Description

Technical Field

[0001] This utility model relates to the technical field of heating and drying equipment, and in particular to a heating and drying mechanism and drying device. Background Technology

[0002] In product production lines, it is sometimes necessary to design heating and drying processes to heat and dry materials. For example, in product assembly processes, when two glued parts are used as materials to be heated and dried, the glued parts of the two parts are heated and dried to achieve a firm connection between the two parts. Alternatively, if there are gaps in the material, the gaps are filled with sealant and the sealant is cured by heating and drying the gaps in the material. Or, there are other scenarios where materials need to be heated and dried.

[0003] Currently, hot air guns are commonly used to blow hot air onto materials for heating and drying. However, in existing technologies, the nozzle of the hot air gun blows air directly onto one side of the material, resulting in low drying efficiency and high heat loss. Utility Model Content

[0017] Secondly, this utility model provides a drying device, including a base, a translation drive mechanism, and a heating and drying mechanism as described in any optional embodiment of the first aspect;

[0027] Specifically, in the present invention, the term "and / or" indicates that the structure before "and / or" and the structure after "and / or" are set simultaneously or selectively.

[0028] The embodiments of this utility model can achieve at least the following beneficial effects:

[0029] In the heating and drying mechanism provided in this embodiment of the utility model, the ventilation channels inside the directional air blowing lock head include a main ventilation channel and two side ventilation channels. Each side ventilation channel is provided with two side air outlets, which are located on the opposite side walls of each extension facing and away from the outlet groove.

[0030] When in use, bring the end of the directional air blower away from the heating gun close to the material, so that its two extensions are located on both sides of the material. That is, the material is inside the opening groove formed by the side walls (first side wall and third side wall) facing each other of the two extensions and the corresponding end face (second side wall) of the main body. When there are at least two materials, such as material one, material two and material three, the two extensions are respectively located between two adjacent materials. Start the heating gun to heat and dry the materials.

[0031] For material 2 located between the two extensions, since both extensions have a lateral air outlet facing the inside of the opening slot, and this lateral air outlet faces one side surface of material 2, when the heating gun is activated, hot air is blown out from the two lateral air outlets of each extension through the ventilation channel provided inside the directional air blower head. The hot air can at least blow to the opposite two sides of material 2. Furthermore, the blown hot air is reflected between the side surface of material 2 and the side wall surfaces (first side wall and third side wall) of the corresponding extensions facing each other, and flows into the gap between the corresponding end face (second side wall) of material 2 and the main body. Thus, semi-circular air blowing is performed on at least three sides of material 2 in the circumferential direction, improving the drying effect and drying efficiency.

[0032] For materials 1 and 3 located outside the extension, the side air outlets of each extension face one side surface of material 1 and one side surface of material 3, respectively. Thus, when the heating gun is activated, hot air is discharged from the two side air outlets of each extension through the ventilation channel inside the directional air-blowing lock head. The hot air can blow on at least one side surface of material 1 and one side surface of material 3, achieving the effect of drying material 1 and material 3 on one side. When there is more material, after drying material 2, the two extensions can be inserted into the two sides of the material next to material 1 or material 3, so that the material replaces the position of material 2 to perform semi-circular drying of the material. At the same time, the side air outlets of the extension facing away from the outlet will blow on the other side surface of material 1 or material 3, thereby improving the drying efficiency.

[0033] In summary, the heating and drying mechanism provided in this embodiment of the present invention can dry at least three materials simultaneously, and achieves semi-circular air blowing on the materials to improve heat energy utilization, drying effect and drying efficiency.

[0034] Since the drying device provided in this embodiment includes the aforementioned heating and drying mechanism, it can achieve all the functional effects that the aforementioned heating and drying mechanism can achieve. Its specific structure and other beneficial effects can be obtained by referring to the specific implementation section of this specification. Attached Figure Description

[0060] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0061] First aspect

[0062] This embodiment provides a heating and drying mechanism, referring to... Figures 1 to 11 The heating and drying mechanism includes a heating air gun 100 and a directional air blowing lock head 200.

[0063] The heating air gun 100 has an air gun outlet 110.

[0064] Key references Figure 5 and Figure 6The directional air-blowing lock head 200 includes a main body 1 and two extensions 2 connected to one end of the main body 1 and extending in a direction away from the main body 1. The sidewalls (first sidewall 2011 and third sidewall 2013) of the two extensions 2 facing each other and the corresponding end face (second sidewall 2012) of the main body 1 surround each other to form an opening groove 201. The main body 1 is provided with a main ventilation channel 11, and each extension 2 is provided with a side ventilation channel 21 communicating with the main ventilation channel 11. Each extension 2 has a side air outlet 210 communicating with the side ventilation channel 21 on its opposite sidewalls facing and away from the opening groove 201. The end of the main body 1 away from the two extensions 2 is fixedly connected to a heating air gun 100, and the main ventilation channel 11 is connected to the air outlet 110 of the air gun.

[0065] It should be noted that the heating gun 100 is a common tool, mainly used to heat objects by generating a high-temperature airflow. Its main components include a shell, a heating element, and a fan. One end of the shell is provided with a gun outlet 110, and the other end is provided with a gun inlet. The interior is provided with a fluid channel connecting the gun inlet and the gun outlet. The fan is used to draw air from the gun inlet to the gun outlet. The heating element is located in the fluid channel and is used to heat the gas flowing through the fluid channel.

[0066] Reference Figure 5 and Figure 6 In this embodiment, the ventilation channel 2000 inside the directional air-blowing lock head 200 includes a main ventilation channel 11 and two side ventilation channels 21. Each side ventilation channel 21 has two side air outlets 210, which are located on the opposite side walls of each extension 2 facing and away from the outlet groove 201, respectively. The width direction of each extension 2 is perpendicular to its extension direction. The two side air outlets 210 of each extension 2 can be coaxial or non-coaxial along its width direction, preferably coaxial, so that the air volume of the two side air outlets 210 is as uniform as possible.

[0067] In use, the end of the directional air-blowing lock head 200 away from the heating gun 100 is brought close to the material, so that its two extensions 2 are located on both sides of the material. That is, the material is located inside the opening groove 201 formed by the side wall surfaces (first side wall 2011 and third side wall 2013) of the two extensions 2 facing each other and the corresponding end face (second side wall 2012) of the main body 1. When the material has at least two, for example Figure 6 When material 1 510, material 2 520 and material 3 530 are provided, the two extensions 2 are respectively located between two adjacent materials, and the heating gun 100 is started to heat and dry the materials.

[0068] For the material 520 located between the two extensions 2, since both extensions 2 have a lateral air outlet 210 facing the inside of the opening slot 201, when the heating gun 100 is activated, hot air is blown out from the two lateral air outlets 210 of each extension through the ventilation channel 2000 provided inside the directional air outlet 200. The hot air can at least reach the opposite two sides of the material 520. Furthermore, the blown hot air is reflected between the side surface of the material 520 and the side wall surfaces (first side wall 2011 and third side wall 2013) of the corresponding extensions 2, and flows into the gap between the material 520 and the corresponding end face (second side wall 2012) of the main body 1. Thus, at least three sides of the material 520 are semi-circularly blown, improving the drying effect and drying efficiency.

[0069] For material 510 and material 530 located outside the extension 2, each extension 2 faces a side surface of material 510 and a side surface of material 530 respectively, away from the side air outlet 210 of the slot 201. Therefore, when the heating gun 100 is activated, hot air exits from the two side air outlets 210 of each extension through the ventilation channel 2000 inside the directional air outlet 200. This hot air can at least blow hot air onto a side surface of material 510 and a side surface of material 530. The airflow achieves the effect of drying material 1 510 and material 3 530 on one side. When there is more material, after drying material 2 520, the two extensions 2 can be inserted into the two sides of the material next to material 1 510 or material 3 530, so that the material replaces the position of material 2 520 to perform semi-circular drying. At the same time, the side air outlet 210 of the extension 2 away from the outlet groove 201 blows air onto the other side surface of material 1 510 or material 3 530, thereby improving the drying efficiency.

[0070] In summary, the heating and drying mechanism provided in this embodiment can dry at least three materials simultaneously, and achieves semi-circular air blowing on the materials to improve heat energy utilization, drying effect and drying efficiency.

[0071] In this embodiment, the more specific structure of the directional air-blowing lock head 200 is as follows:

[0072] In an optional implementation of this embodiment, refer to Figure 5 and Figure 9For the two extensions 2 of the directional air-blowing lock head 200, the side ventilation channel 21 of each extension 2 includes a guide channel 211 and two diversion channels 212; the guide channel 211 extends along the extension direction of the extension 2, and a connecting port 2110 is provided on each of the opposite side walls of the guide channel 211; one diversion channel 212 connects one connecting port 2110 and a side air outlet 210, and the other diversion channel 212 connects another connecting port 2110 and another side air outlet 210; the flow cross-sectional area of ​​the guide channel 211 is larger than the flow cross-sectional area of ​​each diversion channel 212, and the connecting port 2110 is recessed towards the inside of the guide channel 211.

[0073] In this optional embodiment, the cross-sectional area of ​​the flow channel 211 is larger than that of each diversion channel 212. The design of the connecting port 2110 facing the interior of the flow channel 211 allows the airflow to have a larger flow space before being diverted from the flow channel 211 into the two diversion channels 212. This reduces the flow resistance within the flow channel 211, improves the overall flow efficiency of the side ventilation channel 21, and at the same time helps to guide the airflow more smoothly from the flow channel 211 into the two diversion channels 212, reducing airflow disturbance and energy loss, achieving effective guidance and uniform distribution of airflow, and improving overall ventilation efficiency.

[0074] In an optional embodiment of this example, the end of each extension 2 furthest from the main body 1 is a rod-shaped extension section, and the lateral air outlet 210 is located on the rod-shaped extension section. In this optional embodiment, by designing the extension 2 with rod-shaped extension sections, the two extensions 2 can extend into a smaller gap, and double-sided drying can be achieved for tightly packed materials. In an optional embodiment of this example, the end of each extension 2 furthest from the main body 1 is a rod-shaped extension section, and the lateral air outlet 210 is located on the rod-shaped extension section. In this optional embodiment, by designing the extension 2 with rod-shaped extension sections, the two extensions 2 can extend into a smaller gap, and double-sided drying can be achieved for tightly packed materials, thus adapting to materials of different shapes and sizes; at the same time, the design of the rod-shaped extension sections rectifies the airflow before it is diverted from the guide channel 211 into the two diversion channels 212, so that the airflow can be blown out more evenly from both sides of the extension, improving the consistency of the double-sided drying effect and the simultaneity of drying, and avoiding the problem of one side of the material being overheated or under-dried during the drying process.

[0075] In an optional implementation of this embodiment, refer to Figure 5 and Figure 11The main body 1 of the directional air blower 200, located away from the extension 2, has a mounting hole 12 inside, which communicates with the main ventilation channel 11. The heating air gun 100 has an air gun outlet 110 installed inside the mounting hole 12, either inside the mounting hole 12 or extending into the main ventilation channel 11. Compared to directly connecting the end of the main body 1 of the directional air blower 200 away from the extension 2 to the end of the heating air gun 100 with the air gun outlet 110, this installation method ensures that all the hot air blown from the air gun outlet 110 of the heating air gun 100 flows into the main ventilation channel 11 of the main body 1 of the directional air blower 200, reducing heat loss and improving drying effect. A more specific installation method could be an interference fit between the end of the heating air gun 100 with the air gun outlet 110 and the inner wall of the mounting hole 12, or... Figure 5 As shown, a positioning part 121 is provided inside the mounting hole 12. The positioning part 121 is used to position the corresponding end housing of the heating air gun 100 when one end of the heating air gun 100 with the air gun outlet 110 is inserted into the mounting hole 12. The positioning part 121 may be, but is not limited to, a positioning protrusion corresponding to the positioning groove on the corresponding end housing of the heating air gun 100, or a positioning groove or positioning hole corresponding to the positioning protrusion on the corresponding end housing of the heating air gun 100, or other positioning structures, to prevent the heating air gun 100 from shaking relative to the mounting hole 12 during use, further improving the stability and reliability of the assembly of the directional air blowing lock head 200 and the corresponding end of the heating air gun 100, and reducing the operating noise of the heating and drying mechanism.

[0076] Furthermore, in this optional embodiment, the cross-sectional area of ​​the main ventilation channel 11 is larger than the cross-sectional area of ​​the air gun outlet 110. This optional embodiment, with its larger main ventilation channel 11, helps to distribute the airflow evenly and avoids localized excessive or insufficient airflow caused by concentrated airflow. At the same time, when the airflow enters the main ventilation channel 11 from the air gun outlet 110, the flow velocity decreases and the pressure loss decreases, thereby achieving the effect of reducing flow resistance and improving airflow transmission efficiency.

[0077] In an optional implementation of this embodiment, refer to Figure 5The main ventilation channel 11 of the directional airflow lock head 200 has an elliptical cross-section, and the two side ventilation channels 21 are respectively connected to the two ends of the long axis of the main ventilation channel 11. In this optional embodiment, the elliptical cross-section of the main ventilation channel 11 and the two side ventilation channels 21 are respectively connected to the two ends of the long axis of the main ventilation channel 11, which reduces unnecessary bends and transition structures at the connection between the main ventilation channel 11 and the two side ventilation channels 21. This allows the airflow in the main ventilation channel 11 to be evenly distributed from the center to both sides and smoothly enter the two side ventilation channels 21, reducing the formation of turbulence and eddies when the airflow flows in the main ventilation channel 11, reducing airflow disturbance, improving the stability and efficiency of airflow transmission, and reducing airflow noise, making the heating and drying mechanism quieter during operation.

[0078] In an optional embodiment of this example, the main body 1 of the directional air-blowing lock head 200 can be a one-piece molded structure, or it can be as follows: Figures 1 to 8 As shown: Main body 1 includes main body one 101 and main body two 102 fixedly connected by fasteners; see reference Figure 5 , Figure 10 and Figure 11 The main body 101 has a main ventilation channel 111 inside, and the main body 2 102 has a main ventilation channel 2 112 that communicates with the main ventilation channel 111 inside; the end of the main body 101 away from the main body 2 102 is fixedly connected to the heating air gun 100 and the main ventilation channel 111 communicates with the air gun outlet 110; the extension 2 is connected to the end of the main body 2 102 away from the main body 101, and the side ventilation channel 21 communicates with the main ventilation channel 2 112.

[0079] In this optional embodiment, the main body 1 is divided into main body one 101 and main body two 102 and connected by fasteners to achieve a modular design. This design is beneficial for manufacturing multiple airflow channels in the main ventilation channel 11. The main ventilation channel 11 is divided into main ventilation channel one 111 and main ventilation channel two 112. The airflow passes from the heating air gun 100 through the main ventilation channel one 111 and then enters the main ventilation channel two 112, and flows out through the side ventilation channel 21, reducing the difficulty of channel processing.

[0080] For the specific connection structure of main body 101 and main body 2 102 fixedly connected by fasteners, optionally, as follows: Figure 11 As shown, corresponding fixing holes 103 are provided on the main body 101 and the main body 2 102. Screws, limit pins or other fasteners are installed in the corresponding fixing holes 103 to fix the main body 101 and the main body 2 102 together. The joint between the main ventilation channel 111 of the main body 101 and the main ventilation channel 212 of the main body 2 102 can be sealed and seamlessly connected by a convex and concave sealing surface or by providing a sealing element at the joint surface.

[0081] Second aspect

[0082] This embodiment provides a drying device, referring to... Figure 12 and Figure 13 The drying device includes a base 300, a translation drive mechanism 400, and at least one heating and drying mechanism provided in any optional embodiment of the first aspect. The translation drive mechanism 400 includes a drive unit 41, a moving unit 42, and a mounting base 43. The drive unit 41 is fixedly mounted on the base 300, the moving unit 42 is drively connected to the drive unit 41, and the mounting base 43 is fixedly connected to the moving unit 42. The heating gun 100 is fixedly mounted on the mounting base 43. The drive unit 41 drives the moving unit 42 to move the mounting base 43 horizontally, thereby moving the heating gun 100 horizontally.

[0083] The specific structure and achievable effect of the heating and drying mechanism in the drying device provided in this embodiment can be obtained by referring to the optional or preferred embodiments of the first aspect. In addition, the drying device provided in this embodiment integrates the base 300, the translation drive mechanism 400 and the heating and drying mechanism together. The heating air gun 100 can be moved horizontally by the translation drive mechanism 400 to change the position of the directional air lock head 200, so that the two extensions 2 of the directional air lock head 200 can move forward and backward flexibly, and control the distance between the side air outlet 210 of the extension 2 and the material to be dried to ensure drying efficiency. The material can also be dried by moving back and forth in the horizontal direction during the translation process to avoid the problem of local overheating and deformation of the material.

[0084] More specifically:

[0085] In an optional embodiment of this example, the base 300 includes a platform 31 and multiple legs 32 connected to the lower end of the platform 31; the platform 31 is provided with a guide groove 310 that runs longitudinally through the platform 31 and extends horizontally; the translation drive mechanism 400 also includes a movable bracket 44 that passes through the guide groove 310; the drive unit 41 and the movable unit 42 are located below the platform 31, the portion of the movable bracket 44 located below the platform 31 is fixedly connected to the movable unit 42, and the portion of the movable bracket 44 located above the platform 31 is fixedly connected to the mounting base 43; the drive unit 41 drives the movable unit 42 to move horizontally, and drives the movable bracket 44 to slide along the guide groove 310 with the mounting base 43, thereby moving the heating gun 100 horizontally.

[0086] In this optional embodiment, by placing the drive unit 41 and the moving unit 42 below the platform 31, and connecting the moving unit 42 and the mounting base 43 through the guide groove 310, this layered design makes full use of the space above and below the platform 31, saves space layout, and makes the connection between the components clearer, facilitating installation and maintenance. The cooperative design of the guide groove 310 and the moving bracket 44 can also precisely constrain the horizontal movement path of the mounting base 43 and the heating air gun 100 on it, ensuring stability and accuracy during movement, avoiding uneven drying caused by offset or shaking, and improving the drying efficiency and drying quality of the materials.

[0087] In an optional embodiment of this invention, the platform 31 is further provided with slide rails 311 located on both sides of the guide groove 310, and the mounting base 43 slides in cooperation with the slide rails 311 to further improve the stability and reliability of the translation process.

[0088] Optionally, the platform 31 has a fixed base 33 at its bottom; one of the fixed base 33 and the movable bracket 44 is provided with a press-triggered limit switch 45, and the other is provided with a pressing part 46 facing the press-triggered limit switch 45; the press-triggered limit switch 45 is electrically or signal-connected to the drive unit 41. In this optional embodiment, when the movable bracket 44 moves to a specific position, the pressing part 46 will press the press-triggered limit switch 45, thereby stopping the movement of the drive unit 41. This design can precisely control the movement range of the heating gun 100, prevent it from exceeding the set boundary, and improve the positioning reliability of the two extensions 2 of the directional blower head 200 when they move in the horizontal direction.

[0089] It should be noted that, in this embodiment, the specific structure of the horizontal drive mechanism can optionally include a drive unit that is a cylinder and a moving unit that is a piston rod telescopically connected to the cylinder at one end; the cylinder is horizontally fixedly mounted on the base, and the mounting seat is fixedly connected to the other end of the piston rod away from the cylinder (when a moving bracket is provided, the moving bracket is fixedly connected to the end of the piston rod away from the cylinder, and the mounting seat is fixedly connected to the moving bracket). In other optional embodiments, the horizontal drive mechanism can also be an electric telescopic assembly composed of an electric cylinder and a ball screw nut assembly, or a hydraulic cylinder telescopic rod assembly, or other forms of horizontal drive mechanism, as long as it can realize the function of the drive unit driving the moving unit to move in the horizontal direction, which will not be elaborated further in this specification.

[0090] Finally, it should be noted that:

[0091] 1. In this specification, "and / or" means that the structure before "and / or" and the structure after "and / or" are set simultaneously or selectively;

[0092] 2. The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments.
