[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figures 1 to 6As shown, a processing device for environmentally friendly paper corner protectors includes a positioning mechanism 10, a conveying mechanism 20 and a punching mechanism 30, wherein:

[0032] The positioning mechanism 10, the conveying mechanism 20 and the punching mechanism 30 are arranged from bottom to top;

[0033] The positioning mechanism 10 is used to automatically position a pair of environmentally friendly paper corner protectors 40 below the punching mechanism 30;

[0034] The conveying mechanism 20 is provided in a pair and is symmetrically arranged on the positioning mechanism 10. The conveying mechanism 20 is used to automatically convey an environmentally friendly paper corner protector 40 to the bottom of the punching mechanism 30;

[0035] The punching mechanism 30 is used to automatically punch out a right-angled triangle-shaped process opening on a pair of environmentally friendly paper corner protectors 40 .

[0036] In this embodiment, the positioning mechanism 10 includes a bottom plate 101, a hydraulic cylinder 102 and a positioning plate 107. The bottom plate 101 is horizontally arranged, and the hydraulic cylinder 102 is provided with a pair of symmetrical front and rear connected to the front and rear sides of the bottom plate 101. The hydraulic cylinder 102 is vertically upwardly arranged and connected to a hinge seat 103 at the end of its piston rod, and a pair of "L"-shaped hinge bars 104 are hinged on the hinge seat 103. The bottom plate 101 is symmetrically installed with a pair of hinge seats 2 105 on the left and right sides of the hydraulic cylinder 102, and is hinged on the hinge seat 2 105. There is a "|"-shaped hinge bar 2 106, and the other end of the hinge bar 104 is hinged to the other end of the adjacent hinge bar 2 106. The positioning plates 107 are provided in a pair and are symmetrically arranged on the left and right. The two ends of the positioning plates 107 are correspondingly connected to the inner sides of the front and rear hinge bars 104. A right-angled triangle dropout port 107a is provided in the middle of the positioning plate 107, and a number of circular adsorption holes 107b are evenly provided on the front and rear sides of the dropout port 107a. An air suction pipe 108 is connected to the bottom of the adsorption hole 107b, and the air suction pipe 108 is connected to an external negative pressure air source. The piston rod of the hydraulic cylinder 102 contracts and drives the positioning plates 107 on both sides to flip inward 45 degrees, so that the positioning plates 107 on both sides are aligned with the output ends of the conveying lines of the two environmentally friendly paper corner protectors 40. When the environmentally friendly paper corner protectors 40 are conveyed to the preset position on the upper side of the positioning plates 107, a negative pressure suction force is generated at the adsorption hole 107b by the negative pressure air source, thereby firmly adsorbing the environmentally friendly paper corner protectors 40 on the upper side of the positioning plates 107. Then, the piston rod of the hydraulic cylinder 102 extends and drives the positioning plates 107 on both sides to flip outward 45 degrees, so that the positioning plates 107 on both sides are aligned directly below the pair of punching knives 308.

[0037] In this embodiment, the conveying mechanism 20 includes a fixed plate 201, a motor 202 and a conveying shaft 203. The two ends of the fixed plate 201 are correspondingly connected to the outer sides of the front and rear hinge strips 104. The motor 202 is installed outward in the middle of the fixed plate 201, and a conveying wheel 204 is installed on the output shaft of the motor 202. The conveying shaft 203 is provided with two rows and is correspondingly arranged on the front and rear sides of the motor 202. The lower end of each conveying shaft 203 is rotatably connected to the fixed plate 201, and the upper end of each conveying shaft 203 is also installed with a conveying wheel 204. All the conveying wheels 204 are connected by a conveyor belt 205. The inner and outer end surfaces of the conveying wheels 204 are installed with circular limit plates 206. When the positioning plates 107 on both sides are aligned with the output ends of the two conveying lines of the environmentally friendly paper corner protectors 40, the motor 202 drives a row of conveying wheels 204 to rotate, and then the conveyed environmentally friendly paper corner protectors 40 continue to be conveyed to the preset position on the upper side of the positioning plates 107. During the conveying process, the environmentally friendly paper corner protectors 40 are limited by a pair of limiting plates 206 on the conveying wheels 204.

[0038] In this embodiment, the punching mechanism 30 includes a top mounting plate 301, a mounting column 302, a hydraulic cylinder 2 303 and a lifting plate 304. The top mounting plate 301 is arranged parallel to and directly above the bottom mounting plate 101. Several mounting columns 302 are provided and are evenly connected between the top mounting plate 301 and the bottom mounting plate 101. The hydraulic cylinder 2 303 is arranged vertically downward and connected to the center of the top mounting plate 301. The lifting plate 304 is horizontally connected to the end of the piston rod of the hydraulic cylinder 2 303. A pair of knife base plates 307 are symmetrically connected to the lower side of the lifting plate 304. The lower side of the knife base plate 307 is connected to an "L"-shaped punching knife 308. When the positioning plates 107 on both sides are aligned directly below the pair of punching knives 308, the piston rod of the hydraulic cylinder 2 303 extends and drives the pair of punching knives 308 to penetrate the environmentally friendly paper corner protector 40 and insert into the blanking port 107a, thereby punching out a right-angled triangle process groove on the environmentally friendly paper corner protector 40.

[0039] In this embodiment, a teardrop-shaped positioning block 109 is hingedly connected to the rear side of the positioning plate 107. The positioning block 109 can be installed to block the incoming environmentally friendly paper corner protectors 40 and remove the blockage of the punched environmentally friendly paper corner protectors 40.

[0040] In this embodiment, vertical guide posts 305 are connected to both ends of the lifting plate 304. The guide posts 305 slidably engage with the top mounting plate 301 via guide sleeves 306. The addition of guide posts 305 and guide sleeves 306 can limit the deflection freedom of the piston rod of the second hydraulic cylinder 303 and increase the accuracy of the punching blade 308 in smoothly inserting into the blanking opening 107a.

[0041] The practical application of this processing equipment for environmentally friendly paper corner protectors includes the following work contents:

[0042] Step 1: The piston rod of the hydraulic cylinder 102 is contracted and driven to flip the positioning plates 107 on both sides inward by 45 degrees, so that the positioning plates 107 on both sides are aligned with the output ends of the conveying lines of the two environmentally friendly paper corner protectors 40. When the environmentally friendly paper corner protectors 40 are conveyed to the upper side of the positioning plates 107, the vertical positioning blocks 109 are used to block the conveyed environmentally friendly paper corner protectors 40, and then a negative pressure air source is used to form a negative pressure suction force at the adsorption hole 107b, thereby firmly adsorbing the environmentally friendly paper corner protectors 40 on the upper side of the positioning plates 107. Then, the piston rod of the hydraulic cylinder 102 is extended and driven to flip the positioning plates 107 on both sides outward by 45 degrees, so that the positioning plates 107 on both sides are aligned directly below the pair of punching knives 308.

[0043] Step 2: When the positioning plates 107 on both sides are aligned with the output ends of the two conveyor lines of the environmentally friendly paper corner protectors 40, the motor 202 drives a row of conveying wheels 204 to rotate, and then the conveyed environmentally friendly paper corner protectors 40 continue to be conveyed to the preset position on the upper side of the positioning plates 107. During the conveying process, the environmentally friendly paper corner protectors 40 are limited by a pair of limiting plates 206 on the conveying wheels 204.

[0044] Step 3: When the positioning plates 107 on both sides are aligned directly below the pair of punching knives 308, the piston rod of the hydraulic cylinder 2 303 extends and drives the pair of punching knives 308 to penetrate the environmentally friendly paper corner protector 40 and insert into the blanking port 107a, thereby punching out a right-angled triangle process groove on the environmentally friendly paper corner protector 40.

[0045] Step 4: Use the vertical positioning block 109 to remove the obstruction of the environmentally friendly paper corner protector 40 being transported, and then use the motor 202 to drive a row of conveying wheels 204 to rotate, and then continue to transport the punched environmentally friendly paper corner protector 40 away.

[0046] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
