Description

Technical Field

[0001] This utility model relates to the field of packaging bag manufacturing technology, and in particular to a sewing device for a gusseted bag. Background Technology

[0002] A self-sealing storage bag is a type of storage tool made by sewing ribs together at the opening of the bag. The ribs consist of a male strap and a female strap, which interlock using a convex-concave structure. During sewing, the male strap is sewn to the inside of the upper film of the storage bag, and the female strap is sewn to the inside of the lower film. By squeezing the male and female straps to close the ribs, the storage bag is sealed.

[0003] The drawbacks of traditional stitching machines for attaching bone bags are as follows: Both the storage bag and the bone strip are conveyed in the form of a conveyor belt. During material conveying, the upper and lower films of the storage bag are stacked together and fed to the separating blade via drive rollers. At the separating blade, the upper and lower films are spread apart to create space for the bone strip to be inserted. The bone strip enters the separating blade from below and from the outside of the storage bag. A guide slit on the separating blade (usually a 45° groove that switches the bone strip's transport direction from vertical to horizontal) guides the bone strip between the upper and lower films. Consequently, the bottom surface of the bone strip's base belt scrapes against the guide slit, causing wear and powdering. This not only weakens the bone strip's strength but also introduces waste material.

[0004] Therefore, it is necessary to improve the traditional stitching machine for bone bags to reduce the problem of wear caused by the bone strips being scraped at the separation knife. Utility Model Content

[0005] Based on this, the present invention provides a sewing device for attaching bone bags. Utilizing a reversing wheel assembly and a transmission roller, the bone strip is guided from one side of the storage bag. Then, a first and second guiding module aligns the bone strip and separates the storage bag, thereby achieving stacking of the storage bag and bone strip. This design eliminates the guide cut of the traditional separating knife, reducing the risk of scratching the bottom surface of the bone strip's base and mitigating wear caused by scratching at the separating knife.

[0006] A suturing device for a bone patch, comprising:

[0007] Reversing wheel assembly;

[0008] Drive roller;

[0009] The first guiding module includes: a guide shaft, and a first limiting ring and a second limiting ring respectively sleeved on the guide shaft;

[0010] The second guiding module includes: a base plate, a limiting plate connecting the base plate, and a film-separating blade connecting the base plate; the limiting plate is located between the guide shaft and the film-separating blade, and the limiting plate is provided with a first guide groove; the film-separating blade is provided with a second guide groove on the same straight line as the first guide groove; when the storage bag is guided to the film-separating blade by the drive roller, the film-separating blade opens the storage bag, so that the upper film of the storage bag passes through the top surface of the film-separating blade, and the lower film of the storage bag passes through the bottom surface of the film-separating blade; when the rib passes through the reversing wheel group and the drive roller in sequence from the outside of the storage bag, it achieves the first guidance between the first limiting ring and the second limiting ring, then the rib achieves the second guidance through the first guide groove, and then the rib passes into the second guide groove, thereby inserting itself between the upper and lower films of the storage bag; and

[0011] Sewing module; The sewing module is used to sew together the storage bag and bone strips after they have been separated by the membrane cutter.

[0012] In the aforementioned sewing device for the bone bag, during operation, the storage bag is guided by a drive roller to a separating blade, which separates the upper and lower films. The bone strip is guided by a reversing wheel set to the drive roller, and is introduced from one side of the storage bag at an angle. Then, it passes through a first and second guiding module for lateral alignment, ensuring the bone strip is straightened. The separating blade then guides the bone strip between the upper and lower films of the storage bag, thus stacking the storage bag and bone strip. Finally, the sewing module performs the sewing process. This design utilizes a reversing wheel set and drive rollers to introduce the bone strip from one side of the storage bag, followed by alignment and separation of the storage bag by the first and second guiding modules, achieving the stacking of the storage bag and bone strip. This design eliminates the traditional guiding cut of the separating blade, reducing the risk of scratching the bottom surface of the bone strip's base and mitigating wear caused by scratching at the separating blade.

[0013] In one embodiment, both the first limiting ring and the second limiting ring are slidably configured. The first limiting ring is provided with a first adjustable screw, and the second limiting ring is provided with a second adjustable screw, both of which are radially arranged along the guide shaft. The first and second limiting rings can be unlocked and their spacing adjusted by tightening or loosening the first and second adjustable screws according to the width of different bone strips, thereby adapting to the current width of the bone strip. This design offers high flexibility, versatility, and simple operation.

[0014] In one embodiment, the film separating blade includes: a first blade connecting to a substrate and a second blade detachably connected to the first blade; a second guide groove is located on either the first or the second blade. The first and second blades cooperate to form a structure that clamps the ribs from above and below, and the detachable design facilitates the loading operation of the ribs.

[0015] In one embodiment, the suturing device for the bone graft bag further includes: a base, a frame slidably mounted on the base, a driver connected to the frame, and a correction photoelectric sensor connected to the frame; a second guiding module and a suturing module are both mounted on the frame; the correction photoelectric sensor is located between a guide shaft and a limiting plate; the driver is used to drive the frame to move laterally; the correction photoelectric sensor, the second guiding module, and the suturing module all move synchronously with the frame. The correction photoelectric sensor can detect whether the current trajectory of the bone strip has deviated from the preset trajectory. If so, the driver drives the frame to move laterally, thereby correcting the trajectory of the bone strip.

[0016] In one embodiment, the first guiding module is mounted on the rack and moves synchronously with the rack. The first guiding module, which moves synchronously with the rack, can reduce the risk of misalignment between the guiding directions of the first and second guiding modules due to the offset of the second guiding module during the correction process.

[0017] In one embodiment, the sewing module includes two sewing components symmetrically arranged vertically. Each sewing component includes a fixed plate, multiple guide wheels mounted on the fixed plate, a belt mounted on the guide wheels, a heating blade slidably mounted on the fixed plate, and a cooling blade slidably mounted on the fixed plate. The two symmetrically arranged sewing components can simultaneously perform heat-press sewing of the upper film and male belt, and the lower film and female belt, respectively, resulting in high work efficiency. Furthermore, cooling is performed after heat-press sewing to improve molding efficiency.

[0018] In one embodiment, at least one guide wheel has a sliding adjustable structure to facilitate adjustment of the belt tension. Attached Figure Description

[0046] Example 1

[0047] like Figures 1 to 7 As shown, it is a sewing device 100 for a bone-attaching bag according to an embodiment of the present invention.

[0048] like Figure 1 As shown, the suture device 100 for the bone graft bag includes: a reversing wheel assembly 10, a drive roller 20, a first guide mold assembly 30, a second guide mold assembly 40, and a suture module 50. Figure 7 As shown, during operation, the reversing wheel assembly 10 guides the ribs 300. The drive roller 20 guides the storage bag 200 and the ribs 300. The first guiding module 30 corrects the direction of the ribs 300, and the second guiding module 40 corrects the direction of the ribs 300 a second time, so that the transmission direction of the ribs 300 is consistent with the transmission direction of the storage bag 200. Furthermore, the second guiding module 40 also guides the ribs 300 between the upper and lower films of the storage bag 200. The sewing module 50 performs the sewing process on the storage bag 200 and the ribs 300 after passing through the film separating knife 43.

[0049] The following text, combined with Figures 1 to 7 The above-mentioned suture device 100 for the bone-attaching bag will be further described.

[0050] like Figure 1 As shown, based on the design of the transmission path of the rib 300, the reversing wheel assembly 10 may include multiple reversing wheels to perform single or multiple reversing transmissions of the direction of the rib 300. Figure 1 For example, in this embodiment, the reversing wheel assembly 10 includes: a first reversing wheel 11 and a second reversing wheel 12, combined with... Figure 7 As shown, the bone strip 300 is adjusted to be horizontally transmitted by the first reversing wheel 11, and then adjusted to be vertically transmitted by the second reversing wheel 12. It is then guided to the transmission roller 20, and the bone strip 300 is adjusted to be horizontally transmitted again by the transmission roller 20.

[0051] like Figure 1 As shown, in this embodiment, the transmission roller 20 is a driven roller shaft, and for ease of adjustment, it is provided with a height-adjustable support structure. Figure 7As shown, during operation, the transmission roller 20 is used not only to conduct the storage bag 200, but also to conduct the rib 300. Therefore, based on the trajectory of the storage bag 200, the rib 300 needs to be introduced from one side of the storage bag 200.

[0052] like Figure 2 As shown, in this embodiment, the first guiding module 30 includes a guide shaft 31, and a first limiting ring 32 and a second limiting ring 33 respectively sleeved on the guide shaft 31. A channel is formed between the first limiting ring 32 and the second limiting ring 33 for the bone strip 300 to pass through. When the bone strip 300 passes through the guide shaft 31, the first limiting ring 32 and the second limiting ring 33 limit both sides of the bone strip 300. In addition, in this embodiment, the guide shaft 31 is parallel to the transmission roller 20, and in order to facilitate the adjustment of the transmission trajectory of the bone strip 300, one end of the guide shaft 31 is mounted on the swing arm 34. By adjusting the swing angle of the swing arm 34, the height of the guide shaft 31 can be adjusted.

[0053] Furthermore, such as Figure 2 As shown, in this embodiment, both the first limiting ring 32 and the second limiting ring 33 are slidably configured. The first limiting ring 32 is provided with a first adjustable screw 321, and the second limiting ring 33 is provided with a second adjustable screw 331, both of which are radially arranged along the guide shaft 31. Depending on the width of different bone strips 300, the first limiting ring 32 and the second limiting ring 33 can be unlocked and their spacing adjusted by tightening or loosening the first adjustable screw 321 and the second adjustable screw 331, thereby adapting to the current width of the bone strip 300. This provides high flexibility, versatility, and simple operation. Furthermore, after unlocking the first limiting ring 32 and the second limiting ring 33, the trajectory of the bone strip 300 can be adjusted by sliding the positions of the first limiting ring 32 and the second limiting ring 33.

[0054] like Figures 3 to 5 As shown, in this embodiment, the second guiding module 40 includes: a substrate 41, a limiting plate 42 connecting the substrate 41, and a separating blade 43 connecting the substrate 41. The limiting plate 42 is located between the guide shaft 31 and the separating blade 43, and the limiting plate 42 is provided with a first guide groove 421. The separating blade 43 is provided with a second guide groove 431 located on the same straight line as the first guide groove 421.

[0055] In this design, the membrane splitting knife 43 is different from the traditional design. Instead of setting a guide cut to reverse the transmission of the bone strip 300, the membrane splitting knife 43 corrects the direction of the bone strip 300 from the oblique cutting direction to a straight line direction consistent with the transmission direction of the storage bag 200 by setting a second guide groove 431 that cooperates with the first guide groove 421.

[0056] like Figure 5As shown, in this embodiment, the film separating blade 43 may include: a first blade 432 connected to the substrate 41 and a second blade 433 detachably connected to the first blade 432. The second guide groove 431 is located on the first blade 432 or the second blade 433. The first blade 432 and the second blade 433 cooperate to form a structure in which the upper and lower clamping strips 300 are arranged. The detachable design facilitates the loading operation of the clamping strips 300.

[0057] When the storage bag 200 is guided by the transmission roller 20 to the film separating knife 43, the film separating knife 43 opens the storage bag 200, so that the upper film of the storage bag 200 passes through the top surface of the film separating knife 43, and the lower film of the storage bag 200 passes through the bottom surface of the film separating knife 43.

[0058] After the rib 300 passes through the reversing wheel group 10 and the transmission roller 20 from the outside of the storage bag 200, it is first guided between the first limiting ring 32 and the second limiting ring 33. Then, the rib 300 is guided for the second time through the first guide groove 421. Then, the rib 300 passes into the second guide groove 431 and is inserted between the upper and lower films of the storage bag 200.

[0059] In this solution, the suturing module 50 can be either ultrasonic suturing or thermal suturing. Taking thermal suturing as an example, such as... Figure 6 As shown, in this embodiment, the sewing module 50 includes two sewing components 51 arranged symmetrically vertically. Each sewing component 51 includes a fixing plate 511, multiple guide wheels 512 mounted on the fixing plate 511, a belt 513 mounted on the guide wheels 512, a heating blade 514 slidably mounted on the fixing plate 511, and a cooling blade 515 slidably mounted on the fixing plate 511. The two symmetrically arranged sewing components 51 can simultaneously perform heat-press sewing of the upper film and male belt, and the lower film and female belt, respectively, resulting in high work efficiency. Furthermore, cooling is performed after heat-press sewing to improve molding efficiency.

[0060] Furthermore, in this embodiment, at least one guide wheel 512 has a sliding adjustable structure, which facilitates the adjustment of the tension of the belt 513.

[0061] Brief description of working principle:

[0062] like Figure 7As shown, during operation, the storage bag 200 is guided by the film separating knife 43 via the drive roller 20, and the upper and lower films are separated by the film separating knife 43. The rib 300 is guided by the drive roller 20 via the reversing wheel group 10 and is introduced into the storage bag 200 from one side in an inclined posture. Then, the rib 300 is laterally guided by the first guiding module 30 and the second guiding module 40 in sequence, so that the rib 300 is guided into a straight posture consistent with the forward trajectory of the storage bag 200. Then, the rib 300 is introduced into the space between the upper and lower films of the storage bag 200 by the film separating knife 43, thereby completing the stacking of the storage bag 200 and the rib 300. Finally, the sewing module 50 performs the sewing process.

[0063] Furthermore, to improve the alignment accuracy of the storage bag 200 and the bone strip 300 during sewing, a mechanism for monitoring the trajectory of the bone strip 300 can be set up. Based on the boundary of the overlapping area between the storage bag 200 and the bone strip 300, it can be determined whether the trajectory of the bone strip 300 needs to be laterally shifted to correct the offset. For example, as... Figure 1 As shown, in this embodiment, the suturing device 100 for the bone graft bag may further include: a base 60, a frame 70 slidably mounted on the base 60, a driver 80 connected to the frame 70, and a correction photoelectric sensor 90 connected to the frame 70. The second guiding module 40 and the suturing module 50 are both mounted on the frame 70. The correction photoelectric sensor 90 is located between the guide shaft 31 and the limiting plate 42. The driver 80 is used to drive the frame 70 to move laterally. The correction photoelectric sensor 90, the second guiding module 40, and the suturing module 50 all move synchronously with the frame 70. The correction photoelectric sensor 90 can detect whether the current trajectory of the bone strip 300 has deviated from the preset trajectory. If so, the driver 80 drives the frame 70 to move laterally, thereby correcting the trajectory of the bone strip 300.

[0064] Furthermore, such as Figure 1 As shown, in this embodiment, the first guide module 30 is installed at the shaft of the transmission roller 20. When the frame 70 shifts laterally, there will be a relative shift between the first guide module 30 and the second guide module 40, resulting in a misalignment between them. Here, it is considered that in actual operation, the correction amplitude of the rib 300 is usually within 2mm. Therefore, even if the second guide module 40 shifts laterally along with the frame 70, it will not seriously affect the operation of the correction photoelectric sensor 90, that is, it is still within an acceptable range.

[0065] The aforementioned stitching device 100 for attaching bone bags utilizes a reversing wheel assembly 10 and a transmission roller 20 to guide the bone strips 300 from one side of the storage bag 200. Then, the first guiding module 30 and the second guiding module 40 guide the bone strips 300 and separate the film from the storage bag 200, thereby achieving the stacking of the storage bag 200 and the bone strips 300. This design eliminates the guide cut of the traditional film-separating knife 43, reducing the risk of scratching the bottom surface of the mother tape of the bone strips 300 and mitigating the wear caused by scratching the bone strips 300 at the film-separating knife 43.

[0066] Example 2

[0067] like Figure 8 As shown, this is a sewing device 100 for a bone-attaching bag according to another embodiment of the present invention.

[0068] The difference between this embodiment and Embodiment 1 is that, for the scenario mentioned in Embodiment 1 where the rack 70 needs to be laterally offset, the misalignment problem that may occur between the first guiding module 30 and the second guiding module 40 due to lateral offset is optimized and improved. For example... Figure 8 As shown, in this embodiment, the first guiding module 30 is mounted on the frame 70 and moves synchronously with the frame 70. The first guiding module 30, which moves synchronously with the frame 70, can reduce the risk of misalignment between the guiding directions of the first guiding module 30 and the second guiding module 40 due to the offset of the second guiding module 40 during the correction process.

[0069] The other structures in this embodiment are the same as in Embodiment 1, and it can also achieve the beneficial effects of Embodiment 1.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
