Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically a dryer powder cake counting device. Background Technology

[0002] A powder cake dryer is a device used to dry powder cakes and shape them. Generally, powder cake dryers are equipped with a conveying device that can drive multiple rows of mesh frames to circulate through the drying area of ​​the dryer. Each mesh frame has multiple ring-shaped iron bowls inside. Powder of appropriate size is put into the iron bowls by manual weighing. Then, each row of mesh frames circulates through the drying process in turn, so that the powder cake inside the iron bowl is dried and shaped. However, when using the dryer, the powder is usually weighed and placed into the iron bowl manually. The iron bowl near the middle of the machine may be missed due to human error, making it difficult to count the actual number of powder cakes produced in real time, which is quite inconvenient. In addition, some dryers are equipped with a hot pressing and shaping device to press the powder into a round cake shape and dry it. This can easily cause some powder to get stuck inside the iron bowl after being pressed and dried, making it difficult to fall off naturally. The powder cake may also re-enter the drying area with the conveyor device, resulting in secondary drying, which is also inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a powder cake counting device for a dryer to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A powder cake counting device for a dryer, comprising: The machine body comprises a U-shaped frame, a box for receiving powder compacts, and a material discharge mechanism for assisting in the unloading of powder compacts. Rectangular holes are provided on opposite sides of the machine body. The U-shaped frame is fixedly connected to the machine body, and multiple photoelectric switches are fixedly connected to the bottom surface of the U-shaped frame. The box is located on one side of the machine body, and the material discharge mechanism is located inside the machine body. The material discharge mechanism includes a plate, with both ends of the plate fixedly connected to the inside of two rectangular holes. Multiple sleeve holes are provided on the top surface of the plate, and a connecting pipe is rotatably fitted onto the inner sidewall of any sleeve hole. An air inlet pipe is fixedly connected to the top of any connecting pipe, and an air pump is provided with the air inlet pipe.

[0005] Furthermore, each connecting pipe has a circular shell fixedly connected to its bottom surface, and each circular shell has multiple nozzles fixedly connected to its bottom surface.

[0006] Furthermore, the top surface of the plate is fixedly connected to a guide rail, and a rack is slidably engaged inside the guide rail. A toothed ring is fixedly sleeved on the outer wall of each of the multiple connecting pipes, and the teeth on any one of the toothed rings mesh with the teeth on the rack.

[0007] Furthermore, the machine body is fixedly connected to an electric push rod, and the movable end of the electric push rod is fixedly connected to one end of the rack.

[0008] Furthermore, each of the circular shells has a connecting block fixedly connected to its outer side wall, a rebound spring fixedly connected to the bottom surface of each connecting block, a stop plate fixedly connected to the bottom end of each rebound spring, and multiple protrusions fixedly connected to the bottom surface of each stop plate.

[0009] Furthermore, multiple support straps are fixedly connected between the two opposite inner sidewalls of the box, and each support strap is arranged at an angle.

[0010] Furthermore, each connecting block has a circular hole on its top surface, each abutment plate has a fixed limit rod on its top surface, and each limit rod is slidably sleeved inside an adjacent circular hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The photoelectric switch on the U-shaped frame detects the passing iron bowls, thus recording the total production. When the iron bowl passes under the plate 410, the air pump is activated to spray gas from nozzles on multiple circular shells, blowing the powder cakes inside the iron bowls off. At the same time, the electric push rod is activated to drive the rack to move back and forth, causing the rack to drive multiple connecting pipes and circular shells to rotate back and forth through multiple toothed rings. This causes multiple connecting blocks to rotate back and forth with adjacent circular shells, causing the protrusions on multiple abutments to scrape the mesh frame, thus causing the mesh frame to vibrate and facilitating the falling of the powder cakes inside the iron bowls, thereby facilitating the unloading of the powder cakes.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 In this embodiment of the present invention, a powder cake counting device for a dryer includes: The machine body 100, U-shaped frame 200, box 300 capable of receiving powder compacts, and material discharge mechanism 400 capable of assisting in unloading powder compacts are provided. Rectangular holes are provided on both sides of the machine body 100. The U-shaped frame 200 is fixedly connected to the machine body 100. Multiple photoelectric switches are fixedly connected to the bottom surface of the U-shaped frame 200. The box 300 is located on one side of the machine body 100. The material discharge mechanism 400 is located inside the machine body 100. The material discharge mechanism 400 includes a plate 410. The two ends of the plate 410 are fixedly connected to the inside of two rectangular holes, and multiple sleeve holes are provided on the top surface of the plate 410. A connecting pipe 420 is rotatably sleeved on the inner side wall of any sleeve hole. An air inlet pipe is fixedly connected to the top of any connecting pipe 420. An air pump is provided with the air inlet pipe.

[0016] Specifically, the number of photoelectric switches on the U-shaped frame 200 is equal to the number of iron cups in each row on the machine body 100. When each row of iron cups on the machine body 100 passes the photoelectric switches sequentially, the photoelectric switch will detect a powder compact if it is in the powder lid, and will not detect a powder compact if it is not in the lid. The photoelectric switches are equipped with a PLC controller and data storage device. The photoelectric switch that detects a powder compact transmits a signal to the PLC via a wire. The PLC counts the photoelectric signals according to a preset program and records them through the data storage device. The system records the number of powder cakes produced, allowing for real-time and accurate counting. When a powder cake gets stuck in the iron bowl, the air inlet pipe can be connected to the air pump via a multi-port connector after the iron bowl passes the plate 410. The air pump is then activated to spray air from the connecting pipe 420, blowing the powder cake from the iron bowl into the housing 300, thus facilitating the powder cake's discharge. The number of connecting pipes 420 on the plate 410 is equal to the number of iron bowls in each row. The multi-port connector, air pump, photoelectric switch, PLC controller, control program, and data storage device are all existing technologies and will not be described in detail here. Example

[0017] like Figure 2-3As shown, in this embodiment, a circular shell 430 is fixedly connected to the bottom surface of any connecting pipe 420, and multiple nozzles are fixedly connected to the bottom surface of any circular shell 430. A guide rail 450 is fixedly connected to the top surface of the plate 410, and a rack 451 is slidably engaged inside the guide rail 450. A toothed ring 421 is fixedly sleeved on the outer wall of each of the multiple connecting pipes 420, and the teeth on the upper gear of any toothed ring 421 mesh with the teeth on the upper gear of the rack 451. An electric push rod 460 is fixedly connected to the machine body 100, and the movable end of the electric push rod 460 is fixedly connected to one end of the rack 451. A connecting block 440 is fixedly connected to the outer wall of any circular shell 430, a rebound spring 441 is fixedly connected to the bottom surface of any connecting block 440, a stop plate 442 is fixedly connected to the bottom end of any rebound spring 441, and multiple protrusions are fixedly connected to the bottom surface of any stop plate 442.

[0018] In this embodiment, after the gas enters the connecting pipe 420, it can be sprayed out from the nozzle on the adjacent circular shell 430, thereby expanding the range of the sprayed airflow. This makes it easier for the powder cake inside the iron bowl to be blown off by the airflow. By activating the electric push rod 460 to move back and forth, the electric push rod 460 drives the rack 451 to move back and forth, thereby causing the rack 451 to drive multiple connecting pipes 420 and circular shells 430 to rotate back and forth through the toothed ring 421. The abutment plate 442 on the circular shell 430 can scrape against the passing mesh frame, causing the protrusions on the abutment plate 442 to scrape the mesh of the mesh frame, thereby causing the mesh frame to vibrate, making it easier for the powder cake inside the iron bowl to fall off.

[0019] like Figure 4 As shown, in this embodiment, multiple support straps 310 are fixedly connected between the two opposite inner sidewalls of the box 300, and each support strap 310 is arranged at an angle.

[0020] In practice, the support strap 310 is in a relaxed state. The support strap 310 can be made of rubber or silicone. After the powder compact falls from the iron bowl, it can be caught by the support strap 310 first. Then, due to the tilt angle of the support strap 310, the powder compact on the support strap 310 will naturally fall from the support strap 310 into the housing 300. In this way, the support strap 310 pre-catches the powder compact, reducing the possibility of breakage that may occur if the powder compact falls directly. Example

[0021] Based on Embodiment 1, the limiting rod 443 is set to prevent the abutment plate 442 from tilting.

[0022] like Figure 3 As shown, in this embodiment, a circular hole is provided on the top surface of any connecting block 440, and a limiting rod 443 is fixedly connected to the top surface of any abutment plate 442. Each limiting rod 443 is slidably sleeved inside the adjacent circular hole.

[0023] In practice, the adjacent abutment plate 442 is limited by the limiting rod 443, so that when the protrusion on the abutment plate 442 scrapes against the mesh of the mesh frame and vibrates, the abutment plate 442 is not easy to tilt and the protrusion is kept in contact with the mesh frame.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0025] Each connecting block 440 has a rebound spring 441 fixedly connected to its bottom surface. Each rebound spring 441 has a stop plate 442 fixedly connected to its bottom end. Each stop plate 442 has multiple protrusions fixedly connected to its bottom surface.

[0026] In this embodiment, after the gas enters the connecting pipe 420, it can be sprayed out from the nozzle on the adjacent circular shell 430, thereby expanding the range of the sprayed airflow. This makes it easier for the powder cake inside the iron bowl to be blown off by the airflow. By activating the electric push rod 460 to move back and forth, the electric push rod 460 drives the rack 451 to move back and forth, thereby causing the rack 451 to drive multiple connecting pipes 420 and circular shells 430 to rotate back and forth through the toothed ring 421. The abutment plate 442 on the circular shell 430 can scrape against the passing mesh frame, causing the protrusions on the abutment plate 442 to scrape the mesh of the mesh frame, thereby causing the mesh frame to vibrate, making it easier for the powder cake inside the iron bowl to fall off.

After the powder compact falls from the iron bowl, it can be caught by the support strap 310 first. Then, due to the tilt angle of the support strap 310, the powder compact on the support strap 310 will naturally fall from the support strap 310 into the housing 300. In this way, the support strap 310 pre-catches the powder compact, reducing the possibility of breakage that may occur if the powder compact falls directly. Example

[0029] Based on Embodiment 1, the limiting rod 443 is set to prevent the abutment plate 442 from tilting.

[0030] like Figure 3As shown, in this embodiment, a circular hole is provided on the top surface of any connecting block 440, and a limiting rod 443 is fixedly connected to the top surface of any abutment plate 442. Each limiting rod 443 is slidably sleeved inside the adjacent circular hole.

[0031] In practice, the adjacent abutment plate 442 is limited by the limiting rod 443, so that when the protrusion on the abutment plate 442 scrapes against the mesh of the mesh frame and vibrates, the abutment plate 442 is not easy to tilt and the protrusion is kept in contact with the mesh frame.
