Description

Technical Field

[0001] This application belongs to the field of powder feeding technology, specifically a powder feeding machine. Background Technology

[0002] With the comprehensive advancement of industrialization and the rapid development of industrial production, many industrial processes require the input of bagged dry powder. Traditionally, many factories still rely on manual input of this powder, which is labor-intensive and generates significant dust pollution, seriously impacting worker health. Therefore, automated bagged dry powder feeding devices are widely used. Currently, dry powder feeding typically employs a combination of screw conveyors, bag-breaking hoppers, and elevators.

[0003] CN214493637U discloses a gravity-type bag-breaking machine for unpacking granular or powder packaging, relating to the field of granular or powder packaging technology. It includes a support frame and a bag-breaking device, as well as a hopper, a screen, and a discharge valve. The hopper is entirely mounted on the support frame, and the bag-breaking device is located inside the hopper. The bag-breaking device has sharpened blades. The screen is located below the bag-breaking device, and the discharge valve is located at the outlet of the hopper. Utilizing the weight of the packaging bag itself, as the bag descends, it comes into contact with the stationary bag-breaking blade assembly. The sharpened blades puncture the lower part of the packaging bag, allowing the granular or powdery material to fall into the hopper.

[0004] However, in a closed space, powder may accumulate at the puncture site due to gravity or friction between particles, resulting in very little powder flowing out. In existing technology, it is usually necessary to manually tap the packaging bag to improve the flowability of the powder inside the bag, so that the powder can be loosened from the concave part or the powder adhering to the inner wall, making it easier to flow out through the puncture hole. Utility Model Content

[0005] The purpose of this application is to solve the above-mentioned problems and provide a powder feeding machine. This powder feeding machine can drive the plate to move in a way that maintains the gap size through a horizontal drive structure, shake the powder packaging bag, or move in an alternating manner to impact the powder packaging bag, thereby improving the flowability of the powder inside the bag and making it easier for the powder to flow out through the punctured hole.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] refer to Figures 1-5 A powder feeding machine includes a frame 1, a receiving unit 2 connected to the frame 1, and a feeding unit 3 communicating with the receiving unit 2. The receiving unit 2 is provided with a spike mechanism 21, which is used to puncture the powder packaging bag conveyed from the external overhead crane 4. The frame 1 is also provided with a symmetrically arranged horizontal drive mechanism 11 and a plate 12 connected to the output end of the horizontal drive mechanism 11. The symmetrically arranged plates 12 have a gap 13 for accommodating the powder packaging bag. The horizontal drive mechanism 11 is used to drive the plates 12 to move in a manner that maintains the size of the gap 13.

[0027] In this design, the operator hangs the powder packaging bag on the overhead crane 4 and operates the overhead crane 4 to drive the powder packaging bag to the gap 13. Then, the operator drives the powder packaging bag to move downward and contact the spike mechanism 21, so that the spike mechanism 21 punctures the powder packaging bag. The horizontal drive mechanism 11 drives the plate 12 to move in a way that maintains the size of the gap 13. In other words, the operator pre-sets the size of the gap 13 to match the powder packaging bag. By moving in a way that maintains the size of the gap 13, the operator shakes the powder packaging bag to improve the flowability of the powder inside the bag, making it easier for the powder to flow out through the punctured hole.

[0028] In this embodiment, the horizontal drive mechanism 11 includes a drive motor 111, a transmission mechanism 112, and a push rod 113. The drive motor 111 is connected to one side of the frame 1. One end of the transmission mechanism 112 is connected to the power output end of the drive motor 111. The push rod 113 is slidably connected to the frame 1. The other end of the transmission mechanism 112 is connected to one end of the push rod 113. The other end of the push rod 113 is connected to the plate 12. The drive motor 111 drives the push rod 113 to move horizontally through the transmission mechanism 112.

[0029] Specifically, the rotational output of the drive motor 111 is changed to the horizontal output of the push rod 113 through the transmission mechanism 112. The drive motor 111 is distinguished by the left and right sides of the frame 1. The drive motor 111 on the left side of the frame 1 and the drive motor 111 on the right side of the frame 1 move synchronously. That is, when the drive motor 111 on the left side of the frame 1 drives the push rod 113 to push out, the drive motor 111 on the right side of the frame 1 drives the push rod 113 to retract, so as to move in a way that ensures the size of the gap 13 and shakes the powder packaging bag.

[0030] Preferably, the vertical cross-section of the push rod 113 is square. In actual use, although the transmission mechanism 112 is connected, it is still necessary to avoid relative rotation between the push rod 113 and the frame 1. Therefore, the push rod 113 is designed with a square vertical cross-section. Of course, any shape other than a cylinder can achieve this function. The operator can choose to use other non-cylindrical shapes according to the actual situation.

[0031] Furthermore, the transmission mechanism 112 includes a guide rail 1121 connected to one end of the push rod 113, a slider 1122 slidably connected to the guide rail 1121, and a connecting rod 1123 rotatably connected to the slider 1122. The guide rail 1121 is arranged vertically, and the connecting rod 1123 is connected to the power output end of the drive motor 111.

[0032] In practical applications, the rotation of the drive motor 111 will cause the connecting rod 1123 to swing. When the connecting rod 1123 swings, it cooperates with the slider 1122. When the push rod 113 is slidably connected to the frame 1, the push rod 113 is driven to move horizontally, thereby driving the plate 12 to move.

[0033] In this embodiment, a horizontally arranged guide rod 114 is also provided on one side of the guide rail 1121, and the guide rod 114 is slidably connected to the frame 1. The guide rod 114 can provide stability for the movement of the push rod 113 and can also provide auxiliary support for the push rod 113.

[0034] Preferably, one end of the plate 12 is bent away from the gap 13, forming the entrance end of the gap 13. With this design, the entrance end of the gap 13 is larger, making it easier for the powder packaging bag to enter the gap 13.

[0035] In this embodiment, the receiving unit 2 is a receiving funnel, and the spike mechanism 21 includes a support frame 211 connected inside the receiving funnel and spikes 212 connected to the support frame 211. For details regarding the receiving funnel, support frame 211, and spikes 212, please refer to the receiving funnel and bag-breaking knife disclosed in Chinese Patent CN119043818A. Therefore, the specific structure and working principle of the receiving funnel, support frame 211, and spikes 212 will not be described in detail in this embodiment.

[0036] Furthermore, the feeding unit 3 is a screw conveyor mechanism, and the inlet end of the screw conveyor mechanism is connected to the output end of the receiving unit 2. Rotary conveyor mechanisms are a conventional design in this field, so they will not be described in detail here.

[0037] Example 2

[0038] refer to Figures 1-5 The powder feeding machine in this embodiment 2 has the same structure as that in embodiment 1. The difference is that the plate 12 in this embodiment 2 moves in an alternating manner.

[0039] Specifically, the drive motors 111 are distinguished by the left and right sides of the frame 1. The drive motor 111 on the left side of the frame 1 and the drive motor 111 on the right side of the frame 1 move alternately. That is, after the drive motor 111 on the left side of the frame 1 drives the push rod 113 to extend and retract, the drive motor 111 on the right side of the frame 1 drives the push rod 113 to extend and retract, impacting the powder packaging bag, improving the flowability of the powder inside the bag, and making it easier for the powder to flow out through the punctured hole.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
