Description

Technical Field

[0001] This utility model relates to the field of packing strap production technology, specifically to a constant temperature water bath heating tank for stretching packing straps. Background Technology

[0002] Packing straps, also known as strapping, are mainly made of polyethylene or polypropylene resin. They are produced by heating and melting the resin, then extruding and stretching it through a mold. After the packing straps are formed, their surface needs to be embossed to increase their surface friction. Finally, heating and cooling are used to help them set their shape and eliminate internal stress, giving them stable mechanical properties.

[0003] In existing technologies, a problem exists when stretching packing straps: impurities in the water, especially calcium and magnesium ion precipitates, easily adhere to the surface of the packing straps. Specifically, during the stretching process, these calcium and magnesium ion precipitates continuously accumulate and adhere to the surface of the packing straps, eventually causing the surface to become rough and thus reducing the overall quality of the packing straps. To address this, we propose a constant temperature water bath heating tank for stretching packing straps. Summary of the Invention

[0004] The purpose of this invention is to provide a constant temperature water bath heating tank for stretching packing straps, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature water bath heating tank for stretching packing straps, comprising a heating chamber and a temperature control device. A heating chamber is provided in the middle of the upper end of the heating chamber. A partition inclined plate and a heating assembly are fixedly installed inside the heating chamber. The heating assembly is located on the upper part of the partition inclined plate. A liquid discharge assembly is provided on the lower side of the middle right end of the heating chamber. A filter screen moving mechanism is provided on the heating chamber. The filter screen moving mechanism includes a filter screen body and two side limiting components for the packing straps. The two side limiting components for the packing straps are used to limit the upper ends of the packing straps on both sides within the heating chamber. The filter screen moving mechanism is used to move the filter screen body at a certain height and allows for convenient disassembly of the filter screen body.

[0006] Preferably, the filter screen moving mechanism further includes multiple symmetrically arranged L-shaped plates. The vertical end of each L-shaped plate is fixedly installed on the outer wall of the heating box near the heating box body. An electric push rod is fixedly installed at the middle of the lower end of the horizontal section of each L-shaped plate. A moving plate is fixedly installed at the ends of the multiple electric push rods. A placement groove is opened in the middle of the upper end of the moving plate. Multiple symmetrically arranged inserts are fixedly installed at the upper end of the moving plate. An L-shaped insert plate is slidably connected to the outer wall of each insert. The filter screen body is fixedly installed between the multiple L-shaped inserts.

[0007] Preferably, the packing strap side limiting components include two symmetrically arranged side plates. The lower end of each side plate is fixedly installed on the upper end of a movable plate. The two side plates are close to each other at one end and are rotatably connected to a follower shaft through a bearing. A packing strap limiting wheel is fixedly installed in the middle of the outer end of the follower shaft. Limiting plates are fixedly installed at both the front and rear ends of the packing strap limiting wheel.

[0008] Preferably, the liquid discharge assembly includes a liquid discharge pipe, one end of which is fixedly connected to the heating chamber, and an electromagnetic valve is provided at the outer end of the liquid discharge pipe.

[0009] Preferably, the heating assembly includes a mounting frame, the outer wall of which is fixedly mounted to the inner wall of the heating chamber, and a plurality of heating wires evenly distributed are fixedly mounted on the inner wall of the mounting frame.

[0010] Preferably, each of the insertion posts is disposed on the outside of the placement groove, and the outer wall of the filter screen body is slidably connected to the inner wall of the placement groove.

[0011] Preferably, a temperature control device is fixedly installed at the center of the front end of the heating box, and the temperature control device is electrically connected to the heating wire.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through a filter screen moving mechanism, firstly supplies power and controls the heating component via a temperature control device. The heating component heats the water in the heating chamber and maintains a constant temperature. Impurities in the water float to the surface. Then, multiple electric push rods are simultaneously powered and controlled via an external power supply and controller. The telescopic ends of these electric push rods directly drive the moving plate upwards. This moving plate then directly drives the insert post, L-shaped insert plate, and filter screen body upwards. During this process... The filter body moves within the heating chamber, filtering impurities from the water. When it reaches the top, each L-shaped insert can be removed from the post, causing it to move upwards. A new filter body can then be installed. This upward movement of the filter body within the heating chamber effectively filters impurities and allows for easy disassembly and replacement, reducing impurity levels and improving the quality of the packing strap.

[0014] 2. This utility model can achieve the overall limiting effect of the strapping by using the limiting components on both sides of the strapping when the strapping is stretched. At this time, the lower end of the strapping can be set under the two strapping limiting wheels, and the two sides of the strapping extend from both sides of the heating box.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a constant temperature water bath heating tank for stretching packing straps, including a heating chamber 1 and a temperature control device 4. A heating chamber 3 is provided in the middle of the upper end of the heating chamber 1. A partition inclined plate 5 and a heating component 6 are fixedly installed inside the heating chamber 3. The heating component 6 is located on the upper part of the partition inclined plate 5. A liquid discharge component 2 is provided on the lower side of the middle of the right end of the heating chamber 1. A filter screen moving mechanism 7 is provided on the heating chamber 1. The filter screen moving mechanism 7 includes a filter screen body 77 and packing strap side limiting components 78. The packing strap side limiting components 78 are used to limit the upper ends of the packing straps on both sides in the heating chamber 3. The filter screen moving mechanism 7 is used to move the filter screen body 77 at a certain height and can easily disassemble the filter screen body 77.

[0022] In this embodiment, the filter screen moving mechanism 7 also includes a plurality of symmetrically arranged L-shaped plates 71. The vertical end of each L-shaped plate 71 is fixedly installed on the outer wall of the heating box 1 near the heating box 1. An electric push rod 72 is fixedly installed at the middle of the lower end of the horizontal section of each L-shaped plate 71. The ends of the telescopic rods of the plurality of electric push rods 72 are fixedly installed together with a moving plate 73. A placement groove 74 is opened in the middle of the upper end of the moving plate 73. A plurality of symmetrically arranged inserts 75 are fixedly installed on the upper end of the moving plate 73. An L-shaped insert plate 76 is slidably connected to the outer wall of each insert plate 75. The filter screen body 77 is fixedly installed together among the plurality of L-shaped inserts 76.

[0023] Specifically, the filter moving mechanism 7 first supplies power and controls the heating component 6 via the temperature control 4. The heating component 6 then heats the water in the heating chamber 3 and maintains a constant temperature. Impurities in the water then float to the surface. Simultaneously, multiple electric push rods 72 are powered and controlled via an external power supply and controller. The extension rod ends of the electric push rods 72 directly drive the moving plate 73 upwards. The moving plate 73 then directly drives the insertion post 75, the L-shaped insertion plate 76, and the filter body 77 upwards. During this process, the filter... The filter body 77 moves within the heating chamber 3, filtering impurities in the water. When it reaches the top, each L-shaped insert 76 can be removed from the insert post 75. The L-shaped insert 76 then moves the filter body 77 upwards. A new filter body 77 can then be installed. This upward movement of the filter body 77 within the heating chamber 3 effectively filters impurities in the water and allows for easy disassembly and replacement, reducing the impurity content within the heating chamber 3 and improving the quality of the packing tape.

[0024] In this embodiment, the two side limiting components 78 of the packing strap include two symmetrically arranged side plates 781. The lower end of each side plate 781 is fixedly installed on the upper end of the movable plate 73. The two side plates 781 are close to each other at one end and are rotatably connected to a follower shaft 782 through a bearing. A packing strap limiting wheel 783 is fixedly installed in the middle of the outer end of the follower shaft 782. Limiting plates 784 are fixedly installed at both the front and rear ends of the packing strap limiting wheel 783.

[0025] Specifically, the strapping strap can be stretched by using the limiting components 78 on both sides. At this time, the lower end of the strapping strap can be set under the two strapping strap limiting wheels 783, and the two sides of the strapping strap can extend from both sides of the heating box 1, thus completing the overall limiting function of the strapping strap.

[0026] In this embodiment, the liquid discharge assembly 2 includes a liquid discharge pipe 21. One end of the liquid discharge pipe 21 near the heating chamber 1 is fixedly connected to the heating chamber 1, and a solenoid valve 22 is provided at the outer end of the liquid discharge pipe 21.

[0027] Specifically, the draining assembly 2 can be used to drain water that has been used for a long time in the heating chamber 3.

[0028] In this embodiment, the heating component 6 includes a mounting frame 61, the outer wall of which is fixedly mounted on the inner wall of the heating chamber 3, and a plurality of uniformly distributed heating wires 62 are fixedly mounted on the inner wall of the mounting frame 61.

[0029] Specifically, the heating component 6 can be used to heat the water in the heating chamber 3.

[0030] In this embodiment, each insertion post 75 is disposed on the outside of the placement groove 74, and the outer wall of the filter body 77 is slidably connected to the inner wall of the placement groove 74.

[0031] Specifically, ensure that the filter body 77 does not interfere with the moving plate 73 during installation.

[0032] In this embodiment, a temperature control device 4 is fixedly installed at the middle of the front end of the heating box 1, and the temperature control device 4 is electrically connected to the heating wire 62.

[0033] Specifically, the temperature control device 4 can be used to control the temperature of the heating component 6.

[0034] Working Principle: First, the heating component 6 is powered and controlled via the temperature control unit 4. The heating component 6 heats the water in the heating chamber 3 and maintains a constant temperature. Impurities in the water float to the surface. Simultaneously, multiple electric push rods 72 are powered and controlled via an external power supply and controller. The extension rod ends of the electric push rods 72 directly drive the moving plate 73 upwards. The moving plate 73 then directly drives the insertion post 75, the L-shaped insertion plate 76, and the filter screen body 77 upwards. During this process, the filter screen body 77 circulates within the heating chamber 3, filtering impurities from the water. When the filter body 77 moves to the top, each L-shaped insert 76 can be removed from the insert post 75. At this time, the L-shaped insert 76 directly drives the filter body 77 to move upward. Then, a new filter body 77 can be installed. Next, the multiple electric push rods 72 are simultaneously powered and controlled by the external power supply and external controller. At this time, the telescopic rod ends of the electric push rods 72 directly drive the moving plate 73, insert post 75, L-shaped insert 76, filter body 77, and the limiting components 78 on both sides of the strapping to move downward. When stretching the strapping, the lower end of the strapping can be set under the two strapping limiting wheels 783. The two sides of the strapping extend from both sides of the heating box 1, which can complete the overall limiting function of the strapping.
