Description

Technical Field

[0001] The present invention belongs to the technical field of folder production, and particularly relates to a full-automatic edge protector. Background Art

[0002] Existing larger folders are usually composed of two panels connected. During use, due to collisions, squeezes, etc., the folder panels are extremely prone to breakage or wear at the side and corner positions, which not only affects the appearance, but also will cause the folder panels to be damaged more severely over time, affecting the service life.

[0003] In order to avoid the above defects in the folder panels, the existing folder panel production will install edge protectors on the sides and corners of the folder panels to achieve the protection effect on the folder panels. The edge protectors are usually metal strip-shaped bands initially. The strip-shaped bands are relatively long and are coiled into rolls. They are installed on the folders through fixed-length shearing, bending, and folding and squeezing. However, the existing edge protector installation mostly adopts manual or semi-automatic installation, and it is impossible to install edge protectors on the two corners of the folder panel simultaneously at one time, and the overall production efficiency is relatively low. At the same time, manual installation is extremely prone to offset of the installation position, resulting in poor installation accuracy and affecting the overall product quality. Summary of the Invention

[0046] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0047] Please refer to Figure 1 and 2 As shown, the present invention is a fully automatic edge protector, including a feeding mechanism 1 and two edge pressing mechanisms 2; the feeding mechanism 1 includes a feeding frame 101; one end of the feeding frame 101 is welded or bolted with an edge pressing frame 102, and the feeding frame 101 and the edge pressing frame 102 are distributed in a T shape.

[0048] As Figure 2 - 8 shown, the feeding frame 101 includes a bottom plate; a power shaft 4 and a transmission shaft 5 are rotatably connected to the upper surface of the bottom plate through bearing seats; the power shaft 4 and the transmission shaft 5 are connected by bevel gears; the power shaft 4 is located inside the edge pressing frame 102 and is distributed in a T shape with the transmission shaft 5, and the power shaft 4 is connected with a driving device, the driving device is a motor, the motor is fixedly connected with the edge pressing frame 102 and is connected with the power shaft 4 by belt drive or chain drive. A laminated plate 1002 is welded inside the feeding frame 101; side baffles 103 are fixedly connected to both opposite sides of the feeding frame 101; the feeding frame 101 is fixedly connected with a limiting plate 1010 and two lower pressing plates 1011 through a rectangular plate; a plurality of rollers are rotatably connected to the side surfaces of the lower pressing plates 1011.

[0049] An inlet shaft 104 is rotatably connected to the upper surface of the bottom plate, a rectangular rod 105 is slidably connected through a sliding sleeve, a pushing rod 106 and a discharging rod 107 are hinged, and a vertical plate 108 is fixedly connected; a cam rod 109 and a blanking rod 110 are rotatably connected to the side surface of the vertical plate 108.

[0050] A pushing frame 11 and two pull rods 21 are slidably connected to the upper surface of the laminated plate 1002 through a guide rail-slider mechanism; a support rod 31 is fixedly connected to the upper surface of the laminated plate 1002; an installation rod 41 is slidably connected to one side of the laminated plate 1002 close to the edge pressing frame 102, and the installation rod 41 slides in the vertical direction; a conveying device 51 is arranged on the upper surface of the laminated plate 1002; the other end of the conveying device 51 is connected with the edge pressing frame 102.

[0051] The two pull rods 21 are symmetrically arranged relative to the pushing rack 11; the support rod 31 is located above the pushing rack 11; the support rod 31 is fixedly connected with a baffle 310, and the baffle 310 is arranged in parallel with the limiting plate 1010; the folder panel is placed on the support rod 31 and is limited front and back by the baffle 310 and the limiting plate 1010, and is limited left and right by the side baffles 103 on both sides. Moreover, the distance between the lower surface of the limiting plate 1010 and the upper surface of the support rod 31 is greater than or equal to the thickness of one folder panel but less than the thickness of two folder panels, that is, only one folder panel can pass through below the limiting plate 1010.

[0052] On the circumferential side of the transmission shaft 5, an inlet cylindrical cam 501, a pushing cylindrical cam 502, a blanking cam 503, and an end face cam 504 are fixedly connected in sequence in a direction away from the power shaft 4.

[0053] The inlet shaft 104 is matched with the inlet cylindrical cam 501 through a follower; both ends of the inlet shaft 104 are fixedly connected with a lever 1041; the lever 1041 is connected to the pull rod 21 through a connecting rod for enabling the pull rod 21 to perform a reciprocating motion; the upper surface of the pull rod 21 is fixedly connected with a mounting block 210; the upper surface of the mounting block 210 is hinged with a check block 211 for driving the check block 211 to push the folder panel through the pull rod 21 to achieve feeding.

[0054] Among them, as Figure 10 shown, a limiting card slot 2110 is formed on one side of the check block 211 close to the edge pressing rack 102; a compression spring 2111 is connected between the check block 211 and the mounting block 210 for keeping the side of the limiting card slot 2110 of the check block 211 in a raised state.

[0055] The rectangular rod 105 is matched with the pushing cylindrical cam 502 through a follower; the rectangular rod 105 is connected to the pushing rod 106 through a connecting rod; the upper end of the pushing rod 106 penetrates through the layer board 1002 and is connected to the pushing rack 11 through a connecting rod for enabling the pushing rack 11 to perform a linear reciprocating motion.

[0056] One end of the cam rod 109 is matched with the blanking cam 503 through a follower, and the other end is connected to the blanking rod 110 through a connecting rod; one end of the blanking rod 110 is connected to the mounting rod 41 through a connecting rod for enabling the mounting rod 41 to perform an up-and-down reciprocating motion; a blanking plate 410 is slidably connected to the upper surface of the mounting rod 41.

[0057] The discharging rod 107 is matched with the end face cam 504 through a follower; the upper end of the discharging rod 107 penetrates through the layer board 1002 and is connected to the blanking plate 410 through a connecting rod for enabling the blanking plate 410 to perform a reciprocating motion in the horizontal direction. A suction cup can be installed on the blanking plate 410 to realize the adsorption and fixation of the folder panel 8.

[0058] As Figure 9As shown in the figure, two pusher plates 113 and several groups of rolling wheels 111 are symmetrically arranged on the upper surface of the pusher frame 11; a pusher block 1100 is hinged on the upper surface of the pusher plate 113; the pusher plate 113 drives the pusher block 1100, and the folder panel is pushed to the position of the check block 211 through the pusher block 1100. Among them, one side of the pusher block 1100 close to the edge pressing frame 102 is a wedge-shaped structure, and a V-shaped groove 1101 is provided on the inclined surface of the wedge-shaped structure; a pressure rod 112 is fixedly connected to the upper surface of the pusher plate 113; one end of the pressure rod 112 is located above the pusher block 1100 and is a wedge-shaped structure;

[0059] A return spring 1120 is connected between the pusher block 1100 and the pressure rod 112, which is used to keep the side of the V-shaped groove 1101 of the pusher block 1100 in a lifted state, and the upper surface of the pusher block 1100 abuts against the lower surface of the pressure rod 112; roller bearings 1102 are rotatably connected to both sides of the pusher block 1100.

[0060] The transmission shaft 5 rotates, drives the pusher frame 11 to move forward through the pusher cylindrical cam 502, the rectangular rod 105 and the pusher rod 106, and uses the V-shaped groove 1101 on the pusher block 1100 to catch the side of the folder panel 8, so as to push the folder panel 8 from below the limit plate 1010 towards the edge pressing frame 102. When the folder panel 8 is pushed past the check block 211, as the transmission shaft 5 rotates, the pusher frame 11 returns. At this time, the limit card slot 2110 on the check block 211 catches the side of the folder panel 8, so that the folder panel 8 will not be taken back by the pusher frame 11, and the pusher block 1100 is rotatable, and it can return better from below the folder panels 8 stacked on the support rod 31 through the roller bearings 1102. During the return process of the pusher frame 11, the transmission shaft 5 rotates, and the check block 211 is pulled forward through the feed cylindrical cam 501, the feed shaft 104 and the pull rod 21, so as to further push the folder panel 8 towards the edge pressing mechanism 2.

The coiled strip is placed between two adjacent side plates 301 for storing materials and located on the rotating wheels 302, and the strip is limited by the stop rod 303, so that the strip rotates under the action of the rotating wheels 302, facilitating the pulling out of the strip. At the same time, two limit groove plates 307 are fixedly connected to the side of the plate frame; rectangular grooves are formed on the opposite surfaces of the two limit groove plates 307; a tensioning ring 308 is fitted in the gap between the two rectangular grooves. After the strip is pulled out, it bypasses the sheave group 305 once, passes under the tensioning ring 308, and passes through the sheave group 305 and the guide wheel 306. Under the action of the gravity of the tensioning ring 308, the strip is naturally tensioned, and during the conveying process, the tensioning ring 308 can be lifted, so that a large tensile force will not be generated on the strip, avoiding the occurrence of fracture or deformation of the strip.

[0065] One end of the camshaft 6 penetrates through and is installed on the side plate 201, and is fixedly connected with a driven wheel 6001; the driven wheel 6001 is in transmission connection with the transition wheel 207; so that the camshaft 6 and the transmission shaft 5 can rotate synchronously.
