Description

Technical Field

[0001] The utility model relates to the technical field of dry electrode preparation devices, in particular to an adjustable dry electrode material bin. Background Art

[0002] In the preparation of dry electrodes, the mixed battery materials need to be temporarily stored in a silo. The discharge port of this silo is usually designed to pour the battery materials directly between the two rollers of the calender. By precisely controlling the rotation of the rollers of the calender, the battery electrode sheets can be pressed and formed smoothly.

[0003] However, this traditional silo design exposes some problems in actual use. In particular, the discharge port of the silo is a fixed-size structure, which lacks flexibility in the amount of battery material entering between the rollers and the width of the battery sheet after pressing. This means that the width of the battery cell pole piece after pressing often exceeds the actual application requirements, especially when narrower battery cell pole pieces are required. Since the size of the discharge port cannot be adjusted, operators have to face a tricky choice: either change the discharge port of the silo to adapt to the narrower size, or perform additional trimming of the battery cell pole piece after pressing. Both methods bring additional operating steps and potential quality control issues. Although a smaller discharge port can control the width, it may affect the storage capacity of the silo, further affecting production efficiency and continuity. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art. To achieve the above purpose, an adjustable dry electrode silo is used to solve the problems raised in the above background technology.

[0005] An adjustable dry electrode silo, comprising:

[0006] Calender;

[0007] A feeding mechanism, the feeding mechanism comprising a fixed feed port assembly, an adjustment assembly and an extension feed port assembly arranged on the fixed feed port assembly, and a movable feed port assembly arranged on the extension feed port assembly;

[0008] The extended feed port assembly and the movable feed port assembly are driven by the adjusting assembly to realize the fixed feed port assembly to press the battery cell pole pieces of different widths.

[0012] As a further solution of the present invention: the extended material port assembly includes an extended material port shell arranged on the fixed material port assembly, a positioning hole arranged on the extended material port shell, and a compensation groove arranged on the extended material port shell.

[0013] As a further solution of the utility model: the movable material port assembly includes a sliding member slidably arranged on the fixed material port assembly, a connecting plate arranged on the sliding member, and a rotating plate arranged on the connecting plate.

[0014] As a further solution of the utility model: the knob includes a rotating rod arranged on the limiting hole, and a buckle arranged on the rotating rod.

[0015] As a further solution of the utility model: the variable pitch guide shaft includes a guide shaft housing arranged on the rotating rod, a first limiting groove and a second limiting groove arranged on the guide shaft housing, and a gear arranged at the end of the guide shaft housing.

[0016] As a further solution of the utility model: the sliding member includes a movable baffle shell fitted on the inclined baffle, a short inclined plate, a connecting groove and a limiting slider arranged on the movable baffle shell, and a guide block arranged on the limiting slider.

[0018] As a further solution of the utility model: the rotating plate includes a rotating plate body slidably arranged on the connecting plate, a sliding groove arranged on the rotating plate body, and a rotating plate connecting hole arranged on the rotating plate body.

[0019] Compared with the prior art, the utility model has the following technical effects:

[0020] By adopting the above technical solution, by controlling the rotation of the rotating rod, the two movable short inclined plates can be flexibly moved closer to or farther from each other, thereby accurately adjusting the size of the discharge port of the adjustable dry electrode silo. This design not only simplifies the operation, but also significantly improves the flexibility of controlling the width of the battery cell electrode sheet.

[0021] Furthermore, the setting of multiple chamfers is a clever detail. It effectively prevents the battery material from splashing when it reaches the short inclined plate position, ensuring a smooth and continuous discharge process. This design takes into account various situations that may occur in actual production, thereby improving the stability and reliability of the overall operation.

[0022] In addition, the introduction of the movable material port assembly further enhances the practicality and flexibility of the silo. It can reduce the impact of the smaller discharge port on the storage volume of the silo, which means that while adjusting the discharge port to meet different width requirements, the silo can still maintain a high storage capacity. This undoubtedly enhances the efficiency and continuity of the entire system and provides a strong guarantee for the production of high-quality dry electrodes.

[0023] In general, this innovative silo design combines a variety of optimization measures, from the adjustability of the discharge port to the multiple chamfers to prevent splashing, to the use of active discharge port components, all of which reflect a high level of attention to detail and a deep understanding of the production process. This not only improves the accuracy and efficiency of dry electrode preparation, but also provides new possibilities for technological progress and sustainable development in related industries.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Embodiment 1:

[0042] Reference Figures 1 to 3 , is the first embodiment of the utility model, which provides an adjustable dry electrode silo, including a calender 100, which includes a base 101, and a roller 102 arranged on the base 101; a feeding mechanism 200, which includes a fixed feed port assembly 201 arranged on the base 101, and an adjustment assembly 202 and an extension feed port assembly 203 are provided on the fixed feed port assembly 201, and also includes a movable feed port assembly 204 arranged on the extension feed port assembly 203;

[0043] The adjustment component 202 drives the extended material port component 203 and the movable material port component 204 to enable the fixed material port component 201 to press the battery cell pole pieces of different widths.

[0044] Specifically, the fixed feed port assembly 201 is fixedly disposed above the base 101, and the fixed feed port assembly 201 is disposed above the roller 102. In this embodiment, when the electrode is prepared by the dry method, the battery cell material is discharged from the discharge port of the fixed feed port assembly 201 and falls in the middle of the roller 102, and the calender 100 is started to press the electrode.

[0045] Furthermore, the adjustment component 202 is used to adjust the movable range of the movable material port component 204, thereby adjusting the size of the discharge port of the adjustable dry electrode material bin.

[0046] The extended material port assembly 203 is used to expand the material inlet of the adjustable dry electrode material bin, and the extended material port assembly 203 is fixedly arranged above the fixed material port assembly 201 .

[0047] During use, if it is necessary to change the size of the discharge port of the adjustable dry electrode silo, the position of the movable feed port component 204 in the fixed feed port component 201 and the extended feed port component 203 is adjusted by using the adjustment component 202, thereby changing the width of the discharge port of the adjustable dry electrode. After the position of the movable feed port component 204 is determined, the movable feed port component 204 at the current position is fixed by the adjustment component 202, so that the fixed feed port component 201, the extended feed port component 203 and the movable feed port component 204 together constitute a fixed silo entrance. At this time, the battery cell material is placed in the loading mechanism 200 and discharged to the calender 100 to perform battery cell preparation.

[0048] In summary, the embodiment of the present invention can change the width of the outlet of the adjustable dry electrode by adjusting the position of the movable feed port assembly 204 in the fixed feed port assembly 201 and the extended feed port assembly 203 by using the adjustment assembly 202, so as to control the width of the battery cell sheet when the calender 100 presses the battery cell material into a battery cell sheet.

[0049] Embodiment 2:

[0050] Reference Figures 1 to 14 , which is the second embodiment of the utility model. Different from the previous embodiment, it includes: a fixed material port assembly 201 includes a fixed material port shell 201a arranged on the base 101, and an inclined baffle 201b, a sliding groove 201c and a limiting hole 201d arranged on the fixed material port shell 201a, and also includes a limiting groove 201e arranged on the limiting hole 201d.

[0051] In detail, in the present embodiment, the fixed material port shell 201a is fixedly provided on the base 101, the inclined baffles 201b are two baffles symmetrically arranged on the fixed material port shell 201a as the material port of the material bin, and the area between the inclined baffles 201b is the material port of the dry electrode material bin, and the sliding groove 201c is a groove for limiting and sliding the movable material port assembly 204 during the sliding process. The sliding groove 201c includes two notches and is arranged in pairs on the fixed material port shell 201a, and the movable material port assembly 204 slides inside the sliding groove 201c. The limiting hole 201d is a hole for placing the knob 202a, and the knob 202a can rotate in the limiting hole 201d, and the limiting groove 201e is a groove for limiting the rotation angle of the knob 202a.

[0052] Specifically, the adjustment component 202 includes a knob 202a arranged on the fixed material mouth component 201, and a variable pitch guide shaft 202b arranged on the knob 202a, and also includes a transmission belt 202c arranged on the variable pitch guide shaft 202b. In the present embodiment, the knob 202a is rotatably arranged inside the limiting hole 201d, and the variable pitch guide shaft 202b is fixedly arranged on the knob 202a and located inside the sliding groove 201c. In the present embodiment, two variable pitch guide shafts 202b are provided, and the two variable pitch guide shafts are linked by the transmission belt 202c. When the control knob 202a is rotated, the variable pitch guide shaft 202b fixedly connected to the control knob 202a rotates synchronously with the knob 202a, and the transmission belt 202c rotates synchronously with the variable pitch guide shaft 202b fixedly connected to the control knob 202a, and transmits power to the other variable pitch guide shaft 202b, so that the two variable pitch guide shafts 202b arranged in pairs rotate synchronously.

[0053] Preferably, the extended inlet assembly 203 includes an extended inlet housing 203a disposed on the fixed inlet assembly 201, and a positioning hole 203b disposed on the extended inlet housing 203a, and also includes a compensation groove 203c disposed on the extended inlet housing 203a. In this embodiment, the extended inlet housing 203a is fixedly disposed on the fixed inlet housing 201a, and the compensation groove 203c and the inclined baffle 201b are disposed on the same side, and the rotating plate 204c is rotatably disposed on the positioning hole 203b. , let the symmetry reference plane of the two inclined baffles 201b be the symmetry plane, then the extended feed port shell 203a is closer to the reference plane than the inclined baffle 201b, that is, the extended feed port shell 203a is symmetrically arranged on both sides of the symmetry plane and the distance between the two extended feed port shells 203a is greater than the minimum distance between the two inclined baffles 201b and less than the maximum distance between the two inclined baffles 201b. The purpose is to make the battery core material fall on the inclined baffle 201b first when falling along the extended feed port shell.

[0054] In detail, the movable material port assembly 204 includes a sliding member 204a slidably arranged on the fixed material port assembly 201, and a connecting plate 204b arranged on the sliding member 204a, and also includes a rotating plate 204c arranged on the connecting plate 204b. In this embodiment, the sliding member 204a is slidably arranged between two symmetrically arranged inclined baffles 201b, and the two side surfaces of the sliding member 204a are in contact with the surfaces of the two symmetrically arranged inclined baffles 201b. The sliding member 204a is slidably arranged in the sliding grooves 201c arranged in pairs and is connected to the variable pitch guide shaft 202b.

[0055] Furthermore, the connecting plate 204b is rotatably set on the sliding member 204a, and the rotating plate 204c is slidably set on the connecting plate 204b and rotatably set on the extended material port assembly 203. When the sliding member 204a slides internally between the two inclined baffles 201b, the connecting plate 204b realizes the extension and contraction of the movable material port assembly 204 by telescoping inside the rotating plate 204c.

[0056] It should be noted that the sliding member 204a includes two identical components and both are arranged between the two inclined baffles 201b. When the two sliding members 204a slide, the distance moved relative to the symmetry center plane of the two sliding members 204a is the same, that is, the two sliding members 204a are simultaneously away from the symmetry center plane by the same distance or simultaneously close to the same distance. Similarly, the connecting plate 204b and the rotating plate 204c are two connecting plates 204b and two rotating plates 204c respectively. Since the sliding members 204a, connecting plates 204b and rotating plates 204c in this embodiment are connected in the same manner and are arranged in pairs, only one side is described in the description and no further details are given.

[0057] The rest of the structure is the same as that of Example 1.

[0058] When in use, when the discharge port of the adjustable dry electrode material bin is controlled to become smaller, that is, when the width of the pressed battery core sheet becomes shorter, the end surface of the sliding member 204a in contact with the compensation groove 203c is used as the starting point, the knob 202a is rotated, and the variable pitch guide shaft 202b rotates synchronously with the knob 202a. The paired sliding members 204a slide in the sliding groove 201c and the compensation groove 203c under the guidance of the variable pitch guide shaft 202b and move synchronously to the two sides. The symmetrical center planes of the sliding members 204a are close to the same distance. At this time, the connecting plate 204b extends out of the rotating plate 204c for a distance and serves to connect the rotating plate 204c and the sliding member 204a. One end of the rotating plate 204c is rotatably set on the positioning hole 203b and rotates accordingly with the movement of the sliding member 204a and the connecting plate 204b. At this point, the entire movable material port assembly 204 is elongated, and the discharge port of the adjustable dry electrode material bin becomes smaller.

[0059] When the discharge port of the adjustable dry electrode silo is controlled to become larger, that is, when the width of the pressed battery cell slices becomes longer, take the position of the sliding member 204a after the discharge port of the adjustable dry electrode silo is reduced as the starting point, rotate the knob 202a in the opposite direction, and the variable pitch guide shaft 202b rotates synchronously with the knob 202a. The paired sliding members 204a are synchronously moved away from the symmetrical center plane of the two sliding members 204a by the same distance under the guidance of the variable pitch guide shaft 202b. At this time, the connecting plate 204b retracts a distance from the rotating plate 204c, and the rotating plate 204c rotates accordingly with the movement of the sliding member 204a and the connecting plate 204b. At this point, the length of the entire movable material port assembly 204 is shortened, and the discharge port of the adjustable dry electrode silo becomes larger.

[0060] In summary, by controlling the knob 202a, the paired sliding members 204a can be synchronously moved toward or away from the symmetrical center plane of the two sliding members 204a by the same distance under the guidance of the variable pitch guide shaft 202b, thereby controlling the discharge port of the adjustable dry electrode silo to become smaller or larger.

[0061] Embodiment 3:

[0062] Reference Figures 1 to 14, which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a movable material port assembly of an adjustable dry electrode material bin, including a knob 202a including a rotating rod 202a-1 arranged on the limiting hole 201d, and a buckle 202a-2 arranged on the rotating rod 202a-1. In this embodiment, the rotating rod 202a-1 is rotatably arranged on the limiting hole 201d. After the buckle 202a-2 is rotated and the buckle 202a-2 is snapped into the limiting groove 201e, the rotating rod 202a-1 can no longer rotate.

[0063] Specifically, the variable pitch guide shaft 202b includes a guide shaft housing 202b-1 arranged on the rotating rod 202a-1, and a first limit groove 202b-2 and a second limit groove 202b-3 arranged on the guide shaft housing 202b-1, and also includes a gear 202b-4 arranged at the end of the guide shaft housing 202b-1. In this embodiment, the guide shaft housing 202b-1 is fixedly arranged on the rotating rod 202a-1, and the first limit groove 202b-2 and the second limit groove 202b-3 are symmetrically arranged on the guide shaft housing 202b-1, and the symmetry center plane of the first limit groove and the second limit groove is in the same plane as the symmetry center plane of the two sliding members 204a in the adjustable dry electrode silo. The gear 202b-4 is fixedly connected to the guide shaft housing 202b-1 and cooperates with the transmission belt 202c.

[0064] It should be noted that when the rotating rod 202a-1 rotates, the guide shaft housing 202b-1 will rotate synchronously with the rotating rod 202a-1, the gear 202b-4 will rotate synchronously with the guide shaft housing 202b-1 and drive the transmission belt 202c to move, and the transmission belt 202c transmits power to another gear 202b-4 symmetrically arranged on the fixed material port housing 201a, so as to realize the synchronous rotation of the two symmetrically arranged variable pitch guide shafts 202b under the action of the knob 202a.

[0065] It can be understood that, in the symmetry plane of the two inclined baffles 201b, the first limit groove 202b-2 and the second limit groove 202b-3 on one of the variable pitch guide shafts 202b are symmetrical with the first limit groove 202b-2 and the second limit groove 202b-3 on the other variable pitch guide shaft 202b relative to the symmetry plane. The purpose is to be able to use the rotating rod 202a-1 to control the rotation of the two variable pitch guide shafts 202b, so that the paired sliding members 204a can synchronously move away from or approach the symmetry center plane of the two sliding members 204a by the same distance under the guiding action of the variable pitch guide shafts 202b.

[0066] In detail, the sliding member 204a includes a moving baffle housing 204a-1 that is fitted on the inclined baffle 201b, and a short inclined plate 204a-2, a connecting groove 204a-3 and a limiting slider 204a-4 that are arranged on the moving baffle housing 204a-1, and also includes a guide block 204a-5 that is arranged on the limiting slider 204a-4. In this embodiment, the two side surfaces of the moving baffle housing 204a-1 are respectively fitted with the surfaces of the two symmetrically arranged inclined baffles 201b. The corresponding short inclined plates 204a-2 of the two sliding members 204a are arranged face to face, that is, the two short inclined plates 204a-2 are oriented in a direction that they can contact each other, and the limit slider 204a-4 is slidably arranged in the sliding groove 201c. The sliding member 204a in this embodiment includes two limit sliders 204a-4, and the two limit sliders 204a-4 are respectively arranged in two symmetrical sliding grooves 201c, and the guide block 204a-5 is arranged on the variable pitch guide shaft 202b.

[0067] It should be noted that the positions of the two sliding members 204a used in pairs on the same variable pitch guide shaft 202b are as follows: the guide block 204a-5 of one sliding member 204a is set on the first limiting groove 202b-2, and the guide block 204a-5 of the other sliding member 204a is set on the second limiting groove 202b-3.

[0068] Furthermore, the connecting plate 204b includes a connecting shaft 204b-1 rotatably set on the connecting groove 204a-3, and a connecting plate body 204b-2 set on the connecting shaft 204b-1, and also includes an inclined chamfer 204b-3 set on the connecting plate body 204b-2. In this embodiment, the connecting plate body 204b-2 is fixedly set on the connecting shaft 204b-1, and the inclined chamfer 204b-3 is set on the surface of the connecting plate body 204b-2 close to the short inclined plate 204a-2. Its purpose is to prevent the battery cell material from falling on the connecting plate body 204b-2 and splashing out when it is about to reach the position of the short inclined plate 204a-2.

[0069] Specifically, the rotating plate 204c includes a rotating plate body 204c-1 slidably set on the connecting plate 204b, and a sliding groove 204c-2 set on the rotating plate body 204c-1, and also includes a rotating plate connecting hole 204c-3 set on the rotating plate body 204c-1. In the present embodiment, the rotating plate connecting hole 204c-3 is rotatably set on the positioning hole 203b, and the connecting plate body 204b-2 is slidably set in the sliding groove 204c-2 and can be extended and retracted in the sliding groove 204c-2. The surface of the rotating plate body 204c-1 is also provided with a chamfer, and its setting purpose is the same as that of the inclined chamfer 204b-3, which will not be repeated here.

[0070] The rest of the structure is the same as that of Example 2.

[0071] During use, when the discharge port of the adjustable dry electrode silo is controlled to become smaller, the end surface of the sliding member 204a in contact with the compensation groove 203c is used as the starting point to control the rotation of the rotating rod 202a-1, and the guide shaft housing 202b-1 rotates synchronously with the rotating rod 202a-1. The guide block 204a-5 on one side of the two symmetrically arranged sliding members 204a is set in the first limiting groove 202b-2, and the guide block 204a-5 on the same side of the other sliding member is set in the second limiting groove 202b-3. When the guide shaft housing 202b-1 rotates, The two guide blocks 204a-5 slide inside the first limit groove 202b-2 and the second limit groove 202b-3 respectively, and the gear 202b-4 rotates synchronously with the rotation of the guide shaft housing 202b-1, and makes the transmission belt 202c move synchronously with the guide shaft housing 202c-1, so that the other variable-pitch guide shaft housing 202b-1 used in pair rotates synchronously. In this process, the purpose is to make the two movable short inclined plates 204a-2 move in a direction close to each other so as to reduce the size of the discharge port of the adjustable dry electrode silo.

[0072] Furthermore, for the sake of convenience, only the movement state of the movable baffle shell 204a-1 on one side and the movement state of the corresponding part of the movable material port assembly 204 connected thereto are described here, and the movement effect of the movement state of the movable baffle shell 204a-1 on the other side and the movement state of the corresponding part of the movable material port assembly 204 connected thereto are the same. When the two movable baffle shells 204a-1 move toward each other, the connecting shaft 204b-1 rotates in the connecting groove 204a-3 and moves with the movement of the connecting groove 204a-3, the connecting plate body 204c-1 slides in the sliding groove 204c-2 and extends out of a part of the sliding groove 204c-2, and the rotating plate body 204c-1 and the connecting The plate body 204b-1 fits well, so when the connecting plate body 204b-1 moves, it drives the rotating plate body 204c-1 to rotate with the rotating plate connecting hole 204c-3 as the center. At this time, the length of the entire movable material port assembly 204 becomes longer. When the two movable short inclined plates 204a-2 reach the required position according to needs, the rotating buckle 202a-2 is rotated and the buckle 202a-2 is snapped into the limiting groove 201e to fix the rotating rod 202a-1, so that the material bin composed of the movable material port assembly 204, the extended material port assembly 203 and the fixed material port assembly 201 is fixed. In this process, the influence of the discharge port of the adjustable dry electrode material bin on the material storage volume of the bin is reduced when the discharge port becomes smaller.

[0073] It should be noted that the operation method when controlling the discharge port of the adjustable dry electrode silo to become larger is similar to the operation method when controlling the discharge port of the adjustable dry electrode silo to become smaller, both of which are achieved by controlling the rotation of the rotating rod 202a-1, and can be easily observed through the attached drawings of the embodiments of the present invention, so it will not be repeated here.

[0074] In summary, the embodiment of the present invention can realize the movement of the two movable short inclined plates 204a-2 towards or away from each other by controlling the rotation of the rotating rod 202a-1, so as to reduce or increase the size of the discharge port of the adjustable dry electrode silo, thereby controlling the width of the pressed battery cell sheets. The setting of multiple chamfers can prevent the battery cell materials from falling on the connecting plate body 204b-2 and splashing out when they are about to reach the position of the short inclined plate 204a-2. At the same time, the setting of the movable material port assembly 204 also reduces the influence of the discharge port of the adjustable dry electrode silo on the storage volume of the silo when it becomes smaller.
