Description

Technical Field

[0001] The invention relates to the technical field of material cutting, in particular to a coiled tape cutting machine. Background Art

[0002] Most tapes are stored in rolls. In industrial production, the rolls need to be cut into sheets before they are applied to equipment or products. Currently, when cutting the tape, there is either a problem of not cutting in place and causing the tape to stick to the roll, or after cutting in place, the tape sheet is very likely to stick to the output structure. This will affect the material collection of the tape sheet, and will directly affect production efficiency and quality. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned problems of the prior art and provide a roll material tape cutting machine. Through the setting of the traction unit, the conveying work of the roll material tape can be realized; through the cooperation of the cutting unit and the material receiving frame, the sheet material tape and the roll material tape can be separated; through the setting of the up and down moving ejection frame, the sheet material tape can be lifted up and separated from the material receiving strip. In this way, it can ensure efficient cutting of the tape and stable material removal of the sheet material tape.

[0004] The purpose of the present invention is mainly achieved through the following technical solutions:

[0005] The roll material adhesive tape cutting machine comprises a bearing base, on which a roll material installation unit, a pulling unit, a cutting unit and a separation unit are installed from the back to the front;

[0006] The coil installation unit comprises a coil installation frame, on which a coil support shaft is rotatably arranged;

[0007] The traction unit includes a traction roller, a tension roller matched with the traction roller, and a traction drive assembly for driving the traction roller to rotate;

[0008] The separation unit includes a front and rear drive assembly, the output ends of which are connected to a material receiving frame spaced apart from the traction unit, and the front and rear drive assemblies act on the material receiving frame so that: the material receiving frame can move forward and backward relative to the supporting base; a plurality of material receiving strips spaced apart are arranged on the material receiving frame, and the plurality of material receiving strips together form a material receiving channel; an upper and lower drive assembly is installed on the material receiving frame, the output ends of the upper and lower drive assemblies are connected to an ejection frame, and a plurality of non-stick strips staggered with the plurality of material receiving strips are arranged on the ejection frame, and the non-stick strips can be placed in the area between two adjacent material receiving strips, and the upper and lower drive assemblies act on the ejection frame so that: the non-stick strips can move up and down relative to the material receiving strips; a non-stick layer is arranged on the top of the non-stick strips;

[0009] The cutting unit comprises a tool connecting frame and a cutting driving assembly for driving the tool connecting frame to move up and down. The tool connecting frame is provided with a blade located in the area between the separation unit and the traction unit.

[0010] When the present invention is used, the coiled material tape is loaded on the coiled material support shaft, and one end of the tape is pulled to pass over the top of the traction roller and between the traction roller and the tension roller, and then enters the material receiving channel from below the tension roller. When the present invention is in the zero position state, the non-stick strip is located below the material receiving strip, and the material receiving frame is located near the traction unit, but is still spaced apart from the traction unit. Start the traction drive assembly to drive the traction roller to rotate, so that the tape can be pushed forward. When the length of the tape covered on the splicing strip meets a specific value, start the cutting drive assembly to drive the tool connecting frame to move downward. At the same time, start the front and rear drive assemblies to drive the splicing frame to move forward. Since the sheet tape has a certain viscosity, it will move forward together with the splicing strip. This can provide a certain tension to the tape, and the blade can cut the tape to form a sheet tape. At the same time, it can also ensure that the aforementioned sheet tape can be separated from the tape at the traction unit. Then start the upper and lower drive assemblies to drive the ejection frame to move upward until the non-stick strip can lift the sheet tape upward and separate it from the splicing strip. Since the non-stick strip is provided with a non-stick layer in contact with the sheet tape, the sheet tape can be easily taken out and processed.

[0011] Furthermore, limit slide bars are provided on both the left and right sides of the material receiving rack;

[0012] The bearing base is provided with a limiting sliding groove which can slidably cooperate with the limiting sliding bar.

[0013] In the present invention, the stability of the forward and backward movement of the material receiving rack can be improved by setting the limiting sliding bar and the limiting sliding groove.

[0014] Furthermore, a position sensor is installed at the rear end of the supporting base.

[0015] In the present invention, by setting a position sensor, it is possible to monitor whether the length of the adhesive tape covering the splicing strip meets a specific value.

[0016] In order to realize the driving of the front and rear drive components to move forward and backward with the material rack, the front and rear drive components further include front and rear drive motors, front and rear active transmission wheels connected to the output ends of the front and rear drive motors, front and rear driven transmission wheels rotatably arranged on the bearing base, and front and rear transmission belts sleeved on the front and rear active transmission wheels and the front and rear driven transmission wheels;

[0017] The material receiving rack is connected with the front and rear driving belts through a transmission connecting piece.

[0018] In the present invention, the front and rear drive motors are started to move the front and rear drive belts, thereby driving the material receiving frame to move forward and backward.

[0019] In order to improve the stability of the movement of the receiving rack, further, a conveying limit slider is provided at the bottom end of the receiving rack;

[0020] The bearing base is provided with a transmission limiting slide rail which is slidably matched with the transmission limiting slider.

[0021] Furthermore, an ejection limiting slider is provided on the ejection frame;

[0022] The material receiving frame is provided with an ejection limiting slide rail which is slidably matched with the ejection limiting slide block.

[0023] In the present invention, the stability of the ejection frame moving up and down can be improved by arranging the ejection limiting slide rail and the ejection limiting sliding block.

[0024] In order to realize the rotational drive of the traction roller, the traction drive assembly further includes a traction drive motor, a traction active transmission wheel connected to the output end of the traction drive motor, a traction driven transmission wheel sleeved on the traction roller, and a traction drive belt sleeved on the traction active transmission wheel and the traction driven transmission wheel.

[0025] Furthermore, a cutting transmission opening is provided on the tool connecting frame;

[0026] The cutting drive assembly comprises a cutting drive motor, the output end of the cutting drive motor is connected to a cutting connection piece, a cutting drive column is eccentrically arranged on the cutting connection piece and is inserted into a cutting drive opening, and the cutting drive column can slide in the cutting drive opening;

[0027] The bearing base is also provided with a cutting limit frame for limiting the position of the tool connecting frame.

[0028] In the present invention, the cutting drive motor is started to drive the cutting connection member to rotate. As the height position of the cutting transmission column changes, the cutting connection member cooperates with the cutting transmission opening to drive the tool connection frame and the blade to move up and down, so that the coil material can be cut. The cutting limit frame is set to limit the up and down movement of the tool connection frame to avoid position deviation during cutting and affect the cutting stability.

[0029] In order to realize the driving of the ejection frame by the upper and lower driving components to move up and down, the bottom end of the ejection frame is connected to an ejection connecting frame, and an ejection transmission opening is opened on the ejection connecting frame;

[0030] The up and down driving assembly comprises an ejection rotary motor, the output end of which is connected to an ejection connecting piece, an ejection transmission column which is eccentrically arranged on the ejection connecting piece and is inserted into an ejection transmission opening, and the ejection transmission column can slide in the ejection transmission opening.

[0031] In the present invention, starting the ejection rotating motor can drive the ejection connecting member to rotate, and as the height position of the ejection transmission column changes, the ejection connecting frame and the ejection frame can be driven to move up and down.

[0032] Furthermore, a plurality of annular notches are arranged on the outer surfaces of the traction roller and the tension roller.

[0033] In the present invention, the contact area between the adhesive tape, the traction roller and the tension roller can be reduced by setting the annular notch, so that the reliability of the adhesive tape transmission can be improved.

[0034] The present invention has the following beneficial effects:

[0035] 1. In the present invention, the conveying work of the roll material tape can be realized by setting the traction unit; the separation of the sheet material tape and the roll material tape can be realized by the cooperation of the cutting unit and the material receiving frame; the sheet material tape can be lifted up and separated from the material receiving strip by setting the ejection frame moving up and down. In this way, the efficient cutting work of the tape can be ensured, and the stable material taking work of the sheet material tape can be carried out.

[0036] 2. In the present invention, the stability of the forward and backward movement of the material receiving rack can be improved by setting the limit slide bar and the limit slide groove and setting the transmission limit slide block and the transmission limit slide rail.
