Description

Technical Field

[0001] The utility model relates to the technical field of mechanical components of tobacco packaging machines, and particularly relates to a novel flange at the outlet of the fourth wheel of a ZB25 packaging machine. Background Art

[0002] In the actual production process, due to its mechanical principle and structural characteristics, the push rod of the ZB25 small box packaging machine reciprocates at a very high frequency, and the rated design operating efficiency reaches 400 revolutions per minute, which means that the push rod reciprocates up to 336,000 times a day. However, this high-frequency operation combined with its unique flange structure often results in poor sealing effect, thus causing serious oil leakage, greatly increasing the maintenance cost, seriously affecting the production efficiency, and also affecting the quality of cigarette pack products.

[0003] In the prior art, an O-ring is usually used to seal between the flanges as a whole. However, the O-ring easily causes the contact surface between the flanges to be uneven, resulting in gaps and unsealing between the flanges, and further causing unsealing between the oil seal and the push rod. After long-term operation, oil leakage will occur at the push rod part. Summary of the Utility Model

[0004] In view of this, the utility model provides a novel flange at the outlet of the fourth wheel of a ZB25 packaging machine, which can solve the technical problem that in the prior art, using an O-ring easily causes the contact surface between the flanges to be uneven, resulting in gaps and unsealing between the flanges, and oil leakage will occur after long-term operation.

[0005] To solve the above technical problem, the technical solution of the utility model is as follows:

[0006] A novel flange at the outlet of the fourth wheel of a ZB25 packaging machine, which includes flange A and flange B that is cooperatively connected with it. Flange A is provided with a central hole, and a sealing step is arranged inside the central hole. Polyurethane sealant is applied to the sealing step so that the surface of the sealing step can be closely attached to the upper top surface of flange B. A plurality of threaded holes Ⅰ are opened at the outer edge of flange A, a sealing ring is arranged on the upper side wall surface of flange B so that the side wall surface of the sealing ring can be closely attached to the side wall surface of the central hole. A plurality of threaded holes Ⅱ corresponding to the positions of the threaded holes Ⅰ are opened at the outer edge of flange B. Flange A and flange B are fastened together through the cooperation of fastening bolts with the threaded holes Ⅰ and threaded holes Ⅱ.

[0007] As an improvement of the above technical solution, the number of the threaded holes Ⅰ and the threaded holes Ⅱ is set to four.

[0008] Compared with the prior art, the technical solution of the utility model has the following beneficial effects:

[0009] The utility model has the characteristics of reasonable design, strong practicability, good sealing performance, etc. The polyurethane sealant is used to fill the gap between the upper top edges of flange A and flange B, providing the first layer of sealing protection between flange A and flange B. By setting a sealing ring on the upper side wall of flange B, flange A and flange B are more closely fitted together, providing the second layer of sealing protection between flange A and flange B, avoiding the occurrence of oil leakage problems caused by insufficient sealing, effectively improving the daily oil leakage problems, and solving the hidden dangers of equipment maintenance; by adding multiple fastening bolts used in conjunction with threaded hole Ⅰ and threaded hole Ⅱ, the fixing effect between flange A and flange B is more stable. While further improving the sealing effect, the probability of the gap between flange A and flange B increasing due to mechanical movement is reduced, increasing the reliability of the equipment;

[0020] As Figures 1 to 4 shown, a new type of flange at the outlet of the fourth wheel of the ZB25 packaging machine

[0021] It includes flange A1 and flange B2 which is cooperatively connected with it. The flange A1 is provided with a central hole 101. A sealing step 102 is arranged inside the central hole 101. Polyurethane sealant is applied to the sealing step 102 so that the surface of the sealing step 102 can be closely attached to the top surface of the upper part 201 of flange B. A plurality of threaded holes I103 are opened at the outer edge of the flange A1. A sealing ring is arranged on the side wall surface of the upper part 201 of the flange B so that the side wall surface of the sealing ring can be closely attached to the side wall surface of the central hole 101. A plurality of threaded holes II202 corresponding to the positions of the threaded holes I103 are opened at the outer edge of the flange B2. The flange A1 and the flange B2 are fastened together through the cooperation of fastening bolts with the threaded holes I103 and the threaded holes II202;

[0022] In the embodiment of the present utility model, the polyurethane sealant has high tensile strength, excellent elasticity, wear resistance, oil resistance and cold resistance. The elongation at break of the polyurethane sealant can reach about 900%. Therefore, using the polyurethane sealant can extend the sealing life between the flange A1 and the flange B2;

[0023] In the embodiment of the present utility model, the diameter of the upper part 201 of the flange B is smaller than the diameter of the central hole 101 of the flange A1. There is a chamfer at the top edge of the upper part 201 of the flange B, so that when the top of the upper part 201 of the flange B is aligned and enters the central hole 101 of the flange A1 and contacts the surface of the sealing step 102 of the flange A1, there is a gap of 0.02 mm between the side wall surface of the central hole 101 of the flange A1 and the top edge of the upper part 201 of the flange B, and there is a gap of 0.01 mm between the side wall surface of the central hole 101 of the flange A1 and the side wall surface of the upper part 201 of the flange B. The polyurethane sealant can fill the gap between the flange A1 and the top edge of the upper part 201 of the flange B, providing the first layer of sealing protection between the flange A1 and the flange B2. By setting a sealing ring on the side wall surface of the upper part 201 of the flange B, the flange A1 and the flange B2 are more closely fitted together, providing the second layer of sealing protection between the flange A1 and the flange B2, avoiding the occurrence of oil leakage problems caused by insufficient sealing, effectively improving the daily oil leakage problem, and solving the hidden danger of equipment maintenance;

[0024] In the embodiment of the present utility model, four threaded holes Ⅰ103 and threaded holes Ⅱ202 are provided. The arrangement of multiple fastening bolts between the flange A1 and the flange B2 makes the fixing effect more stable. While further improving the sealing effect, it reduces the probability of the gap between the flange A1 and the flange B2 increasing due to mechanical movement, and increases the reliability of the equipment.

[0025] Combined with the above content, the working principle of the present utility model is as follows:

[0026] When sealing between the flange A1 and the flange B2, first, a sealing ring is sleeved on the side wall surface of the upper part 201 of the flange B. Subsequently, polyurethane sealant is applied to the sealing step 102 of the flange A1. The top surface of the upper part 201 of the flange B gradually approaches and contacts the surface of the sealing step 102 of the flange A1. At this time, the polyurethane sealant can fill the gap between the flange A1 and the top edge of the upper part 201 of the flange B, forming the first layer of sealing protection between the flange A1 and the flange B2. As the sealing ring on the side wall surface of the upper part 201 of the flange A1 and the flange B contacts, the flange A1 and the flange B2 are more closely fitted together, providing the second layer of sealing protection between the flange A1 and the flange B2, effectively reducing the risk of oil leakage. Finally, through the cooperation of the fastening bolts with the threaded holes Ⅰ103 and the threaded holes Ⅱ202 in sequence, the fixing effect between the flange A1 and the flange B2 is more stable, further improving the sealing effect.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
