Description

Technical Field

[0001] The utility model belongs to the technical field of filtration, and in particular relates to a flocking glue liquid filtering component. Background Art

[0002] Flocking glue refers to the adhesive used in electrostatic flocking. The principle of flocking is to use the physical properties of like charges repelling and opposite charges attracting to give the flock a negative charge. When the object to be flocked is placed at zero potential or grounded, the flock is attracted to the object at a different potential. Usually, flocking glue is applied to the object, and the flock will stick vertically to the object.

[0003] During the production process, various impurities may enter the glue solution, including but not limited to incompletely mixed solid raw materials, foreign particles, and gel. The presence of these impurities not only affects the quality of the glue solution, but may also lead to unstable or substandard product performance. Therefore, filtration of the glue solution is an essential step in the glue solution preparation process.

[0004] In the prior art, a filter is usually added to the glue liquid flow channel to filter out impurity particles contained in the glue liquid through the mesh holes on the filter screen. The existing filtration technology can only filter the glue liquid once, and the filtration effect is poor. The purity of the glue liquid after filtration is not high; moreover, after a long period of filtration, the disassembly and cleaning steps of the filter screen are relatively complicated, which prolongs the glue liquid filtration cycle. Utility Model Content

[0005] The utility model provides a flocking glue liquid filtering component, which solves the defects of the existing filtering means, such as poor filtering effect and inconvenient cleaning of the filter screen.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a flocking glue liquid filtering component, which includes:

[0007] A sleeve mechanism, comprising a sleeve, an upper accommodating groove provided at the bottom of the sleeve, and a glue feeding unit and a glue discharging unit provided on both sides of the sleeve and connected to the upper accommodating groove;

[0008] The pressing mechanism includes a pressing tube abutting against the bottom of the sleeve and a screen cylinder elastically arranged on the side of the pressing tube close to the sleeve. The screen cylinder is located in the upper accommodating groove, and the outer diameter of the screen cylinder is smaller than the diameter of the upper accommodating groove.

[0009] Optimally, the glue feeding unit includes a glue feeding groove opened on one side of the sleeve, and a first transition groove and a second transition groove opened obliquely in the sleeve and used to connect the glue feeding groove and the upper accommodating groove.

[0010] Optimally, the debonding unit includes a transfer groove opened in the sleeve and connected to the upper accommodating groove, and a debonding groove opened on the other side of the sleeve and connected to the transfer groove.

[0011] Optimally, the sleeve mechanism further includes a first inner abutment groove opened at the top of the upper accommodating groove and a second inner abutment groove opened at the bottom of the upper accommodating groove, the transfer groove is connected to the first inner abutment groove, and the screen drum abuts against the first inner abutment groove.

[0012] Optimally, the pressure tube includes an inner pressure tube, a middle pressure tube integrally connected to the bottom of the inner pressure tube, and an outer pressure tube integrally connected to the bottom of the middle pressure tube, and the inner pressure tube abuts in the second inner pressure groove.

[0013] Optimally, the pressure tube further includes a lower accommodating groove opened at the top of the inner pressure tube, a spring groove opened in the outer pressure tube and connected to the lower accommodating groove, and a spring arranged in the spring groove, and the spring is pressed against the bottom of the screen cylinder.

[0014] Optimally, the sieve drum includes a sieve drum wall, a first sieve plate fixed on the top of the sieve drum wall, a second sieve plate fixed on the bottom of the sieve drum wall, side sieve holes arranged in a ring on the sieve drum wall, first sieve holes coaxially and evenly spaced on the first sieve plate, and second sieve holes coaxially and evenly spaced on the second sieve plate.

[0015] Optimally, it also includes a locking mechanism for locking the sleeve mechanism and the pressing mechanism, wherein the locking mechanism includes a first locking tube locked to the bottom of the sleeve and a second locking tube integrally connected to the bottom of the first locking tube, and the second locking tube presses against the side of the middle pressing tube away from the inner pressing tube.

[0016] Optimally, the first transition groove and the second transition groove are coaxially arranged, and the diameter of the first transition groove is smaller than the diameter of the second transition groove.

[0017] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0018] The utility model discloses a flocking glue liquid filtering component. The glue liquid to be filtered is introduced into the glue inlet groove, flows into the gap between the screen drum and the upper accommodating groove, performs preliminary filtration and secondary filtration on the glue liquid through the screen drum, and finally is discharged from the glue discharge groove through the transfer groove on the top of the screen drum. The particle impurities are blocked by the screen drum in the gap between the screen drum and the upper accommodating groove and in the screen drum. The whole filtering component has a compact structure. The glue liquid is filtered twice, so the filtering effect is better and the purity of the glue liquid after filtration is higher. In addition, the subsequent cleaning of the screen drum is more convenient.

[0019] Furthermore, the arrangement of the inner and outer sealing rings can improve the sealing performance of the overall structure and prevent leakage of the glue;

[0020] Furthermore, the setting of the spring can not only press the screen drum tightly, but also facilitate the ejection of the pressing tube under the reverse force of the spring when the screen drum is replaced, thereby facilitating the replacement of the screen drum.

[0029] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0030] like Figure 1-4 The figure shows a cross-sectional view of the flocking glue liquid filter assembly of the present invention, which is used to filter the glue liquid to remove impurities and particles contained in the glue liquid, thereby improving the purity of the glue liquid. The filter assembly includes a sleeve mechanism, a pressing mechanism and a locking mechanism.

[0031] The pressing mechanism and the sleeve mechanism abut against each other. The glue to be filtered enters from one side of the sleeve mechanism, is filtered by the sieve drum inside the pressing mechanism, and is discharged from the other side of the sleeve mechanism. The locking mechanism locks between the pressing mechanism and the sleeve mechanism to lock the pressing mechanism and the sleeve mechanism. During the locking process, the internal sieve drum is pressed against each other, improving the glue filtration effect. At the same time, the sieve drum can be replaced after removing the locking mechanism.

[0032] like Figure 4 As shown, the casing mechanism includes a casing 1, a glue inlet groove 2, a first transition groove 3, a second transition groove 4, a first inner abutment groove 5, an upper accommodating groove 6, a second inner abutment groove 7, a transfer groove 8, a glue discharge groove 9, an outer abutment groove 10, and a first sealing groove 11. The upper accommodating groove 6 is provided at the bottom of the casing 1 to accommodate the sieve drum, and a gap is left between the upper accommodating groove 6 and the sieve drum to facilitate the sieve drum to filter the glue liquid.

[0033] The glue feed trough 2 is located on one side of the casing 1. A first transition trough 3 and a second transition trough 4 are obliquely disposed within the casing 1 and connect the glue feed trough 2 with the upper receiving tank 6. The first transition trough 3 and the second transition trough 4 are coaxially arranged, and the diameter of the first transition trough 3 is smaller than that of the second transition trough 4. The glue to be filtered is injected from the glue feed trough 2, passes through the first and second transition troughs 3 and 4, and flows into the upper receiving tank 6, where it is filtered by the sieve drum.

[0034] The diameter of the first transition trough 3 is smaller than that of the second transition trough 4 , so that the impact of the glue on the sieve drum can be reduced when the glue flows toward the sieve drum.

[0035] The first inner abutment groove 5 is opened at the top of the upper accommodating groove 6, and the diameter of the first inner abutment groove 5 is smaller than the diameter of the upper accommodating groove 6. The sieve drum abuts against the first inner abutment groove 5, so there is a gap between the sieve drum and the upper accommodating groove 6. The glue liquid to be filtered enters from the glue inlet groove 2, flows into the gap between the sieve drum and the upper accommodating groove 6, and then completes the filtration of the glue liquid through the sieve drum.

[0036] The second inner abutment groove 7 is opened at the bottom of the upper accommodating groove 6, and the diameter of the second inner abutment groove 7 is larger than the diameter of the upper accommodating groove 6. When the pressing mechanism is installed, the inner abutment tube 12 of the pressing mechanism is pressed against the second inner abutment groove 7, and an inner sealing ring 21 is provided between the inner abutment tube 12 and the second inner abutment groove 7 to seal the gap between the two to prevent leakage of the glue.

[0037] The transfer trough 8 is opened at the top of the first inner groove 5, and the glue discharge trough 9 is opened on the other side of the sleeve 1 and is connected to the transfer trough 8. The glue to be filtered is introduced into the glue inlet trough 2 and flows into the gap between the screen cylinder and the upper receiving tank 6. Then, after being filtered by the screen cylinder, it enters the transfer trough 8 on the top of the screen cylinder and is finally discharged from the glue discharge trough 9, while the impurity particles are blocked by the screen cylinder in the gap between the screen cylinder and the upper receiving tank 6.

[0038] The pressing mechanism abuts the bottom of the sleeve 1 and is used to filter the glue liquid, remove impurities and particulate matter contained in the glue liquid, and thus improve the purity of the glue liquid. The pressing mechanism includes an inner push tube 12, a middle push tube 13, an outer push tube 14, a spring groove 16, a spring 17, a second sealing groove 18, an outer sealing ring 19, a lower accommodating groove 20, an inner sealing ring 21, and a sieve. The middle push tube 13 is integrally connected to the bottom of the inner push tube 12, and the outer diameter of the middle push tube 13 is larger than the outer diameter of the inner push tube 12. Therefore, after the pressing tube abuts the bottom of the sleeve 1, the inner push tube 12 abuts in the second inner push groove 7, and the middle push tube 13 abuts the bottom of the sleeve 1.

[0039] like Figure 5 As shown, the sleeve 1 and the middle tube 13 are provided with a first sealing groove 11 and a second sealing groove 18 on the opposite sides thereof, and an outer sealing ring 19 is filled in the first sealing groove 11 and the second sealing groove 18. When the sleeve 1 and the middle tube 13 are in contact with each other, the outer sealing ring 19 is deformed to improve the sealing ability between the two and avoid leakage of the glue.

[0040] The outer abutment tube 14 is integrally connected to the bottom of the middle abutment tube 13, and the outer diameter of the outer abutment tube 14 is smaller than the outer diameter of the middle abutment tube 13. When the locking mechanism is in the locking sleeve mechanism and the pressing mechanism, the second locking tube 23 of the locking mechanism will abut against the side of the middle abutment tube 13 away from the inner abutment tube 12, thereby realizing the abutment between the pressing mechanism and the sleeve mechanism.

[0041] The lower accommodating groove 20 is opened at the top of the inner tube 12 and has the same diameter as the upper accommodating groove 6. By setting the lower accommodating groove 20, the filtering area of the screen drum can be increased, so that the glue can be filtered not only from the side wall of the screen drum, but also from the bottom of the screen drum, shortening the filtration time and improving the filtration efficiency.

[0042] The spring groove 16 is opened in the outer abutment tube 14 and is connected to the lower accommodating groove 20. The spring 17 is arranged in the spring groove 16 and abuts against the bottom of the screen cylinder. When the locking mechanism locks the sleeve mechanism and the pressing mechanism, the spring 17 is deformed and abuts against the bottom of the screen cylinder, and the screen cylinder abuts against the first inner abutment groove 5.

[0043] Under the action of the spring 17, the sieve cylinder is pressed against the first inner abutting groove 5, and the sieve cylinder is in close contact with the first inner abutting groove 5, so as to prevent the glue from leaking directly from the gap between the sieve cylinder and the first inner abutting groove 5; at the same time, when replacing the sieve cylinder, under the reverse force of the spring 17, the pressing tube is easily ejected, thereby facilitating the replacement of the sieve cylinder.

[0044] The sieve cylinder is set in the upper accommodating tank 6 and the lower accommodating tank 20, and the outer diameter of the sieve cylinder is smaller than the diameter of the upper accommodating tank 6. The glue to be filtered enters from the glue inlet tank 2, flows into the gap between the sieve cylinder and the upper accommodating tank 6, and then filters the glue through the side wall and bottom of the sieve cylinder. Figure 6As shown, the sieve drum includes a sieve drum wall 24 , a first sieve plate 25 , a second sieve plate 26 , a first sieve hole 27 , a second sieve hole 28 , a side sieve hole 29 and a limiting groove 30 .

[0045] The sieve wall 24 is cylindrical, the first sieve plate 25 is fixed on the top of the sieve wall 24 , and the second sieve plate 26 is fixed on the bottom of the sieve wall 24 , so that the sieve wall 24 , the first sieve plate 25 and the second sieve plate 26 form a hollow cylindrical structure.

[0046] Side sieve holes 29 are arranged around the circumference of the sieve drum wall 24. First sieve holes 27 are coaxially and evenly spaced within the first sieve plate 25, and second sieve holes 28 are coaxially and evenly spaced within the second sieve plate 26. The diameter of the side sieve holes 29 is equal to the diameter of the second sieve holes 28. The glue to be filtered enters the glue feed tank 2, flows into the gap between the sieve drum and the upper accommodating tank 6, and then passes through the side sieve holes 29 and the second sieve holes 28 to complete the initial filtration of the glue.

[0047] The initially filtered glue liquid enters the interior of the sieve drum wall 24 and then flows from the first sieve hole 27 to the transfer tank 8, wherein the diameter of the first sieve hole 27 is smaller than the diameter of the second sieve hole 28. The initially filtered glue liquid is subjected to secondary filtration through the first sieve hole 27 to improve the purity of the glue liquid after filtration.

[0048] The limiting groove 30 is provided at the bottom of the second sieve plate 26 , and the spring 17 is pressed against the limiting groove 30 . When the spring 17 is deformed and pressed against the sieve drum, the limiting action of the limiting groove 30 prevents the spring 17 from deflecting.

[0049] The locking mechanism is locked between the pressing mechanism and the sleeve mechanism to lock the pressing mechanism and the sleeve mechanism. During the locking process, the internal screen cylinder is pressed tightly to improve the effect of glue filtration. At the same time, the locking mechanism can be removed to replace the screen cylinder. The locking mechanism includes a first locking tube 22 and a second locking tube 23.

[0050] The first locking tube 22 is connected to the sleeve 1 via a threaded fit, and the second locking tube 23 is integrally connected to the bottom of the first locking tube 22. The inner diameter of the second locking tube 23 is smaller than that of the first locking tube 22. When the locking mechanism is locked with the sleeve mechanism and the pressing mechanism, the second locking tube 23 of the locking mechanism will abut against the side of the middle abutment tube 13 away from the inner abutment tube 12, thereby achieving abutment between the pressing mechanism and the sleeve mechanism.

[0051] When the screen drum needs to be replaced, the locking mechanism is unscrewed, and the push tube is ejected under the reverse force of the spring 17, and the internal screen drum is removed and flushed with water in reverse to flush out the particles filtered twice inside the screen drum.

[0052] When filtering the glue liquid, since the glue liquid has a certain viscosity, it is easy to cool down during the filtration process, resulting in clogging of the filter holes or poor fluidity. Therefore, when the glue liquid is introduced into the glue inlet groove 2, the locking mechanism and the pressing mechanism are placed in hot water or the heating wire. The temperature of the hot water or the heating wire is used to ensure the fluidity of the internal glue liquid, avoid cooling of the glue liquid, and thus improve the filtering effect of the glue liquid.

[0053] The filtering principle of the utility model flocking glue liquid filtering component is as follows:

[0054] The glue to be filtered is introduced into the glue inlet trough 2 and flows into the gap between the screen drum and the upper receiving tank 6. The glue is initially filtered and then filtered twice by the screen drum. Finally, it passes through the transfer trough 8 on the top of the screen drum and is discharged from the glue discharge trough 9. The particulate impurities are blocked by the screen drum in the gap between the screen drum and the upper receiving tank 6 and in the screen drum.

[0055] When the screen drum needs to be replaced, the locking mechanism is unscrewed, and the push tube is ejected under the reverse force of the spring 17, and the internal screen drum is removed and flushed with water in reverse to flush out the particles filtered twice inside the screen drum.
