Description

Technical Field

[0001] The utility model relates to the technical field of wall cloth processing, in particular to extrusion equipment for processing PVC wall cloth. Background Art

[0002] The surface of PVC wall cloth material is mainly made of polyvinyl chloride resin and a cross mesh bottom, and can be processed by deep embossing, printing, top printing and washing.

[0003] An existing patent (publication number CN218286823U) and an extrusion device for processing PVC wall cloth, in which the pump box of this patent is started to generate negative pressure inside the water-pumping sleeve, thereby squeezing and dehydrating the wall cloth, and the water flows into the water-pumping sleeve, and is finally transferred to the storage box to achieve preliminary compression and dehydration. The pressing plate moves synchronously with the cloth, and there will be no speed difference, thereby ensuring that no wrinkles are generated and improving the compression and dehydration effect. Since the pressing plate is in contact with the cloth and moves synchronously, the wear of the cloth during transportation can be greatly reduced, and the overall transportation and processing efficiency can be improved. However, the wall cloth itself has a certain water absorption capacity, so that the wall cloth still has moisture after extrusion, and the dehydration effect cannot be achieved. At the same time, the outer wall of the extrusion component in the above-mentioned patent will absorb moisture, and the moisture will also affect the extrusion and dehydration effect.

[0004] Therefore, we propose an extrusion device for PVC wall cloth processing, which is beneficial to reduce the moisture in the wall cloth and avoid the outer wall of the extruded component always absorbing moisture and affecting the effect of extrusion dehydration. Utility Model Content

[0007] The air outlet of the first blower is connected to the main air pipe, a water blowing port is provided at the bottom of the main air pipe, both sides of the main air pipe are connected to diversion pipes, airflow is arranged at the ends of the diversion pipes, and the diversion pipes on both sides correspond to the first extrusion roller on the upper side and the second extrusion roller on the upper side respectively.

[0008] Furthermore: a second water receiving box is placed inside the shell, and the position of the second water receiving box corresponds to the position of the main air pipe. The moisture in the wall cloth passes through the airflow in the main air pipe and passes through the water blowing port to fall into the second water receiving box.

[0009] Further: the air outlet pipe of the second blower is connected to two groups of drying pipes respectively, and the two groups of drying pipes are respectively close to the first extrusion roller on the lower side and the second extrusion roller on the lower side, and the two groups of drying pipes are equidistantly provided with drying ports on the side walls close to the first extrusion roller on the lower side and the second extrusion roller on the lower side.

At the same time, the high-speed air flow will accelerate the evaporation of the moisture in the wall cloth, which is beneficial to improve the dehydration effect of the wall cloth and avoid the hygroscopicity of the wall cloth making it difficult to quickly discharge the moisture in the wall cloth.

[0016] 2) The extrusion equipment for processing PVC wall cloth of the utility model is provided with a shunt pipe and a second blower.

[0024] See also Figure 1-4 The utility model provides a technical solution: an extrusion device for processing PVC wall cloth, comprising a shell 1, wherein a first extrusion roller 21 and a second extrusion roller are respectively arranged on the left and right sides of the shell 1, wherein the first extrusion roller 21 and the second extrusion roller are both two, and the two groups of the first extrusion rollers 21 distributed up and down and the two second extrusion rollers distributed up and down respectively correspond to the two ends of the wall cloth 4 for extrusion and rotation, the two groups of the first extrusion rollers 21 and the two groups of the second extrusion rollers are located at the same horizontal height, the shaft body of the first extrusion roller 21 on the lower side is connected to a first drive motor 2, the shaft body of the first drive motor 2 is connected to the first extrusion roller 21 on the upper side through a belt transmission, the shaft body of the second extrusion roller on the lower side is connected to a second drive motor 3, and the shaft body of the second drive motor 3 is connected to the second extrusion roller on the upper side through a belt transmission;

[0025] The first driving motor 2 and the second driving motor 3 respectively drive the first squeezing roller 21 and the second squeezing roller to rotate, and the two groups of the first squeezing rollers 21 and the second squeezing rollers clamp and squeeze the wall cloth 4 to squeeze out the moisture in the wall cloth 4, thereby achieving the purpose of dehydrating the wall cloth 4.

[0026] The wall cloth 4 passes through two groups of openings 11 on the outer wall of the housing 1. The housing 1 has a built-in water blowing assembly 6. The water blowing assembly 6 includes a first blower 61 and a second blower 67.

[0027] The air outlet of the first blower 61 is connected to a main air pipe 62, a water blowing port 68 is provided at the bottom of the main air pipe 62, both sides of the main air pipe 62 are connected to a shunt pipe 63, airflow is arranged at the end of the shunt pipe 63, and the shunt pipes 63 on both sides correspond to the first squeezing roller 21 on the upper side and the second squeezing roller on the upper side respectively;

[0028] The first blower 61 is started to suck in the air flow and then pressurize it and blow it out, and then the air flow is ejected through the water blowing port 68 of the main air pipe 62, and then the high-speed air flow impacts the wall cloth 4, and the water is blown out from the gaps in the wall cloth 4, and then the water falls into the second water receiving box 5, and the high-speed air flow accelerates the evaporation of the water in the wall cloth 4;

[0030] When the first blower 61 is started, part of the air flow enters the diversion pipe 63 and is discharged from the air port 65. This air flow corresponds to the upper first extrusion roller 21 and the upper second extrusion roller respectively.

This air flow corresponds to the lower first extrusion roller 21 and the lower second extrusion roller respectively, thereby quickly drying the moisture on the outer wall of the extrusion component to avoid the extrusion component and the wall cloth 4 being in a wet state all the time when they are in contact.

[0031] Among them, a second water receiving box 5 is placed inside the outer shell 1, and the position of the second water receiving box 5 corresponds to the position of the main air pipe 62. The moisture in the wall cloth 4 passes through the airflow in the main air pipe 62 and the water blowing port 68 to fall into the second water receiving box 5, thereby preventing the moisture from falling into the inner part of the outer shell 1 and centrally processing the dehydrated moisture.

It should be particularly noted that in the case of the assembly line operation of the wall cloth 4, the first squeezing roller 21 and the second squeezing roller do not need a driving assembly, that is, the first drive motor 2 and the second drive motor 3 are not needed, and the wall cloth 4 can be passed between the first squeezing roller 21 and the second squeezing roller through the guide structure;

[0034] The first blower 61 is started to suck in the air flow and then pressurize it and blow it out, and then the air flow is ejected through the water blowing port 68 of the main air pipe 62, and then the high-speed air flow impacts the wall cloth 4, and the water is blown out from the gaps in the wall cloth 4, and then the water falls into the second water receiving box 5, and the high-speed air flow accelerates the evaporation of the water in the wall cloth 4;

[0035] When the first blower 61 is started, part of the air flow enters the diversion pipe 63 and is discharged from the air port 65. This air flow corresponds to the upper first extrusion roller 21 and the upper second extrusion roller respectively. By starting the second blower 67, the air flow is discharged through the drying port 66 of the drying pipe 64. This air flow corresponds to the lower first extrusion roller 21 and the lower second extrusion roller respectively, thereby quickly drying the moisture on the outer wall of the extrusion component to avoid the extrusion component and the wall cloth 4 being in a wet state all the time when they are in contact.
