Description of the Invention: [Technical Field] The present invention relates to a multi-component dispensing device, and more particularly to a method of mixing a front tube head in one of a multi-component dispensing gun The integrator pin in the assembly. This application claims to be based on the US Provisional Application No. of "INTERNALLY MIXED POLYESTER FRONT HEAD" filed on September 13, 2010 by Richard D. Anderson, Steven R. Sinders and Jonathan R. McMichael, inventors of 35 USC §120. Priority is hereby incorporated by reference. [Prior Art] In an internal mixed multi-component dispensing gun, a resin and a catalyst are independently routed to a front tube assembly. In the front tube assembly, the resin and catalyst are mixed in a static mixer before being dispensed. Because the resin and the catalyst are substantially different liquids (e.g., they have significantly different viscosities), the static mixer must have many stages to mix the materials. This makes the length of the front tube assembly quite long and unsightly. In addition, after the user stops dispensing from the gun, the resin/catalyst mixture in the front tube head assembly has residual pressure that would continue to force the material out of the front tube head assembly against the wishes of the user. In addition, since the resin and the catalyst begin to react and harden after they are mixed, it is necessary to periodically rinse and/or clean the front tube head assembly after use of the front tube head assembly. SUMMARY OF THE INVENTION In one embodiment of the present invention, a front tube for a multi-component dispensing gun 158776.doc 201221227 head assembly includes a front tube body, a static mixer, and an integrator pin. . The front ferrule body has a plurality of ports at a rear end and a ferrule chamber extending to one of the front ends of the front ferrule body. The static mixer is positioned in the head cavity between the plurality of ports and the front end of the front head body. The integrator pin is positioned in the interior of the front body between the plurality of ports and the static mixer. In another embodiment, a front tube head for a multi-component dispensing gun includes a front tube body, a mixing chamber, a resin port, a catalyst port, a resin channel, and a catalyst channel. And an integrator pin. The front tube head has a rear end and a front end. The mixing chamber extends into the front end of the front head body and has a mixing tank at one of the rear ends of the mixing chamber and a mixing passage extending from the mixing tank to the front end of the front head body . The resin port and the catalyst port extend into the rear end of the front tube body. The resin channel fluidly connects the resin port to the mixing chamber, and the catalyst channel fluidly connects the catalyst port to the mixing chamber. The integrator pin is attached to the front body of the head at the rear end of the mixing chamber. The integrator pin has a wall extending into the mixing cell, wherein the integrator pin is positioned between the catalyst channel and the mixing channel. In another embodiment, an integrator pin for a multi-component dispensing gun includes a cylindrical base having a rounded surface and a cylindrical surface. Additionally, the integrator pin has a wall extending from the circular face and a projection of the wall extends substantially across the entire diameter of the circular face.

壁74(其延伸穿過混合池60且進入混合通道58)。整合器管 . 腳70係定位於觸媒通道66與樹脂通道68之間，使得觸媒通 道66係導引向壁74之内側76(顯示在圖4中）且樹脂通道68係 導引向壁74之外側78(顯示在圖4中）。另外，壁74係定位於 樹脂通道68與混合通道58之間。 氣帽34係附接至前管頭體38之前端。氣帽34使喷嘴32、 止回閥80及混合器外殼54保留在前管頭總成12中。氣帽34 具有氣孔90，其為導引向在噴嘴32(混合物係自前管頭總 成12之喷嘴32喷出）前之一區之一孔。氣孔90係藉由一空 氣通道（圖中未顯示）而流體連接至空氣端口 46(顯示在圖2 中），該空氣通道係流體連接至在管頭腔室52内但在混合 q 器外殼54外側之空間。在混合器外殼54前之各種位置處解 除混合器外殼54以允許空氣自管頭腔室52通至氣帽34。 止回閥80係在混合腔室56(及管頭腔室52)之前端處且在 ' 喷嘴32之後端處。更具體言之，止回閥80係定位在靜態混 - 合器62前之混合器外殼54之一加寬端内。止回閥80包含閥 座82、閥提升頭84、閥彈簧86及閥體88。通常，閥彈簧86 將作用力施加在閥體88及閥提升頭84上以迫使閥提升頭84 抵著閥座82。 圖3中亦顯示溶劑通道92。溶劑通道92將溶劑端口 44(顯 158776.doc -11 - 201221227 示在圖2中）與樹脂通道68流體連接。 當使用者扣動扳機1 8(顯示在圖1中）時，觸媒及樹脂分 別通過觸媒端口 4 0、觸媒通道6 6、樹脂端口 4 2、樹脂通道 68而向前流入至混合池60中。因為壁74實質上阻止樹脂進 入混合通道58，所以樹脂必須圍繞壁74之外側78(顯示在 圖4中）移動以到達混合池60之相對側，樹脂通道68自該側 橫穿混合池60。在所繪示實施例中，樹脂及觸媒被施予高 達約13.8兆帕（每平方英寸2000磅）之壓力，但正常工作壓 力約為6.89兆帕（每平方英寸1000磅）。當樹脂係圍繞整合 器管腳70而轉移時，其流實質上為紊流。因為觸媒通道66 係導引向混合通道58，所以觸媒具有至混合通道58之一更 加直接路徑。但因為樹脂之紊流使其路徑在通至混合通道 58時圍繞混合池60，所以其與觸媒部分混合以形成一混合 物。再者，圍繞混合池60之樹脂紊流與觸媒通道66之定向 結合導致觸媒進入由樹脂圍封或包圍之混合通道58。在所 繪示實施例中，混合物分別包括1 %至3%觸媒體積及99% 至97%樹脂體積。 使觸媒由樹脂包圍意謂當混合物最初進入混合通道5 8時 觸媒實質上在混合物之中心附近。混合物之管柱被分裂成 兩半且由第一混合元件64摺疊。當混合物到達第二混合元 件64時，垂直於最初裂缝而分裂混合物且再次摺疊混合 物。在各混合元件64處重複分裂及摺疊程序直至混合物到 達靜態混合器62之端部。在所繪示實施例中，靜態混合器 6 2中存在八個混合元件6 4。在混合物已流動通過靜態混合 158776.doc -12- 201221227 器62之後，混合物係足夠均質。 在靜態混合器62之後’混合物進入止回閥8〇。混合物施 加力抵著閥提升頭84以迫使閥提升頭84離開閥座82。在圍 繞閥提升頭84之外緣之各種位置處解除閥提升頭84以允許 混合物圍繞閥提升頭84流動且通過閥體88。在止回閥8〇之 後’混合物進入噴嘴32。當混合物自前管頭總成12流出 時’喷嘴3 2使混合物流定形。另外，在混合物已離開前管 頭總成12之後，來自氣孔90之空氣使混合物流定形。 當使用者放開扳機18(顯示在圖1中）時，觸媒及樹脂至 前管頭總成中之流動停止。觸媒及樹脂保留迫使前管頭總 成12中之混合物自喷嘴32流出之一些殘留壓力。但閥彈簧 86具有足夠力量以抵著此殘留壓力而關閉止回閥8〇。此防 止混合腔室56中之混合物在已放開扳機丨8之後自喷嘴32洩 漏。由此，在放開扳機i 8(顯示在圖1中）後被允許自前管頭 總成12流出之混合物僅少量含於閥體88及喷嘴32中。 若在混合物之凝膠時間（在所繪示實施例中為1〇分鐘）之 前將不使用施配槍1〇(顯示在圖1中），則建議使用者用溶劑 沖洗前管頭總成12。溶劑進入溶劑端口 44(顯示在圖2中）且 移動通過溶劑通道92而進入樹脂通道68。溶劑向前流動以 位移在其路徑上之任何樹脂、觸媒或混合物。在充分沖洗 之後’無混合物保留在前管頭總成12中。此為重要，因為 若混合物在足夠時間内不受擾動則混合物將硬化且堵塞前 管頭總成12。除沖洗程序以外或取代沖洗程序’前管頭總 成12可由使用者移除且被放置在用於清潔及/或儲存之一 158776.doc •13- 201221227 溶劑槽中。若前管頭總成12被移除，則可在清潔及/或儲 存原前管頭總成時於其位置上附接另一前管頭總成。 如圖3中所示’前管頭總成12之組件及組態允許樹脂及 觸媒被混合且自前管頭總成丨2被噴出。更具體言之，觸媒 係由樹脂圍封或包圍且在被靜態混合器62充分均質化之前 被預先混合。使觸媒最初實質上置於混合物之中心以當觸 媒及樹脂流動通過靜態混合器62時實質上防止觸媒沿樹脂 之邊流動（且非真正混合）。另外，當使用者期望停止混合 物之施配時，止回閥8〇防止混合物中之殘留壓力推動留在 刖官頭總成12中之混合物之大多數通過噴嘴32而流出。 圖3中描繪本發明之一實施例，存在該實施例之若干替 代實施例。例如，溶劑通道92可連接至樹脂端口 42。對於 另一貫例，可存在八個以上或八個以下混合元件64。對於 另一貫例’壁74可橫越混合池6〇而實質上延伸至混合通道 58。在此一實施例中，整合器管腳7〇不延伸至混合通道58 中 〇 圖4中顯示包含圓柱基座72及壁74之整合器管腳之一 側透視圖。圖4中顯示整合器管腳7〇、圓柱基座72、壁 74内側76外側78、圓柱面94、圓面96、直徑98及割線 100 ° 如前所述，整合器管腳70包括圓柱基座72及壁74。圓柱 基座72具有15繞圓柱基座72之圓周之圓柱面94及圓柱基座 72之一端部處之圓面96。圓面％具有延伸橫越圓面％之直 徑98 ^在與圓面96相對之圓柱基座72之一端部上圓柱基 158776.doc -14- 201221227 座72具有消除一銳緣之一倒角The solvent inlet of the gun 10 is directly in front of the 14C and is fluidly connected to the solvent 阙36 of the solvent inlet i4C. This allows pressurized solvent to flow through the dispensing gun and solvent outlet 26 to enter the front tube head assembly 12. The solvent forces the mixture out of the nozzle 32 to rinse the front tube assembly 12. As shown in Figure 1, the components and configuration of the snatch are allowed to mix and dispense the resin and catalyst in a controlled manner. In addition, the fastener 3 and the external thread 37 allow the front tube assembly 12 to be removed from the dispensing gun 10 to clean and/or replace the front tube assembly 12. A rear perspective view of the tube head assembly 12 prior to the catalyst port 4〇, the resin port 42 and the fastener 3〇 is shown in FIG. The front tube head assembly 12, the buckle member 30, the front tube body 38, the catalyst port 40, the resin port 42, the solvent port 44, the air port 46, the abutting texture 48, and the internal thread 5 are shown in FIG. As previously mentioned, the front tube head assembly 12 is detached from the front tube head assembly 12 by fasteners 3〇. More specifically, the fastener 3 is rotatably attached to the head body 38 prior to the front tube head assembly 12. The fastener 3 has an internal thread 50 that surrounds the interior of the fastener 3〇. In the illustrated embodiment, the internal thread 5 has a μ. Thread angle - The trapezoidal thread shape has a thread height that is approximately half the pitch height and the screw top and the screw bottom are flat. Because the inner screw is 5 inside the fastener, the current tube head assembly is attached to the inner thread 5 〇 and 158776.doc 201221227 thread 3 7 (shown in Figure 1) Connected. Additionally, the fastener 30 has a grip texture 48 that surrounds the exterior of the fastener 30. In the illustrated embodiment, the fastener 3 is embossed as a grip texture 48. The grip texture 48 allows the user to grip the fastener 30 to attach the front tube head assembly 12 to the dispensing grab 10 (shown in Figure 1) or from the dispensing gun 1 (shown in Figure 1). The front official head assembly turns the fastener 30 at 12 o'clock. Catalyst port 40, resin port 42, solvent port 44, and air port 46 are also attached to the rear of front head body 38. The catalyst port 40, the resin port 42, the solvent port 44, and the air port 46 all extend into the rear portion of the front tube body 38. When the current tube head assembly 12 is attached to the dispensing gun 1 (shown in Figure 10), the catalyst port 40 is fluidly connected to the catalyst outlet 22, and the resin port 42 is fluidly connected to the resin outlet 24, solvent port. The 44 series fluid is connected to the solvent outlet 26, and the air port 46 is fluidly connected to the air outlet 28. Thus, the catalyst port 4 is self-dispensing to receive 10 receiving catalyst, the resin port 42 is self-dispensing to receive 1 〇 receiving resin, the solvent port 44 is self-dispensing to receive 10 receiving solvent, and the air port is self-dispensing to grab 1 〇 Receive air. As shown in Figure 2, the components and configuration of the front tube head assembly 12 allows the front tube head assembly 12 to be attached to the dispensing 1 (shown in Figure... More specifically, the grip texture 48 and within The thread 5〇 allows the user to quickly attach or detach the front tube head assembly u without the mu's multiple ends σ4〇 to 46 allowing the front tube head assembly 12 to receive catalyst, resin, solvent and air. There are several alternative embodiments of this embodiment of the present invention. For example, the grip texture 48 can be a raised portion (as shown on the cap ring, shown in Figure Q), embossed, stippled, square Grid or some - other catch 158776.doc 201221227 Hold the reinforced shape and / or finish. For another example, the internal thread 5 〇 can be a thread. Figure 3 shows the integrator pin 7 〇 and the check valve 8 〇 A cross-sectional perspective view of one of the previous tube head assemblies 12. Figure 3 shows the front tube head assembly 12, fasteners 3, nozzle 32, air cap 34, cap ring %, front tube body 38, catalyst port 40, resin port 42, tube head chamber 52, mixer housing 54, mixing chamber 56, mixing passage 58, mixing tank 6 静态, static mixer 62, The clutch element 64, the catalyst channel 66, the resin channel 68, the integrator pin 70, the cylindrical base 72, the wall 74, the check valve 80, the valve seat 82, the valve lift head material, the valve body valve body 88, The vent 90 and the solvent passage 92. Generally, the front ferrule 38 includes a solid cylinder in or on which a variety of features are formed. For example, there is a shoulder 38S adjacent the rear end of the front ferrule 38. The fastener 30 is A ring and its own shoulder 3〇s (one of the rear ends of the fastener 3) corresponds to the shoulder 38S on the front tube body 38. More specifically, the hole is not larger than the shoulder of the head body 38. In addition to the portion 3 8 S, the aperture of the fastener 30 is greater than the width of one of the front tube heads 38. This provides a bearing surface on which the fastener 30 can act to attach to the front tube assembly 12 to the dispensing. The front tube body 38 is fastened when grabbing 10 (shown in Figure i). Further, when the cap ring 35 is attached to one of the threaded portions near the front end of one of the front tube heads 38, the fastener 3 is locked in For the other tube head 38. For another example, the catalyst port 40 and the resin port 42 are blind holes cut out from the rear of the front tube body 38. The mixing chamber is formed in the front tube The head body π starts at the front of the front tube body 38 and extends almost (but not completely) to the catalyst port 40 and the resin port 42. The catalyst port 4 and the resin port 42 are respectively through the catalyst channel 66 and Resin channel 68 is fluidly coupled to mixing chamber 56. 158776.doc 201221227 Channels 66 and 6 8 are angled forward and toward the center of front tube body 38. Specifically, channels 66 and 68 terminate in the mixing chamber One portion of 56 (i.e., mixing tank 60) is located. Mixing tank 60 is a shallow disc-shaped chamber, and the remainder of mixing chamber 56 (referred to as mixing passage 58) extends forward from the center of the chamber. The integrator pin 70 is positioned in the front tube body 38 on the side of the mixing cell 60 opposite the mixing channel 58. As described in greater detail below, the integrator pin 70 is configured such that it blocks resin flow from the resin channel 68 to the mixing channel 58 but hardly blocks the catalyst in the self-catalyst channel 66 to the mixing channel 58. Flow (if any). More specifically, in the illustrated embodiment, the ferrule chamber 52 extends rearward from the front end of the front ferrule body 38. The mixer housing 54 is positioned in the tube head chamber 52. The mixing chamber 56 extends through the mixer housing 54. The mixing chamber 56 includes a mixing passage 58 (which is the front of one of the mixing chambers 56) and a mixing tank 60 (which is the rear of one of the mixing chambers 56). Static mixer 62 is positioned in mixing channel 58. In the illustrated embodiment, static mixer 62 is comprised of a plurality of mixer elements 64. Each mixer element 64 has a thin rectangular shape that has been twisted by 90[deg.] along its longitudinal axis. Each mixer element 64 is oriented at 90° to the adjacent mixer element 64. This means that one of the leading edges of each of the mixer elements 64 is substantially perpendicular to one of the trailing edges of the previous mixing element 64 (if present), and the trailing edge of each of the mixer elements 64 is substantially perpendicular to the latter mixing element 64 (if present) ) One of the leading edges. As previously mentioned, the catalyst port 40 and the resin port 42 extend into the rear end of the front tube body 38. Catalyst channel 66 extends from catalyst port 40 forward to one of the rear ends of tube head chamber 52 to fluidly connect catalyst port 40 to mixing cell 60. Resin channel 68 extends forwardly from resin port 42 to the rear end of tube head chamber 52 to fluidly couple resin 158776.doc -10- 201221227 port 42 to mixing cell 60. The integrator pin 70 is attached to the front tube body 38 at the rear end of the mixing chamber 56 (which is also the rear end of the tube head chamber 52). In the illustrated embodiment, the integrator pin 70 includes a cylindrical base 72 (which is disposed into the front body 38) and a wall 74 (which extends through the mixing pool 60 and into the mixing passage 58). The integrator tube. The foot 70 is positioned between the catalyst channel 66 and the resin channel 68 such that the catalyst channel 66 is directed toward the inner side 76 of the wall 74 (shown in Figure 4) and the resin channel 68 is directed toward the wall. 74 outer side 78 (shown in Figure 4). Additionally, wall 74 is positioned between resin passage 68 and mixing passage 58. A gas cap 34 is attached to the front end of the front tube body 38. The gas cap 34 retains the nozzle 32, check valve 80, and mixer housing 54 in the front tube head assembly 12. The gas cap 34 has a vent 90 that is directed toward one of the areas in front of the nozzle 32 (the mixture is ejected from the nozzle 32 of the front ferrule assembly 12). The vent 90 is fluidly coupled to an air port 46 (shown in Figure 2) by an air passage (not shown) that is fluidly coupled within the plenum chamber 52 but in the hybrid q housing 54 The space outside. The mixer housing 54 is removed at various locations in front of the mixer housing 54 to allow air to pass from the tube head chamber 52 to the gas cap 34. Check valve 80 is at the front end of mixing chamber 56 (and head chamber 52) and at the rear end of 'nozzle 32. More specifically, the check valve 80 is positioned within one of the widened ends of the mixer housing 54 in front of the static mixer 62. The check valve 80 includes a valve seat 82, a valve lift head 84, a valve spring 86, and a valve body 88. Typically, valve spring 86 exerts a force on valve body 88 and valve lift head 84 to force valve lift head 84 against valve seat 82. Solvent channel 92 is also shown in FIG. Solvent channel 92 fluidly couples solvent port 44 (shown in Figure 2 to 158776.doc -11 - 201221227) to resin channel 68. When the user pulls the trigger 18 (shown in FIG. 1), the catalyst and the resin flow forward to the mixing pool through the catalyst port 40, the catalyst channel 66, the resin port 4, and the resin channel 68, respectively. 60 in. Because the wall 74 substantially prevents the resin from entering the mixing channel 58, the resin must move around the outer side 78 of the wall 74 (shown in Figure 4) to reach the opposite side of the mixing cell 60 from which the resin channel 68 traverses the mixing cell 60. In the illustrated embodiment, the resin and catalyst are subjected to a pressure of up to about 13.8 MPa (2,000 psi), but the normal working pressure is about 6.89 MPa (1000 psi). When the resin is transferred around the integrator pin 70, its flow is substantially turbulent. Since the catalyst channel 66 is directed toward the mixing channel 58, the catalyst has a more direct path to one of the mixing channels 58. However, because the turbulence of the resin causes its path to surround the mixing cell 60 as it passes to the mixing channel 58, it mixes with the catalyst portion to form a mixture. Moreover, the directional interaction of the resin turbulence around the mixing cell 60 with the catalyst channel 66 causes the catalyst to enter the mixing channel 58 enclosed or surrounded by the resin. In the illustrated embodiment, the mixture includes from 1% to 3% of the touch media product and from 99% to 97% resin volume, respectively. Surrounding the catalyst by the resin means that the catalyst is substantially near the center of the mixture as it initially enters the mixing channel 58. The column of the mixture is split into two halves and folded by the first mixing element 64. When the mixture reaches the second mixing element 64, the mixture is split perpendicular to the original crack and the mixture is again folded. The splitting and folding process is repeated at each mixing element 64 until the mixture reaches the end of the static mixer 62. In the illustrated embodiment, there are eight mixing elements 64 in the static mixer 62. After the mixture has flowed through static mixing 158776.doc -12- 201221227 62, the mixture is sufficiently homogeneous. After the static mixer 62, the mixture enters the check valve 8〇. The mixture exerts a force against the valve lift head 84 to force the valve lift head 84 away from the valve seat 82. The valve lift head 84 is released at various locations around the outer edge of the valve lift head 84 to allow the mixture to flow around the valve lift head 84 and through the valve body 88. The mixture enters the nozzle 32 after the check valve 8〇. When the mixture flows out of the front ferrule assembly 12, the nozzle 3 2 streams the mixture. Additionally, air from the vents 90 causes the mixture to flow after the mixture has exited the front tube assembly 12. When the user releases the trigger 18 (shown in Figure 1), the flow of catalyst and resin into the front tube head stops. Catalyst and resin retention forces some of the residual pressure from the nozzle 32 in the mixture of the front tube head assembly 12. However, the valve spring 86 has sufficient force to close the check valve 8 抵 against this residual pressure. This prevents the mixture in the mixing chamber 56 from leaking from the nozzle 32 after the trigger 丨 8 has been released. Thus, the mixture allowed to flow from the front ferrule assembly 12 after releasing the trigger i 8 (shown in Figure 1) is only contained in the valve body 88 and the nozzle 32 in a small amount. If the dispensing gun 1〇 (shown in Figure 1) will not be used before the gel time of the mixture (1 〇 in the illustrated embodiment), it is recommended that the user rinse the front tube assembly 12 with solvent. . The solvent enters solvent port 44 (shown in Figure 2) and moves through solvent channel 92 into resin channel 68. The solvent flows forward to displace any resin, catalyst or mixture in its path. After the sufficient rinsing, no mixture remains in the front ferrule assembly 12. This is important because if the mixture is not disturbed for a sufficient time, the mixture will harden and clog the front tube assembly 12. In addition to or in lieu of the rinsing procedure, the front ferrule assembly 12 can be removed by the user and placed in a solvent bath for cleaning and/or storage 158776.doc • 13-201221227. If the front ferrule assembly 12 is removed, another front ferrule assembly can be attached to its original position when cleaning and/or storing the original ferrule assembly. The assembly and configuration of the 'front tube head assembly 12' as shown in Figure 3 allows the resin and catalyst to be mixed and ejected from the front tube head assembly 丨2. More specifically, the catalyst is enclosed or surrounded by a resin and pre-mixed prior to being sufficiently homogenized by the static mixer 62. The catalyst is initially placed substantially at the center of the mixture to substantially prevent the catalyst from flowing along the sides of the resin (and not actually mixing) as the catalyst and resin flow through the static mixer 62. In addition, when the user desires to stop the dispensing of the mixture, the check valve 8 prevents the residual pressure in the mixture from pushing the majority of the mixture remaining in the stern head assembly 12 out through the nozzle 32. One embodiment of the invention is depicted in Figure 3, and there are several alternative embodiments of this embodiment. For example, solvent channel 92 can be coupled to resin port 42. For another consistent example, there may be more than eight or less than eight mixing elements 64. For another consistent example, the wall 74 can extend across the mixing cell 6 to substantially extend to the mixing channel 58. In this embodiment, the integrator pin 7 does not extend into the mixing channel 58. A side perspective view of the integrator pin including the cylindrical base 72 and the wall 74 is shown in FIG. 4 shows the integrator pin 7〇, the cylindrical base 72, the inner side 76 of the wall 74, the outer surface 78, the cylindrical surface 94, the circular surface 96, the diameter 98, and the secant 100°. As previously described, the integrator pin 70 includes a cylindrical base. Seat 72 and wall 74. The cylindrical base 72 has a cylindrical surface 94 around the circumference of the cylindrical base 72 and a circular surface 96 at one end of the cylindrical base 72. The round face % has a diameter 98 extending across the circumference of the circle. ^ On one end of the cylindrical base 72 opposite the circular face 96, the cylindrical base 158776.doc -14- 201221227 The seat 72 has a chamfer that eliminates one sharp edge.

(4) Included from the circle: the outer side 78 extends along the cylindrical surface 94. The wall 74 also includes an inner side 76 that is offset from the outer surface and substantially offset from the outer (four). The wall 74 is formed by generally forming a ^ e foot 70 ' by digging a hole in the center of the solid cylinder and by crossing the side of the cylinder to break into the = eight. More specifically, the wall edge (10) is the line along which the cut is made. This means that the wall 74 is substantially an arc having a substantially uniform radial thickness that occupies more than one hemisphere (18 Å.). The alcove occupies a circle of approximately ?% (216) ' because the wall edge 100 is offset from the diameter 98. Additionally, wall 74 extends substantially across the entire length of diameter 98, but the niche does not lie in the diameter (four) position. The outer end of the wall 74 is chamfered outward _, which eliminates - sharp edges. The configuration of the non-integrated pin 7 of Figure 4 allows for interruption of the flow from the resin channel 68 (shown in Figure 3) to the mixing, cell 6 (shown in Figure 3). In addition, the resin flow system I around the integrator pin 7G flows. In addition, the integrator pin 70 allows the catalyst to be inserted into the center of the resin stream, which helps to ensure that the mixture is sufficiently homogenized prior to being dispensed. In addition, the chamfered end of the integrator pin 7 允许 allows for easier fabrication and assembly of the front ferrule assembly 12 (shown in 囷^) because the chamfer eliminates potentially blunt edges. In Fig. 4, "one embodiment of the invention is depicted, and there are several alternative embodiments of this embodiment. For example, wall 74 may occupy more than 60% of the circle. For another example, wall 74 may occupy less than 60% of a circle. In this embodiment, the outer diameter and the wall edge 100 may be collinear. For another example, there may be two non-collinear wall edges 100. In this embodiment, the wall edge i 〇〇 may be parallel and perpendicular to 158776. .doc -15- 201221227 Diameter 98. For yet another example, wall 74 can extend substantially across the entire length of diameter 98 by traversing diameter 98. It will be appreciated that the present invention provides numerous benefits and advantages. For example, There are fewer mixer elements 64 in the static mixer 62 because the resin and catalyst are premixed and the catalyst is initially substantially near the center of the mixture. For another example, the front tube head assembly 12 can be fast, easy and The tool 10 is removed without the need for a tool. For another example, the front tube head assembly 12 does not leak a significant amount of the mixture after the user has released the trigger. Although reference has been made to one (several) illustrative embodiment Describe the invention, It will be appreciated by those skilled in the art that various changes may be made and equivalents may be substituted for the elements of the invention without departing from the scope of the invention. In addition, many modifications may be made without departing from the basic scope of the invention. A particular embodiment or material is suitable for use in the teachings of the present invention. It is therefore intended that the invention not be limited to the specific embodiments disclosed.
