Description

Technical Field

[0001] This application relates to the field of production equipment technology, and in particular to a rubber bucket and filter rod forming machine unit. Background Technology

[0002] The cold glue used in cigarette filter rods refers to the adhesive used during filter rod molding that operates at room temperature. It generally includes overlap cold glue and centerline cold glue. Overlap cold glue works in conjunction with hot melt adhesive to bond the two edges of the filter rod forming paper together, forming a complete cylindrical surface. Centerline cold glue is used to fix the fiber bundles inside the filter rod to the forming paper, preventing relative slippage. Because cold glue has high viscosity and operates at a low temperature, air bubbles trapped inside are often difficult to remove. Air bubbles in the cold glue can cause discontinuities in the glue line, leading to quality defects such as bursting, flash, and fiber slippage. Furthermore, because the location of the cold glue is relatively hidden, defects caused by cold glue are often discovered after a significant amount of product and raw materials have already been wasted.

[0003] In related technologies, air bubbles in cold glue can be removed by methods such as settling or heating before use. However, during the filling process of the filter rod forming unit, air bubbles may be introduced again due to foreign objects in the glue tank. These air bubbles may not have enough time to settle and dissipate naturally before entering the glue gun. Utility Model Content

[0004] Therefore, it is necessary to provide a glue tank and filter rod forming unit that can effectively eliminate air bubbles in the internal cold glue to address the above problems.

[0017] In one embodiment, the glue bucket further includes a pressure gauge disposed on the bucket body and used to detect the air pressure inside the receiving cavity.

[0018] In one embodiment, the glue bucket further includes a pressure relief valve, which is located in the bucket body and communicates with the receiving cavity, and can operably connect the receiving cavity to the outside.

[0019] In one embodiment, the barrel body includes a barrel body, a barrel lid, and a sealing ring. The top of the barrel body has an opening, and the barrel lid is sealed to the opening by the sealing ring. The barrel lid and the barrel body together enclose the receiving cavity.

[0020] The bucket body also includes a locking buckle, through which the bucket lid is detachably connected to the bucket body.

[0021] A filter rod forming unit includes the aforementioned rubber barrel.

[0022] The aforementioned glue bucket and filter rod forming unit can utilize a vacuum generator to create negative pressure within the containment cavity, accelerating the escape of air bubbles from the cold glue.

In this way, the glue bucket can effectively eliminate air bubbles in its internal cold glue, improving downstream production efficiency. Attached Figure Description

[0038] Please see Figures 1 to 3 An embodiment of this application provides a glue container 100, including a container body 10, a vacuum generating device 20, and a de-bubble remover 31. The container body 10 has a receiving cavity 11 and a glue outlet, the glue outlet being connected to the receiving cavity 11. The vacuum generating device 20 is connected to the receiving cavity 11. The de-bubble remover 31 is disposed on the container body 10 and located at the glue outlet.

[0039] In one embodiment, the glue tank 100 can be used in a filter rod forming unit. The receiving cavity 11 inside the tank body 10 can be used to hold cold glue, and the glue outlet is used to output cold glue to the glue gun of the filter rod forming unit. Specifically, the glue tank 100 can use the original glue supply system of the filter rod forming unit to supply cold glue.

[0040] Understandably, when the vacuum generating device 20 is working, it can create a negative pressure in the receiving cavity 11 inside the barrel 10. To avoid the intake of cold glue or blockage by cold glue, the connection between the vacuum generating device 20 and the barrel 10 is located at the upper part or top of the barrel 10, above the surface of the cold glue. Specifically, the vacuum generating device 20 can be located at the top of the barrel 10 and connected to the receiving cavity 11 through the top of the barrel 10.

[0041] The number of defoamers 31 can be one or more. Each defoamer 31 has a defoaming end. When air bubbles in the cold glue flow through the defoamer 31, the defoamer 31 can break the surface tension of the air bubbles, causing the air bubbles to break and float out.

[0042] The aforementioned glue bucket 100 can utilize the vacuum generator 20 to create negative pressure within the receiving cavity 11, accelerating the escape of air bubbles from the cold glue. Furthermore, the bubble-removing device 31 can break up air bubbles flowing outwards from the glue outlet, causing them to dissolve and float to the surface. Thus, the glue bucket 100 can effectively eliminate air bubbles in its internal cold glue, improving downstream production efficiency.

[0043] Furthermore, the barrel body 10 includes a barrel body 13, a barrel lid 15, and a sealing ring. The top of the barrel body 13 has an opening, and the barrel lid 15 is sealed to the opening by the sealing ring. The barrel lid 15 and the barrel body 13 together form a receiving cavity 11.

[0044] Specifically, the vacuum generating device 20 is located on the lid 15 and connects to the receiving cavity 11 through the lid 15. A sealing ring is located between the barrel body 13 and the lid 15 to enhance the sealing of the connection between the two.

[0045] Thus, the cold glue in the receiving cavity 11 can be injected by opening the bucket lid 15. The sealing ring between the bucket body 13 and the bucket lid 15 ensures the airtightness, so that the vacuum generating device 20 can form a negative pressure in the receiving cavity 11 formed by the two together.

[0046] Furthermore, the bucket body 10 also includes a locking buckle 80, through which the bucket lid 15 is detachably connected to the bucket body 13. In addition, the bucket lid 15 may also have an opening and closing port that can be opened separately.

[0047] In this way, the user can make the lid 15 and the body 13 form a stable connection by operating the locking buckle 80, and can also disconnect the lid 15 from the body 13 by operating the locking buckle 80 and remove the lid 15 for maintenance and repair.

[0048] In some embodiments, the glue tank 100 includes an outlet mesh 30 that covers the glue outlet. A defoamer 31 is provided on the outlet mesh 30, with its defoaming end located on the side of the outlet mesh 30 facing into the receiving cavity 11.

[0049] Specifically, the export mesh 30 can be, but is not limited to, a metal mesh, and specifically, a wire mesh woven from fine steel wires. At the junction of the wire mesh, a short steel wire is twisted and fixed to form two spikes in different directions. The structure obtained by twisting this short steel wire is the de-barbed 31.

[0050] In this way, the outlet net 30 can filter cold glue at the outlet and provide a basis for the installation of the de-bubble shaving 31, which can better break the air bubbles in the flowing cold glue at the outlet.

[0051] In some embodiments, the mesh size of the outlet mesh 30 is square or triangular.

[0052] Thus, the mesh shape of the export mesh 30 is square or triangular, which facilitates the passage of its angled boundaries and helps to eliminate air bubbles.

[0053] In some embodiments, the bubble 31 is located at the intersection of the mesh openings of the outlet mesh 30.

[0054] Understandably, the export net 30 has multiple mesh openings. In addition to the burr 31, which can be located at the intersection of some mesh openings or at the intersection of each mesh opening, the export net 30 has multiple mesh openings.

[0055] In this way, the defoamer 31 can be more stably fixed on the outlet mesh 30, and defoaming is performed on the cold glue passing through the mesh holes around it.

[0056] In some embodiments, the defoaming 31 has at least two defoaming ends, and at least a portion of the defoaming ends intersect with the orientation of the dispensing port.

[0057] Specifically, the defoaming puncture 31 is obtained by twisting and fixing a short steel wire, and the two ends of the short steel wire form two defoaming ends. The direction of the glue outlet can be vertical, and the angle between the defoaming end and the vertical direction can be, but is not limited to, 10°-20°, and can specifically be 10°, 12°, 15°, 17°, 20°, etc.

[0058] In this way, the bubble-piercing 31 can cover a larger area and penetrate deep into the cold glue through its surrounding mesh, breaking the air bubbles inside.

[0059] In other embodiments, the defoaming shavings 31 can also be manufactured by stamping, cutting, grinding, etc., and can also be integrally set with the outlet mesh 30. In addition, depending on the cold glue grade, viscosity, etc., the shape and aperture of the outlet mesh 30, as well as the height and inclination angle of the defoaming end of the defoaming shavings 31, can be adjusted. The outlet mesh 30 can also be a grid, etc., without specific limitations.

[0060] Please refer to the following: Figures 4 to 6 In some embodiments, the vacuum generating device 20 is a vacuum generator, which is connected to the receiving cavity 11 through its suction port 23.

[0061] Specifically, the vacuum generator is located on the lid 15 of the barrel 10, enabling it to create negative pressure in the receiving cavity 11 of the barrel 10 using compressed air, thereby accelerating the escape of air bubbles from the cold glue. Specifically, the vacuum generator has three interfaces: an air source interface 21, an intake interface 23, and an exhaust interface 25. When compressed air is introduced through the air source interface 21, negative pressure is generated at the intake interface 23. The air source interface 21 and exhaust interface 25 are arranged horizontally, while the intake interface 23 is vertically downward. The air source interface 21 can properly accommodate and position the nozzle of the compressed air gun 200 equipped next to each filter rod forming unit, allowing compressed air to be blown horizontally into the vacuum generator using the compressed air gun 200. The exhaust interface 25 is unobstructed and not aimed at personnel, materials, or precision parts of the equipment.

[0062] Thus, the vacuum generating device 20 of the glue barrel 100 can use the compressed air provided next to each filter rod forming unit to create negative pressure inside the glue barrel 100, and its own structure is simple and has little impact on the structure of the glue barrel 100 itself.

[0063] In some embodiments, the glue bucket 100 further includes a one-way valve 40, which is disposed between the vacuum generating device 20 and the bucket body 10 and connects the vacuum generating device 20 and the bucket body 10.

[0064] Specifically, the one-way valve 40 allows gas to flow from bottom to top, and the outlet above the one-way valve 40 is connected to the suction port 23 of the vacuum generator.

[0065] Thus, the one-way valve 40 helps improve the performance of the vacuum generator 20 and reduces the probability of external gas flowing back into the receiving cavity 11, causing an increase in air bubbles in the cold glue.

[0066] In some embodiments, the glue container 100 further includes a liquid blocking and venting component 50, which is disposed between the vacuum generating device 20 and the container body 10 and connects the vacuum generating device 20 and the container body 10.

[0067] Specifically, a hole is made on the upper surface of the lid 15 of the barrel body 10, and a liquid blocking and venting component 50 is connected by welding or flange gasket. The air outlet above the liquid blocking and venting component 50 is connected to the inlet below the one-way valve 40.

[0068] Thus, a liquid-blocking and venting component 50 is installed at the point where the barrel 10 leads to the one-way valve 40, which can prevent cold glue from overflowing and blocking the one-way valve 40 and the vacuum generator.

[0069] In some other embodiments, the vacuum generating device 20 may also be a vacuum pump, etc., which are not specifically limited here.

[0070] Please refer to the following: Figure 7In some embodiments, the glue container 100 further includes a pressure gauge 60, which is disposed on the container body 10 and used to detect the air pressure in the receiving cavity 11. Specifically, the pressure gauge 60 may be disposed on the container lid 15.

[0071] In this way, the user can observe the negative pressure value in the receiving cavity 11 through the pressure gauge 60. The maximum negative pressure red line can be marked on the pressure gauge 60 to prevent the vacuum in the receiving cavity 11 from being too high, causing the cold glue components to boil or affecting the normal operation of the glue pump.

[0072] In some embodiments, the glue bucket 100 further includes a pressure relief valve 70, which is disposed on the bucket body 10 and communicates with the receiving cavity 11, and can operably communicate the receiving cavity 11 with the outside.

[0073] Understandably, the pressure relief valve 70 is a vacuum pressure release valve, also known as a vacuum breaking valve. The pressure relief valve 70 is installed on the top or upper side of the barrel 10, and has a manual wrench or knob on the outside. The air outlet inside the pressure relief valve 70 should not be aimed at the cold glue or other valves and instruments, and the air inlet outside the pressure relief valve 70 should not be aimed at areas with a lot of material or dust.

[0074] In this way, the user can quickly depressurize the receiving cavity 11 through the pressure relief valve 70, so as to remove the bucket lid 15 and perform operations such as filling with cold glue.

[0075] To facilitate understanding of the solution in this application, the glue bucket 100 of this application will be described below using a specific embodiment as an example:

[0076] The glue bucket 100 includes a bucket body 10, a vacuum generator, a one-way valve 40, a liquid-blocking and venting device 50, a pressure gauge 60, a pressure relief valve 70, an outlet mesh 30 equipped with a bubble removal device 31, a sealing ring, a locking buckle 80, and other components.

[0077] A vacuum generator is mounted on the lid 15 of the barrel 10, enabling it to create negative pressure in the receiving cavity 11 of the barrel 10 using compressed air, thereby accelerating the escape of air bubbles from the cold glue. Specifically, the vacuum generator has three interfaces: an air source interface 21, an intake interface 23, and an exhaust interface 25. When compressed air is introduced through the air source interface 21, negative pressure is generated at the intake interface 23. The air source interface 21 and the exhaust interface 25 are arranged horizontally, while the intake interface 23 is vertically downward. The air source interface 21 can properly accommodate and position the nozzle of the compressed air gun 200 equipped next to each filter rod forming unit, so that compressed air can be blown horizontally into the vacuum generator using the compressed air gun 200. The exhaust interface 25 is unobstructed and should not be aimed at personnel, materials, or precision parts of equipment.

[0078] A one-way valve 40 is installed between the vacuum generator and the barrel 10. Sealing rings and locking buckles 80 are installed at the connection between the barrel body 13 and the lid 15 of the barrel 10 to ensure the sealing of the barrel 10. A liquid-blocking vent 50 is installed at the connection point between the barrel 10 and the one-way valve 40 to prevent cold glue from overflowing and blocking the one-way valve 40 and the vacuum generator. Specifically, an opening is made on the upper surface of the lid 15 of the barrel 10, and the liquid-blocking vent 50 is connected by welding or a flange gasket. The upper outlet of the liquid-blocking vent 50 is connected to the lower inlet of the one-way valve 40. The one-way valve 40 allows gas to flow from bottom to top, and the upper outlet of the one-way valve 40 is connected to the suction port 23 of the vacuum generator.

[0079] In addition, a pressure gauge 60 and a pressure relief valve 70 are installed on the barrel 10 for easy observation of the internal pressure and rapid pressure relief. An outlet mesh 30 is installed at the bottom of the barrel 10 at the glue outlet. The side of the outlet mesh 30 facing the receiving cavity 11 has debubbling punctures 31 to break the cold glue covering the surface of bubbles, disrupting the surface tension of the bubbles and causing them to break and float out. Specifically, the user can manually release the negative pressure in the receiving cavity 11 using the pressure relief valve 70, allowing outside air to enter the receiving cavity 11. The pressure relief valve 70 is installed on the top or upper side of the barrel 10 and has a manual wrench or knob on the outside. The air outlet inside the pressure relief valve 70 should not be aimed at the cold glue or other valves and instruments, and the air inlet outside the pressure relief valve 70 should not be aimed at areas with a lot of material or dust. The user can observe the negative pressure value in the receiving cavity 11 using the pressure gauge 60. The pressure gauge 60 can be marked with a maximum negative pressure red line to prevent excessive vacuum in the receiving cavity 11 from causing the cold glue components to boil or affecting the normal operation of the glue pump.

[0080] The outlet mesh 30 is woven from fine steel wire, with square or triangular holes. At the nodes of the wire mesh, a short piece of steel wire is twisted and fixed to form two spikes pointing in different directions, which serve as defoaming spikes 31. The wire mesh is horizontally fixed to the bottom of the barrel 10 and covers the bottom outlet. The defoaming ends of the defoaming spikes 31 face diagonally upwards, with an angle of 10°-20° between the defoaming ends and the vertical direction.

[0081] The aforementioned glue bucket 100, on the one hand, has a vacuum generator installed on its lid 15, enabling it to utilize the compressed air provided next to each unit to create negative pressure in the receiving cavity 11 within the bucket body 10, accelerating the escape of air bubbles from the cold glue. Simultaneously, the glue bucket 100 is also equipped with a one-way valve 40, a liquid-blocking and air-venting device 50, a pressure gauge 60, a pressure relief valve 70, a sealing ring, and a locking buckle 80, ensuring the stable and effective negative pressure within the receiving cavity 11. On the other hand, the bottom of the bucket body 10 has a glue outlet communicating with the receiving cavity 11, and a barbed wire mesh is installed at the outlet. The wire mesh is the outlet mesh 30, and the barbs are debubbling spikes 31. The debubbling spikes 31 can break the surface of air bubbles, causing them to break and float to the surface.

[0082] This application also provides a filter rod forming unit, including the aforementioned glue tank 100.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
