Description

Technical Field

[0001] This utility model belongs to the field of tape processing technology, and in particular relates to a slitting machine for tape processing. Background Technology

[0002] During the production of adhesive tape, an automatic slitting machine is needed to divide a large roll of adhesive tape into multiple smaller rolls. The winding structure is relatively fixed during production, which makes it inconvenient to adjust flexibly according to needs and can easily lead to the tape becoming loose during winding.

[0003] To address the aforementioned issues, the publication (announcement) number CN219429329U describes a method to ensure the tape remains taut by adjusting the position of the take-up sleeve, thus preventing loose winding during the slitting process. However, this method suffers from the following problem: the take-up sleeve is placed rather haphazardly, which can lead to uneven winding of the slitting tape during the winding process. Utility Model Content

[0004] The technical problem this invention aims to solve is that the placement of the winding sleeve is often arbitrary, which makes it easy for the slit tape to be unevenly wound during the winding process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a slitting machine for tape processing, comprising a frame and a top frame, wherein two sets of the frame are symmetrically distributed, and the top frame is fixedly connected to the top of the frame. The top frame is arranged in a U-shape. It also includes...

[0006] The feeding assembly, located on the frame, is used for feeding the tape.

[0007] The tensioning and slitting assembly is located on the top frame and the machine frame. It includes a pressure cylinder that moves vertically below the top frame, a rotating drum that is rotatably connected between the inner walls of the machine frame, and a slitting blade that is fixedly connected to the rotating drum. It is used for slitting the tape.

[0008] The winding assembly, mounted on a frame, includes a cylinder rotatably connected to the frame, a winding drum horizontally slidable on the cylinder, and a positioning mechanism located inside the cylinder, for winding the tape.

[0009] Furthermore, the tensioning slitting assembly includes an electric push rod, a connecting frame, and a rotary motor, wherein:

[0010] The electric push rod vertically penetrates the top frame and is fixedly connected to it, and its output end is located below the top frame and between the machine frame. The connecting frame is fixedly connected to the free end of the electric push rod and is arranged in a ∩ shape. The pressure cylinder is rotatably connected between the inner walls of the connecting frame. The rotary motor is fixedly installed on the machine frame, and its output end is fixedly connected to one end of the rotating cylinder. The slitting blades are symmetrically distributed on the rotating cylinder.

[0011] Furthermore, the positioning mechanism includes a servo motor, an adjusting rod, an adjusting block, a connecting plate, a connecting rod, and an insert block, wherein:

[0012] The servo motor is fixedly installed at the end of the cylinder. One end of the adjusting rod is fixedly connected to the output end of the servo motor, and the other end is rotatably connected to the inner wall of the cylinder. The adjusting rod is provided with multiple sets of bidirectional threads. The adjusting block is threadedly connected to the adjusting rod and is arranged laterally. The connecting plate is distributed on the upper and lower sides of the adjusting rod and is arranged linearly. The connecting rod is hinged between the adjusting block and the connecting plate. The insert is fixedly connected to the connecting plate, and its end passes through the cylinder and is slidably connected to it.

[0013] Furthermore, the feeding assembly includes a stepper motor, a feeding cylinder, and a guide cylinder. The stepper motor is fixedly mounted on the frame. One end of the feeding cylinder is fixedly connected to the output end of the stepper motor, and the other end is rotatably connected to the frame. The guide cylinder is rotatably connected between the inner walls of the frame and is symmetrically distributed on one side of the rotating cylinder.

[0014] Furthermore, the inner wall of the winding drum is provided with positioning grooves, which are symmetrically distributed, and the positioning grooves are adapted to the insert blocks.

[0015] Furthermore, the cylinder is provided with limiting strips, which are symmetrically distributed, and the winding drum and the limiting strips are slidably connected.

[0016] Furthermore, the take-up drum is provided in multiple sets, with gaps between the take-up drums, and the slitting blades correspond to the gaps. A brushless motor is fixedly installed on the frame, and its output end is fixedly connected to one end of the cylinder.

[0017] The beneficial effects of this utility model after adopting the above structure are as follows:

[0018] (1) The limiting strip guides the insertion of the winding drum. The rotation of the adjusting rod causes multiple adjusting blocks to move relative to each other, thereby causing the top of the connecting plate to move vertically under the action of the connecting rod and the contact surface between the cylinder and the block until it is inserted into the positioning groove, thus positioning the winding drum and solving the problem of uneven winding caused by the random placement of the winding sleeve.

[0019] (2) The feeding cylinder releases the tape, the rotating drum drives the slitting blade to slit the tape, the brushless motor drives the cylinder to rotate to wind the tape, and after winding is completed, the servo motor is controlled to reverse so that the insert block leaves the slot and the winding drum is pulled out.

[0027] like Figure 1-2 As shown, a slitting machine for tape processing includes a frame 1 and a top frame 2. Two sets of top frames are symmetrically arranged on the frame 1. The top frame 2 is fixedly connected to the top of the frame 1 and is arranged in a U-shape. The machine also includes a feeding assembly, a tensioning slitting assembly, and a winding assembly. The feeding assembly is located on the frame 1 and is used for feeding the tape. The tensioning slitting assembly is located on the top frame 2 and the frame 1, and includes a pressure cylinder 3 that moves vertically below the top frame 2, a rotating drum 4 rotatably connected between the inner walls of the frame 1, and slitting blades 5 fixedly connected to the rotating drum 4. The rewinding assembly is mounted on the frame 1 for slitting tape. It includes a cylinder 6 rotatably connected to the frame 1, a rewinding drum 7 horizontally slidably mounted on the cylinder 6, and a positioning mechanism located inside the cylinder 6 for rewinding tape. Multiple sets of rewinding drums 7 are provided. Limiting strips 19 are provided on the cylinder 6 and are symmetrically distributed. The rewinding drum 7 and the limiting strips 19 are slidably connected to facilitate inserting the rewinding drum 7 into the cylinder 6. A brushless motor 11 is fixedly mounted on the frame 1, and its output end is fixedly connected to one end of the cylinder 6.

[0028] like Figure 1-3 As shown, to facilitate the tape feeding operation, the feeding assembly includes a stepper motor 20, a feeding cylinder 21, and a guide cylinder 22. The stepper motor 20 is fixedly mounted on the frame 1. One end of the feeding cylinder 21 is fixedly connected to the output end of the stepper motor 20, and the other end is rotatably connected to the frame 1. The guide cylinder 22 is rotatably connected between the inner walls of the frame 1 and is symmetrically distributed on one side of the rotating drum 4. It is connected to the connecting plate 15, and its end passes through the cylinder 6 and is slidably connected to it. The feeding cylinder 21 rotates at a uniform speed, and the guide cylinder 22 guides the end of the tape, enabling it to feed in an orderly manner.

[0029] like Figure 1-4 As shown, to ensure the slitting operation, the tensioning and slitting assembly includes an electric push rod 8, a connecting frame 9, and a rotary motor 10. The electric push rod 8 vertically penetrates the top frame 2 and is fixedly connected to it, with its output end located below the top frame 2 and between the frame 1. The connecting frame 9 is fixedly connected to the free end of the electric push rod 8 and is arranged in a U-shape. The pressure cylinder 3 is rotatably connected between the inner walls of the connecting frame 9. The rotary motor 10 is fixedly installed on the frame 1, and its output end is fixedly connected to one end of the rotating drum 4. The slitting blades 5 are symmetrically distributed on the rotating drum 4, and there are gaps between the take-up drums 7. The slitting blades 5 correspond to the gaps. By controlling the movement of the pressure cylinder 3 through the electric push rod 8, the tension of the tape can be increased, thereby ensuring the slitting effect of the tape by the slitting blades 5 on the rotating drum 4.

[0030] like Figure 1-5 As shown, to facilitate the installation and replacement of the winding drum 7 and ensure the winding effect, the positioning mechanism includes a servo motor 12, an adjusting rod 13, an adjusting block 14, a connecting plate 15, a connecting rod 16, and an insert block 17. The servo motor 12 is fixedly installed at the end of the cylinder 6. One end of the adjusting rod 13 is fixedly connected to the output end of the servo motor 12, and the other end is rotatably connected to the inner wall of the cylinder 6. The adjusting rod 13 is provided with multiple sets of bidirectional threads. The adjusting block 14 is threadedly connected to the adjusting rod 13 and is arranged laterally. The connecting plate 15 is distributed on the upper and lower sides of the adjusting rod 13 and is arranged linearly. The connecting rod 16 is hinged to the adjusting block. Between 14 and connecting plate 15, the insert 17 is fixedly connected to the connecting plate 15, and its end passes through the cylinder 6 and is slidably connected to it. The inner wall of the take-up drum 7 is provided with positioning grooves 18, which are symmetrically distributed. The positioning grooves 18 and the insert 17 are adapted to each other. The rotation of the adjusting rod 13 causes multiple adjusting blocks 14 to move relative to each other, thereby causing the insert 17 at the top of the connecting plate 15 to move vertically under the action of the connecting rod 16 and the contact surface between the cylinder 6 and the insert 17, until it is inserted into the positioning groove 18. The take-up drum 7 can then be positioned and the installation operation can be completed. The reversal of the adjusting rod 13 can cause the insert 17 to leave the positioning groove 18 and the removal operation can be completed.

[0031] In practical use, after aligning the take-up drum 7 with the limiting strip, insert it sequentially onto the cylinder 6. Align the take-up drum 7 with the gap between the slitting blade 5 and the frame 1, and with the gap between the slitting blades 5. Then, turn on the servo motor 12. The rotation of the adjusting rod 13 causes multiple adjusting blocks 14 to move relative to each other. This causes the insert block 17 at the top of the connecting plate 15 to move vertically under the action of the connecting rod 16 and the contact surface between the cylinder 6 and the insert block 17, until it is inserted into the positioning groove 18. This positions the take-up drum 7, solving the problem of arbitrary placement of the take-up sleeve. To address the issue of uneven winding, one end of the tape is wrapped around the guide cylinder 22 and the slitting blade, and its end is pre-cut. The cut tape end is then fixed to the winding drum 7. Simultaneously, the stepper motor 20, the rotary motor 10, and the brushless motor 11 are turned on. The feed cylinder 21 releases the tape, the rotary drum 4 drives the slitting blade 5 to slit the tape, and the brushless motor 11 drives the cylinder 6 to rotate and wind the tape. After winding is completed, the servo motor 12 is reversed, which causes the insert block 17 to leave the slot and the winding drum 7 to be pulled out.
