Description

Technical Field

[0001] This invention relates to the field of paper cup gripping technology, specifically to a paper cup gripping and collecting device. Background Technology

[0002] Paper cup gripping devices are commonly used in automated production lines for paper cup processing. They automatically grip paper cups for further operations such as labeling and inspection. This type of device improves production efficiency, reduces manual labor, and ensures accuracy and consistency in operations.

[0003] Because paper cups are made of relatively soft material, they are easily damaged when gripped with ordinary clamps, which may deform or break them. Therefore, a gripping device that can fully protect paper cups is needed. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a paper cup gripping and collecting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A paper cup gripping and collecting device includes a fixed plate, the bottom of which is equipped with an outer gripper and an inner gripper;

[0007] The top of the outer gripper is hinged to the fixed plate, and the middle part of the outer gripper has an inclined angle.

[0008] The top of the inner gripper is slidably connected to the middle of the outer gripper. Under the action of gravity, the inner gripper can slide towards the outer gripper. The inner gripper and the outer gripper work together to clamp the side wall of the paper cup.

[0009] By moving the fixed plate downwards, the outer gripper first abuts against the outer wall of the paper cup, while the inner gripper is also pressed against the inner wall of the paper cup. When the paper cup needs to be lifted, since the center of the outer gripper is near the outside of the paper cup, the outer gripper will move towards the paper cup under the action of gravity. Since the top of the inner gripper slides and connects with the middle inclined part of the outer gripper, the inner gripper slides towards the inner wall of the paper cup. Thus, through the combined action of the outer and inner grippers, the paper cup is clamped tightly. And without the need for other driving devices, the paper cup is clamped tightly by gravity alone, which fully protects the paper cup from damage.

[0010] Preferably, a sliding groove is provided at the middle of the outer gripper at an inclined angle, a slider is fixedly connected to the top of the inner gripper, the slider is slidably connected to the sliding groove, a hinge groove is provided in the middle of the fixed disk, a hinge post is connected to the top of the outer gripper, the hinge post is hinged to the hinge groove, and the outer gripper rotates around the hinge groove on the fixed disk.

[0011] Preferably, the outer gripper has a folding groove on the side near the paper cup, and a support plate is provided inside the folding groove. The bottom of the support plate is hinged to the bottom of the folding groove by a torsion spring. When the outer gripper clamps the paper cup, the top of the support plate abuts against the lower outer edge of the top of the paper cup.

[0012] By providing a support plate on the inner side of the outer gripper, when the outer gripper abuts against the outer wall of the paper cup (100), the top of the support plate can abut against the lower outer edge of the top of the paper cup, thereby providing sufficient support and preventing the paper cup from falling.

[0013] Preferably, the bottom of the outer gripper is provided with a first inclined surface, which extends outward toward the paper cup. A pad is provided on the side of the inner gripper near the outer gripper. The pad is made of rubber. When the inner gripper clamps the paper cup, the pad abuts against the inner wall of the paper cup.

[0014] Preferably, an adjusting rod is installed on the inner wall of the hinge groove, the adjusting rod is threadedly connected to the fixed plate, and the other end of the adjusting rod extends to the outside of the fixed plate;

[0015] By rotating the adjusting rod, the position of the adjusting rod changes, thereby reducing the angle at which the outer gripper can rotate. This changes the squeezing limit of the outer gripper on the paper cup, preventing the outer gripper from causing severe deformation of the paper cup. It also allows the outer gripper to adapt to paper cups with different outer diameters.

[0016] Preferably, a second inclined surface is provided on the inner side of the top of the outer gripper, and a limiting rod is provided below the second inclined surface. A sliding ring is connected to the bottom of the limiting rod, and the sliding ring is slidably connected to the top of the fixed plate. A first spring is connected between the sliding ring and the top of the fixed plate. When the bottom of the outer gripper expands towards the outside of the paper cup, the second inclined surface at the top of the outer gripper moves towards the limiting rod, causing the limiting rod to move downward.

[0017] Preferably, a lifting block is provided below the fixed plate, and a rope is connected to the bottom of the lifting block. The other end of the rope is connected to the top of the inner gripper. When the lifting block rises, it can drive the inner gripper away from the outer gripper. The top of the lifting block is connected to the fixed plate through an electric telescopic rod.

[0018] Preferably, the bottom of the fixed plate is also connected to a negative pressure tube, and a telescopic tube is provided below the negative pressure tube. The telescopic tube is slidably connected to the outer wall of the negative pressure tube. The telescopic tube is connected to the outer wall of the negative pressure tube through a second spring. A suction cup is connected to the bottom of the telescopic tube. The bottom of the suction cup abuts against the bottom of the inner wall of the paper cup. The inside of the lifting block is provided with a cavity. The inside of the negative pressure tube communicates with the cavity. The top of the lifting block is connected to a suction tube. The top of the suction tube is connected to a negative pressure pump.

[0019] When the electric telescopic rod lowers the lifting block to its lowest position, the inner gripper can slide to the position closest to the inner wall of the paper cup. At the same time, when the lifting block is at its lowest position, the negative pressure tube at its bottom also moves downward, and the suction cup at the bottom of the telescopic tube abuts against the bottom of the inner wall of the paper cup. At this time, the negative pressure pump works to draw a vacuum inside the negative pressure tube, the telescopic tube, and the suction cup, thereby sucking the paper cup in place and making it less likely for the paper cup to fall off.

[0020] Preferably, a sliding block is connected to the top of the fixed plate, and a slide rail is provided above the sliding block. The sliding block is slidably connected to the slide rail, and the slide rail is fixedly installed on the paper cup production line.

[0021] Compared with the prior art, the present invention provides a paper cup gripping and collecting device, which has the following beneficial effects:

[0022] 1. This invention moves the fixed plate downwards, causing the outer clamping claw to first abut against the outer wall of the paper cup, while the inner clamping claw is also pressed against the inner wall of the paper cup. When the paper cup needs to be lifted, since the center of the outer clamping claw is near the outside of the paper cup, the outer clamping claw will move towards the paper cup under the action of gravity. Since the top of the inner clamping claw is slidably connected to the inclined middle part of the outer clamping claw, the inner clamping claw slides towards the inner wall of the paper cup. Thus, the paper cup is clamped tightly by the combined action of the outer and inner clamping claws. Without the need for other driving devices, the paper cup is clamped by gravity alone, which fully protects the paper cup from damage.

[0023] 2. This invention changes the position of the adjusting rod by rotating it, thereby reducing the angle at which the outer gripper can rotate. This changes the squeezing limit of the outer gripper on the paper cup, preventing the outer gripper from causing severe deformation of the paper cup. It also allows the outer gripper to adapt to paper cups with different outer diameters.

[0024] 3. This invention uses an electric telescopic rod to drive the lifting block to descend. When the lifting block descends to its lowest point, the inner gripper can slide to the position closest to the inner wall of the paper cup. At the same time, when the lifting block descends to its lowest point, the negative pressure tube at its bottom also moves downward, and the suction cup at the bottom of the telescopic tube abuts against the bottom of the inner wall of the paper cup. At this time, the negative pressure pump works to draw a vacuum inside the negative pressure tube, the telescopic tube, and the suction cup, thereby sucking the paper cup in place and making it less likely for the paper cup to fall off.

[0025] 4. The present invention provides a support plate on the inner side of the outer gripper, so that when the outer gripper abuts against the outer wall of the paper cup (100), the top of the support plate abuts against the lower outer edge of the top of the paper cup, thereby providing sufficient support and preventing the paper cup from falling.

Implementation Example

[0036] See Figure 1-3 This embodiment discloses a paper cup gripping and collecting device, including a fixed plate 210, the bottom of which is equipped with an outer gripper 220 and an inner gripper 230;

[0037] The top of the outer gripper 220 is hinged to the fixed disk 210, and the middle part of the outer gripper 220 has an inclined angle.

[0038] The top of the inner gripper 230 is slidably connected to the middle of the outer gripper 220. Under the action of gravity, the inner gripper 230 can slide towards the outer gripper 220. The inner gripper 230 and the outer gripper 220 work together to clamp the side wall of the paper cup 100.

[0039] By moving the fixed plate 210 downwards, the outer gripper 220 first abuts against the outer wall of the paper cup 100, while the inner gripper 230 is also pressed against the inner wall of the paper cup 100. When the paper cup 100 needs to be lifted, since the center of the outer gripper 220 is close to the outside of the paper cup 100, the outer gripper 220 will move towards the paper cup 100 under the action of gravity. Since the top of the inner gripper 230 is slidably connected to the middle inclined part of the outer gripper 220, the inner gripper 230 slides towards the inner wall of the paper cup 100. Thus, through the combined action of the outer gripper 220 and the inner gripper 230, the paper cup 100 is clamped. Without the use of other driving devices, the paper cup 100 is clamped by gravity alone, which fully protects the paper cup 100 from damage.

[0040] like Figure 4 , Figure 5 As shown, in one possible embodiment, the outer gripper 220 has a groove 225 at an inclined angle in the middle, the inner gripper 230 has a slider 226 fixedly connected to the top, the slider 226 is slidably connected to the groove 225, the fixed disk 210 has a hinge groove 229 in the middle, the outer gripper 220 has a hinge post 228 connected to the top, the hinge post 228 is hinged to the hinge groove 229, and the outer gripper 220 rotates around the hinge groove 229 on the fixed disk 210.

[0041] like Figure 3 As shown, the outer gripper 220 has a folding groove 222 on the side near the paper cup 100. A support plate 221 is provided inside the folding groove 222. The bottom of the support plate 221 is hinged to the bottom of the folding groove 222 by a torsion spring 223. When the outer gripper 220 clamps the paper cup 100, the top of the support plate 221 abuts against the lower outer edge of the top of the paper cup 100.

[0042] By providing a support plate 221 on the inner side of the outer gripper 220, when the outer gripper 220 abuts against the outer wall of the paper cup 100, the top of the support plate 221 can abut against the lower outer edge of the top of the paper cup 100, thereby providing sufficient support and preventing the paper cup 100 from falling.

[0043] like Figure 4As shown, the bottom of the outer gripper 220 is provided with a first inclined surface 224, which extends outward toward the paper cup 100. The inner gripper 230 is provided with a pad on the side near the outer gripper 220. The pad is made of rubber. When the inner gripper 230 clamps the paper cup 100, the pad abuts against the inner wall of the paper cup 100.

[0044] like Figure 6 As shown, an adjusting rod 310 is installed on the inner wall of the hinge groove 229. The adjusting rod 310 is threadedly connected to the fixed plate 210, and the other end of the adjusting rod 310 extends to the outside of the fixed plate 210.

[0045] By rotating the adjusting rod 310, the position of the adjusting rod 310 is changed, thereby reducing the rotatable angle of the outer gripper 220. This changes the squeezing limit of the outer gripper 220 on the paper cup 100, preventing the outer gripper 220 from causing severe deformation of the paper cup 100. It also allows the outer gripper 220 to adapt to paper cups 100 with different outer diameters.

[0046] like Figure 7 , Figure 8 As shown, in one possible embodiment, a second inclined surface 227 is provided on the inner side of the top of the outer gripper 220, and a limiting rod 340 is provided below the second inclined surface 227. A sliding ring 320 is connected to the bottom of the limiting rod 340. The sliding ring 320 is slidably connected to the top of the fixed plate 210. A first spring 330 is connected between the sliding ring 320 and the top of the fixed plate 210. When the bottom of the outer gripper 220 expands outward toward the paper cup 100, the second inclined surface 227 at the top of the outer gripper 220 moves toward the limiting rod 340, causing the limiting rod 340 to move downward.

[0047] like Figure 8 , Figure 9 As shown, in one possible embodiment, a lifting block 410 is provided below the fixed plate 210. The bottom of the lifting block 410 is connected to a rope 420, and the other end of the rope 420 is connected to the top of the inner gripper 230. When the lifting block 410 rises, it can drive the inner gripper 230 away from the outer gripper 220. The top of the lifting block 410 is connected to the fixed plate 210 through an electric telescopic rod 430.

[0048] like Figure 9As shown, the bottom of the fixed plate 210 is also connected to a negative pressure tube 520, and a telescopic tube 530 is provided below the negative pressure tube 520. The telescopic tube 530 is slidably connected to the outer wall of the negative pressure tube 520. The telescopic tube 530 is connected to the outer wall of the negative pressure tube 520 through a second spring 540. A suction cup 550 is connected to the bottom of the telescopic tube 530. The bottom of the suction cup 550 abuts against the bottom of the inner wall of the paper cup 100. The inside of the lifting block 410 is provided with a cavity. The inside of the negative pressure tube 520 communicates with the cavity. The top of the lifting block 410 is connected to a suction tube 510, and the top of the suction tube 510 is connected to a negative pressure pump.

[0049] When the electric telescopic rod 430 drives the lifting block 410 to its lowest position, the inner gripper 230 can slide to the position closest to the inner wall of the paper cup 100. At the same time, when the lifting block 410 descends to its lowest position, the negative pressure tube 520 at its bottom also moves downward, and the suction cup 550 at the bottom of the telescopic tube 530 abuts against the bottom of the inner wall of the paper cup 100. At this time, the negative pressure pump works to draw a vacuum inside the negative pressure tube 520, the telescopic tube 530, and the suction cup 550, thereby sucking the paper cup 100 in place and making it less likely for the paper cup 100 to fall off.

[0050] like Figure 1 As shown, a sliding block 610 is connected to the top of the fixed plate 210, and a slide rail 620 is provided above the sliding block 610. The sliding block 610 is slidably connected to the slide rail 620, and the slide rail 620 is fixedly installed on the paper cup production line.
