Abstract
The utility model relates to a wire drawing machine, in particular to a pre-stretching wire drawing machine capable of pre-stretching a plastic film wire. The pre-stretching wire drawing machine is provided with a frame, a motor speed reducer and a pre-stretched steel roller set, wherein a transmission steel roller set in constant-linear-speed transmission connection is arranged on one side of the frame, and is in transmission connection with the motor speed reducer; the pre-stretched steel roller set is in constant-linear-speed transmission connection; the linear speed of the pre-stretched steel roller set is higher than that of the transmission steel roller set; a tail end steel roller of the transmission steel roller set is a hot roller inside which a heating device is arranged; and a tail end steel roller of the pre-stretched steel roller set is in rolling connection with a first wire pressing rubber roller. Due to the adoption of the pre-stretching wire drawing machine, the technical problem of non-ideal stretching effect of the conventional wire drawing machine is solved, pre-stretching is performed before stretching of the plastic film wire, and a stretched plastic film has higher plasticity and intensity.
Description
Technical field
The utility model relates to a kind of wire drawing machine, particularly a kind of predraft wire drawing machine that can stretch in advance to the film silk.
Background technology
Wire drawing machine is a widely used machinery in Polywoven Bag is produced, and it is widely used in the manufacturing of Polywoven Bag, flexible container bag.The Polywoven Bag wire drawing machine comprises several sections compositions such as extruder, film head, water tank, traction wire dissecting machine, wire drawing machine, retraction machine, winder.
Traditional slow-speed of revolution (50m/min-280m/min) wire drawing machine when stretching because in baking oven the time of staying longer, so only need adopt one group of cambered plate or baking oven just can reach desirable drawing effect.And have only one baking oven on present high rotating speed (more than the 280m/min) wire drawing machine, because the time that the film silk stops is too short,, can not carry out sufficient preparation during stretching in baking oven for road, back retraction operation so can not reach desirable draw ratio.
The utility model content
The technical problems to be solved in the utility model is: it is not good to solve existing wire drawing machine drawing effect when high speed, and the film silk intensity and the unfavorable technical problem of toughness of coming out stretch.The utility model provides a kind of predraft wire drawing machine, and it just carries out predraft to the film silk before the film silk enters into wire-drawing process, makes the intensity and the tough performance of the plastic film silk after the stretching reach desirable effect.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of predraft wire drawing machine, have frame and motor reducer, one side of frame is equipped with the transmission steel rider group that Constant Linear Velocity is in transmission connection, transmission steel rider group and motor reducer are in transmission connection, it is characterized in that: also comprise the predraft steel rider group that Constant Linear Velocity is in transmission connection, the linear velocity of predraft steel rider group is greater than the linear velocity of transmission steel rider group, the terminal steel rider of described transmission steel rider group is the hot-rolling that inside is provided with heater, and the terminal steel rider of predraft steel rider group rolls and is connected with the first silk pressing rubber roll.
In order to make the plastic film silk tensile evenly, described hot-rolling rolls and is connected with the second silk pressing rubber roll.
In order to make the predraft better effects if, described frame opposite side is equipped with and makes the more steady reliable expansion tightening wheel of chain transmission.
The beneficial effects of the utility model are: this predraft wire drawing machine, before stretching, carry out predraft, and for wire drawing work afterwards has been beforehand with preparation, shortened the time of wire drawing like this, make the plasticity and the intensity of the plastic film after the stretching better.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the specific embodiment of predraft wire drawing machine of the present utility model.
Among the figure: 1, frame, 2, motor reducer, 3, transmission steel rider group, 4, predraft steel rider group, 5, hot-rolling, 6, the first silk pressing rubber roll, 7, the second silk pressing rubber roll, 8, expansion tightening wheel.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The specific embodiment of predraft wire drawing machine of the present utility model as shown in Figure 1, it has frame 1 and motor reducer 2, one side of frame 1 is equipped with the transmission steel rider group 3 that Constant Linear Velocity is in transmission connection, transmission steel rider group 3 is in transmission connection by chain by the steel rider that has sprocket wheel and forms, transmission steel rider group 3 is in transmission connection with motor reducer 2 chains, wherein also comprise the predraft steel rider group 4 that Constant Linear Velocity is in transmission connection, the linear velocity of predraft steel rider group 4 is greater than the linear velocity of transmission steel rider group 3, the terminal steel rider of transmission steel rider group 3 is hot-rollings 5 that inside is provided with heater, and the terminal steel rider of predraft steel rider group 4 rolls and is connected with the first silk pressing rubber roll 6.Hot-rolling 5 rolls and is connected with the second silk pressing rubber roll 7, the second silk pressing rubber roll 7 can be pushed down the plastic film silk during predraft like this, guarantee that the plastic film silk can not be stretched in transmission course, just stretch when having only the predraft of arrival zone that the plastic film silk is tensile more even like this.Frame 1 opposite side is equipped with and makes the more steady reliable expansion tightening wheel 8 of chain transmission, in the time of can avoiding the sag increase of chain like this, and the bad or disengaging engagement of chain and lower sprocket engagement.
Have only baking oven one on the present high rotating speed wire drawing machine, because the time that the film silk stops is too short,, can not carry out sufficient preparation during stretching in baking oven for road, back retraction operation so can not reach desirable draw ratio.Before the plastic film silk enters into baking oven and carries out wire drawing, earlier the plastic film silk is carried out predraft now, can make the plasticity of plastic film silk and intensity better like this, drawing effect can be desirable more.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
