Description

Technical Field

[0001] The invention relates to the technical field of hot stamping equipment, in particular to a flower roller heating mechanism of a hot melt adhesive hot stamping machine. Background Art

[0002] The hot stamping process on clothing with hot stamping machines is mainly electrochemical aluminum hot stamping foil, which mainly uses heating and pressurization to transfer patterns or texts to the surface of the hot stamped material. The old hot stamping process uses oily hot stamping paste, which accumulates under the flower roller. The hot stamping paste is heated to drive the flower roller to rotate, and the hot stamping paste adheres to the surface of the flower roller. The flower roller is heated by the hot stamping paste.

[0003] The traditional method is prone to produce waste gas, affecting the surrounding working environment and harming the health of workers. Therefore, hot melt adhesive is used instead of traditional oil-based hot stamping paste. However, the traditional flower roller heating effect is not good. It is achieved by attaching high-temperature objects on the surface, and the heat is more likely to be lost. The early heating is likely to cause uneven temperature of the flower roller, affecting the initial hot stamping effect. Summary of the invention

DETAILED DESCRIPTION

[0028] The embodiment of the present invention provides a flower roller heating mechanism for a hot melt adhesive hot stamping machine, such as Figure 1-6 As shown, it is placed on the frame 1, including a flower roller 2, the end of the flower roller 2 is pivotally connected to the frame 1, the inside of the flower roller 2 is hollow, a hot steam conveyor 8 is placed on one side of the frame 1, the working end of the hot steam conveyor 8 is connected to the end of the flower roller 2, and a plurality of detection components 5 are arranged in the flower roller 2, and the detection components 5 are used to sense whether the temperature of each area inside the flower roller 2 is consistent. The flower roller 2 is made of heat-conducting material.

[0029] The detection component 5 is suspended in the flower roller 2. The detection component 5 includes a base 51, a temperature conducting tube 52, a magnetic ring 53, a magnetic block 54 and an elastic rope 55. The temperature conducting tube 52 is fixedly installed on the base 51 at an equal distance. The temperature conducting tube 52 is arranged vertically. The magnetic ring 53 is slidably fitted outside the temperature conducting tube 52, and the magnetic block 54 is slidably fitted inside the temperature conducting tube 52. A spring 56 is fixedly installed at the bottom of the magnetic block 54, and the elastic rope 55 is fixedly tied between two adjacent magnetic rings 53.

[0030] Carbonated water is poured into the temperature conducting tube 52 and above the magnetic block 54 . Rubber rings are fixedly wrapped around the upper and lower ends of the magnetic block 54 . The rubber rings are in contact with the inner wall of the temperature conducting tube 52 . The magnetic block 54 and the rubber ring cooperate to act as a piston in the temperature conducting tube 52 . The magnetic ring 53 is attracted by the magnetic force of the magnetic block 54 .

[0031] Whether the temperature at various locations inside the pattern roller 2 is the same can be determined by checking whether the magnetic rings 53 on each detection assembly 5 are on the same horizontal line.

[0032] A tension sensor 531 is fixedly installed at the connection between the magnetic ring 53 and the elastic rope 55. When two adjacent magnetic rings 53 are at the same horizontal line, the elastic rope 55 is just in a tightened state. The lower end of the spring 56 is welded to the bottom of the inner wall of the temperature conducting tube 52. A single-chip microcomputer 511 and a battery are fixedly installed in the base 51. The single-chip microcomputer 511, the battery, and the tension sensor 531 are electrically connected. The single-chip microcomputer 511 feeds back information to the outside world through wireless transmission technology. Since this is a conventional technical means, it will not be described in detail.

[0033] Combined with Figure 5 The interior of the temperature conducting tube 52 and below the magnetic block 52 is in a vacuum state, and the entire magnetic block 52 is supported by a spring 56 .

[0034] Working principle: hot steam is sent into the hollow flower roller 2. As the hot steam accumulates, the temperature inside the flower roller 2 begins to rise, and the heat is transferred to the temperature conducting tube 52. Carbonated water generates carbon dioxide gas and water when it encounters heat. The carbon dioxide gas accumulates on the top of the inner wall of the temperature conducting tube 52. As the gas continues to increase, it pushes the magnetic block 54 down, and the magnetic block 54 moves down, driving the magnetic ring 53 down. Due to the different temperatures in different areas, the degree of descent of the magnetic ring 53 on the temperature conducting tube 52 corresponding to the area also varies.

[0035] When there is a height difference between adjacent magnetic rings 53, the elastic rope 55 is pulled by the magnetic rings 53 at both ends, and the value measured by the tension sensor 531 changes, and transmits the information to the single-chip microcomputer 511, which feeds back the information to the outside world. When the information fed back in the flower roller 2 remains consistent, it means that the flower roller 2 has been preheated and subsequent hot stamping measures can be carried out. The above-mentioned carbonated water needs to be replaced regularly. After the flower stick 2 stops working, just disassemble the flower roller 2 and replace the temperature guide tube 52 inside.

[0036] There are two extended edges 521 on the surface of the heat conducting tube 52 , and the heat conducting tube 52 and the extended edges 521 are integrally formed. The two extended edges 521 are arranged up and down, and the magnetic ring 53 is located between the two extended edges 521 .

[0037] The pattern roller 2 includes an iron tube 21 and two semi-cylinders 22. The two semi-cylinders 22 are assembled into a cylinder. The outer surface of the iron tube 21 is engraved with patterns. The iron tube 21 is sleeved outside the cylinder. The semi-cylinder 22 is provided with a plurality of heating chambers 221. The detection component 5 is placed in the heating chamber 221. Two adjacent heating chambers 221 are connected to each other.

[0038] A cross bar 3 is provided inside the flower roller 2. The cross bar 3 is located at the central axis of the flower roller 2. There is a fork at the end of the cross bar 3. The forked end is fixedly installed on the inner wall of the flower roller 2. A counterweight bar 4 is pivotally connected to the cross bar 3. The counterweight bar 4 is used to connect with the detection component 5.

[0039] A vertical main connecting rod 41 is fixedly installed at the middle section of the counterweight bar 4, and a vertical secondary connecting rod 42 is fixedly installed at the end of the counterweight bar 4. The main connecting rod 41 and the secondary connecting rod 42 are pivotally connected to the crossbar 3, and the top of the main connecting rod 41 is welded to the base 51. The counterweight bar 4 is used to ensure that the temperature conducting tube 52 is always vertically upward during the rotation of the flower roller 2.

[0040] The upper and lower ends of the semi-cylinder 22 are symmetrically welded with protrusions 222, and the protrusions 222 are provided with screw holes. After the two semi-cylinders 22 are close to each other and fit together, screws are passed through the screw holes to achieve the purpose of fixed assembly. The ends of the semi-cylinders 22 are pivotally connected with a paddle 223 that can rotate 180°. The iron tube 21 is sleeved outside the cylinder, and the paddle 223 is rotated 180°. The paddle 223 clamps the iron tube 21 to fix the iron tube 21.

[0041] The end of the flower roller 2 passes through the frame 1 and is sleeved with a gear ring 6, the inner side of the gear ring 6 is provided with an internal thread, and the outer surface of the end of the semi-cylinder 22 is provided with an external thread. The gear ring 6 is fixedly installed on the end of the flower roller 2 through the cooperation of the internal and external threads.

[0042] The frame 1 is equipped with a driving gear 11 driven by a motor, which meshes with the gear ring 6. The working end of the hot steam conveyor 8 is connected with a valve 7, and the pattern roller 2 and the hot steam conveyor 8 are connected together through the valve 7. The hot steam is sent into the pattern roller 2, and the driving gear 11 drives the pattern roller 2 to rotate slowly, while the valve 7 is closed, so that the hot steam stays in the pattern roller 2, which plays a role in preheating the pattern roller 2.

[0043] In summary, the flower roller heating mechanism of the hot melt adhesive hot stamping machine is composed of an iron tube 21 and a semi-cylinder 22 to form a flower roller 2. The semi-cylinder 22 is provided with a heating chamber 221. By sending hot steam into the heating chamber 221, the traditional heating method is replaced to reduce heat loss, speed up the heating speed of the flower roller 2, and improve energy utilization. Temperature conducting pipes 52 are arranged at various places inside the flower roller 2. The temperature conducting pipes 52 are slidably matched with magnetic rings 53 and magnetic blocks 54. Carbonated water is filled in the temperature conducting pipes 52. Carbonated water generates carbon dioxide when heated. The carbon dioxide pushes the magnetic block 53 to move. The magnetic block 54 drives the magnetic ring 53 to move. According to whether the magnetic rings 53 in each area are on the same horizontal line, it is judged whether the temperature inside the entire flower roller 2 is consistent. In this way, the uneven temperature of the flower roller 2 in the initial heating stage is avoided to affect the hot stamping effect.
