Abstract
Description
Technical Field
[0001] This utility model relates to a flat transmission belt joint device, specifically a water-cooled joint machine. Background Technology
[0002] Flat drive belts are widely used in industries such as textiles, printing, and packaging as a type of power transmission belt. They are an irreplaceable form of power transmission, with a large market demand and a wide variety of types and sizes. After the finished flat drive belt rolls come off the production line, they are mostly rolls with a length of more than 100 meters and a width of about 600 mm. They need to be pre-cut and processed to the required specifications according to the product model of the customer's order. Then, according to the process conditions, they are spliced. The strength of the splice meets more than 70% of the belt body, which can effectively guarantee the use conditions and become a ring-shaped flat drive belt that the customer can install and use. Utility Model Content
[0003] To solve the above problems, this utility model provides a water-cooled connector machine, which grinds and overlaps or inserts toothed ends of flat transmission belts of different specifications and sizes, and then performs heat sealing on the machine to quickly cool and shape them into a ring-shaped finished belt.
[0004] This utility model provides a water-cooled jointing machine. The two ends of the strip joint to be processed are spliced and placed into matching joint templates for fixation, ensuring the parallelism and thickness accuracy of the strip joint. The joint template for the strip to be joined is placed between two heating plates. Two handle-operated clamping nuts are adjusted to tighten the top and bottom of the joint template, maintaining appropriate clamping force. The manual directional valve of the compressed air line is opened to blow out residual water from the aluminum plate, avoiding any impact on the heating effect. Then, the upper plate airbag is inflated to 2.5 bar to ensure uniform pressure on the joint template and the strip joint. The temperature control instrument sets the joint process temperature and time, and the automatic control instrument sets the heating time. After the joint is heated, the automatic control solenoid valve opens, and cooling water is used for rapid cooling and shaping until the temperature drops below 60°C. The upper plate is then opened, the template is removed, and the product joint is complete.
[0005] The technical solution adopted by this utility model is as follows:
[0006] A water-cooled connector machine includes a connector template that clamps a belt to be connected; the connector template is symmetrically provided with an upper plate with water holes on its upper surface and a lower plate with water holes on its lower surface; heating plates are respectively provided inside the upper plate with water holes and the lower plate with water holes.
[0007] Furthermore, a lower heating plate is installed inside the lower plate with water holes; a lower insulation plate is installed below the lower heating plate to facilitate the transfer of heating heat to the lower plate with water holes and prevent the heat from being transferred downwards; an upper heating plate is installed inside the upper plate with water holes, and an upper insulation plate is installed above the upper heating plate to facilitate the transfer of heating heat to the upper plate with water holes and prevent the heat from being transferred upwards.
[0008] Furthermore, temperature sensor holes are respectively installed inside the upper plate and the lower plate with water holes; the water cooling system of the upper plate and the lower plate with water holes has interconnected closed channels at all four sides, the upper plate water inlet on the back of the upper plate with water holes and the lower plate water outlet on the lower plate with water holes are connected to the circulating water pipe, and the solenoid valve controls the flow of cooling water.
[0009] Furthermore, the upper plate with water holes is connected to the upper cover; the upper cover is a frame; from top to bottom, an adjustment assembly, an inflatable airbag, an upper protective plate, and an upper support plate are sequentially arranged between the top of the upper cover and the upper plate with water holes; the adjustment assembly is connected to the upper heating plate through a tension spring passing through the upper protective plate, upper support plate, and upper insulation plate. The upper plate with water holes can move up and down with the upper cover. The inflatable airbag facilitates the clamping of the joint template. The inflatable airbag pressurization device is sealed with a high-temperature resistant rubber tube, and then an inflation nozzle is installed and connected to the compressed air pipeline. The process pressure value can be adjusted by a pressure reducing valve, and a three-position five-way manual reversing valve can realize the inflation and deflation of the airbag.
[0010] Furthermore, a lower base is provided below the lower plate with water holes, and the lower base is a frame. Inside the lower base, a lower support plate and a lower protective plate are sequentially connected to the lower plate with water holes.
[0011] Furthermore, a rear axle pin assembly and a lower axle pin assembly are fixedly installed on both sides of the lower base, respectively; the rear axle pin assembly controls the opening and closing of the upper cover, and the other side of the upper cover is connected to the lower axle pin assembly.
[0012] Furthermore, the adjusting screw, fastening seat, and clamping nut of the lower shaft pin assembly can be used to open or fix the upper cover. The clamping nut can adjust the parallelism of the upper plate with water holes, the lower plate with water holes, and the joint template; adjusting the tightness of the two clamping nuts and the fastening seat appropriately ensures the consistency of the flat belt thickness with the original belt.
[0013] Furthermore, the joint template includes a joint mold cover plate and a matching mold base, with the flat strip product placed in the middle of the joint template.
[0014] Furthermore, a handle is installed on the side of the upper seat cover.
[0015] Furthermore, there are four tension springs; the airbag is equipped with an airbag nozzle opening located in the middle of the airbag and the upper cover.
[0016] Beforehand, place the two ends of the flat belt product to be spliced (the splice ends are ground or toothed according to the product process requirements) into the lower seat of the splice mold to overlap, and press and fix the splice mold cover plate; loosen the two clamping nuts, pull up the handle to open the upper plate with water holes, place the splice template on the middle part of the lower plate with water holes, and observe and align it; pull down the handle to press the upper plate with water holes on top of the splice template, and adjust the locking nuts to adjust the parallelism of the upper plate with water holes, the lower plate with water holes and the splice template; adjust the tightness of the two clamping nuts and the fastening seat to a moderate degree to ensure that the thickness of the flat belt body is consistent with the original belt body.
[0017] The three key elements of the jointing process are temperature, time, and pressure. Temperature control is achieved through two dedicated temperature controllers, an upper heating plate, a lower heating plate, and upper and lower temperature sensors. Time control allows for the free setting of heating and cooling periods based on temperature commands from the temperature controllers. The pressure control of the inflation bladder is achieved by adjusting the pressure reducing valve in the compressed air pipeline, followed by manual directional valves to ensure uniform pressure distribution to the joint template. After the jointing process is completed, the time controller automatically opens the water circuit solenoid valve, allowing the joint template to cool and solidify rapidly. The valve automatically closes when the temperature drops below 60°C, completing the flat strip product jointing process.

Detailed Implementation
[0025] The present invention will be further described below with reference to the accompanying drawings.
[0026] In this embodiment, the water-cooled connector machine uses perforated aluminum plates (upper plate 09 and lower plate 06) with dimensions of 280x260x20mm. The inlet 21 on the upper plate and the outlet 26 on the lower plate both have a diameter of 10mm. The connector template has dimensions of 280x200x15mm, satisfying the requirement that the maximum width of the flat strip product 30 connector is 180mm, or a combination of widths for similar flat strips, with a minimum inner circumference of 650mm. The effective length of the connector strip body 31 is 80 or 120mm depending on the process. The upper and lower heating plates 16 and 07 have power ratings of 1.5kW and 1.8kW, respectively. The lower insulation plate 05 and upper insulation plate 15 are made of flame-retardant and heat-insulating vermiculite.
[0027] The joint template 08 includes a joint mold cover plate 29 and a matching mold base 32, with the flat strip product 30 placed in the middle of the joint template.
[0028] A water-cooled connector machine includes a connector template 08 that clamps a tape to be connected. The connector template 08 is symmetrically arranged with an upper plate 09 with water holes on its upper surface and a lower plate 06 with water holes on its lower surface. A lower heating plate 07 is arranged inside the lower plate 06. A lower insulation plate 05 is arranged below the lower heating plate 07 to isolate the heat transfer of the lower heating plate, which is conducive to the transfer of heating heat to the lower plate with water holes and prevents the heat from being transferred downward. An upper heating plate 16 is arranged inside the upper plate 09 with water holes, and an upper insulation plate 15 is arranged above the upper heating plate 16 to isolate the heat transfer of the upper heating plate, which is conducive to the transfer of heating heat to the upper plate with water holes and prevents the heat from being transferred upward.
[0029] Temperature sensor holes are installed inside the upper and lower plates with water holes. The four sides of the upper and lower plates with water holes are equipped with interconnected closed channels. The upper plate inlet and the lower plate outlet are connected to the circulating water pipe. The solenoid valve controls the flow of cooling water.
[0030] The upper plate 09 with water holes is connected to the upper cover 18; the upper cover 18 is a frame; between the top of the upper cover and the upper plate 09 with water holes, an adjustment assembly 20, an inflatable airbag 17, an upper protective plate 10, and an upper support plate 14 are arranged sequentially from top to bottom; the inflatable airbag 17 has an inflatable airbag nozzle 23 with an opening in the middle position between the inflatable airbag and the upper cover. The adjustment assembly 20 is connected to the upper heating plate 16 through two tension springs 19 that pass through the upper protective plate 10, the upper support plate 14, and the upper insulation plate 15. The upper plate with water holes can move up and down with the upper cover 18. When the inflatable airbag is inflated, the tension springs are tightened, pressing the product joint position in the joint template; when the pressure inside the inflatable airbag is released, the tension springs return to their original position.
[0031] A lower base 01 is installed below the lower plate 06 with water holes. The lower base is a frame. Inside the lower base 01, a lower support plate 04 and a lower protective plate 02 are installed, which are connected in sequence to the lower plate 06 with water holes.
[0032] The lower base 01 has a rear axle pin assembly 27 and a lower axle pin assembly 03 fixedly installed on both sides. Pulling the handle 28 installed on the side of the upper cover connects the rear axle pin assembly 27 to the upper cover 18 via the fixed seat 24 on the rear axle pin assembly 27. As the rear axle pin assembly rotates, it drives the upper cover 18 to move up and down, thereby opening and closing the upper plate 09 with water holes. The fastening nut 25 is used to adjust the tightness with the fixed seat.
[0033] The other side of the upper cover 18 is connected to the lower shaft pin assembly 03. The adjusting screw 13, fastening seat 11, and clamping nut 12 of the lower shaft pin assembly cooperate to open or fix the upper cover. The clamping nut can adjust the parallelism of the upper plate with water holes, the lower plate with water holes, and the joint template; adjust the tightness of the two clamping nuts and the fastening seat to ensure that the thickness of the flat belt body is consistent with the original belt body.
[0034] The specific steps are as follows:
[0035] 1. Check the power supply (220V), air supply (2.5bar), and water pressure (2bar); loosen the clamping nut 12 and open the upper plate with water hole 09;
[0036] 2. After splicing the two ends of the joint, place it in the groove 32 of the mold base. If the width is insufficient, use a spare of the same type of product to make up the difference to prevent the joint from slipping. Then cover the joint mold cover plate 29 and fix the two ends. Press the joint part firmly and without gaps to ensure the dimensional accuracy of the joint.
[0037] 3. Place the prepared joint template 08 in the middle of the lower plate 06 with water holes, pull down the upper plate 09 with water holes, and tighten the locking nut 12 appropriately; press the manual pneumatic reversing valve, inflate the air bag 17 evenly, and press the joint mold and product joint part evenly; rotate the reversing valve to blow out the water holes in the upper and lower plates with water holes; then turn off the air source and inflate the air bag 17 to maintain pressure.
[0038] 4. Confirm that the equipment is securely locked and that there are no leaks in the pipeline; connect the power supply, and the temperature controller displays the set temperature and the actual temperature rise value respectively, and the two heating plates heat up simultaneously; adjust the time control instrument to select the joint heating, cooling and shutdown time period according to the process time; the equipment is in fully automatic intelligent mode.
[0039] 5. Once the heating time period is completed, the system automatically connects the water pipe solenoid valve to supply water for cooling. When the temperature drops below 60°C, the system automatically shuts off the operation, and the jointing process is complete.
[0040] 6. Press the pneumatic valve to release the pressure inside the airbag 17. The upper plate 09 with water hole will automatically return to its original position by the tension spring 19. Loosen the clamping nut 12, open the upper plate with water hole, remove the connector template 08, and check the connector condition. Turn the pneumatic valve to the drain position and repeat several times to drain the residual water in the system.
[0041] Key precautions for operation in this embodiment: First, to ensure safety during operation and prevent accidental burns or surface damage, ensure the template is placed in the center of the heating plate. Second, before pressing the pneumatic reversing valve, observe and tighten the locking nut to prevent damage to the upper plate tension spring. Third, all equipment maintenance work must be carried out by first shutting off the power, gas, and water supply to prevent unexpected situations from occurring.
