An inner bracket is installed on one side of the outer bracket, and a drive roller is arranged on one side of the inner bracket. A drive motor is located above the drive roller, and an encoder fixing bracket is arranged on one side of the drive roller.

Description

Technical Field

[0001] This utility model belongs to the field of encoder feeding technology, and in particular relates to a dual encoder roller feeding mechanism. Background Technology

[0002] A dual encoder is a neural network model consisting of two encoders with identical structures. One encoder encodes the input text, and the other encoder encodes the text to be matched. The two encoders then calculate the similarity of the resulting vectors to determine the degree of similarity between the two texts. When using a dual encoder, it is necessary to feed the two encoders together.

[0003] The feeding mechanisms currently available on the market have the following problems when used:

[0004] 1. In traditional feeding mechanisms, the meter wheel has difficulty sensing the distance the material travels, which makes it prone to slippage or other abnormalities, resulting in inaccurate feeding and reduced feeding efficiency. Its anti-slipping effect is also poor.

[0005] 2. In traditional feeding mechanisms, when the encoder is performing encoding operations between the drive rollers, the encoder is easily driven by the drive rollers, making it prone to damage and resulting in poor protection. Utility Model Content

[0034] The inner support 2 includes a first rear mounting plate 71. A power mounting plate is provided on one side of the rear mounting plate 71.

The guide post 273 is installed inside the first rear mounting plate 71. The height screw is installed inside the guide sleeve 274. The first rear mounting plate 71 and the second rear mounting plate 72 have elastic elements and height screws 277 on their sides. An inner bracket 2 is installed on the side of the outer bracket 1. A drive roller 5 is added to the side of the inner bracket 2. The motor drives the drive roller 5 to move.

[0036] The outer support 1 includes a right upright plate 111, a rear plate 112, a bottom plate 113, a top plate 114, a left upright plate 116, an auxiliary plate 115, a cylinder mounting plate 118, and a guide rail mounting plate 117, which are interconnected to form the outer support 1 assembly. The guide rail mounting plate 117 has a guide rail 181 on its side, and a slider 182 on the side of the guide rail 181. A cylinder connecting plate C19 is mounted above the slider 182, and a cylinder connecting block B15 is mounted above the slider 182.

The cylinder connecting plate A13 has a cylinder connector 14 on the cylinder piston rod. The cylinder connecting plate has a pressure roller mounting plate 16 on its side and a pressure roller 171 below the pressure roller mounting plate 16. A first rear fixing plate 45 is added to the side of the second rear fixing plate 46. A guide post 41 is installed on the surface of the second rear fixing plate 46. A guide sleeve 22 is installed on the outside of the guide post 41. An elastic element 38 is added to the side of the second rear fixing plate 46. When the feeding mechanism is used, the second rear fixing plate 46 moves under the drive of the elastic element 38, causing the guide post 41 to move back and forth.

[0037] A dual encoder structure is provided between the two drive rollers 5 and on the surface of the base plate 113. By adding an encoder fixing bracket 3 to the surface of the base plate 18, the encoder is fixed more stably.

[0038] The dual encoder structure includes an encoder mounting base body 32. The surface of the encoder mounting base body 32 is provided with mounting holes, and a first slider 39 is provided inside the mounting holes. The encoder mounting base body 32 is mounted on the surface of the support vertical block 331. A spring 391 is provided between the first slider 39 and the support vertical block 331. A support horizontal block 332 is welded to the side of the support vertical block 331. The other end of the first slider 39 is pinned to the encoder mounting base body 32. A first slider 13 is added inside the outer support 1, and an intermediate support 11 is added outside the first slider 13. A spring 191 is installed on the side of the intermediate support 11, and an encoder fixing block 9 is added on the side of the intermediate support 11. The first slider 13 drives the spring 191 to prevent the meter wheel 8 from slipping during use.

[0039] The first slider 39 has an intermediate support 33 on its outer side. The intermediate support 33 is connected to the encoder fixing block 34. The encoder 35 is fixedly connected to the encoder fixing block 34. The meter wheel 37 is installed on the encoder shaft. When using the feeding mechanism, the encoder protective cover 31 is first installed on the outside of the encoder. The drive roller 5 is started and starts to run. When the drive roller 5 starts to move to feed the material, the encoder protective cover 31 protects the entire encoder to prevent the drive roller 5 from damaging the encoder, thus making its protection effect better.

[0040] The encoder mounting body 32 is externally fitted with an encoder protective cover 31. An elastic traction member 38 is provided between the encoder protective cover 31 and the intermediate support 33. The encoder can be conveniently recorded by the installed meter wheel.

[0041] Another encoder structure is installed inside the encoder mounting body 32, including spring 391, slider 182, limit pin 392, intermediate bracket 33, encoder fixing block 34, encoder 35, meter wheel 37, and elastic traction component 38.

[0042] The upper mounting plate and the lower mounting plate are equipped with another set of drive roller 5 mechanism, including drive roller 5 and bearing. A first gear 254 is provided above the end shaft of drive roller 5. A transmission gear is provided in the middle of the first gear 254. A bearing is provided in the transmission gear. The bearing is fixed to the upper mounting plate by clamping screws. By installing the bracket horizontal block 7 and the bracket vertical block 16 on the side of the encoder mounting body 15, the entire encoder mounting body 15 can be installed more stably. A coupling 36 is added to the bottom of the reducer 50 to facilitate the change of the angle of the reducer 50.

[0043] The working principle of the dual encoder roller feeding mechanism is as follows: When using this feeding mechanism, the stability of the encoder's measuring wheel 8 circumference is crucial. Even minor changes can affect the accuracy of the actual feeding results. Both encoders simultaneously contact the material and rotate with it, sensing the material's movement. If one encoder slips, the other is unlikely to slip. Traveling along the same path, the data from the slipping encoder will be lower than that from the non-slipping encoder. Therefore, the system adopts the larger data, i.e., the non-slipping encoder data. First, the encoder protective cover 6 is installed outside the encoder. Then, the drive roller 5 is started. When the drive roller 5 begins to move and feed, the encoder protective cover 6 protects the entire encoder, preventing damage from the drive roller 5 and improving its protective effect. The drive roller 5 then drives the feeding mechanism to start feeding. Only the reducer 50 needs to drive the power mounting plate 49 to prevent the motor speed from being too fast and damaging the feeding mechanism, effectively preventing slippage of the feeding mechanism.

[0044] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
