Description

Technical Field

[0001] The utility model relates to the technical field of film or sheet material processing equipment, in particular to a tension isolation device for a high-strength flame-retardant sandwich mesh air-molded substrate. Background Art

[0002] The production process of polyvinyl chloride film and sheet is: batching - mixing - internal kneading - two times of two-roller open kneading - filtering by filter - five-roller calendering - taking-up by take-up wheel - embossing by embossing wheel - shaping by cooling wheel - winding - packaging.

[0003] From the five-roll calender to the winding process, the linear speed of the wheel in each process increases continuously to maintain a certain tension to achieve traction. Less tension is required at the front end to ensure that the film fits the cooling wheel group (to achieve the purpose of reducing water bath shrinkage); and winding requires greater tension to ensure the flatness of the winding. During the five-roll calender forming-taking wheel taking-up-embossing wheel embossing-cooling wheel shaping stages, the film material has not been completely cooled. Excessive tension will cause large shrinkage of the film material in the water bath and difficulty in controlling the thickness. Maintaining a stable and large tension in the winding stage has a greater benefit effect on the flatness of the film material, so a larger tension is required. At present, there is no effective partition between the various processes, and the linear speed and abnormal fluctuations affect each other. It is difficult to take into account both the flatness of the winding and the control of water bath shrinkage and thickness at the same time. Utility Model Content

[0004] In view of the defects existing in the prior art, the purpose of the utility model is to provide a tension isolation device for a high-strength flame-retardant mesh air-formed substrate, so as to solve the problem that the existing polyvinyl chloride film or sheet has difficulty in taking into account both the winding flatness and the control of water bath shrinkage and thickness at the same time due to the lack of effective tension isolation during the winding stage.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] Furthermore, the lifting drive mechanism includes a driving motor, a pair of bevel gear transmission groups, a transmission shaft and a pair of ball screw transmission assemblies. The pair of bevel gear transmission groups are respectively arranged at the top ends of a pair of machine bases, the output shaft of the driving motor is connected to a bevel gear transmission group, the transmission shaft is horizontally arranged above the rubber roller, the two ends of the transmission shaft are respectively connected to a pair of bevel gear transmission groups, a pair of ball screw transmission assemblies are respectively arranged on a pair of machine bases, the screw in each ball screw transmission group is respectively installed on the machine base for vertical rotation, the top ends of the screw are respectively connected to the bevel gear transmission groups, the screw nuts in the ball screw transmission group are respectively installed on the screw, and the screw nuts are respectively fixedly connected to the lifting slide plates.

[0008] Furthermore, a slide groove for lifting and lowering the rubber roller is formed on the machine base.

[0010] Furthermore, a pair of parallel and vertically arranged slide rails are provided on the outer end surface of the machine base, and the lifting slide plate is slidably installed on the slide rails through a sliding block provided.

[0011] The beneficial effects of the utility model are as follows: by arranging a rubber roller that can be raised and lowered above the winding roller, and utilizing the rubber roller to move downward and fit against the upper surface of the winding roller, pressure can be applied to the winding roller below. The pressure acting on the winding roller can play a role in isolating and stabilizing the tension of the film material during the winding stage and the cooling stage, and can effectively isolate the tension between the winding and cooling wheels, thereby solving the problem of simultaneously taking into account the winding flatness and controlling the shrinkage and thickness of the water bath.

DETAILED DESCRIPTION

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] See attached Figure 1 To Attachment Figure 3 As shown, this embodiment provides a tension isolation device 100 for a high-strength flame-retardant sandwich inflatable mold substrate, which includes a pair of machine bases 10 , a winding wheel 20 , a rubber roller 30 and a pressurizing assembly 40 .

[0020] A pair of machine bases 10 are arranged symmetrically, and the winding wheel 20 is horizontally arranged at the bottom of the pair of machine bases 10, and the two ends of the winding wheel 20 are respectively connected to the machine bases 10 on the left and right sides to form a rotation connection. During use, the function of the winding wheel 20 is to wind up the film or sheet.

[0021] Combined with reference to Figure 1 To Attachment Figure 3 As shown, the pressurizing assembly 40 in this embodiment includes a lifting drive mechanism 41 and a pair of lifting slides 42, the pair of lifting slides 42 are respectively mounted on a pair of machine bases 10, and each lifting slide 42 forms a vertical sliding connection with the outer side of the machine base 10, that is, the lifting slide 42 can be lifted and moved relative to the machine base 10. The lifting drive mechanism 41 is connected to the lifting slide 42 to provide power for the lifting and moving of the lifting slide 42.

[0022] Specifically, a pair of vertically arranged slide rails 60 are fixedly installed in parallel on the outer side surface of each machine base 10, and a pair of sliders 70 are correspondingly fixed on the inner side surface of the lifting slide plate 42. The lifting slide plate 42 is slidably installed on the pair of slide rails 60 on the machine base 10 through the pair of sliders 70 thereon to realize the lifting and lowering movement of the lifting slide plate 42 along the machine base 10.

[0023] Continue to refer to the attached Figure 1 To Attachment Figure 3 As shown, the rubber roller 30 is arranged in parallel just above the winding roller, and the two ends of the rubber roller 30 are rotatably mounted on the pair of lifting slides 42, so that the lifting slides 42 synchronously drive the rubber roller 30 to move up and down during the lifting and moving of the lifting slides 42 along the machine base 10. Figure 2 and attached Figure 4As shown, in order to prevent interference between the base 10 and the rubber roller 30 when the rubber roller 30 is lifted and lowered relative to the base 10, a vertically arranged slide groove 11 is formed on the base 10. When the rubber roller 30 follows the lifting slide plate 42 to lift and lower, the two ends of the rubber roller 30 are lifted and lowered in the corresponding slide groove 11 on the base 10.

[0024] Continue to refer to the attached Figure 1 To Attachment Figure 3 As shown, in this embodiment, the lifting drive mechanism 41 includes a driving motor 411, a pair of bevel gear transmission groups 412 (a pair of mutually matched bevel gears), a transmission shaft 413, and a pair of ball screw transmission assemblies 414. The driving motor 411 is installed on the left side of the machine base 10, and the driving motor 411 is fixedly installed at the top of the left side of the machine base 10 through the motor mounting seat 50 provided. The pair of bevel gear transmission groups 412 are arranged on the left and right sides of the machine base 10 respectively, and the bevel gear transmission group 412 on the left side is connected to the output shaft of the driving motor 411, that is, the power of the driving motor 411 is first output to the bevel gear transmission group 412 on the left side of the machine base 10. At the same time, since the pair of bevel gear transmission groups 412 are connected through the transmission shaft 413, the power of the bevel gear transmission group 412 on the left side of the machine base 10 can be directly output to the bevel gear transmission group 412 on the right side of the machine base 10 through the transmission shaft 413, so as to achieve the output power synchronization of the bevel gear transmission groups 412 on the left side of the machine base 10 and the right side of the machine base 10. By using the transmission shaft 413 to directly transmit the output power of the bevel gear transmission group 412 on one side to the bevel gear transmission group 412 on the other side, this structural form can use only a single power source to reduce the investment in equipment cost.

[0025] See attached Figure 2 and attached Figure 4 As shown, in this embodiment, the ball screw transmission assembly 414 includes a screw 4141 and a screw nut 4142 mounted on the screw 4141. The top end of the screw 4141 on each base 10 is correspondingly connected to the bevel gear transmission group 412 thereon. It can be understood that the function of the bevel gear transmission group 412 in this embodiment is to convert the output power in the horizontal direction and the vertical direction.

[0026] For example, the screw rod 4141 on the left machine base 10 is connected to the bevel gear transmission group 412, and the output power of the drive motor 411 can be directly transmitted to the screw rod 4141 on the left machine base 10 to drive it to rotate. At the same time, the transmission power of the drive motor 411 is converted into a horizontal rotation power output through the bevel gear transmission group 412 on the left machine base 10. The horizontal output power drives the rotation of the transmission shaft 413 to transmit the power to the bevel gear transmission group 412 on the right machine base 10, and the horizontal rotation power is converted into a vertical rotation power through the bevel gear transmission group 412 on the right machine base 10. The power output of the straight horizontal rotation drives the screw rod 4141 connected to the bevel gear transmission group 412 on the right machine base 10 to rotate, so that the screw rods 4141 on the left and right machine bases 10 are in a synchronous rotational motion, and the screw rod 4141 in the rotational motion state drives the screw nut 4142 thereon to rise or fall, and the screw nut 4142 in the rising or falling state drives the lifting slide 42 connected thereto to rise or fall synchronously, and the lifting slide 42 in the rising or falling state drives the rubber roller 30 to rise or fall synchronously, so as to achieve the separation or compression of the winding roller below. In some embodiments, a driving cylinder can also be installed on the left machine base 10 and the right machine base 10 respectively, and the driving cylinder is directly connected to the two ends of the rubber roller 30 by the driving cylinder, so as to drive the rubber roller 30 to move up and down, so as to achieve the coordination with the winding wheel 20 below.

[0027] In order to better understand the tension partition device for the high-strength flame-retardant sandwich mesh inflatable mold substrate in this embodiment, the working principle thereof is briefly described below:

[0028] When the winding roller is winding the plastic film or sheet, in order to effectively isolate the tension between the winding roller and the cooling roller, the driving motor 411 drives the screw 4141 located on the left machine base 10 and the right machine base 10 to rotate, and the rotating screw 4141 then drives the screw nut 4142 thereon to move downward, and the downward moving screw nut 4142 then synchronously drives the lifting slide 42 fixedly connected to it to move downward, and the downward moving lifting slide 42 then drives the rubber roller 30 to move downward until the rubber roller 30 is pressed tightly against the upper surface of the winding roller below, exerting pressure on the plastic film or sheet entering the outer surface of the winding roller, and effectively isolating the tension between the winding and cooling wheels, so as to solve the problem of taking into account both the winding flatness and the control of water bath shrinkage and thickness at the same time.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
