Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, specifically a calender feeding device. Background Technology

[0002] A calender consists of two or more rollers arranged according to the heating method. It can be divided into cold pressing and hot pressing. Cold pressing is suitable for materials that do not require heating, such as graphite films, graphite sheets, microwave absorbing materials, shielding materials, magnetic materials, and non-ferrous metals. Hot pressing is further divided into water heating, electric heating, oil heating, and electromagnetic heating. Both types of machines press and stretch materials such as rubber, silicone rubber, silicone rubber, phase change materials, PTFE, or plastics into sheets of a certain thickness and surface shape at a specific temperature. They can also be used to coat fiberglass or steel wire fabrics with adhesive.

[0003] In existing dry electrode preparation processes, fibrous electrode materials need to be crushed into powder of a certain particle size and fed evenly onto the work rolls of a calender. The powder feeding and conveying is generally done manually with the aid of a vibrator to deliver the material to the calender. Simple vibration feeding often results in inconsistent powder flow thickness at the outlet or powder agglomeration, which can adversely affect the film-forming effect of the calender.

[0004] In view of this, there is an urgent need for a calender feeding device to solve the above problems. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0010] The material distribution layer consists of several layers extending from one end of the homogenizing pipe inlet to one end of the homogenizing pipe outlet, with the material distribution plates of adjacent material distribution layers being staggered.

[0011] The cross-section of the material distribution plate in the third side direction is V-shaped or arc-shaped, and one end of the opening of the material distribution plate faces the outlet of the homogenizing pipe.

[0012] The top of the vibratory feeder is provided with a material trough and several material channels. The material trough is located directly below the outlet of the homogenizing pipe, and the several material channels extend from the material trough to the side away from the homogenizing pipe.

[0013] The material channel is in a straight line, and several material channels are arranged in parallel.

[0014] The material channel extends in a tree-like topology from the material trough toward the side away from the homogeneous pipe.

[0015] A material distribution plate is provided on the top of the vibratory feeder, and the material distribution plate is located on the side of the material channel away from the material trough.

[0016] A secondary frame is provided on one side of the main frame, and a discharge bin is provided on the secondary frame. The inlet of the discharge bin is located at one end of the discharge port of the vibrating plate. The inlet of the discharge bin, the discharge port of the discharge bin, and the discharge port of the vibrating plate are all in a straight line, and the extension directions of the inlet of the discharge bin, the discharge port of the discharge bin, and the discharge port of the vibrating plate are all the same.

[0017] A stirring shaft is provided inside the discharge hopper, and a second driving component is provided on one side of the discharge hopper. The second driving component is used to drive the stirring shaft to rotate, and the axial direction of the stirring shaft is consistent with the extension direction of the discharge port of the discharge hopper.

[0018] The auxiliary frame is equipped with a metering wheel and a first driving component. The metering wheel is located at the discharge port of the discharge bin. The metering wheel is circumferentially provided with a plurality of metering grooves. The metering grooves are in a straight line shape. The extension direction of the metering grooves is consistent with the extension direction of the discharge port of the discharge bin. The first driving component is used to drive the metering wheel to rotate.

[0019] A scraper is provided on the sub-frame, and the scraper is located on one circumferential side of the metering wheel, with one end of the scraper abutting against the circumferential side of the metering wheel.

[0020] A baffle is provided on the sub-frame, and the baffle is located directly below the scraper. The baffle is inclined from the side away from the direct below the metering wheel to the side away from the direct below the metering wheel, and the inclination direction is downward.

[0027] The above-described structure of this utility model can achieve the following beneficial effects:

[0028] In operation, the material is placed in the feeding hopper, and then enters the granulation mechanism through the discharge port of the feeding hopper. The material is then broken down into uniformly sized powder by the granulation mechanism, and then enters the homogenizing pipe. Because the homogenizing pipe is equipped with several distribution plates, the accumulated material is evenly broken down after entering the homogenizing pipe. The broken material then falls onto the vibrating plate at the discharge port of the homogenizing pipe. Driven by the vibrator, the vibrating plate vibrates, uniformly conveying the uniformly sized powder to the next process equipment. Through the action of the granulation mechanism, the material is broken down into uniformly sized powder, and then uniformly conveyed by the vibration of the vibrating plate, thus ensuring a consistent powder flow thickness at the discharge port. This solves the problem of uneven feeding in the calender and improves the film-forming effect of the calender. Attached Figure Description

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0040] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0041] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0042] like Figures 1-3 As shown, a calender feeding device includes: a main frame, on which a feeding hopper 1, a homogenizing pipe 2, a vibrating plate 3 and a vibrator 4 are arranged. The feeding port of the homogenizing pipe 2 is connected to the discharging port of the feeding hopper 1, and the discharging port of the homogenizing pipe 2 is located directly above the vibrating plate 3. The vibrator 4 drives the vibrating plate 3 to vibrate.

[0043] A material distribution layer is provided inside the homogenizing pipe 2. The material distribution layer includes several material distribution plates 5, which are arranged sequentially from the first circumferential side of the homogenizing pipe 2 to the second circumferential side of the homogenizing pipe 2. The two ends of the material distribution plates 5 extend to the third circumferential side and the fourth circumferential side of the homogenizing pipe 2, respectively. The first and second sides are arranged opposite to each other, and the third and fourth sides are arranged opposite to each other. In addition to the above structure, the material distribution layer can also be composed of a grid-like plate to disperse the material.

[0044] like Figures 2-4 As shown, in order to further improve the uniformity of material dispersion, several layers of material distribution layers are provided from one end of the inlet of the homogenizing pipe 2 to one end of the outlet of the homogenizing pipe 2. The material distribution plates 5 of two adjacent material distribution layers are staggered. By setting multiple layers of material distribution plates 5, the material is dispersed multiple times, which improves the material dispersion effect. In addition, the specific shape of the material distribution plate 5 is rationally designed according to the production and processing requirements. In this embodiment, the cross-section of the material distribution plate 5 in the third side direction is preferably V-shaped or arc-shaped. One end of the opening of the material distribution plate 5 faces the outlet of the homogenizing pipe 2 (in this embodiment, the homogenizing pipe 2 is preferably set vertically, that is, one end of the opening of the material distribution plate 5 faces downward). In this way, the material will not be left on the material distribution plate 5, and after the material falls on the material distribution plate 5, it slides off from both sides of the material distribution plate 5, which effectively improves the uniformity of material dispersion.

[0045] like Figure 5 and Figure 6 As shown, the top of the vibratory feeder 3 is provided with a trough 31 and several material channels 32. The trough 31 is located directly below the outlet of the homogenizing pipe 2. The material channels 32 extend from the trough 31 to the side away from the homogenizing pipe 2. After the material is dispersed by the homogenizing pipe 2, it falls evenly into the trough 31. Driven by the vibrator 4, the vibratory feeder 3 vibrates, causing the material to move evenly towards the material channels 32, and then be conveyed to the outlet of the vibratory feeder 3 through the material channels 32. The specific shape of the material channels 32 can be rationally designed according to the actual production and usage requirements. For example, the material channels 32 can be in a straight line and the material channels 32 can be arranged in parallel. In this embodiment, the specific structure of the material channels 32 can also be: the material channels 32 extend from the trough 31 to the outlet of the vibratory feeder 3. 31 extends in a tree-like topology away from the homogenizing pipe 2. That is, the material channel 32 is arranged in a first stage, second stage, third stage and so on from the material trough away from the homogenizing pipe 2. Each first stage material channel has at least two second stage material channels at its tail, and each second stage material channel has at least two third stage material channels at its tail, so as to evenly convey the material to the discharge port of the vibrating plate 3. Furthermore, a material equalization plate 33 is provided on the top of the vibrating plate 3. The material equalization plate 33 is located on the side of the material channel 32 away from the material trough 31. When the material is conveyed to the material equalization plate 33, the material is vibrated and passes over the material equalization plate 33, and is spread more evenly at the tail of the vibrating plate 3, thus resulting in a uniform output.

[0046] like Figure 1 , Figure 7 as well as Figure 8 As shown, a secondary frame is provided on one side of the main frame, and a discharge bin 8 is provided on the secondary frame. The inlet of the discharge bin 8 is located at one end of the discharge port of the vibrating plate 3. The inlet, outlet, and discharge port of the discharge bin 8 and the discharge port of the vibrating plate 3 are all in a straight line. The extension directions of the inlet, outlet, and discharge port of the discharge bin 8 and the discharge port of the vibrating plate 3 are all the same. A stirring shaft 81 is provided inside the discharge bin 8. A second driving member is provided on one side of the discharge bin 8. The second driving member is used to drive the stirring shaft 81 to rotate. The axial direction of the stirring shaft 81 is consistent with the extension direction of the discharge port of the discharge bin 8. In this way, by driving the stirring shaft 81 to rotate through the second driving member, the material in the discharge bin 8 is prevented from agglomerating, and the material is distributed as evenly as possible in the discharge bin 8. Small nozzles can also be provided on the stirring shaft 81 and the bin wall of the discharge bin 8 to break up arches and prevent the material from sticking to the wall.

[0047] like Figure 7 and Figure 8 As shown, to ensure uniform and quantitative material delivery to the next process stage, a metering wheel 6 and a first driving component are installed on the auxiliary frame. The metering wheel 6 is located at the discharge port of the discharge hopper 8. Several metering grooves 61 are evenly arranged circumferentially around the metering wheel 6. The metering grooves 61 are in a straight line, and their extension direction is consistent with the extension direction of the discharge port of the discharge hopper 8. The first driving component drives the metering wheel 6 to rotate. Thus, by driving the metering wheel 6 to rotate, a seal is formed between the circumference of the metering wheel 6 and the circumference of the discharge port of the discharge hopper 8. In other words, during the rotation of the metering wheel 6, material will not leak from the circumference of the discharge port of the discharge hopper 8 into the metering wheel 6. Material can only enter the metering tank 61 and leak to the outside. When the metering tank 61 moves to the discharge port of the discharge bin 8, the material falls into the metering tank 61. When the feeding tank 61 moves downward, the material falls from the metering tank 61 to the next process equipment. The advantage of this design is that since the capacity of the metering tank 61 is fixed, the rotation speed of the metering wheel 6 can be controlled by the first driving component, thereby controlling the output efficiency of the material. In actual use, material level sensors can be installed in the discharge bin 8 and at the discharge port of the discharge bin 8 to detect the material position and achieve real-time control of the material level, avoiding the agglomeration of material due to long-term exposure to high temperature.

[0048] Further optimizations include, for example Figure 8As shown, a scraper 7 is installed on the auxiliary frame. The scraper 7 is located on one circumferential side of the metering wheel 6, with one end of the scraper 7 abutting against the circumferential side of the metering wheel 6. The side of the scraper 7 near the metering wheel 6 can be made of a soft material. When the metering groove 61 on the metering wheel 6 moves upward, one side of the scraper 7 sweeps across the metering groove 61 to clean the material remaining in the metering groove 61. The scraped material falls to the next process equipment, ensuring the accuracy of material metering. In addition, a baffle 14 is installed on the auxiliary frame. The baffle 14 is located directly below the scraper 7. The baffle 14 is inclined from the side away from the direct below the metering wheel 6 to the side away from the direct below the metering wheel 6, with the inclination direction facing downward. This guides the material scraped by the scraper 7, so that the scraped material and the material falling naturally in the metering groove 61 fall into the same position, preventing the scraped material from remaining in other parts of the equipment.

[0049] like Figure 1 As shown, in order to monitor the amount of material in the feeding hopper 1, the main frame includes an upper frame 15 and a lower frame 16 located at the bottom of the upper frame 15. The feeding hopper 1 is located on the upper frame 15, and the homogenizing pipe 2, vibrating plate 3, and vibrator 4 are located on the lower frame 16. A weighing sensor 9 is installed between the upper frame 15 and the lower frame 16. Thus, when material falls from the feeding hopper 1 or material is added to the feeding hopper 1, the overall weight of the upper frame 15 will change. The weight change is monitored by the weighing sensor 9. When there is a problem with the feeding or unloading of material in the feeding hopper 1, the value measured by the weighing sensor 9 can be used to obtain the information.

[0050] Further optimizations include, for example Figure 9 As shown, a drive shaft 10 is provided inside the feeding hopper 1. The drive shaft 10 is arranged from top to bottom inside the feeding hopper 1. Several blades 11 are arranged circumferentially on the drive shaft 10. A second drive component is provided on the feeding hopper 1. The second drive component is used to drive the drive shaft 10 to rotate. In this way, the material in the feeding hopper 1 is agitated by driving the drive shaft 10 to rotate, so as to avoid the material in the feeding hopper 1 from clumping or blocking the feeding hopper 1.

[0051] like Figure 1 and Figure 9 As shown, the discharge port of the feeding hopper 1 is equipped with a granulation mechanism 12. The inlet of the homogenizing pipe 2 is connected to the outlet of the granulation mechanism 12. By setting the granulation mechanism 12, the fibrous clumps of material are broken into powder with uniform particle size, which facilitates the material transportation and meets the requirements of the next step of calendering.

[0052] like Figure 1As shown, in this embodiment, the discharge port of the feeding hopper 1 is located at the bottom of the feeding hopper 1, and the top of the feeding hopper 1 is provided with a feeding pipe 13. The homogenizing pipe 2 is set vertically, and the vibrating plate 3 is set horizontally or gradually tilts downward on the side of the vibrating plate 3 near the discharge hopper 8. The feeding port and discharge port of the discharge hopper 8 are respectively set at the top and bottom of the discharge hopper 8. The material is input into the feeding hopper 1 through the feeding pipe 13. The vertically set homogenizing pipe 2 can better distribute the powder from the granulation mechanism 12 evenly and evenly fall onto the vibrating plate 3.

[0053] In summary, during use, the material is placed in the feeding hopper 1, and then enters the granulation mechanism 12 through the discharge port of the feeding hopper 1. After being dispersed into uniformly sized powder by the granulation mechanism 12, the material then enters the homogenizing pipe 2. Since several distribution plates 5 are set in the homogenizing pipe 2, the accumulated material is evenly dispersed after entering the homogenizing pipe 2. The dispersed material then falls onto the vibrating plate 3 at the discharge port of the homogenizing pipe 2. Driven by the vibrator 4, the vibrating plate 3 vibrates, evenly conveying the dispersed material to one end of the discharge port of the vibrating plate 3, and finally falling into the discharge hopper 8. After the rotation of the metering wheel 6, the material is fed to the next process equipment in a timed and quantitative manner. Through the internal structural design of the homogenizing pipe 2, the material is evenly conveyed to the vibrating plate 3, and then evenly conveyed by the vibration of the vibrating plate 3, thereby ensuring that the thickness of the powder flow at the discharge port is consistent, solving the problem of uneven feeding in the calender, and improving the film-forming effect of the calender.

[0054] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
