[0002] A sofa cover is an outer cover for a sofa, meaning an item that covers the surface of a sofa. Generally, sofa covers come in two types: removable and non-removable.

[0003] Chinese Patent Application No. 202420720325.6 discloses a sofa cover cutting device, including a fixed frame fixedly connected to the top surface of a cutting table. A cutting adjustment device is located below the fixed frame. The cutting adjustment device includes a toothed disc with a circular groove on its top surface. An adjusting locking device is slidably connected to the top surface of the circular groove. A baffle is inserted into the outer wall of the toothed disc, and a cutting adjustment device for cutting fabric is located on the bottom surface of the toothed disc. This invention provides a cutting adjustment device below the fixed frame, wherein the cutting adjustment device includes a toothed disc, and an adjusting locking device is rotatably connected to the outer wall of the toothed disc. By adjusting the locking device in cooperation with the baffle, the rotation angle of the cutting adjustment device can be controlled. This allows the cutting adjustment device to cut different fan-shaped shapes of fabric according to requirements, thereby increasing the practicality of the device.

[0004] In the aforementioned patent, the pressing plate and the N-shaped plate are connected by a second spring. During the subsequent cutting process of the sofa cover, the second spring is prone to deformation under force, which in turn causes the pressing plate to move, affecting the pressing effect of the pressing plate on the sofa cover and thus affecting the cutting effect of the sofa cover. In addition, after the sofa cover is laid flat on the cutting table, if the sofa cover is long, it is easy for it to drag on the ground, which can easily cause the sofa cover to become contaminated.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a fixing component. After the pressing mechanism presses the two ends of the sofa cover, the pressing block moves along the shrink groove. The movement of the pressing block causes the connecting spring to stretch. Then, the plug screw is rotated into the two threaded holes. Then, the motor is started, and the motor drives the screw to rotate, which in turn drives the threaded block to move. The movement of the threaded block drives the moving block to move, and the movement of the moving block drives the pressing block to move. When the pressing block moves and fits against the top of the pressing mechanism component, the motor is stopped. The pressing block can fix the component of the pressing mechanism, ensuring the stability of the pressing mechanism component and thus ensuring the pressing and fixing effect of the pressing mechanism on the sofa cover.

[0014] 2. This utility model features a placement component. The sofa cover is laid flat on the cutting table, with one end of the sofa cover flush with the other end of the cutting table. A clamping mechanism is then used to press and fix the sofa cover in place. The excess portion of the other end of the sofa cover is then attached to the placement rod. When the sofa cover to be cut is rolled up, the threaded cylinder is removed from the fixing screw by rotating it. The top plate is then moved up, and the placement rod is removed from the placement plate. The placement rod is then inserted into the rolled sofa cover, and the placement rod is placed back onto the placement plate. The top plate is then moved to fit the placement plate, and the fixing screw passes through the connecting ear through the through hole. The threaded cylinder is then rotated and screwed onto the fixing screw. This facilitates the placement of the sofa cover, prevents the sofa cover from dragging on the ground due to its excessive length, and thus avoids soiling the sofa cover. Attached Figure Description

[0021] 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.

[0022] Example 1

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a sofa cover cutting device, including a cutting table 3, a pressing mechanism 1 is provided at both ends of the upper part of the cutting table 3, a cutting mechanism 4 is provided above the cutting table 3 and between the two pressing mechanisms 1, a placement component 5 is provided on the side wall of the cutting table 3, and a fixing component 2 is provided above the pressing mechanism 1.

[0024] Specifically, the fixing component 2 includes a side block 21, a threaded block 22, a moving cavity 23, a motor 24, a screw 25, a moving block 26, and a moving retractable component 27. The side block 21 is fixedly connected to the top of the pressing mechanism 1. The moving cavity 23 is formed on the side wall of the side block 21. The motor 24 is fixedly connected to the top of the side block 21. The screw 25 is fixedly connected to the output end of the motor 24 and located inside the moving cavity 23. The threaded block 22 is threadedly connected to the outer side wall of the screw 25. The moving block 26 is fixedly connected to the side wall of the threaded block 22. The moving retractable component 27 is provided inside the moving block 26.

[0025] By adopting the above technical solution, after the pressing mechanism 1 presses the sofa cover, the movable shrinking part 27 is moved outward from the moving block 26. Then, the motor 24 is started, and the motor 24 drives the screw 25 to rotate, which in turn drives the threaded block 22 to move. The movement of the threaded block 22 drives the moving block 26 to move, and the movement of the moving block 26 drives the movable shrinking part 27 to move. When the movable shrinking part 27 moves and fits against the top of the pressing mechanism 1, the motor 24 is stopped. The movable shrinking part 27 can be used to fix the parts of the pressing mechanism 1, ensuring the stability of the pressing mechanism 1 and thus ensuring the pressing and fixing effect of the pressing mechanism 1 on the sofa cover.

[0026] Specifically, guide posts are fixedly connected inside the movable cavity 23 and on both sides of the screw 25, and guide holes are provided on the threaded block 22 at the positions corresponding to the guide posts.

[0027] By adopting the above technical solution, the guide post and guide hole can provide guidance for the movement of the threaded block 22, improve the stability of the movement of the threaded block 22, and prevent the threaded block 22 from rotating with the rotation of the screw 25.

[0028] Specifically, the movable shrinking component 27 includes a shrinking groove 271, a pressure block 272, a connecting screw 273, a connecting spring 274, and a threaded hole 275. The movable block 26 has a shrinking groove 271 inside, and the pressure block 272 is slidably connected inside the shrinking groove 271. The connecting spring 274 is fixedly connected between the movable block 26 and the pressure block 272. Both the movable block 26 and the pressure block 272 have threaded holes 275, and the connecting screw 273 is threadedly connected between the movable block 26 and the pressure block 272.

[0029] By adopting the above technical solution, the pressure block 272 moves along the shrinkage groove 271. The movement of the pressure block 272 causes the connecting spring 274 to stretch. Then, the plug screw 273 is rotated and screwed into the two threaded holes 275. The plug screw 273 can be used to plug and fix the pressure block 272 and the moving block 26, ensuring the pressing effect of the pressure block 272 on the pressing mechanism 1, while avoiding the pressure block 272 affecting the normal use of the pressing mechanism 1.

[0030] Specifically, a limit slider is fixedly connected to one end of the pressure block 272, and a limit groove is formed on the inner side wall of the moving block 26.

[0031] By adopting the above technical solution, the pressure block 272 moves and drives the limiting slider to move along the limiting groove. When the limiting slider moves and fits against the side wall of the limiting groove, the limiting slider is blocked and stops moving, thereby preventing the pressure block 272 from continuing to move and avoiding the pressure block 272 from moving away from the moving block 26.

[0032] In this embodiment, the sofa cover is laid flat on the cutting table 3, and the pressing mechanism 1 is used to press the two ends of the sofa cover. Then, the pressing block 272 is moved along the shrink groove 271. The movement of the pressing block 272 causes the connecting spring 274 to stretch. Then, the plug screw 273 is rotated and screwed into the two threaded holes 275. Then, the motor 24 is started, and the motor 24 drives the screw 25 to rotate, which in turn drives the threaded block 22 to move. The movement of the threaded block 22 drives the moving block 26 to move, and the movement of the moving block 26 drives the pressing block 272 to move. When the pressing block 272 moves and fits against the top of the pressing mechanism 1 component, the motor 24 is stopped. The pressing block 272 can be used to fix the component of the pressing mechanism 1, ensuring the stability of the pressing mechanism 1 component and thus ensuring the pressing and fixing effect of the pressing mechanism 1 on the sofa cover. Then, the cutting mechanism 4 is used to cut the sofa cover.

Placement plates 51 are fixedly connected to both sides of one end of the cutting table 3. A placement rod 52 is disposed inside the placement plate 51. A top plate 55 is disposed above the placement plate 51. Arc-shaped grooves 56 are formed on the sides of the placement plate 51 and the top plate 55 that are close to each other. Fixing screws 53 are fixedly connected to both ends of the upper part of the placement plate 51. Connecting lugs 58 are fixedly connected to both ends of the top plate 55. Through holes 57 are formed on the connecting lugs 58 at positions corresponding to the fixing screws 53. A threaded cylinder 54 is threadedly connected to the outer wall of the fixing screw 53.

[0035] In this embodiment, the sofa cover is laid flat on the cutting table 3, with one end of the sofa cover flush with one end of the cutting table 3. The sofa cover is then pressed and fixed using the clamping mechanism 1. The excess part of the other end of the sofa cover is then attached to the placement rod 52. When the sofa cover to be cut is rolled up, the threaded cylinder 54 is removed from the fixing screw 53 by rotating it. The top plate 55 is then moved up, and the placement rod 52 is removed from the placement plate 51. The placement rod 52 is then inserted into the rolled-up sofa cover. The placement rod 52 is then placed on the placement plate 51, and the top plate 55 is moved to fit against the placement plate 51. The fixing screw 53 then passes through the connecting ear 58 through the through hole 57. The threaded cylinder 54 is then rotated and screwed onto the fixing screw 53. This facilitates the placement of the sofa cover, prevents the sofa cover from dragging on the ground due to its excessive length, and thus avoids contamination of the sofa cover.

[0036] In this utility model, the motor 24 is a previously disclosed technology, and the selected model is Y2100L2.

[0037] The structure and principle of the pressing mechanism 1, which consists of an N-shaped plate, a limiting groove, a second spring, a pressing plate, and a pull ring, have been disclosed in a sofa cover cutting device disclosed in Chinese patent application number 202420720325.6. Its working principle is as follows: N-shaped plates are fixedly connected to both ends of the upper part of the cutting table 3. Limiting grooves are opened on both side walls of the N-shaped plate. A pressing plate is slidably connected between the two limiting grooves. A second spring is connected between the pressing plate and the N-shaped plate. A pull ring is provided on the top surface of the N-shaped plate. The bottom end of the pull ring is fixedly connected to the top surface of the pressing plate. Under normal conditions, the second spring can squeeze the pressing plate. The teeth at the bottom of the pressing plate can fix the fabric.

[0038] The structure and principle of the cutting mechanism 4, which consists of a fixed frame, an electric slide rail, an electric telescopic rod, a load-bearing frame, a drive motor, a toothed disc, a circular groove, a moving frame, a fixed rod, a rotating rod, a gear, a slide groove, a pull plate, a sector toothed plate, a first spring, a baffle, a threaded rod, a movable block, a cutting blade, and a twisting plate, have been disclosed in a sofa cover cutting device disclosed in Chinese Patent Application No. 202420720325.6. Its working principle is as follows: A fixed frame is fixedly connected to the top surface of the cutting table 3; an electric slide rail is fixedly connected to the top of the inner wall of the fixed frame; an electric telescopic rod is fixedly connected to the bottom end of the electric slide rail; a load-bearing frame is fixedly connected to the output end of the electric telescopic rod; a drive motor is fixedly connected inside the load-bearing frame 5; a connecting plate is fixedly connected to the bottom of the load-bearing frame; a toothed disc is fixedly connected to the bottom end of the connecting plate; and a threaded rod is rotatably connected to the output end of the drive motor through the toothed disc. The surface of the threaded rod is threaded... A movable block is attached, with a cutting blade fixedly connected to its bottom surface. The top surface of the movable block abuts against the bottom surface of the toothed disc. A rotating plate is fixedly connected to the top of the threaded rod. A circular groove is formed on the top surface of the toothed disc, and a fixed rod is slidably connected inside the groove. A movable frame is fixedly connected to one end of the fixed rod. A rotating rod is rotatably connected to the inner wall of the movable frame. A gear is fixedly connected to the surface of the rotating rod, and the teeth of the gear mesh with the teeth of the outer wall of the toothed disc. A baffle is inserted into the outer wall of the toothed disc. In use, the electric slide rail is started to move the electric telescopic rod to the corresponding position. Then, according to the desired shape of the fabric, the pull plate is pulled to separate the fan-shaped toothed plate from the gear. Then, the movable frame is pushed, and the rotating plate is turned to drive the threaded rod to rotate. The rotation of the threaded rod drives the movable block to move, and the movable block drives the cutting blade to move, thereby controlling the radius of the fan shape. Finally, the drive motor is started to drive the cutting blade to rotate and cut.

[0039] The working principle and usage process of this utility model are as follows: The sofa cover is laid flat on the cutting table 3, with one end of the sofa cover flush with one end of the cutting table 3. The pressing mechanism 1 then presses and fixes the sofa cover. The excess portion of the other end of the sofa cover is then attached to the placement rod 52. When the sofa cover to be cut is rolled up, the threaded cylinder 54 is removed from the fixing screw 53 by rotating it. The top plate 55 is then moved upwards, and the placement rod 52 is removed from the placement plate 51 and inserted into the rolled-up sofa cover. The placement rod 52 is then placed on the placement plate 51, and the top plate 55 is moved to fit against the placement plate 51. The fixing screw 53 then passes through the connecting ear 58 via the through hole 57. The threaded cylinder 54 is then rotated and screwed onto the fixing screw 53, facilitating the placement of the sofa cover and preventing the sofa cover from being over-rolled. To prevent the sofa cover from getting dirty, the pressure block 272 moves along the shrink groove 271. The movement of the pressure block 272 stretches the connecting spring 274. Then, the insertion screw 273 is rotated and screwed into the two threaded holes 275. Then, the motor 24 is started, which drives the screw 25 to rotate, which in turn drives the threaded block 22 to move. The movement of the threaded block 22 drives the moving block 26 to move, which in turn drives the pressure block 272 to move. When the pressure block 272 moves and fits against the top of the pressing mechanism 1 component, the motor 24 is stopped. The pressure block 272 can be used to fix the component of the pressing mechanism 1, ensuring the stability of the pressing mechanism 1 component and thus ensuring the pressing and fixing effect of the pressing mechanism 1 on the sofa cover. Then, the cutting mechanism 4 is used to cut the sofa cover.
