Description

Technical Field

[0001] The utility model relates to the technical field of seat cover processing equipment, in particular to a seat cover cutting device. Background Art

[0002] Seat covers are covers for car seats. They protect the original car seats from being dry and clean and prevent leather aging. Seat covers require fabric cutting during production, so special cutting devices are required.

[0003] A cutting structure for the production of automobile seat dust covers is disclosed in the Chinese utility model patent with the announcement number CN219685722U. The device can clamp and fix the material by using the mutual cooperation between the structures on the processing seat when cutting the material through the fixing mechanism, thereby ensuring the stability during cutting and improving the cutting quality. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, the fixing mechanism can only clamp the material but is difficult to smooth it, which makes it easy for the cut edge to be skewed due to the wrinkles of the material during cutting, thereby affecting the processing quality of the seat cover. In order to prevent the above situation from occurring, the operator is required to manually smooth the material while clamping it, which is not only troublesome but also reduces the processing efficiency of the seat cover. For this reason, we provide a seat cover cutting device. Utility Model Content

[0005] In order to solve the problem in the above background technology that the cutting quality is easily affected by material wrinkles due to the lack of an integrated flattening structure, the utility model provides a seat cover cutting device.

[0006] The utility model is implemented by the following technical scheme: a seat cover cutting device, including a cutting table, a connecting plate arranged above the cutting table, a cutting knife fixedly installed at the bottom of the connecting plate, a position changing component arranged between the cutting table and the connecting plate, and an automatic smoothing component arranged at the bottom of the connecting plate.

[0007] The automatic smoothing assembly includes brackets symmetrically hinged on both sides of the bottom of the connecting plate, leveling rollers rotatably connected to the ends of the brackets, sliding rods symmetrically fixedly connected to the bottom of the connecting plate, sliders slidably connected to the outside of the sliding rods, springs sleeved on the outside of the sliding rods, and a connecting rod hinged between the sliders and the middle of the brackets.

[0008] As a further improvement of the above scheme, the position change component includes a connecting frame fixedly connected to the cutting table, a disc rotatably connected to the bottom of the connecting frame through a rotating shaft, a stepper motor fixedly installed at the bottom of the connecting frame, a bevel gear fixedly sleeved on the outside of the rotating shaft and the outside of the stepper motor rotor and meshing with each other, a screw rod 1 rotatably connected to the bottom of the disc, a moving block threadedly connected to the screw rod 1, a moving groove opened at the bottom of the moving block, a screw rod rotatably connected inside the moving groove, a movable block threadedly connected to the screw rod 2, an electric push rod fixedly installed at the bottom of the movable block and whose telescopic end is fixedly connected to the connecting plate, and two groups of rotating motors coaxially fixedly connected to one end of the screw rod 1 and the screw rod 2, respectively, to facilitate the adjustment of the cutting position and increase the scope of application of the device.

[0009] As a further improvement of the above scheme, the four corners of the top of the cutting table are fixedly connected with L-shaped parts, and a screw is threadedly connected to the L-shaped part. The bottom of the screw is rotatably connected to a circular pressure plate, and the top of the screw is fixedly connected to a hand wheel, which is convenient for clamping and fixing the material and ensuring stability during cutting.

[0010] As a further improvement of the above solution, the side section of the slide bar is a rectangular structure, which ensures that the slide block can stably move horizontally.

[0011] As a further improvement of the above solution, a limiting rod is fixedly connected to the upper side of the screw rod 1 and is slidably connected to the moving block, which can guide the horizontal movement of the moving block.

[0012] As a further improvement of the above solution, the movable block is slidably connected to the movable groove, which can guide the horizontal movement of the movable block.

[0013] As a further improvement of the above solution, anti-slip protrusions are evenly provided on the bottom of the circular pressure plate, which can increase the friction force to improve the fixing and clamping effect of the material.

[0014] As a further improvement of the above solution, the bottoms of the two groups of leveling rollers are on the same horizontal line, which facilitates stretching and tensioning the material to both sides.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model drives the cutting knife to approach the material through the electric push rod and drives the two sets of leveling rollers to move down at the same time. When the two sets of leveling rollers first contact the material, due to the continuous pushing of the electric push rod and the hinged action of the bracket, the slider and the connecting rod, the bracket will deflect outward and push the slider to slide on the slide rod to compress the spring. When the two sets of brackets deflect outward on both sides, they will also drive the leveling rollers to roll outward on both sides on the material, so that the material can be automatically stretched and tightened to achieve a smoothing effect, effectively avoiding the problem of affecting the cutting quality due to material wrinkles due to the lack of an integrated leveling structure.

[0017] 2. The utility model can change the cutting position at any time according to the need by setting up a position change component, and utilizes the meshing action between the stepping motor and the bevel gear, so that it can also drive the cutting knife to cut the material at an angle, which effectively improves the practicality of the device. At the same time, the use of the automatic smoothing component in conjunction with the position change component makes it possible to automatically tension and smooth the materials on both sides of the cutting position when cutting the material in any direction at any position, which effectively ensures the cutting quality of the material and further improves the practicality of the device.

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Embodiment 1:

[0025] Please combine Figure 1-3A seat cover cutting device of this embodiment includes a cutting table 1, a connecting plate arranged above the cutting table 1, a cutting knife 2 fixedly installed at the bottom of the connecting plate, a position changing component arranged between the cutting table 1 and the connecting plate, and an automatic smoothing component arranged at the bottom of the connecting plate.

[0026] The automatic smoothing assembly includes a bracket 101 symmetrically hinged on both sides of the bottom of the connecting plate, a leveling roller 102 rotatably connected to the end of the bracket 101, a sliding rod 103 symmetrically fixedly connected to the bottom of the connecting plate, a slider 104 slidably connected to the outside of the sliding rod 103, a spring 105 sleeved on the outside of the sliding rod 103 and a connecting rod 106 hinged between the slider 104 and the middle part of the bracket 101. The side profile of the sliding rod 103 is a rectangular structure to ensure that the slider 104 can move horizontally stably. The bottoms of the two sets of leveling rollers 102 are on the same horizontal line, which is convenient for stretching and tensioning the material to both sides.

[0027] The position conversion assembly includes a connecting frame fixedly connected to the cutting table 1, a disc 201 rotatably connected to the bottom of the connecting frame through a rotating shaft, a stepper motor fixedly installed at the bottom of the connecting frame, a bevel gear 202 fixedly sleeved on the outside of the rotating shaft and the outside of the stepper motor rotor and meshing with each other, a screw rod 203 rotatably connected to the bottom of the disc 201, a moving block 204 threadedly connected to the screw rod 203, a moving groove provided at the bottom of the moving block 204, a screw rod 205 rotatably connected to the inside of the moving groove, and a screw rod 205 threadedly connected to the screw rod 205. The movable block, an electric push rod 206 fixedly installed at the bottom of the movable block and with the telescopic end fixedly connected to the connecting plate, and two sets of rotating motors coaxially fixedly connected to one end of the screw rod 203 and the screw rod 205 respectively, are convenient for adjusting the cutting position and increase the application range of the device. The upper part of the screw rod 203 is fixedly connected to the limit rod 5 and is slidably connected to the movable block 204, which can guide the horizontal movement of the movable block 204. The movable block is slidably connected to the movable groove, which can guide the horizontal movement of the movable block.

[0028] The implementation principle of a seat cover cutting device in the embodiment of the present application is as follows: the material is laid flat on the cutting table 1, and the electric push rod 206 is started to drive the cutting knife 2 to move vertically downward to cut the material. The electric push rod 206 pushes the cutting knife 2 to approach the material and drives the two sets of leveling rollers 102 to move downward at the same time. When the two sets of leveling rollers 102 first contact the material, due to the continuous push of the electric push rod 206 and the hinged action of the bracket 101 and the slider 104 and the connecting rod 106, the bracket 101 will deflect outward and push the slider 104 to slide on the slide bar 103 to compress the spring 105. When the two sets of brackets 101 deflect to the outside on both sides, they will also drive the leveling rollers 102 to roll on the material to the outside on both sides, so that the material can be automatically stretched and tightened to achieve a smoothing effect. When the cutting blade 2 is in the right position, the bracket 101 will automatically reset under the rebound effect of the spring 105, and the rotating motor drives the screw rod 1 203 to rotate, so that the moving block 204 can be driven to move in the horizontal direction, thereby driving the cutting blade 2 to move in the horizontal direction, and another rotating motor drives the screw rod 205 to rotate, so that the movable block can be driven to move in the vertical direction, thereby driving the cutting blade 2 to move in the vertical direction, and by starting the stepping motor and under the meshing effect of the bevel gears 202, the disc 201 can be driven to rotate, thereby driving the cutting blade 2 to rotate to cut the material in an inclined direction, which is highly practical. At the same time, the use of the automatic smoothing component in conjunction with the position conversion component can automatically tension and smooth the materials on both sides of the cutting position when cutting the material in any direction at any position, thereby effectively ensuring the cutting quality of the material.

[0029] Embodiment 2:

[0030] Based on Example 1, this embodiment is further improved in that: the four corners of the top of the cutting table 1 are fixedly connected with L-shaped parts, the L-shaped parts are threaded with screw rods 3, the bottom of the screw rods 3 is rotatably connected with a circular pressure plate 4, the top of the screw rods 3 is fixedly connected with a hand wheel, and the bottom of the circular pressure plate 4 is evenly provided with anti-skid protrusions. By rotating the screw 3, the circular pressure plate 4 is driven to move vertically downward, so that the material can be pressed and fixed, and the added anti-skid protrusions can increase the friction to improve the fixing and clamping effect of the material.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
