Description

Technical Field

[0001] This utility model relates to the technical field of heat shrink film processing equipment, specifically a heat shrink film heat shrink wrapping heating equipment. Background Technology

[0002] Heat shrink film, after being heated and shrinking, can tightly wrap the product, forming a tight protective film with good moisture-proof, dust-proof, and abrasion-proof functions. It can effectively protect the product from damage during transportation and storage. Traditional heat shrink film is heated by manually holding a hot air blower to heat the surface of the heat shrink film. However, manual heating can only heat the surface of the product locally, resulting in uneven heating of the heat shrink film, affecting the shrinkage effect of the heat shrink film, reducing packaging quality, and heating in an open environment. The heating effect of the hot air blower is not good, and it needs to be used for a long time, which can easily lead to excessive wear and tear on the hot air blower and increase costs. To solve the above problems, a heat shrink film heat shrink wrapping heating device is needed.

[0003] Existing heat shrink film coating heating equipment suffers from uneven heating of the heat shrink film covering the product surface and insufficient heat utilization. This leads to prolonged continuous use of the hot air blower, increasing wear and tear, and fails to prevent the product from shaking and falling during heating, thus affecting the heating effect. Therefore, there is an urgent need for a heat shrink film coating heating equipment. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a heat shrink film heating device to solve the problems of uneven heating of the heat shrink film covering the product surface and insufficient heat utilization when using existing heat shrink film heating devices, which leads to long-term continuous use of the hot air blower, increased wear and tear, and inability to prevent the product from shaking and falling during the heating process, thus affecting the heating effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat shrink film heat shrink wrapping heating device, comprising a heating machine body, a hot air blower installed on the outer wall of the heating machine body, a hot air outlet installed on the outer wall of the hot air blower, a limiting frame installed on the outer wall of the heating machine body, a sliding groove opened on the inner wall of the limiting frame, a cover plate installed on the inner wall of the sliding groove, a pull rod installed on the outer wall of the cover plate, and a return spring installed on the outer wall of the pull rod.

[0006] A rotary motor is installed at the bottom of the main body of the heating machine, and a turntable is installed at the top of the rotary motor.

[0007] A locking rod is installed on the top of the turntable, and a silicone anti-slip pad is installed on the outer wall of the locking rod.

[0008] Preferably, the hot air vents are arranged in a circular array around the central axis of the heating machine body, and the limiting frame is welded to the heating machine body.

[0009] Preferably, the cover plate is movably connected to the slide groove, and the slide groove is symmetrically arranged with the central axis of the limiting frame as the center.

[0010] Preferably, the cover plate is telescopically connected to the limiting frame via a reset spring, and the pull rod is engaged with the limiting frame.

[0011] Preferably, the turntable is connected to the heating machine body via a rotary motor to form a rotating structure, and the turntable is movably connected to the heating machine body.

[0012] Preferably, the levers are arranged in a rectangular array with the central axis of the turntable as the center, and the silicone anti-slip pads are sleeved with the levers.

[0013] Preferably, the inner wall of the silicone anti-slip pad has an open design, and the silicone anti-slip pad is elastically designed.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model utilizes a limiting frame, a sliding groove, a cover plate, a pull rod, and a return spring. By pulling the pull rod outward and opening the cover plate along the sliding groove, the product wrapped in heat-shrink film is placed inside the heating machine body. Releasing the pull rod causes the cover plate to return to its original position via the spring force, covering the top of the heating machine body and creating a relatively sealed environment inside. This prevents rapid heat loss and avoids prolonged continuous use of the hot air blower, thus extending its service life.

[0016] This utility model, through the setting of a hot air blower, hot air outlet, rotary motor and turntable, when the product wrapped in heat shrink film is placed on the turntable, the rotary motor is started to drive the turntable to rotate at a uniform speed, so that the hot air outlet evenly heats the heat shrink film on the surface of the product. Compared with traditional manual heating, the surface of the heat shrink film is heated more evenly, and the wrapping quality is higher.

[0017] This invention utilizes a turntable, a locking rod, and a silicone anti-slip pad. The silicone anti-slip pad is fitted onto the locking rod, and the silicone anti-slip pad increases the friction with the product surface, preventing the product from sliding and falling when the turntable rotates. This also blocks the hot air vent from uniformly heating the heat-shrink film wrapped on the product surface, and increases the stability of the product during the heating process.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Please see Figure 1-4 A heat-shrinkable film heating device includes a heating machine body 1, a hot air blower 2 installed on the outer wall of the heating machine body 1, hot air outlets 3 installed on the outer wall of the hot air blower 2, a limit frame 4 installed on the outer wall of the heating machine body 1, a sliding groove 5 formed on the inner wall of the limit frame 4, a cover plate 6 installed on the inner wall of the sliding groove 5, a pull rod 7 installed on the outer wall of the cover plate 6, and a return spring 8 installed on the outer wall of the pull rod 7. The hot air outlets 3 are arranged in a circular array around the central axis of the heating machine body 1, and the limit frame 4 is welded to the heating machine body 1. The cover plate 6 is movably connected to the sliding groove 5, and the sliding groove 5 is symmetrically arranged around the central axis of the limit frame 4. The cover plate 6 is connected to the return spring. 8 and the limiting frame 4 form a telescopic structure, and the pull rod 7 is engaged with the limiting frame 4. Through the limiting frame 4, the slide groove 5, the cover plate 6, the pull rod 7 and the return spring 8, the pull rod 7 is pulled outward, and the cover plate 6 is opened along the slide groove 5. The product wrapped with heat shrink film is placed into the heating machine body 1. The pull rod 7 is released, and the cover plate 6 is reset by the elastic force of the return spring 8, covering the top of the heating machine body 1, so that the inside of the heating machine body 1 is in a relatively sealed state, so that the internal heat will not be lost quickly, and the hot air blower 2 will not be worn out due to long-term continuous use. The setting of the cover plate 6 extends the service life of the hot air blower 2.

[0026] Please see Figure 1-4A heat-shrinkable film wrapping heating device is disclosed. A rotary motor 9 is installed at the bottom of the heating machine body 1, and a turntable 10 is installed at the top of the rotary motor 9. The turntable 10 forms a rotating structure with the heating machine body 1 through the rotary motor 9, and the turntable 10 is movably connected to the heating machine body 1. When a product wrapped in heat-shrinkable film is placed on the turntable 10 through the hot air fan 2, hot air vent 3, rotary motor 9 and turntable 10, the rotary motor 9 is started to drive the turntable 10 to rotate at a uniform speed, so that the hot air vent 3 heats the heat-shrinkable film on the surface of the product evenly. Compared with traditional manual heating, the surface of the heat-shrinkable film is heated more evenly, and the wrapping quality is higher.

[0027] Please see Figure 1-4 A heat-shrink film coating and heating device is disclosed. A clamping rod 11 is installed on the top of a turntable 10. A silicone anti-slip pad 12 is installed on the outer wall of the clamping rod 11. The clamping rods 11 are arranged in a rectangular array with the central axis of the turntable 10 as the center. The silicone anti-slip pad 12 is sleeved with the clamping rod 11. The inner wall of the silicone anti-slip pad 12 is designed with openings and is elastic. The silicone anti-slip pad 12 is sleeved with the clamping rod 11 through the turntable 10, the clamping rod 11 and the silicone anti-slip pad 12. The setting of the silicone anti-slip pad 12 can increase the friction with the product surface and prevent the product from sliding and falling when the turntable 10 rotates. This can block the hot air vent 3 from uniformly heating the heat-shrink film wrapped on the product surface. The setting of the silicone anti-slip pad 12 increases the stability of the product during the heating process.

[0028] Working principle: In use, first move the device to the desired position, then wrap the heat-shrink film around the product surface. Next, attach the silicone anti-slip pad 12 to the locking rod 11. The silicone anti-slip pad 12 increases the friction with the product surface, preventing the product from sliding and falling when the turntable 10 rotates. This also blocks the hot air vent 3 from uniformly heating the heat-shrink film wrapped around the product surface. The silicone anti-slip pad 12 increases the stability of the product during the heating process. Then, pull the lever 7 outwards, opening the cover plate 6 along the slide groove 5. Place the product wrapped in heat-shrink film into the heating machine body 1. Release the lever 7, and the cover plate 6 will return to its original position by the elastic force of the return spring 8, thus aligning the heating machine body 1. The top is covered to keep the interior of the heating machine body 1 relatively sealed, thus preventing the rapid loss of internal heat and avoiding the wear and tear of the hot air blower 2 due to prolonged continuous use. The cover plate 6 extends the service life of the hot air blower 2. Finally, when the product wrapped in heat-shrink film is placed on the turntable 10, the rotary motor 9 is started to drive the turntable 10 to rotate at a uniform speed, so that the hot air port 3 heats the heat-shrink film on the surface of the product evenly. Compared with traditional manual heating, the surface of the heat-shrink film is heated more evenly, and the wrapping quality is higher. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
