Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, and in particular to a feeding device for an ultrasonic valve bag packaging machine. Background Technology

[0002] Filling equipment is a type of machinery used to fill liquids, pastes, and powders into packaging containers according to certain metering standards. It plays a key role in many industries such as food, beverage, chemical, and pharmaceutical, and is an important piece of equipment for realizing the automation and standardization of product packaging. Ultrasonic valve bag packaging machines also belong to filling equipment. During operation, the material enters the cylinder from the hopper and is conveyed under the action of the screw. The metering device detects the material, and the screw stops when the set amount is reached, completing one feeding cycle. Then, it waits for the next packaging instruction.

[0003] A search revealed Chinese patent publication number CN111003223A, which discloses an inclined feeding device for a valve bag packaging machine. The device includes a conveying pipe and an inclined output component. The conveying pipe connects to the inclined output component, and the material enters the conveying pipe and is then output through the inclined output component. This invention, through the design of the inclined output component, can make the bag tilted during the filling process, thereby improving the filling rate and reducing the likelihood of powder spraying or overflow. However, in actual use, while the device reduces overflow by setting an inclined outlet, the seal between the outlet and the bag opening is insufficient during filling, affecting the filling effect and leading to dust or particulate matter leakage, thus polluting the working environment. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a feeding device for an ultrasonic valve bag packaging machine, which aims to improve the insufficient sealing between the discharge port and the bag opening in the prior art, thereby affecting the material filling effect and causing dust or particulate matter leakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for an ultrasonic valve bag packaging machine, comprising a fixed plate, a discharge pipe fixedly connected to the inner wall of the fixed plate, a transfer shell connected to the front end of the discharge pipe, a discharge port connected to the bottom of the transfer shell, a sealing sleeve fixedly connected to the middle of the outer wall of the discharge port, a variable frequency fan fixedly connected to the top rear side of the fixed plate, a negative pressure pipe connected to the bottom right side of the variable frequency fan, the bottom end of the negative pressure pipe connected to the right side of the sealing sleeve, an extraction pipe connected to the top right side of the variable frequency fan, a filter shell connected to the bottom end of the extraction pipe, a filter plate slidably connected to the inner wall of the filter shell, a one-way pipe connected to the front side of the filter shell, the bottom end of the one-way pipe connected to the front side of the transfer shell, and a fixing mechanism provided at the bottom rear side of the fixed plate.

[0006] The above technical solution achieves the following: with the bag opening and the discharge port inside the sealing sleeve initially wrapped and locked, the air inside the sealing sleeve is drawn out through the negative pressure pipe, thereby sealing the bag opening and the discharge port. At the same time, the dust generated by the material discharge inside the transfer shell is drawn out by the filter shell, and the dust particles are filtered through the filter plate, thereby reducing the leakage of dust or particulate matter.

[0007] As a further description of the above technical solution:

[0008] The fixing mechanism includes a positioning plate, the front side of which is fixedly connected to the rear side of the fixing plate. A limiting shell is fixedly connected to the bottom wall of the positioning plate. A threaded rod is rotatably connected to the inner bottom wall of the limiting shell. A knob is fixedly connected to the bottom end of the threaded rod. A clamp is threadedly connected to the outer wall of the threaded rod.

[0009] The above technical solution enables the clamp to be driven and have a tendency to rotate and displace under the rotation of the threaded rod. However, under the rotation restriction of the limiting shell, the clamp will not rotate, thus moving up and down along the direction of the threaded rod. With the cooperation of the positioning plate, the device is auxiliaryly fixed, which improves the stability during installation.

[0010] As a further description of the above technical solution:

[0011] The fixing mechanism also includes a rubber pad, the bottom wall of which is fixedly connected to the top wall of the clamp.

[0012] The above technical solution improves the fixation effect on the fixed position by connecting the rubber pad.

[0013] As a further description of the above technical solution:

[0014] A control switch is fixedly connected to the left side of the fixed plate, and the control switch is electrically connected to the variable frequency fan.

[0015] The above technical solution enables the variable frequency fan to be turned on and off when the control switch is connected.

[0016] As a further description of the above technical solution:

[0017] Multiple rubber strips are fixedly connected to the outer wall of the knob, and one side of each rubber strip is arranged in an equidistant ring.

[0018] The above technical solution improves the anti-slip effect of the knob by fixing it with multiple rubber strips.

[0019] As a further description of the above technical solution:

[0020] A rubber ring is fixedly installed at the top of the outer wall of the one-way tube, and the outer wall of the rubber ring is fixedly connected to the front side of the filter shell.

[0021] The above technical solution achieves protection of the connection point at the top of the one-way tube through the connection of the rubber ring.

[0022] As a further description of the above technical solution:

[0023] A stabilizing ring is fixedly connected to the rear end of the outer wall of the discharge pipe, and multiple support plates are fixedly connected to the front side of the stabilizing ring. The front side of the support plates is fixedly connected to the rear side of the fixed plate.

[0024] The above technical solution improves the stability of the discharge pipe by fixing the stabilizing ring and the support plate.

[0025] As a further description of the above technical solution:

[0026] A protective shell is fixedly connected to the top wall of the sealing sleeve, and a sealing ring is fixedly installed at the bottom of the outer wall of the negative pressure pipe.

[0027] The above technical solution enables the protection of the discharge port through the connection of the protective shell.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the bag opening and the discharge port inside the sealing sleeve are initially wrapped and locked together. Then, under the start of the variable frequency fan, the air inside the sealing sleeve is drawn out through the negative pressure pipe. Thus, the sealing sleeve wraps and seals the bag opening and the discharge port. Under the synchronous extraction of the one-way pipe, the dust generated by the material discharge inside the transfer shell is extracted. The dust is filtered through the filter shell, which ultimately avoids the pollution of the working environment and achieves the purpose of reducing dust or particulate matter leakage.

[0030] 2. In this utility model, by rotating the knob, the threaded rod rotates inside the limiting shell, thereby driving the clamp to rotate and displace. Under the rotation restriction of the limiting shell, the clamp moves along the direction of the threaded rod, thereby completing the auxiliary fixation of the device with the cooperation of the positioning plate, and improving the stability during installation.

[0038] 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.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an ultrasonic valve bag packaging machine feeding device, comprising a fixed plate 1, a discharge pipe 3 fixedly connected to the inner wall of the fixed plate 1, a transfer shell 4 connected to the front end of the discharge pipe 3, which transfers the material during conveying; a discharge port 5 connected to the bottom of the transfer shell 4; a sealing sleeve 8 fixedly connected to the middle of the outer wall of the discharge port 5, which seals the bag opening and the discharge port 5; a variable frequency fan 6 fixedly connected to the top rear side of the fixed plate 1; a negative pressure pipe 7 connected to the bottom right side of the variable frequency fan 6; and the bottom end of the negative pressure pipe 7 connected to the right side of the sealing sleeve 8, thereby controlling the flow of the variable frequency fan 6. When started, the negative pressure pipe 7 draws out the air inside the sealing sleeve 8, so that the bag opening and the discharge port 5 are sealed. The top right side of the variable frequency fan 6 is connected to the extraction pipe 9, and the bottom end of the extraction pipe 9 is connected to the filter shell 10. The inner wall of the filter shell 10 is slidably connected to the filter plate 11, and the dust and powder are filtered through the filter plate 11. The front side of the filter shell 10 is connected to the one-way pipe 12. At the same time, the dust and powder are extracted through the one-way pipe 12, and the material will not enter the interior of the filter shell 10 through the one-way pipe 12. The bottom end of the one-way pipe 12 is connected to the front side of the transfer shell 4. The bottom rear side of the fixing plate 1 is provided with a fixing mechanism 2.

[0040] Specifically, a preliminary connection is achieved by wrapping and locking the bag opening with the bottom of the inner discharge port 5 of the sealing sleeve 8. Under the starting action of the variable frequency fan 6, air is extracted through the negative pressure pipe 7, causing the air inside the sealing sleeve 8 to be extracted. As the air is continuously removed, the space inside the sealing sleeve 8 gradually shrinks, thereby achieving a tight wrapping and sealing of the bag opening and the discharge port 5. The one-way pipe 12 simultaneously performs extraction, ensuring that the dust and powder generated when the material is discharged from the inside of the transfer shell 4 are sucked in. The dust and powder are then uniformly filtered through the filter plate 11 inside the filter shell 10. The filtered airflow is finally discharged through the variable frequency fan 6, effectively avoiding pollution of the working environment and achieving the purpose of reducing dust or particulate matter leakage, thereby ensuring the cleanliness and safety of the working environment.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The fixing mechanism 2 includes a positioning plate 201, the front side of which is fixedly connected to the rear side of the fixing plate 1. The positioning plate 201 fixes the limiting shell 202. The bottom wall of the positioning plate 201 is fixedly connected to the limiting shell 202. The inner bottom wall of the limiting shell 202 is rotatably connected to a threaded rod 203. The bottom end of the threaded rod 203 is fixedly connected to a knob 204. By rotating the knob 204, the threaded rod 203 rotates synchronously. The outer wall of the threaded rod 203 is threadedly connected to a clamp 206, which then completes the lifting and lowering displacement. The fixing mechanism 2 also includes a rubber pad 207, the bottom wall of which is fixedly connected to the top wall of the clamp 206.

[0042] Specifically, during the device fixing process, by rotating the knob 204, the threaded rod 203 rotates inside the limiting shell 202. As the threaded rod 203 rotates, the clamp 206 is driven and tends to rotate and displace. Due to the presence of the limiting shell 202, the clamp 206 is restricted during rotation and therefore does not rotate. Instead, the clamp 206 will rise and fall along the direction of the threaded rod 203, allowing the clamp 206 to be adjusted in the vertical direction, thereby cooperating with the positioning plate 201. The clamp 206 can effectively assist the device installation process, ensuring that the stability of the device is improved during installation, enhancing the installation accuracy and reliability of the entire device. The rubber pad 207 further improves the fixing effect of the clamp 206.

[0043] Reference Figure 1 , Figure 4 and Figure 5 A control switch 16 is fixedly connected to the left side of the fixed plate 1, and the control switch 16 is electrically connected to the variable frequency fan 6; multiple rubber strips 205 are fixedly connected to the outer wall of the knob 204, and one side of the multiple rubber strips 205 are arranged in an equidistant ring; a rubber ring 13 is fixedly installed at the top of the outer wall of the one-way pipe 12, and the outer wall of the rubber ring 13 is fixedly connected to the front side of the filter shell 10.

[0044] Specifically, the control switch 16, which is electrically connected to the variable frequency fan 6, enables the variable frequency fan 6 to be turned on and off. Multiple rubber strips 205 improve the anti-slip effect of the knob 204, and the rubber ring 13 protects the connection point at the top of the one-way pipe 12.

[0045] Reference Figure 1 and Figure 2 A stabilizing ring 17 is fixedly connected to the rear end of the outer wall of the discharge pipe 3. Multiple support plates 18 are fixedly connected to the front side of the stabilizing ring 17. The front side of the support plates 18 is fixedly connected to the rear side of the fixed plate 1. A protective shell 15 is fixedly connected to the top wall of the sealing sleeve 8. A sealing ring 14 is fixedly installed at the bottom end of the outer wall of the negative pressure pipe 7.

[0046] Specifically, the stability of the discharge pipe 3 when conveying materials is improved by the stabilizing ring 17 and the support plate 18, and the outer wall of the discharge port 5 is protected by the protective shell 15.

[0047] Working principle: During use, the bag opening is wrapped and locked with the bottom end of the discharge port 5 inside the sealing sleeve 8 to complete the initial connection. Then, with the start of the variable frequency fan 6, air is drawn out through the negative pressure pipe 7, causing the air inside the sealing sleeve 8 to be extracted. At the same time, the internal space of the sealing sleeve 8 is reduced, and the sealing sleeve 8 achieves the purpose of wrapping and sealing the bag opening and the discharge port 5. Thus, under the synchronous extraction of the one-way pipe 12, the dust and powder generated inside the transfer shell 4 are extracted by the one-way pipe 12. The dust and powder are then filtered uniformly by the filter plate 11 inside the filter shell 10. The airflow is then discharged through the variable frequency fan 6, ultimately preventing the working environment from being polluted and reducing the leakage of dust or particulate matter. When fixing the device, the screw rod 203 rotates inside the limiting shell 202 by rotating the knob 204, thereby driving the clamp 206 to rotate and displace. Under the rotation restriction of the limiting shell 202, the clamp 206 will not rotate, thus achieving the lifting and lowering along the direction of the screw rod 203. This, together with the positioning plate 201, achieves the purpose of assisting in the installation of the device and improves the stability during installation.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
