Description

Technical Field

[0001] The utility model relates to the technical field of valve core production, and more specifically to a valve core feeding device. Background Art

[0002] Plastic ball valves have the advantages of simple structure, flexible operation, good sealing performance, etc., and are widely used in many industries. Plastic ball valves are generally produced by injection molding. The valve core is first produced, and then the valve body is produced by secondary injection molding outside the valve core, and then the handle is assembled to complete the production. Before the secondary injection molding of the valve body, the valve core needs to go through multiple processes, and most of the existing valve core processing processes are manually processed, with low processing efficiency and cannot meet large-scale production. Some processes can be processed by automated equipment, but there is a lack of feeding devices that can neatly and continuously provide valve cores. Manual feeding of automated equipment is also prone to discontinuous, untimely, and uneven feeding. Manual feeding also consumes manpower and workers are prone to fatigue. Utility Model Content

[0003] The utility model overcomes the lack of a feeding device that can neatly and continuously provide valve cores in the above-mentioned prior art, and provides a valve core feeding device, which realizes automatic feeding of valve cores and arranges the valve cores neatly during the feeding process, thereby meeting the automated production requirements of valve cores.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a valve core feeding device, comprising: a bracket, a hopper connected to the bracket and used for placing the valve core, a conveying assembly connected to the hopper, a feeding assembly connected to the conveying assembly and a receiving plate connected to the feeding assembly; the feeding assembly comprises a feeder connected to the bracket and a screening trough installed on the feeder; the screening trough comprises a connecting section connected to the conveying assembly, a screening section connected to the connecting section and a feeding section connected to the screening section; a drop-out port is provided on the side of the screening section, a guide portion is provided on the side of the drop-out port close to the feeding section, a first side plate for limiting the rotation of the valve core is provided on both sides of the feeding section and an open groove is provided on the bottom, the receiving plate is located below the drop-out port, and the guide portion is used to guide the valve core to rotate and arrange it neatly.

[0005] The valve core is placed in the hopper and transported to the feeding component by the conveying component. Under the action of the feeding component, the feeding is carried out in an orderly and automatic manner. The feeding component includes a feeder and a screening trough. The feeder is a feeder with a vibration function. A linear vibrator is preferably used. When a linear vibrator is used, the screening trough can be set horizontally. When other ordinary vibrators are used, the screening trough needs to be set slightly tilted. The function of the screening trough is to screen the valve core. The valve core falls onto the connecting section of the screening trough through the conveying component, and then the valve core moves to the screening section under the vibration of the feeder. The valve core includes a valve ball with a through hole and a valve stem connected to the ball. A drop port is provided on the side of the screening section. When the valve core moves to the screening section, if the valve ball and the valve stem of the valve core are both located on the working surface of the screening section, the valve core will continue to move to the feeding section. If the valve ball or the valve stem of the valve core extends out of the drop port, the valve core falls from the drop port under the vibration of the feeder and falls onto the receiving plate, waiting to be collected and then put into the hopper again.

[0006] The two side surfaces of the valve ball at both ends of the through hole are recorded as valve core side surfaces, and the distance between the valve core side surfaces on both sides is less than the diameter of the valve ball. A guide portion is provided on the side of the drop opening close to the feeding section. Specifically, the top surface of the guide portion is an inclined surface, and the height of one end of the guide portion close to the screening section is consistent with the height of the working surface of the screening section. For the valve core moved to the feeding section, during the movement, the side surface of the valve core contacts the guide portion. During the movement, under the action of the guide portion and the vibration of the feeder, the side surface of the valve core slowly stands up until the valve core completely enters the feeding section. The provision of the guide portion can prevent the valve core from being stuck between the screening section and the feeding section. After the valve core enters the feeding section, the side surface of the valve core contacts the inner side surface of the first side plate, and is neatly arranged under the action of the restricted rotation of the first side plate. Then the valve stem portion gradually approaches the opening groove, and the valve stem falls from the opening groove during the movement, thereby straightening the valve core, so that the valve core is fed neatly and orderly when the valve stem is facing downward, thereby realizing automatic feeding, improving the efficiency of manual material collection, and meeting the large-scale production needs of valve cores, and also meeting the needs of automated production. Furthermore, a first cover plate is connected to the top of the first side plate away from the guide portion. The height of the first cover plate is greater than the diameter of the valve ball, and its vertical projection covers the opening groove.

[0007] Preferably, the conveying assembly includes a conveyor belt assembly connected to the bracket and a driving unit connected to the conveyor belt assembly; one end of the conveyor belt assembly is connected to the hopper, and the other end is connected to the connecting section.

[0008] The valve core falls from the discharge port of the hopper onto the conveyor belt assembly. The driving unit drives the conveyor belt assembly to work, and then transmits the valve core to the connecting section. The conveyor belt in the conveyor belt assembly can be an ordinary belt conveyor belt or a conveyor belt with a baffle. At the same time, a soft conveyor belt should be selected, such as PVC, PU or rubber materials to prevent the valve core from being damaged.

[0009] Preferably, the conveyor belt assembly is arranged obliquely and one end connected to the hopper is lower than the other end, and the discharge port of the hopper is connected to the conveyor belt assembly.

[0010] The conveyor belt assembly is tilted and connected to the discharge port of the hopper, which is more conducive to the discharge of the valve core. At the same time, the discharge port of the hopper is located obliquely above the conveyor belt in the conveyor belt assembly, and both sides of the discharge port are closed and connected to the conveyor belt assembly to prevent the valve core from falling from both sides.

[0011] Preferably, the conveyor belt assembly comprises a baffle conveyor belt provided with a plurality of first baffles, and a second baffle for preventing the valve core from falling is provided at the bottom of the discharge port of the hopper, and the second baffle is a flexible baffle.

[0012] A baffle conveyor belt with a first baffle is provided to separate the valve cores during conveyance, so as to facilitate orderly feeding and prevent the valve cores from being stacked together. A second baffle is provided at the bottom of the discharge port to prevent the valve cores from falling between the two first baffles. The second baffle is a flexible baffle, and the first baffle moves the second baffle. Furthermore, the first baffle is also a flexible baffle, and the flexible baffle refers to a baffle that can be bent, such as a rubber baffle or a silicone baffle. Furthermore, in the conveyor belt assembly, third side plates for preventing the valve cores from falling are provided on both sides of the baffle conveyor belt.

[0013] Preferably, a first transition plate is connected to one end of the conveyor belt assembly close to the connecting section, and the first transition plate is higher than the connecting section and inclined toward the connecting section.

[0014] After the valve core is transported by the conveyor belt, it falls onto the connecting section. The conveyor belt assembly is connected to the first transition plate, so that the valve core first falls onto the first transition plate and then falls onto the connecting section. The first transition plate acts as a buffer. Furthermore, fourth side plates are provided on both sides of the first transition plate to prevent the valve core from falling. Furthermore, a second transition plate is provided on the side of the connecting section close to the first transition plate.

[0015] Preferably, a second side plate for preventing the valve core from falling is provided on a side of the connecting section away from the conveyor belt assembly.

[0016] The second side plate is used to block the valve core to prevent the valve core from falling out directly after falling from the conveyor belt assembly. At the same time, the height of the second side plate should be greater than the diameter of the valve ball. Furthermore, a second cover plate is connected to the top of the second side plate. The projection of the second cover plate in the vertical direction covers the working surfaces of the connecting section and the screening section, thereby fully preventing the valve core from falling.

[0017] Preferably, the screening trough is higher than the hopper, and one end of the material receiving plate away from the material feeding assembly is connected to the hopper.

[0018] The receiving plate is used to catch the valve core that falls from the material drop port. This part of the valve core needs to be put into the hopper again to continue feeding. The screening trough is set higher than the hopper, and a receiving plate is set to connect with the hopper. At this time, the receiving plate is inclined. After the valve core falls onto the receiving plate, it falls directly back into the hopper under the action of gravity.

[0019] Preferably, the working surfaces of the connecting section and the screening section are both inclined, and the side where the drop-out port is located is higher, and the working surface of the feeding section is a concave arc surface.

[0020] The working surfaces of the connecting section and the screening section are both inclined toward the direction away from the blanking port, with the side close to the blanking port higher and the other side lower. The working surface forms an acute angle with the first side plate on the side away from the blanking port, which is convenient for catching the valve core and for the valve stem to slide completely onto the working surface, thereby reducing the probability of the valve core falling from the blanking port. The working surface of the feeding section is a concave arc surface, corresponding to the spherical surface of the valve ball, which is conducive to the stable movement of the valve core.

[0021] Preferably, the conveying assembly is connected to a sensor for detecting whether there is a valve core on the screening tank.

[0022] A sensor is set up to monitor the feeding situation of the valve core on the screening tank. It is mainly used to cooperate with other automated equipment to realize automated production. If too many valve cores remain on the screening tank for a long time, it means that there is a problem in the next process, such as material jamming or shutdown. At this time, the conveying component can be temporarily shut down to stop feeding the valve core into the screening tank. Wait until the screening tank continues to feed the next process, and then open the conveying component.

[0023] Preferably, a plurality of supporting members are provided at the bottom of the bracket.

[0024] A support member is provided to ensure the stability of the bracket, and further, the support member is a foot cup with adjustable height.

The neatly arranged valve cores pass through the screening section and enter the feeding section, and then enter the next process. The entire feeding process is automatically completed by the conveying component and the feeding component, realizing automatic feeding of neatly arranged valve cores and saving manpower.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0043] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0044] Example 1

[0045] like Figure 1 As shown, a valve core feeding device comprises: a bracket 1, a hopper 2 connected to the bracket 1 and used to place the valve core, a conveying assembly 3 connected to the hopper 2, a feeding assembly connected to the conveying assembly 3, and a receiving plate 4 connected to the feeding assembly; the feeding assembly comprises a feeder 5 connected to the bracket 1 and a screening slot 6 installed on the feeder 5; Figure 7 As shown, the screening trough 6 includes a connecting section 601 connected to the conveying assembly 3, a screening section 602 connected to the connecting section 601 and a feeding section 603 connected to the screening section 602; a material drop opening 604 is provided on the side of the screening section 602, and a first side plate 605 for limiting the rotation of the valve core is provided on both sides of the feeding section 603 and an open groove 606 is provided on the bottom, and the receiving plate 4 is located below the material drop opening 604.

[0046] The valve core is placed in the hopper 2 and is transported to the feeding component by the conveying component 3. Under the action of the feeding component, the feeding is carried out in an orderly and automatic manner. The feeding component includes a feeder 5 and a screening slot 6. The feeder 5 is a feeder with a vibration function. A linear vibrator is preferably used. When a linear vibrator is used, the screening slot 6 can be set horizontally. When other ordinary vibrators are used, the screening slot 6 needs to be set slightly tilted. The function of the screening slot 6 is to screen the valve core. The valve core falls onto the connecting section 601 of the screening slot 6 through the conveying component 3, and then the valve core moves under the vibration of the feeder 5. When the valve core moves to the screening section 602, the valve core includes a valve ball 14 with a through hole and a valve stem 15 connected to the ball. A drop port 604 is provided on the side of the screening section 602. When the valve core moves to the screening section 602, if the valve ball 14 and the valve stem 15 of the valve core are both located on the working surface of the screening section 602, the valve core will continue to move to the feeding section 603. If the valve ball 14 or the valve stem 15 of the valve core extends out of the drop port 604, the valve core will fall from the drop port 604 under the vibration of the feeder 5, and fall onto the receiving plate 4, waiting to be collected and put into the hopper 2 again.

[0047] For the valve core moved to the feeding section 603, the two side surfaces of the valve ball 14 at both ends of the through hole are recorded as valve core side surfaces 16, and the distance between the valve core side surfaces 16 on both sides is smaller than the diameter of the valve ball 14. When the valve core moves to the feeding section 603, the valve core side surfaces 16 contact the inner side surfaces of the first side plate 605, and are arranged under the action of the restricted rotation of the first side plate 605. Furthermore, the first side plate 605 located on the side of the blanking port 604 is provided with a guide portion 608 at one end close to the blanking port 604, and the top surface of the guide portion 608 is an inclined surface, and the height of the end of the guide portion 608 close to the screening section 602 is consistent with the height of the working surface of the screening section 602. When the valve core passes through the guide portion 60 8, the side surface 16 of the valve core contacts the top surface of the guide portion 608. During the movement, under the action of the guide portion 608, the side surface 16 of the valve core slowly stands up until the valve core completely enters the feeding section 603. The guide portion 608 can prevent the valve core from being stuck between the screening section 602 and the feeding section 603. After the valve core completely enters the feeding section 603, the valve stem 15 gradually approaches the opening groove 606. The valve stem 15 falls from the opening groove 606 during the movement, thereby aligning the valve core, so that the valve core is fed in an orderly manner when the valve stem 15 is facing downward, thereby realizing automatic feeding, improving the efficiency of manual material collection, and meeting the large-scale production needs of valve cores, and also meeting the needs of automated production. Furthermore, the top of the first side plate 605 away from the guide portion 608 is connected to the first cover plate 10, the height of the first cover plate 10 is greater than the diameter of the valve ball 14, and the vertical projection covers the opening groove 606.

[0048] The beneficial effects of this embodiment are as follows: the conveying component 3 automatically conveys the valve core from the hopper 2 to the feeding component. In the feeding component, the feeder 5 provides a driving force to transport the valve core from the connecting section 601 of the screening slot 6 to the screening section 602. The screening section 602 is provided with a drop port 604. The unevenly arranged valve cores fall from the drop port 604 onto the receiving plate 4, and are then put back into the hopper 2 for feeding again. The neatly arranged valve cores pass through the screening section 602 and enter the feeding section 603, and then enter the next process. The entire feeding process is automatically completed by the conveying component 3 and the feeding component, realizing automatic feeding of neatly arranged valve cores and saving manpower.

[0049] Example 2

[0050] Based on Example 1, the difference from Example 1 is that:

[0051] like Figure 2 As shown, the conveying assembly 3 includes a conveyor belt assembly 301 connected to the bracket 1 and a driving unit 302 connected to the conveyor belt assembly 301; Figure 4-5 As shown, one end of the conveyor belt assembly 301 is connected to the hopper 2, and the other end is connected to the connecting section 601. The conveyor belt assembly 301 is tilted and the end connected to the hopper 2 is lower than the other end, and the discharge port of the hopper 2 is connected to the conveyor belt assembly 301. Figure 6 As shown, the conveyor belt assembly 301 includes a baffle conveyor belt 301b provided with a plurality of first baffles 301a, and a second baffle 201 for preventing the valve core from falling is provided at the bottom of the discharge port of the hopper 2, and the second baffle 201 is a flexible baffle. The end of the conveyor belt assembly 301 close to the connecting section 601 is connected with a first transition plate 7, and the first transition plate 7 is higher than the connecting section 601 and tilted toward the connecting section 601. A second side plate 607 for preventing the valve core from falling is provided on the side of the connecting section 601 away from the conveyor belt assembly 301.

[0052] The valve core falls from the discharge port of the hopper 2 onto the conveyor belt assembly 301. The driving unit 302 drives the conveyor belt assembly 301 to work, and then transfers the valve core to the connecting section 601. The conveyor belt in the conveyor belt assembly 301 can be an ordinary belt conveyor belt, or a conveyor belt with a baffle. At the same time, a conveyor belt with a soft texture should be selected, such as PVC, PU or rubber, etc., to prevent the valve core from being damaged. The conveyor belt assembly 301 is tilted and connected to the discharge port of the hopper 2, which is more conducive to the discharge of the valve core. At the same time, the discharge port of the hopper 2 is located obliquely above the conveyor belt in the conveyor belt assembly 301, and the two sides of the discharge port are closed and connected to the conveyor belt assembly 301, so that the valve core will not fall from both sides. A baffle conveyor belt 301b with a first baffle 301a is provided to separate the valve cores during conveyance, so as to facilitate orderly feeding and prevent the valve cores from being stacked together. The second baffle 201 is provided at the bottom of the discharge port to prevent the valve cores from falling between the two first baffles 301a. The second baffle 201 is a flexible baffle, and the first baffle 301a moves the second baffle 201. Further, the first baffle 301a is also a flexible baffle, which refers to a baffle that can be bent, such as a rubber baffle or a silicone baffle. Further, in the conveyor belt assembly 301, third side plates 11 for preventing the valve cores from falling are provided on both sides of the baffle conveyor belt 301b. After the valve core is conveyed by the conveyor belt, it falls onto the connecting section 601. When the conveyor belt assembly 301 is connected to the first transition plate 7, the valve core first falls onto the first transition plate 7 and then falls onto the connecting section 601. The first transition plate 7 plays a buffering role. Further, fourth side plates 12 are provided on both sides of the first transition plate 7 to prevent the valve core from falling. Further, a second transition plate 17 is provided on one side of the connecting section 601 close to the first transition plate 7. The second side plate 607 is used to block the valve core to prevent the valve core from falling directly after falling from the conveyor belt assembly 301. At the same time, the height of the second side plate 607 should be greater than the diameter of the valve ball 14. Further, the second cover plate 13 is also connected to the top of the second side plate 607. The projection of the second cover plate 13 in the vertical direction covers the working surfaces of the connecting section 601 and the screening section 602, which fully prevents the valve core from falling.

[0053] In this embodiment, the second side plate 607 is integrally provided with the first side plate 605 on the side away from the conveyor belt assembly 301 .

[0054] The remaining features and working principles of this embodiment are consistent with those of Embodiment 1.

[0055] Example 3

[0056] Based on Example 1 or Example 2, Example 1 or Example 2 is further limited, and the difference is that:

[0057] like Figure 1-2As shown, the screening tank 6 is higher than the hopper 2, and the end of the receiving plate 4 away from the feeding assembly is connected to the hopper 2. Figure 7 As shown, the working surfaces of the connecting section 601 and the screening section 602 are both inclined, and the side where the material drop opening 604 is located is higher, and the working surface of the feeding section 603 is a concave arc surface. Figure 2 As shown, the conveying assembly 3 is connected with a sensor 8 for detecting whether there is a valve core on the screening tank 6. A plurality of supporting members 9 are provided at the bottom of the bracket 1.

[0058] The receiving plate 4 is used to catch the valve core that falls from the material outlet 604. This part of the valve core needs to be put into the hopper 2 again to continue feeding. The screening slot 6 is set higher than the hopper 2, and the receiving plate 4 is connected to the hopper 2. At this time, the receiving plate 4 is inclined. After the valve core falls on the receiving plate 4, it falls directly back into the hopper 2 under the action of gravity. The working surfaces of the connecting section 601 and the screening section 602 are both inclined in the direction away from the material outlet 604. The side close to the material outlet 604 is higher and the other side is lower. The working surface forms an acute angle with the first side plate 605 on the side away from the material outlet 604, which is convenient for catching the valve core and also convenient for the valve stem 15 to completely slide onto the working surface, reducing the probability of the valve core falling from the material outlet 604. The working surface of the feeding section 603 is a concave arc surface, corresponding to the spherical surface of the valve ball 14, which is conducive to the stable movement of the valve core. The sensor 8 is used to monitor the feeding of the valve core on the screening tank 6, and is mainly used to cooperate with other automated equipment to realize automated production. If too many valve cores are retained on the screening tank 6 for a long time, it means that there is a problem in the next process, such as material jamming or shutdown, etc. At this time, the conveying component 3 can be temporarily shut down to stop feeding the valve core into the screening tank 6, and the conveying component 3 can be turned on when the screening tank 6 continues to feed the next process. The support member 9 is set to ensure the stability of the bracket 1. Further, the support member 9 is a foot cup with adjustable height.

[0059] The rest of the working principle and working process of this embodiment are consistent with those of Embodiment 1 or Embodiment 2.
