[0021] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0022] The utility model provides Figure 1-Figure 4 A PUR slit-type extrusion gluing and glue-controlling extrusion device shown includes a support assembly 17 installed on a coating machine 1 and a glue barrel body 2 storing glue. The glue barrel body 2 is located on one side of the coating machine 1. A temperature-adjustable glue station body 4 is provided at the top of the support assembly 17. The glue station body 4 is connected to the glue barrel body 2 through a main glue channel 7. The bottom end of the glue station body 4 is connected to a plurality of glue distribution channels 9 for conveying glue. The ends of the plurality of glue distribution channels 9 are detachably connected to a glue coating mold 8. The plurality of glue distribution channels 9 can control the colloid flow rate through a regulating valve 10. When gluing fabrics of different sizes, the regulating valve 10 can be controlled through the control panel 3 to close the corresponding glue outlet of the glue distribution channel 9 to avoid material waste.

[0023] The main glue channel 7 is connected to a metering pump 6 for controlling the amount of colloid. A glue pressing disk 15 for heating the colloid is arranged inside the glue barrel body 2. A glue barrel temperature sensor 16 for monitoring the temperature of the colloid is arranged on the inner side wall at the center of the glue pressing disk 15. The temperature of the glue pressing disk 15 is controlled by the control panel 3. The glue barrel temperature sensor 16 and the glue pressing disk 15 are used in conjunction to prevent the fluidity of the colloid inside the glue barrel body 2 from deteriorating due to changes in temperature, which affects the transportation of the colloid.

[0024] A pressure pump 5 for controlling the flow rate of the colloid is installed at one end of the glue station body 4, and a glue station temperature sensor 14 is also provided at the bottom end of the glue station body 4. The glue station temperature sensor 14 is used to check the colloid temperature of the inner wall 13 of the glue station, so as to control the corresponding information of the inner wall 13 of the glue station.

[0025] The glue station body 4 includes a glue station shell 18 for heat preservation, and a glue station inner wall 13 is arranged inside the glue station shell 18. A heating pipe 12 for heating the glue inside the glue station inner wall 13 is arranged on the outer side of the glue station inner wall 13 and the inner side of the glue station shell 18. The glue station shell 18 is a heat-insulating material, and the glue station inner wall 13 is a heat-insulating pressure vessel. The heating pipe 12 can be controlled by the control panel 3.

[0026] The portion of the glue channel 9 located at the bottom of the support assembly 17 is provided with a glue channel temperature sensor 11, which monitors the temperature of the glue channel and feeds back a signal to the warning light in time, so as to correct the corresponding parameters in time.

[0027] The end of the glue coating mold 8 is in contact with the cloth, and the glue outlet of the glue coating mold 8 is a flat slit. A regulating valve 10 for controlling the flow speed of multiple glue distribution channels 9 is installed on one side wall of the glue coating mold 8. A warning light is provided on the outer side wall of the regulating valve 10. The regulating valve 10 is an electronic valve. The warning light provided on the electronic valve, when a red alarm is on the electronic valve, the mold temperature at the glue inlet is too high, a green alarm is on the electronic valve, the mold temperature at the glue inlet is too low, a yellow alarm is on the electronic valve, the glue inlet is insufficient, a blue alarm is on the electronic valve, and the alarm without a light is a normal state. Through the monitoring of multiple warning lights, timely feedback can be given to the glue outlet.

[0028] The outer wall of the support assembly 17 is equipped with a control panel 3 for monitoring and controlling the pump body and the sensor. The setting of the control panel 3 can effectively control the glue output of the mold. When the electronic valve alarms, the glue output can be adjusted by adjusting the temperature through the control panel 3 or adjusting the glue output piston on the pressure pump 5, so that the equipment can operate normally for a long time.

[0029] The utility model controls the temperature and pressure of the glue station body 4. When the temperature of the glue outlet mold 8 is too high or too low, or the glue feed volume is too low or too high, the pressure pump 5 and the heating pipe 12 are controlled by the control panel 3 to timely adjust the flow rate of the colloid, so as to avoid the performance of the glue coating mold 8 being changed due to the change of the working environment temperature. By changing the glue outlet size of the glue coating mold 8 and controlling the glue outlet speed and glue outlet volume, the glue coating range and glue coating volume can be effectively controlled. By controlling the variables, the spraying speed, glue outlet volume and spraying pressure of multiple glue outlets are ensured to be the same, thereby improving the uniformity of product gluing. At the same time, the use of glue coating volume can be reduced to achieve the demand of uniform coating, thereby saving production costs.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
