Description

Technical Field

[0001] The utility model relates to the technical field of blister processing, in particular to a uniform heating type blister processing device. Background Art

[0002] Blistering is a plastic processing technology. The main principle is to heat and soften the flat plastic hard sheet, then use vacuum adsorption to the mold surface, and then cool it to form. It is widely used in plastic packaging, lighting, advertising, decoration and other industries.

[0003] According to a uniform heating type blister processing equipment disclosed (Announcement No.: CN208801601U), when blister processing is performed in the above application, after the processed plastic sheet is placed on the mold, the heating element and the fan are started, and the heat generated by the heating element enters the air duct from the air inlet under the action of the wind force generated by the fan. When the wind force generated by the fan acts on the fan blades, the fan blades drive the air duct and the heating plate to rotate synchronously, and the heat is blown out from the heat dissipation holes to act on the plastic sheet to heat the plastic sheet. The heating plate can evenly disperse the heat to the plastic sheet during the rotation process, thereby heating the plastic sheet more evenly and improving work efficiency.

[0004] However, in the above device, the hot air flow must pass through the air duct to be transported to the plastic sheet for heating. In this process, heat is easily lost, which will affect the subsequent heating effect of the material. When the fan blades drive the air guide cover to rotate, when the air guide cover rotates to be out of alignment with the fan outlet, the air guide cover cannot effectively enter the hot air, causing the hot air flow to be transported intermittently, which will reduce work efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a uniform heating type blister processing equipment to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a uniform heat type blister processing equipment, comprising a workbench, a processing box is fixed on the top of the workbench, a mold cavity is opened on the top of the workbench, a fan is fixed on the top of the processing box, a connecting pipe is fixed on the bottom of the fan, a motor is fixed on the top of the processing box, a rotating rod is fixed on the output end of the motor, a processing mechanism and a swing mechanism for disturbing the airflow are arranged in the processing box, and the processing mechanism includes:

[0007] A rotating cylinder, the outer wall of the connecting pipe is rotatably mounted with the rotating cylinder, and an air outlet cover is fixed to the bottom of the rotating cylinder;

[0010] Preferably, the swing mechanism includes a swing plate, which is rotatably mounted on the inner wall of the processing box, and a protrusion is fixed to the bottom of the rotating rod. By setting the swing plate, a turbulence operation can be performed to turbulently operate the hot air flow blown out of the air outlet, so that the hot air flow can be dispersed more evenly, thereby further improving the efficiency of heating the plastic sheet.

[0011] Preferably, a sliding rod passes through the protrusion, and the sliding rod is slidably connected to the penetration point of the protrusion.

[0012] Preferably, a sliding sleeve is fixed to the bottom of the sliding rod, and a fixing rod is fixed to the top groove of the swing plate.

[0013] Preferably, the outer wall of the fixing rod is in contact with the inner wall of the sliding sleeve, and the sliding sleeve moves on the fixing rod, thereby driving the swing plate to swing.

[0014] Compared with the prior art, the utility model provides a uniform heating type blister processing equipment, which has the following beneficial effects:

[0015] 1. The uniform heating type blister processing equipment is provided with a fan, a connecting pipe, a rotating sleeve, an air outlet hood, a heating element and an air outlet. When the workpiece needs to be heated, the air flow can be blown directly onto the workpiece when passing through the heating element, thereby avoiding heat loss caused by the hot air flow being transported in the air duct, and allowing the hot air flow to be transported continuously, avoiding the air guide hood from rotating to be out of alignment with the air outlet of the fan, so that the hot air flow does not enter the air guide hood, affecting the heating efficiency of the plastic sheet.

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a uniform heating type blister processing equipment, including a workbench 1, a processing box 2 is fixed on the top of the workbench 1, a mold cavity 3 is opened on the top of the workbench 1, a fan 4 is fixed on the top of the processing box 2, a connecting pipe 5 is fixed on the bottom of the fan 4, and then the fan 4 can be started to make the air flow blow out from the connecting pipe 5, a motor 6 is fixed on the top of the processing box 2, a rotating rod 7 is fixed on the output end of the motor 6, and when the motor 6 is started, the rotating rod 7 can be rotated, and a processing mechanism 8 and a swing mechanism 9 for disturbing the airflow are arranged in the processing box 2.

[0023] Specifically, the processing mechanism 8 includes a rotating cylinder 81, an air outlet cover 82, a heating element 83, an air outlet hole 84, a driving pulley 85, a transmission belt 87 and a driven pulley 86. The rotating cylinder 81 is rotatably mounted on the outer wall of the connecting tube 5. The air outlet cover 82 is fixed at the bottom of the rotating cylinder 81. When the fan 4 is started, the air flow can pass through the connecting tube 5 into the rotating cylinder 81 and the air outlet cover 82. The inner wall of the air outlet cover 82 is fixed with a heating element 83. When the air flow passes through the heating element 83, the air flow becomes hot. The bottom of the air outlet cover 82 is provided with an air outlet hole 84. The hot air flow can be discharged from the air outlet hole 84. By placing the plastic sheet into the mold cavity 3, the plastic sheet can be softened. A driving pulley 85 is fixed to the outer wall of the movable rod 7, and a driven pulley 86 is fixed to the outer wall of the rotating cylinder 81, and the driving pulley 85 and the driven pulley 86 are connected by a transmission belt 87. When the motor 6 is started, the rotating rod 7 can be rotated to drive the driving pulley 85 to rotate. The driven pulley 86 can be rotated through the transmission belt 87, and the air outlet hood 82 can be driven to rotate through the rotating cylinder 81, so that the hot air flow blown out of the air outlet 84 can be evenly distributed on the plastic sheet, so that uniform heating can be achieved.

[0024] Specifically, the swing mechanism 9 includes a swing plate 91, a fixed rod 95, a protrusion 92, a slide rod 93 and a sliding sleeve 94; the inner wall of the processing box 2 is rotatably mounted with a swing plate 91, a fixed rod 95 is fixed to the top groove of the swing plate 91, a protrusion 92 is fixed to the bottom of the rotating rod 7, a slide rod 93 penetrates the protrusion 92, and the slide rod 93 is slidably connected to the penetration of the protrusion 92, a sliding sleeve 94 is fixed to the bottom of the slide rod 93, and the inner wall of the sliding sleeve 94 is in contact with the outer wall of the fixed rod 95. When the rotating rod 7 rotates, the protrusion 92 can be driven to rotate When the protrusion 92 rotates, the protrusion 92 drives the sliding rod 93 to make a circular motion, and then the sliding rod 93 drives the sliding sleeve 94 to move on the fixed rod 95, so that the sliding sleeve 94 drives the swing plate 91 to swing, and when the sliding rod 93 drives the sliding sleeve 94 to move on the fixed rod 95, the sliding rod 93 slides at the penetration point of the protrusion 92. When the swinging plate 91 swings, the hot air flow blown out of the air outlet 84 can be disturbed, so that the hot air flow can be dispersed more evenly, further improving the efficiency of heating the plastic sheet.

[0025] Working principle: when it is necessary to process the plastic sheet, the plastic sheet can be placed in the mold cavity 3, and then the fan 4 can be started, so that the airflow passes through the connecting pipe 5 into the rotating cylinder 81 and the air outlet hood 82. When the airflow passes through the heating element 83, the airflow becomes hot. An air outlet hole 84 is provided at the bottom of the air outlet hood 82, so that the hot air flow can be discharged from the air outlet hole 84, and the plastic sheet can be softened. When the motor 6 is started, the rotating rod 7 can be rotated to drive the active pulley 85 to rotate, and the driven pulley 86 can be rotated through the transmission belt 87. The air outlet hood 82 can be driven to rotate through the rotating cylinder 81, so that the hot air flow blown out of the air outlet hole 84 can be evenly distributed on the plastic sheet, so that uniform heating can be performed.

[0026] When the rotating rod 7 rotates, the protrusion 92 can be driven to rotate. When the protrusion 92 rotates, the protrusion 92 drives the sliding rod 93 to make a circular motion, and then the sliding rod 93 drives the sliding sleeve 94 to move on the fixed rod 95, and the sliding sleeve 94 drives the swing plate 91 to swing, which can disturb the hot air flow blown out of the air outlet 84, make the hot air flow more evenly dispersed, and further improve the efficiency of heating the plastic sheet.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
