Description

Technical Field

[0001] This utility model relates to the technical field of powder feeding equipment, and in particular to a powder feeding station. Background Technology

[0002] In the production of chemical materials, factories typically package powder raw materials in bags for convenient storage and transportation; these bags are commonly known as powder bags. When production begins, workers can then move the powder bags to the feeding station for use.

[0003] Utility model patent CN219155948U discloses a dust-proof feeding device. This device effectively reduces the amount of dust flowing towards workers by separating the feeding area and the inlet, thus improving the work environment. Furthermore, by incorporating a dust-collecting area and a dust-collecting channel, it absorbs dust between the feeding area and the inlet, effectively reducing the dust content at the inlet and thus minimizing dust overflow. This significantly reduces the amount of dust in the workshop and improves its safety.

[0004] However, in the actual feeding process, since there are many powder bags that need to be opened, there are also many waste bags after feeding. Since the dustproof feeding device mentioned above does not have a structure to collect waste bags, the waste bags after feeding can only be temporarily piled up in the small feeding hopper. This will occupy the feeding operation space, interfere with the powder bag feeding and the operation of shaking the waste bags, and can only be taken out all at once after feeding is completed, which affects production efficiency. Utility Model Content

[0005] In order to overcome the defects of the existing technology, this utility model provides a powder feeding station.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a powder feeding station includes a feeding hopper with an internal operating space. The side wall of the feeding hopper is provided with an inlet communicating with the operating space and gloves for manual operation in the operating space. The bottom of the feeding hopper is provided with a hopper communicating with the operating space. Multiple conveying rollers are provided in the operating space at intervals. The multiple conveying rollers are located above the opening of the hopper. The station also includes a collection hopper. The collection hopper is located at the bottom of the feeding hopper and on one side of the hopper. The collection hopper is connected to the operating space through an inlet, and an outlet is opened on the side wall of the collection hopper. The multiple conveying rollers are located between the inlet and the inlet.

[0007] As a further embodiment, the powder feeding station also includes a bag feeder and a first driving mechanism. The first driving mechanism is installed on the side wall of the collection bin, and the bag feeder is located inside the collection bin. One end of the bag feeder is connected to the first driving mechanism for transmission. The first driving mechanism can drive the bag feeder to send the waste bag out from the outlet.

[0008] As a further embodiment, the bag feeder is in the shape of a double helix, the first driving mechanism is a first servo motor, one end of the helical bag feeder is connected to the first servo motor for transmission, and the other end of the helical bag feeder extends to the outlet.

[0009] As a further embodiment, the inlet is located on the left side of the glove, and the opening is located on the right side of the glove.

[0010] As a further embodiment, the powder feeding station also includes a conveying device for conveying powder bags, with one end of the conveying device located at the inlet.

[0011] As a further embodiment, the powder feeding station also includes a second drive mechanism and a door. Both the second drive mechanism and the door are installed on the side wall of the feeding hopper. The second drive mechanism can drive the door to close or open the inlet.

[0012] As a further embodiment, the top of the door is movably connected to the side wall of the feeding bin via a hinge, and the second driving mechanism is a cylinder, the output end of which is hinged to the connecting plate in the middle of the door so that the door can close or open the inlet.

[0013] As a further embodiment, the powder feeding station also includes a powder scraper and a second servo motor that drives the powder scraper to rotate. The second servo motor is installed next to the discharge port at the bottom of the hopper. The powder scraper is placed inside the hopper, and one end of the powder scraper is connected to the second servo motor for transmission.

[0014] As a further embodiment, the powder feeding station also includes an exhaust fan and a filter, both of which are located at the top of the feeding hopper. The air inlet of the filter is connected to the operating space, and the air outlet of the filter is connected to the air inlet of the exhaust fan.

[0015] The beneficial effects of this invention are as follows: Powder bags enter the operating space of the feeding hopper from the inlet and move slowly via conveyor rollers, eventually settling on multiple conveyor rollers. The operator can insert their hands into gloves to cut the powder bags with a knife, allowing the powder inside to fall into the hopper through the gaps between the spaced conveyor rollers. The operator can also shake the waste bags within the operating space to expel as much powder as possible. The enclosed space of the feeding hopper prevents dust from flying out when the operator shakes the waste bags, effectively reducing dust levels in the workshop and improving safety. Simultaneously, since the multiple conveyor rollers are located between the inlet and the feed hopper, it is convenient for the operator to drop the waste bags into the collection hopper through the feed hopper. The waste bags are collected in the collection hopper without occupying operating space or interfering with the feeding operation. They can be removed from the collection hopper's outlet after feeding is complete, thus improving production efficiency. Attached Figure Description

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] As attached Figure 1-4 As shown, this utility model provides a powder feeding station, including a feeding bin 1 with an internal operating space 11. The side wall of the feeding bin 1 is provided with an inlet 12 communicating with the operating space 11 and gloves 13 for manual operation within the operating space 11. The bottom of the feeding bin 1 is provided with a hopper 2 communicating with the operating space 11. Multiple spaced conveyor rollers 3 are provided within the operating space 11, positioned above the opening of the hopper 2. These conveyor rollers 3 support the powder bags, eliminating the need for operators to lift the powder bags forcefully, thus simplifying operation. The powder feeding station also includes a collection bin 4, located at the bottom of the feeding bin 1 and on one side of the hopper 2. The collection bin 4 communicates with the operating space 11 through an inlet 14 at the bottom of the feeding bin 1, and an outlet 41 is provided on its side wall. Multiple conveyor rollers 3 are located between the inlet 12 and the inlet 14.

[0025] It should be noted that, as shown in the attached document... Figure 1 As shown, the feeding bin 1 can be supported by support legs, thus standing upright on the ground.

[0026] Specifically, as shown in the attached document Figure 4 As shown, powder bags enter the operating space 11 of the feeding hopper 1 through inlet 12 and move slowly via conveyor rollers 3, eventually stopping on multiple conveyor rollers 3. The operator can insert their hands into gloves 13 to cut the powder bags with a knife, allowing the powder inside to fall into the hopper 2 through the gaps between the multiple spaced conveyor rollers 3. The operator can also shake the waste bags within the operating space 11 to expel as much powder as possible. The enclosed space formed by the feeding hopper 1 prevents dust from flying out when the operator shakes the waste bags, effectively reducing the amount of dust in the workshop and improving the safety factor.

[0027] Meanwhile, since multiple conveyor rollers 3 are located between the inlet 12 and the entrance 14, it is convenient for the feeding personnel to drop the waste bags into the collection bin 4 through the entrance 14. The waste bags are collected in the collection bin 4, without occupying the operating space 11 or interfering with the feeding operation. The waste bags can be removed from the outlet 41 of the collection bin 4 after feeding is completed, thereby improving production efficiency. In a preferred embodiment, the inlet 12 is located on the left side of the glove 13, and the entrance 14 is located on the right side of the glove 13. This conforms to the operating habits of the feeding personnel and can improve production efficiency.

[0028] As a further extension of the plan, see attached Figure 3 As shown, the powder feeding station also includes a bag feeder 5 and a first drive mechanism 51. The first drive mechanism 51 is installed on the side wall of the collection bin 4, and the bag feeder 5 is located inside the collection bin 4. One end of the bag feeder 5 is connected to the first drive mechanism 51 for transmission. The first drive mechanism 51 can drive the bag feeder 5 to send the waste bag out from the outlet 41, thereby replacing the manual operation of taking the waste bag out from the outlet 41, and further improving the automation and production efficiency of the equipment.

[0029] The above solution has the following two specific implementations:

[0030] Example 1: In this preferred embodiment, the bag feeder 5 is in a double helix shape. The first drive mechanism 51 is a first servo motor. One end of the helical bag feeder 5 is connected to the first servo motor, and the other end of the helical bag feeder 5 extends to the outlet 41. The first servo motor drives the helical bag feeder 5 to rotate, causing the waste bag to be fed out from the outlet 41.

[0031] Example 2: The bag feeder 5 is in the shape of a circular plate. The first driving mechanism 51 is a cylinder. The circular plate-shaped bag feeder 5 is installed at one end of the output shaft of the cylinder. The circular plate-shaped bag feeder 5 is driven by the cylinder to push the waste bag and push it out from the outlet 41.

[0032] Furthermore, as shown in the appendix Figure 4 As shown, the powder feeding station also includes a conveying device 6 for conveying powder bags, with one end of the conveying device 6 located at the inlet 12. The conveying device 6 can be a conveyor belt, which transports the powder bags to the inlet 12. The subsequent powder bag pushes the previous powder bag into the operating space 11 of the feeding hopper 1 and stops on multiple spaced conveyor rollers 3.

[0033] As attached Figure 4-6 As shown, the powder feeding station also includes a second drive mechanism 7 and a door 71. Both the second drive mechanism 7 and the door 71 are installed on the side wall of the feeding hopper 1. The second drive mechanism 7 can drive the door 71 to close or open the inlet 12. (See attached diagram) Figure 6 As shown, the second drive mechanism 7 can drive the door 71 to open, allowing the powder bag to enter the operating space 11 of the feeding hopper 1 through the inlet 12; as shown in the attached diagram. Figure 5 As shown, after the powder bag enters, the second drive mechanism 7 drives the door 71 to close the inlet 12 to prevent dust from flying out of the inlet 12 when the waste bag is shaken.

[0034] The above solution has the following two specific implementations:

[0035] Example 1: In the preferred embodiment, the top of the door 71 is movably connected to the side wall of the feeding bin 1 via a door hinge 72. The second drive mechanism 7 is a cylinder. The output end of the cylinder is hinged to the connecting plate 73 in the middle of the door 71. The cylinder pushes the door 71 to flip, closing or opening the inlet 12.

[0036] Example 2: The door 71 is movably mounted on the side wall of the feeding bin 1 via a guide rail and is located above the inlet 12. The second drive mechanism 7 is a servo motor. The servo motor drives the door 71 via a lead screw and a lead screw seat fixed to the door 71, so that the door 71 moves up and down along the guide rail to close or open the inlet 12.

[0037] Of course, in some embodiments, as shown in the appendix Figure 3 As shown, the powder feeding station also includes a powder scraper 8 and a second servo motor 81 that drives the powder scraper 8 to rotate. The second servo motor 81 is installed next to the discharge port 21 at the bottom of the hopper 2. The powder scraper 8 is placed inside the hopper 2, and one end of the powder scraper 8 is connected to the second servo motor 81 for transmission. After the feeding personnel feed the powder, the powder falls into the hopper 2. The second servo motor 81 drives the powder scraper 8 to rotate, thereby agitating the powder and causing it to flow out from the discharge port 21 at the bottom of the hopper 2, preventing the powder from accumulating in the hopper 2.

[0038] Of course, dust will inevitably be generated during this feeding process. (See attached image) Figure 4As shown, the powder feeding station also includes an exhaust fan 9 and a filter 91. Both the exhaust fan 9 and the filter 91 are located at the top of the feeding hopper 1. The air inlet of the filter 91 is connected to the operating space 11, and the air outlet of the filter 91 is connected to the air inlet of the exhaust fan 9. The exhaust fan 9 draws the air filtered by the filter 91 out of the feeding hopper 1, maintaining a negative pressure inside the feeding hopper 1 to prevent dust from flying out from the outlet 41 of the collection hopper 4.

[0039] It should be noted that the powder feeding station of this utility model can be installed on the second floor. After feeding, the powder in the hopper 2 flows through the discharge port 21 and the pipeline to the mixer installed on the first floor for mixing.

[0040] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
