Description
Technical Field
[0001] This utility model relates to the field of edible oil processing and packaging technology, and in particular to a capping mechanism for an edible oil filling machine. Background Technology
[0002] In the production and packaging of edible oil, capping is one of the key processes. The filling machine is used to inject a certain amount of edible oil into the bottle. Then, the cap feeding mechanism places the cap at the opening of the bottle, and the cap pressing mechanism completes the cap sealing to ensure product sealing, extend shelf life, and meet food safety requirements.
[0003] In automated edible oil filling production lines, conveyor belt systems are widely used for the continuous transport of bottles, conveying filled oil bottles to the capping station for sealing. Traditional conveyor belt systems typically operate in a continuous mode, where the bottles move at a constant speed on the conveyor belt, and the capping mechanism performs dynamic capping operations as the bottles pass by. However, during the capping process, because the conveyor belt continues to run and the bottles are in motion, it is difficult for the capping mechanism to achieve stable alignment and effective clamping with the bottles. This easily leads to problems such as cap position deviation, loose caps, and poor sealing, seriously affecting the capping quality and product qualification rate.
[0004] Therefore, a capping mechanism for an edible oil filling machine is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a capping mechanism for an edible oil filling machine to solve the above-mentioned problems. This improves the problem that, due to the continuous operation of the conveyor belt and the movement of the bottle, the capping mechanism of the edible oil filling machine is difficult to achieve stable alignment and effective clamping with the bottle, which easily causes problems such as cap position deviation, loose cap pressing, and poor sealing, seriously affecting the capping quality and product qualification rate.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: a capping mechanism for an edible oil filling machine, comprising: Mounting plate; A conveyor belt, which is mounted on the upper end of a mounting plate, and the main shaft of the conveyor belt is rotatably connected to both ends of the mounting plate; An electric motor is mounted on one side of the mounting plate; A semi-circular block, which is fixedly connected to the output shaft of the motor; A slider, which is fixedly connected to one side of the semicircular block; The drive block is fixedly connected to the circumferential surface of the main shaft of the conveyor belt; Four U-shaped grooves are respectively opened at the four corners of the drive block, and the slider is slidably connected to the four U-shaped grooves in turn; A gantry frame, which is fixedly connected to the upper end of the mounting plate; A capping mechanism is provided on the lower side of the gantry frame to clamp and cap the edible oil bottle.
[0007] Preferably, the capping mechanism includes a cylinder, a pneumatic rod, a pressure block, a spring, an electric push rod, and an arc-shaped clamping block. Two pressure blocks, electric push rods, and arc-shaped clamping blocks are provided, and four springs are provided. The cylinder is fixedly connected to the upper end of the gantry frame by bolts. The pneumatic rod is fixedly connected to the output end of the cylinder. Two pressure blocks are respectively disposed at the lower end of the pneumatic rod, with one pressure block fixedly connected to the lower end of the pneumatic rod. The four springs are respectively fixedly connected to the adjacent ends of the two pressure blocks. Two electric push rods are respectively fixedly connected to one side of the inner wall of the gantry frame, and two arc-shaped clamping blocks are respectively fixedly connected to the adjacent ends of the two electric push rods by bolts.
[0008] Preferably, a stabilizing groove is provided on each of the inner walls of the two sides of the gantry frame, and a stabilizing block is slidably connected in each stabilizing groove. Another pressure block is fixedly connected to the close ends of the two stabilizing blocks.
[0009] Preferably, the surface of the conveyor belt is provided with a guide groove, and the arc-shaped clamps are located at the two sides of the guide groove when the two electric push rods retract.
[0010] Preferably, a fixing block is fixedly connected to the upper end of the mounting plate, and a motor is fixedly connected to the upper end of the fixing block by bolts.
[0011] Preferably, multiple telescopic rods are fixedly connected to the adjacent ends of the two pressure blocks, and a spring is sleeved on the circumferential surface of each telescopic rod.
[0012] Preferably, two support blocks are fixedly connected to the lower end of the mounting plate.
[0013] The beneficial effects of this utility model are: This device uses an intermittent transmission mechanism consisting of a motor, a semi-circular block, a slider, a drive block, and a U-shaped groove to drive the conveyor belt in a step-by-step and stop-and-go manner. When the oil bottle is accurately transported to the capping station, the conveyor belt stops completely, bringing the oil bottle to a static and stable state. Capping is then performed on this basis. This avoids the defects of traditional continuous conveyor belts, such as capping position deviation, misalignment, loose pressing, and poor sealing caused by bottle movement. It ensures the verticality, stability, and pressure uniformity of the capping action, thereby significantly improving the sealing reliability, appearance quality, and overall product qualification rate of the caps.
[0014] This device uses an arc-shaped clamp driven by an electric actuator and a pressure block driven by a cylinder. During operation, the arc-shaped clamp first clamps the oil bottle horizontally from both sides, effectively fixing the bottle and preventing it from shaking, tilting, or tipping over when the cap is pressed. Then, the pressure block presses down vertically to complete the capping. This "clamp first, then press" coordinated operation mode effectively prevents the oil bottle from shaking, tilting, or shifting due to force during the capping process, ensuring the verticality and stability of the cap.

[0017] 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. Example 1
[0018] Please see Figures 1-4 The present invention provides the following technical solution: A capping mechanism for an edible oil filling machine includes: Mounting plate 1; Conveyor belt 2 is installed on the upper end of mounting plate 1, and the main shaft of conveyor belt 2 is rotatably connected to both ends of mounting plate 1. Motor 3 is mounted on one side of mounting plate 1; Semicircular block 4 is fixedly connected to the output shaft of motor 3; Slider 5 is fixedly connected to one side of the semicircular block 4; Drive block 6 is fixedly connected to the circumferential surface of the main shaft of conveyor belt 2; Four U-shaped grooves 7 are respectively opened at the four corners of the drive block 6, and the slider 5 is slidably connected to the four U-shaped grooves 7. Gantry 8 is fixedly connected to the upper end of mounting plate 1; A capping mechanism is located on the lower side of the gantry 8 to clamp and cap the edible oil bottle.
[0019] In a specific embodiment of this utility model, the mounting plate 1 is used to install components such as the conveyor belt 2. When it is necessary to cap the edible oil bottle, when the motor 3 is started, the output shaft of the motor 3 drives the semicircular block 4, which is fixedly connected to it, to rotate synchronously. The slider 5, which is fixed to one side of the semicircular block 4, will make an eccentric circular motion as the semicircular block 4 rotates. When the slider 5 rotates with the semicircular block 4, its end is inserted into and slidably connected to the four U-shaped grooves 7 on the drive block 6. Due to the eccentric motion of the slider 5, when it enters a certain U-shaped groove 7, it pushes the drive block 6 to rotate at a certain angle. Then the slider 5 disengages from the U-shaped groove 7. When the slider 5 enters the next U-shaped groove 7, it pushes the drive block 6 to rotate again. In this way, the drive block 6 rotates intermittently with the slider 5. Under the thrust of the conveyor belt, intermittent rotational motion is achieved. The drive block 6 is fixedly connected to the main shaft of the conveyor belt 2, thus enabling the conveyor belt 2 to stop and start periodically. This allows for accurate positioning and stopping of the bottle at the capping station. When the conveyor belt 2 stops, the bottle is precisely positioned at the capping position below the gantry 8. In this way, when the capping mechanism starts, it can stably clamp the stationary bottle and complete the capping operation, effectively avoiding problems such as capping position deviation and incomplete sealing caused by the continuous operation of the conveyor belt 2. After capping is completed, the conveyor belt 2 starts again, transporting the capped oil bottle to the next process. This cycle repeats, achieving efficient and precise intermittent capping operation on the edible oil filling line.
[0020] Please refer to the details. Figures 1-4 The capping mechanism includes a cylinder 9, a pneumatic rod 10, a pressure block 11, a spring 12, an electric push rod 13, and an arc-shaped clamping block 14. There are two pressure blocks 11, two electric push rods 13, and two arc-shaped clamping blocks 14. There are four springs 12. The cylinder 9 is fixedly connected to the upper end of the gantry frame 8 by bolts. The pneumatic rod 10 is fixedly connected to the output end of the cylinder 9. The two pressure blocks 11 are respectively set at the lower end of the pneumatic rod 10, and one of the pressure blocks 11 is fixedly connected to the lower end of the pneumatic rod 10. The four springs 12 are respectively fixedly connected to the near ends of the two pressure blocks 11. The two electric push rods 13 are respectively fixedly connected to the inner wall of one side of the gantry frame 8. The two arc-shaped clamping blocks 14 are respectively fixedly connected to the near ends of the two electric push rods 13 by bolts.
[0021] In this embodiment: when the bottle enters below the capping mechanism, two electric push rods 13 are pushed horizontally out from the inner walls of both sides of the gantry frame 8, driving the arc-shaped clamping block 14 at its front end to move towards the middle, clamping the bottle body and preventing the bottle from shaking or tipping over during the capping process. Then, the cylinder 9 is activated, and the pneumatic rod 10 at its output end extends downward. In this way, a pressure block 11 fixedly connected to the lower end of the pneumatic rod 10 descends accordingly. At the same time, the pressure block 11 is elastically connected to another pressure block 11 through four springs 12, so that the two pressure blocks 11 move down synchronously under the drive of the pneumatic rod 10, but have a certain buffering and adaptive adjustment capability, which can adapt to bottle caps of different heights or slight inclinations, ensuring that the capping force is evenly distributed. When the capping action is performed, the two pressure blocks 11 work together on the top of the bottle cap to complete the pressing. The cylinder 9 drives the pressure block 11 to vertically press the cap, and the electric push rod 13 drives the arc-shaped clamping block 14 to horizontally clamp, realizing a stable operation process of clamping first and then capping, which significantly improves the accuracy and reliability of capping.
[0022] Please refer to the details. Figures 1-4 A stabilizing groove 15 is provided on each of the inner walls of the two sides of the gantry frame 8. A stabilizing block 16 is slidably connected in each stabilizing groove 15. Another pressure block 11 is fixedly connected to the close ends of the two stabilizing blocks 16.
[0023] In this embodiment: when the pressing block 11 slides synchronously with the stabilizing block 16 along the stabilizing groove 15, its movement trajectory is strictly limited to the vertical direction, which effectively prevents the pressing block 11 from shaking or tilting during the pressing process, ensuring the verticality and stability of the capping action, avoiding problems such as bottle cap deformation and poor sealing caused by bias pressure, and further ensuring the capping quality.
[0024] Please refer to the details. Figures 1-4 The surface of the conveyor belt 2 is provided with a guide groove 17, and when the two electric push rods 13 retract, the arc-shaped clamps 14 are located at the two sides of the guide groove 17.
[0025] In this embodiment: the personnel place the oil bottle body into the guide groove 17 on the conveyor belt 2 for transmission. When the electric push rod 13 drives the arc-shaped clamping block 14 to move towards the oil bottle body for clamping, the guide groove 17 on the surface of the conveyor belt 2 provides clearance space for the movement of the arc-shaped clamping block 14. When the electric push rod 13 is fully retracted and the arc-shaped clamping block 14 is in the retracted state, its position is exactly at the two sides of the guide groove 17. It will not protrude from the surface of the conveyor belt 2 and obstruct the normal transmission of the oil bottle, and it can also ensure that the arc-shaped clamping block 14 can smoothly extend from both sides and clamp the bottle body during the clamping action.
[0026] Please refer to the details. Figures 1-4 A fixing block 18 is fixedly connected to the upper end of the mounting plate 1, and a motor 3 is fixedly connected to the upper end of the fixing block 18 by bolts.
[0027] In this embodiment, the fixing block 18 fixed at the upper end of the mounting plate 1 plays a key supporting and connecting role for the motor 3. The motor 3 is firmly installed on the upper end of the fixing block 18 by bolts, so that the relative position between the output shaft of the motor 3 and the main shaft of the conveyor belt 2 remains stable. The fixing block 18 is C-shaped, and its C-shaped notch allows personnel to put tools in, making it convenient for personnel to pick up and put down tools.
[0028] Please refer to the details. Figures 1-4 Multiple telescopic rods 19 are fixedly connected to the close ends of the two pressure blocks 11, and a spring 12 is sleeved on the circumferential surface of each telescopic rod 19.
[0029] In this embodiment: when the two pressure blocks 11 press down on the bottle cap together under the drive of the pneumatic rod 10, the multiple telescopic rods 19 and the springs 12 sleeved on them between the close ends of the two pressure blocks 11 play an important role in buffering and equalizing pressure. The multiple telescopic rods 19 are used to increase the stability of the connection between the two pressure blocks 11 and limit the springs 12 to prevent the springs 12 from bending during compression.
[0030] Please refer to the details. Figures 1-4 Two support blocks 20 are fixedly connected to the lower end of the mounting plate 1.
[0031] In this embodiment, the support block 20 firmly supports the mounting plate 1 on the ground or equipment base, effectively dispersing the vibration and stress during equipment operation and preventing the mounting plate 1 from bending or deforming due to uneven force.
[0032] When the production line is started, the motor 3 starts to run, and its output shaft drives the fixedly connected semicircular block 4 to rotate. The slider 5 on the semicircular block 4 then makes an eccentric circular motion and periodically inserts into the U-shaped grooves 7 at the four corners of the drive block 6. Each time the slider 5 inserts into the U-shaped groove 7, it pushes the drive block 6 to rotate a certain angle and then slides out. When the slider 5 enters the next U-shaped groove 7, it is pushed again. This intermittent thrust enables the drive block 6 and the main shaft of the connected conveyor belt 2 to achieve intermittent stepping motion. Thus, the conveyor belt 2 periodically runs and stops, precisely transporting the filled and capped edible oil bottles to the capping station below the gantry 8, where they remain stably stationary. When the conveyor belt 2 stops and the oil bottle is fully positioned at the capping station, firstly, the two electric actuators 13 move synchronously, pushing their front-end arc-shaped clamps 14 horizontally towards the bottle body. The arc-shaped clamps 14 extend from both sides of the guide groove 17 on the surface of the conveyor belt 2, precisely clamping the oil bottle below the shoulder, firmly fixing the bottle. After the oil bottle is firmly clamped by the arc-shaped clamps 14, the cylinder 9 starts, and its output pneumatic rod 10 extends downwards, driving the... One of the pressure blocks 11 directly connected to it moves downwards, while simultaneously pulling another pressure block 11 connected to the stabilizing block 16 downwards through the elastic connection of four springs 12 and multiple telescopic rods 19. Under the guidance of the stabilizing block 16 along the stabilizing groove 15, the two pressure blocks 11 remain vertical and stable as they approach and contact the top of the bottle cap. Under the continuous thrust of the cylinder 9, the pressure blocks 11 apply a uniform and stable downward pressure to the bottle cap, completing the sealing process. During this process, the telescopic rods 19 and springs 12 provide buffering to accommodate minor deviations, ensuring uniform pressure and preventing the bottle cap from deforming or being pressed too tightly. By clamping before capping, the method effectively prevents the oil bottle from shaking, tilting, or shifting due to force during the capping process, ensuring the verticality and stability of the cap.
[0033] It should be noted that the connection and use of the conveyor belt 2, motor 3, cylinder 9, pneumatic rod 10 and electric push rod 13 in this solution are all existing technologies, and this solution will not elaborate on them further.
