Description

Technical Field

[0001] This utility model belongs to the technical field of bottle cap tightening equipment, specifically relating to a multi-purpose capping and screwing machine with compensation. Background Technology

[0002] A bottle cap tightening machine is a mechanical device used for automatically tightening bottle caps, widely used in the beverage, cosmetics, and pharmaceutical industries. It securely fixes the cap to the bottle opening through rotation and compression, ensuring product sealing and preventing leakage. This equipment is typically adjustable to accommodate different bottle opening and cap specifications and is characterized by high efficiency and stability, significantly improving the automation level and production efficiency of the production line.

[0003] When tightening bottle caps, they are usually flattened first, which can easily damage them. Also, some bottle cap tightening devices, if tightened directly in the forward direction, can cause the cap to jam because it is tilted. Furthermore, some bottle cap tightening devices rely on manually adjusting the distance between the capping rollers, which can lead to rigid contact between the rollers and the cap, causing jamming and preventing tightening. Additionally, some devices make it difficult to quickly visually assess the condition of the bottle and cap, hindering timely problem detection. Utility Model Content

[0004] To address the aforementioned shortcomings, this invention provides a multi-purpose capping and pressing machine with compensation. Through the cooperation of multiple capping mechanisms and an intermediate capping mechanism, this invention enables efficient tightening of bottle caps and bottles without jamming or damaging the caps. By using a cylinder module in conjunction with a bidirectional lead screw, a first slide rod, and a second slide rod, this invention allows for manual adjustment of the distance between the capping wheels of the two motors to accommodate caps of different sizes. Simultaneously, pneumatic compensation enables adaptive clamping, with the capping wheels adjusting according to the actual position of the bottle cap to prevent over-tightening or under-tightening. This invention reduces the capping amplitude, enabling rapid flattening without causing cap jamming or damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-purpose capping and pressing machine with compensation includes a machine body. A bottle transfer track is fixedly installed on the top of the machine body, and multiple bottles are placed inside the bottle transfer track. A bottle cap slide is fixedly installed above the front part of the bottle transfer track. Bottle cap limiting rods are rotatably connected to both sides of the end of the bottle cap slide via torsion springs, and multiple bottle caps are placed inside the bottle cap slide. Two belt drive mechanisms are also symmetrically fixedly installed on the top of the machine body for clamping and moving the bottles. Multiple sets of capping mechanisms are also fixedly installed on the top of the machine body via a bracket. An intermediate capping mechanism is also fixedly installed on the bracket located in the middle of the multiple sets of capping mechanisms.

[0006] Furthermore, the capping mechanism includes two first counter-rotating motors, two second forward-rotating motors, two third forward-rotating motors, and two fourth forward-rotating motors arranged in sequence, with a capping wheel fixedly connected to the output end of each motor; four bidirectional lead screws are rotatably connected to the bracket, with both ends of each bidirectional lead screw threadedly connected to the base of a cylinder module; a first slide rod is fixed to the bracket above the bidirectional lead screw, and the first slide rod is slidably connected to the base of the corresponding cylinder module; a second slide rod is also fixed to the bracket on one side of the first slide rod, and both the first and second slide rods are slidably connected to the base of the corresponding motor; the output end of the cylinder module is fixedly connected to the base of the corresponding motor.

[0007] Furthermore, an adjustment handle is fixedly connected to one end of the bidirectional lead screw.

[0008] Furthermore, the intermediate pressing mechanism is located between the two second positive rotary motors and the two third positive rotary motors; a middle plate is fixedly connected to the middle of the first slide rod and the second slide rod, and the intermediate pressing mechanism is installed in the middle of the middle plate; the intermediate pressing mechanism includes two guide rods slidably connected to the middle plate, an adjusting plate is fixedly connected to the top of the two guide rods, a threaded rod is rotatably connected to the middle of the adjusting plate, one end of the threaded rod is fixedly provided with an adjusting handle, and the other end is fixedly connected to the back of the pressing groove; multiple rollers are rotatably connected inside the pressing groove; the bottom ends of the two guide rods are fixedly connected to the back of the pressing groove.

[0009] Furthermore, a first cap-supporting mechanism is installed at one end of the middle plate near the bottle cap slide. The first cap-supporting mechanism includes a folding plate and a slide fixedly connected to the folding plate. The slide is slidably connected to the middle plate, and the slide and the middle plate are connected by a spring. The middle plate is also equipped with multiple second cover-supporting mechanisms, the structure of which is the same as that of the first cover-supporting mechanism.

[0010] Furthermore, a limiting plate is fixedly installed above the bottle cap slide.

[0011] Furthermore, the belt drive mechanism includes two roller frames fixed to the top of the machine body, and roller belts are installed on the roller frames; a drive motor is fixedly installed on the roller frames, and the output end of the drive motor is fixedly connected to the rollers of the roller frames; the bottle body is located between the two roller frames.

[0012] Furthermore, an infrared rangefinder is fixedly installed above the rear of the bottle transfer track.

[0013] Furthermore, a protective cover is inserted into the top of the bracket.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model, through the cooperation of multiple capping mechanisms and an intermediate capping mechanism, enables the bottle cap and bottle body to be tightened efficiently without jamming or damaging the bottle cap; specifically, when the bottle body moves on the bottle transfer track, the bottle mouth of the bottle body will be pulled out from the two limit rods through the bottom of the bottle cap slide; at this time, the bottle cap is tilted, and then the capping wheel of the first counter-rotating motor is rotated in reverse to straighten the tilted bottle cap and align it with the bottle mouth; then, the capping wheel of the second forward rotating motor is rotated in reverse to straighten the tilted bottle cap and align it with the bottle mouth; then, the capping wheel of the second forward rotating motor is rotated in reverse to straighten the bottle cap and align it with the bottle mouth. The first rotation of the rotary motor initiates the initial screwing of the bottle cap. At this stage, the cap is not fully tightened, allowing for some trial and error. If the cap is still not aligned after the initial rotation, the central pressing mechanism flattens it. This small-amplitude flattening operation is sufficient to align the cap without jamming it, and the small flattening amplitude will not damage the cap. Finally, the third and fourth rotary motors complete the tightening process, greatly improving the success rate of capping.

[0015] (2) This utility model, through the cooperation of the cylinder module with the bidirectional lead screw, the first slide rod, and the second slide rod, can manually adjust the distance between the capping wheels of the two motors to adapt to bottle caps of different sizes. At the same time, it can also achieve adaptive clamping through pneumatic compensation. The capping wheels will adaptively adjust according to the actual position of the bottle cap, so that there will be no situation of clamping too tightly or too loosely. Specifically, by adjusting the rotation of the handle, due to the guiding effect of the first slide rod, the two cylinder modules on the bidirectional lead screw move towards or away from each other synchronously; and the output end of the cylinder module and The base of the corresponding motor is fixedly connected, so the motor and the corresponding capping wheel can move synchronously, allowing manual adjustment of the distance between the two motor capping wheels to accommodate bottle caps of different sizes. At the same time, since both the first and second slide rods are slidably connected to the base of the corresponding motor, a compensating fixing force is applied to the motor under the action of the cylinder module's output, ensuring that the capping wheel can always press the bottle cap. Adaptive clamping is achieved through pneumatic compensation, and the capping wheel will adaptively adjust according to the actual position of the bottle cap, thus preventing the clamping from being too tight or too loose.

[0016] (3) This utility model, through the positional design of the intermediate capping mechanism, compared to the conventional direct flattening process, places the intermediate capping mechanism between two second forward rotating motors and two third forward rotating motors. This allows the cap to be initially adjusted before flattening, reducing the capping amplitude and enabling rapid flattening. Furthermore, since the cap has already been adjusted by both forward and reverse rotation, there is no problem of the cap getting stuck or damaged. The relative height of the rollers can be changed by adjusting the threaded rod, thus allowing for rapid adjustment based on the height of the bottle. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Example like Figures 1-5 As shown, a multi-purpose capping and pressing machine with compensation includes a body 100. A bottle transfer track 200 is fixedly installed on the top of the body 100, and multiple bottles are placed inside the bottle transfer track 200. A bottle cap slide 400 is fixedly installed above the front part of the bottle transfer track. Bottle cap limiting rods 420 are rotatably connected to both sides of the end of the bottle cap slide 400 via torsion springs. Multiple bottle caps are placed inside the bottle cap slide 400. Two belt drive mechanisms 500 are also symmetrically fixedly installed on the top of the body 100 for clamping and moving the bottles. Multiple capping mechanisms 600 are also fixedly installed on the top of the body 100 via a bracket 110. An intermediate capping mechanism 700 is also fixedly installed on the bracket 110 located in the middle of the multiple capping mechanisms 600.

[0021] This utility model, through the cooperation of multiple sets of capping mechanisms 600 and intermediate capping mechanism 700, enables the bottle cap and bottle body to be tightened efficiently without jamming or damaging the bottle cap; a detailed description follows.

[0022] Furthermore, the capping mechanism 600 includes two first counter-rotating motors 610, two second forward rotating motors 620, two third forward rotating motors 630, and two fourth forward rotating motors 640 arranged in sequence, with a capping wheel fixedly connected to the output end of each motor; four bidirectional lead screws 810 are rotatably connected to the bracket 110, with both ends of each bidirectional lead screw 810 threadedly connected to the base of a cylinder module 850; a first slide rod 820 fixed to the bracket 110 is provided above the bidirectional lead screw 810, and the first slide rod 820 is slidably connected to the base of the corresponding cylinder module 850; a second slide rod 830 fixed to the bracket 110 is also provided on one side of the first slide rod 820, and both the first slide rod 820 and the second slide rod 830 are slidably connected to the base of the corresponding motor; the output end of the cylinder module 850 is fixedly connected to the base of the corresponding motor.

[0023] When the bottle moves on the bottle transfer track 200, passing under the cap slide 400, the bottle mouth will be pulled out by the two limit rods 420 with a cap. At this time, the cap is tilted. Then, the capping wheel of the first counter-rotating motor 610 rotates in the reverse direction to straighten the tilted cap and align it with the bottle mouth. Then, the capping wheel of the second forward rotating motor 640 rotates forward to achieve initial capping. At this time, the cap is not tightened, so there is a certain degree of trial and error. If the cap is still not straight after the initial forward rotation, the middle pressing mechanism 700 in the middle flattens the cap. This only requires a small flattening operation to straighten the cap without jamming, and the small flattening will not damage the cap. Finally, the third forward rotating motor 630 and the fourth forward rotating motor 640 finally achieve the tightening operation, thus greatly improving the success rate of capping.

[0024] It is worth noting that the motors and other power equipment in this application are all powered by external power sources, which is a standard setup and will not be described in detail here.

[0025] Furthermore, an adjustment handle is fixedly connected to one end of the bidirectional lead screw 810.

[0026] This invention, through the cooperation of cylinder module 850, bidirectional lead screw 810, first slide rod 820, and second slide rod 830, allows for manual adjustment of the distance between the capping wheels of the two motors to accommodate bottle caps of different sizes. Simultaneously, it achieves adaptive clamping through pneumatic compensation, with the capping wheels adjusting adaptively according to the actual position of the bottle cap to prevent over-tightening or over-loosening. Specifically, by rotating the handle, the first slide rod 820 guides the two cylinder modules 850 on the bidirectional lead screw 810 to move synchronously closer or further apart; while cylinder module 850… The output end of 0 is fixedly connected to the base of the corresponding motor, so the motor and the corresponding capping wheel can move synchronously, thereby manually adjusting the distance between the capping wheels of the two motors to adapt to bottle caps of different sizes; at the same time, since the first slide bar 820 and the second slide bar 830 are both slidably connected to the base of the corresponding motor, under the action of the output end of the cylinder module 850, a compensating fixing force will be applied to the motor, so that the capping wheel can press the bottle cap at all times. Adaptive clamping is achieved through pneumatic compensation. The capping wheel will adaptively adjust according to the actual position of the bottle cap, so that the clamping will not be too tight or too loose.

[0027] Furthermore, the intermediate capping mechanism 700 is located between the two second positive rotary motors 620 and the two third positive rotary motors 630; the middle plate 120 is fixedly connected to the middle of the first slide rod 820 and the second slide rod 830, and the intermediate capping mechanism 700 is installed in the middle of the middle plate 120; the intermediate capping mechanism 700 includes two guide rods slidably connected to the middle plate 120, the top ends of the two guide rods are fixedly connected to an adjusting plate 710, the middle of the adjusting plate 710 is rotatably connected to a threaded rod 720, one end of the threaded rod 720 is fixedly provided with an adjusting handle 730, and the other end is fixedly connected to the back of the pressure groove 740; multiple rollers 750 are rotatably connected in the pressure groove 740; the bottom ends of the two guide rods are fixedly connected to the back of the pressure groove 740.

[0028] This invention, through the positioning design of the intermediate capping mechanism 700, differs from the conventional method of directly flattening the bottle cap. By placing the intermediate capping mechanism 700 between two second forward-rotating motors 620 and two third forward-rotating motors 630, the bottle cap is initially adjusted before flattening. This reduces the capping amplitude, enables rapid flattening, and, because it has already undergone counter-rotation and forward-rotation adjustments, prevents the bottle cap from jamming or becoming damaged. The relative height of the rollers 750 can be changed by adjusting the threaded rod 720, allowing for quick and adaptable adjustments based on the bottle's height.

[0029] Furthermore, a first cap-supporting mechanism 660 is installed at one end of the middle plate 120 near the cap slide 400. The first cap-supporting mechanism 660 includes a folding plate and a slide fixedly connected to the folding plate. The slide is slidably connected to the middle plate 120, and the slide and the middle plate 120 are connected by a spring. The middle plate 120 is also equipped with a plurality of second cover mechanisms 650, the structure of which is the same as that of the first cover mechanism 660.

[0030] The elastic structure design of the first cap-supporting mechanism 660 and the second cap-supporting mechanism 650 ensures that the bottle cap is always under the pressure of the folding plate, thereby preventing problems such as the bottle cap falling off.

[0031] Furthermore, a limiting plate 410 is fixedly installed above the bottle cap slide 400. The limiting plate 410 prevents the bottle cap from falling off the bottle cap slide 400.

[0032] Furthermore, the belt drive mechanism 500 includes two roller frames 510 fixed to the top of the machine body 100, and roller belts 520 are installed on the roller frames 510; a drive motor 530 is fixedly installed on the roller frames 510, and the output end of the drive motor 530 is fixedly connected to the rollers of the roller frames 510; the bottle body is located between the two roller frames 510.

[0033] The rollers on the roller frame 510 are driven to rotate by the drive motor 530, thereby causing the synchronously driven roller belt to move the bottle body.

[0034] Furthermore, an infrared rangefinder 300 is fixedly installed above the rear of the bottle transfer track 200. The infrared rangefinder 300 can measure the height of the bottle cap after it is tightened, thereby quickly detecting whether any bottle caps are not tightened properly. If there is a problem with the caps not being tightened properly, the height of the bottle caps will be higher, which can be detected by the infrared rangefinder.

[0035] Furthermore, a protective cover 130 is inserted into the top of the bracket 110.

[0036] This utility model, through the design of the protective cover 130, can not only protect the equipment parts, but also allow for quick observation of the screwing of the bottle cap and bottle body by looking down when the protective cover 130 is used.

[0037] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
