Description

Technical Field

[0001] This utility model belongs to the field of cigarette production technology, specifically relating to a cork paper gluing device. Background Technology

[0002] Gluing the tipping paper is a crucial functional device on the splicing machine. The uniformity and stability of the glue application process not only affect the machine's operational performance but also directly impact the quality of the tipping paper splicing, making it one of the most critical components related to product quality. Existing glue application devices employ a glue tank supply method. A pair of opposing rotating cylindrical glue rollers form a glue layer through extrusion. One roller, located on the lower left, has a concave surface of a certain depth and width and is immersed in a glue tank filled with glue. The other roller, located on the upper right, has a flat surface. When the two rollers contact and rotate, under applied pressure, excess glue is squeezed out, forming a glue layer of a certain thickness and width on the surface of the upper roller, which is then applied to the tipping paper. Therefore, the thickness, uniformity, and distribution of the glue layer depend not only on the precision of the glue rollers and roller shafts themselves but also significantly on the magnitude and stability of the pressure between the rollers.

[0018] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0019] This utility model embodiment provides a device for applying glue to cork paper. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 It mainly includes a glue cylinder 1, a glue control roller 2, a glue feeding roller 3, a curved arm 4, and a drive assembly 5.

[0020] In this embodiment, the water-twig coating device includes a coating cylinder 1, a control roller 2, a coating roller 3, a curved arm 4, and a drive assembly 5. The coating cylinder 1 stores adhesive liquid. The control roller 2 is arranged inside the coating cylinder 1 and contacts the adhesive liquid in the coating cylinder 1. The coating roller 3 is arranged around the control roller 2. The curved arm 4 is located at the bottom of the coating cylinder 1 and abuts against the bottom of the coating cylinder 1. The drive assembly 5 is arranged around the curved arm 4 and is connected to the curved arm 4. The drive assembly 5 drives the curved arm 4 to rise or fall, thereby driving the control roller 2 and the coating cylinder 1 to rise or fall. During the rising or falling of the coating cylinder 1, the distance between the control roller 2 and the coating roller 3 changes, thereby adjusting the pressure and stability between the coating roller 3 and the control roller 2, thus ensuring that the coating thickness, uniformity, and adhesive area distribution meet production requirements and guarantee the quality of cigarette production.

[0021] It is foreseeable that when the control roller 2 rotates, the adhesive adhering to the control roller 2 will be thrown off the control roller 2 under the action of centrifugal force. In order to avoid the adhesive adhering to the drive assembly 5 and affecting the drive assembly 5, in one embodiment, a baffle 6 is provided between the glue cylinder 1 and the drive assembly 5. The baffle 6 is used to separate the glue cylinder 1 from the drive assembly 5. One end of the bent arm 4 is rotatably connected to the baffle 6, and the other end of the bent arm 4 is connected to the drive assembly 5. The drive assembly 5 drives the other end of the bent arm 4 to rise or fall, so that the other end of the bent arm 4 rotates with the first end of the bent arm 4 as the rotation center, thereby adjusting the height of the glue cylinder 1.

[0022] In one possible implementation, the drive assembly 5 includes a rotary cylinder 51 and a connecting rod 52 disposed on the side of the baffle 6 away from the glue cylinder 1, and a rotating shaft 53 and a lifting rod 54 disposed on the side of the baffle 6 near the glue cylinder 1. The rotary cylinder 51 is connected to the first end of the connecting rod 52, the second end of the connecting rod 52 is connected to the first end of the rotating shaft 53, the second end of the rotating shaft 53 is connected to the first end of the lifting rod 54, and the second end of the lifting rod 54 is connected to the other end of the bent arm 4. The rotary cylinder 51 drives the connecting rod 52 to rotate, which in turn drives the rotating shaft 53 to rotate, which in turn drives the lifting rod 54 to rotate. When the lifting rod 54 rotates, it raises or lowers the other end of the bent arm 4, thereby adjusting the height of the glue cylinder 1. The direction in which the rotary cylinder 51 raises the glue cylinder 1 is... Figure 3 The direction indicated by the middle arrow.

[0023] Preferably, the connecting rod 52 includes a connecting part 521 and a rotating part 522. The rotating part 522 is provided with an installation space, and the rotating shaft 53 is inserted into the installation space. The connecting part 521 is connected to the rotary cylinder 51. The rotary cylinder 51 pushes the connecting part 521 to rotate around the rotating part 522, thereby driving the rotating shaft 53 to rotate.

[0024] Furthermore, the drive assembly 5 also includes a rotating shaft seat 55 disposed on the side of the baffle 6 near the glue cylinder 1. The rotating shaft seat 55 is detachably connected to the baffle 6. The rotating shaft seat 55 has a rotation space, and the rotating shaft 53 is inserted into the rotating shaft 53 space. By fixing the rotating shaft 53 in the rotating shaft seat 55, the glue adhering to the glue control roller 2 is prevented from being thrown onto the rotating shaft 53, thus ensuring the stability of the drive assembly 5 in raising or lowering the glue cylinder 1.

[0025] Furthermore, a roller 7 is provided at one end of the lifting rod 54 near the curved arm 4. The roller 7 is rotatably connected to the lifting rod 54, and the surface of the roller 7 abuts against the curved arm 4. By setting the roller 7, the friction between the lifting rod 54 and the curved arm 4 is reduced during the process of the lifting rod 54 driving the curved arm 4 to rise or fall, so as to reduce the wear of the device. In addition, the setting of the roller 7 also ensures that the roller 7 of the lifting rod 54 always abuts against the curved arm 4, eliminating the change in clamping force caused by the position change caused by the shaking of the water tipping paper gluing device during movement due to manufacturing errors.

[0026] Preferably, the height of the rotation center of roller 7 is lower than the height of the rotation center of shaft 53, and the height direction is... Figure 3 The X-axis direction in the diagram.

[0027] In one possible implementation, the lifting rod 54 is also provided with a mounting groove 541, and a threaded hole is provided in the mounting groove 541. The rotating shaft 53 is inserted into the mounting groove 541. The cork paper gluing device also includes a locking bolt, which is screwed into the threaded hole to lock the rotating shaft 53.

[0028] In one possible implementation, the drive assembly 5 further includes a pressure regulating valve 57, a pressure gauge 58, and a manual valve 59. The pressure regulating valve 57 is connected to the pressure gauge 58, and the pressure gauge 58 is also connected to the manual valve 59. The manual valve 59 is connected to the rotary cylinder 51. The air source is connected to the pressure regulating valve 57, and the compressed air pressure is adjusted by the pressure regulating valve 57 to obtain the optimal clamping force of the rubber roller.

[0029] Furthermore, due to manufacturing errors in components such as the control roller 2 and the top roller 3, these errors cause periodic fluctuations in the piston within the rotary cylinder 51 during rotation. The drive assembly 5 also includes a one-way valve 56, which is positioned between the pressure regulating valve 57 and the manual valve 59. The manual valve 59 is connected to the control valve 59, which is mounted on the control panel of the assembly machine's electrical control box (with a spare switch hole). The roller's rise or fall is controlled by the manual valve 59. The rotary cylinder 51 is an AVENTICS compact single-acting cylinder. When the roller is raised, compressed air pushes out the piston; when it falls, a spring within the rotary cylinder 51 resets it. The pressure regulating valve 57 is adjusted to obtain the optimal clamping force according to production needs. The pressure gauge 58 displays and records the optimal thrust value for operator observation, recording, and reference. By using the one-way valve 56 to isolate the air source and utilizing the compressibility of gas to buffer and absorb piston fluctuations, the cylinder's thrust remains constant.
