Description

Technical Field

[0001] The invention relates to a conveying mechanism in packaging bag making equipment, in particular to a conveying device for paper bag flat rope externally attached handles. Background Art

[0002] Paper bags are used more and more widely. For paper bag handles, since the flat rope handles do not have handle pieces, the flat rope is directly glued to the outside of the paper bag with glue, thereby reducing paper costs and production costs. This also makes the application of flat rope handles attached to the outside of paper bags more popular, and the market quantity has skyrocketed. In the prior art, in order to improve manufacturing efficiency, the flat rope handles need to be grasped one by one by finger claws during the production process and then transported to the handle production site. However, since the width of the flat rope is very narrow, it is easy to miss the grasping problem when using finger claws. In addition, the flat rope is transported to the handle production site by a belt, and the finger claws should avoid touching the belt, which makes the finger claw bite space small. Therefore, the finger claw bite flat rope is unstable, and it is easy for the flat rope to be not delivered in place and the flat rope to be blocked, affecting the stable operation of the machine. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a paper bag flat rope external handle conveying device which can effectively avoid the problem of missed grasping and has reliable grasping, thereby ensuring that the flat rope handle can be accurately and stably conveyed.

[0004] In order to solve the above technical problems, the paper bag flat rope external handle conveying device of the present invention includes a main shaft installed by wall panel support and a pin mechanism fixedly installed on the main shaft. The main shaft is provided with a pin swinging device for driving the pin mechanism to swing. The pin mechanism is installed in coordination with the pin swinging device and can be driven by the pin swinging device to swing to the position of the flat rope handle. An angle adjustment mechanism for adjusting the swinging angle of the pin mechanism is also provided on the wall panel. The angle adjustment mechanism is connected to the main shaft through a connecting rod mechanism and can drive the main shaft to rotate through the connecting rod mechanism under the drive of the angle adjustment mechanism so that the pin on the pin mechanism faces the flat rope handle.

[0005] The pin mechanism includes a pair of fixing seats with mounting sleeves fixedly mounted on the main shaft, a connecting shaft mounted through two mounting sleeves, two pin mounting assemblies with the pins mounted on the connecting shaft, and a pendulum installed on one side end of the connecting shaft for cooperating with the pin swinging device.

[0006] The pin installation assembly comprises a support seat fixedly mounted on the connecting shaft and a swing seat mounted in cooperation with the support seat, and the pin is mounted on the swing seat.

[0007] A compression spring is arranged between the supporting seat and the swinging seat.

[0008] The pin swing device is a pin control cam that is hollowly sleeved on the main shaft. A rolling bearing that can press on the curved surface of the pin control cam is installed on the swing member. The pin swing mechanism can swing through the rotation of the pin control cam.

[0009] The main shaft is also provided with an upper belt control cam located on one side of the pin control cam and used to adjust the position of the upper belt. One side of the upper belt is provided with a belt adjustment assembly that is installed in cooperation with the upper belt adjustment mounting seat. The belt adjustment assembly is provided with a pressure wheel that cooperates with the upper belt control cam. The upper belt control cam can drive the belt adjustment assembly to move and thereby adjust the position of the upper belt.

[0010] The connecting rod mechanism comprises a connecting seat hinged on the main shaft, a swing arm hinged on the outer side of the wall panel, and a connecting plate hinged between the connecting seat and the swing arm.

[0011] The angle adjustment mechanism is a swing cam installed on the outside of the wall panel, and a roller that cooperates with the swing cam is installed on the swing arm. The swing cam can enable the connecting rod mechanism to drive the main shaft to rotate so that the pin angle of the pin mechanism changes.

[0012] The wall panel is provided with a power gear which is loosely mounted on the main shaft and can drive the pin swing device and the upper belt control cam 17 to move synchronously, a pair of transition gears which cooperate with the power gear, and an indentation shaft gear which cooperates with the pair of transition gears and is installed through an indentation shaft.

[0013] The pin is installed on the swing seat through the pin sleeve.

[0014] The advantages of the present invention are:

[0015] (1) By setting up the mutually coordinated pin insertion mechanism, pin insertion swing device and angle adjustment mechanism, the pin insertion mechanism can be driven by the pin insertion swing device to swing to the position of the flat rope handle to complete the flat rope handle transportation. At the same time, the angle adjustment mechanism is used to adjust the swing needle position so that the pin can accurately pierce the flat rope handle. This structural design uses the pin insertion mechanism to transport the flat rope handle, effectively avoiding the problem of missing grasping and accurately grasping the position, thereby ensuring that the flat rope handle can be accurately and stably transported.

[0016] (2) The ingenious structural design of the pin structure can swing relative to the main shaft by using the pendulum and the pin swing device under the support of the main shaft, so that the swing position is accurate, realizing the reliable transportation of the flat rope handle. At the same time, the swing position can be fine-tuned by designing a support seat and a swing seat with a compression spring, further improving the accuracy of the pin swing.

[0017] (3) By providing an upper belt control cam for adjusting the position of the upper belt and a belt adjustment assembly installed in cooperation with the upper belt adjustment mounting seat, the position of the upper belt can be adjusted, thereby preventing the flat rope handle from hitting the belt during transportation, thereby improving the reliability of transportation.

[0018] (4) The designed angle adjustment mechanism can directly drive the main shaft to rotate, so that the insertion angle of the pin mechanism is changed to achieve accurate insertion of the pin. The control method is simple and the action is reliable, which effectively ensures the stability and reliability of the flat rope handle transportation and avoids the occurrence of problems such as inadequate flat rope transportation and flat rope blockage, which affect the stable operation of the machine.

[0019] (5) The pin swing device and the angle adjustment mechanism are controlled separately by a complete transmission mechanism consisting of a power gear, a transition gear matched with the gear, and an indentation shaft gear matched with the transition gear. The complete set of unified transmission mechanisms enables good synchronization of power output, further ensuring the reliability of use. BRIEF DESCRIPTION OF THE DRAWINGS

The rotation of the pin control cam can drive the connecting shaft to swing, so that the pin swings to the position of the flat rope handle, and the delivery of the flat rope handle is completed. The wall panel 10 is also provided with an angle adjustment mechanism 4 for adjusting the swing angle of the pin mechanism and a connecting rod mechanism 28 cooperating with the angle adjustment mechanism 4, as shown in FIG. Figure 5 As shown, the connecting rod mechanism 28 includes a connecting seat 20 hinged on the main shaft 1 through a pin, a swing arm 21 hinged on the outside of the wall panel through a pin, and a connecting plate 22 hinged between the connecting seat 20 and the swing arm 21. The angle adjustment mechanism 4 is a swing cam installed on the outside of the wall panel through an indentation shaft. The swing cam has a cam groove, and the indentation shaft also has an indentation shaft gear for power input. A roller 23 located in the cam groove is installed on the swing arm 21. The swing arm 21 rotates around the pin, and under the guidance of the roller 23, the swing arm 21 drives the connecting plate 22 to swing, thereby driving the main shaft to rotate to change the angle of the pin of the pin mechanism, thereby making the pin 8 face the flat rope handle.

[0028] Furthermore, the pin installation assembly 9 includes a support seat 12 fixedly mounted on the connecting shaft and a swing seat 13 installed in cooperation with the support seat. A copper sleeve sleeved on the connecting shaft is also installed in the swing seat 13. The pin 8 is installed on the swing seat 13. A compression spring 14 is installed between the support seat 13 and the swing seat 13 by means of screws, thereby the swing position of the pin can be fine-tuned by means of the compression spring. The pin is installed on the swing seat 13 by means of a pin sleeve. Specifically, the pin sleeve is fixedly mounted on the swing seat 13, and the pin is installed in the pin sleeve. The position of the pin in the pin sleeve can be adjusted to achieve the depth of the pin penetrating into the flat rope handle.

[0029] Furthermore, the spindle 1 is also provided with an upper belt control cam 17 located on one side of the pin control cam for adjusting the position of the upper belt 16. Specifically, the pin control cam and the upper belt control cam can be mounted on the spindle 1 through a bearing, and a belt adjustment assembly 18 is provided on one side of the upper belt 16 to be mounted in cooperation with the upper belt adjustment mounting seat, and a pressure wheel 19 is provided on the belt adjustment assembly 18 to cooperate with the upper belt control cam 17.

Therefore, the upper belt control cam 17 can drive the belt adjustment assembly to lift the upper belt to achieve the purpose of adjusting the position of the upper belt, making it convenient to insert the pin to move the flat rope handle out.

[0030] Furthermore, the wall panel 10 is equipped with a power gear 24 which is hollowly mounted on the main shaft 1 and can drive the pin control cam and the upper belt control cam 17 to move synchronously, a pair of transition gears 25 which cooperate with the power gear 24, and an indentation shaft gear 26 which cooperates with the pair of transition gears 25 and is installed through an indentation shaft 27. The indentation shaft is installed in cooperation with the angle adjustment mechanism 4. The indentation shaft gear 26 can provide input power to the angle adjustment mechanism 4 and transmit the power to the power gear 24 at the same time. Since the power gear 24 is installed in cooperation with the upper belt control cam 17 and the pin control cam, the pin control cam and the upper belt control cam 17 can be driven to rotate. In addition, one rotation of the swing cam corresponds to a flat rope handle for transmission, that is, the pin is inserted into the flat rope handle under the control of the swing cam, and the swing cam controls the rotation speed of the pin.
