Description

Technical Field

[0001] This utility model relates to the field of toilet paper roll packaging technology, specifically an automatic toilet paper roll packaging machine. Background Technology

[0002] The automatic toilet paper roll packaging machine is an automated device designed specifically for individual small packaging of toilet paper rolls. Its core function is to achieve fully automated production from automatic bag length recognition, paper cutting to sealing, significantly reducing manual intervention and waste of packaging materials.

[0003] Chinese patent CN209567130U discloses a roll paper packaging machine, including a packaging machine body. One end of the packaging machine body is equipped with a feeding platform. A laminating conveyor belt is located on the side of the feeding platform near the packaging machine body. A baffle is fixed at the connection between the laminating conveyor belt and the feeding platform, and a film sleeve roller is located below it. A roll paper clamping plate is installed on the feeding platform to limit the displacement and swaying of the roll paper. The clamping distance of the roll paper clamping plate is adjusted by the extension and retraction of the piston rod at the output end of a cylinder. The adjustment method is convenient and quick, and the distance adjustment cost is low. The roll paper clamping plate, in conjunction with a load-bearing spring, can undergo slight deformation to prevent the roll paper from wrinkling or deforming due to clamping force during conveying. The cutting position of the cutting blade can be adjusted by the sliding displacement of the cutter disc on the cutter shaft, accurately cutting off excess laminating film at both ends of the roll paper, facilitating subsequent laminating and heat shrinking operations.

[0004] The surface of the conveyor belt is usually directly exposed to the external environment, making it prone to dust accumulation. As a result, dust may contaminate the surface of the toilet paper roll during the transportation process, leading to a decrease in product quality and ultimately affecting the user's actual experience. Utility Model Content

[0005] The purpose of this invention is to provide an automatic packaging machine for toilet paper rolls, in order to solve the problem mentioned in the background art that dust may contaminate the surface of toilet paper rolls during the transmission process, thereby reducing product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic packaging machine for toilet paper rolls, including a transmission frame, a control box fixedly installed on one side of the transmission frame, a transmission belt drivenly connected to the outer end of the transmission frame, an anti-dust component provided on the inner wall of the transmission frame, a placement rod drivenly connected to one side of the control box, anti-wear components symmetrically opened on the top of the transmission frame, and a limit component provided on the top of the transmission frame. Preferably, the dust-proof assembly includes a rotating shaft, two rotating shafts are symmetrically rotatably connected to the inner wall of the transmission frame, and the outer ends of the two rotating shafts are fitted with torsion springs. A fixing rod is fixedly installed between the two rotating shafts, and a cleaning cotton is detachably connected to the top of the fixing rod.

[0007] Preferably, the wear-resistant component includes through slots, two through slots are symmetrically opened on the top of the transmission frame, and multiple lower rollers are drivenly connected to the inner walls of the two through slots. Multiple limiting wheels are drivenly connected to the inner walls of the through slots, and wear-resistant wheels are symmetrically fixedly installed on the inner walls of the two through slots.

[0008] Preferably, the limiting component includes a bidirectional electric slide rail, which is fixedly installed inside the transmission frame, and the outer end of the bidirectional electric slide rail is symmetrically and slidably connected with a track block.

[0009] Preferably, an L-shaped plate is fixedly installed on one side of each of the two track blocks, and a limit plate is fixedly installed on one side of each of the two L-shaped plates, with a sliding groove slidably connected to the outer end of the L-shaped plate.

[0010] Preferably, the two ends of the torsion spring are fixedly connected to the inner wall of the transmission frame and the fixing rod, respectively, and the cleaning cotton and the surface of the transmission belt are slidably connected.

[0011] Preferably, the limiting wheel is located above the lower roller, and the anti-wear wheel is located at both ends of the through groove.

[0012] Preferably, the sliding grooves are symmetrically arranged on both sides of the transmission frame, and the limiting plate is located above the transmission frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up anti-dust components, dust adhering to the surface of the conveyor belt can be cleaned, preventing dust from contaminating the surface of the toilet paper roll during the transmission process and ensuring the cleanliness of the toilet paper roll before packaging. The cleaning cotton is tightly slidably connected to the surface of the conveyor belt. When the conveyor belt is running, the cleaning cotton can continuously wipe its surface, while the elasticity of the torsion spring ensures that the cleaning cotton always maintains effective contact with the conveyor belt. Even if the cleaning cotton wears down to a certain extent after long-term use, it can be compensated in time by the extension and contraction of the torsion spring to maintain a good cleaning effect, thereby improving the hygiene standards of the entire packaging process. 2. By setting up anti-wear components, the direct contact between the packaging bag and the frame is reduced, while the limit wheels limit the conveyor belt from above to prevent it from deviating during operation. The anti-wear wheels are installed at both ends of the through groove to further buffer the impact force when the packaging bag enters and exits the through groove, and avoid damage to the edges due to excessive friction, thereby ensuring the stable operation of the transmission system and reducing equipment maintenance costs.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 , Figure 2 and Figure 4This utility model provides a technical solution: an automatic toilet paper roll packaging machine, including a transmission frame 1, a control box 2 fixedly installed on one side of the transmission frame 1, a transmission belt 3 drivenly connected to the outer end of the transmission frame 1, an anti-dust-sticking component provided on the inner wall of the transmission frame 1, a placement roller 5 drivenly connected to one side of the control box 2, anti-wear components symmetrically opened on the top of the transmission frame 1, a limit component provided on the top of the transmission frame 1, the anti-dust-sticking component includes a rotating shaft 41, two rotating shafts 41 symmetrically rotatably connected to the inner wall of the transmission frame 1, and torsion springs 42 sleeved on the outer ends of the two rotating shafts 41, and a fixed mounting bracket between the two rotating shafts 41. The top of the fixed rod 43 is detachably connected to a cleaning cotton 44. The two ends of the torsion spring 42 are fixedly connected to the inner wall of the transmission frame 1 and the fixed rod 43, respectively. The cleaning cotton 44 is slidably connected to the surface of the transmission belt 3. In this embodiment, the surface of the transmission belt 3 can be continuously cleaned, effectively avoiding packaging pollution caused by dust and impurities adhering to the surface of the transmission belt 3 during the transmission of toilet paper rolls. Through the elastic force of the torsion spring 42, the cleaning cotton 44 can always be tightly attached to the surface of the transmission belt 3, ensuring the stability of the cleaning effect. At the same time, the detachable design of the cleaning cotton 44 also facilitates later replacement and maintenance, reducing the maintenance cost of the equipment.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5The anti-wear component includes through slots 61, two through slots 61 symmetrically opened on the top of the transmission frame 1, and multiple lower rollers 62 are drivenly connected to the inner walls of the two through slots 61. Multiple limiting wheels 63 are drivenly connected to the inner walls of the through slots 61, and anti-wear wheels 64 are symmetrically fixedly installed on the inner walls of the two through slots 61. The limiting wheels 63 are located above the lower rollers 62, and the anti-wear wheels 64 are located at both ends of the through slots 61 to prevent the packaging bag from wearing against the surface of the transmission frame 1. The anti-wear wheels 64 can replace sliding contact with rolling contact when the packaging bag enters and leaves the through slots 61, further reducing friction loss between the edge of the packaging bag and the equipment, extending the service life of the packaging bag, and improving the stability of packaging quality. The limiting component includes a bidirectional electric slide rail 71, which is fixedly installed... The bidirectional electric slide rail 71 is fixedly installed inside the transmission frame 1. The outer end of the two slide rails 71 is symmetrically and slidably connected to the track blocks 72. L-shaped plates 73 are fixedly installed on one side of each track block 72. Limiting plates 74 are fixedly installed on one side of each L-shaped plate 73. The outer end of the L-shaped plate 73 is slidably connected to the sliding groove 75. The sliding groove 75 is symmetrically opened on both sides of the transmission frame 1. The limiting plate 74 is located above the transmission frame 1. A flexible buffer layer can also be set on the inner side of the limiting plate 74 to avoid squeezing damage to the surface of the toilet paper roll during the limiting process. At the same time, it can further enhance the limiting effect on the transmission position of the toilet paper roll, prevent it from shifting or tipping during high-speed transmission, ensure that the toilet paper roll maintains a stable posture before entering the packaging process, and improve the accuracy and efficiency of subsequent packaging operations.

[0019] Working principle: When the bidirectional electric slide rail 71 is activated, the bidirectional electric slide rail 71 drives the track block 72 to slide along the sliding groove 75, thereby causing the two L-shaped plates 73 and the limiting plate 74 to move closer or further apart. The limiting width is adjusted according to the size of the toilet paper roll. The inner flexible buffer layer contacts the toilet paper roll and stabilizes it. The toilet paper roll is placed on the conveyor belt 3. After the control box 2 is activated, the conveyor belt 3 drives the toilet paper roll to be transported towards the packaging process. During transmission, the cleaning cotton 44 remains in contact with the surface of the conveyor belt 3 under the action of the torsion spring 42. As the conveyor belt 3 moves, it continuously cleans the surface dust and impurities. When the packaging bag is transmitted inside the through groove 61, the edge of the packaging bag rolls into contact with the lower roller 62, the limiting roller 63, and the anti-wear roller 64, ensuring that the packaging bag can accurately enter the subsequent packaging station. The anti-wear roller 64 provides a rolling transition at the key position where the packaging bag enters and exits the through groove 61, so that the packaging bag does not directly contact the edge of the through groove 61. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
