Description

TECHNICAL FIELD

[0001] The application relates to the technical field of door pocket processing equipment, and particularly relates to a door pocket pressing machine. BACKGROUND

[0002] The stepped door pocket generally comprises a main pocket and a secondary pocket, and the two sides of the main pocket and the secondary pocket are both provided with female tenons, the assembly of the two is achieved by inserting the upper piece of the female tenon of the secondary pocket into the tenon groove of the female tenon of the main pocket. Generally, an adhesive is also applied to the upper piece of the female tenon of the secondary pocket and / or the tenon groove of the female tenon of the main pocket.

[0003] Conventionally, the main pocket and the secondary pocket are assembled manually, but the labor intensity is too high and the efficiency is too low. Therefore, the existing technology forms a product of a door pocket automatic assembly machine.

[0004] For example, the stepped door pocket automatic assembly machine disclosed in CN110450256A, entitled "Stepped door pocket automatic assembly machine taking a veneer as a reference and a combination method thereof", comprises a machine base, a first workpiece groove on the upper part of the machine base, a main pocket placed in the first workpiece groove, a second workpiece platform located on the side of the first workpiece groove, a secondary pocket placed on the second workpiece platform, a push module located on the opposite side of the second workpiece platform and the first workpiece groove, used for pushing the secondary pocket to the main pocket to press the secondary pocket and the main pocket together, a lower pressing module installed above the first workpiece groove, comprising a movable pressing piece that can extend above the second workpiece platform and a fixed pressing piece facing the veneer of the main pocket, and an upper pressing module located at the bottom of the first workpiece groove, used for lifting the main pocket to a preset height and pressing the main pocket to keep it flat after the main pocket reaches the preset height. The stepped door pocket automatic assembly machine realizes the automatic assembly of the main pocket and the secondary pocket of the door pocket, has the advantages of saving labor cost, improving the combination forming quality and product production efficiency, etc. SUMMARY

[0005] The assembly of the main pocket and the secondary pocket needs to longitudinally limit the two to align the upper piece of the female tenon of the secondary pocket and the tenon groove of the female tenon of the main pocket, and then the upper piece of the female tenon of the secondary pocket is inserted into the tenon groove of the female tenon of the main pocket through the limitation of one side in the transverse direction and the pushing force of the other side in the transverse direction, and the assembly of the main pocket and the secondary pocket is completed through the continuous application of the pushing force of the other side. However, the main pocket and the secondary pocket have a relatively large length, and the female tenon of the main pocket and the female tenon of the secondary pocket have machining errors. In addition, the main pocket and the secondary pocket are mostly made of wood as raw material, including but not limited to solid wood, wood-based multi-layer board, wood-based shaving board, wood-based fiber board, etc. With the change of environmental temperature and humidity, the wood will deform to a certain extent during the transfer and storage, which will also cause the deviation between the size of the female tenon of the main pocket and the female tenon of the secondary pocket and the machining size, and also cause the bending deformation of the main pocket and the secondary pocket. The above situations may increase the alignment and assembly difficulty between the upper piece of the female tenon of the secondary pocket and the tenon groove of the female tenon of the main pocket.

[0006] In practice, the inventor found that the door pocket automatic assembly machine implemented with the veneer as the reference, which relies on the veneer of the main pocket and the auxiliary pocket as the reference surface to align the processing technology of the door pocket itself, reduces the height error generated in the pressing process of the main pocket and the auxiliary pocket, thereby improving the pressing success rate. However, this can only solve the assembly error caused by the bending of the longer main pocket and auxiliary pocket, and cannot solve the problem of assembly difficulty caused by the machining error or size change of the female tenon.

[0007] The door pocket pressing machine provided by the present application can overcome the problem of difficult assembly caused by bending, machining, and deformation by aligning and inserting one of the main pocket and the auxiliary pocket with the veneer as the reference and the bottom surface of the other as the reference. The present application specifically adopts the following technical solutions:

[0008] A door pocket pressing machine, comprising a rack, a feeding mechanism, a conveying mechanism, and a pressing mechanism, wherein the pressing mechanism comprises a pressing workbench, transverse abutments and transverse pressing units arranged on both sides of the pressing workbench, and a longitudinal limiting unit,

[0011] Through the above structure, the lifting component in the longitudinal limiting unit cooperates with the pressing workbench in the pressing mechanism, and in general, the approximate position of the main pocket and the auxiliary pocket in the longitudinal direction is defined by the lifting of the lifting component with the support limiting surface of the pressing workbench as the reference, in other words, the female tenon of the main pocket and the female tenon of the auxiliary pocket are roughly aligned. The fixed workbench cooperates with the floating limiting component, and in fine adjustment, the precise position of the main pocket / auxiliary pocket in the longitudinal direction is further defined by the elastic lifting of the floating limiting component with the support limiting surface of the fixed workbench (i.e. the bottom surface of the main pocket / auxiliary pocket) as the reference. The floating workbench cooperates with the fixed limiting component, and in fine adjustment, the precise position of the auxiliary pocket / main pocket in the longitudinal direction is further defined by the elastic lifting of the floating workbench with the lowest part of the fixed limiting component (i.e. the veneer of the auxiliary pocket / main pocket) as the reference. Thus, the door pocket pressing machine provided by the present application can overcome the problem of difficult assembly caused by bending, machining, and deformation.

[0012] As a preferred, the fixed limiting component comprises a first compression roller, and the floating limiting component comprises a second compression roller mounted on the mounting plate through an elastic member.

[0014] As a preferred, the door pocket pressing machine comprises a plurality of the pressing workstations and a plurality of the longitudinal limiting units, and the pressing workstations and the longitudinal limiting units are in one-to-one correspondence.

[0015] As a preferred, in the longitudinal direction, the support limiting surface of the fixed workbench is higher than the support limiting surface of the floating workbench, and the lowest position of the fixed limiting component is lower than the lowest position of the floating limiting component.

[0016] As a preferred, after the lifting component is lowered to the position, the fixed limiting component can indirectly drive the floating workbench to be pressed down, and the fixed workbench can indirectly drive the floating limiting component to be lifted up.

[0017] As a preferred, the floating workbench comprises an upper workbench plate and a lower workbench plate, and the upper workbench plate and the lower workbench plate are connected through a plurality of springs and / or spring pressing rods.

[0018] As a further preferred, the lifting of the upper workbench plate relative to the lower workbench plate in the longitudinal direction is limited by a linear bearing and a guide rod.

[0019] As a preferred, the transverse compression unit comprises a transverse compression push plate and a pair of transverse compression powers, and the pair of transverse compression powers are respectively connected through a connecting rod and a synchronous assembly.

[0020] As a further preferred, the transverse compression power is a worm gear reducer, and the synchronous assembly is a synchronous gear and rack assembly.

[0025] In summary, by aligning and inserting one of the main sleeve and the secondary sleeve based on the surface of the other, the problem of difficult assembly due to errors caused by bending, processing and deformation can be overcome.

[0026] Further, the main sleeve and the secondary sleeve are relatively long, which not only makes them prone to bending deformation, but also causes different dimensional changes at different positions in the axial direction (length direction), so that the amount of error formed at different positions in the length of the main sleeve and / or the secondary sleeve is different when the dimensional change actually occurs. In the preferred technical solution of the present application, by arranging a plurality of pressing tables and a plurality of longitudinal limiting units one-to-one, the assembly error of the main sleeve and the secondary sleeve can be segmented in the axial direction, so that the assembly of the two is more smooth, the adaptability of the equipment is stronger, and the tolerance to error is higher.

The height difference between the two can be pre-set. The pre-set height difference is the ideal distance between the upper tenon surface 510 of the main sleeve 500 and the decorative surface of the auxiliary sleeve 600.

[0061] Specifically, the lifting component 441 is a lifting cylinder, the telescopic end of which faces downward, and the mounting plate 412 is screw-connected to the telescopic end. The fixed limiting component 443, which is a first compression roller, is fixedly mounted on the mounting plate 412.

[0065] The door pocket pressing machine comprises a plurality of pressing workbenches 410 and a plurality of longitudinal limiting units 440 arranged at intervals, and the pressing workbenches 410 and the longitudinal limiting units 440 correspond one by one.

[0066] The door pocket pressing machine provided in the embodiment has the following pressing work method:

[0067] Firstly, the sub-cover 600 and the main cover 500 are respectively placed on the sub-cover loading unit 221 and the main cover loading unit 222, and the loading mechanism 200 is started to respectively convey the sub-cover 600 and the main cover 500, and to apply glue to the female tenon of the main cover 500; at the same time, the lifting mechanism 340 is in the jacking state, at this time, the conveying roller 320 is higher than the pressing workbench 410 and is in the running state.

[0068] Subsequently, the sub-cover 600 and the main cover 500 enter the conveying mechanism 300, and enter above the floating workbench 412 and the fixed workbench 411 respectively with the conveying of the conveying mechanism 300, after conveying to the position, the conveying mechanism 300 stops running and the conveying roller 320 is lowered to the pressing workbench 410, at this time, the sub-cover 600 and the main cover 500 fall on the floating workbench 412 and the fixed workbench 411 respectively with the lowering of the conveying roller 320.

[0069] Further, the lifting component 441 drives the fixed limiting component 443 and the floating limiting component 444 to lower as a whole, after lowering to the position, the fixed limiting component 443 drives the floating workbench 412 to press down indirectly through the sub-cover 600, and the fixed workbench 411 drives the floating limiting component 444 to lift indirectly through the main cover 500. In this process, the sub-cover 600 takes the surface as the reference, so as to fix the height of the surface of the sub-cover 600; the main cover 500 takes the bottom surface as the reference, so as to fix the position of the lower tenon surface 520 of the main cover 500, and to adjust the position of the upper tenon surface 510 of the main cover 500 on the basis of the ideal height difference, so as to ensure that the female tenon groove of the main cover 500 can be aligned and assembled with the female tenon upper piece of the sub-cover 600.

[0070] Further, the transverse pressing unit 430 moves towards the transverse fixed abutment 420 to push the main cover 500 to approach the sub-cover 600 until the female tenon upper piece of the main cover 500 is inserted into the female tenon groove of the sub-cover 600, and the assembly of the two is completed with the continuous pressing force of the transverse pressing unit 430.

[0071] Finally, the transverse pressing unit 430 retreats, the longitudinal limiting unit 440 retreats, and the conveying roller 320 jacks up, and the combined door cover is conveyed towards the unloading side.
