Description

Technical Field

[0001] The invention relates to the technical field of laser detection, in particular to a laser detection device for detecting the length of an ice sand machine handle. Background Art

[0002] Smoothie machines, also known as smoothie blenders or smoothie makers, are commercial cold drink machines primarily used in beverage shops, cafes, and other settings. They utilize 3D vortex cold brew technology to directly transform liquid into smoothie, eliminating the need for pre-made ice. Utilizing an industrial-grade motor and six stainless steel blades, they support dual hot and cold operation with two-stage speed adjustment and are available with both tempered glass and heat-resistant plastic cups. Culligan models break through traditional manufacturing processes, utilizing environmentally friendly R290 refrigerant and five preset modes (including juice and milkshake), resulting in 40dB silent operation and an 8-cup capacity. Their components are removable for cleaning and feature dual circuit protection. Some models utilize microcrystalline cooling technology to prevent dilution, balancing flavor preservation with ease of use.

[0003] In the prior art, when the length of the smoothie machine handle is detected in real time, the laser detector body itself is adaptively adjusted, so that the laser detector body is always in the external environment and exposed to the outside when the handle is switched between working and non-working states. There is a lack of protective equipment to adaptively protect it, resulting in a shortened service life of the laser detector body under long-term use and excessive strain. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a laser detection device for the length of an ice smoothie machine handle, which solves the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a laser detection device for the length of an ice sand machine handle, comprising an ice sand machine body, an operation panel is provided on the side of the ice sand machine body, an agitator, a stainless steel evaporator and a built-in compressor on the front and rear panels are provided inside the ice sand machine body, wherein the operation panel is electrically connected to the built-in compressor on the front and rear panels, a water receiving tray is fixedly connected to the side of the ice sand machine body, a material storage bucket is provided inside the ice sand machine body, a handle is provided on the side of the ice sand machine body, and a handle laser detection device is provided on one side of the ice sand machine body; the handle laser detection device The light detection device includes a protective shell, one end of which is fixedly connected to the side of the ice smoothie machine body, a detection port is opened on the side of the protective shell, one end of the detection port is slidably connected to a control panel, the side of the control panel is fixedly connected to a tether, the side of the handle is fixedly connected to a tether drum, one end of the tether is wound around the tether drum and fixedly connected to the inside of the rope groove of the tether drum, two fixing grooves are opened on the inner side surface of the protective shell, one of the fixing grooves is fixedly connected to a support plate, and the other fixing groove is rotatably connected to a fixed splint, and the bottom of the support plate is plugged with a laser detector body.

[0006] According to the above technical solution, a limiting slot is defined on the outer side of the protective shell, and the side of the control panel is slidably connected to the interior of the limiting slot. A return spring is fixedly connected to the side of the control panel, and one end of the return spring is fixedly connected to a spring fixing plate, and one end of the spring fixing plate is fixedly connected to the inner side of the limiting slot. The design of the return spring primarily utilizes its elasticity, so that when the tension of the tether is lost, the control panel is subjected to the elastic action of the return spring on the other side, causing it to reset horizontally and linearly. This reset horizontal linear motion of the control panel closes the detection port, allowing the laser detector body to be protected in the enclosed environment of the protective shell when the handle is not in operation. This adaptively adjusts the laser detector body itself, thereby increasing the service life of the laser detector body under long-term use.

[0007] According to the above technical solution, a limit plate is fixedly connected to the side of the protective shell. The limit plate is passed through by the tether and is not connected to the tether. The laser detector body is located directly to the side of the handle. The limit plate is designed to limit the displacement trajectory of the tether, thereby preventing the tether from getting stuck.

[0008] According to the above technical solution, a lens protection device is provided on the rear side of the control panel. The lens protection device includes a shielding plate and a transmission belt. The shielding plate is fixedly connected to the rear side of the control panel. The top of the shielding plate is fixedly connected to a gear block group. The inner side of the protective shell is rotatably connected to a connecting shaft. One end of the connecting shaft is fixedly connected to a transmission gear. One end of the transmission gear is fixedly connected to belt shaft 1. Belt shaft 1 is connected to belt shaft 2 via a transmission belt. One end of belt shaft 2 is fixedly connected to a transmission disc. One end of the transmission disc is fixedly connected to an eccentric shaft. One end of the eccentric shaft is fixedly connected to a protective plate. The design of the lens protection device is mainly to synchronize the closing of the handle laser detection device, shut down the laser detection end, and thus prevent the laser detection end from being exposed to the outside when the handle laser detection device is closed for a long time, causing lens contamination, which affects the detection effect of the next detection. At the same time, the laser detection end is protected from the front when it is closed, further improving the protection effect of the key parts of the laser detector body.

[0009] According to the above technical solution, the end of the transmission disc closest to the eccentric shaft is rotatably connected to a connecting plate, one end of which is fixedly connected to the inner side of the protective shell. The design of the connecting plate provides support for the transmission disc and the eccentric shaft, ensuring stable operation of the equipment.

[0010] According to the above technical solution, the transmission gear and the tooth block assembly mesh with each other, and one end of the protective plate initially abuts against the detection end of the laser detector body. This meshing ensures proper transmission between the transmission gear and the tooth block assembly. Initially, one end of the protective plate abuts against the detection end of the laser detector body, effectively protecting the lens of the laser detector body when it is closed.

[0011] According to the above technical solution, an adaptive sootblowing device is provided on the circumferential surface of the connecting shaft, and the adaptive sootblowing device includes an extrusion rod, the extrusion rod is fixedly connected to the circumferential surface of the connecting shaft, the inner side surface of the protective shell is fixedly connected to a fixed block, the inner side surface of the fixed block is fixedly penetrated by a piston tube, one end of the piston tube is connected to a piston rod through a piston sliding, and the other end of the piston tube is located on the side of the detection end of the laser detector body. The design of the adaptive sootblowing device is mainly to cooperate with the lens protection device. When the lens protection device is in the open state, the surface of the laser detector body is blown, and then the floating of the laser detector body is blown off, so that the laser detector body is more accurate in the state of the detection handle, and the difference in the detection value of the laser detector body caused by external factors is reduced.

[0012] According to the above technical solution, a tension spring is fixedly connected to the circumferential surface of the piston rod, and one end of the tension spring is fixedly connected to the end of the piston tube near the piston rod. The design of the tension spring mainly utilizes its elasticity to achieve the function of automatically resetting the piston tube.

[0013] According to the above technical solution, one end of the piston rod is located on the displacement track of the extrusion rod. Such a design enables the extrusion rod to stably squeeze one end of the piston rod during rotation and drive the piston rod to move.

[0014] The present invention provides a laser detection device for the handle length of an ice cream machine. It has the following beneficial effects: (1) The present invention sets a laser detection device on the handle, so that when the handle is pushed to reset the operation, the handle reverses and drives the rope reel to reverse, and the rope reel reverses and drives one end of the rope to loosen in the rope groove disc opened on the rope reel. At this time, the control board is elastically acted upon by the reset spring on the other side and performs reset horizontal linear motion. The reset horizontal linear motion of the control board closes the detection port, so that the laser detector body is protected in the closed environment of the protective shell when the handle is in the non-working state, and the laser detector body itself is adaptively adjusted to increase the service life of the laser detector body under long-term use.

[0015] (2) The present invention uses the setting of the lens protection device to synchronously shut down the handle laser detection device and the laser detection end, thereby preventing the lens from being contaminated by the laser detection end being exposed to the outside when the handle laser detection device is in a long-term shutdown state, thereby preventing the detection effect of the next detection from being affected. At the same time, the front protection of the laser detection end is performed in the closed state, thereby further improving the protection effect of the key parts of the laser detector body.

[0016] (3) The present invention adopts the setting of an adaptive soot blowing device in conjunction with the lens protection device. When the lens protection device is in the open state, the surface of the laser detector body is blown, thereby blowing off the floating and sinking on the surface of the laser detector body, making the laser detector body more accurate in the state of the detection handle, and reducing the difference in the detection value of the laser detector body caused by external factors.

One end of the return spring 911 is fixedly connected to the spring fixing plate 912. One end of the spring fixing plate 912 is fixedly connected to the inner side of the limit groove 910. The design of the return spring 911 primarily utilizes its elasticity, allowing the control panel 93 to perform a horizontal linear motion due to the elastic action of the return spring 911 on the other side when the tension of the tether 94 is lost. The control panel 93 performs a horizontal linear motion to close the detection port 92, allowing the laser detector body 99 to be protected in the enclosed environment of the protective shell 91 when the handle 8 is not in operation. The laser detector body 99 is adaptively adjusted to increase the service life of the laser detector body 99 under long-term use. A limit plate 913 is fixedly connected to the side of the protective shell 91. The limit plate 913 is penetrated by the tether 94 and has no connection with the tether 94. The laser detector body 99 is located directly to the side of the handle 8. The design of the limit plate 913 limits the displacement trajectory of the tether 94, thereby preventing the tether 94 from getting stuck.A lens protection device 10 is provided on the rear side of the control panel 93. The lens protection device 10 includes a baffle plate 101 and a transmission belt 1011. The baffle plate 101 is fixedly connected to the rear side of the control panel 93. The top of the baffle plate 101 is fixedly connected to a gear block group 102. The inner side of the protective shell 91 is rotatably connected to a connecting shaft 103. One end of the connecting shaft 103 is fixedly connected to a transmission gear 104. One end of the transmission gear 104 is fixedly connected to a belt shaft 105. The belt shaft 105 is connected to a belt shaft 2 106 through a transmission belt 1011. One end of the belt shaft 2 106 is fixedly connected to a transmission disc 107. One end of the transmission disc 107 is fixedly connected to an eccentric shaft 108. One end of the eccentric shaft 108 is fixedly connected to a protective plate 109. The design of the lens protection device 10 is mainly to synchronize the closing of the handle laser detection device 9 and the laser detection end, thereby preventing the lens from being contaminated by the exposure of the laser detection end when the handle laser detection device 9 is closed for a long time, affecting the detection effect of the next detection. At the same time, the laser detection end is protected from the front in the closed state, which once again improves the protection effect of the key parts of the laser detector body 99. The end of the transmission disc 107 close to the eccentric shaft 108 is rotatably connected to the connecting plate 1010, and one end of the connecting plate 1010 is fixedly connected to the inner side of the protective shell 91. The design of the connecting plate 1010 provides support for the transmission disc 107 and the eccentric shaft 108, ensuring the stable operation of the equipment. The transmission gear 104 and the gear block group 102 are meshed with each other, and one end of the protective plate 109 is in contact with the detection end of the laser detector body 99 in the initial state. The mutual engagement between the transmission gear 104 and the gear block group 102 ensures normal transmission between the transmission gear 104 and the gear block group 102. One end of the protective plate 109 is initially in contact with the detection end of the laser detector body 99, so that when the laser detector body 99 is in the closed state, the lens is effectively protected by the protective plate 109.

[0021] When using the ice machine body 1 to make ice, the staff operates the built-in compressor 5 on the front and rear panels through the operation panel 2 to start working, and the stainless steel evaporator 4 and the stirrer 3 are started at the same time to evaporate and stir the water. After the production is completed, the handle 8 is pulled, and the ice cubes in the storage bucket 7 fall above the water receiving tray 6; At the same time, pulling the handle 8 drives the rope drum 95 to rotate in the same direction. The rotation of the rope drum 95 drives one end of the rope 94 to be wound in the rope groove disk opened on the rope drum 95 and tightened, so that the other end pulls the control plate 93 to make horizontal linear motion inside the limit groove 910. The control plate 93 moves horizontally and linearly, and one end of the detection port 92 is opened synchronously, so that the laser detector body 99 fixed on the top of the support plate 97 detects the length change of the handle 8 in real time through the detection port 92 during the operation process, and then detects the real-time status of the handle 8 in real time according to the working trajectory of the handle 8 during operation. When the handle 8 is operated to reset, the handle 8 is reversed to drive the rope disc 95 to reverse, and the rope disc 95 reverses to drive one end of the rope 94 to loosen in the rope groove disc provided on the rope disc 95. At this time, the control board 93 is elastically acted upon by the reset spring 911 on the other side to perform reset horizontal linear motion. The control board 93 resets the horizontal linear motion to close the detection port 92, so that the laser detector body 99 is protected in the closed environment of the protective shell 91 when the handle 8 is not in operation. The laser detector body 99 itself is adaptively adjusted to increase the service life of the laser detector body 99 under long-term use. When the handle 8 is pulled to drive the rope disc 95 to rotate in the same direction, the control panel 93 performs horizontal linear motion, which drives the shielding plate 101 to perform horizontal linear motion. The horizontal linear motion of the shielding plate 101 drives the gear block group 102 to move horizontally. The horizontal linear motion of the gear block group 102 drives the transmission gear 104 meshing therewith to rotate. The rotation of the transmission gear 104 drives the belt shaft 105 to rotate. The rotation of the belt shaft 105 drives the belt shaft 2 106 to rotate in the same direction through the transmission belt 1011. The belt shaft 2 106 rotates in the same direction and drives the transmission disc 107 rotates, the transmission disc 107 rotates to drive the eccentric shaft 108 to rotate eccentrically, the eccentric shaft 108 rotates eccentrically to drive the protective plate 109 to rotate, the protective plate 109 rotates to open the detection end of the laser detector body 99, and then the handle laser detection device 9 is started synchronously, and the laser detection end is turned on. When the handle 8 is pushed to drive the rope disk 95 to rotate in the same direction, the control board 93 resets the horizontal linear motion, which drives the shielding plate 101 to reset the horizontal linear motion. At this time, the handle laser detection device 9 is in the normally closed state, and the shielding plate 101 is The horizontal linear motion is reset, and the baffle plate 101 resets the horizontal linear motion, driving the gear block group 102 to reset the horizontal linear motion. The gear block group 102 resets the horizontal linear motion and drives the transmission gear 104 meshing with it to rotate in the opposite direction. The transmission gear 104 rotates in the opposite direction and drives the belt shaft 1 105 to rotate in the opposite direction. The belt shaft 1 105 rotates in the opposite direction and drives the belt shaft 2 106 to rotate in the opposite direction through the transmission belt 1011. The belt shaft 2 106 rotates in the opposite direction and drives the transmission disc 107 to rotate in the opposite direction. The transmission disc 107 rotates in the opposite direction and drives the eccentric shaft 108 to rotate in the opposite direction eccentrically. The eccentric shaft 108 rotates in the opposite direction and drives the protective plate 109 to rotate in the opposite direction. The protective plate 109 rotates in the opposite direction to close the detection end of the laser detector body 99, and then synchronously closes the handle laser detection device 9, closes the laser detection end, and prevents the lens from being contaminated by the exposure of the laser detection end when the handle laser detection device 9 is closed for a long time, affecting the detection effect of the next detection. At the same time, the laser detection end is protected from the front in the closed state, which once again improves the protection effect of the key parts of the laser detector body 99.

[0022] See also Figure 1-8In another embodiment of the present invention, based on the above embodiment, an adaptive sootblowing device 11 is provided on the circumferential surface of the connecting shaft 103. The adaptive sootblowing device 11 includes a squeeze rod 111 fixedly connected to the circumferential surface of the connecting shaft 103. A fixing block 112 is fixedly connected to the inner side of the protective shell 91. A piston tube 113 is fixedly inserted through the inner side of the fixing block 112. One end of the piston tube 113 is slidably connected to a piston rod 114 via a piston. The other end of the piston tube 113 is located on the side of the detection end of the laser detector body 99. The adaptive sootblowing device 11 is designed primarily to cooperate with the lens protection device 10. When the lens protection device 10 is in the open state, it blows on the surface of the laser detector body 99, thereby blowing away any surface fluctuations of the laser detector body 99. This makes the laser detector body 99 more accurate when the detection handle 8 is engaged, thereby reducing the difference in the detection value of the laser detector body 99 caused by external factors. A tension spring 115 is fixedly attached to the circumference of piston rod 114. One end of tension spring 115 is fixedly connected to the end of piston tube 113 closest to piston rod 114. The design of tension spring 115 primarily utilizes its elasticity to automatically reset piston tube 113. One end of piston rod 114 is located along the displacement path of extrusion rod 111. This design ensures that extrusion rod 111 can stably compress one end of piston rod 114 during rotation, driving piston rod 114's displacement.

[0023] When in use, when the transmission gear 104 rotates, it drives the connecting shaft 103 to rotate, and the rotation of the connecting shaft 103 drives the extrusion rod 111 to rotate, and the extrusion rod 111 rotates and squeezes one end of the piston tube 113. One end of the piston tube 113 is squeezed and displaced horizontally toward the inside of the piston tube 113. The piston tube 113 displaces horizontally to squeeze the gas inside the piston tube 113, and releases and discharges the gas through the other end of the piston tube 113 to blow on the surface of the laser detector body 99, blowing off the dust attached to the surface of the laser detector body 99. When one end of the piston tube 113 is no longer subjected to the extrusion force from the extrusion rod 111, it will be driven by the elastic action of the tension spring 115 to reset itself, thereby achieving the effect of being cyclically subjected to the extrusion force of the extrusion rod 111, so that the piston tube 113 is horizontally displaced to squeeze the gas inside the piston tube 113, and releases and discharges the gas through the other end of the piston tube 113 to blow on the surface of the laser detector body 99, which can be recycled, thereby increasing the effect of removing dust from the surface of the laser detector body 99.
