Description

Technical Field

[0001] This invention belongs to the field of bottle cap manufacturing technology, and in particular relates to a bottle cap anti-sticking device. Background Technology

[0002] This equipment is designed for a type of wine cap—a one-piece cap—which consists of 6 parts. This equipment involves 5 parts, see reference [link / reference needed]. Figure 2 , Figure 3 The cover includes a lower cover 101 and an upper cover. The upper cover is composed of an outer cover 104, an outer sleeve 102, an inner plug 105, and a middle sleeve 103; wherein the outer cover 104 and the middle sleeve 103 are threaded together.

[0003] Reference Figure 1 The current bottle cap production process is as follows: injection molding - final assembly - spray painting - disassembly of the upper and lower caps - processing the opening surface of the upper cap, then hot stamping the upper and lower caps separately, and finally assembling the upper and lower caps.

[0004] Due to process requirements, the injection-molded parts need to be painted after assembly. During painting, the opening surfaces 106 of the outer cover 104 and the outer sleeve 102 are stuck together by the paint, causing the outer cover 104 to be unable to be unscrewed normally. Therefore, it is necessary to process the opening surfaces 106.

[0005] During spray painting, the carrier of the spraying equipment contains dry paint particles and dust, which will enter the sealing cavity of the inner plug 105. Its structure makes it difficult to form airflow, but since the sealing cavity of the inner plug 105 is in direct contact with the wine, it must be cleaned and dusted.

[0006] Secondly, when the cap 10 is placed on the carrier of the spraying equipment during painting, the shaking causes some of the inner plugs 105 to loosen, which can easily lead to leakage of the wine later. Therefore, it is necessary to calibrate the installation position of the inner plugs 105.

[0007] This equipment is used in an intermediate process to disassemble the upper and lower covers for hot stamping in the next process. Summary of the Invention

[0008] In view of the technical problems existing in the background art, the present invention provides a bottle cap anti-sticking device.

[0009] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0010] A bottle cap anti-sticking device,

[0011] The mechanism includes a surface-opening treatment mechanism, which comprises a base plate at a fixed inclined angle, an ejector cylinder, a rotating fixture, and a clamping mechanism.

[0012] The base plate is provided with a second guide chute for transporting the top cover. On both sides of the second guide chute are respectively provided an ejector cylinder and a rotating fixture. The ejector cylinder and the ejector fixture are connected, and the ejector fixture is positioned directly opposite the rotating fixture. The clamping mechanism is provided on the line connecting the rotating fixture and the ejector fixture.

[0013] The ejector tool can extend into the guide groove 2 and push the upper cover towards the rotating tool so that the upper cover is tightly attached to the rotating tool, and the clamping mechanism is set directly opposite the opening surface of the upper cover; the clamping mechanism is used to squeeze the opening surface of the upper cover to open the gap so that the paint cracks.

[0014] The present invention has the following advantages and beneficial effects:

[0015] I. In this invention, by designing a disassembly mechanism, the integrated cover enters the neatly arranged material from the inlet of the guide chute, and the disassembly cylinder drives the disassembly tooling to be ejected; there is a U-shaped groove design at this position, because the lower cover is too large to pass through, so the upper and lower covers can be disassembled, thereby realizing the rapid disassembly of the upper and lower covers, providing support for the downstream hot stamping process of the upper and lower covers.

[0016] II. In this invention, by processing the opening mechanism, the disassembled top cover is neatly arranged and enters the guide groove two. The ejector tool extends into the guide groove two and pushes the top cover towards the rotating tool, causing the top cover to fit tightly against the rotating tool. Then, the clamping mechanism squeezes and opens the opening surface of the top cover, causing the paint to crack. After the clamping mechanism clamps and opens, the stepper motor controls the rotating tool and the top cover to rotate at a certain angle, and then the clamping mechanism clamps the top cover again. That is, through rotation at different angles, the opening surface of the top cover is clamped and squeezed from all directions, causing the opening surface to open and the paint to crack. After the opening surface is processed, the top cover enters the hot stamping process. This solves the technical problem that the opening surfaces of the outer cover and the outer sleeve are stuck together by paint during painting, making it impossible for the outer cover to be unscrewed.

[0017] Third, in this invention, an ejector tool is designed with airflow passing through it to clean the inner plug. At the same time, the ejector tool is designed to press the inner plug to correct, press, and calibrate its installation position. Furthermore, the ejector tool pressing the inner plug can prevent the inner plug from being dislodged due to the high-pressure cleaning gas passing through it. Attached Figure Description

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0040] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0041] Example 1

[0042] like Figures 4-9 As shown, the present invention provides a bottle cap anti-sticking device, which has three functions: first, to disassemble the upper cap and lower cap 101 of the cap 10; second, to process the opening surface 106 of the upper cap so that the paint on the opening surface 106 cracks; and third, to clean the inner plug 105 and correct the position of the inner plug 105.

[0043] The equipment includes a disassembly mechanism and a mechanism for processing the opening surface.

[0044] like Figure 4-9 As shown, the disassembly mechanism is used to disassemble the upper cover and lower cover 101 of the cover 10. The disassembly mechanism includes a guide trough 2, a partition 22, and a disassembly cylinder 4, which are inclined and fixed at a fixed angle on the base plate 11.

[0045] One side of the base plate 11 is mounted on the frame 1, and the other side is supported and fixed by the second support plate 25; one end of the guide chute 2 is mounted on the base plate 11, and its bottom is supported on the frame 1 by the first support plate 24.

[0046] The width of the guide trough 2 is approximately the same as the length of the cover 10, and the cover 10 can fit perfectly into the guide trough 2 (e.g., Figure 9 As shown, a top plate 21 is provided on the upper part of the guide trough 2. When the cover 10 is placed inside the guide trough 2, it can be limited by the top plate 21 to prevent it from falling out of the guide trough 2.

[0047] The guide trough 2 is used to transport the cover 10 (integral type). A decomposition cylinder 4 is arranged on one side of the partition 22. The decomposition cylinder 4 is fixed on the base plate 11 by the support 43. The decomposition cylinder 4 is connected to the decomposition tooling 41 by the floating joint 44. A guide sleeve 42 is provided on one side of the guide trough 2. The decomposition tooling 41 is slidably arranged in the guide sleeve 42.

[0048] A photoelectric sensor 23 is installed on the rear side of the guide trough 2. When the cover 10 enters from the inlet of the guide trough 2 and passes the photoelectric sensor 23, the decomposition cylinder 4 drives the decomposition tool 41 to be ejected.

[0049] like Figure 5 , Figure 8 , Figure 9As shown, the partition 22 is provided with a U-shaped limiting groove. The width of the limiting groove is exactly the same as the outer diameter of the outer cover 104 / outer cover 102, meaning that the outer cover 102 can be inserted into the limiting groove. The bottom section of the guide channel 2 is provided with a partition 22, which divides the guide channel 2 into two guide chambers. One guide chamber is connected to the guide channel 2, and the other guide chamber is connected to the lower cover outlet 12 provided on the bottom plate 11. The frame 1 is provided with a lower cover outlet 15, the upper end of which is directly opposite the lower cover outlet 12. When the cover 10 slides down along the guide channel 2, the lower cover 101 slides tightly against the partition 22, while the outer cover 102 is inserted into the limiting groove of the partition 22 to achieve limiting. Since the diameter of the lower cover 101 is larger than that of the outer cover 102, when the disassembly tooling 41 extends into the guide trough 2 through the guide hole 26 and into the inside of the cover 10, the ejector tooling 75 pushes against the outer cover 102 inside the cover 10, thereby pushing the upper cover to move as a whole. The lower cover 101 is limited and blocked by the partition 22, thus detaching and disassembling the lower cover 101 and the upper cover. After disassembly, the lower cover 101 is conveyed from the lower cover outlet 12, while the upper cover reaches the guide trough 2.

[0050] By designing a disassembly mechanism, the integrated cover enters the neatly arranged material from the inlet of the guide chute 2, and the disassembly cylinder 4 drives the disassembly tooling 41 to eject it. There is a U-shaped groove design at this position. Because the lower cover 101 is too large to pass through, the upper and lower covers can be disassembled, thereby realizing the rapid disassembly of the upper and lower covers and providing support for the downstream hot stamping process of the upper and lower covers 101.

[0051] Example 2

[0052] like Figure 4-9 As shown, the opening surface processing mechanism is used to press the opening surface 106 of the upper cover, thereby cracking the paint on the opening surface 106 so that the outer cover 104 can be unscrewed.

[0053] The mechanism for handling the opening surface includes a base plate 11 with a fixed inclined angle, an ejector cylinder 7, a rotating fixture 63, and a clamping mechanism. The base plate 11 has a second guide trough for transporting the top cover, which is connected to one side of the first guide trough 2. An ejector cylinder 7 and a rotating fixture 63 are respectively located on both sides of the second guide trough. The ejector cylinder 7 and the ejector fixture 75 are connected, with the ejector fixture 75 facing the rotating fixture 63. The clamping mechanism is located on the line connecting the rotating fixture 63 and the ejector fixture 75. The ejector fixture 75 can extend into the second guide trough and push the top cover towards the rotating fixture 63, causing the top cover to fit tightly against the rotating fixture 63. The clamping mechanism is positioned directly opposite the opening surface 106 of the top cover; the clamping mechanism is used to squeeze and open the gap of the opening surface 106 of the top cover, causing the paint to crack.

[0054] In this invention, a layer of silicone is provided on the end face of the rotating fixture 63, so that the silicone adheres tightly to the top cover and drives the top cover to rotate through the friction of the silicone. The silicone is relatively soft and will not damage the paint on the surface of the top cover.

[0055] like Figure 8 As shown, specifically, a side baffle 13 extends from one side of the base plate 11, and an L-shaped guide plate 5 is provided on the side baffle 13. The guide plate 5 and the interior of the side baffle 13 form a guide groove for conveying the lower cover 101. A guide hole 131 is provided on the side baffle 13, and a guide hole 51 corresponding to the guide hole 131 is provided on the side plate of the guide plate 5. The ejector tool 75 is positioned directly opposite the guide hole 51.

[0056] In this invention, as a preferred embodiment, two ejector fixtures 75 are provided, and correspondingly, the number and position of the guide holes 131 and the second guide hole 51 are set one-to-one. This allows for the processing of multiple top covers, ensuring efficiency.

[0057] like Figure 8-10 As shown, the ejector cylinder 7 is fixed to the base plate 11 via support 71, and is connected to the mounting base 72 via floating joint 76. Two ejector fixtures 75 are rotatably mounted on the mounting base 72 via bearing seats 754. Two sliders 73 are provided at the bottom of the mounting base 72, and two slide rails 74 are provided on the base plate 11. The sliders 73 slide on the slide rails 74, thus achieving precise guidance of the ejector fixtures 75. Two ejector fixtures 75 are positioned at a fixed distance on the mounting base 72. The number and position of the rotating fixtures 63 correspond one-to-one with the ejector fixtures 75, allowing multiple top covers to be processed simultaneously.

[0058] like Figure 4 , 17 As shown in Figure 18, the clamping mechanism is a finger cylinder 8 fixed on the side baffle 13, which has two relatively movable grippers 81. A fixed plate 6 is connected to the side baffle 13 via several connecting rods 64. A motor 61 is mounted on one side of the fixed plate 6, and a transmission box 62 is mounted on the other side. Preferably, belt drive is used. A rotating fixture 63 is rotatably mounted on the fixed plate 6. Each rotating fixture 63 has a synchronous pulley connected to its other side. The synchronous pulleys are connected by belts, and the stepper motor 61 drives the rotating fixture 63 to rotate via the synchronous pulleys. Alternatively, a gear-like transmission method can be used to drive the rotating fixture 63.

[0059] In this invention, by processing the opening mechanism, the disassembled top cover is neatly arranged and enters the guide groove two. The ejector fixture 75 extends into the guide groove two and pushes the top cover towards the rotating fixture 63, so that the top cover is tightly attached to the rotating fixture 63. Then, the finger cylinder 8 squeezes the opening surface 106 of the top cover to open the gap, thereby causing the paint to crack. After the finger cylinder 8 clamps and opens, the stepper motor 61 controls the rotating fixture 63 and the top cover to rotate at a certain angle, and then the finger cylinder 8 clamps the top cover again. That is, through rotation at different angles, the opening surface 106 of the top cover is rotated, clamped, and squeezed in all directions, thereby opening the gap of the opening surface 106 and causing the paint to crack. After the opening surface 106 is processed, the top cover enters the hot stamping process. This structure solves the technical problem that the opening surfaces 106 of the outer cover 104 and the outer sleeve 102 are stuck together by the paint during painting, causing the outer cover 104 to be unable to be unscrewed.

[0060] Example 3

[0061] During spray painting, the spraying equipment contains dry paint particles and dust, which can enter the inner plug 105 sealing cavity. Its structure makes it difficult to generate airflow, but because the sealing cavity is in direct contact with the paint, cleaning and dust removal are essential. Further design optimizations were made to address this issue.

[0062] like Figure 10-16 As shown, the ejector fixture 75 includes an outer cylinder 751 and a shaft core 752. The outer cylinder 751 has a through central hole 7512 inside, and several air outlet holes 7511 communicating with the central hole 7512 are evenly distributed around one end of the outer cylinder 751. The shaft core 752 has a through central air passage 7521 inside, and one end of the shaft core 752 has a small-diameter spray section 7523, while the other side has internal and external threads.

[0063] During installation, the external thread of the shaft core 752 is threaded onto the internal thread of the outer cylinder 751, meaning the shaft core 752 is installed inside the outer cylinder 751, forming an airflow cavity 753 between the outer cylinder 751 and the shaft core 752. One end of the shaft core 752 is threadedly connected to an air inlet connector 757; one end of the outer cylinder 751 is connected to a bearing housing 754 via a bearing 755, which is fixed to the mounting base 72. An air outlet connector 756 is provided inside the bearing housing 754, communicating with an air outlet 7511.

[0064] The top cover includes an outer cover 104, an outer sleeve 102, a middle sleeve 103, and an inner plug 105, such as Figure 10As shown, during installation, the ejector cylinder 7 extends, controlling the ejector fixture 75 to extend into the upper cover. Specifically, one end of the outer cylinder 751 extends into the middle sleeve 103 and presses against the inner plug 105. One end of the shaft core 752 is equipped with a smaller diameter jet section 7523, which extends into the inner plug 105. Air intake is indicated by the arrow; the airflow passes through the central air passage 7521 to reach the interior of the inner plug 105, purifying its interior, then flows out through the airflow chamber 753, and finally is discharged externally through the air outlet connector 756.

[0065] In this invention, an ejector fixture 75 is designed with airflow passing through it to clean the inner plug 105. At the same time, the ejector fixture 75 is also designed to press the inner plug 105 in place, which can correct, press, and calibrate the installation position of the inner plug 105. Furthermore, the ejector fixture 75 pressing the inner plug 105 in place can also prevent the inner plug 105 from being dislodged due to the high-pressure cleaning gas passing through it.

[0066] Furthermore, a notch 7522 is provided on the outer side of the shaft core 752, and the outer wall of the shaft core 752 is set tightly against the inner wall of the outer cylinder 751. The notch 7522 and the outer cylinder 751 form a flat airflow cavity 753. This design is because the shaft core 752 has a certain length. In order to ensure the connection strength and stability for high-pressure gas transmission and supporting rotational motion, the shaft core 752 is set tightly against the inner wall of the outer cylinder 751 to ensure connection strength. The notch 7522 is designed so that the notch 7522 and the outer cylinder 751 form a flat airflow cavity 753, which can also realize the flow of air and realize the cleaning operation of the inner plug 105.

[0067] Example 4

[0068] like Figure 5 , Figure 8 As shown, an L-shaped connecting plate 3 is provided on the outer side of the bottom of the guide trough 2. The width of the connecting plate 3 is greater than the width of the guide trough 2, meaning that the disassembly cylinder 4 can have a certain extension stroke to push the upper cover onto the connecting plate 3. A stabilizing cylinder 31 is provided on the connecting plate 3. When the upper cover is pushed off, the stabilizing cylinder 31 presses the upper cover back into place. The stabilizing cylinder 31 is provided because when the disassembly cylinder 4 is extended, in some cases the disassembly fixture 41 will pull the upper cover back. Therefore, the purpose of the stabilizing cylinder 31 is to ensure that the disassembly cylinder 4 can smoothly separate from the upper cover when it retracts, ensuring that the upper cover can reach the guide trough 2.

[0069] Example 5

[0070] The base plate 11 and the side baffle 13 are connected by a reinforcing plate 18 to ensure the connection strength. A material stabilizing cylinder 2 181 is installed on the reinforcing plate 18. The bottom end of the material stabilizing cylinder 2 181 is set directly opposite the material guide groove 2. The material stabilizing cylinder 2 181 is installed here to control the unloading of the upper cover and limit the upper cover, thereby controlling the ejection cylinder 7 to drive the ejection fixture 75 to push out and deliver the upper cover to the finger cylinder 8 station.

[0071] Example 6

[0072] like Figure 4 , 6 As shown in Figures 7, 19, and 20, a top cover discharge trough 16 is provided directly below the clamping mechanism. Specifically, two connecting blocks 91 are provided on the frame 1, and bearing seats 94 are fixed on the connecting blocks 91. Two fixing blocks 96 with threaded holes are provided at the bottom of the top cover discharge trough 16. A rotating shaft 93 is threadedly connected to the threaded holes of the fixing blocks 96, allowing adjustment of the angle of the top cover discharge trough 16 during installation. The rotating shaft 93 is located on both sides within the bearing seats 94. That is, the top cover discharge trough 16 is hinged to the frame 1 via the rotating shaft 93. An L-shaped adjusting plate 92 is provided at one end of the rotating shaft 93. An adjusting cylinder 9 is fixed to the upper end of the connecting block 91, and an adjusting screw 95 is connected to the bottom end of the adjusting cylinder 9. The bottom of the adjusting screw 95 is set close to the adjusting plate 92. A spring 97 is also fixed to the bottom of the top cover discharge trough 16, and the other end of the spring 97 is fixedly connected to the bearing seat 94.

[0073] Initially, under the tension of spring 97, the upper cover discharge chute 16 is tilted toward the qualified frame 19.

[0074] The adjusting plate 92 and the adjusting cylinder 9 are connected for transmission. When the adjusting cylinder 9 extends and retracts, it can control the rotation of the upper cover discharge chute 16 and the docking of the rejection frame 17 (e.g., Figure 20 (as shown), or rotate and align with the qualified frame 19 (as shown). Figure 19 (As shown). This method allows for quick switching of the angle and position of the upper cover discharge chute 16, thereby changing the direction of the material.

[0075] like Figure 20 As shown, under normal circumstances, the top cover discharge slot 16 points towards the rejection frame 17. Once there is a defective product, it will fall directly into the rejection frame. For example, the finger cylinder 8 may not close completely, or it may encounter a deformed cover or some foreign object that prevents the cylinder from reaching the full position. Only when the finger cylinder 8 closes completely, fully squeezing the plastic to deform elastically and causing the opening surface to expand the gap, is it considered qualified. In this case, it points towards the qualified frame 19.

[0076] Working principle:

[0077] Function 1: The steps to complete one decomposition cycle are as follows:

[0078] 1. When the integrated cover enters from the feed chute 12 and passes the photoelectric sensor 23, the disassembly cylinder 4 drives the disassembly fixture 41 to disassemble the upper cover and lower cover 101.

[0079] 2. When the magnetic switch in front of the decomposition cylinder 4 detects that the position has been reached, the material stabilizing cylinder 31 will be activated to fix the top cover.

[0080] 3. When the magnetic switch of the material stabilizing cylinder 31 detects that the position has been reached, the decomposition cylinder 4 retracts and the material is discharged from the lower cover.

[0081] IV. When the magnetic switch detects that the decomposition cylinder 4 has reached the position, the material stabilizing cylinder 31 retracts.

[0082] Function 2: The steps to complete one processing cycle of the open face are as follows:

[0083] 5. When the disassembled top cover is neatly arranged beyond the photoelectric sensor 141, and the magnetic switch of the finger cylinder 8 detects that it is in the open state, the material stabilizing cylinder 181 is deployed to limit the top cover. The ejection cylinder 7 drives the ejection fixture 75 to be deployed, pressing the top cover tightly against the rotating fixture 63 and delivering it to the finger cylinder 8 station.

[0084] 6. When the magnetic switch in front of the ejector cylinder 7 detects that the position has been reached, the finger cylinder 8 performs a clamping and then opening action, and the magnetic switch of the finger cylinder 8 detects whether the clamping is in place; when the clamping and opening action of the finger cylinder 8 is detected by the magnetic switch of the finger cylinder, the stepper motor 61 drives the rotating fixture 63 and the upper cover to rotate 90 degrees once through the synchronous wheel.

[0085] When the 90-degree rotation is complete, the finger cylinder 8 cycles through clamping and opening actions. This is repeated four times, each time at a 90-degree angle. Utilizing the elastic deformation of the plastic, the opening surface creates a gap, causing the paint to crack.

[0086] 7. After the fourth clamping action of the finger cylinder 8 is completed, the ejector cylinder 7 retracts.

[0087] 8. After the ejector cylinder 7 is activated, the magnetic switch detects that the position has been reached, the finger cylinder 8 opens, and the material from the top cover reaches the material discharge slot 16. The material stabilizing cylinder 181 retracts, and the top cover rolls down and is reset.

[0088] Function 3: Complete one cycle of dust removal from the inner plug sealing cavity and inner plug calibration position:

[0089] 9. In the fifth step, the material stabilizing cylinder 2 181 is activated to limit the upper cover, and the shaft core 752 enters the sealing cavity of the inner plug 105. At the same time, the outer cylinder 751 pushes the inner plug 105 into place.

[0090] 10. Before the cylinder is ejected in step 6, the magnetic switch recognizes the position and introduces purified air at a pressure of about 0.4 MPa through the high-speed rotating air inlet 757. Impurities such as dry paint particles flow out through the air outlet 756 along the airflow chamber 753.

[0091] 11. After the clamping action of the finger cylinder is recorded for the third time in step 7, the high-speed rotating air inlet connector 757 stops supplying air pressure, that is, the air supply stops before the ejector cylinder 7 retracts. The purpose is to prevent the ejector cylinder 7 from retracting without properly clamping the inner plug 105, as the high-pressure gas in the sealing cavity of the inner plug 105 would force the inner plug 105 out of position.

[0092] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
