Description

Technical Field

[0001] This utility model relates to the technical field of granular material feeding equipment, and specifically to a granular material feeding equipment. Background Technology

[0002] In pet pee pads, polymer materials are added to the cotton fibers to improve the pad's performance. The addition of these polymer materials requires a polymer feeding device. This device typically includes a storage tank with a material inlet and an outlet, the outlet of which connects to a cotton fiber conveying box. Specifically, in the production line, the storage tank contains the polymer material, which falls through the outlet into the cotton fiber conveying box and mixes with the cotton fibers already there.

[0003] Chinese patent CN213107686U discloses a feeding device for polymer material production. This feeding device uses a spring, a telescopic tube, and an inclined slide plate to continuously feed materials through a discharge pipe. However, this device still has the following problems:

[0004] 1. The storage tank is usually located higher than the cotton wadding conveyor. When it is necessary to add polymer material, staff usually need to use ladders to add the polymer material into the storage tank. It is also inconvenient for staff to observe the remaining amount of material in the storage tank, which is not very convenient.

[0005] 2. When adding polymer materials to cotton wadding, it is necessary to accurately control the amount of polymer materials added and ensure that the flow rate of polymer materials is uniform during transportation. Utility Model Content

[0028] Example 1

[0029] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A pellet material feeding device includes a main storage tank 1 and a frame 2. The main storage tank 1 is placed on the ground to the left of the frame 2. The top of the frame 2 is provided with a primary storage tank 31 and a secondary storage tank 32 for material transfer. The primary storage tank 31 is connected to the main storage tank 1 through a conveying pipe 11. A conveying pump is provided on the conveying pipe 11. The primary storage tank 31 and the secondary storage tank 32 are internally interconnected and are arranged sequentially from top to bottom along the height direction. The bottom of the primary storage tank 31 and the secondary storage tank 32 are provided with a detection structure 7 for detecting the volume and mass of the material.

[0030] The bottom of the secondary storage tank 32 is fixedly equipped with a secondary discharge port 33. The bottom end of the secondary discharge port 33 passes through the frame 2 and extends to the bottom of the inner top of the frame 2. A feeding assembly is provided on the upper left side of the frame 2. An installation plate is fixedly connected to the upper rear side of the frame 2. A conveyor belt 5 is installed on the installation plate. The inlet end of the conveyor belt 5 is located below the secondary discharge port 33. The outlet end of the conveyor belt 5 is aligned with the inlet of the feeding assembly. A width adjustment mechanism 4 for controlling the width of the secondary discharge port 33 is provided on the upper right side of the frame 2.

[0031] Specifically, the pellet material spreading and feeding equipment is used in the pet pee pad production line, and the discharge port of the feeding component is connected to the cotton wadding conveying device; the conveying device is usually a box-shaped structure, and a fan is installed inside the box-shaped structure to blow up the cotton wadding; the polymer material enters the conveying device through the discharge port and mixes with the cotton wadding floating in the box, and the cotton wadding mixed with polymer material is shaped into a cotton strip structure in the downstream production line.

[0032] Through the technical solution of this utility model, the polymer material in the main storage tank 1 located on the ground is transported to the primary storage tank 31 located at a higher position via the cooperation of the conveying pipe 11 and the conveying pump, facilitating the addition of polymer material to the primary storage tank 31. Furthermore, the sequentially connected primary storage tank 31 and secondary storage tank 32, along with the detection structures 7 installed at the bottom of the primary storage tank 31 and the secondary storage tank 32, allow personnel to easily monitor the material status in the primary storage tank 31 and the secondary storage tank 32 in real time, facilitating the timely addition of polymer material to the main storage tank 1.

[0033] In use, this utility model uses the detection structure 7 set in the primary storage tank 31 and the secondary storage tank 32 to detect the volume and quality of the material, thereby controlling the input amount of the material and maintaining accurate material transportation. The material falls into the feed end of the conveyor belt 5 through the secondary discharge port 33, and under the action of the width adjustment mechanism 4, the granular material is spread evenly on the conveyor belt 5 when it falls, so that the material is evenly distributed. At the same time, it is easy to adjust the width of the secondary discharge port 33, ensuring the amount of polymer material mixed with cotton wool.

[0034] The detection structure 7 is configured as a 3D radar level scanner, and multiple 3D radar level scanners are provided and fixedly installed on the inner walls of the primary storage tank 31 and the secondary storage tank 32 respectively.

[0035] The 3D radar level scanner is an existing technology. The ULM-3D-5 model of 3D radar level scanner can accurately measure the level, volume and mass of materials stored in warehouses and open-air warehouses.

[0036] The bottom of the primary storage tank 31 is equipped with a flow regulating valve for controlling the material flow at the inlet of the secondary storage tank 32.

[0037] The bottom of the secondary discharge port 33 is set as a square opening.

[0038] The square opening facilitates the formation of a rectangular flat material at the feed point of conveyor belt 5;

[0039] The feeding assembly includes a feeding box 61 and a feeding pipe 6. The feeding box 61 is fixedly installed on the upper left side of the frame 2. The inlet end of the feeding pipe 6 is fixedly connected to the bottom of the feeding box 61. The outlet end of the conveyor belt 5 is located at the inlet of the feeding box 61. The outlet end of the feeding pipe 6 is used to connect to the cotton wadding conveying device in the pet pee pad so that the polymer material is mixed with the cotton wadding.

[0040] Example 2

[0041] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-3The width adjustment mechanism 4 includes bolts and a rotatable square plate. An opening is provided on the left outer wall of the secondary discharge port 33. One end of the square plate is rotatably connected to the top of the opening. One end of the square plate is fixed to the secondary discharge port 33 by bolts. The secondary discharge port 33 and the outer wall of the square plate are wrapped around one ring to cover the gap between the secondary discharge port 33 and the square plate with a sealing film.

[0042] When adjusting the square plate, remove the sealing film, then loosen the bolts to allow the square plate to rotate. When the square plate is rotated to a suitable angle, tighten the bolts to fix the angle of the square plate. Then wrap the sealing film around the outer wall of the square plate and the secondary discharge port 33, so that the bottom outer edge of the square plate and the bottom outer edge of the secondary discharge port 33 form a square discharge port with a different size than the original, thereby realizing the adjustment of the flatness thickness and size.

[0043] Example 3

[0044] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 The width adjustment mechanism 4 includes a telescopic component 41 and a drive component 42. The telescopic component 41 is disposed on the secondary discharge port 33, and the drive component 42 is connected to the telescopic component 41.

[0045] The telescopic assembly 41 includes a left concave panel 411, a right concave panel 412, and an extension plate 413. Sliding grooves are provided on the front and rear sides of the secondary discharge port 33. The left concave panel 411 and the right concave panel 412 are respectively limited and slidably connected to the front and rear sides of the sliding grooves. The right ends of the left concave panel 411 and the right concave panel 412 are fixedly connected to the extension plate 413.

[0046] The drive assembly 42 includes a motor 421, a bidirectional lead screw 422, and a limiting rod 423. The motor 421 is fixedly installed on the upper rear outer wall of the frame 2. The bidirectional lead screw 422 and the limiting rod 423 are rotatably connected between the upper front and rear supports of the frame 2. The rear end of the bidirectional lead screw 422 is fixedly connected to the output end of the motor 421. The bidirectional lead screw 422 is threadedly connected to the two side extension plates 413 respectively. The limiting rod 423 is slidably connected to the two side extension plates 413 respectively.

[0047] Motor 421 drives bidirectional lead screw 422 to rotate. Bidirectional lead screw 422 drives the extension plates 413 on both sides to move synchronously in opposite directions along limit rod 423, so that the left concave panel 411 and the right concave panel 412 move synchronously in opposite directions to adjust the cross-sectional size of the secondary discharge port 33. The change in the cross-sectional size of the secondary discharge port 33 will affect the amount of material falling onto the feeding assembly in the same time, thereby adjusting the amount of polymer material fed in.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
