DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0027] The following is combined with Figure 1 To Attachment Figure 6 And specific embodiments describe the present invention in detail.

[0028] like Figures 1 to 4 As shown, the utility model provides a feeding device, including a support frame 1, which is placed on a side close to the feed port of the horizontal and vertical slitting machine. A conveying frame 2 is fixedly connected to the top of the support frame 1, and the conveying frame 2 is connected to a grabbing and conveying mechanism 3.

[0029] The grabbing and conveying mechanism 3 grabs the material to be cut, and then conveys the grabbed material to the horizontal and vertical slitting machine. The horizontal knife of the horizontal and vertical slitting machine first cuts the material into strips, and then the strip material is conveyed in the horizontal and vertical slitting machine for subsequent cutting work.

[0030] By grabbing the material and conveying it into the horizontal and vertical slitting machine, the possibility of the material slipping or deflecting when entering the horizontal and vertical slitting machine can be reduced, and when the horizontal knife of the horizontal and vertical slitting machine cuts the material, the grabbing and conveying mechanism 3 can fix the material, further reducing the possibility of the material slipping or deflecting, and will not affect the cutting of the material, thereby improving the cutting accuracy and thus improving the quality of the product.

[0031] The grabbing and conveying mechanism 3 includes three first linear actuators 31 and three second linear actuators 32, and the first linear actuators 31 and the second linear actuators 32 are staggeredly distributed in sequence along the width direction of the conveying frame 2. The first linear actuator 31 can be a component capable of realizing linear motion, such as a cylinder, a hydraulic cylinder, or an electric telescopic rod, and the second linear actuator 32 can be a component capable of realizing linear motion, such as a cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0032] The first linear drive 31 is connected to a first drive assembly 33 for driving the first linear drive 31 to reciprocate along the material feeding direction, and the first drive assembly 33 drives the three first linear drives 31 to move synchronously. The second linear drive 32 is connected to a second drive assembly 34 for driving the second linear drive 32 to reciprocate along the material feeding direction, and the second drive assembly 34 drives the three second linear drives 32 to move synchronously.

[0033] Each first linear actuator 31 is fixedly connected to a first support plate 311 at the bottom, and the piston rod of the first linear actuator 31 passes through the first support plate 311 and is fixedly connected to a first connecting plate 312, and the first connecting plate 312 is fixedly connected to a plurality of first suction cups 313. Each second linear actuator 32 is fixedly connected to a second support plate 321 at the bottom, and the piston rod of the second linear actuator 32 passes through the second support plate 321 and is fixedly connected to a second connecting plate 322, and a plurality of second suction cups 323 are fixedly connected to the lower surface of the second connecting plate 322.

[0034] When it is necessary to grab the material for loading, the piston rod of the first linear actuator 31 extends, the first suction cup 313 contacts the material, the first suction cup 313 absorbs and fixes the material, the piston rod of the first linear actuator 31 contracts, and the material is lifted. The first driving assembly 33 drives the first linear actuator 31 to move to the side close to the horizontal and vertical slitting machine, and delivers the material into the horizontal and vertical slitting machine.

[0035] The horizontal blade of the horizontal and vertical slitting machine completes a stroke of cutting the material. At this time, the piston rod of the second linear actuator 32 extends, and the second suction cup 323 contacts the material, and the second suction cup 323 absorbs and fixes the material. After the second suction cup 323 absorbs and fixes the material, the first suction cup 313 no longer absorbs the material, and the piston rod of the first linear actuator 31 contracts, driving the first suction cup 313 to release the fixation of the material, and the first driving component 33 drives the first linear actuator 31 to move a distance away from the horizontal and vertical slitting machine. The second driving component 34 drives the second linear actuator 32 to move a distance toward the side close to the horizontal and vertical cutting machine, and the material continues to be fed into the horizontal and vertical slitting machine, and the horizontal blade continues to cut the material and completes a stroke.

[0036] The piston rod of the first linear actuator 31 extends again, and the first suction cup 313 contacts the material, and the first suction cup 313 fixes the material. After the first suction cup 313 adsorbs and fixes the material, the second suction cup 323 no longer adsorbs the material, and the piston rod of the second linear actuator 32 contracts, driving the second suction cup 323 to release the fixation of the material, and the second driving component 34 drives the second linear actuator 32 to move a distance away from the horizontal and vertical slitting machine. The first driving component 33 drives the first linear actuator 31 to move a distance close to the horizontal and vertical cutting machine, and the material continues to be fed into the horizontal and vertical slitting machine, and the horizontal knife continues to cut the material to complete a stroke, and the above movement process is repeated until the adsorbed material is cut.

[0037] The first suction cup 313 and the second suction cup 323 alternately absorb the material and send the material into the horizontal and vertical slitting machine, which can reduce the possibility of the material slipping or deflecting during the material feeding and cutting process, and improve the cutting quality of the material.

[0038] By controlling the distance that the first linear drive 31 and the second linear drive 32 drive the material to move toward the side close to the horizontal and vertical slitting machine each time, the width of the cut material can be adjusted and controlled, and the specifications of the cut material can be guaranteed to be uniform, thereby further improving the cutting quality.

A first slider 338 is fixedly connected to the side of the first fixing plate 336 close to the first slide rail 335, and the first slider 338 is slidably connected to the first slide rail 335.

The output shaft of the first motor 331 rotates in the opposite direction, and the first linear drive 31 can be driven by the first belt 334 to move toward the side away from the horizontal and vertical slitting machine.

[0042] The second driving assembly 34 includes a second motor 341, and the second motor 341 is fixedly connected to the upper surface of the conveying frame 2. Two groups of second support seats 342 are fixedly connected to the upper surface of the conveying frame 2, and the number of each group of second support seats 342 is three. Each second support seat 342 is rotatably connected to a second pulley 343, and a second belt 344 is connected between two corresponding second pulleys 343 along the material conveying direction. The output shaft of the second motor 341 passes through the three second pulleys 343 near the second motor 341, and the output shaft of the second motor 341 is fixedly connected to the second pulley 343.

[0043] The conveyor frame 2 is fixedly connected with three second slide rails 345, which are arranged corresponding to the second belt 344 and are placed below the second belt 344.

A second slider 348 is fixedly connected to the side of the third fixing plate 346 close to the second slide rail 345, and the second slider 348 is slidably connected to the second slide rail 345.

[0044] The output shaft of the second motor 341 drives the second pulley 343 to rotate, the second pulley 343 drives the second belt 344 to rotate, the second belt 344 drives the second linear drive 32 to move toward the side close to the horizontal and vertical slitting machine, and the second linear drive 32 drives the material into the horizontal and vertical slitting machine for cutting through the second suction cup 323. The output shaft of the second motor 341 rotates in the opposite direction, and the second linear drive 32 can be driven by the second belt 344 to move toward the side away from the horizontal and vertical slitting machine.

[0045] The first support plate 311 and the second support plate 321 are both fixedly connected with the guide rod 4, and the guide rod 4 is slidably plugged with the corresponding first support plate 311 and the second support plate 321 respectively. When the piston rods of the first linear drive 31 and the second linear drive 32 are extended or contracted, the guide rod 4 increases the stability of the piston rods of the first linear drive 31 and the second linear drive 32 during movement, thereby increasing the stability in the process of driving the material to move upward.

[0046] like Figures 1 to 6 As shown, a support platform 5 is provided inside the support frame 1, and a lifting assembly 6 is provided between the support platform 5 and the support frame 1, and the support platform 5 and the support frame 1 are connected through the lifting assembly 6. First, the materials to be cut are stacked on the upper surface of the support platform 5, and as the uppermost layer of materials are adsorbed and transported into the horizontal and vertical slitting machine for cutting, the lifting assembly 6 drives the lifting platform to gradually rise, so that the uppermost layer of materials is placed close to the first suction cup 313 and the second suction cup 323, shortening the extension distance of the piston rods of the first linear actuator 31 and the second linear actuator 32, and improving the feeding efficiency of the materials.

[0047] The lifting assembly 6 includes a first fixed seat 61 fixedly connected to the bottom of the support frame 1, a third motor 62 is fixedly connected to the upper surface of the first fixed seat 61, and the output shaft of the third motor 62 is fixedly connected to the first bevel gear 63.

When the support platform 5 rises or falls, the guide columns 7 guide the support platform 5 to increase the stability of the support platform 5 during movement.

[0052] The support frame 1 is fixedly connected with a plurality of limit rods 8, and the plurality of limit rods 8 are arranged along the length direction of the support frame 1. When the material is placed on the support platform 5, the limit rods 8 can block the material, so that the material placed on the support platform 5 abuts against the limit rods 8, thereby preventing the possibility of the material being placed off-center during the process of placing the material on the support platform 5.

[0053] A protective cover 9 is fixedly connected to the upper surface of the support frame 1 , and the first motor 331 and the second motor 341 are placed in the protective cover 9 , which reduces the possibility of workers accidentally touching the first motor 331 and the second motor 341 and improves safety.

The first motor 331 starts and drives the first linear actuator 31 to move toward the side close to the horizontal and vertical slitting machine, and delivers the material into the horizontal and vertical slitting machine.

[0056] The horizontal blade of the horizontal and vertical slitting machine completes a stroke of cutting the material. At this time, the piston rod of the second linear actuator 32 extends, and the second suction cup 323 absorbs and fixes the material. The first suction cup 313 no longer absorbs the material, the piston rod of the first linear actuator 31 contracts, and the output shaft of the first motor 331 rotates in the opposite direction, thereby driving the first linear actuator 31 to move a distance away from the horizontal and vertical slitting machine.
