Description

Technical Field

[0001] The utility model relates to the field of feeding devices, in particular to a feeding device for preparing melamine film paper. Background Art

[0002] Melamine coated paper is a special paper made of melamine resin as the base material. It has good waterproof, corrosion-resistant and high-temperature resistant properties and is widely used in food, medicine, electronics, electrical appliances, automobiles and construction. In the process of preparing melamine coated paper, a feeding device is required, and a conveyor belt is often used as a feeding device to feed the material.

[0003] In the existing conveyor belt structure, in order to ensure the stability of the conveyor belt, it is necessary to tension the conveyor belt after it is sleeved on the conveyor roller, and bolts are generally used for tensioning. However, in the existing conveyor belt structure, the support blocks at both ends of the conveyor roller are tensioned by bolts respectively, and the two ends of the conveying pipe cannot be tensioned at the same time. In the process of tensioning and adjusting, the tensioning degree at both ends of the conveyor roller is likely to be inconsistent. When the tensioning degree at both ends of the conveyor roller is inconsistent, the tensioning effect of the conveyor roller on the conveyor belt will be different, which is very likely to cause the conveyor belt to deviate, thereby affecting the normal conveying and feeding work. At the same time, the tensioning and adjusting of the two ends of the conveyor roller separately requires more time to operate, and the operation convenience is poor. In addition, in the existing conveyor belt structure, the conveyor belt is tensioned and supported only by the conveyor rollers at both ends, and the middle part of the conveyor belt cannot be effectively supported. When the conveyed material is large, it will affect the normal conveying. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-Figure 5 As shown, a feeding device for preparing melamine film paper comprises a conveying frame 1, a conveying roller 2 is provided on the conveying frame 1, and a conveying belt 3 is sleeved on the conveying roller 2, a supporting assembly 6 is provided on the inner side of the conveying frame 1, and the supporting assembly 6 contacts the conveying belt 3, a tensioning assembly 7 is fixed on the conveying frame 1, a bearing seat 8 is provided on one end of the conveying frame 1 and the tensioning assembly 7, two conveying rollers 2 are respectively connected to the conveying frame 1 and the bearing seat 8 on the tensioning assembly 7, a supporting leg 5 is fixed at the lower end of the conveying frame 1, and a driving motor 4 is provided on the conveying frame 1, the conveying roller 2 installed at the end of the conveying frame 1 is connected to the driving motor 4, the supporting assembly 6 comprises a supporting frame 601 and a supporting roller 602, the supporting roller 602 is rotatably installed on the supporting frame 601, and the supporting frame 601 is fixedly installed on the inner side of the conveying frame 1, through the provided supporting assembly 6, the supporting roller 602 plays an auxiliary supporting role for the conveying belt 3, and the supporting roller 602 can rotate on the supporting frame 601, so as to ensure that the conveying belt 3 can be normally transported even if there are more materials on it.

[0020] When the device is used for loading, the conveyor frame 1 is stably placed by the support legs 5, and the support assembly 6 is installed on the inner side of the conveyor frame 1. At the same time, a tensioning assembly 7 for tensioning the conveyor belt 3 is arranged on the conveyor frame 1. After starting the drive motor 4, the drive motor 4 drives the conveyor roller 2 on the corresponding bearing seat 8 to rotate, thereby driving the conveyor belt 3 to run. The material is placed on the conveyor belt 3 for transportation to complete the loading work. In this process, the support roller 602 on the inner side of the support frame 601 plays an auxiliary supporting role for the conveyor belt 3. At the same time, the support roller 602 can rotate on the support frame 601 without affecting the normal operation of the conveyor belt 3. When necessary, it can be adjusted through the tensioning assembly 7, which is convenient for disassembling the conveyor belt 3 for replacement and other operations. When the conveyor belt 3 is installed again, the tensioning assembly 7 can be used for tensioning adjustment. The structure is simple and the use effect is excellent.

[0021] Through the above implementation scheme, the tensioning assembly 7 includes a first fixed rod 701, a second fixed rod 702, an adjusting plate 704, a movable plate 705, a servo motor 707 and a screw rod 708. The first fixed rod 701 and the second fixed rod 702 are installed on the conveying frame 1, the adjusting plate 704 runs through the first fixed rod 701, the movable plate 705 is installed at the end of the adjusting plate 704, the servo motor 707 is connected to the screw rod 708, and the servo motor 707 is installed on the first fixed rod 701. The tensioning assembly 7 also includes a mounting plate 703, a connecting screw 706 and a nut seat 709. The mounting plate 703 is fixedly connected to the adjusting plate 704, the connecting screw 706 is arranged on the adjusting plate 704, and the end of the connecting screw 706 is threadedly connected to the movable plate 705, and the screw rod 708 is located between the first fixed rod 701 and the second fixed rod 702. Between the fixed rods 702, the nut seat 709 is fixed on the movable plate 705, and the nut seat 709 is sleeved on the screw rod 708, and the screw rod 708 is threadedly connected to the nut seat 709. The tensioning component 7 is adopted, and the mounting plate 703 and the adjustment plate 704 connected to the bearing seat 8 are arranged on the first fixed rod 701. When used in conjunction with the servo motor 707, the screw rod 708 and the nut seat 709 and other structures, the position of the mounting plate 703 can be adjusted at the same time, so as to achieve synchronous adjustment of the two bearing seats 8 at the ends of the same conveyor roller 2, and ensure that the corresponding conveyor rollers 2 have the same force on the conveyor belt 3 after adjustment, so as to avoid the deviation of the conveyor belt 3. The servo motor 707, the screw rod 708 and the nut seat 709 are used for adjustment, and the adjustment is accurate and fast. After adjustment, it has a self-locking effect and can ensure stability after adjustment.

[0022] When adjusting the tensioning assembly 7, after starting the servo motor 707 on the first fixed rod 701, the servo motor 707 drives the screw rod 708 between the first fixed rod 701 and the second fixed rod 702 to rotate. Since the screw rod 708 is threadedly connected with the nut seat 709, when the screw rod 708 rotates, the nut seat 709 is forced to move the movable plate 705, thereby driving the adjustment plate 704 to move on the first fixed rod 701, and the mounting plate 703 moves with the adjustment plate 704, thereby driving the corresponding bearing seat 8 and the conveying roller 2 to move. After the movement, the conveyor belt 3 is tensioned to ensure the normal operation of the conveyor belt 3. In the process of the tensioning assembly 7 adjusting the corresponding conveyor roller 2, the two adjustment plates 704 move synchronously on the first fixed rod 701, so that the corresponding two bearing seats 8 can be moved synchronously, ensuring that the movement strokes of the two ends of the conveyor roller 2 are consistent, avoiding adjustment differences, and ensuring that the subsequent conveyor belt 3 will not deviate during operation. At the same time, the screw rod 708 and the nut seat 709 on the servo motor 707 have a self-locking effect, which can ensure the stability of the entire tensioning assembly 7 after adjustment and ensure the stability of the conveyor roller 2.
