Technical Field

[0001] The utility model relates to the technical field of bottle cap packaging, in particular to a packaging bottle cap screwing device. Background Art

[0002] With the improvement of living standards, bottled beverages appear in an endless stream on supermarket shelves. In order to ensure the safety and hygiene of bottled beverages, they need to be sealed with bottle caps, and a capping device is needed in this link.

[0003] In order to reduce the degree of manual involvement, the existing capping process first transfers the bottle cap to the bottom of the capping device, uses the capping device to clamp the bottle cap, and then the capping device drives the bottle cap to move to the bottom of the bottle body, and the driving source causes the capping device to fall and rotate, so as to smoothly perform the capping activity.

[0004] The existing device still has problems when in use: since the clamping device needs to drive the bottle cap to move, the specifications and sizes of the bottle caps it can clamp are relatively fixed. When processing different production batches, it is necessary to replace the corresponding specifications of the capping device, and it is necessary to purchase different specifications of the capping devices, which is costly and time-consuming and labor-intensive to install. Utility Model Content

[0005] The utility model aims to solve the problems existing in the prior art and proposes a packaging bottle cap screwing device, which can clamp bottle caps of different diameters and meet different usage requirements.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A packaging bottle capping device comprises a housing, a drop rod is slidably mounted on the housing, and a pressing block is fixedly mounted on the drop rod;

[0008] A mounting frame is fixedly installed inside the shell, and three clamping devices are slidably installed on the mounting frame;

[0009] A rotating disk is rotatably installed inside the shell, and a spiral groove adapted to the clamping device is provided on the side of the rotating disk away from the pressing block;

[0010] A transmission gear is fixedly installed at the center of one side of the rotating disk close to the pressing block.

[0011] Preferably, the clamping device comprises a movable rack which is slidably mounted on a mounting frame, a mounting rod being fixedly mounted on the movable rack, and clamping plates being fixedly mounted on the mounting rod at equal distances and evenly.

[0012] Preferably, the clamping plates on the three clamping devices are installed in a staggered manner, and the rotation of the rotating disk can cause the three clamping devices to move synchronously toward the center of the circle.

[0013] Preferably, a fixed rack is embedded on the drop rod, a rotating gear and a vertical bevel gear are rotatably installed inside the shell, the teeth on the fixed rack match the tooth grooves on the rotating gear, the rotating gear is connected to the transverse bevel gear through the first connecting rod, and the vertical bevel gear is connected to the driven gear through the second connecting rod.

[0014] Preferably, the transverse bevel gear and the vertical bevel gear, the transmission gear and the driven gear are all in meshing relationship.

[0015] Preferably, a fixing ring is fixedly mounted on the drop rod, a return spring is fixedly mounted on the fixing ring, and the other end of the return spring is fixedly mounted on the housing.

[0016] Preferably, vertical lines are evenly and equidistantly formed on the plurality of groups of clamping plates.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] (1) The utility model abandons the traditional open-type clamping jaws by providing a mounting frame, a rotating disk, a transmission gear, a movable rack, a mounting rod, a clamping plate and a spiral groove. By making three groups of clamping plates synchronously perform linear motion toward the center of a circle, and staggeredly installed clamping plates, the clamping plates can overlap, and the three groups of clamping plates at different positions can form a closed space with an inscribed circle.

Therefore, by controlling the falling distance of the drop rod, the device can be suitable for bottle caps of different sizes. The adjustment operation is simple and convenient, and the applicability is stronger. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] See also Figures 1 to 6 A packaging bottle cap screwing device includes a shell 1, a drop rod 3 is slidably mounted on the shell 1, and a pressing block 6 is fixedly mounted on the drop rod 3. By applying a certain pressure to the pressing block 6, the drop rod 3 can be lowered to perform the bottle cap grabbing activity.

[0029] A mounting frame 7 is fixedly installed inside the housing 1, and three clamping devices 2 are slidably installed on the mounting frame 7. The three clamping devices 2 can move synchronously in the center direction of the circle, and can clamp bottle caps of different specifications;

[0030] A rotating disk 8 is rotatably mounted inside the housing 1, and a spiral groove 13 adapted to the clamping device 2 is provided on the side of the rotating disk 8 facing away from the pressing block 6;

[0031] A transmission gear 9 is fixedly mounted at the center of one side of the rotating disk 8 close to the pressing block 6. By rotating the transmission gear 9, the rotating disk 8 can be rotated synchronously, thereby moving the clamping device 2.

[0032] like Figure 3 As shown, the clamping device 2 includes a movable rack 10, which is slidably mounted on the mounting frame 7, a mounting rod 11 is fixedly mounted on the movable rack 10, and clamping plates 12 are fixedly mounted on the mounting rod 11 at equal intervals.

[0033] When the rotating disk 8 rotates, since the moving rack 10 is adapted to the spiral groove 13, the rotation of the rotating disk 8 will cause the moving rack 10 to move on the spiral groove 13, and then the three moving racks 10 will move synchronously toward or away from the center of the circle, and then the clamping device 2 as a whole will also move synchronously.

[0034] like Figure 3 and Figure 5 As shown, the clamping plates 12 on the three clamping devices 2 are installed in a staggered manner, and the rotation of the rotating disk 8 can cause the three clamping devices 2 to move synchronously toward the center of the circle.

[0035] The staggered installation of the clamping plates 12 allows the clamping plates 12 to overlap, and three groups of clamping plates 12 at different positions can form a space with an inscribed circle, so bottle caps of different specifications can be clamped.

[0036] like Figure 6 As shown, a fixed rack 14 is embedded in the drop rod 3, and a rotating gear 15 and a vertical bevel gear 18 are rotatably installed inside the shell 1. The teeth on the fixed rack 14 are matched with the tooth grooves on the rotating gear 15. The rotating gear 15 is connected to the transverse bevel gear 17 through the first connecting rod 16, and the vertical bevel gear 18 is connected to the driven gear 20 through the second connecting rod 19.

[0037] like Figure 6 As shown, the transverse bevel gear 17 and the vertical bevel gear 18, the transmission gear 9 and the driven gear 20 are all in meshing relationship.

[0038] When the cylinder drives the drop rod 3 to fall, the fixed rack 14 causes the rotating gear 15 to rotate, and the rotation of the rotating gear 15 is transmitted to the transverse bevel gear 17 through the first connecting rod 16. The transverse bevel gear 17 rotates the vertical bevel gear 18 through meshing, and the rotation of the vertical bevel gear 18 is transmitted to the driven gear 20 through the second connecting rod 19, and then the driven gear 20 causes the transmission gear 9 to rotate.

[0039] The transmission gear 9 is fixedly mounted on the rotating disk 8, so the rotating disk 8 can be smoothly rotated, thereby moving the clamping device 2 to perform the bottle cap clamping activity.

[0040] like Figure 1 As shown, a fixing ring 5 is fixedly mounted on the drop rod 3 , a return spring 4 is fixedly mounted on the fixing ring 5 , and the other end of the return spring 4 is fixedly mounted on the housing 1 .

[0041] Through the elastic force of the reset spring 4, when there is no external force, the fixing ring 5 can smoothly drive the drop rod 3 to reset, and then the clamping device 2 moves in the opposite direction to perform the bottle cap clamping operation.

[0042] like Figure 3 As shown, multiple groups of clamping plates 12 are uniformly and evenly provided with vertical lines, which can match the lines on the outer wall of the bottle cap to further ensure the stability of the clamping activity.

[0043] The working process of the utility model is as follows: when the bottle cap moves to the bottom of the device, the driving source drives the entire device to move to the corresponding position, and by applying a certain pressure to the pressing block 6, the drop rod 3 can be lowered, and the fixed rack 14 can rotate the rotating gear 15, and then the rotating disk 8 can be smoothly rotated through a series of transmissions. The rotation of the rotating disk 8 can make the moving rack 10 move on the spiral groove 13, and then the three moving racks 10 move synchronously away from the center of the circle, so that space for accommodating the bottle cap is leaked between the three clamping devices 2.

[0044] When the bottle cap is between the three clamping devices 2, the applied force is cancelled, and the drop rod 3 rises under the action of the return spring 4, and then the three moving racks 10 move synchronously toward the center of the circle. The inner wall of the clamping plate 12 has a certain elasticity, so the bottle cap can be clamped smoothly.

[0045] Then the whole device moves to the top of the bottle body, then the bottle cap is put in the appropriate position, and then the whole device is rotated to complete the installation of the bottle cap.

[0046] The space for placing the bottle caps between the three clamping devices 2 is related to the moving distance of the clamping devices 2, and the moving distance of the clamping devices 2 is closely related to the number of rotations of the transmission gear 9, and the number of rotations of the transmission gear 9 is related to the falling distance of the drop rod 3. Therefore, by controlling the falling distance of the drop rod 3, the device can be suitable for bottle caps of different sizes, and is more applicable.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
