DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 6 As shown, this embodiment provides an embodiment of a paper winding roller bearing.

[0026] The paper reel bearing comprises a paper reel body 1 and a bearing body 2. The bearing body 2 is provided with a disassembly structure 3. The disassembly structure 3 comprises a plurality of support seats 4 installed on both sides of the paper reel body 1. A plurality of fixing frames 5 are fixedly installed on the support seats 4. A plurality of fixing blocks 6 are fixedly installed on the bearing body 2. A plug rod 7 connected with the fixing block 6 is movably installed on the fixing frame 5. A spring 8 connected with the paper reel body 1 is wound on the plug rod 7. Through the setting of the disassembly structure 3, the disassembly and replacement of the bearing body 2 can be conveniently performed. The bearing body 2 can be taken out without knocking. At the same time, the plurality of plug rods 7 are pulled up. Then, the bearing body 2 is placed on the side of the paper reel body 1 and pushed inward to the inside of the support seat 4. The plug rod 7 is loosened so that it is engaged with the fixing block 6 under the elastic action of the spring 8. The installation of the bearing body 2 can be completed. When disassembling, the plurality of plug rods 7 are directly pulled up to separate them from the fixing block 6. The bearing body 2 can be taken out. The disassembly is convenient and quick and it is not easy to damage the inner and outer rings of the bearing body 2.

[0027] One end of the insertion rod 7 is provided with an anti-slip pattern 9. The anti-slip pattern 9 can increase the friction force on the surface of one end of the insertion rod 7, making it difficult for people to slip their hands when pulling the insertion rod 7, thereby facilitating the disassembly and installation of the bearing body 2.

[0028] A plurality of sensors 10 are fixedly mounted on the paper reel body 1, and an emergency stop switch 11 electrically connected to the sensor 10 is fixedly mounted on the support seat 4. Through the setting of the sensor 10 and the emergency stop switch 11, the sensor 10 can detect the deviation of the paper during the paper reeling process and issue an alarm, and then the paper reel body 1 is urgently stopped through the emergency stop switch 11 to avoid damage to the paper.

[0029] A groove 12 is provided on the support seat 4, and a motor 13 is fixedly installed inside the groove 12. A first gear 14 is fixedly installed at the output end of the motor 13. A second gear 15 meshing with the first gear 14 is fixedly installed on the paper roller body 1. Through the arrangement of the groove 12, the motor 13, the first gear 14 and the second gear 15, the motor 13 is started to drive the first gear 14 to rotate. When the first gear 14 rotates, the second gear 15 also rotates. The paper roller body 1 starts to run driven by the second gear 15. Since the motor 13 is arranged on the inner side of the support seat 4, it can prevent people from accidentally touching the motor 13 and causing injuries.

[0030] A dust cover 16 connected to the support seat 4 is installed on the outer side of the groove 12, and a plurality of heat dissipation holes 17 are opened on the dust cover 16. The arrangement of the dust cover 16 and the heat dissipation holes 17 can prevent dust from entering the interior of the groove 12 and causing blockage of the motor 13. The heat dissipation holes 17 can dissipate the heat generated by the operation of the motor 13 to prevent the motor 13 from being damaged due to overheating.

[0031] The bearing body 2 is provided with a plurality of slide grooves 18, and a slider 19 connected to the paper roll body 1 is slidably connected inside the slide grooves 18. The arrangement of the slide grooves 18 and the slider 19 can reduce the friction between the paper roll body 1 and the bearing body 2, and facilitate the disassembly and installation of the bearing body 2.

[0032] The surface of the paper roll body 1 is provided with a rubber pad 20. The rubber pad 20 can increase the friction between the paper roll body 1 and the paper roll, preventing the paper roll from sliding or falling off during rotation or transportation, thereby improving production efficiency and safety.

[0033] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a paper roll bearing provided in this embodiment is as follows:

[0034] At the same time, pull up multiple insertion rods 7, then place the bearing body 2 on the side of the paper roller body 1 and push it inward to the inside of the support seat 4, loosen the insertion rod 7 so that it engages with the fixing block 6 under the elastic action of the spring 8, and the installation of the bearing body 2 is completed. When disassembling, directly pull up multiple insertion rods 7 to disengage them from the fixing block 6, and the bearing body 2 can be taken out. The disassembly is convenient and quick, and it is not easy to damage the inner and outer rings of the bearing body 2.

[0035] In summary, in this embodiment, according to a paper winding roller bearing of this embodiment, the friction force on the surface of one end of the insertion rod 7 can be increased by setting the anti-slip pattern 9, so that the hand of the personnel is not easy to slip when pulling the insertion rod 7, and the disassembly and installation of the bearing body 2 are convenient. Through the setting of the sensor 10 and the emergency stop switch 11, the sensor 10 can detect the deviation of the paper during the paper winding process and issue an alarm, and then the emergency stop switch 11 is used to stop the paper winding roller body 1 urgently to avoid paper damage. Through the setting of the groove 12, the motor 13, the first gear 14 and the second gear 15, The starting motor 13 drives the first gear 14 to rotate. When the first gear 14 rotates, the second gear 15 also rotates. The paper roll body 1 starts to run under the drive of the second gear 15. Since the motor 13 is arranged on the inner side of the support seat 4, it can prevent people from accidentally touching the motor 13 and causing injuries. The dust cover 16 and the heat dissipation hole 17 can prevent dust from entering the inside of the groove 12 and causing the motor 13 to be blocked. The heat dissipation hole 17 can dissipate the heat generated by the operation of the motor 13 to prevent the motor 13 from being damaged due to overheating. The slide groove 18 and the slider 19 can reduce the friction between the paper roll body 1 and the bearing body 2, and facilitate the disassembly and installation of the bearing body 2. The rubber pad 20 can increase the friction between the paper roll body 1 and the paper roll, and prevent the paper roll from sliding or falling off during rotation or transportation, thereby improving production efficiency and safety.

[0036] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
