Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging machinery, in particular to an automatic capping machine. Background Art
[0002] A can is a sealable container made of metal sheet, glass, plastic, cardboard or a combination of some of the above materials, containing commercial food, which is processed specifically to achieve commercial sterility and can be kept at room temperature for a long time without spoilage. This type of packaged food is called a can.
[0003] During the production process of cans, the most important is the capping work. The principle of the capping machine is to fix the cans and screw the can lids tightly by rotating. However, most of the existing capping devices still have the following problems. Most of the existing can capping devices cannot cap cans of different sizes well. They can often only cap cans of a single specification. When it is necessary to cap cans of different sizes, the fixture needs to be replaced, which is not only time-consuming and laborious, but also affects the efficiency of can processing. Summary of the Utility Model
[0004] Therefore, to solve the above deficiencies, the present utility model provides an automatic capping machine here, which includes a capping assembly and a fifth power device. The capping assembly is driven by the fifth power device to slide vertically. The capping assembly includes a fourth power device and a capper. The capper is driven to rotate by the fourth power device. It also includes an adjustable fixing assembly on which a container can be placed. The adjustable fixing assembly is arranged directly below the capping assembly.
[0005] Among them, the adjustable fixing assembly includes:
[0006] A second power device;
[0007] Two first clamping blocks, which are arranged oppositely. The two first clamping blocks are driven by the second power device to move linearly, so that the two first clamping blocks approach or move away from each other. The first clamping block is used to contact the side of the container in a V shape.
[0008] A placement table, which is arranged below between the two first clamping blocks.
[0009] Furthermore, the placement table is connected to the second power device, and the placement table is driven to move vertically by the second power device;
[0010] The adjustable fixing assembly further includes:
[0011] A fixed seat, and the first clamping block is slidably arranged on the fixed base;
[0012] Connecting rod, the middle part of the connecting rod is pivotally connected to the fixed seat. A first movable groove and a second movable groove are respectively provided at both ends of the connecting rod. The connecting rod is movably connected to the placing table by passing a first connecting pin through the first movable groove and connecting to the placing table; the first clamping block is movably connected to the connecting rod by passing a second connecting pin through the second movable groove and connecting to the first clamping block.
[0013] In the present utility model, by placing the container on the placing table and starting the second power device to drive the first clamping block to move linearly, the container is clamped and fixed. The operation is simple. By controlling the stroke of the first clamping block, the adjustable fixing component can perform adaptive clamping work according to the containers, improving the practical flexibility of the equipment.
[0014] Furthermore, the capping device includes:
[0015] Capping ring, the inner side of the capping ring can accommodate the container lid;
[0016] Second clamping blocks, there are several groups of second clamping blocks. The second clamping blocks are arranged inside the capping ring and around the capping ring. The cross-section of the second clamping block is T-shaped. The step surface of the first part and the second part of the second clamping block is connected to the capping ring through a second elastic member. The second part of the second clamping block protrudes through the side wall of the capping ring to the inner side of the capping ring.
[0017] By pressing the container lid into the capping ring, the container presses the second clamping block to retreat. When retreating, the second elastic member will be stretched, and the second elastic member pulls the second clamping block to act on the container lid in the opposite direction to clamp the container lid, so that it can be adaptively matched according to the specifications of the container lid, realizing the clamping and fixing of container lids of different specifications.
[0018] Furthermore, a first inclined surface is provided at the top end of the second clamping block on the side away from the container lid;
[0019] The capping device further includes a pressing ring, which is wrapped inside the capping ring. A second inclined surface parallel to the first inclined surface is provided on one side of the pressing ring close to the second clamping block, and the first inclined surface contacts the second inclined surface;
[0020] On the upper surface of the pressing ring, there is at least one set of connecting rods protruding upward. The connecting rods pass through the upper surface of the capping ring, extend to the outside, and are connected to the fourth power device. A first elastic member is sleeved on a section of the connecting rod located outside.
[0021] The fifth power device drives the capping assembly to descend vertically. After the capping ring contacts the container, it stops moving, while the fifth power device can continue to move, so that the pressing ring moves downward to squeeze the second clamping block to move outward to hold and fix the container lid, preventing the container lid from loosening during the capping process.
[0022] Furthermore, it also includes a first power device, which drives the adjustable fixing component to slide vertically as a whole.
[0023] The adjustable fixing assembly is driven to rise and fall by the first power device, and can be adaptively adjusted according to the height of the container.
[0024] Furthermore, it also includes a positioning component, which as a whole corresponds to the upper arrangement of the adjustable fixing component, including:
[0025] The third power unit;
[0026] The positioning ring is driven to slide vertically by the third power device.
[0027] The container is initially positioned by the positioning assembly to prevent the container from being excessively offset, which would cause the container to be unable to be screwed into the container cover accordingly.
[0028] Furthermore, it also includes a positioning sensor, which can feedback position signals of the positioning component, the adjustable fixing component and the rotary cover component, so that the controller can control the start and stop of the first power device and the fifth power device.
[0029] The movement travel of the positioning component, the adjustable fixing component and the capping component is limited by the positioning sensor, thereby improving the setting working control accuracy.
[0030] The utility model has the following advantages:
[0031] The utility model places the container on the placing table and starts the second power device to drive the first clamping block to move linearly to clamp and fix the container. The operation is simple, and the stroke of the first clamping block is controlled so that the adjustable fixing component can perform adaptive clamping work according to the containers, thereby improving the practical flexibility of the equipment.
[0032] By pressing the container cover into the screw-on ring, the container will squeeze the second clamping block to retreat. When retreating, the second elastic member will be stretched. The second elastic member will pull the second clamping block to react on the container cover to clamp the container cover. Thus, the container cover can be adaptively matched according to the specifications, thereby achieving the clamping and fixing of container covers of different specifications.
[0033] The fifth power device drives the screw cap assembly to descend vertically, and the screw cap ring stops moving after contacting the container, while the fifth power device can continue to move, so that the extrusion ring moves downward to squeeze the second clamping block to move outward, so as to hold and fix the container cover to prevent the container cover from loosening during the screw capping process.
[0034] The first power device drives the adjustable fixing component to lift, which can be adjusted adaptively according to the height of the container. The position of the container is initially positioned by the positioning component, so as to prevent the container from being overly offset and causing the container to not be screwed into the container lid correspondingly. The movement strokes of the positioning component, the adjustable fixing component, and the capping component are limited by the positioning sensor, thereby improving the working control accuracy of the setting.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation of the present application.
[0057] In this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.
[0058] As described in the background art, most of the existing capping devices still have the following problems. Most of the existing can capping devices cannot perform capping work well on cans of different sizes. They can often only perform capping work on cans of a single specification. When it is necessary to perform capping work on cans of different sizes, it is necessary to replace the fixture, which is not only time-consuming and laborious, but also affects the efficiency of can processing.
[0059] Embodiment 1:
[0060] Therefore, to solve the above technical problems of the prior art, the present embodiment provides an automatic capping machine herein. As Figure 1 shown in 2 Fig. [5], the automatic capping machine includes a capping assembly 700 and a fifth power device 800. The capping assembly is driven by the fifth power device 800 to slide vertically. As Figure 3 shown in
[0061] Fig. [6], the capping assembly includes a fourth power device 710 and a capper 720, and the capper is driven by the fourth power device to rotate;
[0062] As Figure 4 shown in
[0063] a second power device 410;
[0064] a first clamping block 430, there are two groups of the first clamping blocks, and the two groups of the first clamping blocks are arranged oppositely. The first clamping blocks are driven by the second power device to move linearly, so that the two groups of the first clamping blocks approach or move away from each other. The first clamping block 430 is used to contact the side of the container in a V shape;
[0065] a placing table 450, which is arranged below between the two groups of the first clamping blocks.
[0066] Exemplarily, as Figure 5 shown in
[0067] the adjustable fixing assembly 400 further includes:
[0068] a fixing base 420, and the first clamping block 430 is slidably arranged on the fixing base;
[0069] a connecting rod 440, the middle of the connecting rod is pivotally connected to the fixing base. At both ends of the connecting rod, a first movable slot 441 and a second movable slot 442 are respectively provided. The connecting rod is movably connected to the placing table by a first connecting pin passing through the first movable slot and the placing table 450; the first clamping block is movably connected to the connecting rod by a second connecting pin passing through the second movable slot and the first clamping block.
[0070] It should be noted that the figures in the original text are not clearly numbered in a standard way. Here, for the convenience of translation, we assume that the figure numbers are filled in according to the context. You can adjust them according to the actual situation.Before capping, the container can be placed on the upper surface of the placement table 450. Subsequently, the second power device drives the placement table to move vertically downward. Under the push of the connecting rod, the two groups of the first clamping blocks are driven to move linearly simultaneously to hold the container tightly. Then, the container lid is placed on the mouth of the container. The fifth power device drives the capping head to move downward until the capping device completely wraps the container lid. The fourth power device drives the capping device to rotate to screw the container lid tightly onto the mouth of the container to complete capping. The fifth power device drives the capping head to slide up to a safe height. The second power device drives the placement table to slide up. Under the loosening of the connecting rod, the first clamping blocks place the container, and then the container can be taken off.
[0071] In the present utility model, by placing the container on the placement table and starting the second power device to drive the first clamping blocks to move linearly to clamp and fix the container, the operation is simple. By controlling the stroke of the first clamping blocks, the adjustable fixing assembly can perform adaptive clamping work according to different containers, improving the practical flexibility of the equipment.
[0072] In this embodiment, the automatic capping machine may further include a frame 100. The above-mentioned fifth power device can be fixedly installed on the top of the frame. The capping assembly can be slidably connected to the frame through a second sliding seat. The second sliding seat can be connected to the fifth power device. The connection of the second sliding seat to the frame for sliding includes, but is not limited to, a slider-guide rod connection, a slider-rail connection, etc., which can realize the vertical sliding of the second sliding seat relative to the frame.
[0073] In this embodiment, the above-mentioned second power device and fifth power device include, but are not limited to, a cylinder, an electric cylinder, a hydraulic cylinder, a motor-screw structure, a motor-gear rack structure, or other devices or structures that can realize the linear movement of components. The fourth power device includes, but is not limited to, a motor, a rotary cylinder, etc., which can realize the rotation of components.
[0074] Embodiment 2:
[0075] In order to adapt to containers of different specifications, in this embodiment, the capping device is improved on the basis of Embodiment 1, as Figure 6 shown. The capping device in this embodiment includes:
[0076] A capping ring 721, the inner side of which can accommodate the container lid;
[0077] Second clamping blocks 725. As Figure 8 shown, there are several groups of the second clamping blocks 725. The several groups of the second clamping blocks are arranged inside the capping ring 721 and are arranged around the capping ring, as Figure 9As shown, the cross section of the second clamping block is T-shaped, and the step surfaces of the first part 725A and the second part 725B of the second clamping block are connected to the screw cap ring through the second elastic member 726, and the second part 725B of the second clamping block protrudes through the side wall of the screw cap ring to the inner side of the screw cap ring.
[0078] In this embodiment, the container cover is pressed into the screw-on ring so that the container squeezes the second clamping block 725 to retreat. When retreating, the second elastic member is stretched, and the second elastic member pulls the second clamping block 725 to react on the container cover to clamp the container cover. Thus, the container cover can be adaptively matched according to the specifications of the container cover, thereby achieving the clamping and fixing of container covers of different specifications.
[0079] It should be noted that the inner side of the screw-on ring refers to the inner hole of the screw-on ring, which is used to wrap the container cover; the inside of the screw-on ring refers to the inner hollow part of the ring body of the screw-on ring, which is used to install the second clamping block.
[0080] In this embodiment, a flexible layer may be provided on one end of the second part of the second clamping block that clamps the container cover. Similarly, a flexible layer may be provided on one side of the first clamping block that clamps the container.
[0081] In this embodiment, if Figure 7 As shown, a first inclined surface is provided at the top end of the second clamping block away from the container cover;
[0082] The cap screwing device further comprises an extrusion ring 724, which is wrapped inside the cap screwing ring, and a second inclined surface parallel to the first inclined surface is provided on one side of the extrusion ring close to the second clamping block, and the first inclined surface is in contact with the second inclined surface;
[0083] The upper surface of the extrusion ring is provided with at least one group of connecting rods 722 protruding upwards. The connecting rods 722 pass through the upper surface of the rotary cover ring, extend to the outside, and are connected to the fourth power device. A first elastic member 723 is sleeved on a section of the connecting rod arranged on the outside.
[0084] like Figure 10 , 11 As shown, the fifth power device drives the screw cap assembly to descend vertically, and the screw cap ring stops moving after contacting the container, while the fifth power device can continue to work to make the extrusion ring move downward to squeeze the second clamping block to move outward, so as to hold and fix the container cover to prevent the container cover from loosening during the screw capping process.
[0085] In this embodiment, the rotary cover assembly can be connected to the fourth power device via a connecting plate.
[0086] In addition, the automatic capping machine of the present invention may further include a first power device 200, through which the adjustable fixing assembly is driven to slide vertically as a whole.
[0087] The first power device can be fixedly installed at the bottom of the frame body. The adjustable fixing component is connected to the first power device through the first sliding seat 300. The first sliding seat is slidably connected to the frame body, and the connection method refers to the connection method between the second sliding seat and the frame body above.
[0088] The first power device drives the adjustable fixing component to lift and lower, and can be adaptively adjusted according to the height of the container.
[0089] The automatic capping machine of the present utility model may further include a positioning component 600. The positioning component is integrally arranged above the adjustable fixing component and includes:
[0090] A third power device 610, which is fixedly installed on the second sliding seat;
[0091] A positioning ring 620, which is driven by the above third power device to slide vertically.
[0092] The position of the container is initially positioned through the positioning component, so as to avoid excessive deviation of the container and cause the container to not be screwed into the container lid correspondingly.
[0093] Before placing the container, the third power device will drive the positioning ring to descend to a preset height in advance, and the staff can place the container through the positioning ring from top to bottom onto the placement table.
[0094] In addition, the automatic capping machine may further include a positioning sensor 900. The positioning sensor can feedback the position signals of the positioning component, the adjustable fixing component, and the capping component, so that the controller controls the start and stop of the first power device and the fifth power device.
[0095] The above positioning sensor 900 is installed at a preset position on the frame body. When the first power device, the fifth power device, or the third power device is working, after the positioning sensor detects that the adjustable fixing component, the capping component, or the positioning ring moves to the preset position, it immediately feeds back a signal to the controller, so that the controller controls the power device to stop working.
[0096] The movement stroke of the positioning component, the adjustable fixing component, and the capping component is restricted through the positioning sensor, thereby improving the working control accuracy of the setting.
[0097] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
