Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, specifically to a heat shrink machine that is easy to adjust. Background Technology

[0002] During the operation of a heat shrink machine, the electronic components inside the control console continuously generate a large amount of heat. Existing heat dissipation devices often use fans in fixed positions for cooling, which have a concentrated airflow range and cannot cover the entire interior of the equipment. This can easily lead to localized heat accumulation, affecting the stability and lifespan of the equipment. At the same time, the heat dissipation vents are also easily clogged by dust, further reducing heat dissipation efficiency.

[0003] Existing heat shrink machines that are easy to adjust are unable to expand the heat dissipation coverage area of ​​the fan, thereby achieving efficient and uniform active heat dissipation inside the control console.

[0004] In view of this, we propose a heat shrink machine that is easy to adjust. Utility Model Content

[0005] The purpose of this utility model is to provide an easily adjustable heat shrink machine, which solves the problems of existing heat shrink machines where the cooling fan is fixed, resulting in limited heat dissipation range, uneven airflow distribution, and easy formation of local overheating.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An easily adjustable heat shrink machine includes a heat shrinking device, which includes a support platform. A heat shrinking mechanism is provided at the top of the support platform, and a control console is fixedly connected to the end of the heat shrinking mechanism away from the support platform. A heat dissipation hole is provided on one side of the control console. The machine also includes a heat dissipation device disposed inside the control console for dissipating heat from the control console. A cleaning device is disposed inside the control console for cleaning the heat dissipation hole. The heat dissipation device includes a rotating shaft, and a transmission belt is fitted on the circumferential surface of the rotating shaft.

[0007] Preferably, the heat dissipation device includes a motor, a rotating shaft is provided on the output shaft of the motor, a spring is fixedly connected in the groove of the rotating shaft, a slider is fixedly connected to the end of the spring away from the rotating shaft, a connecting plate is fixedly connected to the end of the slider away from the spring, a fan is fixedly connected to the top of the connecting plate, a limit plate passes through the end of the connecting plate away from the slider and is slidably connected to the limit plate, and a threaded sleeve is fitted on the thread of the rotating shaft.

[0008] Preferably, the circumferential surface of the rotating shaft is provided with a groove and a thread, the slider and the rotating shaft are slidably connected, the threaded sleeve and the thread on the rotating shaft are engaged with each other, and the end of the limiting plate away from the connecting plate is fixedly connected to the rotating shaft.

[0009] Preferably, the cleaning device includes a transmission belt, one end of which is fitted with a rotating rod, the end of the rotating rod away from the transmission belt is rotatably connected to a fixed plate, the end of the rotating rod away from the fixed plate is fixedly connected to a half gear, a guide plate is fixedly connected inside the control console, a spring telescopic rod is fixedly connected to the inner wall of the guide plate, a rack is fixedly connected to the end of the spring telescopic rod away from the guide plate, and a scraper is fixedly connected to one side of the rack.

[0010] Preferably, the end of the fixing plate away from the rotating rod is fixedly connected to the inner wall of the control console, and the half gear and the rack mesh with each other.

[0011] Preferably, a toothed rack is slidably connected to the inner wall of the guide plate, and the scraper is attached to the heat dissipation hole.

[0012] Preferably, the console has an internal cavity.

[0013] By employing the above technical solution, this utility model provides a heat shrink machine that is easy to adjust. It has at least the following beneficial effects: 1. This utility model drives the rotating shaft to rotate by starting the motor. The threaded sleeve that meshes with the rotating shaft moves axially accordingly. When the threaded sleeve moves forward, it pushes the connecting plate, which drives the slider to slide along the rotating shaft groove and compress the spring. This causes the fan fixed to the connecting plate to move forward and sweep air. When the threaded sleeve moves in the opposite direction and disengages from the compression, the spring releases its elastic potential energy, which pushes the slider and the connecting plate to reset the fan and perform reverse sweeping. The limiting plate guides and limits the movement of the connecting plate. The motor continues to run and eventually drives the fan to automatically reciprocate along the rotating shaft axis, thereby expanding the heat dissipation area and achieving uniform and efficient active heat dissipation inside the control console.

[0014] 2. This utility model uses a transmission belt to drive a rotating rod to rotate a half gear. When the toothed part of the half gear meshes with the rack, it pushes the rack to slide along the guide plate, allowing the spring telescopic rod to store energy. At the same time, the scraper fixed to the rack scrapes the surface of the heat dissipation hole once. When the half gear rotates to the toothless part, the meshing is released, the spring telescopic rod releases energy, drives the rack to slide back and reset, and the scraper completes the reverse scraping. Through the continuous rotation of the half gear and the elastic reset of the spring telescopic rod, the scraper is driven to reciprocate, realizing the automatic and continuous cleaning of the heat dissipation hole.

[0017] 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.

[0018] An easily adjustable heat shrink machine, such as Figure 1 - Figure 5 As shown, the device includes a heat shrinking device 1, which includes a support platform 101. A heat shrinking mechanism 102 is provided at the top of the support platform 101. A control console 103 is fixedly connected to the end of the heat shrinking mechanism 102 away from the support platform 101. A heat dissipation hole 104 is provided on one side of the control console 103. The device also includes a heat dissipation device 2, which is located inside the control console 103 and is used to dissipate heat from the control console 103. A cleaning device 3 is located inside the control console 103 and is used to clean the heat dissipation hole 104. The heat dissipation device 2 includes a rotating shaft 202, and a transmission belt 301 is sleeved on the circumferential surface of the rotating shaft 202.

[0019] The heat dissipation device 2 includes a motor 201, a rotating shaft 202 on the output shaft of the motor 201, a spring 203 fixedly connected in the groove of the rotating shaft 202, a slider 204 fixedly connected to the end of the spring 203 away from the rotating shaft 202, a connecting plate 205 fixedly connected to the end of the slider 204 away from the spring 203, a fan 206 fixedly connected to the top of the connecting plate 205, and a limiting plate 207 passing through the end of the connecting plate 205 away from the slider 204 and slidably connected to the limiting plate 207. A threaded sleeve 208 is fitted on the thread of the rotating shaft 202. The above design is advantageous because the slider 204 fixedly connected to the end of the spring 203 away from the rotating shaft 202 can release elastic potential energy when the threaded sleeve 208 does not compress the connecting plate 205, thereby pushing the slider 204 to reset along the groove of the rotating shaft 202, thereby driving the fan 206 to move in the opposite direction, providing reset power for the reciprocating motion of the fan 206.

[0020] The circumferential surface of the rotating shaft 202 is provided with a groove and a thread. The slider 204 is slidably connected to the rotating shaft 202. The threaded sleeve 208 and the thread on the rotating shaft 202 are engaged with each other. The end of the limiting plate 207 away from the connecting plate 205 is fixedly connected to the rotating shaft 202. The above design is conducive to the engagement of the threaded sleeve 208 and the thread on the rotating shaft 202. When the rotating shaft 202 rotates, the thread on its circumferential surface engages with the threaded sleeve 208, driving the threaded sleeve 208 to move axially along the rotating shaft 202.

[0021] The cleaning device 3 includes a transmission belt 301, with a rotating rod 302 sleeved at one end of the transmission belt 301. A fixed plate 303 is rotatably connected to the end of the rotating rod 302 away from the transmission belt 301, and a half gear 304 is fixedly connected to the end of the rotating rod 302 away from the fixed plate 303. A guide plate 305 is fixedly connected inside the control console 103, and a spring telescopic rod 306 is fixedly connected to the inner wall of the guide plate 305. A rack 307 is fixedly connected to the end of the spring telescopic rod 306 away from the guide plate 305, and a scraper 308 is fixedly connected to one side of the rack 307. The above design is advantageous because the rack 307 is fixedly connected to the end of the spring telescopic rod 306 away from the guide plate 305, so that when the half gear 304 rotates to the toothless area, the rebound force of the spring telescopic rod 306 will push the rack 307 to slide in the opposite direction, thereby realizing the reciprocating motion of the rack 307.

[0022] The end of the fixed plate 303 away from the rotating rod 302 is fixedly connected to the inner wall of the control console 103. The half gear 304 and the rack 307 mesh with each other. The above design is beneficial to convert the rotation of the half gear 304 into the linear movement of the rack 307 through the meshing of the half gear 304 and the rack 307.

[0023] A rack 307 is slidably connected to the inner wall of the guide plate 305, and a scraper 308 is pressed against the heat dissipation hole 104. The above design is beneficial because the scraper 308 is pressed against the heat dissipation hole 104 and can slide back and forth with the rack 307. The scraper 308 can continuously clean the dust, debris and other objects on the surface of the heat dissipation hole 104 to prevent the heat dissipation hole 104 from being blocked.

[0024] The control console 103 has an internal cavity, which provides a mounting platform for the components of the heat dissipation device 2 and the cleaning device 3.

[0025] In operation, this easily adjustable heat shrink machine first activates the motor 201, which drives the rotating shaft 202 to rotate. Since the rotating shaft 202 has both a groove and a thread on its circumference, the slider 204 slides into the groove, while the threaded sleeve 208 engages with the thread. As the rotating shaft 202 rotates, the thread engagement drives the threaded sleeve 208 to move axially along the shaft 202. When the threaded sleeve 208 moves towards the connecting plate 205, its end presses against the connecting plate 205, causing the connecting plate 205 to drive the slider 204 to slide along the groove and compress the spring 203. The fan 206, fixedly connected to the connecting plate 205, moves in the same direction, thus providing airflow cooling within the control console 103 in the first direction. When the threaded sleeve 208 moves in the opposite direction as the threads engage and disengages from the pressure on the connecting plate 205, the compressed spring 203 releases its elastic potential energy, pushing the slider 204 back to its original position along the groove. This, in turn, drives the fan 206 to move in the opposite direction via the connecting plate 205, achieving a return stroke. The sliding contact between the limiting plate 207 and the connecting plate 205 guides and limits the movement of the connecting plate 205, ensuring its translational stability. Thus, continuous operation of the motor 201 drives the fan 206 to reciprocate linearly along the axis of the rotating shaft 202, thereby expanding the heat dissipation coverage area of ​​the fan 206 and achieving efficient and uniform active heat dissipation inside the control console 103.

[0026] Then, the rotating rod 302 is driven to rotate via the transmission belt 301. The rotating rod 302 is rotatably connected to the inner wall of the control panel 103 via the fixing plate 303, and a half gear 304 is fixedly connected to one end of it. When the rotating rod 302 rotates, it drives the half gear 304 to rotate synchronously. When the toothed part of the half gear 304 meshes with the rack 307, the rotational motion of the half gear 304 is converted into the linear motion of the rack 307 through the meshing pair of the half gear 304 and the rack 307. The rack 307 slides in one direction along the inner wall of the guide plate 305, which is slidably connected to it. During this process, the spring telescopic rod 306, which is fixedly connected to the rack 307, is compressed or stretched, storing elastic potential energy; at the same time, the scraper 308, which is fixed to one side of the rack 307 and keeps in close contact with the surface of the heat dissipation hole 104, moves accordingly, performing the first scraping and cleaning of the surface of the heat dissipation hole 104. When the half gear 304 continues to rotate to its toothless area, the meshing between the rack 307 and the half gear 304 is released. At this time, the compressed or stretched spring telescopic rod 306 releases its stored elastic potential energy, and the resulting rebound force drives the rack 307 to slide in the opposite direction along the guide plate 305, realizing the reset movement. During the reset process, the scraper 308 scrapes and cleans the surface of the heat dissipation hole 104 in the opposite direction again. Through the continuous rotation of the rotating rod 302 and the half gear 304, and the elastic reset action of the spring telescopic rod 306, the rack 307 and the scraper 308 are driven to perform automatic reciprocating linear motion, thereby realizing continuous cleaning of the outer surface of the heat dissipation hole 104, effectively preventing dust and debris from clogging the heat dissipation hole 104, and ensuring the heat dissipation efficiency of the control console 103.
