Description

Technical Field

[0001] This utility model relates to the field of hygiene product manufacturing, specifically to a novel mobile ventilation fan. Background Technology

[0002] In the production of sanitary products such as sanitary napkins and panty liners, the blower unit is one of the commonly used pieces of equipment on the production line. Two drive rollers are usually installed at both ends of the blower body to drive the belt. Quick clamps are usually installed on both sides of the drive roller at one end to control the belt tension. In actual use, sometimes the drive roller at the end of the blower without quick clamps is installed close to the cutting tool. In this state, the blower is close to the cutting tool. When changing production models, it is necessary to change the cutting tool. At this time, because the end of the blower is close to the cutting tool, it is not convenient to change the cutting tool. It is necessary to remove the drive roller at the blower to make room for cutting tool change. Since the belt is installed on the drive roller, the belt position and tension need to be readjusted every time the cutting tool is changed, which wastes time and manpower. Utility Model Content

[0003] This utility model discloses a novel mobile air bucket, which can be configured as a first air bucket and a second air bucket. The first air bucket and the second air bucket are connected by a telescopic device and a connecting pipe. The second air bucket is fixed to the mounting plate by an air duct seat. The distance between the first air bucket and the second air bucket is controlled by the telescopic device. Thus, when changing tools, only the telescopic device needs to be controlled to move the first air bucket, so that effective space can be provided for tool changing without disassembling the air bucket.

[0004] This utility model is achieved through the following technical solution.

[0005] A novel mobile air duct includes a mounting plate on which an air duct body is mounted. Drive rollers A and B are mounted at both ends of the air duct body, and a drive roller is mounted below the air duct body. The drive roller is rotatably connected to the mounting plate and drively connected to a driving device. A drive belt is wound around the drive rollers A, B, and drive roller to form a closed loop. The air duct body includes a first air duct body and a second air duct body. The second air duct body is fixed to the mounting plate via a duct seat. A telescopic device is mounted on the second air duct body. The telescopic end of the telescopic device is fixedly connected to the first air duct body to drive its horizontal movement. The first air duct body is connected to the second air duct body via a connecting pipe.

[0006] Furthermore, the telescopic device includes cylinders fixed to both sides of the second air bucket body, and the telescopic rod ends of each cylinder are fixedly connected to the corresponding side wall of the first air bucket body.

[0007] Furthermore, a transition roller bracket is fixedly connected to the lower part of the first air bucket body. Transition rollers A and B are installed on the transition roller bracket, which are arranged vertically. Transition roller A is located close to the transmission roller A. Transition rollers A and B are parallel and staggered. A positioning roller is also fixedly connected to the mounting plate. The positioning roller is fixed below the first air bucket body. The positioning roller and the transition roller bracket are located on the same side of the air duct seat. When the first air bucket body moves to its maximum extension position under the telescopic device, the horizontal distance between the center of the positioning roller and the central axis of the air duct seat is greater than the horizontal distance between the center of the transition roller B and the central axis of the air duct seat.

[0008] Furthermore, the connecting pipe is disposed between the first wind hopper and the second wind hopper, with one end of the connecting pipe fixedly connected to the first wind head body and the other end slidably inserted into a notch on the second wind hopper body, the notch matching the cross-section of the connecting pipe.

[0009] Furthermore, a pressure plate and a pressed seal are installed on the outer edge of the notch. The seal is wrapped around the outer wall of the connecting pipe, and the pressure plate is fixed to the outer wall of the second air duct by fasteners.

[0010] Furthermore, the sealing element is wool felt.

[0011] Compared with the prior art, this utility model has the following advantages.

[0012] In this patent, the air hopper is divided into a first air hopper and a second air hopper. The second air hopper is fixed to the mounting plate via an air duct seat, which is connected to a negative pressure system, creating negative pressure within the second air hopper. The first air hopper is connected to the second air hopper via a connecting pipe, allowing it to also achieve negative pressure adsorption. The first air hopper is fixedly connected to the telescopic end of a telescopic device, allowing it to move closer to or further away from the second air hopper. This provides operating space at the first air hopper for tasks such as changing tools, which can be completed without disassembling the air hopper. To prevent the drive belt from becoming loose during the movement of the first air hopper and getting caught between the first and second air hoppers, a positioning roller and a transition roller bracket are also provided on the mounting plate. When the first air hopper moves to its maximum extension position under the telescopic device, the horizontal distance between the center of the positioning roller and the center axis of the air duct seat is greater than the horizontal distance between the center of the transition roller B and the center axis of the air duct seat. This design ensures that the drive belt will not become loose when the first air hopper retracts, as the total length remains unchanged. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, a novel mobile air duct includes a mounting plate 10, on which an air duct body 20 is mounted. Drive rollers A201 and B202 are respectively mounted at both ends of the air duct body 20. An active roller 30 is mounted below the air duct body 20. The active roller 30 is rotatably connected to the mounting plate 10 and drively connected to a driving device, which may be a drive motor. A drive belt 40 is wound around and drives the drive rollers A201, B202, and 30 to form a closed loop. The air duct body 20 includes a first air duct body 203 and a second air duct body 204. The second air duct body 204 is fixed to the mounting plate 10 via a duct seat 101. A telescopic device is mounted on the second air duct body 204. The telescopic end of the telescopic device is fixedly connected to the first air duct body 203 to drive its horizontal movement. The first air duct body 203 is connected to the second air duct body 204 via a connecting pipe 205.

[0019] Furthermore, the telescopic device includes cylinders 2044 fixed to both sides of the second air bucket body 204, and the telescopic rod ends of each cylinder 2044 are fixedly connected to the corresponding side wall of the first air bucket body 203.

[0020] Furthermore, a transition roller bracket 206 is fixedly connected to the lower part of the first air bucket body 203. Transition rollers A2061 and B2062 are installed on the transition roller bracket 206, which are arranged vertically. The transition roller A2061 is located close to the transmission roller A201. The transition rollers A2061 and B2062 are parallel and staggered. A positioning roller 102 is also fixedly connected to the mounting plate 10. The positioning roller 102 is fixed below the first air bucket body 203. The positioning roller 102 and the transition roller bracket 206 are located on the same side of the air duct seat 101. When the first air bucket body 203 moves to its maximum extension position under the telescopic device, the horizontal distance between the center of the positioning roller 102 and the central axis of the air duct seat 101 is greater than the horizontal distance between the center of the transition roller B2062 and the central axis of the air duct seat 101.

[0021] Furthermore, the connecting pipe 205 is disposed between the first air duct body 203 and the second air duct body 204. One end of the connecting pipe 205 is fixedly connected to the first air duct body 203, and the other end is slidably inserted into the notch 2041 on the second air duct body 204. The notch 2041 matches the cross section of the connecting pipe 205.

[0022] To further improve the sealing effect at the junction of the connecting pipe 205 and the notch 2041, a pressure plate 2042 and a pressed sealing element 2043 are installed on the outer edge of the notch 2041. The sealing element 2043 is wrapped around the outer wall of the connecting pipe 205, and the pressure plate 2042 is fixed to the outer wall of the second air bucket body 204 by fasteners. The sealing element 2043 is wool felt.

[0023] Specifically, one side of the second air duct 204 is vertically fixed to the mounting plate 10 by bolts via the duct seat 101. Generally, the mounting plate 10 can be a wall panel. An adjustment seat can be installed below the duct seat 101 and fixed to the mounting plate 10. Fine adjustments can be made by tightening the bolts on the second air duct 204. One end of the duct seat 101 is fixedly connected to the second air duct 204, and the other end is fixed to the mounting plate 10. A duct is fixed to the other end of the mounting plate 10 to connect to the negative pressure system, thereby generating a negative pressure adsorption effect through the through holes on the air duct 20. The first air duct 203 is fixed to the connecting pipe 205 via a flange. The first air duct 203 and the connecting pipe 205 are in a through-hole state. The other end of the connecting pipe 205 is inserted into the gap of the second air duct 204. Inside the notch 2041, to improve sealing, a pressure plate 2042 is installed on the outer edge of the notch 2041 to press the sealing element 2043. The sealing element 2043 can be made of wool felt. The transition roller bracket 206 is fixed on the first air bucket body 203 and is provided with transition rollers A2061 and B2062. A positioning roller 102 is provided below the first air bucket body 203 and is fixed on the mounting plate 10. By using the movement of the transition roller B2062 located near the positioning roller 102, the belt when the first air bucket body 203 retracts is transferred between the positioning roller 102 and the transition roller B2062, thereby ensuring that the transmission belt is not squeezed between the first air bucket body 203 and the second air bucket body 204 when the first air bucket body 203 moves.

[0024] like Figure 3 As shown, near the first air duct body 203, cylinder gaskets are installed on both sides of the second air duct body 204 and locked to the sides of the second air duct body 204, which are parallel and equal. Cylinder 2044 is installed on the cylinder gaskets. The cylinder model can be TCL50*70. The cylinder rods on both sides are fixed to the sides of the first air duct body 203. When the cylinder extends, it drives the first air duct body 203 to extend forward as a whole. When it retracts, it drives the first air duct body 203 to retract as a whole.

[0025] A transition roller bracket is installed below the first air duct body 203. The transition roller bracket is installed on both sides of the first air duct body 203 and fixed to the first air duct body 203. Transition rollers A2061 and B2062 are installed on the transition roller bracket 206, and the transition rollers A2061 and B2062 are parallel and staggered vertically. At the same time, a positioning roller 102 is installed directly below the first air duct body 203. The positioning roller 102 is rotatably fixed to the base, and the base is fixed to the mounting plate 10. When the cylinder is extended to its maximum value and the belt is taut, the entire air bucket 20 operates normally. When it is necessary to change the production product, the first air bucket 203 needs to be moved. The cylinder 2044 retracts, and the first air bucket 203 and the transition roller bracket 206 move as a whole. Due to the setting of the positioning roller 102, the transmission belt is still taut, which avoids the transmission belt from being caught between the first air bucket 203 and the second air bucket 204 when the first air bucket 203 approaches the second air bucket 204, thus preventing damage to the belt.
