Description
Technical Field
[0001] The utility model relates to the technical field of film sealing equipment, in particular to a film pressing device used in a film sealing machine. Background Art
[0002] The main function of the coverslip machine is to fix biological or non-biological materials on a carrier to facilitate further processing. It is also used in biological laboratories to seal experimental samples in specific containers or equipment to maintain the activity of the samples or prevent the samples from being contaminated.
[0003] Most of the existing sealing devices on the market use a rigid structure with hollow sides pressed tightly. When sealing, this structure uses rigid contact and the middle of the cover glass is empty, resulting in poor stability of the gap between the cover glass and the slide during the sealing process. Bubbles will appear after sealing, which affects the sealing quality. Therefore, we designed a pressing device for the sealing machine. Utility Model Content
[0004] The utility model aims to provide a tablet pressing device for a tablet sealing machine, which can reduce the risk of tablet breakage, and at the same time has better and more stable tablet sealing quality and fewer bubbles, thereby solving the problems raised in the background technology.

A guide hole is provided on the base plate, and a sliding rod is slidably connected in the guide hole. The top end of the sliding rod is fixedly connected to the rotating pressure head, and the bottom end of the sliding rod is fixedly connected to a limiting block.
[0007] Through the above technical solution, the present application starts the rotating motor to drive the rocker arm to rotate. Since the rocker arm is limited by the fixed block, the rocker arm swings in the movable groove, and at the same time drives the rotary pressure head to swing on the bottom plate. At this time, the sliding rod in the rotary pressure head slides in the guide hole. When the entire utility model moves downward to press the tablet, the negative pressure suction cup on the rotary pressure head sucks up the cover glass, and when the cover glass moves downward to press the tablet, the cover glass and the slide are always kept in a certain pressure contact by the sealing buffer rubber sleeve, thereby ensuring better and more stable sealing quality and fewer bubbles. At the same time, the arc movement of the rotary pressure head can make the front of the sealing buffer rubber sleeve fully contact with the cover glass, so that the cover glass is subjected to more uniform force during the sealing process, reducing the risk of broken tablets and reducing sealing bubbles.
[0008] Preferably, the lower surface of the sealing buffer rubber sleeve is designed to be arc-shaped, and the number of the negative pressure suction cups is two and they are distributed on the left and right sides of the sealing buffer rubber sleeve.
[0009] Through the above technical solution, the arc-shaped sealing buffer sleeve of the present application is always in flexible contact with the cover glass during the sealing process, thereby ensuring that pressure is maintained between the cover glass and the slide, ensuring the sealing quality, and can cooperate with the arc movement of the rotating pressure head to perform comprehensive pressing.
[0010] Preferably, the shape of the movable groove is adapted to the shape of the rocker arm, and the shape of the movable groove is adapted to the shape of the guide hole.
[0011] Through the above technical solution, the rocker arm of the present application will drive the rotary pressure head to move under the action of the rotating motor. The rotary pressure head will remain stable during the movement due to the limitation of the sliding rod, thereby ensuring the quality of the sealing film.
[0012] Preferably, an induction sensor is fixedly mounted on the front side of the outer frame.
[0013] Through the above technical solution, the inductive sensor of the present application ensures that the pressure remains stable when pressing and sealing the tablet.
[0014] Preferably, the guide holes are arc-shaped holes, and there are two guide holes distributed left and right on the bottom plate.
[0015] Through the above technical solution, the shape of the guide hole of the present application can match the moving trajectory of the rocker arm, that is, the moving trajectory of the rotary pressure head is adapted to the guide hole.
[0016] Preferably, the limiting block contacts the lower surface of the bottom plate, and the diameter of the sliding rod is adapted to the inner diameter of the guide hole.
[0017] By adopting the above technical solution, the beneficial effects of the utility model are:
[0018] 1. The pressing device for the sealing machine adds a specific arc-shaped sealing buffer rubber sleeve to the bottom of the rotating pressure head, which is always in flexible contact with the cover glass during the pressing and sealing process, so that the cover glass and the slide always maintain a certain pressure contact, thereby producing higher quality tissue slides. At the same time, during the sealing process, the cover glass is subjected to more uniform force, reducing the risk of breakage and sealing bubbles, thereby solving the problems raised in the background technology.

The top end of the slide rod 12 is fixedly connected to the rotating pressure head 3, and the bottom end of the slide rod 12 is fixedly connected to the limit block 13.
[0027] Through the above technical solution, the present application starts the rotating motor 6 to drive the rocker arm 9 to rotate. Since the rocker arm 9 is limited by the fixed block 8, the rocker arm 9 swings in the movable groove 7, and at the same time drives the rotary pressure head 3 to swing on the bottom plate 2. At this time, the slide rod 12 in the rotary pressure head 3 slides in the guide hole 11. When the entire utility model moves downward to press the film, the cover glass is sucked up by the negative pressure suction cup 5 on the rotary pressure head 3, and when the cover glass moves downward to press the film, the cover glass and the slide are always kept in a certain pressure contact by the action of the sealing buffer rubber sleeve 4, thereby ensuring better and more stable sealing quality and fewer bubbles. At the same time, the arc movement of the rotary pressure head 3 can make the front of the sealing buffer rubber sleeve 4 completely contact with the cover glass, so that the cover glass is subjected to more uniform force during the sealing process, reducing the risk of broken film and reducing sealing bubbles.
[0028] The lower surface of the sealing and buffering rubber sleeve 4 is designed to be arc-shaped, and there are two negative pressure suction cups 5 distributed on the left and right sides of the sealing and buffering rubber sleeve 4.
[0029] Through the above technical solution, the arc-shaped sealing buffer rubber sleeve 4 of the present application is always in flexible contact with the cover glass during the sealing process, thereby ensuring that pressure is maintained between the cover glass and the slide, ensuring the sealing quality, and can cooperate with the arc-shaped movement of the rotating pressure head 3 to perform comprehensive pressing.

[0031] Through the above technical solution, the rocker arm 9 of the present application will drive the rotary pressure head 3 to move under the action of the rotary motor 6. During the movement, the rotary pressure head 3 will remain stable due to the limitation of the slide bar 12, thereby ensuring the quality of the sealing film.
[0032] An induction sensor 14 is fixedly mounted on the front of the outer frame 1 .
[0033] Through the above technical solution, the inductive sensor 14 of the present application ensures that the pressure remains stable when the tablet is pressed and sealed.
[0034] The guide holes 11 are arc-shaped holes, and there are two guide holes 11 distributed on the left and right sides of the bottom plate 2 .
