Description

Technical Field

[0001] The utility model relates to an assembly technology of a bottle cap and a bottle mouth, and more specifically, to a capping mechanism of a filling device. Background Art

[0002] In the filling industry, bottle filling is a very common method. In the production of bottle filling, capping is an indispensable part. In the current technology, capping mostly uses guide grooves to convey bottle caps. When the bottle is transferred to the bottom of the bottle cap, the bottle cap is scraped down to the bottle mouth. This form requires that the bottle cap can be placed on the bottle mouth relatively stably after being scraped down to the bottle mouth, which has high requirements for the bottle cap; for small bottle caps or bottle caps that cannot be scraped, vacuum suction capping is mostly used. This method has high requirements for the relative positioning accuracy of the bottle mouth and the bottle cap, and an additional positioning mechanism is required to ensure the success rate of capping. The structure is relatively complex or the cost is high. For some special shaped bottle caps, or equipment with poor relative accuracy between the bottle mouth and the bottle cap, these capping methods are mostly not applicable, or cannot guarantee a good success rate.

[0003] For example: Chinese patent announcement number CN105366608A, announcement date March 2, 2016, invention name is a bottle cap stamping pre-rotation positioning mechanism, the application discloses a bottle cap and bottle mouth assembly mechanism, including a bottle cap positioning block, a pre-rotation capping assembly, a capping power assembly and a bottle positioning block, the pre-rotation capping assembly is slidably connected to the bottle cap positioning block through a linear slide rail, the capping power assembly is fixed on the bottle cap positioning block, and the power output end is connected to the upper part of the pre-rotation capping assembly; this scheme can realize capping and preliminary capping at the same time, but the positioning method is complicated and the positioning accuracy is low. When the bottle cap enters the bottle cap flow inlet, the accurate positioning of the bottle mouth and the bottle cap cannot be guaranteed. Utility Model Content

[0004] The utility model overcomes the problems of complex positioning method and low positioning accuracy of bottle cap and bottle mouth in the existing bottle cap and bottle mouth assembly technology, and provides a capping mechanism for filling equipment. The solution coaxially arranges the bottle mouth positioning part and the bottle cap positioning part on the same clamping block, thereby improving the positioning accuracy of the bottle cap and the bottle mouth, and the positioning method is simple and the positioning accuracy is high.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a capping mechanism of a filling device, comprising a first capping clamping block and a second capping clamping block, wherein the first capping clamping block and the second capping clamping block are both provided with a cap-pushing notch and a bottle-clamping notch, wherein the cap-pushing notch and the bottle-clamping notch are coaxially arranged, and the radial dimension of the cap-pushing notch is greater than the radial dimension of the bottle-clamping notch. In this solution, the cap-pushing notch is used to push the bottle cap and position the bottle cap at the same time, and the bottle-clamping notch is used to position the bottle mouth or the bottle body. The cap-pushing notch and the bottle-clamping notch are arranged on the same cap-pushing clamping block, which greatly reduces the complexity of the structure, and the cap-pushing notch and the bottle-clamping notch are coaxially arranged, which improves the coaxiality of the bottle cap and the bottle mouth, thereby improving the positioning and assembly efficiency of both. The cap-pushing notch and the bottle-clamping notch on the two clamping blocks can form a ring when docked, thereby clamping the bottle cap and the bottle mouth.

[0006] Preferably, a mounting seat is further included, wherein a slide groove is provided on the mounting seat, and the two ends of the slide groove are respectively slidably connected to the first punching and capping clamping block and the second punching and capping clamping block.

[0007] Preferably, a driving device slot is further provided at both ends of the slide, and a driving device is provided in the two driving device slots, and the driving device connects the first punching and covering clamping block and the second punching and covering clamping block.

[0008] Preferably, a bottle cap guide groove is provided on one side of the chute. The bottle cap guide groove is used to transport the bottle caps into the chute, so it is necessary to open a guide groove on the side of the chute.

[0009] Preferably, the sliding distance of the first capping clamp is greater than the sliding distance of the second capping clamp. In a capping cycle, the sliding distance of the first capping clamp is longer than that of the second capping clamp, so that the position of the bottle cap guide groove and the position of the bottle cap punching can be staggered, on the one hand, to prevent the bottle cap guide groove and the bottle cap punching from being at the same position, affecting the bottle cap conveying at the bottle cap guide groove; on the other hand, the second capping clamp can be in place in advance, and the position of the bottle cap can be pre-positioned to improve the positioning accuracy.

[0010] Preferably, the bottom of the bottle cap guide groove is a bottle cap conveying plate, and the bottle cap conveying plate extends into the chute. The bottle cap conveying plate is located at the bottom of the bottle cap guide groove, and plays a role in conveying and supporting the bottle caps.

DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0024] Example 1: Figures 1 to 4 The capping mechanism of a filling device shown comprises a mounting seat 5, a supporting column is arranged at the bottom of the mounting seat 5, so that the capping mechanism can adapt to the supply position of the bottle cap 16 and the bottle body 15 of the filling device.

[0025] The mounting seat 5 is in the shape of an elongated strip as a whole, and a slide groove 6 structure is provided on the top of the mounting seat 5. There is a square driving device groove 7 at each end of the slide groove 6. The radial dimension of the driving device groove 7 is slightly larger than the groove width of the slide groove 6. A driving device 8 is placed in the driving device groove 7. The driving device can adopt a servo motor or a common driving structure such as a cylinder structure. In this embodiment, the driving device adopts a telescopic cylinder, including a first cylinder 8.1 and a second cylinder 8.2. The shapes of the first cylinder 8.1 and the second cylinder 8.2 are adapted to the driving device groove 7. When the first cylinder 8.1 and the second cylinder 8.2 are assembled, the driving device groove 7 can play a good positioning role for the first cylinder 8.1 and the second cylinder 8.2.

[0026] The driving device is connected to the punch cover clamp block assembly in the slide groove 6, the telescopic end of the first cylinder 8.1 is connected to the first punch cover clamp block 1 through a telescopic rod, and the telescopic end of the second cylinder 8.2 is connected to the second punch cover clamp block 2 through a telescopic rod. The first punch cover clamp block 1 and the second punch cover clamp block 2 are both arranged in the slide groove 6, and the first punch cover clamp block 1 and the second punch cover clamp block 2 are both slidably connected to the slide groove 6.

[0027] The first capping clamping block 1 and the second capping clamping block 2 are both provided with a cap pushing notch 3 and a bottle clamping notch 4, and the position of the cap pushing notch 3 is located above the bottle clamping notch 4, and the groove surfaces of the cap pushing notch 3 and the bottle clamping notch 4 are both arc-shaped, and the cap pushing notch 3 and the bottle clamping notch 4 are also arranged in the same axis direction to ensure the coaxiality of the bottle cap 16 and the bottle body 15 during stamping. The cap pushing notches 3 on the first capping clamping block 1 and the second capping clamping block 2 are arranged facing each other, and when the first cylinder 8.1 and the second cylinder 8.2 respectively drive the first capping clamping block 1 and the second capping clamping block 2 to move towards each other, the cap pushing notch 3 and the bottle clamping notch 4 on the first capping clamping block 1 can respectively form a cylindrical cavity with the cap pushing notch 3 and the bottle clamping notch 4 on the second capping clamping block 2, which plays a role in clamping and positioning the bottle cap 16 and the bottle body 15.

[0028] It should be noted that, since the bottle cap 16 is matched with the bottle mouth of the bottle body 15, the radial dimension of the bottle cap 16 is slightly larger than the radial dimension of the bottle mouth (or bottle neck), so the radial dimension of the push cap notch 3 on the first cap punching clamping block 1 needs to be slightly larger than the dimension of the bottle clamping notch 4. In this way, when the first cap punching clamping block 1 and the second cap punching clamping block 2 are matched, the bottle cap 16 and the bottle neck can be clamped at the same time, thereby improving the success rate of the assembly of the bottle cap 16 and the bottle mouth.

[0029] A bottle cap guide groove 9 is also provided in the length direction of the slide groove 6. The bottle cap guide groove 9 is arranged in the middle position of the slide groove 6. The bottle cap guide groove 9 is located on the upper surface of the mounting seat 5. The bottom of the bottle cap guide groove 9 is a bottle cap conveying plate 10. The bottle cap conveying plate 10 supports and conveys the bottle caps 16.

[0030] One end of the bottle cap conveying plate 10 is connected to the bottle cap conveying device (not shown in the figure), and the other end extends into the slide groove 6, and the bottle cap conveying plate 10 still has a certain length in the length direction of the slide groove 6, and is greater than the groove width of the bottle cap guide groove 9. Therefore, in order to facilitate the movement of the cap punching clamp block assembly and prevent the bottle cap conveying plate 10 from hindering the movement of the first cap punching clamp block 1 and the second cap punching clamp block 2, in this embodiment, only one hollow groove 11 is provided on the first cap punching clamp block 1, the position of the hollow groove 11 corresponds to the position of the bottle cap conveying plate 10, and the length of the hollow groove 11 in the direction of the slide groove 6 is not less than the length of the bottle cap conveying plate 10 in the direction of the slide groove; when the first cap punching clamp block 1 and the second cap punching clamp block 2 cooperate, one end of the bottle cap conveying plate 10 in the slide groove 6 abuts against the hollow groove 11 or leaves a certain gap, and the other end is just flush with the cylindrical cavity formed by the push cap notch 3, and the bottle cap conveying plate 10 at this end is an arc surface consistent with the push cap notch 3, so that the bottle cap 16 can smoothly move to the position of the bottle mouth during the stamping process.

[0031] When the length of the hollow groove 11 in the direction of the slide groove 6 is equal to the length of the bottle cap conveying plate 10 in the direction of the slide groove 6, the bottle cap conveying plate 10 can limit the first capping clamping block 1 to prevent the first capping clamping block 1 from moving too far inside the slide groove 6; at the same time, the bottle cap conveying plate 10 can also support and guide the first capping clamping block 1, so that the first capping clamping block 1 is more stable during the movement; and when the length of the hollow groove 11 in the direction of the slide groove 6 is greater than the length of the bottle cap conveying plate 10 in the direction of the slide groove 6 When the length of the hollow groove 11 in the direction of the slide groove 6 is less than the length of the bottle cap conveying plate 10 in the direction of the slide groove 6, the push cap notch 3 on the first cap punching clamping block 1 can never be aligned with the arcuate end on the bottle cap conveying plate 10, that is, the bottle cap 16 cannot be clamped.

[0032] Due to the presence of the hollow groove 11 and the bottle cap conveying plate 10, the push cover notch 3 on the first punching clamp 1 is divided into an upper push cover notch and a lower push cover notch, and rounded transitions are also provided at the ends of the upper push cover notch and the lower push cover notch. On the one hand, the stress concentration at the push cover notch 3 is reduced, and on the other hand, the transition section between the upper push cover notch and the lower push cover notch can guide the bottle cap 16 to prevent the bottle cap 16 from being stuck during the punching process.

[0033] In addition, the telescopic length of the first cylinder 8.1 is greater than the telescopic length of the second cylinder 8.2, so that the movement distance of the first capping clamp 1 is greater than the movement distance of the second capping clamp 2, and the positioning position of the bottle mouth and the bottle cap 16 is also staggered with the position of the bottle cap guide groove 9. On the one hand, it prevents the bottle cap guide groove 9 and the bottle cap 16 from being stamped at the same position, affecting the conveyance of the bottle cap 16 at the bottle cap guide groove 9; on the other hand, the second capping clamp 2 can be in place in advance, and the position of the bottle cap 16 can be pre-positioned first, thereby improving the positioning accuracy.

[0034] A punching mechanism is also provided above the position where the bottle body 15 and the bottle cap 16 are clamped and positioned. The punching mechanism 14 comprises a third cylinder 14.2 and a punching head 14.1. The punching head 14.1 is connected to the telescopic rod of the third cylinder 14.2. When the first punching clamp 1 and the second punching clamp 2 clamp the bottle cap 16 and the bottle body 15, the third cylinder 14.2 will drive the punching head 14.1 downward to punch the bottle cap 16 so that the bottle cap 16 is pressed into the bottle mouth, thereby completing the assembly operation of the bottle cap 16 and the bottle mouth.

[0035] Example 2: Figures 1 to 6The capping mechanism of a filling device shown comprises a mounting seat 5, a supporting column is arranged at the bottom of the mounting seat 5, so that the capping mechanism can adapt to the supply position of the bottle cap 16 and the bottle body 15 of the filling device.

[0036] The mounting seat 5 is in the shape of an elongated strip as a whole, and a slide groove 6 structure is provided on the top of the mounting seat 5. There is a square driving device groove 7 at each end of the slide groove 6. The radial dimension of the driving device groove 7 is slightly larger than the groove width of the slide groove 6. A driving device 8 is placed in the driving device groove 7. The driving device can adopt a servo motor or a common driving structure such as a cylinder structure. In this embodiment, the driving device adopts a telescopic cylinder, including a first cylinder 8.1 and a second cylinder 8.2. The shapes of the first cylinder 8.1 and the second cylinder 8.2 are adapted to the driving device groove 7. When the first cylinder 8.1 and the second cylinder 8.2 are assembled, the driving device groove 7 can play a good positioning role for the first cylinder 8.1 and the second cylinder 8.2.

[0037] The driving device is connected to the punch cover clamp block assembly in the slide groove 6, the telescopic end of the first cylinder 8.1 is connected to the first punch cover clamp block 1 through a telescopic rod, and the telescopic end of the second cylinder 8.2 is connected to the second punch cover clamp block 2 through a telescopic rod. The first punch cover clamp block 1 and the second punch cover clamp block 2 are both arranged in the slide groove 6, and the first punch cover clamp block 1 and the second punch cover clamp block 2 are both slidably connected to the slide groove 6.

[0038] The first capping clamping block 1 and the second capping clamping block 2 are both provided with a cap pushing notch 3 and a bottle clamping notch 4, and the position of the cap pushing notch 3 is located above the bottle clamping notch 4, and the groove surfaces of the cap pushing notch 3 and the bottle clamping notch 4 are both arc-shaped, and the cap pushing notch 3 and the bottle clamping notch 4 are also arranged in the same axis direction to ensure the coaxiality of the bottle cap 16 and the bottle body 15 during stamping. The cap pushing notches 3 on the first capping clamping block 1 and the second capping clamping block 2 are arranged facing each other, and when the first cylinder 8.1 and the second cylinder 8.2 respectively drive the first capping clamping block 1 and the second capping clamping block 2 to move towards each other, the cap pushing notch 3 and the bottle clamping notch 4 on the first capping clamping block 1 can respectively form a cylindrical cavity with the cap pushing notch 3 and the bottle clamping notch 4 on the second capping clamping block 2, which plays a role in clamping and positioning the bottle cap 16 and the bottle body 15.

[0039] It should be noted that, since the bottle cap 16 is matched with the bottle mouth of the bottle body 15, the radial dimension of the bottle cap 16 is slightly larger than the radial dimension of the bottle mouth (or bottle neck), so the radial dimension of the push cap notch 3 on the first cap punching clamping block 1 needs to be slightly larger than the dimension of the bottle clamping notch 4. In this way, when the first cap punching clamping block 1 and the second cap punching clamping block 2 are matched, the bottle cap 16 and the bottle neck can be clamped at the same time, thereby improving the success rate of the assembly of the bottle cap 16 and the bottle mouth.

[0040] A bottle cap guide groove 9 is also provided in the length direction of the slide groove 6. The bottle cap guide groove 9 is arranged in the middle position of the slide groove 6. The bottle cap guide groove 9 is located on the upper surface of the mounting seat 5. The bottom of the bottle cap guide groove 9 is a bottle cap conveying plate 10. The bottle cap conveying plate 10 supports and conveys the bottle caps 16.

[0041] One end of the bottle cap conveying plate 10 is connected to the bottle cap conveying device (not shown in the figure), and the other end extends into the slide groove 6, and the bottle cap conveying plate 10 still has a certain length in the length direction of the slide groove 6, and is greater than the groove width of the bottle cap guide groove 9. Therefore, in order to facilitate the movement of the cap punching clamp block assembly and prevent the bottle cap conveying plate 10 from hindering the movement of the first cap punching clamp block 1 and the second cap punching clamp block 2, in this embodiment, only one hollow groove 11 is provided on the first cap punching clamp block 1, the position of the hollow groove 11 corresponds to the position of the bottle cap conveying plate 10, and the length of the hollow groove 11 in the direction of the slide groove 6 is not less than the length of the bottle cap conveying plate 10 in the direction of the slide groove; when the first cap punching clamp block 1 and the second cap punching clamp block 2 cooperate, one end of the bottle cap conveying plate 10 in the slide groove 6 abuts against the hollow groove 11 or leaves a certain gap, and the other end is just flush with the cylindrical cavity formed by the push cap notch 3, and the bottle cap conveying plate 10 at this end is an arc surface consistent with the push cap notch 3, so that the bottle cap 16 can smoothly move to the position of the bottle mouth during the stamping process.

[0042] When the length of the hollow groove 11 in the direction of the slide groove 6 is equal to the length of the bottle cap conveying plate 10 in the direction of the slide groove 6, the bottle cap conveying plate 10 can limit the first capping clamping block 1 to prevent the first capping clamping block 1 from moving too far inside the slide groove 6; at the same time, the bottle cap conveying plate 10 can also support and guide the first capping clamping block 1, so that the first capping clamping block 1 is more stable during the movement; and when the length of the hollow groove 11 in the direction of the slide groove 6 is greater than the length of the bottle cap conveying plate 10 in the direction of the slide groove 6 When the length of the hollow groove 11 in the direction of the slide groove 6 is less than the length of the bottle cap conveying plate 10 in the direction of the slide groove 6, the push cap notch 3 on the first cap punching clamping block 1 can never be aligned with the arcuate end on the bottle cap conveying plate 10, that is, the bottle cap 16 cannot be clamped.

[0043] Due to the presence of the hollow groove 11 and the bottle cap conveying plate 10, the push cover notch 3 on the first punching clamp 1 is divided into an upper push cover notch and a lower push cover notch, and rounded transitions are also provided at the ends of the upper push cover notch and the lower push cover notch. On the one hand, the stress concentration at the push cover notch 3 is reduced, and on the other hand, the transition section between the upper push cover notch and the lower push cover notch can guide the bottle cap 16 to prevent the bottle cap 16 from being stuck during the punching process.

[0044] In addition, the telescopic length of the first cylinder 8.1 is greater than the telescopic length of the second cylinder 8.2, so that the movement distance of the first capping clamp 1 is greater than the movement distance of the second capping clamp 2, and the positioning position of the bottle mouth and the bottle cap 16 is also staggered with the position of the bottle cap guide groove 9. On the one hand, it prevents the bottle cap guide groove 9 and the bottle cap 16 from being stamped at the same position, affecting the conveyance of the bottle cap 16 at the bottle cap guide groove 9; on the other hand, the second capping clamp 2 can be in place in advance, and the position of the bottle cap 16 can be pre-positioned first, thereby improving the positioning accuracy.

[0045] A limiting structure 12 is also provided on the first punching and covering clamping block 1 and the second punching and covering clamping block 2, and a limiting structure 12 is also provided on the slide 6. The limiting structure 12 on the slide 6 cooperates with the limiting structure 12 on the punching and covering clamping block assembly to limit the punching and covering clamping block assembly. Figure 4 and Figure 5 As shown, on the first punch cover clamping block 1, the width of the upper push cover slot is smaller than the width of the lower push cover slot, so that a first limiting step 12.1 is formed at the end of the upper push cover slot away from the push cover slot 3, and a second limiting step 12.2 is also provided at the corresponding position on the slide groove 6. The first limiting step 12.1 on the first punch cover clamping block 1 and the second limiting step 12.2 in the slide groove 6 will limit the first punch cover clamping block 1 when the first punch cover clamping block 1 moves to the limit position; similarly, the same limiting structure 12 is also provided on the second punch cover clamping block 1 and the corresponding slide groove 6 position.

[0046] In order to prevent dirt from falling onto the bottle cap 16 in the bottle cap guide groove 9 and affecting the stamping operation of the bottle cap 16, a guide groove cover plate 13 is further provided above the bottle cap guide groove 9. Figure 6 As shown, the guide groove cover plate 13 is placed on the upper surface of the mounting seat 5 , and because the positioning and stamping positions of the bottle cap guide groove 9 and the bottle cap 16 are staggered, the guide groove cover plate 13 will not interfere with the stamping operation of the bottle cap 16 .

[0047] A projection 13.1 is also provided on the guide slot cover plate 13, and the projection 13.1 faces downward and is located in the slide slot 6, which can prevent the position of the guide slot cover plate 13 from changing at will. In order to prevent the projection 13.1 from affecting the movement of the punch cover clamp block assembly, the depth of the slide slot 6 needs to be greater than the height of the punch cover clamp block assembly, and a certain space is reserved for the projection 13.1 to avoid the movement of the first punch cover clamp block 1 and the second punch cover clamp block 2.

[0048] A punching mechanism is also provided above the position where the bottle body 15 and the bottle cap 16 are clamped and positioned. The punching mechanism 14 comprises a third cylinder 14.2 and a punching head 14.1. The punching head 14.1 is connected to the telescopic rod of the third cylinder 14.2. When the first punching clamp 1 and the second punching clamp 2 clamp the bottle cap 16 and the bottle body 15, the third cylinder 14.2 will drive the punching head 14.1 downward to punch the bottle cap 16 so that the bottle cap 16 is pressed into the bottle mouth, thereby completing the assembly operation of the bottle cap 16 and the bottle mouth.
