Description

Technical Field

[0001] This utility model relates to the field of heat sealing and cutting technology, and in particular to a low-dust integrated heat sealing and cutting device for cleanrooms. Background Technology

[0002] In industries such as food, pharmaceuticals, and electronic components, which have stringent requirements for the cleanliness of the production environment, cleanrooms are the core setting for ensuring product quality. The heat-sealing and cutting integrated device is used to heat-seal film packaging materials to form a sealed structure and cut them into packaging bags of specified sizes. At the same time, it is necessary to strictly control the plastic debris and film dust generated during the heat-sealing and cutting process to avoid contaminating the workshop environment or adhering to the product surface.

[0003] The existing heat sealing and cutting device suitable for cleanrooms mainly consists of a fixed-height unwinding frame, a single conveyor belt, a cylinder-driven heat sealing and cutting module, and an independent dust cover. In terms of technical principle, the operator first needs to fix the film roll on the fixed-height unwinding frame. The film is directly conveyed to the bottom of the heat sealing and cutting module via a single conveyor belt. The heat sealing knife is heated to a set temperature by electricity and then, driven by a cylinder, it fits against the fixed base below to achieve heat sealing. At the same time, the cutting knife moves down synchronously with the heat sealing knife to complete the cutting. To control dust, the device only adds a fixed transparent dust cover to the outside of the heat sealing and cutting module.

[0004] Existing cleanroom heat sealing and cutting devices use a fixed-height unwinding roller, making it difficult to adjust the unwinding height according to changes in film roll diameter and conveyor belt position. When the initial diameter of the film roll is small or the unwinding frame height is too low, the path from the unwinding roller to the conveyor belt is too long, resulting in excessive tension fluctuations when entering the heat sealing and cutting module, inconsistent cutting dimensions, and a low finished product qualification rate. Therefore, a low-dust integrated heat sealing and cutting device for cleanrooms is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a low-dust heat-sealing and cutting integrated device for cleanrooms, which aims to improve the problem that it is difficult to adjust the unwinding height according to the change of film roll diameter and the position of the conveyor belt due to the fixed height design of the unwinding roller.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-dust heat-sealing and cutting integrated device for cleanrooms, comprising a base plate, a conveyor belt 1 and a conveyor belt 2 arranged inside the base plate, a fixing frame 2 fixedly connected to the inner wall of the base plate, a heat-sealing strip and a cutter arranged inside the fixing frame 2, a fixing frame 1 fixedly connected to the upper surface of the base plate, a sleeve slidably connected to the inner wall of the fixing frame 1, an unwinding roller rotatably connected to the inner wall of the sleeve, and an adjustment component arranged on the outer wall of the fixing frame 1; The adjustment assembly includes a slide rail, a first sliding block, and a lead screw. The outer wall of the slide rail is fixedly connected to the outer wall of the first fixed frame. The inner wall of the first sliding block is slidably connected to the outer wall of the slide rail. The outer wall of the lead screw is threadedly connected to the inner wall of the first sliding block. A handwheel is fixedly connected to the outer wall of the lead screw. A cylinder is fixedly connected to the inner wall of the second fixed frame. A connecting block is fixedly connected to the output end of the cylinder. A buffer assembly is provided on the outer wall of the connecting block.

[0007] Through the above technical solution, the base plate provides stable support, and the integrated conveyor belt one and conveyor belt two realize the connection of film and finished product transportation. The film unwinding is completed with the help of the fixed frame one, sleeve and unwinding roller. The height of the unwinding roller is flexibly adjusted by the adjustment component to solve the problem of improper initial height of the unwinding roller. At the same time, the fixed frame two, cylinder and connecting block provide the power foundation for heat sealing and cutting, and the buffer component prepares for the pressure buffer of subsequent heat sealing and cutting. The whole lays the structural and adjustment foundation for heat sealing and cutting operation.

[0008] Preferably, the buffer assembly includes a first buffer block and a second buffer block. The upper end of the first buffer block is fixedly connected to the outer wall of the connecting block, and the lower end of the first buffer block is fixedly connected to the upper surface of the heat-sealing strip. The upper end of the second buffer block is fixedly connected to the outer wall of the connecting block, and the lower end of the second buffer block is fixedly connected to a second sliding block. The outer wall of the second sliding block is slidably connected to the inner wall of the connecting block, and the lower surface of the second sliding block is fixedly connected to the outer wall of the cutter. A base is provided below the cutter, and the outer wall of the base is fixedly connected to the inner wall of the second fixing frame.

[0009] Through the above technical solutions, buffer block one can absorb the downward impact force during heat sealing by the heat sealing strip, preventing the film from being damaged due to excessive heat sealing pressure or over-heat sealing, thus ensuring the heat sealing quality. Buffer block two, together with sliding block two, can absorb rigid collision force during cutting by the cutter, preventing damage to the cutter and ensuring a smooth cut. At the same time, the base provides precise support for the cutter, effectively improving the heat sealing cutting quality and the service life of core components.

[0010] Preferably, a dustproof plate is fixedly connected to the upper surface of the base plate, and symmetrical baffles are fixedly connected to the inner wall of the dustproof plate.

[0011] Through the above technical solution, the dustproof plate provides an installation carrier for the baffle. The symmetrical baffle can initially block the spread of flying dust during the heat sealing and cutting process, avoid the direct pollution of the cleanroom environment by flying dust, create favorable conditions for subsequent flying dust collection and treatment, and meet the production requirements of the cleanroom.

[0012] Preferably, the inner wall of the dustproof plate is fixedly connected to a symmetrical pipe, and the outer wall of the pipe is fixedly connected to a collection box.

[0013] Through the above technical solution, a dust conveying channel is built. The left and right symmetrical pipes connect the dustproof plate and the collection box, which can guide the dust initially blocked in the area of ​​the dustproof plate to the collection box, realize the directional conveying of dust from the generation area to the collection area, and provide path support for the centralized treatment of dust.

[0014] Preferably, a fan is provided on one side of the outer wall of the collection box, and the output end of the fan is fixedly connected to a second pipe.

[0015] Through the above technical solution, the fan generates negative pressure after starting, and forms an airflow channel through the cooperation of pipe 2 and pipe 1, which provides power for the dust to enter the collection box from the dustproof plate through pipe 1, ensuring that the dust can be effectively sucked into the collection box and guaranteeing the dust collection efficiency.

[0016] Preferably, the outer wall of the second pipe is fixedly connected to the inner wall of the collection box, and the inner wall of the collection box is slidably connected to the first sliding box.

[0017] Through the above technical solution, the second pipe connects the fan and the collection box, so that the negative pressure generated by the fan can form a stable airflow in the collection box. At the same time, the sliding box 1, which is slidably connected in the collection box, provides installation and housing space for subsequent dust filtration, ensuring the continuity of the dust collection process.

[0018] Preferably, a filter plate is fixedly connected to the inner wall of the first sliding box, and a second sliding box is slidably connected to the inner wall of the collection box.

[0019] Through the above technical solution, the filter plate can filter out larger particles in the dust, preventing large dust particles from clogging the pipes or affecting subsequent processing. The second sliding box works in conjunction with the first sliding box to collect dust particles of different sizes, which facilitates targeted subsequent treatment and improves the precision of dust treatment.

[0020] Preferably, a dust cover is fixedly connected to the inner wall of the second sliding box, and the second sliding box is located below the first sliding box.

[0021] Through the above technical solutions, the dust cover can prevent fine dust from entering the fan with the airflow, avoiding the accumulation of dust in the fan and causing fan failure. At the same time, the second sliding box is located below the first sliding box, ensuring that the filtered fine dust can be collected smoothly, ensuring the stable operation of the dust collection structure and the integrity of dust collection.

[0022] This utility model has the following beneficial effects: 1. In this utility model, the height adjustment mechanism, composed of a handwheel, lead screw, and sliding block, can flexibly adjust the height of the unwinding roller, effectively avoiding problems such as excessively long film paths and loose wrinkles caused by an initially low unwinding roller height. This stabilizes the tension in the subsequent heat-sealing and cutting process from the source, reducing the impact of tension fluctuations on processing accuracy and ensuring precise alignment between the film conveying and heat-sealing / cutting positions. At the same time, the buffer block on the heat-sealing strip absorbs the impact force during heat sealing, preventing the film from being damaged due to excessive heat-sealing pressure or over-sealing. The buffer block on the cutter buffers rigid collisions during cutting, preventing damage to the cutter and ensuring a smooth cut. This not only improves the processing quality of the packaging bag but also extends the service life of core components such as the heat-sealing strip and cutter, reducing equipment maintenance costs.

[0023] 2. In this utility model, during the heat-sealing and cutting process, the symmetrical baffles inside the dustproof plate can initially block the spread of flying dust, preventing flying dust from polluting the cleanroom environment and meeting the requirements of clean production. Subsequently, the fan forms a negative pressure through pipe one and pipe two, sucking the flying dust into the collection box. With the help of the filter plate in sliding box one, the flying dust is graded and treated. Filtering larger flying dust particles can prevent pipe blockage, while fine flying dust enters sliding box two for subsequent centralized disposal, avoiding the accumulation of flying dust from affecting equipment operation. In addition, the dust cover can prevent flying dust from entering the fan, preventing the fan from malfunctioning due to flying dust accumulation. This not only ensures the environmental quality of the cleanroom but also ensures the stable operation of the dust collection structure and the entire equipment, reducing the frequency of downtime and maintenance caused by flying dust problems.

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0027] Reference Figures 1-5 The present invention provides an embodiment of a low-dust heat-sealing and cutting integrated device for cleanrooms, comprising a base plate 1, wherein a first conveyor belt 2 and a second conveyor belt 8 are provided inside the base plate 1. The second conveyor belt 8 is used to receive the packaging bags formed after heat sealing and cutting, and to smoothly transport the finished products to the next production process, thereby avoiding the inefficiency or pollution problems caused by manual transfer of finished products, and ensuring the smoothness and cleanliness of finished product transportation. A second fixed frame 20 is fixedly connected to the inner wall of the base plate 1. The first conveyor belt 2 is used to receive the film output from the unwinding roller 3 and smoothly transport the film after height adjustment to the working range of the second fixed frame 20. This achieves a smooth connection between the unwinding stage and the heat sealing and cutting stage, and avoids the film from shifting or wrinkling during the transportation process, thus ensuring the accuracy of subsequent heat sealing and cutting. The second fixed frame 20 is equipped with a heat sealing strip 23 and a cutter 25. A first fixed frame 4 is fixedly connected to the upper surface of the base plate 1. A sleeve 14 is slidably connected to the inner wall of the first fixed frame 4. The unwinding roller 3 is rotatably connected to the inner wall of the sleeve 14. The unwinding roller 3 is used to install the film to be processed and can rotate freely in the sleeve 14 to ensure that the film can be output smoothly during the production process. An adjustment component is provided on the outer wall of the first fixed frame 4. The adjustment assembly includes a slide rail 15, a sliding block 16, and a lead screw 17. The outer wall of the slide rail 15 is fixedly connected to the outer wall of the fixed frame 4. The inner wall of the sliding block 16 is slidably connected to the outer wall of the slide rail 15. The slide rail 15 provides a precise track for the sliding of the sliding block 16, restricting the sliding block 16 to move only in the vertical direction, avoiding the sliding block 16 from deviating and causing misalignment of the height adjustment of the unwinding roller 3, and ensuring the stability and accuracy of the height adjustment of the unwinding roller 3. The outer wall of the lead screw 17 is threadedly connected to the inner wall of the sliding block 16. A handwheel 18 is fixedly connected to the outer wall of the lead screw 17. The lead screw 17 can rotate under the drive of the handwheel 18, converting the rotational motion of the handwheel 18 into the linear motion of the sliding block 16 along the slide rail 15. A cylinder 19 is fixedly connected to the inner wall of the fixed frame 20. A connecting block 21 is fixedly connected to the output end of the cylinder 19. A buffer assembly is provided on the outer wall of the connecting block 21. The buffer assembly includes a buffer block 1 22 and a buffer block 27. The upper end of the buffer block 1 22 is fixedly connected to the outer wall of the connecting block 21, and the lower end of the buffer block 1 22 is fixedly connected to the upper surface of the heat sealing strip 23. When the heat sealing strip 23 is applied and heat-sealed, the buffer block 1 22 is deformed by compression, which can effectively absorb the impact force generated by the heat sealing strip 23 pressing down, avoid excessive heat sealing pressure leading to film damage or over-heat sealing, and ensure heat sealing quality. The upper end of the buffer block 27 is fixedly connected to the outer wall of the connecting block 21, and the lower end of the buffer block 27 is fixedly connected to a sliding block 26. The outer wall of sliding block 26 is slidably connected to the inner wall of connecting block 21. When the cutter 25 is cutting, sliding block 26 can move down with the cutter 25 to squeeze buffer block 27, transferring the cutting impact force to buffer block 27. The lower surface of sliding block 26 is fixedly connected to the outer wall of cutter 25. A base 24 is provided below cutter 25. When cutter 25 is cutting, buffer block 27 is deformed by the squeezing of sliding block 26, which can absorb the rigid collision force generated when cutter 25 and base 24 are in groove, preventing cutter 25 from being damaged by collision, while ensuring a flat cut and extending the service life of cutter 25. The outer wall of base 24 is fixedly connected to the inner wall of fixed frame 20.

[0028] Specifically, the base plate 1 integrates conveyor belt 1 2 and conveyor belt 2 8. Conveyor belt 1 2 is responsible for receiving the film output from the unwinding roller 3 and smoothly conveying the film after height adjustment to the working range of the fixed frame 20, avoiding film deviation or wrinkles during conveying, laying the foundation for subsequent heat sealing and cutting accuracy. Conveyor belt 2 8, after heat sealing and cutting, receives the formed packaging bags and conveys them to the next process without manual transfer, which improves conveying efficiency and avoids finished product contamination caused by human contact, ensuring clean production requirements. The fixed frame 20 fixed on the inner wall of the base plate 1 is the core area of ​​heat sealing and cutting. It is equipped with heat sealing strip 23, cutter 25 and cylinder 19. Cylinder 19 drives connecting block 21 to provide power for heat sealing and cutting. The fixed frame 1 4 fixed on the upper surface of the base plate 1 has a sleeve 14 slidably connected to its inner wall. The unwinding roller 3 is rotatably connected to the inner wall of the sleeve 14. The unwinding roller 3 is used to install the film to be processed and can rotate freely to ensure smooth film output. The outer wall of the fixed frame 14 is equipped with an adjustment component. The slide rail 15 provides a vertical sliding track for the sliding block 16 to prevent deviation. The operator turns the handwheel 18 to drive the lead screw 17 to rotate, converting the rotational motion into the linear motion of the sliding block 16, which in turn drives the sleeve 14 and the unwinding roller 3 to adjust the height, solving the problem of film loosening and wrinkling caused by the initial low height of the unwinding roller 3. The outer wall of the connecting block 21 is equipped with a buffer component. The buffer block 12 fixes the connecting block 21 and the heat sealing strip 23. During heat sealing, it absorbs the impact force due to the compression deformation, preventing the film from being damaged due to excessive heat sealing pressure or over-heat sealing. The buffer block 27 fixes the connecting block 21 and the sliding block 26. The sliding block 26 is connected to the cutter 25. During cutting, the sliding block 26 squeezes the buffer block 27, absorbing the rigid collision force of the cutter 25 and the groove of the base 24, preventing damage to the cutter 25 and ensuring a flat cut.

[0029] Reference Figure 2 , Figure 4 and Figure 6 A dustproof plate 6 is fixedly connected to the upper surface of the base plate 1. A symmetrical baffle 5 is fixedly connected to the inner wall of the dustproof plate 6. The baffle 5 can initially block the generated dust during the heat sealing and cutting process, preventing the dust from directly spreading to the cleanroom environment. The dustproof plate 6 is used to accommodate the symmetrical baffle 5, forming an initial dust barrier in the heat sealing and cutting area. Together with the baffle 5, it blocks the spread of dust and provides an installation support for the dust suction port of the pipe 7, ensuring that the dust can be effectively guided to the dust suction channel. The inner wall of the dustproof plate 6 is fixedly connected to a symmetrical pipe 7. The outer wall of the pipe 7 is fixedly connected to a collection box 9. A fan 13 is installed on one side of the outer wall of the collection box 9. Under the negative pressure generated by the fan 13, the pipe 7 sucks the dust initially blocked by the baffle 5 into the collection box 9, realizing the transportation of dust from the generation area to the collection area. The output end of the fan 13 is fixedly connected to a pipe 12. The outer wall of the pipe 12 is fixedly connected to the inner wall of the collection box 9. The inner wall of the collection box 9 is slidably connected to a sliding box 10. The inner wall of the sliding box 10 is fixedly connected to a filter plate 29. The surface of the filter plate 29 has holes of a specific diameter, which can filter larger particles in the dust sucked in from the pipe 7 and prevent large dust particles from clogging the pipe 12. The collection box 9 is divided into two areas: sliding box 10 and sliding box 2 11. This provides space for the graded filtration and classified collection of dust, while preventing secondary diffusion of dust during collection. It also facilitates the centralized treatment of dust in the future. A dust cover 28 is fixedly connected to the inner wall of sliding box 2 11. The dust cover 28 can prevent dust from entering the fan 13 with the airflow, thus avoiding dust accumulation inside the fan 13 and causing fan 13 failure, and ensuring the stable operation of the fan 13. Sliding box 2 11 is located below sliding box 10.

[0030] Specifically, the dustproof plate 6 fixed on the upper surface of the base plate 1 is a key structure for dust control. Its inner wall is fixed with symmetrical baffles 5 and pipe 7. The baffles 5 initially block the spread of dust during the heat sealing and cutting process, preventing dust from directly polluting the cleanroom environment. The dustproof plate 6 provides installation support for the baffles 5 and pipe 7, forming an initial dust barrier in the heat sealing and cutting area. At the same time, it guides the dust to gather towards pipe 7. The other end of pipe 7 is fixedly connected to the collection box 9. A fan 13 is installed on one side of the collection box 9. The output end of the fan 13 is fixedly connected to pipe 12. After the fan 13 is started, a negative pressure is formed through pipe 7 and pipe 12, which draws the dust blocked by the baffle 5 into the collection box 9. Inside the collection box 9, sliding box 10 and sliding box 21 located below it are slidably connected. The filter plate 29 fixed on the inner wall of sliding box 10 filters larger particles in the dust through specific aperture holes on its surface, preventing large dust particles from clogging pipe 22 or affecting subsequent processing. Sliding box 21 is used to collect the filtered fine dust, realizing the graded collection of dust, which is convenient for subsequent targeted treatment. The dust cover 28 fixed on the inner wall of sliding box 21 can prevent dust from entering the fan 13 with the airflow, avoiding dust accumulation that may cause the fan 13 to malfunction and ensuring the stable operation of the dust collection structure.

[0031] Working principle: When production is carried out in a clean room, the film to be processed is first installed on the unwinding roller 3. The operator turns the handwheel 18, which drives the lead screw 17 to rotate. The lead screw 17 drives the sliding block 16 to slide along the slide rail 15, which in turn drives the sleeve 14 to move synchronously, realizing the vertical height adjustment of the unwinding roller 3. The unwinding roller 3 can rotate freely within the sleeve 14 to ensure smooth film output. This avoids problems caused by the initial height of the unwinding roller 3 being too low. If the height is insufficient, the path of the film after output from the unwinding roller 3 will be too long, which may easily lead to local loosening and wrinkles, resulting in inconsistent tension in the subsequent heat sealing and cutting process, affecting the processing accuracy. Next, the heat sealing and cutting process begins. After height adjustment, the film is smoothly conveyed to the range of the fixed frame 20 via conveyor belt 2. The cylinder 19 is activated, and the output end of the cylinder 19 drives the connecting block 21 to press down. Simultaneously, the connecting block 21 drives the symmetrical heat sealing strips 23 to move down, so that the heat sealing strips 23 are in contact with the base 24 below, completing the heat sealing operation of the film. During this process, the buffer block 22 on the heat sealing strip 23 is deformed by compression, which can effectively absorb the impact force when the heat sealing strip 23 is pressed down, avoiding excessive heat sealing pressure that could cause the film to break or over-heat seal. After the heat sealing is completed, the cylinder 19 continues to drive the connecting block 21 to press down, so that the centrally located cutter 25 precisely matches the groove in the base 24 to cut the heat-sealed film. At this time, the sliding block 26 on the cutter 25 squeezes the buffer block 27. The deformation of the buffer block 27 buffers the cutting impact force, preventing the cutter 25 from being damaged by rigid collision, while ensuring a smooth cut. Finally, the finished product is conveyed and the dust is treated. The packaging bags formed after heat sealing and cutting are conveyed to the next process via conveyor belt 28. The dust generated during the heat sealing and cutting process is first initially blocked by the symmetrical baffles 5 inside the dustproof plate 6 to prevent the dust from spreading to the cleanroom environment. Then, the fan 13 is started. With the cooperation of pipe 212 and pipe 17, a negative pressure is generated to suck the dust blocked by the baffles 5 into the collection box 9. The dust first enters the sliding box 10 and is filtered by the filter plate 29 inside the box to filter larger dust particles and prevent them from clogging subsequent pipes or components. The fine dust after filtration enters the sliding box 21 through the holes on the filter plate 29 to achieve classified collection and subsequent processing. In addition, the dust cover 28 can effectively prevent dust from entering the fan 13 and prevent the fan 13 from malfunctioning due to dust accumulation, thus ensuring the stable operation of the equipment.
