Description

Technical Field

[0001] This invention relates to the field of thin film processing technology, specifically to a thin film loading mechanism. Background Technology

[0002] A film is a thin, flexible, transparent sheet made of plastics, adhesives, rubber, or other materials. Scientifically, a film is a two-dimensional material formed by the deposition of atoms, molecules, or ions onto a substrate surface. In the packaging machinery industry, packaging equipment that integrates bag making, metering, filling, and sealing is relatively mature. As long as standard packaging film rolls and materials are provided, the equipment can automatically complete the entire packaging process. Currently, there are various methods for installing film rolls in packaging machines, including rod-type, roller-supported film type, and top-clamping type.

[0003] Patent publication number CN104150019B discloses a film roll loading mechanism. It is fixed to the rear of a packaging machine frame via a frame fixing plate. Two guide rod fixing plates are symmetrically installed on both sides of the frame fixing plate. The two ends of two guide rods are fixed to the two guide rod fixing plates respectively. Two film roll side plates are respectively installed on the two guide rods, and the two film roll side plates can slide along the two guide rods. A left-hand tip is installed at the front of the left film roll side plate, and a right-hand tip is symmetrically installed at the front of the right film roll side plate. The left tip is connected to a motor reducer via a transmission assembly. A cylinder mounting seat is also installed inside the left film roll side plate, and the cylinder is fixed to the cylinder mounting seat through a mounting hole. The other end of the cylinder is connected to the right film roll side plate via a cylinder connector assembly. A guide rod is installed above the guide rod fixing plate, and a film support plate is fitted in the middle of the inner side of the film roll side plate. The film support plate can rotate around the guide rod. This mechanism has a simple structure, provides stable and reliable functions, occupies little space, and can be integrated with a packaging machine.

[0004] While the existing technology CN104150019B has many advantages in use, it still has the following problems: it drives the film roll to rotate by a motor, but the weight of the motor makes the equipment heavy, affecting the smoothness of the equipment's movement and easily causing damage to the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a thin film loading mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a film loading mechanism, comprising a vertical plate, a motor body, and a rotating shaft. A lead screw body is mounted on each of the two outer walls of the vertical plate. Side plates are respectively provided on the two outer walls of the lead screw body. A rotating shaft is rotatably mounted inside the side plates. A movable groove is formed on the inner wall of the rotating shaft. A slider is movably mounted inside the movable groove. A support rod is mounted on the outer wall of one end of the slider. A motor body is mounted on one outer wall of the vertical plate. A connecting plate is provided on the outer wall of one end of both the support rod and the motor body. A circular array of support blocks is mounted on the outer wall of the connecting plate. A circular array of fixing blocks is mounted on one outer wall of the connecting plate.

[0007] When using one of the film loading mechanisms in this technical solution, the operator places the film roll on the upper part of the pallet, and the pressure sensor detects the weight of the film roll to avoid damage to the equipment. The electric push rod pushes the film roll to move vertically until the film roll is aligned with the axis of the clamping head. The side plate moves horizontally outside the screw body, thereby adjusting the distance between the two clamping heads so that the clamping heads clamp and fix the film roll. The motor body drives the connecting rod, rotating shaft, clamping head and film roll to rotate circumferentially through the magnet body and connecting plate, thereby causing the film roll material to be actively released.

[0008] Preferably, a motor is provided on the outer wall of one end of the lead screw body, and the motor can drive the lead screw body to rotate in a circular motion, thereby driving the side plate to move horizontally. The threaded openings on both sides of the lead screw body are in opposite directions, thereby adjusting the distance between the two side plates so that the distance between the side plates conforms to the size of the film roll.

[0009] Preferably, clamping heads are installed on the outer walls of the two rotating shafts on opposite sides. The two clamping heads can clamp and fix the film roll, ensuring that the film roll is stably positioned between the side plates.

[0010] Preferably, electric push rods are installed on both sides of the lower outer wall of the upright plate, and pressure sensors are installed on the upper outer wall of the electric push rods. A support plate is installed on the upper outer wall of the pressure sensor. The inner wall of the support plate is designed with an arc shape. The support plate can support the film roll, and the pressure sensor detects the weight of the film roll to prevent the weight of the film roll from exceeding the equipment's load-bearing capacity.

[0011] Preferably, magnet bodies are installed on both outer walls of the connecting plate, and a partition plate is installed between the magnet bodies to separate the magnetic forces of the two magnet bodies. The mutual attraction between the magnet bodies enables the motor body to drive the support rod to rotate.

[0012] Preferably, both the slider and the inner wall of the movable groove are designed in a rectangular shape, and when the slider rotates inside the movable groove, it can drive the support rod to rotate in a circular motion.

[0013] Preferably, the fixing block has a movable hole inside, and the inner wall of the movable hole is designed in a circular shape.

[0014] Preferably, a connecting rod is installed on one side of the outer wall of the support block, and the size of the movable hole is larger than the diameter of the connecting rod. The connecting rod is located inside the movable hole and can move inside the movable hole, which can ensure the transmission capability of the motor body to the connecting rod.

[0015] Preferably, limit blocks are installed on both outer walls of the connecting rod, and the two limit blocks are distributed on both sides of the support block. The limit blocks ensure the stability of the connecting rod inside the movable hole.

[0016] A method of using a film loading mechanism includes the following steps: Step 1: The operator places the film roll on the upper part of the pallet, and the pressure sensor detects the weight of the pallet to avoid damaging the equipment. The electric push rod pushes the film roll to move vertically until the film roll is aligned with the axis of the clamping head. Step 2: The side plate moves horizontally on the outside of the lead screw body, thereby adjusting the distance between the two clamping heads and clamping and fixing the film roll. Step 3: The motor body drives the connecting rod, rotating shaft, clamping head and film roll to rotate in a circular motion through the magnet body and connecting plate, thereby causing the film roll material to be actively released.

[0017] Compared with the prior art, the beneficial effects of the present invention are: by setting up a magnet body, a connecting rod and a support rod, the present invention achieves the effect of reducing the weight of the equipment, avoiding excessive load on the equipment, ensuring smooth operation of the equipment, and avoiding damage to the motor body.

[0022] A motor is provided on the outer wall of one end of the lead screw body 11. The motor can drive the lead screw body 11 to rotate in a circular motion, thereby driving the side plate 12 to move horizontally. The threaded openings on both sides of the lead screw body 11 are in opposite directions, thereby adjusting the distance between the two side plates 12 so that the distance between the side plates 12 conforms to the size of the film roll.

[0023] Each of the two rotating shafts 3 has a clamping head 31 installed on the outer wall of one side. The two clamping heads 31 can clamp and fix the film roll, ensuring that the film roll is in a stable position between the side plates 12.

[0024] Electric push rods 13 are installed on both sides of the lower outer wall of the upright plate 1. Pressure sensors 14 are installed on the upper outer wall of the electric push rods 13. A support plate 15 is installed on the upper outer wall of the pressure sensors 14. The inner wall of the support plate 15 is designed with an arc shape.

When the operator places the film roll on the upper end of the support plate 15, the pressure sensors 14 detect the weight of the support plate 15 to prevent damage to the equipment. The electric push rods 13 push the film roll to move vertically until the film roll is aligned with the axis of the clamping head 31. The side plate 12 moves horizontally outside the lead screw body 11, thereby adjusting the distance between the two clamping heads 31 so that the clamping heads 31 clamp and fix the film roll.

[0025] Example 2: A film loading mechanism includes a vertical plate 1, a motor body 2, and a rotating shaft 3. Screw bodies 11 are mounted on both outer walls of the vertical plate 1.

The partition plate 23 can separate the magnetic forces of the two magnet bodies 22. The mutual attraction between the magnet bodies 22 enables the motor body 2 to drive the support rod 35 to rotate.

[0027] Both the slider 33 and the inner wall of the movable groove 32 are designed in a rectangular shape. When the slider 33 rotates inside the movable groove 32, it can drive the support rod 35 to rotate in a circular motion.

[0028] The fixed block 24 has a movable hole 25 inside, and the inner wall of the movable hole 25 is designed in a circular shape.

[0029] A connecting rod 27 is installed on one side of the outer wall of the support block 26, and the size of the movable hole 25 is larger than the diameter of the connecting rod 27.
