Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a pin assembly. Background Technology

[0002] In the packaging industry, gusseted bags, due to their unique three-dimensional structure and excellent display effect, have gradually become the preferred choice for packaging various granular and strip-shaped products. In the production process of gusseted bags, the accurate and efficient insertion of the gussets is a crucial step in ensuring the quality of the packaging bags. However, traditional gusset insertion methods have many shortcomings, limiting the improvement of production efficiency for gusseted bags.

[0003] Traditionally, inserting the prongs into pouches was done manually. This method is not only inefficient but also labor-intensive, making it difficult to meet the demands of modern industrial production. Especially in high-speed, high-volume production, manual operation is not only too slow but also prone to problems such as inaccurate prong placement and damage to the packaging bag, seriously affecting product quality and production efficiency.

[0004] Different products have varying requirements for packaging bag size, thickness, and other specifications, necessitating that the insert assembly possess excellent adaptability. However, existing automated equipment often suffers from complex structures, inconvenient adjustments, and difficulty in adapting to the packaging needs of diverse products. This not only increases equipment maintenance costs but also limits its application scope. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a pin device assembly, comprising: a guide support rod; a horizontal sealing mechanism disposed on the guide support rod, the horizontal sealing mechanism comprising a base disposed on the guide support rod and a sealing block disposed on the base, the base being slidably disposed on the guide support rod; a material guiding and venting mechanism, the material guiding and venting mechanism comprising a mounting seat disposed on the base and a clamping plate disposed on the mounting seat, a material guiding gap being formed between the two clamping plates; and a pin mechanism, the pin mechanism being symmetrically disposed on both sides of the base.

[0007] In some embodiments of this utility model, the above-mentioned insertion mechanism includes a straight insertion plate located on the side of the base near the clamping plate and a triangular insertion plate located on the side of the base away from the clamping plate. The triangular insertion plate and the straight insertion plate are pushed synchronously to abut against the bag body to be inserted through a push rod bracket.

[0008] In some embodiments of this utility model, the above-mentioned material guiding and venting mechanism further includes a flexible venting plate, which is disposed on the clamping plate.

[0009] In some embodiments of this utility model, the mounting base is provided with a key-shaped hole for adjusting the position of the clamping plate, and the mounting base is fixed to the base by screws.

[0010] In some embodiments of this utility model, the above also includes a drive mechanism, which includes a power element and a transmission assembly. The power element is used to drive the base to reciprocate on the guide support rod. The transmission assembly is connected to the power element and the base respectively, and is used to drive the two bases located on the guide support rod to move closer or further apart synchronously.

[0011] In some embodiments of this utility model, the transmission assembly includes a drive rod, a transmission block, a first connecting rod, and a second connecting rod. The drive rod is connected to a power element, the transmission block is disposed on the drive rod, one end of the first connecting rod is connected to the transmission block, the end of the first connecting rod away from the transmission block is connected to any base, one end of the second connecting rod is connected to the end of the transmission block away from the first connecting rod, and the other end of the second connecting rod is connected to another base.

[0013] Beneficial effects:

[0014] This utility model provides a pin insertion device assembly, including: a guide support rod; a horizontal sealing mechanism disposed on the guide support rod, the horizontal sealing mechanism including a base supported on the guide support rod and a sealing block disposed on the base, the base being slidably disposed on the guide support rod; a material guiding and venting mechanism, the material guiding and venting mechanism including a mounting seat disposed on the base and a clamping plate disposed on the mounting seat, a material guiding gap being formed between the two clamping plates; and a pin insertion mechanism symmetrically disposed on both sides of the base. The guide support rod is used to install and fix on packaging equipment to support the horizontal sealing mechanism and the material guiding and venting mechanism. The horizontal sealing mechanism is used to horizontally seal the raw material of the pin insertion bag to be processed, and to divide the cylindrical bag into various containing spaces, thereby facilitating sealing after material filling. The base is used to install the sealing block, and the movement of the base drives the movement of the sealing block, thereby dividing the cylindrical bag raw material for continuous sealing. The aforementioned material guiding and venting mechanism guides the bag material for making the inserts and discharges excess gas from the bag after packaging by clamping it. This facilitates the removal of air from inside the bag through compression, reducing the overall bag volume, improving the utilization rate of the packaging box, and preventing the risk of bag crushing during transportation. The aforementioned insert mechanism pushes the side walls at the ends of the bag towards the central axis of the bag, and then seals it through the horizontal sealing mechanism, forming inserts at the top and bottom horizontal seals, greatly improving the stability and aesthetics of the bag.

[0015] Therefore, this insert assembly can discharge excess gas from the bag after packaging through the material guiding and venting mechanism, thereby reducing the overall volume of the bag and improving the utilization rate of the packaging box. Attached Figure Description

[0029] Example

[0030] Please refer to Figures 1-5 This embodiment provides a pin assembly, including: a guide support rod 1; a horizontal sealing mechanism disposed on the guide support rod 1, the horizontal sealing mechanism including a base 2 disposed on the guide support rod 1 and a sealing block 3 disposed on the base 2, the base 2 being slidably disposed on the guide support rod 1; a material guiding and venting mechanism, the material guiding and venting mechanism including a mounting seat 4 disposed on the base 2 and a clamping plate 5 disposed on the mounting seat 4, a material guiding gap 6 being formed between the two clamping plates 5; and a pin mechanism, the pin mechanism being symmetrically disposed on both sides of the base 2.

[0031] In this embodiment, the guide support rod 1 is used to be installed and fixed on the packaging equipment to support the horizontal sealing mechanism and the material guiding and venting mechanism.

[0032] In this embodiment, the aforementioned horizontal sealing mechanism is used to horizontally seal the raw material of the plug bag to be processed, dividing the cylindrical bag into various containing spaces, thereby facilitating sealing after material filling. Specifically, the aforementioned base 2 is used to install the sealing block 3. By driving the base 2 to move, the sealing block 3 is driven to move, thereby dividing the cylindrical bag raw material, facilitating continuous sealing. The aforementioned sealing block 3 is used to horizontally seal the cylindrical material by heat sealing, providing efficient and stable sealing of the plug bag.

[0033] In this embodiment, the aforementioned material guiding and venting mechanism is used to guide the bag material for making the bag's inserts and to discharge excess gas from the bag after packaging by clamping it. This facilitates the removal of air from inside the bag through compression, reducing the overall volume of the bag, improving the utilization rate of the packaging box, and preventing the risk of the bag breaking during transportation. Specifically, the aforementioned mounting base 4 is used to mount the aforementioned clamping plate 5 on the base 2. The aforementioned clamping plate 5 is vertically arranged on the mounting base 4, and the aforementioned clamping plate 5 and mounting base 4 are integrally formed and manufactured by processes such as stamping.

[0034] In this embodiment, the aforementioned insert mechanism is used to push the side wall at the end of the bag towards the central axis of the bag, and then seal it through the horizontal sealing mechanism, forming inserts at the upper and lower horizontal seals, which greatly improves the stability and aesthetics of the bag.

[0035] Please refer to Figure 1 and Figure 5 In some embodiments of this example, the above-mentioned insertion mechanism includes a straight insertion plate 7 located on the side of the base 2 near the clamping plate 5 and a triangular insertion plate 8 located on the side of the base 2 away from the clamping plate 5. The triangular insertion plate 8 and the straight insertion plate are pushed synchronously to abut against the bag body to be inserted through the push rod bracket 9.

[0036] In this embodiment, the installation direction of the straight foot insert 7 is parallel to the travel direction of the bag to be processed, and it is used to push the side wall of the bag towards the center of the bag to form a foot. The installation direction of the triangular insert 8 is perpendicular to the travel direction of the bag to be processed, and it lays the formed foot horizontally to improve the stability of the bag when it is placed.

[0037] Please refer to Figures 1-3 In some embodiments of this example, the above-mentioned material guiding and venting mechanism further includes a flexible venting plate 10, which is disposed on the clamping plate 5.

[0038] In this embodiment, the flexible exhaust plate 10 is installed inside the clamping plate 5. The two clamping plates 5 move closer or separate during the reciprocating motion of the base 2. When the two bases 2 move closer, the two flexible exhaust plates 10 move closer simultaneously, thereby squeezing out the excess air in the bag to be packaged. This can effectively ensure that the bag expands evenly and consistently after processing, which is convenient for packing.

[0039] Please refer to Figure 1 and Figure 2 In some embodiments of this example, the mounting base 4 is provided with a key-shaped hole 11 for adjusting the position of the clamping plate 5, and the mounting base 4 is fixed to the base 2 by screws.

[0040] In this embodiment, the key hole 11 is used to adjust the position of the mounting base 4 on the base 2, which can effectively adjust the gap between the two clamping plates 5 when they are close together. When packaging different bags, it can be adjusted accordingly to improve the adaptability of the entire pin assembly.

[0041] Please refer to Figures 1-5 In some embodiments of this example, the above also includes a drive mechanism, which includes a power element 12 and a transmission assembly. The power element 12 is used to drive the base 2 to reciprocate on the guide support rod 1. The transmission assembly is connected to the power element 12 and the base 2 respectively. The transmission assembly is used to drive the two bases 2 located on the guide support rod 1 to move closer or further apart synchronously.

[0042] In this embodiment, the driving mechanism is used to drive the base 2 to slide back and forth on the guide support rod 1. The driving mechanism can drive the two bases 2 to move closer and separate simultaneously, which facilitates venting, material guiding and sealing operations, and improves the efficiency of continuous packaging.

[0043] Please refer to Figures 1-3 In some embodiments of this example, the transmission assembly includes a drive rod 13, a transmission block 14, a first connecting rod 15, and a second connecting rod 16. The drive rod 13 is connected to the power element 12, the transmission block 14 is disposed on the drive rod 13, one end of the first connecting rod 15 is connected to the transmission block 14, the end of the first connecting rod 15 away from the transmission block 14 is connected to any base 2, one end of the second connecting rod 16 is connected to the end of the transmission block 14 away from the first connecting rod 15, and the other end of the second connecting rod 16 is connected to another base 2.

[0044] In this embodiment, the drive rod 13 is used to acquire the kinetic energy output by the drive element, and the drive rod 13 is used to rotate under the action of the drive element. The drive element is used to drive the drive rod 13 to reciprocate at a fixed angle. The transmission block 14 is used to transmit the kinetic energy acquired by the drive rod 13 to the first connecting rod 15 and the second connecting rod 16. The transmission block 14 is used to simultaneously drive the first connecting rod 15 and the second connecting rod 16. By simultaneously driving the two bases 2 acting on the first connecting rod 15 and the second connecting rod 16 through a single power source, the two bases 2 are brought closer together or separated synchronously, thereby achieving the sealing of the bag to be processed.

[0045] Please refer to Figures 3-5 In some embodiments of this example, one of the sealing blocks 3 is provided with a cutter 17, and the other sealing block 3 is provided with a cutting groove 18, into which the cutter 17 can extend.

[0046] In this embodiment, the cutter 17 is used to cut the sealed bag. When the straight foot plate 7 and the triangular plate 8 work synchronously, they act on the bottom of the next bag and the top of the previous bag, respectively. The cutter 17 can separate the connecting parts of the two bags.

[0047] In use, the bag material to be made into feet passes through the material guide gap 6 of the material guide and exhaust mechanism. The horizontal sealing mechanism is used to seal the bottom of the bag. At the same time as sealing the bottom of the bag, the packaged items are added into the bag. Then the bag with the packaged items is moved to the base 2. The top is sealed by the horizontal sealing mechanism, and the foot structure is formed at the same time. The sealing mechanism separates the finished package at the bottom from the bag material by the cutter 17.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
