Description

Technical Field

[0001] This utility model relates to the field of heating, and in particular to a heat-resistant transmission component and heating device. Background Technology

[0002] During the processing of workpieces, heat treatment is required. To improve the automation of workpiece heating, a transmission structure is installed in the relevant heating device to automatically move the workpiece into and out of the heating chamber. However, because the transmission structure needs to be located inside the heating chamber, and its heat resistance is insufficient, the workpiece transmission becomes unstable, causing the transmission structure to jam and thus unable to continue moving. Utility Model Content

[0003] This utility model provides a heat-resistant transmission component and a heating device to improve the transmission stability of the transmission component under heated conditions and reduce the risk of the transmission structure being jammed and unable to continue moving.

[0004] A first aspect of this utility model provides a heat-resistant transmission assembly, comprising: a frame; a guide rail fixedly connected to the frame; a guide wheel abutting against the guide rail; a mounting plate rotatably connected to the guide wheel; and a drive structure connected to the guide wheel for driving the guide wheel to move along the extension direction of the guide rail; wherein the guide wheel is floatingly connected to the mounting plate, and the direction of the floating movement of the guide wheel forms an angle with the extension direction of the guide rail.

[0005] In some embodiments, the guide wheel is movable relative to the mounting plate in a first direction, which is perpendicular to the extension direction of the guide rail and parallel to the plane containing the extension trajectory of the guide rail; the guide wheel is movable relative to the mounting plate in a second direction, which is perpendicular to the first direction and also perpendicular to the extension direction of the guide rail.

[0006] In some embodiments, the heat-resistant transmission assembly further includes a connecting plate connecting the guide wheel and the mounting plate; wherein the guide wheel is floatingly connected to the connecting plate and is movable relative to the connecting plate in a first direction, the first direction being parallel to the plane containing the extension trajectory of the guide rail; the connecting plate is floatingly connected to the mounting plate and is movable relative to the mounting plate in a second direction, the second direction being perpendicular to the first direction and perpendicular to the extension direction of the guide rail.

[0007] In some embodiments, two guide wheels are connected to the mounting plate, and in the first direction, the two guide wheels are respectively located on both sides of the guide rail and both guide wheels abut against the guide rail.

[0008] In some embodiments, the heat-resistant transmission assembly further includes a connecting plate that connects the guide wheels and the mounting plate; wherein a plurality of the guide wheels are rotatably connected to the connecting plate, and the connecting plate is rotatably connected to the mounting plate.

[0009] In some embodiments, the drive structure includes: a drive chain connected to the guide wheel; and a sprocket in contact with the drive chain for driving the drive chain to move along the extension direction of the guide rail; wherein the drive chain forms a closed shape, at least a portion of the sprocket is located within the space formed by the drive chain, and another portion of the drive chain is located outside the space formed by the drive chain.

[0010] In some embodiments, the drive chain surrounds a closed shape, with a portion of the drive chain bent toward the inside of the closed shape.

[0011] In some embodiments, the guide rails form a closed shape, and the transmission chain is located within the space formed by the guide rails.

[0012] In some embodiments, at least one of the sprockets located outside the space formed by the drive chain is a drive sprocket.

[0013] A second aspect of this utility model provides a heating device, which includes: a heat-resistant transmission assembly as provided in the first aspect of the above embodiment, and a housing that surrounds the frame to form a heating cavity; a tray located in the heating cavity and connected to the mounting plate; wherein the heat-resistant transmission assembly is used to drive the tray to move into and out of the heating cavity.

[0014] This utility model provides a heat-resistant transmission assembly, which includes a frame, a guide rail fixedly connected to the frame, a guide wheel abutting against the guide rail, a mounting plate rotatably connected to the guide wheel, and a drive structure connected to the guide wheel for driving the guide wheel to move along the extension direction of the guide rail. The drive structure drives the guide wheel to move along the extension direction of the guide rail, enabling automatic transmission between the guide wheel and the mounting plate. The guide wheel and the mounting plate are floatingly connected, and the direction of the floating motion of the guide wheel forms an angle with the extension direction of the guide rail; that is, the direction of the floating motion of the guide wheel is not parallel to the extension direction of the guide rail. This floating connection prevents the movement of the guide wheel from being transmitted to the mounting plate when the guide rail undergoes thermal deformation. It also allows the distance between the guide wheel and the guide rail to adaptively change with the size of the guide rail, thereby improving transmission stability and reducing the risk of the guide wheel getting stuck.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0024] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0025] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0026] In the following specific embodiments, the heat-resistant transmission component can be applied to any heating device requiring heating. For example, the heat-resistant transmission component can be applied to a heat treatment device, and also, for example, to a heating and drying device. The structure and function of the heat-resistant transmission component are described below with reference to various embodiments.

[0027] In some embodiments, combined with Figure 1 and Figure 2 The heat-resistant transmission assembly 10 includes: a frame 100, a guide rail 200, a guide wheel 300, a mounting plate 400, and a drive structure 500; the frame 100 is used to provide installation space for other structures.

[0028] The guide rail 200 is fixedly connected to the frame 100 and is used to guide the movement of the transmission component so that the movement of the transmission component is along a predetermined trajectory. The guide wheel 300 abuts against the guide rail 200, so that the guide wheel 300 moves along the extension direction of the guide rail 200 under the guidance of the guide rail 200. The mounting plate 400 is rotatably connected to the guide wheel 300. When the guide wheel 300 moves along the extension direction of the guide rail 200, it can drive the mounting plate 400 to move along the extension direction of the guide rail 200. At the same time, the rotatable connection between the mounting plate 400 and the guide wheel 300 also allows the guide wheel 300 to rotate relative to the mounting plate 400, thereby defining the friction between the guide wheel 300 and the guide rail 200 as rolling friction, reducing the wear of the guide wheel 300 and the guide rail 200, and extending the service life of the guide wheel 300 and the guide rail 200.

[0029] Among them, such as Figure 2As shown, the guide wheel 300 is floatingly connected to the mounting plate 400. The direction of the floating movement of the guide wheel 300 forms an angle with the extension direction of the guide rail 200. This can be understood as the guide wheel 300 being able to move relative to the mounting plate 400 within a predetermined range in a direction not parallel to the extension direction of the guide rail 200. This allows the guide wheel 300 to still move smoothly along the extension direction of the guide rail 200 even when the guide rail 200 undergoes thermal deformation, and also allows the mounting plate 400 to move smoothly along the extension direction of the guide rail 200. The following explains the reasons for the transmission instability of the transmission assembly and the guide wheel jamming, and explains the principle that the floating connection can improve transmission stability and reduce the risk of jamming.

[0030] Although using a heat-resistant material to prevent the guide rail 200 from directly failing under high external temperatures and avoiding thermal damage due to thermal creep, the guide rail 200 inevitably undergoes thermal deformation under external temperatures. If this thermal deformation occurs in a plane perpendicular to the extended trajectory of the guide rail 200 (hereinafter referred to as the second direction for ease of explanation), it will cause the guide wheel 300 and the mounting plate 400 to vibrate in the second direction during transmission. This vibration affects the stability of the transmission process. By making the guide wheel 300 and the mounting plate 400 float in the second direction, the guide wheel 300 can move relative to the mounting plate 400 in the second direction. This prevents the movement of the guide wheel 300 in the second direction from being transmitted to the mounting plate 400, thereby improving the transmission stability of the mounting plate 400. The movement is smoother; if the thermal deformation generated by the guide rail 200 is parallel to the plane where the extension trajectory of the guide rail 200 is located and perpendicular to the extension direction of the guide rail 200, for ease of explanation, the direction of this thermal deformation is referred to as the first direction below. If the thermal deformation of the guide rail 200 in the first direction is too large, it will cause the guide rail 200 to be excessively pressed against the guide wheel 300, resulting in excessive friction between the guide wheel 300 and the guide rail 200. This excessive friction will cause the guide wheel 300 to be stuck and thus unable to continue moving along the extension direction of the guide rail 200. By making the guide wheel 300 float relative to the mounting plate 400 in the first direction, the guide wheel 300 can move adaptively with the size of the guide rail 200 in the first direction, thereby reducing the friction between the guide wheel 300 and the guide rail 200, and thus reducing the risk of the guide wheel 300 being stuck by the guide rail 200.

[0031] At the same time, such as Figure 1As shown, the drive assembly 500 is connected to the guide wheel and is used to drive the guide wheel 300 to move along the extension direction of the guide rail 200, thereby realizing the automated transmission of the mounting plate 400. The drive assembly 500 can be any structure capable of driving the guide wheel 300 to move. For example, the drive assembly 500 is a rotary motor that drives the guide wheel 300 to rotate, thereby driving the guide wheel 300 to move along the extension direction of the guide rail 200 through the friction between the guide wheel 300 and the guide rail 200. For example, the drive assembly 500 is a transmission chain assembly, and the movement of the transmission chain drives the guide wheel 300 to move along the extension direction of the guide rail 200.

[0032] This utility model provides a heat-resistant transmission assembly, which includes a frame, a guide rail fixedly connected to the frame, a guide wheel abutting against the guide rail, a mounting plate rotatably connected to the guide wheel, and a drive structure connected to the guide wheel for driving the guide wheel to move along the extension direction of the guide rail. The drive structure drives the guide wheel to move along the extension direction of the guide rail, enabling automatic transmission between the guide wheel and the mounting plate. The guide wheel and the mounting plate are floatingly connected, and the direction of the floating motion of the guide wheel forms an angle with the extension direction of the guide rail; that is, the direction of the floating motion of the guide wheel is not parallel to the extension direction of the guide rail. This floating connection prevents the movement of the guide wheel from being transmitted to the mounting plate when the guide rail undergoes thermal deformation. It also allows the distance between the guide wheel and the guide rail to adaptively change with the size of the guide rail, thereby improving transmission stability and reducing the risk of the guide wheel getting stuck.

[0033] In some embodiments, such as Figure 2As shown, the guide wheel 300 can move relative to the mounting plate 400 in a first direction. This first direction is perpendicular to the extension direction of the guide rail and parallel to the plane containing the extension trajectory of the guide rail. This can be understood as the central axis of the guide rail 300's extension direction lying in a plane, with the first direction parallel to this plane and perpendicular to all tangents of this central axis. When the guide rail 200 deforms due to heat in the first direction, the distance between the guide wheel 300 and the guide rail 200 may change. If the guide rail 200 is excessively pressed against the guide wheel 300, the friction between them may become too great, preventing the guide wheel 300 from continuing to extend the guide rail 200's movement. In other words, the guide wheel 300 may be stuck by the guide rail 200. By allowing the guide wheel 300 to float relative to the mounting plate 400 in the first direction, the guide wheel 300 can be prevented from moving. The guide wheel 300 can move adaptively with the dimensions of the guide rail 200 in the first direction, thereby reducing the friction between the guide wheel 300 and the guide rail 200 and reducing the risk of the guide wheel 300 getting stuck in the guide rail 200. The guide wheel 300 can move relative to the mounting plate 400 in the second direction, which is perpendicular to the first direction and the extension direction of the guide rail. That is, the second direction is perpendicular to the plane containing the central axis of the extension direction of the guide rail 200. If the thermal deformation of the guide rail 200 in the second direction is too large, it may cause the guide wheel 300 to vibrate in the second direction during its movement along the extension direction of the guide rail 200. By floating the guide wheel 300 and the mounting plate 400 in the second direction, the vibration of the guide wheel 300 in the second direction will not be transmitted to the mounting plate 400, thereby reducing the impact of the vibration in the second direction on the mounting plate 400 and improving the stability of the transmission. It should be noted that by setting the floating between the guide rail 300 and the mounting plate 400 to float simultaneously in the first and second directions, the structure between the guide rail 300 and the mounting plate 400 becomes more compact.

[0034] In some embodiments, such as Figure 3As shown, the heat-resistant transmission assembly 10 also includes a connecting plate 600, which connects the guide wheel 300 and the mounting plate 400. The guide wheel 300 is rotatably connected to the connecting plate 600. It can be understood that the connecting plate 600 is located between the guide wheel 300 and the mounting plate 400. One side of the connecting plate 600 is fixedly connected to the mounting plate 400, and the other side of the connecting plate 600 is rotatably connected to the guide wheel 300. The guide wheel 300 is floatingly connected to the connecting plate 600 and can move relative to the connecting plate 600 in a first direction. The connecting plate 600 is floatingly connected to the mounting plate 400 and can move relative to the mounting plate 400 in a second direction. It can be understood that by setting the connecting plate 600, the floating connection in the first direction and the floating connection in the second direction can be set at two connection positions respectively, thereby reducing the processing difficulty of the connection structure.

[0035] In some embodiments, such as Figure 3 As shown, two guide wheels 300 are connected to the mounting plate 400. In the first direction, the two guide wheels 300 are located on both sides of the guide rail 200 and both guide wheels 300 abut against the guide rail 200. By clamping the guide rail 200 with the two guide wheels 300, the guide wheels 300 can abut against the guide rail 200 more reliably.

[0036] Optional, such as Figure 4 As shown, the guide rail 200 has limiting grooves 210 on both sides in the first direction. The guide wheel 300 is located in the limiting groove 210 and abuts against the bottom surface of the limiting groove 210, thereby further improving the connection reliability between the guide wheel 300 and the guide rail 200.

[0037] In some embodiments, such as Figure 3 As shown, multiple guide wheels 300 are rotatably connected to the connecting plate 600, and the connecting plate 600 is rotatably connected to the mounting plate 400. This can be understood as follows: when multiple guide wheels 300 are connected to the connecting plate 600, and the guide wheel 300 moves through the curved position of the guide rail 200, the guide wheel 300 will rotate around its own axis of rotation while also revolving relative to the center point of that curved position. This may cause the connecting plate 600 to deflect relative to the guide rail 200. By rotatably connecting the connecting plate 600 to the mounting plate 400, the deflection of the connecting plate 600 will not cause the mounting plate 400 to deflect, thus improving the stability of the transmission.

[0038] In some embodiments, such as Figure 1As shown, the drive structure 500 includes a drive chain 510 and a sprocket 520. The drive chain 520 is connected to the guide wheel 300, and the sprocket 520 contacts the drive chain 510. The contact between the sprocket 520 and the drive chain 510 ensures that the central axis of the drive chain 510's extension direction is parallel to the central axis of the guide rail 200's extension direction. When the drive wheel in the sprocket 510 rotates, it drives the drive chain 510 to move along the extension direction of the guide rail 200. The drive chain 510 forms a closed shape, with at least a portion of the sprocket 520 located within the space formed by the drive chain 510, and the remaining portion of the drive chain 520 located within the space formed by the drive chain 510. For ease of explanation, the space enclosed by the transmission chain 510 will be referred to as the inner side of the transmission chain 510, and the space outside the space will be referred to as the outer side of the transmission chain 510. By setting the sprocket 520 to abut against the transmission chain 510 from both the outer and inner sides, the transmission chain 510 can be clamped on both sides by the sprocket 520, thereby making the abutment between the sprocket 520 and the transmission chain 510 more reliable. The abutment on both sides of the sprocket 520 can also limit the vibration caused by the parallelogram effect of the transmission chain 510 from two directions.

[0039] In some embodiments, such as Figure 1 As shown, the transmission chain 510 surrounds and forms a closed shape. Part of the transmission chain 510 bends toward the inside of the closed shape, so that the transmission chain 510 can bend into a snake-like structure. This bending structure can make fuller use of the space where the transmission chain 510 is located and form a longer transmission chain 510, thereby enabling transmission to more guide wheels 300 and mounting plates 400.

[0040] In some embodiments, such as Figure 1 As shown, the guide rail 300 forms a closed shape, which enables the guide wheel 300 to circulate. The transmission chain 510 is located within the space formed by the guide rail 200, thus protecting the transmission chain 510 and extending its service life.

[0041] In some embodiments, such as Figure 1 As shown, at least one of the sprockets 520 located outside the space formed by the drive chain 510 is a drive sprocket. By setting the sprocket located outside the drive chain 510 as the drive sprocket, the drive sprocket can fit more tightly with the drive chain 510, and the installation and removal of the drive sprocket can be facilitated. Optionally, such as Figure 1 As shown, the drive wheel can move closer to or further away from the transmission chain 510 in the first direction to adjust the clamping force on the transmission chain 510, and at the same time adjust the driving force of the drive wheel on the transmission chain 510.

[0042] This utility model embodiment also provides a heating device, which can be used for heat processing of workpieces or for drying. The structure and function of the heating device are described below with reference to the embodiment.

[0043] In some embodiments, such as Figure 5 As shown, the heating device includes: Figures 1 to 4 The heat-resistant transmission assembly 10, housing 20, and tray 30 are shown in any of the images. Housing 20 and frame 100 surround to form a heating chamber, and tray 30... Figure 2 The mounting plate 400 is fixedly connected, the tray 30 is used to support the workpiece to be heated, and the heat-resistant transmission assembly 10 is used to drive the tray into and out of the heating chamber. During the process of the tray 30 moving into and out of the heating chamber, the operator can install the workpiece to be processed on the tray 30, or remove the heated workpiece from the tray 30. Optionally, multiple workpieces to be processed and multiple trays can be pre-assembled into one unit, and multiple workpieces and trays can be quickly attached to and detached from the mounting plate 400 simultaneously during the assembly and disassembly process.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
