Description

Technical Field

[0001] This utility model belongs to the technical field of synchronous belt coupling, and in particular relates to a preheating mechanism for a synchronous belt coupling machine. Background Technology

[0002] In the production and maintenance of synchronous belts, the splicing of synchronous belts plays a decisive role. The unique toothed structure of synchronous belts results in significant inconsistencies in their thickness, posing a major challenge to the preheating process before splicing. Traditional preheating methods typically use hot air or steam to heat the synchronous belt. However, due to the toothed structure, hot air and steam can easily form airflow short circuits in the toothed areas, making it difficult for the deep parts of the toothed areas to receive sufficient heat. This uneven heating leads to inconsistent softening of the material in different parts of the synchronous belt during splicing, severely affecting the strength and reliability of the splice.

[0003] Therefore, this utility model designs a synchronous belt preheating mechanism to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this utility model is to provide a preheating mechanism for a synchronous belt connector, so as to solve the problem mentioned in the background art that, due to the setting of the tooth groove on the synchronous belt, hot air and hot steam are prone to airflow short circuit in the tooth groove, making it difficult for the deep part of the tooth groove to obtain sufficient heat, resulting in uneven heating.

[0005] This utility model is implemented as follows: a preheating mechanism for a synchronous belt connector includes a frame.

[0006] A column is installed on the top of the frame, and a crossbar is fixed on the side of the column. A sleeve is fitted on the crossbar, and a U-shaped frame is fixed at one end of the sleeve. A movable block is provided inside the U-shaped frame, and a pneumatic clamp is provided on the movable block.

[0007] The U-shaped frame is equipped with an adjustment mechanism, which is used to drive the movable block to move laterally.

[0008] The column is equipped with a lateral movement mechanism, which is used to drive the sleeve to move laterally.

[0009] A gantry frame is also fixed to the top of the frame, and an installation plate is fixed to the inner side of the gantry frame by a bracket. Cylinders are fixed through both ends of the top of the gantry frame, and a heating plate is fixed to the output end of the cylinder. Heat-conducting teeth are fixed to the bottom of the heating plate.

[0010] The frame is also equipped with a rotating mechanism, which is used to drive the column to rotate.

[0011] Preferably, the adjustment mechanism includes a lead screw, which is installed inside the U-shaped frame, and a motor is fixed outside the U-shaped frame. The output end of the motor is connected to the lead screw, and both ends of the lead screw pass through the movable block and are threadedly connected to it.

[0012] In the above technical solution, after the synchronous belt is preheated, since the two ends of the synchronous belt are in a separated and unconnected state, after the pneumatic clamp clamps the synchronous belt on the mounting plate, the motor drives the lead screw to rotate, so that the lead screw drives the two sets of movable blocks and the pneumatic clamp to move closer to each other. In this way, the two ends of the synchronous belt can be brought close to each other so that it can be placed in the coupling mold for coupling operation.

[0013] Preferably, the lateral movement mechanism includes a second motor, which is fixed to the column and its output end is connected to a second lead screw. The second lead screw is installed laterally on the side of the column and has a mounting block threaded onto it. The mounting block is fixedly connected to the sleeve.

[0014] In the above technical solution, after the pneumatic clamp holds the synchronous belt on the mounting plate, the second motor drives the second lead screw to rotate, which in turn drives the mounting block and the sleeve to move laterally. The crossbar supports and guides the sleeve. This technical solution can move the synchronous belt to the connecting mold for connecting operations after clamping the synchronous belt, in conjunction with the rotating mechanism. This eliminates the need for manual handling of the heated synchronous belt, improving work efficiency and preventing workers from being burned by the high-temperature synchronous belt.

[0015] Preferably, the heat-conducting teeth are provided in several groups.

[0016] In the above technical solution, several sets of heat-conducting teeth can uniformly heat the connection points at both ends of the synchronous belt.

[0017] Preferably, the rotating mechanism includes a motor three, which is fixed inside the frame, and a gear one is provided at the output end of the motor three. A gear two is sleeved on the outside of the column, and the gear two meshes with the gear one.

[0018] In the above technical solution, the motor drives the gear one to rotate, which in turn drives the gear two and the column to rotate. This allows the synchronous belt to be preheated and clamped before being transferred to the docking equipment position so that it can be placed in the docking mold.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) By setting up an installation plate in conjunction with the cylinder to drive the heating plate down, the heat-conducting teeth at the bottom of the heating plate can mesh with the tooth groove of the synchronous belt, preventing the synchronous belt from collapsing at the joint due to bending. Then, the joint of the synchronous belt can be preheated by the heating plate and the heat-conducting teeth. This technical solution can precisely mesh with the tooth groove of the synchronous belt. This design allows heat to be transferred to the teeth of the synchronous belt more directly and efficiently, avoiding the problem of uneven local heating that may occur in traditional heating methods, ensuring that the entire end of the synchronous belt is heated evenly. Furthermore, by adjusting the specifications of the heat-conducting teeth, it can adapt to the preheating requirements of synchronous belts of different specifications and types, and has broad application prospects.

[0021] (2) Since the synchronous belt can move under the heat-conducting teeth, it is convenient for the staff to install several sets of synchronous belts under the heating plate in sequence to achieve centralized heating of several sets of synchronous belts. It is also convenient to transfer the synchronous belt to the docking mold for docking after preheating by pneumatic clamps, avoiding direct contact between the manual and the high temperature synchronous belt, reducing the operation risk. At the same time, the precise clamping action can accurately place the synchronous belt in the docking mold, improving the accuracy and convenience of operation. Attached Figure Description

A movable block 6 is provided inside the U-shaped frame 5, and a pneumatic clamp 7 is provided on the movable block 6.

[0031] The U-shaped frame 5 is equipped with an adjustment mechanism 8, which is used to drive the movable block 6 to move laterally.

[0032] The column 2 is equipped with a horizontal movement mechanism 9, which is used to drive the sleeve 4 to move laterally;

[0033] A gantry frame 10 is fixed to the top of the frame 1, and a mounting plate 12 is fixed to the inner side of the gantry frame 10 through a bracket 11. A cylinder 13 is fixed through both ends of the top of the gantry frame 10, and a heating plate 14 is fixed to the output end of the cylinder 13. A heat-conducting tooth is fixed to the bottom of the heating plate 14.

[0034] The frame 1 is also equipped with a rotating mechanism 15, which is used to drive the column 2 to rotate.

[0035] Please see Figure 1-2 In this embodiment: the adjusting mechanism 8 includes a lead screw 801, which is installed inside the U-shaped frame 5, and a motor 802 is fixed on the outside of the U-shaped frame 5. The output end of the motor 802 is connected to the lead screw 801, and both ends of the lead screw 801 pass through the movable block 6 and are threadedly connected to it.

[0036] Please see Figure 1-2 In this embodiment: the transverse mechanism 9 includes a second motor 901, which is fixed on the column 2, and the output end of the second motor 901 is connected to a second lead screw 902. The second lead screw 902 is installed laterally on the side of the column 2, and a mounting block 903 is threadedly connected to the second lead screw 902. The mounting block 903 is fixedly connected to the sleeve 4.

[0037] Please see Figure 3 In this implementation: several sets of heat-conducting teeth are provided.

[0038] Please see Figure 1 In this embodiment: the rotating mechanism 15 includes a motor 1501, which is fixed inside the frame 1. The output end of the motor 1501 is provided with a gear 1502. The outside of the column 2 is fitted with a gear 1503, which meshes with the gear 1502.

[0039] The working principle and usage process of this utility model are as follows: During use, the operator places the two ends of the synchronous belt on the mounting plate 12. Then, the cylinder 13 is opened to lower the heating plate 14, causing the heat-conducting teeth at the bottom of the heating plate 14 to engage with the tooth grooves on the synchronous belt. The heating plate 14 does not press the synchronous belt tightly. The operator can then push the synchronous belt below the heat-conducting teeth, allowing it to slide on the mounting plate 12. More synchronous belts to be connected can be inserted between the heat-conducting teeth and the mounting plate 12. The heating plate 14 can then be opened for heating. Once the heat-conducting teeth are heated, the synchronous belt will be preheated. Because the heat-conducting teeth can precisely engage with the tooth grooves of the synchronous belt, the heat can be transferred more directly and efficiently to the teeth of the synchronous belt. After the synchronous belt is preheated, the motor 901 can be turned to rotate the lead screw 902, causing the lead screw 902 to extend the mounting block 903 and the sleeve 4. The sleeve 4 will then move the U-shaped frame 5 and the pneumatic clamp 7 into the gantry frame 10. The synchronous belt on the mounting plate 12 can be clamped by the pneumatic clamp 7. After clamping, the motor 2 901 is turned on to drive the lead screw 2 902 to rotate, so that the lead screw 2 902 drives the mounting block 903 and the sleeve 4 to move closer to the column 2. At the same time, the pneumatic clamp 7 will pull the synchronous belt out from between the heat-conducting teeth and the mounting plate 12. Then, the motor 3 1501 is turned on to drive the gear 1502 to rotate, so that the gear 1502 drives the gear 2 1503 and the column 2 to rotate, and drives the crossbar 3 and the sleeve 4 to rotate horizontally, so as to move the preheated synchronous belt to the docking equipment for docking. Since the docking ports of the synchronous belt are separated when it is preheated, before placing the synchronous belt in the docking mold, the motor 1 802 can be turned on to drive the lead screw 1 801 to rotate, so that the lead screw 1 801 drives the two sets of movable blocks 6 and the pneumatic clamp 7 to move closer to each other. In this way, the docking ports of the synchronous belt can be brought closer to each other, so as to facilitate its placement in the docking mold.
