Description

Technical Field

[0001] This utility model relates to the field of nonwoven cotton manufacturing technology, and in particular to a cooling and shaping machine with uniform airflow. Background Technology

[0002] For non-woven rigid cotton, it generally requires thermoforming equipment for processing. After thermoforming, it is then cooled and shaped using a cooling and setting machine. Existing cooling and setting machines typically use a mesh conveyor belt to transport the thermoformed non-woven rigid cotton and blow cold air onto both sides of the cotton for rapid cooling and shaping. However, the conveyor belt obstructs the cooling airflow, resulting in lower airflow strength on the lower side of the cotton and preventing simultaneous cooling on both sides. A common approach is to install a fan on each of the upper and lower air ducts and increase the airflow on the lower side to balance the airflow and improve cooling and setting efficiency. However, installing fans on both sides significantly increases equipment costs. Therefore, it is necessary to develop a cooling and setting machine with uniform airflow to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a cooling and shaping machine with uniform airflow to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A cooling and shaping machine with uniform airflow includes a mounting frame, a first duct assembly, a second duct assembly, a connecting pipe assembly, an adjusting assembly, a fan, a conveying drive assembly, and a conveyor belt. Both the first and second duct assemblies are fixed to the mounting frame, with the first duct assembly positioned above the second duct assembly. The connecting pipe assembly includes an integrally formed main connecting pipe and branch connecting pipes. Two sets of branch connecting pipes are provided, with their left ends respectively connected to the first and second duct assemblies. The right ends of both branch connecting pipes are connected to the left end of the main connecting pipe. The fan's outlet end is connected to the right end of the main connecting pipe. Two sets of adjusting assemblies are provided, each corresponding to one of the two branch connecting pipes. The adjusting assemblies include a rotating... The system includes a rod, baffle, support column, track plate, adjusting lever, and locking bolt. The rotating rod is rotatably installed inside the sub-connecting pipe with one end protruding from the sub-connecting pipe. The baffle is fixed on the rotating rod and corresponds to the inside of the sub-connecting pipe. The support column is fixed outside the sub-connecting pipe. The track plate is fixed on the support column and has an arc-shaped hole. One end of the adjusting lever is fixed to the end of the rotating rod. The locking bolt is threaded to the other end of the adjusting lever. One end of the locking bolt passes through the arc-shaped hole and abuts against the outer wall of the sub-connecting pipe. The conveyor drive assembly is fixed on the mounting frame. The conveyor belt is fixed to the power output end of the conveyor drive assembly and surrounds the outer circumference of the second air duct assembly. The conveyor drive assembly drives the conveyor belt to rotate.

[0006] Further description of the present invention: The adjustment assembly also includes a locking nut, which is threadedly connected to a locking bolt. An arc-shaped hole corresponds between the adjustment lever and the locking nut. The front and rear sides of the track plate abut against the adjustment lever and the locking nut, respectively.

[0007] Further description of this utility model: Two sets of baffles are provided and fixed on the left and right sides of the rotating rod.

[0008] Further description of the present invention: The first duct assembly is provided with a ventilation cavity, the cross-sectional area of ​​which gradually decreases along the left side. A ventilation mesh plate is provided on the lower side of the first duct assembly, and multiple sets of ventilation holes are evenly provided on the ventilation mesh plate. An exhaust hole is provided at the left end of the first duct assembly. The structure of the second duct assembly is symmetrical to that of the first duct assembly.

[0009] Further description of the present invention: The conveying drive assembly includes a rotary motor and drive rollers. Both ends of the drive rollers can be rotatably mounted on the mounting frame. Two sets of drive rollers are arranged on the upper and lower sides of the second air duct assembly. The rotary motor is fixed on the mounting frame and its power output end is connected to one set of drive rollers. The conveyor belt surrounds the outer periphery of the four sets of drive rollers.

[0010] The beneficial effects of this utility model are as follows: After the rigid cotton is thermoformed, it is conveyed on a conveyor belt. The conveyor drive assembly drives the conveyor belt to rotate, so that the rigid cotton passes between the first air duct assembly and the second air duct assembly. The fan delivers airflow to the main connecting pipe and delivers air to the first air duct assembly and the second air duct assembly through the two sets of connecting pipes respectively, thereby cooling the rigid cotton from the upper and lower sides. By rotating the adjusting lever, the rotating rod rotates, which in turn drives the baffle to rotate. By adjusting the area of ​​the baffle blocking the channel inside the connecting pipe, the airflow size is controlled. After adjusting the position of the baffle, the locking bolt is rotated to press the locking bolt against the outer wall of the connecting pipe, thereby fixing the position of the rotating rod and the baffle. The arc-shaped hole can limit the movement of the adjusting lever, making it easy to adjust the position of the rotating rod. A scale mark can also be set on one side of the arc-shaped hole to understand the position of the baffle and the blocking area. For the first air duct assembly and the second air duct assembly, the airflow is adjusted in the same way to make the airflow on the upper and lower sides of the rigid cotton similar. The advantages of this design are: it allows for fine-tuning of the airflow in the first and second duct components, making the airflow on both sides of the rigid cotton more even, resulting in more uniform cooling and higher cooling efficiency; on the other hand, the first and second duct components share a common set of fans, which can reduce the manufacturing cost of the equipment.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] like Figures 1 to 5 As shown, a cooling and shaping machine with uniform airflow includes a mounting frame 1, a first duct assembly 2, a second duct assembly 3, a connecting pipe assembly 4, an adjusting assembly 5, a fan 6, a conveying drive assembly 7, and a conveyor belt 8. The first duct assembly 2 and the second duct assembly 3 are both fixed to the mounting frame 1, with the first duct assembly 2 positioned above the second duct assembly 3. The connecting pipe assembly 4 includes an integrally formed main connecting pipe 41 and branch connecting pipes 42. Two sets of branch connecting pipes 42 are provided, with their left ends respectively connected to the first duct assembly 2 and the second duct assembly 3. The right ends of both branch connecting pipes 42 are connected to the left end of the main connecting pipe 41. The air outlet of the fan 6 is connected to the right end of the main connecting pipe 41. Two sets of adjusting assemblies 5 are provided, each corresponding to one of the two branch connecting pipes 42. The adjusting assembly 5 includes a rotating rod 51, a baffle 52, and a support column. 53. Track plate 54, adjusting lever 55 and locking bolt 56. Rotating rod 51 is rotatably installed inside the sub-connecting pipe 42 and one end protrudes from the sub-connecting pipe 42. Baffle 52 is fixed on rotating rod 51 and corresponds to the inside of sub-connecting pipe 42. Support column 53 is fixed outside sub-connecting pipe 42. Track plate 54 is fixed on support column 53. Track plate 54 is provided with arc-shaped hole 541. One end of adjusting lever 55 is fixed to the end of rotating rod 51. Locking bolt 56 is threaded to the other end of adjusting lever 55. One end of locking bolt 56 passes through arc-shaped hole 541 and abuts against the outer wall of sub-connecting pipe 42. Conveying drive assembly 7 is fixed on mounting frame 1. Conveying mesh belt 8 is fixed on the power output end of conveying drive assembly 7 and surrounds the outer periphery of second air duct assembly 3. Conveying drive assembly 7 drives conveying mesh belt 8 to rotate.

[0020] After the rigid cotton is thermoformed, it is conveyed on the conveyor belt 8. The conveyor drive assembly 7 drives the conveyor belt 8 to rotate, so that the rigid cotton passes between the first air duct assembly 2 and the second air duct assembly 3. The fan 6 delivers airflow to the main connecting pipe 41 and delivers air to the first air duct assembly 2 and the second air duct assembly 3 through the two branch connecting pipes 42 respectively, thereby cooling the rigid cotton from both the top and bottom. By rotating the adjusting lever 55, the rotating rod 51 is rotated, which in turn drives the baffle 52 to rotate. The area of ​​the baffle 52 blocking the channels inside the branch connecting pipes 42 is adjusted. This controls the airflow. After adjusting the position of the baffle 52, the locking bolt 56 is rotated to press against the outer wall of the connecting pipe 42, thus fixing the positions of the rotating rod 51 and the baffle 52. The arc-shaped hole 541 restricts the movement of the adjusting lever 55, facilitating the adjustment of the position of the rotating rod 51. A scale marking can also be provided on one side of the arc-shaped hole 541 to indicate the position and coverage area of ​​the baffle 52. The same principle applies to the first duct assembly 2 and the second duct assembly 3, adjusting the airflow to make the airflow on both sides of the rigid cotton more even. The advantages of this design are: it allows for fine-tuning of the airflow in the first duct assembly 2 and the second duct assembly 3, making the airflow on both sides of the rigid cotton more even, resulting in more uniform cooling and higher cooling efficiency. Furthermore, the first duct assembly 2 and the second duct assembly 3 share a common fan 6, reducing equipment manufacturing costs.

[0021] The adjustment assembly 5 also includes a locking nut 57, which is threadedly connected to a locking bolt 56. An arc-shaped hole 541 corresponds between the adjustment lever 55 and the locking nut 57. The front and rear sides of the track plate 54 abut against the adjustment lever 55 and the locking nut 57, respectively.

[0022] By setting the locking nut 57, after adjusting the position of the baffle 52 and tightening the connecting pipe 42 with the locking bolt 56, the adjusting lever 55 is fixed on the track plate 54 by the locking nut 57, further ensuring that the rotating rod 51 no longer rotates, so as to achieve the effect of constant cooling wind force.

[0023] Two sets of baffles 52 are provided and fixed on the left and right sides of the rotating rod 51, so that the weight on both sides of the rotating rod 51 is similar, making it easier and less strenuous to rotate. The shape of the baffles 52 can be set to match the sub-connecting pipes 42, that is, the baffles 52 can completely cover the sub-connecting pipes 42. When some cotton materials only need to be cooled by air supply on one side, one set of sub-connecting pipes 42 can be made not ventilated.

[0024] The first duct assembly 2 has a ventilation cavity 21 inside, the cross-sectional area of ​​the ventilation cavity 21 gradually decreases along the left side, the lower side of the first duct assembly 2 has a ventilation mesh plate 22, the ventilation mesh plate 22 has multiple sets of ventilation holes evenly distributed on it, the left end of the first duct assembly 2 has an exhaust hole 23, and the structure of the second duct assembly 3 is symmetrical to the structure of the first duct assembly 2.

[0025] The left end of the first duct assembly 2 is far from the fan 6. By gradually reducing the cross-sectional area of ​​the ventilation cavity 21 along the left side, the air force at each position on the ventilation mesh 22 can be made similar, making the air outlet more uniform. The left end of the first duct assembly 2 is provided with an exhaust hole 23 so that excess airflow can be discharged.

[0026] The conveying drive assembly 7 includes a rotary motor 71 and drive rollers 72. Both ends of the drive rollers 72 can be rotatably mounted on the mounting frame 1. Two sets of drive rollers 72 are arranged on the upper and lower sides of the second air duct assembly 3. The rotary motor 71 is fixed on the mounting frame 1 and its power output end is connected to one of the sets of drive rollers 72. The conveyor belt 8 surrounds the outer periphery of the four sets of drive rollers 72.

[0027] A rotary motor 71 drives a set of drive rollers 72 to rotate, thereby driving the conveyor belt 8 to rotate. The other three sets of drive rollers 72 are passively rotated under the action of the conveyor belt 8.

[0028] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
