FIG. 5 is a front view of FIG. 2;
FIG. 6 is a cross-sectional view taken along line A-A of FIG. 5;
FIG. 7 is a right side view of FIG. 4
As shown in fig. 5, 6 and 7, the power transmission unit 30 is used to provide power for the glue can extruding unit 20 to extrude glue.
The power transmission section 30 has two motors 31, two drive sprockets 32, four driven sprockets 33, and one transmission chain 34. Wherein, two driving sprockets 31 are arranged in parallel at intervals on the middle part of the inner side 11a of the base plate 11; the four driven chain wheels 32 are symmetrically arranged near four corners on the inner side 11a of the base plate 11 in pairs, and a transmission chain 34 sequentially surrounds the four driven chain wheels 33 and the outer sides of the two driving chain wheels 32 and is respectively meshed and connected with the driven chain wheels and the driving chain wheels; two motors 31 are provided on the outer side 11b of the base plate 11 and respectively drive two driving sprockets 31, and each lead screw 21 is mounted on a corresponding driven sprocket 33 to be driven by the driven sprocket 33: thus, the two motors 31 respectively drive the two driving sprockets 32 to rotate, and then drive the transmission chain 34 to rotate and drive the four driven sprockets 33 to rotate, so that the four movable screws 21 can be respectively driven to move forwards, and the corresponding pistons 22 can be respectively pushed, so that the cable insulation coating raw material can be extruded from the corresponding glue tanks 400. This structure is owing to can let driving chain 34 realize pulling the chain on one side at driving sprocket 32 both sides, supply with the chain simultaneously, can guarantee like this that motor 31 transmission is balanced, so guarantee driving chain 34 atress balanced to, in operation, two motors 31 syntropy rotate, drive driving chain 34 to a direction motion jointly, lead to 4 driven pulleys 31 synchronous revolution, thereby realize pushing four glue tanks 400 of biggest and ejection of compact simultaneously, be used for the cable coating simultaneously.
In addition, the driven sprocket 33 is mounted with the corresponding screw shaft 21 through a T-shaped screw hole provided at the center to drive the screw shaft 21. T type screw thread is light little compared ball, and is cheap, durable, need not maintain, and then load is big for the triangle screw thread, and the helical pitch is big, and the motion effect is good.
In addition, the power transmission part 30 further has two driving wheel carriers 35 and four driven wheel carriers 36 in order to facilitate the fixed mounting of the driving sprocket 32 and the driven sprocket 33. The two driving wheel frames 35 are respectively fixed on the inner side 11a of the base plate 11 for respectively supporting and mounting the two driving sprockets 32, and the four driven wheel frames 36 are respectively fixed on the inner side 11a of the base plate 11 for respectively supporting and mounting the four driven sprockets 33.
And, each of the driving wheel carriers 35 is mounted on the base plate 11 through a first in-line hole 35a, and at the same time, each of the motors 31 is mounted on the corresponding driving sprocket 32 through a second in-line hole (not shown) formed in the base plate 11. Thus, the drive chain 34 can be tightened by adjusting the position of the driving wheel carrier 35 in the first linear hole 35a and correspondingly adjusting the position of the motor 31 in the second linear hole.
In addition, the power transmission portion 30 has two screw rotation preventing links 37. Both ends of the screw rotation preventing connecting rod 37 have a straight hole, respectively, and a hexagonal nut is screwed on one end of the screw 21 located on the outer side 11b of the base plate 11. Therefore, when cable insulation coating raw materials need to be extruded, one screw rod anti-rotation connecting rod 37 can be respectively sleeved on the respective hexagon nuts of the two screw rods 21 through the straight holes at the two ends, so that the screw rods 21 can be ensured not to rotate in the working process and only move back and forth along the direction of the screw rods 21, and therefore the force for pushing the screw rods 21 forwards is large, and the cable insulation coating raw materials in the glue tank 400 can be pushed out conveniently; when the glue tank 400 is installed, the two screw anti-rotation connecting rods 37 can be removed in a spiral disassembling mode, and then the screw rod 21 can be rapidly withdrawn by directly rotating the screw rod 21 at a high speed by using a high-speed electric screwdriver, so that the glue tank 400 can be rapidly replaced or installed.
In addition, the inner side 11a of the base plate 11 is further provided with four lower limit piston switches 22a corresponding to the bottoms of the four pistons 22, respectively, one ends of the four lead screws 21 located on the outer side 11b of the base plate 11 are further provided with four upper limit collision rings 22c, respectively, and the outer side 11b of the base plate 11 is further provided with four upper limit piston switches 22b corresponding to the four upper limit collision rings 22c, respectively. Thus, when the screw 21 moves forward, the piston 22 is pushed for pushing the glue pot 400, and when the screw 21 moves backward, the piston 22 will collide at the bottom with the lower limit piston switch 22a mounted on the base plate 11 for informing the control system to stop the driving of the motor 31; meanwhile, when the screw 21 moves forward, if the piston 22 pushes the glue pot 400 to the end, the upper limit collision ring 22c collides with the upper limit piston switch 22b, which also informs the controller to stop the driving of the motor 31. Through the control, the movement of the screw 21 is automatically controlled.
In addition, the ring body 12b1 has a slant surface 12b4 inclined toward the center of the ring body 12b1, so that when a pull rod 12a is inserted into the corresponding notch 12b2 and the glue pot 400 is pushed, the slant surface 12b4 can fold the pull rod 12a to prevent the pull rod 12a from being separated outward.
As can be seen from the above, the glue pot 400 is attached as follows: the pull rod 12a is slightly pulled outwards, the glue pot 400 is put into the glue pot from the front end, the base of the glue pot 400 is placed on the piston 22, then the restraint ring 12b is placed on the conical end cover on the glue pot 400, the four pull rods 12a are respectively put into the four openings 12b2 of the restraint ring 12b, the pull rod head 12a3 is clamped above the restraint ring 12b, the inclined surface 12b4 above the restraint ring 12b is used for drawing the pull rod 12a when the glue pot 400 is pushed, the inclined surface 12b4 can prevent the pull rod 12a from outwards disengaging, and the magnet 12b3 on the two sides of the opening 12b2 of the restraint ring 12b can prevent the pull rod 12a from outwards disengaging to a certain extent.
