Description

Technical Field

[0001] This utility model relates to the field of plastic bowl production technology, specifically to a cutting machine for plastic bowl production. Background Technology

[0002] Plastic bowls are a common everyday item, mainly made of plastic, used for holding food. They are affordable, suitable for various occasions, lightweight, easy to clean, and have good heat resistance; some plastic bowls, such as those made of polypropylene (PP), can even be microwaved.

[0003] During the injection molding process of plastic bowls, excess material often forms at the edge of the bowl due to factors such as equipment, mold, and process parameter settings. At this time, it is necessary to manually cut off the excess material at the edge of the bowl and then take it to a grinding machine to process the edge. Traditional equipment has a single function, and the plastic bowl needs to be cut again and then taken to the grinding machine for grinding. This undoubtedly increases the production time and cost. In addition, traditional equipment cannot be adjusted when processing different plastic bowls, and its applicability is also limited. Utility Model Content

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1 As shown, this utility model provides a cutting machine for producing plastic bowls, including a base 1. A motor 2 is fixedly connected to the lower part of the base 1. The output shaft of the motor 2 passes through the base 1 and is fixedly connected to a positioning module 3. The positioning module 3 is rotatably connected to the base 1. Four support columns 8 are fixedly connected to the four corners of the upper part of the base 1. A support plate 6 is fixedly connected above the four support columns 8. A pressing module 7 is fixedly connected to the middle of the support plate 6. A cutting blade 4 is rotatably connected between the base 1 and the support plate 6. The two ends of the cutting blade 4 are threaded and pass through the support plate 6 and the base 1. Two nuts 5 are threadedly connected to both sides of the support plate 6 and the base 1. A grinding device 9 is fixedly connected to the left side of the positioning module 3 on the base 1. When it is necessary to cut the excess material of the plastic bowl, multiple plastic bowls can be stacked on top of the positioning module 3. Then, the wrench 10 is turned to adjust the positioning module 3 to center the plastic bowl. After that, the pressing module 7 presses down to clamp the plastic bowl. The cutting blade 4 is adjusted to a suitable position and then fixed. The plastic bowl above the positioning module 3 is rotated by the motor 2. After the cutting blade 4 cuts off the excess material, the grinding device 9 is adjusted by the wrench 10 to grind the edge of the bowl.

[0024] like Figure 2 As shown, this utility model provides a technical solution: the positioning module 3 includes a limiting block 32, a rotating platform 36, and a bidirectional lead screw 37. Two support seats 33 and pads 35 are fixedly connected to the lower sides of the limiting block 32. The rotating platform 36 is fixedly connected to the lower sides of the support seats 33 and pads 35. Four sliding grooves are provided above the limiting block 32, and a clamping block 31 is slidably connected in each groove. A slide rail 34 is slidably connected to the lower sides of the two front clamping blocks 31, and another slide rail 34 is slidably connected to the lower sides of the two rear clamping blocks 31. Both slide rails 34 are located below the limiting block 32, and a sliding nut 3 is fixedly connected to the lower sides of both slide rails 34. 8. Both sliding nuts 38 have threaded grooves inside. The outer surface of the bidirectional lead screw 37 has threads with different directions at both ends, and each thread is threaded to one of the sliding nuts 38. Both ends of the bidirectional lead screw 37 are rotatably connected to the support base 33. A wrench 10 is engaged at the front end of the bidirectional lead screw 37. When positioning is required, the wrench 10 can be engaged at the front end of the bidirectional lead screw 37 to rotate it. Because of the bidirectional threads on the outside of the bidirectional lead screw 37, the rotation of the bidirectional lead screw 37 will drive the two sliding nuts 38 on the outside to move relative to each other. The two sliding nuts 38 drive the clamping block 31 to slide relative to each other in the groove of the limiting block 32 through the slide rail 34 above them.

[0025] like Figure 3As shown, this utility model provides a technical solution: the sanding device 9 includes two supports 91, with fixed rollers 92 rotatably connected between the two sides of each support 91. Sandpaper 93 is slidably connected to the outer side of the two fixed rollers 92. A fixed seat 94 is fixedly connected to the outer side of the lower fixed roller 92. The lower part of the fixed seat 94 is rotatably connected to the base 1. A connecting rod 96 is rotatably connected to the left side of the fixed seat 94. A sliding nut 95 is rotatably connected to the other end of the connecting rod 96. A lead screw 97 is rotatably connected to the upper part of the base 1. The lead screw 97 is threadedly connected to the sliding nut 95. When it is necessary to adjust the position of the sandpaper 93, the lead screw 97 is rotated by the wrench 10. The lead screw 97 drives the sliding nut 95 to move. The sliding nut 95 pushes the fixed seat 94 to rotate through the connecting rod 96. The sandpaper 93 is fixed on the upper part of the fixed seat 94, thus changing the distance between the surface of the sandpaper 93 and the outer side of the plastic bowl.

[0026] like Figure 4 As shown, this utility model provides a technical solution: a fixing block 99 is slidably connected to the front end of the bracket 91, and two springs 98 are fixedly connected to the bracket 91 behind the fixing block 99. The fixing block 99 is rotatably connected to the fixing roller 92. When the sandpaper 93 needs to be replaced, the outer fixing roller 92 is pushed, and the fixing roller 92 can slide on the bracket 91 through the fixing block 99, so that the sandpaper 93 can be replaced. After the replacement is completed, the fixing roller 92 is released, and the fixing block 99 is pushed by the spring 98 to re-fix the sandpaper 93.

[0027] like Figure 5 As shown, this utility model provides a technical solution: the clamping module 7 includes a fixed plate 72, a second motor 71 is fixedly connected to the upper part of the fixed plate 72, the output shaft of the second motor 71 passes through the fixed plate 72 and is fixedly connected to a second lead screw 73, the other end of the second lead screw 73 is rotatably connected to a second slide rail 75, a slider 74 is threadedly connected to the outer side of the second lead screw 73, the slider 74 is slidably connected to the second slide rail 75, a top rod 76 is fixedly connected to the lower part of the slider 74, and the lower end of the top rod 76 passes through the second slide rail 75 and... The support plate 6 is fixedly connected to the top block 78. The top block 78 is fixedly connected to the guide post 77 on both sides of the top rod 76. The guide post 77 is slidably connected to the motor 2. The turntable 79 is rotatably connected below the top block 78. When it is necessary to press the plastic bowl, the motor 71 drives the slider 74 to slide inside the slide rail 75 through the lead screw 73. The slider 74 pushes the top block 78 through the top rod 76. The turntable 79 below the top block 78 rotates with the plastic bowl to prevent the plastic bowl from causing the top block 78 to rotate and affecting the guide post 77.

[0028] like Figure 6As shown, this utility model provides a technical solution: the front ends of lead screw 97 and bidirectional lead screw 37 are connected to square locking blocks, and the head of the wrench 10 is provided with a square locking groove. The front ends of lead screw 97 and bidirectional lead screw 37 can be locked into the head of the wrench 10, so that the bidirectional lead screw 37 and lead screw 97 can be rotated more conveniently through the wrench 10.

[0029] The working principle of the cutting machine used in the production of this plastic bowl will be explained in detail below.

[0030] like Figure 1-6 As shown, when it is necessary to trim the scrap material from the edge of a plastic bowl, place the plastic bowl above the limiting block 32, and wrench 10 is engaged at the front end of the double-acting screw 37 to rotate the double-acting screw 37. The double-acting screw 37 drives the sliding nut 38 through the double-acting thread on its surface to achieve relative movement. The sliding nut 38 drives the clamping block 31 above through the slide rail 34 to achieve relative forward and backward movement. When the clamping block 31 moves forward and backward, it is limited by the slide groove of the limiting block 32 to achieve relative left and right movement. The slide groove inside the slide rail 34 is used to avoid obstruction. At this point, the four clamping blocks 31 above the limiting block 32 can be tightened inward. While the clamping blocks 31 are tightening inward, they will center the upper part, making it the exact center of the limiting block 32. Then, motor 71 will push slider 74 through screw 73. Slider 74 pushes top block 78 and turntable 79 down through top rod 76. Turntable 79 presses the plastic bowl tightly against the limiting block 32. Above the position block 32, adjust the position of the cutting blade 4 so that it can cut the excess material on the edge of the plastic bowl. The motor 2 drives the positioning module 3 to rotate, and at the same time, it drives the plastic bowl on the positioning module 3 to rotate. The turntable 79 rotates with the plastic bowl to complete the cutting. Before sanding the edge of the plastic bowl, the position of the sanding device 9 needs to be adjusted. The wrench 10 is locked to the front end of the lead screw 97. The lead screw 97 is rotated to drive the sliding nut 95 to move. The sliding nut 95 drives the fixed seat 94 to rotate through the connecting rod 96. The fixed seat 94 drives the sandpaper 93 above to rotate to change the distance between the sandpaper 93 and the plastic bowl. When the sandpaper 93 needs to be replaced, push the outer fixed roller 92. The fixed roller 92 can slide the bracket 91 on the bracket 91 through the fixed block 99. At this time, the sandpaper 93 can be replaced. After replacement, release the fixed roller 92 and push the fixed block 99 through the spring 98 to fix the sandpaper 93 again.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
