[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0022] As Figures 1 to 4 shown, a double hydraulic screw dispenser includes a feeding device 1 and a double hydraulic screw assembly 2. The double hydraulic screw assembly 2 is connected to the feeding device 1. The feeding device 1 includes a first storage barrel 101 and a second storage barrel 102. A first feeding pipe 103 is connected below the first storage barrel 101. The first storage barrel 101 is connected to a first feeding cylinder 105 through the first feeding pipe 103. A second feeding pipe 104 is connected below the second storage barrel 102. The second storage barrel 102 is connected to a second feeding cylinder 106 through the second feeding pipe 104. A flow limiting valve body 107 is commonly connected below the first feeding cylinder 105 and the second feeding cylinder 106. A feeding block 108 is connected to the outlet of the flow limiting valve body 107. Since the flow limiting valve body 107 is connected below the first feeding cylinder 105 and the second feeding cylinder 106, when the glue in the first feeding cylinder 105 and the second feeding cylinder 106 is about to flow into the feeding block 108, the flow rate of the glue inside the first feeding cylinder 105 and the second feeding cylinder 106 is controlled by the flow limiting valve body 107. By controlling the flow rate of the colloid, the proportion control can be carried out during the subsequent mixing.

[0023] Further, the double hydraulic screw assembly 2 includes a first hydraulic screw 201 and a second hydraulic screw 202. A first material receiving chamber 203 is connected below the first hydraulic screw 201. A second material receiving chamber 204 is connected below the second hydraulic screw 202. A first material receiving port 205 is opened on the first material receiving chamber 203. A second material receiving port 206 is opened on the second material receiving chamber 204. A mixing chamber 207 is further connected below the first material receiving chamber 203 and the second material receiving chamber 204. A mixing pipe 208 is further connected below the mixing chamber 207. Among them, the feeding block 108 is communicated with the first material receiving port 205 and the second material receiving port 206, and the glue is conveyed into the first material receiving chamber 203 and the second material receiving chamber 204. Then, the first hydraulic screw 201 conveys the glue in the first material receiving chamber 203 into the mixing chamber 207, and the second hydraulic screw 202 conveys the glue in the second material receiving chamber 204 into the mixing chamber 207, and finally the mixing is completed.

[0024] Furthermore, the feeding device 1 further includes a glue discharging seat 110 and a fixed cover plate 109. A dispensing head 111 is arranged below the glue discharging seat 110. The mixing tube 208 is inserted into the interior of the glue discharging seat 110 and communicates with the dispensing head 111. The mixing tube 208 dispenses glue through the dispensing head 111. A scraper 3 is also connected to the dispensing head 111. The scraper 3 is detachably connected to the dispensing head 111. The scraper 3 is provided with a strip-shaped glue outlet which can change the shape of the glue discharge to make the dispensing machine have a wider application range. A slide rail 112 is installed on the feeding device 1. A slider 113 is also connected above the slide rail 112. The double hydraulic screw component 2 is installed on the slider 113. The double hydraulic screw component 2 is slidably connected to the slide rail 112 through the slider 113.

[0025] During use, first, the glue in the first storage barrel 101 flows into the first feeding cylinder 105 through the first feeding pipe 103, and the glue in the second storage barrel 102 flows into the second feeding cylinder 106 through the second feeding pipe 104. When the glue in the first feeding cylinder 105 and the second feeding cylinder 106 is about to flow into the feeding block 108, the flow rate of the glue inside the first feeding cylinder 105 and the second feeding cylinder 106 is controlled by the flow-limiting valve body 107. By controlling the flow rate of the colloid, the proportion control can be carried out during subsequent mixing. The glue in the feeding block 108 flows into the first receiving chamber 203 through the first receiving port 205 and into the second receiving chamber 204 through the second receiving port 206. Then, the first hydraulic screw 201 pushes the glue in the first receiving chamber 203 into the mixing chamber 207, and the second hydraulic screw 202 pushes the glue in the second receiving chamber 204 into the mixing chamber 207 to complete the final mixing. When the glue is mixed inside the mixing chamber 207, the glue inside the mixing chamber 207 enters the interior of the mixing tube 208, and the mixing tube 208 dispenses glue through the dispensing head 111.
