Description

Technical Field

[0001] The utility model belongs to the field of PVC beadings, and particularly relates to a cooling device for PVC beading production. Background Technique

[0002] PVC is the abbreviation of polyvinyl chloride, which is a plastic material and one of the quite popular and widely used synthetic materials in the world today; its global usage ranks second among various synthetic materials. Commonly used PVC beadings are divided into inside corner beadings, outside corner beadings, high-low beadings, flat-edge beadings, etc. As the name implies, the inside corner beading is used to press the gap of the inside corner (for example: the inside corner of the indoor wall), the outside corner beading is used for the closing of the outside corner, the high-low beading is used for the closing of the floor with height difference indoors (such as: the floor with height difference at the intersection of the bedroom and the living room uses the high-low beading). The flat-edge beading is used for the closing of the expansion joint when laying a large area of floor. The beading mainly plays a decorative role in life.

[0003] At present, the Chinese utility model with the publication number of CN211823325U discloses a cooling device for the production of door outside beadings, including a main box body and a base. A support column is fixedly connected to the top of the base, a bearing plate is slidably sleeved on the support column, and the bearing plate is connected to the top of the base through a hydraulic cylinder. An inlet is arranged at one end of the main box body away from the bearing plate, and a fixing plug is threadedly connected in the inlet. A plurality of symmetrically arranged heat conducting rods are fixedly inserted into the inner bottom of the main box body, one end of the heat conducting rod penetrates through the inner wall of the main box body and extends outwards, and two symmetrically arranged copper tubes are fixedly inserted into the inner top of the main box body. One end of the two copper tubes away from the main box body is fixedly connected through a heat dissipation plate. In the utility model, through the setting of the adjustable heat dissipation mechanism, the device can be freely adjusted according to the height of the production device, thereby improving the cooling effect of the cooling mechanism.

[0004] In the height adjustment of the cooling device, the support column is used to guide the longitudinal movement of the main box body. However, in use, if the bottom space of the external production equipment is small, although the main box body is at a lower position, the guide rod still occupies the bottom space, which brings limitations to the use. At the same time, in the heat dissipation of the heat conducting rod and the heat dissipation fin, the cooling effect is general, and there is a situation of poor cooling efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cooling device for PVC beading production, which has the advantages that when not in use, it occupies a small space, is more convenient for the use of the bottom of the equipment, increases the use flexibility and compatibility, and is convenient for improving the cooling efficiency in the production of PVC beadings.

[0006] The above technical object of the utility model is achieved by the following technical solutions: A cooling device for PVC strip production, including a housing, an inner housing is provided inside the housing, a screw rod is rotatably connected to the bottom inside the housing through a bearing, both ends of the surface of the screw rod are threadedly connected with threaded blocks, the top of each of the two threaded blocks is rotatably connected with a connecting rod rotatably connected to the bottom of the inner housing through a rotating shaft, the top of each of the two threaded blocks is rotatably connected with a connecting rod through a rotating shaft, the other end of the connecting rod is rotatably connected with a slider three, a sliding groove two for the slider three to slide is opened at the bottom of the inner housing, guide rods are fixedly installed on both sides of the top of the housing, semiconductor refrigeration sheets are embedded and installed at the bottom inside the inner housing, a heat dissipation fan is fixedly installed at the bottom of the semiconductor refrigeration sheet, a cover body is bolted to the top of the inner housing, and a contact plate is provided on the top of the cover body.

[0007] Adopting the above technical solution: When cooling is required during the production of PVC strips, the wheel body cooperates with the outer shell to move. After moving the device directly below the object to be cooled, the height of the contact plate is then adjusted. Rotating the knob will drive the connecting rod and the second bevel gear to rotate. The second bevel gear will drive the first bevel gear and the screw rod to rotate synchronously. The rotation of the screw rod will drive the two threaded blocks to move. Due to the reverse thread design at both ends of the screw rod, the two threaded blocks will move in opposite directions. The sliding connection between the first slider and the first chute is used to guide the movement of the threaded block. When the two threaded blocks approach each other, the connecting rod will be driven to rotate. The angular change of the two connecting rods causes the inner shell to change in height. At the same time, the third slider and the second chute cooperate with one end of the connecting rod to move in position. The inner shell will drive the contact plate to gradually move longitudinally until the contact plate contacts the bottom of the object to be cooled. At the same time, during the movement of the inner shell, the guide block remains stationary on the surface of the guide rod, and the slide rail slides inside the second slider following the movement of the inner shell. After the second slider is located at one end of the slide rail, the first limiting block cooperates with both ends of the slide rail for limiting to prevent the second slider from slipping off the surface of the slide rail. At the same time, the setting of the first limiting block will also drive the second slider and the guide block to move on the surface of the guide rod. Through this setting, the movement of the inner shell can be guided. The second limiting block cooperates with one end of the guide rod for limiting to prevent the guide block from slipping off the surface of the guide rod. And when the device is retracted and not in use, it occupies less space, is more convenient for using the bottom of the equipment, and increases the flexibility and compatibility of use. When cooling is required during the production of PVC strips, first, the inner shell is filled with coolant by opening the cover body, and then the coolant is cooled by the operation of the semiconductor refrigeration sheet. The cooling fan cooperates with the semiconductor refrigeration sheet for heat dissipation, and the heat dissipation holes cooperate with the cooling fan for ventilation and heat dissipation. The temperature of the coolant will be transmitted to the heat conduction rod, and then the heat conduction rod cooperates with the contact plate for temperature conduction. The heat conduction rod cooperates with the coolant inside the inner shell for temperature field conduction. The contact plate contacts the object to be cooled in the production process and transfers the temperature to the object. When the coolant needs to be replaced, the pipeline cooperates with the coolant inside the inner shell for drainage, and the solenoid valve cooperates with the pipeline for control. Through this setting, it is convenient to improve the cooling efficiency in the production of PVC strips.
