Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, and in particular to an ice mold sandblasting machine. Background Technology

[0002] An ice mold is a mold used to make ice cubes of a specific shape. Ice molds are made of many different materials, among which stainless steel ice molds are relatively durable.

[0003] After prolonged use, stainless steel ice molds will have residual oxide layers on their surface, which need to be cleaned. This is usually done using an ice mold sandblasting machine.

[0004] The working principle of the ice model sandblasting machine is as follows: first, the stainless steel ice model is fixed, and then the sand pump is started. The sand pump, combined with the sandblasting head, sprays the abrasive pre-stored in the abrasive box at high speed onto the stainless steel ice model, which can form an impact cutting force on the surface of the stainless steel ice model, effectively cleaning the impurities and oxide layer attached to the surface of the stainless steel ice model.

[0005] Currently, existing sandblasting machines for cleaning oxide layers on stainless steel ice molds are generally fixed, and the sandblasting head only performs sandblasting cleaning on a single fixed point, which greatly reduces the sandblasting cleaning effect on oxide layers on the surface of stainless steel ice molds. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing an ice mold sandblasting machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design an ice mold sandblasting machine, including a sandblasting cylinder, a sandblasting platform below the sandblasting cylinder, an abrasive box and a sand pump on the sandblasting platform, a sand pump connected to a sand pump pipe and a main sand conveying pipe, a secondary sand conveying pipe connected to the main sand conveying pipe, a sandblasting head on the secondary sand conveying pipe, an outer support on the sandblasting platform, a vertical cylinder on the outer support, a motor on the vertical cylinder, an inner support on the motor, a clamping cylinder on the inner support, a clamping plate on the clamping cylinder, and an ice mold above the sandblasting cylinder;

[0009] The abrasive box is equipped with a sand supply pipe, the sandblasting cylinder is equipped with a sand discharge pipe, and the sand discharge pipe is equipped with a valve;

[0010] The sandblasting cylinder is equipped with a sand baffle plate, and the inside of the sandblasting cylinder is equipped with a sand guiding surface, which is provided with a smooth layer.

[0011] Furthermore, the inner support has an overall U-shaped structure, and the clamping cylinder and clamping plate are a set, with a total of two sets arranged symmetrically.

[0012] Furthermore, the interior of the sandblasting cylinder is a hollow cavity with an open structure at the top, and the inner diameter of the open inner cavity of the sandblasting cylinder in plan view is not less than the overall size of the clamping cylinder and the inner support in plan view.

[0013] Furthermore, the two ends of the sand extraction pipe are connected to the abrasive box and the sand extraction pump, respectively, and the main sand delivery pipe has a "Z" shaped structure and is connected to the sand extraction pump and the auxiliary sand delivery pipe, respectively.

[0014] Furthermore, there are two auxiliary sand conveying pipes that are symmetrically arranged on the left and right, and two sets of sandblasting heads that are symmetrically arranged on the left and right, with four vertically arranged heads in each set and fixed to the sandblasting cylinder.

[0015] Furthermore, the sandblasting cylinder is a cylindrical structure, and the sand baffle is a ring-shaped structure located at the top of the sandblasting cylinder.

[0016] Furthermore, the upper surface of the sand guiding surface is inclined toward the sand discharge pipe and forms an angle of six degrees with the horizontal plane, and the smooth layer is coated along the upper surface of the sand guiding surface.

[0017] The ice model sandblasting machine proposed in this utility model has the following advantages:

[0018] 1. This utility model, through the setting of a vertical cylinder with an electrically controlled rotating clamping structure, and the setting of a sand pump with a main sand delivery pipe on the sandblasting table, and the setting of a secondary sand delivery pipe structure with multiple sets of sandblasting heads on the main sand delivery pipe, can vertically and stably place the ice mold into the sandblasting cylinder and rotate it at a uniform speed. At the same time, multiple symmetrical sandblasting heads can perform comprehensive sandblasting cleaning on the uniformly rotating ice mold, effectively improving the sandblasting cleaning effect on the surface of stainless steel ice molds with impurities and oxide layers.

[0019] 2. This utility model provides a sand discharge pipe at the central front end of the sandblasting cylinder and an inclined sand guide surface at the bottom of the inner cavity of the sandblasting cylinder. A smooth layer structure is then provided on the surface of the sand guide surface. After sandblasting, the abrasive material can be quickly slid and accumulated at the connection between the sand guide surface and the sand discharge pipe, thereby improving the rapid and convenient discharge of the abrasive material after sandblasting.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-5 An ice mold sandblasting machine includes a sandblasting cylinder 1, a sandblasting platform 2 below the sandblasting cylinder 1, an abrasive box 21 and a sand pump 3 on the sandblasting platform 2, a sand pump 3 connected to a sand pump pipe 31 and a main sand conveying pipe 32, a secondary sand conveying pipe 33 connected to the main sand conveying pipe 32, a sandblasting head 34 on the secondary sand conveying pipe 33, an outer support 5 on the sandblasting platform 2, a vertical cylinder 51 on the outer support 5, a motor 52 on the vertical cylinder 51, an inner support 6 on the motor 52, a clamping cylinder 61 on the inner support 6, a clamping plate 62 on the clamping cylinder 61, and an ice mold 7 above the sandblasting cylinder 1.

[0028] The abrasive box 21 is equipped with a sand replenishment pipe 22, the sandblasting cylinder 1 is equipped with a sand discharge pipe 4, and the sand discharge pipe 4 is equipped with a valve 41;

[0029] The sandblasting cylinder 1 is provided with a sand baffle 11, and the sand blasting cylinder 1 is provided with a sand guiding surface 8. A smooth layer 81 is provided on the sand guiding surface 8. The ice mold 7 is a stainless steel ice mold commonly used for making ice cubes, which is existing technology.

[0030] The abrasive replenishment pipe 22 allows for convenient replenishment of abrasive material into the abrasive box 21.

[0031] The inner support 6 has a U-shaped structure. The clamping cylinder 61 and the clamping plate 62 are a set, and there are two sets symmetrically arranged to achieve stable clamping of the ice mold 7 and ensure the high-pressure sandblasting cleaning effect.

[0032] The outer shell of the clamping cylinder 61, the inner bracket 6, and the outer shell of the motor 52 are all made of stainless steel, which is wear-resistant, impact-resistant, and durable.

[0033] The interior of the sandblasting cylinder 1 is a hollow cavity with an open structure at the top, which ensures that the clamped ice mold 7 can enter vertically for subsequent high-pressure sandblasting cleaning operations.

[0034] The inner diameter of the opening of the sandblasting cylinder 1, viewed from above, is not less than the overall size of the clamping cylinder 61 and the inner support 6 viewed from above. This ensures that the clamping cylinder 61, the inner support 6, and the clamped ice mold 7 are vertically inserted into the sandblasting cylinder 1, while also ensuring the effect of uniform rotation in the later stages.

[0035] The two ends of the sand extraction pipe 31 are connected to the abrasive box 21 and the sand extraction pump 3, respectively. The main sand delivery pipe 32 has a "Z" shaped structure and is connected to the sand extraction pump 3 and the auxiliary sand delivery pipe 33, respectively. The sand extraction pump 3 is a high-pressure pump that can extract the abrasive material preset in the abrasive box 21 at high speed and high pressure, and finally spray it at high pressure through each sandblasting head 34.

[0036] The auxiliary sand conveying pipes 33 are two symmetrically arranged on the left and right, and the sandblasting heads 34 are two sets symmetrically arranged on the left and right. Each set consists of four vertically arranged and inserted and fixed on the sandblasting cylinder 1, so as to realize the rotational sandblasting cleaning of the ice mold 7 rotating at a uniform speed.

[0037] The sandblasting cylinder 1 has an overall cylindrical structure, which ensures the effectiveness of rotating and thoroughly sandblasting the ice mold 7 for cleaning.

[0038] The sand baffle 11 is an overall ring-shaped structure and is set at the top of the sandblasting cylinder 1 to block the abrasive and prevent leakage.

[0039] The upper end of the sand guiding surface 8 is inclined toward the sand discharge pipe 4 and has an angle of six degrees with the horizontal plane. The smooth layer 81 is coated along the upper end of the sand guiding surface 8. The smooth layer 81 is a silicon nitride coating, which has excellent heat resistance and wear resistance, and has a smooth and flat surface. Combined with the inclined sand guiding surface 8, the abrasive material that has been ground can be quickly guided and accumulated at the connection part of the sand discharge pipe 4.

[0040] Working method: First, place the ice mold 7 between the clamping plates 62, then start the clamping cylinder 61. When the clamping plates 62 on both sides stably clamp the ice mold 7, stop the clamping cylinder 61. Next, start the vertical cylinder 51 to move the ice mold 7 downward. After the ice mold 7 sinks into the sandblasting cylinder 1, stop the vertical cylinder 51 and start the motor 52. This will drive the inner support 6 and the ice mold 7 to rotate at a uniform speed. Then, start the sand pump 3 to draw away the abrasive material preset in the abrasive box 21 at high pressure and high speed through the sand pumping pipe 31. Then, through the main sand conveying pipe 32 and the sandblasting head 34, perform high-pressure and high-speed sandblasting on the ice mold 7 that is rotating at a uniform speed. The impact cutting force formed by the high-pressure and high-speed abrasive will effectively and comprehensively clean the residual impurities and oxide layer on the surface of the ice mold 7, effectively improving the sandblasting cleaning effect on the surface of the stainless steel ice mold 7.

[0041] In addition, after sandblasting is completed, the relevant equipment is stopped. At this time, the sandblasted abrasive will slide quickly along the inclined sand guide surface 8 and the smooth layer 81 on the surface and accumulate at the connection of the sand discharge pipe 4. Then, the valve 41 is opened, and the accumulated abrasive can be quickly discharged through the sand discharge pipe 4, which improves the quick and convenient discharge of the blasted abrasive in the later stage.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
