Description

Technical Field

[0001] This utility model relates to the field of plastic container manufacturing and processing technology, and in particular to a clamping device for spraying plastic bottle surface. Background Technology

[0002] Plastic bottles are plastic containers made from materials such as polyethylene or polypropylene with the addition of various organic solvents. They are characterized by being unbreakable, inexpensive, and highly transparent. They are widely used not only for packaging carbonated beverages, drinking water, fruit juice, enzymes, and tea drinks, but also for packaging food, chemicals, pharmaceuticals, and many other fields. During the production of plastic bottles, their surfaces need to be sprayed with color.

[0003] When spraying and coloring the surface of plastic bottles, a clamping device is needed to fix them. Existing clamping devices generally fix the outside of the plastic bottle. The plastic bottle will not only be dented inward due to the pressure of the clamping device, making it difficult to fix properly, but the surface of the plastic bottle cannot be fully sprayed due to the obstruction of the clamping device, requiring a second spraying. This is cumbersome to use and not conducive to the spraying work. Summary of the Invention

[0004] In view of this, the present invention provides a clamping device for spraying coating on the surface of plastic bottles. The main technical problem to be solved is that the pressure of the clamping device can easily cause the plastic bottle to be dented and prevent the surface of the plastic bottle from being fully sprayed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a clamping device for spraying coating on the surface of a plastic bottle, comprising a base box, a slide rail fixedly connected to the outer side of the base box, a lifting frame movably connected inside the slide rail, a spraying device fixedly connected to the upper part of the lifting frame, a fixed seat fixedly connected to the top of the base box, a fixing device fixedly connected to the top of the fixed seat, the fixing device comprising a fixed shell fixedly connected to the top of the fixed seat, a connecting shaft movably connected inside the fixed shell, a second driven gear fixedly connected to the upper part of the outer side of the connecting shaft, a first driven gear fixedly connected to the lower part of the outer side of the connecting shaft, a top column movably connected to the upper part of the inner side of the fixed shell, the top column meshing with the second driven gear, a driving gear meshing between the first driven gear, and a placement sleeve installed on the surface of the fixed seat.

[0006] By adopting the above technical solution, the rotation of the driving gear can drive the four first driven gears to rotate, thereby causing the four connecting shafts to rotate, and causing the second driven gears to rotate.

[0007] As a further description of the above technical solution: the top column includes a column body movably connected to the upper part of the fixed shell, the outer end of the column body is fixedly connected to a top block, and the side of the column body near the second driven gear is fixedly connected to a fixed tooth.

[0008] By adopting the above technical solution, the forward and reverse rotation of the second driven gear allows the column to move back and forth inside the fixed shell. When the bottle mouth of the plastic bottle is inserted into the outside of the fixing device, the column moves outward, allowing the top block to press against the inner wall of the plastic bottle mouth, thereby fixing the plastic bottle. Since the bottle mouth of the plastic bottle is relatively hard, it will not deform due to compression, and it will not block the outside of the plastic bottle, ensuring that the outside of the plastic bottle can be fully sprayed.

[0009] As a further description of the above technical solution: the bottom box includes a box body, a support column is fixedly connected to the lower part of the box body, a toothed sleeve is movably connected to the outer side of the box body, a connecting block is fixedly connected to the outer side of the toothed sleeve, a rotating motor is fixedly connected to the inside of the box body, a rotating shaft is fixedly connected to the output end of the rotating motor, a rotating gear is fixedly connected to the top of the rotating shaft, and the rotating gear meshes with the toothed sleeve.

[0010] By adopting the above technical solution, the rotating motor is started, which enables the rotating shaft to drive the rotating gear to rotate. The rotation of the rotating gear drives the gear sleeve to rotate, which in turn drives the slide rail and the lifting frame to rotate, so that the spraying device can rotate, which facilitates the spraying of the outer circumference of the plastic bottle.

[0011] As a further description of the above technical solution: the fixed base includes a base body fixedly connected to the top of the housing, a drive motor fixedly connected inside the base body, a drive shaft fixedly connected to the output end of the drive motor, the drive shaft fixedly connected to the drive gear, a sliding column fixedly connected to the inner side of the fixed housing, and a spring movably sleeved on the outer side of the sliding column.

[0012] By adopting the above technical solution, the drive shaft can be driven to rotate by starting the drive motor. The diameter of the base and the fixed shell is matched with the inner diameter of the bottle mouth of the plastic bottle, so that the plastic bottle can be inserted into the outside of the base and the fixed shell.

[0013] As a further description of the above technical solution: the slide rail includes a rail body fixedly connected to the rear side of the connecting block, a battery fixedly connected to the left side of the rail body, a lifting motor fixedly connected to the lower part of the rail body, and a stud fixedly connected to the output end of the lifting motor.

[0014] By adopting the above technical solution, the stud can be rotated by starting the lifting motor, and the lifting block can be raised and lowered by rotating forward and backward, thereby adjusting the height of the spraying device to facilitate spraying the outer circumference of the plastic bottle.

[0015] As a further description of the above technical solution: the lifting frame includes a lifting block threaded to the outside of the stud, the rear side of the lifting block is fixedly connected to the frame body, and the upper part of the frame body is provided with a fixing groove.

[0016] By adopting the above technical solution, the fixing groove is used to fix the spraying device.

[0017] As a further description of the above technical solution: the spraying device includes a paint tank fixedly connected to the upper part of the frame, a feed pipe fixedly connected to the top of the paint tank, a spray pipe fixedly connected to the lower part of the paint tank, a spraying pump installed on the outside of the spray pipe, and a nozzle fixedly connected to the lower end of the feed pipe.

[0018] By adopting the above technical solution, the paint in the paint tank can be sprayed from the nozzle to the plastic bottle through the spray pipe by starting the spray pump. Under the drive of the lifting motor and the rotating motor, it can rotate and lift, thereby enabling it to spray various parts of the outside of the plastic bottle.

[0019] As a further description of the above technical solution: the placement sleeve includes a slider movably connected to the outside of the sliding column, the outer end of the slider is fixedly connected to the sleeve body, and the lower part of the slider is fixedly connected to the spring.

[0020] By adopting the above technical solution, after the spraying is completed, the control fixing device removes the fixing of the plastic bottle, and the placement sleeve can move upward under the action of the spring, thereby pushing the plastic bottle upward and making it easy to remove the plastic bottle.

[0021] By employing the above technical solution, the clamping device for spraying plastic bottle surface according to this utility model has at least the following beneficial effects: Compared with existing technologies, this clamping device for spraying plastic bottles facilitates the fixation of plastic bottles by providing a fixed base and a fixing device. In use, the bottle opening is inserted into the outside of the base and the fixing shell. As it moves downwards, it pushes the placement sleeve downwards, compressing the spring. When the sleeve reaches its lowest point, the drive motor is activated, causing the drive shaft to rotate the drive gear. The rotation of the drive gear, in turn, drives four first driven gears, which in turn rotate four connecting shafts, causing the second driven gears to rotate. The forward and reverse rotation of the second driven gears allows the column to move back and forth inside the fixing shell, allowing the top block to press against the inner wall of the plastic bottle opening, thus fixing the plastic bottle. Because the bottle opening is relatively rigid, it will not deform due to compression and will not obstruct the outer side of the plastic bottle, ensuring that the outer side of the plastic bottle can be fully sprayed.

[0024] Reference Figure 1-5 This utility model provides a clamping device for spraying plastic bottles, including a base box 1. A slide rail 4 is fixedly connected to the outside of the base box 1. A lifting frame 5 is movably connected inside the slide rail 4. A spraying device 6 is fixedly connected to the upper part of the lifting frame 5. A fixing seat 2 is fixedly connected to the top of the base box 1. A fixing device 3 is fixedly connected to the top of the fixing seat 2. The fixing device 3 includes a fixing shell 301 fixedly connected to the top of the fixing seat 2. A connecting shaft 305 is movably connected inside the fixing shell 301. The connecting shaft 305 can rotate inside the fixing shell 301 and can rotate inside the fixing seat 2. A second driven gear 303 is fixedly connected to the upper outer side of the connecting shaft 305, and a first driven gear 304 is fixedly connected to the lower outer side of the connecting shaft 305. A top column 306 is movably connected to the upper part of the inside of the fixed housing 301. The top column 306 meshes with the second driven gear 303. A driving gear 302 meshes with the first driven gears 304. A placement sleeve 7 is installed on the surface of the fixed base 2. The rotation of the driving gear 302 can drive the four first driven gears 304 to rotate, thereby causing the four connecting shafts 305 to rotate, and causing the second driven gears 303 to rotate.

[0025] Furthermore, the top post 306 includes a column 3061 movably connected to the upper part of the fixed housing 301. A top block 3062 is fixedly connected to the outer end of the column 3061. The top block 3062 is made of rubber and has a certain anti-slip function. A fixed tooth 3063 is fixedly connected to the side of the column 3061 near the second driven gear 303. The forward and reverse rotation of the second driven gear 303 allows the column 3061 to move back and forth inside the fixed housing 301. When the bottle mouth of the plastic bottle is inserted into the outside of the fixing device 3, the column 3061 moves outward, allowing the top block 3062 to press against the inner wall of the plastic bottle mouth, thereby fixing the plastic bottle. Since the bottle mouth of the plastic bottle is relatively hard, it will not deform due to compression and will not obstruct the outside of the plastic bottle, ensuring that the outside of the plastic bottle can be fully sprayed.

[0026] Furthermore, the bottom box 1 includes a box body 101. A support column 102 is fixedly connected to the lower part of the box body 101. A gear sleeve 107 is movably connected to the outer side of the box body 101. The gear sleeve 107 can rotate on the outer side of the box body 101. A connecting block 106 is fixedly connected to the outer side of the gear sleeve 107. The connecting block 106 is used to fixally connect to the slide rail 4. A rotating motor 103 is fixedly connected inside the box body 101. A rotating shaft 104 is fixedly connected to the output end of the rotating motor 103. A rotating gear 105 is fixedly connected to the top of the rotating shaft 104. The rotating gear 105 meshes with the gear sleeve 107. By starting the rotating motor 103, the rotating shaft 104 can drive the rotating gear 105 to rotate. The rotation of the rotating gear 105 can drive the gear sleeve 107 to rotate, which in turn can drive the slide rail 4 and the lifting frame 5 to rotate, so that the spraying device 6 can rotate, which is convenient for spraying the outer periphery of the plastic bottle.

[0027] Furthermore, the fixing base 2 includes a base 201 fixedly connected to the top of the housing 101. A drive motor 202 is fixedly connected inside the base 201. A drive shaft 203 is fixedly connected to the output end of the drive motor 202. The drive shaft 203 is fixedly connected to the drive gear 302. A slide column 205 is fixedly connected to the inner side of the fixing shell 301. The slide column 205 is used to accommodate the lifting and lowering of the sleeve 7. A spring 204 is movably sleeved on the outer side of the slide column 205. By starting the drive motor 202, the drive shaft 203 can drive the drive gear 302 to rotate. The diameter of the base 201 and the fixing shell 301 is adapted to the inner diameter of the bottle mouth of the plastic bottle, so that the plastic bottle can be inserted into the outer side of the base 201 and the fixing shell 301.

[0028] Furthermore, the slide rail 4 includes a rail body 401 fixedly connected to the rear side of the connecting block 106. A storage battery 403 is fixedly connected to the left side of the rail body 401. The storage battery 403 is used to power the lifting motor 404. The lifting motor 404 is fixedly connected to the lower part of the rail body 401. A stud 402 is fixedly connected to the output end of the lifting motor 404. By starting the lifting motor 404, the stud 402 can be rotated. By rotating forward and backward, the lifting block 502 can be raised and lowered, thereby adjusting the height of the spraying device 6 to facilitate spraying the outer periphery of the plastic bottle.

[0029] Furthermore, the lifting frame 5 includes a lifting block 502 threadedly connected to the outside of the stud 402. The rear side of the lifting block 502 is fixedly connected to the frame body 501. The upper part of the frame body 501 is provided with a fixing groove 503, which is used to fix the spraying device 6.

[0030] Furthermore, the spraying device 6 includes a paint tank 601 fixedly connected to the upper part of the frame 501. A feed pipe 602 is fixedly connected to the top of the paint tank 601. By opening the feed pipe 602, paint can be poured into the paint tank 601. A spray pipe 604 is fixedly connected to the lower part of the paint tank 601. A spray pump 603 is installed on the outside of the spray pipe 604. A nozzle 605 is fixedly connected to the lower end of the feed pipe 602. By starting the spray pump 603, the paint in the paint tank 601 can be sprayed from the nozzle 605 through the spray pipe 604 onto the plastic bottle. Driven by the lifting motor 404 and the rotating motor 103, it can rotate and lift, thereby enabling it to spray paint on various parts of the outside of the plastic bottle.

[0031] Furthermore, the placement sleeve 7 includes a slider 702 movably connected to the outside of the slide column 205. The slider 702 can move up and down outside the slide column 205. The outer end of the slider 702 is fixedly connected to the sleeve body 701. The lower part of the slider 702 is fixedly connected to the spring 204. In use, the bottle mouth of the plastic bottle is inserted into the outside of the base body 201 and the fixing shell 301. As it moves downward, it can push the placement sleeve 7 downward, thereby squeezing the spring 204. When the sleeve body 701 moves to the bottom, the fixing device 3 can be controlled to fix the plastic bottle. After the spraying is completed, the fixing device 3 is controlled to remove the fixation of the plastic bottle. Under the action of the spring 204, the placement sleeve 7 can move upward, thereby pushing the plastic bottle upward, making it easy to remove the plastic bottle.

[0032] Working principle: During use, the bottle neck of the plastic bottle is inserted into the outer side of the base 201 and the fixing shell 301. As it moves downwards, it pushes the placement sleeve 7 downwards, thus compressing the spring 204. When the sleeve 701 reaches its lowest point, the drive motor 202 is activated, causing the drive shaft 203 to rotate the drive gear 302. The rotation of the drive gear 302 then drives the four first driven gears 304, which in turn rotate the four connecting shafts 305, causing the second driven gears 303 to rotate. The forward and reverse rotation of the second driven gears 303 allows the column 3061 to move back and forth inside the fixing shell 301, allowing the top block 3062 to press against the inner wall of the plastic bottle neck. This allows the system to secure the plastic bottle. Because the bottle opening is relatively rigid, it will not deform due to compression and will not obstruct the outer side of the plastic bottle, ensuring that the outer side of the plastic bottle can be fully sprayed. Then, the spray pump 603 is started so that the paint in the paint tank 601 can be sprayed onto the plastic bottle from the nozzle 605 through the spray pipe 604. Driven by the lifting motor 404 and the rotating motor 103, it can rotate and lift, thereby enabling it to spray all parts of the outer side of the plastic bottle. After the spraying is completed, the column 3061 retracts into the fixing shell 301, thereby removing the fixation on the plastic bottle. Under the action of the spring 204, the placement sleeve 7 can move upward, thereby pushing the plastic bottle upward, making it easy to remove the plastic bottle.
