[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Rolling door curtains are the curtain material used for rolling doors. They are typically composed of individual pieces that can be cut and assembled according to the door's size and requirements. They are typically made from materials such as PVC (polyvinyl chloride) and PU (polyurethane) that are heat-resistant, waterproof, and dustproof. These curtains typically offer excellent flexibility and abrasion resistance, making them suitable for raising and lowering and winding rolling doors. They also provide sound insulation, heat insulation, and windproofing, making them suitable for decorative and partitioning doors and windows in a variety of commercial, industrial, and residential settings.

[0024] Example 1:

[0025] Based on the technical defects of existing technologies that cannot achieve good coordination and linkage operations due to insufficient coordination, please refer to Figure 1-Figure 5 The present invention provides a rolling shutter curtain sheet cutting mechanism, which links the feeding process with the cutting process, so that the roll material is more coordinated when cutting, and can achieve good cooperation and linkage operation, and can continuously and quickly produce curtain sheets, thereby improving production efficiency and quality. It includes two groups of side plates 1 and a feeding table 7 fixedly connected between the two groups of side plates 1. Motors 2 are installed on the side walls of the two groups of side plates 1. Half gears 3 are fixed on the output shaft of the motor 2. The half gears 3 are respectively engaged with a feeding unit 4 for pushing the roll material and a cutting unit 5 for equidistantly cutting the roll material. Two symmetrically arranged cutter units 6 are installed between the two groups of cutting units 5; when cutting, the motor 2 drives the half gear 3 to rotate. When the half gear 3 is engaged with the feeding unit 4, the roll material can be pushed forward. When the half gear 3 is engaged with the cutting unit 5, the cutter unit 6 can be driven to move, thereby cutting the roll material.

[0026] To control the movement of the cutter unit 6 and perform cutting work, please refer to Figure 3 The cutting unit 5 includes a transmission assembly 51 that meshes with the half gear 3. The transmission assembly 51 is fixedly connected to the fixed shaft 52, and the fixed shaft 52 is rotatably connected to the side wall of the side plate 1. A turntable 53 is also fixed on the fixed shaft 52. The side wall of the turntable 53 is hinged to the side walls of the two sliders 55 through a connecting rod 54 near the edge. The two sliders 55 are respectively slidably arranged in two sliding holes opened on the side plate 1. The two sliders 55 are respectively fixed at both ends of the cutter unit 6; when the half gear 3 is engaged with the transmission assembly 51, under the action of the transmission assembly 51, the fixed shaft 52 can be driven to rotate under the action of the transmission assembly 51, and the fixed shaft 52 drives the turntable 53 to rotate. The turntable 53 drives the slider 55 to move through the connecting rod 54, so that the two groups of cutter units 6 can move and perform cutting work.

[0027] For easy feeding, please refer to Figure 2 The feeding unit 4 includes a feeding roller 42 rotatably connected between the two side plates 1. One end of the two feeding rollers 42 is fixed with a meshing synchronous gear 41, and the synchronous gear 41 at the bottom is meshed with the half gear 3; when the half gear 3 is meshed with the synchronous gear 41 below, the two synchronous gears 41 are meshed with each other, thereby driving the two feeding rollers 42 to rotate, thereby pushing the coil forward.

[0028] To achieve linkage with feeding, please refer to Figure 3 and Figure 4 The transmission assembly 51 includes a full gear 511 that meshes with the half gear 3. The full gear 511 is rotatably connected to the side wall of the side plate 1. A rocker arm 512 is fixed to the full gear 511. The rocker arm 512 is provided with a bar hole. A fixing pin 513 is provided in the bar hole. The fixing pin 513 is fixed to one end of a tooth plate 514. A transmission gear 517 is provided on the tooth plate 514 and meshed with it. The transmission gear 517 is fixed to the fixed shaft 52. When the half gear 3 is meshed with the full gear 511, the full gear 511 can drive the rocker arm 512 to rotate. The rocker arm 512 drives the tooth plate 514 to move through the fixing pin 513. The tooth plate 514 drives the fixed shaft 52 to rotate through the meshing action with the transmission gear 517, thereby moving the cutter 62 and performing cutting.

[0029] After the cutting is completed, in order to facilitate the reset of the cutter 62, the tooth plate 514 is sleeved in the guide block 515, and the guide block 515 is fixedly connected to the side wall of the side plate 1. A tension spring is fixed between the guide block 515 and the tooth plate 514; when the half gear 3 is no longer engaged with the full gear 511, the tension of the tension spring causes the tooth plate 514 to reset, thereby driving the cutter 62 to reset.

[0030] Example 2:

[0031] When the cutting edge of the cutter 62 is damaged, the cutter 62 needs to be replaced separately. Please refer to Figure 5 On the basis of the first embodiment, the cutter unit 6 includes a knife holder 61 fixed between the two sliders 55, and a cutter 62 is detachably mounted on the bottom of the knife holder 61 by a bolt 63; after unscrewing the bolt 63, the cutter 62 can be removed and then replaced.

[0032] To ensure that the cutter 62 is more firmly installed, a stepped groove is provided at the connection between the blade holder 61 and the cutter 62; the setting of the stepped groove makes the contact area of ​​the connection position between the cutter 62 and the blade holder 61 larger, thereby making the installation more secure.

[0033] It can be seen from the above embodiment that during cutting, the motor 2 is used to drive the half gear 3 to rotate. When the half gear 3 is engaged with the feeding unit 4, the half gear 3 is engaged with the synchronous gear 41 below. Since the two synchronous gears 41 are engaged with each other, the two feeding rollers 42 can be driven to rotate, thereby pushing the coil forward. When the half gear 3 is engaged with the cutting unit 5, the half gear 3 is engaged with the full gear 511. The full gear 511 can drive the rocker arm 512 to rotate. The rocker arm 512 drives the tooth plate 514 to move through the fixed pin 513. The tooth plate 514 drives the fixed shaft 52 to rotate through the meshing action with the transmission gear 517. The fixed shaft 52 drives the turntable 53 to rotate. The turntable 53 drives the slider 55 to move through the connecting rod 54, thereby moving the two sets of cutter units 6 and performing the cutting work.
