Description

Technical Field

[0001] This application relates to the textile industry, and in particular to a fabric delivery cart. Background Technology

[0002] Fabric delivery carts are typically used for short-distance fabric transport. The fabric is placed on the base of the cart, and the cart is moved by pushing the push handle of the fabric delivery clown.

[0003] In order to improve conveying efficiency, too much fabric is often placed on the fabric feeding trolley at once. However, placing too much fabric can not only make the fabric feeding trolley difficult to push, but may even damage the fabric feeding trolley in severe cases. Utility Model Content

[0004] In order to maintain the quality of the fabric on the fabric feeding trolley within a certain range, this application provides a fabric feeding trolley.

[0005] The technical solution of the fabric feeding trolley provided in this application is as follows: A fabric feeding trolley includes a frame, the lower end of the frame is provided with rollers, the frame is slidably connected to a sliding rod in the vertical direction, the upper end of the sliding rod is provided with a load-bearing plate, the lower end of the sliding rod passes through the frame and is located below the frame, and a first spring for supporting the load-bearing plate is provided between the load-bearing plate and the frame.

[0006] By adopting the above technical solution, when the cloth is placed on the load-bearing plate, the load-bearing plate compresses the first spring and drives the sliding rod to move downward. When the weight of the cloth is too heavy, the sliding rod moves downward and touches the ground, making it difficult for the cloth feeding trolley to move, thereby reminding the operator that the cloth is too heavy.

[0007] Optionally, the lower end of the sliding rod is provided with a horizontal friction plate.

[0008] By adopting the above technical solution, the friction plate enhances the friction with the ground, making it difficult for the fabric delivery trolley to move.

[0009] Optionally, a switch is provided at the lower end of the friction plate. The switch is electrically connected to the controller and sends an electrical signal to the controller when the friction plate contacts the ground. The controller is electrically connected to an alarm and controls the alarm to sound an alarm when it receives the electrical signal.

[0010] By adopting the above technical solution, when the rubbing plate touches the ground, the switch is turned on, causing the alarm to sound, thereby reminding the operator that the cloth is too heavy.

[0011] Optionally, the switch includes a slider, a pressure sensor, and a second spring. A vertical sliding groove is provided at the lower end of the friction plate. The slider slides vertically and is connected to the sliding groove. The pressure sensor is located on the inner top wall of the sliding groove and is electrically connected to the controller. The slider is connected to the pressure sensor through the second spring, which is used to maintain the lower end of the slider below the lower end of the friction plate.

[0012] By adopting the above technical solution, when the friction plate touches the ground, the slider moves upward and compresses the second spring. The second spring applies pressure to the pressure sensor, thereby causing the pressure sensor to send an electrical signal to the controller.

[0013] Optionally, the lower end of the friction plate is provided with a rubber layer, which covers the slider.

[0014] By adopting the above technical solution, the rubber layer plays a role in protecting the slider and reducing the occurrence of slider damage.

[0015] Optionally, the first spring is sleeved outside the sliding rod.

[0016] By adopting the above technical solution, the sliding rod plays a supporting role for the first spring, reducing the possibility of the first spring bending.

[0017] Optionally, the load-bearing plate is provided with a protective plate around its circumference, and the protective plate is arranged vertically downwards.

[0018] By adopting the above technical solution, the protective plate plays a role in protecting the first spring and reducing the impact on the first spring.

[0019] Optionally, the lower end of the protective plate is provided with a rubber pad.

[0020] By adopting the above technical solution, the rubber pads play a role in protecting operators and reducing the possibility of injury to operators caused by the protective plate pressing on their feet when it moves downwards.

[0021] In summary, this application includes at least one of the following beneficial technical effects: When the fabric is placed on the load-bearing plate, the load-bearing plate compresses the first spring and drives the sliding rod to move downward. When the weight of the fabric is too heavy, the sliding rod moves downward and touches the ground, making it difficult for the fabric feeding trolley to move, thus reminding the operator that the fabric is too heavy. When the friction plate touches the ground, the slider moves upward and compresses the second spring. The second spring applies pressure to the pressure sensor, which in turn sends an electrical signal to the controller. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses a fabric delivery trolley. (Refer to...) Figure 1 , Figure 2 as well as Figure 3 A fabric feeding trolley includes a horizontal frame 1, with rollers 11 installed at the lower end of the frame 1 and a handle installed at one end of the frame 1. Each of the four corners of the frame 1 is slidably connected to a sliding rod 2 in the vertical direction. The lower end of the sliding rod 2 passes through the frame 1 and is located below the frame 1. The upper end of the sliding rod 2 is fixedly connected to a load-bearing plate 3, which is used to place fabric. A first spring 31 is sleeved on the sliding rod 2. The upper end of the first spring 31 is connected to the load-bearing plate 3, and the lower end of the first spring 31 is connected to the frame 1. The first spring 31 provides support for the load-bearing plate 3. When fabric is placed on the load-bearing plate 3, the load-bearing plate 3 compresses the first spring 31 downward and drives the sliding rod 2 to move downward.

[0028] Reference Figure 1 , Figure 2 as well as Figure 3A horizontal friction plate 4 is installed at the lower end of the sliding rod 2. The friction plate 4 enhances the friction with the ground. A switch 5 is installed at the lower end of the friction plate 4. The switch 5 includes a slider 51, a pressure sensor 53, and a second spring 52. A vertical sliding groove 41 is opened at the lower end of the friction plate 4. The slider 51 slides vertically and is connected to the sliding groove 41. The pressure sensor 53 is installed on the inner top wall of the sliding groove 41. The slider 51 is connected to the pressure sensor 53 through the second spring 52. The second spring 52 is used to maintain the state where the lower end of the slider 51 is lower than the lower end of the friction plate 4. When the weight of the cloth on the load-bearing plate 3... When the weight is too heavy, the sliding rod 2 moves downward and causes the friction plate 4 to contact the ground, making it difficult for the fabric feeding trolley to move. When the friction plate 4 contacts the ground, the slider 51 moves upward and presses the pressure sensor 53 through the second spring 52. The pressure sensor 53 is electrically connected to the controller 6 and sends the pressure value to the controller 6. The controller 6 is electrically connected to the alarm 7 and, after receiving the electrical signal, controls the alarm 7 to sound an alarm, reminding the operator that the fabric on the fabric feeding trolley is too heavy. A rubber layer 42 is installed at the lower end of the friction plate 4. The rubber layer 42 covers the slider 51 and the sliding groove 41, which serves to protect the slider 51.

[0029] Reference Figure 1 , Figure 2 as well as Figure 3 The load-bearing plate 3 is circumferentially fixedly connected to a protective plate 32. The protective plate 32 is set vertically downward and covers the first spring 31 to reduce the damage to the first spring 31 caused by impact. A rubber pad 33 is installed at the lower end of the protective plate 32 to reduce the injury caused by the protective plate 32 pressing on the operator's foot when it moves downward.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
