Description

Technical Field

[0001] This utility model relates to the field of vacuum heat sealing technology, specifically to a sliding cover-type single-unit vacuum heat sealing machine. Background Technology

[0002] Vacuum heat sealing machines are mechanical devices used in the packaging industry, primarily for vacuum packaging of food, pharmaceuticals, electronic products, and other items. These machines complete both vacuuming and sealing in a single operation, ensuring the required vacuum level inside the packaging bag, thereby extending the product's shelf life and preventing oxidation or moisture absorption. Currently available single-unit vacuum heat sealing machines cannot meet the high vacuum requirements of the electronics and capacitor industry. Their covers are simply placed on the cavity, failing to achieve the necessary high vacuum levels. High-vacuum vacuum heat sealing machines, on the other hand, have more complex structures and are larger in size. Furthermore, the design for placing the heat sealing strip and samples results in low efficiency, and the manual pushing and pulling of the door for opening and closing is inefficient and inconvenient. Multi-layer, high-volume vacuum heat sealing machines are inferior to smaller vacuum heat sealing machines in terms of vacuum level, vacuum pumping speed, and cost-effectiveness; the latter are more suitable for experimental applications. Utility Model Content

[0003] Technical problem to be solved by the utility model

[0004] To address the technical problems of existing vacuum heat sealing machines failing to meet the high vacuum requirements of the electronic capacitor industry, and the need for manual pushing and pulling to open and close the door, which is inefficient and inconvenient, this utility model provides a sliding cover-type single-unit vacuum heat sealing machine. It can achieve a high vacuum level, and the opening and closing of the chamber door is controlled by a cylinder lifting mechanism, while the module drives the sliding motion, making it efficient and convenient. The cover plate has a sealing structure, further enhancing the vacuum level, making it suitable for experimental applications.

[0005] Technical solution

[0006] To solve the above problems, the technical solution provided by this utility model is as follows:

[0007] A sliding cover-type single-unit vacuum heat sealing machine includes a base frame; a cavity assembly including a single-unit box body with a heat sealing mechanism inside; a cover plate assembly including ball lifting rods and a cover plate body, the cover plate body being a sliding structure that slides to a position where it fits against the box body and its lower surface seals against the top surface of the box body; multiple ball lifting rods are provided, with balls at their top; the lower surface edge of the cover plate body has a sliding groove that slides with the balls; the ball lifting rods are connected to the output end of a ball lifting cylinder via a lifting adapter plate; and a sliding drive assembly including a movable frame connected to a linear guide rail, the movable frame being detachably connected to the cover plate body.

[0008] The base frame serves as the fundamental support for the entire machine, ensuring its stability and safety.

[0009] The cavity assembly consists of a single-unit box with an internal heat-sealing mechanism responsible for heating and sealing the packaging bag. The box design ensures good sealing during vacuuming to achieve the required high vacuum level.

[0010] The cover assembly includes a ball-bearing lifting rod and a cover body. The cover body employs a translational structure design, enabling it to accurately slide to a position where it fits snugly against the box, achieving a tight seal between the lower surface and the top surface of the box to reach the required high vacuum level. The balls at the top of the ball-bearing lifting rod slide against a groove on the lower edge of the cover body, ensuring stability during translation and guiding the cover body. The ball-bearing lifting rod is connected to a ball-bearing lifting cylinder via a lifting adapter plate, enabling automatic opening and closing of the cover, which is highly efficient and convenient.

[0011] The translation drive assembly includes a movable frame connected to a linear guide rail. This movable frame is detachably connected to the cover plate body, allowing the cover plate to move smoothly along a predetermined track, ensuring efficiency and convenience during operation. The detachable connection also allows the cover plate body to move vertically, forming a sealed cavity with the box to achieve the required high vacuum level.

[0012] Through the above design, this machine can not only achieve a high vacuum level, but also ensure the smooth operation of the cover plate throughout the entire operation, improving work efficiency and product quality. Due to its efficient and convenient operation and the high vacuum level it can achieve, this sliding cover-type single-unit vacuum heat sealing machine is ideal for laboratory research, sample testing, and small-batch production.

[0013] Optionally, the heat sealing mechanism includes a substrate holder, a pressure plate, an upper pressure plate, and a heating block. The substrate holder and the pressure plate press and fix the sample vertically. The upper pressure plate and the heating block are aligned with the heat sealing opening of the sample. The upper pressure plate is connected to a lifting cylinder.

[0014] The substrate holder is a platform for placing the sample to be packaged (usually a packaging bag). The substrate holder is kept flat to ensure sample stability. A clamping plate, located above the substrate holder, works together to clamp and secure the sample, ensuring it does not move during heat sealing and thus guaranteeing the effectiveness and quality of the heat seal. The upper pressure plate is aligned with the heating block and acts directly on the heat-sealing area of ​​the sample. The heating block is one of the core components of the heat sealing mechanism; it reaches the required temperature through electric heating to heat and seal the sample. The upper pressure plate moves up and down via a lifting cylinder. When heat sealing is required, the lifting cylinder drives the upper pressure plate downwards, bringing the heating block into contact with the sample and applying pressure to complete the heat sealing process. After completion, the lifting cylinder drives the upper pressure plate back to its initial position, ready for the next operation. The alignment of the upper pressure plate with the heating block ensures accurate application of heat to the sample's heat-sealing area each time. The use of the lifting cylinder automates the heat sealing process, improving work efficiency and reducing the need for manual intervention.

[0015] Optionally, the clamping plate is provided with a tightening hole, the substrate frame is provided with a threaded post, and the threaded post is fitted with a tightening element.

[0016] The clamping plate has several tightening holes for inserting threaded posts and tightening parts to secure the clamping plate to the substrate holder. Operation is simple and quick.

[0017] Alternatively, the tightening hole can be a waist-shaped hole.

[0018] The tightening holes on the pressure plate are designed as oblong holes, rather than traditional round holes. The long axis of the oblong hole allows the tightening element to move within a certain range, thus providing greater adjustment space.

[0019] Optionally, the upper pressure plate is connected to the lifting cylinder via a telescopic frame below, the lifting cylinder is fixedly installed, and an elastic pressure plate is provided below the upper pressure plate.

[0020] The lifting cylinder is fixedly installed and controls the extension and retraction of the telescopic frame via a pneumatic system, thereby moving the upper pressure plate up and down. The stroke and speed of the lifting cylinder can be precisely adjusted through the control system. The elastic pressure plate is located below the upper pressure plate and is in close contact with it. The elastic pressure plate is usually made of a material with a certain degree of elasticity.

[0021] Optionally, the lower surface of the cover body is provided with sealing rings distributed along its edges, and the sealing rings are adapted to seal the top surface of the box.

[0022] The sealing rings are installed on the lower edge of the cover body, distributed around the entire edge of the cover. The sealing rings are typically made of materials with good elasticity and high-temperature resistance, such as silicone rubber or fluororubber. When the lower surface of the cover body contacts the top surface of the housing, the sealing rings are compressed and deformed, forming a tight sealing interface. The elastic material of the sealing rings fills the tiny gaps between the cover body and the housing, ensuring that air cannot enter, thus achieving a high degree of vacuum.

[0023] Optionally, the movable frame is provided with a downward-facing groove block, and the upper surface of the cover plate body is provided with a locking block, which is adapted to engage with the groove block after the ball lifting rod is raised.

[0024] After the groove block and the locking block are engaged, the cover plate body can move with the moving frame. The cover plate also needs to move in the vertical direction to achieve a tight seal with the box body. Therefore, the locking part needs to be disengaged after it is moved into place. Hence, this detachable connection structure is designed.

[0025] Optionally, the groove of the recessed block is provided with a chamfered structure.

[0026] Because the groove of the recessed block has a chamfered structure, when the engaging block on the cover plate body approaches the recessed block, the chamfered structure can guide the engaging block to smoothly enter the groove. The guiding effect of the chamfered structure makes the engaging process smoother, reduces friction and collision between the engaging block and the recessed block, and improves the reliability and speed of engaging.

[0027] Optionally, the housing is connected to a vacuum pumping mechanism.

[0028] The vacuum pumping mechanism is used to create a vacuum.

[0029] Beneficial effects

[0030] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0031] It can achieve a high vacuum level, and the opening and closing of the chamber door is controlled by the cylinder lifting, while the module drives the translation, which is efficient and convenient. The cover plate has a sealing structure to improve the vacuum level, making it suitable for experimental applications. It compresses the vacuum chamber space, saves costs, improves the ultimate vacuum value to facilitate applications in more scenarios, and also improves the heat sealing stability.

[0041] Combined with appendix Figure 2 , 4The cavity assembly 2 includes a single-unit box 201, within which a heat-sealing mechanism is installed. The cavity assembly 2 is composed of the single-unit box 201, with a built-in heat-sealing mechanism responsible for heating and sealing the packaging bag. The design of the box 201 ensures good sealing during vacuuming to achieve the required high vacuum level. The heat-sealing mechanism includes a substrate holder 207, a pressure plate 202, an upper pressure plate 204, and a heating block. The substrate holder 207 and the pressure plate 202 press and fix the sample vertically, while the upper pressure plate 204 and the heating block align with the heat-sealing opening of the sample. The upper pressure plate 204 is connected to a lifting cylinder 209. In this embodiment, two rows of substrate holders 207 are provided. The substrate holders 207 are platforms for placing the samples to be packaged (usually packaging bags). The substrate holders 207 are kept flat to ensure the stability of sample placement. The pressure plate 202 is located above the substrate holders 207 and works together with the substrate holders 207 to clamp and fix the sample. The upper pressure plate 204 is aligned with the heating block and acts directly on the heat-sealing area of ​​the sample. The heating block reaches the required temperature through electric heating to heat and seal the sample. The upper pressure plate 204 is connected to a lifting cylinder 209 to move up and down. When heat sealing is required, the lifting cylinder 209 drives the upper pressure plate 204 downward, bringing the heating block into contact with the sample and applying pressure to complete the heat sealing process. After completion, the lifting cylinder 209 drives the upper pressure plate 204 back to its initial position, ready for the next operation. The alignment of the upper pressure plate 204 with the heating block ensures that each heat seal is applied accurately to the heat-sealing area of ​​the sample. The use of the lifting cylinder 209 automates the heat sealing process. Handles 205 are provided on both sides of the substrate holder 207.

[0042] The clamping plate 202 has tightening holes, and the substrate holder 207 has threaded posts. A tightening element 203 is fitted onto the threaded posts. The clamping plate 202 has several tightening holes for inserting the threaded posts, which, in conjunction with the tightening element 203, secure the clamping plate 202 to the substrate holder 207. Operation is simple and quick. The tightening holes are oblong. The tightening holes on the clamping plate 202 are designed as oblong holes, rather than traditional circular holes. The long axis of the oblong holes allows the tightening element 203 to move within a certain range, thus providing greater adjustment space.

[0043] The upper pressure plate 204 is connected to the lifting cylinder 209 via the lower telescopic frame 208. The lifting cylinder 209 is fixedly installed, and an elastic lifting plate 206 is located below the upper pressure plate 204. The lifting cylinder 209 is fixedly installed, and the telescopic frame 208 is controlled by a pneumatic system to move the upper pressure plate 204 up and down. The stroke and speed of the lifting cylinder 209 can be precisely adjusted by the control system. The elastic lifting plate 206 is located below the upper pressure plate 204 and is in close contact with it. The upper pressure plate 204 is elastically pressed, and the elastic lifting plate 206 is stably clamped using a spring and a EPDM soft pad. The EPDM soft pad is located on the lower surface of the elastic lifting plate 206.

[0044] Combined with appendix Figure 3 , 5 The cover assembly 3 includes a ball-bearing lifting rod 301 and a cover body 302. The cover body 302 has a translational structure and moves to a position where it is in contact with the box 201, sealing its lower surface with the top surface of the box 201. Multiple ball-bearing lifting rods 301 are provided, with balls at their top. The lower surface edge of the cover body 302 has a groove 304 that slides with the balls. The ball-bearing lifting rods 301 are connected to the output end of the ball-bearing lifting cylinder 306209 via a lifting adapter plate 305. The cover body 302's translational structure design allows it to accurately move to a position where it is in contact with the box 201, achieving a tight seal between its lower surface and the top surface of the box 201 to achieve the required high vacuum level. The balls at the top of the ball-bearing lifting rods 301 slide with the groove 304 on the lower surface edge of the cover body 302, ensuring stability during the translation process and guiding the cover body 302. The ball lifting rod 301 is connected to the ball lifting cylinder 306209 via the lifting adapter plate 305, realizing the automatic opening and closing function of the cover plate, which is efficient and convenient. The slide groove 304 is set at the bottom of the slider 303, and the slider 303 is fixed to the bottom surface of both sides of the cover plate body 302.

[0045] Combined with appendix Figure 1 The ball lifting rods 301 are arranged on both sides of the base plate 5. The two ball lifting rods 301 on one side near the movable frame 401 are fixed at a fixed height, while the other ball lifting rods 301 on the edge of the box 201 can be raised and lowered. The raiseable ball lifting rods 301 are arranged through the base plate 5.

[0046] Combined with appendix Figure 3 The box body 201 is connected to a vacuum mechanism 6. The ball lifting cylinder 306209 is fixed to the bottom of the base plate 5 through the cylinder fixing plate 307.

[0047] Combined with appendix Figure 5The lower surface of the cover body 302 is provided with sealing rings 309 distributed along its edges. The sealing rings 309 are fitted to and seal against the top surface of the housing 201. The sealing rings 309 are installed along the lower edge of the cover body 302, distributed around the entire edge of the cover. The sealing rings 309 are made of fluororubber. When the lower surface of the cover body 302 contacts the top surface of the housing 201, the sealing rings 309 are compressed and deformed, forming a tight sealing interface. The elastic material of the sealing rings 309 can fill the tiny gaps between the cover body 302 and the housing 201, ensuring that air cannot enter, thereby achieving a high degree of vacuum.

[0048] Combined with appendix Figure 4 The translation drive assembly 4 includes a movable frame 401 connected to a linear guide rail 405, and the movable frame 401 is detachably connected to the cover plate body 302. The translation drive assembly 4 includes a movable frame 401 connected to the linear guide rail 405, and the movable frame 401 is detachably connected to the cover plate body 302, allowing the cover plate to move smoothly along a predetermined track, ensuring efficiency and convenience during operation. The detachable connection allows the cover plate body 302 to move vertically, so as to form a sealed cavity with the box body 201 to achieve the required high vacuum level.

[0049] The movable frame 401 has a downward-facing recessed block 402, and the upper surface of the cover plate body 302 has a locking block 308. The locking block 308 and the recessed block 402 are matched and locked after the ball lifting rod 301 is raised. After the recessed block 402 and the locking block 308 are locked, the cover plate body 302 can move with the movable frame 401. However, the cover plate also needs to move in the vertical direction to achieve a tight seal with the box body 201. Therefore, the locking part needs to be disengaged after moving into place, hence this detachable connection structure. The groove of the recessed block 402 has a chamfered structure.

[0050] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
