Description

Technical Field

[0001] The utility model relates to the field of printing machines, and particularly to an efficient heating mechanism for a heat transfer printing machine. Background Art

[0002] With the continuous progress of technology and the rapid development of industrial production, the heat transfer printing machine, as an efficient and precise printing device, has been widely used in multiple fields. The heat transfer printing machine is mainly used to print patterns, texts, etc. onto various materials, and has a wide range of applications, including but not limited to industries such as clothing, home decoration, advertising media, and handicrafts. Its characteristics of high precision, high efficiency, low cost, and personalized customization are favored by the majority of users.

[0003] Among the core components of the heat transfer printing machine, the heating mechanism is an indispensable part, and its performance directly affects the quality and efficiency of printing. At present, most of the heating mechanisms of heat transfer printing machines on the market adopt traditional heating methods such as heating wires and heating tubes. Through electric heating, the heating roller or heating plate reaches the set temperature, and then the pattern is transferred from the transfer paper to the printed material. Specifically, the basic structure of the traditional heating mechanism includes parts such as heating elements, temperature sensors, and control circuits. The heating elements are responsible for generating heat, the temperature sensors monitor the temperature of the heating elements in real time, and transmit the temperature signals to the control circuit. The control circuit adjusts the heating power of the heating elements according to the temperature signals, so as to control the temperature of the heating roller or heating plate.

[0004] However, although the traditional heating mechanism meets the heating requirements of the heat transfer printing machine to a certain extent, there are still the following defects. The existing heating mechanism generally uses heating elements such as heating wires and heating tubes to heat the printing, and its heat conversion efficiency is relatively low. The traditional heating mechanism consumes a large amount of electric energy during the heating process, increasing the production cost. When heating the product, the existing heating mechanism has a slow heating rate and uneven temperature in the heating area, resulting in poor stability and consistency of the heating temperature of the heating mechanism for printing, thus affecting the production efficiency and the quality of the printed products. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above defects and provide an efficient heating mechanism for a heat transfer printing machine to solve the technical problems that the heating temperature stability and consistency of the heating mechanism for printing are poor, increasing the heating energy consumption, thus affecting the production efficiency and the quality of the printed products in the above background art.

[0006] The purpose of the utility model is achieved in the following way:

[0007] Efficient heating mechanism of thermal transfer printing machine, including a bottom beam bracket. A working platform is connected to the bottom beam bracket through a support seat. Machine boxes are arranged at both ends of the bottom beam bracket. The side of the machine box is connected to the bottom beam bracket through a wall panel. A rear housing is arranged on one side of the bottom beam bracket. The two ends of the rear housing are respectively installed in a wrapped manner on one side of the bottom beam bracket and the support seat, so that the rear housing, the bottom beam bracket, the wall panel and the support seat enclose a heat conduction cavity. A heat conduction hole communicating with the heat conduction cavity for injecting hot air is opened on one side of the wall panel. A heating element is connected to the heat conduction hole through a heat conduction pipe. A tensioner is arranged on the inner side surface of the wall panel connected to the rear housing. A feeding roller is connected to the tensioner. The feeding roller can move towards the outer side surface of the rear housing under the drive of the tensioner, and a heating roller is coaxially connected inside the feeding roller.

[0008] Further in the above description, a partition is connected to the side of the bottom beam bracket adjacent to the support seat, and the bottom beam bracket is connected to the support seat through a support frame. The partition, the rear housing, the bottom beam bracket, the wall panel and the support seat enclose a heat conduction cavity, so that the partition can prevent the hot air in the heat conduction cavity from escaping easily and enhance the heating effect on the rear housing.

[0009] Further in the above description, the heating element includes a heating box, heating pipes and a driving fan. A heating cavity is formed in the heating box. The heat conduction pipe forms a communicating channel with the heating cavity and the heat conduction cavity. The heating pipes are installed in the heating cavity. An air inlet hole is opened on the side of the heating box, and the driving fan is installed on the air inlet hole. The hot air in the heating cavity can flow towards the heat conduction cavity under the drive of the driving fan by the power-on heating of the heating pipes, so as to improve the temperature control efficiency of the heat conduction cavity.

[0010] Further in the above description, a temperature detector is connected to the inner wall of the heating cavity. It can detect the heating temperature, and a temperature detector can be arranged in the heat conduction cavity to detect the temperature in the heat conduction cavity.

[0011] Further in the above description, a clamping part is arranged on the inner wall of the rear housing, and a heat conduction silica gel pad is clamped on the clamping part. The heat conduction silica gel pad is in contact with the inner wall of the rear housing. The clamping part clamps the heat conduction silica gel pad, so that it can transfer heat to the rear housing evenly, thereby improving the heating stability and consistency of the rear housing, enabling the products outside to be heated evenly when passing through the rear housing, and further enhancing the heating efficiency and production quality.

[0012] Further in the above description, the tensioner is composed of a tension cylinder, a tension block and a mounting bracket. A slide rail is provided on the inner side of the mounting bracket. The side of the tension block is paired with the slide rail through a chute. The tension cylinder is installed on the mounting bracket, and the telescopic end of the tension cylinder passes through the mounting bracket and is connected to the tension block. The end of the feeding roller is connected to the tension block, so as to drive the feeding roller to move. By driving the tension block with the tension cylinder, the tension block can move along the slide rail, so that the feeding roller on the tension block can move backward to the rear housing, so that the external product can be roll-pressed when passing between the feeding roller and the rear housing, and the heating stability and uniformity can be improved.

[0013] Further in the above description, a shaft hole is provided inside the feeding roller. The heating roller is coaxially connected to the shaft hole, and sealing caps are connected to both ends of the shaft hole. Through the heating of the heating roller, the heat is transferred to the feeding roller, so that when the feeding roller feeds and rolls the external product, a heating effect is achieved.

[0014] The beneficial effects of the present utility model are as follows: The provided heat conduction cavity is combined with the heating element. When the heating element heats up, the hot air generated can quickly and evenly enter the heat conduction cavity for heat exchange, realizing the efficient heating of the heat conduction cavity, and improving the heating stability and consistency of the rear housing. Thus, the preset temperature can be reached faster, and a stable temperature environment can be maintained, improving the working efficiency of the heat transfer printing machine. The design of the tensioner enables the feeding roller to move relative to the rear housing, so that the printed product can pass through the feeding roller evenly and continuously during the heat transfer process, avoiding printing quality problems caused by material jitter or deviation. In addition, the heat transfer from the heating roller to the feeding roller further enhances the heating effect, ensuring that the surface of the printed product can be in full contact with the surfaces of the feeding roller and the rear housing and be heated when being conveyed, improving the production quality and efficiency of the printed product.
