Description

Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, and in particular to a water-soluble film feeding mechanism with automatic unwinding function. Background Technology

[0002] A water-soluble film feeding mechanism refers to mechanical equipment used to supply and transport water-soluble films. It typically includes components such as an unwinding device, a guiding device, a tension control system, a cutting device, and a winding device. These mechanisms ensure a stable and continuous supply of water-soluble films during the production process to meet different production needs.

[0003] In the prior art, Chinese patent CN213679100U discloses a water-soluble film driven unwinding device. A tension detection mechanism is installed between the traditional water-soluble film roll and the mold to detect the tension of the water-soluble film in real time, keeping it within a reasonable range. This solves the problems of water-soluble film folding due to insufficient tension and tearing due to excessive tension. However, in practical applications, water-soluble film feeding mechanisms with automatic unwinding functions are prone to uneven tension on the surface of the unwound water-soluble film. Most existing unwinding devices require manual adjustment after detecting uneven tension, and the adjusted water-soluble film needs to be inspected afterward. To avoid excessive adjustment angles that could damage the water-soluble film, the water-soluble film feeding device adjusts only a small range each time. Therefore, the feeding device needs to be adjusted multiple times to achieve a more balanced tension, affecting the feeding speed and reducing production efficiency. Therefore, we disclose a water-soluble film feeding mechanism with automatic unwinding function. Utility Model Content

[0004] The purpose of this invention is to propose a water-soluble film feeding mechanism with automatic unwinding function to solve the problem of uneven tension on the film surface and the problem of reduced water-soluble film production efficiency.

[0005] To achieve the above objectives, this utility model provides a water-soluble film feeding mechanism with automatic unwinding function, including a base plate frame. Several adjusting frames are fixedly connected to the top of the base plate frame. Telescopic sleeves are fixedly connected to both the upper and lower ends of each adjusting frame. A telescopic rod is movably sleeved within each telescopic sleeve. A spring is fixedly connected to one end of each telescopic rod, and the spring is fixedly connected to the adjusting frame. A ball is movably engaged at one end of the telescopic rod extending from the telescopic sleeve. A fixing block is fixedly connected between two balls. A first rotating groove is formed at one end of the fixing block. An adjusting shaft is rotatably connected within the first rotating groove. A connecting frame is fixedly connected to the other end of the fixing block extending from the adjusting frame. A water-soluble film body is attached to the outer wall of the adjusting shaft. A drive motor is fixedly connected to the top of the base plate frame. An unwinding shaft is rotatably connected to the top of the base plate frame. The unwinding shaft is wound around the water-soluble film body. The output end of the drive motor is fixedly sleeved with the unwinding shaft.

[0006] Preferably, there are four adjustment frames, with two adjustment frames forming a group, and each group of adjustment frames is symmetrically distributed around the transverse central axis of the adjustment shaft.

[0007] Preferably, there are two adjusting shafts and two connecting frames. The two adjusting shafts have different heights relative to the horizontal plane. The adjusting shafts are located between the adjusting frames. The adjusting shafts are I-shaped. The first rotating groove is a T-shaped groove. Both ends of the adjusting shafts are rotatably connected to the first rotating groove. The connecting frame is a U-shaped frame. Both ends of the connecting frame are fixedly connected to the fixing block.

[0008] Preferably, the outer wall of the adjusting shaft is fixedly connected with a plurality of annularly distributed anti-slip plates, which are made of silicone.

[0009] Preferably, two detection frames are fixedly connected to the top of the base plate frame, and a detection shaft is provided between the two detection frames. The detection shaft is in contact with the water-soluble membrane body. A limiting hole is opened at the top of the detection frame, and a limiting block is sleeved in the limiting hole. A second rotating groove is opened at one end of the limiting block. Both ends of the detection shaft are rotatably connected in the second rotating groove. A limiting plate is fixedly connected to the other end of the limiting block that passes through the limiting hole. A pressure detector is fixedly connected to the upper end of the detection frame, and the top of the pressure detector extends to the bottom end of the limiting hole and is in contact with the limiting block.

[0010] Preferably, the limiting block is a rectangular block, the limiting block and the limiting plate form a T-shape, and the two adjusting shafts are located between the drive motor and the detection frame.

[0011] The beneficial effects of this utility model are as follows: In use, the position of the adjustment frame is fixed by the base plate frame, and the position of the telescopic sleeve and the spring are fixed by the adjustment frame. This allows the telescopic sleeve to limit the movement direction of the telescopic rod, and the spring to limit the movement range of the telescopic rod. The rotation range of the ball is limited by the telescopic rod, so that the movement direction and distance of the fixed block are limited by the ball and the telescopic rod. This also allows the fixed block to move at multiple angles. The fixed block limits the position of the adjustment shaft by the first rotation groove, so that the adjustment shaft can adjust the tension of various parts of the water-soluble membrane body. When the tension of the water-soluble membrane body changes, it will squeeze the adjustment shaft, causing the fixed block to move at multiple angles. This will cause the corresponding ball and spring to adjust accordingly, changing the tension of various parts of the water-soluble membrane body. This will restore the tension of various parts of the water-soluble membrane body to a more uniform state, resulting in better tension adjustment of the water-soluble membrane body. This will reduce the probability of workers having to stop the machine to adjust the tension of the water-soluble membrane body, thereby improving the production efficiency of the water-soluble membrane body.

[0012] Two detection frames restrict the position of the detection shaft, thus limiting the movement of the water-soluble film body. The detection frames limit the position of the limiting block through the limiting hole, and the limiting block limits the rotation of the detection shaft through the second rotating groove. The limiting plate improves the stability of the limiting block within the limiting hole. The pressure detector detects the pressure of the limiting block, and then detects the pressure at both ends of the detection shaft, thereby measuring whether the pressure applied by the water-soluble film body to both ends of the detection shaft is within the qualified range. If it is unqualified, a warning is issued to ensure that the tension of the water-soluble film body is qualified after unwinding. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0019] like Figures 1-3As shown, a water-soluble film feeding mechanism with automatic unwinding function includes a base frame 1. Several adjusting frames 2 are fixedly connected to the top of the base frame 1. Telescopic sleeves 8 are fixedly connected to both the upper and lower ends of each adjusting frame 2. Telescopic rods 7 are movably sleeved inside the telescopic sleeves 8. A spring 9 is fixedly connected to one end of the telescopic rod 7, and the spring 9 is fixedly connected to the adjusting frame 2. A ball 6 is movably engaged at one end of the telescopic rod 7 extending from the telescopic sleeve 8. A fixing block 3 is fixedly connected between two balls 6. A first rotating groove 4 is opened at one end of the fixing block 3. An adjusting shaft 5 is rotatably connected within the first rotating groove 4. A connecting frame 10 is fixedly connected to the other end of the fixing block 3 extending from the adjusting frame 2. A water-soluble film body 12 is attached to the outer wall of the adjusting shaft 5. There are four adjusting frames 2, two of which are... Each set of adjustment frames 2 is symmetrically distributed around the transverse central axis of the adjustment shaft 5. There are two adjustment shafts 5 and two connecting frames 10. The two adjustment shafts 5 have different heights relative to the horizontal plane. The adjustment shafts 5 are located between the adjustment frames 2. The adjustment shafts 5 are I-shaped, and the first rotating groove 4 is a T-shaped groove. Both ends of the adjustment shaft 5 are rotatably connected to the first rotating groove 4. The connecting frame 10 is a U-shaped frame, and both ends of the connecting frame 10 are fixedly connected to the fixing block 3. Several annularly distributed anti-slip plates made of silicone are fixedly connected to the outer wall of the adjustment shaft 5. A drive motor 11 is fixedly connected to the top of the base plate frame 1, and a unwinding shaft is rotatably connected to the top of the base plate frame 1. The unwinding shaft is wound around the water-soluble film body 12. The output end of the drive motor 11 is fixedly connected to the unwinding shaft. In use, a series of adjustable brackets 2 are fixedly connected to the top of the base plate 1, fixing the position of the adjustable brackets 2. Telescopic sleeves 8 are fixedly connected to both ends of the adjustable brackets 2. A telescopic rod 7 is movably sleeved inside the telescopic sleeve 8. A spring 9 is fixedly connected to one end of the telescopic rod 7, and the spring 9 is fixedly connected to the adjustable bracket 2, fixing the position of the telescopic sleeve 8 and the spring 9. This restricts the direction of movement of the telescopic rod 7 through the telescopic sleeve 8 and limits the range of movement of the telescopic rod 7 through the spring 9. A ball 6 is movably engaged at one end of the telescopic rod 7 extending from the telescopic sleeve 8. A fixing block 3 is fixedly connected between two balls 6, restricting the rotation range of the balls 6 through the telescopic rod 7 and limiting the direction and distance of movement of the fixing block 3. The sphere 6 and telescopic rod 7 restrict movement, allowing the fixed block 3 to move at multiple angles. A first rotating groove 4 is provided at one end of the fixed block 3, within which an adjusting shaft 5 is rotatably connected. The fixed block 3 restricts the position of the adjusting shaft 5 via the first rotating groove 4. A connecting frame 10 is fixedly connected to the other end of the adjusting frame 2 extending from the fixed block 3, further restricting the position of the adjusting shaft 5 and ensuring stable movement. A water-soluble film body 12 is attached to the outer wall of the adjusting shaft 5, allowing the adjusting shaft 5 to adjust various tensions of the water-soluble film body 12. Changes in the tension of the water-soluble film body 12 compress the adjusting shaft 5, causing the fixed block 3 to move at multiple angles, thereby adjusting the corresponding sphere 6 and spring 9.By altering the tension at various points on the water-soluble film body 12, the tension of the water-soluble film body 12 is restored to a more uniform state, resulting in better tension adjustment and reducing the probability of workers having to stop to adjust the tension of the water-soluble film body 12. This improves the feeding efficiency of the water-soluble film body 12. There are four adjusting frames 2, with two adjusting frames 2 forming a group. Each group of adjusting frames 2 is symmetrically distributed around the transverse central axis of the adjusting shaft 5, thus restricting the position of the adjusting shaft 5. There are two adjusting shafts 5 and two connecting frames 10. The two adjusting shafts 5 have different heights relative to the horizontal plane, allowing the adjusting shaft 5 to adjust the water-soluble film body 12 twice, resulting in more uniform tension of the unwound water-soluble film body 12, which is beneficial for subsequent production processes. The adjusting shaft 5 is located between the adjusting frames 2. The adjusting shaft 5 is I-shaped, and the first rotating groove 4 is a T-shaped groove. Both ends of the adjusting shaft 5 are rotatably connected to the first rotating groove 4, so that the two first rotating grooves 4 cooperate to restrict the position of the adjusting shaft 5, thereby allowing the adjusting shaft 5 to adjust according to the horizontal plane. When the tension of the water-soluble membrane body 12 changes and moves at multiple angles, it will not detach from the connection with the fixed block 3. The connecting frame 10 is a U-shaped frame, with both ends fixedly connected to the fixed block 3. This allows the adjusting shaft 5 to move by moving the fixed block 3, and the connecting frame 10 can then drive the other end of the adjusting shaft 5 to adjust accordingly. This ensures smooth movement of the adjusting shaft 5 and reduces the risk of damage to the water-soluble membrane body 12 during adjustment. Several annularly distributed anti-slip plates, made of silicone, are fixedly connected to the outer wall of the adjusting shaft 5, making the relative position between the adjusting shaft 5 and the water-soluble membrane body 12 more stable and facilitating the adjustment of the tension of the water-soluble membrane body 12. A drive motor 11 is fixedly connected to the top of the base plate frame 1, and an unwinding shaft is rotatably connected to the top of the base plate frame 1. The unwinding shaft is wound around the water-soluble membrane body 12, and the output end of the drive motor 11 is fixedly sleeved with the unwinding shaft. This fixes the position of the drive motor 11 on the base plate frame 1, allowing the drive motor 11 to drive the unwinding shaft to rotate and unwind the water-soluble membrane body 12.

[0020] As a preferred embodiment of this example, Figure 1 and Figure 3As shown, two detection frames 13 are fixedly connected to the top of the base plate frame 1. A detection shaft 14 is provided between the two detection frames 13. The detection shaft 14 is in contact with the water-soluble film body 12. A limit hole 18 is opened at the top of the detection frame 13. A limit block 15 is sleeved in the limit hole 18. A second rotating groove 17 is opened at one end of the limit block 15. Both ends of the detection shaft 14 are rotatably connected in the second rotating groove 17. A limit plate 16 is fixedly connected to the other end of the limit block 15 that passes through the limit hole 18. A pressure detector 19 is fixedly connected to the upper end of the detection frame 13. The top of the pressure detector 19 extends to the bottom of the limit hole 18. The end of the limiting block 15 is attached to the limiting block 15, which is a rectangular block. The limiting block 15 and the limiting plate 16 form a T-shape. Two adjusting shafts 5 are located between the drive motor 11 and the detection frame 13. Two detection frames 13 are fixedly connected to the top of the base plate frame 1. A detection shaft 14 is provided between the two detection frames 13. The detection shaft 14 is attached to the water-soluble film body 12, so that the two detection frames 13 can limit the position of the detection shaft 14, thereby limiting the movement of the water-soluble film body 12. A limiting hole 18 is opened at the top of the detection frame 13, and a limiting block 15 is sleeved in the limiting hole 18. One end of the limiting block 15... The detection shaft 14 has a second rotating groove 17 at one end, and both ends are rotatably connected to the second rotating groove 17. This allows the detection frame 13 to limit the position of the limiting block 15 through the limiting hole 18, and in turn, the limiting block 15 to limit the rotation position of the detection shaft 14 through the second rotating groove 17. A limiting plate 16 is fixedly connected to the other end of the limiting block 15 that extends through the limiting hole 18, thereby improving the stability of the limiting block 15 within the limiting hole 18. A pressure detector 19 is fixedly connected to the upper end of the detection frame 13, and the top end of the pressure detector 19 extends to the bottom end of the limiting hole 18 and fits against the limiting block 15. The pressure detector 19 detects the pressure of the limiting block 15, and then detects the pressure at both ends of the detection shaft 14, thereby measuring whether the pressure applied by the water-soluble film body 12 to both ends of the detection shaft 14 is within the qualified range. If it is unqualified, an alarm is issued to ensure that the tension of the water-soluble film body 12 after unwinding is qualified. The limiting block 15 is a rectangular block, and the limiting block 15 and the limiting plate 16 form a T-shape, so that the position of the limiting block 15 in the limiting hole 18 is stable. The two adjusting shafts 5 are located between the drive motor 11 and the detection frame 13, so that the detection frame 13 detects the tension of the water-soluble film body 12 after the tension is adjusted by the adjusting shafts 5.
