Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a polyester resin sheet cooling device. Background Technology

[0002] Polyester resin compression cooling equipment is a key piece of equipment in the polyester resin production process. It is mainly used to compress and rapidly cool and solidify the molten polyester resin after polymerization, transforming it from a high-viscosity liquid into a sheet-like solid that is easy to store, transport and process.

[0003] When using a polyester resin sheeting cooling device to cool the resin material, the resin that is not completely cooled still has a certain degree of fluidity. This can cause the uncooled resin to move and shift on the cooling steel belt, resulting in uneven thickness of the resin sheet and some resin may even detach from the steel belt, causing waste. Utility Model Content

[0004] This invention provides a polyester resin sheet cooling device to address the problem that when uncooled resin moves on a cooling steel belt, it may flow and shift on the cooling steel belt, leading to uneven thickness of the resin sheet and some resin may even detach from the steel belt, resulting in waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a polyester resin pressing and cooling device, comprising a housing, a support frame welded to the bottom of the housing, a first steel strip and a second steel strip disposed inside the housing, the first steel strip being disposed on top of the second steel strip, both ends of the second steel strip being longer than the first steel strip, a driving assembly disposed on one side of the housing, the driving assembly being capable of driving the first steel strip and the second steel strip to rotate, a scraper cylinder disposed on one side of the top of the first steel strip, the scraper cylinder being rotatably mounted on both sides of the inner wall of the housing, and a limiting device disposed between the first steel strip and the second steel strip, the limiting device being configured by setting two rubber plates that can move between the first steel strip and the second steel strip to limit the two sides of the resin material to be cooled respectively.

[0006] The effect achieved by the above-mentioned components is as follows: by setting two rubber plates and adjusting the two rubber plates so that they abut against the two sides of the resin material to be cooled, the two rubber plates can limit and block the resin material to be cooled, which helps to prevent the resin from flowing and shifting on the cooling steel belt, resulting in uneven thickness of the resin sheet and waste caused by some resin detaching from the steel belt.

[0007] Preferably, the limiting device includes an auxiliary plate, which is fixedly installed on one side of the housing. A rectangular rod is slidably installed on the inner wall of the auxiliary plate. A rubber plate is provided at one end of the rectangular rod. Pressure plates are fixedly installed at the top and bottom of the rubber plate, and the top of one of the pressure plates is fixedly installed at one end of the rectangular rod.

[0008] The effect achieved by the above components is as follows: pushing the bottom pressure plate upward causes the pressure plate to squeeze the rubber plate, causing the rubber plate to deform. Then, pushing the rectangular rod to slide on the inner wall of the auxiliary plate causes the rubber plate connected to the pressure plate to move synchronously until the distance between the two rubber plates matches the width of the resin pressing sheet. When the force applied to the rubber plate is removed, the rubber plate will return to its original position, and the bottom pressure plate and the first steel strip will come into contact. In this way, the rubber plate and the pressure plate can block the resin, which helps to prevent the resin from flowing and shifting on the cooling steel strip.

[0009] Preferably, the rubber sheet has a hollow structure and is made of fluororubber.

[0010] The effects achieved by the above components are as follows: by setting a hollow rubber sheet, the deformation capacity of the rubber sheet can be improved, making it easier to compress the rubber sheet. At the same time, the fluororubber material has high high temperature resistance and can maintain good physical properties even in high temperature environments.

[0011] Preferably, a threaded pin is fixedly installed at the top of the rectangular rod, and a nut is threaded onto the outer surface of the threaded pin, with the nut positioned at the top of the auxiliary plate.

[0012] The effect achieved by the above components is as follows: by rotating the nut, one side of the nut abuts against one side of the auxiliary plate, the nut can fix the rectangular plate and the auxiliary plate, thereby fixing the rubber plate and preventing the rubber plate from shifting.

[0013] Preferably, a washer is provided on one side of the nut, the threaded pin is inserted into the inner wall of the washer, a rubber strip is fixedly installed on one side of the auxiliary plate, the threaded pin is located inside the rubber strip, and one side of the washer abuts against one side of the rubber strip.

[0014] The effect achieved by the above components is that by setting the shim, the contact area between the nut and the auxiliary plate can be increased, and by setting the rubber strip, the friction between the shim and the auxiliary plate can be increased, making the nut less likely to loosen.

[0015] Preferably, the same spring is fixedly installed on the side of the two pressure plates that are close to each other.

[0016] The effect achieved by the above components is as follows: by setting a spring, when the spring is not subjected to other external forces, it will squeeze a pressure plate, so that the bottom pressure plate can fully abut against the second steel strip, thereby ensuring that the pressure plate can block the resin. When the rubber plate is squeezed, it will also squeeze the spring, causing the spring to deform. After the external force on the rubber plate is removed, the spring will also return to its original position and assist the rubber plate in returning to its original position.

[0017] Preferably, the spring has a round rod inside, one end of which is fixedly mounted on one side of one of the pressure plates, and the other pressure plate is slidably mounted on the outer surface of the round rod.

[0018] The effect achieved by the above components is that by setting the round rod, the round rod can limit and guide the spring, which helps to prevent the spring from bending during deformation.

[0019] Preferably, a scale plate is installed on one side of the bottom of the auxiliary plate, and the scale plate is made of transparent material.

[0020] The effect achieved by the above components is that by setting up a scale plate, it is easier to make more precise and intuitive adjustments to the rectangular rod.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting two rubber plates and adjusting them to make them abut against the two sides of the resin material to be cooled, the two rubber plates can limit and block the resin material to be cooled, which helps to prevent the resin from flowing and shifting on the cooling steel belt, thus preventing uneven thickness of the resin sheet and waste caused by some resin detaching from the steel belt.

[0028] Example 1, referring to Figures 1-4 As shown, this embodiment discloses a polyester resin sheet cooling device, including a housing 1. A support frame 2 is welded and installed at the bottom of the housing 1. A first steel strip 3 and a second steel strip 4 are arranged inside the housing 1. The first steel strip 3 is located on top of the second steel strip 4, and both ends of the second steel strip 4 are longer than the first steel strip 3. A driving assembly 5 is arranged on one side of the housing 1, which can drive the first steel strip 3 and the second steel strip 4 to rotate. A scraper cylinder 6 is arranged on one side of the top of the first steel strip 3, and the scraper cylinder 6 is rotatably installed on both sides of the inner wall of the housing 1. A limiting device 7 is arranged between the first steel strip 3 and the second steel strip 4. The limiting device 7 limits the two sides of the resin material to be cooled by setting two rubber plates 73 that can move between the first steel strip 3 and the second steel strip 4. By setting two rubber plates 73, the two rubber plates 73 respectively limit the two sides of the resin material to be cooled. 3. Adjustment is made so that the two rubber plates 73 abut against the two sides of the resin material to be cooled. The two rubber plates 73 can limit and block the resin material to be cooled, which helps to prevent the resin from flowing and shifting on the cooling steel belt, resulting in uneven thickness of the resin sheet and waste caused by some resin detaching from the steel belt. The drive component 5 can be a motor installed on one side of the housing. The motor is connected to the rollers inside the first steel belt 3 and the second steel belt 4 through components such as a reducer. The motor can drive the rollers to rotate, thereby driving the first steel belt 3 and the second steel belt 4 to move. The first steel belt 3 and the second steel belt 4 are equipped with fans. The fans blow air to cool the side of the first steel belt 3 and the second steel belt 4 that are close to each other, thereby cooling the resin material. The cooled resin sheet is scraped by the scraper cylinder 6, causing the resin sheet to detach from the second steel belt 4.

[0029] Reference Figures 2-4As shown, the limiting device 7 includes an auxiliary plate 71, which is fixedly installed on one side of the housing 1. A rectangular rod 72 is slidably installed on the inner wall of the auxiliary plate 71. A rubber plate 73 is provided at one end of the rectangular rod 72. Pressure plates 74 are fixedly installed at the top and bottom of the rubber plate 73. The top of one of the pressure plates 74 is fixedly installed at one end of the rectangular rod 72. Pushing the bottom pressure plate 74 upward causes the pressure plate 74 to squeeze the rubber plate 73, causing the rubber plate 73 to deform. This, in turn, pushes the rectangular rod 72 to slide on the inner wall of the auxiliary plate 71, causing the rubber plate 73 connected to the pressure plate 74 to move synchronously until both rubber plates move together. The distance between the plates 73 is adapted to the width of the resin sheet. When the force applied to the rubber plate 73 is removed, the rubber plate 73 will return to its original position, and the bottom pressure plate 74 will abut against the first steel strip 3. Thus, the rubber plate 73 and the pressure plate 74 can block the resin, which helps to prevent the resin from flowing and shifting on the cooling steel strip. The rubber plate 73 has a hollow structure and is made of fluororubber. By setting the hollow structure of the rubber plate 73, the deformation capacity of the rubber plate 73 can be improved, making it easier to compress the rubber plate 73. At the same time, the fluororubber material has high high temperature resistance and can maintain good physical properties in high temperature environments.

[0030] Reference Figure 2 and Figure 3 As shown, a threaded pin 75 is fixedly installed at the top of the rectangular rod 72, and a nut 76 is threadedly connected to the outer surface of the threaded pin 75. The nut 76 is located on the top of the auxiliary plate 71. By rotating the nut 76, one side of the nut 76 abuts against one side of the auxiliary plate 71, thus fixing the rectangular plate and the auxiliary plate 71, and consequently fixing the rubber plate 73, which helps prevent the rubber plate 73 from shifting. A washer 77 is provided on one side of the nut 76, and the threaded pin 75 is inserted into the inner wall of the washer 77. A rubber strip 78 is fixedly installed on one side of the auxiliary plate 71, and the threaded pin 75 is located inside the rubber strip 78. One side of the washer 77 abuts against one side of the rubber strip 78. By providing the washer 77, the contact area between the nut 76 and the auxiliary plate 71 can be increased. At the same time, by providing the rubber strip 78, the friction between the washer 77 and the auxiliary plate 71 can be increased, making it less likely for the nut 76 to loosen.

[0031] Reference Figure 2 and Figure 3As shown, a spring 79 is fixedly installed on one side of the two pressure plates 74 that are close to each other. By setting the spring 79, when there is no other external force, the spring 79 will squeeze one of the pressure plates 74, so that the bottom pressure plate 74 can fully abut against the second steel strip 4, thereby ensuring that the pressure plate 74 can block the resin. When the rubber plate 73 is squeezed, the spring 79 will also be squeezed, causing the spring 79 to deform. After the external force on the rubber plate 73 is removed, the spring 79 will also return to its original position and assist the rubber plate 73 in returning to its original position. A round rod 710 is set inside the spring 79. One end of the round rod 710 is fixedly installed on one side of one of the pressure plates 74, and the other pressure plate 74 is slidably installed on the outer surface of the round rod 710. By setting the round rod 710, the round rod 710 can limit and guide the spring 79, which helps to prevent the spring 79 from bending during deformation.

[0032] Reference Figure 2 and Figure 4 As shown, a scale plate 711 is installed on one side of the bottom of the auxiliary plate 71. The scale plate 711 is made of transparent material. By setting the scale plate 711, it is convenient to make more precise and intuitive adjustments to the rectangular rod 72.

[0033] Working principle: Pushing the bottom pressure plate 74 upward causes it to compress the rubber plate 73 and spring 79, deforming them. This causes the rectangular rod 72 to slide along the inner wall of the auxiliary plate 71, moving the rubber plate 73 connected to the pressure plate 74 synchronously until the distance between the two rubber plates 73 matches the width of the resin pressing sheet. Removing the force applied to the rubber plate 73 causes it to return to its original position, bringing the bottom pressure plate 74 into contact with the first steel strip 3. Rotating the nut 76 causes the washer 77 on one side of the nut 76 to contact the rubber strip 78 on one side of the auxiliary plate 71, thus fixing the rectangular plate and the auxiliary plate 71 and the rubber plate 73. This helps prevent the rubber plate 73 from shifting. The rubber plate 73 and the pressure plate 74 also block the resin, preventing it from flowing and shifting on the cooling steel strip.
