Description

Technical Field

[0001] This utility model belongs to the technical field of bending devices, specifically relating to a plastic box bending and forming device. Background Technology

[0002] Plastic boxes are generally injection molded from high-impact-strength HDPE (high-density polyethylene) and PP (polypropylene). The box body is mostly made by one-time injection molding. Some plastic boxes made of materials such as acrylic sheets are also formed by bending. Plastic boxes are equipped with lids and have functions such as storage and transportation.

[0003] The bending forming device determines the bending curvature of the plastic sheet through a bending mold. When it is necessary to change the bending curvature of the plastic box, the bending mold needs to be replaced as needed. In commonly used bending forming devices, the mold is usually fixedly installed on the hydraulic column. When changing the mold, it is inconvenient to replace the mold, which affects the adjustment efficiency of the device. Utility Model Content

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figure 1 As shown, a plastic box bending and forming device includes a U-shaped support 1 and a bending template 2. The bending template 2 is set on the top of the U-shaped support 1. A bending roller 3 that cooperates with the bending template 2 is set on the top of the U-shaped support 1. A lifting component 4 for driving the bending template 2 to rise and fall is set on the top of one side of the U-shaped support 1. A driving component 5 for driving the bending roller 3 to rotate is set at one end of both sides of the U-shaped support 1. A support plate 6 is fixedly connected to the top of the U-shaped support 1. The support plate 6 is set below the bending template 2.

[0022] According to the above structure, during use, the two drive components 5 drive the bending roller 3 to rotate, thereby causing the bending roller 3 to rotate around the end of the bending template 2, which in turn causes the plastic sheet to rotate around the end of the bending template 2, thus achieving the function of bending the plastic sheet.

[0023] like Figure 3 As shown, a heating roller 21 is embedded at one end of the bending template 2.

[0024] According to the above structure, when bending, the heating roller 21 heats the plastic sheet, thereby facilitating the bending of the plastic sheet.

[0025] like Figure 3 and 4 As shown, the lifting assembly 4 includes a mounting groove 41 located at the top of one side of the U-shaped bracket 1. A support plate 42 is fixedly connected to the bottom end of the mounting groove 41. A sliding plate 43 is slidably connected inside the mounting groove 41. Hydraulic columns 44 are symmetrically arranged at the top end of the support plate 42. The top end of the hydraulic columns 44 is fixedly connected to the bottom end of the sliding plate 43. A square column 45 is symmetrically fixedly connected to one end of the sliding plate 43. The square column 45 is inserted into the inside of the bending template 2. A limit plate 46 is fixedly connected to the side wall of the square column 45. A stud 47 is fixedly connected to one end of the square column 45. The stud 47 penetrates the bending template 2. A nut 48 is threadedly connected to the side wall of the stud 47.

[0026] According to the above structure, during use, the hydraulic column 44 is contracted to pull the slide plate 43 downward, which in turn drives the bending template 2 downward, pressing the plastic plate between the support plate 6 and the bending template 2. When it is necessary to change the bending arc, the nut 48 is removed from the stud 47, and then the bending template 2 is pulled out and replaced with a bending template 2 with a heating roller 21 of the corresponding size. Then, the nut 48 is tightened on the stud 47, and the bending template 2 is then fixedly installed on the square column 45.

[0027] like Figure 2-5 As shown, the drive assembly 5 includes a protruding plate 51 fixedly connected to one end of the U-shaped bracket 1. A mounting plate 52 is rotatably connected to one end of the protruding plate 51. A groove 53 is provided in the middle of the mounting plate 52. A mounting seat 54 is slidably connected inside the groove 53. One end of the bending roller 3 is rotatably connected to the mounting seat 54. Side grooves 55 are provided on both sides of the groove 53. Connecting ears 56 are fixedly connected to both ends of the mounting seat 54. The two connecting ears 56 are slidably connected inside the two side grooves 55 respectively. A forward and reverse motor 510 is fixedly connected to the other end of the protruding plate 51. The output shaft of the forward and reverse motor 510 is fixedly connected to one end of the mounting plate 52. A protrusion 57 is symmetrically fixedly connected to one end of the mounting plate 52. A lead screw 58 is rotatably connected to the middle of the connecting ear 56. The lead screw 58 is threadedly connected to the protrusion 57. A handle 59 is fixedly connected to one end of the lead screw 58.

[0028] According to the above structure, during use, the forward and reverse motors 510 drive the mounting plates 52 to rotate. The two mounting plates 52 drive the bending rollers 3 to rotate around the axis of the heating rollers 21, thereby bending the plastic sheet. When the size of the heating rollers 21 changes, the screw 58 is turned by the handle 59, thereby driving the mounting base 54 to move up and down, so that the bending rollers 3 move away from or closer to the axis of the heating rollers 21, thereby changing the curvature of the bent plastic sheet.

[0029] The working principle of this utility model is as follows: During use, two drive components 5 drive the bending roller 3 to rotate, causing the bending roller 3 to rotate around the end of the bending template 2, thereby causing the plastic sheet to rotate around the end of the bending template 2, thus bending the plastic sheet. During use, the hydraulic column 44 retracts, pulling the sliding plate 43 downwards, which in turn moves the bending template 2 downwards, pressing the plastic sheet between the support plate 6 and the bending template 2. The forward and reverse motors 510 drive the mounting plates 52 to rotate, and the two mounting plates 52 drive the bending roller 3 to rotate around the axis of the heating roller 21, thereby bending the plastic sheet. The plastic sheet is bent. During bending, the heating roller 21 heats the plastic sheet, making it easier to bend. When it is necessary to change the bending curvature, the nut 48 is removed from the stud 47, and then the bending template 2 is pulled out and replaced with a bending template 2 with a heating roller 21 of the corresponding size. Then, the nut 48 is tightened on the stud 47, and the bending template 2 is then fixedly installed on the square column 45. When the size of the heating roller 21 is changed, the screw 58 is turned by the handle 59, which drives the mounting base 54 to move up and down, so that the bending roller 3 moves away from or closer to the axis of the heating roller 21, thereby changing the curvature of the bent plastic sheet.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
