Description

Technical Field

[0001] This application relates to the field of fabric cutting technology, and in particular to a cutting device for canvas production. Background Technology

[0002] The home textile industry is currently very large, resulting in a wide variety of home textile products and demand for fabrics of various specifications. The industry's conventional practice is to cut the whole roll of fabric by hand. This method usually requires high craftsmanship, and hand-cut fabrics are prone to having rough edges and snags on the sides.

[0003] A search revealed that CN212741976U discloses a fabric cutting machine. One clamping seat can be pulled to move a slider within a groove. Through the setting of a support rod and a limiting block, another slider is moved within the groove to adjust the distance between the two clamping seats to a suitable level. Then, the handle is released, and a core cylinder is placed on a rubber roller to fix the fabric core. Finally, a second motor is started to drive the rubber roller to rotate, which in turn drives the fabric core to rotate. A third motor is started to drive the lead screw to rotate, which in turn drives the cutting table to slide along the length of the fabric core, moving the cutting disc to a suitable position for cutting at the next position of the fabric core. This eliminates the need for personnel to remove the fabric core and re-clamp it.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] This device selects the cutting position by freely moving the cutting disc, thus achieving the cutting effect of fabric for different widths. However, in actual use, continuous equidistant cutting will cause the cut strips of fabric to scatter on both sides of the base, making them inconvenient to collect. Utility Model Content

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a slitting device for canvas production. (Refer to...) Figures 1 to 5The canvas production slitting device includes a cutting table 1, a fixed frame 2, a linear motor 3, a connecting frame 4, a cutting machine body 5, an auxiliary tensioning assembly 6, a fabric strip sorting assembly 7, and an auxiliary unwinding assembly 8. The fixed frame 2 is fixedly connected to the top of the cutting table 1. The linear motor 3 is installed on the upper end of the fixed frame 2. The connecting frame 4 is installed on the moving surface of the linear motor 3. The cutting machine body 5 is threadedly connected to the outside of the connecting frame 4. The auxiliary tensioning assembly 6 is fixedly connected to one side of the fixed frame 2. The fabric strip sorting assembly 7 is slidably connected to one side of the top of the cutting table 1. The auxiliary unwinding assembly 8 is fixedly connected to the other side of the cutting table 1.

[0038] The auxiliary unwinding assembly 8 is used to wind up the fabric to be cut. The cutting table 1 is used to support the canvas and keep the fabric horizontal. The fixing frame 2, together with the linear motor 3, is used to drive the connecting frame 4 and the cutting machine body 5 to move stably along the Y-axis. The cutting machine body 5 is used to cut fabric of different sizes longitudinally. The auxiliary tensioning assembly 6, together with the fabric strip sorting assembly 7, is used to keep the fabric in a tensioned state before cutting. The fabric strip sorting assembly 7 is used to move the cut fabric strips to the outside of the cutting table 1 and collect them.

[0039] The fabric strip sorting assembly 7 includes a push cylinder 71, a sliding seat 72, a support frame 73, a hydraulic cylinder 74, and a pusher plate 75. The output end of the push cylinder 71 is fixedly connected to the middle of one side of the sliding seat 72. The top surface of the sliding seat 72 is fixedly connected to the bottom of the support frame 73. The hydraulic cylinder 74 is installed at the middle of the top of the support frame 73. The pusher plate 75 is installed below the output end of the hydraulic cylinder 74 and is tightly fitted to one end of the fabric strip.

[0040] The auxiliary tensioning assembly 6 includes a positioning support 61, a hydraulic cylinder 62, and an auxiliary tensioning plate 63. The positioning support 61 is fixedly connected to the outside of the fixing frame 2. The hydraulic cylinder 62 is installed on the top of the positioning support 61. The auxiliary tensioning plate 63 is installed below the output end of the hydraulic cylinder 62 and is used to clamp and assist in tensioning the fabric.

[0041] The auxiliary unwinding assembly 8 includes a positioning frame 81, a stepper motor 82, and an unwinding roller 83. The positioning frame 81 is fixedly connected to the outside of the cutting table 1. The stepper motor 82 is installed on the outside of the positioning frame 81. One end of the unwinding roller 83 is fixedly connected to the motor shaft of the stepper motor 82 through a coupling.

[0042] A linear shaft 9 is also installed at the connection between the cutting table 1 and the sliding seat 72. The linear shaft 9 passes through both sides of the sliding seat 72 and is fixedly connected to the surface of the cutting table 1.

[0043] The sliding seat 72 has through holes 10 on both sides that are adapted to the size of the linear shaft 9.

[0044] A cloth strip collection box 11 is also provided on the lower outer side of the cutting table 1 near the pusher plate 75.

[0045] A limit switch 12 is also installed on the side of the fixed frame 2 near the support frame 73.

[0046] The usage process of the canvas production slitting device in this embodiment is roughly as follows:

[0047] Before cutting, stepper motor 82 can be started to drive unwind roller 83. After unwind roller 83 winds up the fabric to be cut, one end of the fabric is pulled and passed through the bottom of fixed frame 2, cutting machine body 5 and support frame 73 in sequence. Then, hydraulic cylinder 74 is started to press the fabric end against the lower end of push plate 75. According to the length of the fabric strip to be cut, push cylinder 71 is started. The output end of push cylinder 71 pushes sliding seat 72. Sliding seat 72 moves stably along the outer circle of linear axis 9 along the opening surface of through hole 10, thereby driving the upper support frame 73 and push plate 75 to move stably along the X-axis to control the length of the fabric strip to be cut. At the same time, the hydraulic cylinder 62 above the positioning support 61 can be activated simultaneously. Its piston end pushes the auxiliary tensioning plate 63 and slightly presses it against the other side of the fabric, so that the pushing plate 75 can ensure that the fabric is always in a taut state when dragging the fabric. Then, the linear motor 3 is activated. The motor actuator drives the connecting frame 4 and the cutting machine body 5 to move smoothly and quickly cut the fabric below. The cut fabric is pressed under the pushing plate 75, while the uncut fabric is pressed against the auxiliary tensioning plate 63. Then, the pushing cylinder 71 is activated to move the cut fabric strips out of the cutting table 1 and into the fabric strip collection box 11 for unified collection.

[0048] The beneficial technical effects of the canvas cutting device for fabric production according to the embodiments of this application are roughly as follows:

[0049] The pusher plate 75 of this device always presses against one end of the fabric, and together with the auxiliary tensioning plate 63, keeps the fabric taut. The length of the fabric strip to be cut is determined by controlling the length of the fabric pushed by the pusher plate 75. The cutting machine body 5 moves stably along the moving end of the linear motor 3 and completes the cutting. The cut fabric strip is still pressed against the pusher plate 75 and separated from the uncut fabric. By restarting the pusher cylinder 71, the fabric strip can be pushed into the fabric strip collection box 11 for unified collection. After repeating this operation, flexible cutting and automatic collection of fabric strips can be achieved, thereby effectively ensuring the cleanliness of the cutting table 1 and improving work efficiency.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
