Description

Technical Field

[0001] This invention relates to the field of calibration and testing technology, and in particular to a calibration fixture. Background Technology

[0002] Existing carton sealing machines are generally equipped with a flaring device. The function of the flaring device is to open the carton opening into a rectangle, so that the carton feeding device can smoothly push the carton from the carton opening into the carton.

[0003] After prolonged use, the opening angles of the four corner guide plates of the flaring device are prone to deviation, causing the carton to wrinkle. Once the opening angle of the guide device deviates, it requires timely calibration and repair by a maintenance worker. Current maintenance methods require maintenance workers to manually adjust the corner guide plates based on their personal experience, resulting in high manpower costs, long calibration times, and poor adjustment accuracy, while also increasing the risk of equipment failure and production quality defects. Summary of the Invention

[0045] Reference Figures 1 to 5 As shown, this invention provides a calibration fixture for calibrating the flaring device 8 of a packaging box machine. See details below. Figure 1 As shown, the flaring device 8 includes a frame 81 and four corner guide plates 82 disposed on the frame 81. The four corner guide plates 82 are arranged in pairs opposite each other in the first horizontal direction and the first vertical direction. The corner guide plate 82 includes two vertically disposed side plates 821.

[0046] In the attached diagram, direction a indicates the first horizontal direction, and direction b indicates the vertical direction.

[0047] Specifically, each corner guide plate 82 is connected to the frame 81 through a corresponding connecting component. Each corner guide plate 82 can move relative to the frame 81 to adjust its position. After the corner guide plate 82 is adjusted to the correct position relative to the frame 81, the corner guide plate 82 is fixed by the connecting component.

[0048] Ideally, the two opposite side plates 821 of the two corner guide plates 82 arranged in pairs in the first horizontal direction are on the same horizontal plane, and the two opposite side plates 821 of the two corner guide plates 82 arranged in pairs in the vertical direction are on the same horizontal plane. That is, the side plates 821 of the four corner guide plates 82 together form a rectangular space, which can open the carton opening into a rectangle. However, after long-term use, the opening angle of the four corner guide plates 82 of the flaring device 8 is prone to deviation, which requires the calibration fixture provided in this embodiment for calibration.

[0049] The following describes the process of using this calibration fixture:

[0050] First, the flaring device 8 is removed from the packaging machine and fixed to the calibration-specific workbench 9. The corner guide plate 82 is then loosened relative to the frame 81 using the connecting components, so that the corner guide plate 82 is in a movable state relative to the frame 81. Specifically, the frame 81 can be fixed to the workbench 9 using bolts or other connecting parts.

[0051] Subsequently, the first calibration block 2 is fixed vertically onto the workbench 9 via the base 1. The two first calibration blocks 2 correspond to two vertically aligned corner guide plates 82. Specifically, the base 1 has connecting holes for screws, bolts, or other fittings to fix the base 1 to the workbench 9. After the first calibration blocks 2 are assembled, the second calibration blocks 3 are installed onto their corresponding first calibration blocks 2. Each second calibration block 3 has two opposite ends that form two first calibration slots 101 with its corresponding first calibration block 2. Specifically, the first calibration slots 101 are formed by the two opposite end faces of the first calibration block 2 and the second calibration block 3. When the first calibration block 2 is fixed onto the workbench 9, the two first calibration slots 101 located between the same first calibration block 2 and second calibration block 3 are symmetrically arranged vertically. During the installation of the second calibration block 3 onto its corresponding first calibration block 2, one of the two corner guide plates 82 corresponding to that first calibration block 2 can be placed between the first calibration block 2 and the second calibration block 3. In the two corresponding corner guide plates 82 along the vertical direction, one of the side plates 821 of the upper corner guide plate 82 is located in the upper first calibration groove 101, and one of the side plates 821 of the lower corner guide plate 82 is located in the lower first calibration groove 101.

[0052] Subsequently, the third calibration block 4 and the fourth calibration block 5 are installed, with the two sets of four fourth calibration blocks 5 respectively positioned at opposite ends of the two third calibration blocks 4. After the third calibration block 4 and the fourth calibration block 5 are assembled, each third calibration block 4 can form a second calibration groove 102 with the corresponding set of two fourth calibration blocks 5 on both opposite sides. The two third calibration blocks 4 correspond to two corner guide plates 82 that are arranged in pairs in the first horizontal direction. Then, the integrally assembled third calibration block 4 and fourth calibration block 5 are placed between and close to the corresponding two corner guide plates 82. The two second calibration grooves 102 located between the same third calibration block 4 and fourth calibration block 5 are symmetrically arranged along the first horizontal direction. Of the two corresponding corner guide plates 82 along the first horizontal direction, the other side plate 821 of the left corner guide plate 82, which does not extend into the first calibration groove 101, extends into the left second calibration groove 102, and the other side plate 821 of the right corner guide plate 82, which does not extend into the first calibration groove 101, extends into the right second calibration groove 102. That is, in the same corner guide plate 82, one side plate 821 is located in the first calibration groove 101, and the other is located in the second calibration groove 102.

[0053] The cooperation of the first calibration slot 101 and the second calibration slot 102 provides reliable calibration positioning for the corresponding corner guide plates 82, enabling the two opposite side plates 821 of the two corner guide plates 82 arranged in pairs in the first horizontal direction to be calibrated to the same horizontal plane, and simultaneously enabling the two opposite side plates 821 of the two corner guide plates 82 arranged in pairs in the vertical direction to be calibrated to the same horizontal plane. After the calibration fixture is calibrated, the four corner guide plates 82 are tightened relative to the frame 81 again through the connecting components, so that the corner guide plates 82 are fixed relative to the frame 81.

[0054] In this embodiment, the base 1 has a first hole 11, and the first calibration block 2 has a second hole 21. The first hole 11 and the second hole 21 are connected by a first connector 71. Specifically, the first hole 11 is an elongated hole that extends vertically. This arrangement allows for adjustment of the relative position between the base 1 and the first calibration block 2, enabling the first calibration block 2 to have different fixed heights on the base 1.

[0055] As an optional implementation, the first connector 71 is configured as a bolt, and the second hole 21 is configured as a threaded hole. The bolt passes through the first hole 11 and the second hole 21 and is threadedly connected, thereby achieving reliable fixation between the first calibration block 2 and the base 1.

[0056] The number of the first connector 71, the first hole 11, and the second hole 21 can be adjusted according to actual design needs, and no further restrictions are imposed here.

[0057] In this embodiment, the first calibration block 2 has a third hole 22, and the second calibration block 3 has a fourth hole 31. The third hole 22 and the fourth hole 31 are connected by the second connector 72.

[0058] As an optional implementation, the second connector 72 is configured as a bolt, and the fourth hole 31 is configured as a threaded hole. The bolt passes through the third hole 22 and the fourth hole 31 for threaded connection, thereby achieving reliable fixation between the first calibration block 2 and the second calibration block 3.

[0059] The number of the second connector 72, the third hole 22 and the fourth hole 31 can be adjusted according to actual design needs, and no further restrictions are imposed here.

[0060] Furthermore, the second calibration block 3 is also provided with an eighth hole 32 corresponding to the second hole 21. After the first connector 71 passes through the first hole 11 and the second hole 21, it is also connected to the eighth hole 32, which further ensures the reliability of the integral fixation between the first calibration block 2 and the second calibration block 3.

[0061] In this embodiment, the fourth calibration block 5 includes a first stepped portion 51 and a second stepped portion 52 arranged in a stepped shape. The second stepped portion 52 is disposed at the end of the first stepped portion 51. The first stepped portion 51 is attached to and connected to the third calibration block 4. The second stepped portion 52 and the third calibration block 4 are spaced apart and together form the second calibration groove 102. Specifically, the first stepped portion 51 has a fifth hole 511, and the third calibration block 4 has a sixth hole 41. The fifth hole 511 and the sixth hole 41 are connected by a third connector 73.

[0062] As an optional implementation, the third connector 73 is configured as a bolt, and the sixth hole 41 is configured as a threaded hole. The bolt passes through the fifth hole 511 and the sixth hole 41 for threaded connection, thereby achieving reliable fixation between the fourth calibration block 5 and the third calibration block 4.

[0063] The number of the third connector 73, the fifth hole 511 and the sixth hole 41 can be adjusted according to actual design needs, and no further restrictions are imposed here.

[0064] In this embodiment, two first abutment members 61 corresponding to the first calibration groove 101 are respectively provided at opposite ends of the third calibration block 4. The first abutment members 61 can press the side plate 821 tightly against the groove wall of the first calibration groove 101. Specifically, when the first calibration block 2 and the second calibration block 3 are installed on the flaring device 8, so that the side plate 821 enters the corresponding first calibration groove 101, by providing the first abutment members 61, the side plate 821 can be firmly pressed against the groove wall of the first calibration groove 101, avoiding slight movement of the corner guide plate 82 relative to the first calibration groove 101, further ensuring the positioning of the side plate 821, and further improving the positioning calibration effect.

[0065] Optionally, the first pushing member 61 is configured as a first screw, and the third calibration block 4 is provided with a first screw hole 43 for threaded connection with the first screw. When the first screw is screwed into the first screw hole 43, the first screw can be extended relative to the third calibration block 4 by screwing it, thereby pushing against the side plate 821. The structure is simple and easy to operate. In addition, the extension distance of the first screw relative to the third calibration block 4 can be adjusted by screwing the first screw relative to the first screw hole 43, thus adapting to side plates 821 of different thicknesses.

[0066] The second calibration block 3 has two second pushers 62 at its opposite ends, each corresponding to a second calibration slot 102. The second pushers 62 press the side plate 821 tightly against the wall of the second calibration slot 102. Specifically, when the third calibration block 4 and the fourth calibration block 5 are installed on the flaring device 8, allowing the side plate 821 to enter the corresponding second calibration slot 102, the second pushers 62 firmly press the side plate 821 against the wall of the second calibration slot 102, preventing the corner guide plate 82 from moving slightly relative to the second calibration slot 102, further ensuring the positioning of the side plate 821 and improving the positioning calibration effect.

[0067] Optionally, the second pushing member 62 is configured as a second screw, and the second calibration block 3 is provided with a second screw hole 33 for threaded connection with the second screw. When the second screw is screwed into the second screw hole 33, the second screw can be extended relative to the second calibration block 3 by screwing it, thereby pushing against the side plate 821. The structure is simple and easy to operate. In addition, the extension distance of the second screw relative to the second calibration block 3 can be adjusted by screwing the second screw relative to the second screw hole 33, thus adapting to side plates 821 of different thicknesses.

[0068] Furthermore, the base 1 is provided with a third pusher 63 corresponding to the first calibration groove 101. The third pusher 63 can press the side plate 821 tightly against the groove wall of the first calibration groove 101. When the side plate 821 is located in the first calibration groove 101, the first pusher 61 and the third pusher 63 can respectively abut against the opposite sides of the side plate 821. This arrangement can further ensure the positioning and fixation of the side plate 821 in the first calibration groove 101, and improve the positioning calibration effect.

[0069] Optionally, a seventh hole 12 is provided on the base 1, and the third pusher 63 is connected to the base 1 through the seventh hole 12. Specifically, the third pusher 63 pushes against the side plate 821 after passing through the seventh hole 12. Optionally, the third pusher 63 and the seventh hole 12 can be an interference fit, a screw fit, or other fit relationships, which are not limited here.

[0070] Furthermore, the fourth calibration block 5 is provided with a fourth pusher 64 corresponding to the second calibration groove 102. The fourth pusher 64 can press the side plate 821 tightly against the groove wall of the second calibration groove 102. When the side plate 821 is located in the second calibration groove 102, the second pusher 62 and the fourth pusher 64 can respectively abut against the opposite sides of the side plate 821. This arrangement can further ensure the positioning and fixation of the side plate 821 in the second calibration groove 102, and improve the positioning calibration effect.

[0071] Optionally, the fourth calibration block 5 is provided with a third screw hole 53, and the fourth pusher 64 is correspondingly set as a third screw. When the third screw is screwed into the third screw hole 53, it extends out of the fourth calibration block 5 through the third screw hole 53 and enters the second calibration groove 102 to push against the side plate 821.

[0072] In this embodiment, the first calibration block 2 has a first chamfer 23 at both ends opposite to the side facing the base 1. The first chamfer 23 is designed to allow space for the opening of the first calibration groove 101, preventing the side plate 821 from colliding and interfering with the opening of the first calibration groove 101. The third calibration block 4 has a second chamfer 42 at both ends opposite to the side facing the fourth calibration block 5. The second chamfer 42 is designed to allow space for the opening of the second calibration groove 102, preventing the side plate 821 from colliding and interfering with the opening of the second calibration groove 102.

[0073] In summary, the calibration fixture provided in this embodiment has a simple structure and can quickly, accurately and reliably calibrate the angle and flaring opening of the corner guide plate 82 of the flaring device 8. It can effectively solve the problems of high labor cost, long calibration time and poor adjustment accuracy of the prior art in manual calibration and adjustment.

[0074] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
