Description

Technical Field

[0001] This utility model relates to the field of heat shrinkable material production and processing technology, and in particular to a pressure roller adjuster. Background Technology

[0002] In the production and processing of heat-shrinkable materials, multiple cooperating rollers are typically used to guide and convey the sheets of heat-shrinkable material, and a gluing mechanism is used to press the sheets together. However, in existing technologies, the gaps between the rollers are fixed, making it inconvenient to adjust the conveying and pressing gaps.

[0003] Therefore, there is an urgent need to develop a pressure roller adjuster for production equipment (such as equipment involving residual glue thickness control, material pressing, etc.) that can conveniently adjust the longitudinal or lateral position of the roller, improve the ease of use and production compatibility of the equipment; by adjusting the spatial position of the pressure roller, it can ensure that the pressing accuracy, residual glue thickness and other process parameters meet the requirements in production, and provide support for stable production. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art and provides a pressure roller adjuster that can adjust the spatial position of the pressure roller, ensuring the ease of use and production compatibility of the lifting equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pressure roller adjuster, comprising: spaced-apart bases, with rotating rollers rotatably connected between the spaced-apart bases; bearing seats are respectively provided on the bases, and roller shafts extending to both ends of the rotating rollers are respectively rotatably limited in the bearing seats by bearings; telescopic connecting ends are provided on the outer periphery of the bearing seats; a drive seat is also provided at one end of each base, and a linear transmission mechanism is provided in each drive seat that is connected to the telescopic connecting end, and the synchronous shafts of the two linear transmission mechanisms are synchronously linked by a coupling.

[0006] In a preferred embodiment of this utility model, the linear transmission mechanism includes a synchronous shaft rotatably connected to a drive seat. One end of the synchronous shaft is connected to a handwheel, and the other end of the synchronous shaft passes through a transmission gear inside the drive seat and then exits the drive seat to connect with the coupling. One end of a drive guide rod movably inserted in the drive seat is connected to the outer telescopic connection end of the bearing seat, and the other end of the drive guide rod exits the linear transmission mechanism. The drive guide rod is provided with tooth grooves that mesh with the tooth surface of the transmission gear. The rotation of the transmission gear drives the drive guide rod to extend, thereby causing the bearing seat to telescopically displace relative to the base and the drive seat.

[0007] In a preferred embodiment of this utility model, a guide slider is provided on the outer periphery of the bearing housing; the guide slider is slidably limited in the telescopic groove of the base.

[0008] In a preferred embodiment of the present invention, each base is provided with an installation frame, and the installation frame is provided with a horizontally opened installation cavity for accommodating the bearing seat. The installation cavity of the installation frame is provided with a telescopic groove, and the guide slider is slidably limited in the telescopic groove of the base.

[0009] In a preferred embodiment of this utility model, the mounting frame is longitudinally fixed to the base by a locking screw; A lifting slide is provided on one side of the mounting frame. One end of the lifting connecting block moves through the lifting slide and is connected to the drive guide rod. The other end of the lifting connecting block is provided with a bracket 9 clamped on both sides of the telescopic connecting end. A limit groove is provided on the telescopic connecting end. The bracket is limited by the limit shaft 9 passing through the limit groove.

[0010] In a preferred embodiment of this utility model, a connector is also screwed onto the bracket and fixed to the telescopic connecting end. Tightening the connector is used to lock the relative position between the bracket and the telescopic connecting end.

[0011] In a preferred embodiment of this utility model, the opening trajectory of the limiting groove corresponds to the opening trajectory of the lifting slide.

[0012] In a preferred embodiment of this utility model, several pads are provided between the locking screw and the base. The pads have a groove-shaped structure, which facilitates insertion between the mounting frame and the base. The tightness of the locking screw is used to adjust the distance between the mounting frame and the base.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model discloses a pressure roller adjuster that can adjust the spatial position of the pressure roller, ensuring the ease of use and production compatibility of the lifting equipment.

[0014] 1. Manual adjustment enables dual-sided transmission, which drives the rotating roller to move relative to other rotating rollers, thereby adjusting the distance between the rotating rollers to meet production requirements.

[0015] 2. When the handwheel is turned on one side, the transmission gear rotates in the drive seat following the gear shaft. The tooth surface of the transmission gear meshes with the tooth groove on the drive guide rod, causing the drive guide rod to extend and retract relative to the drive seat, thereby adjusting the relative position of the bearing seat on the base.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features therein are detailed descriptions of the present invention, rather than limitations thereof. In the absence of conflict, the embodiments of the present invention and the technical features therein can be combined with each other.

[0019] The term "and / or" simply describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0020] Example 1, as Figures 1-4 As shown, a pressure roller adjuster includes: a pair of bases 4 spaced apart, each base 4 having a drive seat at one end, and a mounting frame 7 on each base 4. The mounting frame 7 is longitudinally fixed to the base 4 by a locking screw 34. The mounting frame 7 has a transversely opened mounting cavity for accommodating a bearing seat 3; roller shafts 11 extending to both ends of the roller 1 are rotatably fixed in the bearing seat 3 by bearings 2, that is, the spaced-apart bases 4 are rotatably connected to the roller 1, which can rotate relative to the base 4.

[0021] Specifically, the outer periphery of the bearing housing 3 is provided with a telescopic connecting end 31 and a guide slider 32; the mounting cavity of the mounting frame 7 is provided with a telescopic groove 71, and the guide slider 32 is slidably limited in the telescopic groove 71 of the base 4. Each drive seat is provided with a linear transmission mechanism 5 that is connected to the telescopic connecting end 31, and the synchronous shafts 6 of the two linear transmission mechanisms 5 are synchronously linked through a coupling 61.

[0022] Furthermore, the linear transmission mechanism 5 includes a synchronous shaft 6 rotatably connected to the drive seat. One end of the synchronous shaft 6 is connected to a handwheel 51, and the other end of the synchronous shaft 6 passes through a transmission gear 511 inside the drive seat and then exits the drive seat to connect with a coupling 61. The transmission gear 511 is provided with a tooth groove 521 that meshes with a rack on the telescopic connection end 31. The rotation of the transmission gear 511 drives the telescopic connection end 31 to drive the bearing seat 3 to telescopically move relative to the base 4 and the drive seat. One end of the drive guide rod 52, which is movably inserted into the guide groove of the drive seat, is connected to the outer telescopic connection end 31 of the bearing seat 3. The other end of the drive guide rod 52 exits the linear transmission mechanism 5, and the drive guide rod 52 is provided with a tooth groove 521 that meshes with the tooth surface of the transmission gear 511. The tooth grooves 521 are arranged on the rod body of the drive guide rod 52 to form a rack structure that can move linearly relative to the drive seat. The toothed grooves 521 on the drive guide rod 52 correspond to the transmission direction of the transmission gear 511 and the setting direction of the telescopic slide 71. The axes of the drive guide rod 52 and the synchronous shaft 6 are arranged in a cross pattern with an included angle of 90°. Furthermore, the drive guide rod 52 is also provided with a guide groove 522, and a guide block is provided inside the drive seat that is movably embedded in the guide groove 522 to improve the guiding performance of the telescopic displacement.

[0023] Working principle: This utility model discloses a pressure roller adjuster that can adjust the spatial position of the pressure roller, ensuring the ease of use and production compatibility of the lifting equipment. Manual adjustment enables dual-sided transmission, driving the rotating roller 1 to move relative to other rotating rollers, thus adjusting the distance between rotating roller 1 and other rotating rollers to meet production requirements. When the handwheel 51 is rotated on one side, driving the transmission gear 511 to rotate within the drive seat following the gear shaft, the tooth surface of the transmission gear 511 meshes with the tooth groove 521 on the drive guide rod 52, causing the drive guide rod 52 to extend and retract relative to the drive seat, thereby adjusting the relative position of the bearing seat 3 on the base 4. The structure of this embodiment allows for forward and backward displacement adjustment on either side, and adjusting one side enables synchronous driving of both ends of the rotating roller 1.

[0024] Example 2, as Figure 5 , Figure 6As shown, based on Embodiment 1, a lifting slide 33 is provided on one side of the mounting frame 7. One end of the lifting connecting block 9 moves through the lifting slide 33 and connects to the drive guide rod 52. The other end of the lifting connecting block 9 is provided with a bracket 91 clamped on both sides of the telescopic connecting end 31, and a limiting groove 311 is provided on the telescopic connecting end 31. The bracket 91 is limited by a limiting shaft 92 passing through the limiting groove 311. The opening trajectory of the limiting groove 311 corresponds to the opening trajectory of the lifting slide 33.

[0025] Specifically, the bracket 91 is also screwed with a connector 93 that is screwed and fixed to the telescopic connection end 31. Tightening the connector 93 is used to lock the relative position between the bracket 91 and the telescopic connection end 31.

[0026] Furthermore, several pads are provided between the locking screw 34 and the base 4. The pads have a groove-shaped structure, which facilitates insertion between the mounting frame 7 and the base 4. The tightness of the locking screw 34 is used to adjust the distance between the mounting frame 7 and the base 4.

[0027] Working principle: This utility model discloses a pressure roller adjuster that can adjust the spatial position of the pressure roller, ensuring the ease of use and production compatibility of the lifting equipment. Manual adjustment enables dual-sided transmission, driving the rotating roller 1 to shift relative to other rotating rollers, thus adjusting the distance between rotating roller 1 and other rotating rollers to meet production requirements. When the handwheel 51 is rotated on one side, driving the transmission gear 511 to rotate within the drive seat following the gear shaft, the tooth surface of the transmission gear 511 meshes with the tooth groove 521 on the drive guide rod 52, causing the drive guide rod 52 to extend and retract relative to the drive seat, thereby adjusting the front-to-back relative position of the bearing seat 3 on the base 4.

[0028] The rotating roller 1 is supported by a jack. Then, the locking screws 34 between the two bases 4 and the mounting frame 7 are loosened, thus releasing the fixed connection between the mounting frame 7 and the base 4. The jack is then used to lift the rotating roller 1. A shim is inserted between the mounting frame 7 and the base 4, and the mounting height of the rotating roller 1 on the base 4 is adjusted using the shim. Finally, the locking screws 34 between the two bases 4 and the mounting frame 7 are tightened, thus fixing the mounting frame 7 to the base 4. This adjusts the longitudinal relative position of the bearing seat 3 on the base 4.

The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the claims.
