[0002] Conventional packing boxes are generally composed of multiple materials. During the production process, it is necessary to proportion and mix the production raw materials, which generally include at least two raw materials. The main raw materials are solid raw materials and liquid raw materials. During production, they are mixed in a certain proportion and then subjected to subsequent processing. Therefore, a special raw material proportioning and mixing device is required to meet the use requirements.

[0003] Conventional raw material proportioning and mixing devices mainly consist of a proportioning device and a mixing device. The proportioning device generally consists of multiple feed pipes and a weighing device. After feeding in proportion and weighing, it is discharged into the mixing device for mixing when the requirements are met. This kind of proportioning device needs to repeatedly add materials to the weighing device during actual proportioning, and cannot perform automatic feeding, resulting in low feeding efficiency.

[0004] Moreover, during batch proportioning and mixing, since the weighing tank needs to mix and weigh different materials, a certain amount of materials remains inside the weighing tank. In the prior art, the weighing tank needs to be cleaned regularly to meet the proportioning requirements. At the same time, during cleaning, the entire device is in a shutdown state, seriously affecting the mixing efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a raw material proportioning and mixing device and a mixing method for the production of packing boxes to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A raw material proportioning and mixing device for the production of packing boxes, including a frame. A proportioning component is fixedly sleeved at a position near the bottom end on the inner side surface of the frame. A plurality of batching tanks are fixedly installed at equal intervals axially near the top end on the inner side surface of the frame. The number of the batching tanks is not less than three. A machine base is fixedly installed between the batching tanks. An adjusting component is movably sleeved inside the machine base. One side of the adjusting component is fixedly installed with a weighing component located directly below the batching tank. Support legs are fixedly installed at equal intervals axially at the bottom end of the frame. A feeding pipe is fixedly communicated with one side of each batching tank. A three-way valve is fixedly communicated with the bottom end of the weighing component. A drain pipe is fixedly communicated with one side of the three-way valve.

[0007] Before raw material mixing and proportioning, different raw materials need to be respectively injected into the interiors of two batching tanks through the feeding pipes, and clear water is injected into the interior of another batching tank.

[0011] As a further technical solution of the present invention, the bottom end of the transmission shaft penetrates through the bottom end of the upper locking frame and is fixedly connected with a fixed pipe. An activity rod is movably clamped inside the fixed pipe. The activity rod moves up and down relative to the fixed pipe and cannot rotate relative to the fixed pipe. The bottom end of the activity rod is movably clamped with an activity rod. The activity rod is fixedly sleeved with the weighing component. The bottom end of the activity rod penetrates through the bottom end of the lower locking frame and is connected to the proportioning component.

[0012] As a further technical solution of the present invention, the activity rod rotates relative to the lower locking frame and cannot move up and down relative to the lower locking frame.

[0013] When proportioning and weighing are required, the main motor can be turned on to drive the adjusting component to rotate, and at the same time drive the weighing component to rotate circumferentially. When the weighing component rotates below any batching tank loaded with materials, the valve at the bottom end of the batching tank can be opened to release the materials into the inside of the weighing component. Until the proportional requirement is met, control the weighing component to continue to rotate circumferentially until it rotates below another batching tank, and open the bottom valve to complete the injection of another material.

[0016] As a further technical solution of the present invention, one side of the feed funnel is connected to the upper locking frame, a sealing cover plate located inside the weighing tank is fixedly installed at the bottom end of the feed funnel, a cleaning brush is fixedly sleeved on the outer side surface of the sealing cover plate, the outer side surface of the cleaning brush is in contact with the inner side surface of the weighing tank, a limiting plate is fixedly sleeved at a position near the top end of the feed funnel, a return spring is movably sleeved on the outer side surface of the feed funnel, and the upper and lower ends of the return spring are respectively connected to the bottom end of the limiting plate and the top end of the weighing tank.

[0017] When the return spring is in the initial state, the sealing cover plate and the cleaning brush are at the highest point inside the weighing tank, and the distance between the upper locking frame and the lower locking frame is the maximum value.

[0018] After adding two kinds of materials, the weighing assembly can be rotated to the lower part of the water preparation tank loaded with clear water, and the corresponding valve is opened to inject clear water into the inside of the feed funnel. At this time, the clear water enters the inside of the weighing tank accordingly. At the same time, the electric push rod needs to be opened. At this time, the extension rod rises accordingly, and drives the lower locking frame to rise synchronously. At this time, the weighing tank moves upward accordingly, the distance between the weighing tank and the feed funnel decreases, the sealing cover plate moves downward relative to the weighing tank, and at this time, the inside of the weighing tank can be automatically cleaned in cooperation with the injected clear water. After the cleaning is completed, the valve on the side of the three-way valve can be opened, and the cleaning sewage can be discharged through the drain pipe to complete the self-cleaning process.

[0019] By reusing the cooperation of the adjustment assembly and the weighing assembly, the cooperation between the proportioning assembly and the weighing assembly, and cooperating with the pre-stored clear water, the device can automatically clean itself after completing one proportioning, without the need for regular cleaning, can perform continuous cleaning after completing the proportioning, and during the entire cleaning process, the device can be in a continuous mixing state, which will not affect the normal proportioning and mixing, and improves the mixing efficiency.

[0020] As a further technical solution of the present invention, the proportioning component includes a proportioning tank, the outer side surface of the proportioning tank is fixedly sleeved with the frame, the bottom end of the proportioning tank is fixedly communicated with a discharge valve, the top end of the discharge valve is movably connected with an extension shaft located inside the proportioning tank, the top end of the extension shaft is fixedly connected with a stirring shaft, the top end of the stirring shaft is fixedly connected with an electric push rod, a crushing needle is installed at the output end of the electric push rod, a middle part of the top end of the crushing needle is fixedly installed with an extension rod, the top end of the extension rod penetrates through the top end of the proportioning tank and is connected with a movable rod, and the top end of the proportioning tank is axially equidistantly provided with a feed port directly below the three-way valve.

[0021] After the proportioning is completed, the proportioned raw materials can be injected into the interior of the proportioning tank through the feed port, and the main motor can be started to drive the adjustment component to rotate and drive the extension rod to rotate. At this time, the extension shaft rotates accordingly, and drives the stirring shaft to rotate to mix the raw materials inside the proportioning tank.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] As Figures 1 to 7 shown, in the embodiment of the present invention, a raw material proportioning and mixing device for producing packing boxes includes a frame 1. A proportioning component 3 is fixedly sleeved at a position near the bottom of the inner side surface of the frame 1. A plurality of batching tanks 4 are fixedly installed at equal intervals along the axis at a position near the top of the inner side surface of the frame 1. The number of the batching tanks 4 is not less than three. A machine base 5 is fixedly installed between the batching tanks 4. An adjustment component 9 is movably sleeved inside the machine base 5. A weighing component 12 located directly below the batching tanks 4 is fixedly installed on one side of the adjustment component 9. Support legs 2 are fixedly installed at equal intervals along the axis at the bottom of the frame 1. One side of each batching tank 4 is fixedly communicated with an injection pipe 8. The bottom of the weighing component 12 is fixedly communicated with a three-way valve 10. One side of the three-way valve 10 is fixedly communicated with a drain pipe 11.

[0041] Before mixing and proportioning the raw materials, different raw materials need to be respectively injected into the interiors of two batching tanks 4 through the injection pipes 8, and clear water is injected into the interior of another batching tank 4. At the same time, the raw materials are kept in a molten state during injection to complete the preparation before mixing and proportioning.

[0042] As Figure 1 and Figure 4 shown, a locking seat 6 is fixedly installed at the top of the machine base 5. A main motor 7 is fixedly installed on the inner side surface of the locking seat 6. The output end of the main motor 7 is connected to the adjustment component 9.

[0043] When starting the proportioning, the main motor 7 can be turned on to drive the adjustment component 9 at the bottom to rotate. At this time, the adjustment component 9 rotates relative to the machine base 5, and drives the weighing component 12 on one side to rotate relative to the batching tank 4.

[0044] As Figure 1 and Figure 5 shown, the adjustment component 9 includes a transmission shaft 901, which is movably connected to the machine base 5. The transmission shaft 901 rotates relative to the machine base 5. The top end of the transmission shaft 901 is connected to the output end of the main motor 7. The bottom end of the transmission shaft 901 is movably clamped with an upper locking frame 902. The transmission shaft 901 rotates relative to the upper locking frame 902 and cannot move up and down relative to the upper locking frame 902.

The activity rod 905 rotates relative to the lower locking frame 903 and cannot move up and down relative to the lower locking frame 903.

[0045] Embodiment: When proportioning and weighing are required, the main motor 7 can be turned on to drive the adjustment component 9 to rotate, and at the same time drive the weighing component 12 to rotate circumferentially. When the weighing component 12 rotates to the lower part of any batching tank 4 loaded with materials, the valve at the bottom of the batching tank 4 can be opened to release the materials into the inside of the weighing component 12. Until the proportional requirement is met, control the weighing component 12 to continue to rotate circumferentially until it rotates to the lower part of another batching tank 4, and open the bottom valve to complete the injection of another material. After weighing by the weighing component 12, it is introduced into the proportioning component 3 through the weighing component 12 to complete the weighing and introduction process of the raw materials.

[0046] By utilizing the cooperation between multiple batching tanks 4, the adjustment component 9 and the weighing component 12, and through the continuously circumferentially rotating weighing component 12 cooperating with the batching tanks 4 at fixed positions, before proportioning, only the raw materials need to be filled up, and then continuous feeding operations can be carried out according to the proportion through the weighing component 12. There is no need to add materials repeatedly, and continuous automatic feeding can be realized. The whole feeding process is relatively fast and the feeding efficiency is high.

[0047] As Figure 1 and Figure 5 and Figure 6 and Figure 7As shown in the figure, the weighing assembly 12 includes a weighing tank 121. The outer side surface of the weighing tank 121 is fixedly sleeved between the lower locking frame 903.

A cleaning brush 127 is fixedly sleeved on the outer side surface of the sealing cover plate 126. The outer side surface of the cleaning brush 127 is in contact with the inner side surface of the weighing tank 121. A limiting plate 125 is fixedly sleeved at a position near the top end of the inlet funnel 124. A return spring 128 is movably sleeved on the outer side surface of the inlet funnel 124. The upper and lower ends of the return spring 128 are respectively connected to the bottom end of the limiting plate 125 and the top end of the weighing tank 121. When the return spring 128 is in the initial state, the sealing cover plate 126 and the cleaning brush 127 are located at the highest point inside the weighing tank 121, and the distance between the upper locking frame 902 and the lower locking frame 903 is the maximum value.

[0048] Embodiment: After adding two kinds of materials, the weighing assembly 12 can be rotated to the lower part of the water preparation tank 4 loaded with clean water, and the corresponding valve is opened to inject clean water into the inner part of the inlet funnel 124. At this time, the clean water enters the inner part of the weighing tank 121 accordingly. At the same time, the electric push rod 306 needs to be opened. At this time, the extension rod 307 rises accordingly and drives the lower locking frame 903 to rise synchronously. At this time, the weighing tank 121 moves upward accordingly, the distance between the weighing tank 121 and the inlet funnel 124 decreases accordingly, and the sealing cover plate 126 moves downward relative to the weighing tank 121 accordingly. At this time, the inner part of the weighing tank 121 can be automatically cleaned by cooperating with the injected clean water. After the cleaning is completed, the valve on the side of the three-way valve 10 can be opened, and the cleaning sewage can be discharged through the drain pipe 11 to complete the self-cleaning process.

[0049] By reusing the cooperation of the adjusting assembly 9 and the weighing assembly 12, as well as the cooperation between the proportioning assembly 3 and the weighing assembly 12, and cooperating with the pre-stored clean water, the device can automatically clean itself after completing one proportioning, without the need for regular cleaning, can perform continuous cleaning after completing the proportioning, and during the entire cleaning process, the device can be in a continuous mixing state, which will not affect the normal proportioning and mixing, and improves the mixing efficiency.

[0050] Such as Figure 1 and Figure 3As shown in the figure, the proportioning assembly 3 includes a proportioning tank 301. The outer side of the proportioning tank 301 is fixedly sleeved with the frame 1. The bottom end of the proportioning tank 301 is fixedly communicated with a discharge valve 302.

The top end of the extension shaft 303 is fixedly connected with a stirring shaft 305. The top end of the stirring shaft 305 is fixedly connected with an electric push rod 306. The output end of the electric push rod 306 is provided with a crushing needle 308. The middle part of the top end of the crushing needle 308 is fixedly installed with an extension rod 307. The top end of the extension rod 307 penetrates through the top end of the proportioning tank 301 and is connected with the movable rod 905. The top end of the proportioning tank 301 is axially and equidistantly provided with feed ports 304 located directly below the three-way valve 10.

[0051] After the proportioning is completed, the proportioned raw materials can be injected into the interior of the proportioning tank 301 through the feed ports 304. The main motor 7 can be started to drive the adjustment assembly 9 to rotate and drive the extension rod 307 to rotate. At this time, the extension shaft 303 rotates accordingly, driving the stirring shaft 305 to rotate, mixing the raw materials inside the proportioning tank 301. At the same time, when the self-cleaning of the weighing assembly 12 is carried out, the electric push rod 306 can be started to drive the extension rod 307 and the crushing needle 308 to rise, and the active rotation of the crushing needle 308 can be completed in cooperation with the rotation of the extension rod 307, actively crushing the raw materials to reduce agglomeration.

[0052] By reusing the cooperation between the proportioning assembly 3 and the weighing assembly 12, and using the active cleaning process and the raw material proportioning process, the device can complete the proportioning of raw materials and the mixing of raw materials at the same time. During the active cleaning, the automatic piercing of the agglomerated raw materials can be realized. The whole process can be completed in a linkage manner, further improving the overall mixing efficiency and the mixing quality.

[0053] A mixing method for a raw material proportioning and mixing device for producing packing boxes includes the following steps:

After reaching the requirements, open the valve at the bottom end of the three-way valve 10, and inject the proportionally mixed raw materials into the interior of the proportioning tank 301;

[0056] S3: Turn on the main motor 7 to drive the adjustment component 9 to rotate continuously, drive the extension rod 307 at the bottom to rotate, and at the same time drive the stirring shaft 305 to rotate to mix and proportion the raw materials.
