Description

Technical Field

[0001] This invention relates to the field of plastic film technology, and in particular to a compensation device for the quality and dimensional deviation of paper tubes and its method of use. Background Technology

[0002] During production, the plastic film machine needs to wind the formed plastic film onto paper tubes to produce the finished product. This ensures that the plastic film is long enough and not messy, and only the amount needed can be taken out, which is very convenient. In order to improve production efficiency, multiple paper tubes are wound at the same time.

[0003] However, existing plastic film winding machines have gaps between paper tubes, which can cause film misalignment during winding and affect the quality of the finished product. Excessive misalignment can lead to waste of plastic film, requiring manual pushing of the paper tubes for positioning. In addition, the quality of the paper tubes varies, which can also affect the weight of the finished product. Therefore, a compensation device for paper tube quality and dimensional deviation and its usage method are proposed. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a compensation device for the quality and size deviation of paper tubes, so as to improve the working efficiency and yield of plastic film winding production, reduce production costs, reduce manual labor, and thus improve the practicality of the device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a compensation device for the quality and dimensional deviation of paper tubes, comprising a first mounting base and a second mounting base, the second mounting base being fixedly installed at the front end of the first mounting base, a first mounting bracket being fixedly installed on the top of the first mounting base, a main tray and a weighing tray being fixedly installed on the top of the first mounting bracket, the weighing tray being located at the front end of the main tray, a weighing component being fixedly installed on the bottom of the main tray near the weighing tray, a slider being provided on the top of the second mounting base, a compensation platform being fixedly installed on the slider, a first limiting component, a push plate and a second limiting component being provided on the compensation platform, a driving component being fixedly installed at the bottom of the compensation platform, and the driving component being pulsatorically connected to the push plate.

[0006] Preferably, a second mounting bracket is fixedly installed on the top of the main tray, a cylinder is fixedly installed on the second mounting bracket, a separation baffle is fixedly installed at the output end of the cylinder, the separation baffle is located above the connection between the main tray and the weighing tray, and a limit cylinder assembly is fixedly installed on the main tray, the limit cylinder assembly is located on the side of the separation baffle closer to the main tray.

[0007] Preferably, a transverse component is fixedly mounted on the top of the second mounting base, and the output end of the transverse component is fixedly connected to the slider.

[0008] Preferably, the second mounting base is provided with a guide rail at the top, and engagement blocks are fixedly installed on both sides of the bottom of the slider. The guide rail and the engagement blocks engage with each other, and the slider slides on the top of the guide rail.

[0009] Preferably, the main tray is inclined, and the angle between it and the horizontal direction is 10-30°.

[0010] Preferably, the side where the main pallet connects to the weighing pallet is close to the horizontal plane.

[0011] The present invention also provides a compensation device for paper tube quality and dimensional deviation and a method for using the same, which employs the above-mentioned compensation device for paper tube quality and dimensional deviation and includes the following steps:

[0012] S1. Adjust the angle of the main tray and adjust the angle between the main tray and the horizontal plane to 10-30°.

[0013] S2. Loading begins from one side above the main pallet, placing paper tubes side-by-side on the main pallet. The separation baffle and the limiting cylinder assembly block the paper tubes. The limiting cylinder assembly is activated, releasing the paper tubes from contact with the separation baffle and then resetting. The cylinder is then activated, causing the piston rod on the cylinder to retract, lifting the separation baffle. The paper tubes roll to the lower side of the main pallet and fall onto the weighing pallet. The weighing assembly weighs the paper tubes on the weighing pallet. When a set of paper tubes reaches the weighing pallet, the cylinder resets, continuing to limit the paper tubes on the main pallet.

[0014] S3. After the paper tube on the weighing tray is weighed, the paper tube is recorded to control the amount of plastic film to be wound later. The transverse component is activated, and the transverse component drives the slider to move towards the bottom side of the weighing tray. When the compensation platform is directly below the weighing tray, the compensation platform reaches the designated position.

[0015] S4. Move the paper tube on the weighing tray to the compensation platform and place it between the first limiting components. The first limiting components limit the paper tube. Then, start the driving component. The driving component drives the push plate to move upward and then to the side of the second limiting component. The push plate and the second limiting component cooperate to press the paper tube together and eliminate the gap between the paper tubes.

[0016] S5. After the paper tube is tightened, remove the tightened paper tube and wind the plastic film. Move it to the winding station of the film production unit for quality compensation. The paper tube compensation process is then complete.

[0017] Preferably, the following steps are also included:

[0018] S6. The driving component drives the push plate to reset, and the transverse component drives the slider to reset, and production continues by repeating the above steps.

[0019] The working principle of the paper tube quality and size deviation compensation device of the present invention is as follows: During production, the paper tube is first placed on the main tray, and the separation baffle and the limiting cylinder group block it. After the limiting cylinder group is removed, the paper tube is released and returns to its original position after contacting the separation baffle. After the separation baffle is removed, the paper tube rolls onto the weighing tray under the action of gravity. The weighing component weighs the paper tube and records its weight. When winding the plastic film, the weight of the finished product is controlled to be similar. The paper tube with the recorded weight is moved to the compensation platform. The first limiting component limits the paper tube in the front and back direction to prevent the paper tube from moving. The push plate moves upward and then to the side of the second limiting component, pushing the paper tube and pressing it between the push plate and the second limiting component to eliminate the gap between the paper tubes. This ensures that the paper tubes are tightly connected during production, thereby improving the working efficiency and yield of winding the plastic film.

[0020] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0021] 1. The paper tubes are weighed and recorded by the main tray and weighing tray set on the first mounting base. The weight of the paper tubes is controlled by the weight of the plastic film to ensure that the finished product weight is similar. Then the paper tubes are transported to the compensation platform to compensate for the gap between the paper tubes and tighten them before they are sent to be wound with plastic film. This can effectively improve work efficiency, reduce the number of defective products caused by excessive gaps between paper tubes, thereby reducing the cost of plastic film winding and improving the practicality of the device.

[0022] 2. By setting the main tray to an inclined position, the paper tubes on the main tray can move towards the weighing platform side under the action of gravity. In conjunction with the separation baffle, it can realize continuous production with quality compensation of paper tubes, improve work efficiency, and further enhance the practicality of the device.

[0034] It should be noted that the main tray 4 is tilted, and the front end of the main tray 4 forms an angle of 15° with the horizontal plane.

[0035] How to use:

[0036] S1. First, adjust the angle of the main tray 4 by loosening the bolts on the first mounting bracket 3, rotating the main tray 4, and adjusting the included angle between the main tray 4 and the first mounting base 1 to 15°.

[0037] S2. Loading begins from one side above the main pallet 4. Paper tubes are placed side-by-side on the main pallet 4. The separating baffle 7 and the limiting cylinder assembly 19 block the paper tubes. The limiting cylinder assembly 19 is activated, releasing the paper tubes and then resetting. The paper tubes and the separating baffle 7 are positioned against one side of the main pallet 4.
