Description

Technical Field

[0001] This utility model relates to the field of capping equipment, and in particular to a capping machine. Background Technology

[0002] In the production processes of industries such as food, pharmaceuticals, and daily chemicals, it is often necessary to install and tighten caps onto the lid to achieve sealed packaging of products. Traditional cap tightening operations rely heavily on manual labor, which is not only inefficient and labor-intensive, but also makes it difficult to ensure the flatness and tightness of the cap installation, easily leading to quality problems such as incomplete sealing.

[0003] With the development of automation technology, some capping machines have appeared on the market. However, most existing capping machines are single-function, typically only capable of tightening the caps. Processes such as cap loading, film application, and pre-installation conveying still require manual assistance or the cooperation of multiple machines. This results in poor coordination between machines, a disjointed overall production process, a large footprint, and difficulty in effectively detecting the presence or absence of caps and films during production, hindering product quality control. Furthermore, the motion precision and stability of the actuators in existing equipment need improvement, further impacting production efficiency and product qualification rates.

[0004] Therefore, there is an urgent need for a capping machine that is highly integrated, highly automated, capable of performing multiple processes in a continuous manner, and can effectively ensure product quality. Utility Model Content

[0039] Reference Figures 1 to 9 This is a capping machine according to some embodiments of the present invention, used to install caps onto cap bodies. It includes a cap body input mechanism 10, a cap body gripping mechanism 11, a guide positioning seat 12, a push tube feeding mechanism 13, a turntable mechanism 14, a cap body detection mechanism 15, a film detection mechanism 16, a film application mechanism 17, a cap conveying vibratory plate 18, a cap installation mechanism 19, a cap tightening mechanism 20, a clamping and unloading mechanism 21, and a finished product output mechanism 22. The turntable mechanism 14 includes a turntable body 141 and a plurality of sleeve fixtures 142 installed on the turntable body 141.

The cover input mechanism 10 is used to input the cover, the cover gripping mechanism 11 is used to grip the cover on the cover input mechanism 10 and place it into the guide groove on the guide positioning seat 12, the push tube feeding mechanism 13 is used to push the cover located on the guide groove onto the sleeve fixture 142, the cover detection mechanism 15 is used to detect whether there is a cover on the sleeve fixture 142, the film application mechanism 17 is used to apply film to the cover, the film detection mechanism 16 is used to detect whether there is film on the cover, the cover conveying vibratory plate 18 is used to convey the cover to the cover mounting mechanism 19, the cover mounting mechanism 19 is used to install the cover onto the cover, the cover tightening mechanism 20 is used to tighten the cover to the cover, the clamping and unloading mechanism 21 is used to grip the finished product that has completed the tightening process onto the finished product output mechanism 22, and the finished product output mechanism 22 is used to convey the finished product out. The cover input mechanism 10, cover gripping mechanism 11, cover detection mechanism 15, film application mechanism 17, film detection mechanism 16, cover installation mechanism 19, cover tightening mechanism 20, and clamping and unloading mechanism 21 are arranged sequentially along the circumferential direction of the turntable mechanism 14.

[0040] Both the cover detection mechanism 15 and the membrane detection mechanism 16 can employ capacitive sensors for detection. The capacitive sensor senses the object being measured through an electric field generated by two electrodes, converting changes in the measured non-electrical quantity into changes in capacitance. When the membrane or cover approaches the sensor surface, the capacitance of the capacitor changes, thus detecting its presence. This sensor has a simple structure, high sensitivity, and can perform non-contact measurements. It can operate under harsh conditions such as high temperature, radiation, and strong vibration, and can reliably detect both conductive and non-conductive membranes or covers. In other embodiments, optical sensors or acoustic sensors can also be used for detection. Both the cover input mechanism 10 and the finished product output mechanism 22 can use a conveyor belt for object transport.

[0041] like Figure 1 and Figure 2 As shown, the functions and connections of each mechanism are as follows: The cover input mechanism 10 continuously inputs the covers to be processed into the equipment's operating area; the cover gripping mechanism 11 grips the covers from the cover input mechanism 10 and transfers them to the guide groove on the guide positioning seat 12; the tube pushing and loading mechanism 13 pushes the positioned covers in the guide groove onto the sleeve fixture 142 of the turntable mechanism 14; the cover detection mechanism 15 detects whether a cover has been successfully loaded onto the sleeve fixture 142; if no cover is detected, the equipment can trigger an alarm or skip the subsequent corresponding process; the film application mechanism 17 applies a film to the covers on the sleeve fixture 142. The cover body is used to achieve sealing or protection functions; the membrane inspection mechanism 16 is used to detect whether the membrane on the cover body is properly attached, so as to prevent the cover body without membrane or with unqualified membrane from entering the next process; the cover conveying vibratory plate 18 is used to arrange the covers in an orderly manner and convey them to the cover installation mechanism 19; the cover installation mechanism 19 is used to accurately install the cover body into the preset position; the cover tightening mechanism 20 is used to tighten the cover body to ensure a firm connection and sealing performance; the clamping and unloading mechanism 21 is used to grab the finished product that has completed the tightening process from the sleeve fixture 142; the finished product output mechanism 22 is used to transport the grabbed finished product to the collection area outside the equipment.

[0042] In terms of layout, the cover input mechanism 10, cover gripping mechanism 11, cover detection mechanism 15, film application mechanism 17, film detection mechanism 16, cover installation mechanism 19, cover tightening mechanism 20, and clamping and unloading mechanism 21 are arranged sequentially along the circumferential direction of the turntable mechanism 14, forming a circular production line around the turntable, ensuring that the cover passes through each process sequentially under the drive of the turntable, and realizing continuous production.

[0043] Understandably, this capping machine integrates a cap input mechanism 10, a cap gripping mechanism 11, a guide positioning seat 12, a push-tube feeding mechanism 13, a turntable mechanism 14, a cap detection mechanism 15, a film detection mechanism 16, a film application mechanism 17, a cap conveying vibratory feeder 18, a cap installation mechanism 19, a cap tightening mechanism 20, a clamping and unloading mechanism 21, and a finished product output mechanism 22 into one unit. These functional mechanisms are arranged sequentially around the turntable mechanism 14, achieving fully automated operation of the entire process from cap feeding, detection, film application, film detection, cap installation, tightening, and finished product output. This eliminates the need for manual intervention or multiple machines, significantly improving production efficiency. Multiple sleeve fixtures 142 on the turntable mechanism 14 can simultaneously carry multiple caps for circulation operations, increasing the machine's operating cycle time. The sleeve fixtures 142 can rotate relative to the turntable body 141, allowing adjustment of the cap's posture according to the requirements of each process, thus improving process adaptability. The inclusion of cover detection mechanism 15 and membrane detection mechanism 16 enables timely identification of defective products lacking covers or membranes, preventing subsequent ineffective processing and effectively ensuring product quality. The overall structure is compact, occupying a small area, and the collaborative operation of each mechanism enhances the equipment's integration and automation level.

[0044] like Figure 3 As shown, the cover gripping mechanism 11 includes a cover gripping mounting base 111, a gripping driver 112, a gripping slide rail 113, a gripping slider 114, a gripping positioning base 115, a first gripping connecting arm 116, a second gripping connecting arm 117, a gripping connecting base 118, and multiple suction devices 119. The gripping driver 112 and the gripping slide rail 113 are both fixedly mounted on the cover gripping mounting base 111. The gripping slider 114 is movably connected to the gripping slide rail 113. The gripping slide rail 113 is arranged in the transverse direction of the cover gripping mounting base 111. The gripping positioning base 115 is fixedly connected to the gripping slider 114. The first gripping connecting arm 116 is connected to the output end of the gripping driver 112. The gripping driver 112 is used to drive the first gripping connecting arm 116 to rotate. The second gripping connecting arm 117 is movably connected to the first gripping connecting arm 116. The second gripping connecting arm 117 is movably connected to the gripping positioning base 115 and can move along the height direction of the gripping positioning base 115. The gripping connecting base 118 is fixedly connected to the second gripping connecting arm 117. Multiple suction devices 119 are mounted on the gripping connecting base 118 and are used to suction the cover on the cover input mechanism 10.

[0045] Specifically, the gripping driver 112 and the gripping slide rail 113 are both fixed on the cover gripping mounting base 111. The gripping slide rail 113 is arranged laterally, and the gripping slider 114 is slidably engaged with the gripping slide rail 113. The gripping positioning seat 115 is fixed on the gripping slider 114 and can move laterally with the gripping slider 114. The first gripping connecting arm 116 is connected to the output end of the gripping driver 112. The gripping driver 112 drives the first gripping connecting arm 116 to rotate. One end of the second gripping connecting arm 117 is movably connected to the first gripping connecting arm 116, and the other end is movably connected to the gripping positioning seat 115 and can slide along the height direction of the gripping positioning seat 115. The gripping connecting seat 118 is fixed to the end of the second gripping connecting arm 117. Multiple suction devices 119 are installed on the gripping connecting seat 118 to grip the cover by negative pressure adsorption. Understandably, in the lid gripping mechanism 11, the gripping driver 112 drives the gripping connecting seat 118 to move via the first gripping connecting arm 116 and the second gripping connecting arm 117. Simultaneously, the gripping positioning seat 115 moves laterally along the gripping slide rail 113 via the gripping slider 114, achieving a combined movement of the suction device 119 in both the lateral and vertical directions. This allows for flexible adjustment of the suction position to adapt to the gripping needs of lids of different sizes and positions. The arrangement of multiple suction devices 119 enables the simultaneous gripping of multiple lids, improving gripping efficiency. The precise coordination of the mechanical structure ensures the stability and accuracy of the gripping action, preventing lids from falling or shifting position during gripping, thus guaranteeing the smooth progress of subsequent processes.

[0046] like Figure 4 As shown, the tube feeding mechanism 13 includes a feeding rotary driver 131, a feeding rotary connecting rod 132, a feeding connecting seat 133, a feeding slide rail 134, and a feeding push rod 135. The two ends of the feeding rotary connecting rod 132 are respectively connected to the output end of the feeding rotary driver 131 and the feeding connecting seat 133. The feeding connecting seat 133 is movably connected to the feeding slide rail 134 via a feeding slider. The feeding push rod 135 is connected to the feeding connecting seat 133 and is used to push the cover located on the guide groove onto the sleeve fixture 142. The tube feeding mechanism 13 uses the feeding rotary driver 131 to drive the feeding rotary connecting rod 132, which in turn drives the feeding connecting seat 133 to slide along the feeding slide rail 134, realizing the reciprocating linear motion of the feeding push rod 135. The structure is simple, the transmission is smooth and reliable, and it can accurately push the cover on the guide groove onto the sleeve fixture 142. The rotary drive method allows for precise control of the stroke of the feeding push rod 135 by adjusting the rotation angle, adapting to the feeding requirements of guide troughs of different lengths and cover bodies of different specifications, thus improving the accuracy and flexibility of feeding.

[0047] like Figure 1 and Figure 2As shown, the film application mechanism 17 includes a loading turntable 171 carrying the film, a hot-pressing film application assembly 172 for applying the film to the cover, and a film pulling assembly 173 for pulling the film. The film application mechanism 17 integrates the loading turntable 171, the hot-pressing film application assembly 172, and the film pulling assembly 173. The loading turntable 171 enables continuous film supply, eliminating the need for frequent film replacements and improving operational continuity. The film pulling assembly 173 automatically pulls the film, working in conjunction with the hot-pressing film application assembly 172 to complete the film application process on the cover, automating the film application process and replacing manual application. This not only reduces labor intensity but also ensures the consistency and firmness of the film application position, improving the product's appearance quality and sealing performance.

[0048] like Figure 5 As shown, the hot-pressing film-applying assembly 172 includes a film-applying mounting base 1721, a film-applying connecting base 1722, multiple film-applying guide wheels 1723, a film-applying push driver 1724, and a film-applying pushing action base 1725.

The multiple film-applying guide wheels 1723 are mounted on the film-applying connecting base 1722 and used to guide the film body. The film-applying push driver 1724 is mounted on the film-applying connecting base 1722, and its output end is connected to the film-applying pushing action base 1725. The film-applying pushing action base 1725 is used to apply the film body to the cover. Specifically, the film-applying connecting base 1722 is fixed to the film-applying mounting base 1721, and the multiple film-applying guide wheels 1723 are spaced apart on the film-applying connecting base 1722 to guide and tension the film body, ensuring smooth film delivery. The film application push driver 1724 is mounted on the film application connector 1722, and its output end is connected to the film application push seat 1725. The film application push seat 1725 can move under the drive of the driver to heat-press the film onto the cover. Understandably, the multiple film application guide wheels 1723 in the hot-press film application assembly 172 can precisely guide the film, ensuring that the film does not shift during transport and guaranteeing the accuracy of the film application position. The film application push driver 1724 drives the film application push seat 1725 to apply the film onto the cover. The driving force is stable, and the pushing force and stroke can be adjusted according to the cover specifications and film characteristics to adapt to different film application needs. The overall structure is compact, the film application action is responsive, and the film application efficiency and quality are improved.

[0049] like Figure 6As shown, the membrane pulling assembly 173 includes a membrane pulling mounting base 1731, a membrane pulling driver 1732, a membrane pulling drive wheel 1733, and a membrane pulling guide wheel 1734. The membrane pulling driver 1732 is mounted on the membrane pulling mounting base 1731, and its output end is connected to the membrane pulling drive wheel 1733. Both the membrane pulling drive wheel 1733 and the membrane pulling guide wheel 1734 are movably mounted on the membrane pulling mounting base 1731. The membrane pulling assembly 173 drives the membrane pulling drive wheel 1733 to rotate via the membrane pulling driver 1732, which, in conjunction with the membrane pulling guide wheel 1734, enables automatic pulling and conveying of the membrane. The pulling speed and force can be precisely controlled by the membrane pulling driver 1732 to ensure the smoothness and continuity of membrane conveying and prevent stretching deformation or breakage of the membrane. The structure is simple in design and reliable in operation, providing a stable supply of film for the smooth operation of the film application process.

[0050] Furthermore, such as Figure 7As shown, the lid mounting mechanism 19 includes a lid mounting positioning seat 191, a lid mounting slide rail 192, a lid mounting slider 193, a lid mounting connecting seat 194, a lid mounting clamping driver 195, a lid mounting clamping action seat 196, a lid pushing in driver 197, a lid mounting guide seat 198, and a lid pushing in connecting seat 199. A cover mounting slide rail 192 is mounted on a cover mounting positioning seat 191. A cover mounting slider 193 is movably connected to the cover mounting slide rail 192. A cover mounting connecting seat 194 is fixedly connected to the cover mounting slider 193. A cover mounting clamping driver 195 is mounted on the cover mounting connecting seat 194, and the output end of the cover mounting clamping driver 195 is connected to the cover mounting clamping action seat 196. A cover mounting guide seat 198 is correspondingly connected to the output end of the cover conveying vibratory plate 18, and the outlet of the cover mounting guide seat 198 is correspondingly set with the cover mounting clamping action seat 196. The cover mounting clamping action seat 196 is provided with a cover limiting groove 1961 for cover positioning. The output end of the cover pushing driver 197 is connected to the cover pushing connecting seat 199. The cover pushing connecting seat 199 is fixedly connected to the cover mounting connecting seat 194, and the side wall of the cover pushing connecting seat 199 is correspondingly set with the cover limiting groove 1961. When the lid is in the lid limiting groove 1961, the lid-mounting actuator 197 pushes the lid-mounting connecting seat 199 to move, thereby mounting the lid onto the lid body. Specifically, the lid mounting slide rail 192 is mounted on the lid mounting positioning seat 191, the lid mounting slider 193 slides with the lid mounting slide rail 192, and the lid mounting connecting seat 194 is fixed on the lid mounting slider 193. The lid mounting tightening actuator 195 is mounted on the lid mounting connecting seat 194, and its output end is connected to the lid mounting tightening action seat 196. The lid mounting guide seat 198 is connected to the output end of the lid conveying vibratory plate 18, guiding the lid into the lid limiting groove 1961 of the lid mounting tightening action seat 196. The output end of the lid-mounting actuator 197 is connected to the lid-mounting connecting seat 199. After the lid is positioned in the limiting groove, the lid-mounting actuator 197 pushes the lid-mounting connecting seat 199 to move, pushing the lid into the mounting position of the lid body. Understandably, in the lid installation mechanism 19, the lid installation guide seat 198 is correspondingly connected to the lid conveying vibratory plate 18, which can accurately convey the lid into the lid limiting groove 1961 of the lid installation tightening seat 196. The lid limiting groove 1961 can position the lid and prevent the lid from shifting during installation. The lid installation tightening driver 195 can drive the lid installation tightening seat 196 to tighten the lid, and the lid push-in driver 197 pushes the lid push-in connecting seat 199 to move and accurately install the lid onto the lid body.

[0051] like Figure 8 As shown, the cover tightening mechanism 20 includes a tightening mounting base 201, a tightening slide rail 202, a tightening push driver 203, a tightening connecting base 204, a tightening action driver 205, a tightening action execution block 206, a tightening positioning base 207, a tightening pressure driver 208, and a tightening pressure action block 209. Tightening slide rail 202 is mounted on tightening mounting base 201. Tightening connecting base 204 is connected to tightening slide rail 202 via tightening slider. Tightening push driver 203 is mounted on tightening mounting base 201 and its output end is connected to tightening connecting base 204. Tightening action driver 205 is mounted on tightening connecting base 204 and its output end is connected to tightening action execution block 206. Tightening action driver 205 is used to drive tightening action execution block 206 to rotate in order to tighten the cover. Tightening positioning base 207 is mounted on tightening mounting base 201. Tightening pressing driver 208 is mounted on tightening positioning base 207 and its output end is connected to tightening pressing action block 209. Tightening pressing driver 208 is used to drive tightening pressing action block 209 to press down on the cover. Specifically, the tightening slide rail 202 is mounted on the tightening mounting base 201, and the tightening connecting base 204 is connected to the tightening slide rail 202 via a tightening slider. The tightening push driver 203 drives the tightening connecting base 204 to move along the tightening slide rail 202, adjusting the position of the tightening action block 206.

A tightening pressing driver 208 is mounted on the tightening positioning base 207, and its output end is connected to the tightening pressing action block 209. During the tightening process, the tightening pressing action block 209 presses down on the cover to prevent the cover from rotating with it. In essence, during the tightening process, the cover tightening mechanism 20 uses the tightening pressing driver 208 to drive the tightening pressing action block 209 to press down on the cover, fixing it in place and preventing it from rotating with the cover during tightening, thus ensuring the stability of the tightening operation. The tightening actuator 203 drives the tightening connector 204 to move along the tightening slide rail 202, adjusting the position of the tightening action block 206 to accommodate the tightening requirements of different cap sizes. The tightening action actuator 205 drives the tightening action block 206 to tighten the cap. The tightening torque can be precisely controlled to ensure consistent tightening of the caps, avoiding problems such as insufficient sealing due to excessive looseness or damage to the cap due to excessive tightness, thus significantly improving the sealing quality and consistency of the product.
