Description

Technical Field

[0001] The present invention belongs to the technical field of automatic material conveying equipment. Specifically, it particularly relates to a veneer gluing and conveying device for plywood. Background Art

[0002] As one of the three core materials of wood-based panels, plywood occupies an important position in the fields of architectural decoration, furniture manufacturing, and logistics packaging due to its excellent processing performance. With the upgrading of downstream industries, the market has put forward higher standards for the automation level and product consistency of plywood production. Among them, the quality control of the gluing process is particularly crucial - the uniformity of the glue layer directly determines the bonding strength and service life of the board. To meet this demand, the patent CN104477594B developed an integrated gluing and conveying system. Through the coordinated operation of a moisture content detection module, an intelligent lifting platform, a multi-directional conveying mechanism, and a debris recycling device, the production yield and operation efficiency have been significantly improved.

[0003] However, it is found in actual applications that the device has obvious limitations in the processing of ultra-thin veneers (0.4 - 10 mm): First, the rotary material taking mechanism is likely to cause structural damage to large-sized thin boards during the transfer process; second, the existing separation limiting mechanism is difficult to effectively overcome the interlayer friction force, often causing secondary problems such as laminated board adhesion or positioning deviation. These technical bottlenecks urgently need to be broken through by new material processing solutions. Summary of the Invention

Detailed implementation mode

[0021] The present invention will be further described below with reference to the accompanying drawings: In the paragraphs of the detailed description, the orientation nouns involved are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] As Figures 1 to 8As shown in the figure, a glue - coating conveying device for plywood veneers includes a first frame 1, with a feeding mechanism 2 and a stuffing mechanism 3 fixedly connected in sequence at one end, and a separating mechanism 4 is fixedly installed on the top of the first frame 1. The separating mechanism 4 includes side rails 40, a negative - pressure assembly 41, an air pump 42, and a first driving mechanism 43. A plurality of side rails 40 are provided and symmetrically fixed on the top of the first frame 1, and a rotatable rotary belt 401 is embedded on one side thereof; A plurality of negative - pressure assemblies 41 are provided and arranged in sequence between the side rails 40. Both ends of the negative - pressure assembly 41 are respectively fixedly connected to the rotary belts 401 arranged in the side rails 40 on both sides, and the end portion protrudes to the other side of the rotary belt 401; At least one air pump 42 is fixedly installed in the first frame 1, and the air pump 42 is fixedly connected to the outer wall of the side rail 40 and protrudes to the other side of the side rail 40, and is intermittently communicated with the negative - pressure assembly 41; The first driving mechanism 43 is fixedly installed in the first frame 1 and is rotationally connected to the separating mechanism 4. In this way, before the glue - coating operation, a pallet carrying a board is placed on the top of the stuffing mechanism 3 by using a forklift or other transfer tools. The stuffing mechanism 3 automatically pushes the pallet to the top of the feeding mechanism 2. The feeding mechanism 2 jacks up the board, and the separating mechanism 4 separates the boards one by one; During the process of the feeding mechanism 2 jacking up, boards can be transported to the top of the stuffing mechanism 3 again for the next stuffing operation. When the feeding mechanism 2 completes the feeding work and resets, the stuffing mechanism 3 pushes the board into the feeding mechanism 2 again. At the same time, a new pallet ejects the previous pallet out of the feeding mechanism 2. When the negative - pressure assembly 41 moves to the position near the bottom edge of the side rail 40 following the rotary belt 401, the negative - pressure assembly 41 is communicated with the air pump 42, causing the negative - pressure assembly 41 to generate suction, adsorbing one end of the board and driving the board to move. As the rotary belt 401 rotates, the negative - pressure assembly 41 adsorbs the boards in sequence until the boards are completely separated from the stack of materials, and the adsorbed boards are transported to the next working area. This method of gradually separating from one end of the board can effectively reduce the air - pressure difference generated during the separation of the boards compared with the traditional overall - separation method, protecting the boards and making it less likely for the boards to suffer structural damage during the separation process.

[0023] Optionally, a plurality of fixing through - holes 401A for fixing the negative - pressure assembly 41 are provided on the surface of the rotary belt 401.

[0024] Optionally, equidistantly arranged teeth 401B are provided on the inner wall of the rotary belt 401.

[0025] Optionally, the rotary belt 401 is made of a flexible material, including but not limited to rubber, etc.

[0026] As Figure 3As shown in the figure, the first driving mechanism 43 includes a first driving machine 431, a transfer seat 432, a first connecting wheel 433, a second connecting wheel 434, and a tensioning wheel 435. The first driving machine 431 is fixedly connected to the first frame 1, and a driving pulley 4311 is fixed on its power output end. The transfer seat 432 is fixedly connected to the first frame 1, is on the same straight line as the driving pulley 4311, and a transmission belt 436 is connected between the two. The first connecting wheel 433 and the second connecting wheel 434 are respectively fixedly connected to one end of the rotary brushes 512 provided on the first dust removal assembly 51 and the second dust removal assembly 52. The tensioning wheel 435 is arranged on one side of the first connecting wheel 433 and the second connecting wheel 434 and is movably connected to the first frame. Among them, the transfer seat 432, the first connecting wheel 433, the second connecting wheel 434, and the tensioning wheel 435 are connected by the transmission belt 436.

[0027] Optionally, transmission wheel groups 4321 are provided in series on the inner side and the outer wall of the transfer seat 432.

[0028] Optionally, the first driving machine 431 is rotationally connected to the compound driving wheel 403A through the transmission belt 436.

[0029] Optionally, the type of the transmission belt 436 includes but is not limited to synchronous belts, etc.; the types of the driving pulley 4311, the first connecting wheel 433, the second connecting wheel 434, the tensioning wheel 435, and the transmission wheel groups include but are not limited to synchronous wheels, etc.

[0030] Optionally, a plurality of manifolds 421 are fixed on one side of the side rail 40, and one end of the manifold 421 communicates with the other side of the side rail 40, and the other ends are gathered and fixedly connected to the air pump.

[0031] As Figures 6 to 8 shown in the figure, a first groove 402 for installing the rotary belt 401 is provided on one side of the side rail 40; and a second groove 403 is provided at one end of the first groove 402. In this way, the first groove 402 serves as the rotation space of the rotary belt 401, which can play a certain limiting role on the rotary belt 401, so that the rotary belt 401 is not easily offset during rotation to ensure the stable operation of the rotary belt 401. And the second groove 403 is used to install some components of the first driving mechanism 43.

[0032] Optionally, a convex plate 402A is provided at the edge of the first groove 402 facing the negative pressure assembly 41. In this way, through the provided convex plate 402A, a further limiting effect can be exerted on the rotary belt 401.

[0033] Optionally, a baffle 404 is provided between the convex plates 402A, and the baffle 404 is fixedly connected to the side rail 40. In this way, the rotary belt 401 can be further limited by the cover plate. At the same time, a sliding groove 404A for the movement of the negative pressure assembly 41 is defined between the baffle 404 and the convex plate 402A, so that the negative pressure assembly 41 can move stably while following the rotary belt 401.

[0034] Optionally, the width of the first groove body 402 is smaller than the width of the rotary belt 401. In this way, through a certain width difference, it can be ensured that the rotary belt 401 maintains sealing with the second groove body 403 during the rotation in the first groove body 402, so as to ensure that the second groove body 403 can generate a certain negative pressure through the air pump 42, enabling the negative pressure assembly 41 to generate sufficient negative pressure attraction.

[0035] Optionally, arc surfaces are provided at the mouth edge of the first groove body 402 and the edge position of the convex plate 402A. In this way, through the provided arc surfaces, compared with right angles, it can effectively avoid scratching of the rotary belt 401 when the mouth edge of the first groove body 402 and the edge of the convex plate 402A come into contact with the rotary belt 401, not only improving the rotation smoothness of the rotary belt 401, but also increasing the service life of the rotary belt 401.

[0036] As Figures 6 to 8 shown, a negative pressure groove 4021 is provided at a position close to the bottom edge of the first groove body 402, and the negative pressure groove 4021 is communicated with the air pump 42. In this way, under the sealing action of the rotary belt 401, a closed space is formed in the negative pressure groove 4021, so as to generate sufficient negative pressure effect through the air pump 42. In addition, when the negative pressure assembly 41 rotates with the rotary belt 401 to the position of the negative pressure groove 4021, the negative pressure assembly 41 is communicated with the negative pressure cavity, enabling the negative pressure assembly 41 to continuously generate suction to adsorb the sheet material. As the rotary belt 401 rotates, the negative pressure assembly 41 finally exits the working area of the negative pressure groove 4021, and at this time the negative pressure assembly 41 no longer generates suction, causing the negative pressure assembly 41 to automatically separate from the sheet material, thus completing the separation and conveying work of the sheet material.

[0037] Optionally, a plurality of ventilation holes 4022 for connecting the air pump 42 are provided in the negative pressure groove 4021. In this way, through the plurality of ventilation holes 4022 distributed in the negative pressure groove 4021, the negative pressure generated in the negative pressure groove 4021 can be kept consistent, avoiding the phenomenon of relatively low local negative pressure in the negative pressure groove 4021.

[0038] As Figure 6 and Figure 7As shown in the figure, a composite drive wheel 403A is embedded in the second groove body 403. While the composite drive wheel 403A meshes with the rotary belt 401, it is also rotationally connected to the first drive mechanism 43. In this way, through the composite drive wheel 403A, the rotational connection with the first drive mechanism 43 can be converted into a meshing connection with the rotary belt 401. In addition, the integral structure of the composite drive wheel 403A can ensure that the rotary belt 401 can not only move synchronously with the first drive mechanism 43, but also ensure the motion stability of the composite drive wheel 403A and the rotary belt 401.

[0039] Optionally, an auxiliary wheel 403C adapted to the composite drive wheel 403A is embedded in the first groove body 402.

[0040] Optionally, a plurality of through grooves 403B are provided in the second groove body 403 for connecting the connecting members of the first drive mechanism 43. In this way, through the provided through grooves 403B, it is possible to directly connect to the first drive mechanism 43 without adding other components, which not only simplifies its mechanical structure, but also improves the connection stability between the composite drive wheel 403A and the first drive mechanism 43. In addition, through the through grooves 403B, the connecting members of the first drive mechanism 43 can be hidden to a certain extent, improving a certain degree of safety.

[0041] It can be understood that the connecting members between the first drive mechanism 43 and the composite drive wheel 403A include, but are not limited to, belts, chains, etc.

[0042] As Figure 4 shown in the figure, the negative pressure assembly 41 includes a follower tube 411 and a negative pressure plate 412. A plurality of clamping plates 411A are fixed at both ends of the follower tube 411, and the clamping plates 411A are fitted with the rotary belt 401; a plurality of negative pressure plates 412 are provided in total and are fixedly connected to the follower tube 411, and the negative pressure plates 412 communicate with the inside of the follower tube 411; wherein, a through cavity is provided inside the follower tube 411. In this way, the follower tube 411 can maintain good negative pressure passability when communicating with the negative pressure cavity through the internal through cavity. At the same time, through the clamping plates 411A at both ends of the follower tube 411, the connection stability with the rotary belt 401 can be improved, so that the follower tube 411 is not easily deflected during the process of moving along with the rotary belt 401, and the negative pressure plate 412 fixed thereto can always face the outside of the rotation trajectory, so as to be able to contact the sheet material and adsorb the sheet material while generating negative pressure suction.

[0043] Optionally, the end of the negative pressure plate 412 facing the plate is made of a flexible material, including but not limited to rubber. In this way, the end of the negative pressure plate 412 facing the plate is made of a flexible material. On the one hand, it can produce a certain deformation when the negative pressure plate 412 contacts the plate, avoiding extrusion damage to the plate caused by the negative pressure plate 412. On the other hand, the surface of individual plates may be uneven. Using the negative pressure plate 412 made of flexible material can produce a certain deformation during the adsorption process with the plate, making the negative pressure plate 412 fit better with the plate and the adsorption more stable.

[0044] As Figures 9 to 11 shown, it further includes a dust removal mechanism 5, which is fixed at one end of the separation mechanism 4 away from the feeding mechanism 2; wherein, the dust removal mechanism 5 is composed of a first dust removal component 51, a second dust removal component 52, and a suction pump 55. The two are arranged in sequence from top to bottom and are fixedly connected to the first frame 1; the suction pump 55 is fixedly connected to the first frame 1 and is communicated with the first dust removal component 51 and the second dust removal component 52. In this way, the first dust removal component 51 and the second dust removal component 52 arranged up and down can completely cover both sides of the plate surface, so as to carry out comprehensive dust removal and impurity removal work on the plate, thereby improving the processing quality of plate gluing.

[0045] Optionally, a filter box 56 is fixed at the air inlet end of the suction pump 55.

[0046] As Figure 12 shown, a plurality of dust suction ports 511 communicated with the suction pump 55 are provided in both the first dust removal component 51 and the second dust removal component 52, and a rotatable brush roller 512 is installed between the dust suction ports 511, and the brush roller 512 is rotatably connected to the first driving mechanism 43. In this way, by arranging a dust suction port 511 on both sides of the brush roller 512, an all-round dust removal adsorption force can be generated in the first dust removal component 51 and / or the second dust removal component 52, so as to effectively handle the impurities generated by the brush roller 512 cleaning the plate surface, making the impurities not easy to overflow, thereby protecting the working environment.

[0047] Optionally, limiting rings 513 fixed to the first dust removal component 51 or the second dust removal component 52 are provided at both ends of the brush roller 512, and springs 514 are fixed inside the limiting rings 513. In this way, through the cooperation of the limiting rings 513 and the springs 514, not only can the formation of the brush roller 512 be restricted, but also the brush roller 512 has an adaptive adjustment ability. On the one hand, it can be applied to plates of different thicknesses, and on the other hand, it can fit better with the surface of the plate, so as to improve the cleaning ability of the brush roller 512 on the plate surface.

[0048] As Figure 10As shown, one end of the first dust removal assembly 51 is hinged with a guide plate 53, and a buffer regulator 54 is fixed between the guide plate 53 and the first dust removal assembly 51. In this way, through the provided guide plate 53, the plate can be guided. So that the plate can accurately move between the first dust removal assembly 51 and the second dust removal assembly 52, so that both can clean the plate surface of the plate. At the same time, according to the different batch specifications of the plates, by adjusting the buffer regulator 54, the included angle between the guide plate 53 and the first dust removal assembly 51 can be adjusted, that is, the elevation angle of the guide plate 53, so as to improve the guiding accuracy and guiding efficiency of the guide plate 53.

[0049] Exemplarily, under the conveyance of the separation mechanism 4, the end of the plate in the advancing direction first contacts the guide plate 53. Affected by the arc-shaped plate surface of the guide plate 53, the advancing end of the plate deflects toward the space between the first dust removal assembly 51 and the second dust removal assembly 52 and accurately enters between the two.

[0050] As Figure 11 shown, the buffer regulator 54 includes a first connecting portion 541, a telescopic portion 542, and a second connecting portion 543. One end of the first connecting portion 541 is hinged to the first dust removal assembly 51, and the other end is fitted with and slidably connected to the telescopic portion 542, and a buffer spring body 5411 is embedded in the first connecting portion 541; one end of the second connecting portion 543 is hinged to the guide plate, and the other end is fitted with and slidably connected to the other end of the telescopic portion 542, and a fastening bolt rod movably connected to the telescopic portion 542 is provided on the outer wall of the second connecting portion 543; wherein, symmetrically arranged sliding grooves are provided on the side walls of the first connecting portion 541 and the second connecting portion 543.

[0051] As Figure 13 and Figure 14 shown, the loading mechanism 2 includes a second frame 21, a lifting assembly 22, and a second driving mechanism 23. The second frame 21 is fixedly connected to one end of the first frame 1; the lifting assembly 22 is movably arranged in the second frame 21, and part of the structure of the lifting assembly 22 overlaps with part of the structure of the separation mechanism 4 in the vertical direction; the second driving mechanism 23 is fixed at one end of the second frame 21 and is connected to the loading mechanism 2 and the filling mechanism 3. In this way, under the drive of the second driving mechanism 23, the lifting assembly 22 jacks up and moves the stack of plate materials placed on its top along the second frame 21 toward the separation mechanism 4. Since part of the lifting assembly 22 overlaps with the separation mechanism 4, when the plate is jacked up to a certain height, it can abut against the negative pressure disk 412 and be adsorbed by the negative pressure disk 412, so that the plate can be gradually separated from the stack of materials.

[0052] As Figure 15As shown, the second driving mechanism 23 includes a second driving machine 231 and a gear set 232. The gear set 232 is fixed to one end of the second frame 21, the second driving machine 231 is fixed to the end of the gear set 232 facing away from the second frame 21, and the power output end of the second driving machine 231 is connected to the gear set 232. As Figure 16 As shown, the gear set 232 includes a front plate body 2321, a driving gear 2322, a first shifting tooth 2323, a second shifting tooth 2324, a first driving gear 2325, a second driving gear 2326, a shifting tooth plate 2327, a shifting tooth motor 2328, and a rear plate body 2329. The driving gear 2322, the first driving gear 2325, and the second driving gear 2326 are distributed on one side of the front plate body 2321 in a triangular arrangement and are not connected to each other. The first shifting tooth 2323 is movably arranged between the driving gear 2322 and the first driving gear 2325 and meshes with the driving gear 2322 and the first driving gear 2325 in due course. The second shifting tooth 2324 is movably arranged between the driving gear 2322 and the second driving gear 2326 and meshes with the driving gear 2322 and the second driving gear 2326 in due course. The rear plate body 2329 is fixed to one side of the front plate body 2321 and encloses each gear.

The shifting tooth motor 2328 is fixed to one side of the rear plate body 2329 and is movably connected to the shifting tooth plate 2327. In this way, the shifting tooth motor 2328 and the shifting tooth plate 2327 cooperate with each other to drive the first shifting tooth 2323 and the second shifting tooth 2324 to move in the same direction simultaneously. When the shifting tooth plate 2327 is located in the middle of the rear plate body 2329, all the gears are in a separated state. When the shifting tooth plate 2327 moves towards one end, the first shifting tooth 2323 meshes with the driving gear 2322 and the first driving gear 2325, enabling the main driving wheel to drive the first driving gear 2325 through the first shifting tooth 2323. When the shifting tooth plate 2327 moves towards the other end, the first shifting tooth 2323 separates from the driving gear 2322 and the first driving gear 2325, and the second shifting tooth 2324 meshes with the driving gear 2322 and the second driving gear 2326, enabling the driving gear 2322 to drive the second driving gear 2326 through the second shifting tooth 2324.

[0053] Optionally, symmetric sliding through grooves 2330 are provided on the surfaces of the front plate body 2321 and the rear plate body 2329 for limiting the first shifting tooth 2323 and the second shifting tooth 2324.

[0054] Optionally, a plurality of limiting frames 2331 are provided at the edge of the sliding through groove 2330 provided on the rear plate body 2329 for limiting the shifting tooth plate 2327.

[0055] Optionally, the long side of the tooth-pushing plate 2327 is parallel to the power output end of the tooth-pushing motor 2328.

[0056] Optionally, a connecting rod 2332 is fixed to the middle of the tooth-pushing plate 2327, and the connecting rod 2332 meshes with the power output end of the tooth-pushing motor 2328.

[0057] Optionally, a limiting block 2333 is fixed to one side of the rear plate body 2329 and is slidably connected to the connecting rod 2332.

[0058] Optionally, a plurality of support columns 2334 are fixed between the front plate body 2321 and the rear plate body 2329.

[0059] Optionally, a first drive shaft 2335 is fixed to one end of the first drive gear 2325, and the first drive shaft 2335 is rotatably connected to the lifting assembly 22; a second drive shaft 2336 is fixed to one end of the second drive gear 2326, and the second drive shaft 2336 is rotatably connected to the pushing assembly 32.

[0060] As Figure 13 and Figure 14 shown, the packing mechanism 3 includes a bearing platform 31 and a pushing assembly 32. The bearing platform 31 is fixedly connected to one end of the second frame 21. The pushing assembly 32 is arranged on both sides of the bearing platform 31. One end of the pushing assembly 32 is embedded in the second frame 21 and is movably connected to the second driving mechanism 23. In this way, by arranging the pushing assemblies 32 on both sides of the bearing platform 31, the stack of sheet materials placed on the top of the bearing platform 31 can be pushed to the top of the lifting assembly 22.

[0061] Optionally, a plurality of rollers 311 are provided on the surface of the bearing platform 31. In this way, by means of the provided rollers 311, it is possible to avoid the direct contact between the tray carrying the sheet material and the surface of the bearing platform 31, reduce the friction between the tray and the surface of the bearing platform 31, not only improve the feeding efficiency, but also improve the service life of the tray.

[0062] Optionally, a one-way push rod 321 is hinged to the end of the pushing assembly 32 away from the second frame 21. In this way, when a transfer tool such as a forklift transports a material stack to the top of the bearing platform 31, the tray can push the one-way push rod 321 to rotate towards the second frame 21, without affecting the handling work of the tray. On the contrary, when the pushing assembly 32 pushes the tray, the one-way push rod 321 abuts against the tray and does not rotate.

[0063] Optionally, a plurality of support wheels 322 are provided at the bottom of the pushing assembly 32. In this way, on the one hand, the support wheels 322 can support the pushing assembly 32 and avoid the friction between the pushing assembly 32 and the ground. On the other hand, the support wheels 322 can improve the smoothness of movement of the pushing assembly 32.

[0064] Optionally, one end of the pushing component 32 is embedded in the second frame 21 and is connected with a synchronization plate 323.

[0065] Optionally, both ends of the synchronization plate 323 are connected with guide rods 324, and the guide rods 324 are fixedly connected with the second frame 21 and the first frame 1. In this way, through the provided guide rods 324, while limiting the synchronization plate 323, the guide rods 324 also support the second frame 21 and the first frame 1, thereby improving the connection stability between the first frame 1 and the second frame 21.

[0066] Optionally, the synchronization plate 323 is rotatably connected with the second drive shaft 2336.

[0067] Finally, although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments understandable to those skilled in the art.
