Description
Technical Field
[0001] This application relates to the technical field of printing equipment, and particularly to an automatic printing equipment for safety helmets. Background Art
[0002] After the plastic safety helmets are formed, some special words or patterns need to be printed on them. For example, on the construction sites of building construction, the name and logo of the construction unit need to be printed above the brim of the safety helmets of the unified standard type, which is convenient for quickly identifying and uniformly managing the construction personnel on the construction site.
[0003] In the actual processing of safety helmets with printing requirements, most operators hold the printing module to dip the dye solution in the dye solution box. Then, press the printing module dipped with the dye solution on the safety helmet. At this time, the safety helmet is mostly held by the operator to form the words and / or graphics on the printing module on the safety helmet.
[0004] However, when operators manually print on safety helmets, there is a problem of low operation efficiency; moreover, since the safety helmets are not positioned during manual printing, most operators print on the safety helmets by feeling or experience, so it is easy to have the problem that the printed signs are in different positions on different safety helmets; in addition, there may also be problems that the printed contents on different batches of safety helmets are of different shades and the clarity is good or bad, and the printing quality is difficult to guarantee; therefore, improvement is needed. Summary of the Invention
[0005] Object of the Invention: This application provides an automatic printing equipment for safety helmets, aiming to improve the technical problems of low printing efficiency on safety helmets by manpower, non-uniform positions of the printed signs, and difficult guarantee of printing quality control.
[0006] Technical Solution: This application provides an automatic printing equipment for safety helmets, including: a cap fixing device for placing the cap body and capable of fixing the position of the cap body; a base, on which a dye solution tray for storing the dye solution is arranged in a direction inclined towards the cap fixing device; a support plate is arranged on one side of the base where the dye solution tray is located, and a printing device is arranged on the support plate; the printing device includes an adjustment mechanism parallel to the dye solution tray, and a printing mechanism arranged on the adjustment mechanism and capable of being controlled to move by the adjustment mechanism; when the adjustment mechanism controls the printing mechanism to stay at the first dropping point, the printing mechanism can dip the dye solution in the dye solution tray; when the adjustment mechanism controls the printing mechanism to drop at the second dropping point, the printing mechanism can print on the cap body fixed on the cap fixing device.
[0007] By adopting the above technical scheme, the cap body can be positioned quickly and stably through the cap fixing device, so that the cap body can be fixed in a specific position, and the problem of movement and swaying of the cap body during the printing process is effectively reduced; the printing mechanism performs fixed-point printing on the positioned cap body at the second landing point, which helps to ensure the uniformity of the printing position and printing clarity of the printing mechanism on the cap body; the positioning mechanism controls the printing mechanism to move back and forth between the first landing point and the second landing point to realize the separate operations of dye dipping and cap body printing, which can not only ensure the continuity and stability of the cap body printing, but also ensure that the printing mechanism always has enough dye to print clearly on the cap body.
[0008] Furthermore, the cap fixing device includes a base frame and a cap mold arranged on the base frame; the cap mold is located below the dye liquid material tray, and the cap body can be fitted on the cap mold to be positioned on the cap mold; the positioning mechanism is a linear motor, and the positioning mechanism includes a positioning host arranged at one end of the support plate away from the base and parallel to the dye liquid material tray, and a moving end movably arranged on the positioning host; the printing mechanism includes a plurality of groups of telescopic parts arranged in an array on the moving end, a connecting plate arranged on the output ends of all the telescopic parts, a plurality of groups of mounting parts arranged in an array on the connecting plate, and a printing soft mold arranged on the mounting part and capable of deformation; wherein the telescopic part is an electric cylinder; when the moving end stays at the first landing position, the output end of the telescopic part can extend outward by a first stroke length, so that the printing soft mold moves to the dye liquid material tray to be contaminated with dye; when the moving end stays at the second landing position, the output end of the telescopic part can extend outward by a second stroke length, so that the printing soft mold can print the cap body positioned on the cap mold.
[0009] By adopting the above technical solution, when the moving end moves to the first landing position, the telescopic part can extend the output end to the first stroke length, so that the printing soft mold can dip the dye into the dye material tray; when the moving end moves to the second landing position, the telescopic part can extend the output end to the second stroke length, so that the printing soft mold can be printed on the cap mold that has been positioned; this process realizes the separate operations of dye dipping and printing and the standardized process operations, and under the background that the cap body has been positioned, it can effectively ensure the position accuracy and clarity of the printing soft mold on the cap body.
[0010] Furthermore, the mounting member is an I-shaped steel block, and a dovetail-shaped clearance channel is provided through the mounting member; a mounting strip is adapted and inserted into the side wall of the clearance channel, and the printed soft mold is arranged on the bottom wall of the mounting strip.
[0011] By adopting the above technical solution, the mounting bar is inserted in the clearance channel to be quickly and stably positioned on the mounting part, and the printing soft mold is fixed on the bottom wall of the mounting bar, thereby realizing the rapid installation and positioning of the printing soft mold on the mounting part; in addition, the mounting bar can also be slid out of the clearance channel to realize rapid disassembly on the mounting part.
[0012] Furthermore, the printing mechanism also includes a guide rod arranged on the mounting member; the guide rod is L-shaped, one end of the guide rod is slidably connected to an extension tube, the end of the extension tube away from the guide rod is provided with a hose that can be bent and deformed, and the end of the hose away from the extension tube is provided with a hot air blower that can blow hot air to the part of the cap body to be printed.
[0013] By adopting the above technical scheme, the extension tube can adjust the distance between the hot air blower and the cap body by sliding on the guide rod, and the hose can make the blowing port of the hot air blower close to and toward the part to be printed on the cap body after bending and deformation; after the hot air blower blows hot air to the part to be printed on the cap body, the part to be printed on the cap body can be heated and heated, which helps to make the mark printed by the printing soft mold on the cap body clearer and more stable in forming, thereby improving the printing quality of the printing device on the cap body.
[0014] Furthermore, the printing device also includes a liquid guiding mechanism, which includes a plurality of groups of pushing members arranged on the moving end and located on one side of all the telescopic members, and a guide plate arranged on the output ends of all the pushing members; the pushing member is an electric cylinder; the guide plate is provided with a plurality of groups of bottom boxes in an array facing the side wall of the dye liquid material tray, and each group of the bottom boxes is rotatably provided with a soft and deformable liquid guiding roller; in the process of the moving end moving from the first landing position to the second landing position, the liquid guiding roller is always located above the dye liquid material tray; after the moving end is positioned at the second landing position, the pushing member extends the output end to make the liquid guiding roller abut against the dye liquid material tray to be stained with dye; in the process of the moving end moving from the second landing position to the first landing position, the liquid guiding roller moves by compression deformation to drive the dye to move in the dye liquid material tray; after the moving end returns to the first landing position, the pushing member contracts the output end to move the liquid guiding roller above the dye liquid material tray.
[0015] By adopting the above technical solution, when the first mobile end is located at the first landing point and just moves to the second landing point, the liquid guide soft roller is always above the dye liquid tray; before the outer extension output end of the telescopic member, the outer extension output end of the pushing member makes the liquid guide soft roller enter the dye liquid tray and soak in the dye liquid; after the printing soft mold finishes printing on the cap body, during the process of the first mobile end returning from the second landing point to the first landing point, the liquid guide soft roller can move along with the first mobile end. The moving liquid guide soft roller reduces the contact with the inner wall of the dye liquid tray through compressive deformation, and can evenly push the dye liquid from the bottom of the dye liquid tray to the middle of the dye liquid tray during the moving process; then, after the first mobile end returns to the first landing point, the pushing member contracts the output end and makes the liquid guide soft roller move above the dye liquid tray, and the dye liquid that has moved to the middle of the dye liquid tray can flow back to the bottom of the dye liquid tray under the action of gravity; during this process, the dye liquid realizes movement and convergence, and can make the coloring substances in the dye liquid evenly distributed in each layer of the dye liquid, which helps to reduce the problem that the coloring substances in the dye liquid settle at the bottom of the dye liquid due to the long-term accumulation of the dye liquid at the bottom of the dye liquid tray, and further causes unclear printing when the printing soft mold dips the dye liquid and prints on the cap body.
[0016] Further, the cap fixing device further includes a transposition mechanism for moving the cap mold. The transposition mechanism is a linear motor. The transposition mechanism includes a transposition main body parallel to the connecting plate, and a second mobile end movably arranged on the transposition main body; the chassis is fixed on the second mobile end; when adjacent printing soft molds are printing soft molds with different printing patterns, the second mobile end can move along the length direction of the transposition main body between two outer extension second stroke lengths of the telescopic member, so that the printing soft molds with different printing patterns can respectively print on the cap body.
[0017] By adopting the above technical solution, the second mobile end moves along the length direction of the transposition main body on the transposition main body, so that the cap mold can stay under different printing soft molds, thereby facilitating the printing of the cap mold by the printing soft molds with different patterns respectively to form a combination of characters and / or patterns that meet the production requirements on the cap mold.
[0018] Further, the chassis includes a bottom plate fixed on the second mobile end. A support plate is rotatably arranged on the bottom plate, and a side plate is fixedly arranged on the side wall of the support plate. A reversing cylinder is rotatably arranged on the top wall of the second mobile end and on one side of the bottom plate. The output end of the reversing cylinder is rotatably connected to the side plate. A push cap cylinder is also fixedly arranged on the side wall of the support plate and above the side plate. The output end of the push cap cylinder passes through the support plate and is fixedly connected to the cap mold. A baffle is further fixedly arranged on the top wall of the second mobile end and on the side of the bottom plate away from the push cap cylinder. After the reversing cylinder extends its output end, the support plate can be rotated towards the direction close to the baffle. After the push cap cylinder extends its output end, the cap mold can be moved towards the baffle, and the cap body can be abutted between the cap mold and the baffle.
[0019] By adopting the above technical solution, the cap body to be printed can be initially positioned after being sleeved on the cap mold. Then, the reversing cylinder extends its output end to push the side plate, so that the support plate rotates towards the direction close to the baffle, and thus the cap mold and the cap body can be close to the baffle and face the baffle. Next, the push cap cylinder extends its output end, so that the cap mold and the cap body move towards the baffle until the cap body is tightly abutted against the baffle. At this time, the abutting block is compressed by force and abuts tightly between the cap body and the baffle, and the cap body can be tightly abutted between the cap mold and the baffle, and the position of the cap body is stably fixed, effectively reducing the problem of printing misalignment caused by the movement and deflection of the cap body during the printing process.
[0020] Further, a flexible and deformable abutting block is also arranged on the side wall of the baffle facing the cap mold, and the abutting block can abut tightly between the baffle and the cap body.
[0021] By adopting the above technical solution, the abutting block can be stressed and compressed and deformed during the process of the cap body and the baffle approaching each other. After being compressed, the abutting block compresses and deforms to abut tightly between the cap body and the baffle, which helps to ensure the position stability of the cap body on the cap mold.
[0022] In summary, the present application has at least the following beneficial technical effects: The cap body can be quickly and stably positioned through the cap fixing device, so that the cap body can be fixed at a specific position, and effectively reduces the problems of movement and deflection of the cap body during the printing process. The printing mechanism performs fixed-point printing on the already positioned cap body at the second landing point, which helps to ensure the unity of the printing position and the printing clarity on the cap body. The position adjustment mechanism controls the printing mechanism to reciprocate between the first landing point and the second landing point to realize the separate operations of dye dipping and cap body printing, which can not only ensure the continuity and stability of cap body printing, but also ensure that the printing mechanism always has enough dye to clearly print on the cap body. When the mobile unit 1 is at the first landing point and when the mobile unit 1 just moves to the second landing point, the liquid guiding soft roller is always located above the dye solution tray; before the telescopic member extends the output end, the pushing member extends the output end to make the liquid guiding soft roller enter the dye solution tray and soak in the dye solution; after the printing soft mold finishes printing on the cap body, during the process of the mobile unit 1 returning from the second landing point to the first landing point, the liquid guiding soft roller can move following the mobile unit 1. The moving liquid guiding soft roller reduces the contact with the inner wall of the dye solution tray through compression deformation, and can evenly push the dye solution from the bottom of the dye solution tray to the middle of the dye solution tray during the moving process; then, after the mobile unit 1 returns to the first landing point, the pushing member contracts the output end and makes the liquid guiding soft roller move above the dye solution tray, and the dye solution that has moved to the middle of the dye solution tray can flow back to the bottom of the dye solution tray under the action of gravity; during this process, the dye solution realizes movement and convergence, which can make the coloring substances in the dye solution evenly distributed in each layer of the dye solution, helping to reduce the problem that the coloring substances in the dye solution settle at the bottom of the dye solution tray due to the long-term accumulation of the dye solution at the bottom of the dye solution tray, and resulting in unclear printing when the printing soft mold dips the dye solution and prints on the cap body.

[0025] The embodiment of the present application discloses an automatic printing device for safety helmets.
[0026] The following is combined with Figure 1-6 This application is described in further detail.
[0027] Embodiment 1 Reference Figure 1 The invention discloses an automatic printing device for a safety helmet, which is used for positioning a helmet body and can automatically print the positioned helmet body.
[0028] Reference Figure 1 Specifically, the automatic helmet printing device includes a cap fixing device, which includes a base frame 1, a cap mold 2 and a transposition mechanism 3. The cap mold 2 is installed on the transposition mechanism 3 through the base frame 1.
[0029] Reference Figure 2 In this embodiment, the transposition mechanism 3 can be a linear motor. The transposition mechanism 3 includes a transposition host 31 and a second moving end 32, wherein the transposition host 31 is fixed to the top of the H-shaped steel frame by bolts, and the H-shaped steel frame can be directly placed on the ground, so that the transposition host 31 can be quickly and stably positioned above the ground.
[0030] Reference Figure 2 The second mobile terminal 32 is movably arranged on the transposition host 31. The second mobile terminal 32 can reciprocate along the length direction of the transposition host 31, and the second mobile terminal 32 can stop at any position of its moving path.
[0031] Reference Figure 2, the chassis 1 is arranged on the top wall of the second mobile end 32. The chassis 1 includes a bottom plate 11. In this embodiment, the bottom plate 11 can be a rectangular solid steel plate, and the bottom plate 11 is welded to the top wall of the second mobile end 32. A support plate 12 is rotatably arranged on the top wall of the bottom plate 11 through a rotating shaft. The support plate 12 is also a rectangular solid steel plate. A side plate 13 is perpendicularly welded to the side wall on one side in the width direction of the support plate 12.
[0032] Refer to Figure 2 , on the top wall of the second mobile end 32 and on one side of the bottom plate 11, a reversing cylinder 321 is rotatably arranged through a rotating shaft. The output end of the reversing cylinder 321 is close to the end of the side plate 13 away from the support plate 12, and the two are rotatably connected through a rotating shaft. In this embodiment, when the output end of the reversing cylinder 321 is in a contracted state, the included angle between the support plate 12 and the bottom plate 11 is about 60°; when the output end of the reversing cylinder 321 extends, the output end of the reversing cylinder 321 can push the side plate 13 and the support plate 12 to move along the extending direction, and then the support plate 12 can rotate on the bottom plate 11, and the included angle between the support plate 12 and the bottom plate 11 is expanded to about 80°.
[0033] Refer to Figure 2 , a push cap cylinder 121 is also fixed to the side wall of the support plate 12 on the side where the side plate 13 is arranged through bolts. The push cap cylinder 121 is located above the side plate 13, and the output end of the push cap cylinder 121 passes through the support plate 12. The cap mold 2 is welded to the end wall in the length direction of the output end of the push cap cylinder 121. In this embodiment, the outer peripheral dimension of the cap mold 2 is adapted to the cap body. The cap body to be printed can be sleeved on the cap mold 2 with a size fit. Since the shape of the cap body coincides with that of the cap mold 2, the convenience and position stability of sleeving the cap body on the cap mold 2 can be ensured, which helps to reduce problems such as movement and deviation of the cap body during printing.
[0034] Refer to Figure 2 , in order to improve the position stability of the cap body on the cap mold 2, a baffle 322 is also welded to the top wall of the second mobile end 32. The baffle 322 is located at the end of the cap mold 2 away from the push cap cylinder 121, and there is a gap between the cap mold 2 and the baffle 322 when the output end of the push cap cylinder 121 is in a contracted state. An abutting block 323 is also fixed to the side wall of the baffle 322 facing the cap mold 2 through glue. In this embodiment, the abutting block 323 can be a flexible and easily deformable rubber block.
[0035] After the cap body to be printed is sleeved on the cap mold 2, it can be preliminarily positioned. Then, the outer extending output end of the reversing cylinder 321 pushes the side plate 13, causing the supporting plate 12 to rotate towards the baffle 322, so that the cap mold 2 and the cap body approach the baffle 322 and face the baffle 322. Next, the outer extending output end of the cap pushing cylinder 121 moves the cap mold 2 and the cap body towards the baffle 322 until the cap body abuts tightly against the baffle 322. At this time, the abutting block 323 is compressed by the force and abuts tightly between the cap body and the baffle 322, and the cap body can be tightly held between the cap mold 2 and the baffle 322, and the position of the cap body is stably fixed, effectively reducing the problem of printing misalignment caused by the movement and deflection of the cap body during the printing process. In addition, the second mobile end 32 can reciprocate along the length direction of the transposition main machine 31 and stop at any position on its movement path, so that the cap body can receive printing with different die prints at different positions.
[0036] Referring to Figure 1 , in order to automatically and accurately print the cap body, the automatic safety cap printing equipment further includes a base 4. In this embodiment, the base 4 can be a rectangular operating table, the base 4 is placed on the ground, the base 4 is located on one side of the transposition main machine 31 in the width direction, and the top wall of the base 4 is located above the top wall of the cap mold 2.
[0037] Referring to Figure 1 , a dye solution tray 41 is obliquely arranged on the top wall of the base 4. In this embodiment, the dye solution tray 41 is a dye solution box with a plurality of independent spaces, and different independent spaces can store different color dye solutions. The inclined direction of the dye solution tray 41 faces the transposition main machine 31, that is, the end of the dye solution tray 41 close to the transposition main machine 31 is located below the end of the dye solution tray 41 far from the transposition main machine 31. The dye solution tray 41 arranged to incline towards the transposition main machine 31 can make the dye solution accumulate at one end of the dye solution tray 41 close to the chassis 1 to ensure that there is enough dye solution for printing in the dye solution tray 41.
[0038] Referring to Figure 3 , a support plate 42 is vertically welded on the top wall of the base 4 and on one side of the dye solution tray 41. In this embodiment, the support plate 42 can be a rectangular steel plate. The end of the support plate 42 far from the base 4 is located above the dye solution tray 41, and a printing device is arranged on the side wall of the support plate 42 and above the dye solution tray 41. The printing device can automatically dip the dye solution in the dye solution tray 41, and the printing device can also automatically and accurately print on the cap body.
[0039] Referring to Figure 3 , the printing device includes an adjustment mechanism 5, a printing mechanism 6 and a liquid guiding mechanism 7.

The printing mechanism 6 and the liquid guiding mechanism 7 are both arranged on the side wall of the first moving end 52 facing the dye solution tray 41, and there is a gap between the printing mechanism 6 and the liquid guiding mechanism 7. The printing mechanism 6 is close to the cap mold 2, and the liquid guiding mechanism 7 is located between the printing mechanism 6 and the support plate 42. When the first moving end 52 moves along the length direction of the position adjusting main body 51, the printing mechanism 6 and the liquid guiding mechanism 7 can move synchronously with the first moving end 52.
[0042] Referring to Figure 3 , for the convenience of understanding and description, in this embodiment, the positions of the printing mechanism 6 and the liquid guiding mechanism 7 relative to the printing tray and the cap mold 2 are used as a reference. When the first moving end 52 stays at the middle of the position adjusting main body 51, the liquid guiding mechanism 7 is located above one end of the dye solution tray 41 close to the support plate 42, and the printing mechanism 6 is located above one end of the dye solution tray 41 close to the cap mold 2. At this time, it is defined that the first moving end 52 stays at the first landing point.
[0043] Referring to Figure 1 , when the first moving end 52 stays at the end of the position adjusting main body 51 far from the support plate 42, the liquid guiding mechanism 7 is located above the end of the dye solution tray 41 far from the support plate 42, and the printing mechanism 6 is located above the cap mold 2. At this time, it is defined that the first moving end 52 stays at the second landing point.
[0044] Referring to Figure 3 , when the first moving end 52 stays at the first landing point, the liquid guiding mechanism 7 is in a standby state, and the printing mechanism 6 can dip the dye solution from the dye solution tray 41.
[0045] Referring to Figure 4 , the printing mechanism 6 includes multiple sets of telescopic members 61, a connecting plate 62, multiple sets of mounting members 63 and multiple sets of printing soft molds 64. In this embodiment, the telescopic members 61 can be electric cylinders, and the output ends of the telescopic members 61 have a first stroke length and a second stroke length. Among them, the length dimension of the second stroke length is greater than the length dimension of the first stroke length.
[0046] Referring to Figure 3 and Figure 4The number of telescopic members 61 can be six groups, and the six groups of telescopic members 61 are fixed on a rectangular steel plate by a bolt array, and the rectangular steel plate is further fixed on the side wall of the moving end 52 facing the dye liquid material tray 41 by bolts. The connecting plate 62 can be a rectangular solid steel plate, and the connecting plate 62 is welded on the output end of the six groups of telescopic members 61. In addition, the connecting plate 62 is parallel to the dye liquid material tray 41.
[0047] Reference Figure 4 The mounting member 63 can be an I-shaped solid steel block, and the number of the mounting members 63 can be six groups. The top plate of each group of mounting members 63 is fixed to the side wall of the connecting plate 62 facing the dye liquid material tray 41 by bolts, and all the mounting members 63 are spaced and equidistantly distributed along the length direction of the connecting plate 62.
[0048] Reference Figure 4 , a clearance channel 631 is provided on the bottom plate 11 of each set of mounting parts 63 in the horizontal direction, the clearance channel 631 is dovetail-shaped, and a mounting strip 632 is inserted into the side wall of the clearance channel 631. In this embodiment, the printing soft mold 64 can be a soft printing mold body with a protruding mold on the outer wall, a hollow interior, and the whole can be compressed and deformed after being pressed. The printing soft mold 64 is fixed on the side wall of the mounting strip 632 facing the dye liquid material tray 41 by glue.
[0049] Reference Figure 3 For ease of understanding and explanation, in this embodiment, the number of the printing soft molds 64 can be two groups, and the two groups of printing soft molds 64 are detachably mounted on the two groups of mounting members 63 through the mounting strips 632. A gap is left between the two groups of printing soft molds 64, and the mold prints on the two groups of printing soft molds 64 are different.
[0050] Reference Figure 3 When the moving end 52 stays at the first landing point, the telescopic member 61 extends the output end to the first stroke length, so that the connecting plate 62 carries the printing soft mold 64 to move toward the dye liquid material tray 41 until the printing soft mold 64 enters the inner cavity of the dye liquid material tray 41 and dips into the dye.
[0051] Reference Figure 1 Then, the telescopic member 61 contracts the output end. After that, the mobile end 52 moves and stays at the second landing point. At this time, the liquid guide mechanism 7 moves to the upper part of the dye liquid material tray 41 away from the support plate 42, and the two printing soft molds 64 move to the upper part of the transposition host 31; and one of the printing soft molds 64 is located above the cap mold 2, and the other printing soft mold 64 is located on the side of the cap mold 2.
[0052] Reference Figure 1, the telescopic member 61 extends its output end to the second stroke length, and one of the printing flexible dies 64 can abut against the cap body and print the first type of imprint on the cap body. Then, the telescopic member 61 retracts its output end; the second moving end 32 moves along the length direction of the transposition main machine 31 to make the cap die 2 stay below another printing flexible die 64; the telescopic member 61 extends its output end to the second stroke length again, and the other printing flexible die 64 can print the second type of imprint on the cap body, and the second type of imprint can overlap on the first type of imprint to form a special pattern and / or text combination on the cap body. It should be noted that one of the two types of imprints can be a pattern and the other can be text, subject to the content to be actually printed. The operator can replace the mounting strip 632 to replace different printing flexible dies 64. Finally, after the printing is completed, the telescopic member 61 retracts its output end.
[0053] Refer to Figure 3 , when the first moving end 52 moves to the second dropping position and during the process of the first moving end 52 moving back from the second dropping position to the first dropping position, the liquid guiding mechanism 7 starts to operate. The liquid guiding mechanism 7 includes multiple groups of pushing members 71 and a guide plate 72. In this embodiment, the pushing member 71 can be an electric cylinder, and the number of the pushing members 71 can be two groups. The two groups of pushing members 71 are fixed on a steel plate by bolts, and the steel plate is then fixed on the side wall of the first moving end 52 facing the dyeing liquid tray 41 by bolts.
[0054] Refer to Figure 3 , the guide plate 72 can be a rectangular steel plate, the guide plate 72 is welded on the output ends of the two groups of pushing members 71, and the guide plate 72 is parallel to the dyeing liquid tray 41. Multiple groups of bottom boxes 721 are also welded in an array on the side wall of the guide plate 72 facing the dyeing liquid tray 41. In this embodiment, the number of the bottom boxes 721 is the same as the number of independent spaces in the dyeing liquid tray 41 and can correspond one by one. A liquid guiding soft roller 722 is rotatably arranged in the side wall of each group of bottom boxes 721 through a rotating shaft, and the liquid guiding soft roller 722 can be a soft and easily deformable rubber roller.
[0055] Refer to Figure 3, when the mobile unit 52 is located at the first landing point, or even when the mobile unit 52 has just moved to the second landing point, the liquid guide soft roller 722 is always located above the dye solution tray 41. Before the outer extension output end of the telescopic member 61, the outer extension output end of the pushing member 71 causes the liquid guide soft roller 722 to enter the dye solution tray 41 and be immersed in the dye solution. After the printing soft mold 64 has completed printing on the cap body, during the process of the mobile unit 52 returning from the second landing point to the first landing point, the liquid guide soft roller 722 can move along with the mobile unit 52. The moving liquid guide soft roller 722 reduces the contact with the inner wall of the dye solution tray 41 through compression deformation, and can evenly push the dye solution from the bottom of the dye solution tray 41 to the middle of the dye solution tray 41 during the moving process. Then, after the mobile unit 52 returns to the first landing point, the pushing member 71 contracts its output end and moves the liquid guide soft roller 722 above the dye solution tray 41, and the dye solution that has moved to the middle of the dye solution tray 41 can flow back to the bottom of the dye solution tray 41 under the action of gravity. During this process, the dye solution moves and converges, enabling the coloring substances in the dye solution to be evenly distributed in each layer of the dye solution, which helps to reduce the problem that the coloring substances in the dye solution settle at the bottom of the dye solution tray 41 due to the long-term accumulation of the dye solution at the bottom of the dye solution tray 41, and further causes unclear printing when the printing soft mold 64 dips the dye solution and prints on the cap body.
[0056] The implementation principle of an automatic printing device for safety helmets in an embodiment of the present application is as follows: After the cap body is fitted over the cap mold 2, the outer extension output end of the reversing air cylinder 321 pushes the side plate 13, causing the support plate 12 to rotate towards the baffle 322, so that the cap mold 2 and the cap body approach the baffle 322 and face the baffle 322. Then, the outer extension output end of the cap pushing air cylinder 121 causes the cap mold 2 and the cap body to move towards the baffle 322 until the cap body abuts tightly against the baffle 322, and thus the cap body is clamped tightly between the cap mold 2 and the baffle 322.
[0057] At this time, the position of the cap body is fixed, and the mobile unit 52 stays at the first landing point. The outer extension output end of the telescopic member 61 extends to the first stroke length, causing the connecting plate 62 to carry the printing soft mold 64 to move towards the dye solution tray 41 until the printing soft mold 64 enters the inner cavity of the dye solution tray 41 and dips the dye solution. Then, the telescopic member 61 contracts its output end.
[0058] The mobile unit 52 moves and stops at the second landing point. The outer extending output end of the pushing member 71 causes the liquid guiding soft roller 722 to enter the dye solution tray 41 and be immersed in the dye solution. The outer extending output end of the telescopic member 61 reaches the second stroke length, and the printing soft mold 64 can abut against the cap body and print a kind of mark on the cap body; if multiple marks need to be printed on the cap body, the mobile unit 32 can move along the length direction of the transposition main machine 31 to position the cap mold 2 under different printing soft molds 64. Then, by extending the output end of the telescopic member 61 to the second stroke length again, another mark can be printed on the cap body by the printing soft mold 64.
[0059] After printing, the telescopic member 61 contracts its output end, and the mobile unit 52 returns from the second landing point to the first landing point. At this time, the output end of the pushing member 71 always remains in the extended state, and the liquid guiding soft roller 722 can move along with the mobile unit 52. The moving liquid guiding soft roller 722 reduces the contact with the inner wall of the dye solution tray 41 through compressive deformation, and during the movement of the liquid guiding soft roller 722, the dye solution can be evenly pushed from the bottom of the dye solution tray 41 to the middle of the dye solution tray 41, thereby ensuring the printing clarity of the dye solution during subsequent printing through the movement of the dye solution in the dye solution tray 41.
[0060] Embodiment 2 The difference between Embodiment 2 and Embodiment 1 of this application is that with reference to Figure 5 , the printing mechanism 6 further includes a guide rod 73. The guide rod 73 is an L-shaped steel rod, and one end in the length direction of the guide rod 73 is welded to the side wall of the mounting member 63.
[0061] With reference to Figure 6 , a sleeve 731 is slidably sleeved on the end of the guide rod 73 away from the mounting member 63. The sleeve 731 can be a linear steel cylinder with an inner diameter dimension adapted to the outer diameter dimension of the guide rod 73. The sleeve 731 can move and be positioned freely on the guide rod 73, and moreover, the sleeve 731 cannot completely break away from the guide rod 73.
[0062] With reference to Figure 6 , a hose 732 is fixed to the end of the sleeve 731 away from the guide rod 73 by bolts. In this embodiment, the hose 732 can be a rubber tube that can be bent and deformed, and moreover, the hose 732 can maintain its shape after being bent and deformed. The end of the hose 732 away from the sleeve 731 is fixed with a hot air blower 733 by bolts, and the hot air blower 733 can blow hot air above 100 °C.
[0063] With reference to Figure 6, before the printing soft mold 64 prints on the cap body at the extended output end of the telescopic member 61, the operator can slide the extension cylinder 731 to move the hot air blower 733 away from the guide rod 73. Then, the operator can bend the hose 732 to bring the hot air blower 733 closer to the cap body, so that the hot air blower 733 can blow hot air against the printing area of the cap body. After the printing area of the cap body is heated and the temperature rises, it helps to make the imprint printed by the printing soft mold 64 on the cap body clearer and the molding more stable.
[0064] The implementation principle of an automatic printing device for safety helmets in an embodiment of the present application is as follows: The extension cylinder 731 can adjust the distance between the hot air blower 733 and the cap body by sliding on the guide rod 73. After the hose 732 is bent and deformed, the blowing port of the hot air blower 733 can be close to and face the printing area of the cap body. After the hot air blower 733 blows hot air against the printing area of the cap body, the printing area of the cap body can be heated and the temperature rises, which in turn helps to make the imprint printed by the printing soft mold 64 on the cap body clearer and the molding more stable, improving the printing quality of the printing device on the cap body.
[0065] The above are all preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
