Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a material dividing mechanism of a pad printing machine. Background Art

[0002] Pad printing is an indirect printing technology with a concave rubber head. It has become a major method for printing and decorating the surfaces of various objects. The process is very simple: first, the design pattern is etched on the printing plate, the etching plate is coated with ink, and then most of the ink is transferred to the printed object through the silicone head. This printing technology has exquisite and detailed effects, and is very suitable for small areas, concave and convex surfaces, and other places where other printing methods are difficult to work. Therefore, pad printing machines are widely used in electrical appliances, plastics, toys, and glass lamp industries.

[0003] Traditional pad printing machines use a cylinder to drive a single rubber head to transfer the oil print on the template to the workpiece. When printing is completed, the workpiece needs to be taken away manually. When the next workpiece is placed on the placement platform of the pad printing machine manually, the rubber head can start the next printing. This manual operation method is very time-consuming and labor-intensive, and can easily lead to reduced working efficiency of the pad printing machine. Utility Model Content

[0004] In order to overcome the above disadvantages, the purpose of the utility model is to provide a material dividing mechanism for a pad printing machine.

[0006] Furthermore, the conveying component includes a vibrating loading tray for holding the product and conveying the product outward with the box opening facing downward, which can improve the loading efficiency while maintaining the consistency of the product placement direction, further improving the efficiency of pad printing.

[0007] Furthermore, the material transfer assembly includes a second translation member, a telescopic cylinder and a pad printing jig. The telescopic cylinder is connected to the second translation member through a support plate, which can enable the telescopic cylinder to move along a first direction and is used to transfer the product from the placement bin to the pad printing jig. Multiple products can be grabbed onto the pad printing jig at one time, which improves work efficiency.

[0008] Furthermore, a mounting plate is connected to the bottom of the telescopic cylinder, and a plurality of vacuum nozzles are connected to the mounting plate along a first direction. The vacuum nozzles are connected to a vacuum pump through an air pipe and can adsorb the bottom of the product box. Adsorption by the vacuum nozzle has better stability and is safer than grasping and clamping, and will not harm the product itself.

[0009] Furthermore, the pad printing jig is provided with several pad printing stations, which are arranged at intervals. The product can be snapped on the pad printing station, which can improve the stability of the product during the pad printing process and will not shake on the pad printing jig, affecting the quality of pad printing.

[0010] Furthermore, guide posts are provided between the two ends of the mounting plate and the support plate, and the mounting plate moves up and down along the guide posts, so as to prevent the mounting plate from rotating along the telescopic cylinder during the up and down movement, thereby affecting the adsorption position of the vacuum nozzle.

[0011] Furthermore, the surface roughness of the connecting plate is 0.4 μm, and the relatively smooth connecting plate can prevent the product from tipping over, being misplaced, etc. during the pushing process.

[0012] Furthermore, a second limit bar group is provided on both sides of the placement bin, and a feed port is reserved on the side of the second limit bar group close to the conveying component. The feed port is provided with a chamfer, which serves as a guide and also avoids collision between the product and the second limit bar group.

[0013] Furthermore, a vibrator is connected between the vibrating loading tray and the first conveying member, and a fixedly connected trough plate is provided above the vibrator. The product can move forward through the vibrator, which can prevent the product from piling up at the output end of the vibrating loading tray.

[0014] Furthermore, the conveying direction of the conveying component is opposite to that of the sub-packaging component. Setting the opposite conveying direction can shorten the length of the entire device, save space, and be more economical.

[0015] The beneficial effects of the utility model are:

[0016] 1.

DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0033] See attached Figure 1 To Attachment Figure 3 As shown, a material dispensing mechanism of a pad printing machine in this embodiment includes a conveying component 1, a dispensing component 2, a horizontal push component 3 and a material dispensing component 4, wherein: the conveying component 1 is arranged in parallel with the dispensing component 2, and the horizontal push component 3 is arranged at the conveying end of the conveying component 1; the conveying component 1 includes a first conveying member 11 and a first driving member 12, and first limiting bar groups 13 are respectively arranged on both sides of the first conveying member 11, and the first conveying member 11 can be a pulley, and the product 6 is conveyed by the pulley. The product 6 is transported by the first conveying member 11, and the first limiting bar groups 13 are respectively arranged on both sides of the first conveying member 11, which can prevent the product 6 from falling from the belt. The end of the first limiting bar group 13 and the end of the pulley conveying direction are spaced slightly larger than the width of the product 6, so that only one product 6 reaches the end of the pulley at a time, and the rest of the products 6 are retained between the first limiting bar groups 13, that is, only one product 6 reaches the attached pulley at a time. Figure 2 The baffle plate 15 in the middle. ( Figure 2 The X direction is the first direction, the Y direction is the second direction, and the second direction is perpendicular to the first direction)

[0034] See attached Figure 4As shown, the sub-packaging component 2 includes a second conveying member 21 and a second driving member 22. A plurality of stoppers 23 are arranged on the second conveying member 21 at intervals along the first direction. A placement bin 24 is formed between adjacent stoppers 23 for placing the product 6. A connecting plate 5 is provided at the ends of the conveying component 1 and the sub-packaging component 2. The product 6 can be moved from the conveying component 1 to the placement bin 24 through the connecting plate 5. The spacing between adjacent placement bins 24 is slightly larger than the width of the product 6, so that the product 6 can enter the placement bin 24 without being offset or misplaced in the placement bin 24. The stoppers 23 are connected to the second conveying member 21 by bolts or gluing, and the width of the stoppers 23 is the spacing between adjacent products 6.

[0035] In some embodiments, a second limiting strip set 25 is provided on both sides of the placement bin 24, and a feed port 26 is left on the side of the second limiting strip set 25 close to the conveying assembly 1, and the feed port 26 is provided with a chamfer that opens outward (not shown in the figure). The chamfer provided on the feed port 26 can guide the product 6 when it is pushed into the placement bin 24 by the push portion 32, and also avoid the collision between the product 6 and the second limiting strip set 25.

[0036] See attached Figure 5 To Attachment Figure 7 As shown, the push assembly 3 includes a first translation member 31 and a push portion 32, and the push portion 32 is connected to the first translation member 31 through a support plate 33, so that the push portion 32 can move along the second direction to transfer the product 6 from the conveying assembly 1 to the placement bin 24. The push portion 32 is located adjacent to the first translation member 31. Figure 6 When the product 6 is in the position, it can be transported from the first conveying member 11 to the baffle plate 15, and then the push portion 32 moves to the right to push the product 6 from the connecting plate 5 to the placement bin 24, that is, the attached Figure 7 When the horizontal push portion 32 moves to the left again, the next product 6 on the first conveying member 11 is sequentially conveyed to the baffle plate 15, thereby completing the next push and packing.

[0037] The material transfer assembly 4 is placed above the packaging assembly 2, and is used to transfer the products 6 in the placement bin 24 to the pad printing jig 91. The material transfer assembly 4 can complete the transfer of multiple products 6 at one time, while keeping the spacing and direction of the products 6 unchanged, and also improves the transfer efficiency.

[0038] By setting up the conveying component 1, the packaging component 2, the pushing component 3 and the material moving component 4, the product 6 can be automatically loaded, packaged and transferred, and multiple products 6 can be printed at the same time. Compared with manual placement or printing of a single product 6, the work efficiency is higher.

[0039] In some embodiments, the conveying direction of the conveying component 1 is opposite to that of the packaging component 2. When the product 6 is conveyed to the end of the first conveying member 11, the product 6 is pushed into the placement bin 24 by the action of the horizontal push portion 32, and then the second conveying member 21 rotates to provide the next vacant placement bin 24. Setting the first conveying member 11 and the second conveying member 21 in opposite conveying directions can shorten the length of the entire device, save space, and be more economical.

[0040] See attached Figure 6 As shown, in some embodiments, the surface roughness of the connecting plate 5 is 0.4 μm. The product 6 is pushed from the first conveying member 11 to the placement bin 24 on the second conveying member 21, and needs to pass through the connecting plate 5. A too rough connecting plate 5 will cause the product 6 to tip over or be misplaced during the pushing process. Therefore, even in the case of limited position, the surface of the connecting plate 5 needs to be kept smooth.

[0041] See attached Figure 8 As shown, in some embodiments, the conveying assembly 1 includes a vibrating loading tray 14 for holding the product 6 and conveying the product 6 outward with the box opening facing downward. The vibrating loading tray 14 is used for loading, which improves efficiency and maintains the consistency of the placement direction of the product 6, further improving the efficiency of pad printing.

[0042] See attached Figure 8 As shown, in some embodiments, a leveling device 7 is connected between the vibrating loading tray 14 and the first conveying member 11, and a fixedly connected material slot plate 8 is provided above the leveling device 7, and the product 6 can move forward through the leveling device 7. The leveling device 7 can prevent the product 6 from piling up at the output end of the vibrating loading tray 14.

[0043] See attached Fig. 9 As shown, in some embodiments, the material transfer assembly 4 includes a second translation member 41, a telescopic cylinder 42 and a pad printing jig 91. The telescopic cylinder 42 is connected to the second translation member 41 through a carrier plate 43, and the telescopic cylinder 42 can be moved along a first direction to transfer the product 6 from the placement bin 24 to the pad printing jig 91. The telescopic cylinder 42 moves along the first direction on the second translation member 41, and when it moves to the leftmost end, it can be directly above the second conveying member 21, that is, directly above the product 6 in the placement bin 24; when it moves to the rightmost end, it can be directly above the pad printing jig 91.

[0044] See attached Fig. 9As shown, in some embodiments, a mounting plate 44 is connected to the bottom of the telescopic cylinder 42, and a plurality of vacuum suction nozzles 45 are connected to the mounting plate 44 along a first direction. The vacuum suction nozzles 45 are connected to a vacuum pump through an air pipe and can absorb the bottom of the box of the product 6. The number of vacuum suction nozzles 45 can be the same as the number of placement bins 24 continuously arranged on the second conveying member 21. When enough products 6 are placed in the placement bins 24, the vacuum suction nozzles 45 absorb the bottom of the box of the product 6 and transfer the product 6 to the pad printing jig 91.

[0045] See attached Fig. 9 As shown, in some embodiments, guide posts 46 are provided between the two ends of the mounting plate 44 and the support plate 43, and the mounting plate 44 moves up and down along the guide posts 46. The provision of the guide posts 46 prevents the mounting plate 44 from rotating along the telescopic cylinder 42 during the up and down movement, thereby affecting the adsorption position of the vacuum nozzle 45.

[0046] See attached Fig.10 As shown, in some embodiments, the pad printing jig 91 is provided with a plurality of pad printing stations 92, and the pad printing stations 92 are arranged at intervals, and the distance between the pad printing stations 92 is the same as the interval between the plurality of pad printing silicone heads, so that in the next pad printing process of the product 6, the plurality of pad printing silicone heads can simultaneously complete pad printing on the product on the pad printing jig 91. The shape of the pad printing station 92 is consistent with the shape of the product 6, so that the product 6 can be just buckled on the pad printing station 92, and the product 6 can be buckled on the pad printing station 92. The spacing distance of the placement bin 24 can be the same as the spacing distance between the pad printing stations 92 on the pad printing jig 91, so that after the product 6 is transferred, there is no need to adjust the position.

[0047] The specific subpackaging process of the subpackaging mechanism of the utility model is:

[0048] 1. The product 6 is placed in the vibrating loading tray 14, and the product 6 is transported outward with the box opening facing downward;

[0049] 2. The vibrating loading tray 14 is connected to the leveling device 7. A material trough plate 8 is provided above the leveling device 7. The product 6 can be moved forward to the first conveying member 11 through the leveling device 7;

[0050] 3. Move the push portion 32 away from the first conveying member 11, and the product 6 is conveyed to the baffle plate 15;

[0051] 4. Use the push portion 32 to push the product 6 into the placement bin 24 along the second direction, and the second conveying member 21 continues to convey;

[0052] 5. When a plurality of products 6 are placed in the placement bin 24 of the second conveyor 21 , they are transferred to the pad printing station 92 of the pad printing jig 91 using the vacuum suction nozzle 45 on the transfer assembly.

[0053] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model.
