Description

Technical Field

[0001] The invention belongs to the technical field of forming equipment, and in particular relates to a forming device for a pipe-structured air-conditioning insulation pipe and a processing method thereof. Background Art

[0002] Rubber-plastic insulation materials have excellent properties such as softness, heat resistance, flame retardancy, waterproofness, low thermal conductivity, shock absorption, and sound absorption. They are widely used in thermal insulation of central air-conditioning system equipment and containers in buildings. Air-conditioning insulation pipes often adopt single-tube and double-tube structures. They are made of rubber-plastic insulation materials through vulcanization and other processes and then extruded. However, after foaming, the rubber-plastic insulation material has low tear resistance. The construction process can easily destroy the integrity of the insulation material and reduce the performance of the insulation material. An outer protective layer is also required on its surface for protection. The outer protective layer is heated to a molten state in the extruder and then hot-melt composited with the surface of the insulation pipe.

[0003] However, the molten material is prone to generate bubbles during transportation, which affects the performance and service life of the outer sheath of the insulation pipe.

[0006] In the above-mentioned forming device for the air-conditioning thermal insulation pipe with a double-tube structure, a spring is welded between the outer wall of the floating frame and the inner wall of the transmission chamber.

[0007] In the above-mentioned forming device of a tube structure air-conditioning insulation pipe, the baffle plate 1 is slidably inserted at the transition between the extrusion channel and the forming mold, and the baffle plate 2 is slidably inserted at the transition between the extrusion channel and the return glue channel. A discharge port is provided on the outer wall of the baffle plate 1, and a return port is provided on the outer wall of the baffle plate 2. The spatial position of the discharge port is higher than the spatial position of the return port.

[0008] In the above-mentioned forming device for a tube-structured air-conditioning thermal insulation pipe, a stirring paddle is rotatably inserted into the end wall of the stirring rod.

[0009] In the above-mentioned forming device of a tube structure air-conditioning insulation tube, a feed channel is opened on the outer wall of the shell, and the feed channel extends into the storage chamber.

[0010] In the above-mentioned forming device of a tube structure air-conditioning insulation pipe, the exhaust mechanism includes an airbag, an airbag is bonded to the inner wall of the transmission chamber, the top outer wall of the airbag is bonded to the outer wall of the floating frame, air pipe one is welded to the top inner wall of the storage chamber, air pipe two is welded to the outer wall of the outer shell, the airbag is located between air pipe one and air pipe two, and the airbag is connected to both air pipe one and air pipe two.

[0011] In the above-mentioned forming device of a tube structure air-conditioning insulation pipe, a one-way air valve is arranged between the air pipe one and the air bag, an inverted conical hole is opened on the end wall of the air pipe one, a conical plug is slidably inserted in the conical hole, and a floating block is welded on the end wall of the conical plug.

[0012] In the above-mentioned forming device of a tube structure air conditioning insulation pipe, an exhaust port is opened on the end wall of the second air pipe, a sealing sleeve is welded on the outer wall of the floating frame, the sealing sleeve is slidably sleeved on the outer wall of the second air pipe, and an air hole is opened on the outer wall of the sealing sleeve.

[0013] A method for forming a tube-structured air-conditioning insulation pipe uses a forming device for a tube-structured air-conditioning insulation pipe as described above, and includes the following steps: first, the melted material is input into a feed channel, and the material enters a storage chamber along the feed channel; second, the air-conditioning pipe is inserted into a forming mold; third, the motor is started, and the motor drives the wedge block, the screw and the stirring rod to rotate synchronously; then, when it is necessary to increase or decrease the glue output, it is only necessary to control the motor speed to increase or decrease; finally, when the material is squeezed into the forming mold and formed into an outer protective layer, the air-conditioning pipe is then rolled up so that the molten outer protective layer adheres to the surface of the air-conditioning pipe to complete hot-melt compounding.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The floating frame is set up to drive the baffle plate 1 and baffle plate 2 to move up and down, so that the passage between the extrusion channel and the molding die is opened and closed reciprocally. At the same time, the screw continuously transports the material in the storage chamber to the bottom of the extrusion channel. In conjunction with the up and down reciprocating movement of the baffle plate 1, the glue discharge speed is controlled, thereby controlling the uniformity of the glue discharge during molding. When the glue discharge amount needs to be increased or decreased, it is only necessary to control the speed of the motor to increase or decrease, thereby avoiding the situation where the glue discharge speed is unstable and bubbles are generated; 2. By setting up the return glue channel, when the baffle plate 1 closes the passage between the extrusion channel and the molding die, the return material port on the baffle plate 2 opens the passage between the extrusion channel and the return glue channel, so that the screw pushes the material in the extrusion channel into the return glue channel. Since the inner diameter of the extrusion channel is larger than the inner diameter of the return glue channel, the extrusion force on the material increases, and the bubbles entrained in the material are pushed upward. At the same time, the stirring rod drives the stirring paddle to stir the material, further promoting the bubbles to float, and finally the gas in the bubbles is released into the material storage chamber, avoiding the situation of bubbles entrained in the material during molding; 3. Through the exhaust mechanism, as the bubbles gather in the upper layer of the material, the bubbles cannot provide enough buoyancy for the floating block, so that under the action of the floating block's own gravity, the floating block pulls the conical plug downward, thereby opening the air pipe one. At the same time, the floating frame reciprocates and compresses and stretches the air bag during the up and down reciprocating movement. When the air bag is stretched, the air holes on the sealing sleeve of the floating frame are staggered with the exhaust port on the air pipe two, so that the gas in the storage chamber is sucked into the air bag. When the air bag is compressed, the floating frame drives the air holes on the sealing sleeve to align with the exhaust port on the air pipe two, so that the gas is discharged through the air pipe two.

DETAILED DESCRIPTION

[0027] See also Figure 1-Figure 9The present invention provides a forming device for a pipe-structured air-conditioning insulation pipe, comprising a shell 1, wherein a transmission chamber 13 and a material storage chamber 11 are arranged in the interior of the shell 1, wherein an extrusion channel 111 is arranged at the bottom of the material storage chamber 11, wherein a return glue channel 112 extending to the material storage chamber 11 is arranged at the bottom of the extrusion channel 111, wherein the inner wall diameter of the extrusion channel 111 is larger than the inner wall diameter of the return glue channel 112, wherein a forming mold 113 is arranged on the outer wall of the shell 1, wherein the extrusion channel 111 is connected with the forming mold 113, wherein a motor 2 is welded on the outer wall of the top of the transmission chamber 13, wherein a wedge block 21, a stirring rod 23 and a screw 22 are welded on the outer wall of the main shaft of the motor 2 in sequence from top to bottom, wherein the screw 22 is rotatably inserted in the extrusion channel 111, wherein the wedge block 21 is located at the top of the transmission chamber 13, wherein a limiting groove 131 is arranged on the inner wall of the transmission chamber 13, wherein a floating frame 3 is slidably inserted in the limiting groove 131, wherein the floating frame 3 is slidably sleeved on the outer wall of the main shaft of the motor 2 A wedge block 2 36 is welded on the top outer wall of the floating frame 3, and the wedge block 2 36 is matched with the wedge block 1 21. A support rod 32 is welded on the outer wall of the floating frame 3, and a baffle 1 33 is welded on the outer wall of the bottom end of the support rod 32. A baffle 2 34 is welded on the outer wall of the baffle 1 33. An exhaust mechanism is provided in the housing 1. A spring 31 is welded between the outer wall of the floating frame 3 and the inner wall of the transmission chamber 13. The baffle 1 33 is slidably inserted in the passage between the extrusion channel 111 and the forming mold 113. At the transition point, the second baffle plate 34 is slidably inserted at the transition point between the extrusion channel 111 and the return glue channel 112, a discharge port 331 is opened on the outer wall of the baffle plate 1 33, a return port 341 is opened on the outer wall of the baffle plate 24, the spatial position of the discharge port 331 is higher than the spatial position of the return port 341, a stirring paddle 231 is rotatably inserted on the end wall of the stirring rod 23, a feed channel 12 is opened on the outer wall of the shell 1, and the feed channel 12 extends into the storage chamber 11.

[0028] In the initial state, under the action of the spring 31, the spring 31 pushes the floating frame 3 to stay on the top of the transmission chamber 13, so that the wedge block 2 36 is engaged with the wedge block 1 21. At the same time, the floating frame 3 pulls the baffle 1 33 and the baffle 2 34 upward through the support rod 32, so that the discharge port 331 on the baffle 1 33 is blocked, and the return port 341 on the baffle 2 34 is exposed, thereby opening the passage between the extrusion channel 111 and the return glue channel 112, and closing the passage between the extrusion channel 111 and the molding mold 113.

[0029] The above content is further elaborated: during operation, the melted material is input into the feed channel 12, and the material enters the storage chamber 11 along the feed channel 12. After the air conditioning pipe 9 is inserted into the molding mold 113, the motor 2 is started, and the motor 2 drives the wedge block 21, the screw 22 and the stirring rod 23 to rotate synchronously. Under the cooperation of the wedge block 21 and the wedge block 2 36, the floating frame 3 moves back and forth up and down, so that the floating frame 3 drives the baffle 1 33 and the baffle 2 34 to move back and forth up and down, so that the passage between the extrusion channel 111 and the molding mold 113 is opened and closed back and forth, and at the same time, the screw 22 continuously transports the material in the storage chamber 11 to the bottom of the extrusion channel 111, and cooperates with the up and down reciprocating movement of the baffle 1 33 to realize the control of the glue discharge speed, thereby controlling the uniformity of the glue discharge during molding. When it is necessary to increase or decrease the glue discharge amount, it is only necessary to control the speed of the motor 2 to increase or decrease, thereby avoiding the glue discharge speed. The unstable degree leads to the generation of bubbles, and when the baffle 1 33 closes the passage between the extrusion channel 111 and the molding die 113, the return port 341 on the baffle 2 34 opens the passage between the extrusion channel 111 and the return glue channel 112, so that the screw 22 pushes the material in the extrusion channel 111 into the return glue channel 112. Since the inner diameter of the extrusion channel 111 is larger than the inner diameter of the return glue channel 112, the extrusion force on the material is increased, and the bubbles entrained in the material are pushed upward. At the same time, the stirring rod 23 drives the stirring paddle 231 to stir the material, further promoting the floating of the bubbles, and finally releasing the gas in the bubbles into the storage chamber 11, avoiding the situation of bubbles entrained in the material during molding. When the material is squeezed into the molding die 113, it is molded into the outer protective layer 91, and then the air-conditioning pipe 9 is rolled up, so that the molten outer protective layer 91 adheres to the surface of the air-conditioning pipe 9 to complete the hot melt composite.

[0030] Specifically, the exhaust mechanism includes an airbag 4, the airbag 4 is bonded to the inner wall of the transmission chamber 13, the top outer wall of the airbag 4 is bonded to the outer wall of the floating frame 3, an air pipe 14 is welded to the top inner wall of the storage chamber 11, and an air pipe 2 15 is welded to the outer wall of the outer shell 1. The airbag 4 is located between the air pipe 14 and the air pipe 2 15, and the airbag 4 is connected with the air pipe 1 14 and the air pipe 2 15. A one-way air valve 141 is arranged between the air pipe 1 14 and the airbag 4. An inverted conical hole 142 is provided on the end wall of the air pipe 1 14, a conical plug 51 is slidably inserted in the conical hole 142, a floating block 5 is welded on the end wall of the conical plug 51, an exhaust port 151 is provided on the end wall of the air pipe 2 15, a sealing sleeve 35 is welded on the outer wall of the floating frame 3, the sealing sleeve 35 is slidably sleeved on the outer wall of the air pipe 2 15, and an air hole 351 is provided on the outer wall of the sealing sleeve 35.

[0031] The above content is further elaborated: when the material enters the storage chamber 11, the floating block 5 is subjected to the buoyancy of the material in a molten state, so that the conical plug 51 is inserted into the conical hole 142. At this time, the air pipe 14 is closed and no exhaust is performed. As the bubbles in the material are gradually squeezed upward, the bubbles gather in the upper layer of the material. The bubbles cannot provide sufficient buoyancy for the floating block 5, so that under the action of the floating block 5's own gravity, the floating block 5 pulls the conical plug 51 downward, thereby opening the air pipe 14. At the same time, the floating frame 3 reciprocates and compresses and stretches the air bag 4 during the up and down reciprocating movement. When the air bag 4 is stretched, the air hole 351 on the sealing sleeve 35 of the floating frame 3 is staggered with the exhaust port 151 on the air pipe 2 15, so that the gas in the storage chamber 11 is sucked into the air bag 4. When the air bag 4 is compressed, the floating frame 3 drives the air hole 351 on the sealing sleeve 35 to align with the exhaust port 151 on the air pipe 2 15, so that the gas is discharged through the air pipe 2 15.

[0032] A forming method of a pipe structure air conditioning insulation pipe, using a forming device of a double pipe structure air conditioning insulation pipe, comprises the following steps: S1, input the melted material into the feed channel 12, and the material enters the storage chamber 11 along the feed channel 12; S2, inserting the air conditioning pipe 9 into the molding die 113; S3, start the motor 2, and the motor 2 drives the wedge 21, the screw 22 and the stirring rod 23 to rotate synchronously; S4. When the glue output needs to be increased or decreased, it is only necessary to control the speed of motor 2 to increase or decrease; S5. After the material is squeezed into the molding die 113, it is molded into the outer protective layer 91. Then, the air conditioning pipe 9 is rolled up so that the molten outer protective layer 91 adheres to the surface of the air conditioning pipe 9, thereby completing the hot-melt bonding.

[0033] The working principle and use process of the present invention are as follows: during operation, the melted material is input into the feed channel 12, and the material enters the storage chamber 11 along the feed channel 12. After the air conditioning pipe 9 is inserted into the forming mold 113, the motor 2 is started, and the motor 2 drives the wedge block 1 21, the screw 22 and the stirring rod 23 to rotate synchronously. Under the cooperation of the wedge block 1 21 and the wedge block 2 36, the floating frame 3 moves back and forth up and down, so that the floating frame 3 drives the baffle 1 33 and the baffle 2 34 to move back and forth up and down, thereby making the passage between the extrusion channel 111 and the forming mold 113 open and close reciprocally. The screw 22 is closed, and at the same time, the screw 22 continuously transports the material in the storage chamber 11 to the bottom of the extrusion channel 111, and in cooperation with the up and down reciprocating movement of the baffle plate 33, the glue discharge speed is controlled, and then the uniformity of the glue discharge during molding is controlled. When it is necessary to increase or reduce the glue discharge amount, it is only necessary to control the speed of the motor 2 to increase or decrease, thereby avoiding the situation where the glue discharge speed is unstable and causes bubbles to be generated. In addition, when the baffle plate 33 closes the passage between the extrusion channel 111 and the molding mold 113, the return port 341 on the baffle plate 34 connects the extrusion channel 111 with the return glue passage. The passage between the channels 112 is opened, so that the screw 22 pushes the material in the extrusion channel 111 into the glue return channel 112. Since the inner diameter of the extrusion channel 111 is larger than the inner diameter of the glue return channel 112, the extrusion force on the material is increased, so that the bubbles entrained in the material are pushed upward. At the same time, the stirring rod 23 drives the stirring paddle 231 to stir the material, further promoting the bubbles to float, and finally the gas in the bubbles is released into the storage chamber 11, thereby avoiding the situation that bubbles are entrained in the material during molding. When the material is squeezed into the molding die 113 and molded into an outer The protective layer 91 is then rolled up on the air-conditioning pipe 9, so that the molten outer protective layer 91 adheres to the surface of the air-conditioning pipe 9 to complete the hot-melt compounding. At the same time, under the action of the exhaust mechanism, as the bubbles gather in the upper layer of the material, the bubbles cannot provide sufficient buoyancy for the float 5, so that under the action of the float 5's own gravity, the float 5 pulls the conical plug 51 downward, thereby opening the air pipe 14. When the airbag 4 is compressed, the floating frame 3 drives the air hole 351 on the sealing sleeve 35 to align with the exhaust port 151 on the air pipe 2 15, so that the gas is discharged through the air pipe 2 15.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
