Description

Technical Field

[0001] This invention belongs to the field of bath bottle molding technology, specifically a high-efficiency casting molding device for bath bottle production. Background Technology

[0002] PET bottles are plastic bottles made from polyethylene terephthalate (PET) as a raw material. Due to the use of PET plastic, PET bottles are lightweight, highly transparent, impact-resistant, and not easily broken. Therefore, PET bottles are commonly used as containers in the current production of shower gels.

[0003] Currently, existing shower bottles are blow-molded in one piece using a blow molding device. During the blow molding process, a threaded layer is formed on the surface of the bottle mouth to connect with the cap. This allows the shower bottle to be opened by turning the cap. While this is not a problem for home use, where the cap can be opened easily, it is problematic in high-traffic areas such as bathhouses and hotels. These shower bottles, which can be opened a second time, are easily opened by people who can fill them with unsanitary substances. This is difficult for cleaning staff to detect, and even if the shower bottle is opened, it is impossible to detect whether there are foreign substances inside.

[0004] Therefore, the present invention provides a high-efficiency casting molding device for the production of bath bottles. Summary of the Invention

[0012] Preferably, a bottle cap is movably fitted onto the top outer surface of the bath bottle, a pump head is provided inside the bottle cap, and multiple chamfer strips are provided on the outer surface of the bath bottle.

[0013] Preferably, the outer surface of the bath bottle is provided with a raised strip, the surface of the bottle cap is provided with a chamfered groove that is movably fitted onto the outer surface of the chamfered strip, and the bottom surface of the bottle cap is provided with a flexible strip.

[0014] Preferably, the left and right sides of the transmission disk are respectively provided with conveying channels, a hydraulic rod II is fixedly installed inside the conveying channel, an arc plate is provided at the output end of the hydraulic rod II, and two sets of discharge grooves are opened on the bottom surface of the transmission disk.

[0015] Preferably, the connection between the conveying channel and the transmission disk is provided with an inclined groove in the clockwise rotation direction of the motor, and an opening is provided on the outer surface of the transmission disk at the top edge of the discharge groove.

[0016] The beneficial effects of this invention are as follows: 1. The present invention discloses a high-efficiency casting molding device for producing bath bottles. After the bath bottle is defined, a pair of semi-circular mating plates are pushed by a hydraulic rod, so that the surface of the semi-circular mating plates is attached to the surface of the bottle mouth of the bath bottle. At this time, liquid TPE plastic is injected into the extrusion cavity and the extrusion chamfer groove by a TPE extruder. The liquid TPE plastic fills the gap inside the extrusion chamfer groove and adheres to the bottle mouth of the bath bottle. The high temperature softens the surface of the bottle mouth of the bath bottle. Under the constraint of the inner ring sleeve, the bottle mouth of the bath bottle can be effectively prevented from deforming under subsequent high temperature extrusion. 2. The high-efficiency casting molding device for producing bath bottles according to the present invention, after the TPE plastic fills the extrusion chamfered groove, a water pump injects low-temperature water into the hollow sleeve through a water pipe, while excess air inside the hollow sleeve is discharged through an exhaust pipe. The low-temperature water absorbs heat from the TPE plastic inside the extrusion chamber through the hollow sleeve, causing the TPE plastic to solidify rapidly. The TPE plastic remaining inside the extrusion chamfered groove also gradually solidifies as the temperature decreases. Meanwhile, the extrusion channel inside the extrusion chamfer groove is relatively narrow, which allows the TPE plastic inside the extrusion chamfer groove to be better separated from the TPE plastic inside the extrusion chamber. This allows the TPE plastic inside the extrusion chamfer groove to remain on the surface of the shower bottle, thus forming an inverted chamfer strip. After the shower bottle and the cap are joined together, the chamfer strip will be inverted and snapped into the inside of the chamfer groove. When external force needs to peel off the cap, the inverted chamfer strip can effectively prevent the cap from being opened a second time. 3. The high-efficiency casting molding device for producing bath bottles according to the present invention, when the bath bottle enters the limiting groove on the surface of the polygonal turntable under the push of the hydraulic rod two, the polygonal turntable is rotated in conjunction with the motor. Since the polygonal turntable is an octagonal rectangle, when it rotates inside the circular transmission plate, a certain gap will be left between the polygonal turntable and the transmission plate. As the polygonal turntable continues to rotate, the extrusion rod on the outer surface of the polygonal turntable will slide on the surface of the inclined groove, and the R-shaped round head at one end of the extrusion rod will gradually move inward towards the inside of the groove under the traction of the inclined groove. The moving extrusion rod will extrude and push the R-shaped round corner on the surface of one end of the push rod, and cause the push rod to drive the silicone soft plate to move towards the center position. At this time, the silicone soft plate is attached to the outer surface of the bath bottle, thereby extruding and limiting the position of the bath bottle. 4. The efficient casting molding device for producing bath bottles according to the present invention, after the surface of the bath bottle is injection molded, the bath bottle will move continuously under the drive of the polygonal turntable. When the bath bottle moves to the top of the discharge groove, the bath bottle at the bottom surface of the hydraulic push rod will repeat the above operation. When it moves to the top of the discharge groove, the outer surface of the extrusion rod will be inside the opening. Without external resistance, the elastic wire on the outer surface of the limiting plate will push the extrusion rod in the opposite direction and move the extrusion rod away from one end surface of the push rod. At this time, the silicone soft plate will unfold under its own elasticity. Without the limiting of the silicone soft plate, the bath bottle will fall directly into the outside through the discharge groove and be recycled, and the inside of the bath bottle will be filled with bath liquid.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figure 2 , Figures 4 to 5 and Figure 9 - Figure 11 As shown in the figure, an efficient casting molding device for producing bath bottles according to an embodiment of the present invention includes a support platform 11 and a motor 12 disposed on the outer surface of the top of the support platform 11, a bath bottle 14 disposed inside the support platform 11, a TPE extruder 111 disposed on the top surface of the support platform 11, and hydraulic push rods 112 disposed on the top surface of the support platform 11 and at the two side edges of the TPE extruder 111. The output end of the hydraulic push rod 112 is fixedly connected to an inner ring sleeve 113 that is movably sleeved on the inner wall of the bath bottle 14. Two sets of hydraulic rods 114 are provided on the top surface and at the bottom edge of the hydraulic push rod 112. The output end of the hydraulic rod 114 is fixedly connected to a semi-circular docking plate 115 that is movably sleeved on the outer surface of the bath bottle 14. The outer surface of the semi-circular docking plate 115 is provided with an extrusion chamfered groove 116. The interior of the semi-circular docking plate 115 is provided with an extrusion cavity 117 that communicates with the extrusion chamfered groove 116. The infusion end of the TPE extruder 111 is connected to the interior of the extrusion cavity 117. The top surface of the semi-circular docking plate 115 is provided with a sealing cap 118. A hollow sleeve a1 is provided on the bottom surface of the sealing cover 118. A high-temperature heater a2, a water pipe a5 and an exhaust pipe a6 are respectively provided on the surface of the sealing cover 118. A heat-conducting roller a3 is fixedly connected to the output end of the high-temperature heater a2. A heat-conducting plate a4 is fixedly connected to the outer surface of the hollow sleeve a1 on the outer surface of the heat-conducting roller a3.

[0022] When the bath bottle 14 moves to the bottom edge of the hydraulic push rod 112, it works in conjunction with the hydraulic push rod 112 to push the inner ring sleeve 113, so that the inner ring sleeve 113 is fitted onto the entrance of the bath bottle 14, and the outer surface of the inner ring sleeve 113 is fitted into the inner wall of the bath bottle 14. The inner ring sleeve 113 can limit the entrance of the bath bottle 14 and form two-point positioning with the polygonal turntable 121, so as to provide stability when the bath bottle 14 is injection molded. Once the shower bottle 14 is positioned, the hydraulic rod 114 pushes the semi-circular mating plate 115, causing the surface of the semi-circular mating plate 115 to adhere to the bottle neck surface of the shower bottle 14. At this time, the TPE extruder 111 injects liquid TPE plastic into the extrusion cavity 117 and the extrusion chamfer groove 116. The liquid TPE plastic fills the gap inside the extrusion chamfer groove 116 and adheres to the bottle neck of the shower bottle 14. The high temperature softens the surface of the bottle neck of the shower bottle 14, and the bottle neck of the shower bottle 14 is effectively prevented from deforming under subsequent high temperature extrusion by the inner sleeve 113. After the TPE plastic fills the extrusion chamfered groove 116, the water pump injects low-temperature water into the hollow sleeve a1 through water pipe a5. Excess air inside the hollow sleeve a1 is discharged through the exhaust pipe a6. The low-temperature water absorbs heat from the TPE plastic inside the extrusion chamber 117 through the hollow sleeve a1, causing the TPE plastic to solidify rapidly. The TPE plastic remaining inside the extrusion chamfered groove 116 also gradually solidifies as the temperature decreases. Simultaneously, the extrusion chamber 117 continues to extrude the TPE plastic inside the extrusion chamfered groove 116. The narrow channel allows the TPE plastic inside the extrusion chamfer groove 116 to be better separated from the TPE plastic inside the extrusion cavity 117, and the TPE plastic inside the extrusion chamfer groove 116 remains on the surface of the shower bottle 14, thus forming an inverted chamfer strip 143. After the shower bottle 14 is connected to the bottle cap 141, the chamfer strip 143 will be inverted and locked into the inside of the chamfer groove 145. When external force needs to peel off the bottle cap 141, the inverted chamfer strip 143 can effectively prevent the bottle cap 141 from being opened a second time. After the chamfer strip 143 is injection molded on the surface of the bath bottle 14, the water pump will extract the water inside the hollow sleeve a1 through the water pipe a5. At this time, the high temperature heater a2 will heat the heat-conducting roller a3 at high temperature. The high temperature will evaporate the residual water inside the hollow sleeve a1, and the high temperature on the surface of the heat-conducting roller a3 will be directly transferred to the TPE plastic surface inside the extrusion cavity 117 through the heat-conducting plate a4, and the residual TPE plastic inside the extrusion cavity 117 will be softened at high temperature. The hollow sleeve a1 is positioned inside the semi-circular mating plate 115. The entire semi-circular mating plate 115 will limit the outer surface of the hollow sleeve a1, so that even if the internal pressure is high, the hollow sleeve a1 will not be broken. Furthermore, the inlet of water pipe A5 is located at the bottom of the hollow sleeve A1, and the water source will only spread upwards from the bottom. This ensures that the vaporization and pressure increase are gradual and step-like, rather than a sudden and drastic increase, allowing for sufficient gas emission. TPE plastic, as a thermoplastic, can be repeatedly cured and hot-melted, while also possessing good water and chemical resistance. A TPE extruder is a plastic processing equipment specifically designed to process TPE thermoplastic elastomer granules into continuous cross-section products. TPE material combines the elasticity of rubber with the processing convenience of plastic. TPE granules enter the feeding section of the extruder from the hopper. In this stage, the rotation of the screw mechanically shears and agitates the material, causing it to form a solid plug and be conveyed forward. Maintaining a low temperature is to prevent the material from melting too early and causing the screw to slip, thus ensuring the uniformity of the extrusion volume and the stability of plasticization. As the material enters the melting and homogenizing sections, the barrel temperature increases significantly. Under the combined action of the heat from the external heating coil and the intense mechanical shear heat generated by the screw rotation, the TPE granules undergo an aggregation state transformation, gradually changing from a solid state to a uniform viscous melt. The homogenizing section further compacts and mixes the melt evenly, providing a stable melt flow for subsequent extrusion. The uniformly plasticized TPE melt enters the die head and mold under the continuous forward thrust of the screw. The melt is compressed and compacted in the mold and finally continuously extruded through a die of a specific shape to form the required cross-sectional profile. The high-temperature TPE profile extruded from the die is in a soft state and must be immediately placed into a cooling system (such as a water tank or air-cooling device). It is cured by rapid cooling. Subsequently, the traction device pulls the profile out at a uniform speed matched with the extrusion speed, and finally the cutting equipment cuts it to the required length or rolls it up.

[0023] like Figures 8 to 11As shown, a bottle cap 141 is movably fitted onto the top outer surface of the bath bottle 14. A pump head 142 is provided inside the bottle cap 141. Multiple chamfer strips 143 are provided on the outer surface of the bath bottle 14. A raised strip 144 is provided on the outer surface of the bath bottle 14. A chamfered groove 145 is provided on the surface of the bottle cap 141, which is movably fitted onto the outer surface of the chamfer strips 143. A flexible strip 146 is provided on the bottom surface of the bottle cap 141.

[0024] The extrusion temperature of TPE plastic is usually 160~200℃. After injection molding, when it comes into contact with the PET bottle mouth (softening point about 70~80℃), the surface of the bottle mouth will soften to facilitate TPE adhesion. After extrusion, 5~15℃ low temperature water is introduced through a hollow sleeve to quickly cool the TPE to about 50℃ and enter a semi-solid state. At this temperature, the TPE plastic is in a gel-like semi-solid state and can be moved slightly. After the movement, it will also return to its original shape by its own rebound. After the chamfer strip 143 is shaped, the bottle cap 141 is put on the surface of the bath bottle 14. At this time, the temperature inside the chamfer strip 143 has not been completely cooled and solidified. Under the pressure of the bottle cap 141, the chamfer strip 143 will be stuck into the chamfer groove 145. At this time, the chamfer of the chamfer strip 143 will lock the bottle cap 141 firmly in place, so that the bottle cap 141 cannot be opened manually under normal use. Since the chamfer strip 143 and the shower bottle 14 are not integrally cast, but are extruded from TPE plastic later, the two are not completely stable. When the surface of the chamfer strip 143 is subjected to a tensile limit, it will detach. After the chamfer strip 143 is detached, the shower bottle 14 and the cap 141 will be in a movable state. Cleaning staff only need to lift the cap 141 to find out whether the shower bottle 14 and the cap 141 have been opened by external force. If the surface of the cap 141 is damaged, it will also leave a mark of damage. Once discovered, the shower bottle 14 can be replaced in time. Furthermore, once the bottle cap 141 and the bath bottle 14 are properly connected, the soft strip 146 on the bottom surface of the bottle cap 141 presses against the anti-leak ring on the surface of the bath bottle 14, completely sealing the gap between the bottle cap 141 and the bath bottle 14. This prevents external liquid substances from entering the interior of the bath bottle 14 through the gap left between the bath bottle 14 and the bottle cap 141.

[0025] like Figures 1 to 3 , Figure 6 - Figure 7 and Figure 12As shown, a transmission disk 13 is provided on the inner side wall of the top of the support platform 11. A polygonal turntable 121 is fixedly connected to the output end of the motor 12 and movably sleeved on the inner side wall of the transmission disk 13. Multiple grooves are formed on the outer surface of the polygonal turntable 121. A semi-circular limiting plate 122 is fixedly connected to the inner side wall of the groove. Silicone flexible plates 123 are oscillatingly connected to the outer surfaces of both ends of the semi-circular limiting plate 122. A slot 124 is formed on the outer surface of the polygonal turntable 121 and at the edge of the outer surface of the silicone flexible plate 123. A push rod 125 is fixedly connected to the outer surface of 23 and is movably sleeved inside the groove 124. A limit plate 126 is fixedly connected to the inner wall of the groove 124. A slide rod 127 is movably sleeved on the outer surface of the limit plate 126. A pressing rod 129 is fixedly connected to both ends of the slide rod 127. An elastic wire 128 is movably sleeved on the outer surface of the slide rod 127. An R-shaped round head 1210 is provided at one end of the pressing rod 129. The outer surfaces of the semi-circular limit plate 122 and the silicone soft plate 123 are movably attached to the outer surface of the bath bottle 14. The left and right sides of the transmission disk 13 are respectively provided with conveying channels 131. A hydraulic rod 133 is fixedly installed inside the conveying channel 131. An arc plate 134 is provided at the output end of the hydraulic rod 133. Two sets of discharge grooves 132 are provided on the bottom surface of the transmission disk 13. An inclined groove 135 is provided at the connection between the conveying channel 131 and the transmission disk 13 in the clockwise rotation direction of the motor 12. An opening 136 is provided on the outer surface of the transmission disk 13 at the top edge of the discharge groove 132.

[0026] When the bath bottle 14 is pushed into the limiting groove on the surface of the polygonal turntable 121 by the hydraulic rod 133, the polygonal turntable 121 is rotated by the motor 12. Since the polygonal turntable 121 is an octagonal rectangle, a certain gap will remain between the polygonal turntable 121 and the transmission plate 13 when it rotates inside the circular transmission plate 13. As the polygonal turntable 121 continues to rotate, the extrusion rod 129 on the outer surface of the polygonal turntable 121 will slide on the surface of the inclined groove 135. The R-shaped round head 1210 at one end of the extrusion rod 129 will gradually move inward towards the inside of the groove 124 under the traction of the inclined groove 135. The moving extrusion rod 129 will extrude and push the R-shaped round corner on one end of the push rod 125, and cause the push rod 125 to drive the silicone soft plate 123 to move towards the center position. At this time, the silicone soft plate 123 is attached to the outer surface of the bath bottle 14, thereby extruding and limiting the position of the bath bottle 14. After the surface of the bath bottle 14 is injection molded, the bath bottle 14 will move continuously under the drive of the polygonal turntable 121. When the bath bottle 14 moves to the top of the discharge groove 132, the bath bottle 14 at the bottom surface of the hydraulic push rod 112 will repeat the above operation. When it moves to the top of the discharge groove 132, the outer surface of the extrusion rod 129 will be inside the opening 136. Without external resistance, the elastic wire 128 on the outer surface of the limiting plate 126 will push the extrusion rod 129 in the opposite direction and move the extrusion rod 129 away from one end surface of the push rod 125. At this time, the silicone soft plate 123 will unfold under its own elasticity. Without the limitation of the silicone soft plate 123, the bath bottle 14 will fall directly into the outside through the discharge groove 132 and be recycled, and the bath bottle 14 will be filled with bath liquid.

[0027] Working principle: The bath bottle 14 is molded using a molding machine. After molding, the bath bottle 14 undergoes air-cooling and curing treatment, and is then placed inside the conveying channel 131. The conveying channel 131 sequentially transports the bath bottles 14, and hydraulic rod 133 pushes the arc-shaped plate 134, thereby pushing the bath bottles 14 inside the conveying channel 131 into the semi-circular limiting plate 122. At this time, motor 12 rotates the polygonal turntable 121, allowing the inner wall of the conveying plate 13 to guide the bath bottle 14 to its designated position. The line limit can effectively prevent excessive shaking of the bath bottle 14. When the bath bottle 14 moves to the bottom edge of the hydraulic push rod 112, the inner ring sleeve 113 is moved into the bottle mouth of the bath bottle 14 in conjunction with the hydraulic push rod 112, and the bottle mouth of the bath bottle 14 is limited. Subsequently, the semi-circular mating plate 115 is pushed in conjunction with the hydraulic rod 114, so that the semi-circular mating plate 115 is sleeved on the bottle mouth surface of the bath bottle 14. At this time, the threaded layer is removed during the molding process at the bottle mouth surface of the bath bottle 14, and the bottle mouth is in a smooth state. Once the position of the bottle opening of the shower bottle 14 is defined, the TPE extruder 111 is used to extrude TPE plastic into the extrusion chamber 117 and the extrusion chamfered groove 116. The softened TPE plastic will adhere to the surface of the shower bottle 14, making the two fit tightly together. As the TPE plastic gradually fills the interior of the extrusion chamfered groove 116, it will be shaped according to the shape inside the extrusion chamfered groove 116. Since TPE plastic can be extruded at a temperature of 100°C, this temperature softens the bottle neck when it comes into contact with the surface of the shower bottle 14. At this time, the interior of the shower bottle 14, constrained by the inner sleeve 113, will not deform due to external pressure. As the softened TPE plastic adheres to the rear surface of the shower bottle 14, the cooling device cools the molded TPE plastic to 50°C. At this temperature, the TPE plastic is in a semi-solid, gel-like state, allowing for slight oscillation. After oscillation, it will rebound on its own. After the chamfer strip 143 is shaped, the shower bottle 14 is moved into the shower liquid injection device to fill it with shower liquid. After the shower liquid is filled, the bottle cap 141 is put onto the surface of the shower bottle 14. At this time, the temperature inside the chamfer strip 143 has not been completely cooled and solidified. Under the pressure of the bottle cap 141, the chamfer strip 143 will be stuck into the chamfer groove 145. At this time, the chamfer of the chamfer strip 143 will firmly lock the bottle cap 141 in place, so that the bottle cap 141 cannot be opened manually under normal operation. Since the chamfer strip 143 and the shower bottle 14 are not integrally cast, but are extruded from TPE plastic later, the two are not completely stable. When the surface of the chamfer strip 143 is subjected to a tensile limit, it will detach. After the chamfer strip 143 is detached, the shower bottle 14 and the cap 141 will be in a movable state. Cleaning staff only need to lift the cap 141 to find out whether the shower bottle 14 and the cap 141 have been opened by external force. If the surface of the cap 141 is damaged, it will also leave a mark of damage. Once discovered, the shower bottle 14 can be replaced in time. When the shower gel inside the shower bottle 14 is used up, the tight snap-fit ​​between the shower bottle 14 and the cap 141 can effectively prevent the empty bottle from being recycled and refilled with substandard shower gel to manufacture defective products.
