Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic cup processing technology, and in particular to a rim-rolling device for antibacterial plastic cups. Background Technology
[0002] Currently, plastic cups are generally made by stretching or blow molding. After the plastic cup is formed, it is cut, leaving an outward-extending rim. However, the cut rim is often thin and too sharp, which makes people feel uncomfortable when drinking from plastic cups and can easily scratch their lips.
[0003] However, in the existing technology, most edge-rolling equipment is not convenient to adjust according to the size of the plastic cup. Therefore, different equipment needs to be changed to process plastic cups of different sizes, which increases the cost and reduces the utilization rate of the edge-rolling equipment. Moreover, the mouth of the plastic cup needs to be heated during the edge-rolling process. Traditional heating rods are fixed and not easy to adjust, which reduces the heating effect and affects the edge-rolling effect. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0032] Example 1, such as Figure 1-4 As shown, this utility model provides a edging device for antibacterial plastic cups, including: a processing table 1, with grooves 101 on both sides of the top outer surface of the processing table 1, one groove 101 having a bidirectional screw 102 movably embedded inside, and the other groove 101 having a guide rod 108 fixedly embedded inside; it also includes: multiple movable plates 104, which are movably sleeved on the outer surfaces of the bidirectional screw 102 and the guide rod 108, the multiple movable plates 104 being evenly divided into two groups, and connecting shafts 115 movably embedded on the opposite surfaces of the two groups of movable plates 104; and two edging rollers 105, each fixedly sleeved on... Two drive motors 106 are fixedly installed on the outer surfaces of two connecting shafts 115, and the output ends of the two drive motors 106 pass through the moving plates 104 and are fixedly connected to the connecting shafts 115. An arc-shaped plate 107 is fixedly installed on the upper end of the opposite face of the two moving plates 104, and an inclined telescopic plate 116 is fixedly installed on the lower end of the opposite face of the other two moving plates 104. A servo motor 103 is fixedly installed on one side of the outer surface of the processing table 1, and the output end of the servo motor 103 passes through the slide groove 101 and is fixedly connected to the bidirectional screw 102.
[0033] In this embodiment, the servo motor 103 is turned on to drive the bidirectional screw 102 to rotate. The bidirectional screw 102 can drive the two edge-rolling rollers 105 to move relative to or away from each other through the moving plate 104, which can be adjusted according to the size of the plastic cup. The other two moving plates 104 are movably sleeved on the outer surface of the guide rod 108, which can improve the stability of the edge-rolling rollers 105. At the same time, the two drive motors 106 are turned on to drive the two edge-rolling rollers 105 to rotate in the same direction through the connecting shaft 115, thereby driving the plastic cup to move and edge-roll. The plastic cup to be edge-rolled is guided into the two edge-rolling rollers 105 through the two arc plates 107, so that the edge of the plastic cup is embedded in the thread groove of the edge-rolling roller 105. The heating rod 114 heats the mouth of the plastic cup, which facilitates the edge-rolling rollers 105 to shape it. After the edge-rolling process is completed, the plastic cup is conveyed out through the inclined telescopic plate 116. The inclined telescopic plate 116 can be extended and retracted with the adjustment of the two edge-rolling rollers 105 to better guide the processed plastic cup out.
[0034] Example 2, as Figure 1-4 As shown, two fixing blocks 117 are fixedly installed on both sides of the center of the processing table 1. A round shaft 118 is movably embedded on the opposite surface of the two fixing blocks 117. A transmission roller 119 is fixedly installed on the opposite surface of the two round shafts 118. A U-shaped frame 109 is fixedly installed at the center of the center of the processing table 1. An electric push rod 110 is fixedly installed at the top center of the U-shaped frame 109.

A heating rod 114 is movably embedded inside the U-shaped plate 113. A rectangular groove 111 is opened at the upper end of the opposite surface inside the U-shaped frame 109. A limiting plate 112 is movably embedded inside the two rectangular grooves 111. The two limiting plates 112 are fixedly installed on the outer surface of the U-shaped plate 113.
[0035] In this embodiment, activating the electric push rod 110 can drive the U-shaped plate 113 to move up and down, adjusting according to the size of the plastic cup, so that the heating rod 114 movably embedded inside the U-shaped plate 113 comes into contact with the plastic cup. Limiting plates 112 are fixedly installed at the center of both sides of the U-shaped plate 113. The two limiting plates 112 are movably embedded inside the rectangular groove 111, which can improve the stability of the U-shaped plate 113. A transmission roller 119 is movably installed at the center of the processing table 1. The transmission roller 119 can improve the stability of the plastic cup, allowing it to move better inside the two edge-rolling rollers 105, so that the plastic cup will not fall onto the processing table 1.
[0036] Working principle: In use, the servo motor 103 is turned on to drive the bidirectional screw 102 to rotate. The bidirectional screw 102, through the moving plate 104, can drive the two edge-curling rollers 105 to move relative to or away from each other, adjusted according to the size of the plastic cup. The two moving plates 104 are movably sleeved on the outer surface of the guide rod 108 to improve the stability of the edge-curling rollers 105. Simultaneously, the two drive motors 106 are turned on to drive the two edge-curling rollers 105 to rotate in the same direction through the connecting shaft 115, thereby moving the plastic cup to perform edge-curling. The plastic cup to be edge-curled is guided between the two edge-curling rollers 105 through the two arc-shaped plates 107, so that the edge of the plastic cup is embedded in the threaded groove of the edge-curling roller 105. The heating rod 114 heats the mouth of the plastic cup, facilitating the shaping by the edge-curling rollers 105. After processing, the plastic cup is conveyed out via the inclined telescopic plate 116. The inclined telescopic plate 116 can be extended and retracted with the adjustment of the two edge-rolling rollers 105 to better guide the processed plastic cup out. Activating the electric push rod 110 can drive the U-shaped plate 113 to move up and down. Adjusting according to the size of the plastic cup, the heating rod 114 movably embedded inside the U-shaped plate 113 comes into contact with the plastic cup. Limiting plates 112 are fixedly installed at the center of both sides of the U-shaped plate 113. The two limiting plates 112 are movably embedded inside the rectangular groove 111 to improve the stability of the U-shaped plate 113. A transmission roller 119 is movably installed at the center of the processing table 1. The transmission roller 119 can improve the stability of the plastic cup and make it move better inside the two edge-rolling rollers 105, so that the plastic cup will not fall onto the processing table 1.
