Description

Technical Field

[0001] The utility model particularly relates to a vacuum roller with adjustable suction force. Background Art

[0002] A vacuum roller, also known as a vacuum adsorption roller, is a widely used component in industrial production. It features a roller structure with an internal vacuum chamber and numerous tiny ventilation holes on its surface. When the vacuum chamber inside the roller is connected to an external vacuum source (such as a vacuum pump), negative pressure is generated within the chamber. Under this negative pressure, the vents on the roller surface attract objects that come into contact with it. Vacuum rollers primarily consist of a roller body, ventilation holes, a sealing structure, and a vacuum chamber. They are primarily used in the papermaking, printing, and packaging industries.

[0003] In actual operation, different substrates require different negative pressure suction forces. Most vacuum rollers control the air extraction rate by adjusting the power of the vacuum pump, thereby changing the suction force of the vacuum roller. However, this adjustment method requires experiments on the substrate to select the vacuum pump power suitable for the substrate to avoid damaging the substrate. This process is not efficient. Another method is to adjust the size of the vent hole, but the size of the vent hole is usually fixed, which cannot respond quickly to different substrates and is not very practical.

[0004] Therefore, it is necessary to invent a vacuum roller with adjustable suction to solve the above problems. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figure 1-3 The vacuum roller with adjustable suction shown in the figure includes support bases 2 mounted on both sides of a vacuum roller body 1. A drive assembly 3 is mounted on the upper portion of one support base 2, and a negative pressure assembly 4 is mounted on the other side. An adjustment roller assembly 5 is sleeved on the inner side of the vacuum roller body 1, and a vacuum tube 6 is also connected between the drive assembly 3.

[0028] Specifically, a plurality of negative pressure adsorption holes 11 are provided on the vacuum roller body 1;

[0029] Reference Figure 2 The driving assembly 3 includes a driving motor 31 and a driving shaft 32. The driving motor 31 is installed at one end of the driving shaft 32. The driving shaft 32 is covered with a fixing member 33 and is installed on the supporting base 2. One side of the driving shaft 32 is connected to a driving wheel 34. The driving wheel 34 is installed at both ends of the vacuum roller body 1.

[0030] Specifically, the negative pressure assembly 4 is installed on the other side support base 2;

[0031] Reference Figure 3 The adjusting roller assembly 5 includes an adjusting roller 51, which is provided with multiple adjusting holes 52 corresponding to the negative pressure adsorption holes 11. The adjusting roller 51 is attached to the inner side of the vacuum roller body 1. Rotating disks 53 are installed at both ends of the adjusting roller 51. The other end of the rotating disk 53 is installed on the driving wheel 34, and a mounting hole 54 is provided in the middle.

[0032] In this embodiment, the support base 2 is mounted on the corresponding equipment frame using fixing bolts 21 on both sides of the bottom. Ensure that the support base 2 is securely installed to provide stable support. For example, when installing it in a printing device, select a suitable location based on the device's layout and installation requirements, and tighten the fixing bolts 21 using appropriate tools to prevent the support base 2 from loosening during operation.

[0033] In this embodiment, a drive assembly 3 is mounted on top of a support base 2. First, a drive motor 31 is mounted on one end of a drive shaft 32. The drive shaft 32, with its fixings 33, is then mounted on the support base 2. Next, a drive wheel 34 is connected to one side of the drive shaft 32 and mounted on both ends of the vacuum roller body 1, thereby enabling the drive motor 31 to drive the vacuum roller body 1.

[0034] Specifically, a negative pressure assembly 4 is mounted on the other side of the support base 2. A negative pressure chamber 41 is mounted on the support base 2. Multiple negative pressure tubes 42 are then connected to one side of the negative pressure chamber 41. The other ends of the negative pressure tubes 42 are connected to external negative pressure equipment. Finally, a vacuum tube 6 is connected to the negative pressure chamber 41 at one end and positioned inside the vacuum roller body 1 at the other end to transmit negative pressure.

[0035] Specifically, the adjusting roller assembly 5 is installed inside the vacuum roller body 1. The rotating disks 53 at both ends of the adjusting roller 51 are mounted on the drive wheel 34. The adjusting roller 51 is attached to the inside of the vacuum roller body 1, ensuring that the adjusting holes 52 on the adjusting roller 51 correspond to the negative pressure adsorption holes 11 on the vacuum roller body 1. At the same time, the mounting hole 54 in the middle of the rotating disk 53 is connected to the outside of the drive shaft 32.

[0036] Specifically, the negative pressure component 4 includes a negative pressure chamber 41, which is installed on a supporting base 2 on one side. A plurality of negative pressure tubes 42 are connected to one side of the negative pressure chamber 41, and the negative pressure tubes 42 are connected to external negative pressure equipment. One end of the negative pressure chamber 41 is connected to a vacuum tube 6, which is arranged inside the vacuum roller body 1.

[0037] Specifically, both ends of the vacuum roller body 1 are fixed on the driving wheel 34 , the rotating disk 53 is mounted on the driving wheel 34 , and the vacuum roller body 1 and the regulating roller 51 can rotate independently.

[0038] Specifically, the size of the adjustment holes 52 is consistent with the size and number of the negative pressure adsorption holes 11 , and the mounting holes 54 provided on the rotating disks 53 installed at both ends of the adjustment roller 51 are connected to the outside of the driving shaft 32 .

[0039] Specifically, fixing bolts 21 are installed on both sides of the bottom of the support base 2.

[0040] In this embodiment, the suction force can be adjusted by rotating the adjustment roller 51 before or during operation. Because both ends of the adjustment roller 51 are mounted on a rotating disk 53, which is mounted on the drive wheel 34, the adjustment roller 51 is rotated by rotating the rotating disk 53 using an external adjustment device (such as a manual rotating lever or an electric adjustment device). As the adjustment roller 51 rotates, the overlap area between the adjustment hole 52 and the negative pressure suction hole 11 changes. To increase the suction force, the adjustment roller 51 can be rotated to a position that maximizes the overlap area between the adjustment hole 52 and the negative pressure suction hole 11. To decrease the suction force, the adjustment roller 51 can be rotated to a position that minimizes the overlap area.

[0041] In this embodiment, the drive motor 31 is activated, driving the drive shaft 32 to rotate. The drive shaft 32, in turn, drives the vacuum roller body 1 via the drive wheel 34. As the vacuum roller body 1 rotates, an external negative pressure device provides negative pressure to the negative pressure chamber 41 via the negative pressure tube 42. The negative pressure chamber 41 transmits the negative pressure to the interior of the vacuum roller body 1 via the vacuum tube 6, generating suction in the negative pressure adsorption holes 11. Because the vacuum roller body 1 and the adjustment roller 51 can rotate independently, the adjustment roller 51 can rotate as needed to adjust the suction force during the rotation of the vacuum roller body 1.

[0042] In this embodiment, the suction force is adjusted by adjusting the overlapping area between the roller 51 and the holes in the vacuum roller body 1, which enables very precise suction force control. For example, when handling thin electronic components, the suction force can be precisely adjusted to a level that is just enough to hold the components without damaging them.

[0043] Specifically, in various industrial production scenarios, materials of varying weights, shapes, and materials need to be adsorbed. This suction adjustment method can be easily adjusted based on the characteristics of the material. For example, in the packaging industry, both lighter plastic films and heavier cardboard can be effectively adsorbed and conveyed by adjusting the suction force.

[0044] In this embodiment, thanks to the stable structure of the drive assembly 3, the drive motor 31 is able to stably drive the vacuum roller body 1 to rotate. This maintains a constant rotational speed over extended periods of operation, eliminating speed fluctuations caused by unstable power transmission. This is crucial for ensuring production process stability and product quality. For example, during high-speed printing, a stable vacuum roller rotational speed ensures uniform paper suction and transfer, preventing problems such as misaligned printing.

[0045] Specifically, the structural design of the negative pressure assembly 4 efficiently transfers the negative pressure provided by the external negative pressure device to the interior of the vacuum roller body 1. This enables the negative pressure adsorption holes 11 to quickly generate sufficient suction, improving the operating efficiency of the equipment. On some automated production lines, rapid and effective negative pressure adsorption can speed up material transfer, thereby improving the production efficiency of the entire production line.

[0046] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
