Description

Technical Field

[0001] The present invention relates to the technical field of plate conveying, and more particularly to a plate turning device for an automatic floor silent pad laminating machine. Background Art

[0002] Automatic floor mats are specially designed floor coverings that reduce noise and echo while providing a comfortable walking experience. Currently, during the production process of automatic floor mats, specialized laminating machines are typically used to automatically adhere the mats to the floor surface. However, when producing double-sided floor mats, a specialized flap device is required to complete the gluing process on one side of the floor and then flip the floor over to facilitate subsequent gluing on the other side.

[0003] In the prior art, for example, publication number CN111791572A discloses an automatic laminating production line and method for PVC composite floor silent pads, which belongs to the category of automated production equipment for panels. It includes an automatic feeding device, a UV curing machine, a continuous flipping machine, a gluing machine, a conveying device, an automatic laminating machine for large-plate silent pads, an automatic cutting machine, a punching and feeding device, a punching device, a reversing conveying device, a small-plate flipping machine, an automatic stacking machine, and a double-station stacking machine, which are connected in sequence. Among them, the small flipping machine is used to flip the panels. Another example is publication number CN215827767U, which discloses a flipping device for an automatic floor silent pad laminating machine, comprising two groups of support plates, a flipping plate fixedly sleeved on the outer side of the first connecting shaft, cavities respectively provided in the left and right ends of the flipping plate, a snap-in block snapped in the snap-in groove, and a second spring respectively provided in the two groups of the slide grooves. It solves the problem of panels falling during the flipping process.

[0004] However, in the processing of automatic silent pad flooring, when the glued flooring is rolled, some glue will be squeezed out and concentrated on the sides of the flooring. When the above-mentioned two flip-up devices are used to flip the flooring, the clamping ends thereof will contact the sides of the flooring. Since the squeezed glue has not completely dried, the glue will be adsorbed on the clamping ends of the flip-up device. If the amount of glue is large, it may not only make it difficult for the flooring to be separated from the flip-up device, but it will also need to be manually separated later, thereby increasing the workload of the staff and causing secondary pollution to the subsequent flooring. Moreover, in the process of flipping the flooring, the glue will continue to spread to the outside of the side panel, which may affect the bonding operation on the other side of the flooring.

DETAILED DESCRIPTION

[0038] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0039] Please refer to Figures 1 to 2A flip device for an automatic floor silent pad laminating machine includes: a frame 1 and a flip mechanism 3. The frame 1 is located between two plate conveyors. The plate enters the loading end of the flip device from the conveyor at one end. After being flipped by the flip device, the plate is transported by the conveyor at the other end. The flip mechanism 3 is arranged on the frame 1, and the flip mechanism 3 includes a clamping part 31, a driving part 32 and a blowing dryer 33; wherein the clamping part 31 is used to clamp and fix the top and bottom surfaces of the floor 2; the driving part 32 is connected to the clamping part 31, which is used to drive the clamping part 31 to flip along the conveying direction of the floor 2, and simultaneously make the clamping end of the clamping part 31 drive the floor 2 to rotate; and the blowing dryer 33 is connected to the driving part 32 and the clamping part 31 respectively, which is used to blow dry the glue overflowed from the side of the floor 2, and the blowing dryer 33 has two use states: retracted and expanded. When the blowing dryer 33 is in the retracted state, after the floor 2 enters the clamping end of the clamping part 31, one side of the floor 2 contacts with the blowing dryer 33 and is in a preset clamped posture, and When the clamping part 31 clamps the floor 2 in a preset clamped posture, the clamping part 31 synchronously drives the blowing trunk 33 to move to the expanded state, so that the blowing trunk 33 is away from the floor 2 and the air outlet end is directed toward the glue bonding part of the floor 2. When the driving part 32 drives the clamping part 31 and the floor 2 to rotate, the blowing trunk 33 is synchronously driven to perform reciprocating linear motion, so that the blowing trunk 33 follows the rotation posture of the floor 2 and adapts to the changes synchronously, maintaining the same distance between the air outlet end of the blowing trunk 33 and the side of the floor 2, and maintaining a stable effect on the drying of the glue. It can avoid the problem of excessive blowing of the glue by the blowing trunk 33 or insufficient drying wind force. If the blowing is excessive, the glue will spread to other parts of the floor 2. If the drying separation is insufficient, the glue will still adhere to its structure.

[0040] For details, please refer to Figures 3 and 4There are two clamping parts 31, and the two clamping parts 31 are spaced one hundred and eighty degrees apart. When one clamping part 31 clamps the floor 2, the other clamping part 31 just completes the flipping action of the floor 2, which can speed up the flipping speed of the floor 2; the clamping part 31 includes a flipping arm 311, an upper clamp and a lower clamp, the flipping arm 311 is connected to the driving end of the driving part 32, the upper clamp and the lower clamp are rotatably installed on the upper and lower ends of the flipping arm 311 respectively, the upper clamp has a vertical telescopic function, and the top surface of the lower clamp is flush with the bottom surface of the floor 2. When clamping the floor 2, the upper clamp extends downward and contacts the top surface of the floor 2, and finally the floor 2 is fixed between the upper clamp and the lower clamp. The upper clamp includes a telescopic drive source 312, a rotating shaft sleeve 313, a connecting slide 314 and an upper clamping plate 315. The telescopic drive source 312 is fixed to the top of the flip arm 311, and its telescopic end is rotatably connected to the top of the connecting slide 314. The telescopic drive source 312 can be a cylinder, which is extended and retracted by an external control system controller. The bottom end of the connecting slide 314 passes through the top of the flip arm 311 downward and is fixedly connected to the top of the upper clamping plate 315. The rotating shaft sleeve 313 is rotatably installed on the outside of the connecting slide 314, and its inner side is connected to the upper clamping plate 315. The outer side of the connecting slide rod 314 is slidably connected, and an arc-shaped recess is provided on the outer side of the connecting slide rod 314, and an arc-shaped protrusion is provided on the outer side of the rotating sleeve 313 to match the arc-shaped protrusion. The arc-shaped protrusion and the arc-shaped recess cooperate and slide, so that the connecting slide rod 314 can slide up and down along the inner side of the rotating sleeve 313, and can also rotate with the rotating sleeve 313; the lower clamp includes a lower clamping plate 316, and the lower clamping plate 316 is rotatably installed at the bottom of the flip arm 311, and the lower clamping plate 316 and the upper clamping plate 315 maintain upper and lower symmetry.

[0041] It should be noted that when the above-mentioned clamping portion 31 is used to clamp and fix the floor 2, the floor 2 is driven by the conveyor to gradually move to the top surface of the lower clamping plate 316. When one side of the floor 2 contacts one end of the blowing stem 33 in a retracted state, since the contact position of the blowing stem 33 with the floor 2 is the lower end position of the floor 2, it is possible to avoid the overflowing glue from contacting the blowing stem 33. If the posture of the floor 2 is slightly offset during the previous conveying process, after contacting the blowing stem 33, it is resisted by the floor 2 and cannot continue to move. Under the continued driving action of the conveyor, the posture of the floor 2 can be corrected, thereby achieving the purpose of correcting the posture of the floor 2. After the floor 2 reaches the preset position, it begins to clamp and fix it. By extending the telescopic driving source 312, the connecting slide 314 can be driven to extend downward, and the lower clamping plate 316 follows the connecting slide 314 to approach the floor 2. After the bottom surface of the lower clamping plate contacts the top surface of the floor 2, the floor 2 is clamped between the lower clamping plate 316 and the upper clamping plate 315, and the clamping action is completed; the clamping part 31 provided in the present invention mainly clamps and fixes the top and bottom surfaces of the floor 2, and has no contact with the side of the floor 2, thereby preventing the glue overflowing from the side of the floor 2 from being adsorbed on the clamping part 31, solving the problem that the floor 2 is difficult to detach due to excessive glue adsorbed on the clamping part 31.

[0042] Please refer to Figures 4 and 5 Although the clamping portion 31 may not contact the side of the floor 2, during the flipping process, the glue that has not yet dried will continue to flow and spread to the side of the floor 2, which will not only contaminate other positions of the floor 2, but may also flow to the other side of the floor 2, thereby affecting the bonding operation on the other side. Therefore, in order to solve this problem, the present invention further provides a blowing trunk 33, specifically: the blowing trunk 33 includes a reciprocating drive assembly 333, two drying nozzle assemblies 331 and two support assemblies 332, the two drying nozzle assemblies 331 It is hinged with the two support assemblies 332, and the support assembly 332 is connected to the movable end of the top surface of the upper clamping plate 315. When the upper clamp extends downward to clamp the floor 2, the support assembly 332 drives the drying nozzle assembly 331 to move away from the side of the floor 2, and the drying nozzle assembly 331 switches to the preset drying posture during the contraction process; the reciprocating drive assembly 333 is connected to the rotating shaft sleeve 313, and when the clamping part 31 follows the driving part 32 to flip, the reciprocating drive assembly 333 synchronously drives the connecting slide rod 314 to rotate.

[0043] For details, please refer to Figures 5 to 8The supporting assembly 332 includes a connecting driving member and a movable supporting member, the connecting driving member includes a connecting plate 3321 and an extrusion plate 3322, the top surface of the upper clamping disk 315 is provided with a circular groove 3323, one end of the connecting plate 3321 is slidably connected to the circular groove 3323, and the other end is slidably connected to the extrusion plate 3322; the movable supporting member includes a slide seat 3324 and a fixed seat 3325, the fixed seat 3325 is connected to the reciprocating driving assembly 333, the slide seat 3324 is slidably connected to the fixed seat 3325, a return spring 3326 is fixedly installed between the slide 3324 and the fixed seat 3325, the top of the slide seat 3324 is provided with a through inclined groove 3327, the bottom end of the extrusion plate 3322 is provided with an inclined surface adapted to the inclined groove 3327, the lower end of the extrusion plate 3322 is slidably connected to the upper end of the fixed seat 3325, and its bottom is slidably connected to the inclined groove 3327.

[0044] The drying nozzle assembly 331 includes a drying nozzle 3311, a transmission gear 3312, a torsion spring 3313, a connecting shaft 3314, a matching tooth groove 3315 and a positioning groove 3316. Two drying nozzles 3311 are provided, and the two drying nozzles 3311 are symmetrically distributed. The ends thereof are connected to the external air dryer through a flexible tube. The transmission gear 3312 is rotatably mounted on one side of the slide 3324. The drying nozzle 3311 is located at the end of the slide 3324, and one side thereof is connected to the rotating end of the transmission gear 3312 through a rotating shaft. The torsion spring 3313 is sleeved on the rotating shaft. On the outside of the shaft, its two ends are respectively fixed to the blow-drying nozzle 3311 and the slide 3324, and the matching tooth groove 3315 is opened on one side of the fixed seat 3325, and the positioning groove 3316 is opened on the inner side of the slide 3324. One end of the connecting shaft 3314 is fixed to the outside of the blow-drying nozzle 3311, and the other end is rotatably connected to the inner wall of the positioning groove 3316. Through the coordinated arrangement of the positioning shaft and the positioning groove 3316, the rotation direction of the blow-drying nozzle 3311 can be restricted so that it can only rotate in the counterclockwise direction and will not rotate when squeezed by the floor 2. The reciprocating drive assembly 333 includes a driving body 3331, a first bevel gear 3332, a second bevel gear 3333, and a swinging lever 3334. The driving body 3331 is slidably mounted on the bottom of the flip arm 311. The first bevel gear 3332 is connected to the driving end of the driving unit 32. The second bevel gear 3333 is rotatably mounted on the top of the flip arm 311, one side of which meshes with the first bevel gear 3332. One end of the swinging lever 3334 is rotatably connected to the bottom of the second bevel gear 3333, and the other end is rotatably connected to the top of the driving body 3331. One end of the driving body 3331 is fixedly connected to the fixed base 3325. In addition, a roller 3328 is rotatably mounted on the bottom of the connecting plate 3321. After the bottom surface of the lower clamping plate 316 contacts the floor 2, the bottom surface of the roller 3328 contacts the top plate of the floor 2.

[0045] It should be noted that when the above-mentioned blowing dryer 33 is in use and is in a retracted posture, the floor 2 is gradually moved to the top surface of the lower clamping plate 316 under the driving action of the conveyor, and after the side of the floor 2 contacts the two drying nozzles 3311 at the same time, the floor 2 is in a preset standard posture. Afterwards, during the process of the clamping portion 31 clamping and fixing the floor 2, the telescopic driving source 312 extends downward, which can drive the upper clamping plate 315 to move downward, and can cause the connecting plate 3321 and the squeezing plate 3322 to move downward together. When the squeezing plate 3322 moves downward, its bottom gradually extends into the inclined groove 3327, thereby generating a horizontal squeezing force on the slide 3324, which can drive the slide 3324 to slide on the fixed seat 3325 and gradually move away from the floor 2. The return spring 3326 is squeezed by the slide 3324 and contracts synchronously, and the drying nozzle 33 When the gear 3312 is engaged with the tooth groove 3315, the sliding seat 3324 will continue to slide, so that the gear 3312 can rotate along the tooth groove 3315, thereby driving the port of the drying nozzle 3311 to rotate downward. After the lower clamping plate 316 is in close contact with the top surface of the floor 2, the telescopic driving source 312 no longer moves downward, the connecting plate 3321 and the extruding plate 3322 stop moving, the sliding seat 3324 and the drying nozzle 3311 do not move, and the port of the drying nozzle 3311 rotates toward the side of the floor 2. At this time, the drying portion 33 is in the expanded state. After that, the external air dryer is started by controlling the two drying nozzles 3311 to blow air to the side of the floor 2, thereby accelerating the drying of the glue.

[0046] When the driving part 32 drives the clamping part 31 and the floor 2 to rotate, the first bevel gear 3332 follows the driving part 32 to rotate, which can drive the second bevel gear 3333 to rotate. After the second bevel gear 3333 rotates, it can drive the swing rod 3334 to move, so that it generates a horizontal reciprocating driving force for the driving body 3331, thereby causing the driving body 3331 to reciprocate horizontally along the flip arm 311. Since the connecting plate 3321 is slidably connected to the annular groove 3323 of the upper clamping plate 315, the upper clamping plate 315 rotates, and the connecting plate 3321 does not hinder its rotation. When the driving body 3331 moves back and forth, it can drive the squeezing plate 3322, the fixing seat 3325, the sliding seat 3324 and the drying nozzle 3311 to perform reciprocating action together. Since the side of the floor 2 is gradually shortened from the distance between it and the drying nozzle 3311 during rotation, the drying nozzle 3311 moves synchronously away from the side of the floor 2. , so that the distance between the two is maintained within a preset range. When the other side of the floor 2 rotates toward the drying nozzle 3311, the distance between the side and the drying nozzle 3311 gradually increases. At this time, the drying nozzle 3311 just follows the driving body 3331 to move synchronously close to the floor 2, and repeats this action until the clamping part 31 drives the floor 2 to rotate together for one circle. The drying nozzle 3311 evenly dries the glue overflowing from the side of the floor 2, and the uniform rolling pressure of the roller 3328 on the top surface of the floor 2 during the rotation process can promote the uniform flow and diffusion of glue between the floor 2 and the automatic silent pad, and the driving part 32 also just drives the clamping part 31 and the floor 2 to flip one hundred and eighty degrees. After that, the telescopic driving source 312 begins to contract and drives the upper clamping plate 315 to move upward and separate from the floor 2. After that, under the driving action of the conveyor, the flipped floor 2 can be separated from the clamping part 31, and the flipping action is completed.

[0047] It can be seen from this that the blowing stem 33 provided in the present invention can not only quickly dry the glue overflowing from the side of the floor 2, but also, by cooperating with the clamping portion 31, can synchronously realize the switching of its use state when the clamping portion 31 clamps the floor 2, so that the contracted state of the blowing stem 33 used as a positioning structure can be adaptively switched to a drying state adapted to the floor 2; in addition, the blowing stem 33 can be used in conjunction with the driving portion 32 to enable the drying nozzle 3311 to synchronously adapt to the rotation posture of the floor 2 during the rotation of the floor 2, so that the distance between the drying nozzle 3311 and the side of the floor 2 is maintained within a preset range, thereby achieving precise blowing of the glue on the side of the floor 2 to achieve an effective drying effect.

[0048] Please refer to Figures 9 and 10The driving part 32 includes a flipping drive assembly 321 and two rotating drive assemblies 322. The flipping drive assembly 321 is connected to the flip arm 311 and is used to drive the flip arm 311 to flip. The two rotating drive assemblies 322 are correspondingly connected to the two upper clamps and are used to drive the upper clamps to rotate. The rotating drive assembly 322 includes a supporting sleeve 3221, an incomplete gear ring 3222, a matching gear 3223, a rotating rod 3224, a third bevel gear 3225, two fourth bevel gears 3226 and two fifth bevel gears 3227. The supporting sleeve 3221 is fixedly mounted on the inner side of the frame 1, the incomplete gear ring 3222 is fixedly mounted on the end of the supporting sleeve 3221, and the matching gear 3223 is rotatably mounted on one side of the flip arm 311. Its outer side is meshed with the incomplete gear ring 3222, rotating. The rod 3224 is rotatably mounted on one side of the flip arm 311, and the two fifth bevel gears 3227 are respectively fixed to the end of the rotating rod 3224 and one side of the matching gear 3223, and the two fifth bevel gears 3227 are meshed with each other. The third bevel gear 3225 is fixedly sleeved on the outside of the rotating rod 3224, and its bottom is meshed with the second bevel gear 3333. The two fourth bevel gears 3226 are respectively fixed to the rotating shaft sleeve 313 and the end of the rotating rod 3224, and the two fourth bevel gears 3226 are meshed with each other. The flipping drive assembly 321 includes a driving motor 3211 and a driving roller 3212. The support sleeve 3221 is sleeved on the outside of the driving roller 3212, and the center of the driving roller 3212 coincides with the center of the support sleeve 3221. One end of the flipping arm 311 is fixedly sleeved on the outside of the driving roller 3212. The driving motor 3211 is fixed to the outside of the frame 1. The driving roller 3212 is rotatably installed on the inside of the frame 1. The rotating end of the driving motor 3211 is fixed to one end of the driving roller 3212.

[0049] The second gear 3208 of the second end is rotated by the second end gear 3210, and the second end gear 3211 of the second end gear 3212 is rotated by the second end gear 3211, so that the second end gear 3210 of the second end gear 3212 can be rotated. The centrifugal force generated can make the glue spread evenly around, making its distribution more uniform, so as to improve its bonding effect; and when the floor 2 is about to flip one hundred and eighty degrees, the cooperating gear 3223 separates from the incomplete gear ring 3222. At this time, the floor 2 has just rotated one circle and no longer rotates. After that, the floor 2 flips over to contact the conveyor, and the entire flipping action is completed; and the driving part 32 provided in the present invention is not only used to drive the clamping part 31 and the floor 2 to complete the 180-degree flipping action together, but also to be adapted for use with the clamping part 31 and the blowing dryer 33 to realize the rotation and drying functions of the floor 2. In addition, by adopting this driving method, the rotation function and the flipping action of the floor 2 can be synchronized, and the rotation function can be adaptively started and ended. There is no need to set up multiple drive sources for separate driving, nor is there a need to set up a control program for control. The layout of the responsible drive and control units is simplified, while reducing the cost of use and being able to well match the dynamic changes of the floor 2.

[0050] The above describes an embodiment of this specific implementation method, but this embodiment is not limited to the above specific implementation method. The above specific implementation method is merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
