Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizing machine auxiliary, and more specifically to a vulcanizing machine hot plate cooling device. Background Art

[0002] A vulcanizer is a machine that vulcanizes various rubber and plastic products. It has functions such as timed mold locking, automatic pressure replenishment, automatic temperature control, automatic timing, and time alarm. The vulcanizer vulcanizes rubber and plastic products through hot plates. After vulcanization, the hot plates need to be quickly cooled by a cooling device, thereby reducing the time for converting rubber product types. It can also greatly shorten the vulcanization cycle and save production time and energy.

[0003] Based on the above, the inventors found that the existing cooling device mainly passes the cooling pipe through the inside of the hot plate and cooperates with the coolant to cool down the temperature. However, during the circulation of the coolant, precipitated impurities will be produced. The long-term accumulation of impurities will affect the cooling effect. Therefore, in view of this, the existing structure is studied and improved, and a vulcanizer hot plate cooling device is provided, in order to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical issues to be solved

The present invention provides a filter component that is easy to replace, which can filter the circulating coolant, reduce the problem of impurity precipitation and accumulation in the coolant, and extend the service life of the cooling device. A sealing component is provided to keep the connecting pipe in a sealed state when the filter component is replaced, thereby preventing dust and impurities from reversely penetrating into the interior of the connecting pipe and reducing the problem of coolant pollution.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0027] Example

[0028] See also Figure 1-5A vulcanizing machine hot plate cooling device comprises a heating plate 1 and a cooling tank 2.

The delivery pump 3 and the reflux pump 4 are fixedly connected to a connecting pipe 6 at one end on the outer side. A fixing cylinder 7 is provided at the center of the opposite surfaces of the two ends of the cooling pipe 5 and the upper ends of the two connecting pipes 6. A first clamping sleeve 8 and a second clamping sleeve 9 are respectively provided at the two ends of the fixing cylinder 7. A filter element 10 is fixedly connected to the center of the fixing cylinder 7. A sealing mechanism 11 is provided at the inner side of the upper end of the connecting pipe 6.

[0029] The sealing mechanism 11 includes a group of sliding plates 12 arranged in a circular array, a pressure groove 13 is opened at the inner end of the sliding plate 12, and a guide rod 14 is penetrated at the outer end of the sliding plate 12, and a sealing spring 15 is sleeved on the outer side of the guide rod 14. In order to keep the connecting pipe 6 in a sealed state when the filter component is replaced and prevent dust and impurities from penetrating into the interior of the connecting pipe 6, the sealing mechanism 11 is provided.

[0030] See also Figure 1 The cooling tank 2 is located below the heating plate 1, and the interior of the cooling tank 2 is filled with coolant. The vulcanization work is performed through the heating plate 1. After the vulcanization work is completed, the delivery pump 3 and the reflux pump 4 are started to allow the coolant to enter the cooling pipe 5 through the first connecting pipe 6. The coolant flows inside the cooling pipe 5 and absorbs heat and cools down, and then enters the cooling tank 2 through the second connecting pipe 6 and the reflux pump 4.

[0031] See also Figure 3 The inner ends of the two first clamping sleeves 8 and the second clamping sleeve 9 are fixedly connected to the threaded ring, and the threaded ring is threadedly connected to the fixed tube 7. Rotating the clamping sleeve drives the threaded ring inside the fixed tube 7 to adjust the position of the clamping sleeve.

[0032] See also Figure 3 The outer end of the first clamping sleeve 8 is clamped with the connecting pipe 6, and the outer end of the second clamping sleeve 9 is clamped with the cooling pipe 5. The fixing work of the fixing tube 7 is completed by clamping the outer end of the first clamping sleeve 8 with the connecting pipe 6 and the outer end of the second clamping sleeve 9 with the cooling pipe 5. Conversely, the outer end of the first clamping sleeve 8 is separated from the connecting pipe 6, and the outer end of the second clamping sleeve 9 is separated from the cooling pipe 5, completing the disassembly work of the fixing tube 7.

[0033] See also Figure 4 The first clamping sleeve 8 is fixedly connected to an extrusion block at one end face on the outside, and the extrusion block is adapted to the pressure groove 13. After the first clamping sleeve 8 enters the connecting pipe 6, it squeezes the pressure groove 13, thereby causing the sliding plate 12 to slide outward.

[0034] See also Figure 5The sliding plate 12 is located at the upper end of the connecting tube 6 and is slidably connected to the connecting tube 6. The sides of two adjacent sliding plates 12 are fitted together. The sliding plates 12 are separated to make the interior of the connecting tube 6 unobstructed, which facilitates the flow of the coolant.

[0035] See also Figure 5 One end of the guide rod 14 and one end of the sealing spring 15 are fixedly connected to the inner surface of the upper end of the connecting tube 6, and the other end of the sealing spring 15 is fixedly connected to the sliding plate 12. When the first clamping sleeve 8 is separated from the connecting tube 6, the pressure groove 13 loses pressure, and the sliding plate 12 returns to slide under the action of the sealing spring 15. The sides of multiple sliding plates 12 are fitted together to make the connecting tube 6 in a sealed state.

[0036] During use: vulcanization is performed through the heating plate 1. After the vulcanization is completed, the delivery pump 3 and the reflux pump 4 are started to allow the coolant to enter the cooling tube 5 through the first connecting tube 6. The coolant flows inside the cooling tube 5 and absorbs heat to cool down. Then, the coolant enters the cooling tank 2 through the second connecting tube 6 and the reflux pump 4. The coolant passes through the fixed cylinder 7 during the flow process, and the filter element 10 filters the impurities. When the vulcanization is completed, the clamping sleeve is rotated to drive the threaded ring inside the fixed cylinder 7 to separate the outer end of the first clamping sleeve 8 from the connecting tube 6, and the outer end of the second clamping sleeve 9 from the cooling tube 5, completing the disassembly of the fixed cylinder 7. When the first clamping sleeve 8 is separated from the connecting tube 6, the pressure groove 1 3 loses pressure, the sliding plate 12 returns to slide under the action of the sealing spring 15, and the sides of the multiple sliding plates 12 are fitted together, so that the connecting pipe 6 is in a sealed state to prevent dust and impurities from penetrating into the inside of the connecting pipe 6. Then, the new fixing cylinder 7 is placed between the cooling pipe 5 and the connecting pipe 6, and the two clamping sleeves are rotated in the opposite direction, so that the outer end of the first clamping sleeve 8 is clamped with the connecting pipe 6, and the outer end of the second clamping sleeve 9 is clamped with the cooling pipe 5, and the fixing work of the fixing cylinder 7 is completed. After the first clamping sleeve 8 enters the inside of the connecting pipe 6, it squeezes the pressure groove 13, thereby making the sliding plate 12 slide outward, and the sliding plates 12 are separated to make the inside of the connecting pipe 6 unobstructed, which is convenient for the flow of coolant and the subsequent cooling work.
