Description

Technical Field

[0001] The invention relates to the field of grid film production, and in particular to cooling and shaping equipment for grid film production. Background Art

[0002] Mesh film is a thin film material with a mesh structure, which is widely used in agriculture, construction, packaging and other fields. It is characterized by being lightweight, durable, breathable, and having certain strength and flexibility.

[0003] Cooling and shaping during the production of mesh film is the key to ensure that the mesh film can be cooled quickly and evenly after extrusion and maintain its structural stability and dimensional accuracy. The design and optimization of this equipment is crucial to improving product quality, production efficiency and reducing defects such as edge lift.

[0004] For a mesh film with a certain thickness, since the mesh film is transported by a conveyor belt before being formed after production, the bottom of the mesh film adheres to the conveyor belt. Therefore, when the mesh film is cooled and formed, since the bottom of the mesh film contacts the conveyor belt, the mesh film can only be cooled from the upper surface downwards during cooling, so that the cooling speed of the lower surface of the mesh film is slow, and deformation defects may occur due to uneven cooling speed during cooling and forming of the mesh film. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a cooling and shaping device for grid film production.

[0006] In a first aspect, the present invention provides a cooling and shaping device for producing a grid film, comprising a conveyor belt, and further comprising:

[0007] A plurality of boxes are arranged in a linear array, and the conveyor belt drives the grid film to pass through each of the boxes in sequence;

[0008] A plurality of synchronous cooling components are respectively installed inside each of the boxes, and the cooling temperature of each synchronous cooling component gradually decreases along the conveying direction of the conveyor belt;

[0009] The synchronous cooling assembly includes two cooling belts, the two cooling belts cool and shape the top surface and the bottom surface of the grid film respectively, and the two cooling belts are synchronously transmitted with the grid film;

[0010] The top surface of the cooling belt located below is in contact with the bottom surface of the conveyor belt;

[0011] The conveyor belt and the cooling belt are both conveyor belts made of heat-conducting materials;

[0012] After the production and forming of the mesh film is completed, it is conveyed by a transmission belt, so that the mesh film is driven by the transmission belt to pass through each box in turn. The synchronous cooling component arranged inside the box can synchronously cool and shape the upper and lower surfaces of the mesh film through the two cooling belts arranged, so that the mesh film can be synchronously cooled on the upper and lower surfaces during the cooling process. On the one hand, the synchronous cooling of the upper and lower sides is conducive to improving the cooling speed of the mesh film. On the other hand, the synchronous cooling of the upper and lower sides is conducive to avoiding the uneven cooling temperature of the upper and lower sides of the mesh film, thereby causing deformation defects of the mesh film during the cooling and shaping process.

[0013] In addition, during the cooling and shaping process of the grid film, the lower surface is supported by the transmission belt and the lower cooling belt, and the upper surface is supported by the upper cooling belt, so that during the cooling process of the grid film, the upper and lower surfaces are supported synchronously, which plays a clamping role on the grid film, so that before the grid film is completely cooled and shaped, the upper and lower surfaces have no space for deformation and curling under the clamping effect, and the grid film remains in a straight state until it is completely cooled and shaped, which is conducive to avoiding the deformation defect of the grid film caused by uneven cooling during the cooling and shaping process;

[0014] The cooling belt is conveyed synchronously with the grid film, so that the cooling belt maintains the same speed as the grid film and the conveyor belt during the cooling process, so that the cooling belt is helpful to avoid friction with the grid film during the process of cooling the grid film, which may cause the grid film to be damaged due to friction.

[0015] Preferably, the synchronous cooling assembly further comprises:

[0016] Two groups of first rotating rollers, two of the first rotating rollers form one group, the two groups of the first rotating rollers are symmetrically rotatably installed inside the box, and the two cooling belts are respectively driven and installed on the outer rings of the two groups of the first rotating rollers;

[0017] Two first motors are fixedly mounted on the side wall of the box, and the two first motors respectively drive one of the two groups of the first rotating rollers to rotate;

[0018] Two cooling water guide assemblies are respectively installed on the inner rings of the two cooling belts to evenly circulate and cool the cooling belts;

[0019] After the first motor is started, the output shaft drives the first rotating roller to rotate, and after the first rotating roller rotates, the cooling belt is driven to drive, so that the driven cooling belt cools and shapes the grid film;

[0020] The cooling water guide assembly can circulate and cool the two cooling belts, so that the two cooling belts are in contact with the grid film or the conveyor belt after cooling, so that the cooling belts cool and shape the grid film, or the cooling belts cool the conveyor belt, and the conveyor belt cools and shapes the grid film, which is conducive to the synchronous cooling and shaping of the upper and lower sides of the grid film;

[0021] After the cooling belt passes through the position for cooling and shaping the grid membrane, the cooling water guide assembly cools the cooling belt so that when the cooling belt is again transmitted to the position for cooling and shaping the grid membrane, the cooling belt can be cooled again, thereby cooling and shaping the cooling belt.

[0022] Preferably, the cooling water guide assembly comprises:

[0023] A condenser is fixed inside the box and passes through the inner circle of the cooling belt;

[0024] A plurality of cooling water channels are arranged in a linear array, both ends of all the cooling water channels are respectively connected to the two sides of the condenser, the cooling water channels are filled with cooling water, and the cooling water is cooled when passing through the condenser;

[0025] A plurality of make way grooves are respectively formed on the outer walls of the two first rotating rollers, and when the first rotating rollers rotate, the make way grooves make way for the positions of the cooling water channels;

[0026] The condenser can cool the cooling water passing through, so that the cooling water inside the cooling water channel can be cooled when passing through the condenser, so that the cooling water after cooling can cool the cooling water channel. The cooling water channel is made of heat-conducting material, so that the cooling water channel can cool the cooling belt after cooling, thereby achieving cooling of the cooling belt;

[0027] The make way groove can make way for the cooling water channel, so that the cooling water channel passes through the make way groove when the first rotating roller rotates, so that the cooling water channel can repeatedly contact and cool the cooling belt, which is beneficial to improving the cooling efficiency of the cooling belt.

[0028] Preferably, the synchronous cooling assembly further comprises:

[0029] Two groups of temperature sensors, two of which form a group, are fixed inside the box;

[0030] The two groups of temperature sensors are respectively located at the two ends of the two cooling belts facing the grid membrane, and detect the temperature of the grid membrane when the cooling belts start cooling the grid membrane and the temperature when the cooling ends each time;

[0031] A plurality of cooling auxiliary components are arranged in one-to-one correspondence with the cooling water channels, and are respectively used to further cool the cooling water inside each cooling water channel;

[0032] A plurality of temperature-raising components are arranged in one-to-one correspondence with the cooling water channels, and are respectively used to heat the cooling water inside each cooling water channel, and the cooling water cools the grid membrane after passing through the cooling auxiliary component and the temperature-raising component in sequence;

[0033] The temperature sensor can detect the temperature when the cooling belt starts to cool and form the mesh film and the temperature when the cooling belt ends to cool and form the mesh film, so that the temperature when the cooling belt starts to cool and form the mesh film is the same as the temperature when the cooling belt inside the previous box ends to cool and form the mesh film, so that the cooling temperatures inside each box are connected to each other, thereby avoiding the situation where the mesh film is excessively deformed and causes deformation defects due to excessive temperature difference during cooling;

[0034] When it is detected that the temperature of the cooling belt at the end of cooling the mesh film is too low, resulting in a large cooling temperature difference with the previous box body, the heating component is controlled to heat the cooling water inside the cooling water channel, so that the temperature of the cooling belt at the beginning of cooling the mesh film rises, thereby helping to reduce the cooling temperature difference when the cooling belts inside each box body cool the mesh film for finalizing.

[0035] When it is detected that the temperature of the cooling belt is too high when it finishes cooling and molding the grid membrane, the cooling and molding temperature of the grid membrane is too high, which will cause the cooling efficiency of the grid membrane to decrease. At this time, the cooling auxiliary component is controlled to start, so that the cooling auxiliary component cools the cooling water inside the cooling water channel again, thereby reducing the temperature of the cooling belt when it starts to cool and mold the grid membrane, which is beneficial to improve the cooling efficiency of the grid membrane.

[0036] Preferably, the cooling auxiliary component comprises:

[0037] A plurality of telescopic cooling blocks are arranged in one-to-one correspondence with the cooling water channels, are slidably sleeved on the outer ring of the corresponding cooling water channels, and are plugged and installed inside the condenser, and the condenser cools the telescopic cooling blocks;

[0038] A first fixing plate, fixed to a side wall of the condenser;

[0039] a second motor, fixed to the top of the first fixing plate;

[0040] A rack fixed to the top of the telescopic cooling block;

[0041] A gear is rotatably mounted on the bottom of the first fixing plate, the second motor drives the gear to rotate via an output shaft, and the rack is meshed with the gear;

[0042] After the second motor is started, it can drive the gear to rotate through the output shaft. After the gear rotates, it drives the rack meshing with it to move. When the rack moves, it drives the telescopic cooling block to move synchronously, so that the part of the cooling water channel located outside the condenser is cooled by the moved telescopic cooling block, while the part of the cooling water channel located inside the condenser maintains the cooling effect under the action of the condenser, which is beneficial to further cool the cooling water inside the cooling water channel, thereby improving the cooling effect of the cooling water by reducing the temperature of the cooling water.

[0043] Preferably, the temperature raising component comprises:

[0044] A plurality of heating wires are respectively inserted into the interior of each of the cooling water channels, and the power connection ends of the heating wires penetrate through the cooling water channels and then extend out;

[0045] A plurality of control boxes are arranged in a linear array and fixedly connected to each other, the control boxes at both ends are fixed inside the box body, and each of the control boxes controls the heating temperature of each of the heating wires respectively;

[0046] The control box can control the power supply of the heating wire and the heating temperature of the heating wire, so that the cooling water can be heated when passing through the heating wire, which helps to avoid the cooling water temperature being too low, causing excessive cooling temperature difference, and causing deformation defects of the grid membrane production line.

[0047] Preferably, the synchronous cooling assembly further comprises:

[0048] A plurality of drive boxes are arranged corresponding to the cooling water channels one by one and are respectively fixedly connected to the middle of each cooling water channel, and the drive box is located between the cooling auxiliary component and the heating component;

[0049] A plurality of impellers are rotatably mounted inside each of the drive boxes through a support frame;

[0050] A plurality of installation boxes are respectively fixed inside each of the drive boxes, a space for the cooling water to pass through is reserved between the installation boxes and the inner wall of the drive box, and the installation boxes are in communication with the external environment of the drive box;

[0051] A plurality of third motors are respectively fixed inside each of the installation boxes, and each of the third motors drives each of the impellers to rotate through an output shaft;

[0052] After the third motor is started, the output shaft drives the impeller to rotate, and the rotation of the impeller can drive the cooling water. By controlling the driving speed of the third motor on the impeller, the flow speed of the cooling water can be controlled, thereby adjusting the cooling speed of the cooling water channel by the cooling water by controlling the flow speed of the cooling water, thereby adjusting the cooling temperature of the grid membrane;

[0053] The installation box is arranged so that the cooling water can cool down the third motor inside the installation box when passing through, thereby helping to avoid the overheating of the third motor when working in a closed environment.

[0054] Preferably, it also includes:

[0055] Two sets of second fixing plates are respectively fixed to opposite ends of the box body at both ends;

[0056] Two second rotating rollers are rotatably mounted between two sets of the second fixing plates respectively;

[0057] a fourth motor, fixed on a side wall of one of the second fixing plates, and the fourth motor drives one of the second rotating rollers to rotate via an output shaft;

[0058] An extrusion conveyor belt is installed on the outer rings of the two second rotating rollers, the extrusion conveyor belt is transmitted through the entire box body, and the portion of the extrusion conveyor belt passing through the box body is located between the grid film and the upper cooling belt;

[0059] After the fourth motor is started, the output shaft drives the second rotating roller connected thereto to rotate. After the second rotating roller rotates, it drives the extrusion conveyor belt to transmit, so that the extrusion conveyor belt passes between the grid membrane and the cooling belt above at the same speed as the transmission speed of the grid membrane. The extrusion conveyor belt and the conveyor belt have the same material and thickness, so that the upper and lower surfaces of the grid membrane are both separated by the extrusion conveyor belt or the conveyor belt between the cooling belt. Therefore, when the temperature of the cooling belt is the same, the cooling effect of the cooling belt on the grid membrane is the same, which is beneficial to more precise temperature control of the upper and lower surfaces of the grid membrane, thereby helping to reduce deformation defects of the grid membrane caused by asynchronous cooling of the upper and lower surfaces.

[0060] Preferably, it also includes:

[0061] A scraper plate is fixed on the side wall of the second fixing plate, and the scraper plate is located at one end where the grid film is transported out of the box body;

[0062] A curved section is integrally formed at one end of the scraper plate facing the extrusion conveyor belt, and an end of the curved section is in scraping contact with the surface of the extrusion conveyor belt;

[0063] When the mesh film is cooled and formed by the clamping action, in order to prevent the mesh film from being attached to the surface of the extrusion conveyor belt after cooling and forming, and affecting the transmission and unloading of the material as the extrusion conveyor belt separates from the conveyor belt, the scraper plate is set. When the mesh film is conveyed to the end of the extrusion conveyor belt, if the mesh film can automatically separate from the extrusion conveyor belt and be unloaded with the conveyor belt, the scraper plate is not needed. If the mesh film cannot automatically separate from the extrusion conveyor belt, the scraper plate is used to scrape the mesh film to separate it, which is helpful to assist the separation of the mesh film and improve the unloading stability of the mesh film.

[0064] By setting the curved section, a buffer distance is provided for the automatic detachment of the grid film, so that the grid film can automatically detach within this distance, which helps to avoid the grid film being damaged by the scraping of the scraper plate.

[0065] Preferably, it also includes:

[0066] A speed sensor is installed on the outer wall of the box at the end, and is used to detect the transmission speed of the grid membrane;

[0067] The speed sensor can detect the transmission speed of the grid membrane. After detecting the transmission speed of the grid membrane, the cooling belt and the extrusion conveyor belt are controlled to maintain synchronous transmission with the grid membrane, thereby helping to avoid the friction between the grid membrane and the cooling belt and the extrusion conveyor belt caused by the transmission speed difference, which may cause the grid membrane to be damaged by the friction.

[0068] Compared with the prior art, the present invention has the following beneficial effects:

[0069] The present invention enables synchronous cooling of the upper and lower surfaces through the provision of a synchronous cooling component. On the one hand, the synchronous cooling of the upper and lower sides is beneficial to increasing the cooling speed of the grid membrane. On the other hand, the synchronous cooling of the upper and lower sides is beneficial to avoiding the uneven cooling temperature of the upper and lower sides of the grid membrane, thereby causing deformation defects of the grid membrane during the cooling and shaping process.

DETAILED DESCRIPTION

[0080] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0081] like Figures 1 to 9 The cooling and shaping equipment for producing a mesh film shown comprises a conveyor belt 1 and also comprises:

[0082] A plurality of boxes 2 are arranged in a linear array, and a conveyor belt 1 drives a grid film 3 to pass through each box 2 in sequence;

[0083] A plurality of synchronous cooling components are installed inside each box 2, respectively, and the cooling temperature of each synchronous cooling component gradually decreases along the conveying direction of the conveyor belt 1;

[0084] The synchronous cooling assembly includes two cooling belts 4, which cool and shape the top and bottom surfaces of the mesh film 3 respectively, and the two cooling belts 4 are synchronously transmitted with the mesh film 3;

[0085] The top surface of the cooling belt 4 located below is in contact with the bottom surface of the conveyor belt 1;

[0086] The conveyor belt 1 and the cooling belt 4 are both conveyor belts made of heat-conducting materials;

[0087] For a mesh film with a certain thickness, since the mesh film is transported by a conveyor belt before being formed after production, the bottom of the mesh film is attached to the conveyor belt. Therefore, when the mesh film is cooled and formed, since the bottom of the mesh film is in contact with the conveyor belt, the mesh film can only be cooled from the upper surface downwards during cooling, so that the lower surface of the mesh film cools slowly during cooling, and deformation defects occur due to uneven cooling speed during cooling and forming of the mesh film.

[0088] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: after the production and molding of the grid film is completed, it is conveyed by the conveyor belt 1, so that the conveyor belt 1 drives the grid film 3 to pass through each box 2 in turn. The synchronous cooling component arranged inside the box 2 can synchronously cool and shape the upper and lower surfaces of the grid film 3 through the two cooling belts 4 arranged, so that the grid film 3 can be synchronously cooled on the upper and lower surfaces during the cooling process. On the one hand, the synchronous cooling of the upper and lower sides is conducive to improving the cooling speed of the grid film 3. On the other hand, the synchronous cooling of the upper and lower sides is conducive to avoiding the uneven cooling temperature of the upper and lower sides of the grid film 3, thereby causing the grid film 3 to produce deformation defects during the cooling and shaping process.

[0089] In addition, during the cooling and shaping process of the grid film 3, the lower surface is supported by the conveyor belt 1 and the lower cooling belt 4, and the upper surface is supported by the upper cooling belt 4, so that during the cooling process of the grid film 3, the upper and lower surfaces are supported synchronously, which plays a clamping role for the grid film 3, so that before the grid film 3 is completely cooled and shaped, the upper and lower surfaces have no space for deformation and curling under the clamping effect, and the grid film 3 remains in a straight state until it is completely cooled and shaped, which is conducive to avoiding the deformation defect of the grid film 3 caused by uneven cooling during the cooling and shaping process;

[0090] The cooling belt 4 is conveyed synchronously with the grid film 3, so that the cooling belt 4 maintains the same speed as the grid film 3 and the conveyor belt 1 during the cooling process, so that the cooling belt 4 is helpful to avoid friction with the grid film 3 during the process of cooling the grid film 3, which may cause the grid film 3 to be damaged due to friction.

[0091] As an optional embodiment, the synchronous cooling component further includes:

[0092] Two groups of first rotating rollers 401, two first rotating rollers 401 form one group, the two groups of first rotating rollers 401 are symmetrically mounted inside the box 2, and the two cooling belts 4 are respectively driven and mounted on the outer rings of the two groups of first rotating rollers 401;

[0093] Two first motors 402 are fixedly mounted on the side wall of the box body 2, and the two first motors 402 respectively drive one of the two groups of first rotating rollers 401 to rotate;

[0094] Two cooling water guide components are respectively installed on the inner rings of the two cooling belts 4 to evenly circulate and cool the cooling belts 4;

[0095] After the first motor 402 is started, it drives the first rotating roller 401 to rotate through the output shaft. After the first rotating roller 401 rotates, it drives the cooling belt 4 to drive, so that the driven cooling belt 4 cools and shapes the grid film 3;

[0096] The cooling water guide assembly can circulate and cool the two cooling belts 4, so that the two cooling belts 4 are in contact with the grid film 3 or the conveyor belt 1 after cooling, so that the cooling belts 4 cool and shape the grid film 3, or the cooling belts 4 cool the conveyor belt 1, and the conveyor belt 1 cools and shapes the grid film 3, which is conducive to cooling and shaping the upper and lower sides of the grid film 3 synchronously;

[0097] After the cooling belt 4 passes through the position for cooling and shaping the grid membrane 3, the cooling water guiding assembly cools the cooling belt 4 so that when the cooling belt 4 is again transmitted to the position for cooling and shaping the grid membrane 3, the cooling belt 4 can be cooled again, thereby cooling and shaping the cooling belt 4.

[0098] As an optional embodiment, the cooling water guide assembly includes:

[0099] The condenser 502 is fixed inside the housing 2 and passes through the inner circle of the cooling belt 4;

[0100] A plurality of cooling water channels 5 are arranged in a linear array, both ends of all cooling water channels 5 are respectively connected to both sides of the condenser 502, and the cooling water channels 5 are filled with cooling water, and the cooling water is cooled when passing through the condenser 502;

[0101] A plurality of paving grooves 501 are respectively formed on the outer walls of the two first rotating rollers 401. When the first rotating rollers 401 rotate, the paving grooves 501 make way for the cooling water channel 5.

[0102] The condenser 502 can cool the cooling water passing through, so that the cooling water inside the cooling water channel 5 can be cooled when passing through the condenser 502, so that the cooling water after cooling can cool the cooling water channel 5. The cooling water channel 5 is made of heat-conducting material, so that the cooling water channel 5 can cool the cooling belt 4 after cooling, so as to achieve cooling of the cooling belt 4;

[0103] The make way groove 501 can make way for the cooling water channel 5 so that the cooling water channel 5 passes through the make way groove 501 when the first rotating roller 401 rotates, so that the cooling water channel 5 can repeatedly contact and cool the cooling belt 4, which is beneficial to improving the cooling efficiency of the cooling belt 4.

[0104] As an optional embodiment, the synchronous cooling component further includes:

[0105] Two groups of temperature sensors 9, two temperature sensors 9 form a group, and both are fixed inside the box 2;

[0106] Two groups of temperature sensors 9 are respectively located at the two ends of the two cooling belts 4 facing the grid membrane 3, and detect the temperature of the grid membrane 3 when the cooling belt 4 starts cooling the grid membrane 3 and when the cooling ends.

[0107] A plurality of cooling auxiliary components are arranged one by one corresponding to the cooling water channels 5, and are respectively used to further cool the cooling water inside each cooling water channel 5;

[0108] A plurality of heating components are arranged one by one corresponding to the cooling water channels 5, and are respectively used to heat the cooling water inside each cooling water channel 5, and the cooling water cools the grid membrane 3 after passing through the cooling auxiliary component and the heating component in sequence;

[0109] The temperature sensor 9 can detect the temperature when the cooling belt 4 starts to cool and form the mesh film 3 and the temperature when the cooling belt 4 ends to cool and form the mesh film 3, so that the temperature when the cooling belt 4 starts to cool and form the mesh film 3 is the same as the temperature when the cooling belt 4 in the previous box 2 ends to cool and form the mesh film 3, so that the cooling temperatures inside each box 2 are connected to each other, thereby avoiding the situation where the mesh film 3 is excessively deformed and causes deformation defects due to excessive temperature difference during cooling;

[0110] When it is detected that the temperature of the cooling belt 4 is too low when it finishes cooling and molding the mesh film 3, resulting in a large cooling temperature difference with the previous box 2, the temperature raising component is controlled to raise the temperature of the cooling water in the cooling water channel 5, so that the temperature of the cooling belt 4 when it starts to cool and mold the mesh film 3 rises, thereby helping to reduce the cooling temperature difference when the cooling belt 4 in each box 2 cools and molds the mesh film 3;

[0111] When it is detected that the temperature of the cooling belt 4 is too high when it finishes cooling and molding the grid membrane 3, the cooling and molding temperature of the grid membrane 3 is too high, which will cause the cooling efficiency of the grid membrane 3 to decrease. At this time, the cooling auxiliary component is controlled to start, so that the cooling auxiliary component cools the cooling water inside the cooling water channel 5 again, so that the temperature of the cooling belt 4 when it starts to cool and mold the grid membrane 3 is reduced, which is beneficial to improve the cooling efficiency of the grid membrane 3.

[0118] After the second motor 602 is started, it can drive the gear 604 to rotate through the output shaft. After the gear 604 rotates, it drives the rack 603 meshing with it to move. When the rack 603 moves, it drives the telescopic cooling block 6 to move synchronously, so that the part of the cooling water channel 5 located outside the condenser 502 is cooled by the moved telescopic cooling block 6, while the part of the cooling water channel 5 located inside the condenser 502 maintains the cooling effect under the action of the condenser 502, which is beneficial to further cool the cooling water inside the cooling water channel 5, thereby improving the cooling effect of the cooling water by reducing the temperature of the cooling water.

A space for cooling water to pass through is reserved between the installation box 703 and the inner wall of the drive box 701, and the installation box 703 is connected to the external environment of the drive box 701;

[0127] A plurality of third motors 702 are respectively fixed inside each installation box 703, and the third motors 702 drive each impeller 7 to rotate through an output shaft;

[0128] After the third motor 702 is started, the output shaft drives the impeller 7 to rotate. The rotation of the impeller 7 can drive the cooling water. By controlling the driving speed of the third motor 702 on the impeller 7, the flow speed of the cooling water can be controlled, thereby adjusting the cooling speed of the cooling water channel 5 by the cooling water by controlling the flow speed of the cooling water, thereby adjusting the cooling temperature of the grid membrane 3;

[0129] The installation box 703 is provided so that the cooling water can cool down the third motor 702 inside the installation box 703 when passing through, thereby helping to avoid the overheating of the third motor 702 when working in a closed environment.

[0130] As an optional embodiment, it also includes:

[0131] Two sets of second fixing plates 1003 are respectively fixed to opposite ends of the box body 2 at both ends;

[0132] Two second rotating rollers 1001 are rotatably mounted between two sets of second fixed plates 1003;

[0133] The fourth motor 1002 is fixed on the side wall of one of the second fixed plates 1003, and the fourth motor 1002 drives one of the second rotating rollers 1001 to rotate through the output shaft;

[0134] The extrusion conveyor belt 10 is driven and installed on the outer rings of the two second rotating rollers 1001. The extrusion conveyor belt 10 is transmitted through the entire box body 2, and the part of the extrusion conveyor belt 10 passing through the box body 2 is located between the grid film 3 and the upper cooling belt 4;

[0135] After the fourth motor 1002 is started, the second rotating roller 1001 connected thereto is driven to rotate through the output shaft. After the second rotating roller 1001 rotates, it drives the extrusion conveyor belt 10 to be transmitted, so that the extrusion conveyor belt 10 passes between the grid film 3 and the upper cooling belt 4 at the same speed as the transmission speed of the grid film 3. The extrusion conveyor belt 10 and the conveyor belt 1 are made of the same material and thickness, so that the upper and lower surfaces of the grid film 3 are both separated by the extrusion conveyor belt 10 or the conveyor belt 1 between the cooling belt 4, so that when the temperature of the cooling belt 4 is the same, the cooling effect of the cooling belt 4 on the grid film 3 is the same, which is beneficial to more precise temperature control of the upper and lower surfaces of the grid film 3, thereby helping to reduce deformation defects of the grid film 3 caused by asynchronous cooling of the upper and lower surfaces.

[0136] As an optional embodiment, it also includes:

[0137] The scraper plate 11 is fixed on the side wall of the second fixing plate 1003, and the scraper plate 11 is located at one end where the grid film 3 is transported out of the box body 2;

[0138] The curved section 1101 is integrally formed at one end of the scraper plate 11 facing the extrusion conveyor belt 10 , and the end of the curved section 1101 is in scraping contact with the surface of the extrusion conveyor belt 10 ;

[0139] When the mesh film 3 is cooled and formed by the clamping action, in order to prevent the mesh film 3 after cooling and forming from adhering to the surface of the extrusion conveyor belt 10, and affecting the transmission and unloading of materials as the extrusion conveyor belt 10 separates from the conveyor belt 1, the scraper plate 11 is set. When the mesh film 3 is transmitted to the end of the extrusion conveyor belt 10, if the mesh film 3 can automatically separate from the extrusion conveyor belt 10 and be unloaded along with the conveyor belt 1, the scraping of the scraper plate 11 is not required. If the mesh film 3 cannot automatically separate from the extrusion conveyor belt 10, the scraper plate 11 is used to scrape the mesh film 3 to separate it, which is helpful for assisting the separation of the mesh film 3 and improving the unloading stability of the mesh film 3.

[0140] The bending section 1101 is provided to provide a buffer distance for the automatic detachment of the mesh film 3 , so that the mesh film 3 can automatically detach within this distance, thereby facilitating the avoidance of damage to the mesh film 3 caused by the scraping of the scraping plate 11 .

[0141] As an optional embodiment, it also includes:

[0142] A speed sensor is installed on the outer wall of the box body 2 at the end, and is used to detect the transmission speed of the grid membrane 3;

[0143] The speed sensor can detect the transmission speed of the grid membrane 3. After detecting the transmission speed of the grid membrane 3, the cooling belt 4 and the extrusion conveyor belt 10 are controlled to maintain synchronous transmission with the grid membrane 3, thereby helping to avoid the friction between the grid membrane 3 and the cooling belt 4 and the extrusion conveyor belt 10 caused by the transmission speed difference, resulting in the grid membrane 3 being damaged by the friction.

[0144] Working principle of the present invention: after the production and forming of the mesh film is completed, it is conveyed by the conveyor belt 1, so that the mesh film 3 is driven by the conveyor belt 1 to pass through each box 2 in turn. The synchronous cooling component arranged inside the box 2 can synchronously cool the upper and lower surfaces of the mesh film 3 through the two cooling belts 4 arranged, so that the mesh film 3 can be synchronously cooled on the upper and lower surfaces during the cooling process. On the one hand, the synchronous cooling of the upper and lower sides is conducive to improving the cooling speed of the mesh film 3. On the other hand, the synchronous cooling of the upper and lower sides is conducive to avoiding the uneven cooling temperature of the upper and lower sides of the mesh film 3, thereby causing deformation defects of the mesh film 3 during the cooling and shaping process.

[0145] In addition, during the cooling and shaping process of the grid film 3, the lower surface is supported by the conveyor belt 1 and the lower cooling belt 4, and the upper surface is supported by the upper cooling belt 4, so that during the cooling process of the grid film 3, the upper and lower surfaces are supported synchronously, which plays a clamping role for the grid film 3, so that before the grid film 3 is completely cooled and shaped, the upper and lower surfaces have no space for deformation and curling under the clamping effect, and the grid film 3 remains in a straight state until it is completely cooled and shaped, which is conducive to avoiding the deformation defect of the grid film 3 caused by uneven cooling during the cooling and shaping process;

[0146] The cooling belt 4 is conveyed synchronously with the grid film 3, so that the cooling belt 4 maintains the same speed as the grid film 3 and the conveyor belt 1 during the cooling process, so that the cooling belt 4 is helpful to avoid friction with the grid film 3 during the process of cooling the grid film 3, which may cause the grid film 3 to be damaged due to friction.
