Description

Technical Field

[0002] A paper inserter is a device for automatically inserting insulating paper, mainly used in the production process of small and medium-sized motor stators. The paper feeding mechanism is located within the paper inserter. The insulating paper is fed by two pressure rollers driven by actuators in the paper pressing mechanism, causing the paper to be pressed and pressed to the required standard during the feeding process.

[0003] During the operation of a paper insertion machine, the pressure rollers in the paper press, which are used to shape the insulating paper, need to be changed according to the specifications of the insulating paper being processed. However, the traditional paper feeding mechanism used in paper insertion machines, while meeting basic paper feeding needs, has certain limitations when facing high-efficiency and diversified production demands. The main problems include: long time consumption and complex operation when changing the paper feeding mechanism, which affects the overall efficiency of the production line.

[0004] To address the above problems, this invention proposes a quick-change paper feeding mechanism suitable for production environments requiring frequent changes to different paper types or specifications. It enables rapid and convenient replacement of the paper feeding components within the paper inserter. The mechanism employs a modular design, allowing for quick disassembly and reassembly of the paper feeding components, reducing replacement time and operational complexity. Utility Model Content

[0024] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0025] Please see Figures 1 to 8 This is a structural schematic diagram of a quick-change paper feeding mechanism provided by this utility model. The quick-change paper feeding mechanism includes a polymerization module 10, an outer frame 20 for fixing the polymerization module 10, a transmission structure 30 for assisting in fixing the polymerization module 10, a cylinder structure 40 for assisting in fixing the outer frame 20 and the polymerization module 10, and a quick-change long rod 50 that passes through and connects the outer frame 20 and the polymerization module 10. It is conceivable that the quick-change paper feeding mechanism also includes other functional modules, such as mounting connectors, which are technologies known to those skilled in the art and will not be described in detail here.

[0026] The aggregation module 10 includes an aggregation frame 11 and a paper pressing device 12 disposed in the aggregation frame 11.

[0027] The polymer frame 11 has two first side plates 111. Multiple long rods connect the corners of the two opposite first side plates 111 for detachable fixation. Multiple connecting strips 112 are detachably provided at both ends of the long side of each opposite first side plate 111. A handle 113 is detachably provided above the two opposite first side plates 111. The handle 113 is used for easy handling of the polymer frame 11. The polymer frame 11 is used to modularly arrange the paper pressing device 12, facilitating quick access to the paper pressing device 12 during assembly and disassembly.

[0028] The first side plate 111 includes at least one fixed shaft mounting groove 1111, at least one rotating shaft mounting hole 1112 disposed below the fixed shaft mounting groove 1111, at least one observation groove 1113 disposed between the fixed shaft mounting groove 1111 and the rotating shaft mounting hole 1112, and at least one fixing rod mounting hole 1114 communicating with the top surface of the first side plate 111 and the fixed shaft mounting groove 1111. The fixed shaft mounting groove 1111 and the rotating shaft mounting hole 1112 are used to cooperate in installing the paper pressing device 12. The observation groove 1113 is used to observe and clean the paper pressing status of the paper pressing device 12. The fixing rod mounting hole 1114 is used to assist the paper pressing device 12 in being installed in the polymer frame 11.

[0029] The paper pressing device 12 includes a rotating shaft 121 passing through the rotating shaft mounting hole 1112, two bearings 122 installed between the rotating shaft mounting hole 1112 and the rotating shaft 121, two limiting rings 123 attached to different first side plates 111, a first paper pressing wheel 124 sleeved on the outer periphery of the rotating shaft 121, a fixed shaft 125 installed in the fixed shaft mounting groove 1111, and a second paper pressing wheel 126 sleeved on the outer periphery of the fixed shaft 125.

[0030] The rotating shaft 121 is rotatably connected at both ends to the rotating shaft mounting holes 1112 of the two opposite first side plates 111 via external bearings 122. The bearings 122 support the rotation of the rotating shaft 121. One end of the rotating shaft 121 facing the transmission structure 30 passes through the first side plate 111 and is provided with a snap-fit ​​ring 1211 and a insertion hole 1212. The other end is provided with a stop cap 1213 to axially limit the bearing 122. The diameter of the snap-fit ​​ring 1211 is larger than the diameter of the rotating shaft 121 to increase the contact area for easy connection with the transmission structure 30. The snap-fit ​​ring 1211 has a snap-fit ​​groove 12111 on the side facing the transmission structure 30. The snap-fit ​​groove 12111 is linearly arranged, and the snap-fit ​​ring 1211 passes through the opening of the insertion hole 1212. The snap-fit ​​groove 12111 and the insertion hole 1212 are used for connection with the transmission structure 30, which will be described in detail below with reference to the transmission structure 30.

[0031] Two limiting rings 123 are respectively located on the opposing end faces of the two first side plates 111 and are disposed at the opening of the rotating shaft mounting hole 1112. The limiting rings 123 block the position of the bearing 122. On the side near the transmission structure 30, the limiting rings 123 are used to prevent the bearing 122 from moving to confirm that the transmission structure 30 is fitted into the insertion hole 1212. On the side near the cylinder structure 40, a limiting step 1214 is formed between the bearing 122 and the inner sidewall of the rotating shaft mounting hole 1112. The limiting step 1214 is used to engage with the cylinder structure 40 to fix the rotating shaft 121. The setting of the limiting step 1214 is related to the cylinder structure 40 described below, which will be explained in detail below.

[0032] The first pressure roller 124 includes a pressure roller body 1241 mounted on the rotating shaft 121 and a transmission gear 1242 mounted on the side of the pressure roller body 1241. A limiting block is provided between the first pressure roller 124 and the bearing 122 to determine its position on the rotating shaft 121. The first pressure roller 124 rotates together with the rotating shaft 121, and the transmission gear 1242 is used to drive the second pressure roller 126 to rotate.

[0033] The fixed shaft 125 has a connecting groove 1251 at each end. The fixed shaft 125 is detachably fixed to the first side plate 111 by a fixing rod 1252. One end of the fixing rod 1252 is installed in the connecting groove 1251, and the other end is movably connected to the fixing rod mounting hole 1114. The fixing rod 1252 can be a screw. By adjusting the distance of the fixing rod 1252 in the fixing shaft mounting groove 1111, the distance between the first and second paper pressing rollers 124 and 126 is changed, thereby changing the groove depth on the product surface. A second paper pressing roller 126 is rotatably mounted on the fixed shaft 125.

[0034] The second pressure roller 126 includes a second pressure roller body 1261 mounted on the fixed shaft 125, and a second transmission gear 1262 mounted on the side of the second pressure roller body 1261. The second pressure roller body 1261 is rotatably sleeved on the outer periphery of the fixed shaft 125 via a second bearing, and a limiting block is provided between the second pressure roller 126 and the second bearing to correspond with the first pressure roller 124. The second transmission gear 1262 meshes with the transmission gear 1242, driving the second pressure roller body 1261 to rotate while the fixed shaft 125 remains stationary.

[0035] The transmission structure 30 is located on one side of the outer frame 20, and the cylinder structure 40 is located on the opposite side. The aggregate frame 11 is disposed within the outer frame 20. The outer frame 20 includes two opposing second side plates 21. The second side plates 21 are fixed in a well shape by connecting plates. Each opposing second side plate 21 has a first mounting hole 211 for mounting the transmission structure 30 and the cylinder structure 40, a second mounting hole 212 for mounting the quick-change long rod 50, and a locking hole 213 located on the second side plate 21 near the transmission structure 30. The locking hole 213 is located on the top surface of the second side plate 21 and connects to the first mounting hole 211. The locking hole 213 assists in the installation of the quick-change long rod 50.

[0036] The transmission structure 30 includes a transmission shaft 31, a mounting post 32 disposed at the end of the transmission shaft 31 facing the rotating shaft 121, and a snap-fit ​​member 33 disposed at one end of the transmission shaft 31 facing the rotating shaft 121. An external bearing 122 of the transmission shaft 31 is mounted in the first mounting hole 211 and is aligned with the rotating shaft 121. The mounting post 32 is inserted into the insertion hole 1212, connecting the transmission structure 30 and the rotating shaft 121, and also supporting one side of the bottom of the aggregation module 10. Two snap-fit ​​blocks 331 are fitted onto the side of the snap-fit ​​member 33 facing the rotating shaft 121. The shape of the snap-fit ​​blocks 331 corresponds to the snap-fit ​​groove 12111. The snap-fit ​​blocks 331 are detachably fixed to the transmission shaft 31 via a connector. The locking blocks 331 are configured to engage with the locking slots 12111, allowing the drive shaft 31 to drive the locking ring 1211 to transmit power to the rotating shaft 121 via the locking blocks 331. The drive shaft 31 is connected to an external rotary motor via a belt, so that when the rotary motor is working, the drive shaft 31 rotates at the same speed under the action of the belt, and the locking blocks 331 drive the locking ring 1211 to rotate.

[0037] The cylinder structure 40 is provided with a limiting and fixing block 41 on the side facing the rotating shaft 121. When the cylinder structure 40 is running, the limiting and fixing block 41 moves towards the rotating shaft 121 and engages with the limiting step 1214, thereby supporting the other side of the bottom of the aggregation module 10 and fixing the aggregation frame 11 to the outer frame 20.

[0038] The quick-change long rod 50 passes through the second mounting hole 212 to assist in the detachable fixation of the polymer frame 11 to the outer frame 20. The quick-change long rod 50 is located on the side of the polymer frame 11 away from the connecting strip 112. The quick-change long rod 50 includes a rod head 51 and a rod body 52 connecting the rod head 51. The diameter of the rod head 51 is larger than the diameter of the rod body 52. ​​The rod head 51 is snapped onto the outside of the second side plate 21, and the rod body 52 passes through the first and second side plates 111 and 21, thereby fixing the top of the polymer module 10 through the quick-change long rod 50. The rod body 52 is locked in the second mounting hole 212 by a connector installed in the locking hole 213.

[0039] When the polymerization module 10 needs to be replaced, push the side of the polymerization frame 11 with the blocking cover 1213 into the outer frame 20 along the second side plate 21 near the cylinder structure 40, and move the polymerization module 10 along the edge. Once the rotating shaft 121 is aligned with the center of the first mounting hole 211 and the transmission shaft 31, insert the mounting post 32 into the insertion hole 1212, and the polymerization module 10 moves towards the transmission structure 30. The snap-fit ​​block 331 engages with the snap-fit ​​groove 12111, activating the cylinder structure 40. The cylinder structure 40 pushes the limiting fixing block 41 to engage with the limiting step 1214, supporting the other side of the bottom of the polymerization module 10. Use the quick-change long rod 50 through the second mounting hole 212 to fix the top of the polymerization module 10, thereby fixing the polymerization frame 11 in the outer frame 20.

[0040] Compared with the prior art, the quick-change paper feeding mechanism provided by this utility model enables the rapid replacement of the paper pressing device 12 by setting the aggregation frame 11 module, the quick-change long rod 50, the cylinder structure 40, and the transmission structure 30. The paper pressing device 12 and the aggregation frame 11 are modularly arranged to form the aggregation module 10, realizing the rapid replacement of the paper pressing device 12 of different specifications. The quick-change long rod 50 connects the aggregation module 10 and the outer frame 20, fixing the top of the aggregation module 10. The locking block 331 of the transmission device engages with the locking ring 1211 of the paper pressing device 12, and the mounting post 32 is inserted into the insertion hole 1212, connecting the rotating shaft 121 to the transmission structure 30, thereby supporting one side of the bottom of the aggregation module 10. The cylinder structure 40 pushes the limiting and fixing block 41, and the limiting and fixing block 41 moves toward the rotating shaft 121 and engages with the limiting step 1214, thereby supporting the other side of the bottom of the aggregation module 10.
