Description

Technical Field

[0001] The utility model relates to the technical field of horizontal packaging machines, in particular to a packaging bag clamping and unfolding device of a horizontal packaging machine. Background Art

[0002] The horizontal packaging machine is a device that automatically takes out, opens, fills and seals packaging bags. It includes four workstations: bag taking, bag opening, filling and sealing. The packaging bags are sequentially transferred through an intermittent linear conveying mechanism to achieve efficient packaging production.

[0003] In the prior art, many horizontal packaging machines are mainly limited to performing a simple clamping function to clamp packaging bags. However, during operation, many packaging bags need to be unfolded after clamping in order to smoothly fill the bags. Due to the lack of a stable bag unfolding and fixing mechanism, these horizontal packaging machines cannot firmly fix the packaging bags when clamping them, which may cause accidents such as displacement or damage of the packaging bags. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. Horizontal packaging machines are mostly limited to simply clamping packaging bags, but the bags need to be unfolded for smooth filling during operation. Due to the lack of stable bag unfolding and fixing mechanisms, the packaging bags are not fixed stably when clamped, which can easily lead to displacement or damage.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the packaging bag clamping and unfolding device of the horizontal packaging machine includes a fixed frame, the fixed frame is provided with two first motors, the output ends of the two first motors are respectively connected to a screw rod, the two screw rods are respectively threadedly connected to a moving block, the two moving blocks are respectively slidably connected to a guide rod, the two moving blocks are arranged at both ends of the equipment platform, the equipment platform is provided with two slide grooves, the two slide grooves are slidably connected to a slider, the two sliders are respectively provided with racks on one side close to each other, the two racks are meshed and connected to the same gear, the gear is connected to the output end of the second motor through a rotating shaft, the two sliders are provided with support rods, and the two support rods are installed with two clamping blocks through two connecting rods.

[0006] Optionally, the screw rod and the guide rod are arranged parallel to each other.

[0007] Optionally, the second motor is fixed on the equipment platform.

[0008] Optionally, the first motor is fixed on a motor mounting plate, and the motor mounting plate is arranged on a fixed frame.

[0009] Optionally, the two equipment platforms are arranged in mirror images of each other, and the two first motors and the connected screw rods are installed opposite to each other.

[0010] Optionally, the screw rod is designed as a bidirectional thread structure, so that two moving blocks on the same side can be independently threadedly connected to different thread segments of the screw rod.

[0011] Optionally, the first fixing rod and the second fixing rod are respectively connected to two sides of the fixed frame.

[0012] Optionally, the end of the screw rod away from the first motor is installed inside a bearing seat, and the bearing seat is fixed on a fixed frame.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] In the utility model, the rotating shaft starts to rotate through the drive of the second motor, and the gear on the rotating shaft is meshed and connected with the racks on both sides, so that the sliders on both sides can approach or move away from each other when the gears rotate. This design enables two adjacent clamping blocks to tightly clamp one side of the packaging bag. In addition, the equipment platform is designed as two parts, which can clamp both sides of the packaging bag at the same time to ensure that the packaging bag remains stable during operation. At the same time, the first motor drives the screw rod to rotate, and the rotation of the screw rod drives the translational movement of the moving block. Since the moving blocks are slidingly connected to the guide rod at the same time, they can perform precise translational movement approaching or moving away from each other under the drive of the first motor. This function is used for bag unfolding operation to ensure that the packaging bag is firmly clamped and unfolded before filling, thereby facilitating the subsequent filling process.
