Description

Technical Field

[0001] The utility model relates to the technical field of capping machines, in particular to a bottle clamping mechanism of a linear capping machine. Background Art

[0002] The bottle clamping mechanism of a linear capping machine is used to seal the screw caps on various bottles, such as medicine bottles and beverage bottles, on the packaging production line. It typically features key workstations, including cap sorting, capping, and capping. These mechanisms coordinate and cooperate to complete the corresponding capping and sealing tasks. Because the bottles are placed directly on the conveyor and pressed against it by the capping device, when the motor in the capping device operates, the caps and bottles rotate relative to each other, making some bottles prone to tipping over. Chinese patent publication number "CN209522556U" discloses a fully automatic linear capping machine. This machine incorporates clamping mechanisms on both sides of the conveyor device, enabling the clamping devices to clamp the bottles on the conveyor device before capping them, reducing the probability of bottles toppling over during the capping process. However, with this method, when the bottles are placed on the conveyor belt, their position and adjacent spacing are difficult to control. In addition, during the conveyor belt transportation, the bottles may move on the conveyor belt, making it difficult for the arc groove of the clamping mechanism to align with the bottles, thereby clamping the bottles and rendering the clamping mechanism ineffective. Furthermore, the above method can only be used to clamp and fix bottles of one specification, and its practicality is relatively low. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a bottle clamping mechanism of a linear capping machine, which can fix bottles of different sizes and has a good fixing effect.

[0004] In order to solve the above technical problems, the utility model provides a bottle clamping mechanism for a linear capping machine, comprising:

[0005] Conveyor track;

[0006] There are two movable seats, which are respectively located on both sides of the conveying track, and the two movable seats can move relative to each other through an adjustment mechanism;

[0007] A limiting guide plate is provided on opposite sides of the two movable seats, with a passing space being defined between the two limiting guide plates;

[0008] The clamping mechanism includes a movable seat arranged on the movable seat and movable in the vertical direction of the conveying track. The movable seat is provided with a lifting seat. The lifting seat is movably provided with a plurality of fork rods arranged at equal distances along the conveying direction of the conveying track and extending in the direction of the conveying track. The plurality of fork rods are controlled by a pitch-changing mechanism to control the distance between two adjacent fork rods.

[0009] Furthermore, the adjustment mechanism includes an adjustment block fixed to the movable seat via a connecting piece, two adjustment blocks are screwed to both ends of the bidirectional adjustment screw and slidingly cooperate with the guide rod, and the bidirectional adjustment screw is arranged parallel to the guide rod.

[0010] Furthermore, the pitch changing mechanism includes a mounting vertical plate arranged on the lifting seat, a transverse slide rail is provided on the mounting vertical plate, the fork rod is slidably connected to the transverse slide rail through a slide seat, a movable plate that is lifted and lowered by the lifting mechanism is provided above the transverse slide rail, a transverse slide hole is provided on the movable plate, a connecting rod group is slidably provided in the transverse slide hole, each connecting rod group includes two connecting rods hinged to each other, and the other ends of the two connecting rods are respectively hinged to two adjacent slide seats.

[0011] Furthermore, the mounting vertical plate is provided with a vertical slide rail, the movable plate is slidably matched with the vertical slide rail, the lifting mechanism includes a vertical screw rotatably provided on the mounting vertical plate, and the movable plate is screwed to the vertical screw via a threaded block.

[0012] Furthermore, balls are provided on the facing sides of the two limiting guide plates.

[0013] The beneficial effects of the present invention are as follows: a conveyor track is used to convey bottles to the bottom of the capping device. When the movable seat moves relative to each other via an adjustment mechanism, the gap between the limiting guide plates on the two movable seats can be adjusted, thereby adjusting the passage space between the two limiting guide plates to accommodate bottles of different sizes, thereby improving the applicability of the bottle clamping mechanism of the linear capping machine. A clamping mechanism is provided on the movable seat and can also move with the movement of the movable seat, moving closer to or away from the conveyor track via the movable seat in a direction perpendicular to the conveyor track. When the movable seat moves toward the conveyor track, the fork rod on the movable seat can be inserted between the bottle openings of two adjacent bottles. The fork rod is provided on the lifting seat, which is provided on the movable seat. After the fork rod is inserted between the bottle openings of two adjacent bottles, the lifting seat descends, driving the fork rod on the lifting seat to descend and press the bottle against the conveyor track to maintain it in place. The spacing between the two adjacent fork rods should be adapted to the size of the bottle. The spacing between the two fork rods can be adjusted by the variable distance mechanism to accommodate bottles of different sizes. To sum up, the present invention limits the running path of the bottle body on the conveying track by setting two limiting guide plates. After entering between the two limiting guide plates in rows, the fork rod is forked between two adjacent bottles and pressed down on the neck of the bottle body to fix the bottle body. The bottle body can be effectively fixed to prevent the bottle body from tipping over or rotating. The spacing between the two limiting guide plates can be changed by the adjustment mechanism. The spacing between the two adjacent fork rods can be adjusted by the setting of the distance changing mechanism, thereby adapting to bottles of different sizes and increasing practicality.

DETAILED DESCRIPTION

[0018] With reference to the accompanying drawings, specific embodiments of the present invention will be described in detail.

[0019] Reference Figures 1 to 2 The utility model provides a bottle clamping mechanism for a linear capping machine, comprising:

[0020] The conveyor track 1 can be a conveyor in the prior art, typically comprising a conveyor belt, drive rollers, and a drive motor. The drive belt is mounted on a plurality of drive rollers, which can be rotated synchronously by chains, gears, or the like. The rotation of the drive rollers drives the conveyor belt to move, thereby driving the bottles to move along the transmission direction of the conveyor track 1. That is, the start and stop of the conveyor track 1 can be controlled by the start and stop of the drive motor. Of course, a position sensor can be provided on the conveyor track to detect the moving position of the bottles.

[0021] Two movable seats 2 are provided, one located on either side of the conveyor track 1. The two movable seats 2 can move relative to each other via an adjustment mechanism 3. The lower surface of the movable seat 2 is located at a higher level than the upper surface of the conveyor track 1, enabling the movable seat 2 to move on the conveyor track 1. Furthermore, the adjustment mechanism 3 includes an adjustment block 31 secured to the movable seat 2 via a connector 32. The two adjustment blocks 31 are threadedly connected to both ends of a bidirectional adjustment screw 33 and slidably engage a guide rod 34. The bidirectional adjustment screw 33 is arranged parallel to the guide rod 34. Of course, the bidirectional adjustment screw 33 is rotatably mounted on the frame of the capping machine, and the guide rod 34 is fixed to the frame. At this time, the connecting member 32 can adopt multiple connecting rods, the upper end of the connecting rod is fixed on the side of the moving seat 2 away from the transmission track, and the horizontal plane of the adjustment block 31 is lower than the horizontal plane of the transmission track 1, wherein the two ends of the bidirectional adjustment screw 33 are provided with threads with opposite rotation directions, and the two adjustment blocks 31 on both sides of the transmission track 1 are respectively screwed to the two ends of the bidirectional adjustment screw 33. When the bidirectional adjustment screw 33 rotates, the guide rod 34 and the adjustment block 31 slide together to stop the rotation of the adjustment block 31, so that the adjustment blocks 31 are closer to or farther away from each other on the bidirectional adjustment screw 33, and then the moving seat 2 is driven closer to or farther away from each other through the connecting member 32.

[0022] The limiting guide plates 4 are disposed on opposing sides of the two movable seats 2, with a passage space defined between the two limiting guide plates 4. Furthermore, ball bearings 41 are provided on the opposing sides of the two limiting guide plates 4 to reduce friction between the limiting guide plates 4 and the bottle, allowing the bottle to move smoothly between the two limiting guide plates 4. At this point, when the movable seats 2 approach each other, the two limiting guide plates 4 move closer together, narrowing the passage space to accommodate the passage of small bottles. When the movable seats 2 move away from each other, the two limiting guide plates 4 move away from each other, widening the passage space to accommodate the passage of large bottles. In other words, by driving the movable seats 2 toward or away from each other through the adjustment mechanism 3, the two limiting guide plates 4 can be driven toward or away from each other, thereby adjusting the passage space between the two limiting guide plates 4.

[0023] The clamping mechanism includes a movable seat 51 mounted on the movable seat 2 and movable in a vertical direction along the conveyor track 1. Specifically, the movable seat 51 is fixed to the output end of a first cylinder, which is also fixed to the movable seat 2. The movable seat 2 is also provided with a guide rail, and the movable seat 51 is provided with a guide groove that slides with the guide rail. The first cylinder is extended and retracted, driving the movable seat 51 toward or away from the conveyor track 1. In other words, under normal conditions, the movable seat 51 is located on the side of the movable seat 2 away from the conveyor track 1. When a bottle enters between the two limiting guide plates 4 and needs to be fixed, the movable seat 51 moves toward the conveyor track 1, thereby driving the fork rod 6 thereon to insert between two adjacent bottles.

[0024] The movable seat 51 is equipped with a lifting seat 52. The lifting seat 52 is movably mounted with a plurality of fork rods 6 arranged equidistantly along the conveying direction of the conveyor track 1 and extending toward the conveyor track 1. The spacing between two adjacent fork rods 6 is adapted to the size of the bottles. Furthermore, the movable seat 51 is equipped with a second cylinder. The output end of the second cylinder is fixed to the lifting seat 52. The second cylinder's telescopic movement drives the lifting seat 52 upward and downward. When the fork rods 6 are inserted between two bottles, the second cylinder drives the lifting seat 52 downward, pressing the fork rods 6 against the necks of the bottles, thereby securing the bottles.

[0025] Furthermore, the spacing between two adjacent fork rods 6 is controlled by a pitch-changing mechanism 7. The spacing between two adjacent fork rods 6 should be adapted to the size of the bottle. By adjusting the spacing between the two fork rods 6 through the pitch-changing mechanism 7, bottles of different sizes can be fixed. Furthermore, the pitch-changing mechanism 7 includes a mounting vertical plate 71 disposed on the lifting seat 52. The mounting vertical plate 71 is provided with a transverse slide rail 711. The fork rods 6 are slidably connected to the transverse slide rail 711 via the slide 61. Above the transverse slide rail 711 is a movable plate 72 that is raised and lowered by a lifting mechanism 73. The movable plate 72 is provided with a transverse slide hole 722. A connecting rod group 74 is slidably disposed within the transverse slide hole 722. Each connecting rod group 74 includes two mutually hinged connecting rods, which are hinged via a hinge shaft that slides in the transverse slide hole 722. The other ends of the two connecting rods are respectively hinged to two adjacent slide seats 61. When the movable plate 72 moves up and down under the action of the lifting mechanism 73, it drives the connecting rod group 74 to slide in the transverse sliding hole 722. At the same time, the angle between the two mutually hinged connecting rods changes, thereby changing the position of the two slides 61 hinged to the connecting rods, causing the slides 61 to slide on the transverse slide rails 711. When the position of the movable plate 72 is fixed, the position of the slides 61 on the transverse slide rails 711 is fixed, which can determine the position of the fork rods 6 and thus adjust the distance between two adjacent fork rods 6. Specifically, there can be multiple sets of fork rods 6.

[0026] Furthermore, the lifting mechanism 73 includes a vertical screw 731 rotatably mounted on the mounting vertical plate 71. The movable plate 72 is screwed to the vertical screw 731 via a threaded block 721. The mounting vertical plate 71 is also provided with a vertical slide rail 712, and the movable plate 72 slidably engages with the vertical slide rail 712. In this manner, the movable plate 72 is prevented from rotating by the sliding engagement of the vertical slide rail 712 with the movable plate 72, so that the rotation of the vertical screw 731 drives the movable plate 72 up and down on the vertical screw 731. Of course, the rotation of the vertical screw 731 can be driven by a motor or manually.

[0027] During operation, the spacing between two adjacent limiting guide plates 4 is adjusted using the adjustment mechanism 3 according to the size of the bottles, and the spacing between two adjacent fork rods 6 is adjusted using the pitch-changing mechanism 7. After adjustment, the conveyor track 1 is activated, and the bottles are placed on it. When the sensor detects that multiple bottles are located between the two limiting guide plates 4, the conveyor track 1 stops. The movable seat 51 is moved toward the conveyor track 1, thereby driving the fork rod 6 on the lifting seat 52 to insert between the bottle openings of two adjacent bottles. The lifting seat 52 is then moved downward, driving the fork rod 6 to press against the necks of the two bottles, securing the bottles. The capping operation can then begin. After capping is complete, the conveyor track 1 is activated to remove the capped bottles from between the two limiting guide plates 4.
