Oxford cloth. A servo motor 2 is fixedly connected to the support table 1, and the output end of the servo motor 2 is fixedly connected to the rotating shaft 21.

[0040] In the present invention, by driving the fixed block 5 on the first conveyor belt 22, the insertion shaft 51 and the limit block 53 can be driven to move together. The limit block 53 drives the sliding shaft 43 and the upper clamping plate 41 to move together. Under the limitation of the limit rod 421, the upper clamping plate 41 drives the lower clamping plate 42 to move together, so as to realize the synchronous movement of the first conveyor belt 22 driving the entire clamping assembly 4. When the lower clamping plate 42 slides on the second guiding groove 61 through the sliding rod 44, the surface of the lower clamping plate 42 is always flush with the second conveyor belt 23, avoiding the phenomenon of wrinkles generated when clamping the coated Oxford cloth due to the change of the clamping position. When the upper clamping plate 41 moves to the middle of the upper horizontal groove of the first guiding groove 6, it will drive the upper clamping plate 41 to move downward and fit with the lower clamping plate 42 under the guidance of the first guiding groove 6, so as to clamp and fix the coated Oxford cloth on the lower clamping plate 42 and move together with the second conveyor belt 23. Until the upper clamping plate 41 moves to both ends of the upper horizontal groove of the first guiding groove 6, it drives the upper clamping plate 41 to move upward under the guidance of the first guiding groove 6, so as to release the clamping effect between the upper clamping plate 41 and the lower clamping plate 42, and continue to clamp the Oxford cloth after rotating one circle along the first guiding groove 6. The main working cutting area of the laser cutting head 13 is located in the interval clamped by the clamping assembly 4. Anti-slip lines made of rubber material can be provided on the corresponding surfaces of the upper clamping plate 41 and the lower clamping plate 42, and the firmness of clamping can be increased by increasing the friction force with the coated Oxford cloth during clamping;

[0041] When the compression spring 32 presses the upper pressure rod 3 against the fixed pressure rod 31, a clamping effect on the coated Oxford cloth will be formed, and this clamping force is a flexible clamping. After the clamping assembly 4 clamps the coated Oxford cloth in front and drives the coated Oxford cloth to continue moving together. At this time, if there are wrinkles in the coated Oxford cloth between the clamping assembly 4 and the fixed pressure rod 31 along the forward direction, under the clamping effect of the clamping assembly 4, the fixed pressure rod 31 and the upper pressure rod 3, the surface tension of the coated Oxford cloth will be enhanced, so that the wrinkles on the coated Oxford cloth will be flattened. Also, due to the weak clamping force between the upper pressure rod 3 and the fixed pressure rod 31 under the action of the compression spring 32, after the wrinkles on the coated Oxford cloth are flattened, the clamping assembly 4 will drive the coated Oxford cloth to continue to be transported forward. At the same time, in order to facilitate the user to place the coated Oxford cloth at the beginning, guide rods 321 are arranged on both sides of the upper pressure rod 3. The guide rods 321 are located above the sliding shaft 43. When the sliding shaft 43 slides along the first guide groove 6 on one side of the upper pressure rod 3, it will drive the guide rod 321 to move upward, so as to release the clamping of the upper pressure rod 3 on the coated Oxford cloth, and it is also convenient for the user to pass through the middle of the upper pressure rod 3 and the fixed pressure rod 31 when placing the coated Oxford cloth at the beginning. At the same time, the intermittent clamping can reduce the damage problem caused by the friction between the movement of the coated Oxford cloth and the upper pressure rod 3 and the fixed pressure rod 31 during the clamping process. The guide rod 321 extends all the way to the horizontal groove at the lower part of the upper layer of the first guide groove 6, so that when the sliding shaft 43 drives the upper clamping plate 41 to move downward to clamp the lower clamping plate 42, the sliding shaft 43 releases the lifting limit on the upper pressure rod 3, and the upper pressure rod 3 forms a short-term clamping on the coated Oxford cloth and jointly completes the flattening of the coated Oxford cloth with the clamping assembly 4. Then, when the next set of clamping assemblies moves over, the upper pressure rod 3 is lifted again. When the equipment stops running after trimming the edges of the coated Oxford cloth, it is necessary to ensure that a set of clamping assemblies 4 stays in the state of lifting the upper pressure rod 3, so as to facilitate the user to place the coated Oxford cloth when using it next time;

[0042] The guiding inclined surfaces 322 opened on the guiding rods 321 are respectively opened at the positions of the vertical grooves at both ends corresponding to the first guiding groove 6 and the horizontal groove at the lower part of the upper layer of the first guiding groove 6, so that when the limiting block 53 follows the clamping assembly 4 and rotates from below to above, it can contact the guiding inclined surface 322, and moves in the direction close to the second conveyor belt 23 under the guidance of the guiding inclined surface 322 with the forward movement. After the clamping assembly 4 completes the clamping of the coated Oxford cloth, the guiding inclined surface 322 gradually releases the limit on the limiting block 53, and the tension spring 52 continuously provides a pulling force for the limiting block 53. After the limiting block 53 loses the limit, the tension spring 52 pulls the limiting block 53 to drive the clamping assembly 4 to pull to both sides, so as to pull the coated Oxford cloth clamped by the clamping assembly 4 to both sides, so as to increase the surface tension of the coated Oxford cloth and flatten the wrinkles on the surface of the coated Oxford cloth to both sides.

[0043] Example 3: Refer toFigures 1-8 , a method for laser trimming of coated Oxford cloth, mainly including the following steps:

[0044] S1. Input the shape and size of the coated Oxford cloth to be cut into a computer or a control terminal in advance;

[0045] S2. Select one end of the coated Oxford cloth, and pass the end of the coated Oxford cloth through the middle of the fixed pressure bar 31 and the upper pressure bar 3;

[0046] S3. Place the coated Oxford cloth on the second conveyor belt 23, and place the extended parts at both ends of the coated Oxford cloth on the lower clamping plate 42 in the opened clamping assembly 4. Only one section of the coated Oxford cloth needs to be placed on the second conveyor belt 23, and it is not necessary to cover the entire second conveyor belt 23;

[0047] S4. Start the device, and the servo motor 2 drives the clamping assembly 4 and the second conveyor belt 23 to move synchronously;

[0048] S5. Through the movement of the transverse slide rail 12 and the movement of the laser cutting head 13, the laser cutting head 13 can perform trimming of any shape;

[0049] S6. Collect the coated Oxford cloth after trimming from the other end of the second conveyor belt 23.

[0050] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content as equivalent embodiments within the scope of the technical solution of the present invention. However, as long as it does not depart from the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the present invention.
