[0028] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figures 1 to 5As shown, an embodiment of the present application discloses an automatic cutting device for automobile ceiling fabric, comprising a storage rack 1, a cutting rack 2 and a pulling rack 3 fixed to the ground in sequence, wherein the storage rack 1 is used to place a fabric roll 4, specifically, a horizontally arranged fixed shaft is provided on the storage rack 1, the fabric roll 4 is mounted on the fixed shaft, and the fixed shaft can rotate around its own axis to facilitate the movement of the free end of the fabric roll 4; that is, when the free end of the fabric roll 4 receives a certain amount of pulling force, the entire fabric roll 4 rotates together with the fixed shaft to realize the unfolding movement of the free end of the fabric roll 4.

[0030] In addition, a fabric leveling assembly is provided on the side of the cutting frame 2 close to the storage frame 1, and a cutting knife assembly capable of moving back and forth along the width direction of the fabric is provided on the other side of the cutting frame 2. A clamping assembly and a driving assembly for moving the clamping assembly toward a side away from the storage frame 1 are provided on the pulling frame 3; when the free end of the fabric roll 4 passes through the fabric leveling assembly and reaches the clamping station, the clamping assembly is used to clamp the free end of the fabric roll 4, and the driving assembly is used to drive the clamping assembly to pull the free end of the fabric roll 4 toward a set position away from the storage frame 1, and the cutting knife assembly is used to automatically cut the free end of the fabric roll 4 according to the set length. The whole process only requires manual placement of the fabric roll 4 on the fixed shaft at the beginning, and then pulling the free end of the fabric roll 4 to pass through the fabric leveling assembly all the way to the clamping station, and all subsequent operations do not require manual participation, thereby realizing rapid and automatic cutting of the fabric.

[0031] In the present embodiment, further, a material guide bracket 5 for supporting and guiding the fabric is provided on the side of the material storage rack 1 close to the cutting rack 2, and the upper end surface of the material guide bracket 5 is flush with the feed channel of the fabric leveling component, thereby better ensuring that the free end of the fabric roll 4 can enter the feed port of the fabric leveling component in the horizontal direction, thereby improving the fabric leveling effect.

[0032] More specifically, the fabric leveling assembly in this structure includes two rollers 6 which are symmetrically arranged up and down, and the two ends of the two rollers 6 are rotatably connected to the cutting frame 2 respectively. A pressing channel is left between the two rollers 6, and the pressing channel is also. The gap of the pressing channel in the above structure is adjustable, which means that the cutting gap is adjustable to better suit the leveling of fabrics of different thicknesses, and has strong versatility.

[0033] The two ends of the cutting frame 2 are respectively provided with vertically arranged first driving cylinders 7, and the driving ends of the two first driving cylinders 7 are respectively connected to the two ends of the roller shaft 6 located above, so that the roller shaft 6 above can move vertically to achieve the gap adjustment of the pressing channel.

[0034] See the attached Figure 3In this embodiment, the driving assembly includes a horizontally arranged mounting frame 8 and a horizontally arranged second driving cylinder 9. The mounting frame 8 is slidably connected to the material pulling frame 3 along the conveying direction of the fabric, and the driving end of the second driving cylinder 9 is connected to the mounting frame 8; the clamping assembly is connected to one end of the mounting frame 8 close to the cutting frame 2. In this structure, the mounting frame 8 includes a transverse profile arranged along the width direction of the fabric and a plurality of longitudinal profiles arranged perpendicular to the transverse profile, and one end of the plurality of longitudinal profiles is respectively fixedly connected to the transverse profile, and the other ends of the plurality of longitudinal profiles are respectively slidably connected to the material pulling frame 3; more specifically, a gate-type bracket is arranged at the upper end of the material pulling frame 3, the crossbeam of the gate-type bracket is parallel to the transverse profile, and a plurality of guide sliders are arranged on the lower end surface thereof, and guide rails respectively slidably matched with the plurality of guide sliders are arranged on the upper end surface of each longitudinal profile.

[0035] In addition, the material clamping assembly includes a plurality of clamping jaws 10 arranged at intervals along the width direction of the fabric and a plurality of clamping jaw cylinders 11 for respectively driving the clamping jaws 10 to open and close. The plurality of clamping jaw cylinders 11 drive the clamping jaws 10 to close and open, so as to achieve clamping and limiting of the free end of the fabric roll 4, and under the action of the driving assembly, the free end of the fabric roll 4 is driven to move in the unfolding direction (away from the storage rack 1) to a set position, where the set position sets the set length position of the fabric to be cut, that is, when the free end of the fabric roll 4 is clamped and moved to this position, the cutting knife assembly starts to cut the fabric transversely.

[0036] See attached Figure 5 In this embodiment, the cutter assembly includes a disc-shaped blade 12 and a motor 13 for driving the blade 12 to rotate, that is, the center position of the blade 12 is connected to the output shaft of the motor 13; in addition, a rodless cylinder 14 extending along the width direction of the fabric is provided on the cutting frame 2, and the motor 13 is connected to the slider of the rodless cylinder 14. The movement of the slider causes the motor 13 and the blade 12 to move along the width direction of the fabric. As the blade 12 rotates, the fabric can be cut horizontally.

Through the operation of the two third driving cylinders 17, the first movable pressing plate 16 is driven to fully press and limit on the upper surface of the fabric, thereby realizing the pressing and limiting on one side of the fabric cutting position.

[0039] In addition, the second material pressing assembly includes a second movable pressing plate 18 and a third movable pressing plate 19 which are spaced apart from each other and are parallel to each other. The two ends of the second movable pressing plate 18 and the third movable pressing plate 19 are respectively connected to the cutting frame 2 in a vertically slidable manner. The upper and lower parts of the two ends of the cutting frame 2 are provided with a fourth driving cylinder 20 and a fifth driving cylinder 21 for respectively driving the second movable pressing plate 18 and the third movable pressing plate 19 to rise and fall. Similarly, in this structure, the second movable pressing plate 18 and the third movable pressing plate 19 are driven to approach each other by the fourth driving cylinder 20 and the fifth driving cylinder at the upper and lower parts, so as to realize the clamping and limiting on the other side of the fabric cutting position, so that the fabric position will not move when the blade 12 is cutting, and the cutting surface is ensured to be continuous and straight. Here, the second movable pressing plate 18 and the third movable pressing plate 19 are both arranged to be liftable mainly to facilitate the passage of the clamping assembly.

[0040] In this embodiment, the first fixed plate 15, the first movable pressing plate 16, the second movable pressing plate 18 and the third movable pressing plate 19 in the above structure are all connected to the material frame through corresponding aluminum profiles.
