Description

Technical Field

[0001] This utility model relates to the field of tent fabric production technology, specifically a tent fabric heat sealing machine. Background Technology

[0002] A tent is a complete shelter, usually covered with fabric, and comes in different shapes and sizes. To ensure the tent fabric is waterproof, airtight, and has high strength, a heat-sealing machine is used to heat-seal various fabrics together.

[0003] According to publication number CN222727619U, a hot press for processing composite fabrics includes a base, a worktable fixedly connected to the top of the base, a support rod fixedly connected to the top of the worktable, a pressure seat fixedly connected to the top of the support rod, a bracket fixedly connected to the top of the worktable and to the left of the pressure seat, and a hydraulic cylinder fixedly connected to the top of the bracket. The output end of the hydraulic cylinder is slidably connected to the bracket, and a connecting column is fixedly connected to the lower end of the output end of the hydraulic cylinder. This invention utilizes the design of the hydraulic cylinder to drive the pressure plate downwards to cooperate with the pressure seat in hot pressing the fabric. During the hot pressing process, the downward movement of the pressure plate also causes the protective cover to move downwards. The downward movement of the protective cover is limited by contact with the worktable, and the protective cover covers the outside of the pressure plate and pressure seat, protecting the hot pressing process and preventing burns caused by accidental contact by operators, thus improving the safety of the device.

[0004] The aforementioned protective structures can provide protection during hot pressing. However, since composite fabrics are generally quite long, the hot pressing efficiency of the fabric is reduced when using pressure plates and pressure seats to press the fabric locally, thus lowering the overall work efficiency.

[0023] This utility model provides a technical solution: such as Figures 1 to 5 As shown, in this embodiment, a tent fabric heat sealing machine includes a mounting box 1. A mounting frame 2 is fixedly connected to one side of the top of the mounting box 1. A bidirectional lead screw 3 is rotatably connected inside the mounting frame 2.

Screw sleeves 5 are symmetrically arranged on both sides of the surface of the bidirectional lead screw 3. Guide grooves 6 are symmetrically arranged on both sides of the mounting frame 2. A movable seat 7 is slidably connected inside the guide groove 6. An upper heating roller 8 is rotatably connected inside the movable seat 7. A rotating seat 9 is fixedly connected to the top of the movable seat 7. A rotating plate 10 is rotatably connected between the rotating seat 9 and the screw sleeves 5.

[0024] When the motor 4 is started, its output shaft drives the bidirectional lead screw 3 to rotate. The screw sleeve 5 rotates on the surface of the bidirectional lead screw 3, and the rotating plate 10 rotates accordingly, pushing the moving seat 7 and the upper heating roller 8 to move down. The upper heating roller 8, the lower heating roller 12 and the fabric are in contact, thereby heating the fabric and conveying it at the same time to ensure the overall efficiency of the fabric heat sealing.

[0025] A fixed base 11 is fixedly connected to the bottom of the inner wall of the guide groove 6. A lower heating roller 12 is rotatably connected inside the fixed base 11. An exhaust valve 13 is provided on one side of both the lower heating roller 12 and the upper heating roller 8.

[0026] The installation box 1 is equipped with a water storage tank 14, and a heating pipe 15 is installed inside the water storage tank 14. A connecting pipe 16 is fixedly connected to one side of the water storage tank 14, and the connecting pipe 16 is fixedly connected to the upper heating roller 8 and the lower heating roller 12.

[0027] Water is supplied to the water tank 14, and the heating tube 15 is energized to heat the water, turning it into steam that carries heat. This steam then enters the upper heating roller 8 and the lower heating roller 12 through the connecting pipe 16, thereby preheating the inner cavity. Temperature sensors are installed on the upper heating roller 8 and the lower heating roller 12 to detect the surface temperature and keep it within a preset range. Multiple slots can be provided on the upper heating roller 8 and the lower heating roller 12 to allow the steam to come into contact with the fabric, maintaining a certain level of humidity while heating the fabric to prevent damage during pressing. An exhaust valve 13 is provided on one side of the upper heating roller 8 and the lower heating roller 12, which works in conjunction with an internal pressure sensor to control the internal pressure.

[0028] A bracket 17 is fixedly connected to the top of the mounting box 1, and a conveyor belt 18 is installed inside the bracket 17.

[0029] A pressing frame 19 is fixedly connected to the top of the mounting box 1. A cylinder 20 is fixedly connected to the top of the pressing frame 19. A connecting frame 21 is fixedly connected to the bottom of the cylinder 20. A pressing roller 22 is rotatably connected inside the connecting frame 21. Guide rods 23 are symmetrically arranged on both sides of the top of the connecting frame 21. The guide rods 23 and the pressing frame 19 are slidably connected.

[0030] Threaded sleeves 24 are symmetrically arranged on both sides of the pressing frame 19. An adjusting screw 25 is connected to the inside of the threaded sleeve 24, and a handle 26 is fixedly connected to one end of the adjusting screw 25.

[0031] Two stabilizing rods 27 are symmetrically arranged on both sides of the pressing frame 19. One end of the stabilizing rod 27 is fixedly connected to the limiting seat 28, and the limiting seat 28 is rotatably connected to the adjusting screw 25.

[0032] Rotate the handle 26 to make the adjusting screw 25 rotate inside the threaded sleeve 24. The adjusting screw 25 pushes the limiting seat 28 to one side, and the stabilizing rod 27 slides inside the pressing frame 19. After rotating a certain number of times, the limiting seat 28 contacts both sides of the fabric, thereby guiding and limiting the movement of the fabric, avoiding displacement during pressing, and improving the accuracy of fabric heat sealing.

[0033] This utility model provides a heat-sealing machine for tent fabric, the specific working principle of which is as follows:

[0034] In use, water is supplied to the water tank 14, and the heating tube 15 is energized to heat the water, turning it into steam that carries heat. This steam then enters the upper heating roller 8 and the lower heating roller 12 through the connecting pipe 16 for preheating. The fabric is placed between the upper heating roller 8 and the lower heating roller 12, and the conveyor feeds the fabric. The motor 4 is started, and its output shaft drives the bidirectional lead screw 3 to rotate. The screw sleeve 5 rotates on the surface of the bidirectional lead screw 3, and the rotating plate 10 rotates accordingly, pushing the moving seat 7 and the upper heating roller 8 downward. The upper heating roller 8, the lower heating roller 12, and the fabric come into contact, thus heating the fabric instantly. The fabric moves into the pressing frame 19, and the cylinder 20 is started. Its output rod pushes the connecting frame 21 and the pressing roller 22 downward, bringing the fabric into contact with the conveyor belt 18 and the pressing roller 22. This allows the fabric to be conveyed and pressed simultaneously, enabling continuous production of tent fabric.
