Description

Technical Field

[0001] This utility model relates to the field of processing and manufacturing technology of vapor phase rust inhibitors, and in particular to a heat shrink machine with air purification. Background Technology

[0002] Heat shrink wrappers are devices that use heat to shrink heat shrink film to package products. They are widely used in many industries such as food and beverage, pharmaceuticals and health care. They have many advantages, such as protecting products, improving appearance, facilitating transportation and storage, high cost-effectiveness, and being environmentally friendly and recyclable. Heat shrink wrappers require air purification during operation because it can protect personnel from harmful gases and ensure their health, ensure that exhaust emissions meet environmental regulations, prevent impurities from affecting product quality, prevent harmful substances from corroding the equipment to extend equipment life and reduce maintenance costs.

[0003] A search revealed Chinese Patent Publication No. CN213974738U, which discloses a heat shrink machine, including a base, a heat shrink machine body, and a conveying device. The heat shrink machine body is mounted on the base and forms a heat shrinking chamber. The conveying device passes through the heat shrinking chamber. An air filter and an exhaust fan are located on the upper part of the heat shrink machine body, connected by an air duct. One end of the air duct is connected to the heat shrinking chamber inside the heat shrink machine body. A support is fixedly connected to the inner wall of the heat shrinking chamber, and a heating pipe is mounted on the support. An insulation layer is provided inside the casing wall of the heat shrink machine body. This invention, by setting up an air filter and an exhaust fan connected to the heat shrinking chamber, performs four-stage filtration of the air inside the heat shrinking chamber, fully absorbing harmful substances and preventing pollution of the working environment.

[0004] The aforementioned patent specification mentions that "by setting up an air filtration device and exhaust fan connected to the furnace cavity, the air inside the furnace cavity is filtered in four stages to fully absorb harmful substances and prevent pollution of the working environment; by setting heating pipes on the inner wall of the furnace cavity and setting a heat insulation layer inside the box wall, as well as cooperating with heat insulation curtains set at the furnace cavity outlet and inlet, the temperature inside the furnace cavity can be raised rapidly, preventing excessive heat from escaping to the outside environment, and facilitating the heating of product packaging." While the aforementioned patent can achieve gas filtration, the filter plates need to be replaced after prolonged use, and the above method cannot achieve the effect of replacing the filter plates. Therefore, a heat shrink machine with air purification is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a heat shrink machine with air purification, which aims to improve the problem of cement mortar sticking to the inner wall of the mixing tank in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heat shrink machine with air purification includes a base plate, a heat shrink mechanism fixedly connected to the top of the base plate, an air purification mechanism fixedly connected to the top of the heat shrink mechanism, a conveyor belt fixedly connected to the top of the base plate, and a driving mechanism fixedly connected to the top of the conveyor belt.

[0008] The air purification mechanism includes an air pump, the bottom of which is fixedly connected to the top of the heat shrink mechanism. A transmission pipe is fixedly connected to the top of the air pump, and a housing is fixedly connected to the other end of the transmission pipe. Multiple fixed frames are fixedly connected inside the housing, and filter plates are slidably connected inside the fixed frames. An adjustment component is slidably connected to the outside of the driving mechanism.

[0009] The above method involves placing the item on a conveyor belt, which then transports it to the top of the conveyor belt. The cylinder is activated, causing the hollow rod and sliding rod to move downwards. The sliding rod slides within the angled section of the connecting block, and a spring pushes the sliding rod to abut the connecting block, causing the adjusting rod to slide the rotating plate at the top of the conveyor belt. After the item is centered, it is reset, ensuring accurate entry into the heat shrink box. When the heat shrink box generates harmful gases, the vacuum pump is activated, drawing the gas into the outer casing through a transmission pipe. A filter plate inside the casing filters and purifies the gas. After prolonged use, the filter plate can be removed and replaced via an extension plate to maintain purification effectiveness and a safe working environment.

[0010] As a further description of the above technical solution:

[0011] The adjustment assembly includes two connecting blocks. The interior of the connecting blocks is slidably connected to the outside of the driving mechanism. An adjustment rod is fixedly connected to the bottom of the connecting blocks, and a rotating plate is slidably connected to the end of the adjustment rod away from the connecting blocks.

[0012] The above scheme works by driving the mechanism to make the connecting block slide on its outer side, and the adjusting rod at the bottom of the connecting block moves accordingly. The other end of the adjusting rod slides inside the rotating plate, driving the rotating plate to move. By sliding the rotating plate, the position of the items on the conveyor belt can be adjusted to ensure that the items enter the heat shrink box in the center position.

[0013] As a further description of the above technical solution:

[0014] The heat shrinking mechanism includes a base, the bottom of which is fixedly connected to the top of the base plate, a conveyor belt fixedly connected to the top of the base, a heat shrink box fixedly connected to the top of the conveyor belt, and curtains fixedly connected to both sides of the heat shrink box.

[0015] The above method involves the following steps: the items are conveyed from the conveyor belt to the heat shrink box, where they are heated to shrink the heat shrink film and complete the packaging. The curtains on both sides can block heat loss, maintain a stable temperature inside the heat shrink box, and prevent heat leakage and the spread of harmful gases, ensuring that the heat shrinking process is efficient and safe.

[0016] As a further description of the above technical solution:

[0017] The driving mechanism includes a limiting frame, the bottom of which is fixedly connected to the top of the conveyor belt. A cylinder is fixedly connected inside the limiting frame, and a hollow rod is fixedly connected to the driving end of the cylinder. A sliding rod is slidably connected inside the hollow rod, and the end of the sliding rod away from the hollow rod is slidably connected inside the connecting block.

[0018] The above solution involves: starting the cylinder, which drives the hollow rod to move, causing the sliding rod inside the hollow rod to slide. The other end of the sliding rod slides inside the connecting block, which has a special structure. As the sliding rod moves down, the spring force and the angled design push the connecting block to move. The connecting block drives the adjusting rod, which in turn causes the rotating plate to slide on the conveyor belt, adjusting the position of the item. When the cylinder moves in the reverse direction, it drives all components to reset. Through the cyclical operation of the driving mechanism, the item is continuously kept in the center position on the conveyor belt, providing accurate item positioning for the subsequent heat shrinking process.

[0019] As a further description of the above technical solution:

[0020] The rotating plate has a sliding groove inside, and the bottom of the rotating plate is slidably connected to the top of the conveyor belt;

[0021] The above solution involves adjusting the rod within the sliding groove of the rotating plate. By changing the contact position with the groove, the rotating plate is pushed to slide on top of the conveyor belt. The guiding effect of the sliding groove allows the rotating plate to be flexibly adjusted, enabling precise positioning and correction of items on the conveyor belt, ensuring that items are smoothly transported to the heat shrink box along the center of the conveyor belt.

[0022] As a further description of the above technical solution:

[0023] A spring is fixedly connected inside the hollow rod, and the other end of the spring is fixedly connected to the inside of the sliding rod.

[0024] The above solution works as follows: when the cylinder drives the hollow rod downward, the sliding rod is blocked by the connecting block and compresses the spring. As the sliding rod slides down, the internal space of the connecting block changes, and the spring recovers its deformation and pushes the sliding rod outward, enabling it to push the connecting block and drive the adjusting rod and the rotating plate to move. When the cylinder pulls the hollow rod up, the spring assists the sliding rod to reset, thus realizing the cyclic adjustment of the item's position.

[0025] As a further description of the above technical solution:

[0026] An extension plate is fixedly connected to the outside of the filter plate, and the outside of the extension plate is slidably connected to the inside of the outer shell.

[0027] The above solution involves an air pump drawing harmful gases from the heat-shrink box into the outer casing via a transmission pipe. The gases are then purified by the filter plate. After prolonged use, the extension plate can be pulled out and replaced by sliding it inside the casing. Once replaced, the extension plate can be pushed in the opposite direction to slide the new filter plate into the fixed frame inside the casing, ensuring continuous and effective air purification.

[0028] As a further description of the above technical solution:

[0029] A fixing block is fixedly connected to the top of the connecting block, and a sliding groove is slidably connected to the outside of the fixing block. The top of the sliding groove is fixedly connected to the inside of the limiting frame.

[0030] With the above solution: when the sliding rod pushes the connecting block to move, the fixed block at the top of the connecting block slides in the groove within the limiting frame. The groove provides guidance and limit for the fixed block, ensuring that the connecting block can only move smoothly in a specific direction, thereby enabling the adjusting rod and rotating plate to accurately adjust the position of the item and ensure the stability of the item transmission path.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, by activating an air pump in conjunction with a transmission pipe, which in turn connects to a housing, which in turn connects to a fixed frame, which in turn connects to a filter plate, and which in turn connects to an extension plate, harmful gases generated in the heat shrink box can be filtered. If the harmful gases generated by the heat shrink box are directly released into the air, they will be inhaled by workers, and long-term exposure may lead to respiratory diseases, poisoning, and other health problems. The filtration system composed of the air pump, transmission pipe, housing, fixed frame, and filter plate can effectively remove harmful substances from the harmful gases, reduce the risk of workers being exposed to harmful gas environments, and protect their respiratory system and overall health.

[0033] 2. In this utility model, the hollow rod is driven by the starting cylinder, which in turn drives the sliding rod, which in turn drives the connecting block, which in turn drives the adjusting rod, which in turn drives the rotating plate. This achieves the adjustment of the item's position, ensuring that the item is accurately located in the center of the conveyor belt and enters the heat shrink box, avoiding positional deviation. This allows the heat shrink film to be evenly wrapped around the item, improving the quality and appearance of the heat shrink packaging and reducing packaging defects caused by improper item positioning, such as wrinkles in the heat shrink film or loose wrapping.

[0040] 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.

[0041] Reference Figures 1 to 3 The present invention provides an embodiment of a heat shrink machine with air purification, including a base plate 1. The base plate 1 serves as the basic support component of the entire device, which can stably support the components above and ensure the stability of the device during operation. A heat shrink mechanism 2 is fixedly connected to the top of the base plate 1. The heat shrink mechanism 2 is used for heat shrink packaging of items. Its precise heating design enables the heat shrink film to shrink quickly and evenly, tightly wrapping the items. An air purification mechanism 3 is fixedly connected to the top of the heat shrink mechanism 2. The air purification mechanism 3 can promptly handle the harmful gases generated during the heat shrinking process, prevent them from spreading into the working environment, and ensure air quality.

[0042] A conveyor belt 4 is fixedly connected to the top of the base plate 1. The conveyor belt 4 is responsible for smoothly transporting the items to the heat shrinking mechanism 2. Its stable transmission performance ensures that the items will not shift or fall during transportation. A driving mechanism 5 is fixedly connected to the top of the conveyor belt 4. The driving mechanism 5 can drive the adjustment component 56 to operate, thereby accurately adjusting the position of the items on the conveyor belt 4 to ensure that the items are in the right position when they enter the heat shrinking mechanism 2. The air purification mechanism 3 includes an air pump 31. The air pump 31 can generate strong suction to quickly suck the harmful gases generated by the heat shrinking mechanism 2 into the transmission pipe 32. The bottom of the air pump 31 is fixedly connected to the top of the heat shrinking mechanism 2. This connection method allows the air pump 31 to efficiently extract the harmful gases generated by the heat shrinking mechanism 2 at close range, improving the purification efficiency. A transmission pipe 32 is fixedly connected to the top of the air pump 31. The transmission pipe 32 is responsible for transporting the harmful gases extracted by the air pump 31 to the outer shell 33. Its reasonable pipe diameter design ensures the smoothness of gas transportation.

[0043] The other end of the transmission pipe 32 is fixedly connected to the outer shell 33. The outer shell 33 serves as the main space for gas purification and can accommodate the fixed frame 34 and the filter plate 35, providing sufficient processing space for gas purification. Multiple fixed frames 34 are fixedly connected inside the outer shell 33. The fixed frames 34 can stably fix the filter plate 35, ensuring that the filter plate 35 remains stable in position during gas purification and fully exerts its filtering function. The filter plate 35 is slidably connected inside the fixed frame 34. The filter plate 35 can efficiently adsorb and filter impurities and harmful substances in harmful gases, so that the discharged gas meets safety standards.

[0044] An extension plate 36 is fixedly connected to the outside of the filter plate 35. The extension plate 36 facilitates the installation and removal of the filter plate 35 by the operator, and makes it easy to replace the filter plate 35 in a timely manner after a period of use. The outside of the extension plate 36 is slidably connected to the inside of the outer shell 33. This sliding connection method makes the replacement operation of the filter plate 35 simple and quick, and ensures that the filter plate 35 is stable and does not shake during operation. An adjustment component 56 is slidably connected to the outside of the driving mechanism 5. Under the drive of the driving mechanism 5, the adjustment component 56 can flexibly adjust the position of the item on the conveyor belt 4 to ensure that the item is in the center position when it enters the heat shrinking mechanism 2, thereby improving the quality of heat shrink packaging.

[0045] Specifically, the equipment is supported by a base plate 1. The conveyor belt 4 smoothly transports the items to the heat shrinking mechanism 2. The heat shrinking mechanism 2 uses precise heating to tightly wrap the items with heat shrink film, driving the mechanism 5 to drive the adjustment component 56. Utilizing components such as cylinder 52, hollow rod 53, and sliding rod 55, the rotating plate 563 slides on the conveyor belt 4, ensuring that the items are centered on the conveyor belt before entering the heat shrinking mechanism 2, thus ensuring the accuracy of heat shrink packaging. Harmful gases generated during the heat shrinking process are treated by the air purification mechanism 3. The air pump 31, with its strong suction, quickly draws the harmful gases generated by the heat shrinking mechanism 2 into the outer shell 33 through the transmission pipe 32. The filter plate 35 inside the outer shell 33, under the stable fixation of the fixed frame 34, efficiently adsorbs and filters harmful gases. After the filter plate 35 has been used for a period of time, the operator can easily disassemble and replace it through the extension plate 36 to ensure continuous and effective air purification and protect the working environment.

[0046] Reference Figure 1 , Figure 2 and Figure 4 The adjustment component 56 includes two connecting blocks 561. The two connecting blocks 561 work together to calibrate the position of the item from both sides, ensuring balanced adjustment force and making the item more accurately positioned on the conveyor belt 4. A fixing block 564 is fixedly connected to the top of the connecting block 561. The fixing block 564 is firmly connected to the connecting block 561, providing a stable guiding foundation for the connecting block 561 during movement and preventing it from shifting. A sliding groove 565 is slidably connected to the outside of the fixing block 564. The sliding groove 565 limits and guides the fixing block 564, ensuring that the connecting block 561 can only slide along a specific direction, thereby making the adjustment path of the item stable and controllable.

[0047] The connecting block 561 is internally slidably connected to the outside of the driving mechanism 5. This connection method allows the connecting block 561 to stably receive the power transmitted by the driving mechanism 5 and accurately convert the power into its own sliding motion to adjust the position of the item. The bottom of the connecting block 561 is fixedly connected to the adjusting rod 562, which transmits the movement of the connecting block 561 to the rotating plate 563. Its stable connection ensures that there is no energy loss during the power transmission process and ensures that the adjustment action is executed accurately. The end of the adjusting rod 562 away from the connecting block 561 is slidably connected to the rotating plate 563. The rotating plate 563 can slide flexibly under the drive of the adjusting rod 562. By changing the contact position with the item, the position of the item can be finely adjusted to ensure that the item is in the center of the conveyor belt 4.

[0048] The rotating plate 563 has a sliding groove inside, which provides sliding space for the adjusting rod 562, making the adjusting rod 562 more flexible and smooth when driving the rotating plate 563. The sliding distance of the rotating plate 563 can be precisely controlled according to actual needs. The bottom of the rotating plate 563 is slidably connected to the top of the conveyor belt 4. The sliding connection between the rotating plate 563 and the top of the conveyor belt 4 allows it to slide smoothly on the surface of the conveyor belt 4, effectively avoiding jamming when adjusting the position of the item, and ensuring the continuity and efficiency of the adjustment action.

[0049] Specifically, the adjustment component 56 achieves precise positioning of the item through the coordinated operation of its various parts. Driven by the driving mechanism 5, the two connecting blocks 561 calibrate the position of the item from both sides, ensuring balanced adjustment force and more accurate positioning. The fixing block 564 on the top of the connecting block 561 cooperates with the slide groove 565 to limit its sliding direction and ensure stable and controllable movement path. At the same time, the sliding connection between the connecting block 561 and the driving mechanism 5 allows it to stably receive power and convert it into its own sliding. The adjustment rod 562 at the bottom of the connecting block 561 transmits the motion to the rotating plate 563. The solid connection ensures lossless power transmission. The sliding groove inside the rotating plate 563 provides flexible sliding space for the adjustment rod 562. Combined with its sliding connection with the top of the conveyor belt 4, the rotating plate 563 can flexibly and smoothly change its contact position with the item, making fine adjustments to the item and ensuring that it is always in the center position of the conveyor belt 4, providing a precise foundation for subsequent heat shrink packaging.

[0050] The heat shrink mechanism 2 includes a base 21, which provides solid and stable support for the entire heat shrink mechanism 2, ensuring that it will not shake or shift during operation and ensuring smooth heat shrinking operation. The bottom of the base 21 is fixedly connected to the top of the base plate 1. This stable connection makes the heat shrink mechanism 2 and the base plate 1 form a whole, enhancing the overall stability of the equipment and enabling it to withstand various forces during the heat shrinking process. The top of the base 21 is fixedly connected to a conveyor belt 22, which is responsible for smoothly transporting the items into the heat shrink box 23. Its stable transmission performance can ensure that the items maintain a suitable speed and position during the transport process.

[0051] A heat shrink box 23 is fixedly connected to the top of the conveyor belt 22. The heat shrink box 23 is the core component for heat shrink packaging. It can generate uniform and stable heat, which causes the heat shrink film of the packaged item to shrink quickly and fit tightly to the item. Curtains 24 are fixedly connected to both sides of the heat shrink box 23. The curtains 24 can effectively block the heat loss inside the heat shrink box 23, maintain the stable temperature inside the box, and at the same time, can also prevent harmful gases generated during the heat shrinking process from spreading outward to a certain extent, thus improving the working environment.

[0052] Specifically, the heat shrinking mechanism 2 is supported by the base 21, and its bottom is fixed to the base plate 1 to enhance the overall stability of the equipment and ensure smooth heat shrinking operation. The conveyor belt 22 on the top of the base 21 stably transports the items to the heat shrink box 23. As the core component, the heat shrink box 23 generates uniform and stable heat to shrink the heat shrink film and wrap the items. The curtains 24 on both sides of the heat shrink box 23 can not only block heat loss and maintain the stable temperature inside the box, but also prevent the diffusion of harmful gases to a certain extent, thus ensuring that the heat shrinking packaging process is efficient, safe and environmentally friendly.

[0053] The driving mechanism 5 includes a limiting frame 51, which provides a stable support structure for the entire driving mechanism 5, ensuring that the internal components remain stable during operation and preventing shaking due to external forces. The top of the slide 565 is fixedly connected to the inside of the limiting frame 51. This connection method enables the slide 565 to stably provide guidance and limit for the fixed block 564, ensuring the accuracy of the movement of the adjustment component 56. The bottom of the limiting frame 51 is fixedly connected to the top of the conveyor belt 4, tightly connecting the driving mechanism 5 with the conveyor belt 4, so that the driving mechanism 5 can directly adjust the position of the items on the conveyor belt 4.

[0054] A cylinder 52 is fixedly connected inside the limiting frame 51. The cylinder 52 serves as a power source, capable of outputting a stable and controllable driving force to provide reliable power for the operation of the drive mechanism 5. A hollow rod 53 is fixedly connected to the drive end of the cylinder 52. This connection can accurately transmit the power of the cylinder 52 to the hollow rod 53, causing the hollow rod 53 to move in a predetermined direction and stroke. A spring 54 is fixedly connected inside the hollow rod 53. The spring 54 plays the role of storing energy and assisting in the hollow rod 53. Together with the movement of the sliding rod 55, it realizes the pushing and resetting of the connecting block 561.

[0055] The other end of the spring 54 is fixedly connected to the inside of the sliding rod 55, ensuring that the spring 54 can effectively act on the sliding rod 55, releasing or storing energy at the appropriate time to ensure smooth and continuous driving action. The sliding rod 55 is slidably connected inside the hollow rod 53. The sliding connection between the two allows the sliding rod 55 to move flexibly inside the hollow rod 53 while maintaining the stability of the movement, which facilitates the control of the connecting block 561. The end of the sliding rod 55 away from the hollow rod 53 is slidably connected to the inside of the connecting block 561. This connection allows the sliding rod 55 to transmit power to the connecting block 561, driving the adjustment component 56 to make precise adjustments to the position of the item.

[0056] Specifically, the driving mechanism 5 is supported by the limiting frame 51, and its bottom is connected to the conveyor belt 4. It can directly adjust the position of the items on the conveyor belt 4. The cylinder 52 fixed inside the limiting frame 51 serves as a power source and can output a stable and controllable driving force. The hollow rod 53 connected to the driving end of the cylinder 52 can accurately receive power and move in a predetermined direction and stroke. The spring 54 inside the hollow rod 53 is connected to the sliding rod 55, which plays a role in energy storage and assistance. It releases or stores energy at the appropriate time to ensure smooth and continuous action. The sliding rod 55 slides flexibly and stably inside the hollow rod 53. One end of it is slidably connected to the connecting block 561, which can transmit power to the connecting block 561 to drive the adjustment component 56. At the same time, the slide groove 565 is fixed inside the limiting frame 51 to provide a guide limit for the fixed block 564, ensuring that the adjustment component 56 moves accurately and achieves precise adjustment of the position of the items.

[0057] Working principle: When the worker needs to heat shrink an item, the item is placed on top of the conveyor belt 4. The conveyor belt 4 is then activated to transport the item to the top of the conveyor belt 22. At this point, the cylinder 52 is activated, driving the hollow rod 53 downwards. The hollow rod 53 has a sliding rod 55 connected inside, which is also driven downwards. The other end of the sliding rod 55 slides inside the connecting block 561, which has an angled interior. As the sliding rod 55 slides downwards with the hollow rod 53, it fits against the outside of the angled interior of the connecting block 561. The original sliding rod 55 was held down by the connecting block 561. As the sliding rod 55 slides down, the space inside the connecting block 561 increases, causing it to be compressed. Spring 54 pushes sliding rod 55 outward. When sliding rod 55 slides to the bottom inside connecting block 561, it pushes connecting block 561 outward. At this time, connecting block 561 moves, thereby driving adjusting rod 562. The other end of adjusting rod 562 slides inside rotating plate 563. Rotating plate 563 then slides on top of conveyor belt 4 because adjusting rod 562 slides inside it. After sliding down to a certain extent, cylinder 52 pulls hollow rod 53 upward, which brings adjusting rod 562 back to its original position, so that rotating plate 563 returns to its original position again. At this time, the two rotating plates 563 can slide continuously, thereby ensuring that the item slides in the center of conveyor belt 4 and avoids changes in position when entering heat shrink box 23.

[0058] When the heat shrink box 23 heats and shrinks an item, harmful gases are generated. At this time, the vacuum pump 31 can be started, and the suction of the vacuum pump 31 is transmitted to the inside of the heat shrink box 23 through the transmission pipe 32. The gas inside the transmission pipe 32 can then be drawn into the inside of the outer shell 33. The inside of the outer shell 33 is equipped with multiple filter plates 35, which can filter the gas. However, when the filter plates 35 have been used for too long, the filtration effect will be poor. At this time, the filter plates 35 can be removed from the inside of the outer shell 33 through the extension plate 36. After replacing the filter plates 35, the outer side of the filter plates 35 is aligned with the inside of the fixing frame 34 and the filter plates 35 are slid in.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
