Description

Technical Field

[0001] This utility model relates to the field of stacking device technology, and in particular to an anti-fog film stacking device. Background Technology

[0002] Anti-fog film, also known as drip-free film, is a film made by adding an anti-fog agent to the formula of polyvinyl chloride or polyethylene agricultural film. When ordinary agricultural film (fog-prone film) is used to cover seedlings, water vapor inside the greenhouse will continuously condense on the inner surface of the film due to the rise in soil temperature, generating a large number of fine water droplets and forming an opaque, fog-like white water film. This reduces the light transmittance and prevents the temperature inside the greenhouse from rising quickly.

[0003] Existing anti-fog films are rolled up in a cylindrical shape. The surface resistance of anti-fog films is high, and they are prone to static electricity due to friction. Most of the rolled-up anti-fog films are stacked horizontally or placed vertically on the shelves, which can easily cause the film rolls to adhere to each other. When taking them out, the outer layers of the film rolls can be pulled together, affecting the winding. At the same time, the vibration during transportation can cause the film rolls to hit the inner wall of the shelf, causing wear and tear on the film rolls. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-fog film stacking device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A defogging film stacking device includes a stacking frame, a tray frame, and a bidirectional lead screw assembly. A plurality of tray frames are arrayed inside the stacking frame. Each tray frame has a plurality of slots extending through its top. A protective pad is provided on the top of each tray frame and is fitted and fixedly connected to the tray frame and the slots. A set of side slots extends through both sides of the outer surface of each tray frame. A dual-axis motor is located between the side slots and is fixedly connected inside the tray frame. The farthest two ends of the bidirectional lead screw assembly are rotatably connected to one side of the inner wall of the side slots. The nearest two ends of the bidirectional lead screw assembly extend through the other side of the inner wall of the side slots and are fixedly connected to the two drive shafts of the dual-axis motor. A plurality of slides are provided on the top of the protective pad, spanning the top of the tray frame. Both ends of the slides are located inside the side slots and threadedly connected to the bidirectional lead screw assembly.

[0007] As a further embodiment of this utility model, a plurality of positioning posts are fixedly connected to one side of the carriage, the positioning posts being located at the top of the tray and parallel to it, and a plurality of supporting plates are fixedly connected inside the stacking rack, the supporting plates being located at the bottom of the pallet rack.

[0008] As a further embodiment of this utility model, slide rails are fixedly connected to both outer sides of the pallet frame, and one side of the slide rail is fixedly connected to the inside of the stacking rack. The pallet frame is slidably connected to the top of the receiving plate through the slide rails.

[0009] As a further embodiment of this utility model, a number of positioning rings are integrally connected to the outer wall of the stacking rack opening, and a number of pull rings are fixedly connected to the side of the pallet rack near the side groove. The positioning ring includes a plate and a positioning valve.

[0010] As a further embodiment of this utility model, the insert plate passes through the positioning ring and is inserted into the pull ring, the threaded post of the positioning valve passes through the positioning valve and the insert plate and is threadedly connected to the outer wall of the stacking rack, and several universal wheels are fixedly connected to the bottom of the stacking rack.

[0011] As a further embodiment of this utility model, the universal wheel is provided with a cylinder support, and several cylinder supports are fixedly installed at the four corners of the bottom of the stacking rack. The telescopic end of the cylinder support is fixedly installed with a rubber support, and the telescopic end of the cylinder support passes through the bottom of the stacking rack and pushes the rubber support against the ground.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The worker places the rolled-up anti-fog film tube on top of the pallet rack, with the tray fitting snugly against the curvature of the anti-fog film tube to position it. The protective pad on top of the tray is made of silicone, which increases the static friction between the film and the pallet, providing good anti-slip properties and preventing the film tube from sliding or shifting during transportation or stacking. The worker starts the dual-axis motor, which synchronously controls the rotation of the bidirectional lead screw, driving the two side carriages to move symmetrically laterally along the pallet rack. The spacing between the carriages can be automatically adjusted according to the width of the anti-fog film tube to ensure that the edge of the film is precisely aligned with the tray, avoiding wrinkles, shifts, or damage caused by positional deviations during stacking. The carriages span the top of the pallet rack and are threaded to several bidirectional lead screw groups, forming a dual-end synchronous drive to avoid tilting or jamming that may occur with single-end drive.

[0014] 2. The operator rotates the positioning valve to cancel the fixed connection of the insert plate, pulls the insert plate to remove the pull ring. The insert plate has a limiting effect on the pallet frame, preventing the pallet frame from moving out of the slide rail during the movement of the stacking rack. The operator pulls the pallet frame through the pull ring, so that the pallet frame can be pulled out laterally along the stacking rack through the slide rail, making it convenient for the operator to take out and place the anti-fog film cylinder on the pallet frame.

Several tray frames 2 are arrayed inside the stacking frame 1. Several slots 201 are opened through the top of the tray frame 2. A protective pad 202 is provided on the top of the tray frame 2. The protective pad 202 is fitted and fixedly connected to the tray frame 2 and the slots 201. A set of side slots 204 are opened through the outer sides of the tray frame 2. A dual-axis motor 4 is provided between the set of side slots 204. The dual-axis motor 4 is fixedly connected inside the tray frame 2. The farthest two ends of the bidirectional lead screw assembly 3 are rotatably connected through to one side of the inner wall of the side slot 204. The nearest two ends of the bidirectional lead screw assembly 3 are through to the other side of the inner wall of the side slot 204 and fixedly connected to the two drive shafts of the dual-axis motor 4. Several slides 5 are provided on the top of the protective pad 202. Several slides 5 span the top of the tray frame 2. The two ends of several slides 5 are located inside the side slots 204 and are threadedly connected to the bidirectional lead screw assembly 3.

[0024] When using it,

[0025] In this embodiment, a number of positioning posts 501 are fixedly connected to one side of the carriage 5. The positioning posts 501 are located at the top of the tray 201 and are parallel to it. A number of receiving plates 101 are fixedly connected inside the stacking rack 1. The receiving plates 101 are located at the bottom of the pallet rack 2.

[0026] In use, the positioning pin 501 on the slide 5 is set parallel to the bracket 201 and inserted into the positioning hole on the edge of the anti-fog film tube. The positioning pin 501 and the slide 5 provide double positioning for the anti-fog film tube, ensuring that the anti-fog film tube remains in position and fixed when the stacking rack 1 is impacted, and will not fall off.

[0027] In this embodiment, slide rails 102 are fixedly connected to both sides of the outer side of the pallet frame 2. One side of the slide rail 102 is fixedly connected to the inside of the stacking rack 1. The pallet frame 2 is slidably connected to the top of the receiving plate 101 through the slide rail 102.

[0028] In use, the support plate 101 at the bottom of the pallet frame 2 is fixed inside the stacking frame 1 with bolts, so that the load of the pallet frame 2 is evenly distributed to the uprights of the stacking frame 1, avoiding film wrinkles caused by the deformation of the pallet frame 2.

[0029] In this embodiment, a number of positioning rings 6 are integrally connected to the outer wall of the opening of the stacking rack 1, and a number of pull rings 203 are fixedly connected to the side of the pallet rack 2 near the side groove 204. The positioning ring 6 includes a plate 601 and a positioning valve 602.

[0030] In use, the operator rotates the positioning valve 602 to cancel the fixed connection of the insert plate 601, pulls the insert plate 601 to move out the pull ring 203, and pulls the pallet frame 2 through the pull ring 203, so that the pallet frame 2 can be pulled out laterally along the stacking rack 1 by the slide rail 102, making it convenient for the operator to take out and place the anti-fog film tube on the pallet frame 2.

[0031] In this embodiment, the insert plate 601 passes through the positioning ring 6 and is inserted into the pull ring 203. The threaded post of the positioning valve 602 passes through the positioning valve 602 and the insert plate 601 and is threadedly connected to the outer wall of the stacking rack 1. Several universal wheels 7 are fixedly connected to the bottom of the stacking rack 1.

[0032] When in use, after the insert plate 601 is inserted into the pull ring 203, it is tightened and fixed in the positioning ring 6 by the threaded post of the positioning valve 602, so that the position of the pallet frame 2 is fixed and it is prevented from shifting under transportation vibration. At the same time, it also prevents the stacked film from being scratched due to shaking.

[0033] In this embodiment, the universal wheel 7 is provided with a cylinder support 8 on its outside. Several cylinder supports 8 are fixedly installed at the four corners of the bottom of the stacking rack 1. Rubber supports are fixedly installed on the telescopic ends of the cylinder supports 8. The telescopic ends of the cylinder supports 8 pass through the bottom of the stacking rack 1 and push the rubber supports against the ground.

[0034] When in use, the casters 7 drive the stacking rack 1 to move in position, which facilitates short-distance movement of the device in the workshop and saves labor handling costs. After the stacking rack 1 stops moving, the cylinder support 8 is activated. The telescopic end of the cylinder support 8 descends and presses against the ground, suspending the casters 7 in the air, eliminating the vibration of the moving parts, and ensuring that the stacking rack 1 cannot be displaced during the stacking process.

[0035] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The worker places the rolled-up anti-fog film tube on top of the pallet frame 2, with the groove 201 fitting against the curvature of the anti-fog film tube to position it. The protective pad 202 on top of the groove 201 is made of silicone, increasing the static friction between the film and the pallet, providing good anti-slip properties, and preventing the film tube from sliding or shifting during transportation or stacking. The worker starts the dual-axis motor 4, which synchronously controls the bidirectional lead screw to rotate, driving the two side slides 5 to move symmetrically laterally along the pallet frame 2. The spacing of the slides 5 can be automatically adjusted according to the width of the anti-fog film tube to ensure that the film edge is flush with the groove 201. 1. Precise alignment prevents wrinkles, shifts, or damage caused by positional deviations during stacking. The slide 5 spans the top of the pallet frame 2 and is threaded to several bidirectional lead screw groups 3, forming a double-end synchronous drive to avoid tilting or jamming that may occur with single-end drive. The operator rotates the positioning valve 602 to cancel the fixed connection of the insert plate 601 and pulls the insert plate 601 to remove the pull ring 203. The insert plate 601 has a limiting effect on the pallet frame 2, preventing the pallet frame 2 from moving out through the slide rail 102 during the movement of the stacking rack 1. The operator pulls the pallet frame 2 through the pull ring 203, so that the pallet frame 2 can be pulled out laterally along the stacking rack 1 through the slide rail 102, making it convenient for the operator to pick up and place the anti-fog film cylinder on the pallet frame 2.
