Description

Technical Field

[0001] This utility model belongs to the field of product packaging technology, and in particular relates to a printing drying device and printing equipment. Background Technology

[0002] In the fields of flexible packaging materials, label printing, electronic product accessory packaging, and pharmaceutical and daily chemical product packaging, ink is sprayed onto the product surface through inkjet printing equipment (such as roll-to-roll machines) during the product manufacturing process to form a pre-set identification structure such as text, numbers, and graphics.

[0003] In existing technologies, the ink used in inkjet printing equipment is liquid. When this liquid ink is sprayed onto the product surface, incomplete drying can lead to insufficient adhesion of the printed information, resulting in blurred markings, smudging, or peeling. Currently, the industry commonly uses a drying method where the machine is stopped and allowed to air dry naturally before restarting. This method not only significantly reduces production efficiency but also exacerbates equipment wear and tear due to repeated start-ups and shutdowns, affecting the continuity and stability of the production process.

[0004] Therefore, there is an urgent need for a printing drying device and printing equipment to solve the above problems. Utility Model Content

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] Example 1

[0043] like Figures 1 to 4 As shown, this embodiment provides a printing drying device 100, which can quickly dry the printing, not only ensuring the quality of the printing, but also significantly improving the continuity and stability of the coding operation.

[0044] See Figure 1 The inkjet drying device 100 is used for drying inkjet printing and includes a support 110, an air supply assembly 120 and a heating element 130. The air supply assembly 120 is disposed on the support 110 and is used to blow air to the inkjet printer. The heating element 130 is disposed on the support 110 and connected to the air supply assembly 120 and is used to heat the air passing through the air supply assembly 120.

[0045] The inkjet drying apparatus 100 provided in this embodiment uses an air supply assembly 120 to blow air to the printing area, which accelerates the airflow velocity on the printing surface, thereby speeding up the inkjet drying process. The heating element 130 heats the air within the air supply assembly 120, ensuring that the air blown to the printing area is hot air, further accelerating the drying process. This not only guarantees the quality of the inkjet print but also significantly improves the efficiency of the coding operation. Compared with existing technologies, this inkjet drying apparatus 100 achieves rapid inkjet drying without requiring the printing equipment to be shut down, improving the continuity and stability of the coding operation.

[0046] In this embodiment, before the inkjet printer moves to the air supply end of the air supply assembly 120, the heating element 130 heats the air inside the air supply assembly 120 so that when the inkjet printer moves to the air supply end of the air supply assembly 120, the air supply assembly 120 can blow out hot air, reducing the time for the inkjet printer to wait for the air to heat up, which helps to further accelerate the inkjet drying rate and improve the efficiency of the coding operation.

[0047] For example, this embodiment can reduce the drying time of the inkjet print by at least 3 seconds.

[0048] Optionally, see Figure 1 and Figure 2 The inkjet drying apparatus 100 also includes a temperature measuring element 140 disposed on the support 110. The temperature measuring element 140 is used to monitor the temperature of the heating element 130 to prevent the temperature of the heating element 130 from becoming too high, thereby improving the safety of the inkjet drying apparatus 100. Moreover, by observing the temperature value obtained by the temperature measuring element 140, it is also possible to determine whether the heating element 130 is in a normal operating state, thereby improving the ease of use of the inkjet drying apparatus 100.

[0049] Specifically, when the temperature of the heating element 130 is measured by the temperature measuring element 140 to be higher than the preset temperature, the heating temperature of the heating element 130 can be appropriately lowered to ensure the safety of use; when the temperature of the heating element 130 is measured by the temperature measuring element 140 to be much lower than the preset temperature, the heating temperature of the heating element 130 can be appropriately raised to ensure the heating effect of the heating element 130 on the air.

[0050] The preset temperature is the temperature at which the heating element 130 can operate normally, and is specifically determined according to the type of heating element 130 used and the surrounding environment of the heating element 130.

[0051] For example, in this embodiment, the heating element 130 adopts an electric heating structure with a preset temperature of 70 degrees.

[0052] In this embodiment, the temperature sensing element 140 is a platinum resistance thermometer. The resistance value of the platinum resistance thermometer changes linearly with temperature, and the temperature of the heating element 130 can be accurately obtained by observing the resistance value of the platinum resistance thermometer. When the temperature of the heating element 130 increases, the resistance value of the platinum resistance thermometer increases; when the temperature of the heating element 130 decreases, the resistance value of the platinum resistance thermometer decreases.

[0053] In other embodiments, the temperature measuring element 140 is a thermometer.

[0054] In this embodiment, the inkjet drying apparatus 100 further includes a control component, which is electrically connected to both the temperature measuring component 140 and the heating component 130, and is used to control the heating temperature of the heating component 130. The temperature measuring component 140 can transmit the measured temperature to the control component via an electrical signal. The control component can control the heating temperature of the heating component 130 according to the acquired electrical signal, thereby realizing automatic control of the heating operation of the heating component 130. This ensures the safety of the drying operation and also improves the automation level of inkjet drying.

[0055] For example, the heating element 130 adopts an electric heating structure, such as an electric heating rod or resistance wire, and the control element controls the heating temperature of the heating element 130 by controlling the power of the heating element 130.

[0056] Optionally, see Figure 3 The heating element 130 includes an electric heating rod 131 and an insulating sleeve 132 fitted over the electric heating rod 131. The electric heating rod 131 is configured to convert electrical energy into heat energy to heat the air. The insulating sleeve 132 not only effectively blocks the conduction of electrical energy from the electric heating rod 131 to prevent electric shock accidents, but also focuses the direction of heat transfer, reducing heat loss to non-heating directions and improving the heating effect.

[0057] In this embodiment, see Figure 3 The temperature measuring element 140 is disposed on the insulating sleeve 132 so that the temperature measuring element 140 can accurately measure the temperature of the heating element 130 and will not be damaged by the heating element 130.

[0058] Optionally, see Figure 4 The support 110 is provided with a heating channel 1111. The air supply assembly 120 includes a first air supply pipe 121, the inner cavity of which is connected to the heating channel 1111. The heating element 130 is at least partially located in the heating channel 1111. Unheated air enters the heating channel 1111 and is heated by the heating element 130 within the heating channel 1111. The heated air then flows from the heating channel 1111 into the first air supply pipe 121 and is blown onto the printing surface to dry the printing process.

[0059] For example, the first air supply duct 121 is made of a high-temperature resistant material to prevent hot air from damaging the first air supply duct 121.

[0060] In this embodiment, see Figure 4 The support 110 is provided with an air inlet. The heating channel 1111 includes a first channel segment 11111, a second channel segment, and a third channel segment 11112 connected in sequence. The first channel segment 11111 and the third channel segment 11112 are respectively located on both sides of the insulating sleeve 132. The second channel segment extends circumferentially along the insulating sleeve 132. The first channel segment 11111 is connected to the air inlet, and the third channel segment 11112 is connected to the inner cavity of the first air supply pipe 121. Air enters the first channel segment 11111 through the air inlet, and then enters the third channel segment 11112 through the second channel segment, and finally enters the first air supply pipe 121 through the third channel segment 11112. The air can be heated in the first channel segment 11111, the second channel segment, and the third channel segment 11112, which prolongs the path of air heating and helps to improve the efficiency of air heating.

[0061] Specifically, see Figure 4 The insulating sleeve 132 is provided with several grooves 1321, which are connected to the second channel section. Air in the second channel section can flow into the grooves 1321, thereby getting closer to the electric heating rod 131 and further improving the efficiency of air heating.

[0062] For example, see Figure 4 Multiple grooves 1321 are provided, and the multiple grooves 1321 are arranged at intervals along the direction of air flow in the support 110 to improve the heating effect.

[0063] In this embodiment, see Figure 4 The support 110 is provided with an air inlet communicating with the heating channel 1111. A first connector 1112 is provided at the air inlet. The air supply assembly 120 also includes a second air supply pipe that is detachably connected to the first connector 1112. When the first connector 1112 is connected to the second air supply pipe, the inner cavity of the second air supply pipe is connected to the air inlet through the first connector 1112. When the first connector 1112 is separated from the second air supply pipe, the air inlet is blocked by the first connector 1112 to prevent air from leaking out of the heating channel 1111. When printing heating is not required, the second air supply pipe can be separated from the first connector 1112 to prevent the second air supply pipe from affecting other processes.

[0064] For example, the first connector 1112 is a pipe fitting.

[0065] In this embodiment, see Figure 4The support 110 is also provided with an air outlet communicating with the heating channel 1111. A second connector 1113 is provided at the air outlet. The first air supply pipe 121 and the second connector 1113 can be detachably connected. When the second connector 1113 is connected to the first air supply pipe 121, the inner cavity of the first air supply pipe 121 communicates with the air outlet through the second connector 1113. When the second connector 1113 is separated from the first air supply pipe 121, the air outlet is blocked by the second connector 1113 to prevent air from leaking out of the heating channel 1111. When printing heating is not required, the first air supply pipe 121 can be separated from the second connector 1113 to prevent the first air supply pipe 121 from affecting other processes.

[0066] For example, the second connector 1113 is a pipe fitting.

[0067] In this embodiment, the air supply assembly 120 further includes an air suction component disposed at the end of the second air supply pipe away from the air inlet, the air suction component being used to draw air into the second air supply pipe.

[0068] For example, the suction device is an electric fan, which rotates to create a negative pressure zone, and outside air is drawn into the second air supply duct.

[0069] In this embodiment, see Figure 4 The air supply assembly 120 also includes a blower 122 disposed at the end of the first air supply pipe 121 away from the heating channel 1111. The blower 122 is provided with an air passage communicating with the inner cavity of the first air supply pipe 121. The cross-sectional area of ​​the air passage is smaller than that of the first air supply pipe 121. According to the formula that the volumetric flow rate is equal to the product of the cross-sectional area and the flow velocity, it can be understood that the volume of air passing through the first air supply pipe 121 per unit time is fixed. When the air flows from the first air supply pipe 121 into the air passage, the cross-sectional area becomes smaller and the air velocity increases, which helps to further accelerate the printing and drying rate.

[0070] For example, the structure of the blower 122 is the same as that of the hair dryer head, which is the prior art in this field and will not be described in detail here.

[0071] Specifically, see Figure 4 The air supply assembly 120 also includes a third connector 123 disposed at the end of the first air supply pipe 121 away from the heating channel 1111. The first air supply pipe 121 can be detachably connected to the blower 122 through the third connector 123.

[0072] For example, the third connector 123 is a pipe fitting.

[0073] Optionally, see Figure 1The support 110 includes a mounting cylinder 111 and two sealing members 112. The two sealing members 112 are located at both ends of the mounting cylinder 111 and are detachably connected to the mounting cylinder 111. They are used to seal the opening of the mounting cylinder 111. The heating element 130 is at least partially located inside the mounting cylinder 111, and the air supply assembly 120 is connected to the mounting cylinder 111. This arrangement makes the inner cavity of the mounting cylinder 111 a sealed space. The air heated by the heating element 130 can only enter the air supply assembly 120 and will not overflow, thus improving the safety of the heating process. When the heating element 130 located inside the mounting cylinder 111 malfunctions, the sealing members 112 can be removed from the mounting cylinder 111 for repair and replacement of the heating element 130, making the operation convenient and quick.

[0074] Specifically, see Figure 1 and Figure 4 The insulating sleeve 132 is located inside the mounting cylinder 111, and the outer wall of the insulating sleeve 132 is sealed to the inner wall of the mounting cylinder 111. The air inlet and air outlet are both located on the cylinder wall of the mounting cylinder 111, and the heating channel 1111 is located inside the mounting cylinder 111.

[0075] For example, the sealing element 112 is a plate. The sealing element 112 is detachably connected to the mounting sleeve 111 by bolts or screws.

[0076] In this embodiment, the support 110 also includes a sealing element. The sealing element 112 is sealed to the mounting cylinder 111 through the sealing element to improve the sealing performance of the inner cavity of the mounting cylinder 111 and effectively prevent hot air from escaping.

[0077] Specifically, the sealing element is a sealing ring, which is sandwiched between the sealing element 112 and the mounting cylinder 111.

[0078] For example, the sealing ring is a rubber ring, which is glued or vulcanized to one of the sealing element 112 and the mounting cylinder 111.

[0079] In this embodiment, see Figure 2 The sealing element 112 has a through hole 1121, and a sealing sleeve 113 is disposed inside the through hole 1121. The outer wall of the sealing sleeve 113 is in sealing contact with the hole wall of the through hole 1121. The heating element 130 passes through the inner hole of the sealing sleeve 113 and is in sealing connection with the inner hole wall of the sealing sleeve 113. This arrangement further improves the sealing performance of the inner cavity of the mounting cylinder 111 and effectively prevents hot air from escaping.

[0080] For example, the sealing sleeve 113 is made of a high-temperature resistant material to prevent the heating element 130 from being damaged when heated.

[0081] Example 2

[0082] like Figures 1 to 6As shown, this embodiment provides a printing device, including a frame 200, a coding system 300, and a printing drying device 100 of Embodiment 1. The supports 110 of the coding system 300 and the printing drying device 100 are both disposed on the frame 200. The coding system 300 is used for inkjet printing.

[0083] For example, the printing equipment is a roll-to-roll machine.

[0084] In this embodiment, see Figure 6 The coding system 300 includes a scanning component 310, an exit pressure roller 320, and a printing terminal 330. The scanning component 310 is used to detect the coding quality; the exit pressure roller 320 ensures that the roll remains flat and stable during the coding process by rolling and pressing the roll, avoiding coding misalignment caused by substrate vibration or offset; the printing terminal 330 uses piezoelectric, thermal, or continuous inkjet technology to accurately spray ink onto the surface of the roll to form text, patterns, or identification codes (such as barcodes or QR codes).

[0085] Specifically, the specific structures of the barcode scanner 310, the export pressure roller 320, and the spray nozzle 330, as well as their installation methods on the frame 200, are all existing technologies in the field and will not be described in detail here.

[0086] In this embodiment, see Figure 5 The printing equipment also includes an encoder 410 and a buffer 420. The encoder 410 is mounted on the frame 200 and outputs a pulse signal proportional to the rotation speed in real time by detecting the movement speed of the inkjet nozzle 330. The buffer device (such as a buffer or register) is an intermediate storage area for data transmission.

[0087] Specifically, the specific structure of the encoder 410 and the buffer 420 and their mounting method on the rack 200 are existing technologies in the field and will not be described in detail here.

[0088] Optionally, see Figure 1 and Figure 5 The inkjet drying device 100 also includes a heat insulation component 150, which is disposed between the support 110 and the inkjet system 300 so that the support 110 and the inkjet system 300 can be spaced apart to prevent the heat generated by the heating element 130 from being transferred to the inkjet system 300 and affecting the normal operation of the inkjet system 300.

[0089] For example, the heat insulation element 150 adopts heat insulation columns, and several of them are provided between the support 110 and the inkjet system 300.
