Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag production, in particular to a turnover structure for packaging bag processing. Background Art

[0002] During the production process of packaging bags, when production is completed, multiple packaging bags need to be stacked together, and then put into packaging boxes or collection bags together, uniformly placed, and then transported. In this process, in order to arrange them neatly and facilitate observation of the types and models of the placed packaging bags, it is usually necessary to turn the front of the packaging bag with the pattern information printed on it upwards, and then during the process of conveying the stacked packaging bags by the conveyor belt, the packaging bags need to be flipped by a flipping device.

[0003] When the flipping device on the existing conveyor flips the packaging bag, an L-shaped bracket is set, and a pressure plate and a cylinder are set above the bracket to press the packaging bag on the bracket, and then the bracket is controlled to flip through a rotating mechanism to achieve the flipping of the packaging bag. However, due to the existence of the cylinder structure in the design of this flipping device, the cylinder needs to be connected to the air pipe. Therefore, the flipping device cannot perform a 360° circular motion and can only perform a 180° reciprocating motion. As a result, the flipping device cannot achieve a more continuous and efficient flipping action during this process, and thus cannot continuously flip the packaging bag. After each flip, a pause is required, which affects the production efficiency.

[0004] Therefore, it is necessary to invent a flip structure for packaging bag processing to solve the above problems. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 The flipping structure for packaging bag processing shown in the figure comprises a belt conveyor 1, a driving mechanism 3 is arranged in the middle part of the belt conveyor 1, a motor 31 in the driving mechanism 3 controls a driving rod 32, and the driving rod 32 is connected to a mounting seat 41 of a flipping mechanism 4, so that the circular motion of the flipping mechanism 4 is realized. This design enables the flipping device to perform continuous and efficient flipping actions, thereby improving production efficiency. The flipping mechanism 4 is connected to the top of the belt conveyor 1 through the driving mechanism 3, and the belt conveyor 1 is composed of a frame 11 and a conveyor belt 12.

[0029] The driving mechanism 3 comprises:

[0030] The motor 31 is arranged at one side of the belt conveyor 1, and a driving rod 32 is fixedly installed transversely at the output end of the motor 31;

[0031] The turning mechanism 4 comprises:

[0032] Two mounting seats 41 are arranged above the belt conveyor 1. The two mounting seats 41 are connected to the driving rod 32. A group of clamping strips 42 are fixedly installed on both sides of each mounting seat 41. Each group of clamping strips 42 has two, and the front end of each group of clamping strips 42 is an arc-shaped structure. This structural design of the clamping strips 42 makes it convenient for the flipping mechanism 4 to facilitate the packaging bag to enter between the two clamping strips 42, and can also tightly clamp the packaging bag to ensure that the packaging bag will not slide and fall during the flipping process.

[0033] Furthermore, in the above technical solution, the main part of the belt conveyor 1 is a frame 11, on which are arranged three conveyor belts 12 of different widths, and the three conveyor belts 12 are distributed at equal intervals. This design of the conveyor belts 12 enables the turning mechanism 4 to be arranged between multiple conveyor belts 12, thereby not affecting the circular motion of the turning mechanism 4, and not affecting the conveying of the packaging bags by the conveyor belts 12. Bearing seats 2 are fixedly installed on the outer walls of both sides of the frame 11.

[0034] Furthermore, in the above technical solution, the two ends of the driving rod 32 are rotatably connected to the two bearing seats 2 respectively, the motor 31 is fixedly installed on the outside of a bearing seat 2, and two symmetrically distributed threaded holes 33 are opened on the driving rod 32. The two ends of the driving rod 32 are connected and supported by the two bearing seats 2, so that the driving rod 32 can rotate in a circle on a certain stable horizontal plane, thereby realizing the control of the flipping mechanism 4, and the design of the threaded hole 33 realizes the fixed connection and detachable structure between the mounting seat 41 and the driving rod 32.

[0035] Furthermore, in the above technical solution, through holes 43 are opened on both sides of the mounting seat 41, the mounting seat 41 is connected to the driving rod 32 by insertion through the through holes 43, and the top of the mounting seat 41 is fixedly connected to the threaded hole 33 on the driving rod 32 by bolts.

[0036] Furthermore, in the above technical solution, there is a distance between the side walls of every two conveyor belts 12, and a partition plate 5 is arranged below the side walls of every two conveyor belts 12. The end of each partition plate 5 is fixedly connected to the frame 11, and a plurality of evenly distributed conveying wheels 6 are rotatably installed above each partition plate 5. The upper surface of the conveying wheel 6 is slightly higher than the upper surface of the conveyor belt 12. The bottom of the packaging bag is lifted by the conveying wheel 6 to prevent the packaging bag from being unable to be transported by the conveyor belt 12, thereby achieving the effect of reducing friction.

[0037] Furthermore, in the above technical solution, each group of clamping strips 42 on both sides of the mounting seat 41 is located between every two partition plates 5, and every two conveyor belts 12 are separated by the partition plates 5 to prevent every two conveyor belts 12 from being misaligned and causing friction damage. The bottom of each group of clamping strips 42 is flush with the upper surface of the conveyor belt 12, and a support frame 7 is provided at the front end of the flipping mechanism 4, and the two ends of the support frame 7 are fixedly connected to both sides of the frame 11.

[0038] Furthermore, in the above technical solution, a limiting strip 9 is provided at the bottom of the support frame 7, and cylinders 8 are fixedly installed at both ends of the top of the support frame 7. The output end of the cylinder 8 passes through the support frame 7 and is fixedly connected to the top of the limiting strip 9. The position height of the limiting strip 9 can be adjusted at will through the cylinder 8, so that the limiting strip 9 can be timely adjusted according to different stacking heights of packaging bags.

[0039] The working process of the flip structure for packaging bag processing provided by the utility model is as follows:

[0040] The front end of the belt conveyor 1 with a support frame 7 is the input end, and the rear end is the output end. The stacked packaging bags are fed in from the input end of the belt conveyor 1, and the packaging bags are fed to the position below the support frame 7 through the conveyor belt 12. Since the number of stacked packaging bags is the same, the position height of the limit bar 9 is controlled by the cylinder 8 on the top of the support frame 7 according to different packaging bag types and the number of stacked packaging bags, so that the stacked packaging bags just enter under the limit bar 9, to prevent the stacked packaging bags from being too high due to a large number of stacked packaging bags, which affects the clamping of the packaging bags by the flipping mechanism 4.

[0041] When the stacked packaging bags are transported from the front end of the belt conveyor 1 and pass under the limit strip 9, they enter one end of the flipping mechanism 4, that is, between the two clamping strips 42 of the same group, and then the motor 31 controls the driving rod 32 to rotate, and the mounting seat 41 drives the two groups of clamping strips 42 to rotate 180 degrees, then the clamping strip 42 holding the packaging bag at one end of the mounting seat 41 is flipped to the tail end direction of the belt conveyor 1, and the clamping strip 42 without clamping anything at the other end of the mounting seat 41 is flipped to the front end direction of the belt conveyor 1, that is, the positions of the clamping strips 42 on both sides of the mounting seat 41 are exchanged, and the clamped packaging bags are transported out from the tail end of the belt conveyor 1 through the conveying wheel 6 and the conveyor belt 12, and the front end of the belt conveyor 1 transports a new group of stacked packaging bags to between the two clamping strips 42 at the front end, and is then controlled to flip by the driving mechanism 3, so that the packaging bags are flipped cyclically.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
