Description

Technical Field

[0001] The utility model relates to the technical field of plastic film winding devices, in particular to a plastic film winding roller. Background Art

[0002] In the production process of plastic film, the plastic film after calendering needs to be wound up by a winding mechanism. The conventional winding method is to first manually stick one end of the plastic film to the roller core of the winding roller with tape, and then wind it up. If this method is used in a continuous production line, the plastic film may not need to be removed from the winding roller, but can be directly processed or handled in the next step. However, if the wound plastic film needs to be stored, transported or processed later, it is usually necessary to remove the plastic film from the winding roller. Since one end of the plastic film is previously stuck to the roller core of the winding roller with tape, it is more difficult to remove the plastic film from the winding roller. Utility Model Content

[0003] The utility model provides a plastic film winding roller, which can overcome certain defects of the prior art.

[0004] According to the utility model, a plastic film winding roller comprises: a winding roller main body, the winding roller main body comprises a roller core; both ends of the roller core are hingedly provided with baffle rods, the baffle rods and the roller core together constitute a limiting interval for limiting the plastic film; the bottom of the limiting interval is provided in a limiting groove arranged along the length direction of the roller core and for one end of the plastic film to extend into; an extrusion piece is provided in the limiting groove, and the extrusion piece is used to cooperate with the baffle rod to limit one end of the plastic film in the limiting groove.

[0005] According to the utility model, the roller core is connected to the motor through the connecting end. The staff first inserts one end of the plastic film into the limiting groove, and then rotates the stop lever to insert the extrusion block on the stop lever into the extrusion interval. After the extrusion block is inserted into the extrusion interval, the extrusion block pushes the extrusion plate, and the extrusion plate presses one end of the plastic film against the inner wall of the limiting groove; thereby facilitating the staff to connect one end of the plastic film to the roller core; then the staff starts the motor, and the motor drives the roller core to rotate, thereby rewinding the plastic film; after the plastic film is rewound, the staff only needs to move the stop lever to disengage the extrusion block on the stop lever from the extrusion interval. After the extrusion block disengages the extrusion interval, the first rubber pad pulls the extrusion plate away from one end of the plastic film, thereby releasing the fixation on one end of the plastic film, and simultaneously rotating the stop lever along the hinge also opens the limiting interval. At this time, the staff only needs to rotate the plastic film roll, pull the end of the plastic film inserted into the limiting groove out of the limiting groove, and then pull the plastic film roll to remove the plastic film roll from one side of the roller core; thereby facilitating the staff to remove the plastic film roll from the roller core.

[0006] Preferably, the extrusion member includes an extrusion plate arranged along the length direction of the limiting groove, and a first rubber pad is provided between the extrusion plate and the inner side wall of the limiting groove, and the length of the first rubber pad is less than the length of the extrusion plate; the first rubber pad, the extrusion plate and the limiting groove together constitute an extrusion interval; an extrusion block extending into the extrusion interval is provided at the side wall of the baffle rod, and a first inclined surface matching the extrusion plate is provided at the extrusion block; the extrusion block is used to extend into the extrusion interval and push the extrusion plate close to the inner side wall of the limiting groove.

[0007] According to the utility model, after the extrusion block extends into the extrusion interval, the extrusion block pushes the extrusion plate to move, and at this time the extrusion plate pulls the first rubber pad, causing the first rubber pad to deform; after the extrusion block leaves the extrusion interval, the first rubber pad pulls the extrusion plate to return to its original position, so that the extrusion plate can complete the fixation of one end of the plastic film according to the extension and exit of the extrusion block into and out of the extrusion interval;

[0008] When the extrusion block extends into the extrusion interval, the first inclined surface on the extrusion block will abut against the extrusion plate, and one end of the extrusion plate will slide along the first inclined surface, thereby facilitating the smooth insertion of the extrusion block into the extrusion interval.

[0009] Preferably, a first rough surface is provided at one end surface of the extrusion plate close to the extrusion block, and a second rough surface matching the first rough surface is provided at the extrusion block.

[0010] Through the utility model, after the extrusion block extends into the extrusion interval, the first rough surface on the extrusion plate contacts the second rough surface on the extrusion block, thereby increasing the friction between the extrusion block and the extrusion plate, preventing the extrusion block on the baffle rod from escaping from the extrusion interval when the roller core rotates, causing one end of the plastic film to detach from the extrusion plate.

[0011] Preferably, a second inclined surface is provided at one end of the blocking rod away from the hinge.

[0012] Through the utility model, during the winding process of the plastic film, the plastic film first enters the limit interval from above the baffle bar. During the process of entering the limit interval, the plastic film will slide into the limit interval along the second inclined surface. The second inclined surface is provided above the baffle bar, thereby expanding the opening above the limit interval, thereby preventing the plastic film from pressing against the baffle bar and being unable to enter the limit interval when winding the plastic film.

[0013] Preferably, a second rubber pad is provided at an end surface of the extrusion plate away from the first rubber pad.

[0014] With the utility model, the second rubber pad on the extrusion plate contacts the plastic film at one end extending into the limiting groove, thereby increasing the friction between the extrusion plate and the plastic film, preventing the plastic film from separating from the extrusion plate; at the same time, the second rubber pad is easily deformed, preventing the extrusion plate from crushing the plastic film when extruding the plastic film.

[0015] Preferably, the barrier rod is made of stainless steel.

[0016] The utility model has a stainless steel structure with high strength, which increases the service life of the barrier rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to further understand the content of the present invention, the present invention is described in detail with reference to the embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention. Example

[0024] like Figure 1-6 As shown, in this embodiment, a plastic film winding roller is provided, including a winding roller body 100, and the winding roller body 100 includes a roller core 120; both ends of the roller core 120 are hingedly provided with a baffle 110, and the baffle 110 and the roller core 120 together constitute a limiting interval 140 for limiting the plastic film; the bottom of the limiting interval 140 is provided along the length direction of the roller core 120, and a limiting groove 210 is provided for one end of the plastic film to extend into; an extrusion piece 220 is provided in the limiting groove 210, and the extrusion piece 220 is used to cooperate with the baffle 110 to limit one end of the plastic film in the limiting groove 210.

[0025] Through this embodiment, the roller core 120 is connected to the motor through the connecting end 130. The staff first inserts one end of the plastic film into the limiting groove 210, and then rotates the baffle 110 to insert the extrusion block 510 on the baffle 110 into the extrusion interval 420. After the extrusion block 510 is inserted into the extrusion interval 420, the extrusion block 510 will push the extrusion plate 310, and the extrusion plate 310 will press one end of the plastic film against the inner wall of the limiting groove 210; thereby making it convenient for the staff to connect one end of the plastic film to the roller core 120; then the staff The staff starts the motor, which drives the roller core 120 to rotate, thereby rolling up the plastic film. After the plastic film is rolled up, the staff only needs to move the blocking rod 110 to disengage the squeezing block 510 on the blocking rod 110 from the squeezing section 420. After the squeezing block 510 disengages the squeezing section 420, the first rubber pad 320 pulls the squeezing plate 310 away from one end of the plastic film, thereby releasing the fixation on one end of the plastic film. At the same time, the blocking rod 110 rotates along the hinge to open the limit section 140. At this time, the staff only needs to rotate the plastic film roll. The end of the plastic film that extends into the limit groove 210 is pulled out of the limit groove 210, and then the plastic film roll is pulled out from one side of the roller core 120. This makes it convenient for the staff to remove the plastic film roll from the roller core 120.

[0026] In this embodiment, the extrusion member 220 includes an extrusion plate 310 arranged along the length direction of the limiting groove 210, and a first rubber pad 320 is provided between the extrusion plate 310 and the inner wall of the limiting groove 210, and the length of the first rubber pad 320 is less than the length of the extrusion plate 310; the first rubber pad 320, the extrusion plate 310 and the limiting groove 210 together constitute an extrusion interval 420; an extrusion block 510 extending into the extrusion interval 420 is provided at the side wall of the blocking rod 110, and a first inclined surface 520 cooperating with the extrusion plate 310 is provided at the extrusion block 510; the extrusion block 510 is used to extend into the extrusion interval 420 and push the extrusion plate 310 close to the inner wall of the limiting groove 210.

[0027] According to this embodiment, after the extrusion block 510 extends into the extrusion interval 420, the extrusion block 510 pushes the extrusion plate 310 to move. At this time, the extrusion plate 310 pulls the first rubber pad 320, causing the first rubber pad 320 to deform. After the extrusion block 510 leaves the extrusion interval 420, the first rubber pad 320 pulls the extrusion plate 310 to return to its original position, so that the extrusion plate 310 can complete the fixation of one end of the plastic film according to the extension and withdrawal of the extrusion block 510 into and out of the extrusion interval 420.

[0028] When the extrusion block 510 extends into the extrusion interval 420 , the first inclined surface 520 on the extrusion block 510 will abut against the extrusion plate 310 , and one end of the extrusion plate 310 will slide along the first inclined surface 520 , thereby facilitating the smooth insertion of the extrusion block 510 into the extrusion interval 420 .

[0029] In this embodiment, a first rough surface 410 is provided at one end surface of the extrusion plate 310 close to the extrusion block 510 , and a second rough surface 530 matching the first rough surface 410 is provided at the extrusion block 510 .

[0030] Through this embodiment, after the extrusion block 510 extends into the extrusion interval 420, the first rough surface 410 on the extrusion plate 310 contacts the second rough surface 530 on the extrusion block 510, thereby increasing the friction between the extrusion block 510 and the extrusion plate 310, preventing the extrusion block 510 on the baffle 110 from separating from the extrusion interval 420 when the roller core 120 rotates, causing one end of the plastic film to separate from the extrusion plate 310.

[0031] In this embodiment, a second inclined surface 540 is provided at one end of the blocking lever 110 away from the hinge.

[0032] Through this embodiment, during the winding process of the plastic film, the plastic film first enters the limit interval 140 from above the baffle 110. In the process of entering the limit interval 140, the plastic film will be drawn into the limit interval 140 along the second inclined surface 540. The second inclined surface 540 is provided above the baffle 110, thereby expanding the opening above the limit interval 140, thereby preventing the plastic film from pressing against the baffle 110 and being unable to enter the limit interval 140 when winding the plastic film.

[0033] In this embodiment, a second rubber pad 610 is provided on an end surface of the extrusion plate 310 away from the first rubber pad 320 .

[0034] Through this embodiment, the second rubber pad 610 on the extrusion plate 310 contacts the plastic film at one end extending into the limiting groove 210, thereby increasing the friction between the extrusion plate 310 and the plastic film, preventing the plastic film from separating from the extrusion plate 310; at the same time, the second rubber pad 610 is easily deformed, preventing the extrusion plate 310 from crushing the plastic film when squeezing the plastic film.
