[0029] The utility model will be further described in detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the utility model, and not limited to the utility model. In addition, it should be noted that, in order to facilitate the description, only the part related to the utility model is shown in the drawings, not all structures.

[0032] In the description of the embodiment, the orientation or position relationship of the terms "on", "under", "right", "left" and the like is based on the orientation or position relationship shown in the drawing, only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0033] As Figure 1 As shown in the prior art, the air path system of the splicing machine is connected with the positive pressure supply device, and through two negative pressure generators 100, the positive pressure can be converted into negative pressure and provided to the inner liner paper splicing mechanism and the inner frame paper splicing mechanism respectively.The inner liner paper splicing mechanism includes a first splicing assembly 22, i.e., an inner liner paper movable folder and an inner liner paper fixed folder, which can cooperate to realize the splicing action of bonding the adhesive tape on two sections of inner liner paper to realize the splicing of the inner liner paper.The inner frame paper splicing mechanism includes a second splicing assembly 32, i.e., an inner frame paper movable folder and an inner frame paper fixed folder, which can cooperate to realize the splicing action of bonding the adhesive tape on two sections of inner frame paper to realize the splicing of the inner frame paper.

[0034] In the process of supplying positive pressure, if the impurities in the air are more, the negative pressure generator 100 will be blocked, causing failure. And in the splicing process, because the adhesive tape, inner liner paper, inner frame paper need to be adsorbed and positioned, so the floating foam, material debris, dust in the air and other impurities will be sucked into the air path system, thereby causing the blockage of holes, pipelines, valve bodies and detector joints caused by impurities, resulting in limited negative pressure, limited on-off speed, limited detection accuracy and other problems, such as the frequent failure of the negative pressure generator 100 described above, insufficient negative pressure and other phenomena.

[0035] Therefore, as Figure 2 shown, the utility model provides a splicing machine which can avoid the above failure phenomenon. Specifically, the splicing machine comprises a negative pressure supply pipeline 11, a three-way valve 12 and an inner liner paper splicing mechanism. Among them, one end of the negative pressure supply pipeline 11 is connected with a negative pressure centralized supply device, and the other end is connected to the three-way valve 12. The three-way valve 12 has a first opening, a second opening and a third opening connected in communication, wherein the first opening is connected to the other end of the negative pressure supply pipeline 11, the second opening is connected to the inner liner paper splicing mechanism, and the third opening is connected to the inner frame paper splicing mechanism. In the splicing machine, the inner liner paper splicing mechanism also comprises an inner liner paper movable folder and an inner liner paper fixed folder, and the inner frame paper splicing mechanism also comprises an inner frame paper movable folder and an inner frame paper fixed folder. The structure, working principle and driving mode of the inner liner paper splicing mechanism and the inner frame paper splicing mechanism are the same as those in the prior art, and the utility model will not be described in detail.

[0036] By supplying negative pressure to the inner liner paper splicing mechanism and the inner frame paper splicing mechanism through the negative pressure supply pipeline 11, the failure of the negative pressure generator 100 caused by poor air quality during positive pressure supply can be avoided, thereby avoiding the shutdown maintenance of the splicing machine by the negative pressure generator 100, and ensuring the efficiency of the splicing machine. And compared with using the negative pressure generator 100 to drive the inner liner paper splicing mechanism and the inner frame paper splicing mechanism, centralized negative pressure supply can avoid the insufficient negative pressure phenomenon caused by simultaneous splicing, thereby reducing the possibility of splicing failure, avoiding the phenomenon of rethreading, and further improving the efficiency of the splicing machine.

[0037] Specifically, as Figure 2As shown, in the embodiment, the inner liner splicing mechanism comprises a first air path 20, a first negative pressure on-off valve 21 and a first splicing assembly 22. The one end of the first air path 20 is connected to the second opening, and the other end of the first air path 20 is connected to the first splicing assembly 22, so that the negative pressure can be supplied to the first splicing assembly 22 through the first air path 20 to realize the splicing of the inner liner. The first negative pressure on-off valve 21 is arranged between the three-way valve 12 and the first splicing assembly 22 on the first air path 20, and the supply of negative pressure can be controlled through the first negative pressure on-off valve 21. For example, when the first negative pressure on-off valve 21 is turned on, under the action of negative pressure, air can enter the first splicing assembly 22 from the first air path 20 and flow into the three-way valve 12 and the negative pressure centralized supply device through the first air path 20. At this time, the first splicing assembly 22 can realize corresponding adsorption and splicing actions on the adhesive tape and the inner liner. When the first negative pressure on-off valve 21 blocks the first air path 20, the first splicing assembly 22 loses the continuous supply of negative pressure at this time.

[0038] Through the first negative pressure on-off valve 21, before splicing, the first air path 20 can be blocked to avoid impurities entering the first splicing assembly 22 due to negative pressure, thereby causing blockage and other phenomena. During splicing (for example, during the process of unwinding the adhesive tape), the first negative pressure on-off valve 21 remains in the on state until the splicing is completed. After splicing is completed, that is, the adhesive tape is bonded to the surface of the inner liner and leaves the first splicing assembly 22, the first negative pressure on-off valve 21 blocks the first air path 20 again, thereby ensuring the cleanliness of the air path of the entire splicing machine.

[0039] More specifically, in the embodiment, the first negative pressure on-off valve 21 selects the SMC VT325V-035D electromagnetic valve, which is driven by 24V direct current and has a relatively fast response speed, so that it can be quickly turned on when a conduction signal is obtained, thereby ensuring that the adhesive tape is adsorbed immediately when it is first contacted, and preventing the adhesive tape from being adsorbed into dust due to premature adsorption or from being adsorbed out of place due to adsorption delay.

[0040] Continuing to refer to Figure 2 As shown, in the embodiment, the inner liner splicing mechanism further comprises a first flow control valve 23, which is arranged between the first negative pressure on-off valve 21 and the first splicing assembly 22 on the first air path 20. The first flow control valve 23 can control the flow of air entering the first air path 20 under the action of negative pressure, thereby avoiding the phenomenon of excessive adsorption force due to excessive negative pressure and ensuring the normal performance of the splicing action.

[0041] Further, in the present embodiment, the inner liner splicing mechanism further comprises a first pressure detection gauge 24, which is connected to the first air path 20 and between the first flow control valve 23 and the first splicing assembly 22. Through the first pressure detection gauge 24, the pressure in the first splicing assembly 22 can be detected, so as to reflect whether the normal adsorption is achieved. Preferably, the first pressure detection gauge 24 also adopts a detection gauge with a working voltage of 24V, such as a DP-100 vacuum negative pressure gauge of Pansonic, so as to have the same working voltage (including the voltage of input and output signals) with the first negative pressure on-off valve 21, and both of them also adopt direct current driving, thereby the electrical design of the inner liner splicing mechanism can be simplified.

[0042] Preferably, the inner liner splicing mechanism further comprises a first positive pressure on-off valve 25, one end of which is connected to the first air path 20 and between the first flow control valve 23 and the first splicing assembly 22, and the other end of which is connected with a positive pressure supply device. In the long-term operation process, dust and other impurities inevitably enter the inner liner splicing mechanism, and if not cleaned in time, the inner liner splicing mechanism will be gradually eroded by these impurities over a long period of time, which will affect the stability of the inner liner splicing mechanism and thus affect the stability of the splicing process. Through the first positive pressure on-off valve 25, air can be blown to the inner liner splicing mechanism, so as to blow out the impurities in the inner liner splicing mechanism, realize automatic cleaning, and reduce the frequency and cost of maintenance.

[0043] Continuing to refer to Figure 2 In the present embodiment, the inner frame paper splicing mechanism comprises a second air path 30, a second negative pressure on-off valve 31 and a second splicing assembly 32. One end of the second air path 30 is connected to the third opening of the three-way valve 12, and the other end of the second air path 30 is connected to the second splicing assembly 32, so that negative pressure can be supplied to the second splicing assembly 32 through the second air path 30 to realize the splicing action of the inner frame paper. The second negative pressure on-off valve 31 is arranged in the second air path 30 and between the three-way valve 12 and the second splicing assembly 32, and the supply of negative pressure can be controlled through the second negative pressure on-off valve 31. For example, when the second negative pressure on-off valve 31 is turned on, air can enter the second splicing assembly 32 under the action of negative pressure, and flow into the three-way valve 12 and the negative pressure centralized supply device through the second air path 30. At this time, the second splicing assembly 32 can realize the corresponding adsorption and splicing action of the adhesive tape and the inner liner paper. When the second negative pressure on-off valve 31 blocks the second air path 30, the second splicing assembly 32 loses the continuous supply of negative pressure.

[0044] Similar to the inner liner paper splicing mechanism, the inner frame paper splicing mechanism also comprises a second flow control valve 33, which is arranged in the second air path 30 and located between the second negative pressure on-off valve 31 and the second splicing assembly 32. The second flow control valve 33 can control the flow of air entering the second air path 30 under the action of negative pressure, thereby avoiding the phenomenon of excessive suction force caused by excessive negative pressure and ensuring the normal operation of the splicing action.

[0045] Optionally, the inner frame paper splicing mechanism also comprises a second pressure detection table 34, which is connected to the second air path 30 and connected between the second flow control valve 33 and the second splicing assembly 32. The second negative pressure on-off valve 31 also adopts an SMC VT325V-035D electromagnetic valve, and the second pressure detection table 34 also adopts a Pansonic DP-100 vacuum negative pressure table, so that the inner liner paper splicing mechanism and the inner frame paper splicing mechanism can work in the same voltage and current environment, thereby further simplifying the electrical design of the splicing machine.

[0046] Preferably, the inner frame paper splicing mechanism also comprises a second positive pressure on-off valve 35, one end of which is connected to the second air path 30 and connected between the second flow control valve 33 and the second splicing assembly 32, and the other end of which is also connected with a positive pressure supply device. During a long period of operation, dust and other impurities will inevitably enter the inner frame paper splicing mechanism. If not cleaned in time, the inner frame paper splicing mechanism will be gradually eroded by these impurities over a long period of time, affecting the stability of the inner frame paper splicing mechanism and thus affecting the stability of the splicing process. By the second positive pressure on-off valve 35, air can be blown to the inner frame paper splicing mechanism, thereby blowing out the impurities in the inner frame paper splicing mechanism, achieving automatic cleaning and reducing the frequency and cost of maintenance.

[0047] Further optionally, a positive pressure flow regulating valve 36 is connected between the second positive pressure on-off valve 35 and the second air path 30, which can adjust the blowing force of the inner frame paper splicing mechanism, thereby avoiding excessive blowing force causing damage to the inner frame paper and other materials.
