Description

Technical Field

[0001] The invention relates to the field of packaging equipment, and in particular to a packaging machine head and a packaging method. Background Art

[0002] The baler wraps the goods by controlling the directional movement of the strapping tape, thereby improving the stability of the goods during storage and transportation and improving the efficiency of cargo transportation. The packaging principle of the baler is roughly the same, the strapping tape is looped and buckled, and the overlapping parts are melted and cut off to achieve a one-time packaging process.

[0003] Traditional balers are internally provided with pneumatic and electric clamping control elements, wherein the control elements are used to clamp and limit the ends of the strapping tape and to melt and cut them off; however, the working torque of the starting or electric clamping control elements is limited, and coordination with the central control element is required, resulting in poor overall clamping effect, high failure rate, and limited packaging efficiency; some companies use mechanical control to achieve automatic clamping and limiting of strapping tape, such as the patent document: A strapping baler (CN112027238A), in which the corresponding pressure knife is controlled by a cam to move, thereby achieving clamping and limiting of the strapping tape in turn, and completing a packaging operation quickly and orderly.

[0004] The solutions including the above-mentioned solution all have a common problem. In the traditional solution, a pre-tightening force is applied to the pressure knife through a spring. After the cam is staggered, the spring works to achieve the clamping limit of the strapping tape. The effect of the force applied by the spring is limited. During the long-term operation of the spring, the pre-tightening force applied by the spring changes, the clamping effect of the strapping tape becomes worse, the strapping tape slips, and the strapping tape cannot be buckled. Secondly, the spring is used to apply the pre-tightening force, but its clamping effect is limited and cannot be adjusted according to the thickness of the strapping tape. For the packaging of precision equipment, the final packaging effect is flawed and does not meet the packaging requirements. Summary of the invention

[0045] Please refer to the attached Figure 2 And attached Figure 4; A counting detection assembly 100 located on one side of the built-in belt guide assembly 300 is installed on the side wall of the mounting frame, and the counting detection assembly 100 includes a detection mounting frame 110, and a counting detection wheel 120 located on the moving path of the strapping belt is installed on the side wall of the detection mounting frame 110, wherein the strapping belt can drive the counting detection wheel 120 to rotate synchronously under the action of friction during the movement process to realize the drive control process, and the counting detection wheel 120 is set to detect the running state of the strapping belt, so as to detect the moving state of the strapping belt and the moving time, and the above information is transmitted to the central processing unit to control the motor and the clutch to realize the overall control; the pump air is fixedly connected to the detection cylinder 130 through the detection shaft on the counting detection wheel 120, and the side wall of the detection cylinder 130 is installed with a pump air pipeline 140, and the pump air pipeline 140 is consistent with the axis of the detection shaft, and an eccentric control block is sealed and slidably connected in the detection cylinder 130, and an air jet nozzle is fixedly connected to the inner wall of the built-in belt guide assembly 300, and the end of the pump air pipeline 140 is connected to the air jet nozzle The counting detection wheel 120 controls the movement of the eccentric control block during the rotation process to make the pump air pipeline 140 conductive and finally make the air jet nozzle spray gas; the arrangement position of the air jet nozzle is set according to actual requirements. Taking the attached figure as an example, the inner bottom and inner side wall of the built-in belt guide component 300 close to the clamping and cutting device 500 can be set, and the blown gas can provide force to the strapping belt, reduce its contact with the inner wall of the built-in belt guide component 300, reduce friction, make the strapping belt move more smoothly, and reduce the overall friction loss; in addition, the gas blown out from the side wall can clean the upper end surface of the strapping belt. Some debris will be generated during the movement and tensioning of the strapping belt, which needs to be cleaned manually with an air gun regularly. By setting the air jet nozzle, the friction loss can be reduced on the one hand, and the debris on the surface of the strapping belt can be cleaned on the other hand, so as to improve the overall cleanliness of the strapping belt, improve the packaging effect, reduce the workload of the staff, and ensure that the overall equipment can operate stably for a long time.

The first section of the pipeline is connected to an external pump air source. During the high-speed rotation of the counting and detection wheel 120, the eccentric control block in the detection cylinder 130 is rapidly deflected by a predetermined distance under the action of centrifugal force. At this time, the eccentric control block acts as a valve, which can make the first section of the pipeline and the second section of the pipeline conduct and be in a connected state, thereby realizing gas conduction control at the moment when the strapping belt moves; the eccentric control block is in the rated position under the action of the elastic element, at which time the gas path is cut off and the whole is stable; and a position control detection element, such as an electric control detection element, can be installed on the surface of the eccentric control block. After the movement, the electric control detection elements are in contact. At this time, it is used to judge whether the strapping belt has moved and the moving distance, thereby realizing the detection of the strapping belt state. The electric control detection element can also be selected as two sets of conductive sheets. After the movement, the corresponding circuit is in a conducting state to realize the detection function.
