Detailed Description

The vacuum shaping water tank of the plastic pipe is composed of a shaper 1, a water tank body 2 and a supporting roller 3 (see the attached figure 1 in the specification).

A plurality of cooling chambers 5 are partitioned in the water tank body 2 through uniformly distributed partition plates 4 (see the attached figure 1 of the specification); the purpose of dividing the tank body 2 into a plurality of cooling chambers 5 is: so that the shaping water tank is cooled gradually in a segmented manner through the cooling chamber 5, and the problem of plastic pipe scrapping caused by stress concentration when the plastic pipe is cooled too fast is prevented.

The middle part of the cooling chamber 5 is provided with a supporting roller 3 through a bracket; the bottom of the cooling cavity 5 at one side of the supporting roller 3 is connected with a water outlet pipe 6; the upper part of the cooling chamber 5 at the other side of the supporting roller 3 is connected with a water inlet pipe 7; the water outlet pipe 6 and the water inlet pipe 7 are communicated with an external cooling water system, and the external cooling water system can enable the cooling cavity 5 to keep cooling water with a certain liquid level through the water outlet pipe 6 and the water inlet pipe 7 and can achieve the purpose of controlling the temperature of cooling water in the cooling cavity 5 in a mode of controlling the flow rate of the cooling water during working.

The bottom of the cooling chamber 5 is provided with a vacuum generating pipe 8; the lower end of the vacuum generating pipe 8 is communicated with an external vacuum control system; the external vacuum control system can pump out the air in the cooling chamber 5 through the vacuum generating pipe 8, so as to achieve the purpose of vacuum pumping.

The upper end of the vacuum generating tube 8 extends to the upper part of the cooling chamber 5; the purpose of this arrangement of the vacuum generating channels 8 is: so that the upper ends of the vacuum generating tubes 8 are located above the level of the cooling water in the cooling chamber 5 to prevent the problem of "leakage" of the cooling water through the vacuum generating tubes 8.

The middle part of one end of the water tank body 2 is provided with a calibrator 1 by pressing through a hinged locking compression ring 9 (refer to the attached figure 1 in the specification); one side of the locking compression ring 9 is hinged with the end of the water tank body 2; the other side of the locking compression ring 9 is provided with a locking fork opening 11; the end of the water tank body 2 is hinged with a locking bolt 12; the nut of the locking bolt 12 is intermittently locked with the locking fork 11 (see the attached figure 3 in the specification). The purpose of so setting the locking collar 9 is: so that calibrator 1 can be through locking clamping ring 9 and locking bolt 12 with calibrator 1 quick pressure equipment at the end of water tank body 2 when the assembly to avoid calibrator 1 to have the loaded down with trivial details problem of assembly when installing at water tank body 2 end through the bolt, reached quick installation and changed calibrator 1's purpose.

A penetrating guide hole 10 (refer to the attached figure 1 in the specification) is respectively arranged on the partition plate 4 at one side of the calibrator 1 and the other end of the water tank body 2; the calibrator 1, the through guide hole 10 and the support roller 3 are in the same line. Because this design water tank during operation moulds the pipe and passes water tank body 2 through calibrator 1, run through guide hole 10 and supporting roller 3 and carry out the refrigerated, consequently only with it setting on same straight line, just can ensure to mould the pipe and pass through smoothly, carries out the cooling design.

The calibrator 1 is composed of a shower plate 13, a mounting plate 14, a support rod 15, and a guide ring plate 16 (see fig. 4 in the specification).

A spray plate 13 is fixedly arranged on one side of the assembly plate 14 through bolts (see the description and the attached figure 4); the outer diameter of the spray plate 13 is smaller than that of the assembly plate 14; the inner diameter of the locking compression ring 9 is consistent with the outer diameter of the spray plate 13; the purpose of thus setting the outer diameters of the shower plate 13 and the fitting plate 14 is to: after the locking compression ring 9 can penetrate through the spraying plate 13 in the working process, the calibrator 1 is tightly pressed and fixedly arranged at one end of the water tank body 2 in a manner of pressing the assembling plate 14.

A plurality of positioning pins 17 are uniformly distributed on the inner side surface of the assembling plate 14; the positioning pin 17 is in plug-in connection with a positioning hole at the end of the water tank body 2; so set up the locating pin 17 after, locating pin 17 can carry out spacingly to calibrator 1 under the cooperation of locating hole, and then has reached the purpose of assembling calibrator 1 smoothly.

Guide holes 20 are respectively arranged in the middle parts of the spraying plate 13 and the assembling plate 14 (see the description and the attached figure 4); a plurality of support rods 15 are fixedly arranged on the other side of the assembling plate 14 in a circular ring shape; the tail end of the supporting rod 15 is connected with a compression nut 19 through threads; a plurality of guide ring plates 16 are attached to the support rod 15 at intervals by spacer collars 18 and compression nuts 19 provided at intervals. The inner hole of the guide ring plate 16 is opposite to the guide hole 20 (see the description and the attached figure 4); the guide ring plate 16 and the guide hole 20 are provided so as to: so that the plastic pipe can enter the water tank body 2 through the guide hole 20 and the inner hole of the guide ring plate 16 for cooling and shaping during operation.

The spacing between the guide ring plates 16 increases gradually from right to left (see the description of fig. 4). The purpose of so setting is: when the shaping water tank works, the plastic pipe sequentially passes through the guide holes 20 of the guide ring plates 16 from right to left to shape the plastic pipe; in the process, the plastic pipe has the characteristic of gradually cooling and hardening in the calibrator 1; therefore, the plasticity of the plastic pipe is stronger when the plastic pipe just enters the shaping device 1, so that when the distance between the shaping plates 2 on the right side is small, the density is larger, and more shaping plates 2 can carry out shaping limit on the plastic pipe; therefore, the problem of deformation caused by lack of constraint when the plastic pipe just enters the shaping device can be avoided.

The inner side of the spray plate 13 is provided with a spray boss 21 (see the attached figure 7 in the specification); the outer side of the assembly plate 14 is provided with an assembly counter bore 22 (see the description and the attached figure 4); the spray boss 21 extends to the interior of the assembly counterbore 22 and is in fit connection therewith (see the description of figure 4).

A buffer ring groove 23 is arranged on the spray plate 13 around the assembly counter bore 22 (see the attached figure 8 in the specification); a plurality of water through holes 24 are uniformly distributed on the buffer ring groove 23; the water through hole 24 is communicated with an external cooling water source; a plurality of diversion trenches 25 are arranged on the end surface of the spraying boss 21 in a divergent manner (see the attached figure 8 in the specification); the buffer ring groove 23 communicates with the guide hole 20 through the guide groove 25. Thus, when the water through holes 24 are communicated with an external cooling water source, cooling water can enter the buffer ring groove 23 through the water through holes 24; the cooling water entering the buffer ring groove 23 can be uniformly sprayed into the guide hole 20 through the guide groove 25, so that the aim of spraying and cooling from the inside of the guide hole 20 through the plastic pipe is fulfilled. The inner diameter of the guide hole 20 is larger than the outer diameter of the plastic pipe, so that the problem that the plastic pipe and the guide hole 20 are abraded due to scratch can be avoided.

In addition mould in this application and manage before getting into water tank body 2, can accept the cooling that sprays of calibrator 1, and then reach the solidification and mould a tub surface, avoided moulding the inside and taking place the friction of pipe and water tank body 2 when, damage the problem on surface.

In the process of spraying, cooling and cooling the entering plastic pipe by the shaper 1; the sprayed water can seal the gap between the plastic pipe and the calibrator 1 by the principle of water seal; thereby avoiding the problem of low product quality caused by the external air entering the water tank body 2 from the gap.

When the vacuum shaping water tank of the plastic pipe works, the plastic pipe can continuously penetrate through the water tank body 2 for cooling through the shaping device 1, the through guide hole 10 and the supporting roller 3. In the process, the water outlet pipe 6 and the water inlet pipe 7 in each cooling chamber 5 can enable the cooling water in the cooling chamber 5 with a certain liquid level to immerse the plastic pipe in a mode of continuously supplementing and discharging water so as to achieve the purpose of uniformly cooling the plastic pipe.

In the process of cooling the plastic pipe, people can control the temperature of cooling water in the cooling chambers 5 by controlling the flow rate of the cooling water, so that the temperature of the cooling water in each cooling chamber 5 is different. Therefore, the plastic pipe is gradually cooled in sections through the cooling chambers 5, and the problem of plastic pipe scrapping caused by stress concentration when the plastic pipe is cooled too fast is solved.

Meanwhile, the external vacuum control system can pump out air above the liquid level of the cooling water in the cooling chamber 5 through the vacuum generating pipe 8, so that the purpose of enabling the cooling chamber 5 to be in a negative pressure state is achieved. Thereby ensured that mould the inside pressure of pipe and be greater than external pressure, and then made the pipe can keep being the circular state and stereotype, avoided external pressure to be greater than the problem that the internal pressure takes place to flatten and mould the pipe.

The vacuum shaping water tank of the plastic pipe has compact structure and ingenious design; the plastic pipe cooling and shaping work can be completed in an immersion mode, so that the problem that the rejection rate is high due to uneven cooling of the plastic pipe easily occurs when the existing shaping water tank adopts spray cooling to complete the shaping work of the plastic pipe is solved; in addition, the shaper can cool and seal the plastic pipe in a spraying mode before contacting the plastic pipe; therefore, the problem that the surface of the plastic pipe is easy to damage when the plastic pipe directly enters the existing shaping water tank is avoided, and the problem that the product quality is low because air easily enters from the gap between the plastic pipe and the shaping water tank is solved; thereby meeting the production and use requirements of enterprises.
