[0002] Tents are mostly made of canvas. Together with the supporting things, they can be disassembled and transferred at any time. Tents are carried in the form of components and assembled on site. Therefore, various components and tools are required. Among them, the vertical pole is one of the necessary components for tent erection and support.

[0003] Currently, in the production process of collapsible tent support poles, traditional manufacturing equipment often has problems such as poor versatility, low processing accuracy, and low automation. For example, for support pole materials of different sizes, it is difficult for traditional equipment to perform flexible clamping and conveying, resulting in low production efficiency; during the shrinking process, due to the lack of effective fixing devices, the support poles are prone to bending deformation, affecting product quality. At the same time, the function of this kind of shrinking equipment is relatively single, and the support poles can only be cut by other equipment and then shrunk, which will increase labor costs and equipment costs. Summary of the Invention

[0008] By adopting the above technical solution, the setting of the first belt transmission device provides power for the rotation of the roller, enabling the smooth conveying of the support rod material; through the cooperation of the bidirectional screw and the screw nut head, the position of the roller can be accurately adjusted, so as to adapt to the clamping and conveying of support rod materials of different sizes.

[0009] Preferably, a plurality of limiting plates for limiting and guiding are movably penetrated through both sides of the outer ring surface of one of the rollers. A fixed vertical plate fixedly connected to the cabinet is fixedly arranged on one side of the plurality of limiting plates. An arc-shaped groove for guiding and limiting the roller is penetrated through the fixed vertical plate.

[0010] By adopting the above technical solution, the limiting plates play a role in limiting and guiding the bidirectional screw, ensuring the stability of the rotation of the bidirectional screw; the arc-shaped groove on the fixed vertical plate further guides and limits the movement of the roller, enabling the roller to move along a predetermined track during the adjustment process.

A rack slidably arranged on the support platform plate is meshed with one side of the straight gear. A tube shrinking device for shrinking the material into a tube is fixedly arranged on one side of the rack far from the straight gear.

[0014] By adopting the above technical solution, the synchronous motor drives the threaded rod to rotate through the second belt transmission device, and then the spur gear is engaged with the rack to realize the linear motion of the pipe shrinking device, so as to form the pipe shrinking of the material.

[0015] Preferably, a cross plate which is slidably arranged on the outer ring surface of the limiting vertical rod and is threadedly connected with the threaded rod to realize longitudinal movement is provided. A plurality of vertically sliding rods with the same structure and symmetrically arranged are movably penetrated through the cross plate. At one end of the plurality of vertically sliding rods far away from the cross plate, a pipe pressing plate for abutting and fixing the support rod material is fixedly arranged.

[0016] By adopting the above technical solution, the rotation of the threaded rod drives the cross plate to move longitudinally. The arrangement of the vertically sliding rods and the pipe pressing plate can abut and fix the support rod material, prevent the material from moving during the pipe shrinking process, and ensure the accuracy of the pipe shrinking forming.

[0017] Preferably, compression springs are sleeved on the outer ring surfaces of one ends of the plurality of vertically sliding rods far away from the cross plate. One ends of the plurality of compression springs are fixedly connected with the pipe pressing plate, and the other ends of the plurality of compression springs are fixedly connected with the cross plate to realize buffering and resetting of the pipe pressing plate.

[0018] By adopting the above technical solution, the arrangement of the compression springs plays a buffering role, can reduce the impact force of the pipe pressing plate on the material, and avoid damage to the material during the fixing process.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By utilizing the cooperation of the bidirectional lead screw and the lead screw nut head, the distance between the rollers can be easily adjusted to adapt to support rod materials of different sizes. This clamping method reduces the time for replacing fixtures or adjusting the production line, improving production efficiency. At the same time, the linkage of the first belt transmission device and the conveying device ensures the smooth and continuous conveyance of the support rod material, further enhancing the fluency of the production line; 2. With the cooperation of the threaded rod, spur gear, and rack, precise movement of the pipe shrinking device is achieved.

Detailed implementation manners

[0028] The following will further elaborate on the present application with reference to the Figures 1-8 accompanying drawings.

[0029] The embodiment of the present application discloses an integrated device for shrinking and cutting a folding tent support rod.

[0030] Referring to Figures 1-5 , an integrated device for shrinking and cutting a folding tent support rod includes a cabinet 100 located on the ground and a conveying device 101 for transporting the manufacturing material (aluminum alloy round tube) of the tent support rod. The conveying device 101 uses a conveyor belt for transmission, and a limiting and guiding channel composed of several horizontal bars is arranged above the conveyor belt to guide the support rod pipe material. A rotary adjustment mechanism 200 is arranged on one side of the conveying device 101, and the rotary adjustment mechanism 200 is used for clamping support rod materials of different sizes and conveying them into the device.

[0031] Referring to Figures 1-5, the rotation adjustment mechanism 200 includes a first belt drive device 201 rotatably provided on both sides at one end of the conveying device 101. The first belt drive device 201 is composed of a number of belt pulleys with the same structure and belts that are slidably clamped to each other. The number of belt pulleys is set to be greater than two, and three are optimally set in this device. The three belt pulleys are distributed in a triangular shape. One of the belt pulleys is fixedly connected to the roller at one end of the conveying device 101. Thus, when the roller of the conveying device 101 rotates, it can drive the belt pulley fixedly connected to the roller to rotate. Note: In the following text, the belt pulley fixedly connected to the roller in the first belt drive device 201 will be referred to as the first belt pulley, and the remaining two will be referred to as the second belt pulleys.

[0032] Refer to Figure 5 , the remaining two belt pulleys are respectively fixedly connected to a number of rollers 206 with the same structure. The number of rollers 206 is set to be greater than two, and two are optimally set in this device to match the rollers 206. A fixed shaft is provided in the middle of the two rollers 206, and the fixed shaft passes through the two second belt pulleys in the first belt drive device 201, and is movably penetrated through the fixed vertical plate 207 fixedly provided at the upper part of one end of the cabinet 100. At the same time, it is rotatably provided in the middle of a number of screw nut heads 202 slidably provided on the side of the fixed vertical plate 207 away from the first belt drive device 201. The number of screw nut heads 202 is the same as the number of rollers 206, and the two screw nut heads 202 are located on the same vertical axis and are both vertically threaded through by the double screw rod 203 along the axis.

[0033] Refer to Figure 5 , at the same time, a handle is fixedly provided on the upper part of the double screw rod 203 to drive the double screw rod 203 to rotate. A tightening knob is provided on the side of one of the screw nut heads 202, so as to abut and limit the double screw rod 203, forming a fixed relationship between the double screw rod 203 and the screw nut head 202, thereby restricting the rotation of the roller 206. At the same time, the degree of tightening between the tightening knob and the double screw rod 203 can cause a certain damping during the rotation of the double screw rod 203, thereby increasing the rotation effect. An arc-shaped groove 204 is provided in the middle of the vertical surface of the fixed vertical plate 207, and the arc-shaped groove 204 penetrates through the fixed vertical plate 207 and is slidably provided with the fixed shaft passing through the second belt pulley of the first belt drive device 201 in the roller 206 (as Figure 5 shown). Limit plates 205 are fixedly provided at both ends of the fixed vertical plate 207, and the inner cavity of the limit plate 205 is slidably provided with the double screw rod 203. Thus, when the double screw rod 203 drives the screw nut head 202 and the roller 206 to move in the arc-shaped groove 204, the limit plate 205 can play a role in guiding and limiting the double screw rod 203.

[0034] The first pulley in the first belt transmission device 201 is fixedly connected to the roller in the conveying device 101. Thus, when the first belt transmission device 201 rotates, it will drive the first pulley in the first belt transmission device 201 to rotate. At the same time, the two second pulleys in the first belt transmission device 201 are respectively fixedly connected to the two rollers 206. Thus, when the first pulley in the first belt transmission device 201 rotates following the conveying device 101, through the transmission belt, it drives the two second pulleys in the first belt transmission device 201 to rotate synchronously, thereby driving the two rollers 206 fixedly connected thereto to rotate synchronously, realizing the clamping and conveying of the support pipe material.

[0035] The fixed shafts passing through the second pulleys of the first belt transmission device 201 at both ends of the roller 206 are slidably arranged in the arc-shaped grooves 204 opened on the fixed vertical plate 207. At the same time, the fixed shafts on the roller 206 are rotatably connected to the screw nut head 202, and the screw nut head 202 is threadedly penetrated by the bidirectional screw 203. Thus, when the bidirectional screw 203 is rotated, it can drive the screw nut head 202 to move vertically, thereby driving the fixed shafts on the roller 206 to move in the arc-shaped grooves 204. At the same time, under the guiding action of the arc-shaped grooves 204, the positions of the two rollers 206 are adjusted, changing the distance between the two rollers 206, so that the rollers 206 can clamp support pipe materials of different sizes.

[0036] Refer to Figures 3-4 , a number of structure-identical limit blocks 208 are movably penetrated through the outer ring surface of the lower roller 206. And the number of the several limit blocks 208 is greater than two, but in this device, it is optimal to set two, and the two limit blocks 208 are respectively arranged at both ends of the roller 206. And the lower end surfaces of the two limit blocks 208 are fixedly connected to one side of the upper surface of the support table plate 209 arranged in the inner cavity of the cabinet 100, and the lower surface of the end of the support table plate 209 away from the limit blocks 208 abuts against two inclined support rods arranged on the upper side wall of the inner cavity of the cabinet 100 (as Figure 3 shown).

[0037] Refer to Figures 3-4 , a square groove is opened at the middle position of the support table plate 209, and a supporting plate 211 is rotatably arranged in the groove. And one end of the supporting plate 211 away from the limit blocks 208 is rotatably connected to the side wall of the square groove in the middle of the support table plate 209. And a lifting device 210 is arranged at the middle part of the lower surface of the supporting plate 211 on the side of the limit blocks 208 (as Figure 4 shown), and the lifting device 210 is composed of an electric push rod, two structure-identical connecting rods, and a cross bar for guiding and limiting fixedly connected to the bottom surface of the inner cavity of the cabinet 100 (as Figure 3As shown), and the two connecting rods are connected to the bottom surface of the supporting plate 211 through movable seats on the side far from the transfer with the electric push rod. Then, the connecting rods are controlled by the electric push rod in the lifting device 210, so as to realize the rotation of the supporting plate 211 in the square groove in the middle of the supporting platform plate 209, make the supporting plate 211 form an inclined shape, and then enable the processed support rods on the upper part of the supporting plate 211 to move along the slope of the supporting plate 211 to the platform arranged at the lower end of the cabinet 100.

[0038] The two limit blocks 208 are rotatably connected to both ends of one of the rollers 206 and fixedly connected to both sides of the upper surface of the supporting platform plate 209. Then, the limit blocks 208 are stably arranged at both ends of the roller 206 without affecting the rotation of the roller 206. When the roller 206 moves under the guiding action of the arc groove 204, it can drive the limit blocks 208 to move synchronously, drive the supporting platform plate 209 and the supporting plate 211 to move. At the same time, the inclination angle of the inclined support rod arranged on the side wall of the inner cavity of the cabinet 100 far from the limit block 208 is the same as the inclination angle of the arc groove 204. Then, when the limit block 208 drives the supporting platform plate 209 to move, the inclined support rod can play an auxiliary role.

[0039] When the supporting plate 211 moves with the supporting platform plate 209, since the cross bar in the lifting device 210 arranged at its lower part is fixed to the inner cavity of the cabinet 100, but the connecting rod can be adjusted by the electric push rod therein. When the supporting plate 211 is at the lowest point, there is an included angle greater than sixty degrees between the connecting rod and the supporting plate 211. Then, without affecting the supporting performance, there is still a certain rising margin for the connecting rod. At the same time, when the connecting rod is perpendicular to the supporting plate 211 at ninety degrees, the supporting plate 211, the supporting platform plate 209 and the roller 206 rise to the highest point. And a sensor is fixedly arranged at the transfer position of the electric push rod and the connecting rod through a fixture, which is used to sense the change of the connecting rod driven by the movement of the supporting plate 211, so as to control the electric push rod, make the electric push rod push or pull back the connecting rod, and then change the inclination angle of the connecting rod, so that the connecting rod can move with the supporting plate 211.

[0040] It should be noted that the electric push rods and sensors in the conveying device 101, the first belt transmission device 201 and the lifting device 210 are all existing devices, and the electric push rods and sensors need to be connected to the PLC controller. However, since they are all prior arts, their structural principles will not be described in detail here. At the same time, the electric push rod can adopt the Juying series electric push rod to adapt to the Hall sensor, which has a large load capacity and customizable parameters. Adapting the Hall sensor is more suitable for this device. However, since they are all prior arts, they will not be described in detail here.

[0041] Refer to Figure 2 、 Figure 6 、 Figure 7A lower compression tube mechanism 300 is provided on one side of the cabinet 100, and the lower compression tube mechanism 300 is used to squeeze and fix the support tube material to prevent the support tube material from bending and deformation during the tube shrinking process, and the lower compression tube mechanism 300 includes a limit rod 301 with a smooth surface fixedly provided on one side of the support table 209, and an end of the limit rod 301 away from the support table 209 is fixedly connected to one end of a horizontal fixing plate 302, and the length of the horizontal fixing plate 302 spans the entire support table 209, and the horizontal fixing plate 302 is away from the limit rod. A threaded rod 305 is movably provided at one end of 301, and is fixedly connected to one of the pulleys of the second belt transmission device 304 on the end face where the threaded rod 305 passes through the horizontal fixed plate 302. The second belt transmission device 304 is composed of two pulleys and a belt, and in addition to the pulley fixed to the threaded rod 305, the other pulley is fixedly connected to the output end of the synchronous motor 303 fixedly arranged in the middle of the upper surface of the horizontal fixed plate 302, so that the second belt transmission device 304 transmits the power of the synchronous motor 303 to the threaded rod 305.

[0042] Reference Figure 2 , Figure 7 The threaded rod 305 is rotatably connected and limited to the support table 209 at one end away from the second belt transmission device 304, and the threaded rod 305 is fixed at the end connected to the support table 209 and passes through the middle of the spur gear 306, so that the spur gear 306 rotates synchronously with the threaded rod 305 on the support table 209, and a rack 307 is meshed on one side of the spur gear 306, and the lower surface and side surface of the rack 307 are slidably connected to the upper surface of the support table 209 and the side surface of the supporting plate 211, and a shrinking device 308 is fixedly provided on the side surface of the end of the rack 307 away from the spur gear 306, and the inner cavity of the shrinking device 308 is provided with an inclined surface for changing the diameter of the support rod (such as Figure 6 As shown), when the spur gear 306 drives the rack 307 to move, the rack 307 can drive the tube shrinking device 308 to be plugged into the support rod, and under the action of the inclined surface of the tube shrinking device 308, the diameter of one end of the support rod is changed to complete the tube shrinkage of the support rod.

[0043] It should be noted that the pipe shrinking device 308 is connected to the rack 307 by bolts, which facilitates the replacement of the pipe shrinking device 308. At the same time, the depth and diameter of the pipe shrinking device 308, as well as whether to add a heating wire in the pipe shrinking device 308, can all be customized according to actual needs. At the same time, the synchronous motor 303 needs to be connected to the PLC controller. However, since it is an existing technology, and the synchronous motor 303 can select the TYCT5 series permanent magnet assisted synchronous reluctance motor of Xiangda Motor, and the compression spring 312 can adopt the calculation formula of the alloy yellow single spring: F = kx, where F is the external force received by the spring, unit: N; k is the stiffness coefficient of the spring, unit: N / m; x is the deformation of the spring, unit: m. Then calculate the compression elastic force of the alloy spring so that it can be used in this device. However, since they are all existing equipment, their structural principles will not be elaborated here too much.

[0044] Several horizontal bars are arranged on the upper part of the conveying device 101, and the distance between several horizontal bars is greater than the diameter of the support rod, so that several horizontal bars can limit the support rod. And the distance between several horizontal bars and the semi-circular groove arranged at the lower end of the pipe pressing plate 311 are on the same axis, so that the support rod can be initially limited, and when it moves to the lower end of the pipe pressing plate 311, it can be initially aligned with the semi-circular groove arranged at the lower part of the pipe pressing plate 311, preventing it from being scattered and affecting the extrusion effect of the pipe pressing plate 311. At the same time, the semi-circular groove arranged at the lower end of the pipe pressing plate 311 and the opening of the pipe shrinking device 308 are on the same axis. Then when the pipe pressing plate 311 limits and extrudes and fixes the support rod, the opening at one end of the support rod can be aligned with the opening of the pipe shrinking device 308, so that the pipe shrinking device 308 can accurately shrink and form the support rod.

[0045] Since one of the pulleys of the output end of the synchronous motor 303 is fixedly connected to the second belt transmission device 304, and the other pulley in the second belt transmission device 304 is fixedly connected to the threaded rod 305 movably penetrating through one side of the horizontal fixed plate 302, when the output end of the synchronous motor 303 rotates, it can drive the second belt transmission device 304 to transmit power to the threaded rod 305, so that the synchronous motor 303 can drive the threaded rod 305 to rotate on the horizontal fixed plate 302 through the second belt transmission device 304. When the threaded rod 305 rotates, it will drive the spur gear 306 fixedly arranged at one end of its rotationally arranged connection with the support platform plate 209 to rotate synchronously. When the spur gear 306 rotates, it will drive the rack 307 meshed on one side of it to move, so that the rack 307 drives the pipe shrinking device 308 to move synchronously and insert into one end of the support rod, and uses the inclined plane arranged in the pipe shrinking device 308 to change the diameter of the support rod, thereby realizing the pipe shrinking operation of the support rod. At the same time, the length of the rack 307 is less than half of the inner cavity length of the cabinet 100, so that the rack 307 can move normally on the surface of the support platform plate 209. And a auxiliary cross bar is fixedly arranged on the side of the pipe shrinking device 308 away from the rack 307, and a T-shaped slide bar (as Figure 6 shown) is arranged at the lower end of the cross bar, and a T-shaped chute of the same size is opened on the support platform plate 209 at the same position of the T-shaped slide bar, thereby realizing the limiting and guiding effects on the pipe shrinking device 308.

[0046] Referring to Figure 2 , Figure 7 , a cross plate 309 is movably penetrated through the outer ring surface of the limit vertical rod 301, and the cross plate 309 longitudinally slides on the outer ring surface of the limit vertical rod 301. At the same time, one end of the cross plate 309 away from the limit vertical rod 301 is threadedly penetrated through the threaded rod 305, so that the cross plate 309 can longitudinally move under the rotation of the threaded rod 305. And a plurality of vertical slide bars 310 are movably penetrated through the cross plate 309, and the structures of the plurality of vertical slide bars 310 are the same. The number of the plurality of vertical slide bars 310 is more than two, but it is optimal to set four in this device, and they are respectively arranged at the four corners of the cross plate 309 (as Figure 7As shown in the figure, at one end of the four vertical sliding rods 310 away from the cross plate 309, it is fixedly connected to the upper surface of the vertical sliding rod 310. And on the outer ring surface of the end of the vertical sliding rod 310 fixedly connected to the pressure pipe plate 311, a compression spring 312 is sleeved. One end of the compression spring 312 is fixedly connected to the upper surface of the pressure pipe plate 311, and the other end is fixedly connected to the lower surface of the cross plate 309, thus realizing the limiting and buffering effects on the cross plate 309 and the pressure pipe plate 311. And the vertical sliding rod 310 can play a role in guiding and limiting the pressure pipe plate 311 and the cross plate 309, so that the pressure pipe plate 311 can continuously press and fix the support rod. The lower end surface of the pressure pipe plate 311 is provided with a semi-circular groove, and the diameter of the semi-circular groove is larger than the diameter of the support rod. And a rubber pad with anti-slip effect is installed in the semi-circular groove, thus preventing the tent support rod from being pressed and deformed during continuous extrusion and from shifting under the insertion and pushing of the pipe shrinking device 308.

[0047] It should be noted that the gear ratio between the spur gear 306 and the rack 307 needs to be optimized with the moving speed of the cross plate 309 on the threaded rod 305. So that when the cross plate 309 drives the pressure pipe plate 311 to extrude the support rod, the spur gear 306 can drive the rack 307 to move at the same time. And the pressure pipe plate 311 needs to first press and fix the support rod, and then the rack 307 drives the pipe shrinking device 308 to be inserted into the support rod under the drive of the spur gear 306. It can also be adjusted according to the actual situation. It is recommended that the gear ratio between the spur gear 306 and the rack 307 be selected as 5:1 to achieve the required accuracy.

[0048] Since both ends of the cross plate 309 are respectively slidably and penetratingly connected to the limit vertical rods 301 and threadedly penetrated by the threaded rod 305, when the threaded rod 305 rotates following the output end of the synchronous motor 303 through the second belt transmission device 304, it can drive the cross plate 309 to perform a longitudinal linear movement. Thus, the cross plate 309 drives the pressure pipe plate 311 to move through the cooperation of the compression spring 312 and the vertical sliding rod 310, so that the pressure pipe plate 311 abuts against the tent support rod. And during the continuous movement of the cross plate 309, it squeezes the tent support rod tighter. The rubber pad arranged in the lower semi-circular groove of the pressure pipe plate 311 can be made of silicone rubber with good anti-slip performance and wear resistance. It is recommended that the shore hardness of the silicone rubber be selected between 50A - 60A, thus preventing displacement and other situations during cutting from affecting the cutting, and at the same time being able to relieve the extrusion deformation of the tent support rod. At the same time, the vertical sliding rod 310 and the cross plate 309 are movably penetrated. So when the pressure pipe plate 311 abuts against the pipe, the cross plate 309 can continue to move under the action of the threaded rod 305 and continuously transmit a pressing force to the pressure pipe plate 311 by compressing the compression spring 312. At the same time, it is also for the subsequent rotary cutting mechanism 400 to better cut the tent support rod.

[0049] Reference Figure 2 、 Figure 7 、 Figure 8 On one side of the lower compression tube mechanism 300, a rotary cutting mechanism 400 is provided, and the rotary cutting mechanism 400 is used to cut the tent support rod material to a predetermined size. The rotary cutting mechanism 400 includes a telescopic rod 401 movably penetrating through the middle of the horizontal fixing plate 302. One end of the telescopic rod 401 penetrating through the horizontal fixing plate 302 is on the same longitudinal axis as the output end of the synchronous motor 303, and the surface of one end of the telescopic rod 401 penetrating through the horizontal fixing plate 302 is fixedly connected to the pulley fixedly connected to the output end of the synchronous motor 303 in the second belt transmission device 304. Thus, the output end of the synchronous motor 303 can be fixedly connected and transmitted to the telescopic rod 401 through the pulley in the second belt transmission device 304.

[0050] Reference Figure 2 、 Figure 7 、 Figure 8 One end of the telescopic rod 401 away from the synchronous motor 303 movably penetrates through the cross plate 309 and is mutually limited with the cross plate 309 (as shown in Figure 8 ). Two limiting strips are fixedly arranged on the outer ring surface of the telescopic end of the telescopic rod 401, and limiting grooves with the same size as the limiting strips at the telescopic end are formed on the inner cavity side wall of the retraction end of the telescopic rod 401. Thus, under the mutual insertion and limitation of the limiting strips and the limiting grooves, the whole telescopic rod 401 can rotate synchronously with the synchronous motor 303.

[0051] Reference Figure 8 A third belt transmission device 402 is arranged at the rotational connection of the telescopic rod 401 and the cross plate 309. The third belt transmission device 402 is composed of two synchronous belt pulleys and a synchronous toothed belt. One of the synchronous belt pulleys of the third belt transmission device 402 is fixedly and penetratingly connected to the telescopic end of the telescopic rod 401, and the other synchronous belt pulley in the telescopic rod 401 is rotationally connected and limited to the inner cavity top surface of the outer protective shell 408 fixedly arranged on one side of the cross plate 309. A first bevel gear 403 is fixedly arranged at the lower end of the synchronous belt pulley rotatably arranged in the inner cavity of the outer protective shell 408, and a second bevel gear 404 is meshed on one side of the first bevel gear 403. The middle of the second bevel gear 404 is fixedly penetrated by a rotating shaft 405, and the rotating shaft 405 is rotatably arranged at the lower end of the inner cavity of the outer protective shell 408. One end of the rotating shaft 405 penetrating through the second bevel gear 404 penetrates through the side wall of the outer protective shell 408 and extends outward, and is fixedly connected to the middle of the cutting piece 406 on the surface of the extended end.

[0052] Reference Figure 7 、 Figure 8, a limiting abutting plate 407 is arranged at the lower end of the connection between the rotating shaft 405 and the cutting disc 406, and the limiting abutting plate 407 is fixedly connected with the outer protective shell 408. The length of the limiting abutting plate 407 is greater than the width of the supporting plate 211, and the height of the limiting abutting plate 407 is less than the radius of the cutting disc 406. The distance between the lowest point of the limiting abutting plate 407 and the lowest point of the cutting disc 406 is greater than the diameter of the support rod. Thus, when the cutting disc 406 cuts the support rod and continues to move downward driven by the cross plate 309, the limiting abutting plate 407 can be inserted into the cutting position between the cutting disc 406 and the support rod and inserted through the cutting gap to separate the cut of the support rod from the cutting disc 406. The side of the limiting abutting plate 407 located on one side of the pipe shrinking device 308 is set as an inclined plane, and the side located on one side of the cutting disc 406 is set as a plane. The designed value of the blade thickness of the cutting disc 406 and the gap between the thinnest part of the lower inclined plane of the limiting abutting plate 407 and the cutting disc 406 are set according to the thickness of the cutting disc 406 being 2 mm, the vibration offset being 0.1 mm, and the incision deformation being 0.2 mm. Then, the gap between the thinnest parts of the lower inclined plane of the limiting abutting plate 407 can be designed to be 0.3 - 0.5 mm for actual needs. Thus, the limiting abutting plate 407 can be inserted into the incision position of the support rod. As the outer protective shell 408 continues to move, the limiting abutting plate 407 can push the support rod towards the pipe shrinking device 308, thereby assisting in the pipe shrinking forming between the pipe shrinking device 308 and the support rod. The insertion of the limiting abutting plate 407 can protect the cutting disc 406 and assist in the insertion and pipe shrinking of the support rod and the pipe shrinking device 308, enabling the two to better complete the pipe shrinking.

[0053] It should be noted that by adjusting the meshing of the rack 307 and the spur gear 306, the linear distance between the pipe shrinking device 308 and the cutting disc 406 can be adjusted, thereby being able to adjust the cutting length of the support rod material. At the same time, the gear ratio between the first bevel gear 403 and the second bevel gear 404 is 10:1, and the second bevel gear 404 has 10 teeth, that is, when the first bevel gear 403 rotates one circle, the second bevel gear 404 rotates 10 circles, thereby realizing the high-speed rotation of the cutting disc 406.

[0054] Since the outer protective shell 408 is fixedly connected with the cross plate 309, and one of the belt pulleys of the telescopic rod 401 is fixedly connected with the output end of the synchronous motor 303 through the second belt transmission device 304, when the output end of the synchronous motor 303 rotates, it can drive the telescopic rod 401 to rotate. At the same time, one end of the telescopic rod 401 away from the synchronous motor 303 is fixedly connected with one of the belt pulleys of the third belt transmission device 402, and the other synchronous belt pulley in the third belt transmission device 402 is fixedly connected with the first bevel gear 403. Thus, when the telescopic rod 401 rotates, power is transmitted to the first bevel gear 403 through the third belt transmission device 402, thereby driving the first bevel gear 403 and the telescopic rod 401 to rotate synchronously.

[0055] When the first bevel gear 403 rotates, it will drive the second bevel gear 404 meshed therewith to rotate. Then, the rotation of the second bevel gear 404 drives the rotating shaft 405 to rotate in the inner cavity of the outer protective shell 408, and at the same time drives the cutting piece 406 fixedly connected to the side wall of the outer protective shell 408 through the rotating shaft 405 to rotate. Thus, the cutting piece 406 can cut the support rod during the downward movement of the outer protective shell 408 following the cross plate 309. During the downward movement of the cross plate 309, the telescopic end of the telescopic rod 401 will be pulled. The telescopic end of the telescopic rod 401 is rotationally limited to the cross plate 309, and the telescopic rod 401 is mutually restricted by the limiting strip provided at its telescopic end and the limiting groove opened at its retracting end. Thus, the telescopic rod 401 can rotate following the output end of the synchronous motor 303 while moving following the cross plate 309.

[0056] The implementation principle of the folding tent support rod shrinking and cutting integrated device in the embodiment of the present application is as follows: First, the tent support rod material is transported by the conveying device 101 and abuts against the two rollers 206. Then, through the connection between the first pulley in the first belt transmission device 201 and the conveying device 101, the conveying device 101 drives the first pulley in the first belt transmission device 201 to rotate, and then drives the two second pulleys in the first belt transmission device 201 to rotate, thereby driving the two rollers 206 to rotate, so as to squeeze and limit the support rod pipe material and continue to transport it to the side of the shrinking device 308 until the predetermined length is reached.

[0057] Then, the PLC sends an instruction to the synchronous motor 303 to make the output end of the motor 303 rotate. Then, the synchronous motor 303 drives the threaded rod 305 to rotate. When the threaded rod 305 rotates, it will drive the cross plate 309 to move downward, and through the mutual cooperation of the vertical slide rod 310 and the compression spring 312, the pipe pressing plate 311 is pushed to abut against and limit the support rod and perform preliminary fixation.

[0058] At the same time, when the threaded rod 305 rotates, it will drive the spur gear 306 to drive the rack 307 to move. At the same time, the rack 307 will drive the shrinking device 308 to move towards the support rod side, and at this time, the pipe pressing plate 311 has been preliminarily limited and fixed to the support rod.

[0059] While the cross plate 309 moves, it will pull the telescopic end of the telescopic rod 401 to move synchronously. At the same time, the telescopic rod 401 rotates synchronously under the drive of the output end of the synchronous motor 303. Then, it drives the first bevel gear 403 to rotate through the third belt transmission device 402. While the first bevel gear 403 rotates, it will drive the second bevel gear 404 meshed with it to rotate. Since the tooth ratio between the first bevel gear 403 and the second bevel gear 404 is 10:1, the second bevel gear 404 can drive the rotating shaft 405 and the cutting blade 406 to rotate quickly. After the pressing pipe plate 311 and the support rod are initially limited and fixed, the cutting blade 406 contacts the support rod and cuts under the drive of the cross plate 309. Since the distance between the bottom surface of the limit abutment plate 407 and the lowest part of the cutting blade 406 is greater than the diameter of the support rod, and at the same time, the movement of the cross plate 309 will drive the outer protective shell 408 fixedly connected to it to move synchronously. Then, under the cooperation of the rotary cutting mechanism 400, the cross plate 309 and the synchronous motor 303, the cutting blade 406 can rotate while moving. After the cutting blade 406 completely cuts the support rod, the lowest part of the inclined plane of the limit abutment plate 407 is inserted into the cutting gap between the cutting blade 406 and the support rod, and the cut support rod is pushed and the opening of the support rod is abutted and fixed.

[0060] When the lower inclined plane of the limit abutment plate 407 abuts against the cut opening of the support rod, the pressing pipe plate 311 will further squeeze and fix the support rod. At this time, the pipe shrinking device 308 just plugs into the other opening of the support rod. With the continuous insertion of the limit abutment plate 407 and the continuous movement and extrusion of the cross plate 309, the squeezing and fixing of the support rod by the pressing pipe plate 311 will become tighter and tighter. Then, when the pipe shrinking device 308 shrinks and forms the support rod, it can prevent the support rod from deforming. Since the tooth ratio between the rack 307 and the spur gear 306 is 1:5, under the continuous drive of the rack 307 and the spur gear 306, the support rod is shrunk and formed through the inclined plane inside the pipe shrinking device 308.

[0061] After the pipe shrinking step is completed, the support rod will fall onto the platform at the lower end of the conveying device 101 for collection under the mutual cooperation of the lifting device 210 and the supporting plate 211. Then, loosen the tightening knob on the screw nut head 202, and then turn the handle provided at the upper end of the bidirectional screw rod 203 to make the bidirectional screw rod 203 rotate. Then, drive the two screw nut heads 202 to approach each other, and at the same time drive the two rollers 206 to approach each other along the arc-shaped groove 204, thereby changing the distance between the two rollers 206 and realizing the clamping and conveying of support rods of different sizes.

[0062] While the rollers 206 are approaching each other, the rollers 206 at their lower ends will drive the limit blocks 208, the support platen 209, and the supporting plate 211 to move. The movement of the support platen 209 and the supporting plate 211 will drive the lower compression tube mechanism 300 and the rotary cutting mechanism 400 to move synchronously, so that the entire lower compression tube mechanism 300 and the rotary cutting mechanism 400 can continue to process the support rod without adjustment.

[0063] The above are only optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
