Description

Technical Field

[0001] The present invention belongs to the technical field of plastic bottle production, and more specifically, relates to a blow molding bottle mouth cutting mechanism and a cutting method for producing and processing plastic bottles. Background Art

[0002] Plastic bottles are primarily made from materials such as polyethylene or polypropylene, with various organic solvents added. Plastic bottles are widely made from polyester (PET), polyethylene (PE), and polypropylene (PP). After adding the appropriate organic solvents, they are heated to high temperatures and then blow-molded, extruded, or injection-molded through plastic molds. They are primarily used as disposable plastic packaging for liquids or solids such as beverages, food, pickles, honey, dried fruits, cooking oil, and pesticides. Plastic bottles are characterized by their unbreakable nature, low cost, high transparency, and food-grade raw materials.

[0003] Plastic bottles are often formed by blow molding through molds. After the plastic bottles are successfully blown, the bottle mouth often has defects. At this time, the defective bottle mouth needs to be cut. The traditional cutting method is for the worker to hold the bottle and cut the bottle mouth.

[0022] S8. Take out the rinsed bottles in the sink and sort and collect them.

[0023] S8. Then take out the rinsed bottles in the sink and sort and collect them.

[0024] One of the above technical solutions of the present invention has at least one of the following advantages or beneficial effects:

[0025] 1. By setting a limit structure, first place the bottle inside the long column, then push the first slide bar, the first slide bar will move towards the direction of the second slide bar, at this time the fixed block on the surface of the first slide bar will pull the fixed block on the surface of the second slide bar to move through the connecting rope, at this time the second slide bar will move towards the first slide bar, at this time the connecting rope will make the first slide bar and the second slide bar move towards each other at the same time through the rotating shaft, at the same time the round rods on the surface of the first slide bar and the second slide bar will drive the clamping block to clamp the bottle mouth, at the same time the worker presses the first slide bar with his hand, and then slides the rectangular frame, due to the workbench There is a slide groove on the surface, and the rectangular frame will slide on the surface of the workbench through the slide groove. When the rectangular frame drives the saw blade close to the bottle, the height of the saw blade is adjusted by adjusting the slide plate, and then the motor is started to enable the saw blade to cut the bottle mouth. The insert block plays a role in limiting the sliding of the slide plate. Since the bottle mouth is relatively hard, it will be difficult to deviate after being limited. The whole structure solves the problem that the traditional cutting method is that the worker holds the bottle to cut the bottle mouth, but since the bottle body of the plastic bottle is relatively soft, the worker often causes the bottle mouth to deviate when cutting, affecting the use of the bottle.

[0026] 2. By setting up a collection structure, when the bottle is cut, the bottle is taken out from the inside of the long column and placed in the water tank. Since the water tank is filled with water, the debris generated by cutting on the surface of the bottle will be washed away by the water. Then the disc is moved to the top of the water tank, and then the connecting rod at the bottom of the disc is moved so that the connecting rod is close to the round rod, and the arc block on the connecting rod is stuck on the surface of the round rod. Then the round rod and the frame can be pulled up by the disc, connecting rod and arc block. When it rises to a certain height, by rotating the square on the surface of the round rod, the square will be inserted into the groove to limit the height of the frame. At this time, the filter screen on the surface of the frame will drive the bottle on its surface to rise in the water tank, avoiding the situation where the bottle at the bottom is difficult to be taken out due to the water tank being too deep when taking out the cleaned bottle. The rectangular block limits the lowest position of the frame in the water tank.

[0027] 3. By setting up an auxiliary structure, when it is necessary to take out the bottle in the long column, first rotate the long column. At this time, the long column will tilt toward the direction of the sink. Then insert the column into the limit plate and the long column to limit the rotation of the long column. Since a limit hole is provided on the surface of the long rod, the size of the limit hole is adapted to the size of the limit block. At this time, insert the round bar into the long rod and then rotate the round bar. The round bar will drive the limit block to rotate. At this time, the limit block will be staggered with the limit hole on the surface of the long rod. At this time, pull the handle, and the handle will pull the long rod up through the round bar. When the long rod rises, it will drive all the bottles in the long column to rise. When the bottle is removed from the long column, it will fall into the sink. The round block leaves a gap between the long rod and the long column, thereby facilitating the insertion of the rectangular block. The entire structure solves the problem of needing to take out the bottles one by one when removing them from the long column. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0044] Example 1, as Figure 1-9 As shown, the present invention provides a blow molding bottle mouth cutting mechanism and cutting method for plastic bottle production and processing, including a workbench 1 and a limiting structure 4. The surface of the workbench 1 is rotatably connected to a long column 2, a bottle 3 is placed inside the long column 2, and a limiting structure 4 is provided on the surface of the long column 2.

[0045] The following steps are involved:

[0046] S1, after the bottles 3 are produced, they are collected and sorted together and moved to the vicinity of the workbench 1;

[0047] S2. The staff inserts the bottle 3 into the interior of the long column 2 until the bottom end of the bottle 3 touches the long rod 51;

[0048] S3, then move the first slide bar 402 and the second slide bar 414 toward each other, at which time the clamping block 404 clamps the bottle mouth of the bottle 3 and exposes a portion of the bottle mouth;

[0049] S4, then press the first slide bar 402 by hand and move the rectangular frame 409, at this time the rectangular frame 409 will drive the motor 412 and the saw blade 7 to approach the bottle 3;

[0050] S5, then adjusting the height of the slide plate 410 so that the saw blade 7 can cut the bottle mouth;

[0051] S6, after the bottle mouth is cut off, the long column 2 is rotated to cut the long column 2 obliquely, and then the long rod 51 is pulled by the handle 54, and the long rod 51 removes all the bottles 3, so that the bottles 3 fall into the water tank 69;

[0052] S7, then pour clean water into the water tank 69 to rinse the debris left on the bottle 3 due to cutting;

[0053] S8. Then, the bottles 3 rinsed clean in the water tank 69 are taken out for sorting and collection.

[0054] The specific settings and functions of the limiting structure 4, the collecting structure 6 and the auxiliary structure 5 are described in detail below.

[0055] like Figure 1 and Figure 3As shown, the limiting structure 4 includes a fixed frame 401, the surface of the fixed frame 401 is fixedly connected to the long column 2, the surface of the fixed frame 401 is slidably connected to the first slide bar 402 and the second slide bar 414, the surfaces of the first slide bar 402 and the second slide bar 414 are fixedly connected to the round rod 403, the surface of the round rod 403 is fixedly connected to the clamping block 404, the surface of the workbench 1 is slidably connected to the rectangular frame 409, the interior of the rectangular frame 409 is slidably inserted with a slide 410, the surface of the slide 410 is fixedly connected to the round frame 411, the inner wall of the round frame 411 is fixedly connected to the motor 412, and the output of the motor 412 The output end is fixedly connected to the saw blade 7, the inner sliding insertion block 413 of the rectangular frame 409 is provided, and the surface of the slide plate 410 is provided with a rectangular groove. First, the bottle 3 is placed inside the long column 2, and then the first slide bar 402 is pushed. The first slide bar 402 will move toward the direction of the second slide bar 414. At this time, the fixed block 405 on the surface of the first slide bar 402 will pull the fixed block 405 on the surface of the second slide bar 414 to move through the connecting rope 408. At this time, the second slide bar 414 will move toward the first slide bar 402. At this time, the connecting rope 408 will make the first slide bar 402 and the second slide bar 414 move simultaneously through the rotating shaft 407. The two bottles 3 are moved in a direction close to each other. At the same time, the round rod 403 on the surface of the first slide bar 402 and the second slide bar 414 will drive the clamping block 404 to clamp the bottle mouth of the bottle 3. At the same time, the worker presses the first slide bar 402 with his hand. The surfaces of the first slide bar 402 and the second slide bar 414 are fixedly connected with the fixing block 405. The surfaces of the two fixing blocks 405 are fixedly connected with the connecting rope 408. The surface of the fixing frame 401 is fixedly connected with the connecting plate 406. The surface of the connecting plate 406 is rotatably connected with the rotating shaft 407. The size of the inserting block 413 is adapted to the size of the rectangular groove. The rectangular groove is used to insert the block 413. Insert, the shape of the connecting plate 406 is the letter "L", the connecting rope 408 and the rotating shaft 407 are movably connected, and then the rectangular frame 409 is slid. Since a slide groove is provided on the surface of the workbench 1, the rectangular frame 409 will slide on the surface of the workbench 1 through the slide groove. When the rectangular frame 409 drives the saw blade 7 to approach the bottle 3, the height of the saw blade 7 is adjusted by adjusting the slide plate 410, and then the motor 412 is started, so that the saw blade 7 can cut the bottle mouth, wherein the insert block 413 plays a role in limiting the sliding of the slide plate 410. Since the bottle mouth of the bottle 3 is relatively hard, it will be difficult to deviate after being limited.

[0056] The effect achieved by the entire limiting structure 4 is that, by setting the limiting structure 4, the bottle 3 is first placed inside the long column 2, and then the first slide bar 402 is pushed, and the first slide bar 402 will move toward the direction of the second slide bar 414. At this time, the fixed block 405 on the surface of the first slide bar 402 will pull the fixed block 405 on the surface of the second slide bar 414 to move through the connecting rope 408. At this time, the second slide bar 414 will move toward the first slide bar 402. At this time, the connecting rope 408 will make the first slide bar 402 and the second slide bar 414 move toward each other at the same time through the rotating shaft 407. At the same time, the round rods 403 on the surfaces of the first slide bar 402 and the second slide bar 414 will drive the clamping block 404 to clamp the bottle mouth of the bottle 3, and the worker will press the bottle mouth with his hand. The first slide bar 402 is then slid, and the rectangular frame 409 is slid. Since a slide groove is provided on the surface of the workbench 1, the rectangular frame 409 will slide on the surface of the workbench 1 through the slide groove. When the rectangular frame 409 drives the saw blade 7 close to the bottle 3, the height of the saw blade 7 is adjusted by adjusting the slide plate 410, and then the motor 412 is started, so that the saw blade 7 can cut the bottle mouth. The insert block 413 serves to limit the sliding of the slide plate 410. Since the bottle mouth of the bottle 3 is relatively hard, it will be difficult to deviate after being limited. The whole structure solves the problem that the traditional cutting method is that the worker holds the bottle 3 to cut the bottle mouth, but since the bottle body of the plastic bottle is relatively soft, the worker often causes the bottle mouth to deviate when cutting, affecting the use of the bottle 3.

[0057] like Figure 1 and Figure 7 As shown, the surface of the workbench 1 is provided with a collecting structure 6, which includes a water trough 69. The water trough 69 is opened on the surface of the workbench 1. The inner wall of the water trough 69 is slidably connected to a frame 63. The surface of the frame 63 is fixedly connected to a round rod 64. The top of the round rod 64 is rotatably connected to a block 65. The inner wall of the water trough 69 is fixedly connected to a rectangular block 66. The inner wall of the water trough 69 is provided with a groove 68. The surface of the frame 63 is fixedly connected to a filter screen. When the bottle 3 is cut, the bottle 3 is taken out from the inside of the long column 2 and placed in the water trough 69. Since the water trough 69 is filled with water, the debris generated on the surface of the bottle 3 due to cutting will be washed away by the water. Then the disc 61 is moved above the water trough 69. Then move the connecting rod 62 at the bottom end of the disc 61 so that the connecting rod 62 is close to the round rod 64, and the arc block 67 on the connecting rod 62 is stuck on the surface of the round rod 64. Then the round rod 64 and the frame 63 can be pulled up by the disc 61, the connecting rod 62, and the arc block 67. When it rises to a certain height, by rotating the block 65 on the surface of the round rod 64, the block 65 will be inserted into the groove 68 to limit the height of the frame 63. The size of the groove 68 is adapted to the size of the block 65. The groove 68 is used to insert the block 65. The surface of the round rod 64 is movably connected to the arc block 67, the surface of the arc block 67 is fixedly connected to the connecting rod 62, and the surface of the connecting rod 62 is slidably connected to the disc 61.

[0058] The effect achieved by the entire collecting structure 6 is that, by setting up the collecting structure 6, after the bottle 3 is cut, the bottle 3 is taken out from the inside of the long column 2 and placed in the water tank 69. Since the water tank 69 is filled with water, the debris generated by cutting on the surface of the bottle 3 will be washed away by the water. Then, the disc 61 is moved to the top of the water tank 69, and then the connecting rod 62 at the bottom of the disc 61 is moved so that the connecting rod 62 is close to the round rod 64, and the arc block 67 on the connecting rod 62 is stuck on the surface of the round rod 64. Then, the disc 61 and the connecting rod 62 can be used to collect the bottles 3. The connecting rod 62 and the arc block 67 pull the round rod 64 and the frame 63 to rise. When they rise to a certain height, by rotating the square block 65 on the surface of the round rod 64, the square block 65 will be inserted into the groove 68 to limit the height of the frame 63. At this time, the filter screen on the surface of the frame 63 will drive the bottles 3 on its surface to rise in the water tank 69, avoiding the situation where the bottles 3 at the bottom are difficult to take out after being washed due to the water tank 69 being too deep. The rectangular block 66 limits the lowest position of the frame 63 in the water tank 69.

[0059] Example 2, based on Example 1, Figure 1 and Figure 5 As shown, the interior of the long column 2 is provided with an auxiliary structure 5, which includes a long rod 51, the surface of the long rod 51 is slidably connected to the long column 2, the bottom end of the long rod 51 is fixedly connected to a round block 52, the interior of the long rod 51 is movably inserted with a round bar 53, the top of the round bar 53 is fixedly connected to a handle 54, the surface of the round bar 53 is fixedly connected to a limiting block 55, the position of the workbench 1 relative to the long column 2 is fixedly connected to a limiting plate 56, the surface of the limiting plate 56 is provided with a socket 58, and the inside of the socket 58 is inserted with a plug 57. When it is necessary to take out the bottle 3 in the long column 2, the long column 2 is rotated first, and the long column 2 will tilt toward the direction of the water tank 69, and then the plug 57 is inserted into the limiting plate 56 and the long column 2 The rotation of the long column 2 is limited. A connecting groove is provided on the side wall of the long column 2. The size of the connecting groove is adapted to the size of the plug post 57. The connecting groove is used to insert the plug post 57. Since a limiting hole is provided on the surface of the long rod 51, the size of the limiting hole is adapted to the size of the limiting block 55. At this time, the round bar 53 is inserted into the long rod 51, and then the round bar 53 is rotated. The round bar 53 will drive the limiting block 55 to rotate. At this time, the limiting block 55 will be staggered with the limiting hole on the surface of the long rod 51. At this time, pull the handle 54, and the handle 54 will pull the long rod 51 up through the round bar 53. When the long rod 51 rises, it will drive all the bottles 3 in the long column 2 to rise. When the bottle 3 is removed from the long column 2, it will fall into the water tank 69.

[0060] The effect achieved by the entire auxiliary structure 5 is that, by setting the auxiliary structure 5, when it is necessary to take out the bottle 3 in the long column 2, the long column 2 is rotated first. At this time, the long column 2 will tilt toward the water tank 69, and then the plug post 57 is inserted into the limit plate 56 and the long column 2 to limit the rotation of the long column 2. Since a limit hole is provided on the surface of the long rod 51, the size of the limit hole is adapted to the size of the limit block 55. At this time, the round bar 53 is inserted into the long rod 51, and then the round bar 53 is rotated. The round bar 53 will drive the limit block 55 to rotate. At this time, the limit block 55 will be staggered with the limit hole on the surface of the long rod 51. At this time, the handle 54 is pulled, and the handle 54 will pull the long rod 51 up through the round bar 53. When the long rod 51 rises, all the bottles 3 in the long column 2 will be driven to rise. When the bottle 3 is removed from the long column 2, it will fall into the water tank 69. The entire structure solves the problem of needing to take out the bottles 3 one by one when removing them from the long column 2.
