Description

Technical Field

[0001] This utility model relates to the field of adhesive bandage production technology, and in particular to a cardboard folding device for adhesive bandage production. Background Technology

[0002] In the automated production of bandages, there is a large gap between the cutter and the roller. When the material is transported in a narrow strip, the strip is prone to deviate when it enters the cutter due to its poor rigidity, which leads to increased cutting error and poor feeding stability. Summary of the Invention

[0003] The technical problem to be solved by this invention is that narrow strips are prone to unstable support and deviation when conveyed between rollers and cutters.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cardboard folding device for producing bandages, including a frame, a mounting plate vertically fixedly connected to the middle of the frame, and a feeding plate horizontally rotatably mounted in the middle of the mounting plate. The bottom and top of the mounting plate are respectively provided with a bottom clamping plate and a top clamping plate distributed in a conical shape. The mounting plate is provided with an adjusting component for adjusting the distance between the ends of the bottom clamping plate and the top clamping plate. The ends of the bottom clamping plate and the top clamping plate are located on one side of a pair of cutting rollers arranged in the frame.

[0005] Preferably, a support shaft is horizontally fixedly connected to the side wall of the mounting plate, and a clamping block is fixedly connected to the bottom of the feeding plate. The clamping block is rotatably connected to the support shaft, and a notch is provided at one end of the clamping block, with a locking bolt threadedly connected to the notch.

[0006] Preferably, the feeding plate is an arc-shaped plate, and limit strips are provided on both sides of the feeding plate.

[0007] Preferably, the adjustment assembly includes a first sliding plate and a second sliding plate that are respectively tilted and fixedly connected to the mounting plate. The side walls of the first sliding plate and the second sliding plate are provided with grooves along the length direction. The bottom clamping plate and the top clamping plate are respectively slidably connected in the grooves of the first sliding plate and the second sliding plate. The adjustment assembly also includes a locking structure that locks the bottom clamping plate and the top clamping plate in the grooves respectively.

[0008] Preferably, the locking structure includes a connecting plate fixedly connected to the mounting plate, a first sliding rod slidably disposed on the connecting plate, the bottom clamping plate being inclined and its top end facing the upright frame, a movable shaft being connected to the top end of the bottom clamping plate, the movable end of the first sliding rod abutting against the bottom of the movable shaft, a locking block being connected to the first sliding rod, and a positioning hole for the locking block to be inserted into the corresponding groove of the first sliding rod.

[0009] Preferably, the top clamping plate is arranged at an angle with its bottom end facing the upright frame. A second sliding rod is slidably connected to the connecting plate. Both ends of the top clamping plate end wall are connected to a movable shaft and slidably connected to the second sliding plate through the movable shaft. The upper movable shaft is connected to a connecting arm, and the end of the connecting arm is fixedly connected to the external frame through a connector. The top end of the second sliding rod abuts against the bottom of the movable shaft below the displacement. A locking block is connected to the second sliding rod, and a positioning hole for the locking block to be inserted is provided in the corresponding groove of the second sliding rod.

[0010] Preferably, a strip-shaped mounting groove is vertically arranged inside the frame, and a pair of cutting rollers are stacked in the mounting groove. Y-shaped support rollers are provided at the inner top and inner bottom of the frame, and the Y-shaped support rollers are distributed on both sides of the cutting rollers.

[0011] This utility model provides a cardboard folding device for manufacturing bandages, which has the following beneficial effects.

[0012] 1. The device forms a continuous support structure of "pre-guidance - precise clamping - stable conveying" through an arc-shaped feeding plate and a conical bottom clamping plate and a top clamping plate: the limiting strips on both sides of the arc-shaped feeding plate can initially constrain the narrow strip and avoid deviation in the early stage of conveying; the bottom clamping plate and the top clamping plate converge in a conical shape towards the cutting roller, and their ends precisely connect to one side of the cutting roller, filling the gap between the roller and the cutter, and providing uninterrupted support for the strip throughout the entire process.

[0013] 2. The adjustment component can flexibly adjust the end distance between the bottom clamping plate and the top clamping plate through the sliding groove structure of the first and second sliding plates. When the bottom clamping plate is slid, the first sliding rod abuts against the moving shaft to adjust the height, and the locking block is inserted into the positioning hole to lock the position. The top clamping plate achieves fine adjustment of the distance through the cooperation of the moving shaft and the second sliding rod. While adjusting the distance between the top clamping plate and the bottom clamping plate, the distance between the clamping plate structure and the cutting roller is also adjusted. When dealing with cutting rollers of different sizes, it can ensure that the feeding gap is small enough to improve the stability of feeding. Attached Figure Description

[0018] like Figure 1-3 As shown, this utility model proposes a cardboard folding device for producing bandages, including a frame 2, a mounting plate 1 vertically fixedly connected to the middle of the frame 2, and a feeding plate 5 horizontally rotatably mounted in the middle of the mounting plate 1. The bottom and top of the mounting plate 1 are respectively provided with a bottom clamping plate 12 and a top clamping plate 14 distributed in a conical shape. The mounting plate 1 is provided with an adjusting component for adjusting the distance between the ends of the bottom clamping plate 12 and the top clamping plate 14. The ends of the bottom clamping plate 12 and the top clamping plate 14 are located on one side of the cutter rollers 3 arranged in pairs inside the frame 2.

[0019] The material belt is fed by the feeding plate 5 in conjunction with the bottom clamping plate 12 and the top clamping plate 14. During the feeding process, the material first passes through the feeding plate 5, which supports the material belt. Then the material belt passes through the gap between the ends of the bottom clamping plate 12 and the top clamping plate 14. The top of the bottom clamping plate 12 supports the material belt. Then the material belt enters between the two cutting rollers 3. The drive motor on the mounting frame 2 drives one cutting roller 3 to rotate. The same end of the two cutting rollers 3 is driven by the meshing of the gear set, so that the two cutting rollers 3 rotate synchronously in opposite directions to cut the material belt.

[0020] As a preferred embodiment of this utility model, a support shaft 4 is horizontally fixedly connected to the side wall of the mounting plate 1, and a clamping block is fixedly connected to the bottom of the feeding plate 5. The clamping block is rotatably connected to the support shaft 4. One end of the clamping block has a notch, and a locking bolt is threadedly connected to the notch. The clamping block is a rectangular block with a circular connecting hole in the middle. When the feeding plate 5 is installed, the mounting plate is rotatably mounted on the support shaft 4 by the clamping block. A notch is provided on one side of the clamping block, connecting the outside and the connecting hole. The size of the notch is adjusted by bolts. When the notch is small enough, the top and bottom of the clamping block divided by the notch can clamp the connecting hole, thereby stably clamping the clamping block on the support shaft 4 and fixing the angle of the feeding plate 5.

[0021] like Figure 1 and Figure 2 As shown. The feeding plate 5 is an arc-shaped plate, and limit strips are provided on both sides of the feeding plate 5. The limit strips play a certain limiting role, which can ensure that the material strip smoothly enters between the two cutting rollers 3.

[0022] like Figure 2 and Figure 3As shown. The adjustment assembly includes a first sliding plate 13 and a second sliding plate 7, which are respectively tilted and fixedly connected to the mounting plate 1. Both the first sliding plate 13 and the second sliding plate 7 have grooves along their length on their sidewalls. The bottom clamping plate 12 and the top clamping plate 14 are slidably connected within the grooves of the first sliding plate 13 and the second sliding plate 7, respectively. The adjustment assembly also includes locking structures that lock the bottom clamping plate 12 and the top clamping plate 14 within the grooves. The installation of the first sliding plate 13 and the second sliding plate 7 is used to limit the angle of the bottom clamping plate 12 and the top clamping plate 14. The grooves allow adjustment of the gap between the bottom clamping plate 12 and the top clamping plate 14 and the cutting roller 3. When using different sized cutting rollers 3 to cut bandages of different lengths, the bottom clamping plate 12 and the top clamping plate 14 can still meet the feeding requirements.

[0023] like Figure 2 and Figure 3 As shown. The locking structure includes a connecting plate 6 fixedly connected to the mounting plate 1, a first sliding rod 8 slidably disposed on the connecting plate 6, a bottom clamping plate 12 inclinedly arranged with its top end facing the upright frame 2, a moving shaft 9 connected to the top end of the bottom clamping plate 12, the movable end of the first sliding rod 8 abutting against the bottom of the moving shaft 9, a locking block 10 connected to the first sliding rod 8, and a positioning hole for the locking block 10 to be inserted into the corresponding groove of the first sliding rod 8. When adjusting the position of the bottom clamping plate 12, the bottom clamping plate 12 moves along the slotted groove on the first sliding plate 13. After moving to the set position, the first sliding rod 8 on the sliding connecting plate 6 is slid so that the end of the first sliding rod 8 abuts against the moving shaft 9 on the bottom clamping plate 12. Then, by rotating the locking block 10, the locking block 10 is inserted into the corresponding positioning hole, thereby fixing the first sliding rod 8. The first sliding rod 8 abutting against the moving shaft 9 can prevent the bottom clamping plate 12 from sliding down.

[0024] like Figure 2 and Figure 3 As shown. The top clamping plate 14 is arranged at an angle, with its bottom end facing the upright frame 2. A second sliding rod 11 is slidably connected to the connecting plate 6. Both ends of the end wall of the top clamping plate 14 are connected to a moving shaft 9, which is slidably connected to the second sliding plate 7. The upper moving shaft 9 is connected to a connecting arm 15, and the end of the connecting arm 15 is fixedly connected to the external frame through a connector. The top end of the second sliding rod 11 abuts against the bottom of the moving shaft 9 below the displacement. A locking block 10 is connected to the second sliding rod 11, and a positioning hole for the locking block 10 to be inserted is provided in the corresponding groove of the second sliding rod 11. The top end of the connecting arm 15 is fixedly connected to the external frame. The connecting arm 15 is a fixed structure. When it is necessary to rotate its bottom, the connecting bolts between the bottom and the top end need to be loosened. The top end of the top clamping plate 14 is pulled by the connecting arm 15, and then the corresponding second sliding rod 11 abuts against the moving shaft 9 at the bottom end of the top clamping plate 14, thereby fixing the top clamping plate 14.

[0025] like Figure 1-3 As shown, a vertically arranged strip-shaped mounting groove is provided inside the support frame 2. A pair of cutting rollers 3 are stacked and arranged in the mounting groove. Y-shaped support rollers are provided at both the inner top and inner bottom of the support frame 2, and the Y-shaped support rollers are distributed on both sides of the cutting rollers 3. The top and bottom rotating support method, combined with the mounting groove on the support frame 2, provides stable rotating support for the two cutting rollers 3, ensuring the stability of the rotation of the two cutting rollers 3. At the same time, this rotating installation method allows workers to quickly replace and maintain the cutting rollers 3.
