Description

Technical Field

[0001] This utility model relates to the field of bag-shooting machine technology, specifically, to a bag-shooting machine. Background Technology

[0002] Early material packaging relied heavily on manual operations such as bag placement and filling. With the expansion of industrial production and the growth of automation needs, bag injection machines gradually emerged. Their development has gone through a process from simple mechanical structures to complex mechatronic systems. The initial bag injection machines had relatively simple functions, only able to complete basic bag conveying and placement. Later, they gradually integrated a variety of advanced technologies, such as sensor detection and PLC control, to achieve a higher degree of automation and intelligence, thus enabling more accurate and efficient bag injection operations.

[0003] Bag inserting machines, also known as bag insertion machines, are now widely used automated equipment in the packaging industry. They use a conveying system to transport bags from the storage location to the insertion location, and use gripping and spreading devices to precisely insert the bags into the filling port of the packaging equipment for filling.

[0004] Patent CN210503409U discloses a bag-picking mechanism. Although the bag-picking mechanism is equipped with a position sensor, unexpected positional deviations of the bag-picking support rod still occur in actual production. Due to the lack of a limiting structure, the bag-picking support rod or other components may be damaged by impact, which may also lead to safety accidents. Therefore, further improvements are needed to the bag-picking mechanism to avoid unnecessary losses when the bag-picking support rod is unexpectedly deviated. Utility Model Content

[0054] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0055] like Figure 1 The diagram shows the structure of a bag injection machine, which mainly consists of a bag-feeding mechanism 100, a feeding mechanism 200, and a bag-inserting mechanism 300. In operation, the packaging bags are first placed on the bag-feeding mechanism 100 for temporary storage. Then, the feeding mechanism 200 organizes the bags, preventing duplicate packing or stacking, and simultaneously detects and corrects the bag positions to improve consistency. Depending on actual needs, the bag-inserting mechanism 300 seals and shapes the bags, while planning the insertion path. Once the bag is inserted, the bag-inserting mechanism 300 detects the completion signal and provides feedback. Through the combined operation of the bag-feeding mechanism 100, the feeding mechanism 200, and the bag-inserting mechanism 300, the packaging bags are transported to the insertion position, ready for material filling.

[0056] like Figures 2-9 As shown, this utility model proposes a feeding mechanism 200 for a bag injection machine, including a mounting frame 1, which has a guide positioning groove 2; a bag taking rotating frame 3 is rotatably mounted on the mounting frame 1, and the guide positioning groove 2 is located on one side of the bag taking rotating frame 3; a limiting member 4 is movable along the guide positioning groove 2 and is used to block the bag taking rotating frame 3.

[0057] In this embodiment, in order to solve the problem of the lack of limit when the bag-removing support rod 33 accidentally deviates in the related technology, causing unnecessary losses, a limit member 4 is installed on the mounting frame 1. The limit member 4 is used to block the bag-removing rotating frame 3 from deviating in position unexpectedly. The limit member 4 can move along the guide positioning groove 2 to adjust its position. The position point to be limited is set according to the actual production situation.

[0058] Specifically, the mounting frame 1 serves as the basic support structure, providing a stable mounting position for components such as the bag-picking rotating frame 3 and the limiting component 4. Its guide positioning groove 2 not only provides a precise guiding path for the movement of the limiting component 4, ensuring that it does not shift or wobble during movement, but also allows for flexible adjustment of the limiting component 4's blocking position on the bag-picking rotating frame 3 according to different working stages or feeding requirements of the bag-shooting machine, preventing excessive rotation and feeding errors.

[0059] Furthermore, the mounting bracket 1 also has a guide positioning groove 2 5, located on one side of the guide positioning groove 2, with the openings of the guide positioning groove 2 5 and the guide positioning groove 2 aligned. It also includes a tooth 6, which is disposed within the guide positioning groove 2. The tooth 2 7 is rotatably disposed within the guide positioning groove 2 5. The rotating member 8 is rotatably disposed on the limiting member 4, with the rotation axis of the rotating member 8 parallel to the rotation axis of the bag-retrieving rotating frame 3. The rotating member 8 is located between the guide positioning groove 2 5 and the guide positioning groove 2, and has a tooth 3 9 on it, which meshes with both the tooth 3 9 and the tooth 6 and the tooth 2 7. The support member 10 is disposed on the limiting member 4, located below the rotating member 8, and rests on the inner walls of the guide positioning groove 2 5 and the guide positioning groove 2.

[0060] In this embodiment, in order to make the movement of the limiting member 4 more stable and smooth when it moves along the guide positioning groove 1 2, a tooth 1 6 and a tooth 2 7 are also provided. A freely rotatable rotating member 8 is installed on the limiting member 4. The meshing structure of the tooth 3 9 and the tooth 1 6 and tooth 2 7 converts rotation into movement, which makes the movement of the limiting member 4 more stable and smooth during the movement process, and avoids jamming or slippage.

[0061] The support component 10 plays an important supporting and stabilizing role. It shares part of the weight and external force borne by the limiting component 4 during movement and operation, reduces the friction and wear between the limiting component 4 and the guide positioning groove 2, and extends the service life of the component.

[0062] In addition, under the support of the support member 10, due to the self-locking characteristic of the meshing of the teeth, when the limiting member 4 moves to a specific position and stops, the rotating member 8 will also stop rotating and remain in the current position, thereby effectively fixing the position of the limiting member 4 and preventing it from being displaced when subjected to external interference (such as vibration, collision, etc.), thus improving the positioning accuracy and reliability of the limiting member 4.

[0063] Furthermore, the guide positioning groove 12 has several slots 11 located below the toothed part 6, and also includes a moving part 12. The moving part 12 is movably disposed on the limiting part 4, located between the rotating part 8 and the supporting part 10. The moving direction of the moving part 12 is parallel to the rotation axis of the rotating part 8. The moving part 12 has a protrusion 13, which is used to be locked in the slot 11. One end of the elastic part 14 acts on the moving part 12, and the other end acts on the supporting part 10, for providing the protrusion 13 of the moving part 12 to be locked in the slot 11.

[0064] In this embodiment, to facilitate locking and unlocking after the limiting member 4 moves to the designated position, a protrusion 13 and a slot 11 are used. When the protrusion 13 of the moving member 12 engages with the slot 11, the limiting member 4 is firmly fixed in the current position. This positioning method has high accuracy and stability and can effectively resist the influence of external interference factors on the position of the limiting member 4. The elastic member 14 can be a spring. The elastic member 14 provides a continuous driving force for the protrusion 13 to engage with the slot 11, ensuring that the protrusion 13 will not easily disengage from the slot 11 under normal working conditions. When the position of the limiting member 4 needs to be adjusted, simply apply an appropriate external force to press down the limiting member 4, overcome the elastic force of the elastic member 14, and cause the protrusion 13 to disengage from the slot 11. This allows the limiting member 4 to be easily moved to a new position. Then, release the external force, and the protrusion 13 will re-engage into the corresponding slot 11 under the action of the elastic member 14. This achieves rapid adjustment and precise positioning of the limiting member 4, greatly improving the ease of operation for adjusting the position of the limiting member 4.

[0065] In addition, when the rotating part 8 moves with the limiting part 4, due to the small amount of movement, its third tooth 9 will not disengage from the first tooth 6 and the second tooth 7, but will only move relative to each other, which effectively avoids the situation where the third tooth 9 disengages from the first tooth 6 and the second tooth 7, resulting in the inability to re-engage.

[0066] Furthermore, both guide positioning groove 25 and guide positioning groove 12 are annular or arc-shaped.

[0067] In this embodiment, this shape design allows the limiting member 4 to move along a circular or arc-shaped trajectory during movement, matching the rotation trajectory of the bag-picking rotating frame 3. This provides more flexible and continuous adjustment of the blocking position of the bag-picking rotating frame 3, allowing for precise setting at any position within a 360-degree or certain arc range, thus meeting the complex and diverse blocking requirements of the bag-picking rotating frame 3 during the bag-feeding process of the bag-shooting machine.

[0068] Furthermore, it also includes a rotary drive 15, connected to the bag-retrieving rotating frame 3, for driving the bag-retrieving rotating frame 3 to rotate; a cylinder 16, the cylinder body of which is mounted on the bag-retrieving rotating frame 3; a bracket 17 driven by the cylinder 16 to move up and down; a bag-retrieving detection plate one 18 and a bag-retrieving detection plate two 19, both of which are mounted on the bag-retrieving rotating frame 3; and a bag-retrieving position sensor 20 located below the bag-retrieving detection plate one 18 and the bag-retrieving detection plate two 19.

[0069] In this embodiment, the bag-retrieving rotating frame 3 is driven to rotate by the rotating drive component 15. A cylinder 16 is provided on the bag-retrieving rotating frame 3, which can drive the bracket 17 to move up and down. The bag-retrieving rotating frame 3 has a bag-retrieving detection plate 18 and a bag-retrieving detection plate 29. A bag-retrieving position sensor 20 is provided below the bag-retrieving detection plate 18 and the bag-retrieving detection plate 29. It is set on the ground and does not rotate with the bag-retrieving rotating frame 3. It can detect the position, thereby realizing accurate judgment of the front and back position of bag retrieval, ensuring accurate, efficient and automatic operation. The positions of the bag-retrieving detection plate 18 and the bag-retrieving detection plate 29 are judged twice. At the same time, the bracket 17 can also be used as a third bag-retrieving detection plate to realize position detection by sensing it through the bag-retrieving position sensor 20. Multiple detections effectively avoid the occurrence of false detections.

[0070] Furthermore, it also includes a frame 21; a transverse guide 22 is disposed on the frame 21; a movable frame 23 is slidably disposed on the transverse guide 22, and a rotary drive 15 is disposed on the movable frame 23; a drive cylinder 24 has its cylinder body disposed on the frame 21, and drives the movable frame 23 to move laterally.

[0071] In this embodiment, the movable frame 23 slides on the transverse guide 22, thereby driving the rotary drive device and its driven bag-picking rotary frame 3 to move and adjust in the transverse direction, thus ensuring a wider bag-picking working range. The movable frame 23 and the drive cylinder 24 are more convenient and effective.

[0072] Furthermore, it also includes a mounting frame 1, which is a circular plate and is mounted on the rotary drive 15 or the moving frame 23. Several concentric arc-shaped holes 26 are formed on it, and the bag-taking position sensor 20 is mounted on the arc-shaped holes 26. The bag-taking position sensor 20 includes position sensor 27, position sensor 28 and position sensor 29, which are sequentially mounted on the mounting frame 1.

[0073] Furthermore, a vertical guide 30 is provided on the bag-taking rotating frame 3, and a guide block 31 is provided on the bracket 17. The guide block 31 is slidably disposed on the vertical guide 30.

[0074] The bracket 17 includes a support plate 32 that is driven by a cylinder 16 to move up and down, and a plurality of parallel bag-removing support rods 33 are provided on the support plate 32.

[0075] Furthermore, it also includes a second mounting bracket 34, which is mounted on the output shaft of the rotary drive 15. The second mounting bracket 34 is corner-shaped, and the first bag detection plate 18 and the second bag detection plate 19 are respectively mounted on the two sides forming the corner.

[0076] In this embodiment, the mounting frame 1 is a circular plate that does not rotate. It is mounted on the rotary drive 15 or the movable frame 23, and has several concentric arc-shaped holes 26. The bag-removing position sensor 20 is mounted on the arc-shaped holes 26. The several concentric arc-shaped holes 26 can not only install more position sensors for position detection, but also have different diameters, so the entire circular plate is not separated, making the structure more stable. The structure will not be unstable due to the arc-shaped holes 26 being a single, large arc. The bag-removing position sensor 20 includes a position sensor 27, a position sensor 28, and a position sensor 29, which are sequentially mounted on the mounting frame 1. The three sensors 29 and the corresponding bag-picking detection plates 18, 19, and 17 serve as position detection devices. Rotating to the starting and ending positions enables dual detection by two sensors corresponding to two detection plates, thus ensuring excellent overall accuracy and stability. The cylinder 16 is designed as a rodless cylinder, making better use of space. The bracket 17 includes a support plate 32 driven by the cylinder 16 to move up and down. The support plate 32 is equipped with several parallel bag-picking struts 33, which are very stable and can work well with the cement bags picked up from the bag-picking mechanism, enabling bag picking operations without the need for a complex robotic arm.

[0077] Furthermore, it also includes a rotating ring 35, which is rotatably disposed in the guide positioning groove 5, and has a rectangular groove 36 on the rotating ring 35; one end of the connecting rod 37 is disposed on the moving part 12, and the other end is located in the rectangular groove 36 and has the same outline as the rectangular groove 36.

[0078] In this embodiment, in order to ensure that the protrusion 13 on the moving member 12 can be smoothly inserted into the corresponding slot 11 when the limiting member 4 moves, the moving member 12 is connected to a freely rotatable rotating ring 35 by a connecting rod 37. When the limiting member 4 moves, it is similar to a revolution. When the moving member 12 rotates, the protrusion 13 can also be adjusted in angle under the action of the connecting rod 37 and the rotating ring 35 to correspond well to the slots 11 at different positions. The design of the rectangular slot 36 avoids the relative movement between the connecting rod 37 and the rotating ring 35 after the protrusion is inserted into the slot 11, which would prevent the limiting member 4 from being fixed. With the rectangular slot 36, the other end of the connecting rod 37 cannot move relative to the rotating ring 35 when the protrusion is inserted into the slot 11, which can effectively fix the limiting member 4.

[0079] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
