Description

Technical Field

[0001] This invention relates to the field of rubber production equipment technology, and more specifically to an automatic feeding and unloading device for rubber molding equipment. Background Technology

[0002] Rubber rings are used for piston sealing in reciprocating hydraulic cylinders. They are made of polyurethane (TPU), CPU, and other rubbers, offering excellent sealing performance and a long service life. Currently, thermoforming machines are often used for processing and shaping some rubber rings. In the thermoforming process, a pre-formed part needs to be placed into a mold base for molding. Taking a simple O-ring as an example, the pre-formed part is usually placed manually in a circular mold slot, and then thermoformed by the mold base of the molding equipment to form a complete O-ring. After processing, the rubber ring will adhere to the surface of the mold base, so it needs to be manually removed by hand and tools such as shovels. However, the mold base is very hot after processing, which is dangerous. Moreover, this method of adding (placing the pre-formed part) and removing (removing the formed rubber ring) is inefficient and labor-intensive.

[0003] Therefore, this application proposes an automatic feeding and unloading device to solve the above problems. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides an automatic feeding and picking device for rubber molding equipment, which improves work efficiency, saves manpower, and reduces the intensity of manual labor.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding and part-removing device for a rubber molding equipment, comprising a machine base and a mold base, wherein the mold base includes a lower mold and a liftable upper mold, characterized in that: a guide rail is provided on the machine base, the lower mold is disposed on the guide rail and can slide along the guide rail, and an automatic feeding device and an automatic part-removing device are also provided on the machine base;

[0006] The automatic feeding device includes a base plate and a storage box. The base plate has a through hole, and the storage box is located above the through hole. A rotating roller is rotatably installed at the through hole. The rotating roller has a notch in the circumferential direction. By rotating the rotating roller, the material in the storage box is moved out through the notch and from the through hole.

[0007] The automatic item handling device includes a box body, a reciprocating scraper inside the box body, a ventilation groove inside the scraper body, the ventilation groove being connected to an external high-pressure air source via an air pipe, and air holes at both ends of the scraper body, the air holes being connected to the ventilation groove.

[0008] The present invention is further configured to include a movable base, wherein the automatic feeding device and the automatic part removal device are disposed on the movable base, and the movable base has a first working position and a second working position;

[0009] At the first work station, the automatic feeding device can cooperate with the lower mold;

[0010] In the second workstation, the automatic part-removing device can cooperate with the lower mold.

[0011] The present invention is further configured such that: the lower mold is provided with a mold groove, and at the first working position, the through hole corresponds to the position of the mold groove of the lower mold.

[0012] The present invention is further configured such that: the position of the box body corresponds to that of the lower mold, and the scraper inside the box body abuts against the surface of the lower mold.

[0013] The present invention is further configured such that the air holes on the scraper are inclined toward the surface of the lower mold.

[0014] The present invention is further configured such that: the two ends of the scraper are provided with inclined structures, and the air holes are provided at the inclined structures at both ends.

[0015] The present invention is further configured such that: a plurality of preforms are provided in the storage box, and a separator paper is provided between the plurality of preforms.

[0016] The present invention is further configured such that: the separator paper has a smooth layer and a rough layer, the preform is placed on the smooth layer, the rough layer is located on one side of the edge of the separator paper, the storage box has a receiving cavity on the side near the bottom, the receiving cavity has a rotating shaft, the rotating shaft corresponds to the position of the rough layer, and the separator paper can be moved by rotating the rotating shaft.

[0017] The present invention is further configured such that: a paper suction channel and an air pump are provided in the receiving cavity; one end of the paper suction channel is configured as a funnel-shaped structure and located at the rotating shaft; the other end is located at the air intake of the air pump; the air pump can suck the separator paper into the receiving cavity along the paper suction channel.

[0018] The invention is further configured such that the surface of the rotating shaft is provided with small spikes.

[0019] In summary, the present invention has the following beneficial effects:

[0020] Compared to existing technologies, this invention incorporates an automatic feeding device and an automatic part-removing device. Initially, the movable base is located at the second workstation. Therefore, after the rubber is hot-pressed, the lower mold moves to the automatic part-removing device via a guide rail. The automatic part-removing device then uses a scraper and its air holes to initially separate the finished product from the surface of the lower mold by blowing air. As the scraper moves, it scrapes the finished product off the lower mold and pushes it into an external collection device, completing the automatic part-removing operation. This eliminates the need for manual operation and offers higher safety and efficiency. Subsequently, the movable base cuts... The machine moves to the first station, aligning the automatic feeding device with the lower mold. Several pre-formed parts are stored in the storage bin. As the rollers rotate, notches on the rollers catch the pre-formed parts, causing them to move out through the through-hole and fall into the mold slot of the lower mold. This completes the automatic feeding process smoothly, eliminating the need for manual placement and increasing production efficiency. The lower mold can then move back along the guide rail to below the upper mold to continue the rubber hot-pressing process. After processing, the automatic part-removing device and automatic feeding device retrieve and refill the parts, continuously cycling to achieve automated production. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] This embodiment discloses an automatic feeding and unloading device for a rubber molding equipment, such as... Figure 1-5 As shown, the machine includes a base 1 and a mold base 2. The mold base 2 is equipped with an electric heating plate for heating. The mold base 2 includes a lower mold 201 and a liftable upper mold 202. The upper mold 202 is lifted up and down by an electric cylinder. When the upper mold 202 and the lower mold 201 are pressed together, hot pressing can be performed. The machine base 1 is equipped with a guide rail 101. The lower mold 201 is set on the guide rail 101 and can slide along the guide rail 101. Specifically, the movement of the lower mold 201 can be controlled by a linear motor, a lead screw slider, a cylinder, or an electric cylinder. In this embodiment, the machine base 1 is also equipped with an automatic feeding device 3 and an automatic part removal device 4. The lower mold 201 can move along the guide rail to the automatic feeding device 3 and the automatic part removal device 4.

[0029] Further details can be found by referring to... Figure 4-5 The automatic feeding device 3 of this embodiment includes a base plate 301 and a storage bin 302. The base plate 301 has a through hole 5, and the storage bin 302 is disposed above the through hole 5. A rotating roller 6 is rotatably disposed at the through hole 5, and the rotating roller 6 has a notch 7 circumferentially disposed. By rotating the rotating roller 6, the material in the storage bin 302 is moved out through the notch 7 and through the through hole 5. In the above structure, the storage bin 302 stores a plurality of preformed parts 15, and the shape of the preformed parts 15 is adapted to the through hole 5. For example, the preform can be a ring-shaped structure, and the through hole is also a ring-shaped structure. There are two rollers 6, located on both sides of the through hole 5. The notch 7 on the roller 6 can hold the preform 15. At the same time, the two rollers 6 rotate in opposite directions. For example, the right one rotates clockwise and the left one rotates counterclockwise. In this way, the two rollers 6 can move the preform 15 out of the through hole 5 together under the drive of the two rollers 6, and then it can fall into the mold groove of the lower mold 201 to complete the automatic feeding operation.

[0030] Furthermore, refer to Figure 2-3 The automatic part-retrieving device 4 includes a box body 401, inside which is a reciprocating scraper 8. The scraper 8 has a ventilation groove 801, which is connected to an external high-pressure air source via an air pipe. Air holes 802 are located at both ends of the scraper 8, communicating with the ventilation groove 801. In this structure, the box body 401 has a moving groove 14. The scraper 8 cooperates with the moving groove 14 and moves within the groove. Simultaneously, the scraper 8 can be driven by a cylinder (not shown in the figure) to reciprocate within the groove. The specific part-retrieving process involves first blowing high-pressure gas through the ventilation groove 801 and air holes 802, causing the finished products on the lower mold 201 to be initially separated by the blowing gas. Then, through the movement of the scraper 8, the pre-separated finished products are scraped off the lower mold 201, and pushed to an external collection device as the scraper 8 moves. For example... Figure 2In the process, a collection box 13 is set on one side of the box 401. The finished product is pushed into the collection box 13 for collection, and the automatic part picking operation is completed. At the same time, after the part picking is completed, during the return stroke of the scraper 8, the air hole 802 on the other side can blow away some residual impurities and dust on the lower mold 201. The scraper 8 can move back and forth several times to keep the surface of the lower mold 201 clean, which is convenient for subsequent feeding and processing.

[0031] Furthermore, this embodiment also includes a movable base 9, which can be moved by a linear motor or a gear and rack mechanism. An automatic feeding device 3 and an automatic part-retrieving device 4 are mounted on the movable base 9, which has a first station and a second station. At the first station, the automatic feeding device 3 cooperates with the lower mold 201; at the second station, the automatic part-retrieving device 4 cooperates with the lower mold 201. Through the above structure, the automatic feeding device 3 and the automatic part-retrieving device 4 are integrated and move together, resulting in a more compact structure. Switching between the first and second stations on the movable base 9 allows for switching between part-retrieving and feeding functions.

[0032] Furthermore, the lower mold 201 is provided with a mold groove 10. In the first station, the through hole 5 corresponds to the position of the mold groove 10 of the lower mold 201. With the above structure, the preform 15 can be accurately placed into the mold groove 10 when it is fed.

[0033] Furthermore, the box body 401 and the lower mold 201 are positioned correspondingly, and the scraper 8 inside the box body 401 abuts against the surface of the lower mold 201. Through the above structure, the scraper 8 abuts against the surface of the lower mold 201, which can better scrape away the finished product and clean the rubber and some dust and impurities remaining on the surface of the lower mold 201.

[0034] Furthermore, the air holes 802 on the scraper 8 are inclined toward the surface of the lower mold 201. With the above structure, the generated air force has a downward force, especially when the scraper 8 moves to the mold groove 10, the downward air can enter from the gap between the finished product and the mold groove, thereby better separating the finished product and the mold groove.

[0035] Furthermore, the scraper 8 has beveled structures at both ends, and air holes 802 are located at the beveled structures at both ends. Through the above structure, the beveled structures and air holes can lift the finished product slightly when it is pushed to move, and blow high-pressure gas in from the lifted gap. This also helps to separate the finished product from the lower mold 201 better, making it less likely to stick together.

[0036] Furthermore, the storage bin 302 contains several preformed parts. To prevent the preformed parts from sticking together, a separator paper 11 is provided between the preformed parts. Specifically, the separator paper 11 has a smooth layer 1101 and a rough layer 1102. The preformed parts are placed on the smooth layer 1101, and the rough layer 1102 is located on one side of the edge of the separator paper 11. The smooth layer 1101 can be made of common silicone paper, which has a smooth surface and will not stick to the preformed parts. The rough layer 1102 is relatively rougher than the smooth layer 1101. Generally, it can be made of simple plain paper. The storage bin 302 has a receiving cavity 12 near the bottom. The receiving cavity 12 has a rotating shaft 1201. The rotating shaft 1201 corresponds to the position of the rough layer 1102. The rotation of the rotating shaft 1201 can drive the separator paper 11 to move. Meanwhile, the receiving cavity 12 is provided with a paper suction channel 16 and an air pump 17. One end of the paper suction channel 16 is configured as a flared structure and is located at the rotating shaft 1201, and the other end is located at the air intake of the air pump 17. The air pump 17 can suck the separator paper into the receiving cavity 12 along the paper suction channel 16.

[0037] It should be noted that a grid is installed at the air intake of the vacuum pump 17 to prevent the separator paper from directly clogging the air intake. Furthermore, a detection device 18, such as an infrared detector, is installed at the flared end of the paper suction channel 16. When the separator paper is detected being moved to the flared end by the rotating shaft 1201, the vacuum pump starts briefly to quickly suck the separator paper into the receiving cavity. Then, the vacuum pump 17 stops, and the separator paper 11 naturally falls into the receiving cavity 12. Through this structure, when the preform 15 is moved by the rotating roller to the lower... After mold 201 is removed, the rotating shaft 1201 can rotate. Through the cooperation of the rotating shaft 1201 and the rough layer 1102, the separator paper 11 is moved to the paper suction channel. The separator paper is guided by the flared shape at the end of the paper suction channel to align and fit the channel. Then the detection device 18 detects the paper, the separator paper is quickly sucked away, the upper layer preform 15 falls down and cooperates with the notch, and the upper layer rough layer 1102 also falls down and cooperates with the rotating shaft 1201 to achieve continuous automatic feeding.

[0038] Furthermore, in order to ensure that the rotating shaft 1201 can smoothly drive the separator paper 11 to move, small spikes can be provided on the surface of the rotating shaft 1201, thereby increasing the gripping force of both and ensuring smooth paper collection.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present invention should be included within the protection scope of the present invention.
