Description

Technical Field

[0001] This utility model belongs to the field of parts arrangement technology, and in particular relates to a valve oil seal arrangement device. Background Technology

[0002] To automate the packaging of valve stem seals, existing technologies typically utilize vibratory feeders to arrange and convey the valve stem seals, ensuring they are transported to the packaging station in a uniform posture. During operation, the vibratory feeder employs a screening structure on its spiral track to remove valve stem seals with incorrect postures for rearrangement. Only a small percentage of valve stem seals meeting the posture requirements are successfully output from the spiral track, resulting in a low number of correctly positioned valve stem seals output per unit time, thus impacting packaging efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a valve stem seal arrangement device with higher arrangement efficiency.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed: A valve stem seal arranging device includes: a plate, a hopper, and an arranging tube.

[0005] The plate is inclined, and a strip groove is opened on its top surface. The length direction of the strip groove is consistent with the inclination direction of the plate. The lower end of the strip groove is connected to a circular tube extending to the outside of the plate for the passage of valve oil seal. The depth and width of the strip groove are greater than or equal to the radius of the valve oil seal and less than the diameter of the valve oil seal. The hoppers are spaced apart on the top of the plate. The distance between the bottom of the hopper and the bottom of the strip groove is greater than the outer diameter of the valve oil seal. The hoppers are moved back and forth along the line connecting the two sides of the plate. The valve stem is vertically arranged, and the end of the round tube is connected to the valve stem. A stop bar is provided on the side of the valve stem opposite to the round tube. Its length direction is parallel to the axis of the round tube. The front end of the stop bar extends into the interior of the valve stem. The distance between the lower edge of the connection between the valve stem and the round tube and the front end of the stop bar is greater than the outer diameter of the valve oil seal.

[0006] The beneficial effects of this utility model are as follows: This solution can push the valve oil seals to fall automatically into the strip groove through the reciprocating hopper, and use the strip groove to automatically send the valve oil seals that have fallen into it into the arranging tube. The valve oil seals are adjusted by the baffle inside the arranging tube, so that all the valve oil seals entering the arranging tube are discharged from the bottom of the arranging tube in a uniform posture, which has higher arranging efficiency and reduces the impact on the packaging progress.

[0020] like Figures 1 to 4 As shown, a valve stem seal arranging device includes: a plate 1, a hopper 2, and an arranging tube 3.

[0021] Specifically, such as Figures 1 to 3 As shown, the plate 1 is inclined, and a strip groove 11 is provided on its top surface. The length direction of the strip groove 11 is consistent with the inclination direction of the plate 1. The lower end of the strip groove 11 is connected to a circular tube 12 extending to the outside of the plate 1 for the passage of the valve oil seal. The depth and width of the strip groove 11 are greater than or equal to the radius of the valve oil seal and less than the diameter of the valve oil seal.

[0022] Specifically, such as Figure 1 As shown, the hoppers 2 are arranged at intervals above the plate 1. The distance between the bottom surface of the hopper 2 and the bottom surface of the strip groove 11 is greater than the outer diameter of the valve oil seal. The hoppers 2 are moved back and forth along the line connecting the two sides of the plate 1. Specifically, the top surface of the plate 1 is provided with a support rail 14, and the hoppers 2 are slidably arranged on the support rail 14.

[0023] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the arrangement tube 3 is vertically arranged, and the end of the round tube 12 is connected to the arrangement tube 3. A stop rod 4 is provided on the side of the arrangement tube 3 opposite to the round tube 12. Its length direction is parallel to the axis of the round tube 12. The front end of the stop rod 4 extends into the interior of the arrangement tube 3. The distance between the lower edge of the connection between the arrangement tube 3 and the round tube 12 and the front end of the stop rod 4 is greater than the outer diameter of the valve oil seal.

[0024] For ease of description, in this embodiment, the end of the valve stem seal with the rubber ring is defined as the head, and the end with the metal housing is defined as the tail. The inner diameter of the valve stem seal head is smaller than the inner diameter of the tail.

[0025] During operation, the valve oil seals stored inside the hopper 2 are first moved by the reciprocating movement of the hopper 2, so that the valve oil seals can smoothly enter the strip groove 11 and increase the probability of the valve oil seals entering the strip groove 11. After falling into the strip groove 11, the valve oil seals will move towards the lower end of the strip groove 11 and enter the round tube 12. After falling into the strip groove 11, the valve oil seals will mostly be in two postures: one is with the head facing the end of the round tube 12, and the other is with the tail facing the end of the round tube 12.

[0026] When the valve stem seal head is conveyed towards the end of the round tube 12 and enters the arrangement tube 3, the end face of the valve stem seal head contacts the front end of the stop bar 4, and under the blocking action of the stop bar 4, it automatically falls into the arrangement tube 3 with its head facing down.

[0027] When the tail of the valve stem seal is conveyed towards the end of the circular tube 12 and enters the arranging tube 3, the tail of the valve stem seal will be sleeved on the front end of the stop lever 4 and slide a distance towards the rear end of the stop lever 4 until the head of the valve stem seal separates from the circular tube 12. Under the weight of the head of the valve stem seal, the valve stem seal will swing around the front end of the stop lever 4, so that the head is downward and falls into the lower part of the arranging tube 3. Thus, the valve stem seals conveyed towards the end of the circular tube 12 are also output from the lower part of the arranging tube 3 with the head downward, achieving the purpose of uniform arrangement.

[0028] This solution can output all the valve stem seals that enter the strip groove 11, and use the arrangement tube 3 to adjust the posture of the valve stem seals so that the valve stem seals discharged from the arrangement tube 3 have a consistent posture. Compared with the traditional vibratory plate, this solution can ensure the continuous output of valve stem seals and improve the arrangement efficiency.

[0029] Preferably, the cross-section of the strip groove 11 is semi-circular, which allows the valve oil seals falling into the strip groove 11 to lie flat, effectively preventing the valve oil seals from standing upright in the strip groove 11, and allowing the valve oil seals to enter the round tube 12 more smoothly.

[0030] Preferred, such as Figure 1 As shown, a telescopic cylinder 5 is provided on one side of the plate 1 to drive the hopper 2 to move back and forth.

[0031] Preferred, such as Figure 2 As shown, a stepped hole 13 is provided on the top surface of the plate 1, and a strip groove 11 is provided at the bottom of the stepped hole 13. This structure can push the valve oil seals to gather in the strip groove 11 by means of the moving hopper 2, which helps the valve oil seals to enter the strip groove 11.

[0032] Preferred, such as Figure 4 As shown, the bottom of the front end of the shift lever 4 is sloped, which makes it easier to guide the valve stem seal that contacts the shift lever 4 through the head to fall.

[0033] In a further preferred embodiment, the stop bar 4 is threaded through the arrangement tube 3 to facilitate adjustment of the insertion depth of the stop bar 4.

[0034] The above description is merely a preferred embodiment of this utility model and does not represent the only possible embodiment or limit the scope of this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
