[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A preparation device for a rebound seat cover, comprising a base with a bracket fixedly connected to the upper surface, a guide assembly slidably connected in the inner cavity of the bracket, a driving assembly for pushing the guide assembly to move is installed on the top of the bracket, a connecting seat is installed on the guide assembly, an annular cutter is fixedly connected to the lower surface of the connecting seat, an anti-deformation structure is slidably connected to the annular cutter, the anti-deformation structure comprises a plurality of sliding holes vertically opened on the side wall of the annular cutter, and also comprises an outer pressure ring sleeved on the outer surface of the annular cutter and an inner pressure ring embedded in the inner cavity of the annular cutter, the outer pressure ring and the top of the inner pressure ring are fixedly connected by a connecting plate passing through the sliding holes, and the outer pressure ring and the top of the inner pressure ring are fixedly connected to the connecting seat by an elastic connecting piece.
[0008] By adopting the above technical solution, when using it, the user first places the fabric to be cut on the base, and then starts the cylinder to push the guide plate to slide down along the guide groove, driving the annular cutter installed on the connecting seat to move downward. Since the bottom heights of the outer pressure ring and the inner pressure ring on the inner and outer sides of the annular cutter are lower than the bottom height of the annular cutter, the outer pressure ring and the inner pressure ring first fit with the fabric. As the annular cutter continues to move downward, the outer pressure ring and the inner pressure ring drive the connecting plate to move up along the sliding hole under the support of the fabric, and squeeze the spring to contract, and the spring pushes the outer pressure ring and the inner pressure ring in the opposite direction under the action of its own elastic force to press the fabric to prevent the fabric from deforming during the cutting process, and tries to avoid the problem that the existing cutting device cannot press the cutting position during the cutting process, and the fabric is easily deformed due to the squeezing of the cutting knife during the cutting process, resulting in deviation in the cutting size, which seriously affects the cutting quality.
[0009] Optionally, the bracket has a U-shaped structure, and the guide assembly includes a guide groove opened on the inner walls of the two vertical sections of the bracket and a guide plate arranged inside the bracket, with both ends extending into the guide groove and slidingly connected to the side wall of the bracket through the guide groove, and the connecting seat is fixedly connected to the lower surface of the guide plate.
[0010] By adopting the above technical solution, a guide groove and a guide plate are set, and both ends of the guide plate are embedded in the guide groove, so that the guide plate can move along the height direction of the guide groove after being subjected to force, thereby guiding the guide plate and the annular cutter installed under the guide plate.
[0011] Optionally, the driving assembly includes a cylinder fixedly connected to the horizontal section of the bracket, a piston rod is installed on the cylinder, and an end of the piston rod away from the cylinder passes through the bracket and is fixedly connected to the middle section of the guide plate.
[0012] By adopting the above technical solution, when cutting, the cylinder is started to push the piston rod to extend, thereby pushing the guide plate to slide down along the guide groove, thereby pushing the annular cutter to move down for cutting.
[0013] Optionally, the annular cutter is set according to the shape and size of the seat cover to be cut, and a cutting groove corresponding to the cutting edge of the annular cutter is provided on the base below the annular cutter.
[0014] By adopting the above technical scheme, the shape and size of the annular cutter are set according to the seat cover to be cut, so that annular cutters of different shapes can be designed for cutting according to the needs. The cutting groove corresponding to the blade of the annular cutter allows the annular cutter to be embedded in the cutting groove during the cutting process, so as to facilitate the cutting of the fabric at the bottom layer.
[0015] Optionally, the outer pressure ring and the inner pressure ring are both annular in structure, and the sides of the outer pressure ring and the inner pressure ring close to the annular cutter are tightly fitted to the annular cutter.
[0016] By adopting the above technical solution, the outer pressure ring and the inner pressure ring can fit closely with the fabrics on both sides of the annular cutter, and the deformation of the fabrics when squeezed by the annular cutter can be avoided as much as possible, resulting in deviation in the size of the cut fabrics.
[0017] Optionally, the elastic connecting member includes a sliding rod whose bottom end is fixedly connected to the top of the outer pressure ring and the inner pressure ring, a sliding tube is sleeved on the top of the sliding rod to be slidably connected to the sliding rod, and a spring is embedded in the inner cavity of the sliding tube, the spring having one end fixedly connected to the end of the sliding rod and the other end fixedly connected to the inner wall of the sliding tube.
[0018] By adopting the above technical solution, when the outer pressure ring and the inner pressure ring are supported by the fabric and move upward along the sliding hole, the sliding rod will be pushed to move into the inner cavity of the sliding tube and squeeze the spring to contract. The contracted spring pushes the outer pressure ring and the inner pressure ring downward in the opposite direction under the action of its own elastic force, and the fabrics on both sides of the annular cutter are tightly pressed onto the base.
[0019] Optionally, when the spring is in an extended state, the bottom heights of the outer pressure ring and the inner pressure ring are lower than the bottom height of the annular cutter.
[0020] By adopting the above technical scheme, when the annular cutter moves downward for cutting, the bottom of the outer pressure ring and the inner pressure ring first fit against the fabric to squeeze and fix the fabric, and at the same time, as the annular cutter moves downward, the compression amount of the spring gradually increases, so that the force of the spring pushing the outer pressure ring and the inner pressure ring gradually increases, thereby making the outer pressure ring and the inner pressure ring fix the fabric more and more stably.
[0021] In summary, the beneficial effects of this application are as follows:
[0022] The present application adopts the coordination setting between the structures such as the annular cutter, the outer pressure ring, the inner pressure ring and the spring. When the annular cutter moves down for cutting, the outer pressure ring and the inner pressure ring first fit with the fabric. As the annular cutter continues to move down, the outer pressure ring and the inner pressure ring move up under the support of the fabric and squeeze the spring to contract. The spring then pushes the outer pressure ring and the inner pressure ring in the opposite direction under the action of its own elastic force to press the fabric to prevent the fabric from deforming during the cutting process. This avoids the problem that the existing cutting device cannot press the cutting position during the cutting process, the fabric is easily deformed due to the squeezing of the cutting knife during the cutting process, resulting in deviation in the cutting size, which seriously affects the cutting quality.

DETAILED DESCRIPTION
[0027] The following is combined with Figure 1-3 This application is described in further detail.
[0028] See also Figure 1-3 A preparation device for a rebound seat cover includes a base 1 with a bracket 2 fixedly connected to the upper surface, both ends of the base 1 extend outward to form a mounting plate, and bolts are passed through the mounting plate, so that a user can install the base 1 on an external frame through the mounting plate and the bolts.
[0029] A guide assembly is slidably connected in the inner cavity of the bracket 2, and a driving assembly for pushing the guide assembly to move is installed on the top of the bracket 2. A connecting seat 7 is installed on the guide assembly, and a ring-shaped cutter 8 is fixedly connected to the lower surface of the connecting seat 7. When the ring-shaped cutter 8 installed on the connecting seat 7 is pushed downward by the driving assembly to cut the fabric, it can be guided by the guide assembly to avoid deviation during the cutting process as much as possible.
[0030] An anti-deformation structure is slidably connected to the annular cutter 8, and the anti-deformation structure includes a plurality of sliding holes 10 vertically opened on the side wall of the annular cutter 8, and also includes an outer pressure ring 11 sleeved on the outer surface of the annular cutter 8 and an inner pressure ring 12 embedded in the inner cavity of the annular cutter 8. The top ends of the outer pressure ring 11 and the inner pressure ring 12 are fixedly connected by a connecting plate 13 passing through the sliding hole 10, so that after the inner pressure ring 12 and the outer pressure ring 11 are squeezed, the connecting plate 13 can be pushed to move upward along the sliding hole 10 to adjust the bottom height of the inner pressure ring 12 and the outer pressure ring 11.
[0031] The tops of the outer pressure ring 11 and the inner pressure ring 12 are fixedly connected to the connecting seat 7 via elastic connectors, and when the elastic connectors are in an extended state, the bottom heights of the outer pressure ring 11 and the inner pressure ring 12 are lower than the bottom height of the annular cutter 8 .
[0032] Reference Figure 1The bracket 2 is in a U-shaped structure, and the guide assembly includes a guide groove 3 provided on the inner wall of the two vertical sections of the bracket 2 and a guide plate 4 provided inside the bracket 2, with both ends extending into the guide groove 3 and slidably connected to the side wall of the bracket 2 through the guide groove 3, and a connecting seat 7 is fixedly connected to the lower surface of the guide plate 4. The guide groove 3 and the guide plate 4 are provided, and both ends of the guide plate 4 are embedded in the guide groove 3, so that the guide plate 4 can move along the height direction of the guide groove 3 after being subjected to force, and guide the guide plate 4 and the annular cutter 8 installed below the guide plate 4.
[0033] Reference Figure 1 The driving assembly includes a cylinder 5 fixedly connected to the horizontal section of the bracket 2, a piston rod 6 is installed on the cylinder 5, and the end of the piston rod 6 away from the cylinder 5 passes through the bracket 2 and is fixedly connected to the middle section of the guide plate 4. When cutting, the cylinder 5 is started to push the piston rod 6 to extend, thereby pushing the guide plate 4 to slide down along the guide groove 3, thereby pushing the annular cutter 8 to move down for cutting.
[0034] Reference Figure 2 The annular cutter 8 is set according to the shape and size of the seat cover to be cut, and a cutting groove 9 corresponding to the blade of the annular cutter 8 is provided on the base 1 below the annular cutter 8. The shape and size of the annular cutter 8 are set according to the seat cover to be cut, so that the annular cutter 8 of different shapes can be designed for cutting according to the needs. The cutting groove 9 corresponding to the blade of the annular cutter 8 allows the annular cutter 8 to be embedded in the cutting groove 9 during the cutting process, so that the fabric at the bottom layer can be cut conveniently.
[0035] Reference Figure 3 The outer pressure ring 11 and the inner pressure ring 12 are both annular structures, and the outer pressure ring 11 and the inner pressure ring 12 are closely fitted with the annular cutter 8 on one side thereof. The outer pressure ring 11 and the inner pressure ring 12 can be closely fitted with the fabrics on both sides of the annular cutter 8, and the deformation of the fabrics when being squeezed by the annular cutter 8 is avoided as much as possible, resulting in deviation in the size of the cut fabrics.
[0036] Reference Figure 1 The elastic connecting member includes a slide bar 14 whose bottom end is fixedly connected to the top of the outer pressure ring 11 and the inner pressure ring 12, and a slide tube 15 is sleeved on the top of the slide bar 14 to be slidably connected to the slide bar 14. A spring 16 is embedded in the inner cavity of the slide tube 15, one end of which is fixedly connected to the end of the slide bar 14 and the other end is fixedly connected to the inner wall of the slide tube 15. When the outer pressure ring 11 and the inner pressure ring 12 are supported by the fabric and move upward along the slide hole 10, the slide bar 14 will be pushed to move into the inner cavity of the slide tube 15, and the spring 16 will be squeezed to contract. The contracted spring 16 pushes the outer pressure ring 11 and the inner pressure ring 12 downward in the opposite direction under the action of its own elastic force, and the fabrics on both sides of the annular cutter 8 are tightly pressed onto the base 1.
[0037] Reference Figure 3When the spring 16 is in an extended state, the bottom heights of the outer pressure ring 11 and the inner pressure ring 12 are lower than the bottom height of the annular cutter 8. When the annular cutter 8 moves downward for cutting, the bottoms of the outer pressure ring 11 and the inner pressure ring 12 first fit the fabric to squeeze and fix the fabric. At the same time, as the annular cutter 8 moves downward, the compression amount of the spring 16 gradually increases, so that the force of the spring 16 pushing the outer pressure ring 11 and the inner pressure ring 12 gradually increases, so that the outer pressure ring 11 and the inner pressure ring 12 fix the fabric more and more stably.
[0038] The implementation principle of the present application is as follows: when in use, the user first places the fabric to be cut on the base 1, and then starts the cylinder 5 to push the guide plate 4 to slide down along the guide groove 3, driving the annular cutter 8 installed on the connecting seat 7 to move downward. Since the bottom heights of the outer pressure ring 11 and the inner pressure ring 12 on the inner and outer sides of the annular cutter 8 are lower than the bottom height of the annular cutter 8, the outer pressure ring 11 and the inner pressure ring 12 first fit with the fabric. As the annular cutter 8 continues to move downward, the outer pressure ring 11 and the inner pressure ring 12 drive the connecting plate 13 to move up along the sliding hole 10 under the support of the fabric, and the squeezing spring 16 contracts, and the spring 16 pushes the outer pressure ring 11 and the inner pressure ring 12 in the opposite direction under the action of its own elastic force to press the fabric to prevent the fabric from deforming during the cutting process, and tries to avoid the problem that the existing cutting device cannot press the cutting position during the cutting process, and the fabric is easily deformed due to the squeezing of the cutting knife during the cutting process, resulting in deviation in the cutting size, which seriously affects the cutting quality.
