Description

Technical Field

[0001] This utility model belongs to the field of material filling technology and relates to a material filling device. Background Technology

[0002] Filling is an industrial process that uses mechanical devices to inject fluid, semi-fluid, or granular materials into packaging containers in a set amount. It is widely used in the food, pharmaceutical, and chemical industries, and the performance of the equipment directly determines production efficiency and product quality.

[0003] In general, small and medium-sized enterprises typically involve workers placing material buckets under the pipes connected to the filling machine, opening a manual valve, and allowing material to flow from the pipes into the buckets. When the buckets are nearly full, the workers close the manual valves and replace the buckets, repeating this cycle. This manual operation is labor-intensive, cannot be carried out continuously, and has low efficiency.

[0004] To address the limitations of manual operation, limited non-stop barrel changing can be achieved through the design of robotic arms or buffer roller conveyors. This involves using robotic arms to replace manual labor and shorten barrel changing time. Alternatively, roller conveyor structures can transport empty barrels downstream to the material conveying pipeline, resulting in minimal downtime, covering only the barrel changing period. While these methods reduce manpower, the procurement and maintenance costs are relatively high, and true non-stop operation is not possible. The constant cycle of stopping and starting leads to significant wear and tear on the filling equipment, reducing its lifespan. Utility Model Content

[0005] The purpose of this utility model is to provide a material filling device that aims to solve the problems of material filling in the prior art being unable to achieve non-stop operation and having low work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a material filling device, comprising a conveying pipe, a three-way reversing valve, a material hopper, a weight sensor, and a controller; the conveying pipe includes an inlet pipe and two outlet pipes; the three-way reversing valve has one inlet and two outlets, the inlet being connected to the inlet pipe, and the two outlets being detachably connected to their respective outlet pipes; the material hopper comprises two hoppers, each located on one side of its corresponding outlet pipe and used to hold the material flowing out of the outlet pipe; the weight sensor is located below the material hopper and is used to detect the mass of the material hopper in real time; the three-way reversing valve is a solenoid valve; the weight sensor is electrically connected to the controller, and the controller is electrically connected to the solenoid valve; in the working state, the inlet and the inlet pipe are kept connected, one outlet is connected to its corresponding outlet pipe, and the other outlet pipe and its corresponding outlet are closed.

[0007] Optionally, the material filling equipment further includes a lifting platform, on which the material hopper and the weight sensor are placed.

[0008] Optionally, the lifting platform includes a motor, a horizontal carrier plate, and a lifting mechanism. The material bucket and the weight sensor are placed on the horizontal carrier plate, the horizontal carrier plate is mounted on the lifting mechanism, and the motor drives the lifting mechanism to move up and down.

[0009] Optionally, the lifting mechanism includes a base, a lead screw, a nut, a guide rod, a first connecting rod, and a second connecting rod; the lead screw is mounted on the base and connected to the output end of the motor; the nut is sleeved on the outer periphery of the lead screw; the guide rod and the nut are fixedly connected; one end of the first connecting rod is rotatably connected to the guide rod; the other end of the first connecting rod is rotatably connected to one side of the horizontal carrier plate; the other side of the horizontal carrier plate is provided with a sliding groove; one end of the second connecting rod is rotatably mounted on the base; the other end of the second connecting rod is rotatably mounted in the sliding groove, so that the end of the second connecting rod slides along the sliding groove.

[0010] Optionally, there are two first connecting rods and two second connecting rods. One end of each of the two first connecting rods is rotatably connected to both ends of the guide rod, and the other end of each of the two first connecting rods is rotatably connected to two positions on the same side of the horizontal carrier plate. The other side of the horizontal carrier plate is provided with two spaced-apart sliding grooves. One end of each of the two second connecting rods is rotatably mounted on two positions on the base, and the other end of each of the two second connecting rods is correspondingly mounted in the two sliding grooves. Each first connecting rod and its corresponding second connecting rod intersect and are rotatably connected at the intersection position by a pin.

[0011] Optionally, the ends of the material bucket and the discharge pipe are detachably connected; or, the end of the discharge pipe is placed inside the material bucket; or, the discharge pipe is a rigid pipe and the end of the discharge pipe is located above the inlet of the material bucket.

[0012] Optionally, the weight sensor is equipped with a display screen for displaying real-time data.

[0013] This utility model has at least one of the following beneficial effects:

[0014] 1. By setting up a three-way reversing valve and two material hoppers, the two outlets of the three-way reversing valve correspond to different material hoppers. When one material hopper is full, the operator can change the direction of the three-way reversing valve so that the material flows to the other empty material hopper. This enables the filling machine to operate continuously without stopping, reduces wear and tear on the filling equipment, and extends its service life.

[0015] 2. The three-way reversing valve is set as a solenoid valve and is electrically connected to the controller. A weight sensor is placed under the material bucket, which is also electrically connected to the controller. When the weight of a material bucket and the material in the bucket reaches the preset value, the controller will control the solenoid valve to close on that side and open on the other side. The material will flow to the empty material bucket on the other side. The staff only needs to replace the full material bucket, which saves manpower to a certain extent, and the procurement and maintenance costs are also lower. Moreover, it can also achieve more automated continuous operation.

[0016] 3. Compared to human eyes judging whether the material hopper is full or robotic arms or buffer rollers changing the hopper according to a set time, weight sensors can more accurately reflect whether the material in the hopper has reached the preset value. They are less susceptible to interference and misjudgment, so the weight of the filled material can be kept more consistent, thus better ensuring the reliability and stability of product indicators.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] The following is based on Figures 1 to 3 The technical solution of this application will be explained in detail.

[0026] The embodiments provided in this application relate to a material filling device, including a conveying pipe 10, a three-way reversing valve 20, a material hopper 30, a weight sensor 40, and a controller 50; the conveying pipe 10 includes an inlet pipe 11 and two outlet pipes 12; the three-way reversing valve 20 has an inlet 21 and two outlets 22, the inlet 21 is connected to the inlet pipe 11, and the two outlets 22 are detachably connected to their respective outlet pipes 12; the material hopper 30 includes two hoppers, each disposed on a corresponding outlet pipe 12. One side of the 2 is used to hold the material flowing out from the discharge pipe 12; the weight sensor 40 is located below the material bucket 30 and is used to detect the mass of the material bucket 30 in real time; the three-way reversing valve 20 is a solenoid valve; the weight sensor 40 is electrically connected to the controller 50; the controller 50 is electrically connected to the solenoid valve; in the working state, the feed port 21 and the feed pipe 11 are kept in communication; one discharge port 22 is connected to the corresponding discharge pipe 12; and the other discharge pipe 12 is closed to the corresponding discharge port 22.

[0027] Specifically, the conveying pipeline 10 includes an inlet pipe 11 and an outlet pipe 12. One end of the inlet pipe 11 is connected to a storage tank, and the other end is connected to the inlet 21 of a three-way directional valve 20. The material flows out of the storage tank and into the inlet pipe 11, and then flows to the inlet 21 of the three-way directional valve 20. The three-way directional valve 20 has two outlets 22, referred to as the first outlet and the second outlet, respectively. The first outlet and the second outlet are detachably connected to the outlet pipe 12, referred to as the first branch pipe and the second branch pipe. The first outlet is connected to the first branch pipe, and the second outlet is connected to the second branch pipe. The connection method can be threaded connection, snap-fit ​​connection, etc. When the material flows from the discharge port 22 to the three-way reversing valve 20, it cannot flow to the first discharge port and the second discharge port at the same time. The three-way reversing valve 20 is equipped with a valve core, which can block or close one of the discharge ports 22, while the other discharge port 22 is connected to the corresponding discharge pipe 12. At this time, the material can flow into the valve to the corresponding discharge pipe 12.

[0028] A material hopper 30 is provided on one side of both the first and second branch pipes. These two material hoppers 30 can be referred to as the first material hopper and the second material hopper, respectively. The first material hopper is located on one side of the first branch pipe, and the second material hopper is located on the other side of the second branch pipe. A weight sensor 40 is installed below each of the two material hoppers 30. The weight sensor 40 can detect the current mass of the material hopper 30 and the total mass of the material inside it in real time. The weight sensor 40 is electrically connected to the controller 50. The three-way reversing valve 20 is a solenoid valve and is also electrically connected to the controller 50. The controller 50, as the core control unit, can receive the transmission signal from the weight sensor 40 in real time and can drive the solenoid valve to reverse.

[0029] The working process is as follows: the feed inlet 21 and the feed pipe 11 are kept connected, the first discharge port and the first branch pipe are connected, and the second discharge pipe and the second branch pipe are not connected. The material flows from the feed pipe 11 through the first discharge port 22 and from the first branch pipe to the first material bucket. When the weight sensor 40 detects that the weight of the first material bucket has reached the preset value, the weight sensor 40 sends a signal to the controller 50. The controller 50 drives the first branch pipe and the first discharge port to close, and the second branch pipe and the second discharge port are connected. The material flows through the second discharge port and from the second branch pipe to the second material bucket. During the process of the material flowing through the second discharge port and from the second branch pipe to the second material bucket, the operator needs to replace the first material bucket that has been filled with material with an empty first material bucket. When the weight of the second material bucket reaches the preset value, the empty first material bucket begins to be filled, thus achieving non-stop operation.

[0030] Therefore, by setting up the solenoid valve, material filling can achieve continuous non-stop operation. Since the controller 50 and the solenoid valve can automatically change the opening and closing state of the valve, the staff does not need to manually open and close the valve. The staff only needs to replace the material bucket 30, which saves manpower to a certain extent, increases filling efficiency, does not cause too much damage to the filling equipment, extends the subsequent maintenance and service cycle, and has lower procurement and operation and maintenance costs.

[0031] Furthermore, compared to human eyes judging whether the material hopper 30 is full or the robotic arm or buffer roller conveyor replacing the material hopper 30 according to the set time, the weight sensor 40 can more accurately reflect whether the material in the material hopper 30 has reached the preset value. It is less susceptible to interference and misjudgment, so the weight of the filled material can be kept consistent, thus better ensuring the reliability and stability of product indicators.

[0032] In one embodiment, the material filling equipment further includes a lifting platform 60, on which the material hopper 30 and the weight sensor 40 are placed.

[0033] Specifically, the material filling system also includes a lifting platform 60, which can be lifted and lowered by a motor, a cylinder, or manually, making it more convenient for staff to change and move the material buckets 30.

[0034] In one embodiment, the lifting platform 60 includes a motor, a horizontal carrier plate 61, and a lifting mechanism 62. The material bucket 30 and the weight sensor 40 are placed on the horizontal carrier plate 61, the horizontal carrier plate 61 is disposed on the lifting mechanism 62, and the motor drives the lifting mechanism 62 to move up and down.

[0035] Specifically, the weight sensor 40 is placed on the horizontal carrier plate 61 and in direct contact with it. The horizontal carrier plate 61 is a support platform of arbitrary shape and is made of high-strength, high-load-bearing materials such as aluminum alloy or stainless steel. It can support the weight of the material bucket 30, the weight sensor 40, and the material inside the material bucket 30. The horizontal carrier plate 61 is connected to the lifting mechanism 62. When the motor drives the lifting mechanism 62 to move, the horizontal carrier plate 61 also moves up and down with the lifting mechanism 62, thereby realizing the up and down movement of the material bucket 30 within a certain range.

[0036] Thus, the motor drives the lifting mechanism 62 to move the horizontal carrier plate 61 vertically, thereby adjusting the position of the material barrel 30. The horizontal carrier plate 61, as the core bearing component, directly bears the weight of the material barrel 30 and the weight sensor 40 and provides a support platform to ensure the safety and stability of the filling process.

[0037] In one embodiment, the lifting mechanism 62 includes a base 621, a lead screw 622, a nut 623, a guide rod 624, a first connecting rod 625, and a second connecting rod 626. The lead screw 622 is mounted on the base 621 and connected to the output end of the motor. The nut 623 is sleeved on the outer periphery of the lead screw 622. The guide rod 624 and the nut 623 are fixedly connected. One end of the first connecting rod 625 is rotatably connected to the guide rod 624, and the other end of the first connecting rod 625 is rotatably connected to one side of the horizontal carrier plate 61. The other side of the horizontal carrier plate 61 is provided with a sliding groove 611. One end of the second connecting rod 626 is rotatably mounted on the base 621, and the other end of the second connecting rod 626 is rotatably mounted on the sliding groove 611, so that the end of the second connecting rod 626 slides along the sliding groove 611.

[0038] Specifically, the lead screw 622 is mounted on the base 621, and one side of the lead screw 622 is connected to the output end of the motor. The motor can drive the lead screw 622 to rotate. The nut 623 is sleeved on the lead screw 622, and the nut 623 has many threads inside that match the lead screw 622. It can be understood that the pitch of the internal thread of the nut 623 and the external thread on the lead screw 622 are matched to form a helical pair. When the lead screw 622 rotates, the nut 623 can translate along the axial direction of the lead screw 622.

[0039] Nut 623 and guide rod 624 are fixedly connected. The translation of nut 623 can drive guide rod 624 to translate axially along lead screw 622. Since one end of first connecting rod 625 is rotatably connected to guide rod 624, and the other end of first connecting rod 625 is rotatably connected to one side of horizontal carrier plate 61, when guide rod 624 translates axially along lead screw 622, one end of first connecting rod 625 will also move, thus changing the tilt angle of first connecting rod 625. The other side of horizontal carrier plate 61 is provided with slide groove 611. One end of second connecting rod 626 is installed in slide groove 611, and second connecting rod 626 can also slide horizontally along slide groove 611. The other side of second connecting rod 626 is installed on base 621 and can rotate around fixed point of base 621. When the first link 625 changes its tilt angle as the guide rod 624 moves horizontally, the first link 625 drives the second link 626 to rotate around the fixed point of the base 621. At the same time, the second link 626 can slide in the slide groove 611, so that the first link 625 and the second link 626 together drive the horizontal carrier plate 61 to rise or fall, and the two ends of the horizontal carrier plate 61 remain on the same horizontal plane.

[0040] Therefore, the horizontal carrier plate 61 can rise and fall stably, making it convenient for staff to use.

[0041] In one embodiment, there are two first connecting rods 625 and two second connecting rods 626. One end of each of the two first connecting rods 625 is rotatably connected to both ends of the guide rod 624, and the other end of each of the two first connecting rods 625 is rotatably connected to two positions on the same side of the horizontal carrier plate 61. The other side of the horizontal carrier plate 61 is provided with two spaced grooves 611. One end of each of the two second connecting rods 626 is rotatably mounted on two positions on the base 621, and the other end of each of the two second connecting rods 626 is respectively mounted in the two grooves 611. Each first connecting rod 625 and its corresponding second connecting rod 626 intersect and are rotatably connected at the intersection by a pin.

[0042] Specifically, there are two of each of the first link 625 and the second link 626. One first link 625 and one second link 626 are in the same group. The first link 625 and the second link 626 in this group are arranged crosswise and are hinged at the intersection by a pin. In this way, the first link 625 and the second link 626 can rotate around the hinge. The first link 625 is rotatably connected to one end of the guide rod 624, and the other end of the first link 625 is rotatably connected to the horizontal carrier plate 61. One end of the second link 626 is rotatably connected to the base 621.

[0043] Since the second link 626 and the first link 625 have the same length and their midpoints intersect, and the intersection is a hinge point, the first link 625 and the second link 626 have opposite tilt directions but the same tilt angle. When the first link 625 changes its tilt direction with the horizontal movement of the guide rod 624, the first link 625 drives the second link 626 to rotate around the fixed point of the base 621. At the same time, the second link 626 can slide in the slide groove 611. At this time, the horizontal carrier plate 61 reaches the required height. The first link 625 remains fixed, and one end of the second link 626 will also remain fixed in the slide groove 611.

[0044] The horizontal carrier plate 61 is provided with two sliding grooves 611. The first connecting rod 625 and the second connecting rod 626 mentioned above are a group and are distributed on one side of the base 621 and the horizontal carrier plate 61. The other group of first connecting rods 625 and second connecting rods 626 are also arranged as above and are distributed on the other side of the base 621 and the horizontal carrier plate 61.

[0045] Since the first link 625 and the second link 626 are rotatably connected, when the tilt angle of the first link 625 changes, it will also cause the end of the second link 626 to slide in the slide groove 611, ensuring the stability of the horizontal plate 61. This allows the horizontal plate 61 to maintain a relatively horizontal state when it goes up or down, preventing large tilting. Furthermore, the layout of the two sets of cross links and the guiding constraint of the slide groove 611 effectively prevent the horizontal plate 61 from tilting or twisting due to unilateral force. As a result, the stability of the lifting mechanism 62 is stronger, allowing the horizontal plate 61 to rise and fall smoothly and horizontally.

[0046] In one embodiment, the discharge pipe 12 is a rigid pipe and the end of the discharge pipe 12 is located above the inlet of the material barrel 30.

[0047] Specifically, in Figure 2 In the embodiment shown, the end of the discharge pipe 12 is located above the inlet of the material barrel 30 and there is a small gap between the discharge pipe 12 and the material barrel 30. The discharge pipe 12 is made of a relatively hard material, which can ensure that the discharge pipe 12 does not shift or shake when the material is transported in the discharge pipe 12 or when there is external vibration, and can correspond to the position of the material barrel 30.

[0048] Therefore, this design is more flexible, so that the shape and height of the opening of the material bucket 30 do not need to match the discharge pipe 12. It is only necessary to ensure that the size of the opening of the material bucket 30 is slightly larger than the size of the opening of the discharge pipe 12. This also prevents the discharge pipe 12 and the material bucket 30 from sticking together, making it easier to clean and replace the material bucket 30.

[0049] In another embodiment, the end of the discharge pipe 12 and the material bucket 30 are detachably connected.

[0050] Specifically, the end of the discharge pipe 12 can be threaded or snapped to the material barrel 30 to prevent material from falling out or splashing during the filling process.

[0051] In another embodiment, the end of the discharge pipe 12 is placed inside the material bucket 30.

[0052] Specifically, the end of the discharge pipe 12 is inserted into the material bucket 30, which is more suitable for filling liquids or materials containing particles. This not only prevents materials from splashing out and causing waste, but also better protects the particles and prevents them from hitting the bucket wall and breaking.

[0053] In one embodiment, the weight sensor 40 is provided with a display screen 41 for displaying real-time data.

[0054] Specifically, the display screen 41 is used to display the weight, date, or material information of the material bucket 30 in real time, so that staff can directly see the data and understand the filling situation.

[0055] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
