Description

Technical Field

[0001] This utility model belongs to the field of coating machine technology, and in particular relates to a coating die head for a coating machine. Background Technology

[0002] Hot melt adhesive spraying and extrusion coating machines primarily involve heating and melting solid adhesives, then using a hydraulic device to spray the adhesive directly onto the substrate through a coating die. Therefore, the hydraulic coating die is a crucial component of the hot melt adhesive spraying and extrusion coating machine, typically consisting of a coating nozzle, a hydraulic cylinder, and a coating roller.

[0003] However, existing technologies have some problems: the coating nozzle on the existing hydraulic coating die head is fixedly connected to the external mounting base. When it is necessary to clean the coating nozzle, the disassembly and assembly steps are cumbersome, time-consuming and labor-intensive. Therefore, we propose a coating die head for a coating machine. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model connects the upper frame and the lower frame to the outside of the coating nozzle. The upper frame and the lower frame are snapped together by the first mounting plate and the second mounting plate, and are fixed with the sealing element. Thus, the mounting base is connected to the outer wall of the coating nozzle to protect the coating nozzle.

[0018] 3. When the combined nozzle is installed inside the upper and lower frames, the protrusion extends into the groove and compresses the buffer spring. With the use of the sealing element, the sealing element is engaged with the upper and lower frames, thereby fixing the combined nozzle. When the combined nozzle needs to be removed, only the sealing element needs to be removed. The buffering force of the buffer spring makes it easy to pop out the combined nozzle, thus achieving the purpose of quick disassembly.

[0019] 4. In this utility model, the sealing plate is placed close to the upper and lower frames, and the plug shaft is inserted into the first and second plug holes to achieve a limiting connection between the sealing plate and the upper and lower frames. During the process of the fixing block extending into the upper and lower frames, the telescopic block contacts the inner wall of the upper and lower frames. Under the action of force, it drives the telescopic spring to retract into the stepped hole. When the stepped hole corresponds to the first and second limiting holes, the telescopic spring rebounds, which facilitates the telescopic block to extend into the first and second limiting holes to limit and fix the fixing block. The through hole provided on the fixing block facilitates the glue outlet to extend to the outside. Attached Figure Description

Detailed Implementation

[0028] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0029] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1:

[0031] like Figure 1 and Figure 2As shown in the figure, a coating die head for a coating machine provided by this utility model includes a coating nozzle 4, a coating roller 5 located below the coating nozzle 4, and a hydraulic cylinder connected to the coating nozzle 4 via a connecting pipe. The coating nozzle 4 includes a combined nozzle 2, a mounting base 1 sleeved on the outside of the combined nozzle 2, and a sealing element 3 sealing the mounting base 1. The combined nozzle 2 has an adhesive inlet 21 at its upper end and an adhesive outlet 22 connected to its right side. The mounting base 1 includes an upper frame 11 and a lower frame 12. The upper frame 11 and the lower frame 12 are respectively connected to a first mounting plate 112 and a second mounting plate 122 at their rear sides. The upper frame 11 and the lower frame 12 are engaged by the first mounting plate 112 and the second mounting plate 122. The upper end face of the upper frame 11 has a fixing groove 111, which is the upper end of the adhesive inlet 21. The sealing element 3 includes a sealing plate 31. A side plate 32 is integrally formed on one side. The side plate 32 is inserted into the first mounting plate 112 and the second mounting plate 122. A fixing block 33 is fixedly connected to one end of the sealing plate 31 near the upper frame 11 and the lower frame 12. The fixing block 33 extends into the interior of the upper frame 11 and the lower frame 12. The sealing element 3 is fixedly connected to the upper frame 11 and the lower frame 12 through the fixing block 33 and the side plate 32. By connecting the upper frame 11 and the lower frame 12 to the outside of the coating nozzle 4, the upper frame 11 and the lower frame 12 are snapped together by the first mounting plate 112 and the second mounting plate 122, and the upper frame 11 and the lower frame 12 are fixed together with the sealing element 3. Thus, the mounting base 1 is connected to the outer wall of the coating nozzle 4 to protect the coating nozzle 4. When the coating nozzle 4 needs to be disassembled and cleaned, it is only necessary to remove the sealing element 3 from between the upper frame 11 and the lower frame 12, which facilitates the removal of the upper frame 11 and the lower frame 12 and the cleaning of the coating nozzle 4.

[0032] like Figures 3 to 4As shown, the first mounting plate 112 has an inwardly recessed first insertion hole 1121 on its right outer wall, and an insertion block 115 is fixedly connected to the lower end of the first mounting plate 112. The outer wall of the insertion block 115 has multiple first threaded holes 1151 penetrating through it. The upper end face of the upper frame 11 has a first limiting hole 113, and a locking block 114 is fixedly connected to the lower end of the upper frame 11. The upper end face of the lower frame 12 has an inwardly recessed slot 124 for receiving the locking block 114, and the slot 124 is located to the left of the slot 121. The second mounting plate 122 has an inwardly recessed second insertion hole 1221 on its right outer wall, and an inwardly recessed insertion groove 1223 on its upper end face. The insertion groove 1223 facilitates the receipt of the insertion block 115, and the outer wall of the second mounting plate 122 has multiple second threaded holes 1151 penetrating through it. 222, the second threaded hole 1222 communicates with the insertion slot 1223, the second threaded hole 1222 corresponds to the first threaded hole 1151, and a threaded shaft 13 is threadedly connected inside the second threaded hole 1222. The threaded shaft 13 is threadedly connected to the second threaded hole 1222 and the first threaded hole 1151. The locking block 114 extends into the locking slot 124, and the insertion block 115 extends into the insertion slot 1223, which facilitates the limiting connection between the upper frame 11 and the lower frame 12. The threaded shaft 13 passes through the second threaded hole 1222 on the second mounting plate 122 and extends into the first threaded hole 1151 on the insertion block 115, which facilitates the fixed connection of the insertion block 115 inside the insertion slot 1223, thereby realizing the fixed connection between the upper frame 11 and the lower frame 12, which facilitates the disassembly and installation between the upper frame 11 and the lower frame 12.

[0033] like Figures 3 to 4 As shown, the lower frame 12 has a groove 125 on its left inner wall, and a buffer spring 126 is fixedly connected inside the groove 125; the combined nozzle 2 has a protrusion 23 that fits into the groove 125 on its left outer wall; when the combined nozzle 2 is installed inside the upper frame 11 and the lower frame 12, the protrusion 23 extends into the groove 125 and compresses the buffer spring 126. With the use of the sealing member 3, the sealing member 3 engages with the upper frame 11 and the lower frame 12, thereby fixing the combined nozzle 2. When the combined nozzle 2 needs to be removed, only the sealing member 3 needs to be removed. The buffering force of the buffer spring 126 makes it easy to pop out the combined nozzle 2, thus achieving the purpose of quick disassembly.

[0034] like Figures 6 to 7As shown, a positioning block 34 is fixedly connected to one side of the sealing plate 31 that extends into the upper frame 11 and the lower frame 12. The positioning block 34 extends into the slot 121 and is fixedly connected to the fixing block 33. A through hole 331 is provided through the end face of the fixing block 33 for connecting the glue outlet 22. Stepped holes 334 are provided on both the upper and lower end faces of the fixing block 33. The stepped holes 334 are located on the upper and lower sides of the through hole 331. A telescopic block 332 is connected inside the stepped hole 334. A telescopic spring 333 is connected to one end of the telescopic block 332 inside the stepped hole 334. The other end of the telescopic spring 333 is connected to the inner wall of the stepped hole 334. The end of the telescopic block 332 that extends out of the stepped hole 334 is engaged with the first limiting hole 113 and the second limiting hole 123. The side plate 32 is located on the side close to the first mounting plate 112 and the second mounting plate 122. Two insertion shafts 321 are connected to the outer wall, and the insertion shafts 321 extend into the first insertion hole 1121 and the second insertion hole 1221. When the sealing plate 31 is brought close to the upper frame 11 and the lower frame 12, the insertion shafts 321 are inserted into the first insertion hole 1121 and the second insertion hole 1221, so as to achieve a limiting connection between the sealing plate 31 and the upper frame 11 and the lower frame 12. During the process of the fixing block 33 extending into the upper frame 11 and the lower frame 12, the telescopic block 332 and the upper frame... When the 11 and the inner wall of the lower frame 12 come into contact, the tension spring 333 is driven to retract into the stepped hole 334 under the action of force. When the stepped hole 334 corresponds to the first limiting hole 113 and the second limiting hole 123, the tension spring 333 rebounds, so that the telescopic block 332 can extend into the first limiting hole 113 and the second limiting hole 123 to limit and fix the fixing block 33. The through hole 331 provided on the fixing block 33 facilitates the glue outlet 22 to extend to the outside.

[0035] Working principle of Example 1:

[0036] During use, when the combined nozzle 2 is installed inside the upper frame 11 and lower frame 12, the protrusion 23 extends into the groove 125, compressing the buffer spring 126. In conjunction with the use of the sealing element 3, the sealing plate 31 is brought close to the upper frame 11 and lower frame 12. The insertion shaft 321 is inserted into the first insertion hole 1121 and the second insertion hole 1221, achieving a limiting connection between the sealing plate 31 and the upper frame 11 and lower frame 12. During the process of the fixing block 33 extending into the upper frame 11 and lower frame 12, the telescopic block 332 contacts the inner wall of the upper frame 11 and lower frame 12. Under the action of force, it drives the telescopic spring 333 to retract into the stepped hole 334. When the stepped hole 334... When corresponding to the first limiting hole 113 and the second limiting hole 123, the telescopic spring 333 rebounds, allowing the telescopic block 332 to extend into the first limiting hole 113 and the second limiting hole 123, limiting and fixing the fixing block 33, thereby fixing the combined nozzle 2 inside the mounting base 1. When it is necessary to disassemble the combined nozzle 2, simply press the two telescopic blocks 332 to move the telescopic blocks 332 away from the first limiting hole 113 and the second limiting hole 123. When the limiting holes are not under force, the seal 3 loses its limiting effect on the combined nozzle 2, so the buffer spring 126 can buffer and quickly pop the combined nozzle 2 into the mounting bracket, achieving quick disassembly.
