Description

Technical Field

[0001] The present invention belongs to the field of assembly accessories for two-piece can measuring equipment, and particularly relates to a can pressing device for two-piece can measuring equipment. Background Art

[0002] A two-piece can refers to a metal container composed of two parts: a can lid and an integrally seamless can body with a bottom. The can body of this kind of metal container is formed into a set shape by a drawing method. The forming method of this cup-shaped container belongs to stamping processing, so two-piece cans are also often called stamped cans. The side wall and bottom of the two-piece can body are of an integral structure without any seams, which makes it have the advantages of high food hygiene quality of the internal contents, safety of the internal contents, light weight, material saving, and simple forming process.

[0003] Since most two-piece cans are used in the food and beverage industry, the production and inspection processes are relatively strict. In the inspection process, in order to ensure the accuracy of the measurement data of the two-piece can body and prevent the can body from tilting when placed, when measuring the data of the can body, the can body needs to be pressed tightly on the inspection station. However, the traditional can pressing device usually uses a cylinder to drive a pressing rod to directly press the can body, and this method is extremely easy to squeeze and deform the can body, resulting in cost losses and inaccurate measurement data. The cooperation process of the can rotating device and the can pressing device on the traditional measuring equipment is relatively troublesome, cannot operate synchronously, the operation process is more cumbersome and the inspection time is prolonged. Summary of the Invention

The 7-shaped pressing rod can slide downward along the linear guide rail by its own gravity until the pressing structure contacts the can body. The pressing structure is directly opposite to the center of the bottom of the can body. The pressing structure includes a pressing rod head shaft vertically installed on the pressing rod, a pressing rod head slidably sleeved outside the pressing rod head shaft, and a spring providing the pressing force. The spring is sleeved outside the pressing rod head and installed between the pressing rod and the pressing rod head. When the pressing structure contacts the can body, the spring drives the pressing rod head to press the can body tightly. With the above structural design of the present can pressing device, the spring is used as the power to press the can body tightly, which can ensure that while pressing the can body tightly, it can avoid the problem that the pressure of the pressing rod is too large due to the direct power provided by the cylinder, resulting in the deformation of the can body, cost losses and inaccurate measurement data. At the same time, the pressing structure is rotatably connected so that the pressing device and the can rotating device can operate synchronously, improving the inspection work efficiency.

[0008] Furthermore, a bearing seat is provided at one end of the 7-shaped pressure rod connected to the clamping structure, and the clamping structure is provided with a bearing that cooperates with the bearing seat. The clamping structure is rotatably installed on the 7-shaped pressure rod through the bearing.

[0009] Furthermore, the 7-shaped pressure rod includes a pressure rod cross beam plate perpendicular to the mounting plate and a pressure rod perpendicular to the pressure rod cross beam plate. One end of the pressure rod cross beam plate is slidably mounted and fixed on the linear guide rail, and the other end is fixedly connected to the pressure rod.

[0010] Furthermore, a cylinder push head for abutting against the pressure rod cross beam is provided at the end of the push rod of the pressure tank cylinder, and the cylinder push head pushes the pressure rod cross beam to move upward along the linear guide rail.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, in combination with the drawings and specific embodiments, the present invention will be further described. It should be noted that on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0019] The can pressing device 42 of the two-piece can measuring equipment of the present invention is as Figures 1-3As shown in the figure, it includes a mounting plate, a linear guide rail 421 mounted on the mounting plate, a 7-shaped pressing rod 422 with one end slidably mounted on the linear guide rail 421, a pressing structure 43 rotatably mounted on the other end of the 7-shaped pressing rod 422, and a tank pressing cylinder 423 for pushing the 7-shaped pressing rod 422 to slide upward along the linear guide rail 421. The 7-shaped pressing rod 422 can slide downward along the linear guide rail 421 by its own gravity until the pressing structure 43 contacts the bottom of the tank body. The pressing structure 43 is directly opposite to the center of the bottom of the tank body. The pressing structure 43 includes a pressing rod head shaft 433 vertically mounted on the pressing rod, a pressing rod head 434 slidably sleeved outside the pressing rod head shaft 433, and a spring for providing a pressing force. The spring is sleeved outside the pressing rod head 434 and installed between the pressing rod and the pressing rod head 434. When the pressing structure 43 contacts the tank body, the spring drives the pressing rod head 434 to press the tank body. With the above structural design of this tank pressing device, using a spring as the power to press the tank body can ensure that while pressing the tank body, it can avoid the problem that the pressure of the pressing rod is too large due to the direct power provided by the cylinder, which causes the tank body to deform, resulting in cost losses and inaccurate measurement data. At the same time, the rotatable connection of the pressing structure 43 enables the pressing device and the tank rotating device to operate synchronously, improving the working efficiency.

[0020] In this embodiment, the 7-shaped pressing rod 422 includes a pressing rod cross beam plate perpendicular to the mounting plate and a pressing rod perpendicular to the pressing rod cross beam plate. One end of the pressing rod cross beam plate is slidably mounted and fixed on the linear guide rail 421, and the other end is fixedly connected to the pressing rod. The end of the push rod of the tank pressing cylinder 423 is provided with a cylinder push head for abutting against the pressing rod cross beam. The cylinder push head pushes the pressing rod cross beam to move upward along the linear guide rail 421. The cylinder push rod of this pressing device is not directly connected to the 7-shaped pressing rod 422, and only provides an upward lifting thrust, not a downward pressing power, to avoid damaging the tank body due to excessive power. A baffle is provided at the upper end of the linear guide rail 421 to prevent the 7-shaped pressing rod 422 from detaching from the linear guide rail 421. This prevents the 7-shaped pressing rod 422 from being pushed upward to the upper limit by the tank pressing cylinder 423 when pushing the 7-shaped pressing rod 422 upward, and then being pushed away from the linear guide rail 421 due to continued upward movement by hand or other reasons.

[0021] The mounting plate of this embodiment is provided with an adjusting block for adjusting the pressing force of the 7-shaped pressing rod 422. The adjusting block is slidably fixed to the mounting plate and is used to block the downward sliding of the 7-shaped pressing rod 422. In this embodiment, the 7-shaped pressing rod 422 moves downward by its own weight until the crossbeam plate of the pressing rod abuts against the adjusting block. At this time, the 7-shaped pressing rod 422 stops moving downward. The weight of the 7-shaped pressing rod 422 causes the spring to contract and the pressing rod head 434 to tightly adhere to the bottom of the tank body. Through the reaction force of the spring, the pressing rod head 434 presses the tank body tightly. The magnitude of the pressing force of this pressing device is mainly changed by the degree of contraction of the spring. By sliding and adjusting the position of the adjusting block, the downward stroke of the 7-shaped pressing rod 422 can be changed, thereby changing the degree of contraction of the spring to achieve the adjustment of the pressing force on the tank body. This enables this pressing device to press tank bodies of different specifications.

[0022] During the processing and production process, the quality of a tank body is not only to detect multiple data at one position, but also to measure the dimensional data of multiple points on the circumferential position of the tank body to be measured. For this reason, two-piece tank measuring equipment usually also includes a tank rotating device for rotating the tank body. After rotating the tank body, the measurement of data such as the height of the tank body and the thickness of the tank wall is re-performed to meet the requirements of the tank body quality inspection process. However, the cooperation process between the tank rotating device and the tank pressing device on traditional measuring equipment is relatively troublesome. When the tank rotating device operates, it usually needs to stop the operation of the tank pressing device and move it away from the tank body. Only then can the tank rotating device operate. It is not until the rotation of the tank rotating device is completed that the tank pressing device presses the tank body again. The operation process is relatively cumbersome and cannot operate synchronously, which prolongs the detection time. In this embodiment, a bearing seat 431 is provided at one end of the 7-shaped pressing rod 422 connected to the pressing structure 43. The pressing structure 43 is provided with a bearing 432 that cooperates with the bearing seat 431. The pressing structure 43 is rotatably mounted on the 7-shaped pressing rod 422 through the bearing 432. Through the above design, the tank pressing device can rotate the tank body while pressing the tank body tightly, without the need to stop pressing the tank body and lift the tank pressing mechanism away from the tank body every time the tank is rotated like traditional measuring equipment, saving the detection time and accelerating the work efficiency.

[0023] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
