Description

Technical Field

[0001] This utility model relates to a material feeding and dust removal mechanism, and more particularly to a material feeding and dust removal mechanism for a servo bag feeding packaging machine, belonging to the technical field of servo bag feeding packaging machines. Background Technology

[0002] Currently, servo bag-feeding packaging machines are highly efficient automated packaging equipment widely used in the food, pharmaceutical, chemical, and daily chemical industries. They can package products including, but not limited to, solids, liquids, sauces, granules, and powders. Driven by a servo motor, it can precisely control each stage of the packaging process, such as bag picking, opening, material feeding, and sealing. The specific packaging process is as follows: First, the operator places the packaging bag in the bag picking section of the machine; second, the machine's mechanical gripper picks up and opens the bag, and the feeding device feeds material into the packaging bag; finally, the bag is sealed and output after feeding. The entire process requires no manual operation.

[0003] like Figure 1 As shown, the feeding device of the existing servo bag packaging machine includes a screw (1) and a conical hopper (2). Powdered material is fed into the conical hopper (2) through the screw (1) and then falls into the packaging bag (5) below from the feeding port (21) of the conical hopper (2). However, if the flowability of the powdered material is poor, the feeding port (21) is easily blocked. At this time, not only is it necessary to manually unclog the feeding port (21) in real time, but it may also cause inaccurate measurement of the material in the packaging bag (5) and even cause the equipment to stop operating, affecting the packaging efficiency. In addition, when the powdered material falls into the packaging bag (5) from the feeding port (21), a small amount of powdered material often falls around the opening of the packaging bag (5). When the packaging bag (5) is sealed after the material is fed, the sealing effect is affected by a small amount of powdered material sticking to the opening of the bag, and it also causes environmental pollution to the production workshop.

[0004] Therefore, there is an urgent need to develop and design a feeding and dust removal mechanism suitable for servo bag packaging machines. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides a material feeding and dust removal mechanism for a servo bag feeding packaging machine, thereby achieving the technical objective of smooth material discharge from the conical hopper and dust-free bag openings.

[0006] To achieve the above technical objectives, this utility model provides a feeding and dust removal mechanism for a servo bag feeding packaging machine. The servo bag feeding packaging machine includes a conical hopper with a feeding port at the bottom, a screw inserted inside the conical hopper, and a rotating disk equipped with several pairs of mechanical claws.

[0007] The material feeding and dust removal mechanism includes a vibrator installed on the outer wall of the feeding port, and dust suction ports symmetrically opened on both sides of the outer wall of the feeding port, and the dust suction ports are connected to a vacuum cleaner through a hose.

[0008] Furthermore, this utility model also includes a bag mouth dust removal assembly placed in front of the conical hopper above the conveying trajectory of the mechanical claw; the bag mouth dust removal assembly includes a speed regulating motor, a dust removal hood mounted on a bracket, and a rotating shaft, bushing, and roller brush placed inside the dust removal hood;

[0009] The dust removal hood has a suction port on its top surface, which is connected to a vacuum cleaner via a flexible hose. The two ends of the rotating shaft are respectively inserted into the two side walls of the dust removal hood, with one end extending out of the dust removal hood and connected to the output shaft of the speed-regulating motor. A bushing is fitted on the rotating shaft, and several roller brushes are fitted on the bushing, with the roller brushes able to contact the opening of the packaging bag held by the mechanical claw.

[0010] Furthermore, in this invention, when the rear pair of mechanical claws rests below the discharge port of the conical hopper, the position where the front pair of mechanical claws rests is below the bag mouth dust removal component, and the roller brush can contact the bag mouth of the packaging bag held by the front pair of mechanical claws.

[0011] Specifically, the vibrator of this invention is a starting turbine type vibrator.

[0012] Specifically, in this invention, the bushing and the roller brush are made of silicone material.

[0013] Specifically, the dust cover of this utility model is made of stainless steel.

[0014] In summary, this utility model has the functions of material feeding and dust removal, achieving the technical effects of smooth material discharge from the conical hopper and dust-free packaging bag openings, and has the following technical advantages:

[0015] Firstly, during the material feeding operation, the packaging bag moves below the conical hopper's discharge port. A vibrator vibrates the discharge port, causing the powdery material to be fed while vibrating. This prevents clogging at the discharge port, ensuring smooth material flow and maintaining production efficiency. Simultaneously, dust suction ports on both sides of the discharge port remove any small amounts of powdery material that rises from the port, ensuring a clean production environment.

[0016] Secondly, after the material unloading operation is completed, the packaging bag moves forward to the bottom of the bag opening dust removal component. The powdery material at the bag opening is then sucked away through the suction port on the top surface of the dust removal hood. At the same time, several roller brushes inside the dust removal hood clean the powdery material at the bag opening, ensuring the sealing effect of the sealing operation. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] In the description of this application, terms such as "connection" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Those skilled in the art will understand the specific meaning of these terms in this application according to the specific circumstances.

[0023] In the description of this application, terms such as "up", "down", "left", "right", "front", and "back" are used only to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] like Figure 1 As shown, the existing servo bag packaging machine includes a conical hopper 2 with a feeding port 21 at the bottom, a screw 1 inserted inside the conical hopper 2, and a rotating disk 3 equipped with several pairs of mechanical claws 4.

[0025] In practice, each pair of robotic claws 4 grasps an open packaging bag 5 and transports it to the bottom of the discharge port 21 of the conical hopper 2 via the rotary table 3. The powdery material is fed into the conical hopper 2 via the screw 1 and then falls into the packaging bag 5 from the discharge port 21. After the material is discharged, the first pair of robotic claws 4 transports the packaging bag 5 forward via the rotary table 3, while the second pair of robotic claws 4 transports the next packaging bag 5 to the bottom of the discharge port 21 and repeats the material discharge operation.

[0026] like Figure 2As shown, this utility model provides a feeding and dust removal mechanism for a servo bag packaging machine, including a vibrator 6 installed on the outer wall of the feeding port 21 of the conical hopper 2, and dust suction ports 7 symmetrically opened on both sides of the outer wall of the feeding port 21, and the dust suction ports 7 are connected to a vacuum cleaner 10 through a hose.

[0027] In other embodiments, the vibrator 6 is a start-up turbine type vibrator.

[0028] In practice, during the material feeding operation, the packaging bag 5 is transported to the bottom of the discharge port 21 of the conical hopper 2. The vibrator 6 is then turned on to vibrate the discharge port 21 of the conical hopper 2, thus enabling the powdery material to be fed while vibrating, preventing the powdery material from clogging at the discharge port 21 and ensuring smooth material feeding. At the same time, the vacuum cleaner 10 is turned on, and the small amount of powdery material raised at the discharge port 21 is sucked away through the suction ports 7 on both sides of the outer wall of the discharge port 21, while the vast majority of the powdery material still flows downward into the packaging bag 5.

[0029] like Figure 2 , Figure 3 As shown, this utility model also includes a bag mouth dust removal assembly placed in front of the conical bucket 2 above the conveying trajectory of the mechanical claw 4; the bag mouth dust removal assembly includes a speed regulating motor 8, a dust removal hood 9 mounted on the bracket 11, and a rotating shaft 91, a bushing 92 and a roller brush 93 placed inside the dust removal hood 9, which are described in detail below.

[0030] The dust cover 9 has a suction port 7 on its top surface, and the suction port 7 is connected to the vacuum cleaner 10 through a hose. In specific implementation, the hoses connected to the suction ports 7 on both sides of the discharge port 21 can be interconnected with the hoses connected to the suction ports 7 on the top surface of the dust cover 9, and then connected to the vacuum cleaner 10 through the hoses connected to the suction ports 7 on the top surface of the dust cover 9.

[0031] The two ends of the rotating shaft 91 are respectively inserted into the two side walls of the dust collector 9, with one end extending out of the dust collector 9 and connected to the output shaft of the speed-regulating motor 8. A bushing 92 is fitted on the part of the rotating shaft 91 inside the dust collector 9. Several roller brushes 93 are fitted on the bushing 92, and the roller brushes 93 can contact the opening of the packaging bag 5.

[0032] Furthermore, when the rear pair of mechanical claws 4 stops below the feed inlet 21, the position where the front pair of mechanical claws 4 stops is below the bag mouth dust removal component, and the roller brush 93 inside the bag mouth dust removal component can contact the bag mouth of the packaging bag 5 on the front pair of mechanical claws 4.

[0033] In other embodiments, the bushing 92 and the roller brush 93 are made of silicone. Because both the bushing 92 and the roller brush 93 have a soft touch, they provide protection for the packaging bag.

[0034] In other embodiments, the dust cover 9 is made of stainless steel.

[0035] In practice, when a large amount of powdery material enters the packaging bag 5, a small amount of powdery material will fall near the opening of the packaging bag 5. After the material feeding operation is completed, the packaging bag 5 continues to move forward along the conveying direction, that is, the running direction of the rotary disc 3. Then, the next packaging bag 5 stops below the feeding port 21 and the feeding operation is repeated. The position where the previous packaging bag 5 stops is below the location of the bag opening dust removal component. At this time, the vacuum cleaner 10 is turned on. On the one hand, it removes the small amount of powdery material raised at the feeding port 21 through the suction ports 7 on both sides of the outer wall of the feeding port 21; on the other hand, it removes the powdery material at the opening of the packaging bag 5 through the suction ports 7 on the top surface of the dust removal hood 9. At the same time, the speed-regulating motor 8 is turned on, and several roller brushes 93 inside the dust removal hood 9 rotate accordingly to clean the powdery material at the opening of the packaging bag 5, ensuring the cleanliness of the bag opening and thus ensuring the sealing effect of the subsequent sealing operation.

Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, based on the ideas of this utility model, modifications can be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the ideas and scope of the technical solutions of the embodiments of this utility model.
