Technical Field

[0001] The utility model relates to the technical field of rubber and plastic extrusion equipment, in particular to a rubber and plastic extruder. Background Art

[0002] Rubber and plastic extruder is a basic equipment in the rubber industry and one of the key equipment that affects product quality. It plays a very important role in the production process of tires and rubber products. Rubber and plastic need to be cut after extrusion. The existing cutting method is usually done manually by staff, and manual cutting has certain defects. Due to product processing requirements, some rubber and plastic cuts need to be smooth. However, manual cutting is prone to certain errors, so the cuts are not smooth enough. It is necessary to cut the rubber and plastic many times. On the one hand, it will take a certain amount of time, and on the other hand, it will waste a certain amount of rubber and plastic raw materials, which is troublesome. For this reason, we propose a rubber and plastic extruder. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] See also Figure 1-5 The utility model provides a technical solution: a rubber and plastic extruder, including an extruder body 1, which is the prior art, and also includes:

[0029] Frame 2, frame 2 is located at the rubber and plastic extrusion part of the extruder body 1, that is, the place where the extruder body 1 extrude rubber and plastic;

[0030] The arc-shaped plate 3 is rotatably arranged on the frame 2, and a plurality of arc-shaped plates 3 are arranged, and two arc-shaped plates 3 form a group, and the extruded rubber and plastic are placed on a group of arc-shaped plates 3;

[0031] A cutting knife 4, wherein the cutting knife 4 is slidably arranged on the frame 2;

[0032] The positioning component 5 is arranged on the frame 2, and the sliding cutting knife 4 is used to fix the rubber and plastic on the arc plate 3 through the positioning component 5 to cut the rubber and plastic. Specifically, the positioning component 5 includes a shaft 51 fixedly connected to the cutting knife 4, and the shaft 51 is located on the frame 2 and slides. A semicircular ring 52 is slidably arranged on the frame 2, and a spring 53 is arranged between the semicircular ring 52 and the shaft 51, and the two ends of the spring 53 are respectively fixedly connected to the shaft 51 and the semicircular ring 52;

[0033] When it is desired to cut the rubber and plastic and the incision is to be smooth, the shaft 51 is slid downward to drive the cutting knife 4 to slide longitudinally, thereby driving the spring 53 to slide downward, thereby driving the semicircular ring 52 to slide downward. Before the cutting knife 4 falls on the rubber and plastic, the semicircular ring 52 firstly presses the rubber and plastic on the arc plate 3 tightly through the elastic force of the spring 53, and then the cutting knife 4 cuts the rubber and plastic to make the incision as smooth as possible. The function of the spring 53 is that when the extruder body 1 is extruding, if the semicircular ring 52 is pressed on the arc plate 3, it may affect the extrusion of the rubber and plastic, and the spring 53 can be pulled by the shaft 51 so that it will not block the rubber and plastic, and it can be pressed down when it is desired to cut, which is convenient, fast, simple and practical.

[0034] The arc plate 3 is provided with a rotating assembly 6, and the arc plate 3 is driven to rotate by the rotating assembly 6. Specifically, the rotating assembly 6 includes a second shaft 61 fixedly connected to the frame 2, and the second shaft 61 is rotatably connected to the two arc plates 3 at the same time. A plate 1 62 is installed on the second shaft 61, and a bolt 63 is rotatably connected to the plate 1 62 through a thread, and the bolt 63 is divided into two sections, and the thread directions of the two sections of the bolt 63 are opposite. A baffle 64 is rotatably provided on the bolt 63 through a thread, and the baffle 64 contacts and abuts against the arc plate 3, and the baffle 64 is located on the frame 2 and slides;

[0035] When the distance between the two arc plates 3 is to be adjusted, the bolt 63 is rotated to drive the threads on both sides to rotate simultaneously, thereby making the baffles 64 on both sides move towards each other at the same time, that is, with the second axis 61 as the center, the arc plates 3 on both sides are deflected simultaneously and synchronously, so that the arc plates 3 always maintain mirror symmetry, which has the advantage of facilitating the adjustment of the angle of the arc plates 3 so that they can better clamp the rubber and plastic. Because some rubber and plastic have different sizes and diameters, the rubber and plastic can be better positioned through the adjustable arc plates 3.

[0036] Two groups of semicircular rings 52 are provided, and a cutting knife 4 slides between the two groups of semicircular rings 52. The two groups of semicircular rings 52 correspond to the two groups of arc plates 3. Similarly, a cutting knife 4 slides between the two groups of arc plates 3 to cut the rubber and plastic in the middle. The rubber and plastic are positioned at the same time by the two groups of arc plates 3 and the two groups of semicircular rings 52, and then cut between the two groups of arc plates 3 and the semicircular rings 52, which can ensure that the incision of the rubber and plastic is as complete as possible.

[0037] A shaft three 7 is slidably provided on the semicircular ring 52, and the shaft three 7 and the shaft one 51 are fixedly connected to the two ends of the spring one 53 respectively, so as to drive the spring one 53 to move through the shaft three 7. The shaft three 7 makes the movable range of the spring one 53 larger, and the advantage is that there is no need to worry about the cutting knife 4 being unable to cut completely due to insufficient space when the spring one 53 is squeezed, and the shaft three 7 can also rotate on the semicircular ring 52, which has the advantage of making it convenient for the spring one 53 to adjust its own position and will not block the falling of the semicircular ring 52.

[0038] There are two groups of bolts 63, which correspond to the two groups of arc plates 3 respectively. The advantage of two groups is that they are more stable and the two groups of arc plates 3 can be adjusted separately to make them more suitable for the extruded rubber and plastic.

[0039] Example 2

[0040] See also Figure 1-7 The utility model provides a technical solution: a rubber and plastic extruder, and embodiment 2 is optimized based on embodiment 1.

[0041] A stopper 8 is slidably provided on the frame 2. The front end of the stopper 8 is triangular in design and contacts with the shaft 1 51. A spring 2 9 is provided on the stopper 8. The two ends of the spring 2 9 are respectively in contact with the stopper 8 and the frame 2 to position the cutting knife 4. When the cutting knife 4 is not in use, the shaft 1 51 is slid upward, and then the shaft 1 51 contacts and contacts with the stopper 8, and pushes the stopper 8 to slide through the inclined surface of the triangle. At this time, the spring 2 9 is squeezed. When the shaft 1 51 continues to slide upward, the stopper 8 pops out under the action of the spring 2 9, presses against the shaft 1 51, and makes the shaft 1 51 unable to move, thereby completing the positioning of the shaft 1 51, and then locking the cutting knife 4. If you want to unlock the cutting knife 4, slide the stopper 8 in the opposite direction to disengage the shaft 1 51 from the stopper 8.
