Description

Technical Field

[0001] This invention relates to the field of spinning paper tube drying equipment, and more particularly to a dryer for spinning paper tubes. Background Technology

[0002] Textile paper tubes are hollow cylindrical or conical paper products, typically made from multiple layers of cardboard or paper rolled together. They are widely used in textiles, plastic films, metal foils, paper, wires and cables, building materials, pharmaceuticals, food, and other industries. During the production of spinning paper tubes, drying and shaping are required, necessitating the use of a dryer.

[0003] In existing dryers, during the drying process of spinning paper tubes, because the spinning paper tubes are made of paper and lack internal support, the spinning paper tubes may shrink and change shape due to the drying process. Furthermore, there is no external force to resist and shape the spinning paper tubes. Therefore, the final dried spinning paper tubes do not meet the actual requirements, affecting the overall product quality. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a dryer for spinning paper tubes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Multiple first conveyor belts are installed on the top of the inner wall of the first support. A drying box is connected to the top of the second support. Multiple second conveyor belts are installed at the bottom of the second support below the drying box.

[0008] Preferably, a plurality of third conveyor belts are installed at the bottom of the inner side of the second bracket. The third conveyor belts are close to one end of the outer wall of the second mounting plate. A second partition is installed between two adjacent third conveyor belts, and a support rod is installed between two adjacent second partitions.

[0009] Preferably, the top of the second bracket has a baffle that can move vertically and is slidably installed along the width direction. Both ends of the top of the second bracket have a first groove along the width direction. A first electric slider is slidably installed inside the first groove. The bottom of the first electric slider is connected to the top of the baffle through a first electric telescopic rod.

[0010] Preferably, the bottom of the baffle is provided with multiple protrusions, which can be inserted between two second partitions and block the corresponding third conveyor belt. Multiple air holes are also provided at the bottom of the protrusions. A bellows with a suction function is installed on the top of the second support. The bellows is connected to the air holes through a hose. Multiple cameras are installed on one outer wall of the baffle.

[0011] Preferably, the top of the first mounting plate has a plurality of first through holes, and the top of the second mounting plate has a plurality of second through holes. The size of the first through holes and the second through holes are adapted to the size of the fixing cone, and the fixing cone can be inserted into the interior of the first through holes and the second through holes. A wiping cotton is also installed on the inner side wall of the first through hole.

[0012] Preferably, two fourth electric telescopic rods are connected between the bottom of the first mounting plate and the inner bottom of the second bracket, and two third electric telescopic rods are connected between the bottom of the second mounting plate and the inner bottom of the second bracket. The tops of the two third electric telescopic rods are hinged to the two ends of the outer wall of the second mounting plate through U-shaped hinge seats.

[0013] Preferably, a second connecting plate is installed on both sides of one end of the outer wall of the second support between the baffle and the second conveyor belt. Two clamping pieces that can move vertically are slidably installed on the bottom of the second connecting plate. A second sliding groove is opened along the length direction at the bottom of the second connecting plate. Two second electric sliders are slidably installed inside the second sliding groove. The bottom of the second electric sliders is connected to the top of the clamping pieces.

[0014] Preferably, a fifth electric telescopic rod is installed on both sides of one end of the outer wall of the second bracket between the baffle and the second conveyor belt. The extended end of the fifth electric telescopic rod is connected to a first connecting block. A sixth electric telescopic rod is connected between one side of the outer wall of the first connecting block and one end of the second connecting plate. A first electric rotating rod is connected between the fifth electric telescopic rod and the first connecting block. A second electric rotating rod is also connected between the sixth electric telescopic rod and the second connecting plate. A seventh electric telescopic rod is connected between the clamp and the second electric slider.

[0015] Preferably, a first partition is installed between two adjacent first conveyor belts, and an electric heating plate is installed on the inner side wall of the first bracket below each first conveyor belt. Multiple mounting slots are opened on the outer bottom of the fixed cone, and an eighth electric telescopic rod is connected inside the mounting slot. The other end of the eighth electric telescopic rod is connected to an electric push bar.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, by setting a fixed cone and a second through hole, the second through hole can wrap the spinning paper tube from the outside. During the drying process, the fixed cone can provide resistance and support to the inside of the spinning paper tube. The two work together to prevent the spinning paper tube from deforming during the drying process and affecting the product quality.

[0018] 2. In this invention, by setting a second electric telescopic rod and a first through hole, since the spinning paper tube has been preheated by the heating plate, if the spinning paper tube is adhered to the fixed cone, the adhesion will not be particularly tight. Then, by retracting the second electric telescopic rod, the spinning paper tube can be detached from the outside of the fixed cone. At the same time, due to the action of the second electric telescopic rod, the fixed cone can also be accurately inserted and fixed to the spinning paper tube. The wiping cotton inside the first through hole can clean the outside of the fixed cone to ensure the cleanliness of the fixed cone and prevent the solidified glue from affecting the subsequent support and fixation of the fixed cone for other spinning paper tubes.

[0019] 3. In this invention, a baffle is installed, and the baffle extends downward via a first electric telescopic rod, causing the protrusion at the bottom of the baffle to insert into the top end of the third conveyor belt and block it. Despite the blockage, the third conveyor belt continues to operate normally, allowing the dried spinning paper tubes to be stacked horizontally for convenient subsequent transport. When the number of spinning paper tubes stacked reaches a preset quantity, the corresponding first electric telescopic rod is retracted to output the stacked spinning paper tubes, which can then be collected and stacked using external equipment or manually. Furthermore, when the baffle retracts upward, the air box can be activated, and the air holes at the bottom of the baffle can absorb and clean paper scraps generated on the outside of the spinning paper tubes due to drying or friction, maintaining the aesthetic appearance of the spinning paper tubes and preventing paper scraps from affecting product quality.

[0040] As a technical optimization of the present invention, the top of the first mounting plate 8 is provided with a plurality of first through holes 20, and the top of the second mounting plate 9 is provided with a plurality of second through holes 21. The dimensions of the first through holes 20 and the second through holes 21 are adapted to the fixing cone 19, and the fixing cone 19 can be inserted into the interior of the first through holes 20 and the second through holes 21. The inner sidewall of the first through hole 20 is also provided with wiping cotton.

[0041] As a technical optimization of the present invention, two fourth electric telescopic rods 23 are connected between the bottom of the first mounting plate 8 and the inner bottom of the second bracket 5, and two third electric telescopic rods 22 are connected between the bottom of the second mounting plate 9 and the inner bottom of the second bracket 5.

The second mounting plate 9 is rotatably connected to the U-shaped hinge seat through a third electric rotating rod.

[0042] As a technical optimization of the present invention, a second connecting plate 24 is also installed on both sides of one end of the outer wall of the second support 5 between the baffle 12 and the second conveyor belt 7. Two clamping pieces 30 that can move in the vertical direction are slidably installed on the bottom of the second connecting plate 24. A second sliding groove 28 is opened on the bottom of the second connecting plate 24 along the length direction. Two second electric sliders 29 are slidably installed inside the second sliding groove 28. The bottom of the second electric sliders 29 is connected to the top of the clamping pieces 30.

[0043] As a technical optimization of the present invention, a fifth electric telescopic rod 25 is installed on both sides of one end of the outer wall of the second support 5 between the baffle 12 and the second conveyor belt 7. The extended end of the fifth electric telescopic rod 25 is connected to a first connecting block 26. A sixth electric telescopic rod 27 is connected between one side of the outer wall of the first connecting block 26 and one end of the second connecting plate 24. A first electric rotating rod 31 is connected between the fifth electric telescopic rod 25 and the first connecting block 26. A second electric rotating rod 32 is also connected between the sixth electric telescopic rod 27 and the second connecting plate 24. A seventh electric telescopic rod is connected between the clamp 30 and the second electric slider 29.

[0044] As a technical optimization of the present invention, a first partition 3 is also installed between two adjacent first conveyor belts 4, and an electric heating plate 2 is installed on the inner side wall of the first bracket 1 below each first conveyor belt 4. Multiple mounting slots are opened on the outer bottom of the fixed cone 19, and an eighth electric telescopic rod is connected inside the mounting slot. The other end of the eighth electric telescopic rod is connected to the electric push bar.

[0045] When using this invention, the entire device is placed in a predetermined position and powered on, and the entire device can then be used normally. It should be noted that the conical spinning paper tubes can be transported to the top surface of each first conveyor belt 4 through a preset production line. Due to the guiding effect of the first partition 3 between the two first conveyor belts 4, the spinning paper tubes can be arranged in an orderly manner and transported to the next stage for drying during the transportation of the spinning paper tubes by the first conveyor belts 4. At the same time, during the transportation of the spinning paper tubes by the first conveyor belts 4, the heating plate 2 is activated. After the heating plate 2 is activated, it can increase the surface temperature of the first conveyor belts 4, which can preliminarily heat and solidify the glue inside the spinning paper tubes during the transportation process, preventing the glue from not solidifying and affecting normal operation during the subsequent drying process.

[0046] It should be noted that in the production process of the spinning paper tube in the existing technology, since the spinning paper tube is made by gluing and winding the cut paper, the glue itself may not be completely solidified during the drying process. Therefore, in order to ensure the normal operation of subsequent work, the spinning paper tube is preheated.

[0047] When the drying process begins, the second conveyor belt 7 and the third conveyor belt 11 are started simultaneously. After starting, the second conveyor belt 7 can rotate counterclockwise. Because multiple fixed cones 19 are installed on the outer wall of the second conveyor belt 7 along the circumferential direction, when the fixed cone at the bottom of the second conveyor belt 7 rotates and faces the discharge end of the first conveyor belt 4 in the horizontal direction, the second electric telescopic rod 18 extends outward, allowing the corresponding fixed cone 19 to move in the horizontal direction. Since the size of the fixed cone 19 is compatible with the spinning paper tube, the fixed cone 19 can be inserted into the spinning paper tube for fixation. The remaining fixed cones 19 can be inserted and fixed to the spinning paper tube transported at the top of the first conveyor belt 4 using the same operation. Due to the setting of the second electric telescopic rod 18, the spinning paper tube will not fall off the connection between the first conveyor belt 4 and the second conveyor belt 7. In addition, the rotation speed of the first conveyor belt 4 and the second conveyor belt 7 can be controlled by a preset control system, so that the fixed cone 19 can be inserted into the spinning paper tube; the position of the spinning paper tube can also be adjusted manually or by an external robotic arm to ensure that the fixed cone 19 is accurately inserted into the spinning paper tube.

[0048] During the startup of the first conveyor belt 4 and the second conveyor belt 7, the drying chamber 33 is started simultaneously, allowing the drying chamber 33 to dry the spinning paper tube fixed by the solid cone 19. After the spinning paper tube is fixed by the fixing cone 19, it is transported from one end of the second conveyor belt 7 to the other end, thus completing the drying process. When the dried spinning paper tube is transported to the bottom of the second conveyor belt 7, it will not fall off due to gravity because the electric pusher is in contact with and fixes the spinning paper tube. Since the spinning paper tube is conical, when it is located on the top surface of the first conveyor belt 4, its bottom opening is tilted and not on the same horizontal line as the fixing cone 19. During the feeding process of the fixing cone 19 inserting into the spinning paper tube, the electric pusher is designed to extend outward adaptively after the fixing cone 19 is inserted into the spinning paper tube, so that the fixing cone 19 can fix and straighten the spinning paper tube after insertion, reducing errors in the working process and ensuring work efficiency.

[0049] When the number of spinning paper tubes corresponding to the second through hole 21 at the top of the second mounting plate 9 are transported to the top of the second mounting plate 9, the third electric telescopic rod 22 extends outward so that the second mounting plate 9 can wrap around the spinning paper tubes outside the corresponding fixing cone 19. Since the size of the second through hole 21 is adapted to the spinning paper tube, the second through hole 21 can wrap the spinning paper tube from the outside. In addition, during the drying process, the fixing cone 19 can provide internal resistance support for the spinning paper tube. The two work together to prevent the spinning paper tube from deforming during the drying process and affecting the product quality.

[0050] After the spinning paper tube is located inside the second through hole 21 and has been dried in the drying oven 33, if some glue has solidified and there is still adhesion between the spinning paper tube and the fixed cone 19, the fixed cone 19 can be reciprocated by the corresponding second electric telescopic rod 18, so that the spinning paper tube can be forcefully dropped into the second through hole 21. It should be noted that since the spinning paper tube has been preheated by the electric heating plate 2, if the spinning paper tube is stuck to the fixed cone 19, the adhesion will not be particularly tight. Then, the second electric telescopic rod 18 can be retracted to remove the spinning paper tube from the outside of the fixed cone 19.

[0051] When all the second through holes 21 at the top of the second mounting plate 9 are filled with spinning paper tubes, the height of the second mounting plate 9 can be adjusted adaptively by the third electric telescopic rod 22. The adjustment is stopped when the second mounting plate 9 is adjusted to the height at which it can rotate. Then, the second mounting plate 9 is rotated toward the baffle 12 by the corresponding third electric rotating rod until the spinning paper tube can fall out of the second through hole 21. The spinning paper tube at the top of the second mounting plate 9 located inside the second through hole 21 can fall to the top surface of the third conveyor belt 11 under the action of gravity. Since the third conveyor belt 11 has started to run, and the bottom of the spinning paper tube is facing the top of the third conveyor belt 11, the spinning paper tube will always be positioned with its small end facing the second conveyor belt 7 due to the resistance of the support rod 34 during the fall under gravity. The above operation can be repeated to continuously transport the spinning paper tube to the top surface of the third conveyor belt 11.

[0052] When the spinning paper tube falls onto the top surface of the third conveyor belt 11, the baffle 12 extends downward via the first electric telescopic rod 17, causing the protrusion at the bottom of the baffle 12 to insert into one end of the top of the third conveyor belt 11 and block it. Despite this blockage, the third conveyor belt 11 continues to operate normally, allowing the dried spinning paper tubes to be stacked horizontally for easy transport. When the number of spinning paper tubes stacked reaches a preset quantity, the corresponding first electric telescopic rod 17 is retracted to output the stacked tubes, which can then be collected and stacked manually or via external equipment. Furthermore, when the baffle 12 retracts upward, the air box 6 can be activated, and the air holes 14 at the bottom of the baffle 12 can absorb and clean the paper scraps generated on the outside of the spinning paper tubes due to drying or friction, maintaining the tubes' appearance and preventing paper scraps from affecting product quality. Simultaneously, the baffle 12 can slide inside the second bracket 5 via the first electric slider 16, allowing the air holes 14 at the bottom of the baffle 12 to have a wider cleaning area.

[0053] During the process of the baffle 12 blocking the third conveyor belt 11, the camera 13 can capture images of the spinning paper tubes located on the top surface of the third conveyor belt 11. The captured images are then compared with preset qualified spinning paper tube images through the background control system to detect whether the quality of the spinning paper tubes is qualified. This prevents the stacking process from being affected by one unqualified spinning paper tube, which would result in unqualified spinning paper tube products after stacking and require re-stacking. If an unqualified spinning paper tube is detected, the position of the two clamping plates 30 can be adjusted horizontally using the sixth electric telescopic rod 27, and the clamping plates 30 can be adjusted vertically using the seventh electric telescopic rod located on top of the clamping plates 30. This allows the clamping plates 30 to be moved to the top surface of any of the third conveyor belts 11. The second electric slider 29 can then slide inside the second chute 28 to clamp and fix the unqualified spinning paper tubes using the two clamping plates 30. Afterward, the sixth electric telescopic rod 27 is retracted to reset the clamping plates 30 as shown in the attached figure. Figure 10 As shown, the first electric rotating rod 31 is rotated 90 degrees counterclockwise, and then the second electric rotating rod 32 is rotated 90 degrees. After the two clamps 30 release the corresponding spinning paper tubes, the waste spinning paper tubes can be sent out for collection.

[0054] In addition, when it is necessary to test the strength of the spinning paper tube, the spinning paper tube to be tested can be clamped by two clips 30, and the spinning paper tube can be clamped to a certain extent by the two clips 30, so that the spinning paper tube is subjected to the same force as the preset test value, and then the strength of the spinning paper tube can be tested to determine whether it is qualified, thereby estimating the overall product quality. Whether the test pieces are qualified or not should be collected and recorded.

[0055] When the spinning paper tube outside the fixed cone 19 falls into the second through hole 21 at the top of the second mounting plate 9, if the spinning paper tube is stuck to the fixed cone 19, although the spinning paper tube has been detached from the fixed cone 19 by the second electric telescopic rod 18, some solidified glue will still remain on the outside of the fixed cone 19. The solidified glue will affect the subsequent support and fixation of the fixed cone 19 for other spinning paper tubes. Then, when the fixed cone 19 moves directly above the first mounting plate 8, the first mounting plate 8 is extended upward by the fourth electric telescopic rod 23, so that the fixed cone 19 can be inserted into the first through hole 20 at the top of the first mounting plate 8. The wiping cotton inside the first through hole 20 can clean the outside of the fixed cone 19 to ensure the cleanliness of the fixed cone 19. In addition, the recesses reserved on both sides of the second bracket 5 can also facilitate the replacement of the wiping cotton.
