Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology, and in particular to a PET film testing device. Background Technology

[0002] PET protective film material has advantages such as light weight, high strength, good transparency and gas barrier properties, non-toxicity, and odorlessness. PET protective film, also known as high-temperature resistant polyester film, plays an important role in many fields due to its excellent physical properties, chemical stability, dimensional accuracy, high transparency, and recyclability.

[0003] During the production of existing PET films, tensile testing machines are used to test the tensile strength of the PET films. However, when not in use and stored, these tensile testing machines are generally left exposed, leading to the accumulation of dust on the surface and affecting their operation. To address this issue, we propose a PET film testing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a PET film testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A PET film testing device includes a tensile testing machine body, an installation mechanism is installed on the top of the tensile testing machine body, and the bottom of the installation mechanism is connected to one end of a pleated sleeve. The other end of the pleated sleeve is connected to a drive frame. Guide mechanisms are fixedly connected to both sides of the drive frame, and the guide mechanisms are inserted into a second side plate. A limit mechanism is fixedly connected to the side of the second side plate.

[0006] Preferably, the mounting mechanism includes mounting bolts, a connecting plate is mounted on the top of the tensile testing machine body via the mounting bolts, and a fixing plate is fixedly connected above the connecting plate.

[0007] Preferably, the guiding mechanism includes a first side plate, both sides of the driving frame are fixedly connected to the first side plate, and a guide post is fixedly connected to the top of the first side plate.

[0008] Preferably, the guide post is cylindrical, and the second side plate has a circular hole that matches the guide post.

[0009] Preferably, a limiting plate is fixedly connected above the guide post, and the surface size of the guide post is smaller than the surface size of the limiting plate.

[0010] Preferably, the limiting mechanism includes a fixed frame, the outer side of the second side plate is fixedly connected to the fixed frame, and the outer end of the fixed frame is threaded with a push stud. The end of the push stud is connected to one side of the push plate through a bearing, and the other side of the push plate is fixedly connected to a pressing column.

[0011] Preferably, the outer side of the second side plate is provided with a round hole that matches the extrusion column, and the end surface of the extrusion column is glued with an anti-slip rubber head, and the surface of the anti-slip rubber head is provided with anti-slip texture.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The device is connected to the upper end of the tensile testing machine body by mounting bolts passing through the connecting plate and threaded connection, which facilitates the installation and fixing of the plate. At this time, by pulling the drive frame, the pleated sleeve can be easily unfolded to cover the surface of the tensile testing machine body, which facilitates dust protection of the tensile testing machine body and improves its service life. At the same time, by moving the drive frame, the first side plate can drive the guide column to move along the inside of the second side plate, which facilitates the function of limiting and guiding the drive frame.

[0013] 2. When the device moves along the second side plate via the guide column, rotating the push stud can easily push the push plate to move along the fixed frame, causing the extrusion column to drive the anti-slip rubber head through the second side plate and press against the surface of the guide column, thus limiting the guide column. At the same time, the limiting plate fixed above the guide column can limit and guide the first side plate. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A PET film testing device includes a tensile testing body 1. An installation mechanism 2 is installed on the top of the tensile testing body 1, and the bottom of the installation mechanism 2 is connected to one end of a pleated sleeve 3. The other end of the pleated sleeve 3 is connected to a drive frame 4. The drive frame 4 allows the pleated sleeve 3 to be easily unfolded to cover and protect the tensile testing body 1. Guide mechanisms 5 are fixedly connected to both sides of the drive frame 4, and the guide mechanisms 5 are inserted into a second side plate 6. The guide mechanisms 5 move along the second side plate 6 to limit and guide the drive frame 4. A limit mechanism 7 is fixedly connected to the side of the second side plate 6.

[0018] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the installation mechanism 2 includes mounting bolts 21. A connecting plate 22 is installed on the top of the tensile testing machine body 1 by mounting bolts 21, and a fixing plate 23 is fixedly connected to the top of the connecting plate 22. The mounting bolts 21 pass through the connecting plate 22 and are threadedly connected to the top of the tensile testing machine body 1, which facilitates the installation and removal of the fixing plate 23.

[0019] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the guiding mechanism 5 includes a first side plate 51, and the first side plate 51 is fixedly connected to both sides of the driving frame 4. A guide post 52 is fixedly connected to the top of the first side plate 51. Through the first side plate 51 fixedly connected to both sides of the driving frame 4, the first side plate 51 can easily drive the guide post 52 to move, which facilitates the function of limiting and guiding the driving frame 4.

[0020] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the guide post 52 is cylindrical, and the second side plate 6 has a round hole that matches the guide post 52. Through the round hole in the second side plate 6, the guide post 52 can move along the round hole, which plays the role of limiting and guiding the frame 4.

[0021] Furthermore, refer to Figure 2 and Figure 3It can be seen that a limiting plate 53 is fixedly connected above the guide post 52. The surface size of the guide post 52 is smaller than the surface size of the limiting plate 53. The limiting plate 53 can limit the guide post 52.

[0022] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the limiting mechanism 7 includes a fixed frame 71. The fixed frame 71 is fixedly connected to the outer side of the second side plate 6, and a push stud 72 is threaded into the outer end of the fixed frame 71. The end of the push stud 72 is connected to one side of the push plate 73 through a bearing, and a pressing column 74 is fixedly connected to the other side of the push plate 73. By rotating the push stud 72, the push plate 73 can be easily pushed, and the push plate 73 can easily control the pressing column 74.

[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the outer side of the second side plate 6 is provided with a round hole that matches the extrusion column 74. Through the round hole on the outer side of the second side plate 6, the extrusion column 74 can pass through the round hole and be extruded with the guide column 52, which facilitates the function of limiting the guide column 52. The end surface of the extrusion column 74 is glued with an anti-slip rubber head 75, and the surface of the anti-slip rubber head 75 is provided with anti-slip texture. Through the anti-slip rubber head 75 glued to the end surface of the extrusion column 74, the friction of the end of the extrusion column 74 can be increased, thereby improving the stability of the extrusion limiting guide column 52.

[0024] Working principle: When the tensile testing machine 1 is not in use, this utility model, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 By rotating the push stud 72, the push plate 73 can cause the extrusion column 74 to retract into the fixed frame 71. At this time, pulling the drive frame 4 can cause the first side plate 51 to drive the guide column 52 to slide along the second side plate 6, which facilitates the unfolding of the pleated sleeve 3. Thus, the pleated sleeve 3 can cover and shield the surface of the tensile test machine body 1. After the pleated sleeve 3 is unfolded, rotating the push stud 72 can easily push the push plate 73 and the extrusion column 74, which facilitates the extrusion column 74 to drive the anti-slip rubber head 75 to press against the surface of the guide column 52, thus limiting the drive frame 4. The above is the complete working principle of this utility model.
