Description

Technical Field

[0001] This utility model relates to a device for breaking adhesion, specifically a device for breaking adhesion in pulp raw materials, belonging to the field of raw material feeding technology in fiber production. Background Technology

[0002] Pulp is a cellulose raw material obtained through the chemical treatment of plant fibers, primarily used in the manufacture of man-made fibers such as viscose and lyocell. Its raw material sources include wood, cotton linters, and grasses. It undergoes processes such as cooking and bleaching to remove lignin and non-cellulose components. The final pulp product is typically in sheet form (also known as "pulp paperboard"), which is stacked and packaged to form pulp bales. Because pulp is susceptible to moisture and inherently contains a certain amount of water, the inner layers tend to stick together during storage or transportation. In the production of staple fibers, excessive stickiness of the raw materials hinders pulp preparation, affecting the quality and stability of subsequent staple fiber production.

[0003] To ensure accurate metering and feeding of pulp raw materials, it is necessary to break up the adhesive layers, i.e., eliminate the inner layers of sticky material. Currently, the common method is manual breaking up of the adhesive layers, where workers use axes or other tools to manually chop the pulp to loosen it. However, to meet the needs of the production line (e.g., batch processing, large-scale, orderly, and stable feeding), this method requires four employees, resulting in high labor intensity and high human resource costs. Furthermore, the frequent use of axes and other tools poses significant safety hazards; and the manual breaking up of adhesive layers is not very effective in achieving the desired pulp looseness.

[0004] Therefore, there is a need for a device that can effectively break up the stickiness of pulp raw materials, is safe, and can reduce labor intensity and save costs. Summary of the Invention

[0005] To address the problems of poor de-adhesion effect, high strength, and high cost of pulp raw materials in existing technologies, a de-adhesion device for pulp raw materials is proposed. In this technical solution, the de-adhesion of pulp raw materials is fully automated through the installation of inclined and horizontal push components on the frame, improving looseness, reducing labor intensity, and lowering human resource costs. Finally, uniform feeding at the discharge port ensures stable pulp concentration, reducing the difficulty of subsequent pulp preparation.

[0006] To achieve the above technical objectives, the following technical solution is proposed: The purpose of this technical solution is to provide: a device for breaking adhesion of pulp raw materials, including a frame and a slanting push assembly and a transverse push assembly mounted on the frame, and a placement platform for placing pulp raw materials is provided below the frame; The inclined push assembly includes a left inclined plate and a right inclined plate. The left inclined plate is connected to the frame through a left linear drive mechanism I, realizing the linear movement of the left inclined plate; the right inclined plate is connected to the frame through a right linear drive mechanism I, realizing the linear movement of the right inclined plate; the left inclined plate is located on the left side of the placement table, and the right inclined plate is located on the right side of the placement table. The left and right inclined plates are set in parallel, and a space for the pulp raw material to be tilted and misaligned is formed between the left and right inclined plates, realizing the initial breaking of adhesion of the pulp raw material; The transverse push assembly includes a left push plate and a right push plate. The left push plate is connected to the frame via a left linear drive mechanism II, enabling linear movement of the left push plate. The right push plate is connected to the frame via a right linear drive mechanism II, enabling linear movement of the right push plate. The left push plate is located on the left side of the placement table, and the right push plate is located on the right side of the placement table. The left and right push plates are arranged in parallel, forming an arc-shaped space between them where the pulp raw material arches upwards, thus achieving secondary breaking and bonding of the pulp raw material.

[0007] Furthermore, the placement platform is located between the raw material conveyor and the unloading machine. The raw material conveyor is located in front of the workstation of the placement platform, and the unloading machine is located behind the workstation of the placement platform. A continuous passage for conveying, breaking adhesion, and unloading pulp raw materials is formed between the raw material conveyor, the placement platform, and the unloading machine.

[0008] Furthermore, the raw material conveyor is a chain conveyor.

[0009] Furthermore, photoelectric sensors are installed on the frame near the placement table. Preferably, there are four photoelectric sensors, evenly distributed on the outside of the placement table, to detect the pulp raw material on the placement table and then stop its conveying. Then, the adhesion is broken up. After the adhesion is broken up, it is conveyed to the feeding machine.

[0010] Furthermore, the left linear drive mechanism I, right linear drive mechanism I, left linear drive mechanism II, and right linear drive mechanism II are all electric cylinders.

[0011] Furthermore, each of the electric cylinders is equipped with a braking mechanism on its rear side.

[0012] Furthermore, both the left and right inclined plates are inclined, and the lengths of both the left and right inclined plates are greater than or equal to the height of the pulp raw material.

[0013] Furthermore, both the left and right push plates are vertically arranged, and the lengths of both the left and right push plates are greater than or equal to the height of the pulp raw material.

[0014] Furthermore, the frame is also equipped with a clamping mechanism, which is located directly above the placement platform; the clamping mechanism is connected to an upper linear drive mechanism, which drives the clamping mechanism to move longitudinally.

[0015] Furthermore, the upper linear drive mechanism is a pressure cylinder.

[0016] Furthermore, a telescopic push rod is provided directly below the placement platform, and a channel for the push rod to retract and extend is provided on the placement platform, with the channel located at the center of the placement platform. This arrangement, during the secondary breaking of adhesion in the pulp raw material, also applies an upward force, thereby ensuring that the pulp raw material is arched upwards in an arc shape, ultimately achieving the breaking of adhesion.

[0017] The positional relationships such as "below", "above", "left side", "right side", "between", "outer side", "tilted", "directly above", and "directly below" involved in this technical solution are defined according to the actual usage conditions and are conventional terms in this technical field, as well as conventional terms used by those skilled in the art in actual use.

[0018] In the description of this technical solution, it should be noted that, unless otherwise explicitly specified and limited, the terms "setting" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The beneficial technical effects of adopting this technical solution are as follows: I. This utility model achieves automated operation of breaking the stickiness of pulp raw materials by setting up the inclined push component and the horizontal push component of the frame, which improves the looseness, reduces labor intensity and reduces human resource costs; finally, uniform feeding is achieved at the feeding port to ensure the stability of pulp concentration and reduce the difficulty of pulp preparation in subsequent processes. Second, this utility model ensures that after the pulp raw materials are broken up and sticky, assembly line operation can be realized, greatly improving work efficiency; Third, based on this utility model, the pulp raw material has a certain degree of looseness, and 2-3 sheets can be evenly fed at the feeding port each time, ensuring the stability of the pulp concentration in subsequent processes.

The left inclined plate 31 and the right inclined plate 32 are arranged in parallel, and a space for the pulp raw material 1 to be tilted and misaligned is formed between the left inclined plate 31 and the right inclined plate 32 to realize the initial breaking of adhesion of the pulp raw material 1. The transverse push assembly includes a left push plate 35 and a right push plate 36.

The left push plate 35 is located on the left side of the placement table 30, and the right push plate 36 is located on the right side of the placement table 30. The left push plate 35 and the right push plate 36 are arranged parallel to each other, forming an arc-shaped and upward-arched space between the left push plate 35 and the right push plate 36, achieving secondary breaking of adhesion in the pulp raw material 1 (e.g., ...). Figure 6 (As shown).

[0023] Example 2 Based on Embodiment 1, this embodiment further limits the arrangement of the placement platform 30 to further illustrate the technical solution.

[0024] The placement platform 30 is located between the raw material conveyor 2 and the unloading machine, such as... Figure 1 As shown, the raw material conveyor 2 is located in front of the workstation of the placement table 30, and the unloading machine is located behind the workstation of the placement table 30. The raw material conveyor 2, the placement table 30 and the unloading machine form a continuous passage for conveying, breaking adhesion and unloading pulp raw material 1.

[0025] In one specific implementation, the raw material conveyor 2 is a chain conveyor.

[0026] In addition, photoelectric sensors 4 are provided on the frame 39 of the placement table 30. Preferably, there are four photoelectric sensors 4, which are evenly distributed on the outside of the placement table 30 to detect the pulp raw material 1 on the placement table 30 and then stop its conveying. Then, the adhesion is broken. After the adhesion is broken, it is conveyed to the feeding machine.

[0027] Example 3 Based on Examples 1-2, this example further defines the linear drive mechanism to further illustrate the technical solution.

[0028] Left linear drive mechanism I 33, right linear drive mechanism I 34, left linear drive mechanism II 37, and right linear drive mechanism II 38 are all electric cylinders. Preferably, a brake mechanism 5 is provided on the rear side of each electric cylinder.
