Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a silica gel mixing machine. Background Art

[0002] Silicone mixing is to make the compounding agent evenly distributed in the raw rubber and make a mixed rubber. After mixing, the silicone and the compounding agent play a physical and chemical role at the same time, thus forming a new structure. The phase state of silicone at different temperatures is divided into elastic state, granular state, and plastic state. The change of silicone between the three states is reversible. If the temperature is lowered, the silicone in the plastic state can be restored to the elastic state. The shear force of the elastic state can make the filler disperse well. When the processing temperature is higher than 90℃, a part of the silicone is transformed into the plastic state, forming a state where the elastic state and the plastic state coexist, that is, the granular state. Because the compounding agent is granular, in order to better add it to the silicone, the raw rubber must be plasticized first. The purpose of plasticization is to improve its plasticity and fluidity. Mixing is to use the strong mechanical shearing effect of the rubber mixer.

[0003] Due to the high temperature of silica gel, there will usually be residues on the surface of the mixing roll set. When the mixing roll set cools down, the attachments on the surface are difficult to clean. Utility Model Content

[0004] In view of the problems existing in the background technology, the utility model provides a silicone mixing machine which is convenient for cleaning the attachments on the surface of the mixing roller group.

[0005] The technical solution of the utility model is as follows: a silica gel mixer, comprising a mixer body, on which a mixing roller group and a bidirectional ball screw are arranged, the mixing roller group and the bidirectional ball screw are arranged in parallel, and the connecting shaft of the mixing roller group is connected to the bidirectional ball screw through a transmission mechanism;

[0006] The bidirectional ball screw is provided with a ball nut, and a cleaning ring is detachably mounted on the ball nut. When the ball nut moves along the bidirectional ball screw, the cleaning ring can move along the mixing roller group.

[0007] In an optional embodiment, the transmission mechanism includes a first synchronous wheel connected to the mixing roller group and a second synchronous wheel fixed on the bidirectional ball screw, and the first synchronous wheel and the second synchronous wheel are connected by a synchronous belt transmission.

[0008] In an optional embodiment, the cleaning ring has two through holes, the mixing roller group is located in the two through holes of the cleaning ring respectively, and the through holes are coaxially arranged with the axial direction of the mixing roller group.

[0009] In an optional embodiment, when the cleaning ring moves along the mixing roller set, the inner surface of the cleaning ring contacts the surface of the mixing roller set.

[0010] In an optional embodiment, a connecting rod is provided on the cleaning ring, and a connecting plate is provided on the ball nut. At least a portion of the connecting rod passes through the connecting plate and is fixed to the connecting plate by a nut.

[0011] Compared with the prior art, the utility model has the following beneficial technical effects:

[0012] The utility model uses a driving mechanism of the mixing machine body to drive the mixing roller group to rotate in the opposite direction to mix the silica gel. When the mixing roller group rotates, the transmission mechanism drives the bidirectional ball screw to rotate, so that the ball nut moves horizontally, so that the cleaning ring moves along the mixing roller group, and then the attachments on the surface of the mixing roller group are cleaned, so that the cleaning of the surface of the mixing roller group is more efficient.

[0017] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "vertical", "cross", "inside", "outside", "front", "back" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] like Figures 1 to 3 As shown, a silica gel mixer proposed in an embodiment of the utility model comprises a mixer body 100, on which a mixing roller group 110 and a bidirectional ball screw 104 are arranged, the mixing roller group 110 and the bidirectional ball screw 104 are arranged in parallel, and the connecting shaft of the mixing roller group 110 is transmission-connected to the bidirectional ball screw 104 through a transmission mechanism;

[0020] The bidirectional ball screw 104 is provided with a ball nut 105 , and a cleaning ring 107 is detachably mounted on the ball nut 105 . When the ball nut 105 moves along the bidirectional ball screw 104 , the cleaning ring 107 can move along the mixing roller group 110 .

[0021] When cleaning is required, the driving mechanism of the mixer body 100 drives the mixing roller group 110 to rotate in the opposite direction to mix the silicone. When the mixing roller group 110 rotates, the transmission mechanism drives the bidirectional ball screw 104 to rotate, so that the ball nut 105 moves horizontally, so that the cleaning ring 107 moves along the mixing roller group 110, and then the attachments on the surface of the mixing roller group 110 are cleaned, making the cleaning of the surface of the mixing roller group 110 more efficient.

[0022] In this embodiment, the transmission mechanism includes a first synchronous wheel 101 connected to the mixing roller set 110 and a second synchronous wheel 103 fixed to the bidirectional ball screw 104 . The first synchronous wheel 101 and the second synchronous wheel 103 are connected through a synchronous belt 102 .

[0023] The first synchronous wheel 101 rotates, and under the action of the synchronous belt 102, the second synchronous wheel 103 rotates synchronously, and then the bidirectional ball screw 104 and the mixing roller group 110 rotate synchronously, so that the ball nut 105 can move.

[0024] In an optional embodiment, the cleaning ring 107 has two through holes, the mixing roller set 110 is respectively located in the two through holes of the cleaning ring 107 , and the through holes are coaxially arranged with the axial direction of the mixing roller set 110 .

[0025] Furthermore, when the cleaning ring 107 moves along the mixing roller set 110 , the inner surface of the cleaning ring 107 contacts the surface of the mixing roller set 110 .

[0026] The cleaning ring 107 is moved by the ball nut 105 , and the cleaning ring 107 is in contact with the surface of the mixing roller group 110 , so that the cleaning ring 107 can clean the attached matter on the surface of the mixing roller group 110 .

[0027] In this embodiment, the cleaning ring 107 is provided with a connecting rod 106, and the ball nut 105 is provided with a connecting plate 108. At least a portion of the connecting rod 106 passes through the connecting plate 108 and is locked and fixed to the connecting plate 108 by a nut. In order to ensure that the mixing roller group 110 is not affected during normal operation of the mixer, the cleaning ring 107 and the connecting plate 108 are detachably connected. When cleaning is not required, the synchronous belt 102 can be removed or the nut can be removed to separate the cleaning ring 107 from the connecting plate 108, thereby preventing the cleaning ring 107 from following the movement.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" 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, a direct connection, or an indirect connection through an intermediate medium.
