Description
Technical Field
The utility model relates to a food, medicine packaging machinery especially relate to a controllable doffer of speed.
Background
At present, a butterfly valve or a rotary valve is usually adopted for controlling the falling speed of materials during the floor blanking in solid granulation, but the opening degree of the valve is not linear when the valve is opened, the material blanking speed cannot be stably controlled, and the two valves can only be applied to a rigid blanking pipeline and have the problem of difficulty in cleaning. In a system adopting a flexible blanking pipeline, the falling speed of a material cannot be well controlled after the whole blanking pipeline is opened, and the risk of impact generated after the material is blanked still exists.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome the not enough of prior art, provide a simple structure, can control doffer of blanking speed steadily.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a controllable doffer of speed, includes flexible blanking pipeline, still includes the frame, the frame in the both sides of flexible blanking pipeline are equipped with the swing arm, and both ends still are equipped with the guide about the frame, be equipped with the tight pivot of clamp in the swing arm, be equipped with the actuating mechanism that the tight pivot of clamp that is used for driving flexible blanking pipeline both sides is close to each other or keeps away from in the frame.
As a further improvement of the above technical solution: the driving mechanism comprises a telescopic driving piece and two connecting rods, one ends of the two connecting rods are correspondingly hinged with the two clamping rotating shafts one by one, and the other ends of the two connecting rods are hinged with the telescopic driving piece; or one end of each of the two connecting rods is hinged with the two swing arms in a one-to-one correspondence mode, and the other end of each of the two connecting rods is hinged with the telescopic driving piece.
As a further improvement of the above technical solution: the telescopic driving piece is a cylinder or an electric cylinder.
As a further improvement of the above technical solution: the flexible blanking pipeline is a polyethylene pipeline.
Compared with the prior art, the utility model has the advantages of: the utility model discloses a blanking device with controllable speed, which adopts a flexible blanking pipeline, wherein swing arms are arranged on two sides of the pipeline, and clamping rotating shafts are arranged on the swing arms and are driven by a driving mechanism to be close to or far away from each other; when the flexible blanking pipeline is clamped tightly, the falling of materials can be prevented, when the materials need to be unloaded, the two clamping rotating shafts are far away from each other, the opening of the flexible blanking pipeline is realized, the opening degree is controlled by the driving mechanism, the blanking speed is stably controlled, the structure is simple and reliable, the guide pieces are arranged at the upper end and the lower end of the rack, the control on the form of the flexible blanking pipeline is facilitated, the materials can conveniently and accurately enter the flexible blanking pipeline or can be blanked from the flexible blanking pipeline, the rolling friction is formed between the clamping rotating shafts and the flexible blanking pipeline when the clamping rotating shafts move along with the swing arms, and the damage of the flexible blanking pipeline due to the overlarge friction.

The reference numerals in the figures denote: 1. a flexible blanking conduit; 2. a frame; 3. swinging arms; 4. clamping the rotating shaft; 5. a drive mechanism; 51. a telescopic driving member; 52. a connecting rod; 6. a guide member; 7. and (3) feeding.
Detailed Description
The invention is described in further detail below with reference to the drawings and specific examples.
Fig. 1 to fig. 3 show the utility model discloses controllable doffer of speed's an embodiment, the controllable doffer of speed of this embodiment, including flexible blanking pipeline 1, still include frame 2, frame 2 is equipped with swing arm 3 in flexible blanking pipeline 1's both sides, and both ends still are equipped with guide 6 about frame 2, are equipped with on swing arm 3 and press from both sides tight pivot 4, are equipped with the actuating mechanism 5 that is used for driving the tight pivot 4 of the clamp of flexible blanking pipeline 1 both sides and is close to each other or keep away from in frame 2.
The blanking device with the controllable speed adopts a flexible blanking pipeline 1, swing arms 3 are arranged on two sides of the flexible blanking pipeline 1, clamping rotating shafts 4 are arranged on the swing arms 3, and the clamping rotating shafts 4 on the two sides are driven to mutually approach or depart through a driving mechanism 5; when the clamping rotating shafts 4 on the two sides are close to each other, when the flexible blanking pipeline 1 is clamped tightly, the material can be prevented from falling, when unloading is needed, the two clamping rotating shafts 4 are far away from each other, the opening of the flexible blanking pipeline 1 is realized, the opening degree is controlled by the driving mechanism 5, so that the blanking speed is stably controlled, the structure is simple and reliable, the guide parts 6 are arranged at the upper end and the lower end of the rack 2, the shape of the flexible blanking pipeline 1 is favorably controlled, the material can conveniently and accurately enter the flexible blanking pipeline 1 or can be blanked from the flexible blanking pipeline 1, and the clamping rotating shafts 4 move along with the swing arm 3 and are in rolling friction with the flexible blanking pipeline 1 (for example, the two ends of the clamping rotating shafts 4 can be installed on the swing arm 3 through bearings to realize rotation), and the damage of the flexible blanking. Wherein, flexible blanking pipeline 1 preferably adopts PE pipeline (polyethylene pipeline), and the cost is very low, and the material blanking in whole pipeline is accomplished the back, can directly change, need not to consider the washing problem.
