[0043] Example

[0044] Please refer to Figure 1 The present embodiment provides an automatic glue making system 100, including an additive delivery mechanism 1, a plasticizer delivery mechanism 2, a stirring kettle 3, a feeding kettle 4, a storage device 5 and a control device.

[0045] In this embodiment, the additive delivery mechanism 1 includes an additive raw material barrel 11, an additive pumping assembly 12 and an additive weighing tank 13 connected in sequence through an additive delivery pipeline 14; the plasticizer delivery mechanism 2 includes a plasticizer raw material tank 21, a plasticizer pumping assembly 22 and a plasticizer weighing tank 23 connected in sequence through a plasticizer delivery pipeline 24; the stirring kettle 3 is respectively connected to the discharge end of the additive weighing tank 13 and the discharge end of the plasticizer weighing tank 23, and the stirring kettle 3 is provided with a powder input port for manual input of resin powder; the unloading kettle 4 is connected to the discharge end of the stirring kettle 3 The material end is connected, and the colloid that is stirred and mixed evenly is sent into the feeding kettle 4; the storage device 5 is connected to the material discharge end of the feeding kettle 4, and the material discharge flow rate and the material discharge amount of the feeding kettle 4 are controlled according to the process requirements; the control device is a PLC controller, which is electrically connected to the auxiliary agent conveying mechanism 1, the plasticizer conveying mechanism 2, the stirring kettle 3 and the feeding kettle 4, respectively, and is used to control the auxiliary agent conveying mechanism 1 to convey the auxiliary agent raw material, control the plasticizer conveying mechanism 2 to convey the plasticizer raw material, control the stirring kettle 3 to stir the mixed material (auxiliary agent, plasticizer and resin powder), and control the feeding kettle 4 to discharge the material. The automatic glue making system 100 realizes the automatic conveying and weighing of auxiliary agent raw materials and plasticizer raw materials, and the automatic stirring of mixed materials, with high precision, high controllability, low labor intensity, and saved production costs.

[0046] The specific structures of the various components of the automatic glue making system 100 and the positional relationships therebetween are described in detail below.

[0047] The additive delivery mechanism 1 includes an additive raw material barrel 11, an additive pumping assembly 12 and an additive weighing tank 13, which are connected by additive delivery pipes 14. The additive raw material barrel 11 contains the required additive raw materials and is used to contain the additives; the additive pumping assembly 12 is used to deliver the additives from the additive raw material barrel 11 into the additive weighing tank 13; the additive weighing tank 13 is used to weigh and store the additives delivered into the additive weighing tank 13 by the additive pumping assembly 12. The additive delivery mechanism 1 is connected to the control device, and the user controls the working state of the additive delivery mechanism 1 by operating the control device to realize the delivery and weighing of the additive raw materials.

[0048] It should be pointed out that since there are multiple types of auxiliary raw materials, each auxiliary raw material uses an auxiliary raw material barrel 11, each auxiliary raw material has a set of auxiliary pumping components 12, and multiple auxiliary pumping components 12 enter the same auxiliary weighing tank 13.

[0049] In this embodiment, the additive pumping assembly 12 is a screw pump with a motor (refer to the screw pump of the prior art), and the additive raw material barrel 11, the screw pump and the additive weighing tank 13 are connected in sequence through the additive delivery pipeline 14. The screw pump is electrically connected to the control device, and the control device can control the working state of the screw pump. After receiving the start signal of the control device, the screw pump works to pump the additive raw material and send it into the additive weighing tank 13; after receiving the stop signal of the control device, the screw pump stops working. Figure 2 As shown, a first start-up valve 61 is connected to the additive delivery pipeline between the screw pump and the additive raw material barrel 11. The first start-up valve 61 is electrically connected to the control device. The control device can control the working state of the first start-up valve 61. When additive delivery is required, the first start-up valve 61 opens after receiving the opening signal of the control device, and the screw pump can extract the additive raw material in the additive raw material barrel 11 and deliver it into the additive weighing tank 13 through the additive delivery pipeline 14; after receiving the closing signal of the control device, the first start-up valve 61 closes, and the screw pump cannot extract the additive raw material from the additive raw material barrel 11.

[0050] It should be pointed out that the additive pumping assembly 12 can also be other delivery pumps, and reference can be made to the liquid pumping equipment in the prior art, and the user can select one according to actual conditions.

[0051] In order to ensure the quality of the auxiliary raw materials, a first filter 121 is connected between the auxiliary raw material barrel 11 and the auxiliary delivery pipeline 14 of the screw pump. The first filter 121 is located between the first start valve 61 and the screw pump. After passing through the first start valve 61, the auxiliary raw materials flow through the first filter 121 for filtration. The filtered auxiliary raw materials enter the screw pump and are sent to the auxiliary weighing tank 13.

[0052] Furthermore, a first discharge valve 71 is connected to the additive delivery pipeline 14 between the screw pump and the additive weighing tank 13, and the first discharge valve 71 is located at the discharge end of the screw pump. When the motor of the screw pump is damaged and needs to be replaced, or when the pipeline needs to be replaced, the first discharge valve 71 is manually closed to enable replacement and maintenance, which is convenient for shutdown operation.

[0053] like Figure 3As shown, the feed end of the additive weighing tank 13 is connected with a second start-up valve 62 and a second discharge valve 72, and the discharge end of the additive weighing tank 13 is connected with a third start-up valve 63 and a third discharge valve 73, and the second start-up valve 62 and the third start-up valve 63 are electrically connected to the control device, respectively. Under the control of the control device, the opening of the second start-up valve 62 can allow the additive raw material to enter the additive weighing tank 13, and the opening of the third start-up valve 63 can allow the additive mixture in the additive weighing tank 13 to enter the stirring tank 3. Through the control of the control device, the automatic weighing and transportation of the additive raw material is realized, the weighing accuracy is improved, and labor is saved. The second discharge valve 72 and the third discharge valve 73 are used for the replacement and maintenance of the pipeline, which is convenient for shutdown and maintenance. The additive weighing tank 13 is electrically connected to the control device, and the specified weight of the additive raw material can be weighed through the control device.

[0054] Since the amount of auxiliary raw materials used is less than the amount of plasticizer used, during the weighing process, if the amount of auxiliary raw materials is insufficient and it is necessary to add auxiliary raw materials, it will waste time to transport the auxiliary raw materials from the auxiliary raw material barrel 11. In this embodiment, a storage tank 15 is connected to the auxiliary raw material delivery pipeline 14 between the screw pump and the auxiliary weighing tank 13, the feed end of the storage tank 15 is connected to the screw pump, and the discharge end of the storage tank 15 is connected to the auxiliary weighing tank 13. During the feeding operation, the auxiliary raw materials are first transported to the storage tank 15, and part of the auxiliary raw materials are stored in the storage tank 15. At the same time, a quantitative amount of auxiliary raw materials is transported from the storage tank 15 to the auxiliary weighing tank 13 according to the formula requirements. When the auxiliary weighing tank 13 needs to be supplemented with auxiliary raw materials, the control device controls the second start valve 62 to open, so that the auxiliary raw materials in the storage tank 15 can enter the auxiliary weighing tank 13.

[0055] It should be pointed out that since a variety of auxiliary raw materials are required, in the present embodiment, each auxiliary raw material corresponds to a storage tank 15, and the storage tanks 15 for each auxiliary raw material are respectively connected to the auxiliary weighing tank 13, which is equivalent to storing the corresponding auxiliary raw material in the storage tank 15 for each auxiliary raw material, and the multiple auxiliary raw materials enter the same auxiliary weighing tank 13 through their respective storage tanks 15 and are mixed in the auxiliary weighing tank 13.

[0056] Furthermore, the storage tank 15 is provided with a first liquid level gauge 151 and a second liquid level gauge 152. The first liquid level gauge 151 is closer to the feeding end of the storage tank 15 relative to the second liquid level gauge 152 (the first liquid level gauge 151 is at a high liquid level, and the second liquid level gauge 152 is at a low liquid level). The first liquid level gauge 151 and the second liquid level gauge 152 are electrically connected to the control device, respectively. When the first liquid level gauge 151 detects that the liquid level in the storage tank 15 reaches the position of the first liquid level gauge 151, it generates a first liquid level signal and sends it to the control device. The control device controls the first start valve 61 to close and stop feeding the storage tank 15. When the second liquid level gauge 152 detects that the liquid level in the storage tank 15 reaches the position of the second liquid level gauge 152, it generates a second liquid level signal and sends it to the control device. The control device controls the first start valve 61 to open and feed the storage tank 15.

[0057] It should be pointed out that the auxiliary agent raw material is in liquid state, and the connection of the auxiliary agent delivery pipeline 14 needs to be sealed.

[0058] The plasticizer delivery mechanism 2 includes a plasticizer raw material tank 21, a plasticizer pumping assembly 22 and a plasticizer weighing tank 23, and the plasticizer raw material tank 21, the plasticizer pumping assembly 22 and the plasticizer weighing tank 23 are respectively connected by a plasticizer delivery pipeline 24. The plasticizer raw material tank 21 contains the required plasticizer raw material for containing the plasticizer. The plasticizer pumping assembly 22 is used to deliver the plasticizer from the plasticizer raw material tank 21 into the plasticizer weighing tank 23. The plasticizer weighing tank 23 is used to weigh and store the plasticizer delivered into the plasticizer weighing tank 23 by the plasticizer pumping assembly 22. The plasticizer delivery mechanism 2 is connected to the control device, and the user controls the working state of the plasticizer delivery mechanism 2 by operating the control device to realize the delivery and weighing of the plasticizer raw material. The plasticizer pumping assembly 22 can also be other delivery pumps, which can refer to the liquid pumping equipment in the prior art, and the user can select according to the actual situation.

[0059] It should be pointed out that since there are multiple types of plasticizer raw materials, each plasticizer raw material corresponds to a plasticizer raw material tank 21 , each plasticizer raw material has a set of plasticizer pumping components 22 , and multiple plasticizer pumping components 22 enter the same plasticizer weighing tank 23 .

[0060] In this embodiment, the plasticizer pumping assembly 22 is a centrifugal pump with a motor (refer to the centrifugal pump of the prior art). The centrifugal pump is electrically connected to the control device, and the control device can control the working state of the centrifugal pump. After receiving the start signal of the control device, the centrifugal pump works to pump the plasticizer raw material into the plasticizer weighing tank 23; when the centrifugal pump receives the stop signal of the control device, the centrifugal pump stops working. Figure 4As shown, the feeding end of the plasticizer weighing tank 23 is connected to the fourth discharge valve 74 and the fourth start-up valve 64, and the discharging end of the plasticizer weighing tank 23 is connected to the fifth discharge valve 75 and the fifth start-up valve 65, and the fourth start-up valve 64 and the fifth start-up valve 65 are electrically connected to the control device respectively. The control device controls the fourth start-up valve 64 to open, and the plasticizer raw material can be fed into the plasticizer weighing tank 23 and weighed and stored. The control device controls the fifth start-up valve 65 to open, and the plasticizer mixture in the plasticizer weighing tank 23 can enter the stirring tank 3. Figure 5 As shown, a manual valve 66 and a sixth discharge valve 76 are connected to the plasticizer delivery pipeline 24 between the centrifugal pump and the plasticizer raw material tank 21, and the manual valve 66 is in a normally open state; the discharge end of the centrifugal pump is connected to the seventh discharge valve 77. The fourth discharge valve 74, the fifth discharge valve 75, the sixth discharge valve 76 and the seventh discharge valve 77 are provided to facilitate the replacement and maintenance of the pipeline or the centrifugal pump, and to facilitate shutdown and maintenance. The plasticizer weighing tank 23 is electrically connected to the control device, and the control device can control the plasticizer weighing tank 23 to weigh the plasticizer mixture of a specified weight.

[0061] In order to ensure the quality of the plasticizer raw material, a second filter 221 is connected between the plasticizer raw material tank 21 and the plasticizer delivery pipeline 24 of the centrifugal pump. After being filtered by the second filter 221, the plasticizer raw material is delivered to the plasticizer weighing tank 23 by the centrifugal pump.

[0062] Furthermore, in order to recycle the plasticizer raw material, a plasticizer reflux pipe 25 is connected between the plasticizer weighing tank 23 and the plasticizer raw material tank 21. When the plasticizer raw material delivery process exceeds the demand, after closing the fourth start-up valve 64, the plasticizer raw material cannot enter the plasticizer weighing tank 23, and the plasticizer raw material flows back to the plasticizer raw material tank 21 through the plasticizer reflux pipe 25, so as to realize the recycling of the plasticizer. In order to ensure the stable delivery of the plasticizer raw material, a flow stabilizing valve is connected to the plasticizer reflux pipe 25 to stabilize the flow rate of the plasticizer.

[0063] It should be pointed out that the plasticizer raw material is in liquid state, and the connection of the plasticizer delivery pipeline 24 needs to be sealed.

[0064] In this embodiment, the stirring tank 3 is provided with a powder input port, and the user can input a preset weight of resin powder into the stirring tank 3 through the diversion input port. The stirring tank 3 is used to mix the auxiliary agent mixture (the auxiliary agent flowing out of the auxiliary agent weighing tank 13 is an auxiliary agent mixture obtained by mixing multiple auxiliary agent raw materials, which is different from a single auxiliary agent raw material), the plasticizer mixture (the plasticizer flowing out of the plasticizer weighing tank 23 is a plasticizer mixture obtained by mixing multiple plasticizer raw materials, which is different from a single plasticizer raw material) and the resin powder into a colloid. Figure 6As shown, the discharging end of the stirring kettle 3 is connected with a sixth start-up valve 67, which is electrically connected to the control device. The sixth start-up valve 67 is started under the control of the control device, and the colloid in the stirring kettle 3 can flow into the unloading kettle 4. Since the resin powder will generate dust during the feeding process, a dust removal device is provided at the powder feeding port of the stirring kettle 3 to facilitate the collection of dust.

[0065] As an optional mode of this embodiment, the stirring speed of the stirring tank 3 is 1000rpm, and the stirring time can be set according to the process requirements. The high speed can facilitate the uniform mixing of the auxiliary agent mixture, the plasticizer mixture and the resin powder, and is convenient for improving the quality of the colloid. In other embodiments of the present invention, the stirring speed of the stirring tank 3 can also be other values, and the user can select according to the actual situation.

[0066] The feeding kettle 4 is located below the stirring kettle 3. When the colloid is made, the sixth start valve 67 is opened, and the colloid enters the feeding kettle 4. The storage device 5 is located below the feeding kettle 4. The user can open the feeding kettle 4 according to the actual demand to realize the packaging of the colloid.

[0067] In order to facilitate the storage and transportation of the colloid, the storage device 5 is a storage barrel with running wheels. When the storage barrel is filled with the required colloid, the storage barrel can be transported to a designated location according to process requirements, thereby improving the moving efficiency.

[0068] In this embodiment, the control device is a PLC controller (the PLC controller is preset with the programs required for each process). The user controls the designated electrical components (centrifugal pumps, screw pumps, weighing tanks, various starting valves and other components) through the PLC controller according to different usage requirements to complete the designated actions. The setting of the PLC controller improves the degree of automation in the rubber production, realizes the weighing and automatic transportation of auxiliary raw materials and plasticizer raw materials, and reduces labor. It should be pointed out that the PLC controller is a prior art and is set with designated programs, which will not be introduced in detail in this embodiment. Figure 7 As shown, it is the control principle diagram of the control device of this embodiment.

[0069] The embodiment of the present invention further provides a method for making glue, using the automatic glue making system 100 described above, and the specific steps are as follows:

[0070] Step S1: start the control device and execute the following steps under the control of the control device;

[0072] Step S2: feeding the additive raw material in the additive raw material barrel 11 into the additive weighing tank 13 through the additive pumping component 12 to form an additive mixture, weighing the additive mixture, and feeding the additive mixture of a preset weight A into the stirring tank 3;

[0073] In this step, the additive pumping component 12 uses a screw pump to first transport various additive raw materials to their respective storage tanks 15 through the screw pump, and store them in the corresponding storage tanks 15; according to the needs, each additive raw material of a specified weight is sent to the same additive weighing tank 13 to form an additive mixture, the weight of the additive mixture is weighed, and the additive mixture of a preset weight A is sent to the stirring tank 3. According to the requirements of the process, various additive raw materials enter the additive weighing tank 13 respectively and are weighed, and various additive raw materials are mixed in the additive weighing tank 13 to form an additive mixture, and the additive mixture of a preset weight A is sent to the stirring tank 3;

[0075] In this step, the plasticizer pumping assembly 22 uses a centrifugal pump, and various plasticizer raw materials are transported to the plasticizer weighing tank 23 through the corresponding centrifugal pumps, and the weight is weighed. Various plasticizer raw materials are mixed in the plasticizer weighing tank 23 to form a plasticizer mixture, and the plasticizer mixture of a preset weight B is sent to the stirring tank 3;

[0076] Step S4: adding a preset weight C of resin powder into the stirring tank 3 through the powder inlet of the stirring tank 3;
