Description

Technical Field

[0001] This utility model relates to the field of cushioning pad production technology, specifically a flat-pressure cushioning pad edge sealing machine. Background Technology

[0002] A cushioning pad is a material or product that uses its own elastic deformation to absorb impact and dampen vibration, thereby protecting items from damage. It is widely used in many fields. During the production process of cushioning pads, burrs will appear on the edges after the cushioning pads are cut. In order to ensure the appearance of the cushioning pads, it is usually necessary to use an edge banding machine to band the edges of the cut cushioning pads.

[0003] When using existing flat-pressure edge banding machines, the buffer pad and edge banding material are usually transported together or manually placed in a suitable position. Then, the adhesive is sprayed onto the gap between the buffer pad and the edge banding material. After the adhesive is sprayed, the pressure plate is moved to apply pressure to the buffer pad and the edge banding material in one go. Combined with the adhesive effect of the adhesive, the buffer pad and the edge banding material are tightly bonded together.

[0004] Existing flat-pressure edge banding machines have the following problems: they apply pressure to the cushioning pad and the edge banding material in one go through a pressure plate, resulting in a relatively fixed pressure distribution, excessively long pressurization and holding times, and low pressing efficiency. To address these issues, we propose a flat-pressure cushioning pad edge banding machine. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a flat-pressure type cushioning pad sealing machine. By setting up a pressing mechanism and using pressing rollers for rolling, the adhesive can quickly penetrate into the gap between the cushioning pad and the sealing material under pressure, thereby accelerating the pressing speed and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flat-press type buffer pad sealing machine, including a processing table, an adjustable glue applicator head on the upper surface of the processing table, and a pressing mechanism;

[0007] The pressing mechanism includes a chute, a lead screw, a slider, a rotating rod, a pressing roller, an adjusting component, and a sensing component. A chute is provided on the rear side of the upper surface of the processing table. A lead screw is rotatably connected inside the chute, and a slider is threadedly connected to the outer surface of the lead screw. The slider is slidably connected inside the chute. A rotating rod is rotatably connected to a hole on the upper surface of the slider via the adjusting component. A pressing roller is fixedly sleeved on the upper surface of the rotating rod. A sensing component is provided on the upper surface of the processing table. Through the setting of the pressing mechanism, the pressing roller performs rolling pressure, allowing the adhesive to quickly penetrate into the gaps between the buffer pad and the sealing material under pressure, thereby accelerating the pressing speed.

[0008] Furthermore, it also includes a controller, which is located on the front side of the processing table. The input terminal of the controller is electrically connected to an external power supply to facilitate the normal operation of the equipment.

[0009] Furthermore, a motor is provided on the right side of the upper surface of the processing table. The left end of the output shaft of the motor is fixedly connected to the right end of the lead screw, and the input end of the motor is electrically connected to the output end of the controller to facilitate driving the lead screw to rotate.

[0010] Furthermore, the adjustment assembly includes a gear and a rack. The lower end of the rotating rod passes through the lower surface of the slider and is provided with a gear. The lower surface of the processing table is provided with a rack. The gear and the rack are meshed and connected to facilitate the rotation of the rotating rod while it is moving.

[0011] Furthermore, the sensing component includes a connecting plate, rubber protrusions, a contact sensor, and a photoelectric sensor. Rubber protrusions are provided on both the left and right sides of the slider via the connecting plate. Contact sensors are provided on both the left and right sides of the lower side of the slide groove. The sensing surfaces of the contact sensors are all facing the slider. A photoelectric sensor is provided on the left side of the upper surface of the processing table. The output terminals of the contact sensors and the photoelectric sensors are electrically connected to the input terminals of the controller to facilitate the sensing of the working status.

[0012] Furthermore, the upper surface of the slider is provided with a conveying pipe via a fixed base. The discharge end of the conveying pipe is provided with a glue applicator. A corrugated pipe with steel wire and a glue pump are connected in series on the left and right sides of the conveying pipe, respectively. The input end of the glue pump is electrically connected to the output end of the controller to facilitate the spraying of glue.

[0013] Furthermore, both the left and right sides of the processing table are rotatably connected to conveyor rollers via rotating shafts, and the two conveyor rollers are connected by a conveyor belt. A second motor is provided on the left side of the processing table. The rear end of the output shaft of the second motor is fixedly connected to the front end of the rotating shaft on the left side. The input end of the second motor is electrically connected to the output end of the controller, which facilitates the conveying of cushioning pads and edge sealing materials.

[0014] Furthermore, the upper surface of the processing table is provided with a support frame, and an electric push rod is provided in the mounting groove on the upper surface of the support frame. The lower end of the telescopic shaft of the electric push rod is provided with a movable frame. Limiting rods are provided on both the left and right sides of the upper surface of the movable frame. Sliding holes are opened on both the left and right sides of the upper surface of the support frame. The limiting rods are slidably connected to the inside of the sliding holes on the same side. The movable frame is rotatably connected with evenly distributed pressure rollers. The input end of the electric push rod is electrically connected to the output end of the controller, which facilitates applying downward pressure to the buffer pad to prevent it from shifting during transportation.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This flat-pressure type buffer pad edge sealing machine has the following advantages:

[0016] The rotation of the lead screw drives the slider to move along the groove, and the rotating rod moves accordingly. Under the meshing relationship of the gear and rack, the rotating rod drives the pressing roller to move while the pressing roller rotates around the rotating rod, rolling the buffer pad and the edge sealing material. The movement of the slider drives the rubber protrusion to move through the connecting plate until one of the rubber protrusions contacts the sensing surface of the contact sensor. The working state of motor one changes and the output shaft reverses, causing the pressing roller to move in the opposite direction to roll the buffer pad and the edge sealing material again. During the rolling process, the pressing roller is in rolling contact with the buffer pad and the edge sealing material. The contact area will continuously change and gradually cover the entire edge sealing area, so that the adhesive can quickly penetrate into the gap of the buffer pad and the edge sealing material under pressure, thereby accelerating the pressing speed.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This embodiment provides a technical solution: a flat-press type cushioning pad edge sealing machine, including a processing table 1, the upper surface of which is provided with an adjustable glue applicator 6 (the edge sealing of cushioning pads has problems such as air bubbles, pits, and pinholes. After many attempts, it was found that adjusting the edge sealing glue concentration and increasing the number of edge sealing times can improve the edge sealing uniformity and smoothness. Specifically, the edge sealing glue concentration ratio is changed from 1:2 to 1:4, and the number of edge sealing times is changed from 2 to 3). It also includes a pressing mechanism 3 and a controller 2, which is set on the processing table 1. On the front side, the input end of the controller 2 is electrically connected to an external power source. The upper surface of the slider 33 is provided with a conveying pipe 7 via a fixed base 5. A glue applicator 6 is provided at the outlet end of the conveying pipe 7. A corrugated steel wire pipe 8 and a glue pump 9 are connected in series on the left and right sides of the conveying pipe 7, respectively. The input end of the glue pump 9 is electrically connected to the output end of the controller 2. Conveying rollers 11 are rotatably connected to the left and right sides of the interior of the processing table 1 via rotating shafts 10. The two conveying rollers 11 are connected by a conveyor belt 12. A second motor 13 is located on the left side of the interior of the processing table 1. The rear end of the output shaft of motor 3 is fixedly connected to the front end of the rotating shaft 10 on the left. The input end of motor 2 13 is electrically connected to the output end of controller 2. The upper surface of the processing table 1 is provided with a support frame 14. An electric push rod 15 is provided in the mounting groove on the upper surface of the support frame 14. The lower end of the telescopic shaft of the electric push rod 15 is provided with a movable frame 16. Limiting rods 17 are provided on both the left and right sides of the upper surface of the movable frame 16. Sliding holes 18 are opened on both the left and right sides of the upper surface of the support frame 14. The limiting rods 17 are slidably connected to the inside of the sliding holes 18 on the same side. (Electric push rod 1) The core bearing design of 5 is axial force, and its ability to withstand radial force is weak. The limiting rod 17 and the sliding hole 18 guide and limit the movable frame 16 to form a radial positioning frame independent of the electric push rod 15. The radial force generated by the movable frame 16 during movement is preferentially borne by the limiting rod 17 and the sliding hole 18, so that the electric push rod 15 only needs to bear the axial force, reducing the damage to the electric push rod 15. The movable frame 16 is rotatably connected with uniformly distributed pressure rollers 19. The input end of the electric push rod 15 is electrically connected to the output end of the controller 2.

[0025] With this setup, the feed end of the conveying pipe 7 is connected to an external device that supplies adhesive. The buffer pad and sealing material are placed on the right side of the upper surface of the processing table 1. Under the control of the controller 2, the electric push rod 15 operates. Under the restriction of the limit rod 17 and the sliding hole 18, the telescopic shaft of the electric push rod 15 drives the support frame 14 to move downward, causing the lower side of the outer surface of the pressure roller 19 to contact the upper surface of the buffer pad. Then, the second motor 13 operates. The output shaft of the second motor 13 drives the left conveyor roller 11 to rotate through the left rotating shaft 10. The rotation of the conveyor roller 11 causes the conveyor belt 12 to rotate, moving the buffer pad and sealing material from the right... The material is conveyed to the left. When the photoelectric sensor 374 detects the buffer pad, motor 2 13 stops working. At this time, the glue pump 9 starts working and pumps the glue through the conveying pipe 7 to the glue application head 6, spraying the glue onto the gap between the buffer pad and the sealing material. When the controller 2 receives a signal from the first contact sensor 373, the glue pump 9 stops working. After the controller 2 receives two signals from the contact sensor 373, motor 1 4 stops working and motor 2 13 starts working, conveying the sealed buffer pad to the left through the conveyor belt 12. Then, the staff puts the buffer pad into the external cooling equipment to cool the glue quickly.

[0026] The pressing mechanism 3 includes a slide groove 31, a lead screw 32, a slider 33, a rotating rod 34, a pressing roller 35, an adjusting assembly 36, and a sensing assembly 37. A slide groove 31 is provided on the rear side of the upper surface of the processing table 1. The lead screw 32 is rotatably connected inside the slide groove 31, and the slider 33 is threadedly connected to the outer surface of the lead screw 32. (The exposed portion of the outer surface of the lead screw 32 is fitted with a bellows, which are fixedly connected between the left side of the slider 33 and the left wall of the slide groove 31, and between the right side of the slider 33 and the right wall of the slide groove 31. The bellows always keep the lead screw...) 32 is wrapped and shielded to prevent the external environment from affecting the threaded transmission of the lead screw 32 and the slider 33. The slider 33 is slidably connected to the inside of the slide groove 31. A rotating rod 34 is rotatably connected to the rotating hole opened on the upper surface of the slider 33 through the adjusting component 36. A pressing roller 35 is fixedly sleeved on the upper side of the outer surface of the rotating rod 34. A sensing component 37 is provided on the upper surface of the processing table 1. A motor 4 is provided on the right side of the upper surface of the processing table 1. The left end of the output shaft of the motor 4 is fixedly connected to the right end of the lead screw 32. The input end of the motor 4 is electrically connected to the output end of the controller 2.

[0027] The adjusting component 36 includes a gear 361 and a rack 362. The lower end of the rotating rod 34 passes through the lower surface of the slider 33 and is equipped with a gear 361. The lower surface of the processing table 1 is equipped with a rack 362. The gear 361 and the rack 362 are meshed together. (A protective cover is bolted to the lower surface of the processing table 1, which encloses the gear 361 and the rack 362 to prevent external environmental factors from affecting the meshing connection between the gear 361 and the rack 362.) The sensing component 37 includes a connecting plate 371, a rubber protrusion 372, a contact sensor 373, and a photoelectric sensor 374. Rubber protrusions 372 are provided on both the left and right sides of the slider 33 through the connecting plate 371. Contact sensors 373 are provided on both the left and right sides of the lower side of the slide groove 31. The sensing surfaces of the contact sensors 373 all face the slider 33. On one side, (the contact sensor 373 can be a piezoelectric contact sensor. Based on the positive piezoelectric effect, when the piezoelectric material on the sensing surface is subjected to external mechanical force, its internal lattice deforms, resulting in the generation of equal and opposite charges on the surface (the charges also disappear after the mechanical force disappears). At this time, the contact sensor 373 sends a signal to the controller 2). On the left side of the upper surface of the processing table 1, there is a photoelectric sensor 374. (The photoelectric sensor 374 is a diffuse reflection type photoelectric switch. The detection head of the photoelectric sensor 374 contains a light emitter and a light receiver. When the buffer pad passes by, it blocks the light and reflects the light back. The light receiver receives the light signal and transmits it to the controller 2). The output terminals of the contact sensor 373 and the photoelectric sensor 374 are respectively electrically connected to the input terminal of the controller 2.

[0028] With this setup, motor 4 operates, and its output shaft drives the lead screw 32 to rotate. The rotation of the lead screw 32 causes the threaded slider 33 to move along the slide groove 31 from right to left. (At this time, the applicator head 6 moves with the slider 33, completing the adhesive spraying operation. Due to the presence of the corrugated steel wire tube 8, when the applicator head 6 moves away from the adhesive pump 9, the corrugated steel wire tube 8 extends; when the applicator head 6 moves closer to the adhesive pump 9, the corrugated steel wire tube 8 contracts, preventing pipe tangling and ensuring stable adhesive spraying during movement.) The rotating rod 34 moves accordingly. The presence of rack 362 means that, under the meshing relationship between gear 361 and rack 362, rotating rod 34 drives pressing roller 35 to move from right to left. Simultaneously, pressing roller 35 rotates around rotating rod 34 to roll the buffer pad and sealing material. The movement of slider 33 drives rubber protrusion 372 to move through connecting plate 371 until one side of rubber protrusion 372 contacts the sensing surface of contact sensor 373. Contact sensor 373 transmits a signal to controller 2, changing the working state of motor 4 and reversing the output shaft, causing pressing roller 35 to move from left to right to roll the buffer pad and sealing material again.

[0029] The working principle of the flat-pressure cushion sealing machine provided by this utility model is as follows: The feed end of the conveying pipe 7 is connected to the equipment that provides the adhesive. The cushion and sealing material are placed on the right side of the upper surface of the processing table 1. Under the control of the controller 2, the electric push rod 15 works. Under the restriction of the limit rod 17 and the sliding hole 18, the telescopic shaft of the electric push rod 15 drives the support frame 14 to move downward, so that the lower side of the outer surface of the pressure roller 19 contacts the upper surface of the cushion. Then the second motor 13 works. The output shaft of the second motor 13 drives the left conveyor roller 11 to rotate through the left rotating shaft 10. The rotation of the conveyor roller 11 causes the conveyor belt to rotate. Motor 12 rotates, conveying the cushioning pad and sealing material from right to left. When the photoelectric sensor 374 detects the cushioning pad, motor 13 stops working. At this time, the glue pump 9 works, pumping the glue through the delivery pipe 7 to the glue application head 6, spraying the glue onto the gap between the cushioning pad and the sealing material. Simultaneously, motor 4 works, and the output shaft of motor 4 drives the lead screw 32 to rotate. The rotation of the lead screw 32 drives the threaded slider 33 to move along the slide groove 31 from right to left. (At this time, the glue application head 6 moves with the slider 33, completing the glue spraying work. Due to the presence of the steel wire corrugated pipe 8, the glue application head 6 moves away from the glue pump 9.) During operation, the corrugated steel tube 8 extends, and as the applicator head 6 moves closer to the glue pump 9, the corrugated steel tube 8 contracts to prevent pipe tangling and ensure stable glue spraying during the movement of the applicator head 6. The rotating rod 34 moves accordingly. Due to the presence of the rack 362, the meshing relationship between the gear 361 and the rack 362 causes the rotating rod 34 to drive the pressing roller 35 to move from right to left. Simultaneously, the pressing roller 35 rotates around the rotating rod 34, rolling the buffer pad and sealing material. The movement of the slider 33, via the connecting plate 371, drives the rubber protrusion 372 to move until it reaches one side. Rubber protrusion 372 contacts the sensing surface of contact sensor 373. Contact sensor 373 transmits a signal to controller 2, and the working state of motor 4 changes, the output shaft reverses, causing the pressing roller 35 to move from left to right to roll the buffer pad and sealing material again. When controller 2 receives a signal from contact sensor 373 once, glue pump 9 stops working. After controller 2 receives two signals from contact sensor 373, motor 4 stops working, and motor 13 starts working, transporting the sealed buffer pad to the left through conveyor belt 12. Then, the worker puts the buffer pad into the external cooling equipment to cool the glue quickly.

[0030] It is worth noting that the controller 2 disclosed in the above embodiments can be an STM32 series, the contact sensor 373 can be a SAYL101Y, the photoelectric sensor 374 can be an E3ZG series, the motor 4 and the motor 13 can be YP-100 series, the glue pump 9 can be an NCB series rotor pump, and the controller 2 controls the operation of the contact sensor 373, the photoelectric sensor 374, the motor 4, the glue pump 9, the motor 13, and the electric push rod 15 using methods commonly used in the prior art.
