[0001] This utility model belongs to the technical field of clamping and supporting bag devices, and specifically relates to a support device for cotton laboratory recycling bags. Background Technology

[0002] In cotton research laboratories, cotton samples are tested, and recycling bags are used to collect the cotton after the experiment. Currently, cloth bags are commonly used for cotton recycling. However, because cloth bags are relatively soft, people need to manually open the bags to fill them with cotton, which consumes manpower, wastes time, and affects experimental efficiency. Therefore, there is an urgent need to develop a device that eliminates the need for manual bag opening, thereby freeing up labor and improving experimental efficiency. Utility Model Content

[0003] To address the above problems, this utility model provides a support device for cotton laboratory recycling bags.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A cotton laboratory recycling bag support device includes a support frame and a clamping frame. The clamping frame is fitted onto the outside of the support frame. The inner cavity of the support frame can accommodate an open recycling bag, and the recycling bag can be placed on a support plate at the bottom of the support frame. The side of the support frame has an opening for removing the recycling bag. The top of the clamping frame is used to clamp and fix the opening of the recycling bag to the top of the support frame. The bottom of the support plate is provided with legs and a lifting mechanism that can be linked with the clamping frame. The lifting mechanism is used to drive the clamping frame to rise so that its top releases the opening of the recycling bag.

[0005] Furthermore, the support frame includes a support plate, support rods, and a support ring. The support plate and the support ring are both circular. There are three or more support rods, which are spaced apart between the support plate and the support ring. The upper end of the support rod is fixed to the bottom of the support ring, and the lower end of the support rod is fixed to the edge of the support plate.

[0006] Furthermore, the clamping frame includes a pressure ring and two lifting rods. The upper ends of the two lifting rods are symmetrically fixed to the bottom of the pressure ring, and the lower ends of the lifting rods are connected by a connecting rod. The connecting rod is located below the support plate and connected to the lifting mechanism. The upper and lower ends of the lifting rods pass through the limiting blocks and are clearance-fitted with the limiting holes on the limiting blocks. The upper and lower ends of the support rod are fixed to the limiting blocks, and the lifting rods are arranged side by side on the outside of the support rod. The inner diameter of the pressure ring is larger than the outer diameter of the support ring, and the length of the lifting rod is greater than the sum of the length of the support rod and the outer diameter of the support ring.

[0007] Furthermore, the lifting mechanism includes a rocker arm, a support, and a pedal. One inner end of the rocker arm is connected to the middle of a connecting rod. The pedal is located on the top surface of the other end of the rocker arm and is located on the outer side of the support plate. The support is located in the middle of the radius of the support plate. The rocker arm has an upward bend in the middle, and the rocker arm at the bend is rotatably connected to the support.

[0008] Furthermore, one end of the rocker arm is rotatably connected to the telescopic component, which is located on the side of the connecting rod; the support ring is equipped with a pressure sensor that is linked to the telescopic component.

[0009] Furthermore, the telescopic component is a cylinder, a hydraulic cylinder, or an electric push rod, the upper end of the telescopic component is rotatably connected to the bottom of the support plate, and the movable end of the telescopic component is rotatably connected to the end of the rocker arm.

[0010] Furthermore, both the support frame and the clamping frame are made of stainless steel.

[0011] Furthermore, there are three or more support legs, which are evenly distributed around the bottom perimeter of the support plate.

[0012] Furthermore, the bottom of the support leg is provided with casters, and there are four support legs and four casters.

[0013] The technological advancements achieved by this invention compared to existing technologies are as follows: This invention involves placing a recycling bag inside a support frame. The bag's opening can be flipped open and rests on the top edge of the support frame. Under gravity, a clamping frame descends, clamping the bag's opening tightly against the top of the support frame, preventing hand pinching. When the bag is filled to a certain volume of cotton, a lifting mechanism raises the clamping frame, releasing the bag's opening and allowing it to be removed through a side opening of the support frame. This invention features a simple and compact structure, is easy to use, and eliminates the need for manual bag holding, thus freeing up labor and improving work efficiency. Furthermore, its low manufacturing cost facilitates widespread application. Attached Figure Description

Detailed Implementation

[0016] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0017] like Figure 1 , Figure 2 As shown, a cotton laboratory recycling bag support device includes a support frame 1 and a clamping frame 2. The clamping frame 2 is fitted onto the outside of the support frame 1. The inner cavity of the support frame 1 can accommodate an open recycling bag 00, and the recycling bag 00 can be placed on a support plate 11 at the bottom of the support frame 1. The side of the support frame 1 is provided with an opening for removing the recycling bag 00. The top of the clamping frame 2 is used to clamp and fix the bag opening of the recycling bag 00 to the top of the support frame 1. The bottom of the support plate 11 is provided with a support leg 10 and a lifting mechanism 3 that can be linked with the clamping frame 2. The lifting mechanism 3 is used to drive the clamping frame 2 to rise so that its top releases the bag opening of the recycling bag 00.

[0018] Before use, place the unfolded recycling bag inside the support frame. Use the lifting mechanism to raise the clamping frame, flipping the bag opening over and placing it on the top edge of the support frame. The clamping frame then lowers under its own weight, clamping the bag opening tightly against the top of the support frame, thus flipping the bag over. When the bag is filled with cotton to a certain amount, use the lifting mechanism again to raise the clamping frame, releasing the bag opening at the top. The bag can then be removed through the side opening of the support frame. Place the empty recycling bag inside the support frame and repeat the above steps.

[0019] As a preferred structure, such as Figure 1 , 3As shown, the support frame 1 includes a support plate 11, support rods 12, and a support ring 13. Both the support plate 11 and the support ring 13 are circular. There are three or more support rods 12, spaced apart between the support plate 11 and the support ring 13. The upper end of each support rod 12 is fixed to the bottom of the support ring 13, and the lower end of each support rod 12 is fixed to the edge of the support plate 11. In this embodiment, there are three support rods 12, and the gap between two adjacent support rods 12 forms an opening for easy removal of the recycling bag 00. Specifically, two support rods are arranged along the diameter of the support plate, and the third support rod is located in the middle of the semi-circular edge of the side.

[0020] Of course, the support frame is not limited to Figure 1 The structure can use a curved plate instead of a support rod. The curved plate, together with the support ring and the support plate, forms a semi-enclosed barrel that can hold the recycling bag. The side of the barrel has an opening for easy removal of the recycling bag.

[0021] In specific embodiments of this utility model, such as Figure 3 , 4 As shown, the clamping frame 2 includes a pressure ring 21 and two lifting rods 22. The upper ends of the two lifting rods 22 are symmetrically fixed to the bottom of the pressure ring 21, and the lower ends of the lifting rods 22 are connected by a connecting rod 23. The connecting rod 23 is located below the support plate 11 and connected to the lifting mechanism 3. The upper and lower ends of the lifting rods 22 respectively pass through the limiting blocks 4 and are clearance-fitted with the limiting holes on the limiting blocks 4. The upper and lower ends of the support rod 12 are respectively fixed to the limiting blocks 4, and the lifting rods 22 are arranged side by side on the outside of the support rod 12. The inner diameter of the pressure ring 21 is larger than the outer diameter of the support ring 13, and the length of the lifting rod 22 is greater than the sum of the length of the support rod 12 and the outer diameter of the support ring 13. The clamping frame with this structure can press and fix the bag opening of the recycling bag between the pressure ring and the support ring under the action of gravity. At the same time, the limiting blocks play a limiting role during the lifting of the lifting rods.

[0022] The limiting block can be a rectangular block with two through holes machined at both ends. One through hole is tightly fitted to the support rod, and the other through hole is loosely fitted to the lifting rod to facilitate the up and down movement of the lifting rod.

[0023] In specific embodiments of this utility model, such as Figure 3As shown, the lifting mechanism 3 includes a rocker arm 31, a support 32, and a pedal 33. One inner end of the rocker arm 31 is connected to the middle of the connecting rod 23. The pedal 33 is located on the top surface of the other end of the rocker arm 31 and is positioned on the outer side of the support plate 11. The support 32 is located at the center of the radius of the support plate 11. The rocker arm 31 has an upward bend in the middle, and the rocker arm 31 at the bend is rotatably connected to the support 32. This lifting mechanism uses a lever principle; stepping on the pedal raises the inner end of the rocker arm, which in turn raises the connecting rod and the lifting rod, facilitating the removal of the recycling bag. Conversely, releasing the pedal causes the clamping frame to fall back under gravity, and the pressure ring falls to the outer side and slightly below the support ring.

[0024] Further optimize the above solution, such as Figure 3 As shown, one end of the rocker arm 31 is rotatably connected to the telescopic component 5, which is located on the side of the connecting rod 23. A pressure sensor (not shown) linked to the telescopic component 5 is mounted on the support ring 13. The telescopic component 5 is a cylinder, hydraulic cylinder, or electric push rod. Its upper end is rotatably connected to the bottom of the support plate 11, and its movable end is rotatably connected to the end of the rocker arm 31. The pressure sensor can be a piezoelectric sensor, embedded in the side wall of the support ring. The piezoelectric sensor and the telescopic component are connected to a controller in the laboratory. When the pressure sensed by the piezoelectric sensor reaches a set value (the weight of the cotton fully loaded in the recycling bag), a full-load signal is sent to the controller. The controller then sends an action command to the telescopic component, which drives the rocker arm and lifting rod to rise. The bag opening can be released without stepping on a pedal, facilitating the removal of the recycling bag and further improving the automation level of the device.

[0025] In actual manufacturing, both the support frame 1 and the clamping frame 2 are made of stainless steel. The support rod 12, support ring 13, pressure ring 21 and lifting rod 22 are all made of stainless steel pipe. The cable connecting the pressure sensor and the telescopic component 5 can be laid inside the stainless steel pipe of the support ring 13 and the support rod 12.

[0026] In addition, there are three or more support legs 10, which are evenly distributed around the bottom perimeter of the support plate 11; the bottom of each support leg 10 is equipped with casters 6. Figure 1 In the illustrated embodiment, there are four support legs 10 and four casters 6, which ensures the stability of the device. Casters with brakes can also be used, allowing the device to be moved to any work location and then braked to maintain stability.

[0027] In summary, this invention has the advantages of simple and compact structure, convenient and quick use, and low manufacturing cost. By stepping on the pedal, the pressure ring is raised, opening the recycling bag and placing its opening on the support ring. Releasing the pedal causes the pressure ring and lifting rod to fall back under their own weight, preventing hand pinching. The descending pressure ring clamps and secures the bag opening to the support ring, thus achieving the flipping of the recycling bag. During the experiment, when the recycling bag is full of cotton and its weight reaches a set value, the piezoelectric sensor sends a command to the telescopic component via the controller, automatically raising the lifting rod and causing the pressure ring to rise. The recycling bag can then be removed through the gap in the support rod. This invention eliminates the need for manual bag opening, facilitating cotton collection, freeing up labor, and improving work efficiency. Furthermore, this solution is simple to manufacture, low in cost, and easy to promote and apply.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
