Description

Technical Field

[0001] This utility model relates to the technical field of plastic bucket processing equipment, specifically to a robotic arm for a plastic bucket labeling machine. Background Technology

[0002] Labeling is an important process in the production and processing of plastic buckets, and the performance of the labeling machine robot arm, as the key execution component of the labeling process, directly affects the labeling efficiency and quality.

[0003] Currently, traditional plastic bucket labeling machine robots typically employ a fixed structure design, meaning that the positioning components that work with the plastic buckets are integrated with the robot body. When labeling plastic buckets of different sizes is required, the entire robot must be replaced or the positioning components must be disassembled and adjusted in a complex manner. This process is cumbersome and time-consuming, severely impacting production efficiency. Therefore, a new type of robot for plastic bucket labeling machines is proposed. Utility Model Content

[0004] This utility model proposes a robotic arm for a plastic bucket labeling machine. When changing plastic buckets of different sizes, simply pull the pull ring to move the stabilizing rod and the moving block, so that the limiting block is disengaged from the limiting groove. This allows for quick separation of the connecting plate and the fixing plate, and replacement of the fixing plate with the corresponding first slot. The operation is convenient and efficient, significantly improving the equipment's adaptability to different specifications of plastic buckets and its changeover efficiency.

[0005] According to one aspect, at least one embodiment of the present invention provides a robotic arm for a plastic bucket labeling machine, comprising: a labeling machine robotic arm, one end of which is threadedly connected to a connecting plate, one end of which is provided with a fixing plate, a first slot being provided at the top of the fixing plate, a plastic bucket body being provided at the bottom of the fixing plate, the top of which is inserted into the first slot, a second slot being provided inside the fixing plate, and an insert block being fixedly connected to the bottom of the connecting plate, the connecting plate being fixed to the fixing plate by the insert block being inserted into the second slot.

[0006] For example, at least one embodiment of the present invention provides a robotic arm for a plastic bucket labeling machine, which further includes: the inside of the first slot is in contact with the outer wall of the plastic bucket body, and a rubber pad is adhered to the inner wall surface of the first slot.

[0007] For example, at least one embodiment of the present invention provides a robotic arm for a plastic bucket labeling machine, which further includes: a limiting groove is provided in the connecting plate, a moving groove is provided inside the fixing plate, a moving block is movably disposed inside the moving groove, a limiting block is fixedly connected to one end of the moving block, and the limiting block is inserted into the limiting groove through the moving groove.

[0008] For example, at least one embodiment of the present invention provides a robotic arm for a plastic bucket labeling machine, which further includes: a stabilizing groove is provided in the moving groove, a stabilizing rod is slidably connected inside the stabilizing groove, one end of the stabilizing rod is fixedly connected to the moving block, and the other end of the stabilizing rod is fixedly connected to a pull ring.

[0009] For example, at least one embodiment of the present invention provides a robotic arm for a plastic bucket labeling machine, which further includes: the pull ring is arranged in an arc shape, and the outer wall of the pull ring is fixedly provided with anti-slip texture.

[0010] For example, at least one embodiment of the present invention provides a robotic arm for a plastic bucket labeling machine, which further includes: a spring installed inside the moving groove, one end of the spring being fixedly connected to the moving block, and the other end of the spring being fixedly connected to the moving groove.

[0011] For example, at least one embodiment of the present invention provides a robotic arm for a plastic bucket labeling machine, which further includes: the limiting groove is symmetrically arranged on the connecting plate, and the outer wall of the limiting block and the inner wall of the limiting groove are in contact with each other.

[0012] For example, at least one embodiment of the present invention provides a robotic arm for a plastic bucket labeling machine, which further includes: a connecting rod fixedly connected to the outer wall of the connecting plate, a rubber handle fixedly connected to the outer wall of the connecting rod, a stabilizing block fixedly connected to the outer wall of the rubber handle, an auxiliary pad adhered to the outer wall of the stabilizing block, and the outer wall of the auxiliary pad being in contact with the inner wall of the plastic bucket body.

[0013] The working principle and beneficial effects of this utility model are as follows: When changing plastic buckets of different sizes, simply pull the pull ring to move the stabilizing rod and the moving block, causing the limiting block to disengage from the limiting groove, thus quickly separating the connecting plate and the fixing plate. Replace the fixing plate with the corresponding first slot. The operation is convenient and efficient, significantly improving the equipment's adaptability to different specifications of plastic buckets and the efficiency of changing models. A connecting plate is threaded to the end of the labeling machine's robotic arm. The bottom of the connecting plate has an insert block that engages with the second slot of the fixing plate to achieve initial fixation. The moving block in the moving groove drives the limiting block to insert into the limiting groove of the connecting plate, forming a double fixing structure. This effectively ensures the stability of the connection between the connecting plate and the fixing plate, prevents the insert block from coming out or sliding during the labeling process, and ensures stable operation of the device.

[0014] In addition, the rubber pads bonded to the inner wall of the first slot ensure that the top of the plastic bucket fits tightly with the slot, generating greater friction and preventing slippage during labeling rotation, thus ensuring even and flat label application. The connecting rods on the outer wall of the connecting plate, the stabilizing blocks supported by the rubber handles, and the auxiliary pads are bonded from inside the bucket to prevent deformation of the plastic bucket under stress, further improving the stability of labeling quality and balancing production efficiency with labeling effect.

[0023] Refer to the instruction manual appendix Figure 1-4A robotic arm for a plastic bucket labeling machine includes a labeling robot arm 1. One end of the labeling robot arm 1 is threadedly connected to a connecting plate 2. One end of the connecting plate 2 is provided with a fixing plate 3. The top of the fixing plate 3 has a first slot 5. The bottom of the fixing plate 3 is provided with a plastic bucket body 4. The top of the plastic bucket body 4 is inserted into the first slot 5. The inside of the fixing plate 3 has a second slot 6. The bottom of the connecting plate 2 is fixedly connected to an insert block 7. The inside of the connecting plate 2 is fixed to the fixing plate 3 through the insert block 7 inserted into the second slot 6. Initial positioning is achieved through the insertion and engagement of the slots with the bucket body. The fixing plate 3 has a second slot 6 vertically formed inside. The bottom of the connecting plate 2 has an integrally formed insert 7 that matches the size of the second slot 6. The connecting plate 2 is inserted into the second slot 6 through the insert 7, thus achieving initial fixation with the fixing plate 3. When the labeling machine is in use, the labeling machine robot 1 drives the connecting plate 2 and the fixing plate 3 to press down synchronously through its own drive mechanism, thereby causing the first slot 5 of the fixing plate 3 to engage with the top of the plastic bucket body 4. At this time, the rotation drive component of the labeling machine robot 1 is activated, causing the fixing plate 3 to rotate synchronously. The fixing plate 3 then drives the plastic bucket body 4 through the engagement relationship between the first slot 5 and the plastic bucket body 4. The body 4 rotates stably. At this time, the labeling operation of the labeling machine can be completed through the coordinated operation of the label conveying, pasting and other supporting mechanisms. When it is necessary to replace the plastic bucket body 4 with a different size, the operator can quickly disassemble and install the fixing plate 3 to replace it with a fixing plate 3 with a first slot 5 corresponding to the size of the new plastic bucket body 4. This allows the plastic bucket body 4 of different sizes to accurately match the corresponding first slot 5, thereby satisfying the equipment's snap-fit ​​and fixing effect on plastic buckets of different specifications. This ensures that the equipment can still complete the labeling process normally after changing the bucket type, effectively improving the equipment's versatility and applicability.

[0024] Then, the shape and size of the inside of the first slot 5 are perfectly matched with the shape and size of the outer wall of the top of the plastic bucket body 4, ensuring that the inside of the first slot 5 and the outer wall of the plastic bucket body 4 can fit tightly together. In order to further improve the stability of the snap-fit, a rubber pad is bonded to the inner wall surface of the first slot 5 with strong adhesive. When the first slot 5 on the fixing plate 3 is inserted and snapped into the top position of the plastic bucket body 4, the outer wall of the plastic bucket body 4 contacts the rubber pad on the inner wall of the first slot 5. At this time, a large frictional force is generated between the plastic bucket body 4 and the first slot 5. This frictional force is used to reliably fix the plastic bucket body 4 in the first slot 5, avoiding relative displacement of the plastic bucket body 4 during rotation. At this time, the rotational power of the labeling machine robot 1 drives the fixing plate 3 to rotate. The fixing plate 3 drives the plastic bucket body 4 to rotate synchronously through the above-mentioned frictional force, which can ensure that the plastic bucket body 4 will not slip during the rotation of the labeling machine, thereby ensuring that the label can be evenly and flatly pasted on the outer wall of the plastic bucket body 4, improving the quality stability of labeling, and reducing the generation of defective products such as label skewing and wrinkles caused by slippage.

[0025] Subsequently, the connecting plate 2 has a limiting groove 9, and the fixed plate 3 has a moving groove 8. A moving block 10 is movably installed inside the moving groove 8. One end of the moving block 10 is fixedly connected to a limiting block 11. The limiting block 11 passes through the moving groove 8 and is inserted into the limiting groove 9. The moving block 10 inside the moving groove 8 can move horizontally under external force. When the moving block 10 moves, it will drive the limiting block 11 to move synchronously, so that the limiting block 11 can be accurately inserted into or disengaged from the limiting groove 9. When the limiting block 11 is inserted into the limiting groove 9, it can lock the relative position between the connecting plate 2 and the fixed plate 3, thereby ensuring the fixing effect of the insert 7 inside the second slot 6. This prevents the insert 7 from coming out of the second slot 6 or sliding relative to it during the operation of the labeling machine robot 1. This ensures that the fixed plate 3 and the connecting plate 2 can maintain a stable connection relationship when the labeling machine robot 1 is used, ensuring the normal operation of the entire device and avoiding interruption of the labeling process or a decrease in labeling quality due to loose connection.

[0026] Next, the moving slot 8 has a stabilizing slot 13. A stabilizing rod 14 is slidably connected inside the stabilizing slot 13. One end of the stabilizing rod 14 is fixedly connected to the moving block 10, and the other end of the stabilizing rod 14 is fixedly connected to a pull ring 15. When the fixing plate 3 needs to be replaced, the operator pulls the pull ring 15 with their finger. The pull ring 15 drives the stabilizing rod 14 to slide away from the limiting slot 9 inside the stabilizing slot 13. The stabilizing rod 14 then drives the moving block 10 to move synchronously inside the moving slot 8. When the moving block 10 moves, it causes the limiting block 11 to disengage from the limiting slot 9. At this time, the locking relationship between the connecting plate 2 and the fixing plate 3 is released. The operator can then pull the fixing plate 3 upward to disengage the insert 7 from the second slot 6, thereby separating the connecting plate 2 from the fixing plate 3 for replacement. The combination of the stabilizing groove 13 and the stabilizing rod can guide and limit the movement direction of the moving block 10, ensuring that the moving block 10 always moves in a horizontal direction, avoiding deviation or jamming of the moving block 10 during movement, and improving the convenience and smoothness of disassembly and assembly operations.

[0027] At this time, the pull ring 15 is arc-shaped, and the outer wall of the pull ring 15 is fixedly provided with anti-slip texture; this makes it easy for the operator's fingers to slip and pull, reducing finger fatigue during operation. At the same time, the outer wall of the pull ring 15 is pressed with uniformly distributed anti-slip texture by a mold; the anti-slip texture can increase the friction between the outer wall of the pull ring 15 and the operator's fingers, ensuring that even if the operator's hands are sweaty or oily, there will be no slippage when pulling the pull ring 15, improving the reliability and safety of operation, and enabling the operator to easily and stably complete the action of pulling the pull ring 15, thereby smoothly realizing the assembly and disassembly of the fixing plate 3.

[0028] Next, a spring 12 is installed inside the movable slot 8. One end of the spring 12 is fixedly connected to the movable block 10, and the other end is fixedly connected to the movable slot 8. When the fixed plate 3 needs to be removed, the operator pulls the pull ring 15 to move the movable block 10. The movable block 10 compresses the spring 12, causing the spring 12 to undergo elastic deformation and store elastic potential energy. After the fixed plate 3 is replaced, the operator releases the pull ring 15. At this time, the spring 12 releases the stored elastic potential energy. Through the elastic performance of the spring 12, the movable block 10 is pulled and reset towards the limiting slot 9. When the movable block 10 resets, it drives the limiting block 11 to move synchronously, so that the limiting block 11 is accurately inserted back into the limiting slot 9, thereby automatically completing the locking between the connecting plate 2 and the fixed plate 3. There is no need for the operator to manually adjust the position of the limiting block 11, which simplifies the replacement process of the fixed plate 3, improves the operating efficiency, and also ensures the precise fit between the limiting block 11 and the limiting slot 9, ensuring the locking effect.

[0029] Secondly, the limiting grooves 9 are symmetrically arranged on the connecting plate 2, and the outer wall of the limiting block 11 fits into the inner wall of the limiting groove 9. The two sets of symmetrically arranged limiting blocks 11 and limiting grooves 9 are simultaneously inserted and fixed, which can lock the relative position between the connecting plate 2 and the fixing plate 3 from two different positions. Compared with a single limiting structure, the fixing effect of this double limiting structure is more stable and reliable. It can effectively disperse the force generated during the labeling process, avoid damage to a single limiting point due to excessive force, extend the service life of the device, and further prevent relative shaking between the connecting plate 2 and the fixing plate 3, ensuring the stability of the entire device during operation.

[0030] Finally, a connecting rod 16 is fixedly connected to the outer wall of the connecting plate 2, a rubber handle 17 is fixedly connected to the outer wall of the connecting rod 16, a stabilizing block 18 is fixedly connected to the outer wall of the rubber handle 17, and an auxiliary pad 19 is adhesively attached to the outer wall of the stabilizing block 18. The outer wall of the auxiliary pad 19 is in contact with the inner wall of the plastic bucket body 4. The connecting rod 16 and the rubber handle 17 support the stabilizing block 18, ensuring that the stabilizing block 18 is held in a position corresponding to the inner wall of the plastic bucket body 4. The stabilizing block 18 and the auxiliary pad 19 work together to support the bucket body from the inside, ensuring that the inner wall of the plastic bucket body 4 has a reinforced and fixed effect, preventing the plastic bucket body 4 from deforming due to force during the rotation and labeling process. At the same time, the auxiliary pad 19 increases the friction between the stabilizing block 18 and the inner wall of the plastic bucket body 4, further improving the stability of the plastic bucket body 4 during rotation, preventing the bucket from shaking, thus ensuring the smooth progress of the labeling process and improving the accuracy and quality of labeling.
