Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, and in particular to a positioning mechanism for sealing ring processing. Background Art

[0002] A plate heat exchanger is a new type of high-efficiency heat exchanger made from a series of stacked, corrugated metal sheets. Thin rectangular channels are formed between the various plates, through which heat is exchanged. Plate heat exchangers are ideal for liquid-liquid and liquid-vapor heat exchange. They feature high heat exchange efficiency, minimal heat loss, a compact and lightweight structure, a small footprint, easy installation and cleaning, a wide range of applications, and a long service life. A plate heat exchanger is constructed from a number of stamped, corrugated sheets spaced at regular intervals, sealed on all sides by sealing rings, and overlapped and compressed with a frame and compression screws. The four corner holes in the plates and sealing rings form distribution and collection pipes for the fluids, while also rationally separating the hot and cold fluids, allowing them to flow through the channels on either side of each plate, exchanging heat through the plates.

[0003] However, during the implementation of the existing technical solutions, it was found that there were at least the following technical problems:

[0004] The processing is cumbersome and the sealing ring is easily damaged: Since the existing heat exchanger sealing ring is produced by hot melting, that is, the rubber is neatly placed in the groove of the mold, and then heated at high temperature to melt the rubber into the gap of the mold, and then the mold is cooled to form the sealing ring. In this process, in order to make the rubber fill the mold perfectly, it is necessary to control the addition amount to be greater than the actual required amount of the sealing ring, which will also cause another problem, that is, waste edge. During the production process of the sealing ring, it sticks to the edge of the sealing ring. Since the sealing ring is supported by flexible materials, it cannot maintain a specific shape after being removed from the mold. Therefore, the waste edge can only be cleaned manually, and manual cleaning (mainly by dragging to remove the waste edge from the sealing ring) is not only easy to damage the sealing ring, but also requires a lot of time and energy. For this reason, we propose a positioning mechanism for sealing ring processing. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In view of the shortcomings of the existing technology, the present invention provides a positioning mechanism for sealing ring processing, which solves the technical problems that the existing heat exchanger sealing ring is cumbersome to handle and easy to damage during production.

[0007] (2) Technical solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A positioning mechanism for processing sealing rings. The positioning mechanism includes a docking part, which clamps and fixes the sealing rings formed on the mold through the docking part. A lifting rod is provided at the top of the docking part, and the lifting rod drives the docking part to move up and down, thereby adjusting the positional relationship between the docking part and the mold, facilitating the docking part to grasp the sealing rings on the mold:

[0010] The docking part corresponds to the production mold of the sealing ring up and down;

[0011] The lifting rod is installed at the top of the docking part and can drive the docking part to move up and down, providing the power for the docking plate to move up and down;

[0012] Among them, the docking part includes a docking plate, and an upper and lower corresponding extrusion part and extrusion rollers are installed inside the docking plate. The extrusion part is embedded in the top of the docking plate, and as the extrusion rollers slide, the extrusion part is driven to move up and down;

[0013] The extrusion part includes a plurality of equally spaced movable plates, and a connecting column is connected to the side of the movable plate facing the docking plate. After the connecting column penetrates the docking plate, it is correspondingly connected to the fitting strip at the bottom of the docking plate. The fitting strip and the movable plate are respectively located on the upper and lower sides of the docking plate, and the two are linked through the connecting column. The fitting strip has the same shape as the sealing ring (when adsorbing the sealing ring, it can perfectly fit with the sealing ring, improving the stability of grasping), and when the fitting strip fits with the sealing ring, the sealing ring can be adsorbed.

[0014] Preferably, an embedding groove is opened at the top of the docking plate, and the shape of the embedding groove is the same as that of the sealing ring;

[0015] Among them, the connecting column penetrates the docking plate from the position where the embedding groove is located, thereby restricting the movement direction of the fitting strip to only move up and down.

[0016] Preferably, a spring is sleeved outside the connecting column, and the spring is respectively connected to the docking plate and the movable plate;

[0017] Among them, the spring is in a compressed state. When the movable plate is not stressed, the movable plate can move upward under the action of the spring, so that the fitting strip fits with the bottom of the docking plate.

[0018] Preferably, a retaining edge is provided at the bottom of the docking plate, and the retaining edges are distributed on both sides of the fitting strip, thereby clamping the fitting strip and restricting the fitting strip between the two retaining edges;

[0019] Wherein, the width of the retaining edge is greater than the width of the fitting strip. At this time, during the upward movement of the fitting strip, it enters between the two retaining edges. Since the width of the retaining edge is greater than the width of the fitting strip, when the fitting strip is received into the gap between the retaining edges, the sealing ring connected to the connecting column follows the fitting strip and enters the gap between the two retaining edges. The waste edge outside the sealing ring is blocked by the retaining edge, thereby forming a pulling force to pull down the waste edge outside the sealing ring from the sealing ring, and the cleaning of the waste edge is completed.

[0020] Preferably, an air pipe is provided inside the connecting column, and the cavity inside the movable plate is communicated with the bottom space of the fitting strip through the air pipe;

[0021] Wherein, the cavity inside the movable plate is communicated with an air pump outside through a pipeline. Therefore, when the external air pump works, negative pressure is generated by suction at the bottom of the fitting strip. When the fitting strip is attached to the sealing ring, the sealing ring can be adsorbed, so that the fitting strip and the sealing ring are connected together;

[0022] When the fitting strip is attached to the sealing ring, the fitting strip can be adsorbed, which is convenient for driving the sealing ring to move upward together when the fitting strip moves upward subsequently.

[0023] Preferably, adjacent movable plates are connected by a connecting rope, so that when one of the movable plates moves downward, the adjacent two movable plates incline downward, which is convenient for the subsequent movement of the pressing roller.

[0024] Preferably, a driving part is provided at the top of the docking plate, and the pressing part is restricted inside the docking plate through the driving part. The pressing roller is located between the pressing part and the driving part to press the movable plate in contact with the pressing roller. Therefore, during the movement of the pressing roller, the pressing part moves downward, causing the movable plate to move towards the docking plate, so only the movement of the pressing roller needs to be controlled;

[0025] Wherein, the driving part includes a cover plate, and a driver is installed on the top of the cover plate. The pressing roller is driven to slide back and forth by the driver to provide power for the movement of the pressing roller.

[0026] Preferably, the driver includes two pulleys, and a synchronous belt is sleeved outside the two pulleys. One of the pulleys is driven by a motor installed at the bottom of the cover plate, and during the driving of the motor, the synchronous belt is driven to move;

[0027] Wherein, the synchronous belt is connected to the pressing roller and is used to drive the pressing roller to move, thereby adjusting the position of the pressing roller.

[0028] Preferably, a chute is provided at the top of the cover plate, and the chute is located between the two pulleys;

[0029] Wherein, the extending direction of the chute is consistent with the length direction of the pulley, thereby restricting the moving direction of the pressing roller.

[0030] Preferably, a rolling part is provided at the bottom of the docking plate, and the extrusion part is extruded through the rolling part;

[0031] Wherein, the rolling part includes a support frame, and the extrusion roller is installed at the bottom of the support frame. During the movement of the support frame, the extrusion roller is driven to move;

[0032] Sliders are provided outside the support frame, and the sliders are located in the sliding grooves. The sliders are connected to the synchronous belt, thereby restricting the moving direction of the support frame and preventing the support frame from moving offset.

[0033] (III) Beneficial effects

[0034] 1. Since the lifting rod is adopted to drive the docking part to lift, the positional relationship between the docking part and the mold is adjusted. Therefore, the technical problems that the existing heat exchanger sealing rings are cumbersome to process and easy to damage during production are effectively solved. Furthermore, it is realized that the sealing rings correspond to those in the mold, which not only facilitates the fixing of the sealing rings, but also facilitates the subsequent cleaning of the waste edges.

[0035] 2. Since the liftable extrusion part is adopted to adsorb the sealing ring, the technical problems that the existing heat exchanger sealing rings are cumbersome to process and easy to damage during production are effectively solved. Furthermore, the grasping and fixing of the sealing rings are realized, and at the same time, the sealing rings can be driven to lift and process.

[0036] 3. Since the rolling part is adopted to extrude the extrusion part, the technical problems that the existing heat exchanger sealing rings are cumbersome to process and easy to damage during production are effectively solved. Furthermore, the adjustment of the position of the extrusion part is realized, so that it can move towards the direction where the sealing ring is located and cooperate with the spring to control the up and down movement of the extrusion part.

[0047] In the embodiment of the present application, by providing a positioning mechanism for processing heat exchanger seals, the technical problem that the existing heat exchanger seals are cumbersome to process and easily damaged during production is effectively solved. During the production of existing heat exchanger seals, since the lifting rod is used to drive the docking part to move up and down to adjust the positional relationship between the docking part and the mold, the corresponding position with the seal in the mold is realized. This not only facilitates the fixation of the seal, but also facilitates the subsequent cleaning of the waste edge; since the liftable extrusion part is used to adsorb the seal, the grasping and fixation of the seal are realized, and at the same time, the seal can be driven to move up and down; since the roller pressing part is used to press the extrusion part, the position of the extrusion part is adjusted, enabling it to move in the direction of the seal and cooperate with the spring to control the up and down movement of the extrusion part.

[0048] Embodiment 1

[0049] The technical solution in the embodiment of the present application effectively solves the technical problem that the existing heat exchanger seals are cumbersome to process and easily damaged during production. The general idea is as follows:

[0050] In view of the problems existing in the prior art, the present invention provides a positioning mechanism for processing heat exchanger seals. The positioning mechanism includes a docking part 1, which clamps and fixes the seals formed on the mold. A lifting rod 2 is provided at the top of the docking part 1, and the lifting rod 2 drives the docking part 1 to move up and down, thereby adjusting the positional relationship between the docking part 1 and the mold, facilitating the docking part 1 to grasp the seals on the mold:

[0051] The docking part 1 corresponds to the upper and lower parts of the production mold of the sealing ring;

[0052] The lifting rod 2 is installed at the top of the docking part 1 and can drive the docking part 1 to move up and down, providing the power for the up and down movement of the docking plate 11;

[0053] Among them, the docking part 1 includes a docking plate 11, and the inside of the docking plate 11 is provided with corresponding upper and lower extrusion parts 14 and extrusion rollers 152. The extrusion part 14 is embedded in the top of the docking plate 11. As the extrusion roller 152 slides, it drives the extrusion part 14 to move up and down;

[0054] The extrusion part 14 includes a plurality of equally spaced movable plates 141, and a connecting column 142 is connected to the side of the movable plate 141 facing the docking plate 11. As Figure 5 shown, after the connecting column 142 penetrates the docking plate 11, it is correspondingly connected to the fitting strip 143 at the bottom of the docking plate 11. As Figure 6 and Figure 7 shown, the fitting strip 143 and the movable plate 141 are respectively located on the upper and lower sides of the docking plate 11, and the two are linked through the connecting column 142. The fitting strip 143 has the same shape as the sealing ring (when adsorbing the sealing ring, it can perfectly fit with the sealing ring, improving the stability of grasping), and can adsorb the sealing ring when the fitting strip 143 is attached to the sealing ring.

[0055] In some examples, an embedding groove 13 is formed at the top of the docking plate 11, and the shape of the embedding groove 13 is the same as that of the sealing ring. As Figure 2 shown;

[0056] Among them, the connecting column 142 penetrates the docking plate 11 from the position where the embedding groove 13 is located, thereby restricting the movement direction of the fitting strip 143 to only move up and down.

[0057] In some examples, a spring is sleeved outside the connecting column 142, and the spring is respectively connected to the docking plate 11 and the movable plate 141;

[0058] Among them, the spring is in a compressed state. When the movable plate 141 is not stressed, the movable plate 141 can move upward under the action of the spring, so that the fitting strip 143 is attached to the bottom of the docking plate 11.

[0059] In some examples, a baffle 16 is provided at the bottom of the docking plate 11, and the baffle 16 is distributed on both sides of the fitting strip 143. As Figure 7 shown, the fitting strip 143 is clamped, so that the fitting strip 143 is restricted between the two baffles 16;

[0060] Among them, the width of the flange 16 is greater than the width of the fitting strip 143. At this time, during the upward movement of the fitting strip 143, it enters between the two flanges 16. Since the width of the flange 16 is greater than the width of the fitting strip 143, when the fitting strip 143 is received into the gap between the two flanges 16, the sealing ring connected to the connecting column 142 follows the fitting strip 143 and enters the gap between the two flanges 16. The waste edge outside the sealing ring is blocked by the flange 16, thereby forming a pulling force to pull down the waste edge outside the sealing ring from the sealing ring, and the cleaning of the waste edge is completed.

[0061] In some examples, an air pipe is provided inside the connecting column 142, and the cavity inside the movable plate 141 is communicated with the bottom space of the fitting strip 143 through the air pipe;

[0062] Among them, the cavity inside the movable plate 141 is communicated with an air pump outside through a pipeline. Therefore, when the external air pump works, negative pressure is generated by suction at the bottom of the fitting strip 143. When the fitting strip 143 is attached to the sealing ring, the sealing ring can be adsorbed, so that the fitting strip 143 and the sealing ring are connected together;

[0063] When the fitting strip 143 is attached to the sealing ring, the fitting strip 143 can be adsorbed, which is convenient for driving the sealing ring to move upward together when the fitting strip 143 moves upward later.

[0064] In some examples, adjacent movable plates 141 are connected by a connecting rope, so that when one of the movable plates 141 moves downward, the adjacent two movable plates 141 tilt downward, which is convenient for the subsequent movement of the pressing roller 152.

[0065] In the specific implementation process, an external air pump is turned on. When the external air pump is working, negative pressure is generated by sucking air at the bottom of the fitting strip 143. Then, the pressing roller 152 is controlled to roll on the top of the movable plate 141. During the rolling process, the movable plate 141 is pressed downward, so that the connecting column 142 located below the movable plate 141 drives the fitting strip 143 to move downward together. At this time, the fitting strip 143 extends out of the edge 16 and fits with the outer wall of the sealing ring. Since negative pressure is generated at the bottom of the fitting strip 143 by the air pump, when the fitting strip 143 fits with the sealing ring, the sealing ring can be adsorbed, so that the fitting strip 143 is connected to the sealing ring. After the pressing roller 152 rolls over, the movable plate 141 is pushed up by the spring outside the connecting column 142, even if the sealing ring moves in the direction of the docking plate 11. Since the width of the edge 16 is greater than the width of the fitting strip 143, when the fitting strip 143 is received in the gap between the edges 16, the sealing ring connected to the connecting column 142 follows the fitting strip 143 and enters the gap between the two edges 16 together. The waste edge outside the sealing ring is blocked by the edge 16, thus forming a pulling force to pull down the waste edge outside the sealing ring from the sealing ring, and the cleaning of the waste edge is completed.

[0066] Embodiment 2

[0067] Based on Embodiment 1, the embodiment of the present application provides a feasible technical solution for the movement of the pressing roller. The general idea is as follows:

[0068] A driving part 12 is provided at the top of the docking plate 11, and the pressing part 14 is restricted inside the docking plate 11 through the driving part 12. The pressing roller 152 is located between the pressing part 14 and the driving part 12, and presses the movable plate 141 that fits with the pressing roller 152. Therefore, during the movement of the pressing roller 152, the pressing part 14 moves downward, so that the movable plate 141 moves toward the docking plate 11. Therefore, only the movement of the pressing roller 152 needs to be controlled.

[0069] Among them, the driving part 12 includes a cover plate 121, and a driver is installed at the top of the cover plate 121. The pressing roller 152 is driven to slide back and forth by the driver, providing power for the movement of the pressing roller 152.

[0070] In some examples, the driver includes two pulleys 122, and a synchronous belt 123 is sleeved outside the two pulleys 122. One of the pulleys 122 is driven by a motor installed at the bottom of the cover plate 121. During the driving process of the motor, the synchronous belt 123 is driven to move.

[0071] Among them, the synchronous belt 123 is connected to the pressing roller 152 and is used to drive the pressing roller 152 to move, thereby adjusting the position of the pressing roller 152.

[0072] In some examples, a chute is provided at the top of the cover plate 121, and the chute is located between the two pulleys 122, as Figure 3 shown;

[0073] wherein, the extending direction of the chute is consistent with the length direction of the pulley 122, thereby restricting the moving direction of the pressing roller 152.

[0074] Embodiment 3

[0075] Based on Embodiment 1, the embodiment of the present application provides power for the movement of the pressing roller, and the general idea is as follows:

[0076] A roller pressing part 15 is provided at the bottom of the docking plate 11, and the pressing part 14 is pressed through the roller pressing part 15;

[0077] wherein, the roller pressing part 15 includes a support frame 151, and the pressing roller 152 is installed at the bottom of the support frame 151. During the movement of the support frame 151, the pressing roller 152 is driven to move;

[0078] A slider 153 is provided outside the support frame 151, and the slider 153 is located in the chute. The slider 153 is connected to the synchronous belt 123, thereby restricting the moving direction of the support frame 151 and preventing the support frame 151 from moving offset.

[0079] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
