Description

Technical Field

[0001] This utility model relates to the field of material packaging, specifically a material loading device. Background Technology

[0002] Packaging machines are an important category of packaging machinery and equipment. Based on the different forms of materials they process, they can be mainly divided into liquid packaging machines, paste packaging machines, powder packaging machines, and granule packaging machines. If classified according to the degree of automation, they can be divided into semi-automatic packaging machines and fully automatic packaging production lines.

[0003] When loading granular or powdered materials, a common structure involves installing a movable baffle at the discharge port below the hopper. This baffle is typically driven by a pneumatic device to rotate or translate, enabling intermittent discharge and quantitative packaging of the material. However, this method has significant shortcomings in long-term operation: due to the frequent opening and closing and repeated movement of the baffle, the gap between it and the hopper discharge port increases. As the equipment is used over time, this gap gradually widens, leading to continuous leakage of material during non-loading periods, affecting loading accuracy and production stability. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a feeding device for packaging powder / small granular materials. The feeding device drives the feeding rod with a cylinder to move the material, which can avoid the gap caused by repeated movement of the baffle and leakage of material, and also facilitates quantitative packaging of powder / small granular materials.

[0005] Specifically, a feeding device includes a frame, a support block, a hopper, a rotary drum, a telescopic device, and a discharge pipe;

[0006] The hopper is mounted on the frame via the support block;

[0007] The rotating drum is rotatably mounted inside the support block. A rotating drum cylinder is mounted on the frame. The telescopic rod of the rotating drum cylinder is connected to the rotating drum and controls the rotation direction of the rotating drum. The telescopic device is mounted on the frame and has a telescopic part that extends through the rotating drum.

[0008] The discharge pipe is located at the end of the support block away from the telescopic device, and is used to guide the powder / small granular material to be conveyed out of the support block;

[0009] The hopper and the discharge pipe are kept connected and disconnected by the rotation of the rotating drum.

[0010] Furthermore, the two ends of the rotating drum are closed and connected to the support block by a bearing connection through the rod body. Three through holes communicating with the interior are evenly distributed at 90° on the outer end face of the rotating drum. One end of the rod body extends to the outer end of the support block and is rotatably connected to the telescopic rod of the rotating drum cylinder. The other end of the rotating drum cylinder is rotatably mounted on the frame.

[0011] Furthermore, the telescopic device includes a pushing cylinder and a mounting cylinder, the pushing cylinder is fixedly mounted on the frame, and the telescopic rod of the pushing cylinder is the telescopic part;

[0012] The mounting cylinder is positioned between the pusher cylinder and the support block to mount the feeding rod at the outer end of the pusher cylinder's telescopic section.

[0013] Furthermore, the outer diameter of the end of the feeding rod, the inner diameter of the discharge pipe, and the discharge hole diameter of the hopper are all adapted to the through hole diameter at the outer end of the rotating drum.

[0014] Furthermore, the discharge pipe is an inclined pipe, with one end pointing downwards toward the placement plate located on the side of the frame.

[0015] Furthermore, the discharge port of the hopper is movably connected to the support block by a pipe clamp, and a cover plate is movably installed on the top of the hopper.

[0016] This utility model has the following beneficial effects:

[0017] This utility model is reasonably designed and easy to use. During filling, the rotating drum is rotated to keep the through holes of the drum aligned with the hopper, the telescopic device, and the discharge pipe. The telescopic device is activated at regular intervals to achieve quantitative packaging of powder / small granular materials. This not only makes filling convenient but also prevents leakage.

[0018] In this invention, the shape of the rotating drum is designed to facilitate filling and prevent leakage. Furthermore, rotating the drum during idle periods will not cause leakage.

[0019] By setting a cover plate on top of the hopper and adjusting the hopper's installation method, debris can be prevented from falling into the hopper, and the interior can be easily cleaned. Attached Figure Description

[0030] The following will be combined with the appendix Figures 1-9 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] This utility model provides a feeding device through improvements, which can be implemented as follows: A feeding device includes a frame 1, a support block 8, a hopper 5, a rotating drum 13, a telescopic device, and a discharge pipe 9;

[0032] The hopper 5 is mounted on the frame 1 via the support block 8.

[0033] The rotating drum 13 is rotatably disposed inside the support block 8. A rotating drum cylinder 4 is installed on the frame. The telescopic rod of the rotating drum cylinder is connected to the rotating drum and controls the rotation direction of the rotating drum. The telescopic device is disposed on the frame 1. The telescopic device has a telescopic part, and the extended telescopic part passes through the rotating drum 13.

[0034] The discharge pipe 9 is located at the end of the support block 8 away from the telescopic device, and is used to guide the powder / small granular material to be conveyed out of the support block;

[0035] The hopper 5 and the discharge pipe 9 are kept connected and disconnected by the rotation of the rotating drum 13.

[0036] In this embodiment, the two ends of the rotating drum 13 are closed and connected to the support block 8 by a bearing connection through the rod body 11. Three through holes 131 that communicate with the interior are evenly distributed at 90° on the outer end face of the rotating drum 13. One end of the rod body 11 extends to the outer end of the support block 8 and is rotatably connected to the telescopic rod of the rotating drum cylinder 4. The other end of the rotating drum cylinder 4 is rotatably mounted on the frame 1.

[0037] For example, such as Figure 9 As shown, the telescopic rod of the rotary cylinder 4 is connected to the rod body 11 via a connecting rod. The telescopic movement of the rotary cylinder 4 drives the rotary cylinder 13 to rotate.

[0038] In this embodiment, the telescopic device includes a pusher cylinder 2 and a mounting cylinder 3. The pusher cylinder 2 is fixedly mounted on the frame 1, and the telescopic rod of the pusher cylinder is the telescopic part.

[0039] The mounting cylinder 3 is positioned between the pusher cylinder 2 and the support block 8 to mount the feeding rod 12 at the outer end of the telescopic part of the pusher cylinder 2.

[0040] In this embodiment, the outer diameter of the end of the feeding rod 12, the inner diameter of the discharge pipe 9, and the discharge hole diameter of the hopper 5 are all adapted to the through hole diameter at the outer end of the rotating drum 13.

[0041] In this embodiment, the discharge pipe 9 is an inclined pipe, with one end pointing vertically downward toward the placement plate 10 disposed on the side of the frame 1.

[0042] In this embodiment, the discharge hole of the hopper 5 is movably connected to the support block 8 by a pipe clamp 7, and a cover plate 6 is movably installed on the top of the hopper 5.

[0043] When filling materials, the filling device first starts the rotary cylinder 4 to drive the rotary cylinder 13 to rotate, keeping the three through holes at the outer end of the rotary cylinder 13 corresponding to the hopper 5, the discharge pipe 9, and the feeding rod 12 respectively. Then, the material to be filled is poured into the hopper 5 and the cover plate 6 is closed. Finally, the packaging bag is put on the outer end of the discharge pipe 9 and the pushing cylinder 2 is activated to extend, driving the feeding rod 12 to move and push the material that has fallen from the hopper 5 into the rotary cylinder 13 due to gravity into the discharge pipe 9 (the discharge pipe 9, the through holes of the rotary cylinder 13, and the pushing cylinder 2 are in a straight line). Finally, under the action of gravity, it falls into the container 15. The container can be a bag or box for turnover, thus completing the bagging. The material is put into the container so that the workers can move to the next process (such as the next mixing process or sealing process). In the layout of the production line, this device can realize the auxiliary material addition process of meat product processing.

[0044] To facilitate container placement, multiple containers 15 can be placed on the placement plate or multiple containers 15 can be placed on an external conveying device 14. The external conveying device can be installed on the placement plate or located at the position of the placement plate and move synchronously with the pushing cylinder so that a container can receive the material each time it is dropped.

[0045] When the feeding device is not loading material, simply reverse the rotary cylinder 4 to rotate the rotary cylinder 13 and keep the hopper 5 from contacting the through hole of the rotary cylinder 13 to prevent material leakage.

[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
