Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and particularly to a conveying structure and a double-sided adhesive production line. Background Art

[0002] Double-sided adhesives are widely used in sanitary napkins and other products. The production of double-sided adhesives requires multiple processes. Among them, after a small roll of double-sided adhesive is formed, usually multiple smaller rolls of double-sided adhesives are formed into a large roll by splicing and continuous winding to facilitate transfer to the next working station. Currently, when a roll of double-sided adhesive is completely unwound, it is necessary for workers to splice the next roll of double-sided adhesive to the end of the previous roll and fix the two together by hot melting. Such operation is rather cumbersome and difficult to improve production efficiency. Therefore, there is an urgent need for a structure that can splice double-sided adhesives during conveying, so as to improve the overall production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a conveying structure and a double-sided adhesive production line to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution of the present invention to solve its technical problems is as follows:

[0005] A conveying structure includes: a winding device having a rotatable winding roller; a conveying device having a conveyer belt capable of rotary motion, and a conveying surface moving towards the winding roller is formed on the top side of the conveyer belt; a transfer unit including a transfer frame, an unwinding roller, a transfer roller, a separating component, a cutting component and a pressing component. The unwinding roller and the transfer roller are respectively rotatably connected to the transfer frame. The pressing component has a pressing plate that can move downward close to the conveying surface or upward away from the conveying surface. The separating component is located between the unwinding roller and the transfer roller. The coil on the unwinding roller can be unwound, pass through the transfer roller and be led to the lower side of the pressing plate. The separating component is used for separating the release paper on the coil, and the cutting component is used for cutting the separated release paper.

[0006] The technical solution has at least the following beneficial effects: Load the double-sided adhesive tape coil that needs to be unwound and spliced into the unwinding roller. After unwinding the coil and passing it through the transfer roller, tear the release paper on the coil to the separation component, and the part of the coil from which the release paper is torn is continuously led to the lower side of the pressing plate. At this time, after the release paper is torn from the coil on the bottom side of the pressing plate, the exposed adhesive surface of this part faces downward, and the winding roller is used to wind the coil. After the winding of the previous coil is completed, the end part of this coil is still located on the conveying surface. When it is necessary to splice two coils together, the pressing plate moves downward to press the head end of the next coil against the end of the previous coil, and uses the adhesive surface of the next coil to bond and fix the two, and then the pressing plate moves up a certain distance to remove the pressure directly pressing the coil against the conveying surface. The conveyor belt moves, the unwinding roller rotates to unwind, and the winding roller rotates to wind. At this time, the separation component continuously separates the release paper from the coil passing through the transfer roller, so that the adhesive surface of the coil can continue to bond to the end part of the previous coil. Then the cutting component cuts the separated release paper to stop separating the release paper from the coil continuously. The pressing plate can move upward to reset. The unwinding roller releases a complete coil onto the conveyor belt, and the conveyor belt keeps the coil steadily transferred to the winding roller to realize the winding of the coil. In this way, by separating a part of the release paper from the next coil and directly connecting it to the tail of the previous coil by bonding, the splicing of two coils can be realized during the transportation by the conveyor belt, effectively improving the transportation efficiency.

[0007] As a further improvement of the above technical solution, the separation component includes a separation roller and a feeding roller respectively rotatably connected to the transfer frame. A first material passing gap is formed between one side of the top of the separation roller and the transfer roller. There are two feeding rollers arranged in the vertical direction, and a second material passing gap for sending out the release paper is formed between the two feeding rollers. The coil unwound from the unwinding roller passes through the first material passing gap. When the coil enters the first material passing gap, the release paper on the coil is separated from the separation roller. The separation roller can be used to guide the release paper and the coil from which the release paper is separated, so that the release paper is led to the second material passing gap after passing through, and the two feeding rollers are rotated to send out the release paper, while the coil from which the release paper is separated is led to the transfer roller. In this way, it is convenient to guide the coil and the release paper, and the release paper can be continuously sent outwards.

[0008] As a further improvement of the above technical solution, a pressure roller is rotatably connected to the transfer frame. A third material passing gap is formed between one side of the bottom of the pressure roller and the transfer roller. The coil unwound from the unwinding roller is led to the lower side of the pressing plate after passing through the third material passing gap. The coil from which the release paper is separated or the complete coil can be led to pass through the third material passing gap. Using the pressure roller to press the coil against the transfer roller can better guide the coil to be sent out, especially when the complete coil is released onto the conveyor belt, the stability is higher.

[0009] As a further improvement of the above technical solution, a guide plate is connected above the pressure roller of the transfer rack, and the guide plate is inclined downward from top to bottom in the direction close to the transfer roller. When it is not necessary to separate the release paper, the release paper is cut off by the cutting assembly. At this time, a part of the end of the release paper is separated from the surface of the coil. When passing through the guide plate, the inclined guide of the guide plate can make the release paper close to the surface of the coil, so that it can be closely attached to the surface of the coil again when entering the third material passing gap, effectively preventing the separated release paper from curling.

[0010] As a further improvement of the above technical solution, the cutting assembly includes a cutting driving member and a cutter. The cutting driving member is connected to the transfer rack, and the cutting driving member is drivingly connected to the cutter. The cutting driving member can drive the cutter to move in a direction close to or away from the transfer roller. When the release paper is separated, the cutting driving member drives the cutter to a state away from the transfer roller. When it is necessary to cut the release paper, the cutting driving member drives the cutter close to the transfer roller to cut the release paper led out to the separation assembly.

[0011] As a further improvement of the above technical solution, a cutting edge is provided on the side of the cutter facing the transfer roller, and both ends of the cutting edge are inclined away from the transfer roller towards the center. When the cutter approaches the release paper, both sides of the cutting edge first come into contact with both sides of the release paper respectively, which can effectively limit the position of the release paper and prevent the release paper from shifting. As the cutting driving member drives the cutting edge to gradually approach the transfer roller, the release paper can be gradually pressed, so as to cut the release paper from both sides to the center.

[0012] As a further improvement of the above technical solution, the pressing assembly includes a pressing driving member connected to the transfer rack. The pressing driving member is drivingly connected to the pressing plate. The pressing driving member can drive the pressing plate to move up and down. A first negative pressure source is connected to the top side of the pressing plate, and a plurality of first negative pressure holes are provided on the bottom side of the pressing plate. The first negative pressure source is connected to the plurality of first negative pressure holes through a pipeline. When the coil is led to the bottom side of the pressing plate, the first negative pressure source is started, so that a negative pressure is formed at the plurality of first negative pressure holes to adsorb the coil, so that the coil can be kept relatively fixed at the bottom side of the pressing plate. When the pressing plate presses the coil down to be spliced with the end of the previous coil, the first negative pressure source stops generating negative pressure at the first negative pressure holes, and the negative pressure suction force on the coil is removed.

[0013] As a further improvement of the above technical solution, a negative pressure box is provided in the conveying device, the negative pressure box is connected to a second negative pressure source through a pipeline, a connecting hole is provided on the top side of the negative pressure box, and a plurality of second negative pressure holes are provided on the conveyor belt. When the coil is conveyed on the conveyor belt, the second negative pressure source forms a negative pressure on the negative pressure box, so that a negative pressure suction force is formed at the plurality of second negative pressure holes on the conveyor belt, so that the coil can be closely attached to the conveyor belt, unfolded and laid flat on the conveyor belt, and the coil can be stably sent to the winding roller as the conveyor belt rotates.

[0014] As a further improvement of the above technical solution, the present invention also includes a base frame, the base frame is connected with a translation drive, the translation drive is connected with a translation seat, at least two transfer units are arranged on the translation seat, the translation drive can drive the translation seat to reciprocate in the horizontal direction and make at least one of the transfer units face the conveyor belt. During operation, one transfer unit faces the conveyor belt to realize the splicing and unwinding of the coiled material, while the other transfer unit is staggered with the conveyor belt, and the winding roller in the transfer unit can be loaded and unloaded to realize the timely replenishment of the coiled material. After the unwinding of the transfer unit with the conveyor belt is completed, the translation drive drives the translation seat to face the replenished transfer unit to the conveyor belt, which can save the replenishment time and further improve the overall production efficiency.

[0015] A double-sided adhesive tape production line comprises the above-mentioned conveying structure.

[0016] This technical solution has at least the following beneficial effects: in this double-sided adhesive production line, the conveying structure separates part of the release paper from the next roll and directly connects it with the tail of the previous roll by bonding, so that the two rolls can be spliced during the conveying process using the conveyor belt, effectively improving the conveying efficiency, thereby making the overall production more efficient.

Detailed implementation manners

[0021] The concept, specific structure and technical effects of the present invention will be clearly and completely described below in combination with the embodiments and the accompanying drawings to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present invention. In addition, all the connection relationships mentioned in the text do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined with each other without conflicting with each other.

[0022] Refer to Figure 1 And Figure 2 , a conveying structure, comprising: a winding device having a rotating winding roller 1; a conveying device having a rotatable conveyor belt 21, a conveying surface moving towards the winding roller 1 being formed on the top side of the conveyor belt 21; a transfer unit including a transfer rack 31, an unwinding roller 32, a transfer roller 33, a separating assembly, a cutting assembly and a pressing assembly. The unwinding roller 32 and the transfer roller 33 are respectively rotatably connected to the transfer rack 31. The pressing assembly has a pressing plate 341 that can move downwards close to the conveying surface or upwards away from the conveying surface. The separating assembly is located between the unwinding roller 32 and the transfer roller 33. The coil on the unwinding roller 32 can be unwound through the transfer roller 33 and led to the lower side of the pressing plate 341. The separating assembly is used to separate the release paper on the coil, and the cutting assembly is used to cut the separated release paper. Naturally, in order to drive the unwinding roller 32, the transfer roller 33 and the winding roller 1 to rotate, motors are respectively configured to provide rotational driving forces for the unwinding roller 32, the transfer roller 33 and the winding roller 1.

[0023] In this conveying structure, the double-sided adhesive roll material that needs to be unwound and spliced is loaded into the unwinding roller 32. After the roll material is unwound and passes through the transfer roller 33, the release paper on the roll material is torn out to the separation assembly. The part of the roll material from which the release paper is torn out continues to be guided to the lower side of the pressing plate 341. At this time, after the release paper is torn out from the roll material on the bottom side of the pressing plate 341, the exposed adhesive surface of this part faces downward, and the winding roller 1 is used to wind the roll material. After the winding of the previous roll material is completed, the end part of this roll material still remains on the conveying surface. When it is necessary to splice two roll materials together, the pressing plate 341 moves downward to press the head end of the next roll material tightly against the end of the previous roll material, and the adhesive surface of the next roll material is used to bond and fix the two. Then the pressing plate 341 moves upward a certain distance to remove the pressure of directly pressing the roll material against the conveying surface. The conveyor belt 21 moves, the unwinding roller 32 rotates to unwind, and the winding roller 1 rotates to wind. At this time, the separation assembly continuously separates the release paper from the roll material passing through the transfer roller 33 so that the adhesive surface of the roll material can continue to bond to the end part of the previous roll material. Then the cutting assembly cuts the separated release paper to stop the continuous separation of the release paper from the roll material. The pressing plate 341 can move upward to reset. The unwinding roller 32 releases the complete roll material onto the conveyor belt 21, and the conveyor belt 21 keeps the roll material stably transferred to the winding roller 1 to realize the winding of the roll material. In this way, by separating part of the release paper from the next roll material and directly connecting it to the tail of the previous roll material by bonding, the splicing of two roll materials can be realized during the conveying process of the conveyor belt 21, effectively improving the conveying efficiency.

[0024] In practical applications, in order to prevent the roll material from adhering to the transfer roller 33 and the pressing plate 341, some anti-adhesion measures can be taken on the transfer roller 33 and the pressing plate 341. For example, the surfaces of the transfer roller 33 and the pressing plate 341 in contact with the roll material are smooth surfaces, or an anti-adhesive coating can be further added.

[0025] The separating component is mainly used to pull out the separated release paper. In this embodiment, the separating component includes a separating roller 351 and a feeding roller 352 that are respectively rotatably connected to the transfer frame 31. A first material passing gap is formed between one side of the top of the separating roller 351 and the transfer roller 33. There are two feeding rollers 352 arranged in the vertical direction. A motor is configured on the transfer frame 31 to provide driving force to the two feeding rollers 352 simultaneously. A second material passing gap for sending out the release paper is formed between the two feeding rollers 352. The coil material unrolled from the unwinding roller 32 passes through the first material passing gap. When the coil material enters the first material passing gap, the release paper on the coil material is separated from the separating roller 351. The separating roller 351 can be used to guide the release paper and the coil material from which the release paper is separated, so that the release paper is led to the second material passing gap after passing through. The two feeding rollers 352 rotate to send out the release paper, and the coil material from which the release paper is separated is led to the transfer roller 33. In this way, it is convenient to guide the coil material and the release paper, and the release paper can be continuously sent outwards.

[0026] In order to stably send out the coil material after passing through the transfer roller 33, in this embodiment, a pressing roller 36 is rotatably connected to the transfer frame 31. A third material passing gap is formed between one side of the bottom of the pressing roller 36 and the transfer roller 33. The coil material unrolled from the unwinding roller 32 is led to the lower side of the pressing plate 341 after passing through the third material passing gap. The coil material from which the release paper is separated or the complete coil material can be led to pass through the third material passing gap. The pressing roller 36 presses the coil material against the transfer roller 33, which can better guide and send out the coil material. Especially when the complete coil material is released onto the conveyor belt 21, the stability is higher.

[0027] When the separated release paper directly passes through the transfer roller 33 and is directly sent to the conveyor belt 21, the release paper is easily pressed and folded on the conveyor belt 21, thus affecting the tightness of the final winding. Therefore, in this embodiment, a guide plate 37 is connected above the pressing roller 36 on the transfer frame 31. The guide plate 37 is inclined downward from top to bottom towards the direction close to the transfer roller 33. When it is not necessary to separate the release paper, the release paper is cut by the cutting component. At this time, a part of the end of the release paper is separated from the surface of the coil material. When passing through the guide plate 37, the inclined guide of the guide plate 37 can make the release paper close to the surface of the coil material, so that it closely adheres to the surface of the coil material again when entering the third material passing gap, effectively preventing the separated release paper from curling.

[0028] The cutting component is used to cut the release paper. Specifically, the cutting component includes a cutting driving member 381 and a cutter 382. The cutting driving member 381 is connected to the transfer frame 31, and the cutting driving member 381 is drivingly connected to the cutter 382. The cutting driving member 381 can drive the cutter 382 to move in a direction close to or away from the transfer roller 33. The cutting driving member 381 can be a cylinder, an electric lead screw, a hydraulic cylinder, etc. When the release paper is being separated, the cutting driving member 381 drives the cutter 382 to a state away from the transfer roller 33. When it is necessary to cut the release paper, the cutting driving member 381 drives the cutter 382 to approach the transfer roller 33 to cut the release paper led to the separation component.

[0029] Further, a cutting edge is provided on the side of the cutter 382 facing the transfer roller 33, and both ends of the cutting edge are inclined away from the transfer roller 33 towards the center. When the cutter 382 approaches the release paper, both sides of the cutting edge first come into contact with both sides of the release paper respectively, which can effectively limit the position of the release paper and prevent the release paper from shifting. As the cutting driving member 381 drives the cutting edge to gradually approach the transfer roller 33, the release paper can be gradually pressed, thereby realizing cutting the release paper from both sides to the center.

[0030] When the coil is led to the bottom side of the pressing plate 341, it is necessary to relatively position the coil at the bottom side of the pressing plate 341. The leading end portion of the coil can be turned up and directly bonded to the bottom side of the pressing plate 341. In order to improve the convenience of use, in this embodiment, the pressing component includes a pressing driving member 342 connected to the transfer frame 31. The pressing driving member 342 is drivingly connected to the pressing plate 341. The pressing driving member 342 can drive the pressing plate 341 to move up and down. The pressing driving member 342 can be a cylinder, an electric lead screw, a hydraulic cylinder, etc. A first negative pressure source 343 is connected to the top side of the pressing plate 341, and a plurality of first negative pressure holes are provided on the bottom side of the pressing plate 341. The first negative pressure source 343 is connected to the plurality of first negative pressure holes through a pipeline. When the coil is led to the bottom side of the pressing plate 341, the first negative pressure source 343 is started, so that a negative pressure is formed at the plurality of first negative pressure holes to adsorb the coil. In this way, the coil can be kept in a state of being relatively fixed to the bottom side of the pressing plate 341. When the pressing plate 341 presses the coil down to be spliced with the end of the previous coil, the first negative pressure source 343 stops generating negative pressure at the first negative pressure holes, and the negative pressure suction force on the coil is removed.

[0031] When the coil is guided to the conveyor belt 21, the friction between the coil and the conveyor belt 21 can drive the coil to slide on the conveyor belt 21. In order to improve the stability of the coil transportation, in this embodiment, a negative pressure box 22 is provided in the conveying device, and the negative pressure box 22 is connected to the second negative pressure source through a pipeline. A connecting hole is provided on the top side of the negative pressure box 22, and a plurality of second negative pressure holes are provided on the conveyor belt 21. When the coil is transported on the conveyor belt 21, the second negative pressure source forms a negative pressure on the negative pressure box 22, so that a negative pressure suction force is formed at the plurality of second negative pressure holes on the conveyor belt 21, so that the coil can be closely attached to the conveyor belt 21, unfolded and laid flat on the conveyor belt 21, and the coil can be stably sent to the winding roller 1 as the conveyor belt 21 rotates.

[0032] The present invention also includes a base frame 41, on which a translation drive 42 is connected, and the translation drive 42 is driven to be connected to a translation seat, and at least two transfer units are arranged on the translation seat, and the translation drive 42 can drive the translation seat to reciprocate in the horizontal direction and make at least one of the transfer units face the conveyor belt 21, and the translation drive 42 can be a cylinder, a hydraulic cylinder or an electric screw. During operation, one transfer unit faces the conveyor belt 21 to achieve the splicing and unwinding of the coiled material, while the other transfer unit is staggered with the conveyor belt 21, and the unwinding roller 32 in the transfer unit can be loaded and unloaded to achieve the timely replenishment of the coiled material. When the transfer unit facing the conveyor belt 21 is unwound, the translation drive 42 drives the translation seat to face the replenished transfer unit to the conveyor belt 21, which can save the replenishing time and further improve the overall production efficiency.

[0033] A double-sided adhesive tape production line comprises the above-mentioned conveying structure.

[0034] In this double-sided tape production line, the conveying structure separates part of the release paper from the next roll and directly connects it to the tail of the previous roll by bonding, so that the two rolls can be spliced during the conveying process using the conveyor belt 21, effectively improving the conveying efficiency and making the overall production more efficient.
