Description

Technical Field

[0001] This utility model relates to the field of belt processing equipment technology, and in particular to an end-point fixing device for industrial transmission belt processing. Background Technology

[0002] Industrial belts require the cut ends to be fixed together during processing to create a closed loop structure. The key requirements for fixing the ends of industrial belts are ensuring joint strength, matching the tensile strength of the belt body to prevent breakage, eliminating noticeable protrusions or gaps, preventing jamming and wear, and ensuring smooth belt operation.

[0003] However, in actual processing, a heat-fusion joint is typically used. This involves heating the belt end points until the rubber is in a molten state, then cross-linking and fusing with the vulcanized rubber. A vulcanizing machine is then used to pressurize the end points, and after cooling, a single joint is formed, ensuring a strong connection between the belt end points. However, using a heat-fusion joint not only requires heating but also stopping heating during cooling and demolding. Pressure must be released after the temperature drops below 60°C, the vulcanizing machine removed, and excess rubber trimmed from the joint edges, significantly increasing processing difficulty. Therefore, we propose an end-point fixing device for industrial transmission belts that can reduce processing difficulty. Utility Model Content

[0004] The purpose of this invention is to address the problem of the high operational difficulty of the hot-melt joint method in the background art, and to propose an end-point fixing device for industrial transmission belt processing that can reduce processing difficulty.

[0005] The technical solution of this utility model: An end-point fixing device for processing industrial transmission belts, including a base, a U-shaped assembly frame fixedly installed on the top of the base, and several belt sleeve interfaces cut out on the U-shaped assembly frame, and further including:

[0006] A support plate is fixedly installed on a U-shaped assembly frame. A long strip-shaped opening is cut into the support plate, and a belt limiter is movably inserted into the long strip-shaped opening. A belt limiter is fixedly installed on the top of the support plate and on one side of the belt limiter by bolts. A first adjusting screw is movably inserted through the support plate, and one end of the first adjusting screw passes through the belt limiter and is threadedly connected to it.

[0007] A tray is fixedly installed on the top of a U-shaped assembly frame. A pressing component is slidably installed on the tray, and a pressure roller is rotatably installed on the pressing component. The pressure roller is used for pressurizing and curing the adhesive surface at the belt joint.

[0008] Optionally, an I-shaped connecting plate is fixedly installed on one side of the belt limiting frame. The I-shaped connecting plate is movably fitted onto several limiting rods fixed between the base and the support plate. One end of the first adjusting screw passes through the I-shaped connecting plate and is threadedly connected to it.

[0009] Optionally, the top of the U-shaped assembly frame is threaded with two second adjusting screws, the bottom end of which is inserted into a matching belt sleeve interface and rotatably mounted with a belt positioning plate.

[0010] Optionally, the pressing assembly includes an external U-shaped frame, which is slidably mounted on the pallet, and an internal U-shaped frame is slidably mounted on the inner side of the external U-shaped frame, with the pressure roller rotatably mounted on the inner side of the internal U-shaped frame.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, this utility model proposes an end-point fixing device for industrial transmission belt processing, including a base 1. A U-shaped assembly frame 2 is fixedly installed on the top of the base 1. A belt sleeve interface 21 is cut out on the U-shaped assembly frame 2. When the end-point fixing processing of the belt is required, the belt to be assembled 10 is wrapped into a ring and sleeved on the belt sleeve interface 21 for easy feeding. A support plate 9 is fixedly installed on the U-shaped assembly frame 2. A long strip-shaped through-hole 91 is cut out on the support plate 9. The top of the belt limiting frame 4 passes through the long strip-shaped through-hole 91 and extends to the top of the support plate 9. A belt limiting plate 92 is provided on the top of the support plate 9 and on one side of the belt limiting frame 4. The belt limiting plate 92 is fixed by bolts inserted into the bottom of the support plate 9 to ensure that the belt to be assembled 10 can be tightly clamped in the belt limiting plate 92. The position between the positioning plate 92 and the belt limiting frame 4; a first adjusting screw 3 is movably inserted on the support plate 9, one end of the first adjusting screw 3 passes through the belt limiting frame 4 and is threaded to it, by rotating the first adjusting screw 3, the belt limiting frame 4 can be raised and lowered, which is convenient for adjusting the height of the top of the belt limiting frame 4; since the belt limiting plate 92 is fixed by bolts, it is convenient to disassemble and replace belt limiting plates 92 of different thicknesses, and the height of the top of the belt limiting frame 4 can be adjusted according to the thickness of the belt 10 to be assembled, and the belt limiting plate 92 can be replaced, ensuring that the top height of the belt limiting frame 4 and the belt limiting plate 92 are both lower than the top height of the belt 10 to be assembled, so as to reserve sufficient downward pressure space for the subsequent pressing treatment of the belt 10 to be assembled, which is suitable for processing belts of different thicknesses.

[0032] A tray 5 is fixedly mounted on the top of the U-shaped assembly frame 2. A pressing component 7 is slidably mounted on the tray 5. A pressure roller 74 is rotatably mounted on the pressing component 7. A first cylinder 6 is fixedly mounted on the top of the tray 5 and on one side of the pressing component 7. The output end of the first cylinder 6 is fixedly connected to the pressing component 7. When the pressure roller 74 presses on the upper surface of the joint of the belt 10 to be assembled, the first cylinder 6 drives the pressure roller 74 to roll along the upper surface of the belt. During this process, the chemical bonding effect of the cold vulcanizing adhesive (containing curing agent) is used to bond the end of the belt 10 to be assembled to the joint film (or belt body). No heating is required. Combined with the pressure applied to the joint by the pressure roller 74, the curing effect of the adhesive at the end of the belt 10 to be assembled can be accelerated, ensuring that the adhesive and the film are tightly connected, and effectively improving the firmness of the end connection.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in order to facilitate the height adjustment of the belt limit frame 4, an I-shaped connecting plate 41 is fixedly installed on one side of the belt limit frame 4, and several limiting rods are fixedly installed between the base 1 and the support plate 9. The I-shaped connecting plate 41 is movably sleeved on the several limiting rods, which can limit the horizontal movement of the I-shaped connecting plate 41, thereby improving the stability of the belt limit frame 4 when it is raised and lowered. The bottom end of the first adjusting screw 3 passes through the I-shaped connecting plate 41 and is threaded to it. When the first adjusting screw 3 is rotated, the belt limit frame 4 can be raised and lowered, which effectively improves the convenience of adjusting the height of the belt limit frame 4.

[0034] Furthermore, to ensure the stability of the two ends of the belt being close to each other, two second adjusting screws 8 are threadedly installed on the top of the U-shaped assembly frame 2. The bottom end of the second adjusting screw 8 is inserted into the belt sleeve interface 21 provided below it and a belt positioning plate 81 is rotatably installed thereon. By rotating the second adjusting screw 8 and driving the belt positioning plate 81 to move downward, the belt 10 to be assembled can be clamped and fixed on the top of the support plate 9, ensuring that the two ends of the belt 10 to be assembled can be in a stable close-to-each-other state.

[0035] Secondly, in order to prevent the belt positioning plate 81 from rotating along with the second adjusting screw 8, a groove is cut into the inner wall of the belt sleeve interface 21 at the installation location of the belt positioning plate 81. The slider at the end of the belt positioning plate 81 is slidably installed in the groove, which can limit the belt positioning plate 81 in the horizontal direction and effectively prevent the belt positioning plate 81 from rotating when it moves up and down.

[0036] like Figure 1 and Figure 3 As shown, in order to ensure that the pressure roller 74 can roll along the top of the joint end of the belt 10 to be assembled, the outer U-shaped frame 71 of the pressing component 7 is slidably installed on the support plate 5, and the inner U-shaped frame 73 is slidably installed on the inner side of the outer U-shaped frame 71. The pressure roller 74 is rotated and installed on the inner U-shaped frame 73. The output end of the first cylinder 6 is fixedly connected to the outer U-shaped frame 71. By driving the outer U-shaped frame 71 to move laterally through the first cylinder 6, the pressure roller 74 can be driven to roll along the top of the belt 10 to be assembled.

[0037] Furthermore, in order to ensure that the pressure roller 74 can be tightly pressed against the top of the belt 10 to be assembled, a second cylinder 72 is fixedly installed on the top of the external U-shaped frame 71. The output end of the second cylinder 72 is fixedly connected to the top of the internal U-shaped frame 73. The internal U-shaped frame 73 is moved downward by the second cylinder 72 to ensure that the pressure roller 74 can follow the downward movement, so as to tightly press the pressure roller 74 against the top of the belt 10 to be assembled.

[0038] Secondly, in order to ensure that the built-in U-shaped frame 73 can move laterally, a long strip opening 51 is cut on the pallet 5. The built-in U-shaped frame 73 and the pressure roller 74 both pass through the long strip opening 51 and extend to the bottom of the pallet 5. When the first cylinder 6 drives the external U-shaped frame 71 to move laterally, the built-in U-shaped frame 73 can move laterally in the area inside the long strip opening 51.

[0039] In this embodiment, the belt to be assembled 10 is first wrapped into a ring structure and fitted onto the belt sleeve interface 21. The second adjusting screw 8 is rotated and the belt positioning plate 81 is moved downward, thus fixing the belt to be assembled 10, which is wrapped into a ring structure, on the top of the support plate 9. At this time, the two ends of the belt to be assembled 10 are in a stable, close-to-each-other state. Cold vulcanizing adhesive containing curing agent is applied to the inclined surfaces at both ends of the belt to be assembled 10. At this time, a certain gap is left between the two adhesive surfaces. The cut joint adhesive is inserted into the gap to ensure that the joint adhesive can contact the two adhesive surfaces. The belt limiting frame 4 and the belt limiting plate 92 are used to clamp and limit the joint end of the belt to be assembled 10 to prevent misalignment of the two ends and ensure that the two joint ends can be accurately connected as one.

[0040] The second cylinder 72 drives the pressure roller 74 to move downward, ensuring that the pressure roller 74 can tightly press against the top of the joint of the belt 10 to be assembled. During this process, the first cylinder 6 drives the external U-shaped frame 71 to move laterally, which facilitates the pressure roller 74 to roll along the top of the belt 10 to be assembled. With the pressure applied by the pressure roller 74, air bubbles in the rubber surface at the end of the belt 10 to be assembled can be discharged, enhancing the adhesion between the rubber surface and the joint rubber sheet. After standing at room temperature for two hours, when the adhesive on the rubber surface has cured, it can be ensured that the two ends of the belt 10 to be assembled are firmly connected as one. The cold vulcanization joint treatment method eliminates the need for heat melting treatment of the belt, which is simple to operate and effectively reduces the difficulty of belt processing.

[0041] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
