Description

Technical Field

[0001] The utility model relates to the field of paint coatings, in particular to a scraper adjusting mechanism. Background Art

[0002] When the material passes through the rotating roller, the coating on the surface of the material needs to be evenly applied, which often requires the use of a scraper. The distance between the rotating roller and the scraper needs to be adjusted according to the coating requirements of different materials.

[0003] Conventional scraper adjustment mechanisms can only adjust the scraper up and down to adjust the spacing; however, the front-to-back adjustment of the scraper cannot meet the requirements of coating consistency.

[0004] In summary, how to achieve the lifting and lowering adjustment and front and rear adjustment of the scraper to meet the adjustment of the distance between the scraper and the rotating roller and the wrap angle has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to realize the lifting and lowering adjustment and the front and rear adjustment of the scraper;

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The utility model is a scraper adjustment mechanism, comprising: a frame; a sliding seat, which is slidably arranged on the top of the frame and is moved back and forth along the length direction of the frame by a first driving mechanism; a lifting seat, which is slidably arranged at the bottom of the sliding seat and is moved up and down along the height direction of the frame by a second driving mechanism; a support pull rod, both ends of which are provided with the lifting seats; a plurality of cylinders, whose cylinder bodies are fixed on the support pull rod at equal intervals; a fixed rod, which is vertically fixed on the support pull rod; a scraper frame, the middle portion of which is hinged to the fixed rod, one end of which is hinged to the piston rod of the cylinder, and the other end of which is fixed with a scraper;

[0008] In this solution, the first driving mechanism realizes the forward and backward movement of the sliding seat and the supporting rod relative to the frame, at which time the distance between the scraper and the rotating roller can be adjusted;

[0009] The second driving mechanism realizes the height adjustment of the lifting seat relative to the sliding seat and the supporting pull rod, and at this time, the height adjustment of the scraper relative to the rotating roller can be realized, thereby adjusting the wrap angle of the scraper;

[0010] For the angle adjustment of the scraper, this solution adopts a scraper hinged to the support rod through a fixed rod, and the piston rod of the cylinder is connected to one end of the scraper frame. When the cylinder is working, one end of the scraper frame descends, and the other end of the scraper frame drives the scraper to rise, thereby achieving the angle adjustment of the scraper;

[0011] In summary, the first drive mechanism, the second drive mechanism, and the cylinder realize the functions of the scraper moving forward and backward, lifting and lowering, and adjusting its own angle to meet the requirements of coating consistency.

[0012] To illustrate the specific structure of the first driving mechanism, the present invention adopts the first driving mechanism comprising: a first screw, which is rotatably arranged at the bottom of the frame, and its axis direction is parallel to the length direction of the frame; a first sliding nut matched with the first screw, which is fixedly connected to the sliding seat; a first rotating handwheel, the input end of the reducer is connected to the first rotating handwheel, and the output end of the reducer is connected to the end of the first screw;

[0013] The linear motion of the sliding seat is achieved through the cooperation of the first screw rod and the first sliding nut. The first screw rod and the first rotating handwheel are connected by a reducer. In this way, when the first rotating handwheel rotates one circle, the number of rotations of the screw rod decreases, and the distance moved by the first sliding nut decreases, thereby achieving fine-tuning of the scraper in the front and back directions.

[0014] To illustrate the specific structure of the second driving mechanism, the second driving mechanism adopted by the present invention includes: a second screw rod, which is rotatably arranged on the sliding seat, and its axial direction is vertically arranged; a second sliding nut matched with the second screw rod, which is fixedly connected to the lifting seat; a second rotating hand wheel, which is connected to the end of the second screw rod;

[0015] By rotating the second rotating hand wheel, the torque is transferred to the second screw rod to realize the lifting movement of the second sliding nut, thereby realizing the lifting and lowering adjustment of the lifting seat.

[0016] During the lifting and lowering adjustment process, the support rod itself will slightly float up and down due to the influence of the pitch of the second screw. In order to offset this gap, the utility model adopts a fixed locking part at the bottom of the frame; a locking rod is threadedly connected to the locking part, and its top abuts against the lifting seat;

[0017] After the height of the support rod is adjusted, the locking rod is rotated to move upward, and the top is pressed against the bottom of the support rod, so that the support rod is fine-tuned upward. In this way, the support rod will not be affected by the pitch of the second screw rod and will float slightly up and down.

[0018] The beneficial effects of the utility model are as follows: the utility model is a scraper adjustment mechanism, which realizes the functions of the scraper's forward and backward movement, lifting and lowering, and its own angle adjustment through the first drive mechanism, the second drive mechanism, and the cylinder, and adjusts the scraper to a suitable position between the scraper and the rotating roller to meet the requirements of coating consistency.

DETAILED DESCRIPTION

[0024] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0025] like Figure 1-2 As shown, the utility model is a scraper adjustment mechanism, comprising: a frame 1; a sliding seat 2, which is slidably arranged on the top of the frame 1 and is moved back and forth along the length direction of the frame 1 by a first driving mechanism; a lifting seat 3, which is slidably arranged at the bottom of the sliding seat 2 and is lifted and lowered along the height direction of the frame 1 by a second driving mechanism; a support rod 4, both ends of which are provided with the lifting seats 3; a plurality of cylinders 5, whose cylinder bodies are fixed on the support rod 4 at equal intervals; a fixed rod 6, which is vertically fixed on the support rod 4; a scraper frame 7, the middle part of which is hinged to the fixed rod 6, one end of which is hinged to the piston rod of the cylinder 5, and the other end of which is fixed with a scraper 8;

[0026] In this solution, the first driving mechanism realizes the forward and backward movement of the sliding seat and the supporting rod relative to the frame, at which time the distance between the scraper and the rotating roller can be adjusted;

[0027] The second driving mechanism realizes the height adjustment of the lifting seat relative to the sliding seat and the supporting pull rod, and at this time, the height adjustment of the scraper relative to the rotating roller can be realized, thereby adjusting the wrap angle of the scraper;

[0028] For the angle adjustment of the scraper, this solution adopts a scraper hinged to the support rod through a fixed rod, and the piston rod of the cylinder is connected to one end of the scraper frame. When the cylinder is working, one end of the scraper frame descends, and the other end of the scraper frame drives the scraper to rise, thereby achieving the angle adjustment of the scraper;

[0029] In summary, the first drive mechanism, the second drive mechanism, and the cylinder realize the functions of the scraper moving forward and backward, lifting and lowering, and adjusting its own angle to meet the requirements of coating consistency.

[0030] like Figure 2 As shown, in order to illustrate the specific structure of the first driving mechanism, the utility model adopts the first driving mechanism comprising: a first screw rod 11, which is rotatably arranged at the bottom of the frame 1, and its axial direction is parallel to the length direction of the frame 1; a first sliding nut 12 matched with the first screw rod 11, which is fixedly connected to the sliding seat 2; a first rotating hand wheel 13, the input end of the reducer 14 is connected to the first rotating hand wheel 13, and the output end of the reducer 14 is connected to the end of the first screw rod 11;

[0031] The linear motion of the sliding seat is achieved through the cooperation of the first screw rod and the first sliding nut. The first screw rod and the first rotating handwheel are connected by a reducer. In this way, when the first rotating handwheel rotates one circle, the number of rotations of the screw rod decreases, and the distance moved by the first sliding nut decreases, thereby achieving fine-tuning of the scraper in the front and back directions.

[0032] like Figure 1 As shown, in order to illustrate the specific structure of the second driving mechanism, the second driving mechanism adopted by the present invention includes: a second screw rod 21, which is rotatably arranged on the sliding seat 2, and its axial direction is vertically arranged; a second sliding nut 22 matched with the second screw rod 21, which is fixedly connected to the lifting seat 3; a second rotating hand wheel 23, which is connected to the end of the second screw rod 21;

[0033] By rotating the second rotating hand wheel, the torque is transferred to the second screw rod to realize the lifting movement of the second sliding nut, thereby realizing the lifting and lowering adjustment of the lifting seat.

[0034] like Figure 1 As shown, during the lifting and lowering adjustment process, the support rod itself will have a slight up and down float due to the influence of the second screw pitch. In order to offset this gap, the present invention adopts the fixing locking portion 31 at the bottom of the frame; the locking rod 32 is threadedly connected to the locking portion 31, and its top abuts against the lifting seat 3;

[0035] After the height of the support rod is adjusted, the locking rod is rotated to move upward, and the top is pressed against the bottom of the support rod, so that the support rod is fine-tuned upward. In this way, the support rod will not be affected by the pitch of the second screw rod and will float slightly up and down.

[0036] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
