Description

Technical Field

[0001] The utility model relates to the technical field of iron can processing, in particular to an iron can clamping and positioning device. Background Art

[0002] When printing on the surface of an iron can, a clamping and positioning device is required to clamp and position the iron can.

[0003] A surface printing device for iron can production disclosed in Chinese patent CN218084700U, the surface printing device for iron can production, by placing the can body on a tray, starting the air pump to evacuate, by controlling the suction plate to perform stable vacuum adsorption on the bottom of the can body, when the can body moves to the bottom of the push rod, by controlling the telescopic rod to extend downward, the suction cup can be pushed to adsorb on the top surface of the can body, thereby achieving clamping and positioning. However, while solving the problem, the surface printing device for iron can production has the following defects:

[0004] 1. There is an adsorption plate on the tray, which needs to be connected to the air pump through a bellows. The whole structure is relatively complicated and the cost is high;

[0005] 2. The telescopic rod is extended to allow the suction cup to be adsorbed on the top surface of the can. After printing is completed, when the telescopic rod lifts the suction cup upward, due to the suction force, the suction cup needs to withstand a large pulling force to detach from the can, so the suction cup is easily damaged. Utility Model Content

[0006] The purpose of the utility model is to solve at least one of the technical defects described in the background technology.

[0007] Therefore, one purpose of the utility model is to provide a tin can clamping and positioning device, aiming to solve the problem that the surface printing device for tin can production in the prior art has a relatively complex structure and high cost.

[0008] In order to achieve the above-mentioned purpose, an embodiment of the utility model on one hand provides an iron can clamping and positioning device, including a tray and a cylinder, the cylinder is located above the tray, the top of the tray is provided with a groove, the inside of the groove is fixedly connected with a magnetic block, the output end of the cylinder is fixedly connected with a pressing component, the magnetic block is used to adsorb the iron can to fix the iron can, and the pressing component is used to press down to position the iron can.

[0009] Preferably, any of the above schemes comprises a pressing assembly including a supporting seat and a pressing plate, and a spring is fixedly connected between the supporting seat and the pressing plate, so as to avoid the problem of deformation of the iron can due to excessive force.

[0010] Preferably, any of the above schemes has a first anti-skid pad fixedly connected to the top of the tray and a second anti-skid pad fixedly connected to the bottom of the pressing plate, so as to prevent the iron can from sliding during the printing process after the iron can is clamped and positioned.

[0011] Preferably, any of the above schemes is that the shape of the pressing plate is a truncated cone, and the diameter of the top surface of the pressing plate is larger than the diameter of the bottom surface, and a rubber strip is fixedly connected to the outer surface of the pressing plate, which can be applicable to iron cans with lids and iron cans without lids. For iron cans without lids, the rubber strip can protect the mouth of the iron can and avoid the problem of the iron can being adsorbed on the surface of the pressing plate due to the internal air pressure of the iron can being lower than the external air pressure.

[0012] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0013] 1. After placing the iron can on the top of the tray, the magnetic block can magnetically attract the iron can. This structural design is simple and has low cost, so it is easy to promote.

[0014] 2. The pressing plate and the tray clamp and fix the iron can, and the first anti-skid pad on the top of the tray and the second anti-skid pad at the bottom of the pressing plate can prevent the iron can from sliding when it is against the printing sheet. After printing is completed, the rising pressing plate will directly detach from the iron can, and the structure is not easily damaged, thereby improving practicality.

[0015] 3. A spring is provided between the support seat and the pressure plate, so when the pressure plate presses down to fix the iron can, the problem of the iron can being deformed due to excessive extension of the cylinder can be avoided.

[0016] 4. By setting the pressing plate to a truncated cone shape, it can be applied to iron cans with lids such as cans for printing, and can also be applied to iron cans such as tea cans that usually do not have lids during the printing process. The truncated cone-shaped pressing plate can be applied to iron cans of different calibers, expanding the scope of application.

[0017] 5. By arranging a rubber strip on the outer surface of the truncated cone-shaped pressure plate, the elasticity of the rubber strip can protect the mouth of the iron can to avoid wear and tear. There is a gap between the inner wall of the iron can and the pressure plate, so the outside air can communicate with the inside of the iron can, which can avoid the problem that the air pressure inside the iron can is lower than the outside air pressure, thereby preventing the iron can from being sucked on the surface of the pressure plate when the assembly is lifted and pressed, thereby further improving practicality.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The utility model provides a tin can clamping and positioning device.

[0027] Embodiment 1:

[0028] like Figure 1-2As shown, it includes a tray 1 and a cylinder 2, the cylinder 2 is located above the tray 1, the bottom of the tray 1 is fixedly connected with a slide seat 14 for sliding the tray 1 on the track, the top of the cylinder 2 is fixedly connected with a hanger 21 for sliding the cylinder 2 in the push track, a groove 11 is provided on the top of the tray 1, a magnetic block 12 is fixedly connected inside the groove 11, the magnetic block 12 is embedded in the tray 1, after the iron can is placed on the top of the tray 1, the magnetic block 12 can fix the iron can by magnetic force, so that the iron can will not fall during the movement of the tray 1, the output end of the cylinder 2 is fixedly connected with a pressing component 3, the cylinder 2 is extended, and the pressing component 3 can be lowered and pressed on the top of the iron can, thereby achieving the purpose of clamping and positioning the iron can.

[0029] Specifically, the pressing assembly 3 includes a support seat 31 and a pressing plate 32, and a spring 33 is fixedly connected between the support seat 31 and the pressing plate 32. When the pressing assembly 3 presses down the iron can, after the pressing plate 32 is pressed on the top of the iron can, the spring 33 is compressed, so that the pressing plate 32 is pressed on the top of the iron can by the elastic force of the spring 33. The elastic connection method has a certain buffer distance, which can avoid the problem of the iron can being deformed due to excessive elongation of the cylinder 2. The top of the tray 1 is fixedly connected with a first anti-slip pad 13, and the bottom of the pressing plate 32 is fixedly connected with a second anti-slip pad 34. The iron can is placed on the first anti-slip pad 13 above the tray 1. When the pressing plate 32 presses down to fix the iron can, the second anti-slip pad 34 contacts with the top of the iron can, thereby moving the iron can to make it against the printed sheet, which can avoid the problem of the iron can sliding due to surface force.

[0030] To be more specific, a guide hole 35 is provided at the top of the support seat 31, and a guide rod 36 is fixedly connected to the top of the pressure plate 32. The guide rod 36 is slidably inserted in the guide hole 35. The guide rod 36 limits the moving direction of the pressure plate 32 so that the pressure plate 32 can only move in the up and down directions, thereby making the pressure plate 32 more stable when pressing down to fix the iron can, and the top of the guide rod 36 is fixedly connected to a limiting block 37 to prevent the guide rod 36 from escaping from the guide hole 35.

[0031] Embodiment 2:

[0032] like Figure 3As shown, on the basis of the first embodiment, the pressing plate 32 is in the shape of a truncated cone, and the top diameter of the pressing plate 32 is greater than the bottom diameter. There are usually two types of iron cans. One type of iron can is in the form of an easy-pull can. During printing, the cover on the top of the easy-pull can is lower than the top of the can body. Therefore, the truncated cone-shaped pressing plate 32 can be pressed on the cover of the iron can to fix the iron can. The other type of iron can is in the form of a tea can. This type of iron can is usually not covered during printing. For this type of can, the truncated cone-shaped pressing plate 32 can be inserted into the interior of the iron can, and the outer surface of the pressing plate 32 will support the inner wall of the iron can, thereby fixing the iron can. In this way, when the iron can is against the printing sheet, the pressing plate 32 can provide stability for the iron can. The support can avoid the problem of the iron can sliding under force. The outer surface of the pressing plate 32 is fixedly connected with a rubber strip 38. The rubber strip 38 is elastic, so when the pressing plate 32 is inserted into the inside of the iron can and contacts with the mouth of the iron can, the elasticity of the rubber strip 38 can protect the mouth of the iron can and avoid the problem of wear. The rubber strip 38 abuts against the inner wall of the iron can, so that there is a gap between the inner wall of the iron can and the pressing plate 32, so that the outside air can communicate with the inside of the iron can, avoiding the problem that after the pressing plate 32 is quickly inserted into the inside of the iron can, the air inside the iron can is squeezed out, and then the mouth of the iron can is closed, resulting in the internal air pressure of the iron can being lower than the external air pressure, thereby the iron can be sucked on the surface of the pressing plate 32 when the pressing component 3 is raised.

[0033] The working principle of the utility model is as follows: when in use, the iron can is placed on the top of the tray 1, and the magnetic block 12 magnetically attracts the iron can to fix the iron can on the top of the tray 1 to avoid the problem of the iron can falling during the movement of the tray 1. After the iron can moves to the bottom of the pressing component 3, the cylinder 2 extends, and the pressing plate 32 presses on the top of the iron can or is inserted into the inside of the iron can to fix the iron can, thereby achieving the purpose of clamping and positioning.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. By embedding a magnetic block 12 on the top of the tray 1, after placing the iron can on the top of the tray 1, the magnetic block 12 can magnetically attract the iron can and perform preliminary positioning on the iron can, so that the tray 1 will not slide and fall off during the movement. This structural design is simple and has a low cost, so it is easy to promote.

[0036] 2. By arranging a pressing component 3 under the cylinder 2 and extending the cylinder 2, when the pressing component 3 presses down the top of the iron can, the pressing plate 32 and the tray 1 clamp and fix the iron can, and the first anti-skid pad 13 on the top of the tray 1 and the second anti-skid pad 34 at the bottom of the pressing plate 32 can achieve the purpose of anti-skid, so that the iron can will not slide when it is against the printed sheet. After printing is completed, the cylinder 2 is retracted, the pressing component 3 is raised, and the pressing plate 32 will directly detach from the iron can, and the structure is not easily damaged, thereby improving practicality.

[0037] 3. The pressing assembly 3 includes a support seat 31 and a pressing plate 32. A spring 33 is arranged between the support seat 31 and the pressing plate 32, so that the pressing plate 32 has a certain buffer distance. Therefore, when the pressing plate 32 presses down to fix the iron can, the problem of the iron can being deformed due to excessive extension of the cylinder 2 can be avoided.

[0038] 4. By setting the pressing plate 32 to a truncated cone shape, for iron cans with lids such as cans that are printed, the bottom of the pressing plate 32 can directly press the lid of the can to clamp and position it. For iron cans such as tea cans that usually do not have lids during the printing process, the pressing plate 32 can be directly inserted into the interior of the iron can to clamp and fix it. Therefore, it can be applicable to iron cans of different forms, and the truncated cone-shaped pressing plate 32 can be applicable to iron cans of different calibers, expanding the scope of application.

[0039] 5. By arranging a rubber strip 38 on the outer surface of the truncated cone-shaped pressing plate 32, when the pressing plate 32 is inserted into the iron can and contacts the mouth of the iron can, the elasticity of the rubber strip 38 can protect the mouth of the iron can and avoid the problem of wear. Moreover, since the rubber strip 38 is in direct contact with the mouth of the iron can, there is a gap between the inner wall of the iron can and the pressing plate 32, so the outside air can communicate with the inside of the iron can. This can avoid the problem that after the pressing plate 32 is quickly inserted into the iron can, the air inside the iron can is squeezed out, and then the mouth of the iron can is closed, resulting in the internal air pressure of the iron can being lower than the external air pressure, so that when the pressing component 3 is raised, the iron can is sucked on the surface of the pressing plate 32, thereby further improving the practicality.
