Description

Technical Field

[0001] The utility model relates to the technical field of agricultural production binding tools, in particular to a branch binding machine with three-layer binding belts. Background Art

[0002] When planting crops such as tomatoes, grapes, and kiwis, we usually need to fix the vines or branches of the plants on bamboo racks or wires to guide their growth or assist in fruiting, thereby increasing crop yield and quality. In order to improve the efficiency of branch tying, compared to the traditional use of ropes for branch tying, operators now usually use branch tying machines (also called baling machines) to tie and fix the plants.

[0003] For example, CN107517773A discloses a branch binding machine, including a holding member, a holding member force unit, a locking member, and a locking member force unit. The holding member force unit is a torsion spring that applies a force on the holding member that has a counterclockwise rotation tendency, and the locking member engages with the holding member to keep the holding member in a standby position; the locking member force unit is a compression spring that applies a force on the locking member that has a clockwise rotation tendency.

[0004] CN211210728U discloses a branch binding machine, which mainly includes a binding strap clamping device, a bow frame, a handle, a frame, a needle box, and a binding strap box. The positioning plate is hinged in the machine box cavity, and a spring is provided on the positioning plate to enable it to have a tendency to rotate in the counterclockwise direction; the pressing needle is hinged in the machine box cavity, and a torsion spring is also provided on the pressing needle to enable it to have a tendency to rotate in the counterclockwise direction; the positioning plate matches the pressing needle.

[0005] However, the existing branch binding machine has the following shortcomings: after the binding is completed, the existing branch binding machine obtains the binding effect of two layers of binding tape, such as Fig.17 As shown, its disadvantage is that the end of the upper strap (second layer L2) is too long, which can easily cause waste. In addition, the binding nails are relatively sharp and can easily pierce the upper strap (second layer L2). When the wind blows and pulls, the upper strap (second layer L2) can be easily punctured and the nails can be pulled off, causing the strap TP to fail in binding the branches.

[0006] In view of the shortcomings of the above-mentioned prior art, the purpose of the utility model is to provide a branch binding machine with three layers of binding straps. By reasonably arranging the protruding length of the end of the clamping plate relative to the end of the forming anvil and providing a binding strap anti-slip mechanism, a stable three-layer binding effect can be obtained. Utility Model Content

[0007] The utility model provides a branch binding machine capable of nailing three layers of binding tapes, which solves the problem that the branch binding machine in the prior art can only obtain the binding effect of two layers of binding tapes after completing the binding, which easily causes the binding tapes to fail.

[0008] The utility model solves the above-mentioned technical problems as follows: a branch binding machine for nailing three layers of binding straps, comprising a clamping device, a bow frame, a handle, a frame, a needle box and a binding strap box, wherein the rear end of the bow frame is hinged on the frame, and a handle is provided between the bow frame and the frame; a clamping device is provided at the front end of the bow frame, and the clamping device can clamp the binding strap from the front end of the frame, and the clamping device comprises: a machine box, a hook head, a clamping plate, and a forming anvil, the hook head is hinged in the cavity of the machine box, the forming anvil is arranged at the lower end of the machine box, and a clamping plate is arranged between the hook head and the forming anvil; the protruding length of the end of the clamping plate relative to the end of the forming anvil is less than or equal to 1.9 mm.

[0009] Preferably, a strap anti-slip mechanism is provided in the box body of the strap box.

[0010] Preferably, the strap anti-slip mechanism comprises a spring frame, and a strap anti-slip platform and a spring fixing platform are provided on the box body of the strap box, one end of the spring frame is fixed on the spring fixing platform, and the other end is pressed and fitted with the strap anti-slip platform.

[0011] Preferably, the spring frame is in the shape of a bent rectangular frame including a horizontal section and an inclined section, and a notch is provided at the end of the horizontal section; the end of the inclined section is pressed tightly against the strap anti-slip platform, and the strap is located between the end of the inclined section and the strap anti-slip platform.

[0012] Preferably, the spring fixing platform comprises a spring U-shaped groove and a fixing screw hole, the horizontal section of the spring frame is placed in the spring U-shaped groove, and the fixing bolt passes through the horizontal section of the spring frame and is connected to the fixing screw hole.

[0013] Preferably, a slot is provided on the spring fixing platform, and the horizontal portion of the spring frame extends into the slot and is engaged with the slot.

[0014] Preferably, the strap anti-slip platform and the spring fixing platform are integrally formed with the box body of the strap box.

[0015] The utility model provides a branch binding machine with three-layer binding tapes, which has the following advantages:

[0016] 1. In order to ensure sufficient length of the strap and prevent the strap from returning to the strap box, a spring frame is provided in the box body of the strap box. The spring frame is in the shape of a bent rectangular frame and includes a horizontal section and an inclined section. The horizontal section is fixed in the spring U-shaped groove of the spring fixing platform. The end of the inclined section and the strap anti-slip platform are clamped to prevent the strap from sliding.

[0017] 2. Setting the protruding length of the end of the clamping plate relative to the end of the forming anvil to be less than or equal to 1.9 mm can obtain a stable three-layer strapping binding effect; if the protruding length is too long, the third layer of the strap will easily slide relative to the second layer of the strap during the binding process, thereby causing the third layer of the strap to move out of the position between the second layer of the strap and the forming anvil; in addition, if the protruding length is too long, the residual length of the strap after cutting (the third layer of the strap) will not be able to cover the forming anvil, thereby failing to complete the binding of the three-layer strap.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0050] like Figure 1-2 As shown, a branch binding machine with three layers of binding tape provided in an embodiment of the utility model includes a clamping device 1, a bow frame 2, a handle 3, a frame 4, a needle box 5 and a binding tape box 6, the cross section of the frame 4 is "U"-shaped; the rear end of the bow frame 2 is hinged to the frame 4, a handle 3 is provided between the bow frame 2 and the frame 4, the handle 3 and the bow frame 2 are hingedly arranged on the frame 4 in an "x" shape; a clamping device 1 is provided at the front end of the bow frame 2, the clamping device 1 can clamp the binding tape from the front end of the frame 4, the clamping device 1 clamps the binding tape TP and then pulls it out, and then the binding tape TP is wrapped around the branch to be bound for binding.

[0051] After the binding is completed, the binding machine of the prior art obtains the binding effect of two layers of binding tape, such as Fig.17 As shown, the disadvantage is that the end of the second layer L2 is too long, which may cause waste. In addition, the binding nails are relatively sharp and may easily pierce the second layer L2, causing the binding strap TP to fail to bind the branches.

[0052] In order to complete the binding of the three-layer strap, it is necessary to reserve sufficient strap TP length. After the strap TP is drawn out from the strap box 6, it passes through the impact block 412. In order to ensure sufficient strap length, it is also necessary to prevent the strap TP from returning to the strap box 6; Figure 3-4 As shown, in order to prevent the strap from sliding back, a strap anti-slip mechanism is provided in the box body of the strap box 6; the strap anti-slip mechanism includes a spring frame 61, and in addition, a strap anti-slip platform 62 and a spring fixing platform 63 are provided on the box body of the strap box 6, the strap anti-slip platform 62 is used to cooperate with the spring frame 61, and the spring fixing platform 63 is used to fix the spring frame 61. One end of the spring frame 61 is fixed on the spring fixing platform 63, and the other end is pressed and matched with the strap anti-slip platform 62, and the strap TP passes through the spring frame 61 and the spring fixing platform 63; the spring frame 61 is a bent rectangular frame including a horizontal section 612 and an inclined section 613, and correspondingly, the spring fixing platform 63 includes a spring U-shaped groove 631 and a fixing screw hole 632, and the horizontal section 612 of the spring frame 61 is placed in the spring U-shaped groove 631, and the fixing bolt passes through the horizontal section 612 of the spring frame 61 and is connected with the fixing screw hole 632, and the fixing bolt passes through the hollow part of the horizontal section 612 and is threadedly connected with the fixing screw hole 632, relying on the fixing The spring frame 61 is fixed to the spring fixing platform 63 by bolts; in order to prevent the horizontal section 612 from being unable to be placed in the spring U-shaped groove 631, a notch 611 is provided at the end of the horizontal section 612, so that the horizontal section 612 has a certain deformation ability, even if the width of the horizontal section 612 is different from the width of the spring U-shaped groove 631, the horizontal section 612 can be easily placed in the spring U-shaped groove 631; the end of the inclined section 613 is pressed and fitted with the strap anti-slip platform 62, and the strap is located between the end of the inclined section 613 and the strap anti-slip platform 62, and the strap is prevented from sliding by the clamping effect of the end of the inclined section 613 and the strap anti-slip platform 62.

[0053] Another method for fixing the spring frame 61 is to provide a slot on the spring fixing platform 63 , and the horizontal portion of the spring frame 61 extends into the slot and is engaged with the slot.

[0054] Furthermore, in order to facilitate production, the strap anti-slip platform 62 and the spring fixing platform 63 can be integrally formed with the box body of the strap box 6 .

[0055] like Figure 5-6As shown, the clamping device 1 includes a machine box 11, a torsion spring 12, a hook head 13, a clamping plate 14, a forming anvil 15 and a compression spring 16. The machine box 11 is a cavity structure. The torsion spring 12, the hook head 13, the clamping plate 14, the forming anvil 15 and the compression spring 16 are all arranged in the cavity of the machine box 11. The hook head 13 is hinged in the cavity of the machine box 11. The hook head 13 is also connected to the torsion spring 12 and the compression spring 16 that make it have a clockwise movement tendency. The forming anvil 15 is arranged at the lower end of the machine box 11, and the clamping plate 14 is arranged between the hook head 13 and the forming anvil 15.

[0056] In order to complete the binding of the three-layer strap, it is necessary to strictly set the extension length D of the end of the clamping plate 14 relative to the end of the forming anvil 15, such as Figure 14-15 As shown, if the extended length D is too long, the third layer L3 will easily slide relative to the second layer L2 during the binding process, thereby causing the third layer L3 to move out of the position between the second layer L2 and the forming anvil 15. In addition, if the extended length D is too long, the residual length of the strap after cutting (the third layer L3) cannot cover the forming anvil 15, thereby failing to complete the binding of the three-layer strap. After multiple verifications, the application sets the extended length D of the end of the clamping plate 14 relative to the end of the forming anvil 15 to: D≤1.9mm, which can obtain a stable three-layer strap binding effect. Fig.16 As shown (the specific binding process of the strap is as follows Figure 12-15 shown).

[0057] like Figure 7 As shown, the hook head 13 includes a pressure block 131, a belt grabbing groove 132, a positioning groove 133, a top block 134 and a compression spring positioning head 135. The belt grabbing groove 132 is opened at the bottom of the hook head 13, the pressure block 131 is arranged on the left side of the hook head, the top block 134 is arranged on the right side of the hook head 13, the positioning groove 133 and the compression spring positioning head 135 are arranged on the upper part of the hook head 13, the lower end of the compression spring 16 is sleeved on the compression spring positioning head 135, and the upper part of the compression spring 16 is fixedly connected to the machine box 11.

[0058] A first hinge axis A1 and a second hinge axis A2 are fixedly arranged in the cavity of the machine box 11, the torsion spring 12 is fixedly sleeved on the first hinge axis A1, and the hook head 13 is rotatably sleeved on the second hinge axis A2. When one end of the torsion spring 12 is inserted into the positioning groove 133, the three points of the positioning groove 133-A1-A2 form a triangular structure. Furthermore, when the end of the torsion spring 12 is inserted into the positioning groove 133, the hook head 13 can be locked.

[0059] When the hook head 13 rotates clockwise downward, it contacts the clamping plate 14 to achieve the action of grabbing the strap. In order to increase the friction force when the hook head 13 grabs the strap, a spherical protrusion is provided on the surface of the clamping plate 14, and a concave-convex pattern is provided on the surface of the clamping groove 132. When the clamping groove 132 at the bottom of the hook head 13 cooperates with the spherical protrusion, the gripping force on the strap can be increased. In addition, the compression spring 16 acts on the hook head 13. When the hook head 13 rotates clockwise, the compression force of the hook head 13 on the clamping plate 14 can be increased under the action of the compression spring 16, and the gripping force on the strap can be further increased when the clamping groove 132 cooperates with the spherical protrusion.

[0060] The handle 3 is composed of a handle frame 31 and a plastic grip 32. The handle frame 31 is embedded in the plastic grip 32. In order to improve the grip friction, a silicone anti-skid pad is provided on the upper surface of the plastic grip 32. The anti-skid pad can be made of silicone. When there is no external force, the bow frame 2 is kept in the open position relative to the frame 4 (such as Figure 1 By pressing the handle 3, the bow frame 2 rotates relative to the frame 4, so that the front end of the bow frame 2 contacts the frame 4, and the bow frame 2 is in the closed position (as shown in FIG. Figure 8 shown).

[0061] like Figure 8-11 As shown, a cutter 411 and a striking block 412 are provided at the front end of the frame 4, the cutter 411 is fixedly connected to the frame 4, and the striking block 412 is hinged to the frame 4; the striking block 412 cooperates with the pressing block 131 and the top block 134 on the hook head 13; the strap TP is led out from the strap box 6 and passes through the striking block 412, and when the bow frame 2 rotates in the closing direction relative to the frame 4, the striking block 412 contacts the pressing block 131 to make the hook head 13 rotate clockwise, thereby making the end of the torsion spring 12 disengage from the positioning groove 133, thereby releasing the locking state of the hook head 13; when the bow frame 2 rotates in the closing direction relative to the frame 4 again, the striking block 412 contacts the top block 134 to make the end of the torsion spring 12 fit into the positioning groove 133, thereby completing the locking of the hook head 13.

[0062] In addition, a needle outlet 51 is provided at the front end of the needle box 5, and a needle pressing head 53 is provided at the bottom of the needle outlet 51. A spring 52 is provided between the lower surface of the needle box 5 and the frame 4. The rear end of the needle box 5 is hinged to the frame 4, and the forming anvil 15 of the clamping device 1 cooperates with the needle outlet 51; when the front end of the needle box 5 is subjected to the downward force of the forming anvil 15, it can be rotated downward relative to the frame 4, and the needle pressing head 53 pushes the staplers in the needle box 5 out, and the staplers bind the straps under the action of the forming anvil 15 (the binding principle is similar to that of a stapler); after the force disappears, under the action of the spring 52, the needle box 5 rotates upward to the initial position relative to the frame 4.

[0063] Working principle:

[0064] The branch binding machine includes standby state, belt grabbing state, branch binding state, and binding and belt cutting state, which are as follows:

[0065] Standby state: Combined Figure 1-3 , as shown in 12, where Figure 1-2 This is the standby state of the branch tying machine before tying, in which the position of the bow frame 2 relative to the frame 1 is in the open position. Figure 5 1 is a structural diagram of the corresponding clamping device 1. In the standby state, the hook head 13 is in a locked position, its front end is kept separated from the clamping strip 14, and the end of the torsion spring 12 is inserted into the positioning groove 133 of the hook head 13. The corresponding strap state, such as Fig.12 As shown, the strap TP is led out from the strap box 6 and passes through the impact block 412. The strap TP exposed outside the impact block 412 is the third layer L3, and the strap TP located inside the impact block 412 is the second layer L2.

[0066] Grab belt status: combined Figure 6 ,8-9,12, based on Figure 2 The bow frame is in the open state, and by squeezing the handle 3 to apply force, the bow frame 2 rotates downward in the clockwise direction relative to the frame 4; Figure 8 As shown, as the bow frame 2 rotates until the clamping device 1 contacts the front end of the frame 4, at this time, the impact block 412 contacts the pressure block 131, and the impact block 412 applies a clockwise force to the hook head 13, and the end of the torsion spring 12 slides out of the positioning groove 133 of the hook head 13. The hook head 13 rotates clockwise under the pressure of the torsion spring 12 and the pressure spring 16. At this time, the hook head 13 contacts the clamping plate 14, and a spherical protrusion is provided on the surface of the clamping plate 14. The spherical protrusion cooperates with the gripping groove 132 to clamp the strap TP. The corresponding strap state is as follows: Fig.12 As shown, the second layer L2 and the third layer L3 of the binding strap TP are both inserted between the spherical protrusion and the strap gripping groove 132 .

[0067] Binding status: combined Figure 9-10 , as shown in 14-15, after the hook head 13 clamps the strap TP, the pressing force on the handle 3 is released and the bow frame 2 rotates upward in the counterclockwise direction. As the bow frame 2 rotates, the strap TP is stretched; Fig.10 As shown, after the branch binding machine is deeply inserted into the position of the branch to be bound, the binding belt TP is made to surround the branch to complete the branch binding; the corresponding binding belt state is as follows Figure 14-15As shown, the second layer L2 and the third layer L3 of the strap TP are both inserted between the spherical protrusion and the strap gripping groove 132, the branches are located between the first layer L1 and the second layer L2 of the strap TP, and the third layer L3 extends along the clamping plate 14 and the forming anvil 15. Only when the third layer L3 completely covers the forming anvil 15 can a stable three-layer strap structure be obtained after the strap is bound.

[0068] Binding and cutting status: combined Figure 10-11 As shown in Figure 16, after the binding is adjusted to a suitable position for the branch, the handle 3 is pressed, and the bow frame 2 moves downward again until the clamping device 1 contacts the front end of the frame 4, and the handle 3 is further pressed, the forming anvil 15 contacts the front end of the needle box 5. Under the pressure of the forming anvil 15, the needle box 5 rotates downward to make the needle pressing head 53 press the stapler out of the needle outlet 51 and contact the forming anvil 15 to complete the binding of the binding TP; at the same time, the impact block 412 contacts the arc segment at the lower end of the hook head 13 and rotates clockwise until it contacts the top block 134. As the impact block 412 rotates clockwise, the cutter 411 is exposed, and the binding TP is cut by the cutter 411; then, the impact block 412 continues to press the top block 134 until the end of the torsion spring 12 is stuck in the positioning groove 133 to achieve the locking of the hook head 13, and the binding and cutting of the binding are completed; after the binding is completed, as shown in Figure 16 Fig.16 As shown, a three-layer binding effect is obtained. Subsequently, the handle 3 is released, the bow frame 2 returns to the open position again, and the hook head 13 returns to the standby state. In this way, a branch binding operation is completed, and the above actions can be repeated to achieve the branch binding operation of various branches.

[0069] like Figure 16-17 As shown, compared with the two-layer binding of the prior art, the utility model folds the end of the second layer L2 into the third layer L3, thereby avoiding waste. In addition, it is difficult for the binding nails to penetrate the second layer L2 and the third layer L3 at the same time, which can prevent the binding strap TP from failing and improve its binding timeliness for the branches.
