Description

Technical Field

[0001] This utility model relates to the field of fabric cutting technology, and in particular to a sofa cushion fabric cutting device. Background Technology

[0002] A sofa's structure mainly consists of three parts: the frame, the filling, and the fabric. The frame, as the main supporting structure of the sofa, determines its basic shape. The filling directly affects the sofa's comfort, while the texture and color of the fabric determine the overall quality of the sofa. Commonly used fabrics for cushions include cotton, linen, leather, plush, polyester fiber, and silk. Different fabrics have their own characteristics in terms of texture, performance, and applicable scenarios. In the sofa manufacturing process, cutting devices are used; however, existing cutting devices still have certain shortcomings.

[0003] A sofa plush fabric cutting device, with announcement number CN218880400U, comprises two symmetrically arranged horizontal slots on the top of a worktable, two fabric clamping assemblies symmetrically slidably arranged within the horizontal slots, and a drive assembly arranged within the horizontal slots to move the two fabric clamping assemblies closer to or further apart. Each fabric clamping assembly includes a slider slidably arranged within the horizontal slot, an L-shaped plate at the top of the slider, an electric telescopic rod extending through the top of the L-shaped plate, and a pressing plate at the telescopic end of the electric telescopic rod for pressing the fabric. The top of the worktable is equipped with a cutting assembly for cutting the fabric. However, in this embodiment, after cutting, the fabric must be manually removed before the next round of cutting can begin, which not only increases the intensity of manual labor but also limits the overall cutting efficiency due to the waiting time for material removal. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a sofa cushion fabric cutting device that can press and fix the front and back positions of the fabric at the cutting point during cutting, and drive the connecting rod to move the pressure plate through pressure to flatten the wrinkles of the fabric, so that the fabric is in a taut state for easy cutting. The cut fabric will automatically fall into the storage box for collection under the action of gravity, without the need for manual intervention, thus improving cutting efficiency.

[0006] To achieve the above objectives, the first aspect of this utility model provides a sofa cushion fabric cutting device, comprising: a frame, a conveying assembly, a cutting mechanism, and a cleaning mechanism. The frame is equipped with a storage box, and casters are provided at the bottom of the frame below the storage box.

[0007] In addition, the water purification equipment proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the conveying assembly includes a raw material mounting shaft, two conveying rollers, and a drive motor. The raw material mounting shaft is horizontally mounted on the side wall of the opposite side of the frame. The two conveying rollers are horizontally mounted on the frame, and the roller surfaces of the two conveying rollers are parallel to each other. A drive gear is fixedly sleeved on the same side shaft end of each of the two conveying rollers, and the two drive gears mesh with each other. The drive motor is mounted on a fixed frame and is located directly below the two conveying rollers. A pulley is fixedly sleeved on the outer side of one of the conveying rollers away from the drive gear and the output end of the drive motor. A conveyor belt for transmission connection is sleeved on the outer side of the two pulleys.

[0009] Specifically, the cutting mechanism includes a bracket, an electric telescopic rod, a movable plate, two guide rods, a connecting plate, and a cutting assembly. The bracket is located on the outer wall of the frame; the electric telescopic rod is located at the upper end of the bracket; the top end of the movable plate is connected to the drive end of the electric telescopic rod; the two guide rods are installed at the bottom end of the movable plate, with the ends of both guide rods extending through the frame and below it, connecting to the connecting plate; the ends of the connecting plate away from the guide rods are connected to a dust extraction assembly; and the cutting assembly is installed on the outer wall of the two guide rods.

[0010] Specifically, the cutting assembly includes a horizontal plate, a cutting blade, two connecting rods, and a pressure plate. The horizontal plate is installed on the outer wall of the guide rod between the frame and the moving plate. The cutting blade is installed at the bottom end of the horizontal plate, and two slots are symmetrically opened on the horizontal plate on both sides of the cutting blade. The two connecting rods are arranged in the slots one to one, and torsion springs are sleeved on the outer side of the shaft ends of the two connecting rods. The bottom ends of the two connecting rods are connected to the pressure plate.

[0011] Specifically, one end of the torsion spring is connected to the connecting rod, and the other end is connected to the inner wall of the horizontal plate. The bottom end of the pressure plate is provided with a plurality of rubber protrusions.

[0012] Specifically, the dust collection assembly includes a guide plate, a suction head, and a slide groove. The guide plate is installed on the outer wall of the frame above the storage box. The guide plate has suction holes, a slide groove, and a rectangular slot. The suction holes and the rectangular slot are connected to the slide groove. The suction head is slidably disposed in the slide groove, and the air outlet of the suction head is connected to a flexible hose.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The sofa cushion fabric cutting device of the present invention can press and fix the fabric at both the front and rear positions of the cutting point, and the pressure drives the connecting rod to move the pressure plate, so that the two pressure plates apply opposite forces to the two ends of the fabric. This not only flattens the wrinkles of the fabric, but also keeps the fabric in a taut state for easy cutting, avoiding the problem of uneven cuts. Furthermore, the cut fabric will automatically fall into the storage box under the action of gravity along the guide plate for collection, eliminating the need for manual fabric handling and improving cutting efficiency.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] The water purification treatment equipment of this utility model is described below with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown, the sofa cushion fabric cutting device of this utility model embodiment may include: frame 1, conveying component 2, cutting mechanism 3 and impurity removal mechanism 4.

[0026] The frame 1 is equipped with a storage box 101, and the bottom of the frame 1 below the storage box 101 is equipped with casters 102.

[0027] It should be noted that the movable wheels 102 described in this embodiment are usually four in number. The four movable wheels 102 are symmetrically distributed at the four corners of the bottom of the frame 1. The movable wheels 102 are fixed to the bottom of the frame 1 by bolts or welding to form a rigid connection structure. With the setting of the movable wheels 102, the operator can easily push the frame 1 to move as a whole. When the device moves to the preset working position, the frame 1 can be fixed in the current position by locking the movable wheels 102.

[0028] The conveying assembly 2 is located on the outer wall of the frame 1 and is used to convey the sofa cushion fabric. The cutting mechanism 3 is located on the frame 1 on one side of the conveying assembly 2, and the cutting end of the cutting mechanism 3 corresponds to the fabric conveying path of the conveying assembly 2. The cleaning mechanism 4 includes a fixed frame 401, a dust collection box 402 and a dust collection assembly 403. The fixed frame 401 is installed on the frame 1 below the conveying assembly 2. The dust collection box 402 is installed on the fixed frame 401, and the output end of the dust collection box 402 is connected to a flexible hose 404. The dust collection assembly 403 is installed on the outer wall of the frame 1 on one side of the cutting mechanism 3, and the other end of the dust collection assembly 403 is connected to the flexible hose 404.

[0029] It should be noted that, in this embodiment, the cutting mechanism 3 is not in operation when the conveying component 2 is conveying the fabric.

[0030] Specifically, in the fabric cutting workshop of a sofa manufacturing plant, this device is used to cut the fabric. First, the device is placed on a flat surface, and the rolled cotton sofa cushion fabric is placed on the raw material mounting shaft 201. The conveying component 2 then starts to run.

[0031] It is understandable that the above implementation method can form a continuous conveying path, providing a stable feeding basis for subsequent cutting.

[0032] The sofa cushion fabric is conveyed to the bottom of the cutting mechanism 3 by the conveying component 2. After the front end of the fabric exceeds the preset length of the cutting end of the cutting mechanism 3, the conveying component 2 stops running, and the cutting mechanism 3, which was originally in standby mode, starts working. Driven by the drive component, its cutting end descends rapidly in a direction perpendicular to the fabric conveying path and cuts the fabric.

[0033] After cutting, the cut fabric automatically falls into the collection box 101 under the action of gravity for collection, and the conveying component 2 starts again to continue to pull the roll of fabric out from the raw material mounting shaft 201 to prepare for the next cutting. This cycle is repeated to achieve continuous cutting.

[0034] During the operation of the cutting mechanism 3, the impurity removal mechanism 4 is started simultaneously. As cotton scraps, lint, and other impurities are generated when cutting the fabric, the vacuum pump or centrifugal fan built into the dust collection box 402 starts to operate. A negative pressure field is formed by the dust collection component 403 installed on one side of the cutting mechanism 3 and its suction port facing the cutting area. Under the action of negative pressure, the impurities generated by cutting enter the connected hose 404 through the dust collection component 403 and are transported through the hose 404 to the dust collection box 402 installed on the fixed frame 401 below the conveying component 2. The dust collection box 402 is equipped with a filter assembly, which can intercept and filter impurities to prevent debris from entering the vacuum pump or centrifugal fan and causing damage. The filtered air is discharged through the exhaust port of the dust collection box 402. When the impurities in the dust collection box 402 accumulate to a certain amount, they can be centrally processed by opening the cleaning port of the dust collection box 402, which not only prevents impurities from scattering and polluting the workshop environment, but also prevents them from adhering to the fabric surface and affecting product quality.

[0035] In one embodiment of this utility model, such as Figure 5 As shown, the conveying assembly 2 includes a raw material mounting shaft 201, two conveying rollers 202, and a drive motor 203. The raw material mounting shaft 201 is horizontally mounted on the side wall of the opposite side of the frame 1. The two conveying rollers 202 are horizontally mounted on the frame 1, and the roller surfaces of the two conveying rollers 202 are parallel to each other. A drive gear 204 is fixedly sleeved on the same side shaft end of the two conveying rollers 202, and the two drive gears 204 mesh with each other. The drive motor 203 is mounted on the fixed frame 401 and is located directly below the two conveying rollers 202. A pulley 205 is fixedly sleeved on the outer side of one of the conveying rollers 202 away from the drive gear 204 and the output end of the drive motor 203. A conveyor belt for transmission connection is sleeved on the outer side of the two pulleys 205.

[0036] It should be noted that bearings are provided between the raw material mounting shaft 201, the two conveying rollers 202 and the frame 1 as described in this embodiment.

[0037] Specifically, after the drive motor 203 starts, it drives the pulley 205 on the outer side of its output end to rotate synchronously. Under the transmission action of the conveyor belt, another pulley 205 connected to the pulley 205 via the conveyor belt also rotates. This pulley 205 is fixedly sleeved on the end of one of the conveyor rollers 202 away from the drive gear 204, so the conveyor roller 202 will be driven to rotate. Since the drive gears 204 are fixedly sleeved on the same side shaft end of both conveyor rollers 202, and the two drive gears 204 are meshed, when one of the conveyor rollers 202 rotates, it will... Through the meshing transmission of the drive gear 204, another conveyor roller 202 is driven to rotate synchronously. Since the roller surfaces of the two conveyor rollers 202 are parallel to each other, they will rotate in opposite directions but at the same speed, thereby generating a clamping conveying force. The rolled cotton sofa cushion fabric sleeved on the raw material mounting shaft 201 will gradually unfold under its own weight and the traction of the two conveyor rollers 202. The unfolded fabric will enter between the two conveyor rollers 202. Due to the synchronous counter-rotation of the two conveyor rollers 202, the fabric will be stably clamped between the two rollers and conveyed forward as the conveyor rollers 202 rotate.

[0038] In one embodiment of this utility model, such as Figure 3 As shown, the cutting mechanism 3 includes a bracket 301, an electric telescopic rod 302, a moving plate 303, two guide rods 304, a connecting plate 305, and a cutting assembly 306. The bracket 301 is disposed on the outer wall of the frame 1; the electric telescopic rod 302 is disposed on the upper end of the bracket 301; the top end of the moving plate 303 is connected to the driving end of the electric telescopic rod 302; the two guide rods 304 are installed at the bottom end of the moving plate 303, and the ends of the two guide rods 304 away from the moving plate 303 extend through the frame 1 and below it, and are connected to the connecting plate 305; the ends of the connecting plate 305 away from the guide rods 304 are connected to the dust collection assembly 403; the cutting assembly 306 is installed on the outer wall of the two guide rods 304.

[0039] It should be noted that the two guide rods 304 described in this embodiment are slidably connected to the bracket 301, and the fixed end of the electric telescopic rod 302 is fastened to the upper end face of the bracket 301 by bolts.

[0040] Specifically, when the conveying component 2 conveys the sofa cushion fabric to the preset position below the cutting mechanism 3 and stops operating, the cutting mechanism 3 starts to work: the electric telescopic rod 302 receives the start signal, its drive end extends downward, and drives the moving plate 303 connected to it to move downward synchronously. Since the two guide rods 304 are installed at the bottom of the moving plate 303 and are slidably connected to the bracket 301, when the moving plate 303 moves down, it will carry the two guide rods 304 to slide vertically downward along the bracket 301. The cutting component 306 installed on the outer wall of the two guide rods 304 gradually approaches the fabric surface as the guide rods 304 move down. Under the continuous downward pressure applied by the electric telescopic rod 302, the cutting action is completed along the fabric surface.

[0041] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the cutting assembly 306 includes a horizontal plate 3061, a cutting blade 3062, two connecting rods 3063, and a pressure plate 3064. The horizontal plate 3061 is installed on the outer wall of the guide rod 304 between the frame 1 and the moving plate 303. The cutting blade 3062 is installed at the bottom end of the horizontal plate 3061, and two slots are symmetrically opened on the horizontal plate 3061 on both sides of the cutting blade 3062. The two connecting rods 3063 are arranged in the slots one to one, and torsion springs 5 ​​are sleeved on the outer side of the shaft end of the two connecting rods 3063. The bottom ends of the two connecting rods 3063 are connected to the pressure plate 3064.

[0042] Specifically, the pressure plate 3064 is the first to come into contact with the fabric. Since the bottom ends of the two connecting rods 3063 are connected to the pressure plate 3064, and the outer side of the shaft end of the connecting rod 3063 is fitted with a torsion spring 5, when the pressure plate 3064 touches the fabric surface, the guide rod 304 continues to move downward. At this time, the connecting rod 3063 will rotate upward in the slot, the torsion spring 5 will be compressed and generate a reverse elastic force, and the pressure plate 3064 will press tightly against the fabric surface, firmly fixing the fabric on both sides of the cutting position and pulling the fabric to both sides to prevent the fabric from shifting or wrinkling due to force during the cutting process, thus ensuring the accuracy of the cutting.

[0043] In one embodiment of this utility model, such as Figure 4 As shown, one end of the torsion spring 5 is connected to the connecting rod 3063, and the other end is connected to the inner wall of the horizontal plate 3061. Multiple rubber protrusions are arranged in an array at the bottom of the pressure plate 3064.

[0044] It should be noted that the rubber bumps described in this embodiment are adhered to the bottom of the pressure plate 3064 by synthetic adhesive.

[0045] Specifically, after cutting, the drive end of the electric telescopic rod 302 retracts upward, causing the guide rod 304 and the cutting assembly 306 to move upward. At this time, the pressure plate 3064 first detaches from the fabric surface, the torsion spring 5 returns to its original state, and drives the connecting rod 3063 back to its initial position, thereby resetting the pressure plate 3064. The rubber protrusions prevent the pressure plate 3064 from directly contacting the fabric, avoiding indentations that could affect product quality. At the same time, the rubber protrusions increase friction and improve efficiency.

[0046] In one embodiment of this utility model, such as Figure 4 As shown, the vacuuming assembly 403 includes a guide plate 4031, a suction head 4032, and a slide 4033. The guide plate 4031 is installed on the outer wall of the frame 1 above the storage box 101. The guide plate 4031 has an adsorption hole 4034, a slide 4033, and a rectangular slot 4035. The adsorption hole 4034 and the rectangular slot 4035 are connected to the slide 4033. The suction head 4032 is slidably disposed in the slide 4033, and the air outlet of the suction head 4032 is connected to the hose 404.

[0047] It should be noted that the guide plate 4031 described in this embodiment has an inclined surface at its upper end, a rectangular slot 4035 is formed on the inclined surface, and an adsorption hole 4034 is formed on the side wall.

[0048] Specifically, when the guide rod 304 moves the suction head 4032 downwards, the suction head 4032 aligns with the adsorption hole 4034, thereby adsorbing the vertical fabric onto the guide plate 4031. This prevents the fabric from shaking during cutting and causing wrinkles. After cutting, the guide rod 304 moves the suction head 4032 back to its original position. Because the rectangular slot 4035 is closer to the cutting area, and its beveled design guides cotton debris, lint, and other impurities generated during cutting to gather at the rectangular slot 4035, the suction head 4032 can efficiently suck these impurities in through the rectangular slot 4035. The impurities enter the hose 404 through the outlet of the suction head 4032 and are finally transported to the dust collection box 402 for collection, preventing impurities from scattering and polluting the workshop environment or adhering to the fabric surface and affecting subsequent processing.

[0049] In summary, the sofa cushion fabric cutting device of this utility model can apply opposite forces to both ends of the fabric, so that the wrinkles on the fabric are flattened by these two opposite forces, and the fabric is also tightened, avoiding the problem of uneven cuts caused by loose or wrinkled fabric. The cut fabric will automatically fall into the storage box 101 under the action of gravity along the guide plate 4031 for collection, eliminating the need for manual fabric handling and improving cutting efficiency.
