Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing technology, and in particular to an auxiliary feeding device for the production of plastic flange covers. Background Technology
[0002] Plastic flanges have the following performance characteristics: lightweight, as plastic is a relatively light material; excellent chemical stability, as most plastics have good resistance to corrosion from acids, alkalis, and other chemicals; and excellent electrical insulation properties, as ordinary plastics are poor conductors of electricity, with high surface and volume resistivity. Plastic flange production is generally completed through injection molding. Before injection molding, the plastic raw materials need to be mixed and melted. Workers often have to carry a bag of mixture up to a high mixing machine, then lift the bag of mixture and pour it into the mixing machine for mixing. This not only requires a lot of physical strength but is also highly dangerous.
[0003] For example, a feeding device for producing modified plastic granules disclosed in Chinese patent literature (publication number: CN217943885U) saves labor and avoids danger by raising the feeding box containing the mixture and then letting the mixture fall from the feeding box into the mixing machine; the screw carries the screw block and the feeding box to rise and fall; the vertical plate not only blocks the discharge hole but also serves as a fixing block; when the feeding box rises to the top, the discharge hole connects with the through hole, allowing the mixture to fall from the feeding box into the mixing machine; the downward-sloping discharge pipe brings the pipe opening close to the mixing cylinder, making the discharge easier to control; the bottom surface of the feeding box is inclined from all sides towards the discharge hole, allowing the mixture to roll down into the discharge hole and preventing the mixture from remaining in the feeding box; the rear end face of the feeding box is flush with the rear end face of the screw block, allowing the screw block to also fit against the vertical plate.
[0004] However, because the position of the feeding pipe is fixed and cannot be flexibly adjusted, the entire feeding process must strictly adhere to the condition that the feeding box rises to a specific height in order for the material to be smoothly discharged from the feeding pipe. This makes it unusable when dealing with mixers of different specifications and heights. Furthermore, if there is a large height difference between the feeding pipe and the mixer's inlet, due to the light weight of the plastic granules, they are easily scattered and spilled from the gap between the feeding pipe and the inlet during the discharge process due to the combined effects of their own weight, discharge force, and surrounding airflow, resulting in waste. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as limited height during material feeding, low applicability, and the tendency for materials to spill and cause waste.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An auxiliary feeding device for the production of plastic flange covers includes a counterweight base. The counterweight base is provided with a moving adjustment mechanism, which includes lead screws. One end of two lead screws is symmetrically distributed and rotatably connected to the inner bottom wall of the counterweight base through bearings. A worm gear is fixedly sleeved on the outside of the lead screws.
[0008] The other end of the lead screw passes through and extends to the upper end of the counterweight base. The other ends of both lead screws are rotatably connected to fixed brackets via bearings. Both ends of the fixed brackets are fixedly connected to the upper end of the counterweight base. A servo motor is fixedly installed on the front of the counterweight base. A worm gear is fixedly installed on the output shaft of the servo motor via a coupling. One end of the worm gear passes through and extends into the interior of the counterweight base. The other end of the worm gear is rotatably connected to the rear inner wall of the counterweight base via a bearing.
[0009] Preferably, the lead screw is externally threaded with a threaded block, and an L-shaped lifting plate is fixedly connected to one side of each of the two threaded blocks. The upper end of the L-shaped lifting plate is provided with a through groove.
[0010] Preferably, the upper end of the L-shaped lifting plate is fixedly connected to symmetrically distributed guide rails, the outside of the guide rails is slidably connected to a movable sleeve, and the upper end of the movable sleeve is fixedly connected to a fixing block.
[0011] Preferably, a material cylinder is fixedly connected to one end of each of the two fixed blocks, and a servo electric cylinder is fixedly installed on the inner wall of one side of the L-shaped lifting block, with one end of the piston rod of the servo electric cylinder fixedly connected to the outside of the material cylinder.
[0012] Preferably, the bottom of the material cylinder is fixedly connected to an inclined discharge pipe, and an electromagnetic valve is provided on the outside of the inclined discharge pipe. One end of the inclined discharge pipe passes through the through groove and extends to the bottom of the L-shaped lifting plate.
[0013] Preferably, a high-definition camera is fixedly installed on the outside of one end of the inclined discharge pipe, and self-locking universal wheels arranged in a rectangular array are fixedly installed on the lower end of the counterweight base.
[0014] Preferably, a push frame is fixedly connected to the upper end of the counterweight base, and a display screen is fixedly installed on the upper end of the push frame.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In this invention, the movable adjustment mechanism enables the adjustment of the material cylinder to discharge at different heights. Furthermore, with the assistance of a high-definition camera, it facilitates the movement of the inclined discharge pipe at the lower end of the material cylinder to the feeding port for precise feeding, thereby avoiding waste caused by material spillage during the feeding process. This not only improves the workshop working environment but also reduces production costs. Attached Figure Description

[0026] Example
[0027] like Figures 1-4 As shown, this utility model provides a technical solution: an auxiliary feeding device for the production of plastic flange covers, including a counterweight base 1. The upper end of the counterweight base 1 is equipped with a high-density lead block or other counterweight material, providing excellent stability. Even during frequent lifting and moving of the material cylinder 211, it can stand firmly on the workshop floor, effectively preventing tipping due to instability and ensuring the safe and orderly operation of the feeding process. The counterweight base 1 has an internal moving adjustment mechanism, which includes lead screws 2. The lead screws 2 are made of high-strength alloy steel, possessing excellent rigidity and wear resistance, and can withstand long-term, high-intensity operation. One end of each lead screw 2 is... The screw 2 is symmetrically distributed and rotatably connected to the inner bottom wall of the counterweight base 1 via high-precision bearings. These bearings are deep groove ball bearings, with a model that matches the size of the lead screw 2. The inner ring fits tightly with the lead screw 2, and the outer ring is firmly embedded in the mounting hole in the inner bottom wall of the counterweight base 1, ensuring smooth rotation and high concentricity of the lead screw 2. A worm gear 21 is fixedly sleeved on the outside of the lead screw 2. The worm gear 21 is made of copper alloy, which is tough and has good wear resistance and self-lubricating properties. When meshing with the worm 24, it can effectively reduce the coefficient of friction, reduce energy loss, and ensure transmission efficiency. Its tooth profile is precision machined and has a very high degree of fit with the tooth surface of the worm 24, making the power transmission accurate and stable.
[0028] The other end of the lead screw 2 passes through and extends to the upper end of the counterweight base 1. A sealing ring is installed at the through-hole to prevent dust and debris from entering the counterweight base 1 and affecting the operation of the lead screw 2 and other components. The other ends of both lead screws 2 are rotatably connected to fixed brackets 22 via bearings. The fixed brackets 22 are welded from sturdy carbon steel, and both ends are welded and fixed to the upper end of the counterweight base 1 to provide stable support for the upper end of the lead screw 2, ensuring that the lead screw 2 does not deviate or shake during rotation. A servo motor 23 is fixedly installed on the front of the counterweight base 1. The servo motor 23 can be controlled by the control cabinet. The servo motor 23 can be remotely and conveniently controlled via an operation panel. The output shaft of the servo motor 23 is fixedly mounted with a worm gear 24 through a flexible coupling. The flexible coupling can effectively buffer the impact generated when the servo motor 23 starts and stops, protect the worm gear 24 and the output shaft of the servo motor 23, and extend the service life of the equipment. The worm gear 24 is also made of high-strength alloy steel with surface quenching treatment, resulting in high hardness and strong wear resistance. One end of the worm gear 24 passes through and extends into the interior of the counterweight base 1. One end of the worm gear 24 is rotatably connected to the rear inner wall of the counterweight base 1 through a bearing, ensuring that the worm gear 24 rotates smoothly within the counterweight base 1.
[0029] The lead screw 2 is externally threaded with a threaded block 25. When the lead screw 2 rotates, the threaded block 25 can move quickly and accurately in a straight line along the lead screw 2, and the operation is smooth without jamming or loosening. An L-shaped lifting plate 26 is fixedly connected to one side of each of the two threaded blocks 25. The L-shaped lifting plate 26 is injection molded from high-strength engineering plastic, which has the advantages of being lightweight and corrosion-resistant, and at the same time has sufficient strength to support the weight of the material cylinder 211 and the material. A through groove 27 is opened at the upper end of the L-shaped lifting plate 26. The length of the through groove 27 is reasonably determined according to the range of motion of the inclined discharge pipe 213, so as to ensure that the inclined discharge pipe 213 can pass through smoothly and move freely.
[0030] The upper end of the L-shaped lifting plate 26 is fixedly connected to symmetrically distributed guide rails 28. The guide rails 28 are made of stainless steel with a polished surface to reduce friction with the moving sleeve 29, providing a solid guarantee for the smooth movement of the material cylinder 211. The moving sleeve 29 is slidably connected to the outside of the guide rails 28. The moving sleeve 29 is made of aluminum alloy, which can ensure that the moving sleeve 29 slides smoothly on the guide rails 28 and transmit stable force during the movement of the material cylinder 211, without shaking or loosening. The upper end of the moving sleeve 29 is fixedly connected to a fixing block 210. The fixing block 210 and the moving sleeve 29 are connected by welding. The welded parts are inspected for flaws to ensure a firm connection, providing stable support for the subsequent installation of the material cylinder 211.
[0031] Both fixed blocks 210 have a material cylinder 211 fixedly connected to one end. The material cylinder 211 is made of food-grade stainless steel with a smooth inner wall, which facilitates smooth material flow, prevents residue accumulation, and is resistant to acid and alkali corrosion. It can adapt to the characteristics of various plastic raw materials. The capacity of the material cylinder 211 is precisely designed according to the production process requirements. The cylinder body is marked with scale lines, which makes it convenient for operators to intuitively understand the material inventory. A servo electric cylinder 212 is fixedly installed on one inner wall of the L-shaped lifting block. The servo electric cylinder 212 is a high-precision, high-thrust electric cylinder. The stroke is set according to the horizontal fine adjustment requirements of the material cylinder 211. It has the ability to respond quickly and position accurately. One end of its piston rod is fixedly connected to the outside of the material cylinder 211. The connection method adopts a detachable flange connection, which is convenient for maintenance and replacement.
[0032] The bottom of the material cylinder 211 is fixedly connected to an inclined discharge pipe 213. The inclined discharge pipe 213 is made of stainless steel of the same material as the material cylinder 211. The pipe diameter is reasonably selected according to the material flowability and discharge speed requirements. The pipe body is inclined at a certain angle to ensure that the material can flow out naturally and smoothly under the action of gravity. An electromagnetic valve 214 is installed on the outside of the inclined discharge pipe 213. The electromagnetic valve 214 is a wear-resistant and fast-response two-position two-way electromagnetic valve, which can accurately control the opening and closing of the discharge pipe. Its opening and closing status can be remotely monitored and operated through the operation panel or the automatic control system. One end of the inclined discharge pipe 213 passes through the through groove 27 and extends to the bottom of the L-shaped lifting plate 26.
[0033] A high-definition camera 215 is fixedly installed on one end of the inclined discharge pipe 213. The high-definition camera 215 adopts an industrial-grade high-definition lens, which has high resolution and low light performance. It can clearly capture the scene around the feeding port in the complex lighting environment of the workshop. Its installation angle can be finely adjusted to ensure the best shooting field of view. The camera is connected to the display screen 218 through a waterproof and anti-interference cable to transmit stable and clear image signals in real time. The lower end of the counterweight base 1 is fixedly installed with self-locking casters 216 arranged in a rectangular array. The self-locking casters 216 are industrial casters with strong load-bearing capacity and flexible steering. Each wheel has an independent braking device, which facilitates the rapid movement and positioning of the equipment in the workshop. After moving to the designated position, it can be quickly locked to ensure the stability of the equipment during the feeding operation.
[0034] The upper end of the counterweight base 1 is fixedly connected to the push frame 217. The push frame 217 is made of aluminum alloy, which is lightweight and sturdy, making it easy for operators to hold and push the equipment. The upper end of the push frame 217 is fixedly installed with a display screen 218. The display screen 218 is an industrial-grade touch screen with a moderate size and clear display. It has multiple functions such as image display, equipment status monitoring, and operation command input. Operators can intuitively understand the position of the material cylinder 211 and the connection between the discharge pipe and the feeding port through the display screen 218, and conveniently control the entire feeding process.
[0035] The working process of this utility model:
[0036] Step 1: When feeding is required, first start the servo motor 23 on the front of the counterweight base 1. The output shaft of the servo motor 23 rotates, driving the worm 24 connected to it via a coupling to rotate synchronously. Since the worm 24 meshes with the worm wheels 21 fixedly sleeved on the outside of the two lead screws 2, the two worm wheels 21 drive the corresponding lead screws 2 to start rotating under the drive of the worm 24. The lead screws 2 are rotatably connected to the inner bottom wall of the counterweight base 1 and the fixed bracket 22 through bearings, ensuring smooth and stable rotation. As the lead screws 2 rotate, the threaded blocks 25 connected to their external threads will move linearly along the lead screws 2. Since L-shaped lifting plates are fixedly connected to one side of each of the two threaded blocks 25, the L-shaped lifting plates will rise accordingly, realizing the height adjustment function to meet the feeding needs of feeding ports of different heights.
[0037] Step 2: During the lifting process, the guide rail 28 fixedly connected to the upper end of the L-shaped lifting plate cooperates with the moving sleeve 29. The moving sleeve 29 can slide along the guide rail 28, ensuring the stability of the material cylinder 211 fixed to one end of the fixed block 210 at the upper end of the moving sleeve 29 when moving in the vertical direction, and preventing the material cylinder 211 from shaking and causing the material to spill out. When the material cylinder 211 reaches a roughly suitable height position, if it is necessary to make a fine adjustment to the horizontal position of the material cylinder 211, the servo electric cylinder 212 fixedly installed on the inner wall of one side of the L-shaped lifting block can be activated. The piston rod of the servo electric cylinder 212 extends and retracts, pushing or pulling the material cylinder 211 to move in the horizontal direction, accurately positioning the relative position of the material cylinder 211 and the feeding port. The inclined discharge pipe 213 fixedly connected to the bottom of the material cylinder 211 is used for material output.
[0038] Step 3: Before discharging, a high-definition camera 215 fixedly installed on one end of the inclined discharge pipe 213 transmits the image around the feeding port in real time to a display screen 218 fixedly installed on the push frame 217 at the top of the counterweight base 1. The operator can accurately judge the distance and angle deviation between the inclined discharge pipe 213 and the feeding port based on the image information fed back by the display screen 218. Then, fine adjustments are made again through the moving adjustment mechanism and the servo electric cylinder 212 until the inclined discharge pipe 213 is accurately aligned with the feeding port. After preparation, the solenoid valve 214 set on the outside of the inclined discharge pipe 213 is opened, and the material flows smoothly into the feeding port along the inclined discharge pipe 213. Due to the precise feeding control, the material spillage caused by the misalignment of the discharge pipe and the feeding port during the feeding process is effectively avoided, reducing material waste, maintaining workshop cleanliness, improving the quality of the workshop working environment, and reducing the increase in production costs caused by material loss. This ensures efficient and precise operation of the feeding process in the production of plastic flange covers.
