[0034] Working principle:

[0035] The first step: when the equipment is working, the card box 3 that needs to be formed is placed on the rectangular receiving plate 36, and a first limiter 34 is provided on the first assembly plate 31. The edge of the first limiter 34 can limit the card box 3 to ensure the fixed stability of the card box 3. After the edge of the card box 3 is engaged in the first limiter 34, the first oil cylinder 33 is started to allow the telescopic shaft of the first oil cylinder 33 to drive the movement of the forming plate 35. By pushing the forming plate 35 to move, the edge of the forming plate 35 is pushed to contact the edge of the card box 3, and the inflection point on the card box 3 will be pushed to fold. Then, the card box 3 is picked up and the card box 3 is re-engaged in the first limiter 34. Then, the first oil cylinder 33 is started to allow the telescopic rod of the first oil cylinder 33 to push the forming plate 35 to move, so as to push the other side of the card box 3. This device pushes the corner position of the card box 3 by controlling the movement of the telescopic rod in the first oil cylinder 33, pre-processes the card box 3, and facilitates subsequent processing of the card box 3.

[0036] Step 2: Place the card box 3 that needs to be processed later on the top of the forming frame 71, and start the second oil cylinder 45 to move the telescopic rod of the second oil cylinder 45 downward and contact the round rod on the upper and lower telescopic parts 46. The telescopic rod of the second oil cylinder 45 pushes the round rod on the upper and lower telescopic parts 46 to move downward, and the reset elastic part 47 is provided with a structure for fixing the round rod on the upper and lower telescopic parts 46. It has a rebound structure and can be reset when the upper and lower telescopic parts 46 move downward. The downward movement of the upper and lower telescopic parts 46 will drive the downward movement of the first round rod 48, and the downward movement of the first round rod 48 will push the downward movement of the extrusion rectangular plate 52 The downward movement of the extruded rectangular plate 52 will drive the downward movement of the small extruded plate 53. The small extruded plate 53 will first contact the card box 3. Then, as the extruded rectangular plate 52 moves, when the lower surface of the extruded rectangular plate 52 contacts the card box 3, the extruded rectangular plate 52 will push the card box 3 to be engaged in the forming frame 71. The bottom surface of the card box 3 will be engaged in the forming frame 71, and the side wall of the card box 3 will be attached to the inner wall of the forming frame 71. This device controls the up and down movement of the extruded rectangular plate 52 to allow the card box 3 to be engaged in the forming frame 71, and the bottom of the card box 3 to be engaged in the forming frame 71, thereby ensuring the engaging effect of the card box 3 and improving the forming effect of the card box 3.

[0037] Step 3: When the card box 3 is engaged in the forming frame 71, the edge of the card box 3 will contact the second limiting member 67. Under the limitation of the second limiting member 67, the part of the card box 3 that is not engaged in the forming frame 71 will roll up. At the same time, the engaged part of the card box 3 will further curl under the limiting action of the edge of the second limiting member 67 to form a U-shaped structure, which is convenient for the subsequent deformation and assembly of the card box 3. This device sets a second limiting member 67 on the side wall of the rectangular frame 66, so that the second limiting member 67 limits the edge of the card box 3, ensuring that the card box 3 is deformed into a shape suitable for assembly, thereby improving the forming speed of the equipment.

[0038] Step 4: When the box is deformed, the third oil cylinder 62 is started to push the side of the card box 3 to deform, and the fourth oil cylinder 64 is started at the same time to allow the rectangular propulsion plate 65 to push the side of the card box 3 to deform. The position pushed by the rectangular propulsion plate 65 is below the pushing position of the fourth oil cylinder 64. After the card box 3 is formed, the fifth oil cylinder 68 is started to allow the telescopic rod of the fifth oil cylinder 68 to push the rectangular ejection plate 69 upward, thereby pushing the card box 3 upward and detaching from the forming frame 71, thereby completing the entire forming process of the card box 3. This device realizes the pushing of the card box 3 by controlling the work of the third oil cylinder 62, the L-shaped propulsion plate 63 and the fifth oil cylinder 68, thereby ensuring the deformation stability of the card box 3.

[0039] Step 5: After the card box 3 is formed, it will be pushed to the top of the transport slide 14, and then to the top of the conveyor belt 19 from the transport slide 14. By starting the motor 16, the output shaft of the motor 16 drives the rotation of the transmission belt 17, thereby driving the rotation of the driven wheel 18, and the driven wheel 18 starts the conveyor belt 19 to rotate. Through the rotation of the conveyor belt 19, the card box 3 moves on the conveyor belt 19. When the card box 3 reaches the upper surface of the discharge plate 24, under the inclination of the discharge plate 24, the card box 3 slides on the discharge plate 24, and the protective side plate 25 limits the discharge plate 24 to ensure the movement stability of the card box 3. This device realizes the movement of the card box 3 on the conveyor belt 19 by controlling the rotation of the conveyor belt 19, thereby ensuring the movement stability of the card box 3 and facilitating the transportation of the card box 3.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
