Description

[0001] The invention relates to the technical field of belt making machine equipment, in particular to a three-roller wire separation device controlled by constant tension. Background Art

[0002] The belt making machine is a production equipment used to produce belt materials. When the belt-belt material is made of silk thread and plastic, it is also called plastic-coated belt. When the inside is steel wire and the outer layer is coated with polyethylene plastic, it can also be called plastic-coated steel belt, which makes the belt have strength, corrosion resistance and waterproof properties.

[0003] At present, in the process of producing belts by belt making machines, the two ends of the silk-steel wire are usually connected to the wire-releasing mechanism and the traction mechanism, so that the silk-steel wire can run on the production line, and when the silk-steel wire passes through the compression molding machine side by side, plastic is wrapped on the silk-steel wire.

[0004] However, due to the long distance between the wire-steel wire and the wire-paying mechanism and the traction mechanism, the tension of the wire-steel wire is unstable, causing it to bend. Even if several wires-steel wires are placed side by side into the compression molding machine through the traction mechanism and the wire-paying mechanism, bending will still occur, resulting in several wires-steel wires being uneven and having unequal spacing between each other, which in turn makes the arrangement of the wires-steel wires inside the processed belt substandard, thereby reducing the performance of the belt.

[0005] To this end, a three-roller wire separation device with constant tension control is proposed, which is used for convenient and efficient adjustment and constant silk-steel wire tension and convenient and efficient wire separation. Summary of the invention

[0034] Refer to Figure 1 As shown in the figure, a wire splitting comb 7 is provided at the front end of the left mounting plate 5 and the right mounting plate 51 through a height adjustment component. The height adjustment component is used to adjust the height of the wire splitting comb 7.

[0035] The heights of the rear pressure roller 4 and the front pressure roller 8 are equal, and the height of the middle pressure roller 3 is lower than that of the rear pressure roller 4 or the front pressure roller 8.

[0036] Through the settings and cooperation of the hysteresis brake 2, the middle pressure roller 3, the front pressure roller 8, etc. in this device, since the height of the middle pressure roller 3 is lower than that of the rear pressure roller 4 and the front pressure roller 8, the contact area between the steel wire 10 and the middle pressure roller 3 is increased, thereby improving the adjustment effect of the braking torque generated by the hysteresis brake 2 on the tension of the steel wire 10. And with the adjustable height of the wire splitting comb 7, it not only supports the steel wire 10 passing through the front pressure roller 8, making the tension of the steel wire 10 remain roughly constant, but also can fine-tune the tension of several steel wires 10 with adjusted tension by increasing or decreasing the contact surface between the steel wire 10 and the front pressure roller 8, successfully realizing the fine-tuning of the tension of the steel wire 10, making the adjustment and constant effect of the tension of the steel wire 10 by this device remarkable.

[0040] It should be noted that the rotating handle 61 is composed of a sleeve circle and a short shaft disposed at the bottom edge of the sleeve circle. Among them, the sleeve circle is sleeved on the bottom of the threaded shaft 62. During the use of this device, when it is necessary to adjust the height of the wire dividing comb 7, only the short shaft on the rotating handle 61 needs to be rotated.

[0041] Refer to Figure 1 shown. In an alternative embodiment: A bearing 32 is provided between the middle shaft 31 and the left mounting plate 5, and a bearing 32 is also provided between the middle shaft 31 and the right mounting plate 51.

[0042] It should be noted that the outer wall of the bearing 32 is fixedly connected to the left mounting plate 5 or the right mounting plate 51 by screws, while the middle shaft 31 is press-fitted with the inner wall of the bearing 32 with an interference fit.

[0043] Refer to Figure 1 shown. In an alternative embodiment: The top surface of the left mounting plate 5 is respectively provided with a first notch, a second notch, and a third notch from front to back, and the top surface of the right mounting plate 51 is also respectively provided with a first notch, a second notch, and a third notch from front to back.

[0044] It should be noted that the first notch, the second notch, and the third notch on the left mounting plate 5 and the right mounting plate 51 are the same in terms of the opening position, size, and depth dimensions. Specifically, refer to Figure 1 shown.

[0045] Refer to Figure 1 shown. In an alternative embodiment: The depth of the second notch is lower than the depths of the first notch and the third notch, and the depths of the first notch and the third notch are equal.

[0046] It should be noted that through such a setting, the heights of the rear pressure roller 4 and the front pressure roller 8 are equal, while the height of the middle pressure roller 3 is lower than that of the front pressure roller 8 or the rear pressure roller 4.

[0047] Among them, it should be supplemented that the front axle 81 is located in the first notch on the left mounting plate 5 and the right mounting plate 51, and the rear axle 41 is located in the third notch on the left mounting plate 5 and the right mounting plate 51. Both the front axle 81 and the rear axle 41 are fixedly connected in the first notch or the third notch through the T-shaped pressing block 9. The top of the T-shaped pressing block 9 is fixedly connected to the top surface of the left mounting plate 5 or the right mounting plate 51 by screws.

[0048] It should be noted that through the settings of the first notch, the second notch and the third notch, and in cooperation with the fixation of the front axle 81 and the rear axle 41 by the T-shaped pressing block 9, it is convenient for the assembly, disassembly and replacement of the front axle 81 and the rear axle 41.

[0049] Refer to Figure 1 As described above, it should be supplemented that the central axes of the middle pressing roller 3, the rear pressing roller 4, the front pressing roller 8 and the length direction of the wire dividing comb 7 are parallel to each other. The bottom of the T-shaped pressing block 9 abuts on the front axle 81 or the rear axle 41, so as to press the front axle 81 and the rear axle 41 tightly.

[0050] Refer to Figure 4 As shown, in an alternative embodiment: the wire dividing comb 7 includes a bottom comb block 71 and a top limiting block 72. A groove is formed on the top surface of the bottom comb block 71, and a plurality of comb bars 73 are arranged at equal intervals in the groove. The top limiting block 72 is fixedly connected to the top surface of the bottom comb block 71. The height of the comb bars 73 is equal to the depth of the groove. The gaps separated by the plurality of comb bars 73 are used for passing the steel wire 10.

[0051] It should be noted that, refer to Figure 4 As shown, both sides of the top surface of the bottom comb block 71 are fixedly connected with connecting blocks, and mounting grooves 75 are formed on both sides of the top limiting block 72. Fixing ports 74 are formed on the connecting blocks and at the positions of the mounting grooves 75 on the top limiting block 72. When fixing the bottom comb block 71 and the top limiting block 72, the connecting blocks extend into the mounting grooves 75. At this time, the fixing ports 74 on the connecting blocks are aligned with the fixing ports 74 on the top limiting block 72, and then bolts are passed through the fixing ports 74 and tightened with nuts screwed to the bolts, so as to fixedly connect the top limiting block 72 to the top surface of the bottom comb block 71.

[0052] Through the settings and cooperation of the bottom comb block 71, the top limiting block 72, the comb bars 73, etc., of this device, it is utilized that the steel wire 10 falls into the gaps separated by the plurality of comb bars 73 from the top groove of the bottom comb block 71, successfully realizing convenient and efficient wire dividing, ensuring that the distances between a plurality of steel wires 10 are equal, facilitating the development of its later working conditions, with delicate structural settings, convenient, efficient operation, and suitable for popularization and use in the field of tape making machines.

[0053] Refer to Figure 3As shown, in an alternative embodiment: The mounting plate 63 is in a horizontally placed convex shape. Through slots 631 are formed on both sides of the bottom end of the mounting plate 63. The bottom end of the mounting plate 63 is fixed to the corresponding left mounting plate 5 or right mounting plate 51 by screws passing through the through slots 631 and being threadedly connected thereto. The length direction of the through slots 631 is the vertical direction.

[0054] It should be noted that when adjusting the height of the mounting plate 63, the screws need to be loosened first. After the mounting plate 63 is lifted or pulled down, the screws are tightened again, so as to tightly press the mounting plate 63 against the left mounting plate 5 or right mounting plate 51. Among them, the length direction of the through slots 631 is the vertical direction, the screws are located in the through slots 631, and the diameter of the screws is equal to the width of the through slots 631, thereby limiting the adjustment of the height of the mounting plate 63 and making the operation more convenient.

[0055] Now, the working principle of this device is described through its working process:

[0056] Before using this device, it should be supplemented that this device is mainly applied to the production process of a tape making machine. Among them, a tape making machine is a production device for producing strip materials, and the specific type of the strip material is related to the raw materials. It is widely used in fields such as packaging and industrial bundling. Among them, when the tape - the strip material is made of silk and plastic, it is also called a plastic - coated silk tape. When it has steel wires inside and is coated with polyethylene plastic on the outside, it can also be called a plastic - coated steel wire tape, making the tape have both strength, anti - corrosion and waterproof properties.

[0057] This device is mainly for adjusting and constantizing the tension of the steel wires 10 and efficiently and conveniently splitting the steel wires 10 during the production process of tapes with silk, especially steel wires 10 inside.

[0058] When using this device, refer to Figure 5 As shown, the winding path of the steel wires 10 is from right to left. A plurality of steel wires 10 wind from the right side of the rear pressing roller 4 to the bottom of the middle pressing roller 3 and then wind out from the left side of the front pressing roller 8. After winding out from the front pressing roller 8, the plurality of steel wires 10 fall into the gaps separated by a plurality of comb bars 73 from the top groove of the bottom comb block 71. It should be noted that the spacing between the plurality of steel wires 10 is equal, that is, the number of comb bars 73 between adjacent two steel wires 10 is equal. Then, the top limiting block 72 is fixed to the top of the bottom comb block 71. It should be noted that the plurality of steel wires 10 are always in a state of being pulled from the left side of this device. On the production line of the tape, there are a traction mechanism and a wire releasing mechanism, which are prior arts and will not be elaborated here too much. The traction mechanism will pull the plurality of steel wires 10 to move leftward, and the wire releasing mechanism is located on the right side of this device.

[0059] After several steel wires 10 are installed on this device, start the hysteresis brake 2 to generate braking torque. Since several steel wires 10 run from right to left through the traction mechanism in the prior art, due to the action of friction, the rear pressure roller 4, the middle pressure roller 3 and the front pressure roller 8 are driven to rotate. Also, because of the braking torque generated by the hysteresis brake 2, through the transmission between its output end and the central shaft 31, the clockwise rotation of the middle pressure roller 3 is subject to a reverse resistance, thereby adjusting the tension of several steel wires 10. Also, since the height of the middle pressure roller 3 is lower than that of the rear pressure roller 4 and the front pressure roller 8, the contact area between several steel wires 10 and the middle pressure roller 3 is increased, and the duration of the friction force between the steel wire 10 and the middle pressure roller 3 is prolonged, so that the effect of the braking torque generated by the hysteresis brake 2 is better, and finally the tension adjustment of several steel wires 10 is more efficient. The several steel wires 10 with adjusted tension then pass around the front pressure roller 8. The rotation of the front pressure roller 8 facilitates the passing of the steel wire 10 and supports the steel wire 10, so that the tension of the steel wire 10 is kept substantially constant. Also, since the height of the wire dividing comb 7 is adjustable, the wire dividing comb 7 not only conveniently realizes the wire dividing of several steel wires 10 and keeps the distance between several steel wires 10 equal, but also continues to keep the tension of the steel wire 10 substantially constant by supporting the steel wire 10. At the same time, raising the height of the wire dividing comb 7 will reduce the contact area between the steel wire 10 and the front pressure roller 8, and shorten the duration of the friction force between the steel wire 10 and the front pressure roller 8, thereby reducing the influence of the front pressure roller 8 on several steel wires 10 with adjusted tension, that is, the increase in tension is reduced. On the contrary, when the height of the wire dividing comb 7 is lowered, the increase in tension is increased, further improving the fine-tuning effect of the device on the tension of the steel wire 10.

[0060] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
