Description

Technical Field

[0001] The invention relates to the technical field of PET films, and in particular to an energy-saving circulating drying device for ultrafiltration membrane production. Background Art

[0002] During the processing of ultrafiltration membrane, the membrane embryo will undergo a water bath process to wash away impurities or dust on it. After the water bath, it will be wiped dry with upper and lower cloths. During the wiping process, it often cannot be wiped dry, which affects the subsequent molding work.

[0003] Chinese patent CN216522879U discloses an energy-saving circulating drying box for PET film production. Although the object of its production and processing is PET film, in the circulating process part, the processing steps of PET film and ultrafiltration membrane are basically the same, and the production steps can be understood based on this. The drying box guides the PET film from the feed port into the drying box through the support roller and the movable seat, and the hot air in the drying box can be recycled through the heating plate and the drying box, so as to better dry the PET film, and then it is easy to lead to the outside from the discharge port of the drying box. However, in order to ensure a better drying environment during use, the drying box must maintain good sealing. After the PET film is guided into the drying box by the external support roller, it may not be able to accurately move to the discharge port and move to the outside of the drying box, so that the PET film that has completed the drying process cannot leave the drying box. Therefore, this solution also has the same problem in ultrafiltration membrane processing. Summary of the invention

[0047] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] See also Figures 1 to 19 As shown, an energy-saving circulation drying device for ultrafiltration membrane production includes a base frame 1, a drying box 2 fixedly arranged on the base frame 1, a drying box 3 fixedly arranged on the base frame 1 and an auxiliary stick 4 fixedly arranged on the drying box 2, and also includes a first linear motion component 5, a guide frame 6, a clamping component 7 and a first pressure sensor. The two ends of the drying box 2 are respectively provided with a feed port 2a and a discharge port 2b. The first linear motion component 5 is fixedly arranged inside the drying box 2. The moving direction of the output end of the first linear motion component 5 is parallel to the connecting direction of the feed port 2a and the discharge port 2b. The guide frame 6 is fixedly arranged inside the drying box 2. The guide frame 6 is in the shape of a rectangular frame as a whole. The length direction of the guide frame 6 is parallel to the moving direction of the output end of the first linear motion component 5. There are two 6, and the two guide frames 6 are respectively arranged at the two ends of the feed port 2a, and the connecting line between the two guide frames 6 is parallel to the axis of the auxiliary stick 4. The clamping assembly 7 is in the shape of a rectangular frame as a whole, and the length direction of the clamping assembly 7 is parallel to the axis direction of the auxiliary stick 4. The two ends of the clamping assembly 7 are respectively arranged to be slidably arranged in the two guide frames 6, and the clamping assembly 7 includes a moving end and a fixed end. The moving end of the clamping assembly 7 is arranged above the fixed end of the clamping assembly 7, and the moving end of the clamping assembly 7 is slidably connected to the output end of the first linear moving assembly 5. The moving direction of the moving end of the clamping assembly 7 is parallel to the height direction of the drying box 2, and the first pressure sensor 8 is fixedly arranged on the output end of the first linear moving assembly 5, and the first pressure sensor 8 is arranged below the moving end of the clamping assembly 7.

[0049] The staff controls the movement of the mobile end of the clamping assembly 7 so that the mobile end of the clamping assembly 7 is away from the fixed end of the clamping assembly 7, and then the ultrafiltration membrane passes through the two auxiliary sticks 4 and moves between the mobile end of the clamping assembly 7 and the fixed end of the clamping assembly 7. At this time, the staff releases the mobile end of the clamping assembly 7, and the clamping assembly 7 completes the clamping work of the ultrafiltration membrane. Then the staff starts the first linear moving assembly 5. At this time, the pressure applied to the first pressure sensor 8 by the mobile end of the clamping assembly 7 reaches the rated value, and the first pressure sensor 8 transmits the signal to the controller. The controller controls the output end of the first linear moving assembly 5 to move from the feed port 2a of the drying box 2 to the discharge port 2b of the drying box 2, and the clamping assembly 7 drives the ultrafiltration membrane to move to the discharge port 2b. Then the staff The operator controls the moving end of the clamping assembly 7 to move away from the fixed end of the clamping assembly 7. At this time, the first pressure sensor 8 does not send a signal to the controller, and the first linear moving assembly 5 drives the clamping assembly 7 to move from the outlet 2b of the drying box 2 to the feed inlet 2a of the drying box 2. Compared with the prior art, the clamping assembly 7 and the first linear moving assembly 5 of the present application drive the ultrafiltration membrane from the feed inlet 2a of the drying box 2 to the outlet 2b of the drying box 2. The first pressure sensor 8 and the first linear moving assembly 5 cooperate to enable the clamping assembly 7 to move back and forth between the feed inlet 2a of the drying box 2 and the outlet 2b of the drying box 2, thereby avoiding the situation that the ultrafiltration membrane may not be able to accurately move to the outside of the drying box 2 after being guided into the interior of the drying box 2 by the external support roller.

[0050] See also Figures 5 to 12 As shown: the first linear motion component 5 includes a threaded rod, a driving motor 5b, a threaded block 5c and an L-shaped plate 5d, the threaded rod is rotatably arranged inside the drying box 2, the axis of the threaded rod is parallel to the connection direction of the feed port 2a and the discharge port 2b, the driving motor 5b is fixedly arranged on the drying box 2, the output shaft of the driving motor 5b is transmission-connected to the threaded rod, the threaded block 5c is threadedly connected to the threaded rod, the number of L-shaped plates 5d is two, the two L-shaped plates 5d are spaced apart on the threaded block 5c along the axis direction of the threaded rod, the first pressure sensor 8 is fixedly arranged on the threaded block 5c, the first pressure sensor 8 is arranged between the two L-shaped plates 5d, the moving end of the clamping component 7 is slidably arranged between the two L-shaped plates 5d, and the upper surface of the guide frame 6 is parallel to the upper surface of the L-shaped plate 5d.

[0051] By driving the motor 5b to rotate the threaded rod, the threaded block 5c moves linearly while the moving end of the clamping assembly 7 is always between the two L-shaped plates 5d. At this time, the clamping assembly 7 moves stably along the length direction of the guide frame 6 as a whole. Compared with the prior art, the L-shaped plate 5d and the guide frame 6 of the present application limit the moving range of the moving end of the clamping assembly 7, thereby avoiding the possibility that the moving end of the clamping assembly 7 may be disconnected from the output end of the first linear moving assembly 5 in the vertical direction, thereby causing the clamping assembly 7 to be unable to move with the output end of the first linear moving assembly 5.

[0052] See also Figures 8 to 19 As shown: a magnetic sheet 5e is provided on the upward side of the threaded block 5c, the clamping assembly 7 includes a U-shaped frame 7a, a movable plate 7b, a movable frame 7c and a first spring 7d, the two protruding ends of the U-shaped frame 7a are arranged upward along the height direction of the drying box 2, the movable plate 7b is slidably matched with the U-shaped frame 7a, the sliding direction of the movable plate 7b is parallel to the height direction of the drying box 2, the movable plate 7b is arranged above the U-shaped frame 7a, the movable frame 7c is slidably matched with the movable plate 7b, the sliding direction of the movable frame 7c is parallel to the sliding direction of the drying box 2, the movable frame 7c is arranged between the two L-shaped plates 5d, the movable frame 7c cooperates with the magnetic sheet 5e, the first spring 7d is arranged between the movable frame 7c and the movable plate 7b, and the axis of the first spring 7d is parallel to the height direction of the drying box 2.

[0053] By pressing the movable frame 7c, the movable plate 7b is driven to move downward. After the movable plate 7b contacts the ultrafiltration membrane, it slides relative to the movable frame 7c. The movable frame 7c continues to approach the first pressure sensor 8. When the movable frame 7c contacts the first pressure sensor 8, the magnetic sheet 5e fixes the position of the movable frame 7c through magnetic force. Compared with the prior art, the movable plate 7b, movable frame 7c, first spring 7d and magnetic sheet 5e of the present application cooperate so that no matter how thick the ultrafiltration membrane is, the first pressure sensor 8 can always send a stable signal, thereby avoiding the situation that when the thickness of the ultrafiltration membrane is thicker, the force transmitted to the first pressure sensor 8 by the clamping assembly 7 may not reach the rated value.

[0054] See also Figures 8 to 19 As shown: the clamping assembly 7 also includes a first limiting bolt 7e, the first limiting bolt 7e is fixedly matched with the movable plate 7b, the axis of the first limiting bolt 7e is parallel to the height direction of the drying box 2, the first limiting bolt 7e is slidably matched with the movable frame 7c, and the first spring 7d is sleeved on the first limiting bolt 7e.

[0055] The first limiting bolt 7e always maintains the connection between the movable frame 7c and the movable plate 7b when the movable frame 7c and the movable plate 7b slide relative to each other. Compared with the prior art, the first limiting bolt 7e of the present application limits the moving direction of the limiting frame, thereby avoiding the horizontal movement between the movable frame 7c and the movable plate 7b, which causes the movable frame 7c and the movable plate 7b to be disconnected.

[0056] See also Figures 8 to 19 As shown: the clamping assembly 7 also includes a guide frame 7f and a guide column 7g. The guide frame 7f is in the shape of a rectangular parallelepiped as a whole. The guide frame 7f is fixedly arranged on a side of the movable plate 7b away from the U-shaped frame 7a. The length direction of the guide frame 7f is parallel to the connecting line of the two guide frames 6. The guide column 7g is a right-angled triangular prism. The guide column 7g is fixedly arranged on the inner side wall of the drying box 2 where the discharge port 2b is opened. The inclined surface of the guide column 7g is arranged toward a position close to the top of the guide frame 7f, and the inclined surface of the guide column 7g works in conjunction with the guide frame 7f.

[0057] By moving the guide frame 7f toward the direction close to the guide column 7g, first the inclined surface of the guide column 7g will contact the guide frame 7f, and then as the first linear moving component 5 works, the guide frame 7f will move upward along the height direction of the drying box 2, so that the first pressure sensor 8 stops sending signals. Compared with the prior art, the guide frame 7f and the guide column 7g of the present application cooperate so that when the movable plate 7b moves to a position close to the discharge port 2b, the first pressure sensor 8 will automatically stop sending signals, thereby avoiding the need to manually control the movement of the movable plate 7b after the clamping component 7 is guided from the position of the feed port 2a to the position of the discharge port 2b, otherwise it will cause the clamping component 7 to conflict with the drying box 2.

[0058] See also Figures 8 to 19 As shown, the clamping assembly 7 further includes a second spring 7h, which is arranged between the movable plate 7b and the U-shaped frame 7a, and the axial direction of the second spring 7h is parallel to the height direction of the drying box 2.

[0059] The first spring 7d is arranged between the movable plate 7b and the U-shaped frame 7a, so that the initial distance between the movable frame 7c and the magnetic sheet 5e cannot cause the movable frame 7c to move. Compared with the prior art, the first spring 7d of the present application allows the movable frame 7c to be fixed in a high position, thereby avoiding the need to manually control the height of the movable plate 7b when the ultrafiltration membrane is not clamped to prevent the first pressure sensor 8 from working under force.

[0060] See also Figures 8 to 19As shown: the clamping assembly 7 also includes a second limiting bolt 7i, the second limiting bolt 7i is fixedly connected to the U-shaped frame 7a, the axis of the second limiting bolt 7i is parallel to the height direction of the drying box 2, the second limiting bolt 7i is slidably matched with the movable plate 7b, the second limiting bolt 7i is slidably matched with the guide frame 6, and the second spring 7h is sleeved on the second limiting bolt 7i.

[0061] When the clamping assembly 7 follows the movement of the output end of the first linear motion assembly 5, the second limiting bolt 7i follows it to move, thereby ensuring that the clamping assembly 7 as a whole will not undergo other forms of movement. Compared with the prior art, the second limiting bolt 7i of the present application limits the moving direction of the clamping assembly 7 as a whole, thereby avoiding the possibility that the clamping assembly 7 as a whole may be disconnected from the output end of the first linear motion assembly 5 in the horizontal direction, thereby causing the clamping assembly 7 to be unable to move together with the output end of the first linear motion assembly 5.

[0062] See also Figures 8 to 19 As shown: the clamping assembly 7 also includes a fixed strip 7j, which is arranged on the end of the movable frame 7c away from the first linear moving assembly 5, and the length direction of the fixed strip 7j is parallel to the moving direction of the output end of the first linear moving assembly 5. A fixing hole 2c is provided on the side of the drying box 2 where the feed port 2a is provided to cooperate with the fixed strip 7j.

[0063] The staff holds the fixed strip 7j outside the drying box 2 where the feed port 2a is opened, and then controls the strip to drive the movable frame 7c to move downward to complete the clamping of the ultrafiltration membrane. Compared with the prior art, the fixed strip 7j of the present application allows the staff to externally control the clamping assembly 7 to clamp the ultrafiltration membrane, thereby avoiding the situation where the clamping assembly 7 is located as a whole inside the drying box 2 and is inconvenient for the staff to operate.

[0064] See also Figures 8 to 19 As shown: it also includes a second pressure sensor 9, which is fixedly arranged on the inner side wall of the drying box 2 with a feed port 2a, and the clamping assembly 7 also includes a third spring 7k. The fixed strip 7j is slidably matched with the first limiting bolt 7e, and the sliding direction of the fixed strip 7j is parallel to the sliding direction of the first linear moving assembly 5. The fixed strip 7j is provided with a fixed block 7j1 that cooperates with the second pressure sensor 9, and the third spring 7k is arranged between the fixed strip 7j and the first limiting bolt 7e, and the axis of the third spring 7k is parallel to the moving direction of the output end of the first linear moving assembly 5.

[0065] The clamping component 7 follows the output end of the first linear moving component 5 to move in the opposite direction and approach the feed port 2a. At this time, the fixed block 7j1 contacts the second pressure sensor 9, and the second pressure sensor 9 reaches the set rated value. The second pressure sensor 9 sends a signal to the controller, and the controller controls the drive motor 5b to stop working. When the staff pushes the fixed strip 7j to move along the moving direction of the output end of the first linear moving component 5, the second pressure sensor 9 stops sending a signal. Compared with the prior art, the second pressure sensor 9 and the fixed block 7j1 of the present application cooperate so that the operation of the first linear moving component 5 can be controlled without manual operation, thereby avoiding the situation where the clamping component 7 moves to the discharge port 2b and then moves in the opposite direction to the feed port 2a and then continues to move, thereby causing the clamping component 7 to conflict with the drying box 2.

[0066] See also Figures 8 to 19 As shown: a limit strip 7c1 is provided on the movable frame 7c, the length direction of the limit strip 7c1 is parallel to the moving direction of the output end of the first linear moving component 5, and a limit groove 7j2 cooperating with the limit strip 7c1 is provided on the fixed strip 7j.

[0067] When the fixed strip 7j moves, the limit strip 7c1 always cooperates with the limit groove 7j2 to ensure that the fixed strip 7j can only move in one direction. Compared with the prior art, the limit strip 7c1 and the limit groove 7j2 of the present application cooperate to limit the moving state of the fixed strip 7j, thereby avoiding the situation that the fixed strip 7j may rotate during the sliding process, which may cause the second pressure sensor 9 to be unable to work normally under force.

[0068] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
