Description

Technical Field

[0001] The invention relates to the technical field of pearl cotton sheet processing, in particular to a multi-layer pearl cotton sheet hot pressing and laminating device. Background Art

[0002] The thermal insulation performance of multi-layer pearl cotton board can be improved through hot pressing lamination process; the layers of pearl cotton board are more closely combined together, reducing the possibility of air convection and heat conduction, thereby improving the overall thermal insulation effect;

[0003] The existing application number is CN201410586740.8, and the patent document discloses a method of thermally bonding two packaging materials together by adsorbing, picking up and positioning two packaging materials. Specifically, the object to be thermally bonded is put into the feeding space, and the controller can drive the feeding servo motor to make the object to be thermally bonded enter the lower part of the Y-axis driving device, and the Y-axis driving device sucks the object to be thermally bonded and lifts it upward, and the X-axis driving device moves the first tray to a suitable position under the heating platen, and the heating platen moves downward to press the object to be thermally bonded and heats it up, so as to obtain a specific formed packaging profile for packaging, and the heating platen of the Y-axis driving device lifts upward, and then the X-axis driving device moves the first tray away from the heating platen, so that the packaging profile falls and is discharged toward the discharge guide plate, completing a working cycle;

[0004] However, when using the technical solution in the above-mentioned patent document, when thermally joining two profile materials, it is necessary to separately adsorb and pick up the two profile materials, accurately position and dock them, and perform large-area surface heat treatment on the two profile materials, so as to ensure that the two profile materials are firmly combined on the basis of ensuring that the edges of the two profile materials are aligned; however, this solution is limited by the size and quantity of the profile materials: when hot pressing and laminating multi-layer profile materials, it is necessary to repeat the adsorption, picking up and positioning and docking of the profile materials many times, which not only increases the complexity of the operation, but also significantly prolongs the entire processing cycle; and when performing surface heat treatment on larger profile materials, it is necessary to increase the size of the material transfer components and the heating platen, resulting in a significant increase in the overall cost of the equipment, increasing the management cost of the equipment throughout its life cycle, and further affecting the reliability and overall efficiency of the equipment. Therefore, the present application provides a multi-layer pearl cotton board hot pressing and laminating device. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The multi-layer pearl cotton board hot pressing and laminating equipment exemplified in the present invention, because the present application clamps multiple pearl cotton boards through multiple single-point clamping modules, the multiple pearl cotton boards always remain parallel to each other. When the heat treatment operation is carried out by using the thermal bonding plug-in, the surface of the pearl cotton boards on both sides of the thermal bonding plug-in is trimmed as the thermal bonding plug-in moves. Combined with the use of the above-mentioned components, the heat treatment effect on the pearl cotton board is not affected while reducing the overall volume of the thermal bonding plug-in. Therefore, on the basis of ensuring the performance of the heat treatment component, the overall size of the heat treatment component is optimized to reduce the cost of the heat treatment component.

[0019] 2. The multi-layer pearl cotton board hot pressing and laminating equipment of the example of the present invention adjusts the positions of multiple single-point clamping modules, applies traction force to the pearl cotton board from the end of the pearl cotton board, so that the multiple pearl cotton boards are placed in an interval state; then, multiple heat-joining plug-ins are respectively inserted between the multiple pearl cotton boards, and the hot-melt adhesive layer on the surface of the pearl cotton board is heat-treated to make the hot-melt adhesive layer in a semi-molten state, and during the horizontal movement of the heat-joining plug-in, the hot-melt adhesive layer on the surface of the pearl cotton board is scraped to make the distribution of the hot-melt adhesive layer more uniform; multiple single-point clamping modules are arranged at equal intervals and adjusted synchronously, and the traction force applied by the single-point clamping module to various parts of the side of the pearl cotton board remains the same, so that the compressive force exerted on various parts of the multiple pearl cotton boards is balanced, and each layer of the multi-layer pearl cotton board after lamination is not twisted, and the overall use effect is good.

[0020] 3. In the hot pressing and laminating equipment for multi-layer pearl cotton boards exemplified in the present invention, when the heat joint plug-in is inserted between adjacent pearl cotton boards, the heat joint plug-in heat-treats the hot melt adhesive layer on the surface of the pearl cotton board while squeezing the hot melt adhesive layer deep into the surface of the pearl cotton board. When multiple pearl cotton boards are subsequently switched to a stacked state, the hot melt adhesive layers on the surfaces of adjacent pearl cotton boards are easy to adhere together, thereby reducing the extrusion force required for the laminating of the pearl cotton boards and improving the bonding strength of the multi-layer pearl cotton boards, thereby improving the efficiency of the initial docking, surface heat treatment and positioning laminating of multiple pearl cotton boards and shortening the entire processing cycle.

[0021] 4. In the multi-layer pearl cotton board hot pressing and laminating equipment of the example of the present invention, two synchronous control slot arms II are respectively connected to multiple driving columns at the same horizontal height on both sides of the pearl cotton board, so as to automatically adjust the position of the synchronous control slot arm II on the guide seat while synchronously adjusting the vertical positions of multiple single-point clamping modules; and because the conical pushing arm is always located in the center of the two sliding sleeves, the thermal bonding plug-in can be accurately inserted from the middle position of the two pearl cotton boards, and the stability in use is good.

[0022] 5. In the multi-layer pearl cotton board hot pressing and laminating equipment of the example of the present invention, the multiple conical pushing arms connected to the same synchronous control slot arm I are divided into two groups, and the two groups of conical pushing arms are staggered. The spacing distances between the two groups of conical pushing arms and the guide columns are different, so that when multiple pearl cotton boards are stacked together, there will be no collision between adjacent conical pushing arms, so that the pearl cotton boards that can be clamped and laminated by the equipment can be thinner, and the applicability to pearl cotton boards of different sizes is good.

[0023] 6. The hot pressing and laminating equipment for multi-layer pearl cotton sheets in the example of the present invention adjusts the spacing size of adjacent pearl cotton sheets to be slightly smaller than the height size of the heat-bonding plug-in. When the heat-bonding plug-in is inserted between two pearl cotton sheets, the scraping force of the heat-bonding plug-in on the hot melt adhesive layer on the surface of the pearl cotton sheet can be enhanced, and the hot melt adhesive layer can be squeezed deep into the surface of the pearl cotton sheet. During this process, a small bulge will be generated on the pearl cotton sheet at the position corresponding to the heat-bonding plug-in, accompanied by a synchronous small deflection of the torsion sleeve and the clamping end, so that the clamping end is firmly attached to both sides of the pearl cotton sheet, thereby increasing the clamping stability of the pearl cotton sheet.

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0046] Embodiment 1:

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a multi-layer pearl cotton board hot pressing and laminating device, including a machine platform 11, a plurality of single-point clamping modules 3 and a plurality of heat-bonding plug-ins 4; a plurality of pearl cotton boards 1 with hot-melt adhesive layers on their surfaces are stacked on the upper side of the machine platform 11, and a plurality of single-point clamping modules 3 are respectively arranged on both sides of the plurality of pearl cotton boards 1, and the heat-bonding plug-in 4 is movably installed above the machine platform 11, and the heat-bonding plug-in 4 can be inserted between two adjacent pearl cotton boards 1.

[0048] The steps of hot pressing and laminating a plurality of pearl cotton boards 1 using the hot pressing and laminating equipment of the present application are as follows:

[0049] Step 1: stack multiple pearl cotton boards 1 and place them on the upper side of the machine table 11, and perform docking treatment on the multiple pearl cotton boards 1;

[0050] Step 2: Adjust the positions of the multiple single-point clamping modules 3, apply traction to the pearl cotton board 1 from the end of the pearl cotton board 1, so that the multiple pearl cotton boards 1 are placed in an interval state; then, insert the multiple thermal bonding plug-ins 4 between the multiple pearl cotton boards 1, heat-treat the hot melt adhesive layer on the surface of the pearl cotton board 1, so that the hot melt adhesive layer is in a semi-molten state, and during the horizontal movement of the thermal bonding plug-in 4, scrape the hot melt adhesive layer on the surface of the pearl cotton board 1 to make the distribution of the hot melt adhesive layer more uniform.

[0051] Step three: adjust the positions of the multiple single-point clamping modules 3, apply traction to the pearl cotton board 1 from the end of the pearl cotton board 1, so that the multiple pearl cotton boards 1 are placed in an overlapping state, and the multiple pearl cotton boards 1 are bonded together by the semi-molten hot melt adhesive layers on both sides; then, continue to synchronously fine-tune the positions of the multiple single-point clamping modules 3, so that the multiple pearl cotton boards 1 are stacked more compactly, thereby achieving the purpose of compacting the multiple pearl cotton boards 1.

[0052] In step 1, since the edges of the multiple pearl cotton boards 1 are initially aligned, it is convenient for the subsequent positioning and stacking of the pearl cotton boards 1 and simplifies the operation process.

[0053] In step 2, since the present application clamps multiple pearl cotton boards 1 through multiple single-point clamping modules 3, the multiple pearl cotton boards 1 always remain parallel to each other. When the heat treatment operation is implemented using the thermal bonding plug-in 4, as the thermal bonding plug-in 4 moves, the pearl cotton boards 1 on both sides of the thermal bonding plug-in 4 are surface-trimmed. Combined with the use of the above-mentioned components, the heat treatment effect on the pearl cotton board 1 will not be affected while reducing the overall volume of the thermal bonding plug-in 4. Therefore, on the basis of ensuring the performance of the heat treatment component, the overall size of the heat treatment component is optimized to reduce the cost of the heat treatment component.

[0054] In step three, multiple single-point clamping modules 3 are arranged at equal intervals and adjusted synchronously. The traction force applied by the single-point clamping modules 3 to various parts of the side of the pearl cotton board 1 remains the same, so that the compressive force exerted on various parts of the multiple pearl cotton boards 1 is balanced, and the layers of the multi-layer pearl cotton board after overlapping processing are not twisted, and the overall use effect is good.

[0055] When using the above scheme, when the heat-joining plug-in 4 is inserted between adjacent pearl cotton boards 1, the heat-joining plug-in 4 heat-treats the hot-melt adhesive layer on the surface of the pearl cotton board 1 while squeezing the hot-melt adhesive layer deep into the surface of the pearl cotton board 1. When multiple pearl cotton boards 1 are subsequently switched to a stacked state, the hot-melt adhesive layers on the surfaces of adjacent pearl cotton boards 1 are easy to adhere together, thereby reducing the extrusion force required for the overlapping of the pearl cotton boards 1 and increasing the bonding strength of the multi-layer pearl cotton boards, thereby improving the efficiency of the initial docking, surface heat treatment and positioning overlapping of multiple pearl cotton boards, and shortening the entire processing cycle.

[0056] The following are the specific structures and operation modes of the single-point clamping module 3 and the thermal bonding plug-in 4:

[0057] like Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the single-point clamping module 3 includes a sleeve 31, which is vertically slidably connected to the guide column 22 on the size positioning base 21, and the size positioning base 21 is installed on the upper side of the machine table 11. The two sides of the sleeve 31 are respectively connected to the magnetic column 32 and the clamping end 35, and the clamping end 35 is abutted against the end surface of the pearl cotton board 1. A conical push arm 25 is slidably installed between multiple sleeves 31 connected to the same guide column 22, and the magnetic edge 252 on the outer side of the conical push arm 25 is plugged into the I-shaped structure on the magnetic column 32 and is coupled to the magnetic column 32 through magnetic adsorption.

[0058] like Figure 6 , Figure 7 and Fig.14 As shown, a synchronous control slot arm Ⅰ24 is slidably installed on the side of the guide column 22, and a telescopic driver 23 for driving the synchronous control slot arm Ⅰ24 to move horizontally is installed on the guide column 22. A driving column 251 is fixedly installed on the side of the conical pushing arm 25 away from the single-point clamping module 3, and the polygonal shaft on the driving column 251 is slidably connected with the synchronous control slot arm Ⅰ24.

[0059] Start the telescopic drive 23, control the synchronous control slot arm Ⅰ24 to move horizontally, drive the multiple conical pushing arms 25 to move horizontally synchronously, and utilize the inclined surfaces on the upper and lower sides of the conical pushing arms 25 and the magnetic adsorption of the magnetic edge 252 and the magnetic column 32 to achieve the synchronous adjustment of the vertical position of the multiple single-point clamping modules 3, and switch the overlapping placement state and the spaced placement state of the multiple pearl cotton boards 1; in this process, the driving columns 251 on the sides of the multiple conical pushing arms 25 slide vertically in the synchronous control slot arm Ⅰ24, and the multiple sliding sleeves 31 slide vertically on the corresponding guide columns 22.

[0060] like Figure 3 , Fig.10 , Fig.11 , Fig.12 and Fig.13As shown, the thermal joint plug-in 4 includes a shuttle arm 45, which can be inserted between two adjacent pearl cotton boards 1. The shuttle arm 45 has at least two built-in electric heating components 46, and the electric heating components 46 use electric heating wires, electric heating tubes or electric heating rods; ropes 44 are respectively provided on both sides of the shuttle arm 45, and the two ends of the rope 44 are respectively connected to the winding rollers 43 rotatably installed at the two ends of the synchronous control slot arm Ⅱ41, and the synchronous control slot arm Ⅱ41 is equipped with a rotating driver 42 for driving the two winding rollers 43 to rotate separately, and the round rod on the driving column 251 is slidably connected with the synchronous control slot arm Ⅱ41, and the synchronous control slot arm Ⅱ41 slides vertically on the guide seat 14 on the upper side of the machine table 11.

[0061] In this embodiment, the positions of the guide seat 14 and the size positioning base 21 on the machine platform 11 are disassembled and adjusted, and the horizontal positions of the multiple single-point clamping modules 3 are adjusted to achieve the clamping or loosening operation of the pearl cotton board 1.

[0062] Start the two rotating drivers 42 on the synchronous control slot arm II 41 to rotate synchronously, the winding roller 43 on one side releases the rope 44, and the winding roller 43 on the other side winds up the rope 44 to keep the rope 44 straight, driving the thermal bonding plug-in 4 to move horizontally between the two pearl cotton boards 1, heat-treating the hot melt adhesive layer on the surface of the pearl cotton board 1, and scraping the hot melt adhesive layer on the surface of the pearl cotton board 1 to make the distribution of the hot melt adhesive layer more uniform.

[0063] like Figure 3 As shown, the torsion sleeve 34 and the clamping end 35 are relatively long, and the rope 44 is avoided from the edge position of the pearl cotton board 1, so as to avoid adverse effects on the overlapping of multiple pearl cotton boards 1;

[0064] like Fig.11 As shown, the two sides of the synchronous control slot arm II 41 are respectively fixedly installed with limit arms 411, and the rope 44 passes through the limit arms 411 to limit the position of the rope 44 and ensure the movement stability of the thermal joint plug-in 4.

[0065] like Fig.10 As shown, the two synchronous control slot arms Ⅱ41 are respectively connected to multiple driving columns 251 at the same horizontal height on both sides of the pearl cotton board 1, so that while synchronously adjusting the vertical positions of multiple single-point clamping modules 3, the position of the synchronous control slot arm Ⅱ41 on the guide seat 14 is automatically adjusted; and because the conical pushing arm 25 is always located in the center of the two sliding sleeves 31, the thermal bonding plug-in 4 can be accurately inserted from the middle position of the two pearl cotton boards 1, and the stability of use is good.

[0066] like Fig.10 and Fig.11As shown, the ends of multiple vertically adjacent synchronous control slot arms Ⅱ41 are staggered with respect to the positions where the rotation drivers 42 are installed, so that when multiple pearl cotton boards 1 are stacked together, there will be no collision between the rotation drivers 42 on adjacent synchronous control slot arms Ⅱ41, and the structures of the internal components of the equipment are compact and have good integrity.

[0067] like Fig.13 As shown, the cross section of the shuttle arm 45 is shuttle-shaped, and the outer side of the shuttle arm 45 is provided with an anti-adhesion coating, and the anti-adhesion coating can use a silicon dioxide nano-coating or a polytetrafluoroethylene coating to prevent the hot melt adhesive layer on the surface of the pearl cotton board 1 from melting and adhering to the outer side of the shuttle arm 45;

[0068] The moving direction of the shuttle arm 45 is defined as forward, and the front and rear ends of the shuttle arm 45 are thinner, which is convenient for insertion between multiple pearl cotton boards 1. The middle part of the shuttle arm 45 is thicker, and two electric heating components 46 are respectively arranged at the front and rear ends of the shuttle arm 45, which are far away from the middle part of the shuttle arm 45, so that the heat of the electric heating components 46 is dissipated from the openings at the front and rear ends to the surface of the pearl cotton boards 1 on both sides, thereby increasing the uniformity of heat distribution.

[0069] In order to ensure the lamination performance of the multi-layer pearl cotton board 1, Figure 6 , Figure 7 , Fig.11 and Fig.14 As shown, the multiple conical pushing arms 25 connected to the same synchronous control slot arm Ⅰ24 are divided into two groups. The two groups of conical pushing arms 25 are staggered, and the spacing distances between the two groups of conical pushing arms 25 and the guide columns 22 are different. Therefore, when multiple pearl cotton boards 1 are stacked together, there will be no collision between adjacent conical pushing arms 25, so that the pearl cotton boards 1 that can be clamped and stacked by the equipment can be thinner and have better applicability.

[0070] In the present application, the clamping end 35 is provided with a plurality of anti-slip protrusions or positioning needles or adhesive strips that can be inserted into the pearl cotton board 1 on one side close to the pearl cotton board 1; when facing pearl cotton boards 1 of different thicknesses and densities, different types of clamping ends 35 are replaced to clamp the two ends of the pearl cotton board 1 to achieve the purpose of preventing loosening.

[0071] The positioning needle on the side of the clamping end 35 is inserted into the EPE board 1 . The length of the positioning needle can be half of the EPE board 1 , thereby increasing the clamping stability of the EPE board 1 and the compression effect during tightening.

[0072] Embodiment 2:

[0073] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, in this embodiment, the clamping end 35 is connected to the sliding sleeve 31 through a torsion limiter 33 and a torsion sleeve 34, and the torsion limiter 33 is sleeved on the shaft 311 on the side of the sliding sleeve 31; the torsion limiter 33 includes a torsion spring and a disc and a ring connected to the two ends of the torsion spring, the torsion spring and the ring are sleeved on the outside of the shaft 311, the disc is detachably fixedly installed on the end of the shaft 311, the torsion sleeve 34 is sleeved on the outside of the ring and fixedly connected to the ring, and the clamping end 35 is sleeved on the outside of the end of the torsion sleeve 34 and is detachably fixedly connected to the torsion sleeve 34.

[0074] like Fig. 9 As shown, the inner diameter of the ring is larger than the outer diameter of the shaft 311, and the outer diameter of the ring is larger than the outer diameter of the disc; thus, the torsion sleeve 34 can not only be twisted slightly together with the clamping end 35, but also be deflected slightly up and down and left and right together with the clamping end 35.

[0075] By using the above scheme, the spacing size of adjacent pearl cotton boards 1 is adjusted to be slightly smaller than the height size of the thermal bonding plug-in 4. When the thermal bonding plug-in 4 is inserted between the two pearl cotton boards 1, the scraping force of the thermal bonding plug-in 4 on the hot melt adhesive layer on the surface of the pearl cotton board 1 can be enhanced, and the hot melt adhesive layer can be squeezed deep into the surface of the pearl cotton board 1. During this process, a small bulge will be generated at the position of the pearl cotton board 1 corresponding to the thermal bonding plug-in 4, accompanied by a synchronous small deflection of the torsion sleeve 34 and the clamping end 35, so that the clamping end 35 is firmly attached to both sides of the pearl cotton board 1, thereby increasing the clamping stability of the pearl cotton board 1.

[0076] Embodiment three:

[0077] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 4 and Figure 5 As shown, in this embodiment, the guide seat 14 and the size positioning base 21 are both slidably connected to the machine platform 11, and the machine platform 11 is respectively provided with a slide rail 13 and a slide groove for accommodating the guide seat 14 and the size positioning base 21 to be embedded and placed.

[0078] like Figure 5 As shown, a cross arm 15 is provided at the bottom of the machine platform 11, and the cross arm 15 is slidably connected to the machine platform 11. Bevel grooves 151 are symmetrically fixedly installed on both sides of the cross arm 15. T-shaped pins 211 are respectively fixedly installed at the bottom of the two size positioning bases 21, and the T-shaped pins 211 are slidably connected to the bevel grooves 151. A control handle for controlling the sliding of the cross arm 15 is provided on the side of the cross arm 15.

[0079] The control handle is manually moved to move the cross arm 15 horizontally, driving the T-pin 211 to slide in the inclined groove 151, and the two size positioning bases 21 and multiple synchronous control slot arms Ⅱ41 are synchronously controlled to move synchronously, and multiple single-point clamping modules 3 are switched to clamp or relax the pearl cotton board 1. Since the rope 44 can be stretched, the rope 44 will not be damaged when the spacing between the synchronous control slot arms Ⅱ41 on both sides of the shuttle arm 45 changes.

[0080] During this process, since the inclined grooves 151 on both sides of the cross arm 15 are symmetrically arranged, the distances between the two size positioning bases 21 and the middle of the machine table 11 are always kept equal, which effectively prevents the stacked pearl cotton boards 1 from moving on the multiple raised ribs 12, and the placement stability of the pearl cotton boards 1 is good.

[0081] The above operation of this embodiment is more convenient and labor-saving than the technical solution in Embodiment 1.

[0082] Embodiment 4:

[0083] The features common to the third embodiment are not described in detail here. The differences between the third embodiment and the present embodiment are as follows: Figure 5 As shown, in this embodiment, a stud 152 is provided at the end of the control handle, a rotating handle 16 is rotatably installed at the bottom edge of the machine table 11, and a scale line is provided on the outer side of the rotating handle 16. The rotating handle 16 is embedded and installed on the machine table 11 and cannot move along its own axis direction. An internal threaded sleeve 161 is fixedly installed at the end of the rotating handle 16, and the stud 152 is connected to the internal threaded sleeve 161 through threaded transmission;

[0084] Hold the turning handle 16 and rotate it, and use the threaded transmission of the stud 152 and the internal threaded sleeve 161 to drive the stud 152 to move horizontally along its own axis to adjust the distance between the two size positioning bases 21. Since scale lines are provided on the outside of the turning handle 16, the rotation angle is easy to observe. Compared with the technical solution in Example 3, the above operation is more intuitive for grasping the moving distance of the cross arm 15.

[0085] Embodiment five:

[0086] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, a plurality of raised ribs 12 are fixedly installed on the top of the machine table 11, and the plurality of raised ribs 12 are spaced apart from each other. The pearl cotton board 1 at the bottom is overlapped and placed on the upper side of the plurality of raised ribs 12, and the moving resistance of the pearl cotton board 1 is reduced by reducing the contact area between the pearl cotton board 1 and the supporting surface, so as to adjust the placement position of the pearl cotton board 1.

[0087] In the present application, the telescopic drive uses a linear electric cylinder or a hydraulic cylinder that can be purchased on the market; the rotation drive uses a stepper motor or a servo motor that can be purchased on the market.

[0088] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.

[0089] Except for the technical features described in the specification, the remaining technical features are known technologies to those skilled in the art. In order to highlight the innovative features of the present invention, the remaining technical features will not be described here in detail.
