Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, specifically a bottle dryer with an adjustable blowing angle. Background Technology

[0002] With the continued growth of the global bottled beverage, food, pharmaceutical, and daily chemical packaging industries, the packaging machinery market has entered a period of rapid development. In the filling production lines for products such as beverages, soy sauce, edible oil, and detergents, water droplets often remain on the bottle surface after washing, filling, and capping. If the bottle is not completely dried before the labeling process, residual moisture can cause label bubbling, poor adhesion, or even complete failure to adhere. Therefore, drying the bottle using a blower before labeling, especially at the labeling area, has become an indispensable step in packaging production.

[0003] However, most current blower devices have fixed structures, and the distance between the air outlet and the bottle body, as well as the blowing height, cannot be adjusted. This makes them unsuitable for bottles of different heights and diameters, and they are mostly only suitable for a single size. Therefore, there is an urgent need for a bottle dryer with adjustable blowing distance and height to solve the problem that existing equipment cannot adapt to bottles of different sizes. Summary of the Invention

[0004] In view of the above-mentioned technical deficiencies, the purpose of this invention is to provide a bottle dryer with adjustable blowing angle, which has the advantages of adjustable blowing distance and height.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides a bottle dryer with an adjustable blowing angle, comprising: A workbench is provided with a conveyor belt and a mounting frame, the conveyor belt being used to transport the bottles; The suspension is located above the conveyor belt, and the mounting frame is equipped with a pushing mechanism for pushing the suspension to move vertically up and down; Two sliding plates are slidably connected to a suspension, and a conveyor belt is located below the two sliding plates. The suspension is equipped with a drive mechanism for pushing the two sliding plates closer to or further apart from each other. Two long, narrow air nozzles are hinged to the bottom of the two slide plates and are positioned along the length of the conveyor belt. An adjustment mechanism is provided on each slide and is used to push the blower nozzle to swing along the hinge point between the blower nozzle and the slide. The two blower nozzles can be swinged into an X-shape to blow air under the drive of the adjustment mechanism. A high-pressure blower is installed inside the workbench. The high-pressure blower has two air outlets and is connected to two air nozzles respectively through connecting pipes.

[0006] By adopting the above technical solution, the driving mechanism drives the suspension to move up and down, allowing the blower nozzles to adapt to bottles of different heights. The driving mechanism pushes the two slide plates closer or further apart, making the distance between the blower nozzles and the bottle body adjustable. The adjusting mechanism drives the two blower nozzles to swing around the hinge point and form an X shape. Through the above process, the blowing height, distance, and angle can be adjusted in three dimensions to adapt to various bottle sizes. After adjustment, the conveyor belt sends the bottle body between the two blower nozzles, and the high-pressure blower supplies air to the blower nozzles through the connecting pipe. The X-shaped cross airflow blows obliquely from both sides of the bottle body, effectively covering the bottle body and drying it.

[0007] Preferably, the actuating mechanism includes: Four screws are vertically installed and fixed to the four corners of the top of the suspension. Four drive boxes are fixed on the mounting bracket and correspond one-to-one with four screws. Each drive box is rotatably connected to a worm gear, and the worm gear has a threaded groove. The four screws are respectively inserted into the four drive boxes and threadedly connected to the threaded groove of the worm gear. The top of the screw passes through the drive box and is located above the drive box. The synchronous drive mechanism is mounted on the mounting bracket and connected to four worm gears, which is used to drive the four worm gears to rotate simultaneously.

[0008] Preferably, the synchronous drive mechanism includes: Two rotating shafts are located between two corresponding drive boxes, and the end of each shaft near the drive box passes through the drive box and is rotatably connected to it. Each shaft is provided with two worm sleeves located in the two corresponding drive boxes, and the worm sleeves mesh with the worm wheel. A hand crank, which is fixed to one end of one of the pivots; Two sprockets are fixed to the ends of two shafts opposite to the hand crank, and the two sprockets are connected by a chain drive.

[0009] Preferably, the drive mechanism includes: Two sliding pillars are horizontally and parallelly positioned within the suspension. A lead screw, which is rotatably connected to the suspension and arranged side by side with the sliding column, wherein the lead screw is a bidirectional threaded lead screw; The first hand crank is connected to one end of the lead screw; Both slide plates have grooves that mate with the sliding column. The slide plates slide onto the sliding column through the grooves. One end of the lead screw passes through the two slide plates and is threaded to them. When the lead screw is rotated, the two slide plates move closer to each other or further apart.

[0010] Preferably, the suspension is a rectangular frame, and the sliding column, lead screw, and two sliding plates are all located inside the rectangular frame.

[0011] Preferably, the adjustment mechanism includes: The suspension board is fixed to the bottom of the skateboard, and one end of the blower nozzle is hinged to the suspension board; Side panels, which are fixed to the bottom of the slide and are spaced apart from the suspension plates; The slider is horizontally connected to the bottom of the slide plate and is located between the suspension plate and the side plate; The second lead screw is rotatably connected between the suspension plate and the side plate, and one end of the second lead screw passes through the slider and is threadedly connected to it; The second hand crank is connected to one end of the second lead screw; The upper end of the swing arm is hinged to the slider, and the lower end of the swing arm is inclined away from the suspension plate and hinged to the middle and rear part of the blow nozzle. The hinge points between the blower nozzle and the suspension plate, and the hinge points between the swing arm and the blower nozzle are arranged side by side along the length of the blower nozzle.

[0012] Preferably, the two air nozzles swing under the drive of the adjustment mechanism to form an X-shaped cross air blowing area, the intersection of which is located above the conveyor belt.

[0013] Preferably, the workbench is provided with two fence plates by means of a bracket, and the two fence plates are opposite each other and located on both sides of the conveyor belt. The two fence plates are arranged along the length of the conveyor belt, and the two blow nozzles are located on the outer side of the two fence plates respectively.

[0014] Preferably, apart from the workbench and the conveyor belt, all other structures are in two sets, arranged one after the other along the length of the conveyor belt, and the two blowers in each set can be adjusted to blow air in an X shape.

[0015] Preferably, the connecting pipe includes a conduit and a hose. The conduit is set on the workbench, and one end of the conduit is connected to the air outlet of the high-pressure blower. The other end of the conduit passes through the workbench, is located above the workbench, and is connected to the hose. The end of the hose away from the conduit is connected to the blower nozzle.

[0016] The beneficial effects of this invention are as follows: 1. The device uses a push mechanism to vertically raise and lower the suspension, making the nozzle height adjustable to accommodate bottles of different heights. The drive mechanism moves two sliding plates closer or further apart, adjusting the distance between the nozzle and the bottle to accommodate bottles of different diameters. The adjustment mechanism pushes the nozzle to swing around the hinge point and can be positioned in an X-shape for blowing air, allowing the airflow to cross diagonally from both sides onto the bottle surface, effectively covering the curved surface of the bottle and eliminating blind spots in drying. This achieves three-dimensional adjustment of blowing height, distance, and angle. One device can adapt to multiple bottle sizes, significantly reducing changeover time.

[0017] 2. The driving mechanism adopts four sets of worm gear sleeves in conjunction with the chain for synchronous drive. The four screws lift and lower synchronously, and the suspension moves smoothly without deviation. Moreover, the self-locking characteristic of the worm gear sleeves automatically locks the adjusted height without the need for an additional locking device.

[0018] 3. The drive mechanism adopts a two-way threaded screw and sliding column guide. Rotating the first hand crank can make the two slides move symmetrically, and the blow nozzle is always centered on the bottle body. It has high adjustment accuracy and is easy to operate.

[0019] 4. The adjustment mechanism uses a second lead screw to drive the slider, and pushes and pulls the blower nozzle through the swing rod to form a stable triangular drive structure. The angle adjustment is continuous and precise, and the lead screw self-locks to keep the angle stable.

[0020] 5. The fence prevents the bottle from colliding with the blower nozzle, ensuring the stability of the conveying process. The two sets of structures are arranged one after the other to achieve dual-stage drying, resulting in a significant drying effect.

[0021] 6. The flexible hose connection allows for free adjustment of the blower nozzle, without the constraint of tubing. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1: A bottle dryer with adjustable blowing angle, such as... Figures 1 to 3 As shown, the system includes a workbench 1, a conveyor belt 11, a mounting frame 12, a suspension 2, a pushing mechanism, two sliding plates 21, a drive mechanism, two elongated air nozzles 211, an adjusting mechanism, and a high-pressure blower 14. The conveyor belt 11 and the mounting frame 12 are mounted on the workbench 1. The conveyor belt 11 is used to transport the bottles. The suspension 2 is located above the conveyor belt 11. The pushing mechanism is mounted on the mounting frame 12 and is used to push the suspension 2 to move vertically up and down. The two sliding plates 21 are slidably connected to the suspension 2. The conveyor belt 11 is located below the two sliding plates 21. The drive mechanism is located between the two sliding plates 21. On the suspension 2, two slide plates 21 are used to push them closer or further apart. Two long strip-shaped air nozzles 211 are respectively hinged to the bottom ends of the two slide plates 21 and are arranged along the length of the conveyor belt 11. An adjustment mechanism is set on each slide plate 21 to push the air nozzles 211 to swing along the hinge point between the air nozzles 211 and the slide plate 21. The two air nozzles 211 can be swung into an X-shape for blowing air under the drive of the adjustment mechanism. A high-pressure blower 14 is set inside the workbench 1. The high-pressure blower 14 has two air outlets and is connected to the two air nozzles 211 respectively through connecting pipes 15.

[0027] like Figures 1 to 3As shown, based on the height, diameter, and shape of the bottle to be dried, the pushing mechanism is operated to adjust the blowing height, the driving mechanism to adjust the distance between the blowing nozzle 211 and the bottle body, and the adjusting mechanism to adjust the blowing angle and position the two blowing nozzles 211 into the required X shape. After adjustment, the conveyor belt 11 sends the bottle body between the two blowing nozzles 211, the high-pressure blower 14 is started, and the airflow is sprayed out at high speed from the blowing nozzle 211 through the connecting pipe 15. The X-shaped cross airflow blows obliquely from both sides of the bottle body, blowing off or drying the water droplets on the bottle surface. Through the above process, the blowing height, distance, and angle can be adjusted in three dimensions to adapt to various bottle sizes.

[0028] Example 2: Based on Example 1, as follows Figures 3 to 6 As shown, the driving mechanism includes four screws 24, four drive boxes 25, and a synchronous drive mechanism. The four screws 24 are vertically arranged and fixed to the four top corners of the suspension 2. The four drive boxes 25 are fixed to the mounting bracket 12 and correspond one-to-one with the four screws 24. Each drive box 25 has a worm gear 251 rotatably connected inside it. The worm gear 251 has a threaded groove. The four screws 24 pass through the four drive boxes 25 and are threaded into the threaded grooves of the worm gear 251. The top of the screws 24 passes through the drive box 25 and is located above the drive box 25. The synchronous drive mechanism is set on the mounting bracket 12 and connected to the four worm gears 251 to drive the four worm gears simultaneously. The rotating wheel 251 has a synchronous drive mechanism including two rotating shafts 26, a hand crank 261, two sprockets 262 and a chain 263. The two rotating shafts 26 are located between two corresponding drive boxes 25. The ends of the rotating shafts 26 near the drive boxes 25 pass through the drive boxes 25 and are rotatably connected to them. Each rotating shaft 26 is provided with two worm sleeves 264 located in the two corresponding drive boxes 25, and the worm sleeves 264 mesh with the worm wheel 251. The hand crank 261 is fixed to one end of one of the rotating shafts 26. The two sprockets 262 are fixed to the ends of the two rotating shafts 26 away from the hand crank 261, and the two sprockets 262 are connected by the chain 263. Crank the hand crank 261 to rotate one shaft 26. The sprocket 262 on the shaft 26 drives another shaft 26 to rotate synchronously via the chain 263. The worm gear sleeves 264 on the two shafts 26 drive the worm wheels 251 in the four drive boxes 25 to rotate respectively. The worm wheels 251 drive the four screws 24 to rise and fall simultaneously through the threaded groove, thereby driving the suspension 2 to move smoothly and vertically, thus realizing the height adjustment of the blower nozzle 211. The self-locking characteristic of the worm wheel 251 and worm gear sleeve 264 makes the adjusted height automatically locked.

[0029] like Figure 4As shown, the drive mechanism includes two sliding columns 22, a lead screw 23, and a first hand crank 231. The two sliding columns 22 are horizontally and parallelly arranged in the suspension 2. The lead screw 23 is rotatably connected in the suspension 2 and arranged side by side with the sliding columns 22. The lead screw 23 is a double-threaded lead screw. The first hand crank 231 is connected to one end of the lead screw 23. Each of the two slide plates 21 has a groove that cooperates with the sliding column 22. The slide plate 21 is slidably sleeved on the sliding column 22 through the groove. One end of the lead screw 23 passes through the two slide plates 21 and is threadedly connected to them. When the lead screw 23 is rotated, the two slide plates 21 move closer to each other or further away. The suspension 2 is a rectangular frame. The sliding columns 22, the lead screw 23, and the two slide plates 21 are all located inside the rectangular frame. Rotating the first hand crank 231 drives the lead screw 23 to rotate. The positive and negative threads on the lead screw 23 drive the two slide plates 21 to move closer or further away from each other along the slide column 22. The slide groove and the slide column 22 cooperate to ensure that the slide plates 21 move smoothly. Adjusting the distance between the two blow nozzles 211 and the bottle body can accommodate bottles of different diameters. The bidirectional lead screw 23 makes the two slide plates 21 move symmetrically.

[0030] like Figure 3 and Figure 4 As shown, the adjustment mechanism includes a suspension plate 212, a side plate 213, a slider 214, a second lead screw 215, a second hand crank 2151, and a swing arm 216. The suspension plate 212 is fixed to the bottom end of the slide plate 21. One end of the blower nozzle 211 is hinged to the suspension plate 212. The side plate 213 is fixed to the bottom end of the slide plate 21 and is arranged side-by-side with the suspension plate 212 at intervals. The slider 214 is horizontally slidably connected to the bottom end of the slide plate 21 and is located between the suspension plate 212 and the side plate 213. The second lead screw 215 is rotatably connected to the side plate 216. Between the suspension plate 212 and the side plate 213, one end of the second lead screw 215 passes through the slider 214 and is threaded to it. The second hand crank 2151 is connected to one end of the second lead screw 215. The upper end of the swing arm 216 is hinged to the slider 214. The lower end of the swing arm 216 is inclined away from the suspension plate 212 and is hinged to the middle and rear part of the blower nozzle 211. The hinge points of the blower nozzle 211 and the suspension plate 212, and the hinge points of the swing arm 216 and the blower nozzle 211 are distributed side by side along the length of the blower nozzle 211.

[0031] like Figure 3 and Figure 4 As shown, cranking the second handwheel 2151 drives the second lead screw 215 to rotate, causing the slider 214 to move horizontally. The slider 214 pushes and pulls the middle and rear part of the blower nozzle 211 through the swing rod 216, causing the blower nozzle 211 to swing around the hinge point of the suspension plate 212. Since the two hinge points are distributed along the length direction, a stable triangular drive is formed, the angle adjustment is precise, and the second lead screw 215 self-locks to maintain the angle stability. The two blower nozzles 211 swing under the drive of the adjustment mechanism, as shown. Figure 7This forms an X-shaped cross-blowing area. The intersection of the X-shaped cross-blowing area is located above the conveyor belt 11. The X-shaped airflow acts obliquely and cross-acts on the bottle surface from both sides, blowing off or drying the water droplets on the bottle surface.

[0032] Example 3: Based on Example 2, such as Figures 1 to 3 As shown, two grid plates 131 are provided on the workbench 1 via a bracket 13. The two grid plates 131 are opposite each other and located on both sides of the conveyor belt 11. The two grid plates 131 are arranged along the length of the conveyor belt 11. Two air nozzles 211 are located on the outside of the two grid plates 131 respectively. During operation, part of the air blown out by the air nozzles 211 passes through the gaps on the grid plates 131 (not shown in the figure) and is then blown towards the bottle. The remaining air passes over the top of the grid plates 131 and is then blown towards the bottle. The grid plates 131 prevent the bottle from colliding with the air nozzles 211.

[0033] like Figure 1 As shown, except for the workbench 1 and the conveyor belt 11, all other structures are in two sets. The two sets of structures are arranged back and forth along the length of the conveyor belt 11. The two blow nozzles 211 in each set can be adjusted to blow in an X shape. The bottle is first dried by the first set and then dried by the second set, thus achieving dual-stage enhanced dehydration.

[0034] like Figure 2 As shown, the connecting pipe 15 includes a conduit 151 and a hose 152. The conduit 151 is set on the workbench 1, and one end of the conduit 151 is connected to the air outlet of the high-pressure blower 14. The other end of the conduit 151 passes through the workbench 1 and is located above the workbench 1 and is connected to the hose 152. The end of the hose 152 away from the conduit 151 is connected to the blow nozzle 211. The flexible connection of the hose 152 allows the blow nozzle 211 to move freely when adjusting the height, distance and angle, without the constraint of the pipe.

[0035] The working process of this device is as follows: Adjustment and preparation phase Three-dimensional adjustments are made based on the height, diameter, and shape of the bottle to be dried: Height adjustment: Crank the hand crank 261, which drives the two rotating shafts 26 to rotate synchronously via the chain 263. The worm gear sleeve 264 on the rotating shaft drives the worm wheel 251 in the four drive boxes 25 to rotate. The worm wheel drives the four screws 24 to rise and fall simultaneously, so that the suspension 2 drives the blow nozzle 211 to move vertically as a whole to adapt to bottles of different heights. The worm wheel and worm gear sleeve 264 self-locks to automatically lock the height.

[0036] Distance adjustment: Rotate the first hand crank 231 to drive the lead screw 23 to rotate. The positive and negative threads on the lead screw drive the two slide plates 21 to move closer or further away from each other along the slide column 22, thereby adjusting the distance between the two blow nozzles 211 and the bottle body to adapt to bottles of different diameters.

[0037] Angle adjustment: Crank the second hand crank 2151 to drive the second lead screw 215 to rotate, which in turn drives the slider 214 to move horizontally. The slider pushes and pulls the middle and rear part of the blow nozzle 211 through the swing rod 216, so that the blow nozzle swings around the hinge point of the suspension plate 212, and swings the two blow nozzles 211 into an X shape, so that the intersection of the X-shaped cross blowing area is located above the conveyor belt 11.

[0038] Drying process After adjustment, start the high-pressure blower 14. The airflow is delivered to the two blow nozzles 211 through the conduit 151 and hose 152 of the connecting pipe 15. The conveyor belt 11 sends the bottle between the two blow nozzles. The X-shaped cross airflow blows the bottle body obliquely from both sides. Part of the airflow blows the bottle body through the gap on the grid plate 131, and the remaining part passes over the grid plate. The grid plate also prevents the bottle body from colliding with the blow nozzles. The water droplets on the surface of the bottle body are blown off or dried by the airflow.

[0039] Dual-stage enhanced dehydration (optional) When the equipment is configured with two sets of structures arranged in a front-to-back manner, the bottle body first passes through the first set of drying structures for initial drying, and then passes through the second set for secondary drying, achieving dual-stage enhanced dehydration.

[0040] Production Adjustment When changing to a bottle of a different size, repeat the three steps of the adjustment preparation stage described above. The three-dimensional adjustment can be completed quickly without tools to adapt to the new bottle shape.

[0041] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0042] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
