Description

Technical Field

[0001] This utility model relates to the field of special material processing technology, and in particular to a glue cylinder assembly, a glue dispensing system, and a butyl rubber extruder. Background Technology

[0002] A butyl rubber machine is a specialized piece of equipment used to process butyl rubber. Through processes such as hot melting, extrusion, coating, or filling, butyl rubber is processed into various sealing products. Due to its excellent airtightness, weather resistance, and chemical stability, butyl rubber has become an ideal sealing material for industries such as construction, automotive, and electronics.

[0003] The butyl rubber coating machine is a key piece of equipment in the production of insulating glass. Its core function is to evenly coat both sides of the aluminum spacer frame with hot-melt butyl rubber, forming the first sealing barrier of the insulating glass. The butyl rubber coating machine's dispensing system is responsible for heating, pressurizing, and extruding the butyl rubber. The dispensing system mainly includes a dispensing cylinder assembly and a pressurizing system. The butyl rubber is fed into the dispensing cylinder assembly, and the pressurizing system forces the hot-melt butyl rubber out of the dispensing cylinder assembly to the coating mechanism, achieving quantitative extrusion.

[0004] The glue cylinder assembly includes a pressure plate and a cylinder. Butyl rubber is extruded from the pressure plate. A tight seal is required between the pressure plate and the cylinder; otherwise, the pressurization effect of the pressurization system will be affected. A common sealing method is to create a groove in the pressure plate and fit a sealing ring. The sealing ring, protruding from the outer circumference of the pressure plate, achieves a seal with the inner wall of the cylinder. However, during the use of the butyl rubber coating machine, the pressure plate and cylinder need to be frequently disassembled to clean residual glue. The disassembly and reassembly process causes relative movement between the sealing ring and the inner wall of the cylinder, leading to wear and frequent damage to the sealing ring. This results in glue leakage and pressure drop in the glue cylinder assembly, causing uncontrollable production efficiency, production costs, and product quality. Frequent replacements are necessary, increasing costs. Utility Model Content

[0005] The main purpose of this utility model is to provide a glue cylinder assembly that ensures stable sealing and controls production costs.

[0006] To achieve the above objectives, the glue cylinder assembly proposed in this utility model includes: A pressure plate, the outer wall of which has a sealing section, the sealing section gradually increasing in radius from one end of the pressure plate away from that end; and A cylinder is connected to the pressure plate and has a sealed inner wall section. The sealed inner wall section is located at one end of the cylinder and its inner diameter gradually decreases in the direction away from the pressure plate. The sealed inner wall section is sealed to the sealing section.

[0007] In one embodiment, a portion of the outer peripheral wall of the pressure plate has the sealing section.

[0008] In one embodiment, the pressure plate and / or the cylinder is made of brass.

[0009] In one embodiment, the pressure plate has extrusion holes, and the glue cylinder assembly further includes a filter screen.

[0011] In one embodiment, the glue cylinder assembly further includes a temperature sensor, and the pressure plate has a mounting hole; The temperature sensor is installed in the mounting hole and is used to monitor the material temperature inside the glue cylinder assembly.

[0012] In one embodiment, the pressure plate further has a vent hole that extends through the pressure plate along its thickness direction.

[0013] This utility model also proposes a glue application system, the glue application system comprising: A frame having a mounting plate having an adhesive outlet hole extending through the mounting plate along its thickness direction; The glue cylinder assembly has a pressure plate whose outer end abuts against the mounting plate. The pressure plate has an extrusion hole that is directly opposite the glue outlet hole. A booster system having a piston end that is movably disposed within the cylinder of the rubber cylinder assembly and is sealed to the inner wall of the cylinder.

[0014] In one embodiment, the diameter of the dispensing orifice is smaller than the diameter of the extrusion orifice.

[0016] In the technical solution of this utility model, the radius of the sealing section facing the cylinder gradually decreases to form the sealing section, and the inner diameter of the cylinder gradually decreases in the direction away from the pressure plate to form the sealing inner wall section. The sealing is achieved by the precise fit between the inclined surface formed by the sealing section and the sealing inner wall section, without relying on easily worn sealing rings.

[0024] This utility model proposes a glue cylinder assembly 200. Figures 1 to 2 This is one embodiment of the present utility model.

[0025] In this embodiment of the present invention, the glue cylinder assembly 200 includes a pressure plate 1 and a cylinder 2. The outer wall of the pressure plate 1 has a sealing section 11. The radius of the sealing section 11 gradually increases from one end of the pressure plate 1 in a direction away from that end. The cylinder 2 is connected to the pressure plate 1 and has a sealing inner wall section. The sealing inner wall section is located at one end of the cylinder 2 and its inner diameter gradually decreases in the direction away from the pressure plate 1. The sealing inner wall section is sealed to the sealing section 11.

[0026] In the technical solution of this utility model, the radius of the sealing section 11 facing the cylinder 2 gradually decreases to form the sealing section 11, and the inner diameter of the cylinder 2 gradually decreases in the direction away from the pressure plate 1 to form the sealing inner wall section. The sealing is achieved by the precise cooperation of the inclined surface formed by the sealing section 11 and the sealing inner wall section, without relying on the easily worn sealing ring, fundamentally avoiding the problem of frictional wear of the sealing ring during disassembly and assembly, effectively preventing glue leakage and pressure drop, ensuring the stable sealing of the glue cylinder assembly 200, and controlling production costs.

[0027] In one embodiment, a portion of the outer peripheral wall of the pressure plate 1 has the sealing section 11. By providing the sealing section 11 only on a portion of the outer peripheral wall of the pressure plate 1, specifically near one end of the cylinder 2, rather than machining the entire section, the manufacturing process of the pressure plate 1 can be simplified while ensuring reliable sealing. This reduces unnecessary machining area and lowers the manufacturing difficulty and production cost of the pressure plate 1. On the other hand, if the sealing section 11 of the pressure plate 1 is the entire outer peripheral wall of the pressure plate 1, then the inner wall of the cylinder 2 must be machined to fit the pressure plate 1, further increasing production costs. Since the wall thickness of the cylinder 2 is limited, excessive machining to form the sealing inner wall section would severely affect the strength of the corresponding position of the cylinder 2, resulting in a net loss.

[0028] In one embodiment, the pressure plate 1 and / or the cylinder 2 are made of brass. Brass has good wear resistance and thermal conductivity. Using brass as the material for the pressure plate 1 and the cylinder 2 can reduce wear during relative movement, extend the service life of the glue cylinder assembly 200, and ensure more uniform heat transfer of the hot-melt butyl rubber, ensuring the rubber compound remains in a stable hot-melt state, adapting to the working temperature environment of the butyl rubber coating machine, and guaranteeing processing stability. Using brass for either the pressure plate 1 or the cylinder 2 can achieve a certain degree of friction reduction. To minimize frictional wear between the pressure plate 1 and the cylinder 2, in this embodiment, both the pressure plate 1 and the cylinder 2 are made of brass.

[0029] In one embodiment, the pressure plate 1 has an extrusion hole 12, and the glue cylinder assembly 200 further includes a filter screen. The extrusion hole 12 extends through the pressure plate 1 along its thickness direction, and the filter screen is located within the glue cylinder assembly 200 and covers the extrusion hole 12. The pressure plate 1 has the extrusion hole 12 extending along its thickness direction for glue dispensing. The filter screen is disposed inside the extrusion hole 12 to filter impurities from the butyl glue to be extruded, preventing impurities from clogging the subsequent glue coating mechanism, ensuring smooth glue dispensing, and improving the purity of the butyl glue to further ensure the sealing quality of the first seal of the insulating glass.

[0030] In one embodiment, the pressure plate 1 has a mounting groove 13, and the extrusion hole 12 penetrates part of the bottom of the mounting groove 13. The filter screen is fixedly installed within the mounting groove 13. The mounting groove 13 provides a stable mounting reference and fixed space for the filter screen, and the groove wall of the mounting groove 13 can limit and ensure that the filter screen does not shift during the extrusion of the adhesive. Furthermore, the mounting groove 13 facilitates the disassembly and assembly of the filter screen, making subsequent cleaning, maintenance, and replacement convenient.

[0031] In one embodiment, the glue cylinder assembly 200 further includes a temperature sensor. The pressure plate 1 has a mounting hole 14, and the temperature sensor is installed in the mounting hole 14 to monitor the material temperature within the glue cylinder assembly 200. The mounting hole 14 on the pressure plate 1 allows for the installation of the temperature sensor, which can monitor the temperature of the butyl rubber within the glue cylinder assembly 200 in real time. This provides accurate temperature feedback to the heating system, ensuring that the rubber temperature is always controlled within a suitable hot melt range. This prevents the rubber from deteriorating due to excessively high temperatures or affecting its flowability due to excessively low temperatures, thus ensuring stable coating results. Furthermore, the mounting hole 14 provides a limit and support for the temperature sensor, preventing it from moving during the flow of the glue and thus preventing damage or blockage of the glue outlet.

[0032] In one embodiment, the pressure plate 1 further has a vent 15, which penetrates the pressure plate 1 along its thickness direction. The vent 15 can promptly discharge residual air within the glue cylinder assembly 200, preventing air from mixing into the butyl rubber and forming bubbles, which would severely affect the airtightness of the sealed product. Simultaneously, the vent 15 can eliminate interference from air inside the cylinder on the pressurization system, ensuring a stable pressurization process and guaranteeing the accuracy of the quantitative extrusion of butyl rubber.

[0033] This utility model also proposes a glue application system 1000, such as Figure 3 As shown, the glue dispensing system 1000 includes a frame 100, a glue cylinder assembly 200, and a pressurizing system. The frame 100 has a mounting plate 101, which has a glue outlet hole 102 extending through the mounting plate 101 along its thickness direction. The outer end of the pressure plate 1 of the glue cylinder assembly 200 abuts against the mounting plate 101. The pressure plate 1 has an extrusion hole 12, which is directly opposite to the glue outlet hole 102. The pressurizing system has a piston end, which is movably disposed within the cylinder 2 of the glue cylinder assembly 200 and is sealed to the inner wall of the cylinder 2. The outer end of the pressure plate 1 is tightly abutted against the mounting plate 101, and the extrusion hole 12 of the pressure plate 1 is precisely aligned with the glue outlet hole 102 of the mounting plate 101, ensuring a smooth glue delivery path. The piston end of the pressurization system is movably located inside the cylinder 2 and is sealed to the inner wall of the cylinder 2, providing stable extrusion pressure to extrude hot melt butyl rubber as required. The overall structure is compact and reliably sealed, meeting the core requirements of the glue dispensing system 1000 such as heating, pressurization, and extrusion. There is no loss due to the replacement of sealing rings during production, resulting in good economic benefits.

[0034] In one embodiment, the diameter of the dispensing orifice 102 is smaller than that of the extrusion orifice 12. When butyl rubber is discharged from the extrusion orifice 12 and enters the smaller-diameter dispensing orifice 102, a certain pressure buildup will form. This pressure increase can make subsequent dispensing more stable and uniform. When the dispensing orifice 102 cooperates with the coating mechanism, the accuracy of the quantitative output of butyl rubber can be further improved, and the fluctuation of dispensing amount can be avoided from affecting the coating quality.

[0035] Since the glue dispensing system 1000 includes the glue cylinder assembly 200, it also includes all the technical solutions of all the above embodiments of the glue cylinder assembly 200. Therefore, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0036] This utility model also proposes a butyl rubber coating machine, which includes a dispensing system 1000, a heating system, and a coating system. The heating system is connected to the dispensing system 1000 and is used to heat the butyl rubber material in the glue cylinder. The coating system is connected to the dispensing system 1000 and can quantitatively output the butyl rubber material. The heating system, the dispensing system 1000, and the coating system form a complete processing flow. The heating system provides a stable heat source for the butyl rubber in the cylinder 2, ensuring that the rubber reaches a suitable hot melt state. The dispensing system 1000, with its optimized sealing structure and functions such as impurity filtration and temperature monitoring, achieves stable pressurization and clean delivery of the rubber. The coating system finally completes the quantitative output and uniform coating of the butyl rubber. The entire system works in synergy, effectively solving the problems of rapid wear of sealing rings, leakage and pressure drop, and high cost of traditional equipment, while improving production efficiency and making product quality more controllable.

[0037] The specific structure of the glue application system 1000 is as described in the above embodiments. Since this butyl rubber coating machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
