Description

Technical Field

[0001] This utility model relates to the technical field of static electricity elimination equipment, specifically a physical static electricity elimination device for a dust-free packaging bag production line. Background Technology

[0002] Cleanroom packaging bags, made of plastic, are used for packaging various products in production and daily life. During the production process, the plastic material easily generates static electricity, causing dust and other impurities to adhere to the surface of the bags. This hinders the removal of static electricity using static eliminators. However, existing static eliminators still have certain shortcomings, such as:

[0003] The "Antistatic Device" application with application number CN202323364932.8 includes a lifting frame. The left and right sides of the inner wall of the lifting frame are slidably connected to the left and right sides of two mounting plates, respectively. A servo motor a drives screw a and screw b to rotate. The rotation of screw a and screw b causes the two mounting plates, two connecting plates, and two ion blowers to move closer to each other. The distance between them is adjusted according to the static electricity intensity on the surface of the plastic packaging bag. The servo motor b drives a worm gear and a worm wheel to rotate. The rotation of the worm wheel causes the connecting plates and ion blowers to adjust their angles. The antistatic angle of the ion blowers is adjusted according to the feeding angle of the plastic packaging bag.

[0004] However, during use, the angle adjustment of the ion fans on the upper and lower sides of the equipment is carried out independently by two servo motors, which cannot be adjusted synchronously at the same angle. This not only results in high operating costs but also requires high operational precision and makes it difficult to ensure the consistency of the rotation angle of the ion fans on the upper and lower sides. Consequently, it is not conducive to effectively removing static electricity from the cleanroom packaging bags, affecting the production of cleanroom packaging bags and limiting its application. In view of this, a physical static electricity elimination device for cleanroom packaging bag production lines is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a physical static electricity elimination device for a dust-free packaging bag production line, so as to solve the problems mentioned in the background art, such as high cost, high precision requirements, and difficulty in ensuring the consistency of the rotation angle of the ion fans on the upper and lower sides.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a physical static electricity elimination device for a dust-free packaging bag production line, including a fixing frame.

[0007] A sliding block is slidably connected to the inner left side of the fixed frame, and two sliding blocks are symmetrically arranged. A housing is fixedly installed on the left end face of the sliding block, and a rotating shaft is provided through the transverse bearing on the left side wall of the housing. An ion fan is fixedly installed on the left end of the rotating shaft.

[0008] The housing is provided with an angle adjustment mechanism, which is used to rotate the shaft and is connected to the inner bottom surface of the fixed frame.

[0009] The above technical solution facilitates the synchronous and same-angle adjustment of the ion fans on both the upper and lower sides.

[0010] As a preferred embodiment of this utility model, a bidirectional lead screw is installed on the inner bottom bearing of the fixing frame, and the bidirectional lead screw passes through the sliding block and is threadedly connected to the sliding block. The bidirectional lead screw bearing passes through the top of the fixing frame.

[0011] The above technical solution facilitates the movement of the housing, shaft, and ion fan by rotating the bidirectional lead screw and driving the sliding block.

[0012] As a preferred embodiment of this utility model, a first motor is fixedly installed on the top surface of the fixing frame, and the shaft end of the first motor is coaxially and fixedly connected to the top end of the bidirectional lead screw.

[0013] The above technical solution facilitates the rotation of the bidirectional lead screw by driving it with a first motor.

[0014] As a preferred technical solution of this utility model, the angle adjustment mechanism includes a rotating rod, the bottom end of which is connected to the inner bottom surface bearing of the fixed frame, and a hollow tube is movably sleeved on the outer side of the rotating rod. Two hollow tubes are symmetrically arranged, and the longitudinal bearing of the hollow tube passes through the housing. A bevel gear set is fixedly installed on the outer wall of the hollow tube, and the bevel gear set is fixedly connected to the right side of the rotating shaft.

[0015] By adopting the above technical solution, it is easy to adjust the angle of the ion fan by rotating the shaft and the ion fan through the hollow tube and the bevel gear set during rotation.

[0016] As a preferred embodiment of this utility model, the rotating rod has a square shape, and the hollow tube has an outer circle and an inner square structure that matches the rotating rod.

[0017] The above technical solution facilitates the stable and effective rotation of the hollow tube when the rotating rod rotates, while ensuring that the rotating rod and the hollow tube can move relative to each other.

[0018] As a preferred embodiment of this utility model, a connecting shaft is coaxially fixedly installed at the top end of the rotating rod, and the bearing of the connecting shaft passes through the top of the fixing frame. The top end of the connecting shaft is coaxially fixedly installed at the shaft end of the second motor, and the second motor is fixedly installed on the top surface of the fixing frame.

[0019] By adopting the above technical solution, it is convenient to drive the connecting shaft to rotate via the second motor, thereby driving the rotating rod to rotate.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the physical static electricity elimination equipment used in this dust-free packaging bag production line can rotate and adjust the angle of the ion fans on both the upper and lower sides through the same power, ensuring that the ion fans on both the upper and lower sides are adjusted synchronously and at the same angle. This not only reduces the cost of use, but also ensures the high consistency of angle adjustment, ensuring the static electricity elimination effect in the dust-free packaging bag production process, which is beneficial to the production of dust-free packaging bags. It is simple and flexible to operate and highly practical.

[0021] The first motor drives the bidirectional lead screw to rotate, causing the two sliding blocks to move in opposite directions. This allows the housings of the sliding blocks, the rotating shaft, and the ion fans to move synchronously, making it easier to adjust the distance between the ion fans according to the electrostatic intensity on the surface of the cleanroom packaging bag, thus improving the flexibility of use.

[0022] The connecting shaft is driven by a second motor to rotate, which in turn drives the rotating rod to rotate, causing the hollow tube to rotate synchronously. This, in turn, drives the rotating shaft and ion fan to rotate synchronously through a bevel gear set, achieving synchronous rotation of the ion fans on both the upper and lower sides at the same angle. This ensures the consistency of the ion fan angle adjustment and meets the requirements for effective static removal under different feeding angles of the dust-free packaging bag.

[0030] Please see Figure 1 - Figure 5 The present invention provides a physical electrostatic elimination device for a dust-free packaging bag production line, comprising a fixed frame 1, a sliding block 2 slidably connected to the inner left side of the fixed frame 1, and two sliding blocks 2 symmetrically arranged, a housing 3 fixedly installed on the left end face of the sliding block 2, and a rotating shaft 4 passing through the left side wall of the housing 3 via a transverse bearing, an ion fan 5 fixedly installed on the left end of the rotating shaft 4, an angle adjustment mechanism provided on the housing 3, the angle adjustment mechanism being used to rotate the rotating shaft 4, and the angle adjustment mechanism being connected to the inner bottom surface of the fixed frame 1.

[0031] The inner bottom surface bearing of the fixed frame 1 is equipped with a double-acting screw 6, which passes through the sliding block 2 and is threadedly connected to the sliding block 2. The bearing of the double-acting screw 6 passes through the top of the fixed frame 1.

[0032] The top surface of the fixed frame 1 is fixedly mounted with the first motor 7, and the shaft end of the first motor 7 is coaxially fixedly connected to the top end of the bidirectional lead screw 6.

[0033] The angle adjustment mechanism includes a rotating rod 8. The bottom end of the rotating rod 8 is connected to the inner bottom surface bearing of the fixed frame 1. A hollow tube 9 is movably sleeved on the outer side of the rotating rod 8. Two hollow tubes 9 are symmetrically arranged. The longitudinal bearing of the hollow tube 9 passes through the housing 3.

A bevel gear set 10 is fixedly installed on the outer wall of the hollow tube 9. The bevel gear set 10 is fixedly connected to the right side of the rotating shaft 4.
