Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a coating material tank position adjustment device and a coating machine. Background Technology

[0002] A coating machine typically includes a coating roller, a doctor blade, and a feed roller. The feed roller conveys the electrode to be coated to the gap between the coating roller and the feed roller, allowing the slurry on the coating roller to be applied to the electrode. A bottom baffle and a third baffle are usually installed on one side of the coating roller, forming a trough. The desired coating area can be obtained by adjusting the position of the baffles. The amount of material discharged from the trough can be adjusted by regulating the distance between the bottom baffle and the coating roller using a screw, thus achieving the desired coating thickness. However, when adjusting the distance between the bottom baffle and the coating roller, unequal distances often occur, leading to problems such as material leakage from the baffle and uneven coating thickness.

[0003] Therefore, there is an urgent need to design a coating tank position adjustment device and a coating machine to solve the above problems. Utility Model Content

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The coating tank position adjustment device includes:

[0008] The frame includes two fixed plates arranged opposite each other along a first direction;

[0009] The driving mechanism is provided in a one-to-one correspondence with the fixed plate. The driving mechanism includes a lead screw extending along the second direction and a sliding component threadedly connected to the lead screw. The sliding component slides in cooperation with the corresponding fixed plate in the second direction. The bottom of the coating tank is connected to a sliding component at each end of the first direction. The first direction is perpendicular to the second direction.

[0010] As an optional solution, the frame includes two fixing components arranged opposite to each other along the first direction, forming an installation space between the two fixing components. Each fixing component includes a fixing plate and two mounting members. The two mounting members are spaced apart along the second direction and are each connected to the corresponding fixing plate. The lead screw is simultaneously pivotally connected to both mounting members.

[0011] As an optional solution, the aforementioned fixing component further includes a carrier member, which is connected to the corresponding fixing plate and supports the two mounting members. One of the sliding component and the carrier member is provided with a protrusion extending along the second direction, and the other is provided with a second sliding groove extending along the second direction. The second sliding groove and the protrusion slide in cooperation.

[0012] As an optional solution, the aforementioned load-bearing component includes:

[0013] The first bearing part is connected to the corresponding fixed plate, and the second slide groove is formed on the side of the first bearing part away from the fixed plate.

[0014] The second support part is connected to the side of the first support part away from the fixed plate, and the top surface of the second support part is flush with the bottom side wall of the second slide groove.

[0015] The sliding assembly includes a slider and a first connector. The slider and the lead screw are threaded together. The first connector is connected to the side of the slider and has a protrusion. The width of the second bearing portion in the first direction is greater than or equal to the width of the first connector in the first direction.

[0016] As an optional solution, the aforementioned support member further includes an auxiliary support portion, which protrudes from the side of the first support portion away from the second support portion, and the corresponding fixing plate has a groove, with at least a portion of the auxiliary support portion embedded in the groove.

[0017] As an optional solution, the sliding component further includes a second connector, which is detachably connected to the top of the first connector, and the top of the second connector is inclined.

[0018] As an alternative, the top of the first connector has a mounting groove, and the second connector can be detachably installed in the mounting groove.

[0019] As an optional solution, the aforementioned fixing component also includes a reinforcing member, wherein the reinforcing member is connected to one of the aforementioned mounting members at each end in the second direction, and the side of the reinforcing member is connected to the aforementioned fixing plate.

[0021] Coating machine, including:

[0022] The above-mentioned coating tank position adjustment device;

[0023] A coating roller extends along the first direction and is pivotally connected at both ends to one of the fixed plates.

[0024] A coating trough is connected to the sliding assembly to adjust the distance between the coating trough and the coating roller.

[0025] The beneficial effects of this utility model are as follows:

[0026] This utility model provides a coating material tank position adjustment device. The bottom of the coating material tank is also the bottom baffle. A sliding component is connected to both ends of the bottom baffle to ensure the driving balance at both ends of the bottom baffle. Therefore, the coating material tank adjustment device of this utility model can ensure that the direction of the coating material tank is accurate when adjusting the distance between it and the coating roller, and avoid problems such as material leakage from the baffle and uneven coating thickness.

[0027] Furthermore, during the rotation of the lead screw, the sliding component slides in cooperation with the fixed component in the second direction.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] like Figure 1 As shown, the coating machine includes a coating roller 300, a doctor blade 400, and a feeding roller (not shown). The feeding roller conveys the electrode to be coated to the gap between the coating roller 300 and the feeding roller, so that the slurry on the coating roller 300 is coated onto the electrode. Typically, a bottom baffle 210 and a baffle are provided on one side of the coating roller 300, and the three form a material trough, i.e., a coating material trough 200. The coating material trough 200 consists of a bottom baffle 210 and two side baffles 220. The bottom baffle 210 extends along a first direction (X direction in the figure), and the two side baffles 220 are spaced apart and connected to the bottom baffle 210 in the first direction. By adjusting the position of the side baffles 220, the desired coating area can be obtained. By adjusting the distance between the bottom baffle 210 and the coating roller 300 by a screw, the amount of material discharged from the material trough can be adjusted, thereby obtaining the desired coating thickness. However, when adjusting the distance between the bottom baffle 210 and the coating roller 300, there is often a problem that the distance between the bottom baffle 210 and the coating roller 300 is not equal, which leads to problems such as material leakage from the baffle and uneven coating thickness.

[0042] To address the aforementioned problems, this embodiment provides a coating trough position adjustment device, which ensures precise orientation when adjusting the distance between the coating trough 200 and the coating roller 300, thus preventing issues such as material leakage from the baffle and uneven coating thickness. Specifically, as shown... Figure 1 and Figure 2 As shown, the coating tank position adjustment device includes a frame and a drive mechanism 20. The frame includes two fixed plates 111 arranged opposite each other along a first direction. The drive mechanism 20 is arranged in a one-to-one correspondence with the fixed plates 111. The drive mechanism 20 includes a lead screw 21 extending along a second direction (Y direction in the figure, which is perpendicular to the X direction) and a sliding component 22 threadedly connected to the lead screw 21. The sliding component 22 slides in cooperation with the corresponding fixed plate 111 in the second direction. A sliding component 22 is connected to each end of the bottom of the coating tank 200 in the first direction.

[0043] In the above-mentioned coating trough adjustment device, during the rotation of the lead screw 21, due to the action of the thread, the sliding component 22 slides in the second direction with the fixed plate 111. During the movement, the sliding component 22 accurately moves closer to or further away from the coating roller 300 along the second direction. The bottom of the coating trough 200, i.e. the bottom baffle 210, has a sliding component 22 connected to both ends, ensuring the driving balance at both ends of the bottom baffle 210. Therefore, the coating trough adjustment device of this embodiment can ensure that the direction of the coating trough 200 is accurate when adjusting the distance between it and the coating roller 300, avoiding problems such as material leakage from the baffle and uneven coating thickness.

[0044] Furthermore, the frame includes two fixed components 11 arranged opposite each other along a first direction, forming an installation space 12 between the two fixed components 11. Each fixed component 11 includes a fixed plate 111 and two mounting members 112, which are spaced apart along a second direction and each connected to a corresponding fixed plate 111. The lead screw 21 is pivotally connected to both mounting members 112. During movement, the sliding component 22 precisely approaches or moves away from the coating roller 300 along the second direction, effectively improving the stability and accuracy during the sliding process, as well as the accuracy of the direct engagement between the two sliding components 22.

[0045] like Figure 2 As shown, the sliding component 22 includes a slider 221, which is threadedly connected to the lead screw 21. In an optional embodiment (not shown), one of the slider 221 and the fixed plate 111 is provided with a first groove, and the other is provided with a sliding protrusion. Both the first groove and the sliding protrusion extend along the second direction and slide in cooperation with each other, thereby realizing the sliding cooperation between the sliding component 22 and the fixed component 11.

[0046] In this embodiment, as Figure 2 As shown, the fixing component 11 also includes a support member 113, which is connected to the corresponding fixing plate 111 and supports the two mounting members 112. One of the sliding component 22 and the support member 113 is provided with a protrusion 2221 extending in the second direction, and the other is provided with a second groove 1134 extending in the second direction. The second groove 1134 and the protrusion 2221 are slidably engaged. Through the above arrangement, the support member 113 plays the role of supporting the two mounting members 112. Since the two mounting members 112 are pivotally connected to the lead screw 21, they also bear the weight of the coating tank 200. Especially when the coating tank 200 is full of slurry, the weight is very heavy. If the support member 113 is not provided, the two mounting members 112 are prone to deformation or tilting under the action of gravity, causing the adjustment direction to be deviated. The support member 113 distributes most of the weight, preventing the lead screw 21 from deforming.

[0047] Optionally, such as Figure 2As shown, the fixing component 11 also includes a reinforcing member 114. The reinforcing member 114 is connected to a mounting member 112 at each end in the second direction. The side of the reinforcing member 114 is connected to the fixing plate 111. Thus, the reinforcing member 114 connects the two mounting members 112. That is, the upper side of the mounting member 112 is the reinforcing member 114, and the lower side is the bearing member 113. For each mounting member 112, the fixing effect is better and more comprehensive, further preventing the mounting member 112 from tilting and deforming.

[0048] Optionally, such as Figure 2 As shown, the sliding component 22 also includes a first connector 222, which is connected to the side of the slider 221 and has a protrusion 2221. In other embodiments, a protrusion 2221 may also be provided on the lower side of the first connector 222, which is not limited here.

[0049] Optionally, such as Figure 2 As shown, the support member 113 includes a first support portion 1131 and a second support portion 1132. The first support portion 1131 is connected to the corresponding fixed plate 111, and a second sliding groove 1134 is formed on the side of the first support portion 1131 opposite to the fixed plate 111. The second support portion 1132 is connected to the side of the first support portion 1131 opposite to the fixed plate 111, and the top surface of the second support portion 1132 is flush with the bottom sidewall of the second sliding groove 1134. The width of the second support portion 1132 in the first direction is greater than or equal to the width of the first connecting member 222 in the first direction. That is to say, with the protrusion 2221 provided on the side, the provision of the second support portion 1132 can provide large-area support for the first connecting member 222, further increasing the stability of the sliding of the first connecting member 222 during the sliding process.

[0050] Optionally, such as Figure 2 As shown, the bottom of the slider 221 is set to abut against the support member 113, so that the slider 221 is not suspended, thus avoiding the deformation of the lead screw 21 caused by the gravity of the slider 221.

[0051] Optionally, such as Figure 2 and Figure 3 As shown, the support member 113 also includes an auxiliary support portion 1133, which protrudes from the side of the first support member 1131 opposite to the second support member 1132. A corresponding groove 1111 is formed in the fixing plate 111, and at least a portion of the auxiliary support portion 1133 is embedded within the groove 1111. Through this arrangement, the first support member 1131 and the fixing plate 111 are connected, and the embedded auxiliary support portion 1133 increases the bonding strength between the support member 113 and the fixing plate 111.

[0052] Optionally, such as Figure 2As shown, the sliding assembly 22 also includes a second connector 223, which is detachably connected to the top of the first connector 222. The top of the second connector 223 is inclined, so that a second connector 223 of different heights can be selected for coating rollers 300 of different diameters.

[0053] Furthermore, such as Figure 2 As shown, the top of the first connector 222 has a mounting groove 2222, and the second connector 223 can be detachably installed in the mounting groove 2222, which facilitates quick and accurate positioning when installing the second connector 223.

[0054] Optionally, such as Figure 2 As shown, one end of the lead screw 21 is connected to a handle 211, which facilitates manual operation.

[0055] Optionally, such as Figure 2 As shown, an advance / retreat indicator is provided on a mounting component 112 that is far from the coating tank 200 to prevent operator error.

[0056] This embodiment also provides a coating machine, such as Figure 1 As shown, the coating machine includes the aforementioned coating trough position adjustment device, a coating roller 300, and a coating trough 200. The coating roller 300 extends along a first direction and its two ends are pivotally connected to a fixed plate 111. The coating trough 200 is connected to a sliding assembly 22 to adjust the distance between the coating trough 200 and the coating roller 300. By employing the aforementioned coating trough position adjustment device, the distance between the coating trough 200 and the coating roller 300 is uniform, avoiding problems such as material leakage from the baffle and uneven coating thickness.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
