Description

Technical Field

[0001] The utility model relates to the technical field of spherical shot blasting machines, in particular to a rodless cylinder discharging device of a spherical shot blasting machine. Background Art

[0002] Spherical shot blasting machine (rounding device) is a centrifugal pill making machine. It uses a high-speed turntable to generate centrifugal force to make the material spherical. It is an ideal equipment for preparing capsules and Chinese herbal pills. Its working principle is that the pellets are rounded and smoothed in a three-dimensional spiral rolling due to the thrust of the rack on the centrifugal turntable in the rotating cylinder, the centrifugal force of the turntable, and the friction between the cylinder wall and the pellets. When discharging, the cylinder is used to directly drive the discharge door to open, so that the material can come out from the discharge port.

[0003] Patent CN201220136718.X discloses a discharge controller for a spherical shot blasting machine, and specifically discloses that "it includes a discharge cylinder 1 and a discharge inclined cylinder 2. The discharge cylinder 1 is installed on the outer wall of the spherical shot blasting machine and is connected to the interior of the spherical shot blasting machine. The discharge inclined cylinder 2 is fixedly installed at the lower end of the discharge cylinder 1 and is connected to the interior of the discharge inclined cylinder 2. It also includes an air pump 3, a valve block 4, and an air compressor 5. The air pump 3 is fixedly connected to the other side of the discharge cylinder 1. The valve block 4 is inside the discharge cylinder 1 and is fixedly connected to the connecting rod of the air pump 3. The air pump 3 is connected to the air compressor 5. The shape of the valve block 4 corresponds to the cross-sectional shape of the inner wall of the discharge cylinder 1." The discharge structure of the existing ball shot blasting machine is as described above. The cylinder rod of the cylinder (i.e. the above-mentioned air pump) is inserted into the sealing door of the discharge sealing cover (i.e. the above-mentioned discharge cylinder), and the discharge door (i.e. the above-mentioned valve block) connected by the cylinder rod is driven to open.

[0004] The cylinder rod of the cylinder will have an oil film, which will become thicker and thicker with use. When discharging materials, the particles and dust will stick to the cylinder rod. With the push of the cylinder and the vibration of the machine, these particles and dust with oil will enter the material. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a rodless cylinder discharging device for a spherical shot blasting machine to reduce dust pollution of materials.

[0006] The utility model is achieved in this way:

[0007] A rodless cylinder discharging device for a spherical shot blasting machine comprises a push rod connected to a discharging door, wherein the push rod is driven by the rodless cylinder.

[0008] Furthermore, the push rod is connected to the rodless cylinder via a connecting block.

[0009] Furthermore, the connecting block is an L-shaped connecting block, one end of the L-shape is connected to the slider on the rodless cylinder, and the other end is sleeved on the outside of the push rod.

[0010] Furthermore, a sealing buffer block is sleeved on the end of the push rod connected to the discharge door.

[0011] Furthermore, the sealing buffer block is a silicone pad.

[0012] Furthermore, a sealing cover is provided on the outside of the rodless cylinder.

[0013] The advantages of the utility model are:

[0014] The utility model adopts a mode in which the cylinder and the push rod are separated, and the rodless cylinder drives the push rod to drive the discharge door. In this way, the push rod will not be stained with oil, reducing dust pollution of the material. A sealing buffer block is arranged on the push rod to play a buffering and sealing role. A sealing cover is set outside the cylinder to reduce dust pollution of the cylinder track. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the description of the present invention, it should be understood that the description indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The technical solution of the utility model is as follows:

[0023] See also Figure 1 and Figure 2 As shown, a rodless cylinder discharging device of a ball shot blasting machine of the utility model comprises a push rod 1 connected to a discharging door 100 , and the push rod 1 is driven by a rodless cylinder 2 .

[0024] The push rod is driven by the rodless cylinder 2 to drive the discharge door. The rodless cylinder is fixed on the sealing door 200 through a fixed bracket (not shown). The push rod 1 is connected to the rodless cylinder 2 through a connecting block 3.

[0025] In a specific embodiment, the connecting block 3 is an L-shaped connecting block, one end of which is connected to the slider 21 on the rodless cylinder 2 and is locked by bolts. The other end is sleeved on the outside of the push rod 1 and is locked by bolts inserted from one side of the connecting block. Figure 3 shown.

[0026] In a specific embodiment, the push rod 1 is sleeved with a sealing buffer block 4 at the end connected to the discharge door 100. In the original discharge device, the cylinder rod of the cylinder penetrates the sealing door of the discharge sealing cover, that is, the cylinder rod and the sealing door are matched with each other, and there is a certain gap. After multiple discharges, dust will escape through the gap and adhere to the cylinder rod. By sleeved with the sealing buffer block 4 at the end of the push rod 1, when the push rod 1 drives the discharge door 100 to open, the sealing buffer block 4 is located between the discharge door 100 and the sealing door 200, which plays the role of buffering the discharge door and sealing the sealing door.

[0027] The sealing buffer block 4 can be a silicone pad or other pads with buffering and sealing functions. Its shape is cylindrical or other suitable shapes.

[0028] In a specific embodiment, a sealing cover 5 is provided outside the rodless cylinder 2. The sealing cover 5 is set outside the cylinder to reduce dust pollution of the cylinder track. The sealing cover 5 is set outside the sealing door 200.

[0029] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
