Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic glue coating, in particular to a metal photovoltaic flat glue nozzle with a glue outlet angle that can be freely adjusted. Background Art

[0002] In the photovoltaic glue coating industry, photovoltaic flat glue nozzles are a common glue coating structure. However, the current photovoltaic flat glue nozzles are relatively simple, with a fixed glue outlet angle, which cannot adapt to the changing glue coating conditions. After changing the process, only photovoltaic flat glue nozzles with other slopes can be replaced, which not only increases the cumbersome steps of manual disassembly and replacement, but also increases the consumption and waste of the glue nozzle and the pressure of cleaning.

[0003] At the same time, based on the existing photovoltaic flat glue nozzles, most of them are made of plastic, and the main plastic materials are polypropylene and polyethylene. Under high pressure, bulging and cracking of the side edges will occur, and the service life is short. For the production line, it needs to be replaced once a shift. It is a consumable. Frequent replacement and excessive consumption lead to increased costs. You can refer to the relevant patent with patent number CN218190721U. Although the strength is improved in shape, when the viscosity of the glue is too large, the flow rate remains unchanged and the flow channel area changes from large to small, the pressure will change from small to large, resulting in greater pressure on the inner wall of the flat glue nozzle, increased stress on the edge of the inner wall, and it is still easy to bulge and cracking of the side edges, which seriously affects the production capacity. Of course, the metal flat glue nozzles on the market can increase the service life, but most of them are made by welding or integrated, and the production cost is slightly higher, so the purchase price is relatively expensive. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a metal photovoltaic flat glue nozzle with a freely adjustable glue outlet angle, which can quickly adjust the glue outlet angle of the glue nozzle and appropriately save costs while improving the strength of the glue nozzle.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A metal photovoltaic flat glue nozzle with a freely adjustable glue outlet angle comprises a metal flat glue tube with a glue outlet oblique opening at the lower end, a glue nozzle head arranged at the upper end of the metal flat glue tube, and a sliding sleeve with an oblique opening at the lower end;

[0007] The sliding sleeve is slidably connected to the lower part of the metal flat rubber hose and is locked by a tightening screw. The glue outlet bevel of the metal flat rubber hose and the bevel of the sliding sleeve have the same inclination direction but different inclinations. When the sliding sleeve slides up and down relative to the metal flat rubber hose, the overall glue outlet angle can be adjusted and changed.

[0008] Furthermore, the metal flat rubber hose and the nozzle head are made of stainless steel.

[0009] Furthermore, a scale is provided on the outer side wall of the metal flat rubber hose.

[0010] Furthermore, a sealing gasket is provided on the upper port of the nozzle head.

[0011] Furthermore, a plurality of sealing rings are embedded on the inner wall of the sliding sleeve.

[0012] Furthermore, the sealing ring is provided with two upper and lower ones.

[0013] Furthermore, the upper end of the metal flat rubber tube is embedded in the nozzle head and bonded by mixed glue.

[0014] Furthermore, the inner wall of the nozzle head is funnel-shaped.

[0015] By adopting the above technical solution, the utility model has the following beneficial effects:

[0016] 1. The utility model combines and superimposes a sliding sleeve with an oblique opening and a metal flat rubber hose with an oblique opening for glue outlet, so that the sliding sleeve is slidably sleeved on the lower part of the metal flat rubber hose and locked by a tightening screw, so that the position of the sliding sleeve can be adjusted up and down after loosening the tightening screw, thereby changing and adjusting the angle of the glue outlet formed by the sliding sleeve and the metal flat rubber hose. This is convenient and quick to operate, can be flexibly applied to various different glue coating conditions, reduces the pressure of frequent manual replacement, and reduces the loss cost of the glue nozzle.

[0017] 2. The utility model uses stainless steel as the main material of the metal flat rubber hose and the nozzle head, which greatly improves the strength, is not easy to deform, increases its service life, and can also cope with the situation of excessive glue discharge pressure, up to 200Bar. The high hardness of the metal can effectively prevent bulging and cracking of the nozzle and improve the glue discharge accuracy; and the metal flat rubber hose and the nozzle head are bonded by mixed glue. The metal flat rubber hose can directly use existing standard parts, so the cost is less than 1 / 4 of the existing metal flat rubber nozzles, which can greatly save costs.

[0025] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0026] like Figure 1-5 As shown, in this embodiment, a metal photovoltaic flat glue nozzle with a freely adjustable glue outlet angle is provided, which is mainly composed of a metal flat rubber tube 1, a glue nozzle head 2, a sliding sleeve 3, a tightening screw 4 and other components. Among them, the glue nozzle head 2 is connected and arranged at the upper end of the metal flat rubber tube 1, and the inner wall of the glue nozzle head 2 is funnel-shaped, which is convenient for the glue to flow down; a sealing gasket 20 is arranged at the upper end of the glue nozzle head 2, which can be compressed when in use, so as to play a sealing role when installed on the valve body.

[0027] Specifically, the lower end of the metal flat rubber tube 1 has an oblique opening for discharging glue, and the lower end of the sliding sleeve 3 also has an oblique opening, and the sliding sleeve 3 is slidably sleeved on the lower part of the metal flat rubber tube 1 and locked by the tightening screw 4. The metal flat rubber tube 1 can be tightly attached to the wall of the metal flat rubber tube 1 by tightening the tightening screw 4, and the position of the sliding sleeve 3 can be adjusted by sliding up and down by loosening the tightening screw 4. It is worth mentioning that the oblique opening of the metal flat rubber tube 1 and the oblique opening of the sliding sleeve 3 are in the same inclination direction, for example Figure 3 The sliding sleeve 3 is inclined to the left in the figure, but the different inclinations mean different glue outlet angles. Therefore, when the sliding sleeve 3 slides up and down relative to the metal flat rubber tube 1, the overall glue outlet angle can be adjusted and changed.

[0028] refer to Figure 5 In this embodiment, the upper port of the nozzle head 2 is directly installed on the valve body for use. When applying glue, the photovoltaic frame 6 product is applied with glue through the glue outlet formed by the metal flat rubber tube 1 and the sliding sleeve 3.

[0029] In order to prevent glue from penetrating from the sliding sleeve 3, two upper and lower sealing rings 30 are embedded and assembled on the inner wall of the sliding sleeve 3, thereby achieving a good double sealing effect.

[0030] When there are many different working conditions of photovoltaic frame 6 products, it is necessary to flexibly adjust the angle of the glue outlet. Figure 4In the comparison state when adjusting the angle, the sliding sleeve 3 gradually slides up from left to right, corresponding to three different superimposed glue discharge angles of A, B, and C. The glue discharge angles of A, B, and C are also increasing in sequence, where A is the minimum value of the glue discharge angle, corresponding to the critical point between the lower sealing ring 30 and the upper end of the glue discharge oblique opening of the metal flat rubber tube 1, and C is the maximum value of the glue discharge angle, corresponding to the oblique opening of the sliding sleeve 3 being critical above the oblique opening of the metal flat rubber tube 1. Therefore, the angle range of this embodiment can be arbitrarily adjusted between A and C. Of course, the oblique opening directions and respective inclination sizes of the metal flat rubber tube 1 and the sliding sleeve 3 of this embodiment are only one of the implementation methods, which can be a variety of deformation combinations, and can be selected and manufactured according to more working conditions in a wider range.

[0031] Through the above design, it can be seen that in this embodiment, the position of the sliding sleeve 3 can be adjusted up and down only by loosening the tightening screw 4, thereby changing the angle of the glue outlet formed by the adjusting sliding sleeve 3 and the metal flat rubber hose 1. This operation is convenient and fast, and can be flexibly applied to various different gluing conditions, reducing the pressure of frequent manual replacement and reducing the loss cost of the glue nozzle.

[0032] Specifically, in order to improve the strength of the structure of this embodiment, the metal flat rubber hose 1 and the nozzle head 2 are both made of stainless steel, and the sliding sleeve 3 has little effect and can be made of stainless steel or other cost-saving materials. In this way, stainless steel is selected as the main material of the metal flat rubber hose 1 and the nozzle head 2, which greatly improves the strength, is not easy to deform, and increases its service life. It can also cope with the situation of excessive glue discharge pressure, which can reach up to 200Bar. The high hardness of the metal can effectively prevent the nozzle from bulging and cracking, and improve the glue discharge accuracy.

[0033] In order to save manufacturing costs, the upper end of the metal flat rubber hose 1 in this embodiment is embedded in the nozzle head 2 and bonded by AB mixed glue without leaving any gaps. In this way, the metal flat rubber hose 1 and the nozzle head 2 are bonded by the mixed glue. The metal flat rubber hose 1 can directly use existing standard parts, so the cost is less than 1 / 4 of the existing metal flat rubber nozzles, which can greatly save costs.

[0034] In addition, refer to Figure 2 In this embodiment, a scale ruler 5 is also provided on the outer wall of the metal flat rubber hose 1. The scale ruler 5 can be made of spray paint or carving, etc., and the scale value corresponding to each working condition is recorded, which can facilitate quick adjustment to the required angle position next time, which is convenient and saves trouble and adjustment time.
