DETAILED DESCRIPTION

[0028] The following will be combined with the attached Figure 1-10 The utility model is further described with examples.

[0029] Embodiment 1: Due to the existing fabric cutting device, after cutting the fabric with wrinkles, the fabric is a cloth, and the fabric will deviate from the preset fabric shape. To solve the above problem, refer to Figure 1-10 The present embodiment provides a fabric cutting device, including a transmission component, a pressing component, a cutting head 13, and a processing frame 14. The top surface of the processing frame 14 is provided with a processing table 15, and the processing table 15 is used to receive the fabric. The cutting head 13 slides on the upper side of the processing table 15, so as to cut the fabric on the processing table 15. The transmission component is used to drive the fabric to slide on the processing table 15. The pressing component includes a connecting member 17, a pressing motor 18, and a pressing roller 19 for contacting the fabric. The connecting member 17 is connected to the processing frame 14, and the fixed end of the pressing motor 18 is connected to the connecting member. The connecting piece 17 is fixedly connected, the rotating end of the pressing motor 18 is axially connected to the pressing roller 19, the axial direction of the pressing roller 19 is arranged parallel to the transmission direction of the fabric, the pressing roller 19 abuts against the side of the fabric, the fabric is placed on the processing table 15, and then the pressing roller 19 abuts against the fabric, and at the same time the pressing motor 18 drives the pressing roller 19 to rotate, the pressing roller 19 drives the fabric into a tensioned state, thereby reducing the wrinkles of the fabric, and the cutting head 13 then cuts the fabric according to a preset shape, reducing the influence of the wrinkles on the fabric on the shape of the fabric cutting.

[0030] It should be noted that the pressing motor 18 drives the pressing roller 19 to rotate from the center of the fabric toward the two sides of the fabric.

[0031] When the pressing roller 19 is in contact with the fabric, there is a risk of low stability in the pressing force of the pressing roller 19 on the fabric. If the pressing force of the pressing roller 19 on the fabric is low, the pressing roller 19 cannot stably tension the fabric, thereby causing the wrinkles of the fabric to affect the shearing of the shearing head. To solve the above problem, the pressing assembly of this embodiment includes an elastic telescopic rod 20, the axial direction of the elastic telescopic rod 20 is vertically arranged, and the two ends of the elastic telescopic rod 20 are connected between the connecting piece 17 and the fixed end of the pressing motor 18. When the pressing roller 19 is in contact with the fabric, the elastic telescopic rod 20 provides a downward force to the pressing roller 19 through the pressing motor 18, thereby increasing the force between the pressing roller 19 and the fabric, and improving the stability of the tensioning of the fabric by the pressing roller 19.

[0032] After a section of fabric is cut, it is necessary to drive a new unprocessed fabric section into the processing table 15. If the pressing roller 19 is continuously in contact with the processing table 15, it will affect the smoothness of the fabric entering the processing table 15. To solve the above problem, the pressing assembly of this embodiment includes a lifting motor 21 and a cylindrical lifting screw rod 22. The processing frame 14 is connected with a nut member 23 with a thread, that is, the nut member 23 is a nut. The lifting screw rod 22 and the nut member 23 are vertically slidably connected by threads. The bottom surface protrusion of the connecting member 17 is provided with an inner round bar 25, and the annular wall of the inner round bar 25 is provided with an annular groove 26. The inner annular wall protrusion of the lifting screw rod 22 is provided with an annular convexity 27. The annular convexity 27 is assembled in the annular groove 26 and is a rotatable assembly. The fixed end of the lifting motor 21 is connected to the processing frame 14. The work frame 14 is connected, and the rotating end of the lifting motor 21 is connected to the lifting screw rod 22. The rotating end of the lifting motor 21 drives the lifting screw rod 22 to rotate. The rotating lifting screw rod 22 is connected to the nut member 23 through a threaded connection to slide vertically relative to the nut member 23, and the inner round bar 25 is also moved vertically by the abutment between the annular groove 26 and the annular protrusion 27. However, the inner round bar 25 does not rotate with the action of the pressure roller 19, so that the connecting member 17 connected to the inner round bar 25 slides vertically, and then the connecting member 17 drives the pressure roller 19 to slide vertically. Through the above arrangement, when it is necessary to drive the fabric, the lifting motor 21 drives the pressure roller 19 to rise, making way for the sliding of the fabric, thereby realizing the sliding of the fabric on the processing table 15 and improving the stability of the fabric movement.

[0033] In order to further improve the stability of the pressure roller 19 during vertical sliding, the bottom surface protrusion of the connecting member 17 of this embodiment is provided with a vertically extending guide strip 28, and the side of the processing frame 14 is connected to a guide member 29, and the guide member 29 is provided with a vertically extending guide hole 30. The guide strips 28 are vertically slidably connected to the guide strips 28. When the lifting motor 21 drives the pressure roller 19 to slide vertically, the sliding connection between the guide strip 28 and the guide member 29 guides the vertical sliding of the connecting member 17, and then also guides the pressure roller 19, thereby improving the sliding stability of the pressure roller 19.

[0034] The pressing rollers 19 are provided in two groups, and the two groups of pressing rollers 19 are respectively located on two sides of the processing table 15 .

[0035] In order to correspond to the table surface of the processing table 15, the pressure roller 19 is set in a long strip shape, so in order to improve stability, the pressure roller 19 needs to be driven from both ends of the pressure roller 19. In order to save the cost of the equipment driving components, the new pressure component of this embodiment includes a driving wheel 31, a driven wheel 32, and a transmission belt 33. The driven wheel 32 is interference-connected with the outer ring surface of the lifting screw rod 22. The driving wheel 31 is connected to the rotating end of the lifting motor 21. The transmission belt 33 is sleeved on the driving wheel 31 and the driven wheel 32, and is used to drive the lifting screw rod 22 to rotate around the axis. The two sets of lifting screws The rods 22 are respectively connected to the two ends of the pressure roller 19, and the two groups of driven wheels 32 are respectively connected to the two groups of lifting screw rods 22. The rotating end of the lifting motor 21 drives the driving wheel 31 to rotate, and the rotating driving wheel 31 drives the two groups of driven wheels 32 to rotate synchronously through the transmission belt 33. The driven wheel 32 drives the lifting screw rod 22 to rotate, so that the lifting screw rod 22 can drive the pressure roller 19 to move vertically. By setting the transmission belt 33, the pressure roller 19 can be driven from both ends of the pressure roller 19, thereby improving the stability of the vertical sliding of the pressure roller 19.

[0036] When the driving belt 33 drives the driven wheel 32, since the driven wheel 32 and the lifting screw rod 22 are in interference connection, when the lifting screw rod 22 slides vertically, the driven wheel 32 will also slide vertically, and then the driven wheel 32 will drive the driving belt 33 to slide vertically. In order to reduce the vertical sliding displacement of the driving belt 33 being too large and causing the driving belt 33 to be pulled and damaged, in order to solve the above problem, the processing table 15 of this embodiment is provided with a limiting hole 34 for limiting the vertical displacement of the driving belt 33. The axial direction of the limiting hole 34 is arranged parallel to the axial direction of the pressure roller 19, and the driving belt 33 is passed through the limiting hole 34. When the lifting screw rod 22 slides vertically, the driven wheel 32 will also slide vertically and thus drive the driving belt 33 to slide vertically. By setting the limiting hole 34, the vertically sliding driving belt 33 will abut against the inner hole wall of the limiting hole 34 to limit the vertical displacement of the driving belt 33, thereby reducing the risk of the driving belt 33 being damaged by being pulled.

[0037] In order to prevent the lifting screw 22 from being separated from the equipment due to excessive vertical sliding, thereby causing the lifting screw 22 to lose its driving function, the outer ring wall of the lifting screw 22 of this embodiment is fixedly connected with two sets of limit rings 44, and the vertical distance between the two sets of limit rings 44 is set equal to the vertical sliding distance of the pressure roller 19, so that the lifting screw 22 can only slide between the two limit rings 44, thereby avoiding the possibility of the lifting screw 22 being separated from the equipment due to excessive sliding.

[0038] Furthermore, the ratio of the vertical dimension of the limiting hole 34 to the vertical dimension of the transmission belt 33 is 1.5:1. Through the above arrangement, the transmission belt 33 can move vertically synchronously with the driven wheel 32 within a certain range, but the transmission belt 33 will not be excessively stretched, thereby reducing the relative friction between the transmission belt 33 and the driven wheel 32 and reducing the wear on the transmission belt 33.

[0039] Specifically, the connecting member 17 is a plate-shaped configuration, the inner circular bar 25 , the guide bar 28 , and the elastic telescopic rod 20 are all connected to the bottom surface of the connecting member 17 , and the lifting screw 22 is located at the lower side of the connecting member 17 .

[0040] The transmission assembly of this embodiment includes a rotating roller 35, a support frame 36, and a winding motor 37. The support frame 36 is vertically fixedly connected to the processing frame 14. The fixed end of the winding motor 37 is connected to the processing frame 14, and the rotating end of the winding motor 37 is connected to the rotating roller 35. The axial direction of the rotating roller 35 is perpendicular to the transmission direction of the fabric. When the fabric on the processing table 15 is processed, the winding motor 37 drives the rotating roller 35 to rotate and winds up the processed fabric, thereby driving the unprocessed fabric into the processing table 15, so that the fabric can be processed by the equipment.

[0041] Embodiment 2: The difference between this embodiment and embodiment 1 is the pressing assembly. The pressing assembly of this embodiment includes a lifting cylinder 47, a connecting piece 17, an elastic telescopic rod 20, a pressing roller 19, and a pressing motor 18. The fixed end of the lifting cylinder 47 is connected to the processing frame 14, and the movable end of the lifting cylinder 47 is connected to the connecting piece 17. One end of the elastic telescopic rod 20 is connected to the bottom wall of the connecting piece 17, and the other end of the elastic telescopic rod 20 is connected to the fixed end of the pressing motor 18. The rotating end of the pressing motor 18 is axially connected to the pressing roller 19. When the equipment needs to drive the fabric, the movable end of the lifting cylinder 47 drives the pressing roller 19 to rise, and then drives the fabric to slide, so that the unprocessed fabric enters the processing table 15, and the movable end of the lifting cylinder 47 drives the pressing roller 19 to slide downward, so that the pressing roller 19 contacts the fabric, and the pressing motor 18 drives the pressing roller 19 to rotate, thereby tensioning the fabric, and the shearing head cuts the fabric.

[0042] The pressure assembly of this embodiment also includes a linkage plate 45 and a connecting strip 46. The movable end of the lifting cylinder 47, the linkage plate 45, the connecting strip 46, and the connecting piece 17 are connected in sequence. Specifically, the linkage plate 45 is connected to the movable end of the lifting cylinder 47, the lower end of the connecting strip 46 is connected to the linkage plate 45, and the upper end of the connecting strip 46 is connected to the connecting piece 17, so that the movable end of the lifting cylinder 47 drives the pressure roller 19 to slide vertically through the linkage plate 45 and the connecting strip 46.

[0043] Specifically, two groups of elastic telescopic rods 20 , the connecting member 17 , and the connecting strip 46 are respectively connected to two ends of a group of pressing rollers 19 , and the pressing motor 18 is connected to one end of the pressing roller 19 .

[0044] When the lifting cylinder 47 drives the pressure roller 19 to slide, in order to improve the sliding stability of the connecting strip 46, a sliding hole 42 is opened on the top wall of the processing frame 14 of this embodiment, and the connecting strip 46 and the sliding hole 42 are sliding and adaptively arranged. When the lifting cylinder 47 drives the pressure roller 19 to slide, due to the sliding connection between the sliding hole 42 and the connecting strip 46, the sliding hole 42 limits the sliding of the connecting strip 46, thereby improving the stability of the connecting strip 46 when sliding vertically, thereby improving the stability of the pressure roller 19 when sliding vertically.

[0045] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
