Description

Technical Field

[0001] This utility model belongs to the field of filling equipment technology, and specifically relates to a bottle mouth alignment device for a capping machine. Background Technology

[0002] In modern bottled product production lines, the capping process after filling is a crucial step. Currently, common automated capping devices typically include a bottle feeding module and a capping module. The workflow is as follows: the bottle feeding module (such as a conveyor belt, star wheel, etc.) transports the filled bottles sequentially or in groups directly below the capping module. Subsequently, the capping module drives the caps downwards, simultaneously pressing them onto the mouths of multiple bottles to complete the sealing.

[0003] However, the aforementioned existing technology has a significant drawback in practical applications. During the bottle feeding process, due to various factors such as vibration of the conveying device, instability of the bottle's center of gravity, or gaps between the bottle and the conveying guide rail, the bottle is prone to tilting, falling over, or shifting in position. When these improperly positioned bottles are sent to the capping station, their mouths cannot be precisely aligned with the caps pressed down by the capping module.

[0004] Such misalignment can lead to a series of quality problems: at best, it can cause the bottle cap to not fit tightly, resulting in substandard product sealing and potential leakage during subsequent storage and transportation; at worst, it can damage the threads of the bottle cap or the bottle mouth, causing damage to the cap and generating waste; it may even cause the bottle to be knocked over due to forcibly closing the cap, causing production line congestion or shutdown, seriously affecting production efficiency and the first-pass yield of the product.

[0005] Therefore, it is necessary to design a bottle mouth alignment device for capping machines to effectively straighten and position the bottle before the capping process, and remove the alignment device after capping to ensure the accuracy of capping. This is a key technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0006] To solve the above problems, this utility model provides a bottle mouth alignment device for a capping machine, which effectively straightens and positions the bottle before the capping process, and removes the straightening device after capping to ensure the accuracy of capping.

[0007] To achieve the above objectives, this utility model provides the following solution: A bottle mouth alignment device for a capping machine includes a support frame, a drive device mounted on the support frame, and a bottle body straightening plate mounted at the output end of the drive device. The drive device is used to drive the bottle body straightening plate to move in a vertical direction. The bottle body straightening plate has a positioning hole with a diameter larger than the outer diameter of the bottle mouth. The bottle mouth is used to pass through the positioning hole and extend out of the upper surface of the bottle body straightening plate.

[0008] Preferably, the support frame is provided with a mounting plate for fixing the drive device.

[0009] Preferably, the driving device is one of a cylinder, a hydraulic cylinder, or an electric push rod.

[0010] Preferably, the positioning holes are configured to be at least two and evenly distributed on the bottle straightening plate.

[0011] Preferably, a photoelectric sensor for detecting whether the bottle is in position is provided below the bottle straightening plate.

[0012] Preferably, an annular washer is provided on the inner wall of the positioning hole.

[0013] Preferably, the annular washer is either a silicone washer or a rubber washer.

[0014] Preferably, the output end of the driving device is connected to the bottle straightening plate via an L-shaped connecting plate.

[0015] Preferably, the positioning hole is a flared opening with the wider end facing the bottle body, and the inner diameter of the narrower end of the flared opening is larger than the outer diameter of the bottle opening.

[0016] Preferably, the bottle straightening plate is one of aluminum alloy plate, stainless steel plate or engineering plastic plate.

[0017] The present invention achieves the following technical advantages over the prior art: When the bottle feeding module delivers rows of bottles directly under the bottle straightening plate, the drive unit presses the straightening plate down, aligning the positioning holes with the bottle mouths. For some tilted bottle mouths, although the positioning holes may not be perfectly aligned, the downward press of the straightening plate will still straighten the tilted bottle mouths, thus ensuring that all bottles are upright before capping. Then, the capping device caps the bottle mouths. After capping, the straightening plate is moved up to remove the capped bottles, ensuring accurate capping without the need for manual straightening, thus achieving automation.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this invention is to provide a bottle mouth alignment device for a capping machine, which effectively straightens and positions the bottle before the capping process, and removes the alignment device after capping to ensure accurate capping.

[0022] refer to Figures 1-2 This utility model discloses a bottle mouth alignment device for a capping machine, comprising at least a support frame. A bottle body straightening plate 2 is connected to the support frame via a drive device 4. The output end of the drive device 4 is connected to the bottle body straightening plate 2, thereby driving the bottle body straightening plate 2 to move vertically. The bottle body straightening plate 2 has a positioning hole with a diameter larger than the outer diameter of the bottle mouth 6, ensuring that the bottle mouth 6 can pass through the positioning hole. After passing through the positioning hole, the bottle mouth 6 extends out of the upper surface of the bottle body straightening plate 2 to straighten the bottle body. When the bottle feeding module 1 feeds a row of bottles to the bottle body straightening plate 2... When the bottle is directly below the straightening plate 2, the driving device 4 drives the bottle straightening plate 2 to press down, aligning the positioning hole with the bottle mouth 6. For some tilted bottle mouths 6, although the positioning hole cannot be perfectly aligned, the bottle straightening plate 2 will still straighten the tilted bottle mouth 6 when it is pressed down, thus ensuring that all bottles are straight before capping. Then the capping device caps the bottle mouth 6. After capping, the bottle straightening plate 2 is moved up to remove the bottle with the cap on, ensuring that the cap is accurately closed. No manual straightening is required, thus achieving automation.

[0023] It should be noted that the extension distance of the bottle mouth 6 from the bottle body straightening plate 2 should be sufficient to ensure that the bottle cap can be closed onto the bottle mouth 6. For example, for a bottle cap with a closed mouth, the extension distance of the bottle mouth 6 should be greater than the thickness of the bottle cap.

[0024] For cylindrical bottles, the outer diameter of the positioning hole should be larger than the diameter of the bottle body. When straightening the bottle body, the upper surface of the positioning hole should descend to a preset distance before straightening the bottle body. This distance is optimal when the upper surface of the positioning hole is 2cm-10cm below the bottle mouth 6. For bottles whose cross-sectional dimensions gradually increase from top to bottom, the diameter of the positioning hole should be larger than the outer diameter of the bottle mouth 6, and the thickness of the bottle body straightening plate 2 should be less than the length of the bottle neck. To avoid the positioning hole getting stuck with the bottle body after the bottle mouth 6 is fitted onto the positioning hole due to the downward pressure of the positioning hole, the bottle body straightening plate 2 can be moved slightly upward after the capping mechanism is pressed down to prevent the positioning hole from getting stuck with the bottle body.

[0025] refer to Figure 1 and Figure 2 In one embodiment, the support frame is provided with a mounting plate 5 for fixing the drive device 4, so as to ensure that the drive device 4 can be more stable during the driving process.

[0026] refer to Figure 1 and Figure 2 In another embodiment, the drive device 4 is one of a cylinder, a hydraulic cylinder, or an electric push rod.

[0027] refer to Figure 1 and Figure 2 In one implementation, the positioning holes are set to at least two and evenly distributed on the bottle body straightening plate 2, and the spacing between adjacent positioning holes is set according to the spacing between the bottle grooves on the bottle feeding module 1.

[0028] refer to Figure 1 and Figure 2 In one embodiment, a photoelectric sensor for detecting whether the bottle is in position is provided below the bottle straightening plate 2. By setting the photoelectric sensor, it is possible to accurately determine whether the bottle delivery module 1 has reached the bottom of the bottle straightening plate 2, thereby improving the response speed.

[0029] refer to Figure 1 and Figure 2 In one embodiment, an annular washer is provided on the inner wall of the positioning hole. By providing the annular washer, wear on the bottle body can be avoided when the positioning hole is straightened.

[0030] refer to Figures 1-2 In one embodiment, the annular gasket is either a silicone gasket or a rubber gasket.

[0031] refer to Figures 1-2 In one implementation, the output end of the drive device 4 is connected to the bottle straightening plate 2 via an L-shaped connecting plate 3.

[0032] refer to Figures 1-2As one implementation method, the positioning hole is a flared mouth with the larger opening facing the bottle body. The inner diameter of the smaller diameter end of the flared mouth is larger than the outer diameter of the bottle mouth 6. By setting the flared mouth, the larger opening end is aligned with the bottle mouth 6, which further improves the guiding effect of the bottle mouth 6 and ensures the straightening effect.

[0033] It should be noted that the inner diameter of the smaller end of the flared mouth can also be larger than the outer diameter of the bottle body, as long as it can keep the bottle upright.

[0034] refer to Figure 1 As one implementation method, the bottle straightening plate 2 is one of aluminum alloy plate, stainless steel plate or engineering plastic plate.
