[0002] Currently in the industry, equipment for coating the surface of substrates such as steel wire / fiber fabrics with glue generally uses a single-screw extruder to install a wide-width die, in which the glue output direction of the die (the forward direction of the substrate) is perpendicular to the extrusion direction of the screw. In order to facilitate the cleaning of the rubber and the installation of components, the die is generally divided into left and right parts, which are connected by locking screws and nuts. Specifically, after the left and right die bodies slide or rotate to close the mold, screws are used to penetrate the left and right die bodies, and the nuts are tightened to lock them.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to solve the problem that the glue coating head in the prior art is inconvenient to disassemble, the present invention provides a glue coating head.

[0029] Please refer to Figures 1 to 6 , a glue coating head is used to coat glue on the surface of a substrate 90, and the glue coating head includes: a body 10; a flow channel component 20, the flow channel component 20 is movably arranged relative to the body 10, wherein the flow channel component 20 is provided with a material delivery channel 21 for conveying the substrate 90 and a glue delivery channel 22 for conveying the glue; a mouth component 30, the mouth component 30 is connected to the flow channel component 20, and the mouth component 30 is provided with a material delivery port 31 for outputting the glue-coated substrate 90; wherein, after the flow channel component 20 and the mouth component 30 are connected, a glue coating cavity 32 is formed, and the material delivery channel 21 and the glue delivery channel 22 are respectively connected to the glue coating cavity 32, so that the substrate 90 is coated with glue in the glue coating cavity 32.

[0030] The present invention provides a glue coating machine head, which is mainly used for coating the surface of a substrate 90 such as a steel wire or a fiber fabric with glue. In order to facilitate installation and disassembly, the glue coating machine head is divided into three main parts: a machine body 10, a die assembly 30 and a flow channel assembly 20. The machine body 10 is fixed on a mounting bracket 80, and the die assembly 30 and the flow channel assembly 20 can both move relative to the machine body 10, so that when it is necessary to coat the substrate 90 with glue, the die assembly 30 and the flow channel assembly 20 are respectively moved close to the machine body 10 to connect with the machine body 10. Next, a material delivery channel 21 for passing through the substrate 90 is provided in the flow channel component 20. After the flow channel component 20 is connected to the body 10, a glue delivery channel 22 for circulating the glue is formed between the two. One end of the glue delivery channel 22 is connected with one end of the material delivery channel 21 in the glue coating cavity 32, so as to achieve glue coating on the substrate 90. When use is completed or the glue needs to be replaced, the mouth component 30 and the flow channel component 20 are moved away from the body 10, so as to facilitate cleaning of the mouth component 30, the body 10 and the flow channel component 20.

[0031] The process of gluing the substrate 90 is as follows: the substrate 90 passes through the feed channel 21 and enters the glue coating chamber 32 , the glue flows through the feed channel 22 and enters the glue coating chamber 32 , and then the glue is coated on the substrate 90 , and finally the die assembly 30 shapes the glue on the substrate 90 , and outputs the glued substrate 90 from the feed port 31 .

[0032] The coating head also includes: a locking assembly 40, which is arranged on the machine body 10, and is used to lock the flow channel assembly 20 and / or the mouth assembly 30 on the machine body 10. The locking assembly 40 includes a plurality of first drive assemblies 41, and the plurality of first drive assemblies 41 are respectively arranged on the machine body 10, wherein the first drive assembly 41 includes: a first drive part 411, which is arranged on the machine body 10; a first locking plate 412, which is drivingly connected to the first drive part 411, and is used to drive the first locking plate 412 to move, wherein the first locking plate 412 has a first locking position and a first avoidance position, so that the flow channel assembly 20 is fixed on the machine body 10 when the first locking plate 412 moves to the first locking position, and when the first locking plate 412 moves to the first avoidance position, the flow channel assembly 20 can be moved relative to the machine body 10. The locking assembly 40 includes a plurality of second drive assemblies 42, which are respectively arranged on the body 10, wherein the locking assembly 40 includes a second drive assembly 42, and the second drive assembly 42 includes: a second drive part 421, which is arranged on the body 10; a second locking plate 422, which is drivingly connected to the second drive part 421 to drive the second locking plate 422 to move, wherein the second locking plate 422 has a second locking position and a second avoidance position, so as to fix the mouth-shaped assembly 30 on the body 10 when the second locking plate 422 moves to the second locking position, and enable the mouth-shaped assembly 30 to move relative to the body 10 when the second locking plate 422 moves to the second avoidance position.

[0033] like Figure 1 As shown, in this embodiment, in order to make the mouth-shaped component 30, the machine body 10 and the flow channel component 20 always tightly connected during the gluing process and prevent leakage, a locking component 40 is provided. The first driving component 41 of the locking component 40 is used to fix the flow channel component 20 in the machine body 10 when the flow channel component 20 is inserted into the cavity of the machine body 10 from one end of the machine body 10. At the same time, the second driving component 42 of the locking component 40 is used to fix the mouth-shaped component 30 in the machine body 10 when the mouth-shaped component 30 is inserted into the machine body 10 from the other end of the machine body 10. Specifically, when the locking component 40 locks the mouth-shaped component 30 and the flow channel component 20, the driving cylinder is used to drive the locking plate to move up and down to fix the mouth-shaped component 30 and the flow channel component 20 in the machine body 10. When the coating head needs to be disassembled, the oil cylinder is first driven to drive the locking plate to retract, so that the mouth assembly 30 and the flow channel assembly 20 can move relative to the machine body 10. When the coating head needs to be installed, the flow channel assembly 20 and the mouth assembly 30 are first pushed into the machine body 10 respectively, and then the oil cylinder is driven to drive the locking plate to extend, so as to block the mouth assembly 30 and the flow channel assembly 20 in the machine body 10.

[0034] In order to ensure the fixing effect, four second drive assemblies 42 are arranged on the side of the body 10 close to the mouth-type assembly 30, namely: two second drive assemblies 42 are arranged above the body 10 and two second drive assemblies 42 are arranged below the body 10. Similarly, four first drive assemblies 41 are also arranged on the side of the body 10 close to the flow channel assembly 20, two at the upper and lower parts of the body 10, so as to limit the four corner positions of the flow channel assembly 20.

[0035] Furthermore, in order to facilitate the above-mentioned first locking plate 412 to lock the flow channel assembly 20 and the second locking plate 422 to lock the mouth-shaped assembly 30, a wedge-shaped surface is provided on the side of the first locking plate 412, and a wedge-shaped surface is also provided at the position of the flow channel assembly 20 correspondingly. After the flow channel assembly 20 is pushed into the body 10, the first driving part 411 drives the first locking plate 412 to move downward, and the wedge-shaped surface on the first locking plate 412 abuts against the wedge-shaped surface on the flow channel assembly 20, applying a thrust toward the other side of the body 10 to the flow channel assembly 20 to prevent the flow channel assembly 20 from loosening; similarly, wedge-shaped surfaces are also provided at the corresponding positions of the second locking plate 422 and the mouth-shaped assembly 30, so that after the second locking plate 422 abuts against the mouth-shaped assembly 30, a thrust toward the flow channel assembly 20 is applied to the mouth-shaped assembly 30, thereby tightly connecting the mouth-shaped assembly 30, the flow channel assembly 20 and the substrate.

[0036] In addition, in order to ensure that the above-mentioned first locking plate 412 can be connected to the corresponding position of the flow channel assembly 20 when it moves downward, a first guide plate 413 is also provided in the present embodiment, and the first guide plate 413 has a first guide groove, so that the first locking plate 412 can move along the guide direction of the guide groove under the drive of the first driving part 411. Similarly, in order to ensure that the second locking plate 422 can correspond to the position of the mouth-shaped assembly 30 when it moves downward, a second guide plate 423 for guiding the second locking part is also provided on the laminating machine head, and a second guide groove is provided in the second guide plate 423, so that the second locking plate 422 can move along the second guide groove.

[0037] The first driving part 411 and the second driving part 421 in the present application can be driven by an oil cylinder or a pneumatic cylinder as required.

[0038] The flow channel assembly 20 includes a first flow channel structure 23 and a second flow channel structure 24, and the first flow channel structure 23 and the second flow channel structure 24 are hingedly connected, wherein a first feed trough is provided on the first flow channel structure 23, and a second feed trough is provided on the second flow channel structure 24, and the first feed trough and the second feed trough are correspondingly arranged in position, so that after the first flow channel structure 23 and the second flow channel structure 24 are closed and connected, the first feed trough and the second feed trough form a feed channel 21.

[0039] like Figure 5 and Figure 6 As shown, the flow channel assembly 20 in this embodiment includes a first flow channel structure 23 and a second flow channel structure 24 which are arranged in an upper and lower manner. The first flow channel structure 23 is hingedly connected to the second flow channel structure 24 so as to be able to be closed or opened. The feed template 25 is detachably installed in the second feed trough of the second flow channel structure 24. When the feed channel 21 needs to be cleaned, the first flow channel structure 23 and the second flow channel structure 24 are opened to clean the first feed trough and the second feed trough respectively, which is more convenient.

[0040] The flow channel assembly 20 also includes: a feed template 25, which is detachably disposed on the feed channel 21, wherein there are multiple feed templates 25, and according to the size of the substrate 90, multiple feed templates 25 can be selectively installed on the feed channel 21 to allow the substrate 90 to pass through the feed template 25 and enter the glue coating cavity 32.

[0041] like Figure 6 As shown, in order to facilitate the accurate passage of profiles of various sizes through the feed channel 21, a feed template 25 is provided in the feed channel 21 of the flow channel assembly 20 in the present embodiment. When designing the feed template 25, multiple feed templates can be designed according to the commonly used sizes of substrates 90. When a substrate 90 of a certain size needs to be coated with glue, a feed template 25 of a corresponding size is selected and installed in the feed channel 21, so that the substrate 90 can accurately and smoothly pass through the feed template 25 and enter the glue coating cavity 32 for coating with glue.

[0042] The flow channel assembly 20 includes a first flow channel structure 23 and a second flow channel structure 24, and the first flow channel structure 23 and the second flow channel structure 24 are hingedly connected, wherein the first flow channel structure 23 is provided with a first glue delivery groove 232, and the second flow channel structure 24 is provided with a second glue delivery groove 242. After the first flow channel structure 23 and the second flow channel structure 24 are closed and connected, the glue delivery channel 22 includes a first space jointly surrounded by the first glue delivery groove 232 and the body 10 and a second space jointly surrounded by the second glue delivery groove 242 and the body 10, and the first space is connected to the second space to form the glue delivery channel 22.

[0043] In order to facilitate the cleaning of the glue delivery channel 22, in this embodiment, the structure surrounding the glue delivery channel 22 is divided into two parts, one part is located on the flow channel component 20, and the other part is located on the body 10. The two parts are combined to form the glue delivery channel 22, which is more convenient for disassembly and cleaning. Specifically, the flow channel component 20 is a truncated cone structure, the end with a small radius is on the inner side of the body 10, and the part with a large radius is located on one side of the body 10. The truncated cone structure is divided into an upper and lower part, the upper part is a first flow channel structure 23, and the lower part is a second flow channel structure 24. A first glue delivery groove 232 is provided on one side of the side wall of the first flow channel structure 23, and a second glue delivery groove 242 is provided on one side of the side wall of the second flow channel structure 24. The first glue delivery groove 2 32 is arranged corresponding to the position of the second glue delivery groove 242, and the first glue delivery groove 232 extends to the contact surface of the first flow channel structure 23 and the second flow channel structure 24 and the end with a small radius, and the second glue delivery groove 242 extends to the contact surface of the second flow channel structure 24 and the first flow channel structure 23 and the end with a small radius, so that after the first flow channel structure 23 and the second flow channel structure 24 are closed, the first glue delivery groove 232 and the second glue delivery groove 242 form a groove for circulating the glue. When the flow channel component 20 is inserted into the body 10, the groove and the inner wall of the body 10 jointly form a glue delivery channel 22. In addition, a flow channel connected to the groove is also provided in the flow channel component 20 to transport the glue into the groove.

[0044] The mouth component 30 is provided with a glue coating groove. After the mouth component 30, the flow channel component 20 and the body 10 are connected, the glue coating groove, the flow channel component 20 and the body 10 together form a glue coating cavity 32 to communicate with the glue delivery channel 22 and the material delivery channel 21 respectively.

[0045] like Figure 5 and Figure 6 As shown, a glue coating groove is provided on the surface of the mouth component 30 opposite to the flow channel component 20. When the mouth component 30, the flow channel component 20 and the base are connected, the glue coating groove, the body 10 and the flow channel component 20 together form a glue coating cavity 32. The glue coating cavity 32 is connected with the feed channel 21, the glue feed channel 22 and the feed port 31. The base material 90 is adhered with glue after passing through the glue coating cavity 32. A pressing component is provided at the feed port 31. The pressing component is used to press the glue onto the base material 90 and has an interference fit with the base material 90.

[0048] In addition, in order to facilitate the movement of the flow channel assembly 20, a guide cylinder 70 is also provided on the mounting bracket 80. The guide cylinder 70 is connected to the flow channel assembly 20 to drive the flow channel assembly 20 to move along the first slide rail assembly 50. In addition, a guide cylinder 70 is also provided on the mounting bracket 80 on one side of the mouth type assembly 30 to push the mouth type assembly 30 to move along the second slide rail assembly 60.

[0050] In the present embodiment, in order to achieve a better fusion effect between the rubber and the substrate 90, heating components are respectively provided on the flow channel component 20 and the mouth component 30. In order to facilitate heating, in the present embodiment, liquids such as oil or water with a preset temperature are used, and heating channels are respectively provided on the flow channel component 20 and the mouth component 30.
