[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 5 The embodiment of the utility model is: a belt tensioning force adjustment structure of an inkjet printer, which is used to adjust the tensioning force of the belt tensioning part of the printer, including: a base 1, a fixing mechanism arranged on the base, a tensioning adjustment mechanism, a support seat 2, a pressing mechanism arranged on the support seat and a force display device 3, wherein the force display device is a tension meter, the tension meter is arranged on the clamping side plate, and the detection end of the tension meter is in contact with the belt in the belt tensioning part to facilitate real-time detection of the belt tension value.

[0024] Specifically, the fixing mechanism includes a bearing seat 5 provided at one end of the base for supporting one end of the belt tensioning part 4 and a clamping plate assembly provided at the other end of the base for clamping the wall panel of the belt tensioning part. The bearing seat has a V-shaped notch for convenient placement of the belt tensioning part. The pressing mechanism is used to fix and press the upper surface of the belt tensioning part, wherein the pressing mechanism includes a quick clamp 6 provided on the support plate and a clamping plate 7 connected to the quick clamp. An elastic pressure head 8 is provided on the lower surface of one side of the clamping plate, and a clamping side plate 9 is provided on the other side. The clamping side plate has a cavity for clamping the wall panel. The quick clamp can drive the clamping plate to move to two states: position A (lifting) and position B (pressing). When in position B, the cavity of the clamping side plate can clamp the top of the wall panel from above. The clamping plate assembly includes a first clamping plate 10 provided on the bottom plate and a second clamping plate 11 provided on the first clamping plate. The first clamping plate and the second clamping plate are "U"-shaped structures. The two cooperate to clamp the wall panel 24 to prevent the wall panel from moving left and right and front and back.

[0025] Specifically, the wall panel of the tensioning adjustment mechanism is provided with a motor mounting hole 12, which is an elliptical hole. The tensioning adjustment mechanism is used to push one of the pulleys of the belt tensioning part to move in the motor mounting hole of the wall panel to change the center distance between the two pulleys to adjust the belt tension between the two pulleys. The tension meter is arranged on the clamping side panel, and the detection end of the tension meter contacts the belt in the belt tensioning part to detect whether the belt tension reaches the preset value.

[0026] Specifically, the tensioning adjustment mechanism includes a support platform 13 arranged on the base, a slide rail 14 arranged on the support platform, a feed screw 15 connected to the slider on the slide rail, a push plate 16 connected to the slider on the feed screw, and an adjustment handle assembly for moving the push plate along the slide rail, wherein the push plate is an "L"-shaped structure, and the adjustment handle assembly includes a cam 17 arranged on the support platform that is rotated by a rotating shaft and a lever handle 18 connected to the cam. When the quick clamp is pressed down to drive the clamping plate to move to position B (pressing position), the lever handle is pulled to make the convex surface of the cam gradually contact the push plate to push the push plate to drive the synchronous wheel on the motor. 19 moves in the direction away from the other synchronous wheel, thereby slowly tightening the belt to contact the detection end of the tension meter, pulling the lever handle to the adjustment state (that is, driving the synchronous wheel to move to the maximum position), and then adjusting the knob 20 on the feed screw to fine-tune the position of the push plate, adjusting the value of the force display device to the target value and then stopping. Furthermore, a positioning mechanism is provided on the wall panel, and the positioning mechanism is a positioning screw 21 located on the upper and lower sides of the motor mounting hole. When the synchronous wheel is adjusted to the target position (that is, when the value displayed by the force display device reaches the preset value), the synchronous wheel on the motor can be positioned by tightening the two positioning screws.

[0027] Specifically, the tensioning adjustment mechanism also includes a push plate reset assembly, which includes a pin 22 and an elastic member 23 arranged on the support platform. One end of the elastic member is connected to the pin, and the other end is connected to the push plate. Under the action of the elastic member, the push plate can be pulled back to the initial position, and then the clamping plate is driven to move to position A by the upward flipping quick clamp to adjust the next belt tensioning part, so that the belt tensioning forces on all belt tensioning parts can be made consistent.

[0028] To sum up, the belt tensioning force adjustment structure of the inkjet printer proposed by the present invention adjusts the belt tensioning force through the tensioning adjustment mechanism, and then displays the tensioning force in real time through the force display device, and adjusts the tensioning force of different tensioning parts to the same value, which can ensure the consistency of the belt tensioning force of all tensioning parts to ensure the overall performance of the printer.
