Description

Technical Field

[0001] The utility model relates to the technical field of high-speed packaging machines, in particular to a transparent paper non-return mechanism. Background Art

[0002] Small packages are a very common form of packaging. Small packages are usually packaged with transparent paper strips, so that the products can be displayed to consumers intuitively and are convenient for consumers to purchase. At present, the FX2 high-speed packaging machine is a commonly used small packaging equipment in tobacco packaging production workshops. It is mainly composed of small box packaging forming and wrapping devices, transparent paper wrapping devices, transparent paper cutting devices and other components. This high-speed packaging machine has the advantages of advanced electrical control system, high degree of automation, stable daily equipment operation, high product packaging quality, etc., which greatly improves production efficiency.

[0003] Although the FX2 high-speed packaging machine has the above advantages, it still has the following shortcomings in actual use: when the FX2-753 transparent paper pressing roller is opened, the transparent paper will be pulled back due to the tension generated by the tension of the wire roller and the tension of the transparent paper conveying roller, resulting in the need to re-thread the transparent paper and the wire after processing. The staff generally offsets the tension generated by the tension of the transparent paper traction roller by contacting the transparent paper one-way traction roller with the transparent paper dividing roller, but the tension generated by the tension of the wire roller cannot be offset. Therefore, when maintaining the cutting part or dealing with the transparent paper winding roller failure, there is still the need to re-thread the transparent paper and the wire. In the process of re-threading the transparent paper and the wire, the rework rate is high, and it is difficult for one person to operate. It takes an average of 15 minutes, which increases the workload and seriously affects production efficiency. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art such as high rework rate and difficulty in single-person operation, and to provide a transparent paper non-return mechanism, which has a reasonable design, a simple and ingenious structure, a low manufacturing cost, and is easy to use. It can not only reduce the processing time of transparent paper winding roller failure, but also reduce the amount of defective removal, effectively reduce labor intensity, and improve production efficiency, and is suitable for promotion.

[0005] The utility model is realized through the following technical scheme: a transparent paper non-return mechanism comprises a front bracket of a transparent paper cutting device, a traction roller is arranged inside the front bracket, a guide plate is arranged behind the traction roller, and the traction roller is close to the guide plate; a cylinder frame located above the guide plate is arranged inside the front bracket, a diaphragm clamping cylinder close to the top surface of the guide plate is arranged on the bottom surface of the cylinder frame, and the diaphragm clamping cylinder cooperates with the traction roller and the guide plate to limit the position of the transparent paper.

[0006] A further improvement of the utility model is that the cylinder frame is an "L"-shaped structure, including a vertical plate and a horizontal plate connected in one piece, the cylinder frame is connected to the front bracket via the vertical plate, and the cylinder frame is mounted with a diaphragm to clamp the cylinder via the horizontal plate.

[0007] A further improvement of the utility model is that the height of the vertical plate is 52.5 mm, the length of the horizontal plate is 370 mm, and the width of the horizontal plate is 38 mm.

[0008] A further improvement of the utility model is that the distance between the working surface of the diaphragm clamping cylinder and the guide plate is 5 mm.

[0009] A further improvement of the utility model is that two diaphragm clamping cylinders are provided, and the two diaphragm clamping cylinders are arranged on the same horizontal line.

[0010] A further improvement of the utility model is that the front bracket includes two side plates and a cross bar, the two side plates are arranged in parallel at both ends of the cross bar; the traction roller is installed in front of the cross bar, and the guide plate is installed on the top surface of the cross bar.

[0011] From the above technical scheme, it can be seen that the beneficial effects of the utility model are as follows: by installing the mechanism, the transparent paper is pressed before the entrance of the transparent paper cutting device, so when cutting off the excess transparent paper, there will be no situation where too much or too little transparent paper is cut, and the probability of rework is extremely low. At the same time, when dealing with the winding failure of the FX2-753 transparent paper pressing roller, the operator can operate it alone after simple training, with low difficulty, easy to use, high reliability, and greatly reduced time required for fault handling.

[0018] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0019] Please refer to the attached Figure 1 — Figure 4 , combined with a specific embodiment, it is described as follows: a transparent paper non-return mechanism described in the utility model includes a front bracket 1 of a transparent paper cutting device. Combined with the FX2-753 transparent paper cutting device, the front bracket 1 includes two side panels 101 and a cross bar 102, and the two side panels 101 are arranged in parallel at both ends of the cross bar 102; a traction roller 2 located in front of the cross bar 102 is installed inside the front bracket 1, and a guide plate 3 is installed behind the traction roller 2, that is, on the top surface of the cross bar 102, and the traction roller 2 is close to the guide plate 3.

[0020] A cylinder frame 4 located above the guide plate 3 is arranged inside the front bracket 1. The cylinder frame 4 is an "L"-shaped structure, including a vertical plate 401 and a horizontal plate 402 that are integrally connected; a mounting hole is opened on the vertical plate 401, and the mounting hole corresponds to the reserved hole on the side plate 101; the vertical plate 401 is bolted to the side plate 101 through the mounting hole and the reserved hole, thereby fixing the cylinder frame 4 inside the front bracket 1.

[0021] A diaphragm clamping cylinder 5 is arranged on the bottom surface of the horizontal plate 402, close to the top surface of the guide plate 3. There are two diaphragm clamping cylinders 5, and the two diaphragm clamping cylinders 5 are arranged on the same horizontal line. The distance between the working surface of the diaphragm clamping cylinder 5 and the guide plate 3 is 5 mm. The diaphragm clamping cylinder 5 cooperates with the traction roller 2 and the guide plate 3 to limit the position of the transparent paper.

[0022] Specifically, a connecting hole is provided on the horizontal plate 402 , and the connecting hole corresponds to the assembly hole on the diaphragm clamping cylinder 5 , and the diaphragm clamping cylinder 5 is bolted to the horizontal plate 402 via the connecting hole and the assembly hole.

[0023] The working principle of the utility model is as follows: according to the width of a single sheet of transparent paper being 120mm, the diaphragm clamping cylinder 5 adopts a FESTO EV-20 / 120-5 cylinder, two diaphragm clamping cylinders 5 are connected in parallel, and the clamping area size of the cylinder is 120×20mm, the maximum effective stroke is 5mm, and the working pressure is 2-6bar. When the working air pressure is 2bar and the diaphragm expansion and contraction amount of the diaphragm clamping cylinder 5 is 5mm, the pressure generated is 230N. The distance between the diaphragm clamping cylinder 5 and the guide plate 3 is 5mm, which will not affect the normal production and the material threading requirements.

[0024] When the cylinder is inflated, the diaphragm of the cylinder bulges and acts on the guide plate 3 to press the transparent paper, thereby limiting the position of the transparent paper, that is, achieving the purpose of non-return of the transparent paper. The compressed air is controlled by a two-position three-way control valve. During ventilation, the compressed air is adjusted to the required air pressure through a pressure reducing valve, and finally acts on the diaphragm clamping cylinder 5. When the two-position three-way control switch is closed, the diaphragm clamping cylinder 5 automatically rebounds and exhausts air to return to its original state.

[0025] By installing this mechanism, the transparent paper is pressed before the entrance of the transparent paper cutting device, so when cutting off the excess transparent paper, there will be no excessive or insufficient cutting of transparent paper, and the probability of rework is extremely low. At the same time, when dealing with the winding failure of the FX2-753 transparent paper pressing roller, the operator can operate it alone after simple training, with low difficulty, easy to use, high reliability, and greatly reduced time required for fault handling.

[0026] In one embodiment, the height of the vertical plate 401 is 52.5 mm, the length of the horizontal plate 402 is 370 mm, and the width of the horizontal plate 402 is 38 mm. The above design of the cylinder frame 4 is more reasonable, will not bend or deform, and can meet the design requirements.
