Description

Technical Field

[0001] The utility model relates to the technical field of positioning and guiding devices, in particular to a disk paper guide with a positioning and air suction function. Background Art

[0002] The core responsibility of the disk paper guide in the YJ17 cigarette making machine is to ensure that the disk paper accurately enters the cigarette gun component of the rolling and forming system. To achieve this goal, the center line of the disk paper needs to be strictly aligned with the center line of the rolling and forming channel, and the two should be in the same plane, which is also parallel to the front plane of the fuselage.

[0003] During actual operation, when the ZJ17 cigarette making machine accesses the disk paper, the disk paper is prone to shaking, resulting in the edge of the disk paper being difficult to smoothly enter the limit plate of the disk paper guide or easily slipping out of the limit plate of the disk paper guide, which will cause the edge of the disk paper to stick to the outer surface of the limit plate, resulting in the center line of the disk paper not being aligned with the center line of the rolling and forming channel, and further causing the edge of the disk paper to warp. The quality inspection standards for cigarettes have strict requirements on the evenness, firmness, and neatness of the cigarette lap. Any warping phenomenon is not allowed. If the surface of the cigarette lap is significantly warped and the width of the lap without glue exceeds 0.5 mm and the length exceeds 1 / 2 of the cigarette, such a product will be judged as a Class C non-conforming product. This phenomenon that the cigarette lap edge exceeds the quality standard not only leads to an increase in the non-conforming product rate but also increases the amount of waste cigarettes and production consumption.

[0004] Therefore, to address this problem, the operator has to frequently intervene manually to ensure the correct introduction of the disk paper. In addition, after splicing the disk paper each time, the operator also needs to carefully check the height positions of the left and right edges of the disk paper to prevent the risk of the disk paper slipping out of the limit plate of the disk paper guide. However, this method not only has low work efficiency, but during continuous equipment operation, the disk paper is still prone to slipping out of the disk paper guide, thereby producing non-conforming cigarettes. Summary of the Utility Model

[0024] AsFigures 1 to 6 As shown, the utility model provides a paper guide for web paper with a positioning and air suction function.

[0025] It includes a U-shaped bracket 1 and a paper guide plate 2 arranged inside it. Through holes 201 are symmetrically formed on the upper and lower end surfaces of the paper guide plate 2. A polytetrafluoroethylene sheet for reducing the friction between the web paper and the front surface of the paper guide plate 2 is pasted on the front surface of the paper guide plate 2. Limiting plates 3 are symmetrically arranged at the left and right ends of the front surface of the paper guide plate 2, and limiting guide grooves 301 are formed at the side ends of the limiting plates 3. An air suction hood 4 is arranged outside the U-shaped bracket 1. A negative pressure chamber 401 capable of communicating with the through holes 201 on the surface of the paper guide plate 2 is arranged inside the air suction hood 4. The negative pressure chamber 401 is connected to a negative pressure dust removal pipeline through a pressure regulating joint, and the negative pressure dust removal pipeline is externally connected to a negative pressure air suction device.

[0026] In the embodiment of the utility model, a plurality of threaded holes 101 are formed on the side end surface of the U-shaped bracket 1. The paper guide plate 2 is bolted to the inner end surface of the U-shaped bracket 1 through the cooperation of the threaded holes and bolts, and the air suction hood 4 is bolted to the outer end surface of the U-shaped bracket 1 corresponding to the position of the paper guide plate 2, so that the back surface of the paper guide plate 2 can be closely attached to the air suction hood 4, and thus a negative pressure channel is formed between the through holes 201 on the surface of the paper guide plate 2 and the negative pressure chamber 401 of the air suction hood 4, facilitating the smooth adsorption of the web paper passing through the paper guide plate 2 on the front surface of the paper guide plate 2 under the action of a negative pressure environment.

[0027] In the embodiment of the utility model, a plurality of connection holes 202 are formed on the surface of the paper guide plate 2. The connection holes 202 are evenly distributed at the upper and lower ends of the paper guide plate 2 and are located below the through holes 201. The limiting plates 3 can be symmetrically fastened to the front surface of the paper guide plate 2 through the cooperation of the connection holes 202 and bolts. A plurality of through holes 201 are formed, and the plurality of through holes 201 are arranged in a row at the central position of the upper and lower end surfaces of the paper guide plate 2 to adsorb the web paper on the front surface of the paper guide plate 2 under the action of negative pressure suction. A plurality of first threaded holes are formed in the middle of the paper guide plate 2, and the U-shaped bracket 1 and the paper guide plate 2 are fastened together through the cooperation of bolts with the threaded holes 101 and the first threaded holes respectively.

[0028] In the embodiment of the present utility model, the number of the limiting plates 3 is set to two, which are respectively arranged at the left and right ends of the front surface of the paper guide plate 2 in a symmetric form. The limiting guide grooves 301 of the two limiting plates 3 are arranged oppositely, and the groove surfaces of the limiting guide grooves 301 are opened towards the direction of the paper guide plate 2, so that a paper passing channel is formed between the limiting guide grooves 301 of the two limiting plates 3 and the paper guide plate 2. When the reel paper passes through the paper passing channel, one plane of the reel paper contacts the front surface of the paper guide plate 2, and the left and right ends of the reel paper are respectively placed in the spaces surrounded by the limiting guide grooves 301 of the two limiting plates 3 and the front surface of the paper guide plate 2, avoiding the situation that the reel paper comes off from the surface of the paper guide plate 2;

[0029] Specifically, an improved design of reducing the width of the limiting plate 3 is carried out, that is, the opening width of the limiting guide groove 301 of the limiting plate 3 is reduced. If the edge of the reel paper comes off during the process of passing through the paper passing channel, the negative pressure suction at the through hole 201 of the paper guide plate 2 will more easily suck the edge of the reel paper into the paper passing channel from the outer surface of the limiting plate 3;

[0030] In the embodiment of the present utility model, a negative pressure chamber 402 is arranged on the side end surface of the suction hood 4. The number of the negative pressure chambers 402 is set to two. The two negative pressure chambers 402 are respectively located on the upper side surface and the lower side surface of the suction hood 4, and the two negative pressure chambers 402 respectively correspond to the positions of the through holes 201 opened on the upper and lower end surfaces of the paper guide plate 2. A circle of chamber walls is arranged around the surface of the negative pressure chamber 402 towards the direction where the paper guide plate 2 is located. The top end surface of the chamber wall is in close contact with the back surface of the paper guide plate 2. The negative pressure chamber 402 is communicated with the negative pressure cavity 401 through the negative pressure holes opened on the surface of the negative pressure chamber 402; A plurality of second threaded holes are opened in the middle of the suction hood 4. The opening positions of the plurality of second threaded holes on the surface of the suction hood 4 are in a dislocation relationship with the setting position of the negative pressure cavity 401, so that the opening positions of the second threaded holes will not affect the negative pressure environment in the negative pressure cavity 401. The U-shaped bracket 1 and the suction hood 4 are fastened together through the cooperation of the threaded holes 101 and the second threaded holes with bolts respectively;

[0031] In the embodiment of the present utility model, the pressure regulating joint has the function of controlling the magnitude of the negative pressure suction; the negative pressure suction device can provide a negative pressure environment for the negative pressure cavity 401 through the negative pressure dust removal pipeline.

[0032] The specific dimensions of the reel paper guide will be further described as follows:

[0033] The distance between the through hole 201 and the end of the paper guide plate 2 is 2.2 mm, the diameter of the through hole 201 is 1.5 mm, and the number of the through holes 201 opened at each end of the paper guide plate 2 is 13; the width of the limiting plate 3 is 17.5 mm.

[0034] In combination with the above content, the working steps of the utility model are:

[0035] Step S1: starting the negative pressure suction device, which can create a negative pressure environment in the negative pressure channel formed by the through hole 201 on the surface of the paper guide 2 and the suction chamber of the suction hood 4 and the negative pressure cavity 401 of the suction hood 4 through the negative pressure dust removal pipeline;

[0036] Step S2: In step S1, the negative pressure suction force generated by the negative pressure suction device in the negative pressure channel is controlled by the pressure regulating joint, so that a suitable negative pressure environment is formed in the negative pressure channel to avoid the situation where the coil paper is wrinkled at the through hole 201 of the paper guide 2 due to excessive negative pressure suction force;

[0037] Step S3: In step S2, the end of the paper roll is passed through the paper passage formed between the limiting guide groove 301 of the limiting plate 3 and the paper guide 2, so that the left and right ends of the paper roll are respectively placed in the space enclosed by the limiting guide grooves 301 of the two limiting plates 3 and the front of the paper guide 2;

[0038] Step S4: In step S3, the paper coil passing through the front through hole 201 of the paper guide paper 2 is adsorbed to the surface of the paper guide paper 2 under the action of negative pressure suction. As the end of the paper coil gradually moves in the paper feeding channel and moves out from the lower end of the paper feeding channel, the paper coil is positioned and adsorbed to the surface of the paper guide paper 2, ensuring that the edge of the paper coil remains flat at all times.

[0039] After the utility model is applied in actual production, statistics show that the occurrence of overlapping and curled cigarettes is reduced by 28 times, the time spent on parking for cigarettes is reduced by 196 minutes per month, and the amount of residual cigarettes is reduced by 359,000. It can be seen that the implementation effect of the utility model is good, which improves the operating efficiency and reduces the amount of residual cigarettes, thereby reducing the defective rate of cigarettes.
