Flange labor-saving slide table inclined hopper automatic discharging device

Abstract

This utility model discloses an automatic unloading device for flanges using a sliding table and inclined hopper, including a drive sliding assembly. The drive sliding assembly includes a sliding table body, and a detachable placement frame is provided on the top of the sliding table body. The inclined hopper of this utility model adopts a composite structure of a stainless steel outer layer and a high-density polyethylene inner layer. The stainless steel outer layer ensures load-bearing strength, while the high-density polyethylene inner layer provides a cushioning effect and excellent toughness. When the flange slides from the sliding table into the inclined hopper, the inner layer absorbs the impact force through elastic deformation, preventing edge collisions caused by direct contact between the flange and metal. Rubber buffer plates are installed on the support blocks on the front and back of the inclined hopper via a rotating shaft. When the flange slides down, it first contacts the rubber buffer plate. The buffer plate rotates around the rotating shaft, converting the hard impact into rolling friction, while simultaneously compressing the buffer spring at the bottom of the stabilizing block, further absorbing the remaining impact force and completely preventing scratches on the sealing surface, allowing it to fall stably onto the lower conveyor belt.

Description

Technical Field

[0001] This utility model relates to the field of flange feeding technology, and in particular to an automatic flange feeding device with a sliding table and inclined bucket. Background Technology

[0002] Flanges, as core components for pipe connections and equipment docking, are widely used in petrochemical, municipal engineering, and machinery manufacturing industries. In mass production, after the flange's outer diameter and end face are machined on a lathe or bolt holes are machined on a drilling machine, it needs to be transferred from the worktable of the processing equipment to a turnover material frame or the next workstation. This process is called unloading.

[0003] In the prior art, such as Chinese Patent Publication No. CN118458317A, a flange processing unloading device is disclosed, including a conveyor seat, a conveyor belt is provided inside the conveyor seat, a concave seat is provided between the upper parts of the two sides of the conveyor seat, and grooves are provided on both sides of the inside of the conveyor seat at the upper position of the conveyor belt. A limit plate is rotatably hinged inside the groove, the bottom of the limit plate contacts the upper part of the conveyor belt, and the end of the limit plate away from its hinge point extends out of the inside of the groove.

[0004] The existing solutions described above only provide simple conveying, resulting in a lack of buffering at the end of the conveyor belt. Flanges fall directly from the conveyor belt to the next conveyor belt or into the material frame, making the flange edges prone to impact and deformation. Furthermore, the existing conveyor belt height is typically fixed at 800mm, while the processing equipment's worktable height is usually 1000-1100mm. Workers must bend over to move the flanges from the worktable to the conveyor belt, increasing labor costs. Therefore, we provide a labor-saving automatic flange feeding device with a sliding table and inclined bucket. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an automatic flange feeding device with a sliding table and inclined bucket, which provides a buffering effect during flange feeding and reduces damage.

[0006] An automatic feeding device for flange-type labor-saving sliding table and inclined bucket according to an embodiment of the present utility model includes: A drive sliding assembly includes a slide body, a detachable placement frame is provided on the top of the slide body, and an installation block is provided on the left side of the placement frame; The feeding buffer assembly includes an inclined bucket body, which is located on the right side of the slide body. The inclined bucket body is composed of a stainless steel outer layer and a high-density polyethylene inner layer, and the high-density polyethylene inner layer is fixed to the inner wall of the stainless steel outer layer by bolts.

[0007] According to some embodiments of the present invention, a fixing block is installed on the left side of the slide body, and a first electric push rod is installed on the right side of the fixing block, with the right end of the first electric push rod fixedly connected to the left side of the mounting block.

[0008] According to some embodiments of the present invention, a slot is provided on the right side of the front of the mounting block, and an insert is installed on the left side of the placement frame at the position corresponding to the slot. The left side of the insert penetrates the slot and extends into it to contact the inner wall of the slot. A fastening bolt that is threadedly connected to the insert is provided at the bottom of the left side of the mounting block.

[0009] According to some embodiments of this utility model, the front and right sides of the placement frame are both open, and two second electric push rods are installed on the top of the placement frame. The output ends of the two second electric push rods are fixedly connected by a limiting baffle.

[0010] According to some embodiments of the present invention, a positioning block is installed at the bottom of the limiting baffle, a positioning groove is provided at the top of the placement frame corresponding to the position of the positioning block, and the bottom of the positioning block passes through the positioning groove and extends into it to contact the inner wall of the positioning groove.

[0011] According to some embodiments of the present invention, support blocks are installed on both the front and back sides of the inclined bucket body, and a rotating shaft is rotatably connected to the grooves on opposite sides of the two support blocks via bearings, and a rubber buffer plate is installed on the surface of the rotating shaft.

[0012] According to some embodiments of the present invention, stabilizing blocks are installed at the bottom of both the front and back sides of the inclined bucket body, and the bottom of the stabilizing blocks is connected to the top of the rubber buffer plate by a buffer spring.

[0013] According to some embodiments of this utility model, the left side and bottom of the inclined bucket body are both open, and the inclined bucket body is fixedly connected to the slide body by bolts.

[0014] The present invention has the following beneficial effects: 1. This utility model's inclined bucket adopts a composite structure of a stainless steel outer layer and a high-density polyethylene inner layer. The stainless steel outer layer ensures load-bearing strength, while the high-density polyethylene inner layer provides a cushioning effect and excellent toughness. When the flange slides from the slide table into the inclined bucket, the inner layer absorbs the impact force through elastic deformation, avoiding edge collisions caused by direct contact between the flange and metal. The support blocks on the front and back of the inclined bucket are equipped with rubber buffer plates through a rotating shaft. When the flange slides down, it first contacts the rubber buffer plate. The buffer plate rotates around the rotating shaft, converting the hard impact into rolling friction. At the same time, it compresses the buffer spring at the bottom of the stabilizing block, further absorbing the remaining impact force and completely avoiding scratches on the sealing surface, allowing it to fall stably onto the lower conveyor belt.

[0015] 2. The slide body of this utility model is set with a 20° tilt angle, and the gravity component of the flange is used to assist in the conveying. Compared with horizontal conveying, the driving force requirement of the first electric push rod is reduced, which saves energy and avoids overload damage to the push rod. At the same time, the tilt direction is aligned with the inlet of the inclined bucket, and the flange can be quickly slid into the inclined bucket. The flange can be directly placed into the placement frame from the processing equipment without the need for workers to bend over and carry it, further reducing labor costs.

[0023] Please see Figure 1-5An automatic flange feeding device with a sliding table and inclined bucket includes a drive sliding assembly 1. The drive sliding assembly 1 includes a sliding table body 11, which supports a placement frame 12 and a flange, and provides guidance for the movement of the placement frame 12. It has a 20° tilt angle and utilizes the gravity component of the flange for auxiliary conveying, reducing the drive load. The tilt design reduces the driving force requirement of the first electric push rod 15; for example, conveying a 15kg flange requires only 80N of thrust, saving energy and avoiding push rod overload. The sliding table body 11 is made of Q235 steel plate. A detachable placement frame 12 is provided on the top of the sliding table body 11. The bottom of the placement frame 12 slides in contact with the top of the sliding table body 11. The placement frame 12 is used to accommodate and limit the flange and is made of 304 stainless steel plate. A mounting block 13 is provided on the left side of the placement frame 12. The right side of the mounting block 13 contacts the left side of the placement frame 12. The left side of the mounting block 13 contacts the first electric push rod 15. The push rod 15 is fixed, and the right side is connected to the placement frame 12 through the insert block 17 and slot 16 to transmit the driving force of the push rod. Support legs are installed at the four corners of the bottom of the slide body 11. A controller is installed at the bottom of the slide body 11. The first electric push rod 15 and the second electric push rod 19 are electrically connected to the controller and powered by an external power source. A fixing block 14 is installed on the left side of the slide body 11. The fixing block 14 is fixedly connected to the slide body 11 by welding to provide a stable mounting carrier for the first electric push rod 15. The first electric push rod 15 is installed on the right side of the fixing block 14. The first electric push rod 15 outputs linear thrust, pushing the mounting block 13 and the placement frame 12 to move along the slide body 11 towards the inclined bucket. It is electrically connected to the controller to realize the automatic cycle of extension, pushing and retraction without manual intervention. The thrust is adjustable from 500-1000N and the speed is controllable from 0.2-0.3m / s, suitable for flanges of different weights (5-50kg), uniform speed conveying without impact, with self-locking function, can stay stably after being pushed into place, preventing the flange from retracting before sliding into the inclined bucket. The right end of the first electric push rod 15 is fixedly connected to the left side of the mounting block 13. A slot 16 is opened on the right side of the front of the mounting block 13. An insert 17 is installed on the left side of the placement frame 12, corresponding to the position of the slot 16. The left side of the insert 17 passes through the slot 16 and extends into it, contacting the inner wall of the slot 16. Both the slot 16 and the insert 17 are trapezoidal in shape, ensuring... To ensure stability during vertical and horizontal connections, the front-to-back direction is locked using fastening bolts 18, guaranteeing stability when the insert 17 is connected to the slot 16. A fastening bolt 18, threaded to the insert 17, is located at the bottom left side of the mounting block 13. The placement frame 12 is connected to the mounting block 13 via the insert 17, slot 16, and fastening bolts 18. To disassemble and maintain the placement frame 12, simply unscrew the fastening bolts 18 and pull the insert 17 of the placement frame 12 out of the slot 16 of the mounting block 13. The front and right sides of the placement frame 12 are... In the open state, two second electric push rods 19 are installed on the top of the placement frame 12. The two second electric push rods 19 synchronously drive the limiting baffle 110 to move up and down. The output ends of the two second electric push rods 19 are fixedly connected through the limiting baffle 110. The side of the limiting baffle 110 closest to the placement frame 12 is in sliding contact with the placement frame 12. The limiting baffle 110 is used to seal the opening on the right side of the placement frame 12 to prevent the flange from being placed inside the placement frame 12 and sliding out of the placement frame 12 due to tilting. The limiting baffle 110 is made of 304 stainless steel. Made of stainless steel plate, the limiting baffle 110 has a positioning block 111 installed at its bottom. A positioning groove 112 is formed at the top of the placement frame 12 corresponding to the position of the positioning block 111. The bottom of the positioning block 111 passes through the positioning groove 112 and extends into it, contacting the inner wall of the positioning groove 112. The cooperation between the positioning block 111 and the positioning groove 112 provides guidance for the up-and-down movement of the limiting baffle 110, preventing the baffle from shifting. The drive sliding assembly 1 is a conveying and limiting unit for the flange from the processing equipment to the inclined bucket, featuring electric drive, quick-release adaptation, and omnidirectional constraint design.

[0024] The feeding buffer assembly 2 includes an inclined bucket body 21, which is located on the right side of the slide body 11. The left side and bottom of the inclined bucket body 21 are open. The inclined bucket body 21 receives flanges sliding into the slide and guides the flanges downwards via an inclined channel. A stainless steel outer layer ensures load-bearing strength and prevents hard contact between the flanges. The inclined bucket body 21 is fixedly connected to the slide body 11 by bolts. The inclined bucket body 21 consists of a stainless steel outer layer and a high-density polyethylene inner layer. The high-density polyethylene inner layer is fixed to the inner wall of the stainless steel outer layer by bolts. The stainless steel outer layer is made of stainless steel plate, and the high-density polyethylene inner layer provides cushioning. Support blocks 22 are installed on both the front and back of the inclined bucket body 21. The support blocks 22 provide a rotation reference for the rubber buffer plate 23. The support blocks 22 are fixedly connected to the inclined bucket body 21 by welding. A rotating shaft is rotatably connected to the grooves on opposite sides of the two support blocks 22 via bearings. The surface of the rotating shaft is equipped with the rubber buffer plate 23. After the flange slides into the hopper, it contacts the rubber buffer plate 23. The plate absorbs the impact force through deformation and rotation, converting the hard impact between the flange and the metal into rolling friction, thus avoiding the flange edge from rubbing. It is made of nitrile rubber. Stabilizing blocks 24 are installed at the bottom of the front and back of the hopper body 21. The stabilizing blocks 24 provide a fixed reference for the buffer spring 25. The stabilizing blocks 24 are fixedly connected to the hopper body 21 by welding. The bottom of the stabilizing blocks 24 is connected to the top of the rubber buffer plate 23 through the buffer spring 25. One end of the buffer spring 25 is connected to the stabilizing block 24, and the other end is connected to the rubber buffer plate 23. When the flange impacts the buffer plate, the spring is compressed to further absorb the remaining impact force. After the flange slides past, the spring rebounds and drives the buffer plate to reset, waiting for the next flange. It is made of 60Si2Mn spring steel with an elastic coefficient of 5N / mm and a tensile strength ≥1800MPa. The feeding buffer assembly 2 is a buffer unit for the flange from the slide table to the material frame or the conveyor belt below. Through a double-layer structure and flexible buffer design, it absorbs the impact force of the flange sliding down and avoids hard contact damage.

[0025] In use, the processed flange is transferred to the placement frame 12 of the slide body 11. The front of the placement frame 12 is open, and the flange can be directly placed in. The controller starts the first electric push rod 15. The right end of the push rod pushes the mounting block 13, which drives the placement frame 12 and the flange to move along the slide body 11 towards the inclined bucket body 21. The slide body 11 is set with a 20° tilt angle. The gravity component of the flange is 15×sin20°×9.8≈50N for auxiliary conveying. The first electric push rod 15 only needs to output 80N of thrust to drive smoothly. When the first electric push rod 15 pushes to the end of the stroke, and the right side of the placement frame 12 is aligned with the left opening of the inclined bucket body 21, the controller receives the stroke sensor signal of the push rod, immediately stops the extension of the first electric push rod and starts self-locking. At this time, the flange is aligned with the inlet of the inclined bucket and is ready to slide in. Press the start button on the controller, and the second electric push rod 19 drives the limit baffle 110 to rise, releasing the constraint on the right side of the placement frame 12. Under the influence of the gravity component of the inclined slide, the flange slides out from the right side of the placement frame 12 and smoothly enters the inclined bucket body 21. It first contacts the high-density polyethylene inner layer of the inclined bucket, and absorbs the remaining impact force through the micro-deformation of the high-density polyethylene inner layer, avoiding the flange edge from hitting. Then it contacts the rubber buffer plate 23 outside the inclined bucket. The rubber buffer plate 23 absorbs the impact force through deformation, and at the same time rotates clockwise around the pivot of the support block 22, turning the hard impact into rolling friction. When the buffer plate rotates, it compresses the buffer spring 25 at the bottom of the stabilizing block 24, further absorbing the impact force. Then it falls directly into the conveyor belt or turnover frame below, completing the unloading.
