Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment, in particular to a sealing suction and conveying device for a soft box packaging machine. Background Art

[0002] The packaging unit of a certain brand of Diamond often has the phenomenon of small box seal deviation and crookedness during production. When the appearance imaging detection device cannot completely and effectively eliminate the defects, cigarette packs with quality defects in the seals will have the potential quality risks of entering the consumer market, which will not only put invisible pressure on quality management, but also cause waste of production costs and seriously affect production efficiency.

[0003] According to the material consumption standard issued by the group, the maximum consumption of a certain brand of Diamond small box label paper is 2515 sheets / box. In the actual production process, due to the rejection of unqualified products caused by crooked seals, the frequent shutdown of production equipment due to unstable operation and excessive rejection, the consumption of small boxes of this brand has been wasted in the production process. The workshop is based on the long-term development of the brand and puts forward requirements in terms of quality assurance, efficiency improvement and other aspects.

[0004] The seal supply system of the YB25 soft box packaging machine includes various components and mechanisms for the suction, delivery and positioning of the seal. Figure 1 The seal suction wheel 100 is connected to the negative pressure pipeline. After sucking a seal from the seal paper library by negative pressure, the seal is closely attached to the seal suction wheel 100. The seal suction wheel 100 rotates counterclockwise ( Figure 1 The seal is then fed to the first paper guide roller 200 (fan-shaped) and the paper pressing roller 300. Figure 1 The paper is transported downward after the guide of the paper pressing wheel 300 is turned 90 degrees, and after being glued on both sides of the seal by the gluing wheel, it is transported downward to the lower paper reference box by the second and third paper guide wheels.

[0005] In the prior art, the negative pressure transmission channel of the seal is not tightly sealed, resulting in negative pressure leakage. In addition, there is a section of negative pressure hose in the negative pressure pipeline inside the chassis, which is prone to aging and cracking after long-term use, resulting in negative pressure leakage; and this section of negative pressure hose is bent in many places, which will cause pressure loss. Therefore, the main problems in the process of sealing and paper delivery of the YB25 soft box packaging machine are: during the sealing suction process, the vacuum pressure of the suction wheel is low, resulting in poor sealing paper suction or poor delivery. Summary of the invention

[0006] In order to solve the above problems, the present application provides a sealing suction and conveying device for a soft box packaging machine, which aims to ensure the stability of the vacuum pressure through the connection method of the internal and external threads of the suction wheel. The design of the negative pressure pipeline not passing through the inside of the chassis increases the vacuum pressure at the suction wheel, and facilitates the disassembly and cleaning of the negative pressure pipeline.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] The present application provides a sealing suction and conveying device for a soft box packaging machine, comprising a suction wheel, a chassis and a negative pressure pipeline, wherein the suction wheel comprises a negative pressure connection port, the inner surface of the negative pressure connection port is provided with an internal thread, and the outer surface thereof is provided with an external thread;

[0010] The chassis is located on one side of the suction wheel, and the negative pressure pipe is located outside the chassis. The negative pressure pipe inside the chassis in the prior art is replaced with an external negative pressure pipe, that is, the negative pressure pipe does not pass through the inside of the chassis, which reduces the loss of vacuum pressure during the transportation process due to bending or aging of the negative pressure pipe inside the chassis, increases the vacuum pressure at the suction wheel, and facilitates the disassembly and cleaning of the negative pressure pipe.

[0011] As an improvement of the above scheme, the seal suction and conveying device of the soft box packaging machine also includes a first paper guide wheel, which is located below the suction wheel and has a rotation direction opposite to that of the suction wheel. The suction wheel transfers the seal to the first paper guide wheel by rotating.

[0012] As an improvement of the above solution, the first paper guide wheel is made of polyurethane. The surface material of the first paper guide wheel is changed from alloy steel to polyurethane, which increases the friction between the first paper guide wheel and the seal and ensures the running stability of the seal during transportation.

[0013] As an improvement of the above solution, the sealing suction and conveying device of the soft box packaging machine includes a negative pressure conveying channel, the negative pressure conveying channel includes the negative pressure pipeline, and the negative pressure pipeline is provided with a solenoid valve.

[0015] When the negative pressure is sufficient, the diameter of the negative pressure pipe is 6 mm, and the suction wheel is connected to the negative pressure pipe through the internal thread.

[0016] As an improvement of the above solution, the outer diameter of the negative pressure connection port is 8 mm;

[0017] When the negative pressure is insufficient, the diameter of the negative pressure pipe is 10 mm, and the suction wheel is connected to the negative pressure pipe through the external thread.

[0018] As an improvement of the above solution, the negative pressure connection port and the negative pressure pipeline are connected via a rotary joint, one end of the rotary joint is threadedly connected to the negative pressure connection port, and the other end is connected to the negative pressure pipeline.

[0019] The beneficial effects brought by the utility model are:

[0020] The present application provides a sealing suction and conveying device for a soft box packaging machine, which transforms the suction wheel into a variable pipe diameter connection method through the internal and external threads of the negative pressure connecting port, greatly increasing the applicability and practicality of the suction wheel and ensuring the stability of the vacuum pressure in the suction wheel; the design that the negative pressure pipeline does not pass through the inside of the chassis reduces the loss of vacuum pressure during the conveying process due to bending or aging of the negative pressure pipeline located in the chassis, increases the vacuum pressure at the suction wheel, and facilitates the disassembly and cleaning of the negative pressure pipeline.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] See also Figure 2 and 3 The present application provides a sealing suction and conveying device for a soft box packaging machine, comprising a suction wheel 1, a first paper guide wheel 2, a negative pressure pipe and a chassis.

[0030] The suction wheel 1 is provided with a negative pressure connection port 11 on the basis of the original suction wheel 100, and the negative pressure hole of the original suction wheel 100 is sealed and blocked when in use. The inner and outer surfaces of the negative pressure connection port 11 are respectively provided with internal threads and external threads, and the internal thread connection mode or the external thread connection mode is selected according to the pressure of the negative pressure.

[0031] The negative pressure pipe is communicated with the negative pressure connection port 11, and the negative pressure is transmitted to the suction wheel 1 through the negative pressure pipe to adsorb the seal.

[0032] The outer surface of the first paper guide wheel 2 is made of polyurethane. In the prior art, the surface material of the first paper guide wheel 2 is alloy steel. In this embodiment, the surface material of the first paper guide wheel 2 is changed to polyurethane. The friction coefficient of polyurethane is greater than the friction coefficient of alloy steel, thereby increasing the friction between the first paper guide wheel 2 and the seal, thereby ensuring the operational stability of the seal during transportation. The first paper guide wheel 2 is located below the suction wheel 1 and is adjacently arranged. Its rotation direction is opposite to that of the suction wheel 1. The suction wheel 1 transfers the seal to the first paper guide wheel 2 by rotating.

[0033] The negative pressure pipeline is provided with a solenoid valve, and the on-off of the negative pressure pipeline is controlled by the solenoid valve.

[0034] The sealing suction and conveying device of the soft box packaging machine mentioned above also includes a chassis, and the chassis is located between the negative pressure generator and the suction wheel, and the negative pressure pipe is located outside the chassis. In the prior art, the negative pressure pipe passes through the interior of the chassis, which is not easy to repair and clean. This section of the negative pressure pipe is a rubber hose, which is prone to aging and cracking after long-term use, resulting in negative pressure leakage. Moreover, the negative pressure pipe located in the chassis is installed therein in a manner of multiple bends, which easily causes the loss of negative pressure during the conveying process. In this embodiment, the negative pressure pipe inside the chassis in the prior art is changed to an external negative pressure pipe, that is, the negative pressure pipe does not pass through the interior of the chassis, and this section of the negative pressure pipe does not need to be bent again, which reduces the loss of vacuum pressure during the conveying process and increases the vacuum pressure at the suction wheel 1. At the same time, it is easy to disassemble and clean the negative pressure pipe, and it can basically achieve maintenance-free, avoiding the daily maintenance work of replacing the sealing ring and negative pressure management.

[0035] The sealing suction conveying device of the soft box packaging machine of this embodiment includes a negative pressure conveying channel, and negative pressure is provided to the negative pressure conveying channel by a negative pressure generator. The negative pressure pipeline is a part of the negative pressure conveying channel, that is, a pipe section that provides negative pressure to the suction wheel. A negative pressure gauge is installed at the input end of the negative pressure conveying channel, that is, the negative pressure gauge is installed at the negative pressure input end of the sealing suction conveying device of the soft box packaging machine, and is used to monitor whether the negative pressure entering the sealing suction conveying device of the soft box packaging machine is sufficient.

[0036] Furthermore, the negative pressure connection port 11 has a length of 8 mm, an inner diameter of 5 mm, and an outer diameter of 8 mm.

[0037] Generally, under the premise of sufficient negative pressure, the diameter of the negative pressure pipe is 6mm, which can meet the production requirements. At this time, the suction wheel 1 is connected to the negative pressure pipe by means of an internal thread. Furthermore, the negative pressure connection port 11 is connected to the negative pressure pipe by a rotary joint, one end (M5 thread) of the rotary joint is connected to the internal thread of the negative pressure connection port 11, and the other end is connected to the negative pressure pipe.

[0038] In the case of insufficient negative pressure, the diameter of the negative pressure pipe is 10mm, and the negative pressure air intake can be increased to meet production. At this time, the suction wheel 1 is connected to the negative pressure pipe by an external thread connection. Further, the negative pressure connection port 11 is sequentially connected with a thread conversion device, a rotary joint and a negative pressure pipe. One end of the thread conversion device is externally connected to the external thread (M8 thread) of the negative pressure connection port 11, and the other end is internally connected to a 1 / 8 (thread is 9.5mm) rotary joint. The other end of the rotary joint is connected to the negative pressure pipe.

[0039] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
