Description

Technical Field

[0001] This utility model relates to a device for cleaning and drying the outer surface of a tray container. Background Technology

[0002] In the pharmaceutical, health product, and oral liquid manufacturing industries, small-capacity glass bottles are prone to becoming contaminated with liquid or other impurities during filling and sterilization. If these stains are not properly removed, they can interfere with the subsequent labeling process and negatively impact the product's appearance. Therefore, products must be cleaned and dried after filling and sealing.

[0003] In existing technologies, most manufacturers use the following process: workers manually place trays of sorted products into a large cleaning tank filled with water at 50-60 degrees Celsius. The workers then agitate the trays of products in the tank for a certain period before removing them and placing them in a designated location to stand for a set time to achieve cleaning and drying. However, this traditional method has many drawbacks. On the one hand, the long hours and high intensity of labor result in low production efficiency, inconsistent cleaning effects, and difficulty in ensuring consistent product quality. On the other hand, prolonged exposure to high-temperature water increases the risk of safety accidents for workers. Utility Model Content

[0004] The first objective of this invention is to provide a device for cleaning the outer surface of tray containers, so as to achieve fully mechanical cleaning of the impurities adhering to the outer surface of tray containers after filling and sterilization; the second objective is to provide a drying machine that uses the above-mentioned device for cleaning the outer surface of tray containers, so as to achieve automation, cleaning and drying of tray containers.

[0005] To achieve the first objective mentioned above, this invention proposes a device for cleaning the outer surface of a tray-type container, comprising a heated cleaning tank, a water agitation mechanism, and a tray clamping device. The tray clamping device is installed inside the heated cleaning tank and is driven by a lifting cylinder to move vertically up and down within the heated cleaning tank. The tray clamping device clamps the material tray and the container to be cleaned within the material tray from both the upper and lower sides. A flushing hole for water supply is provided on the upper clamping plate of the tray clamping device that contacts the container to be cleaned. A water agitation mechanism is installed on the tray clamping device above the upper clamping plate. The water agitation mechanism moves up and down below the water surface, causing the water in the heated cleaning tank to flow rapidly. The water is forced into the clamping area from the flushing hole, forming a high-speed water flow that flushes the outer wall of the container to be cleaned within the material tray at high speed. In the initial state, the tray clamping device is above the surface of the heated cleaning tank; in the working state, the lifting cylinder drives the water agitation mechanism and the tray clamping device to be below the liquid surface of the heated cleaning tank.

[0006] In this embodiment, the width of the flushing hole on the upper clamping plate is smaller than the opening of the container to be cleaned, but larger than the gap formed after adjacent containers to be cleaned are arranged.

[0007] In this embodiment, the material tray clamping device includes an upper fixed frame, a lower fixed frame, and an upper side clamping plate arranged in parallel to each other. The upper fixed frame and the lower fixed frame are fixedly connected by guide rods arranged vertically at the four corners. The four corners of the upper side clamping plate are slidably fitted onto the guide rods. A clamping cylinder is fixed on the upper fixed frame, and the movable end of the clamping cylinder is fixedly connected to the upper side clamping plate through a connecting block. A clamping area is formed between the upper side clamping plate and the lower fixed frame. In the initial state, the height of the clamping area is greater than the overall height of the material tray containing the container to be cleaned. One side of the clamping area is the inlet, and the other side is the outlet.

[0008] In this embodiment, a feeding detection sensor is provided in the clamping area, and a clamping detection sensor is provided on the clamping cylinder. The feeding monitoring sensor is used to detect whether the material tray is placed in the clamping area and moved into place, and the clamping detection sensor is used to monitor whether the clamping stroke of the clamping cylinder is in place.

[0009] In this embodiment, the heated cleaning tank is also equipped with a water inlet, a drain outlet, an overflow outlet, a lower liquid level sensor, and an upper liquid level sensor. The water inlet is used to inject water into the heated cleaning tank, and the drain outlet is used to discharge the water from the heated cleaning tank. When the lower liquid level sensor detects water in the heated cleaning tank, the heating system starts working and heats the water to the set temperature. When the upper liquid level sensor detects water, the water inlet stops injecting water. When the lower liquid level sensor detects no water, the water inlet injects water again. The overflow outlet is located above the upper liquid level sensor, and automatic drainage is achieved when the water level exceeds the overflow outlet.

[0010] In this embodiment, the water agitation mechanism includes a tapping plate and a driving cylinder. A support plate is fixed on the upper fixed frame, and a vertically arranged driving cylinder is provided on the support plate. The tapping plate is located directly above the upper clamping plate and is arranged parallel to the upper clamping plate, and the tapping plate covers the clamping area. The tapping plate is connected to the movable end of the driving cylinder.

[0011] In this embodiment, the material tray has an opening facing upwards, and the bottom plate and side walls of the material tray are covered with permeable holes. The material tray is filled with containers to be cleaned, with the openings of the containers facing upwards. The height of the containers to be cleaned is greater than the depth of the material tray. When the height of the containers to be cleaned is less than the depth of the material tray, a permeable plate is placed on one side of the opening of the containers to be cleaned, so that the overall height of the permeable plate and the containers to be cleaned is greater than the depth of the material tray. The permeable plate is covered with permeable holes.

[0012] In this embodiment, an opening on one side wall of the material tray forms an inlet / outlet for conveniently pushing multiple containers to be cleaned into the material tray at once. A movable baffle matching the size of the inlet / outlet is movably fitted onto the inlet / outlet of the material tray. Connecting plates are fixed to both sides of the movable baffle. The movable baffle is hinged to the side walls on both sides of the inlet / outlet via the connecting plates. The connecting plates are hinged to the side walls using a freely adjustable damping hinge. The bottom plate of the material tray protrudes outward from the side wall at least on the side closest to the inlet / outlet to form a retaining edge. In the washing and spin-drying state, the movable baffle is positioned at the location of the material tray's inlet / outlet to close the inlet / outlet. At this time, the bottom of the movable baffle is supported on the baffle plate. In the feeding state, the movable baffle flips upward, opening the material tray's inlet / outlet.

[0013] In this embodiment, an opening on one side wall of the material tray forms an inlet / outlet that facilitates the simultaneous insertion of multiple containers to be cleaned into the material tray. The inlet / outlet of the material tray is provided with slots, and the size of the insert plate matches the size of the inlet / outlet. During the washing and spin-drying state, the insert plate is inserted into the slot to close the inlet / outlet of the material tray; during the feeding state, the insert plate is pulled out of the slot to open the inlet / outlet of the material tray.

[0014] To achieve the second objective mentioned above, the present invention proposes an integrated drying machine, including the aforementioned tray container outer surface cleaning device and a rotary dehydration device. The inlet of the rotary dehydration device is connected to the discharge port of the clamping area of ​​the tray container outer surface cleaning device. The rotary dehydration device is used to drive the material tray and the container to be cleaned in the material tray to rotate and achieve the spin-drying of the container to be cleaned.

[0015] In this embodiment, the rotary dehydration device includes a dehydration tank, a dehydration limiting frame and a central rotating mechanism installed in the dehydration tank. The rotating shaft of the central rotating mechanism is arranged horizontally, and multiple dehydration limiting frames are evenly arranged around the rotating shaft. A dehydration zone is provided in the dehydration limiting frame. The height of the dehydration zone matches the total height of the material tray and the container to be cleaned in the material tray. The inlet of the dehydration zone is connected to the outlet of the clamping zone.

[0016] In this embodiment, the dehydration limiting frame includes an upper limiting frame, a lower limiting frame, and fixing rods. The upper limiting frame and the lower limiting frame are arranged parallel to each other and are connected to each other as a whole by fixing rods set at the four corners. The dehydration zone is formed between the upper limiting frame and the lower limiting frame, and the opposite sides of the upper limiting frame and the lower limiting frame constitute the inlet and outlet of the dehydration zone, respectively. The upper limiting frame and the lower limiting frame are arranged parallel to the rotation axis, and the rotation axis is driven to rotate by a driving device.

[0017] In this embodiment, both the tray container outer surface cleaning device and the rotary dewatering device are mounted on a frame. The frame also includes an inlet tray conveying track, an outlet tray conveying track, and a control console. The outlet end of the inlet tray conveying track is connected to the feed inlet of the clamping area. A horizontally arranged inlet tray cylinder is also installed on the frame at the outlet end of the inlet tray conveying track. The inlet tray cylinder is used to push the material tray on the inlet tray conveying track into the clamping area. The outlet of the dewatering area of ​​the rotary dewatering device is connected to the inlet of the outlet tray conveying track. A horizontally arranged outlet tray cylinder is provided on the frame on the side opposite to the discharge port of the clamping area. The outlet tray cylinder is used to push the material tray in the clamping area into the dewatering area. The control console is equipped with a controller, which is connected to the inlet tray cylinder, the outlet tray cylinder, the tray container outer surface cleaning device, and the rotary dewatering device.

[0018] With the above structure, this utility model has the following advantages:

[0019] 1. This utility model includes a tray container outer surface cleaning device. Through the cooperation of a tray clamping device, a water agitation mechanism and various cylinders, it simulates manual action to achieve automated cleaning and reduce labor costs. The water agitation mechanism generates a high-speed water flow in the heated cleaning tank to flush the outer wall of the container. At the same time, in conjunction with the water inlet and outlet, heating and liquid level sensor system in the heated cleaning tank, it accurately controls the water temperature and water level, and improves the cleaning effect of the outer surface of the container without affecting the filling material inside the container.

[0020] 2. This utility model also includes an integrated drying machine, which utilizes a tray container outer surface cleaning device and a rotary dehydration device to quickly dry the water on the outside of the bottle after cleaning. Specifically: the tray container outer surface cleaning device ensures the cleaning effect on the outer surface of the container, and while the container is being cleaned in the heated cleaning tank, the hot water conducts heat to the outer wall of each container. Then the tray containers enter the rotary dehydration device, where centrifugal force is used to dry the residual water on the outer wall of the container. At the same time, the residual heat on the container body is used to evaporate the water, thus completing the entire cleaning and drying process. This device also works in conjunction with the tray inlet and outlet conveyor tracks and the control console to realize automatic material tray conveying and control, with a smooth and efficient operation process.

[0021] In summary, this utility model enables automated production with high capacity and efficiency, typically achieving a cleaning speed of 600 pieces per minute while ensuring the cleaning effect of the products. It also reduces the labor intensity of workers, saves labor costs, and significantly reduces the production costs of enterprises. Attached Figure Description

[0034] 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.

[0035] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0036] like Figures 2 to 4 As shown, a device for cleaning the outer surface of a tray container includes a heated cleaning tank 41, a water agitation mechanism 42, and a tray clamping device 43. The tray clamping device 43 is installed inside the heated cleaning tank 41 and is driven to move vertically up and down within the heated cleaning tank 41 by a lifting cylinder 44 installed inside the heated cleaning tank 41. The tray clamping device 43 is used to clamp the material tray 9 and the container 8 to be cleaned inside the material tray 9 from the upper and lower sides. The tray container refers to the container 8 to be cleaned placed inside the material tray 9. In this embodiment, the container 8 to be cleaned is a small-capacity glass bottle after being filled with products. Small-capacity glass bottles are generally used in pharmaceutical factories as containers for holding pharmaceutical liquids, health products, or oral liquids.

[0037] A flushing hole 4351 for water supply is provided on the upper clamping plate 435 of the material tray clamping device 43 at the position corresponding to the clamping area where the material tray 9 is located. A water agitation mechanism 42 is installed above the upper clamping plate 435 of the material tray clamping device 43. The water agitation mechanism 42 moves up and down below the water surface, causing the water in the heated cleaning tank to flow rapidly. The water is forced into the clamping area through the flushing hole 4351, thereby forming a high-speed water flow that flushes the outer wall of the container 8 to be cleaned in the material tray 9 at high speed. In the initial state, the material tray clamping device 43 is above the water surface of the heated cleaning tank 41. In the working state, the lifting cylinder 44 drives the water agitation mechanism 42 and the material tray clamping device 43 to be below the water surface of the heated cleaning tank 41. With the above structure, the water agitation mechanism 42 not only simulates the action of manually shaking the material tray 9 in the water tank, thus completely replacing manual action and realizing automated production, but also ensures that the container 8 to be cleaned can be completely immersed in the water in the heated cleaning tank 41. The water temperature in the heated cleaning tank 41 is determined according to the material of the container 8 to be cleaned and the product inside the container 8. For example, if the container 8 to be cleaned is a small-capacity glass bottle after being filled with product, water at about 50-60℃ can be used for cleaning. Furthermore, the water agitation mechanism 42 makes the water flow rapidly, forcing the water from the flushing hole 4351 into the clamping area, thereby forming a high-speed water flow that flushes the outer wall of the container 8 to be cleaned in the material tray 9 at high speed, ensuring the stability of the product cleaning effect and reducing the company's labor costs.

[0038] like Figure 5 As shown, in this embodiment, the flushing hole 4351 on the upper clamping plate 435 is a waist-shaped hole. The width of the flushing hole 4351 is smaller than the opening of the container 8 to be cleaned and larger than the gap formed after the adjacent containers 8 to be cleaned are arranged.

[0039] like Figure 2As shown, the material tray clamping device 43 includes an upper fixed frame 432, a lower fixed frame 436, and an upper clamping plate 435 arranged parallel to each other. The upper fixed frame 432 and the lower fixed frame 436 are fixedly connected by guide rods 434 arranged vertically at the four corners. The four corners of the upper clamping plate 435 are slidably fitted onto the guide rods 434. A clamping cylinder 431 is fixed on the upper fixed frame 432. The movable end of the clamping cylinder 431 is fixedly connected to the upper clamping plate 435 through a connecting block 433. The clamping area is formed between the upper clamping plate 435 and the lower fixed frame 436. In the initial state, the height of the clamping area is greater than the overall height of the material tray 9 containing the container 8 to be cleaned. One side of the clamping area is the feed inlet, and the other side is the discharge outlet. The lower fixed frame 436 is provided with a guide baffle 437 at the feed inlet. The guide baffle 437 is used to guide the material tray 9 from the feed inlet to the clamping area. A feed detection sensor 46 is provided in the clamping area, and a clamping detection sensor 45 is provided on the clamping cylinder 431. The feed detection sensor is used to detect whether the material tray 9 is placed in the clamping area and moved into place, and the clamping detection sensor 45 is used to monitor whether the clamping stroke of the clamping cylinder 431 is complete.

[0040] The water agitation mechanism 42 includes a tapping plate 423 and a drive cylinder 421. A support plate 422 is fixed on the upper fixed frame 432. The drive cylinder 421 is vertically arranged on the support plate 422. The tapping plate 423 is arranged parallel to the upper clamping plate 435 and covers the clamping area. The tapping plate 423 is connected to the movable end of the drive cylinder 421.

[0041] The upper fixed frame 432 and the connecting block 433, the support plate 422 and the patting plate 423, and the heating cleaning tank 41 and the material tray clamping device 43 are respectively provided with guide mechanisms arranged parallel to the movement paths of the clamping cylinder 431, the driving cylinder 421 and the lifting cylinder 44. The guide mechanisms are used to ensure the stability of the upper clamping plate 435, the patting plate 423 and the material tray clamping device 43 during movement.

[0042] like Figure 2 As shown, the heated cleaning tank 41 is also equipped with a water inlet, a drain outlet, an overflow outlet, a heating system 411, a lower liquid level sensor 412, and an upper liquid level sensor 413; the heating system 411 can use heating pipes or steam coils as the main heating element and heating pipes as auxiliary heating elements; the purpose of the heating system 411 is to heat the water to quickly reach the set temperature.

[0043] Using the above structure, firstly, water is injected into the heated cleaning tank 41 through the water inlet. When the lower liquid level sensor 412 in the heated cleaning tank 41 detects water, the heating system 411 starts working and heats the water to the set temperature. When the upper liquid level sensor 413 detects water, the water inlet stops injecting water. The overflow port is located above the upper liquid level sensor 413, and automatic drainage is achieved when the water level exceeds the overflow port. When the lower liquid level sensor 412 detects no water, water is injected into the water inlet again.

[0044] The material tray 9 is pushed into the clamping area of ​​the material tray clamping device 43. After the feeding detection sensor 46 detects that the material tray 9 is in place, the upper clamping plate 435, driven by the clamping cylinder 431, presses the material tray 9 and the container 8 to be cleaned inside the material tray 9 together. After the clamping detection sensor 45 detects that the clamping is in place, it controls the lifting cylinder 44 to move the material tray clamping device 43 and the water agitation mechanism 42 downward to the set position, so that the material tray clamping device 43 and the water agitation mechanism 42 are all below the water surface. At this time, the driving cylinder 421 is activated, driving the beater plate 423 to move up and down. By setting, the lifting cylinder 44 can also move the material tray clamping device 43 and the water agitation mechanism 42 up and down at the same time as the driving cylinder 421, thereby agitating the water in the entire cleaning tank and continuously generating water flow shock waves to continuously rinse the outer surface of the container 8 to be cleaned inside the material tray 9, ultimately achieving the purpose of thoroughly cleaning all surfaces of the container 8 to be cleaned.

[0045] like Figure 1 As shown, the present invention also includes an integrated drying machine. Specifically, the integrated drying machine includes the above-mentioned tray container outer surface cleaning device 4 and rotary dehydration device 5. The inlet of the rotary dehydration device 5 is connected to the discharge port of the clamping area of ​​the tray container outer surface cleaning device 4. The rotary dehydration device 5 is used to drive the material tray and the container to be cleaned in the material tray to rotate at high speed (≥300 rpm) to achieve high-speed spin drying of the container to be cleaned.

[0046] like Figure 6 , 7As shown, the rotary dehydration device 5 includes a dehydration tank 56, a dehydration limiting frame and a central rotating mechanism 54 installed in the dehydration tank 56. The rotating shaft 541 of the central rotating mechanism 54 is horizontally arranged. Multiple dehydration limiting frames are evenly arranged around the rotating shaft 541 to achieve natural dynamic balance of the material. In this embodiment, two dehydration limiting frames are arranged. A dehydration zone is provided inside the dehydration limiting frame. The height of the dehydration zone matches the total height of the material tray 9 and the container 8 to be cleaned inside the material tray 9. The inlet of the dehydration zone is connected to the outlet of the clamping zone. The opening of the dehydration tank 56 faces upward. A transparent sealing cover is provided on the opening of the dehydration tank 56. When the rotary dehydration device 5 is working, the sealing cover is closed to reduce the risk during dehydration. Using the above structure, the container 8 to be cleaned, which has been cleaned in the heated cleaning tank 41 and is still warm, is sent to the rotary dehydration device 5. In this way, on the one hand, the residual water on the outer wall of the container 8 is brushed off by spin drying, and on the other hand, the remaining water on the outer wall of the container 8 is evaporated by the residual heat of the container 8. Through the cooperation of the heated cleaning tank 41 and the rotary dehydration device 5, the water residue on the outer wall of the container 8 is greatly reduced.

[0047] The dehydration limiting frame includes an upper limit frame 51, a lower limit frame 52, and fixing rods 53. The upper limit frame 51 and the lower limit frame 52 are arranged parallel to each other and are connected to each other as a whole by fixing rods 53 set at the four corners. Guide plates 55 arranged parallel to the rotation axis 541 are fixed on both sides of the lower limit frame 52. The distance between the two guide plates 55 matches the width or length of the material tray. The distance between the upper limit frame 51 and the lower limit frame 52 matches the total height of the material tray 9 and the container 8 to be cleaned inside the material tray 9. The upper limit frame 51, the lower limit frame 52, and the two guide plates enclose the dehydration zone. The two guide plates 55 form a funnel-shaped opening at the inlet of the dehydration zone to guide the material tray into the dehydration zone. The upper limit frame 51 and the lower limit frame 52 are arranged parallel to the rotation axis 541, which is driven to rotate by a driving device.

[0048] Furthermore, such as Figure 1As shown, the tray container outer surface cleaning device 4 and the rotary dewatering device 5 are both mounted on a frame. The frame also includes an inlet tray conveying track 1, an outlet tray conveying track 6, and a control console 7. The outlet end of the inlet tray conveying track 1 is connected to the feed inlet of the clamping area. A horizontally arranged inlet tray cylinder 2 is also installed on the frame at the outlet end of the inlet tray conveying track 1. The inlet tray cylinder 2 is used to push the material tray 9 on the inlet tray conveying track 1 into the clamping area. The outlet of the dewatering area of ​​the rotary dewatering device 5 is connected to the inlet of the outlet tray conveying track 6. A horizontally arranged outlet tray cylinder 3 is provided on the frame on the side opposite to the discharge port of the clamping area. The outlet tray cylinder 3 is used to push the material tray 9 in the clamping area into the dewatering area. The control console 7 is equipped with a controller, which is connected to the inlet tray cylinder 2, the outlet tray cylinder 3, the tray container outer surface cleaning device 4, and the rotary dewatering device 5.

[0049] The working principle of an integrated drying machine is as follows:

[0050] The material trays 9 filled with containers to be cleaned are placed sequentially at the inlet of the tray conveying track 1. The tray conveying track 1 transports the material trays 9 to the inlet of the tray container outer surface cleaning device 4. The tray cylinder 2 is activated to push the material trays 9 from the inlet into the clamping area of ​​the tray clamping device 43. The tray container outer surface cleaning device 4 is activated, and the lifting cylinder 44 drives the material trays 9 to be completely submerged in the water of the heated cleaning tank 41. The water agitation mechanism 42 beats the water up and down to make the water flow rapidly, thereby cleaning the containers 8 to be cleaned.

[0051] After the set cleaning time is reached, the lifting cylinder 44 drives the material tray 9 to rise above the water surface. Then, the discharge cylinder 3 pushes the material tray 9 out of the material tray clamping device 43 and into the dehydration zone of the rotary dehydration device 5. Next, the rotating shaft 541 of the rotary dehydration device 5 rotates at high speed under the drive mechanism, using centrifugal force to spin off the water on the surface of the container 8 to be cleaned. After the spin-drying is completed, the discharge cylinder 3 acts again to push another cleaned material tray 9 from the outer surface cleaning device 4 of the tray container into the dehydration zone, thereby squeezing out the material tray 9 that was originally in the dehydration zone and completed dehydration. This allows the dehydrated material tray 9 to enter the discharge conveyor track 6 and be sent to the designated position through the discharge conveyor track 6, thus completing the entire cleaning and drying process.

[0052] like Figures 8 to 11 The following are three implementation methods of the material tray 9 of this device:

[0053] Example 1:

[0054] like Figure 8As shown, the material tray 9 is horizontally arranged with its opening facing upwards. The bottom plate and side walls of the material tray 9 are covered with permeable holes to minimize water residue during washing and spin-drying. The material tray 9 is filled with containers 8 to be cleaned. The containers 8 are arranged with their openings facing upwards and their height is greater than the depth of the material tray 9. When the height of the containers to be cleaned is less than the depth of the material tray, a permeable plate is placed on one side of the opening of the containers to be cleaned, so that the overall height of the permeable plate and the containers to be cleaned is greater than the depth of the material tray. The permeable plate is also covered with permeable holes, which are round or oblong holes.

[0055] Example 2:

[0056] like Figure 9 , 10 The difference between the material tray 9 in this embodiment and that in embodiment 1 is that an opening on one side wall of the material tray 9 forms an inlet / outlet 93 that facilitates the simultaneous insertion of multiple containers 8 to be cleaned into the material tray 9. A movable baffle 92, matching the size of the inlet / outlet, is movably fitted onto the inlet / outlet of the material tray 9. Connecting plates are fixed to both sides of the movable baffle 92, which is hinged to the side walls on both sides of the inlet / outlet via the connecting plates. The connecting plates are hinged to the side walls using a freely adjustable damping pivot. The bottom plate of the material tray 9 protrudes outward from the side wall near the inlet / outlet to form a retaining edge. In the washing and spin-drying state, the movable baffle 92 is positioned at the inlet / outlet of the material tray 9 to close the inlet / outlet. At this time, the bottom of the movable baffle 92 is supported on the baffle. In the feeding state, the movable baffle 92 flips upward to open the inlet / outlet of the material tray 9, facilitating the entry of the containers 8 to be cleaned.

[0057] Example 3:

[0058] like Figure 11 The difference between the material tray 9 in this embodiment and that in embodiment 2 is that the material tray 9 has slots on its inlet and outlet, and the movable baffle is replaced by a plug plate 96. The plug plate 96 is matched with the size of the inlet and outlet, and the inlet and outlet of the material tray 9 are closed by inserting the plug plate 96 into the slot.

[0059] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
