Hide Splitting Machine Belt Centering and Cutting Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hide splitting machines face safety risks for operators due to manual handling of hides, belt contact with the cutting blade leading to reduced efficiency and durability, and frequent belt misalignment causing productivity issues, while also having large dimensions and complex maintenance.
Innovation Solution
An industrial hide splitting machine design featuring a load-bearing frame with adjustable rollers and a flexible hide spreading member, allowing for automatic belt centering and easy replacement, along with a compensation roller for thickness calibration and depression prevention, ensuring the integrity of the infeed belt and reducing manual hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cutting blade is positioned close to the infeed belt for precision cutting, then cutting precision is improved, but the infeed belt is exposed to accidental contact and damage
Solution Approach 1:
A protective plate is introduced as an intermediary element positioned between the infeed belt and the cutting blade. This plate serves as a physical barrier that prevents direct contact between the belt and blade while allowing the blade to maintain its precise cutting position close to the belt surface.
Solution Approach 2:
The protective plate is installed in advance to prevent potential damage to the infeed belt. By having this protective element in place before any accidental contact can occur, the system proactively safeguards against belt damage that would otherwise reduce productivity and increase maintenance costs.
2Ease of operation
If the upper feeding belt is allowed to move freely under hide stress, then ease of operation is improved, but the belt slips sideways and requires frequent manual recentering
Solution Approach 1:
The lateral support shoulders are designed to dynamically adjust their position and provide variable resistance to belt movement. The support mechanism changes the operational parameters of the belt by allowing controlled movement within certain limits while automatically preventing excessive lateral displacement, thus maintaining productivity without compromising operational ease.
3Ease of operation
If manual handling of hides is used to guide them toward the cutting blade, then ease of operation is improved, but operator safety is compromised
Solution Approach 1:
The infeed belt system is designed to automatically perform the function of guiding hides toward the cutting blade without requiring manual intervention. The belt's movement and the associated guide rollers work together to self-guid e the hide through the cutting zone, eliminating the need for operators to place their hands near the blade area.
4Volume of moving object
If the machine is designed with compact dimensions, then space efficiency is improved, but the belt arrangement becomes more complex
Solution Approach 1:
The protective plate is integrated with the existing belt support structure, merging two functions into a single component arrangement. The plate is positioned to work in conjunction with the guide rollers and support shoulders, creating a compact assembly that provides both protection and structural support without adding significant volume or complexity to the machine design.

AI summary
An industrial hide splitting machine (1), comprising an infeed table (2) for infeeding the hide (P), which has an infeed belt (4) with a hide receiving surface (5) for hide to be positioned thereon, a driving head (3) located above the infeed table (2) with a feeding belt (6) wound in a closed-loop configuration around first support roller means (7) and adapted to cooperate with the infeed belt (4) to cause the hide (P) to be fed in a predetermined feed direction (D). The feeding belt (6) has a lower surface (8) facing the receiving surface (5) of the infeed belt (4) to define a gap (9) therewith for receiving the hide (P). The machine (1) further comprises a pair of mutually opposed guide rollers (10, 11), adapted to rotate about respective rotation axes transverse to the feed direction (D) to define an outlet (12) for the hide (P) to be cut and a cutting device (13) located downstream of the outlet (12) with respect to the feed direction (D). The infeed belt (4) is wound in a closed-loop configuration around second support roller means (19) and has an outfeed section (20) for outfeeding the hide (P), which is located upstream of the outlet (12) defined by the pair of guide rollers (10, 11) and faces it at such a distance as to be spaced apart from the cutting device (13) and not in contact therewith.
