Description

Technical Field

[0001] The utility model relates to the technical field of laser etching, in particular to a displacement spacing adjustment mechanism for a labeling machine. Background Art

[0002] The label machine for making steel nameplates with steel strips generally moves the steel strip by actively driving the winding wheel that is socketed with the steel coil, and the steel strip can be unwound by driving it to rotate. However, in actual use, in order to avoid dislocation of the steel strip and keep it horizontal, a limit mechanism is usually set at the etching position of the steel strip to ensure the horizontal position of the steel strip. Therefore, there is a problem. If the steel strip is subject to greater resistance at this position, the winding wheel will not be able to push the steel strip forward normally during the unwinding process, which will cause the steel strip to bend. Once the steel strip is bent, the manufactured steel nameplate will be unusable or the display effect will be poor. In addition, as the steel strip is unwound, the unwinding length of the steel strip will also become shorter within the same rotation stroke of the winding wheel, so it is more difficult to control the spacing. Utility Model Content

[0003] In order to solve the problem that the above-mentioned method of driving the winding wheel to convey the steel belt easily causes the steel belt to bend and the moving spacing is difficult to control, the utility model provides a labeling machine displacement spacing adjustment mechanism.

[0004] The technical solution of this utility model is as follows:

[0005] A labeling machine displacement spacing adjustment mechanism comprises a feeding mechanism arranged on a reference horizontal plate and a winding rotating wheel arranged on a reference vertical plate;

[0006] The feeding mechanism comprises a horizontally arranged support plate, a driving shaft is arranged at both ends of the support plate, the upper end of the driving shaft is flush with the upper surface of the support plate, a clamping shaft is arranged directly above the driving shaft, and there is a gap between the clamping shaft and the driving shaft, and the size of the gap is set to be interference fit with the steel belt;

[0007] The two driving shafts are driven to rotate by the same driving motor and have the same rotation direction. The driving motor is connected to a controller and the controller is capable of adjusting a single rotation stroke of the driving motor.

[0008] The winding wheel and the driving shaft rotate in the same plane, and a steel belt is sleeved on the winding wheel, and one end of the steel belt passes through between the driving shaft and the pressing shaft.

[0009] Different from the existing method of driving the steel belt to move, the movement of the steel belt is driven by the interference fit between the clamping shaft and the driving shaft and the steel belt, which makes it easy to control the movement distance of the steel belt and only requires controlling the rotation stroke of the motor. The operation is simple and can avoid bending of the steel belt.

[0010] In order to achieve a tensioning connection between the drive motor and the drive shaft, the vertical spacing of the drive motor relative to the reference cross plate can be adjusted. Since the adjustment position of the drive shaft will affect the movement of the steel belt, adjusting the drive motor can achieve tensioning without any unexpected effects.

[0011] The control mode of the above controller is that the controller is provided with a touch screen, and the touch screen can change the single rotation stroke of the drive motor. Generally, a 2.8-inch touch screen controller can be selected.

[0012] In order to avoid misalignment of the relative rotation between the drive motor and the drive shaft, the support plate is provided with guide limit wheels on both sides of the drive shaft of the drive motor close to the drive shaft. After the belt is provided, the guide limit wheels can be used to guide the belt, the output end of the drive motor and the drive shaft to have a larger contact area, thereby preventing slippage.

[0013] As a preferred solution, the lower end of the guide limiting wheel and the upper end of the driving shaft are located in the same plane, which is convenient for the belt to be wound.

[0014] The method for realizing the position adjustment of the driving motor is that the driving motor is connected to the reference horizontal plate through an adjustment frame, and the connecting hole between the adjustment frame and the reference horizontal plate is a waist-shaped hole, and the length direction of the waist-shaped hole is parallel to the central axis of the driving shaft.

[0015] The height position adjustment of the driving motor is achieved in that the driving motor is connected to the adjustment frame through a vertically arranged waist-shaped hole.

[0016] As a preferred solution, the drive motor and the support plate are located on different sides of the reference vertical plate, and the end of the drive shaft connected to the drive motor and the guide limit wheel are both arranged on the same side as the drive motor. The side-by-side arrangement enables structural parts to be repaired as needed after a problem occurs, and avoids mutual interference between structures.

[0017] In order to prevent the steel belt from warping up, a plurality of pits are arranged on the upper surface of the support plate, and detachable magnetic blocks can be arranged in the pits.

[0018] In order to be suitable for use with steel strips of different thicknesses, the vertical spacing of the pressing shaft relative to the driving shaft can be adjusted.

[0019] The beneficial effect of the utility model is that the utility model is a labeling machine displacement spacing adjustment mechanism, which is different from the existing steel belt driving method. It is the first to use the interference fit between the driving shaft and the clamping shaft and the steel belt to realize the driving of the steel belt. Since the driving motor can accurately control the rotation stroke of the driving shaft after being connected to the driving shaft, it can ensure that the feeding distance of the steel belt is a constant value under the same rotation stroke when it is in close contact with the steel belt and moves synchronously, which is convenient for adjusting the moving spacing of the steel belt, and the above-mentioned method of pulling the steel belt to move will not cause the steel belt to bend.

[0029] like Figure 1-4 The displacement spacing adjustment mechanism of a labeling machine shown in the figure comprises a feeding mechanism 4 arranged on a reference horizontal plate 1 and a winding wheel 3 arranged on a reference vertical plate 2, and the reference vertical plate 2 is vertically arranged on the upper surface of the reference horizontal plate 1. In the above structure, the moving plane of the steel strip driven by the feeding mechanism 4 is a horizontal plane, which is convenient for laser etching, and the winding wheel 3 is arranged on the reference vertical plate 2 to ensure that the steel strip is tangent to the horizontal plane after being set, so that it can be Figure 1As shown, the horizontal steel strip is unwound normally.

[0030] And in the above structure, if Figure 5 As shown, the feeding mechanism 4 includes a horizontally arranged support plate 41, and the support plate 41 can support the steel strip to prevent the steel strip from sagging, so as to ensure the correct marking of information during the etching process. In order to prevent the steel strip from warping up, a plurality of pits are arranged on the upper surface of the support plate 41, and a removable magnetic block can be arranged in the pit. The magnetic block can absorb the steel strip so that it can be close to the upper surface of the support plate 41, thereby avoiding the warping problem and ensuring to the greatest extent that the steel strip is in a horizontal state when it is above the support plate 41.

[0031] Afterwards, in order to be able to drive the steel belt to move normally, driving shafts 42 are provided at both ends of the support plate 41. It should be noted that the upper end of the driving shaft 42 is flush with the upper surface of the support plate 41. When the steel belt passes over the driving shaft 42 and reaches the position above the support plate 41, the steel belt will not bend, so it can be ensured that the steel belt always remains in a horizontal state. In order to clamp the steel belt, a clamping shaft 43 is provided directly above the driving shaft 42, and there is a gap between the clamping shaft 43 and the driving shaft 42. The size of the gap is set to be an interference fit with the steel belt. That is to say, although the steel belt can pass through the clamping shaft 43 and the driving shaft 42, it will be clamped by the above two shafts. Therefore, during the rotation of the clamping shaft 43, it can drive the steel belt to move and drive the driving shaft 42 to rotate synchronously in the opposite direction. Different from the active unwinding method of the winding wheel 3, the diameter of the clamping shaft 43 is constant, so the steel belt will move the same amount as it rotates. In addition, when the steel belt is driven in this way, the winding wheel 3 is passively rotated, so the steel belt will not be squeezed and deformed.

[0032] In the above structure, in order to ensure the synchronization of the two driving shafts 42, the two driving shafts 42 are driven to rotate by the same driving motor 5, and the rotation direction is the same. Therefore, by controlling the driving motor 5, the movement of the steel belt can be easily controlled. For this purpose, the driving motor 5 is connected to the controller 6 and the controller 6 can adjust the single rotation stroke of the driving motor 5. When in use, it is only necessary to control the rotation of the driving motor 5 through the controller 6, and then the movement of the steel belt can be controlled. In other words, the user can freely select the displacement spacing of the labeling machine according to needs.

[0033] In order to avoid the bending of the steel strip, it should be noted that the winding wheel 3 and the driving shaft 42 rotate in the same plane. Figure 1As shown, the steel belt can normally move in a tangent plane to the winding wheel 3. Then, the winding wheel 3 is sleeved with the steel belt, and one end of the steel belt passes through the driving shaft 42 and the clamping shaft 43. When the driving shaft 42 rotates, the steel belt can be driven to move.

[0034] The above structure can be used to achieve a different method from the existing method of driving the steel belt to move. The steel belt is driven to move by the interference fit between the clamping shaft 43 and the driving shaft 42 and the steel belt, which makes it easy to control the movement distance of the steel belt. Moreover, it is only necessary to control the rotation stroke of the motor through the controller 6. The operation is simple and can avoid bending of the steel belt.

[0035] In addition to the above structure, in order to achieve the tension connection between the drive motor 5 and the drive shaft 42, the vertical spacing of the drive motor 5 relative to the reference horizontal plate 1 can be adjusted. When the height of the drive motor 5 is adjusted, the belt can be tightened. The original purpose of using the above adjustable drive motor 5 is that since the adjustment position of the drive shaft 42 will affect the movement of the steel belt, adjusting the drive motor 5 can achieve tension without any unexpected impact.

[0036] And if Figure 5 As shown, the method for adjusting the position of the driving motor 5 is that the driving motor 5 is connected to the reference horizontal plate 1 through the adjusting frame 45, and the connecting hole between the adjusting frame 45 and the reference horizontal plate 1 is a waist-shaped hole, and the length direction of the waist-shaped hole is parallel to the central axis of the driving shaft 42. By changing the fixed position of the waist-shaped hole, the position can be changed in the length direction of the waist-shaped hole. Correspondingly, the method for adjusting the height position of the driving motor 5 is that the driving motor 5 is connected to the adjusting frame 45 through a vertically arranged waist-shaped hole. The height of the driving motor 5 can be changed by only adjusting the fixed position of the waist-shaped hole, and the limit range is the uppermost and lowermost positions of the waist-shaped hole.

[0037] It should be noted that in order to avoid misalignment of the relative rotation between the drive motor 5 and the drive shaft 42, the support plate 41 is provided with guide limit wheels 44 on both sides of the drive shaft of the drive motor 5 near the drive shaft 42. After the belt is provided, the guide of the guide limit wheels 44 can make the contact area between the belt and the output end of the drive motor 5 and the drive shaft 42 larger, so that the problem of slipping is not easy to occur. Under normal circumstances, if the drive motor 5 and the drive shaft 42 are only regulated by the belt, the belt is arranged in a triangle, and the contact area between the belt and the drive motor 5 and the drive shaft 42 is small, and the above problem can be solved by adding guide limit wheels 44.

[0038] In the above structure, the lower end of the guide limiting wheel 44 and the upper end of the driving shaft 42 are located in the same plane, which is convenient for the belt to be wound.

[0039] In addition to the above structure, as a preferred embodiment, the drive motor 5 and the support plate 41 are located on different sides of the reference vertical plate 2, and the end of the drive shaft 42 connected to the drive motor 5 and the guide limit wheel 44 are both arranged on the same side as the drive motor 5. The side-by-side arrangement enables the structural parts to be repaired as needed after a problem occurs, and avoids mutual interference between structures.

[0040] In order to be suitable for steel strips of different thicknesses, the vertical spacing of the pressing shaft 43 relative to the driving shaft 42 can be adjusted.

[0041] Finally, in order to facilitate manual change of the moving spacing of the steel belt, the control mode of the controller 6 is that the controller 6 is provided with a touch screen, and the touch screen can change the single rotation stroke of the driving motor 5. Generally, a 2.8-inch touch screen controller 6 can be selected, and the touch screen controller 6 is set at a position that is easy to observe, so that the user can clearly observe the set spacing.
