Description

Technical Field

[0001] The invention relates to the technical field of film roll transportation equipment, and in particular to a ground protection film roll track transportation device. Background Art

[0002] After the ground protection film is produced, it needs to be rolled up and collected on a reel. After the ground protection film is rolled up on the reel to form a film roll, it needs to be unloaded from the production equipment and transferred to the warehouse. When transferring the film roll, a film roll transport device is required. Among the film roll transport devices, the track transport device is the most widely used.

[0003] Most of the existing rail transport devices lack a mechanism for decelerating the film roll that is rolled down and loaded thereon, resulting in a large downward impact force on the film roll when it is rolled down and loaded. The large downward impact force will cause mutual collision and damage to the falling film roll and the film roll that has been loaded on the device and will come into contact with the falling film roll. Although some devices are equipped with deceleration mechanisms, the braking deceleration torque and installation height of these mechanisms are not adjustable, resulting in that they are not suitable for braking and decelerating film rolls of different diameters and weights.

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0024] The following is an embodiment of the present invention, please refer to Figures 1 to 9 : The present invention provides a ground protection film roll track transport device, comprising a frame 1, wherein the frame 1 is composed of a horizontally arranged I-shaped base 101 and two symmetrically arranged H-shaped brackets 102; A vertical limiting groove 109 is formed around the horizontal connecting plate of the H-shaped bracket 102 and the two vertical supporting plates; a row of U-shaped deceleration frames 4 arranged at equal intervals are slidably installed on the two vertical supporting plates of the H-shaped bracket 102 along the height direction, and the U-shaped deceleration frames 4 are arranged sideways and can be positioned at a specified position; the head ends of the upper and lower side rods of the U-shaped deceleration frame 4 are slidably installed with vertical deceleration plates 402 (such as Figure 6 As shown in the figure, an inclined intercepting rod 4021 is welded on the vertical deceleration plate 402, which is tilted downward and has a protruding head end and is inserted into the vertical limiting groove 109; the tail parts of the upper and lower side rods of the U-shaped deceleration frame 4 are slidably installed with a vertical force plate 401 that can be positioned, and the parts of the upper and lower side rods of the U-shaped deceleration frame 4 located between the vertical force plate 401 and the vertical deceleration plate 402 are all compressed with springs.

[0025] Preferably, it also includes a reel 3, on which a film roll 301 is wound, and the film roll 301 and the reel 3 are loaded onto the frame 1 from the protective film production equipment, and the two end portions of the reel 3 roll and slide into two vertical limit grooves 109 formed inside the two H-shaped brackets 102 during unloading and loading; a first mounting block 406 is welded to a portion of the upper side rod of the U-shaped deceleration frame 4 close to the H-shaped bracket 102, and the head end portion of the inclined intercepting rod 4021 is inserted into the vertical limit groove 109 When the vertical deceleration plate 402 is in contact with the first mounting block 406, the two end portions of the reel 3 slide downward in the two vertical limit grooves 109 and collide with the protruding portions of the first ends of the two rows of inclined intercepting rods 4021 on the corresponding sides in sequence, and the reel 3 is loaded on the frame 1 in a bottom-up arrangement, and the two adjacent reels 3 are directly in contact with each other; the two end portions of the reel 3 at the bottom side loaded on the frame 1 are respectively in contact with the horizontal connecting plates carried by the two H-shaped brackets 102; When the roll 3 is unloaded and loaded, the four rows of inclined intercepting rods 4021 are pushed by the springs on the upper and lower side rods of the U-shaped deceleration frame 4 to maintain the state of protruding into the two vertical limit grooves 109. In this state, the four rows of inclined intercepting rods 4021 can successively block and intercept the two end parts of the roll 3 rolling down and sliding down along the two vertical limit grooves 109, thereby reducing the falling speed and impact force of the roll 3 and the film roll 301, and preventing the film roll 301 from colliding with the film roll 301 loaded on the frame 1 at its bottom with a large falling impact force, causing mutual collision damage; In the above process, when the two end parts of the reel 3 collide with the four rows of inclined intercepting rods 4021 in turn, through the inclined guiding effect of the four rows of inclined intercepting rods 4021, the reel 3 can impact and drive the four rows of inclined intercepting rods 4021 to slide away from each other from top to bottom in turn, leaving two vertical limit grooves 109 for the intermittent falling loading of its body, and when the four rows of inclined intercepting rods 4021 are driven to slide away from each other in turn, they will compress the springs on the upper and lower side rods of the four rows of U-shaped deceleration frames 4 in turn, and the four rows of springs can rebound in turn to offset part of the falling impact force of the reel 3 when compressed, and gradually reduce the falling speed and impact force of the reel 3; the blocking and deceleration effect of the four rows of inclined intercepting rods 4021 bodies is used together with the rebound offsetting effect of the above four rows of springs, which can implement double and sequential reduction of the falling speed and impact force of the reel 3, effectively reduce the falling impact force of the reel 3, and greatly improve the impact protection effect of the reel 3 during unloading and loading; When the reel 3 is unloaded and loaded, the vertical force plate 401 compresses the two springs on the upper and lower side rods of the U-shaped deceleration frame 4, so as to push the inclined interception rod 4021 through the vertical deceleration plate 402 to keep it in the use state protruding from the vertical limit groove 109, and in this state, the vertical force plate 401 can also transmit its pushing force to the vertical deceleration plate 402 through the two springs, so that the inclined interception rod 4021 can block and decelerate the film roll 301; the vertical force plate 401 is installed in a sliding manner, and sliding it toward or away from the vertical deceleration plate 402 can adjust the tightness and elasticity of the spring, thereby changing the braking deceleration torque indirectly applied to the inclined interception rod 4021; The loading heights of the reels 3 on the two H-shaped brackets 102 are different for film rolls 301 of different diameters. To adapt to the height position change of the reel 3 in this case, the relative distance between the inclined intercepting rod 4021 and the reel 3 needs to be adjusted. The U-shaped deceleration frame 4 is slidably installed, and can slide up and down to adjust the relative distance between the inclined intercepting rod 4021 and the reel 3 on the film rolls 301 of different diameters to cope with the above situation. In this way, the height position and braking torque of the inclined intercepting rod 4021 on the H-shaped bracket 102 can be freely adjusted, which makes the four rows of inclined intercepting rods 4021 suitable for braking and decelerating film rolls 301 of different weights and diameters, so that the deceleration and anti-collision function implemented by the four rows of inclined intercepting rods 4021 is more widely used and more practical.

[0026] Preferably, the two ends of the springs on the upper and lower side rods of the U-shaped deceleration frame 4 are fixedly connected to the vertical force plate 401 and the vertical deceleration plate 402 respectively. When the reel 3 and the film roll 301 are hoisted and unloaded on the frame 1, the four rows of inclined intercepting rods 4021 need to be slid out of the two vertical limit grooves 109 to vacate the two vertical limit grooves 109 for the reel 3 to lift and unload. The vertical force plate 401 is slid significantly in the direction away from the H-shaped bracket 102 to fully rebound and expand the above two springs. The force plate 401 can rely on the springs deployed at the two places to pull and drive the vertical speed reduction plate 402 to slide in the same direction, and pull the inclined intercepting rod 4021 out of the vertical limit groove 109. In this way, the above two springs can be used to adjust the braking torque of the inclined intercepting rod 4021 and to pull out the inclined intercepting rod 4021, which has the effect of using one device for two purposes. This can save the need to configure springs separately for adjusting the braking torque and pulling out the inclined intercepting rod 4021, which helps to simplify the structure of the transportation device to a certain extent.

[0027] Preferably, the two H-shaped brackets 102 are respectively welded to the middle position of the top of the two longitudinal side plates of the I-shaped base 101, and the two vertical support plates of the H-shaped bracket 102 are penetrated along the height direction with a cross-shaped slide groove 1021 (such as Figure 8As shown in the figure, the first ends of the upper and lower side rods of the U-shaped deceleration frame 4 are both in a cross-shaped structure and are both slidably matched with the corresponding cross-shaped chutes 1021 on the H-shaped bracket 102; on both sides of the two vertical plates of the H-shaped bracket 102 facing away from each other, T-shaped chutes 1022 are opened along the height direction. The T-shaped chute 1022 is located at an outer edge position of the vertical plate of the H-shaped bracket 102 away from the film roll 301, and a cross-shaped slider 106 is slidably installed on the T-shaped chute 1022; on the two vertical plates of the H-shaped bracket 102, portions located between the T-shaped chute 1022 and the cross-shaped chute 1021 are all provided with fixing holes 1023 arranged along the length direction of the T-shaped chute 1022.

[0028] Preferably, a second mounting block 407 is welded at the upper side corner position of the U-shaped deceleration frame 4. Both the second mounting block 407 and the first mounting block 406 are located on one side of the U-shaped deceleration frame 4 facing the cross-shaped slider 106. A longitudinal insertion shaft 403 is slidably installed through the second mounting block 407 and the first mounting block 406. And one end of the longitudinal insertion shaft 403 facing the H-shaped bracket 102 is inserted and matched with the fixing hole 1023 at the corresponding height; a limiting ring 4031 is welded and sleeved on the portion of the longitudinal insertion shaft 403 close to the H-shaped bracket 102, and a spring is sleeved on the longitudinal insertion shaft 403. The spring is compressed and placed between the limiting ring 4031 and the second mounting block 407. The longitudinal insertion shaft 403 can insert and position the U-shaped deceleration frame 4 at a specified use height.

[0029] Preferably, the T-shaped long bar portion inside the cross-shaped slider 106 is slidably matched with the T-shaped chute 1022. The T-shaped long bar portion outside protrudes from the T-shaped chute 1022 and is slidably installed with a row of equally spaced sliding sleeves 1062. A connecting rod 404 is rotatably connected between the sliding sleeve 1062 and the corresponding height vertical force-applying plate 401; a row of positioning holes 1061 are opened on the cross-shaped slider 106. A U-shaped positioning frame 1063 is welded on the side of the sliding sleeve 1062 facing away from the H-shaped bracket 102. An L-shaped insertion rod 405 is slidably installed on the U-shaped positioning frame 1063. The horizontal rod section of the L-shaped insertion rod 405 is slidably matched through the vertical side rod of the U-shaped positioning frame 1063 and its first end passes through the sliding sleeve 1062 and is inserted and matched with the positioning hole 1061 at the corresponding height; It should be noted that: the opening spacing of the positioning holes 1061 is equal to the opening spacing of the fixing holes 1023; The connecting rod 404, the vertical force-applying plate 401 and the sliding sleeve 1062 together form a crank-slider mechanism. Through this crank-slider mechanism, sliding the sliding sleeve 1062 up and down can drive the vertical force-applying plate 401 to slide towards or away from the vertical deceleration plate 402, and adjust the braking torque of the inclined intercepting rod 4021; the L-shaped insertion rod 405 is used to insert and fix the sliding sleeve 1062 on the cross-shaped slider 106.

[0030] Preferably, a vertical force transmission rod supporting downward is welded on the side of the limit ring 4031 away from the vertical speed reducer 402, a rod sleeve 4032 is welded on the side of the bottom end of the vertical force transmission rod away from the vertical speed reducer 402, and the vertical rod section of the L-shaped plug rod 405 is penetrated and slidably matched with the rod sleeve 4032 of the corresponding height; When the U-shaped deceleration frame 4 is slidably adjusted, the longitudinal plug shaft 403 and the fixed hole 1023 and the horizontal rod section of the L-shaped plug rod 405 and the positioning hole 1061 need to be pulled out to loosen the sliding sleeve 1062 and the U-shaped deceleration frame 4. The rod sleeve 4032 allows the longitudinal plug shaft 403 to be inserted and matched with the fixed hole 1023, which can also drive the horizontal rod section of the L-shaped plug rod 405 to be inserted and matched with the positioning hole 1061. This allows the sliding sleeve 1062 and the U-shaped deceleration frame 4 to be loosened and tightened synchronously at one time, which helps to indirectly improve the sliding adjustment efficiency of the U-shaped deceleration frame 4. After the frame 4 is adjusted and positioned, when lifting and unloading the reel 3 and the film roll 301, it is necessary to slide the sleeve 1062 downward to withdraw the inclined intercepting rod 4021 from the empty position from the vertical limit groove 109. The sliding cooperation setting of the vertical rod section of the L-shaped plug rod 405 and the rod sleeve 4032 can be used for the independent sliding of the sleeve 1062 from the U-shaped deceleration frame 4 under the above working conditions, thereby ensuring that the synchronous tightening and loosening function of the sleeve 1062 and the U-shaped deceleration frame 4 and the withdrawal operation of the inclined intercepting rod 4021 do not interfere with each other and are compatible with each other, thereby ensuring that the lifting and unloading operations of the reel 3 and the film roll 301 can be implemented normally.

[0031] Preferably, the top ends of the two vertical support plates on the same side of the two H-shaped brackets 102 are welded with upwardly inclined guide plates 103, and when loading the roll 3, the head ends of the two inclined guide plates 103 are aligned with the unloading station of the protective film production equipment.

[0032] Preferably, a horizontally arranged I-shaped driving plate 107 is welded between the bottom ends of the four earth-shaped slide bars 106, and the main part of the I-shaped driving plate 107 is located between the bottom side parts of the two H-shaped brackets 102; a vertical lead screw 108 is rotated at the top center part of the I-shaped base 101, and the vertical lead screw 108 is screwed through the center part of the I-shaped driving plate 107, and a hand wheel is fixedly sleeved on the top of the vertical lead screw 108; The four earth-shaped slide bars 106 are fixedly connected together by an I-shaped driving plate 107. Sliding the I-shaped driving plate 107 up and down can drive the four earth-shaped slide bars 106 and the two rows of sliding sleeves 1062 to slide up and down synchronously, drive and control the four rows of vertical force plates 401 to slide toward each other synchronously, and complete the adjustment of the braking torque of the four rows of inclined intercepting rods 4021 at one time. This saves the cumbersome steps of sliding and driving all the vertical force plates 401 in steps and in sequence when adjusting the braking torque of all the inclined intercepting rods 4021, which helps to improve the adjustment operation efficiency of the braking torque of all the inclined intercepting rods 4021. Similarly, the I-shaped driving plate 107 drives the four earth-shaped slide bars 106 and the two rows of sliding sleeves 1062 slides up and down synchronously, controlling the four rows of vertical force plates 401 to slide toward each other synchronously and greatly to drive the four rows of inclined intercepting rods 4021 to be pulled in and out, and the efficiency of the four rows of inclined intercepting rods 4021 and the two vertical limit grooves 109 to be pulled in and out can also be improved, and the improved efficiency of the pulling in and out operation of the four rows of inclined intercepting rods 4021 helps to indirectly improve the lifting and unloading rate of the reel 3 and the film roll 301; the vertical lead screw 108 can be rotated forward and reversely by the handwheel to push and drive the I-shaped drive plate 107 to slide up and down, and the vertical lead screw 108 can position the I-shaped drive plate 107 in real time, and when the braking torque is adjusted, all the vertical force plates 401 can be kept in the use state after sliding adjustment in real time.

[0033] Preferably, it also includes two symmetrically arranged tracks 2, and long track grooves are provided on opposite sides of the two tracks 2; Rollers are rotatably arranged on the outer sides of the two ends of the two longitudinal side plates of the I-shaped base 101, and the two rollers on each side are rotatably installed in the long track grooves on the corresponding sides; A horizontal mounting plate 104 is welded to the outer bottom of the two H-shaped brackets 102. A tightening bolt 105 is screwed through the horizontal mounting plate 104. The bottom ends of the two tightening bolts 105 are in press contact with the top ends of the two rails 2 respectively. The protective film production equipment is installed at one end of the two tracks 2, and one end of the two tracks 2 close to the protective film production equipment is a material unloading station for the reel 3 and the film roll 301, and the other end is a hoisting and unloading station for the reel 3 and the film roll 301; the two tightening bolts 105 are used to lock and position the frame 1 at the material unloading station or the hoisting and unloading station; It is worth noting that: the two inclined intercepting bars 4021 on the upper side of each row of inclined intercepting bars 4021 are reserved idle settings, that is, the space between these inclined intercepting bars 4021 on the frame 1 cannot be used to load the film roll 301. Since these inclined intercepting bars 4021 can only brake and decelerate the film roll 301 twice at most, the effect of reducing the impact force of the falling film roll 301 is limited. Therefore, forcibly loading the film roll 301 between them will cause impact damage to the film roll 301 loaded therein, and therefore the above setting is required.

[0034] Working principle: The protective film production equipment is installed at one end of the two tracks 2, and the end of the two tracks 2 close to the protective film production equipment is the unloading and loading station for the reel 3 and the film roll 301, and the other end is the hoisting and unloading station for the reel 3 and the film roll 301; the two tightening bolts 105 are used to lock and position the frame 1 at the unloading and loading station or the hoisting and unloading station; When in use, first push the frame 1 to the unloading and loading station to unload the film roll 301 and the reel 3 one by one onto the frame 1. When the frame 1 is fully loaded with the reel 3, push the frame 1 to the hoisting and unloading station. After the film roll 301 and the reel 3 are transferred to the hoisting and unloading station, use the hoisting equipment to lift the film roll 301 and the reel 3 off the frame 1 and transfer them to the designated storage location in the warehouse.
