AI Technical Summary

Technical Problem

When the edge sealing device of the bag making machine is stopped, the bag making blanks are easily pressed and bonded to the lower hot-skin board, resulting in the generation of finished packaging bag waste.

Method used

An edge sealing device including a fixed side plate, a transverse slider, a main rotating swing arm, a slave rotating swing arm and a cylinder is designed. The transverse slider is driven by the cylinder, so that the lower hot-skinned plate moves downward when stopping to avoid the blank being bonded.

Benefits of technology

Effectively prevent the bag-making blank from being bonded to the lower hot-skinned board, reducing the scrap rate of finished packaging bags.

Abstract

The utility model relates to an edge sealing device of a bag making machine. The edge sealing device comprises a rack, an upper hot ironing plate and a lower hot ironing plate. The device is characterized by further comprising a fixed side plate, a transverse sliding block, a driving rotating swing arm, a driven rotating swing arm and an air cylinder; the fixed side plate is arranged on the rack, the middle of the main rotating swing arm is rotationally arranged at one end of the fixed side plate, the lower end of the auxiliary rotating swing arm and the main rotating swing arm are rotationally arranged at the other end of the fixed side plate, and the two ends of the transverse sliding block are rotationally connected with the upper end of the main rotating swing arm and the upper end of the auxiliary rotating swing arm respectively. One end of the cylinder is fixed on a fixed side plate on one side of the lower end of the main rotating swing arm; the other end of the cylinder is rotationally connected with the lower end of the main rotating swing arm; the lower hot ironing plate is fixed on the transverse sliding block; and the upper hot ironing plate is arranged on the rack above the lower hot ironing plate. The lower hot ironing plate has the advantage that bag making blanks cannot be bonded on the lower hot ironing plate.

Description

Technical Field

[0001] The utility model relates to an edge sealing device, in particular to an edge sealing device of a bag making machine. Background Art

[0002] At present, the edge sealing device of the bag making machine includes a frame, an upper hot ironing plate and a lower hot ironing plate; the lower hot ironing plate is fixedly arranged on the frame, and the upper hot ironing plate is arranged on the frame above the lower hot ironing plate, and the upper hot ironing plate can move vertically up and down; when the bag making machine is working, the upper hot ironing plate moves vertically up and down to perform horizontal hot pressing on the bag blank. When the machine is stopped, since the lower hot ironing plate is fixedly arranged on the frame, the bag blank is easily pressed and adhered to the lower hot ironing plate under the action of the downward pressure of the upper hot ironing plate, resulting in waste of bag blank and generation of waste packaging bags. Summary of the Invention

[0003] In view of the above shortcomings, the purpose of the present invention is to provide a bag-making machine edge sealing device that can prevent the bag-making blank from adhering to the lower hot plate.

[0004] The technical content of the utility model is a side sealing device of a bag making machine, comprising a frame, an upper hot ironing plate and a lower hot ironing plate; it is characterized in that it also includes a fixed side plate, a transverse slider, a main rotating swing arm, a slave rotating swing arm and a cylinder; the fixed side plate is arranged on the frame, the middle part of the main rotating swing arm is rotatably arranged at one end of the fixed side plate, the lower end of the slave rotating swing arm is rotatably arranged at the other end of the fixed side plate corresponding to the main rotating swing arm, the two ends of the transverse slider are respectively rotatably connected to the upper ends of the main rotating swing arm and the slave rotating swing arm; one end of the cylinder is fixed to the fixed side plate on one side of the lower end of the main rotating swing arm, and the other end of the cylinder is rotatably connected to the lower end of the main rotating swing arm; the lower hot ironing plate is fixed on the transverse slider; the upper hot ironing plate is arranged on the frame above the lower hot ironing plate.

[0005] Compared with the prior art, the utility model has the following advantages: the utility model drives the horizontal slider through the cylinder, and when the machine stops, the lower hot plate moves downward by a certain distance, so that the bag-making blanks will not stick to the lower hot plate, thereby reducing the generation of waste finished packaging bags. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0007] like Figure 1As shown, a side sealing device of a bag making machine includes a frame 1, an upper hot stamping plate 2 and a lower hot stamping plate 3; it is characterized in that it also includes a fixed side plate 4, a transverse slider 5, a main rotating swing arm 6, a slave rotating swing arm 7 and a cylinder 8; the fixed side plate 4 is arranged on the frame 1, the middle part of the main rotating swing arm 6 is rotatably arranged at one end of the fixed side plate 4, the lower end of the slave rotating swing arm 7 is rotatably arranged at the other end of the fixed side plate 4 corresponding to the main rotating swing arm 6, the two ends of the transverse slider 5 are rotatably connected to the upper ends of the main rotating swing arm 6 and the slave rotating swing arm 7 respectively; one end of the cylinder 8 is fixed to the fixed side plate 4 on one side of the lower end of the main rotating swing arm 6, and the other end of the cylinder 8 is rotatably connected to the lower end of the main rotating swing arm 6; the lower hot stamping plate 3 is fixed on the transverse slider 5; the upper hot stamping plate 2 is arranged on the frame 2 above the lower hot stamping plate 3.

[0008] The working principle of the present utility model is as follows: when the machine is in the process of making bags, the cylinder 8 extends to drive the main rotating swing arm 6, which drives the transverse slider 5 to move vertically upward through the main rotating swing arm 6 and the slave rotating swing arm 7, thereby causing the lower hot ironing plate 3 to move vertically upward, thereby making and sealing the bags; when the machine is stopped, the cylinder 8 retracts to drive the main rotating swing arm 6, which drives the transverse slider 5 to move vertically downward through the main rotating swing arm 6 and the slave rotating swing arm 7, thereby causing the lower hot ironing plate 3 to move vertically downward, thereby preventing the blanks for making bags from being hot-pressed and bonded to the lower hot ironing plate.
