Description

Technical Field

[0001] The utility model discloses a web laying machine with adjustable air duct width, relates to the technical field of non-woven fabric production equipment, and in particular to a web laying machine with adjustable air duct width. Background Art

[0002] A mesh laying machine is primarily used to lay wire mesh or other fabric materials into a flat mesh structure and transport it to intermediate equipment for the next process. To ensure smooth and even transport of the wire mesh or fabric to the next process, the machine typically draws air from the area where the wire mesh or fabric is laid, allowing it to be evenly and smoothly adsorbed to the mesh curtain through this soft, fixed method, and then transported through the mesh curtain. This suction is achieved through the machine's suction duct. Currently, these ducts typically employ a fixed width, which limits the width specifications of the production line. When producing narrow-width products, the existing duct structure maintains a fixed width and length, resulting in a larger suction volume than required. To address this issue, windshields of a certain width are installed on both sides of the suction side of the duct. This reduces the suction area on this side and adjusts the duct's width. However, due to the limited width of the duct, the width of the windshield can only be adjusted within a very small range, which cannot meet the needs of large width changes. In the case of this adjustment, although the fan air volume can be reduced, the operating frequency can be lowered and the operating cost can be reduced, the adjustment amount cannot meet the needs of the production line.

[0003] In view of the problems existing in the above-mentioned prior art, it is very necessary to research and design a new type of web laying machine with adjustable air duct width to overcome the problems existing in the prior art. Summary of the Invention

[0004] The windshields proposed in the prior art have a limited adjustment range and cannot meet the needs of large width changes. Reducing the fan air volume can reduce operating frequency and operating costs, but the adjustment range still cannot meet the needs of the production line. Therefore, a web laying machine with adjustable air duct width is provided. The utility model mainly realizes a web laying machine air duct with adjustable air duct width by making the outermost web suction duct into a movable air duct structure.

[0005] The technical means adopted by this utility model are as follows:

[0006] A web laying machine with adjustable air duct width, wherein the upper portion of the air duct is an air inlet; the air duct is evenly divided into a plurality of fixed air duct partitions by a plurality of partition plates, and the air volume of each air duct partition is controlled by a respective air volume regulating valve, and then the air is discharged from behind the air volume regulating valve; the characteristics are:

[0007] Furthermore, the partition plates adjacent to the end plates at both ends of the air duct are divided into movable partition plates and fixed partition plates, forming air duct partitions with adjustable widths;

[0008] Furthermore, the fixed partition plate is fixedly mounted on the air duct, and the movable partition plate is slidably mounted on the fixed partition plate;

[0009] Furthermore, the movable partition plate is connected to an adjustment structure provided on the air duct end plate, and the adjustment structure drives the movable partition plate to move laterally, thereby adjusting the size of the air duct partition.

[0010] Furthermore, the fixed partition plate is horizontally fixedly assembled at the end of the air duct;

[0011] Furthermore, the fixed partition plate is provided with a slideway for cooperating with the movable partition plate for assembly.

[0012] Furthermore, the movable partition plate is an L-shaped structure;

[0013] Furthermore, the horizontal end of the movable partition plate is slidably connected to the slideway of the fixed partition plate.

[0014] Furthermore, the adjustment structure is divided into two structural forms: a manual adjustment structure and an automatic adjustment structure.

[0015] Furthermore, the manual adjustment structure includes: an adjustment column, a sealing pressure plate and an adjustment column handle;

[0016] Furthermore, the sealing pressure plate is fixed to the end of the air duct by bolts;

[0017] Furthermore, after the adjusting column passes through the sealing pressure plate hole, one end is fixedly connected to the vertical end of the movable partition plate through a fixing bolt and a fixed pressure plate, and the other end is fixedly connected to the adjusting column handle;

[0018] Furthermore, pushing and pulling the adjustment column handle drives the movable partition plate to move horizontally through the adjustment column, thereby changing the width of two adjacent air duct partitions.

[0019] Furthermore, the automatic adjustment structure includes: an adjustment stud, a screw sleeve, a bearing seat and a bearing and an adjustment motor;

[0020] Furthermore, two sets of bearing seats and bearings are fixed to the end of the air duct and the adjacent partition plate inside the movable partition plate by bolts;

[0021] Furthermore, an adjustment column is installed between the two sets of bearing seats and the bearings, one end of the adjustment column is fixed to the partition plate by a fixing bolt, and the other end is fixedly connected to the output end of the adjustment motor;

[0022] Furthermore, the regulating motor rotates to drive the movable partition plate to move horizontally through the regulating column and the screw sleeve, thereby changing the width of two adjacent air duct partitions.

[0023] Furthermore, the regulating column and the air duct end plate are sealed by means of a sealing felt and a sealing pressure plate.

[0024] Furthermore, the adjusting stud and the air duct end plate are sealed by means of a sealing felt and a sealing pressure plate.

[0025] The technical differences between this utility model and the prior art are:

[0026] 1. The structure of the fixed width web laying machine is:

[0027] The upper part is the air inlet of the air duct. In order to achieve the purpose of uniform wind speed, the upper air inlet is evenly divided into several air inlet areas. The air duct end plate and the first partition plate 1 form the first air duct partition, and its air volume is controlled by the air volume regulating valve. Similarly, several air duct partitions such as the second, third, fourth, fifth, and sixth air are formed, all of which are controlled by their own valves. After that, the air is discharged from behind the valve and connected to the suction fan, thus forming the suction of the web laying machine. In the production process of non-woven fabrics, equipment manufacturers need to adjust the width of the finished products of the production line in order to meet customers' demand for the width of non-woven fabrics. If the width of the finished product can be determined as a constant FA or two constants FA or FB, or three constants FA or FB or FC, we set the duct width required for the FA width to A, the duct width required for the FB width to B, and the duct width required for the FC width to C. In this way, we can switch the corresponding air volume regulating valve according to the requirements of the product width, so that air is only sucked in the air duct corresponding to the required width. The air volume regulating valve in other places is closed and no air is sucked, thereby reducing the required air volume, reducing the operating frequency of the fan, and saving operating costs. For example, if we want to produce products with a width of FA or FB, it is obvious that the width FA is a full-width product. In this case, the first to sixth air volume regulating valves need to be opened so that full-width air can be sucked in to produce FA width products. When we want to produce FB width products, we close the first and fourth air volume regulating valves to meet the requirement of producing FB width products. However, due to the large adjustment amount of this width, it cannot be achieved by setting wind shields of a certain width on both sides of the suction side of the suction duct in the width direction. At this time, the first and fourth duct partition air valves are closed, and the corresponding suction duct has no air volume, thereby reducing the overall air volume of the fan, reducing the operating frequency of the fan, and saving operating costs.

[0028] 2. The structure of the web laying machine with manual adjustment of the air duct width is:

[0029] The air inlet of the upper duct is also evenly divided into several air inlet areas, each of which is controlled by an air volume regulating valve. The suction fan discharges air from behind the valve. The first partition plate is separated into two parts, a fixed partition plate and a movable partition plate. The lower fixed partition plate is fixed, and the movable partition plate is fixed to the adjustment column by bolts and a fixed pressure plate. Then, the adjustment column handle welded on the adjustment column is pushed and pulled to pull the movable partition plate out or push it in to move left and right, thereby adjusting the width of the upper air outlet corresponding to the first and second duct partitions, making this area an air duct form with adjustable duct width left and right, and the adjustment width can be determined according to the product width requirements to meet production needs. When producing full-width products, the air volume regulating valves are all opened. When the width becomes smaller, such as the existing paving fan, the first and fifth air volume regulating valves can be closed, thereby reducing the operating air volume of the fan, reducing the operating frequency of the fan, and saving operating costs. Because the adjustment column of the movable partition plate must pass through the duct end plate, a sealing felt is secured to the opening of the duct end plate with bolts and a sealing pressure plate to prevent air leakage. The fifth duct zone is similar to the first duct zone. Both use an adjustment handle to push and pull the adjustment column, which drives the movable partition plate on the right side of the duct to move left and right. This adjusts the width of the corresponding upper air outlet of the fifth and sixth duct zones, making this area a duct with adjustable duct width.

[0030] 3. The structure of the web laying machine with automatic adjustment of air duct width is:

[0031] The air duct adjustment method is the same as the manual adjustment structure, except that the adjustment method is electric instead of manual. The motor is bolted to the crossbeam fixing plate, and the left and right bearings and bearing seats drive the screw to rotate. One side of the screw is bolted to the crossbeam, and the other side is fixed to the fixed partition plate adjacent to the left-right movable air zone plate. A screw sleeve is bolted to the left-right movable partition plate, and the screw thread sections are symmetrically distributed on the sleeve. In this way, when the motor drives the screw to rotate, due to the fixed structure on both sides, the sleeve can move left and right, thereby driving the left-right movable air zone plate to move left and right, thereby adjusting the width of the upper air outlet corresponding to the first air duct partition and the second air duct partition 2, making this area a duct form with adjustable duct width. The adjustable width can be determined according to the product width requirements to meet production needs. When producing full-width products, the air volume control valves are all open. When the width becomes smaller, such as in existing paving fans, the first and fifth air volume control valves can be closed, thereby reducing the fan's operating air volume, reducing the fan's operating frequency, and saving operating costs. Because the adjustment column of the movable partition plate must pass through the duct end plate, a sealing felt is fixed to the opening of the duct end plate with bolts and a sealing pressure plate to prevent air leakage. The fifth duct zone is similar to the first duct zone. In both cases, a motor drives the screw to rotate, which drives the movable partition plate on the right side of the duct to move left and right. This adjusts the width of the corresponding upper air outlet of the fifth and sixth duct zones, making this area a duct with adjustable duct width.

[0032] Compared with the prior art, the utility model has the following advantages:

[0033] 1. The utility model provides a web laying machine with adjustable air duct width, which realizes the adjustment of the air duct width on both sides of the web laying by manual and electric means;

[0034] 2. The utility model provides a web laying machine with adjustable air duct width, which can produce products with multiple widths by adjusting the width of the air ducts on both sides;

[0035] 3. The utility model provides a web laying machine with adjustable air duct width. The width of the air ducts on both sides can be adjusted. When producing products that are not full width, the air ducts on both sides can be closed to reduce the air suction volume of the fan and reduce the operating cost of the fan.

[0036] 4. The utility model provides a web laying machine with adjustable air duct width. By adjusting the air duct width manually or automatically, the width can be adjusted online without stopping the machine for adjustment, thus reducing workload.

[0037] In summary, the technical solution of the present invention solves the problems that the wind shield in the existing technology has a small adjustment range and cannot meet the needs of large-scale changes. By reducing the air volume of the fan, the operating frequency is reduced to reduce the operating cost; but the adjustment amount still cannot meet the needs of the production line.
