Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of water-isolating sheets, in particular to a clamping and fixing device for production and processing of water-isolating sheets. Background Art

[0002] Barriers are primarily used in luggage to enhance its water resistance and protect items from moisture and damage. They are typically located inside the luggage, fitting snugly against the outer shell to create an additional waterproof layer. Hardside luggage typically features rigid barriers for added protection and structural integrity, while softside luggage may feature flexible barriers to provide waterproofing while maintaining a degree of flexibility.

[0003] Cutting the flexible baffle is an important step in processing the flexible baffle. However, in the process of cutting the flexible baffle, because the flexible baffle is relatively soft and cannot be fixed at one end like the hard baffle to prevent it from deflecting, it is easy to deflect during the cutting process, affecting the cutting accuracy.

[0004] Therefore, in view of the problem that the above-mentioned flexible water-blocking sheet is relatively soft and easily deflected during the cutting process, which affects the cutting accuracy, a clamping and fixing device for the production and processing of water-blocking sheets can be designed to solve the above-mentioned problem. Utility Model Content

[0005] In order to overcome the problem that in the process of cutting flexible waterproof sheets, the flexible waterproof sheets are relatively soft and cannot be fixed at one end like hard waterproof sheets to prevent them from deflecting, which makes them prone to deflection during the cutting process and affects the cutting accuracy.

[0007] Preferably, the second threaded shaft and the third threaded shaft are screwed according to the thickness of the water barrier to change the height of the first double-axis frame conveyor belt and the first double-axis frame conveyor belt, thereby changing the clamping force of the water barrier, and then the positions of the push strips on both sides are adjusted by screwing the first threaded shaft so that the distance between the two is equal to the width of the water barrier, and then the water barrier is placed between the two push strips, and the first double-axis frame conveyor belt with the connecting rod as the rotating axis is lowered horizontally, and the second double-axis frame conveyor belt is pressed down by the pressing plate to make the water barrier close to the front pad wheel.

[0008] Preferably, the rear end of the second threaded shaft is provided with a third threaded shaft rotatably connected to the chassis; the rear end of the third threaded shaft is provided with a sliding rod fixed to the chassis; the sliding rod is slidably connected to the second double-axis frame conveyor belt; the second double-axis frame conveyor belt is clearance-matched with the third threaded shaft.

[0009] Preferably, a cutting slot is provided at the rear end of the chassis, and three double-petal pads are provided at the rear end of the front pads, which are rotatably connected to the chassis. The cutter cuts the water barrier at the location of the cutting slot.

[0010] Preferably, a gear shaft is fixedly connected to one side of the front washer wheel and the double-flap washer wheel; the gear shafts extend through the chassis; a chain is meshed with one side of the gear shafts; a motor is fixedly connected to one side of the chassis; the motor is rotationally connected to the gear shaft via a connecting shaft and a coupling. When the motor is started, the motor rotates together through the gear shaft and the chain, causing the clamped water barrier to move rearward under the action of the front washer wheel and the double-flap washer wheel, and is cut while being clamped by the second double-shaft frame conveyor belt. Thus, the water barrier remains clamped during the processing process, preventing it from shifting.

[0011] Preferably, the front ends of the second threaded shafts are each provided with a fixed block fixed to the chassis; the two first threaded shafts are each loosely fitted on the fixed block. After the rear end of the water barrier is clamped by the second dual-axis frame conveyor belt, the pressure on the first dual-axis frame conveyor belt can be stopped, thereby simplifying operation.

[0012] Preferably, the two first threaded shafts on the same side are arranged in the same group, and the same push bar is rotatably connected to each group of first threaded shafts.

[0013] Preferably, the double-petal pad wheel is arranged inside the chassis; the double-petal pad wheel consists of two pulleys connected to each other by a rotating shaft.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting up a double clamping component and a side drive component, the device can limit the angle of the water barrier when the user places the water barrier.

[0016] 2.

[0017] 3. After the rear end of the water barrier has been clamped by the second double-axis frame conveyor belt, the pressing of the first double-axis frame conveyor belt can be stopped, thereby simplifying the operation. BRIEF DESCRIPTION OF THE DRAWINGS
