Description

Technical Field

[0001] This utility model relates to the field of fully automatic packaging machine technology, and in particular to a bag feeding rack for a fully automatic packaging machine. Background Technology

[0002] In modern industrial production and logistics distribution systems, product packaging is a key link connecting manufacturing and distribution. Its efficiency and quality directly affect overall operating costs and customer satisfaction. Traditional packaging operations have long relied on manual operation, where workers need to manually complete a series of actions such as bag making, bag opening, material filling, edge folding, and bag sewing. This mode is not only labor-intensive and slow, but also has significant drawbacks. Therefore, fully automatic packaging machines have emerged and developed rapidly.

[0003] The fully automatic packaging machine directly loads the pre-printed bag rolls from the woven bag factory onto the front of the packaging machine. The drive unit automatically feeds the bags, automatically labels them, automatically cuts them, and automatically sews the bottoms. Then, it automatically sucks up the bag opening, automatically stretches the bag, automatically hangs the bag, automatically fills it, and automatically sews the opening, thus completing the automatic packaging. This reduces the manual stacking and straightening process and avoids the disadvantages of frequent bag feeding, such as high labor intensity for workers and inaccurate bag positioning. It completes the cutting, bottom sewing, automatic labeling (or coding), packaging, and sealing of woven bags in one go.

[0004] The existing fully automatic bag feeding machine mainly relies on the pulling force of the front-end bag feeding machine to drive the material roller to rotate for feeding. During the feeding process, the bag feeding is not continuous. This causes the material roller to rotate due to its own inertia when the bag feeding is paused, which can easily cause the bags to fall off and accumulate, thus causing uncertainty in the next stage of tracking. In addition, the bag feeding machine lacks protective devices, and personnel can easily be caught in the bags during inspection and operation, posing certain safety hazards. Utility Model Content

[0013] More preferably, the tensioning device further includes a baffle, which is fixedly disposed on the top side of the abutment block, and the edge of the deceleration belt abuts against the baffle when the deceleration belt abuts against the abutment block.

[0014] More preferably, it also includes a guardrail, which includes a guardrail frame and casters.

[0019] The bag feeding rack of the fully automatic packaging machine of this utility model has the following advantages over the prior art:

[0020] (1) By fixing a slow belt on the tensioning bracket and placing the slow belt over the material roller, the woven bag will rub against the slow belt when the material roller rotates, which will slow down the material roller and reduce the rotation caused by the material roller's own inertia. This will prevent the material roller from overshooting and causing the woven bag to accumulate, thus affecting the tension of the woven bag. A pressure bar is fixed at the other end of the slow belt to increase the weight of the other end of the slow belt, so that the slow belt is always close to the material roller and prevents the material roller from carrying the slow belt away during rotation.

[0021] (2) By setting a limiting frame and a tensioning device on the tensioning bracket, the deceleration belt will always be kept taut under the action of the tensioning device after the pressure bar is put into the limiting frame, preventing the pressure bar and deceleration belt from loosening when fixed. The limiting frame and tensioning device play a role in storing the pressure bar and deceleration belt, avoiding obstruction when changing the material roller; (3) By setting a movable guardrail on the outside of the base, it is prevented from being rolled into the bag during the inspection and operation of the personnel on duty, improving the safety of the equipment during operation. A limiting mechanism is set on the guardrail, and the guardrail is connected to the base through the limiting mechanism to prevent the guardrail from moving during use. Attached Figure Description

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] like Figures 1-8 As shown, the bag feeding rack of the fully automatic packaging machine of this utility model includes a base 1, a material roller 2, a tensioning bracket 3, an anti-overflow mechanism 4, a fixing mechanism 5, a guardrail 6, and a roller support mechanism 7.

[0034] The base 1 provides support for the whole structure.

[0035] The material roller 2 is used to supply bags to the fully automatic packaging machine. The material roller 2 is rotatably mounted on the base 1. By rotating, the woven bags on the material roller 2 are disengaged from the material roller 2, thereby completing the feeding process.

[0036] The roller support mechanism 7 is used to support the material roller 2. The roller support mechanism 7 includes a bracket 71 and a rotating shaft 72. The bracket 71 is fixedly mounted on the base 1. The middle position of the material roller 2 is a hollow structure. The rotating shaft 72 is inserted into the material roller 2, and both ends of the rotating shaft 72 extend out of the material roller 2 and are rotatably connected to the bracket 71, which realizes the rotation of the material roller 2 and facilitates the disassembly and replacement of the material roller 2.

[0037] The tensioning bracket 3 provides tension for the conveyed woven bags. The tensioning bracket 3 is fixedly mounted on the base 1. Multiple tensioning rollers are installed inside the tensioning bracket 3. The woven bags on the material roller 2 pass through these tensioning rollers in sequence. Under the action of the tensioning rollers, the woven bags are kept taut. By controlling the tension, the entire bag feeding and subsequent process flow are ensured to operate stably, accurately, efficiently, and with high quality.

[0038] The anti-overshoot mechanism 4 is used to stabilize the rotation of the material roller 2. The anti-overshoot mechanism 4 includes a deceleration belt 41 and a pressure bar 42. One end of the deceleration belt 41 is fixedly mounted on the tensioning bracket 3 to prevent the deceleration belt 41 from falling off. The deceleration belt 41 rests on the material roller 2. When the material roller 2 rotates, the woven bag will rub against the deceleration belt 41, which will slow down the material roller 2 and reduce the rotation caused by the material roller 2's own inertia. This prevents the material roller 2 from overshooting and causing the woven bag to accumulate, thereby affecting the tension of the woven bag. The pressure bar 42 is fixedly mounted on the other end of the deceleration belt 41 to increase the weight of the other end of the deceleration belt 41, so that the deceleration belt 41 is always close to the material roller 2, preventing the material roller 2 from carrying the deceleration belt 41 away during rotation.

[0039] The fixing mechanism 5 is used to temporarily fix the deceleration belt 41 and the pressure bar 42 when replacing the material roller 2. The fixing mechanism 5 includes a limiting frame 51, which is fixedly installed on the top side of the tensioning bracket 3. The limiting frame 51 includes a base plate 511 and a limiting plate 512. The base plate 511 is fixedly installed on one end of the top side of the tensioning bracket 3. The limiting plate 512 is fixedly installed on the top side of the base plate 511 and is inclined so that the limiting plate 512 and the base plate 511 form an angle. The pressure bar 42 is engaged in the angle between the base plate 511 and the limiting plate 512, which limits the pressure bar 42 and prevents it from falling off.

[0040] To avoid obstruction by the deceleration belt 41 when fixing the pressure bar 42, as shown in Figure (), a groove 501 is provided on the limiting plate 512. The deceleration belt 41 can be inserted into the groove 501, which changes the force direction of the pressure bar 42 and prevents the pressure bar 42 from falling off when it is fixed.

[0041] To secure the deceleration belt 41, the fixing mechanism 5 also includes a tensioning device 52. The tensioning device 52 includes a fixing plate 521, a support 522, a guide rod 523, a stop block 524, a spring 525, and a fixing nut 526. The fixing plate 521 is fixedly mounted on the other end of the top side of the tensioning bracket 3, extending the distance between the tensioning device 52 and the limiting frame 51 to ensure the effective fixation of the deceleration belt 41. The support 522 is fixedly mounted on the top side of the fixing plate 521, providing support and guidance for the guide rod 523. The guide rod 523 is slidably mounted on the support 522. The stop block 524 is fixedly mounted on one end of the guide rod 523, and its bottom side abuts against the fixing plate 521, limiting the movement of the stop block 524 and preventing it from rotating during sliding. The deceleration belt 41... When fixing the deceleration belt 41, it abuts against the abutment 524. The deceleration belt 41 first passes over the abutment 524 and then inserts into the receiving groove 501. The spring 525 is sleeved on the guide rod 523, and the two ends of the spring 525 abut against the support 522 and the abutment 524 respectively. The spring 525 provides elastic support to the abutment 524. The abutment 524 is used to press the deceleration belt 41 to keep the deceleration belt 41 taut and prevent the deceleration belt 41 from loosening during fixing. The fixing nut 526 is connected to the other end of the guide rod 523 by threaded engagement. The fixing nut 526 abuts against the support 522. The fixing nut 526 limits the guide rod 523 to prevent it from falling off. At the same time, it can adjust the extension length of the guide rod 523, thereby adjusting the tension of the deceleration belt 41 and facilitating the fixing operation.

[0042] To prevent the deceleration belt 41 from slipping and falling off during fixing, the tensioning device 52 also includes a baffle 527. The baffle 527 is fixedly installed on the top side of the abutment block 524, and when the deceleration belt 41 abuts against the abutment block 524, its edge abuts against the baffle 527. The two ends of the deceleration belt 41 are blocked by the baffle 527 and the fixing plate 521 respectively, preventing the deceleration belt 41 from loosening.

[0043] The guardrail 6 is used to improve the safety of the equipment during operation. The guardrail 6 includes a guardrail 61 and casters 62. The guardrail 61 surrounds the outside of the base 1 and the height of the guardrail 61 is higher than the height of the material roller 2 to prevent personnel from being caught in the bag during inspection and operation. The casters 62 are fixedly installed on the bottom side of the guardrail 61 and can be used to move the guardrail 6, improving the flexibility of the device and avoiding obstruction when changing the material roller 2.

[0044] To prevent the guardrail 6 from moving during use, the guardrail 6 also includes a limiting mechanism 63. The limiting mechanism 63 includes a post 631, a slide block 632, and limiting rods 633. The post 631 is fixedly mounted on the guardrail frame 61; the slide block 632 is slidably mounted on the post 631, and to ensure the stability of the slide block 632 during sliding, the slide block 632 is connected to at least two posts 631; the limiting rods 633 are fixedly mounted on the bottom side of the slide block 632, and four limiting rods 633 are provided on the bottom side of the slide block 632. The slide 633 is symmetrically arranged about the center line of the slide 632, and the base 1 is a rectangular frame structure. Two limiting rods 633 abut against the two adjacent inner sides of the base 1, and the other two limiting rods 633 abut against the two adjacent outer sides of the base 1. After the slide 632 slides downward, it clamps the base 1 through the four limiting rods 633 at the bottom, so that the guardrail 6 is connected to the base 1 and prevents the guardrail 6 from moving. After the slide 632 slides upward, the four limiting rods 633 disengage from the base 1, and the guardrail 6 can move freely.

[0045] In order to further improve the stability of the guardrail 6 when it is fixed, as shown in Figure (1), there are two limiting mechanisms 63 on the guardrail 61, and the two limiting mechanisms 63 are symmetrically arranged about the center line of the guardrail 61, so that both ends of the guardrail 6 can be fixed.

[0046] The method of using the bag feeding rack of the fully automatic packaging machine of this utility model is as follows:

[0047] First, the worker uses a forklift to lift the material roller 2, inserts it into the rotating shaft 72, pushes the material roller 2 into the bracket 71, and installs the rotating shaft 72 onto the bracket 71. The worker then locates the starting end of the woven bag on the material roller 2, passes the woven bag sequentially through the tension roller on the tension bracket 3, and feeds it into the fully automatic baling machine. The worker then places the deceleration belt 41 onto the material roller 2 and allows the pressure bar 42 to hang freely. The fully automatic baling machine pulls the woven bag to feed it. After feeding is complete, the worker pushes the protective railing 6 to the outside of the base 1 and downwards. The sliding block 632 causes the limiting rod 633 to lock the base 1, preventing the guardrail 6 from moving. When the material roller 2 needs to be replaced, slide the sliding block 632 upward to disengage the limiting rod 633 from the base 1. After removing the guardrail 6, lift the pressure bar 42, and after the deceleration belt 41 passes over the stop block 524, put the pressure bar 42 into the limiting frame 51 and insert the deceleration belt 41 into the receiving groove 501. At this time, the deceleration belt 41 is kept taut under the pressure of the stop block 524, and the material roller 2 can be replaced.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
