Description

TECHNICAL FIELD

[0001] The utility model relates to automatic packaging technical field, concretely relates to controllable anti -alkali automatic packaging machine of unloading amount. BACKGROUND

[0002] Flake alkali is flaky alkali, and is widely used in multiple industries, for example, chemical industry, and often needs to be used in the production of various chemicals, such as soap, paper, textile treating agent, etc., and again, the production of many household and industrial cleaning agents also needs to use flake alkali.

[0003] In the production process of flake alkali, low-concentration dilute lye needs to be concentrated to form molten alkali, and then solidified to form solid alkali, and then the knife is used to cut the solid alkali into small pieces, and the produced flake alkali is sent into the automatic packaging machine for packaging, so as to facilitate the transportation and storage of flake alkali.

[0004] In the process of using the automatic packaging machine to package the flake alkali, part of the flake alkali often adheres to the inner wall of the packaging machine, thereby causing the packaging machine to be alkali, and however, due to the strong corrosiveness of the flake alkali, the packaging machine after alkali is easily corroded by the flake alkali and damaged, thereby affecting the service life of the packaging machine. UTILITY MODEL CONTENTS

[0005] The utility model intends to provide controllable anti -alkali automatic packaging machine of unloading amount, to prevent the packaging machine from alkali, and then avoid the problem of corrosion to the packaging machine.

[0006] In order to achieve the above object, the utility model adopts the following technical scheme: controllable anti -alkali automatic packaging machine of unloading amount, including the unloading box, the unloading box side is equipped with the feed inlet, the bottom of unloading box is equipped with the discharge port, the unloading box is equipped with the valve plate, the valve plate is equipped with two groups of symmetrical distribution, two groups of valve plates are located on the both sides of discharge port respectively, the upper end of valve plate is rotating end, rotating end is rotatably connected on the side wall of unloading box, the lower end of valve plate is swing end, valve plate is connected with the pneumatic cylinder, the pneumatic cylinder seat of pneumatic cylinder is rotatably arranged on the unloading box, the pneumatic cylinder rod of pneumatic cylinder is rotatably connected on the swing end of valve plate;The swing end of two groups of valve plates can be closed to the discharge port under the driving of pneumatic cylinder.

[0007] The principle and advantages of the present scheme are: in the present scheme, the valve plate is arranged to rotate in the discharging box, and the valve plate is driven by the cylinder, so that the valve plate can rotate and adjust the alkali output of the discharge port. At the same time, the valve plate acts as a movable side wall of the discharging box. In this way, the inclination of the valve plate can be changed to guide the caustic soda, and the caustic soda is not easy to accumulate on the inclined valve plate to cause caustic soda. At the same time, when part of the caustic soda adheres to the valve plate, the valve plate can be repeatedly swung by the cylinder to shake off the caustic soda. If the caustic soda adheres to the front wall or rear wall of the discharging box, the repeatedly moving valve plate can also rub against the front wall or rear wall to scrape off the adhered caustic soda. In this way, the purpose of preventing the packaging machine from being blocked by caustic soda is better achieved, and the use of the packaging machine is ensured.

[0008] Preferably, as an improvement, a retractable elastic plate is connected between the swinging end of the valve plate and the inner wall of the discharging box. The elastic plate, the valve plate and the inner wall of the discharging box form a sealed space. The connection between the cylinder and the valve plate is located in the sealed space.

[0009] Through the above scheme, the elastic plate is retractable, so as not to hinder the swinging movement of the valve plate. The elastic plate is used to seal the connection between the cylinder and the valve plate, so as to prevent caustic soda from entering the position and causing the cylinder and the connection between the cylinder and the valve plate to be stuck or corroded. The normal operation of the equipment is ensured, and the service life of the equipment is guaranteed.

[0010] Preferably, as an improvement, the elastic plate is a rubber plate or a silica gel plate.

[0012] Preferably, as an improvement, a cylindrical roller is arranged in the middle of the discharge port. The roller is fixedly installed on the inner wall of the discharging box. The roller is arranged parallel to the lower end of the valve plate. The swinging ends of the two valve plates can be abutted against the outer wall of the roller under the driving of the cylinder.

[0013] Through the above scheme, the roller is used to abut against the swinging end of the valve plate. When the two valve plates swing and close the discharge port, the swinging end is abutted against the side of the roller. In this way, it is not easy to produce gaps between the two valve plates or between the valve plate and the roller, so as to achieve the effect of better closing the discharge port. Compared with the scheme in which the swinging ends of the two valve plates directly abut against each other to close the discharge port, the present scheme can effectively prevent the gaps between the swinging ends of the two valve plates from leaking. At the same time, since the outer periphery of the roller is arc-shaped, the top of the roller is in an upwardly arched state, so that it is not easy for caustic soda to accumulate and remain on the roller.

[0015] Through the above scheme, the cleaning device is used for cleaning the packaging machine, which can further prevent the attached and residual tablet alkali from causing corrosion of the packaging machine. The cleaning pipe is used for connecting with a cleaning liquid source to send the cleaning liquid into the feeding box, and the spray pipe is used for connecting with the cleaning pipe and spraying the cleaning liquid sent by the cleaning pipe into the feeding box to achieve the purpose of cleaning the packaging machine.

[0016] Preferably, as an improvement, the spray pipe and the cleaning pipe are threadedly connected.

[0017] Through the above scheme, the spray pipe and the cleaning pipe are threadedly connected, which is more convenient for the maintenance of the cleaning device.

[0018] Preferably, as an improvement, the spray pipe has a connecting pipe fixedly connected with the cleaning pipe and a spray pipe head fixedly connected on the connecting pipe, and the spray pipe head is in the shape of a fan.

[0019] Through the above scheme, the spray pipe head is designed in the shape of a fan, so that the cleaning liquid can be sprayed in the shape of a fan when the spray pipe head sprays, thereby making the angle and range of spraying larger and being more conducive to fully cleaning the packaging machine.

[0020] Preferably, as an improvement, the spray pipe has a connecting pipe fixedly connected with the cleaning pipe and a flow guide fixedly connected on the connecting pipe, the flow guide has a connecting part in the shape of a cylinder and a flow guiding part in the shape of a cone, the connecting part is located in the connecting pipe and fixedly connected with the inner wall of the connecting pipe, the flow guiding part is located outside the connecting pipe and fixedly connected with the connecting part; the pipe opening of the connecting pipe away from the cleaning pipe is located above the flow guiding part.

[0021] Through the above scheme, the flow guide is used for guiding the cleaning liquid, when the cleaning liquid enters the connecting pipe from the cleaning pipe, it flows along the flow guide from the pipe opening of the connecting pipe, and is sprayed in a ring shape on the front and rear side walls and the two valve plates of the feeding box under the flow guiding action of the flow guiding part, so that the packaging machine can be more comprehensively and fully cleaned by spraying water from multiple angles, and the effect of preventing the packaging machine from being attached with alkali is better.

[0022] Preferably, as an improvement, a positioning plate is fixedly arranged in the connecting pipe, the connecting part penetrates through the positioning plate and is fixedly connected with the positioning plate, and a plurality of through holes are further arranged on the positioning plate, the through holes communicating the two sides of the positioning plate.

[0023] The positioning plate is used for mounting and fixing the connecting part and the flow guiding part, the through hole on the positioning plate is used for the flow of the cleaning liquid in the connecting pipe, and the cleaning liquid can be normally sprayed to clean the packaging machine.

[0024] Preferably, as an improvement, the connecting part is threadedly connected with the positioning plate.

[0025] Through the above scheme, by rotating the connecting part, the position of the connecting part fixed on the positioning plate can be changed, thereby adjusting the distance between the flow guiding part and the pipe opening of the connecting pipe, so as to change the spraying angle and range of the cleaning liquid.

[0041] Embodiment 3

[0042] The difference between the embodiment and embodiment 2 is only in the specific structure of the spray pipe. As shown in Figure 3 and Figure 4 The spray pipe in the embodiment has a connecting pipe 11 fixedly connected with the cleaning pipe 10 through screw threads and a flow guide 13 fixedly connected with the connecting pipe 11. As shown in Figure 4 The flow guide 13 has a connecting part 14 in the shape of a cylinder and a flow guide part 15 in the shape of a cone. The connecting part 14 is located in the connecting pipe 11 and is fixedly connected with the inner wall of the connecting pipe 11. The fixed connection between the connecting part 14 and the connecting pipe 11 is specifically as follows: a positioning plate 16 is fixedly arranged in the connecting pipe 11 by welding or clamping. The connecting part 14 penetrates through the positioning plate 16 and is fixedly connected with the positioning plate 16 through screw threads. The positioning plate 16 is further provided with a plurality of through holes 17, which communicate the upper and lower sides of the positioning plate 16.

The pipe opening of the connecting pipe 11 away from the cleaning pipe 10 (i.e., the lower end pipe opening shown in Figure 4 ).

[0043] The difference between the embodiment and embodiment 2 is only in the process of spray cleaning. The process of the embodiment in the specific implementation is as follows:

[0044] The cleaning liquid flows along the connecting pipe 11 and flows out through the pipe opening (i.e. the lower end pipe opening shown in the figure) of the connecting pipe 11 away from the cleaning pipe 10. Since the flow guide part 15 is conical, the flow guide part 15 guides the flow of the cleaning liquid, so that the cleaning liquid is sprayed in a ring shape to all directions and sprayed into the hopper 1. In this way, the front and rear sidewalls of the hopper 1 and the two valve plates 4 can be cleaned at the same time, and the cleaning is more complete and comprehensive. It can be understood that, in order to ensure the cleaning effect, the diameter of the pipe opening (i.e. the lower end pipe opening shown in the figure) of the connecting pipe 11 away from the cleaning pipe 10 is smaller than the diameter of the bottom end of the flow guide part 15, so that the cleaning liquid flowing out of the connecting pipe 11 can flow to the upper surface of the flow guide part 15 and be guided and changed in flow direction.
