Description

Technical Field

[0001] The utility model belongs to the technical field of cutting machines, in particular to an automatic cutting machine for producing electric blankets. Background Art

[0002] An electric blanket, also known as an electric mattress, is a contact heating device composed of heating wire and various fabrics. Suitable for winter homes without heating, they are primarily used to increase the temperature inside the bed while sleeping. During production, the fabric must be cut to a predetermined size and shape. Improper cutting can negatively impact subsequent production and product quality. Patent publication number "CN214655946U" discloses a rapid cutting device for electric blankets, comprising a cloth frame and a tabletop. The cloth frame comprises two bases and a first branch pipe mounted on the bases, the bases being provided with a first support slot for receiving the first branch pipe. The tabletop comprises a support assembly and a cutting assembly. The support assembly comprises two fixed bases and a second branch pipe mounted on the bases. The fixed bases are provided with a fixing block and a support. The support is provided with a second support slot for receiving the second branch pipe. The fixing block is provided with a fixing slot for engaging the tabletop and a knob for pressing the tabletop. The cutting assembly comprises a cutting frame, a push rod, and a positioning seat fixed to the tabletop. The push rod is positioned between the tabletop and the cutting frame. The cutting frame comprises a slide bar and a cutting machine, the cutting machine being slidably connected to the cutting frame. The positioning seat is provided with multiple rotatable pulleys closely attached to both sides of the slide bar. This utility model has a simple structure, is easy for workers to operate, has a fast cutting speed, and is inexpensive to manufacture. However, during cutting, the fabric shakes during the rotation and unfolding process, causing the fabric to stretch and tilt. Without correcting the fabric, the fabric may easily deviate from the cutting size due to the deflection. Utility Model Content

[0015] Preferably, a rack is provided on the opposite sides of the two first mounting seats, and a rotating block is provided on the lifting frame which is rotated by a torsion spring, and a clamping block is fixedly provided at one end of the rotating block, and the clamping block is engaged and connected with the rack; pinch one end of the rotating block and rotate it to disengage the clamping block from the rack, and after moving the lifting frame up and down to a suitable position, release the rotating block, and drive the rotating block to rotate under the action of the torsion spring so that the clamping block is engaged with the rack, thereby completing the fixation of the lifting frame.

[0046] The blanket is laid flat on the cutting table 1, and the two first mounting seats 53 are moved relative to or away from each other by rotating the second threaded rod 52. The distance between the two first mounting seats 53 is adjusted so that the two sides of the blanket are in contact with the side surfaces of the first slider 55. The lifting frame 57 is moved on the first mounting seat 53 to adjust the height of the limit plate 58 so that the limit plate 58 is in contact with the top of the blanket to prevent the blanket from curling. After the adjustment is completed, the moving component 4 drives the flattening component 3 and the correcting component 5 to move along the direction of the blanket rolling. The correcting component 5 is arranged on the side of the flattening component 3 close to the cutting component 2. The correcting component 5 first corrects the blanket and then flattens it through the flattening component 3. Both sides of the blanket are in contact with the first slider 55. If the blanket is offset, the offset side will produce an extrusion force on the first slider 55, causing the first slider 55 to slide into the first groove 53, compressing the first spring 56. The first spring 56 produces a reaction extrusion force on the first slider 55 due to the elastic recovery effect, pushing the first slider 55 out of the first groove 53.

The correction assembly 5 first corrects the blanket, and then The flattening assembly 3 flattens the blanket, and both sides of the blanket contact the first slider 55. If the blanket deviates, the deviated side exerts an extruding force on the first slider 55, causing the first slider 55 to slide into the first groove 53, compressing the first spring 56. The first spring 56 exerts a counter-extruding force on the first slider 55 due to its elastic recovery effect, pushing the first slider 55 out of the first groove 53. The first slider 55 exerts a thrust on the blanket, correcting the deviated side to the correct position. After the correction is completed, the flattening roller 32 flattens the surface of the blanket to prevent wrinkles. After the correction and flattening are completed, the connecting strip 514 is engaged in the second groove 12 due to the elastic force of the second spring 35. At this time, the limit plate 58 fixes the end of the blanket due to the action of the second spring 35. The cutting assembly 2 is started to cut the blanket to improve cutting accuracy. After cutting is completed, the cylinder 45 is started to drive the flattening assembly 3 to move upward and then the motor 42 is rotated in the opposite direction to return the flattening assembly 3 and the correction assembly 5 to their original positions.

[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
