Description

Technical Field

[0001] This utility model relates to the field of toothpaste filling production lines, and in particular to a toothpaste filling production line that has the function of removing defective products with the tail end cut off. Background Technology

[0002] The toothpaste filling production process includes a toothpaste tube dispensing mechanism, a cursor control mechanism, a paste filling mechanism, a toothpaste tube end heating mechanism, a tail-pressing mechanism, an air-cooling mechanism, a tail-cutting mechanism, a toothpaste unloading mechanism, and a toothpaste collection mechanism, all installed along the toothpaste tube conveyor line. Empty toothpaste tubes are fed into a cup holder on the conveyor line by the dispensing mechanism and then conveyed backwards. During this process, the toothpaste tube undergoes cursor positioning, paste filling, end-cap heating, tail-pressing, cooling, and tail-cutting before being unloaded from the conveyor line. In this process, due to loose cup holders or foreign objects adhering and lifting the toothpaste tube during the heating process, the tail end of the tube may be higher than normal. During the subsequent tail-cutting, the pressed tail portion of the toothpaste tube is removed. If these unsealed, defective products are not removed and are automatically packaged by the packaging machine and enter the market, it will result in very negative customer reviews. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a toothpaste filling production line with a function to remove defective products with cut-off tails. Defective toothpaste products with cut-off tails during production can be detected and removed in a timely manner, ensuring the quality of products entering the market.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This toothpaste filling production line features a mechanism for rejecting defective tubes by cutting off the tail end. It includes a conveyor belt with holes spaced at intervals for holding cup holders. A toothpaste tube dispensing mechanism is located on the side of the conveyor belt, dispensing toothpaste tubes one by one into the cup holders. Above the toothpaste tubes during transport, a toothpaste filling mechanism, a toothpaste tube tail-end heating mechanism, a tail-pressing mechanism, an air-cooling mechanism, and a tail-cutting mechanism are sequentially arranged. A sensor monitoring the toothpaste tube height is located in front of the tail-cutting mechanism, and the sensor signal is connected to the production line controller. When the sensor detects a defective tube, it passes smoothly; when a defective tube passes by, the sensor signal is transmitted to the production line controller, the equipment stops, and the operator handles the situation.

[0006] A further improvement is that the sensor is a slot-type sensor. Qualified products with a normal height can pass through smoothly, while defective products, with a height exceeding the normal position, will be detected when they flow into the sensor.

[0007] A further improvement involves installing separate unloading mechanisms for genuine and defective toothpaste tubes on the inner side of the toothpaste tube conveyor behind the tail-cutting mechanism. A controller signal is connected to these mechanisms. Correspondingly, genuine and defective toothpaste collection mechanisms are located on the outer side. When a sensor detects a defective product, the production controller activates the drive mechanism of the defective toothpaste unloading mechanism, automatically removing the defective toothpaste from the production line and transferring it to the defective toothpaste collection mechanism.

[0008] A further improvement is that the unloading mechanism for genuine toothpaste and the unloading mechanism for defective toothpaste are telescopic push rods, respectively.

[0009] A further improved design features a circular turntable conveyor belt, which occupies a smaller area.

[0010] A further improvement is to include a cursor control mechanism on the front of the toothpaste filling mechanism. This allows the cursor on each toothpaste tube to be uniformly adjusted to a set position, ensuring the toothpaste tube label is displayed on the front after compression.

[0011] A further improvement is that the cursor control mechanism includes a cursor detection device erected on the side of the conveyor belt and a rotary positioning motor located below the cup holder. When the cup holder with the toothpaste tube moves to the side of the cursor detection device, the rotary positioning motor moves upward and engages the cup holder to rotate. The cursor detection device scans and identifies the cursor on the toothpaste tube. Once the cursor is identified, the rotary positioning motor stops rotating, allowing the toothpaste tube to reach a preset angle. Beneficial effects

[0012] This invention adds a sensor before the tail-cutting process in a toothpaste filling production line. The sensor detects the height of the toothpaste tubes. When a toothpaste tube that is higher than the normal height passes by, the signal is transmitted to the production line controller, which controls the defective toothpaste tube unloading mechanism to operate when the defective toothpaste tube arrives, thus removing the defective toothpaste tube.

[0014] Figure 2 This is a partial front view structural diagram of the present utility model. Detailed Implementation

[0015] like Figure 1 , Figure 2As shown, the toothpaste filling production line is a mature production equipment for toothpaste manufacturers. It includes a variety of mature supporting devices for the conveyor belt carrying the toothpaste tubes, the toothpaste tube dispensing mechanism, the cursor control mechanism, the paste filling mechanism, the toothpaste tube end heating mechanism, the tail pressing mechanism, the air blowing cooling mechanism, the tail cutting mechanism, and the toothpaste tube unloading mechanism. These are existing technologies well-known to those skilled in the art. This utility model includes a conveyor belt 1 with holes spaced apart on a ring turntable for holding cup holders 2. A toothpaste tube dispensing mechanism 3 is located on one side of the conveyor belt, dispensing toothpaste tubes one by one into the cup holders 2. Above the toothpaste tubes during transport, a paste filling mechanism 5, a toothpaste tube end heating mechanism 6, a tail pressing mechanism 7, an air blowing cooling mechanism 8, and a tail cutting mechanism 10 are sequentially arranged. A sensor 9 for monitoring the height of the toothpaste tubes is located in front of the tail cutting mechanism 10, and the sensor 9's signal is connected to the production line controller. The toothpaste filling mechanism 5 is equipped with a cursor control mechanism 4 at its front. The cursor control mechanism 4 includes a cursor detection device 41 erected on the side of the conveyor belt and a rotary positioning motor 42 located below the cup holder. On the inner side of the toothpaste tube conveying path behind the tail-cutting mechanism 10, there are respectively a genuine toothpaste unloading mechanism 11 and a defective toothpaste unloading mechanism 12. The controller signal is connected to the genuine toothpaste unloading mechanism 11 and the defective toothpaste unloading mechanism 12 (telescopic push rod). On the outer side, there are corresponding genuine toothpaste collection mechanisms 13 and defective toothpaste collection mechanisms 14.

[0016] In this embodiment, the toothpaste tube insertion mechanism 3 is a V-shaped toothpaste tube storage rack with two pneumatically propelled insertion slots in the middle. One toothpaste tube from each of the two side storage racks slides into the insertion slot. A cylinder pushes the outer end of the horizontally placed insertion slot to lift the toothpaste tube, placing it upright into the cup holder on the conveyor belt. When the toothpaste tube reaches the cursor control mechanism 4 with the conveyor belt, the rotary positioning motor rotates and engages the cup holder. The cursor detection device scans and identifies the cursor on the toothpaste tube. If the cursor is detected, the rotary positioning motor stops rotating, allowing the toothpaste tube to reach a preset angle. The conveyor belt carries the toothpaste tube to below the paste filling mechanism. A lower push rod pushes the cup holder and toothpaste tube upwards, and the paste filling gun is inserted into the toothpaste tube to squeeze in toothpaste. Then, the push rod retracts, and the toothpaste tube falls back into place. The conveyor belt carries the toothpaste tube filled with toothpaste to below the heating mechanism at the end of the toothpaste tube. A lower push rod pushes the cup holder and toothpaste tube upwards, and the heating rod is inserted into the toothpaste tube. The inner wall of the inner end is heated around the perimeter. Normally, the push rod retracts and the toothpaste tube falls back to its original position. However, if the heating rod is not clean, the toothpaste tube may stick and rise higher than normal. The conveyor belt carries the toothpaste tube to the tail-pressing mechanism, where two pressure plates squeeze and seal the heated end of the toothpaste tube. The conveyor belt then carries the sealed toothpaste tube to the air-cooling mechanism for cooling. After passing through a sensor, toothpaste tubes of normal height pass smoothly, while those that are too tall will trigger a sensor signal to the production line controller. When passing through the tail-cutting mechanism, the tail of the tall toothpaste tube will be cut off, forming a defective product. When the defective toothpaste tube reaches the defective toothpaste unloading mechanism, the controller controls the defective toothpaste unloading mechanism to push the defective toothpaste to the defective toothpaste collection mechanism. When the genuine toothpaste tube reaches the genuine toothpaste unloading mechanism, the genuine toothpaste unloading mechanism pushes the genuine toothpaste to the genuine toothpaste collection mechanism, thus preventing defective toothpaste from being packaged and entering the market.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
