Description

Technical Field

[0001] The utility model relates to the technical field of material winding, and specifically, relates to a winding device for the production of filter membranes. Background Art

[0002] A filter membrane is a thin film material with a selective separation function. Many tiny pores are distributed on the surface of the filter membrane. The size and distribution of these pores are designed and manufactured according to different uses and requirements. The filter membrane is an important material and tool for realizing operations such as filtration, separation, and purification. In the actual production process, in order to facilitate transportation more conveniently, it is often necessary to repeatedly wind the filter membrane in large quantities.

[0003] After retrieval, a winding device for the production of a porous fiber air filter membrane disclosed in the publication number CN218319671U is roughly described as including a winding frame. A winding roller is installed in the middle of the winding frame. The upper end of the winding frame is fixedly connected to an installation frame. The middle of the upper end of the installation frame is fixedly connected to a support frame. A limiting mechanism is installed at the front of the support frame. The support frame is clamped with an adjusting rod through the limiting mechanism. The lower end of the adjusting rod is fixedly connected to a connecting plate. The lower end of the connecting plate is fixedly connected to an installation frame. Threaded rods are rotatably connected to both sides inside the installation frame, and the two threaded rods are fixedly connected. The beneficial effect of the utility model is that: through the provided combing structure that can drive the threaded rod by a turning handle, so that the threaded rod drives the combing frame and the combing plate to move, it can limit and comb porous fiber air filter membranes with different widths, ensure that when the winding roller winds the porous fiber air filter membrane, the porous fiber air filter membrane is wound neatly, and prevent the porous fiber air filter membrane from shifting during winding, resulting in an uneven winding situation.

[0004] In the above technical solution, although it can ensure that when the winding roller is working, the filter membrane does not shift during the winding process and the filter membrane is wound neatly, in the actual production process, as the winding shaft rotates continuously, the thickness and surface area of the filter membrane on it gradually increase, but the angle of the filter membrane passing between each roller shaft remains unchanged. This results in the winding tension of the filter membrane continuously increasing as the thickness of the filter membrane increases. When the rotational speed adjustment of the winding roller is not synchronized, it is extremely easy to cause damage to the filter membrane, greatly reducing the production efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a winding device for the production of filter membranes, and solve the problem in the prior art that in the actual production process, as the winding shaft rotates continuously, the thickness and surface area of the filter membrane on it gradually increase, but the angle of the filter membrane passing between each roller shaft remains unchanged. This results in the winding tension of the filter membrane continuously increasing as the thickness of the filter membrane increases. When the rotational speed adjustment of the winding roller is not synchronized, it is extremely easy to cause damage to the filter membrane, greatly reducing the production efficiency.

[0006] The utility model provides the following technical solution: a winding device for producing a filter membrane, which includes a box body. A stacking box is arranged on one side of the box body. The box body includes a bottom plate. An inlet table is arranged on the top end of the bottom plate, and the inlet table is located on one side of the stacking box. A circular roller is rotatably connected to the middle of the inlet table. A winding mechanism is arranged on the top end of the bottom plate on one side of the circular roller.

[0007] By adopting the above scheme, the stacking box can release heat and static electricity of the produced filter membrane, avoiding damage or adsorption during the winding process, and improving the efficiency.

[0008] As a preference of the above technical solution, the winding mechanism includes support frames symmetrically arranged on the top end of the bottom plate. A fixed roller is rotatably connected to the inner side wall of the support frame. Convex blocks are arranged on the outer wall of the fixed roller. First cylinders are symmetrically arranged on the top end of the bottom plate on one side of the fixed roller. A lifting platform is fixedly connected to the telescopic end of the first cylinder. A first movable roller is rotatably connected to the inner wall of the lifting platform, and a first receiver is fixedly connected to the outer wall of the lifting platform.

[0009] By adopting the above scheme, the support frame can provide sufficient stability for the fixed roller, so that it will not tilt or shake during rotation, thus affecting the winding quality. The convex blocks arranged on the outer wall of the fixed roller can provide sufficient friction force. The first cylinder can drive the lifting platform arranged at its telescopic end to move longitudinally, and then timely adjust the longitudinal height of the first movable roller through the signal received by the first receiver.

[0010] As a preference of the above technical solution, a support is arranged on the top end of the bottom plate, and the support is located on one side of the first movable roller. A transmission roller is rotatably connected to the inner wall of the support. Second cylinders are symmetrically arranged on the top end of the bottom plate, and the second cylinders are located on one side of the transmission roller. A connecting platform is arranged at the telescopic end of the second cylinder. A second movable roller is rotatably connected to the inner wall of the connecting platform, and a second receiver is fixedly connected to the outer wall of the connecting platform.

[0011] By adopting the above scheme, since a transmission roller is rotatably connected to the inner wall of the support and there is a height difference between the transmission roller and the movable rollers on both sides, a certain pulling force can be brought to the filter membrane during rotation. The second cylinder can control the longitudinal displacement of the connecting platform by receiving signals from the second receiver in real time.

[0012] As a preference of the above technical solution, a winding roller assembly is arranged on the bottom plate on one side of the second movable roller. The winding roller assembly includes a support seat arranged on the top end of the bottom plate and a pressure sensor arranged on the top end of the support seat. A support platform is fixedly connected to the top end of the pressure sensor. A notch is formed on the outer side wall of the support platform, and a baffle is slidably connected inside the notch.

[0013] Adopting the above solution, the winding efficiency can be improved through the winding roller assembly. The pressure sensors of the support seats can transmit signals to the first receiver and the second receiver according to the change of the weight on them, enabling the two to lift and lower in real time to change the winding angle of the filter membrane.

[0014] As a preference of the above technical solution, a rotating table is fixedly connected to one side of the notch of the support table. A groove is provided at the corresponding position of the outer wall of the rotating table and the notch. A winding roller shaft is rotatably connected inside the rotating table.

[0015] Adopting the above solution, through the rotating table, the winding roller shaft can rotate inside it. The groove provided on the rotating table can facilitate the removal of the wound filter membrane. The winding roller shaft can be well limited by the setting of the baffle.

[0016] As a preference of the above technical solution, convex balls are uniformly arranged on the outer wall of the winding roller shaft. A driving motor is arranged at the top end of the bottom plate and is located on one side of the winding roller shaft. A clamping plate is sleeved at the output end of the driving motor. A clamping seat is slidably connected to the outer wall of the clamping plate. A clamping block is arranged on one side of the outer end of the winding roller shaft and is located at the clamping seat.

[0017] Adopting the above solution, the convex balls on the winding roller shaft can bring certain friction to it, enabling the winding to be tighter. The driving motor can provide the power for the winding roller assembly. The clamping plate sleeved at the output end of the driving motor can be clamped with the clamping block at the outer end of the winding roller shaft through the slidably connected clamping seat on it. Then the driving motor can drive the winding roller shaft to rotate. When the winding is completed, the clamping seat can be slid to separate it from the clamping block, and the other end of the winding roller shaft can be lifted, and then the winding roller shaft can be taken out, so as not to affect the removal of the filter membrane on the winding roller shaft.

[0018] As a preference of the above technical solution, a numerical control operator is arranged on the outer side wall of the box body, and a PLC controller is arranged on the outer wall of the box body at the position of the winding roller assembly.

[0019] Adopting the above solution, the winding device can be adjusted through the numerical control operator, thereby improving the winding efficiency. The PLC controller can convert and transmit the signals of the pressure sensors to the first receiver and the second receiver.

[0020] Compared with the prior art, the beneficial effects of the utility model are as follows: through the cooperation of the first movable roller, the second movable roller and the winding roller assembly, the tension of the winding roller during the winding process can be reduced. When the filter membrane on the winding roller shaft gradually thickens during winding, its weight naturally increases. Therefore, the pressure sensor receives the signal and transmits it to the receivers of the first movable roller and the second movable roller. As the two move up and down through the cylinders connected to their bottoms, the angle between the roller shafts is reduced, enabling the filter membrane to be wound more smoothly, improving the production efficiency and reducing the loss of the filter membrane material at the same time.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0029] As shown in Figure 1 , the utility model provides a technical solution: a winding device for producing a filter membrane, which includes a box body 1. A stacking box 101 is arranged on one side of the box body 1. The box body 1 includes a bottom plate 102. An inlet table 103 is arranged at the upper end of the bottom plate 102, and the inlet table 103 is located on one side of the stacking box 101. A circular roller 104 is rotatably connected in the middle of the inlet table 103. A winding mechanism 2 is arranged at the upper end of the bottom plate 102 on one side of the circular roller 104. By arranging the stacking box 101, the produced filter membrane can release heat and static electricity, avoiding damage or adsorption during the winding process, and improving the efficiency.

[0030] As shown in Figure 2 and Figure 3 , the winding mechanism 2 includes support frames 201 symmetrically arranged at the upper end of the bottom plate 102. A fixed roller 202 is rotatably connected to the inner side wall of the support frame 201. A convex block 203 is arranged on the outer wall of the fixed roller 202. First cylinders 204 are symmetrically arranged at the upper end of the bottom plate 102 on one side of the fixed roller 202. A lifting table 205 is fixedly connected to the telescopic end of the first cylinder 204. A first movable roller 206 is rotatably connected to the inner wall of the lifting table 205, and a first receiver 207 is fixedly connected to the outer wall of the lifting table 205. The support frame 201 can provide sufficient stability for the fixed roller 202, so that it will not tilt or shake during rotation, thus affecting the winding quality. The convex block 203 arranged on the outer wall of the fixed roller 202 can provide sufficient friction. The first cylinder 204 can drive the lifting table 205 arranged at its telescopic end to move longitudinally, and then timely adjust the longitudinal height of the first movable roller 206 through the signal received by the first receiver 207.

[0031] As shown in Figure 3 , a support 208 is arranged at the upper end of the bottom plate 102, and the support 208 is located on one side of the first movable roller 206. A transmission roller 209 is rotatably connected to the inner wall of the support 208. Second cylinders 210 are symmetrically arranged at the upper end of the bottom plate 102, and the second cylinders 210 are located on one side of the transmission roller 209. A connecting table 211 is arranged at the telescopic end of the second cylinder 210. A second movable roller 212 is rotatably connected to the inner wall of the connecting table 211, and a second receiver 213 is fixedly connected to the outer wall of the connecting table 211. Since the transmission roller 209 is rotatably connected to the inner wall of the support 208 and there is a height difference between the transmission roller 209 and the movable rollers on both sides, a certain pulling force can be brought to the filter membrane during rotation. The second cylinder 210 can control the longitudinal displacement of the connecting table 211 by receiving signals from the second receiver 213 in real time.

[0032] As shown in Figures 4 - 6As shown in the figure, a winding roller assembly 3 is arranged on one side of the bottom plate 102 relative to the second movable roller 212. The winding roller assembly 3 includes a support seat 301 arranged at the upper end of the bottom plate 102 and a pressure sensor 302 arranged at the upper end of the support seat 301. The model of the pressure sensor 302 is XL31PX intelligent pressure sensor. A support platform 303 is fixedly connected to the upper end of the pressure sensor 302. A notch 304 is formed on the outer side wall of the support platform 303. A baffle 305 is slidably connected inside the notch 304. The winding roller assembly 3 can improve the winding efficiency. The pressure sensor 302 of the support seat 301 can transmit signals to the PLC controller 106 as the weight on it changes, and the signals are converted and transmitted to the first receiver 207 and the second receiver 213, so that the two can lift and lower in real time to change the winding angle of the filter membrane. A rotating platform 306 is fixedly connected to the support platform 303 on one side of the notch 304. A groove 307 is formed on the outer wall of the rotating platform 306 corresponding to the notch 304. A winding roller shaft 308 is rotatably connected inside the rotating platform 306. The rotating platform 306 can make the winding roller shaft 308 rotate inside it. The groove 307 formed on the rotating platform 306 can more conveniently take out the wound filter membrane. The baffle 305 can well limit the winding roller shaft 308. Convex balls 309 are uniformly arranged on the outer wall of the winding roller shaft 308. A driving motor 310 is arranged at the upper end of the bottom plate 102, and the driving motor 310 is located on one side of the winding roller shaft 308. A clamping plate 311 is sleeved on the output end of the driving motor 310. A clamping seat 312 is slidably connected to the outer wall of the clamping plate 311. A clamping block 313 is arranged on one side of the outer end of the winding roller shaft 308 relative to the clamping seat 312. The convex balls 309 on the outer wall of the winding roller shaft 308 can bring certain friction to it, enabling the winding to be tighter. The driving motor 310 can provide the power for the winding of the winding roller assembly 3. The clamping plate 311 sleeved on the output end of the driving motor 310 can be clamped with the clamping block 313 at the outer end of the winding roller shaft 308 through the slidably connected clamping seat 312 on it. Thus, the driving motor 310 can drive the winding roller shaft 308 to rotate. When the winding is completed, the clamping seat 312 can be slid to separate it from the clamping block 313, and the other end of the winding roller shaft 308 can be lifted, and then the winding roller shaft 308 can be taken out, so as not to affect the taking out of the filter membrane on the winding roller shaft 308. A numerical control operator 105 is arranged on the outer side wall of the box body 1. The winding mechanism 2 can be adjusted through the numerical control operator 105, thereby improving the winding efficiency.

[0033] Working principle: The filter membrane can simply release the heat generated during its production through the stacking box 101 at the front end of the box body 1, so that it will not be damaged due to overheating during the winding process. The filter membrane passes through the lower surface of the fixed roller 202, then through the upper surface of the first movable roller 206, then through the lower surface of the driving roller 209, then through the upper surface of the second movable roller 212, and finally is wound by the winding roller shaft 308. As the filter membrane on the winding roller shaft 308 becomes thicker, its own weight gradually increases. Therefore, when the gravity is transmitted to the pressure sensor 302, it transmits a release signal to the PLC controller 106. The PLC controller 106 converts and transmits the signal to the first receiver 207 and the second receiver 213. When receiving the signal, it will cause the first cylinder 204 and the second cylinder 210 to drive the first movable roller 206 and the second movable roller 212 to adjust their own heights, thereby adjusting the angle of the filter membrane passing through them. When the angle becomes smaller, the tension of the filter membrane passing through the roller shaft also decreases. When the winding work is completed, the baffle 305 in the sliding notch 304 can open the upper space of the groove 307, and then the sliding clamp seat 312 separates the clamping block 313 at the outer end of the winding roller shaft 308 from it, and the filter membrane on the winding roller shaft 308 can be removed to complete the winding work.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
