Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and in particular to a drying device for printing tote bags. Background Technology

[0002] Shopping bag printing technology plays a vital role in the modern packaging industry. By printing exquisite designs onto the surface of shopping bags, it not only enhances the product's aesthetics but also improves the brand image. During the shopping bag printing process, ink is transferred to the bag's surface. In existing technologies, drying equipment can be used to dry the ink on the shopping bag, allowing it to quickly cure onto the surface.

[0003] In existing technology, drying equipment generally includes a frame, a conveying assembly, a drying chamber, and a heating assembly. The conveying assembly is mounted on the frame and is used to convey shopping bags. The drying chamber is shrouded above the conveying assembly and is fixedly connected to the frame. The heating assembly is located on the inner wall of the drying chamber and is used to heat the air inside the drying chamber. After the conveying assembly conveys the shopping bags into the drying chamber, the high-temperature air inside the drying chamber dries the ink on the shopping bags.

[0004] In existing technologies, the contact effect between the ink on the shopping bag and the high-temperature air in the drying chamber is poor; therefore, when the ink on the shopping bag is thick, the length of the drying chamber needs to be increased to extend the drying time of the ink on the shopping bag. Utility Model Content

[0005] To improve the drying effect of the drying device on the ink on the tote bag, this application provides a drying device for printing tote bags.

[0006] This application provides a drying device for printing tote bags, which adopts the following technical solution:

[0007] A drying device for printing tote bags includes a frame, a conveying assembly, a drying chamber, a heating assembly, a turbulence-inducing assembly, and a linear reciprocating drive assembly. The conveying assembly is mounted on the frame and is used to convey products. The drying chamber is mounted on the frame and positioned above the conveying assembly. The heating assembly is mounted on the inner peripheral wall of the drying chamber and is used to heat the air inside the drying chamber. The turbulence-inducing assembly is located inside the drying chamber and is fixed to the drive end of the linear reciprocating drive assembly. The linear reciprocating drive assembly drives the turbulence-inducing assembly to perform linear reciprocating motion. The direction of movement of the turbulence-inducing assembly is parallel to the conveying direction of the conveying assembly, and the turbulence-inducing assembly forces the air inside the drying chamber to circulate.

[0008] By adopting the above technical solution, the drying device forces the high-temperature air in the drying chamber to flow towards the shopping bag through the linear reciprocating motion of the turbulence component, so that more high-temperature air comes into contact with the ink on the shopping bag, thereby improving the drying efficiency of the ink on the shopping bag and shortening the drying time of the ink on the shopping bag.

[0009] Optionally, the turbulence assembly includes a turbulence element, and guide surfaces are provided on both sides of the turbulence element along the direction of movement of the turbulence element; the distance from the guide surface to the conveying assembly increases along the direction away from the central axis of the turbulence element; when the turbulence element makes a linear reciprocating motion, the guide surface forces the air to flow towards the conveying assembly.

[0010] By adopting the above technical solution, when the turbulence component performs linear reciprocating motion, the guide surface can force the air in the drying chamber to flow towards the conveying component. This design significantly improves the contact effect between the ink on the tote bag and the high-temperature air, allowing the ink to receive heat energy more evenly and quickly, thereby improving drying efficiency. Especially when processing tote bags with thick ink, sufficient drying can be achieved without lengthening the drying chamber, effectively saving equipment space and improving production efficiency.

[0011] Optionally, the flow-disrupting component further includes a pair of flow guides disposed on the flow-guiding surface. The distance between the two flow guides increases along the direction away from the conveying component, and the closing ends of the two flow guides face the printing area of ​​the product.

[0012] By adopting the above technical solution, the airflow turbulence assembly is equipped with paired guide elements. These guide elements are installed on the airflow guiding surface, and the distance between the two guide elements increases gradually away from the conveying assembly, with the converging end facing the printing area of ​​the product. This design allows the air in the drying chamber to flow more concentratedly towards the printing area of ​​the product when the turbulence elements move, thereby improving the contact efficiency between the ink and the hot air. Specifically, the structural design of the guide elements effectively guides the airflow direction, increases the impact force of the airflow on the printing area, and thus improves the ink drying effect, especially suitable for cases with thicker ink, shortening the drying time required.

[0013] Optionally, the flow guide and the flow spoiler are detachably connected.

[0014] By adopting the above technical solution, the detachable connection design between the airflow guide and the airflow deflector significantly improves the flexibility and ease of maintenance of the device. In actual use, the airflow guide can be quickly replaced or adjusted according to the ink thickness of the tote bag and drying requirements, thereby optimizing the airflow path and improving drying efficiency. At the same time, this detachable structure reduces the difficulty of cleaning and maintenance, extending the overall service life of the device.

[0015] Optionally, the flow guide and the flow deflector are magnetically fixed together.

[0016] By adopting the above technical solution, the flow guide and the flow deflector in the turbulence assembly are fixedly connected by magnetic attraction. This connection method makes the assembly of the flow guide and the flow deflector more convenient, allowing for quick installation and disassembly without additional tools. Simultaneously, the magnetic fixing method offers high stability, effectively preventing the flow guide from loosening or falling off when the flow deflector performs linear reciprocating motion, thus ensuring the normal operation of the drying device. Furthermore, when the shape or size of the flow guide needs to be adjusted for different products, the magnetic fixing method greatly improves replacement efficiency, enhancing the equipment's versatility and flexibility.

[0017] Optionally, an exhaust fan is also included, which is located on the discharge side of the drying chamber and is used to discharge the gas inside the drying chamber to the outside.

[0018] By adopting the above technical solution, the hot air in the drying chamber can be effectively guided by the turbulence component and flow towards the product surface, improving the contact efficiency between the ink and the hot air. Simultaneously, the added exhaust fan, located on the discharge side of the drying chamber, can promptly expel the hot and humid air from the drying chamber to the outside, thereby accelerating the air renewal rate and further improving drying efficiency. This design not only reduces energy loss during the drying process but also enables rapid drying of thicker ink layers without increasing the equipment length, significantly improving the overall efficiency and quality of tote bag printing production.

[0019] Optionally, the flow disruptor is provided with a connecting hole, which is used for gas to pass through when the flow disruptor makes a linear reciprocating motion.

[0020] By adopting the above technical solution, the baffle is equipped with connecting holes. When the baffle makes a linear reciprocating motion, the connecting holes allow gas to pass through, thereby further improving the airflow effect in the drying chamber. Combined with the fact that the movement direction of the baffle is parallel to the conveying direction of the conveying assembly and the design of the guide surfaces on both sides of the baffle, the connecting holes effectively guide the directional flow of air, increasing the contact frequency and intensity between the airflow and the ink on the surface of the tote bag, thus improving the ink drying efficiency. Furthermore, this design can also optimize the airflow distribution in the drying chamber, avoiding airflow stagnation in local areas and improving the overall drying uniformity.

[0021] Optionally, the connecting hole is set at an acute angle to the horizontal plane.

[0022] By adopting the above technical solution, the acute angle between the connecting hole and the horizontal plane optimizes the gas flow path, allowing the gas to flow in a directional manner during the movement of the turbulence-inducing component, further improving the airflow within the drying chamber. This directional flow helps improve the heat exchange efficiency within the drying chamber, ensuring that the ink on the surface of the tote bag is heated evenly, thereby improving drying quality and shortening drying time.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The drying device uses a turbulence-inducing component to reciprocate linearly within the drying chamber, forcing the high-temperature air inside the drying chamber to flow towards the tote bag. This allows more high-temperature air to come into contact with the ink on the tote bag, thereby improving the drying efficiency of the ink on the tote bag and shortening the drying time.

[0025] 2. When the turbulence-inducing component performs linear reciprocating motion, the guide surface forces the air in the drying chamber to flow towards the conveying assembly. This design significantly improves the contact effect between the ink on the tote bag and the high-temperature air, allowing the ink to receive heat energy more evenly and quickly, thereby improving drying efficiency;

[0026] 3. The flow assembly is equipped with paired guide elements, which are mounted on the flow guiding surface. The distance between the two guide elements increases gradually away from the conveying assembly, with the converging end facing the printing area of ​​the product. This design allows the air in the drying chamber to flow more concentratedly towards the product printing area when the turbulence elements move, thereby improving the contact efficiency between the ink and the hot air.

[0034] The following is in conjunction with the appendix Figure 1 Section 6 provides further details regarding this application.

[0035] Example 1

[0036] This application discloses a drying apparatus for printing tote bags. (Refer to...) Figure 1 and Figure 2 The drying device for printing tote bags includes a frame 1, a conveying assembly 2, a drying chamber 3, a heating assembly 4, a turbulence assembly 5, a linear reciprocating drive assembly, and a controller 7. The controller 7 is used to control the operation of the conveying assembly 2, the heating assembly 4, and the linear reciprocating drive assembly.

[0037] A conveying assembly 2 is mounted on the frame 1 and is used to convey the product. The product is a tote bag 8, and the surface of the tote bag 8 has a printing area 81. The drying device of this application is used to dry the ink on the printing area 81 of the tote bag 8. In this embodiment, the conveying assembly 2 is a transmission belt structure, including a drive motor 21, a conveyor roller, and a conveyor belt 22. The drive motor 21 drives the transmission belt to rotate through the conveyor roller to convey the tote bag 8. Since the conveying assembly 2 is prior art, this embodiment will not provide further details about the conveying assembly 2. Figure 1 In the middle, the conveying direction of the handheld device is from right to left; Figure 2 In the middle, the conveying direction of the tote bag 8 is from left to right.

[0038] The drying chamber 3 is mounted on the frame 1 and is positioned above the conveying assembly 2; along the length of the conveying assembly 2, the drying chamber 3 has notches 31 on both sides for the handbag 8 to pass through.

[0039] A heating element 4 is disposed on the inner peripheral wall of the drying chamber 3, and is used to heat the air inside the drying chamber 3. In this embodiment, the heating element 4 includes multiple heating tubes 41, which are used to heat the air inside the drying chamber 3, so that the high-temperature air inside the drying chamber 3 can dry the ink on the tote bag 8. In this embodiment, several temperature sensors are provided inside the drying chamber 3, and the temperature sensors are connected to a controller 7, so that the controller 7 can control the operating power of the heating element 4 according to the actual temperature inside the drying chamber 3.

[0040] The turbulence component 5 is installed inside the drying chamber 3 and is fixed on the drive end of the linear reciprocating drive component. The linear reciprocating drive component drives the turbulence component 5 to perform linear reciprocating motion. The moving direction of the turbulence component 5 is parallel to the conveying direction of the conveying component 2. The turbulence component 5 forces the air inside the drying chamber 3 to flow.

[0041] In this embodiment, the linear reciprocating drive component is a rodless cylinder 6, which has a slide 61 on it. The slide 61 can perform linear reciprocating motion, and the flow-around component is disposed on the slide 61. In other embodiments, the linear reciprocating drive component can also be a linear module, a ball screw, or other structure capable of linear reciprocating drive.

[0042] Reference Figure 2 and Figure 3 The turbulence assembly 5 includes a turbulence element 51, which is fixed to the slide 61 of the rodless cylinder 6, allowing the rodless cylinder 6 to drive the turbulence element 51 to perform linear reciprocating motion. In this embodiment, the cross-section of the turbulence element 51 is an isosceles triangle; that is, along the direction of movement of the turbulence element 51, guide surfaces 511 are provided on both sides of the turbulence element 51; along the direction away from the central axis of the turbulence element 51, the distance from the guide surface 511 to the conveying assembly 2 increases; when the turbulence element 51 performs linear reciprocating motion, the guide surface 511 forces the air to flow towards the conveying assembly 2. (Refer to...) Figure 3 When the flow-enhancing component moves to the left, the guide surface 511 on the left side of the flow-enhancing component 51 forces the high-temperature air to move downward, so that more high-temperature air comes into contact with the ink on the tote bag 8, thereby improving the drying efficiency of the ink on the tote bag 8 and shortening the drying time of the ink on the tote bag 8.

[0043] In addition, the drying device also includes an exhaust fan 9, which is located on the discharge side of the drying chamber 3. The exhaust fan 9 is used to exhaust the gas inside the drying chamber 3 to the outside. When the high-temperature air inside the drying chamber 3 dries the ink on the tote bag 8, the humidity inside the drying chamber 3 will increase. By periodically exhausting the high-temperature and high-humidity air inside the drying chamber 3 through the exhaust fan and replenishing it with fresh air, the drying effect and efficiency of the drying device on the tote bag 8 can be improved.

[0044] The implementation principle of a drying device for printing tote bags according to an embodiment of this application is as follows:

[0045] The drying device uses the reciprocating linear motion of the turbulence component 5 within the drying chamber 3 to force the high-temperature air inside the drying chamber 3 to flow towards the tote bag 8. This design significantly improves the contact effect between the ink on the tote bag 8 and the high-temperature air, allowing the ink to receive heat energy more evenly and quickly, thereby improving drying efficiency. Especially when processing tote bags 8 with thick ink, sufficient drying can be achieved without lengthening the drying chamber 3, effectively saving equipment space and improving production efficiency.

[0046] Example 2

[0047] The difference between Example 2 and Example 1 is as follows:

[0048] Reference Figure 4 and Figure 5 The flow-deflecting assembly 5 also includes a pair of flow guides 52, which are disposed on the flow-guiding surface 511 and are detachably connected to the flow-deflecting components 51. The distance between the two flow guides 52 increases along the direction away from the conveying assembly 2, and the closed ends of the two flow guides 52 face the printing area 81 of the product. In this embodiment, the flow guides 52 and the flow-deflecting components 51 are magnetically fixed, allowing the operator to flexibly adjust the position of the flow guides 52 according to the actual position of the printing area 81 on the tote bag 8.

[0049] The implementation principle of a drying device for printing tote bags according to an embodiment of this application is as follows:

[0050] Reference Figure 4 and Figure 5 The turbulence-disrupting assembly 5 is equipped with paired guide members 52, which are mounted on the guide surface 511. The distance between the two guide members 52 increases in the direction away from the conveying assembly 2, and the converging end faces the printing area 81 of the product. This design allows the air in the drying chamber 3 to flow more concentratedly to the printing area 81 of the product when the turbulence-disrupting assembly 51 moves, thereby improving the contact efficiency between the ink and the hot air.

[0051] Specifically, the structural design of the flow guide 52 effectively guides the airflow direction to improve the ink drying effect, especially suitable for cases where the ink thickness is relatively thick, which can shorten the drying time required.

[0052] Example 3

[0053] The difference between Example 3 and Example 1 is as follows:

[0054] Reference Figure 6 The flow-deflecting component 51 is provided with a connecting hole 512, which allows gas to pass through when the flow-deflecting component 51 performs linear reciprocating motion. In this embodiment, the connecting hole 512 is set at an acute angle to the horizontal plane.

[0055] The implementation principle of a drying device for printing tote bags according to an embodiment of this application is as follows:

[0056] The airflow deflector 51 is provided with a connecting hole 512. When the airflow deflector 51 makes a linear reciprocating motion, the connecting hole 512 allows gas to pass through, thereby further improving the airflow effect in the drying chamber 3. In this embodiment, the connecting hole 512 is inclined, which can effectively guide the airflow up and down to increase the contact frequency and intensity between the high-temperature gas and the ink on the surface of the tote bag 8, thereby improving the ink drying efficiency.

[0057] In addition, this design can optimize the airflow distribution in the drying chamber 3, avoid airflow stagnation in local areas, and improve the overall drying uniformity.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
