Description

Technical Field

[0001] This utility model relates to the field of bottle cap processing technology, and more specifically, to an automatic bottle cap feeding mechanism and a polishing machine. Background Technology

[0002] During the production process, some bottle caps are coated with varnish using a varnishing machine. This involves applying varnish to the top of the bottle cap and then curing it using an LED light source, which significantly improves the gloss, abrasion resistance, and other properties of the bottle cap.

[0003] There are two main methods of applying oil: spraying and roller coating. Most existing automatic feeding mechanisms can only arrange bottle caps in an orderly manner on the conveyor line. Since the bottle caps are not fixed, this feeding method is mainly suitable for spraying. For roller coating (where the bottle caps are usually fixed), there is currently no dedicated automatic feeding mechanism, and manual feeding is mostly used, which is inefficient. Utility Model Content

[0004] The purpose of this invention is to provide an automatic bottle cap feeding mechanism and a polishing machine to solve the above-mentioned defects of the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic bottle cap feeding mechanism includes a feeding device and further includes:

[0007] Conveyor line;

[0008] Several tooling plates that can move with the conveyor line, each tooling plate being equipped with support columns; and

[0009] The discharge guide rail located above the conveyor line is used to receive bottle caps from the feeding equipment. The discharge guide rail gradually decreases along the conveying direction of the conveyor line. Elastic support components are provided on both sides of the discharge port of the discharge guide rail to restrict the bottle caps from sliding out of the discharge port. When the support column passes through the discharge port and pushes the bottle cap, the elastic support components can open outward so that the bottle cap can slide out of the discharge port and fit on the support column.

[0010] Optionally, a guide spring is provided above the discharge port. The upper end of the guide spring is fixedly connected to the discharge guide rail. Along the direction from the upper end to the lower end of the guide spring, the distance between the guide spring and the top of the support column gradually decreases, so that the bottle cap is gradually pressed downward after being put on the support column.

[0011] Optionally, the elastic support component includes a connecting arm, a spring, and a limiting roller for contacting the bottle cap. The middle part of the connecting arm is rotatably connected to the bottom of the discharge guide rail. The limiting roller is rotatably disposed at one end of the connecting arm, and the spring is disposed between the other end of the connecting arm and the side of the discharge guide rail, so that the limiting roller maintains the tendency to turn towards the middle of the discharge port, thereby restricting the bottle cap from sliding out of the discharge port.

[0012] Optionally, the connecting arm is provided with a limiting member between its rotation point and the limiting roller. The limiting member abuts against the side of the discharge guide rail to limit the angle at which the limiting roller rotates toward the center of the discharge port.

[0013] Optionally, the tooling plate is provided with a plurality of support columns along the width direction of the conveyor line, and the number of the discharge guide rails is the same as the number of support columns along the width direction of the conveyor line.

[0014] Optionally, all the support columns in the width direction of the conveyor line are defined as a group of support components, and multiple groups of support components are provided on the tooling plate along the conveying direction of the conveyor line.

[0015] Optionally, the conveyor line includes a conveyor belt, a conveyor rail, and a connecting seat. The conveyor rail and the conveyor belt are arranged side by side. The number of connecting seats corresponds one-to-one with the number of tooling plates. The tooling plates are fixedly connected to the connecting seats. The connecting seats are slidably arranged on the conveyor rail and fixedly connected to the conveyor belt.

[0016] This utility model also provides a varnishing machine, including the automatic bottle cap feeding mechanism described in any one of the above.

[0017] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, the bottle caps from the feeding device are arranged one by one at the discharge guide rail and temporarily blocked by the elastic support component. When the tooling plate moves with the conveyor line, and the support column passes the discharge port of the discharge guide rail, due to the inclined arrangement of the discharge guide rail, the support column will contact the bottle cap opening and push the bottle cap, causing the elastic support component to open outward. After the bottle cap slides out of the discharge port, it will be fitted onto the support column, thereby fixing the bottle cap and facilitating subsequent oiling of the bottle cap top by the rubber roller. It can be seen that this utility model realizes automatic feeding of bottle caps by the rubber roller oiling method, which improves efficiency. Attached Figure Description

Detailed Implementation

[0023] Example 1

[0024] refer to Figure 1 An automatic bottle cap feeding mechanism includes a feeding device (not shown), a conveyor line 1, a tooling plate 2, and a discharge guide rail 4.

[0025] As an option, refer to Figure 2 In this embodiment, the conveyor line 1 includes a conveyor belt 101, a conveyor rail 102, and a connecting seat 103. The conveyor rail 102 and the conveyor belt 101 are arranged side by side. The number of connecting seats 103 corresponds one-to-one with the number of tooling plates 2. The tooling plates 2 are fixedly connected to the connecting seats 103 to move with the conveyor line 1. The connecting seats 103 are slidably disposed on the conveyor rail 102 and fixedly connected to the conveyor belt 101. Specifically, the bottom of the connecting seat 103 is provided with two sets of pulleys, which cooperate with the conveyor rail 102. The conveyor belt 101 is driven by a driving element (such as a motor), and the conveyor rail 102 serves as a guide for the movement of the connecting seat 103. It should be noted that only a part of the conveyor line 1 is shown in the attached drawings. In actual applications, the conveyor line 1 can be a circular conveyor line 1 (i.e., both the conveyor belt 101 and the conveyor rail 102 are circular), which facilitates the recycling of the tooling plates 2. Figure 1 The direction from right to left is the conveying direction. In other embodiments, the conveyor line 1 can of course be any other form that enables the conveying of the tooling plate 2.

[0026] Each tooling plate 2 is equipped with a support column 3. Alternatively, in this embodiment, two support columns 3 are provided on the tooling plate 2 along the width direction of the conveyor line 1, and two corresponding parallel discharge guide rails 4 are also provided. All support columns 3 along the width direction of the conveyor line 1 are defined as a group of support components. In this embodiment, two groups of support components are provided on the tooling plate 2 along the conveying direction of the conveyor line 1, meaning each tooling plate 2 has four support columns 3. Of course, in other embodiments, the number of support columns 3 on the tooling plate 2 along the width direction of the conveyor line 1, as well as the number of groups of support components along the width direction of the conveyor line 1, can be set according to actual needs.

[0027] The discharge guide rail 4 is located above the conveyor line 1 and is used to receive bottle caps 8 from the feeding equipment. The feeding equipment sorts the bottle caps 8 and arranges them on the discharge guide rail 4 with the top facing upwards and the opening facing downwards. The feeding equipment can be a roller sorter, a vibrating plate, etc. With two discharge guide rails 4 arranged side by side, a connecting guide rail 7 can be installed between the discharge guide rail 4 and the feeding equipment. The connecting guide rail 7 has a Y-shaped structure to divide the bottle caps 8 into two paths and deliver them to the two discharge guide rails 4 respectively. Furthermore, it is easy to understand that the discharge guide rail 4 and the connecting guide rail 7 are generally trough-shaped, meaning they have support at the bottom and baffles on both sides.

[0028] refer to Figure 1 and Figure 4 The discharge guide rail 4 is arranged at an angle, and elastic support components 5 are provided on both sides of the discharge port of the discharge guide rail 4 to restrict the bottle cap 8 from sliding out of the discharge port. The purpose of the inclined arrangement of the discharge guide rail 4 is to make the bottle cap 8 located at the discharge port tilted (that is, the discharge guide rail 4 gradually decreases along the conveying direction). In this way, one side of the bottle mouth at the bottom of the bottle cap 8 (the side located behind in the conveying direction) is higher and the other side (the side located in the front in the conveying direction) is lower. When the support column 3 passes through the discharge port, the support column 3 contacts the lower side of the bottle mouth and exerts a pushing force on the bottle cap 8. The bottle cap 8 squeezes the elastic support component 5 to open outward. Then the bottle cap 8 slides out of the discharge port and is fitted onto the support column 3. That is, this utility model achieves the fixation of the bottle cap 8 by fitting the bottle cap 8 onto the support column 3, which facilitates the subsequent oiling of the top of the bottle cap 8 by means of a rubber roller, and also realizes automatic feeding, improving efficiency.

[0029] As an alternative, in this embodiment, the elastic support component 5 includes a connecting arm 501, a spring 502, and a limiting roller 503 for contacting the bottle cap 8. The middle part of the connecting arm 501 is rotatably connected to the bottom of the discharge guide rail 4. The limiting roller 503 is rotatably disposed at one end of the connecting arm 501. The spring 502 is disposed between the other end of the connecting arm 501 and the side of the discharge guide rail 4. The arrangement of the spring 502 is not limited. For example, a blind hole is provided on the connecting arm 501, and the spring 502 is installed in the blind hole. One end of the spring 502 abuts against the bottom of the blind hole, and the other end abuts against the side of the discharge guide rail 4. Alternatively, one end of the spring 502 is fixedly connected to the side of the discharge guide rail 4, and the other end is fixedly connected to the connecting arm 501.

[0030] Under the elastic force of spring 502, the end of connecting arm 501 away from spring 502 tends to rotate towards the center of the discharge port, that is, the limiting roller 503 tends to rotate towards the center of the discharge port, restricting the bottle cap 8 from sliding out of the discharge port. When the bottle cap 8 is pushed by the support column 3, the two limiting rollers 503 open (i.e. rotate outward), allowing the bottle cap 8 to slide out of the discharge port. In practical applications, the elastic support component 5 between adjacent discharge guide rails 4 can be set in the vertical direction to save space.

[0031] Furthermore, the connecting arm 501 is provided with a limiting member 504 between its rotation point and the limiting roller 503. The limiting member 504 abuts against the side of the discharge guide rail 4 to limit the angle at which the limiting roller 503 rotates toward the center of the discharge port, preventing the limiting roller 503 from getting too close to the center of the discharge port and making it difficult to open outward, thus ensuring that the bottle cap 8 can be smoothly dislodged from the discharge port. In practical applications, the limiting member 504 can be directly replaced by a screw.

[0032] In this embodiment, a guide spring 6 is provided above the discharge port. The guide spring 6 can be a thin metal sheet with a certain degree of elasticity. It is easy to understand that each discharge guide rail 4 corresponds to one guide spring 6. The upper end of the guide spring 6 is fixedly connected to the discharge guide rail 4. Along the direction from the upper end to the lower end of the guide spring 6, the distance between the guide spring 6 and the top of the support column 3 gradually decreases. This arrangement ensures that after the bottle cap 8 is pushed out of the discharge port by the support column 3 and fitted onto the support column 3, under the action of the guide spring 6, the bottle cap 8 is gradually pressed downward, that is, the bottle cap 8 is made to fall to the bottom as much as possible (that is, the inner top surface of the bottle cap 8 contacts the top surface of the support column 3).
