Description

Technical Field

[0001] The present invention relates to the technical field of film winding and plugging equipment, and particularly to a film winding and plugging mechanism. Background Art

[0002] After the film winding is completed, it generally needs to be packaged. After wrapping the packaging film around the outside of the film roll, the two ends need to plug the packaging film into the inside of the drum of the film roll. Currently, the general method is to manually plug the packaging film into the drum through a plug rod, with low efficiency. There is also a method of combining manual labor and a cylinder for plugging. The worker holds the film roll, and the cylinder plugs it. In this way, it is difficult to control the magnitude of the force. If the force is too large, it will cause the end of the drum to burst, thus affecting production. Therefore, there is an urgent need for an improved technology to solve the above problems existing in the prior art. Summary of the Invention

[0003] The purpose of the present invention is to provide a film winding and plugging mechanism. Both of the two film clamping and plugging mechanisms clamp the two ends of the wound film through the first clamping jaw and the second clamping jaw respectively, and then the plugging cylinder plugs the packaging at the end into the drum of the wound film. On the one hand, it has high efficiency, saves labor costs and labor intensity. On the other hand, through the cooperation of the first clamping jaw and the second clamping jaw, it is ensured that the drum of the wound film will not burst during film plugging, thus ensuring the quality of the product, so as to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A film winding and plugging mechanism, comprising a base and a film clamping and plugging mechanism;

[0005] Pulley wheels are symmetrically arranged at both ends of the upper surface of the base. The two pulley wheels are connected by a synchronous belt. A servo motor is arranged at any one end of the lower surface of the base. The servo motor is connected to the corresponding pulley wheel. A first linear guide rail is arranged along the length direction on the upper surface of the base;

[0006] There are two film clamping and plugging mechanisms, which are symmetrically arranged at both ends of the base. One of the film clamping and plugging mechanisms is connected to one side of the synchronous belt through a connecting piece, and the other film clamping and plugging mechanism is connected to the other side of the synchronous belt through a connecting piece. The two film clamping and plugging mechanisms are respectively connected to the diagonal lines of the synchronous belt through connecting pieces, so that the two film clamping and plugging mechanisms move synchronously and in opposite directions;

[0007] The film clamping and plugging mechanism includes a sliding seat, a film plugging cylinder, a first sliding plate, a second sliding plate, a first clamping jaw and a second clamping jaw. The sliding seat is connected to a first linear guide rail. A film plugging cylinder is arranged outside the sliding seat through a bracket. Second linear guide rails are symmetrically arranged on both sides of the upper surface of the sliding seat. A first pushing cylinder and a second pushing cylinder are arranged on both sides of the sliding seat in opposite directions. The first pushing cylinder and the second pushing cylinder are respectively arranged on the diagonal lines of the sliding seat. The first pushing cylinder is connected to the first sliding plate, and the second pushing cylinder is connected to the second sliding plate. The first sliding plate and the second sliding plate are both connected to the second linear guide rail and are respectively located at both ends of the sliding seat. The upper surface of the first sliding plate is connected to a plurality of first clamping jaws through a first connecting frame, and gaps are left between adjacent first clamping jaws. The upper surface of the second sliding plate is connected to a plurality of second clamping jaws through a second connecting frame, and gaps are left between adjacent second clamping jaws. The first clamping jaws and the second clamping jaws are arranged in an interleaved manner, and the gaps between the first clamping jaws and the second clamping jaws correspond to each other one by one, and the gaps between the second clamping jaws and the first clamping jaws correspond to each other one by one;

[0008] The first clamping jaw and the second clamping jaw have the same structure. Semi-circular grooves are opened at one end of the first clamping jaw and the second clamping jaw close to each other. When the first clamping jaw and the second clamping jaw are inserted in an interleaved manner, the film plugging cylinder, the semi-circular groove opened on the first clamping jaw and the semi-circular groove opened on the second clamping jaw are located on the same axis, so as to ensure that when the film roll is clamped by the first clamping jaw and the second clamping jaw, the film plugging cylinder and the film roll are coaxial, thereby ensuring that the piston of the film plugging cylinder is inserted into the core of the film roll.

[0009] Preferably, for a film winding and plugging mechanism provided by the present invention, the first linear guide rail and the second linear guide rail are vertically arranged in the horizontal direction to ensure that the two film clamping and plugging mechanisms correspond to each other and can cooperate with both ends of the film roll.

[0010] Preferably, for a film winding and plugging mechanism provided by the present invention, the film plugging cylinders of the two film clamping and plugging mechanisms are located on the same axis to ensure that they are located on the axis of both ends of the film roll to be plugged with film.

[0011] Preferably, for a film winding and plugging mechanism provided by the present invention, the width of the gap between adjacent first clamping jaws is greater than the width of the second clamping jaw to ensure that the first clamping jaw can be inserted into the gap between two adjacent second clamping jaws, and the width of the gap between adjacent second clamping jaws is greater than the width of the first clamping jaw to ensure that the second clamping jaw can be inserted into the gap between two adjacent first clamping jaws.

[0012] Preferably, for a film winding and plugging mechanism provided by the present invention, its usage method includes the following steps:

[0013] Step 1: According to the length of the film roll, start the servo motor to drive the synchronous belt to rotate, so that the two film clamping and plugging mechanisms move synchronously in opposite directions to determine the distance between the two film clamping and plugging mechanisms.

[0014] Step 2: Control the first pushing cylinder and the second pushing cylinder, and extend the pistons of the first pushing cylinder and the second pushing cylinder to push the first sliding plate and the second sliding plate outwards, so as to separate the first clamping jaw and the second clamping jaw. Then, place the two ends of the film roll with the packaging film between the corresponding first clamping jaw and the second clamping jaw respectively.

[0015] Step 3: Control the first pushing cylinder and the second pushing cylinder, and retract the pistons of the first pushing cylinder and the second pushing cylinder to retract the first sliding plate and the second sliding plate inwards, so as to interleave and plug the first clamping jaw and the second clamping jaw, and fix the two ends of the film roll between the corresponding first clamping jaw and the second clamping jaw.

[0016] Step 4: Start the film plugging cylinder, and extend the piston of the film plugging cylinder. Push the packaging at both ends of the film roll into the inside of the reel through the piston of the film plugging cylinder.

[0017] Step 5: Retract the piston of the film plugging cylinder, separate the first clamping jaw and the second clamping jaw, and then take out the film roll.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) By clamping both ends of the wound film by the first clamping jaw and the second clamping jaw respectively in the two film clamping and plugging mechanisms, and then pushing the packaging at the end into the reel of the wound film through the film plugging cylinder, on the one hand, it has high efficiency, saves labor costs and labor intensity, and on the other hand, through the cooperation of the first clamping jaw and the second clamping jaw, it is ensured that the reel of the wound film will not burst during film plugging, thus ensuring the product quality.

[0020] (2) Since the two film clamping and plugging mechanisms are respectively connected to the diagonal lines of the synchronous belt through connectors, and one servo motor is used to achieve synchronous reverse movement. On the one hand, the synchronism of the two film clamping and plugging mechanisms is ensured, and on the other hand, only one motor is needed, saving costs.

[0021] (3) The structure is simple, which is convenient for assembly and disassembly, thus facilitating later maintenance, servicing and replacement of components. Brief Description of the Drawings

[0032] Its usage method includes the following steps:

[0033] Step 1: According to the length of the film roll, start the servo motor 4 and drive the synchronous belt 3 to rotate, so that the two film clamping and plugging mechanisms move synchronously in the opposite direction to determine the distance between the two film clamping and plugging mechanisms;

[0034] Step 2: Control the first pushing cylinder 15 and the second pushing cylinder 16, and make the pistons of the first pushing cylinder 15 and the second pushing cylinder 16 push out, so that the first sliding plate 9 and the second sliding plate 10 are pushed outwards, thereby separating the first claw 11 and the second claw 12, and then place the two ends of the film roll with the packaging film between the corresponding first claw 11 and second claw 12 respectively;
