Description

Technical Field

[0001] This utility model belongs to the technical field of food preservation bag making machine, specifically referring to a food preservation bag making machine with an adjustable die-cutting structure. Background Technology

[0002] In the field of food preservation bag making machines, the traditional die-cutting device often has a relatively simple blade structure, making it difficult to flexibly adjust according to the production requirements of different specifications and needs of food preservation bags. This requires frequent blade replacements during the production process, reducing production efficiency and increasing production costs.

[0003] Meanwhile, after adopting the point-cutting process, the food preservation bags need to be rolled up, at which point the winding roller becomes a critical component. However, traditional winding rollers have a fixed position, occupy a large space when not in use, and only affect the convenience of production operations. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a food storage bag making machine with an adjustable die-cutting structure, which effectively solves the problem of not being able to quickly change the blades and adjust the corresponding winding mechanism according to the needs.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a fresh bag making machine with an adjustable die-cutting structure, including a frame, a die-cutting device and a take-up roller, wherein the die-cutting device is set at one end of the frame, and an adjustment component is provided at one end of the frame near the die-cutting device, and the take-up roller is installed on the adjustment component to realize the switching between the working position and the storage position of the take-up roller;

[0006] The die-cutting device includes a mounting plate, which is fixedly mounted on both sides of the mounting frame. A lifting cylinder is vertically fixedly mounted on the mounting plate. A horizontal top frame is fixed to the top of the lifting cylinder, and a vertical side plate is fixed to the bottom of the top frame. A horizontally arranged mounting shaft is rotatably mounted on the side plate. Multiple cutting blades with different cutting edges are arrayed on the mounting shaft. A servo motor connected to the mounting shaft is fixedly mounted on the side plate. The servo motor drives the mounting shaft and the cutting blades to rotate, rotating the required cutting blades to the lowest position.

[0007] Preferably, the adjustment assembly includes a mounting frame, which is L-shaped and fixed to the outer wall of the frame. A second servo motor is fixedly mounted on the mounting frame, and a second gear is fixed to the output end of the second servo motor. An external plate is fixed to the frame near the front end of the mounting frame, and a support frame is rotatably mounted on the external plate. A first gear that meshes with the second gear is fixed on the support frame. A drive motor is fixedly mounted at one top end of the support frame, and a take-up shaft is fixedly connected to the output end of the drive motor. The take-up roller is sleeved on the take-up shaft and fixed by fastening bolts.

[0008] Preferably, at least two different types of cutters are mounted on the mounting shaft, including but not limited to point-cutting cutters and full-cutting cutters, and the cutters are detachably mounted on the mounting shaft by screws.

[0009] Preferably, gear one and gear two have the same module, the same number of teeth, and a transmission ratio of 1:1.

[0010] Preferably, the vertical height of the take-up roller relative to the frame in the non-working stored state is higher than the vertical height of the cutter relative to the frame in the lowest working position.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. The food preservation bag making machine of this application is equipped with different cutters on the mounting shaft. According to the actual production needs, the mounting shaft can be driven by a servo motor to rotate the required cutter to the lowest working position quickly. There is no need to frequently change the cutters, which greatly improves production efficiency, reduces production costs, and has high versatility.

[0013] 2. The adjustable take-up roller design allows it to be stored on top of the frame when not in use, effectively saving space; when in use, it can be quickly rotated out, enabling adjustment of the take-up roller position, reducing manual intervention, lowering labor intensity, and improving the level of intelligence in the production process.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, the present invention proposes an adjustable die-cutting structure for making fresh food bags, including a frame 1, a die-cutting device 2 and a take-up roller 3. The die-cutting device 2 is located at one end of the frame 1, and an adjustment component 4 is provided at one end of the frame 1 near the die-cutting device 2. The take-up roller 3 is installed on the adjustment component 4 to realize the switching between the working position and the storage position of the take-up roller 3.

[0022] like Figure 3 As shown, the die-cutting device 2 includes a mounting plate 5, which is fixedly mounted on both sides of the mounting frame 1. A lifting cylinder 6 is vertically fixedly mounted on the mounting plate 5. A horizontal top frame 7 is fixedly mounted on the top of the lifting cylinder 6. A vertical side plate 8 is fixedly mounted on the bottom of the top frame 7. A horizontally arranged mounting shaft 9 is rotatably mounted on the side plate 8. Multiple cutting blades 20 with different cutting edges are arranged in an array on the mounting shaft 9. A servo motor 10 connected to the mounting shaft 9 is fixedly mounted on the side plate 8. The servo motor 10 drives the mounting shaft 9 and the cutting blades 20 to rotate, rotating the required cutting blades 20 to the lowest position. At least two different types of cutting blades 20 are mounted on the mounting shaft 9. The cutting blades 20 include, but are not limited to, point-cutting cutting blades 20 and full-cutting cutting blades 20. The cutting blades 20 are detachably mounted on the mounting shaft 9 by screws.

[0023] like Figure 1As shown, the adjustment assembly 4 includes a mounting bracket 11, which is L-shaped and fixed to the outer wall of the frame 1. A servo motor 12 is fixedly mounted on the mounting bracket 11, and a gear 13 is fixed to the output end of the servo motor 12. An external plate 14 is fixed to the front end of the frame 1 near the mounting bracket 11. A support frame 15 is rotatably mounted on the external plate 14, and a gear 16 that meshes with the gear 13 is fixed on the support frame 15. A drive motor 17 is fixedly mounted on one end of the top of the support frame 15, and a take-up shaft 18 is fixedly connected to the output end of the drive motor 17. The take-up roller 3 is sleeved on the take-up shaft 18 and fixed by fastening bolts 19. The servo motor 12 drives the gear 13 to rotate, which in turn drives the gear 16 and the support frame 15 to rotate. The support frame 15 drives the take-up roller 3 to rotate, thus adjusting the position of the take-up roller 3. The gear 16 and the gear 13 have the same module and the same number of teeth, with a transmission ratio of 1:1.

[0024] like Figure 1 , 2 As shown in Figure 4, when the take-up roller 3 is in its non-working and retracted state, its vertical height relative to the frame 1 is higher than that of the cutter 20 when it is in its lowest working position relative to the frame 1. This enables the take-up roller 3 to avoid the working space of the cutter 20 when it is not in use, and to rotate out and work in coordination with the cutter 20 when it is in use.

[0025] It also includes a control system for controlling the operation of the servo motor. The control system is electrically connected to the servo motor and is used to control the rotation angle and direction of the servo motor to achieve the switching of the cutter 20 and the position adjustment of the take-up roller 3.

[0026] In practical use, based on the specifications, style and other requirements of the food storage bags to be produced, confirm the type of cutter 20 to be used, start the servo motor 10, and set the rotation angle and direction of the mounting shaft 9 through the control system. The servo motor 10 drives the mounting shaft 9 to rotate, rotating the corresponding cutter 20 to the lowest working position, so that the cutter 20 is in a state where it can perform die-cutting work.

[0027] If the take-up roller 3 is idle, it is stored above the frame 1. When the plastic bag needs to be rolled up, the servo motor 2 12 is started by the control system. The servo motor 2 12 drives the gear 2 13 to rotate, which in turn drives the gear 1 16 and the support frame 15 to rotate. The support frame 15 drives the take-up roller 3 to rotate, turning the take-up roller 3 from above the frame 1 to a suitable working position, ensuring that the position of the take-up roller 3 matches the die-cutting device 2, and can complete the winding work smoothly.

[0028] Place the raw material for the food preservation bag to be processed at the feeding end of the bag making machine, start the bag making machine, and the raw material passes through each processing station of the bag making machine in sequence to complete the bag making, die cutting and other processes. During the die cutting process, the cutter 20 cuts the food preservation bag according to the set process requirements; after the point-cutting, the winding roller 3 winds up the food preservation bag according to the set speed and tension.

[0029] After the production task is completed, stop feeding the bag making machine. After all the raw materials have been processed, turn off the running switch of the bag making machine and store the take-up roller 3 on the top of the frame 1 for easy storage and subsequent maintenance. If it is necessary to replace the cutter 20, start the servo motor again, rotate the currently used cutter 20 to the non-working position, and replace it with another cutter 20 as required.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
