Description

Technical Field

[0001] This utility model belongs to the field of product testing technology, specifically relating to a material mixing device and a molding product testing equipment. Background Technology

[0002] Pre-molded products (such as paper bowls, paper cups, and paper buckets with bottom seals) are popular due to their convenience, hygiene, affordability, and high quality. Their use is no longer limited to the catering industry; it is also rapidly increasing in ordinary households and business offices.

[0003] Currently, in order to match the production speed of the molding equipment with the inspection speed of the molding inspection equipment, a two-in-one Y-type cup-collecting connector is usually used in the molding inspection equipment to collect the molded products produced by the two molding equipment. The upper part of the two-in-one Y-type cup-collecting connector has two separate receiving channels, and the lower part is a merging channel. The two receiving channels are inclined so that the lower ends are guided to the upper end of the merging channel. The inclination angle of the two receiving channels is set to be small, which results in a relatively large height dimension, making the whole machine relatively tall. Utility Model Content

[0010] In one embodiment of the present invention, the material collection channel includes a cage assembly and a connecting seat assembly, the connecting seat assembly being disposed on the cage assembly, and the material blocking mechanism being installed on the connecting seat assembly.

[0011] In one embodiment of this utility model, the upper opening of the material hopper is waist-shaped, the lower opening of the material hopper is circular, and the inner cavity of the material hopper transitions from the waist-shaped opening to the circular opening in the direction from top to bottom.

[0012] To achieve the above objectives, a second aspect of this utility model provides a molding product testing device, which includes a frame, a material distribution device, a rotary station device, a testing device, a unloading device, and a material combining device as described above. The material combining device, the material distribution device, and the rotary station device are arranged sequentially from top to bottom on the frame. The outlet of the material combining module is connected to the inlet of the material distribution device. The rotary station device is connected to a rotational power component. The rotary station device is provided with a loading station, a testing station, and an unloading station at intervals along the circumference. The testing device is set corresponding to the testing station, the material distribution device is set corresponding to the loading station, and the unloading device is set corresponding to the unloading station.

[0013] In one embodiment of this utility model, a number of mold seats for receiving molded products are arranged sequentially along the circumference of the rotary station device. The mold seats form a mold cavity with air holes. The molded product testing equipment also includes an air path control device. The air path control device includes a control valve seat and a number of air path components. The control valve seat has a positive pressure air source inlet, a negative pressure air source inlet and a number of solenoid valves. The air inlet of each solenoid valve can be switched between being connected to the positive pressure air source inlet and the negative pressure air source inlet. The air path components are respectively connected to the air outlet of the solenoid valve and the mold cavity.

[0014] In one embodiment of this utility model, the air circuit assembly includes an air circuit rotary joint, a first air pipe, and a second air pipe. The air circuit rotary joint is located at the center of the rotary station device, and the fixed part of the air circuit rotary joint is mounted on the frame.

[0018] Through the above technical solution, the material mixing device provided by the present utility model embodiment has the following beneficial effects:

[0019] When using the above-mentioned material combining device, since there is a material combining cylinder for the material combining module below the two material collecting modules, the opening diameter of the material combining hopper gradually decreases from top to bottom. The upper opening of the material combining hopper is respectively connected to the material collecting channels of the two material collecting modules. A guide is installed inside the material combining hopper, and the upper end of the guide is rotatably installed in the upper opening of the material combining hopper. The guide is located between the lower extension directions of the two material collecting channels, so that the space of the material combining hopper on both sides of the guide can be used for forming products (paper cups, paper bowls, paper buckets, and other paper products) in different material collecting channels. For material feeding, molded products from different collection channels can converge at the lower end of the guide and exit from the lower opening of the hopper. This allows for combined feeding from two molding machines. Furthermore, replacing the two separate receiving channels in existing technology with a hopper expands the feeding space on the feeding side by allowing the guide to deflect to the other side when feeding from one side. Sufficient feeding space on the feeding side allows the hopper to be tilted at a larger angle than the receiving channels, thus reducing the hopper's height and overall machine size. In addition, the guide has a single-sided flow function to prevent congestion caused by material coming from both sides.

[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0034] The following description, with reference to the accompanying drawings, describes the material mixing device and the molded product testing equipment of this utility model.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, this utility model provides a material mixing device 100, wherein the material mixing device 100 includes:

[0036] There are two material collection modules 110, which are arranged in parallel. The material collection modules 110 form a material collection channel 120 for the molded product 900 to fall.

[0037] The material mixing module 130 includes a material mixing hopper 131 located at the lower end of the two material collecting modules 110. The opening diameter of the material mixing hopper 131 gradually decreases from top to bottom. The upper opening of the material mixing hopper 131 communicates with the material collecting channels 120 of the two material collecting modules 110. A guide member 133 is installed inside the material mixing hopper 131. The upper end of the guide member 133 is rotatably installed in the upper opening of the material mixing hopper 131. The guide member 133 is located between the lower extension directions of the two material collecting channels 120. The lower opening of the material mixing hopper 131 is the discharge port of the material mixing module 130.

[0038] When using the above-mentioned material mixing device 100, since the material mixing cylinder 132 of the material mixing module 130 is provided below the two material collecting modules 110, the opening diameter of the material mixing hopper 131 gradually decreases from top to bottom. The upper opening of the material mixing hopper 131 communicates with the material collecting channels 120 of the two material collecting modules 110 respectively. A guide 133 is installed inside the material mixing hopper 131. The upper end of the guide 133 is rotatably installed in the upper opening of the material mixing hopper 131, and the guide 133 is located between the lower extension directions of the two material collecting channels 120. Thus, the space of the material mixing hopper 131 on both sides of the guide 133 can accommodate the molded products 900 (paper cups, etc.) in different material collecting channels 120. Paper products (such as paper bowls and paper buckets) are fed into the machine. The formed products 900 in different collecting channels 120 can converge at the lower end of the guide 133 and exit from the lower opening of the hopper 131. This allows for combined feeding from two forming machines of the formed products 900. The hopper 131 replaces the two separate receiving channels in the prior art. Since the guide 133 can deflect to the other side when feeding from one side, the feeding side space is expanded. With sufficient space on the feeding side, the tilt angle of the hopper 131 can be set larger than that of the receiving channels, thus reducing the height of the hopper 131 and lowering the overall machine size. Furthermore, the guide 133 also has a single-sided guiding function, preventing congestion caused by feeding from both sides.

[0039] Specifically, the guide 133 can be configured as a guide plate. The upper end of the guide 133 can be rotatably mounted inside the material collection hopper 131 via a rotating shaft. The axis of the rotating shaft extends between the material collection channels 120 of the two material collection modules 110. The lower end of the guide 133 is positioned higher than the lower opening of the material collection hopper 131 to facilitate material discharge from the lower opening of the material collection hopper 131. Furthermore, when neither of the two material collection modules 110 is feeding material, the guide 133 remains in a naturally drooping state. When one of the material collection modules 110 is feeding material, the molded product 900 will enter the space of the corresponding side of the material collection hopper 131, and the guide 133 will rotate to the other side under the lateral pressure of the molded product 900 to ensure that the molded product 900 can be smoothly discharged from the lower opening of the material collection hopper 131. At the same time, the guide 133 can turn to close the space of the other side of the material collection hopper 131, so that even if the other material collection module 110 is feeding material, it will not cause congestion.

[0040] More specifically, the lower opening of the material hopper 131 is the discharge port of the material hopper module 130. The lower opening of the material hopper 131 is connected to the material hopper cylinder 132. The material hopper 131 and the material hopper cylinder 132 are arranged sequentially from top to bottom, and the upper opening of the material hopper cylinder 132 is connected to the lower opening of the material hopper 131 to continue to guide the molded product 900 downward, specifically to the material distribution device 300.

[0041] See Figure 1 , Figure 3 and Figure 5 In one embodiment of this utility model, the material collection module 110 is provided with a material blocking mechanism 111, which is disposed in the material collection channel 120. By adding the material blocking mechanism 111, when one material collection channel 120 is discharging material into the material collection module 130, the material blocking mechanism 111 on the other material collection channel 120 can block the material flow, further ensuring that congestion is avoided. Specifically, the material blocking mechanism 111 can switch between blocking and opening the corresponding material collection channel 120. When one material collection channel 120 is discharging material, the corresponding material blocking mechanism 111 is in an open state, while the material blocking mechanism 111 on the other material collection channel 120 can be in a blocking state.

[0042] In one embodiment of this utility model, two sets of material blocking mechanisms 111 are arranged vertically on the same material collection module 110. By arranging two sets of material blocking mechanisms 111 vertically on the same material collection module 110, it is possible to feed incoming materials in batches. The rhythmic feeding helps to maintain the continuity of the production rhythm and improve production efficiency. Specifically, when materials arrive at the same material collection module 110, the upper baffle mechanism 111 can be kept open and the lower baffle mechanism 111 can be kept closed, so that the incoming material falls onto the lower baffle mechanism 111 first. After a preset time interval or a preset number of materials are fed, the upper baffle mechanism 111 is kept closed and the lower baffle mechanism 111 is kept open, so that while the lower baffle mechanism 111 is feeding materials, the upper baffle mechanism 111 can receive new materials. After a preset time interval or a preset number of materials are fed, the upper baffle mechanism 111 is kept open and the lower baffle mechanism 111 is kept closed, so that the materials falling from the upper baffle mechanism 111 fall onto the lower baffle mechanism 111.

[0043] In one embodiment of this utility model, a material counting sensor is also provided on the material collection channel 120, and the material counting sensor is located above the material blocking mechanism 111. By adding the material counting sensor, when the material blocking mechanism 111 on the lower side is in a blocking state, the number of molded products 900 falling onto the material blocking mechanism 111 on the lower side can be counted, so that when the number of molded products 900 on the material blocking mechanism 111 accumulates to a preset feeding quantity, the material supply is interrupted or the feeding is switched to another material collection module 110.

[0044] Furthermore, when two sets of blocking mechanisms 111 are arranged vertically on the same material collection module 110, the number of dropping counting sensors on the same material collection module 110 can also be set to two. One dropping counting sensor is used to count the number of molded products 900 falling onto the lower blocking mechanism 111. When the number of molded products 900 on the lower blocking mechanism 111 reaches the preset dropping quantity, the upper blocking mechanism 111 can be controlled to remain in a blocking state, and the lower blocking mechanism 111 can be controlled to remain in an open state. The other dropping counting sensor is used to count the number of molded products 900 falling onto the upper blocking mechanism 111. When the number of molded products 900 on the upper blocking mechanism 111 reaches the preset dropping quantity, the upper blocking mechanism 111 can be controlled to remain in an open state, and the lower blocking mechanism 111 can be controlled to remain in a blocking state, so that the dropping material on the upper blocking mechanism 111 falls onto the lower blocking mechanism 111.

[0045] In one embodiment of this utility model, each group of material blocking mechanisms 111 contains at least two material blocking mechanisms 111. These at least two material blocking mechanisms 111 are arranged equidistantly along the periphery of the material collection channel 120. Each material blocking mechanism 111 includes a telescopic drive member 113 and a material blocking member 114. The drive end of the telescopic drive member 113 faces the inner side of the material collection channel 120 and is connected to the material blocking member 114. By setting the number of material blocking mechanisms 111 in each group of material blocking mechanisms 111 to at least two, the telescopic distance of the telescopic drive member 113 can be reduced. Preferably, each set of material blocking mechanisms 111 has two material blocking mechanisms 111, which are arranged facing each other. When it is necessary to block the material collection channel 120, the telescopic drive members 113 of the two material blocking mechanisms 111 are controlled to extend, so as to drive the corresponding material blocking member 114 to move closer to each other and to carry the unloaded molded product 900. The material blocking member 114 includes a vertical plate portion connected to the telescopic end of the telescopic drive member 113 and a horizontal plate portion that bends inward from the lower end of the vertical plate portion. The horizontal plate portion can carry the unloaded molded product 900. At least two horizontal plate portions in each set of material blocking mechanisms 111 extend and retract synchronously, which can better ensure the stability of the posture of the molded product 900.

[0046] In one embodiment of this utility model, the material collection channel 120 includes a cage assembly and a connecting seat assembly. The connecting seat assembly is disposed on the cage assembly, and the material blocking mechanism 111 is installed on the connecting seat assembly. The cage assembly includes a first cage 122 and a second cage 124. The connecting seat assembly includes a first connecting seat 121 and a second connecting seat 123. The first connecting seat 121, the first cage 122, the second connecting seat 123, the second cage 124, and the inlet section 125 are arranged sequentially from bottom to top. The first cage 122 is connected to the first connecting seat 121, and the first connecting seat 121 is disposed at the lower end of the first cage 122. The material blocking mechanism 111 is disposed on the first connecting seat 121. Similarly, the second cage 124 is connected to the second connecting seat 123, and the second connecting seat 123 is disposed at the lower end of the second cage 124. The material blocking mechanism 111 is disposed on the second connecting seat 123. It should be noted that the cage assembly is hollowed out, allowing a clear view of the material feeding process, and the connecting seat assembly facilitates the installation of the material-blocking mechanism 111. Both the first cage 122 and the second cage 124 include a first upright and a second upright, respectively erected on opposite sides of the connecting seat assembly, with the material-blocking mechanism 111 located between the corresponding first and second uprights. More specifically, the second cage 124 has the same structure as the first cage 122; the first connecting seat 121 accommodates the lower material-blocking mechanism 111, and the second connecting seat 123 accommodates the upper material-blocking mechanism 111.

[0047] In one embodiment of this utility model, the upper opening of the material hopper 131 is waist-shaped to facilitate communication with the two parallel material collection channels 120. The lower opening of the material hopper 131 is circular to facilitate merging and feeding, so as to communicate with the material collection cylinder 132. The inner cavity of the material hopper 131 transitions from a waist-shaped opening to a circular opening in the direction from top to bottom.

[0048] In addition, such as Figure 1 and Figure 2 As shown, this utility model also provides a molding product testing device, which includes a frame 200, a material distribution device 300, a rotary station device 400, a testing device 500, a unloading device 600, and a material combining device 100 as described above. The material combining device 100, the material distribution device 300, and the rotary station device 400 are arranged sequentially from top to bottom on the frame 200. The outlet of the material combining module 130 is connected to the inlet of the material distribution device 300. The rotary station device 400 is connected to a rotating power component and can be arranged to rotate horizontally. The rotary station device 400 is provided with a loading station, a testing station, and an unloading station at intervals along the circumference. The testing device 500 is set corresponding to the testing station, the material distribution device 300 is set corresponding to the loading station, and the unloading device 600 is set corresponding to the unloading station.

[0049] Furthermore, after the material from the two molding machines 900 is fed together by the material combining device 100, it can enter the material separating device 300 so that the material separating device 300 can separate the stacked molding products 900 one by one from bottom to top. After separation, the individual molding products 900 can fall onto the rotating station device 400 at the loading station, and then be rotated by the rotating station device 400 to the inspection station and the unloading station. At the inspection station, the appearance inspection is completed by the inspection device 500, and at the unloading station, the unloading device 600 completes the unloading of the molding products 900, thereby realizing the fully automated inspection of the molding products 900.

[0050] See Figure 1 , Figure 2 and Figure 7 , Figure 9 In one embodiment of this utility model, a plurality of mold bases 700 for receiving molded products 900 are arranged sequentially along the circumference of the rotary station device 400. The mold bases 700 form a mold cavity 701 with air holes. The molded product testing equipment also includes an air path control device 800. The air path control device 800 includes a control valve seat 810 and a plurality of air path components. The control valve seat 810 has a positive pressure air source inlet 811, a negative pressure air source inlet 812 and a plurality of solenoid valves. The air inlet of each solenoid valve can be switched between being connected to the positive pressure air source inlet 811 and the negative pressure air source inlet 812. The air path components are respectively connected to the air outlet of the solenoid valve and the mold cavity 701. After the rotary station device 400 rotates to the loading position of one of the mold bases 700, the molded product 900 can fall onto the mold base 700. The solenoid valve corresponding to the mold base 700 can be controlled to switch its air inlet to connect with the negative pressure air source inlet 812, thereby vacuum-suctioning the mold cavity 701. This allows the molded product 900 to adhere to the mold base 700, ensuring its stability. Furthermore, when the mold base 700 rotates to the unloading position driven by the rotary station device 400, the solenoid valve corresponding to the mold base 700 can be controlled to switch its air inlet to connect with the positive pressure air source inlet 811, blowing the molded product 900 away from the mold base 700, thus facilitating the unloading of the molded product 900.

[0051] Specifically, the number of mold bases 700 can be consistent with the number of stations of the rotary station device 400 to ensure the continuity of feeding, inspection and unloading. The feeding of the molded product 900 on the mold base 700 is inverted feeding. The mold base 700 can be set in the shape of the molded product 900. The outer side of the mold base 700 can be provided with rubber or nylon parts to facilitate the adsorption of the molded product 900. Air holes can be provided at the top of the mold base 700, and the number of air holes can be multiple.

[0052] See Figure 7 and Figure 8 In one embodiment of this utility model, the air circuit assembly includes an air circuit rotary joint 820, a first air pipe 830, and a second air pipe 840. The air circuit rotary joint 820 is located at the center of the rotary station device 400, and the fixing part 821 of the air circuit rotary joint 820 is mounted on the frame 200, while the rotating part 822 of the air circuit rotary joint 820 is mounted on the rotary station device 400. The first connector 823 on the fixing part 821 is connected to the corresponding air outlet of the solenoid valve through the first air pipe 830, and the second connector 824 on the rotating part 822 is connected to the corresponding mold cavity 701 through the second air pipe 840. By adding the air circuit rotary joint 820, the air pipes will not become entangled when the rotary station device 400 rotates, ensuring the orderly arrangement of the air pipes. It should be noted that the air circuit rotary joint 820 is an existing standard component and will not be described in detail here.

[0053] like Figure 2 As shown, in one embodiment of this utility model, the feeding device 600 includes a feeding tube 601 disposed on the upper side of the feeding station, so that the molded product 900 on the feeding station can be fed by blowing upward into the feeding tube 601. The feeding tube 601 facilitates feeding guidance and long-distance transmission. Furthermore, when the feeding tube 601 is long, a vacuum suction device can be provided at the other end of the feeding tube 601 away from the feeding station to ensure smooth feeding.

[0054] Please see again Figure 1 and Figure 2 In one embodiment of this utility model, there are five inspection stations, each equipped with an inspection device 500. One inspection device 500 at one station is configured to perform visual inspection of the bottom of the molded product 900, while the remaining four inspection devices 500 at the other stations are configured to perform visual inspection of the periphery of the molded product 900 from different directions. This decomposes the inspection action from one station into five stations, allowing each station to inspect only one direction. This enables comprehensive inspection of the appearance of the molded product 900, ensuring the reliability of the appearance inspection, and also avoids mutual interference during visual inspection, greatly improving the accuracy of visual inspection. Specifically, the order of the five inspection stations can be changed, as long as the visual inspection function is completed. Light sources can also be provided at the five inspection stations; the number and position of the light sources are not limited, as long as they can illuminate the molded product 900 from all directions. Preferably, each inspection device 500 is equipped with a corresponding light source.

[0055] In one embodiment of this utility model, the unloading station includes a qualified product unloading station and a non-qualified product unloading station, each equipped with a corresponding unloading device 600. This allows for the differentiation of whether the molded product 900 is qualified during the unloading process by the rotating station device 400, eliminating the need for subsequent sorting. The order of the qualified product unloading station and the non-qualified product unloading station can be interchanged. When the detection device 500 detects that the appearance of the molded product 900 is qualified, the corresponding unloading device 600 can unload the molded product 900 when the molded product 900 rotates to the qualified product unloading station. Conversely, when the detection device 500 detects that the appearance of the molded product 900 is unqualified, the corresponding unloading device 600 can unload the molded product 900 when the molded product 900 rotates to the non-qualified product unloading station.

[0056] Specifically, the rotary station device 400 includes a turntable connected to a rotary power component, preferably a motor, which can be a DD motor (Direct Drive Motor). The turntable is rotatably mounted on the frame 200. The DD motor drives the turntable to start and stop intermittently, with each rotation being 1 / 8 of a turn of the turntable. The turntable can have eight stations, which can be, in order, a loading station, five inspection stations, a qualified product unloading station, and a non-qualified product unloading station. The turntable can also have eight mold bases 700 arranged circumferentially at intervals. Correspondingly, the control valve seat 810 can have eight solenoid valves, and the number of air circuit components can also be set to eight, so as to connect the eight solenoid valves and the mold cavities 701 of the eight mold bases 700 one by one.

Each spiral distribution shaft 305 has a spiral groove for the edge of the molded product 900 to be clamped. The upper end of each spiral distribution shaft 305 is fitted with a driven wheel 303. The rotary drive 301 is arranged on the frame 200 and the output end is provided with a drive wheel 302. The timing belt 304 is wound around the drive wheel 302 and the driven wheel 303. Each spiral distribution shaft 305 is also provided with an air nozzle 306 on its upper side. Specifically, the material distribution device 300 also includes a material distribution cylinder connected to the material collection cylinder 132. The material distribution cylinder extends into the space enclosed by the driven wheel 303. After the protruding edge of the lower end of the inverted molded product 900 enters the spiral groove through the upper opening of the spiral groove, the rotary drive 301 can be controlled to rotate, thereby driving at least two spiral material distribution shafts 305 to rotate synchronously, and thus driving the molded product 900 to descend and separate. In addition, in order to make the molded product 900 fall onto the mold base 700 of the loading station faster and more accurately, an air blowing nozzle 306 can be added to each spiral material distribution shaft 305 to accelerate the falling speed of the molded product 900 by blowing air through the air blowing nozzle 306.

[0058] Preferably, the number of spiral distributing shafts 305 can be four, that is, four driven wheels 303 are correspondingly provided. At the same time, the distributing device 300 also includes a tensioning wheel for the synchronous belt 304 to be wound. The tensioning wheel can be located between the driving wheel 302 and the driven wheel 303, and the spiral distributing shafts 305 and the driven wheels 303 can be directly connected, or they can be connected by a gear set for transmission.
