Description

Technical Field

[0001] This utility model relates to the field of synchronous belt connector technology, and in particular to a synchronous belt connector machine. Background Technology

[0002] Hot vulcanization is the most widely used vulcanization method in rubber processing. It utilizes media such as steam, hot air, hot water, or electric heating to heat and vulcanize rubber products. Therefore, synchronous belts often use hot vulcanization for splicing due to its high efficiency and stable, long service life. However, existing hot vulcanization splicing machines for synchronous belts cannot limit the movement on both sides of the splice, resulting in unevenness on both sides of the splice after splicing. This affects the operational stability and lifespan of the synchronous belt. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a synchronous belt splicing machine. This solves the technical problem that the existing synchronous belt hot vulcanizing splicing machine cannot limit the two sides of the joint when splicing synchronous belts, which will result in the synchronous belts being uneven on both sides after splicing, thus affecting the running stability and lifespan of the synchronous belts.

[0004] To achieve the above-mentioned technical objectives, the present invention provides a synchronous belt splicing machine, including an upper mold and a lower mold. The upper mold has an upper heating component at its bottom and a lower heating component at its top. Two limiting plates are provided above the lower mold, and fixing rods are installed on both sides of the lower mold. The two ends of the limiting plates are fixedly connected to the two fixing rods by first bolts and first nuts, respectively. The fixing rods have strip-shaped fixing holes along their length direction. The first bolts can move inside the strip-shaped fixing holes, thereby allowing the limiting plates to move along the length direction of the lower mold to restrict the splice of the synchronous belt between the two limiting plates.

[0005] Furthermore, both ends of the limiting plate are provided with first fixing holes, and the screw end of the first bolt passes through the strip-shaped fixing hole and the first fixing hole in sequence to be fixedly connected to the first nut.

[0006] Furthermore, the longitudinal section of the strip-shaped fixing hole is an inverted "T" shape, and the first bolt is an external hexagonal nut that matches the strip-shaped fixing hole.

[0007] Furthermore, each of the two fixed rods is equipped with a pressure rod above it, and the two ends of the pressure rod are fixedly connected to the two fixed rods by a second bolt and a second nut.

[0008] Furthermore, both ends of the fixing rod are provided with second fixing holes, and both ends of the pressure rod are provided with third fixing holes. The screw end of the second bolt passes through the second fixing hole and the third fixing hole in sequence and is threadedly connected to the second nut.

[0009] Furthermore, the second bolt is an external hexagonal bolt, and the third fixing hole is a hexagonal through hole that mates with the second bolt.

[0010] The beneficial effects of this utility model include: This utility model provides a synchronous belt splicing machine, in which the first bolt can move inside the strip-shaped fixing hole, thereby allowing the limiting plate to move along the length direction of the lower mold to restrict the synchronous belt between the two limiting plates. Therefore, the synchronous belt will be neat on both sides of the splice after splicing, improving the running stability and life of the synchronous belt. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] This utility model embodiment provides a synchronous belt connector machine, such as Figure 1 The device includes an upper mold 1 and a lower mold 2. The upper mold 1 has an upper heating component at its bottom and a lower heating component at its top. The lower mold 2 has limiting plates 3 at both ends above it. The lower mold 1 has fixing rods 4 installed on both sides. The two ends of the limiting plates 3 are fixedly connected to the two fixing rods 4 by first bolts 5 and first nuts 6, respectively. At the same time, the fixing rods 4 have strip-shaped fixing holes 41 along their length. The first bolts 5 can move inside the strip-shaped fixing holes 41, so that the limiting plates 3 can move along the length of the lower mold 2 to restrict the joint of the synchronous belt between the two limiting plates 3. Therefore, the synchronous belt will be neat on both sides after the joint, improving the running stability and life of the synchronous belt.

[0018] It should be noted that in this embodiment, the two ends of the two limiting plates 3 are fixedly connected to the two fixing rods 4 by the first bolts 5 and the first nuts 6, respectively. This allows both limiting plates 3 to move along the length of the lower mold 2, thereby restricting the joint of the timing belt between the two limiting plates 3. This utility model is not limited to the above design. For example, in some other embodiments, one limiting plate 3 is fixedly installed above the upper mold 2, while the two ends of the other limiting plate 3 are fixedly connected to the two fixing rods 4 by the first bolts 5 and the first nuts 6, respectively. This allows one limiting plate 3 to move along the length of the lower mold 2, and also restricts the joint of the timing belt between the two limiting plates 3.

[0019] In this embodiment, as Figure 2-3 As shown, both ends of the limiting plate 3 are provided with first fixing holes 31. The screw end of the first bolt 5 passes through the strip-shaped fixing hole 41 and the first fixing hole 31 in sequence and is fixedly connected to the first nut 6. The above method can easily fix the limiting plate 3 to the fixing rod 4, and can also easily disassemble the limiting plate 3. Thus, different thicknesses of limiting plates 3 can be selected and installed according to the different thicknesses of the synchronous belt, or limiting plates 2 of the same thickness can be stacked together to meet the needs of limiting synchronous belts of different thicknesses. At the same time, the longitudinal section of the strip-shaped fixing hole 41 is an inverted "T" shaped structure. The first bolt 5 is an external hexagonal nut that matches the strip-shaped fixing hole 41. The head of the first bolt 5 can be restricted to the bottom of the inverted "T" shaped strip-shaped fixing hole 41. When the limiting plate 3 and the fixing rod are fixed or loosened, the first screw 6 can be adjusted. The first nut 6, when adjusting the first nut 6, the strip-shaped fixing hole 41 can restrict the rotation of the first bolt 5, making operation more convenient. This utility model is not limited to the above design. For example, in some other embodiments, the limiting plate 3 has a first fixing hole 31 at both ends. The screw end of the first bolt 5 passes through the first fixing hole 31 and the strip-shaped fixing hole 41 in sequence and is fixedly connected to the first nut 6. At the same time, the longitudinal section of the strip-shaped fixing hole 41 is an inverted "T" shaped structure. The first nut 6 is a hexagonal nut that matches the strip-shaped fixing hole 41. The first nut 6 can be restricted at the bottom of the inverted "T" shaped strip-shaped fixing hole 41. When the limiting plate 3 and the fixing rod 4 are fixed or loosened, the first bolt 5 can be adjusted. At the same time, when adjusting the first bolt 5, the strip-shaped fixing hole 41 can restrict the rotation of the first nut 6, making operation more convenient.

[0020] In this embodiment, a pressure rod 7 is provided above each of the two fixed rods 4. The two ends of the pressure rod 7 are fixedly connected to the fixed rod 4 by a second bolt 8 and a second nut 9. The timing belt connector can be clamped between the pressure rod 7 and the fixed rod 4 by the cooperation of the second bolt 8 and the second nut 9, so as to prevent the timing belt connector from loosening during the connection process.

[0021] In this embodiment, as Figure 3-4As shown, the fixing rod 4 has a second fixing hole 42 at both ends, and the pressure rod 7 has a third fixing hole 71 at both ends. The screw end of the second bolt 8 passes through the second fixing hole 42 and the third fixing hole 71 in sequence and is threadedly connected to the second nut 9. The second bolt 8 is an external hexagonal bolt, and the second fixing hole 42 is a hexagonal through hole that mates with the second bolt. When the pressure rod 7 and the fixing rod 4 are fixed or loosened, the second nut 9 can be rotated. At the same time, when the second nut 9 is rotated, the second fixing hole 42 can restrict the rotation of the second bolt 8, making the operation more convenient. This utility model is not limited to the above design. For example, in some other embodiments, the second nut 9 is a hexagonal nut, and the third fixing hole 71 is a hexagonal through hole that mates with the second nut 9. When the pressure rod 7 and the fixing rod 4 are fixed or loosened, the second bolt 8 can be rotated. At the same time, when the second bolt 8 is rotated, the third fixing hole 71 can restrict the rotation of the second nut 9, making the operation more convenient.

[0022] Specific principle: When splicing the synchronous belt, the limiting plate 3 and the pressure rod 7 are loosened. After the limiting plate 3 and the pressure rod 7 are loosened, the two ends of the synchronous belt are passed through the two pressure rods 7 and the two fixing rods 4 respectively and connected. After the two ends of the synchronous belt are connected, the limiting plate 3 is moved to restrict the joint of the synchronous belt between the two limiting plates 3, and the limiting plate 3 is fixed by the first bolt 5 and the first nut 6. The synchronous belt joint is clamped and fixed between the pressure rod 7 and the fixing rod 4 by the second bolt 8 and the first nut 9. After the fixing is completed, the upper mold 1 is placed on the lower mold 2 for splicing.

[0023] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
