Description

Technical Field

[0001] The present invention relates to the technical field of the structure of a tank production line, and specifically to a feeding production line adapted to the transportation of tanks with different heights. Background Art

[0002] When packaging cans are being produced, it is necessary to complete the step feeding of the packaging cans through a step jaw mechanism. During the actual transportation of holding the cans, the height of the jaws is set at a fixed position. In actual use, there are differences in the heights of the cans on the production line. When the can is relatively tall, the original jaws with a fixed height position can only hold the relatively lower part of the can. When the jaws hold the can and perform step feeding, the can will tip over or shift due to its too high center of gravity. As a result, the can cannot be reliably and accurately fed to the corresponding workstations, which will lead to inaccurate processing positions of the cans and cause material waste. Therefore, there is an urgent need to develop a feeding production line that can adapt to the transportation of cans with different heights, so as to ensure that cans with different heights can be reliably and accurately held and transported. Summary of the Invention

[0003] In view of the above problems, the present invention provides a feeding production line adapted to the transportation of cans with different heights, which enables the production line to timely add pairs of jaws according to the height of the packaging can, so as to ensure that cans with different heights can be reliably and accurately held and transported.

[0004] A feeding production line adapted to the transportation of cans with different heights, characterized in that it includes:

[0005] A supporting bottom plate, which is provided with an avoidance notch at the position corresponding to the workstation;

[0006] Pairs of driving rods, which are used to drive the step feeding jaws to hold and reciprocate step by step;

[0007] Jaw connecting rods, which are provided in pairs and are arranged parallel to the can transportation direction. The jaw connecting rods include a first jaw connecting rod located in the lower layer and a second jaw connecting rod located in the upper layer;

[0008] Several pairs of jaws, each pair of jaws is respectively fixed on the corresponding jaw connecting rod and is used to hold the can;

[0009] Jaw rod connecting arms;

[0010] And jaw rod height position adjusting arms;

[0011] The middle area of each pair of driving rods is correspondingly provided with the supporting bottom plate. At least two jaw rod connecting arms are respectively arranged along the length direction of each driving rod. The bottom of each jaw rod connecting arm is fixedly installed at the corresponding position of the driving rod. The top of the vertical end of each jaw rod connecting arm is provided with a first connection hole. At least one mounting connection hole is further arranged on the vertical end surface of each jaw rod connecting arm. The first connection hole is fixedly connected with the first jaw connecting rod through a fastener. The lower part of the jaw rod height position adjusting arm is fixedly connected with the mounting connection hole through a fastener. The upper part of the jaw rod height position adjusting arm is provided with a second connection hole. The second connection hole is fixedly connected with the second jaw connecting rod at the corresponding position through a fastener.

[0012] It is further characterized in that:

[0013] The vertical end of the jaw rod height position adjusting arm is provided with a long strip waist hole arranged along the height direction. Two spaced mounting connection holes are arranged in the middle of the vertical end surface of the jaw rod connecting arm in the height direction. The fastener passes through the corresponding position of the long strip waist hole and is fixedly connected to the mounting connection hole. The long strip waist hole enables the height position of the second connection hole of the jaw rod height position adjusting arm to be adjusted according to requirements;

[0014] The first jaw connecting rod and the second jaw connecting rod corresponding to the same up and down position are the same jaw connecting rod. Connecting pieces are respectively fixedly installed at the corresponding positions of each group of jaw connecting rods corresponding to the first connection hole and the second connection hole. Corresponding fixed threaded holes are arranged on the connecting pieces, which ensures the quick and reliable connection of the jaw connecting rods;

[0015] The bottom of the jaw rod connecting arm is a splicing connection structure of two semi-circular rings, which enables the bottom of the jaw rod connecting arm to reliably sheath the driving rod and makes the connection quick and convenient;

[0016] The positions of the jaws on the first jaw connecting rod and the second jaw connecting rod corresponding to the same up and down position are set the same, ensuring the reliable clamping operation of the tank body.

[0017] After adopting the structure of the present invention, when the tank body is relatively high, the driving rod expands, contracts, and reciprocates step by step synchronously, and then drives the first jaw connecting rod and the second jaw connecting rod to expand, contract, and reciprocate step by step synchronously. Since the first jaw connecting rod and the second jaw connecting rod are located at different height positions respectively, the jaws fixed thereon are used to reliably hold two places in the height direction of the tank body, ensuring that the tank body will not tilt or displace during step-by-step transportation. When the tank body is relatively low, the second jaw connecting rod and the corresponding jaw rod height position adjusting arm are quickly removed, and the tank can be held and transported by connecting the corresponding jaws through the first jaw connecting rod; it enables the production line to add paired holding jaws (pre-fixed on the jaw connecting rod) in time according to the height of the packaging tank, so as to ensure that tank bodies of different heights can be reliably and accurately held and transported.

DETAILED DESCRIPTION OF THE INVENTION

[0022] A feeding production line adapted to transport tank bodies of different heights is shown in Figure 1 and Figure 2 , and it includes a supporting bottom plate 10, paired driving rods 20, jaw connecting rods 30, several pairs of jaws 40, jaw rod connecting arms 50, and jaw rod height position adjusting arms 60;

[0023] An avoidance notch 11 is provided at the position of the supporting bottom plate 10 corresponding to the working station, which ensures that the tank body will not accidentally fall;

[0024] The paired driving rods 20 are used to drive the step-by-step feeding jaws to hold and reciprocate step by step;

[0025] The jaw connecting rods 30 are provided in pairs, and the jaw connecting rods 30 are arranged parallel to the tank body transportation direction. The jaw connecting rods 30 include a first jaw connecting rod 31 located at the lower layer and a second jaw connecting rod 32 located at the upper layer;

[0026] Each pair of clamping jaws 40 is fixedly arranged on the corresponding clamping jaw connecting rod 30 respectively and is used for holding the tank body;

[0027] A supporting base plate 10 is correspondingly arranged in the middle area of each pair of driving rods 20. At both ends of each driving rod 20 in the length direction, a clamping jaw rod connecting arm 50 extending upward is fixedly arranged. The bottom of each clamping jaw rod connecting arm 50 is fixedly installed at the corresponding position of the driving rod 20. At the top of the vertical end of each clamping jaw rod connecting arm 50, a first connection hole 51 is arranged. At least one installation connection hole is further arranged on the vertical end surface of each clamping jaw rod connecting arm 50. The first connection hole 51 is fixedly connected to the first clamping jaw connecting rod 31 through a fastener. The lower part of the clamping jaw rod height position adjusting arm 60 is fixedly connected to the installation connection hole through a fastener. A second connection hole 61 is arranged at the upper part of the clamping jaw rod height position adjusting arm 60. The second connection hole 61 is fixedly connected to the corresponding second clamping jaw connecting rod 32 through a fastener.

[0028] During specific implementation, a long strip waist hole 62 arranged along the height direction is arranged at the vertical end of the clamping jaw rod height position adjusting arm 60. Two spaced installation connection holes are arranged in the middle of the vertical end surface of the clamping jaw rod connecting arm 50 in the height direction. The fastener passes through the corresponding position of the long strip waist hole 62 and is fixedly connected to the installation connection hole. The long strip waist hole 62 enables the height position of the second connection hole 61 of the clamping jaw rod height position adjusting arm 60 to be adjusted according to requirements;

[0029] The first clamping jaw connecting rod 31 and the second clamping jaw connecting rod 32 corresponding to the same up and down position are the same clamping jaw connecting rod. Connection pieces 33 are fixedly installed at the corresponding positions of each group of clamping jaw connecting rods corresponding to the first connection hole 51 and the second connection hole 61 respectively. Corresponding fixed threaded holes are arranged on the connection pieces 33, which ensures the quick and reliable connection of the clamping jaw connecting rod 30.

[0030] During specific implementation, the bottom of the clamping jaw rod connecting arm 50 is a two-group semi-circular ring splicing connection structure 52. The two-group semi-circular ring splicing structures 52 are fastened through fasteners to form a central ring sleeve. The driving rod 20 is a round rod, which enables the bottom of the clamping jaw rod connecting arm 50 to be reliably sheathed on the driving rod 20 and makes the connection quick and convenient.

[0031] During specific implementation, the clamping jaws 40 on the first clamping jaw connecting rod 31 and the second clamping jaw connecting rod 32 corresponding to the same up and down position are arranged at the same position, ensuring the reliable clamping operation of the tank body.

[0032] The working principle is as follows: When the tank body is relatively high, assemble the second jaw connecting rod together with the jaws in place, and the driving rod expands, contracts, and reciprocates step by step synchronously, thereby driving the first jaw connecting rod and the second jaw connecting rod to expand, contract, and reciprocate step by step synchronously. Since the first jaw connecting rod and the second jaw connecting rod are located at different height positions respectively, the jaws fixedly installed thereon are used to reliably hold two positions in the height direction of the tank body, ensuring that the tank body will not tilt or displace during step-by-step transportation. When the tank body is relatively low, quickly remove the second jaw connecting rod and the corresponding jaw rod height position adjusting arm, and perform jaw holding and tank feeding through the first jaw connecting rod and its corresponding jaws; it enables the production line to timely add paired jaws (pre-fixed on the jaw connecting rod) according to the height of the packaging tank, thereby ensuring that tank bodies of different heights can be reliably and accurately held and transported.
