Description

Technical Field

[0001] This utility model relates to the technical field of scraper connecting devices, specifically a scraper connecting device. Background Technology

[0002] With the widespread use of film transfer sizing machines, the scraper used in these machines has become an important production spare part, which often needs to be replaced based on factors such as service life, type of paper being produced, and appearance quality.

[0003] For example, the quick connection device for papermaking film sizing and coating machine scraper, as announced in CN2679222Y, includes a universal joint, spline external teeth, spline internal teeth, locking cap, and sizing rod. When connecting, the spline internal and external teeth mesh, and then the locking cap locks the connection for normal operation. This connection method makes it quick and easy to replace the sizing rod, ensures smooth operation of the sizing rod, and improves the service life of the sizing rod.

[0004] Traditional scrapers use support frames at both ends, with copper sleeves clamping the scraper onto the support frames. The copper sleeves rotate with the scraper. Fixing the copper sleeves is relatively more troublesome during installation, and the copper sleeves are consumable parts that need to be replaced regularly, which increases both workload and maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to provide a scraper connecting device to solve the problems mentioned in the background art, which is that the traditional scraper uses support clamps at both ends and a copper sleeve to clamp the scraper to the support frame. The copper sleeve rotates with the scraper, and fixing the copper sleeve is relatively more troublesome during the installation process. In addition, the copper sleeve is a vulnerable part that needs to be replaced regularly, which increases both the workload and the maintenance cost.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scraper connecting device, comprising a quick-connect connector and a connecting plate, wherein a connecting block a is provided on one side of the quick-connect connector, and a connecting flange is rotatably connected to one side of the connecting block a via a universal joint a, and one side of the connecting flange is fixed to a scraper motor by bolts; two sets of self-locking knobs are rotatably connected to the outer side of the quick-connect connector, and multiple sets of rotating shafts are rotatably connected between the two sets of self-locking knobs via rotating shafts, a limiting mechanism for limiting the self-locking knobs is provided on one side of the rotating shafts, and a connecting plate is fixedly connected to one side of the self-locking knobs by screws, and a fixing mechanism for fixing the inserted scraper is provided on the inner side of the connecting plate; a telescopic mechanism for movement is provided between the quick-connect connector and the connecting block a.

[0007] Furthermore, the limiting mechanism includes a spring piece that is rolled to the outside of the rotating shaft, one side of which is fixed to the outside of the quick-connect connector, and a reset groove matching the spring piece is provided on the inner side of the self-locking knob.

[0008] Furthermore, the reset groove is inclined, a bolt is provided on one side of the reset groove, and one end of the bolt is threadedly connected to a quick-connect connector, and the outer side of the bolt abuts against the rotating shaft.

[0009] Furthermore, the fixing mechanism includes a spline groove a inside the connecting plate, and a spline groove b inside the quick connector, wherein the spline groove b has the same size and number of teeth as the spline groove a.

[0010] Furthermore, the telescopic mechanism includes a connecting sleeve rotatably connected to one side of the quick-connect connector via a universal joint b. The connecting sleeve has a rectangular groove inside, and a connecting block b is slidably connected to the inner side of the rectangular groove. The connecting block b is rectangular in shape, and a connecting rod is fixedly connected to one end of the connecting block b.

[0011] Furthermore, one end of the connecting rod is fixed to the connecting block a, and the end of the connecting sleeve is threadedly connected to a threaded sleeve. The end of the threaded sleeve has a circular hole for the connecting rod to slide, and the size of the circular hole is smaller than the size of the connecting block b. The connecting block b and the connecting sleeve form a sliding structure, and the connecting sleeve and the threaded sleeve form a threaded transmission structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the scraper connecting device can align the internal spline groove a with the spline groove b by rotating the self-locking knob. Then, the connecting device can be moved by the telescopic mechanism so that the scraper is inserted into the spline groove b. Subsequently, the self-locking knob can be rotated to reset, so that the spline groove a and spline groove b in the self-locking knob are misaligned, thus completing the limiting installation of the scraper. At the same time, the limiting mechanism can limit the self-locking knob.

[0013] 1. Rotate the self-locking knob until the outer scale line is at the OFF mark. At this time, the spline groove a inside the self-locking knob will coincide with the spline groove b. Then, pull the quick-connect connector down so that the spline head at the end of the scraper is fully inserted into the spline groove b. Then, rotate the self-locking knob back to the ON mark. At this time, the spline groove a and spline groove b will be misaligned, thereby limiting and fixing the scraper inserted into the spline groove b and preventing it from coming off.

[0014] 2. When the telescopic mechanism is in motion, the connecting block b can slide inside the connecting sleeve. Since the round hole at the end of the threaded sleeve is smaller than the volume of the connecting block b, it can prevent it from detaching from the inside of the connecting sleeve. By rotating the threaded sleeve, the connection with the connecting sleeve can be disengaged, and then the connecting block b can be pulled out from the connecting sleeve.

[0022] 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.

[0023] Example 1: Please refer to Figures 1-3 This utility model provides the following technical solution: a scraper connecting device, including a quick-connect connector 1 and a connecting plate 6. A connecting block a2 is provided on one side of the quick-connect connector 1. A connecting flange 3 is rotatably connected to one side of the connecting block a2 via a universal joint a. One side of the connecting flange 3 is fixed to the scraper motor by bolts. Two sets of self-locking knobs 4 are rotatably connected to the outside of the quick-connect connector 1. Multiple sets of rotating shafts 5 are rotatably connected between the two sets of self-locking knobs 4 via a rotating shaft. A limiting mechanism for limiting the self-locking knobs 4 is provided on one side of the rotating shafts 5. A connecting plate 6 is fixedly connected to one side of the self-locking knobs 4 by screws. A fixing mechanism for fixing the inserted scraper is provided on the inside of the connecting plate 6. When connecting the scraper to the scraper, the scraper is first installed on the rod holder, and then the self-locking knob 4 is rotated so that the scale line on the outside of the self-locking knob 4 rotates from the ON mark on the quick-connect connector 1 to the OFF mark. When the self-locking knob 4 rotates, it will drive the multiple sets of rotating shafts 5 on the inside to rotate synchronously.

[0024] Please see Figures 3-6The limiting mechanism includes a spring 9 that is rolled on the outside of the rotating shaft 5. One side of the spring 9 is fixed to the outside of the quick connector 1. The inner side of the self-locking knob 4 is provided with a reset groove 10 that matches the spring 9. The reset groove 10 is inclined. A bolt is provided on one side of the reset groove 10, and one end of the bolt is threaded to the quick connector 1. The outer side of the bolt abuts against the rotating shaft 5. When the rotating shaft 5 rotates with the self-locking knob 4, it will squeeze the spring 9. At this time, the spring 9 will deform, and the self-locking knob 4 can continue to rotate. When the scale line on the outside of the self-locking knob 4 rotates to the OFF mark, the spline groove a7 inside the self-locking knob 4 will coincide with the spline groove b8 inside the quick connector 1.

[0025] Please see Figures 5-6 The fixing mechanism includes a spline groove a7 inside the connecting plate 6 and a spline groove b8 inside the quick-connect connector 1. The spline groove b8 has the same size and number of teeth as the spline groove a7. When the spline groove a7 and the spline groove b8 are aligned, the quick-connect connector 1 can be pulled down by the telescopic mechanism, so that the spline head at the end of the scraper passes through the spline groove a7 in the connecting plate 6 and enters the spline groove b8. After the spline head at the end of the scraper is fully inserted into the spline groove b8, the self-locking knob 4 can be rotated to reset. When the scale line on the outside of the self-locking knob 4 returns to the ON mark, the spline groove a7 and the spline groove b8 will be misaligned, thereby limiting and fixing the scraper inserted into the spline groove b8 to prevent it from coming off. At the same time, the spring 9 will be in the reset groove 10, so the spring 9 will be reset and tilted, so that the rotating shaft 5 is blocked by the spring 9 when rotating, thereby limiting the rotating shaft 5 and preventing the self-locking knob 4 from moving arbitrarily.

[0026] Please see Figures 1-2The telescopic mechanism includes a connecting sleeve 11 rotatably connected to one side of the quick-connect connector 1 via a universal joint b. The connecting sleeve 11 has a rectangular groove inside, and a connecting block b12 is slidably connected to the inner side of the rectangular groove. The connecting block b12 is rectangular in shape, and a connecting rod 13 is fixedly connected to one end of the connecting block b12. One end of the connecting rod 13 is fixed to the connecting block a2. A threaded sleeve 14 is threadedly connected to the end of the connecting sleeve 11. The end of the threaded sleeve 14 has a circular hole for the connecting rod 13 to slide through, and the size of the circular hole is smaller than the size of the connecting block b12. The connecting block b12 and the connecting sleeve 11 form a sliding structure, and the connecting sleeve 11 and the threaded sleeve 14 form a threaded transmission structure. The telescopic mechanism consists of a connecting sleeve 11 and a connecting rod a2. The device consists of a sleeve 11, a connecting block b12, a connecting rod 13, and a threaded sleeve 14. The rectangular groove inside the connecting sleeve 11 cooperates with the rectangular connecting block b12, allowing the connecting block a2 to rotate and drive the quick-connect connector 1 to rotate as well. At the same time, the connecting block b12 can slide inside the connecting sleeve 11. The round hole at the end of the threaded sleeve 14 limits the connecting block b12 to prevent it from detaching from the inside of the connecting sleeve 11. When it is necessary to disassemble the connecting block a2, the threaded sleeve 14 is rotated to engage with the threaded drive of the connecting sleeve 11 and disengage from the connecting sleeve 11. Then, the connecting block b12 can be pulled out from the connecting sleeve 11 to complete the separation. The threaded sleeve 14 can fix the extension range of the telescopic mechanism.

[0027] The above steps facilitate quick connection of the scraper.
