[0040] Reference below Figures 1 to 10 The invention describes a binding mechanism and a binding machine according to an embodiment of the invention.

[0041] like Figures 1 to 4As shown, the tying mechanism according to the embodiment of the utility model includes a nail guide assembly 200, a nail feeding assembly, a forming mold assembly 400, a closing assembly 600, and a pushing assembly. The nail guide assembly 200 is provided with a nail sliding channel 201, and the two sides of the nail sliding channel 201 are respectively provided with first guide grooves 202 corresponding to the side parts of the nails, and one side of the nail guide assembly 200 is provided with a notch 203 connected to the nail sliding channel 201; the nail feeding assembly is connected to the nail guide assembly 200 and can feed the nails into the nail sliding channel 201; the forming mold assembly 400, the closing assembly 600, and the pushing assembly. Component 400 is arranged on the guide nail assembly 200 and is located at one end of the nail piercing sliding channel 201; the closing component 600 can be rotatably connected to the guide nail assembly 200, and the closing component 600 is provided with a second guide groove 601. The closing component 600 can be rotated to close the gap 203 and align the second guide groove 601 with the first guide groove 202; the pushing component includes a driving mechanism and a pushing component 520 that can be slidably arranged on the nail piercing sliding channel 201. The driving mechanism can drive the closing component 600 to rotate and drive the pushing component 520 to slide in the nail piercing sliding channel 201.

[0042] When in use, the closing component 600 can close the gap 203, and fill the missing guide structure of the nail sliding channel 201 in the gap 203 through the second guide groove 601, so that the nail can slide to the forming mold component 400 with high precision, so that the nail can stably and reliably complete the deformation bundling, thereby improving the success rate of tying.

[0043] Specifically, the bag is placed into the nail sliding channel 201 from the notch 203, the driving mechanism drives the pushing piece 520 to move, pushing the nail in the nail sliding channel 201, the driving mechanism drives the closing assembly 600 to rotate and close the notch 203 to limit the displacement of the bag, and at the same time fills the missing guide structure of the nail sliding channel 201 in the notch 203, when the open end of the U-shaped nail passes through the bag, the binding part of the bag is placed in the U-shaped nail, and finally the driving mechanism drives the pushing piece 520 to push the nail to the forming mold assembly 400, guided by the bending groove 401 on the forming mold assembly 400, the two ends of the U-shaped nail are bent close to each other, thereby tightening the bag opening.

[0044] like Figure 8 , Fig.10 , Fig.11 As shown, in some embodiments of the present invention, the closing assembly 600 closes the gap 203, and the second guide groove 601 is aligned with the first guide groove 202, thereby achieving precise guidance of the nail.

[0045] like Fig.11 As shown, in some embodiments of the present invention, the closing assembly 600 is formed by stacking a plurality of plate members, and the plate member in the middle is set to be narrower, thereby forming the second guide groove 601, and the manufacturing process is simple.

[0046] It can be understood that in some embodiments of the present invention, the closing component 600 may also be a single part, and the second guide groove 601 is formed by machining.

[0047] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, in some embodiments of the present invention, the guide nail assembly 200 is formed by stacking a plurality of plate members, and the plate member in the middle is set to be narrower, thereby forming the first guide groove 202, and the manufacturing process is simple.

[0048] It can be understood that in some embodiments of the present invention, the guide nail assembly 200 can also be a single part, and the first guide groove 202 is formed by machining.

[0049] like Figure 1 , Figure 2 As shown, in some embodiments of the present invention, the tying mechanism further includes a frame 100 , wherein the nail guide assembly 200 and the pushing assembly are both disposed on the frame 100 .

[0050] It can be understood that in some embodiments of the present invention, the nail guide assembly 200 or the pushing assembly can also be used as a frame for installing other components of the tying mechanism.

[0051] like Figure 7 As shown, in some embodiments of the present invention, one end of the closing component 600 is rotatably mounted to the guide nail component 200 via the rotating shaft 610 , and the closing component 600 is connected to the driving mechanism at a position deviating from the rotating shaft 610 .

[0052] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments of the present invention, the frame 100 is provided with a slide 110, the slide 110 is provided with a slideway 111 that slides with the push piece 520, and the lower end of the push piece 520 is provided with a driving part 521, and the driving mechanism includes a first connecting rod 511, a second connecting rod 512, a third connecting rod 513, a fourth connecting rod 514, and a handle 515, wherein the handle 515 is rotatably mounted to the frame 100, one end of the first connecting rod 511 is fixed to the rotating shaft of the handle 515, the other end of the first connecting rod 511 is hinged to one end of the second connecting rod 512, and the other end of the second connecting rod 512 is divided into The third link 513 and the fourth link 514 are hinged to one end of the third link 513 and one end of the fourth link 514, the other end of the fourth link 514 is hinged to the frame 100, and the other end of the third link 513 is hinged to the driving part 521. The third link 513, the fourth link 514 and the frame 100 form a triangular link structure. When the second link 512 moves up to push the triangular link structure to deform, since the other end of the fourth link 514 is hinged to the frame 100, a fixed hinge point is formed, so that the third link 513 drives the driving part 521 and the pushing member 520 to be pushed outward, thereby meeting the driving requirements of the pushing member 520.

[0053] It can be understood that in some embodiments of the present invention, the driving mechanism may also be driven by a motor, that is, the handle 515 may be replaced by a motor drive assembly.

[0054] In addition, in some embodiments of the present invention, the driving mechanism may also use a linear driving mechanism such as a cylinder or an electric cylinder to drive the pushing member 520 to be pushed out or retracted.

[0055] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of the utility model, a cross arm 522 is extended from the side wall of the driving portion 521, and the cross arm 522 is connected to the closing component 600 through a rod group, so that the closing component 600 and the pushing member 520 move synchronously. When the pushing member 520 pushes, the closing component 600 is synchronously driven to close the gap 203 and connect the nail sliding channel 201.

[0056] It is understandable that in some embodiments of the present invention, the closing component 600 may also be configured with an independent driving mechanism, and the closing component 600 and the pushing member 520 may be controlled to move synchronously through the control component.

[0057] In some embodiments of the present invention, an elastic connection mechanism 530 is provided between the closing component 600 and the driving mechanism to elastically push the closing component 600 to improve safety.

[0058] Specifically, since the bag needs to be put into the gap 203 manually, when an error operation occurs, the rigid push-closed closing component 600 can easily cause pinching injuries to the user. The utility model has a certain anti-pinch function by pushing the closing component 600 through the elastic connection mechanism 530.

[0059] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the elastic connection mechanism 530 is a telescopic tube, and a spring is disposed inside the telescopic tube.

[0060] Specifically, the elastic connection mechanism 530 includes an inner tube and an outer tube sleeved inside the inner tube. A compression spring is arranged between the inner tube and the outer tube. The outer tube acts on the inner tube through the compression spring, thereby elastically pushing the inner tube. The inner tube and the outer tube are respectively connected to the closing component 600 and the driving mechanism, thereby satisfying the function of elastically pushing the closing component 600.

[0061] like Figure 7 and Fig. 9 As shown, in some embodiments of the present invention, the nail delivery assembly includes a positioning seat 310 arranged on the guide nail assembly 200 and a guide rod 320 inserted in the positioning seat 310, and a storage channel 321 capable of stacking nails is arranged in the guide rod 320, and the positioning seat 310 is provided with an insertion groove 311 connected to the nail sliding channel 201 and capable of inserting the guide rod 320, and the nails at the lower end of the storage channel 321 can fall from top to bottom into the nail sliding channel 201, thereby realizing a continuous supply of nails.

[0062] Specifically, the positioning seat 310 is vertically installed on the nail guide assembly 200, and the guide rod 320 can be inserted into the positioning seat 310 from top to bottom, so that the nails can be continuously input into the nail sliding channel 201 by gravity.

[0063] like Figure 7 and Fig. 9 As shown, in some embodiments of the present invention, a guide rod seat 330 is arranged between the positioning seat 310 and the guide nail assembly 200, and the guide rod seat 330 is provided with a connecting channel 331 corresponding to the storage channel 321, the upper end of the connecting channel 331 is connected to the storage channel 321, and the lower end of the connecting channel 331 is connected to the nail sliding channel 201, and the nails sent out from the lower end of the guide rod 320 enter the nail sliding channel 201 through the connecting channel 331 of the guide rod seat 330. The guide rod seat 330 is installed to the guide nail assembly 200, is not affected by the bouncing of the guide rod 320, and can maintain the stable docking of the connecting channel 331 and the nail sliding channel 201, thereby improving the stability and reliability of the nails pushed in the nail sliding channel 201.

[0064] Specifically, the stapler has a structure similar to that of a stapler, and multiple staples are stacked and bonded together in sequence. The pushing piece 520 can push out the lowest staple. Since the driving mechanism has a certain impact force, it is very easy to cause the guide rod 320 to jump, affecting the docking between the lower end opening of the storage channel 321 of the guide rod 320 and the staple sliding channel 201, and it is easier for the staples to be pushed off-center or multiple staples to be pushed out at one time. By configuring the guide rod seat 330 with the connecting channel 331, the connecting channel 331 maintains a stable docking with the staple sliding channel 201. Even if the guide rod 320 jumps, the impact on the staples that have entered the connecting channel 331 is less, thereby improving the stability and reliability of the staples pushed in the staple sliding channel 201.

[0065] In some embodiments of the present invention, the cross-section of the connecting channel 331 is consistent with that of the storage channel 321 and corresponds to the pinning to keep the pinning in place.

[0066] It can be understood that in some embodiments of the present invention, the guide rod seat 330 can be configured as an integrated structure with the positioning seat 310, or the guide rod seat 330 and the guide nail assembly 200 can be configured as an integrated structure.

[0067] In some embodiments of the present invention, the distance from the lower edge of the connecting channel 331 to the bottom wall of the nail sliding channel 201 is greater than or equal to the thickness of a single nail and less than twice the thickness of the nail, thereby reducing the situation of pushing out multiple nails at one time and improving the reliability of the nailing.

[0068] like Fig. 9 As shown, in some embodiments of the present invention, the guide rod seat 330 is provided with a limiting step 332 that cooperates with the lower end of the guide rod 320 to support and position the guide rod 320.

[0069] like Figure 5 , Figure 6 , Figure 7 As shown, in some embodiments of the present invention, a side portion of the guide rod 320 is provided with a spring-pressing structure 322 that can be spring-pressed to the slot wall of the insertion slot 311 to improve the stability of the guide rod 320 when inserted into the insertion slot 311 .

[0070] Specifically, the spring pressing structure 322 is a spring sheet disposed on the side of the guide rod 320 .

[0071] It can be understood that in some embodiments of the present invention, the elastic pressure structure 322 can also be a rubber pad or the like.

[0072] In some embodiments of the present invention, the forming die assembly 400 can be detachably mounted on the guide nail assembly 200 to facilitate replacement and maintenance of the forming die assembly 400 .

[0073] Specifically, Figure 7As shown, the molding die assembly 400 is mounted to the guide nail assembly 200 via a clamping structure.

[0074] Of course, in a specific implementation process, the forming die assembly 400 can also be installed to the guide nail assembly 200 through a screw mechanism.

[0075] like Fig.11 As shown, in some embodiments of the present invention, the forming die assembly 400 is provided with two staggered bending grooves 401, and the two bending grooves 401 are distributed on both sides of the corresponding nailing sliding channel 201, so that the two ends of the nailing are staggered and bent to achieve a better tying effect.

[0076] Specifically, Fig.11 As shown, the bending groove 401 corresponding to the second guide groove 601 of the closing component 600 extends obliquely upward, guiding one of the legs of the nail to bend obliquely upward, and the bending groove 401 corresponding to the other side of the nail sliding channel 201 extends obliquely downward, guiding the other leg of the nail to bend obliquely downward, thereby causing the two ends of the nail to be bent in an offset manner.

[0077] The sealing machine according to the second aspect of the utility model includes the sealing mechanism of any one of the first aspect of the utility model, which can improve the success rate of packaging bag bundling and sealing and has a better use effect.

[0078] Of course, the invention of the present invention is not limited to the above-mentioned implementation modes. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
