Description

Technical Field

[0001] The utility model relates to the field of waste material rolling, in particular to a waste material rolling device of a bag making machine. Background Art

[0002] A bag making machine is a machine that makes various plastic packaging bags or other material packaging bags. Generally speaking, plastic packaging bags are the main product. During production, the bag making machine will produce a lot of waste plastic ropes, which need to be manually wound around the roller. However, this method is relatively labor-intensive, so the waste winding device of the bag making machine is an indispensable device during the production of the bag making machine.

[0003] At present, most of the existing waste winding devices are reciprocating screw winding devices, air-expanding shaft winding devices and hand-expanding shaft winding devices. When these winding devices are winding up the waste, most of them will install protective plates at the ends to protect the waste wound on the drum, so as to reduce the phenomenon of waste scattering from the ends during the winding process, thereby causing a considerable impact. Under the action of the protective plate, the waste can be effectively protected, so that the waste can only be wound up on the outer wall of the drum, and the waste can be wound up more effectively.

[0004] However, the waste winding device of the above-mentioned bag making machine still has some shortcomings, because the connection method between its protective plate and the end of the roller is a fixed connection with a threaded nut. The protective plate is placed on the end of the roller, and the nut is used to rotate with the thread on the end of the roller to fix the protective plate to the outer wall of the roller. However, this fixing method is relatively cumbersome during disassembly and installation, and consumes a certain amount of working time of the workers. Under long-term use under such conditions, the work efficiency will be reduced. Therefore, it is urgently needed to make improvements on the waste winding device of the bag making machine. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a waste material winding device for a bag making machine to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waste material winding device of a bag making machine, comprising a winding device body, a roller is rotatably installed on the outer wall of the winding device body, and a roller is fixedly installed on the outer wall of the roller, and a protective plate is fixedly installed on the end of the roller, a circular groove corresponding to the end of the roller is formed on the outer wall of the protective plate, and a clamping block is fixedly installed at the center of the circular groove, and a protective ring is fixedly installed on the outer wall of the protective plate, a clamping groove for sliding of the clamping block is formed on the end of the roller, and a baffle is slidably installed on the inner wall of the clamping groove, and a spring is fixedly installed on the outer wall of the baffle, a rotating groove for rotating the clamping block is formed on the inner wall of the clamping groove, and an embedding groove for fixing the clamping block is formed on the inner wall of the clamping groove, and a support component for supporting the protective plate is fixedly installed on the end of the winding device body.

[0007] By adopting the above technical scheme, under the action of the block and the slot, the protective plate can be connected to the roller, so that when the waste is rolled up, the waste is prevented from spreading from one side of the roller, thereby reducing the extra workload of the workers and improving work efficiency. Under the action of the baffle and the spring, after the block is placed in the slot, the baffle squeezes the block under the thrust of the spring, so that the block is fixed inside the slot, so that the protective plate is fixedly connected to the roller, reducing the time required for workers to install the protective plate, allowing workers to better produce finished products, while facilitating workers' installation and improving overall work efficiency.

[0008] The utility model is further configured that the cross-sectional shape of the clamping block is T-shaped, and the shape of the clamping groove corresponds to the shape of the plane at the end of the clamping block.

[0009] By adopting the above technical solution, under the T-shaped setting, when the block is engaged with the slot, the rotation of the block is restricted by the setting of the slot and the block, so that the protective plate cannot rotate when in the slot, thereby restricting the protective plate.

[0010] The utility model is further configured that the other end of the spring is mounted on the inner wall of the end of the clamping slot, and the rotating slot is of cylindrical design, and the diameter of the rotating slot is greater than the diameter of the clamping slot.

[0011] By adopting the above technical solution, when the card block enters the rotating groove, the protective plate is rotated to make the card block rotate in the rotating groove, so that when the card block rotates into the embedded groove, it will be fixed, so that the protective plate is fixed to the end of the roller.

[0012] The utility model is further configured such that the center of the protective ring is consistent with the center of the clamping block, and the inner wall of the protective ring is in contact with the outer wall of the drum.

[0013] By adopting the above technical solution, when the protective plate is connected to the end of the roller, the clamping block is connected to the clamping groove, and the protective ring is fitted to the outer wall of the roller, so that the protective plate is better fixed to the outer wall of the roller.

[0014] The utility model is further configured such that the distance between the baffle and the opening of the block is smaller than the length of the block, the diameter of the baffle is consistent with that of the rotating groove, and the edge of the end of the embedding groove is designed with rounded corners.

[0015] By adopting the above technical solution, the baffle plate only slides in the rotating groove, thereby preventing the baffle plate from sliding out of the end of the clamping groove.

[0016] The utility model is further configured as follows: the supporting assembly consists of a base, a slider, a supporting frame, a roller, a rack and a gear; the base is fixedly mounted on the outer wall of the winding device body, and a slider is slidably mounted on the outer wall of the base, and a supporting frame is fixedly mounted on the outer wall of the slider, a roller for supporting a protective plate is rotatably mounted on the end of the supporting frame, and a fixing rod is slidably mounted on the outer wall of the slider, and a fixing groove for fixing the fixing rod is opened on the outer wall of the base.

[0017] By adopting the above technical solution, under the action of the support assembly, the protective plate is more stable when rotating, and the bearing force at the connection of the roller end is spread out, so that the roller can be better maintained in a horizontal position, so that when rolling up the waste material, the waste material can be rolled up more smoothly, which makes it easier to remove the waste material later.

[0018] The utility model is further configured that two sliders, support frames, rollers and racks are symmetrically installed on the outer wall of the base, and a rack is fixedly installed on the outer wall of the slider, and a gear is rotatably installed on the outer wall of the base, and two racks are symmetrically installed on the outer wall of the gear, and the racks are meshed with the gears.

[0019] By adopting the above technical solution, under the setting of quantity, the protective plate can be better supported, thereby reducing the force borne by the connection at the end of the roller, so that the roller is maintained in a stable horizontal position, so that the main body of the receiving device can be better rolled and fixed when working.

[0020] The utility model is further configured that the end of the fixing rod is designed with rounded corners.

[0021] By adopting the above technical solution and setting the rounded corners, workers can press the end of the fixing rod to make the fixing rod slide downward and fix the slider in a suitable position, which makes it more convenient for workers to use.

[0022] In summary, the utility model mainly has the following beneficial effects:

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1

[0036] A waste material reeling device for a bag making machine, such as Figure 1 - Figure 5As shown, it includes a winding device body 1 and a protective plate 103 , a roller 101 is rotatably mounted on the outer wall of the winding device body 1 , a drum 102 is fixedly mounted on the outer wall of the drum 101 , and a protective plate 103 is fixedly mounted on the end of the drum 102 .

[0037] Specifically, a circular groove 2 corresponding to the end of the roller 101 is formed on the outer wall of the protective plate 103. Through the setting of the circular groove 2, the protective plate 103 is closely connected to the end of the roller 101, so that when the roller 101 is winding, the probability of waste winding around the connection between the protective plate 103 and the end of the roller 101 is reduced, and the winding device body 1 is prevented from getting stuck during operation. A clamping block 3 is fixedly installed at the center of the circular groove 2. Under the action of the clamping block 3, when the protective plate 103 is connected to the roller 101, the clamping block 3 is slidably connected to the end of the roller 101, so that the clamping block 3 obtains a sliding force. A protective ring 4 is fixedly installed on the outer wall of the protective plate 103. When the protective plate 103 is connected to the roller 101, the protective ring 4 slides synchronously. It is installed on the outer wall of the end of the roller 101 to protect the connection between the protective plate 103 and the end of the roller 101, so as to prevent the waste from being entangled around the connection during the winding operation. The end of the roller 101 is provided with a slot 5 for the sliding of the card block 3. Under the action of the slot 5, when the protective plate 103 is connected to the end of the roller 101, the card block 3 can slide more smoothly into the slot 5, so that the connection between the roller 101 and the outer wall of the protective plate 103 is more fitted, and a baffle 6 is slidably installed on the inner wall of the slot 5. When the card block 3 slides into the slot 5, the baffle 6 will be pushed, so that the baffle 6 slides backward, so that the baffle 6 obtains the sliding force, and the outer wall of the baffle 6 is fixedly installed with a spring 7. When the baffle 6 slides backward, the spring 7 will be squeezed synchronously, so as to prevent the baffle 6 from sliding backward. The spring 7 obtains the squeezing force, so that when the spring 7 loses the squeezing force, the baffle 6 will be pushed to reset, and the inner wall of the slot 5 is provided with a rotating groove 8 for the card block 3 to rotate. After the card block 3 enters the slot 5, the baffle 6 is pushed to squeeze the spring 7, so that the end of the card block 3 is fixed in the rotating groove 8, thereby rotating the protective plate 103 ninety degrees, so that the card block 3 is restricted, thereby fixing the protective plate 103 to the end of the roller 101, so that the protective plate 103 can be better fixed at the end of the roller 101, and the inner wall of the slot 5 is provided with an embedding groove 9 for fixing the card block 3. When the card block 3 rotates to ninety degrees in the rotating groove 8, the card block 3 will be fixed in the embedding groove 9, thereby restricting the card block 3, so that when the roller 101 rotates During rotation, the protective plate 103 will not idle, but will rotate with the rotation of the roller 101, so as to better limit the waste material on the outer wall of the roller 101, thereby reducing the probability of waste material scattering during the winding process, and a support assembly 10 for supporting the protective plate 103 is fixedly installed at the end of the winding device body 1. When the winding device body 1 rotates, the protective plate 103 is suspended at one part, so when the waste material on the outer wall of the roller 101 is peeled off, the connection at the end of the roller 101 may be slightly tilted. Under long-term use, the connection at the end of the roller 101 may be deformed. Under the action of the support assembly 10, the protective plate 103 will be supported, thereby reducing the force borne by the connection at the end of the roller 101.

[0038] See also Figure 1 - Figure 5 The cross-sectional shape of the block 3 is T-shaped, and the shape of the slot 5 corresponds to the shape of the plane at the end of the block 3. Under the T-shaped setting, when the block 3 is engaged with the slot 5, the rotation of the block 3 is restricted by the setting of the slot 5 and the block 3, so that the protective plate 103 cannot rotate when it is in the slot 5, thereby restricting the protective plate 103.

[0039] See also Figure 1 - Figure 5 The other end of the spring 7 is installed on the inner wall of the end of the card slot 5, and the rotating slot 8 is designed as a cylinder, and the diameter of the rotating slot 8 is larger than the diameter of the card slot 5. When the card block 3 enters the rotating slot 8, the rotating protective plate 103 makes the card block 3 rotate in the rotating slot 8, so that when the card block 3 rotates into the embedded slot 9, it will be fixed, so that the protective plate 103 is fixed to the end of the roller 101.

[0040] See also Figure 1 - Figure 5 The center of the protective ring 4 is consistent with the center of the block 3. When the protective plate 103 is connected to the end of the roller 101, the block 3 is connected to the slot 5, and the protective ring 4 fits with the outer wall of the roller 101, so that the protective plate 103 is better fixed on the outer wall of the roller 102, and the inner wall of the protective ring 4 fits with the outer wall of the roller 102.

[0041] See also Figure 1 - Figure 5 The distance between the baffle 6 and the opening of the card block 3 is less than the length of the card block 3, so that when the card block 3 enters the card slot 5, when it enters halfway, the end of the card block 3 contacts the baffle 6, so that the card block 3 can better push the baffle 6, and the baffle 6 is consistent with the diameter of the rotating groove 8, so that the baffle 6 can only slide in the rotating groove 8, avoiding the baffle 6 from slipping out of the end of the card slot 5, and the edge of the end of the embedded groove 9 is rounded. Through the rounded design, when the card block 3 rotates, it can slide into the embedded groove 9 more smoothly, so that the installation of the protective plate 103 is consistent. Embodiment 2

Under the action of the support assembly 10, the protective plate 103 is more stable when rotating, and the bearing force at the end connection of the roller 101 is evenly distributed, so that the roller 101 can be better maintained in a horizontal position, so that when rolling up the waste material, the waste material can be rolled up more smoothly, so as to facilitate the removal of the waste material later. The outer wall of the winding device body 1 is fixedly installed with a base 11. Under the action of the base 11, the support assembly 10 can be better fixed on the outer wall of the winding device body 1, so as to better support the protective plate 103, and the outer wall of the base 11 is slidably installed with a slider 12. Pushing the slider 12 can support the protective plates 103 of different sizes, so as to be more convenient for workers to use, and the outer wall of the slider 12 is fixedly installed with a support frame 13. When the slider 12 slides, the support frame 13 will slide synchronously, so that the support frame 13 obtains the sliding force, and the roller 14 for supporting the protective plate 103 is rotatably installed at the end of the support frame 13. Under the action of the roller 14, when the roller 14 contacts the protective plate 103, it will move with the rotation of the protective plate 103, so that when the roller 14 supports the protective plate 103, it will not affect the normal operation of the roller 101, and the outer wall of the slider 12 is slidably installed with a fixing rod 121. Through the setting of the fixing rod 121, when the slider 12 slides to a suitable position, the fixing rod 121 slides downward, thereby fixing the slider 12, so that the slider 12 is fixed in a suitable position, so as to better support the protective plate 103, and the outer wall of the base 11 is provided with a fixing groove 111 for fixing the fixing rod 121. When the fixing rod 121 slides downward, the fixing rod 121 is fixed in the fixing groove 111, thereby fixing the slider 12, so that the slider 12 cannot slide.

With the setting of quantity, the protective plate 103 can be better supported, thereby reducing the force borne by the end connection of the roller 101, so that the roller 101 is maintained in a stable horizontal position, so that the winding device body 1 can be better wound and fixed when working, and the rack 15 is fixedly installed on the outer wall of the slider 12. When the slider 12 slides, it drives the rack 15 to slide synchronously, so that the rack 15 obtains the sliding force, and the outer wall of the base 11 is rotatably installed with a gear 16, and two racks 15 are symmetrically installed on the outer wall of the gear 16, and the rack 15 is meshed with the gear 16.

[0044] See also Figure 6 - Fig. 9The end of the fixing rod 121 is designed with rounded corners. Through the setting of the rounded corners, the worker can press the end of the fixing rod 121, so that the fixing rod 121 slides downward and fixes the slider 12 in a suitable position, which is more convenient for the worker to use.

[0045] The working principle of the utility model is as follows: when in use, the protective plate 103 is fixed to the end of the roller 101, and the card block 3 is slid into the card slot 5, so that the card block 3 pushes the baffle 6, so that the baffle 6 squeezes the spring 7, so that the spring 7 is squeezed, and when the end of the card block 3 slides into the rotating slot 8, the protective plate 103 is rotated 90 degrees in any direction, so that the end of the card block 3 coincides with the embedded slot 9, so that the spring 7 loses its restriction, pushes the baffle 6 to reset, and the baffle 6 pushes the card block 3, so that the card block 3 is fixed in the embedded slot 9, so that the protective plate 103 is The plate 103 is fixed to the end of the roller 101, and when the protective plate 103 is fixed to the roller 101, the protective ring 4 is synchronously sleeved on the outer wall of the drum 102, so as to protect the connection between the protective plate 103 and the roller 101, so that when the winding device body 1 is in use, waste materials will not be entangled in the connection between the protective plate 103 and the roller 101, reducing the probability of damage to the winding device body 1, making it more convenient for workers to use, reducing the time required for installing the protective plate 103, improving work efficiency, and making the winding device body 1 more practical.
