Description

Technical Field

[0001] This invention belongs to the technical field of granulator equipment, and in particular relates to a sight glass mounting device for a dry granulator. Background Technology

[0002] In standard configurations, the front door sight glass of the dry granulator is made of tempered glass, which effectively avoids the problems of aging and yellowing caused by the aging of the conventional acrylic sight glass, resulting in a simpler and more elegant product appearance.

[0003] However, the sight glasses structure of dry-process machines on the market is currently an embedded structure. The embedded sight glass structure involves welding the sight glass seat to the front cover panel first, and then milling grooves to embed the sight glass into the sight glass seat. This type of structure has a complex processing technology and requires welding and polishing operations, resulting in high production costs and unsatisfactory sealing effects. There are always gaps in the embedded position of the sight glass, which can easily cause dust accumulation. The sight glass needs to be removed and cleaned every time the machine is stopped for cleaning, which is a lot of work for the operators and can easily scratch or damage the sight glass. Summary of the Invention

[0004] The purpose of this invention is to provide a sight glass installation device for a dry granulation machine. By first installing two inner pressure plates, the inner pressure plates can not only help support the glass, but also release the brakes on the rectangular blocks and the rotating shaft. While the rotating shaft is rotating, the rectangular rods and rectangular holes can be engaged, and the glass can be temporarily pressed down by four rectangular plates, which facilitates the installation of the outer pressure plates from the outside. After installation, the four outer pressure plates can be reset for future use, thus solving the existing technical problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] A sight glass mounting device for a dry granulator includes: a frame and glass, wherein the glass is disposed inside the frame, and grooves are provided on the top inner wall and the bottom inner wall of the frame, and fixing strips are fixedly connected to the top inner wall and the bottom inner wall of the frame, and there is a gap between the fixing strips and the grooves.

[0007] Two inner pressure plates and two outer pressure plates, the two outer pressure plates are located on one side of the glass and the two inner pressure plates are located on the other side of the glass, and the inner pressure plates and outer pressure plates are fixedly connected by a connecting assembly;

[0008] Each of the two fixing strips has a mounting groove on its opposite side, and a fixing component for fixing the inner pressure plate is provided inside the mounting groove.

[0009] The frame has four symmetrical pivots running through one side, and the outer wall of each pivot is provided with a clamping assembly for pressing the glass.

[0010] Optionally, the connecting assembly includes two rectangular bars that are fixedly connected to the outer pressure plate and the inner pressure plate on their respective sides. The rectangular bars have threaded grooves inside. Two screws are symmetrically arranged and threaded through one side of the outer pressure plate. The screws cooperate with the threaded grooves. The height of the inner pressure plate is greater than the height of the outer pressure plate.

[0011] Optionally, the fixing component includes a rectangular block slidably connected to the inner wall of the mounting groove, a rectangular rod fixedly connected to one side of the rectangular block, a rectangular hole for cooperating with the rectangular rod on one side of the fixing strip, a second spring fixedly connected between one side of the rectangular block and one side of the inner wall of the mounting groove, the second spring being sleeved on the rectangular rod, and two symmetrically arranged slots on one side of the inner pressure plate engaging with the rectangular rod.

[0012] Optionally, the clamping assembly includes a rotating plate fixedly sleeved on the outer wall of the rotating shaft, a sliding rod slidably passing through the inner wall of the rotating plate, a limiting plate fixedly connected to one end of the sliding rod, a tension spring fixedly connected between one side of the limiting plate and one side of the rotating plate, a rectangular plate fixedly connected to the other end of the sliding rod, and a third rubber pad fixedly connected to one side of the rectangular plate.

[0013] Optionally, a sliding plate is slidably connected to the inner wall of the groove, a second rectangular piece is fixedly connected to the bottom of the sliding plate, the second rectangular piece is used in conjunction with the inner pressure plate, a first rectangular piece is fixedly connected to the bottom of the sliding plate, two symmetrically arranged positioning rods are fixedly connected to the bottom of the first rectangular piece, two symmetrically arranged positioning grooves are opened on the top of the rectangular block, the positioning grooves are engaged with the positioning rods, and the same first spring is fixedly connected between the top of the sliding plate and the top inner wall of the groove.

[0014] Optionally, a semi-circular plate is fixedly connected to one end of the rotating shaft, and a convex plate is fixedly connected to one side of the rectangular block. The semi-circular plate and the convex plate are used in conjunction.

[0015] Optionally, a first rubber pad is provided at the bottom of the rectangular strip.

[0016] Optionally, a second rubber pad is provided on the side of the outer pressure plate and the inner pressure plate that are close to each other.

[0017] The embodiments of the present invention have the following beneficial effects:

[0018] 1. When installing the glass, the two inner pressure plates can be inserted into the groove first. At this time, the inner pressure plates push the second rectangular piece located above to move vertically upward. The second rectangular piece drives the sliding plate to move vertically upward. The sliding plate drives the first rectangular piece to move vertically upward. The first rectangular piece drives the positioning rod to move vertically upward. The positioning rod is no longer engaged with the positioning groove, releasing the braking state of the rectangular block.

[0019] 2. At the same time, the rotating shaft can also rotate. Since the gap between the inner wall of one side of the groove and the side of the fixing strip is matched with the inner pressure plate, the inner pressure plate can be locked. After the two inner pressure plates at the rear are installed, the glass can be placed on the two inner pressure plates. Rotate the four rotating shafts, the rotating shafts drive the rotating plates to rotate, the rotating plates drive the rectangular plates to rotate, and the rectangular plates move to one side of the glass.

[0020] 3. At this time, the limiting plate moves laterally under the tension of the tension spring. The limiting plate drives the sliding rod to move laterally towards the glass. The sliding rod drives the rectangular plate and the third rubber pad to move laterally towards the glass. The four rectangular plates can press the glass tightly against one side of the two inner pressure plates.

[0021] 4. As the shaft rotates, it drives the semicircular plate to rotate. The semicircular plate pushes the convex plate to move laterally. The convex plate drives the rectangular block to move laterally. The rectangular block pushes the rectangular rod to move laterally and squeezes the second spring. At this time, the rectangular rod passes through the rectangular hole and engages with the slot, which can ensure the stability of the inner pressure plate and prevent the inner pressure plate from falling off. At this time, the outer pressure plate can be placed on one side of the glass so that the two rectangular strips are close together. At this time, the fixing strip is located above the rectangular strip and the glass is located below the rectangular strip. Screw the screw into the threaded groove so that the outer pressure plate and the inner pressure plate are close together, which can complete the fixing of the glass.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The sliding rod 16 drives the rectangular plate 5 and the third rubber pad 14 to move laterally closer to the glass 2. The four rectangular plates 5 can press the glass 2 tightly against one side of the two inner pressure plates 8. While the rotating shaft 18 is rotating, it drives the semi-circular plate 30 to rotate. The semi-circular plate 30 pushes the convex plate 29 to move laterally. The convex plate 29 drives the rectangular block 27 to move laterally. The rectangular block 27 pushes the rectangular rod 32 to move laterally and squeezes the second spring 26.

At this time, the outer pressure plate 3 can be placed on one side of the glass 2 so that the two rectangular strips 11 are close together. At this time, the fixing strip 7 is located above the rectangular strip 11 and the glass 2 is located below the rectangular strip 11.
