Description

Technical Field

[0001] This application relates to the technical field of hockey production, and in particular to hockey grinding equipment. Background Technology

[0002] Due to its large surface area and slow melting rate, ice balls are widely used in the production of various cold drinks.

[0003] To enhance the unique features and appeal of hockey skating, some hockey skating machines have begun to feature irregular patterns on their surface, giving them a unique texture reminiscent of the lunar surface.

[0004] Currently, common hockey rink making equipment on the market can only produce ordinary hockey rinks with smooth surfaces and uniform shapes, and cannot form the aforementioned irregular moon-shaped patterns on the surface of the hockey rink. Therefore, there is room for improvement. Utility Model Content

[0005] To facilitate the formation of irregular patterns on the surface of the ice hockey rink, this application provides an ice hockey rink polishing device.

[0006] This application provides a hockey polishing device, which adopts the following technical solution: A hockey puck polishing device includes a frame, wherein the frame is provided with a polishing mechanism and a conveying mechanism; The grinding mechanism includes a grinding roller and a first rotary drive component. The grinding roller is rotatably supported on the frame. The first rotary drive component is used to drive the grinding roller to rotate. The grinding roller includes an outer cylinder and an inner cylinder. The inner cylinder is connected to the inner periphery of the outer cylinder. The inner periphery of the inner cylinder is uniformly provided with a plurality of grinding protrusions. The conveying mechanism includes a spiral conveying rod and a second rotary drive component. The spiral conveying rod is rotatably supported on the frame and coaxially passes through the grinding drum. The second rotary drive component is used to drive the spiral conveying rod to rotate.

[0007] By adopting the above technical solution, after the ice ball to be processed is fed into the grinding drum, the first rotary drive and the second rotary drive drive respectively drive the grinding drum and the spiral conveyor rod to rotate. The rotating spiral conveyor rod drives the ice ball to move towards the discharge end of the grinding drum. During this process, the surface of the ice ball is ground by the grinding protrusions on the inner cylinder to form irregular textures on the surface of the ice ball.

[0008] Preferably, the first rotary drive component includes a rotary drive section and a plurality of drive support sections disposed on the frame; The drive support includes two lower supports, both of which are located at the bottom of the grinding drum. Each lower support is rotatably connected to a lower drive wheel, and the rotational axes of the lower drive wheel and the grinding drum are parallel. Both lower drive wheels abut against the grinding drum. The rotary drive unit is connected to the two lower drive wheels and is used to drive the two lower drive wheels to rotate.

[0009] By adopting the above technical solution, the grinding drum is limited by two lower drive wheels, so that the grinding drum can be rotated and supported on the frame; the grinding drum can be rotated by the first rotary drive component driving the two lower drive wheels to rotate.

[0010] Preferably, the drive support further includes an upper support, which is located at the top of the grinding drum. The upper support is rotatably connected to an upper limit wheel, which is arranged parallel to the rotation axis of the grinding drum and abuts against the grinding drum.

[0011] By adopting the above technical solution, the upper limit wheel and two lower drive wheels are used to limit the upper and lower movement of the grinding drum, which helps to limit the radial runout of the grinding drum during rotation and improves the stability of the grinding drum rotation.

[0012] Preferably, the top of the upper support is connected to the frame via an adjusting spring.

[0013] By adopting the above technical solution, the upper support is applied elastic pressure by the adjusting spring so that the upper limit wheel can always be in contact with the grinding drum, reducing the possibility of the upper limit wheel disengaging from the grinding drum due to installation errors or displacement during subsequent operation.

[0014] Preferably, the outer periphery of the grinding roller is provided with an annular limiting groove corresponding to the drive support part, and both the upper limiting wheel and the lower driving wheel are embedded in the annular limiting groove.

[0015] By adopting the above technical solution, and by embedding the upper limit wheel and the lower drive wheel in the annular limit groove, the axial displacement of the grinding drum during rotation is effectively limited, thereby further improving the stability of the grinding drum rotation process.

[0016] Preferably, the grinding protrusion has a first chip removal hole, and the outer cylinder has a second chip removal hole corresponding to the first chip removal hole, and the first chip removal hole and the second chip removal hole are connected.

[0017] By adopting the above technical solution, the ice chips generated during the grinding process can enter the second chip removal hole of the outer cylinder through the first chip removal hole on the grinding protrusion and be discharged from the outer cylinder, reducing the accumulation of ice chips between the annular grinding layer and the ice ball, preventing secondary damage to the surface of the ice ball from the ice chips, and improving the grinding quality of the ice ball.

[0018] Preferably, the frame is provided with a feed hopper and a discharge screen at both ends, and the feed hopper and the discharge screen are respectively connected to the input end and the output end of the grinding roller; the feed hopper and the discharge screen are used to store ice balls.

[0019] By adopting the above technical solution, the feed hopper and the discharge screen are used to store the ice balls to be processed and the processed ice balls respectively, which facilitates the feeding and unloading of the ice balls.

[0020] Preferably, the feed hopper is provided with a pushing assembly, which includes a pushing plate and a pushing drive. The pushing plate is located inside the feed hopper, and the pushing drive is used to drive the pushing plate to move toward or away from the grinding roller.

[0021] By adopting the above technical solution, the pusher drive is used to drive the pusher plate to move the ball ice in the feed hopper into the grinding drum, thereby realizing the automatic feeding of ball ice.

[0022] Preferably, the inner cylinder is fixed to the inner circumference of the outer cylinder by bolts.

[0023] By adopting the above technical solution, a stable connection between the outer cylinder and the inner cylinder can be achieved. When the grinding protrusions wear out or need to be replaced with different styles of grinding protrusions, the inner cylinder can be removed from the outer cylinder, which helps to improve the adaptability of the equipment.

[0024] Preferably, the size of the grinding protrusions in the inner cylinder gradually decreases from the feed end of the grinding roller toward the discharge end of the grinding roller.

[0025] By adopting the above technical solution, during the process of the ice ball moving from the feed end to the discharge end of the drum, it can first be initially polished by larger polishing protrusions to form a basic texture, and then further finely polished by gradually decreasing polishing protrusions, so that the surface texture of the ice ball forms a progressive processing effect, which is conducive to improving the naturalness and aesthetics of the texture.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The rotating spiral conveyor rod drives the ice balls inside the grinding drum to move from the feed end to the discharge end. The grinding protrusions on the rotating inner cylinder grind the outer surface of the ice balls to form irregular patterns on the surface of the ice balls.

[0027] 2. By using the upper limit wheel of the drive support and the two lower drive wheels to limit the upper and lower movement of the grinding drum, the radial runout of the grinding drum during rotation is limited, thus improving the stability of the grinding drum rotation.

[0028] 3. By setting a first chip removal hole and a second chip removal hole on the grinding protrusion and the outer cylinder respectively, the ice chips generated during the subsequent grinding process can be discharged from the grinding roller through the first chip removal hole and the second chip removal hole. This helps to reduce the accumulation of ice chips between the annular grinding layer and the ball ice, avoid secondary damage to the surface of the ball ice by ice chips, and improve the grinding quality of the ball ice.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a hockey polishing device, referring to... Figure 1 and Figure 2The frame 1 is equipped with a grinding mechanism and a conveying mechanism. The grinding mechanism includes a grinding roller 2 and a first rotary drive 20. The grinding roller 2 is rotatably supported on the frame 1, and the first rotary drive 20 is used to drive the grinding roller 2 to rotate. The grinding roller 2 includes an outer cylinder 21 and an inner cylinder 22. The inner cylinder 22 is coaxially connected to the outer cylinder 21, and a plurality of grinding protrusions 23 are evenly protruding on the inner circumference of the inner cylinder 22. The conveying mechanism includes a spiral conveying rod 3 and a second rotary drive 30. The spiral conveying rod 3 is rotatably supported on the frame 1 and coaxially passes through the inner cylinder 22 of the grinding roller 2. The second rotary drive 30 is used to drive the spiral conveying rod 3 to rotate.

[0036] After the ice ball to be processed is fed into the grinding drum 2, the grinding drum 2 and the spiral conveyor 3 are driven to rotate by the first rotary drive 20 and the second rotary drive 30 respectively. While the rotating spiral conveyor 3 pushes the ice ball forward, the grinding protrusions 23 of the inner cylinder 22 are used to grind the surface of the ice ball to form irregular textures on the surface of the ice ball.

[0037] Reference Figure 2 and Figure 3 The inner cylinder 22 is fixed inside the outer cylinder 21 by bolts, achieving a stable connection between the two and facilitating timely replacement of the inner cylinder 22 when the grinding protrusion 23 wears out. The outer cylinder 21 is made of stainless steel; the inner cylinder 22 and the grinding protrusion 23 are made of wear-resistant steel to improve overall durability.

[0038] Reference Figure 2 and Figure 3 The grinding protrusion 23 has a hemispherical structure. Each grinding protrusion 23 has a first chip removal hole 24 at its top, which penetrates the inner cylinder 22. The outer cylinder 21 has a second chip removal hole 25 corresponding to the first chip removal hole 24. The first and second chip removal holes 24 and 25 are opposite to and connected to each other, allowing ice chips generated during subsequent hockey grinding to be discharged promptly through the first and second chip removal holes 24 and 25. This helps prevent ice chips from accumulating inside the inner cylinder 22 and affecting the grinding effect. The second chip removal hole 25 is elongated, facilitating better chip removal.

[0039] Reference Figure 2 and Figure 4The first rotary drive component 20 includes a rotary drive unit 200 and several drive support units mounted on the frame 1. The drive support units are evenly distributed along the length of the frame 1. Each drive support unit includes an upper support 203 and two lower supports 201, arranged in a triangular pattern on the frame 1. The outer cylinder 21 of the grinding roller 2 is located between the upper support 203 and the two lower supports 201. The upper support 203 and lower supports 201 are rotatably connected to an upper limit wheel 204 and a lower drive wheel 202, respectively. The rotational axes of the upper limit wheel 204 and the lower drive wheel 202 are parallel to the rotational axis of the grinding roller 2. The upper limit wheel 204 abuts against the top of the outer cylinder 21 of the grinding roller 2, and the two lower drive wheels 202 abut against the bottom sides of the outer cylinder 21 of the grinding roller 2. This ensures that the grinding roller 2 is stably rotated and supported on the frame 1.

[0040] The lower drive wheels 202 of adjacent drive support units located on the same side of the frame 1 are connected by a drive rod 2021, which helps to improve the rotational synchronization of the lower drive wheels 202 of adjacent drive support units. The rotary drive unit 200 includes two first reduction motors, and the output ends of the two first reduction motors are respectively connected to the two lower drive wheels 202 of the drive support unit near the feed end of the feed roller, so that the two lower drive wheels 202 of each drive support unit are driven to rotate by the two first reduction motors, thereby driving the grinding roller 2 to rotate.

[0041] Two annular limiting plates are coaxially connected to the drive support on the outer periphery of the outer cylinder 21 of the grinding roller 2. A gap is left between the two annular limiting plates to form an annular limiting groove 211. The upper limiting wheel 204 and the lower driving wheel 202 are both embedded in the annular limiting groove 211 to achieve axial limiting of the grinding roller 2, thereby limiting the subsequent rotation of the grinding roller and the axial displacement that occurs during the process.

[0042] The top of the upper support 203 is connected to the top of the frame 1 by two vertically arranged adjusting springs 205. The adjusting springs 205 apply elastic pressure to the upper support 203 so that the upper limit wheel 204 always remains in contact with the grinding roller 2.

[0043] Reference Figure 2 and Figure 4 The rod body and spiral blades of the spiral conveyor 3 are made of stainless steel. The two ends of the spiral conveyor 3 are rotatably connected to the two ends of the frame 1 through connecting seats. The second rotary drive component 30 includes a second geared motor, which is mounted on the frame 1 and the output end of the second geared motor is connected to the end of the spiral conveyor 3 so as to drive the spiral conveyor 3 to rotate.

[0044] Reference Figure 3 and Figure 4There is a gap between the spiral blades of the spiral conveyor rod 3 and the grinding protrusions 23 of the inner cylinder 22, and this gap is smaller than the diameter of the ice ball. This facilitates the smooth rotation of the spiral conveyor rod 3 while ensuring that the rotating spiral conveyor rod 3 can better push the ice ball towards the discharge end of the grinding drum 2.

[0045] Reference Figure 2 and Figure 5 A feed hopper 4 is located near the feed end of the grinding drum 2 on the frame 1. The feed hopper 4 is used to store the ice balls to be processed. The feed hopper 4 is connected to the feed end of the grinding drum 2. A pushing assembly is also provided at the feed hopper 4. The pushing assembly includes a pushing plate 41 and a pushing drive 42. The pushing plate 41 is supported in the pushing hopper and is positioned opposite to the feed end of the grinding drum 2. The pushing drive 42 is used to drive the pushing plate 41 to move towards or away from the grinding drum 2. Specifically, the pushing drive 42 includes a rodless cylinder, which is supported on one side of the feed hopper 4 and the rodless cylinder slide is connected to the pushing plate 41. After the ice balls to be processed are placed into the feed hopper 4, the pushing plate 41 is driven by the rodless cylinder to push the ice balls to be processed into the feed end of the grinding drum 2, thereby realizing automatic feeding of the grinding drum.

[0046] Reference Figure 2 and Figure 5 A discharge screen 5 is installed near the discharge end of the grinding drum 2 on the frame 1. The discharge screen 5 is connected to the discharge end of the grinding drum 2 and is used to receive the ice balls discharged through the discharge end of the grinding drum 2. At the same time, ice chips carried on the surface of the ice balls can be removed by the discharge screen 5.

[0047] The implementation principle of Example 1 is as follows: When grinding ice balls, the first rotary drive 20 and the second rotary drive 30 drive the grinding drum 2 and the spiral conveyor 3 to rotate respectively. After the ice balls to be processed are put into the feed hopper 4, the pusher drive 42 drives the pusher plate 41 to push the ice balls to be processed into the grinding drum 2. While the rotating spiral conveyor 3 pushes the ice balls to the discharge end of the grinding drum 2, the grinding protrusions 23 on the inner cylinder 22 of the grinding drum 2 grind the surface of the ice balls to form irregular textures on the surface of the ice balls.

[0048] Example 2 Reference Figure 2 and Figure 3 The difference between Embodiment 2 and Embodiment 1 is that the size of the grinding protrusions 23 on the inner cylinder 22 gradually decreases from the feed end to the discharge end of the grinding roller 2. As the ice ball passes through the grinding roller 2, it can first undergo preliminary grinding via the larger grinding protrusions 23 to form a basic texture, and then further refine the texture via the smaller grinding protrusions 23. This improves the forming quality of the irregular textures on the surface of the ice ball.

[0049] The implementation principle of Example 2 is the same as that of Example 1, so it will not be described again.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
