[0020] The application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model, and are not a limitation on the utility model. In addition, it should be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings.
[0021] The embodiment of the application provides a scraper device 100 for a textile coating machine, which is used for scraping coating on the surface of the fabric to scrape the coating to the required thickness.
[0022] Please refer to the accompanying drawings Figs. 1-3The scraper 100 device comprises a scraper 100 assembly and two damping assemblies. The scraper 100 assembly comprises the scraper 100 and a scraper 100 mounting rack. The scraper 100 is arranged on the scraper 100 mounting rack 210, which is mounted on the rack of the textile coating machine through a moving structure. The moving structure is an existing lifting structure, and the present application will not be described here. The two damping assemblies are arranged on both sides of the scraper 100 along the length direction. The transverse direction mentioned above is the length direction of the scraper 100. The damping assembly comprises a mounting rack 210 and a push tube assembly arranged on the mounting rack 210. The mounting rack 210 is used to fix the rack of the textile coating machine. That is, the damping assembly is mounted on the rack through the mounting rack 210. The damping assembly supports the scraper 100 through the push tube assembly to reduce the transverse amplitude of the scraper 100. The damping assembly comprises a hollow mounting tube 220, a hollow first push tube 230 and a second push tube 240. The mounting tube 220 is fixedly arranged on the mounting rack 210. The first push tube 230 is sleeved on the outer periphery of the mounting tube 220. The second push tube 240 is inserted into the mounting tube 220. The end of the first push tube 230 close to the scraper 100 is provided with a damping pad. The first push tube 230 and the second push tube 240 are movably arranged along the direction close to or away from the scraper 100. Among them, the two first push tubes 230 are used to transversely position the scraper 100. After the two first push tubes 230 transversely position the scraper 100, the two second push tubes 240 transversely support the scraper 100.
[0023] The use process of the damping assembly provided by the present embodiment is as follows: after the scraper 100 moves to the target position, the user first drives one of the first push tubes 230 to move towards the scraper 100 to make the first push tube 230 contact the scraper 100. The user then drives the other first push tube 230 to move towards the scraper 100 to make the first push tube 230 contact the scraper 100, so as to realize the transverse positioning of the scraper 100. Then the user drives the two second push tubes 240 to move towards the scraper 100 respectively, so that the two second push tubes 240 push the scraper 100 through the damping pad. Then the two first push tubes 230 are driven to move reversely to separate the first push tube 230 from the scraper 100. It should be understood that during the pushing of the scraper 100 by the second push tube 240, the scraper 100 has been positioned by the two first push tubes 230, so that the scraper 100 will not produce transverse displacement in this stage, thereby ensuring that the scraper 100 maintains the target position when being supported by pushing (i.e. before the scraping operation), and the transverse displacement does not occur. In addition, since the second push tube 240 contacts the scraper 100 through the damping pad, the damping pad has a damping effect, thereby reducing the impact of the scraper 100 on the second push tube 240, and improving the service life of the damping assembly 200.
[0024] Preferably, the mounting pipe 220, the first pushing pipe 230 and the second pushing pipe 240 are all circular tubes. The mounting frame 210 can be generally cylindrical.
[0025] Preferably, the mounting pipe 220 is arranged in parallel with the length direction of the scraper 100, and the axes of the two mounting pipes 220 are coincident.
[0026] In some embodiments of the present application, the second pushing pipe 240 has a first end close to the scraper 100, and the first end extends out of the mounting pipe 220. The first end is provided with a locking member 270 movably arranged to switch between a locked position and an unlocked position. In the locked position, the locking member 270 is in abutting engagement with the mounting pipe 220 to avoid the second pushing pipe 240 from moving reversely under the vibration impact of the scraper 100, thereby improving the support stability of the second pushing pipe 240 to the scraper 100. In the unlocked position, the abutting engagement between the locking member 270 and the mounting pipe 220 is released, so that the second pushing pipe 240 can move away from the scraper 100 to release the pushing effect of the second pushing pipe 240 to the scraper 100.
[0027] Preferably, in the unlocked position, the locking member 270 is arranged separately from the mounting pipe 220.
[0028] Preferably, the outer periphery of the second pushing pipe 240 is provided with external threads, the inner surface of the mounting pipe 220 is provided with internal threads, the second pushing pipe 240 is screwed with the mounting pipe 220, and the locking member 270 is a locking nut which is sleeved on the outer periphery of the first end and screwed with the first end. The inner surface of the first pushing pipe 230 is provided with internal threads, the outer periphery of the mounting pipe 220 is provided with external threads, and the first pushing pipe 230 is screwed with the mounting pipe 220. When the second pushing pipe 240 is pushed with the scraper 100, the first pushing pipe 230 is moved away from the scraper 100 to expose the end of the mounting pipe 220 close to the scraper 100, and then the user rotates the locking nut to make the locking nut abut with the end surface of the mounting pipe 220.
[0029] In some embodiments of the present application, the second pushing pipe 240 has a second end opposite to the first end, the second end extends out of the mounting pipe 220, and the second end is provided with a rotating wrench 260 which can help the user to operate the rotating movement of the second pushing pipe 240.
[0030] In some embodiments of the present application, the end surface of the second pushing pipe 240 close to the scraper 100 is concavely provided with a mounting groove, and a damping pad is mounted in the mounting groove and one end of the damping pad extends out of the mounting groove, so that the connection strength between the damping pad 250 and the second pushing pipe 240 is better.
[0031] The connection between the damping pad 250 and the second push tube 240 can be, but is not limited to, bonding and the like.
[0032] The material of the damping pad 250 can be preferably rubber. The rubber pad has good wear resistance, which improves the service life of the damping pad 250.
[0033] Preferably, a support ring 280 is embedded in the protruding end of the damping pad, the axis of the support ring 280 is arranged obliquely relative to the axis of the second push tube 240, the hardness of the support ring 280 is greater than the hardness of the damping pad, so as to reduce the torsion amplitude of the damping pad 250 and ensure the fit between the damping pad 250 and the scraper 100. The support ring 280 is preferably a metal ring, such as a steel ring and the like.
