Description

Technical Field

[0001] This utility model relates to the field of cutting mechanisms, and in particular to a garbage bag cutting mechanism. Background Technology

[0002] Garbage bags are used to collect and store various types of garbage. They make it convenient for us to collect waste generated in our daily lives or work, preventing garbage from scattering and thus maintaining a clean and hygienic environment. Garbage bags make garbage disposal and recycling more convenient. By sorting and disposing of different types of garbage bags, recycling stations can easily classify and process garbage, improving recycling rates and reducing resource waste. Sealed garbage bags can effectively reduce the spread of bacteria, viruses, and other microorganisms in garbage, lowering the risk of disease transmission. Using garbage bags can significantly improve the hygiene conditions of public places and homes, preventing odors and bacterial growth from garbage and protecting people's health.

[0003] Garbage bags are usually sold in rolls, which saves storage space. When in use, you can simply tear the roll at the tear line to remove a single garbage bag for use, which is convenient and quick.

[0004] In existing garbage bag production, there are usually cutters that cut out easy-tear lines and cutters that cut the garbage bags into rolls. When the garbage bags are rolled up by the winding device, the cutters that cut out easy-tear lines will pierce the surface of the garbage bag every other bag and create dotted easy-tear lines. After the bag is rolled up to the preset size, the cutters will cut it completely to facilitate the next roll. The operation of the two types of cutters requires two sets of cutting mechanisms to work separately. The two sets of cutting mechanisms occupy more space and increase the floor area of ​​the production line. Utility Model Content

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a garbage bag cutting mechanism, which can effectively solve the technical problem that the cutting mechanism for cutting the tear line and the cutting mechanism for cutting the garbage bag are two independent sets of mechanisms.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A garbage bag cutting mechanism includes a supporting gantry frame, on which a vertically movable cutter is mounted. One end of the cutter is serrated. A reciprocating assembly is mounted on the surface of the supporting gantry frame, and a lifting assembly is mounted at the lower end of the supporting gantry frame. The reciprocating assembly includes a drive motor, a crankshaft, a connecting rod, and a slide. The drive motor and crankshaft are both mounted on the supporting gantry frame via brackets. The two ends of the connecting rod are respectively connected to the slide and the crankshaft. A linear guide rail is provided between the slide and the supporting gantry frame. The cutter is fixedly connected to the lower end of the slide. Rotation of the crankshaft can drive the slide to reciprocate up and down along the linear guide rail via the connecting rod.

[0008] The lifting assembly includes a mounting base and a lifting cylinder. The surface of the mounting base is provided with a receiving groove, and the lifting cylinder is located in the receiving groove. The support gantry is connected to the telescopic rod of the lifting cylinder.

[0009] Furthermore, a groove is provided inside the connecting rod, and the connecting rod journal of the crankshaft is disposed in the groove. When the crankshaft rotates, the connecting rod journal of the crankshaft can move horizontally within the groove.

[0010] Furthermore, the surface of the supporting gantry frame is provided with shaft support blocks, and bearings are installed inside the shaft support blocks, with both ends of the crankshaft passing through the bearings.

[0011] Furthermore, both the drive motor and the crankshaft are connected to pulleys at one end, and the two pulleys are connected by a belt for transmission.

[0012] Furthermore, a fixed blade holder is provided on the surface of the slide table, and a chuck is provided at the end of the fixed blade holder away from the slide table. The cutter is detachably mounted in the chuck by screws.

[0013] Furthermore, the surface of the slide table is provided with a fixing groove, and the fixing groove is provided with three or more sets of bolt holes. The fixing tool holder can be fixedly connected to any set of bolt holes by bolts.

[0014] Furthermore, the lower end of the supporting gantry is provided with a guide post, and the mounting base is provided with a guide hole, with the end of the guide post away from the supporting gantry inserted into the guide hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: It is equipped with a reciprocating assembly and a lifting assembly. The reciprocating assembly can drive the cutter to move up and down, and the lifting assembly can drive the supporting gantry and the cutter on the supporting gantry to rise and fall. When the garbage bag needs to be cut with an easy-tear line, the drive motor drives the crankshaft to rotate. When the crankshaft rotates, it drives the slide table to move up and down along the linear guide rail through the connecting rod. The slide table pushes the cutter. One end of the cutter is serrated. When the cutter is close to the garbage bag, the tip of the cutter pierces the surface of the garbage bag with a dotted easy-tear line. When the garbage bag needs to be cut, the lifting cylinder retracts and drives the supporting gantry to descend. As the height of the supporting gantry is reduced, the cutter can completely cut the garbage bag when it moves to the bottom. It can cut the easy-tear line and cut the garbage bag. There is no need to separate two mechanisms to work, which makes it more convenient to use and reduces the size of the garbage bag production line. Attached Figure Description
