Detailed Implementation

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] In existing packaging bag dryers, a clamping mechanism is used to press the entire surface of the packaging bag, smoothing the surface through mechanical extrusion. However, some bags already contain items, which cannot withstand excessive pressure. Furthermore, existing packaging bag dryers cannot effectively control the distance between the clamping belt and the bag surface. Therefore, products already filled with items cannot be dried using this dryer, resulting in low adaptability. In view of this, if... Figure 1-5 As shown, this utility model provides a packaging bag drying machine with adjustable spacing between the pressing belt and the conveyor belt, comprising: Conveying assembly 1, having a conveying plane for propelling the packaging bag in a directional manner; The pressing component 2 is set on the conveying component 1 with an adjustable distance relative to the conveying plane. The pressing component 2 has a pressing belt 23, which presses the packaging bag by its own weight and moves synchronously with the conveying component 1. The drying component 3 is installed on the conveying component 1 and is used to dry the packaging bag when the packaging bag is laid flat on the conveying plane.

[0021] When the packaging bag is laid on the conveyor plane, the pressing component 2 will press the packaging bag to make the packaging bag lay flat on the conveyor plane. Then the drying component 3 will blow the packaging bag dry. The pressing component 2 can remove the wrinkles on the surface of the packaging bag, which will facilitate the drying component 3 to dry the packaging bag and ensure that the packaging bag is completely dry.

[0022] To increase the contact area between the packaging bag and the conveyor surface, the packaging bag is laid flat on the conveyor belt 14. The conveyor assembly 1 includes: Frame 11 is set on the ground; Several drive rollers 12 are rotatably mounted on the frame 11, wherein two drive rollers 12 are located at both ends of the frame 11 and are on the same horizontal line; A rotary drive unit 13 is mounted on the frame 11. The output end of the rotary drive unit 13 is connected to any one of the transmission rollers 12 for driving the transmission rollers 12 to rotate. The conveyor belt 14 is sequentially mounted on several drive rollers 12 and is connected to them for transmission. When the output end of the rotary drive unit 13 rotates, the drive rollers 12 connected to it rotate synchronously, driving the conveyor belt 14 to move relative to the frame 11, thereby achieving the purpose of conveying the packaging bags. The conveyor belt 14 forms a conveying plane by passing through the area between two drive rollers 12 on the same horizontal line. This arrangement provides a spacious conveying plane for the packaging bags, and the conveyor belt 14 itself is flexible, allowing it to conform to the end face of the packaging bags, thus transporting them effectively.

[0023] To flatten the packaging bag with a larger clamping surface, the clamping assembly 2 includes: The box 21 is vertically mounted on the frame 11 and spaced apart from the conveying plane; Several driven rollers 22 are rotatably mounted on the housing 21, wherein two driven rollers 22 are located at both ends of the housing 21 and are on the same horizontal line; The pressing belt 23 is sequentially mounted on several driven rollers 22 and is connected to the driven rollers 22 for driving. It is used to press the end face of the packaging bag away from the conveying plane so that the packaging bag is laid flat on the conveyor belt 14.

[0024] Specifically, the pressing belt 23 passes through the area between two driven rollers 22 on the same horizontal line to horizontally press the packaging bag. The pressing belt 23 can form a large pressing plane corresponding to the conveying plane. The conveying plane and the pressing plane can ensure that the entire packaging bag is pressed flat, and the wrinkled areas on the packaging bag can be completely removed.

[0025] To accommodate packaging bags of different thicknesses, the spacing between the pressing belt 23 and the conveyor belt 14 needs to be adjusted. The pressing assembly 2 also includes: An adjusting mechanism 24, with one end mounted on the frame 11 and the other end mounted on the housing 21, is used to maintain or change the distance between the housing 21 and the conveyor plane. This allows the distance between the pressing belt 23 and the conveyor belt 14 to be adjustable, enabling the pressing assembly 2 to flatten packaging bags of different thicknesses.

[0026] The regulating mechanism 24 includes: The vertical member 241 has one end fixedly mounted on the frame 11 and the other end extending vertically upward; The horizontal component 242 is fixedly installed at one end of the vertical component 241 that extends outwards, and is parallel to the conveying plane; The linear telescopic unit 243 is mounted on the horizontal member 242 at one end and on the housing 21 at the other end, and is used to adjust the distance between the pressing belt 23 and the conveyor belt 14.

[0027] like Figure 2 and Figure 3 As shown, the linear telescopic unit 243 is configured as a screw structure, and because the contact area between the pressing belt 23 and the conveying plane is large, there are three linear telescopic units 243. The screw structure includes a threaded seat 2431 and a screw 2432. The threaded seat 2431 is fixedly mounted on the horizontal member 242. One end of the screw 2432 is rotatably mounted on the housing 21, and the other end of the screw 2432 extends upward and is threadedly connected to the threaded seat 2431. The distance between the pressing belt 23 and the conveyor belt 14 is adjusted by rotating the screw 2432 relative to the threaded seat 2431, thereby maintaining or adjusting the distance between them.

[0028] The adjustable spacing between the pressing belt 23 and the conveyor belt can prevent the pressing assembly 2 from pressing the entire surface of the packaging bag filled with objects. It can be adjusted to a suitable position so that the pressing belt 23 hangs naturally on the surface of the packaging bag by its own weight. This can easily flatten the packaging bags without damaging the products. Moreover, the adjustable spacing between the pressing belt 23 and the conveyor belt 14 can also flatten packaging bags of different thicknesses, improving the equipment's adaptability to different products.

[0029] Specifically, since the adjusting mechanism 24 can arbitrarily change the distance between the pressing belt 23 and the conveying plane, the packaging bag dryer of this application will also make corresponding adjustments according to the different states of the packaging bags being processed during use. For example, when the packaging bag is not filled with products, the pressing component 2 can be used to lay the packaging bag flat on the conveying plane, eliminate wrinkles on the surface of the packaging bag, and dry the moisture; if the packaging bag contains products, in order to ensure that the products inside the packaging bag are not excessively squeezed and damaged, the adjusting mechanism 24 can be used to move the pressing belt 23 away from the conveying plane, so that the middle part of the pressing belt 23 is located below the two driven rollers 22, that is, the middle part of the pressing belt 23 can hang down naturally and press the packaging bag with its own weight. In this way, the products inside the packaging bag can be laid flat on the conveying plane, so that the packaging bags containing products are conveyed tightly. Only the weight of the pressing belt 23 is used to press the packaging bag, which can ensure that the products are not excessively squeezed and damaged, and also ensure that the products are conveyed tightly in rows and columns.

[0030] To ensure synchronous rotation of the three screw structures, the adjusting mechanism 24 also includes a multi-bar transmission mechanism 244. The multi-bar transmission mechanism 244 is mounted on the horizontal member 242 and simultaneously drives and connects the three screws 2432, enabling them to rotate synchronously and achieve synchronous control. The multi-bar transmission mechanism 244 is a mature and publicly available technology, and will not be described in detail here. In summary, the multi-bar transmission mechanism 244 connects the three screws 2432 via several connecting rods and gears, allowing the torque of one connecting rod to be transmitted simultaneously to all three screws 2432.

[0031] Since both the pressing belt 23 and the conveyor belt 14 are made of flexible materials, in order to further improve the flatness of the packaging bag by the pressing belt 23 and the conveyor belt 14, the pressing assembly 2 also includes: Several flat plates 25 are arranged on the box body 21 and are located between two driven rollers 22 on the same horizontal line. The end faces of the flat plates 25 abut against the side of the pressing belt 23 away from the packaging bag. The conveying assembly 1 also includes several receiving plates 15, which are set on the frame 11 and are arranged one-to-one with several flat plates 25, for pressing the side of the conveyor belt 14 away from the packaging bag.

[0032] The pressing belt 23 is held against one end of the packaging bag by means of the flat plate 25, and the conveyor belt 14 is held against the other end of the packaging bag by means of the receiving plate 15. The pressing belt 23 and the conveyor belt 14 can rigidly flatten the packaging bag, thereby improving the flattening effect of the packaging bag.

[0033] like Figure 1 As shown, in order to synchronize the movement of the conveyor belt 14 and the pressing belt 23, the aforementioned packaging bag dryer also includes: The linkage component 4 is sequentially mounted on the output shaft of the rotary drive unit 13 and any one of the driven rollers 22, and is connected to the rotary drive unit 13 and the driven roller 22 for synchronous conveying of the packaging bag by the conveyor belt 14 and the pressing belt 23.

[0034] Linkage component 4 includes two reversing wheels 41 and a linkage belt 42; Two reversing wheels 41 are rotatably mounted on the frame 11, and the two reversing wheels 41 are respectively located on the left and right sides of the transmission roller 12 connected to the output shaft of the rotary drive unit 13. The linkage belt 42 is sequentially mounted on two reversing wheels 41, a transmission roller 12 connected to the output shaft of the rotary drive unit 13, and any one of the driven rollers 22. The torque of the output shaft of the rotary drive unit 13 is transmitted to the driven roller 22 through the linkage belt 42, so that the driven roller 22 can move synchronously. Furthermore, the driven roller 22 needs to rotate in the opposite direction to the transmission roller 12. The direction of rotation of the driven roller 22 driven by the linkage belt 42 can be changed by the two reversing wheels 41, ultimately achieving the effect of synchronously conveying packaging bags by the conveyor belt 14 and the pressing belt 23.

[0035] In the aforementioned embodiments, in order to reduce the power source, the conveyor belt 14 and the pressing belt 23 are synchronously driven by the same power source using a linkage component 4, which can both reduce the power source and ensure synchronous delivery of packaging bags.

[0036] In some embodiments, the driven roller 22 is connected to an independent drive motor, so that the conveying assembly 1 and the pressing assembly 2 can be driven independently; specifically, the motor is a servo motor to facilitate synchronous control.

[0037] In this embodiment, in order to facilitate the drying of the packaging bag by the drying component 3, the conveyor belt 14 and the pressing belt 23 are hollowed out. The conveyor belt 14 and the pressing belt 23 can be configured as a woven mesh breathable belt, so that airflow can pass through normally.

[0038] On the other hand, this application also provides another embodiment, wherein the pressing band 23 can be configured as a chain plate structure, consisting of a plurality of rectangular plates hinged together, and the adjacent plates are spaced apart to ensure that the dry airflow can pass through the pressing band 23 and be blown onto the surface of the packaging bag. The chain plate structure of the pressing band 23, compared to traditional flexible rubber pressing, can reduce wear on the pressing band 23 and improve its service life.

[0039] Specifically, the drying component 3 includes: Several air inlet pipes 31 are respectively installed on the side of the conveyor belt 14 away from the packaging bag and on the side of the pressing belt 23 away from the packaging bag, to guide airflow to dry both ends of the packaging bag.

[0040] like Figure 3 As shown, there are four flattening plates 25 and four receiving plates 15. The four flattening plates 25 are spaced apart on the housing 21, and the four receiving plates 15 are positioned on the frame 11 corresponding to the four flattening plates 25. Three air inlet pipes 31 are installed between the four flattening plates 25 and between the four receiving plates 15. On the entire conveying plane, the same area of ​​the packaging bag will be dried three times. For example, after a set of flattening plates 25 and receiving plates 15 presses the packaging bag flat, the air inlet pipes 31 immediately ventilate and dry both ends of the packaging bag, repeating this process three times. This ensures that wrinkles on the surface of the packaging bag are completely eliminated and that the packaging bag is completely dry.

[0041] like Figure 5 As shown, in order to adapt to different packaging bags, the required airflow speed for drying packaging bags is also different. Each air inlet pipe 31 is equipped with an air outlet 3101, and the size of the air outlet 3101 is adjustable.

[0042] The drying assembly 3 includes an adjustable nozzle 32, which is located at the air outlet 3101 of the air inlet pipe 31 and is used to change the size of the air outlet 3101.

[0043] The adjustable nozzle 32 includes two elastic plates 321 and an adjusting bolt 322. One end of the two elastic plates 321 is symmetrically arranged on the side of the air outlet 3101, and the other end of the two elastic plates 321 extends toward the packaging bag. The adjusting bolt 322 is threadedly connected to the non-end of the two elastic plates 321. By rotating the adjusting bolt 322, the distance between the two elastic plates 321 can be changed, thereby changing the wind speed of the airflow through the adjustable nozzle 32.

[0044] The working principle of this packaging bag dryer is as follows: The distance between the pressing belt 23 and the conveyor belt 14 is adjusted by the adjusting mechanism 24. When the packaging bag enters the space between the conveyor belt 14 and the pressing belt 23 from one side of the frame 11, the packaging bag is squeezed flat by both of them. The packaging bag is continuously moved by the conveyor belt 14 and the pressing belt 23. When the packaging bag passes through the flat plate 25, the receiving plate 15 and the air inlet pipe 31, the packaging bag will be flattened and dried. This process is repeated many times to achieve complete drying of the packaging.

[0045] Specifically, this packaging bag dryer can also dry products that are about to be boxed, such as chicken feet, kelp strips, spicy strips and other products that are not bagged. After these bagged products are dried and pressed by their own weight to make them flat, it can ensure that the products are neatly arranged. Moreover, after drying, it can also prevent the products from contaminating the packaging box or carton with water.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
