Description

Technical Field

[0001] This utility model relates to the technical field of paper tubes, specifically to a paper tube drying device. Background Technology

[0002] Paper tubes: These are tubular objects made from paper. Most paper tubes are spiral or seamless. Drying equipment is required during the paper tube manufacturing process.

[0003] The paper tube drying device disclosed in patent application CN219572480U includes a drying chamber with a radiator installed on the inner wall and a heat exchange component installed on top of the radiator. This device heats the gas through the radiator and the heat exchange component, then uses a high-temperature blower to deliver the hot gas into the drying chamber. A circulating fan circulates the hot air inside the drying chamber, rapidly raising the temperature and improving heating efficiency. This enhances overall efficiency. A dehumidifying fan and dehumidifying pipes extract water vapor generated during the paper tube drying process. The condensate is stored in a condensate recovery tank for reuse, reducing water waste, lowering production costs, and ultimately increasing the company's economic benefits.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] When drying paper tubes, they are usually placed directly inside the dryer. However, because paper tubes are cylindrical, it is difficult to heat them evenly when they are placed inside the dryer, which takes a lot of time and reduces the drying rate. Utility Model Content

[0006] The purpose of this invention is to provide a paper tube drying device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A paper tube drying device includes a dryer, a controller, and a door. The controller is fixedly installed on one side of the dryer, and the door is hinged to one side of the dryer. The dryer has a placement tray inside, and a positioning mechanism for fixing the paper tube is provided at the bottom of the placement tray.

[0009] A transmission mechanism, which is fixedly mounted on one side of the dryer;

[0010] The transmission mechanism includes a motor fixedly connected to one side of the dryer. The output end of the motor extends into the interior of the dryer and is fixedly connected to a lead screw. A transmission block is connected to the surface of the lead screw. A rotating shaft is provided at the bottom of the transmission block, and a gear is rotatably connected to the shaft. The bottom of the gear is fixedly connected to the top of the mounting plate. A toothed plate that cooperates with the gear is fixedly connected to the inner wall of the dryer.

[0011] The transmission mechanism allows several paper tubes to be fixed to the bottom of the mounting tray by a positioning mechanism after the machine door is opened. The dryer is then started to dry the paper tubes. Simultaneously, the motor is activated, driving a lead screw to rotate. The lead screw then drives a transmission block, which, constrained by a sliding block, moves back and forth along a sliding groove. This, in turn, drives the rotating shaft, gears, and mounting tray to move back and forth. The paper tubes also move back and forth with the mounting tray. Meanwhile, the gears contact the gear plate, causing them to rotate around the rotating shaft, which in turn drives the mounting tray and paper tubes to rotate. By continuously changing the position of the paper tubes inside the dryer, the paper tubes can be heated evenly, thus improving the drying effect.

[0012] Preferably, the positioning mechanism includes a dovetail groove formed at the bottom of the placement tray, a spring is provided inside the dovetail groove, dovetail blocks are fixedly connected to both ends of the spring, a movable block is fixedly connected to the bottom of the dovetail block, and a clamping block is fixedly connected to the side of each of the two movable blocks that are far apart from each other.

[0013] By setting up a positioning mechanism, pressing two moving blocks simultaneously will cause them to move two clamping blocks closer to the spring until the distance between the two moving blocks is less than the inner diameter of the paper tube. Then, the paper tube is removed and placed over the surfaces of the two clamping blocks. Releasing the moving blocks will cause the spring force to push the moving blocks and clamping blocks away from the spring until the silicone block on one side of the clamping block makes tight contact with the inner wall of the paper tube, thus securing the paper tube. After drying, pressing the two moving blocks again will easily remove the paper tube.

[0014] Preferably, one end of the lead screw is provided with a bearing seat, and is rotatably connected to the inner wall of the dryer through the bearing seat.

[0015] By setting up a bearing housing, the lead screw can be supported, restricting its rotation to only around the bearing housing, and improving the smoothness of its fixation during rotation.

[0016] Preferably, a sliding block is fixedly connected to the top of the transmission block, and a sliding groove is provided on the inner wall of the dryer to cooperate with the sliding block.

[0017] By setting up a sliding block and a sliding groove, when the lead screw rotates to drive the transmission block, the transmission block can only reciprocate along the trajectory of the sliding groove under the restriction of the sliding block.

[0018] Preferably, a silicone block is fixedly connected to each of the two clamping blocks on the side that is far apart from each other, and the silicone block is arc-shaped.

[0019] By setting up silicone blocks, a buffering effect can be achieved when the clamping block comes into contact with the inner wall of the paper tube, thus preventing damage to the inner wall of the paper tube.

[0020] Preferably, the silicone block has anti-slip texture on one side.

[0021] By setting anti-slip textures, the stability of the paper tube can be improved, thus preventing slippage.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. This utility model, by setting up a transmission mechanism, allows several paper tubes to be fixed to the bottom of the placement tray by a positioning mechanism after the machine door is opened. The dryer is then started to dry the paper tubes. At the same time, the motor is started, which drives the lead screw to rotate. The lead screw then drives the transmission block. Under the restriction of the sliding block, the transmission block moves back and forth along the trajectory of the sliding groove, thereby driving the rotating shaft, gears, and placement tray to move back and forth. The paper tubes also move back and forth with the placement tray. Meanwhile, the gears contact the gear plate, causing the gears to rotate around the rotating shaft, which in turn drives the placement tray and paper tubes to rotate. By continuously changing the position of the paper tubes inside the dryer, the paper tubes can be heated evenly, thereby improving the drying effect.

[0024] 2. This utility model, by setting a positioning mechanism, allows two moving blocks to be pressed simultaneously. The moving blocks will drive two clamping blocks to move closer to the spring until the distance between the two moving blocks is less than the inner diameter of the paper tube. Then, the paper tube is taken out and placed on the surface of the two clamping blocks. After releasing the moving blocks, the elastic force generated by the spring will push the moving blocks and clamping blocks to move away from the spring until the silicone block on one side of the clamping block is in close contact with the inner wall of the paper tube, thus fixing the paper tube. After drying, pressing the two moving blocks again will allow the paper tube to be easily removed. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1 - Figure 6 This utility model provides a technical solution:

[0034] Example 1:

[0035] A paper tube drying device includes a dryer 1, a controller 2 and a door 3. The controller 2 is fixedly installed on one side of the dryer 1, and the door 3 is hinged to one side of the dryer 1. The dryer 1 is provided with a placement tray 4, and the bottom of the placement tray 4 is provided with a positioning mechanism for fixing the paper tube.

[0036] The transmission mechanism is fixedly installed on one side of the dryer 1;

[0037] The transmission mechanism includes a motor 10 fixedly connected to one side of the dryer 1. The output end of the motor 10 extends into the interior of the dryer 1 and is fixedly connected to a lead screw 11. A transmission block 12 is connected to the surface of the lead screw 11. A rotating shaft 13 is provided at the bottom of the transmission block 12, and a gear 14 is rotatably connected through the rotating shaft 13. The bottom of the gear 14 is fixedly connected to the top of the mounting plate 4. A toothed plate 15 that cooperates with the gear 14 is fixedly connected to the inner wall of the dryer 1.

[0038] In this embodiment, considering that existing dryers 1, when drying paper tubes, are cylindrical, it is difficult to heat them evenly inside the dryer 1, requiring a lot of time and thus reducing the drying rate, a transmission mechanism is set up. After opening the machine door 3 and fixing several paper tubes to the bottom of the placement tray 4 through the positioning mechanism, the dryer 1 is started to dry the paper tubes. At the same time, the motor 10 is started, which drives the lead screw 11 to rotate. The lead screw 11 then drives the transmission block 12. Under the restriction of the sliding block 17, the transmission block 12 moves back and forth along the trajectory of the sliding groove 18, thereby driving the rotating shaft 13, gear 14, and placement tray 4 to move back and forth. The paper tubes also move back and forth with the placement tray 4. At the same time, the gear 14 contacts the toothed plate 15, causing the gear 14 to rotate around the rotating shaft 13, which in turn drives the placement tray 4 and the paper tubes to rotate. By continuously changing the position of the paper tubes inside the dryer 1, the paper tubes can be heated evenly, thereby improving the drying effect.

[0039] One end of the lead screw 11 is provided with a bearing seat 16, and is rotatably connected to the inner wall of the dryer 1 through the bearing seat 16.

[0040] In this application, by setting the bearing seat 16, the lead screw 11 can be supported, restricting the lead screw 11 to rotate only around the bearing seat 16, and improving the smoothness of its fixation during rotation.

[0041] A sliding block 17 is fixedly connected to the top of the transmission block 12, and a sliding groove 18 is provided on the inner wall of the dryer 1 to cooperate with the sliding block 17.

[0042] In this application, by setting a sliding block 17 and a sliding groove 18, when the lead screw 11 rotates to transmit power to the transmission block 12, the transmission block 12 can only reciprocate along the trajectory of the sliding groove 18 under the restriction of the sliding block 17.

[0043] Example 2:

[0044] The positioning mechanism includes a dovetail groove 5 at the bottom of the placement plate 4. A spring 6 is installed inside the dovetail groove 5. Dovetail blocks 7 are fixedly connected to both ends of the spring 6. A movable block 8 is fixedly connected to the bottom of the dovetail block 7. A clamping block 9 is fixedly connected to the side of the two movable blocks 8 that are far apart from each other.

[0045] In this application, by setting a positioning mechanism, by pressing two moving blocks 8 simultaneously, the moving blocks 8 will drive the two clamping blocks 9 to move closer to the spring 6 until the distance between the two moving blocks 8 is less than the inner diameter of the paper tube. Then, the paper tube is taken out and placed on the surface of the two clamping blocks 9. After releasing the moving blocks 8, the elastic force generated by the spring 6 will push the moving blocks 8 and the clamping blocks 9 to move away from the spring 6 until the silicone block 19 on the side of the clamping block 9 is in close contact with the inner wall of the paper tube, thus completing the fixation of the paper tube. After drying, pressing the two moving blocks 8 again will make the paper tube easy to remove.

[0046] Two clamping blocks 9 are fixedly connected to silicone blocks 19 on the opposite sides of each other. The silicone blocks 19 are arc-shaped.

[0047] In this application, by setting the silicone block 19, a buffering effect can be achieved when the clamping block 9 comes into contact with the inner wall of the paper tube, so as to avoid damage to the inner wall of the paper tube;

[0048] It should be noted that silicone block 19 is made of high-temperature resistant silicone and will not deform due to high temperatures.

[0049] The silicone block 19 has anti-slip texture 20 on one side.

[0050] By setting anti-slip texture 20 in this application, the stability of fixing the paper tube can be improved, thus playing an anti-slip role.

[0051] Working principle: By opening the machine door 3 and simultaneously pressing the two moving blocks 8, the moving blocks 8 will drive the two clamping blocks 9 to move closer to the spring 6 until the distance between the two moving blocks 8 is less than the inner diameter of the paper tube. Then, remove the paper tube and place it on the surface of the two clamping blocks 9. After releasing the moving blocks 8, the elastic force generated by the spring 6 will push the moving blocks 8 and clamping blocks 9 to move away from the spring 6 until the silicone block 19 on one side of the clamping block 9 is in close contact with the inner wall of the paper tube, thus completing the fixing of the paper tube. Fix multiple paper tubes to the bottom of the placement tray 4 in the same way. Then close the machine door 3 and start the dryer 1 to dry the paper tubes. While the machine is drying, the motor 10 is started. The motor 10 drives the lead screw 11 to rotate, which in turn drives the transmission block 12. Under the restriction of the sliding block 17, the transmission block 12 moves back and forth along the trajectory of the sliding groove 18, thereby driving the rotating shaft 13, gear 14 and mounting plate 4 to move back and forth. The paper tube also moves back and forth with the mounting plate 4. At the same time, the gear 14 contacts the toothed plate 15, causing the gear 14 to rotate around the rotating shaft 13, which in turn drives the mounting plate 4 and the paper tube to rotate. By continuously changing the position of the paper tube inside the dryer 1, the paper tube can be heated evenly, thereby improving the drying effect.

[0052] It should be noted that the motor 10 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art, and the specific composition and principle of the power supply of the motor 10 are clear to those skilled in the art, so they will not be described in detail here.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
