The embodiment of the present application is a kind of for flattening the equipment for producing wide bamboo clappers by providing, and solves and occurs in the prior art Bamboo section the problem of being easy cracking during the exhibition of booth and not adapting to different size bamboos section booth exhibition demand.

Technical solution in the embodiment of the present application is to solve the problems, such as above-mentioned puzzlement, and general thought is as follows:

As shown in Figures 1 to 7, which includes rack 700, and material guide mechanism 100 is provided in rack 700, is cut for that will have The bamboo section of slot is sent along its length direction, and bamboo section, during delivery, the crack in bamboo section is upwardly disposed;Booth exhibition machine Structure 200 is postponed along the length direction of bamboo section and is arranged after material guide mechanism 100 comprising two booth exhibition portions positioned opposite and For the support portion 210 of support bamboo section, two booth exhibition portions compress bamboo section inner wall by extending downwardly, and bamboo section is existed by being located remotely from each other Bamboo clappers is shown laid flat on support portion 210;Shape conveying mechanism 300, and one end intersects arrangement with Tan Zhan mechanism 200, for support The bamboo clappers removed in portion 210 is received and is conveyed, and makes bamboo clappers cooling shaping during transportation.

Equipment provided by the embodiments of the present application for flattening the wide bamboo clappers of production will have by the way that material guide mechanism 100 is arranged The bamboo section for cutting seam is sent along its length direction;By the booth for including support portion 210 and two booth exhibition portions positioned opposite Open up mechanism 200, and stitch upwardly disposed bamboos section by 210 pairs of support portion cuttings and provide a supporting role, then by two booth exhibition portions to Lower extension compresses bamboo section inner wall, and bamboo section is shown laid flat in bamboo clappers in a manner of being located remotely from each other by two booth exhibition portions;Pass through setting setting conveying Mechanism 300 carries out the purpose of cooling shaping for realizing conveying bamboo clappers and to the bamboo clappers in transmission process;By above-mentioned setting, The flattening demand of the bamboo section of sizes can not only be adapted to, but also advantageously reduces cracking of the bamboo section during exhibition of booth Rate.

As shown in Figures 2 to 4, in order to enable bamboo section feeding when posture and exhibition to be spread out in Tan Zhan mechanism 200 bamboo section Posture be consistent, need to bamboo section feeding posture implement adjustment and positioning, the preferred embodiment of the embodiment of the present application are as follows: lead Material mechanism 100 includes the shell 120 for being inserted into the guide axis 110 of bamboo intersegmental part with being fixed at 110 periphery of guide axis, guide Axis 110 is horizontally disposed, is fixedly mounted in rack 700 by sunpender;The maximum of the internal diameter of shell 120 and bamboo to be flared section Outer diameter is adapted, and guide axis 110 and booth exhibition portion are in the arrangement that postpones.It is formed between shell 120 and guide axis 110 and is passed through for bamboo section Delivery cavity, be sent the cross-sectional sizes of cavity and be adapted with the radial dimension range of the bamboo of exhibition to be spread out section, thickness range, and Meet bamboo section during delivery cannot radially displaceable distance it is too big, in order to avoid cause because deviations are larger bamboo section delivery road Diameter cannot be corresponding with booth exhibition portion.

As shown in Figures 1 to 4, although bamboo section is all cut with cutting seam along its length direction in advance before the exhibition of booth, have Bamboo section may be relatively smaller due to sectional dimension, cause booth exhibition portion cannot smoothly move into bamboo section in, in addition, if cutting seam It is smaller, the time needed for will increase booth exhibition bamboo section, it also will affect the production efficiency of bamboo clappers.Therefore in order to which the booth exhibition for improving bamboo section is imitated Rate, the scheme that embodiments herein further provides for are as follows: the equipment further includes flaring mechanism 400, is fixed at guide Mechanism 100 on the path that is sent of bamboo section, for by way of bamboo section on cutting seam carry out expanding seam processing.Its principle It is: during material guide mechanism 100 is sent bamboo section, the cutting in bamboo section is stitched at expansion by flaring mechanism 400 Reason, so that cutting seam increases, to be conducive in booth exhibition portion merging bamboo section and improve the booth exhibition efficiency of bamboo section.

Specifically, as shown in Figures 2 to 4, flaring mechanism 400 can be wedge block 410, wedge block 410 and material guide mechanism The corresponding arrangement of cutting seam of bamboo section, the cross-sectional width of wedge block 410 become larger along the delivery direction of bamboo section on 100, wedge block 410 It is mounted on the top of guide axis 110.

As shown in Figure 3 and Figure 4, for the expansion mode of cutting seam, the embodiment that can also be selected is guide axis 110 Section be gradually increased along the delivery direction of bamboo section, the maximum inner diameter of the minimum outer diameter of guide axis 110 and bamboo to be flared section It is adapted.By the way that bamboo section by guide axis 110, the inner cavity of bamboo section can be increased, while can also play and expand cutting seam Purpose.Certainly, this embodiment can be combined with wedge block 410 and be used together, and can reach expand cutting seam in this way Purpose, moreover it is possible to bamboo section inner cavity be expanded, booth exhibition is carried out to bamboo section to easily facilitate subsequent booth exhibition portion.

As shown in Figures 1 to 4, when guide axis 110 be arranged to above-mentioned section in increase in the form of, the tail end of shell 120 Just should not with the tail end flush arrangement of guide axis 110 because bamboo section sectional dimension gradually support by guide axis 110 greatly it Afterwards, the position in bamboo section at 110 tail end of guide axis is likely to be blocked by 120 inner wall of shell, and bamboo section is thus caused to be difficult to Continuation is sent forward, then will affect being normally carried out for production process.Therefore, the further preferred scheme of the present embodiment are as follows: lead The tail end of material axis 110 extends to the outside of shell 120.More specifically, if guide axis 110 is concordant with the head end of shell 120 Words, then the axial length of guide axis 110 is greater than the length axial along guide axis 110 of shell 120.As for 110 tail end of guide axis Extend to the specific length outside shell 120, can according to the size range of the bamboo of reality exhibition to be spread out section and shell 120 with lead Expect the cavity size between axis 110 and sets.

Due to guide axis 110 be through hanger erection in rack 700, if guide axis 110 bamboo section be sent during, There are axially displaced, bamboo section is just influenced whether and the position corresponding relationship that spreads out exhibition portion, therefore in this case it is necessary to guide The axial freedom of axis 110 further strengthens constraint.The further preferred scheme of the embodiment of the present application are as follows: leaned on guide axis 110 The shaft end portion of Jin Tanzhan mechanism 200 is connect with rack 700 by limiting sunpender, and the one end for limiting sunpender is connected with guide axis 110, The other end is fixed in rack 700, and limit sunpender produces along 110 progradation of guide axis for limiting guide axis 110 in bamboo section Life is axially displaced.Its principle is: by limiting the end Joint of one end and the guide axis 110 of sunpender/be connected, the other end It is fixed in rack 700, to achieve the purpose that further to constrain the axial freedom of guide axis 110, and then effectively prevent Guide axis 110 occurs axially displaced during the delivery of bamboo section.

It certainly, can also be by by wedge block 410 if wedge block 410 and the connection structure of guide axis 110 are sufficiently stable It is fixed on the rack, achievees the purpose that fixed guide axis 110, as long as can guarantee that guide axis 110 can be tied in use Structure is firm.

When bamboo section to be attached on guide axis 110, is quickly positioned, can led in order to the cutting seam to bamboo section Expect to be extended positioning protrusion on the upside of 110 head end outer surface of axis, alternatively, convex is arranged on the upside of 120 head end inner surface of shell It rises, quickly to be positioned to bamboo section, is conducive to the rapid material-feeding of bamboo section.

In order to enable the bamboo clappers after the exhibition of booth to keep form during transportation, and can natural cooling setting, this Shen It please the preferred scheme of embodiment are as follows: as shown in Figures 1 to 4, setting conveying mechanism 300 includes arranging shape along the moving direction of bamboo clappers The several groups conveying rolls being arranged in rack 700, conveying rolls are made of the conveying roller 310 of corresponding arrangement up and down, upper and lower sides Conveying roller 310 be rotatably installed in rack 700, the length direction of bamboo section in the axial direction of conveying roller 310 and material guide mechanism 100 Unanimously, the conveying roller 310 of rotation upside and/or downside drives bamboo clappers mobile, and the roll surface of the conveying roller 310 of upper and lower sides is and bamboo clappers Plate face contact.Its principle is: by conveying between referring to bamboo clappers from the conveying roller 310 of the corresponding arrangement of two rows, being conducive to bamboo Plate keeps form during transportation, and during transportation, since there are gaps between conveying roller 310, is conducive to bamboo clappers Heat dissipation and cooling, and then bamboo clappers is enable to shape.

Referring to Fig. 2, in order to which conveying rolls can adapt to the conveying of the bamboo clappers of different-thickness, the present embodiment is preferably implemented Example be, positioned at upside conveying roller 310 along plummet direction floating mount in rack 700;Conveying roller 310 positioned at downside is along lead Hammer direction is installed in rack 700.Its principle is: by the way that the conveying roller 310 of downside to be installed in along plummet direction In rack 700, by the conveying roller 310 of upside along plummet direction floating mount, thus between the roll surface of the conveying roller 310 of upper and lower sides Spacing can be adjusted according to the thickness adaptability of bamboo clappers, with achieve the purpose that adapt to different-thickness bamboo clappers conveying.
