Description

TECHNICAL FIELD

[0001] The utility model belongs to laser drilling equipment technical field, especially a kind of paper supporting roller mechanism for cigarette tipping paper punching. BACKGROUND

[0002] In the field of laser drilling, especially the punching of cigarette tipping paper, designing a paper supporting roller mechanism is crucial. Here are the key factors to consider when designing a paper supporting roller mechanism.

[0003] First, in terms of material selection, since laser drilling generates high temperatures, the paper supporting roller needs to be made of high-temperature-resistant materials such as stainless steel or ceramics. The paper supporting roller frequently comes into contact with paper, so the material needs to have high wear resistance to extend its service life. Second, a cooling system needs to be designed to ensure that the paper supporting roller operates at the appropriate temperature and prevents overheating of the tipping paper.

[0004] Current paper supporting roller mechanisms generally have an external air cooling system that directly blows air onto the tipping paper and the paper supporting roller. This directly cools the tipping paper and the paper supporting roller. Since the tipping paper needs to maintain a certain temperature during punching, the tipping paper is more stable in a constant temperature environment. Therefore, this cooling method does not have a stable cooling effect, and temperature changes can cause deformation or shrinkage during punching, further limiting the quality and production efficiency of laser drilling. SUMMARY

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] Example

[0034] like Figures 1-11 As shown, a paper-supporting roller mechanism for perforating cigarette tipping paper includes a support base 1, a roller box 2, and a fixed box 3. Two fixed boxes 3 are arranged at a fixed distance from the upper end of the support base 1. The roller box 2 is arranged on the upper end of the support base 1 and is closely attached to the inner wall of the two fixed boxes 3. Several spindles 5 are fixed between the two fixed boxes 3. Paper-supporting rollers 4 are rotatably mounted on the spindles 5. The two ends of the paper-supporting rollers 4 pass through the fixed boxes 3, and the middle of the paper-supporting rollers 4 passes through the roller box 2. The fixed box 3 is provided with a pipe 34 for introducing a cooling medium.

[0035] During operation, the feed paper 7 is placed on the feed roller 4 inside the roller box 2. The roller box 2 provides dust protection during laser drilling. Furthermore, the two ends of the feed roller 4 pass through the fixed box 3, while the middle of the feed roller 4 passes through the roller box 2. Cooling medium is introduced into the fixed box 3 to cool the feed roller 4, achieving temperature control during laser drilling. This structure places the working area of ​​the feed roller 4 inside the roller box 2 and the cooling area inside the fixed box 3. This ensures that the feed paper 7 is always drilled under a constant temperature, reducing deformation or shrinkage caused by temperature changes. This further improves the quality and production efficiency of laser drilling, guaranteeing the cooling efficiency of the feed roller 4 while preventing the cooling medium from directly affecting the drilling quality of the feed paper 7.

[0036] like Figure 3 and Figure 11 As shown, the paper support roller 4 further includes a cooling chamber 41 inside, and through holes 42 communicating with the cooling chamber 41 are provided at both ends of the paper support roller 4. In this design, the cooling medium enters the fixed box 3 from one side, then enters the interior of the paper support roller 4 to cool it, and then reaches the fixed box 3 on the other side, achieving a heat exchange effect. This structure improves the cooling efficiency of the paper support roller 4, ensuring that it can be controlled at a constant temperature during laser drilling, thus guaranteeing the quality of laser drilling. The cooling medium directly cools the paper support roller 4 but does not act on the splicing paper 7, avoiding large temperature changes in the splicing paper 7 and ensuring drilling quality.

[0037] like Figures 1-10As shown, both the fixed box 3 and the roller box 2 are set in an arc shape, and the paper rollers 4 are arranged in an arc shape to facilitate the tensioning of the paper 7 for laser punching.

[0038] like Figures 1-11 As shown, a cooling groove 35 is further provided on one side of the fixed box 3. The cooling groove 35 is arc-shaped, and a fixing groove 33 is provided on the inner wall of the cooling groove 35. The end of the spindle 5 is fixed in the fixing groove 33, and both ends of the paper support roller 4 are set in the cooling groove 35. The pipe 34 is connected to the cooling groove 35. Cold air is introduced from the pipe 34 into the cooling groove 35 to directly cool the paper support roller 4. At the same time, the cold air enters from the through hole 42 on the side wall of the paper support roller 4 to cool the inside of the paper support roller 4. The combination of internal and external cooling improves the cooling efficiency.

[0039] like Figures 1-11 As shown, furthermore, several clearance holes 25 are provided through both sides of the roller box 2, and the paper support roller 4 passes through the clearance holes 25. With this design, the connection position between the paper support roller 4 and the spindle 5 is located inside the fixed box 3, thus providing protection. The spindle 5 is equipped with bearings and seals 6, which support the rotation of the paper support roller 4. Since the cooling tank 35 is filled with cooling gas and has a certain pressure, dust generated during drilling will not seep into the fixed box 3 through the clearance holes 25, ensuring that the bearings and seals 6 are dust-free, ensuring the smooth rotation of the paper support roller 4, and ensuring the quality of laser drilling.

[0040] Furthermore, the upper end of the paper support roller 4 is evenly distributed with several working holes 21 for the laser to pass through. In use, the paper support roller mechanism of this invention is installed on the bottom side of the laser drilling equipment, with the laser head directly facing the working holes 21 for drilling.

[0041] In this utility model, an arc-shaped mounting plate 12 is provided at the upper end of the support base 1, the fixing box 3 and the roller box 2 are mounted on the mounting plate 12, and U-shaped limiting seats 13 are symmetrically arranged on both sides of the mounting plate 12. The roller box 2 is set close to the inner wall of the limiting seat 13 to realize the limiting installation of the roller box 2.

[0042] Furthermore, a positioning ramp 15 is provided on one side of the limiting seat 13, and conical positioning blocks 36 are provided at both ends of the fixed box 3. The positioning blocks 36 are fitted on the positioning ramp 15 to achieve the limiting installation of the fixed box 3.

[0043] Furthermore, paper-passing holes 22 are provided on both sides of the roller box 2 for receiving paper 7 to pass through, and connecting blocks 23 are respectively extended at both ends of the roller box 2, with the connecting blocks 23 closely attached to the upper surface of the limiting seat 13.

[0044] Furthermore, the roller box 2 has several through-holes 27, and the fixed box 3 has several corresponding connecting holes 32. Two connecting holes 32 are located on the positioning block 36, and the other connecting hole 32 is located on the connector 31, which is positioned at the upper part of the middle of the fixed box 3. When the fixed box 3 and the roller box 2 are in close contact, aligning the connecting holes 27 and 32, the roller box 2 and the fixed box 3 are fixed with bolts. An annular sealing groove 26 is provided on the outer side of several arc-shaped clearance holes 25, and a sealing strip is placed in the sealing groove 26. The fixed box 3 presses the sealing strip to achieve a sealed connection.

[0045] Furthermore, the connecting block 23 is provided with several connecting holes 24, and the limiting seat 13 is provided with several connecting holes 14 corresponding to the connecting holes 24. When the connecting holes 24 and the connecting holes 14 are aligned, the roller box 2 and the support seat 1 are fixed with bolts.

[0046] like Figures 1-6 As shown, in this utility model, the support base 1 is triangular in shape and hollow inside. Several mounting holes 11 are annularly formed on the support base 1. During installation, the support base 1 is mounted on the mounting panel of the laser drilling equipment through the mounting holes 11. Several diagonal ribs 16 are provided on the mounting base to strengthen the entire support base 1.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
