DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0034] Referring to Figure 1 and Figure 2 A line tube printer 100 provided by the embodiment of the application, the line tube printer 100 comprises a host 1, a print head seat 2 and a heating print head 3, the print head seat 2 can be arranged on the host 1, and the print head seat 2 comprises a first part 21 and a second part 22 connected with each other, the first part 21 is located below the second part 22, and the first part 21 is also connected with the host 1, the heating print head 3 is arranged on the first part 21, and the heating print head 3 is spaced apart from the free end of the print head seat 2, and the heating print head 3 can be used for printing on a line tube 4.

[0035] Optionally, the line tube printer 100 is a device specially used for printing characters on PVC sleeves, heat-shrinkable tubes and other line tubes 4, the host 1 is the core control part of the line tube printer 100, responsible for receiving and processing print instructions, and controlling the coordinated work of various components, and the host 1 usually contains circuit boards, processors, memories and other electronic elements, and necessary interfaces and buttons for interacting with operators.

[0036] The print head seat 2 is a component for fixing and supporting the heating print head 3, and the print head seat 2 is generally also drivenly connected with an adjusting mechanism, so as to adjust the position and angle of the heating print head 3 according to the printing requirements, so that the heating print head 3 can stably perform the printing work, in the embodiment, the print head seat 2 comprises the first part 21 and the second part 22 connected with each other, the first part 21 is connected with the host 1, and the first part 21 is located below the second part 22, or in other words, the second part 22 is more protruding than the first part 21 from the outer surface of the host 1.

[0037] The heating print head 3 is a key component of the line tube printer 100 for printing, the heating print head 3 melts the ink or ribbon on the printing material (such as the line tube 4 of the PVC sleeve, the heat-shrinkable tube and the like) by heating, so as to realize the printing effect, the heating print head 3 can be extended to the inside of the host 1, and the heating print head 3 is arranged on the first part 21, and the heating print head 3 is also spaced apart from the free end of the print head seat 2, that is, there is a space between the heating print head 3 and the second part 22, so that the heating print head 3 is arranged below the second part 22, when the heating print head 3 prints on the line tube 4, the second part 22 can prevent the user from directly touching the heating print head 3, and the risk of the user being scalded by the heating print head 3 can be reduced.

[0038] Further, in order to continuously and stably print the line tube 4, referring to Figures 1 to 3The wire number tube printer 100 comprises a printing roller 5, which is located at the side of the printing head seat 2 provided with the heating printing head 3, and a wire channel 6 for the wire number tube 4 to pass through is formed between the printing roller 5 and the printing head seat 2. The printing head seat 2 can move away from or close to the printing roller 5.

[0039] Optionally, the printing roller 5 can also be connected to the host computer 1, and the printing roller 5 is arranged away from the printing head seat 2, the heating printing head 3 is located between the printing head seat 2 and the printing roller 5, the printing head seat 2 can move relative to the printing roller 5, and the printing head seat 2 can be switched between the printing position and the tube placing position.

[0040] More clearly, in combination with Figure 3 The printing head seat 2 can move relative to the printing roller 5 to the printing position in the direction close to the printing roller 5, at this time, the printing head seat 2 and the printing roller 5 can clamp the wire number tube 4, and the heating printing head 3 can heat to realize printing on the wire number tube 4. After printing is completed, in combination with Figure 2 The printing head seat 2 can move relative to the printing roller 5 to the tube placing position in the direction away from the printing roller 5, at this time, there is a certain gap between the printing head seat 2 and the printing roller 5, which is greater than the diameter of the wire number tube 4, so as to relax the wire number tube 4, so that the wire number tube 4 can move in the wire passing direction (X direction in the figure is the wire passing direction). Through the above process, continuous printing on the wire number tube 4 can be realized, and printing is also more stable. Figure 4

[0041] Further, please refer to Figure 2 When the printing head seat 2 moves to the maximum spacing position in the direction away from the printing roller 5, the spacing between the heating printing head 3 and the printing roller 5 is the first spacing d, and d satisfies: 15mm≥d≥5mm.

[0042] Optionally, when the printing head seat 2 moves to the maximum spacing position in the direction away from the printing roller 5, the first spacing d between the heating printing head 3 and the printing roller 5 satisfies: 15mm≥d≥5mm.

[0043] ​It can be understood that the heating print head 3 and the printing roller are used for the wire channel 6 for the wire tube 4 to pass the wire, if the wire channel 6 is too narrow, the wire tube 4 is not easy to pass the wire, even many radial size larger wire tube 4 cannot enter the wire channel 6, so that only small tube diameter wire tube 4 can pass, which limits the types of wire tube 4 that the wire tube printer 100 can print, resulting in that the first distance d cannot be too small; if the wire channel 6 is too large, the user's hand is easy to stretch into the wire channel 6 to contact the heating print head 3 and be scalded, resulting in that the first distance d also cannot be too large, so when d satisfies: 15mm≥d≥5mm, the wire channel 6 can allow most specifications of the wire tube 4 to pass, and the user's hand is not easy to stretch into the wire channel 6 and be scalded.

[0044] Please refer to Figure 4 , along the wire direction perpendicular to the wire tube 4, the height of the second part 22 is h, h satisfies: 20mm≥h≥5mm.

[0045] Optionally, the first part 21 and the second part 22 can be arranged along the wire direction perpendicular to the wire tube 4, and the first part 21 is located below the second part 22, so that the second part 22 can prevent the user's hand from stretching into the wire channel 6 to contact the heating print head 3.

[0046] It can be understood that the height of the second part 22 cannot be too small, when the height of the second part 22 is less than 5mm, the distance between the top surface of the second part 22 and the heating print head 3 will be small, the user is still easy to touch the heating print head 3, and the user is still at risk of being scalded, and the height of the second part 22 cannot be too large, when the height of the second part 22 is greater than 20mm, the distance between the top surface of the second part 22 and the heating print head 3 will be too large, although it can prevent the user from touching the heating print head 3, but the second part 22 will be redundant, which will increase unnecessary material cost, and the height of the second part 22 is too large, which will also affect the closure of the upper cover of the main machine 1, resulting in that the upper cover of the main machine 1 cannot be closed.

[0047] Therefore, the height h of the second part 22 satisfies: 20mm≥h≥5mm, which is the most appropriate, which can prevent the user from touching the heating print head 3, and can avoid waste of materials.

[0048] Please refer to Figure 5 , in some embodiments, the heating print head 3 includes a heating wire 31, the heating wire 31 extends along the wire direction perpendicular to the wire tube 4, and the first part 21 has an inlet tube side and an outlet tube side, the inlet tube side and the outlet tube side are arranged along the wire direction of the wire tube 4, and the heating wire 31 is located between the inlet tube side and the outlet tube side.

[0049] Optionally, the heating wire 31 is a component in the heating print head 3 capable of providing heat, and the heating wire 31 is responsible for converting electrical energy into heat energy, when the current passes through the heating wire 31, the heating wire 31 will heat up due to the resistance effect, and the heat is then transferred to the printing material on the surface of the heating print head 3, thereby achieving the printing of the image.

[0050] It can be understood that, during printing, the area provided with the heating wire 31 is the area with the highest temperature, and is also the area most needed to prevent the user from touching, and the heating wire 31 is arranged between the inlet pipe side and the outlet pipe side, so that the heating wire 31 is spaced apart from the opposite sides of the first part 21, thereby preventing the user from directly touching the area provided with the heating wire 31, and further reducing the risk of the user being scalded.

[0051] Further, please refer to Figure 4 In some embodiments, the distance between the heating wire 31 and the outlet pipe side is less than the distance between the heating wire 31 and the inlet pipe side.

[0052] It should be noted that the inlet pipe side of the print head seat 2 has an inlet pipe opening, and the outlet pipe side of the print head seat 2 has an outlet pipe opening, in order to make the wire number pipe 4 more smoothly enter the wire running channel 6, the size of the inlet pipe opening is generally larger than that of the outlet pipe opening, and accordingly the user is more likely to stretch his hand from the inlet pipe opening to the heating wire 31, and there is not so much space for the user to stretch his hand from the outlet pipe side to the heating wire 31, therefore, arranging the heating wire 31 closer to the outlet pipe side can further reduce the risk of the user being scalded.

[0053] Please refer to Figure 4 In some embodiments, the distance between the heating wire 31 and the inlet pipe side is L, and L satisfies: 25mm≥L≥15mm.

[0054] It can be understood that the distance L between the heating wire 31 and the inlet pipe side cannot be too small, when the distance L is less than 15mm, the distance between the heating wire 31 and the inlet pipe side is not enough to prevent the user from touching the heating wire 31, the user's hand can stretch from the inlet pipe opening to the heating wire 31, and the user still has the risk of being scalded; when the distance L is greater than 25mm, although it can prevent the user from touching the heating wire 31 from the inlet pipe side, it will cause the width of the first part 21 to be too large, increase the friction between the print head seat 2 and the wire number pipe 4, affect the normal wire running of the wire number pipe 4, and also cause waste of materials, therefore, L satisfies: 25mm≥L≥15mm is the most appropriate.

[0055] Please refer to Figure 2 In some embodiments, the host 1 has a support surface 11, the heating print head 3 and the support surface 11 form a wire running channel 6 for the wire number pipe 4 to run, and the distance between the top end of the heating wire 31 and the support surface 11 is a, and a satisfies: 20mm≥a≥8mm.

[0056] Optionally, the outer surface of the host 1 can have a support surface 11, which can be used to support the line number tube 4, and the support surface 11 is located on the side of the heating print head 3 away from the print head base 2, and the plane where the support surface 11 is located is arranged to intersect the heating print head 3, so that a wire running channel 6 can be formed between the heating print head 3 and the support surface 11, and when the line number tube 4 is located in the wire running channel 6, the support surface 11 can be supported below the line number tube 4, and the heating print head 3 can be used to print the line number tube 4.

[0057] It should be noted that the distance a between the top end of the heating wire 31 and the support surface 11 cannot be too large or too small. When the distance a is greater than 20 mm, the overall height of the print head base 2 is also greater than 20 mm, and the second part 22 of the print head base 2 also needs to prevent the user from touching the heating wire 31, so the height of the print head base 2 is also greater than the distance a, which will cause the volume of the entire line number tube printer 100 to become larger. When the distance a is less than 8 mm, the area that can be heated by the heating print head 3 will be very small. For line number tubes 4 with larger diameters, part of the line number tube 4 may not be printed during printing, resulting in that only line number tubes 4 with smaller diameters can be printed. Therefore, when a satisfies 20 mm≥a≥8 mm, neither the volume of the entire line number tube printer 100 becomes too large, nor more line number tubes 4 of different diameter specifications can be printed.

[0058] Please refer to Figure 5 In some embodiments, the heating print head 3 includes a heat sink 32, which is arranged on the first part 21, and the heating wire 31 can be in heat exchange contact with the heat sink 32.

[0059] Optionally, the heat sink 32 can be in the shape of a square sheet structure, and the heat sink 32 is attached to the first part 21, and the heating wire 31 can be mounted on the heat sink 32, so that the heating wire 31 can exchange heat with the heat sink 32, thereby accelerating the heat dissipation of the heating wire 31 through the heat sink 32, so that the heating wire 31 can cool down quickly after printing, and the risk of the user being scalded can be further reduced.

[0060] Preferably, the heat sink 32 can be a ceramic heat sink 32. The ceramic material itself has a high thermal conductivity, which can more effectively transfer heat from the heating wire 31 to the surrounding air, improving the heat dissipation efficiency.

[0061] Further, in some embodiments, the print head base 2 can be made of a heat dissipation material, so that the print head base 2 can also accelerate the heat dissipation of the heating wire 31, and after printing, the cooling speed of the heating wire 31 can be further accelerated, and the risk of the user being scalded by accidentally touching the heating wire 31 can be reduced.

[0062] Please refer to Figure 4 In some embodiments, the height of the second portion 22 is less than the height of the first portion 21 along a direction perpendicular to the wire direction of the wire tube 4.

[0063] Optionally, the first portion 21 is used as a part of the print head carrier 2 for mounting the thermal print head 3, the second portion 22 is located above the first portion 21, the second portion 22 can prevent the user from directly touching the thermal print head 3, the height of the second portion 22 is less than the height of the first portion 21, which can reduce the material and reduce the cost.

[0064] Please refer to Figure 5 In some embodiments, the first portion 21 has a mounting surface 211, the mounting surface 211 is provided with a limiting groove 212, and the thermal print head 3 is arranged in the limiting groove 212.

[0065] Optionally, the mounting surface 211 is a side surface of the first portion 21 facing the print roller 5, the mounting surface 211 can be provided with the limiting groove 212, the slot of the limiting groove 212 is arranged in a direction facing the print roller 5, and the limiting groove 212 can also penetrate the lower end of the first portion 21, so that the thermal print head 3 can be inserted into the limiting groove 212 from the lower end of the first portion 21, and the thermal print head 3 can be arranged from the slot of the limiting groove 212 towards the print roller 5, and the limiting groove 212 can facilitate the installation of the thermal print head 3.

[0066] Further, please refer to Figure 5 In some embodiments, the mounting surface 211 is provided with a first limiting block 213 and a second limiting block 214, the first limiting block 213 and the second limiting block 214 are arranged in a spaced manner along the wire direction of the wire tube 4, and the limiting groove 212 is formed between the first limiting block 213 and the second limiting block 214.

[0067] Optionally, the mounting surface 211 can be provided with the first limiting block 213 and the second limiting block 214 in a direction facing the print roller 5, and the first limiting block 213 and the second limiting block 214 are arranged in a spaced manner along the wire direction of the wire tube 4, and the first limiting block 213 and the second limiting block 214 are both extended along a direction perpendicular to the wire direction of the wire tube 4, so that the limiting groove 212 can be formed between the first limiting block 213 and the second limiting block 214, which can facilitate the installation of the thermal print head 3.

[0070] Please refer to Figure 5 Figure 5 In some embodiments, the first limiting block 213 and the second limiting block 214 are both provided with arc-shaped guide surfaces 215, which can be used to guide the wire number pipe 4 to move along the wire routing direction.
