Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette packaging equipment, and particularly relates to a device for conveniently adjusting the position of a deviation detector. Background Art

[0002] As an in-line inspection device during the cigarette packaging process, the label paper offset detector is primarily used to monitor the label paper edge in real time to ensure the correct positioning of the label during subsequent packaging. During actual production, the label paper offset detector requires frequent position adjustments due to various factors, such as changes in manufacturer and batches of label paper.

[0003] In the prior art, in order to adjust the position of the label paper offset detector, the following adjustment devices are mainly used, such as Figure 1 As shown, the device includes a movable base 1, a guide rod 2, screws and a detector base 3. The movable base 1 is fixed to the guide rod 2 by screws 7, and the trademark paper offset detector 9 is connected to the movable base 1 by deviating from the detector base 3. When using this adjustment device to adjust the position of the trademark paper offset detector, it is necessary to first adjust the movable base 1 to the estimated appropriate position, and then start the packaging machine equipment for trial production to check the adjustment. If the trademark packaging is incorrect, it is necessary to stop the machine and repeat the above operation again until the trademark packaging is normal. Because the adjustment of the movable base 1 must be carried out in the stopped state, this undoubtedly requires repeated opening and closing of the equipment, which greatly increases the equipment shutdown and debugging time, reduces production efficiency, and because of the estimated adjustment, each inspection process will produce a large amount of waste and defective products, which results in a large amount of waste of raw and auxiliary materials. In addition, the adjustment process of the existing technology requires the protective cover to be fully opened so that both hands can participate in the adjustment, which adds the process of adjusting the position of the trademark paper offset detector. Relying solely on both hands to control the position of the trademark paper offset detector seriously affects the accuracy of the adjustment of the trademark paper offset detector position.

[0004] In order to solve at least one of the above problems, the present utility model is proposed. Utility Model Content

[0005] In order to address the deficiencies of the prior art, the purpose of the present invention is to provide a device for conveniently adjusting the position of an offset detector. The device allows the operator to use one hand and quickly and accurately adjust the position of the trademark paper offset detector without stopping the machine. The adjustment process does not require the removal of dust covers and other accessories installed on the production equipment. The device also effectively avoids the waste of materials and low efficiency caused by repeated adjustments and tests.

[0006] The technical solution adopted in this utility model is:

[0007] The utility model provides a device for conveniently adjusting the position of a trademark paper deviation detector, which is used to fix and adjust the position of a trademark paper deviation detector 9. The device includes: a movable base 1, a guide rod 2, a detection base 3, a fixed base 4, an adjusting screw 5, a spring 6, a screw 7 and a fixing screw 8;

[0008] The movable base 1 is fixed to the guide rod 2 by screws 7. The fixed base 4 is arranged below the movable base 1 and fixed to the guide rod 2 by fixing screws 8. A spring 6 is arranged between the movable base 1 and the fixed base 4. The adjusting screw 5 passes through the fixed base 4 and the spring 6 and is partially screwed into the bottom of the movable base 1.

[0009] One end of the spring 6 abuts against the bottom surface of the movable base 1, and the other end abuts against the top surface of the fixed base 4; as an optimal solution, when the device for adjusting the position of the trademark paper offset detector is in operation, the spring 6 is in a compressed state, with one end abutting against the bottom surface of the movable base 1 and the other end abutting against the top surface of the fixed base 4.

[0010] The fixed base 4 can also move along the guide rod 2 and does not need to be adjusted under normal circumstances. However, when the movable base 1 is adjusted beyond the range, the position of the fixed base (6) can also be adjusted to ensure that the movable base 1 can be adjusted normally.

[0011] The trademark paper deviation detector 9 is mounted on the movable base 1 via the detection base 3. The spring 6 is preferably a compression spring.

[0012] As an optimal solution, when the spring 6 is in a non-compressed state, that is, in a non-working state, part of the thread of the adjusting screw 5 is still threadedly connected to the movable base 1 .

[0013] Preferably, the movable base 1 and the fixed base 4 are respectively provided with a first through hole 11 and a second through hole 41, and the guide rod 2 passes through the first through hole 11 and the second through hole 41 respectively;

[0014] Preferably, the guide rod 2, first through hole 11, and second through hole 41 all have square cross-sections, with each side of the guide rod 2's cross-section being slightly shorter than the corresponding sides of the first through hole 11 and second through hole 41. This structure ensures a certain gap between the first through hole 11 and the outer wall of the guide rod 2, and between the second through hole 41 and the outer wall of the guide rod 2. This ensures that both the movable base 1 and the fixed base 4 can move along the length of the guide rod 2 but cannot rotate along the outer wall of the guide rod 2. This further ensures the stability of the movable base 1 and the fixed base 4 when adjusting the label stock offset detector 9.

[0015] Preferably, the lengths of the corresponding sides of the first through hole 11 and the second through hole 41 are equal.

[0016] Preferably, one end of the screw 7 passes through the side wall of the movable base 1 in a direction perpendicular to the length of the guide rod 2 and abuts against the side wall of the guide rod 2;

[0017] Preferably, one end of the fixing screw 8 passes through the side wall of the fixing base 4 along a direction perpendicular to the length of the guide rod 2 and abuts against or passes through the side wall of the guide rod 2.

[0018] Preferably, the adjusting screw 5 and the fixed base 4 are clearance-fitted, and the adjusting screw 5 and the movable base 1 are threadedly connected.

[0019] Preferably, a shoulder 51 is further provided on the outer peripheral wall of the adjusting screw 5. The shoulder 51 is located below the fixed base 4, and the outer diameter of the shoulder 51 is larger than the inner diameter of the matching hole between the fixed base 4 and the adjusting screw 5. The shoulder 51 serves to limit the axial movement between the screw 5 and the fixed base 4.

[0020] As an optimal solution, when the spring 6 is in a fully compressed state, the shoulder 51 abuts against the lower surface of the fixed base 4 .

[0021] The present invention is not limited to adjusting the position of a trademark paper offset detector, but is also applicable to position adjustment of offset detectors for other packaging materials, such as an aluminum foil offset detector. In other words, the present invention can be used as a reference for devices that have the same working principle as the trademark paper offset detector and require frequent position adjustment.

[0022] Working principle:

[0023] When the device for adjusting the position of the trademark paper offset detector of the present invention is in working state, the spring 6 is in a compressed state. When the position of the trademark paper offset detector 9 needs to be adjusted, it is only necessary to first loosen the screw 7 and then turn the adjusting screw 5 with one hand to achieve the position adjustment of the trademark paper offset detector.

[0024] When it is necessary to adjust the label paper offset detector to move upward along the guide rod 2, first loosen the screw 7, and then twist the adjusting screw 5 in the counterclockwise direction. At this time, the adjusting screw 5 is screwed out of the fixed base 4 by a certain length, and the spring 6 is reset to a certain length. During the spring reset process, the movable base 1 is simultaneously pushed to move upward along the length direction of the guide rod 2 by a certain distance (that is, the label paper offset detector moves upward along the length direction of the guide rod 2 by a certain distance). When the label paper offset detector is adjusted to the set position, tighten the screw 7 again to make it rest against the outer peripheral wall of the guide rod 2 again, and the adjustment is completed. The distance the movable base 1 moves upward along the guide rod 2 is equal to the length of the adjusting screw 5 screwed out of the fixed base 4, and is also equal to the length of the spring 6 reset.

[0025] Similarly, when it is necessary to adjust the trademark paper offset detector to move downward along the guide rod 2, first loosen the screw 7, and then twist the adjusting screw 5 in the clockwise direction. At this time, the adjusting screw 5 is screwed into the fixed base 4 to a certain length, and the spring 6 is compressed to a certain length. During the spring compression process, the movable base 1 synchronously moves downward a certain distance along the length direction of the guide rod 2 (the synchronous trademark paper offset detector moves downward a certain distance along the length direction of the guide rod 2). When the trademark paper offset detector is adjusted to the set position, tighten the screw 7 again so that it rests against the outer wall of the guide rod 2 again to complete the adjustment; the distance that the movable base 1 moves downward along the guide rod 2 is equal to the length of the adjusting screw 5 screwed into the fixed base 4, and is also equal to the increase in the compressed length of the spring 6.

[0026] Beneficial effects of the utility model:

[0027] 1. The present invention provides a clearance fit between the adjusting screw 5 and the fixed base 4, and simultaneously provides a threaded connection between the adjusting screw 5 and the movable base 1. This allows the present invention to be applied in a variety of scenarios. That is, regardless of whether the present invention is placed horizontally or vertically, or is placed at a certain angle to the ground or the wall of a packaging machine, the label paper deviation detector can be accurately adjusted along the length of the guide rod 2 and can be adjusted into place in one go.

[0028] 2. The present invention provides a spring 6, so that when the position of the trademark paper offset detector is adjusted in both directions, the movable base 1 does not need to be pushed manually. Instead, the movable base 1 can be pushed by rotating the adjustment screw 5 and the spring 6. The present invention effectively avoids the problem of trademark paper offset detector position adjustment accuracy caused by the threaded clearance between the adjustment screw 5 and the movable base 1 by providing the spring 6.

[0029] 3. Typically, existing trademark paper deviation detectors are equipped with a protective cover. Traditionally, the protective cover must be removed before adjusting the trademark paper deviation detector. However, with the device of the present invention, only a hole is provided in the protective cover corresponding to the position of the adjusting screw 5, through which one hand can reach. This allows the position of the trademark paper deviation detector to be adjusted at any time during operation of the device.

[0030] 4. The use of the device of the utility model effectively solves the problem that the packaging material cannot be adjusted in time and accurately during the production process, reduces the probability of unqualified products, and prevents unqualified products from flowing into the next production process.

[0031] 5. The use of the device of the utility model reduces the waste of packaging materials and achieves cost reduction and efficiency improvement.

[0032] 6. The device of the utility model can be used to adjust the trademark paper offset detector online, avoiding the loss of equipment efficiency caused by frequent shutdown adjustments, greatly extending the service life of the equipment, improving production efficiency, and effectively reducing equipment maintenance costs.

[0039] The following examples further illustrate the present invention in detail, but are not intended to limit the present invention. Any modifications or improvements based on the teachings of the present invention fall within the scope of protection of the present invention. Where specific techniques or conditions are not specified in the examples, the techniques or conditions described in the literature in the field or in the product instructions shall be followed.

[0040] Example 1

[0041] like Figure 2 As shown, a device for conveniently adjusting the position of a label paper deviation detector is installed on the wall panel of a packaging machine and is used to fix and adjust the position of a label paper deviation detector 9. The device includes: a movable base 1, a guide rod 2, a detection base 3, a fixed base 4, an adjustment screw 5, a spring 6, a screw 7, and a fixing screw 8;

[0042] The movable base 1 is fixed to the guide rod 2 by screws 7. The fixed base 4 is arranged below the movable base 1 and fixed to the guide rod 2 by fixing screws 8. A spring 6 is arranged between the movable base 1 and the fixed base 4. The adjusting screw 5 passes through the fixed base 4 and the spring 6 and is partially screwed into the bottom of the movable base 1. The spring 6 is a compression spring and is in a compressed state.

[0043] One end of the spring 6 abuts against the bottom surface of the movable base 1, and the other end abuts against the top surface of the fixed base 4; as an optimal solution, when the device for adjusting the position of the trademark paper offset detector is in operation, the spring 6 is in a compressed state, with one end abutting against the bottom surface of the movable base 1 and the other end abutting against the top surface of the fixed base 4.

[0044] The trademark paper deviation detector 9 is installed on the movable base 1 through the detection base 3.

[0045] The spring 6 is in a compressed state during operation;

[0046] The movable base 1 and the fixed base 4 are respectively provided with a first through hole 11 and a second through hole 41, and the guide rod 2 passes through the first through hole 11 and the second through hole 41 respectively, with a certain gap left between the guide rod 2 and the first through hole 11 and the second through hole 41;

[0047] The guide rod 2, first through hole 11, and second through hole 41 all have square cross-sections, with each side of the guide rod 2's cross-section being slightly shorter than the corresponding sides of the first through hole 11 and second through hole 41. This structure ensures a certain gap between the first through hole 11 and the outer wall of the guide rod 2, and between the second through hole 41 and the outer wall of the guide rod 2. This ensures that both the movable base 1 and the fixed base 4 can move along the length of the guide rod 2 but cannot rotate along the outer wall of the guide rod 2. This further ensures the stability of the movable base 1 and the fixed base 4 when adjusting the label stock offset detector 9.

[0048] The lengths of the corresponding sides of the first through hole 11 and the second through hole 41 are equal.

[0049] One end of the screw 7 passes through the side wall of the movable base 1 in a direction perpendicular to the length of the guide rod 2 and abuts against the side wall of the guide rod 2;

[0050] One end of the fixing screw 8 passes through the side wall of the fixing base 4 along a direction perpendicular to the length of the guide rod 2 and abuts against or passes through the side wall of the guide rod 2.

[0051] The adjusting screw 5 and the fixed base 4 are clearance-fitted, and the adjusting screw 5 and the movable base 1 are threadedly connected.

[0052] A shoulder 51 is further provided on the outer peripheral wall of the adjusting screw 5 . The shoulder 51 is located below the fixed base 4 , and the outer diameter of the shoulder 51 is larger than the inner diameter of the matching hole between the fixed base 4 and the adjusting screw 5 .

[0053] During operation of the packaging machine, the label paper 10 passes through the accommodation space formed by the label paper deviation detector 9 and the movable base. The label paper deviation detector 9 utilizes the principle of photoelectric detection to monitor the edge position of the label paper 10 in real time. When the label paper 10 runs off the edge, that is, when the edge of the label paper 10 deviates from the monitoring reference position of the label paper deviation detector 9, the label paper deviation detector 9 detects the specific position of the edge of the label paper 10 deviating from the monitoring reference position and transmits this signal to the control system. The control system, based on this signal, controls the label paper deviation correction device to correct the label paper conveying position. When the edge of the label paper 10 returns to the monitoring reference position of the label paper deviation detector 9, the correction is complete. However, if the label paper batch changes or joints mentioned in the background technology cause the actual packaging position of the label paper to be different from the required position, the monitoring reference position of the label paper must be readjusted. In this case, the position of the label paper deviation detector must be adjusted along the length of the guide rod 2. There are two specific situations:

[0054] First, when it is necessary to adjust the trademark paper offset detector to move upward along the guide rod 2, first loosen the screw 7, then twist the adjusting screw 5 in the counterclockwise direction, and according to the position to be adjusted for adjusting the trademark paper offset detection, the corresponding adjusting screw 5 is screwed out of the fixed base 4 by a certain length, and the spring 6 is reset to a certain length. During the spring reset process, the movable base 1 is simultaneously pushed to move upward along the length direction of the guide rod 2 by a certain distance (that is, the trademark paper offset detector moves upward along the length direction of the guide rod 2 by a certain distance). When it is adjusted to the set position, tighten the screw 7 again to make it rest against the outer peripheral wall of the guide rod 2 again, and the adjustment is completed; the distance the movable base 1 moves upward along the guide rod 2 is equal to the length of the adjusting screw 5 screwed out of the fixed base 4, and is also equal to the length of the spring 6 reset;

[0055] Second, when it is necessary to adjust the trademark paper offset detector to move downward along the guide rod 2, first loosen the screw 7, then twist the adjusting screw 5 in the clockwise direction, and according to the position that needs to be adjusted to adjust the trademark paper offset detection, the adjusting screw 5 is screwed into the fixed base 4 for a certain length, and the spring 6 is compressed for a certain length. During the spring compression process, the movable base 1 synchronously moves downward along the length direction of the guide rod 2 by a certain distance (the synchronous trademark paper offset detector moves downward along the length direction of the guide rod 2 by a certain distance). After adjusting to the set position, tighten the screw 7 again so that it rests against the outer wall of the guide rod 2 again to complete the adjustment; the distance that the movable base 1 moves downward along the guide rod 2 is equal to the length of the adjusting screw 5 screwed into the fixed base 4, and is also equal to the increase in the compression of the spring 6.

[0056] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and detail without departing from the scope defined by the claims of the present application; the dimensions described in the drawings and embodiments are not related to specific physical objects and are not used to limit the scope of protection of the present application.
