Description

Technical Field

[0001] This utility model relates to the field of scraper technology, and in particular to a scraper holder and a scraper device. Background Technology

[0002] In the manufacturing of lithium batteries, rollers are often used to roll the negative electrode sheet. During the rolling process, the negative electrode material adheres to the rollers, so a scraper is needed to remove the excess material. Existing scrapers are mostly fixed by two mounting plates and a large number of bolts. When replacing the blades, the two mounting plates must be removed from the equipment, and then the bolts must be unlocked to remove the blades. The blade replacement process is complicated and time-consuming. Moreover, when the bolts are tightened again after the blades are replaced, the blades may move due to contact or other reasons, resulting in a slight deviation in the installation position of the blades before and after the replacement. This makes it impossible to remove the excess material from the rollers. Therefore, the blade replacement operation requires highly experienced personnel, which increases the difficulty of blade replacement to some extent. Utility Model Content

[0033] To better understand the aforementioned objectives, features, and advantages of this utility model, the disclosed solutions will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments disclosed in the present invention, and not all of them.

[0035] like Figures 1-3As shown, the scraper holder in this embodiment includes: a first fixing frame 1, a second fixing frame 2, an elastic element 3, and a connecting element 4. The first fixing frame 1 and the second fixing frame 2 are rotatably connected by the connecting element 4, which is a connecting shaft. A groove 10 for clamping the scraper 100 is formed between the first fixing frame 1 and the second fixing frame 2. The elastic element 3 is installed between the first fixing frame 1 and the second fixing frame 2 and can provide a continuous elastic force to drive the first fixing frame 1 and the second fixing frame 2 to abut against each other, so that the scraper 100 can be firmly clamped in the groove 10. When the scraper needs to be replaced, the first fixing frame 1 or the second fixing frame 2 is pressed, and the first fixing frame 1 and the second fixing frame 2 rotate relative to each other, allowing the scraper 100 to slide out of the groove 10. After the scraper is replaced, the pressing of the first fixing frame 1 or the second fixing frame 2 is released, and the first fixing frame 1 and the second fixing frame 2 return to their original positions under the elastic force of the elastic element 3, and the scraper 100 is firmly fixed in the groove 10 again. The tool groove 10 effectively limits the position of the scraper 100, ensuring that the position of the scraper 100 remains unchanged before and after tool change, thus guaranteeing the installation accuracy of the scraper 100 and improving machining quality. The first fixed frame 1 and the second fixed frame 2 are rotatably connected, allowing for quick tool change with just a light press and rotation each time. Under the elastic force of the elastic element 3, the scraper 100 can be tightly clamped and positioned within the tool groove 10, eliminating the need for additional bolts or other fasteners to fix the scraper 100, shortening tool change time and improving tool change efficiency.

[0036] It is worth noting that in this embodiment, the knife groove 10 is only provided on the first fixing frame 1, and the side of the second fixing frame 2 facing the first fixing frame 1 is a planar structure. Alternatively, the knife groove 10 can be provided only on the second fixing frame 2 or on both the first fixing frame 1 and the second fixing frame 2. Both methods can achieve the above-mentioned technical effects. Any arrangement of the knife groove 10 falls within the protection scope of this application.

[0037] Specifically, such as Figures 2-4 As shown, in this embodiment, a plurality of first connecting ears 11 and a plurality of first clearance grooves 12 are provided on the side of the first fixed frame 1 facing the second fixed frame 2, and a plurality of second connecting ears 21 and a plurality of second clearance grooves 22 are provided on the side of the second fixed frame 2 facing the first fixed frame 1. The adapter 4 passes through the first connecting ears 11 and the second connecting ears 21. The first connecting ears 11 extend into the second clearance grooves 22, and the second connecting ears 21 extend into the first clearance grooves 12. The first clearance grooves 12 and the second clearance grooves 22 provide clearance space for the second connecting ears 21 and the first connecting ears 11, respectively, to prevent motion interference. In this embodiment, the rotational connection between the first fixed frame 1 and the second fixed frame 2 is realized through the adapter 4, the first connecting ears 11 and the second connecting ears 21, making the rotation between the first fixed frame 1 and the second fixed frame 2 more reliable and stable.

[0038] Optionally, the elastic element 3 in this embodiment can be a spring or a torsion spring. When the elastic element 3 is a spring, such as... Figure 2 and Figure 3 As shown, the spring and the blade groove 10 are respectively located on opposite sides of the adapter 4. That is, the spring is located on one side of the first fixing frame 1 and the second fixing frame 2, and the blade groove 10 is located on the other side of the first fixing frame 1 and the second fixing frame 2. The adapter 4 is located in the area between the elastic member 3 and the blade groove 10. A receiving groove 20 is formed between the first fixing frame 1 and the second fixing frame 2. The spring is placed in the receiving groove 20 and is always in a compressed state. One end of the spring is tightly pressed against the first fixing frame 1, and the other end is tightly pressed against the second fixing frame 2. The spring can elastically push against the first fixing frame 1 and the second fixing frame 2 so that the scraper 100 can be tightly clamped in the blade groove 10. In addition, except for the attached figure of this embodiment Figure 2 and Figure 3 In addition to the form shown, the elastic element 3 can also be a torsion spring, which is fitted onto the adapter 4. Its two ends are respectively connected to the first fixing frame 1 and the second fixing frame 2, which can also achieve the above purpose. It can be designed and selected according to the actual situation. The specific assembly method of the torsion spring can refer to the existing technology. This embodiment will not elaborate on this.

[0039] Furthermore, to increase the smoothness of rotation between the first fixed frame 1 and the second fixed frame 2, the scraper holder in this embodiment also includes a bearing component 5, such as... Figure 4 As shown (in conjunction with reference) Figure 3 The bearing component 5 is mounted on the adapter 4. The second connecting ear 21 has a bearing groove 30 that can accommodate the bearing component 5, and the bearing component 5 can be installed in the bearing groove 30. In addition, a bearing groove 30 can also be added to the first connecting ear 11 to increase the number of bearing components 5 used and ensure smooth rotation between the first fixing frame 1 and the second fixing frame 2.

[0040] Furthermore, such as Figure 2 As shown, a connecting shaft 13 is fixedly installed on the first fixed frame 1. The connecting shaft 13 is integrally formed with the first fixed frame 1. The entire scraper frame can be rotatably installed in a designated position through the connecting shaft 13, which makes the entire scraper frame rotatable and enriches the application scenarios of the scraper frame.

[0041] In addition, this embodiment also provides a scraper device, such as Figures 5-9 As shown, the scraper device includes a scraper 100, a frame body 7, and the aforementioned scraper holder. The scraper holder is mounted on the frame body 7, and the scraper 100 is mounted on the scraper holder and clamped and fixed between the first fixed frame 1 and the second fixed frame 2. This scraper device facilitates scraper replacement, reduces the difficulty of scraper replacement, shortens downtime for scraper replacement, and improves production efficiency.

[0042] Furthermore, such as Figures 5-8As shown, the scraper assembly includes a scraper holder rotation mechanism 6 and a scraper pressing mechanism 8. When the scraper 100 needs to be replaced, the scraper holder rotation mechanism 6 drives the scraper holder to the scraper changing position, as shown. Figure 8 As shown, at this time, the scraper holder is rotated as a whole, and the scraper 100 is in a horizontal position. The pressing mechanism 8 then activates to press down the scraper holder, allowing relative rotation between the first fixed frame 1 and the second fixed frame 2, enabling the scraper 100 to disengage from between them. After the scraper replacement is completed, the pressing mechanism 8 lifts back to its original position, and the scraper 100 is re-clamped between the first fixed frame 1 and the second fixed frame 2. The scraper holder rotation mechanism 6 then drives the scraper holder to rotate back to the scraper working position. Figure 7 As shown, when the scraper 100 is in the scraper working position, the scraper 100 has a certain angle with the horizontal direction so that the scraper 100 can better flatten against the roller surface. The selection of the scraper working position is related to the optimal angle position of the scraper 100 in the actual operation process, and can be adjusted according to the actual situation, including but not limited to the angle size shown in the attached figure of this embodiment. Furthermore, since the scraper frame in this embodiment is rotatably connected to the machine frame body 7 through the connecting shaft 13 on the first fixed frame 1, the downward movement of the first fixed frame 1 is restricted. Therefore, it is preferable to flip the second fixed frame 2 above the first fixed frame 1 and press down on the second fixed frame 2, preferably pressing the side of the second fixed frame 2 away from the scraper 100, so that the first fixed frame 1 and the second fixed frame 2 rotate relative to each other to complete the scraper change.

[0043] Optionally, such as Figure 5 As shown (in conjunction with reference) Figure 2 In this embodiment, the blade holder rotation mechanism 6 includes a first drive device 61, a rack 62, and a gear 63. A first fixed frame 1 is rotatably mounted on the machine frame body 7 via a connecting shaft 13. The gear 63 is mounted on the connecting shaft 13 and meshes with the rack 62. The output end of the first drive device 61 is connected to the rack 62. When the output end of the first drive device 61 reciprocates, it drives the rack 62 to move, allowing the blade holder to rotate around the connecting shaft 13, thus achieving the flipping of the blade holder. In this embodiment, the first drive device 61 is a linear output motor. In addition to the above method, the first drive device 61 can also be a rotary motor, with its rotary output end directly connected to the connecting shaft 13, driving the entire blade holder to rotate by directly driving the connecting shaft 13.

[0044] Furthermore, such as Figure 9 As shown, the blade holder rotation mechanism 6 also includes a slide rail 64, which is mounted on the frame body 7. A slider 621 is correspondingly mounted on the rack 62. The slider 621 is slidably connected to the slide rail 64 so that the rack 62 can move stably in a straight line, thereby achieving stable rotation of the blade holder.

[0045] Optionally, such as Figures 5-8As shown, the knife pressing mechanism 8 includes a second driving device 81 and a pressing block 82. The second driving device 81 is a linear motor, and the pressing block 82 is connected to the output end of the second driving device 81. When the scraper frame rotates to the scraper changing position, the second driving device 81 drives the pressing block 82 to move and press down on the second fixed frame 2, so that the second fixed frame 2 and the first fixed frame 1 rotate relative to each other, thus completing the knife changing.

[0046] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0047] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
