Description

Technical Field

[0001] The utility model relates to an O-ring feeding structure and belongs to the technical field of feeding equipment. Background Art

[0002] O-rings with large inner diameter and thin wire diameter are put into granular or strip materials. Both the cavity and non-cavity parts need to be filled with materials. The material input is large and the cost is high. The granular material flows over a long distance and the material is easily burned, resulting in problems such as lack of material or poor trimming. If the material is pinched into a circle according to the cavity diameter and put into the cavity manually, the material usage can be reduced, but the feeding is slow and the manual feeding position is inaccurate. When the material is placed on a high-temperature mold and the material position is adjusted manually, the material becomes soft due to heat and cannot be adjusted according to the cavity position. In addition, it is easy to cause burns. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model arranges accommodating grooves, avoidance areas and limiting convex plates to cooperate with the accommodating O-rings, which is not only convenient for placement, but also ensures that the subsequent strip materials fall into the mold cavity smoothly; through the cooperation of the drawing plate, the pressing plate and the base plate, the strip materials fall into the mold cavity under the action of their own gravity, and the material is put into the mold cavity at a fast speed and with accurate positioning. At the same time, the occurrence of scalding accidents is avoided, the material usage is reduced, the material cost is saved, and the problems such as the long flow distance of the material, the scorching of the material, the easy formation of material shortage or poor trimming performance, etc. are improved.

[0004] The technical solution adopted by the utility model is an O-ring feeding structure, including a base plate, a U-shaped pressure plate, a draw plate and a positioning guide pin. The U-shaped pressure plate is located above the base plate and is connected and fixed by the positioning guide pin. The inner side of the U-shaped pressure plate is provided with a slide groove. The draw plate is plugged into and matched with the U-shaped pressure plate. A plurality of rows of accommodating grooves are provided on the upper surface of the base plate. A limiting convex plate is provided in the middle of the accommodating groove. The space between the limiting convex plate and the accommodating groove is used to accommodate granular or strip materials of the O-ring.

[0005] Furthermore, the limiting convex plate is in the shape of a major arc plate, and a clearance area is formed between the plane of the major arc plate and the inner wall of the accommodating groove.

[0006] Furthermore, the spacings between adjacent accommodating grooves are equal.

[0007] Furthermore, the positioning guide column protrudes outwardly from the upper surface of the U-shaped pressing plate.

[0008] Furthermore, a handle is provided on one side of the drawer.

[0009] The utility model discloses an O-ring feeding structure, which has the beneficial effect that compared with the prior art, an accommodating groove and a limiting convex plate cooperate to accommodate the O-ring, and the provision of an avoidance zone is not only convenient for placement, but also ensures that subsequent strip materials can smoothly fall into the mold cavity; through the cooperation of a draw plate, a pressure plate and a base plate, the strip material falls into the mold cavity under the action of its own gravity, ensuring that there is no time difference in the input of the strip material, thereby improving work efficiency, accurately positioning, reducing the scrap rate, and avoiding the occurrence of scalding accidents, thereby reducing labor intensity.

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings 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. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] In order to further understand the content of the utility model, this technical solution is further explained below in conjunction with specific implementation methods.

[0020] Embodiment 1:

[0021] like Figures 1 to 6 As shown, the present embodiment provides an O-ring feeding structure, comprising a base plate 1, a U-shaped pressure plate 2, a draw plate 3 and a positioning guide column 4, the U-shaped pressure plate 2 is located above the base plate 1 and is connected and fixed by the positioning guide column 4, the inner side of the U-shaped pressure plate 2 is provided with a slide groove 5, and a handle 8 is provided on one side of the draw plate 3, and the draw plate 3 can be inserted into the inner side of the U-shaped pressure plate 2 along the slide groove 5 or pulled out from the U-shaped pressure plate 2, a plurality of rows of accommodating grooves 6 are provided on the upper surface of the base plate 1, and the spacing between adjacent accommodating grooves 6 is equal, and a limiting convex plate 7 is provided in the middle of the accommodating groove 6, and the limiting convex plate 7 is shaped as a major arc plate, and the major arc plate is understood to be a plate larger than a semicircle, and the area between the plane of the major arc plate and the inner wall of the accommodating groove 6 is an air avoidance area 10, and the area between the major arc plate and the accommodating groove 6 is used to hold granular material or strip material 9 of the O-ring.

[0022] The positioning guide pin 4 protrudes from the upper surface of the U-shaped pressing plate 2 so that the positioning guide pin 4 can be inserted into the positioning guide sleeve when the feeding structure is turned over. The gap between the superior arc plate and the accommodating groove 6 is slightly larger than the diameter of the strip material 9, which not only allows the strip material 9 to be unfolded along the inner wall of the accommodating groove 6 without convexly bending toward the superior arc plate, but also ensures that the strip material 9 can fall into the mold cavity under the action of its own gravity.

[0023] In actual operation, Figure 5 and 6As shown, first, strip materials 9 are placed between the superior arc plate and the accommodating groove 6, wherein the air avoidance area 10 is convenient for the operator to insert his fingers into it to cross-stack the strip materials 9, and also ensure that the subsequent strip materials 9 fall smoothly into the mold cavity. After the material swinging is completed, the draw plate 3 with a handle 8 is inserted into the inner side of the U-shaped pressure plate 2, and the strip materials 9 are sealed inside by the draw plate 3. The feeding structure is turned over so that the positioning guide column 4 faces downward, and then it is transported to the mold. After the positioning guide column 4 is aligned with the positioning guide sleeve and inserted, the material swinging area corresponds to the mold cavity, and the draw plate 3 is pulled out from the U-shaped pressure plate 2. The strip materials 9 fall into the mold cavity under the action of their own gravity, ensuring that there is no time difference in the input of the strip materials 9, thereby improving work efficiency, accurate positioning, and reducing the scrap rate. At the same time, it avoids the occurrence of scalding accidents and reduces labor intensity.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
