Description

Technical Field

[0001] This utility model relates to the field of sports equipment manufacturing technology, specifically an automatic hot melt gluing machine for balls. Background Technology

[0002] Sporting goods manufacturing revolves around the needs of sports, systematically producing specialized equipment that meets athletic performance, safety standards, and user experience through design, material selection, production processes, and quality control. Among these, basketballs, as one of the most globally popular and technologically dynamic team sports equipment, embody the sporting goods industry's ultimate pursuit of functional precision, material innovation, and scenario adaptability in their manufacturing process. In the production of basketballs, the ball blank and the ball skin are usually glued together and fixed, and then processed to produce the finished product. However, the inventors discovered that during the glue application process, due to the ball skin being stored for a long time, the edges of the ball skin will deform to a certain extent. During the glue application process in fully automated equipment, the ball skin will curl up at the edges, affecting the quality of the glue application. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic hot melt gluing machine for balls, which has advantages such as improved gluing quality and solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic hot melt gluing machine for balls, comprising a frame and two frames, the two frames being fixedly installed on the frame, one frame being installed at the middle of the frame, and the other frame being installed at one end of the frame along its length, with drive rollers rotatably connected to the inner walls at both ends of the frame, and a conveyor belt being connected between the two drive rollers, one of the drive rollers being fixedly connected to the output end of an external motor; Inside the frame located in the middle, there are two L-shaped brackets. A glue-applying roller is rotatably connected between the two brackets. A figure-eight shaped elastic frame is fixedly connected to one of the adjacent sides of the two brackets. A pressure roller is rotatably connected to both ends of the two elastic frames that are away from the glue-applying roller. The upper ends of the two supports are equipped with drive components to drive the coating roller to reciprocate. The cleaning assembly for the cleaning conveyor belt is located inside the frame on one side of the rack.

[0005] Furthermore, the driving assembly includes a fixed frame, the inner wall of which has a groove, and a shaped frame is slidably connected to the inside of the fixed frame along the groove. A lead screw is rotatably connected to the inner wall of the fixed frame, and the shaped frame is threadedly connected to the lead screw. A limit rod is fixedly connected to the inner wall of the fixed frame, and the shaped frame is slidably sleeved with the limit rod along its axial direction. An electric push rod is fixedly installed on the inner top wall of the frame adjacent to the fixed frame, and the output end of the electric push rod is fixedly connected to the fixed frame. Two positioning rods are fixedly connected to the upper surface of the fixed frame, and both positioning rods are slidably inserted into the inner top wall of the adjacent fixed frame.

[0006] The above solution enables the lead screw to rotate, driving the irregular frame to move linearly and achieving the horizontal reciprocating motion of the coating roller. The electric push rod can adjust the height of the fixed frame and the coating roller to adapt to the coating requirements of ball skins of different thicknesses. The positioning rod ensures the stability of the fixed frame movement. The overall structure is flexible and precise, improving the applicability of the equipment and the coating accuracy.

[0007] Furthermore, a set of sliding rods is fixedly connected to the upper surface of each of the two supports, and each set of sliding rods is slidably inserted into one end of the irregular frame. A set of springs that are sleeved on the adjacent sliding rods is fixedly connected to the upper surface of each of the two supports, and the other end of each spring is fixedly connected to the irregular frame.

[0008] Through the above scheme, the cooperation between spring one and slide bar can play a buffering role in the glue application process. When the glue application roller is subjected to different pressures, the elasticity of spring one can automatically adjust the pressure between the glue application roller and the ball skin, so that the glue application pressure remains relatively stable, avoiding the glue application quality from being affected by excessive or insufficient pressure, and reducing the wear of equipment parts.

[0009] Furthermore, a scraper is fixedly connected between the two supports, the scraper is in contact with the glue-applying roller, and a collection frame for collecting residual glue is also fixedly connected between the two supports.

[0010] With the above solution, the scraper can remove excess glue from the surface of the glue roller in a timely manner during the glue application process, preventing glue accumulation from affecting the uniformity of glue application. The collection box can collect the scraped-off residual glue, preventing residual glue from dripping and contaminating the equipment and working environment, keeping the equipment clean, and reducing the difficulty of cleaning.

[0011] Furthermore, the cleaning component includes a sliding frame disposed inside the frame, with multiple drainage holes at the bottom end of the sliding frame, a cleaning brush fixedly connected to the bottom end of the sliding frame, a second lead screw rotatably connected to the inner wall of the frame, the upper end of the sliding frame threadedly connected to the second lead screw, multiple sliding cylinders fixedly connected to the inner wall of the frame, a sliding member slidably connected inside each sliding cylinder, a flow cavity formed inside each sliding member, a baffle hinged to the inner wall of each flow cavity, and multiple drainage grooves distributed circumferentially and communicating with the corresponding flow cavities on the outer circumferential surface of each sliding member away from the sliding cylinder.

[0012] With the above solution, the cleaning component can push the sliding component to slide inside the slide cylinder when the sliding frame contacts the sliding component. This increases the pressure inside the slide cylinder and pushes the baffle inside the flow chamber, allowing the cleaning agent inside the slide cylinder to be discharged into the interior of the sliding frame through multiple drainage channels and contact the cleaning brush along the drain hole. Through the reciprocating motion of the cleaning brush and the combined use of the cleaning agent, the surface of the conveyor belt can be cleaned evenly, thereby removing residual adhesive from the surface of the conveyor belt.

[0013] Furthermore, the cleaning assembly also includes a spring two that is fixedly connected between the sliding member and the slide cylinder. A water inlet pipe is fixedly connected to the circumferential surface of the slide cylinder. A water storage chamber is formed at the upper end of the frame. A one-way valve is installed at the other end of the water inlet pipe and is located in the water storage chamber. A water inlet is opened in the central area of ​​the inner top wall of the water storage chamber, and a plug is inserted into the water inlet.

[0014] With the above scheme, the second spring can push the sliding part to reset through its deformation force. When the sliding part is reset, a negative pressure will be formed inside the slide cylinder, and the one-way valve located in the water storage chamber will open, so that the cleaning agent inside the water storage chamber can enter the slide cylinder through the water inlet pipe, so that the cleaning agent can be provided to the cleaning brush when the sliding frame contacts the sliding part next time.

[0015] Furthermore, a limiting rod two is fixedly connected to the inner wall of the frame on one side of the machine frame, and the sliding frame is slidably sleeved with the limiting rod two along the axial direction of the limiting rod two.

[0016] The above scheme provides a limit for the sliding frame by setting the second limiting rod, enabling the sliding frame to slide stably along a straight line.

[0017] Furthermore, two scrapers are fixedly connected to the inner wall of the frame, and the bottom ends of the two scrapers are in contact with the conveyor belt, with the adjacent ends of the two scrapers in contact.

[0018] With the above solution, the two scrapers are combined into a figure-eight contact, which can scrape off the residual glue on the surface of the conveyor belt, prevent the residual glue from entering the subsequent process with the conveyor belt and affecting the quality of the ball skin, reduce the corrosion of the conveyor belt by the residual glue, extend the service life of the conveyor belt, and the figure-eight structure can make the residual glue gather on both sides, which is convenient for cleaning and collection.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This automatic hot-melt gluing machine for balls, through the cooperation of an elastic frame and a pressure roller, enables the pressure roller to uniformly and stably press the ball skin evenly during the glue application process. This keeps the ball skin taut, facilitating glue application and ensuring thorough gluing in every area, thus improving the initial gluing quality. Secondly, the drive assembly allows the glue roller to repeatedly apply glue to the ball skin surface. This reciprocating motion effectively compensates for incomplete coverage that may occur with a single application, further improving the uniformity of the glue on the ball skin surface. Finally, the cleaning assembly, through the cooperation of a cleaning brush and cleaning agent, cleans the surface of the conveyor belt, promptly removing residual glue, impurities, dust, and other contaminants. This prevents these contaminants from adhering to new ball skins during subsequent transport, ensuring the stability of the entire production process and the consistency of product quality.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1 , Figure 2 and Figure 3 An automatic hot melt gluing machine for balls in this embodiment includes a frame 1 and two frames 2. The two frames 2 are fixedly installed on the frame 1. One frame 2 is installed at the middle of the frame 1, and the other frame 2 is installed at one end of the frame 1 along its length. The inner walls at both ends of the frame 1 are rotatably connected to drive rollers 3. A conveyor belt 4 is connected between the two drive rollers 3. One of the drive rollers 3 is fixedly connected to the output end of an external motor.

[0024] Inside the frame 2 located in the middle, there are two L-shaped supports 5. A glue-applying roller 6 is rotatably connected between the two supports 5. An eight-shaped elastic frame 7 is fixedly connected to the adjacent side of each of the two supports 5. A pressure roller 8 is rotatably connected to each end of the two elastic frames 7 away from the glue-applying roller 6. The elastic frame 7 is made of elastic metal and can deform when the pressure roller 8 comes into contact with the material. The elastic deformation force of the elastic frame 7 can make the two pressure rollers 8 press the ball skin tightly, so that the ball skin is in a taut state, which facilitates the glue-applying roller 6 to apply glue evenly to the surface of the ball skin.

[0025] The upper ends of the two brackets 5 are equipped with drive components 9, which are used to drive the glue-applying roller 6 to reciprocate. Through reciprocating motion, the glue-applying roller 6 can apply glue to the ball skin more comprehensively and evenly, avoid glue dead corners, further improve the glue-applying effect, make the glue amount uniform in all parts of the ball skin, and improve the stability of product quality.

[0026] A cleaning component 10 for cleaning the conveyor belt 4 is installed inside the frame 2 located on one side of the frame 1. The cleaning component 10 can clean the impurities and residual glue on the surface of the conveyor belt 4 in a timely manner, prevent the impurities and residual glue from affecting the subsequent conveying and coating of the ball skin, ensure the cleanliness of the conveyor belt 4, maintain the normal operation of the equipment, and extend the service life of the conveyor belt 4.

[0027] The drive assembly 9 includes a fixed frame 901, with a groove formed on the inner wall of the fixed frame 901. A shaped frame 902 is slidably connected to the inside of the fixed frame 901 along the groove. A lead screw 903 is rotatably connected to the inner wall of the fixed frame 901, and the shaped frame 902 is threadedly connected to the lead screw 903. A limit rod 904 is fixedly connected to the inner wall of the fixed frame 901, and the shaped frame 902 is slidably sleeved with the limit rod 904 along its axial direction. An electric push rod 905 is fixedly installed on the inner top wall of the frame 2 adjacent to the fixed frame 901. The output end of the electric push rod 905 is fixedly connected to the fixed frame 901. Two positioning rods 906 are fixedly connected to the upper surface of the fixed frame 901, and both positioning rods 906 are slidably inserted into the inner top wall of the adjacent fixed frame 901. Rotation of the lead screw 903 can drive the shaped frame 902 to perform linear motion, realizing the horizontal reciprocating motion of the coating roller 6. The height of the fixed frame 901 and the glue roller 6 can be adjusted to adapt to the glue application requirements of ball skins of different thicknesses. The positioning rod 906 ensures the stability of the movement of the fixed frame 901. The overall structure is flexible and precise, improving the applicability and glue application accuracy of the equipment. A set of sliding rods 11 are fixedly connected to the upper surface of each of the two brackets 5. Each set of sliding rods 11 is slidably inserted into one end of the irregular frame 902. A set of springs 12 that are sleeved with the adjacent sliding rods 11 are fixedly connected to the upper surface of each of the two brackets 5. The other end of each spring 12 is fixedly connected to the irregular frame 902. The cooperation between the springs 12 and the sliding rods 11 can play a buffering role during the glue application process. When the glue roller 6 is subjected to different pressures, the elasticity of the springs 12 can automatically adjust the pressure between the glue roller 6 and the ball skin, so that the glue application pressure remains relatively stable, avoiding the glue application quality from being affected by excessive or insufficient pressure, and reducing the wear of equipment parts.

[0028] A scraper blade 13 is fixedly connected between the two supports 5. The scraper blade 13 contacts the coating roller 6. A collection frame 14 for collecting residual glue is also fixedly connected between the two supports 5. The scraper blade 13 can scrape off excess glue on the surface of the coating roller 6 in time during the glue application process to prevent glue accumulation from affecting the uniformity of glue application. The collection frame 14 can collect the scraped residual glue to prevent residual glue from dripping and contaminating the equipment and working environment, keeping the equipment clean and reducing the difficulty of cleaning.

[0029] The cleaning component 10 includes a sliding frame 1001 disposed inside the frame 2. Multiple drainage holes 1002 are provided at the bottom end of the sliding frame 1001. A cleaning brush 1003 is fixedly connected to the bottom end of the sliding frame 1001. A lead screw 1004 is rotatably connected to the inner wall of the frame 2. The upper end of the sliding frame 1001 is threadedly connected to the lead screw 1004. Multiple sliding cylinders 1005 are fixedly connected to the inner wall of the frame 2. A sliding member 1006 is slidably connected inside each sliding cylinder 1005. A flow cavity 1007 is formed inside each sliding member 1006. A baffle 1008 is hinged to the inner wall of each flow cavity 1007. The end of each sliding member 1006 away from the sliding cylinder 1005... Multiple drainage grooves 1009, arranged circumferentially and connected to corresponding flow cavities 1007, are provided on the outer circumferential surface. When the sliding frame 1001 contacts the sliding member 1006, the cleaning component 10 pushes the sliding member 1006 to slide within the sliding cylinder 1005, increasing the pressure within the sliding cylinder 1005 and pushing the baffle 1008 inside the flow cavity 1007. This allows the cleaning agent inside the sliding cylinder 1005 to be discharged through the flow cavity 1007 from the multiple drainage grooves 1009 into the interior of the sliding frame 1001, and then contacts the cleaning brush 1003 along the drain hole 1002. Through the reciprocating motion of the cleaning brush 1003 and the combined use of the cleaning agent, the surface of the conveyor belt 4 can be cleaned. The cleaning assembly 10 performs uniform cleaning to remove residual adhesive from the surface of the conveyor belt 4. The cleaning assembly 10 also includes a spring 1010 fixedly connected between a sliding member 1006 and a slide cylinder 1005. A water inlet pipe 1011 is fixedly connected to the circumferential surface of the slide cylinder 1005. A water storage chamber 1012 is formed at the upper end of the frame 2. A one-way valve 1013 is installed at the other end of the water inlet pipe 1011 and located within the water storage chamber 1012. A water inlet is provided in the central area of ​​the inner top wall of the water storage chamber 1012, and a plug 1014 is inserted into the inlet. A through hole communicating with the outside is formed in the inner top wall of the water storage chamber 1012. The spring 1010 can push the sliding member 1006 through its deformation force. 06 Reset: When the sliding member 1006 resets, a negative pressure will be formed inside the sliding cylinder 1005. The one-way valve 1013 located in the water storage chamber 1012 will open, allowing the cleaning agent inside the water storage chamber 1012 to enter the sliding cylinder 1005 through the water inlet pipe 1011. This facilitates the provision of cleaning agent to the cleaning brush 1003 when the sliding frame 1001 contacts the sliding member 1006 next time. The inner wall of the frame 2 located on one side of the frame 1 is fixedly connected to the limit rod 2 15. The sliding frame 1001 slides along the axis of the limit rod 2 15. The limit rod 2 15 can provide a limit to the sliding frame 1001, so that the sliding frame 1001 can slide stably along a straight line.

[0030] Two scrapers 16 are fixedly connected to the inner wall of the frame 1. The bottom ends of the two scrapers 16 are in contact with the conveyor belt 4, and the adjacent ends of the two scrapers 16 are in contact. The two scrapers 16 are combined to form a figure-eight contact, which can scrape off the residual glue on the surface of the conveyor belt 4, prevent the residual glue from entering the subsequent process with the conveyor belt 4 and affecting the quality of the ball skin, reduce the corrosion of the conveyor belt 4 by the residual glue, extend the service life of the conveyor belt 4, and the figure-eight structure can make the residual glue gather on both sides, which is convenient for cleaning and collection.

[0031] It should be noted that one end of lead screw 1 (903) and lead screw 2 (1004) are respectively fixedly connected to the output end of an external motor. The working principle of the above embodiment is as follows: First, when applying glue to the surface of the ball skin, an external motor drives one of the transmission rollers 3 to rotate and drives the conveyor belt 4 to transport the ball skin. When the ball skin is below the glue-applying roller 6, the electric push rod 905 can push the fixed frame 901 down, so that the glue-applying roller 6 can contact the ball skin. At this time, the two pressure rollers 8 can contact the ball skin and press the ball skin with the deformation force of the elastic frame 7, so that the ball skin can be in a taut state, so that the glue-applying roller 6 can apply glue to the surface of the ball skin more evenly. When the glue-applying roller 6 contacts the ball skin, the deformation force of the spring 12 It can provide a buffer force for the coating roller 6, so as to avoid the excessive impact force when the coating roller 6 contacts the ball skin, which may cause indentation on the surface of the ball skin or damage to the coating roller 6 itself. Then, the external motor drives the lead screw 903 to rotate. During the rotation, the lead screw 903 can drive the special frame 902 to reciprocate, thereby driving the coating roller 6 to repeatedly apply glue to the surface of the ball skin, thereby improving the uniformity of the glue application. During the glue application process, the scraper can scrape off the excess glue on the surface of the coating roller 6. The residual glue will enter the collection frame 14 under the action of gravity for easy recycling.

[0032] During the glue application process, an external motor drives the lead screw 1004 to rotate, causing the sliding frame 1001 to reciprocate within the adjacent frame 2. This reciprocates the movement of the cleaning brush 1003, cleaning the surface of the conveyor belt 4. When the sliding frame 1001 contacts the sliding member 1006, the sliding member 1006 slides within the sliding cylinder 1005, compressing the cleaning agent inside and compressing the spring 1010. As the pressure inside the sliding cylinder 1005 increases, the baffle 1008 swings into the flow chamber 1007, connecting the flow chamber 1007 with the sliding cylinder 1005. This allows the cleaning agent inside the sliding cylinder 1005 to be discharged into the sliding frame 1001 through the flow chamber 1007 and the drain trough 1009, and then contacts the cleaning brush 1003 along the drain hole 1002. 3. When used in conjunction with cleaning agent, the conveyor belt 4 can be cleaned more thoroughly. When the sliding frame 1001 separates from the sliding member 1006, the deformation force of the second spring 1010 will push the sliding member 1006 to reset. At this time, the baffle 1008 can close the flow chamber 1007. When the sliding member 1006 slides in the slide cylinder 1005 under the push of the second spring 1010, a negative pressure will be generated inside the slide cylinder 1005. At this time, the one-way valve 1013 located inside the water storage chamber 1012 will open, and the cleaning agent in the water storage chamber 1012 will enter the slide cylinder 1005 through the water inlet pipe 1011, which is convenient for spraying cleaning agent on the cleaning brush 1003 next time. Finally, through the conveyor belt 4, the surface of the conveyor belt 4 will come into contact with the scraper 16. The two scrapers 16 can scrape off the residual adhesive on the surface of the conveyor belt 4 and through the movement of the conveyor belt 4, the residual adhesive will be discharged to both sides of the frame 1.
