Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blanket trimming, and more specifically to a trimming device for blanket production. Background Art
[0002] Blankets are a commonly used bedding product that has a warming function. Compared with quilts, they are thinner. Their raw materials are mostly animal fibers or chemical fibers such as acrylic and viscose fibers. Some are blended with animal fibers and chemical fibers. When blankets are produced, threads or excess fabric will appear on the edges of the blankets, so trimming is required to improve the aesthetics of the blankets.
[0003] When the existing blanket trimming device is trimming the blanket, wrinkles may appear on the blanket during trimming due to reasons such as blunt cutting blades or the fabric of the blanket. The reduction in flatness will make the trimmed blanket uneven and even cause cutting failure. Therefore, how to design a trimming device for blanket production has become a problem that we currently need to solve. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a trimming device for blanket production, which sets a trimming knife and limits the blanket by pressure rollers on both sides to avoid wrinkles when the blanket is trimmed by the trimming knife, thereby improving the flatness of the blanket and avoiding uneven cutting. At the same time, the height of the fixed frame can be controlled to adapt to blankets of different thicknesses to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a trimming device for blanket production, comprising a workbench, a mounting frame is fixedly installed on one side of the workbench, a supporting frame is fixedly installed on the inner side of the mounting frame, an adjusting screw is rotatably connected inside the supporting frame, the outer side of the adjusting screw is threadedly connected to a limiting frame, the limiting frame is slidably connected to the inner side of the mounting frame, a handle is fixedly installed on one end of the adjusting screw, a sleeve is rotatably connected on the inner side of the limiting frame, a second motor is fixedly installed inside the sleeve, a trimming knife is fixedly installed on the output end of the second motor, a positioning inner rod is slidably connected on the inner side of the sleeve, and a lifting and lowering adjusting rod is rotatably connected inside the mounting frame.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Refer to the instruction manual Figure 1-3 ,like Figure 1 As shown, a trimming device for blanket production according to an embodiment of the utility model comprises a workbench 1, a mounting frame 2 is fixedly mounted on one side of the workbench 1, and a supporting frame 3 is fixedly mounted on the inner side of the mounting frame 2. Figure 2 As shown, the support frame 3 is internally rotatably connected with an adjusting screw 4, the outer side of the adjusting screw 4 is threadedly connected with a limiting frame 5, the limiting frame 5 is slidably connected to the inner side of the mounting frame 2, one end of the adjusting screw 4 is fixedly mounted with a handle 6, and the inner side of the limiting frame 5 is rotatably connected with a sleeve 7, as shown in FIG. Figure 1 As shown, the second motor 21 is fixedly installed inside the sleeve 7, the output end of the second motor 21 is fixedly installed with a trimming knife 8, the inner side of the sleeve 7 is slidably connected with a positioning inner rod 9, the inner side of the mounting frame 2 is rotatably connected with a lifting adjustment rod 10, and the outer side of the lifting adjustment rod 10 is threadedly connected with a fixed frame 11, as shown in FIG. Figure 3 As shown, the interior of the fixed frame 11 is rotatably connected with a first shaft 12 .
[0021] It should be noted that, when trimming is required during the blanket production process, the blanket is wound around the surface of the winding roller 17 on one side, passed through the bottom of the pressure roller 13, and wound around the surface of the winding roller 17 on the other side. The fixed frame 11 is lowered by rotating the lifting adjustment rod 10, thereby driving the pressure rollers 13 on both sides to descend and come into close contact with the blanket. The trimming knife 8 is rotated by starting the second motor 21, thereby cutting and trimming the two sides of the blanket to achieve the purpose of trimming. At the same time, the first motor 19 is started to rotate the pulley 18 rotates, thereby driving the pulley 18 on the other side to rotate through the belt 20, so that the rollers 17 on both sides rotate synchronously, the roller 17 on one side unwinds the blanket, and the roller 17 on the other side rewinds the blanket, so that the blanket slides over the bottom side of the pressure roller 13, and the pressure rollers 13 on both sides limit the blanket to avoid wrinkles when the blanket is cut and trimmed by the trimming knife 8, thereby improving the flatness of the blanket and avoiding uneven cutting. At the same time, the height of the fixed frame 11 can be controlled to adapt to blankets of different thicknesses.
[0022] Further, such as Figure 3 As shown, a pressure roller 13 is fixedly installed on the outer side of the first shaft 12, and a limiting slot frame 14 is fixedly installed on one side of the workbench 1, and the first shaft 12 is slidably connected to the inner side of the limiting slot frame 14, as shown in FIG. Figure 1 As shown, support plates 15 are fixedly installed on both sides of the workbench 1, and a second shaft rod 16 is rotatably connected inside the support plate 15. A roller 17 is fixedly installed on one end of the second shaft rod 16. The number of rollers 17 is set to two, and the two rollers 17 are axially symmetrical about the vertical center line of the workbench 1. A first motor 19 is fixedly installed on one side of the support plate 15, and a pulley 18 is fixedly installed on the output end of the first motor 19. The number of pulleys 18 is set to two, and the two pulleys 18 are axially symmetrical about the vertical center line of the workbench 1. The pulley 18 is fixedly installed on one side of the second shaft rod 16, and a belt 20 is sleeved on the outer side of the pulley 18.
[0023] It should be noted that, when trimming a narrow blanket, the adjusting screw 4 is rotated by turning the handle 6. Two threads with opposite rotation directions are provided on both sides of the adjusting screw 4. When the adjusting screw 4 rotates, the limit frames 5 on both sides are driven to slide inward at the same time, so that the sleeves 7 on both sides slide synchronously on the outside of the positioning inner rod 9, thereby reducing the distance between the trimming knives 8 on both sides, so that blankets of different sizes can be trimmed.
