Description
Technical Field
[0001] This utility model belongs to the technical field of hollow fiber membrane stretching equipment, and in particular relates to a hollow fiber membrane stretching equipment with uniform tension. Background Technology
[0002] Hollow fiber membrane stretching equipment is a highly efficient and environmentally friendly production equipment specifically designed for the production of hollow fiber membranes. As a key piece of equipment in the production of hollow fiber membranes, its unique design and efficient production capabilities provide enterprises with excellent production solutions.
[0003] Existing hollow fiber membrane stretching equipment typically lacks a limiting function during the stretching process, leading to vibration of the hollow fiber membrane. When the vibration amplitude is large, it can cause the hollow fiber membrane to loosen, resulting in uneven tension and affecting the production quality of the hollow fiber membrane. Therefore, we propose a hollow fiber membrane stretching equipment with uniform tension. Utility Model Content
[0004] The purpose of this invention is to provide a hollow fiber membrane stretching device with uniform tension. By setting a limiting component, specifically, after the hollow fiber membrane is placed in the limiting seat, the movement space of the hollow fiber membrane is restricted by the limiting seat during stretching, which can reduce the shaking of the hollow fiber membrane during the stretching process. At the same time, the limiting groove on the limiting plate can also play a certain limiting role, further reducing shaking, thereby preventing uneven stress on the hollow fiber membrane and improving the production quality of the hollow fiber membrane. This invention solves the problem that existing hollow fiber membrane stretching devices usually do not have a limiting function when stretching hollow fiber membranes, which causes the hollow fiber membrane to shake during stretching. When the shaking amplitude is large, it will cause the hollow fiber membrane to loosen, resulting in uneven tension on the hollow fiber membrane and affecting the production quality of the hollow fiber membrane.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] Please see Figure 1-5As shown, this utility model is a hollow fiber membrane stretching device with uniform tensile force, including a base 1. A limiting component 11 is provided at the center of the top of the base 1. The limiting component 11 includes a limiting seat 111, which has several placement slots inside. A cover plate 112 is in contact with the top of the limiting seat 111. A handle 113 is fixedly connected to the top of the cover plate 112. Insert rods are fixedly connected to the four corners of the bottom of the cover plate 112 and are inserted into the top of the limiting seat 111. An auxiliary roller 14 is provided on the right side of the limiting seat 111. A support frame 141 is rotatably connected to the front and back of the auxiliary roller 14. The bottom of the support frame 141 is fixedly connected to the top of the base 1. A limiting plate 142 is fixedly connected to the right side of the support frame 141. Several slots are provided on the right side of the limiting plate 142. The limiting groove 143, through the setting of the limiting component 11, specifically, after the hollow fiber membrane is placed in the limiting seat 111, when it is stretched, the hollow fiber membrane is restricted in its movement space by the limiting seat 111, which can reduce the shaking of the hollow fiber membrane during the stretching process. At the same time, the limiting groove 143 on the limiting plate 142 can also play a certain limiting role, further reducing the shaking, thereby preventing uneven force on the hollow fiber membrane and improving the production quality of the hollow fiber membrane. A stabilizing roller 12 is set on the upper left side of the base 1. The front and back of the stabilizing roller 12 are rotatably connected to the support block 121. The bottom of the support block 121 is fixedly connected to the top of the base 1. The stabilizing roller 12 is used to position the hollow fiber membrane through the limiting plate set on its surface. The function of the auxiliary rollers 13 and 14 is to allow the hollow fiber membrane to be smoothly inserted into the placement slot on the limiting seat 111. An auxiliary roller 13 is provided on the left side of the limiting seat 111. Support blocks 131 are rotatably connected to the front and back of the auxiliary roller 13. The bottom of the support blocks 131 is fixedly connected to the top of the base 1. The cooperation of the auxiliary rollers 13 and 14 provides support for the hollow fiber membrane, making its movement more stable. A tension adjusting assembly 15 is provided on the right side of the auxiliary roller 14. The tension adjusting assembly 15 includes a movable frame 151, the bottom of which contacts the top of the base 1. An adjusting roller 152 is rotatably connected inside the movable frame 151. A stabilizing frame 153 is fixedly connected to the front and back of the movable frame 151. The stabilizing frame 153 slides inside. A sliding rod 154 is connected, with connecting blocks 541 fixedly connected to both the left and right sides of the sliding rod 154. The side of the connecting block 541 closest to the base 1 is fixedly connected to the surface of the base 1. A tension adjustment component 15 is provided; specifically, the moving frame 151 adjusts the position of the adjusting roller 152 during movement. When the adjusting roller 152 moves to the left, the limiting plate pushes the hollow fiber membrane to tighten it. When the adjusting roller 152 moves to the right, the limiting plate does not push the hollow fiber membrane, allowing the hollow fiber membrane to relax. This adjusts the tension of the hollow fiber membrane during stretching, ensuring that the hollow fiber membrane remains in contact with the adjusting roller 152 during stretching, thereby further improving the uniformity of force distribution. An opening is provided on the right side of the base 1, with a fixing block 155 fixedly connected to the inner wall of the opening.A threaded rod 551 is rotatably connected inside the fixed block 155. A handle 552 is fixedly connected to the right side of the threaded rod 551. The left side of the threaded rod 551 is rotatably connected to the left side of the inner wall of the opening. An internally threaded block 156 is fixedly connected to the bottom of the movable frame 151. The outer surface of the internally threaded block 156 contacts the inner wall of the opening. The left side of the threaded rod 551 passes through the internally threaded block 156 and extends to the outside. The outer surface of the threaded rod 551 is threadedly connected to the inner wall of the internally threaded block 156. Rotating the handle 552 causes the threaded rod 551 to rotate, and the internally threaded block 156 will then rotate. The threaded rod 551 moves left or right, while the internal threaded block 156 drives the moving frame 151 to move together, thereby adjusting the position of the adjusting roller 152. The limiting groove 143 on the limiting plate 142 corresponds to the placement groove inside the limiting seat 111. Limiting discs are fixedly connected to the outer surfaces of the stabilizing roller 12 and the adjusting roller 152. The limiting discs correspond to the limiting groove 143 and the limiting seat 111. Because the limiting discs correspond to the limiting groove 143 and the limiting seat 111, the hollow fiber membrane can be transported more stably.
[0026] One specific application of this embodiment is:
[0027] Pulling handle 113 causes cover plate 112 to be pulled upwards, disengaging the insert at the bottom of cover plate 112 from the limiting seat 111. The top of limiting seat 111 is then opened. The hollow fiber membrane is then passed from the top of the limiting disc on stabilizing roller 12 to the bottom of auxiliary roller 13, then into limiting seat 111, and finally out from the top of auxiliary roller 2 14, engaging with the limiting groove 143 on limiting plate 142. It then passes through the bottom of the limiting disc on adjusting roller 152 and connects to the stretching device. Cover plate 112 is then connected to the top of limiting seat 111 via the bottom insert, sealing the top of limiting seat 111. At this point, the hollow fiber membrane is stretched by the stretching device. The limiting seat 111 restricts the movement of the hollow fiber membrane, reducing vibration during stretching. Simultaneously, the limiting groove 143 on limiting plate 142 also provides some limiting function. This further reduces vibration, preventing uneven stress on the hollow fiber membrane and improving its production quality. By rotating the handle 552, the threaded rod 551 rotates, causing the inner threaded block 156 to move left or right on the threaded rod 551. Simultaneously, the inner threaded block 156 drives the moving frame 151 to move together, while the stabilizing frame 153 slides on the slide rod 154, limiting the movement of the moving frame 151 and making it move in a straight line. At the same time, the position of the adjusting roller 152 is adjusted. When the adjusting roller 152 moves to the left, the limiting plate pushes the hollow fiber membrane to tighten. When the adjusting roller 152 moves to the right, the limiting plate does not push the hollow fiber membrane, allowing it to relax. This adjusts the tension of the hollow fiber membrane during the stretching process, ensuring that the hollow fiber membrane is always in contact with the adjusting roller 152 during stretching, thereby further improving the uniformity of stress.
