Description

Technical Field

[0001] The utility model relates to the field of waste paper recycling, in particular to a stable and uniform waste paper feeding device. Background Art

[0002] In the process of recycling waste paper as raw material into base paper, the waste paper is packaged into waste paper blocks, and then the waste paper blocks are transported to the recycling equipment through the transmission equipment, so as to gradually complete the base paper preparation work such as kraft paper for the waste paper blocks;

[0003] In the prior art, before the waste paper enters the processing equipment, the feeding port of the processing equipment is relatively high, and an inclined conveying equipment is required to convey the waste paper blocks during transmission. However, since the inclined conveying equipment has a slope, when conveying the waste paper blocks, due to gravity, the compacted and heavy waste paper blocks will roll down on the conveying equipment, resulting in the accumulation of waste paper blocks, and the transportation efficiency is greatly reduced.

[0004] The existing patent (publication number: CN217417524U) discloses a transmission structure for waste paper processing. The transmission structure of this device can press and hold waste paper blocks for transmission, and the waste paper blocks are not prone to slipping and rolling, which does not affect the transmission of the waste paper blocks. It is also convenient to limit the position of the waste paper so that the position of the waste paper does not shift during the transmission process. However, this device limits the waste paper blocks by pressing and holding. When pressing and holding, on the one hand, the pressure borne by the conveying device is increased, so that the conveying device needs more power to convey the waste paper blocks. On the other hand, the pressing and holding component is arranged above the conveying device, which limits the size of the conveying. When some relatively large waste paper blocks need to be transported by the conveying device, the waste paper blocks need to be divided, which increases the steps of recycling and reduces the recycling efficiency.

[0024] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] like Figure 1-6 As shown, a stable and uniform waste paper feeding device includes a bracket 1, a transmission wheel 2, a motor 3, a conveyor belt 4, a fixed plate 5 and a baffle 6; the bracket 1 is rotatably connected to two transmission wheels 2 distributed front and back; the transmission shaft of the front transmission wheel 2 is fixedly connected to the motor 3, and the motor 3 is fixedly connected to the bracket 1; the two transmission wheels 2 are wound around a conveyor belt 4; the bracket 1 is fixedly connected to two fixed plates 5; each fixed plate 5 is fixedly connected to a baffle 6, and the baffle 6 is in contact with the conveyor belt 4;

[0026] It also includes a connecting plate 101, a fixing component and a limiting plate 105. The connecting plate 101 is fixedly connected to the conveyor belt 4, and the connecting plate 101 passes through the conveyor belt 4. Each connecting plate 101 is connected to four fixing components. All the fixing plates 5 are fixedly connected to a limiting plate 105, and the limiting plate 105 is located inside the conveyor belt 4, and the limiting plate 105 is in contact with the fixing component on the upper part of the conveyor belt 4, and the front part of the limiting plate 105 is a bending part.

[0027] The fixed component at the upper left corner of the conveyor belt 4 includes a first elastic member 102, an extrusion block 103 and an insertion block 104; the connecting plate 101 is fixedly connected to two first elastic members 102; all the first elastic members 102 are fixedly connected to an extrusion block 103; the extrusion block 103 is fixedly connected to the insertion block 104, and the insertion block 104 passes through the connecting plate 101.

[0028] A roller is disposed at the bottom of the extrusion block 103 , and the roller of the extrusion block 103 can reduce the friction between the extrusion block 103 and the limiting plate 105 .

[0029] The inserting block 104 is provided with an inclined surface, and the inclined surface faces forward. The inserting block 104 is provided with only one inclined surface, which can further prevent the waste paper block from rolling down.

[0030] A scraping assembly is also included. Each connecting plate 101 is connected to a scraping assembly. The position of the scraping assembly corresponds to the position of the plug-in block 104 , and the scraping assembly contacts the plug-in block 104 at the corresponding position.

[0031] The scraping assembly at the upper left corner of the conveyor belt 4 includes a sliding rod 201, a scraper 202 and a second elastic member 203; the connecting plate 101 is fixedly connected to the two sliding rods 201; the two sliding rods 201 are slidably connected to a scraper 202; each sliding rod 201 is fixedly connected to a second elastic member 203, and the second elastic member 203 is fixedly connected to the scraper 202.

[0032] Before using the device, the rear part of the device is connected to the waste paper recycling equipment, the front part of the device is connected to the waste paper conveying equipment, and an external cleaning nozzle is installed under the conveyor belt 4. Then the motor 3 starts to work, driving the transmission wheel 2 to start rotating, and the transmission wheel 2 drives the conveyor belt 4 to start rotating. Then the waste paper conveying equipment dumps the waste paper blocks onto the conveyor belt 4, and the waste paper blocks can be transported to the waste paper recycling equipment. However, in this process, since the waste paper blocks climb on the inclined conveyor belt 4, they will inevitably roll down during the transportation process of the conveyor belt 4. The waste paper blocks will accumulate in the front part of the conveyor belt 4 when they roll down, which will result in the need to guide the accumulated waste paper blocks to ensure normal transportation work, which greatly reduces the work efficiency. In addition, there is no need to press and hold the waste paper blocks for transmission, which greatly reduces the transmission power and does not limit the size of the transmitted waste paper blocks.

[0033] Therefore, when the conveyor belt 4 starts to rotate, it drives the connected connecting plate 101, all parts of the fixed assembly and all parts of the scraper assembly to start rotating around the two transmission wheels 2. During the rotation, the limit plate 105 squeezes the extrusion block 103 above the limit plate 105, so that the extrusion block 103 moves upward, and the movement of the extrusion block 103 pushes the insertion block 104 to move upward. Figure 4 state, and at the same time, the squeezing block 103 compresses the first elastic member 102, so that the first elastic member 102 accumulates force, so that the insert block 104 can protrude from the upper surface of the conveyor belt 4, and when the waste paper block falls on the conveyor belt 4, the insert block 104 can be inserted into the bottom of the waste paper block to limit and fix the waste paper block, so that when the conveyor belt 4 drives the waste paper block to be transmitted to the waste paper recycling equipment, the waste paper block will not roll down, thereby avoiding the problem of waste paper block accumulation reducing the transmission efficiency;

[0034] Furthermore, because the waste paper block is made of various waste papers, many waste papers will be accompanied by liquids originally contained when they are recycled. A large part of these liquids are viscous, such as beverages and chemical reagents. Similarly, there will be viscous liquid in the waste paper block. At this time, if the insert block 104 is always protruding from the surface of the conveyor belt 4, and there are multiple insert blocks 104, the insert block 104 will be adhered to the viscous liquid when it is working, which will cause the insert block 104 to be adhered to the shredded paper. After the insert block 104 works for a long time, the shredded paper will The plug block 104 is agglomerated, which weakens the sharpness of the plug block 104, so that the plug block 104 can no longer be fixed to the waste paper block when it is inserted into the waste paper block. In addition, the sugar and chemical substances in the viscous liquid will corrode the plug block 104, further weakening the sharpness of the plug block 104. Therefore, when the plug block 104 rotates to the bottom of the limit plate 105, the squeeze block 103 no longer contacts the limit plate 105. At this time, the first elastic member 102 that has stored force begins to release the stored force, driving the connected squeeze block 103 to return to the Figure 5 In this process, the through groove of the connecting plate 101 penetrated by the plug block 104 can scrape off the shredded paper adhering to the surface of the plug block 104, thus avoiding the problem that the surface of the plug block 104 affects the operation of the device, and the plug block 104 under the limit plate 105 is retracted into the connecting plate 101, so that the lower surface of the conveyor belt 4 is smoother, and the external cleaning nozzle can clean the conveyor belt 4 more comprehensively;

[0035] Furthermore, when the plug block 104 is retracted into the connecting plate 101, the shredded paper adhering to the slanted surface of the plug block 104 cannot be cleaned because the slanted surface of the plug block 104 cannot be scraped by the through groove of the connecting plate 101. After the shredded paper on the slanted surface of the plug block 104 is retracted into the connecting plate 101, it is inevitable that the waste paper blocks are continuously transmitted and fall on the conveyor belt 4 during the operation of the device, and the parts of the device will vibrate. The shredded paper on the slanted surface of the plug block 104 retracted into the connecting plate 101 exists inside the device. If the plug block 104 shakes the shredded paper into the inside of the device, it will affect the normal operation of the device. Therefore, when the plug block 104 is retracted into the connecting plate 101, the shredded paper on the slanted surface of the plug block 104 is not removed. When the plug 104 extends out from the connecting plate 101, the inclined surface of the plug 104 will squeeze the scraper 202. At this time, the scraper 202 is forced to move, and the scraper 202 will stretch the second elastic member 203 during the movement, so that the second elastic member 203 has a reset elastic force. Afterwards, when the plug 104 is pulled and reset by the first elastic member 102, the scraper 202 is pulled and reset along the inclined surface of the plug 104 by the reset elastic force of the second elastic member 203. In this process, the shredded paper adhering to the inclined surface of the plug 104 can be cleaned to prevent it from falling into the interior of the device and affecting the normal operation of the device.

Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
