Description

Technical Field

[0001] This utility model relates to the field of coating machine heads, specifically a butyl rubber coating machine with positioning function. Background Technology

[0002] There are various coating schemes, such as coating rollers and coating heads. The coating mechanism uses a slit extrusion method to extrude butyl rubber from a slit. The extruded butyl rubber then comes into contact with the surface of the substrate, achieving the coating effect on the substrate.

[0003] In the existing technology, the upper and lower heads of the coating machine are generally equipped with positioning pins and positioning holes at the docking position to avoid the alignment installation of the upper and lower heads.

[0004] However, the above method requires that multiple positioning pins and positioning holes be aligned synchronously when docking the upper and lower machine heads in order to perform positioning and installation. However, during the docking process, the position of the upper machine head needs to be continuously adjusted until the multiple positioning pins and multiple positioning holes are aligned one by one. This method is relatively time-consuming during the docking process of the upper and lower machine heads. Utility Model Content

[0005] The purpose of this invention is to provide a butyl rubber coating machine with positioning function in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a butyl rubber coating machine with positioning function, including a lower die head, an upper die head is installed on the top of the lower die head through a positioning mechanism, a gasket is installed on the mating surface of the lower die head and the upper die head, the gasket has a "C" shaped structure, and the lower die head, the upper die head and the notch position of the gasket form an extrusion slit.

[0007] As a further embodiment of this utility model: the positioning mechanism includes a positioning pin integrally formed on the top of the lower machine head, the top of the positioning pin is provided with a downwardly recessed screw hole, the inside of the gasket and the inside of the upper machine head are provided with positioning holes that match the outer wall of the positioning pin, and a locking bolt is inserted into the positioning hole located inside the upper machine head.

[0008] As a further embodiment of this utility model, the positioning mechanism further includes limiting grooves formed at both ends of the upper head and the gasket, and a fixing limiting plate integrally formed at both ends of the top of the lower head.

[0009] As a further embodiment of this utility model: the positioning mechanism further includes a guide hole that is recessed downward at the top of the fixed limiting plate, a sliding plug that is slidably installed on the inner wall of the guide hole, a rubber damping layer that is wrapped around the outer periphery of the sliding plug, an upwardly protruding lifting shaft integrally formed at the top of the sliding plug, an upwardly protruding sliding limiting plate that is fixedly installed at the top of the lifting shaft, and a hand hole that is opened on the outer side of the sliding limiting plate.

[0010] As a further embodiment of this utility model: a flow channel is provided at the top of the lower head, and a feed pipe connected to the inner cavity of the flow channel is fixedly installed at the tail end of the lower head.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting sliding limit plates and fixed limit plates, it is possible to stretch the four sliding limit plates to different heights during the docking process. Then, by gradually lowering the upper head, the plates are gradually aligned one by one. When the limit plates and limit slots are aligned one by one during the lowering process, multiple positioning pins and multiple positioning holes are aligned one by one, which facilitates the positioning and installation of the upper and lower heads.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 In this embodiment of the present invention, a butyl rubber coating machine with positioning function includes a lower head 1. An upper head 2 is installed on the top of the lower head 1 through a positioning mechanism. A gasket 3 is installed on the mating surface of the lower head 1 and the upper head 2. The gasket 3 has a "C" shaped structure. The lower head 1, the upper head 2, and the notch position of the gasket 3 form an extrusion slit. A flow channel 11 is opened at the top of the lower head 1. A feed pipe 9 connected to the inner cavity of the flow channel 11 is fixedly installed at the tail end of the lower head 1.

[0020] In this embodiment: First, the molten butyl rubber at high temperature is pumped into the feed pipe 9. The molten butyl rubber enters the flow channel 11 through the feed pipe 9 and is then extruded outward through the extrusion slit. The extruded butyl rubber comes into contact with the surface of the substrate being transported. After contact, the substrate drives the butyl rubber to move. After extrusion, the device needs to be disassembled and cleaned to prevent butyl rubber residue from solidifying inside the device.

[0021] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The positioning mechanism includes a positioning pin 4 integrally formed on the top of the lower head 1. A screw hole 5 with a downward recess is provided on the top of the positioning pin 4. Positioning holes 6 that match the outer wall of the positioning pin 4 are provided inside the gasket 3 and the upper head 2. A locking bolt 10 is inserted into the positioning hole 6 located inside the upper head 2.

[0022] In this embodiment: When disassembling the device, a wrench is used to connect with the top end of the locking bolt 10, and the locking bolt 10 is rotated by the wrench. The rotating locking bolt 10 is separated from the screw hole 5 until the locking bolt 10 is completely separated from the screw hole 5. At this time, the upper head 2 and the lower head 1 are no longer restricted by the locking bolt 10. At this time, the upper head 2 can be disassembled, and then the gasket 3 can be removed. After disassembly, the corresponding cleaning can be carried out to avoid the butyl rubber residue from hardening.

[0023] After cleaning, during installation, align the positioning holes 6 on the gasket 3 with the positioning pins 4 one by one, then lower the gasket 3 until the bottom of the gasket 3 contacts the top surface of the lower head 1. Then move (or hoist) the upper head 2 and move the upper head 2 above the lower head 1.

[0024] Please refer to this carefully. Figure 3 and Figure 4The positioning mechanism also includes limiting grooves 8 opened at both ends of the upper head 2 and the pad 3, and fixed limiting plates 7 integrally formed at both ends of the top of the lower head 1. The positioning mechanism also includes a guide hole 16 opened at the top of the fixed limiting plate 7 and recessed downward. A sliding plug 15 is slidably installed on the inner wall of the guide hole 16. A rubber damping layer is wrapped around the outer periphery of the sliding plug 15. An upwardly protruding lifting shaft 14 is integrally formed at the top of the sliding plug 15. An upwardly protruding sliding limiting plate 12 is fixedly installed at the top of the lifting shaft 14. A hand hole 13 is opened on the outer side of the sliding limiting plate 12.

[0025] In this embodiment: after the upper head 2 moves to directly above the lower head 1, the four sliding limit plates 12 are pulled upward. The sliding limit plates 12 drive the sliding plug 15 upward through the lifting shaft 14. Since the outer periphery of the sliding plug 15 has a rubber damping layer, when the sliding plug 15 is not under force, the sliding plug 15 stays at the current position under the limit of friction.

[0026] At this point, the four sliding limit plates 12 should be misaligned. One sliding limit plate 12 should be at its highest position, another sliding limit plate 12 diagonally opposite the highest position should be at its second highest position, and the other two sliding limit plates 12 should be at their third and fourth highest positions (regardless of position). Then, when lowering the upper machine head 2, one of the limit grooves 8 on the upper machine head 2 should align with the highest sliding limit plate 12. If they are not aligned, the position of the upper machine head 2 should be adjusted until one of the limit grooves 8 aligns with the highest sliding limit plate 12. The upper head 2 is then docked with the sliding limit plate 12 at the highest position. At this time, the other three do not interfere with the adjustment of the position of the upper head 2, which can form a relatively convenient docking. Then, the upper head 2 is continuously lowered. After the sliding limit plate 12 at the highest position docks with one limit groove 8, the sliding limit plate 12 at the second highest position can dock with another limit groove 8 relatively easily. Finally, the upper head 2 continues to be lowered, driving the other two sliding limit plates 12 to dock with the remaining two limit grooves 8, achieving the technical effect of easy docking.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
