Description

Technical Field

[0001] This utility model relates to the field of heat sealing equipment technology, specifically a microporous plate heat sealing equipment with a rocker arm lifting structure. Background Technology

[0002] Microplate heat sealers are widely used in fields such as biomedicine and chemical testing to seal microplates to prevent sample evaporation, contamination, or cross-reaction.

[0003] Traditional microporous plate heat sealing equipment struggles to flexibly adjust the relative height between the microporous plate and the heating block when heat-sealing microporous plates of different specifications. Due to the diverse specifications, thicknesses, and dimensions of microporous plates, the inability to effectively adjust the height can lead to poor contact between the heating block and the microporous plate, affecting the heat sealing quality. For example, with thinner microporous plates, excessive distance between the heating block and the plate results in insufficient heat transfer, failing to achieve the desired heat sealing effect; conversely, with thicker microporous plates, insufficient distance can cause the heating block to apply excessive pressure, damaging the microporous plate or affecting the uniformity of the heat sealing. Utility Model Content

[0004] The purpose of this invention is to provide a micro-perforated plate heat sealing instrument with a rocker arm lifting structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microporous plate heat sealer with a rocker arm lifting structure, comprising a base, a housing fixedly mounted on the top of the base, a top cover fixedly mounted on the top of the housing, and a heating block fixedly mounted on the bottom of the top cover, and further comprising: A storage plate for storing microporous plates is installed on a housing, and the housing is equipped with an adjustment component for adjusting the height of the storage plate; A reset component mounted on the housing to enable the adjustment assembly to automatically reset.

[0015] 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.

[0016] Please see Figure 1-6 As shown, a microporous plate heat sealer with a rocker arm lifting structure includes a base 1, a housing 2 fixedly mounted on the top of the base 1, a top cover 3 fixedly mounted on the top of the housing 2, and a heating block 4 fixedly mounted on the bottom of the top cover 3. It also includes: a storage plate 5 mounted on the housing 2 for storing microporous plates; an adjustment component 6 mounted on the housing 2 for adjusting the height of the storage plate 5; and a reset component 11 mounted on the housing 2 to enable the adjustment component 6 to automatically reset. The heating block 4 is connected to a heating module via a wire (the heating module is electrically connected to a control terminal via a wire for controlling the operation of the aforementioned electrical equipment; the above should be considered prior art, and the specific structure, working principle, and possible control methods and spatial arrangements of these technical features can be conventionally selected in the field; this technical solution will not be further elaborated in detail).

[0017] During the heat sealing process of the microporous plate, the microporous plate is placed on the upper part of the storage plate 5. The height of the storage plate 5 is adjusted by the adjusting component 6 so that the storage plate 5 and the microporous plate move up to contact the heating block 4 for heat sealing. After the heat sealing process is completed, the reset component 11 causes the adjusting component 6 to drive the storage plate 5 to fall and reset.

[0018] Based on the above implementation scheme, the adjustment component 6 includes push rods 61 and rotating rods 62 rotatably mounted on both sides of the housing 2. A connecting shaft 63 is fixedly mounted on the rotating rod 62, and a transmission rod 64 is rotatably mounted on the connecting shaft 63. A handle 65 is fixedly mounted between the two push rods 61. A limiting plate 66 is fixedly mounted on the bottom of the storage plate 5. The transmission rod 64 slides in the limiting plate 66. A limiting groove 12 is opened on the top of the push rod 61. The end of the push rod 61 is elliptical. The bottom of the connecting shaft 63 is tangent to the outer side of the elliptical end of the push rod 61. The transmission rod 64 is rotatably mounted between the two connecting shafts 63, and the handle 65 is fixedly mounted between the two push rods 61.

[0019] Storage plate 5 is initially set as Figure 1In the indicated state, when adjusting the height of the storage plate 5, the handle 65 is pulled downwards, and the elliptical end of the push rod 61 rotates clockwise, causing the connecting shaft 63 and the rotating rod 62 to rotate counterclockwise synchronously. While rotating, the rotating rod 62 lifts the transmission rod 64. When the transmission rod 64 is lifted, it slides in the limiting plate 66, raising the storage plate 5. The storage plate 5 causes the microporous plate placed on it to move upwards and contact the heating block 4, performing heat sealing treatment on the microporous plate. After the heat sealing treatment of the microporous plate is completed, the push rod 61 is pushed upwards, and the connecting shaft 63 moves in the opposite direction, lowering the storage plate 5.

[0020] Based on the above implementation scheme, a sliding groove 7 is provided on the storage plate 5, and a sliding rail 8 is fixedly installed on the outer shell 2.

[0021] When the storage plate 5 moves, it slides on the slide rail 8 through the slide groove 7 on one side, which limits the movement of the storage plate 5 and allows the storage plate 5 to move vertically up and down on the outer shell 2.

[0022] Based on the above implementation scheme, a slot is provided on the outer shell 2, and the reset assembly 11 includes a connecting block 111 that is slidably installed in the slot, a roller 112 that is rotatably installed on the connecting block 111, and a spring 113 that is fixedly installed between the top of the connecting block 111 and the slot.

[0023] When the connecting shaft 63 rotates, it pushes the roller 112 and the connecting block 111 to move in the slot. When the connecting shaft 63 moves upward, it pushes the roller 112 and the connecting block 111 upward, at which time the spring 113 is compressed. When the connecting shaft 63 moves downward, the spring 113 loses pressure and resets, causing the roller 112 and the connecting block 111 to move downward, pushing the connecting shaft 63 to move down to its original position, preparing for the next operation.

[0024] Based on the above implementation plan, and referring to Figure 1 and Figure 5 Two symmetrical fixing strips 9 are fixedly installed on the top of the base 1, and the fixing strips 9 have slots 10.

[0025] When the connecting shaft 63 moves to Figure 1 After reaching the indicated state, the connecting shaft 63 is stored in the slot 10, causing the storage plate 5 to move down onto the base 1.
