Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping equipment, in particular to a hot stamping machine with good stability. Background Art

[0002] A hot stamping machine is a specialized printing machine that uses high temperature and high pressure to apply printing materials such as metal sheets, heat transfer films, and hot stamping films to surfaces like paper, plastic, and leather. In my country's printing machinery industry, hot stamping is generally achieved using two methods: flatbed hot stamping and rotary hot stamping. The rotary hot stamping method typically uses a hot stamping roller, a hollow cylinder containing a copper roller that in turn houses a hot oil heating tube.

[0003] The existing hot oil heating hot stamping roller has insufficient fluidity of the hot oil, which causes a certain temperature difference between the oil inlet and the oil outlet, thus affecting the hot stamping quality and resulting in unstable hot stamping quality. At the same time, when the printing film passes through the conveyor belt and passes through the front and back of the hot stamping roller, due to factors such as the vibration of the conveyor belt and unstable movement speed, the flat printing film becomes loose and shifted, and the transmission is not stable, affecting the subsequent hot stamping.

DETAILED DESCRIPTION

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] like Figure 1-6As shown, the utility model provides a hot stamping machine with good stability, including a frame 100, and a printing film conveyor belt 101 and a lifting mechanism 102 arranged on the frame 100. A liftable adjustment platform 200 is installed on the front side of the lifting mechanism 102. A hot stamping film conveying wheel 201 and a hot stamping film rewinding wheel 202 are respectively installed at both ends of the adjustment platform 200. A connecting platform 300 is fixedly installed below the adjusting platform 200. A hot stamping roller 400 is rotatably arranged on the inner side of the connecting platform 300 through a bearing. A hot oil circulation device 500 is installed on the top of the connecting platform 300. An oil guide heating component 600 connected to the hot oil circulation device 500 is installed in the hot stamping roller 400.

[0029] Among them, several stabilizing components 700 for compacting the printing film are installed on the frame 100. Every two stabilizing components 700 form a group and there are two groups in total. The two groups of stabilizing components 700 are respectively located on both sides of the hot stamping roller 400, and each group of stabilizing components 700 is symmetrically arranged in the front and back of the frame 100.

[0030] In this embodiment, each stabilizing component 700 includes a U-shaped seat 701 fixedly set on the frame 100, and an axle pin 702 is fixedly set on the inner side of the U-shaped seat 701. Two rocker arms 703 are rotatably set on the outer side of the axle pin 702. One end of the rocker arm 703 extends out of the U-shaped seat 701 and is rotatably provided with a pressure roller 704. An elastic pressure arm 705 is hingedly installed between the side of the U-shaped seat 701 and the rocker arm 703. Under the action of the elastic pressure arm 705 and the gravity of the pressure roller 704, the pressure roller 704 will contact the printing film on the printing film conveyor belt 101. The pressure roller 704 increases the friction between the printing film and the printing film conveyor belt 101, so that the printing film can be conveyed smoothly.

[0031] In this embodiment, the elastic pressure arm 705 includes a connecting arm 7051 and a movable arm 7052, which are respectively hingedly mounted on the side of the U-shaped seat 701 and the rocker arm 703. The end of the movable arm 7052 away from the rocker arm 703 extends into the connecting arm 7051 and is fixedly connected to a slide plate 7053. The slide plate 7053 is located in the connecting arm 7051 and slides with the connecting arm 7051. A spring 7054 is fixedly arranged between the slide plate 7053 and the connecting arm 7051.

[0032] In this embodiment, the oil-conducting heating assembly 600 includes a heat-conducting heat storage block 601 fixedly connected to the inner wall of the hot stamping roller 400. The inner wall of the heat-conducting heat storage block 601 is installed with annular tubes 602 distributed in a linear array. The two adjacent annular tubes 602 are connected to each other, and the inner circles of the annular tubes 602 at both ends are connected and installed with a number of oil-conducting tubes 603. Sealing blocks 604 are welded between the ends of the several oil-conducting tubes 603. The two ends of the oil-conducting tube 603 are respectively installed with an oil inlet pipe 605 and an oil outlet pipe 606 of the hot oil circulation equipment 500 through the sealing blocks 604 and the sealed bearings. The hot oil is introduced into the oil-conducting tube 603 through the oil inlet pipe 605 and passes into the annular tube 602. After the annular tubes 602 are connected, the hot oil is transferred and discharged through the oil outlet pipe 606 for circulation.

[0033] In this embodiment, a steel ball 607 is provided inside the annular tube 602. The diameter of the steel ball 607 is smaller than the diameter of the annular tube 602, and the diameter of the steel ball 607 is larger than the diameter of the oil guide tube 603. When the hot oil is introduced into the annular tube 602, the steel ball 607 moves in the annular tube 602 and promotes the flow of hot oil under the action of the centrifugal force generated by the rotation of the hot stamping roller 400 and gravity, and the steel ball 607 will not enter the oil guide tube 603 when rolling in the annular tube 602.

[0034] In this embodiment, a number of connecting frames 203 are installed on the adjustment platform 200, and hot stamping film auxiliary wheels 204 are rotatably provided on the connecting frames 203. The hot stamping film auxiliary wheels 204 are respectively located on both sides of the hot stamping roller 400. The number of hot stamping film auxiliary wheels 204 on both sides of the hot stamping roller 400 is at least two, and the height of the hot stamping film auxiliary wheels 204 is higher than the bottom of the hot stamping roller 400. The hot stamping film auxiliary wheels 204 keep the hot stamping film flatly attached to the bottom of the hot stamping tube during the rolling process.

[0035] How to use and working principle of this device:

[0036] When the device is in use, the hot stamping film is installed on the hot stamping film conveying wheel 201, then passes through the hot stamping film conveying wheel 201, the hot stamping roller 400, the hot stamping film conveying wheel 201, and finally is wound up by the hot stamping film winding wheel 202. The printing film moves forward through the printing film conveyor belt 101. During this process, under the action of the elastic pressure arm 705 and the gravity of the pressure roller 704, the pressure roller 704 contacts the printing film on the printing film conveyor belt 101. The pressure roller 704 increases the friction between the printing film and the printing film conveyor belt 101, so that the printing film can be smoothly conveyed, the flat printing film is prevented from loosening and shifting, and the printing film transmission is sufficiently stable.

[0037] During hot stamping, the hot oil circulation device 500 introduces the hot oil into the oil guide pipe 603 through the oil inlet pipe 605. The hot oil enters the annular pipe 602 at the same time through multiple oil guide pipes 603, then passes through the annular pipe 602 in turn and enters the oil outlet pipe 606 through the oil guide pipe 603 on the other side, and returns to the hot oil circulation device 500 through the oil outlet pipe 606 for circulation. When the hot oil is in the annular pipe 602, the heat is transferred to the heat conduction heat storage block 601, and then the heat conduction heat storage block 601 transfers the heat to the hot stamping roller 400. When the hot stamping roller 400 rotates, the steel ball 607 moves in the annular pipe 602 under the action of the centrifugal force generated by the rotation of the hot stamping roller 400 and gravity, and promotes the flow of hot oil, so that the hot oil has high fluidity and transfers more and more uniform heat. At the same time, the heat conduction heat storage block 601 can store a certain amount of heat, so that the temperature will not change sharply, thereby making the temperature of the hot stamping roller 400 more stable, and thus making the hot stamping quality more stable.

[0038] Among them, the working principles of the printing film conveyor belt 101, the lifting mechanism 102, the hot stamping film conveying wheel 201 and the hot stamping film winding wheel 202 are existing technologies. The hot oil circulation equipment 500 includes a comprehensive system of components such as a hot oil pump, a hot oil tank and a heater to realize the heating and circulation of the heat transfer oil. The above are all well known in the art, so they are not elaborated in this application.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
