[0002] A tinplate can refers to a can made of tinplate. Tinplate cans are widely used in the field of food packaging, such as tea cans, biscuit cans, candy cans, canned foods, etc. When the current tinplate can seaming machine is running, when the number of can bodies on the conveyor belt is insufficient and the weight is not enough to make the friction between the conveyor belt and the can body push the can body forward, the gap of the feeding screw for the can does not fit with the can body, resulting in can clamping, which can deform the can body, increase the loss rate of the can body, and a special person needs to be arranged at the can feeding place to manually stop the machine to take out the deformed can body and put on a normal can body. It is also necessary to adjust the timing and position of the tinplate can entering the can in real time. If the operation is improper, it may even squeeze the fingers of the operator, and the practicability and protection are insufficient and need to be improved. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] By providing an anti-pinch device for the body of a tinplate can during can feeding, the embodiment of the present application effectively solves the technical problems of the existing device being insufficient in practicality and protection. By setting an infrared sensing module, when the number of tinplate can bodies on the can body conveying assembly is insufficient, the can blocking baffle in the can blocking module will automatically pop out to block the tinplate can body until the number of tinplate can bodies accumulates to a sufficient amount so that the friction between the can body conveying assembly and the tinplate can body can push the tinplate can body forward. When the infrared sensing module senses that there is a tinplate can body on the feeding conveying assembly, it will then control the can blocking baffle in the can blocking module to retract and release, thereby enabling real-time adjustment of the friction between the tinplate can body and the can body conveying assembly according to the situation, avoiding the situation where the gap of the feeding propelling screw does not fit with the tinplate can body and causing the tinplate can body to be deformed, thus reducing the loss rate of the tinplate can body, improving practicality, and by setting an anti-pinch structure, it can avoid the staff from stopping the machine to take out the deformed tinplate can body, so as to improve work efficiency. At the same time, it can also avoid the problem of the staff squeezing their fingers due to improper operation when taking out the deformed tinplate can body, thereby improving protection.

[0021] Embodiment

[0022] As Figure 1 shown, the technical solution in the embodiment of the present application effectively solves the technical problems of the existing device being insufficient in practicality and protection. The general idea is as follows:

[0023] In view of the problems existing in the prior art, the present utility model provides an anti-pinch device for the body of a tinplate can during can feeding, including a can body conveying assembly 11 and a feeding conveying assembly 12. The feeding conveying assembly 12 is arranged on the side wall of the can body conveying assembly 11, and the conveyor belts of the can body conveying assembly 11 and the feeding conveying assembly 12 are parallel.

[0024] An anti-pinch structure is arranged on the side wall of the can body conveying assembly 11.

[0025] The anti-pinch tank structure includes an infrared sensing module 13. The infrared sensor of the infrared sensing module 13 is a photoelectric induction type. A tank blocking module 14 is provided on the side wall of the incoming tank conveying assembly 12. A tank blocking baffle 15 is fixedly installed on the output shaft of the tank blocking module 14. The infrared sensing module 13 is connected to the bracket of the tank body conveying assembly 11 by screws. The tank blocking module 14 is on the same side as the infrared sensing module 13. The tank blocking module 14 is connected to the bracket of the incoming tank conveying assembly 12 by screws. The tank blocking baffle 15 is slidably installed with the bracket of the incoming tank conveying assembly 12. The tank blocking baffle 15 is located above the conveyor belt of the incoming tank conveying assembly 12. By setting the infrared sensing module 13, when the number of iron tank body 19 on the tank body conveying assembly 11 is insufficient, the tank blocking baffle 15 in the tank blocking module 14 will automatically pop out to block the iron tank body 19 until the iron tank body 19 accumulates to a sufficient number so that the friction between the tank body conveying assembly 11 and the iron tank body 19 can push the iron tank body 19 forward. The infrared sensing module 13 senses that there is an iron tank body 19 on the incoming tank conveying assembly 12, and then controls the tank blocking baffle 15 in the tank blocking module 14 to retract and release, so that the friction between the iron tank body 19 and the tank body conveying assembly 11 can be adjusted in real time according to the situation, avoiding the situation that the gap of the incoming tank propulsion screw 18 does not fit with the iron tank body 19 and causing the iron tank body 19 to deform, reducing the loss rate of the iron tank body 19. At the same time, it can also prevent the staff from stopping the machine to take out the deformed iron tank body 19 to improve work efficiency. At the same time, it can also avoid the problem that the staff may squeeze their fingers due to improper operation when taking out the deformed iron tank body 19, thus improving the practicability and protection.

[0026] A signal processing module 16 is provided between the tank blocking module 14 and the infrared sensing module 13 (the signal processing module 16 is mainly composed of a PLC controller. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations inside it, and controls various types of mechanical equipment or production processes through digital or analog inputs and outputs). A delay knob 17 is provided inside the signal processing module 16. An incoming tank propulsion screw 18 is provided on the side wall of the incoming tank conveying assembly 12 away from the tank blocking module 14. The incoming tank propulsion screw 18 is in a communicating state with the incoming tank conveying assembly 12 on one side of the incoming tank propulsion screw 18. Multiple iron tank bodies 19 are provided on the synchronous belts of the tank body conveying assembly 11 and the incoming tank conveying assembly 12. By setting the signal processing module 16, the signal processing module 16 can complete the control of the infrared sensing module 13 and the tank blocking module 14, which is beneficial to subsequent control. At the same time, the output parameters of the infrared sensing module 13 and the tank blocking module 14 can also be adjusted according to the actual use situation, having high scalability.

[0027] Working principle:

[0028] First step, during use, an infrared sensing module 13 needs to be installed at the end position of the appropriate cumulative quantity length of the iron can body 19 preset on the can body conveying assembly 11. When the infrared sensing module 13 senses that there is a can body on the can body conveying assembly 11, the signal processing module 16 adjusts the release timing of the can blocking baffle 15 in the can blocking module 14 according to the delay adjustment set in advance by the delay knob 17, so that the can blocking module 14 retracts the can blocking baffle 15, enabling the released iron can body 19 to just pass through the incoming can conveying assembly 12 and enter the fitting position of the incoming can propulsion screw 18;

[0029] Second step, when the quantity of the iron can body 19 on the can body conveying assembly 11 is insufficient, at this time, the can blocking baffle 15 in the can blocking module 14 will automatically pop out to block the iron can body 19 until the quantity of the iron can body 19 accumulates enough so that the friction between the can body conveying assembly 11 and the iron can body 19 can push the iron can body 19 forward. When the infrared sensing module 13 senses that there is an iron can body 19 on the incoming can conveying assembly 12, it then controls the can blocking baffle 15 in the can blocking module 14 to retract and release.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
