Description

Technical Field

[0001] The utility model relates to the field of bending devices, in particular to a food packaging box bending device. Background Art

[0002] Food packaging is an outer packaging used to protect food. After the food leaves the factory, food packaging can protect the food from contamination. Food packaging is generally divided into inner packaging and outer packaging. The inner packaging is generally made of plastic, while the outer packaging is generally made of cardboard. In order to shape the cardboard, it is usually necessary to use a bending device to bend it into a suitable shape. When bending, it is generally necessary to use a pressing plate to fix the cardboard first. Since the cardboard itself has a weak ability to withstand longitudinal extrusion, the pressing plate squeezing the cardboard may cause damage to the cardboard.

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.

[0031] Reference Figure 1 - Figure 3 The folding plate 2 is hinged on the left end of the machine 1 for driving the cardboard to bend, and the front end of the bending plate 2 is installed with a bending motor 5 for driving the bending plate 2 to rotate. The top of the machine 1 is provided with a fixing component 3 for fixing the cardboard, and the fixing component 3 includes a slide plate 32 for driving the top plate 33 to move, and the slide plate 32 passes through and is slidably connected to the top of the machine 1. The top of the slide plate 32 is fixedly connected to the top of the top plate 33 for driving the extrusion spring 36 to move, and the top of the top plate 33 is provided with an adjusting component 4 for adjusting the initial spacing between the top plate 33 and the extrusion plate 34. The adjusting component 4 includes a sliding sleeve 45 for supporting the knob 41, and the sliding sleeve 45 passes through and is slidably connected to the top of the top plate 33. The sliding sleeve 45 can slide up and down at the top of the top plate 33 but cannot rotate. The top of the sliding sleeve 45 is rotatably connected to the knob 41 for pulling the threaded rod 44.

[0032] Reference Figure 2 - Figure 4 The fixing assembly 3 also includes a squeezing plate 34 for squeezing the cardboard. The squeezing plate 34 is slidably connected to the outer wall of the slide plate 32. The slide plate 32 can support the squeezing plate 34 so that it can slide vertically up and down. The top of the squeezing plate 34 is fixedly connected to a slide rod 35 for supporting the squeezing spring 36. The slide rod 35 passes through and is slidably connected to the top of the top plate 33. The top of the squeezing plate 34 is fixedly connected to an squeezing spring 36 for pushing the squeezing plate 34. The top of the squeezing spring 36 is fixedly connected to the bottom end of the top plate 33. The top plate 33 can push the squeezing spring 36 To extrude the extrusion plate 34. During processing, when the distance between the extrusion plate 34 and the top plate 33 changes, it means that the extrusion force is sufficient and the extrusion can be stopped. The adjustment component 4 also includes a threaded rod 44 for driving the extrusion plate 34 to move up and down. The threaded rod 44 is fixedly connected to the top of the extrusion plate 34. The knob 41 is threadedly connected to the threaded rod 44. The threaded rod 44 can be driven to move upward by rotating the knob 41 clockwise. The top of the threaded rod 44 is fixedly connected to a closing cover 42 for preventing the knob 41 from separating from the threaded rod 44.

[0033] Reference Figure 2 - Figure 4The inner wall of the sliding sleeve 45 is slidably connected with a sliding ring 47 for driving the fixed block 49 to move. The top of the sliding ring 47 is fixedly connected with a fixed block 49 for fixing the knob 41. The front end of the fixed block 49 is provided with an inclined surface. When the inclined surface is squeezed, the fixed block 49 will be forced to move downward. The bottom end of the knob 41 is provided with a fixing groove 410 for accommodating the fixing block 49. The fixing block 49 and the fixing groove 410 are adapted. When the fixing block 49 is inserted into the fixing groove 410, the knob 41 will be restricted from rotating counterclockwise. The bottom end of the sliding ring 47 is fixedly connected with a fixing spring 46 for pushing the sliding ring 47. The bottom end of the fixing spring 46 is fixedly connected to the inner wall of the sliding sleeve 45, and the fixing spring 46 will always push the sliding ring 47 upward. The left end of the sliding ring 47 is fixedly connected with an unlocking block 43 for driving the sliding ring 47 to move. The unlocking block 43 is set to be L-shaped. By pressing the unlocking block 43, the sliding ring 47 can be driven to move downward. The outer wall of the knob 41 is fixedly connected with an anti-sliding block 48 for facilitating the operator to rotate the knob 41. The anti-sliding block 48 is set to be rectangular. The rectangular anti-sliding block 48 can provide more lateral friction, which can facilitate the operator to rotate the knob 41. The inner wall of the machine 1 is installed with an electric telescopic rod 31 for driving the slide 32 to move. The output shaft of the electric telescopic rod 31 is installed at the bottom end of the slide 32. The electric telescopic rod 31 is a prior art. Due to the prior art, this case will not be described in detail. The top of the machine 1 is provided with a placement slot 6 for placing cardboard.

[0034] Working principle: Place the cardboard to be bent in the placement slot 6 at the top of the machine 1, start the electric telescopic rod 31, push the slide 32 to move, thereby driving the top plate 33 and the squeezing plate 34 to move toward the cardboard. After the squeezing plate 34 contacts the cardboard, it will be subjected to the reaction force of the cardboard, causing the squeezing plate 34 to move upward, causing the squeezing spring 36 to be compressed. When the distance between the squeezing plate 34 and the top plate 33 changes, the appropriate squeezing force is reached, and the movement of the electric telescopic rod 31 can be stopped at this time.

[0035] According to the carrying capacity of different cardboards, the extrusion force can be adjusted by adjusting the initial length of the extrusion spring 36. The specific operation is to rotate the knob 41. Since the knob 41 is threadedly connected to the threaded rod 44, when the knob 41 is rotated clockwise, the threaded rod 44 moves upward, driving the extrusion plate 34 to move upward, thereby changing the initial length of the extrusion spring 36. In the process of rotating the knob 41, when the inclined surface at the front end of the fixed block 49 is squeezed, the fixed block 49 will be forced to move downward, compressing the fixed spring 46. When the extrusion plate 34 moves to a suitable height, the knob 41 can be released, and the fixed spring 46 pushes the sliding ring 47 to move upward, so that the fixed block 49 is inserted into the fixing groove 410, limiting the knob 41 from rotating counterclockwise to ensure the stability of the device.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
