DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] like Figures 1 to 7 As shown, a PET bottle correction structure for filling dairy products includes a support seat 1, a correction mechanism and a filling mechanism, wherein the correction mechanism is arranged at the bottom of the support seat 1; the correction mechanism includes a first motor 2, a first screw rod 21 and a correction plate 25, four correction grooves 11 are opened at the bottom of the support seat 1, and the correction grooves 11 extend diagonally toward the center of the support seat 1, the first screw rod 21 is arranged in the correction groove 11, and a first bevel gear 22 is arranged at one end of the first screw rod 21 facing the inner center of the support seat 1, the first motor 2 is arranged at the top of the support seat 1, and a second bevel gear 23 is connected to the output end thereof, and the first bevel gear 22 and the second bevel gear 23 are meshed with each other, a slider 24 is arranged on the first screw rod 21, and a correction plate 25 is arranged on the slider 24; a transportation mechanism is arranged at the bottom of the support seat 1, and the transportation mechanism is used to transport PET bottles, and the filling mechanism is arranged at the center of the bottom of the support seat 1 for filling PET bottles.

[0030] When the PET bottle moves to the bottom of the support seat 1 on the transport mechanism, the sensor will detect the position of the PET bottle. The control system will start the first motor 2. When the first motor 2 rotates, the second bevel gear 23 drives the first bevel gear 22 to rotate, and then the first screw 21 rotates. Due to the threaded fit between the screw and the slider 24, the rotation of the screw will cause the slider 24 to move along the screw, and then drive the correction plate 25 to clamp and position the PET bottle around, and position the PET bottle directly under the filling mechanism, and then the filling mechanism mechanical energy is used for filling. When the PET bottle is filled, the first motor 2 rotates in the opposite direction, and the correction plate 25 returns to the initial position, waiting for the arrival of the next PET bottle.

[0031] The second bevel gear 23 is driven to rotate by the first motor 2, which drives the first bevel gear 22 and the first screw 21 to rotate, and then drives the correcting plate 25 to accurately correct the offset PET bottles, which can ensure that each PET bottle is in the correct position during the filling process, which helps to improve the accuracy and consistency of filling and reduce filling problems caused by position deviation. At the same time, the correcting plate 25 can clamp the PET bottle stably, improve the stability of the PET bottle during filling, and prevent the PET bottle from being unevenly stressed and offset during filling.

[0032] The transport mechanism includes a transport frame 3, a second motor 31 and a conveyor belt 32. The transport frame 3 is fixedly set on the ground, and the conveyor belt 32 is rotatably set on the transport frame 3. The second motor 31 is set on the side wall of the transport frame 3 to drive the transmission belt to rotate. Support plates 12 are set on both sides of the support seat 1. The support plates 12 are fixedly set on the ground, and the transport frame 3 is set in the middle of the support plates 12.

[0033] The conveyor belt 32 is driven to rotate by the second motor 31, thereby realizing the automatic transportation of the PET bottles. The transport rack 3 is arranged in the middle of the support plate 12, so that the conveyor belt 32 can smoothly transport the PET bottles to the filling position below the support seat 1. When the PET bottles are transported to the filling position below the support seat 1, the conveyor belt 32 will temporarily stop rotating to allow the filling mechanism to perform the filling operation; after the filling is completed, the conveyor belt 32 will start again to transport the filled PET bottles to the next position.

[0034] The filling mechanism includes a collecting cylinder 4 and a filling cylinder 41 . The collecting cylinder 4 is fixedly arranged on the top of the support seat 1 , and the filling cylinder 41 is fixedly arranged at the center of the bottom of the support seat 1 . A flow tube 42 is arranged between the filling cylinder 41 and the collecting cylinder 4 .

[0035] When the PET bottle is accurately transported to the filling position by the transportation mechanism and stabilized and corrected by the correction mechanism; the filling process begins, the dairy product flows out of the collecting cylinder 4, enters the filling cylinder 41 through the circulation tube 42, and the outlet of the filling cylinder 41 is tightly connected with the bottle mouth of the PET bottle to ensure that the dairy product can be accurately filled into the PET bottle; during the filling process, the amount of dairy product filled each time can be controlled by controlling the opening and closing time of the filling cylinder 41 and adjusting the flow rate of the circulation tube 42.

[0036] A preliminary guiding mechanism is arranged on the transport mechanism, and the preliminary guiding mechanism is close to the feeding end of the transport frame 3; the preliminary guiding mechanism includes a guide seat 5, a third motor 51 and a guide plate 54, the guide seat 5 is fixedly arranged at the bottom of the transport frame 3, a second screw rod 52 is arranged in the guide seat 5, the third motor 51 is arranged on the side wall of the guide seat 5, and its output end is connected with the second screw rod 52, a blocking ring 53 is arranged in the middle position of the second screw rod 52, the thread teeth on both sides of the blocking ring 53 are in opposite directions, the guide plates 54 are arranged on both sides of the blocking ring 53, the bottom of the guide plate 54 is arranged on the second screw rod 52, and the top of the guide plate 54 is arranged above the conveyor belt 32.

[0037] The second screw rod 52 is driven to rotate by the third motor 51. Due to the existence of the blocking ring 53, the guide plates 54 on both sides of the second screw rod 52 will move towards each other and gradually approach the two sides of the conveyor belt 32. When the PET bottles are conveyed on the conveyor belt 32, the guide plates 54 will guide the PET bottles that are offset on the conveyor belt 32 to the correct position, so that the PET bottles can be arranged and conveyed according to the predetermined path and direction, which helps to improve the accuracy and efficiency of subsequent filling. At the same time, it can be applicable to PET bottles of different sizes and improve the adaptability of the device.

[0038] A first rounded corner 541 is provided on one side of the top of the guide plate 54 facing the feeding end of the transport rack 3 .

[0039] The first rounded corner 541 is provided to help guide the PET bottle to flow along a predetermined path and direction. When the PET bottle contacts the guide plate 54, the first rounded corner 541 can make it change direction more smoothly, avoid jamming or deviation, and reduce friction and wear.

[0040] A buffer plate 6 is arranged on the slider 24, the buffer plate 6 is close to the center of the support seat 1, and a spring 63 is arranged between the buffer plate 6 and the correcting plate 25, and second rounded corners 62 are arranged on the side walls on both sides of the buffer plate 6; a slide groove 241 is arranged on the slider 24, and a limiting block 61 is arranged at the bottom of the buffer plate 6, and the limiting block 61 is slidably matched with the slide groove 241.

[0041] By providing the buffer plate 6 and the spring 63, when the PET bottle is corrected, the buffer plate 6 first contacts the PET bottle, and the impact force is buffered by the spring 63, thereby reducing the squeezing and damage to the PET bottle body during correction and clamping. At the same time, the sliding cooperation between the slide groove 241 and the limit block 61 improves the stability of the buffer plate 6 when under pressure, thereby improving the stability of the correction and clamping of the PET bottle.

[0042] The working principle of the present invention is as follows: when the PET bottle is transported to the bottom of the support seat 1 through the transport mechanism, the preliminary guide mechanism first drives the guide plate 54 to adjust the position through the third motor 51, and guides the PET bottle into the correct transport path. Subsequently, the sensor detects the position of the PET bottle, and the control system starts the first motor 2, which drives the first screw 21 to rotate through the bevel gear transmission, so that the slider 24 drives the correction plate 25 to move along the screw, and the PET bottle is accurately clamped and positioned. During the filling process, the dairy product enters the filling cylinder 41 from the collection cylinder 4 through the circulation tube 42, and the PET bottle is filled.
