Printing device

Abstract

This application discloses a printing device, comprising a main body, a printer, and a support mechanism. The printer is mounted on the main body, and the support mechanism includes a support member comprising two first support elements. The two first support elements are spaced apart to suspend a portion of the tape above the two first support elements. The gap between the printer and the two first support elements corresponds to the printing of the suspended portion of the tape between the two first support elements. By suspending the tape during printing, the printing device achieves pressure balance between the upper and lower surfaces of the ink when the tape is made of a breathable material, reducing ink penetration and effectively preventing blurring of patterns and text on tapes made of non-breathable materials. Furthermore, this suspended printing method is also applicable to tapes made of non-breathable materials, meeting more application needs.

Description

Technical Field

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

[0002] Many industries, such as packaging and decoration, require printed products. Printed products are usually produced by printing equipment, that is, the material tape is carried on a carrier platform opposite the printer of the printing equipment, and the printer sprays ink onto the material tape to form a preset pattern or text on its surface.

[0003] This printing method is mostly used for processing tapes made of non-breathable materials. When printing on tapes made of breathable materials, the air pressure on the ink surface is uneven due to the support of the platform. That is, the air pressure above the ink is greater than the air pressure below the ink. This makes it easier for the ink to penetrate downwards through the pores of the breathable material, resulting in blurred patterns or text and affecting the quality of the finished product. Utility Model Content

[0004] To address the aforementioned technical problems and achieve at least one advantage of this application, this application provides a printing apparatus, the printing apparatus comprising:

[0005] Equipment body;

[0006] A printer, which is mounted on the main body of the device;

[0007] The carrier mechanism includes a carrier member, which includes two first carrier elements. The two first carrier elements are spaced apart to keep a portion of the tape taut and positioned above the two first carrier elements suspended. The gap between the printer and the two first carrier elements corresponds to the printer printing the suspended portion of the tape located between the two first carrier elements.

[0008] According to one embodiment of this application, the supporting member further includes a second supporting member located between the two first supporting members. The first supporting member and the second supporting member can be raised and lowered arbitrarily to support a material strip by one of them. When the first supporting member and the second supporting member are raised and lowered arbitrarily so that the top end of the first supporting member is higher than the top end of the second supporting member, the material strip implemented as a breathable material is supported by the first supporting member. When the first supporting member and the second supporting member are raised and lowered arbitrarily so that the top end of the second supporting member is not lower than the top end of the first supporting member, the material strip implemented as a non-breathable material is supported by the second supporting member.

[0009] According to one embodiment of this application, the top wall of the second carrier is formed with a plurality of vertically penetrating adsorption holes, and the second carrier is connected to a vacuum device through a pipe to adsorb and fix the material strip, which is implemented as an airtight material, by using negative pressure adsorption.

[0010] According to one embodiment of this application, the printing device further includes two material fixing mechanisms, which are respectively located on both sides of the two first carriers to fix the two ends of the suspended portion of the material strip between the two first carriers. The height of the portion of the material strip fixed by the material fixing mechanism is not higher than the height of the portion of the material strip supported by the first carrier or the second carrier.

[0011] According to one embodiment of this application, the printing device further includes a dryer, which is located in the direction in which the material belt continues to be conveyed as it passes under the printer and corresponds to one side of the material belt. The dryer is used to dry the portion of the material belt that has been printed.

[0012] According to one embodiment of this application, the printing device further includes a take-up mechanism, which includes a take-up roller located in the direction in which the material strip moves past the outside of the dryer and continues to be driven. The take-up roller is rotatably mounted on the main body of the device and is used to assemble a roll. When the take-up roller is driven to rotate, it drives the roll to rotate to take up the portion of the material strip that has been dried.

[0013] According to one embodiment of this application, the printing device further includes an auxiliary take-up mechanism, which includes an auxiliary take-up member adjacent to the take-up roller. The auxiliary take-up member is used to press one end of the conveyed strip moved to the side of the take-up roller against the surface of the roll mounted on the take-up roller. When the side of the strip end facing the take-up roller and the outer periphery of the roll are pre-coated with adhesive, the auxiliary take-up member applies pressure to the strip end to make the strip end adhere to the roll.

[0014] According to one embodiment of this application, the auxiliary receiving component includes a material-applying roller and at least one material-applying drive member. The material-applying roller is adjacent to the receiving roller and parallel to the axial direction of the receiving roller. The end of the material strip that is conveyed to the receiving roller from outside the dryer is placed between the material-applying roller and the receiving roller. The material-applying roller is mounted on the material-applying drive member and is driven by the material-applying drive member to move closer to or away from the receiving roller. When the material-applying roller is driven to move closer to the receiving roller, the end of the material strip is pressed by the material-applying roller against the surface of the roll mounted on the receiving roller.

[0015] According to one embodiment of this application, the auxiliary receiving mechanism further includes a monitoring element, which is used to radiate a signal to the area between the take-up roller and the application roller to detect whether the end of the material strip extends to the side of the take-up roller. The monitoring element is communicatively connected to a controller, and the controller is controlled to be connected to the application drive. When the monitoring element detects the end of the material strip, the application drive is controlled by the controller to operate and push the application roller to move closer to the take-up roller, so as to press the end of the material strip onto the surface of the roll assembled on the take-up roller.

[0016] According to one embodiment of this application, the printing device further includes a tension adjustment mechanism, which is installed in the direction in which the material belt moves through the dryer and is conveyed toward the take-up roller. The tension adjustment mechanism is used to adjust the tension of the material belt conveyed toward the take-up roller. Attached Figure Description

[0024] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] refer to Figures 1 to 3 A preferred embodiment of the printing apparatus according to this application will be described in detail below. The printing apparatus includes a main body 10, a printer 20, and a support mechanism 30, with the printer 20 mounted on the main body 10. The support mechanism 30 includes a support member 31, which includes two first support elements 311. The two first support elements 311 are spaced apart to keep the tensioned material strip portion suspended above the two first support elements 311. The printer 20 corresponds to the gap between the two first support elements 311 to print the suspended portion of the material strip between the two first support elements 311. In this way, by suspending the material strip during printing, the printing apparatus ensures that the air pressure on the ink surface of the material strip is balanced when the material strip is made of a breathable material, reducing ink penetration and effectively preventing blurring of patterns and text formed on the surface of a material strip made of an impermeable material. In addition, this suspended printing method is also applicable to material strips made of impermeable materials, meeting more usage needs.

[0028] refer to Figures 2 to 5 Furthermore, the supporting member 31 also includes a second supporting member 312, which is located between the two first supporting members 311. The first supporting member 311 and the second supporting member 312 can be raised and lowered arbitrarily to support the material strip by one of them. When the first supporting member 311 and the second supporting member 312 are raised and lowered so that the top end of the first supporting member 311 is higher than the top end of the second supporting member 312, the material strip, which is made of breathable material, is supported by the first supporting member 311; when the first supporting member 311 and the second supporting member 312 are raised and lowered so that the top end of the second supporting member 312 is not lower than the top end of the first supporting member 311, the material strip, which is made of impermeable material, is supported by the second supporting member 312.

[0029] The supporting mechanism 30 includes at least one set of lifting drive members 32, wherein the first supporting member 311 and the second supporting member 312 are arbitrarily installed on the lifting drive members 32 so as to be driven by the lifting drive members 32 to rise and fall.

[0030] Preferably, two sets of lifting drive members 32 are provided, and each set of lifting drive members 32 has multiple members. The multiple lifting drive members 32 in one set are arranged at intervals along a direction parallel to the length direction of the first support member 311. Each first support member 311 is installed on a set of lifting drive members 32 to be driven to rise and fall by the corresponding lifting drive member 32. When the first support member 311 is driven by the corresponding lifting drive member 32 to descend so that its top end is not higher than the top end of the second support member 312, the material strip implemented as an impermeable material is supported by the second support member 312; when the first support member 311 is driven by the corresponding lifting drive member 32 to rise so that its top end is higher than the top end of the second support member 312, the material strip implemented as a breathable material is supported by the first support member 311.

[0031] Preferably, the lifting drive 32 is implemented as a cylinder.

[0032] The first carrier 311 includes a carrier portion 3111 and a connecting portion 3112. The length of the carrier portion 3111 is not less than the width of the material strip. The connecting portion 3112 is installed on the lifting drive 32. The carrier portion 3111 is detachably installed on the connecting portion 3112 so as to accommodate material strips with a wider width range by replacing the carrier portion 3111 of different lengths.

[0033] It is worth mentioning that the top wall of the second carrier 312 has a plurality of vertically penetrating adsorption holes 31201. The second carrier 312 is connected to a vacuum device through a pipe to adsorb and fix the material strip, which is implemented as an airtight material, by using negative pressure adsorption.

[0034] The printing device further includes two material securing mechanisms 40, which are respectively located on both sides of the two first support members 311 to fix the two ends of the material strip located in the suspended portion between the two first support members 311. The height of the portion of the material strip fixed by the material securing mechanisms 40 is not higher than the height of the portion of the material strip supported by the first support member 311 or the second support member 312. During the printing process, the two ends of the suspended portion of the material strip between the two first support members 311 are fixed by the two material securing mechanisms 40 to prevent it from moving, thus ensuring the printing quality.

The pressing roller 411 of each pressing assembly 41 can press the conveyed material strip that is moved between it and the material supporting roller 42 against the material supporting roller 42 to fix one end of the material strip located in the suspended portion between the two first bearing members 311 together with the material supporting roller 42.

[0036] Preferably, the pressure roller 411 is rotatably mounted on one end of the connecting frame 412. The connecting frame 412 is rotatably mounted on the equipment body 10 such that the end of the connecting frame 412 on which the pressure roller 411 is mounted is close to or away from the support roller 42 to adjust the distance between the pressure roller 411 and the support roller 42, thereby satisfying the need to fix material strips of different thicknesses. In addition, the pressure assembly 41 also includes an elastic member 43. The two ends of the elastic member 43 correspond to the connecting frame 412 and the equipment body 10, respectively. The elastic member 43 can apply pressure to the connecting frame 412 to keep the pressure roller 411 mounted on one end of the connecting frame 412 pressed against the surface of the support roller 42, so as to firmly fix the two ends of the material strip located in the suspended portion between the two first support members 311.

[0037] Preferably, the elastic element 43 is implemented as a torsion spring, which is sleeved on the pivot of the connecting frame 412 and its two ends are respectively connected to the connecting frame 412 and the equipment body 10.

[0038] Preferably, each of the material-fixing mechanisms 40 has multiple pressing components 41, and the multiple pressing components 41 are spaced apart along the axial direction of the material support roller 42, so that the multiple pressing components 41 cooperate with the material support roller 42 to firmly fix the end of the suspended portion of the material strip located between the two first carrier members 311.

[0039] Preferably, the printer 20 is movable in a direction parallel to the axial direction of the pressure roller 411 to print at different positions in the width direction of the suspended portion of the strip between the two first carriers 311, thereby achieving full-coverage printing.

The auxiliary take-up member 71 is used to press one end of the conveyed material strip moved to the side of the take-up roller 61 against the surface of the roll mounted on the take-up roller 61. When the side of the material strip facing the take-up roller 61 and the outer periphery of the roll are pre-coated with adhesive, the auxiliary take-up member 71 applies pressure to the end of the material strip to make the end of the material strip adhere to the roll. At this time, there is no need to manually wrap the end of the material strip around the surface of the roll, increasing the convenience of material take-up.

[0051] The printing device also includes a tension adjustment mechanism 80, which is installed in the direction in which the material belt moves through the dryer 50 and is conveyed toward the take-up roller 61. The tension adjustment mechanism 80 is used to adjust the tension of the material belt conveyed toward the take-up roller 61 to ensure that the material belt remains taut and wound around the drum.

[0052] The tension adjustment mechanism 80 includes a tension roller 81, which is located in the direction in which the material belt moves through the dryer 50 and is conveyed to the take-up roller 61 and corresponds to one side of the material belt. The tension roller 81 can be controlled to press against the material belt to adjust its direction, thereby adjusting the tension of the material belt that moves through the dryer 50 and is conveyed to the take-up roller 61.
