Description

Technical Field

[0001] This utility model relates to the field of packaging bag cutting technology, and in particular to a device for rapid switching of cutting sizes for multi-specification packaging bags. Background Technology

[0002] In today's commodity production and distribution sectors, packaging bags, as a key carrier ensuring convenient transportation and stable storage of goods, occupy an indispensable position in both daily life and industrial production. Among them, square packaging bags are widely used by many industries due to their regular shape, good stackability, and ease of display. However, the production of these packaging bags involves relatively complex and critical technological processes. To achieve the square shape, the corners of the packaging bag must first be precisely cut, and then the cut corners are sealed using a heat-sealing process.

[0003] Since different products have different requirements for packaging bag specifications, when frequently switching cutting sizes, the traditional cutting equipment operation method requires a lot of time to manually adjust the equipment, and often requires the replacement of specific cutting parts. This undoubtedly greatly reduces production efficiency and increases production costs, becoming a bottleneck factor restricting the efficient and high-quality production of square packaging bags. In view of this, this application proposes a multi-specification packaging bag cutting size rapid switching equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for rapid switching of cutting sizes for multi-specification packaging bags.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This multi-specification packaging bag cutting size quick-change device includes two assembly plates. Each assembly plate has two symmetrically mounted slide rails on its inner side. Each pair of corresponding slide rails is slidably connected to a moving plate. Both assembly plates share multiple reciprocating sliding mechanisms, each driving the corresponding moving plate to slide up and down reciprocally. Each moving plate has a fixed drive seat on its bottom surface. Each drive seat has two symmetrically slidably connected threaded sleeves on its bottom surface. The drive seat's bottom surface has a moving mechanism that drives the two threaded sleeves to slide towards each other. Each threaded sleeve's bottom surface is rotatably connected to a rotating plate. Each threaded sleeve has two fixedly mounted electric telescopic rods on its outer sides. One end of each electric telescopic rod is rotatably connected to the outer side of the corresponding rotating plate. Each rotating plate's bottom surface has multiple symmetrically mounted spring telescopic rods, and the bottom ends of these spring telescopic rods are all fitted with cutting blades.

[0007] Preferably, each of the reciprocating sliding mechanisms includes a crankshaft, and a plurality of connecting rods are rotatably connected to the outer side of each crankshaft. The other end of each connecting rod is rotatably connected to the top surface of a corresponding moving plate. A plurality of first motors are fixedly mounted on the outer side of one of the assembly plates, and the output shaft of each first motor is connected to the corresponding crankshaft via a coupling.

[0008] Preferably, each of the moving mechanisms includes a double-ended screw, and each double-ended screw is rotatably connected to the side wall of the drive seat. Each pair of threaded sleeves corresponding to each position are symmetrically threaded onto the double-ended screw.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through a reciprocating sliding mechanism, a moving mechanism, a threaded sleeve, an electric telescopic rod, a rotating plate, a cutting blade, and other devices, enables the moving mechanism to adjust the spacing between the threaded sleeves according to the size of the packaging bag, thereby adapting to packaging bag sizes of different widths. Furthermore, the electric telescopic rod can drive the rotating plate to rotate, thereby adjusting the rotation angle of the cutting blade to meet the cutting angle requirements of square packaging bags of different specifications, thus satisfying diverse packaging bag cutting angle requirements.

[0014] 2. This utility model uses devices such as spring telescopic rods to achieve a buffering effect during the cutting process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] This utility model provides a technical solution: such as Figure 1-5 As shown, the multi-specification packaging bag cutting size quick switching device includes two assembly plates 1. Each assembly plate 1 has pre-set mounting holes, allowing it to be fixedly mounted on the cutting device. Two slide rails 4 are symmetrically installed on the inner side of each assembly plate 1. Each pair of corresponding slide rails 4 is slidably connected to a moving plate 5. The two assembly plates 1 are equipped with multiple reciprocating sliding mechanisms. Each reciprocating sliding mechanism drives the corresponding moving plate 5 to slide up and down reciprocally. A drive seat 6 is fixedly installed on the bottom surface of each moving plate 5. The bottom surface of the moving seat 6 is symmetrically connected to two threaded sleeves 9. The bottom surface of the driving seat 6 is provided with a moving mechanism, which drives the two threaded sleeves 9 to slide towards each other. The bottom surface of each threaded sleeve 9 is rotatably connected to a rotating plate 14. Electric telescopic rods 12 are fixedly installed on both outer sides of each threaded sleeve 9. One end of each electric telescopic rod 12 is rotatably connected to the outer side of the rotating plate 14 corresponding to the position. Multiple spring telescopic rods 15 are symmetrically installed on the bottom surface of each rotating plate 14. The bottom ends of the multiple spring telescopic rods 15 corresponding to the position are all jointly installed with a cutting blade 11.

[0023] Furthermore, each reciprocating sliding mechanism includes a crankshaft 2, and multiple connecting rods 7 are rotatably connected to the outer side of each crankshaft 2. The other end of each connecting rod 7 is rotatably connected to the top surface of the corresponding moving plate 5. Multiple first motors 3 are fixedly installed on the outer side of one of the assembly plates 1. The output shaft of each first motor 3 is connected to the corresponding crankshaft 2 through a coupling, which facilitates automated reciprocating cutting of the packaging bag.

[0024] Furthermore, each moving mechanism includes a double-ended screw 8, and each double-ended screw 8 is rotatably connected to the side wall of the drive seat 6. Each pair of corresponding threaded sleeves 9 are symmetrically threaded onto the double-ended screw 8. A second motor 10 is fixedly installed on the outside of each drive seat 6. The output shaft of each second motor 10 is coaxially connected to the corresponding double-ended screw 8. The double-ended screw 8 has two threads with opposite directions, which can drive the two threaded sleeves 9 to slide towards or away from each other.

[0025] Furthermore, each threaded sleeve 9 has an L-shaped support rod 13 fixedly installed on both outer sides, and each electric telescopic rod 12 is fixedly installed on the outer side of the corresponding electric telescopic rod 12, and every two L-shaped support rods 13 are arranged diagonally.

[0026] Furthermore, each drive seat 6 is provided with a T-shaped groove, and each threaded sleeve 9 is slidably connected in the corresponding T-shaped groove, which can guide and limit the threaded sleeve 9, preventing it from rotating and allowing it to slide linearly.

[0027] Furthermore, each of the second motors 10 and the first motor 3 is a conical rotor motor, whose output shaft can be locked when power is cut off, thus facilitating the limiting of equipment installed on the output shaft.

[0028] This utility model provides a device for quickly switching between different sizes of packaging bags. The specific working principle is as follows: When it is necessary to cut the corners of the packaging bag, the second motor 10 is started according to the preset size of the packaging bag. The second motor 10 drives the double-headed screw 8 to rotate. Since the two threaded sleeves 9 are threadedly connected to the double-headed screw 8 and constrained by the T-slot, the two threaded sleeves 9 slide towards or away from each other, precisely adjusting the horizontal spacing of the two cutting blades 11 to match the width requirements of the packaging bag.

[0029] Subsequently, when cutting the corners of packaging bags of different specifications, different angles of the cutting blade 11 are required. The electric telescopic rod 12 can be activated, and the electric telescopic rod 12 can be extended or shortened according to actual needs, driving the rotating plate 14 to rotate around the rotating connection point between it and the bottom surface of the threaded sleeve 9, thereby flexibly adjusting the tilt angle of the cutting blade 11 so that the cutting blade 11 can be aligned with the corner of the bag at a suitable angle.

[0030] Once ready, the first motor 3 is started. The output shaft of the first motor 3 drives the crankshaft 2 to rotate. Through the connecting rod 7, the circular motion of the crankshaft 2 is converted into the reciprocating linear motion of the moving plate 5. The moving plate 5 drives the drive seat 6, threaded sleeve 9, rotating plate 14 and cutting blade 11 to move up and down synchronously to cut the corner of the packaging bag. During the cutting process, the spring telescopic rod 15 plays a buffering role. On the one hand, it ensures that the pressure is uniform when the cutting blade 11 contacts the corner of the bag, avoiding damage to the material at the corner of the bag due to excessive pressure. On the other hand, when encountering changes in the toughness of the material during the cutting process, it can adaptively adjust the cutting force to ensure that the cut corner edge is neat and smooth, meeting the requirements of high-quality cutting.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
