Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and more specifically, to a vibrating screen for papermaking. Background Technology

[0002] Papermaking is an industrial production technology and process that involves processing plant fibers (or other fiber raw materials) through a series of physical and chemical processes to ultimately produce sheet materials (i.e., paper) with specific performance characteristics (such as writing, printing, packaging, etc.). Its core is to separate and reorganize fibers to form sheet products with stable structure and usable function. Paper manufacturing typically involves raw material preparation, pulping, pulp purification and conditioning, and papermaking. During pulp purification, it may be difficult to accurately separate impurities such as fiber bundles, bark, dust, and metal fragments, leading to problems such as uneven paper thickness and excessive differences in strength. To address this, we provide a vibrating screen for papermaking. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a rotary vibration mechanism.

At this time, the connecting rod will rotate inside the extension plate. When the connecting rod rotates, the third gear will rotate. Because the outer surface of the third gear meshes with the tooth groove on the push rod, when the third gear rotates, it will push the push rod to move. At this time, the baffle plate will slide inside the collection frame, thereby collecting the sieved pulp that falls from the bottom into the collection frame. Its advantage is that the sieved pulp is collected, which facilitates subsequent processing. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 6As shown, this utility model provides a rotary vibrating screen for papermaking, including a support frame 11, a placement plate 12 fixedly connected to the top of the support frame 11, a tank 13 rotatably connected to the inner wall of the support frame 11, a rotary vibrating mechanism 1 provided at the bottom of the support frame 11, and a collection mechanism 2 provided at the bottom of the rotary vibrating mechanism 1. The vibrating mechanism 1 includes a motor 118. A drive shaft 101 is fixedly connected to the bottom output end of the motor 118 via a coupling. A crown gear 102 is fixedly connected to the bottom of the drive shaft 101. A bevel gear 103 is fixedly connected to the outer surface of the drive shaft 101. Several fixing blocks 108 are fixedly connected to the bottom of the placement plate 12. A rotating rod 105 is rotatably connected to the inner wall of each fixing block 108. A bevel gear 104 is fixedly connected to the outer wall of the rotating rod 105. A bevel gear 106 is fixedly connected to the end of the rotating rod 105 away from the bevel gear 104. A rotating rod 109 is rotatably connected to the inner wall of each fixing block 108. Gear 110 is fixedly connected to the outer wall. Push block 111 is fixedly connected to the end of rotating rod 109 away from gear 110. Extension frame 119 is fixedly connected to the bottom of placement plate 12. Center rod 112 is rotatably connected to the inner wall of extension frame 119. Bevel gear 4 107 is fixedly connected to the top of center rod 112. Gear 2 113 is fixedly connected to the end of center rod 112 away from bevel gear 4 107. External gear 114 is fixedly connected to the outer wall of tank body 13. Spring 115 is fixedly connected to the top of tank body 13. Vibration frame 116 is fixedly connected to the top of spring 115. Screen 117 is fixedly connected to the inner wall of vibration frame 116.

[0017] The motor 118 drives the transmission shaft 101 to rotate. When the transmission shaft 101 rotates, the crown gear 102 also rotates. At this time, the four gears 110 meshing with the crown gear 102 also rotate. When the gears 110 rotate, the rotating rod 109 fixed on its outer wall also rotates. At this time, the push block 111 also rotates. When the protruding part of the push block 111 contacts the vibrating frame 116, it will push it to tilt. At the same time, the spring 115 will also be compressed. While the motor 118 drives the transmission shaft 101 to rotate, the worker needs to put the pulp for papermaking into the surface of the screen 117. The screen 117 will rotate and vibrate on a small scale to shake and screen the pulp.

[0018] Among them, the bottom of the motor 118 is fixedly connected to the top of the placement plate 12, and the outer surface of the gear 110 meshes with the outer surface of the crown gear 102.

[0019] There are several gears 110, and the outer surface of bevel gear 104 meshes with the outer surface of bevel gear 103.

[0020] The outer surface of bevel gear 3 106 meshes with the outer surface of bevel gear 4 107, and the outer surface of gear 2 113 meshes with the outer surface of external gear 114.

[0021] The rotation of bevel gear 103 drives bevel gear 104 to rotate. When bevel gear 104 rotates, rotating rod 105 also rotates, and bevel gear 106 also rotates. When bevel gear 106 rotates, bevel gear 107 rotates, and central rod 112 rotates. When central rod 112 rotates, gear 113 rotates, thereby driving external gear 114 to rotate. At this time, tank 13 and the vibrating frame 116 on top of tank 13 also rotate, thus performing rotary screening of the pulp.

[0022] The collection mechanism 2 includes a collection frame 201, a baffle plate 202 slidably connected to the inner wall of the collection frame 201, a push rod 204 fixedly connected to the outer wall of the baffle plate 202, a plurality of toothed grooves 205 opened on the inner wall of the push rod 204, an extension plate 203 fixedly connected to the outer wall of the collection frame 201, a connecting rod 206 rotatably connected to the inner wall of the extension plate 203, a gear 207 fixedly connected to the top of the connecting rod 206, a worm gear 211 fixedly connected to the end of the gear 207 away from the connecting rod 206, a rotating frame 208 fixedly connected to the outer wall of the extension plate 203, a worm 209 rotatably connected to the inner wall of the rotating frame 208, and a handle 210 fixedly connected to the outer wall of the worm 209.

[0023] By rotating the handle 210, the worm 209 is driven to rotate inside the rotating frame 208. When the worm 209 rotates, the worm wheel 211 that meshes with it will rotate. At this time, the connecting rod 206 will rotate inside the extension plate 203. When the connecting rod 206 rotates, the gear 3 207 will rotate. Because the outer surface of the gear 3 207 meshes with the tooth groove 205 opened on the push rod 204, when the gear 3 207 rotates, it will push the push rod 204 to move. At this time, the baffle plate 202 will slide inside the collection frame 201, thereby collecting the sieved pulp that falls from the bottom of the tank 13 into the collection frame 201.

[0024] The outer wall of the collection frame 201 is fixedly connected to the outer wall of the support frame 11, and the outer wall of the push rod 204 penetrates the inner wall of the collection frame 201 and extends to the outside.

[0025] The outer surface of the connecting rod 206 is rotatably connected to the inner wall of the extension plate 203, and the outer surface of the gear 207 is meshed with the inner wall of the tooth groove 205.

[0026] When the push rod 204 moves, it drives the baffle plate 202 fixed on its outer wall to move. The top of the baffle plate 202 will block the opening at the bottom of the tank 13. When the baffle plate 202 moves, it will slowly open the opening of the tank 13, so that the pulp after screening inside falls into the collection frame 201.

[0027] Working principle and usage process of this utility model: The operator first starts the motor 118, which drives the transmission shaft 101 fixed at its bottom output end to rotate. When the transmission shaft 101 rotates, the crown gear 102 fixed at its bottom also rotates. At this time, the four gears 110 located at the bottom of the crown gear 102 and meshing with it also rotate. When the gears 110 rotate, the rotating rod 109 fixed on its outer wall also rotates. At this time, the push block 111 fixed at the end of the rotating rod 109 also rotates. When the protruding part of the push block 111 contacts the vibration frame 116, it pushes it to tilt. At the same time, the spring 115 located at the bottom of the vibration frame 116 is also compressed. When the motor 118 drives... As the drive shaft 101 rotates, the bevel gear 103 fixed to the outer surface of the drive shaft 101 rotates. At the same time, the bevel gear 104 meshing with the bevel gear 103 also rotates. When the bevel gear 104 rotates, the rotating rod 105 fixed to its outer wall also rotates. At the same time, the bevel gear 106 fixed to the outer wall of the rotating rod 105 also rotates. When the bevel gear 106 rotates, the bevel gear 107 meshing with it rotates. At the same time, the center rod 112 fixed at the bottom of the bevel gear 107 rotates. When the center rod 112 rotates, the gear 113 fixed at its bottom rotates, thereby driving the gear 107... The external gear 114, which meshes with the outer surface of the external gear 114, rotates. At this time, the tank 13 fixed on the inner wall of the external gear 114 and the vibrating frame 116 on the top of the tank 13 also rotate. The worker needs to put the pulp for papermaking into the surface of the screen 117. The screen 117 will rotate and vibrate on a small scale. The advantage of this is that the pulp is screened more finely, which improves the quality of the finished paper and also improves the efficiency of subsequent processes. After the pulp is screened, it needs to be collected. Turning the handle 210 drives the worm 209 fixed on its outer wall to rotate inside the rotating frame 208. When the worm 209 rotates, the worm wheel meshing with it on its outer surface... 211 will rotate, and the connecting rod 206 fixed at the top of the worm gear 211 will rotate inside the extension plate 203. When the connecting rod 206 rotates, the gear 3 207 fixed at its top will rotate. Since the outer surface of the gear 3 207 meshes with the tooth groove 205 opened on the push rod 204, when the gear 3 207 rotates, it will push the push rod 204 to move. At this time, the baffle plate 202 fixed on the outer wall of the push rod 204 will slide inside the collection frame 201, thereby collecting the sieved pulp that falls from the bottom of the tank 13 into the collection frame 201. The advantage of this is that the sieved pulp is collected, which facilitates subsequent processing.
