Description

Technical Field

[0001] The invention relates to the technical field of cooling and shaping, and more specifically to a cooling and shaping device for a rubber sealing strip. Background Art

[0002] Rubber sealing strips are strip-shaped rubber products used to fill gaps in structures to seal. They are widely used in construction, automobiles, doors and windows, ships, machinery and other fields. The production process of rubber sealing strips usually includes the following main steps: mixing, calendering, extrusion, vulcanization, cutting and testing of rubber raw materials. In the extrusion section, the mixed rubber material is extruded into the desired shape through a die in an extruder. In this process, the rubber material is extruded under high temperature and pressure to form a continuous sealing strip. The extruded sealing strip needs to be cooled and shaped to avoid deformation of the sealing strip during the subsequent vulcanization process.

[0003] The U-shaped rubber strip is a type of rubber sealing strip with a U-shaped cross section. With its unique U-shaped design, it provides good sealing, decorative, anti-collision and protection functions. At present, the cooling and shaping of the U-shaped rubber strip is generally done by passing the extruded U-shaped rubber strip into a cooling water tank, and cooling the U-shaped rubber tube through circulating cold water to solidify it and maintain the required shape and size to achieve cooling and shaping.

[0004] However, this cooling method still has certain defects: first, when the prior art cools down the rubber strip by using cold water in the cooling water tank, since the U-shaped rubber strip needs a certain amount of time to fully solidify and maintain the desired shape and size, the feeding speed of the U-shaped rubber strip is relatively slow, and the extrusion efficiency of the extruder is faster than the cooling speed of the U-shaped rubber strip. Therefore, in order to match the cooling speed of the U-shaped rubber strip, the extrusion speed of the extruder is often slightly slowed down, so that the working performance of the extruder cannot be fully released. In the long production process, not only the cooling and shaping efficiency will be affected, but also the working efficiency of the extruder will be affected, so that the production efficiency of the U-shaped rubber strip is reduced. Summary of the invention

[0005] The invention provides a rubber sealing strip cooling and shaping device, which solves the technical problems in the prior art that in order to match the cooling speed of a U-shaped rubber strip, the extrusion speed of an extruder is slowed down and the continuous circulation of cold water produces polluted water.

[0006] The present invention provides a rubber sealing strip cooling and shaping device, comprising a cooling water trough for cooling a U-shaped rubber strip, wherein an air jet shaping unit and an anti-deformation feeding unit are arranged in the cooling water trough, wherein the air jet shaping unit comprises a shaping component and an air jet component for jetting air into the shaping component, and wherein the anti-deformation feeding unit comprises a feeding component and a driving component for driving the feeding component.

[0007] The shaping component includes a plurality of shaping tubes fixedly mounted on the inner wall at the bottom of the cooling water tank and evenly spaced, a plurality of evenly arranged jet hoods fixedly mounted on both the front and rear sides of the shaping tubes, a plurality of circumferentially distributed jet holes opened on the outer side of the jet hoods, a plurality of rolling steel balls evenly spaced and rotatably mounted on the top of the shaping tubes to facilitate the conveying of the U-shaped rubber strips, and the feeding component includes two rotating shafts rotatably mounted between the front and rear inner walls of the cooling water tank and symmetrically disposed on the left and right, and a driving belt is connected to the outer sides of the two rotating shafts through a transmission roller for common transmission.

[0008] A number of U-shaped rubber strips corresponding to the number of shaping tubes are covered on the surface of the shaping tubes. The cold water in the cooling water tank preliminarily cools the U-shaped rubber strips. At the same time, the top of the U-shaped rubber strips abuts against the driving belt. The rotating shaft rotates to drive the driving belt to drive the U-shaped rubber strips to be transported to the right. During the transportation process, the jet assembly sends cold air into the shaping tube. The cold air is sprayed onto the U-shaped rubber strips through the jet hood and the jet hole for further cooling, and at the same time cools the water that has absorbed heat and heated up.

[0009] Furthermore, the jet assembly includes an air pump fixedly installed on the left side of the cooling water tank and an air inlet pipe and an air outlet pipe fixedly installed on the rear side of the air pump. A connecting pipe is fixedly installed on the top of the air outlet pipe, and several diversion pipes corresponding to the shaping pipe are fixedly installed on the top of the connecting pipe. The several diversion pipes are respectively fixedly connected to the corresponding diversion pipes.

[0010] Furthermore, the feeding assembly also includes two rotating shafts 2 rotatably installed between the front and rear inner walls of the cooling water trough and a driving roller fixedly sleeved on the outside of the rotating shafts 2. The two rotating shafts 2 are symmetrically distributed on the left and right sides of the driving belt, and two mounting plates 1 symmetrically installed front and back are fixedly installed on the right end of the cooling water trough.

[0011] Furthermore, two rotating shafts three symmetrically arranged in an upward and downward manner are rotatably arranged between the two mounting plates one, and feed rollers are fixedly sleeved on the outer sides of the two rotating shafts three, and the two feed rollers cooperate with each other to transport the U-shaped rubber strip.

[0012] Furthermore, two mounting plates 2 are fixedly installed at the left end of the cooling water trough in a front-to-back symmetrical manner, a supporting roller for supporting the U-shaped rubber strip is rotatably installed between the two mounting plates 2, and movable overlapping rollers are rotatably installed between the two mounting plates 1 and between the two mounting plates 2, and the movable overlapping rollers overlap the top of the U-shaped rubber strip.

[0013] Furthermore, the driving assembly includes a driving motor fixedly mounted on the front side of the cooling water trough, the front end of the left rotating shaft 1 passes through the cooling water trough and is fixedly connected to the output shaft of the driving motor, and the rear ends of the two rotating shafts 1 and the two rotating shafts 2 all pass through the cooling water trough.

[0014] Furthermore, a driving pulley 1 is fixedly sleeved on the rear ends of the two rotating shafts 1, and a driven pulley 1 is fixedly sleeved on the outer sides of the two rotating shafts 2. The driving pulley 1 and the corresponding driven pulley 1 are jointly connected by a belt 1.

[0015] Furthermore, a driving pulley 2 is fixedly sleeved on the rear end of the right rotating shaft 2, and a driven pulley 2 is fixedly sleeved on the rear end of the upper rotating shaft 3 through the rear mounting plate 1, and a belt 2 is commonly connected to the driving pulley 2 and the driven pulley 2.

[0016] Furthermore, the front ends of the two rotating shafts 3 pass through the front mounting plate 1, and the front end fixing sleeve of the upper rotating shaft 3 is provided with a driving gear, and the front end fixing sleeve of the lower rotating shaft 3 is provided with a driven gear meshing with the driving gear.

[0017] Furthermore, a left-right symmetrical water inlet pipe and a drain pipe are fixedly installed on the front side of the cooling water trough, and the anti-deformation feeding unit also includes a plurality of rotating rods rotatably installed between the front and rear inner walls of the cooling water trough and abutting against the driving belt.

[0018] The beneficial effects of the present invention are: 1. The wall of the shaping tube is cooled by cold air. When the U-shaped rubber strip is covered and attached to the surface of the shaping tube, the temperature of the surface of the shaping tube will be transferred to the U-shaped rubber strip after the preliminary shaping, thereby further cooling and shaping the U-shaped rubber strip. At the same time, since the contour of the shaping tube coincides with the inner side of the U-shaped rubber strip, deformation of the U-shaped rubber strip due to shape instability during the cooling process is avoided, and the cold air sprayed through the jet hood and the jet hole directly acts on the surface of the U-shaped rubber strip to enhance the cooling effect, and through the wrapping effect of the U-shaped rubber strip, it is ensured that the cold air fully contacts and cools the U-shaped rubber strip, thereby achieving further jet cooling of the U-shaped rubber strip, thereby greatly improving the cooling and shaping efficiency and effect of the U-shaped rubber strip. Furthermore, due to the improvement of the cooling and shaping efficiency, the feeding speed of the U-shaped rubber strip can be correspondingly accelerated, thereby matching the extrusion speed of the extruder, thereby avoiding the problem of reduced working efficiency of the extruder due to waiting for cooling, thereby improving the production efficiency of the U-shaped rubber strip.

DETAILED DESCRIPTION

[0028] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0029] See also Figure 1 , Figure 4 and Figure 5In this embodiment, a rubber sealing strip cooling and shaping device is proposed, including a cooling water trough 1 for cooling a U-shaped rubber strip 2, wherein an air jet shaping unit 5 and an anti-deformation feeding unit 6 are arranged in the cooling water trough 1, wherein the air jet shaping unit 5 includes a shaping component 501 and an air jet component 502 for jetting air into the shaping component 501, and the anti-deformation feeding unit 6 includes a feeding component 601 and a driving component 602 for driving the feeding component 601.

[0030] See also Figure 1 The feeding assembly 601 includes two rotating shafts 6011 rotatably mounted between the front and rear inner walls of the cooling water tank 1 and symmetrically on the left and right. The outer sides of the two rotating shafts 6011 are jointly connected with a driving belt 6012 through a driving roller. A water inlet pipe 3 and a drain pipe 4 are fixedly mounted on the front side of the cooling water tank 1, and the water inlet pipe 3 and the drain pipe 4 are symmetrically arranged on the left and right. A plurality of evenly arranged through holes (not shown in the figure) are opened on the surface of the driving belt 6012, so that when the driving belt 6012 is running, it can more effectively dissipate the heat on the surface and inside of the U-shaped rubber strip 2 in contact with it. In particular, when the U-shaped rubber strip 2 is further cooled and shaped by the jet assembly 502, the through holes can serve as an additional heat dissipation channel to help accelerate the transfer and loss of heat and improve the cooling efficiency. In addition, the through holes can make it easier for cold water to penetrate the driving belt 6012 and directly act on the surface of the U-shaped rubber strip 2. This penetrability not only improves the cooling efficiency, but also makes the fluid distribution more even, avoiding local overcooling or local overheating in the water.

[0031] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 The feeding assembly 601 also includes two rotating shafts 6013 rotatably installed between the front and rear inner walls of the cooling water trough 1 and a driving roller 6014 fixedly sleeved on the outside of the rotating shafts 6013. The two rotating shafts 6013 are symmetrically distributed on the left and right sides of the driving belt 6012. Two front-to-back symmetrical mounting plates 6015 are fixedly installed on the right end of the cooling water trough 1. The anti-deformation feeding unit 6 also includes a plurality of rotating rods 603 rotatably installed between the front and rear inner walls of the cooling water trough 1 and abutting against the driving belt 6012.

[0032] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 Two rotating shafts 6016 symmetrically arranged in an upward and downward direction are rotatably installed between the two mounting plates 1 6015 . Feeding rollers 6017 are fixedly sleeved on the outer sides of the two rotating shafts 6016 . The two feeding rollers 6017 cooperate with each other to transport the U-shaped rubber strip 2 .

[0033] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 Two front-to-back symmetrical mounting plates 6018 are fixedly installed at the left end of the cooling water tank 1, and a supporting roller 6019 for supporting the U-shaped rubber strip 2 is rotatably installed between the two mounting plates 6018. Movable overlapping rollers 6010 are rotatably installed between the two mounting plates 1 6015 and between the two mounting plates 2 6018, and the movable overlapping rollers 6010 overlap the top of the U-shaped rubber strip 2.

[0034] See also Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 The driving assembly 602 includes a driving motor 6021 fixedly installed on the front side of the cooling water tank 1. The front end of the rotating shaft 1 6011 on the left side passes through the cooling water tank 1 and is fixedly connected to the output shaft of the driving motor 6021. The rear ends of the two rotating shafts 1 6011 and the two rotating shafts 2 6013 all pass through the cooling water tank 1.

[0035] See also Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 The rear ends of the two rotating shafts 6011 are fixedly sleeved with a driving pulley 6022, and the outer sides of the two rotating shafts 6013 are fixedly sleeved with a driven pulley 6023. The driving pulley 6022 and the corresponding driven pulley 6023 are jointly connected with a belt 6024.

[0036] See also Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 The rear end of the right rotating shaft 6013 is also fixedly provided with a driving pulley 6025, and the rear end of the upper rotating shaft 6016 passes through the rear mounting plate 6015 and is fixedly provided with a driven pulley 6026. The driving pulley 6025 and the driven pulley 6026 are jointly connected with a belt 6027 for transmission.

[0037] See also Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 The front ends of the two rotating shafts 6016 both penetrate the front mounting plate 1 6015, and the front end fixing sleeve of the upper rotating shaft 3 6016 is provided with a driving gear 6028, and the front end fixing sleeve of the lower rotating shaft 3 6016 is provided with a driven gear 6029 meshing with the driving gear 6028.

[0038] When in use, the U-shaped rubber strip 2 is passed from left to right in sequence through the upper side of the supporting roller 6019, the lower side of the left movable overlapping roller 6010, the lower side of the left driving roller 6014, the lower side of the driving belt 6012, the lower side of the right driving roller 6014 and the lower side of the right movable overlapping roller 6010, and then passes through between the two feeding rollers 6017. At this time, the movable overlapping roller 6010 overlaps the upper side of the U-shaped rubber strip 2 to prevent the U-shaped rubber strip 2 from floating under the buoyancy of water, and at this time, the U-shaped rubber strip 2 is covered and attached to the shaping component 501. Then, the driving motor 6021 is started, and the output shaft of the driving motor 6021 rotates to drive the left driving roller through friction. The driving belt 6012 moves, and the movement of the driving belt 6012 is transmitted to the right transmission roller through friction, causing it to start rotating as well. In this process, the rotation speeds of the two transmission rollers will tend to be consistent, so that the two rotating shafts 6011 rotate synchronously, so that the rotation of the rotating shaft 6011 drives the two driving pulleys 6022 to rotate, and the rotation of the driving pulley 6022 drives the driven pulley 6023 to rotate through the belt 6024, thereby driving the two rotating shafts 6013 to rotate, and then driving the two driving rollers 6014 to rotate, so that the left driving roller 6014 transports the U-shaped rubber strip 2 that has entered the water tank and been preliminarily shaped in cold water to the shaping component 501.

[0039] At the same time, during the operation of the driving belt 6012, the U-shaped rubber strip 2 covering the shaping component 501 is transported to the right through friction. During this process, the U-shaped rubber strip 2 is further cooled and shaped with the cooperation of the jet component 502 and the shaping component 501. At the same time, the cold water in the cooling water tank 1 gradually heats up after absorbing the heat of the U-shaped rubber strip 2, and the cold air sprayed by the jet component 502 further cools and shapes the U-shaped rubber strip 2 while also cooling down the heated water.

[0040] After further cooling and shaping, the U-shaped rubber strip 2 is driven to the upper right by the driving roller 6014. At the same time, when the right rotating shaft 2 6013 rotates, it will also drive the driving pulley 2 6025 to rotate. The driving pulley 2 6025 rotates through the belt 2 6027 to drive the upper rotating shaft 3 6016 to rotate. The upper rotating shaft 3 6016 rotates to drive the driving gear 6028 to engage with the driven gear 6029, thereby driving the lower rotating shaft 3 6016 to rotate, and then the two feeding rollers 6017 rotate relative to each other, and the U-shaped rubber strip 2 after shaping is transported to the right for discharge.

[0041] See also Figure 1 , Figure 4 and Figure 7The shaping component 501 includes a plurality of shaping tubes 5011 fixedly installed on the inner wall of the bottom of the cooling water tank 1 and evenly spaced, a plurality of evenly arranged jet hoods 5012 are fixedly installed on both the front and rear sides of the shaping tube 5011, a plurality of circumferentially distributed jet holes 5013 are opened on the outer side of the jet hood 5012, a plurality of rolling steel balls 5014 evenly spaced are rotatably installed on the top of the shaping tube 5011 to facilitate the transportation of the U-shaped rubber strip 2, and the shaping tube 5011 is made of aluminum alloy.

[0042] See also Figure 4 and Figure 7 The jet assembly 502 includes an air pump 5023 fixedly installed on the left side of the cooling water tank 1, and an air inlet pipe 5025 and an air outlet pipe 5024 fixedly installed on the rear side of the air pump 5023. A connecting pipe 5022 is fixedly installed on the top of the air outlet pipe 5024. A plurality of branch pipes 5021 corresponding to the shaping pipe 5011 are fixedly installed on the top of the connecting pipe 5022. The plurality of branch pipes 5021 are fixedly connected to the corresponding branch pipes 5021 respectively.

[0043] When in use, the air inlet pipe 5025 is first connected to the external cold air source. When the U-shaped rubber strip 2 enters the cooling water tank 1 for preliminary water cooling and shaping, the air pump 5023 is started, so that the air inlet pipe 5025 pumps the cold air into the air outlet pipe 5024, and then passes through the connecting pipe 5022 and a plurality of shunt pipes 5021 into the corresponding shaping tube 5011 in sequence to cool the tube wall of the shaping tube 5011. At the same time, the cold air is ejected through the jet hood 5012 and the jet hole 5013. When the U-shaped rubber strip 2 covers the surface of the shaping tube 5011, the temperature of the surface of the shaping tube 5011 will be transferred to the U-shaped rubber strip 2 after preliminary shaping, so as to further cool and shape the U-shaped rubber strip 2. At the same time, because the contour of the shaping tube 5011 coincides with the inner side of the U-shaped rubber strip 2, the U-shaped rubber strip 2 is prevented from being unstable in shape during the cooling process. The deformation produced also enables the cooling effect of the cold air to be evenly distributed on the entire inner surface of the U-shaped rubber strip 2. This uniform cooling also avoids deformation of the U-shaped rubber strip 2 due to local overheating or overcooling, and the cold air ejected through the jet hood 5012 and the jet hole 5013 directly acts on the surface of the U-shaped rubber strip 2 to enhance the cooling effect. The wrapping effect of the U-shaped rubber strip 2, that is, the U-shaped rubber strip 2 covers the ejected cold air, ensuring that the cold air fully contacts and cools the U-shaped rubber strip 2, thereby achieving further jet cooling of the U-shaped rubber strip 2, thereby greatly improving the cooling and shaping efficiency and effect of the U-shaped rubber strip 2, and the cold air ejected through the jet hole 5013 not only directly cools the U-shaped rubber strip 2, but also indirectly cools the water in the water tank, thereby achieving repeated use of the water in the cooling water tank 1 without the need to replace or circulate cold water.

[0044] The operating principle of the present invention is described as follows: when the U-shaped rubber strip 2 enters the cooling water tank 1, the cold water performs preliminary cooling and shaping on the U-shaped rubber strip 2, and then the left driving roller 6014 transports the U-shaped rubber strip 2 that has entered the cooling water tank 1 and has been preliminarily shaped in the cold water to the shaping component 501. At the same time, during the operation of the driving belt 6012, the U-shaped rubber strip 2 covering the shaping tube 501 is driven to be conveyed to the right by friction. During this process, the temperature of the surface of the shaping tube 5011 is transferred to the U-shaped rubber strip 2 that has been preliminarily shaped, thereby The U-shaped rubber strip 2 is further cooled and shaped. At the same time, the cold air ejected from the jet hood 5012 and the jet hole 5013 further jets and cools the U-shaped rubber strip 2, thereby greatly improving the cooling and shaping efficiency and effect of the U-shaped rubber strip 2. The cold air ejected from the jet hole 5013 cools the water in the water tank. The U-shaped rubber strip 2 after further cooling and shaping is driven to the upper right by the driving roller 6014. At the same time, the two feeding rollers 6017 rotate relatively to transport the U-shaped rubber strip 2 to the right for discharge.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
