Description

Technical Field

[0001] This utility model relates to the field of fixed support technology, and in particular to a plastic bag heat cutting machine. Background Technology

[0002] Plastic bags are bags made primarily of plastic (common plastics include polypropylene, polyester, nylon, etc.). They are essential items in people's daily lives and are often used to store other items. They are widely used because of their advantages of being inexpensive, extremely lightweight, having a large capacity, and being easy to store.

[0003] For example, publication number CN217993671U discloses a plastic bag heat-cutting machine, relating to the field of plastic bag processing. It includes a main body, with support legs fixedly mounted on the lower surface of the main body, a first fixing device mounted on the upper surface of the main body, a rubber pad fixedly mounted on the upper surface of the main body, and a first support frame fixedly mounted on the upper surface of the main body. A first electric push rod is fixedly mounted on the inner side of the first support frame. This plastic bag heat-cutting machine, through the coordinated use of the first electric push rod, connecting block, first support rod, and lower pressure roller, allows the first electric push rod to be operated after the plastic bag is fixed. This causes the connecting block to move the first support rod downwards under the drive of the first electric push rod, causing the lower pressure roller to move downwards under the drive of the first support rod. This allows for tension adjustment of the plastic bag on the main body, preventing the plastic bag from shifting its heat-cutting position due to looseness during heat-cutting, thus facilitating the heat-cutting process of the plastic bag.

[0004] The aforementioned patent describes a method for adjusting the tension of plastic bags on a main body by using a first electric push rod, a connecting block, a first support rod, and a lower pressure roller. However, the problem remains that plastic bags tend to stick to the hot cutting blade when the hot cutting machine is hot-cutting them, preventing normal hot cutting and affecting the quality of plastic bag production. Therefore, a plastic bag hot cutting machine is needed that can clean the plastic adhering to the hot cutting blade. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of the shortcomings of the existing plastic bag heat cutting machine, which is that the plastic bag tends to stick to the heat cutting blade when heat cutting the plastic bag, which makes it impossible to heat cut normally and affects the production quality of the plastic bag. Therefore, a plastic bag heat cutting machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a plastic bag heat-cutting machine, comprising a base plate, a first cylinder, and a heat-cutting blade.

The side of each of the two cleaning blocks that are close to each other is slidably connected to the heat-cutting blade.

[0007] The effect achieved by the above components is that the second cylinder starts and outputs to move the fixed plate, the fixed plate moves the moving plate, the moving plate moves the horizontal plate, the horizontal plate moves the vertical plate, and the telescopic rod moves the cleaning block on the surface of the hot cutting blade.

[0008] Preferably, the arc surface of the telescopic rod is fitted with a spring, and the two ends of the spring are fixedly connected to the cleaning block and the vertical plate, respectively.

[0009] The effect achieved by the above components is that the movement of the cleaning block causes the telescopic rod and spring to retract.

[0010] Preferably, two round rods are fixedly connected to the inner side of the U-shaped frame, and the arc surfaces of the two round rods are slidably connected to the cross plate.

[0011] The effect achieved by the above components is that the horizontal plate slides on the round rod.

[0012] Preferably, T-shaped groove plates are fixedly connected to both sides of the U-shaped frame.

[0013] The effect achieved by the above components is to achieve the fixation of the T-shaped groove plate and the U-shaped frame.

[0014] Preferably, a T-shaped plate is slidably connected inside the T-shaped groove plate, and one side of the T-shaped plate is fixedly connected to the movable plate.

[0015] The effect achieved by the above components is that the moving plate moves and drives the T-shaped plate to slide within the T-shaped groove.

[0016] Preferably, a heat dissipation device is provided on one side of the U-shaped plate. The heat dissipation device includes a mounting plate, one side of which is fixedly connected to the U-shaped plate, and a motor is fixedly connected to one side of the mounting plate.

[0017] The aforementioned components achieve the effect of fixing the mounting plate and the motor.

[0018] Preferably, a fan is fixedly connected to the output end of the motor.

[0019] The effect achieved by the above components is that the motor's start-up output drives the fan to rotate.

[0020] Preferably, the motor is externally fixedly connected to a support plate.

[0021] The aforementioned components achieve the effect of fixing the motor with the support plate.

[0022] Preferably, a fixing frame is fixedly connected to one end of the support plate, and a protective plate is fixedly connected to one end of the fixing frame.

[0023] The above components achieve the following effects: they fix the support plate and the fixed frame, and fix the fixed frame and the protective plate.

[0024] In summary, the beneficial effects of this utility model are as follows:

[0025] In this invention, a fixing device allows a cleaning block to slide on the surface of the hot-cutting blade when cleaning is required, thus cleaning the plastic bags adhering to the blade. This fixing device solves the problem of plastic bags easily sticking to the hot-cutting blade in traditional plastic bag hot-cutting machines, preventing normal hot-cutting and affecting the quality of plastic bag production.

[0026] In this invention, a heat dissipation device is used to start the motor when rapid cooling of the hot cutting blade is required. The motor output drives the fan to rotate, and the fan generates cold air, which is blown onto the hot cutting blade to cool it down. This heat dissipation device solves the problem that traditional plastic bag hot cutting machines cannot quickly cool down the hot cutting blade after use. Attached Figure Description

The moving plate 205 drives the horizontal plate 208 to move. The horizontal plate 208 drives the vertical plate 209 to move, so that the telescopic rod 211 drives the cleaning blocks 213 to slide on the surface of the hot cutting knife 5 to clean the plastic strips adhering to the blade of the hot cutting knife 5. Through the fixing device 2, the problem of plastic bags easily adhering to the hot cutting knife 5 when hot cutting plastic bags is solved in traditional plastic bag hot cutting machines, which makes it impossible to hot cut normally and affects the production quality of plastic bags.

[0037] With the heat dissipation device 3, when it is necessary to quickly cool down the hot cutting blade 5, the operator first starts the motor 32.
