An upper roller base is mounted on the carriage 102, and an upper coating roller 101 is mounted on the upper roller base.
The traveling mechanism may generally adopt a roller, and specifically, the upper traveling mechanism includes a plurality of upper rollers 103 sequentially disposed on the corresponding side of the frame 102 along the axial direction of the upper coating roller, and the axis of the upper roller 103 is perpendicular to the axis of the upper coating roller 101.
When the upper coating roller carriage 100 is used, the first positioning member 104 is engaged with the second positioning member 301 of the upper frame 3001, so that the upper coating roller 101 is kept horizontal, i.e., the axis of the upper coating roller 101 is parallel to the horizontal direction. At this time, the axis of the upper coating roller 101 is perpendicular to the central line of the unit, and the axis of each upper roller 103 is parallel to the central line of the unit; the vertical symmetry plane of the upper coating roller 101 passing through its axis is the reference plane, and the two sets of upper traveling mechanisms are arranged on both sides of the reference plane and are generally symmetrically arranged with respect to the reference plane.

as shown in fig. 1 and 2, an upper coating structure provided in an embodiment of the present invention includes an upper frame 3001, and further includes an upper coating roller 100 provided in the first embodiment, and a specific structure of the upper coating roller 100 is not described herein again. Based on the structure that the upper coating roller car 100 is provided with the first positioning member 104, correspondingly, the top of the upper frame 3001 is provided with the second positioning member 301 adapted to be engaged with the first positioning member 104, the second positioning member 301 is positioned right above the first positioning member 104, and when the upper coating roller 101/the frame 102 is lifted, the first positioning member 104 on the frame 102 can be engaged with the second positioning member 301 on the upper frame 3001.
In the first embodiment, it is mentioned that the first positioning member 104 and the second positioning member 301 are a positioning block and positioning groove matching structure, when the first positioning member 104 is a positioning block, the second positioning member 301 corresponds to a positioning groove, and when the first positioning member 104 is a positioning groove, the second positioning member 301 corresponds to a positioning block.
Based on the structure that the upper coating roller car 100 is provided with the upper traveling mechanisms, correspondingly, two sets of upper rails 302 for the two sets of upper traveling mechanisms to travel respectively are arranged on the upper rack 3001, the two sets of upper rails 302 are respectively arranged on two sides of the frame 102 along the running direction of the strip steel, and the guiding direction of the upper rails 302 is parallel to the horizontal direction and is perpendicular to the central line of the unit. The upper track 302 is provided according to the specific structure of the upper traveling mechanism, which is conventional and will not be described in detail herein. Obviously, the upper rail 302 is a horizontal rail and is provided along the axial direction of the coating roller over the entire length of the upper frame 3001; the upper coater roller 100 is held in a horizontal state while being supported on the upper rail 302.
The upper frame 3001 is a portal frame on both the operating side and the transmission side of the unit, and the portal cross-section of the portal frames on both sides is parallel to the center line of the unit, i.e., perpendicular to the axis of the coating roller 101, perpendicular to the direction of the upper rail 302, and perpendicular to the direction of the groove length of the positioning groove. The two side portal frames are connected through the middle frame, so that the two portal frames are connected into a whole, and the middle frame can be a plurality of connecting rods (the length direction of the connecting rods is parallel to the axial direction of the coating roller) and the like.
In the upper coating structure provided by the embodiment, the first positioning member 104 is arranged on the frame 102 of the upper coating roller trolley 100, the second positioning member 301 is arranged on the upper frame 3001, the first positioning member 104 and the second positioning member 301 can be matched in a manner of matching a positioning block with a positioning groove, so that the upper coating roller 101 is positioned well, the levelness of the upper coating roller 101 is ensured, and the verticality between the axis of the upper coating roller 101 and the central line of a unit is ensured, thereby ensuring the coating quality; meanwhile, the horizontal force applied to the upper coating roller 101 during operation can be transmitted from the first positioning member 104 to the second positioning member 301 and further to the upper frame 3001, so as to ensure the accuracy of the upper coating roller 101.
When the upper coating roller 101 is attached, the axis of the upper coating roller 101 is parallel to the positioning surface of the first positioning member 104.
Further preferably, when the positioning block is matched with the positioning groove, only the positioning surfaces of the positioning block and the positioning groove are in contact, and other non-positioning surfaces are not in contact, namely, a space is formed between the positioning block and the bottom of the positioning groove. As shown in fig. 1, when the positioning block is engaged into the positioning groove, the positioning block does not contact with the bottom of the positioning groove (i.e., the end of the positioning groove far from the notch thereof), and the upper end surface of the positioning groove does not contact with the upper frame 3001, so as to ensure the automatic positioning effect of the upper coating roller 101, and simultaneously, the horizontal force applied to the upper coating roller 101 can be better transmitted to the upper frame 3001.
EXAMPLE III
2-4, an embodiment of the present invention provides a two-roll coating machine, including the upper coating structure provided in the second embodiment;
It further includes a lower coating structure including a lower frame 3002, a lower roller frame 202 installed on the lower frame 3002, a lower roller jacking unit 203 installed on the lower roller frame 202, and a lower coating roller 201 connected with the lower roller jacking unit 203, the lower frame 3002 being connected with the upper frame 3001.
The upper frame 3001 and the lower frame 3002 are connected to form a frame 300 of the coating machine, wherein the connection between the upper frame 3001 and the lower frame 3002 may be an integrally formed structure, for example, the upper frame 3001 is a portal frame on both the operating side and the transmission side of the machine unit, and the vertical columns of the portal frames on both sides extend downward to form the lower frame 3002. Of course, the upper housing 3001 and the lower housing 3002 may be assembled together by using a detachable connection structure.
Similarly, the lower coating roller 201 is rotatably mounted on a lower roller base, which is connected to an output end of the lower roller lifting unit 203. Preferably, the lower roll base is slidably disposed on the lower roll stand 202, and more specifically, the lower roll stand 202 is provided with a guide mechanism for guiding the up-and-down movement of the lower coating roll 201, and the guide mechanism may be a linear guide rail or a guide rod, for example, the lower roll stand 202 is provided with a lower roll guide rail 204, the guide direction of the lower roll guide rail 204 is vertical, the lower roll base is correspondingly provided with a lower roll guide slider, and the lower roll guide slider is slidably disposed on the lower roll guide rail 204.
The lower roll jacking unit 203 can adopt a conventional linear driving mechanism, such as an air cylinder, a hydraulic cylinder and the like, in the embodiment, a worm and gear lifting mechanism is adopted, the jacking driving effect is stable and reliable, and a driving element can adopt a gear motor or a hydraulic motor. The lower roll jacking unit 203 preferably comprises a set of driving devices on the operating side and the transmission side of the unit, so that the lifting stability of the lower coating roll 201 and the levelness of the lower coating roll 201 are guaranteed.
Similarly, it is preferable to provide a lower traveling mechanism 205 on the lower roll stand 202 to facilitate operations such as mounting of the lower roll stand 202, the lower coating roll 201 to the lower frame 3002, or offline maintenance from the lower frame 3002.
