Description

Technical Field

[0001] The utility model belongs to the technical field of lead-free tin bar production, in particular to an automatic metering device for lead-free tin bar production. Background Art

[0002] Lead-free tin bar is a welding material used for electronic welding. It is composed of lead-free materials and tin, and is mainly used in lead-free welding processes. Due to environmental protection and health considerations, lead-free welding materials have gradually replaced lead-containing welding materials and become the mainstream. Lead-free tin bars have excellent welding performance and environmental protection, and are widely used in electronics, communications, instrumentation, and household appliances. During the production of tin bars, liquid tin needs to be poured into the mold using a collection bucket for cooling and shaping.

[0003] The existing automatic metering device for lead-free tin bar production is a metal portable bucket with quantitative marks inside. The operator can carry the portable bucket and scoop a bucket of tin liquid that reaches the mark inside the heating barrel to achieve the quantitative effect, and then pour it into the mold for cooling and molding. However, this quantitative metering method can easily cause the tin liquid to exceed the marked point, resulting in unclear marked points and inaccurate subsequent use after multiple measurements. Utility Model Content

[0004] In order to solve the problem in the prior art that the tin liquid exceeds the marking point, resulting in unclear marking points and inaccurate subsequent use due to multiple measurements, the utility model provides an automatic metering device for lead-free tin bar production. By pulling the plate and the sliding block between the positioning rails, the liquid tin is allowed to enter the collection barrel along the discharge hole and the flow hole. When the measured weight is reached, the flow hole seals the discharge hole, which solves the problem of unclear marking of the quantitative position caused by manual collection in the past, and improves the effect of quantitative measurement.

[0005] To achieve the above purpose, the specific technical solution is as follows:

[0006] An automatic metering device for lead-free tin bar production, comprising a heating barrel, a discharge hole is provided at the bottom of the heating barrel, a pulling plate is slidably connected to the bottom of the heating barrel near the discharge hole, a flow hole is provided at the pulling plate near the discharge hole, a collecting barrel is arranged below the flow hole, a handle is fixedly connected to the outside of the collecting barrel, and a pouring port is fixedly connected to the side of the collecting barrel away from the handle;

[0007] The pouring port is connected to the collecting bucket, the inner side of the collecting bucket is rounded near the top, a discharge pipe is provided inside the collecting bucket near the top, the discharge pipe is fixedly connected to the bottom of the pulling plate, and the discharge pipe is rounded near one end of the collecting bucket.

[0008] Furthermore, a positioning rail is fixedly connected to the bottom of the heating barrel, and there are two groups of positioning rails symmetrically arranged. A sliding block is slidably connected inside the positioning rail, and a pulling plate is fixedly connected to the side of the sliding block away from the positioning rail.

[0009] Furthermore, the sliding block is fixedly connected to a position of the pulling plate away from the collecting barrel, the pulling plate is arranged in an "L" shape, and a temperature insulation component is arranged outside the collecting barrel.

[0010] Furthermore, the thermal insulation component includes a thermal insulation pad, which is fixedly connected to the bottom of the heating barrel. A placement groove is provided on one side of the thermal insulation pad, and the pulling plate is arranged inside the placement groove.

[0011] Furthermore, a lifting plate is abutted against the bottom of the collecting barrel, and a weight-reducing spring is fixedly connected to the bottom of the lifting plate. There are two groups of weight-reducing springs that are symmetrically arranged.

[0012] Furthermore, a positioning pad is fixedly connected to the bottom of the weight-reducing spring, a supporting leg is fixedly connected inside the positioning pad, and the supporting leg is fixedly connected to the bottom of the heating barrel.

[0013] Furthermore, a limiting rod is fixedly connected to one side of the positioning pad opposite to the heat insulation pad, and the limiting rod is slidably connected to the inside of the lifting plate. There are two groups of limiting rods that are symmetrically arranged.

[0014] Compared with the prior art, the beneficial effects of the present invention are at least:

[0015] (1) By moving the pulling plate, the pulling plate is allowed to slide inside the positioning rail by means of the sliding block, so that the pulling plate blocks the connection between the discharge hole and the flow hole. At this time, the collecting bucket can be removed from under the pulling plate, thereby achieving the effect of quantitative removal. This solves the problem of the tin liquid adhering to the quantitative mark and making it inconvenient to perform quantitative statistics in the previous manual scooping method, thereby improving the effect of quantitative weighing.

[0016] (2) The collecting bucket is placed on the top of the lifting plate. At this time, the weight-reducing spring exerts a certain thrust on the lifting plate, thereby helping the operator to share the weight of the collecting bucket. When the lifting plate is full, the collecting bucket will be slowly pulled out, solving the problem of the previous hand-carrying method, which causes the weight of the tin liquid to put a heavy burden on the operator's wrist and makes it inconvenient to take it, thereby improving the convenience of taking the collecting bucket.

DETAILED DESCRIPTION

[0023] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0024] like Figure 1 and Figure 5As shown, the utility model aims to provide a non-destructive testing device that can non-invasively detect the weight, composition and concentration of electronic cigarette oil, so as to solve the problem in the prior art that the tin liquid exceeds the marking point, resulting in unclear marking points and inaccurate subsequent use due to multiple measurements. According to the above functions, the entire device includes a heating barrel 1, which is characterized in that: a discharge hole 2 is provided at the bottom of the heating barrel 1, a pulling plate 3 is slidably connected to the bottom of the heating barrel 1 near the discharge hole 2, a flow hole 4 is provided at the pulling plate 3 near the discharge hole 2, a collecting barrel 7 is provided below the flow hole 4, a handle 8 is fixedly connected to the outside of the collecting barrel 7, and a pouring port 9 is fixedly connected to the side of the collecting barrel 7 away from the handle 8; the pouring port 9 is connected to the collecting barrel 7, the inner side of the collecting barrel 7 is rounded near the top, and a feeding pipe 10 is provided inside the collecting barrel 7 near the top. The feeding pipe 10 is fixedly connected to the bottom of the pulling plate 3, and the feeding pipe 10 is rounded at one end near the collecting barrel 7. In this embodiment, when in use, the non-destructive When the lead-tin raw material melts, the liquid tin will flow into the collecting barrel 7 along the flow hole 4. At this time, the collecting barrel 7 needs to be taken out. The operator can hold his hand on the outside of the handle 8 and move the pulling plate 3 to drive the feeding pipe 10 and the collecting barrel 7 to move out from the bottom of the heating barrel 1. At this time, the collecting barrel 7 can be taken out from the outside of the pouring port 9, so that the liquid tin can be poured out from the pouring port 9 for molding. When it is necessary to pour the tin liquid again, the collecting barrel 7 is put on the outside of the feeding pipe 10, and the rounded corner structure can ensure that the connection between the collecting barrel 7 and the feeding pipe 10 is more convenient. At this time, the collecting barrel 7 and the pulling plate 3 are pushed under the heating barrel 1 together, so that the liquid tin can continue to be poured into the collecting barrel 7. In this way, the liquid tin can be quantitatively measured.

[0025] like Figure 5 As shown, a positioning rail 6 is fixedly connected to the bottom of the heating barrel 1. There are two groups of positioning rails 6 that are symmetrically arranged. A sliding block 5 is slidably connected inside the positioning rail 6. A pulling plate 3 is fixedly connected to the side of the sliding block 5 away from the positioning rail 6. In this embodiment, when sealing, the pulling plate 3 slides inside the positioning rail 6 by relying on the sliding block 5, which can ensure that the pulling plate 3 runs more smoothly at the bottom of the heating barrel 1, thereby achieving a smooth opening and closing and sealing effect, thereby realizing the subsequent processing of liquid tin by opening and closing the discharge hole 2.

[0026] like Figure 2 and Figure 5As shown, the sliding block 5 is fixedly connected to the pulling plate 3 away from the collecting barrel 7, the pulling plate 3 is arranged in an "L" shape, and an insulation component is arranged outside the collecting barrel 7. The insulation component includes an insulation pad 11, and the insulation pad 11 is fixedly connected to the bottom of the heating barrel 1. A placement groove 12 is opened on one side of the insulation pad 11, and the pulling plate 3 is arranged inside the placement groove 12. In this embodiment, the structure of the pulling plate 3 can achieve the effect of convenient movement of the pulling plate 3, and the bending part of the pulling plate 3 also has a certain insulation effect. When in use, the insulation pad 11 can also isolate the liquid tin taken out from the collecting barrel 7 to avoid the risk of scalding to the operator. Moreover, the pulling plate 3 and the collecting barrel 7 are both arranged inside the insulation pad 11, which also ensures that the liquid tin will not drip near the equipment, causing pollution problems at the operation site, thereby improving the neatness of the equipment.

[0027] like Figure 3 and Figure 4 As shown, a lifting plate 13 is abutted against the bottom of the collecting bucket 7, and a weight-reducing spring 14 is fixedly connected to the bottom of the lifting plate 13. There are two groups of weight-reducing springs 14 that are symmetrically arranged. In this embodiment, the weight of the collecting bucket 7 on the top of the lifting plate 13 can be reduced by the weight-reducing spring 14, so as to avoid the problem that the operator cannot pull the collecting bucket 7 by the handle 8 when there is enough tin liquid in the collecting bucket 7, thereby improving the convenience during use.

[0028] like Figure 1 and Figure 3 As shown, a positioning pad 16 is fixedly connected to the bottom of the weight-reducing spring 14, and a supporting leg 17 is fixedly connected inside the positioning pad 16. The supporting leg 17 is fixedly connected to the bottom of the heating barrel 1, and a limiting rod 15 is fixedly connected to the side opposite to the positioning pad 16 and the thermal insulation pad 11. The limiting rod 15 is slidably connected inside the lifting plate 13. There are two groups of limiting rods 15 that are symmetrically arranged. In this embodiment, the positioning pad 16 can be fixed by the supporting legs 17, and the heating barrel 1 and the thermal insulation pad 11 can also be supported. The positioning pad 16 is fixed by the supporting legs 17, and the sliding position of the lifting plate 13 can be limited by the limiting rod 15 at the top of the positioning pad 16, and the operating position of the lifting plate 13 is ensured, so that the weight-reducing spring 14 can push the lifting plate 13 to reset to the position near the bottom inside the placement slot 12, thereby achieving the effect of sharing the weight.
