Description

Technical Field

[0001] The utility model belongs to the technical field of easy-tear paper processing, and particularly relates to an easy-tear paper pasting rolling device. Background Art

[0002] Easy-tear paper consists of a protective film, an adhesive and a base paper layer stacked in sequence. When in use, the protective film can be torn off and the easy-tear paper can be adhered to the surface of the object to decorate and protect the object. When making easy-tear paper, the protective film needs to be covered on the surface of the base paper layer coated with the adhesive first, and then the two are pressed together.

[0003] Chinese patent publication number CN214872796U discloses a roller pressing mechanism for a back-adhesive laminating device, comprising a gantry and a first pressing roller. A second pressing roller is rotatably connected to the inner wall of the gantry. Two sets of first connecting plates are fixedly connected to the surface of the gantry. The surfaces of the first connecting plates are provided with a width adjustment mechanism, which includes a limit rod, an adjustment seat, and a threaded rod. The above scheme utilizes the rotation of the threaded rod, causing the threaded rod to drive the adjustment seat to move synchronously along the outer wall of the threaded rod and the limit rod, thereby adjusting the distance between the two sets of adjustment seats. This can limit the position of the back-adhesive and the product, preventing the back-adhesive and the product from shifting horizontally during lamination, which could lead to misalignment.

[0004] The above scheme can be used to press easy-tear paper after adjustment, but when using the above scheme, it is necessary to rotate the threaded rods of the two sets of width adjustment mechanisms separately, the operation is relatively complicated, and the value of the distance between the two adjustment seats changed by a single rotation of the threaded rod is small, resulting in low efficiency in adjusting the distance between the two adjustment seats. Utility Model Content

[0005] The utility model aims to provide a rolling device for pasting easy-tear paper, so as to solve the problem of low working efficiency existing in the above-mentioned solution.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] The lifting mechanism is connected with the lifting mechanism, and the lifting mechanism is connected with the lifting mechanism of the lifting mechanism, and the lifting mechanism is connected with the lifting mechanism of the lifting mechanism is connected with the lifting mechanism of the lifting mechanism.

[0008] The principle and effect of this technical solution:

[0009] After the protective film and the substrate paper layer are laminated together, they pass through the gap between the first roller and the second roller, and the height of the second roller is adjusted by using the lifting mechanism, and then the gap between the first roller and the second roller is adjusted so that the first roller and the second roller press the protective film and the substrate paper layer together. Subsequently, the locking mechanism is released, and the bidirectional screw is rotated. The two adjustment seats approach each other as the bidirectional screw rotates until the two adjustment seats respectively abut against the two sides of the protective film and the substrate paper layer. Finally, the locking mechanism is locked, and the end of the protective film and the substrate paper layer that are laminated is pulled to continuously press the protective film and the substrate paper layer together.

[0010] Through the above-mentioned setting, the height of the second roller is changed by setting a lifting mechanism, so that the first roller and the second roller can press protective films and substrate paper layers of different thicknesses, thereby broadening the applicable scenarios of the device. At the same time, by fitting the two adjustment seats on the forward and reverse thread sections of the bidirectional screw, the two adjustment seats can be moved at the same time, thereby improving the work efficiency of adjusting the distance between the two adjustment seats.

[0011] In the present invention, the lifting mechanism includes a rotating shaft and lifting components symmetrically arranged on both sides of the second roller. The lifting component includes a threaded rod that is vertically rotatable and inserted into the mounting frame, and a slider that is cooperatively sleeved on the threaded rod. The side wall of the slider is in sliding contact with the mounting frame. The two ends of the second roller are respectively rotatably inserted into the corresponding sliders. The rotating shaft is rotatably arranged at the top of the mounting frame and is respectively connected to the two threaded rods through transmission components.

[0012] In the present utility model, the transmission assembly includes a first bevel gear fixedly sleeved on the rotating shaft and a second bevel gear fixedly sleeved on the threaded rod, and the first bevel gear is meshed with the second bevel gear.

[0013] The principle and effect of this technical solution:

[0014] The rotating shaft is rotated, and the first bevel gear and the second bevel gear are engaged, thereby driving the two threaded rods to rotate. The side wall of the slider slides against the mounting bracket, and the mounting bracket restricts the slider from rotating with the threaded rod, and the slider moves up and down with the rotation of the threaded rod.

[0015] Through the above arrangement, the purpose of enabling the lifting mechanism to adjust the height of the second roller and then adjust the gap between the first roller and the second roller is achieved.

[0016] In the present utility model, one end of the rotating shaft is connected to the mounting bracket via a locking mechanism.

[0017] In the present utility model, the locking mechanism includes a prism, a sleeve, a tension spring and a limit block, wherein one end of the prism of the locking mechanism connected to the bidirectional screw is fixedly connected to one end of the bidirectional screw, and one end of the prism of the locking mechanism connected to the rotating shaft is fixedly connected to one end of the rotating shaft, one end of the sleeve is recessed with a slot that cooperates with the prism, and the other end of the prism is slidably inserted into the slot, the two ends of the tension spring connect the prism and the sleeve, the limit block is fixedly arranged on the outer side wall of the mounting frame, and the side wall at one end of the sleeve is recessed with multiple limit grooves that cooperate with the limit block along the circumferential direction.

[0018] The principle and effect of this technical solution:

[0019] When it is necessary to rotate the bidirectional screw or rotating shaft, pull the sleeve outward to disengage the limit block from the limit slot. At this time, the tension spring has elastic force. Rotate the sleeve in this state, and the other end of the prism slides and is inserted into the slot, thereby driving the bidirectional screw or rotating shaft to rotate; when it is necessary to limit the rotation of the bidirectional screw or rotating shaft, align the limit block with the corresponding limit slot, loosen the sleeve, and the tension spring pulls the sleeve close to the mounting bracket, and the limit block is stuck in the limit slot.

[0020] Through the above arrangement, the locking mechanism can limit the rotation of the bidirectional screw or the rotating shaft, thereby improving the stability of the device during use.

[0021] In the present invention, the sidewalls of the prism are provided with a groove along their length, and a protrusion is fixedly provided on the inner sidewall of the groove and is slidably embedded in the groove. This arrangement can prevent the sleeve from separating from the prism when the sleeve is pulled outward, thereby improving the practicality of the device.

[0022] In the present invention, a motor connected to the first roller is fixedly provided on the outer side wall of the mounting frame. Through the above arrangement, it is convenient for a worker to drive the first roller to rotate. BRIEF DESCRIPTION OF THE DRAWINGS

The lifting assembly 52 includes a threaded rod 521 that is vertically rotatable and inserted into the mounting frame 10, and a slider 522 that is cooperatively sleeved on the threaded rod 521. The side wall of the slider 522 slides and abuts against the mounting frame 10. The two ends of the second roller 32 are respectively rotatably inserted into the corresponding sliders 522. The rotating shaft 51 is rotatably set at the top of the mounting frame 10 and is respectively connected to the two threaded rods 521 through the transmission assembly 60.
