Description

Technical Field

[0001] This utility model relates to the field of waterstop processing technology, and in particular to an energy-saving hot air circulation system for a continuous vulcanization production line of waterstops. Background Technology

[0002] The energy-saving hot air circulation system of the continuous vulcanization production line for waterstops is a core heat energy supply and circulation subsystem specifically designed for the continuous vulcanization production process of waterstops. Its core feature is that, based on meeting the stable and uniform heat source required for waterstop vulcanization, it significantly reduces energy consumption and improves energy utilization efficiency through technologies such as optimized heat flow organization, waste heat recovery, and intelligent temperature control. At the same time, it is a specialized equipment system that ensures the quality of waterstop vulcanization. During the processing of waterstops, the surface is prone to expansion and bulging, which affects the subsequent vulcanization process.

[0003] Referring to prior art document 202421730502.5, a box-type hot air circulation system is provided. This utility model has a guide plate assembly with adjustable size of each guide air vent on the input side of the heating area. The wind speed and air volume of hot air blown to each point in the heating area can be adjusted according to actual needs to improve the uniformity of workpiece heating temperature. By setting a fixed guide plate in the second side air duct on the output side of the heating area to guide the cold air output from the heating area to be evenly dispersed and blown towards the heating device, it is further ensured that the equipment can achieve the optimal hot air circulation state.

[0004] The device provided in the above document cannot press the surface of the heated workpiece. Considering that the material of the workpiece may deform due to high temperature and form an expanded protruding structure on the surface, if it is not dealt with in time, it may affect the next process and reduce the quality of the product. At the same time, the hot air in the hot circulation device is not screened or filtered, and there is no need to disassemble the pipes, which is convenient. Utility Model Content

[0005] The purpose of this invention is to solve the problem of surface expansion and protrusion of waterstops before vulcanization in existing technologies, and to propose an energy-saving hot air circulation system for continuous vulcanization production lines of waterstops.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The energy-saving hot air circulation system of the continuous vulcanization production line for waterstops includes a pressing table for placing the waterstops, a heating box body with a discharge port and a vulcanization box body with a discharge port and a discharge port. The heating box body has a heating chamber, and the vulcanization box body has a vulcanization chamber. The heating box body is equipped with a pressing plate for pressing the protrusions on the surface of the waterstops through a pressing assembly. A connecting pipe for circulating heat source is fixedly connected between the vulcanization box body and the vulcanization chamber.

[0008] Preferably, the pressing platform is placed horizontally, the inlet and outlet are located on both sides of the heating box body and the vulcanizing box body, the heating chamber, the vulcanizing chamber and the inner wall of the connecting pipe are fixedly installed with heat insulation cotton, and the surface of the heating box body, the vulcanizing box body and the connecting pipe is fixedly installed with heat insulation cotton.

[0009] Preferably, a temperature sensor for monitoring temperature is fixedly installed inside the heating chamber and the vulcanizing chamber, and a ventilation plate is fixedly installed inside the heating chamber and the vulcanizing chamber, with the temperature sensor located above the ventilation plate.

[0010] Preferably, the pressing assembly includes a guide frame fixedly mounted on the heating box body, and a sliding groove is provided in the guide frame. A driving cylinder is fixedly mounted on the heating box body. A slider connected to the output end of the driving cylinder is slidably sleeved on the sliding groove. An adjusting frame is fixedly connected to the guide frame. The adjusting frame has symmetrical mounting holes, and a rotating shaft is fixedly mounted in the mounting holes. Symmetrically arranged traction plates are pinned on the adjusting frame. A movable plate is pinned on the rotating shaft, and a connecting frame is connected between the movable plate and the connecting frame. The pressing plate is disposed on the connecting frame.

[0011] The adjustment frame has movable holes corresponding to the slider, and the two ends of the movable plate are respectively connected to the rotating shaft and the connecting frame pin.

[0012] Preferably, the guide frame is vertically arranged, the slider extends to the outer side of the guide frame, the adjustment frame is horizontally arranged, and the adjustment frame has a U-shaped structure, with the slider extending to the outer side of the adjustment frame.

[0013] Preferably, the connecting pipe has a U-shaped structure, and a sieve plate for screening out particulate matter is slidably sleeved inside the connecting pipe. The sieve plate has uniformly arranged sieve holes. The vulcanizing box body has a connecting hole, and the lower end of the connecting pipe extends into the connecting hole. The vulcanizing box body has a chip removal port corresponding to the sieve plate.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. In this utility model, the sliding block is pushed along the vertical guide frame by the driving cylinder. Through the transmission of the movable plate and the connecting frame, the pressing plate generates a pressing force perpendicular to the waterstop, which effectively flattens the protrusions and bulges formed on the surface of the waterstop after preheating during production. This avoids the protruding parts of the waterstop affecting the effect of subsequent vulcanization treatment and improves the production quality of the waterstop to a certain extent.

[0016] 2. In this utility model, the connecting pipe 6 is designed with a U-shaped structure. High-temperature hot air enters the connecting pipe 6 from the upper part of the vulcanizing chamber, flows down the connecting pipe 6 to the lower part of the vulcanizing chamber, and then re-enters the vulcanizing chamber to participate in the circulation, forming an upper and lower closed loop. The U-shaped structure prolongs the residence time of the hot air in the pipe. By filtering the tiny debris and raw material residue particles generated during the vulcanization process in the hot air circulation through the sieve plate that is slidably sleeved in the connecting pipe, it avoids impurities adhering to the surface of the waterstop and forming defects such as indentations and spots. At the same time, the chip removal port on the vulcanizing box body makes it convenient to periodically remove the sieve plate to clean impurities without disassembling the pipe, which is convenient.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5The energy-saving hot air circulation system of the continuous vulcanization production line for waterstop includes a pressing table 1 for placing the waterstop, a heating box body 2 with a discharge port and a feed port, and a vulcanization box body 3. To further explain, a controller that is electrically connected to a drive cylinder 41 and a temperature sensor 8 is fixedly installed on the pressing table 1.

[0026] The heating chamber 2 has a heating chamber inside, and the vulcanizing chamber 3 has a vulcanizing chamber inside. Since the preheating and vulcanizing processes of the waterstop are at different temperatures, the entire device is divided into the heating chamber 2 and the vulcanizing chamber 3.

[0027] The heating box body 2 is used to preheat the waterstop, and the vulcanizing box body 3 is used to complete the vulcanization molding of the waterstop. The inlet and outlet of the heating box body 2 and the vulcanizing box body 3 form a continuous production channel. The waterstop can enter the equipment from the inlet, and after being heated and vulcanized in sequence, it is output from the outlet, realizing assembly line operation.

[0028] The heating box body 2 is equipped with a pressing plate 49 for pressing the protrusions on the surface of the waterstop through the pressing component 4. The vulcanizing box body 3 and the vulcanizing chamber are fixedly connected by a connecting pipe 6 for circulating heat source up and down.

[0029] The pressing platform 1 is placed horizontally. The horizontal design of the pressing platform 1 provides a reference surface for the vertical pressing of the pressing plate 49, ensuring that the pressing force is applied evenly to the surface of the waterstop and improving the flatness.

[0030] The inlet and outlet are located on both sides of the heating chamber body 2 and the vulcanizing chamber body 3. Insulation cotton is fixedly installed on the inner wall of the heating chamber, the vulcanizing chamber and the connecting pipe 6. Insulation cotton is fixedly installed on the surface of the heating chamber body 2, the vulcanizing chamber body 3 and the connecting pipe 6. By installing insulation cotton on the inner wall of the heating chamber, the vulcanizing chamber and the connecting pipe 6, the heat source inside the chamber is directly isolated from the low-temperature environment outside, reducing the loss of heat inside the chamber through the wall conduction.

[0031] By installing insulation cotton on the surfaces of the heating box body 2, the vulcanizing box body 3 and the connecting pipe 6, a secondary insulation barrier is formed, which further reduces heat loss, reduces the frequency of heat source replenishment, reduces energy consumption, and ensures the stable temperature environment required for the vulcanization process.

[0032] Temperature sensors 8 for monitoring temperature are fixedly installed in the heating chamber and vulcanizing chamber. Ventilation plates 9 are fixedly installed in the heating chamber and vulcanizing chamber. Temperature sensors 8 are located above ventilation plates 9. Temperature sensors 8 collect hot air temperature data in the chamber in real time and transmit the data to the control system.

[0033] When the temperature is lower than the process set value, the control system automatically increases the heat source supply; when the temperature is higher than the set value, it reduces the heat source supply to avoid the waterstop aging due to excessively high temperature and insufficient vulcanization due to excessively low temperature. At the same time, precise temperature control reduces the consumption of ineffective heat sources, thereby achieving the goal of reducing energy consumption.

[0034] The ventilation plate 9 is made of stainless steel with uniform openings to avoid high-temperature corrosion. The hot air output by the ventilation plate 9 is dispersed into a uniform airflow to ensure that each area in the cavity is heated evenly, solving the problems of insufficient edge vulcanization and center aging caused by concentrated hot air in traditional equipment.

[0035] By placing the temperature sensor 8 above the ventilation plate 9, the temperature above the ventilation plate 9 can better represent the actual temperature of the hot air acting on the waterstop inside the cavity, thus ensuring the accuracy of temperature monitoring.

[0036] The pressing assembly 4 includes a guide frame 42 fixedly installed on the heating box body 2, and a sliding groove is provided in the guide frame 42. A drive cylinder 41 is fixedly installed on the heating box body 2 to avoid high temperature affecting the life of the cylinder 41.

[0037] The groove restricts the slider 43 to move only in the vertical direction, preventing the slider 43 from deviating and causing the pressing plate 49 to tilt. At the same time, the vertical layout ensures that the pressing direction of the pressing plate 49 is perpendicular to the surface of the waterstop, ensuring that the pressing force is applied evenly to the waterstop and avoiding local pressing that is too light or too heavy.

[0038] A slider 43 connected to the output end of the drive cylinder 41 is slidably sleeved on the slide groove. An adjustment frame 44 is fixedly connected to the guide frame 42. The adjustment frame 44 has symmetrical mounting holes, and a rotating shaft is fixedly installed in the mounting holes. A symmetrically arranged traction plate 47 is mounted on the adjustment frame 44 with a pin. A movable plate 46 is mounted on the rotating shaft with a pin. A connecting frame 48 is connected between the movable plate 46 and 17. A pressing plate 49 is provided on the connecting frame 48.

[0039] The adjustment frame 44 ensures that the transmission components such as the movable plate 46 and the connecting frame 48 move in the same horizontal plane, driving the pressing plate 49 to press stably in the horizontal direction, and preventing the pressing plate 49 from shifting up and down.

[0040] The adjustment frame 44 has a movable hole corresponding to the slider 43 to ensure the continuity of the pressing action.

[0041] The two ends of the movable plate 46 are respectively connected to the pivot and the connecting frame 48 pin. The guide frame 42 is set vertically, the slider 43 extends to the outside of the guide frame 42, the adjustment frame 44 is set horizontally, and the adjustment frame 44 has a U-shaped structure, with the slider 43 extending to the outside of the adjustment frame 44.

[0042] The slider 43 and the movable hole of the adjustment bracket 44 are precisely matched to ensure that the driving force of the slider 43 to the movable plate 46 is accurately transmitted, thereby improving the stability of the pressing action.

[0043] By pressing the raised parts of the waterstop surface vertically with the pressing plate 49, the subsequent vulcanization treatment of the waterstop is more complete, thus improving the product quality.

[0044] The connecting pipe 6 has a U-shaped structure. The high-temperature hot air enters the connecting pipe 6 from the upper part of the vulcanizing chamber, flows down the connecting pipe 6 to the lower part of the vulcanizing chamber, and then re-enters the vulcanizing chamber to participate in the circulation, forming a closed loop. The U-shaped structure prolongs the residence time of the hot air in the connecting pipe (6), reduces heat loss, and ensures that the temperature inside the vulcanizing chamber is uniform.

[0045] A sieve plate 5 for screening out particulate matter is slidably sleeved inside the connecting pipe 6, and the sieve plate 5 has uniformly arranged sieve holes. The sieve plate 5 is a metal filter plate. The uniformly arranged sieve holes of the sieve plate 5 screen out impurities carried in the hot air circulation, such as tiny debris and raw material residue particles generated during the vulcanization process of the waterstop.

[0046] If impurities enter the heating chamber or vulcanization chamber, they may adhere to the surface of the waterstop and form defects, or block the hot air outlet and affect circulation efficiency. The sieve plate 5 effectively avoids similar problems and improves the qualification rate of the finished waterstop.

[0047] A connection hole is provided on the vulcanizing box body 3, and the lower end of the connecting pipe 6 extends into the connection hole. A chip collection port 7 corresponding to the sieve plate 5 is provided on the vulcanizing box body 3.

[0048] The connecting hole on the vulcanizing box body 3 matches the lower end of the connecting pipe 6 to ensure that the connecting pipe 6 is sealed to the vulcanizing chamber. The chip removal port 7 corresponds to the position of the sieve plate 5 and is equipped with an openable sealing cover.

[0049] When a large amount of impurities accumulate on the screen plate 5, the screen plate 5 can be pulled out from the chip removal port 7 for cleaning by opening the sealing cover. There is no need to disassemble the connecting pipe 6, which improves equipment operation and maintenance and is convenient.

[0050] The functional principle of this utility model can be explained through the following operation methods:

[0051] When in use, the operator puts the waterstop into the heating chamber body 2 through the feed port. The waterstop is heated evenly by hot air to the temperature required for vulcanization. The temperature sensor 8 in the heating chamber monitors the temperature in the heating chamber in real time to prevent the temperature from being too high.

[0052] The operator removes the heated waterstop from the discharge port;

[0053] The waterstop was then placed on the pressing table 1;

[0054] The controller sends a start signal to the drive cylinder 41, the output end of the drive cylinder 41 moves downward, and drives the slider 43 to move downward in the guide hole. The connecting frame 48 moves downward synchronously under the restriction of the two movable plates 46, and drives the pressing plate 49 to move downward synchronously.

[0055] When the pressing plate 49 comes into contact with the upper surface of the waterstop, it presses down the expansion protrusion on the surface of the waterstop to facilitate the subsequent vulcanization process.

[0056] As time goes on, more particles continue to adhere to the screen plate 5. The screen plate 5 is then manually removed from the chip removal port 7, cleaned, and put back into the connecting pipe 6.

[0057] The pressed waterstop is put into the inlet of the vulcanizing box body 3 and vulcanized in a heated environment. The vulcanized waterstop is then taken out from the outlet of the vulcanizing box body 3 and awaits the processing of the next batch of waterstops.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
