Description

Technical Field

[0001] This invention relates to the field of emergency blanket processing equipment technology, and in particular to an automatic emergency blanket processing machine. Background Technology

[0002] Emergency blankets, also known as sun protection blankets or cold protection blankets, are generally made of tin foil or aluminum foil. They come in three types: double-sided gold, double-sided silver, and gold and silver. They have the functions of keeping warm, protecting against the cold, and sun protection.

[0003] Emergency blankets have good reflective properties and are often carried as emergency equipment during outdoor activities and travel. They are also widely used to keep the injured warm during disasters. Due to their many advantages and their small size and portability when folded, emergency blankets have been widely used since their invention.

[0004] Traditional emergency blanket processing typically involves manual folding and cutting. With advancements in production technology, automated emergency blanket processing has become the current development trend. However, due to the thin and easily torn nature of emergency blankets, automated production processes cannot achieve rapid folding. Manual folding is still required, followed by subsequent processing using a pressing device.

[0005] Considering that emergency blankets are relatively thin and light, they can be absorbed by wind power. By combining the characteristics of emergency blankets, the overall processing steps of emergency blankets can be automated and integrated, thereby achieving better automated processing of emergency blankets.

[0059] The folding device 2 includes a back plate 21, an air chamber 22, and a folding plate 23. The back plate 21 is fixed to the vertical frame 12. The air chamber 22 is located on the front side of the back plate 21. The folding plate 23 is located on the front side of the air chamber 22. The folding plate 23 is a W-shaped plate that is wider at the bottom and narrower at the top. Ventilation holes are evenly distributed on the folding plate 23 and are connected to the air chamber 22. A negative pressure pipe 24 is located on the rear side of the back plate 21. The negative pressure pipe 24 is connected to the air chamber 22 and is connected to the fan 25 through a pipe. The fan 25 is located on the base frame 11. Through the special structure of the folding plate 23, and with the continuous air extraction of the fan 25, the air chamber 22 is kept in a negative pressure state. External control is continuously extracted from the ventilation holes of the folding plate 23, so that the front side of the folding plate 23 is in a negative pressure state. This allows the emergency blanket to be completely attached to the folding plate 23 and bend along the W-shaped groove structure on the folding plate 23.

[0060] The pressing device 3 is located above the vertical frame 12. The pressing device 3 includes a pressing frame 31 and pressing rollers 4. The pressing rollers 4 are located on the pressing frame 31 and are driven by the pressing motor 43. The pressing rollers 4 act on the emergency blanket to provide the moving force for the emergency blanket, thereby ensuring that the raw materials of the emergency blanket move smoothly in the device and realize the processing of the emergency blanket.

[0061] Mounting plate 5, slitting device 6, folding device 7, and palletizing conveyor 8; Mounting plate 5 serves as the main load-bearing structure of the entire device and is used to fix and install various components of the device; Slitting device 6 is used to slit the first aid blankets into sections, and the slit first aid blankets are folded by folding device 7 and stacked and shaped by palletizing conveyor 8 to complete the production and processing of the first aid blankets.

Under the control of the control host 9, the slitting motor 62 drives the slitting roller 61 to rotate according to the preset size specifications, and the cutter 63 completes the segmented cutting of the horizontally folded emergency blanket.

[0063] The folding device 7 includes a folding roller 71 and a folding motor 72. The folding roller 71 is located on the front side of the mounting plate 5, and the folding motor 72 is located on the rear side of the mounting plate 5. The folding motor 72 drives the folding roller 71 through a folding shaft 73. A limiting ring 74 with a single-sided opening C-shaped structure is fitted onto the front end of the folding shaft 73. Folding heads 75 and clamping heads 76 are arranged sequentially on the folding roller 71 at 90° intervals. The clamping heads 76 are connected to the folding roller 71 through a folding connecting rod 77. A drive rod 78 is arranged on the folding connecting rod 77, and a drive disk 79 is arranged at the upper end of the drive rod 78. The drive disk 79 contacts the limiting ring 74. The drive rod 78 is connected to the folding roller 71 through a spring. Next, when folding the emergency blanket, the pre-folded emergency blanket is vertically inserted into the middle position of the folding roller 71. The folding heads 75 and clamping heads 76 of the folding rollers 71 on both sides are 90° apart. The emergency blanket is inserted between the clamping head 76 and the folding roller 71 by the folding head 75. At the same time, the emergency blanket is clamped and folded under the tension of the tension spring. As the folding roller 71 rotates, the drive disc 79 and the limiting ring 74 contact the drive rod 78, which drives the folding rod 77 to move. The folding head 75 releases the edge of the folded and pressed emergency blanket. The folding roller 71 of the folding device 7 repeats the above steps to complete the left and right folds in sequence, thus completing the folding operation of the emergency blanket.

[0064] The palletizing conveyor 8 includes a conveyor belt 81 and a conveyor motor 82. The conveyor belt 81 is mounted on the front side of the mounting plate 5 via a belt shaft, and the conveyor motor 82 is mounted on the rear side of the mounting plate 5. The conveyor motor 82 drives the conveyor belt 81 via the drive belt shaft. A separator plate 83 is mounted on the conveyor belt 81. The first aid blankets that have been segmented and longitudinally folded fall one by one onto the conveyor belt 81 and are separated into individual stacks by the separator plate 83. After a single stack is completed, the conveyor motor 82 drives the conveyor belt 81 to complete the conveying of the first aid blankets to the next packaging unit for further processing.

[0065] The control host 9 is installed on the mounting plate 5. The control host 9 is electrically connected to the cutting motor 62, the folding motor 72 and the conveying motor 82. The operation of the entire device is controlled by the control host 9. The operator can preset relevant parameters to control the entire device.

[0066] The feeding arm 141 is driven by the feeding cylinder 142, which is connected to both the feeding arm 141 and the base frame 11. A support plate 143 is mounted on the base frame 11, with a limit buckle 144 at the front end. A material roller 146 is placed on the support plate 143. A limit groove 147 is provided at the end of the material roller 146, and an adjusting rod 148 is contacted within the limit groove 147. The adjusting rod 148 is slidably connected to an adjusting seat 149 via a screw, and the adjusting seat 149 is fixed to the side of the support plate 143. A rotating bearing 145 is provided on the side of the support plate 143 corresponding to the position of the limit buckle 144. A feeding belt 160 is mounted on the base frame 11, driven by a belt cylinder 161. The tension roller 150 and the feeding belt 160 are synchronously driven by the feeding motor 142 via belts.

[0067] A support rod 26 is provided on the base frame 11. Multiple folding wheels 27 are provided on the support rod 26 corresponding to the W-shaped groove of the folding plate 23. The folding wheels 27 are provided corresponding to the folding plate 23, which can help to fold the emergency blanket and ensure the effect and folding quality.

[0068] The pressing rollers 4 include a fixed roller 41 and an adjusting roller 42. The fixed roller 41 is driven by a pressing motor 43. The adjusting roller 42 is slidably mounted on an adjusting frame 44, which is mounted on a pressing frame 31. An adjusting cylinder 45 is mounted on the side of the adjusting frame 44. The adjusting cylinder 45 drives the adjusting roller 42 to move, thereby achieving the function of adjustable gap between the pressing rollers 4. By driving the adjusting roller 42 to move, the gap between the fixed roller 41 and the adjusting roller 42 can be adjusted, which is suitable for pressing emergency blankets of different thicknesses.

[0069] Multiple sets of tightening rollers 46 are provided on the pressing frame 31. The spacing between the multiple sets of tightening rollers 46 decreases from bottom to top. The tightening rollers 46 further tighten the folded emergency blanket, making it easier to press the emergency blanket.

[0070] A limiting roller 47 is provided between each set of tightening rollers 46 in the longitudinal direction to prevent the emergency blanket from shifting in the horizontal direction and to achieve the limiting function.

[0071] A feeding device 100 is provided above the slitting device 6. The feeding device 100 includes a feeding roller 101 and a feeding motor 102. The feeding roller 101 is located on the front side of the mounting plate 5, and the feeding motor 102 is located on the rear side of the mounting plate 5. A feeding cylinder 103 is provided on the side of the feeding roller 101. The gap between the feeding roller 101 is adjusted by driving the feeding cylinder 103, thereby ensuring that the overall device can adapt to the processing of different specifications (i.e., the thickness of the emergency blanket in the folded state). The emergency blanket to be processed is clamped by the feeding roller 101, and the folded emergency blanket to be processed is provided with the motion power for subsequent processing under the driving action of the feeding motor 102.

[0072] A pressing device 110 is provided between the slitting device 6 and the folding device 7. The pressing device 110 includes pressing rollers 111 and pressing plates 112. The pressing rollers 111 are located on the front side of the mounting plate 5 and are driven by the folding motor 72 via a belt. The pressing plates 112 are located between the pressing rollers 111 and are fixed on the mounting plate 5. The clamping plate is provided with a hollow pressing groove 113. A pressing ring 114 is provided on the pressing rollers 111 corresponding to the pressing groove 113. Utilizing the characteristics of the emergency blanket (which is generally made of tin foil or aluminum film), the emergency blanket is pressed tightly by the pressing ring 114, which can ensure that the emergency blanket is not easily spread out during subsequent processing and use. The O-ring reduces the contact area between the emergency blanket and the emergency blanket to prevent deformation. The emergency blanket is then transported into the folding rollers by power.

[0073] The folding device 7 has peeling devices 120 on both sides. Each peeling device 120 includes a peeling rod 121, a peeling shaft 122, and a drive connecting rod 123. The peeling rod 121 is fixed to the front end of the peeling shaft 122. A peeling groove 124 is provided on the folding roller 71 corresponding to the peeling rod 121. The drive connecting rod 123 is fixed to the rear end of the peeling rod 121. A drive disk 125 is provided on the folding shaft. A drive groove 126 is provided inside the drive disk 125. A rotating shaft is provided at the front end of the drive connecting rod 123. The drive groove 126 has a diagonal protrusion structure. The protrusions in the drive groove 126 are designed to be diagonally protruding. The angle difference between the drive grooves 126 of the peeling devices 120 on both sides is 180°. When the folding roller 71 rotates, it will achieve an operating position of 90°. The protrusions in the drive groove 126 will push the drive linkage 123. The drive linkage 123 will drive the peeling shaft 122 to move and drive the peeling rod 121 to move downward once. After the action is completed, it will quickly return to its original position.

[0074] A receiving device 130 is installed below the palletizing conveyor 8. The receiving device 130 includes a receiving plate 131 and a receiving motor 132. The receiving plate 131 is set in front of the mounting plate 5 through a slot. The receiving motor 132 drives the receiving plate 131 through a belt. The receiving device 130, together with the receiving device, can ensure the smooth progress of the palletizing work. When the receiving and palletizing of the folded emergency blanket is completed, the receiving plate 131 moves up and close to the position below the folding roller 71 under the action of the receiving motor 132. As the emergency blanket falls, the control host 9 controls the receiving motor 132 to move down one by one to complete the receiving of the emergency blanket.

[0075] A receiving plate 133 is set at the horizontal position of the conveyor belt 81. A receiving groove 134 is set on the receiving plate 133 corresponding to the receiving plate 131. The receiving plates 133 are set in pairs. The receiving plates 133, together with the conveyor belt 81, can prevent the folded emergency blanket from deflecting to the left or right during the conveying process.

[0076] The conveyor belt 81 is mounted on a movable frame, which is connected by an adjusting screw. The adjusting screw is fixed to the front of the mounting plate 5. The position of the movable frame can be adjusted up and down by adjusting the screw, thereby driving the conveyor belt 81 to move up and down. This allows the distance between the conveyor belt 81 and the elastic belt to be adjusted, thus enabling the conveying and palletizing device to transport stacked emergency blankets of different thicknesses.

[0077] The control host 9 is connected to the mounting plate 5 via a rotating rod. Adjustment handles are provided on both sides of the control host 9. The position of the control host 9 can be easily adjusted by rotating the rod and adjusting the handles, which facilitates the control and operation of the device.

[0078] Working principle

[0079] Prepare for the processing of emergency blankets by setting relevant data for the emergency blankets to be processed through the control host 9, and adjusting the palletizing and conveying device 8 according to the feedback suggestions from the device control host 9.

[0080] When the device is working normally, firstly, the feeding arm 141 lifts the material roller 146 containing the semi-finished emergency blanket onto the support plate 143 via the feeding cylinder 142, and places the material roller 146 at the position of the rotating bearing 145. At the same time, the front end of the Y-shaped feeding arm 141 forms a fixing structure with the limiting buckle 144 to limit and fix the material roller 146. Then, the emergency blanket roll is manually wrapped around the tension roller 150, passes through the folding plate 23, the collecting roller, and the limiting roller 47, and then... The pressing roller 4 presses the emergency blanket. Specifically, the adjusting roller 42 is moved by the adjusting cylinder 45 to adjust the gap between the fixed roller 41 and the adjusting roller 42, which is suitable for pressing emergency blankets of different thicknesses. At the same time, the fan 25, the feeding motor and the pressing motor 43 of the whole device are controlled to work. At the same time, the fan 25 works to extract the air in the air chamber 22 and draw the air in through the air holes of the folding plate 23, so that the emergency blanket roll is pressed tightly against the folding plate 23, and the emergency blanket is folded in conjunction with the folding wheel 27.

[0081] Then, the first aid blanket that has been folded horizontally and is ready for further processing enters the feeding device 100 through the guide roller. The feeding motor 102 drives the feeding roller 101 to rotate, thereby providing feeding power to the first aid blanket entering the device and sending it to the slitting device 6. The control host 9 rotates the slitting roller 61 according to the preset required first aid blanket specifications, and the cutter 63 completes the slitting of the first aid blanket (one rotation of the slitting roller 61 completes one cut).

[0082] Next, the slit emergency blanket enters the pressing device 110. Under the action of the pressing rollers 111, the emergency blanket is pressed by the pressing ring 114 and then enters the folding device 7. The emergency blanket enters vertically into the middle position of the folding rollers 71. The folding heads 75 and clamping heads 76 of the corresponding two folding rollers 71 are 90° apart. The emergency blanket is inserted between the pressing head 76 and the folding rollers 71 by the folding head 75. At the same time, the emergency blanket is clamped and folded under the tension of the spring. As the folding rollers 71 rotate, the drive disc 79 and the limiting ring 74 contact the drive rod 78, which drives the folding rod 77 to move. The folding head 75 loosens the edge of the folded emergency blanket; the folding rollers 71 of the splitting device 7 repeat the above steps to complete the left and right folds in sequence. At the same time, the drive groove 126 has a diagonal protrusion structure design. Through the protrusions set in the drive groove 126, and the angle difference between the drive grooves 126 of the peeling devices 120 on both sides is 180°, the splitting rollers 71 will achieve a 90° operating position while rotating. The protrusions in the drive groove 126 will push the drive linkage 123, which will drive the peeling shaft 122 to move and drive the peeling rod 121 to move downward once. After the action is completed, it will quickly return to its original position.

[0083] Next, the folded emergency blanket falls under the influence of gravity, the stacking device 130 is activated, and the stacking plate 131 starts near the lower position of the folding roller 71, and the folded emergency blanket falls onto the stacking plate 131.

[0084] Finally, the palletizing and conveying device 8 operates, with the conveyor motor 82 driving the conveyor belt 81 to transport the first aid blanket. The folded first aid blanket is placed on the conveyor belt 81 between the partition plates 83, thus completing the transport of the palletized folded first aid blanket to the next packaging unit for further processing. In this way, the device completes the horizontal folding, cutting, vertical folding, and palletizing and conveying processing operations of the first aid blanket.

[0085] While the device is working, the feeding belt 160 continuously adjusts its height according to the thickness of the emergency blanket roll to keep it in close contact, and adjusts the material roller 146 horizontally according to the offset of the emergency blanket roll through the adjusting rod 147 to ensure the smooth progress of the overall processing work.

[0086] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
