A cylindrical ring feeder

Abstract

This application discloses a cylindrical annular feeder, including a feeder frame with a rotary feeding assembly mounted on the frame. The rotary feeding assembly includes a support column, a bracket mounting groove mounted on the upper end of the support column, an annular feeding unit disposed within the bracket mounting groove, and a feeding unit correspondingly disposed on one side of the annular feeding unit. This application achieves a "loading-transfer-feeding-resetting" cyclic operation of materials through an annularly arranged intermediate storage cylinder assembly, forming a continuous feeding flow and significantly improving the feeding efficiency per unit time. It is particularly suitable for multi-station or annular production lines. The pressure shaft breaks up the arch bridges formed by the material inside the cylinder, and the feeding guide shaft impacts and clears the discharge port. This dual action effectively solves the clogging problem that easily occurs with powdery and granular materials, ensuring that the material flows out stably and uniformly even under pure gravity.

Description

Technical Field

[0001] This application relates to the field of food processing technology, specifically to a cylindrical ring feeder. Background Technology

[0002] In automated production lines in the food industry, it is often necessary to continuously and quantitatively supply materials to multiple workstations or the same workstation. Traditional feeders mostly use linear or single-point feeding methods, which have problems such as low feeding efficiency, large footprint, and difficulty in perfectly matching with circular production lines. In addition, for materials that are prone to bridging or clogging, existing feeders often require manual intervention to clear the material, affecting the continuity of production and the degree of automation. Summary of the Invention

[0003] The technical problem to be solved by this application is to overcome the existing defects and provide a cylindrical annular feeder with a compact structure, high degree of automation, continuous annular feeding capability and built-in material-pumping function, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: a cylindrical annular feeder, comprising a feeder frame, wherein a rotary feeding assembly is disposed on the feeder frame. The rotary feeding assembly includes a support column, a bracket mounting groove mounted on the upper end of the support column, an annular feeding unit disposed within the bracket mounting groove, and a feeding chute unit correspondingly disposed on one side of the annular feeding unit.

[0005] The material feeding unit includes a material feeding bracket, a material feeding cylinder mounted on the material feeding bracket, a material feeding guide shaft connected to the output end of the material feeding cylinder 1, a side bracket set on one side of the material feeding bracket, an auxiliary pressing cylinder mounted on the side bracket, and a pressing shaft connected to the output end of the auxiliary pressing cylinder.

[0006] Furthermore, the annular feeding unit includes an intermediate pad and an intermediate storage cylinder. The intermediate pad is disposed within a bracket mounting groove, and a transmission assembly is located below the bracket mounting groove. The transmission assembly cooperates with a guide channel disposed on the intermediate pad, and the intermediate storage cylinder is disposed on the guide channel. The transmission assembly drives the entire annular feeding unit to rotate slowly within the bracket mounting groove.

[0007] Furthermore, a guide nozzle is provided on one side below the mounting groove of the bracket. The position of the guide nozzle corresponds to the material feeding unit, so that the material falling from the middle storage cylinder can be accurately guided into the downstream equipment through the guide nozzle.

[0008] Furthermore, one end of the bracket mounting slot is provided with a residual material discharge nozzle, which is used to discharge the remaining material in the annular feeding unit when the machine is stopped for maintenance or the equipment is emptied.

[0009] Furthermore, the feeder frame is equipped with a storage rack, and the outlet of the storage rack is correspondingly set with the inlet of the intermediate storage cylinder in the annular feeding unit to realize automatic feeding of the annular feeding unit.

[0010] Furthermore, a maintenance frame is provided on one side of the feeder frame. The maintenance frame includes a single-layer support and a double-layer support arranged vertically, which facilitates the operator to maintain and repair the upper part of the equipment, especially the feeding unit and the annular feeding unit.

[0011] Compared with the prior art, the beneficial effects of this application are: this application realizes the "loading-transfer-feeding-resetting" cycle operation of materials through the ring-shaped intermediate storage cylinder group, forming a continuous feeding flow, which significantly improves the feeding efficiency per unit time, and is especially suitable for multi-station or ring production lines.

[0012] The material is pressed down by the pressure shaft to break the arch bridge formed by the material inside the cylinder, and then the material guide shaft is used to impact and clear the discharge port. This dual action effectively solves the problem of blockage that easily occurs in powdery and granular materials, ensuring that the material can flow out stably and evenly under the action of pure gravity.

[0013] The material rack outlet is precisely aligned with the intermediate storage cylinder that rotates below it, enabling directional and quantitative feeding, reducing material spillage and dust escape. The combined design of the edge groove and the residual material outlet can effectively collect and guide the spilled or residual material during cleaning, reducing material loss.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. For the convenience of description and understanding, the embodiments in this application are referred to below as... Figure 2 The description above is for illustrative purposes only. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0020] Please see Figure 1-4 A cylindrical annular feeder is mounted on a feeder frame 10 made of profiles. The frame 10 typically has anchor bolt holes at its bottom, which, along with adjustable feet, ensure the frame's stability. A maintenance rack is fixedly mounted on the front side of the frame 10, the side facing the operator. This maintenance rack has two layers: the lower second-layer support 4 is at a moderate height, allowing the operator to stand and perform preliminary inspections and maintenance on the feeder's central components; the upper first-layer support 15 has a platform height approximately level with the operating plane of the annular feeding unit 12, facilitating close observation of the material feeding unit, storage rack 8, and the annular feeding unit 12's operating status.

[0021] The support column 11 is a square tube profile, and its lower end is firmly and vertically fixed to the frame position of the feeder frame 10.

[0022] The main body of the bracket mounting groove 7 is a hollow, annular, open structure. It is fixed to the support column 11 at its bottom, and the interior of the bracket mounting groove 7 forms the installation and operating space for the annular feeding unit 12.

[0023] The annular feeding unit 12 is located within the support mounting groove 7. Its foundation is an intermediate pad 5, the shape of which matches the inner cavity of the support mounting groove 7. Circular holes are evenly distributed along the circumference of the upper surface of the intermediate pad 5, and cylindrical intermediate storage cylinders 13 are installed in these holes. These intermediate storage cylinders 13 have openings at their bottoms to facilitate material flow out under gravity.

[0024] The material feeding unit is mounted on the top beam of the feeder frame 10 via its material feeding bracket, ensuring that it is directly above the guide nozzle located on the side below the bracket mounting slot 7.

[0025] Specifically, the mounting position of the material-push cylinder 1 on the material-push bracket ensures that its front-end material-push guide shaft 3 can be precisely aligned with the discharge port at the bottom of the intermediate material storage cylinder 13, which has rotated to this position. Simultaneously, the auxiliary pressing cylinder 2 mounted on the side bracket has its end-end pressing shaft 14 precisely aligned with the top opening of the intermediate material storage cylinder 13. The linkage between the material-push unit and the annular feeding unit 12 is typically controlled by a PLC program to achieve an automated cycle of "rotation-positioning-pressing-push-re-rotation".

[0026] The storage rack 8 is fixedly installed on the top of the feeder frame 10 by support legs and spans across the top of the annular feeding unit 12. Its discharge port faces downward, ensuring that when the intermediate storage cylinder 13 rotates to its direct position, it can smoothly receive the material from the storage rack 8 and complete the automatic feeding.

[0027] If the contents are not filled into the intermediate storage cylinder 13, they will leak into the edge groove formed by the bracket mounting groove 7 and the intermediate pad 5.

[0028] The residual material outlet 6 is installed on the annular outer wall of the bracket mounting groove 7, and its inlet is located in the edge groove formed by the bracket mounting groove 7 and the intermediate pad 5. When it is necessary to empty the equipment, the material can be guided to the external collection container.

[0029] The drive unit is located below the bracket mounting slot 7. When the drive mechanism is activated, it drives the gears mounted on the bracket mounting slot 7 to rotate. As the gears rotate, the intermediate storage cylinders 13 located between the gears rotate, enabling each intermediate storage cylinder 13 to rotate around the annular channel in the intermediate pad 5, thus transferring the intermediate storage cylinders 13.

[0030] In operation: The drive unit rotates intermittently according to a set program, driving the annular feeding unit 12 in steps. When a fully loaded intermediate storage cylinder 13 rotates to the feeding station and stops, the auxiliary pressing cylinder 2 acts first, and the pressing shaft 14 presses down to break the material arch; then the feeding cylinder 1 acts quickly, and the feeding guide shaft 3 impacts and clears the discharge port; the material falls into the downstream equipment through the guide nozzle under the action of gravity. After completion, the equipment rotates, the empty cylinder moves away, and the full cylinder enters, while a new empty cylinder moves to the storage rack 8 to receive replenishment. This cycle is repeated to achieve uninterrupted annular automated feeding.

[0031] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
