[0002] In modern agriculture, the widespread use of greenhouses provides a good environment for the growth of crops. However, in winter or cold areas, the thermal insulation performance of greenhouses is directly related to the growth rate and quality of crops. Agricultural insulation is an important thermal insulation material for greenhouses, and its preparation process has a crucial impact on the thermal insulation effect and durability.

[0003] For example, patent number CN1319324A discloses a method for making a composite thermal insulation quilt, which mainly includes overlapping polyethylene foam and waterproof tarpaulin on the outer surface of the felt from the inside to the outside, and fixing them with the outer surface as a whole, compounding a layer of reflective film on the inner surface of the felt, and connecting the reflective film and the felt by hot pressing and bonding. The process steps mainly solve the problems of short service life and poor thermal insulation effect of the existing technology.

[0004] However, there are still some problems in the existing agricultural thermal insulation blanket preparation process. First, it is often difficult to achieve integrated vibration compaction during the processing of the thermal insulation blanket, resulting in uneven distribution of fibers inside the thermal insulation blanket, affecting the thermal insulation effect. Secondly, the double-sided cutting process is complicated, and it is difficult to ensure cutting accuracy and efficiency. Finally, after cutting, there are often residual threads or impurities on the surface of the thermal insulation blanket, which requires additional manual cleaning, increasing production costs and time. Summary of the invention

[0006] The technical solution of the present invention to solve the above technical problems is as follows: A preparation process of an agricultural thermal insulation blanket comprises the following steps: S1, using the differential rotation of the differential motor and the guide shaft to maintain the set tension of the material; S2, the transmission module drives the annular lower pressure belt, the annular upper pressure belt and the two annular side pressure belts to rotate synchronously to perform preliminary compaction on the material; S3, changing the distance between the annular upper pressing belt and the annular lower pressing belt to achieve reciprocating compaction and shaping of the thermal insulation quilt; S4, adjusting the distance between the two trimming components and setting the trimming position; S5, the thermal insulation quilt is quickly cut, and the waste is collected by a waste roller; S6. Clean the cut insulation blanket to remove excess threads or impurities; The above steps are based on the preparation equipment of the agricultural thermal insulation quilt, which includes a frame, on which a transmission module, a pressure-vibration component, an annular lower pressure belt, a quilt tensioning mechanism, a distance adjustment module and a quilt surface cleaning mechanism are installed. The pressure-vibration component is transmission-connected with a quilt pressing frame, and the inner walls of the quilt pressing frame are respectively transmission-connected with an annular upper pressure belt and two symmetrically arranged annular side pressure belts, the annular lower pressure belt and the two annular side pressure belts are both transmission-connected with the transmission module, and pressure strips are equidistantly installed on the annular side pressure belts, and universal pressure beads are equidistantly installed on each of the pressure strips, and two mirror-arranged trimming components are transmission-connected on the distance adjustment module, and a guide shaft driven by a servo motor is rotatably connected to the frame, and the two trimming components are both transmission-connected with the guide shaft.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the material tensioning mechanism includes two first clamping rollers symmetrically arranged and rotatably connected to the frame and two second clamping rollers symmetrically arranged and rotatably connected to the frame, a gap for clamping and conveying the heat-insulated material is fixedly arranged between the two first clamping rollers and between the two second clamping rollers, a first linkage gear is fixedly installed on the tail ends of the two first clamping rollers, the two first linkage gears are meshed with each other, a second linkage gear is fixedly installed on the tail ends of the two second clamping rollers, the two second linkage gears are meshed with each other, a differential motor is installed on the frame, the output shaft end of the differential motor is transmission-connected to the second clamping roller, and the guide shaft is transmission-connected to the first clamping roller through a first chain belt.

[0009] The beneficial effect of adopting the above-mentioned further scheme is that when the thermal insulation quilt is trimmed, the differential motor and the guide shaft rotate differentially, and the rotational speed of the differential motor is slightly higher than the rotational speed of the guide shaft, which is maintained by the rotational speed difference between the second clamping roller and the first clamping roller, so that the thermal insulation quilt is kept at a set tension during trimming.

After the pressure frame reciprocates within the set stroke, the spacing between the annular lower pressure belt and the annular upper pressure belt is reciprocated. Through the reciprocating change of the spacing between the annular lower pressure belt and the annular upper pressure belt, the annular upper pressure belt can cooperate with the annular lower pressure belt, and then the thermal insulation blanket to be processed and cut is reciprocated and compacted and shaped. Through compaction and shaping, the subsequent double-sided cutting of the thermal insulation blanket is facilitated.

[0022] The beneficial effects of the present invention are: When the present invention is working, it can realize vibration compaction, double-sided cutting and back cleaning after cutting during the processing of the thermal insulation quilt in an integrated manner. By realizing the above functions, the functionality of the preparation device and the processing efficiency of the thermal insulation quilt are effectively improved.

[0023] 2) When the thermal insulation blanket is processed in the present invention, the first transmission roller is driven.

After the gear shaft rotates, the half-missing gear, the vibration transmission gear plate and the elastic reset member are set, so that the pressure frame can reciprocate within the set stroke. After the pressure frame reciprocates within the set stroke, the spacing between the annular lower pressure belt and the annular upper pressure belt is reciprocated.

[0024] 3) When the thermal insulation quilt is trimmed in the present invention, the differential motor and the guide shaft rotate differentially, and the rotation speed of the differential motor is slightly higher than the rotation speed of the guide shaft, which is maintained by the rotation speed difference between the second clamping roller and the first clamping roller, so that the thermal insulation quilt is kept at a set tension during trimming. By maintaining the tension of the thermal insulation quilt, the trimming accuracy of the thermal insulation quilt is effectively improved.

[0025] 4) When the quilt cover is cleaned in the present invention, the two negative pressure shafts rotate at a set speed. When the two negative pressure shafts rotate, the negative pressure flow channel generates negative pressure. After the negative pressure flow channel generates negative pressure, the positive spiral bristles and the reverse spiral bristles are set to achieve double-sided cleaning of the quilt cover through negative pressure and physical cleaning methods. By cleaning both sides of the quilt cover, excess cotton wool or cotton wool generated when the quilt cover is cut can be removed, which is beneficial to the rapid sewing and edge sealing of the thermal insulation quilt after the edge is cut.

[0030] The material tensioning mechanism comprises two first clamping rollers 9 symmetrically arranged and rotatably connected to the frame 1 and two second clamping rollers 10 symmetrically arranged and rotatably connected to the frame 1. A gap for clamping and conveying the heat-insulating material is fixedly arranged between the two first clamping rollers 9 and between the two second clamping rollers 10.

[0031] When the thermal insulation quilt is trimmed, the differential motor 11 and the guide shaft 8 rotate differentially, and the rotation speed of the differential motor 11 is slightly higher than the rotation speed of the guide shaft 8, which is maintained by the rotation speed difference between the second clamping roller 10 and the first clamping roller, so that the thermal insulation quilt is kept at a set tension during trimming. By maintaining the tension of the thermal insulation quilt, the trimming accuracy of the thermal insulation quilt is effectively improved.

[0032] The transmission module includes two first transmission rollers 13 rotatably connected to the frame 1 and two second transmission rollers 14 rotatably connected to the pressing frame 3. The two first transmission rollers 13 are both transmission-connected to the annular lower pressing belt 2, and the two second transmission rollers 14 are both transmission-connected to the annular upper pressing belt 4. Linkage modules are installed on the frame 1 and at positions corresponding to the two annular side pressure belts 5. Active bevel gears are installed on the two first transmission rollers 13. The two linkage modules are respectively connected to the two active bevel gears. A first transmission roller 13 is connected to a first clamping roller 9 through a second chain belt.

[0034] When the heat preservation blanket is prepared, the first transmission roller 13, the second transmission roller 14 and the third transmission roller 15 rotate at the same speed. After the first transmission roller 13, the second transmission roller 14 and the third transmission roller 15 rotate at the same speed, the annular lower pressure belt 2, the annular upper pressure belt 4 and the annular side pressure belt 5 rotate at the same speed. The pressure-vibration component includes a third chain belt, a gear shaft 16 rotatably connected to the frame 1, and a tensioning frame 17 slidably connected to the frame 1, and a tensioning shaft 18 is rotatably connected to the tensioning frame 17; Another first transmission roller 13, a gear shaft 16, a tensioning shaft 18 and a second transmission roller 14 are all connected to the third chain belt in a transmission manner; A group of tensioning springs 19 are installed between the tensioning frame 17 and the frame 1, two symmetrically arranged half-missing gears 20 are installed on the gear shaft 16, a pressure frame 21 is provided above the pressure frame 3, and a group of T-shaped guide rods 22 are installed on the top surface of the pressure frame 3, each T-shaped guide rod 22 is slidably connected to the pressure frame 21, and a compression spring 23 is sleeved on each T-shaped guide rod 22 and at a position corresponding to the pressure frame 3 and the pressure frame 21; Vibration transmission tooth plates 24 are installed on the pressure frame 21 and at positions corresponding to the two half-missing gears 20.

After the pressure frame 21 reciprocates within the set stroke, the spacing between the annular lower pressure belt 2 and the annular upper pressure belt 4 is reciprocated. Through the reciprocating change of the spacing between the annular lower pressure belt 2 and the annular upper pressure belt 4, the annular upper pressure belt 4 can cooperate with the annular lower pressure belt 2, and then the thermal insulation blanket to be processed and cut is reciprocated and compacted and shaped. Through compaction and shaping, the subsequent double-sided cutting of the thermal insulation blanket is facilitated.

By cleaning both sides of the quilt surface, excess cotton wool or cotton wool generated when the quilt surface is cut can be removed, which is beneficial to the rapid sewing and edge sealing of the thermal insulation quilt after cutting.
