DETAILED DESCRIPTION

[0036] Referring to Figure 2 and Figure 6 The folding and pressing mechanism 1 has two turning blocks 11, which can synchronously rotate towards each other around the same virtual center; the virtual center is located between the two turning blocks 11; the two turning blocks 11 are symmetrically arranged on the two sides of the virtual center.

[0037] Referring to Figure 1 The folding and pressing mechanism 1 of the utility model is used for preforming the protective shell. The protective shell comprises two half shells 5 connected with each other, and each half shell 5 is provided with a pressing edge 53. One of the pressing edges 53 is provided with a buckling post 51, and the other pressing edge 53 is provided with a buckling hole 52 corresponding to the buckling post 51.

[0038] The protective shell is placed in an open and flat state, and the two half shells 5 are placed on the two turning blocks 11 respectively. When the two turning blocks 11 synchronously rotate and turn upwards, the two half shells 5 of the protective shell can be folded. Alternatively, the two turning blocks 11 simultaneously turn upwards by 90° (or slightly less than 90°), the two half shells 5 are folded, and the buckling post 51 approaches or abuts against the buckling hole 52.

[0039] The ends of the two turning blocks 11 are respectively provided with an extruding part; the extruding part can synchronously rotate with the corresponding turning block 11; after the two half shells 5 are folded, the two extruding parts simultaneously extrude the pressing edges 53 of the half shells 5 on the corresponding side, so that the buckling post 51 and the buckling hole 52 at the extruding position are pressed together; the preforming of the protective shell is realized.

[0040] In combination withFigure 2 And Figure 4 The utility model discloses a protection shell's conveying direction is benchmark, defines the end of turnover block 11. The buckling post 51 - buckle hole 52 that extruding part press fits is located the most front end of protection shell, and other groups of buckling post 51 - buckle hole 52 are buckled in proper order when subsequent through the buckling assembly 3.

[0041] The utility model discloses the synchronous rotation of extruding part of folding and pressing mechanism 1's turnover block 11. In the process that two half shells 5 are folded in two by turnover block 11, two extruding parts rotate to extruding position with turnover block 11 synchronously. When two half shells 5 are folded in two, two extruding parts extrude the pressing edge 53 of half shell 5 simultaneously, and one group of buckling post 51 and buckle hole 52 complete press fit connection. There is almost no delay between two actions. Compared with prior art, the folding and pressing action of the utility model is synchronous, greatly shortens the time of protection shell preforming, and further improves the production efficiency of protection shell buckling forming.

[0042] Referring to Figure 7 As an embodiment of the extruding part of folding and pressing mechanism 1 of the utility model, the extruding part is protrudingly arranged at the end of turnover block 11. When the turnover block 11 rotates, the extruding part rotates synchronously. When two turnover blocks 11 rotate to the position, because the extruding part is protrudingly arranged relative to the turnover block 11, the high point position of two extruding parts is closer to the center, the distance between two extruding parts is smaller, and then enough extrusion force is formed on the pressing edge 53 of half shell 5, so that one group of buckling post 51 and buckle hole 52 are press fitted, and the preforming of protection shell is completed.

[0043] The skilled person in the art can set the fixed position of the extruding part on the turnover block 11 according to the length of the protection shell and the position of the buckling post 51 and the buckle hole 52. When two turnover blocks 11 are folded, the two extruding parts extrude the buckling post 51 and the buckle hole 52 respectively, so that they are smoothly press fitted.

[0044] Optionally, the skilled person in the art can set the height of the protruding extruding part or the maximum rotation angle of two turnover blocks 11, so that when two turnover blocks 11 are folded, the two extruding parts just complete extrusion, avoiding excessive extrusion force.

[0045] Optionally, the extruding part is an extruding block 8. The cross-sectional shape is preferably a circular arc shape. The vertex position is protruding, and it is easy to extrude to the position. Preferably, the extruding block 8 of the utility model is spherical or cylindrical.

[0046] Optionally, the cross-sectional shape of the extruding block 8 can also be polygonal, trapezoidal, triangular, etc.

[0047] Further, the extruding block 8 is screwed on the turnover block 11, the height of the protruding extruding block 8 can be adjusted, so that it is matched with the extrusion degree.

[0048] Referring toFigure 6 As an embodiment of the pressing mechanism 1 of this utility model, the pressing part and the flipping block 11 are separately arranged; the pressing part is arranged adjacent to the flipping block 11 on the corresponding side;

[0049] Combination Figure 4 The extrusion section and the flipping block 11 are both connected to the same flipping drive assembly 2; the flipping drive assembly 2 is configured to drive the two extrusion sections and the two flipping blocks 11 to rotate synchronously.

[0050] Optionally, the two extrusion sections and the two flipping blocks 11 have the same maximum rotation angle. Since the half-shell 5 usually has good plasticity, and the buckle 51 protrudes relative to the pressure edge 53, when the two flipping blocks 11 and the two extrusion sections rotate synchronously to the maximum angle, the buckle 51 can be squeezed into the buckle hole 52.

[0051] Furthermore, the maximum rotation angle of the two extrusion sections is slightly greater than the maximum rotation angle of the two flipping blocks 11. After the two flipping blocks 11 fold the two half-shells 5 of the protective shell to the maximum rotation angle, the two extrusion sections continue to rotate a small angle to continue applying extrusion force to the two pressing edges 53, ensuring that the buckle 51 and the buckle hole 52 are pressed together, avoiding the situation where the pressing is not firm. In this embodiment, the extrusion section and the flipping block 11 rotate synchronously, and the extrusion section only continues to rotate at the last moment to complete the extrusion. The actions of the two are basically without delay, which significantly shortens the folding and pressing time and improves production efficiency.

[0052] See Figure 6 As an embodiment of the extrusion part of the folding and pressing mechanism 1 of this utility model, the extrusion part is an extrusion block 8; two extrusion blocks 8 and two flipping blocks 11 are respectively slidably connected to a track plate 18; the track plate 18 is provided with two first arc grooves 181 whose centers coincide with the virtual center; the two first arc grooves 181 are symmetrically arranged on both sides of the virtual center; a second arc groove 182 is concentrically arranged on one side of each of the two first arc grooves 181;

[0053] A first guide block 183 is slidably disposed in each of the two first arc grooves 181; a second guide block 184 is slidably disposed in the second arc groove 182.

[0054] The first guide block 183 and the second guide block 184 of the two track plates 18 are respectively connected to the corresponding flipping block 11 and extrusion block 8;

[0055] The rotation trajectory of the flipping block 11 and the squeezing block 8 is jointly defined by the first arc groove 181 and the second arc groove 182, which avoids the risk of self-rotation and makes its rotation trajectory stable and reliable.

[0056] See Figure 5As an embodiment of the turnover driving assembly 2, the turnover driving assembly comprises two vertically arranged lifting slide rails 17; a lifting plate base 16 is slidably connected between the two lifting slide rails 17; the lifting plate base 16 is rotationally connected with a lifting top rod 15, and the lifting top rod 15 is further transmissionally connected with a lifting motor 13;

[0057] In combination Figure 9 The turnover block 11 and the extrusion block 8 are respectively rotationally connected with a lifting connecting rod 12, and the lifting connecting rod 12 is further rotationally connected on the lifting plate base 16;

[0058] The lifting top rod 15 is reciprocally moved by the rotation driving of the lifting motor 13, so as to reciprocally move the lifting plate base 16, and the synchronous rotation of the turnover block 11 and the extrusion block 8 is completed.

[0059] As an embodiment of the turnover driving assembly, the lifting motor 13 is transmissionally connected with a reciprocating swing arm 14; the reciprocating swing arm 14 is rotationally connected with the lifting top rod 15, and the lifting top rod 15 is further rotationally connected with the lifting plate base 16;

[0060] When the reciprocating swing arm 14 is rotated to the highest point, the two turnover blocks 11 can completely fold the two half shells 5. The reciprocating swing arm 14 is continuously rotated, so as to reset the two turnover blocks 11 and the extrusion block 8.

[0061] Referring to Figure 8 As an embodiment of the turnover driving assembly, the lifting motor 13 is transmissionally connected with a driving wheel 21, and the driving wheel 21 is eccentrically connected with the lifting top rod 15.

[0062] As an embodiment, the lifting slide rail 17 is in a cylindrical shape, and the lifting plate base 16 is slidably sleeved with the lifting slide rail 17; the stress of the two is optimized, so that the lifting plate base 16 can stably slide along the lifting slide rail 17.

[0063] Optionally, the distance between the two lifting slide rails 17 can be appropriately set by those skilled in the art, so as to leave sufficient installation space for other components.

[0064] Referring to Figure 9 As an embodiment, the lifting plate base 16 is provided with a supporting shaft 22; the lifting connecting rods 12 of the extrusion blocks 8 and the turnover blocks 11 located on the same side are rotationally penetrated on the same supporting shaft 22; an adjusting nut 24 is screwed on the lifting connecting rod 12; a top spring 23 is sleeved and clamped on the adjusting nut 24 and the supporting shaft 22 on the lifting connecting rod 12;

[0065] The utility model discloses a through hole is established on the lifting connecting rod 12 and is sleeved with support shaft 22, and there is a small gap between the through hole and support shaft 22, so that the lifting connecting rod 12 can rotate smoothly. By screwing the adjusting nut 24, the top spring 23 is in the compression state. Under the action of the elastic tension of the top spring 23, the lifting connecting rod 12 has an upward movement trend relative to the support shaft 22, and then the through hole of the lifting connecting rod 12 abuts against the bottom of the support shaft 22, so that the lifting connecting rod 12 cannot descend under the action of gravity, the turnover block 11 and the extruding block 8 cannot reach the maximum stroke completely, and the effect of pressing is affected.

[0066] Meanwhile, if the thickness of the pressing edge 53 of the half shell 5 is slightly large, a counterthrust can be generated during extrusion, so that the lifting connecting rod 12 slightly moves downward, and the extrusion force is avoided from being too large.

[0067] The folding and pressing mechanism 1 of the utility model simultaneously drives the extruding part and the turnover block 11 through a set of turnover driving assembly 2, the equipment structure is simplified, and the equipment cost is reduced.

[0068] Referring to Figure 2 And Figure 3 The utility model also provides a sequential buckling device, which comprises the folding and pressing mechanism 1 and a buckling assembly 3 arranged in sequence along a conveying direction.

[0069] The buckling assembly 3 comprises at least one compression wheel set, and the compression wheel set comprises two horizontally arranged compression wheels 31.

[0070] The compression wheel 31 has a pressing part, and the pressing parts of the two compression wheels 31 form a compression space therebetween.

[0071] Further, the pressing part is a compression disc 311, and a surface contact is formed between the side surface of the compression disc 311 and the pressing edge 53 of the half shell 5, so that the pressing force can fully act on the buckling column 51 and the buckling hole 52.

[0072] The aforementioned protective shell is fed between the two compression wheels 31, and the pressing edges 53 of the two half shells 5 enter the compression space. With the forward conveying of the protective shell, the buckling columns 51 and the buckling holes 52 are sequentially buckled.

[0073] Better, the compression wheel 31 also has a guide part, and the guide parts of the two compression wheels 31 jointly clamp the body of the protective shell, so that the posture is stable, and the compression quality of the pressing part is ensured.

[0074] The cross-sectional shape of the guide part is shaped like the protective shell body, and the outer wall of the protective shell body is in surface contact, so that the stability is good.

[0075] The guide part of the utility model is preferably arc-shaped.

[0076] Further, the center position of the pressing wheel 31 is connected with the pressing wheel shaft 32; the pressing wheel shaft 32 of the two pressing wheels 31 of the same pressing wheel group is connected with the pressing wheel spring 33; the pulling force between the two pressing wheels 31 is generated through the pressing wheel spring 33, so that each group of buckling columns 51-buckling holes 52 can be completely buckled.

[0077] Each group of buckling columns 51 and buckling holes 52 is buckled in the pressing space, so that there is sufficient adjustment space between the buckling column 51 and the buckling hole 52, thereby correcting the deviation amount and ensuring the buckling quality.

[0078] Further, the buckling assembly 3 has a plurality of pressing wheel groups, and each pressing wheel group is sequentially arranged along the conveying direction. The pressing edge 53 of the protective shell sequentially passes through the pressing space of each pressing wheel group, thereby ensuring the buckling quality of all the buckle structures. Better, along the conveying direction, the spacing of the pressing spaces of each pressing wheel group of the utility model is sequentially reduced. Each group of buckling columns 51 and buckling holes 52 is sequentially pressed, thereby improving the quality consistency of the buckling step and ensuring the yield rate of buckling.

[0079] The sequential buckling device of the utility model sequentially buckles the first group of buckling columns 51-buckling holes 52 after folding the two half shells 5; then the buckling assembly 3 sequentially presses and buckles the buckling columns 51-buckling holes 52 of other groups. Each buckle structure is independently buckled and has sufficient adjustment space to correct the deviation amount, so that the yield rate of buckling is high and the consistency is good.

[0080] Referring to Figure 4 The utility model provides a kind of pipe shell mounting equipment with the sequential buckling device described above;It also includes feeding assembly arranged on one side of folding and pressing mechanism 1, for conveying flatly laid protective shell to folding and pressing mechanism 1;

[0081] The pipe body of seepage irrigation pipe passes above the two turnover blocks 11 and is inserted between the two pressing wheels 31 of the pressing wheel group of buckling assembly 3. The outer side of the pressing wheel 31 is arc-shaped; it is used to cover the pipe body, so that the pipe body is conveyed smoothly.

[0082] When the dripper on the pipe body travels above the two turnover blocks 11 or travels to have predetermined distance with the two turnover blocks 11, folding and pressing mechanism 1 and buckling assembly 2 act sequentially, fold the two half shells 5 of protective shell, and buckle the first group of buckling columns 51 and buckling holes 52. Then, with the advance of the pipe body, the dripper drives the protective shell to advance to buckling assembly 3, and in the process of passing through buckling assembly 3, all buckling columns 51 and buckling holes 52 of the protective shell are sequentially buckled, completing the installation of a protective shell. Feeding assembly subsequently sends a flatly laid protective shell to folding and pressing mechanism 1, waiting for the next installation operation.

[0083] The pipe body is continuously conveyed, and after each dripper reaches the predetermined position, the above-mentioned action is performed to complete the operation of sequentially installing protective shell on the dripper on the pipe body.

[0084] In order to improve the degree of automation, the conveying end of the buckling assembly 3 can be provided with a traction device, and the pipe body is continuously forwarded along the conveying direction to realize the installation of the protective shell of each drip head. In the initial stage, the pipe body can be manually pushed into and through the buckling assembly 3 and connected with the traction device. Then the traction device is started to automatically convey the pipe body.

[0085] The feeding assembly cooperates with the action of the folding and pressing mechanism 1 and the buckling assembly 2, and after the previous protective shell is folded and taken away by the pipe body, the feeding assembly sends a flat protective shell to the folding and pressing mechanism 1.

[0086] As an embodiment of the feeding assembly, the feeding assembly of the utility model comprises a conveying channel 4; the discharge end of the conveying channel 4 is connected to the two turnover blocks 11 of the folding and pressing mechanism 1, and the feeding end is provided with a feeding push cylinder 42.

[0087] The conveying channel 4 is previously filled with flat protective shells, and the feeding push cylinder 42 pushes all the protective shells on the conveying channel 4 to advance one shell position each time the feeding push cylinder 42 is extended, and sends one protective shell to the two turnover blocks 11 of the folding and pressing mechanism 1.

[0088] The skilled person in the art can adaptively set the stroke of the feeding push cylinder 42 to be equal to or slightly greater than the length of one protective shell, so that one protective shell is sent to the folding and pressing mechanism 1 each time the feeding push cylinder 42 is actuated.

[0089] Further, the upper part of the feeding end of the conveying channel 4 is provided with a vertically arranged discharging pipe 41; the discharging pipe 41 is provided with a discharging opening opposite to the feeding end of the conveying channel 4; the feeding push cylinder 42 pushes all the protective shells on the conveying channel 4 to advance one shell position, and after being retracted, one protective shell falls from the discharging opening of the discharging pipe 41 to the conveying channel 4. A plurality of protective shells are previously stacked in the discharging pipe 41, and the feeding push cylinder 42 supplements one protective shell to the conveying channel 4 each time the feeding push cylinder 42 is actuated. The conveying channel 4 is always maintained in a full position state.

[0090] As an embodiment of the seepage irrigation pipe protective shell installation device, a guide pipe 6 is further arranged above the discharge end of the conveying channel 4.

[0091] The pipe body is sent into the guide pipe 6 and directly conveyed to the upper part of the two turnover blocks 11 of the folding and pressing mechanism 1 after being guided out of the guide pipe 6. The conveying posture of the pipe body is standardized through the guide pipe 6, so that the pipe body can be accurately matched and installed with the protective shell.

[0092] In order to avoid interference, the feeding end of the conveying channel 4 is misaligned with the guide pipe 6. Further, the conveying channel 4 has two arc-shaped sections connected in sequence and opposite bending directions; the feeding end and the discharging end are respectively connected with the arc-shaped sections on the corresponding side. The feeding end is misaligned with the guide pipe 6 in the horizontal direction by a certain distance, so as to avoid interference between the pipe body and the conveying channel 4 or the discharging pipe 41. The discharging end is located directly below the guide pipe 6, so that the sleeve joint position of the protective shell and the pipe body is accurate.

[0093] Referring to Figure 10 As an embodiment of the drip irrigation pipe protective shell installation device, the guide pipe 6 is provided with a relief gap, and a detection assembly 7 extends into the relief gap from the relief gap;

[0094] The detection assembly 7 can be a contact switch, which abuts against the outer wall of the pipe body. When the dripper of the pipe body reaches, the contact switch is lifted by the pipe body, thereby sending a signal. The folding and pressing mechanism 1 and the pressing buckle assembly 2 act accordingly.

[0095] Since the difference between the diameter of the dripper and the diameter of the pipe body is small, in order to avoid false detection or missed detection, as an embodiment, referring to Figure 6 The detection assembly 7 of the utility model includes a fulcrum piece 72 that can rotate around a fixed center; one end of the fulcrum piece 72 is connected with a pipe pressing roller 71 extending into the relief gap, and the other end is connected with an amplification arm 73; one side of the amplification arm 73 is provided with a proximity switch 75;

[0096] The pipe pressing roller 71 abuts against the outer wall of the pipe body. When the dripper of the pipe body reaches, the pipe pressing roller 71 is lifted by a certain distance and drives the fulcrum piece 72 to rotate. The amplification arm 73 rotates accordingly and amplifies the lifting distance by several times, so that the amplification arm 73 approaches or moves away from the proximity switch 75, thereby making the proximity switch 75 send a signal to start the folding and pressing mechanism 1 and the pressing buckle assembly 2.

[0097] The length of the amplification arm 73 is at least three times the distance between the hub of the pipe pressing roller 71 and the fixed center, and is preferably 5-9 times. This ensures that the action amplitude of the amplification arm 73 can trigger the proximity switch 75 when the dripper reaches, avoiding missed detection.

[0098] More preferably, the end of the amplification arm 73 is connected with a tension spring 74; the tension spring 74 is always in a tension state, so that the pipe pressing roller 71 is pressed on the pipe body with a certain pressure, avoiding false detection caused by slight jumping of the pipe body during conveying.

[0099] ​The installation equipment of the seepage irrigation pipe protection shell is characterized in that the continuous conveying of the pipe body is realized, when the dripper reaches the predetermined position, the folding and pressing mechanism 1 of the sequential buckling device first acts to fold the two half shells 5 of the protection shell and buckle the first group of buckles, then the dripper drives the protection shell to move forward to the buckling assembly 3, and the buckling of the other buckles is sequentially completed, so that the protection shell is installed outside the dripper.

[0100] In conclusion, the folding and pressing mechanism is provided, and the turning block and the extruding part are synchronously rotated. In the folding process of the two half shells by the turning block, the two extruding parts are synchronously rotated to the extruding position with the turning block. When the two half shells are folded, the two extruding parts extrude the pressing edges of the half shells to complete the pressing connection of the buckling columns and the buckling holes. There is almost no delay between the two actions.
