Several mounting seats are connected to the surface of the mounting beam, and a set of mounting seats is connected to a reduction motor. The output shaft of the reduction motor is connected to a first transmission wheel. The mounting seats are rotatably connected to a transmission shaft via bearing seats.

Description

Technical Field

[0001] This utility model belongs to the field of automatic winding machine technology, specifically relating to a double-headed cylinder support structure for the extension mechanism of an automatic winding machine. Background Technology

[0002] In the industrial production field, especially in industries involving the processing of roll materials, such as film, paper, and metal foil, automatic winding machines are one of the key pieces of equipment. Their function is to wind up the produced roll materials according to certain specifications and requirements for subsequent storage, transportation, and use. The extension mechanism, as an important component of the automatic winding machine, is responsible for accurately extending and retracting the winding shaft, working in conjunction with the unwinding device to complete the winding action of the roll material.

[0003] In existing automatic winding machines, the double-headed cylinders of the extension mechanism play a crucial role in providing power. These cylinders are typically mounted inside the machine via fixed brackets. However, early automatic winding machine extension mechanisms were relatively simple in design, with fixed bracket structures that made it difficult to flexibly adjust to different roll specifications and winding processes. This resulted in poor winding performance when winding rolls of varying widths, thicknesses, or materials. For example, when winding wider rolls, the inability of the extension mechanism to accurately position and adjust them led to uneven winding, affecting product appearance and potentially causing quality issues in subsequent use. Conversely, when winding thinner rolls, insufficient bracket stability could cause excessive compression or stretching during winding, damaging the roll's physical properties. Utility Model Content

[0004] The purpose of this utility model is to provide a double-headed cylinder support structure for the extension mechanism of an automatic winding machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-headed cylinder support structure for the extension mechanism of an automatic winding machine, comprising:

[0006] The mounting beam has several mounting seats connected to its surface. A set of mounting seats has a geared motor connected to its surface. The output shaft of the geared motor is connected to a first transmission wheel. The mounting seats are rotatably connected to each other through bearing seats, and a transmission shaft is used to drive the conveyor belt inside the mounting seat to rotate.

[0007] The bracket has two sets, which are respectively located at both ends of the mounting beam. An adjusting cylinder is installed at the bottom of the bracket, and two sets of positioning blocks are connected to the top of the bracket.

[0008] Preferably, a positioning baffle is provided between the two sets of positioning blocks, and one end of the positioning baffle is connected to the mounting beam.

[0009] Preferably, the piston rod of the adjusting cylinder is connected to the mounting beam, and a fixing block is connected to one side of the bracket.

[0010] Preferably, one end of the drive shaft is connected to a first driven wheel, and the first drive wheel and the first driven wheel are connected by a drive belt.

[0011] Preferably, a plurality of second transmission wheels are fixedly sleeved on the surface of the transmission shaft, and a second driven wheel is rotatably connected to the mounting base via a bearing.

[0012] Preferably, the second drive wheel and the second driven wheel are connected by a conveyor belt.

[0013] Preferably, a roll insert plate is connected to the top of the mounting base.

[0014] Preferably, the surface of the fixing block is provided with a plurality of mounting holes.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) By adjusting the cylinder, positioning block, and positioning baffle, the accuracy of the extension mechanism is significantly improved. The piston rod of the adjusting cylinder is connected to the mounting beam, which can accurately control the position of the mounting beam. When winding different specifications of rolls, the extension length and angle of the extension mechanism can be flexibly adjusted by adjusting the cylinder according to the width, thickness and other parameters of the roll. The two sets of positioning blocks and positioning baffles at the top of the bracket cooperate with each other to accurately limit the position of the extension mechanism during its movement. When the extension mechanism reaches the preset winding position, the positioning block and the positioning baffle contact each other to ensure that the position height of the extension mechanism is consistent each time it is wound, effectively avoiding the problem of uneven winding of the roll, greatly improving the winding quality, ensuring that the appearance of the wound roll is flat and the size is standardized, and reducing the product defect rate caused by winding problems.

[0017] (2) The geared motor converts electrical energy into mechanical energy and outputs stable torque and speed. The first drive wheel connected to its output shaft is connected to the first driven wheel at one end of the drive shaft through the drive belt. Several second drive wheels fixedly sleeved on the surface of the drive shaft are connected to the second driven wheel in the mounting seat through the conveyor belt, which further transmits power to each conveyor belt, ensuring the synchronicity and stability of the conveyor belt operation and providing a strong guarantee for the smooth winding of the roll material.

[0021] 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.

[0022] This utility model provides, for example Figure 1-2 The automatic winding machine head extension mechanism double-cylinder support structure shown includes:

[0023] Mounting beam 1, the surface of which is connected to several mounting seats 2, one set of mounting seats 2 is connected to a reduction motor 3, the output shaft of the reduction motor 3 is connected to a first transmission wheel 4, and the several mounting seats 2 are rotatably connected to each other through bearing seats 5 by a transmission shaft 7 for driving the conveyor belt 6 inside the mounting seat 2 to rotate.

[0024] The bracket 8 has two sets, which are respectively located at both ends of the mounting beam 1. The bottom of the bracket 8 is equipped with an adjusting cylinder 9, and the top of the bracket 8 is connected to two sets of positioning blocks 10.

[0025] A positioning baffle 11 is provided between the two sets of positioning blocks 10, and one end of the positioning baffle 11 is connected to the mounting beam 1. When the mounting beam 1 moves to the preset winding position, the positioning block 10 contacts the positioning baffle 11, restricting the further movement of the mounting beam 1, and ensuring that the extension mechanism extends and retracts accurately each time.

[0026] One end of the drive shaft 7 is connected to a first driven wheel 14, and the first drive wheel 4 and the first driven wheel 14 are connected by a drive belt 15.

[0027] A plurality of second drive wheels 16 are fixedly sleeved on the surface of the drive shaft 7. A second driven wheel 17 is rotatably connected to the mounting base 2 through a bearing. The second drive wheels 16 and the second driven wheels 17 are connected by a conveyor belt 6. The plurality of second drive wheels 16 are fixedly sleeved on the surface of the drive shaft 7. Each second drive wheel 16 is connected to the corresponding second driven wheel 17 through the conveyor belt 6. This structural design ensures that the second driven wheels 17 in each mounting base 2 can rotate synchronously.

[0028] The top of the mounting base 2 is connected to a roll insert plate 18.

[0029] The piston rod of the adjusting cylinder 9 is connected to the mounting beam 1. A fixing block 12 is connected to one side of the bracket 8. The surface of the fixing block 12 is provided with several mounting holes 13. The mounting holes 13 are key components for connecting the fixing block 12 to the winding machine frame. By passing bolts through the mounting holes 13, the fixing block 12 can be securely installed on the winding machine frame.

[0030] The automatic winding machine's head extension mechanism has a double-headed cylinder support structure. When the automatic winding machine is started, the reduction motor 3 is powered on and begins to work. The output shaft of the reduction motor 3 drives the first transmission wheel 4 to rotate. The first transmission wheel 4 is connected to the first driven wheel 14 through the transmission belt 15. The friction of the transmission belt 15 is used to smoothly transmit the power to the transmission shaft 7, causing the transmission shaft 7 to start rotating. The second transmission wheel 16, which is fixedly sleeved on the surface of the transmission shaft 7, rotates together with the transmission shaft 7. The second transmission wheel 16 is then connected to the second driven wheel 17 through the conveyor belt 6, further transmitting the power to the conveyor belt 6 in the mounting base 2, driving the conveyor belt 6 to rotate, and providing power support for the conveying and winding of the roll material.

[0031] Before the winding operation, the control system sends a command to the regulating cylinder 9 according to the specifications of the roll material and the winding process requirements. Since the regulating cylinder 9 is a double-headed cylinder, the piston inside the regulating cylinder 9 can push the piston rods at both ends to extend or retract under the action of compressed air. Since the piston rod is connected to the mounting beam 1, the extension and retraction of the piston rod can drive the mounting beam 1 to move, thereby realizing the extension and retraction of the extension mechanism. In this process, the positioning block 10 and the positioning baffle 11 at the top of the bracket 8 play an important role. When the mounting beam 1 moves, the positioning block 10 moves with the mounting beam 1. When the mounting beam 1 moves to the preset winding position, the positioning block 10 contacts the positioning baffle 11, restricting the further movement of the mounting beam 1, ensuring that the extension and retraction position of the extension mechanism is accurate each time, and realizing precise control of the winding position.

[0032] During the operation of the conveyor belt 6, the roll material placed on the roll material insert plate 18 begins to be conveyed. The movement of the conveyor belt 6 smoothly pushes the roll material to the winding area, and in conjunction with the unwinding device, completes the winding operation of the roll material.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
