Description

Technical Field

[0001] This application relates to the field of packaging machine technology, and in particular to an automatic packaging machine. Background Technology

[0002] A dispensing machine is a mechanical device used to quantitatively distribute materials into containers. In the production process of pet nutritional supplements, which are usually in powder form, a dispensing machine is needed to dispense the powder into dispensing bottles after the powder mixing process is completed.

[0003] For example, utility model patent CN202987538U discloses a screw-type powder dispensing machine, which includes a bracket, a motor, a powder hopper, a dispensing screw, and a threaded component. The powder hopper is fixed to the bracket with bolts, the dispensing screw is connected to the motor via a drive shaft, and the threaded component is integrally fixed to the end of the dispensing screw away from the motor, and the threaded component matches the powder hopper. When the operator uses the dispensing machine, the operator pours the powder into the powder hopper, then places the dispensing bottle below the discharge port of the powder hopper, aligning the bottle opening with the discharge port. At this time, the motor is started, causing the dispensing screw to rotate. The rotation of the threaded component causes the powder in the powder hopper to fall into the dispensing bottle through the discharge port, thus realizing the powder dispensing process.

[0004] When the powder is packaged in large quantities, the repeated action of changing packaging bottles for a long time causes physical fatigue among the staff, making it difficult to align the bottle opening with the discharge port. This causes the powder to slip out of the packaging bottle, resulting in powder waste, which is an area that needs improvement. Utility Model Content

[0005] When powder is being packaged in large quantities, in order to align the bottle opening with the discharge port and reduce the probability of powder slipping out of the bottle, thereby reducing powder waste, this application provides an automatic packaging machine.

[0006] This application provides an automatic packaging machine, which adopts the following technical solution:

[0007] An automatic dispensing machine includes a machine body, a feeding mechanism disposed on the machine body, a frame fixed to the side wall of the machine body, and a conveyor mounted on the frame. The conveyor is disposed on the frame, and the side of the conveyor away from the ground is used to place dispensing bottles. A limiting mechanism for limiting the relative position of the dispensing bottles in the width direction of the frame is fixed on the frame. A driving member for driving the conveyor is installed on the side wall of the frame.

[0008] By adopting the above technical solution, when the operator uses the automatic dispensing machine, the operator places the dispensing bottles sequentially above the conveyor. At this time, the drive unit drives the conveyor to move, and the conveyor moves the dispensing bottles. Under the limiting action of the limiting mechanism, the dispensing bottles slide to below the discharge port. When the dispensing bottle is below the discharge port of the funnel, the powder falls into the interior of the dispensing bottle through the discharge port of the discharge mechanism. Then, the conveyor transports the dispensing bottle filled with powder to a position away from the machine body. The operator puts the bottle cap on the bottle mouth and places an empty dispensing bottle above the conveyor again, repeating the above process. This setting aligns the bottle mouth with the discharge port, reducing the probability of powder sliding out of the dispensing bottle, thereby reducing powder waste.

[0009] Optionally, the limiting mechanism includes limiting plates disposed on both sides of the frame, the limiting plates being disposed along the length of the frame, the limiting plates being located above the conveying component, and both limiting plates being close to the dispensing bottles.

[0010] By adopting the above technical solution, when the conveyor moves the dispensing bottle, a passage is formed between the two limiting plates. The setting of the two limiting plates restricts the sliding of the dispensing bottle in the width direction of the frame, reducing the possibility that the dispensing bottle will deviate during the sliding process, thereby causing the powder to slide out of the dispensing bottle.

[0011] Optionally, the limiting mechanism further includes a limiting rod fixed to the side of the limiting plate away from the other limiting plate, and a limiting clamp fixed to the side of the frame away from the ground, the limiting clamp holding and fixing the limiting rod.

[0012] By adopting the above technical solution, when the model of the dispensing bottle changes, the staff can change the position of the limiting plate by changing the position of the limiting clamp holding the limiting rod, thereby realizing the limiting function of the limiting plate for different models of dispensing bottles.

[0013] Optionally, a blocking plate is fixed to the end of the limiting plate, and the blocking plate is inclined in a direction away from the other limiting plate.

[0014] By adopting the above technical solution, when the staff places the dispensing bottle on the conveyor, the conveyor drives the dispensing bottle to slide towards the discharge port. At this time, the dispensing bottle is close to the limiting plate. When the dispensing bottle is not in the same straight line as the discharge port in the length direction of the frame, the dispensing bottle slides into the position between the two limiting plates under the action of the blocking plate, reducing the possibility of errors in the dispensing bottle filling process.

[0015] Optionally, both ends of the limiting rod are fixed with the blocking plate.

[0016] By adopting the above technical solution, when the conveying direction of the conveyor changes, the setting of the baffle plate can reduce the possibility of errors in the dispensing bottle filling process at both ends of the conveyor.

[0017] Optionally, a position sensor is provided on the frame to detect the position of the dispensing bottle and output a position detection signal. The machine body is provided with a control component, which is electrically connected to the position sensor, the feeding mechanism, and the drive component. The control component receives and responds to the position detection signal to control the movement of the feeding mechanism and the drive component. When the dispensing bottle is located below the feeding port, the position sensor outputs a position detection signal, and the control component receives and controls the movement of the drive component based on the position detection signal.

[0018] By adopting the above technical solution, when the dispensing bottle is located below the discharge port, the position sensor detects the position of the dispensing bottle and outputs a position detection signal. At this time, the controller receives the signal and controls the drive to stop based on the position detection signal. The controller also controls the dispensing mechanism to move, and the powder falls into the dispensing bottle through the discharge port. This setting further improves the automation of the dispensing bottle feeding process and reduces manpower consumption.

[0019] Optionally, a linear module is fixed on the machine body, the linear module is electrically connected to the control component, and the unloading mechanism includes a fixed frame and a funnel that are fixed to each other. The funnel is located below the fixed frame, and the fixed frame is fixed to the slide table of the linear module.

[0020] By adopting the above technical solution, when the bottle type changes, the operator can change the height of the fixing frame on the side wall of the machine body through the linear module, thereby changing the relative position of the funnel on the side wall of the machine body, so that the distance between the discharge port and the bottle mouth of the dispensing bottle can be adjusted, thus allowing the powder to fall stably into the interior of the dispensing bottle.

[0021] Optionally, a height sensor is provided on the machine body. The height sensor is used to detect the height of the dispensing bottle and output a height detection signal. The height sensor is electrically connected to the control component. The control component receives and responds to the height detection signal to control the operation of the linear module. When the dispensing bottle is below the discharge port, the height sensor outputs a height detection signal, and the control component receives and controls the operation of the linear module based on the height detection signal.

[0022] By adopting the above technical solution, when the dispensing bottle is located below the discharge port, the height sensor detects the height of the dispensing bottle and outputs a height detection signal. At this time, the controller receives the signal and controls the linear module to move based on the height detection signal. The linear module drives the fixed frame to slide, that is, the funnel slides relative to the machine body. When the height of the funnel meets the discharge requirements, the controller controls the linear module to stop moving. This setting allows the linear module to change the height of the funnel when the dispensing bottle type changes, so as to meet the discharge requirements of the dispensing bottle.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the operator uses the automatic dispensing machine, the operator places the dispensing bottle on the conveyor. The drive unit then moves the dispensing bottle towards the discharge port. Under the limiting action of the limiting mechanism, the dispensing bottle slides accurately towards the discharge port. When the dispensing bottle is below the discharge port, the operator uses the discharge mechanism to make the powder slide out of the discharge port and fall into the interior of the dispensing bottle. The drive unit continues to move the dispensing bottle. The operator then puts the bottle cap on the bottle opening. This setting aligns the bottle opening with the discharge port, reducing the probability of powder sliding out of the dispensing bottle and thus reducing powder waste.

[0025] 2. Before using the automatic dispensing machine, the staff adjusts the relative position of the limiting rod on the limiting clamp according to the model of the dispensing bottle, so that the distance between the two limiting plates meets the diameter requirements of the dispensing bottle, thereby reducing the possibility that the dispensing bottle and the discharge port cannot be aligned.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses an automatic packaging machine.

[0032] Reference Figure 1 An automatic dispensing machine includes a body 1, a feeding mechanism 2, a frame 3, a conveyor 4 mounted on the frame 3, and a limiting mechanism 5 fixed on the frame 3. The frame 3 is fixed to the body 1 by bolts. The feeding mechanism 2 is used to store and quantitatively dispense powder. The frame 3 is located below the feeding port of the feeding mechanism 2. In this embodiment, the frame 3 has support frames 11 fixed at both ends along its length direction, which abut against the ground. The conveyor 4 is preferably a conveyor belt, which is wound around the frame 3. The limiting mechanism 5 is used to limit the relative position of the dispensing bottles in the width direction of the frame 3. The frame 3 is fixed with a drive member 6 for driving the conveyor 4 to rotate. The drive member 6 is preferably a rotating shaft, which is located at both ends of the frame 3. The conveyor 4 is wound around the two drive members 6.

[0033] When the staff uses the automatic dispensing machine to dispense powder, they place empty dispensing bottles at intervals on the conveyor 4. At this time, the drive component 6 is activated, causing the rotating component to rotate. The rotating component causes the empty dispensing bottles to slide towards the discharge port. Under the limiting action of the limiting mechanism 5, the dispensing bottles and the discharge port are on the same straight line along the length of the frame 3. When the dispensing bottle is below the discharge port, the drive component 6 is stopped and the discharge mechanism 2 is activated. When the dispensing bottle is filled with powder, the staff activates the drive component 6 to move the filled dispensing bottle away from the discharge port and puts the cap on the bottle mouth, so that the next empty dispensing bottle is below the discharge port.

[0034] Reference Figure 2 The limiting mechanism 5 includes limiting clamps 53 fixed to both sides of the frame 3 by bolts, limiting rods 52 clamped and fixed to the limiting clamps 53, and limiting plates 51 fixed to the ends of the limiting rods 52. There are four limiting clamps 53, two of which are located on one side of the frame 3 and the other two are located on the other side of the frame 3. All four limiting clamps 53 are clamped and fixed to the limiting rods 52. The limiting plates 51 are fixed to the ends of two adjacent limiting rods 52 in the length direction of the frame 3. The length of the limiting plates 51 is greater than the distance between two adjacent limiting clamps 53. Both limiting plates 51 are located in the length direction of the frame 3 and can approach the dispensing bottles.

[0035] Before the staff uses the automatic dispensing machine, the staff adjusts the relative position of the limiting rod 52 on the limiting clamp 53 according to the model of the dispensing bottle. That is, the distance between the two limiting plates 51 is adjusted by the limiting rod 52. At this time, when the conveyor 4 drives the dispensing bottle to slide between the two limiting plates 51, the dispensing bottle and the discharge port are in a straight line in the length direction of the frame 3, realizing the alignment of the opening position of the dispensing bottle with the opening position of the discharge port.

[0036] Reference Figure 2 The limiting mechanism 5 also includes a baffle plate 54 that is integrally fixed to both ends of the limiting plate 51. The baffle plate 54 has a curved panel structure and is inclined in the direction away from the other limiting plate 51. When the dispensing bottle is not in the same straight line as the discharge port in the length direction of the frame 3, the conveyor 4 drives the dispensing bottle to abut against the side wall of the baffle plate 54. Due to the inclined setting of the baffle plate 54, the dispensing bottle slides into the position between the two limiting plates 51 under the blocking action of the baffle plate 54, which facilitates the alignment process of the bottle mouth and the discharge port and increases the dispensing efficiency of powder.

[0037] Reference Figure 1 and Figure 3 It also includes a material feeding mechanism 2, which includes a fixed frame 21, a funnel 22, a drive motor 23, a screw 24, and a stirring rod 25. The funnel 22 is fixed to the lower part of the fixed frame 21 by bolts, and the drive motor 23 is fixed to the upper part of the fixed frame 21 by bolts. A connecting shell is bolted to the rotating shaft of the drive motor 23. The end of the connecting shell away from the drive motor 23 is fixed to the screw 24 by bolts. The stirring rod 25 is integrally fixed to both sides of the screw 24, and the stirring rod 25 abuts against the inner wall of the funnel 22. The end of the screw 24 away from the drive motor 23 is transitionally fitted with the material feeding port of the funnel 22. The end of the screw 24 away from the drive motor 23 is provided with an external thread, and the external thread of the screw 24 is located at the material feeding port of the funnel 22.

[0038] When the operator starts the automatic dispensing machine, the operator first pours the powder to be dispensed into the inside of the funnel 22. Then, the operator starts the drive motor 23, which drives the screw 24 to rotate. The screw 24 drives the stirring rod 25 to rotate, scraping off the powder adhering to the inner wall of the funnel 22. The powder in the funnel 22 slides out of the discharge port through the gap of the external thread of the rotating screw 24. Finally, the operator can control the rotation speed and number of revolutions of the screw 24 by adjusting the output power of the drive motor 23 and the opening and closing time, thereby achieving controllability of the material discharge from the funnel 22.

[0039] Reference Figure 1 and Figure 3 A linear module 9 is fixed to the side wall of the machine body 1. The linear module 9 is located on the machine body 1 at a position away from the ground. The fixing frame 21 is fixed to the slide of the linear module 9 with bolts. Before the staff uses the automatic dispensing machine for dispensing, the height of the funnel 22 needs to be adjusted according to the height of the dispensing bottle. At this time, the staff controls the lifting and lowering of the slide through the linear module 9, thereby directly controlling the relative position of the fixing frame 21 on the side wall of the machine body 1, thereby reducing the possibility that the discharge port of the funnel 22 is too close to or too far from the opening of the dispensing bottle.

[0040] Reference Figure 2 and Figure 3A position sensor 7 is bolted to the frame 3, which is aligned with the material inlet in the width direction. A height sensor 10 is bolted to the side of the body 1 near the frame 3. The height sensor 10 and the material inlet are aligned with the frame 3 in the width direction. Both the position sensor 7 and the height sensor 10 are preferably infrared sensors. A control component 8 is also bolted to the body 1. The control component 8 is located on the side wall of the body 1 and is electrically connected to the position sensor 7, the height sensor 10, the linear module 9, the drive component 6, and the drive motor 23.

[0041] When the operator uses the automatic dispensing machine, the operator places the dispensing bottle on the conveyor 4. At this time, the operator controls the drive unit 6 to start via the control unit 8. The drive unit 6 drives the conveyor 4 to move on the frame 3. The conveyor 4 moves the dispensing bottle towards the discharge port. When the dispensing bottle is below the discharge port, the position sensor 7 detects the dispensing bottle and outputs a position detection signal. The control unit 8 receives the position detection signal and controls the drive unit 6 to stop based on the position detection signal. At this time, the height sensor 10 detects the height of the dispensing bottle and outputs a height detection signal. The control unit 8 receives the height detection signal and controls the linear module 9 based on the height detection signal, so that the height of the funnel 22 on the side wall of the machine body 1 meets the height requirement of the dispensing bottle. At this time, the control unit 8 detects and controls the drive motor 23 to operate based on the new detection result of the height sensor 10. The powder falls into the dispensing bottle through the discharge port. Then, the control unit 8 controls the drive unit 6 to start again. The drive unit 6 moves the dispensing bottle filled with powder away from the discharge port, realizing the automatic dispensing process of powder.

[0042] The implementation principle of an automatic dispensing machine according to an embodiment of this application is as follows: When the operator uses the automatic dispensing machine, the operator pours the powder into the funnel 22, and then places the dispensing bottle above the conveyor 4. At this time, the controller 8 controls the drive 6 to start, and the drive 6 drives the conveyor 4 to slide on the frame 3. The conveyor 4 drives the dispensing bottle to slide towards the discharge port. When the dispensing bottle is below the discharge port, the position sensor 7 and the height sensor 10 output position detection signals and height detection signals respectively. The controller 8 receives and processes the position detection signals... The signal and height detection signals respectively control the drive unit 6 to stop and the funnel 22 to slide on the side wall of the machine body 1. Then, the control unit 8 controls the drive motor 23 to start, and the powder falls into the dispensing bottle through the discharge port. When the dispensing bottle is full of powder, the control unit 8 controls the drive unit 6 to start again. The drive unit 6 drives the conveyor 4 to slide on the frame 3. At this time, the dispensing bottle full of powder is away from the discharge port. The staff puts the bottle cap on the bottle mouth. This setting aligns the bottle mouth with the discharge port, reducing the probability of powder sliding out of the dispensing bottle, thereby reducing powder waste.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
