Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a C-type frame structure jointing machine. Background Art

[0002] Rubber is a commonly used material for products currently available in the market and can be molded into products of various shapes to meet the needs of production and life.

[0003] Currently, for rubber products with a strip structure, the length of a single strip is limited due to equipment space and manufacturing process constraints. To produce longer products, two or more strips of rubber products must be spliced together to meet production requirements. For example, in the processing of rubber conveyor belts, patent CN115246241A discloses a rubber conveyor belt production method that softens the rubber material, cuts it into small pieces, and plasticizes it. Compounding agents are then added according to the required strength to obtain a rubber compound. The rubber compound is then calendered to obtain a rubber splicing segment. A separating and cutting device is then used to process the rubber splicing segments into card strips and card slots. Multiple rubber splicing segments are spliced together to form a rubber conveyor belt with adjustable length. Although the above structure can meet the length extension requirement, the two adjacent rubber splicing sections are connected to each other through the card groove and the card strip. Although it can meet the connection requirement, in actual use, in order to prevent the two adjacent rubber splicing sections of the formed rubber conveyor belt from accidentally detaching, it is also necessary to provide a semicircular groove perpendicular to the card groove and the card strip on each rubber splicing section, and install a reinforcing connecting rope in the semicircular groove. The reinforcing connecting rope forms a restraining structure on the inner and outer sides of the spliced rubber conveyor belt. Not only does it have the problems of cumbersome process steps and inconvenient production and manufacturing, which affects processing efficiency, but it also causes the surface of the formed rubber conveyor belt to be uneven. For the transportation of some small products, small products are very easy to fall and get stuck in the gap between the semicircular groove and the reinforcing connecting rope, which has great restrictions on use. Summary of the Invention

[0004] In view of the above-mentioned problems existing in the prior art, the present invention aims to provide a C-type frame structure jointing machine, which is equipped with upper and lower pressure plates, and a core material placement hole is opened on one pressure plate, and a hot pressing part corresponding to the core material placement hole is also provided. The ends of the two splicing sections are placed between the upper and lower pressure plates from both sides and pressed tightly, and a gap is left between the two splicing sections and corresponding to the core material placement hole in the vertical direction. After the core material is placed through the core material placement hole, it is pressed tightly by the hot pressing part to achieve high temperature and high pressure vulcanization, thereby realizing the end connection of the two splicing sections. There is no need for grooving processing and setting an external restraint structure, which ensures the original state of the product.

[0027] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To the attached Figure 4The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0028] Figure 1 This is a structural diagram of an embodiment of a C-frame structure jointing machine of the present utility model. Figure 1 As shown, the C-frame structure jointing machine provided in this embodiment includes: a frame 1, a pressing plate 2, a hot pressing piece 3 and a telescopic mechanism 4.

[0029] Specifically, the frame 1 is arranged in a C-shape, with protruding structures on both sides of the frame 1 serving as mounting structures for subsequent components. This also allows for an integrated arrangement of components on the frame 1 for mounting other components, resulting in improved integrity, higher structural strength, and better adaptability to high-voltage environments. The upper end of the frame 1 serves as a mounting end 11 for mounting other components, while the lower end of the frame 1 serves as a workstation 12 for convenient placement of the segments to be spliced.

[0030] Specifically, the pressing plate 2 includes an upper pressing plate 21 and a lower pressing plate 22. During installation, the lower pressing plate 22 is installed on the workbench 12 and used as a fixed bearing structure. The upper pressing plate 21 is installed on the installation end 11, and the upper pressing plate 21 and the lower pressing plate 22 are facing each other in the vertical direction, which provides conditions for the upper pressing plate 21 to cooperate with the lower pressing plate 22 to press the two spliced sections. In addition, the upper pressing plate 21 is provided with a core material placement hole 2111 that passes through in the vertical direction. When the ends of the two spliced sections are placed between the upper pressing plate 21 and the lower pressing plate 22, a gap is set between the ends of the two spliced sections, and the gap is facing the core material placement hole 2111 in the vertical direction, which provides conditions for the core material for connection to be placed from the core material placement hole 2111 into the gap between the ends of the two spliced ends.

[0031] Specifically, the hot pressing part 3 is installed on the mounting end 11 and is located above the upper pressing plate 21, and the hot pressing part 3 is vertically opposite to the core material placement hole 2111, so that the subsequent hot pressing part 3 can be pressed into the core material placement hole 2111 and provide conditions for high temperature and high pressure vulcanization of the core material.

[0032] Figure 2 This is a schematic diagram of the installation of a telescopic mechanism of a preferred embodiment of the present utility model. Figure 1 and Figure 2As shown, the telescopic mechanism 4 includes a first telescopic mechanism 41 and a second telescopic mechanism 42. During installation, the first telescopic mechanism 41 and the second telescopic mechanism 42 are arranged in the vertical direction, and the first telescopic mechanism 41 is set between the installation end 11 and the upper pressure plate 21. The first telescopic mechanism 41 drives the upper pressure plate 21 to move up and down in the vertical direction, thereby cooperating with the lower pressure plate 22 to press and heat the two splicing ends to be spliced. Similarly, the second telescopic mechanism 42 is set between the installation end 11 and the hot pressing part 3, so that the second telescopic mechanism 42 can drive the hot pressing part 3 to move up and down in the vertical direction, thereby allowing the hot pressing part 3 to be pressed down into the core material placement hole 2111, applying high temperature and high pressure to the core material to meet the vulcanization requirements, thereby achieving the connection of the two splicing sections.

[0033] Figure 3 This is a structural diagram of the upper pressure plate of a preferred embodiment of the utility model. Figure 1 、 Figure 2 as well as Figure 3 As shown, the upper pressing plate 21 further includes a bottom plate 211, a top plate 212, and a connecting plate 213. During assembly, the top plate 212 and the bottom plate 211 are arranged in an upper and lower layer, leaving space between the top and bottom plates 211, providing space for the subsequent installation and movement of the hot pressing part 3. At this time, a connecting plate 213 is set between the two sides of the top plate 212 and the bottom plate 211, and after connecting them, a rectangular frame is formed. The top plate 212, the bottom plate 211, and the two connecting plates 213 can form a rectangular frame structure, which has a higher overall structural strength. It can not only meet the subsequent use requirements of the first telescopic mechanism 41 after being pressed down and used in conjunction with the lower pressing plate 22, but also meet the installation and movement requirements of the hot pressing part 3. In addition, the core material placement hole 2111 is located on the bottom plate 211, so that the core material placement hole 2111 can be close to the lower pressing plate 22, which provides conditions for the core material to be placed in the gap between the ends of the two splicing sections pressed by the upper pressing plate 21 and the lower pressing plate 22 through the core material placement hole 2111. In addition, the hot pressing part 3 is set in the gap between the top plate 212 and the bottom plate 211, which can not only realize the rational use of space and ensure that the equipment space is smaller, but also enable the hot pressing part 3 to move relative to the upper pressing plate 21, that is, when the upper pressing plate 21 is pressed down and cooperates with the lower pressing plate 22 to press the splicing section to be spliced, the hot pressing part 3 can continue to press down a predetermined distance, and the core material located in the core material placement hole 2111 of the bottom plate 211 is subjected to high pressure and high temperature through the hot pressing part 3, thereby meeting the use requirements of vulcanization connection.

[0034] More specifically, the first telescopic mechanism 41 includes a first telescopic actuator 411 and a plurality of first guide members 412. During installation, the first telescopic actuator 411 is mounted on the mounting end 11 and arranged vertically downward. Simultaneously, the telescopic shaft of the first telescopic actuator 411 is fixedly connected to the top plate 212. When the first telescopic actuator 411 is actuated, the telescopic shaft of the first telescopic actuator 411 can drive the top plate 212 to move vertically upward and downward, thereby achieving vertical movement of the upper pressure plate 21. This allows the first telescopic actuator 411 to serve as a driving mechanism for the upper pressure plate 21. Furthermore, one end of the plurality of first guide members 412 is connected to the top plate 212, and the other end of the first guide members 412 is slidably mounted on the mounting end 11. This allows the first guide members 412 to slide on the mounting end 11 as the top plate 212 moves upward and downward, thereby maintaining the stability of the upper pressure plate 21 during its movement.

[0035] Similarly, the second telescopic mechanism 42 includes a second telescopic actuator 421 and a plurality of second guide members 422. During installation, the second telescopic actuator 421 is mounted on the mounting end 11 and arranged vertically downward. The telescopic shaft of the second telescopic actuator 421 is fixedly connected to the hot press 3. When the second telescopic actuator 421 is actuated, the telescopic shaft of the second telescopic actuator 421 can drive the hot press 3 to move vertically upward and downward, thereby achieving vertical upward and downward movement of the hot press 3, allowing the second telescopic actuator 421 to serve as a driving structure for the hot press 3. In addition, one end of the plurality of second guide members 422 is connected to the hot press 3, and the other end of the second guide member 422 is slidably mounted on the mounting end 11. When the hot press 3 is raised or lowered, it can be guided by the sliding movement of the second guide member 422 on the mounting end 11, thereby maintaining the stability of the hot press 3 during its raising or lowering. It is worth noting that an avoidance hole is also provided on the top plate 212 of the upper pressure plate 21. At this time, the hole axis of the avoidance hole is arranged parallel to the telescopic axis of the second telescopic driver 421, and the avoidance hole passes through the top plate 212. The telescopic axis of the second telescopic driver 421 is connected to the hot pressing part 3 after passing through the avoidance hole, ensuring that the telescopic axis of the second telescopic driver 421 will not be affected by the upper pressure plate 21 when driving the hot pressing part 3 to move, and the structural design is more reasonable.

[0036] More specifically, the first guide member 412 for guiding the upper pressure plate 21 and the second guide member 422 for guiding the hot pressing member 3 both include a guide rod and a guide sleeve. At this time, a through hole 2121 parallel to the second telescopic driver 421 is also provided on the top plate 212. During installation, the guide rod of the second guide member 422 is passed through the through hole 2121 and then slidably connected to the mounting end 11, so that the guide rod of the second guide member 422 will not be affected by the upper pressure plate 21 and can independently guide the hot pressing member 3, thereby adapting to the use requirements of the hot pressing member 3 relative to the upper pressure plate 21. In addition, a plurality of guide holes corresponding to the guide rods of the first guide member 412 and the second guide member 422 are opened on the mounting end 11, and the guide sleeves of the first guide member 412 and the second guide member 422 are installed in the corresponding guide holes. At the same time, the guide rods of the first guide member 412 and the second guide member 422 are slidably set in the corresponding guide sleeves, thereby realizing the sliding connection of the guide rods of the first guide member 412 and the second guide member 422 relative to the mounting end 11.

[0037] More specifically, a first position detection structure is provided on the frame 1 in the vertical direction. At the same time, a second position detection structure 5 is provided on the upper pressure plate 21. Moreover, the first position detection structure and the second position detection structure 5 both include mounting strips 51, a plurality of detection sensors 52 and a matching block 53. During installation, the mounting strips 51 of the first position detection structure and the second position detection structure 5 are arranged in the vertical direction and are respectively installed on the frame 1 and the upper pressure plate 21. At the same time, a number of corresponding sensors are arranged on each mounting strip 51 and spaced apart in the vertical direction, and matching blocks 53 are provided on the upper pressure plate 21 and the hot pressing part 3 and correspond to the sensors on the mounting strips 51 installed on the frame 1 and the upper pressure plate 21, respectively, so that the first position detection mechanism can serve as a limit monitoring structure for the upper pressure plate 21, and the second position detection mechanism can serve as a limit monitoring structure for the hot pressing part 3, so that when the upper pressure plate 21 and the hot pressing part 3 are performing lifting movements, position monitoring can be achieved through the matching blocks 53 thereon and the corresponding sensors, thereby improving safety protection performance. It is worth noting that the sensors include but are not limited to the photoelectric sensors commonly used on the market, which can meet the use requirements. The specific model selection is not repeated here.

[0038] More specifically, a number of heating holes 214 are provided in the lower pressing plate 22, the upper pressing plate 21 and the hot pressing part 3. At this time, the heating holes 214 of the upper pressing plate 21 are located on its bottom plate 211, and a heating structure 6 is provided in each heating hole 214. The heating structure 6 provides heat to the lower pressing plate 22, the bottom plate 211 of the upper pressing plate 21 and the hot pressing part 3 to meet the high-temperature vulcanization requirements. Preferably, the heating structure 6 can be an electric heating tube that can meet the needs of simple and fast heating. The specific model selection will not be repeated here. In addition, the heating holes 214 on the lower pressure plate 22, the upper pressure plate 21 and the hot pressing part 3 are all holes that pass through the two ends of the corresponding structures. The wiring terminal of the heating structure 6 is led out from one end of the heating hole 214. The other end of the heating hole 214 is provided with a covering plate and fixed by screws, which not only facilitates the processing of the heating hole 214 on the corresponding structure, but also facilitates the disassembly and assembly of the heating structure 6 from the heating hole 214, facilitating assembly and subsequent maintenance and repair.

[0039] More specifically, the core material placement hole 2111 on the bottom plate 211 of the upper pressing plate 21 is a stepped hole. At this time, the large-section hole of the core material placement hole 2111 is located on the side of the bottom plate 211 close to the top plate 212, so that the small-section hole of the core material placement hole 2111 is on the side close to the lower pressing plate 22. Preferably, the contour shape of the small-section hole of the core material placement hole 2111 is consistent with the external contour shape of the core material, thereby ensuring that the core material can be placed through the core material placement hole 2111 to determine the placement position. In addition, the operator can place the core material through the large-section hole of the core material placement hole 2111, that is, the opening of the core material placement hole 2111 is expanded, which facilitates the placement of the core material. In addition, the opening of the large-section hole and the opening of the small-section hole of the core material placement hole 2111 are both provided with guide slopes, which further facilitate the rapid and accurate placement of the core material in the core material placement hole 2111, and the structural design is more reasonable.

[0040] More specifically, the hot pressing part 3 includes a mounting plate 31 and a hot pressing block 32. During installation, the mounting plate 31 is arranged parallel to the bottom plate 211 and located between the top plate 212 and the bottom plate 211. The mounting plate 31 expands the installation area, providing a sufficiently large mounting carrier for the subsequent installation of the hot pressing block 32 and the second guide member 422, and also providing conditions for the subsequent use as a limit when the hot pressing part 3 is pressed down. At this time, the top surface of the mounting plate 31 is connected to the second telescopic mechanism 42, and the hot pressing block 32 is installed on the bottom surface of the mounting plate 31, so that the hot pressing block 32 can be installed on the second telescopic mechanism 42 through the mounting plate 31, so that the second telescopic mechanism 42 can drive the hot pressing block 32 to move. At the same time, the mounting plate 31 is connected to the guide rod of the second guide member 422, ensuring that the second guide member 422 can provide guidance for the movement of the hot pressing block 32. Furthermore, aligning the hot pressing block 32 vertically with the large-section hole of the core material placement hole 2111 provides the conditions for the hot pressing block 32 to subsequently enter the core material placement hole 2111 and apply high pressure and high temperature to the core material located in the small-section hole of the core material placement hole 2111. Preferably, the heating structure 6 in the hot pressing member 3 is provided on the hot pressing block 32, so that during heating, it can better contact the core material in the core material placement hole 2111, quickly achieving high-temperature heating. Furthermore, the downward pressure of the second telescopic mechanism 42 applies high pressure, achieving high-temperature, high-pressure vulcanization of the core material, thereby improving connection efficiency and reliability.

Figure 1 and Figure 4As shown, the frame 1 further includes two supporting side panels 13, a top mounting block, a bottom table, a number of protective plates 14, and a number of connecting rods 15. At this point, the two supporting side panels 13 are arranged in a "C" shape in the vertical direction with a gap between them, serving as the main support structure of the frame 1. At the same time, the top mounting block and the bottom table are both set in the gap between the two supporting side panels 13 and are located at the upper and lower parts of the supporting side panels 13, respectively. The two sides of the top mounting block and the bottom table are connected to the two supporting side panels 13 by threaded fasteners, respectively. At this point, the top mounting block and the bottom table form the mounting end 11 and the work station 12, respectively, that is, the telescopic mechanism 4 is mounted on the top mounting block, and the lower pressure plate 22 is mounted on the bottom table. In addition, a plurality of protective plates 14 are disposed within the gap between the two supporting side panels 13, and the gap between the edges of the two supporting side panels 13 is sealed. That is, the protective plates 14 also cover other locations between the two supporting side panels 13, so that the space between the two supporting side panels 13 can form a relatively independent space, providing internal space for the installation of wiring and control structures. In addition, a plurality of connecting rods 15 are disposed within the gap between the two supporting side panels 13, and their ends are fixedly connected to the two supporting side panels 13. Preferably, the ends of the connecting rods 15 are connected to the two supporting side panels 13 by threaded fasteners. The connecting rods 15 strengthen the connection strength between the two supporting side panels 13, thereby improving the integrity and structural strength of the frame 1.

[0042] The C-frame structure joint machine provided in this embodiment includes a frame 1, a pressing plate 2, a hot pressing piece 3 and a telescopic mechanism 4; a lower pressing plate 22 and an upper pressing plate 21 of the pressing plate 2 are respectively arranged on the work station 12 at the lower part of the frame 1 and the mounting end 11 at the upper part, and a telescopic mechanism 4 is arranged between the mounting end 11 and the upper pressing plate 21. At the same time, the telescopic mechanism 4 is also connected to the hot pressing piece 3, and a core material placement hole 2111 is opened on the upper pressing plate 21 and is directly opposite to the hot pressing piece 3 in the vertical direction, so that when the ends of the two splicing sections are extended into the upper pressing plate 21 and the lower pressing plate 22, it can be pressed by the upper pressing plate 21 and the lower pressing plate 22, and a gap opposite to the core material placement hole 2111 is left between the ends of the two splicing sections. The core material is placed in the gap between the two splicing sections through the core material placement hole 2111 and the hot pressing part 3 is pressed down to achieve high temperature and high pressure vulcanization, thereby realizing a direct connection between the two splicing sections.
