Description

Technical Field

[0001] The utility model relates to a rubber pad extruder. Background Art

[0002] Rubber extruder is a kind of equipment specially used for producing rubber products, usually composed of extruder, cooling system, cutting system, traction system and winding system, etc. It can produce rubber products of various shapes and sizes, such as rubber hoses, rubber strips, rubber sheets, etc., by heating and extruding rubber raw materials.

[0003] The main working principle of the rubber extruder is: put the rubber raw material into the hopper of the extruder, and after heating and plasticization, the rubber raw material is squeezed into a strip or plate with the same shape as the end of the extruder through the screw of the extruder. Then, it is cooled by the cooling system, and then cut by the cutting system to form the required rubber products. Finally, the rubber products are rolled and packaged by the traction system and winding system for subsequent use.

[0004] The existing small rubber extruder has a low temperature during use, and the extruded rubber sheet is small in size, so it can be cooled by water cooling or air cooling. The existing air cooling generally sets a fan at the extrusion position to enhance heat dissipation in the form of air convection. After the heat dissipation is completed, the pad needs to be cut so that the specifications of the pad are relatively consistent. The above setting requires at least one cutting machine and an air cooler to operate independently, and cooperate with CNC technology to realize the timing cutting function of the cutting machine, and the design cost is high.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, a rubber pad extruder includes a bracket 1. An extrusion device 2 for extruding the rubber pad is provided on one side of the bracket 1. The extrusion device 2 includes a screw (not shown in the figure) and a conveying frame 4 arranged outside the screw. The conveying frame 4 is fixed on the bracket 1, and a hopper 5 for feeding is provided on one side of the conveying frame 4. The screw is connected to the extrusion motor 6, and the extrusion motor 6 drives the screw to rotate, so that the rubber particles entering the hopper 5 are conveyed and extruded by the screw. Generally, a heating system is also provided on the conveying frame 4 for melting plastic particles. The above is the structure of a general rubber extruder, which is a prior art, so it is not repeated.

[0025] The core technical solution of this application is as follows:

[0026] like Figure 2 , Figure 3 , Figure 4As shown, in order to solve the problem of timed cutting during air cooling, the present application is provided with a box body 7 on one side of the bracket 1. The box body 7 is hollow and the bearings on both side walls are connected with a rotating shaft 8 and a driving shaft 9. The rotating shaft 8 and the driving shaft 9 are provided with a plurality of fan blades 10 on the inner side of the box body 7.

[0027] Among them, two rotating shafts 8 and two driving shafts 9 are respectively provided and arranged on the side walls of the box body 7. A transmission wheel 11 is connected to the side where the rotating shaft 8 and the driving shaft 9 pass through the box body 7. A transmission belt 12 is arranged between the transmission wheels 11. The rotating shaft 8 and the driving shaft 9 rotate simultaneously through the action of the transmission belt 12. In addition, a driving motor 13 is also connected to one end of the rotating shaft 8 to drive the rotating shaft 8 to rotate, thereby driving the fan blades 10 to rotate, and cooperates with the transmission belt 12 to drive the driving shaft 9 to rotate, so that the fan blades 10 on the same side rotate at the same time, and the wind direction is toward the inside of the box body 7, so that the rubber pad passing through the box body 7 is cooled by the wind from the fan blades 10 to accelerate the cooling speed.

[0028] Correspondingly, one end of the driving shaft 9 is connected to a driving wheel 14. The driving wheel 14 is meshed with a gear 15. The diameter and number of teeth of the gear 15 are greater than the diameter and number of teeth of the driving wheel 14. When the driving wheel 14 rotates for multiple turns, the gear 15 rotates for one turn.

[0029] As mentioned above, one end of the gear 15 is connected to the bracket 1 through a rotating rod bearing. A driving rod 16 is hinged at an eccentric position of the gear 15. A driving rod 2 17 is hinged to the driving rod 16. A connecting rod 18 is hinged to the driving rod 2 17. A cutter 19 is connected to one end of the connecting rod 18. Among them, a slide groove 20 matching the cutter 19 is provided on the surface of the box body 7. The cutter 19 can be provided with a slider (not shown in the figure) in conjunction with the slide groove 20, so that the cutter 19 slides on the surface of the box body 7. In detail, the slider and the slide groove 20 can be set in the manner of a dovetail groove and a dovetail block, which restricts the cutter 19 from sliding up and down on the box body 7.

[0030] Overall working process:

[0031] 1. Pour the plastic particles into the hopper 5 and enter the conveying frame 4, start the heating device and the extrusion motor 6, so that the motor drives the screw to rotate and melt the plastic particles through the heating system. When the screw rotates, the plastic particles are conveyed and gradually extruded;

[0032] 2. A mold with a corresponding pad shape is set at the end of the conveying frame 4, so that the extruded plastic is a rubber pad;

[0033] 3. After the rubber pad is extruded, it enters the box body 7, and the drive motor 13 is started. The drive motor 13 drives the rotating shaft 8 to rotate, and cooperates with the transmission wheel 11 and the transmission belt 12 to drive the driving shaft 9 to rotate. The driving shaft 9 and the rotating shaft 8 simultaneously drive the fan blades 10 connected to themselves to rotate rapidly, so as to quickly cool the rubber pad entering the box body 7;

[0034] 4. The driving wheel 14 rotates under the action of the driving shaft 9, driving the gear 15 to rotate, thereby causing the driving rod 16 and the driving rod 2 17 to swing back and forth, so that the cutter 19 slides up and down quickly on one side of the box body 7, cutting the extruded rubber pad into the same specifications and fully cooling it through the action of air cooling;

[0035] 5. Repeat the above steps so that the extruded rubber pads are arranged and removed in sequence.

[0036] It should be noted that:

[0037] The above-mentioned rubber pad extruder is a small extruder;

[0038] The size and number of teeth of the gear 15 can be adjusted according to actual needs;

[0039] The rotation speed of the driving motor 13 is greater than that of the extrusion motor 6, so that the cutter 19 can move up and down quickly. The rotation speed of the driving motor 13 can be adjusted according to the required length specifications of the pad to obtain rubber pads of different specifications.

[0040] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
