The existing fully automatic grafting machines using the pasting method have problems with alignment accuracy, and compared with other working parts of the fully automatic grafting machine such as transplanting and seedling cutting, the rate of supplying grafting clips is low, which greatly reduces the work efficiency of the grafting machine.

DETAILED DESCRIPTION

[0048] In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and easy to understand, the specific implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The technical features in each embodiment of the present invention can be combined accordingly without conflicting with each other.

[0049] In the description of the present invention, it is to be understood that when an element is considered to be "connected" to another element, it may be directly connected to the other element or indirectly connected, that is, there are intermediate elements. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0050] In the description of the present invention, it should be understood that the terms "first", "second", and "third" are only used for distinguishing description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features.

[0051] like Figures 1 to 5 As shown, a cutting, clamping and sorting device for parallel grafting of multiple Solanaceae vegetables provided by the present invention mainly comprises a feeding unit, a positioning and clamping unit, a cutting unit and a clipping unit installed on a frame. Each unit cooperates with each other to realize the automatic cutting, clamping and sorting function of the device of the present invention. The cooperation process of each unit is described below.

[0052] The above-mentioned feeding unit of the present invention is used to store the material clips in the form of long wires in a spiral winding manner and convey them downstream.

[0053] The positioning and clamping unit of the present invention is installed downstream of the feeding unit, and is used to unwind the material clip of fixed length from the feeding unit and feed it into the cutting unit, while positioning the material clip located downstream of the cutting port.

[0054] The cutting unit of the present invention is used to cut the material clamp in a positioned state at the cutting opening to form a material clamp monomer for clamping the grafting object.

[0055] The clamping unit of the present invention is installed downstream of the cutting unit and has a plurality of clamping points for storing the cut material clamp monomers. When the cutting unit completes a cut, the cut material clamp monomer falls into a clamping point, and the clamping unit then switches the next clamping point to the bottom of the cutting port, and repeats the action until all clamping points store material clamp monomers.

[0056] As a preferred embodiment of the present invention, the clamping unit is used to store multiple cut material clamp monomers. When the above three units (i.e., the feeding unit, the positioning and clamping unit, and the cutting unit) cooperate to complete a cutting, the material clamp monomer enters the clamping point through the second clamping feeding channel 8, and the ejector pin 23 stably positions the material clamp ring 6-1 part, which is a cutting and clamping sorting. Then, the first connecting plate 20 is driven by the ball screw module 19 to move to the next clamping point, waiting for the next cutting, clamping and clamping sorting.

[0057] In actual use, the clamping unit can be provided with clamping points as needed. For example, the clamping unit of this embodiment is provided with five clamping points, that is, a maximum of five material clamping units can be stored at the same time.

[0058] It should be noted that the clipping in the present invention refers to fixing the cut clip monomer to the position to be clipped (i.e., the clipping point) in the device of the present invention. The original clip is a thin and long wire, generally made of bendable flexible plastic material, and the wire is cut along the cross section to form a single clip monomer.

[0059] As a preferred embodiment of the present invention, Figure 8 As shown, each material clamp monomer includes a material clamp collar 6-1 and material clamp wings 6-2 located on both sides of the material clamp collar. The material clamp collar 6-1 has a linear opening, and the opening is closed in the initial state. In the coordinated operation of various parts of the fully automatic grafting machine, the efficiency of other working parts is very high. In order to avoid affecting the overall work efficiency of the fully automatic grafting machine due to low efficiency of cutting and sorting, the present invention provides a multi-plant parallel grafting cutting and sorting device, which can store multiple (for example, five) material clamp monomers, greatly improves the efficiency of taking clips, and thus improves the overall work efficiency of the fully automatic grafting machine. At the same time, the present invention is also to realize the automation of cutting and sorting of clips for multiple parallel grafting.

[0060] Theoretically, the structural form of the feeding unit, positioning and clamping unit, cutting unit and clamping unit is not limited, as long as the functions described above can be achieved. Figures 1 to 9 , the preferred implementation form of each unit is described in detail through embodiments.

[0061] The specific form of the frame of the present invention can be adjusted according to actual needs, and its main function is to provide installation positions for each functional unit. In an embodiment of the present invention, the frame mainly includes a turntable bracket 7, a first fixing plate 16, a second fixing plate 17, a base fixing plate 30 and a support bottom plate 18, the turntable bracket 7 is installed above the first fixing plate 16 by bolts, the first fixing plate 16 is connected to the second fixing plate 17 by bolts, the second fixing plate 17 is bolted to the L-shaped base fixing plate 30, the base fixing plate 30 is connected to the support bottom plate 18 by bolts, and the turntable bracket 7 is used to install the storage bin 5.

[0062] Therefore, based on the above form, the installation positions of the above-mentioned feeding unit, positioning and clamping unit, cutting unit and clamping unit are as follows: the storage bin 5 is installed on the turntable bracket 7, the feeding unit is installed on the upper half of the first fixed plate 16, the cutting unit is installed on the support base 18 through the L-shaped second fixed plate 17 through the base fixed plate 30, and the clamping unit is installed on the ball screw module 19 through three connecting plates (namely the first connecting plate 20, the second connecting plate 21 and the third connecting plate 22), and the clamping point position determined by the ejector positioning plate 13 and the first connecting plate 20 corresponds to the position of the second clamping channel 8 of the feeding unit.

[0063] As a preferred embodiment of the present invention, Figures 1 to 5 As shown, the feeding unit mainly includes a material storage bin 5 installed on the frame, a roller group 1, a first clamp feeding channel 3, a clamp positioning plate 4 and a second clamp feeding channel 8. The material storage bin 5 is used to store the clamps required for grafting in a spiral winding form. The roller group 1 includes two rollers that are axially parallel and can roll along their respective central axes. There is a certain interval between the outer circumferences of the two rollers, and the interval serves as a clamp feeding gap for the clamps to pass through. The structure of the clamp positioning plate 4 is shown in FIG. Figure 6 As shown, it is an L-shaped whole, including a vertical plate and a horizontal bottom plate, and a clamp feeding opening for the material clip to pass through is opened on the horizontal bottom plate. After the material clip is unwound from the material storage bin 5, it passes through the clamp feeding gap, the first clamp feeding channel 3, the clamp feeding opening and the second clamp feeding channel 8 in sequence. There is a spacing interval between the outlet of the first clamp feeding channel 3 and the inlet of the clamp feeding opening, and the installation height of the active end of the positioning clamping unit on the frame is within the height range of the spacing interval.

[0064] In actual use, the storage bin 5 is fixed to the frame through the turntable bracket 7, and a first fixing plate 16 is provided below the turntable bracket 7. The bottom of the first fixing plate 16 is fixedly connected to the frame through the second fixing plate 17, the base fixing plate 30 and the supporting bottom plate 18 in sequence.

[0065] Specifically, the roller group 1, the first clamp feeding channel 3, and the material clamp positioning plate 4 are sequentially mounted on the first fixed plate 16, the second clamp feeding channel 8 is mounted on the third fixed plate 31 by bolts, the third fixed plate 31 is connected to the second fixed plate 17 by bolts, and the material clamp passes through the clamp feeding gap of the roller group 1, the first clamp feeding channel 3, the clamp feeding opening of the material clamp positioning plate 4, and the second clamp feeding channel 8 in sequence after being unwound from the material storage bin 5. The clamp feeding gap, the first clamp feeding channel 3, the clamp feeding opening, and the second clamp feeding channel 8 are all located on a straight line where the material clamp is located after being unwound from the material storage bin 5. The roller group 1 is fixed to the first fixed plate 16 by the roller connecting block 2, the first clamp feeding channel 3 and the material clamp positioning plate 4 are fixed to the first fixed plate 16, and the second clamp feeding channel 8 is fixed to the second fixed plate 17 by the third fixed plate 31. The first clamp feeding channel 3 is installed at the uppermost part of the first fixed plate 16, and the material clamp positioning plate 4 is installed at the middle part of the first fixed plate 16. The second clamp feeding channel 8 is installed on the third fixed plate 31, and its position is below the material clamp positioning plate 4. The structure of the third fixed plate 31 is as follows: Figure 7 The third fixing plate 31 is installed at the lower part of the second fixing plate 17, and the second fixing plate 17 and the L-shaped base fixing plate 30 are fixed to the supporting bottom plate 18 at the bottom of the entire mechanism by bolts. After the material clip is unwound from the material storage bin 5, it can smoothly enter the first clip feeding channel 3, the material clip positioning plate 4 and the second clip feeding channel 8 in a straight line.

[0066] The specific form of the present invention is not limited, and in the embodiment of the present invention, it is preferably implemented in the form of a rotating disk. Fig. 9 As shown, the material storage bin 5 mainly includes a material clamp rotating shaft 5-1, a material clamp rotating sleeve 5-2, a deep groove ball bearing 5-3 and a turntable 5-4. The material clamp rotating shaft 5-1 is installed in the material clamp rotating sleeve 5-2, the deep groove ball bearings 5-3 are installed on both sides of the material clamp rotating sleeve 5-2, and two turntables 5-4 are installed on the deep groove ball bearings 5-3 on both sides of the material clamp rotating sleeve 5-2 in parallel and at intervals. The space between the two turntables 5-4 is used as a space for spirally winding and storing the material clamp. The entire material storage bin 5 is rotatably mounted on the turntable bracket 1 through the material clamp rotating shaft 5-1. When the free end of the material clamp 6 is pulled, it will drive the entire turntable 5-4 to rotate around the material clamp rotating shaft 5-1, thereby realizing the passive unwinding of the material clamp 6.

[0067] As a preferred embodiment of the present invention, the positioning and clamping unit of the present invention mainly includes a feeding clamp cylinder 9, a feeding clamp clamping cylinder 11, a cylinder connecting block 10, a cylinder mounting plate 29, a material clamp clamping block 12 and a feeding clamp limit block 28. Among them, the feeding clamp cylinder 9 is installed on the first fixed plate 16 through the cylinder mounting plate 29, and its driving direction is parallel to the extension direction of the material clamp in the interval. The feeding clamp clamping cylinder 11 is connected to the cylinder connecting block 10 by bolts, and the cylinder connecting block 10 is bolted to the driving end of the feeding clamp cylinder 9 to achieve synchronous extension and retraction of the feeding clamp clamping cylinder 11 and the feeding clamp cylinder 9, that is, the feeding clamp cylinder 9 drives the feeding clamp clamping cylinder 11 to extend and retract synchronously by quantitatively extending the driving end. In order to achieve quantitative extension of the feeding clamp cylinder 9, the feeding clamp limit block 28 can be installed on the first fixed plate 16 to limit the maximum stroke of the feeding clamp cylinder 9, so that each clamping stroke of the material clamping block 12 for clamping the material is consistent.

[0068] It should be noted that the driving end of the clamp feeding cylinder 9 in the present invention refers to the displacement output end of the cylinder, and the same is true for other cylinders. In specific implementation, for ease of installation, the clamp feeding cylinder 9 is installed on the right side of the first fixed plate 16, and the output end of the clamp feeding cylinder 9 is indirectly connected to the clamp feeding clamping cylinder 11 through the cylinder connecting block 10.

[0069] In addition, a material clamping block 12 is installed at the driving end of the clamp feeding and clamping cylinder 11 and serves as the working end of the positioning and clamping unit. The material clamping block 12 is a set of controllable clamping mechanisms that can clamp and release the material clamp in the interval under the control of the clamp feeding and clamping cylinder 11. One implementation of the material clamping block 12 is two sliders that can be driven by the clamp feeding and clamping cylinder 11 to adjust the spacing. When the clamp feeding and clamping cylinder 11 is started, the two sliders are close to each other to clamp the material clamp, and when the clamp feeding and clamping cylinder 11 stops working, the two sliders release the material clamp.

[0070] In order to ensure that the overall pull-down function can be realized, the above-mentioned clamp feeding cylinder 9 and the clamp feeding clamping cylinder 11 need to be linked and controlled. The specific linkage control process is: after the material clamp is extended into the specified position of the second clamp feeding channel 8, the clamp feeding clamping cylinder 11 is in the initial clamping state, and the clamp feeding cylinder 9 drives the clamp feeding clamping cylinder 11 and the material clamp clamped by the material clamp clamping block 12 to move downstream through the quantitative extension driving end. After moving the specified length, the clamp feeding clamping cylinder 11 is controlled to release the material clamp clamping block 12, and the clamp feeding cylinder 9 drives the clamp feeding clamping cylinder 11 to return to its original position. After returning to the initial position, the clamp feeding clamping cylinder 11 controls the material clamp clamping block 12 to clamp the material clamp and return to the initial state, and the clamp feeding cylinder 9 also returns to its initial position.

[0071] It should be noted that the clamp feeding cylinder 11 is not fixed on the first fixed plate 16, but is fixed on the driving end of the clamp feeding cylinder 9 through the cylinder connecting block 10, so as to drive the clamp feeding block 12 to pull down the clamp when the clamp feeding block 12 is clamping the clamp, thereby realizing the passive unwinding of the clamp. The clamp feeding limit block 28 is installed at a specified position in the lower half of the first fixed plate 16. When the clamp feeding cylinder 9 reaches the specified stroke, the clamp feeding limit block 28 will limit the continued pushing of the clamp feeding cylinder 9 to ensure that the clamp feeding stroke is consistent each time.

[0072] As a preferred embodiment of the present invention, Figure 5 As shown, the cutting unit mainly includes a cutting cylinder 24, a blade holder 25 and a cutting blade 26. Among them, a certain gap is maintained between the outlet end face of the clamp feeding opening of the material clamp positioning plate 4 and the inlet end face of the second clamp feeding channel 8, and the gap serves as a cutting opening for cutting the material clamp. The cutting cylinder 24 is installed on the second fixed plate 17, and the cutting blade 26 is installed on the driving end of the cutting cylinder 24 through the blade holder 25. The cutting blade 26 has a blade facing the material clamp in the cutting opening, and can enter the cutting opening under the drive of the cutting cylinder 24 to cut the material clamp to form a material clamp monomer and then return to the initial position.

[0073] In addition, in order to avoid interference between the blade and the ejector pin 23 during the cutting process, the top height of the ejector pin 23 should be slightly lower than the subsequent cutting opening position.

[0074] The form of the blade holder 25 is not limited, as long as it can be installed with the cutting blade 26. However, since the cutting blade 26 needs to be replaced regularly, in the embodiment of the present invention, Figure 5 As shown, the cutting blade 26 is pressed and installed on the blade seat 25 by a detachable blade pressing plate 27, one end of the cutting blade 26 is fixedly connected to the blade seat 25, and the blade pressing plate 27 presses the other end of the cutting blade 26. The cutting blade 26 is installed obliquely so that its blade cuts the material clamp 6 at the cutting opening in an oblique manner.

[0075] In actual use, the cutting cylinder 24 is directly installed on the second fixed plate 17, and the cutting blade 26 is installed on the driving end of the cutting cylinder 24 through the blade seat 25; the cutting edge side of the cutting blade 26 faces the material clamp in the cutting opening, and can enter the cutting opening under the drive of the cutting cylinder 24, and then cut the material clamp to form a material clamp monomer and then return to the initial position.

[0076] As a preferred embodiment of the present invention, the clipping unit mainly includes a first connecting plate 20, a second connecting plate 21, a third connecting plate 22, an ejector pin 23, a ball screw module 19, an ejector pin positioning plate 13, a fourth connecting plate 14 and a guide rail 15. In order to meet the configuration requirements of the space, the first connecting plate in this unit is mounted on the second connecting plate by bolts, and the second connecting plate is mounted on the third connecting plate by bolts, that is, the first connecting plate 20, the second connecting plate 21 and the third connecting plate 22 are directly connected by bolts to form a whole, and the third connecting plate 22 is mounted on the ball screw module 19, which drives each connecting plate to move parallel along the guide rail 15.

[0077] The fourth connecting plate 14 is fixedly connected to the ejector positioning plate 13 and the first connecting plate 20 by bolts, and a plurality of ejectors 23 are vertically installed on the ejector positioning plate 13 by bolts along the length direction of the guide rail 15. The ejector 23, as a clamping point, can just be inserted into the material clamp collar 6-1 of the material clamp output from the outlet of the second clamp feeding channel 8, and the top height of the ejector 23 is lower than the cutting opening. In actual use, the second clamp feeding channel 8 has a channel for the material clamp to pass through, and its length matches the length of a single cutting of the material clamp. After each cutting unit completes a cutting action, the material clamp passes through the second clamp feeding channel 8 to reach the clamping point of the ejector positioning plate 13, and the ejector 23 can just be inserted into the material clamp collar of the material clamp output from the outlet of the second clamp feeding channel 8, that is, the cut material clamp monomer is stored in the ejector positioning plate 13, and then positioned by the ejector 23 below. After completing this action, the ball screw module 19 drives the first connecting plate 20 to move along the guide rail 15, switches to the next clamping point, and repeats the previous action until all the clamping points are arranged and clamped, so that the clamping mechanism of the grafting machine can take the clamps.

[0078] The installation positions of the above-mentioned cylinders, plates and blocks on the frame can be arranged reasonably so as not to interfere with each other. Figure 1 to Figure 5As shown, in the embodiment of the present invention, the overall layout is as follows: the feeding clamp cylinder 9 is installed on the upper right part of the first fixed plate 16 through the cylinder mounting plate 29, the feeding clamp clamping cylinder 11 is installed on the left side of the feeding clamp cylinder 9 connecting block 10 at the lower end of the feeding clamp cylinder 9, and the material clamp clamping block 12 is connected to the lower side of the feeding clamp clamping cylinder 11, and the clamping block is installed to the left, and the clamping part is in a straight line with the first feeding clamp channel 3 and the second feeding clamp channel 8. The main body of the cutting cylinder 24 is installed on the upper part of the second fixed plate 17 to avoid interference with other mechanisms. The roller group 1 is installed on the upper part of the first fixed plate 16 and in a straight line with the first feeding clamp channel 3, and the material clamp positioning plate 4 is between the first feeding clamp channel 3 and the second feeding clamp channel 8. The material clamp can vertically pass through the roller group 1, the first feeding clamp channel 3, the material clamp positioning plate 4, and the second feeding clamp channel 8 in sequence, and the cylinder connecting block 10, the feeding clamp clamping cylinder 11, and the material clamp clamping block 12 are fixed in relative positions, and the material clamp clamping block 12 can move vertically back and forth. The material clamping block 12 is driven to move vertically under the drive of the clamp feeding cylinder 9. The moving distance is consistent with the stem length that needs to be protected for the grafted seedlings, that is, the length of the material clamp protective sleeve. Generally, the single vertical moving distance can be set to 17 mm. The cutting port is located between the material clamp positioning plate 4 and the second clamp feeding channel 8. Directly below the second clamp feeding channel 8 is the ejector pin 23 installed on the ejector pin positioning plate 13. The ejector pin 23 is directly opposite to the material clamp outlet of the second clamp feeding channel 8. The second clamp feeding channel 8 is installed on the third fixed plate 31, and the third fixed plate 31 is installed on the lower part of the second fixed plate 17. The second fixed plate 17 and the L-shaped base fixing plate 30 are fixed to the support bottom plate 18 at the bottom of the entire mechanism by bolts. In order not to interfere with other parts, the ball screw module 19 is installed on the rear half of the frame of the entire mechanism. There is a guide rail 15 under the first connecting plate 20, which can reciprocate parallel to the left and right on the guide rail 15.

[0079] In another embodiment of the present invention, based on the above-mentioned multi-plant parallel grafting cutting, clamping and clipping device, a multi-plant parallel grafting cutting, clamping and clipping method is also provided, and the steps are as follows:

[0080] The first step is the feeding preparation stage: the material clamp in the form of a long wire and in a free closed state is stored in the storage bin 5 in a spiral winding manner, one end of the material clamp is vertically passed through the feeding clamp gap, the first feeding clamp channel 3, the feeding clamp mouth and the second feeding clamp channel 8 in sequence, and the feeding clamp clamping cylinder 11 is started to make the material clamp clamping block 12 clamp the material clamp.

[0081] The second step is the clamping and positioning stage: the clamp feeding cylinder 9 is started, and under the drive of the clamp feeding cylinder 9, the clamp feeding clamping cylinder 11 and the material clamp clamped by the material clamp clamping block 12 move downward synchronously by a preset fixed length, and the material clamp passes through the outlet of the clamp feeding port and enters below the cutting port.

[0082] The third step is the material cutting stage: the material cutting cylinder 24 starts, driving the cutting blade 26 on the blade seat 25 to push forward, and completes the cutting of the material clamp at the cutting opening above the second clamp feeding channel 8 (in this embodiment, the length of the material clamp monomer cut at this time is 17 mm). Then the material cutting cylinder 24 controls the cutting blade 26 to retract, and the cut material clamp monomer enters the clamping point in the ejector positioning plate 13, and the ejector 23 can just be inserted into the material clamp ring 6-1 of the material clamp output from the outlet of the second clamp feeding channel 8. After cutting, the clamp feeding clamping cylinder 11 controls the clamp clamping block 12 to release the material clamp, and the clamp feeding cylinder 9 starts to restore the clamp feeding clamping cylinder 11 together with the clamp clamping block 12 to the initial position. The clamp feeding clamping cylinder 11 starts to control the clamp clamping block 12 to clamp the material clamp again.

[0083] The fourth step is the clamp sorting stage: during the repeated second step of clamping and positioning and the third step of cutting, that is, each time the material clamp is cut by the cutting blade 26, the material clamp monomer enters the current clamping point of the ejector positioning plate 13. Then the ball screw module 19 drives the ejector positioning plate 13 to move a certain distance along the guide rail 15, aligning the next clamping point with the outlet of the second clamp feeding channel 8, so that the ejector 23 at the clamping point can just be inserted into the material clamp ring 6-1 of the material clamp output from the outlet of the second clamp feeding channel 8. Then continue to cut and sort the next material clamp monomer until each clamping point on the ejector positioning plate 13 is stored with material clamps, waiting for the grafting machine to take the clamps.

[0084] It should be noted that the above-mentioned second step clamping and positioning stage and the third step cutting stage need to be repeated continuously, so as to continuously cut the material clamp into sections of material clamp monomers, and then each material clamp monomer will be arranged to the specified position through the fourth step cutting and sorting stage in the next cycle.

[0085] The above-described embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. A person skilled in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
