Description

Technical Field

[0001] The present invention relates to the technical field of feed packaging equipment, and particularly to a fish feed sub-packaging device. Background Art

[0002] Most current fish feeds are granular materials. Their production method usually uses a variety of powder materials as raw materials. After mixing the powders, they are granulated by a granulator to obtain granular fish feed. In the final link of fish feed production, it is necessary to sub-package the prepared fish feed. Two issues need to be noted during sub-packaging. One is the quantitative packaging. It is necessary to ensure the weight of the sub-packaged feed, and there should be no sub-packaging situation with a weight error exceeding the limit. This requires the sub-packaging device to supply materials according to the required weight. The second issue is the need to pay attention to the protection of the feed during the sub-packaging process. Because fish feed is granular material and the prepared fish feed particles are very dry. When using equipment for sub-packaging, it is easy for the particles to be crushed due to the movement of the mechanical components of the equipment, and it is also not in line with the requirements to put the pulverized feed into the packaging bag.

[0003] Although the existing fish feed sub-packaging devices can achieve the aforementioned quantitative sub-packaging function, there is a problem that it is inconvenient to adjust the required quantitative weight. Existing sub-packaging equipment usually uses an adjustment block that can move horizontally to adjust the volume of the sub-packaging bin, so as to achieve the setting change of sub-packaging feeds of different weights. There are two situations when adjusting the bin of this type of sub-packaging equipment. One is to adjust the weight after filling the sub-packaging bin with feed. In this case, the movement of the adjustment block will squeeze the feed inside the sub-packaging bin, resulting in feed powdering. And because the feed in the bin is squeezed to determine the weight, and the adjustment block does not move during the normal feeding process of the equipment, this causes the particles inside the sub-packaging bin during actual use not to have the aforementioned squeezing process. That is to say, the density of the granular feed inside the sub-packaging bin during actual use is different from that inside the bin in the adjusted state, resulting in a certain error in the final sub-packaging result. The second situation is to move the adjustment block to change its volume when the sub-packaging bin is in an empty state, then fill the feed and then discharge and weigh the feed filled inside. This method can avoid the aforementioned problems, but because it is impossible to pre-fill the corresponding weight of materials in the sub-packaging bin during the adjustment process, multiple adjustments are required to obtain the corresponding adjustment result.

[0004] In addition, existing equipment mostly uses a form of horizontally reciprocating pushing of fish feed during feeding. The feed is pushed into the sub-packaging bin through the large-arc swinging movement trajectory of the push plates on both sides. This form easily causes the feed to be powdered due to the extrusion of the feed at the lower edge position where the push plate contacts the feed during the pushing process. Summary of the Invention

[0058] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0059] Please refer to Figures 1 - 4 , the present application provides the following technical solutions:

[0060] A fish feed sub-packaging device, including a feeding part 1, a pushing part 2, and a metering part 3 arranged in sequence from top to bottom. Among them, a main feeding port 11 is provided on the feeding part 1 for receiving materials supplied by external equipment. This device is set according to different site environments and different granulation equipment, as long as it meets the requirement that the granular materials prepared by the granulation equipment can be transported to the main feeding port 11. The main feeding port 11 shown in the attached drawings of this scheme is a rectangular opening, and corresponding modifications can be made according to the actual situation. For example, a top cover can be added at the main feeding port 11, and a circular material port is opened on the top cover for connecting with the external feeding pipe and so on. Other connection methods can also be adopted, and the specific connection form with the external feeding pipeline can adopt the existing technology. This content is not the key point of this scheme and will not be elaborated here.

[0061] The pushing part 2 is arranged below the feeding part 1. The pushing part 2 includes a push plate 21 that can reciprocate horizontally. The push plate 21 is driven by a push plate driving mechanism 22 to make reciprocating movements. In each reciprocating movement cycle, one material pushing is completed. The metering part 3 is arranged below the pushing part 2. The metering part 3 includes a plurality of metering grooves 31 arranged in parallel. The metering grooves 31 are arranged in a linear array, and the distribution direction of the metering grooves 31 is perpendicular to the pushing direction of the push plate 21. The length of the push plate 21 needs to meet the requirement that it can span all the metering grooves 31. A sub-packaging feeding port 311 is opened at the top of each metering groove 31, and a sub-packaging discharging port 312 is opened at the lower part; the push plate 21 pushes the materials into the sub-packaging feeding port 311 through horizontal movement, and the sub-packaging discharging port 312 also serves as the discharging port for the sub-packaged and metered materials. Other material conveying mechanisms can be arranged outside the sub-packaging discharging port 312, or directly connected to a packing mechanism to fill the materials into the packaging bags. The metering adjustment of this scheme adopts the structural form of arranging an adjustment block 32 in the metering groove 31. The adjustment block 32 of this scheme moves in the vertical direction, and the volume of the metering groove 31 is changed through vertical movement.

[0062] In this scheme, only one material pushing is completed in one reciprocating movement of the push plate 21, that is, when the push plate 21 advances, it contacts the materials and levels the materials in the metering groove 31. When the push plate 21 returns to its original position, it no longer contacts the materials, thereby reducing the situation where the materials are crushed due to the movement of the push plate 21. And the application scheme of this application adopts an adjustment block 32 that moves in the vertical direction. When there is a situation where the materials in the metering groove 31 are too much and need to be discharged, the adjustment block 32 performs a rising action, and the materials are directly ejected from the metering groove 31, and then can be pushed away by the push plate 21, and there will be no problem that the materials are squeezed due to the movement of the adjustment block 32.

[0063] Based on the above embodiments, since the push plate 21 of this solution completes one push of the material every reciprocating motion; it is necessary to process the excess material. Therefore, this sub-packaging device is also provided with a reflux part 4. The reflux part 4 is an air conveyor mechanism, which can convey the excess feed after being pushed by the push plate 21 back to the feeding part 1 through air flow. Since the fish feed pellets are relatively light in weight, an air conveyor mechanism can be used to convey the material with air flow as the power. The excess material after being pushed by the push plate 21 is sent back to the feeding part 1 through the reflux part 4, and then feeding can be carried out again.

[0064] Based on the above embodiments, refer to Figure 4 , the feeding part 1 includes a first feeding hopper 12 located at the upper part and a second feeding hopper 13 located at the lower part. The first feeding hopper 12 is a fixed hopper, fixedly connected to the external support structure. The main feeding port 11 is opened on the first feeding hopper 12. A first discharge port is provided at the lower part of the first feeding hopper 12. In order to avoid the scattering of materials during the pushing process and protect the materials, the pushing part 2 of this solution is provided with a casing, and a number of observation windows are opened on the casing. The first feeding hopper 12 is fixed on the upper part of the casing, and the main feeding port 11 extends above the casing. The second feeding hopper 13 is arranged below the first feeding hopper 12, and the first discharge port of the first feeding hopper 12 extends into the second feeding hopper 13; a main discharge port 14 is provided at the lower part of the second feeding hopper 13; the second feeding hopper 13 is rotatably connected to the external support structure, and the axis direction of the rotation of the second feeding hopper 13 is perpendicular to the movement direction of the push plate 21.

[0065] Adopting the structural form in which the second feeding hopper 13 can swing, as Figure 4 and Figure 8 shown, the upper part of the second feeding hopper 13 is in the shape of a flared inclined structure. The lower part of the second feeding hopper 13 extends to the movement path of the push plate 21.

[0066] When the push plate 21 performs a pushing action, the upper part of the push plate 21 collides with the second feeding hopper 13, which can cause the second feeding hopper 13 to swing. On the one hand, it can ensure that the materials discharged from the second feeding hopper 13 are all in the pushing direction of the push plate 21, rather than falling in its reset direction. On the other hand, the collision causes the second feeding hopper 13 to vibrate, and at the same time, the swing of the second feeding hopper 13 collides with the first feeding hopper 12, avoiding the blockage of the discharge ports at the lower ends of the two feeding hoppers by granular materials.

[0067] Based on the above embodiments, refer to Figures 5 - 7, the main body of the metering part 3 is the metering table 33. The tabletop of the metering table 33 is a flat surface and is set in a horizontal state. The metering groove 31 is a lower groove opened on the metering table 33; the lower edge of the push plate 21 is attached to the upper surface of the metering table 33. An outlet chute 34 is fixedly arranged on one side of the metering table 33. Each metering groove 31 corresponds to a dedicated chute of the outlet chute 34 for connection with the subsequent filling equipment corresponding to the packaging bags. The dispensing outlet 312 is opened on the side wall of the metering groove 31, that is, on a vertical side wall of the metering groove 31. The whole outlet chute 34 is arranged in an inclined shape, and the high-level end of the outlet chute 34 is located outside the dispensing outlet 312. An outlet door 35 is arranged outside each dispensing outlet 312. The outlet door 35 can close the dispensing outlet 312. The outlet door 35 is linked with the door driving mechanism 36, and the door driving mechanism 36 can drive the outlet door 35 to close or open. The outlet door 35 can be a sliding door or a rotating door, etc. In this solution, the structure form of a rotating door is adopted. As Figure 6 shown, the upper ends of all the outlet doors 35 are fixedly connected to a rotating rod. The door driving mechanism 36 includes a cylinder and a short connecting rod rotatably connected to the movable end of the cylinder. One end of the short connecting rod is fixedly connected to the rotating rod, and the other end is rotatably connected to the movable end of the cylinder. The other end of the cylinder is rotatably connected to the external support structure. Through this structure, when the cylinder extends, the short connecting rod can drive the rotating rod to rotate, so that all the outlet doors 35 rotate and open. The specific opening method of the outlet door 35 can also adopt other existing technologies, which can be selected by technicians themselves and will not be elaborated here.

[0068] On the basis of the above implementation scheme, the shape of the adjusting block 32 corresponds to that of the metering groove 31. The outer side surface of the adjusting block 32 is attached to the groove wall of the metering groove 31; the upper surface of the adjusting block 32 is an inclined surface, and its low-level end faces the dispensing outlet 312.

[0069] This solution provides a specific implementation form. The metering groove 31 is a rectangular body groove hole, and the adjusting block 32 is a right trapezoidal block. Two parallel surfaces of the adjusting block 32 are respectively attached to two side walls of the metering groove 31, and one of the parallel surfaces is attached to the side wall where the dispensing outlet 312 is located. The adjusting block 32 is linked with the adjusting driving mechanism 37, and the adjusting driving mechanism 37 can drive the adjusting block 32 to rise or fall in the metering groove 31.

[0070] Because this solution adopts the structure of the adjusting block 32 rising and falling in the metering groove 31, the discharge of materials cannot be like the existing technology solution with an opening at the lower part of the metering groove 31. In order to facilitate the self-sliding of the materials, this solution adopts the structure form that the upper side surface of the adjusting block 32 is an inclined surface. As Figure 7When the material is inside the quantitative tank 31 and the discharge door 35 is closed, the material will not slide out. When the discharge door 35 is opened, the material naturally slides out along the inclined surface of the adjustment block 32 and then falls into the discharge chute 34 to complete the discharge.

[0071] The adjustment drive mechanism 37 can also be implemented in a variety of forms, as long as the adjustment block 32 can perform lifting motion. This solution adopts a motion scheme of a servo motor combined with a bevel gear combination and a screw. The output of the servo motor is phase-changed by the bevel gear combination, and the bevel gear combination can also be used as a reduction gear combination if necessary. Then the output of the bevel gear combination is transmitted to the screw, and the lifting motion of the adjustment block 32 is controlled by the threaded connection between the screw and the adjustment block 32.

[0072] Based on the above implementation scheme, see Figure 7 The adjusting block 32 includes a lower block 321 and an upper block 322, wherein the lower block 321 is linked with the adjusting driving mechanism 37, that is, it is threadedly connected with the aforementioned screw rod. The upper block 322 is arranged on the upper part of the lower block 321, and the upper side surface of the upper block 322 is the aforementioned inclined surface, and a pressure sensor is arranged between the upper block 322 and the lower block 321. In order to balance the deadweight of the upper block 322, a guide rod and a spring combination can be arranged between the upper block 322 and the lower block 321, and the deadweight of the upper block 322 is balanced by the elastic force of the spring. Combined with the zeroing of the pressure sensor, the weight of the material in the quantitative tank 31 is measured by the upper block 322, and after feedback is made, the position of the adjusting block 32 is changed accordingly in combination with the servo motor, so that the volume of the quantitative tank 31 can be more easily regulated in this way.

[0073] Based on the above implementation scheme, see Figure 8 The push plate 21 includes two parts, the lower part is an inclined plate body, and the upper part is a vertical plate body. The upper plate body and the lower plate body are integrally formed. The direction of movement of the push plate 21 when performing the pushing action during the reciprocating motion is the front side, and the direction of movement when performing the reset motion is the rear side. The lower edge of the inclined plate body of the push plate 21 is set toward the front, and the upper edge is set toward the rear; when the push plate 21 is located at the initial position of the pushing action, its lower edge is close to the side wall position of the quantitative groove 31 where the sub-packaging feed port 311 is opened, and the upper edge is away from the quantitative groove 31; the push plate 21 is linked with the push plate driving mechanism 22. The push plate driving mechanism 22 uses a cylinder as a power source, and a connecting rod connected to the cylinder is set on one side of the push plate 21, and guide rods are located on both sides of the connecting rod. The guide rods are slidably connected to the housing of the aforementioned pushing part 2. Therefore, the cylinder can be used to make the push plate 21 move smoothly.

[0074] The push plate 21 of this structural scheme can reduce the collision between the plate body and the material as much as possible, and reduce the possibility of the fish feed being powdered due to the movement of the push plate 21.

[0075] On the basis of the above embodiments, a connecting rod 23 is provided between the pushing plate 21 and the second feed hopper 13, and both ends of the connecting rod 23 are rotatably connected to the pushing plate 21 and the second feed hopper 13 respectively.

[0076] The connecting rod 23 adopts a telescopic rod structure. When the pushing plate 21 resets, it can actively pull the second feed hopper 13 towards it. On the contrary, when the pushing plate 21 performs a pushing action, it will push the second feed hopper 13 towards the other side.

[0077] The purpose of this solution is that since the adjusting block 32 adopts an inclined upper surface structure, that is to say, when the pushing plate 21 resets, it can pull the second feed hopper 13 towards the lower horizontal end of the adjusting block 32, making it easier to evenly fill the quantitative tank 31. As the pushing plate 21 moves, the second feed hopper 13 swings, which is equivalent to performing a material spreading action from one end to the other end of the quantitative tank 31 to ensure that the materials on the quantitative tank 31 are better spread.

[0078] On the basis of the above embodiments, referring to Figure 5 and Figure 8 , the quantitative part 3 further includes a surplus material discharge groove 38. The surplus material discharge groove 38 is a through groove opened on the quantitative table 33. The surplus material discharge groove 38 is a long strip groove and is located on one side of all the quantitative grooves 31.

[0079] Since the pushing plate 21 does not contact the materials during the reset action, it is necessary to consider dealing with the surplus materials generated during the feeding process of the quantitative tank 31. By setting the surplus material discharge groove 38, the surplus materials can be pushed out of the quantitative table 33 by the pushing plate 21. Combining with the collecting hopper 41 arranged under the surplus material discharge groove 38 and the return pipe group arranged between the collecting hopper 41 and the first feed hopper 12, the return transportation of the surplus materials is realized.

[0080] On the basis of the above embodiments, referring to Figure 8 and Figure 9 , a baffle 211 is also fixedly connected to the lower edge of the pushing plate 21. There is a spacing between the lower edge of the pushing plate 21 and the baffle 211, and the position of the spacing satisfies that the quantitative tank 31 can be exposed. When the pushing plate 21 is in the initial position, the baffle 211 can cover the surplus material discharge groove 38. A through groove through which the baffle 211 can pass is provided on the machine shell corresponding to the baffle 211.

[0081] Since the return part 4 connected to the surplus material discharge groove 38 has the function of negative pressure drainage, it is necessary to consider its influence on the pushing part 2. By setting the baffle 211 structure, when no pushing is carried out, the baffle 211 covers the surplus material discharge groove 38 to make it closed. As the pushing plate 21 moves, the baffle 211 slides synchronously and the surplus material discharge groove 38 is exposed.

[0082] On the basis of the above embodiments, a "Y"-shaped pipeline interface part is provided on the return pipe group of the return part 4. Through this interface part, the materials drawn by the return pipeline are divided into two groups. Taking Figure 8 the direction as an example, the right branch is the main conveying direction and the left branch is the secondary conveying direction. A filter screen is arranged between the two branches. Considering that there may still be a small amount of powdered materials, through this structure, the large-particle materials are blocked at the branch port position of the left pipeline by means of the filter screen, so that they enter the feeding part 1. The powdered materials pass through the filter screen and enter the left branch. After collection, they are granulated again. For the complex pressure drainage feeding system formed by means of air flow, it can be realized by selecting the existing technology and will not be elaborated here.

[0083] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
