Description

Technical Field

[0001] The utility model specifically relates to the technical field of industrial heating, in particular to a heating device for a voltage flower. Background Art

[0002] As a processing technology capable of creating exquisite patterns on material surfaces, embossing plays a significant role in fields such as packaging and decoration. The importance of a heating device in embossing is self-evident. First and foremost, a suitable heating device ensures that the material reaches the ideal temperature during the embossing process. Only when the material is heated to a specific temperature range can it better withstand the action of the embossing die, resulting in a clear, durable pattern. If the heating device fails to provide stable and uniform heat, the material's temperature will fluctuate, directly affecting the quality of the embossing. For example, too low a temperature may prevent the pattern from appearing clearly, while too high a temperature may deform or even damage the material.

[0003] Early electric heating tubes consisted of three relatively thick infrared heating tubes, each with the same heating element and power, providing overall heating within the embossing roller. However, during production, heat dissipation within the rotating roller cavity caused fluctuations in heat dissipation, resulting in uneven heat transfer within the roller cavity. This could lead to the embossing roller not being able to emboss the pattern if the setting was too small, while the setting being too large could cause localized sticking to the roller, making production uncontrollable and product quality substandard. Utility Model Content

[0004] A heating device for a voltage flower, including an electrical control cabinet, is characterized in that it includes a roller body, a left connecting seat and a right connecting seat are fixedly installed at both ends of the roller body, a full-length heating tube, a left heating tube, a right heating tube, and a middle heating tube are suspended between the left connecting seat and the right connecting seat, and a protective cover is also fixedly installed between the left connecting seat and the right connecting seat, and the protective cover covers the full-length heating tube, the left heating tube, the right heating tube, and the middle heating tube.

[0005] Preferably, the left connecting seat is located at the left end of the roller body, and the right connecting seat is located at the right end of the roller body.

[0006] Preferably, the full-length heating tube is equal to the length of the protective cover.

[0007] Preferably, the lengths of the left heating tube, the right heating tube and the middle heating tube are all one-third of the length of the full-length heating tube.

[0008] Preferably, the positions of the full-length heating tube, the left heating tube, the right heating tube, and the middle heating tube are parallel to each other.

[0009] Preferably, the left heating pipe is close to the left connecting seat, the right heating pipe is close to the right connecting seat, and the middle heating pipe is at the same distance from the left connecting seat and the right connecting seat.

[0010] Preferably, the full-length heating tube, left heating tube, right heating tube and middle heating tube are each provided with a connecting piece at both ends, and the full-length heating tube, left heating tube, right heating tube and middle heating tube are all suspended between the left connecting seat and the right connecting seat through the connecting piece.

[0011] Preferably, the full-length heating tube, the left heating tube, the right heating tube, and the middle heating tube are infrared heating tubes.

[0012] Preferably, the electrical signal of the electrical control cabinet is electrically connected to the full-length heating tube, the left heating tube, the right heating tube, and the middle heating tube, and the electrical control cabinet can complete heating and temperature detection by controlling the full-length heating tube, the left heating tube, the right heating tube, and the middle heating tube.

[0013] The beneficial effects of the present invention are:

[0014] 1. Compared to earlier devices consisting of only three thicker infrared heating tubes, this new device is equipped with a full-length heating tube, a left heating tube, a right heating tube, and a center heating tube. The layout of multiple heating tubes provides more comprehensive coverage of the roller's interior, reducing the problem of uneven heat distribution. For example, different parts of the embossing roller can be provided with corresponding heating tubes to provide heat, making the temperature of the entire roller more uniform. The left and right heating tubes are located near the connecting seats at both ends, which can provide more heat to the roller's ends that are prone to heat dissipation, compensating for the lack of heat at the ends of the roller in earlier devices. The center heating tube is located in the middle and works together with the full-length heating tubes to ensure a stable temperature in the middle of the roller.

[0015] 2. The length of the left, right, and center heating tubes in this utility model is each one-third of the full-length heating tube. This design allows for more precise heating according to the needs of different parts of the roller. For example, in areas where local temperature requirements are less stringent, shorter heating tubes can be used for moderate heating, avoiding the localized overheating that can occur with earlier devices using uniformly powered and length heating tubes.

[0016] 3. This new device features a protective cover fixedly mounted between the left and right connectors, covering the entire length of the left, right, and center heating tubes. The cover protects the heating tubes from collisions and damage during production. It also reduces heat loss, improving heating efficiency. It also prevents operators from accidentally touching the heating tubes, enhancing production safety.

[0017] 4. The electrical control cabinet in this utility model electrically connects the electrical signals to the full-length, left, right, and center heating tubes, enabling individual control of heating and temperature measurement for each heater tube. Compared to earlier devices, where each heater tube had identical power and could not be independently controlled, the new device allows precise temperature adjustment of heater tubes in different locations based on actual production needs. For example, if the temperature of a particular part of the roller is too high or too low, the power of the heater tube in that location can be adjusted independently without affecting the temperatures of other parts. This allows for better temperature control of the embossing roller, improving embossing quality and production stability. BRIEF DESCRIPTION OF THE DRAWINGS
