Technical Field

[0001] The invention relates to the technical field of matrix filling, in particular to an automatic matrix filling device for a non-woven seedling bag. Background Art

[0002] At present, most automatic seedling matrix filling equipment is for seedling cups, because seedling cups are generally made of plastic, have a relatively rigid structure, and are in an open state, so they can stand upright to complete the transportation and filling of seedling matrix.

DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figure 1 As shown, the present embodiment provides a non-woven seedling bag matrix automatic filling device, including a matrix lifting mechanism 1, a matrix unloading mechanism 2 arranged below the discharge end of the matrix lifting mechanism 1, and a matrix bag-entering mechanism 3 arranged below the matrix unloading mechanism 2. Among them, the matrix lifting mechanism 1 is used to transport the matrix from a low place to a high place, so that the matrix can pass through the matrix unloading mechanism 2 and the matrix bag-entering mechanism 3 in sequence under the action of its own gravity to automatically complete the filling. The matrix unloading mechanism 2 is mainly used to control the unloading amount of the matrix and accurately introduce the matrix into the seedling bag. The matrix bag-entering mechanism 3 is responsible for completing the bag taking, bag opening and stretching actions of the seedling bag to ensure that the seedling bag can stably receive a set amount of matrix. The specific structure and working principle of the above three parts are respectively introduced in detail below.

[0019] like Figure 2-4As shown, the matrix lifting mechanism 1 includes a support frame 11 and a belt conveyor 12 installed on the support frame 11. The belt conveyor 12 is inclined and the conveying direction is from a low place to a high place, so as to convey the matrix to a high place. In order to facilitate the feeding of the matrix to the belt conveyor 12, a matrix feeding box 13 is arranged above the lower part of the belt conveyor 12, so that more matrix can be fed into the matrix feeding box 13 and gradually and orderly conveyed to a high place through the belt conveyor 12. Specifically, a material box limiting frame 14 is installed on the belt conveyor 12 at the upstream and downstream ends of the matrix feeding box 13, which is used to install and fix the matrix feeding box 13 to prevent the matrix feeding box from pressing on the belt 121 of the belt conveyor 12 and affecting its normal conveying. Therefore, there is a certain gap between the bottom surface of the matrix feeding box 13 and the belt 121. However, in order to prevent the matrix from falling downstream from the gap, an elastic baffle 131 is provided at the downstream end of the matrix feed box 13. The elastic baffle 131 can be made of plastic or rubber materials, so as to prevent the matrix from falling without affecting the normal conveying of the belt. In order to ensure the efficiency and stability of the belt conveying matrix, a plurality of matrix push plates 122 are evenly distributed along the length direction of the belt 121 to ensure the matrix carrying capacity on the belt. At the same time, the elastic baffle 131 will not affect the normal passage of the matrix push plate 122. Finally, in order to make the matrix output from the higher position of the belt conveyor more concentrated so that the matrix unloading mechanism 2 below can receive it, a matrix discharge hopper 15 is installed below the higher position of the belt conveyor 12. Thus, only a sufficient amount of matrix needs to be fed into the matrix feed box by manual or other conveying equipment, and the matrix lifting mechanism can automatically and orderly transport the matrix stably from the lower position to the higher position, and feed it into the matrix unloading mechanism 2 below from the higher position.

[0020] like Figure 5 and 6As shown, the matrix feeding mechanism 2 includes a feeding frame 21, a receiving hopper 22 disposed on the upper part of the feeding frame 21, a quantitative pushing assembly disposed below the receiving hopper 22, a second material blocking plate 23 disposed below the quantitative pushing assembly, and a feeding barrel 24 disposed below the second material blocking plate 23. Among them, a second feeding hole 231 is disposed on the second material blocking plate 23 at the connection to the feeding barrel 24, and the second feeding hole 231 and the discharge end of the receiving hopper 22 are staggered with each other. The quantitative pushing assembly includes a pushing cylinder 251, a first material baffle plate 252 arranged at the output end of the pushing cylinder 151, and a quantitative material barrel 253 arranged below the first material baffle plate 252. The first material baffle plate 252 is provided with a first discharge hole 2521 at the connection with the quantitative material barrel 253. The first material baffle plate 252 is slidably matched with the lower end of the receiving hopper 22, and the lower end of the quantitative material barrel 253 is slidably matched with the second material baffle plate 23. The upper and lower ends of the quantitative material barrel 253 are both open. In this way, since the second discharge hole 231 and the discharge end of the receiving hopper 22 are staggered, when the upper end of the quantitative barrel 253, that is, the first discharge hole 2521, is aligned with the discharge end of the receiving hopper 22, the lower end of the quantitative barrel 253 abuts against the second material baffle plate 23. When the quantitative barrel 253 is filled with the matrix, it moves toward the second discharge hole 231 driven by the pushing cylinder 251. During this process, the upper end of the quantitative barrel 253 and the discharge end of the receiving hopper 22 are gradually misaligned, that is, the discharge end of the receiving hopper 22 will gradually abut against the first material baffle plate 252, blocking the discharge of the matrix; at the same time, the lower end of the quantitative barrel 253 is gradually aligned with the second discharge hole 231, that is, the matrix in the quantitative barrel 253 can be discharged downward from the second discharge hole 231 and the discharge barrel 24. Subsequently, the push cylinder 251 drives the quantitative barrel 253 to reset, the lower end of the quantitative barrel 253 is blocked by the second baffle plate 23 again, and the upper end is realigned with the discharge end of the receiving hopper 22, and the matrix in the receiving hopper 22 can automatically fall into the quantitative barrel 253, and no other switch structure is required, and the quantitative unloading action can be carried out in an orderly manner. Therefore, the volume of the quantitative barrel 253 determines the amount of matrix poured into each seedling bag, and the quantitative barrel of the required volume can be selected according to the needs. The matrix unloading mechanism effectively realizes the quantitative filling of the matrix through the design of the mechanical structure, avoiding the more complicated means such as sensor weighing in the prior art, and the overall work efficiency is higher.

[0021] In addition, in order to ensure the accuracy of the moving position of the quantitative barrel 253, thereby ensuring the efficiency of receiving and releasing the matrix, guide plates 254 are connected to the opposite sides of the first baffle plate 252, and multiple reinforcing connecting rods 255 are connected between the two guide plates 254. The second baffle plate 23 is provided with a guide groove 232 that matches the guide plate 254. The movement of the guide plate along the guide groove can effectively ensure the accuracy of the moving position of the quantitative barrel.

[0022] Since the matrix bagging mechanism 3 below the matrix unloading mechanism 2 has a structure of rotating at multiple stations, the unloading barrel 24 cannot be extended into the matrix bagging mechanism 3 all the time. If the unloading barrel 24 is always in a suspended state, the matrix cannot be accurately delivered into the seedling bag, which is bound to cause problems such as matrix splashing. Therefore, a telescopic cylinder 261 is slidably connected to the outside of the unloading barrel 24, and the telescopic cylinder 261 is driven to be telescopic by a telescopic cylinder 262. That is, when the matrix needs to be poured into the seedling bag, the telescopic cylinder 261 extends downward into the seedling bag. After the filling is completed, the telescopic cylinder 261 is reset upward to avoid affecting the station rotation switching of the matrix bagging mechanism 3. Specifically, a driving plate 263 is provided on the telescopic cylinder 261, and two telescopic guide rods 264 are provided between the driving plate 263 and the second material blocking plate 23 above it to ensure the stability of the telescopic action of the telescopic cylinder, and the telescopic cylinder 262 is arranged between the unloading frame 21 and the driving plate 263.

[0023] In order to effectively control the substrate quality in the receiving hopper 22 and avoid excessive overflow of the substrate, a rotary resistance level switch 27 is provided in the receiving hopper 22, and the signal output end of the rotary resistance level switch 27 is connected to the controller of the belt conveyor 12. When the substrate in the receiving hopper 22 submerges the rotary resistance level switch 27, the rotary resistance level switch 27 can generate a corresponding signal, which is output to the controller of the belt conveyor 12 to control the belt conveyor to suspend feeding; when the substrate in the receiving hopper 22 is lower than the rotary resistance level switch 27, a corresponding signal is generated to make the belt conveyor feed again. In this way, the appropriate substrate quality in the receiving hopper 22 can be stably maintained, which ensures sufficient supply of the substrate and avoids excessive overflow of the substrate.

[0024] like Figure 7-10As shown, the matrix bag-feeding mechanism 3 includes a bag-feeding frame, a turntable assembly arranged on the bag-feeding frame, three groups of bag-supporting assemblies evenly distributed on the turntable assembly, and a bag-taking and opening assembly arranged oppositely below one of the groups of bag-supporting assemblies. The bag-taking and opening assembly includes a bag-opening cylinder 321 and a bag-taking cylinder 322 arranged oppositely, a needle suction cup 323 arranged at the output ends of the bag-opening cylinder 321 and the bag-taking cylinder 322, a rotating cylinder 324 whose output end is connected to the bag-taking cylinder 322, and a bag-taking and opening assembly arranged at the bag-taking cylinder 321. The bag slot 325 below the cylinder 322, wherein the bag entering frame is mainly composed of an external frame and an internal bracket, the structure is relatively conventional and is not shown in the figure, the bag opening cylinder 321 and the rotating cylinder 324 are both installed on the bag entering frame through horizontal steel pipes, and because the bag taking cylinder 322 needs to complete the action of taking bags from the outside, the bag taking cylinder 322 and the rotating cylinder 324 are located on the outside of the turntable assembly, while the bag opening cylinder 321 is located on the inside of the turntable assembly. The present matrix bag-entering mechanism realizes automatic bag taking and bag opening of the seedling bag mainly by setting a bag taking and opening component, and its working principle is as follows: first, driven by the rotating cylinder 324, the needle suction cup at the output end of the bag taking cylinder 322 faces downward, and then the bag taking cylinder 322 extends to make the needle suction cup at its output end contact the seedling bag in the bag groove 325, and absorbs a seedling bag through the needle suction cup, and then the bag taking cylinder 322 resets upward to avoid interference with the bag groove 325 during rotation; then the rotating cylinder 324 resets to make the output end of the bag taking cylinder 322 face the output end of the bag opening cylinder 321 again, and then the bag taking cylinder 322 and the bag opening cylinder 321 move toward each other successively or simultaneously, so that the needle suction cup at the output end of the bag opening cylinder 321 contacts and absorbs the other side of the seedling bag; then the bag opening cylinder 321 contracts and resets to open the seedling bag.

[0025] Since the extended length of the bag taking cylinder 322 is limited, when the seedling bag in the bag slot 325 is gradually taken away, its height will drop, so that the bag taking cylinder 322 will not be able to reach it. Therefore, a bag holding electric cylinder 326 is provided below the bag slot 325, and a bag holding plate 327 is provided at the output end of the bag holding electric cylinder 326. The bag holding plate 327 extends upward into the bag slot 325, that is, the bag holding plate 327 serves as the bottom surface of the bag slot 325. When the height of the seedling bag is reduced, the bag holding plate 327 is raised by the lifting action of the bag holding electric cylinder 326 to ensure that the topmost seedling bag is within the telescopic range of the bag taking cylinder 322. Generally, the height position of the seedling bag can be monitored by a photoelectric sensor, and the corresponding signal is fed back to the controller of the bag holding electric cylinder 326 to realize automatic control. In addition, in order to facilitate the addition of the seedling bag, one side of the bag slot 325 is open, and the corresponding bag input rack is also open at this location, so as to facilitate the addition of the seedling bag into the bag slot 325 from the side.

[0026] Three groups of bag-supporting assemblies are arranged on the turntable assembly, so that the first group of bag-supporting assemblies can be in the seedling bag receiving position 301, while the second group of bag-supporting assemblies can support the seedling bag in the empty position 302, and the third group of bag-supporting assemblies can support the seedling bag in the matrix filling position 303; then the first group of bag-supporting assemblies are transferred to the empty position 302, while the second group of bag-supporting assemblies are transferred to the matrix filling position 303, and the third group of bag-supporting assemblies are transferred to the seedling bag receiving position 301, and this cycle can realize uninterrupted matrix filling work and improve work efficiency. Among them, the unloading barrel 24 is located above the matrix filling position 303, and the bag-opening assembly is located below the seedling bag receiving position 301. Although two workstations can also realize the above functions, the angle required for the two workstations to rotate each time is large, and the efficiency will be relatively reduced.

[0027] Specifically, the turntable assembly includes an upper turntable 331, a lower turntable 332, a connecting column 333 connecting the centers of the upper and lower turntables, and a turntable motor 334 driving the connecting column 333. A material hole 3301 is provided at the corresponding position of the upper turntable 331 and the lower turntable 332. The lower side of the upper turntable 331 is used to set the bag support assembly. The material hole on the upper turntable 331 is used for the downward extension of the telescopic cylinder 261, and the material hole on the lower turntable 332 is used for the seedling bag to fall downward after filling. Specifically, in order to prevent the seedling bag from colliding with the edge of the material hole on the lower turntable 332, a seedling bag retaining ring 335 is provided at the material hole of the lower turntable 332 to guide the falling of the seedling bag. At the same time, in order to facilitate the seedling bag to be sent into the seedling bag retaining ring 335 by the bag taking cylinder 322, the seedling bag retaining ring 335 is opened on one side close to the bag taking cylinder 322. In addition, the connecting column 333 is rotatably connected to the bearing seat on the bag feeding frame by setting a central axis, and the central axis extends below the bearing seat. The turntable motor 334 is set below the bag feeding frame at the bearing seat, and the output end is connected to the central axis through a coupling. In order to reduce the weight of the equipment, the upper turntable 331 and the lower turntable 332 are both designed to be lightweight. Except for the part where the material hole and the bag support assembly are set, the area of ​​other parts is minimized as much as possible. At the same time, a number of weight reduction holes 3302 are also set to take into account both lightweight and structural strength.

[0028] The bag-supporting assembly includes a mounting plate 341, a lifting cylinder 342 and a lifting guide rod 343 connecting the mounting plate 341 and the upper turntable 331, four bag-supporting cylinders 344 arranged below the mounting plate 341, and bag-supporting rods 345 arranged vertically downward at the output ends of the bag-supporting cylinders 344, and the output ends of the four bag-supporting cylinders 344 face the middle of the mounting plate 341. The lifting cylinders 342 and the lifting guide rods 343 each have two relatively arranged ones to ensure the stability of the lifting and lowering action of the mounting plate and the components below it. The working principle of the bag support assembly is as follows: first, the four bag support cylinders 344 are all in an extended state, that is, the four bag support rods 345 are in a state of being close to each other. When the seedling bag below is opened by the bag opening cylinder 321, the lifting cylinder 342 drives the entire mounting plate 341 to move downward. At this time, the four close bag support rods 345 are inserted downward into the seedling bag. Then, the four bag support cylinders 344 contract to drive the four bag support rods 345 to disperse synchronously, thereby opening the seedling bag, and relying on the friction between the bag support rods 345 and the seedling bag, the seedling bag is stably sleeved on the four bag support rods 345. When the seedling bag is filled with the matrix, the four bag support rods 345 are pulled out upward and reset, and the seedling bag falls under the action of the gravity of the matrix. The bag support assembly uses four bag support rods 345 to realize the opening action of the seedling bag, which ensures the limit of the opening to ensure the amount of matrix received, and avoids setting too many bag support cylinders, taking into account lightweight.

[0029] Specifically, since a certain pressure is required between the bag-supporting rod 345 and the seedling bag, in order to ensure the stability of the position and movement of the bag-supporting rod 345, a connecting plate 346 is provided at the output end of the bag-supporting cylinder 344, and the bag-supporting rod 345 is vertically connected to the lower end of the connecting plate 346. A slider 347 is provided on the connecting plate 346, and a slide rail 348 is provided on the lower side of the mounting plate 341, and the slider 347 cooperates with the slide rail 348. In addition, in order to allow the four bag-supporting rods 345 to be as close as possible to facilitate smooth insertion into the seedling bag, one end of the connecting plate 346 for setting the bag-supporting rods has a chamfered structure 3461, so that the four connecting plates can be as close as possible. At the same time, an introduction slope 3451 is provided on the outer side of the lower end of the bag-supporting rod 345 to further ensure that the bag-supporting rod can be smoothly inserted into the seedling bag.

[0030] In summary, the working principle of the device is as follows: the matrix is ​​fed into the matrix feed box 13 manually or by other conveying equipment, and the belt conveyor 12 gradually conveys the matrix in the matrix feed box 13 upward, and continuously conveys the matrix to the receiving hopper 22 through the matrix discharge hopper 15. The quantitative barrel 253 below the receiving hopper 22 is first aligned with the lower end of the receiving hopper 22 to fill the matrix. When the matrix filling position 303 below the lower barrel 24 turns over an empty seedling bag that is stretched, the telescopic cylinder 261 passes through the upper turntable 331 downward and extends into the seedling bag; then the quantitative barrel 253 is pushed to the second discharge hole 231 by the push cylinder 251, and the matrix in the quantitative barrel 253 is poured into the seedling bag through the lower barrel 24 and the telescopic cylinder 261, and then the quantitative barrel 253 is reset to receive the next barrel of matrix; at the same time, the bag support rod that stretches the seedling bag is pulled out and reset upward, and the filled seedling bag falls downward and is transported away by other conveying equipment. Then the turntable rotates one station, the bag-opening assembly that has just released the seedling bag moves to the seedling bag receiving position 301, the bag-opening assembly that has just opened a seedling bag on the seedling bag receiving position 301 moves to the empty position 201, and the bag-opening assembly that has opened a seedling bag on the empty position 302 moves to the matrix filling position 303, and the above actions are repeated to efficiently complete the automatic filling of the matrix of the seedling bag. The action principle of the bag-opening assembly is as described above, which is responsible for taking the seedling bag out of the bag slot, sending it to the bottom of the bag-opening assembly at the seedling bag receiving position, and initially opening it, which will not be described in detail here.
