Description

Technical Field

[0001] The utility model relates to the technical field of digital fabric printing equipment, in particular to a heating and shaping structure suitable for a printing machine. Background Art

[0002] A digital printing machine is a device used to spray patterns on fabrics. After the dye is sprayed onto the fabric, the fabric is transferred to a drying area for drying.

[0003] In the process of transferring the fabric to dry, there are the following defects:

[0004] 1. The dye on the fabric has not yet dried completely and may smudge during the transfer process;

[0005] 2. Drying is usually done without heating or by relying on external heating. If external heating is used, a lot of energy consumption is required, which increases production costs. If no heating is used, production time is prolonged. Utility Model Content

[0006] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a printing machine with a rational structure and a heating and shaping structure suitable for use. During the time interval of the printing process, the printed fabric on the roller is quickly and evenly heated, eliminating the subsequent separate heating step and improving production efficiency.

[0007] The technical solutions adopted in this utility model are as follows:

[0008] A heating and shaping structure suitable for a printing machine includes a roller body extending outside a machine housing and a heat delivery component located inside the machine housing, wherein the roller serves as both a fabric positioning member and a heating member;

[0009] The roller body is formed with a hot air delivery channel, and the heat delivery component includes an air inlet pipe connected to the hot air delivery channel and an external heat source connected to the air inlet pipe. The heat source provides continuous or intermittent heat.

[0010] The hot gas transport channel comprises:

[0011] The air inlet is located at the end of the roller near the equipment.

[0012] The reinforcing ribs are located on the inner wall of the hot air conveying channel. The reinforcing ribs are straight or curved. The hot air conveying channel is fully connected or divided into several chambers by the reinforcing ribs.

[0013] The air outlet holes are evenly distributed on the outer surface of the roller.

[0014] As a further improvement of the above technical solution:

[0015] One end of the roller extending out of the casing is a closed end.

[0016] The diameter of the roller's air inlet is smaller than the diameter of the hot air conveying channel.

[0017] The reinforcing ribs are arranged along the inner wall of the roller, and the axial length of the reinforcing ribs is the same as the axial length of the roller.

[0018] The cross section of the reinforcement rib is wedge-shaped, and the small end of the reinforcement rib cross section faces the roller axis.

[0019] The heat source adopts an air pump and a heating wire, and the flow rate of the hot air output by the heat source is accelerated twice through the air inlet and the air outlet.

[0020] The air outlet is an inclined hole, and the air flow output direction of the air outlet is toward the casing.

[0021] Each intake pipe is equipped with an independent valve.

[0022] The beneficial effects of the utility model are as follows:

[0023] The utility model has a compact and reasonable structure and is easy to operate. The roller is used as a fabric positioning member and a heating member. The heating and drying part of the equipment does not affect the loading and unloading of the fabric, the printing and displacement of the printing structure at all. That is, on the basis of the original printing, it does not affect any printing efficiency and directly omits the subsequent drying process, thereby greatly shortening the production time.

[0024] When there are many roller groups, one group can be printed and the other group can be dried, and the materials can be loaded and unloaded alternately to ensure that printing and drying actions are carried out synchronously in each time period and the processing rhythm is stable and coherent.

[0031] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0032] like Figure 1-Figure 3As shown, the printing machine of this embodiment is suitable for a heating and setting structure, including a roller 1 body extending outside the casing and a heat supply component located inside the casing. The roller 1 serves as both a fabric positioning member and a heating member.

[0033] A hot air delivery channel 101 is formed within the roller body 1. The heat delivery assembly includes an air inlet pipe 2 connected to the hot air delivery channel 101 and an external heat source connected to the air inlet pipe 2. The heat source can provide heat continuously or intermittently. Continuous heat supply ensures the roller 1 maintains its own temperature, effectively preheating it. Intermittent heat supply consumes less energy and can be selected based on actual operating conditions.

[0034] The hot gas transport channel 101 includes:

[0035] The air inlet 102 is located at the end of the roller 1 close to one end of the device.

[0036] The reinforcing ribs 103 are located on the inner wall of the hot air delivery channel 101. The reinforcing ribs 103 are straight or curved. The hot air delivery channel 101 is completely connected or divided into several chambers by the reinforcing ribs 103.

[0037] The air outlet holes 104 are evenly distributed on the outer surface of the roller 1 .

[0038] The end of the roller 1 extending out of the casing is a closed end.

[0039] The diameter of the air inlet 102 of the roller 1 is smaller than the diameter of the hot air conveying channel 101 .

[0040] The reinforcing ribs 103 are arranged along the inner wall of the roller 1 , and the axial length of the reinforcing ribs 103 is the same as the axial length of the roller 1 .

[0041] The cross section of the reinforcing rib 103 is wedge-shaped, and the small end of the cross section of the reinforcing rib 103 faces the axis of the roller 1 .

[0042] The heat source adopts an air pump and a heating wire, and the flow rate of the hot air output by the heat source is accelerated twice through the air inlet 102 and the air outlet 104.

[0043] The air outlet 104 is an oblique hole, and the air flow output direction of the air outlet 104 is toward the housing.

[0044] Each air intake pipe 2 is equipped with an independent valve 201 .

[0045] The specific structure and working principle of the utility model are as follows:

[0046] The purpose of this utility model is to provide a heating and drying mechanism that can be used simultaneously with printing on a printing machine. External or additional heating and drying mechanisms can easily interfere with loading and unloading, as well as printing, due to layout issues. Therefore, this utility model improves the roller 1, which originally served only as a fabric positioning member, into a roller 1 with a heating function. This roller 1 generates heat energy after or during printing, accelerating fabric drying. After drying, the fabric can be collected and directly sent to the packaging and storage process, significantly reducing processing time.

[0047] Taking socks as an example, the socks are put on roller 1, and after printing is completed, roller 1 immediately starts to heat and dry; alternatively, during the printing process, roller 1 can control the airflow size through valve 201, preheating roller 1 without affecting printing, thereby accelerating the subsequent drying speed.

[0048] like Figure 3 As shown, to minimize impact on the printhead, only the roller 1 protrudes from the exterior of the housing. The air inlet pipe 2 and heat source attached to the end of the roller 1 are concealed within the housing. The heat source can utilize existing structures. For example, a heating wire is powered, and an air pump blows air, delivering heat-carrying air through the air inlet pipe 2 and into the hot air delivery channel 101 of the roller 1. Valves 201 on each air inlet pipe 2 effectively control which rollers 1 are allowed to generate heat.

[0049] like Figure 2 As shown, the air inlet 102 of the roller 1 adopts a smaller diameter, so that the air flow can increase the flow rate when entering the hot air conveying channel 101 and quickly enter the interior of the roller 1.

[0050] like Figure 1 As shown, the present invention incorporates multiple reinforcing ribs 103 within the roller 1. These ribs serve two purposes: firstly, they enhance the overall strength of the roller 1; secondly, they increase the heat exchange area, enabling rapid heat conduction and improving heating and drying efficiency. During the heating process, the roller 1 generates its own heat, while air outlets 104 simultaneously release air, accelerating drying.

[0051] As an optional embodiment, the reinforcing ribs 103 can also divide the hot air conveying channel 101 into several chambers, and the volume of the chambers is smaller, which is conducive to accelerating the air flow.

[0052] The outlet holes 104 of the hot air delivery channel 101 can be straight or inclined, with the inclined holes facing the housing to reduce the probability of accidental burns to the operator. The protruding end of the roller 1 is designed as a closed end, also to prevent the hot air from being ejected toward the operating side and causing harm.

[0053] When the airflow passes through the air outlet 104, it is accelerated again, taking away moisture more quickly and completing the drying.

[0054] The greatest advantage of the present invention is that the structure extending out of the casing does not have any additional structure, which will not affect the printing of the nozzle and manual loading and unloading of materials; during the printing process, when one group of fabrics is being printed, the other group of fabrics is being dried and loaded and unloaded; when the nozzle printing is completed and transferred to another group of fabrics to be printed, the printed fabrics are dried, unloaded, and new fabrics to be printed are loaded, thereby realizing alternating work and effectively improving work efficiency.

[0055] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
