Description

Technical Field

[0001] This utility model relates to the field of blanket processing technology, specifically to a device for processing the rough edges of blankets. Background Technology

[0002] Blankets are a common type of bedding, providing warmth. They are thinner than quilts and are mostly made of animal fibers or chemical fibers such as acrylic and viscose. Some are made of a blend of animal and chemical fibers. During the production of blankets, loose threads or excess fabric may appear at the edges, requiring trimming to improve the blanket's appearance.

[0003] The existing Chinese utility model patent with publication number CN222893419U discloses a trimming device for blanket production, specifically relating to the field of blanket trimming. It includes a workbench, a mounting frame fixedly installed on one side of the workbench, a support frame fixedly installed inside the mounting frame, an adjusting screw rotatably connected inside the support frame, a limit frame threadedly connected to the outer side of the adjusting screw, and the limit frame slidably connected to the inner side of the mounting frame. A handle is fixedly installed at one end of the adjusting screw, a sleeve rotatably connected to the inner side of the limit frame, a second motor fixedly installed inside the sleeve, a cutting blade fixedly installed at the output end of the second motor, and a positioning inner rod slidably connected to the inner side of the sleeve. This utility model, by setting up a cutting blade and limiting the blanket with pressure rollers on both sides, avoids wrinkles in the blanket when it is cut and trimmed by the cutting blade, improves the flatness of the blanket, and thus avoids uneven cutting. Furthermore, the height of the fixed frame can be controlled to accommodate blankets of different thicknesses.

[0004] The aforementioned trimming device removes burrs by rotating a cutter. This method causes the cut-off portion to fly out as the cutter rotates. Furthermore, the cutter cannot maintain relative pressure with the blanket during operation, which may result in incomplete removal of thread ends. Additionally, damage to the cutter blade may cause thread ends to get caught in the notch and rotate with the cutter, leading to snagging. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a device for processing rough edges in blanket manufacturing, which solves the problems that the cutter cannot maintain relative pressure with the edge of the blanket and that the cut-off portion flies out as the cutter rotates, making waste collection inconvenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A blanket edge treatment device includes a bracket, and a processing mechanism for treating the edges of the blanket is disposed above the bracket. The processing mechanism includes: A conveying assembly, located above the tray, is used to convey blankets; The cutting assembly includes a guide rod fixedly installed inside a bracket, a movable frame movably installed on the outer side of the guide rod, a bidirectional lead screw inserted through the center of the movable frame, an adjusting motor connected to one end of the bidirectional lead screw, a flat-blade cutter fixedly installed on one side of the movable frame, a limit post fixedly installed above the movable frame, a connecting frame fixedly installed on the outer side of the limit post, a beveled cutter fixedly installed on one side of the connecting frame, and a downward pressure cylinder provided above the connecting frame.

[0007] Preferably, the conveying assembly includes shuttle rollers interlaced on both sides of the bracket, a conveying motor connected to one side of the shuttle rollers, a support rod fixedly installed above the bracket, a connecting column interlaced below the support rod, a spring sleeved on the outside of the connecting column, and a pressure roller interlaced at the bottom end of the connecting column.

[0008] Preferably, the bracket has a trapezoidal protrusion at its center, the shuttle rollers are arranged in pairs on the front and rear sides of the bracket, the shuttle rollers are rotatably connected to the bracket, the conveyor motor is fixedly connected to the bracket, and the shaft of the conveyor motor is fixedly connected to one end of the shuttle roller.

[0009] Preferably, the connecting column and the support rod are slidably connected, the outer side of the connecting column is provided with a disc-shaped protrusion structure, the pressure roller and the connecting column are rotatably connected, and the pressure roller is located between two shuttle rollers.

[0010] Preferably, the movable frame and the guide rod are slidably connected, the movable frame is movably connected to the bidirectional lead screw through a threaded structure, the outer surface of the connection between the two ends of the bidirectional lead screw and the bracket is unthreaded, and one end of the bidirectional lead screw is fixedly connected to the rotating shaft of the adjusting motor.

[0011] Preferably, the adjusting motor is fixedly connected to the outer side of the bracket, the connecting frame and the limiting post are slidably connected, the blades of the oblique blade and the flat blade face opposite directions, and the top of the pressing cylinder is fixedly connected to the top of the column above the movable frame.

[0012] Beneficial effects This utility model provides a device for processing rough edges in blanket manufacturing. Compared with the prior art, it has the following advantages: (1) The burr removal device for blanket processing achieves stable pressure control through the cooperation of a pressing cylinder, a connecting frame, a limiting post, and two types of cutters. The pressing cylinder provides a continuous and adjustable downward driving force. When cutting is required, the pressing cylinder pushes the connecting frame to move. The limiting post precisely restricts the movement direction of the connecting frame to prevent it from shifting during movement, ensuring that the oblique blade cutter on the connecting frame always maintains a preset contact trajectory with the flat blade cutter on the movable frame. During the process of the oblique blade cutter approaching and contacting the flat blade cutter, the pressure of the pressing cylinder is transmitted to the oblique blade cutter through the connecting frame and then acts on the edge of the blanket, so that the relative pressure between the cutter and the edge of the blanket is always stable, effectively avoiding the situation where the burrs cannot be completely removed due to insufficient pressure, and also preventing the blanket body from being damaged by excessive pressure.

[0013] (2) The blanket processing edge removal device adopts a static bonding cutting structure of a flat blade cutter and a beveled blade cutter. During the cutting process, the flat blade cutter is fixed on the movable frame and remains stationary, while the beveled blade cutter moves towards the flat blade cutter under the drive of the connecting frame. The edge of the blanket is cut by the bonding of the two blades, rather than relying on the cutting force generated by the rotation of the cutter. This cutting method does not generate centrifugal force due to the rotation of the cutter. The cut edge will not be driven by the rotation force and will not fly around. Instead, it will fall naturally on both sides of the trapezoidal structure in the bracket along the direction of blanket conveying. The staff can easily collect the waste material, which completely solves the problem of waste splashing and difficulty in collection caused by traditional rotating cutters.

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a device for processing the rough edges of a blanket includes a bracket 1, and a processing mechanism 2 for processing the edges of the blanket is arranged above the bracket 1. The processing mechanism 2 includes: A conveying assembly 21, positioned above the bracket 1, is used to convey blankets. The conveying assembly 21 includes shuttle rollers 211 interlaced on both sides of the bracket 1. A conveying motor 212 is connected to one side of each shuttle roller 211. A support rod 213 is fixedly installed above the bracket 1. A connecting column 214 is interlaced below the support rod 213. A spring 215 is sleeved on the outer side of the connecting column 214. A pressure roller 216 is interlaced at the bottom end of the connecting column 214. A trapezoidal protrusion is provided at the center of the bracket 1. Two shuttle rollers 211 are arranged as a group and are set on the front and rear sides of the bracket 1. The shuttle rollers 211 and the bracket 1 are rotatably connected. The conveyor motor 212 is fixedly connected to the bracket 1. The rotating shaft of the conveyor motor 212 is fixedly connected to one end of the shuttle roller 211. The connecting column 214 and the support rod 213 are slidably connected. The outer side of the connecting column 214 is provided with a disc-shaped protrusion structure. The pressure roller 216 is rotatably connected to the connecting column 214 and is located between the two shuttle rollers 211.

[0017] Specifically, the downward force provided by the spring 215 to the connecting column 214 makes the pressure roller 216 and the two shuttle rollers 211 staggered in height. While ensuring the blanket tension is easy to trim, it can increase the relative friction between the blanket and the shuttle rollers 211, so that the shuttle rollers 211 can restrict the blanket to the center of the bracket 1 during rotation.

[0018] The cutting assembly 22 includes a guide rod 221 fixedly installed inside the bracket 1. A movable frame 222 is movably installed on the outer side of the guide rod 221. A bidirectional lead screw 223 is inserted through the center of the movable frame 222. One end of the bidirectional lead screw 223 is connected to an adjusting motor 224. A flat blade cutter 225 is fixedly installed on one side of the movable frame 222. A limit post 226 is fixedly installed above the movable frame 222. A connecting frame 227 is fixedly installed on the outer side of the limit post 226. A beveled blade cutter 228 is fixedly installed on one side of the connecting frame 227. A pressing cylinder is provided above the connecting frame 227. 229. The movable frame 222 and the guide rod 221 are slidably connected. The movable frame 222 is movably connected to the double-acting screw 223 through a threaded structure. The outer side of the connection between the two ends of the double-acting screw 223 and the bracket 1 is unthreaded. One end of the double-acting screw 223 is fixedly connected to the shaft of the adjusting motor 224. The adjusting motor 224 is fixedly connected to the outer side of the bracket 1. The connecting frame 227 and the limiting post 226 are slidably connected. The blades of the oblique blade cutter 228 and the flat blade cutter 225 face opposite directions. The top of the pressing cylinder 229 is fixedly connected to the top of the column above the movable frame 222.

[0019] Specifically, the angle of the movable frame 222 is limited by the guide rod 221. Since the movable frame 222 and the bidirectional lead screw 223 are connected by threads, during the process of the adjusting motor 224 driving the bidirectional lead screw 223 to rotate, the bidirectional lead screw 223 can adjust the spacing of the movable frame 222 to adjust the relative position between the flat blade cutter 225 and the oblique blade cutter 228 to adapt to blankets of different widths. During the processing, the start and stop of the winding equipment and the extension and retraction of the pressing cylinder 229 are coordinated. The pressing cylinder 229 drives the connecting frame 227 and the oblique blade cutter 228 to move towards the flat blade cutter 225 to trim the edge of the blanket. The limiting post 226 can limit the movement direction of the connecting frame 227 so that the oblique blade cutter 228 can fit against the flat blade cutter 225 during the cutting process.

[0020] Specifically, the conveyor motor 212 is a Marathon I212, the regulating motor 224 is a FE-22442, and the pressing cylinder 229 is an SCS-250. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0021] During operation, firstly, the conveyor motor 212 is started, which drives the shuttle rollers 211 on both sides of the bracket 1 to rotate, placing the blanket with rough edges to be processed on the shuttle rollers 211. A connecting column 214 is inserted below the support rod 213 above the bracket 1. The spring 215 sleeved on the outside of the connecting column 214 pushes the connecting column 214 downward through its own elastic force, so that the pressure roller 216 at the bottom of the connecting column 214 presses tightly on the surface of the blanket. The pressure roller 216 cooperates with the shuttle roller 211 to ensure the tension of the blanket during the conveying process and increase the relative friction between the blanket and the shuttle roller 211, so as to stably convey the blanket to the center of the bracket 1. Next, the adjusting motor 224 is started according to the width of the blanket. The adjusting motor 224 drives the bidirectional lead screw 223 to rotate. Since the movable frame 222 and the guide rod 221 are slidably connected and connected to the bidirectional lead screw 223 through a threaded structure, when the bidirectional lead screw 223 rotates, it drives the movable frame 222 to slide along the guide rod 221, adjusting the distance between the two movable frames 222, and then adjusting the relative position of the flat blade cutter 225 on one side of the movable frame 222 and the oblique blade cutter 228 on the side of the connecting frame 227 above the movable frame 222, so that it is adapted to the current blanket width. Finally, in coordination with the start and stop control of the winding equipment, the pressing cylinder 229 extends and retracts. The pressing cylinder 229 drives the connecting frame 227 to slide along the limiting post 226 above the movable frame 222, so that the oblique blade cutter 228 moves towards the flat blade cutter 225 and fits together, so as to cut and trim the rough edges of the conveyed blanket. After the trimming is completed, the blanket continues to be conveyed to the next process by the shuttle roller 211. This cycle is repeated to achieve continuous blanket rough edge treatment.
