Description

Technical Field

[0001] This utility model relates to the field of plastic film packaging technology, and in particular to a plastic film packaging machine with weighing function. Background Technology

[0002] A plastic film baling machine is a machine used to package plastic film, combining multiple rolls of plastic film together for packaging and protection. When using the machine, the appropriate number of plastic films are first weighed. After weighing, the film rolls are placed on a rotating turntable. Rotating the turntable wraps the film around the rolls, completing the packaging process.

[0003] Existing plastic film baling machines lack weighing capabilities and must be used in conjunction with a weighing device. This results in two steps for weighing and baling the plastic film, leading to low baling efficiency. Furthermore, the turntable is only connected to the bottom by a shaft and bearings, which lacks effective support around the shaft, making it prone to uneven force distribution and tilting, which can damage the bearings. Additionally, the turntable cannot be quickly disassembled and replaced. In existing plastic film baling machines, the film is torn by hand after baling, which neither guarantees a neat tear nor allows for proper handling, and requires excessive force.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-4 As shown, a plastic film baling machine with weighing function includes a weighing base 1, a column 2 on the weighing base 1, a controller 3 at the upper end of the column 2, a fixing rod 4 on the weighing base 1, a rotating structure 5 mounted on the weighing base 1, and a cutting structure 6 located on the weighing base 1 near the fixing rod 4. The bottom end of the weighing base 1 has a support leg 7, and a weight sensor is located inside the weighing base 1. The fixing rod 4 is fixedly mounted on the weighing base 1, and a support plate 8 is provided on the fixing rod 4.

[0021] When using the plastic film baling machine, the machine is stably positioned using the support legs 7. The packaging film rolls are fitted onto the fixed rod 4 and supported by the support plate 8. Multiple plastic film rolls are vertically placed onto the rotating structure 5. The weight sensor inside the weighing base 1 detects the weight, and the total weight of the plastic film rolls is displayed on the controller 3 at the top of the column 2, recording the weight. After recording the weight, the end of the packaging film on the fixed rod 4 is pulled and adhered to the plastic film roll. The rotating structure 5 is then rotated, causing the plastic film roll to rotate and wrap around it, thus completing the packaging process. After packaging, the rotating structure 5 is stopped, and the packaging film is cut using the cutting structure 6.

[0022] According to the above implementation scheme, the rotating structure 5 includes a fixed base 501, a bearing 502, a rotating rod 503, a hexagonal rod 504, a placement plate 505, and a hexagonal groove 506. The fixed base 501 is fixed on the weighing base 1. The bearing 502 is mounted on the fixed base 501. The rotating rod 503 is fixedly connected to the hexagonal rod 504, and the lower end of the rotating rod 503 is connected to the bearing 502. The hexagonal groove 506 is formed on the placement plate 505 and is engaged with the hexagonal rod 504. The placement plate 505 has a countersunk hole, and a connecting bolt is provided in the countersunk hole. The end of the connecting bolt is connected to the rotating rod 503. The placement plate 505 also has a screw hole. The rotating structure 5 further includes a support screw 507 and a ball bearing 508. The ball bearing 508 is located at the lower end of the support screw 507, and the support screw 507 is threadedly connected to the screw hole on the placement plate 505. The upper end of the support screw 507 has a hexagonal groove.

[0023] When using the rotating structure 5, the plastic film roll is placed on the placement plate 505. When wrapping the packaging film, the placement plate 505 closes the hexagonal rod 504 through the hexagonal groove 506, causing the rotating rod 503 to rotate. The rotating rod 503 rotates on the fixed seat 501 through the bearing 502, ensuring that the placement plate 505 can rotate smoothly. The plastic film roll rotates together with the placement plate 505 to perform the wrapping work of the packaging film.

[0024] During the rotation of the placement plate 505, the ball bearings 508 at the lower end of the support screw 507 move along the surface of the weighing base 1, providing effective support without affecting the normal rotation of the placement plate 505. When necessary, the position of the support screw 507 relative to the placement plate 505 can be rotated using tools to ensure that the ball bearings 508 are in contact with the weighing base 1, thus ensuring the support effect.

[0025] According to the above implementation scheme, the cutting structure 6 includes a vertical rod 601, a waist-shaped hole 602, a limiting groove 603, a movable block 604, a pin 605, and a blade 608. The waist-shaped hole 602 and the limiting groove 603 are formed on the vertical rod 601, and the vertical rod 601 is fixed to the weighing base 1. The movable block 604 is fixedly connected to the pin 605, and the pin 605 is located in the waist-shaped hole 602. The blade 608 is fixed to the movable block 604. The cutting structure 6 also includes a handle 606, an anti-slip sleeve 607, and a limiting rod 609. The handle 606 is fixed to the movable block 604, the anti-slip sleeve 607 is sleeved on the handle 606, and the limiting rod 609 is fixedly connected to the handle 606.

[0026] During the packaging process of plastic film rolls, the cutting parts, such as the movable block 604 and the pin 605, are located at the upper end of the vertical rod 601. The blade 608 points vertically downwards, while the handle 606 points vertically upwards. At the same time, the limiting rod 609 on the handle 606 is located in the limiting groove 603 at the upper end of the vertical rod 601. When cutting the packaging film, hold the handle 606 on the anti-slip sleeve 607 and move the movable block 604 upwards so that the limiting rod 609 moves out of the limiting groove 603. Then, rotate the movable block 604 through the pin 605 so that the blade 608 is in a horizontal state. Then, use the blade 608 to cut the packaging film. After cutting, move the movable block 604 to the highest point of the oblong hole 602 and rotate the movable block 604 so that the blade 608 and the handle 606 are in a vertical state. Use the limiting rod 609 to limit and store the movable block 604, the blade 608, and the handle 606.

[0027] It should be noted that the combination of the weighing base 1 and the rotating structure 5 enables the baling machine to have a weighing function, allowing weighing and baling to be completed in the same process, saving overall baling time. Through the rotating structure 5, the placement plate 505 is connected to the hexagonal rod 504, working in conjunction with the support screw 507 and ball bearings 508. This increases the rotational stability of the placement plate 505, ensuring the integrity of the bearing 502, while also allowing for quick disassembly and replacement of the placement plate 505, providing high flexibility. The support screw 507 can be used to... The height of the plate 505 is adjustable, making it highly adaptable. It adopts a cutting structure 6, which can quickly cut the film after packaging, improving the operation speed and ensuring the aesthetic appearance of the film tear. The movable block 604 is installed at the waist-shaped hole 602 via a pin 605, which can quickly raise and lower for cutting. A limit rod 609 is set on the handle 606, which works in conjunction with the limit groove 603. When not in use, the movable block 604 and the blade 608 can be stored vertically on the top of the vertical rod 601, increasing the safety of use.
