Description

Technical Field

[0001] The utility model relates to the technical field of film collection equipment, in particular to a wrapping film follower film collection mechanism. Background Art

[0002] During transportation, the lids of cans are generally arranged one by one in long strips, then wrapped with film to form cylindrical strips. The packaged strips are then stacked on pallets in sequence, and a long stretch film (also called a restraint tape) is wrapped around each layer of material to prevent the layers of material from loosening. After stacking multiple layers, material chops are formed. During processing, the top layer of material strip is pushed out a small distance through a pushing mechanism, and then the material strip is clamped by a clamping mechanism and pulled out to the conveyor belt.

[0003] While people are loading the material strips, they also need to recycle the restraint belt. Since the material chops have a certain width, when reclaiming the restraint belt, it is necessary to follow the upward lifting direction of the restraint belt to guide it so that the restraint belt can be reclaimed as far as possible in the vertical direction to improve the recycling effect. However, the traditional recycling method generally rewinds the restraint belt directly above the material chops, which can easily cause excessive pulling of the restraint belt and lead to uneven rewinding. In this context, the applicant is committed to developing a wrap film follow-up film rewinding mechanism, which can achieve follow-up guidance of the restraint belt when reclaiming it, so that the restraint belt can be reclaimed as far as possible in the vertical direction to improve the recycling effect. Utility Model Content

[0004] The purpose of the utility model is to realize follow-up guidance of the restraining belt when the restraining belt is recovered, so that the restraining belt is recovered upward along the vertical direction as much as possible, thereby improving the recovery effect.

[0005] In order to achieve the above purpose, the technical solutions adopted by the present invention are as follows:

[0006] A stretch film follow-up film-winding mechanism comprises a controller, a transverse movement mechanism, a movable frame, and two sets of symmetrically arranged follow-up control mechanisms, wherein the controller controls the transverse movement mechanism to drive the movable frame to move back and forth;

[0007] The servo control mechanism includes a proximity sensor, a hinge, and a rotating block. The rotating block is hinged to the mobile frame through the hinge. The proximity sensor is electrically connected to the controller and is located on a side of the rotating block away from the other set of servo control mechanisms.

[0008] Furthermore, a guide plate is fixedly provided at the lower end of the movable frame.

[0009] Furthermore, a guide die groove is provided on the guide die plate.

[0010] Furthermore, the rotating blocks of the two sets of follow-up control mechanisms are respectively located on two side edges of the guide die groove.

[0011] Furthermore, a section of the rotating block close to another set of follow-up control mechanisms is provided with a chamfered structure.

[0012] Furthermore, the transverse movement mechanism includes a first driving mechanism, a synchronous belt assembly, a linear rail and a slider. The first driving mechanism drives the synchronous belt assembly to work, and the synchronous belt assembly drives the slider to slide back and forth along the linear rail. The movable frame is fixedly connected to the slider.

[0013] Furthermore, it also includes two groups of clamping mechanisms, the clamping mechanism includes a second driving mechanism and a clamping block, the second driving mechanism is fixedly arranged on the movable frame, and the second driving mechanism drives the clamping block to move back and forth toward the direction of the other group of clamping mechanisms.

[0014] Furthermore, it also includes a transition roller, which is pivotally connected to the movable frame.

[0015] The beneficial effect of the utility model is that when the restraining belt is recovered, the restraining belt is passed between the rotating blocks of the two groups of follow-up control mechanisms and is wound around other external winding equipment.

[0016] When the lower restraint belt is located on the left side, the restraint belt will pass between the two rotating blocks at a certain angle. At the same time, the restraint belt will be close to the rotating block on the left, and when the restraint belt rises, one end of the rotating block on the left will be driven upward, so that the rotating block will rotate around the hinge at a certain angle. At this time, the proximity sensor on the left senses the position change of the rotating block on the left and gives a signal to the controller. The controller controls the transverse movement mechanism to drive the mobile frame to move to the left until the rising restraint belt is in a vertical state. The rotating block on the left droops under the action of its own gravity. At this time, the proximity sensor cannot sense the position change of the rotating block on the left, and the controller controls the transverse movement mechanism to stop driving the mobile frame to move left.

[0017] Conversely, when the lower restraint belt is on the right side, the restraint belt will drive the right rotating block to rotate around the hinge at a certain angle. At this time, the proximity sensor on the right senses the position change of the rotating block and sends a signal to the controller. The controller controls the transverse movement mechanism to drive the mobile frame to move to the right until the raised restraint belt is in a vertical state. The right rotating block droops under the action of its own gravity. At this time, the proximity sensor cannot sense the position change of the right rotating block. The controller controls the transverse movement mechanism to stop driving the mobile frame to move right, thereby realizing the mobile frame to follow-up guide the restraint belt, so that the restraint belt is recovered upward along the vertical direction as much as possible, making the winding more neat and further improving the recovery effect.

[0027] The present invention will be further described below with reference to the accompanying drawings. It should be noted that the directional words such as up, down, left, right, front, and back described in this embodiment are all represented by Figure 1 The directions shown in the table shall prevail.

[0028] like Figures 1 to 3 The stretch film follow-up film-winding mechanism shown includes a controller, a transverse movement mechanism 1, a movable frame 2, two sets of follow-up control mechanisms 3, two sets of clamping mechanisms 4, and a transition roller 5.

[0029] The two sets of follow-up control mechanisms 3 are symmetrically arranged with each other, and the controller controls the transverse movement mechanism 1 to drive the movable frame 2 to move back and forth horizontally.

[0030] The transverse movement mechanism 1 includes a first driving mechanism 11, a synchronous belt assembly, a linear rail 12 and a slider 13. The first driving mechanism 11 drives the synchronous belt assembly to work, and the synchronous belt assembly drives the slider 13 to slide back and forth along the linear rail 12. The movable frame 2 is fixedly connected to the slider 13. When the slider 13 slides back and forth on the linear rail 12, it drives the movable frame 2 to move back and forth.

[0031] The follow-up control mechanism 3 includes a proximity sensor 31, a hinge 32, and a rotating block 33. The rotating block 33 is hinged to the mobile frame 2 through the hinge 32. The proximity sensor 31 is electrically connected to the controller, and the proximity sensor 31 is located on the side of the rotating block 33 away from the other set of follow-up control mechanisms 3. The hinge 32 is set at one end of the rotating block 33 away from the other set of follow-up control mechanisms 3. When the rotating block 33 on the same side rotates around the hinge 32, the proximity sensor 31 can detect the position change of the rotating block 33 and then give a signal to the controller.

[0032] A guide plate 21 is fixedly provided at the lower end of the movable frame 2, and a guide plate groove 211 is opened on the guide plate 21. The rotating blocks 33 of the two sets of follow-up control mechanisms 3 are respectively located on both sides of the guide plate groove 211; the restraint belt 6 to be recovered passes through the guide plate groove 211, and the restraint belt 6 passes between the two rotating blocks 33.

[0033] A section of the rotating block 33 close to the other set of follow-up control mechanisms 3 is provided with a chamfered structure, so as to facilitate the mutual cooperation with the restraint belt 6 .

[0034] The clamping mechanism 4 includes a second driving mechanism 41 and a clamping block 42. The second driving mechanism 41 is fixedly arranged on the movable frame 2. The second driving mechanism 41 drives the clamping block 42 to move back and forth toward another group of clamping mechanisms 4. The function of the clamping mechanism 4 is that when the material strip is pushed out, the second driving mechanism 41 drives the clamping block 42 to be pushed out toward another group of clamping mechanisms 4. The restraint belt 6 is clamped by the two clamping blocks 42 to prevent the restraint belt 6 from sliding with the material strip.

[0035] The transition roller 5 is pivotally connected to the movable frame 2 , and the transition roller 5 plays a transition role in the recovery of the restraint belt 6 .

[0036] Working principle: When retrieving the restraint belt 6, the restraint belt 6 is passed between the rotating blocks 33 of the two sets of follow-up control mechanisms 3 and wrapped around other external winding equipment. When the lower restraint belt 6 is on the left side, the restraint belt 6 will pass between the two rotating blocks 33 at a certain angle. At the same time, the restraint belt 6 will be close to the rotating block 33 on the left, and when the restraint belt 6 rises, one end of the rotating block 33 on the left is driven upward, and the angle of the membrane relative to the vertical direction changes, causing the rotating block 33 to rotate a certain angle around the hinge 32. At this time, the proximity sensor 31 on the left senses the position change of the left rotating block 33 and gives a signal to the controller. The controller controls the transverse mechanism 1 to drive the movable frame 2 to move to the left until the rising restraint belt 6 is in a vertical state. The left rotating block 33 droops under the action of its own gravity. At this time, the proximity sensor 31 cannot sense the position change of the left rotating block 33, and the controller controls the transverse mechanism 1 to stop driving the movable frame 2 to move left.

[0037] Conversely, when the lower constraint belt 6 is located on the right side, the angle of the membrane relative to the vertical direction changes. When the constraint belt 6 rises, it will drive the rotating block 33 on the right to rotate a certain angle around the hinge 32. At this time, the proximity sensor 31 on the right senses the position change of the rotating block 33 and sends a signal to the controller. The controller controls the transverse movement mechanism 1 to drive the mobile frame 2 to move to the right until the rising constraint belt 6 is in a vertical state. The right rotating block 33 droops under the action of its own gravity. At this time, the proximity sensor 31 cannot sense the position change of the right rotating block 33. The controller controls the transverse movement mechanism 1 to stop driving the mobile frame 2 to move right, thereby realizing that the mobile frame 2 guides the constraint belt 6, so that the constraint belt 6 is recovered upward along the vertical direction as much as possible, making the winding more neat and further improving the recycling effect.
