Description

Technical Field

[0001] This application relates to the field of side feeder technology, and more particularly to a leak-proof feed hopper for a side feeder. Background Technology

[0002] Side feeders are widely used in the plastics processing industry to add raw materials to processing equipment evenly and stably. However, existing side feeders have a certain problem of raw material leakage during the feeding process, which not only wastes raw materials but may also affect the cleanliness of the production environment and production efficiency.

[0003] Currently, some side feeders on the market use gates made of elastic materials to control the feeding. However, after long-term use, the elastic materials are prone to aging, resulting in a decrease in sealing performance and leakage of raw materials. Another common solution is to set an adjustable baffle at the outlet of the hopper, but the operation is complicated and the effect is limited.

[0004] Therefore, this application proposes a leak-proof feed hopper for a side feeder. Utility Model Content

[0005] The leak-proof feed hopper of the side feeder proposed in this application solves the problems mentioned in the background art. The leak-proof feed hopper of the side feeder improves the sealing performance at the connection between the upper and lower connecting parts by setting a sealing mechanism, a sealing ring, an adjusting ring, a threaded hole, a bolt, and a button. The sealing ring is placed outside the ring groove, and then the adjusting ring is placed outside the sealing ring. Turning the button can drive the bolt to rotate, tightening the adjusting ring and applying pressure to the sealing ring to form a sealing state. It can be adjusted arbitrarily according to the sealing requirements of different materials. This mechanism avoids the problem of raw material leakage during the feeding process of the feeder. Moreover, the mechanism has a simple structure, is easy to operate, and greatly improves the practicality of the device.

[0006] To achieve the above objectives, this application adopts the following technical solution: The leak-proof feed hopper of the side feeder includes a hopper body. The top of the hopper body is provided with a feeding structure, and the inside of the feeding structure is provided with a venting structure. The bottom of the hopper body is provided with a connecting structure, and the outside of the connecting structure is provided with a sealing mechanism. The sealing mechanism includes a sealing ring, which is slidably connected to the outside of the connecting structure. An adjusting ring is slidably connected to the outside of the sealing ring. A threaded hole is opened on one side surface of the adjusting ring. A bolt is threadedly connected to the inside of the threaded hole, and the bolt passes through the threaded hole. A button block is fixedly connected to the front end of the bolt.

[0007] In a preferred embodiment, the feeding structure includes a top plate, which is fixedly connected to the top of the hopper body. A leak-proof plate is fixedly connected to the top of the top plate, and a feeding port is installed on the middle surface of the top plate. By adding raw materials into the hopper body through 23, the anti-leakage plate can prevent the raw materials from falling outside the device and causing waste, thereby improving the practicality of the device.

[0008] In a preferred embodiment, a heating plate is installed on the inner wall of the hopper body; The raw materials may be in a damp state before processing. The heating plate can heat and dry the raw materials, thereby improving the practicality of the device.

[0009] In a preferred embodiment, mounting grooves are provided on both sides of the top plate, and an exhaust plate is fixedly connected inside the mounting grooves; The raw materials are dried inside the hopper body, which generates a large amount of water vapor. As the raw materials move downward, the water vapor is subjected to forces from both above and below, creating pressure inside the hopper body. The water vapor can be filtered and discharged through the exhaust plate, thereby improving the practicality of the device.

[0010] In a preferred embodiment, the connection structure includes an upper connector, which is fixedly connected to the bottom of the hopper body. A lower connector is installed on the top of the feeder, and the upper connector and the lower connector are spliced ​​together. Both the upper connector and the lower connector have annular grooves on their surfaces. By splicing the upper and lower connectors, the hopper body is connected to the feeder, ensuring that the raw materials can smoothly enter the feeder through the hopper body, forming a complete structure and thus improving the practicality of the device.

[0011] In a preferred embodiment, the cross-sectional area of ​​the hopper body gradually decreases from top to bottom; By designing the cross-section of the hopper body to be larger at the top and smaller at the bottom, the amount of raw material entering the feeder can be reduced, effectively preventing blockage of the feeder and thus improving the practicality of the device.

[0012] In a preferred embodiment, the sealing ring is manufactured with a wear-resistant material, and the material is ultra-high molecular weight polyethylene. By adding ultra-high molecular weight polyethylene into the sealing ring, its surface wear resistance can be greatly improved, the service life of the sealing ring can be increased, and thus the practicality of the device can be enhanced.

[0013] The beneficial effects of this application are: 1. The leak-proof feed hopper of this side feeder improves the sealing performance at the connection between the upper and lower connecting parts by setting a sealing mechanism, sealing ring, adjusting ring, threaded hole, bolt and button. The sealing ring is placed on the outside of the ring groove, and the adjusting ring is placed on the outside of the sealing ring. Turning the button can drive the bolt to rotate, tighten the adjusting ring, apply pressure to the sealing ring, and form a seal. It can be adjusted arbitrarily according to the sealing requirements of different materials. This mechanism avoids the problem of raw material leakage during the feeding process of the feeder. Moreover, the mechanism has a simple structure and is easy to operate, which greatly improves the practicality of the device. 2. The leak-proof feed hopper of this side feeder can release the pressure formed inside the hopper body by setting an exhaust structure, mounting groove and exhaust plate. When the raw material enters the hopper body for drying, a large amount of water vapor will be generated. As the raw material moves downward, the water vapor is subjected to vertical force, which creates pressure inside the hopper body. The water vapor can be filtered and discharged through the exhaust plate, which greatly improves the practicality of the device. Attached Figure Description

[0016] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0017] Reference Figures 1-2The side feeder's leak-proof feeding hopper includes a hopper body 1. A feeding structure 2 is provided on the top of the hopper body 1. The feeding structure 2 includes a top plate 21, which is fixedly connected to the top of the hopper body 1. A leak-proof plate 22 is fixedly connected to the top of the top plate 21, and a feeding port 23 is installed on the middle surface of the top plate 21. Raw materials are added to the inside of the hopper body 1 through the 23. With the help of the leak-proof plate 22, the raw materials can be prevented from falling outside the device and wasting the materials, thereby improving the practicality of the device.

[0018] Reference Figure 3 A heating plate 11 is installed on the inner wall of the hopper body 1. The raw material may be in a damp state before processing. The heating plate 11 can heat and dry the raw material, thereby improving the practicality of the device.

[0019] Reference Figures 1-2 The feeding structure 2 is equipped with an exhaust structure 3 inside. The top plate 21 has mounting grooves 31 on both sides. An exhaust plate 32 is fixedly connected inside the mounting grooves 31. When the raw material enters the hopper body 1 for drying, a large amount of water vapor will be generated. As the raw material moves downward, the water vapor is subjected to vertical force, which creates pressure inside the hopper body 1. The water vapor can be filtered and discharged through the exhaust plate 32, thereby improving the practicality of the device.

[0020] Reference Figure 1 , 3 4. A connecting structure 4 is provided at the bottom of the hopper body 1. The connecting structure 4 includes an upper connecting member 41, which is fixedly connected to the bottom of the hopper body 1. A lower connecting member 43 is installed on the top of the feeder, and the upper connecting member 41 and the lower connecting member 43 are spliced ​​together. Both the upper connecting member 41 and the lower connecting member 43 have annular grooves 42 on their surfaces. By splicing the upper connecting member 41 and the lower connecting member 43, the hopper body 1 is connected to the feeder, ensuring that the raw material can smoothly enter the feeder through the hopper body 1, forming a complete structure, thereby improving the practicality of the device.

[0021] Reference Figures 1-2 A sealing mechanism 5 is provided on the outside of the connecting structure 4. The sealing mechanism 5 includes a sealing ring 51, and the sealing ring 51 is slidably connected to the outside of the ring groove 42. An adjusting ring 52 is slidably connected to the outside of the sealing ring 51. A threaded hole 53 is opened on one side surface of the adjusting ring 52. A bolt 54 is threaded inside the threaded hole 53 and passes through the threaded hole 53. A button block 55 is fixedly connected to the front end of the bolt 54. The sealing ring is placed outside the ring groove, and then the adjusting ring is placed outside the sealing ring. Turning the button will drive the bolt to rotate, tightening the adjusting ring and applying pressure to the sealing ring to form a seal. The mechanism can be adjusted arbitrarily according to the sealing requirements of different materials. This mechanism avoids the problem of raw material leakage during the feeding process of the feeder. Moreover, the mechanism has a simple structure and is easy to operate, which greatly improves the practicality of the device.

[0022] Reference Figures 1-3 The cross-sectional area of ​​the hopper body 1 gradually decreases from top to bottom. By setting the cross-section of the hopper body 1 to be larger at the top and smaller at the bottom, the amount of raw material entering the feeder can be reduced, effectively preventing the feeder from getting clogged, thereby improving the practicality of the device.

[0023] Reference Figures 1-2 Wear-resistant material, specifically ultra-high molecular weight polyethylene, is added during the manufacturing of the sealing ring 51. By adding ultra-high molecular weight polyethylene into the sealing ring 51, its surface wear resistance can be greatly improved, thereby increasing the service life of the sealing ring 51 and enhancing the practicality of the device.

[0024] Working principle: Before using the device, the sealing ring 51 is placed on the outside of the ring groove 42, and then the adjusting ring 52 is placed on the outside of the sealing ring 51. Turning the button block 55 will drive the bolt 54 to rotate, tightening the adjusting ring 52 and applying pressure to the sealing ring 51 to form a seal. The adjustment can be made arbitrarily according to the sealing requirements of different materials. Adding ultra-high molecular weight polyethylene inside the sealing ring 51 can greatly improve its surface wear resistance and extend the service life of the sealing ring 51. During use, raw materials are added to the inside of the hopper body 1 via 23. The anti-leakage plate 22 can prevent raw materials from falling outside the device and causing waste. The raw materials may be in a damp state before processing. The heating plate 11 can heat and dry the raw materials to achieve a drying effect. When the raw materials enter the hopper body 1 for drying, a large amount of water vapor will be generated. As the raw materials move downward, the water vapor is subjected to vertical forces, which creates pressure inside the hopper body 1. The water vapor can be filtered and discharged through the exhaust plate 32. The cross-section of the hopper body 1 is set to be larger at the top and smaller at the bottom, which can reduce the amount of raw materials entering the feeder and effectively prevent the feeder from clogging.
