[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0025] As shown in Figure 1 and 2 A glue spraying device of a blanket making machine comprises a stand 13, the stand 13 is connected with a cantilever 11, a sliding table 2 and a cylinder 8 are installed on the cantilever 11, a piston rod of the cylinder 8 is connected with a first sliding block in the sliding table 2, a support 6 is fixedly connected on the sliding block, the support 6 is transversely arranged above a blanket, a glue inlet pipe 4 and a glue spraying rod 22 are fixedly connected on the support 6, a plurality of straight nozzles 3 are installed on the glue spraying rod 22, the straight nozzles 3 are suitable for linear glue application, upper ends of the straight nozzles 3 are communicated with the glue inlet pipe 4, the glue inlet pipe 4 is communicated with a glue conveying pump 21 and a glue storage tank 18 through a hose 17, and the glue conveying pump 21 is selected from a gear pump.

[0026] In implementation, the blanket making machine conveys the blanket from below the straight nozzles 3, in the process of conveying the blanket, the glue conveying pump 21 is started, the glue in the glue storage tank 18 is drawn by the glue conveying pump 21 and flows to the blanket from the straight nozzles 3, at the same time, the cylinder 8 drives the straight nozzles 3 to reciprocally move, so that the linear glue sprayed by the straight nozzles 3 is coated on the blanket in a wavy line.

[0027] Compared with the traditional spray glue, the linear glue spraying method can effectively reduce the waste of hot melt glue, avoid the adverse effects of misty glue on the environment and human health, and also ensure that the glue can be accurately sprayed on the blanket, thereby improving the efficiency and quality of glue spraying.

[0028] Further, the stand 13 is connected with the cantilever 11 through a lifting mechanism, the lifting mechanism comprises a guide rail 12 installed on the stand 13, a second sliding block is assembled on the guide rail 12, an angle plate 10 is fixedly connected on the second sliding block, and a reduction motor 14 and a chain and sprocket transmission mechanism 9 are assembled at the lower end of the stand 13, the reduction motor 14 is connected and driven with the angle plate 10 through the chain and sprocket transmission mechanism 9.

[0029] In implementation, this structure enables the straight nozzles 3 to move up and down, so that the glue spraying distance can be flexibly adjusted according to the thickness of the blanket or the glue spraying requirement, so as to achieve the best glue spraying effect. In addition, when the straight nozzles 3 need to be replaced or repaired, the straight nozzles 3 can also be conveniently moved to a suitable position for operation, thereby improving the maintainability and operation convenience of the equipment.

[0030] Further, the speed reducer motor 14 is a worm gear speed reducer motor 14. When the straight nozzle 3 is adjusted to the appropriate height, the worm gear speed reducer motor 14 can automatically lock the position to prevent the straight nozzle 3 from moving unexpectedly due to external force or other factors, thereby ensuring the stability and reliability of the position of the straight nozzle 3 during the glue spraying process, further improving the uniformity and quality of the glue spraying.

[0031] Further, an accordion track dust cover 7 is installed on the sliding table 2. The installation of the accordion track dust cover 7 on the sliding table 2 can effectively prevent dust, impurities, and the like from entering the inside of the sliding table 2. If dust and other impurities enter the sliding table 2, they may cause the mechanical wear of the sliding table 2 to intensify, affecting its running accuracy and service life. By setting the dust cover 7, such wear can be reduced, the service life of the sliding table 2 can be extended, the maintenance cost of the equipment can be reduced, and at the same time, the stable operation of the sliding table 2 can be ensured, thereby ensuring the smoother and more accurate reciprocating motion of the straight nozzle 3.

[0032] Further, a heating tape 19 is provided on the glue storage tank 18, the straight nozzle 3, the glue inlet pipe 4, and the hose 17. And a thermal insulation layer is wrapped outside these components. When using hot melt glue, the heating tape 19 can heat the glue to prevent it from cooling and solidifying during transportation, ensuring that the glue can be smoothly transported from the glue storage tank 18 to the straight nozzle 3 and uniformly sprayed onto the impermeable blanket. The thermal insulation layer can further reduce heat loss, maintain the temperature of the glue stable, improve the stability and reliability of the glue spraying, and avoid poor glue spraying effect or equipment failure due to temperature changes of the glue.

[0033] Further, a thermal insulation layer (not shown in the thermal insulation layer diagram) is wrapped outside the glue storage tank 18, the straight nozzle 3, the glue inlet pipe 4, and the hose 17. The thermal insulation layer can effectively reduce heat loss, maintain a relatively stable temperature of the glue during transportation, and avoid changes in the viscosity of the glue due to large temperature changes, thereby ensuring the uniformity and continuity of the glue spraying. At the same time, the thermal insulation layer can also help improve the energy efficiency of the equipment, reduce energy waste, and reduce the operating cost of the equipment.

[0034] Further, a temperature sensor is provided on the glue storage tank 18, and the temperature sensor and the heating tape 19 are connected to a temperature controller. Through the temperature controller, a suitable temperature range can be set according to the properties of the glue and the glue spraying requirements, so that the heating tape 19 can automatically adjust the heating power to ensure that the glue always maintains the best working temperature. This temperature control method not only improves the quality and stability of the glue spraying, but also avoids damage to the glue or equipment due to excessively high or low temperature, prolongs the service life of the equipment, and improves the safety and reliability of the equipment.

[0035] Further, two magnetic switches 16 are installed on the air cylinder 8, the magnetic switches 16 are connected to the input end of the controller, the electromagnetic valve connected to the output end of the controller is used for controlling the extension and retraction of the air cylinder 8, and a touch screen is further included, the touch screen and the temperature controller are in communication connection with the controller. The controller used is Siemens 1200 1214DC PLC, the temperature controller is Delta DTK 4848V12, and the touch screen is Kunlun Tongtai TPC7062Ti, the temperature controller and the PLC are connected using an RS485 interface, the touch screen and the PLC are connected using an RS232 or Ethernet interface, and the communication protocol is Modbus RTU.

[0036] This structure realizes accurate control of the extension and retraction of the air cylinder 8, the position state of the air cylinder 8 can be monitored in real time through the magnetic switches 16, the controller controls the opening and closing of the electromagnetic valve according to the information, thereby realizing accurate control of the extension and retraction distance of the air cylinder 8, ensuring that the reciprocating movement of the straight nozzle 3 is more stable and uniform, in addition, the position of the magnetic switch 16 on the air cylinder 8 is adjusted to adjust the glue spraying width of the straight nozzle 3. The touch screen provides an intuitive operation interface for the operator, various parameters such as the extension and retraction speed of the air cylinder 8, the glue spraying time, the temperature and the like can be conveniently set and adjusted, and the operation convenience and the automation degree of the equipment are improved. At the same time, the communication connection of the touch screen and the temperature controller with the controller realizes centralized control and monitoring of the entire glue spraying device, improves the intelligent level of the equipment, reduces the labor intensity of the operator, and improves the production efficiency.
