Description

Technical Field

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

[0002] In the modern packaging industry, the production of packaging bags is a crucial link. With the diversification of market demand, the specifications and types of packaging bags are becoming increasingly diverse, which places higher demands on packaging bag production equipment.

[0003] Cutting is a crucial step in the production of packaging bags. However, the condition of the packaging bag before cutting significantly affects the cutting quality. Many packaging bags develop wrinkles on their surface during production due to various factors. These wrinkles may be due to the inherent properties of the material itself, such as the tendency of certain plastic films to bend and deform during production, transportation, or storage; or they may be caused by mechanical forces such as stacking and dragging during transport on the production line. When cutting wrinkled packaging bags, the wrinkles lead to irregular cutting paths and uneven edges. On the one hand, this affects the appearance quality of the packaging bag and reduces its aesthetic appeal. On the other hand, inaccurate cutting can also affect the sealing performance and other usability aspects of the packaging bag. For example, in the production of packaging bags that require precise dimensions for heat sealing or sewing, inaccurate cutting dimensions can cause problems in subsequent processes, thus affecting the overall quality of the packaging bag. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-specification cutting device for packaging bag production.

[0005] This utility model is achieved using the following technical solution: a multi-specification cutting device for packaging bag production, comprising a support platform, a cutting frame fixedly connected to the upper surface of the support platform, a cylinder fixedly connected to the upper surface of the cutting frame, a piston rod fixedly connected to the output end of the cylinder, a blade holder fixedly connected to the bottom end of the piston rod, a cutting blade fixedly connected to the surface of the blade holder, adjusting frames fixedly connected to both sides of the upper surface of the support platform, a limit groove formed on the surface of the adjusting frame, a mounting block slidably connected inside the limit groove, an electric push rod fixedly connected to the upper surface of the mounting block, a mounting plate fixedly connected to the surface of the mounting block, a motor fixedly connected to the surface of the mounting plate, a driving bevel gear fixedly connected to the output end of the motor, a driven bevel gear meshing with the surface of the driving bevel gear, and a flattening roller fixedly connected inside the driven bevel gear.

[0006] The above technical solution can adapt to packaging bags of different thicknesses. By adjusting the height of the flattening roller, it can meet the flattening requirements of packaging bags of different specifications. The flattening roller first flattens the packaging bag, reducing surface wrinkles, which is beneficial for subsequent cutting, improving the accuracy of cutting and the quality of the packaged bag after cutting.

[0007] As a further improvement to the above solution, a second limiting groove is provided on the upper surface of the support platform, and a placement plate is slidably connected inside the second limiting groove.

[0008] As a further improvement to the above solution, a motor base is fixedly connected to the lower surface of the support platform, and a second motor is fixedly connected inside the motor base.

[0009] As a further improvement to the above solution, a lead screw is fixedly connected to the output end of the second motor, and a threaded sleeve is threadedly connected to the outer surface of the lead screw.

[0010] The above technical solution can push the packaging bag on the placement plate, realize the control of the position of the packaging bag, and facilitate the accurate delivery of the packaging bag into the cutting area.

[0011] As a further improvement to the above solution, a push rod is fixedly connected to the surface of the threaded sleeve, and the push rod is fixedly connected to the surface of the placement plate.

[0012] The above technical solution enables the packaging bags to be automatically pushed to the cutting area without manual pushing, which improves production efficiency and reduces the errors that may be caused by manual operation.

[0013] As a further improvement to the above solution, the surface of the lead screw is rotatably connected to a bearing seat.

[0014] As a further improvement to the above solution, the bearing seat is fixedly connected to the lower surface of the support platform.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention uses an electric push rod to move the mounting block up and down along the limiting groove. The mounting block drives the mounting plate, motor, driving bevel gear, driven bevel gear, and flattening roller to move up and down as a whole. The height of the flattening roller can be adjusted according to the thickness of the packaging bag, which can meet the flattening needs of various packaging bags. At the same time, the motor drives the driving bevel gear to rotate, which meshes with the driven bevel gear, thereby driving the flattening roller to rotate. The flattening roller flattens the packaging bag at a suitable height, which can effectively reduce wrinkles on the surface of the packaging bag. In the subsequent cutting process, it can improve the cutting quality and make the cutting edges more neat, thus avoiding the problems of inaccurate cutting and poor packaging bag quality caused by wrinkles on the surface of the packaging bag.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

A cutting frame 2 is fixedly connected to the upper surface of the support platform 1. A cylinder 3 is fixedly connected to the upper surface of the cutting frame 2. A piston rod 4 is fixedly connected to the output end of the cylinder 3. A blade holder 5 is fixedly connected to the bottom end of the piston rod 4. A cutting blade 6 is fixedly connected to the surface of the blade holder 5. Adjusting frames 7 are fixedly connected to both sides of the upper surface of the support platform 1. A limit groove 8 is formed on the surface of the adjusting frame 7. A mounting block 9 is slidably connected inside the limit groove 8. An electric push rod 10 is fixedly connected to the upper surface of the mounting block 9. A... Mounting plate 11, with motor 12 fixedly connected to its surface. A driving bevel gear 13 is fixedly connected to the output end of motor 12. A driven bevel gear 14 meshes with the surface of the driving bevel gear 13. A flattening roller 15 is fixedly connected inside the driven bevel gear 14. The cutting device pushes piston rod 4 via cylinder 3, which drives blade holder 5 and its cutting blade 6 to move up and down, thus cutting the packaging bag. Mounting block 9 is slidably connected to the limiting groove 8 on adjusting frame 7. Electric push rod 10 can raise and lower mounting block 9, thereby driving the mounting plate 11, motor 12, driving bevel gear 13, driven bevel gear 14, and flattening roller 15 to rise and fall as a whole. Motor 12 drives driving bevel gear 13 to rotate, which meshes with driven bevel gear 14, thereby driving flattening roller 15 to rotate. Before the packaging bag enters the cutting frame 2, the height of the flattening roller 15 is adjusted according to the thickness of the packaging bag by the electric push rod 10. Then, the motor 12 drives the flattening roller 15 to rotate and flatten the packaging bag to reduce wrinkles.

[0026] A second limiting groove 16 is provided on the upper surface of the support platform 1. A placement plate 17 is slidably connected inside the second limiting groove 16. The second limiting groove 16 on the upper surface of the support platform 1 provides sliding space for the placement plate 17, which is used to place the packaging bag to be cut.

[0027] A motor base 18 is fixedly connected to the lower surface of the support platform 1, and a motor 19 is fixedly connected inside the motor base 18.

[0028] The output end of motor 219 is fixedly connected to lead screw 20. The outer surface of lead screw 20 is threadedly connected to threaded sleeve 21. When lead screw 20 rotates, threaded sleeve 21 connected to its outer surface will move linearly along lead screw 20.

[0029] A push rod is fixedly connected to the surface of the threaded sleeve 21. The push rod is fixedly connected to the surface of the placement plate 17. The movement of the threaded sleeve 21 is transmitted to the placement plate 17 through the push rod. Since the threaded sleeve 21 moves along the second limiting groove 16, the push rod can push the placement plate 17 to slide along the second limiting groove 16, thereby pushing the packaging bag on the surface of the placement plate 17 toward the cutting frame 2.

[0030] The surface of the lead screw 20 is rotatably connected to the bearing seat 22.

[0031] The bearing seat 22 is fixedly connected to the lower surface of the support platform 1.

[0032] The implementation principle of a multi-specification cutting device for packaging bag production in this embodiment is as follows: First, the operator adheres the packaging bag to the surface of the placement plate 17. Then, the operator starts the second motor 19, which drives the lead screw 20 to rotate. When the lead screw 20 rotates, the threaded sleeve 21, which is threaded to its outer surface, moves linearly along the lead screw 20. The movement of the threaded sleeve 21 is transmitted to the placement plate 17 via a push rod. The push rod pushes the placement plate 17 to slide along the second limiting groove 16, thereby pushing the packaging bag on the surface of the placement plate 17 towards the cutting frame 2. Based on the thickness of the packaging bag, the electric push rod 10 is operated. The electric push rod 10 pushes the mounting block 9 up and down along the first limiting groove 8. The mounting block 9 drives the mounting plate 11 and the motor... 12. The driving bevel gear 13, driven bevel gear 14, and flattening roller 15 are raised and lowered as a whole. The flattening roller 15 is adjusted to a suitable height position to ensure that it can effectively flatten the packaging bag. The motor 12 is started, which drives the driving bevel gear 13 to rotate. The driving bevel gear 13 meshes with the driven bevel gear 14, which in turn drives the flattening roller 15 to rotate. Before the packaging bag enters the cutting frame 2, the flattening roller 15 flattens the packaging bag to reduce wrinkles on the surface of the packaging bag. Then, it enters the cutting frame 2. The cylinder 3 is started, which pushes the piston rod 4. The piston rod 4 drives the blade holder 5 and the cutting blade 6 on it to move downward to realize the cutting action of the packaging bag.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
