Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and more particularly to an automated printing equipment for safety helmets. Background Technology

[0002] Plastic safety helmets require special text or patterns to be printed on them after molding. For example, on construction sites, standardized safety helmets need to have the construction company's name and logo printed on the brim to facilitate quick identification and unified management of construction workers on site.

[0003] In the actual processing of safety helmets with printing requirements, operators mostly hold the printing module to dip it into the dye box. Then, the dye-soaked printing module is pressed onto the safety helmet. At this time, the safety helmet is mostly still held by the operator, so that the text and / or graphics on the printing module can be formed on the safety helmet.

[0004] However, manually printing on safety helmets by operators presents problems of low efficiency; furthermore, since the safety helmets are not positioned during manual printing, operators mostly rely on feeling or experience to print on them, which can easily lead to inconsistencies in the position of the printed markings on different safety helmets; in addition, there may be inconsistencies in the depth and clarity of the printed content on different batches of safety helmets, making it difficult to guarantee the printing quality; therefore, improvements are needed. Summary of the Invention

[0005] Purpose of the invention: This application provides an automated printing equipment for safety helmets, which aims to improve the technical problems of low efficiency in printing on safety helmets by manpower, inconsistent positioning of printed markings, and difficulty in ensuring printing quality control.

[0006] Technical Solution: This application provides an automated printing equipment for safety helmets, comprising: a helmet-fixing device for placing the helmet body and fixing its position; a base, on which a dye tray for storing dye is disposed in a direction inclined toward the helmet-fixing device; a support plate is disposed on one side of the dye tray on the base, and a printing device is disposed on the support plate; the printing device includes an adjusting mechanism parallel to the dye tray, and a printing mechanism disposed on the adjusting mechanism and movable by the adjusting mechanism; when the adjusting mechanism controls the printing mechanism to stop at a first landing point, the printing mechanism can be dipped in dye in the dye tray; when the adjusting mechanism controls the printing mechanism to land at a second landing point, the printing mechanism can print on the helmet body fixed on the helmet-fixing device.

[0007] By adopting the above technical solution, the cap body can be quickly and stably positioned by 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 already positioned cap body at the second landing point, which helps to ensure the uniformity of the printing position and the clarity of the printing on the cap body. The positioning mechanism controls the reciprocating movement of the printing mechanism between the first landing point and the second landing point to realize the separate operation of dye dipping and cap body printing. This can ensure the continuity and stability of the cap body printing, and also ensure that the printing mechanism always has enough dye to print clearly on the cap body.

[0008] Further, the cap-fixing device includes a base frame and a cap mold mounted on the base frame; the cap mold is located below the dye bath, and the cap body can be fitted onto the cap mold for positioning; the adjusting mechanism is a linear motor, and the adjusting mechanism includes an adjusting host mounted on the end of the support plate away from the base and parallel to the dye bath, and a movable end mounted on the adjusting host; the printing mechanism includes multiple sets of telescopic components arrayed on the movable end, a connecting plate mounted on the output ends of all the telescopic components, multiple sets of mounting components arrayed on the connecting plate, and a deformable printing soft mold mounted on the mounting components; wherein, the telescopic component is an electric cylinder; when the movable end stops at the first landing point, the output end of the telescopic component can extend outward by a first stroke length, so that the printing soft mold moves into the dye bath to be dipped in dye; when the movable end stops at the second landing point, the output end of the telescopic component can extend outward by a second stroke length, so that the printing soft mold can print on the cap body positioned on the cap mold.

[0009] By adopting the above technical solution, when the mobile end moves to the first landing point, the telescopic component can extend its output end to the first stroke length, allowing the printing mold to dip into the dye bath; when the mobile end moves to the second landing point, the telescopic component can extend its output end to the second stroke length, allowing the printing mold to print on the already positioned cap mold; this process realizes the separation of dye dipping and printing operations and the standardization of the process, and can effectively ensure the positional accuracy and clarity of the printing mold on the cap body when the cap body is already positioned.

[0010] Furthermore, the mounting component is an I-shaped steel block, and a dovetail-shaped clearance channel is provided through the mounting component; an installation strip is adapted to be inserted into the side wall of the clearance channel, and the printing soft mold is disposed on the bottom wall of the installation strip.

[0011] By adopting the above technical solution, the mounting strip is quickly and stably positioned on the mounting component by inserting into the clearance channel, while the printing soft mold is fixed on the bottom wall of the mounting strip, thereby realizing the rapid installation and positioning of the printing soft mold on the mounting component; in addition, the mounting strip can also be quickly disassembled from the mounting component by sliding and pulling it out of the clearance channel.

[0012] Furthermore, the printing mechanism also includes a guide rod disposed on the mounting component; the guide rod is L-shaped, one end of the guide rod is slidably connected to an extension cylinder, the end of the extension cylinder away from the guide rod is provided with a flexible hose that can be bent and deformed, and the end of the flexible hose away from the extension cylinder is provided with a hot air blower that can blow hot air onto the area of ​​the cap to be printed.

[0013] By adopting the above technical solution, the distance between the hot air blower and the cap body can be adjusted by sliding the extension tube on the guide rod. After the hose is bent and deformed, the blowing nozzle of the hot air blower can be brought closer to and towards the area to be printed on the cap body. After the hot air blower blows hot air onto the area to be printed on the cap body, the area to be printed on the cap body will be heated and heated, which will help to make the printing mold print clearer and more stable on the cap body, thus improving the printing quality of the printing device on the cap body.

[0014] Furthermore, the printing apparatus also includes a liquid guiding mechanism, which includes multiple sets of pushing members disposed on the movable end and located on one side of all the telescopic members, and a guide plate disposed on the output end of all the pushing members; the pushing members are electric cylinders; multiple sets of base boxes are arrayed on the side wall of the guide plate facing the dye bath, and each set of base boxes is rotatably provided with a flexible and deformable liquid guiding roller; during the process of the movable end moving from the first drop point to the second drop point, the liquid guiding roller is always located above the dye bath; after the movable end is positioned at the second drop point, the pushing member extends its output end to make the liquid guiding roller abut against the dye bath to be dyed; during the process of the movable end moving from the second drop point to the first drop point, the liquid guiding roller moves by compression deformation to drive the dye to move within the dye bath; after the movable end returns to the first drop point, the pushing member retracts its output end to move the liquid guiding roller above the dye bath.

[0015] By adopting the above technical solution, when the mobile end is at the first landing point and when the mobile end has just moved to the second landing point, the liquid guiding roller is always positioned above the dye bath. Before the extension output end of the telescopic component, the extension output end of the push component causes the liquid guiding roller to enter the dye bath and be immersed in the dye. After the printing mold completes printing on the cap body, during the process of the mobile end returning from the second landing point to the first landing point, the liquid guiding roller can move with the mobile end. The moving liquid guiding roller reduces the contact with the inner wall of the dye bath through compression deformation, and can evenly distribute the dye from the bottom of the dye bath while maintaining movement. The dye is evenly pushed to the middle of the dye bath tray; then, after the moving end returns to the first landing point, the pushing component retracts the output end and moves the liquid guiding roller above the dye bath tray. The dye that has moved to the middle of the dye bath tray can flow back to the bottom of the dye bath tray under the action of gravity. In this process, the dye achieves movement and convergence, which can make the coloring substances in the dye evenly distributed in each layer of the dye bath. This helps to reduce the problem of the coloring substances in the dye settling at the bottom of the dye bath tray due to the long-term accumulation of dye, which would lead to unclear printing on the cap after the printing mold dips in the dye.

[0016] Furthermore, the cap fixing device also includes a shifting mechanism for moving the cap mold. The shifting mechanism is a linear motor and includes a shifting host parallel to the connecting plate and a second movable end movably disposed on the shifting host. The base frame is fixed on the second movable end. When adjacent printing soft molds are printing soft molds with different printing molds, the second movable end can move along the length direction of the shifting host between the two extension strokes of the telescopic member, so that the printing soft molds with different printing molds can be printed on the cap body respectively.

[0017] By adopting the above technical solution, the second mobile terminal moves along the length of the switching host, so that the cap mold can stay under different printing soft molds, thereby facilitating the printing soft molds with different imprints to print on the cap mold, so as to form a combination of text and / or patterns that meet the production needs on the cap mold.

[0018] Furthermore, the base frame includes a base plate fixed to the second movable end, a support plate rotatably mounted on the base plate, and a side plate fixedly mounted on the side wall of the support plate; a reversing cylinder is rotatably mounted on the top wall of the second movable end and located on one side of the base plate, and the output end of the reversing cylinder is rotatably connected to the side plate; a cap-pushing cylinder is also fixedly mounted on the side wall of the support plate and above the side plate, and the output end of the cap-pushing cylinder passes through the support plate and is fixedly connected to the cap mold; a baffle is also fixedly mounted on the top wall of the second movable end and on the side of the base plate away from the cap-pushing cylinder; after the reversing cylinder extends its output end, it can cause the support plate to rotate toward the baffle; after the cap-pushing cylinder extends its output end, it can cause the cap mold to move toward the baffle and cause the cap body to 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 placed on the cap mold. Then, the output end of the reversing cylinder extends to push the side plate, causing the support plate to rotate towards the baffle, thereby bringing the cap mold and cap body closer to the baffle and facing the baffle. Next, the output end of the pushing cylinder extends to move the cap mold and cap body towards the baffle until the cap body is pressed against the baffle. At this time, the abutting block is compressed and pressed against the cap body and the baffle, and the cap body can be pressed between the cap mold and the baffle. The position of the cap body is stabilized and fixed, effectively reducing the problem of printing misalignment caused by cap body movement and swaying during the printing process.

[0020] Furthermore, a flexible and deformable abutment block is provided on the side wall of the baffle facing the hat mold, and the abutment block can be pressed tightly between the baffle and the hat body.

[0021] By adopting the above technical solution, the abutment block can be subjected to force and compressive deformation as the cap body and the baffle approach each other. After being compressed, the abutment block compresses and deforms to press firmly between the cap body and the baffle, which helps to ensure the positional stability of the cap body on the cap mold.

[0022] In summary, this application has at least the following beneficial technical effects: The cap body can be quickly and stably positioned by the cap fixing device, which can fix the cap body in a specific position and effectively reduce the problem of the cap body moving or swaying 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 uniformity of the printing position and the clarity of the printing on the cap body. The adjustment mechanism controls the reciprocating movement of the printing mechanism between the first landing point and the second landing point to realize the separate operation of dye dipping and cap body printing. This can ensure the continuity and stability of the cap body printing, and also ensure that the printing mechanism always has enough dye to print clearly on the cap body. When the movable end is at the first landing point and when it has just moved to the second landing point, the liquid guiding roller is always positioned above the dye bath. Before the telescopic component extends outward, the pushing component extends outward to allow the liquid guiding roller to enter the dye bath and be immersed in the dye. After the printing mold completes printing on the cap, as the movable end returns from the second landing point to the first landing point, the liquid guiding roller moves with the movable end. The moving liquid guiding roller reduces the contact with the inner wall of the dye bath through compression deformation, and while maintaining movement, it can evenly push the dye from the bottom of the dye bath to the dye bath. The middle of the liquid tray; then, after the moving end returns to the first landing point, the pushing component retracts the output end and moves the liquid guiding roller above the dye tray. The dye liquid that has moved to the middle of the dye tray can flow back to the bottom of the dye tray under the action of gravity. In this process, the dye liquid moves and converges, which can make the coloring substances in the dye liquid evenly distributed in each layer of the dye liquid. This helps to reduce the problem of unclear printing when the printing mold dips into the dye liquid and prints on the cap after the dye liquid has been accumulated at the bottom of the dye tray for a long time.

[0025] This application discloses an automated printing equipment for safety helmets.

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] Example 1 Reference Figure 1 An automated printing device for safety helmets is used to position the helmet body and to automatically print on the positioned helmet body.

[0028] Reference Figure 1 Specifically, the automated safety helmet printing equipment includes a helmet fixing device, which in turn includes a base frame 1, a helmet mold 2, and a shifting mechanism 3. The helmet mold 2 is mounted on the shifting mechanism 3 via 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 moving end 32. 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 placed directly 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 mounted on the transposition host 31. The second mobile terminal 32 can move back and forth along the length of the transposition host 31, and the second mobile terminal 32 can stop at any position on its movement path.

[0031] Reference Figure 2The base frame 1 is mounted on the top wall of the movable end 32, and the base frame 1 includes a base plate 11. In this embodiment, the base plate 11 can be a rectangular solid steel plate, and the base plate 11 is welded to the top wall of the movable end 32. A support plate 12 is rotatably mounted on the top wall of the base plate 11 via a pivot, and the support plate 12 is also a rectangular solid steel plate. A side plate 13 is also vertically welded to one side wall of the support plate 12 in the width direction.

[0032] Reference Figure 2 A reversing cylinder 321 is rotatably mounted on the top wall of the movable end 32, located on one side of the base plate 11, via 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 by a rotating shaft. In this embodiment, when the output end of the reversing cylinder 321 is in a retracted state, the angle between the support plate 12 and the base plate 11 is approximately 60°. When the output end of the reversing cylinder 321 extends outward, it can push the side plate 13 and the support plate 12 to move in the direction of extension, thereby enabling the support plate 12 to rotate on the base plate 11 and increasing the angle between the support plate 12 and the base plate 11 to approximately 80°.

[0033] Reference Figure 2 A cap-pushing cylinder 121 is bolted to the side wall of the support plate 12, located on the side where the side plate 13 is provided. The cap-pushing cylinder 121 is located above the side plate 13, and its output end passes through the support plate 12. The cap mold 2 is welded to the end wall along the length of the output end of the cap-pushing cylinder 121. In this embodiment, the outer circumference of the cap mold 2 is adapted to the cap body. The cap body to be printed can be fitted onto the cap mold 2 in a size-fitting manner. Since the shape of the cap body matches the cap mold 2, the ease of fitting the cap body onto the cap mold 2 and its positional stability can be ensured, thereby helping to reduce problems such as movement and swaying of the cap body during the printing process.

[0034] Reference Figure 2 To improve the positional stability of the cap body on the cap mold 2, a baffle 322 is welded to the top wall of the moving end 32. The baffle 322 is located at the end of the cap mold 2 away from the cap-pushing cylinder 121, and a gap is left between the cap mold 2 and the baffle 322 when the output end of the cap-pushing cylinder 121 is in the retracted state. An abutment block 323 is also glued to the side wall of the baffle 322 facing the cap mold 2. In this embodiment, the abutment block 323 can be a flexible and easily deformable rubber block.

[0035] After the cap body to be printed is placed on the cap mold 2, it can be initially positioned. Then, the output end of the reversing cylinder 321 extends to push the side plate 13, causing the support plate 12 to rotate towards the baffle 322, thereby bringing the cap mold 2 and the cap body closer to the baffle 322 and facing it. Next, the output end of the pushing cylinder 121 extends, causing the cap mold 2 and the cap body to move towards the baffle 322 until the cap body is pressed against the baffle 322. At this time, the abutting block 323 is compressed and pressed against the cap body and the baffle 322, and the cap body can be pressed between the cap mold 2 and the baffle 322. The position of the cap body is stabilized and fixed, effectively reducing the problem of printing misalignment caused by the movement and swaying of the cap body during the printing process. In addition, the moving end 32 can reciprocate along the length of the switching host 31 and stop at any position on its movement path, so that the cap body can receive printing of different molds at different positions.

[0036] Reference Figure 1 In order to enable automated and precise printing on the helmet body, the automated helmet printing equipment also includes a base 4. In this embodiment, the base 4 can be a rectangular operating table, which is placed on the ground and located on one side of the width direction of the transposition host 31. Furthermore, the top wall of the base 4 is located above the top wall of the helmet mold 2.

[0037] Reference Figure 1 A dyeing solution tray 41 is inclinedly arranged on the top wall of the base 4. In this embodiment, the dyeing solution tray 41 is a dyeing solution box with multiple independent spaces, and different colors of dyeing solution can be stored in different independent spaces. The inclined direction of the dyeing solution tray 41 is towards the switching host 31, that is, the end of the dyeing solution tray 41 near the switching host 31 is located below the end of the dyeing solution tray 41 away from the switching host 31. The dyeing solution tray 41 inclined towards the switching host 31 can make the dyeing solution accumulate at the end of the dyeing solution tray 41 near the base frame 1, so as to ensure that there is enough dyeing solution in the dyeing solution tray 41 for printing.

[0038] Reference Figure 3 A support plate 42 is vertically welded to the top wall of the base 4 and to one side of the dye bath 41. In this embodiment, the support plate 42 can be a rectangular steel plate. The end of the support plate 42 away from the base 4 is located above the dye bath 41. A printing device is provided on the side wall of the support plate 42 and above the dye bath 41. The printing device can automatically pick up dye from the dye bath 41 and can also automatically and accurately print on the cap.

[0039] Reference Figure 3 The printing apparatus includes a positioning mechanism 5, a printing mechanism 6, and a liquid guiding mechanism 7.

[0040] Reference Figure 3In this embodiment, the adjustment mechanism 5 can be a linear motor. The adjustment mechanism 5 includes an adjustment host 51 and a moving end 52. One end of the adjustment host 51 in the longitudinal direction is fixed to the side wall of the support plate 42 by bolts. The adjustment host 51 is located above the dye liquor tray 41 and extends along the longitudinal direction of the dye liquor tray 41. The adjustment host 51 is also parallel to the dye liquor tray 41.

[0041] Reference Figure 3 The movable end 52 is movably mounted on the adjusting host 51. The movable end 52 can reciprocate along the length of the adjusting host 51 and stop at any position along its movement path. The printing mechanism 6 and the liquid guiding mechanism 7 are both mounted on the side wall of the movable end 52 facing the dye bath 41, with a gap between them. The printing mechanism 6 is close to the cap mold 2, while the liquid guiding mechanism 7 is located between the printing mechanism 6 and the support plate 42. When the movable end 52 moves along the length of the adjusting host 51, the printing mechanism 6 and the liquid guiding mechanism 7 can move synchronously with the movable end 52.

[0042] Reference Figure 3 For ease of understanding and explanation, 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 references. When the moving end 52 stops at the middle of the adjusting host 51, the liquid guiding mechanism 7 is located above the end of the dye tray 41 near the support plate 42, and the printing mechanism 6 is located above the end of the dye tray 41 near the cap mold 2. This is defined as the moving end 52 stopping at the first landing point.

[0043] Reference Figure 1 When the mobile end 52 stops at the end of the adjusting host 51 away from the support plate 42, the liquid guiding mechanism 7 is located above the end of the dye liquid tray 41 away from the support plate 42, and the printing mechanism 6 is located above the cap mold 2. This is defined as the mobile end 52 stopping at the second landing point.

[0044] Reference Figure 3 When the mobile terminal 52 stops at the first landing point, the liquid guiding mechanism 7 is in standby mode, and the printing mechanism 6 can dip into the dye liquid tray 41.

[0045] Reference Figure 4 The printing mechanism 6 includes multiple sets of telescopic components 61, a connecting plate 62, multiple sets of mounting components 63, and multiple sets of printing soft molds 64. In this embodiment, the telescopic component 61 can be an electric cylinder. The output end of the telescopic component 61 has a first stroke length and a second stroke length, wherein the length dimension of the second stroke length is greater than the length dimension of the first stroke length.

[0046] Reference Figure 3 and Figure 4The telescopic components 61 can be in six sets, and the six sets of telescopic components 61 are fixed to a rectangular steel plate by an array of bolts. The rectangular steel plate is then fixed to the side wall of the moving end 52 facing the dye liquor tray 41 by bolts. The connecting plate 62 can be a rectangular solid steel plate, and the connecting plate 62 is welded to the output end of the six sets of telescopic components 61. Furthermore, the connecting plate 62 is parallel to the dye liquor tray 41.

[0047] Reference Figure 4 The mounting component 63 can be an I-shaped solid steel block, and the number of mounting components 63 can be six sets. The top plate of each set of mounting components 63 is fixed to the side wall of the connecting plate 62 facing the dye liquor tray 41 by bolts, and all mounting components 63 are spaced apart and equidistantly distributed along the length of the connecting plate 62.

[0048] Reference Figure 4 Each set of mounting components 63 has a horizontally extending clearance channel 631 on its base plate 11. The clearance channel 631 is dovetail-shaped, and a mounting strip 632 is fitted 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 protruding molded marks on the outer side wall, hollow inside, and capable of compressing and deforming under pressure. The printing soft mold 64 is fixed to the side wall of the mounting strip 632 facing the dye bath 41 by adhesive.

[0049] Reference Figure 3 For ease of understanding and explanation, in this embodiment, the number of printing molds 64 can be two sets, and the two sets of printing molds 64 are detachably mounted on two sets of mounting members 63 via mounting strips 632. A gap is left between the two sets of printing molds 64, and the imprints on the two sets of printing molds 64 are different.

[0050] Reference Figure 3 When the moving end 52 stops 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 toward the dye liquor tray 41 until the printing soft mold 64 enters the inner cavity of the dye liquor tray 41 and picks up the dye liquor.

[0051] Reference Figure 1 Next, the telescopic component 61 retracts its output end. Then, the moving end 52 moves and stops at the second landing point. At this time, the liquid guiding mechanism 7 moves to the top of the dye liquor tray 41 away from the support plate 42, and the two printing soft molds 64 move to the top of the switching host 31; and one of the printing soft molds 64 is located above the cap mold 2, while the other printing soft mold 64 is located on one side of the cap mold 2.

[0052] Reference Figure 1The telescopic component 61 extends its output end to the second stroke length, allowing one of the printing molds 64 to abut against the cap body and print a first mark on it. Next, the telescopic component 61 retracts its output end; the moving end 32 moves along the length of the switching host 31, causing the cap mold 2 to stop below the other printing mold 64; the telescopic component 61 then extends its output end again to the second stroke length, allowing the other printing mold 64 to print a second mark on the cap body. This second mark can overlap the first mark to form a special pattern and / or text combination on the cap body. It should be noted that the two marks can be either a pattern or text, depending on the actual content to be printed. The operator can replace different printing molds 64 by replacing the mounting strip 632. Finally, after printing is complete, the telescopic component 61 retracts its output end.

[0053] Reference Figure 3 When the movable end 52 moves to the second landing point, and during the process of the movable end 52 moving back from the second landing point to the first landing point, the liquid guiding mechanism 7 starts to operate. The liquid guiding mechanism 7 includes multiple sets of pushing members 71 and a guide plate 72. In this embodiment, the pushing members 71 can be electric cylinders, and the number of pushing members 71 can be two sets. The two sets of pushing members 71 are fixed to a steel plate by bolts, and the steel plate is then fixed to the side wall of the movable end 52 facing the dye liquor tray 41 by bolts.

[0054] Reference Figure 3 The guide plate 72 can be a rectangular steel plate, welded to the output ends of the two sets of pushers 71, and parallel to the dye liquor tray 41. Multiple sets of base boxes 721 are also arrayed and welded to the sidewall of the guide plate 72 facing the dye liquor tray 41. In this embodiment, the number of base boxes 721 is the same as the number of independent spaces in the dye liquor tray 41, and they correspond one-to-one. Each set of base boxes 721 has a liquid-guiding soft roller 722 rotatably mounted on its sidewall via a rotating shaft. The liquid-guiding soft roller 722 can be a soft and easily deformable rubber roller.

[0055] Reference Figure 3When the moving end 52 is at the first landing point, and even when the moving end 52 has just moved to the second landing point, the liquid guiding roller 722 is always positioned above the dye bath 41. Before the extension end of the telescopic member 61 extends outward, the extension end of the pushing member 71 causes the liquid guiding roller 722 to enter the dye bath 41 and be immersed in the dye. After the printing mold 64 completes printing on the cap body, as the moving end 52 returns from the second landing point to the first landing point, the liquid guiding roller 722 can move along with the moving end 52. The moving liquid guiding roller 722 reduces the contact with the inner wall of the dye bath 41 through compression deformation, and can evenly push the dye from the bottom of the dye bath 41 to the middle of the dye bath 41 while maintaining movement. Next, after the moving end 52 returns to the first landing point, the pushing component 71 retracts the output end and moves the liquid guiding roller 722 above the dye bath 41. The dye bath that has moved to the middle of the dye bath 41 can flow back to the bottom of the dye bath 41 under the action of gravity. In this process, the dye bath moves and converges, which can make the coloring substances in the dye bath evenly distributed in each layer of the dye bath. This helps to reduce the problem of the coloring substances in the dye bath settling at the bottom of the dye bath due to the dye bath accumulating for a long time, which would cause the printing mold 64 to be dipped in the dye bath and print unclearly on the cap body.

[0056] The implementation principle of the automated printing equipment for safety helmets according to an embodiment of this application is as follows: After the helmet body is fitted onto the helmet mold 2, the output end of the reversing cylinder 321 extends to push the side plate 13, causing the support plate 12 to rotate towards the baffle 322, thereby enabling the helmet mold 2 and the helmet body to approach the baffle 322 and be oriented towards the baffle 322. Next, the output end of the pushing cylinder 121 extends to move the helmet mold 2 and the helmet body towards the baffle 322 until the helmet body is pressed against the baffle 322, thereby pressing the helmet body between the helmet mold 2 and the baffle 322.

[0057] At this point, the position of the cap is fixed, and the moving end 52 stops at the first landing point. The telescopic component 61 extends its output end to the first stroke length, causing the connecting plate 62 to carry the printing mold 64 toward the dye bath 41 until the printing mold 64 enters the inner cavity of the dye bath 41 and picks up the dye. Then, the telescopic component 61 retracts its output end.

[0058] The first movable end 52 moves and stops at the second landing point, and the pushing member 71 extends its output end to allow the liquid guiding roller 722 to enter the dye bath 41 and be immersed in the dye solution. The telescopic member 61 extends its output end to the second stroke length, allowing the printing mold 64 to abut against the cap body and print a mark on the cap body; if multiple marks need to be printed on the cap body, the second movable end 32 can move along the length direction of the switching host 31, so that the cap mold 2 is positioned under different printing molds 64. Then, by extending its output end to the second stroke length again through the telescopic member 61, the printing mold 64 prints another mark on the cap body.

[0059] After printing, the telescopic component 61 retracts its output end, and the moving end 52 returns from the second landing point to the first landing point. At this time, the output end of the pushing component 71 remains in the extended state, and the liquid guiding roller 722 can move with the moving end 52. The moving liquid guiding roller 722 reduces the contact with the inner wall of the dye liquor tray 41 through compression deformation. Furthermore, during the movement of the liquid guiding roller 722, the dye liquor can be evenly pushed from the bottom of the dye liquor tray 41 to the middle of the dye liquor tray 41. Thus, the movement of the dye liquor within the dye liquor tray 41 ensures the clarity of the subsequent printing.

[0060] Example 2 The difference between Embodiment 2 and Embodiment 1 of this application is that, referring to... Figure 5 The printing mechanism 6 also includes a guide rod 73. The guide rod 73 is an L-shaped steel rod, and one end of the guide rod 73 in the longitudinal direction is welded to the side wall of the mounting part 63.

[0061] Reference Figure 6 The end of the guide rod 73 furthest from the mounting part 63 is slidably fitted with an extension cylinder 731. The extension cylinder 731 can be a straight steel cylinder with an inner diameter that matches the outer diameter of the guide rod 73. The extension cylinder 731 can move and be positioned freely on the guide rod 73, and the extension cylinder 731 cannot be completely detached from the guide rod 73.

[0062] Reference Figure 6 The end of the extension cylinder 731 away from the guide rod 73 is fixed with a flexible hose 732 by bolts. In this embodiment, the flexible hose 732 can be a flexible rubber tube that can be bent and deformed, and the flexible hose 732 can maintain its shape after bending and deformation. The end of the flexible hose 732 away from the extension cylinder 731 is fixed with a hot air blower 733 by bolts. The hot air blower 733 can blow out hot air at a temperature of over 100°C.

[0063] Reference Figure 6Before the printing mold 64 is printed on the cap body by extending the telescopic component 61 to the output end, the operator can slide the extension tube 731 to move the hot air blower 733 away from the guide rod 73. Next, the operator can bend the hose 732 to bring the hot air blower 733 closer to the cap body, allowing the hot air blower 733 to blow hot air onto the area of ​​the cap body to be printed. After the area of ​​the cap body to be printed is heated, it helps to make the printing mold 64 print clearer and more stable on the cap body.

[0064] The implementation principle of the automated printing equipment for safety helmets in this application embodiment is as follows: the extension tube 731 can adjust the distance between the hot air blower 733 and the helmet body by sliding on the guide rod 73. After the flexible tube 732 is bent and deformed, the blowing nozzle of the hot air blower 733 can be brought closer to and towards the area to be printed on the helmet body. After the hot air blower 733 blows hot air onto the area to be printed on the helmet body, the area to be printed on the helmet body is heated up, which helps to make the imprint of the printing mold 64 on the helmet body clearer and more stable, thus improving the printing quality of the printing device on the helmet body.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
