Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a packaging machine. Background Art

[0002] The last step in PVC stabilizer production is packaging. However, most PVC stabilizers have powder agglomeration, so they need to be stirred and broken up. In addition, the amount of powder collected cannot be controlled when the powder is packaged and collected.

[0003] For example, a packaging machine with publication number CN219468065U utilizes a stirring assembly, a screening assembly, and a reflux assembly to ensure that stabilizer packaging does not clump. By installing torsion springs and connecting plates on both sides of the packaging box, combined with inclined troughs and slide rails, the weight of the product falling into the box is utilized to separate the box from the slide rails, completing the quantitative collection and packaging of the product. However, installing torsion springs and connecting plates on both sides of each box significantly increases packaging costs and is not conducive to mass production. Therefore, a packaging machine is proposed to improve this. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] Therefore, one purpose of the present invention is to provide a packaging machine to solve the problems mentioned in the background technology and overcome the deficiencies in the prior art.

[0006] In order to achieve the above-mentioned object, an embodiment of one aspect of the present invention provides a packaging machine, comprising a chassis, a feed hopper is provided on the top of the chassis, a stirring box is provided in the chassis, a stirring assembly is provided in the stirring box, a filter assembly is provided at the bottom of the stirring box, a reflux assembly is provided at one end of the filter assembly, a discharge pipe is provided on the bottom surface of the filter assembly, a metering roller is rotatably connected to the discharge pipe, and a plurality of metering grooves are provided on the metering roller;

[0007] A support frame is fixedly connected to the chassis, a support rod is fixedly connected to the support frame, the end of the support rod is rotatably connected to a support block, a spring is provided between the support block and the support frame, a packaging box is overlapped on the support block, the rear end of the chassis is fixedly connected to an inclined rail extending to the support frame, and a conveyor belt is provided under the chassis.

[0008] Preferably, any of the above schemes is provided with a control panel on the front of the chassis, and the stirring assembly includes a stirring column and a stirring plate arranged in the stirring box, and a stirring motor fixedly connected to the stirring column.

[0009] Preferably, from any of the above schemes, the filter assembly is connected to the stirring tank via a connecting pipe, and a filter screen is provided in the middle of the bottom surface of the filter assembly.

[0010] With this technical solution, the chassis provides a mounting platform and workspace for the relevant components, protecting them from accidental damage from external components. A feed hopper is located on top of the chassis to add packaged raw materials. The mixing box and the stirring assembly agitate the product to prevent clumping. The stirring motor drives the stirring column, which in turn drives the stirring plate to stir the product. The agitated product then flows downward into the filter assembly, where it is filtered by the filter screen.

[0011] Preferably, from any of the above schemes, the reflux assembly includes a reflux box whose top is connected to the stirring box, and a reflux auger and a reflux motor arranged in the reflux box.

[0012] Preferably, any of the above schemes is provided with a motor on one side of the discharge pipe, the output shaft of which is fixedly connected to the metering roller, and a plurality of the metering grooves are evenly arranged on the metering roller.

[0013] Using this technical solution, products that meet the required particle size pass through the filter and enter the discharge pipe for discharge. Products that do not meet the particle size requirement flow into the return assembly, are conveyed by the return auger, and then enter the mixing tank again. They are mixed again by the mixing assembly and then enter the filter assembly again. This process is repeated until the required particle size is achieved. The metering roller rotates within the discharge pipe driven by a motor. The feeding interval can be adjusted by controlling the motor speed to prevent product from falling out when changing packaging boxes, which may cause problems in subsequent product collection.

[0014] Preferably, any of the above solutions has a notch on the inner side of the support frame, and the support block has a triangular structure.

[0015] Preferably, any of the above schemes is provided with a restraining groove in the middle of the inclined rail and a plurality of balls are arranged in the restraining groove, and a buffer pad is provided on the conveyor belt.

[0016] The above technical solution uses a support frame to support the support rod, which in turn supports the support block. The two are rotatably connected, allowing the support block to rotate to a certain extent. A spring supports the support block, ensuring it remains perpendicular to the support rod when no strong external force is applied. This allows the support block to support the packaging box, positioning it below the discharge pipe for receiving materials. When the box contains a sufficient amount of product, gravity pushes down on the support block, squeezing the spring and causing it to rotate. The box loses its support and falls onto the conveyor belt.

[0017] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0018] 1. This packaging machine utilizes a support frame, support rods, support blocks, springs, a packaging box, and an inclined rail. During packaging, products meeting the required particle size fall into a discharge pipe. A motor drives the metering roller, causing the product to flow out in a fixed amount and fall into the packaging box. When the box contains a sufficient amount of product, gravity pushes down on the support block, which compresses the spring and rotates, freeing the box from its support and dropping onto the conveyor. This eliminates the need for additional structural elements on the packaging box, significantly reducing packaging costs and facilitating mass production.

[0019] 2. This packaging machine features a discharge tube, dosing roller, and dosing trough. The dosing roller rotates within the discharge tube driven by a motor. The motor speed can be controlled to adjust the feeding interval, preventing product from falling during box changes and causing problems with subsequent product collection. Ball bearings installed within the ramp effectively reduce friction between the box and the ramp, improving smoothness during box changes. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] like Figures 1 to 5 As shown, the present invention provides a packaging machine, including a chassis 1, a feed hopper 2 is provided on the top of the chassis 1, a mixing box 3 is provided in the chassis 1, a mixing assembly 4 is provided in the mixing box 3, a filter assembly 5 is provided at the bottom of the mixing box 3, a reflux assembly 6 is provided at one end of the filter assembly 5, a discharge pipe 7 is provided on the bottom surface of the filter assembly 5, a metering roller 8 is rotatably connected to the discharge pipe 7, and a plurality of metering grooves 9 are opened on the metering roller 8;

[0030] A support frame 10 is fixedly connected to the chassis 1, a support rod 11 is fixedly connected to the support frame 10, the end of the support rod 11 is rotatably connected to a support block 12, a spring 13 is provided between the support block 12 and the support frame 10, a packaging box 14 is overlapped on the support block 12, the rear end of the chassis 1 is fixedly connected to an inclined rail 15 extending to the support frame 10, and a conveyor belt 16 is provided under the chassis 1.

[0031] Example 1: A control panel is provided on the front of the chassis 1, and the stirring assembly 4 includes a stirring column, a stirring plate and a stirring motor fixedly connected to the stirring column arranged in the stirring box 3. The filter assembly 5 is connected to the stirring box 3 through a connecting pipe, and a filter screen is provided in the middle of the bottom surface of the filter assembly 5. The chassis 1 provides an installation platform and working space for related structures, and provides protection for them to avoid damage caused by accidental collision with external structures. A feed hopper 2 is provided on the top of the chassis 1 to add packaged raw materials into the chassis 1. The stirring box 3 cooperates with the stirring assembly 4 to stir the product to prevent the product from agglomerating. The stirring motor drives the stirring column to rotate, and the stirring column drives the stirring plate to rotate to stir the product. The stirred product continues to move downward and flows into the filter assembly 5, and is filtered by the filter screen in the filter assembly 5.

[0032] Example 2: The reflux component 6 includes a reflux box connected to the mixing box 3 at the top, and a reflux auger and a reflux motor arranged in the reflux box. A motor with an output shaft fixedly connected to the metering roller 8 is provided on one side of the discharge pipe 7, and a number of metering slots 9 are evenly arranged on the metering roller 8. Products that meet the particle size requirements enter the discharge pipe 7 through the filter screen for discharge, and products that do not meet the particle size requirements flow into the reflux component 6, enter the mixing box 3 again after being transported by the reflux auger, are stirred for the second time by the mixing component 4, and then enter the filter component 5 again, and repeat this process until the particle size requirements are met. The metering roller 8 rotates in the discharge pipe 7 driven by the motor, and the feeding interval can be adjusted by controlling the speed of the motor to avoid the problem of product collection in the later stage caused by the empty product when the packaging box is replaced.

[0033] Example 3: A notch is provided on the inner side of the support frame 10, and the support block 12 adopts a triangular structure. A constraint groove is provided in the middle of the inclined rail 15, and a plurality of ball bearings are provided in the constraint groove, and a buffer pad is provided on the conveyor belt 16. The support frame 10 is used to support the support rod 11, and the support rod 11 supports the support block 12. The two are rotatably connected so that the support block 12 can rotate to a certain extent. The spring 13 supports the support block 12 so that the support block 12 remains perpendicular to the support rod 11 when there is no strong external force. Then, the support block 12 can be used to support the packaging box 14 so that the packaging box 14 is located below the discharge pipe 7 for receiving materials. When there is a sufficient amount of product in the packaging box 14, gravity presses the support block 12 downward, and the support block 12 squeezes the spring 13 and rotates. The packaging box 14 loses support and falls onto the conveyor belt 16.

[0034] The working principle of this utility model is as follows:

[0035] S1. Pour the product into the feed hopper 2, and the product falls into the mixing box 3 through the feed hopper 2. The mixing component 4 stirs the product, and then the product flows into the filtering component 5. The product that meets the particle size requirements passes through the filter and enters the discharge pipe 7 for discharge. The product that does not meet the particle size requirements flows into the reflux component 6, is transported by the reflux auger, and then enters the mixing box 3 again. It is stirred for the second time by the stirring component 4 and then enters the filtering component 5 again. This process is repeated until the particle size requirements are met.

[0036] S2, the metering roller 8 is driven by the motor to rotate in the discharge pipe 7, so that the product flows out at a certain interval. The outflowing product falls into the packaging box 14;

[0037] S3. When there is enough product in the packaging box 14, gravity presses down the support block 12, which squeezes the spring 13 and rotates. The packaging box 14 loses its support and falls onto the conveyor belt 16. The subsequent packaging box 14 flows through the inclined rail 15 to the bottom of the discharge pipe 7 and continues to be packaged.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. This packaging machine, comprising a support frame 10, support rods 11, support blocks 12, springs 13, a packaging box 14, and ramps 15, allows products meeting the required particle size to fall into a discharge pipe 7 during packaging. A metering roller 8, driven by a motor, rotates, causing a predetermined amount of product to flow out and fall into packaging box 14. When a sufficient amount of product is present in packaging box 14, gravity presses down on support block 12, which compresses spring 13 and rotates, freeing packaging box 14 from support and dropping onto conveyor belt 16. This eliminates the need for additional components on packaging box 14, significantly reducing its cost and facilitating mass production.

[0040] 2. This packaging machine incorporates a discharge pipe 7, a metering roller 8, and a metering trough 9. Driven by a motor, the metering roller 8 rotates within the discharge pipe 7. The motor's speed can be controlled to adjust the feeding interval, preventing product from falling during box replacement, which could cause problems with subsequent product collection. Ball bearings are incorporated into the ramp 15 to effectively reduce friction between the box 14 and the ramp, improving smoothness during box replacement.
