Description
Technical Field
[0001] This utility model relates to the field of stretch film support technology, and in particular to a stretch film support. Background Technology
[0002] Let me explain in detail what the main body is composed of. These components are essential for the normal and smooth operation of the main body. For example, a crusher consists of a casing, motor, conveyor belt, crushing rollers, and protective cover. The main body of a stretch film support consists of a base, support frame, connecting rods, etc.
[0003] Existing technologies, such as the utility model disclosed in the public account CN215325942U, specifically disclose a stretch film support bracket, including a base plate. A fixed universal wheel is welded to the bottom right side of the base plate, and a main support rod is slidably connected to the top of the base plate. A secondary support rod is riveted to the left side of the main support rod, and a first ring is riveted to the bottom of the secondary support rod. This stretch film support bracket allows for easy wrapping with a single hand by rotating the control panel, eliminating the need to bend over. This frees up labor and is convenient and practical, suitable for women, children, and the elderly. When the horizontal plate moves upward, the support force of the two universal wheels on the base plate increases, preventing the device from tipping over due to instability during lifting. After the stretch film is used up, pressing down on the right side of the arc-shaped rod allows for replacement with new stretch film, achieving convenient and time-saving replacement without the need to loosen or tighten nuts.
[0004] The following defects were found in the above-mentioned content: When using a traditional stretch film support to wrap the film, the film is uneven due to the different sizes of each film and the wrinkles of the film. Furthermore, the film is not easy to cut after it is wrapped. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where, when using traditional film wrapping supports to wrap films, the different sizes of each film and the wrinkles in the film result in uneven wrapping and make the film difficult to cut after wrapping. Therefore, this invention proposes a film wrapping support.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wrapping film support, comprising a base, a support fixedly connected to the upper surface of the base, a fixed rod movably connected inside the support, a film slidably connected to the arc surface of the fixed rod, a pressing device provided on the upper surface of the base, the pressing device comprising two fixing blocks, the interior of the two fixing blocks being slidably connected to the fixed rod, a pin being threadedly connected inside the fixing blocks, and one end of the pin being engaged with the fixed rod.
[0007] The effect achieved by the above components is to fix the membrane in place when the membrane size is different, thereby achieving the effect of pressing the membrane tightly during winding.
[0008] Preferably, two telescopic rods are fixedly connected to the upper surface of the support, and a carrying plate is fixedly connected to the upper surface of the two telescopic rods. The upper surface of the carrying plate is slidably connected to the membrane. A first spring is sleeved on the arc surface of the two telescopic rods, and the two ends of the first spring are fixedly connected to the support and the carrying plate, respectively.
[0009] The effect achieved by the above components is to further compress the membrane by relying on the elastic force of the first spring, so that the membrane is flat.
[0010] Preferably, a support column is fixedly connected to the upper surface of the base, a platform is fixedly connected to the upper surface of the support column, two columns are slidably connected to both ends of the platform, a pressure block is slidably connected to one end of the two columns that are close to each other, and the lower surface of the pressure block is slidably connected to the membrane.
[0011] The effect achieved by the above-mentioned components is that when the film is wrapped, the film is placed under the pressure block, and the weight of the pressure block can be used to press the film tightly during the wrapping process.
[0012] Preferably, the column is internally connected with a movable pin, and the end of the movable pin near the column is threadedly connected to the pressure block.
[0013] The effect achieved by the above-mentioned components is that, during the winding of the film, the height of the pressure block can be adjusted to further compress the film, making the film flatter during winding.
[0014] Preferably, an anti-slip pad is fixedly connected inside the column, and one end of the anti-slip pad is slidably connected to the pressure block.
[0015] The effect achieved by the above components is to make the pressure block smoother when adjusting its position.
[0016] Preferably, the upper surface of the base is provided with a shearing device, which includes two support blocks. A connecting rod is fixedly connected to one end of the two support blocks that are close to each other. A moving block is slidably connected to the arc surface of the connecting rod. A connecting block is fixedly connected to the upper surface of the moving block. A torsion block is rotatably connected inside the connecting block. A blade is fixedly connected to one end of the torsion block. A screw is threaded inside the connecting block. The end of the screw near the torsion block is engaged with the blade.
[0017] The aforementioned components achieve the following effect: when the film wrapping is completed, the moving block can be moved to drive the blade to move, thus cutting the film, and when not in use, the blade can be rotated to retract the blade.
[0018] Preferably, a second spring is fitted onto the arc surface of the connecting rod, and the two ends of the second spring are fixedly connected to the support block and the moving block, respectively.
[0019] The effect achieved by the above components is that the blade is positioned to one side by the elastic force of the second spring when the shearing device is not in use.
[0020] In summary, the beneficial effects of this utility model are as follows:
[0021] In this invention, when wrapping the film, first remove the fixing rod, then remove the pins on the fixing block, then remove the fixing block, and then put the film on the fixing rod. Move the film to the appropriate position, then put the removed fixing block on the fixing rod from both ends of the film, pressing it tightly against the film, and then insert the pins to fix the fixing block, thus securing the film. Then press down the carrier plate and insert the fixing rod into the bracket. Under the elastic force of the first spring on the telescopic rod, the carrier plate is moved to press tightly against the film. Remove the two movable pins on the column, move the pressure block upward, then pass the film under the pressure block, and then move the pressure block downward to make the pressure block press tightly against the film. Insert the movable pins. In this way, the film is flattened by the action of the pressure block and the carrier plate, thus wrapping the film. The anti-slip pad prevents the pressure block from slipping when moving, further tightening the film.
[0022] In this invention, when the film needs to be cut, first pull out the toggle block inserted on the connecting block, rotate the blade until the tip faces the film, then insert the toggle block again, and then pull out the piston inserted on the moving block to push the blade handle towards the compression spring. Thus, the film is cut under the action of the blade. After cutting the film, release the blade handle, so that the blade is positioned to one side under the elastic force of the second spring, not affecting the next film winding. Then insert the piston on the moving block to keep the blade on one side. Then pull out the toggle block inserted on the connecting block, rotate the blade until the tip faces the ground, and then insert the toggle block again. This prevents the blade from injuring people when not in use. Attached Figure Description

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a wrapping film support, including a base 1, a support 2 fixedly connected to the upper surface of the base 1, a fixing rod 3 movably connected inside the support 2, a film 4 slidably connected to the arc surface of the fixing rod 3, a pressing device 5 provided on the upper surface of the base 1, and a shearing device 6 provided on the upper surface of the base 1.
[0029] The specific setup and function of the clamping device 5 and the shearing device 6 will be explained in detail below.
[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the pressing device 5 includes two fixing blocks (510), the interior of the two fixing blocks 510 is slidably connected to the fixing rod 3, and the interior of the fixing blocks 510 is threaded with a pin 511. One end of the pin 511 is engaged with the fixing rod 3, which can fix the film 4 to prevent it from moving when the film 4 is of different sizes, thus achieving the effect of pressing the film 4 when it is wrapped. Two telescopic rods 507 are fixedly connected to the upper surface of the support 2, and a carrying plate 509 is fixedly connected to the upper surface of the two telescopic rods 507. The upper surface of the carrying plate 509 is slidably connected to the film 4. The arc surface of the two telescopic rods 507 is fitted with a first spring 508. The two ends of the first spring 508 are fixedly connected to the support 2 and the carrying plate 509 respectively. The elastic force of the first spring 508 further presses the film 4, making the film 4 flat. A support column 505 is fixedly connected to the upper surface of the base 1. A platform 506 is fixedly connected to the upper surface of the support column 505. Two uprights 501 are slidably connected to both ends of the platform 506. A pressure block 502 is slidably connected to the end of the two uprights 501 that is close to each other. The lower surface of the pressure block 502 is slidably connected to the film 4. When wrapping the film 4, the film 4 is placed under the pressure block 502, and the weight of the pressure block 502 can achieve the effect of pressing the film 4 tightly during wrapping. A movable pin 503 is movably connected inside the upright 501. The end of the movable pin 503 near the upright 501 is threadedly connected to the pressure block 502. When wrapping the film 4, the height of the pressure block 502 can be adjusted, thereby further pressing the film 4 and making the film 4 flatter during wrapping. An anti-slip pad 504 is fixedly connected inside the upright 501. One end of the anti-slip pad 504 is slidably connected to the pressure block 502, making the pressure block 502 smoother when adjusting its position.
[0031] Reference Figure 4 As shown in this embodiment: the shearing device 6 includes two support blocks 61. A connecting rod 62 is fixedly connected to one end of each support block 61 that is close to the other. A movable block 64 is slidably connected to the arc surface of the connecting rod 62. A connecting block 66 is fixedly connected to the upper surface of the movable block 64. A torsion block 67 is rotatably connected inside the connecting block 66. A blade 68 is fixedly connected to one end of the torsion block 67. A screw 69 is threaded inside the connecting block 66. The end of the screw 69 near the torsion block 67 engages with the blade 68. When the wrapping film 4 is completed, the movable block 64 can be moved to move the blade 68, allowing the blade 68 to cut the film 4. When not in use, the blade 68 can be rotated to retract. A second spring 63 is fitted onto the arc surface of the connecting rod 62. The two ends of the second spring 63 are fixedly connected to the support block 61 and the movable block 64, respectively. When the shearing device 6 is not in use, the elastic force of the second spring 63 keeps the blade 68 to one side.
[0032] Working principle: In this utility model, when wrapping the film 4, first remove the fixing rod 3, then remove the pin 511 on the fixing block 510, then remove the fixing block 510, then put the film 4 on the fixing rod 3, move the film 4 to a suitable position, then put the removed fixing block 510 on the fixing rod 3 from both ends of the film 4, close to the film 4, then insert the pin 511 to fix the fixing block 510, thus fixing the film 4. Then press the carrier plate 509 and insert the fixing rod 3 into the bracket 2. In this way, under the action of the elastic force of the first spring 508 on the telescopic rod 507, the carrier plate 509 is driven to closely adhere to the film 4. Remove the two movable pins 503 on the column 501, move the pressure block 502 upwards, then pass the membrane 4 under the pressure block 502, and then move the pressure block 502 downwards to make the pressure block 502 press firmly against the membrane 4. Insert the movable pins 503. In this way, the membrane 4 is made flat by the action of the pressure block 502 and the platform 506, thus wrapping the membrane 4. The anti-slip pad 504 serves to prevent the pressure block 502 from slipping when it moves, further pressing the membrane 4.
[0033] In this invention, when it is necessary to cut the membrane 4, first pull out the toggle block 67 inserted on the connecting block 66, rotate the blade 68 until the tip of the blade 68 faces the membrane 4, then insert the toggle block 67, and then pull out the piston 65 inserted on the moving block 64 to push the blade 68 handle towards the compression spring. In this way, the membrane 4 is cut under the action of the blade 68, thus achieving the cutting effect. After cutting the membrane 4, release the blade 68 handle. Under the elastic force of the second spring 63, the blade 68 is positioned to one side, which does not affect the next winding of the membrane 4. Then insert the piston 65 on the moving block 64 to keep the blade 68 on one side. Then pull out the toggle block 67 inserted on the connecting block 66, rotate the blade 68 until the tip of the blade 68 faces the ground, and then insert the toggle block 67 again. This is to prevent the blade 68 from injuring people when it is not in use.
