Description

Technical Field

[0001] This utility model relates to the technical field of sofa processing equipment, and in particular to a feeding device for a cotton shredder used in sofa production. Background Technology

[0002] In sofa production, the cotton shredder is a key piece of equipment that processes raw materials such as cotton into suitable shreds for filling. Its feeding mechanism has a crucial impact on the efficiency and quality of the entire shredding process. Traditional cotton shredder feeding devices often have several shortcomings. For example, it is difficult to accurately control the feeding speed and uniformity of the raw materials during the feeding process, often resulting in large accumulations of raw materials or feeding interruptions. This not only leads to unstable workload for the cotton shredder, easily causing equipment failures such as blockages and motor overload, but also seriously affects the quality of the shredded cotton, resulting in inconsistent cotton size and failing to meet the high standards required for sofa filling.

[0003] Moreover, traditional feeding devices are extremely unsuitable for cotton materials of different forms (such as block, sheet, and filament) and different moisture levels. Filamentous cotton materials are prone to getting tangled on the feeding components, and cotton materials with higher moisture levels will stick to the surface of the device. These problems not only limit the range of cotton materials that can be processed, but also force companies to carry out additional pre-treatment processes on the cotton materials before feeding, which increases production costs and production cycles.

[0004] Therefore, this utility model proposes a feeding device for a cotton shredder used in sofa production to solve the above problems.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings mentioned in the background art and to propose a feeding device for a cotton shredder used in sofa production.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cotton shredder feeding device for sofa production, comprising a cotton shredder body, a drive motor, a main shaft, a feeding hopper, a feeding component one, two feeding components two, a transmission component one, a transmission component two, and a transmission component three;

The feed hopper is fixedly installed on the top of the cotton shredder body and connected to the feed inlet of the cotton shredder body. The first feed assembly and two second feed assemblies are all arranged inside the feed hopper, and the two second feed assemblies are symmetrically arranged based on the first feed assembly. The first transmission assembly is located on the front side of the cotton shredder body and connected to the main shaft and the first feed assembly. The second transmission assembly is located on the first feed assembly. The third transmission assembly is located on the first feed assembly and connected to the two second feed assemblies.

Mounting rollers are fixedly mounted on both rotating shafts, and multiple strip plates are fixedly mounted on both mounting rollers. Multiple rake teeth are provided on each of the multiple strip plates.

[0010] Preferably, the multiple rake teeth located on the two mounting rollers are arranged in an alternating manner.

[0011] Preferably, the second feeding assembly includes two conveying shafts, two conveying rollers, and a conveyor belt. The feeding hopper has two mounting slots and two strip openings. Conveying shafts are rotatably installed in the mounting slots and strip openings on the same side.

[0017] Preferably, the cross-section of the guide plate is diamond-shaped.

[0018] The beneficial effects of this utility model are:

[0019] The feeding component 1 improves the feeding efficiency of the cotton shredder.

[0030] Reference Figure 1-4 A feeding device for a cotton shredder used in sofa production includes a cotton shredder body 1, a drive motor 12, a main shaft 11, and a feeding hopper 2. The drive motor 12 is fixedly installed on the rear side of the cotton shredder body 1. The main shaft 11 is rotatably installed on the cotton shredder body 1 and axially fixedly connected to the output shaft of the drive motor 12. The feeding hopper 2 is fixedly installed on the top of the cotton shredder body 1 and communicates with the feed inlet of the cotton shredder body 1. Two parallel rotating shafts 3 are rotatably installed on the inner walls of the front and rear sides of the feeding hopper 2. Both rotating shafts 3 are fixedly mounted on... The machine is equipped with mounting rollers 31, and multiple strip plates 32 are fixedly mounted on each of the two mounting rollers 31. Multiple rake teeth 321 are provided on each of the multiple strip plates 32. When the rotating shaft 3 rotates, the mounting rollers 31 can be controlled to drive the strip plates 32 to rotate around the rotating shaft 3. In this way, the material can be moved with the cooperation of multiple rake teeth 321. In order to move the raw material towards the feed port of the cotton shredder body 1 while avoiding motion interference, the multiple rake teeth 321 on the two mounting rollers 31 are staggered.

[0031] The feed hopper 2 has two mounting slots and two strip openings. Conveying shafts 4 are rotatably mounted in the mounting slots and strip openings on the same side. Conveying rollers 41 are fixedly sleeved on both conveying shafts 4. The same conveyor belt 42 is drivenly connected to the two conveying rollers 41, which can convey the material entering the feed hopper 2 to the feed port of the cotton shredder body 1. In order to increase the friction between the material and the raw material, thereby ensuring the efficiency of material feeding, the side of the conveyor belt 42 away from the conveying rollers 41 is roughened.

[0032] A pulley 5 and a pulley 51 are fixedly mounted on the main shaft 11 and one of the rotating shafts 3, respectively. The same belt 52 is connected to the pulley 5 and the pulley 51, which can control the rotation of one of the rotating shafts 3 when the main shaft 11 rotates. The front ends of the two rotating shafts 3 extend to the front side of the feed hopper 2 and are respectively fixedly mounted with gears 33. The two gears 33 mesh with each other, which can keep the two rotating shafts 3 rotating synchronously in opposite directions. The support shaft near the rotating shaft 3 and the rotating shaft 3 extend to the front side of the feed hopper 2 and are respectively fixedly mounted with pulleys 6. The same belt 61 is connected to the two pulleys 6, which can drive the support shaft to rotate when the rotating shaft 3 rotates.

[0033] In this embodiment, in order to guide the raw materials entering the feed hopper 2, and to guide the raw materials after they enter the feed hopper 2, the same guide plate 21 is fixedly installed on the inner walls of the front and rear sides of the feed hopper 2, and the cross section of the guide plate 21 is set in a rhombus shape.

[0034] Working Principle: In operation, first connect the power supply and start the drive motor 12. The drive motor 12 controls the rotation of the main shaft 11. The main shaft 11 drives one of the rotating shafts 3 to rotate through the cooperation of pulley 5, belt 52, and pulley 51. The two rotating shafts 3 can rotate synchronously in opposite directions through the cooperation of two gears 33. Then, under the transmission of pulley 61 and belt 61, the corresponding support shaft 4 can be controlled to rotate. Raw materials are placed into the feed hopper 2 and fall onto the conveyor belt 42 under gravity. Simultaneously, some material is diverted by the guide plate 21 and flows towards the two conveyor belts 42. Driven by the support shaft 4 and the conveyor roller 41, the conveyor belt 42 propels the raw materials towards the feed inlet of the cotton shredder body 1. The conveying process utilizes the rough surface design of the conveyor belt 42, which generates significant friction with the raw material. This ensures that the raw material is stably and continuously conveyed into the working range of the rake teeth 321. Simultaneously, as the rotating shaft 3 rotates, the mounting roller 31 and the strip plate 32 mounted on the rotating shaft 3 also rotate. This allows the rake teeth 321 to agitate the raw material as it rotates around the rotating shaft 3, ensuring that the raw material enters the cotton shredder body 1 evenly and continuously. The staggered arrangement of the rake teeth 321 avoids motion interference and ensures the smoothness of the feeding process. Furthermore, the diamond-shaped cross-section design of the guide plate 21 optimizes the flow path of the raw material, reduces the accumulation and blockage of the raw material in the feed hopper, and further improves the feeding efficiency.

[0035] The above provides a detailed description of the feeding device for a cotton shredder used in sofa production according to this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
