Description

Technical Field

[0001] The utility model relates to the technical field of rubber roll scraping knife assemblies, in particular to a scraping knife assembly capable of adjusting the glue coating thickness of wine box face paper. Background Technique

[0002] A scraping knife assembly is installed on one side of a glue coating roller on a glue coating device. The scraping knife assembly includes a support shaft, a locking member for locking the support shaft, a knife seat sleeved outside the support shaft, a scraping knife fixed on the knife seat, and a fixing member installed on the knife seat for fixing the knife seat on the support shaft, such as a roller adjustable brush glue assembly disclosed in the existing publication number CN219880438U.

[0003] During actual use, when adjusting the spacing of the scraping knives, first operate the locking member to release the fixation of the support shaft, then operate the handle on the support shaft to rotate the support shaft to separate the scraping knife from the glue coating roller.

After adjusting the position of the knife seat, operate the fixing member again to position the knife seat. When adjusting multiple scraping knives simultaneously, operate multiple fixing members repeatedly in sequence. The operation is very cumbersome, and for the adjustment work of multiple knife seats, the positioning and release of multiple knife seats cannot be completed at one time.

[0004] Therefore, it is necessary to provide a scraping knife assembly capable of adjusting the glue coating thickness of wine box face paper to solve the above technical problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] Figures 1 to 7 The first implementation manner is shown: A scraper assembly for adjusting the glue coating thickness of the face paper of a wine box, comprising:

[0036] A frame 1;

[0037] A support roller 2, rotatably connected to the frame 1 through a bearing, and an adjustment handle 3 is fixed on the outer wall of the support roller 2;

[0038] A scraper seat 4, slidably connected to the outer wall of the support roller 2 through a sliding hole, and a scraper 5 is fixed on the outer wall of the scraper seat 4;

[0039] A pre-limiting module 6, arranged on the scraper seat 4, for pre-limiting the state of the scraper seat 4 on the support roller 2;

[0040] An inner pressing module 7, installed on the inner wall of the support roller 2, for simultaneously positioning all the scraper seats 4;

[0041] A locking module 8, fixed on the frame 1, for fixing the angle of the support roller 2.

[0042] The support roller 2 is composed of a left half part 201 and a right half part 202. The left half part 201 and the right half part 202 are fixed by screws. A through groove 2011 is formed in the middle of the left half part 201, and the adjustment handle 3 is fixed on the right half part 202.

[0043] The locking module 8 includes a support seat 81 fixed on the frame 1. The support roller 2 is rotatably connected to the support seat 81 through a round hole. The upper end of the support seat 81 is threadedly connected with a screw rod 82 through a first threaded hole. A knob 83 is fixed on the top of the screw rod 82. The bottom of the screw rod 82 penetrates to the inside of the support seat 81 and is in pressing contact with the outer wall of the support roller 2.

[0044] The pre-limiting module 6 includes a sleeve 61 fixed on the outer wall of the scraper seat 4. A through hole 62 is formed in the scraper seat 4 corresponding to the sleeve 61. A pressing rod 63 is slidably sleeved on the inner walls of the sleeve 61 and the through hole 62. A spring 64 is sleeved in the sleeve 61. One end of the spring 64 is in pressing contact with the inner wall of the sleeve 61, and the other end of the spring 64 is in pressing contact with the end of the pressing rod 63. The pressing rod 63 cooperates with the support roller 2.

[0045] One end of the pressing rod 63 close to the support roller 2 is fixed with a rubber pad 65, and the rubber pad 65 is in pressing contact with the outer wall of the support roller 2.

[0046] The inner pressing module 7 includes a pressing strip 71 slidably connected to the inner wall of the through groove 2011. One side of the pressing strip 71 is pressed against the inner wall of the scraper seat 4. Eccentric rollers 72 are symmetrically rotatably connected to the inner wall of the support roller 2 through bearings, and the eccentric rollers 72 are pressed against the outer wall of the pressing strip 71. Motors 73 are symmetrically fixed to the inner wall of the support roller 2, and the output ends of the motors 73 are fixed to the ends of the corresponding eccentric rollers 72.

[0047] By providing the pre-limiting module 6 and the inner pressing module 7 in this application, when it is necessary to adjust the states of multiple scrapers 5, the states of the multiple scrapers 5 can be quickly pre-limited, and then the inner pressing module 7 can be used to quickly position the states of the multiple scrapers 5, without the need to unlock, adjust, and fix each of the scrapers 5 one by one, which provides convenience for the adjustment of the scrapers 5.

[0048] Figure 8 The second embodiment is shown, and the main difference from the first embodiment is that:

[0049] The sleeve 61 includes an adjusting piece 9 slidable on the inner wall of the sleeve 61. One end of the spring 64 away from the pressing rod 63 is in pressing contact with the outer wall of the adjusting piece 9. One end of the adjusting piece 9 away from the spring 64 is fixed with a bolt 10, and the bolt 10 is threadedly connected to the sleeve 61 through a second threaded hole.

[0050] By providing the bolt 10 and the adjusting piece 9 in this application, when the spring 64 becomes fatigued after long-term use, resulting in unstable pre-limiting of the scraper 5, the bolt 10 can be rotated to move the adjusting piece 9 on the inner wall of the sleeve 61 to compensate for the fatigue of the spring 64, thereby ensuring the stability of the pre-limiting of the scraper 5, which has practicality.

[0051] Working principle:

[0052] Rotate the knob 83 to rotate the screw rod 82 within the support base 81, causing the bottom of the screw rod 82 to move away from the support roller 2. At this time, the adjusting handle 3 can be used to rotate the support roller 2, thereby driving the scraper 5 to rotate away from the rubber roller. Subsequently, drive the motor 73 to rotate the eccentric roller 72 away from the abutting strip 71. The abutting strip 71 no longer abuts against the inner wall of the scraper seat 4, and the scraper seat 4 can be moved and adjusted on the support roller 2. The spring 64 on the inner wall of the sleeve 61 presses against the abutting rod 63, causing the abutting rod 63 to closely adhere to the support roller 2, thereby pre-positioning the position of the scraper seat 4. After the adjustment of multiple scrapers 5 is completed, drive the motor 73 again to rotate the eccentric roller 72 until it presses against the abutting strip 71. The abutting strip 71 slides within the through groove 2011, so that one side of the abutting strip 71 abuts against the inner wall of the scraper seat 4 to synchronously position multiple scrapers 5. Subsequently, use the adjusting handle 3 to rotate the scraper 5 again to be close to the outer wall of the rubber roller, and rotate the knob 83 again to make the bottom of the screw rod 82 abut against the support roller 2 to position the support roller 2.

[0053] When rotating the bolt 10, the adjusting piece 9 can be driven to move within the inner wall of the sleeve 61, thereby pulling the spring 64. When the spring 64 becomes fatigued after long-term use, resulting in unstable pre-positioning of the scraper 5, the bolt 10 can be rotated to move the adjusting piece 9 within the inner wall of the sleeve 61 to compensate for the fatigue of the spring 64.
