Abstract
Description
Technical Field
[0001] This utility model relates to the field of new materials technology, and in particular to a die-cutting device for acrylic adhesive production. Background Technology
[0002] Acrylic tape is made of acrylic material as the base material and covered with release film or release paper. In the production and processing of acrylic tape, die-cutting equipment is needed to cut the finished product before packaging and sale. Therefore, a die-cutting equipment for acrylic tape production is particularly needed.
[0003] However, existing die-cutting equipment requires waiting for the mother roll to be replaced after cutting before it can continue cutting. This is time-consuming and labor-intensive, which seriously affects the efficiency of acrylic tape die-cutting. Some equipment can cut continuously and can rotate and install multiple mother rolls, but the mother rolls are fixed to the rotating frame with bolts, which is a relatively troublesome installation method. Therefore, this application discloses a die-cutting setup for acrylic tape production. Utility Model Content
[0004] The purpose of this invention is to address existing problems by providing a die-cutting setup for acrylic adhesive production.
[0005] This utility model is achieved through the following technical solution: a die-cutting device for acrylic adhesive production, including a main frame, one end of which is connected to an end frame, and a rotating frame is rotatably connected to the end frame via a bearing seat. A clamping mechanism is provided at the outer end of the frame rod of the rotating frame. Guide rails are spaced apart on the main frame near the end of the rotating frame, and sliders are matched on the guide rails. The outer end of the connecting plate of the correction mechanism is connected to the slider. A flat plate is provided on the rear side of the main frame, and a cutter of the cutting mechanism is rotatably provided on the top of the flat plate. The optical shaft end of the cutting mechanism is connected to a drive wheel, and the drive wheel is connected to a driven wheel via a belt. The driven wheel is sleeved on the end shaft of the drive roller, and the end shaft is connected to the rear end of the main frame via a roller frame.
[0006] The rotating frame includes a frame rod, the inner end of which is circumferentially connected to the inner end of an end shaft. The end shaft is mounted on the end frame through a bearing seat, and a support rod is connected between the end shafts.
[0007] Multiple master rolls are clamped by clamping mechanisms at the outer ends of multiple symmetrical support rods on the rotating frame. When a master roll has been completely unwound, the rotating frame rotates, and the master roll clamped on the next support rod continues to be unwound, realizing continuous unwinding for continuous die-cutting operations. Once one master roll is unwound, it can be clamped and installed.
[0008] As a further improvement to the above solution, the correction mechanism includes connecting plates, connecting sleeves between the connecting plates, an upper plate connected to the outer end of the connecting plates, a limiting wheel rotatably connected to the inner side of the vertical plate, a lead screw threaded into the sleeve, a rod seat connected to the inner end of the lead screw, the rod seat connected to the guide rails, a smooth rod rotatably sleeved into the rod frame at the outer end of the lead screw, the rod frame connected to the main frame, and a ring handle connected to the end of the smooth rod.
[0009] After the conveyor belt is moved to the correction mechanism, the conveyor belt is limited by the vertical plate and pressed by the limit wheel to prevent the conveyor belt from deviating or jumping and shaking during the displacement process. The screw rotates to move the screw sleeve, which drives the connecting plate, vertical plate and limit wheel to move on the guide rail at the same time with the slider, ensuring that the conveyor belt moves in the correct direction and avoiding the deviating of the conveyor belt.
[0010] As a further improvement to the above solution, the cutting mechanism includes a cutting blade, which is spaced and sleeved on the flower shaft. The end of the flower shaft is connected to the optical shaft, one end of the optical shaft is connected to a motor, and the optical shaft is rotatably connected to the bracket. The motor is installed on the outside of the bracket.
[0011] The motor drives the cutter to rotate via the swivel wheel to cut the tape into strips. In addition, the width of the cut strips can be adjusted by the displacement of the cutter on the swivel shaft, making it suitable for die-cutting tapes of different specifications.
[0012] As a further improvement to the above solution, the end of the cutter is connected to a fixing seat, and bolts are provided on the fixing seat;
[0013] The cutter is locked to the flower shaft by bolts to prevent the cutter from shifting during rotation.
[0014] As a further improvement to the above solution, the clamping mechanism includes a plug, the outer end of which is connected to one end of a baffle, the other end of which is connected to the inner end of a sliding column, the sliding column is slidably fitted onto the outer end of the frame rod, the outer end of the sliding column is connected to an end plate, the outer end of the end plate is connected to a pull ring, and a spring is fitted on the sliding column between the end plate and the frame rod.
[0015] Pulling the pull ring causes the sliding pin, baffle, and insert pin to move outward, increasing the distance between the insert pins to facilitate insertion into the inner hole of the mother roll. Releasing the pull ring causes the spring force to push the baffle to move, which in turn causes the sliding pin to move inward on the support rod, decreasing the distance between the two insert pins and clamping the mother roll through the baffle.
[0016] As a further improvement to the above solution, an angle plate is provided between the threaded sleeve and the connecting plate to strengthen the connection structure between the two, ensure the stability of the connecting plate, and prevent the connecting plate from falling off the threaded sleeve.
[0017] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. Multiple master rolls are clamped by a clamping mechanism installed on the rotating frame. The tape is led out and the vertical plate of the correction mechanism restricts the skew displacement. At the same time, the limit wheel presses against the tape to ensure the straightness of the tape displacement. Then, the tape is cut by the rotation of the cutter, so that each tape strip is straight and avoids skew. The rotation of the flower shaft drives the drive roller to rotate and pull the cut tape strips to the rear through the belt drive. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] like Figures 1 to 4 As shown, a die-cutting setup for acrylic adhesive production includes a main frame 1, with one end of the main frame 1 connected to an end frame 2. A rotating frame 3 is rotatably connected to the end frame 2 via a bearing seat. A clamping mechanism 4 is provided at the outer end of the frame rod 33 of the rotating frame 3. A guide rail 5 is spaced apart on one end of the main frame 1 near the rotating frame 3. A slider 6 is matched on the guide rail 5. The outer end of the connecting plate 71 of the correction mechanism 7 is connected to the slider 6. A flat plate 8 is provided on the rear side of the main frame 1. A cutter 9 of a cutting mechanism is rotatably provided on the top of the flat plate 8. The end of the optical shaft 94 of the cutting mechanism is connected to a drive wheel 11. The drive wheel 11 is connected to a driven wheel 13 via a belt 14. The belt 14 is wound into an "8" shape to change the direction of power transmission, ensuring that the drive roller 12 rotates and drives the tape to move backward. The driven wheel 13 is sleeved on the end shaft 31 of the drive roller 12. The end shaft 31 is connected to the rear end of the main frame 1 via a roller frame 15.
[0024] The rotating frame 3 includes a frame rod 33, the inner end of which is circumferentially connected to the inner end of the end shaft 31. The end shaft 31 is mounted on the end frame 2 through a bearing seat, and the end shafts 31 are connected by support rods 32.
[0025] Multiple master rolls are clamped by clamping mechanisms 4 at the outer ends of multiple symmetrical support rods 33 on the rotating frame 3. When a master roll has been completely unwound, the rotating frame 3 rotates, and the master roll clamped on the next support rod 33 continues to be unwound, realizing continuous unwinding for continuous die-cutting operations. Once one unwinding is completed, a master roll can be installed and clamped.
[0026] As a further improvement to the above solution, the correction mechanism 7 includes a connecting plate 71, a threaded sleeve 74 connecting the connecting plates 71, a vertical plate 72 connected to the upper part of the outer end of the connecting plate 71, a limiting wheel 73 rotatably connected to the inner side of the vertical plate 72, a threaded sleeve 74 threadedly connecting a lead screw 75, a rod seat 76 connected to the inner end of the lead screw 75, the rod seat 76 connected to the guide rail 5, a smooth rod at the outer end of the lead screw 75 rotatably sleeved in a rod frame 79, the rod frame 79 connected to the main frame 1, and a ring handle 78 connected to the end of the smooth rod.
[0027] After the tape is moved to the correction mechanism 7, the tape is limited by the vertical plate 72 and pressed by the limit wheel 73 to prevent the tape from deviating or jumping and shaking during the displacement process. The screw 75 rotates to move the screw sleeve 74, which in turn drives the connecting plate 71, the vertical plate 72, and the limit wheel 73 to move on the guide rail 5 along with the slider 6, ensuring that the tape moves in the correct direction and preventing the tape from deviating.
[0028] As a further improvement to the above solution, the cutting mechanism includes a cutter 9, which is spaced and sleeved on the flower shaft 93. The end of the flower shaft 93 is connected to the optical shaft 94, one end of the optical shaft 94 is connected to the motor 10, and the optical shaft 94 is rotatably connected to the bracket 95. The motor 10 is installed on the outside of the bracket 95.
[0029] The motor 10 drives the cutter 9 to rotate via the swivel wheel to cut the tape into strips. In addition, the cutter 9 can be moved on the swivel shaft 93 to adjust the width of the cut tape, which is suitable for die-cutting tapes of different specifications.
[0030] As a further improvement to the above solution, the end of the cutter 9 is connected to a fixing seat 91, and a bolt 92 is provided on the fixing seat 91;
[0031] The cutter 9 is locked on the flower shaft 93 by bolt 92 to prevent the cutter 9 from shifting during rotation.
[0032] As a further improvement to the above solution, the clamping mechanism 4 includes a pin 41, the outer end of which is connected to one end of a baffle 42, the other end of which is connected to the inner end of a sliding pin 43, the sliding pin 43 is slidably fitted onto the outer end of a support rod 33, the outer end of which is connected to an end plate 45, the outer end of which is connected to a pull ring 46, and a spring 44 is fitted onto the sliding pin 43 between the end plate 45 and the support rod 33.
[0033] Pulling the pull ring 46 causes the sliding pin 43, baffle 42, and insert pin 41 to move outward, increasing the distance between the insert pins 41 to facilitate insertion of the insert pins 41 into the inner hole of the mother roll. Releasing the pull ring 46 causes the force of the spring 44 to push the baffle 42 to move, which in turn causes the sliding pin 43 to move inward on the support rod 33, decreasing the distance between the two insert pins 41 and clamping the mother roll through the baffle 42.
[0034] As a further improvement to the above solution, an angle plate is provided between the threaded sleeve 74 and the connecting plate 71 to strengthen the connection structure between the two, ensure the stability of the connecting plate 71, and prevent the connecting plate 71 from falling off the threaded sleeve 74.
[0035] The working principle of a die-cutting device for acrylic adhesive production: Multiple master rolls are clamped by a clamping mechanism 4 installed on a rotating frame 3. The tape is led out and the vertical plate 72 of the correction mechanism 7 restricts the skew displacement. At the same time, the limit wheel 73 presses against the tape to ensure the straightness of the tape displacement. Then, the tape is cut by the rotation of the cutter 9, so that each tape strip is straight and avoids skew. The rotation of the patterned shaft 93 drives the drive roller 12 to rotate and pull the cut tape strips to the rear.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
