[0009] Preferably, an L-shaped guardrail is fixedly connected between the outer wall of one end of the bellows and the side wall of the other end of the bulb clamp mold, a positioning guardrail is fixedly connected to the bottom side wall of the bellows, and the bottom end of the positioning guardrail is fixedly connected to the inner wall of one end of the U-shaped plate frame.

[0010] Preferably, each of the surface scraper structures includes a spring fixedly connected to the inner wall of the other end of the hollow cylinder, the other end of the spring is fixedly connected to the outer wall of one end of the inflatable cylinder rod, and a resistance plate is provided in the inner cavity of the inflatable cylinder rod.

[0011] Preferably, T-shaped slides are fixedly connected to the outer walls at both ends of the resistance plate, and T-shaped slide grooves are provided in the inner walls at both ends of the inflatable cylinder rod for sliding engagement with the two T-shaped slides. A sliding rod is slidably connected through the center of the resistance plate, and bent resistance rods are fixedly connected to the outer walls on both sides of one end of the resistance plate.

[0012] Preferably, a sleeve rod is movably connected to the rod body of the bending abutment rod, and the bottom end of the sleeve rod is fixedly connected to the inner wall of the bottom end of the inflatable cylinder rod. A wind wheel is also movably connected to the rod body of the sliding rod, and an annular scraper is fixedly connected to one end of the wind wheel. A side plate of the annular scraper is fit-connected to the outer wall of the other end of the cylinder mouth of the inflatable cylinder rod.

[0013] Preferably, each of the refrigeration structures comprises a telescopic rod disc threadedly connected to a side rod of the bidirectional screw, and a cold collecting box is slidably connected through the rod body of the telescopic rod disc.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention contacts the hollow plastic through the inflating cylinder rod in the bulb clamp mold, thereby penetrating one end of the hollow plastic to facilitate subsequent inflation. When the bulb clamp mold is passively moved, the L-shaped fence plate is simultaneously driven to translate, thereby squeezing the bellows positioned at one end by the positioning fence plate, so that the gas in the inner cavity is compressed to pass through the L-shaped air pipe and the hollow cylinder, and finally out of the inflating cylinder rod. Then, when the gas is forced into the hollow plastic, the hollow plastic can be prevented from being bonded in advance during the blanking process of the hollow plastic and when the two bulb clamp molds are moved.

[0018] The present invention allows the inflatable cylinder rod to retract in the hollow cylinder, thereby squeezing the spring. The spring is convenient for automatically driving the inflatable cylinder rod to reset later. The gas that enters the inflatable cylinder rod through the L-shaped air pipe will immediately push the abutment plate and the T-shaped slide plates installed on both ends, so that both can slide in the corresponding T-shaped slide grooves, thereby assisting the abutment plate to move horizontally on the slide rod, thereby driving the two bent abutment rods to move horizontally and fit with the wind wheel to block the gas from escaping from the inflatable cylinder rod. The gas drives the wind wheel and the annular scraper to rotate , thereby preventing the ring scraper from rotating, and when the plastic that may be adhered to the mouth of the inflation tube is rotated and scraped off, the cleaned plastic material will naturally fall down and adhere to the plastic bulb formed by being inflated in the bulb clamp mold. In addition, the perforation position of the plastic material of the device is located at the corner position of the extrusion molding, and the perforation and inflation are not performed on the surface of the bulb, which further ensures the production quality and integrity of the plastic bulb, and can prevent the bulb from sinking due to water entering when it is used in the pool later, and the bulb does not have the floating function event;

[0019] When the bidirectional screw is rotated, the telescopic rod disk is also driven to move. The movement of the telescopic rod disk reaches a limited translation in the cold collecting box. When the telescopic rod disk is passively reset, once it fits and abuts against one end of the U-shaped plate frame, the bulb clamp mold and the cold collecting box will also move a certain distance synchronously, thereby enabling the sealing plug to intermittently detach from one end of the bulb clamp mold, so that a small amount of mass agent in the cold collecting box naturally flows into the rectangular groove in the bulb clamp mold, thereby cooling the inner cavity of the bulb clamp mold and accelerating the shaping speed of the inflated plastic bulb.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 8As shown, the present invention provides a ball bubble inflation molding device, including a plastic ball bubble molding machine 1, the plastic ball bubble molding machine 1 is provided with an inflation molding part 2, the inflation molding part 2 includes a U-shaped plate frame 21 that is fitted and slidably connected to the plastic ball bubble molding machine 1, a motor 22 is fixedly connected to the outer wall of one end of the U-shaped plate frame 21, a bidirectional screw 23 is fixedly connected to the rotating shaft of the motor 22, the rod body of the bidirectional screw 23 and the plate body of the U-shaped plate frame 21 are movably sleeved, and sliding plates 24 are threadedly connected to the rod bodies on both sides of the bidirectional screw 23, a U-shaped rod frame 25 is fixedly connected to the outer wall of the top end of the U-shaped plate frame 21, the U-shaped rod frame 25 and the two sliding plates 24 are through-slidably connected, and the top outer walls of the two U-shaped rod frames 25 are fixedly connected to ball bubble clamp molds 26;

[0033] A group of bulb clamp molds 26 are all provided with an inflatable structure capable of inflating and molding hollow plastics, one end of each inflatable structure is provided with a surface scraping structure, and a group of bulb clamp molds 26 are also provided with a refrigeration structure.

[0034] The above scheme is adopted: the plastic bulb forming machine 1 in the prior art is operated to extrude the plastic. At this time, the motor 22 in the U-shaped plate frame 21 is started to drive the bidirectional screw 23 to rotate. The rotating bidirectional screw 23 will simultaneously drive the two sliding plates 24 and the bulb clamp mold 26 to move in opposite directions, and the two sliding plates 24 will drive the two bulb clamp molds 26 to move horizontally with the assistance of the U-shaped rod frame 25, so that the two bulb clamp molds 26 can contact and extrude the hollow plastic being extruded.

[0035] Each inflatable structure includes an inflating cylinder rod 27 that is slidably connected to one end of the bubble clamp mold 26, a hollow cylinder 28 is slidably connected to the outer wall of one end of the inflating cylinder rod 27, the outer wall of the hollow cylinder 28 and the inner wall of the bubble clamp mold 26 are fixedly connected, and a rectangular groove 29 is opened in the side inner wall of the bubble clamp mold 26, an L-shaped air pipe 230 is fixedly connected to the other end of the hollow cylinder 28, the rod body of the L-shaped air pipe 230 and the other end of the bubble clamp mold 26 are fixedly connected, and a bellows 231 is fixedly connected to the other end of the tube body of the L-shaped air pipe 230, an L-shaped fence 232 is fixedly connected between the outer wall of one end of the bellows 231 and the side wall of the other end of the bubble clamp mold 26, a positioning fence 233 is fixedly connected to the bottom side wall of the bellows 231, and the bottom end of the positioning fence 233 is fixedly connected to the inner wall of one end of the U-shaped plate frame 21.

[0036] The above scheme is adopted: the inflation tube rod 27 in the bubble clamp mold 26 contacts the hollow plastic, thereby penetrating one end of the hollow plastic to facilitate subsequent inflation thereof. When the bubble clamp mold 26 moves passively, it will simultaneously drive the L-shaped fence 232 to translate, thereby squeezing the bellows 231 positioned at one end by the positioning fence 233, so that the gas in its inner cavity is pressurized to pass through the L-shaped air pipe 230 and the hollow tube 28, and finally out of the inflation tube rod 27. Then, when the gas is forced to enter the hollow plastic, the hollow plastic can be prevented from being bonded in advance during the hollow plastic unloading process and when the two bubble clamp molds 26 move. As the two bubble clamp molds 26 move, they contact and extrude the hollow plastic. At the same time, the two inflation tube rods 27 will also conflict with each other in advance and squeeze each other under force. The passively squeezed inflation tube rod 27 will shrink in the hollow tube 28.

[0037] Each surface scraper structure includes a spring 234 fixedly connected to the inner wall of the other end of the hollow cylinder 28, the other end of the spring 234 is fixedly connected to the outer wall of one end of the inflatable cylinder rod 27, a plate 235 is provided in the inner cavity of the inflatable cylinder rod 27, and T-shaped slide plates 236 are fixedly connected to the outer walls of both ends of the plate 235. T-shaped grooves 237 that are slidably engaged with the two T-shaped slide plates 236 are provided in the inner walls of both ends of the inflatable cylinder rod 27. The center of the plate 235 is penetrated by a through hole. A sliding rod 238 is slidably connected, and a bent push rod 239 is fixedly connected to the outer walls on both sides of one end of the push plate 235. A sleeve rod 240 is movably sleeved on the rod body of the bent push rod 239. The bottom end of the sleeve rod 240 is fixedly connected to the bottom inner wall of the inflatable cylinder rod 27. A wind wheel 241 is also movably sleeved on the rod body of the sliding rod 238. A ring scraper 242 is fixedly connected to one end of the wind wheel 241. One side plate of the ring scraper 242 is fit-connected to the outer wall of the other end of the cylinder mouth of the inflatable cylinder rod 27.

[0038] The above scheme is adopted: the inflatable cylinder rod 27 retracts in the hollow cylinder 28, thereby squeezing the spring 234. The spring 234 is convenient for automatically driving the inflatable cylinder rod 27 to reset subsequently, and the gas entering the inflatable cylinder rod 27 through the L-shaped air pipe 230 will immediately push the resistance plate 235 and the T-shaped slide plates 236 installed on both ends, so that both can slide in the corresponding T-shaped slide grooves 237, thereby assisting the resistance plate 235 to move horizontally on the slide rod 238, thereby driving the two bent resistance rods 239 to move horizontally, and then fit and engage with the wind wheel 241 to block the gas from escaping from the inflatable cylinder rod 27. The gas drives the wind wheel 241 and the annular scraper 242 to rotate, thereby preventing the annular scraper 242 from rotating. When the plastic that may be adhered to the cylinder mouth of the inflatable cylinder rod 27 is rotated and scraped off, the cleaned plastic material will naturally discharge and adhere to the plastic bubble formed by being inflated in the bubble clamp mold 26.

[0039] Each refrigeration structure includes a telescopic rod disc 243 threadedly connected to the side rod of the bidirectional screw 23, and a cold collecting box 244 is slidably connected to the rod body of the telescopic rod disc 243. The cold collecting box 244 and the other end outer wall of the bulb clamp mold 26 are fixedly connected, and a plug plate is penetrated and clamped on the outer wall of one end of the cold collecting box 244. A sealing plug 245 is fixedly connected to the rod body at the other end of the telescopic rod disc 243, and the sealing plug 245 and the other end outer wall of the bulb clamp mold 26 are intermittently penetrated and clamped.

[0040] The above scheme is adopted: when the bidirectional screw 23 rotates, it will also drive the telescopic rod disc 243 to move. The movement of the telescopic rod disc 243 will reach a limited translation in the cold collecting box 244. When the telescopic rod disc 243 is passively reset, once it fits and contacts one end of the U-shaped plate frame 21, the bulb clamp mold 26 and the cold collecting box 244 will also move a certain distance synchronously, thereby enabling the sealing plug 245 to intermittently detach from one end of the bulb clamp mold 26, so that a small amount of the mass agent in the cold collecting box 244 naturally flows into the rectangular groove 29 in the bulb clamp mold 26, thereby cooling the inner cavity of the bulb clamp mold 26 and accelerating the molding speed of the inflated plastic bulb.

[0041] The working principle and use process of the present invention are as follows: the plastic bulb forming machine 1 in the prior art is operated to extrude the plastic. At this time, the motor 22 in the U-shaped plate frame 21 is started to drive the bidirectional screw 23 to rotate. The rotating bidirectional screw 23 will simultaneously drive the two sliding plates 24 and the bulb clamp mold 26 to move in opposite directions, and the two sliding plates 24 will drive the two bulb clamp molds 26 to move horizontally with the assistance of the U-shaped rod frame 25, so that the two bulb clamp molds 26 can contact and extrude the hollow plastic that is extruded and discharged. The inflation cylinder rod 27 in the bulb clamp mold 26 will first contact the hollow plastic, thereby penetrating one end of the hollow plastic to facilitate subsequent inflation. When the bulb clamp mold 26 is When the L-shaped fence 232 moves, it will also drive the L-shaped fence 232 to translate, thereby squeezing the bellows 231 positioned at one end by the positioning fence 233, so that the gas in its inner cavity is compressed and passes through the L-shaped air pipe 230 and the hollow cylinder 28, and finally out of the inflatable cylinder rod 27. Then, when the gas is forced to enter the hollow plastic, it can avoid the hollow plastic blanking process and the movement of the two bubble clamp molds 26, which will affect the early adhesion of the hollow plastic. As the two bubble clamp molds 26 move, they will contact and squeeze the hollow plastic. At the same time, the two inflatable cylinder rods 27 will also conflict with each other first and squeeze each other under force. The passively squeezed inflatable cylinder rod 27 will retract in the hollow cylinder 28, thereby squeezing the spring 234, which is convenient for Subsequently, the inflatable cylinder rod 27 is automatically driven to reset, and the gas entering the inflatable cylinder rod 27 through the L-shaped air pipe 230 will immediately push the stop plate 235 and the T-shaped slide plates 236 installed on both ends, so that both can slide in the corresponding T-shaped slide grooves 237, thereby assisting the stop plate 235 to move horizontally on the slide bar 238, thereby driving the two bent stop bars 239 to move horizontally, and then fit and engage with the wind wheel 241 to block the gas from escaping from the inflatable cylinder rod 27. The gas drives the wind wheel 241 and the annular scraper 242 to rotate, thereby preventing the annular scraper 242 from rotating, and when the plastic that may be adhered to the cylinder mouth of the inflatable cylinder rod 27 is rotated and scraped off, the cleaned plastic material will naturally flow out and adhere to the inflated In the plastic bulb formed in the bulb clamping mold 26, only when the bellows 231 is passively reset and negative pressure suction force is generated, the two bent abutting rods 239 are indirectly driven to separate from the wind wheel 241. At this time, the inflating cylinder rod 27 is also limited by the suction force to separate from the plastic bulb, so that the wind wheel 241 receives the suction force and rotates to scrape the material, avoiding the blockage of the inflating cylinder rod 27 and the accumulation of material to produce excessive perforations when penetrating the hollow plastic. In addition, the perforation position of the plastic material of the device is located at the corner position of the extrusion molding, rather than perforating and inflating the surface of the bulb, which further ensures the production quality and integrity of the plastic bulb, and can prevent the bulb from sinking into the water body and not having the floating function when it is used in the pool later.

[0042] When the bidirectional screw 23 rotates, it will also drive the telescopic rod disc 243 to move. The movement of the telescopic rod disc 243 will reach a limited translation in the cold collecting box 244. When the telescopic rod disc 243 is passively reset, once it fits and contacts one end of the U-shaped plate frame 21, the bulb clamp mold 26 and the cold collecting box 244 will also move a certain distance synchronously, thereby enabling the sealing plug 245 to intermittently detach from one end of the bulb clamp mold 26, so that a small amount of the mass agent in the cold collecting box 244 will naturally flow into the rectangular groove 29 in the bulb clamp mold 26, and the inner cavity of the bulb clamp mold 26 will be cooled to accelerate the shaping speed of the inflated plastic bulb. Finally, the plastic bulb molding machine 1 will push the U-shaped plate frame 21, so that the clamping mechanical arm on the plastic bulb molding machine 1 can facilitate the top clamping and transfer of a group of plastic bulbs in the bulb clamp mold 26. The specific operation process and principle of the plastic bulb molding machine 1 as a whole are all existing technical structures, which will not be elaborated here.
