Description

Technical Field

[0001] This utility model relates to the technical field of cold core box core making equipment, specifically a resin box with a weighing function. Background Technology

[0002] The cold box core-making process involves adding resin to core-making sand, mixing the sand in a sand mixer, injecting the sand into the cold box, blowing it into atomized triethylamine, hardening the sand core, and then removing the core. This process is mechanically automated. The amount of binder A and B resin added is a crucial step in the cold box core-making process. In actual production, instances of insufficient resin addition to the sand mixer or addition not meeting the standard amount frequently result in core breakage and waste of raw sand and triethylamine material.

[0003] The main reason is that the resin storage tank is a sealed steel plate welded box, and the human eye cannot quickly and in real time monitor the amount of resin stored in the tank and the output to the sand mixer. Utility Model Content

[0004] The purpose of this invention is to provide a resin box with a weighing function that can monitor the feed rate, instantaneous feed flow rate, discharge rate, and instantaneous discharge flow rate, thereby achieving accurate statistics on resin usage, improving product molding rate, and reducing core-making costs.

[0005] This utility model is implemented as follows:

[0006] A resin tank with a weighing function includes a support frame and a tank body. A weighing sensor is disposed between the tank body and the support frame. The weighing sensor is electrically connected to a timer for measuring the time of weight change. Multiple feeding mechanisms are connected to the top of the tank body. The feeding mechanisms are fixedly connected to the support frame. A stirring mechanism is connected to the tank body.

[0007] Furthermore, the weighing sensor is electrically connected to a display for displaying data.

[0008] Furthermore, the weighing sensor is electrically connected to an alarm for weight indication.

[0009] Furthermore, the stirring mechanism includes a stirring motor fixedly connected to the bracket, and the stirring motor drives a spiral stirring rod.

[0010] Furthermore, the spiral stirring rod has a square wave shape, and the spiral blades of the spiral stirring rod are arranged on the vertical rod.

[0011] Furthermore, the bracket is fixedly connected to multiple triangular hanging plates, and the box is fixedly connected to triangular hanging plates matching the number of triangular hanging plates. The weighing sensor is vertically arranged, with one end of the weighing sensor connected to the triangular hanging plate and the other end of the weighing sensor connected to the triangular hanging plate.

[0012] Furthermore, a lateral limiting rod and a longitudinal limiting rod are horizontally arranged between the box and the support. The lateral limiting rod and the longitudinal limiting rod are vertically arranged in the horizontal direction. The box is fixedly connected to a vertically arranged limiting groove. One end of each of the lateral limiting rod and the longitudinal limiting rod is vertically slidably connected to the box through the limiting groove. The other end of each of the lateral limiting rod and the longitudinal limiting rod is fixedly connected to the support.

[0013] Furthermore, the feeding mechanism includes a spiral auger fixedly connected to the bracket, the input end of the spiral auger is connected to a feed hopper, and the output end of the spiral auger is positioned directly opposite the feed inlet of the housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In practical applications, during feeding, different resins are fed into the chamber through different feeding mechanisms. Weighing sensors measure the weight of each resin entering the chamber, and a timer measures the feeding time. The instantaneous flow rate is obtained from the feeding time and weight. After feeding, a stirring mechanism mixes the resins uniformly. During output, the resin is discharged through the bottom outlet. Weighing sensors measure the weight of the discharged resin, and a timer measures the discharge time. The instantaneous flow rate is obtained from the discharge time and weight. This invention can monitor the feeding amount, instantaneous feeding flow rate, discharge amount, and instantaneous discharge flow rate, enabling accurate statistics on resin usage, improving product molding rate, and reducing core-making costs.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 3 A resin box with a weighing function includes a support 1 and a box body 2. A weighing sensor 3 is provided between the box body 2 and the support 1. The weighing sensor 3 is electrically connected to a timer 4 for measuring the time of weight change. Multiple feeding mechanisms are connected to the top of the box body 2. The feeding mechanisms are fixedly connected to the support 1. A stirring mechanism is connected to the box body 2.

[0023] In practical applications, during feeding, different resins are fed into the housing 2 through different feeding mechanisms. The weight of each resin in the housing 2 is measured by a weighing sensor 3, and the feeding time is measured by a timer 4. The instantaneous flow rate is obtained from the feeding time and the feeding weight. After feeding, the resins are stirred by a stirring mechanism to ensure uniform mixing. During output, the resin is discharged through the bottom outlet. The weight of the resin discharged from the housing 2 is measured by a weighing sensor 3, and the discharge time is measured by a timer 4. The instantaneous flow rate is obtained from the discharge time and the discharge weight. This invention can monitor the feeding amount, instantaneous feeding flow rate, discharge amount, and instantaneous discharge flow rate, enabling accurate statistics on resin usage, improving product molding rate, and reducing core-making costs.

[0024] Please see Figures 1 to 3 The weighing sensor 3 is electrically connected to a display 5 for displaying data.

[0025] The monitor 5 displays the monitored feed rate, instantaneous feed flow rate, discharge rate, and instantaneous discharge flow rate, allowing staff to intuitively obtain the changes in resin feed and discharge within the chamber 2.

[0026] Please see Figures 1 to 3 The weighing sensor 3 is electrically connected to an alarm 6 for weight indication.

[0027] When the weighing sensor 3 detects that the material in the container 2 is lower or higher than the set amount, the alarm 6 will prompt the staff to take appropriate measures.

[0028] Please see Figures 1 to 3 The stirring mechanism includes a stirring motor 7 fixedly connected to the bracket 1, and the stirring motor 7 drives a spiral stirring rod 8.

[0029] The stirring motor 7 drives the spiral stirring rod 8 to rotate, which stirs and mixes the resin in the box 2 in the up and down direction, so that the resin fed in one after another is fully mixed.

[0030] Please see Figures 1 to 3 The spiral stirring rod 8 has a square wave shape, and the spiral blade of the spiral stirring rod 8 is arranged on the vertical rod.

[0031] The square-wave spiral stirring rod 8 provides a larger stirring area and effectively improves stirring efficiency.

[0032] Please see Figures 1 to 3 The bracket 1 is fixedly connected to multiple triangular hanging plates 9, and the housing 2 is fixedly connected to triangular hanging plates 10 matching the number of hanging plates 9. The load cells 3 are vertically arranged, with one end connected to the triangular hanging plate 9 and the other end connected to the triangular hanging plate 10, so that the housing 2 is suspended on the bracket 1 via the triangular hanging plates 9, the load cells 3, and the triangular hanging plates 10. The force on the housing 2 is the sum of the forces on the multiple load cells 3.

[0033] Please see Figures 1 to 3 A horizontal limiting link 11 and a vertical limiting link 12 are horizontally arranged between the housing 2 and the support 1. The horizontal limiting link 11 and the vertical limiting link 12 are vertically arranged in the horizontal direction. The housing 2 is fixedly connected to a vertically arranged limiting groove 13. One end of the horizontal limiting link 11 and the vertical limiting link 12 are vertically slidably connected to the housing 2 through the limiting groove 13. The other end of the horizontal limiting link 11 and the vertical limiting link 12 are fixedly connected to the support 1.

[0034] The horizontally positioned transverse limiting link 11 and longitudinal limiting link 12 form a horizontal limit and are perpendicular to the force direction of the vertically positioned load cell 3. When the box 2 sinks under force, the box 2 slides vertically relative to the transverse limiting link 11 and the longitudinal limiting link 12. That is, the transverse limiting link 11 and the longitudinal limiting link 12 are not subjected to force in the vertical direction, thus not affecting the gravity detection of the load cell 3. At the same time, they play a circumferential limiting role on the box 2, preventing the box 2 from shaking and ensuring the accuracy of the detection by the load cell 3.

[0035] Please see Figures 1 to 3 The feeding mechanism includes a spiral auger 14 fixedly connected to the bracket 1. The input end of the spiral auger 14 is connected to a feed hopper 15, and the output end of the spiral auger 14 is positioned directly opposite the feed inlet of the housing 2.

[0036] The spiral auger 14 is driven to rotate by a rotary motor, which feeds the resin in the feed hopper 15 into the housing 2.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
