Description

Technical Field

[0001] This utility model relates to the field of adhesive scraping technology, specifically to an adhesive scraping assembly. Background Technology

[0002] The squeegee coating process is a key step in industries such as composite material winding, coating, lamination, and printing. The performance of its core component, the squeegee assembly, directly affects the consistency and uniformity of the coating thickness and product quality. Traditional squeegee assemblies typically consist of a squeegee shaft with a squeegee blade and bearing seats supporting both ends. In practical applications, existing squeegee assemblies have the following main shortcomings: (1) When replacing the worn scraper blade, it is necessary to first remove the bearing seat cover or multiple fastening bolts before the scraper shaft can be taken out as a whole. This process is tedious and time-consuming, and the labor intensity is high, resulting in excessive downtime of the equipment and seriously affecting production efficiency.

[0003] (2) Traditional structures have insufficient axial limit on the scraper shaft, often relying only on simple retaining rings or screws for tightening. During long-term operation of the equipment, the scraper shaft is prone to slight axial and radial movement. This movement will directly change the relative position between the scraper and the substrate, resulting in uneven scraping pressure, which in turn causes coating thickness fluctuations, scratches and other quality problems, making it difficult to guarantee the product qualification rate.

[0004] (3) The various components of the scraper assembly, such as the bearing housing and locking mechanism, are usually installed independently on the equipment frame. There is a lack of a unified installation benchmark. This means that during installation and debugging, it is necessary to make repeated adjustments to ensure the horizontality, parallelism, axial and radial position of the scraper shaft, which is time-consuming, laborious, and difficult to guarantee accuracy.

[0005] Therefore, we need to make technical improvements to the existing glue scraping mechanism to meet production needs. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a quick-replaceable and quick-locking adhesive scraper assembly that addresses the shortcomings of the existing technology.

[0007] The technical problem to be solved by this utility model is achieved through the following technical solution: a scraper assembly, which includes a scraper shaft on which a scraper blade is mounted, and bearing seats are mounted at both ends of the scraper shaft. Upper limit seats are provided on both sides of the bearing housings, and quick clamps are installed on the upper limit seats. The clamping end of the quick clamps is located directly above the bearing housing. A locking block is fixed on the end face of one end of the scraper shaft. A bracket is provided on both sides of the locking block. A locking element is provided on the bracket, the end of which can abut against the two sides of the locking block to clamp the locking block. A mounting bracket is provided on the side of the locking block, and a measuring element is mounted on the mounting bracket. The measuring contact of the measuring element abuts against one side of the locking block facing the locking element.

[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: In the above-described adhesive scraping assembly, the bottom surface of the upper limit seat forms an installation plane I that is fixed to the outer shell of the external adhesive scraping device.

[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned scraper assembly has symmetrically arranged brackets on both sides of the locking block. The brackets have an installation plane II that is perpendicular to the axis of the scraper shaft and is used to fix the scraper equipment housing. The installation planes II of the two brackets are coplanar.

[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned scraper assembly has a mounting plane Ⅲ on the mounting bracket that is perpendicular to the axis of the scraper shaft and is used to fix it to the outer shell of the scraper equipment. The mounting plane Ⅱ and one of the mounting planes Ⅲ are coplanar.

[0011] The technical problem to be solved by this utility model can also be achieved through the following technical solution: in the above-mentioned adhesive scraping assembly, the axis of the measuring contact of the measuring element is perpendicular to the axis of the adhesive scraping shaft.

[0012] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the measuring element of the adhesive scraping assembly described above is a digital dial indicator.

[0013] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned scraper assembly has a scraper mounting plane on the scraper shaft, the scraper mounting plane is parallel to the axis of the scraper shaft, a number of bolt holes are spaced apart on the scraper mounting plane, and a number of mounting grooves that cooperate with the bolt holes are opened on the scraper plate. The scraper is fixed on the scraper mounting plane of the scraper shaft by bolts that pass through the mounting grooves and are screwed into the bolt holes.

[0014] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the mounting groove of the adhesive scraping assembly described above is a waist-shaped groove.

[0015] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the adhesive scraping assembly described above, wherein the bracket is provided with a screw hole, and the locking component is a knurled high head screw; The knurled head screw abuts against the side of the locking block through the screw hole.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are: (1) The quick clamps set directly above the bearing housing can be used to instantly loosen or lock the bearing housing, so that the entire scraper shaft can be quickly lifted or lowered without the use of tools, minimizing the working time of replacing the scraper shaft. In addition, the scraper plate is provided with a waist-shaped groove, which can be easily adjusted or replaced after loosening the bolt fasteners. When replacing the scraper plate, it is only necessary to place the new scraper plate on the scraper plate mounting plane of the scraper shaft, without complicated installation and alignment, saving time and effort.

[0017] (2) The locking block and the locking parts on both sides of the bracket together form a locking mechanism for locking the locking block. By symmetrically tightening the locking parts on both sides, the axial position of the scraper shaft can be locked, which fundamentally eliminates the possible axial movement of the scraper shaft during equipment operation, solves the problems of uneven scraping, leakage or overflow caused by the insecure axial positioning of the scraper shaft, and ensures the stability of product quality.

[0018] (3) The measuring contact of the measuring element is directly pressed against the side of the locking block. Since the locking block is fixed to the scraper shaft, the tiny radial displacement of the scraper plate will be displayed in real time by the digital dial indicator, which maximizes the quality of the scraping operation. Factory staff can intuitively observe the data on the digital dial indicator and selectively adjust the scraper shaft accordingly, which changes the outdated method of relying on manual experience and manual measurement after the machine stops.

[0021] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0022] Example 1, referring to Figure 1-3 A scraper assembly includes a scraper shaft 2 on which a scraper blade 1 is mounted. The scraper blade 1 is formed into a generally square plate structure, and bearing seats 3 are mounted at both ends of the scraper shaft 2. Upper limit seats 4 are provided on both sides of the two bearing seats 3. The upper limit seats 4 are square structures. The bottom surface of the upper limit seats 4 forms an installation plane I that is fixed to the outer shell of the external scraping equipment. The outer shell of the external scraping equipment (not shown in the figure) is actually a flat metal shell. It can be installed with bolt fasteners. A quick clamp 5 is installed on the upper limit seats 4. The quick clamp 5 is existing technology and can be selected according to the usage requirements. The clamping end of the quick clamp 5 is located directly above the bearing seat 3. The quick clamp 5 is designed to press the top outer peripheral surface of the bearing seats 3 at both ends of the scraping shaft 2. A locking block 6 is fixedly provided on the end face of one end of the scraper shaft 2. The locking block 6 is formed into a roughly square block structure. It is sleeved on the outer circumferential surface of one end of the scraper shaft 2 and located outside the bearing seat 3. Supports 7 are provided on both sides of the locking block 6. The supports 7 are formed into square supports 7. The supports 7 are provided with screw holes. The supports 7 are symmetrically arranged on both sides of the locking block 6. The supports 7 have an installation plane II that is perpendicular to the axis of the scraper shaft 2 and is used to fix it to the outer shell of the scraper equipment. It can be installed to the outer shell of the scraper equipment by bolt fasteners. The installation plane II of the two supports 7 are coplanar. The supports 7 are provided with locking parts 8 whose ends can abut against the two sides of the locking block 6 to clamp the locking block 6. The locking parts 8 are knurled high head screws. The knurled high head screws abut against the side of the locking block 6 through the screw holes. The purpose of the two supports 7 and the locking parts 8 is to fix and clamp the locking block 6 to keep the scraper shaft 2 in a fixed state. A mounting bracket 9 is provided on the side of the locking block 6. The mounting bracket 9 is formed into a square frame. The mounting bracket 9 has a mounting plane Ⅲ that is perpendicular to the axis of the scraper shaft 2 and is used to fix it to the outer shell of the scraper equipment. The mounting plane Ⅱ and one of the mounting planes Ⅲ are coplanar. A measuring element 10 is mounted on the mounting bracket 9. The measuring contact of the measuring element 10 abuts against one side of the locking block 6 facing the locking member 8. The axis of the measuring contact of the measuring element 10 is perpendicular to the axis of the scraper shaft 2. The measuring element 10 is a digital dial indicator.

[0023] In Example 1, the purpose of the measuring element 10 is to detect whether there is a wobbling displacement between the scraper shaft 2 and the scraper plate 1. This is because the scraper plate 1, due to being in a glue-coating state for a long time, will generate a certain pressure at its end. This pressure will cause the scraper plate 1 and the scraper shaft 2 to swing away from the glue. If this slight wobbling is not adjusted in time, it will affect the quality of the scraping. Since the measuring contact of the measuring element 10 is facing the side of the locking block 6, when the scraper shaft 2 and the scraper plate 1 swing together, it will also drive the locking block 6, which is fixed as one piece, to swing. This will cause the locking block 6 to move closer to or further away from the measuring contact of the measuring element 10. Therefore, the measuring value of the measuring element 10 will change at this time, and the operator can then make further adjustments based on the change in value.

[0024] Example 2, a scraper assembly as described in Example 1, wherein the scraper shaft 2 has a scraper mounting plane 11, which is parallel to the axis of the scraper shaft 2. A plurality of bolt holes are spaced apart on the scraper mounting plane 11, and a plurality of mounting grooves 12 that cooperate with the bolt holes are provided on the scraper plate 1. The mounting grooves 12 are waist-shaped grooves, and the scraper is fixed on the scraper mounting plane 11 of the scraper shaft 2 by bolts that pass through the mounting grooves 12 and are screwed into the bolt holes.

[0025] The adhesive scraper assembly in Examples 1-2 is used as follows: First, the bearing seats 3 at both ends of the scraper shaft 2 need to be placed on the top of the scraper equipment housing. Generally, the top of the scraper equipment will have a pair of U-shaped grooves (not shown in the figure) for holding the bearing seats 3. Then, we fix the upper limit seat 4 on the scraper equipment housing next to the mounting groove. At this time, the mounting plane I is close to the scraper equipment housing, so that when the quick clamp 5 is in the clamping state, it can press the bottom outer circumference of the bearing seat 3. When placing the scraper shaft 2, keep the locking block 6 tilted downward as much as possible. Then fix the two brackets 7 symmetrically on the scraper equipment housing on both sides of the locking block 6. At this time, the mounting plane II of the two brackets 7 is also close to the scraper equipment housing. The initial placement of the upper limit seat 4, scraper shaft 2 and mounting bracket 9 is completed. After the initial installation is completed, the working angle of the scraper shaft 2 and the scraper blade 1 on it needs to be further adjusted. After the angle is adjusted, the operator tightens the two knurled head screws on the bracket 7 symmetrically so that their ends are firmly pressed against both sides of the locking block 6, and finally locks the axial position of the scraper shaft 2 to completely eliminate any possible movement. At this time, the measuring contact of the digital dial indicator is pressed against the side of the locking block 6, and the operator can set its reading to zero and use this as a reference. During normal operation of the equipment, the operator can directly observe the real-time reading of the digital dial indicator. As the scraper blade 1 scrapes the glue, the scraper shaft 2 is prone to slight radial displacement or slight rotation. This may be an error in the clamping force of the knurled high head screw, or an error generated during the scraping operation. This displacement will be transmitted to the dial indicator through the locking block 6 and displayed directly in digital form. The operator can observe this intuitively and take further measures. When it is necessary to replace scraper blade 1, we only need to remove the bolts and fasteners on scraper blade 1, and then place the new scraper blade 1 on the scraper mounting plane 11 of scraper shaft 2. Because scraper blade 1 has a waist-shaped groove, the position of scraper blade 1 on scraper mounting plane 11 can be adjusted according to the usage requirements. After adjustment, it can be locked with bolts and fasteners.
