Description

Technical Field

[0001] This utility model relates to the field of top-covering film machine technology, specifically a through-type top-covering film outlet mechanism. Background Technology

[0002] Vertical wrapping machines typically wrap around the four sides of goods, while many products require top wrapping machines to cover the top, thus completing the wrapping and packaging of all five sides of the product. Through-type wrapping is mainly for online unmanned packaging situations. This machine works in conjunction with the wrapping machine, with items passing through the conveyor line to achieve automatic top wrapping and packaging, and automatic transport to the next packaging station.

[0003] In the Chinese patented photovoltaic aluminum frame automatic packaging system through-type top film covering machine (patent number: CN119117345A), the device includes a film dispensing mechanism, a cutting mechanism, a measuring mechanism, and a pulling mechanism. The film dispensing mechanism includes two base frames, a guide frame connected between the two base frames, a feeding box slidably installed inside the guide frame, a threaded rod vertically penetrating the feeding box, and a motor connected between the guide frame and the threaded rod. In this device, after the goods arrive between two bidirectional electric push rods, the external PLC, under the supervision of the operator, starts the bidirectional electric push rods. The movable end of the bidirectional electric push rods extends or retracts, and then the distance between the two adjustable outer plates changes. When the distance between the two adjustable outer plates is greater than the top area of ​​the goods, the cylinder is activated, and then the cutter cuts the film, which is then spread and laid on top of the goods. The amount of film used is precisely controlled to avoid waste. However, because the device does not have a positioning mechanism for the end of the top film, the end of the top film will deviate after each cut, making it difficult for the electric clamp to hold it accurately, thus affecting work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a through-type overlay membrane delivery mechanism to solve the problems mentioned in the background art.

[0006] As a further embodiment of this utility model: the synchronous drive mechanism includes a cover fixed to the outer wall of the first fixed plate, a synchronous motor fixedly connected to the outer wall of the cover, a first rotating rod fixedly connected to the main shaft end of the synchronous motor, the first rotating rod passing through the first fixed plate and fixedly connected to the rotating roller, a second rotating rod inserted into and rotatably connected to the side wall of the first fixed plate, one end of the second rotating rod fixedly connected to the lower clamping roller, a driving wheel fixedly connected to the first rotating rod, a driven wheel fixedly connected to the second rotating rod, and the driving wheel being connected to the driven wheel via a transmission belt.

[0007] As a further embodiment of this utility model: the clamping mechanism includes a fixed shell fixed to the side wall of the first fixed plate, a vertical rod fixedly connected in the fixed shell, a sliding sleeve sleeved on the vertical rod, a clamping spring fixedly connected between the sliding sleeve and the inner top wall of the fixed shell, a rotating shaft rotatably connected to one side of the sliding sleeve, and one end of the rotating shaft rotatably connected to the upper clamping roller.

[0008] As a further embodiment of this utility model: the cutting mechanism includes a support frame fixed to the upper side wall of the concave guide frame, a first push rod fixedly connected to the middle of the upper side wall of the support frame, and the lower end of the first push rod passing through the support frame and fixedly connected to a cutting blade.

[0009] As a further embodiment of this utility model: the translation mechanism includes a stepper motor fixed to the radial end of the concave guide frame, the main shaft end of the stepper motor passing through the concave guide frame and fixedly connected to a lead screw, a nut block threaded onto the lead screw, a connecting rod fixedly connected to one side of the nut block, and one end of the connecting rod fixedly connected to the moving frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This through-type covered film delivery mechanism, through the configuration of a synchronous drive mechanism, a rotating roller, a lower clamping roller, an upper clamping roller, and a pressing mechanism, mounts the covered film roll onto the rotating roller. Then, the upper clamping roller moves upward, causing the sliding sleeve to shift on the vertical rod. At this time, the pressing spring is compressed and contracts, generating elastic force that inserts the end of the covered film into the lower clamping roller. Releasing the upper clamping roller, the elastic force of the pressing spring pushes the upper clamping roller downward, automatically pressing the end of the covered film against the lower clamping roller. This allows for the precise handling of the covered film end. The positioning of the top film end is used to prevent it from deviating, so that the subsequent clamping mechanism can accurately clamp the top film end, thus facilitating film output. Then, the synchronous motor is started to drive the rotating roller fixed to the first rotating rod to rotate, which can realize the automatic unwinding of the top film roll. At the same time, since the driving wheel is driven by the driven wheel through the transmission belt, it can drive the lower clamping roller fixed to the second rotating rod to rotate, realizing the automatic output and conveying of the top film roll end clamped between the lower clamping roller and the upper clamping roller, making the output of the top film more stable.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] Please see Figures 1-4 In this practical embodiment, a through-type top-covering film delivery mechanism is provided. This device can be used in conjunction with the lifting mechanism of the top-covering film machine to control the height of the device according to the top height of the packaged goods. The lifting mechanism is existing technology of the top-covering film machine, so it will not be explained in detail here. It includes a concave guide frame 1. The rear ends of the concave guide frame 1 are respectively fixedly connected to a first fixed plate 2 and a second fixed plate 3. The outer side wall of the first fixed plate 2 is fixedly connected to a synchronous drive mechanism. The first end of the synchronous drive mechanism passes through the first fixed plate 2 and is fixedly connected to a rotating roller 4. The second end of the synchronous drive mechanism passes through the first fixed plate 2 and is fixedly connected to a lower clamping roller 5. Both the first fixed plate 2 and the second fixed plate 3 are fixedly connected to a pressing mechanism. An upper clamping roller 6 is rotatably connected between the two pressing mechanisms. The upper clamping roller 6 and the lower clamping roller 5 are pressed together. A cutting mechanism is fixedly connected to the upper side wall of the transverse section of the concave guide frame 1. Both radial sections of the concave guide frame 1 are provided with translation mechanisms. A moving frame 7 is fixedly connected between the two translation mechanisms. Two symmetrically arranged clamping mechanisms are fixedly connected to the moving frame 7.

[0021] like Figure 2 and Figure 3As shown: The synchronous drive mechanism includes a housing 8 fixed to the outer wall of the first fixed plate 2. A synchronous motor 9 is fixedly connected to the outer wall of the housing 8. A first rotating rod 10 is fixedly connected to the main shaft end of the synchronous motor 9. The first rotating rod 10 passes through the first fixed plate 2 and is fixedly connected to the rotating roller 4. A second rotating rod 11 is inserted into and rotatably connected to the side wall of the first fixed plate 2. One end of the second rotating rod 11 is fixedly connected to the lower clamping roller 5. A drive wheel 12 is fixedly connected to the first rotating rod 10, and a drive wheel 12 is fixedly connected to the second rotating rod 11. A driven wheel 13 is connected to the driven wheel 12 via a transmission belt 14. When the synchronous motor 9 is working, it drives the rotating roller 4, which is fixed to the first rotating rod 10, to rotate, thereby realizing the automatic unwinding of the top-coated film roll. At the same time, since the driven wheel 12 is driven by the driven wheel 13 via the transmission belt 14, it can drive the lower clamping roller 5, which is fixed to the second rotating rod 11, to rotate, thereby realizing the automatic film delivery of the top-coated film roll held between the lower clamping roller 5 and the upper clamping roller 6, making the film delivery of the top-coated film more stable.

[0022] like Figure 3 As shown: The clamping mechanism includes a fixed shell 15 fixed to the upper side wall of the first fixed plate 2. A vertical rod 16 is fixedly connected to the fixed shell 15. A sliding sleeve 17 is sleeved on the vertical rod 16. A clamping spring 18 is fixedly connected between the sliding sleeve 17 and the inner top wall of the fixed shell 15. A rotating shaft 19 is rotatably connected to one side of the sliding sleeve 17. One end of the rotating shaft 19 is rotatably connected to the upper clamping roller 6. When the upper clamping roller 6 is moved upward, the sliding sleeve 17 is displaced on the vertical rod 16. At this time, the clamping spring 18 is compressed and contracts to generate elastic force, inserting the end of the top film into the lower clamping roller 5. When the upper clamping roller 6 is released, the elastic force of the clamping spring 18 pushes the upper clamping roller 6 to automatically press down and clamp the end of the top film between it and the lower clamping roller 5. This can achieve the positioning of the end of the top film and prevent the end of the top film from deviating, so that the subsequent clamping mechanism can accurately clamp the end of the top film, thereby facilitating film discharge.

[0023] like Figure 1 As shown: The cutting mechanism includes a support frame 20 fixed to the upper side wall of the concave guide frame 1. A first push rod 21 is fixedly connected to the middle of the upper side wall of the support frame 20. The lower end of the first push rod 21 passes through the support frame 20 and is fixedly connected to a cutting blade 22. When the top film extends to a suitable length, the top film covers the packaging. The first push rod 21 is activated to extend, pushing the cutting blade 22 down to cut the top film.

[0024] like Figure 4As shown: The translation mechanism includes a stepper motor 23 fixed to the radial end of the concave guide frame 1. The main shaft of the stepper motor 23 passes through the concave guide frame 1 and is fixedly connected to a lead screw 24. A nut block 25 is threaded onto the lead screw 24. A connecting rod 26 is fixedly connected to one side of the nut block 25. One end of the connecting rod 26 is fixedly connected to the moving frame 7. When the clamping mechanism clamps the end of the top film, the stepper motor 23 is started to work, driving the lead screw 24 to rotate. Since the lead screw 24 is threadedly connected to the nut block 25, the nut block 25 is forced to translate, which can drive the moving frame 7 fixed to the connecting rod 26 to move, thereby driving the two clamping mechanisms to clamp the end of the top film and pull it out, realizing the film removal operation.

[0025] like Figure 4 As shown: The clamping mechanism includes a lower clamping plate 27 fixed to the upper side wall of the movable frame 7. An L-shaped frame 28 is fixedly connected to the upper rear end of the lower clamping plate 27. A second push rod 29 is fixedly connected to the upper side wall of the L-shaped frame 28. The lower end of the second push rod 29 passes through the L-shaped frame 28 and is fixedly connected to an upper clamping plate 30. When the end of the covering film is placed between the lower clamping plate 27 and the upper clamping plate 30, the second push rod 29 is activated to extend, pushing the upper clamping plate 30 downward, so that the lower clamping plate 27 and the upper clamping plate 30 clamp and fix the end of the covering film, so that the covering film can be pulled out later.

[0026] It is worth noting that the electrical components such as the synchronous motor 9, the first push rod 21, the stepper motor 23, and the second push rod 29 in this utility model are all controlled by the control system of the top film covering machine.

[0027] Working Principle: When using this device for the top-coated film unloading operation, firstly, the top-coated film roll is installed on the rotating roller 4. Then, the upper clamping roller 6 is moved upward, causing the sliding sleeve 17 to move on the vertical rod 16. At this time, the clamping spring 18 is compressed and contracts, generating elastic force to insert the end of the top-coated film into the lower clamping roller 5. The upper clamping roller 6 is then released. Using the elastic force of the clamping spring 18, the upper clamping roller 6 is automatically pushed downward, pressing the end of the top-coated film against the lower clamping roller 5. This achieves positioning of the top-coated film end and prevents overloading. The top film end deviates so that the subsequent clamping mechanism can accurately clamp the top film end, thus facilitating film output. Then, the synchronous motor 9 is started to drive the rotating roller 4 fixed to the first rotating rod 10 to rotate, which can realize the automatic unwinding of the top film roll. At the same time, since the driving wheel 12 is driven by the driven wheel 13 through the transmission belt 14, it can drive the lower clamping roller 5 fixed to the second rotating rod 11 to rotate, realizing the automatic film output and conveying of the top film roll end clamped between the lower clamping roller 5 and the upper clamping roller 6, making the top film output more stable.

[0028] Then, when the end of the covering film is placed between the lower clamping plate 27 and the upper clamping plate 30, the second push rod 29 is activated to extend, pushing the upper clamping plate 30 downward, so that the lower clamping plate 27 and the upper clamping plate 30 clamp and fix the end of the covering film, so that the covering film can be pulled out later. After the clamping mechanism clamps the end of the covering film, the stepper motor 23 is activated to drive the lead screw 24 to rotate. Since the lead screw 24 is threadedly connected to the nut block 25, the nut block 25 is forced to move, which can drive the moving frame 7 fixed to the connecting rod 26 to move, thereby driving the two clamping mechanisms to clamp the end of the covering film and pull it out, realizing the film output operation. When the covering film is output to a suitable length, the covering film is placed on the packaging, and the first push rod 21 is activated to extend, pushing the cutting blade 22 down to cut the covering film.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
