Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a quick-cut film roll mechanism and its packaging machine. Background Technology

[0002] In modern packaging production, packaging machines are widely used in industries such as food, pharmaceuticals, and daily chemicals for the rapid and efficient film packaging of products.

[0003] Among them, the film roll mechanism is one of the core components of the packaging machine, responsible for providing continuous packaging film for packaging. However, the film roll mechanism of traditional packaging machines usually adopts a single roll design. When a roll of packaging film is used up, the machine needs to be stopped for manual replacement. This not only leads to a reduction in production efficiency, but may also affect the continuity and stability of the production line. Especially in high-speed and highly automated production scenarios, frequent machine stops for roll replacement will significantly increase time and labor costs and reduce work efficiency. To this end, we propose a quick-cutting film roll mechanism and its packaging machine. Utility Model Content

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides, for example Figures 1-4 The quick-cut film roll mechanism shown includes a rotating plate 101, a film roll assembly, a rotating mechanism, and a positioning mechanism. The rotating plates 101 are symmetrically arranged, and the film roll assemblies are symmetrically arranged between the two rotating plates 101. A fixing mechanism is provided between the film roll assembly and the rotating plate 101. The rotating mechanism is located on both sides of the rotating plate 101. The positioning mechanism is used to position the rotating plate 101 after rotation. Two sets of film roll assemblies are arranged between the two rotating plates 101. When the packaging film on one of the film roll assemblies is used up, the rotating plate 101 is rotated 180° with the cooperation of the rotating mechanism and the positioning mechanism, so that the two film roll assemblies exchange positions. This allows the exchanged film roll assembly to unwind packaging film for work. Then, the empty film roll assembly is disassembled and replaced, which can reduce the downtime when the packaging film is used up, thereby increasing packaging efficiency.

[0036] The rotating mechanism includes a fixed plate 201, a support base 202, and a servo motor 203. The rotating plate 101 is rotatably connected to one side of the fixed plate 201, and the support base 202 is fixedly connected to the bottom of the two fixed plates 201. The servo motor 203 is installed on the outer wall of one of the fixed plates 201, and the output end of the servo motor 203 is connected to one side of one of the rotating plates 101. The rotating plate 101 can be rotated by the operation of the servo motor 203, so that the two sets of film roll assemblies can be interchanged.

[0037] The positioning mechanism includes a positioning rod 302 and a positioning hole 303. The outer wall of the fixed plate 201 is symmetrically provided with movable holes 301. The positioning rod 302 is movably inserted into the inner wall of the movable hole 301. A moving mechanism is provided between the two positioning rods 302. The positioning hole 303 is opened on the outer wall of the rotating plate 101. The positioning rod 302 is movably inserted into the inner wall of the positioning hole 303. When the rotating plate 101 rotates and drives the membrane roll assembly to exchange positions, the positioning rod 302 moves in the movable hole 301 and inserts into the corresponding positioning hole 303, so that the rotating plate 101 and the fixed plate 201 are fixed, thereby enabling the membrane roll assembly to work stably.

[0038] The moving mechanism includes a hydraulic cylinder 401 and a connecting plate 402. The connecting plate 402 is fixedly connected between two positioning rods 302. The hydraulic cylinder 401 is installed on the outer wall of the fixed plate 201. The output end of the hydraulic cylinder 401 is connected to the outer wall of the connecting plate 402 for transmission. Through the connection of the connecting plate 402, the two positioning rods 302 can move simultaneously. Then, the hydraulic cylinder 401 can work to make the positioning mechanism work more conveniently. The hydraulic cylinder 401 and the servo motor 203 are electrically connected to an external power supply through an external switch, which makes it easy for the operator to control the servo motor 203 and the hydraulic cylinder 401, improving the safety and convenience of operation.

[0039] Among them, a guide block 501 is fixedly connected to one end of the positioning rod 302 near the positioning hole 303. The guide block 501 is set in the shape of a frustum. By setting the guide block 501, the positioning rod 302 can be guided to be inserted into the positioning hole 303, thereby improving the stability of the positioning mechanism.

[0040] The film roll assembly includes a film roller 602 and a slot 601. A bearing 603 is sleeved at the end of the film roller 602. The slot 601 is opened on the side of the rotating plate 101. The bearing 603 is inserted into the slot 601. The packaging film is directly wound on the film roller 602. The bearing 603 is fixed in the slot 601 by a fixing mechanism, so that the film roller 602 can rotate stably, thereby unwinding the packaging film wound on the film roller 602.

[0041] The fixing mechanism includes a locking bolt 702. The outer wall of the rotating plate 101 has a threaded hole 701, and the inside of the threaded hole 701 is connected to the inside of the slot 601. The thread of the locking bolt 702 is inserted into the inner wall of the threaded hole 701. After the bearing 603 is locked in the slot 601, the locking bolt 702 is tightened in the threaded hole 701, so that the locking bolt 702 tightly abuts against the bearing 603, thereby positioning the bearing 603 in the slot 601, so that the membrane roll assembly can work stably.

[0042] The inner wall of the slot 601 is fixedly connected to a limiting block 801, and one side of the inner wall of the slot 601 is fixedly connected to a limiting strip 802. The film roll mechanism at the downward opening position of the slot 601 is used for unwinding, and the film roll mechanism at the upward opening position of the slot 601 is used for replacement after use. At the same time, the limiting block 801 and the limiting strip 802 can lock the bearing 603 entering the slot 601, thereby improving the stability of the film roll mechanism.

[0043] A packaging machine comprising a quick-cut film roll mechanism according to any one of the above.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
