Description

Technical Field

[0001] The utility model relates to the technical field of folding machines, in particular to a plastic plate folding machine. Background Art

[0002] Plastic sheets (such as PP hollow sheets, polyethylene sheets, polypropylene sheets, etc.) are widely used to make various packaging boxes, packaging boxes, pet houses and other products. Plastic sheets are in plate shape after production, so they need to be folded before they can be assembled. The folding machine on the market usually folds the plastic sheet by fixing the plastic sheet first and then bending it by heating.

[0003] For example, Chinese patent application number: CN201410744184.2 discloses an automatic bending machine for plastic plates, which is characterized in that it includes a workbench, the upper side edge of the workbench is hinged with an upper pressing plate, and the lower side edge is hinged with a lower pressing plate, and the upper pressing plate and the lower pressing plate are driven by an upper pressing motor and a lower pressing motor respectively to rotate along the upper and lower sides of the workbench; the left and right sides of the workbench are hinged with a left bending plate and a right bending plate respectively, and the left bending plate and the right bending plate are driven by a left bending motor and a right bending motor respectively to rotate along the left and right sides of the workbench, and the inner sides of the hinged edges of the left bending plate and the right bending plate are provided with heating tubes, and the upper pressing plate, the lower pressing plate, the left bending plate and the right bending plate are all rotated toward the center of the workbench. This type of automatic bending machine for plastic plates has at least the following problems: 1. During operation, the upper pressing plate and the lower pressing plate rotate relative to each other to press the plastic plate. During the process of the upper and lower pressing plates pressing the plastic plate, since the plastic plate may not be centered, the plastic plate may be skewed when it is fixed, affecting the folding quality. 2. After the upper and lower pressing plates press the plastic plate, only the left bending plate and the right bending plate bend the plastic plate, and only two edges can be bent at a time, resulting in low work efficiency.

The safety grating 11 is arranged on both sides of the front of the frame 10 to improve the safety of the folding machine. The first folding part 13, the second folding part 31, and the third folding part 41 have one or more. In this embodiment, the first folding part 13, the second folding part 31, and the third folding part 41 each have four, which are surrounded by a rectangular shape, and a single or multiple folding actions can be performed at one time. The ejection part 17 is rod-shaped, and the ejection part 17 is driven by the fourth cylinder to move up and down in the feeding trough 14. The size of the feeding trough 14 is matched with the plastic sheet 15. The preferred folding steps: 1. The manual / manipulator puts the plastic sheet 15 into the feeding trough 14, and the first folding part 13 accurately positions the plastic sheet 15. 2. The pressing plate 21 presses the plastic sheet 15 in the feeding trough 14 so that the plastic sheet 15 does not move. 3. The heated third folding part 41 presses on the first folding part 13, and then the second folding part 31 pushes the folding of the plastic sheet 15, so that the plastic sheet 15 completes the folding action. 4. The second folding component 31 and the third folding component 41 are reset; the ejection component 17 lifts up the folded plastic sheet 15 to facilitate manual / mechanical removal of the folded finished product.

When the plastic sheet 15 is placed in the material placement groove 14 for positioning, the vacuum pump causes the suction holes 16 to suck the bottom surface of the plastic sheet 15 through the pipeline, which further ensures the accuracy of the positioning of the plastic sheet 15 and prevents any displacement.

[0040] Preferably, the support plate 12 is also provided with a plurality of CCD detection cameras, which can take photos of the folded plastic sheet 15 for detection. In this embodiment, there are four CCD detection cameras, and each folded edge corresponds to a CCD detection camera. The CCD detection camera can be used to detect the bending quality of the plastic sheet 15 to confirm whether the product is qualified.

[0041] In summary, the design focus of the utility model is that when bending, the plastic sheet 15 is placed in the material placement groove 14 formed by the first folding component 13, and then the pressing plate 21 presses the plastic sheet 15 in the material placement groove 14 to ensure that the plastic sheet 15 is accurately positioned when bending without displacement. With one or more groups of first folding components 13, second folding components 31, and second folding components 31 working together, one or more plastic sheets 15 can be folded at a time, and the work efficiency is higher.
