At present, the common limit mechanism is to install two limit switches at the top and bottom of the greenhouse to control the stroke of the film roll during operation. However, when installing these limit switches, the staff must climb to the height of the greenhouse, which not only increases the risk of installation, but also makes the operation quite cumbersome when the limit position needs to be adjusted.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0043] Example 1

[0044] Reference Figure 1 , which is the first embodiment of the present invention, provides a film rolling machine, including a limiting unit 100, including a support member 101, a rolling member 102 movably arranged on the outer side of the support member 101, and a stroke member 103 arranged on the inner side of the rolling member 102 and moving synchronously therewith; a winding unit 200, including a winder 201, a winding roller 202 arranged at the output end of the winder 201, and a support sleeve 203 arranged at the other end of the winding roller 202; after the stroke member 103 moves a certain distance, it can control the winder 201 to be fixed at an appropriate position.

[0045] In this embodiment, the support member 101 is a slender rod-shaped structure, and one end of the support member 101 is provided with a spike that can extend into the bottom surface, so that the support member 101 can be stably fixed on the bottom surface; during use, the number of support members 101 is at least two groups; two groups of support members 101 can support and fix both ends of the roller.

[0046] It should be noted that the rolling member 102 can be located outside the support member 101 and slide; during the sliding process of the rolling member 102, the travel member 103 can be driven to move, and the travel member 103 will record the travel distance when moving.

[0047] Furthermore, the winder 201 is fixed on one side of the rolling element 102. When the output end of the winder 201 drives the roller 202 to rotate, the film can be rolled up on the outside of the roller 202. During the winding process of the film, the winder 201 changes as the height of the rolling element 102 changes.

[0048] It should be noted that the support sleeve 203 serves the purpose of supporting the other end of the winding roller 202. The winding roller 202 and the support sleeve 203 are movably connected. As the height of the winder 201 changes, the winding roller 202 can drive the support sleeve 203 to move, so that the support sleeve 203 moves to a suitable position.

[0049] During use, the winder 201 drives the winding roller 202 to rotate, and the winding roller 202 can drive the film to be wound around its outer side while rotating. As the film is wound, the winder 201 will be subjected to an upward force, pulling the winder 201 upward, and the provided rolling member 102 can slide along the outer wall of the support member 101, so that the film can be wound and the position of the winder 201 can be adjusted. Along with the movement of the rolling member 102, the stroke member 103 also records the distance of its movement at the same time. When the film is wound to the appropriate position, the stroke member 103 has a fixed stroke and records this distance. Whenever the stroke member 103 moves to this distance, the winder 201 can be controlled to stop driving, thereby fixing the position of the film winding.

[0050] In summary, the present invention drives the roller to rotate by means of the winder set up, so that the film can be wound around the outside of the roller, and then the height position of the film roll is recorded by the encoder, so as to effectively control the opening and closing of the winder, thereby effectively avoiding the workers from adjusting the limit mechanism to obtain the position when working at high places, thereby ensuring the working safety of the workers to a certain extent.

[0051] Example 2

[0052] Reference Figures 1 to 4 , which is a second embodiment of the present invention, includes: the rolling member 102 includes a connecting sleeve 102a, and a roller 102b arranged between two adjacent groups of connecting sleeves 102a; the roller 102b is rotatable inside the two adjacent groups of connecting sleeves 102a, and the roller 102b is in conflict with the supporting member 101.

[0053] In this embodiment, the connecting sleeve 102a is a quarter rectangular structure, and four groups of connecting sleeves 102a are covered on the outside of the support member 101. The setting of the connecting sleeve 102a can support the roller 102b, ensuring that when the rolling member 102 drives the winder 201 to adjust its position, rolling friction instead of sliding friction can better facilitate the movement of the winder 201.

[0054] It should be noted that the roller 102b is in conflict with the outer wall of the support member 101, so that the rolling member 102 can be moved more simply and conveniently, and the force required by the reel 201 during the reeling process can be reduced.

[0055] Furthermore, the travel member 103 includes a rotating rod 103a, an encoder 103b arranged on the outside of the rotating rod 103a, and a locking sleeve 103c arranged at the end of the encoder 103b; the rotating rod 103a passes through the side wall of the connecting sleeve 102a and extends to its outside, and the rotating rod 103a is rotatable inside the connecting sleeve 102a; the end of the locking sleeve 103c can be tightly attached to the side wall of the connecting sleeve 102a, thereby realizing the limitation of the rotating rod 103a.

[0056] It should be noted that the rotating rod 103a is connected to the encoder 103b, and an internal thread structure is provided inside the rotating rod 103a; and the locking sleeve 103c is provided with an external thread structure compatible with the rotating rod 103a; the locking sleeve 103c is threadedly connected to the rotating rod 103a, and after the locking sleeve 103c is threadedly fed along the rotating rod 103a for a certain distance, the end of the locking sleeve 103c can contact and press the surface of the connecting sleeve 102a; then the position of the rotating rod 103a can be fixed.

[0057] Furthermore, the encoder 103b includes a connecting plate 103b-1 for connecting to the rotating rod 103a, and a running wheel 103b-2 arranged at the output end of the encoder 103b; the connecting plate 103b-1 is located between the two sets of connecting sleeves 102a, and the running wheel 103b-2 is in conflict with the outer wall of the support member 101.

[0058] It should be noted that the rotating rod 103a and the connecting plate 103b-1 are interference fit, so that the rotation of the rotating rod 103a can drive the encoder 103b connected to the connecting plate 103b-1; at the same time, when driving the vehicle, the walking wheel 103b-2 is connected to the output end of the encoder 103b, and the rotation of the walking wheel 103b-2 can enable the encoder 103b to convert the rotation displacement signal into a periodic electrical signal, thereby transmitting the signal.

[0059] Specifically, the running wheel 103b - 2 adopts a tire structure. During the movement of the rolling element 102 , as the encoder 103b moves in height, the running wheel 103b - 2 can be driven to flip along the outer wall of the support element 101 to a certain extent.

[0060] Furthermore, the number of the supporting members 101 is two groups, and the number of the rolling members 102 corresponds to that of the supporting members 101 ; the winder 201 is installed on one side of one group of the rolling members 102 ; and the connection end D1 of the winding roller 202 is connected to the output end of the winder 201 .

[0061] It should be noted that a fixing frame is provided on one side of the rolling element 102 , and the fixing frame can provide a stable installation position for the winder 201 , so that the movement of the winder 201 during the winding process can drive the rolling element 102 to move.

[0062] Furthermore, a support sleeve 203 is arranged outside the limit end D2 of the roller 202 ; the support sleeve 203 includes a bearing 203a arranged inside thereof, and a connecting rod 203b arranged on the outer wall of the support sleeve 203 ; the connecting rod 203b is connected to one set of rolling elements 102 .

[0063] It should be noted that the other end of the roller 202 passes through the support sleeve 203 and extends to the outside thereof, in order to further ensure that there is no separation between the roller 202 and the support sleeve 203; a baffle is also provided at the end of the roller 202; the roller 202 can be fixed to the inner side of the support sleeve 203 through the baffle.

[0064] Specifically, the support sleeve 203 can be provided to support the end of the winding roller 202 so that the winding roller 202 can rotate normally; during the rotation process, the winding roller 202 can be driven to complete the winding of the film.

[0065] Preferably, the end of the winding roller 202 passes through the interior of the bearing 203a, and the bearing 203a can better facilitate the rotation of the winding roller 202, so that the winder 201 can save more effort in the process of driving the winding roller 202 to rotate.

[0066] Example 3

[0067] Reference Figures 1 to 4 , which is the third embodiment of the present invention, includes that the rolling member 102 also includes a sleeve rod with an annular structure, and a ball is also arranged inside the sleeve rod, and the ball can conflict with the outer wall of the support member 101.

[0068] In this embodiment, the sleeve rod is sleeved on the outside of the support member 101, and there is a certain gap between the sleeve rod and the support member 101; at the same time, a movable ball is provided on the inner wall of the sleeve rod, the ball protrudes from the inside of the support member 101, and the ball can contact the outer wall of the support member 101.

[0069] It should be noted that the support member 101 can be a circular or rectangular structure, the structure of the sleeve rod is compatible with the support member 101, and the outer wall of the support member 101 has a surface that contacts the ball; thereby ensuring that the rolling member 102 can slide up and down along the outer wall of the support member 101.

[0070] Furthermore, the travel member 103 includes a rotating rod 103a, an encoder 103b disposed outside the rotating rod 103a, and an elastic member disposed outside the rotating rod 103a;

[0071] In this embodiment, the rotating rod 103a and the encoder 103b can be connected and fixed by bolting; thereby ensuring that the rotating rod 103a and the encoder 103b can rotate synchronously; and the reset member set can use a torsion spring to push the encoder 103b to flip a certain angle; the elastic potential energy released by the reset member can push the encoder 103b to contact the outer wall of the support member 101, thereby ensuring that the encoder 103b can rotate while moving.

[0072] Furthermore, the encoder 103b includes a connecting plate 103b-1 for connecting to the rotating rod 103a, and a walking wheel 103b-2 provided at the output end of the encoder 103b.

[0073] It should be noted that the walking wheel 103b-2 can also adopt a spherical structure, and the walking wheel 103b-2 can slide along the outer wall of the support 101 during rotation; the spherical structure makes the walking wheel 103b-2 and the support 101 point contact, so that the walking wheel 103b-2 can still rotate while the contact area between the walking wheel 103b-2 and the support 101 is small.

[0074] Furthermore, a support sleeve 203 is provided outside the limiting end D2 of the winding roller 202; the support sleeve 203 may be a tubular structure with a hollow interior, and the winding roller 202 is located inside the support sleeve 203 and can rotate.

[0075] It should be noted that the support sleeve 203 is connected to another set of rolling elements 102 , and the rolling elements 102 can slide along the outer wall of the support element 101 to drive the height of the roller 202 to be continuously adjusted.

[0076] Example 4

[0077] Reference Figure 5 , which is the fourth embodiment of the present invention, and this embodiment further provides a control system; a control mainboard, including a single-chip microcomputer, a wireless communication module, an encoder data acquisition interface, a status monitoring module, a film winder interface, and an external power supply interface; the encoder 103b is connected to the control mainboard through the encoder data acquisition interface; the winder 201 is connected to the control mainboard through the film winder interface.

[0078] The control motherboard is the central part of the entire system, responsible for coordinating and managing the work of other modules.

[0079] The film winder is connected to the control main board via a film winder interface; the film winder is used to handle the winding operation of the film material.

[0080] The status monitoring module is connected to the control main board through the corresponding interface; the module is responsible for monitoring the status of various devices in the system and transmitting data to the control main board for analysis and processing.

[0081] The wireless communication module communicates wirelessly with an external network or other devices via an antenna; it can receive or send data to the control mainboard wirelessly.

[0082] The external power interface provides power support for the entire system; it can be connected to an external power source to ensure normal operation of the system.

[0083] The encoder is connected to the control main board through the encoder data acquisition interface; the encoder is used to measure the position, speed and other information of the mechanical movement, and convert it into electrical signals and transmit it to the control main board for processing.

[0084] As the core processor, the microcontroller executes instructions inside the control motherboard and coordinates the workflow between various modules.

[0085] In this embodiment, when the electric film winder is running, the encoder drives the running wheel 103b-2 to rotate, and the running wheel 103b-2 rotates synchronously with the encoder 103b; the encoder converts the rotation displacement signal into an electrical signal and transmits it to the control mainboard.

[0086] The encoder principle converts the displacement signal of the film winder into a periodic electrical signal, and then converts this electrical signal into a counting pulse, using the number of pulses to represent the size of the displacement.

[0087] Specifically, the control main board is connected to the encoder and the film rolling machine, and the electrical signal transmitted by the encoder is analyzed into the displacement length of the film rolling machine. It is judged whether the set length is reached. If the set length is reached, a control instruction is issued to the film rolling machine.

[0088] It should be noted that when adjusting the limit of the film winder, first roll the film winder down to the appropriate lower limit, click the learning button of the control main board, and record the displacement length required to reach the lower limit; then start the film winder motor to let it roll up, and when it reaches the appropriate upper limit, click the learning button of the control main board to record the displacement length required to reach the upper limit; the control main board records the respective displacement lengths of the upper and lower limits, and the limit adjustment is completed.

[0089] Specifically, when the film rolling motor rotates, the encoder is driven to rotate through the walking wheel 103b-2. The encoder converts the film rolling displacement signal into an electrical signal, which is transmitted to the control main board through the signal line. The control main board interprets the electrical signal as the film rolling running displacement length, and compares it with the set film rolling running length. If the specified length is reached, a stop command is issued to the film rolling motor.
