Description

Technical Field

[0001] The utility model relates to the technical field of PVC casing production, in particular to a pre-cooling bracket for a PVC casing production line. Background Technique

[0002] A PVC casing is a kind of casing made of PVC material, mainly used to protect the pipes on the surfaces of electric wires and water pipes. During the production process of PVC pipes, the PVC raw materials need to be first fed into an extruder. The extruder heats and melts the raw materials and extrudes the molten PVC material from the machine head to obtain a formed PVC pipe. To shape the PVC pipe, water cooling is also required, and for this purpose, a pre-cooling bracket is used to assist in its cooling and shaping.

[0003] For example, the utility model with the application number 202120038703.9 discloses a pre-cooling bracket for a PVC electrical casing production line. This pre-cooling bracket for the casing production line, through an open semi-ring design, after the PVC wire pipe blank comes out of the extruder and is cooled and shaped, it can meet the requirement of cleaning the precipitates without stopping the machine, and is convenient to disassemble, ensuring that the appearance of the pipe material is flat and smooth. The semi-circular bracket is used in cooperation with spray cooling, so that the PVC wire pipe blank can be evenly cooled and quickly shaped from the material to the formed state, and can solve the problem that the bending rigidity of the pipe blank is insufficient and ensure the production stability. However, in the use of the pre-cooling bracket for the casing production line similar to the above document, since the contact structural surface between the semi-circular bracket and the PVC casing is still relatively large, and at the same time, using the driving force generated by the extruder to promote the forward movement of the PVC casing, there is a large structural friction between the PVC casing and the semi-circular bracket, which will affect the surface of the PVC casing.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a pre-cooling bracket for a PVC casing production line is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pre-cooling bracket for a PVC casing production line to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A pre-cooling bracket for a PVC casing production line includes a bracket assembly and a transmission frame group. The transmission frame group is obliquely arranged and installed on one side of the bracket assembly, and a pre-cooling assembly is installed on the side of the bracket assembly far from the transmission frame group. Moreover, a return pool is arranged at the bottom of the bracket assembly, and flow-blocking covers are vertically installed on the left and right sides of the return pool. The transmission frame group includes a transmission roller, an anti-sticking sleeve, a micro motor, and a damping slider. The outer surface of the transmission roller is sleeved with an anti-sticking sleeve, one end of the transmission roller is connected to the micro motor, and one end of the micro motor far from the transmission roller is connected to the damping slider.

[0007] Furthermore, the bracket assembly includes a right-angle frame, a fixed frame, a stabilizing frame and a guide rod. The right-angle frame is connected to the fixed frame at the top and bottom, and the stabilizing frame is obliquely installed at both ends of the fixed frame. The guide rods are horizontally installed at the upper and lower ends of the stabilizing frame.

[0008] Furthermore, the right-angle frame and the fixed frame are connected by welding, and the fixed frame is horizontally connected to the two ends of the right angle of the right-angle frame respectively, and the right-angle frame is arranged at the front and rear ends of the fixed frame.

[0009] Furthermore, the guide rod horizontally passes through the middle of the damping slider, and the damping slider is arranged at the upper and lower ends of the transmission roller, and the damping slider is used for translation adjustment of the transmission roller along the surface of the guide rod.

[0010] Furthermore, the precooling assembly includes a sliding seat, a filter pump and a delivery pipe. The filter pump is installed on one side of the sliding seat, and the bottom of the filter pump is connected to the delivery pipe.

[0011] Furthermore, the precooling component also includes an adjusting hose and an atomizing nozzle. The top output end of the filter pump is connected to the adjusting hose, and the atomizing nozzle is installed at one end of the adjusting hose away from the filter pump.

[0012] Furthermore, the sliding seat is slidably connected to the side surface of the fixed frame connected to the top end of the right-angle frame, and the end of the delivery pipe away from the filter pump extends to the inner bottom side of the reflow tank.

[0013] Furthermore, the regulating hose is used to adjust the direction of the atomizing nozzle, and the baffle is used to block the coolant sprayed by the pre-cooling component, and the pre-cooling component is arranged and installed on the side of the bracket component.

[0014] The utility model provides a precooling bracket for a PVC casing production line, which has the following beneficial effects:

[0015] 1. According to the utility model, after the PVC sleeve is output from the extrusion port of the extruder, the support assembly cooperates with the transmission frame assembly to provide good structural support for the PVC sleeve. At the same time, the transmission roller connected thereto is driven to rotate axially under the operation of the micro motor, thereby driving the PVC sleeve to translate. At this time, under the synchronous operation of the pre-cooling assembly, as the PVC sleeve is extruded, the cooling water inside the reflux pool is quickly extracted through the filter pump, and is quickly sprayed onto the surface of the PVC sleeve by the atomizing nozzle. At this time, in conjunction with the open structure of each component, the PVC sleeve can be quickly cooled to help it to form, and it can be quickly transported to the downstream processing equipment. In addition, the anti-sticking sleeve sleeved on the surface of the transmission roller cooperates with the spraying of cooling water by the pre-cooling assembly to avoid the adhesion of the PVC sleeve just discharged from the output end of the extruder to the surface of the transmission roller as much as possible, thereby ensuring the overall quality of the PVC sleeve.

[0016] 2. In this utility model, flow-blocking covers are symmetrically arranged on the left and right sides of the reflux pool. On the one hand, it can block the cooling water sprayed by the precooling component as much as possible to avoid the coolant from scattering everywhere. On the other hand, the blocked cooling water can be converged by the flow-blocking covers and made to flow back into the interior of the reflux pool, which can not only improve the operating environment of the device, but also reduce the waste of cooling water. And by extending the bottom end of the delivery pipe to the bottom side inside the reflux pool, the refluxed cooling water can be quickly pumped in real time, so as to recycle the cooling water, thereby reducing the operating cost of the device as much as possible. In addition, through the adjustable structure of the adjusting hose, the atomizing nozzle can be oriented to an appropriate position, which not only controls the spraying range of the cooling water, but also ensures the cooling effect of the PVC sleeve.

[0017] 3. In this utility model, by using the damping slider, the entire drive frame group can move horizontally along the surface of the guide rod to adjust the distance between the drive frame groups, so as to provide convenience for the conveying of the PVC sleeve as much as possible and ensure that the PVC sleeve will not get stuck during the conveying process. In addition, by using the sliding seat, the entire precooling component can move horizontally along the side surface of the fixed frame, while controlling the distance between the precooling components, ensuring the effectiveness of cooling the PVC sleeve during its movement, ensuring that it can be quickly solidified and formed, and preventing unnecessary deformation during the conveying process.

[0023] The following further describes the implementation mode of the present utility model in detail in conjunction with the attached drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] As Figures 1 to 4 shown, a pre-cooling bracket for a PVC casing production line includes a bracket assembly 1 and a transmission frame group 2. The transmission frame group 2 is installed in an inclined arrangement on one side of the bracket assembly 1, and a pre-cooling assembly 3 is installed on the side of the bracket assembly 1 away from the transmission frame group 2. Moreover, a return pool 4 is provided at the bottom of the bracket assembly 1, and flow-blocking covers 5 are vertically installed on the left and right sides of the return pool 4. The transmission frame group 2 includes a transmission roller 201, an anti-sticking casing 202, a micro motor 203, and a damping slider 204. The outer surface of the transmission roller 201 is sleeved with the anti-sticking casing 202, and one end of the transmission roller 201 is connected to the micro motor 203. Moreover, one end of the micro motor 203 away from the transmission roller 201 is connected to the damping slider 204. When the PVC casing is output from the extrusion port of the extruder, at this time, the bracket assembly 1 cooperates with the transmission frame group 2 to provide good structural support for the PVC casing. At the same time, under the operation of the micro motor 203, the connected transmission roller 201 is driven to rotate axially, thereby driving the PVC casing to translate. The cooling water inside the return pool 4 is quickly pumped out through the filtration pump 302 and quickly sprayed onto the surface of the PVC casing by the atomizing nozzle 305, so that the PVC casing is quickly solidified and formed.

[0025] As Figures 1 to 4 shown, the bracket assembly 1 includes a right-angle frame 101, a fixed frame 102, a stabilizing frame 103, and a guide rod 104. The upper and lower parts of the right-angle frame 101 are both connected to the fixed frame 102, and the left and right ends of the fixed frame 102 are both installed obliquely with the stabilizing frame 103. Moreover, the guide rod 104 is horizontally installed at the upper and lower ends of the stabilizing frame 103. The right-angle frame 101 and the fixed frame 102 are connected by welding, and the fixed frame 102 is horizontally connected to the two ends of the right-angle of the right-angle frame 101 respectively. Moreover, the right-angle frame 101 is arranged at the front and rear ends of the fixed frame 102. The guide rod 104 horizontally penetrates through the middle of the damping slider 204, and the damping slider 204 is arranged at the upper and lower ends of the transmission roller 201. Moreover, the damping slider 204 is used for the transmission roller 201 to translate and adjust along the surface of the guide rod 104. The blocked cooling water can be converged by the flow-blocking cover 5 and made to flow back into the interior of the return pool 4 again. And by extending the bottom end of the delivery pipe 303 to the bottom side inside the return pool 4, the cooled water after flowing back can be quickly pumped out in real time, so as to recycle the cooling water.

[0026] As Figures 1 to 4As shown in the figure, the pre-cooling assembly 3 includes a sliding seat 301, a filtration pump 302, and a delivery pipe 303. A filtration pump 302 is installed on one side of the sliding seat 301, and a delivery pipe 303 is connected to the bottom of the filtration pump 302. The pre-cooling assembly 3 further includes an adjustment hose 304 and an atomizing nozzle 305. The top output end of the filtration pump 302 is connected to the adjustment hose 304, and an atomizing nozzle 305 is installed at one end of the adjustment hose 304 away from the filtration pump 302. The sliding seat 301 is slidably connected to the side surface of a fixing bracket 102 connected to the top end of a right-angle bracket 101. One end of the delivery pipe 303 away from the filtration pump 302 extends to the inner bottom side of the reflux pool 4. The adjustment hose 304 is used to adjust the orientation of the atomizing nozzle 305, and a flow-blocking cover 5 is used to block the coolant sprayed by the pre-cooling assembly 3. The pre-cooling assemblies 3 are arranged and installed on the side of the bracket assembly 1. By using the damping slider 204, the entire drive frame group 2 can be horizontally moved along the surface of the guide rod 104. Additionally, by using the sliding seat 301, the entire pre-cooling assembly 3 can be horizontally moved along the side surface of the fixing bracket 102, thereby ensuring that while the PVC sleeve is rapidly cooled, the problem of jamming during transportation is prevented.

[0027] In summary, as Figures 1 to 4 shown in the figure, when the pre-cooling bracket of this PVC sleeve production line is in use, first, according to requirements, the drive frame group 2 and the pre-cooling assembly 3 can be respectively slid and adjusted along the surfaces of the guide rod 104 and the fixing bracket 102 by using the damping slider 204 and the sliding seat 301 respectively, so as to ensure the optimal distance for processing the PVC sleeve;

[0028] After that, the extruder will heat and melt the raw materials injected into it, and then extrude the molten PVC material from the machine head, thereby obtaining a formed PVC pipe. At this time, the entire bracket assembly 1 and the drive frame group 2 are arranged on one side of the extrusion head and maintain an appropriate height with the discharged PVC sleeve;

[0029] As the PVC sleeve is discharged, the drive frame group 2 and the pre-cooling assembly 3 have been pre-started at this time. The filtration pump 302 installed on one side of the sliding seat 301 quickly extracts the cooling water inside the reflux pool 4 through the delivery pipe 303 at the bottom and filters it in real time to prevent impurities in the water from affecting the surface of the PVC pipe that has not been completely solidified and formed. Then, under the delivery of the adjustment hose 304, the cooling water enters the atomizing nozzle 305, and finally is completely sprayed onto the surface of the PVC sleeve through the atomizing nozzle 305. With the cooperation of several groups of pre-cooling assemblies 3 arranged symmetrically on the left and right, the PVC sleeve is cooled and formed as quickly as possible;

[0030] At the same time, the micro-motor 203 will drive the transmission roller 201 sleeved with an anti-sticking sleeve 202 on its surface to rotate, thereby providing a transmission function for the PVC sleeve in contact with it, and transporting it to downstream equipment for further processing while it is being cooled;

[0031] During the operation of the entire pre-cooling assembly 3, some of the sprayed cooling water will splash onto the inner wall surface of the flow-blocking cover 5. After converging into water droplets, under the action of gravity, they will flow downward and finally flow into the lower return pool 4 for the pre-cooling assembly 3 to recycle.

[0032] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention so as to design various embodiments with various modifications suitable for specific purposes.
