Description

Technical Field

[0001] This utility model relates to the field of food preservation film packaging technology, and in particular to a food preservation film packaging device. Background Technology

[0002] Plastic wrap is a type of plastic packaging product. When sealing plastic wrap, a cutting tool is needed to cut the plastic wrap.

[0003] A search of Chinese patent CN221367927U reveals a food preservation film packaging device, belonging to the field of packaging devices. The device includes a workbench with two fixed seats fixedly connected to one end of its top. A feeding roller is rotatably mounted between the two fixed seats. A support seat is fixedly connected to the middle of the top of the workbench, and a crossbar is fixedly mounted on the top of the support seat. A screw is rotatably mounted inside the crossbar, and a motor for driving the screw is fixedly mounted at one end of the crossbar. A connecting block is threaded onto the screw, and a knife holder is fixedly connected to one side of the connecting block. A cutter is fixedly mounted at the bottom of the knife holder.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] In the current process of cutting plastic wrap, most plastic wrap is first pressed tightly and then the cutter is driven to move and cut the plastic wrap. However, the plastic wrap material is soft, and simply pressing the plastic wrap tightly results in insufficient tension, thus the cutting effect of the plastic wrap is not ideal. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a plastic wrap packaging device. A reset spring drives the movable block, pressure plate and convex strip to move downward. The convex strip can press the plastic wrap into the strip groove, thereby tensioning the plastic wrap. Then the pressure plate presses the tensioned plastic wrap onto the worktable. Then the slider drives the cutter to move continuously to cut the plastic wrap, thereby pressing and fixing the tensioned plastic wrap, thus improving the cutting effect of the cutter on the plastic wrap.

[0007] The technical solution to achieve the purpose of this utility model is: a food preservation film packaging device, including a workbench, a fixed frame fixedly connected to the top of the workbench, a slider slidably connected to the fixed frame, and further comprising;

[0008] The cutter is fixedly connected to the bottom end of the slider;

[0009] A clamping mechanism, which is located on a fixed frame;

[0010] The clamping mechanism includes a fixed rod fixedly connected to a fixed frame, a movable rod slidably connected to the bottom end of the fixed rod, a movable block fixedly connected to the bottom end of the movable rod, the movable block slidably fitting onto the fixed frame, pressure plates fixedly connected to both sides of the movable block, an installation rod fixedly connected to the top of the movable block, a bent rod fixedly connected to the top end of the installation rod, a cylindrical rod fixedly connected to the slider, the cylindrical rod contacting the bent rod, a fixed plate fixedly connected to the fixed frame, a telescopic hydraulic rod fixedly connected to the fixed plate, and the output end of the telescopic hydraulic rod fixedly connected to the slider.

[0011] In some embodiments, a return spring is sleeved on the movable rod, and the two ends of the return spring are fixedly connected to the movable block and the fixed rod, respectively.

[0012] In some embodiments, the bottom of both pressure plates is fixedly connected with protrusions, and the top of the worktable has two strip grooves, with the two protrusions located directly above the two strip grooves respectively.

[0013] In some embodiments, the top of the workbench is provided with a blade groove, and the bottom end of the cutter extends into the blade groove.

[0014] In some embodiments, two support frames are fixedly connected to the top of the workbench, and a take-up roller is rotatably connected to both support frames. A motor is fixedly connected to one of the support frames, and the output end of the motor is fixedly connected to one end of the take-up roller.

[0015] In some embodiments, a guide rod is fixedly connected to the support frame, and the guide rod is located between the cutter and the take-up roller.

[0016] Compared with existing technologies, the significant advantages of this invention are:

[0017] This invention utilizes a pressing mechanism where a telescopic hydraulic rod drives a slider and a cutter to move horizontally. The slider's movement causes a cylindrical rod to move away from the bent rod, allowing a return spring to move the movable block, pressure plate, and protrusion downwards. The protrusion presses the plastic wrap into the groove, thus tensioning the plastic wrap. The pressure plate then presses the tensioned plastic wrap onto the worktable, and the slider drives the cutter to continuously cut the plastic wrap, thereby pressing and fixing the tensioned plastic wrap and improving the cutting effect of the cutter.

[0018] This solves the problem that existing plastic wrap materials are soft and only compress the plastic wrap, resulting in insufficient tension. Attached Figure Description

[0027] This utility model provides an improved food preservation film sealing device. The technical solution of this utility model is as follows:

[0028] like Figures 1-4As shown, a food preservation film packaging device includes a workbench 1, a fixed frame 11 fixedly connected to the top of the workbench 1, a slider 12 slidably connected to the fixed frame 11, a cutter 13 fixedly connected to the bottom end of the slider 12, and a pressing mechanism located on the fixed frame 11. The pressing mechanism includes a fixed rod 2 fixedly connected to the fixed frame 11, a movable rod 21 slidably connected to the bottom end of the fixed rod 2, a movable block 23 fixedly connected to the bottom end of the movable rod 21, the movable block 23 slidably sleeved on the fixed frame 11, pressure plates 24 fixedly connected to both sides of the movable block 23, an installation rod 26 fixedly connected to the top of the movable block 23, a bending rod 27 fixedly connected to the top end of the installation rod 26, a cylindrical rod 28 fixedly connected to the slider 12, and the cylindrical rod 28 and the bending rod 27... The rod 27 is in contact with each other. A fixed plate 14 is fixedly connected to the fixed frame 11. A telescopic hydraulic rod 15 is fixedly connected to the fixed plate 14. The output end of the telescopic hydraulic rod 15 is fixedly connected to the slider 12. A return spring 22 is sleeved on the movable rod 21. The two ends of the return spring 22 are fixedly connected to the movable block 23 and the fixed rod 2, respectively. Through the setting of the pressing mechanism, the telescopic hydraulic rod 15 drives the slider 12 and the cutter 13 to move horizontally. The movement of the slider 12 drives the cylindrical rod 28 to move, so that the cylindrical rod 28 moves away from the bent rod 27. Since the return spring 22 is in a compressed state, the return spring 22 drives the movable block 23, the pressure plate 24 and the protrusion 25 to move downward, so that the pressure plate 24 presses the plastic wrap on the worktable 1, thereby pressing and fixing the tensioned plastic wrap.

[0029] like Figure 4 As shown, in one embodiment, the bottom of each of the two pressure plates 24 is fixedly connected with a protrusion 25, and the top of the workbench 1 is provided with two strip grooves 17, with the two protrusions 25 located directly above the two strip grooves 17 respectively; by setting the protrusions 25, the protrusions 25 can press the plastic wrap into the strip grooves 17, thereby tensioning the plastic wrap.

[0030] like Figure 2 As shown, in one embodiment, a knife groove 16 is provided on the top of the workbench 1, and the bottom end of the cutter 13 extends into the knife groove 16; the knife groove 16 is provided so as not to affect the movement of the cutter 13.

[0031] like Figure 2 As shown, in one embodiment, two support frames 3 are fixedly connected to the top of the workbench 1. A take-up roller 32 is rotatably connected to both support frames 3. A motor 31 is fixedly connected to one of the support frames 3. The output end of the motor 31 is fixedly connected to one end of the take-up roller 32. By setting the take-up roller 32, the motor 31 is started to drive the take-up roller 32 to rotate, so that the take-up roller 32 can take up the plastic wrap.

[0032] like Figure 2As shown, in one embodiment, a guide rod 33 is fixedly connected to the support frame 3. The guide rod 33 is located between the cutter 13 and the take-up roller 32. The guide rod 33 guides the plastic wrap.

[0033] The specific working method is as follows: The telescopic hydraulic rod 15 is activated to drive the slider 12 and the cutter 13 to move horizontally. The movement of the cutter 13 can cut the plastic wrap. During the cutting process, the slider 12 moves, driving the cylindrical rod 28 to move away from the bending rod 27. Since the return spring 22 is in a compressed state, the return spring 22 drives the movable block 23, the pressure plate 24, and the protrusion 25 to move downward. The protrusion 25 can press the plastic wrap into the strip groove 17, thereby tensioning the plastic wrap. Then, the pressure plate 24 presses the tensioned plastic wrap onto the worktable 1. Then, the slider 12 drives the cutter 13 to move continuously to cut the plastic wrap, thereby pressing and fixing the tensioned plastic wrap, thus improving the cutting effect of the cutter 13 on the plastic wrap. The motor 31 is activated to drive the winding roller 32 to rotate, enabling the winding roller 32 to wind up the plastic wrap.
