Description

Technical Field

[0001] The utility model relates to the technical field of recycling machines, and particularly to a dual-screen cash register type recycling machine. Background Art

[0002] The dual-screen cash register type recycling machine is a kind of cash register equipment in the cash register system of waste recycling stations. It can be externally connected with a weighing device, a barcode scanner, and a receipt printer, and can be connected to a network camera for taking pictures. The equipment automatically weighs, captures pictures, automatically settles accounts, and transmits data to the background in real time. It has two operation screens, one facing the purchaser and the other facing the customer, enabling the customer to understand the purchase information.

[0003] However, when the existing dual-screen cash register type recycling machine is in use, since the positions of the two screens of the dual-screen cash register type recycling machine are fixed, the purchaser always needs to stand to operate the dual-screen cash register type recycling machine, which is inconvenient for the purchaser. Or it has the function of adjusting the height, but the two screens are adjusted synchronously, that is, when one screen moves, the height of the other screen will change synchronously. Since the purchaser always operates in front of the dual-screen cash register type recycling machine, after standing for a long time, the purchaser will sit down to rest and operate the dual-screen cash register type recycling machine. After sitting and standing for a long time, the purchaser will adjust the posture and stand up to operate. Then, when the purchaser adjusts the posture, if the angle of the screen of the dual-screen cash register type recycling machine is changed, the height of the screen facing the customer will also change. If the purchaser is in a standing state, since the customer is also in a standing state, the height of the screen has no influence on both parties at this time. If the purchaser is in a sitting state, the height of the screen is relatively low, which is not convenient for the customer to observe the situation on the dual-screen cash register type recycling machine. Therefore, a dual-screen cash register type recycling machine that can freely change the height of the two screens and does not interfere with each other is proposed to facilitate the use of the purchaser and the customer.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to visually and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: a dual-screen cash register type recycling machine, including a base 1, a bracket 5 is fixedly connected to the surface of the base 1, two lifting rods 7 are slidably connected inside the bracket 5, and operation screens 6 are fixedly connected to the opposite ends of the two lifting rods 7, so that both the recycling personnel and the customers can view the information.

[0025] There are two fixing mechanisms arranged inside the base 1. The fixing mechanism includes two racks 10. The surfaces of the two racks 10 are both slidably connected to the inside of the base 1. A gear 8 is rotatably connected to the inside of the base 1. The gear 8 is located between the two racks 10. The surface of the gear 8 is meshed with the surfaces of the two racks 10. Fixed blocks 3 are fixedly connected to the opposite ends of the two racks 10. A slider 4 is slidably connected to the inside of the fixed block 3, which is used to hook the placement tabletop of the base 1 to fix the device. One end of the slider 4 located inside the fixed block 3 is fixedly connected to a first spring 9. The end of the first spring 9 away from the slider 4 is fixedly connected to the inside of the fixed block 3, which is used to reset the slider 4. When the device is placed on the tabletop, blocked by the tabletop, the slider 4 retracts into the fixed block 3 and compresses the first spring 9.

[0026] Furthermore, a threaded rod 2 is threadedly connected to the inside of the base 1. The surface of the threaded rod 2 is slidably connected to the inner wall of the gear 8. The threaded rod 2 and the inner wall of the gear 8 are connected by a spline, so that when the threaded rod 2 rotates, it can synchronously drive the gear 8 to rotate, and at the same time, it does not affect the mutual sliding between the threaded rod 2 and the gear 8. Secondly, through the setting of the threaded rod 2, the self-locking property of the thread can be utilized to realize the restriction of the rotation of the gear 8, avoiding the random rotation of the gear 8 during use and ensuring the stability of the connection between the device and the tabletop.

[0027] Two rotating shafts 12 are rotatably connected to the inside of the bracket 5. The structures on the two rotating shafts 12 are the same. A spiral groove 18 is formed on the surface of the rotating shaft 12. A sliding block 13 is fixedly connected to the surface of the lifting rod 7. The surface of the sliding block 13 is slidably connected to the inside of the bracket 5. The surface of the sliding block 13 slides on the surface of the rotating shaft 12. A fixing rod 19 is fixedly connected to the inner wall of the sliding block 13. The surface of the fixing rod 19 slides on the inner wall of the spiral groove 18. Therefore, when the user pulls the operation screen 6 to drive the sliding block 13 to slide in the bracket 5, the rotating shaft 12 can be driven to rotate synchronously by the extrusion of the fixing rod 19 on the inner wall of the spiral groove 18, thus ensuring the smooth operation of the device.

[0028] Furthermore, a rotating disk 14 is arranged at the upper end of the rotating shaft 12. A plurality of clamping blocks 15 arranged at equal circumferential intervals are slidably connected to the surface of the rotating disk 14. The cross section of the clamping block 15 is a right trapezoid. A plurality of clamping grooves 17 arranged at equal circumferential intervals are formed in the inside of the rotating shaft 12. The surface of the clamping block 15 slides on the inner wall of the clamping groove 17. A second spring 16 is fixedly connected to the surface of the clamping block 15 located inside the rotating disk 14. The end of the second spring 16 away from the clamping block 15 is fixedly connected to the inside of the rotating disk 14, which is used to reset the clamping block 15.

[0029] The surface of the support 5 is slidably connected with a U-shaped rod 11. One end of the U-shaped rod 11 far from the support 5 is fixedly connected with the surface of the rotating disk 14. A second spring 16 is also arranged between the U-shaped rod 11 and the inside of the support 5 to limit the position of the U-shaped rod 11, avoiding the random movement of the U-shaped rod 11 on the support 5. At the same time, the setting of the U-shaped rod 11 can fix the rotating disk 14.

[0030] Specifically, when fixing the device, the staff can rotate the threaded rod 2 to drive the gear 8 to rotate, and then drive the two racks 10 to move away from each other, so as to drive the two sliders 4 to gradually approach the edge of the table. When the sliders 4 protrude from the table, under the elastic force of the first spring 9, the sliders 4 return to their original state, so as to hook the surface of the table. Then the user can reverse the threaded rod 2 to drive the two sliders 4 to move relatively, improving the tightness between the sliders 4 and the table, so as to connect the device with the table, avoiding the situation that when the user adjusts the height of the operation screen 6 later, the whole device moves, affecting the use stability of the device.

[0031] Secondly, when it is necessary to adjust the height of the operation screen 6, when it is necessary to raise the position of the operation screen 6, pull up the operation screen 6 to be adjusted, so as to drive the lifting rod 7 and the sliding block 13 to slide up in the support 5. At the same time, the fixing rod 19 slides in the spiral groove 18, and then drives the rotating shaft 12 to rotate synchronously, so that the inner wall of the card slot 17 pushes and squeezes the inclined surface of the card block 15, making the card block 15 retract into the rotating disk 14 and compressing the second spring 16 until the card block 15 corresponds to another card slot 17. Under the elastic force of the second spring 16, the card block 15 is pushed into another card slot 17, so as not to affect the rotation of the rotating shaft 12, and then the operation screen 6 can be smoothly raised. At the same time, because the vertical surface of the card block 15 abuts against the inner wall of the card slot 17, the rotating shaft 12 cannot be reversed, so that after the operation screen 6 is raised, the operation screen 6 will not automatically slide down under the action of gravity, ensuring the adjustment effect of the device.

[0032] When it is necessary to lower the operation screen 6, the user can pull the U-shaped rod 11, and then drive the rotating disk 14 to disengage from the rotating shaft 12, so that the reverse rotation of the rotating shaft 12 is no longer blocked. At this time, the user can press the operation screen 6 to adjust the height of the operation screen 6. Therefore, when the device is in use, the user can adjust the heights of the two operation screens 6 according to the viewing comfort of the customer and the acquirer, so that the acquirer can conveniently operate the operation screen 6 whether sitting or standing, thus improving the use effect of the device and being worthy of promotion.

[0033] Working principle: When it is necessary to adjust the height of the operation screen 6 and raise the position of the operation screen 6, pull up the operation screen 6 to be adjusted, thereby driving the lifting rod 7 and the sliding block 13 to slide upward in the bracket 5. At the same time, the fixed rod 19 slides in the spiral groove 18, thereby driving the rotating shaft 12 to rotate synchronously, so that the inner wall of the card slot 17 pushes and squeezes the inclined surface of the card block 15, causing the card block 15 to retract into the rotating disc 14 and compress the second spring 16. Until the card block 15 corresponds to another card slot 17, under the elastic force of the second spring 16, the card block 15 is pushed into another card slot 17, so as not to affect the rotation of the rotating shaft 12, and then the operation screen 6 can be smoothly raised. At the same time, since the vertical surface of the card block 15 abuts against the inner wall of the card slot 17, the rotating shaft 12 cannot reverse, and then after the operation screen 6 is raised, the operation screen 6 will not automatically slide down under the action of gravity.

[0034] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
