Description

Technical Field

[0001] This utility model relates to the field of goods packaging technology, and in particular to an automatic stretch film feeding and packaging device. Background Technology

[0002] Stretch wrapping equipment, as a specialized automated equipment integrating automatic feeding and stretch wrapping functions, is widely used in core scenarios such as logistics warehousing, finished product outbound from manufacturing, and e-commerce distribution. Its core application is for palletized grouped goods, ensuring the safety and efficiency of goods flow through standardized packaging operations.

[0003] For example, Chinese Patent Publication No. CN208233419U discloses an automatic wrapping film device for kitchenware packaging boxes, including a base, a slide groove, and a fixed seat. Storage slots are provided on both sides of the base, and a motor is installed in the middle of the base. A worktable is connected to the upper part of the motor. The slide groove is opened on the upper surface of the worktable, and a compression spring rod is installed inside the slide groove. The fixed seat is connected to the base through a connecting rod, and a hard spring is connected to the right side of the connecting rod. A fixed rod is installed on the upper left side of the fixed seat, and a support rod is connected to the upper right side of the fixed seat. A slide rod is provided on the left side of the support rod, and a fixing screw is connected to the outside of the slide rod.

[0004] In the loading and packaging of finished goods, robotic arms are used in some applications to automate the loading process and improve automation. However, when using robotic arms to transfer and load goods onto pallets, the arm's gripping principle requires direct contact with and grasp of the goods' outer surface for stable transport. This process can easily cause scratches, indentations, and abrasions to the goods' surface, damaging not only the goods' appearance but also their protective layer or markings. Furthermore, damage to the outer surface can interfere with the adhesion and sealing of subsequent stretch film packaging, leading to uneven film coverage, loose packaging, gaps, and ultimately affecting the overall packaging quality and the protective effect of the goods during subsequent warehousing and transportation. Utility Model Content

[0005] The purpose of this invention is to solve the problem that when a robotic arm grasps the outer surface of a cargo for transfer and loading, it causes adverse effects on the outer surface of the cargo and affects subsequent packaging operations. Therefore, an automatic stretch film feeding and packaging device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic feeding and packaging device for stretch film, comprising a rotary feeding assembly, a packaging film mounting assembly, an automatic loading and unloading assembly, and a control terminal. The signal output terminal of the control terminal is interconnected with the signal input terminals of the rotary feeding assembly and the automatic loading and unloading assembly. The rotary feeding assembly includes a rotary component, a conveyor frame, a guide groove, and a traction device. The drive end of the rotary component is fixedly connected to the bottom end of the conveyor frame. The guide groove is fixedly installed in the middle of the conveyor frame, and the traction device is slidably connected inside the guide groove.

[0007] Preferably, the automatic loading and unloading assembly includes a support frame, an electrically controlled telescopic rod, and an adsorption end. The electrically controlled telescopic rod is fixedly installed on the top of the support frame, and the adsorption end is fixedly installed on the drive end of the electrically controlled telescopic rod. One end of the adsorption end is fixedly connected to a No. 3 magnet.

[0008] Preferably, the traction device includes a sliding frame, a chassis suction unit, and an adapter. The chassis suction unit is fixedly installed at one end of the sliding frame, and the adapter is fixedly installed at the other end of the sliding frame. The suction end is magnetically connected to the adapter.

[0009] Preferably, a slide rail is fixedly connected inside the guide groove, the sliding frame is slidably connected to the outside of the slide rail, and a stop block is symmetrically fixedly connected to the inner side of one end of the guide groove.

[0010] Preferably, the rotating assembly includes a drive motor, a drive gear, a transmission gear, and a rotating platform. The drive end of the drive motor is fixedly connected to the center of the drive gear. The drive gear and the transmission gear mesh with each other. The transmission gear is rotatably connected to the top surface of the rotating platform, and the other side of the transmission gear is fixedly connected to the bottom surface of the conveyor frame.

[0011] Preferably, a first magnet is fixedly installed in the middle of the chassis adsorber, and a second magnet is fixedly connected inside the adapter.

[0012] Preferably, the packaging film mounting assembly includes a mounting frame and a packaging film positioning rod, wherein the packaging film positioning rod is fixedly installed inside the mounting frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the automatic loading and unloading component and the traction device work together to achieve the loading and unloading of goods without the need for a robotic arm to clamp the goods, which can effectively protect the outer surface of the goods. The chassis adsorption method eliminates the need to repeatedly adjust the clamping parameters. With the electric control telescopic rod drive of the automatic loading and unloading component, the continuous action of "adsorption-traction-positioning" can be realized, reducing equipment waiting time and significantly improving the overall operating efficiency of the packaging production line.

[0014] 2. In this utility model, by fixing the guide groove to the middle position of the conveyor frame, the traction device slidably connected inside the guide groove can stably achieve the adsorption and traction operation of the pallet. This design avoids direct contact between the traction device and the outer surface of the goods, thus preventing any squeezing effect on the outer surface of the goods and further ensuring the integrity of the outer surface of the goods.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: As Figure 1 - Figure 4As shown, this utility model provides an automatic feeding and packaging device for stretch film, including a rotary feeding assembly 1, a packaging film mounting assembly 2, an automatic loading and unloading assembly 3, and a control terminal 4. The signal output terminal of the control terminal 4 is interconnected with the signal input terminals of the rotary feeding assembly 1 and the automatic loading and unloading assembly 3. The rotary feeding assembly 1 includes a rotary component 11, a conveyor frame 12, a guide groove 13, and a traction device 14. The driving end of the rotary component 11 is fixedly connected to the bottom end of the conveyor frame 12. The guide groove 13 is fixedly installed in the middle of the conveyor frame 12, and the traction device 14 is slidably connected inside the guide groove 13. The automatic loading and unloading assembly 3 includes a support frame 31, an electrically controlled telescopic rod 32, and an adsorption end 33. The electrically controlled telescopic rod 32 is fixedly installed at the top of the support frame 31, and the adsorption end 33 is fixedly installed at the driving end of the electrically controlled telescopic rod 32. A No. 3 magnet is fixedly connected to one end of the adsorption end 33. The rotary component 11 includes a drive motor 111, a drive gear 112, a transmission gear 113, and a rotating table 114. The drive end of machine 111 is fixedly connected to the center of drive gear 112. Drive gear 112 meshes with transmission gear 113. Transmission gear 113 is rotatably connected to the top surface of rotating table 114. The other side of transmission gear 113 is fixedly connected to the bottom surface of conveyor frame 12. Packaging film mounting assembly 2 includes mounting frame 21 and packaging film positioning rod 22. Packaging film positioning rod 22 is fixedly installed inside mounting frame 21. Traction device 14 includes sliding frame 141, chassis suction device 142 and adapter 14. 3. The chassis suction device 142 is fixedly installed at one end of the sliding frame 141, and the adapter 143 is fixedly installed at the other end of the sliding frame 141. The suction end 33 is magnetically connected to the adapter 143. The guide groove 13 is fixedly connected to the slide rail 131. The sliding frame 141 is slidably connected to the outside of the slide rail 131. The inner side of one end of the guide groove 13 is symmetrically fixedly connected to the stop block 132. A first magnet is fixedly installed in the middle of the chassis suction device 142, and a second magnet is fixedly connected inside the adapter 143.

[0020] The specific setup and function of this embodiment are described below. After the conveying equipment transports the goods to be packaged and their transfer pallets to one end of the conveyor frame 12, the chassis suction unit 142 at one end of the traction unit 14 performs a suction operation on the goods transfer pallet. The highest point of the chassis suction unit 142 is kept at the same horizontal level as the highest point of the rollers of the conveyor frame 12, ensuring that it does not interfere with the pallet transport process of the conveyor frame 12. Subsequently, the control terminal 4 drives the electrically controlled telescopic rod 32 to perform a reset action. The suction end 33 at its driving end drives the traction unit 14 to slide inside the guide groove 13, and the traction unit 14 then transports the goods and their pallets to the center position of the conveyor frame 12. At this time, the driving end of the electrically controlled telescopic rod 32 drives the suction end 33 to move to one end of the guide groove 13, and the stop block 132 abuts against the end of the sliding frame 141, effectively preventing the sliding frame 141 from sliding out of the guide groove 13; simultaneously, the adapter 143 and the suction end 33 are demagnetized under the action of the stop block 132, and the automatic loading operation is thus completed. The process achieves cargo loading and unloading through the coordinated operation of the automatic loading and unloading component 3 and the traction device 14, without the need for a robotic arm to clamp and load the cargo, thus effectively protecting the outer surface of the cargo. After automatic feeding is completed, one end of the packaging film is fixedly adhered to the outside of the goods. The control terminal 4 sends a command to the rotating assembly 11, which controls the drive motor 111 in the rotating assembly 11 to start and drive the drive gear 112 to rotate. Under the transmission action of the transmission gear 113, the conveyor frame 12 rotates accordingly, so that the packaging film is evenly wrapped around the outside of the goods, and the packaging operation is completed. After packaging is completed, the packaged goods are removed, and the rotating component 11 drives the conveyor frame 12 to return to its initial position. At the same time, the electrically controlled telescopic rod 32 drives the adsorption end 33 to extend into the guide groove 13. The adsorption end 33 and the adapter 143 re-establish a magnetic adsorption relationship, and push the sliding frame 141 to move to the other end of the guide groove 13. The entire equipment completes the reset operation and is ready for the next packaging operation.

[0021] Example 2: Figure 1 - Figure 4As shown, the automatic feeding and packaging equipment for stretch film of this utility model includes a rotary feeding assembly 1, a packaging film mounting assembly 2, an automatic loading and unloading assembly 3, and a control terminal 4. The signal output terminal of the control terminal 4 is interconnected with the signal input terminals of the rotary feeding assembly 1 and the automatic loading and unloading assembly 3. The rotary feeding assembly 1 includes a rotary component 11, a conveyor frame 12, a guide groove 13, and a traction device 14. The drive end of the rotary component 11 is fixedly connected to the bottom end of the conveyor frame 12. The guide groove 13 is fixedly installed in the middle of the conveyor frame 12. The traction device 14 is slidably connected inside the guide groove 13. The automatic loading and unloading assembly 3 includes a support frame 31, an electrically controlled telescopic rod 32, and an adsorption end 33. The electrically controlled telescopic rod 32 is fixedly installed on the support frame 31. At the top of 1, the adsorption end 33 is fixedly installed on the drive end of the electrically controlled telescopic rod 32. One end of the adsorption end 33 is fixedly connected to a No. 3 magnet. The traction device 14 includes a sliding frame 141, a chassis adsorber 142 and an adapter 143. The chassis adsorber 142 is fixedly installed on one end of the sliding frame 141 and the adapter 143 is fixedly installed on the other end of the sliding frame 141. The adsorption end 33 and the adapter 143 are magnetically connected. The guide groove 13 is fixedly connected to a slide rail 131. The sliding frame 141 is slidably connected to the outside of the slide rail 131. A stop block 132 is symmetrically fixedly connected to the inner side of one end of the guide groove 13. A No. 1 magnet is fixedly installed in the middle of the chassis adsorber 142 and a No. 2 magnet is fixedly connected inside the adapter 143.

[0022] The overall effect of this embodiment is that by fixing the guide groove 13 to the middle position of the conveyor frame 12, the traction device 14, which is slidably connected inside the guide groove 13, can stably achieve the adsorption and traction operation of the pallet. This design avoids direct contact between the traction device 14 and the outer surface of the goods, thus preventing any squeezing effect on the outer surface of the goods and further ensuring the integrity of the outer surface of the goods. Meanwhile, a detachable connection structure between the traction device 14 and the adsorption end 33 is constructed using magnetic force, which provides significant operational adaptability. When the rotating component 11 performs a rotational action, because the traction device 14 and the adsorption end 33 have achieved structural independence through magnetic separation, the electrically controlled telescopic rod 32 can remain in a relatively fixed state and will not interfere with the rotational movement of the rotating component 11. This ensures that the rotating component 11 can smoothly complete the self-rotation operation required for packaging and guarantees the overall stability and coordination of the equipment operation.

[0023] The operating method and working principle of this device are as follows: After the conveying equipment transports the goods to be packaged and their transfer pallets to one end of the conveyor frame 12, the chassis suction unit 142 at one end of the traction unit 14 performs suction operation on the goods transfer pallets. The highest point of the chassis suction unit 142 is kept at the same horizontal level as the highest point of the rollers of the conveyor frame 12, ensuring that it does not interfere with the pallet conveying process of the conveyor frame 12. Subsequently, the control terminal 4 drives the electrically controlled telescopic rod 32 to perform a reset action. The suction end 33 at its driving end drives the traction unit 14 to slide inside the guide groove 13, and the traction unit 14 then transports the goods and their pallets to the center position of the conveyor frame 12. At this time, the driving end of the electrically controlled telescopic rod 32 drives the suction end 33 to move to one end of the guide groove 13, and the stop block 132 abuts against the end of the sliding frame 141, effectively preventing the sliding frame 141 from sliding out of the guide groove 13; simultaneously, the adapter 143 and the suction end 33 are demagnetized under the action of the stop block 132, and the automatic loading operation is thus completed.

[0024] After automatic feeding is completed, one end of the packaging film is fixedly adhered to the outside of the goods. The control terminal 4 sends a command to the rotating assembly 11, which controls the drive motor 111 in the rotating assembly 11 to start and drive the drive gear 112 to rotate. Under the transmission action of the transmission gear 113, the conveyor frame 12 rotates accordingly, so that the packaging film is evenly wrapped around the outside of the goods, and the packaging operation is completed. After packaging is completed, the packaged goods are removed, and the rotating component 11 drives the conveyor frame 12 to return to its initial position. At the same time, the electrically controlled telescopic rod 32 drives the adsorption end 33 to extend into the guide groove 13. The adsorption end 33 and the adapter 143 re-establish a magnetic adsorption relationship, and push the sliding frame 141 to move to the other end of the guide groove 13. The entire equipment completes the reset operation and is ready for the next packaging operation.
