Description

Technical Field

[0001] This utility model relates to the field of blown film machine technology, specifically to an automatic glue-applying blown film machine winding mechanism. Background Technology

[0002] The winding mechanism of a blown film machine is a key piece of equipment on the blown film production line used to wind up the finished film. Its core components include a support, an active take-up roller, and a winding roller. During the winding process, glue or double-sided tape needs to be applied to the surface of the air shaft (spare shaft) to ensure that the starting end of the film is firmly fixed and to ensure the winding quality.

[0003] Currently, the application of adhesive to the air shafts is generally done manually: operators must manually apply adhesive to the air shafts before winding them up, and then assemble them into the winding mechanism. This manual operation mode not only consumes a lot of manpower and time, but also makes it difficult to consistently control the uniformity and accuracy of the adhesive application, which can easily affect the subsequent winding quality due to operational differences. At the same time, manual operation requires the pre-winding time of the winding process, which limits the overall operating efficiency of the winding mechanism and cannot meet the high-efficiency production requirements of automated production lines.

[0004] Therefore, there is an urgent need for a blown film machine winding mechanism technology that can achieve automatic glue application on the air shaft and reduce manual intervention, in order to solve the problems of time-consuming, labor-intensive and inefficient manual operation.

[0005] To address the shortcomings in the prior art, this utility model provides an automatic adhesive-coating blown film machine winding mechanism.

[0006] The technical solution adopted by this utility model is: an automatic glue-applying blown film machine winding mechanism, including a support, an active take-up roller and a take-up roller, and also including a spare support plate and a glue-applying mechanism;

[0007] The spare support plates are installed on both sides of the bracket and are used to place the spare shaft;

[0008] The glue application mechanism includes a glue spraying pressure tank, a linear track module, an automatic dispensing machine, a lifting mechanism, and a dispensing head. The glue spraying pressure tank, the automatic dispensing machine, and the dispensing head are connected by pipes. The linear track module is connected to the lifting mechanism to drive the spare shaft of the lifting mechanism to reciprocate along its length. The lifting mechanism is connected to the dispensing head to drive the dispensing head to reciprocate towards or away from the spare shaft.

[0009] Furthermore, the lifting mechanism includes a motor housing fixedly connected to the output end of the linear track module, a servo motor disposed within the motor housing, a drive screw connected to the servo motor via a pulley, a screw block threadedly connected to the drive screw, a mounting plate fixedly connected to the screw block, and a dispensing head mounting block fixedly connected to the mounting plate, wherein the dispensing head is fixedly mounted on the dispensing head mounting block.

[0010] Furthermore, a screw housing is provided on the motor housing, a guide rail is provided on the bottom wall of the screw housing, and a guide block is provided on the back of the screw block that slides with the guide rail.

[0011] Furthermore, the spare support plate is rotatably connected to the bracket, with a positioning notch for placing the spare shaft at one end and a drive cylinder for driving the spare support plate to rotate at the other end.

[0012] Furthermore, the automatic dispensing machine is fixed to the motor housing, and is equipped with a pressure regulating valve, a pressure gauge, and control buttons.

[0013] Furthermore, the adhesive spraying pressure tank is fixed to the top of the bracket.

[0014] The beneficial effects of this utility model are:

[0015] 1. Improve operational efficiency and reduce manual intervention: By setting up a glue application mechanism, the automatic glue application of the air shaft (spare shaft) is realized, replacing the traditional manual glue application or adhesive application operation, which greatly shortens the air shaft pretreatment time, avoids the delay of the winding process caused by manual operation, and significantly improves the overall operational efficiency of the winding mechanism; at the same time, it reduces reliance on manual labor and reduces labor cost input.

[0016] 2. Ensure stable glue coating quality: The linear track module drives the dispensing head to reciprocate along the length of the spare shaft, and the lifting mechanism precisely controls the distance between the dispensing head and the spare shaft. The two work together to make the glue coating trajectory, glue quantity uniformity and glue coating position more precise and controllable, avoiding problems such as uneven glue coating and position deviation caused by manual operation, ensuring the reliability of the fixed starting end of the subsequent film winding and improving the winding quality.

[0017] 3. Optimize operational convenience and continuity: Spare support plates on both sides of the bracket can be pre-placed with spare shafts (or can be used in conjunction with the automatic upper and lower roller mechanism to receive the automatic upper roller), and the spare shafts on the spare support plates can be pre-processed directly, which facilitates quick switching to use the pre-processed spare shafts and further improves the continuity of the winding process; the overall structural design is compatible with the core components of the existing winding mechanism, has strong compatibility, and is easy to promote and apply.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0027] This utility model provides an automatic glue-applying blown film machine winding mechanism.

[0028] In this embodiment, refer to Figure 1-4 The automatic glue-applying blown film machine winding mechanism includes a support 1, an active take-up roller 2 and a take-up roller 3, as well as a spare support plate 4 and a glue-applying mechanism.

[0029] The spare support plates are installed on both sides of the bracket and are used to place the spare shaft;

[0030] The glue application mechanism includes a glue spraying pressure tank 5, a linear track module 6, an automatic dispensing machine 7, a lifting mechanism 8, and a dispensing head 9. The glue spraying pressure tank 5, the automatic dispensing machine, and the dispensing head are connected by a pipe 10. The linear track module is connected to the lifting mechanism to drive the spare shaft of the lifting mechanism to reciprocate along its length. The lifting mechanism is connected to the dispensing head to drive the dispensing head to reciprocate towards or away from the spare shaft.

[0031] In the above technical solution, based on the traditional blown film machine winding mechanism, a spare support plate and a glue coating mechanism are added: the spare support plate is positioned on both sides of the bracket to provide a place for the spare shaft (air expansion shaft); in the glue coating mechanism, the glue spraying pressure tank stores and transports glue, which is then piped to the automatic glue dispensing machine and glue dispensing head. The linear track module drives the lifting mechanism to reciprocate along the length of the spare shaft, and the lifting mechanism controls the glue dispensing head to move closer to / away from the spare shaft. The three work together to achieve glue coating on the surface of the spare shaft.

[0032] Thus, it replaces manual gluing, significantly reduces human intervention, shortens the pre-processing time of the spare shaft, and improves the overall efficiency of the winding mechanism; mechanical drive ensures stable gluing trajectory, avoids uneven glue application and positional deviation problems caused by manual operation, and ensures winding quality; the spare support plate stores the spare shaft, enabling parallel operation of gluing and winding, and improving process continuity.

[0033] Specifically, the lifting mechanism includes a motor housing 11 fixedly connected to the output end of the linear track module, a servo motor 12 disposed inside the motor housing 11, a drive screw 14 driven and connected to the servo motor via a pulley 13, a screw block 15 threadedly connected to the drive screw 14, a mounting plate 16 fixedly connected to the screw block 15, and a dispensing head mounting block 17 fixedly connected to the mounting plate 16, wherein the dispensing head is fixedly mounted on the dispensing head mounting block.

[0034] In this embodiment, the motor housing is fixedly connected to the linear track module to achieve overall translation. The servo motor inside the housing drives the screw to rotate through the pulley. The screw and the screw block are threaded together to convert the rotational motion into linear motion. The screw block drives the mounting plate and the dispensing head mounting block to rise and fall, ultimately achieving precise lifting and lowering of the dispensing head.

[0035] Employing a servo motor ensures high driving precision, and combined with threaded transmission, it achieves precise control over the lifting distance of the dispensing head, ensuring uniform adhesive layer thickness.

A guide rail is provided on the bottom wall of the screw housing, and a guide block is provided on the back of the screw block. The guide block and the guide rail slide together to form a composite motion constraint structure of "screw drive + guide rail guidance". The guide rail restricts the rotation of the screw block, ensuring that the screw block only moves up and down along the axial direction, avoiding the dispensing head offset and improving the accuracy of the dispensing position.

[0038] Specifically, the spare support plate is rotatably connected to the bracket. One end of the spare support plate is provided with a positioning notch 21 for placing the spare shaft, and the other end is provided with a drive cylinder 22 for driving the spare support plate to rotate.

[0039] In this embodiment, the spare support plate is rotatably connected to the bracket. One end is set with a positioning notch to achieve precise positioning of the spare shaft, and the other end is connected to the drive cylinder. The spare support plate is rotated around the rotation point by the extension and retraction of the cylinder piston rod, which is used to automatically transfer the glued spare shaft to the active take-up roller as a take-up roller for winding.

[0040] Specifically, the automatic dispensing machine is fixed to the motor housing and is equipped with a pressure regulating valve 23, a pressure gauge 24, and a control button 25.

[0041] In this embodiment, the automatic dispensing machine is fixed to the motor housing for follow-up, the pressure regulating valve adjusts the input glue pressure to control the dispensing volume, the pressure gauge monitors the pressure value in real time, and the control button realizes operations such as dispensing start / stop and parameter adjustment.

[0042] Specifically, the adhesive spraying pressure tank is fixed to the top of the bracket.

[0043] In this embodiment, the glue spraying pressure tank is fixed to the top of the bracket, and gravity assists in the delivery of glue. At the same time, the top installation position facilitates the pipeline layout, shortens the glue delivery path, and reduces pipeline resistance.
