Description

TECHNICAL FIELD

[0001] The present application relates to an improved packaging device, in particular to a paper towel feeding mechanism of a packaging device. BACKGROUND

[0002] The paper towel is packaged by film, square box or cylinder. The film packaging, square box packaging and the square shape of the paper towel are similar to the traditional packaging method, which is not suitable for on-board use due to the large area occupied. The paper towel packaged by cylinder can be placed vertically, which occupies a small area and is particularly suitable for on-board use. The cylinder packaging is more difficult than the film packaging and the square box packaging. The paper towel is curled into a cylindrical shape when the paper towel is stacked to a certain thickness, so that the paper towel can be packed into the cylinder. Due to the difficulty of packing the paper towel into the cylinder, the current cylinder packaging is still packaged manually, which has the problems of low efficiency and high cost. SUMMARY

[0003] In view of the technical problems in the background art, the technical problems solved by the present application aim to provide a paper towel feeding mechanism of a packaging device, which realizes automatic production by manual feeding of the bag body.

[0004] To solve the above technical problems, the present application adopts the following technical scheme: the paper towel feeding mechanism of the packaging device, characterized by comprising

[0005] The cylinder forming part comprises

[0006] The material supporting part,

[0007] The limiting part is arranged above the material supporting part,

[0008] The cylinder forming part is arranged above the material supporting part, and the cylinder forming part is arranged above the material supporting part.

[0009] The pushing part comprises a longitudinally moving pushing part, and the pushing part is arranged above the material supporting part, and the pushing part is arranged above the material supporting part.

[0010] Before the paper towel is fed, the cylinder forming part moves upward, pushing the paper towel on the material supporting part upward, and when the middle position of the paper towel is blocked by the limiting part, the cylinder forming part still continues to move upward, the paper towel is pressed into the cylinder cavity, the two sides of the paper towel are close to each other, and the paper towel is roughly in a cylindrical shape. Then, the pushing part moves to the feeding station, pushing the paper towel in the cylinder into the cylinder box body in the feeding station, realizing automatic feeding of the cylinder packaging.

[0011] Preferably, the limiting component is provided with an inlet sleeve, which is located at the feeding station and has an inlet channel. The inlet inner diameter of the inlet channel is larger than the outlet inner diameter of the inlet channel, and the outlet inner diameter of the inlet channel is not larger than the inner diameter of the packaging tube. The inlet sleeve assists in feeding, allowing the rolled paper towels to smoothly enter the cylindrical box body along the inlet channel.

[0012] Preferably, the limiting member is a thin, vertically arranged limiting plate with a rounded bottom surface. A thin limiting plate occupies less space and therefore does not occupy the space for forming the tissue roll. Simultaneously, the rounded bottom surface reduces stress between the tissue roll and the tissue, preventing damage during roll forming and feeding.

[0013] Preferably, the material support is a narrow strip, and the inlet end of the material support is connected to the outlet end of the feeding component. The paper towel is fed onto the material support by the feeding component. The narrow width of the material support corresponds to the narrow width of the notch, which avoids the paper towel being pressed into the notch when forming the roll.

[0014] Preferably, the feeding component includes a tray, a transmission chain, and push rods. The tray has a channel for the push rods to move. The push rods are vertically mounted on the transmission chain, and there are several push rods evenly distributed on the transmission chain. The paper towel is placed between two push rods. The transmission chain drives the push rods to move, and the push rods push the paper towel towards the forming station until the paper towel enters the forming station and is placed on the tray.

[0015] Preferably, the pushing component includes a longitudinally arranged linear guide rail, which is mounted on the frame, and the pushing component is connected to a first driving component that drives it to move longitudinally on the linear guide rail.

[0016] Preferably, the cylindrical component is slidably mounted on a vertically arranged guide rail, which is mounted on a frame, and the cylindrical component is connected to a second driving component that drives it to move up and down on the guide rail.

[0017] Preferably, the material support is provided with side baffles on both sides, the spacing between the side baffles matching the material, and the side baffles and the material support forming a material cavity. This ensures precise positioning of the paper towels, improves the quality of the rolled product, and guarantees qualified feeding. Attached Figure Description

[0023] The following describes the embodiments and related details and working principles of the present invention with reference to the accompanying drawings. In the figures, the X-axis is horizontal, the Y-axis is vertical, and the Z-axis is vertical. The paper towel feeding mechanism of this packaging equipment includes a tube forming component and a pushing component. The tube forming component includes a material support component 5, a limiting component 3, and a vertically lifting tube forming component 4. The limiting component 3 is located above the material support component 5. Side baffles 17 are provided on both sides of the material support component. The distance between the side baffles matches the material, and the side baffles and the material support component form a material cavity, which can accurately position the paper towel and improve the quality of tube forming. The tube forming component 4 has a tube forming cavity 8. The cross-section of the tube forming cavity is arc-shaped. The opening of the tube forming cavity faces the upward limiting component 3. The tube forming component has a notch 9 for the material support component to pass through. When the tube forming component moves upward, the material support component 5 passes through the notch, so as not to affect the lifting of the tube forming component 4. The tube-forming cavity in the figure is roughly semi-cylindrical, meaning the cross-section is semi-circular. This provides a large opening, which facilitates the entry of the paper towel 7 into the tube-forming cavity 8 while also allowing the paper towel to form a tube shape. The pushing component includes a longitudinally moving pushing component 2, which is positioned above the supporting component 5. The pushing component has a notch 21 for the limiting component to pass through. When the pushing component moves forward, the limiting component 3 enters the notch 21, thus not affecting the movement of the pushing component 2. The tissue paper 7 enters the material chamber, the forming component 4 moves upward, pushing the tissue paper 7 on the material support component upward. It is best to set the limiting component in the middle position of the forming component, so that the middle position of the tissue paper is blocked by the limiting component 3. As the forming component moves upward, the two sides of the tissue paper are forced to move towards each other. The tissue paper is formed into a tube shape with the limiting component 3 as the center and is pressed into the forming cavity 8. Then, the pushing component 2 moves towards the feeding station 12, pushing the tube of tissue paper into the cylindrical box body of the feeding station, realizing automatic feeding of cylindrical packaging. After the feeding is completed, the forming component 4 moves down to reset and the pushing component 2 moves back to reset until the next material enters the material chamber.

[0024] The limiting component 3 is equipped with an inlet sleeve 6, which is located at the feeding station 12. The inlet sleeve is close to the cylindrical box body and has an inlet channel. The rolled paper towels first pass through the inlet sleeve before entering the cylindrical box body. The inlet sleeve plays an auxiliary guiding role, allowing the rolled paper towels to smoothly enter the cylindrical box body along the inlet channel, making the feeding more stable. The inner diameter of the inlet 19 of the inlet channel is larger than the inner diameter of the outlet 20 of the inlet channel, and the inner diameter of the outlet of the inlet channel is not larger than the inner diameter of the packaging tube. It is better if the inner diameter of the outlet of the inlet channel is slightly smaller than the inner diameter of the packaging tube, which is more conducive to the feeding of paper towels. The inner diameter of the inlet of the inlet channel is larger than the inner diameter of the outlet of the inlet channel, which facilitates the entry of the rolled paper towels into the inlet channel. The compression of the inlet channel makes the outer diameter of the rolled paper towels meet the feeding requirements.

[0025] See attached Figure 5 The limiting member 3 is a thin, vertically arranged limiting plate with a bottom surface of arc surface 18. The outer diameter of this arc surface can be slightly larger than the thickness of the limiting member. The thin limiting plate occupies little space and therefore does not occupy the position for forming the paper towel roll. This allows the two ends of the paper towel roll to be closer together. At the same time, the arc surface is smooth and will not scratch the paper towel. Moreover, when the limiting member 3 is pressed with the paper towel, the stress between the arc surface 18 and the paper towel is small, which can prevent damage to the paper towel during roll forming and feeding, thus ensuring the quality of the paper towel. The material support member 5 is a narrow strip and can be one or two. The narrow width of the material support member corresponds to the narrow width of the notch 9, preventing the paper towel from being squeezed into the notch. If the notch is too wide, the paper towel may be squeezed into the notch during roll forming, resulting in feeding failure. The feeding end of the material support 5 is connected to the discharging end of the feeding component, and the paper towel is fed onto the material support by the feeding component. The feeding component includes a support plate, a transmission chain 14, and push rods 13. The support plate has a channel for the push rods to move. The push rods are vertically mounted on the transmission chain. Several push rods 13 are provided and evenly distributed on the transmission chain 14. The paper towel is placed on the support plate between two push rods. The transmission chain 14 drives the push rods to move, and the push rods 13 push the paper towels towards the forming station 11 until the paper towels enter the forming station and are placed on the material support 5. The pushing component includes a longitudinally arranged linear guide rail 15, which is mounted on the frame 1. The pushing component 2 is connected to a first driving component that drives it to move longitudinally on the linear guide rail. The cylindrical component 4 is slidably mounted on a vertically arranged guide rail 16, which is mounted on the frame 1. The cylindrical component is connected to a second driving component that drives it to move up and down on the guide rail. Both the linear guide rail and the guide rail are for stable movement. The first and second driving components can be cylinders, lead screw mechanisms, cam mechanisms, or linkage mechanisms, etc.
