Description

Technical Field

[0001] This utility model relates to the field of urinary catheter processing technology, and in particular to an air blowing and feeding device for a urinary catheter extrusion production line. Background Technology

[0002] During the processing of urinary catheters, they need to be continuously extruded through an extrusion production line, and after being cut, they are output through a conveyor belt and collected manually.

[0003] This invention is primarily aimed at longer urinary catheters. Because catheter production is continuous, after a product is cut, it enters a conveyor belt, which moves the catheter. If workers don't retrieve it in time, it will fall to the ground. Even if a storage box is placed at the end of the conveyor belt for catheters that fall in, the length of the catheter causes significant bending and deformation. This results in the catheters falling into the collection box being tangled and messy, making subsequent cleaning very inconvenient and easily causing the catheters at the bottom to be deformed, affecting the product quality. Utility Model Content

[0004] The purpose of this invention is to provide an air-blowing feeding device for a catheter extrusion production line. By blowing air onto the side of the catheter, the feeding direction of the catheter is perpendicular to the transmission direction during catheter processing. A machine is also provided for temporary storage of the blown-off catheters, so that workers can easily pick them up.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a blow-feeding device for a catheter extrusion production line, comprising a conveyor belt for receiving the cut catheter, a blow-feeding mechanism disposed on the rear side of the conveyor belt, a machine platform disposed on the front side of the conveyor belt, and a buffer blocking mechanism disposed on the front side of the conveyor belt to prevent the catheter from flying out during the process of being blown down onto the machine platform; the blow-feeding mechanism comprises two first supports disposed on the machine frame of the conveyor belt, a blow-feeding pipe disposed between the two first supports and disposed along the length direction of the conveyor belt, and a blow-feeding pipe The air intake pipe is connected to an external compressed air source, and an air intake solenoid valve is located in the middle of the air intake pipe. The air blowing pipe has multiple air blowing holes arranged in an array along its length and inclined towards the upper surface of the conveyor belt. The buffer blocking mechanism includes two second supports located in front of the conveyor belt and a hollow baffle groove located between the two second supports. The end of the baffle groove near the conveyor belt is located above the conveyor belt, and the end near the machine is inclined downward. The end face of the baffle groove near the conveyor belt and for the catheter to touch is arranged in an array of air vents.

[0006] By adopting the above technical solution, firstly, during the process of the catheter being cut and transported onto the conveyor belt, the air inlet solenoid valve is kept closed to avoid affecting the transport of the catheter. Then, when the catheter is in place, the air inlet solenoid valve opens, and high-pressure airflow is ejected from multiple air holes in the air blowing pipe, causing the catheter to be blown towards the buffer blocking mechanism. After the catheter hits the buffer blocking mechanism, it falls onto the machine table. This process is repeated until the catheter is neatly hung on the machine table. Finally, by blowing air onto the side of the catheter, the discharge direction of the catheter is made perpendicular to the transport direction during catheter processing. The machine table is also set up to temporarily store the blown-down catheters for easy collection by workers. At the same time, the vent holes on the baffle groove can prevent the airflow on the air blowing pipe from knocking over the baffle groove and causing a rebound.

[0007] A further feature of this invention is that a discharge plate is rotatably connected to the side of the machine base away from the conveyor belt, the side of the discharge plate near the conveyor belt is tilted upwards, and an electric push rod is hinged between the bottom of the machine base and the discharge plate. When the discharge plate is in its initial state, the upper surface of the discharge plate tilts downwards toward the direction close to the conveyor belt.

[0008] By adopting the above technical solution, when the unloading plate is in the initial state, the upper surface of the unloading plate extends downward towards the direction close to the conveyor belt, and the side of the unloading plate close to the conveyor belt tilts upward, thereby collecting the catheters and preventing them from slipping. At the same time, during unloading, if a collection box is set on one side of the machine, the unloading plate can be rotated upward by an electric push rod, so that the accumulated catheters fall into the collection box. Since the direction in which the catheters fall into the collection box is perpendicular to the length direction of the catheters, the catheters falling into the collection box are very neat.

[0009] A further feature of this invention is that: a rotating seat is provided on the first bracket, both ends of the air blowing pipe are rotatably connected to the rotating seat, and an adjustment mechanism for adjusting the angle of the air blowing pipe is provided between the air blowing pipe and the rotating seat.

[0010] By adopting the above technical solution, the angle of the air blowing tube can be adjusted through the adjustment mechanism, thereby adjusting the angle of the air blowing hole on the air blowing tube to adjust the airflow blowing effect on the catheter.

[0011] A further feature of this invention is that the adjusting mechanism includes an arc-shaped block disposed at the end of the air blowing pipe and having multiple limit holes arranged in an arc array, and a limit knob bolt threaded onto the rotating seat and used to be embedded in any one of the limit holes.

[0012] By adopting the above technical solution, after adjusting the angle of the air outlet pipe, one end of the limiting knob bolt is embedded in the corresponding limiting hole after adjustment, thereby fixing the angle of the air outlet pipe.

[0013] A further feature of this invention is that an upwardly extending partition is provided on the side of the machine tool near the conveyor belt.

[0014] By adopting the above technical solution and setting up a partition, the gap between the side of the conveyor belt and the machine is eliminated, thereby preventing the catheter from falling off. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example: An air-blowing feeding device for a catheter extrusion production line, such as... Figure 1 and Figure 2 As shown, it includes a conveyor belt 1 for receiving the cut catheter, an air-blowing feeding mechanism located behind the conveyor belt 1, a machine platform 3 located in front of the conveyor belt 1, and a buffer blocking mechanism located in front of the conveyor belt 1 to prevent the catheter from flying out during the process of being blown down onto the machine platform 3.

[0020] like Figure 1 and Figure 2 As shown, the air blowing feeding mechanism includes two first supports 21 mounted on the frame of the conveyor belt 1, an air blowing pipe 22 mounted between the first supports 21 and along the length of the conveyor belt 1, an air inlet pipe 23 connected to the air blowing pipe 22 and connected to an external compressed air source, and an air inlet solenoid valve 24 located in the middle of the air inlet pipe 23. The periphery of the air blowing pipe 22 is provided with a plurality of air blowing holes 221 arranged in an array along its length and inclined toward the upper surface of the conveyor belt 1.

[0021] like Figure 1 and Figure 2As shown, a rotating seat 25 is provided on the first bracket 21, and both ends of the air blowing pipe 22 are rotatably connected to the rotating seat 25. An adjustment mechanism for adjusting the angle of the air blowing pipe 22 is provided between the air blowing pipe 22 and the rotating seat 25. The adjustment mechanism includes an arc-shaped block 51 provided at the end of the air blowing pipe 22 and having multiple limit holes 511 arranged in an arc shape, and a limit knob bolt 52 threadedly connected to the rotating seat 25 and used to be embedded in any one of the limit holes 511.

[0022] like Figure 1 As shown, the buffer blocking mechanism includes two second supports 41 disposed on the front side of the conveyor belt 1 and a baffle groove 42 disposed between the two second supports 41 and in the shape of a hollow shell. The end of the baffle groove 42 near the conveyor belt 1 is located above the conveyor belt 1 and the end near the machine base 3 is inclined downward. The end face of the baffle groove 42 near the conveyor belt 1 and for the catheter to touch is provided with an array of ventilation holes 421.

[0023] like Figure 1 As shown, a discharge plate 32 is rotatably connected to the side of the machine base 3 away from the conveyor belt 1. The side of the discharge plate 32 closest to the conveyor belt 1 is tilted upwards. An electric push rod 33 is hinged between the bottom of the machine base 3 and the discharge plate 32. When the discharge plate 32 is in its initial state, the upper surface of the discharge plate 32 tilts downwards towards the direction close to the conveyor belt 1. At the same time, an upwardly extending partition 31 is provided on the side of the machine base 3 closest to the conveyor belt 1.

[0024] Implementation effect: First, during the process of the catheter being cut and transported to the conveyor belt 1, the air intake solenoid valve 24 is kept closed to avoid affecting the transport of the catheter. Then, when the catheter is in place, the air intake solenoid valve 24 opens, and high-pressure airflow is ejected from multiple air holes 221 of the air blowing pipe 22, causing the catheter to be blown towards the buffer blocking mechanism. After the catheter hits the buffer blocking mechanism, it falls onto the machine platform 3. This process is repeated until the catheter is neatly hung on the machine platform 3. Finally, by blowing air onto the side of the catheter, the discharge direction of the catheter is made perpendicular to the transport direction during catheter processing. The machine platform 3 is set up to temporarily store the blown-down catheters for easy collection by workers. At the same time, the vent holes 421 on the baffle groove 42 can prevent the airflow on the air blowing pipe 22 from blowing down the baffle groove 42 and causing a rebound.

[0025] When the unloading plate 32 is in its initial state, the upper surface of the unloading plate 32 extends downwards towards the direction close to the conveyor belt 1, and the side of the unloading plate 32 close to the conveyor belt 1 tilts upwards, thereby collecting the catheters and preventing them from slipping. At the same time, during unloading, if a collection box is set on one side of the machine 3, the unloading plate 32 can be rotated upwards by the electric push rod 33, so that the accumulated catheters fall into the collection box. Since the direction in which the catheters fall into the collection box is perpendicular to the length direction of the catheters, the catheters falling into the collection box are very neat.

[0026] The angle of the air blowing tube 22 can be adjusted by the adjustment mechanism, thereby adjusting the angle of the air blowing hole 221 on the air blowing tube 22 to regulate the airflow effect on the catheter. After adjusting the angle of the air blowing tube, one end of the limiting knob bolt 52 is inserted into the corresponding limiting hole 511 after adjustment, thereby fixing the angle of the air blowing tube 22. By setting the partition 31, the gap between the side of the conveyor belt 1 and the machine base 3 is eliminated, thereby preventing the catheter from falling off.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
