Description

Technical Field

[0001] The present invention relates to the technical field of filter element processing, and in particular to an error correction and diversion mechanism of an RO membrane filter element and an error correction and diversion method thereof. Background Art

[0002] As people's demands for drinking water quality increase, pure water systems are gradually becoming part of every household's drinking water system. Currently, water purifiers on the market generally utilize reverse osmosis membrane filters (also known as RO membrane filters). RO filters can filter impurities such as organic matter, colloids, bacteria, and viruses from raw water, and are particularly efficient at filtering inorganic salts, heavy metals, and other impurities. Therefore, RO filters constitute the core component of water purifiers, and the filtration performance of water purifiers is directly related to the filtration performance of the RO filter.

[0003] A common RO membrane filter element includes a central tube and a reverse osmosis membrane unit wound on the central tube, wherein the reverse osmosis membrane unit is formed by stacking several layers of cut spacers, membranes and guide cloths.

[0004] In the prior art, before rolling the film on the outer wall of the central tube, the central tube needs to be manually installed on the film rolling device. The film rolling device includes a film rolling motor, a plug connector, a tightening cylinder and an abutment column. The plug connector is fixedly connected to the output shaft of the film rolling motor, and the tightening cylinder drives the abutment column to move toward or away from the plug connector. Figure 1 As shown, one end face of the central tube 1' is flat, and the other end face has two U-shaped grooves 11'. The side wall of the plug connector has corresponding U-shaped protrusions. When the central tube is plugged into the plug connector, the protrusions must be plugged into the corresponding grooves to fully insert one end of the central tube into the plug post. In this way, when the abutment post abuts against the other end of the central tube, the reverse osmosis membrane unit can be wound in the correct position on the central tube. Otherwise, the position will be offset, resulting in defective products. However, manual loading of the central tube requires direction identification during loading, which can easily lead to fatigue and a high error rate due to long-term manual operation. As a result, there are problems of low work efficiency and time-consuming and labor-intensive work. Summary of the Invention

[0005] The present invention aims to provide a correction and diversion mechanism for an RO membrane filter element, which is highly efficient, time-saving, labor-saving, and effectively reduces the error rate. Another object of the present invention is to provide a central tube correction and diversion method for an RO membrane filter element, which is highly efficient, time-saving, and labor-saving.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: an error correction and diversion mechanism for an RO membrane filter element, comprising a frame, a silo provided on the frame, a loading device corresponding to the silo provided on the frame; a clamping device provided on the frame for movement, the clamping device clamping a central tube from the loading device;

[0007] The frame is also provided with an error correction device, which includes a material moving component and a diversion component that are connected. The central tube clamped by the material clamping device falls into the material moving component and is then transferred to the diversion component.

[0008] The diversion assembly includes an inclined diversion rack, which includes a central tube unloading channel and a finished product unloading channel. The central tube unloading channel is connected to the material transfer assembly, and the finished product unloading channel is relatively located downstream of the central tube unloading channel. A lower tube hole located in the central tube unloading channel is opened on the diversion rack, and the central tube unloading channel and the finished product unloading channel are separated by a vertical baffle set by a lifting arrangement, and the lower tube hole is movable with an inclined baffle.

[0009] By adopting the above technical solution, the center tube is placed in the material bin, the loading device takes out a center tube from the material bin, and then clamps the center tube through the clamping device. If the clamping device can completely clamp the center tube, the clamping device can move the center tube to the film rolling process for film rolling. After the film rolling is completed, a filter element is formed, and the clamping device moves the filter element to the top of the moving assembly, and the filter element falls onto the moving assembly and is sent to the diversion rack through the moving assembly. At this time, the vertical baffle moves vertically downward, so that the center tube unloading channel is connected with the finished product unloading channel, and the filter element can be rolled to the finished product unloading channel through the center tube unloading channel and successfully unloaded; if the clamping device cannot completely clamp the center tube, the clamping device moves the center tube directly to the moving assembly and is sent to the diversion rack through the moving assembly. At this time, the inclined baffle moves in the direction away from the lower tube hole, so that the center tube can fall directly from the lower tube hole when it is pushed into the center tube unloading channel. In this way, during the loading and unloading process, when the center tube is reversely clamped on the clamping device, the center tube and the finished product can be diverted through the diverter rack, realizing a better automatic error correction function, which is efficient, saves time and labor, and effectively reduces the error rate.

[0010] The present invention is further configured as follows: the material moving assembly includes a rodless cylinder, a pushing block installed on the rodless cylinder, and a material receiving rack. The rodless cylinder is fixedly installed on the frame through the mounting rack. The rodless cylinder drives the objects falling on the material receiving rack to move toward the diversion assembly through the pushing block.

[0011] By adopting the above technical solution, when the central tube or filter element falls onto the receiving rack, the rodless cylinder is started, and the central tube or filter element can be pushed onto the diversion rack for diversion through the pushing block.

[0012] The present invention is further configured as follows: an infrared sensing device is provided on the mounting frame, and the infrared sensing device is correspondingly irradiated on the material receiving channel of the material receiving frame.

[0013] By adopting the above technical solution, when the central tube or filter element falls onto the receiving rack, the infrared sensing device senses the object on the receiving rack and drives the rodless cylinder to push the push block to move, thereby achieving precise control.

[0014] The present invention is further configured as follows: the vertical baffle is lifted and set in the lower tube hole by a lifting cylinder, and the inclined baffle is avoided in the lower tube hole by an oblique push cylinder. When the vertical baffle descends and is located below the diverter rack, the central tube unloading channel is connected to the finished product unloading channel, and the finished product is unloaded; when the inclined baffle avoids the lower tube hole, the central tube is unloaded through the lower tube hole.

[0015] The present invention is further configured as follows: the bottom surface of the silo is configured as an inclined surface, a through hole is provided at the lowest point of the inclined surface, the loading device includes a first lifting assembly and a second lifting assembly, the first lifting assembly includes a lifting block and a first lifting cylinder for driving the lifting block, and the lifting block is lifted and lowered in the through hole; the second lifting assembly includes a storage rack and a second lifting cylinder for driving the storage rack; the first lifting assembly pushes the center pipe from the silo to the storage rack.

[0016] By adopting the above technical solution, when several center tubes are stored in the silo, they roll along the inclined surface in the direction of the through hole. When the first lifting cylinder is lifted, the lifting block is lifted upward, and the center tube located at the through hole position can be pushed out upward, so that it rolls to the storage rack adjacent to it. When the clamping device moves to above the storage rack, the second lifting cylinder drives the storage rack to rise, so that the clamping device can be clamped at both ends of the center tube. In this way, the feeding of the center tube is more orderly.

[0017] The present invention is further configured as follows: a movable frame is provided on the frame through sliding movement of a displacement electric cylinder, the clamping device includes a plug-in column, an abutment column, and a tightening cylinder arranged on the movable frame, the plug-in column and the abutment column are coaxially arranged, a U-shaped protrusion is provided on the outer wall of the plug-in column, and the tightening cylinder drives the abutment column to move closer to or away from the plug-in column; a driving motor is provided on the movable frame, and the plug-in column is fixedly connected to the output shaft of the driving motor.

[0018] By adopting the above technical solution, when the clamping device is clamped on the center tube, the second lifting assembly lifts the center tube so that the center tube is coaxial with the center axis of the plug-in column, and then the abutting cylinder drives the abutting column to push the center tube axially, so that the plug-in column is correspondingly plugged into one end of the center tube. During the plug-in process, the driving motor can drive the plug-in column to rotate so that the protrusion can be inserted into the groove accordingly.

[0019] The present invention is further configured as follows: a pushing assembly is also provided on the movable frame, the pushing assembly includes a pushing cylinder and a pushing block, the pushing block is fixedly connected to the piston rod of the pushing cylinder, a through hole is provided on the pushing block, the pushing block is movable relative to the plug-in column through the through hole, and the aperture of the through hole is larger than the outer diameter of the plug-in column and smaller than the outer diameter of the center tube.

[0020] By adopting the above technical solution, when the center tube or filter element is removed from the clamping device, the pushing cylinder is started, driving the pushing block to move along the plug-in column. The pushing block pushes the end face of the center tube or filter element, and the center tube or filter element can be pushed away from the plug-in column. The pushing block is moved by inserting it through the through hole outside the plug-in column, so that the operation during the pushing process is more stable, the force distribution on the end face of the center tube or filter element is more balanced, and when the center tube or filter element falls, it can accurately fall into the receiving rack.

[0021] The present invention is further configured as follows: a film pasting device is also provided on the frame, the film pasting device includes a lifting platform, a lifting electric cylinder for driving the lifting platform to lift, a material axis and a cutting component provided on the lifting platform; a gluing plane is provided on the lifting platform, a pressing rod is provided on the gluing plane, the central axis of the pressing rod is parallel to the material axis, and a number of convex rings are provided at equal intervals on the side walls of the pressing rod.

[0022] By adopting the above technical solution, the blue adhesive sheet roll is mounted on the material shaft. The front end of the blue adhesive sheet roll is pulled onto the adhesive application surface, with the sticky side facing upward. The pressing rod presses against the blue adhesive sheet. Once the film is rolled onto the outer wall of the central tube, the movable frame moves the rolled central tube above the adhesive application surface. The lifting cylinder drives the lifting platform upward, causing the sticky side of the blue adhesive to adhere to the outer wall of the reverse osmosis membrane unit. Since the pressing rod presses against the blue adhesive sheet, it can press the sheet and prevent it from slipping. In addition, a number of raised rings are provided on the outer wall of the pressing rod. These rings create a gap between the outer wall of the pressing rod and the blue adhesive sheet, preventing the blue adhesive sheet from completely adhering to the pressing rod and being difficult to pull out.

[0023] The present invention is further configured as follows: a roller is rotatably provided on the lifting platform, the roller is provided at the feed end of the glue-laminating plane, the central axis of the roller is parallel to the pressing rod, and the side wall of the roller protrudes from the glue-laminating plane.

[0024] By adopting the above technical solution, the rotating roller serves as a feeding guide for the blue adhesive sheet. Since the highest point of the rotating roller is higher than the gluing plane, and the adhesive platform is equipped with a pressing rod to press the blue adhesive sheet, when the blue adhesive sheet extends from the rotating roller to the adhesive platform, the blue adhesive sheet on the adhesive platform is generally V-shaped, and the front end of the blue adhesive sheet is relatively upward, which facilitates its adhesion to the outer wall of the reverse osmosis membrane unit.

[0025] Another technical purpose of the present invention is achieved through the following technical solution: a central tube error correction and diversion method of an RO membrane filter element, comprising the following steps:

[0026] S1. Loading: The loading device pushes the central tube out of the silo for loading;

[0027] S2. Clamping: The clamping device moves to the top of the loading device and clamps the ejected center tube from the loading device;

[0028] S3, transfer: when the plug-in column of the clamping device is inserted into the central tube, the clamping device moves the central tube to the film rolling device for film rolling; when the plug-in column of the clamping device cannot be inserted into the central tube, the clamping device moves the central tube to the error correction device;

[0029] S4. Center tube unloading: The clamping device places the center tube on the material transfer assembly. The program controls the movement of the inclined baffle, which moves away from the tube unloading hole to avoid it. The vertical baffle remains between the center tube unloading channel and the finished product unloading channel. When the material transfer assembly pushes the center tube into the center tube unloading channel, the center tube is unloaded from the tube unloading hole under its own gravity.

[0030] S5. Finished product unloading: The clamping device moves the finished product of the film roll to the material transfer assembly. The program controls the vertical baffle to descend, and the inclined baffle is still blocking the lower tube hole. The material transfer assembly pushes the finished product to the diversion rack. The finished product passes through the central tube unloading channel and rolls out from the finished product unloading channel.

[0031] By adopting the above technical solution, the central tube and the finished filter element are automatically diverted by using a diverter frame, which has the effects of high efficiency, time saving and labor saving, and is not prone to errors.

[0032] In summary, the present invention has the following beneficial effects:

[0033] 1. The error correction and separation component is used to divert the center tube and the finished filter element during the unloading process. During the unloading and unloading process, when the center tube is clamped on the clamping device in the opposite direction, the diversion frame can divert the center tube and the finished filter element, realizing a better automatic error correction function, which is efficient, time-saving and labor-saving, and effectively reduces the error rate.

[0034] 2. The push block is inserted into the outside of the plug-in column through the through hole, which makes the operation more stable during the pushing process, and the force distribution on the end face of the center tube or filter element is more balanced. When the center tube or filter element falls, it can fall accurately into the receiving rack;

[0035] 3. The blue adhesive sheet on the adhesive platform is V-shaped as a whole by cooperating with the roller and the pressing rod. The front end of the blue adhesive sheet is relatively upward, which is convenient for it to be adhered to the outer wall of the reverse osmosis membrane unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The present invention will be further described below with reference to the accompanying drawings.

[0046] An error correction and diversion mechanism for an RO membrane filter element and an error correction and diversion method thereof, such as Figure 2-4As shown, it includes a frame 1, a silo 11 is provided on the frame 1, the bottom surface of the silo 11 is set as an inclined surface, and a strip-shaped through-hole 111 is opened at the lowest point of the inclined surface. A feeding device 2 corresponding to the through-hole 111 is provided on the frame 1, and the feeding device 2 includes a first lifting assembly and a second lifting assembly. The first lifting assembly includes a lifting block 21 and a first lifting cylinder 22 that drives the lifting block 21. The first lifting cylinder 22 is fixedly connected to the frame 1 vertically upward, and the first lifting cylinder 22 drives the lifting block 21 to move up and down in the through-hole 111; the second lifting assembly includes a storage The storage rack 23 is mounted on a support frame 1 and a second lifting cylinder 24 is provided to drive the storage rack 23. The second lifting cylinder 24 is fixedly connected to the frame 1, and the storage rack 23 is fixedly arranged on the piston rod of the second lifting cylinder 24. The side wall of the discharge end of the silo 11 is provided with an inclined guide surface 112. When the lifting block 21 is in a raised state and the storage rack 23 is in an initial state, the upper surface of the lifting block 21, the inclined guide surface 112 and the storage rack 23 are adjacent to each other. Since the inclined guide surface 112 is relatively inclined toward the storage rack 23, and the top surface of the lifting block 21 is also relatively inclined, the central tube 1' can automatically roll from the first lifting assembly to the storage rack 23.

[0047] When several center tubes are stored in the silo 11, they roll along the inclined surface toward the through hole 111. When the first lifting cylinder 22 is lifted, the lifting block 21 is lifted upward, and the center tube located at the through hole 111 is pushed out upward, so that it rolls to the adjacent storage rack 23 through the inclined guide surface 112. In this way, the loading of the center tubes is more orderly.

[0048] like Figure 5 As shown, a clamping device is movably provided on the frame 1, and the clamping device clamps the central tube from the loading device 2; a movable frame 3 is slidably provided on the frame 1 through a displacement electric cylinder 12, and the clamping device includes a plug-in column 31, an abutting column 32, and a tightening cylinder 33 provided on the movable frame 3, the plug-in column 31 and the abutting column 32 are coaxially arranged, and a U-shaped protrusion 311 is provided on the outer wall of the plug-in column 31, and the tightening cylinder 33 drives the abutting column 32 to move close to or away from the plug-in column 31; a driving motor 34 is provided on the movable frame 3, and the plug-in column 31 is fixedly connected to the output shaft of the driving motor 34. A pushing assembly is also provided on the mobile frame 3, which includes a pushing cylinder 35 and a pushing block 36. The pushing block 36 is fixedly connected to the piston rod of the pushing cylinder 35. A through hole is provided on the pushing block 36. The pushing block 36 is moved relative to the plug-in column 31 through the through hole. The aperture of the through hole is larger than the outer diameter of the plug-in column 31 and smaller than the outer diameter of the center tube.

[0049] When the clamping device moves to the top of the storage rack 23, the second lifting cylinder 24 drives the storage rack 23 to rise and lift the center tube, so that the center tube is coaxial with the central axis of the plug-in column 31. Then, the clamping cylinder 33 drives the abutting column 32 to push the center tube axially, so that the plug-in column 31 is correspondingly plugged into one end of the center tube and the abutting column 32 is abutted against the other end of the center tube. During the plugging process, the drive motor 34 can drive the plug-in column 31 to rotate so that the protrusion 311 is correspondingly inserted into the groove 11'. When the center tube or filter element is removed from the clamping device, the pushing cylinder 35 is activated, driving the push block 36 to move along the plug-in column 31. The push block 36 pushes against the end face of the center tube or filter element, thereby pushing the center tube or filter element away from the plug-in column 31. The push block 36 is inserted into the outside of the plug-in column 31 through the through hole, which makes the operation more stable during the pushing process and the force distribution on the end face of the center tube or filter element more balanced.

[0050] like Figure 6 As shown, the frame 1 is also provided with a film pasting device 4, which includes a lifting platform 41, a lifting electric cylinder 42 that drives the lifting platform 41 to rise and fall, a material shaft 43 provided on the lifting platform 41, and a cutting assembly. The cutting assembly includes a cutter 45 and a cutting cylinder 46 that drives the cutter 45 to move. The lifting platform 41 is provided with a gluing plane 411, and a pressing rod 47 is provided on the gluing plane 411. The central axis of the pressing rod 47 is parallel to the material shaft 43, and a plurality of convex rings 471 are evenly spaced on the side wall of the pressing rod 47. A rotating roller 48 is provided on the lifting platform 41. The rotating roller 48 is provided at the feed end of the gluing plane. The central axis of the rotating roller 48 is parallel to the pressing rod 47, and the upper side wall of the rotating roller 48 protrudes from the gluing plane. The cutting assembly is provided at the discharge end of the gluing plane.

[0051] The blue adhesive sheet roll 44 is installed on the material shaft 43, and the front end of the blue adhesive sheet roll 44 is pulled to the adhesive surface 411, with the sticky side facing up, and the pressing rod 47 is pressed on the blue adhesive sheet. After the outer wall of the central tube is rolled up, the mobile frame 3 moves the central tube of the rolled film to above the adhesive surface 411, and the lifting electric cylinder 42 drives the lifting platform 41 to rise. Under the action of the driving motor 34, the filter element is driven to rotate, so that the sticky side of the blue adhesive is adhered to the outer wall of the reverse osmosis membrane unit. Subsequently, the cutting cylinder 46 drives the cutter 45 to move to cut the blue adhesive. The film roll 44 is cut; a rotating roller 48 guides the blue adhesive sheet. Because the highest point of the rotating roller 48 is above the adhesive application surface, and a pressure rod 47 is provided on the adhesive platform to press against the blue adhesive sheet, when the blue adhesive sheet extends from the rotating roller 48 to the adhesive platform, the blue adhesive sheet on the adhesive platform forms a V-shape, with the front end of the blue adhesive sheet relatively tilted upward, facilitating its adhesion to the outer wall of the reverse osmosis membrane unit. Furthermore, the pressure rod 47 on the blue adhesive sheet also acts as a pressure force to prevent it from slipping. Furthermore, a plurality of raised rings 471 are provided on the outer wall of the pressure rod 47. These rings create a gap between the outer wall of the pressure rod 47 and the blue adhesive sheet, preventing the blue adhesive sheet from completely adhering to the pressure rod 47 and being difficult to pull out. Since the movable frame 3 is also provided with a top core assembly, the top core assembly includes a top roller, which is matched with the outer wall of the filter element after the film is rolled, the excess blue adhesive sheet after cutting can be pressed and adhered to the outer wall of the filter element.

[0052] like Figure 7-8 As shown, the frame 1 is also provided with an error correction device, which includes a connected material moving component 5 and a diversion component 6. The central tube clamped by the material clamping device falls into the material moving component 5 and is then transferred to the diversion component 6. The material moving component 5 includes a rodless cylinder 511, a pushing block 52 installed on the rodless cylinder 511, and a material receiving rack 53. The rodless cylinder 511 is fixedly mounted on the frame 1 through the mounting frame 51. The rodless cylinder 511 drives the objects falling on the material receiving rack 53 to move toward the diversion component 6 through the pushing block 52. An infrared sensing device 512 is provided on the mounting frame 51. The infrared sensing device 512 is electrically connected to the rodless cylinder 511. The infrared sensing device 512 is located at one end of the material receiving rack 53 away from the diversion component 6, and corresponds to the material receiving channel of the material receiving rack 53. The frame 1 is provided with a jacking cylinder 13, and the material receiving rack 53 is fixedly provided on the piston rod of the jacking cylinder 13. The upper surface of the material receiving rack 53 is provided with a V-shaped groove 531, which is convenient for receiving the central tube or the finished filter element to prevent rolling.

[0053] like Figure 7-8As shown, the diverter assembly 6 includes an inclined diverter frame 61, which includes a central tube unloading channel 611 and a finished product unloading channel 612. The central tube unloading channel 611 is connected to the receiving frame 53. When the top force cylinder 13 lifts the receiving frame 53, the receiving frame 53 and the central tube unloading channel 611 are in the same straight line, and the finished product unloading channel 612 is relatively located downstream of the central tube unloading channel; a lower pipe hole 62 is opened on the diverter frame 61 and is located in the central tube unloading channel 611. The lower pipe hole 62 can be used for the central tube to pass through. The central tube unloading channel 611 and the finished product unloading channel 612 are connected. The two parts are separated by a vertical baffle 63 that is lifted and lowered vertically by a lifting cylinder 64 and set in the lower tube hole 62. The lower tube hole 62 is provided with an inclined baffle 65, and the inclined angle of the inclined baffle 65 is the same as that of the diverter rack 61. The inclined baffle 65 is set to avoid the lower tube hole 62 by an inclined push cylinder 66. When the vertical baffle 63 is lowered and positioned below the diverter rack 61, the central tube discharge channel 611 is connected to the finished product discharge channel 612, and the finished filter element is discharged. When the inclined baffle 65 avoids the lower tube hole 62, the central tube is discharged through the lower tube hole 62. A filter element receiving bin 14 and a central tube receiving bin 15 are placed below the frame 1. The filter element receiving bin 14 is correspondingly located below the finished product discharge channel 612, and the central tube receiving bin 15 is correspondingly located below the lower tube hole 62. The side wall of the vertical baffle 63 is also provided with a material guide plate 631, which is located below the lower tube hole 62. When the central tube falls from the lower tube hole 62, it falls into the central tube receiving bin 15 under the guidance of the material guide plate 631, which can prevent the central tube from colliding with the lifting cylinder 64 during the falling process and causing damage to a certain extent.

[0054] The error correction and diversion method comprises the following steps:

[0055] S1, loading: the loading device 2 pushes the central tube out of the silo 11 for loading;

[0056] S2, clamping: the clamping device moves to the top of the loading device 2 and clamps the ejected center tube from the loading device 2;

[0057] S3, transfer: when the plug-in column 31 of the clamping device is inserted into the central tube, the clamping device moves the central tube to the film rolling device for film rolling. When the plug-in column 31 of the clamping device cannot be inserted into the central tube, the clamping device moves the central tube to the error correction device;

[0058] S4. Center tube unloading: The clamping device places the center tube on the material transfer assembly 5. The program controls the movement of the inclined baffle 65, which moves away from the tube lowering hole 62 to avoid it. The vertical baffle 63 remains between the center tube unloading channel 611 and the finished product unloading channel 612. When the material transfer assembly 5 pushes the center tube into the center tube unloading channel 611, the center tube is unloaded from the tube lowering hole 62 under its own weight.

[0059] S5, finished product unloading: The clamping device moves the finished product of the film roll to the material transfer assembly 5. The program controls the vertical baffle 63 to descend, and the inclined baffle 65 is still blocked at the lower tube hole 62. The material transfer assembly 5 pushes the finished product to the diversion rack 61. The finished product passes through the central tube unloading channel 611 and rolls out from the finished product unloading channel 612.

[0060] Among them, in S3, after the film rolling is completed, the filter element can be moved to the film pasting device 4, and the blue film can be pasted on the outer wall of the filter element.

[0061] The basic working principle of the present invention is as follows: the central tube is placed in the hopper 11, the loading device 2 pushes a central tube out of the hopper 11 and rolls it onto the storage rack 23, and then the central tube is clamped by the clamping device. If the plug-in column 31 of the clamping device can be fully plugged into one end of the central tube, the clamping device can transfer the central tube to the film rolling process for film rolling. After the film rolling is completed, the clamping device transfers the filter element to the film pasting device 4 for film pasting, and then moves to the top of the material transfer component 5. The pushing component pushes the filter element away from the plug-in column 31, and the filter element falls accurately onto the receiving rack 53. When the infrared sensing device 512 detects the object on the receiving rack 53, the rodless air filter is automatically released. When the cylinder 511 is started, the pushing block 52 can push the filter element onto the diverter rack 61. At this time, the lifting cylinder 64 drives the vertical baffle 63 to move downward, so that the central tube discharge channel 611 is connected to the finished product discharge channel, and the filter element can be rolled to the finished product discharge channel through the central tube discharge channel 611 and successfully discharged. If the clamping device cannot completely clamp the central tube, due to program memory, the program controls the clamping device to move the central tube directly to the receiving rack 53 and then to the diverter rack 61. At this time, the inclined baffle 65 moves upward in a direction away from the lower tube hole 62, so that when the central tube is pushed into the central tube discharge channel 611, it can fall directly from the lower tube hole 62. In this way, during the loading and unloading process, when the central tube is reversely clamped on the clamping device, the diverter rack 61 can divert the central tube and the finished product, realizing a better automatic error correction function, which is efficient, time-saving, labor-saving, and effectively reduces the error rate.

[0062] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
