Abstract

A combined belt pulling device in a flat vulcanizing machine production line includes a front steering roller, idler rollers, a frame, a clamping device, and a pressure roller device. Three idler rollers are rotatably supported on the frame in a "品" (pin) shape. A front steering roller is mounted in front of the top idler roller, and the clamping device and pressure roller device are sequentially mounted behind it. The clamping device is obliquely installed between the bottom right idler roller and the pressure roller device, with its height line perpendicular to the line connecting the bottom of the bottom right idler roller and the inlet of the pressure roller device. The top of the clamping device is lower than the top of the top idler roller. The advantages of this invention are: moving the clamping device downwards and changing its installation from vertical to oblique, eliminating the need for steering rollers before and after the clamping device, simplifying the structure, making the overall structure simpler and more compact, reducing the frame size, improving the clamping effect, and reducing manufacturing costs.

Description

Combined belt drawer device in flat vulcanizer production line

technical field

The utility model relates to a combined belt pulling machine device in a production line of a flat vulcanizer.

Background technique

The combined belt pulling machine is one of the main auxiliary machines in the production line of the flat vulcanizing machine, which mainly tensions and clamps the conveyor belt. The combined belt pulling machine has various structures, some are clamped by clamping plates, and some are clamped by rollers. For example, the belt drawing machine in the 2.6mx8m vulcanizer production line made in India (as shown in Figure 1) is clamped by a clamping plate, which mainly includes three idlers 2 arranged in a "pin" shape, and one idler 2 at the top. The front and rear steering rollers 1 and 3 are respectively arranged on the front and rear sides of the hood, and a clamping device 5 and a pressing roller device 6 are installed behind the rear steering roller 3. The above components are installed on a frame 4. The disadvantages of the above-mentioned prior art are: the clamping device 5 is installed vertically, the height of the rack 4 is high, resulting in a huge overall size of the belt pulling machine, and the height of the belt pulling machine is 3m, which seriously affects the installation and transportation; because the position of the clamping device 5 is very high. The height of the supporting device (belt cutting machine 8) at the back is much lower, and the output turning roller 7 needs to be used to guide the vulcanized belt 9 output from the turning roller 1 at the back downward, so as to facilitate the tape cutting machine at the back. 8 is aligned, which increases the manufacturing cost; in addition, during the vulcanization process of the conveyor belt in the existing device, occasionally the conveyor belt slips, and the clamping effect is average.

SUMMARY OF THE INVENTION

The utility model provides a novel combined belt drawing machine device in the production line of a flat vulcanizer, so as to solve the problems of large volume, complex structure and high manufacturing cost in the prior art.

The technical scheme of the utility model is: a combined belt drawing machine device in the production line of a flat vulcanizer, comprising a front turning roller, a supporting roller, a frame, a clamping device and a pressing roller device, and the three supporting rollers are in the shape of "pin". It is rotatably supported on the frame, and the three idlers are connected to the power unit through a transmission mechanism; a front steering roller is installed in front of one idler at the top, and a clamping device and a pressing roller device are installed in sequence behind the idler. , characterized in that the clamping device is installed obliquely between the back of the idler in the lower right and the pressure roller device, and the height line of the clamping device is perpendicular to the bottom of the idler in the lower right and the pressure roller. The connecting line between the inlets of the roller device; the top of the gripping device is lower than the top of the top of one of the idlers.

The advantages of the utility model are: the position of the clamping device is moved downward, and the vertical installation is changed to the inclined installation, the steering rollers before and after the clamping device are omitted, the structure is simplified, the overall structure is simpler and more compact, and the Rack size, lower manufacturing cost. The pressure of the hydraulic cylinder in the clamping device is increased by 2Mpa to increase the clamping force and optimize the clamping effect.

Detailed ways

Referring to Figure 2, a combined belt pulling machine device in a flat vulcanizer production line of the present utility model includes a front turning roller 1, an idler 2, a frame 4, a clamping device 5 and a pressing roller device 6, and three idlers 2 It is rotatably supported on the frame 4 in the shape of a "pin", and the three idlers 2 are connected to the hydraulic motor through a transmission mechanism (not shown); The back of the idler 2 is equipped with a clamping device 5 and a pressing roller device 6 in turn. It is characterized in that the clamping device 5 is installed obliquely between the back of the idler 2 and the pressing roller device 6 in the lower right corner, The height line of the clamping device 5 is perpendicular to the connection line between the bottom of the idler 2 and the inlet of the pressing roller device 6 at the lower right (tangent to the bottom of the idler 2); the top of the clamping device 5 is low at the top of one of the idlers 2 at the top. All the components of the utility model are in the prior art, but the installation method is improved.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described:

1. The height H1 of the combined belt drawing machine device frame 4 in the existing production line made in India shown in FIG. 1 is 2904 mm, and the elevation H2 of the belt cutting machine 8 is 750 mm. The clamping device 5 (Fig. 2) of the present invention is changed from vertical installation to inclined installation, and the height H1 of the rack 4 is changed from the original 2904mm to 1828mm, which is more than 1m lower than H1 in Fig. 1, and the figure is omitted. 1. The rear turning roll 3 with a diameter of φ450mm also omits the output turning roll 7 before entering the belt cutting machine 8 for the entire vulcanizer production line.

2. The angle a between the clamping device 5 of the present invention and the frame base is 66°.

3. The power device of the present utility model: due to the large pulling force of the belt, up to 180KN, the diameter of the idler 2 is φ900mm, and one idler in the lower front part is driven by the current transmission mechanism (synchronized belt transmission or chain transmission mechanism). Some motor reducer drives are changed to hydraulic motor drives, which saves about 15,000 yuan.
