Description of the new model: [Technical field to which the new model belongs] This creation belongs to a packaged object in a charter machine '. The tightening force to tighten the belt is 2 ~, especially the heart-type is installed in the unacceptable adjustment mechanism. [Such technology] The strapping machine is a common type of sealing—λ The tightening force required to load the object is not π & private equipment, because the tightening force is different due to different packages, so there is the same as the first Four to eight tension adjustment devices •, # ι / 〇), the drive motor (60) of the strapping machine through a drive cam (61) 7〇) ^ sjl ~, the tension adjustment device (70) includes A tension arm (7i) capable of following the driving cam, a belt clamping device (72) provided at the top to deflect ψ ψ Ψ r 7 〇λ (71), a tension arm f7l, a lever (7 1) is provided coaxially at the bottom, and an eccentricity adjustment machine Μ f η λ \ Yes-Manually controlled rotation Turn the knob (7 4 workers) to make a ", '4 1", finely make the tension adjustment cam (742 "turn two, and then adjust the tightening force of the belt, as shown in the fifth figure Shown is the shape of a tie. ¾ ', and the sixth figure shows the most tight state of the tie. However, the knob (7 4 " A ratchet (not shown in the figure) is engaged with each other. Therefore, when you want to adjust and rotate the knob (7 4 i), you must first pull out the knob (7 4 1) to get out of the ratchet, and then you can rotate to the desired position. Need an angle, and then loosen the knob (74 workers) to re-engage it with the ratchet. This is a very inconvenient way of operation. And when the knob (7 4 1) is rotated and re-fixed, it is very likely to cause It rotates by an angle, and M275163, which is not the original predetermined position, needs to be adjusted again, which is quite troublesome. Furthermore, the fork is limited to the mechanical structure, and it has only a few segments to adjust, so the types of adjustable tightness are limited and cannot be adjusted. Find the tightening force that is most suitable for different packages. [New content] In order to improve the above defects, the main purpose of this creation is to provide a tightening force adjustment mechanism that is easy to operate and has a variety of different tightening forces. _ For the above purpose The main technical means of this creation is to replace the original hand control with the electronic control combined with the mechanical mechanism to move the material. The specific technical content of this creation includes the driving device, and its power output terminal is provided with a A shaft, the rotating shaft and connected to the tension adjusting cam; a feedback element connected to a shaft; a synchronous fine-tuning control group, including two gears meshing with each other, the two gear trains are respectively fixed on the rotating shaft and the shaft; A tight sighing device and a controller are connected to the tightening force setting device at the signal receiving end. The controller is also connected with a feedback element and a driving device. The controller can send a signal to instruct the driving device to rotate. By the above technical means, this creation can achieve several advantages ... 1 Convenient operation ... When you want to adjust the appropriate tightening force, you only need to set the tightening force setting device, which is extremely convenient to operate. 2 It can be adjusted in multiple stages to make the packaging To obtain the most appropriate tightening force: Because this creative system uses electronically controlled tension to adjust the rotation angle of the cam, no: it is also affected by the mechanical structure. Not only is the angle accurate, but it can also be divided into many segments. All can obtain the most appropriate tightening force. 5 M275163 [Embodiment] Please refer to the first and second illustrations. Chuan ★ a is a three-dimensional exploded view of this creation. The tightening force adjustment mechanism (1 m ^ 丄, 丄) is used to drive the tension adjustment cam. (50) Rotate, and then adjust the tightness of the belt. Due to the tension adjustment cam (50) cooperates with the lever and tension arm σ. The method of weekly adjustment is the same as that of existing products, and it is not the focus of this case, so it will not be repeated here. The tightening force adjusting mechanism (1) includes a synchronous fine-tuning control of a driving device (㈠0), a feedback element (20), a feedback element (20) and a driving device (1 0) connected at the same time. Group ㈡〇), straight, the drive device (10) may be a digitally controlled DC motor or ㈣ motor, stepper motor, etc., the power output terminal of the basin is connected with a reduction mechanism (11). The driving device (10) and the reduction mechanism (11) are fixed on the machine of the strapping machine through a support base (11). The power output end of the reduction mechanism (11) is provided with a shaft ("), and the shaft 3 ) End and connected to a control pump (5 1) through which the tension adjusting cam (50) is placed, that is, when the driving device (10) is activated, the speed is reduced through The mechanism (1 1) causes the tension adjustment cam (50) to slowly rotate the feedback element (20), which is fixed on the machine table, and the feedback element (20) is connected to a protruding draw rod (21). , The feedback element (2 ') and the drive device i (lG) are connected together to the controller (please refer to the first picture in the figure), and the controller is Next, a tightening force setting device is used. The device can be a button type or a rotary red type. The planner can first divide the tension adjustment 6 M275163-The periphery of the cam (50) is divided into multiple areas (for example, divided into 20 angles) ), The position of each zone can be preset on the controller, and corresponding to the tightening force setting device, so adjust the tightening force setting device, that is, the module set by the controller can be selected, and its signal can drive The driving device (10) rotates; the synchronous fine-tuning control group (3 0) is composed of two-phase meshing gears (3 1) (32), and one of the gears (31) is fixed and placed on a # letting back element ( 2〇) on the shaft (21), the other gear (32) is fixed on the shaft (i 3), so when one of the gears (3 1) or (32) rotates, it will drive The other gear (32) or (3 1) rotates. / Please refer to the second figure and the third figure for the operation flow. When using this creation, the operator sets the tightening force on the operation panel according to the nature of the packaging: itu 〇1, 02 ··, The controller is converted into a commanded driving device (1 ◦) to rotate according to the set value, so that a driving device (1 0) made of a DC motor, an electric motor or a stepping motor is rotated according to the controller command, and Drive the gear (32) and the tension adjustment cam (50) to rotate. When the backup gear (32) rotates, it drives the other gear (3!) At the same time, and the feedback element (20) (adjustable resistance) is turned back together. The rotation of the 7L piece (20) will be fed back to the controller in a step-by-step manner with voltage changes. Based on the -M / ”scan 1 piece (20), the voltage value returned to the controller is the same as the original value. When the set value is compared, + when there is a difference between the right and the right, it will be converted into a command drive device (10), and the angle of the tension adjustment cam (50) will be adjusted to the most appropriate The binding body is bound by the tightening force. M275163 Therefore 'this creation uses electronic control combined with mechanical machinery The interlocking design can precisely control the tension adjustment cam to rotate to a preset angle, and 'through the digitally controlled driving device, this creation can adjust a large number of segments, so that the packaging can obtain the best tightening force.
