[0002] A coating machine is a process production equipment used to apply a material with specific properties to substrates such as paper, aluminum foil, and plastic film.

[0003] In the prior art, a coating machine is needed to coat a roll of substrate with a layer of adhesive, paint or ink with a specific function, and then dry and rewind it. Different substrates require different coating thicknesses. Generally, the distance between the doctor blade and the substrate is adjusted by a screw to obtain a suitable coating thickness. After each use, the paint adhering to the doctor blade needs to be cleaned. In order to facilitate quick disassembly of the doctor blade, this utility model proposes a coating machine with a doctor blade adjustment component. Utility Model Content

[0004] The purpose of this invention is to provide a coating machine with a doctor blade adjustment assembly in order to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating machine with a scraper adjustment assembly, including a base, and a blade holder rotatably connected to the top of the base via a rotating shaft. The top of the blade holder is threadedly connected to a screw rod that passes through the horizontal part of the blade holder and is rotatably connected to the top of a connecting seat. The connecting seat is vertically slidably installed inside the vertical part of the blade holder, and a scraper for scraping coating is installed at the bottom of the connecting seat. The machine also includes a limiting mechanism for quickly replacing the scraper, which is provided on the blade holder and the base.

[0006] The limiting mechanism includes a first limiting unit and a second limiting unit;

[0007] The first limiting unit is used to provide a limit for the installation of the scraper and the connecting seat;

[0008] The second limiting unit is used to provide a limit for the connection between the base and the tool holder.

[0009] As a further embodiment of this utility model: the first limiting unit includes a bolt rod and a limiting block;

[0010] One end of the bolt rod extends into the interior of the connecting seat and is rotatably connected to the inner wall of the connecting seat by threads. The bolt rod is used to drive the limiting block connected at the end to move axially synchronously. One end of the limiting block extends into the end slot of the scraper to provide a limit for the connection between the connecting seat and the scraper.

[0011] As a further embodiment of this utility model: the second limiting unit includes a docking block, a movable rod, a docking rod, and a spring;

[0012] The docking block is fixed at the bottom of the vertical part of the tool holder. The docking block cooperates with the docking rod through the slot opened on the side to complete the connection and positioning of the tool holder and the base. The movable rod is slidably installed on the inner wall of the base and extends to the outside of the base. The docking rod is fixed at the end of the movable rod. The two ends of the spring are respectively connected to the inner wall of the base and the outer wall of the movable rod. The spring is used to provide the movable rod and the docking rod with a constant compressive force in one direction.

[0013] As a further embodiment of this utility model: the side groove of the docking block matches the side outer wall of the docking rod, the side outer wall of the docking rod has an arc-shaped structure, and the inner wall of the base is formed with a sliding groove for the axial movement of the movable rod.

[0014] As a further improvement of this utility model: the end of the scraper is formed with a hole for the insertion of the limiting block, and one end of the outer wall of the limiting block is inclined, so as to better provide the connection force between the scraper and the connecting seat through the inclined end.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By setting a limiting mechanism, when the scraper needs to be replaced and cleaned, an axial thrust can be applied to the movable rod to move the connecting rod out of the side groove of the connecting block, thereby releasing the rotation limit between the scraper holder and the base. This allows the scraper holder to rotate along the connection position with the base, causing the scraper to lie flat. At this time, the bolt rod can be applied to rotate and drive the limiting block to move out of the end groove of the scraper, releasing the limitation on the scraper and facilitating the quick removal of the scraper for replacement and cleaning.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 In this embodiment of the present invention, a coating machine with a scraper adjustment assembly includes a base 1 and a blade holder 2 rotatably connected to the top of the base 1 via a rotating shaft. The top of the blade holder 2 is threadedly connected to a screw 3 that passes through the horizontal part of the blade holder 2 and is rotatably connected to the top of a connecting seat 4. The connecting seat 4 is vertically slidably installed inside the vertical part of the blade holder 2, and a scraper 5 for scraping the coating is installed at the bottom of the connecting seat 4. The machine also includes a limiting mechanism 6 provided on the blade holder 2 and the base 1 for quick replacement of the scraper 5.

[0023] The limiting mechanism 6 includes a first limiting unit and a second limiting unit;

[0024] The first limiting unit is used to limit the installation of the scraper 5 and the connecting seat 4;

[0025] The second limiting unit is used to provide a limit for the connection between the base 1 and the tool holder 2;

[0026] The first limiting unit includes a bolt rod 601 and a limiting block 602;

[0027] One end of the bolt rod 601 extends into the interior of the connecting seat 4 and is threadedly rotatably connected to the inner wall of the connecting seat 4. The bolt rod 601 is used to drive the end-rotatably connected limiting block 602 to move axially synchronously. One end of the limiting block 602 extends into the end slot of the scraper 5 to provide a limit for the connection between the connecting seat 4 and the scraper 5.

[0028] The second limiting unit includes a docking block 603, a movable rod 604, a docking rod 605, and a spring 606;

[0029] The docking block 603 is fixed at the bottom of the vertical part of the tool holder 2. The docking block 603 cooperates with the docking rod 605 through the slot opened on the side to complete the connection and positioning of the tool holder 2 and the base 1. The movable rod 604 is laterally slidably installed on the inner wall of the base 1 and extends to the outside of the base 1. The docking rod 605 is fixed at the end of the movable rod 604. The two ends of the spring 606 are respectively connected to the inner wall of the base 1 and the outer wall of the movable rod 604. The spring 606 is used to provide the movable rod 604 and the docking rod 605 with a pressing force in one direction.

[0030] In this embodiment: By applying rotational force to the screw 3, the connecting seat 4 can be pushed downward or upward along the vertical part of the blade holder 2, thereby adjusting the height of the scraper 5 and the substrate, thus adjusting the coating thickness. After coating is completed, a lateral thrust can be applied to the movable rod 604, causing the movable rod 604 to simultaneously push the docking rod 605 laterally. The moving movable rod 604 applies a compressive force to the spring 606 until the docking rod 605 moves out of the side slot of the docking block 603, thereby releasing the rotational limitation between the blade holder 2 and the base 1. At this time, rotational force can be applied to the blade holder 2 to expose a removable space between the connecting seat 4 and the base 1. By applying rotational force to the bolt rod 601, the top limiting block 602 moves out of the end slot of the scraper 5, thereby releasing the connection between the scraper 5 and the connecting seat 4. The connection allows the scraper 5 to quickly detach from the connecting seat 4, facilitating the replacement of the connecting seat 4. After replacement, the scraper 5 is reinstalled. At this point, the bolt rod 601 can be rotated again to push the limiting block 602 to move axially. Since one end of the outer wall of the limiting block 602 is inclined, the inclined end provides better connection force between the scraper 5 and the connecting seat 4. When the tool holder 2 is rotated to reset, the bottom of the mating block 603 contacts the side arc-shaped outer wall of the mating rod 605, providing a lateral pushing force to the mating rod 605. Under the action of the spring 606, the mating rod 605 automatically engages with the side groove of the mating block 603, completing the automatic engagement and limiting of the tool holder 2 and the base 1. Compared with bolt fixing, this structure is more convenient to operate, facilitates the quick replacement and installation of the scraper 5, and further improves work efficiency.

[0031] Please refer to this carefully. Figures 1-3 The side groove of the docking block 603 matches the side outer wall of the docking rod 605. The side outer wall of the docking rod 605 has an arc-shaped structure. The inner wall of the base 1 is formed with a sliding groove for the axial movement of the movable rod 604.

[0032] In this embodiment: This structure provides space for the axial movement of the movable rod 604, and the arc-shaped outer wall of the docking rod 605 causes the tool holder 2 to rotate and drive the docking block 603 to reset through the through-hole, so that the bottom of the docking block 603 contacts the arc-shaped outer wall of the docking rod 605 and gives the docking rod 605 a lateral moving thrust, so that the docking rod 605 automatically engages with the side groove of the docking block 603 under the action of the spring 606.

[0033] Please refer to this carefully. Figures 1-3 The end of the scraper 5 is formed with a hole for the insertion of the limiting block 602, and one end of the outer wall of the limiting block 602 is inclined, so that the inclined end can better provide the connection force between the scraper 5 and the connecting seat 4.

[0034] In this embodiment: through this structure, when the limiting block 602 moves with the rotation of the bolt rod 601, the inclined surface at the end of the limiting block 602 will contact the end hole groove of the scraper 5 and give the scraper 5 an upward pressing force, so that the scraper 5 and the connecting seat 4 are more tightly connected.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
