Description

Technical Field

[0001] This invention belongs to the field of dairy product packaging technology, and in particular relates to a capping machine. Background Technology

[0002] The dairy industry has developed rapidly over the past few decades, with increasing market demand prompting dairy producers to continuously improve production efficiency and capacity. As a food product, the quality and safety of dairy products are of paramount importance. In the dairy production process, the airtightness and hygiene of packaging are crucial to ensuring product quality. Capping machines, as essential equipment in dairy packaging, must possess excellent sealing performance and hygienic conditions to guarantee the quality and safety of dairy products. Therefore, capping is necessary during the production process of dairy product pouches.

[0003] In the current process of capping dairy product packets, there are problems affecting the quality of capping. Specifically, during this crucial step, the cap often fails to move accurately to the top of the dairy product packet according to the predetermined path and position. This results in misalignment of the cap, leading to asymmetry in appearance and affecting the overall aesthetics of the product. Alternatively, the edge of the cap may not fit tightly against the seal of the dairy product packet, leaving gaps. This not only compromises the airtightness of the packaging, potentially allowing the dairy product to be contaminated by external factors, affecting product quality and shelf life, but also, during subsequent transportation and storage, factors such as vibration may further amplify this fitting error, even leading to more serious problems such as the cap loosening or falling off.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0033] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Reference Figures 1 to 12 As shown, this embodiment of the invention provides a capping machine, including a machine frame 1. The machine frame 1 is provided with a cap feeding and conveying mechanism 2, a reciprocating cap pushing mechanism 3, a dispensing mechanism 4, a cap gripping and pressing mechanism 5, and a dairy product package conveying mechanism 6. The cap feeding and conveying mechanism 2 is horizontally arranged. The reciprocating cap pushing mechanism 3 is located beside the cap feeding and conveying mechanism 2 and is connected to the cap feeding and conveying mechanism 2. The dispensing mechanism 4 is located beside the reciprocating cap pushing mechanism 3. The cap gripping and pressing mechanism 5 is located below the reciprocating cap pushing mechanism 3 and the dispensing mechanism 4 and is used to move the cap position. The dairy product package conveying mechanism 6 is located below the cap gripping and pressing mechanism 5.

[0035] Work steps:

[0036] Step 1: After the cap sorting machine sorts the caps, they enter the cap feeding conveyor 2;

[0037] Step 2: The cap is moved to the side of the reciprocating cap pushing mechanism 3 by the cap feeding mechanism 2;

[0038] Step 3: The reciprocating cover-pushing mechanism 3 operates to deliver the cover to the designated glue application point;

[0039] Step 4: After the glue has been applied to the cap, the reciprocating cap-pushing mechanism 3 will send the cap to the designated cap-removing position and simultaneously send the next cap to the glue-application position.

[0040] Step 5: The cap-grabbing and pressing mechanism 5 slides on the upper trapezoidal plate 511 to rise to the cap-removing position, thus completing the cap removal.

[0041] Step 6: The cap-grabbing and capping mechanism 5 operates to attach the cap with applied adhesive to the designated position on the dairy product package;

[0042] Step 7 is maintained for a period of time, and the dairy product package with the lid affixed is sent out of the machine through the dairy product package conveying mechanism 6.

[0043] Specifically, the cap conveying mechanism 2 includes a horizontal conveyor frame 21, a limiting frame seat 22, and a horizontal conveyor belt 23. The horizontal conveyor frame 21 is located inside the machine frame 1. The limiting frame seat 22 is horizontally arranged on top of the horizontal conveyor frame 21. The horizontal conveyor belt 23 is located on the horizontal conveyor frame 21 and below the limiting frame seat 22. The limiting frame seat 22 is provided with a limiting groove 24. The horizontal conveyor frame 21 is provided with a conveying groove 25 at the middle position.

[0044] After the arranged bottle caps are placed in the limiting grooves 24 on the limiting frame 22, the horizontal conveyor belt 23 drives the bottle caps to move forward at the position of the limiting grooves 24, and transfers the bottle caps to the conveying grooves 25 on the horizontal conveyor frame 21 in order to push the bottle caps to the subsequent dispensing work.

[0045] Specifically, the reciprocating push cover mechanism 3 includes a push cover seat 30, a slide rail 31, a reciprocating motor 32, a first reciprocating plate 33, a second reciprocating plate 34, a reciprocating block 35, and two reciprocating clamping plates 36. The push cover seat 30 is located beside the horizontal conveyor frame 21. The reciprocating motor 32 is located at the top of the push cover seat 30. The slide rail 31 is horizontally arranged at the bottom of the push cover seat 30. The reciprocating block 35 is slidably connected to the slide rail 31. One end of the first reciprocating plate 33 is located on the main shaft of the reciprocating motor 32. The two ends of the second reciprocating plate 34 are respectively hinged to the other end of the first reciprocating plate 33 and the reciprocating block 35. The two reciprocating clamping plates 36 are symmetrically arranged at both ends of the reciprocating block 35 and move on both sides of the conveying groove 25.

[0046] When the bottle cap is moved, the reciprocating motor 32 drives the first reciprocating plate 33 to rotate, which in turn drives the second reciprocating plate 34 to rotate, thereby causing the slider to move horizontally on the slide rail 31. The horizontal movement of the slider can drive the two reciprocating clamps 36 to move horizontally back and forth, intermittently conveying the bottle cap in the conveying groove 25 forward to the subsequent dispensing position on the upper mounting seat 501, so that the bottle cap can be dispensed laterally. The reciprocating push cap mechanism 3 can achieve precise movement of the bottle cap, so that the bottle cap will move precisely into the bottle cap groove 506 to fix the bottle cap to be conveyed.

[0047] Specifically, the dispensing mechanism 4 includes a dispensing base 40, a drive motor 41, an eccentric wheel 42, a slide rail 43, a drive plate 45, and an automatic dispensing head 46. The dispensing base 40 is located on the horizontal machine frame 1. The drive motor 41 is vertically mounted on the dispensing base 40. The eccentric wheel 42 is connected to the main shaft of the drive motor 41. An eccentric shaft 47 is provided on the eccentric wheel 42. The slide rail 43 is horizontally mounted on the dispensing base 40. A slide rail block 44 is provided on the slide rail 43 to cooperate with the slide rail 43. The slide rail block 44 is rotatably connected to the drive plate 45. One end of the drive plate 45 is provided with a drive groove 48 that slides with the eccentric shaft 47. The automatic dispensing head 46 is vertically mounted on the other end of the drive plate 45.

[0048] During the dispensing process on the bottle cap, the drive motor 41 drives the eccentric wheel 42 to rotate, which in turn drives the eccentric wheel 42 to rotate in the drive groove 48 on the drive plate 45. This causes the drive plate 45 to rotate on the slide block 44, and also causes the slide block 44 to move horizontally on the slide 43. This causes the position of the automatic dispensing head 46 on the other end of the drive plate 45 to swing, so that the automatic dispensing head 46 swings in a circle on the bottle cap, automatically dispensing glue onto the bottle cap.

[0049] Specifically, the cap-gripping and capping mechanism 5 includes a mounting frame 51, a rotating motor 52, a first drive sprocket set 53, a second drive sprocket set 54, several mounting brackets 55, and several cap-gripping components 50. The mounting frame 51 is mounted on the frame 1. The first drive sprocket set 53 and the second drive sprocket set 54 are symmetrically rotatably connected to the mounting frame 51. The rotating motor 52 is located on the mounting frame 51 and is connected to the first drive sprocket set 53. Two chains 56 are sleeved on the first drive sprocket set 53 and the second drive sprocket set 54. Several mounting brackets 55 are connected to the two chains 56 at equal intervals. The cap-gripping components 50 are located on the mounting brackets 55.

[0050] When gripping and pressing the bottle cap, the rotating motor 52 drives the first drive sprocket group 53 and the second drive sprocket group 54 to rotate on the mounting frame 51, which in turn drives the two chains 56 to rotate, thereby driving several mounting frames 55 to rotate, and driving several bottle cap gripping parts 50 to rotate, thus achieving the gripping and pressing of the bottle cap, and thus attaching the bottle cap to the dairy product package.

[0051] Specifically, the bottle cap clamping component 50 includes an upper mounting base 501, a lower mounting base 502, and two sliding rods 503. The upper mounting base 501 and the lower mounting base 502 are respectively disposed at the two ends of the two sliding rods 503. The two sliding rods 503 are slidably connected to the end position of the mounting frame 55. A first return spring 504 is provided between the lower mounting base 502 and the mounting frame 55. A rotating wheel 505 is provided on the lower mounting base 502. A bottle cap groove 506 is provided on the upper mounting base 501. A rotating shaft 507 is rotatably connected on the upper mounting base 501. A limiting frame 508 is provided on one end of the rotating shaft 507. A limiting wheel 509 is rotatably connected on the limiting frame 508. A second return spring 500 connected to the upper mounting base 501 is provided at the other end of the rotating shaft 507.

[0052] The mounting frame 51 has an upper trapezoidal plate 511 on its side wall, which is located above the automatic dispensing head 46. The rotating wheel 505 rotates on the upper trapezoidal plate 511. The bottom of the horizontal conveyor frame 21 has a limiting inclined block 512 for the limiting wheel 509 to rotate. The mounting frame 51 has a sliding plate 513 for the rotating wheel 505 to slide on its side wall. The end of the sliding plate 513 has a lower trapezoidal plate 514, and the limiting wheel rotates on the lower trapezoidal plate 514.

[0053] During the capping and capping process, the rotation of the two chains 56 drives the mounting frame 55 to rotate, thereby moving the rotating wheel 505 on the lower mounting base 502 to the position of the upper trapezoidal plate 511. This causes the two sliding rods 503 to slide on the mounting frame 55, thereby moving the lower mounting base 502 upward and moving the upper mounting base 501 below the conveying trough 25. During the upward movement and forward movement via the chains 56, the limiting wheel 509 and the limiting inclined block 512 on the limiting frame 508... When contact is made, the limiting frame 508 rotates on the upper mounting base 501 via the rotating shaft 507, thereby opening the bottle cap groove 506 on the upper mounting base 501. This allows the bottle cap to move into the bottle cap groove 506 via the positions of the two reciprocating clamps 36 in the conveying groove 25. After that, the mounting frame 55 continues to move forward, and the limiting wheel 509 moves out from the limiting inclined block 512. Then, through the reset of the second reset spring 500, the limiting frame 508 rotates via the rotating shaft 507, limiting the bottle cap in the bottle cap groove 506.

[0054] Then, the mounting bracket 55 continues to move forward. The reset spring 504 resets the two slide bars 503, causing them to move on the mounting bracket 55. This moves the rotating wheel 505 on the lower mounting base 502 to rotate with the other inclined side of the upper trapezoidal plate 511. After the chain 56 rotates, the lower mounting base 502 is rotated to the top. At this time, the rotating wheel 505 on the lower mounting base 502 slides at the bottom of the sliding plate 513. When it moves to the position of the lower trapezoidal plate 514, the limiting wheel 509 rotates on the lower trapezoidal plate 514, thereby driving the limiting bracket 508 to rotate on the upper mounting base 501 through the rotating shaft 507. This moves the bottle cap down from the bottle cap groove 506 and presses it onto the dairy product bag, thus attaching the bottle cap to the dairy product bag.

[0055] Specifically, the dairy product package conveying mechanism 6 includes a first conveying motor 60, a first conveying frame 61, and two sets of conveying components. The first conveying motor 60 is located on the first conveying frame 61, and the two sets of conveying components are symmetrically arranged on the first conveying frame 61. Each conveying component includes a conveying bracket 62 arranged on the first conveying frame 61. Each end of the conveying bracket 62 has two rotatably connected conveying wheels 63. A first conveyor belt 64 is sleeved between the two conveying wheels 63. The first conveying motor 60 is connected to the conveying wheels 63 by transmission.

[0056] During the conveying process of the dairy product package, the dairy product package is placed between two first conveyor belts 64. The first conveyor motor 60 drives the two conveyor wheels 63 on the two sets of conveyor components to rotate on the conveyor support 62, which in turn drives the corresponding two first conveyor belts 64 to rotate, thus moving the position of the dairy product package forward so that the bottle cap can be attached to the dairy product package later.

[0057] Specifically, the dairy product package conveying mechanism 6 further includes conveying components symmetrically spaced on both sides of the first conveying frame 61. The conveying components include a conveying frame 65, a conveying motor 66, two upper conveying wheels 67, and two lower conveying wheels 68. The two upper conveying wheels 67 are symmetrically rotatably connected to the upper position of the conveying frame 65, and an upper conveying belt 69 is sleeved between the two upper conveying wheels 67. The upper conveying belt 69 is provided with upper conveying blocks 690 arranged at equal intervals. The two lower conveying wheels 68 are symmetrically rotatably connected to the lower position of the conveying frame 65, and a lower conveying belt 691 is sleeved between the two lower conveying wheels 68. The lower conveying belt 691 is provided with lower conveying blocks 692 arranged at equal intervals. The conveying motor 66 is located on the conveying frame 65, and the main shaft of the conveying motor 66 is connected to the upper conveying wheels 67 and the lower conveying wheels 68.

[0058] After the dairy product package is conveyed forward to the transfer frame 65 by the two first conveyor belts 64, the transfer motor 66 drives the corresponding upper transfer wheel 67 and lower transfer wheel 68 to rotate on the transfer frame 65. This drives the upper transfer belt 69 and lower transfer belt 691 to rotate, thereby moving the corresponding equally spaced upper transfer block 690 and lower transfer block 692. The dairy product package is moved forward within the gap between adjacent upper transfer block 690 and lower transfer block 692, so that the bottle cap can be attached to the dairy product package later.
