Description

Technical Field

[0001] The invention relates to the technical field of conveying and folding a thermal insulation blanket, and in particular to a thermal insulation blanket folding and shaping device in a greenhouse. Background Art

[0002] Thermal insulation blanket is a kind of high-efficiency and energy-saving production facility. Due to its low construction cost and good insulation effect, many agricultural producers use it in production. In order to minimize heating costs and improve efficiency, how to enhance the insulation capacity of greenhouses and reduce heat loss, many greenhouse users are using various thermal insulation blankets. Since the thermal insulation blanket occupies a large area, it is necessary to use folding equipment to transport and fold the thermal insulation blanket after use, storage and transportation.

[0003] Chinese patent document CN221317854U discloses a folding device for a heat preservation blanket in a greenhouse, which relates to the technical field of heat preservation blankets and includes a dehumidification mechanism. A folding mechanism is fixedly installed at the bottom of the dehumidification mechanism, and the folding mechanism includes a base.

[0004] In daily use of the prior art, the thermal insulation blankets used in greenhouses have a certain length, and are generally transported and folded in a rolling manner. Due to their heavy thickness, they take a long time to roll up, and someone must be on site to observe to prevent damage caused by uneven folding of the thermal insulation blanket. This makes the overall automation of the equipment insufficient, and it is impossible to detect the folding degree of the thermal insulation blanket. After folding, personnel are required to manually disassemble it, and manual transportation greatly wastes personnel's time and also reduces the working efficiency of the equipment. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a folding and shaping device for thermal insulation blankets in a greenhouse, which can effectively solve the problem in the prior art that the degree of thermal insulation blanket rolling cannot be automatically detected and manual handling and stacking are required.

[0018] Preferably, a support plate is fixedly installed on the left end of the support base, and an upper trapezoidal plate is fixedly installed on the upper side of the right end of the support plate.

[0019] Preferably, the inner cross tube located on the rear side is drivingly connected to the reciprocating screw, and the inner cross tube located on the front side is fixedly connected to the limit plate.

[0020] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0021] First, by setting up the arc-shaped support bar, when the equipment completes rolling up the thermal insulation quilt, the thermal insulation quilt with increasing volume will squeeze the arc-shaped support bar to make it flip downward, so that the equipment can detect the rolling process of the thermal insulation quilt, and the equipment can immediately identify that the thermal insulation quilt has been rolled up, and cooperate with the motor and transmission components therein to control the arc-shaped support bar to move upward, so that the equipment can achieve the purpose of automatic stacking of the folded thermal insulation quilt. In this way, the equipment will have a certain degree of automation, which effectively improves the use efficiency.

[0022] Second, during the process of rolling up the thermal quilt, two of the jet racks will continuously spray air toward the thermal quilt, and the jet rack located at the bottom will swing back and forth with the semi-tooth plate. The continuously heated jet rack can not only dry the moisture in the thermal quilt better, but also effectively clean the impurities on the surface of the thermal quilt, ensuring that the folded thermal quilt can be tidy.

[0023] Third, when the insulation blanket is in the stacking process, the air in the fixed tube cannot enter the L-shaped tube, so the jet rack at the bottom will stop jetting, while the jet rack at the top will not only continue to jet, but also increase the wind force it sprays, which can better clean the impurities remaining in the drying box. This mechanism will clean the drying box cavity before each winding work, so that the equipment will not have impurities accumulation, ensuring that it can always be used normally.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present invention will be further described below in conjunction with the embodiments.

[0040] Example: Refer to Figures 1 to 12 , a greenhouse insulation blanket folding and shaping equipment, comprising:

[0041] Support base 1;

[0042] The drying mechanism 2 includes a drying box 21. Two jet racks 25 are arranged in the upper and lower parts of the drying box 21. When the thermal insulation cotton is folded and shaped, the jet rack 25 located at the lower part stops jetting, and the jet rack 25 located at the upper part continues jetting.

[0043] The trigger mechanism 5 includes an arc-shaped support bar 55 and a counterweight 58. The thermal blanket is rolled up and folded. The volume of the thermal blanket will continue to increase during the rolling process, pressing the arc-shaped support bar 55 to rotate downward. When the thermal blanket is folded, the arc-shaped support bar 55 will rotate to the maximum extent to move the counterweight 58 downward.

[0044] The exhaust mechanism 3 includes an L-shaped tube 33 and an air duct assembly 34. The L-shaped tube 33 is connected to a sealing tube 35. When the device completes folding the thermal insulation cotton, the air duct assembly 34 closes the air duct entering the L-shaped tube 33 and the sealing tube 35, so that the gas cannot enter the L-shaped tube 33, and the air supply to the jet frame 25 located at the lower side is stopped;

[0045] The folding mechanism 4 includes two inner cross tubes 451 and a cross block 1 458. A cross block 2 459 is provided on both sides of the cross block 1 458. The two cross blocks 2 459 are connected to the cross block 1 458 by telescopic rods. The positions of the cross blocks 1 458 and 459 are controlled by the air entering the L-shaped tube 33. When the cross block 1 458 is located in the inner cross tube 451 on the front side, the device performs the folding work. When the cross block 1 458 is located in the inner cross tube 451 on the rear side, the device can automatically stack the folded insulation blankets.

[0046] In order to better clean the moisture and impurities on the insulation quilt, Figure 3 As shown, a blocking frame 22 is fixedly installed on the upper surface of the drying box 21, and the folded insulation quilt is stacked on the drying box 21, wherein the blocking frame 22 can block the rolling insulation quilt, and a packing device is provided between the drying box 21 and the hydraulic caliper 41 and the limit plate 42 to bundle and pack the rolled insulation quilt to prevent it from being scattered due to rolling. A hydraulic clamping roller 23 is fixedly installed on the right end of the drying box 21, and the hydraulic clamping roller 23 can squeeze the insulation quilt to reduce the moisture in the insulation quilt in advance;

[0047] Then, an electric heating wire plate 24 is fixedly installed on the middle part of the inner wall of the drying box body 21, and a semi-toothed plate 26 is rotatably installed at the rear end of the drying box body 21. A torsion spring 1 is provided between the semi-toothed plate 26 and the drying box body 21, and the semi-toothed plate 26 is fixedly connected to the jet frame 25 located below through an axis. The torsion spring 1 allows the semi-toothed plate 26 and the jet frame 25 to rotate upward by a certain angle, and a toothless plate 27 is meshed with the lower side of the semi-toothed plate 26. Under the meshing action of the gears, the toothless plate 27 can drive the semi-toothed plate 26 and the jet frame 25 to rotate to one side. After the toothless plate 27 is no longer meshed with the semi-toothed plate 26, the torsion spring 1 drives the jet frame 25 to reset, so that the jet frame 25 located below swings back and forth, so as to better clean the impurities on the surface of the insulation quilt.

[0048] In order to provide air to the two jet racks 25, as Figure 4As shown, the exhaust mechanism 3 includes a blower 31, an exhaust duct 32 is fixedly installed at the output end of the blower 31, an L-shaped tube 33 is connected to a sealing tube 35, the sealing tube 35 is connected to the jet frame 25 located below by a bellows, and a sealing blade 36 is rotatably installed in the sealing tube 35. The horizontal end surfaces of the sealing blades 36 are all provided with arc grooves 37, and the sealing blades 36 are tightly fitted with the inner wall of the sealing tube 35. When air enters the sealing tube 35 through the L-shaped tube 33, in order to flow from the pipe on the other side to the bellows, the sealing blades 36 are pushed to rotate. The arc grooves 37 provided can increase the contact area between the sealing blades 36 and the air, so that the air can better push the sealing blades 36 to rotate, and the sealing blades 36 are connected to the toothless plate 27 by belt drive, that is, when the device is in the process of folding, the sealing blades 36 will provide power for the toothless plate 27.

[0049] In order to clean the impurities in the drying box 21, Figure 5 As shown, a fixed pipe 341 is fixedly installed at the upper end of the exhaust duct 32, and a plurality of arc-shaped holes 342 are arranged in a circumferential array on the inner wall of the fixed pipe 341. The air in the exhaust duct 32 first enters the fixed pipe 341, and then enters the L-shaped pipe 33 through the plurality of arc-shaped holes 342. A movable pipe 343 is slidably installed on the fixed pipe 341, and an elastic spring 344 is fixedly installed at the lower end of the movable pipe 343. The upper end of the movable pipe 343 is connected to a ventilation pipe 345. When the insulation blanket is completely rolled up, the counterweight block 58 will drive the ventilation pipe 345 and the movable pipe 343 to move downward at the same time. The movable pipe 343 will block the arc hole 342 so that air can no longer enter the L-shaped pipe 33. The jet rack 25 located below will not only be unable to spray but also will no longer swing back and forth. The ventilation pipe 345 is connected to the jet rack 25 located above by a bellows. By using the bellows connection, the ventilation pipe 345 will not affect the connection status with the jet rack 25 when it moves.

[0050] In order to roll and fold the thermal insulation quilt, Figure 6 As shown, a hydraulic caliper 41 is provided at the left end of the drying box 21. The hydraulic caliper 41 adopts a hydraulic method, and the two rollers therein can be extended and moved. When the two rollers clamp the insulation, the insulation blanket can be rolled up as long as the limit plate 42 drives it to rotate. A limit plate 42 is provided on the rear side of the hydraulic caliper 41, and a support frame 43 is provided on the rear side of the limit plate 42. A motor 44 is fixedly installed on one side of the support frame 43, and a transmission assembly 45 is provided at the output end of the motor 44. The motor 44 provides power for the rotation of the limit plate 42 and the hydraulic caliper 41.

[0051] In order to achieve the purpose of automatic stacking after winding is completed, Figure 7As shown, the transmission assembly 45 includes a connecting pipe 452, a hydraulic pipe 454 is arranged in the inner cross pipe 451 at the rear side, the hydraulic caliper 41 is connected to the hydraulic pipe 454 by a coupling, the hydraulic pipe 454 and the L-shaped pipe 33 are communicated with each other, the air in the L-shaped pipe 33 can enter the hydraulic pipe 454, a movable block 455 is slidably installed on the rear side of the inner cavity of the hydraulic pipe 454, a tension spring 456 is arranged between the movable block 455 and the inner wall of the hydraulic pipe 454, a piston rod 457 is slidably installed in the inner cavity of the hydraulic pipe 454, hydraulic oil is arranged between the movable block 455 and the piston rod 457, when the movable block 455 moves, the hydraulic oil will be squeezed to push the piston rod 457 to move, when the arc hole 342 is blocked by the movable pipe 343, the air cannot enter the L-shaped pipe 33, and the tension spring 456 therein will drive the movable block 455 and the piston rod 457 to reset;

[0052] Furthermore, the piston rod 457 is fixedly connected to the cross block 458, the inner cross tube 451 located on the rear side is transmission-connected to the reciprocating screw 52, ​​and the inner cross tube 451 located on the front side is fixedly connected to the limit plate 42. When the cross block 458 is located in the front inner cross tube 451, the motor 44 will drive the limit plate 42 to rotate, and the equipment will reel in the thermal insulation quilt. When the cross block 458 is located in the rear inner cross tube 451, the motor 44 will drive the reciprocating screw 52 to rotate, and the equipment will move the reeled thermal insulation quilt upwards, thereby achieving the purpose of automatic stacking of the thermal insulation quilt.

[0053] In order to detect the rolling status of the thermal insulation quilt, Figure 8 , Fig. 9 as well as Fig.10 As shown, a support plate 51 is fixedly installed on the left end of the support base 1, and an upper trapezoidal plate 50 is fixedly installed on the upper side of the right end of the support plate 51. The support plate 51 is provided with an upper groove and a lower groove, and a reciprocating screw rod 52 is vertically rotatably installed on the inner wall of the upper groove. The reciprocating screw rod 52 is sleeved with a shift block 53 used in conjunction with it, and a movable frame 54 is rotatably installed on the right end of the shift block 53 by a telescopic rod. The movable frame 54 is rotatably connected with the arc support bar 55. When the reciprocating screw rod 52 rotates, it will drive the movable frame 54 and the arc support bar 55 to move upward, and a torsion spring 2 is provided between the arc support bar 55 and the movable frame 54;

[0054] Then, when the device is in the initial state, the torsion spring 2 will make the arc support bar 55 rotate upward. During the process of rolling up the insulation quilt, the volume of the insulation quilt will continue to increase, pressing the arc support bar 55 to rotate downward. When the insulation quilt is rolled up, the arc support bar 55 will rotate downward to the maximum extent. By mechanical triggering, the device will automatically detect that the insulation quilt has been rolled up. Two thrust springs 56 are fixedly installed in the lower groove. The right ends of the two thrust springs 56 are fixedly installed with limited spacers. The support plate 51 has a lower trapezoidal plate 59 fixedly mounted on one side thereof, and the counterweight 58 is slidably connected to the lower trapezoidal plate 59. When the arc-shaped support bar 55 rotates downward, it contacts the limit frame 57 and continuously pushes it to move. When the limit frame 57 is completely moved into the lower groove, the counterweight 58 stuck therein will move downward along the lower trapezoidal plate 59.

[0055] The working principle of the present invention is as follows: when in use, the device needs to be moved to a suitable position, and then the thermal insulation quilt is guided out of the drying box 21 by traction, and the hydraulic caliper 41 is started to clamp and fix one side of the thermal insulation quilt. At this time, the blower 31 is started, and the blower 31 will output air to the fixed pipe 341. The air entering the fixed pipe 341 will flow into the L-shaped pipe 33 through the arc hole 342. When the air enters the sealing pipe 35 connected thereto, it will push the sealing blades 36 therein to rotate, and the air will finally enter the two injection racks 25. The surface of the thermal insulation quilt is cleaned by the injection of the injection racks 25. The sealing blades 36 will drive the toothless plate 27 to rotate. Driven by the torsion spring 1 and the toothless plate 27, the injection rack 25 located below will reciprocate to better clean the thermal insulation quilt. At the same time, the electric heating wire plate 24 in the drying box 21 will continue to heat, and the thermal insulation quilt entering the drying box 21 will be dried.

[0056] The air in the L-shaped tube 33 will also flow into the hydraulic tube 454, which can push the movable block 455 and the hydraulic oil therein to move, and the hydraulic oil will push the piston rod 457 and the cross block 1 458 to move. In order to ensure that the cross block 1 458 can move back and forth in the two inner cross tubes 451, the cross block 2 459 can remain in place when it contacts the end face of one side of the inner cross tube 451 and wait until it rotates to coincide with the inner cavity of the inner cross tube 451, so that it can enter the inner cavity of the inner cross tube 451. The same is true in the opposite direction. The cross block 1 458 is pushed by the air to enter the inner cross tube 451 located in the front. At this time, the tension spring 456 will extend with the movement of the movable block 455. At this time, the starting motor 44 can drive the limit plate 42 and the hydraulic caliper 41 to rotate, so that the equipment can perform the insulation winding work;

[0057] When the insulation blanket is completely rolled up, it will be bundled and packed by the packaging device. At this time, the two rollers in the hydraulic caliper 41 are controlled to shorten and retract, and the motor 44 stops driving. The insulation blanket will fall onto the arc support bar 55, and then squeeze the arc support bar 55 to make it rotate downward to the maximum extent. In this process, it will contact the limit frame 57 and continuously push it to move. When the limit frame 57 is completely moved into the lower groove, the counterweight block 58 stuck by it will move downward along the lower trapezoidal plate 59 until it contacts the ventilation pipe 345 and presses it to move downward. The ventilation pipe 345 will drive the movable pipe 343 to move downward to block the arc hole 342, and the air in the fixed pipe 341 will not be able to flow into the L-shaped pipe 33. The jet rack 25 located below will stop swinging and jetting, while the jet rack 25 located above will continue to jet, and the jet volume will increase, so that the impurities remaining in the drying box 21 are blown out from the reserved groove of the drying box 21. The reserved groove is located on the right side of the bottom wall of the drying box 21.

[0058] The movable block 455 which is no longer pushed by the air will be reset by the tension spring 456, so that the piston rod 457 and the cross block 1 458 move backward at the same time, until the cross block 1 458 moves into the inner cross tube 451 at the rear, at this time, the starting motor 44 will drive the reciprocating screw rod 52 to rotate, drive the shifting block 53 therein to move upward, so that the movable frame 54 and the arc-shaped support bar 55 move upward with the rolled and packaged insulation quilt, and when the movable frame 54 moves on the upper trapezoidal plate 50, it will drive the arc-shaped support bar 55 and the insulation quilt to move in the direction close to the drying box 21, and the arc-shaped support bar 55 will shorten inward when it contacts the surface of the drying box 21, and the insulation quilt placed thereon will roll along the top of the drying box 21, completing the entire stacking work;

[0059] The device can detect the rolling process of the thermal insulation quilt, so that the device can recognize that the thermal insulation quilt has been rolled up at the first time. In conjunction with the motor 44 and the transmission assembly 45, the arc-shaped support bar 55 can be controlled to move upward, so that the device can automatically stack the folded thermal insulation quilt, making the device have a certain degree of automation and effectively improving the use efficiency.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
