Description

Technical Field

[0001] The invention relates to the technical field of edge banding strip processing, and more specifically, to an edge banding strip printing device. Background Art

[0002] Edge banding is an auxiliary material, a plate material made of multiple components such as base material, glue, printing, etc. Edge banding is generally used in the fields of furniture boards, building materials, decoration, etc. It is often used to deal with defects on the edges of boards, repair uneven cutting edges, beautify furniture corners, etc. It can protect the edges of boards, extend the life of products, and at the same time be beautiful and improve product quality.

[0003] The traditional edge banding coloring is based on the different pattern and size requirements of the customer. It is necessary to customize embossing rollers of different sizes and patterns, and also to customize dyeing rollers of different numbers with the same sixteen colors. Therefore, the edge banding manufacturers will customize and store a huge number of embossing rollers and dyeing rollers. At the same time, they also need to customize and mix slurries of different colors, resulting in low site utilization, long production cycle, low production efficiency, and each change of pattern and color leads to a huge waste of the remaining slurry from the previous batch of orders. The excess slurry can only be treated as waste, causing pollution.

[0004] In order to solve the above technical problems, the prior art adopts the printing method to realize the coloring of the edge banding. This method saves the steps of customizing different numbers of dyeing rollers and embossing rollers, and greatly improves the production efficiency. However, in the production process, the edge banding is transported by a conveyor belt. When the edge banding is printed, it is necessary to spray the entire surface of the edge banding (the printing range is larger than the area of ​​the edge banding), which will cause excess ink to be sprayed on the conveyor belt during printing. Not only does it need to be cleaned regularly, which restricts the production efficiency, but the ink printed on the conveyor belt cannot be recycled, resulting in a waste of ink. Summary of the invention

[0005] The present invention overcomes two inconvenient shortcomings in the prior art: (1) the edge strip is transported by a conveyor belt during the printing process. Since excess ink is sprayed on the conveyor belt, it is necessary to regularly clean the ink on the conveyor belt, which restricts production efficiency; (2) the excess ink sprayed on the conveyor belt is difficult to recycle, resulting in a waste of ink; an edge strip printing device is provided, which does not require the use of a conveyor belt to transport the edge strip, that is, there is no moving medium under the edge strip, thereby eliminating the step of cleaning the conveyor belt and improving production efficiency; and during the printing process, an ink collection device can be used to recycle the ink that exceeds the range of the edge strip, which has the advantages of no pollution and no waste of ink.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solution: an edge banding strip printing device, comprising: A printer device, wherein a plurality of inkjet head groups are arranged in the printer device, and each inkjet head group includes a plurality of inkjet heads; The transport device comprises a first active roller and a second active roller arranged in parallel, and a plurality of ink jet head groups are arranged between the first active roller and the second active roller; A first driven roller is arranged on a side of the first active roller away from the second active roller, and the first driven roller and the first active roller are clamped with each other; A second driven roller is arranged on the side of the second active roller away from the first active roller; the second driven roller and the second active roller are clamped with each other; when printing, one end of the edge banding strip is clamped by the first active roller and the first driven roller, and the other end is clamped by the second active roller and the second driven roller; The ink recovery device includes a plurality of residual ink recovery containers for collecting excess ink. The plurality of residual ink recovery containers are respectively arranged below a plurality of ink nozzle groups, and a main ink barrel is correspondingly connected below each residual ink recovery container; the cross-sectional areas of the plurality of residual ink recovery containers are all larger than the printing area of ​​the ink nozzle group.

[0007] The edge banding strip in the present invention moves at the bottom of the ink jet head group under the drive of the transport device. Specifically, one end of the edge banding strip is clamped by the first active roller and the first driven roller, and the other end of the edge banding strip is clamped by the second active roller and the second driven roller. Under the rotation of the first active roller and the second active roller, the edge banding strip is driven to move, so that the edge banding strip moves under the ink jet head group. Compared with the prior art, the edge banding strip is transported by the transport belt, thereby eliminating the process of stopping the machine to clean the transport belt, thereby improving work efficiency.

[0008] When the edge band moves to the bottom of the ink nozzle group, the ink nozzle group sprays ink on the edge band. Each time the edge band passes through an ink nozzle group, it is printed with different colors. After passing through all the ink nozzle groups, the printing of the pattern on the edge band is completed. By coordinating with computer color matching software and PLC motion control, it is possible to print patterns and designs of different colors on the edge band. Compared with the existing technology, there is no need to make rollers with different patterns and dyeing, thereby improving production efficiency.

[0009] In addition, when the ink nozzle group is spraying the edge banding strip, the excess ink will be recovered by the residual ink recovery container under the ink nozzle group. The recovered residual ink will flow into the corresponding main ink barrel, thereby reducing the waste of ink and realizing the recovery and utilization of excess ink, which is environmentally friendly and pollution-free.

[0010] Preferably, the ink recovery device further comprises a subsidiary ink barrel and an ink pump, wherein the ink pump transports the ink in the main ink barrel to the corresponding subsidiary ink barrel, and the subsidiary ink barrel is connected to the corresponding ink nozzle group.

[0011] Each residual ink recovery container corresponds to a secondary ink barrel and an ink pump. The ink pump transports the ink in the main ink barrel to the corresponding secondary ink barrel, and the secondary ink barrel is connected to the corresponding ink nozzle group. This makes it possible to recover the residual ink of different colors separately, so as to achieve recycling, avoid pollution and waste of ink, and achieve zero discharge of ink.

[0012] Preferably, four inkjet heads are provided, and the four inkjet heads are respectively a black inkjet head group, a blue inkjet head group, a red inkjet head group and a yellow inkjet head group.

[0013] Black, blue, red and yellow are the four primary colors. Therefore, by cooperating with computer color matching software and PLC motion control, the black ink nozzle group, blue ink nozzle group, red ink nozzle group and yellow ink nozzle group are combined with each other to print patterns and designs of different colors on the edge banding strip.

[0014] Preferably, the first driven roller is connected to a first pushing device, and the first pushing device pushes the first driven roller to be close to the first active roller; The second driven roller is connected to the second pushing device, and the second pushing device pushes the second driven roller to be close to the second active roller.

[0015] The first pushing device and the second pushing device provide a stable clamping force for the first driven roller and the second driven roller, thereby achieving a stable clamping effect on the edge banding strip.

[0016] Preferably, a printing platform is provided below the plurality of ink nozzle groups, and a plurality of residual ink recovery containers are provided on the printing platform.

[0017] A plurality of residual ink recovery containers are arranged on the printing platform, and the printing platform and the residual ink recovery containers are integrally formed, so that the processing and installation of the residual ink recovery containers can be facilitated.

[0018] Preferably, the opening of the residual ink recovery container is rectangular, and the length direction of the residual ink recovery container is perpendicular to the moving direction of the edge sealing strip.

[0019] The rectangular residual ink recovery container can recover the residual ink ejected from multiple ink nozzles at one time.

[0020] Preferably, a plurality of proximal limit blocks arranged at intervals are provided on both sides of the printing platform in the length direction.

[0021] The proximal limit block has a spacing effect on the edge banding strips, so that when processing multiple edge banding strips, the multiple edge banding strips can be spaced apart from each other by one end.

[0022] Preferably, a first transition roller and a first flat drag plate are arranged on a side of the first driven roller away from the first active roller; A second transition roller and a second flat drag plate are arranged on a side of the second driven roller away from the second active roller; A plurality of distal limit blocks are disposed on the first flat carriage and the second flat carriage.

[0023] The far-end limiting block has a spacing effect on the edge banding strips, so that when processing multiple edge banding strips, the multiple edge banding strips can be spaced apart from each other by one end.

[0024] Preferably, the first pushing device and the second pushing device are both cylinders.

[0025] The cylinder has the characteristics of simple structure and can provide stable thrust, and provide stable clamping force for the first driven roller and the second driven roller, so as to play a stable clamping effect on the edge banding strip.

[0026] Preferably, a plurality of ink nozzle groups are provided with ink curing devices correspondingly along the moving direction of the edge banding strip; after the ink nozzle groups spray ink on the edge banding strip, the ink printed on the edge banding strip is dried when passing through the ink curing device.

[0027] The ink curing device allows the ink on the edge banding strip to dry quickly before the next printing, thereby achieving a better printing effect.

[0028] Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes the transportation of edge banding strips without a conveyor belt through the mutual cooperation of the first active roller, the first driven roller, the second active roller and the second driven roller. That is to say, when the edge banding strips are sprayed, there is no medium at the bottom of the edge banding strips to drive the movement, so that no ink will be sprayed on the conveyor belt. Compared with the prior art, the cleaning of the moving medium (conveyor belt) is omitted, thereby realizing continuous production of edge banding strips, thereby improving the production efficiency of edge banding strips.

[0029] At the same time, corresponding residual ink recovery containers are arranged at the bottom of several ink nozzle groups, so that the excess ink can be recovered and recycled, which has the advantages of no waste of ink and no pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1: Reference Figures 1 to 5 As shown, an edge strip printing device includes: The printer device 2 includes a plurality of inkjet heads, each of which includes a plurality of inkjet heads; The transport device comprises a first active roller 31 and a second active roller 32 arranged in parallel, and a plurality of inkjet head groups are arranged between the first active roller 31 and the second active roller 32; A first driven roller 311 is disposed on one side of the first active roller 31 away from the second active roller 32, and the first driven roller 311 and the first active roller 31 are clamped together; A second driven roller 321 is arranged on the side of the second active roller 32 away from the first active roller 31; the second driven roller 321 and the second active roller 32 are clamped with each other; when printing, one end of the edge banding strip 5 is clamped by the first active roller 31 and the first driven roller 311, and the other end is clamped by the second active roller 32 and the second driven roller 321; The ink recovery device 4 includes a plurality of residual ink recovery containers for collecting excess ink. The plurality of residual ink recovery containers are respectively arranged under a plurality of ink nozzle groups, and a main ink barrel 46 is correspondingly connected to the bottom of each residual ink recovery container; the cross-sectional areas of the plurality of residual ink recovery containers are all larger than the printing area of ​​the ink nozzle group.

[0038] The edge band moves under the drive of the transport device at the bottom of the ink jet head group. Specifically, one end of the edge band is clamped by the first active roller 31 and the first driven roller 311, and the other end of the edge band is clamped by the second active roller 32 and the second driven roller 321. The first active roller 31 and the second active roller 32 rotate to drive the edge band to move, so that the edge band moves under the ink jet head group. Compared with the prior art, the edge band is transported by the transport belt, thereby eliminating the process of stopping the machine to clean the transport belt, thereby improving production efficiency.

[0039] When the edge band moves under the ink nozzle group, the ink nozzle group sprays ink on the edge band. Each time the edge band passes through an ink nozzle group, different patterns are printed. After passing through all the ink nozzle groups, the pattern printing on the edge band is completed. By cooperating with computer color matching software and PLC motion control, patterns and designs of different colors can be printed. Compared with the existing technology, there is no need to make rollers with different patterns and dyeing, thereby improving production efficiency.

[0040] In addition, when the ink nozzle group sprays the edge banding strip, the excess ink will be recovered by the residual ink recovery container under the ink nozzle assembly, and the recovered residual ink will flow into the corresponding main ink barrel 46, thereby reducing the waste of ink and realizing the recovery and utilization of excess ink, which is environmentally friendly and pollution-free.

[0041] Example 2: Reference Figures 1 to 5 As shown, an edge strip printing device includes: a frame 1, a printer device 2, a transportation device and an ink recovery device 4.

[0042] The printer device 2 includes but is not limited to a digital printing device, in which a plurality of inkjet head groups are arranged, and each inkjet head group includes a plurality of inkjet heads.

[0043] The transport device comprises a first active roller 31 and a second active roller 32 which are arranged in parallel, and a plurality of inkjet head groups are arranged between the first active roller 31 and the second active roller 32 .

[0044] A first driven roller 311 is disposed on a side of the first active roller 31 away from the second active roller 32 , and the first driven roller 311 and the first active roller 31 are clamped together.

[0045] A second driven roller 321 is provided on the side of the second active roller 32 away from the first active roller 31; the second driven roller 321 and the second active roller 32 are clamped with each other; when printing, one end of the edge banding strip 5 is clamped by the first active roller 31 and the first driven roller 311, and the other end is clamped by the second active roller 32 and the second driven roller 321.

[0046] The number of inkjet heads in the inkjet head group is determined according to the number of edge banding strips actually processed. Since the first active roller 31 and the second active roller 32 are used in this embodiment to realize the transportation of the edge banding strips, multiple edge banding strips can be transported at one time, and by setting the number of inkjet heads in each inkjet head group accordingly, multiple edge banding strips can be printed at one time, thereby improving the processing efficiency of the edge banding strips. In this embodiment, taking the one-time processing of four edge banding strips as an example, each inkjet head group is correspondingly provided with four inkjet heads, and the four inkjet heads are distributed along the vertical direction of the movement of the edge banding strips.

[0047] The frame 1 is composed of a plurality of beam tubes. Two mounting wall panels 11 are provided at both ends of the length direction of the frame 1. A cross beam plate 12 is provided on the top of the frame 1, and the printer device 2 is provided above the cross beam plate 12. The first active roller 31 and the second active roller 32 are provided on both sides of the cross beam plate 12 in the length direction.

[0048] In one embodiment, the first active roller 31, the first driven roller 311, the second active roller 32 and the second driven roller 321 are rotatably disposed at two corresponding mounting wall panels 11. The first active roller 31 is connected to the output end of the first rotating motor 33, and the second active roller 32 is connected to the output end of the second rotating motor 34. The first rotating motor 33 and the second rotating motor 34 drive the first active roller 31 and the second active roller 32 to rotate respectively.

[0049] The first driven roller 311 is connected to the first pushing device 35, and the first pushing device 35 pushes the first driven roller 311 toward the first active roller 31, so that the first driven roller 311 and the first active roller 31 are clamped with each other, and the edge banding strip passes between the first active roller 31 and the first driven roller 311, thereby clamping the edge banding strip.

[0050] The second driven roller 321 is connected to the second pushing device 36, and the second pushing device 36 pushes the second driven roller 321 toward the second active roller 32, so that the second driven roller 321 and the second active roller 32 are clamped with each other, and the edge banding strip passes between the second active roller 32 and the second driven roller 321, thereby clamping the edge banding strip.

[0051] The first pushing device 35 and the second pushing device 36 in this embodiment have the same structure, and both use cylinders. That is, a cylinder is provided at both ends of the first driven roller 311 and the second driven roller 321. That is, a cylinder is connected to each end of the first driven roller 311, and the two cylinders simultaneously push the first driven roller 311 toward the direction of the first active roller 31, and the two cylinders act simultaneously to provide a stable clamping force. A cylinder is also connected to each end of the second driven roller 321, and the two cylinders simultaneously push the second driven roller 321 toward the second active roller 32, and the two cylinders act simultaneously to provide a stable clamping force.

[0052] The edge banding strip is driven by the transport device to move at the bottom of the ink jet head group. Specifically, one end of the edge banding strip is clamped by the first active roller 31 and the first driven roller 311, and the other end of the edge banding strip is clamped by the second active roller 32 and the second driven roller 321. The edge banding strip is driven to move under the ink jet head group by the rotation of the first active roller 31 and the second active roller 32. Compared with the prior art, the edge banding strip is transported by the transport belt, thereby eliminating the process of stopping the machine to clean the transport belt, thereby improving the production efficiency of the edge banding strip.

[0053] The ink recovery device 4 includes a plurality of residual ink recovery containers for collecting excess ink, and the plurality of residual ink recovery containers are respectively arranged under the plurality of ink nozzle groups, and a main ink barrel 46 is correspondingly connected to the bottom of each residual ink recovery container; the cross-sectional areas of the plurality of residual ink recovery containers are all larger than the printing area of ​​the ink nozzle group. Since the edge strip needs to be printed on a full-width basis, the area where the ink nozzle needs to be sprayed needs to be larger than the width of the edge strip, which will cause residual ink to be sprayed from the side of the edge strip. The cross-sectional area of ​​the residual ink recovery container is larger than the printing area of ​​the ink nozzle group, and the residual ink sprayed from the ink nozzle assembly can be fully recovered.

[0054] In one embodiment, four groups of inkjet heads are provided. The four groups of inkjet heads are respectively a black inkjet head group 21, a blue inkjet head group 22, a red inkjet head group 23 and a yellow inkjet head group 24. Black, blue, red and yellow are four primary colors, so by cooperating with computer color matching software and PLC motion control, the black inkjet head group 21, the blue inkjet head group 22, the red inkjet head group 23 and the yellow inkjet head group 24 are combined with each other to print patterns and designs of different colors on the edge banding strip.

[0055] Correspondingly, four residual ink recovery containers are arranged below the four ink nozzle groups, and the four residual ink recovery containers are respectively a black residual ink recovery container 41, a blue residual ink recovery container 42, a red residual ink recovery container 43 and a yellow residual ink recovery container 44.

[0056] The ink recovery device 4 also includes a sub-ink barrel 45 and an ink pump. Each residual ink recovery container corresponds to a sub-ink barrel 45 and an ink pump. The ink pump transports the ink in the main ink barrel 46 to the corresponding sub-ink barrel 45, and the sub-ink barrel 45 is connected to the corresponding ink nozzle group. This makes it possible to recover the residual ink of different colors separately, so as to achieve recycling, avoid pollution and waste of ink, and achieve zero discharge of ink.

[0057] In one embodiment, a printing platform 6 is provided on the crossbeam plate 12, that is, the printing platform is provided below a plurality of inkjet head groups. A plurality of residual ink recovery containers are provided on the printing platform, and the printing platform and the residual ink recovery container are provided in one piece. Thus, the processing and installation of the residual ink recovery container can be facilitated. The opening of the residual ink recovery container is rectangular, and the length direction of the residual ink recovery container is perpendicular to the direction in which the edge band moves.

[0058] In one embodiment, a plurality of proximal stop blocks 37 are arranged at intervals on both sides of the length direction of the printing platform 6. Specifically, the number of proximal stop blocks 37 is set according to the edge banding. In this embodiment, four edge bands are processed at the same time as an example, so five proximal stop blocks 37 are set in this embodiment. The proximal stop blocks 37 are arranged at intervals, and a transportation channel is formed between adjacent proximal stop blocks 37, and the edge banding moves in the transportation channel. The proximal stop blocks 37 have a spacing effect on the edge banding, so that when processing multiple edge bandings, the multiple edge bandings can be spaced apart from each other by one end.

[0059] In one embodiment, a first transition roller 38 and a first flat drag plate 13 are provided on the side of the first driven roller 311 away from the first active roller 31. A second transition roller 39 and a second flat drag plate 14 are provided on the side of the second driven roller 321 away from the second active roller 32. A plurality of distal stop blocks 15 are provided on both the first flat drag plate 13 and the second flat drag plate 14. The number and function of the distal stop blocks 15 are the same as those of the proximal stop blocks 37, and they play a role in separating the multiple edge banding strips.

[0060] The working principle of this embodiment is as follows: the four edge banding strips pass through the first flat carriage 13 and the first transition roller 38 in sequence, then pass through the bottom of the first driven roller 311, and then pass through between the first driven roller 311 and the first active roller 31, and the edge banding strips are clamped by the first active roller 31 and the first driven roller 311, and then the edge banding strips pass from above the first active roller 31, and then pass through the bottom of the black ink nozzle group 21, the blue ink nozzle group 22, the red ink nozzle group 23 and the yellow ink nozzle group 24 in sequence, and then pass from above the second active roller 32, and then pass between the second active roller 32 and the second driven roller 321, and the edge banding strips are clamped by the second active roller 32 and the second driven roller 321, and then the edge banding strips pass from below the second driven roller 321, and then pass from the second transition roller 39 and the top of the first flat carriage 13.

[0061] By controlling the rotation of the first active roller 31 and the second active roller 32, the edge banding strip can move under the black ink nozzle group 21, the blue ink nozzle group 22, the red ink nozzle group 23 and the yellow ink nozzle group 24, and the edge banding strip is printed by the black ink nozzle group 21, the blue ink nozzle group 22, the red ink nozzle group 23 and the yellow ink nozzle group 24. The black ink nozzle group 21, the blue ink nozzle group 22, the red ink nozzle group 23 and the yellow ink nozzle group 24 are controlled by computer color adjustment software to realize printing of patterns of various colors and styles.

[0062] During the printing process, the excess ink sprayed is recovered by the respective residual ink recovery containers, and the recovered residual ink falls into the main ink barrel 46. Then, the ink in the main ink barrel 46 is transported to the auxiliary ink barrel 45 through the ink pump. The ink nozzle group is connected to the auxiliary ink barrel 45, and then the ink is sprayed out from the ink nozzle group to realize the recovery and utilization of the excess ink.

[0063] The present invention realizes the transportation of edge banding strips without a conveyor belt through the mutual cooperation of the first active roller 31, the first driven roller 311, the second active roller 32, and the second driven roller 321. That is, when the edge banding strips are sprayed, there is no medium at the bottom of the edge banding strips to drive it to move, so that no ink will be sprayed on the conveyor belt. Compared with the prior art, the cleaning of the moving medium (conveyor belt) is omitted, thereby realizing continuous production of edge banding strips, thereby improving the production efficiency of edge banding strips.

[0064] At the same time, corresponding residual ink recovery containers are arranged at the bottom of several ink nozzle groups, so that the excess ink can be recovered and recycled, which has the advantages of no waste of ink and no pollution.

[0065] Example 3: Figure 6As shown, the structure of this embodiment is similar to that of the embodiment 2, except that a plurality of inkjet head groups are provided with ink curing devices 7 correspondingly along the direction of movement of the edge banding strip; after the inkjet head groups spray ink on the edge banding strip, the ink on the edge banding strip is cured and dried when passing through the ink curing device. That is, the black inkjet head group 21, the blue inkjet head group 22, the red inkjet head group 23 and the yellow inkjet head group 24 are each provided with a black ink curing device 71, a blue ink curing device 72, a red ink curing device 73 and a yellow ink curing device 74 correspondingly. The ink curing device in this embodiment uses a UV lamp, which includes an LED lamp and a mercury lamp, but the ink curing device includes but is not limited to a UV lamp.

[0066] The black ink curing device 71, the blue ink curing device 72, the red ink curing device 73 and the yellow ink curing device 74 enable the ink on the edge banding strip to dry quickly before the next printing, thereby achieving a better printing effect.
