Description

Technical Field

[0001] The utility model belongs to the technical field of protective film production, and particularly relates to a limiting device for a protective film placement rack. Background Art

[0002] Protective film is a common surface protection material, often used to protect product surfaces from scratches, contamination, corrosion, and other damage. It can also enhance the surface and increase the product's value. Protective film has a wide range of applications, including electronics, automobiles, building materials, glass, and metal products.

[0003] The patent document with application number CN202120955787.2 proposes a placement rack for nano protective film production. Through the setting of the limit rod and the arc limit plate, the staff can install the winding roller with the nano protective film on the outside of the arc limit plate. At the same time, the rebound elasticity formed by the spring drives the arc limit plate to limit the winding roller and the nano protective film to prevent the nano protective film from falling. At the same time, the staff starts the forward and reverse motors, and drives the support rods and the limit rods to rotate through the forward and reverse motors, thereby adjusting the position of the arc limit plate, making it convenient for the staff to place the nano protective film in different positions.

[0004] The protective film placement rack proposed in the above document relies on clamping to fix the protective film. When placing or removing the protective film, the curved plate needs to be adjusted by motors and other components. The steps are relatively complicated, and the protective film is clamped in the middle. It also needs to rely on the motor to drive the limit rod and other components to be removed. When multiple sets of protective films are stored together, the protective film reels will be squeezed against each other due to contact with the side walls, resulting in scratches, and are also easy to loosen from the middle of the curved edge.

[0032] The mounting assembly 100 includes a fixing plate 101, a bracket 102 mounted on the upper end of the fixing plate 101, a main roller 103 mounted in the middle of the end of the bracket 102, and a secondary roller 104 mounted on the side wall of the end of the bracket 102. The secondary roller 104 is symmetrically arranged on the side wall of the end of the main roller 103 and is inclined relative to the side wall of the main roller 103.

[0033] The limiting assembly 200 includes a support plate 201, a support rod 202 installed at the end of the support plate 201, and a baffle 203 installed at the end of the support rod 202. The support plate 201 is installed in the middle of the fixed plate 101, and the end of the baffle 203 extends to the outside of the fixed plate 101.

[0034] Among them, the installation component 100 is used to store the protective film reel, and the bracket 102 is installed on the fixed plate 101 to cooperate with the installation of the main roller 103. The main roller 103 is used to assist the movement of the protective film reel and facilitate the removal of the protective film from the middle of the main roller 103. The main roller 103 replaces the protective film in contact with the fixed plate 101, which can reduce the friction generated when the protective film reel moves and maintain the safe storage of the protective film. An inclined auxiliary roller 104 is added to the side wall of the bracket 102. The auxiliary roller 104 is used to further cooperate with the movement of the protective film and can also move the protective film reel stored in the middle of the main roller 103 to a certain extent. The protective film can be limited to prevent it from falling, so that the protective film can be stored on the placement rack conveniently. A limiting component 200 is added in the middle of the fixed plate 101 to further cooperate with the placement rack to limit the protective film reel. The baffle 203 can prevent the protective film from falling from the outside of the main roller 103. By raising the support plate 201, the protective film reel can be raised from the middle of the main roller 103, which is convenient for moving the protective film downward along the support plate 201. The support rod 202 is used to extend the length of the support plate 201, which is convenient for guiding the protective film to the specified position. The baffle 203 can cooperate with the support rod 202 to limit the protective film to prevent it from falling.

[0035] Specifically, a connecting piece 105 is rotatably mounted on one side of the upper end of the bracket 102 , and the end of the secondary roller shaft 104 is mounted in the middle of the connecting piece 105 through a bearing.

[0036] A rotatable connector 105 is added in the middle of the bracket 102. By rotating the connector 105, the tilt angle of the secondary roller shaft 104 can be adjusted, so as to facilitate the docking, transmission and position limiting use of protective films of different sizes.

[0037] Furthermore, a support member 106 is installed at the other end of the secondary roller shaft 104 , and the support member 106 is connected to the side wall of the bracket 102 by bolts.

[0038] Among them, a support member 106 is installed at the other end of the secondary roller shaft 104 to connect with the bracket 102. After rotating to adjust the inclination angle of the secondary roller shaft 104, the support member 106 is fixed at the corresponding position of the side wall of the bracket 102, which can maintain the stability of the inclination angle of the secondary roller shaft 104 and prevent the secondary roller shaft 104 from loosening.

[0039] Furthermore, a guide post 204 is rotatably mounted on the bottom of the support plate 201 , and the guide post 204 is movably inserted into a through hole on the side wall of the fixing plate 101 .

[0040] Among them, a guide column 204 is installed at the bottom of the support plate 201. The guide column 204 can limit the moving position of the support plate 201, so that the support plate 201 can only move within the range of the guide column 204. The guide columns 204 on both sides of the bottom of the support plate 201 can be set to different lengths as needed. When the support plate 201 is fully raised, the end face of the support plate 201 will be tilted, which further facilitates the removal of the protective film.

[0041] Preferably, the lower end of the guide column 204 is connected to the spring 205 via a bolt, and the upper end of the spring 205 is fixedly connected to the bottom side wall of the fixing plate 101.

[0042] A spring 205 is installed at the lower end of the guide column 204 and docked with the fixed plate 101. The spring 205 can provide a downward elastic force to the guide column 204 based on the installation of the fixed plate 101, thereby further maintaining the stable movement of the support plate 201.

[0043] Preferably, a cylinder 206 is installed at the middle position of the bottom of the fixing plate 101, and the upper end of the cylinder 206 is connected to the middle position of the bottom of the supporting plate 201 through a pin.

[0044] Among them, a cylinder 206 is installed on the side wall of the fixed plate 101 to connect with the support plate 201. The cylinder 206 is driven by the control device to operate. The cylinder 206 can lift the support plate 201 on the side wall of the fixed plate 101, and then move the protective film to the top of the main roller 103, so as to facilitate the transfer of the protective film.

[0045] Preferably, a tension spring 207 is installed inside the support plate 201, and the end of the tension spring 207 is fixedly connected to the support rod 202 through a bolt.

[0046] Among them, a tension spring 207 is installed inside the support plate 201 to connect with the support rod 202. When the protective film moves to the side wall of the support plate 201, the support rod 202 will be pulled by the baffle 203 with the cooperation of the tension spring 207 and move toward the outside of the support plate 201. At this time, the tension spring 207 will be stretched, and the tension spring 207 cooperates with the support plate 201 to provide reverse tension to cushion the movement of the protective film and maintain smooth movement of the protective film.

[0047] Preferably, a handle bolt 208 is threadedly connected to the side wall of the support plate 201 , and an end of the handle bolt 208 passes through the support plate 201 and contacts the side wall of the support rod 202 .

[0048] Among them, the handle bolt 208 is installed on the side wall of the support plate 201 to connect with the support rod 202. Tightening the handle bolt 208 can fix the support rod 202 and maintain the stability of the position of the support rod 202, so that the baffle 203 can limit the protective film at a fixed position. Loosening the handle bolt 208 facilitates the adjustment of the baffle 203.

[0049] In summary, the mounting assembly 100 is used to store the protective film reel, and the bracket 102 is installed on the fixed plate 101 to cooperate with the installation of the main roller 103. The main roller 103 is used to assist the movement of the protective film reel and facilitate the removal of the protective film from the middle of the main roller 103. The main roller 103 replaces the protective film in contact with the fixed plate 101, which can reduce the friction generated when the protective film reel moves and maintain the safe storage of the protective film. An inclined auxiliary roller 104 is added to the side wall of the bracket 102. The auxiliary roller 104 is used to further cooperate with the movement of the protective film, and at the same time can move the protective film reel stored in the middle of the main roller 103 to a certain extent. The protective film can be limited to prevent it from falling, so that the protective film can be stored on the placement rack conveniently. A limiting component 200 is added in the middle of the fixed plate 101 to further cooperate with the placement rack to limit the protective film reel. The baffle 203 can prevent the protective film from falling from the outside of the main roller 103. By raising the support plate 201, the protective film reel can be raised from the middle of the main roller 103, which is convenient for moving the protective film downward along the support plate 201. The support rod 202 is used to extend the length of the support plate 201, which is convenient for guiding the protective film to the specified position. The baffle 203 can cooperate with the support rod 202 to limit the protective film to prevent it from falling.
