Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stretch film packaging machines, specifically a stretch film packaging machine. Background Technology
[0002] Stretch wrap film has excellent tensile properties, tear resistance, strong puncture resistance, high transparency, good self-adhesion, and high shrinkage rate. When packaging goods, it can wrap and pack them tightly to prevent damage during handling. Goods wrapped in stretch wrap film are more stable, aesthetically pleasing, and neat. In addition, it can play a role in waterproofing, dustproofing, preventing scattering, preventing theft, blocking light, and protecting against ultraviolet radiation during long-distance transportation or long-term storage.
[0003] When manually wrapping stretch film onto the outer surface of goods, workers need to hold the film in their hands and circle around the goods to wrap it around their surface. However, because the stretch film is heavy and workers need to circle around the goods, workers are very likely to get injured when packing the goods. In addition, the heavy stretch film and excessive movement will increase the labor intensity of workers, causing their work efficiency to gradually decrease. Utility Model Content
[0004] The purpose of this invention is to provide a wrapping machine to solve the problems mentioned in the background art, such as the gradual decline in worker efficiency and high labor intensity when wrapping goods.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stretch wrapping machine, comprising a universal wheel base, a control end fixedly mounted on the outer surface of the universal wheel base, and a column groove fixedly mounted on one side of the outer surface of the control end, a drive motor fixedly mounted inside the universal wheel base, the operating surface of the control end located on the side away from the universal wheel base, a bearing turntable assembly rotatably mounted on the outer surface of the end of the universal wheel base away from the control end, and a worm gear fixedly mounted on one end of the bearing turntable assembly inside the universal wheel base, a worm rotatably mounted inside the universal wheel base, and the worm gear connected to the drive motor, the worm gear meshing with the worm gear, and the worm gear and the bearing turntable assembly being concentrically designed.
[0006] Preferably, a rubber pad is attached to the outer surface of the bearing turntable assembly, and a square through hole is opened on the outer surface of the universal wheel base near the drive motor and the worm gear. A reinforcing liner is fixedly installed on the outer surface of the universal wheel base near the bearing turntable assembly, and the reinforcing liner and the bearing turntable assembly are concentrically designed.
[0007] By adopting the above technical solution, the rubber pad on the outer surface of the bearing turntable assembly can effectively prevent the goods from slipping when the bearing turntable assembly rotates. The square through hole on the outer surface of the universal wheel base allows for easy disassembly of the drive motor, worm gear, and worm wheel if they are damaged. The design of the reinforcing liner can improve the strength between the universal wheel base and the bearing turntable assembly, reduce the probability of deformation and damage to the universal wheel base, facilitate maintenance and repair, and extend the service life of the packing machine.
[0008] Preferably, a servo motor is fixedly installed on the outer surface of the column slide groove, and the output end of the servo motor passes through the outer surface of the column slide groove. A screw is rotatably installed inside the column slide groove and is connected to the output end of the servo motor. A slider is slidably installed inside the column slide groove, and a load-bearing block is rotatably installed at the end of the slider away from the column slide groove. The outer surface of the load-bearing block is in contact with the outer surface of the core of the wrapping film.
[0009] By adopting the above technical solution, the slider can move up and down inside the column groove to pack goods of different heights. The setting of the load-bearing block can reduce the jerking when the stretch film is fed, reduce the chance of the stretch film being torn, and allow the stretch film to rotate smoothly and move up and down. This facilitates the packing of goods of different specifications while reducing the labor intensity of workers.
[0010] Preferably, a through-fixing rod is fixedly installed on the outer surface of the slider, and the through-fixing rod and the load-bearing block are concentrically designed. The load-bearing block and the through-fixing rod are rotatably connected. A set screw sleeve is installed through the outer surface of the through-fixing rod, and a plug is slidably installed on the outer surface of the set screw sleeve. The outer surface of the plug is tapered and fits against the outer surface of the core of the wrapping film. The set screw sleeve and the through-fixing rod are slidably connected, and the through-fixing rod and the set screw sleeve are engaged.
[0011] By adopting the above technical solution, the inserting fixing rod can limit the position of the stretch film inserted on the outer surface of the slider. At the same time, with the use of screw sleeves and plugs, the up-and-down movement of the stretch film as the load-bearing block rotates is reduced, so that the stretch film can maintain a stable position during the packaging process, thereby ensuring the accuracy and consistency of the packaging.
[0012] Preferably, the outer surface of the set screw sleeve is threaded with two round nuts, and the outer surfaces of the round nuts fit together. A spring is provided between the round nuts and the plug.
[0013] By using the above technical solution, the spring force can be adjusted by locking and rotating the two round nuts, which allows the force of the plug pressing the stretch film to be adjusted, and the friction between the load-bearing block and the slider can be changed. This adjusts the tightness of the stretch film when it is being released, ensuring that the stretch film remains taut when it is wrapped around the surface of the goods, thus guaranteeing the quality of the goods packaged with the stretch film.
[0014] Preferably, a placement rack is fixedly installed on the outer surface of the omnidirectional wheel base near the control end, and the end of the placement rack near the control end is designed to be inclined, and the inside of the placement rack contains stacked wrapping film.
[0015] By adopting the above technical solution, the stretch film can be placed and stored through the placement rack, making it convenient to retrieve after use. At the same time, the universal wheel base can transport the stored stretch film, reducing the trouble of retrieving the stretch film back and forth and reducing the labor intensity when retrieving and moving the stretch film.
[0016] Preferably, telescopic hydraulic outriggers are slidably installed inside both ends of the universal wheel base, and the telescopic hydraulic outriggers are engaged with the universal wheel base. The length of the telescopic hydraulic outriggers does not exceed both ends of the universal wheel base.
[0017] By adopting the above technical solution, the universal wheel base is extended and activated by the telescopic hydraulic outriggers, which can slightly lift the universal wheel base, expand the lever arm supporting the universal wheel base, make the universal wheel base more stable, and prevent the universal wheel base from tipping over during the packaging process.
[0018] Compared with the prior art, the beneficial effects of this utility model are: This stretch film packaging machine:
[0019] 1. When packing, workers simply move the packing device to the desired location using the caster base, then place the goods on the bearing turntable assembly. The drive motor is then activated via the control terminal, causing it to rotate along with the worm gear. This allows the worm wheel, which meshes with the worm gear, to rotate as well, enabling the bearing turntable assembly and the goods to rotate simultaneously. The self-locking property of the worm gear and worm wheel prevents the bearing turntable assembly from automatically reversing after stopping, which could cause the packing film to loosen. This also reduces the rotation speed of the bearing turntable assembly, allowing workers to move the packing device to the packing location without having to run around the goods. This significantly reduces the labor intensity of workers and also reduces the rotation speed of the bearing turntable assembly. Furthermore, the bearing turntable assembly does not automatically reverse after stopping, preventing the stretch film from loosening.
[0020] 2. As the servo motor starts and drives the screw to rotate, the slider can move up and down in the column groove. The movement of the slider moves the stretch film to a position level with the height of the goods. Then the stretch film can be inserted into the goods for fixation. When the bearing turntable assembly rotates and drives the goods to rotate, the use of the load-bearing placement block will reduce the jamming when the stretch film rotates, allowing the stretch film to be continuously and smoothly fed without breaking due to uneven feeding. The goods can be completely wrapped as the slider descends, reducing the chance of stretch film breakage and ensuring that goods of different heights can be packaged.
[0021] 3. By using the insert fixing rod, the stretch film placed on the outer surface of the slider can be limited, preventing it from falling off as the load-bearing block rotates. Simultaneously, after inserting the set screw sleeve and plug into the outer surface of the insert fixing rod, the tapered design of the plug will press firmly against the stretch film, reducing its vertical movement after rotation and allowing for the fixing of stretch films of different widths. Furthermore, by rotating and locking the round nut, the spring force can be adjusted, allowing the spring to push the plug to apply pressure to the load-bearing block and stretch film, thereby changing the friction between the load-bearing block and the slider. This controls the tightness of the stretch film when packaging goods, ensuring it remains taut when wrapped around the goods, preventing it from loosening after packaging and guaranteeing the quality of the packaging.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-6 This utility model provides a technical solution: a stretch wrapping machine, including a universal wheel base 1, a control end 2 fixedly installed on the outer surface of the universal wheel base 1, and a column slide groove 3 fixedly installed on one side of the outer surface of the control end 2, a drive motor 16 fixedly installed inside the universal wheel base 1, the operating surface of the control end 2 located on the side away from the universal wheel base 1, a bearing turntable assembly 15 rotatably installed on the outer surface of the end of the universal wheel base 1 away from the control end 2, and a worm gear 18 fixedly installed at one end of the bearing turntable assembly 15 inside the universal wheel base 1, a worm 17 rotatably installed inside the universal wheel base 1, and the worm 17 is connected to the drive motor 16, the worm 17 meshes with the worm gear 18, and the worm gear 18 and the bearing turntable assembly 15 are concentrically designed.
[0031] The packaging device can be flexibly moved via the caster base 1, making it convenient to move to the desired location for packaging. The control terminal 2 controls the operation of the electrical components inside the packaging machine. When packaging goods, simply place the goods on the outer surface of the bearing turntable assembly 15, and then start the drive motor 16 via the control terminal 2 to rotate the worm gear 17. This allows the worm wheel 18, which meshes with the worm gear 17, to rotate as well, causing the bearing turntable assembly 15 to rotate together. The self-locking and speed-reducing properties of the worm gear 17 and the worm wheel 18 not only effectively prevent the bearing turntable assembly 15 from rotating in the opposite direction when it stops, but also reasonably reduce the rotational speed of the bearing turntable assembly 15. In this way, workers do not need to rotate around the goods, greatly reducing labor intensity, while ensuring that the bearing turntable assembly 15 has an appropriate speed during rotation and stability after stopping.
[0032] A rubber pad is attached to the outer surface of the bearing turntable assembly 15. A square through hole is opened on the outer surface of the universal wheel base 1 near the drive motor 16 and the worm gear 18. A reinforcing liner 14 is fixedly installed on the outer surface of the universal wheel base 1 near the bearing turntable assembly 15, and the reinforcing liner 14 and the bearing turntable assembly 15 are concentrically designed.
[0033] The rubber pads on the outer surface of the bearing turntable assembly 15 can effectively prevent slippage and falling of goods during packing. The square through holes on the outer surface of the universal wheel base 1 make it easy to replace and maintain the drive motor 16, worm gear 17, and worm wheel 18. At the same time, the use of the reinforcing liner 14 can effectively strengthen the strength between the bearing turntable assembly 15 and the universal wheel base 1, allowing the bearing turntable assembly 15 to hold heavier goods and reducing the chance of deformation and damage to the universal wheel base 1.
[0034] A servo motor 4 is fixedly installed on the outer surface of the column slide 3, and the output end of the servo motor 4 passes through the outer surface of the column slide 3. A screw 5 is rotatably installed inside the column slide 3, and the screw 5 is connected to the output end of the servo motor 4. A slider 6 is slidably installed inside the column slide 3, and a load-bearing block 7 is rotatably installed at the end of the slider 6 away from the column slide 3, and the outer surface of the load-bearing block 7 is in contact with the outer surface of the core of the wrapping film.
[0035] The rotation of the servo motor 4 drives the screw 5 to rotate as well, allowing the slider 6 connected to the screw 5 to move up and down inside the column groove 3. This causes the stretch film to move up and down, enabling the packaging of goods of different heights. At the same time, the use of the load-bearing block 7 makes the stretch film rotate more smoothly without any jerking, reducing the risk of breakage due to uneven rotation. The stretch film can move with the slider 6 to package goods of different heights while reducing the chance of breakage due to uneven rotation, improving the convenience and efficiency of packaging goods of different sizes, and eliminating the need for workers to handle the stretch film, thus reducing the labor intensity of workers.
[0036] A through-fixing rod 8 is fixedly installed on the outer surface of the slider 6, and the through-fixing rod 8 and the load-bearing block 7 are concentrically designed. The load-bearing block 7 and the through-fixing rod 8 are rotatably connected. A set screw sleeve 9 is installed through the outer surface of the through-fixing rod 8, and a plug 11 is slidably installed on the outer surface of the set screw sleeve 9. The outer surface of the plug 11 is tapered, and the plug 11 is in contact with the outer surface of the core of the wrapping film. The set screw sleeve 9 and the through-fixing rod 8 are slidably connected, and the through-fixing rod 8 and the set screw sleeve 9 are engaged.
[0037] The insertion and fixing rod 8 can limit the position of the stretch film placed on the outer surface of the slider 6. In addition, when used together with the set screw sleeve and the plug 11, it can effectively fix stretch film of different lengths and reduce the chance of the stretch film moving up and down during rotation. In this way, the stretch film can always maintain a stable position during the packaging of goods, thus ensuring the accuracy and consistency of the packaging work.
[0038] Two round nuts 12 are threaded on the outer surface of the set screw sleeve 9, and the outer surfaces of the round nuts 12 fit together. A spring 10 is provided between the round nuts 12 and the plug 11.
[0039] By rotating and locking the two round nuts 12 together, the elastic force of the spring 10 can be adjusted. The change in the elastic force of the spring 10 can also adjust the force of the plug 11 pressing the stretch film, thereby changing the friction between the load-bearing block 7 and the slider 6. In this way, the tightness of the stretch film when packaging goods can be controlled, ensuring that the stretch film remains taut when wrapped around the surface of the goods, thus ensuring the quality of the goods packaged with stretch film.
[0040] A placement rack 13 is fixedly installed on the outer surface of the omnidirectional wheel base 1 near the control end 2, and the placement rack 13 near the control end 2 is designed to be inclined. The inside of the placement rack 13 is filled with stacked wrapping film.
[0041] The placement rack 13 enables proper placement and storage of the stretch film. After the stretch film is used up, it can be taken out from the placement rack 13, making operation and use more convenient. At the same time, the presence of the caster wheel base 1 facilitates the transportation of the stored stretch film, effectively avoiding the tediousness of frequently taking out the stretch film and significantly reducing the labor intensity of workers in the process of taking out and moving the stretch film.
[0042] Telescopic hydraulic outriggers 19 are slidably installed inside both ends of the universal wheel base 1, and the telescopic hydraulic outriggers 19 are engaged with the universal wheel base 1. The length of the telescopic hydraulic outriggers 19 does not exceed both ends of the universal wheel base 1.
[0043] When the telescopic hydraulic outrigger 19 extends from the caster base 1 and is activated, it can slightly lift the caster base 1. This action effectively expands the lever arm supporting the caster base 1, thereby greatly enhancing the stability of the caster base 1 and ensuring that the caster base 1 will not tip over during the packing process, thus ensuring the smooth progress of the packing work.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
