Description

Technical Field

[0001] This utility model relates to the technical field of recycled polyester processing equipment, specifically a recycled polyester slitting device for chemical fibers with an anti-adhesion structure. Background Technology

[0002] In the chemical fiber industry, recycled polyester is widely used due to its environmental and cost advantages. In the process of recycled polyester processing, the slitting process is a key step in cutting recycled polyester strips into sizes that meet the requirements of subsequent production.

[0003] A search revealed that patent publication number CN217943903U discloses a pelletizing device for recycling plastic extruded strips, comprising: an upper pressure roller, a lower pressure roller, a cutter holder, and a rotary cutter disc. An extrusion groove is provided between the upper and lower pressure rollers. The rotary cutter disc cuts the plastic extruded strips at the cutter holder outlet when it rotates. The device also includes: a feeding rack with a base plate horizontally arranged along its upper edge. A pressure plate is slidably mounted on the base plate, and a pressure rod is slidably mounted above the feeding rack. An extrusion chamber for pressing several parallel plastic extruded strips is formed between the pressure plate and the base plate. Shaft heads are located on opposite sides of the feeding rack below the base plate, and clamping posts are located on opposite sides of the feeding rack above the base plate. An upward-opening U-shaped groove is located below the frame on the feeding side of the extrusion groove, and a clamping part is located below the frame. The pelletizing device provided by this invention allows operators to pre-arrange and press several plastic extruded strips side-by-side, then quickly feed them to the upper and lower pressure rollers before pelletizing, thus facilitating feeding.

[0004] In actual use, existing recycled polyester slitting devices for chemical fibers generate a large amount of heat due to friction when the slitting blades cut recycled polyester strips at high speed, causing the blade temperature to rise sharply. The blades at high temperatures are prone to sticking to the recycled polyester strips, which not only affects the slitting accuracy but also reduces the slitting efficiency, increases the frequency of downtime for cleaning, and increases maintenance costs. On the other hand, the static electricity generated during the slitting process causes the slitting blades and hollow rollers to attract recycled polyester debris and dust, further aggravating the sticking phenomenon. Therefore, a recycled polyester slitting device for chemical fibers with an anti-sticking structure is designed. Utility Model Content

[0005] In view of the defects or deficiencies of the recycled polyester slitting device for chemical fibers, the purpose of this utility model is to provide a recycled polyester slitting device for chemical fibers with an anti-adhesion structure, which can effectively prevent the recycled polyester strips from melting and sticking together on the slitting mechanism, ensure the continuous and stable slitting process, reduce the number of downtime cleanings, and improve production efficiency.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a recycled polyester slitting device for chemical fibers with an anti-adhesion structure, including a mounting frame, a housing mounted on the top of the mounting frame, a slitting mechanism for slitting recycled polyester strips and an electrostatic elimination component for removing static electricity from the slitting mechanism, a driving component for driving the slitting mechanism on one side of the housing, and a cooling medium flow structure for flowing cooling medium on both sides of the slitting mechanism.

[0008] The slitting mechanism is composed of an upper slitting component and a lower slitting component, with the upper slitting component located above the lower slitting component. Both the upper and lower slitting components are equipped with hollow rollers and mounting sleeves. The mounting sleeves are installed on the circumferential outer wall of the hollow rollers, and both the hollow rollers and the mounting sleeves are located inside the housing. The two ends of the hollow rollers pass through bearings on the outer walls of both sides of the housing and extend to the outside. A driven gear is provided on the circumferential outer wall of one end of the hollow rollers, and the driven gear is located outside the housing. The circumferential outer wall of the mounting sleeve is equipped with slitting blades arranged in a ring array, and the circumferential inner wall of the mounting sleeve is equipped with T-shaped connecting blocks arranged in a ring array. The T-shaped connecting blocks are installed in T-shaped connecting grooves, and the T-shaped connecting grooves are arranged in a ring array on the circumferential outer wall of the hollow rollers.

[0009] Preferably, both ends of the mounting sleeve are provided with fastening plates, and the fastening plates are fixedly connected to the hollow rotating roller by fastening bolts.

[0010] Preferably, the drive assembly is composed of a geared motor and a drive gear, the drive gear is mounted on the output shaft of the geared motor, the drive gear meshes with the driven gear, and the geared motor is mounted on one side of the top of the mounting bracket.

[0011] Preferably, the cooling medium flow structure is composed of a cooling medium input / output pipe and a branch pipe. A first branch pipe is provided on one side of the circumferential outer wall of the branch pipe, and the other end of the first branch pipe is connected to the cooling medium input / output pipe through a pipe joint. A second branch pipe is provided above and below the other side of the circumferential outer wall of the branch pipe, and the other end of the second branch pipe is located in a sealed bearing on the circumferential inner wall of the hollow roller.

[0012] Preferably, the static elimination component is provided with a housing, which is installed on the rear end face of the shell. An installation plate is provided inside the housing, and an ion fan is installed on the rear end face of the installation plate.

[0013] Preferably, an exhaust hood is provided on the rear end face inside the housing, and the interior of the exhaust hood is connected to the ventilation opening on the housing.

[0014] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0015] 1. In this utility model, through a series of coordinated structural arrangements, during the slitting process of recycled polyester strips, the external cooling medium conveying equipment delivers the cooling medium through a cooling medium flow structure to the hollow roller and discharges it from another cooling medium flow structure. When the cooling medium flows inside the hollow roller, it can quickly cool and reduce the temperature of the hollow roller, mounting sleeve, and slitting blades, etc. It can quickly remove the heat generated by the friction between the slitting blades and the recycled polyester strips, keeping the temperature of the slitting blades within a safe threshold. This avoids the situation where the recycled polyester strips melt and stick to the slitting blades due to high temperature, significantly reducing the probability of sticking, ensuring a continuous and stable slitting process, reducing the number of downtime cleanings, and improving production efficiency.

[0016] 2. In this utility model, through a series of coordinated structural arrangements, when this equipment cuts recycled polyester strips, the ion fan is started. The ion fan generates a large amount of airflow with positive and negative charges and blows it toward the surface of the hollow roller, slitting blade and other structures. This neutralizes the charge on the surface of the hollow roller, slitting blade and other structures, thereby eliminating the static electricity on the surface of the hollow roller, slitting blade and other structures. This prevents the secondary adhesion caused by the static adsorption of recycled polyester debris and dust by the hollow roller, slitting blade and other structures. Attached Figure Description

[0042] Working Principle: When in use, with the external power supply connected, during the slitting process of recycled polyester strips, the external cooling medium conveying device delivers the cooling medium through one cooling medium flow structure 300 to the hollow roller 212 and out through another cooling medium flow structure 300. As the cooling medium flows within the hollow roller 212, it rapidly cools the hollow roller 212, the mounting sleeve 213, and the slitting blade 214, quickly removing the heat generated by the friction between the slitting blade 214 and the recycled polyester strips. This maintains the temperature of the slitting blade 214 within a safe threshold, preventing the recycled polyester strips from melting and sticking to the slitting blade 214 due to high temperatures. This significantly reduces the probability of adhesion, ensures a continuous and stable slitting process, reduces the number of downtime cleanings, and improves production efficiency. When slitting recycled polyester strips, the ion fan 620 starts, generating a large amount of airflow with positive and negative charges, which is blown onto the surfaces of structures such as the hollow roller 212 and the slitting blade 214. This neutralizes the charge on the surfaces of the hollow roller 212 and the slitting blade 214, thereby eliminating static electricity on their surfaces and preventing secondary adhesion caused by the static adsorption of recycled polyester debris and dust.
