Abstract
Description
Technical Field
[0001] The present application relates to the technical field of food packaging equipment, and particularly to a can separating device. Background Art
[0002] Before the sealing of canned foods, generally, vacuum pumping and nitrogen filling are carried out to ensure the storage period and storage quality of the sealed foods. Before the vacuum pumping and nitrogen filling of canned foods, pre-sealing is often carried out. Pre-sealing can facilitate the free overflow of air, water vapor and other gases in the can during vacuum pumping and exhaust, prevent the over-expansion of foods and the spillage of juices during the exhaust process, and is also beneficial to improving the sealing efficiency and tightness.
[0003] Pre-sealing is to roll the lid hook of the lid under the canned body by the action of the rollers of the can seaming machine, so that the two are hooked to each other. The tightness is generally limited to allowing the lid to rotate freely along the canned body without falling off. Specifically, during the pre-sealing process, the canned bodies filled with foods are fed into the indexing turret in batches first. The indexing turret rotates and transfers the canned bodies under the sealing mechanism. At the same time, the can supporting mechanism at the bottom of the canned body rises upward, supporting the canned body so that its top abuts against the can separating pressure head of the sealing mechanism. Through the cooperation of the can supporting mechanism and the can separating pressure head, the canned body rotates itself and acts on the sealing rollers of the sealing mechanism, and the pre-sealing is completed by using the sealing rollers. After pre-sealing, the can supporting mechanism descends and resets, and the indexing turret rotates and transfers the canned bodies away and sends them to the steps of vacuum pumping and nitrogen filling, thus completing the entire sealing process.
[0004] Currently, the can separating pressure head generally includes a housing, a top head and a top head shaft, etc. The housing is installed on the indexing turret. The top head shaft penetrates through the entire housing. The top end of the top head shaft abuts against the cam disc and meshes with the gear disc. The bottom end of the top head shaft is connected to the top head. During pre-sealing, the top end of the top head shaft abuts against the cam disc, and the bottom end abuts against the canned body through the top head, so as to provide top support for the canned body. And, by rotating the gear disc, the top head shaft and the top head are driven to rotate, so that the canned body abutting against the top head can rotate itself.
[0005] However, since the top end of the top head shaft will wear against the cam disc when the top head shaft rotates, the actual length of the top head shaft will become shorter after long-term operation, resulting in insufficient supporting force of the top head shaft and the top head on the canned body, causing the installation of the canned body to be unstable, and even unable to convey the canned bodies in batches in time, resulting in a collision failure.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.
[0035] As described above, when pre-sealing the canned body, the can supporting mechanism lifts the canned body upward to provide bottom support for the canned body. The can separating pressure head is used to abut against the top of the canned body to provide top support for the canned body. By the cooperation of the can supporting mechanism and the can separating pressure head, the canned body can be fixed and the canned body can be rotated, so as to complete the pre-sealing of the canned body in batches. After the existing can separating pressure head is used for a long time, the top end of the top head shaft of the can separating pressure head is prone to wear, resulting in a decrease in the supporting force of the top head shaft and the top head on the canned body in the vertical direction, making it difficult to cooperate with the can supporting mechanism to form a stable support for the canned body, and even unable to convey the canned body in batches in time, causing a collision failure.
[0036] To solve the above problems, the inventor provides a can separating device 10 to replace the existing can separating pressure head.
[0037] Please refer to Figures 1 to 2 , the can separating device 10 provided by the embodiment of the present application includes a housing 100, a first movable assembly 200, a second movable assembly 300, and a can separating top head 400.
[0038] The housing 100 is used to provide an installation basis for other components, and at the same time is used to support and protect other components. Exemplarily, the housing 100 can be in the shape of a hollow cylinder to facilitate the connection and cooperation with the first movable assembly 200. When the can separating device 10 is in use, the housing 100 can be installed on the indexing turret and remain fixed relative to the indexing turret.
[0039] The first movable assembly 200 is rotatably connected to the housing 100, that is, the first movable assembly 200 can rotate relative to the housing 100. The first movable assembly 200 has a movable hole 211, and the movable hole 211 is used to accommodate the second movable assembly 300. Exemplarily, the first movable assembly 200 can be externally connected to a motor and driven by the motor to realize rotation relative to the housing 100.
[0040] The second movable component 300 extends into the movable hole 211 and is connected to the first movable component 200. In this embodiment, a part of the second movable component 300 extends into the movable hole 211 and is connected to the first movable component 200, and the remaining part protrudes outside the movable hole 211 for connecting with the split listening head 400. When the first movable component 200 rotates relative to the housing 100, the second movable component 300 can rotate relative to the housing 100 along with the first movable component 200. Exemplarily, the second movable component 300 can be generally cylindrical in structure, and the movable hole 211 can be a cylindrical hole matching the second movable component 300 to facilitate the second movable component 300 to extend into the movable hole 211.
[0041] The split listening head 400 is connected to the second movable component 300. When the first movable component 200 rotates relative to the housing 100, the first movable component 200 can drive the split listening head 400 to rotate relative to the housing 100 through the second movable component 300.
[0042] Wherein, the second movable component 300 is arranged to be able to move in the movable hole 211 and drive the split listening head 400 to move so that the split listening head 400 abuts against the canned body. Exemplarily, for easy understanding, the canned body in the embodiment of the present application takes a cylindrical structure as an example.
[0043] Through the above structural design, during the pre-sealing process, when the can supporting mechanism lifts the canned body upward so that the canned body contacts the split listening head 400, since the split listening head 400 can move upward in the movable hole 211 along with the second movable component 300, a buffer can be formed to avoid rigid collision between the split listening head 400 and the canned body and cause damage. After the split listening head 400 and the can supporting mechanism respectively form a stable support for the canned body, by rotating the first movable component 200, the second movable component 300 and the split listening head 400 can be driven to rotate, so that the canned body abutting against the split listening head 400 can be driven to rotate, which is beneficial to pre-sealing the canned body. When the can supporting mechanism moves downward and takes away the canned body so that the canned body is separated from the split listening head 400, since the split listening head 400 can move upward in the movable hole 211 along with the second movable component 300, the split listening head 400 can be reset so that the split listening head 400 descends to the initial position, which is convenient for performing the same pre-sealing operation on the next batch of canned bodies.
[0044] Thus, the split listening device 10 provided by the embodiment of the present application can be used for pre-sealing the canned body, and can form a stable support for the canned body, which is beneficial to pre-sealing a large number of canned bodies in batches, with high processing efficiency, and can effectively avoid the risk of crashing.
[0045] As a further preferred embodiment, on the basis of the above solution, in the specific embodiments of the present application, one or more of the following additions or combinations may also be included.
[0046] In some alternative embodiments, the second movable component 300 includes a return spring 310 and a movable shaft 320. The return spring 310 is disposed in the movable hole 211. One end of the movable shaft 320 is connected to the first movable component 200 through the return spring 310, and the other end protrudes outside the movable hole 211 and is rotatably connected to the split listening head 400.
[0047] Specifically, the top end of the return spring 310 is connected to the first movable component 200, the bottom end of the return spring 310 is connected to the top end of the movable shaft 320, and the bottom end of the movable shaft 320 is connected to the split listening head 400. Among them, the return spring 310 is configured to move upward and be compressed when subjected to an upward force from the canned body, the split listening head 400, and the movable shaft 320, and the return spring 310 can expand and reset to its initial state when the force is cancelled, so as to facilitate the same pre-sealing operation for canned bodies of different batches.
[0048] Exemplarily, referring to Figure 1 and Figure 2 , the return spring 310 is located in the movable hole 211. The top end of the movable shaft 320 extends into the movable hole 211 and is connected to the return spring 310. The bottom end of the movable shaft 320 extends outside the movable hole 211 and is connected to the split listening head 400. During the pre-sealing process, when the can supporting mechanism lifts the canned body upward so that the canned body contacts the split listening head 400, the split listening head 400 will squeeze the movable shaft 320 upward, causing the movable shaft 320 to move into the movable hole 211, and at this time the return spring 310 is compressed; at the same time, since the top end of the return spring 310 abuts against the first movable component 200, the return spring 310 will exert a downward elastic force and transmit it to the split listening head 400 through the movable shaft 320, so that the split listening head 400 tightly abuts against the top of the canned body. When the pre-sealing is completed, the can supporting mechanism moves downward and takes away the canned body so that the canned body is separated from the split listening head 400. At this time, the return spring 310 will automatically expand and reset, and drive the movable shaft 320 and the split listening head 400 to descend to the initial position, so as to facilitate the same pre-sealing operation for the next batch of canned bodies.
[0049] Thus, through the cooperation of the return spring 310, the movable shaft 320, and the split listening head 400 in the embodiments of the present application, the automatic reset of the split listening head 400 can be controlled, without manual intervention, which can reduce the safety hazards caused by manual reset and is conducive to improving work efficiency.
[0050] In some alternative embodiments, the return spring 310 and the movable shaft 320 are arranged to extend along the central axis direction of the movable hole 211. At this time, the movable hole 211 can guide the movement directions of the return spring 310 and the movable shaft 320, so that the return spring 310 can expand and contract along the extending direction of the movable hole 211, preventing the movement directions of the return spring 310 and the movable shaft 320 from deviating, which is beneficial to accurately controlling the movement position of the split listening head 400 to stably support the canned body.
[0051] Exemplarily, referring to Figure 1 and Figure 2 , the return spring 310 is a linear spring, the movable shaft 320 is a generally cylindrical structure, and the movable hole 211 is a cylindrical hole. The diameter of the return spring 310 is slightly smaller than the diameter of the movable hole 211. The movable hole 211 limits and guides the return spring 310, enabling the return spring 310 to move as much as possible in the vertical direction. Wherein, the diameter of the return spring 310 is the dimension of the return spring 310 in the horizontal direction in the illustrated perspective.
[0052] In some alternative embodiments, the first movable assembly 200 includes a main shaft 210 and a gear member 220. The main shaft 210 is rotatably connected to the housing 100. One end of the main shaft 210 has a movable hole 211, and the gear member 220 is sleeved outside the other end of the main shaft 210.
[0053] Referring to Figure 1 and Figure 2 , a gear member 220 is provided at the top end of the main shaft 210. The gear member 220 is annularly surrounded outside the main shaft 210, and the gear member 220 is formed with a plurality of teeth. The gear member 220 can cooperate with the driving component to drive the main shaft 210 to rotate relative to the housing 100, and then drive the second movable assembly 300 and the split listening head 400 to move through the main shaft 210, and drive the canned body to rotate itself.
[0054] Exemplarily, the driving component may include a motor and a gear disk (not shown in the figure). The motor can drive the gear disk to rotate. The gear member 220 is used to engage with the gear disk and rotate with the gear disk to achieve the rotation function.
[0055] In some alternative embodiments, a limiting snap ring 321 is protrudingly provided outside the movable shaft 320, and the limiting snap ring 321 is located within the movable hole 211; the first movable assembly 200 further includes a limiting member 230, the limiting member 230 is connected to the main shaft 210, the limiting member 230 has a limiting hole 231, and the limiting hole 231 communicates with the movable hole 211 for the movable shaft 320 to pass through, and the radial dimension of the limiting hole 231 is smaller than the radial dimension of the limiting snap ring 321. By blocking and limiting the movement position of the movable shaft 320 with the limiting snap ring 321, it is possible to prevent the movable shaft 320 from disengaging from the movable hole 211, and at the same time limit the up and down stroke of the split listening head 400 connected to the movable shaft 320.
[0056] Exemplarily, referring to Figure 1 and Figure 2 , the limiting snap ring 321 is annular, protruding from the outer surface of the movable shaft 320 and surrounding the outer periphery of the movable shaft 320. The limiting member 230 is provided at the bottom end of the movable hole 211 and connected to the bottom end of the main shaft 210. For example, the two can be connected by bolts. The limiting member 230 is provided with a through limiting hole 231, the limiting hole 231 communicates with the movable hole 211 and the central axis of the limiting hole 231 is collinear with the central axis of the movable hole 211, so as to facilitate the movable shaft 320 to pass through the movable hole 211 and the limiting hole 231 simultaneously. The radial dimension of the limiting hole 231 is smaller than the radial dimension of the limiting snap ring 321, so that the limiting snap ring 321 is blocked within the movable hole 211, thereby playing a limiting role. Among them, the radial dimension refers to the dimension in the horizontal direction from the perspective of the drawing.
[0057] In some alternative embodiments, the first movable assembly 200 further includes a lubricating member 240, the lubricating member 240 is disposed within the limiting hole 231 and located between the limiting member 230 and the movable shaft 320, for reducing the frictional force when the movable shaft 320 moves relative to the limiting member 230.
[0058] Exemplarily, the lubricating member 240 can be a linear bearing, and the linear bearing is disposed within the limiting hole 231 and sleeved outside the movable shaft 320. The linear bearing can support and position the movable shaft 320, and at the same time can reduce the frictional force when the movable shaft 320 moves along the limiting hole 231, so that the movable shaft 320 can move smoothly and efficiently within the movable hole 211.
[0059] Further, in some alternative embodiments, the linear bearing can be selected to be of a model that only allows the movable shaft 320 to perform linear motion and cannot perform rotational motion. At this time, the movable shaft 320 can move up and down within the movable hole 211 and cannot rotate relative to the linear bearing. Thus, when the main shaft 210 rotates, it can drive the movable shaft 320 to rotate through the linear bearing, thereby driving the split listening head 400 to rotate, and further driving the canned body to rotate.
[0060] In some alternative embodiments, the first movable component 200 further includes a spacer sleeve 250 disposed within the movable hole 211 and located between the lubricating member 240 and the limit snap ring 321. Referring to Figure 1 and Figure 2 , the spacer sleeve 250 can be annular and sleeved outside the movable shaft 320 for separating the limit snap ring 321 from the lubricating member 240, so as to avoid the problem that the limit snap ring 321 directly collides with the lubricating member 240 when the movable shaft 320 moves up and down, which is beneficial to protecting the lubricating member 240 from being damaged.
[0061] It should be noted that during the pre-sealing process, in addition to driving the canned body to rotate by itself through the sound separation device 10, the canned body can also be driven to rotate by itself using the can supporting mechanism. It can be understood that since the sound separation head 400 needs to abut against the top end of the canned body, if the canned body is driven to rotate by itself through the can supporting mechanism, the sound separation head 400 also needs to rotate with the canned body. Correspondingly, the sound separation head 400 can be arranged to be rotatably connected to the movable shaft 320.
[0062] In some alternative embodiments, the sound separation device 10 further includes a first bearing 500 disposed between the movable shaft 320 and the sound separation head 400 and connected to the movable shaft 320 and the sound separation head 400 respectively. Specifically, the first bearing 500 can be cooperated with a snap ring and connected between the movable shaft 320 and the sound separation head 400, so that the sound separation head 400 can rotate relative to the movable shaft 320. Thus, when the can supporting mechanism and the sound separation head 400 respectively support the canned body, when the can supporting mechanism rotates the canned body, the canned body will rotate by itself and drive the sound separation head 400 to rotate, thereby realizing the rotation of the canned body by itself and simultaneously forming an effective support for the canned body using the sound separation head 400.
[0063] Furthermore, referring to Figure 1 and Figure 2 , in some alternative embodiments, the center line of the first bearing 500 is collinear with the center line of the movable shaft 320, so as to facilitate the sound separation head 400 to rotate relatively regularly relative to the movable shaft 320 and facilitate the precise control of the movement position of the sound separation head 400 in the vertical direction.
[0064] In some alternative embodiments, the housing 100 is provided with a fixing hole 110 therethrough; the sound separation device 10 further includes a second bearing 600 disposed within the fixing hole 110; the first movable component 200 passes through the fixing hole 110 and is rotatably connected to the housing 100 through the second bearing 600.
[0065] Referring to Figure 2The housing 100 is provided with a fixing hole 110, for example, the fixing hole 110 can be a cylindrical through hole. The second bearing 600 is arranged in the fixing hole 110 and sleeved outside the main shaft 210, so that the main shaft 210 can rotate relative to the housing 100. Therefore, when the housing 100 is installed, the main shaft 210 can be driven to rotate by itself, thereby driving the second movable component 300 and the can head 400 to rotate, and then the can body can rotate, so as to ensure the smooth realization of the pre-sealing purpose.
[0066] In some optional embodiments, the center line of the fixed hole 110, the center line of the second bearing 600 and the center line of the movable hole 211 are colinear. This is beneficial to improve the stability of the rotation of the main shaft 210 relative to the housing 100, and is also beneficial to drive the second movable component 300, the can head 400 and the can body to rotate stably through the rotation of the main shaft 210, thereby improving the pre-sealing efficiency.
[0067] Furthermore, in some optional embodiments, the dual listening device 10 further includes a connecting member 700 , which is connected to the first bearing 500 and the movable shaft 320 , and is used to fix the first bearing 500 to the movable shaft 320 .
[0068] For example, refer to Figure 1 and Figure 2 The connecting piece 700 can be a bolt and a gasket. The bottom end of the movable shaft 320 is provided with a threaded hole. The first bearing 500 can be fixed to the movable shaft 320 by the bolt and the gasket cooperating with the threaded hole. In this way, the movable shaft 320, the first bearing 500 and the split listening head 400 can be firmly connected, and at the same time, it is easy to assemble and disassemble.
[0069] Optionally, in some embodiments, refer to Figure 1 and Figure 2 The movable shaft 320 is provided with a positioning hole 322, and the positioning hole 322 penetrates the movable shaft 320. When the first bearing 500 needs to be fixed to the movable shaft 320 by bolts, a straight rod can be firstly passed through the positioning hole 322 to limit the movable shaft 320 so that the movable shaft 320 cannot rotate, and then the bolt is screwed into the threaded hole of the movable shaft 320, so that the installation operation is more efficient.
[0070] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
