DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Reference Figure 1 , Figure 2 as well as Figure 6 A bar inkjet belt elasticity control component for an inkjet printer comprises a body 1 and a bar inkjet belt body 2. The body 1 is provided with a mounting groove 3, and the mounting groove 3 is rotatably connected with two driving rods 4. The two driving rods 4 are symmetrically arranged, and rollers 5 are fixedly installed on the two driving rods 4.

[0028] It is worth noting that:

[0029] 1. Both rollers 5 are equipped with a fixing mechanism that matches the strip inkjet tape body 2. The fixing mechanism consists of a clamping groove 21, an arc groove 22, an arc plate 23, a rotating groove 24, a connecting rod 25, an L-shaped rod 26, an annular groove 27 and a torsion spring 28.

[0030] 2. The clamping groove 21 is provided on the roller 5, and the clamping groove 21 cooperates with one end of the strip-shaped inkjet tape body 2. The arc groove 22 is provided on the side wall of the clamping groove 21, and the arc plate 23 is slidably connected in the arc groove 22. First, the two ends of the strip-shaped inkjet tape body 2 are respectively inserted into the two clamping grooves 21, and then the positions of the two arc plates 23 in the two arc grooves 22 are controlled so that the two ends of the strip-shaped inkjet tape body 2 are respectively entered into the two clamping grooves 21 to fix the two ends of the strip-shaped inkjet tape body 2. The strip-shaped inkjet tape body 2 can be fixed in the two rollers 5. When the tightness of the strip-shaped inkjet tape body 2 needs to be adjusted, the rotation of the two rollers 5 can be used to achieve it. Since the surface of the roller 5 is arc-shaped and relatively smooth, it can avoid damage to the strip-shaped inkjet tape body 2 when the tightness is adjusted.

[0031] 3. The rotating groove 24 is provided on the side wall of the roller 5 away from the driving rod 4, the connecting rod 25 is rotatably connected to the rotating groove 24, the torsion spring 28 is installed between the connecting rod 25 and the rotating groove 24, the L-shaped rod 26 is fixedly installed on the side wall of the connecting rod 25, and the other end of the L-shaped rod 26 is fixedly connected to the arc plate 23, the annular groove 27 is provided on the side wall of the arc groove 22, and the annular groove 27 cooperates with the L-shaped rod 26. Through the elastic force of the torsion spring 28, the two connecting rods 25 can be respectively applied with a force to deflect toward the midpoint position of the machine body 1. At this time, the two arc plates 23 can be connected to the two ends of the strip inkjet tape body 2 in the two arc grooves 22 through the connection of the two L-shaped rods 26, respectively, so as to effectively maintain the fixing effect of the strip inkjet tape body 2 between the two rollers 5.

[0032] 4. A fixing plate 29 is fixedly installed on one end of the connecting rod 25 outside the roller 5, and an adjusting rod 30 is fixedly installed on the fixing plate 29. The adjusting rod 30, the connecting rod 25 and the roller 5 are all coaxially arranged. A circular hole 31 matching the adjusting rod 30 is provided on the side wall of the body 1. A knob 32 is fixedly installed on one end of the adjusting rod 30 outside the body 1. Through the cooperation of the knob 32 and the adjusting rod 30, the position of the arc plate 23 in the arc groove 22 can be manually adjusted. Therefore, the strip inkjet tape body 2 can be quickly disassembled and assembled on the body 1 when needed.

[0033] Reference Figure 1 , Figure 3 , Figure 4 as well as Figure 5 , an adjusting mechanism is installed on the mounting groove 3, and the adjusting mechanism cooperates with the two driving rods 4, and the adjusting mechanism is composed of a rotating rod 6, a round rod 11, a driving gear 12, a fixed gear 10, a chain 9, two sprocket wheels 8 and two connecting gears 7;

[0034] It is worth noting that:

[0035] 1. The rotating rod 6 is rotatably connected in the mounting groove 3, and the rotating rod 6 is close to the driving rod 4 on the left side. Two connecting gears 7 are respectively fixedly mounted on the rotating rod 6 and the driving rod 4 on the left side, and the two connecting gears 7 are meshed. Under the meshing action of the two connecting gears 7, when the rotating rod 6 rotates, the driving rod 4 on the left side can be driven to rotate in the opposite direction at the same time.

[0036] 2. The round rod 11 is rotatably connected to the mounting groove 3, and the round rod 11 is close to the driving rod 4 on the right side. The two sprockets 8 are respectively fixedly mounted on the rotating rod 6 and the driving rod 4 on the right side. The chain 9 is mounted between the two sprockets 8. With the cooperation of the chain 9 and the two sprockets 8, the driving rod 4 on the right side can be driven to rotate in the same direction when the rotating rod 6 rotates. Conversely, when the driving rod 4 on the right side rotates, the rotating rod 6 can also be driven to rotate at the same time. At this time, the driving rod 4 on the left side can be rotated in the opposite direction at the same time.

[0037] 3. The fixed gear 10 is fixedly mounted on the driving rod 4 on the right side, and the driving gear 12 is fixedly mounted on the round rod 11, and the driving gear 12 is meshed with the fixed gear 10. Through the cooperation of the driving gear 12 and the fixed gear 10, when the round rod 11 rotates, the driving rod 4 on the right side can be driven to rotate at the same time. Therefore, when the round rod 11 is rotated, the two driving rods 4 can rotate in opposite directions at the same time. At this time, the two rollers 5 can rotate relative to each other or rotate towards each other, so that the tightness of the bar coding tape body 2 can be adjusted. This adjustment method is relatively simple to operate, does not require the aid of tools, and the roller 5 will not cause damage to the bar coding tape body 2 when it is rolled up.

[0038] 4. A turntable 13 is fixedly installed at one end of the round rod 11 outside the body 1. The diameter and the number of teeth of the driving gear 12 are smaller than the diameter and the number of teeth of the fixed gear 10, and the tooth spacing of the driving gear 12 is equal to the tooth spacing of the fixed gear 10. The advantage of the size design here is that the transmission of the driving gear 12 to the fixed gear 10 can be decelerated, so that the rotation speed and the rotation amplitude of the drum 5 are relatively low, thereby improving the adjustment accuracy of the tightness of the bar inkjet belt body 2.

[0039] 5. A plurality of positioning slots 14 are evenly arranged on the side wall of the turntable 13, a slide slot 15 is opened on the side wall of the machine body 1, and a slide rod 16 is slidably connected to the slide slot 15, a positioning rod 17 is fixedly installed on the slide rod 16, and the positioning rod 17 cooperates with one of the positioning slots 14, and a compression spring 18 is installed between the slide slot 15 and the slide rod 16. Through the elastic force of the compression spring 18, the slide rod 16 can push the positioning rod 17 to approach the turntable 13 and realize the card connection with one of the positioning slots 14. At this time, the fixation of the turntable 13 can be ensured, so that the round rod 11 can be kept fixed, so that the stability of the bar coding belt body 2 can be ensured without adjusting the tightness.

[0040] 6. A fixing rod 19 is fixedly installed in the slide groove 15, and a through hole 20 is opened on the slide rod 16 to match the fixing rod 19. The diameter of the fixing rod 19 is smaller than the inner diameter of the compression spring 18, and the fixing rod 19 and the compression spring 18 are coaxially arranged. Through the cooperation between the fixing rod 19 and the through hole 20, the moving direction of the slide rod 16 in the slide groove 15 can be ensured, and the separation of the two can be avoided.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
