Description

Technical Field

[0001] The present application relates to the technical field of cup cover production, and in particular to a collecting device for cup covers. Background Art

[0002] With the continuous development of the catering industry and the gradual improvement of environmental requirements, paper cups have gradually replaced plastic cups and been introduced into the catering industry. In order to prevent dirt in the environment from falling into paper cups, people often equip paper cups with some cup lids. In production, the cup lids are formed, punched and cut, and the cup lid forming device is the processing equipment for the cup lids.

[0003] Publication number CN209633738U discloses a cup lid forming device, including a reeling device and a frame, on which a pretreatment device, a punching device, and a blanking device are arranged in sequence starting from the reeling device. A material receiving device is provided at the upper end of the blanking device. The blanking device includes a blanking upper die and a blanking lower die, and a conveying device is provided on the blanking lower die.

[0004] In the above technical solution, since the cup lids fall freely from the conveying device into the collection box, the cup lids are scattered during the falling process and need to be sorted by personnel in the subsequent packaging process, which is relatively inefficient. Utility Model Content

[0005] In order to collect and sort the processed cup lids, the present application provides a cup lid collection device, which adopts the following technical solution:

[0006] A collection device for cup lids, comprising a bracket, a first conveyor belt and a collection assembly, wherein the first conveyor belt is obliquely installed on the bracket, and an output end of the first conveyor belt is located at a lower side;

[0007] The collecting assembly includes a collecting barrel and a transition plate. The collecting barrel is vertically mounted on the bracket and is located on one side of the output end of the first conveyor belt. The collecting barrel is a hollow barrel with openings at both ends and an inner diameter consistent with that of the cup cover. The transition plate is installed between the collecting barrel and the first conveyor belt and is used to introduce the cup cover on the first conveyor belt into the upper opening of the collecting barrel.

[0008] By adopting the above technical solution, the cup lids fall from the cup lid forming machine onto the first conveyor belt, the first conveyor belt transports the cup lids to the transition plate, and finally the cup lids slide from the transition plate into the collecting bucket. Since the inner diameter of the collecting bucket is consistent with the diameter of the cup lids, the cup lids fall vertically from the collecting bucket. Since the falling trajectory of the cup lids is fixed, personnel only need to collect the fallen cup lids directly under the collecting bucket, thereby improving personnel collection efficiency.

[0009] Optionally, the transition plate is a hollow plate, a plurality of air outlet holes connected to the inner cavity of the transition plate are opened on the upper surface of the transition plate, an air inlet pipe connected to an air pump is installed on the transition plate, and the air inlet pipe is connected to the inner cavity of the transition plate.

[0010] By adopting the above technical solution, the air pump pumps air into the transition plate cavity, and then the gas is ejected from the air outlet, reducing the friction between the cup cover and the transition plate, thereby preventing the cup cover from staying on the transition plate.

[0011] Optionally, a switch assembly is also included, which includes a sealing plate and a first driving member. The sealing plate is horizontally arranged and slides on the collecting barrel in a direction perpendicular to the axis of the collecting barrel, and the sealing plate is used to seal the inner cavity of the collecting barrel; the first driving member is used to drive the sealing plate to slide on the collecting barrel.

[0012] By adopting the above technical solution, personnel control the blocking plate through the first driving member to block the inner cavity of the collection barrel, so that the cup lids that fall into the collection barrel are gradually stacked, and then the stacked cup lids are dropped at one time, thereby improving the packaging efficiency of personnel.

[0013] Optionally, a pressure sensor is embedded on the upper surface of the sealing plate.

[0014] By adopting the above technical solution, when the cup lids in the collection barrel are stacked to a certain extent, the pressure sensor provides data feedback to the controller, and the controller controls the first driving member to drive the blocking plate to open the inner cavity of the collection barrel.

[0015] Optionally, a strip-shaped air leakage hole is vertically opened on the upper side wall of the collection barrel.

[0016] By adopting the above technical solution, when the cup covers fall from the collection barrel, in order to avoid the increase of air pressure between the two cup covers, which causes the cup covers to fail to fall or slow down the falling speed, the pressure between the two cup covers is normalized through the air leakage hole.

[0017] Optionally, an air flow nozzle is provided just above the upper opening of the collection barrel.

[0018] By adopting the above technical solution, when the cup lids fall, the air flow nozzles are used to impact the cup lids in the collection barrel at intervals, thereby accelerating the falling speed of the cup lids and increasing the compactness of the stacking.

[0019] Optionally, it also includes a transport component, which includes a second conveyor belt and a protective plate, the second conveyor belt is located below the collecting bucket, and the protective plate is vertically arranged on the belt surface of the second conveyor belt. During the operation of the second conveyor belt, the protective plate can move with the second conveyor belt to below the collecting bucket, and the cup lid in the collecting bucket slides down along the protective plate on the side close to the input end of the second conveyor belt.

[0020] By adopting the above technical solution, the stacked cup lids slide along the protective plate to the second conveyor belt. The stacked cup lids are guided by the protective plate during the falling process to prevent scattering. The second conveyor belt directly transports the stacked cup lids to the packaging location.

[0021] Optionally, a flexible protective rope is connected to one side of the side wall of the collecting bucket away from the feeding end of the second conveyor belt, one end of the protective rope is connected to the collecting bucket, and the other end hangs down above the second conveyor belt.

[0022] By adopting the above technical solution, the stacked paper cups in the collection barrel are guided by the protective rope and the protective plate and fall smoothly onto the second conveyor belt, and the protective rope will not affect the normal use of the protective plate.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] The embodiment of the present application discloses a collecting device for a cup lid.

[0028] Reference Figure 1 and Figure 2A cup lid collecting device comprises a bracket 1, a first conveyor belt 2 and a collecting assembly 3. The first conveyor belt 2 is obliquely arranged below the discharge end of the cup lid processing equipment through the bracket 1, and the higher end is the input end. The collecting assembly 3 is used to collect and stack the cup lids on the first conveyor belt 2 to facilitate subsequent personnel to pack the cup lids.

[0029] Reference Figure 1 and Figure 2 The collecting assembly 3 includes a collecting barrel 31 and a transition plate 32. In the present application, the collecting barrel 31 is a hollow barrel with an inner diameter consistent with the diameter of the cup cover and openings at both ends. The collecting barrel 31 is vertically installed through the bracket 1 below the output end of the first conveyor belt 2 away from the input end. One end of the transition plate 32 overlaps the belt surface of the output end of the first conveyor belt 2, and the other end is fixed to the side wall of the collecting barrel 31, and the upper surface of the transition plate 32 is flush with the upper belt surface of the first conveyor belt 2. A feeding port 311 with a width consistent with the diameter of the cup cover is opened on the side wall of the collecting barrel 31, and the bottom end of the feeding port 311 is flush with the upper surface of the transition plate 32, so that the cup cover on the first conveyor belt 2 enters the collecting barrel 31 through the transition plate 32, and the cup cover slides horizontally and vertically in the collecting barrel 31. Personnel only need to collect them at the opening at the lower end of the collecting barrel 31.

[0030] Reference Figure 1 and Figure 2 In order to prevent the cup cover from staying on the transition plate 32, the transition plate 32 in the present application is a hollow plate, and a plurality of air outlet holes 321 connected to the inner cavity of the transition plate 32 are provided on the upper surface of the transition plate 32. An air inlet pipe 322 is installed at the bottom of the transition plate 32. One end of the air inlet pipe 322 is connected to the inner cavity of the transition plate 32, and the other end is connected to an air pump. The air pump pumps external gas into the inner cavity of the transition plate 32 through the air inlet pipe 322, and then outputs it from the air outlet hole 321, so as to reduce the friction between the cup cover and the transition plate 32 and prevent the cup cover from staying on the transition plate 32.

[0031] Reference Figure 1 and Figure 2 At the same time, in order to guide and limit the cup covers on the first conveyor belt 2 and the transition plate 32, two limit plates 33 are provided on the transition plate 32 on both sides of the conveying direction of the first conveyor belt 2. The two limit plates 33 are symmetrically arranged, and in the conveying direction of the first conveyor belt 2, the distance between the two limit plates 33 gradually decreases until it is consistent with the diameter of the cup covers.

[0032] Reference Figure 1 and Figure 2In order to allow personnel to collect the cup lids in the collection barrel 31 after they are stacked to a certain extent, the material collection mechanism also includes a switch assembly 4, which is installed on the collection barrel 31 and is located below the feed port 311. The switch assembly 4 includes a blocking plate 41 and a first driving member 42. The blocking plate 41 is inserted into the collection barrel 31 on the collection barrel 31 along a direction perpendicular to the axis of the collection barrel 31. In order to facilitate the insertion of the blocking plate 41, a slot 312 is provided on the side wall of the collection barrel 31 along a direction perpendicular to the axis of the collection barrel 31. The blocking plate 41 slides in the slot 312. In the present application, the first driving member 42 is a cylinder. The first driving member 42 body is fixed on the collection barrel 31. The output shaft of the first driving member 42 is fixedly connected to the blocking plate 41 through a connecting rod, thereby driving the blocking plate 41 to be inserted into the collection barrel 31. When the blocking plate 41 is inserted into the collection barrel 31, the inner cavity of the collection barrel 31 cannot be connected up and down.

[0033] Reference Figure 1 and Figure 2 In order to count the cup lids in the collection barrel 31, a pressure sensor 43 is embedded on the upper surface of the blocking plate 41. When the cup lids in the collection barrel 31 are stacked to a certain extent, the pressure sensor 43 feeds back data to the controller, and the controller controls the first driving member 42 to work and release the stacked cup lids in the collection barrel 31 for collection by personnel.

[0034] Reference Figure 1 In order to prevent the air pressure between the two cup covers from increasing as the cup covers slide down in the collection barrel 31, causing the cup covers to fall too slowly or fail to fall, a strip-shaped air leakage hole 313 is vertically opened on the side wall of the collection barrel 31.

[0035] Reference Figure 1 and Figure 2 In order to increase the falling speed of the cup lids and the compactness of the stacking, an airflow nozzle 34 is arranged just above the opening of the upper end of the collecting barrel 31. The airflow nozzle 34 is connected to an air pump. The air pump intermittently sprays airflow to the cup lids that fall into the collecting barrel 31, thereby increasing the falling speed of the cup lids and increasing the compactness of the stacking between two cup lids.

[0036] Reference Figure 1 and Figure 2In order to facilitate personnel to collect the stacked cup lids, the material receiving mechanism also includes a conveying assembly 5, which includes a second conveyor belt 51 and a plurality of protective plates 52. The second conveyor belt 51 is horizontally arranged below the collecting bucket 31. In the present application, the protective plate 52 is an arc-shaped plate with an inner diameter consistent with the inner diameter of the collecting channel. The protective plate 52 is vertically arranged on the belt surface of the second conveyor belt 51, and the arc opening faces the conveying direction of the second conveyor belt 51. The protective plate 52 can move with the second conveyor belt 51 to a position coaxial with the collecting channel and directly below the collecting bucket 31. A plurality of protective plates 52 are distributed along the circumference direction of the second conveyor belt 51. When the protective plate 52 moves to be coaxial with the collecting bucket 31, the second conveyor belt 51 stops, and waits for the first driving member 42 to open the blocking plate 41. The stacked cup lids fall onto the second conveyor belt 51 along the protective plate 52, and the second conveyor belt 51 starts to work until the next protective plate 52 is coaxial with the collecting bucket 31.

[0037] Reference Figure 1 In order to further protect the stacked items in the collecting bucket 31 from falling into the second conveying process, a flexible protective rope 35 is bonded to the outer wall of the collecting bucket 31. One end of the protective rope 35 is bonded to the collecting bucket 31, and the other end naturally hangs down to the upper surface of the second conveyor belt 51. In this application, the protective rope 35 is made of rubber.

[0038] The implementation principle of a collection device for cup lids in an embodiment of the present application is as follows: the cup lids formed from the cup lid processing equipment first fall onto the first conveyor belt 2, enter the transition plate 32 along the first conveyor belt 2, enter the collecting barrel 31 from the feed port 311 of the collecting barrel 31 after being sorted by two limit plates 33, and then fall onto the blocking plate 41 for stacking. When a certain number of cup lids in the collecting barrel 31 are stacked, the driving member drives the blocking plate 41 to slide, and the cup lids slide from the collecting barrel 31 along the protective plate 52 and the protective rope 35 to the second conveyor belt 51, and the second conveyor belt 51 transports the stacked cup lids to the personnel packaging area.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
