Description

Technical Field

[0001] This utility model relates to the technical field of storage bag production equipment, and in particular to a bone strip feeding detection device for bone bags. Background Technology

[0002] A snap-lock bag is a type of storage bag with a sealable opening. It consists of a bag body and a snap-lock mechanism at the opening. The snap-lock mechanism includes male and female strips that interlock (a convex-concave snap-lock structure, also known as male and female snaps). The male strip is located on one inner wall of the bag body, while the female strip is located on the other inner wall. When the user presses on the opening of the bag body, the male and female strips are squeezed together to lock in place, thus creating a seal.

[0003] When making the ribbed bag, the pre-made bag body and ribs are fed to the sewing equipment, where they are sewn together (e.g., by heat pressing). In actual production, if the ribs become knotted during feeding, it can lead to failure in sewing the bag body and ribs, or even cause the ribs to break and damage equipment parts.

[0004] Therefore, it is necessary to develop a bone strip feeding detection device that can not only detect whether the bone strip is knotted during feeding, but also issue a stop signal before the bone strip is about to break due to knotting. Utility Model Content

[0005] Based on this, the present invention provides a bone strip feeding detection device for bone bags, which uses a first detection module to detect whether there is knotting and a second detection module to detect whether there is jamming. It can not only detect whether the bone strip is knotted during feeding, but also issue a stop signal before the bone strip is about to break due to knotting.

[0006] A bone strip feeding detection device for bone bags includes:

[0007] support;

[0008] A first detection module for connecting the bracket; the first detection module includes: a first guide wheel, a knot detection component, and a second guide wheel respectively mounted on the bracket; the knot detection component includes: a fixed roller shaft connecting the bracket, a dynamic pressure wheel arranged parallel to the fixed roller shaft, a mounting base connecting the dynamic pressure wheel, a slide block slidably connected to the mounting base, a return spring located between the mounting base and the slide block, and a first position sensor located on the mounting base; the slide block is mounted on the bracket; the mounting base is provided with a first trigger plate matching the first position sensor; and

[0009] The second detection module of the connecting bracket includes: a third guide wheel, a jamming detection component, and a fourth guide wheel respectively installed on the bracket; the jamming detection component includes: a movable pulley of the sliding connecting bracket and a second position sensor of the connecting bracket; the movable pulley is slidably arranged in the vertical direction; the movable pulley is provided with a second trigger piece that matches the second position sensor.

[0010] The aforementioned bone strip feeding detection device for bone bags, when the bone strip enters the first detection module, uses the first and second guide wheels for trajectory orientation. Then, if there are knots on the bone strip due to tangling, when the knot passes the fixed roller, it forces the dynamic pressure roller to deviate, triggering the first position sensor. The first position sensor generates an alarm electrical signal to the control panel of the sewing equipment. When the bone strip enters the second detection module, it is guided by the third guide wheel, the movable pulley, and the fourth guide wheel. Then, if the bone strip gets stuck due to tangling during input, the front end of the bone strip moves forward under the drive mechanism of the sewing equipment, while the rear end cannot move forward due to the sticking. This causes the movable pulley to be lifted by the bone strip, triggering the second position sensor, which generates a stop electrical signal to the control panel of the sewing equipment. Through this design, the first detection module detects the presence of knots, and the second detection module detects the presence of sticking. This not only detects whether knots occur during bone strip feeding but also issues a stop signal before the bone strip is about to break due to tangling.

[0011] In one embodiment, the first guide wheel is slidably connected to the bracket and locked in a preset position by a first positioning screw; the slide is slidably connected to the bracket and locked in a preset position by a second positioning screw. Depending on the thickness of the rib strip, the positions of the first guide wheel and the slide can be adjusted adaptively by operating the positioning screw and sliding.

[0012] In one embodiment, the mounting base has a first slide rod and a second slide rod arranged laterally; both the first and second slide rods pass through the slide block; a return spring is sleeved on the first slide rod; and a first trigger plate is disposed at the end of either the first or second slide rod. The first and second slide rods cooperate to limit the sliding trajectory of the mounting base, the return spring sleeved on the first slide rod improves the stability of the installation, and the first trigger plate can move synchronously with either the first or second slide rod. The structure is simple and the operation is highly stable.

[0013] In one embodiment, the second detection module further includes: a lifting seat connected to the movable pulley, a lifting guide rod passing through the lifting seat, and a fixed seat connected to the lifting guide rod; the lifting guide rod is arranged in a vertical direction; and the fixed seat is connected to a bracket. Through the cooperation of the lifting seat, the lifting guide rod, and the fixed seat, the movable pulley can slide vertically up and down, resulting in a simple structure and strong operational stability.

[0014] In one embodiment, the second detection module further includes a counterweight basket connected to the lifting seat; the counterweight basket is used to hold counterweight blocks. The counterweight basket is used to adjust the tension of the ribs required for the movable pulley to disengage from a preset position.

[0015] In one embodiment, the bone strip feeding and detection device for the bone bag further includes: a secondary pressing module for the bone strips connected to the support; the secondary pressing module for the bone strips is located before the first detection module and the second detection module; the secondary pressing module for the bone strips includes: a driven pressure roller connected to the support, an active pressure roller arranged parallel to the driven pressure roller, and a rotary motor connected to the active pressure roller. The secondary pressing module for the bone strips allows for secondary pressing of the male and female bone strips, ensuring that the male and female strips are already snapped together before entering subsequent processes, reducing the risk of misjudgment in product defect or knot detection.

[0016] In one embodiment, the driven pressure roller is slidably connected to the bracket and locked in a preset position by a third positioning screw. Depending on the thickness of the rib strips, the position of the driven pressure roller can be adjusted adaptively by operating the positioning screw and sliding it. Attached Figure Description

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0037] like Figures 1 to 7 As shown, it is a bone strip feeding detection device 100 for a bone-attaching bag according to an embodiment of the present invention.

[0038] like Figure 1 As shown, the bone strip feeding detection device 100 for the bone bag includes: a support 10, a first detection module 20 connected to the support 10, and a second detection module 30 connected to the support 10. Figure 6As shown, the bracket 10 is used to support the first detection module 20 and the second detection module 30. The first detection module 20 is used to detect whether there is a knot (i.e., a node) in the bone strip 200 during feeding, and the second detection module 30 is used to detect whether the bone strip 200 is stuck due to knots during feeding.

[0039] It should be further explained that although the first detection module 20 can detect the presence of knots, the rib 200 may get stuck before even entering the first detection module 20 (i.e., the knots of the rib 200 are already stuck at the feeding point before entering the first detection module 20). Therefore, in this solution, a second detection module 30 is specifically set up. That is, when the rib 200 has small to medium knots, the rib 200 will not get stuck, and this can be detected by the first detection module 20. When the rib 200 has large knots, the rib 200 may already be stuck at the feeding port, and this can be detected by the second detection module 30.

[0040] The following text, combined with Figures 1 to 7 The bone strip feeding detection device 100 for the bone bag described above will be further explained.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the bracket 10 is welded from a metal tube. In other embodiments, the bracket 10 may also be cut from a metal plate. In this solution, the specific shape and structure of the bracket 10 are not limited.

[0042] like Figure 1 As shown, the first detection module 20 includes: a first guide wheel 21, a knot detection component 22, and a second guide wheel 23, all mounted on the bracket 10. Figure 3 As shown, the knot detection assembly 22 includes: a fixed roller shaft 221 connecting to the bracket 10; a dynamic pressure roller 222 arranged parallel to the fixed roller shaft 221; a mounting base 223 connecting to the dynamic pressure roller 222; a slide block 224 slidably connected to the mounting base 223; a return spring 225 located between the mounting base 223 and the slide block 224; and a first position sensor 226 located on the mounting base 223. The slide block 224 is mounted on the bracket 10, and the mounting base 223 is provided with a first trigger piece 2231 that matches the first position sensor 226. See here for more details. Figure 7 In this embodiment, the first guide wheel 21 and the second guide wheel 23 are respectively arranged vertically, so that the bone strip 200 passes through the knot detection component 22 in a vertical state, while the sliding direction of the mounting base 223 is horizontal. If the bone strip 200 has a knot and passes between the fixed roller 221 and the dynamic pressure roller 222, the knot will push the dynamic pressure roller 222 to shift laterally (to... Figure 7For example, when the node of the bone strip 200 passes the fixed roller 221, it will force the dynamic pressure roller 222 to shift to the left, thereby triggering the first position sensor 226 for detecting the preset zero position of the dynamic pressure roller 222.

[0043] Since the knot detection component 22 determines whether there are knots in the bone strip 200 by detecting changes in the thickness of the bone strip 200, the zero position of the knot detection component 22 needs to be adjusted for different thicknesses of the bone strip 200. Therefore, in this embodiment, the first guide wheel 21 is slidably connected to the bracket 10 and locked in a preset position by a first positioning screw (not shown). The slide block 224 is slidably connected to the bracket 10 and locked in a preset position by a second positioning screw 227. According to different thicknesses of bone strips 200, the positions of the first guide wheel 21 and the slide block 224 can be adjusted for adaptation by operating the positioning screw and sliding. For example, as Figure 2 As shown, in this embodiment, the bracket 10 is provided with a first oblong hole 11 connected to the first positioning screw, and a second oblong hole (not shown) connected to the second positioning screw 227.

[0044] In addition, in order to improve the operational stability of the dynamic pressure roller 222, such as Figure 3 As shown, in this embodiment, the mounting base 223 is provided with a first slide rod 2232 and a second slide rod 2233 arranged horizontally. Both the first slide rod 2232 and the second slide rod 2233 pass through the slide block 224. A return spring 225 is sleeved on the first slide rod 2232. A first trigger piece 2231 is disposed at the end of either the first slide rod 2232 or the second slide rod 2233. The first slide rod 2232 and the second slide rod 2233 cooperate to limit the sliding trajectory of the mounting base 223. The return spring 225 sleeved on the first slide rod 2232 improves the stability of the installation, and the first trigger piece 2231 can move synchronously with either the first slide rod 2232 or the second slide rod 2233. The structure is simple and the movement is highly stable.

[0045] like Figure 1 As shown, the second detection module 30 includes: a third guide wheel 31, a jamming detection component 32, and a fourth guide wheel 33, all mounted on the bracket 10. Figure 4 and Figure 5As shown, the jamming detection component 32 includes: a movable pulley 321 of the sliding connecting bracket 10 and a second position sensor 322 of the connecting bracket 10. The movable pulley 321 is slidably arranged in the vertical direction, and the movable pulley 321 is provided with a second trigger piece 3211 that matches the second position sensor 322. In this embodiment, the third guide wheel 31 and the fourth guide wheel 33 are symmetrically arranged about the central axis of the movement trajectory of the movable pulley 321. The bone strip 200 passes through the third guide wheel 31, the movable pulley 321, and the fourth guide wheel 33 in sequence, forming a V-shaped trajectory. When the bone strip 200 jams at any position before the movable pulley 321, it will force the movable pulley 321 to rise, thereby triggering the second position sensor 322 used to detect the preset zero position of the movable pulley 321.

[0046] To improve the operational stability of the movable pulley 321, in this embodiment, the second detection module 30 further includes: a lifting seat 323 connecting the movable pulley 321, a lifting guide rod 324 passing through the lifting seat 323, and a fixed seat 325 connecting the lifting guide rod 324. The lifting guide rod 324 is arranged vertically. The fixed seat 325 is connected to the bracket 10. Through the cooperation of the lifting seat 323, the lifting guide rod 324, and the fixed seat 325, the movable pulley 321 can slide vertically up and down, resulting in a simple structure and strong operational stability.

[0047] Furthermore, considering that the suture strip 200 advances under the pulling action of the drive mechanism in the suturing equipment, tension will exist on the suture strip 200 even if jamming does not occur. To facilitate operators in adjusting the tension of the suture strip 200 when a jamming condition is triggered, a counterweight structure can be configured on the second detection module 30. For example, in some embodiments, the second detection module 30 may also include a counterweight basket connected to the lifting seat 323. The counterweight basket is used to hold counterweight blocks. The counterweight basket is used to adjust the tension of the suture strip 200 required for the movable pulley 321 to disengage from a preset position.

[0048] Brief description of working principle:

[0049] like Figure 6 As shown, when the bone strip 200 enters the first detection module 20, the first guide wheel 21 and the second guide wheel 23 are used for trajectory orientation.

[0050] like Figure 7As shown, if there are knots on the rib 200 due to knotting, when the knots pass the fixed roller 221, the knots will force the dynamic pressure roller 222 to shift, thereby triggering the first position sensor 226. The first position sensor 226 generates an alarm electrical signal to the control panel of the suturing equipment. When the rib 200 enters the second detection module 30, it is guided by the third guide wheel 31, the movable pulley 321, and the fourth guide wheel 33. Then, if the rib 200 gets stuck due to knotting during input, the front end of the rib 200 moves forward under the drive mechanism of the suturing equipment, while the rear end of the rib 200 cannot move forward because it is stuck. This causes the movable pulley 321 to be lifted up by the rib 200, thereby triggering the second position sensor 322. The second position sensor 322 generates a stop electrical signal to the control panel of the suturing equipment.

[0051] Based on the above working principle, it can be seen that in this solution, the order in which the first detection module 20 and the second detection module 30 are set is not restricted. That is, the bone strip 200 can enter the first detection module 20 first and then the second detection module 30. Alternatively, the bone strip 200 can enter the second detection module 30 first and then the first detection module 20.

[0052] Additionally, considering the risk of male and female strips becoming detached at the feeding point, therefore, if... Figure 1 and Figure 2 As shown, in this embodiment, the bone strip feeding detection device 100 for the bone bag further includes a secondary bone strip pressing module 40 connected to the support 10. The secondary bone strip pressing module 40 is located before the first detection module 20 and the second detection module 30. The secondary bone strip pressing module 40 includes a driven pressure roller 41 connected to the support 10, an active pressure roller 42 arranged parallel to the driven pressure roller 41, and a rotary motor 43 connected to the active pressure roller 42. The secondary bone strip pressing module 40 can perform secondary pressing on the male and female strips of the bone strip 200, ensuring that the male and female strips are already snapped together before entering subsequent processes, reducing the risk of misjudgment in product defect or knot detection.

[0053] Furthermore, also considering the different thicknesses of the rib strips 200, in this embodiment, the driven pressure roller 41 is slidably connected to the bracket 10 and locked in a preset position by a third positioning screw (not shown). Depending on the different thicknesses of the rib strips 200, the position of the driven pressure roller 41 can be adjusted adaptively by operating the positioning screw and sliding. For example, as... Figure 2 As shown, the bracket 10 is provided with a third oblong hole 12 that connects to the third positioning screw.

[0054] The bone strip feeding detection device 100 for the aforementioned bone bag uses a first detection module 20 to detect whether there is knotting and a second detection module 30 to detect whether there is jamming. It can not only detect whether the bone strip 200 is knotted during feeding, but also issue a stop signal before the bone strip 200 is about to break due to knotting.

[0055] 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.

[0056] 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.
