[0039] Example

[0040] A quick-release constant temperature starching bucket, such as Figure 1 As shown, it includes: a frame 1, a constant temperature paddle bucket 2 and an extrusion assembly 3, the frame 1 is used to fix the constant temperature paddle bucket 2 and the extrusion assembly 3, and a disassembly port is provided on one side of the frame 1, and the constant temperature paddle bucket 2 can enter and exit the frame 1 along the disassembly port, and after entering the frame 1, it is detachably connected to the frame 1 for easy disassembly, and it is used for slurrying the electrode sheet; the extrusion assembly 3 is arranged above the outlet end of the constant temperature paddle bucket 2, and its end is detachably connected to the frame 1 for squeezing excess slurry.

[0041] like Figure 2 As shown, the frame 1 includes a side panel 11, a fixed seat 12 and a belt-entry roller 13. The side panel 11 is provided with a through hole for accommodating the constant temperature paddle bucket 2 to pass through. A pair of the side panels 11 are arranged at intervals on the top of the fixed seat 12 along the disassembly and assembly direction of the constant temperature paddle bucket 2; the belt-entry roller 13 is arranged between the pair of side panels 11 and above the belt-entry end of the constant temperature paddle bucket 2, and is rotatably connected to the side panel 11.

[0042] like Figure 3 and Figure 4 As shown, the fixing seat 12 is provided with a front positioning plate 14 and a side positioning plate 15. A pair of the front positioning plates 14 are arranged between the pair of side plates 11 and on both sides of the disassembly direction of the constant temperature paddle bucket 2. The spacing between the pair of front positioning plates 14 is the same as the width of the constant temperature paddle bucket 2. The side positioning plate 15 is arranged between the pair of front positioning plates 14 and is connected to the pair of front positioning plates 14 away from the disassembly opening. A positioning and installation area of ​​the constant temperature paddle bucket 2 is formed between the pair of front positioning plates 14 and the side positioning plates 15.

[0043] In this embodiment, a pressure code 16 connected to the fixing seat 12 is provided on one side of the front positioning plate 14 for fixing the thermostatic hopper 2 after installation to prevent displacement during use and affect normal production.

[0044] In this embodiment, the front positioning plate 14 is provided with a protruding section at the end that first contacts the thermostatic paddle 2 , and the protruding section is provided with a guiding mechanism to facilitate the rapid installation of the thermostatic paddle 2 .

[0045] In this embodiment, the fixing seat 12 is further provided with a wheel avoidance hole 17 and a ground anchor assembly 18. The wheel avoidance hole 17 is located below the constant temperature paddle bucket 2. The two pairs of the wheel avoidance holes 17 are staggered and arranged. The spacing between the pair of wheel avoidance holes 17 at the end that first enters the frame 1 is smaller than the spacing between the pair of wheel avoidance holes 17 at the end that enters the rear end, so as to facilitate the rapid positioning and installation of the constant temperature paddle bucket 2. The wheel avoidance hole 17 has an inclined surface toward the pulling side, which is convenient for the adapter structure to enter and detach from the wheel avoidance hole 17, and after being in place, the adapter structure is suspended in the air without affecting the positioning accuracy. The ground anchor assembly 18 is arranged at the four corners of the fixing seat 12, which is used to fix the frame 1, and the height can also be adjusted to adapt to the adjustment of horizontality and parallelism.

[0046] like Figures 5 to 7 As shown, the constant temperature pulp bucket 2 includes a bucket body 21, a sizing roller 22 and an impeller 23. The height from the belt inlet end to the belt outlet end of the bucket body 21 gradually decreases, and the lowest point is arc-shaped. A plurality of groups of heating devices 24 are arranged below the bucket body 21. The plurality of groups of heating devices 24 are staggered so that the slurry is evenly heated. The heating devices 24 maintain a constant temperature of the slurry in the bucket body 21 to prevent the slurry in the bucket from cooling and solidifying too quickly, so as to save the slurry. The sizing roller 22 is arranged in the middle of the bucket body 21. It is rotatably connected to the bucket body 21 through a bearing seat 25. An oil seal is used between the bearing seat 25 and the sizing roller 22. The screw holes at the bottom of the bearing seat 25 are sealed with an O-ring to prevent leakage and to facilitate adjustment of the parallelism of the sizing roller 22. The impeller 23 is arranged at the lowest position of the belt outlet end in the bucket body 21, and its input end is connected to the output end of the first driving mechanism 26 outside the bucket body 21 to prevent the bottom slurry from settling, which is beneficial to uniform stirring of the slurry and can work normally even with less slurry.

[0047] like Figure 8 As shown, a pulley 27 corresponding to the wheel avoidance hole 17 is also provided below the bucket body 21 to facilitate the pushing in and out of the constant temperature paddle bucket 2, prevent the bottom from excessively wearing out and save effort.

[0048] In this embodiment, the bucket body 21 is also provided with a handle to facilitate pushing in and out the constant temperature pulp bucket 2.

[0049] like Fig. 9As shown, the extrusion assembly 3 includes an extrusion roller 31, a mounting plate 32 and a scraper 33. A pair of the extrusion rollers 31 are arranged above the strip outlet end of the thermostatic pulp bucket 2, and their ends are rotatably connected to the frame 1; the mounting plate 32 is arranged above the extrusion rollers 31, and its ends are connected to the frame 1. It is provided with a strip-through hole at a position corresponding to the gap between the pair of extrusion rollers 31; a pair of the scrapers 33 are arranged above the mounting plate 32 and on both sides of the strip-through hole. A synchronous wheel 34 and an adjusting knob 35 are arranged at the end of the extrusion roller 31, and its input end is connected to the output end of the second driving mechanism 36 outside the frame 1. The second driving mechanism 36 simultaneously drives the synchronous wheels 34 on the two extrusion rollers 31 through a double-sided toothed synchronous belt, so that the extrusion rollers 31 rotate relatively. The adjusting knob 35 is used to adjust the spacing between the pair of extrusion rollers 31 or between the extrusion roller 31 and the sizing roller 22.

[0050] In this embodiment, a flow blocking groove is further provided at the end of the squeezing roller 31, which is used to prevent the slurry on the roller surface of the squeezing roller 31 from flowing along the step on the shaft to the sealing ring. A material blocking plate is also provided between the end of the squeezing roller 31 and the bearing seat 25.

[0051] like Fig.10 and Fig.11 A digital differential ruler 37 is provided on the side of the scraper 33 away from the belt-passing hole. The digital differential ruler 37 is connected to the mounting plate 32. The digital differential ruler 37 is connected to the scraper 33 through a spring 38. The measuring end of the digital differential ruler 37 abuts against the scraper 33. The spring 38 ensures that the scraper 33 is always close to the contact of the digital differential ruler 37 to prevent the generation of gaps and inaccurate positioning.

[0052] When the utility model is in use, the mesh belt passes around the sizing roller 22 from the upper side of the belt-entering roller 13, passes through the slit between the two squeezing rollers 31, passes through the belt-passing hole of the mounting plate 32, and then passes through the gap formed by the two scrapers 33 to vertically enter the oven placed just above the sizing component.

[0053] The utility model adopts a modular design, and the upper slurry bucket is split and designed into a frame 1, a constant temperature slurry bucket 2 and an extrusion assembly 3. The constant temperature slurry bucket 2 and the extrusion assembly 3 are fixed by the frame 1. The constant temperature slurry bucket 2 can quickly enter and exit the frame 1 through a disassembly and assembly port, and is quickly positioned and fixedly connected with the frame 1 through a front positioning plate 14, a side positioning plate 15 and a pressing code 16, thereby realizing rapid removal and positioning of the constant temperature hopper and improving work efficiency.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
