Description

Technical Field

[0001] The invention relates to the field of temperature-controlled water tanks, and in particular to a temperature-controlled water tank. Background Art

[0002] Warm water plays a key role in cooling and shaping the PVC foam board during the molding process. The PVC melt extruded by the extruder needs to be quickly cooled to fix its shape and structure. The warm water cooling system can ensure that the board is cooled quickly after leaving the mold to avoid the surface quality degradation caused by the melt being exposed to the air for a long time.

[0003] In traditional temperature control methods, the lack of water fluidity inside the water tank often leads to uneven water temperature distribution. This uneven water temperature condition will directly affect the molding quality of PVC foam board, causing shrinkage marks and uneven thickness on the board surface.

[0004] Existing heating methods often use a single heating tube for heating, which has low heating efficiency. This not only prolongs the heating time and increases energy consumption, but may also cause temperature stress inside the plate due to uneven heating, affecting the overall performance of the product. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, the purpose of the present invention is to provide a temperature-controlled water tank, which solves the following technical problems: how to achieve accurate and uniform control of water temperature, and how to improve the heating efficiency.

[0007] Preferably, a notch is provided on one side of the annular bracket, the notch is connected to the annular groove, a toothed ring is provided on the inner wall at the bottom of the rotating ring, a rotating shaft is rotatably connected inside the box, a driving gear is fixedly connected to the top of the rotating shaft, and one side of the driving gear is embedded in the notch and meshed with the toothed ring.

[0008] Preferably, a motor is installed inside the base frame, and the output end of the motor is fixedly connected to the end corresponding to the rotating shaft. The motor is the power source of the mechanical transmission system of the entire temperature-controlled water tank. It drives the rotating shaft to rotate, and then drives the rotating ring to rotate through the engagement of the driving gear and the toothed ring.

[0009] Preferably, retaining rings are symmetrically provided on the outer side of the cylindrical seat, which can prevent the rotating drum from axially moving during rotation, thereby ensuring a stable connection between the rotating drum and the cylindrical seat. The top ends of the short rods are arranged in an arc shape. The arc-shaped design can reduce the friction resistance between the short rods and the inner wall of the spiral groove, thereby improving the sliding efficiency of the short rods in the spiral groove, and can also prevent the short rods from damaging the inner wall of the spiral groove during sliding, thereby extending the service life of the spiral groove.

[0010] Preferably, a heating pipe is installed inside the box, and support bars are symmetrically fixedly connected inside the box. The support bars are sleeved on the outside of the heating pipe. The heating pipe heats the water in the water tank to a set temperature by electric heating, thereby meeting the temperature conditions required for the molding of the PVC foam board.

[0011] Preferably, an annular slide bar is fixedly connected to the outside of the rotating ring, an annular slide groove is opened inside the annular bracket on the outside of the annular groove, and the annular slide bar is slidably connected inside the annular slide groove. The sliding of the annular slide bar in the annular slide groove can ensure the stability of the rotating ring during rotation.

[0012] Preferably, a partition frame is fixedly connected inside the box body, a driving shaft is rotatably connected between the partition frame and the bottom of the box body, a driven gear is fixedly connected to the outside of the driving shaft, the driven gear is meshingly connected to the driving gear, a rotating rod is rotatably connected above the partition frame, a swing plate is fixedly connected to one side of the rotating rod, and a linkage mechanism is installed between the driving shaft and the rotating rod.

[0013] The linkage mechanism includes a connecting piece, a side plate and a cross bar. The top end of the driving shaft passes through the partition frame and is fixedly connected with the connecting piece at the end. The outer side of the rotating rod is symmetrically fixedly connected with the side plates, and the cross bar is fixedly connected between the side plates.

[0014] The linkage mechanism also includes a sleeve and a slide rod. The outer side of the cross bar is slidably connected with the sleeve, the bottom of the sleeve is fixedly connected with the slide rod, and the bottom end of the slide rod is slidably inserted into the interior of the connecting piece.

[0015] Compared with the prior art, the advantages of the present invention are as follows: 1. The present invention realizes the continuous annular flow of water inside the water tank through the linkage mechanism of the rotating ring, the rotating drum and the fan blades. This flow mode greatly improves the uniformity of the water temperature and ensures that the PVC foam board can obtain stable and consistent temperature conditions during the molding process, thereby improving the quality of the product.

[0016] 2. The present invention not only promotes the circulation of water through the stirring action of the fan blades, but also helps to improve the heating efficiency of the heating tube. The continuous flow of water enables the heat released by the heating tube to be transferred to the water in the entire water tank more quickly, shortening the heating time and reducing energy consumption.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] The temperature-controlled water tank comprises a tank body 1; like Figures 1 to 9As shown, an annular bracket 3 is fixedly connected inside the box body 1, an annular groove 4 is provided on the top of the annular bracket 3, a rotating ring 5 is rotatably connected inside the annular groove 4, a cylindrical seat 6 is provided in an annular array outside the annular bracket 3, an arc groove 7 is provided on the top of the cylindrical seat 6, the arc groove 7 is connected to the annular groove 4, a rotating drum 8 is rotatably connected to the outside of the cylindrical seat 6, and the inner wall of the rotating drum 8 is divided into spiral grooves 9 in an annular array with the axis as the center, a short rod 10 is provided in an annular array on the top of the rotating ring 5, and the top ends of several short rods 10 located inside the rotating drum 8 are slidably inserted in the corresponding spiral grooves 9 in sequence, and a fan blade 11 is provided in an annular array outside the rotating drum 8; As the rotating ring 5 rotates, the short rods 10 in the circular array on its top enter the interior of the rotating drum 8 outside the cylindrical seat 6 in turn, and the top ends of the short rods 10 slide in the spiral grooves 9, thereby guiding the rotating drum 8 to rotate. The rotation of the rotating drum 8 drives the fan blades 11 in the circular array on the outside to rotate. The stirring action of the fan blades 11 makes the water inside the water tank form a circular flow. This flow mode not only improves the uniformity of the water temperature, but also helps to improve the heating efficiency.

[0029] like Figures 1 to 9 As shown, a notch 12 is provided on one side of the annular bracket 3, the notch 12 is connected to the annular groove 4, a toothed ring 13 is provided on the inner wall of the bottom of the rotating ring 5, a rotating shaft 14 is rotatably connected inside the box body 1, a driving gear 15 is fixedly connected to the top of the rotating shaft 14, and one side of the driving gear 15 is embedded in the notch 12 and meshed with the toothed ring 13; The rotating shaft 14 drives the driving gear 15 at the top to rotate, and is embedded in the notch 12 on one side of the annular bracket 3 to form a meshing connection with the toothed ring 13 on the bottom inner wall of the rotating ring 5. Driven by the driving gear 15, the rotating ring 5 rotates in the annular groove 4 inside the annular bracket 3.

[0030] like Figures 1 to 9 As shown, a motor 16 is installed inside the base frame 2, and the output end of the motor 16 is fixedly connected to the corresponding end of the rotating shaft 14. The motor 16 drives the rotating shaft 14 to rotate, and then drives the rotating ring 5 to rotate through the engagement of the driving gear 15 and the toothed ring 13.

[0031] like Figures 1 to 9 As shown, a retaining ring 17 is symmetrically provided on the outer side of the cylindrical seat 6, and the retaining ring 17 can prevent the rotating drum 8 from axial movement during rotation, thereby ensuring a stable connection between the rotating drum 8 and the cylindrical seat 6. The top ends of the short rods 10 are arranged in an arc shape, which can reduce the friction resistance between the inner wall of the spiral groove 9, thereby improving the sliding efficiency of the short rods 10 in the spiral groove 9.

[0032] like Figures 1 to 9As shown, a heating tube 18 is installed inside the box body 1, and the water in the water tank is heated to a set temperature by electric heating. This step is the basis of temperature control, which ensures that the water temperature can meet the temperature conditions required for the molding of the PVC foam board. The heating of the heating tube 18 and the stirring of the fan blades 11 can evenly increase the water temperature in the temperature-controlled water tank to a set value. When the water temperature reaches the set value, the heating tube 18 stops heating through the temperature control system. Support bars 21 are symmetrically fixedly connected inside the box body 1. The support bars 21 are sleeved on the outside of the heating tube 18. The support bars 21 can make the heating tube 18 more firmly installed in the box body 1.

[0033] like Figures 1 to 9 As shown, an annular slide bar 19 is fixedly connected to the outside of the rotating ring 5, and an annular slide groove 20 is opened inside the annular bracket 3 on the outside of the annular groove 4. The annular slide bar 19 is slidably connected inside the annular slide groove 20. The cooperation between the annular slide bar 19 and the annular slide groove 20 can provide a guiding effect for the rotation of the rotating ring 5, thereby ensuring the accuracy of the rotation.

[0034] like Figures 1 to 9 As shown, a partition frame 22 is fixedly connected inside the box body 1, a driving shaft 23 is rotatably connected between the partition frame 22 and the bottom of the box body 1, a driven gear 24 is fixedly connected to the outside of the driving shaft 23, and the driven gear 24 is meshed and connected with the driving gear 15, a rotating rod 25 is rotatably connected above the partition frame 22, a swing plate 26 is fixedly connected to one side of the rotating rod 25, and a linkage mechanism 27 is installed between the driving shaft 23 and the rotating rod 25; By driving the gear 15 to rotate, the driven gear 24 and the drive shaft 23 are driven to rotate, and then the rotating rod 25 drives the swing plate 26 to swing back and forth through the linkage mechanism 27, so as to promote and guide the water flow to be evenly distributed inside the water tank, so as to keep the water flow evenly flowing inside the entire water tank, thereby improving the uniformity and efficiency of temperature control.

[0035] like Figures 1 to 9 As shown, the linkage mechanism 27 includes a connecting piece 28, a side plate 29 and a cross bar 30. The top end of the driving shaft 23 passes through the partition frame 22 and is fixedly connected to the connecting piece 28 at the end. The side plates 29 are symmetrically fixedly connected to the outside of the rotating rod 25. The cross bar 30 is fixedly connected between the side plates 29. The linkage mechanism 27 also includes a sleeve 31 and a slide bar 32. The sleeve 31 is slidably connected to the outside of the cross bar 30. The slide bar 32 is fixedly connected to the bottom of the sleeve 31. The bottom end of the slide bar 32 is slidably inserted into the inside of the connecting piece 28. When the drive shaft 23 rotates, the connecting piece 28 rotates accordingly and moves in a circle through the slide bar 32. During the movement, the sleeve 31 is used to pull the cross bar 30, so that the cross bar 30 drives the rotating rod 25 to rotate reciprocatingly through the side plate 29, thereby driving the swing plate 26 to swing back and forth. In the process of the sleeve 31 pulling the cross bar 30, it will slide on the outside of the cross bar 30 as the position of the slide bar 32 changes.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
