Description

A gluing device for insulating paper production Technical Field

[0001] This utility model relates to the field of gluing equipment technology, specifically a gluing equipment for insulating paper production. Background Technology

[0002] A glue applicator, also known as a dispensing machine, coating machine, or dripping machine, is specifically designed to control fluids and apply them drop by drop to the surface of different products to improve product quality and functionality. The glue application method is determined according to the product requirements.

[0003] According to a public notice (CN 214637754U) regarding a gluing device for producing diamond-patterned insulating paper, the aforementioned application describes a hollow rubber roller with a strip-shaped slit in the middle. When a special modified epoxy resin enters the roller, it is absorbed by the suction layer through the slit. The suction layer includes a sponge layer and a polypropylene storage layer. The outermost end of the suction layer has a diamond-patterned plastic mesh, which possesses a certain degree of elasticity and toughness, making it resistant to damage. At the end of the roller that contacts the diamond-patterned mesh, there is a detachable threaded ring. The threaded ring is an open ring with internal threads, and the corresponding position on the roller also has threads. This allows for the replacement of diamond-patterned meshes of different thicknesses. When the threaded ring is tightened, it also provides axial fixation for the diamond-patterned mesh.

[0004] However, changing to different thicknesses of diamond-patterned mesh requires removing the rubber roller, taking off the threaded ring, replacing the mesh, reassembling the rubber roller, and reinstalling it. The rubber roller is connected to the fixed plate via a rotating bearing; disassembly requires disconnecting the motor drive and removing the material feed pipe sealing structure. If frequent adjustments to the adhesive thickness are needed during production, this will significantly reduce production line efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a gluing device for insulating paper production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gluing device for insulating paper production, comprising a base, two sets of symmetrically arranged side plates fixedly connected to the surface of the base, through holes being opened on the side walls of the two sets of side plates, and connecting shafts being rotatably connected to the through holes, a gluing assembly being arranged between the two sets of connecting shafts, the gluing assembly comprising an inner cylinder, the inner cylinder being fixedly connected between the two sets of connecting shafts, multiple sets of arrayed glue outlet grooves being opened on the outer wall of the inner cylinder, a sponge layer being sleeved on the outer wall of the inner cylinder, two sets of semi-cylinders being sleeved on the outer wall of the glue outlet grooves, multiple sets of arrayed rhomboid holes being opened on the surface of the two sets of semi-cylinders, and positioning holes being opened at the ends of the two sets of semi-cylinders.

[0007] Preferably, a positioning component is provided on the outer wall of the inner cylinder. The positioning component includes a fixing ring, which is fixedly connected to the inner wall of the inner cylinder. Multiple sets of arrayed telescopic rods are fixedly connected to the side wall of the fixing ring. A collar is fixedly connected to the end of the telescopic rod. A positioning pin is fixedly connected to the side wall of the collar. The positioning pin is inserted into the inside of the positioning hole.

[0008] Preferably, the fixing ring and the collar are elastically connected by a spring, and the spring is sleeved on the outer wall of the telescopic rod.

[0009] Preferably, a glue delivery tube is rotatably connected to the end of one set of connecting shafts, a motor is fixedly connected to the side wall of the side plate, and the output shaft of the motor is fixedly connected to the end of another set of connecting shafts.

[0010] Preferably, a groove is formed on the side wall of one set of the semi-cylinders, and a magnetic strip is fixedly connected inside the groove.

[0011] Preferably, a protruding strip is fixedly connected to the side wall of another set of the semi-cylinders, the protruding strip being inserted into the inside of the groove and magnetically connected to the magnetic strip.

[0012] Compared with the prior art, this utility model provides a gluing device for insulating paper production, which has the following advantages:

[0013] 1. This adhesive applicator for insulating paper production uses two sets of semi-cylinders to achieve rapid splicing and disassembly with the help of convex strips, grooves, and magnetic strips. With the elastic positioning of springs, telescopic rods, and positioning pins in the positioning component, the semi-cylinders are stably connected during adhesive application. The positioning can be quickly released by pressing the collar, which facilitates the cleaning and replacement of residual adhesive in the sponge layer or inner cylinder and semi-cylinders, reducing the time cost and operation difficulty of equipment maintenance.

[0014] 2. The glue applicator used in the production of insulating paper has an inner cylinder that stably supplies glue to the sponge layer through an array of glue outlet grooves, so that the sponge layer is evenly saturated with glue; the diamond-shaped holes of the outer semi-cylinder provide a channel for the glue to be transferred to the insulating paper, and also avoid glue accumulation caused by the sponge layer directly contacting the insulating paper over a large area.

[0020] As shown in Figures 1-4, this utility model provides a technical solution: a gluing device for insulating paper production, including a base 1. Two sets of symmetrically arranged side plates 2 are fixedly connected to the surface of the base 1. Through holes are opened on the side walls of the two sets of side plates 2, and a connecting shaft 21 is rotatably connected to each through hole. A glue application assembly 3 is arranged between the two sets of connecting shafts 21. A glue delivery pipe 22 is rotatably connected to the end of one set of connecting shafts 21. A motor 23 is fixedly connected to the side wall of the side plate 2. The output shaft of the motor 23 is fixedly connected to the end of the other set of connecting shafts 21. After the motor 23 is started, its output shaft drives the one set of connecting shafts 21 to rotate. The connecting shafts 21 then drive the glue application assembly 3 to rotate as a whole, providing power for glue application. The glue delivery pipe 22 can continuously deliver glue into the inner cylinder 31 when the connecting shafts 21 rotate.

[0021] The adhesive application assembly 3 includes an inner cylinder 31, which is fixedly connected between two sets of connecting shafts 21. Multiple arrays of adhesive dispensing grooves 32 are formed on the outer wall of the inner cylinder 31. A sponge layer 33 is fitted onto the outer wall of the inner cylinder 31. The inner cylinder 31 serves as the core storage and delivery carrier for the adhesive, rotating synchronously with the connecting shafts 21. The adhesive flows from the inner cylinder 31 to the sponge layer 33 through the multiple arrays of adhesive dispensing grooves 32, ensuring uniform adhesive output and preventing localized adhesive accumulation or loss. Two sets of semi-cylinders 34 are fitted onto the outer wall of the adhesive dispensing grooves 32, and the two sets of semi-cylinders 34 are joined to form a complete cylinder. Multiple arrays of diamond-shaped holes 35 are formed on the surface of each set of semi-cylinders 34, which contact the insulating paper to complete the adhesive application.

[0022] One set of semi-cylinders 34 has a groove 36 on its side wall, and a magnetic strip 37 is fixedly connected inside the groove 36. Another set of semi-cylinders 34 has a protrusion 38 fixedly connected to its side wall. The protrusion 38 is inserted into the groove 36 and magnetically connected to the magnetic strip 37. By inserting the protrusion 38 into the groove 36 and magnetically attracting it to the magnetic strip 37, the two sets of semi-cylinders 34 can be quickly assembled and disassembled, facilitating the replacement of the sponge layer 33 or the cleaning of residual glue and the semi-cylinders 34. Positioning holes 39 are provided at the ends of both sets of semi-cylinders 34. The positioning holes 39 cooperate with the positioning pins 44 of the positioning assembly 4 to achieve precise positioning of the semi-cylinders 34 and the inner cylinder 31.

[0023] A positioning assembly 4 is provided on the outer wall of the inner cylinder 31. The positioning assembly 4 includes a fixing ring 41, which is fixedly connected to the inner wall of the inner cylinder 31 and serves as the fixing base for the positioning assembly 4, rotating synchronously with the inner cylinder 31. Multiple arrayed telescopic rods 42 are fixedly connected to the side wall of the fixing ring 41. A collar 43 is fixedly connected to the end of each telescopic rod 42, and a positioning pin 44 is fixedly connected to the side wall of the collar 43. The positioning pin 44 is inserted into the positioning hole 39. The fixing ring 41 and the collar 43 are elastically connected by a spring 45, which is sleeved on the outer wall of the telescopic rod 42. The elastic force of the spring 45 pushes the collar 43 away from the fixing ring 41, providing a continuous clamping force to the positioning pin 44, ensuring that the positioning pin 44 is always tightly engaged in the positioning hole 39. When it is necessary to disassemble the semi-cylinder 34, simply press the collar 43 to compress the spring 45 and shorten the telescopic rod 42 to pull the positioning pin 44 out of the positioning hole 39. The operation is convenient.

[0024] In this invention, during use, the sponge layer 33 is evenly fitted onto the outer wall of the inner cylinder 31. Then, two sets of semi-cylinders 34 are respectively attached to the outer side of the sponge layer 33, with the protrusion 38 of one set of semi-cylinders 34 aligned with the groove 36 of the other set and inserted. The magnetic attraction of the magnetic strip 37 enables the two sets of semi-cylinders 34 to be quickly joined, forming a complete cylindrical structure enclosing the sponge layer 33. During this process, the spring 45 of the positioning component 4 on the outer wall of the inner cylinder 31 is in a naturally extended state. Its elastic force pushes the collar 43 away from the fixing ring 41, causing the positioning pin 44 to extend synchronously and insert precisely into the positioning holes 39 at the ends of the two sets of semi-cylinders 34. With the continuous tightening force of the spring 45, accurate positioning and a stable connection between the semi-cylinders 34, the inner cylinder 31, and the sponge layer 33 are ensured, preventing relative displacement during the adhesive application process.

[0025] The motor 23 is started, and its output shaft drives the connecting shaft 21, which is fixedly connected to it, to rotate. Since the inner cylinder 31 is fixed between the two sets of connecting shafts 21, it rotates synchronously with the connecting shafts 21. Adhesive is continuously supplied into the rotating inner cylinder 31 through the glue delivery pipe 22, which is rotatably connected to the other set of connecting shafts 21. After the adhesive is evenly distributed inside the inner cylinder 31, it slowly penetrates into the outer sponge layer 33 through the glue outlet grooves 32 arrayed on its outer wall, allowing the sponge layer 33 to be evenly saturated with adhesive. As the semi-cylinder 34 rotates, the diamond-shaped holes 35 on its surface continuously contact the surface of the insulating paper. The adhesive absorbed in the sponge layer 33 is evenly transferred to the surface of the insulating paper through the gaps in the diamond-shaped holes 35, completing the adhesive application process.

[0026] When the glue application is completed or the sponge layer 33 needs to be replaced or residual glue needs to be cleaned, turn off the glue supply switch of the motor 23 and the glue supply pipe 22, manually press the collar 43 of the positioning component 4. After the collar 43 is under force, it compresses the spring 45 and drives the telescopic rod 42 to shorten, so that the positioning pin 44 is pulled out from the positioning hole 39 at the end of the semi-cylinder 34, releasing the positioning restriction between the semi-cylinder 34 and the inner cylinder 31. Then, overcome the attraction force of the magnetic strip 37 between the two sets of semi-cylinders 34, pull the protrusion 38 out of the groove 36, and the two sets of semi-cylinders 34 can be separated, so that the sponge layer 33 can be replaced, or the residual glue inside the inner cylinder 31 and the inner wall of the semi-cylinder 34 can be cleaned. The operation is convenient and efficient, which greatly reduces the time cost of equipment maintenance and consumable replacement.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
