Description

Technical Field

[0001] This utility model relates to a nozzle, and more particularly to a quick-disassembly multi-functional slit nozzle. Background Technology

[0002] Existing hot air boxes used in secondary processing fields such as coating typically employ slit nozzles, where air ejected from the nozzle slits directly impacts the substrate surface. In existing systems, the slit nozzle and the plenum are a single unit. During assembly, a gap is left between the top sealing plates of the plenum to form the air outlet slit. This slit is dimensionally fixed by welding, and this accuracy is affected by welding deformation within the plenum and the strength of the thin sheet metal. Controlling the slit's dimensional precision is difficult; once deformed, it cannot be replaced, and the airflow uniformity from the slit is poor, resulting in inconsistent drying effects and impacting product quality. Furthermore, once welded, the slit size and airflow direction are fixed, making adjustment and disassembly impossible, and internal cleaning is difficult.

[0003] In addition, the air ejected from the existing slit nozzles directly impacts the substrate surface. Although this can improve drying efficiency, when the solid content is low, the air from the direct-flow slit nozzles directly impacts the coating surface, which can easily cause the coating to be scratched, resulting in poor product quality and poor product adaptability. Utility Model Content

[0004] To solve the above problems, this utility model provides a quick-disassembly multi-functional slit nozzle, the specific technical solution of which is as follows: A quick-detachable multi-functional slit nozzle includes: a static pressure chamber with a first air outlet; a movable nozzle detachably mounted on the static pressure chamber and communicating with the first air outlet, the movable nozzle having a plurality of slits; a movable baffle rotatably mounted on the movable nozzle and opposite to the slits; and a locking device connected to the movable baffle and the movable nozzle respectively, for fixing the position of the movable baffle so that the movable baffle blocks or avoids the slits.

[0005] Preferably, the interior of the movable nozzle is provided with an air distribution plate, and the air distribution plate is provided with an array of air distribution holes, and the air distribution plate is arranged opposite to the slit.

[0006] Preferably, air guide plates are symmetrically arranged on both sides of the movable baffle, and the air guide plates face the movable nozzle.

[0008] Preferably, it further includes: a seal located between the static pressure chamber and the movable nozzle.

[0009] Furthermore, the movable nozzle is provided with a sealing groove, and the sealing ring is disposed in the sealing groove.

[0010] Preferably, it further includes: a connecting device, which is connected to the movable nozzle and the static pressure box respectively.

[0011] Furthermore, the connecting device includes: a fixed connecting plate disposed at one end of the static pressure box and having a fixed slot; a fixed insert plate disposed at one end of the movable nozzle for inserting into the fixed slot; a positioning seat disposed at the other end of the movable nozzle for abutting against the static pressure box; a locking seat disposed on the positioning seat; and a buckle disposed at one end of the static pressure box for locking onto the locking seat, so that the movable nozzle is fixed on the static pressure box.

[0012] Furthermore, the fixing plate is Z-shaped.

[0013] Preferably, the width of the slit is 0.5~50mm and the length of the slit is 10~500mm.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a quick-disassembly multifunctional slit nozzle. The movable nozzle is detachable by cooperating with a static pressure box, which facilitates processing and maintenance, improves the control accuracy of slit size, and guides or blocks the air blowing through the slit by means of a movable baffle and a locking device, which can prevent air from directly hitting the coating surface and prevent the coating from being blown away.

Detailed Implementation

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] like Figures 1 to 12 As shown, a quick-detachable multi-functional slit nozzle includes a static pressure box 1, a movable nozzle 2, a movable baffle 4, and a locking device 3. The static pressure box 1 has a first air inlet at the top and a first air outlet at the bottom. The movable nozzle 2 is detachably installed at the bottom of the static pressure box 1. The movable nozzle 2 has a second air inlet 21 at the top, which communicates with the first air outlet. The bottom of the movable nozzle 2 has several slits 22. The two ends of the movable baffle 4 are rotatably installed on the movable nozzle 2, and the movable baffle 4 is also arranged opposite to the slits 22. The locking device 3 is connected to the movable baffle 4 and the movable nozzle 2 respectively. The locking device 3 is used to fix the position of the movable baffle 4 so that the movable baffle 4 blocks or avoids the slits 22.

[0018] A quick-detachable multi-functional slit nozzle can be arranged above, below, or both above and below the substrate 9. Depending on the process requirements, the position of the movable baffle 4 can be adjusted to allow the air ejected from the nozzle to be blown directly onto the surface of the substrate 9 to provide a faster evaporation rate for the coating moisture or solvent, thus drying the coating quickly; or the air ejected from the nozzle can be directed away from the surface of the substrate 9 to avoid damaging the coating, but the ejected air can carry away the moisture or solvent evaporated from the coating.

[0019] The shape and number of the second air inlet 21 and the slit 22 on the active nozzle 2 can be designed according to the size and length of the nozzle and the air volume.

[0020] The movable baffle 4 consists of a bottom baffle and lifting lugs 42 symmetrically arranged at both ends of the bottom baffle. The lifting lugs 42 are rotatably installed at both ends of the movable nozzle 2 by pins or screws. The locking device 3 is used to fix the angle of the movable baffle 4. In order to further prevent some air from blowing onto the coating when the movable baffle 4 is blocking the wind, air guide plates 43 are symmetrically arranged on both sides of the movable baffle 4, and the air guide plates 43 face the movable nozzle 2.

[0021] The locking device 3 includes a locking plate 31 and a locking screw 33. The locking plate 31 is fixed to one or both ends of the movable nozzle 2. The locking plate 31 is provided with a plurality of positioning holes 32, and the positioning holes 32 are arranged in a circular array along the rotation axis. The locking screw 33 is threadedly installed on the lug 42 of the movable baffle 4. The locking screw 33 is arranged opposite to the positioning hole 32 and is used to be inserted into the positioning hole 32 to lock the position of the movable baffle 4.

[0022] The movable nozzle 2 has an internal air distribution plate 23, on which a plurality of air distribution holes 24 are arranged in an array. The air distribution plate 23 is positioned opposite to the slit 22. The air distribution holes 24 are designed according to process requirements, and their diameter is adjustable from 3mm to 80mm, and their center distance is adjustable from 5mm to 200mm. The air distribution holes 24 can be arranged in a rectangular array or in a 60° equilateral triangle array.

[0023] To improve the sealing between the static pressure chamber 1 and the movable nozzle 2, a sealing ring 5 is also included between the static pressure chamber 1 and the movable nozzle 2. To facilitate the fixing of the sealing ring 5, the movable nozzle 2 is provided with a sealing groove 51, and the sealing ring 5 is installed in the sealing groove 51.

[0024] This application features a quickly detachable multi-functional slit nozzle. The top plate has a trapezoidal upper section and two horizontal sides at the bottom. Two vertical sides flank the horizontal sides and are fixed to the tops of side plates 1 and 2. The two ends of the top plate are connected to end plates. An air outlet is located in the center of the upper part of the top plate. The air outlet is integrally formed with the top plate without welding. The air outlet is a single row of slits 22, composed of multiple intermittent slits 22. The width of a single slit 22 is 0.5~50mm, the length of a single slit 22 is 10~500mm, and the gap between the slits 22 is 0.5~100mm.

[0025] This application features a quick-disassembly multi-functional slit nozzle. The operating side has a mounting bracket for installing pins and locking bolts, used for mounting and securing the baffle. The drive side has a pin for mounting the baffle.

[0026] This application allows for quick disassembly of a multi-functional slit nozzle. The baffle consists of a base plate and lifting lugs 42. The bottom of the base plate is horizontal, with its two sides at a certain angle to the bottom. The lifting lugs 42 on both sides are perpendicular to the bottom, and holes are opened on the lifting lugs 42 for the pin bolts, pins, and fixing bolts to pass through. The pin bolts and pins are used to hold the baffle and allow the baffle to rotate around the pin bolts and pins to adjust the position and angle of the baffle. The fixing bolts are used to lock and fix the baffle in place after it has been adjusted to the correct position.

[0027] To facilitate the assembly and disassembly of the movable nozzle 2, a connecting device is also included, which connects to both the movable nozzle 2 and the static pressure chamber 1. The connecting device includes a fixed connecting plate 61, a fixed insert plate 62, a positioning seat 63, a retaining seat 64, and a buckle 65. The fixed connecting plate 61 is installed at one end of the static pressure chamber 1 and has a fixed slot. The fixed insert plate 62 is fixed to one end of the movable nozzle 2 and is inserted into the fixed slot. The positioning seat 63 is fixed to the other end of the movable nozzle 2 and is used to abut against the static pressure chamber 1. The retaining seat 64 is fixed to the positioning seat 63. The buckle 65 is fixed to one end of the static pressure chamber 1 and is used to lock onto the retaining seat 64, thus fixing the movable nozzle 2 to the static pressure chamber 1. The fixed insert plate 62 is Z-shaped. The movable nozzle 2 can be quickly assembled and disassembled using the buckle 65 and the fixed connecting plate 61. During disassembly, the operator opens the buckle 65, separating it from the retaining seat 64, and then drags the nozzle, causing the fixed connecting plate 61 to disengage from the fixed slot on the static pressure chamber 1, achieving quick disassembly. The positioning seat 63 also cooperates with the sealing ring 5 to keep the movable nozzle 2 parallel to the static pressure box 1, thereby improving the sealing performance.
